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.

Recent studies have revealed that tumor suppressor PTEN does not only closely relate to the development and differentiation of brain but also get extensively involved into the pathophysiological processes of ischemic brain injury.Through research on the mechanisms of molecular regulation mediated by PTEN in ischemic brain injury will provide new perspectives for the treatment of ischemic brain injury.

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.

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.

Objective: To assess the values of conventional vascular ultrasound (US) and superb micro vascular imaging (SMI) for diagnosing carotid artery stenosis in relevant patients. Methods: A total of 37 patients of extra cranial carotid stenosis (with 70 blood vessels) treated in our hospital from 2014-08 to 2015-03 were retrospectively studied. Digital subtraction angiography (DAS) examination was used as golden standard, the diagnostic efifcacies for carotid artery stenosis by US and by SMI were compared. Results: The accuracy, sensitivity and specificity for diagnosing carotid stenosis by US were 81.42%, 83.33% and 80.95%; by SMI were 91.43%, 92.16% and 89.47% respectively. Conclusion: US and SMI showed good agreement for diagnosing carotid artery stenosis, while SMI was superior to US for accurately assess the degree of carotid stenosis, it might be used as a more reliable method for evaluating carotid plaque and stenosis in relevant patients.

Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.
