1A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161

6Clinical and experimental study on regional administration of phosphorus32 glassmicrospheres in treating hepatic carcinoma显示文摘AIM To study the therapeutical effectiveness, dosage range and toxic adverse effects of domestic phosphorus 32 glass microsphere and evaluate its clinical significance. METHODS Ⅰ. Fifty two BALB/*!c tumor bearing male nude mice were allocated into treatment group( n =38) and control group( n =14). In the former group different doses of 32 P GMS were injected into the tumor mass, while in the latter 31 P GMS or no treatment was given. The experimental animals were sacrificed in batches, and then the tumors and their nearby tissues were examined by light and electron microscopy. Ⅱ. Through selective catheterization of hepatic artery, 32 P GMS was infused to 5 healthy domestic pigs in a dosage equivalent to the therapeutic dose for human being, and 31 P GMS was infused to another 5 healthy domestic pigs. Two pigs infused with contrast medium served as whole course blank controls. One pig from each group was surrendered to euthanasia at week 1, 4, 8 and 16 respectively. The ultrastructural histopath ological changes in liver tissues taken from different sites were evaluated semiquan titatively. Ⅲ. One hundred and twenty seven times of 32 P GMS intrahepatic artery interventional therapies were performed on 93 patients with hepatic carcinoma, including 79 cases of primary hepatic carcinoma and 14 cases of secondary hepatic carcinoma. 32 P GMS ( n =30), and group B, 32 P GMS and half dose of trans hepatic artery embolization (TAE) ( n =49) , and 18 patients with HCC by TAE only as control group C. Fourteen patients with secondary hepatic carcinoma were treated in the same way as group B or C. RESULTS Ⅰ. Comparing with the control group, the treatment group of tumor bearing nude mice attained the tumor inhibition rates of 59 7%-93 7% ( F =579 62, P <0 01) at 14*!d . At an absorbed dose of 7320Gy, the tumor cells were completely destroyed. When the absorbed doses ranged from 1830Gy to 3660Gy, most of the tumor cells showed the evidences of injury or necrosis, but there appeared some well differentiated tumor cells and enhanced effect of the autoimmunocytes. At an absorbed dose of 366Gy or less, some tumor cells still remained active proliferative ability. The definite anticancer effect appeared as early as 3d after intratumoral injection of 32 P GMS. Ⅱ. The cumulative amount of 32 P GMS in the target tissue after trans hepatic artery instillation attained more than 90% of the total dose administrated. Semiquantitative analysis of ultrastructral morphology in the experimental group showed no statistical difference between the nuclear abnormality (N abn ) and mitochondrial variability (M var ) at week 1 or 2, but revealed prominent difference (χ 2=6 70-9 68, P <0 01 , χ 2=65 09-115 09, P <0 001 ) as compared with those in the other groups. In the experimental group the N abn in tissues showed no significant difference between week 8 and week 16. No apparent changes were found in the stomach, spleen, kidney and lung tissues of the experimental pigs. Ⅲ. The therapeutical results of HCC patients in group A were closely approximated to those of group C, no hematological toxic side effects were noted, and the systemic reaction was mild. In some patients 2*!mos - 3*!mos after treatment some secondary foci appeared around the periphery of the primary lesion. In general better effectiveness was obtained in patients with small lesion. After analyzing by RIDIT method, the therapeutic result in group B was significantly better than that in group C, and secondary foci around the original lesion were rarely seen at 3*!mos after treatment. In group C the collateral circulation was reestablished along the periphery of primary foci and the secondary foci appeared more frequently, and required to undergo several courses of treatment. In group B, 4 cases of HCC were treated surgically as their mass decreased in size after 32 P GMS treatment.LIU Lu, JIANG Zao, TENG Gao Jun, SONG Ji Zhi, ZHANG Dong Sheng, GUO Qing Ming, FANG Wen, HE Shi Cheng and GUO Jin He 1999World Journal of Gastroenterology1999,5,6:21
