| 1 | Comparison of the effect and safety of Kuntai capsule and hormone replacement therapy in patients with perimenopausal syndrome:a systematic review and Meta-analysis显示文摘OBJECTIVE: To assess the effectiveness and safety of Kuntai capsule and hormone replacement therapy in treatment of perimenopausal syndrome.METHODS: Articles were retrieved from the databases Cochrane Database of Systematic Reviews,Pub Med, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database. Only randomized controlled trials were included; 15 trials involving1243 patients were identified from January 2005 to April 2015. A systemic review and Meta-analysis of publications was performed. The review was limit-ed to randomized controlled trials that compared Kuntai capsule and hormone replacement therapy to treat perimenopausal syndrome for at least 3months. The primary outcome assessed was the treatment efficacy at 3 months, including effective rate of Kupperman menopausal scores, Kupperman menopausal scores, and blood estradiol(E2) or blood follicle stimulating hormone(FSH) levels.Other outcomes assessed were safety or adverse events, such as gastrointestinal complaints, breast distending pain, or vaginal bleeding.RESULTS: Kupperman menopausal scores showed no significant difference in effective rate [odds ratio(OR): 1.05, 95% confidence intervals(CI): 0.71 to1.55] and changes in FSH level [mean difference(MD): 2.14, 95% CI:-2.36 to 6.65]. There was a significant statistical difference in Kupperman menopausal scores(MD:-1.14, 95% CI:-2.03 to-0.25)and changes in E2level(MD:-16.41, 95% CI:-18.83to-13.69). There were fewer adverse events in the Kuntai capsule group than in the hormone replacement therapy group(OR: = 0.35, 95% CI: 0.25 to0.48, P < 0.01).CONCLUSION: Compared with hormone replacement therapy, Kuntai capsule can improve perimenopausal symptoms and blood E2 levels, and reduce the incidence of adverse events. | Du Xiaoqin Xu Lin Wang Lijun Heng Mingli Bu Huaien Hao Yu Tian Jinhui | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 28 |
| 2 | Technology and Experiments of 42CrMo Bearing Ring Forming Based on Casting Ring Blank显示文摘Bearing ring is the crucial component of bearing. With regard to such problems as material waste, low efficiency and high energy consumption in current process of producing large bearing ring, a new process named 'casting-rolling compound forming technology' is researched by taking the typical 42CrMo slew bearing as object. Through theoretical analysis, the design criteria of the main casting-rolling forming parameters are put forward at first. Then the constitutive relationship model of as-cast 42CrMo steel and its mathematical model of dynamic recrystallization are obtained according to the results of the hot compression experiment. By a coupled thermal-mechanical finite element model for radial-axial rolling of bearing ring, the fraction of dynamic recrystallization is calculated and recrystallized grains size are predicated. Meanwhile, the effects of the initial rolling temperature and feed rate of idle roll on material microstructure evolution are analyzed. Finally, the industrial rolling experiment is designed and performed, based on the simulation results. In addition, mechanical and metallographic tests are conducted on rolled bearing ring to get the mechanical parameters and metallographic structure. The experimental data and results show that the mechanical properties of bearing ring produced by casting-rolling compound forming technology are up to industrial standard, and a qualified bearing ring can be successfully formed by employing this new technology. Through the study, a process of forming large bearing ring directly by using casting ring blank is obtained, which could provide an effective theoretical guidance for manufacturing large ring parts. It also has an edge in saving material, lowering energy and improving efficiency. | LI Yongtang JU Li QI Huiping ZHANG Feng CHEN Guozhen WANG Mingli | 2014 | Chinese Journal of Mechanical Engineering2014，27，2： | 16 |
