Objective To evaluate the association between serum ferritin and the risk of cardiovascular disease among the Chinese population.Methods Based on the data from China Health and Nutrition Survey 2009, we used the Framingham risk score to calculate the 10-year risk of cardiovascular disease and analyzed the association between serum ferritin and the risk of cardiovascular disease in different gender by logistic regression analysis.Results Among 6 551 respondents, 3 035 (46.3%) were males and 3 516 ( 53.7%) were females whose mean age were ( 49.3 ±13.8 ) and ( 49.2 ±13.7 ) years, respectively.The median level of serum ferritin was 75.08 ( 36.71 -138.75 )μg/L.According to the 10-year risk of cardiovascular disease calculated by the Framingham risk score , the low risk group, middle risk group and high risk group were accounted for 79.5%( n=5 207 ) , 15.7% ( n=1 028 ) and 4.8%( n=316), respectively.The median of serum ferritin (121.61 vs.46.14, P<0.01) and the Framingham risk score (8.6 ±6.0 vs.7.3 ±1.6, P<0.01) of males were higher than those of females.The percentages of the middle risk group ( 30.6% vs.2.8%) and high risk group ( 9.8% vs.0.5%) of 10-year risk of cardiovascular disease in males were higher than those in females ( P <0.01 ).The 10-year risk of cardiovascular disease ≥10%increased with the increasing of serum ferritin in females ( trend P<0.01 ) but not in males.Conclusion Serum ferritin levels are positively correlated with the risk of cardiovascular disease in female Chinese.

To analyze the acupuncture treatment for impotence in 130 kinds of classical medical books by computer,and summarize the rules of acupuncture for this disease.The results showed that selection of acupoints along the meridians,selection of acupoints by boay parts,selection ofacupoints by pattern identification are the laws ofacupuncture for this disease.

The objective structured teaching evaluation (OSTE) is a new method for training and objective assessment of the teaching ability of clinical faculty by using standardized students and teaching scenario.It is mainly used to evaluate training programs,train teaching skills and assess teaching ability of clinical faculty.The differences and association between teaching ability,teaching skills and teaching scenario should be clarified before designing OSTE.Although there are some differences in various studies,OSTE can be summarized into two aspects:teaching administration knowledge and special teaching skills.Given the great potential of OSTE in training and assessing faculty,medical educators in general should actively explore its concept and application.

OBJECTIVE: To investigate the effects of salvianolic acid B (SA-B) on portal hypertension induced by endothelin-1 in rats. METHODS: Twenty-eight Sprague-Dawley rats were randomly divided into four groups: ET-1 group, ET-1+SA-B group, ET-1+ET(A)R blocker (BQ-123) group and ET-1+ET(B)R blocker (BQ-788) group. The rats of ET-1+SA-B group underwent intragastrical administration of salvianolic acid B for five days before ET-1 injection, while in three other groups' drinking water was given. In BQ-123 group or BQ-788 group, an intravenous injection of BQ-123 or BQ-788 via femoral vein was administered 30 minutes prior to ET-1 injection. Then changes of portal pressure, cervical artery pressure and heart rate were monitored continuously. RESULTS: After ET-1 injection, the portal pressure of all rats in the ET-1 group increased significantly, while slightly in groups that pretreated with SA-B, BQ-123 or BQ-788. CONCLUSION: SA-B can attenuate the elevated portal pressure induced by ET-1 with effect similar to ETR blocker.

Objective To investigate the application of video-mediastinoscopic biopsy and treatment for pleural effusion. Methods Thirty-two patients with pleural effusion received mediastinoscopic biopsy or treatment. The patients were maintained at a lateral decubitus. A 2 cm incision was made along the midaxillary line for introducing the mediastinoscope. The pleural fluid was drawn out and exploration with biopsy was conducted under mediastinoscope. For 25 patients with malignant hydrothorax, talcum powder was applied for pleurodesis. Results The operation time was 30~70 min (mean, 42 min). A confirmative diagnosis was obtained by video-mediastinoscopy in all the 32 patients, including adencarcinoma in 22 patients, poorly differentiated squamous cell carcinoma in 2, invasive thymoma in 1, tuberculosis in 5, and inflammation in 2. All the operations were successful and the patients recovered smoothly without severe postoperative complications. Conclusions Video-mediastinoscopy is one of effective methods for biopsy and treatment of pleural effusion.

OBJECTIVE To study the antiviral effect of Shenghuangketong ointment(SO)in vivo experiments.METHODS The inhibition effect of SO on the HSV-infected mice with the estimation of its antiviral action.RESULTS SO had an obvious antiviral action and the inhibition effect on the HSV-infected mice.There was significant difference P

OBJECTIVE To investigate the carbapenemase genotype of carbapenem-resistant Acinetobacter baumannii isolated from Beijing Tiantan Hospital. METHODS Twenty strains of carbapenem-resistant A. baumannii were collected from Beijing Tiantan Hospital. OXA-23,OXA-24,IMP and VIM genes were detected by polymerase chain reaction (PCR) and DNA sequencing method. RESULTS All strains produced OXA-23 carbapenemases by PCR and sequencing,and OXA-24,IMP and VIM genes were not found. CONCLUSIONS OXA-23 Carbapenemase is a main type of carbapenem-resistant A. baumannii in Beijing Tiantan Hospital.

OBJECTIVE To investigate the inhibiting effect of Shenghuangketong Ointment on the herpes simplex virus(HSV)-Ⅰ and HSV-Ⅱ. METHODS Histocyte cultivation and cytopathic effect(CPE) were used to examine the inhibiting effect on the HSV-Ⅰ and HSV-Ⅱ. RESULTS EC 50 of Shenghuangketong Ointment on the HSV-Ⅰ and HSV-Ⅱ for HEP-2 cells was 0.94-1.12 mg/ml and 0.94 mg/ml,therapentic index(TI) was 4.0～4.7 and 4.7,respectively. CONCLUSIONS The Shenghuangketong Ointment has inhibiting effect on the HSV-Ⅰ and HSV-Ⅱ.
