Objective To perform a comparative research on nucleoside drug resistance mutation and genotypes of chronic hepa‐tits B virus in Shanghai and Lanzhou .Methods The serum samples(Shanghai ,194 cases) and (Lanzhou ,325 cases) were collected . The common 7 drug resistant mutation loci ,genotype B and C were detected by using the PCR‐LDR method .The obtained data were analyzed by using the SPSS17 .0 statistical software .Results (1) Genotype C was the main genotype in two areas (Shanghai 79 .3% ,Lanzhou 81 .4% ) .(2) The mutation rate in Shanghai was higher than that in Lanzhou with statistical difference (48 .9%vs .35 .3% ,P<0 .01) .Lamivudine resistance mutation was predominant in all the mutations of two areas ,accounting for 75 .7%(153/202 ;Shanghai 68/92 ,Lanzhou 85/110);the difference in lamivudine resisrtance mutation loci had statistical difference be‐tween the two areas ;while the adefovir resistance loci was dominated by rtA181T/V ,the area difference had no statistical signifi‐cance(P>0 .05) .(3) The drug resistance mutation had no correlation with genotype .The C genotype mutation rate in Shanghai was higher than that in Lanzhou ,the difference was statistically significant (49 .0% vs .35 .4% ,P<0 .05 ) .(4) 4 kinds of drug re‐sistance rate had no correlation with genotype .Conclusion The genotype distributions are similar in two areas ;Shanghai has a higher drug resistance rate than Lanzhou ;the drug resistance occurrence has no relation with drug resistance type and genotype .

Clopidogrel combinated with aspirin can significantly improve the prognosis of cardiovascular disease in patients with coronary heart disease undergoing PCI, but at the same time, which can increase the risk of cardiovascular hemorrhage. However, plus TCM can significantly improve the therapeutic effect, reduce symptoms of angina, reduce the adverse drug reaction to alleviate the suffering of the patients, in particular, which can reduce the dosage of medicine to improve the quality of life of patients, reduce the application time of using clopidogrel to reduce the financial burden of patients,then improve patient compliance. This review provided reference to combat PCI postoperative treatment using the combination of Chinese and western medicine methods.

One hundred and sixty non-diabetic patients with cerebral ischemia of primary onset were enrolled in the study. The patients were divided into impaired glucose tolerance (IGT) group and normal glucose tolerance (NGT) group according to the oral glucose tolerance test (OGTT). Carotid atherosclerosis and carotid artery stenosis were examined with vascular Doppler ultrasonic detection. The incidence rates of carotid atherosclerosis in IGT group and NGT group were 87. 5% (70/80)and 63.8% (51/80)respectively (χ2= 12.240,P <0.001);the incidence rates of carotid stenosis in IGT group and NGT group were 63.8% (51/80) and 47. 5 % (38/80), respectively(χ2 =4. 279, P =0. 039);the degree of carotid artery stenosis in IGT group was higher than that in NGT group(χ2= 21.95, P < 0. 01). The results indicate that IGT may be related to atherosclerosis and stenosis of carotid artery in cerebral ischemic patients.

Objective To systematically evaluate the relationship between stroke location and post-stroke depression (PSD) in first-ever stroke patients.Methods The studies on the relationship between stroke location and PSD published from January 1980 to March 2016 were retrieved from databases,including Chinese science and technology journal full-text database (VIP),China journal full-text database (CNKI),Wanfan database,PubMed,ISI Web of Science,Ovid database and Elsevier Science Direct.RevMan5.3 software was adopted for data consolidation and analysis.Results A total of 14 studies,including 1 952 cases of patients were included.The meta analysis indicated that no direct relationship was found between stroke location and PSD in first-ever stroke patients [random effects model,95 ％CI(0.89,1.43),P＜0.01].The results of subgroup analysis indicated that the PSD was associated with the right hemisphere lesion when the Hamilton Depression Scale (HAMD) was adopted for assessment [fixed effects model,95 ％ CI(1.21,1.76),P＜0.01],while the relationships were not found in the subgroup analysis of time course after stroke and the aphasia occurrence.Conclusion Stroke location may be not directly associated with PSD,further studies are needed to ascertain the relationship between stroke location and PSD.

Objective:To investigate the inhibitory effect of small interfering RNA-Yes-associated protein 1 (siRNA-YAP1) on epithelial-mesenchymal transition (EMT) in human lens epithelial cells (LECs) induced by transforming growth factor-β 2 (TGF-β 2). Methods:Human LECs line (HLEB-3) was cultured and divided into normal control group and TGF-β 2 induced group.The cells in the normal control group were treated with serum-free low-glucose medium for 24 hours, and the cells in the TGF-β 2 induced group were treated with additional 10 ng/ml TGF-β 2 for 24 hours.The cultured HLEB-3 cells were divided into siRNA empty vector group, siRNA-YAP1 transfection group, siRNA empty vector+ TGF-β 2 group and siRNA-YAP1+ TGF-β 2 group, and the cells were transfected with plasmid including siRNA empty vector or siRNA-YAP1 sequence according to grouping.The relative expression levels of YAP1 mRNA and protein in various groups were detected and compared by quantitative real-time polymerase chain reaction (PCR), immunofluorescence and Western blot assay, respectively.The relative expression levels of EMT marker proteins (E-cadherin and Vimentin proteins) in various groups were detected by immunofluorescence and Western blot assay. Results:Compared with the normal control group, the expression level of E-cadherin protein was decreased (1.180±0.118 vs.0.830±0.104) and the Vimentin protein was increased (0.797±0.110 vs.1.240±0.110) in the TGF-β 2 induced group, with significant differences between the two groups ( t=3.857, P=0.018; t=-4.933, P=0.008).The relative expression levels of YAP1 mRNA and protein in the TGF-β 2 induced group were significantly increased in comparison with the normal control group (2.200±0.193 vs.1.136±0.123; 1.203±0.121 vs.0.967±0.025), with significant differences between the two groups ( t=-9.288, P<0.01; t=-3.329, P=0.029).Compared with the siRNA empty vector group, the expression levels of YAP1 mRNA and protein in the siRNA-YAP1 transfection group were significantly reduced (both at P<0.01).Compared with the siRNA empty vector+ TGF-β 2 group, the relative expression level of E-cadherin protein was significantly enhanced and the expression level of Vimentin protein was significantly reduced in the siRNA-YAP1+ TGF-β 2 group (both at P<0.01). Conclusions:YAP1 participates in the TGF-β 2 induced EMT in human LECs, and siRNA-YAP1 can suppress the EMT process.