| 3 | Nitrogen-doped fluorescence carbon dots as multi-mechanism detection for iodide and curcumin in biological and food samples显示文摘Iodine ion is one of the most indispensable anions in living organisms,particularly being an important substance for the synthesis of thyroid hormones.Curcumin is a yellow-orange polyphenol compound derived from the rhizome of Curcuma longa L.,which has been commonly used as a spice and natural coloring agent,food additives,cosmetics as well as Chinese medicine.However,excess curcumin may cause DNA inactivation,lead to a decrease in intracellular ATP levels,and trigger the tissue necrosis.Therefore,quantitative detection of iodine and curcumin is of great significance in the fields of food and life sciences.Herein,we develop nitrogen-doped fluorescent carbon dots(NCDs)as a multi-mechanism detection for iodide and curcumin in actual complex biological and food samples,which was prepared by a one-step solid-phase synthesis using tartaric acid and urea as precursors without adding any other reagents.An assembled NCDs-Hg^(2+) fluorescence-enhanced sensor for the quantitative detection of I^(-) was established based on a fluorescence“turn-off-on”mechanism in a linear range of 0.3-15μM with a detection limit of 69.4 nM and successfully quantified trace amounts of I^(-) in water samples and urine sample.Meanwhile,the as-synthesized NCDs also can be used as a fluorescent quenched sensor for curcumin detection based on the synergistic internal filtration effect(IFE)and static quenching,achieving a good linear range of 0.1-20μM with a satisfactory detection limit of 29.8 nM.These results indicate that carbon dots are potential sensing materials for iodine and curcumin detection for the good of our health. | Xiaodan Tang Hongmei Yu Brian Bui Lingyun Wang Christina Xing Shaoyan Wang Mingli Chen Zhizhi Hu Wei Chen | 2021 | Bioactive Materials2021，6，6： | 11 |
| 4 | Adsorption of VOCs on reduced graphene oxide显示文摘A modified Hummer's method was adopted for the synthesis of graphene oxide(GO) and reduced graphene oxide(rGO). It was revealed that the modified method is effective for the production of GO and rGO from graphite. Transmission electron microscopy(TEM) images of GO and rGO showed a sheet-like morphology. Because of the presence of oxygenated functional groups on the carbon surface, the interlayer spacing of the prepared GO was higher than that of rGO. The presence of \OH and C_O groups in the Fourier transform infrared spectra(FTIR) spectrum and G-mode and 2D-mode in Raman spectra confirmed the synthesis of GO and rGO. rGO(292.6 m^2/g) showed higher surface area than that of GO(236.4 m^2/g). The prepared rGO was used as an adsorbent for benzene and toluene(model pollutants of volatile organic compounds(VOCs)) under dynamic adsorption/desorption conditions. rGO showed higher adsorption capacity and breakthrough times than GO. The adsorption capacity of rGO for benzene and toluene was 276.4 and 304.4 mg/g, respectively.Desorption experiments showed that the spent rGO can be successfully regenerated by heating at 150.0°C. Its excellent adsorption/desorption performance for benzene and toluene makes rGO a potential adsorbent for VOC adsorption. | Lian Yu Long Wang Weicheng Xu Limin Chen Mingli Fu Junliang Wu Daiqi Ye | 2018 | Journal of Environmental Sciences2018，30，5： | 10 |

| 6 | Target delineation and dose prescription of adaptive replanning intensity-modulated radiotherapy for nasopharyngeal carcinoma显示文摘Dear Editor,Intensity-modulated radiotherapy(IMRT)has a distinct advantage of high conformity and is an appropriate tech-nique for treating nasopharyngeal carcinoma(NPC).Pre-vious studies have demonstrated that anatomical changes in the external contour,shape,and location of the target and critical structures are significant and result in dosi-metric changes[1,2].Patients’quality of life and clini-cal outcomes might be improved by IMRT replanning[3].Therefore,replanning strategies should be consid-ered instead of single-planning strategies throughout the entire course of radiotherapy.However,there are sub-stantial controversies on(1)the appropriate time for tar-get redelineation,(2)how to modify the target volumes,and(3)how to evaluate the modified plans.The present study provides a new perspective in replanning with regard to these three aspects. | Dehuan Xie Wanqin Cheng Shaowen Lv Rui Zhong Lei Wang Jiang Hu Mingli Wang Shaomin Huang Yong Su Yunfei Xia | 2019 | Cancer Communications2019，39，1： | 7 |

