Objectives:The study was designed to observe the effects of L-arginine(Arg) supplemented enteral nutrition on cellular immunological function in rats with severe head injury.Method:The severe head injury of rats was produced by gas percussion.Thirty rats were divided randomly into 3 groups(n=10): normal control group,enteral nutrition(EN)group and EN+Arg group.Rats in groups EN and EN+Arg were supplemented with tyrosine at the does of 0.8g?kg~(-1)?d~(–1)and Arg at the dose of 0.8g?kg~(-1)?d~(–1)for 7days,respectively.Blood samples were collected after 7 days.PMN phagocytosis rate was observed by phagocytosis Candida albicans count.CD4~(+)cells and CD8~(+) cells were analyzed by SABC.The concentration of serum IL-2 level was measured by radioimmunoassay.Results:Decreased cellular immunolgical function was found on 7~(th) day after severe head injury.However,CD4~(+),CD4~(+)/CD8~(+),IL-2 level and PMN phagocytosis rate in EN +Arg group were better than that in EN group.There was significant difference in each immunological index(P

MicroRNAs(miRNAs) are small non-coding RNAs of 20-24nt(about 22nt) in length that mediate gene expression at the post-transcriptional level by degrading or repressing target messenger RNAs (mRNAs).Angiogenesis plays an important role in occurrence and development of cancers which involves multiple signaling pathways.miRNAs can regulate the signaling pathways in which their target genes are involved.Therefore,to study the miRNAs regulation of tumor angiogenesis slgnaling pathways will contribute to cancer diagnosis and treatment.

The growth rate of the incidence of Barrett's esophagus ranked the second place among all the malignant esophageal tumors,and Barrett's esophagus is a precursor of esophageal adenocarcinoma.The incidence of Barrett's esophagus is closely related to social economic status.In developed countries,the incidence of esophageal adenocarcinoma associared with Barrett's esophagus has been increased rapidly.The risk factors for Barrett's esophagus include gastroesophageal reflux disease,white or Hispanic race,male,age,smoking and obesity.The treatment of Barrett's esophagus mainly include drug therapy,endoscopic therapy and surgical treatment.The efficiency of chemoprevention of Barrett's esophagus still needs to be proved by further randomized clinical trials.

OBJECTIVE:To establish a bacterial endotoxin test for ofloxacin injection METHODS:Interference tests in ofloxacin injection were performed with limulus test agents provided by different factories RESULTS:Ofloxacin injection did not interfer with bacterial endotoxin CONCLUSION:Bacterial endotoxin test can take the place of pyrogen test for ofloxacin injection

OBJECTIVE:To find out the situation of the use of antimicrobials in perioperative patients and to evaluate the rationality of use.METHODS: To make a survey of the use of antimicrobials in 230 surgical patients during the period Dec. 2002 - Apr. 2004, and to evaluate the kinds, frequency, cost - effectiveness ratios, combined administration, course, effectiveness and drug adverse react ions. RESULTS: 100 percent patients had received antimicrobials involving 32 kinds of drug and 8 595 case - time.The cost of consumption of antimicrobials per case was 1 183.5 yuans.The average therapeutic course was 21.89 days.The operation incisions healed by first intention in 230 cases.The cost ratios of total drugs and antimicrobials was 1 : 0.41 .CONCLUSION:The supervision of using antimicrobials in perioperative period must be reinforced.

Objective:To discuss the important role of clinical pharmacists in the prevention of medication errors and rational drug use through medication reconciliation in endocrinology department. Methods: The medication reconciliation was given to the diabetic patients over 70 years old newly admitted in the endocrinology department from January to April 2016, and the consistency and appro-priateness of medication orders were verified and the results were collected and analyzed by the pharmacists. Results: Totally 84 pa-tients were enrolled into the research with the average age of (76. 3 ± 5. 0) and the average number of combined diseases of (3. 5 ± 1. 2). The average medications taken by the patients before the admission were (6. 7 ± 2. 9), and 22. 6% of the patients took tradi-tional Chinese medicines and 4. 76% of the patients took health products. The patients whose medications for 24h needed intervention accounted for 27. 38%, the medications orders needed intervention accounted for 3. 67%, and the intervention success rate of clinical pharmacist was 100%. Conclusion:To the patients over 70 years old with type 2 diabetes and multiple diseases treated with a variety of medications, medication reconciliation in 24 hours can effectively prevent the medication errors and promote the rational drug use.

Objective To investigate serum cancer antigens (CA) 125 expression in different types of ovarian endometriosis and related factors.Methods A total of 182 patients with ovarian endometriosis was collected,then they were divided into two groups:ovarian endometriosis combined with other parts of lesions (A group,88 cases),simple ovarian endometriosis group (B group,94 cases).And selected 100 healthy physical check-up women from the hospital outpatient department were as control group.The serum level of CA125 was detected.The patients' information including body shape,menstrual factors,reproductive activities and disease staging were collected.Chi-square criterion and multivariate binary Logistic regression analysis were completed.Results The serum levels of CA125 in A group,B group and control group were (48.64 ± 33.18),(41.35 ± 23.46),(22.16 ± 13.73) kU/L,respectively,and the positive expression rate of three groups were 64.77％ (57/88),52.13％ (49/94),2.00％ (2/100),respectively,there were significant differences (P ＜ 0.05).The multivariate binary Logistic regression analysis result showed that age of 35-49years,reforming American fertility society of Ⅲ-Ⅳ stage,pelvic adhesion and menorrhalgia were the important factors of positive expression of CA125.Conclusion The serum level of CA125 can be used as the evaluation of the diagnosis and treatment of ovarian endometriosis.

Neonatology probation teaching is one of the difficulties in eight-year program pediatric teaching.There are some problems in the neonatology probation teaching,including partial comprehension of neonatal basic theoretical knowledge,few opportunities of clinical operations and observation,lack of effective physician-patient communication method,defective mastering of neonatal clinics skills.In order to refine the neonatology probation of eight-year program medical students and to improve the quality of hospitals' clinical teaching,an appropriate neonatology clerkship program of eightyear medical students should be investigated.A variety of teaching methods should be applied to enhance students' interest of learning the basic theory.Before entering the neonatal ward,it is necessary for eight-year program medical students to understand the workflow and a standard appraisal system should be established.At the same time,it is essential to strengthen the training of their interpersonal communication skills,clinical thinking and clinical skills.Finally,a standard out-department examination system should be established to evaluate the eight-year program medical students' neonatology learning effect objectively.

0.05),but significant difference existed on the 7th day after injury. The Cor content of group Arg was noticeably lower than that of group EN on each time point(P

OBJECTIVE:To study the compatible stability of potassium sodium dehydroandrographolide succinate injection in six infusions.METHODS:The changes of potassium sodium dehydroandrographolide succinate injection in appearance,pH value,content and insoluble micrones after mixing with six infusions(0.9% NaCl solution,Compound sodium chloride injection,Glucose saline,DX 40 glucose injection,5% glucose injection in glass or plastic containers)were determined respectively.RESULTS:No significant changes were noted for the mixture within 4 h in appearance,pH value and content.Except the micrones in potassium sodium dehydroandrographolide succinate mixed with compound sodium chloride injection were up to the standard(China Pharmacopeia,2005 edition),the micrones in all the other mixtures failed to meet the standard.CONCLUSION:Potassium sodium dehydroandrographolide succinate injection can be used in combination with compound sodium chloride injection.
