In recent years,endoscopic technique has become a basic procedure for the diagnosis and treatment of biliary and pancreatic diseases,thus the procedure-related complications of ERCP and endoscopic sphincterotomy(EST) become prominent day by day. Post-EST bleeding is one of the most serious complications of the procedure,and its first line treatment involves a variety of endoscopic techniques,such as epinephrine or fibrin glue local injection,electric coagulation and heat probe,clamps and covered metal stents. If these are not successful,transcatheter arterial embolization or surgical operation should be considered. In this article,the above-mentioned treatment modalities of post-EST bleeding were reviewed.

Objective To analyse the effect of repaglinide combined with Zhenqi Jiangtang Capsules on βcell function in elderly patients with type 2 diabetes mellitus.Methods 60 elderly patients were collected from harbour branch of Hainan provincial People's hospital, who were diagnosed with type 2 diabetes mellitus .All patients were randomly divided into experimental group and control group, 30 cases in each group, 2 groups of patients were given control diet, moderate exercise, and other conventional adjuvant therapy.Control group was treated with repaglinide orally on the basis of routine adjuvant treatment, 1 mg/times, three times per day,experimental group were given Zhenqi Jiangtang Capsules based on the treatment in control group,4 grains/times,three times per day.Both groups were treated for 4 weeks, after the end of treatment, blood glucose levels,serum insulin levels,βcell function and serum lipids in all patients were detected.ResuIts After treatment, compared with control group, the levels of blood glucose, HbA1c and AUCg in experimental group were significantly lower ( P<0.05 );the insulin levels 30 min,60 min, 120 min after meal were significantly higher (P<0.05);the HOMA-IR of patients was significantly lower(P<0.05);IRG, AUCi and AUCi/AUCg were significantly higher (P<0.05);the serum TC, TG, LDL levels were significantly lower, serum HDL levels were significantly higher(P<0.05).ConcIusion Repaglinide combined with Zhenqi Jiangtang Capsules can significantly reduce the blood glucose and lipid levels in elderly patients with type 2 diabetes, improve the function of pancreatic beta cells, promote postprandial insulin secretion and improve insulin resistance.

In the paper, 32 lots of intravenous immunoglobulin (IVIG)were tested by an animal model,the hypotensive test of rats. A linear correlation was found between prekallikrein activator (PKA)activity and hypotensive reaction if the inflow of human IVIG was made rapid (r=0.96,n=23). The preliminary observations indicated that it would be satisfactory that the PKA activity was below 35IU/ ml and the size of reduction in blood pressure was not 15% higher than that of control animal's level.The rat model can provide a method for safe usage of the intravenous immunoglobulin and reliable detection of and control over the residual PKA activity in blood products.

Objective To observe critical patients with thrombocytopenia,and exam their coagulation function,so as to diagnose disseminated intravascular coagulation(DIC)in the early stage.Methods Totally 56 critical patients complicated with thrombocytopenia were enrolled in the investigation;complete set of DIC tests were performed.A total of 26 cases were diagnosed as DIC according to the criteria from the International Society of Thrombosis Haemostasis(ISTH).The sensitivity,specificity,accuracy,likelihood ratio,predictive value of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),fibrinogen(Fg),antithrombin Ⅲ and bleeding signs(including petechia and ecchymosia)were calculated by applying fourfold table.Results The specificity of PT prolongation and Fg reduction was 87.0%;the sensitivity of ATⅢ decrease,and each of PT prolongation,Fg reduction,and bleeding(including petechia and ecchymosis)were as high as 96.0%.Conclusion Multi-markers based on thrombocytopenia are likely to improve sensitivity and specificity of DIC diagnosis.

