| 1 | Association of cancer prevention awareness with esophageal cancer screening participation rates: Results from a population-based cancer screening program in rural China显示文摘Objective: : China have implemented population-based esophageal cancer(EC) screening programs, however,the participant rates were relatively low. This study was conducted to examine the association between cancer prevention knowledge and EC screening participation rates(PRs).Methods: : Data in the analyses were obtained from a population-based cancer screening program in four provinces in China since 2007. In the course of 2007-2016, participants who were evaluated as high risk for EC and subsequently recommended for endoscopy examination were included in the final analysis. One-way analysis of variance test, Chi-square test and logistic regression analysis were applied.Results: : A total of 28,543 individuals assessed as high-risk population for EC were included in this study, with13,036 males(45.67%) and 15,507 females(54.33%). The prevalence rates of current smoking and alcohol drinking were higher in males(58.25% and 44.22%, respectively) than in females(5.35% and 4.05%, respectively).Participants of females, and those who had older age, lower income, as well as higher education level and cancer prevention knowledge level were more likely to undergo endoscopy. Multivariable analysis showed that higher cancer prevention knowledge was associated with higher PR for endoscopic screening [adjusted odd ratio(aORQ4/Q1) =1.511, 95% confidence interval(95% CI): 1.398-1.632] among our study subjects. This association between cancer prevention knowledge and compliance with endoscopic screening also tends to be strong within subgroups of males, females, aged below 60 years, aged 60 years and above, and lower level of education(illiterate individuals and those with junior high education or less).Conclusions: : Our results displayed a positive relationship between cancer prevention knowledge and PRs for endoscopic screening, implying cancer prevention awareness being an independent influence factor for compliance with EC screening. Promoting public campaigns about comprehensive knowledge of cancer prevention seemed to be a reasonable and effective strategy to improve population PRs for EC screening. | Shangchun Jia He Li Hongmei Zeng Rongshou Zheng Jiang Li Jufang Shi Zhixun Yang Maomao Cao Wanqing Chen | 2019 | Chinese Journal of Cancer Research2019，31，4： | 10 |
| 2 | Effect of low-frequency pulse percutaneous electric stimulation on peripheral nerve injuries at different sites显示文摘BACKGROUND: The postoperative recovery of nerve function in patients with peripheral nerve injury is always an important problem to solve after treatment. The electric stimulation induced electromagnetic field can nourish nerve, postpone muscular atrophy, and help the postoperative neuromuscular function. OBJECTIVE: To observe the effects of low-frequency pulse percutaneous electric stimulation on the functional recovery of postoperative patients with peripheral nerve injury, and quantitatively evaluate the results of electromyogram (EMG) examination before and after treatment. DESIGN: A retrospective case analysis. SETTING: The Sixth People’s Hospital affiliated to Shanghai Jiaotong University. PARTICIPANTS: Nineteen postoperative inpatients with peripheral nerve injury were selected from the Department of Orthopaedics, the Sixth People’s Hospital affiliated to Shanghai Jiaotong University from June 2005 to January 2006, including 13 males and 6 females aged 24-62 years with an average of 36 years old. There were 3 cases of brachial plexus nerve injury, 3 of median nerve injury, 7 of radial nerve injury, 3 of ulnar nerve injury and 3 of common peroneal nerve injury, and all the patients received probing nerve fiber restoration. Their main preoperative manifestations were dennervation, pain in limbs, motor and sensory disturbances. All the 19 patients were informed with the therapeutic program and items for evaluation. METHODS: ① Low-frequency pulse percutaneous electric stimulation apparatus: The patients were given electric stimulation with the TERESA cantata instrument (TERESA-0, Shanghai Teresa Health Technology, Co.,Ltd.). The patients were stimulated with symmetric square waves of 1-111 Hz, and the intensity was 1.2-5.0 mA, and it was gradually adjusted according to the recovered conditions of neural regeneration following the principle that the intensity was strong enough and the patients felt no obvious upset. They were treated for 4-24 weeks, 10-30 minutes for each time, 1-3 times a day, and 6 weeks as a course. ② EMG examination was applied to evaluate the recoveries of recruitment, motor conduction velocity (MCV) and sensory conduction velocity (SCV) before and after treatment. The patients were examined with the EMG apparatus (DISA2000C, Danmark) before and after the treatment of percutaneous electric stimulation. ③ Standards for evaluating the effects included cured (complete recovery of motor functions, muscle strength of grade 5, no abnormality in EMG examination), obviously effective [general recovery of motor function, muscle strength of grade 4, no or a few denervation potentials, motor conduction velocity (MCV) and sensory conduction velocity (SCV)], improved (partial recovery of motor function, muscle strength of grade 3, denervation potentials and reinneration potentials, slowed