Objective To evaluate the diagnostic value of hysteroscopy in comparison with hysteros- alpingography(HSG) in the detection of intrauterine abnormalities in infertile patients.Methods 52 patients(ob- serving group) with filling defects under HSG received hysteroscopy,and the remaining 22 patients (contrasting group) with normal hysterosalpingographic findings also received hysteroscopy with their consent.Results In- trauterine abnormalities in observing group and contrasting group confirmed by hysteroscopy were 78.8 % and 9.1% respectively,and there was statistical significance(P

The epidemic tendency of dental caries of school students over the past 15 years in China was analyzed in order to provide bases for prevention of dental caries. Data sets of boys and girls at the age of 7, 9, 12 years (deciduous caries) and 7, 9, 12, 14, 17 years (permanent caries) were collected from the series of Chinese National Surveillance on Students' Constitution and Health (CNSSCH) between 1991 to 2005, a survey that covers 30 provinces of and autonomous regions of China, with Tibet Autonomous Region and Taiwan Province excluded owing to unavailability of related data. According to their socioeconomic status, three urban regions and three rural regions (province capital must be included) were selected in each province, where its socioeconomic status and sports exercise can represent the general level of the locality. All subjects were Han students. Prevalence of deciduous and permanent caries was measured. In 2005, the prevalence of deciduous caries at 7, 9, 12 years was 52.87%, 52.04% and 9.80% in urban boys, 59.37%, 58.68% and 12.18% in rural boys, and that of permanent caries in boys at 7, 9, 12, 14, and 17 years was 2.35%, 5.63%, 13.94%, 19.05% and 21.29% in urban boys, 3.42%, 7.26%, 13.35%, 16.16%, 18.55% in rural boys, while in girls at the same age groups, the prevalence of deciduous caries was 53.53%, 49.48%, 7.92% in urban girls, 59.95%, 56.13%, 8.85% in rural girls; the prevalence of permanent caries was 3.61%, 8.99%, 19.32%, 24.75%, 28.62% in urban girls, and 3.47%, 10.65%, 17.66%, 22.52%, 24.27% in rural girls. The epidemic manifested a gradient distribution in age groups, which was closely related to region of the study population. A dramatic decreasing trend was witnessed among all sex-age subgroups in the rural groups between 1990 and 2005, and such a trend was stronger in deciduous caries than in permanent caries, however, this kind of decreasing trend was not steady, because there was bounce during some year. Although the morbidity of dental caries in China is lower than the standard set by the World Health Organization, and the prevalence of dental caries decreased from 1991 to 2005, the prospect of epidemic dental caries in China is in no way optimistic. The total population with dental caries is still very large and the prevalence decreased unstably. Therefore, financial support on school oral health care should be increased, and a national school oral health service network should be set up.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

The aim of this research is to investigate the influence of microencapsulation on the expression of the oxidative stress genes and exogenous regulation of HepG2 cells. We compared the expression of hemeoxygenase-1 (HO-1) and glutathione S-transferases-A1 (GST-A1) in HepG2 cells under different culture conditions through real-time PCR. The effects of exogenous antioxidants on cell viability and albumin levels were also evaluated through MTT assay and ELISA assay. The results showed that after culturing for 6 and 16 days, the expression levels of HO-1 in encapsulated cells were approximately 4.9 and 3.1 times higher than that of monolayer cells at the same culture period; As for the expression levels of GST-A1, they were elevated to 11.2 and 33 times of monolayer cells (P < 0.05). Accordingly, we found that NAC at 5-10 mmol/L significantly increased the viability by 40%-70% and the biosynthetic function by 20%-30% in microencapsulated HepG2 cells (P < 0.05). GSH increased the viability of the encapsulated cells by 20%-55% and the biosynthetic function by 15% (P < 0.05). In conclusion, oxidative stress exists in the microcapsules and affects genes expression. Exogenous antioxidants can prevent the inhibition effects of oxidative stress on cellular growth.

Objective To understand the current situation and the main influencing factors of hospital staffs' scientific research work in a affiliated hospital of Xinjiang,so as to provide the basis for improving awareness and level of scientific research of hospital staffs.Methods Survey using stratified random sampling method,using self-questionnaire research capacity factors questionnaire, to investigate the status of project leaders' research capacity in a affiliated hospital of Xinjiang.Using frequencies and relative number described ability to research,using x2 to compare research level among the various metrics.Scientific research levels' multivariate analysis using Ordinal Logistic Regression Analysis.Results regarding of scientific research,low level of 14 people,accounting for 4.9％,the middle level of 158 people,accounting for 55％,a high level of 115 people,accounting for 40.1％.Univariate analysis showed that age,length of service,education level,job title,whether master instructor it is,the research team,the situation of foreign training and learning opportunities,foreign academic session (times),support from leadership and family,non-working time for research,the total research funding (ten thousands yuan),discipline level have impact on the level of scientific research work.Ordinal Logistic regression analysis showed that age,length of service,educational level,whether master instructor it is,the total research funding (ten thousands yuan),discipline level are the main factors on level of scientific research work.Conclusions The scientific research level needs to be further improved,the level of scientific research is affected by many factors.

Adipose-tissue mesenchymal stem cells, is one kind of multipotent stem cells, can differentiate into adipogenic, osteogenic, chondrogenic, myogenic cells and so on in vitro and in vivo. Human adipose tissue is plentiful, easily harvested in large quantity with little patient discomfort. Adipose-tissue derived mesenchymal stem cells may be an alternative stem cell source for mesenchymal tissue regeneration and engineering without ethical consideration of embryonic stem cells and severe pain resulted by bone marrow procurement. The research work on adipose-tissue mesenchymal stem cells and future clinical perspectives were reviewed.