OBJECTIVE To observe the therapeutic effectiveness and safety of the indigenous teicoplanin in intensive care unit(ICU) patients with severe infections of Gram-positive(G+) cocci.METHODS Sixty patients with severe Gram-positive bacteria infection received teicoplanin which was produced by Xinchang Pharmaceutical Factory of Zhejiang Medicine Co,Ltd.by infusion for 7-14 d.Dosage was adjusted according to the creatinine clearance rate.Maximum temperature,APACHEⅡ score,indicators of inflammatory response,liver and kidney function,microbiologic examination and adverse reactions were observed before treatment and the end of 7-14 day treatment.RESULTS Seventy-two strains of Gram-positive cocci were isolated from 60 patients,in which meticillin-resistant Staphylococcus aureus(MRSA),meticillin-resistant S.epidermidis(MRSE),Enterococcus faecium,E.faecalis,S.haemolyticus and E.gallinarum accounted for 58.33%,8.33%,16.67%,5.56%,8.33% and 2.78%,respectively.After treatment,59 strains of Gram-positive cocci were eliminated while 13 strains were not eliminated and bacteriological eliminated rate(calculated by strains) was 86.1%;In this group,twenty-eight patients were cured while twenty-two cases were markedly improved.The total bacteriological eliminated rate was 81.94%.The incidence of adverse reactions was low and only a slight increase or decrease in platelet count was observed which didn′t require special treatment interventions.CONCLUSIONS Indigenous teicoplanin has certain therapeutic effectiveness and is safe for severe Gram-positive bacteria infected patients,particularly for septic patients with organ damage in ICU.In patients highly suspected with meticillin-resistant staphylococci or enterococci infection,teicoplanin may be a choice for initial empirical treatment.

This study is to explore the activation of the Ca2+/CaM/CaN signal pathway in 5-HT-induced proliferation of rat pulmonary artery smooth muscle cells (PASMCs) and the inhibitory effect of m-nisoldipine (m-Nis) on this pathway. PASMCs were cultured with the explant technique. The proliferation of PASMCs was evaluated by MTT assay. Confocal microscopy was used to measure the change of [Ca2+]i. The mRNA expression of CaM and CaN was evaluated by RT-PCR and the activity of CaN was measured according to the instruction of kits. The results of MTT assay suggested that 5-HT (1 micromol x L(-1)) significantly induced the proliferation of rat PASMCs (P < 0.01), which was inhibited obviously by m-Nis (P < 0.05 or P < 0.01). Similarly, m-Nis inhibited 5-HT-induced elevation of [Ca2+]i (P < 0.01). The mRNA expression of CaM, CaN and the activation of CaN were also inhibited by m-Nis at different degrees (P < 0.05 or P < 0.01). Thus, the results of this study suggested that Ca2+/CaM/CaN signal pathway played an important role in 5-HT-induced proliferation of rat PASMCs, the inhibition of m-Nis on proliferation of rat PASMCs may be related to the blockage of Ca2+/CaM/CaN signal pathway by inhibiting the elevation of [Ca2+]i.

Objective To explore a new type community nursing mode which can improve the life quality of community elderly population with depression tendency.Methods In the chosen community of Jilin City,we used Geriatric Depression Scale (GDS) to identify the elderly population with depression tendency.78 elderly people with depression tendency who met the conditions of study were assigned to the intervention group and the control group with 39 people in each group randomly.8-week group-intervention was given to the intervention group,and no intervention was given to the control group.For the intervention group,the total intervention time was 8 weeks,once a week for continuous 8 times together and intervention time was 90 minutes for each time.The Geriatric Depression Scale (GDS) and the world health organization quality of life (WHOQOL-BREF) were used to measure the quality of life of the two groups.Results After intervention,the total scores of the intervention group were significantly lower than those of the control group,the difference was statistically significant.Average scores of each dimension in the life quality of the intervention group were obviously higher than those of the control group.Conclusions Group intervention mode for the community elderly population with depression tendency was feasible,effective,and reasonable.It can be applied to mental health care of community elderly people,and can also provides basis for early discovery and early intervention of the community elderly people with depression.

