Objective To investigate the characteristics of coronary's pathological changes in patients with impaired glucose tolerance. Methods Four-hundred and ninety patients who were suspected with ischemic chest pain were divided into three groups according to their OGTT results: (1) IGT group: n = 161,(2) 12DM group:n = 159, (3) NGT group: n = 170. Serum levels of triglyceride (TG) , total cholesterol (TC) , highdensity lipoprotein cholesterol (HDL-C) , low-density lipoprotein cholesterol (LDL-C) and high sensitive Creactive protein (hs-CRP) were detected, their body mass indexes (BMI) were calculated. General clinical information (including gender, age, history of smoking, history of hypertension) were collected. All the CAG results were analyzed and Gensini scores were assessed as well. Results The TG levels in the T2DM group and IGT group ([2. 41 ± 1.70] mmol/L and [2. 26 ± 1. 20] mmol/L) were significantly higher than that of the NGT group (1.95 ± 1.14) mmol/L, the differences were significant (t=0.4610,0.3124, P<0. 01 and 0.05,respectively),whereas there was no significant difference between the IGT group and T2DM group (P >0.05);No significant difference was found among the three groups about TC, HDL-C, LDL-C levels (either P > 0.05). The levels of hs-CRP in T2DM group ([2. 38 ± 1. 76] mg/L and IGT group [2. 33 ± 2. 03] mg/L) were higher compared with the NGT group ([1. 54 ± 1. 32] mg/L), the differences were significant (t = 0. 8391,0. 7815, Ps < 0. 01), whereas there was no significant difference between the IGT group and T2 DM group (P >0.05). BMIs of the IGT group ([25.50 ± 3.04]kg/m2) and T2DM group ([26.09 ± 2.86]kg/m2) were higher than that of the NGT group ([24. 70 ± 3. 27] kg/m2), the differences were significant (t = 0. 8063,1. 3947, P<0. 05 and <0.01, respectively),whereas no significant difference was found between the T2DM group and IGT group (P > 0. 05). The incidence of single coronary pathological changes was 44.7% in the NGT group,it was higher than that of the IGT group (23. 6%) and T2DM group (18. 9%) (x2 = 16. 310,25. 116,Ps < 0. 05), whereas there was no significant difference between the IGT group' and T2DM group (P > 0. 05);The incidences of 2 branches pathological changes in the T2DM group (37. 1%) and IGT group (39. 8%) were higher compared with NGT group (23. 5%) ,the differences were significant (x2 =1. 200,10. 099,Ps <0. 05),whereas there was no significant difference between the IGT group and T2DM group (P >0. 05) ;The incidences of 3 vessels pathological changes in the T2DM group (40.9%) and IGT group (33. 5%) were higher than that of the NGT group (20. 0%) , the differences were significant (x2 = 7. 767,17. 028, Ps < 0.05), there was no significant difference between the IGT group and T2DM group (P > 0. 05). The incidence of subtotal or total occlusion of the T2DM group and IGT group were 22. 6% and 18.0% respectively,both were higher than that of the NGT group(7. 6%) (x2 = 14. 573,8. 019 ,Pa < 0.05) , whereas no significant difference was found between the T2DM group and IGT group (P > 0. 05). The incidences of vascular diffusing pathological change in the IGT group (24. 8%) and T2DM group (30. 8%) were higher compared with the NGT group (12.4%) (x2 =8.583,16.724, Ps < 0.05), whereas there was no significant difference between the IGT group and T2DM group (P >0.05). The Gensini scores in the IGT group (55. 05 ± 22. 99) and T2DM group(56. 15 ± 24. 87) were significnatly higher than that of the NGT group (38. 03 ± 17. 38), the differences were significant ((t =17.0142,18. 1186,Ps <0.01),whereas there was no significant difference between the IGT group and T2DM group (P>0.05). Conclusion The incidences of 2 and 3 vessels pathological changes increase significantly in patients with IGT. Moreover, the incidences of occlusion and diffuse stenosis increase significantly. This is similar to the coronary artery pathological charactersitics in patients with diabetes, which indicates that IGT is closely related to the pathological severity of coronary artery. We should pay much attention to those patients with IGT in the clinical work.