MCV and SCV, invalid (no obvious changes of motor function). MAIN OUTCOME MEASURES: ① Ameliorated degree of the nerve function of the postoperative patients with peripheral nerve injury treated with percutaneous electric stimulation; ② Changes of EMG examination before and after treatment. RESULTS: All the 19 postoperative patients with peripheral nerve injury were involved in the analysis of results. ① Comparison of nerve function before and after treatment in 19 patients with peripheral nerve injury of different sites: For the patients with radial nerve injury (n=7), the nerve functions all completely recovered after 8-week treatment, and the cured and obvious rate was 100% (7/7); For the patients with brachial plexus nerve injury (n=3), 1 case had no obvious improvement, and the cured and obvious rate was 67% (2/3); For the patients with common peroneal nerve injury (n=3), the extension of foot dorsum generally recovered in 1 case of nerve contusion after 4-week treatment, and the cured and obvious rate was 67% (2/3); For the patients with median nerve injury (n=3), muscle strength was obviously recovered, and the cured and obvious rate was 100% (3/3); For the patients with ulnar nerve injury (n=3), 1 case only had recovery of partial senses, and the cured and obvious rate was 67% (2/3). Totally 9 cases were cured, 7 were obviously effective, 1 was improved, and only 2 were invalid. After 4 courses, the cured rate of damaged nerve function after four courses was 47% (9/19), and effective rate was 89% (17/19). ② Comparison of EMG examination before and after treatment: Before and after percutaneous electric stimulation, he effective rates of recruitment, MCV and SCV were 89% (17/19), 58% (11/19), 47% (9/19) respectively, and there were extremely obvious differences (P < 0.01). CONCLUSION: ① Low-frequency pulse percutaneous electric stimulation can improve the nerve function of postoperative patients with peripheral nerve injury of different sites, especially that the injuries of radial nerve and median nerve recover more obviously. ②Percutaneous electric stimulation can ameliorate the indexes of EMG examination, especially the recruitment, in postoperative patients with peripheral nerve injury. | Jinwu Wang Liye Chen Qi Li Weifeng Ni Min Zhang Shangchun Guo Bingfang Zeng | 2006 | Neural Regeneration Research2006，1，3： | 1 |

| 5 | Differential diagnosis of cervical nerve compression syndrome of the external intervertebral foramen显示文摘The aim of the present research is to study the mechanism of cervical nerve compression syndrome of the external intervertebral foramen and its differential diagnosis with cervical spondylosis.Diagnostic treatment with muscle relaxant,vasodilator,neurotrophic medicine and celecoxib(COX)-2 inhibitor were performed in 20 patients with cervical nerve compression syndrome of the external intervertebral foramen and 20 patients with cervical spondylosis confirmed by operation.Diagnostic local block therapy was performed additionally in cases showing little effect after diagnostic treatment.All the patients were followed up postoperatively for more than one year.Fifteen cases with cervical nerve compression syndrome of the external intervertebral foramen were healed by the diagnostic treatment.The other five cases had a short-term remission and there was no recurrence after diagnostic local block therapy.Diagnostic treatment led to short-term alleviation of the symptom in 20 cases with cervical spondylosis confirmed by operation,the results of which was far from satisfactory and operation was undertaken finally in all the 20 cases.The etiology of cervical nerve compression syndrome of the external intervertebral foramen lies in the compression of the cervical plexus,brachial plexus and cervical dorsal rami by the tendinous decussating fibers of the scalenus anticus,medius,minimus and the posterior muscles of the neck.Diagnostic treatment was propitious to differentiate cervical nerve compression syndrome of the external intervertebral foramen from cervical spondylosis. | WANG Jinwu NI Weifeng LI Qi XU Jianguang ZHU Haibo ZHAO Binghui GUO Shangchun ZENG Bingfang | 2007 | Frontiers of Medicine2007，1，2： | 1 |

| 7 | An isolation strategy to anchor atomic Ni or Co cocatalysts on TiO_(2)(A)for photocatalytic hydrogen production显示文摘TiO_(2) has been considered as an ideal photocatalyst for water splitting.However,narrow light absorbance,low charge separation efficiency,and rare surface active sites lead to the low photocatalytic efficiency of TiO_(2).Although extensive research attempted to improve the situation,there is still lack of method for constructing high active and noble-metal-free TiO_(2) photocatalyst for H_(2) evolution reactions(HER).In this work,we loaded single atomic(SA)Ni(or Co)on the surface of anatase TiO_(2)(TiO_(2)(A))nanosheets by an isolation strategy.Ethylene diamine tetraacetic acid and ethylene glycol(EDTA-EG)compounds were used to chelate metal ions in solution and form carbon quantum dots in the following thermal treatment to isolate the metal ions on surface of TiO_(2)(A).The prepared Ni SA/TiO_(2)(A)catalyst owned a“skin wrapped body”structure with in-situ formed twodimensional(2D)heterojunction facilitating the fast electron transfer.As a result,the Ni SA/TiO_(2)(A)catalyst showed a high H_(2) evolution rate of 2,900μmol·g−1·h−1.This work provides an isolation strategy for constructing promising single-atom metal catalyst for photocatalysis and beyond. | Shangchun Lv Mengxi Pei Yuxiang Liu Zhichun Si Xiaodong Wu Rui Ran Duan Weng Feiyu Kang | 2022 | Nano Research2022，15，7： | 0 |
