Objective:To explore Toll-like receptor 2 (TLR2) and TLR4 polymorphism in Han people from Hunan region and its association with coronary atherosclerotic heart disease.Methods:Sanger sequence and statistical analysis were performed to identify the polymorphism of TLR2 and TLR4 genes in 347 unrelated Hunan Han subjects,including 180 healthy people (control group) and 167 patients with coronary atherosclerotic heart disease (coronary atherosclerotic heart disease group).Results:There was no significant difference in the genotype frequency and allelic frequency for TLR2 SNP2258G＞A and TLR4 SNP896A＞G between the 2 groups (P＞0.05),while there was significant difference in the TLR4 SNP1196C＞T between the 2 groups (P＜0.05).Conclusion:TLR4 SNP 1196C ＞T polymorphism is associated with coronary atherosclerotic heart disease in Chinese Han populationin in Hunan region.

OBJECTIVETo examine the flora samples from the tongue dorsum of the atrophic glossitis group and to discuss the relationship so as to provide a thinking pattern for therapy and a clue for deeper research.

METHODSTo collect personal information on 60 cases of atrophic glossitis and 40 cases of volunteers as control. The main items include general status, oral examination, salivary flow rate, pH value and bacteria test. All data were analyzed statistically.

RESULTS1) Among the 60 cases, 75.00% were female patients. Glosso-pain, dry mouth and taste loss were the most common symptoms. 2) In regard to the pathogenic factors, the systematic diseases were often visible, i.e. gastritis, coronary disease and anemia. 3) Oral hygiene of the patients was worse than that of the control group, the saliva flow rate and pH value were lower than that of the control. 4)The statistic analysis showed that the quantity of some bacteria of tongue dorsum and their detectable rate were different between the glossitis group and the control one, between the patients with atrophic glossitis who also suffered from different systematic diseases and the control group, and between the complete type and the partial type. These bacteria included Streptococcus sanguis, Stomatococcus, Staphylococcus aureus, Saccharomyces, etc.

CONCLUSIONAtrophic glossitis is the consequence co-affected by host, circumstances of oral cavity and bacteria. The tangible relationship between atrophic glossitis and micro-ecological changes on glossal dorsum has not been confirmed yet, however, flora change on dorsum may have relations with occurrence, and development of the disease.

OBJECTIVETo understand the survival rate of adult blood-borne human immunodeficiency virus (HIV) cases in a county.

METHODSA retrospective cohort study was carried out to determine the survival from HIV infection and related factors among 78 adult HIV cases infected by blood and confirmed by the end of 2002. Kaplan-meier method was used to describe the survival distribution and Cox proportional hazard model was used to determine the factors associated with the survival time.

RESULTSThe total mortality after infection was 78.57/1000 p-y and AIDS related mortality was 72.95/1000 p-y. The median survival time was 7.40 years (95% Confidence Interval: 6.79 - 8.02). After adjustment for the clinical stage at presentation (HIV or AIDS), people who got infected at the age of 30 - 40 years or infected by the end of 1995 would proceed to death slower than the other groups.

CONCLUSIONThe survival of HIV cases infected by blood at the county level might have been underestimated and should be adjusted when HIV/AIDS was estimated and projected. Survival was associated with age when infection started so different survival functions should be used on different age groups that infection started.

OBJECTIVETo evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor.

METHODSLiterature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies.

RESULTSTotally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%).

CONCLUSIONKetoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.

Aim To investigate the effects of astragalus polysaccharide (APS) on renal TGF-β1/Smads signa-ling pathway in rats with diabetes mellitus(DM). Methods Wistar rats were randomly divided into nor-mal group,DM group,APS low dose (APS-low) group and APS high dose (APS-high) group. Rats in APS-low group and APS-high group respectively received 200 and 400 mg·kg-1·d-1APS for 8 weeks. Con-centrations of fasting blood-glucose(FBG),blood urea nitrogen and creatinine,as well as urinary kidney injury molecule-1 (KIM-1) and osteopontin (OPN) were measured. Levels of TGF-β1,Smad2,phosphorylated Smad2 (p-Smad2),Smad3,phosphorylated Smad3 (p-Smad3),Smad7,matrix metalloproteinase (MMP) 2,MMP-9,tissue inhibitor of matrix metalloproteinases (TIMP)-1 and TIMP-2 were investigated. Results Compared to control group,DM group had higher levels of FBG,blood urea nitrogen,creatinine KIM-1,OPN, TGF-β1,Smad2,p-Smad2,Smad3,p-Smad3,TIMP-1 and TIMP-2,but lower levels of Smad7,MMP-2 and MMP-9. APS significantly decreased the levels of FBG,blood urea nitrogen,creatinine KIM-1 and OPN, as well as inhibited the activity of TGF-β1/Smads sig-naling pathway. Conclusion The renoprotective effects of APS might be associated with the inhibition of TGF-β1/Smads signaling pathway.

