Objective To observe the effect of acupuncture on apoptosis and Caspase-9 expression in hippocampus of cerebral ischemia (CI) rats. Methods Thirty male SD rats were randomized into control, CI and CI + acupuncture group, with 10 cases in each group. CI model was established by occlusion of the unilateral middle cerebral artery. "Baihui" (GV20) and "Shuigou" (GV26) were acupunctured once daily for 7 days. The apoptosis and expression of protein Caspase-9 in hippocampus was displayed by HE staining and immunohistochemical method. Results In comparison with the normal control group, Caspase-9 immune reaction (IR) positive cells in the hippocampus of CI group increased significantly (P

Objective To observe the effect of electroacupuncture (EA) and acupuncture (A) on the proliferation of stem cells in the subependymal zone (SPZ) of the lateral ventricle and the frontal lobe cortex in hyperlipemia(HL) combined with cerebral ischemia (CI) rats. Methods A total of 72 male SD rats were randomized into control,HL,HL+ EA,CI,CI+A,HL+CI,HL+CI+EAⅠ and HL+CI+EAⅡgroups (n= 9 /group).HL model was established by feeding the animals with high fat forage for 6 weeks and CI model was established by FeCl3-induced occlusion of the unilateral middle cerebral artery. EA was applied to "Sanyinjiao" (SP 6) and "Fenglong" (ST 40) once daily for 17 days for HL+ EA group; and acupuncture to "Baihui" (GV 20) and "Shuigou" (GV 26) once daily for 7 days for CI+A group. For HL+CI+EA Ⅰ group,EA was applied to SP 6+ST 40 first before CI,once daily for 10 days,followed by EA of SP 6+ST 40 and acupuncture of GV 20+GV 26 for 7 days after CI. For HL+CI+EA Ⅱ group,no treatment was given before CI,then,acupuncture of GV 20+GV 26 and EA of SP 6+ST 40 were given once daily for 7 days after CI.The immunoactivity of Nestin and proliferation cell nuclear antigen (PCNA) of SPZ was detected by immunohistochemistry.Results In comparison with normal control group,the numbers of both Nestin and PCNA immunoreaction (IR) positive cells in the dorsolateral extension and the wall of the lateral ventricle of the brain increased significantly in CI and HL+CI groups (P0.05). Conclusion EA can upregulate Nestin and PCNA expression of the dorsolateral extension and the wall of the lateral ventricle of the brain on the ischemic side in rats with CI,and with HL+CI,which may contribute to its effects in promoting the proliferation and migration of neural stem cells in the brain.

OBJECTIVE:To observe the clinical efficacy and safety of Fuyankang combined with azithromycin in the treat-ment of pelvic inflammatory disease. METHODS:90 patients with pelvic inflammatory disease were selected and randomly divided into observation group and control group,with 45 cases in each group. Control group was given Lactose acid azithromycin for injec-tion 500 mg,ivgtt,qd,and then Azithromycin capsule 250 mg,po,qd;observation group was additionally given Fuyankang Tab-let 1.56 g,tid,on the basis of control group. A treatment course of 2 groups lasted for 7 d,and both received 3 courses of treat-ment. Clinical efficacies of 2 groups were observed as well as the level of CRP,IL-2 and life quality score before and after treat-ment,and the occurrence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 97.78%,which was significantly higher than that of control group (86.67%),with statistical significance (P<0.05). The level of CRP,IL-2 and life quality score of 2 groups were improved significantly after treatment,and the observation group was more better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Fuyankang combined with Azithromycin is effective for pelvic inflammatory disease,and can improve the quali-ty of life,reduce inflammation cytokines infiltration and the generation of inflammatory medium with good safety.

ObjectiveTo explore the appropriate teaching methods for medical international students.MethodsTotally 84 students in grade 2005 and 63 students in grade 2006 took part in clinical skills training in 2010 and 2011.The traditional method was employed in grade 2005 and interactive teaching and imagery training was applied in grade 2006 combined with the traditional methods.ResultsThe scores of clinical skill tests ( posterior thorax puncture test,abdomen puncture test,bone puncture,catheterization test) were significantly higher in grade 2006 than in grade 2005 with statistical differences,P ＜ 0.01.The clinical skill test scores were not statistically different between grade 2005 and 2006 before training,P ＞ 0.05,but the scores were statistically different between grade 2005and 2006 after training,P ＜ 0.05.Conclusion Using polynary teaching methods synthetically is helpful to improve the clinical skill training effect for medical international students.

Objective To investigate the expression of livin in hepatocarcinoma tissues and its relationship with hepatitis B virus X protein. Methods Immunohistochemistry was used to detect the expression of livin in 30 cases of hepatic carcinoma tissues and 10 cases of normal liver tissues. Stable L02 cell hne tansfected with HBx was established. Real-time PCR and Western blot were used to observe the expression of livin gene before and after the HBx transfeetion. Results The protein expression of livin was higher in hepatocarcinoma tissues than in normal tissues, and correlated with the exist of portal vein cancer embolus (t = 2.24, P = 0.033 ; P<0.05), but it was not correlated with cancer size or classification pathologically(t = 1.688, P = 0.103 ; γ = - 0.137, P = 0.471 ; P＞0.05). Livin Mrna expression was up-regulated after the HBx gene transfection (t = 6.73, P<0.05). Conclusions Apoptosis inhibition induced by livin up-regulation may play a role in pathogenesis and development of hepatocarcinoma. HBx up-regulates livin expression at transcriptional level.

