Objective To assess the efficacy of the two antiviral medications in preventing cytomegalovirus infection and cytomegalovirus disease in renal transplant recipients.Method We searched articles from Pubmed,EMbase,Cochrane Library,Wanfang Med Online,and China's biomedical journal citation database on line.Randomized controlled trials evaluating preemptive treatment and universal prophylaxis for cytomegalovirus infection and cytomegalovirus disease in renal transplant recipients were reviewed.Two reviewers screened studies and assessed study quality according to the study population,intervention measure and results.Finally data from included studies were subjected to meta-analysis.Result Six studies involving total 752 renal transplant recipients were included in this review.Compared with preemptive treatment,universal prophylaxis significantly reduced the risk of cytomegalovirus infection at 3 rd and 12 th month,and the risk of cytomegalovirus disease at 12 th month after transplantation (RR =12.13,95 % CI.6.59~22.36,P<0.05; RR =2.21,95%CI:1.62~3.01,P<0.05; RR=1.79,95%Chl.22~2.63,P<0.05).There was no statistically significant difference in the incidence of other opportunistic infection and acute rejection.Conclusion Universal prophylaxis was more effective than preemptive treatment in preventing CMV infection and CMV disease in renal transplant recipients.

Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.

Objective: To investigate chronic kidney disease (CKD) and its risk factors in people receiving physical examination. Methods: hTis retrospective study included people over 20 years old who had physical examination in the Health Management Center of Third Xiangya Hospital from Janurary 2008 to June 2011. CKD and its risk factors as well as questionnaire were recorded. hTe risk factors were analyzed by multivariate logistic analysis. CKD was deifned by kidney damage (microalbuminuria≥30 mg/L) and/or hematuria and/or reduced kidney function [evaluate glomerular ifltration rate (eGFR)<60mL/(min.1.73 m2)]. We counted eGFR according to the modiifcation of diet in renal disease (MDRD). Results: A total of 5 708 physical examination reports were included. The detection rate of albuminuria, reduced renal function and hematuria was 25.0%, 1.7% and 1.1%. hTe detection rate of CKD was 25.6%, and detection rate of CKD stage 1-5 was 17.8%, 6.7%, 1.1%, 0 and 0, respectively. Multivariate logistic analysis indicated that diabetes mellitus, hypertension, hypercholesterolemia, male, age, and smoking were the risk factors for CKD. Increasing physical activity was the protective factor against CKD. Conclusion: High prevalence of CKD in people receiving physical examination is found in Changsha, especially stage 1 and 2 CKD. Physical examination is important to screen CKD. Stopping smoking, control of blood glucose, blood pressure, blood lipids and increasing physical activity may help reduce the prevalence of CKD.

OBJECTIVE:To improve the content determination for polygala xanthone Ⅲ in Polygalae Radix contained in Chi-nese Pharmacopoeia (2010 edition). METHODS:HPLC was performed on the column of Hypersil BDS C18 with mobile phase of acetonitrile-0.05% phosphoric acid(gradient elution)at a flow rate of 1.0 ml/min;detection wavelength was 320 nm,column tem-perature was 25℃,and the injection volume was 10μl. RESULTS:The linear range of polygala xanthoneⅢwas 0.029-0.928 μg/ml (r=0.999 1);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recovery was 94.66%-100.90%(RSD=2.46%,n=6). CONCLUSIONS:The method is simple,stable and reproducible. Although the determination time is prolonged,it has improved the accuracy and it is more suitable for the content determination of polygala xanthoneⅢin Polygalae Radix.

Objective To discuss the relationship between repetitive variable deceleration with a short interval (RDSI) in labor and neonatal acidosis.Methods One hundred and seventy-seven electronic fetal heart monitoring (EFM) patterns within one hour preceding delivery in term singleton pregnancies were collected in Peking University Third Hospital between February 2011 to October 2013.Continued EFM were recorded before delivery.Analysis was conducted on general information of both mothers and babies,including pregnant complications,duration of labor,cord and placental factors,nature of amniotic fluid,Apgar score and neonatal cord blood gas.RDSI was defined as that over 50% intervals between two decelerations (the end of the last deceleration to the beginning of the next one) ≤ 60 s which appeared repetitevly in a period of 20 minutes.Independent sample t test,rank sum test,Chi-square test and Fisher's exact test were applied for statistics and receiver operating characteristic curve was obtained from the information of those with RDSI.Results Twenty-four of the 177 women with RDSI were assigned to the study group (24 cases,13.6%) and the rest 153 cases without RDSI to the control group.Background information of women in the two groups was comparable according to the maternal age,gestational weeks at delivery and duration of labor (all P > 0.05).The occurrence of meconium stained amniotic fluid in the study group was higher than that of the control group [16.7% (4/24) vs 5.2% (7/153),x2=5.204,P=0.045],while the pH and base excess value of the neonatal blood gas in the study group were lower [7.20 (7.13-7.28) vs 7.29 (7.25-7.33),Z=-4.490;-6.10 (-4.67 to-9.62) mmol/L vs-3.20 (-4.90 to-1.55) mmol/L,Z=-5.044;P ≤ 0.01] resulting a higher rate of neonatal acidosis [50.0%(12/24) vs 7.8% (12/153),x2=31.456,P < 0.01].No significant difference was found in the incidence of neonatal asphyxia between the two groups.The area under the curve was 0.774 (95%CI:0.579-0.969).Conclusion RDSI in labor might indicate a high risk of neonatal acidosis.
