Objective To investigate the effect of percutaneous nephrostolithotomy (PCNL) on patients with different body mass index.Methods The clinical data of 84 patients with kidney stones who were treated with PCNL surgical treatment were enrolled in this study,and they were divided into different groups according to body mass index (BMI),including 16 cases of BMI ＜ 18.5 kg/m2(low BMI group),36 cases of 18.5 kg/m2≤BMI ＜24.0 kg/m2 (normal BMI group),32 cases of BMI≥24.0 kg/m2 (high BMI group),and the curative effect was evaluated.Results Three groups' operation time,multichannel gravel rate,stones clearance,length of hospital stay,blood transfusion rate had no significant difference (P ＞0.05),the incidence of complications in low BMI group [31.25％ (5/16)] was obviously higher than that in normal BMI group [5.56％(2/36)] and high BMI group [9.38％(3/32)],there was significant difference (P ＜ 0.05).Conclusion BMI of PCNL surgery influences on certain effect,low BMI will affect patients with surgery tolerance,cause complications increase,obesity wifl increase the difficulty of the operation.

Objective:To analyze the efficiency and influencing factors of Chinese medical and health resources. Methods:Based on the panel data of 31 mainland provinces from 2003 to 2011 in China, use the two-stage Malmquist-Tobit model to analyze. Results:The efficiency of Chinese medical and health resources shows an increasing trend, which is dual driven by improvement of technical efficiency and technological progress. The efficiency varies among different areas, and the descending order of efficiency value is east, west and center. The level of economic development, population density, the proportion of profitable hospitals, the levels of urbanization and education can promote Chinese medical and health efficiency with different extent. Conclusion:To improve the efficiency of Chinese medical and health resources, it needs to promote economic development level, allocating health resources reasonably, and advancing urbanization and education levels orderly.

Henoch-Sch(o)nlein purpura(HSP) is one of the most common vasculitides in children with many manifestations including skin purpura,arthritis,abdominal pain and renal involvement.The renal involvement(Henoch-Sch(o)nlein purpura nephritis,HSPN) is the principal cause of morbidity and major risk factor for prognosis in HSP.The paper reviewed the updated treatment strategy for HSPN.Accordingly,steroids,cyclophosphamide,mycophenolate mofetil,mizoribine,cyclosporine,triptolide,angiotensin converting enzyme inhibitors (ACEI) / angiotensin receptor blockers(ARB),plasma apheresis and tonsillectomy are possible indicator for the further therapy of HSPN.Furthermore,prospective randomized controlled treatment studies on children with severe HSPN would be needed.

Background and purpose:The majority of patients with gastric cancer are in advanced stage with either extensive invasion of tumor into the adjacent organs,lymph nodes or distant metastases when diagnosed.As a new anticancer drug of Taxanes,docetaxel has shown considerable promise in advanced gastric cancer through clinical study in these years.We conducted a clinical trial to compare the response and toxic reaction of weekly and 3-weeks'docetaxel /cisplatin/5-Fu treatment in advanced gastric cancer.Methods:80 patients were deviede into two groups.Ggroup A:Docetaxel 25 mg/m2 iv d 1,8,15,cisplatin 25 mg/m2 iv d 1-3,5-FU 500 mg/m2 iv d 1-5 q4w.Group B:Docetaxel 75 mg/m2 iv d 1,cisplatin 25 mg/m2 iv d 1-3,5-FU 500 mg/m2 iv d 1-5 q3w;The clinical responses were assessed after two cycles.Toxicity was assessed every cycle.Results:There was 1 CR in 40 cases,16 with PR,14 with SD in group A;there was 1 CR in 40 cases,17 with PR,14 with SD in group B.The overall response rates were 42.4% and 45.0% in group A and B,respectively.Grade Ⅲ/Ⅳ neatropenia were 32.5% and 77.5% in group A and B.The major non-hematologic toxicity was weakness.Grade Ⅲ/Ⅳ weakness were 22.5% and 42.5% in group A and B.Conclusions:The response rates were similar between groups A and B.The occurrence of hematological toxicity and weakness were lower in weekly treatment group.

