Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.

Objective To evaluate the effects of optimal pharmacotherapy according to guideline on treating chronic heart failure(CHF)in real world clinical practice. Methods A total of 231 consecutive outpatients with reduced left ventricular ejection fraction(LVEF≤40%)and enlarged left ventricular end diastolic diameter(male ＞55 mm, female ＞60 mm)were recruited from January 2001 to June 2009. All patients were treated with optimal pharmacotherapy according to guideline recommendations and followed up to December 31,2009. Mortality, rehospitalization and changes of heart size and cardiac function at baseline and at the end of follow-up period were analyzed. Results(1)14 patients were lost during follow-up (6. 1%), and follow-up was complete in 217 patients(93.9%). 97.2% and 98.2% patients were prescribed angiotensin converting enzyme(ACE)inhibitors and β-blockers(βB). Combined of ACE inhibitors and BB use was applied in 95.3% patients. The target dose of ACE inhibitors and βB were reached in 50. 7% and 37.3% patients.(2)Lower mortality and re-hospitalization rates were observed in this cohort: all-cause morality, average annual mortality was 11.5% and 3.9% respectively. Rehospitalization rate was 27.6%.(3)Left ventricular end-diastolic diameter(LVEDD)decreased from (68.2 ±7.2)mm to(62. 2 ±9. 6)mm. LVEDD value was normal or near normal(male≤60 mm, female ≤55 mm)in 43.2% patients. LVEF improved form(29. 8 ±7. 5)% to(43. 3 ± 11.8)%, LVEF was ＞40% in 60.4% patients, LVEF was ≤ 40% but increased ≥ 10% after treatment in 22.9%patients. Conclusion Optimal pharmacotherapy according to guideline can improve prognosis of outpatients with CHF.

Objective To optimize antimicrobial use process,ensure the rational use of preoperative antimicrobial prophylaxis during consecutive operations.Methods Antimicrobial use process in a hospital in December 2015 was optimized,6 072 cases of consecutive operations in May-November 2015 were selected as control group,5 832 cases of consecutive operations in December 2015-May 2016 were as trial group,the qualified rate of rational use of antimicrobial agents was compared between two groups,causes for delayed/prior use was analyzed.Results Before and after the optimization of antimicrobial use process,rates of antimicrobial use were 77.16％ and 78.80％ respectively,there was significant difference between two groups(x2 =8.305,P =0.004).After the optimization of antimicrobial use process,rate of antimicrobial use within 0.5-1 hour was significantly higher than that before the optimization (82.36％ vs 41.11％);rate of antimicrobial use ＜0.5 hour before skin incision decreased from 57.11％ before optimization to 4.32％ after optimization;but rate of antimicrobial use ＞1 hour before skin incision increased from 1.78％ to 13.32％.Causes for delay/prior use of antimicrobial agents was due to the lack of effective communication between doctors and nurses,which resulted in circuit nurses' inaccurate assessment on interval of consecutive operations(62.13％),the duration of intubation or puncture was too long for anesthesiologists (13.57％).Conclusion Optimizing antimicrobial use process in consecutive operations can improve prophylactic antimicrobial use rate within 0.5-1 hour,and is helpful for ensuring the efficacy of antimicrobial prophylaxis.

OBJECTIVEOur previous study indicated that the death receptor Fas played a key role on hepatocyte apoptosis in nutritional steatohepatitis in mice. This study aimed to explore whether Fas mutation accelerated hepatic steatosis and inflammatory infiltration in methionine-choline deficient (MCD) diet feeding mice.

METHODSMice homozygous for the lymphoproliferation spontaneous mutation (C57BL/6J-Faslpr) and wild type C57BL/6J mice were fed with MCD diet for three weeks to induce non-alcoholic steatohepatitis (NASH). Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG) and total cholesterol (TC) levels were detected by an Olympus AU5400 automatic chemical analyzer. The role of Fas gene mutation on NASH was assessed by comparing the severity of hepatic steatosis and inflammation in the liver sections, the mRNA and protein expressions of hepatic inflammatory and fibrogenesis related factors, proliferating cell nuclear antigen (PCNA) and transforming growth factor beta 1 (TGFb1).

