OBJECTIVE:To put forward some suggestion to improve drug bidding system in China.METHODS:The process of drug bidding system reform and its common problems were analyzed.Game theory and information asymmetry theory were adopted to analyze the root of the problems and to put forward suggestions.RESULTS:Governments indiscriminately expanded the goals of bidding policy and strengthen price factor.They neglected important steps such as logistics distribution.Current single evaluation system can not count the medication order exactly.Delayed received payment of medical institution resulted in many problems of drug purchase.CONCLUSION:Centralized drug bidding system should be improved and enhanced.It also should be connected with relevant medical system reform to standardize drug circulation channels,reduce drug price and reduce the burden of patient.

Objective To investigate the effects of estrogen on the expression of phosphofructokinase muscle-specific isoform(PFK-M) in genioglossus of chronic intermittent hypoxia(CIH) rats. MethodsFifty male SD rats were randomly divided into five groups: the normal control group(NC), the chronic intermittent hypoxia group(CIH), and three doses of estrogen plus hypoxia groups(LE, ME, HE). Rats in the latter four groups were used to build CIH models(8 h/d, 5 weeks). In the mean time, rats in the latter three groups were injected with three dose levels of estrogen(0. 1, 0.2, 0.3 mg/kg), and rats in NC and CIH groups were injected with sterile olive oil as control At the end of the treatment, the genioglossus was isolated and quickly removed. The mRNA levels of PFK-M were determined by real-time RT-PCR and the protein content of PFK-M was detected by Western blotting analysis. ResultsPFK-M mRNA and protein in CIH group (2. 144±0.260, 0.875±0.025) were both higher than those (1.000±0.259, 0.413±0.013) in NC group (P ＜0. 05). The expression of PFK-M mRNA in LE, ME and HE groups were 1. 424 ±0. 193, 1. 395 ±0. 251and 1.310 ±0. 094, respectively. The expression of protein in LE, ME and HE groups were 0. 638 ±0. 015,0. 576 ±0. 017 and 0. 505 ±0. 021, respectively. Compared with CIH group, the expression of PFK-M mRNAand protein in LE, ME and HE groups were all inhibited significantly(P ＜0. 05). Among the three treatment groups, decreased protein content of PFK-M was observed only in HE group when compared with LE group (P＜0.05), but no significant difference was detected in the expression of PFK-M mRNA. Conclusions CIH exposure could increase the expression of PFK-M mRNA and protein in rat genioglossus, while estrogen administration could dose dependently inhibit the overexpression.

Objective To investigate the expression and clinical significance of peroxisome proliferator activated receptor γ(PPARγ)in bladder urothelial cancer tissues.Methods Parafflin‐embeded specimen of bladder urothelial cancer tissues from 50 cases and normal tissues near the bladder urothelial cancer from 5 cases were harvested from the Pathology Department of the Renmin Hospital of Wuhan University between 2006 and 2009.Those cases had complete pathological and clinical data.The ex‐pression of PPARγ was detected by immunohistochemical SP method.Quantitative analysis of the PPARγ was measured by high definition pathological graphics context report system (HPIAS‐1000).One‐way analysis of variance and SNK (q)tests were used to analyze the mean density and the positive area rate of the immunohistochemical results.All data were processed by SPSS 13.0.Results The expression of PPARγwas significantly higher in bladder urothelial cancer tissues than in para‐carcinoma tis‐sues(P<0.05).Correlation between expression of PPARγ with TNM stag of bladder urothelial cancer was as follows :Positive rate of PPARγin the tissues with primary tumor size ≥3 cm was 72.4% ,significantly higher than 33.3% in the tissues with tumor size <3 cm(P<0.05);positive rate of PPARγin the cases with lymph node metastasis was 72.7% ,significantly higher than 46.4% in the cases without lymph node metastasis(P<0.05);positive rate of PPARγin patients at stage T3‐4 group was 75.0% ,significantly higher than 41.9% and 45.5% in patients at clinical stage T1 and T2(P<0.05);positive rate of PPARγin patients with poor differentiation was 68.2% ,significantly higher than 42.9% in patients with high or middle differentiation group(P<0.05).Conclusion PPARγ plays an important regulating role in the onset and progress of bladder urothelial cancer ;PPARγexpression level was correlated with primary tumor size ,pathological types and differentiation degree ,lymph node me‐tastasis and clinical stage.This result suggested that PPARγ was closely correlated to metastasis of bladder urothelial cancer.

Objective: To study the anti inflammatory, antipyretic and analgetic actions of Kangleifengshi capsules. Methods: The anti inflammatory action was observed by adjuvant arthritis and other inflammatory models. The antipyretic action was surveyed by pyretic rat induced by yeast. The analgetic effect was tested by sprain mice. Results: The experiments proved that the capsule has significant preventing and treating effects on rat adjuvant arthritis, strong inhibition on many kinds of inflammatory models, antipyretic action on pyretic rat induced by yeast and notable angalgetic action on sprain mice induced by acetic acid. Conclusion: Kangleifengshi Capsules has better anti inflammatory, antipyretic and analgetic effects.

Objective To investigate the differences of curriculum designs for undergraduate nursing majors among different TCM colleges and universities;To provide evidence for the development of the accreditation standards for academic quality of baccalaureate degree program in TCM colleges and universities which can be used as the standards for teaching reform. Methods Cultivating plans of 20 TCM colleges and universities for undergraduate nursing majors were collected. Current status and deficiency in curriculum design were obtained through comparative study and statistical analysis.Results The course names were lack of standardization;proportion of Chinese and Western medicine related courses were unreasonable;theoretical and practice teaching were irrelevant;optional courses were greatly inconsistent and irrational. Conclusion The further reform of the curriculum design for the undergraduate nursing majors in TCM colleges and universities is in urgent need, which can be standardized by developing the accreditation standards for academic quality of baccalaureate degree program in universities of Chinese Medicine.

Objective:To study the antibacterial activity of sanguisorba tannin extract in vitro and its mechanism in the antibacterial effect on staphylococcus aureus. Methods:The antibacterial effect of sanguisorba tannin extract was studied by an Oxford-cup method and a tube double dilution method. With staphylococcus aureus as the tested bacteria, extracellular alkaline phosphatase (AKP), potassium ion, soluble protein and T-ATPase were determined. The changes in protein bands and the cell ultrastructure were respectively observed by SDS-PAGE and TEM to illustrate the antibacterial mechanism. Results:The results showed that sanguisorba tannin extract was effec-tive against the gram-positive bacteria, while the effect against the gram-negative bacteria was weak. After staphylococcus aureus was trea-ted with sanguisorba tannin extract, the contents of alkaline phosphatase (AKP), potassium ion, soluble protein, DNA, RNA and the other large molecules were increased obviously when compared with those in the control group. The concentrations of intracellular and ex-tracellular ATP were significant changed. DS-PAGE showed that staphylococcus aureus treated with sanguisorba tannin extract had no pro-tein band formation. TEM showed that the cell integrity was damaged. Conclusion:Sanguisorba tannin extract shows strong antibacterial activity, which can change the cell membrane permeability and damage the cell integrity.