7Study on Relationship between Microstructure of Active Phase and HDS Performance of Sulfided Ni-Mo Catalysts: Effect of Metal Loading显示文摘Six Ni-Mo catalysts with different metal contents were prepared and characterized by N2 adsorption and X-ray diffractometry. The active phase microstructure of these catalysts was examined by the Raman spectroscopy, temperatureprogrammed reduction(TPR), X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. Hydrodesulfurization(HDS) activity of catalyst samples were analyzed in a flow fixed-bed microreactor. The sulfidation degree of Mo and the length of the MoS2 slab slightly increased with the amount of metal loaded following sulfidation. This small change is attributed to polymolybdate species observed in all the oxidized catalysts. Weak metal-support interactions, as determined by the TPR technique, increased the NiSx sulfidation phase and MoS2 slab stacking. The HDS activity of the catalyst samples increased with the number of active sites. For high metal loading catalysts, their HDS activity was nearly identical because the sulfur atoms cannot easily approach active sites. This change is caused by the large number of stacked layers in the MoS2 slabs as well as the decrease in the specific surface area and pore volume of the catalyst samples with an increasing metal loading.Guo Rong Shen Benxian Fang Xiangchen Sun Jin Peng Chong Cui Xiaoli 2014China Petroleum Processing & Petrochemical Technology2014,16,2:21
8SIMULATION OF FLUID-SOLID INTERACTION ON WATER DITCHING OF AN AIRPLANE BY ALE METHOD显示文摘Ditching is considered as one of the important aspects of safety performances of airplanes.It is related primarily with the fluid-solid interaction,whose studies mainly depend on experiments at the present time.Numerical and analytical methods for fluid-solid interaction by using 3-D full scale airplane's model will reduce the dependence on the expensive model tests.Numerical studies can be used to estimate the safety of ditching and provide a reference for the crashworthiness design.This article proposes a 3-D dynamical structural model after the real shape of an airplane and an Arbitrary Lagrange-Euler (ALE) fluid-field model,to simulate the fluid-solid interactions caused by low speed ditching.The simulation is based on interaction computational methods,within LS-DYNA nonlinear finite-element code.The results of pressure distributions and accelerating time histories of the airplane's subfloor are discussed in the context of the safety of ditching,and the simulation results and the analytical methods are verified.HUA Cheng FANG Chao CHENG Jin 2011Journal of Hydrodynamics2011,23,5:20
9Sex-influenced association of non-alcoholic fatty liver disease with colorectal adenomatous and hyperplastic polyps显示文摘AIM To investigate the relationship between non-alcoholic fatty liver disease(NAFLD) and colorectal adenomatous and hyperplastic polyps.METHODS A retrospective cross-sectional study was conducted on 3686 individuals undergoing health checkups(2430 males and 1256 females). All subjects underwent laboratory testing,abdominal ultrasonography,colonoscopy,and an interview to ascertain the baseline characteristics and general state of health. Multinomial logistic regression analysis was performed to examine the association between NAFLD and the prevalence of colorectal adenomatous and hyperplastic polyps.Furthermore,the relationship was analyzed in different sex groups. Subgroup analysis was performed based on number,size,and location of colorectal polyps.RESULTS The prevalence of colorectal polyps was 38.8% in males(16.2% for adenomatous polyps and 9.8% for hyperplastic polyps) and 19.3% in females(8.4% for adenomatous polyps and 3.9% for hyperplastic polyps). When adjusting for confounding variables,NAFLD was significantly associated with the prevalence of adenomatous polyps(OR = 1.28,95%CI: 1.05-1.51,P < 0.05) and hyperplastic polyps(OR = 1.35,95%CI: 1.01-1.82,P < 0.05). However,upon analyzing adenomatous and hyperplastic polyps in different sex groups,the significant association remained in males(OR = 1.53,95%CI: 1.18-2.00,P < 0.05; OR = 1.42,95%CI: 1.04-1.95,P < 0.05) but not in females(OR = 0.44,95%CI: 0.18-1.04,P > 0.05; OR = 1.18,95%CI: 0.50-2.78,P > 0.05). CONCLUSION NAFLD is specifically associated with an increased risk of colorectal adenomatous and hyperplastic polyps in men. However,NAFLD may not be a significant factor in the prevalence of colorectal polyps in women.Qin-Fen Chen Xiao-Dong Zhou Yang-Jie Sun Dan-Hong Fang Qian Zhao Jun-Hua Huang Yin Jin Jian-Sheng Wu 2017World Journal of Gastroenterology2017,23,28:19