RESULTSThe serum ALT levels of the wild type and Faslpr mice fed with MCD were significant higher than that of the control mice (126.33+/-10.50 U/L vs (25.00+/-10.14) U/L, (160.33+/-48.29) U/L vs (18.33+/-9.08) U/L, with the LSD-t value 12.02, 5.08 respectively, the P value<0.001, 0.007 respectively. The serum ALT levels showed no significant difference between the Faslpr and wild type mice fed with MCD, with the LSD-t value 1.19, the P value 0.229. The serum AST, TG and TC levels showed neithere significant difference among the four groups. MCD diet induced hepatic steatosis and inflammatory infiltration in both of the wild type and Faslpr mice. Especially, severer hepatic injury was observed in Faslpr mice as compared with wild type mice. The mRNA expression levels of cell proliferation factor PCNA and fibrogenesis growth factor TGF b1 in wild type mice fed with MCD were significantly higher than that of the control mice (2.84+/-0.73, 2.77+/-0.54 vs 1.31+/-0.18, 0.89+/-0.18), with the LSD-t value 4.99, 8.08 respectively, the P value 0.001, <0.001 respectively. The mRNA expression levels of PCNA and TGFb1 in Faslpr mice fed with MCD were significantly higher than that of the Faslpr control mice and the wild type mice fed with MCD (5.57+/-1.13, 5.73+/-0.89 vs 1.04+/-0.16, 0.85+/-0.11 and 2.84+/-0.73, 2.77+/-0.54), with the LSD-t value 10.15, 13.19 and 5.33, 6.91 respectively, the P value<0.001. The protein expressions levels of PCNA and TGFb1 were concordant with the mRNA.

CONCLUSIONSFaslpr promoted hepatic steatosis and inflammatory infiltration in mice fed with MCD diet, which might associated with excessive release of cell proliferative, inflammatory and fibrogenesis factors.

BACKGROUNDAngiotensin converting enzyme (ACE) inhibitors and β-blockers (βB) have beneficial effects on left ventricular (LV) remodeling, alleviate symptoms and reduce morbidity and mortality in patients with chronic heart failure (CHF). However the correlation between the d osages of ACE inhibitors, βB, and recovery of LV structure remains controversial. Clinical factors associated with recovery of normal ventricular structure in CHF patients receiving medical therapy are poorly defined. Here we aimed to identify variables associated with recovery of normal or near-normal structure in patients with CHF.

METHODSWe recruited 231 consecutive CHF outpatients, left ventricular ejection fraction (LVEF) ≤ 40% and left ventricular end diastolic diameter (LVEDD) > 55/50 mm (male/female), who were receiving optimal pharmacotherapy between January 2001 and June 2009, and followed them until December 31, 2009. They were divided into three groups according to LVEDD and whether they were still alive at final follow-up: group A, LVEDD ≤ 60/55 mm (male/female); group B, LVEDD > 60/55 mm (male/female); and group C, those who died before final follow-up. Apart from group C, univariate analysis was performed followed by Logistic multivariate analysis to determine the predictors of recovery of LV structure.

RESULTSA total of 217 patients completed follow-up, and median follow-up time was 35 months (range 6 - 108). Twenty-five patients died during that period; the all-cause mortality rate was 11.5%. Group A showed clinical characteristics as follows: the shortest duration of disease and shortest QRS width, the lowest N-terminal brain natriuretic peptide (NT-proBNP) at baseline, the highest dose of βB usage, the highest systolic blood pressure (SBP), diastolic blood pressure (DBP) and the lowest New York Heart Association (NYHA) classification, serum creatinine, uric acid, total bilirubin and NT-proBNP after treatment. Logistic multivariate analysis was performed according to recovery or no recovery of LV structure. Data showed that LVEF at follow-up (P = 0.013), mitral regurgitation at baseline (P = 0.020), LVEDD at baseline (P = 0.031), and βB dosage (P = 0.041) were independently associated with recovery of LV diameter.