| 8 | Neurocognitive Graphs of First-Episode Schizophrenia and Major Depression Based on Cognitive Features显示文摘Neurocognitive deficits are frequently observed in patients with schizophrenia and major depressive disorder(MDD). The relations between cognitive features may be represented by neurocognitive graphs based on cognitive features, modeled as Gaussian Markov random fields. However, it is unclear whether it is possible to differentiate between phenotypic patterns associated with the differential diagnosis of schizophrenia and depression using this neurocognitive graph approach. In this study, we enrolled 215 first-episode patients with schizophrenia(FES), 125 with MDD, and 237 demographically-matched healthy controls(HCs). The cognitive performance of all participants was evaluated using a battery of neurocognitive tests. The graphical LASSO model was trained with aone-vs-one scenario to learn the conditional independent structure of neurocognitive features of each group. Participants in the holdout dataset were classified into different groups with the highest likelihood. A partial correlation matrix was transformed from the graphical model to further explore the neurocognitive graph for each group. The classification approach identified the diagnostic class for individuals with an average accuracy of 73.41% for FES vs HC, 67.07% for MDD vs HC, and 59.48% for FES vs MDD. Both of the neurocognitive graphs for FES and MDD had more connections and higher node centrality than those for HC. The neurocognitive graph for FES was less sparse and had more connections than that for MDD.Thus, neurocognitive graphs based on cognitive features are promising for describing endophenotypes that may discriminate schizophrenia from depression. | Sugai Liang Roberto Vega Xiangzhen Kong Wei Deng Qiang Wang Xiaohong Ma Mingli Li Xun Hu Andrew J.Greenshaw Russell Greiner Tao Li | 2018 | Neuroscience Bulletin2018，34，2： | 6 |
| 9 | Markov repairable systems with stochastic regimes switching显示文摘Compared with the classical Markov repairable system,the Markov repairable system with stochastic regimes switching introduced in the paper provides a more realistic description of the practical system.The system can be used to model the dynamics of a repairable system whose performance regimes switch according to the external conditions.For example,to satisfy the demand variation that is typical for the power and communication systems and reduce the cost,these systems usually adjust their operating regimes.The transition rate matrices under distinct operating regimes are assumed to be different and the sojourn times in distinct regimes are governed by a finite state Markov chain.By using the theory of Markov process,Ion channel theory,and Laplace transforms,the up time of the system are studied.A numerical example is given to illustrate the obtained results.The effect of sojourn times in distinct regimes on the availability and the up time are also discussed in the numerical example. | Liying Wang Lirong Cui Mingli Yu | 2011 | Journal of Systems Engineering and Electronics2011，22，5： | 5 |
| 10 | High pulse energy fiber/solid-slab hybrid picosecond pulse system for material processing on polycrystalline diamonds显示文摘We demonstrate an all polarization-maintaining(PM) fiber mode-locked laser seeded, hybrid fiber/solid-slab picosecond pulse laser system which outputs 40 μJ, 10 ps pulses at the central wavelength of 1064 nm. The beam quality factors M2 in the unstable and stable directions are 1.35 and 1.31, respectively. 15 μJ picosecond pulses at the central wavelength of 355 nm are generated through third harmonic generation(THG) by using two Li B3 O5(LBO) crystals, in order to get better processing efficiency on polycrystalline diamonds. The high pulse energy and beam quality of these ultraviolet(UV) picosecond pulses are confirmed by latter experiments of material processing on polycrystalline diamonds. This scheme which combines the advantages of the all PM fiber mode-locked laser and the solid-slab amplifier enables compact, robust and chirped pulse amplification-free amplification with high power picosecond pulses. | Wei Chen Bowen Liu Youjian Song Lu Chai Qianjin Cui Qingjing Liu Chingyue Wang Minglie Hu | 2018 | High Power Laser Science and Engineering2018，6，2： | 5 |
