[Objective]To assess the success of hallux valgus surgery of oblique and impaction osteotomy of first metatarsal neck.[Method]The outcome of 36 patients(45 feet)treated by this technique for symptomatic hallux valgus deformity was reviewed.The follow-up was two years.Lateral and AP radiographs were taken in a standing position pre-and postoperativly and hallux valgus angle(HV angle)and intermetatarsal angle(IM 1~2 angle)were measured accordingly.The efficacy of the surgery was evaluated by JOA scoring for foot disorders.[Result]The fracture healing was excellent.There was no case of delay union and nonunion.Two cases(three feet)were found to have superficial infection.The mean HV angle and IM 1~2 angle was revised by 15.6? and 4.2? respectively.JOA score was elevated for 29.6 points.[Conclusion]Hallux valgus can be corrected in three-dimension by the technique of first metatarsal neck osteotomy and inverted impaction fixation.

ObjectiveTo investigate the effect of therapeutic hypercapnia on hepatic ischemia-reperfusion (I/R) injury in rat liver transplantation.MethodsMale specific pathogen-free adult Wistar rats aged 6 weeks weighing 220-280 g were used in this study.Sixteen rats in which liver transplantation was successfully performed were randomly divided into 2 groups ( n =8 each): liver transplantation group (group LT) and therapeutic hypercapnia group (group TH).In group TH,PaCO2 was maintained at 80-100 mm Hg by inhalation of CO2 for 1 h at the begining of reperfusion.MAP,PaO2 and PaCO2 was recorded during reperfusion.Blood samples were obtained at 2 h of reperfusion for determination of serum ALT,AST,TNF-α,IL-1 and IL-6 levels,and then the rats were sacrificed and transplanted liver was immediately removed for determination of NF-κB activity and apoptosis and microscopic examination.The apoptotic index was calculated.ResultsMAP,PaO2 and PaCO2 were higher,and serum ALT,AST,TNF-α,IL-1 and IL-6 levels,NF-κB activity and apoptotic index lower in group TH than in group LT ( P ＜ 0.05).The histopathologic damage was ameliorated in group TH as compared with group LT.Conclusion Therapeutic hypercapnia can attenuate hepatic I/R injury in rat liver transplantation by inhibiting inflammatory response and apoptosis.

OBJECTIVETo determine the risk factor of HCC in Guizhou.

METHODSA group case-control study design was conducted between 762 cases and 798 controls in Guizhou province. The main related-factors were analyzed with unconditional logistic regression model and evaluated by odds ratio (OR) and 95% confidence interval (95% CI).

RESULTSThere are significant differences between cases and controls in regarding to cigarette smoking 210 (27.6%),non-alcoholic fatty liver disease 336 (44.1%), alcoholic liver disease 245 (32.2%), family history of HCC 141 (16.5%), alcohol consumption 300 (39.4%), HBV infection 436 (57.2%), pickled food 290 (38.1%), and economic status 5 years ago 420 (55.1%) in cases,and cigarette smoking 116 (14.5%),non-alcoholic fatty liver disease 160 (20.1%), alcoholic liver disease 101 (12.7%), family history of HCC 40 (5.0%), alcohol consumption 180 (22.6%), HBV infection 82 (10.3%), pickled food 225 (28.2%), and economic status 5 years ago 647 (81.1%) in controls, with OR of each variable was 3.520, 2.464, 4.330, 2.219, 2.451, 19.245, 6.212, 0.174 respectively, P less than 0.01.

CONCLUSIONHBV infection and pickled food were the most common risks for HCC in Guizhou. Alcohol consumption excessively and cigarette smoking may increase the risk too.

PURPOSE: The house dust mite (HDM) is one of the most important sources of indoor allergens and a significant cause of allergic rhinitis and allergic asthma. Our previous studies demonstrated that Vibrio vulnificus flagellin B (FlaB) plus allergen as a co-treatment mixture improved lung function and inhibited eosinophilic airway inflammation through the Toll-like receptor 5 signaling pathway in an ovalbumin (OVA)- or HDM-induced mouse asthma model. In the present study, we fused the major mite allergen Derp2 to FlaB and compared the therapeutic effects of the Derp2-FlaB fusion protein with those of a mixture of Derp2 and FlaB in a Derp2-induced mouse asthma model. METHODS: BALB/c mice sensitized with Derp2 + HDM were treated with Derp2, a Derp2 plus FlaB (Derp2 + FlaB) mixture, or the Derp2-FlaB fusion protein 3 times at 1-week intervals. Seven days after the final treatment, the mice were challenged intranasally with Derp2, and airway responses and Derp2-specific immune responses were evaluated. RESULTS: The Derp2-FlaB fusion protein was significantly more efficacious in reducing airway hyperresponsiveness, lung eosinophil infiltration, and Derp2-specific IgE than the Derp2 + FlaB mixture. CONCLUSIONS: The Derp2-FlaB fusion protein showed a strong anti-asthma immunomodulatory capacity, leading to the prevention of airway inflammatory responses in a murine disease model through the inhibition of Th2 responses. These findings suggest that the Derp2-FlaB fusion protein would be a promising vaccine candidate for HDM-mediated allergic asthma therapy.

Objective: To establish a monitoring model of stellate ganglion discharge in rats. Methods: Thirty healthy Sprague-Dawley rats of either sex, aged 6-7 weeks, weighing 230-270 g, were selected.The left stellate ganglion was isolated after anesthesia and hung on the platinum electrode head to observe its electrical signal.Heart rate was recorded immediately after successful anesthesia (T₀), immediately after the stellate ganglion was suspended in the electrode head (T₁), at 10, 20 and 30 min after the stellate ganglion was suspended in the electrode head (T_2-4), the frequency and amplitude of discharge of the stellate ganglion was recorded at T_1-4.After recording the nerve electrical signal at T₄, the stellate ganglion was locally infiltrated with 0.2% lidocaine 0.2 ml and then the frequency and amplitude of discharge was recorded 5 min later (T₅). The occurrence of Horner′s syndrome was considered as a sign of successful block, and the success of block was recorded. Results: There was no significant difference in heart rate at each time point (P>0.05). Paroxysmal clustered and rhythmically regular neuroelectrical activity of stellate ganglion was found at T_1-4, and there was no significant difference in the frequency and amplitude of discharge at each time point (P>0.05). The frequency and amplitude of discharge of stellate ganglion were significantly decreased at T₅ than at T_1-4 (P<0.01). Conclusion The discharge monitoring model of stellate ganglion is successfully established in rats.
