Objective To evaluate the clinical efficacy of integration of traditional Chinese and western medicine (ITWM) or pure western medicine on the patients with immune thrombocytopenia (ITP). Methods Randomized controlled trials (RCTs) on ITWM treatment of ITP were searched in PubMed, EMBASE, Wanfang database, CBMDisc, CNKI and VIP. Quality of the RCTs was evaluated strictly, and statistical analysis was performed with Cochrane Collaboration’s RevMan5.1.7 software. Results Twenty-two trials involving 1527 patients were included. The results of Meta-analysis showed that the ITWM treatment of ITP significantly improved the total effective rate [RR=1.23, 95%CI (1.17, 1.29), P<0.000 01] compared with that of pure western medicine treatment. Funnel plot showed that publication bias was small. Meanwhile, peripheral platelet count and the number of megakaryocyte which can generate platelet in bone marrow increased, obvious advantage was showed in long-term effect, and adverse reactions were reduced with ITWM treatment in ITP patients. Conclusion The existed limited evidences suggest that ITWM treatment of ITP can significantly improve clinical efficacy. The quantity and quality of research literature were limited, and well-designed randomized double-blind controlled trials with large sample and multi-centers are required for a more reliable conclusion.

Objective: To study the effect of GLP-Ⅱ on residual bowel absorption of glucose in a rat model of short bowel syndrome. Methods: Rats undertaken 75% small bowel resection were randomly assigned to SB group and SB/GLP-Ⅱ group. Another group of weight-matched normal rats(Normal) received normal diet ad libitum was used as control group for SB group. All rats were allowed normal chow on the 1st postoperative day(POD). On the POD6,the intestinal glucose absorption data per unit length as well as per unit weight of ileum were measured by in vivo circulatory perfusion experiment. Results: Length of perfused ileum in 3 groups of rats were not significantly different. Wet weight to length ratio of perfused ileum in SB group was significantly higher than that of normal group,but significantly lower than that of SB/GLP-Ⅱ group. 45min glucose absorption of per cm ileum in SB/GLP-Ⅱ group was significantly higher than that of SB group(P0.05). Conclusions: In a rat model of SBS, GLP-Ⅱ can enhance the intestinal glucose absorption measured as per unit length of resudial ileum and GLP-Ⅱ manifests a trend to increase the glucose absorption measured as per unit wet weight of resudial ileum.

Objective To detect the protein expression of Cripto-1 and CD34 in basal-like breast carcinoma and study the functions of Cripto-1 in basal-like breast cancer angiogenesis,invasion and metastasis.Methods Immunohistochemistry (IHC) was used to detect the expression of Cripto-1 and CD34 in 60 cases of basal-like breast cancer,40 cases of non basal-like breast cancer and 20 cases of normal breast tissues.The clinical relationship between Cripto-1 and basal-like breast cancer were analyzed as well as its connection with CD34 markers MVD.Results The expression of Cripto-1 protein in basal-like breast cancer (42/60,70.00 ％) was significantly higher than that of nonbasal-like breast cancer (19/40,47.50 ％) and normal breast tissue (4/20,20.00 ％) (both P ＜ 0.05).The expression of Cripto-1 protein was positively correlated with the tumor size,clinical stage,lymph nodes metastasis and MVD value in patients of basal-like breast cancer (all P ＜ 0.05),but there was no corelation with the age of the patients (P ＞ 0.05).Conclusions The up-regulation of Cripto-1 expression may be associated with angiogenesis and development in basal-like breast cancer.The effect of Cripto-1 promoting angiogenesis may be an important factor in the acceleration of the local invasion and distant metastasis in basal-like breast cancer.

Objective To evaluate the feasibility of repair of full-thickness skin defects in nude mice with tissue-engineered skin which was constructed by culture of human amniotic epithelial cells (hAECs) and fibroblasts on human de-epidermized dermis (DED).Methods Healthy human amniotic tissues were treated with trypsin at a low concentration in multi-steps to prepare hAECs,and a two-step collagenase digestion was used to treat healthy children's prepuce tissues to prepare fibroblast suspensions.When fibroblasts were cultured in vitro up to passage 3-5 and hAECs up to passage 2,they were seeded on the reticular dermal surface and basement membrane surface of the DED respectively to construct the tissueengineered skin.A total of 20 heahhy male nude mice aged 3-4 weeks were enrolled into this experiment,and full-thickness skin defects were made on the middle of the back of mice.Then,these mice were randomly divided into 2 groups by using a lottery method,and reconstructed full-thickness tissueengineered skin grafts and vaseline oil gauze were used to cover the wounds in the tissue-engineered skin group and control group respectively.The whole body and transplantation sites of the nude mice were observed on day 7,14,21 and 28 after transplantation,the wound healing time and rate were compared between the above two groups,and skin tissues at the transplantation site were harvested at 4 weeks after transplantation and subjected to histological examination.Results HAECs had stem-cell characteristics and expressed octamer-binding protein-4 (OCT-4) and embryonic marker stage-specific embryonic antigen4 (SSEA-4).After 2-week organ culture,the in vitro reconstructed tissue-engineered skin showed 4-9 continuous layers of stratified epithelium,and the histological structure of the epidermis was similar to that of the normal human skin.Compared with the control group,the tissue-engineered skin group showed significantly higher wound healing rates on day 7,14 and 21 after transplantation (57.49％ ± 6.11％ vs.22.93％ ± 4.26％,92.80％ ± 3.10％ vs.54.57％ ± 7.94％,98.83％ ± 0.25％ vs.91.16％ ± 4.79％,respectively;n =10,t =27.36,32.23,11.80,respectively,all P ＜ 0.001),shorter wound healing time [(21.51 ± 1.51) d vs.(28.80 ± 1.14) d,n =10,t =42.23,P ＜ 0.001],with the color of skin grafts closer to that of autologous skin on day 28 after transplantation.Histological examination revealed distinct stratification of the epithelium,obvious keratinization and favorable growth of cells in the dermis in the tissue-engineered skin group,but thin epithelium with some defects,indistinct stratification of the dermis,and inflammatory cell infiltration in the control group.Condusion Tissue-engineered skin constructed by the culture of hAECs and fibroblasts on human DED can survive in nude mice after transplantation,resulting in a more favorable healing of wounds,and is expected to serve as a kind of ideal tissue-engineered skin.
