Pediatric liver transplantation has long been developed in the western world.Currently,favorable outcomes after liver transplantation have been achieved in pediatric recipients and the postoperative 5-year survival rate reached 80％ in western transplantation centers.In the mainland China,pediatric liver transplantation started quite recently and there is still a big gap compared with western centers.In addition,there is unbalanced development between adult and pediatric recipients due to surgical difficulties and undesirable outcomes following pediatric liver transplantation.The operation methods of pediatric liver transplantation include whole liver transplantation,reduced-size liver transplantation,living donor liver transplantation and split liver transplantation.Perioperative complications of pediatric liver transplantation mainly include portal vein thrombosis,hepatic artery thrombosis,intra-abdominal bleeding,infections,rejection,bile leakage and biliary strictures.While the long-term complications are infections,post-transplantation lymphoproliferative disorders,acute and chronic rejections caused by poor compliance with immunosuppressive therapy.Perioperative complications have been reduced recently thanks to improvement of surgical techniques.With the highly-prolonged survival period,long-term postoperative complications have been playing a significant role in recipients' survival rates.Management of long-term follow-up and compliance has been the next focus of pediatric liver transplantation.

Objective To investigate and compare the impacts of health education and psychological intervention on the clinical effects of patients with hypertension. Methods 102 hypertension cases were collected and were randomly divided into three groups, health education group (36 cases), psychological intervention group (30 cases) and comparison group (36 cases). Compliance with prescription,anxiety level and blood pressure were observed both before and after the health education and psychological intervention. Result After health education,compliance with prescription in health education group was significantly improved ( P ＜ 0. 01 ), and blood pressure control of health education group was more preferable than the comparison group ( P ＜ 0. 01 ). After psychological intervention,anxiety level in psychological intervention group was significantly decreased ( P ＜ 0. 05 ), and blood pressures control of psychological intervention group was more preferable than the comparison group ( P ＜ 0. 01 ). Blood pressures had no statistical significance between health education group and psychological intervention group. Conclurion Health education could improve compliance with prescription, and paychological intervention could improve patients' mentl health, and both of them were conducive to the control of blood pressure of patients.

Objective To investigate the chnical effect of levonorgestrel-releasing intrauterine system(LNG-IUS) in patients with adenomyosis.Methods A total of eighty patients with adenomyosis were enrolled and underwent LNG-IUS insertion.The degree of dysmenorrhea,amount of menorrhea,size of the uterus,endometrial thickness,hemoglobin as well as hormonal changes and adverse reaction before treatment and after treatment for 3,6,12 months were compared.Results After treatment for3,6,12months,the amount of menorrhea was reduced [(52.4 ± 8.4)％,(22.6 ± 9.8)％,(14.8 ± 8.6)％ vs.(100.0 ±0.0)％],the scores of dysmenorrhea was reduced [(1.2 ± 0.5),(0.8 ± 0.4),(0.3 ± 0.2) scores vs.(2.4 ±0.6) scores],the level of hemoglobin was increased [(104.4 ± 11.4),(109.2 ± 12.6),(118.8 ± 13.4) g/L vs.(88.6 ± 16.5) g/L],the endometrial thickness was thinner [(6.3 ± 1.4),(3.6 ± 0.8),(1.8 ± 0.5) mm vs.(9.2 ± 2.8) mm],the size of the uterus was reduced [(156.8 ± 56.8),(142.4 ± 48.9),(126.6 ± 36.5)cm3 vs.(172.6 ± 62.5) cm3],there was significant difference compared with that before treatment (P ＜ 0.05).After treatment for 3,6,12 months,the levels of folhcle-stimulating hormone,luteinizing hormone and estradiol had no significant difference compared with those before treatment (P ＞ 0.05).After treatment for 3,6,12 months,the level of cancer antigen 125 was significantly reduced compared with that before treatment [(34.6 ± 11.6),(16.6 ± 9.8),(11.7 ± 6.4) kU/L vs.(62.4 ± 24.3) kU/L].Conclusiom The LNG-IUS has exact therapeutic effect in treatment of adenomyosis,and has little influence on ovarian function.It is worth of using in clinic.

