Biliary atresia (BA) is the most common cause of persistent jaundice in infant,it can rapidly advance to biliary cirrhosis and death.Surgical treatment in time can decrease mortality,so it is essential to be differentiated from other diseases as early as possible.Main diagnosis methods of BA include clinical feature of patients,liver biopsy,and high-frequen cy ultrasonography,MR cholangiopancreatography (MRCP),hepatobiliary scintigraphy.High-frequency ultrasonography is superior to other methods with high diagnostic specificity and sensitivity.The progresses of ultrasonography in diagnosis of BA were reviewed in this article.

Objective To explore the risk factors for community-acquired pneumonia (CAP) in the elderly,in order to provide the basis for clinical prevention and treatment.Methods 168 elderly patients with CAP (observation group) and 100 elderly patients without CAP (control group) were chosen from our hospital from Jan.2013 to Dec.2014.The clinical data were investigated,and the risk factors for CAP were analyzed.Results Single factor analysis showed that there were significant differences between the two groupsin serum protein level,pets-raising,smoking,dust exposure,bronchial disease,renal dysfunction and diabetes mellitus (all P＜0.05).Multivariate logistic regression analysis showed that serum protein level,pets-raising,smoking,bronchial disease and diabetes were the independent risk factors for CAP in the elderly (OR=2.793,2.578,3.017,3.168 and 2.643,all P＜0.05).Conclusions The community-acquired pneumonia is related with many risk factors in the elderly.The clinical corresponding prevention and treatment for the risk factors should be developed,which have an important significance in the early diagnosis,early treatment and prognostic improvement in community-acquired pneumonia.

0.05).Conclusion There may be no significant difference in sensory block,motor block and prevalence of adverse effects between injection rates of 0.27 mL/s and 0.04 mL/s in spinal anesthesia with 20 mg isobaric ropivacaine.

ObjectiveTo study the risk factors of childhood functional constipation.MethodsA cross-sectional analysis of risk factors associated with 182 cases of functional constipation in children was conducted from March 2013 to February 2014. ResultsThe male patients were more than females, mainly in preschool children. The risk factors were did not like fruits and vegetables (52.2%), drank less water (44.0%), did not develop the habit of daily bowel movement (39.5%), defecation fear (36.3%), inadequate food intake (25.8%). There were different risk factors in different age stages.ConclusionsFunctional constipation is related to gender, age, diet habits and mental psychology.

OBJECTIVE:To systematically review the efficacy and safety of pituitrin combined with phentolamine versus pitui-trin alone in the treatment of bronchiectasis hemoptysis(BH),and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CJFD,Wanfang and VIP database,the randomized controlled trails(RCT)about pituitrin combined with phentolamine(test group)versus pituitrin alone(control group)in the treatment of BH were collected,and afterdata extract and quality evaluation ,Meta-analysis was performed by using Rev Man 5.2.3 statistics soft-ware. RESULTS:A total of 43 RCTs were included,involving 3 094 patients. Results of Meta-analysis showed the significant effi-cacy [RR=1.50,95%CI(1.38,1.62),P<0.001] and effective rate [RR=1.25,95%CI(1.20,1.30),P<0.001] in test group were sig-nificantly higher than control group,inefficacy [RR=0.29,95%CI(0.23,0.36),P<0.001], hemoptysis stopped or remission time [MD=-2.00,95%CI(-2.43,-1.57),P<0.001],incidence of headache [RR=0.36,95%CI(0.22,0.59),P<0.001],incidence of chest tightness [RR=0.41,95%CI(0.26,0.63),P<0.001],incidence of abdominal pain [RR=0.26,95%CI(0.16,0.43),P<0.001] and incidence of elevated blood pressure [RR=0.28,95%CI(0.14,0.56),P<0.001] in test group were significantly lower than control group,there were significant differences in 2 groups. CONCLUSIONS:Pituitrin combined with phentolamine has better efficacy and safety than pituitrin alone in the treatment of BH. Due to the limit of methodological quality and sample size,it re-mains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

Spermatogenesis is a complex developmental process in which a diploid progenitor germ cell transforms into highly specialized spermatozoa. During spermatogenesis, membrane remodeling takes place, and cell membrane permeability and liquidity undergo phase-specific changes, which are all associated with the alteration of membrane lipids. Lipids are important components of the germ cell membrane, whose volume and ratio fluctuate in different phases of spermatogenesis. Abnormal lipid metabolism can cause spermatogenic dysfunction and consequently male infertility. Germ cell membrane lipids are mainly composed of cholesterol, phospholipids and glycolipids, which play critical roles in cell adhesion and signal transduction during spermatogenesis. An insight into the correlation of membrane lipids with spermatogenesis helps us to better understand the mechanisms of spermatogenesis and provide new approaches to the diagnosis and treatment of male infertility.

Objective: Five phenolic compounds in fruits of Rhodomyrtus tomentosa from six different regiones were measured by HPLC, and the ability of scavenging free radicals of five kinds of phenolics and myrtle fruits extracts in different regions was investigated. Methods: The determination was performed on Inertsil ODS-SP column (150 mm × 4.6 mm, 5 μm), the mobile phase consisted of acetonitrile and 0.1% phosphate aqueous solution with gradient elution program, flow rate was 1 mL/min with 10 μL of sample quantity at 280 nm, and the antiradical efficiency of five phenolic compounds and extrcts were evaluated by DPPH radical scavenging assay. Results: Five kinds of phenolic components showed a good linear relationship, and the precision, stability, repeatability, and sample recovery rate all met the requirements. Five phenolic compounds and extracts had good antiradical efficiency. The IC50 values of the myrtle fruits extracts from Xinfeng, Wengyuan counties in Guangdong province, Nanning, Guilin in Guangxi province, Yunnan province, and Guizhou province were 58.82, 61.57, 17.73, 7.91, 14.77, and 8.11 μg/mL, and the IC50 values of gallic acid, protocatechuic acid, catechin, ellagic acid, and resveratrol were 0.02, 0.04, 0.03, 0.05, and 5.70 μg/mL, respectively. The IC50 of positive control VC was 6.31 μg/mL. Conclusion: Material basis of antiradical efficiency of fruits is preliminary identified and it provides a scientific basis for the comprehensive utilization of the resources of R. tomentosa.

Objective To investigate the effect of meridian massage on the growth and development of premature infants.Methods 60 preterm infants were randomly divided into the observation group and the control group with 30 cases in each group,the control group adopted modified domestic simple meridian massage method,and the observation group increase meridian massage based on the control group,2 times a day and 15 minutes one time.Body weight,length,intake of milk,sleep time,time to regain birth weight,and meconium drained time were eomparel between two groups.Results The observation group was significantly better than the control group in body weight,length,intake of milk,sleep time,time to regain birth weight,and meconium drained time.Conclusions Meridian massage based on the domestic simple touch method plays a significant role in promoting the growth and development of premature infants.