Objective To investigate the effects of functional magnetic resonance imaging (fMRI)with acute ischemic stroke (AIS) patients,and to evaluate the relationship between brain reorganization and motor recovery.Methods Nine AIS patients and 9 healthy volunteers were assessed by fMR1 during passive finger clenching at a pace of 1 Hz.The fMRI results were analyzed using SPM2 software.Lateral indices (LIs) and activated regions were calculated,and the relationship between LI and muscle strength was examined.Results In the control group,activation was observed in the contralateral sensorimotor cortex (SMC) and the bilateral supplementary area (SMA) during the passive movement.In the AIS group,similar results were recorded dur- ing unaffected hand movement,but the ipsilateral activation areas were greater than those on the eontralateral side during movement of the affected hand.LI results confirmed that movement of the affected hand mainly elici- ted activation in the ipsilateral hemisphere.Conclusion The different fMRI manifestations of patients and nor- mal subjects reflect brain compensation,and fMRI is valuable for studying the correlation between motor function and brain reorganization.

Objective: To investigate the predictive value of CT evaluation of fatty liver for the severity of acute pancreatitis(AP). Methods: The clinical and imaging data of 325 patients with AP from January 2013 to December 2017 were retrospectively analyzed. The demographic characteristics, etiological types, AP severity classification, persistent organ failure and death were collected. According to the ratio of the CT value of the liver and spleen (CT valueratio), whether the patients had fatty liver and the severity of fatty liver were determined. The incidence of persistent organ failure and mortality in AP patients with or without fatty liver and between the different severity grades of fatty liver were compared. Univariate and multivariate Logistic regression analysis was used to assess the independent risk factors for persistent organ failure in AP. Results: Among the 325 AP patients, 86 (26.5%) patients were in line with the CT diagnostic criteria for fatty liver and 239 (73.5%) patients did not meet the CT diagnostic criteria of fatty liver. The incidence of persistent organ failure in AP patients with fatty liver (CT valueratio<1.0) was significantly higher than that without fatty liver (CT valueratio=1.0):17.4%(15/86) vs. 7.5%(18/239), P<0.05. The rate of persistent organ failure in AP patients increased proportionally with the severity grades of fatty liver [7.5% in patients without fatty liver, 7.5%(18/239) in mild (0.7P<0.05. Single factor analysis showed that sex, body mass index (BMI, ≥ 25 kg/m²), etiological type, combined fatty liver were associated with persistent organ failure in AP (P<0.05 or<0.01). Multiple factor Logistic regression analysis showed that the elderly (≥60 years old), high BMI (≥ 25 kg/m²) and combined fatty liver were independent risk factors for persistent organ failure in AP (P<0.05 or<0.01). Conclusions Assessment of fatty liver and its severity in AP patients by CT is valuable to predict the risk of persistent organ failure.

OBJECTIVETo determine the correlation between the serum level of B-natriuretic peptide (BNP) and hemodynamic variables and to evaluate the diagnostic value of BNP in patients with decompensated heart failure (HF).

METHODSBNP levels (TRIAGE BIOSITE Diagnostics, San Diego, USA) were obtained by a rapid immunofluorescence assay in 117 patients with dyspnea including cardiogenic group (75 patients) and lung disease (42 patients). Hemodynamic parameters of 53 patients [male 28, female 25, mean age (71.6 +/- 9.8) years] with HF were determined and left ventricular end-diastolic diameter (LVEDD) of all patients were measured by echocardiogram.

RESULTSPulmonary capillary wedge pressure (PCWP, mm Hg), mean pulmonary arterial pressure (MPAP, mm Hg), right atrial pressure (RAP, mm Hg) and BNP (ng/L) levels according to New York Heart Association (NYHA) class were: 16.10 +/- 3.50, 22.50 +/- 4.68, 3.11 +/- 1.90, 271.25 +/- 159.29 in NYHA class II, respectively; 21.50 +/- 4.42, 28.60 +/- 9.35, 8.95 +/- 3.86, 619.58 +/- 237.48 in NYHA class III; 29.28 +/- 8.61, 36.50 +/- 12.32, 15.27 +/- 4.96, 1519.28 +/- 618.62 in NYHA class IV (P < 0.01-0.05), respectively. PCWP, MPAP, RAP and plasma BNP levels were directly proportional to cardiac function. The plasma BNP levels had also significant positive correlations with PCWP, MPAP, RAP, (r = 0.59, 0.50, 0.32, P < 0.05-0.01). BNP level [(918.48 +/- 453.25) ng/L] of the group with LVEDD (n = 24) > or = 60 mm was much higher than that of the group with LVEDD (n = 29) < 60 mm [(298.58 +/- 167.51) ng/L]. However, the latter was significantly higher than that in pulmonary dyspnea group with a normal left and right ventricular end-diastolic diameter [(35.4 +/- 26.4) ng/L, P < 0.01]. There was a great difference of BNP between cardiogenic dyspnea group [(761.30 +/- 480.47) ng/L]and lung dyspnea group [(35.4 +/- 26.4) ng/L], P < 0.01.

CONCLUSIONSThe plasma BNP levels had significant positive correlations with PCWP, MPAP, RAP. BNP is a cardiac neurohormone secreted from cardiac ventricles as a response to ventricular volume expansion and pressure overload. Rapid testing BNP should be of help to differentiate pulmonary dyspnea from cardiac etiologies.
