BACKGROUND:Daclizumab can be special y combined with the inerleukin-2 receptor on the surface of activated T cells in human body, and this method can reflect the close of interleukin-2 receptor thus inferring the effect of induction therapy. At present, the daclizumab has been widely used in renal transplantation, but there is no consensus on its clinical application in liver transplantation. OBJECTIVE:To investigate the expression of serum CD25+T cells and soluble interleukin-2 receptor in the patients receiving daclizumab for liver transplantation during perioperative period. METHODS:A total of 58 patients received orthotopic liver transplant for the first time were included and then the patients were randomly divided into two groups:control group (n=28) and treatment group (n=30). The patients in the two groups were treated with tacrolimus, mycophenolate mofetil and corticosteroids triple immunosuppressive regimen. The patients in the treatment group received immune induction therapy with daclizumab, and the patients in the control group did not receive daclizumab. RESULTS AND CONCLUSION:Flow cytometry and enzyme-linked immunosorbent assay showed the expression levels of CD25+T cells in the treatment group were significantly lower than those in the control group at different time points after liver transplantation (P<0.01);and the expression levels of soluble interleukin-2 receptor in the treatment group were lower than those in the control group during transplantation and at the first day after transplantation (P<0.05, P<0.01). At 6 months after transplantation, the incidence of acute rejection was decreased in the treatment group (P<0.01). The results indicate that daclizumab can effectively suppress the expression level of CD25+T cells, as wel as the expression level of soluble interleukin-2 receptor in the peripheral blood in the early stage of liver transplantation, thus effectively reducing the rate of acute rejection.

Objective To observe the clinical effect of the quadruple therapy of integrated traditional Chinese and western medicine for treatment of patients with paralytic ileus.Methods A prospective randomized control trial was conducted.Ninty-five patients with paralytic ileus diagnosed by Tianjin First Central Hospital from January 2015 to February 2016 were randomly divided into a control group (47 cases) and a research group (48 cases).Routine western medical treatment was given to the patients in control group;on the basis of western medical routine treatment,quadruple therapy was applied to the patients in the research group,including alprostadil injection 10 μg,intravenous drip,once a day;Xuebijing injection 40 mL,intravenous drip,twice a day;liangge powder with modification (ingredients or their dosages being added and/or subtracted) composed of rhubarb 10 g,mirabilite 10 g,gardenia 15 g,weeping forsythia 20 g,scutellaria 15 g,glycyrrhiza 6 g,mint 6 g,bamboo leaves 10 g,honey 10 g.administered by gastric tube;point selection principle:zusanli (ST36),sanyinjiao (SP6),tianshu (S25),hegu (LI4),yanglingquan (GB34),zhongwan (CV12),xiawan (CV10),dachangshu (C07)etc.No.30 filiform needle was used to be perpendicularly inserted by moderate and equi-librious acupuncture technique,needle retaining being 30 minutes,once a day for 72 hours.The numbers of the patients with abdominal pain,abdominal distension,nausea and vomiting,absence of exhausting and defecation,gurgling sound attenuation or disappearance,abdominal X-ray abnormality,and the first defecation time,gurgling reappearance time,disappearance time of main symptoms were observed.The clinical effects of these two groups were statistically analyzed.Results After treatment in the two groups,the numbers of patients with abdominal pain,abdominal distension,nausea and vomiting,absence of exhausting and defecation,gurgling sound attenuation or disappearance,abdominal X-ray abnormality were all significantly reduced compared with those before treatment,except the nausea and vomiting symptom,the degrees of descent of other indexes were more remarkable in the research group (abdominal pain:7 cases vs.44 cases,abdominal distension:6 cases vs.45 cases,absence of exhausting and defecation:3 cases vs.48 cases,gurgling sound attenuation or disappearance:11 cases vs.43 cases,abdominal X-ray abnormality:12 cases vs.48 cases),the time of first defecation in research group (hours:22.65 ± 6.72 vs.34.35 ± 5.38),gurgling reappearance time (hours:40.36 ± 6.99 vs.51.33 ± 5.80),symptom disappearance time (hours:51.44 ± 9.41 vs.60.10 ± 5.48) in research group were all shorter significantly than those in control group (all P ＜ 0.05).The total effective rate in the research group was obviously higher than that of the control group [93.75％ (45/48) vs.87.37％ (37/47),P ＜ 0.05].Conclusions The therapeutic effects of the quadruple therapy of integrated traditional Chinese and western medicine are remarkable for treatment of paralytic ileus.

