Objective: To investigate the changes of the small G protein RhoB expression in scalded rat livers and heat-stressed human prostate cancer cell line PC-3, so as to discuss the influence of heat stress on expression of RhoB in vitro and in vivo. Methods: Third degree burns of 30% total body surface area (TBSA) model was established with SD rats on the back. The expression of RhoB mRNA and protein in the liver was determined by RT-PCR and Western blot 2 h, 4 h, 8 h and 16 h (n=6) after scalding; the liver tissues of normal rats were taken as control (n=6). PC-3 cells were allowed to recover for 0.5 h, 1 h, 2 h, 4 h and 8 h in a cellular heat stress model and the expression of RhoB in mRNA and protein were determined by RT-PCR and Western blot, respectively; untreated PC-3 cells were taken as control. Results: The expression of RhoB mRNA in the livers peaked 4 h after scalding, being about 3.2 folds that of the control group (P<0.01); the expression began to decline 8 h after scalding. The expression of RhoB protein peaked 8 h after scalding, significantly higher than that of the control (P<0.01). RhoB mRNA level began to increase 2 h after heat stress treatment and peaked at 4 h, being about 2. 8 folds that of the control (P<0.01). The expression of RhoB protein reached its maximum at 8 h after heat stress treatment (P<0.01). Conclusion: Heat stress can up-regulate the expression of RhoB mRNA and protein in vivo and in vitro.

Objective To establish a new method for the determination of chromium (Ⅵ) in printing and dyeing wastewater. Methods A combined technique was employed for the determination of chromium (Ⅵ) by flow injection on-line separation and preconcentration on a micro column packed with alumina(acidic form) and inductively coupled plasma-atomic emission spectrometry (ICP-AES).The effect of acidity,concentration of eluent and coexistence ion on separation and enrichment was detected.Results The detection limit was 0.72 ?g/L.The LOQ was 2.38 ?g/L.RSDs were 1.45%～2.12%.The recovery rates were 96.0%-104.0%.The concentration enhancement of chromium (Ⅵ) was 10 times for 45 s sample loading.Analytic frequency was 33 samples one hour. Conclusion This method is sensitive,rapid and applicable to the determination of chromium (Ⅵ) in dyeing wastewater.

Objective: To study the dosage application of herbs in class formulas of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy (Taiping Huimin Hejiju Fang), Essential Recipes for Emergent Use Worth A Thousand Gold (Beiji Qianjin Yao Fang) and Records of Approved Cases of Ancient and Recent Times (Gujin Luyan) and their actions on depression. Method: According to the dosage proportion of different herbs in the three formulas in the three books, two methods were adopted in terms of decocting different herbs separately and mixing them thereafter(group of decocting separately) as well as extracting after decocted all the herbs together (group of decocting together). Classical anti-depression mice models--forced swimming and tail suspending experiments were observed. The data of immovability time of mice were analyzed by statistics. Result: All the class formulas of KaixinSan which have the same medication but different proportion in the three medical books can reduce the immovability time of mice in forced swimming and tail suspending experiments. But the action of KaixinSan recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy was prominent, and the action of the group of decocting together was superior to that of separated decocting. There was significant difference between the group of decocting together in low dosage and the controlled one (P

In recent years a number of qualitative research methods have gained popularity within the health care arena. Despite this popularity, different qualitative analysis methods pose many challenges to most researchers. The present paper responds to the needs expressed by recent Chinese medicine researches. The present paper is mainly focused on the concepts, nature, application of framework analysis, especially on how to use it, in such a way to assist the newcomer of Chinese medicine researchers to engage with the methodology.
