OBJECTIVETo explore clinical effects of digital artery bilobed flap for the treatment of skin degloving injury of thumb.

METHODSFrom January 2007 to December 2012, 45 patients with skin degloving injury of thumb were treated with grafting of digital artery bilobed flap. There were 39 males and 6 females, ranging in age from 19 to 46 years, with an average of 32 years. The disease course ranged from 0.5 to 15 h. Eighteen patients suffered from defect of palmar skin above nail root and nail bed, 19 patients suffered from skin degloving injury of thumb phalangette, and 8 patients had whole skin degloving injury of thumb. The double lobe flaps were designed at the ulnar side of middle finger and the radial side of ring finger according to the defect of thumb skin. The arteria digitalis communis between the middle and ring fingers and its two branches of arteriae digitales propriae supplying the two fingers were used as a vessel pedicle. The flap with digitales proprii nervi was transposed and used to cover the exposed phalanx of thumb. Full thickness graft was used for the donor site. Observation of the appearance, texture, color and wear resistance of flap, appearance, color and depression of grafting area, skin feeling, and finger activities was conducted.

RESULTSAll the flaps and grafts were alive. Forty-three patients were followed up with an average duration of 25 months, and two patients lost follow-up. The color and texture of the flaps were similar to that of the contralateral thumb pulp. The average two point discrimination was 4.2 +/- 0.3 mm. The color of graft skin was slightly deeper than that of the surroundings skin.

CONCLUSIONDigital artery bilobed flap graft is an effective and ideal operation, which is of low risk and high success rates for skin degloving injury of thumb.

Objective To discuss effects of Wugong Baidu Drink on expressions of Bcl-2, NF-κB mRNA genes related to the apoptosis of HaCaT in psoriasis. Methods Wistar rats were randomly divided into 6 groups:blank group, Western medicine control group, TCM control group, and Wugong Baidu Drink high, medium, and low dose groups. They were given normal saline, methotrexate suspension, compound natural indigo capsule suspension, and the different doses of Wugong Baidu Drink for gavage, respectively. Drug-containing serum of each group was prepared, and was put in the HaCaT respectively to subculture. The intervention effect of different Drug-containing serums on expressions of objective genes were detected through PR-PCR method. Results Drug-containing serum of each group could decrease the expressions of Bcl-2 mRNA and NF-κB mRNA. The most obvious effects were shown in the groups of Western medicine control group and Wugong Baidu Drink high dose group. All Wugong Baidu Drink groups showed a dose-response relationship. Conclusion Wugong Baidu Drink probably can promote the apoptosis of HaCaT by reducing the gene expressions of Bcl-2 and NF-κB. It can also decrease immune response by regulating serum factors related to T cells to play the role of anti-psoriasis.

According to the existing Provisions for Drug Registration (SFDA Order No. 28), applications for new drugs of traditional Chinese medicine are divided into two parts: the applications for drug clinical trial and for drug production (including new drug certificate). It will last for about 10 years from the application for drug clinical trial to get approving, and it also remains many problems and the low probability to succeed. From the sight of pharmaceutical review, there are mainly two aspects of regulatory compliance and technical issues, mainly for changes without approval of the competent authorities of the country. For example, sample preparation and approval of clinical trial process are significant changes. Technical problems are reporting incomplete data or information submitted does not comply with the technical requirements for review, such as: production process validation does not provide information, the preparation of samples for clinical trials and field inspection, production information, or the information provided does not meet the technical requirements. This paper summarizes the frequently asked questions and to make recommendations to advise applicants concerned, timely detection of problems, avoid risk, improving the quality and efficiency of the application for registration.

Objective:To analyze the job preference of doctors at township health center ( THC) and provide references for formulating effective policy. Methods:238 cases of doctors were sampled from Shandong, Anhui and Shaanxi provinces. Using a discrete choice experiment, we analyzed the data with a conditional logit model. Results:The most important job attribution was salary, followed by education for children, permanent post, work location, training opportunity, and years before promotion. The OR value of the monthly income of 8 000 yuan is 7. 0 compared to 2 000 yuan. Doctors will pay 3 857 yuan and 3 294 yuan respectively for better education for children and perma-nent posts. Monthly income increasing to 8 000 yuan will reduce the quitting rate from 35% to 8%, and providing better education for children and permanent posts will reduce 5%. The permanent posts at township health center and non-permanent posts in county hospital have the same appeal to the doctor. Conclusion:When choosing a job, doc-tors at THCs valued salary the most. Improving the education level for children can be beneficial for attracting and re-taining doctors at THCs. A permanent post is more attractive to doctors than non-permanent posts at THCs.

Objective To investigate the serum levels of Th1 and Th2 cytokines and explore its roles in development and clinical features in the elderly patients with eczema. Methods The serum levels of interleukin-2(IL-2),interleukin 4(IL-4),interleukin-10(IL-10),interleukin-12(IL-12) and tumor necrosis factor alpha (TNF-α) were derected in 50 elderly patients with eczema and 34 healthy elderly as control by enzyme-linked immunosorbent assay (ELISA). The above cytokines were compared between acute and chronic,generalized and localized eczema. Results The serum levels of IL-2 [(16.03±0.47)vs.(15.72±0.33) μg/L],IL-4[(14.04±0.56) vs.(13.56±0.16) μg/L],IL-10 [(33.01±5.40) vs.(29.49± 1.07) μg/L],IL-12 [(39.32± 3.54) vs.(37.93± 1.17) μg/L]and TNF-α [(27.33±0.72) vs.(26.38±0.48) μg/L] were higher in elderly eczema than in control (t/t'=3.55,5.74,4.49,2.58,6.69,all P＜0.05).The serum levels of all cytokines tested in acute eczema(t/t'=3.59,4.68,3.35,2.00,6.44,all P＜0.05),the levels of IL2,IL-4,IL-10 and TNF-α t'=2.46,5.50,3.83,3.10,P＜0.05,but not IL-12 (t'=1.77,P＜0.05) inchronic elderly eczema were increased as compared with control ( P ＜0.05).No significant difference was found in cytokines levels between acute and chronic eczema (P＞0.05)as well as between generalized and localized eczema(t=0.18,5.74,4.49,0.91,0.25,1.11,P＞0.05). Conclusions Changes of Th1 and Th2 cytokines may play some role in the pathogenesis of elderly eczema,but not characterized by clinical types of eczema.

Objective To investigate the effect of emergency case video segmentally introduction combining with simulation in cultivation of undergraduate nursing students′skills of trauma management. Methods A group of 55 undergraduate nursing students, recruited in the control group from September 2013 to April 2014, were instructed by traditional teaching method, the trauma management skill was delivered by lecture, video and group based practice.