OBJECTIVE:To study the effects of common percutaneous enhancers on transdermal permeability of cetirizine hy-drochloride(CET). METHODS:Using pH 7.4 phosphate buffer as receiving solution,accumulative permeation rate as index,mod-ified Franz diffusion cell was used to investigate the effects of common percutaneous enhancers on transdermal permeability of CET in skin of abdomen isolated from mice,such as azone (0.06%-2.5%),oleic acid (0.5%-10%),1,3-propanediol (0.5%-10%),propanetriol(0.5%-5%). RESULTS:1,3- propanediol had no improvement effect on the permeability of CET. 24 h accu-mulative permeation amount of CET in 0.06% azone,0.5% oleic acid and 1% propanetriol were the highest among same types, being 227.94,85.25 and 215.15 μg/cm2,respectively. CONCLUSIONS:Of four percutaneous enhancers,the transdermal enhanc-ing efficiencies from high to low are azone>glycerol>oleic acid>1,3-propanediol. Azone and glycerol have the conspicuous pene-tration enhancing effects.

Objective To assess the leading causes of death and disability adjusted life year (DALY) due to non-communicable disease (NCD) in China.Methods World Health Report 2004 published by the World Health Organization (WHO) was reviewed,including total deaths,deaths per 100 000,agestandardized death rate per 100 000,total DALYs,DALYs per 100 000 and age-standardized DALYs per 100 000 by cause and by member state.Diseases or injuries were assigned to three levels:communicable diseases,NCD and injuries (the first level); categories of disease or injure (the second level); specific diseases (the third level).R2.15 was used for data analysis.Results NCD causes 737.6 million deaths,141million total DALY years,627 age standardized mortality per 100 000,and 10 829 age-standardized DALYs per 100 000.NCD account for 79.4％ and 70.3％ total death or all-cause DALYs.Conclusions Cardiovascular disease,malignant neoplasm and respiratory disease were the leading causes of death,while neuropsychiatric disorder,cardiovascular disease and sense organ disease were the most important causes of DALYs.Among China,the United Kingdom,the United States,Canada,Japan,Korea and India,China ranked second in age-standardized mortality rate of chronic disease.DALYs of esophagus cancer and chronic obstructive pulmonary disease were 6 or 2 times of world average level.Besides,the increasing trend in the prevalence of diabetes mellitus remains impressive.

Objective To compare the efficacy of total pelvic floor reconstruction with mesh patch and vaginal hysterectomy with anterior and posterior vaginal wall repair for presby-pelvic floor dysfunction patients.Methods We randomly chose 92 pelvic floor dysfunction inpatients of our hospital from September 2007 to February 2009 and divided them into 2 groups:total pelvic floor reconstruction group(n=70) underwent total pelvic floor reconstruction with mesh patch[12 patients of this group complicated with stress incontinence,4 patients received tension free vaginal tape-obturator(TVT-O) simultaneously];control group(n=22) received vaginal hysterectomy with anterior and posterior vaginal wall repair(3 patients of this group complicated with stress incontinence).A follow-up for 3 to 18 months after the surgery were taken in all the patients.Results In total pelvic floor reconstruction group,no recidivate case was found and the FOP scores and cure rate were 0 and 100% respectively.In control group,there were 7 recidivate cases,all of who were primary vagina anterior wall bulge patients.The cure rate of control group was 68%;For the patients complicated with stress incontinence,they were all cured by TVT-0 or by ascending the front patch in total pelvic floor reconstruction group,but 1 case was as before operation and 2 cases were even worse in control group.Conclusion Total pelvic floor reconstruction with vicarious materials had a definite efficacy for presby-pelvic floor dysfunction.