Objective To identify the pathogens that cause hand, foot and mouth disease (HFMD) in adults and analyze the nucleotide sequences characteristics of enterovirus 71 (EV71). Methods The reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect the enterovirus from the samples of four adult HFMD patients. The 227 bp amplified segments of EVT1 were then sequenced and compared with the sequences of previously isolated EVT1 strains available from GenBank by homogeneity and phylogenetic tree analyses. Results All the results of RT-PCR with enterovirus universal primers and EVT1 specific primers were positive. The EV71 sequences analysis showed that the four new sequences (named as GZ19610, GZ99310, GZ99355 and GZ46477) shared 96.0% to 99.1% nucleotide identify themselves and shared 96.9% to 100.0% homology with the strain Fuyang/17.08/3 isolated in 2008 from Fuyang, Anhui Province. Phylogenetic tree analysis showed that the genotype of the four new sequences was all subtype C4, they were the same sub-genotype as those strains isolated from Chinese mainland and Chinese Taiwan in 2004, and the genetic distance between them was most closely. Conclusions EV71 can cause adult HFMD. Compared with the nucleotide sequences of EV71 strains that isolated now and formerly in China, there is no large variation of the EV71 sequences isolated from four adult HFMD patients in Guangzhou this time. The adult HFMD patients should be isolated for treatment to avoid them transmitting the virus and causing disease spreading.

Aim To elucidate the therapeutic effect of ginsenosides, berberine and jasminoidin after given a-lone or treatment with combination on the focal cerebral ischemia rats and study the compatibility mechanism. Methods We determined 12 endogenous amino acids in serum of rats after cerebral ischemia over 12 hours with RRLC-QQQ to evaluate the integrated role of YQJD at the dosage of 25 mg·kg-1 and 5 mg·kg-1 . Generally accepted methods were used, including be-havior test, One-Way AVONA, PLS-DA, as well as PCA to evaluate the injury induced by focal cerebral is-chemia. Results The score of neurological deficits and the level of five amino acids, namely Glu, Asp, Met, Hcy, Phe in the combination of ginsenosides, berberine and jasminoidin group in the dosage of 25 mg ·kg-1 and 5 mg·kg-1 significantly decreased (P<0. 05, P<0. 01) compared to those of model group. For another, the largest contribution group in the three principal components of PC1 , PC3 , PC4 at the dosage of 25 mg/kg and the six principal components PC1 ~PC5, PC7 in 5 mg·kg-1 was the combination of gin-senosides, berberine, jasminoidin group. Conclusions The results suggest that the efficacy of the combina-tion of ginsenosides, berberine and jasminoidin is su-perior to the combination of two or any single compo-nent, which can significantly improve the metabolic disorder of the endogenous amino acid after cerebral is-chemia. And it could be speculated that ginsenosides may play a more important role than berberine and jas-minoidin in regulating the level of amino acid metabo-lism.

Objective To detect and analyze the haemagglutinin (HA) gene of the first influenza A-H1N1 viral strain isolated in Guangdong Province during an influenza A pandemic in 2009.Methods A-H1N1 virus strain was isolated from the throat swab of the first patient diagnosed with A-H1N1 virus infection in Guangdong Province in 2009. Viral nucleonic acid was extracted from supernatant of cell culture and amplified using reverse transcriptase-polymerase chain reaction (RT-PCR) with HA gene-specific primers. The product was cloned, sequenced, and the homology was analyzed. Results A 1710 bp HA gene of the first influenza A-H1N1 viral strain in Guangdong Province in 2009 was acquired, which was named as A/GuangzhouSB/01/2009 (H1N1) HA with GenBank access No. GQ268003. The homology of the studied HA gene and the 277 influenza A (H1N1) isolates reported in the epidemic areas was 99.0%-99.8%, and as high as 99.8% when compared with the isolates reported in the United States where the patient had traveled. When the studied HA gene was compared with 25 isolates of Chinese seasonal A-H1N1 virus, the homology was 72.3%-85.6%. Conclusions The homology of the first isolated A-H1N1 viral strain in Guangdong Province in 2009 and epidemic influenza A-H1N1 virus is high, while it is low compared with Chinese seasonal A-H1N1 virus.

Objective:
To investigate the predictability on adverse events(re-hospitalization and death)in elderly discharged inpatients among frailty phenotype(FP), frail scale(FS)and clinical frailty scale(CFS), in order to screen the simple and feasible frailty assessment tools for elderly discharged inpatients.
Methods:
Elderly discharged inpatients aged 65 years and over were recruited for this prospective cohort study.And they underwent frailty assessment by using FP, FS and CFS, respectively.Patients were followed up for more than 6 months after discharge, and adverse events including re-hospitalization or death after discharge were recorded.Cox regression model was adopted to evaluate the relationship between frailty and death or re-hospitalization.Predictive effects of three assessment methods on adverse events were compared by using receiver operating characteristic(ROC).
Results:
A total of 527 elderly patients aged(84.1±6.0)years with males of 61.9%(326/527)were successfully followed up.The detection rate of frailty by FP and FS evaluation tools was 26.0%(137/527)and 26.0%(137/527), respectively.The detection rate of moderate and severe frailty by CFS was 25.2%(133/527). The Cox regression model showed that the mortality was significantly higher in frailty patients by FP, FS, and CFS than in the non-frailty patients(
