Objective To evaluate the effect of coagulation function changes on the incidence of acute kidney injury (AKI) after liver transplantation. Methods Clinical data of 245 liver transplant recipients who met the inclusion and exclusion criteria were retrospectively analyzed. According to the incidence of AKI after liver transplantation, all recipients were divided into the AKI group (n=99) and non-AKI group (n=146). The incidence of AKI after liver transplantation was summarized. Perioperative parameters of the recipients were collected. The risk factors of AKI after liver transplantation were assessed by univariate and multivariate analysis. Results Among 245 recipients undergoing liver transplantation, 99 cases developed AKI after operation with an incidence rate of 40.4%. Preoperative serum creatinine levels of the recipients and the in-hospital fatality were relatively high in the AKI group (all P < 0.05). Compared with the recipients in the non-AKI group, those in the AKI group presented with significantly higher liver function parameters within postoperative 24 h, significantly decreased levels of stage Ⅱ coagulation parameters including coagulation factorsⅤ, Ⅶ, Ⅸ, Ⅹ, Ⅻ and protein S, protein C and antithrombin Ⅲ, evidently elevated prothrombin time international normalized ratio (PT-INR), remarkably increased stage Ⅲ coagulation parameters including D-dimer and fibrin degradation product (FDP) levels and considerably decreased fibrinogen (FIB) level (all P < 0.05). Thrombelastogram showed that the R value was increased, the α angle was decreased and the coagulation time was prolonged in the AKI group (all P < 0.05). Logistic regression analysis demonstrated that the increased R value of postoperative thrombelastogram [odd ratio (OR) 1.116, 95% confidence interval (CI) 1.018-1.223, P=0.019], and decreased levels of antithrombin Ⅲ (OR 0.974, 95%CI 0.955-0.993, P=0.007) were the independent risk factors of incidence of AKI after liver transplantation. Conclusions The incidence of AKI after liver transplantation is high, which is associated with the coagulation function changes of the recipients. Decreased coagulation factor activity (increased R value) and declined antithrombin Ⅲ level are the independent risk factors of AKI in liver transplantat recipients.

Objective To analyze the effect of multi-disciplinary health education team on disease related knowledge and life style of patients with hyperuricemia.Methods Totals of 800 cases with hyperuricemia between January 2011 and June 2012 were randomly divided into observation group (n =400) and control group (n =400).Observation group received the intervention of multi-disciplinary health education team,while control group received the routine health education.Blood uric acid level were monitored and compared between two groups before and after health education.Through the questionnaire survey form,before and after health education,knowledge of two groups about prevention and control of hyperuricemia and life habits change situation were studied.Results Comparison of two groups of hyperuricemia curative effect,observation group was obviously higher than that of the control group [(91.25 ％ vs 53.00％) ;Z =-5.930,P ＜ 0.05)].No significant difference was found in the hyperuricemia knowledge awareness about prevention and control between two group before the intervention (P ＞ 0.05),while after the intervention,the knowledge awareness rote of health education group was significantly higher than that of the control group (94.50％ vs 66.25％ ;x2 =5.343,P ＜ 0.05).The reasonable diet proportion (96.75％ vs 53.25％),the proportion of drinking less than 200 ml (94.00％ vs 58.75 ％),the proportion of moderate exercise (91.25％ vs 66.75 ％) between two group were significant difference (x2 =5.231,5.038,4.987 ; P ＜ 0.05).Conclusions The intervention of multidisciplinary health education team on patients with hypemricemia can achieve the effect of prevention and control of hyperuricemia,and promote the change of patients' way of life,improve their awareness for hyperuricemia harmfulness,and improve their medical treatment compliance.

Objective To discuss the health education needs of patients with hyperuricemia among Henlan district in Guangdong province so as to improve the effect of health education.Methods Adopted self-designed questionnaire survey forms,we conducted the investigation about content,time and way needs of the health education on 763 patients with hyperuricemia among coastal town in Guangdong from January to December 2011.Results Of the 733 distributed questionnaires,totally 689 questionnaire were retrieved,the effective resporvse rate was 94％.Influences of patient's age,time length of disease and time to select the health education on the patient' s demand of health education had the statistical significance (x2 =23.96,10.32,543.81; P ＜ 0.05).The demand of old patients regarding the health education reached 92.9％,and the demand factor of the patients with disease for 1-3 months about the health education was 93.4％,77.2％ of patients thought that the best time for receiving the health education was afternoon.And there was no significance difference in the education degree and the health education needs different of the patients (P ＞0.05).The choices of health education content needs of the patients were that 91％ of patients selected the prevention and treatment method and effect of the hyperuricemia,92.5％ of patients selected habits and customs which may easily cause the hyperuricemia,90％ of patients selected damage of the hyperuricemia.The choices of health education ways were as follows:91％ of patients selected the health knowledge lecture,90％ of patients selected the communication between doctor and patient,89％ of patients selected the introduction of ward mate' s experience.Conclusions Through the analysis on health education content and way needs of farmer group patients with hyperuricemia,more scientific,convenient and efficient health education services can be provided for patients.

