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.

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.

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.

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 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.

Objective:To share the experience of clinical cooperation of physicians and clinical pharmacists in the treatment of one case of rodenticide poisoning. Methods: One case of rodenticide poisoning was early diagnosed by physicians according to the con-sciousness disorder and coagulation dysfunction. Clinical pharmacists participated in the drug treatment actively through providing vita-min K1 at the dose of 30 mg·d-1 as the treatment dose and monitoring the effectiveness. Toxicology analysis was recommended, and 718 ng·ml-1 bromadiolone was found out in the blood samples. According to the long half-life of bromadiolone, the initial duration of treatment was set at 2-3 months, while follow-up plan and final duration of treatment were defined based on coagulation parameters and poison concentration monitoring results. Results:The patient recovered rapidly after hospitalization due to the cooperation of physicians and clinical pharmacists through quickly correcting diagnosis of physicians and actively participating in medication of clinical pharma-cists. After the 3-month treatment, the coagulation parameters of the patient were normal and the patient was discharged with follow-up. Conclusion:The collaboration of physicians and clinical pharmacists leads to the optimal regimen with early, full dose and long course of vitamin K1 therapy.

Objective To study pathogensand diagnostic value of beta2-microglobulin(?2-MG) in cerebrospinal fluid(CSF) in children with aseptic meningitis(AM).Methods Polymerase chain reaction (PCR) or reverse transcription-PCR (RT-PCR) assay,enzyme linked immunosorbent assay (ELISA) and passive particle agglutination were employed respectively to detect herpes simplex virus type-1(HSV-1) DNA,enterovirus(EV) RNA in CSF and the specific antibodies of HSV-1 and mycoplasma pneumonia(MP) in blood and CSF from 80 children with AM (AM group) and 20 cases of complete remission acute leukaemia(control group).Children with AM were divided into the EV meningitis group,HSV-1 meningitis group and MP meningitis group according to respective diagnostic criteria.The levels of ?2-MG in CSF from all groups were detected by radio immunoassay.SPSS 13.0 software was used to analyze the data.Results The infection rate of EV,HSV-1 and MP were 52.5%,11.25%and 5.0%,respectively in children with AM.The infection rate of EV was highest.The sensitivity of PCR was higher than ELISA.There could be false negative PCR results in bloody CSF specimens with HSV-1 DNA.The levels of ?2-MG in CSF was significantly higher in children with AM than that in control group(P

Sulfogalactosylglycerolipid (SGG) is the main glycolipid in male mammalian germ cells, which is selectively and highly expressed in mammalian testes and helps form the lipid bilayer of cell membrane. In the process of spermatogenesis, SGG is involved in the meiosis of spermiocytes. Either deficiency or accumulation of SGG will lead to male infertility. SGG homeostasis in the testis is the premise of normal spermatogenesis. In the process of sperm-zona binding, SGG becomes a component of lipid raft and provides a platform for signal transduction. The SGG binding protein plays a role in sperm-egg recognition and membrane fusion. SGG has a great research value and application prospect in male reproduction.
