Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.

Objective: To evaluate the effect of propofol with different concentrations on the expression of inflammatory mediators of interleukin and tumor-necrosis factor-α (TNF-α) by stimulating the mouse primary monocytes and human monocytic cell line with lipopolysaccharide (LPS) and also discuss the effect of propofol on the secretion of inflammatory mediator and its possible molecular mechanism. Methods: The mononuclear cells of mouse spleen were separated and then purified to obtain the primary monocytes. The dose-effect relationship of production of pro-inflammatory cytokines by monocytes which were stimulated by LPS, namely the monocytes were stimulated by the dose of 0-500 ng/mL for 24 h. ELISA was employed to detect the concentration of IL-6, IL-8 and TNF-α. The effect of propofol on the secretion of above pro-inflammatory cytokines by the monocytes was observed. Cells were divided into the control group, the 0.1% DMSO group, the LPS group and the treatment group with LPS + different dose of propofol (propofol 1-100 μg/mL). ELISA was employed to detect the concentration of IL-6, IL-8 and TNF-α. The change in the expression of important signaling molecules in Toll-like receptor and NF-κB signaling pathway was detected after THP-1 cells were treated with propofol. Results: The concentration of TNF-α was (3. 863 ± 153) pg/mL after 12 h of stimulation by LPS and then its concentration was decreased gradually. But the concentration of IL-6 and IL-8 was relatively high after 24 h of stimulation by LPS, (5. 627 ± 330) pg/mL and (1. 626 ± 200) pg/mL, respectively. The propofol could inhibit the expression of IL-6, IL-8 and TNF-α caused by LPS. After the intervention treatment of 50 μg/mL propofol, the concentration of IL-6, IL-8 and TNF-α was significantly decreased (P < 0.01). Conclusions: The propofol can inhibit the expression of TLR-4 and NF-κB to inhibit the activation of p38 and the expression of pro-inflammatory cytokines.

Danggui, Agelicae Sinensis Radix, is a widely used Chinese herb to enrich blood, but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid, ligustilide, polysaccharides, etc. A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity (EBB) for the quality assessment of Danggui raw materials. Danggui sample was first extracted with ethanol and water, respectively. Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment. The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophospharmide and phenylhdrazine hydrochloride. The quantity of red blood cell was chosen as EBB marker. Cyclosporine A was chosen as a control substance. EBB in analytes was quantified by the amount reaction of parallel line analysis (3, 3') method. The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid. The analytes showed the significant EBB (P < 0.05). The correlation coefficient was 0.9984 (n=5) between the amount of cyclosporine A (0.035-0.56 g x kg(-1)) and the increased number of red blood cell. The relative standard deviation (RSY) on the amount of EBB was estimated to be 6.15% (n = 6) by six replicated tests, and the confidence limit rate was 26.68% (n = 6). Five Danggui samples, which were collected from different cultivation areas with various morphological characters, showed the variety of EBB in the range of 21.95-44.16 U x g(-1). It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials, and is therefore suitable to assess its quality.

OBJECTIVETo estimate the number of drug users in Hongjiang, Hunan and to develop strategy for drug reduction in the future.
METHODSTwo capture-recapture methods were used to estimate the numbers of drug addicts. Random stratified sampling survey was used to verify the optimum allocation. The first capture-recapture method (CR1) referred to the number from optimum allocation random stratified sampling survey conducted in the communities and the number from local Public Security Bureau list being the second capture. The second capture-recapture method (CR2) referred to the collection of records in the detoxification unit with an interval of 4 months. The estimated number was calculated under Seber's adjustment formula. Face to face interview was carried out during the optimum allocation random stratified sampling survey process.
RESULTSOf 1388 interviewed in the communities, 24 (1.73%) were identified as drug addicts under the optimum allocation random stratified sampling survey. When the figure 1.73% was applied to the total population (72,709) in Hongjiang, the result yielded an estimation of 1258 drug addicts. The estimated numbers of CR1 and CR2 were 904 and 1069 respectively. However, the number was 1.3 to 1.6 fold higher than the reported number (687) by local Public Security Bureau.
CONCLUSIONThe capture-recapture method seemed a better method in estimating the number of drug addicts.
