Objective:To understand the progress in AIDS/HIV research over the last 10 years through a bibliometric approach.Methods:The literatures were searched in Web of Science citation database(1996-2005)using the following terms:"HIV*"or"AIDS"or"human immunodeficiency virus*"or"acquired immune deficiency syndrome".The searching results were analyzed by the Derwent Analytics software concerning the article numbers and the total citations by countries,institutes and authors,and AIDS/HIV magazine distribution,in an effort to discover AIDS/HIV research progress in and outside China in recent years.Results:The annual numbers(about 12000)of AIDS/HIV articles published in Web of Science had little change from 1996 to 2005.The U.S.played a leading role the AIDS/HIV research in the world;China has made a great progress in AIDS/HIV research in the recent years,but still lagging far behind western countries like the U.S.,England, France,Italy,German,etc.The etiology,pathogenesis of AIDS,the HIV coreceptors(CXCR4 and CCRS),and HIV drugs and vaccines were the focuses of AIDS/HIV research in the world in the recent years;meanwhile,the isolation,purification and function of antiviral and antifungal proteins from plants,HIV coreceptors(CXCR4 and CCR5),and APOBEC3G protein were the focuses in China.Conclusion:Due to the worldwide epidemic of AIDS/HIV and the increasing attention from scientists,the prevention and treatment of AIDS/HIV had been a research focus in recent years.The research of AIDS/HIV in China has been progressing rapidly,but still lagging behind its international peers.The research contents and focuses of China are different from the international ones.

Objective To explore the MSCT characteristics of gastric schwannoma (GS).Methods 1 6 patients with pathologically verified GS were included in our study.The MSCT images were analysed retrospectively.Results 1 6 participants were determined with solitary nodule,which located in gastric antrum,body and fundus,respectively with 5 cases,10 cases and 1 case.13 of them showed morphologically as round or ovoid shape,while 3 of them grew irregularly lobulated lesion.For their growth pattern,1 3 tumors presented as bilateral growth,1 lesion appeared intra-cavitary growth,1 grew outside the cavity fields.However,1 case was hard to confirm the growth pattern due to the gastroduodenal intussusception.14 tumors appeared uniform density,1 showed a little necrosis and 1 had dotted calcification,all the lesions were emerged as progressive enhancement with inhomogeneous feature.Conclusion GS mostly located in gastric body or antrum,with round or ovoid appearence,well-defined border,and bilateral growth pattern,necro-sis and calcification are rare,enhanced progressively with homogeneous feature,with no surrounding invasion and metastasis.

Objective To systematic review the methodological quality of guidelines for Guillain-Barré syndrome (GBS) in children, to provide a reference for clinical evidence-based medicine. Methods Guidelines concerning GBS were electronically retrieved from PubMed, EMbase, CBM, Wanfang data, CNKI and Vip. The guide databases includes major medical institutions and industry sites such as NGC, GIN, TRIP , CDC, IDSA, AAP, WHO, Chinese Health and Family Planning Committee website, library of clinical guidelines China and Chinese clinical guidelines for collaboration. All the data were searched from inception of the database or network to Oct. 2013. Two reviews independently screened literature according to the inclusion and exclusion criteria, and assessed the quality of guideline using the AGREEⅡ. Intraclass correlation coefficient (ICC) was used to examine the conformance of the raters' evaluation scores. Results A total of 5 guidelines concerning GBS were included, with a time range from 2003 to 2012, and origins from USA, EU and Canada. The final recommendation levels of the 5 articles were level B. According to the AGREEⅡ, domain 3 and 4 showed the higher scores, and scores were generally low in domain 5. Plasma exchange (PE) and intravenous immuneglobulin (IVIG) showed positive effects on the treatment of GBS. But it was not recommended that combined PE and IVIG. Corticosteroids are also not recommended for GBS treatment. Conclusions The recommendations of medicines for GBS are basically consistent. However, the classification criteria of the levels of evidence and recommendation are still unconsistent and suboptimal. The guidelines on GBS should be improved in“Applicability”in future.