BACKGROUND: In recent years, ultrasound microbubble gene transfer system has been applied for gene transfection in many parts of the body, but it has been seldom reported to be used for gene transfection in bone parts. OBJECTIVE: To investigate the efficiency and feasibility of ultrasound-targeted microbubble destruction applied for transfection of enhanced green fluorescent protein plasmid into the femoral head of rabbits.METHODS: Japanese big-ear rabbits were randomly divided into five groups: bare transfection, pre-irradiation + bare transfection, ultrasound transfection, pre-irradiation+ultrasound transfection, and repeatable transfection. In the first two groups, ultrasound-targeted gene transfection and irradiation was not used, but in the latter three groups, ultrasound-targeted microbubble destruction was used to transfect enhanced green fluorescent protein (EGFP) plasmid into the femoral head of rabbits. At 1 week after transfection, EGFP expression in femoral head was observed under the fluorescence microscope. RESULTS AND CONCLUSION: EGFP expression appeared in the ultrasound transfection, pre-irradiation + ultrasound transfection and repeatable transfection. The transfection efficiency of EGFP plasmid was significantly higher in the repeatable transfection group than in the other groups (P < 0.01). Obvious injury loci were not observed in the soft tissue and bone tissue slices of ultrasonic irradiation parts in the ultrasound transfection, pre-irradiation + ultrasound transfection and repeatable transfection groups. These results confirm that ultrasound-targeted microbubble destruction is a safe and effective method to transfect EGFP plasmid into the femoral head of rabbits.

Methods On the base of previous qualitative interview and literature review, Delphi consultation was performed to identify items of the Symptom Distress Scale for postoperative patients with pituitary tumor. By convenience sampling method, totally 191 patients from four first-class ternary hospitals in Jiangsu province were investigated effectively by this scale. Results A scale of 4 factors and 16 items was identified by expert interviews, item analysis, exploratory factor analysis and the four factors could explain 69.812%of the variance. The Cronbachαcoefficient of the scale was 0.920, the content validity index was 0.915, and the interrater reliability was 0.860. Conclusions Symptom Distress Scale for postoperative patients with pituitary tumor has good reliability and validity to assess the symptom distress of pituitary tumor patients after operation.

Objective To investigate the status and influencing factors of cooperation of doctors and nurses in the nutritional support of critically ill patients, and provide the basis for future improve the physician-nurse collaboration in the nutritional support. Methods Doctors and nurses who from ICU in Soochow were investigated by the Nurse-Physician Collaboration Scale (NPCS). Results The doctors′score of physician-nurse collaboration in the nutritional support of critically ill patients was 87.42 ±15.73, which was significantly higher than 80.97 ± 13.80 the nurses′(t=3.279, P= 0.001).In addition, under the item 1, 3, 5 in the dimension one as well as the total items in the dimensions two and three, the doctors′score was similarly higher than the nurses, and the differences are also statistically significant (Z=-3.894--1.964, all P<0.01 or 0.05). Technical titles, educational level and age was significantly related to the cooperative level between doctors and nurses respectively (χ2=11.037, P=0.012;F=3.488, P=0.037; F=3.499, P=0.016). Conclusions Doctors have higher levels of perceived collaboration than nurses in the nutritional support of critically ill patients, while both require further improvement. We should highlight the physician-nurse collaboration in feeding critically ill patients, and should improve the nutrition quality through standardized process management and active team cooperation.

Objective:To investigate the clinical characteristics and treatment of the abdominal cocoon.Mehods:The clinical data of 28 patients with abdominal cocoon from Jan 2004 to Dec 2018 were analyzed retrospectively.Results:Intestinal obstruction was the main clinical manifestations (25 cases), recurrent chronic ileus(17 cases) and abdominal mass (7 cases). Preoperative imaging examination showed varying degrees of intestinal obstruction. CT or MRI scan displayed that small intestinal loops were disorganized , clustered and encased in a thickened capsule. All the cases underwent operations, showing that small bowel were encapsulated in a dense gray-white fibrous membrane. Adhesiolysis and fibrous membrane excision were done with segmental enterectomy when it was necessary. Early postoperative intestinal obstruction occured in 6 cases, all were cured by conservative treatment.Conclusions:The combination of clinical symptoms and CT or MRI may facilitate in preoperative diagnosis. Abdominal cocoon is putative diagnosis when recurrent intestinal obstruction with abdominal mass. Surgery is the therapy of choice.
