Objectives: Observe the effects of acupuncture on obese SD rats fed by self-prescribed high calorie diet. Methods: The model group were male SD rats fed by self-prescribed high calorie diet, while the control group were male SD rats fed by common roughage. After acupuncture, the changes of some indexes were observed such as eating and drinking amount,body weight,length, Lee index,fattiness in groin and circumrenal areas, TG,TC,BG levels in blood etc. Results: The obesity was defined as the average body weight of the model group was 20% heavier than the average body weight in the control group. And the obesity ratio was 56%. The indexes were changed in different degrees with statistic significance after one period of treatment. Conclusions: Over-nutrition is one of the causes of obesity. Our high calorie feed for obese rat is reasonable. Acupuncture has obvious therapeutic effects for simple obesity.

Objective To explore the role of human urinary trypsin inhibitor(UTI) in severe acute pancreatitis (SAP). Methods UTI was highly purified from the urine of patients with acute pancreatitis by column chromatography. SAP models were established by injection of 5% sodium taurocholate(NaTc) at dose of 0.1 ml/100 g weight under pancreatic capsule. The interleukin 6(IL 6) level in each group was measured by ELISA. Results ① The highly purified UTI with high yield was harvested. ② SAP models were established successfully. ③ The level of IL 6 in SAP group was significantly higher than that in NC, but in UTI group, the increase was not obvious. Conclusion The alleviating effect of UTI on the pathological damage degree in rats with SAP is related to the inhibitive effect of UTI on the expression of IL 6.

The roots of Pittosporum glabratum Lindl. (Pittosporaceae) have been used as a folk medicine for the treatment of rheumatic arthritis, insomnia and hypertension. Only a few chemical or biological studies on P. glabratum have been reported. As part of our ongoing phytochemical research on this plant, four compounds were isolated. Their structures were identified as 3beta, 6beta, 19alpha, 21alpha, 24-pentahydroxy-12-en-28-oleanolic acid (1), 3-O-beta-D-glucuronopyranosyl-28-O-beta-D-glucopyranosyl siaresinolic acid (2), 3, 4, 5-trimethoxyphenyl-1-O-beta-D-(5-O-syringoyl)-apiofuranosyl-(1 --> 6)-beta-D-glucopyranoside (3) and 3, 4, 5-trimethoxyphenol-1-O-beta-D-apiofuranosyl-(1 --> 6)-beta-D-glucopyranoside (4) on the basis of physical evidence and spectroscopic analysis. Among them, compound 1 is a new triterpenoid, and compounds 2-4 are isolated from the genus Pittosporum for the first time.

·AIM: To evaluate the function of primary human corneal endothelial cells(HCEC) serving as immunological cells. ·METHODS: Expression of HLA-DP, -DQ, -DR, CD40, CD80, and CD86 was determined by immunohistochemical methods. Meanwhile, purified peripheral blood mononuclear cells(PBMC) were cocultured with primary HCEC which were pre-treated with and without γ-IFN respectively; activation of lymphocytes was determined by FACS analysis.·RESULTS: In coculture system, T lymphocyte was activated by primary HCEC, HLA-DP, -DQ, -DR and CD40 expression were increased by γ-IFN induction. Costimulatory molecular CD80 was shown on the endothelial cells. ·CONCLUSION: Primary HCEC were assumed to be involved in the corneal transplantation rejection process as potential antigen presenting cells(APC).

To explore the influencing factors of major birth defects.The children of 0 -3 years and their mother from six different districts were surveyed from November 2009 to December 2009.The incidence rate was 134.27/10 000 (493/36 716)in 6 counties. And the first five birth defects were as follows:congenital heart disease,neural tube defects,cheilopalatognathus,polydactylia and hypophrenia.The risks and protective factors of the first 5 birth defects were different.Anamnesis of birth defects and defective children from relatives,multiple pregnancy & birth and intake of antipyretic analgesics during pregnancy were the common risk factor for the first 5 birth defects.The key points for the prevention of birth defects are to reinforce the pre-pregnancy guidance,the screening and evaluation of risk factors and disease prevention during pregnancy.

Objective To evaluate the characteristics and clinical suitability of the ArcCHECK diode array for volumetric-modulated arc therapy (VMAT) verification.Methods The intrinsic sensitivity,short and long term reproducibility,dose and dose rate dependence,dose per pulsed dependence,field sizes dependence and directional response of the diodes were measured.The results of the diodes were compared with the measurement results of an ionization chamber and calculated results of treatment planning system.Gamma index was used to analyze the dose difference between the calculation and measurement for random selected 211 verified VMAT plans.Results The ArcCHECK performed well for all tests except directional dependence,which varies from a minimum of-3.9% (seen only when the beam was incident on the diode at 180°) to a maximum of 7.7% (approximately at 255°).Average gamma analysis passing rates with 3 mm/3% for 113 nasopharyngeal cancer,48 cervical cancer and 50 rectal cancer patients VMAT plans were 93.5%,95.7% and 97.5%,respectively,statistical significance has been found between either two of the groups (t=-12.69-4.88,all P< 0.01).Conclusions With proposed calibration method,the ArcCHECK diode array is very suitable for VMAT pretreatment verification,the complexity of VMAT plan is the main factor affecting the passing rate.

To investigate the impact of respiratory movement to determine the target volume on cone beam CT (CBCT) for lung tumor, we used CIRS dynamic thorax phantom (Model-CIRS008) to simulate the sinusoidal motion of lung tumor. With a constant amplitude, the ratio of the time of near-end-expiratory and near-end-inspiratory (E/I) changed when it was scanned with CBCT. We analyzed the contrast changes of target by extracting the CT value of each pixel on the center line of the target movement direction. The targets were contoured with region growing method and compared with the motion volume generated by the tumor trajectory method. The result showed that the contrast of near-end-expiratory increased and the contrast of near-end-inspiratory decreased with increasing E/I. The contoured volume generated by region growing method decreased with increasing E/I. When E/I = 4, the amplitude A = 1 cm, diameter of 1 cm and 3 cm target volumes were reduced by 48.2% and 22.7%. The study showed that CBCT was not suitable to be used to accurately determine the range of lung tumor movement. The internal target volume (ITV) may be underestimated in CBCT images.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.