Objective:To explore whether the effect relieving chronic heart failure (CHF) induced by Adriamycin of Ginsenoside-Rbl (Gs-Rbl ) is related to inhibiting Toll-like receptor (TLR ) . Methods :Adriamycin-induced CHF model rats were randomly divided into Adriamycin group (n=15) and Gs-Rb1 group (70 mg/kg d ,n=17);another 10 normal rats were regard as control group .Neonate rat cardiomyocytes were also randomly divided into control group ,Adriamycin group (1 μmol/L) and Gs-Rb1 group (1 μmol/L Adriamycin + 200 μmol/L Gs-Rbl) .After the intervention being performed ,echocardiography and expressions of TLR2/TLR4 gene and protein were assessed in all groups .Results:(1) Both studies in vivo and in vitro indicated that expressions of TLR 2 protein and mRNA in Adriamycin group were significantly higher than those of control group ,compared with Adriamycin group ,there were significant reductions in expressions of TLR2 protein [ (0.975 ± 0.022/0.564 ± 0.031) vs .(0.593 ± 0.018/0.344 ± 0.024)] and mRNA [ (0.576 ± 0.029/0.853 ± 0.043) vs .(0.349 ± 0.015/0.401 ± 0.021)] in Gs-Rbl group ,P<0.01 both ;(2) No matter study in vivo or in vitro ,expressions of TLR4 protein and mRNA in Adriamy-cin group were significantly higher than those of control group ,compared with Adriamycin group ,there were signif-icant reductions in expressions of TRL4 protein [ (0.654 ± 0.032/0.519 ± 0.013 ) vs . (0.371 ± 0.013/0.254 ± 0.027)] and mRNA [ (1.602 ± 0.013/0.838 ± 0.021) vs .(1.140 ± 0.021/0.503 ± 0.022)] in Gs-Rbl group , P<0.01 both .Conclusion:Adriamycin may trigger the process of CHF through increasing TLR 2 and TLR4. The effect of Gs-Rbl improving adriamycin-induced CHF may be related to inhibition of TLR 2 and TLR4 .

Objective To investigate the effects of homocysteinemia (HHcy) and hypertension on left ventricular re?modeling. Methods A total of 275 patients with coronary heart disease were divided into four groups including H-type hy? pertension group (n=96), non-H-type hypertension group (n=44), HHcy+non-hypertension group (n=53) and control group (n=65) based on their blood pression levels and plasma HHcy levels. The serum levels of glucose (Glu), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high-density lipoprotein (HDL) were compared between groups. The left ventricular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD), left ventricular posterior wall thickness (LVPWT), ventricular septal thickness (IVST) and left ventricular mass index (LVMI) were observed in four groups. The proportion of patients with left ventricular remodeling was also compared between four groups. The influence fac?tors of left ventricular remodeling were analysed. Results There were no significant differences in biochemical parameters except Hcy level between frour groups. The values of LVMI, left ventricular wall thickness and the proportion of patients with left ventricular remodeling were significantly higher in H-type hypertension group than those of other three groups ( P<0.05). The Hcy level was positively correlated with LVMI and left ventricular wall thickness. Logistic regression analysis showed that HHcy and hypertension were the risk factors of left ventricular remodeling (OR=7.443, 7.754 and 9.948,P<0.05). The risk factors of left ventricular remodeling were higher in patients with both HHcy and hypertension than those in patients with HHcy or hypertension. Conclusion Homocysteine and higher systolic pressure are independent risk factors for left ventricular remodeling and they have a synergistic effect on leading to left ventricular remodeling.

Objective To explore modification of islet cell function in type 2 diabetes by the treatment of insulin detemir and insulin aspart.Methods A total of 68 patients with diagnosed type 2 diabetes were randomized into two grouops,the control group (insulin glargine combined with insulin aspart)and observation group (insulin detemir combined with insulin aspart),each group had 34 cases.Before and after treatment,fasting insulin and 2 h postprandial insulin,glycated hemoglobin (HbA1c),C peptide and fructosamine (FMN)levels were compared in two groups,and the treatment safety was observed.Results After treatment,fasting insulin and C -peptide levels in the two groups were significantly increased than before treatment(P <0.05 ).In observation group,2 h postprandial insulin level (29.97 ±9.18)mIU /L was significantly higher than before treatment (20.79 ±7.49)mIU /L(t =4.52,P =0.00), which was better than the control group (24.67 ±7.69)mIU /L,the difference was significant (t =2.58,P =0.01). After treatment,postprandial 2h C peptide levels in the two groups had no significant differences compared with before treatment (P >0.05).In the observation group,except for 2h postprandial insulin levels,other indicators had no significant differences compared with the control group (P >0.05 ).After treatment,FMN and HbA1c in the two groups decreased significantly compared with before treatment(P <0.05 ),but there was no significant difference between the two groups (P >0.05).During treatment,both two groups observed hypoglycemia,but there were no severe adverse reactions.Conclusion The clinical application of insulin detemir combined with insulin aspart in the treatment of type 2 diabetes can significantly improve the insulin -producing cells and accelerate functional recovery, and the clinical effect is better than the united aspart insulin glargine,with no significant adverse reactions,it can be recommended as a clinical type 2 diabetes treatment drug of choice.