OBJECTIVETo explore the mucosal protective effect on the quality of gastric ulcer healing.

METHODSGastric ulcers were induced in male rats by serosal application of acetic acid. Rats were gavaged for 14 days with saline, omeprazole (OME), teprenone (TEP) and TEP plus OME starting 3 days after ulcer induction. Then the tissues and blood samples were obtained and measured.

RESULTThe lower ulcer index (UI) and increased ulcer inhibition rate were observed in OME and OME+TEP groups. In TEP and OME+TEP groups, restored mucosa thickness increased, cystically dilated glands decreased, microvessels in connective tissue increased, the secretion of mucus, hexosamine, PGE(2), bFGF were enhanced, the expression of EGFR was increased.

CONCLUSIONTEP can improve the quality of gastric ulcer healing, when combined with OME,the effect is more marked.

To understand the infections and molecular biological characteristics of different human rhinovirus (HRV) genotypes -A, B, C, especially C in children with acute respiratory tract infections (ARI) in Beijing. Seven hundreds and three respiratory tract specimens were collected from children with ARI during Jan. 2011 to Dec. 2011. Semi-nested PCR was developed for detecting HRVs. Gene fragment of VP4/VP2 capsid protein amplified from HRV positive specimens was sequenced and analyzed by software DNAStar, the phylogenetic tree was then constructed by MEGA 5. 05. Among these 703 specimens tested, 54 (7.7%, 54/703) were HRV positive, including 25 (46.3%, 25/54) positive for HRV-A, 8 (14. 8%, 8/54) for HRV-B, 21 (38. 9%, 21/54) for HRV-C determined by sequence analysis. Most of these children (94. 4%00, 51/54) infected with HRVs were younger than 5 years old, and the highest positive rate was shown in group younger than 1 year (11. 4%). These patients positive for HRVs were diagnosed as bronchiolitis (23.1%), asthma (20.0%), pneumonia (1.0%), bronchitis (4.4%) and upper respiratory tract infections (4. 1%). Sequence analysis of VP4/VP2 gene fragment revealed that 70. 0% to 100. 0% nucleotide identity was shown among the sequences within the same HRV genotype, and 55. 5% to 65. 8% nucleotide identity among the sequences from different HRV genotypes. In conclusion, HRVs, especially HRV-C, are important pathogens for children with ARI in Beijing. The prevalence of HRV-C is similar to that of HRV-A, higher than that of HRV-B. High sequence variation among different HRV genotypes was indicated in this study.

BACKGROUNDAlthough human parainfluenza virus (HPIV) has been determined as an important viral cause of acute respiratory infections (ARIs) in infants and young children, data on long-term investigation are still lacking to disclose the infection pattern of HPIV in China.

METHODSNasopharyngeal aspirates were collected from 25,773 hospitalized pediatric patients with ARIs from January 2004 through December 2012 for respiratory virus screen by direct immuno-fluorescence assay.

RESULTSOut of these specimens, 1675 (6.50%, 1675/25,773) showed HPIV positive, including 261 (1.01%, 261/25,773) for HPIV1, 28 (0.11%, 28/25,773) for HPIV2, and 1388 (5.39%, 1388/25,773) for HPIV3, 2 of the samples were positive for both HPIV1 and HPIV3, and 36 were co-detected with other viruses. The positive rates of HPIVs were higher in those younger than 3 years old. HPIV3 was detected from all age groups, predominantly from patients under 3 years of age, and the highest frequency was found in those 6 months to 1-year old (352/4077, 8.63%). HPIV3 was the dominant type in each of the years detected between May and July. HPIV1 showed a peak in every odd year, mainly in August or September. HPIV was detected most frequently from patients with upper respiratory infection (12.49%, 157/1257), followed by bronchitis (11.13%, 176/2479), asthma (9.31%, 43/462), bronchiolitis (5.91%, 150/2536), pneumonia (6.06%, 1034/17,068), and those with underlying diseases (1.0%, 15/1506). HPIV3 is the dominant type in these six disease groups referred above, especially in the asthma group.

CONCLUSIONSHPIV is one of the important viral causes of ARIs in infants and young children in Beijing based on the data from the hospitalized children covering a 9-year term. HPIV3 is the predominant type in all these years and in most of the disease groups. HPIVs with different types show different seasonality.