Objective: To investigate the clustering of health-risk behaviors and its influencing factors among children and adolescents in Yancheng City, Jiangsu Province, so as to provide insights into the prevention and control of health-risk behaviors among children and adolescents. Methods: Students were randomly sampled from 4 primary schools, 4 junior high schools and 4 senior high schools in Yancheng City using a multi-stage stratified cluster random sampling method from September to December 2021. Students' demographics and 12 health-risk factors including unhealthy diet, insufficient physical activity and attempted smoking were collected using the Student's Health Status and Influencing Factors Questionnaire by Jiangsu Provincial Center for Disease Control and Prevention, and factors affecting the clustering of health-risk behaviors were identified using a multivariable linear regression model. Results: A total of 2 925 valid questionnaires were recovered, and the respondents included 1 611 boys (55.08%) and 1 314 girls (44.92%). A total of 2 896 respondents were detected with health-risk behaviors, with a detection rate of 99.09%, and 2 772 respondents were detected with clustering of health-risk behaviors (93.06%). Insufficient sleep, insufficient physical activity and insufficient duration of outdoor activity were predominant patterns of clustering. The median number of health-risk behaviors was 4.00 (interquartile range, 2.00) per capita. Multivariable linear regression analysis showed that boys (β=0.232), grade (junior high school, β=0.519; senior high school, β=0.427), urban area (β=0.241), living at school (β=0.395), family structure (single parental family, β=0.188; other families, β=0.344) and father's education level of primary school and below (β=0.369) were factors affecting clustering of health-risk behavior among primary and high school students. Conclusions The detection of health-risk behaviors is high among children and adolescents in Yancheng City, and insufficient sleep, insufficient physical activity and insufficient duration of outdoor activity are predominant health-risk behaviors. Boys, junior high school and above, urban areas, living at schools, single parents, and fathers with a low educational level lead to a high degree of clustering of health-risk behaviors.

Objective To observe the effects of hyperbaric oxygen on atony after hemiplegia. Methods40 cases with hemiplegia were divided into 2 groups: treatment group (n=17) accepted hyperbaric oxygen and rehabilitation, while control group (n=23) accepted rehabilitation only. The muscle strength, muscle tone and elderly mobility scale (EMS) were measured before and after treatment. ResultsAfter 20 times of treatment, the muscle strength, muscle tone and scores of EMS improved in both groups (P<0.01), and was more significantly in treatment group than in control group (P<0.05). ConclusionHyperbaric oxygen can facilitate the recovery of muscle strength and muscle tone in hemiplegia patients, and improve their motor function.

Aim To explore the effect of m-Nisoldipine(m-Nis) on 5-HT-induced proliferation,migration of rat PASMCs and to study the mechanisms.Methods PASMCs were cultured with the explant technique,and were divided into 6 groups:control group,5-HT(1 μmol·L~(-1)) group and m-Nis(10~(-5),10~(-6),10~(-7),10~(-8) mol·L~(-1))group.MTT assay was used to evaluate the proliferation of PASMCs,and transwell chambers were used to detect the migration of PASMCs.In addition,the expression of PCNA and the phosphorylation of ERK1/2 were evaluated by Western blot analysis.Results m-Nis inhibited the proliferation(P<0.05 or P<0.01)and migration(P<0.01)of rat PASMCs induced by 5-HT obviously.Similarly,Western blot analysis of PCNA indicated that the expression of PCNA was significantly higher in 5-HT group than that in control group(P<0.01).Whereas,in four m-Nis treated groups,the level of PCNA was markedly decreased(P<0.05 or P<0.01).Meanwhile,m-Nis 10~(-5),10~(-6) and 10~(-7) mol·L~(-1) pretreatment also reduced 5-HT-induced phosphorylation of ERK1/2 obviously(P<0.05 or P<0.01).Conclusion m-Nis inhibits 5-HT-induced proliferation and migration of rat PASMCs obviously,which may be related to the inhibition of PCNA expression and the blockage of ERK1/2/MAPK signal pathway.