Objective To investigate the changes of the expression of GDNF and GDNFR?1 of long-term denervation of posterior cricoarytenoid muscles(PCAMs).Methods 38 patients with vocal paralysis were grouped into four according to their denervated period of time while 12 normal PCAMs as control group.Using double immunofluorescence stain,changes of GDNF and GDNFR1 expression were observed in myofibers at different time points after denervation.Results Double immunofluorescence stain with antibodies against GDNF and GDNFR1 showed no staining in the control group,and study groups.However,after the muscle denervation lasted for 6-12 months and 1-2 years,noted was a significant accumulation of GDNF and GDNFR1 protein in cytolemma and endochylema of myofiber.The mean grey scales and positive region ratios were compared using the image analysis system.The results revealed the levels of GDNF and GDNFR1 protein expression in 6-12 months group,1-2yr group changed significantly(P0.05).Conclusion The changes in expression of GDNF and the acceptor GDNFR-?1,a powerful neurotrophic factor,implied that a good nervous regenerated microenvironment in PCAMs within 2 years.This experiment indicated that denervated posterior cricoarytenoid muscles are able to regain their functions through reinneration within 2 years.

Objective To investigate the clinical characteristics of sever acute pancreatitis (SAP) with high triglyceride(TG). Methods 82 patients with onset of SAP within 72 hours were involved in this study. These patients were divided into high TG group (n=26) and normal TG group (n=56) according to serum TG lev-els tested (high TG group≥1.7 mmoL/L;normal TG group<1.7 mmol/L on admission). Results 31.71% (26/82) SAP patients were discovered with high TG APACHE-Ⅱ grade of high TG group was higher than that of normal TG group on admission[(14.62±7.58) vs (10.68±5.21),P<0.01]. Within the onset of 72 hours,the incidence of cardiac,pulmonary and kidney dysfunction in high TG group was higher than those of normal TG group (34.62%,34.62% and 19.23% vs 5.36%,3.57% and 1.79%,P<0.01),and the incidence of pancreatic pseudocysts was higher in high TG group than that of normal group(42.31% vs 7.14%,P<0.01). No emergency and early-stage surgical cases in high TG group but 13 cases(23.21%) in normal group. There were 2 cases of high TG group and 4 of normal group averting to operation. Conclusion SAP patients with high TG have high incidence of early-stage organ dysfunction and local complication,in this case nonsurgical intervention is the first choice.

Objective To determine the effects of prostaglandin E_2 alone and the combination with omeprazole for poisoning related acute mucosal lesion. Methods Forty-two healthy SD rats were randomly divided into 7 groups: control group (control), methamidophos poisoning model group (intox), 10 mg/kg omeprazole group (ome1), 50 mg/kg omeprazole group (ome2), 10 μg/kg prostaglandin E_2 group (PG1), 50 μg/kg prostaglandin E_2 group (PG2), 10 μg/kg prostaglandin E_2 combined with 10 mg/ kg omeprazole group (union). The gastric ulcer index was counted and the content of serum cholinesterase, endothelin, and tumor necrosis factor were measured, and dependability was analyzed. Results There was no obvious difference between the prostaglandin group and the poisoning model group in gastric ulcer index, endothelin, and tumor necrosis factor. The omeprazole alone and the combination treatment could improve the acute gastric mucosa lesion induced by methamidophos poisoning. Conclusion Prostaglandin E_2 alone can not obviously improve the acute gastric mucosa lesion by methamidophos poisoning. The combination with omeprazole may be a promising treatment.
