Objective: To observe the clinical effects of simple obesity treated with abdomen acupuncture. Methods: Sixty patients with simple obesity were allocated to abdomen acupuncture group and body acupuncture group based on the randomized and controlled principle, 30 patients in each group. Fifteen treatments made up one course. The cases were treated for 2 courses. The clinical effects were evaluated by body mass index (BMI) and the declining of body height. Result: The change of BMI and clinical effects were of no significant difference between two groups after 1 course, but there were significant differences after two courses. Conclusion: The clinical effect of abdomen acupuncture treating simple obesity is better, and the effect is persistent and stable.

OBJECTIVE To understand the condition of occupational exposure in hospital,and analyze the tendency during last four years.METHODS Occupational exposure in medical personnel were investivated through questionnaireand reviwed the survey report of quantitative detection of the five serological markers of hepatitis B,in the workers exposed in HBV.RESULTS The rate of occupational exposure had declined year by year during 2005-2008,but the result was opposite for HBV.CONCLUSIONS It′s very effective to decrease occupational exposure by strenghening standardization and putting professional protective knowledge in routine work.After setting up and developing protective system against occupational exposure,it′s more prompt in updating information,protective treatment and follow-up test in serum.It shows that this system is helpful to normalize medical personnel action of occupational exposure.In fact,vaccination is an effective way to avoid medical personnel of infecting HBV.

Objective To investigate the effects of resistin on mesangial cells proliferation induced by high glucose and subsequent change of p38MAPK signal pathway. Methods Human macrophrages were cultured and treated with adenovirus encoding for resistin (Ad-resistin) for 48 h and were then co-cultured with human mesangial cells stimulated by high glucose for another 48 h. Mesangial ceils were harvested and their proliferation was measured by 3H-TdR. Activator protein 1 (AP-1) was examined by immunocytochemistry and laminin of excellular matrix was observed with immuofluorescence. Protein levels of p38MAPK and TGF-β1 were measured by Western blot. Smad2 phosphatase activity was aslo detected by Western blot. Results The mRNA and protein levels of resistin were significantly higher in Ad-resistin treated macrophages than those in Ad treated cells (P<0.01). Over-expression of resistin up-regulated p38MAPK protein levels of human mesangial cells(P<0.05). Resistin also promoted the proliferation of mesangial cells (P<0.01) and the synthesis of laminin stimulated by high glucose. The expression of TGF-β1 and phosphorylation of Smad2 were up-regulated in the mesangial cells (P< 0.05). Conclusion Macrophage cytokine resistin may promote mesangial cells proliferation and abnormal accumulation of excellular matrix stimulated by high glucose via activating p38MAPK signal passway.

ObjectiveTo investigate the effects of ginsenoside Rg1 on apoptosis in spinal dorsal horn in development of morphine tolerance in rats with arthritis.MethodsTwenty-four healthy male SD rats weighing 280-320 g in which intrathecal(IT) catheters were succcessfully implanted without complication were randomized into 4 groups ( n =6 each):group normal saline ( group C) ; group morphine ( group M ) ; group ginsenoside Rg1 (group G) and group morphine + ginsenoside Rg1 (group MG).Arthritis was induced with complete Freund adjuivant injected into the ankle joint of right hind limb according to the method described by Butler et al in all 24 animals.Chronic morphine tolerance was induced by IT morphine 10 μg twice a day for 7 consecutive days in groups M and MG.Ginsenoside Rg1 100 μg was given IT once a day for 7 consecutive days in groups G and MG.Paw withdrawal threshold to mechanical stimulation with yon Frey filaments (MWT) was measured before induction of arthritis (T1,baseline),and IT drug administration (T2) and at day 1,3,5,7 (T3-6) after IT administration.The rats were sacrificed after last MWT measurement and their lumbar segments of the spinal cord ( L3-5 ) were removed for detection of apoptosis in the spinal dorsal horn by TUNEL.ResultsMWT was significantly decreased after induction of arthritis at T2-6 compared with the baseline value before arthritis at T1 in all 4 groups.In group M IT morphine significantly increased MWT at T3.4 compared with the baseline at T2 but the MWT was decreasing at T5.6 indicative of development of morphine tolerance.In group MG,addition of ginsenoside Rgl to IT morphine significantly attenuate the decrease in MWT at T5.6.The number of apoptotic cells in spinal dorsal horn was significantly higher in groups M and MG than in group C,but was significantly lower in group MG than in group M.Concluson Ginsenoside Rg1 can prevent the development of morphine tolerance in rats with arthritis by inhibiting apoptosis in spinal dorsal horn.

