Objective To observe the effect of Wenxiao Granule on the expression of MCP-1 and TNF-? in experimental atherosclerosis rabbit, and explore its mechanism in treating atherosclerosis. Methods Thirty-six New Zealand rabbits were randomized to four groups: control group, Wenxiao granule group, Simvastatin group. They were fed a high-fat diet except normal group until the mature atherosclerotic plaques formed. The rabbits in two drug-treated groups were treated with respective drug for 8 weeks. All rabbits were sacrificed. The morphology and composition of atherosclerotic plaques in aortic roots were examined. The expression of MCP-1 and TNF-? were determined by immunohistochemical staining. Results The expression of MCP-1 and TNF-? in plaque of Wenxiao Granule group and simvastatin group were significantly dereased compared with the model group (P 0.05). Conclusion Wenxiao Granule can inhibit the expression of MCP-1 and TNF-?, which may stabilize plaque of atherosclerosis.

Objective To investigate the application value of human papillomavirus (HPV) combined with thinprep cytology test (TCT) detection in screening of cervical cancer. Methods 276 patients were enrolled to have HPV and TCT tests at Department of Gynecology, Shanxi Cancer Hospital from January to December in 2014. Pathological examine was applied to the patients with abnormal results of HPV and TCT. The diagnostic value of HPV, TCT and their combinations was evaluated by the diagnostic sensitivity and the rate of coincidence with the pathological examine results. Results The sensitivity of HPV and its coincidence with the pathological examine results were 81.52 % (225/276) and 79.56 % (179/225), respectively, while those of TCT were 87.68%(242/276) and 76.86%(186/242), respectively. The coincidence rate between the combination method and the pathological examination was higher (94.71%, 197/208) than the individual test. Conclusion HPV combined with TCT detection can reduce the misdiagnosis rate and improve the diagnostic accuracy rate, indicating that this method is of great value in the cervical cancer screening.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

OBJECTIVE:To observe clinical efficacy and safety of Ebastine tablet combined with Chushi zhiyang ointment in the treatment of hand keratinizing chapped eczema. METHODS:135 cases of hand keratinizing chapped eczema were divided into control group A(45 cases),control group B(43 cases)and treatment group(47 cases)according to treatment regimen. Control group A was orally given Ebastine tablet,10 mg each time,qd;control group B was given Chushi zhiyang ointment alone,twice a day,morning and evening,applying thin layer of ointment on the affected area;treatment group was given same dose of Ebastine tablet orally and applied Chushi zhiyang ointment on the affected area. 3 groups received treatment for consecutive 4 weeks. Clinical efficacies of 3 groups were observed as well as the scores of pruritus,skin lesion area,keratinization,rhagades and VAS before and after treatment.

CONCLUSIONS:Ebastine tablet combined with Chushi zhiyang ointment is effective for hand keratinizing chapped eczema,and can significantly improve the skin of patients with good safety.

Background The protective effects against reperfusion injury of cardioprotective drugs have recently been evaluated and found to be inadequate. Guanxinshutong (GXST), a combination of the traditional herb and Mongolian medicine, is effective and safe in treating angina pectoris in clinical trials. We assess the cardioprotective effects of GXST against myocardial ischemia and reperfusion (MI/R) injury in rats and explore its possible mechanism. Methods Forty-five male Sprague Dawley rats were randomized into three groups: non-MI/R group (Sham, n = 15), MI/R group treated with vehicle (Control, n = 15) and MI/R group treated with GXST (Drug, n = 15). MI/R was induced by ligation of the left anterior descending coronary artery (LAD) for 30 minutes, followed by 2/24 hour reperfusion in the Control and Drug groups. In the Sham group, the LAD was exposed without occlusion. GXST powder (in the Drug group) or saline (in the Control and Sham groups) were administered via direct gastric gavage from 7 day prior to surgery. Blood samples were collected from the carotid artery (10 rats each group) after 2 hours of reperfusion, to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) using enzyme-linked immunosorbent assays. The animals were then sacrificed and the hearts were harvested for histopathology and western blot analysis. Infarct size was measured in the remaining five rats in each group after 24 hours reperfusion. Results GXST significantly decreased levels of TNF-α, IL-1β, IL-6, ICAM-1, apoptosis index (AI) and infarct size. GXST also obviously inhibited nuclear factor kappa B (NF-κB) activity when compared with the Control group (all P < 0.05). Conclusions GXST is effective in protecting the myocardium against MI/R injury in rats. Its possible cardioprotective mechanism involves inhibition of the inflammatory response and apoptosis following MI/R injury.

BACKGROUND: How to effectively treat recurrent osteoporotic vertebral compression fractures in the elderly over 65 years has become an issue of attention in the clinic. OBJECTIVE:To evaluate the clinical efficacy of percutaneous vertebroplasty with polymethylmethacrylate bone cement for treating elderly recurrent osteoporotic vertebral compression fractures. METHODS:Twenty-four patients with elderly osteoporotic vertebral compression fractures were divided into polymethylmethacrylate bone cement group (minimaly invasive group) and conservative treatment group on a voluntary basis (n=12 per group). Visual analog scale score for low back pain, Oswesty dysfunction index, ratio of the anterior/posterior margin height of the injured vertebra, Cobb angle and adverse reactions were compared between the two groups before and after treatment. RESULTS AND CONCLUSION:The 12-month folow-up was completed in al the patients. There was one case of bone cement breakage during treatment in the minimaly invasive group and one case of lower limb deep venous thrombosis in the conservative treatment group at 1 month after treatment. Compared with the conservative treatment group, the visual analog scale score, Oswesty dysfunction index, and Cobb angle were significantly lower, but the ratio of the anterior/posterior margin height of the injured vertebra was significantly higher in the minimaly invasive group at 3 days, 1, 3, 6 and 12 months after treatment (P < 0.05). These findings indicate that percutaneous vertebroplasty with polymethylmethacrylate bone cement for elderly recurrent osteoporotic vertebral fractures can strive for short-term pain relief and long-term recovery of the vertebral height and spinal Cobb angle, thereby significantly improving patient’s quality of life.

Objective:To evaluate the diagnostic accuracy of 64-channel multislice spiral computed tomography(MSCT) in subjects with presentations suggestive of stable angina or acute coronary syndrome. Methods: Subjects received both 64-channel MSCT and coronary angiography, from Feb. 2006 to Feb. 2007, were enrolled for retrospective analyses. Results of the quantitative coronary angiography were used as the "Golden criteria", accuracy of 64-channel MSCT were evaluated in the overall sample, as well as in subjects suspected of stable angina and acute coronary syndrome. Results: A total of 120 subjects were enrolled in the analyses. On the patient level, the sensitivity, specificity, and accuracy of 64-channel MSCT in detecting significant stenoses were 92.5%, 50%, and 87.5%, respectively. The overall ROC area under curve was 0.71. On the artery level, sensitivity, specificity, positive predictive value, negative predictive value, and ROC area under curve of 64-channel MSCT were 69.9%, 83.8%, 81.1%, 73.7%, and 0.77, respectively. Further analyses showed the sensitivity, specificity, positive predictive value, negative predictive value, and ROC area under curve of 64-channel MSCT in subjects presenting as stable angina and in subjects presenting as acute coronary syndrome were as follows: 70.2% vs 69.2%, 76.2% vs 86.0%, 74.7% vs 85.6%, 71.9% vs 69.9%, and 0.73 vs 0.78. Conclusion: The accuracy rates of 64-chanel MSCT in subjects presenting as stable angina and in subjects presenting as acute coronary syndrome were similar.