Objective This study evaluated the effects of a systematic intensive health education intervention in community-dwelling elderly individuals with hypertension. Methods Using a cluster sampling method,we selected two neighborhoods in the Taiyuan Xiyu community,which were located 8 km apart.We randomly assigned all elderly community residents who were diagnosed with hypertension to one of two groups according to the inclusion and exclusion criteria:the intervention group(n=314)or the control group (n=319). The intervention group received a 1-year systematic intervention of intensive health education, whereas the control group only received 1 year of routine health education. After 1 year, blood pressure, body mass index, fasting blood glucose, blood lipid levels, and changes in poor health behaviors were evaluated in both groups. Results The systolic blood pressure of hypertensive patients in the intervention group decreased from(136.75±14.62)mmHg(1 mmHg=0.133 kPa)before the intervention to (131.11 ± 7.71) mmHg after the intervention. The diastolic blood pressure of hypertensive patients in the intervention group decreased from(81.22±7.71)mmHg before the intervention to(80.45±5.12)mmHg after the intervention. Body mass index, fasting blood glucose, total cholesterol, and low-density lipoprotein cholesterol decreased from(25.02±3.09)kg/m2,(5.85±1.50)mmol/L,(5.23±0.99)mmol/L,and(2.98±1.07) mmol/L before the intervention to(24.22±2.73)kg/m2,(5.23±1.50)mmol/L,(4.42±1.31)mmol/L,and(2.73±0.95)mmol/L after the intervention in the intervention group,respectively.The differences before and after the intervention were significant (P<0.05, P<0.01). The systolic blood pressure of hypertensive patients in the control group decreased from (137.83 ± 13.83) mmHg before the intervention to (133.14 ± 7.69) mmHg after the intervention. The diastolic blood pressure of hypertensive patients in the intervention group decreased from (82.04 ± 7.62) mmHg before the intervention to (81.22 ± 5.29) mmHg after the intervention. Fasting blood glucose and total cholesterol of hypertensive patients in the control group decreased from (5.67±1.49)mmol/L and(5.27±1.02)mmol/L before the intervention to(5.47±1.53)mmol/L and(4.70±1.25) mmol/L after the intervention,respectively.The differences before and after the intervention were significant (P<0.05,P<0.01).The difference between the two groups in systolic blood pressure,body mass index,fasting blood glucose, and total cholesterol were statistically significant (P<0.05, P<0.01). After the intervention, both groups showed statistically significant behavioral changes in smoking cessation, physical exercise, low-sodium diets, and weight control (P<0.01). Conclusion A systematically intensive health education intervention was effective in improving blood pressure and unhealthy lifestyles for community-dwelling elderly patients with hypertension.

Objective To investigate the role of pre-chemotherapy hemoglobin and platelet levels in the effect of chemotherapy and prognostic outcome in patients with International Federation of Gynecology and Obstetrics(FIGO) stage Ⅰ b2 - Ⅱb cervical cancer treated with neoadjuvant chemotherapy followed by radical hysterectomy.Methods From January 1999 to December 2010,111 patients with FIGO stage Ⅰ b2 - Ⅱ b who underwent chemosurgical treatment at the department of obstetrics and gynecology in Peking Union Medical College Hospital were reviewed.The median age of patients was 42 years (range:21 -68 years).The median level of prechemotherapy hemoglobin and platelet levels was 127 g/L and 266 ×109/L,respectively.Chemotherapy response was evaluated according to the WHO criteria,including complete response (CR),partial response (PR),arable disease (SD) and progressive disease (PD).Patients who achieved CR or PR were defined as responder.Rates of clinical response were compared with the clinicalpathological variables using chi-square test.Multiple logistic regression was carried out to evaluate the relationship among the probability of achieving an optimal clinical response and the variables.The log-rank test was used to compare the homogeneity of progression-free survival and overall survival functions across strata defined by categories of prognostic variables.The Cox proportional hazard model was used to assess the significance of potential prognostic factors for progression-free survival and overall survival.Results All patients received one to three cycles of chemotherapy.After the neoadjuvant chemotherapy,9 patients achieved CR,77 patients PR,23 patients SD, 2 patients PD.The overall response rate was 77.5％(86/111).By univariate analysis,the clinical response rate was associated with tumor grade( P =0.026),deep cervical stromal invasion ( P =0.029 ) and positive lymph nodes ( P =0.048 ).By multiple logistic regression,deep cervical stromal invasion ( P =0.015 ) and positive lymph nodes ( P =0.031 ) were independent predictors of optimal clinical response.By log-rank test,5-year overall survival rate and 5-year progression-free survival rate were associated with lymph nodes metastases status and lymphovascular invasion ( P =0.000),but not with hemoglobin and platelet levels( P ＞ 0.05 ).By Cox regression model,lymph nodes metastases status and lymph-vascular space involvement ( P ＜ 0.01 ) were independently prognostic factors of 5-year overall survival rate and 5-year progression-free survival rate.Conclusion Pretreatment hemoglobin and platelet levels were neither predictors of clinical response to chemotherapy nor prognostic factors.
