Objective To investigate the change of high sensitivity c-reaction protein( hs-CRP)on carotid artery plaque. Methods A total of 5 852 individuals were selected as our subjects who randomly stratified from the health examination survey participants in Tangshan Kailuan Company community during 2006 - 2007. A total of 5 440 people(age above 40 years old,free of stroke,transient ischemic attack(TIA)and myocardial infarction ) were qualified and enrolled in the final analysis. A questionnaire survey,blood biochemical analysis and carotid artery ultrasound examination were finished by trained medical staff. According to the hs-CRP 3 mg measurements at the first and third times health examinations,all subjects were divided into four groups,including continued decreasing group(hs-CRP < 3 mg/ L),decreasing group(hs-CRP decreased from≥3 mg/ L to < 3 mg/ L ),increasing group((hs-CRP increased from < 3 mg/ L to≥3 mg/ L)and continued high group((hs-CRP ≥3 mg/ L). Multiple logistic regression analysis was used to test the impact of change of hs-CRP on carotid artery plaque. Results Incidence of carotid artery plaques in continued decreasing, decreasing,increasing and continued high groups were 33. 6%(1 308 / 3 577),44. 7%(178 / 398),45. 1%(186 / 412)and 54. 9%(151 / 275),respectively. The dependent variable was named based on carotid artery plaque(1 = plaque and 0 = no plaque),and in dependent variable was named based on hs-CRP value change (0 = continued decreasing group;1 = decreasing group;2 = increasing group;3 = continued high group). Multiply factors logistic regression analysis showed that the risk of carotid artery plaques for women increased compared to decreasing group( RR = 1. 17,95% CI:1. 01 - 1. 35,P = 0. 035). After adjusting gender,age,smoking,low density lipoprotein cholesterol,fasting blood-glucose,baseline lg( hs-CRP)and body mass index,the risks of developing carotid artery plague in increasing group and continued high group were increased compared to decreasing group among the women and whole population(for all subject:RR = 1. 33,95% CI:1. 04 - 1. 70,P =0. 023;for women subject:RR = 1. 63,95% CI:1. 08 - 2. 46,P = 0. 021). Conclusion Increasing hs-CRP is a risk factors of incidence of carotid artery plaque possibly.

Purpose:To evaluate the acute side effects an d efficacy of three-dimensional conformal radiotherapy(3-DCRT)combined with hype rthermia for locally advanced non-small-cell lung cancer(LANSCLC). Methods:From Jan.2001 to April.2003,35 patients with LANSCLC we re treated with three-dimensional conformal radiotherapy(3-DCRT) combined with hyperthermia. Results:The overall response rate(CR+PR)was 91.4%for the primar y tumor. Acute radiation esophagistis occurred in 48.6%of patients(Grades Ⅰ,Ⅱ ). Acute radiation pneumonitis was observed in 8.6% of patients (Grades Ⅰ,Ⅱ). Grade Ⅰ-Ⅱ bone marrow suppression occurred in 8.6%(3/35)of patients and Grade Ⅰ-Ⅱ myocardical injury was present in 14.3%(5/35) of patients. The median fo llow-up duration was 24(6-28) months. Conclusions:Hyperthermia combined with 3-DCRT is well tolerate d in most patients with LANSCLC. Its early responses are milder than the convent ional radiotherapy. Remote results await futher follow-up.

