Objective To understand the epidemiological characteristics of bacillary dysentery and etiological characteristics of Shigella in Tianjin, and to provide evidence for the prevention and control measures. Methods The data of disease surveillance information reporting system from 2008 to 2014 were analyzed retrospectively. A total of 3955 stool samples came from the clinically diagnosed cases of bacillary dysentery were collected, according to the extraction method of stratified sampling in Tianjin city, suburban area, Binhai New Area and suburban area sentinel hospitals, and according to the sampling interval for the May to October from 2008 to 2014. Samples were detected and cultured for Shigella flora. Results (1) Epidemiological characteristics:from 2008 to 2014, a total of 65179 cases of bacillary dysentery were reported in Tianjin city, with an average annual incidence of 72.00/100 thousand. The annual incidence rate showed a downward trend year by year. The incidence was a downward trend, including urban (120.28/100 thousand), suburban areas (70.36/100 thousand), Binhai New Area (64.22/100 thousand) and the outer suburbs (19.39/100 thousand). The onset time was mainly concentrated in June-September, and the peak incidence occurred in August. The incidence rate was higher in people below 5 years old and above the age of 85. The annual incidence rate was higher in male patients of 0 to 24 years old and above 75 years old than that of female. The annual incidence rate was higher in female patients of 50 to 74 years old age group than that of male (P<0.05). The distribution of occupation was scattered among children and retirees. (2) Distribution of bacteria:the 229 Shigella strains were positive (5.79%), including 136 strains of Shigella sonnei (59.39%), 93 strains of Shigella flexneri (40.61%). The 89 strains of Shigella flexneri (4 strains were not detected) were detected in 8 subtypes, F2a (49.44%), F2b (22.47%) and FX (13.48%). The subtypes of Shigella flexneri were detected decreased year by year from 2008 to 2014, showing a single subtype. The highest detection rate of Shigella was found in 10-19 years old (9.55%). The S.sonnei positive rate was the highest in urban (5.09%), and the Shigella flexneri positive rate was the highest in suburban areas (3.09%). Conclusion The key population for the prevention and control of bacillary dysentery in Tianjin is scattered children and old people. It is necessary to strengthen the propaganda and health education to improve the health consciousness of the key population and their daily nursing staff. With the continuous changes of Shigella flora, it is necessary to carry out long-term monitoring to find out the regularity of shigella.

Objective To study the correlation between human leukocyte antigen (HLA)-DRB1 alleles and anti neutrophil cytoplasmatic antibodies (ANCA) in Han and Uygur ulcerative colitis (UC)patients in Xinjiang region.Methods The serum ANCA was determined by indirect immunofluorescence assay in 62 Uygur UC patients,58 Han UC patients,188 Uygur and 184 Han healthy control individuals.HLA-DRB1 typing was performed by polymerase chain reaction-sequence based typing (PCR-SBT).The allele frequency of HLA-DRB1 was compared in ANCA positive and negative Han and Uygur patients as well as healthy controls.Stratified analysis was performed according to UC clinical type,severity and involvement.SPSS 17.0 software was applied for x2 test.Once P＜0.05,the odds ratio (OR) and 95％ confidence intervals (95％CI) was calculated.Results The positive rate of ANCA in Uygur UC patients (53.2％,33/62) was significantly higher than that of Han patients (34.5％,20/58) and the difference was statistically significant (x2=4.269,P =0.045).In Uygur,the gene frequency of HLA-DRB1 * 13 in ANCA positive UC patients (0.202)was significantly higher than that of ANCA negative patients (0.017) (x2 =10.092,P=0.016,OR=16.000,95％CI:2.892 to 88.524) and healthy controls (0.075) (x2=9.351,P＝0.040,OR=3.407,95％CI:1.666 to 6.971).The gene frequency of HLA-DRB1 * 13 in ANCA positive pancolitis type UC patients (9/15) was significantly higher than that of ANCA negative pancolitis type UC patients (1/14) and the difference was statistically significant (x2=8.955,P =0.040,OR =19.500,95％CI:2.787 to 136.461).However,in Han patients,there were no significant differences of HLA-DRB1 alleles frequencies among ANCA positive patients,ANCA negative patients and healthy controls (all P＞0.05),and the results of stratified analysis were same.Conclusions In Uygur UC patients of Xinjiang region,HLA-DRB1 * 13 may correlated with ANCA and with ANCA of pancolitis type UC patients.There is no such correlation in Han patients of Xinjiang region.

