Objective: To observe the efficacy of mirtazapine in the treatment of depression after cerebral infarction and its effect on rehabilitation of neurological functions. Methods:117 patients with acute cerebral infarction comorbid with major depression were randomly allocated to two groups treated with mirtazapine (57 cases) or not (60 cases). Hamiltion Depression Rating Scale (HAMD), Zung's Self-rating Depression Scale(SDS), modified Edingburgh-Scandinavian Stroke Scale (SSS) and Activity of Daily Living(ADL) were measured at baseline, 2 weeks, 4 weeks, 8 weeks and 6 months after randomization.Results:At the end of 6 months trial, the effective rate for depression of mirtazapine group was 100%, including 41 with relief (41/57, 71.9%); while that of control group was 13.4% (3/60), with only 4 with relief (6.7%). For neurological function, 78.9% (45) patients in mirtazapine group had significant improvement, that number in control group was 31 (51.7%). From the third week, patients in mirtazapine group had better ADL results than baseline (31.2?11.2/39.2?15.8), at the end of 6 months, their activity of daily life was much better than that of control (15.7?5.4/21.8?9.7, t=4.17,P

Objective To investigate the relationship between the related indexes with rheumatic heart disease (RHD) and its clinical significance .Methods The medical records information in 236 patients with rheumatic fever caused cardiac were collected and divided into the RHD group ,simple rheumatic fever group and normal healthy control group .The levels of related indiexe such as Mb and cTnI were detected in the three groups .Results The Mb ,cTnI and CK‐MB and NT‐proBNP had statistical differences between the RHD group and simple rheumatic fever groups (P<0 .05);the levels of ESR ,RF ,CRP ,cTnI ,Mb ,CK‐MB ,CK and NT‐proBNP had statistically significant differences between the RHD group and healthy control group (P<0 .05);With the NT‐proB‐NP level of 136 .17 pg/mL as the critical value ,the sensitivity ,specificity ,positive predictive value and negative predictive value of NT‐proBNP for diagnosing RHD were 95 .48% ,90 .15% ,86 .7% and 97 .86% respectively .Conclusion The levels of blood cTnI , Mb and CK‐MB in the patients with RHD are significantly higher than those in the normal controls ,so detecting the serum NT‐proBNP concentration is a sensitive indicator for early diagnosis of RHD .

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

Objective To discuss the impact of a immunosuppressive protocol using tacrolimus combined with mycophenolate without steroid on glycometabolism after liver tansplantation (LT).Methods 295 adult liver transplant recipients were under investigation and divided into two groups,to receive immunosuppression therapy using tacrolimus and mycophenolate with (n =142) or without steroid (n =153).The fasting blood-glucose level,rate of hyperglycemia,infection and metabolic complications were followed up at 1st,2nd,4th,8th,12th,16th,20th and 24th week after LT.Results There were no significant differences between two groups in gender,age.body weight and FBG level before LT.In both groups,the FBG levels were significantly elevated immediately and reached the peak at 1st week after LT,then gradually decreased over time post-LT.The FBG level and rate of hypcrglycemia were significantly lower in steroid-free group than in steroid group in each observation time point with the differences being significant (P＜0.05) at 4th week post-LT.The overall rate of hyperglycemia was 52.9％ in steroid free group and 76.8％ in steroid group with the difference being significant between the two groups (P＜0.05) and a risk ratio of 2.94 (steroid-free group versus steroid group).The rate of acute rejection was slightly higher in steroid-free group (8.50 ％ ) than in steroid group (7.75％ ) (P ＞ 0.05 ).Also the incidence of intention badness,infection and hypercholesterinemia was significantly lower in steroid group than in steroid-free group.Conclusion The immunosuppressive protocol without steroids is safe and effective of reducing the risk of hyperglycemia and metabolic complications after LT.

