Results From 2010 to 2012, drug possession rate of TCM injections in our hospital was 4.07%-4.47%;the amount of medication accounted for 10.50%to 12.69%of the amount of all drugs;the annual growth rate increased significantly, among which TCM injections used for removing blood stasis took the lead;frequency of drug use rose annually;medication synchrony in 3 years indicated that daily expensesof Shenkang Injection, Aidi Injection, salvianolateinjection, safflor yellow sodium chloride injection and other TCM injections were on the high side. Conclusion From 2010 to 2012, TCM injections in the clinical application in our hospital were of relatively high frequency, and the TCM injections used for removing blood stasis took the lead. Daily expenses of TCM injections drugs were on the high side and there may be unreasonable application.
6.Study on the effects of bacterial collagenase on wound healing
Chinese Journal of Emergency Medicine 2010;19(5):476-478
Objective To study the role of bacterial collagenase in wound healing with observing capillary neovascularization, epidermis regeneration and collagen fiber reparation in vivo. Method A total of 28 New Zealand rabbits were made into models of superficial soft tissue trauma and divided into two groups. In the experimental group, the right limbs of rabbits were traumatized intentionally in the same length and depth, and their wounds were treated with bacterial collagenase liquor 133 MIU/mL, and the wounds were sutured. Similarly, in the control group, the left limbs of the rabbits were modeled in the same way and their wounds were managed with physiological saline instead and closed. Their wounds were observed continually 1, 2, 3, 5, 7, 10 and 14 days after traumatized. Data were analyzed statistically by using One-way ANOVA, LSD-test, and Wilcoxon rank test. Results There were no significant differences in capillary neovascularization and epidermis regeneration between two groups ( F = 0.12, P = 0.740 and F = 0.95, P = 0.33, respectively), but significant difference in collagen fiber reparation was found between two groups (F = 6.63, P = 0.01). Conclusions In the progress of wound healing, bacterial collagenase can improve the collagen fiber reparation without effects on the new capillary vasculogenesis and epidermis regeneration. The bacterial collagenase does not play a positive role in wound healing.
7.HSP40 and HSP70 inhibit the accumulation and toxicity of mutant huntingtin in N2a cells
Acta Anatomica Sinica 2009;40(4):517-521
Objective To study the effect of heat shock protein 40(HSP40) and heat shock protein 70(HSP70) on the aggregate formation of mutant huntingtin (htt) and its toxicity in N2a cells. Methods The effect of the over-expression of HSP40 and HSP70 alone or co-over-expression of them on aggregate formation of transfected mutant htt (containing 150 glutamine repeats, 150Q) in N2a cells was detected by fluorescence microcopy and Western blotting. Cell viabilities were detected by MTT assay. Reactive oxygen species (ROS) production was detected by colorimetric method. Results The over-expression of HSP40 and HSP70 alone, especially the co-over-expression of them, dramatically decreases the formation of 150Q htt aggregates in N2a cells. The numbers of aggregates in each group are as follows ( n = 1 000): about 50% in the group of 150Q htt-expressing alone, about 12% in the group of over-expression of HSP40, about 15% in the group of over-expression of HSP70, about 5% in the group of co-over-expression of HSP40 and HSP70. The result of MTT assay shows that the over-expression of HSP40 and HSP70 alone, especially the co-over-expression of them, dramatically increases cell viabilities ( P<0.01, n =3) and reduces the production of ROS ( P<0.01, n =3). Conclusion HSP40 and HSP70 can increase cell viabilities of 150Q N2a cells via inhibiting the aggregates formation of mutant huntingtin and reducing oxidative stress.

International Journal of Traditional Chinese Medicine 2015;(1):52-55
Objective To investigate the effects of Gynostemma Pentaphyllum on serum markers of liver fibrosis in cholesterol-induced non-alcoholic fatty liver disease (NAFLD) in rabbits. Methods Forty adult male white rabbits were randomly divided into a normal control group, a model group, a treatment group and a simvastatin group, with 10 rabbits in each group. NAFLD was induced with a high-cholesterol diet. After modeling, the rabbits in the treatment group were intragastrically administrated with Gynostemma Pentaphyllum 5 mg/(kg?d), the simvastatin group with simvastatin 5 mg/(kg?d), and the model and normal control groups with the equal volume of distilled water for 9 weeks. The serum levels of total cholesterol (TC) and triglyceride (TG), the serum inflammatory maker C-reactive protein (CRP), the serum markers of liver fibrosis such as hyaluronic acid and laminin (LN), and the TG level in the liver tissue were detected. Results Compared with the normal control group, the serum levels of TC (60.50 ± 9.77 mg/L vs.1.30 ± 0.44 mg/L), TG (1.72 ± 0.61 mmol/L vs. 0.85 ± 0.39 mmol/L), CRP (256.79 ± 30.78 mg/L vs. 8.71 ± 1.41 mg/L), HA (798.8 ± 69.4 ng/ml vs. 121.2 ± 6.8 ng/ml),LN (964.8 ± 62.8 ng/ml vs. 142.4 ± 12.2 ng/ml) in the model group were increased significantly (all P<0.01). Compared with the model group, the serum levels of TC (36.44 ± 6.57 mmol/L vs. 60.50 ± 9.77 mmol/L), TG (1.31 ± 0.39 mmol/L vs. 1.72 ± 0.61 mmol/L), CRP (68.77 ± 10.78 mg/L vs. 256.79 ± 30.78 mg/L), HA (420.8 ± 60.2 ng/ml vs. 798.8 ± 69.4 ng/ml), LN (449.8 ± 56.6 ng/ml vs. 964.8 ± 62.8 ng/ml) and the TG level in the liver tissue (0.52 ± 0.10 mmol/L vs. 0.77 ± 0.08 mmol/L) in the treatment group were decreased significantly (all P<0.01). The TG level in the liver tissue in the treatment group was significantly lower than that in the simvastatin group (0.52 ± 0.10 mmol/L vs. 0.59 ± 0.09 mmol/L;P<0.05). There were no significant difference in the serum levels of TC, TG,CRP,HA and LN between the treatment group and the simvastatin group (all P>0.05). Conclusions Gynostemma Pentaphyllum may regulate lipid metabolism, alleviate inflammation, and decrease serum markers of liver fibrosis, and might protect against liver fibrosis in rabbits with NAFLD.
