Objective To discuss the effect of small needle knife therapy on collagensⅠ and Ⅲ in the hypertrophic scar tissues that was subcutaneously transplanted into nude mice. Methods Six samples of human hypertrophic scar tissues without cuticle were subcutaneously transplanted into the back of 24 nude mice to create the animal models of hypertrophic scar. Ten days after of the operation,the mice were divided into control,0.1 mg/ml triamcinolone,0.2 mg/ml triamcinolone,and small needle-knife groups with 6 mice in each. Specimens of the scar tissues were collected in 14 days for immunohistochemistry to detect the collagen Ⅰ and Ⅲ. Results In all the groups,collagens Ⅰand Ⅲ distributed extensively in the cytoplasm of fibroblast and tissues. Image analysis showed that the concentration of collagens Ⅰand Ⅲ in 0.1 mg/ml and 0.2 mg/ml triamcinolone groups were significantly lower than those in the control (0.09?0.03,0.11?0.05 and 0.12?0.02,0.11?0.01 vs. 0.17?0.04,0.19?0.03,P0.05). Conclusions Small needle-knife therapy can reduce the concentration of collagens Ⅰand Ⅲ in transplanted hypertrophic scar tissues in nude mice.

Objective To observe liver functional lesion caused by combination chemotherapy containing or not containing oxaliplatin. Methods Data from 42 patients with liver functional lesion caused by chemotherapy between March 2005 and October 2007 were analyzed. All patients were diagnosed through histology or cytology detection and received chemotherapy only. Different drugs were. admitted,based on different tumors. Before chemotherapy, each patient had normal liver function without liver lesions such as liver metastasis, Hepatitis B and C, hepatic cirrhosis, etc. Furthermore, 22 received FOLFOX-4 in containing oxaliplatin group while the remaining 20 received chemotherapy excluding oxaliplatin. When liver functional lesion without the influence of any liver protectant was first observed, ALT, AST, TBIL, DBIL, IBIL, ALP, GGT and the WHO criteria of liver toxicity were analyzed. T test and Wilcoxon rank sum test were used for data analysis. Results All together 90 cycles, median 2.14 cycles, were given. According to WHO criteria of liver toxicity, 13 cases were in grade O, 21 in grade Ⅰ, 7 in grade Ⅱ, and 1 in grade Ⅲ. ALT and AST were significantly high after chemotherapy(P <0.05). Moreover, ALT and AST were significantly higher in containing oxaliplatin group than non oxaliplatin group after chemotherapy(P <0.05). Chemotherapy had no influence on bilirubin. The population distribution of accumulative chemotherapy cycles and WHO criteria of liver toxicity was similar between two groups. Conclusion Before the intervention of liver protectant, combination chemotherapy containing oxaliplatin is more likely to have liver functional lesion than other chemotherapy without oxaliplatin. It mainly presents an increase in transaminase.

Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".

To systematically evaluate the clinical efficacy and safety of compound Danshen injection in treating hypoxic-ischemic encephalopathy (HIE) of newborns. Computer retrievals were made in PubMed, Embase, Cochrane Library, CBM, CNKI, VIP and China info (before May 2014) and relevant literature references, and manual retrievals were made for journals and conference papers, in order to collect randomized or semi-randomized controlled trials concerning compound Danshen injection in the treatment of neonatal HIE. The quality of included references was evaluated according to literatures recommended by Cochrane Handbook. RevMan 5. 3 software was applied in the statistical treatment. Finally, a total of 13 randomized controlled trials were included, covering 1,211 patients (including 639 patients in the compound Danshen injection-treated group and 572 patients in the control group). Meta-analysis results showed that the routine treatment combined with compound Danshen injection can improve the treatment efficiency of neonatal HIE [RR = 1.28; 95% CI (1.21-1.36)], reduce the mortality rate [RR = 0.42; 95% CI (0.23-0.75)] and the incidence of long-term neurological sequelae [RR = 0.48; 95% CI (0.35-0.65)], with statistical differences. No fatal side effect was observed in all of included trials. So far, limited evidences in this study proved that the application of compound Danshen injection in the treatment of neonatal HIE can enhance the clinical efficiency. However, because of the low quality of the included trials, more well-designed and large-scale multi-center randomized controlled trials shall be made in the future.

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.