ObjectiveTo investigate the correlation between benign prostate hyperplasia (BPH) and atherosclerosis (AS).Methods 95 cases were divided into two groups based on prostate volume (PV):24 cases with non-BPH (PV≤20 ml) and 71 cases with BPH (PV＞20 ml).Carotid intinal medial thickness (IMT) was determined by high resolution color Doppler sonography.ResultsLevels of triglyeeride (TG),hypersensitive C reactive protein (hs-CRP),ln fasting insulin [ln (FINS)],ln insulin resistance index [ln (HO)MA-IR)] and IMT in BPH group were significantly higher than in non-BPHgroup.The morbidity rate of coronary heart disease and cerebral arteriosclerosis in the BPH group enhanced as compared with non-BPH group.PV were positively correlated with ln(FINS),ln(HOMA-IR),TG and high density lipoprotein (HDL-C).Conclusions BPH is closely correlated with AS and their co-pathogenesis might be insulin resistance,inflammatory reaction and endothelial dysfunction.

Objective To investigate the relation of peripheral leukocyte total and its differential counts with urinary albumin(UAlb)in patients with type 2 diabetes.Methods The 564 subjects with type 2 diabetes were stratified according to UAER levels.The total and differential leukocyte counts of peripheral blood were measured.Demographic and potential metabolic confounding factors were analyzed with multiple correlation and logistic regressions to evaluate the effects of leukocyte counts on UAER.Results With the increase of UAER,the peripheral total leukocyte,neutrophil,monocyte,eosinophil and basophil counts increased.In contrast,the lymphocyte count decreased.The differences persisted even after adjusting the influence of age,sex,duration of diabetes and other known risk factors.Conclusions Our study shows that peripheral leukocyte counts,even within the normal range,are related with UAlb in subjects with type 2 diabetes in a dose-dependent manner.

Objective To compare the levels of serum high sensitivity C-reactive protein(hsC-RP) among subjects with normal fasting glucose plus normal glucose tolerance(NFG/NGT),IFG,IGT and IFG plus IGT,and to analyze the related risk factors. Methods 443 nondiabetic subjects aged 39-65 years were seperated into four groups:NFG plus NGT,IFG,IGT and IFG plus IGT.The serum hsC-RP levels and related factors were analyzed. Results Compared with IFG subjects,IGT subjects had higher hsC-RP levels.No differences in hsC-RP levels were found between NFG plus NGT group and IFG group, as well as between IGT group and IFG plus IGT group.Stepwise multiple regression showed that BMI and HOMA-IR were independent predictors of hsC-RP. Conclusions IGT subjects have significantly higher serum hsC-RP level than IFG subjetcts. The serum level of hsC-RP is associated with insulin resistance and the components numbers of metabolic syndrome.

Early growth response gene-1 is an immediate early response gene,a transcription factor which includ three zinc finger-like domains.Recentl studies demonstrate that early growth response gene-1 is involved in regulating cell cycle,proliferation and differentiation,and plays a critical role in injuring and repairing.Early growth response gene- 1 induces Target genes,and promotes extracellular environmental signal( such as oxygen deficit,oxidative stress,mechanical injury and cytokine)link with the complex biological responses.Intensive study to early growth respnse gene-1 will contribute to further illustrate the mechanism of the ischemia-reperfusion injury.This article summarizes from protein structure,signal transduction,biological functions and the relationship with ischemia- reperfusion injury.

To investigate the correlation between traditional Chinese medicine (TCM) syndrome and short-term prognosis of ischemic stroke.

Objective To study the changes in and correlations between the partial pressure of end-tidal carbon dioxide (PETCO2) and the coronary perfusion pressure during cardio-pulmonary resuscitation (CPR) based on the cardiac arrest dog models of ventricular fibrillation by electric shock. Methods 36 healthy dogs were evenly randomized into 3 groups including 4 minutes close-chest CPR(CCCPR) group, 4 minutes open-chest CPR(OCCPR) group, and 8 minutes OCCPR group. There were 12 dogs in each group, half male and half female. In the process of CPR, all parameters about PETCO2 and CPP were recorded. Results In the 4 minutes CCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.992 (P<0.05), which was in positive linear correlation. In the 4 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.937 (P < 0.05), which also showed positive linear correlation. In the 8 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.952 (P<0.05), and was also in positive linear correlation. The percentage of ROSC was 66.7(8/12) in the 4 minutes CCOPR group, 100%(12/12) in the 4 minutes OCCPR group and 58.3%(7/12) in the 8 minutes OCCPR group. There were statistical differences in CPP, PETCO2 between models with ROSC and without ROSC at 1, 2, 5, 10, 15 and 20 mins of CPR (all P<0.05). Conclusions This research shows that there is a close positive linear relationship between the coronary perfusion pressure and the PETCO2, and PETCO2 could be used to evaluate the prognosis of the CPR.