CONCLUSIONOur study suggests that four clinical variables may predict recovery of LV structure to normal or near-normal values with optimal drug therapy alone, and may be used to discriminate between patients who should receive optimal pharmacotherapy and those who require more aggressive therapeutic interventions.

Aim To study whether there was arterial heterogeneity and association with L-type calcium channel (LCC) in different parts of arteries in re-sponse to certain vasoconstrictor. Methods The aor-ta, renal arteries and coronary arteries were dissected from rats. Arterial ring contractions induced by pheny-lephrine (Phe), 5-hydroxyl tryptamine (5-HT) or U46619 in concentration-dependent manner were meas-ured using the Multi Myograph system and the response to nifedipne was observed. Results (1) Phe had no obvious effect on the tension of coronary artery,but in-duced concentration-dependent vasoconstriction in aor-ta and renal artery,and pEC50of aorta was significantly higher than that of renal artery (P<0.05). The inhi-bition rate of nifedipine on the aortic contractile re-sponses was significantly higher than that of renal arter-y (P<0.05). (2) The contraction induced by 5-HT on aorta was not obvious, but was significant on renal artery and coronary artery. The inhibitory rate of nife-dipine on coronary artery vasoconstriction was signifi-cantly higher than that of renal artery (P <0.05). (3) U46619 could induce aorta,renal artery and coro-nary artery concentration- dependent contraction, but the Emaxof them were both higher than that of renal ar-tery (P<0.05). And the pEC50of aorta was the lar-gest (P<0.05). Nifedipine significantly inhibited the contraction of aorta, renal artery and coronary artery induced by U46619 with the greatest inhibitory rate on the coronary artery vasoconstriction and minimal inhibi-tion on aortic vasoconstriction. Conclusions The re-sponse to certain vasoconstrictor is different among aor-ta, renal artery and coronary artery in rats, and the contraction mediated by L-type calcium channel is also different.

Effect of strophanthidin (Str) on intracellular calcium concentration ([Ca2+]i) was investigated on isolated ventricular myocytes of guinea pig. Single ventricular myocytes were obtained by enzymatic dissociation technique. Fluorescent signal of [Ca2+]i was detected with confocal microscopy after incubation of cardiomycytes in Tyrode' s solution with Fluo3-AM. The result showed that Str increased [Ca2+]i in a concentration-dependent manner. The ventricular myocytes began to round-up into a contracture state once the peak level of [Ca2+]i was achieved in the presence of Str (10 micromol L(- 1)), but remained no change in the presence of Str (1 and 100 nmol L(-1)). Tetrodotoxin (TTX), nisodipine, and high concentration of extracellular Ca2+ changed the response of cardiomycytes to Str (1 and 100 nmol L(-1)) , but had no obvious effects on the action of Str (10 micromol L(-1)). The elevation of [Ca2+]i caused by Str at all of the detected concentrations was partially antagonized by rynodine (10 micromol L(-1)) or the removal of Ca2+ from Tyrode's solution. In Na+, K+ -free Tyrode' s solution, the response of cardiomycytes in [Ca2+]i elevation to Str (10 micromol L(-1)) was attenuated, while remained no change to Str (1 and 100 nmol L(-1)). TTX, nisodipine, and high concentration of extracellular Ca2+ changed the response of cardiomycytes to Str at all of the detected concentrations in Na+, K+ -free Tyrode's solution. The study suggests that the elevation of [Ca2+]i by Str at the low (nomomolar) concentrations is partially mediated by the extracellular calcium influx through Ca2+ channel or a "slip mode conductance" of TTX sensitive Na+ channel. While the effect of Str at high (micromolar) concentrations was mainly due to the inhibition of Na+, K+ -ATPase. Directly triggering the release of intracellular Ca2+ from sarcoplasmic reticulum (SR) by Str may be also involved in the mechanism of [Ca2+]i elevation.