| 11 | Comparison of viral RNA-host protein interactomes across pathogenic RNA viruses informs rapid antiviral drug discovery for SARS-CoV-2显示文摘In contrast to the extensive research about viral protein–host protein interactions that has revealed major insights about how RNA viruses engage with host cells during infection,few studies have examined interactions between host factors and viral RNAs(vRNAs).Here,we profiled vRNA–host protein interactomes for three RNA virus pathogens(SARS-CoV-2,Zika,and Ebola viruses)using ChIRP-MS.Comparative interactome analyses discovered both common and virus-specific host responses and vRNA-associated proteins that variously promote or restrict viral infection.In particular,SARS-CoV-2 binds and hijacks the host factor IGF2BP1 to stabilize vRNA and augment viral translation.Our interactome-informed drug repurposing efforts identified several FDA-approved drugs(e.g.,Cepharanthine)as broad-spectrum antivirals in cells and hACE2 transgenic mice.A co-treatment comprising Cepharanthine and Trifluoperazine was highly potent against the newly emerged SARS-CoV-2 B.1.351 variant.Thus,our study illustrates the scientific and medical discovery utility of adopting a comparative vRNA-host protein interactome perspective. | Shaojun Zhang Wenze Huang Lili Ren Xiaohui Ju Mingli Gong Jian Rao Lei Sun Pan Li Qiang Ding Jianwei Wang Qiangfeng Cliff Zhang | 2022 | Cell Research2022，32，1： | 5 |
| 12 | Age-Related Reduction in Cortical Thickness in First-Episode Treatment-Na?ve Patients with Schizophrenia显示文摘Substantial evidence supports the neurodevelopmental hypothesis of schizophrenia.Meanwhile,progressive neurodegenerative processes have also been reported,leading to the hypothesis that neurodegeneration is a characteristic component in the neuropathology of schizophrenia.However,a major challenge for the neurodegenerative hypothesis is that antipsychotic drugs used by patients have profound impact on brain structures.To clarify this potential confounding factor,we measured the cortical thickness across the whole brain using highresolution T1-weighted magnetic resonance imaging in 145 first-episode and treatment-naive patients with schizophrenia and 147 healthy controls.The results showed that,in the patient group,the frontal,temporal,parietal,and cingulate gyri displayed a significant age-related reduction of cortical thickness.In the control group,age-related cortical thickness reduction was mostly located in the frontal,temporal,and cingulate gyri,albeit to a lesser extent.Importantly,relative to healthy controls,patients exhibited a significantly smaller age-related cortical thickness in the anterior cingulate,inferior temporal,and insular gyri in the right hemisphere.These results provide evidence supporting the existence of neurodegenerative processes in schizophrenia and suggest that these processes already occur in the early stage of the illness. | Yin Lin Mingli Li Yi Zhou Wei Deng Xiaohong Ma Qiang Wang Wanjun Guo Yinfei Li Lijun Jiang Xun Hu Nanyin Zhang Tao Li | 2019 | Neuroscience Bulletin2019，35，4： | 5 |
