Objective To research the clinical curative effect of pegylated interferon α-2a (Peg-IFNα-2a) combined with ribavirin in treating chronic hepatitis C with positive autoantibodies.Methods The autoantibodies were screened in 93 cases of chronic hepatitis C patients and then the patients were divided into positive group and negative group.Both of the two groups were given therapy with Peg-IFN α-2a combined with ribavirin.The capacity of hepatitis C virus (HCV) RNA,virological response rate,and blood concentration of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were quantified before and in the process of treatment.Results Twenty-eight patients had autoantibodies,with 17 patients of antimitochondrial antibody,8 patients of anti smooth muscle antibody and 3 patients of anti-liver-kidney microsomal antibody-1.The quantity of HCV RNA and the virological response rate had no significant difference before and after treatment (P ＞ 0.05).The concentration of ALT and AST in positive group were higher than those in negative group before and in the process of treatment,while there were obvious differences only after 36 weeks of treatment (P ＜ 0.05).Conclusion Peg-IFN α-2a combined with ribavirin is effective for chronic hepatitis C for all the patients,but liver function of autoantibody negative patients have a better recovery.

High - risk corneal transplantation immunological rejection is a primary factor affecting the success or failure of the corneal transplantation. As a result, application of immunosuppressive agent in high - risk corneal transplantation rejection reaction occupies an irreplaceable position. However, many local and systemic adverse reactions appeared in the process of application. In order to improve the achievement ratio of the corneal transplantation, experts and scholars at home and abroad have obtained remarkable achievements in dosage form, route of administration and drug combination;meanwhile, a considerable progress was also made in genetic engineering. This paper is a review of prevention and treatment on high - risk corneal graft rejection reaction.

Objective To investigate the feasibility of autogenous vein graft as a connector to repair recurrent laryngeal nerve(RLN) defect. Methods 20 healthy dogs were randomly devided into 4 groups: group 1(n=6), 2(n=6), 3(n=5) and control group(n=3). Left RLN of dogs in group 1,2,3 were resected for 1,2,3 centimetres respectively and followed by repairment with autogenous vein graft, while RLNS of dogs in control group were resected but not conducted by autogenous vein graft. Six months after operation, the vocal fold movement, phonation and induced action potensial as well as morphologic observation of the aryngeal muslces were studied. Results In group 1, phonation of dogs was all restored to normal. The vocal fold of RLN resected side showed no atrophy symmetrical to the normal side and adducted apparently when phonating. Furthermore thyroarythenoid muscle and posterior cricoarytenoid muscle both could generate induced action potentially. Regenerated nerves in verin graft and distal nerve were observed by light microscope and electron microscope. In group 2,3 and control group hoarseness improved six months after op eration, the vocal fold of RLN resected side was atrophied apparently and fixed paramedianly. Fissure existed in glottis when vocal fold closed, and compensative movement of opposite vocal fold across over the median line was found. Thyoarthenoid muscle and posterior cricoarytenoid muscle unable to generate an action was found. Regenerated nerves were not observed in vein graft or distal nerve by light microscope and electron microscope. Conclusions It is feasible to repair RLN defect in certain length by autogenous vein graft.

Objective To evaluate the prognostic value of white blood cell and hemoglobin in patients with acute aortic dissection(AAD).Methods White blood cell.hemoglobin and fibrinogen were measured in 42 AAD patients.The mortality during hospitalization was observed and the short-term prognosis in AAD patients was as-seased.Results There was 13 death during hospitalization.with the mortality of 30.95%.The value of white blood cell was higher in death group than in survival group[(13.73±6.91)×109>/L vs.(9.43±4.97)×109>/L.P< 0.05).The value of hemoglobin was lower in death group of than in survival group[(118.54±22.38)g/L vs. (131.72±18.17) g/L,P<0.05].There were no differences in the value of fibrinogen between the groups [(3.15±1.15)g/L vs.(3.48±1.24)g/L,P>0.05).The mortality in the group of elevated white blood cell(≥10.0×109>/L)was higher than that in the group of normal white blood cell(10.0×109/L)(41.18%vs.24%.P<0.05).The mortality in the group of decreased hemoglobin(≤110g/L)was higher than that in the group of nor-mal hemoglobin(>110 g/L)(50.00%vs.27.78%,P<0.05).Conclusion The value of white blood cell and he-moglobin could help to assess the short-term prognosis of patients with AAD.

The psychiatric problem has become a global public health issue. The model of mental health service advocate that“Treatment of disease occurred in the hospital, but rehabilitation and management in the community”. This brings great challenge to the community health service center. By comparing the domestic and foreign mental health service system, this paper discusses the necessity of carrying out the standardized training of general practitioners in psychiatry and psychology.

Chronic alcohol consumption is a leading cause of chronic liver diseases worldwide, resulting in cirrhosis and hepa-tocellular carcinoma. Almost all heavy drinkers develop fatty liv-er, but only 20% ~40% of them develop more severe forms of alcoholic liver diseases such as alcoholic hepatitis and alcoholic fibrosis, and the underlying mechanisms that contribute to the disease progression remain largely unknown. The animal models which can mimic human alcoholic liver diseases are very neces-sary tools for better understanding and exploring the therapy strat-egy of the disease. Currently, the most widely used models for alcoholic liver injury are Lieber-DeCarli model, Tsukamoto-French model, Gao-binge model and others. Here we summarize the recent advances in animal models recapitulating different fea-tures and etiologies of human alcoholic liver diseases. These ani-mal models will be very useful for the mechanism study of alco-holic liver diseases and further new therapeutic drug screening.

Objective To investigate epidemiological characteristics of Salmonella infection in children with infectious diarrhea in Zhuhai City from 2009 to 2014 .Methods Isolation ,culturing ,biochemical identification and serotyping of Salmonella were carried out in strains isolated from stool specimens of 4 395 children with infectious diarrhea in inpatient and outpatient settings in Zhuhai Municipal Maternal and Child Healthcare Hospital from 2009 to 2014 ,and data were statistically analysed .Results A total of 546 strains of Salmonella was isolated(the overall isolation rate was 12 .42% ) and 30 serotypes were identified .Among children with Salmonella infection ,those under 3 years old accounted for 93 .22% .There was no statistically significant difference of isolation rate between male and female children with infectious diarrhea(P<0 .05) .June and July were peak period of Salmonella infection ,and the isolation rate was 16 .40% and 16 .09% respectively .Isolates of Salmonella typhimurium ,Salmonella enteritidis and Salmonella stanley account for 50 .92% ,13 .55% and 10 .26% respectively ,which were dominant serotypes .Conclusion Salmonella is the main pathogenic bacteria in children with infectious diarrhea in Zhuhai area ,and Salmonella typhimurium is the main serotype .The infec‐tion of Salmonella might be correlated with children′s age and climate change .

Pegylated interferon plus ribavirin is still the standard treatment for hepatitis C,but the efficacy is often restricted by adverse events.HCV genotypes,viral dynamics during early treatment and gene polymorphism may be useful in predicting the efficacy of antiviral treatment.Several strategies have emerged to improve outcomes including low accelerating dose regimen (LADR) and prevention of complications.Direct antiviral drugs have been already used for HCV genotype 1 patients,and demonstrated improved efficacy.Besides,inhibitors and vitamin D may also be applied in antiviral therapy to improve the efficacy.This article reviews efficacy predictors,standard therapy,strategies and research on new medicaments in antiviral treatment of hepatitis C.
