Objective To explore the variation of serum D-lactic acid levels and the correlation between different intestinal viral and intestinal barrier function in children with hand, foot and mouth disease (HFMD). Methods The stools of 129 children with HFMD were collected and were detected by reverse transcription polymerase chain reaction. The children were divided into four groups according the fecal pathogens detection:enterovirus 71 (EV71) positive group, Coxsackie virus A16 (CoxA16) positive group, other intestinal virus positive group (EA positive group), and no intestinal virus group (EA negative group). Two ml venous blood and separation serum was collected in each group of children, and the level of serum D-lactic acid was detected further. Results There were 20 cases of other Coxsackie virus, and they were not grouped. Fifty-seven patients were in EV71 positive group, 26 patients were in CoxA16 positive group, 10 patients were in EA positive group, and 16 patients were in EA negative group. The level of D- lactic acid in four groups was 26.28 (17.02- 58.01), 14.43 (8.93- 20.66), 10.66 (6.64- 18.51) and 14.07 (11.83- 27.46) mg/L. The results of rank test showed the level of D-lactic in EV71 positive group was significantly higher than that in EA positive group (Z=-2.432, P=0.015) and EA negative group (Z=-3.092, P=0.002). Conclusions D-lactic acid level increases significantly in EV71 infection children and suggests that the illness is more serious and the intestinal barrier is damaged. Doctors should pay more attention to monitor and protect gastrointestinal function of children with HFMD.

Objective To explore the correlation between HLA-A, B alleles polymorphism and hemorrhagic fever with renal syndrome (HFRS) among Han nationality in Zunyi area. Methods Using group study, HLA-A, B genotypes were conducted in 100 HFRS cases and 100 controls among Han nationality in Zunyi area with polymerase chain reaction-sequence specific primer (PCR-SSP), gene frequency (GF) and relative risk (RR) were compared and calculated. Results The frequencies of HLA-A * 31 and HLA-B * 58 alleles in HFRS cases (GF=4%,12.5%) were strikingly higher than that in the healthy controls (X2=6.380, 7.792, P<0.05;RR=18.47,2.91). The frequencies of HLA-B * 40 alleles in HFRS cases (GF=11%) were strikingly higher than that in the healthy controls (X2=6.095,P<0.01, RR=O.47). Conclusion HLA-A * 31, B * 58 genes are positively related to HFRS of Han nationality in Zunyi area, HLA-B * 40 gene is negatively related to HFRS of Han nationality in Zunyi area.

Objective:To construct lentiviral vector which can overexpression miR-137 and produce lentivirus by lentivirus packaging system, and to explore its infection efficiency and expression in HEK293T cells.Methods: miR-137 sequence was chemically synthesized and cloned into lentiviral vector GV209, and the recombinant plasmid containing human miR-137 was obtained and identified.Then miR-137 recombinant plasmid together with two helper plasmids were transfected into HEK293T cells using Lipofectamine 2000.After the HEK293T cells were infected in multiplicity of infection(MOI) 40 for 48 h, the expression of green fluorescent protein (GFP) was observed by fluorescence microscope and the expression level of miR-137 was detected by fluorescence quantitative PCR.Results:The sequencing results showed that the inserted gene sequence was completely consistent with the published human miR-137 gene sequence in GenBank.The GFP was observed in the HEK293T cells infected with miR-137 overexpression lentivirus under fluorescence microscope.The fluorescence quantitative PCR results showed that the expression level of miR-137 in the cells infected with overexpression lentivirus was 12.74 times higher than that in the control cells.Conclusion:The lentivirus containing miR-137 gene is successful packaged, and it could efficiently infect the HEK293T cells.

Objective:To evaluate the changes of neurocognitive function in early stage in patients with first-episode schizophrenia.Methods:In this study,73 cases of patients with first-episode schizophrenia (research group) and 75 cases of health person (control group) were selected from January 2015 to January 2016 in our hospital.The neurocognitive function was evaluated by neuro-psychological testing tool and the data between two group were compared.Results:Scores of delayed recall,total recall,3 trial,2 trial and 1 trial of research group were lower than those of control group in BVMT-R test,and the difference was statistically significant (P＜0.05).In HVLT-R test,the scores of total delay,3 trial and 2 trial of research group were significantly lower than those of control group (P＜0.05).The consuming time of dominant hands and subdominant hands in pegboard tasks were significantly higher in research group than in control group (P＜0.05).Conpletion time of connection test A,color connection 1 and 2 in connection test of research group were significantly higher than those of control group (P＜0.05).Attempt number and correct number in research group in PASAT test were significantly lower than in control group (P＜0.05).Number of search errors in research group was higher than in control group,while number of search correct,search total score and digital sign score were significantly lower than in control group (P＜0.05).Total number of words,color and color / word count in research group were lower than in control group in Stroop color word test,and the difference was statistically significant (P＜0.05).WMS-Ⅲ test results between two group had no significant difference (P＞0.05).Conclusion:The neurocognitive function in early stage in patients with first-episode schizophrenia has been extensively damaged.

Objective:To investigate frequencies and polymorphism of HLA-DRB1 and DQB1 allele in the Hans of Zunyi area.Methods:Polymerase chain reaction-sequence specific primers(PCR-SSP) were used to type HLA-DRB1 and DQB1 genes of 200 unrelated healthy Han individuals in Zunyi area.Results:13 HLA-DRB1 and 7 HLA-DQB1 alleles were obtained at low resolution level in all subjects.The allele DRB1*09,DRB1*08 and DQB1*05 were showed high distributing frequencies;The allele DRB1*10 and DQB1*04 were scarcely found with low distributing frequencies.Comparied with Northern and Southern Han people,it would seem that Han people in Zunyi are more closely related to the Southern ones.The allele B*07 was scarcely found in the Southern Han with a high distributing frequency(GF=2.0%).Conclusion:HLA-DRB1 and DQB1 of Han people in Zunyi have plenty of polymorphisms.They seem to distribute in line with the Southern Han's characteristics but have their own territory feature with a high B*07 frequency.

Objective To analyze the causes,cardiac function grading and drug application related to heart failure of the patients with chronic heart failure in Yongchuan district people's hospital.Methods The cases of chronic heart failure of department of cardiology in our hospital from January 1st,2012 to December 31st,2015 were counted and retrospectively analyzed.Results 3 320 cases of chronic heart failure in our hospital chosen from 8 126 medical records accounted for 40.86% of total discharged patients in the same period,including 2 262 cases of coronary disease (68.13%),353 cases of rheumatic heart disease (10.63%)and 265 cases of pulmonary heart disease (7.98%),who took up the top three in the spectrum of disease;2 683 cases of NYHA heart function Ⅲ magnitude accounted for 80.81%;The utilization rate of diuretic,digoxin,spironolactone,angiotensin -converting enzyme inhibi-tor,angiotonin receptor blocker,beta adrenergic receptor were 71.23%,27.23%,70.48%,30.75%,30.78%respectively.The statistical analysis showed that the differences were statistically significant between the patients using diuretics and the patients using spirolactone(χ2 =2.386,P <0.001),the patients with hypertension and the patients with no hypertension using ACEI /ARB(χ2 =2.727,P <0.001),and merged chronic bronchitis patients and the chro-nic bronchitis patients using beta -blocker(χ2 =61.807,P <0.001).Conclusion The patients with chronic heart failure takes up a higher portion among the inpatients in department of cardiology in the district level hospital.The heart function decreases significantly and the normative drug therapy needs to be improved.
