1.Current status on the intestinal barrier dysfunction in HIV infection
Parenteral & Enteral Nutrition 2017;24(4):244-248
Highly active antiretroviral therapy (HAART) can effectively suppress thehuman immunodeficiency virus (HIV) replication andsignificantly reduce morbidity and mortality of HIV-infectedpatients,which howevercan't completely remove the virus,and eventually progressinto chronic viral-infection disease.Chronic HIVinfection destroys host immune system,leading to intestinal barrier damage,intestinal mucosal dysfunction,microbial translocation,and further accelerates the disease progress.The reconstruction of intestinalmicroflora balance and improvement of intestinal mucosa function areessential to reestablish the host immune system.This paper will review the current research advanceson intestinal barrier damage of HIV infection and gut-target therapy of AIDS.The aim is to provide valid evidences for further research targeting improvement of treatment strategiesandreduction of morbidity and mortality in HIV infection.

Journal of Acupuncture and Tuina Science 2003;1(1):42-43
Yaoyangguan ( GV 3 ), Shiqizhui ( Ex-B 8) and Yanglingquan (GB 34) were selected as main points and a three-part needle insertion technique was used to treat 32 cases of lumbar intervertebral disc protrusion. The curative rate was 96.9%. Deep puncture is the key to the treatment.
3.Alarm failure and its countermeasure when measuring high-concentration enzyme by biochemical analyzer
Chinese Medical Equipment Journal 1989;0(02):-
Modern fully automatic biochemical analyzer makes enzyme measurement accurate, specific and practical, but alarm failure happens sometimes and thus determinate error appears. To find out the inducement to alarm failure, Olympus AU2700 and ADVIA 1650 fully automatic biochemical analyzer are used to measure the serum liver enzyme from 450 cases of post-liver-transplantation patients.

Objective To investigate the number and activity changes of endothelial progenitor cells(EPCs) in hemodialysis patients,and explore its correlation with the risk factors of coronary heart disease.Methords Total mononuclear ceils(MNCs) were isolated from peripheral blood of patients with chronic renal failure in long-term hemodialysis and from a normal control group by Ficoll density gradient centrifugation and then were plated on humanfibronectin-coated dishes.Mter 7 days of culture,EPCs were characterized as adherent cells by double staining with FITC-UEA-I and DI-LDL,and were further identified by the expression of CD34,CD133 and KDR with flow cytometry.EPCs migration was determined with modified Boyden chamber assay.EPCs adhesive assay was performed by replanting EPCs on humanfibronectin-coated plates and then counting the adherent cells.The relationship of the EPCs' number and activity with Framingham Risk Score of ten years was also be assessed.Results Number of EPCs and the migratory & adhesive capacity were significantly lower in patients than in the control(P

Objective To explore the expressions of histamine receptor subtypes (H1, H2, H3, H4 receptor) in children's mid-urethral striated muscles and during mouse C2C12 striated myogenesis.Methods Children's mid-urethral striated muscle samples were paraffin embedded and tissue sections were made, then immunohistochemical staining was used to check H1, H2, H3, H4 receptors.C2C12 myogenesis was induced, the early differentiation early markers of desmin, middle marker of myogenin, late marker of myosin heavy chain and histamine 4 receptor subtype mRNA were checked by quantitative real-time polymerase chain reaction.Immunofluorescence staining was done to check 3 differentiation markers and histamine H3 receptor protein.Results During myogenesis, the expression of desmin mRNA in the differentiation of 2,4,6 days were 12,68,60 times as many as that of the undifferentiated myoblasts;the expression of myogenin mRNA in the differentiation of 2,4,6 days were 631,1 408,914 times as many as that of the undifferentiated myoblasts;the expression of myosin heavy chain mRNA in the differentiation of 2,4,6 days were 7 718,9 448,286 288 times as many as that of the undifferentiated myoblasts.The expression level of H1 receptor mRNA in the differentiation of 6 days was about 25% to undifferentiated cells;the expression of H2 receptor mRNA in undifferentiated cells and differentiated cells groups had no significant difference (F =1.47, P > 0.05);the expression of H3 receptor mRNA in the differentiation of 2,4,6 days was 28,103,198 times to undifferentiated cells;H4 receptor mRNA was not detected.In immunofluorescence staining, H3 receptor protein staining intensity increased with the differentiation.Immunohistochemistry of pediatric urethral striated staining indicated that H1, H2, H3 receptor staining was positive,H1 receptor showed strong positive staining, H3 receptor moderate positive staining,and H2 receptor showed weak positive staining.Conclusions Histamine receptor subtypes of H1 receptor, H2 receptor and H3 receptor were found during mouse striated myogenesis and in the children's mid-urethral striated muscles.The increasing expression of H3R with myogenesis might indicate it plays a role in mature striated muscle cells.

Objective To observe the effect of comprehensive community intervention on cardiovascular risk factors in metabolic syndrome (MS) high risk group.Methods One hundred MS high risk patients were divided into intervention group (50 patients) and control group (50 patients) by random digits table.The intervention group accepted intervention on health education,health action,health habit and individual intervention on drug.The control group accepted natural intervention.The changes of waistcircumference,body mass index (BMI),blood pressure,fasting plasma glucose (FPG),lipids and serum uric acid (UA) were observed.Results In intervention group,the number of physical exercise,alimentary control and medication compliance increased 12%,16% and 18%,and the number of smoking and alcohol drinking decreased 8% and 6%.But in control group,the number of physical exercise,alimentary control,medication compliance increased 2%,0 and 4%,and the number of smoking and alcohol drinking decreased 4% and 2%.There was significant difference (P< 0.05).Before treatment,the level of waist circumference,BMI,systolic pressure,diastolic pressure,FPG,total cholesterol,triacylglycerol,high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C) and UA between two groups had no significant difference (P > 0.05).After 1 year's intervention,except HDL-C,the level of other index had significant difference between two groups (P < 0.05 or < 0.01).Conclusion Comprehensive community intervention can improve the status of obesity and dyslipidemia,and reduce blood pressure,plasma glucose and UA.

Objective To summarize our experience on laparoscopic splenectomy with amputation of the secondary spleen pedicle. Methods From September 2006 to May 2007, laparoscopic splenectomy with amputation of the secondary spleen pedicle was performed on 13 patients, including 5 cases of traumatic spleen rupture, 2 idiopathic thrombocytopenic purpura, and 6 hypersplenism. Results All the operations were completed under a laparoscope without using hand-assisted procedures. The intraoperative blood loss was 50-800 ml (mean, 350 ml), and the operation time was 150-300 min (mean, 210 min). No complications occurred during and after the operation. The average postoperative hospital stay was 5-9 d (mean, 7.5 d). The patients were followed up for 1-6 months, during which all the patients had normal platelet count. Conclusions Laparoscopic splenectomy with amputation of the secondary spleen pedicle is a feasible, minimally invasive, safe and low-cost procedure.

Objective To study the roles of fatty acid transport protein 4 (FATP4) in rat model of nonalcoholic fatty liver. Methods The fatty liver rat model of high fatty diet (H) was established with a control group (C). The expression of FATP4 genes in fatty liver rats was examined by semi-quantitative reverse transcription and polymerase chain reaction (RT-PCR) and Western blotting. Results In group H, protein and mRNA expressions of FATP4 increased at 2 week, especially at 12 week after high fatty diet (P
