Methods A total of 240 old patients of type 2 diabetes mellitus were divided into 5 groups according to the complications (non-complications, 43; cerebrovascular disease, 20; macroangiopathy, 43; peripheral neuropathy, 67; diabetic retinopathy, 67) and 5 groups according to the different nationalities (Han 90, Miao 60, Buyi 70, Shui 12, Other 8). The chemical index including serum FBG, HbAlc, TC, TG, and HDL-c of all patients were detected. The results were treated with t-test and X2 test. Results The serum levels of FBG, HbAlc, TC, TG in the diabetic patients with complications were higher than that of non-complication patients (P

Objective To establish a clinical test assay for detecting common respiratory viruses and enteroviruses (EV) by using mixed cultured Madin-Darby canine kidney cells (MDCK), human epidermoid cancer cells (Hep-2) and African green monkey kidney cells (Vero) to isolate common respiratory viruses and enteroviruses. Methods Throat swabs with influenza A and B viruses,adenovirus and EV71 were incubated with mixed cultured MDCK, Hep-2 and Vero in a single vial to observe the presence of cytopathic effects. Polymerase chain reaction (PCR), reverse transcription (RT)-PCR and monoclonal antibody-based immunofluorescene assay were also used for confirmatory test. Results The sensitive cell lines developed obvious cytopathic effects to the corresponding viruses, which were confirmed by the specific green particles observed by immunofluorescence assay and specific target PCR segments. Conclusions The shell-vial of mixed cells can simultaneously isolate different common respiratory viruses and EV. The isolated pathogens can be further confirmed by antigen test and PCR. This assay may improve the diagnosis of clinical viral diseases.

AIM To establish the quality standard for Cyclocarya paliurus (Batal.) ljinsk..METHODS The contents of water,ash and extract in twelve batches of samples were determined.TLC and HPLC were adopted in the qualitative identification and quantitative determination of quercetin and kaempferol,respectively,and phenol-sulfuric acid method was used for the polysaccharide content assessment.RESULTS The average contents of water,total ash,acid-insoluble ash,water-soluble extract and alcohol-soluble extract were 11.05％,5.81％,1.70％,11.25％ and 10.16％,respectively.The clear TLC spots demonstrated their strong specificity.Quercetin and kaempferol showed good linear relationships within the ranges of 0.004 953-0.022 29 mg/mL and 0.005 748-0.028 74 mg/mL (r =0.999 9),whose average recoveries were 97.1％ (RSD =2.59％) and 97.9％ (RSD =2.86％),respectively.Polysaccharide showed a good linear relationship within the range of 0.021 22-0.095 58 mg/mL,whose average recovery was 97.2％ (RSD =2.42％).The contents of three constituents in various batches of samples showed obvious differences.CONCLUSION In C.paliurus,the contents of water,total ash,acid-insoluble ash,water-soluble extract and ethanol-soluble extract should not be more than 13.0％,7.0％,2.0％,13.5％ and 12.0％,while those of quercetin,kaempferol and polysaccharide (calculated by dry product) should not be less than 0.040％,0.070％ and 0.60％,respectively.

Objective To investigate the characteristics and the risk factors of pulmonary function in patients with chronic obstructive pulmonary disease (COPD) for a 3 year follow-up.Methods Subjects diagnosed as COPD were followed up for 3 years in the Management Center of Chronic Respiratory Disease at XINQIAO Hospital from September 2009 to June 2012.This was a retrospective study.Parameters related to respiratory function mainly first second forced expiratory volume (FEV1),COPD assessment test (CAT),6 minutes walking distance (6MWD) and acute exacerbation were recorded during follow-up.Results Although the majority of patients were treated with drugs such as inhaled corticosteroid combined with longterm bronchial dilatation during the three years,FEV1 decreased progressively.The average annual decline of FEV1 was(31.80 ± 61.99) ml,translating into a mean annual decline of(3.74 ± 6.18) ％.However,there were significant differences in changes of FEV1.Approximately,FEV1 in 78.3％ (47/60) patients decreased,only 21.7％ (13/60) patients kept stable FEV1.There was a correlation between decrease of FEV1,FEV1 ％ predicted and the exacerbation (r =0.298,0.361,0.273;P ＜ 0.05).Logistic regression showed that the positive bronchodilator reversibility and the initial FEV1 were the independent factors associated with significant changes in FEV1 (respectively,OR =5.54,95％ CI 1.55-19.73;OR =8.28,95％ CI 1.42-48.32).Conclusion The changes of pulmonary function in patients with COPD are heterogeneous,although most patients are treated in a standard way.Nearly 80％ patients still represent deterioration of pulmonary function.Decline of FEV1 is closely related to the initial pulmonary function and bronchodilator reversibility.