11Changes in vitreous VEGF, bFGF and fibrosis in proliferative diabetic retinopathy after intravitreal bevacizumab显示文摘AIM: To evaluate the relationship between intravitreal bevacizumab(IVB) treatment and the levels of vitreous vascular endothelial growth factor(VEGF), basic fibroblast growth factor(b FGF) and vitreous-retina surface fibrosis in patients with proliferative diabetic retinopathy(PDR).·METHODS: This study was a prospective, open-label,controlled, randomized clinical trial. Sixty-eight eyes of PDR patients(n =53) and macular hole patients(n =15)were enrolled in this study. Thirty-four eyes of the PDR patients received IVB before vitrectomy. Twenty-three of the 34 PDR patients received IVB treatment 5d before vitrectomy(subgroup a), and 11 of the 34 PDR patients received IVB treatment greater than 2wk prior to vitrectomy(subgroup b). Nineteen of the PDR patients did not receive IVB treatment at any time prior to vitrectomy. The levels of b FGF and VEGF in vitreous samples were measured using enzyme-linked immunosorbent assay(ELISA) and the degree of vitreoretinal fibrosis was characterized using clinical data and data obtained intra-operatively.·RESULTS: In PDR patients, VEGF and b FGF levels were significantly increased compared to non-PDR(control) subject's eyes(P <0.01). In PDR patients,vitreous VEGF levels were significantly decreased following IVB treatment compared to PDR patients that did not receive IVB treatment(P <0.01). The degree of vitreoretinal fibrosis was significantly increased in subgroup b compared to subgroup a(P <0.05) and to patients that did not receive IVB(P <0.05). Vitreous b FGF levels were significantly greater in subgroup b than subgroup a(P <0.01) or in patients who did not receive IVB treatment(P <0.05). A Spearman's rank correlationtest indicated that higher levels of vitreous b FGF, but not VEGF, correlated with the degree of vitreoretinal fibrosis.·CONCLUSION: We found that b FGF levels increase in PDR patient's vitreous after IVB treatment longer than two weeks prior to vitrectomy and correlated with the degree of fibrosis after IVB treatment. These findings suggest vitreous fibrosis is increased in PDR patients after IVB treatment may be due to increased levels of b FGF.Jiu-Ke Li Fang Wei Xiao-Hong Jin Yuan-Min Dai Hu-Shan Cui Yu-Min Li 2015International Journal of Ophthalmology(English edition)2015,8,6:19

17Long noncoding RNA RP4 functions as a competing endogenous RNA through miR-7-5p sponge activity in colorectal cancer显示文摘AIM To investigate the role of long noncoding RNA(lnc RNA) RP4 in colorectal cancer.METHODS Lentivirus-mediated lnc RNA RP4 overexpression and knockdown were performed in the colorectal cancer cell line SW480. Cell proliferation, tumor growth, and early apoptosis were evaluated by a cell counting kit-8 assay, an in vivo xenograft tumor model, and annexin V/propidium iodide staining, respectively. Analysis of the lnc RNA RP4 mechanism involved assessment of the association of its expression with mi R-7-5 p and the SH3 GLB1 gene. Western blot analysis was also performed to assess the effect of lnc RNA RP4 on the autophagy-mediated cell death pathway and phosphatidylinositol-3-kinase(PI3 K)/Akt signaling.RESULTS Cell proliferation, tumor growth, and early apoptosis in SW480 cells were negatively regulated by lnc RNA RP4. Functional experiments indicated that lnc RNA RP4 directly upregulated SH3 GLB1 expression by acting as a competing endogenous RNA(ce RNA) for mi R-7-5 p. This interaction led to activation of the autophagy-mediated cell death pathway and de-repression of PI3 K and Akt phosphorylation in colorectal cancer cells in vivo.CONCLUSION Our results demonstrated that lnc RNA RP4 is a ce RNA that plays an important role in the pathogenesis of colorectal cancer, and could be a potential therapeutic target for colorectal cancer treatment.Mu-Lin Liu Qiao Zhang Xiao Yuan Long Jin Li-Li Wang Tao-Tao Fang Wen-Bin Wang 2018World Journal of Gastroenterology2018,24,9:16