| 13 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 14 | Numerical analysis of mode locking in multi-core photonic crystal fiber显示文摘With linearly coupled nonlinear Schrodinger equations,numerical analysis has been performed on the mode locking forming procedure of a fiber laser in the linear cavity configuration.The fiber is Yb-doped multi-core photonic crystal fiber and semiconductor saturable absorber mirror(SESAM) is adopted as the nonlinear transmission element to start mode locking.Because of the noise randomness,initial pulse would be picked out by SESAM in one or more cores which makes the multi-core mode locking quite different from single-core one.The two situations are compared and fully discussed.Mode locking in multi-core photonic crystal fiber laser can be realized only if the couple coefficient between the cores and the temporal overlap between the pulses in different cores are large enough. | FANG XiaoHui HU MingLie LI YanFeng CHAI Lu WANG QingYue | 2010 | Chinese Science Bulletin2010，55，18： | 4 |
| 15 | Oxidation and Thermal Shock Behavior of a Glass-Alumina Composite Coating on K38G Superalloy at 1000℃显示文摘The glass-alumina composite coatings were successfully prepared on the K38G superalloy substrates.Their isothermal oxidation and thermal shock behavior at 1000 ℃ were characterized.With a post-annealing process at 850 ℃,the composite coatings possessed an improved protective effect for the alloy substrates from isothermal oxidation and a higher resistance to thermal shock.Crystallization from the glass matrix and interfacial reaction between the matrix and alumina inclusions,which caused the composites more refractory and tough,accounted for this improvement.The micromechanisms for the formation of oxidation results of spinel ZnCr_2O_4 were also discussed. | Minghui Chen Mingli Shen Xin Wang Shenglong Zhu Fuhui Wang | 2012 | Journal of Materials Science & Technology2012，28，5： | 4 |
| 16 | Rett syndrome-causing mutations compromise MeCP2- mediated liquid—liquid phase separation of chromatin显示文摘Rett syndrome(RTT),a severe postnatal neurodevelopmental disorder,is caused by mutations in the X-linked gene encoding methyl-CpG-binding protein 2(MeCP2).MeCP2 is a chromatin organizer regulating gene expression.RTT-causing mutations have been shown to affect this function.However,the mechanism by which MeCP2 organizes chromatin is unclear.In this study,we found that MeCP2 can induce compaction and liquid-liquid phase separation of nudeosomal arrays in vitro,and DNA methylation further enhances formation of chromatin condensates by MeCP2.Interestingly,RTT-causing mutations compromise MeCP2-mediated chromatin phase separation,while benign variants have little effect on this process.Moreover,MeCP2 competes with linker histone H1 to form mutually exclusive chromatin condensates in vitro and distinct heterochromatin foci in vivo.RTT-causing mutations reduce or even abolish the ability of MeCP2 to compete with histone H1 and to form chromatin condensates.Together,our results identify a novel mechanism by which phase separation underlies MeCP2-mediated heterochromatin formation and reveal the potential link between this process and the pathology of RTT. | Liang Wang Mingli Hu Mei-Qing Zuo Jicheng Zhao Di Wu Li Huang Yongxin Wen Yunfan Li Ping Chen Xinhua Bao Meng-Qiu Dong Guohong Li Pilong Li | 2020 | Cell Research2020，30，5： | 3 |
| 17 | Selective Introduction of Carbazole and Diphenylamine into Spirofluorenexanthene Core for Different Phosphorescent Hosts显示文摘Built on the spiro[fluorene-9,9'-xanthene] (SFX) core and two frequently-used hole-transporting groups such ascarbazole and diphenylamine, two SFX derivatives, namely SFXCz and SFXDPA, have been synthesized byone-step reaction for red, green and blue phosphorescent organic light-emitting devices (PHOLEDs). Though theproperties of these two groups are very similar, the devices based on SFXCz and SFXDPA exhibit distinct perfor-mances. In blue PHOLEDs, the device based on SFXCz exhibited much better performances than that based onSFXDPA. However, the latter was superior to the former in green and red PHOLEDs. And the red PHOLED basedon SFXDPA exhibited maximum current efficiency (CE) of 27.1 cdoA^-l, power efficiency (PE) of 25.01m·W^-1, andexternal quantum efficiency (EQE) of 15.0%. The results show that the introduction of diphenylamine group issuitable for constructing green and red host materials, whereas the introduction of carbazole group is suitable forconstructing blue host materials. | Mingli Sun Shouzhen Yue Hongtao Cao Changjin Ou Yan Qian Ting Wang Ligang Chen Yi Zhao Wei Huang | 2016 | Chinese Journal of Chemistry2016，34，8： | 3 |