Objective To evaluate shell vials of MHV,a combination of Madin-Darby canine kidney cells (MDCK),human epidermoid cancer cells (Hep-2) and African green monkey kidney cells (Vero),and conventional cell culture in detecting influenza viruses and enterovirus from fresh clinical specimens.Methods Specimens from patients with influenza-like illness and children with hand-foot-mouth disease were inoculated with both shell vials of MHV and MDCK/Vero.Then cytopathological effect (CPE) was examined daily.Influenza viruses and enteroviruses were detected by multiple reverse transcriptase-polymerase chain reaction (mRT-PCR).Results CPE of MDCK/Vero cells were stronger than the shell vials of MHV.The isolation rate of influenza virus by MHV was 24.6％ (34/138) and that by MDCK was 28.3％ (39/138),which was not significantly different (x2 =1.92,P＞0.05).That of enterovirus by MHV was 28.1％ (9/32) and that by Vero was 37.5％ (12/32),which was not significantly different (x2 =3.00.P＞0.05).Conclusions CPE in MDCK/Vero cells are easier to be observed than the shell vials of MHV.However,the shell vials of MHV are appropriate in public health emergencies,which can be used for isolation of influenza viruses and enterovirus in patients with respiratory symptoms.

Objective To test the levels of enterovirus 71 (EV71) antibody among children of different ages in Shanghai in 2011,and to investigate the relationship between antibody levels and virus infection.Methods EV71 antibody was detected by microneutralization assay from the serum specimens of healthy children of different ages collected during July to August,2011.The results were analyzed by t test for quantitative data with normal distribution,and by x2 test for count data.Results The positive rate of EV71 antibody among the 93 serum specimens was 58.1％ (54/93).The geometric mean titer (GMT) of EV71-specific neutralizing antibody was 1 ∶ 14.48.The positive rate of EV71 antibody in infants less than 6 months old was 87.5％ (21/24),and the GMT was 1∶29.56.In children aged 2 to 3 years,the positive rate of EV71 antibody decreased to 3.7％ (1/27),and GMT decreased to 1∶4.21,which were both statistically significantly lower than those less than 6 months old (x2 =36.37,t=7.58; both P＜0.01).The positive rate of EV71 antibody increased to 83.3％ (20/24) in children aged 5 to 6 years,with GMT reaching 1∶21.74.Whereas in children aged 7 to 8 years,the positive rate was 66.7％ (12/18) and GMT was 1∶20.76,without statistically significant difference compared with those aged 5 to 6 years (x2 =1.58,t=0.597; both P＞0.05).No statistically significant difference was found between boys and girls in positive rate of EV71 antibody [62.7 ％ (32/51) vs 52.4 ％ (22/42),x2 =1.02,P＞0.05] or GMT (1 ∶ 16.23 vs 1 ∶ 12.61,t=0.881,P＞0.05).Conclusions Children aged 2 to 3 years were at higher risk for EV71 infection,with EV71 antibody level significantly lower than other age groups.

Objective To understand the etiology of acute hepatitis B (AHB) in adults and investigate the mechanisms of hepatic injury and viral clearance in AHB. Methods One hundred and twenty adult AHB patients were enrolled. Epidemiological and clinical data were collected from the case history records or face-to-face inquiry, and serum samples were collected during hospitalization and follow-up. To observe dynamic patterns of AHB etiology, the markers of hepatitis B virus (HBV) were detected by enzyme-linked immunosorbent assay (ELISA); the level of HBV DNA and HBV genotype were determined by real-time polymerase chain reaction (PCR). Enumeration data were analyzed by non-parametric rank sum test. Comparison between groups was done by t test and that between rates of samples was done by Pearson χ2 test. Results Serum HBV DNA was positive in 48.33% of patients at the time of diagnosis with mean level of 9.84×04 copy/mL, and became undetectable after 12.5 days on average. The median levels of serum alanine aminotransferase (ALT) were 1600 U/L and 1490 U/L in HBV DNA positive and negative groups, respectively (z=-0. 678, P=0. 498). However, the mean levels of serum ALT were (2058±123) U/L and (1393±139) U/L in groups of HBV DNA<1×104 copy/mL and>1×104 copy/mL, respectively, which was significantly different (t=-2.17, P=0. 049). Genotype B accounted for 52.5%, genotype C 42.5 and genotype B and C mixed type 5.0% in 58 patients with HBV DNA positive. Eight patterns of serum HBV markers were presented at first visiting. HBsAg(+), HBeAg(+), anti-HBc(+), anti-HBc IgM(+) and HBsAg(+), anti-HBe(+), anti-HBc(+), anti-HBc IgM(+) were the most common patterns, which accounted for 38.3% and 30.0%, respectively. The dynamic patterns of serum HBV markers of 28 AFIB patients were prospectively followed up. The rate of serum FIBsAg loss was 100. 0% and the median time of negative-conversion was 3 weeks. The cumulative positive rate of anti-HBs was 85.7% after 52 weeks of follow-up. The rate of serum HBeAg loss was 100.0%. HBeAg was negative in 53.6% of patients at first visiting and the rest of patients achieved negative within 4 weeks after onset. The positive rate of anti-HBe was 82.1% during 52 weeks of follow-up. Total anti-HBc (including IgG and IgM) was keeping positive in all patients within 52 weeks, and the negative rate of anti-HBc IgM was 39. 3% after followed up for 52 weeks. Conclusions Rapid HBV clearance andserum HBV marker conversion are significantly different between AHB and chronic hepatitis B.