| 8 | Establishment of an animal model of extra-vertebral foramen cervical nerve entrapment by local electrical stimulation and selection of suitable stimulation parameters显示文摘A rat model of extra-vertebral foramen cervical nerve entrapment was established according to the following parameters:stimulation intensity 20 V;frequency 50 Hz;pulse width 200 μs;duration 333 ms/s for a total of 8 hours.After the electrical stimulation,rats exhibited mild muscle fiber atrophy,mild inflammatory exudates,connective tissue local fibrosis and chondrocyte metaplasia.Mean muscle fiber cross-sectional area was reduced.The nerve myelin sheath continuity was partially demyelinated.The microstructure of nerve cells was disrupted and these symptoms worsened with prolongation of the stimulation.The shoulder,neck and upper extremity muscles on the tested side demonstrated positive sharp waves and fibrillations.The severity increased with continuation of the stimulation.High amplitude and polyphasic motor unit potentials gradually appeared.Similar findings were seen in the contralateral side,but at a less severe level. | Jinwu Wang Juliet Hou Qi Li Jian Tang Biyu Rui Shangchun Guo Haitao Jiang Cunyi Fan You Wang Zhenan Zhu Kerong Dai Guang H Yue | 2011 | Neural Regeneration Research2011，6，29： | 0 |
| 9 | MAVEN observation of magnetosonic waves in the Martian magnetotail region显示文摘Magnetosonic waves are an important medium for energy transfer in collisionless space plasma.Magnetosonic waves have been widely investigated in the upstream of the bow shock at Mars.These waves are believed to originate from pickup ions or reflected particles.By utilizing MAVEN spacecraft data,we have observed the occurrence of quasi-perpendicularly propagating magnetosonic emissions near the proton gyrofrequency in the Martian magnetotail region.These plasma waves are associated with a significant enhancement of proton and oxygen flux.The excited magnetosonic waves could possibly heat the protons through resonance and facilitate the ionospheric plasma escape.Our results could be helpful to better understand the Mars’magnetospheric dynamics and offer insights into possible energy redistribution between waves and plasma in the Martian nightside magnetosphere. | ShangChun Teng JiCheng Sun JiaWei Gao Y.Harada Markus Fraenz DeSheng Han | 2024 | Earth and Planetary Physics2024，8，2： | 0 |
| 10 | Equation of state of initially liquid carbon monoxide and nitrogen mixture显示文摘The modified liquid perturbation variational theory and the improved vdW-1f model were applied to calculating the equation of the state of liquid CO-N2 mixture with the ratio of 1:1, 4:1 and 1:4, respectively, in the shock pressure range of 9-49 GPa. It was shown that the calculated result for CO-N2 mixture with the ratio of 1:1 is well consistent with the earlier experimental data. The thermodynamics equilibrium, chemical equilibrium and phase equilibrium were all considered in detail. It was found that Hugoniot of liquid CO-N2 mixture is moderately softened in the pressure range of 20-30 GPa and 30-49 GPa for different initial proportions, and that the Hugoniot is more softened in the latter pressure range, which means that the structural phase transition occurs near 20 GPa and 30 GPa. Since the shock pro-ductions may absorb a plenty of systematic energy, the shock temperature and pressure decline compared with the case of no chemical reaction. Pressures and temperatures increase gradually with the increase in the mole fraction of nitrogen composition. The results for the 1:1 CO-N2 mixture lie in the middle of two others. Therefore, it was shown that the modified Lorentz-Berthelor rule used in the scheme is effective to study shock-compression properties of liquid CO-N2 mixture under high temperatures and high pressures. | YANG JinWen SUN Dong SUN Yue SHI ShangChun | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，6： | 0 |
| 11 | Effect of PMMA Removal Methods on Opto-Mechanical Behaviors of Optical Fiber Resonant Sensor With Graphene Diaphragm显示文摘Regarding the dependence of the treatment of removing polymethyl methacrylate(PMMA)from graphene upon the prestress in the film,two typical PMMA removal methods including acetone-vaporing and high-temperature annealing were investigated based on the opto-mechanical behaviors of the developed optical fiber Fabry-Perot(F-P)resonant sensor with a 125-pm diameter and~10-layer-thickness graphene diaphragm.The measured resonant responses showed that the F-P sensor via annealing process exhibited the resonant frequency of 481kHz and quality factor of 1034 at~2Pa and room temperature,which are respectively 2.5 times and 33 times larger than the acetone-treated sensor.Moreover,the former achieved a high sensitivity of 110.4kHz/kPa in the tested range of 2Pa-2.5kPa,apparently superior to the sensitivity of 16.2kHz/kPa obtained in the latter.However,the time drift of resonant frequency also mostly tended to occur in the annealed sensor,thereby shedding light on the opto-mechanical characteristics of graphene-based F-P resonant sensors,along with an optimized optical excitation and detection scheme. | Yujian LIU Cheng LI Shangchun FAN Xuefeng SONG | 2022 | Photonic Sensors2022，12，2： | 0 |