Objective To explore the clinical efficacy of ethinylestradiol and cyproterone acetate (Diane-35) combined with mefformin in patients with polycystic ovary syndrome (PCOS).Methods One hundred and sixty patients with PCOS were divided into control group and observation group by random digits table method with 80 cases each.Patients in the control group were given Diane-35 only,while patients in the observation group were given Diane-35 combined with metformin.The triglycerides (TG),total cholesterol (TC),low density lipoprotein cholesterol (LDL-C),fasting insulin (FINS),fasting blood glucose (FBG),follicle-stimulating hormone (FSH),luteinizing hormone (LH) and testosterone (T) of patients in the two groups were measured before treatment and after treatment 6 months,the rates of pregnancy and abortion were recorded.Results TC,LDL-C,FINS,FBG,FSH,LHt and T of both the 2 groups after treatment decreased obviously than before treatment,and TG in observation group decreased obviously than before treatment,there were statistical differences (P ＜ 0.05).There was no statistical difference in TG in control group between before treatment and after treatment (P ＞ 0.05).After treatment,TG,FINS,FBG,LH in observation group were lower than those in control group [(1.0 ± 0.2) mmol/L vs.(1.6 ± 0.8) mmol/L,(15.2 ± 6.3) mU/L vs.(18.9 ± 6.2) mU/L,(4.5 ± 1.1) mmol/L vs.(5.1 ± 0.9) mmol/L,(6.3 ± 3.0) U/L vs.(7.4 ± 2.9) U/L],there were statistical differences (P ＜ 0.05).After treatment,the rate of pregnancy in observation group was higher than that in control group [61.2％(49/80) vs.42.5％(34/80)],there was statistical difference (x2 =5.633,P＜ 0.05).The rote of abortion in observation group was lower than that in control group [6.1％(3/49) vs.17.6％(6/34)],but there was no statistical difference (x2 =1.694,P ＞ 0.05).Conclusion The clinical effect of Diane-35 combined with metformin in patients with PCOS is better than Diane-35 only.

Objective To explore the influence of shenmai injection on C-reactive protein(CRP) and homocysteine(Hcy) of patients with non-ST-segment elevation acute coronary syndrome.Methods 96 patients with nonST-segment elevation acute coronary syndrome were randomly divided into the control group(48 cases) and the observation group(48 cases).The patients in the control group were treated through the conventional treatment,while the patients in the treatment group were treated by shenmai injection based on the conventional therapy.They were all treated for 14 days.CRP and Hcy were detected before and after treatment.Results The total effective rate of the observation group was 95.8％,which was significantly higher than 87.5％ of the control group (x2 =4.760,P ＜0.05).The plasma levels of CRP and Hcy were all decreased after treatment in both two groups.The CRP and Hcy in the observation group were significantly lower than those in the control group (t =2.927,2.624,all P ＜ 0.05).Conclusion Shenmai injection can significandy decrease the plasma levels of CRP and Hcy in patients with non-ST-segment elevation acute coronary syndrome.

MicroRNA (miRNA) is a kind of small non-protein coding RNA and can negatively regulate the expression of target genes at the transcriptional level. In tumors miRNA can act as oncogenes and tumor suppressor genes, and its deregulation in tumors may be a possible reason for tumor progression. Several studies have established the potential usefulness of miRNA as therapeutic targets for tumor metastasis.

Objective To evaluate the short-term efficacy and adverse effects of capecitabine as adjuvant chemotherapy of gastric cancer after resection in aged patients. Methods Sixty aged patients with gastric cancer (Ⅱ-Ⅲstage) after resection were randomized to two groups: the high dose group,in which 30 patients were treated least 6 therapeutic cycles (3 weeks for 1 cycle). Efficacy and adverse effects were assessed after 2 cycles. Results Two years' survival was 80% (24/30) in the high dose group and 77% (23/30) in the low dose group (χ2=0.54,P=0.45). The recurrence-free survival time was 19.2 months and 19.0 months respectively (χ2=0.82,P=0.36). Patients in the high dose group experienced more significant nausea/vomiting (Ⅰ-Ⅱ grade) than patients in the low dose group (χ2 = 9.82,P=0.02). However,there was no significant difference on grade Ⅲ-Ⅳ nausea/vomi-ting between the 2 groups(χ2=0.34,P=0.71). The incidence of grade Ⅰ-Ⅳ mucositis,hyperbilirubinemia and hand-foot syndrome (HFS) in the high dose group were higher than in the low dose group( P=0. 04,0. 02 and 0.04,respectively). There was no difference on weakness,lack of appetite and neutropenia between the two groups. in aged patients with similar efficacy and better tolerance of adverse effects compared to capeeitabine [2500 mg/

Objectives To explore the relationship of serum miR-30a and cardiac function in children with congenital heart disease (CHD), and the diagnostic value of serum miR-30a to heart failure. Methods From January 2013 to June 2013, 65 children with CHD were enrolled, and divided into the HF group (patients with heart failure, n=40) and the Non-HF group (patients without heart failure, n=25) according to modified Ross score. The serum miR-30a expression level was quantified by real-time PCR. Left ventricular ejection fraction (LVEF) was tested by echocardiography. The correlation between miR-30a and modified Ross score and LVEF were evaluated with Spearman's analysis. The area under the receiver-operating characteristic (ROC) curve for miR-30a was examined. Results The expression level of miR-30a in HF group was higher than that in Non-HF group, the LVEF was lower in HF group than that in Non-HF group (all P<0.001). The serum miR-30a level was positively correlated with modified Ross score (r=0.63, P<0.01) and negatively correlated with LVEF (r=-0.32, P<0.01). According to ROC analysis, the AUC of miR-30a for detection of HF was 0.7440. Conclusion The expression level of serum miR-30a was closely correlated with the cardiac function, which can be as a biomarker for indicating the heart failure in CHD.