Objective To analyse risk factors for bile leakage after liver resection.Methods Between January 2011 and December 2012,469 patients underwent elective hepatectomy.We prospectively collected and retrospectively analyzed demographic data,pathological variables,and perioperative variables.Univariate analysis screened the related factors of bile leakage after liver resection.Multivariate analysis identified the independent risk factors of postoperative bile leakage.Results 469 patients were included in the analysis.The prevalence of bile leakage was 22.6％ (n =106).Univariate analysis identified the following risk factors as male gender,portal hypertension,steatosis,cirrhosis,ChildPugh grade,ascites,operative time,intraoperative transfusion,intraoperative blood loss,portal triad clamping,microwave solidification,lymphadenectomy,number of tumor,tumor margin,tumor capsular,diameter of tumor,portal vein invasion or portal branch thrombosis,number of abdominal drains.Multivariate analysis identified 4 independent risk factors for postoperative bile leakage:Cirrhosis [OR =13.2 (2.3,76.9),P =0.004],steatosis [OR =73.1 (17.7,301.5),P ＜ 0.001],infusion volume of the surgery day [OR=1.0 (1.0,1.0),P=0.019] and diameter of tumor [OR=1.2 (1.1,1.3),P=0.003].Conclusions Cirrhosis,steatosis,transfusion volume of the surgery day,and tumor size were risk factors for bile leakage after major liver resection.

Objective To investigate the relationship between arsenic in drinking water and skin lesions in endemic arsenism area in Shanyin County of Shanxi Province,in order to provide epidemiologic data for further arsenism research.Methods One hundred and eighty-nine endemic arsenism patients and 59 controls were randomly selected in 17 endemic amenism countries in Shanyin County of Shanxi Province.The content of arsenic in drinking water which wa8 collected indoom was half-quantitatively screened by a kit made by Chinese Center for Disease Control and Prevention,then quantitatively determined by HPLC-ICP-MS.Patients of endemic arsenism were diagnosed by "The Standard of Diagnosis for Endemic Amenism"(WS/T 211-2001).Results There were 64.9% (87/134)samples above the arsenic level(50μg/L)of drinking water and the median value of arsenic in drinking water was 91.43 μg/L in 134 water samples.The OR(95%CI)value between arsenic in drinking water and hyperkeratosis,hyperpigmentation,depigmentation was 2.46(1.22-4.94),3.34(1.50～7.44)and 2.86(1.50-5.46),respectively.The prevalence of hyperkeratosis,hyperpigmentation and depigmentation increased,as the arsenic in drinking water increased(≤10,≤50,≤200,＞200μg/L),especially in＞200μg/L group(OR=6.15,13.96,11.41,P＜0.05).The arsenic level in drinking water of Ⅲ degree of depigmentation patients(318.300μg/L)was higher(P＜0.05)than that of 0,Ⅰ and Ⅱ degree groups(86.670,131.800,1 10.590μg/L,P＜0.05).Conclusions Shanyin County is a medial arsenic pollution area. Arsenic in drinking water is considered as a risk factor of skin lesion. The degree of skin lesions increased,as the arsenic in drinking water increased.

Objective To explore the possible association of single nucleotide polymorphism (SNP) rs3738435 of muscarinic acetylcholine receptor subtype M3 gene (cholinergic receptor, muscarinic 3, CHRM3) with risk of type 2 diabetes mellitus (DM) and metabolic disturbance. Methods The genotypes of T-149C variant of CHRM3 gene were determined by PCR-RFLP in 573 Chinese individuals in Shanghai, including 220 newly-diagnosed type 2 DM patients without taking any drug and 353 subjects with normal glucose tolerance (NGT). In the subjects, height and weight were measured for body mass index(BMI), waist, hip and femoral circumstances for waist-to-hip ratio (WHR) and waist-to-femur ratio (WFR), and serum lipid level including total cholesterol, triglyceride, high-density and low-density lipoprotein cholesterol, blood pressure, plasma glucose levels both at 0 and 120 minute during oral 75 g glucose tolerance test (OGTT) were also determined. Results (1) There was no statistical difference in the gene frequency between groups of type 2 DM and NGT. (2) In the group of type 2 DM, significant differences were observed between TT genotype carriers and TC+CC genotypes carriers for BMI, with an obvious increase in TY genotype carriers [(26.99±3.59vs25.34±3.48)kg/m2, P=0.001]. (3) In the subgroup of type 2 DM with BMI≥25 kg/m2, total cholesterol was higher in TT genotypes than in TC+CC genotypes[(5.75±1.26vs5.27±1.14)mmol/L, P=0.030], so was the low-density lipoprotein cholesterol. Conclusion The genetic variation T-149C in the CHRM3 gene seems to attribute to weight regulation and lipid metabolism of patients with type 2 diabetes mellitus in Chinese population.