Objective To explore the improvement of minocycline on negative symptoms in patients with schizophrenia and its influence on tumor necrosis factor (TNF)-α.Methods Patients with schizophrenia were randomly assigned into two groups.One was olanzapine combined with placebo group (control group, 37 cases).The other was olanzapine combined with minocycline group (treatment group, 200 mg ·d-1,po,bid, 38 cases).Both groups were assessed by the positive and negative syndrome scale (PANSS), the scale for the assessment of negative symptoms (SANS), and also tested the level of TNF-α before and after 12 weeks treatments.Results After 12 weeks treatments, the scores of SANS and PANSS in treatment group were significantly lower than those of control group (P<0.05).The level of TNF-α in treatment group[(6.5±1.3) pg ·mL-1]was significantly lower than that of control group[(7.6±1.8) pg ·mL-1] (P<0.01).Conclusion Minocycline can improve negative symptoms in patients with schizophrenia, and the mechanism may be related to lower the level of TNF-α.

Expression of gamma interferon (IFN-?)-like substance in adrenal pheochromocytoma was investigated with immunohistochemical technique. In 15 out of the 16 cases of adrenal pheochromocytoma positive IFN-@-like immunoreactive substance was detected in the cytoplasm of the tumor cells, whereas in adrenal tissues adjacent to adrenal tumors in 26 cases (pheochromocytoma 12, adrenal corti-col tumors 12, others 2) only two with pheochromocytoma showed positive IFN-?-like immunoreactive substance in the cytoplasm of zona reticularis cells. The results suggest that IFN-? may be a kind of antigen associated with differentiation of cell.

Objective This study was designed to determine the serum CA-Hb 3 level in human colorectal carcinoma and analyze its clinical significance.Methods The level of serum CA-Hb 3 was measured by ELISA in 72 patients with colorectal carcinoma and 36 normal persons as the control group.Results The level of serum CA-Hb 3 in colorectal carcinoma was significantly higher than that of normal control .The level of serum CA-Hb 3 was positively related with tumor size,clinical pathological staging.With progression of clinical pathological staging (Dukes'stage),the level of CA-Hb 3 increased significantly,but its relation to tumor size,age,and sex was not significant.Conclusion Serum CA-Hb 3 assay may be a potentially valuable marker in assessment of pathological staging and judgement of clinical prognosis of colorectal carcinoma.

AIM: To investigate the effect of homocysteine (Hcy) on secretion and expression of interleukin-6 (IL-6), which is a multifunctional proinflammatory cytokine, in cultured rat vascular smooth muscle cells (VSMCs). METHODS: Rat VSMCs were stimulated with Hcy. Cell ELISA was performed to measure the expression of IL-6 protein and semiquantitative RT-PCR was used to dectect the IL-6 mRNA expression. RESULTS: Compared with control, treatment of 0.25 mmol Hcy for 6 h could increase IL-6 production. In addition, Hcy concentration-dependently increased the expression of IL-6 protein in these cells. 0 1 mmol/L, 0 25 mmol/L Hcy increased IL-6 production 1 4-fold and 3 4-fold, respectively Furthermore, RT-PCR analysis demonstrated that homocysteine also enhanced IL-6 mRNA expression in a concentration- and time-dependent manner.CONCLUSION: Homocysteine can induce IL-6 expression in VSMCs and elicit vascular inflammatory response, which may thereby influence the pathogenesis of atherosclerosis.

Using immunohistochemical method,the antigens were shown to be mainly located in the cecum,tegument,esophagus,pharynx,excretory bladder,uterus and oral sucker of Pagumogonimus skrjabini.Histochemical analyses showed that antigens contained enzymes such as acid phosphatase (ACP),alkaline phosphatase (AKP),and acetyleholinesterase (AChE).Other chemical substances,for example,alkaline protein,basic protein,glycogen and acid mucopolysaccharides were also detected in the antigens of P.skrjabini.
