AIM　To study the chemical components of the root of Clematis chinensis. METHODS Various chromatographic techniques were used to separate and purify the components. Their structures were determined on the basis of spectral and chemical evidence. RESULTS　Two compounds were isolated and elucidated as: clemaphenol A (I) and dihydro-4-hydroxy-5-hyroxymethyl-2(3H)-furanone (II). CONCLUSION Compound I and II are new compounds.

To explore the role of Human papillomavirus (HPV) in mammary carcinogenesis, the expression of the HPV-16, iNOS, P53 and hTERT proteins in breast carcinomas and their relationships were investigated. 52 samples of breast cancer and 16 samples of benign breast tumors were assayed using the immunohistochemical SP method for detection of protein expression levels. The expression of HPV-16, iNOS, P53 and hTERT proteins in a mammary carcinoma was 44.2%, 57.7%, 63.5% and 59.6% respectively, which was significantly greater than the corresponding levels in the benign group. The expression of iNOS, P53 and hTERT was correlated with the presence of an HPV-16 infection in a mammary carcinoma (P<0.05). The connection between these events might also involve the iNOS, mutated type P53 and the hTERT protein.

0.05). The stepwise regression analysis showed that the logarithm of the duration of residual gas had a parallel relationship with the gas volume under the hemi-diaphragm 24 hours after operation(r=0.616,P=0.006),a negative correlation with the duration of pneumoperitoneum (r=-0.228,P=0.014), and no correlation with patients’ age,body weight,height,operation time and gas volume consumed. Postoperatively, 26 patients reported postoperative shoulder pain. The shoulder pain VAS scores were significantly increased with the increasing of CO_2 pressure in the three groups (F=9.635, P=0.000). The shoulder pain VAS scores had a parallel relationship with the gas volume under the right hemi-diaphragm 24 hours after operation (r=0.333, P=0.005) and the duration of residual gas (r=0.296, P=0.014). Conclusions The CO_2 should be removed as thoroughly as possible at the end of operation to reduce the absorption of residual gas. The different CO_2 pressures of pneumoperitoneum have little effects on the volume of residual CO_2 24 hours after operation and the duration of residual gas. The shoulder pain following LC, will be aggravated with the increasing of pneumoperitoneum pressure. The over-stretching of the diaphragmatic fibers due to insufflation is the main cause of shoulder pain.

Objective To establish a determination method of ferulic acid in Jianpibuxue tablets.(Methods)HPLC was used with Lichrospher C_(18)(4.6mm?250mm,5?m) as the column.The mobile phase was a mixture of acetonitrile-0.378mol/L acetum(30∶70) and in a flow rate of 0.8mL/min;The detective wavelength was 321nm;Column temperature was room temperature and the injection quantity was 10?L.(Results)Ferulic acid in samples was well separated.The linear range was 1.0-10.0mg/L(r=0.9996).The average recovery was 99.8% and RSD was 0.26 %(n=6).Conclusion This method can be used for quality control of ferulic acid in Jianpibuxue tablets.

Objective To investigate the effects of low-dose X-ray radiation on pituitary gland area to treat benign prostatic hyperplasia.Methods Using the linear-accelerator 6mV X-ray to radiation on pituitary gland area,1.2Gy/f,2 times/week,total dose was 4.8～6.0Gy.The uro-flow rate and residual urine volume were measured.Results The immediate effect was 77.5%,the 1-year effect rate was 70%.After treatment,the uro-flow rate was significantly increased(P

Systems biology, which includes genomics, proteomics, transcriptomics and metabolomics, is an integration of system theory and biology. It studies the life phenomena with thinking method of systems theory. And it provides an important methodological basis and technical conditions for recognizing syndrome of traditional Chinese medicine (TCM) and mechanism of therapeutic effect from multiple disciplines and perspectives. Systems biology is similar to the core idea of TCM system and holism concept. Therefore, systems biology can be used as a platform and pivot of non-alcoholic fatty liver disease (NAFLD) in modern TCM study. Systems biology will accelerate the modernization research of TCM in the prevention and treatment of NAFLD. It will also provide new ideas and methods for TCM study on NAFLD.

Objective To investigate the estrogen-like effects of Epimedium extractive.Methods By using the uterus growth test in mice and test of MCF-7 proliferation and adding estrogen receptor antagonist Icariin,we evaluated the estrogenic effects of Epimedium and Icariin and the possible mechanism.Results Epimedium and Icariin increased significantly the uterus coefficient in mice from 0.097?0.008 to 0.156?0.018 and 0.152?0.016,respectively;the weight increased significantly from(18.9?1.3)g to(19.8?1.3)g and(20.03?1.3)g(P

Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is one of the most frequently occurring cancers. Hepadnaviral DNA integrations are considered to be essential agents which can promote the process of the hepatocarcinogenesis. More and more researches were designed to find the relationship of the two. In this study, we investigated whether HBV DNA integration occurred at sites of DNA double-strand breaks (DSBs), one of the most detrimental DNA damage. An 18-bp I-SceI homing endonuclease recognition site was introduced into the DNA of HepG2 cell line by stable DNA transfection, then cells were incubated in patients' serum with high HBV DNA copies and at the same time, DSBs were induced by transient expression of I-SceI after transfection of an I-SceI expression vector. By using nest PCR, the viral DNA was detected at the sites of the break. It appeared that integration occurred between part of HBV x gene and the I-SceI induced breaks. The results suggested that DSBs, as the DNA damages, may serve as potential targets for hepadnaviral DNA insertion and the integrants would lead to widespread host genome changes necessarily. It provided a new site to investigate the integration.

Objective To observe the toxic effect of the mixture of organophosphorus pesticide (MOP) on maternal rats and on the growth and development of their offspring. Methods Totally 40 Sprague-Dawley pregnant rats were randomly divided into three MOP dose groups and one control to which their offspring would be assigned. The experimental dosage of MOP and distilled water were administered orally starting on gestation day 15 and continued for 35 days. The physical development indices and the learning ability of F1 rats were measured during lactation. The pathological changes of uterus and liver of F0 rats were observed after weaning, while the weight ratio of uterus and some viscera to body of the F1 were examined. Results There were obvious changes of uterus and liver in the high-dose group of F0. The body-weight accretion of the F1 in high-dose group was obviously lower than that in control group (P<0.05). Some of the MOP F1 rats development indices delayed significantly (P<0.05), the learning ability decreased obviously, and the time of setting up memory prolonged (P<0.05). The ratio of the uterus weight to body-weight in the F1 MOP groups was significantly higher than that in control group (P<0.05). Conclusion The experiment doses of MOP are proved to have significant reproductive toxicity on perinatal rats.