Objective To review the clinical features of drug-induced liver injury (DILI) in elderly Chinese patients.Methods A literature search was conducted with the key wordsdrug-induced liver injury ordrug-induced liver disease andelderly; four Chinese medical databases were used:including Chinese Biomedical Literature Database (CBM),Chinese Science and Technology Periodical Database (VIP),Wanfang Database and China National Knowledge Infrastructure (CNKI),from when the bases established to December 2011.Data from retrieved literatures of retrospective controlled studies of DILI were analyzed by SPSS 14.0 software.Results Five studies met the inclusion criteria,including 275 elderly patients (aged group) and 602 non-elderly patients (non-aged group) with DILL There was no significant difference in gender between the two groups (P ＞ 0.05).Clinical manifestations of jaundice,fatigue,anorexia,and skin itching were more commonly seen in the aged group (P ＜ 0.01).Cholestatic hepatic injury occurred more frequently in the aged group than in the non-aged group [24.9％ (61/245) vs.18.8％ (102/245),P ＜ 0.05],while hepatocellular type occurred more frequently in the non-aged group [64.3％ (350/544) vs.55.1％ (135/245),P ＜ 0.05].More DILI were induced by Chinese herb medicine and cardiovascular drugs in the aged group than in the non-aged group [47.0％ (79/168) vs.35.9％ (93/254) and 8.3％ (14/168) vs 1.2％ (3/259) respectively,P ＜ 0.05].As for the prognosis,there was no significant difference in clinical cure and improvement rate between the two groups [84.4％ (141/167) vs.81.5％ (291/357),P ＞0.05].Conclusion The elderly are more sensitive to the drugs and have a high risk of DILI.Prevention and timely diagnosis and treatment of DILI are particularly important for elderly patients.

0.05) between two groups.Conclusion Two surgicel porcedures offer smilar results in the surgical treatment of primary spontaneous pneumothorax.Both techniques are equally safe,small traumatic,pain controllable,and there are little postoprerative complications and the relapse rate is very low.

Objective To summarize and explore the clinical characteristics,treatment and outcome of measles in pediatric liver transplant recipients.Method A total of 56 recipients underwent pediatric liver transplantation from June 2013 to April 2014,and 4 recipients suffered from measles post-liver transplantation with the incidence being 7.1％.The data of 4 recipients were retrospectively analyzed.All of the 4 cases were subjected to liver transplantation at our center for biliary atresia and cholestasis liver cirrhosis.All the patients received the combined immunosuppressive regimen on the basis of tacrolimus.All the patients did not accept the immunization with measles vaccine because of the primary liver diseases.All the cases presented the clinical manifestations of cough,high fever (T ＞38.5℃C) and conjunctiva congestion before the rashes came out.Maculopapular rashes appeared about 4 days after the fever.The rashes first appeared from the skine post aurem,face,neck,and then spread to trunk and extremities.Koplik's spots on the buccal mucosa were observed in all the 4 cases.The serological test of IgM antibodies to measles was done.The treatment was adjusted as soon as the diagnosis of measles was clear.Immunosuppressants were decreased or stopped,intravenous immunoglobulin (IVIG) combined with anti-infection drugs was given.Result The clinical manifestation of measles in pediatric liver transplant recipients was serious.There were 3 cases complicated with pneumonia,and one case with laryngitis.Two cases presented severe measles pneumonia and developed into severe respiratory failure requiring mechanical ventilation.Three eases recovered from the therapy and 1 case died of respiratory failure.Conclusion Pediatric liver transplant recipients who suffered from measles are at high risk of severe pneumonia.Measles pneumonitis is frequently fatal in immunocompromised pediatric patients.The treatment shoule be given as soon as possible.

Objective To study the effects of bone mesenchymal stem cells(BMSCs)transplantation on pulmonary tissue fibrosis in silicosis rats.Methods Forty-two healthy female SD rats were randomly divided into 4 groups:group A,B,C and D.The group A,B and C received intratracheal injection of silica crystals(SiO2)to establish silicosis mouse models,while the group D received the infusion of physiological saline.BMSCs were injected by the tail vein at 6 h after modeling or on 42 d in the group B and C.Six rats in each of group A,B,and D were sacrificed on 14 d,and other 6 rats in each group were sacrificed on 56 day.The morphological changes of the lung tissues were observed by HE staining;the content of hydroxyproline(Hyp)in the lung tissue homogenate was detected by ELISA.Results The lung tissue pathological changes in the group A were dominated by acute inflammatory response on 14 d after model construction,and fibrosis reaction on 56 d;the pathological changes in the group B and C were lighter than those in the group A;while no obvious abnormality was found in the group D.The Hyp level of pulmonary tissue in the group A,B and C was significantly increased compared with the group D(P=0.000);which on 14 d after BMSCs treatment in the group B and C was significantly decreased compared with the group A(P=0.000,P=0.035),and which on 56 d after treatment in the group B was still significantly decreased(P=0.016).Conclusion No matter in the pathological stages of pulmonary alveolitis and fibrosis,BMSCs transplantation may postpone the pathological process of pulmonary fibrosis in silicosis rats.