| 18 | Effects of repetitive transcranial magnetic stimulation on hypothalamic-pituitary-adrenal axis of patients with depression显示文摘Objective: To investigate the effects of sleep electroencephalogram-modulated repetitive transcranial magnetic stimulation (SEM-rTMS) and conventional rTMS (C-rTMS) on the activity of hypothalamic-pituitary-adrenal (HPA) axis in patients with depression. Methods: In a double-blind, randomized controlled trial, 164 patients diagnosed with depression were randomized to treatment with SEM-rTMS (n=57), C-rTMS (n=55) or sham rTMS (n=52) for 30 min every day for 10 d. Before and after treatment plasma concentrations of adrenocorticotropic hormone (ACTH) and cortisol (CORT) were measured, and the 24-item Hamilton Depression Rating Scale (HAMD-24) was used for assessment. Results: The HAMD-24 scores and plasma ACTH and CORT concentrations of these depressive patients before treatment were significantly different from those of the normal control group (P<0.05). The HAMD-24 scores and plasma ACTH and CORT concentrations in the SEM-r TMS group and conventional rTMS group were decreased significantly (P<0.05). There was a significant positive correlation between the HAMD-24 scores and plasma ACTH (n=240, r=0.105, P=0.048) and CORT concentrations (n=240, r=0.126, P=0.023) in the patients with depression before and after treatment. Conclusion: The antidepressant effect of rTMS, including SEM-rTMS, may be related to its decreasing HPA axis activity. (This trail was registered.

| 19 | Dual functional AgNPs-M13 phage composite serves as antibacterial film and sensing probe for monitoring the corrosion of chromium-containing dental alloys显示文摘The preparation of silver nanoparticles(AgNPs)with microbe or plant tissues as bio-template offers green approach,while it suffers from low harvest and purification is needed.Herein,we propose a facile protocol for one-pot preparation of AgNPs using M13 phage as bio-template by simply mixing AgN03 solution with alkali M13 phage.In the obtained AgNPs-M13 phage composite,Cr(Ⅲ)selectively coordinates with the amino residues on phage surface and leads to the aggregation of AgNPs through the bridging of M13 phages.This makes it feasible for colorimetric sensing of Cr(Ⅲ)by measuring the absorbance ratio of AgNPs at 600 and 405 nm,which provides a LOD of 14 nmol/L.The composite also showed favorable bactericidal activity for both Gram-positive and Gram-negative bacteria,making it a promising candidate as antibacterial film in chromium-containing dental alloys and meanwhile serve as a sensing probe for monitoring the corrosion of the dental alloys. | Ting Yang Na Li Xiaoyan Wang Jian Zhai Bo Hu Mingli Chen Jianhua Wang | 2020 | Chinese Chemical Letters2020，31，1： | 2 |
| 20 | Study on the Optimal Composition of Chitosan/Nano-TiO_2 Composite Film and Its Application in the Preservation of Jinqiu Pear显示文摘Water permeability can be used as a parameter to evaluate the effects of chitosan / nano-TiO_2 composite film on the preservation of fruits and vegetables.In this study,using water permeability as the objective function,an L9( 3)3orthogonal experiment was conducted with addition amounts of chitosan,nano-TiO_2 and glycerin as three factors at three levels. According to the experimental results,when the percentages of chitosan,nano-TiO_2 and glycerin in chitosan / nano-TiO_2 composite film was 2%,0. 03% and 2. 5%,respectively( i. e.,there were 2. 0 g of chitosan,0. 03g of nano-TiO_2 and 2. 5g of glycerin per 100 g composite film solution),the water permeability of chitosan / nano-TiO_2 composite film reached the minimum. Chitosan / nano-TiO_2 composite film prepared with the optimal composition was used for preservation of Jinqiu pear. The water loss rate,respiratory intensity and good fruit rate of preserved Jinqiu pear were determined,which indicated that the prepared chitosan / nano-TiO_2 composite film exhibited good preservative effects. | Xiqin TAO Mingli WANG | 2015 | Agricultural Biotechnology2015，4，3： | 2 |
