Objective To observe the therapeutic effect of oral use of Yibai Tongfeng Pills for the treatment ofgouty arthritis with damp-heat obstruction. Methods One hundred and sixteen gouty arthritis patients were randomized into treatment group (N = 62) and control group (N = 54). The treatment group was treated with Yibai Tongfeng Pills orally, and the control group was treated with oral use of Colchicine Tablets and Sodium Bicarbonate Tablets at acute stage and with oral use of Benzbromarone Tablets at remission stage. Twelve weeks constituted one treatment course. Clinical efficacy of the two groups was evaluated after treatment, and the changes of C-reactive protein(CRP), white blood cell(WBC) and uric acid(UA) levels in the blood of the two groups were observed before and after treatment. Results (1) The total effective rate of the treatment group was 93.55%and that of the control group was 83.33%, the difference being significant(P<0.05).(2) After treatment, the scores of syndrome manifestations of the two groups were obviously decreased(P < 0.05 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group(P<0.05) . (3) After treatment, CRP, WBC and UA levels in the blood of the two groups were much improved(P < 0.05 compared with those before treatment), and the improvement of CRP in the treatment group was superior to that in the control group(P<0.05), while the differences of the improvement of WBC and UA between the two groups were insignificant (P > 0.05). Conclusion Yibai Tongfeng Pills are effective for the treatment of gouty arthritis with damp-heat obstruction by improving syndrome manifestations and rapidly decreasing CRP level.

Objective To explore family functioning and related factors in anxiety disorder(AD)adoles cents.Methods 84 adolescent patients with AD and 124 controls without mental disorder matched by gender,age,and residential township were assessed with Family Adaptability and Cohesion Scale(FACES-Ⅱ),Family Assessment Device.Chinese version(FAD-CV)and demographic questionnaires.Results There were statistical differences between case and control groups in family economic conditions(P<0.05).There was lower family cohesion in AD group(64.82±9.63)than that in the control group(69.72±8.91);the scores of communication,emotional involvement and behavioral control were higher in AD group((2.34±0.45),(2.52±0.44),(2.46±0.32))than that in controls((2.12±0.34),(2.36±0.42),(2.24±0.24)),all P<0.05.Logistic regression analysis showed that better family economic condition(OR=0.784;95%CI:1.459-3.396)and higher cohesion of family(OR=0.969;95%CI:0.942～0.998)were protective factors for AD,while over-strict behavioral control (OR=2.181;95%CI:0.993～2.441)was a risk factor for AD.Conclusion There are different family functioning characters between AD and controls,and the intimacy relationship and suitable behavior control in family may improve the mental health of adolescents.

Objective To investigate expression characteristics in regenerating hair follicles induced by Wnt10b, and to explore mechanisms underlying Wnt10b-induced regeneration of hair follicles. Methods Both adenovirus containing the Wnt10b gene(AdWnt10b)and that containing the green fluorescent protein-encoding gene(AdGFP)were amplified in HEK-293 cells and purified by caesium chloride density gradient centrifugation. A total of 36 C57BL/6J mice were randomly and equally divided into the AdWnt10b group and AdGFP group to be intracutaneously injected with AdWnt10b and AdGFP on the back respectively. Three mice were sacrificed on day 2.5, 5, 7, 9, 14 and 28 after the injection separately, and skin samples were resected from the injected sites subsequently. Hematoxylin and eosin(HE) staining and immunohistochemical staining were performed to observe hair follicle structure, analyze expression characteristics of the Wnt signaling pathway, and to estimate proliferative activity of regenerating hair follicles induced by Wnt10b. Results As HE staining showed, new hair follicles appeared as early as day 5 after the injection, then grew normally, and entered into catagen phase on day 28 in the AdWnt10b group. Immunohistochemical staining showed that AE15 expression was observed in new hair follicles as early as day 5 after the injection in the AdWnt10b group, then increased along with the growth of hair follicles, but decreased on day 28. On day 5 after AdWnt10b injection, both β-catenin and Lef1 expressions were seen in the cell nucleus. Lef1 was expressed specifically in hair germs and hair matrix, and its expression began to decrease on day 28. In addition, Ki67 expression was observed in the epidermis and outer root sheath of hair follicles as early as day 2.5 after the injection, in the bulge region of hair follicles on day 2.5, 7, 9 and 14, and in hair matrix cells as early as day 7. Conclusion Wnt10b could induce regeneration of hair follicles with normal structure, likely by activating the canonical Wnt signaling pathway in hair follicle stem cells and their daughter cells.
