Objective To analyze the genotype distribution of human papillomavirus( HPV) strains and their epidemiological characteristics in cervixes of Chinese females. Methods Pertinent litera-tures published during 2004 to 2013 were screened from PubMed,China National Knowledge Infrastructure (CNKI)and Wanfang database for data analysis. Results There were 245 studies screened out for the me-ta-analysis. A total of 661 658 cases met the inclusion criteria,ranging from 16 to 87 years old. All prov-inces and territories of China were covered by the data. The overall rate of HPV infection in cervix was 25. 0% among Chinese females. The predominant high risk genotype of human papillomavirus strains was HPV16,followed by HPV52,HPV58,HPV18,HPV33 and HPV31. HPV52 and HPV58 genotypes were more prevalent than HPV18 genotype. HPV35 and HPV45 genotypes were less popular. Conclusion The study suggested that the HPV infection showed obvious regional differences in genotypes. The genotype dis-tribution of HPV infection in China was different from that in other regions of the world. There were differ-ences with genotype distribution of HPV strains among seven geographic regions of China.

Flavonoid naringin is widely distributed in various types of plants and is an important component of herbal Drynaria. In previous studies, Drynaria has been demonstrated to have inhibitory effects on inflammatory responses and bone destruction and exert anabolic effects on bone, has been widely used in the clinical treatment. Naringin, was in the stage of experimental yet. The experimental results have confirmed that naringin suppressed inflammation including arthritis by lowering the expression of inflammatory cytokines, and the mechanism can be explained as reducing the expression of NF-κB. Naringin has been shown to increase osteoblast proliferation by increasing the expression of BMP-2, inhibit osteoclast activity by reducing the expression of RANKL. In animal experimental, naringin was useful for osteoporosis, and the mechanisms are in-depth studies. Research in the field of traditional Chinese medicine and orthopedics, naringin as a explicit material structure in the components of Drynaria, has been concerned about the experimental studies, it is not only prosperity the development of traditional Chinese medicine research,but also ready for clinical studies anti-inflammatory and bone effects of naringin in the future.

Aortic dissection is a common disease which is very dangerous,with high mortality rate.Bypass graft for the treatment of DeBakey Ⅲ dissection has outstanding advantages than the ordinary replacement of thoracic aorta,and some patients will inevitably require the use of the procedure.The purpose of this study was to explore the impact of the subclavian artery-abdominal aorta bypass graft on hemodynamic parameters in the false lumen and the effectiveness of surgical treatment.First of all,the idealized three-dimensional geometric models of DeBakey Ⅲ aortic dissection and its subclavian artery-abdominal aorta bypass graft operation were constructed,respectively.Then the models were imported into ANSYS 11.0 for finite element analysis.Results of numerical simulation showed that both velocity and pressure of the blood flow were reduced after bypass graft at the entrance and in the internal sac of false lumen,which is very favorable for reducing the impact of blood flow on false lumen,slowing down the further expansion of entrance,preventing the breakdown of false lumen,and promoting the healing of dissection.Therefore,the subclavian artery-abdominal aorta bypass graft operation is an effective surgical method for the treatment of DeBakey Ⅲ aortic dissection in some particular cases.This operation is with great prospects for clinical application.

Objective To observe the effect of acupuncture plus thunder fire moxibustion plus deglutition training plus VitalStim electrical stimulation on patients with deglutition disorder of early stroke.Methods 80 patients with deglutition disorder of early stroke were randomly divided into treatment group and control group,40 cases in each group.The treatment group was treated with acupuncture plus thunder fire moxibustion plus deglutition training plus VitalStim electrical stimulation,while the control group was only treated with deglutition training.The therapeutic effects of all patients were assessed by using drinking experiment before therapy and twenty times after therapy. Results The total effective rate of the treatment group was 97.5%,which was significantly higher than 82.5% of the control group,the difference was statistically significant(χ2 =12.50,P <0.05).Watian integration of the two groups were decreased after treatment,the difference was significant(t =5.606,9.056,all P <0.05),which of the treatment group was significantly lower than the control group,the difference was statistically significant(t =3.044,P <0.05). The lung infection rate and malnutrition rates in the control group were 10.0% and 20.0%,which were significantly higher than those in the treatment group(2.5% and 5.0%),the differences were statistically significance(χ2 =4.80, 10.29,all P <0.05).Conclusion Acupuncture plus thunder fire moxibustion plus deglutition training plus VitalS-tim electrical stimulation are beneficial to the recovery of swallowing functions to early swallowing disorder in patients and could avoid the incidence of aspiration pneumonia and malnutrition.

Objective To explore the effect of preservation of inclined fractured permanent molars by transverse fixation with screw post,and provide a practical method for reserving the inclined fractured permanent molars.Methods Clinical data of 50 patients with inclined fractured permanent molars by transverse fixation with screw post in the Department of Stomatology of Tianjin First Central Hospital between January 2010 to December 2011 were reviewed retrospectively.After fixing the crown with steel-wire binding and root canal treatment,the molars were drilled a hole buccolingually and placed screw post.The flowable light-curing composite resin was used to seal the crack and bond screw post to prevent the relative movement.All treated molars were restored with full crown.All patients were followed up for 10-60 months.The therapeutic effects were observed.Results After 5 year-follow-up,41 cases were cured completely,6 cases were cured clinically,and 3 cases failed treatment.Conclusion The transverse fixation with screw post and bonding technique can preserve the inclined fractured molars to gain chewing function and avoid or reduce the extraction of affected teeth,which provides a better restoration effect.