AIM　To prepare naftopidil bioadhesive sustained-release capsule and study their pharmacokinetics and relative bioavailability in the dog. METHODS　Bioadhesive polymers such as hydroxypropyl methylcellulse (HPMC) and Carbopol 934 (CP 934) were used in capsule prescriptions. Naftopidil capsule and two formulations of bioadhesive sustained-release capsules (I and II) were given to five healthy male dogs in a cross-over test. The naftopidil concentrations in plasma were determined by a newly developed HPLC method and the pharmacokinetic parameters as well as the relative bioavailability were measured. RESULTS　The C0→∞, Cmax and Tmax of naftopidil capsule was (3728±573) h*ng*mL-1, (697±94) ng*mL-1 and (1.2±0.5) h. These parameters of bioadhesive sustained-release capsule I and II, respectively, were (5518±391) h*ng*mL-1 and (5636±427) h*ng*mL-1; (468±61) ng*mL-1 and (512±72) ng*mL-1; both (4.0±0.7) h. Results from statistics showed that there were significant difference between bioadhesive formulations and the non-bioadhesive one in C0→∞, Cmax and Tmax. The bioadhesive formulations and the non-bioadhesive one were not bioequivalent, the relative bioavailability of the two bioadhesive sustained-release capsules were respectively 150%±14% and 154%±23% when compared with the non-bioadhesive capsule. CONCLUSION　It is much improving bioavailability of naftopidil by using bioadhesion.

BACKGROUND: It remains unclear whether proinflammatory factor, such as tumor necrosis factor-α (TNF-α), γ-interferon and anti-inflammatory cytokine, such as interleukin-10 (IL-10), interleukin-4 (IL-4) levels can change after laryngeal transplantation. OBJECTIVE: To explore the expression of TNF-α and IL-10 in different expressive tissue layers and its relationship during the acute rejection episodes, and to evaluate the role of TNF-α and IL-10 levels in serum for prediction of early acute rejection after laryngeal transplantation. METHODS: Laryngeal heterotopic transplantations were performed in Wistar and Sprague-Dawley rats. According to different dosages of immunodepressant, all recipients were divided into three groups: Group 0 mg, Group 5 mg, and Group 10 mg. Untreated Sprague-Dawley rats served as normal control group. RESULTS AND CONCLUSION: Changes in serum TNF-α and IL-10 levels at postoperation days 3, 7 and 11 were positively correlated with these expressions in the epithelium mucosa and submucosa at various time points after transplantation. These indicate that the high-antigenicity of graft mainly concentrates on the layers of mucosa and submucosa. TNF-α and IL-10 concentrations can serve as indexes for predicting acute rejection after laryngeal transplantation.

Objective To evaluate the significance of weight-bearing lateral radiographs in evaluation of malunited frac-tures of the ankle. Methods 17 patients with malunited fractures of the ankle were treated by different reconstructive operations be-tween March 2010 and October 2012, including 9 females and 8 males, aged from 17 to 64 years. According to the Takakura classifi-cation of ankle arthritis, there were 7 patients in grade 1, 4 in grade 2 and 6 in grade 3. Simple open reduction and internal fixation were performed in 5 patients, supramalleolar tibial osteotomy in 5, lengthening osteotomy of the fibula in 2, supramalleolar tibial and fibular osteotomy in 5. Tibiofibular clear space on the anteroposterior radiograph. Medial clear space, tibiofibular clear space and tib-iofibular overlap on ankle mortise radiographs were compared preoperatively and at last follow-up. Tibial lateral surface angle (TLS), the offset of the center of talar rotation from the tibial axis, and the displacement of tibiotalar articular surface center on weight-bear-ing lateral X-ray were also compared preoperatively and at last follow-up. AOFAS score was used to evaluate the function of the ankle. Results The duration of follow-up was 9 to 32 months. Bone healing was observed in all patients, and the average healing time was 11 to 14 weeks. Ankle joint degeneration grade had no exacerbation. The medial clear space, tibiofibular clear space and tibiofibular overlap had no significant difference between the pre and postoperative. Statistically significant change was seen postoperatively in the values of TLS (76.9°±4.1° vs 80.9°±5.2°). The offset of the center of rotation from the tibial axis and the displacement of tibiotalar articular surface center were changed from 10.8 ± 2.1 mm to 2.0 ± 0.5 mm and 4.5 ± 1.5 mm to 2.2 ± 1.0 mm, respectively. The average AOFAS score was improved from 45.7 ± 15.9 points preoperatively to 82.0 ± 9.9 points postoperatively. Conclusion Weight-bearing lateral radiographs can be used to judge the ankle restoration. Even if the mortise radiograph had relative good realignment, it may ap-pear obvious deformity on lateral radiographs. Good reduction of lateral radiographs requires that the mid axis of the tibia should pass through the center of talar rotation and tibiotalar articular surface be parallel on the lateral radiograph.
