Objective To assess the effects of tegaserod on rat with visceral hypersensitivity. Methods Neonatal SD rats were randomized to receive colonic acetic acid irritation between postnatal days 8 and 21 as visceral hypersensitive model (Group H) or by saline intrarectally as control group (Group C). While rats were grown-up, rectal distention (RD) was performed by a balloon rapidly inflated with increasing volumes of saline (0.4, 0.8 and 1.2 ml) for 20 seconds at five-minute intervals. The 5 subgroups of Group H were injected randomly with saline, vehicle (1-methyl-2-thpyrrolidone) or tegaserod at doses of 0.1, 0.3 and 1 mg/kg i.p., respectively. The 2 subgroups of Group C were injected with saline or tegaserod at dose of 1 mg/kg i.p.. RD was performed 10 min after injection and abdominal withdrawal reflex (AWR) was recorded, and then c-Fos expression in spinal cord (L6-S1) was analyzed quantitatively by immunohistochemistry. Results 1) Compared to saline, vehicle did not affect AWR and c-Fos expression. 2) Compared to saline, tegaserod significantly (P

Objective To investigate the suicide behavior among middle school students in Kunming city and its relationship with family factors, and provide a theoretical basis for prevention and control of juvenile suicide behavior. Methods 1 164 junior to senior students in 5 middle schools in Kunming were investigated by anonymous self-administered questionnaire investigation, and the collected data were statistically analysed by using SPSS software. Results The total effective number of students was 1 163, including 548 boys, accounting for 47.1%, and 615 girls, accounting for 52.8%, with age of 11 and 18 years (15.17 ± 1.838) .Among them, 153 people considered suicide, accounting for 13.1%of the proportion. Family factors of suicide analysis found that family type, education level of the parents and the family economic situation had influences on the suicide behavior among middle school students. Conclusions The suicide behavior is more common in middle school students,and is influenced by the family factors including family type,cultural degree of parents and etc.,so we should strengthen the comprehensive intervention measures to prevent the occurrence of suicide behavior based on the influencing factors.

Objective To investigate the clinical value of 99mTc-MDP SPECT/CT whole body bone imaging in the diagnosis of bone metastasis of prostate cancer. Methods A total of 107 cases with prostate cancer were di-agnosed by SPECT whole body bone imaging from January 2013 to November 2016. SPECT/CT imaging of some ab-normal density collective focus found in whole body bone imaging were further carried out. Six months later ,whole body bone imaging and SPECT/CT were made again for review. In all diagnosis above ,99mTc-MDP were selected as bone imaging agent. According to the results of follow-up visit clinical and imaging diagnosis ,diagnostic perfor-mance indicators of whole body bone imaging and SPECT/CT were calculated. Results The different part of whole body bone imaging and SPECT/CT in the diagnosis of bone metastases was statistically significant(x2 = 23.000, P < 0.001). The diagnosis specificity and coincidence rate of SPECT/CT for bone metastasis were 100.0% and 98.1% respectively and they were significantly higher than those of whole body bone imaging(65.0% and 80.4%respectively). The differences were statistically significant(P < 0.05). After SPECT/CT diagnosis,a total of 193 undetermined lesions were found and 83 lesions of these were final diagnosed of bone metastases. Pelvic lesions were most in bone metastases ,accounting for 50.6%. Conclusion Whole body bone imaging can effectively determine the undetermined lesions , further SPECT/CT can significantly improve the diagnostic accuracy of prostate cancer bone metastasis.

Transforming growth factor-β(TGF-β), a member of the TGF-β superfamily, plays a role in multiple biological processes, including cell proliferation, differentiation, migration and tissue fibrosis, etc. Normally, TGF-βs widely express in normal tissues and most cell lines, such as macrophages and dendritic cells, But in pathological conditions, Cancer cells and cancer-associated fibroblasts also produce and secrete TGF-β. Scirrhous gastric cancer (SGC) is a special subtype of gastric cancer with rapid development, frequent peritoneal implantation, and accompanied by significant interstitial fibrosis deposition. these biological behavior characteristics all suggest that its occurrence and development are closely related to TGF-β expression, and TGF-β is considered to be associated with poor prognosis of the SGC. The use of antibodies and inhibitors of TGF-β and its signaling pathways can reduce the invasiveness of cancer cells and improve the prognosis of SGC patients. This paper reviews the expression and significance of TGF-β in SGC.

Objective To explore the effect of rehabilitation training start time after mastectomy on the recovery of the affected limb function. Methods 90 patients who received modified radical mastectomy were divided into groups A, B and C randomly. All the patients accepted the unified rehabilitation program, but started 1, 3 and 10 d after the operation respectively. They were evaluated with the Japanese Orthopaedics Association (JOA) assessment for affected shoulder 1, 3 and 6 months after operation. Results The score of JOA was the least in the group C (P<0.01) 1 month after operation, and was the most in the group A 3 months after operation (P<0.01). At the end of the 6th month, there was no difference among these groups (P>0.05). Conclusion The rehabilitation training can be started as early as possible.

The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.