Ischemic stroke has become one of the leading causes of disability and death in China.A number of studies have confirmed that hypoalbuminemia is an independent risk factor for ischemic stroke.It affects the severity of ischemic stroke and outcomes.This article reviews the rehtionship between serum albumin and ischemic stroke,the cause of low albumin level,the effect of albumin on ischemic stroke,and how to supplement albumin in order to improve the clinician's attention for hypoalbuminemia in patients with ischemic stroke and supplement nutrition timely and reasonably.

Objective To investigate the effects of exercise on memory impairment in demented mice and possible molecular mechanisms.Methods Thirty Kunming nice were divided into a normal control group,a dementia group and a dementia plus exercise training group (exercise training group),10 mice/group. Dementia models were established by intraperitoneal injection of scopolamine.Exercise training was begun 30 min after the injection and lasted for a 6-week period. A water maze test was performed after the exercise training. Brain-derived neurotrophic factor (BDNF) expression and protein kinase (Akt) phosphorylation in the hippocampus were detected by Western blot analysis.Nitric oxide (NO) content and superoxide dismutase (SOD) activity in the hippocampus were also measured.ResultsDementia models were successfully induced as indicated by prolonged escape latency in the water maze test.After exercise training the escape latency had shortened significantly and hippocanpal BDNF expression and Akt phosphorylation had increased.NO content increased and SOD activity decreased after the injections,but these effects were partially reversed after exercise training.Conclusions Exercise can improve spatial memory significantly after scopolanine-induced dementia in mice.The increased hippocampal BDNF expression and Akt phosphorylation,increased SOD activity and decreased NO content may partially explain the behavior improvement induced by exercise.

Aim To purify L-amino acid oxidase(LAAO) from the venom of Naja atra and study its effect on endothelial cells.Methods The NAV-LAAO was purified by ion-exchange chromatography and affinity chromatography.The MTT assay and Western blot were used to detect the viability and apoptosis of HUVEC.The tubule-forming was used to study the angiogenesis of cells.Results The NAV-LAAO was purified successfully from the venom of Naja atra.The molecular weight of NAV-LAAO was determined to be 58 ku by SDS-PAGE.NAV-LAAO effectively inhibited the growth and tubule-forming of HUVEC,and the 50% inhibitory concentration(IC50) was 21.42 mg?L-1.Compared with control,the levels of caspase-3 and caspase-8 increased in HUVEC treated with NAV-LAAO.Conclusions The NAV-LAAO is purified successfully from Naja atra venom by ion-exchange chromatography and affinity chromatography.The NAV-LAAO inhibits the growth and tubule-forming capacity of HUVEC in a dose-dependent manner.

Objectives To analyze the deployment of medical equipment and its impacts on medical services of hospitals.Methods Existing data collection,a survey of public hospitals and a chart review of acute myocardial infarction(AMI)inpatients were used to collect related data.Gini coefficients,Chi-square and multivariate model were used to analyze deployment of medical equipment and its impacts on medical services.Results The number of CTs and that of CTs per million population in Pudong new area were higher than those of MRIs and DSAs,and the distribution of CTs among districts in Shanghai was relatively equal(Gini coefficient was 0.20).But lack of DSAs in some public general hospitals had affected the AMI inpatient care.Conclusions Public hospitals and governments in China should keep at a balance the demand of medical services,deployment level of medical equipment,and financial affordability for the society,governments and hospitals.

ObjectiveTo determine the possible causes for functional delayed gastric emptying (FDGE) and its diagnosis and treatment. MethodsThe clinical data of 53 FDGE patients after subtotal gastrectomy from 1987 to 2001 were retrospectively analysed. ResultsAll the 53 patients were recovered and discharged. Among them, 11 were misdiagnosised as mechanical ileus and were reoperated on. ConclusionsThe main cause of FDGE may be the disturbance of gastrointestinal motility which may be caused by vegetative nerve injury during the operation. The main therapy is non-surgical treatment and reoperation should be avoided at the early stage.
