Objective To have a knowledge of the mutagenicity of contaminates in drinking water in a certain city. Methods Mutagenic activity of organic extracts of source water chloridized water in water plant and tap water from the city were detected with single cell gel-electrophoresis mouse primary hepatocytes in culture were used and Ames test. Results For Ames test the organic extract in 3 liters chloridized water in water plant and tap water samples produced positive result and that in 6 liters source water sample still gave a negative result. For single cell gel-electrophoresis test the organic extract in 0.1 liter chloridized water in water plant tap water and 0.5 liter source water produced positive result. Conclusion The sensitivity of single cell gel-electrophoresis with primary hepatocytes in detection of genotoxicity of cloridized water and source water is much higher than Ames test.

BACKGROUNDIt is still a challenge for the cardiac surgeons to achieve adequate revascularization for diffused coronary artery disease (CAD). Coronary endarterectomy (CE) offers an alternative choice of coronary artery reconstruction and revascularization. In this study, short-term result of CE combined with coronary artery bypass graft (CABG) was discussed in the treatment for the diffused CAD.

METHODSFrom January 2012 to April 2014, 221 cases of CABG were performed by the same surgeon in our unit. Among these cases, 38 cases of CE + CABG were performed, which was about 17.2% (38/221) of the cohort. All these patients were divided into two groups: CE + CABG group (Group A) and CABG alone group (Group B). All clinical data were compared between the two groups, and postoperative complications and in-hospital mortality were analyzed. The categorical and continuous variables were analyzed by Chi-square test and Student's t-test respectively.

RESULTSDiabetes mellitus, hypertension, hyperlipidemia, and peripheral vascular disease were more common in group A. In this cohort, a total of 50 vessels were endarterectomized. Among them, CE was performed on left anterior descending artery in 11 cases, on right coronary artery in 29 cases, on diagonal artery in 3 cases, on intermediate artery in 2 cases, on obtuse marginal artery in 5 cases. There was no hospital mortality in both groups. The intro-aortic balloon pump was required in 3 cases in Group A (3/38), which was more often than that in Group B (3/183). At the time of follow-up, coronary computed tomography angiogram showed all the grafts with CE were patent (50/50). There is no cardio-related mortality in both groups. All these patients were free from coronary re-intervention.

CONCLUSIONSCoronary endarterectomy + CABG can offer satisfactory result for patients with diffused CAD in a short-term after the operation.

Objective To assess the efficacy of two antibiotic prophylactic regimens in a prospective randomized trial in 1 year for patients undergoing insertion of catheters,and to provide the evidence for uniform consensus existing on the timing,route,and choice of antibiotic.Methods During a period of 12 months,78 patients,who consecutively entered the peritoneal dialysis programme,[45 women and 33 men,mean age (48.2?15.7)years] were included.The prophylactic regimens were a single dose of ceftriaxone (1.0 g) given intravenously 30 minutes before surgery (Group A) and given cefazolin (0.25 g/L) i.p.in the each dialysis bag for 3 days postoperatively (Group B).All operations were performed in one room.The wound was observed every day,and body temperature,Count of white blood corpuscle and type,dialysate were examined every day. Results In Group A and B,none of the patients showed peritonitis or wound infection during the post-operative period (within 10 days).One of 39 patients(2.5%) in the group A,and 2 of 39 patients (5.1%) in the group B had exit site infection (P＞0.05).Conclusions There is no significant difference in the incidence of peritonitis and wound infection between two groups. Prophylactic preoperative single-dose antibiotics intravenously do as well as antibiotics given intraperitoneally for peritoneal dialysis catheter insertion,but is much more convenient.

OBJECTIVE: To compare peripheral T lymphocyte apoptosis of chronic bronchitis during an acute episode with that during a stable period. METHODS: Seventeen Chronic Btonchitis patients who presented to the ER with an acute episode were compared with 10 stable Chronic Bronchitis patients seen in the out-patient clinic. Peripheral venous blood was obtained from each patient and T lymphocytes were separated by fluorescent monoclonal antibodies. CD3, CD95 and CD25 were measured by flow cytometry. RESULTS: In the acute episode patients, the total quantity of T lymphocytes with CD3 was (42.63 +/-16.37) and with CD95 (14.15 +/-11.06). In the stable group T lymphocyte CD3 was (64.22 +/-23.90) and CD95 (34.88 +/-8.92) (t=-4.238, P <0.001; t=-8.796, P <0.001). The total quantity of Lymphocyte CD25 did not differ significantly between the two groups (P > 0.05). Total quantity of active T lymphocytes with CD3/CD25 was lower in the acute episode group (6.26 +/-3.94) compared to the stable group (10.52 +/-3143) (t=-1.068, P <0.05). CONCLUSION: T lymphocyte apoptosis increased in Chronic Bronchitis patients who presented with an acute episode. They also experienced a significant disturbance in immune function.

OBJECTIVEExplore the relationship between the HLA-G 14bp insertion/deletion polymorphism and the infection of Enterovirus 71 (EV71) for children.

METHODSWe genotyped HLA-G 14bp insertion/deletion polymorphism of 125 severe HFMD children infected with EV71 and 133 normal controls by PCR-PAGE;detected the plasma sHLA-G level of 66 heavy type and 15 critical type and 133 normal controls by ELISA.

RESULTSFrequencies of the genotype 14 bp - / - ,14 bp + / - and 14 bp + / + were 49.6% , 42.4% and 8.0% for the severe HFMD children infected with EV71, and 34.6%, 48.9% and 16.5% for the normal controls, respectively. A significant difference was observed for the frequencies of the HLA-G 14bp genotype between the two groups(chi2 = 7.850, P = 0.020). And for the allele frequencies. The plasma sHLA-G levels in heavy type were dramatically higher than that in normal controls (Z = -9.692, P = 0.000). The plasma sHLA-G levels in children with critical HFMD were dramatically higher than that with heavy type (Z = -2.420, P = 0.016).

CONCLUSIONThere was a relationship between the HLA-G 14 bp insertion/deletion polymorphism and the susceptibility to the severe HFMD children infected with EV71 and the plasma sHLA-G might be considered as a index for auxiliary diagnosis the severe HFMD infected with EV71.