To establish a LC-MS/MS method for quantification of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid in rats plasma and study its pharmacokinetics after administration of Mailuoning injection at a single dose to rats. Plasma samples were acidified with hydrochloric acid and extracted with ethyl acetate. The analytes were determined by LC-MS-MS using a ZOBAX SB C18 column with a mobile phase of methanol-water (containing 2 mmol x L(-1) ammonium acetic) (60:40)at a flow rate of 0.5 mL x min(-1) and detected using ESI with negative ionization mode. Ions monitored in the multiple reaction monitoring (MRM) mode were m/z 353.1/191.0 [M-H]- for chlorogenic acid, m/z 178.9/134.9 [M-H]- for caffeic acid, m/z 515.2/353.0 [M-H]-for 3,4-DCQA, m/z 193.0/133.9 [M-H]-for ferulic acid, m/z 146.9/102.9 [M-H]- for cinnamic acid and m/z 246.0/125.8 [M-H]- for tinidazole (IS). After administration of Mailuoning injection at a single dose to eight Sprague-Dawley rats, the concentrations of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid in plasma were determined by LC-MS/MS method. The main pharmacokinetics parameters of measured data were caluculated by using DASver 1.0 software. The linear concentration ranges of the calibration curves for chlorogenic acid, caffeic acid, 3,4-DCQA and cinnamic acid were 2.006-1,027 microg x L(-1) (r = 0.999 6), 1.953-1,000 microg x L(-1) (r = 0.999 7), 28.51-1.459 x 10(4) microg x L(-1) (r = 0.998 9), 1.836-940.0, g x L(-1) (r = 0.997 7) and 4.780-2,447 microg x L(-1) (r = 0.998 6) respectively. The inner and inter-days relative standard deviations were both less than 5.0%, indicating legitimate precise and accuracy to the requirement of biological sample analysis. For chlorogenic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (49.78 +/- 12.81) min, (123.55 +/- 14.82) mg x min x L(-1) and (0.004 3 +/- 0.000 5) L x min(-1), respectively. For caffeic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (36.65 +/- 10.59) min, (91.67 +/- 11.77) mg x min L(-1) and (0.005 7 +/- 0.000 7) L x min(-1), respectively. For 3,4-DCQA, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (50.08 +/- 13.78) min, (278.34 +/- 31.82) mg x min x L-1 and (0.001 6 +/- 0.000 2) L x min(-1), respectively. For ferulic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (51.39 +/- 15.52) min, (34.72 +/- 4.67) mg x min x L(-1) and (0.000 4 +/- 0.0001) L x min(-1), respectively. For cinnamic acid, the pharmacokinetic parameter t1/2, AUCo-t, and CL were (74.42 +/- 18.32) min, (34.63 +/- 4.82) mg x min x L(-1) and (0.007 7 +/- 0.001 1) L x min-', respectively. The assay method is proved to be sensitive, accurate and convenient. It can be applied to the pharmacokinetic study of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid.

By retrieving the clinical research literature of treatment functional dyspepsia by traditional Chinese medicine (TCM) from January 2004 to December 2014 based on China National Knowledge Internet (CNKI), we would establish a TCM decoction database for treating functional dyspepsia in this study. One hundred and sixty-four literature were included, involving 159 prescriptions, 377 medicines, in a total of 1 990 herbs. These herbs can be divided into 18 categories according to the effectiveness; and qi-regulating herbs, blood circulation herbs, and antipyretic herbs ranked top three ones according to the frequency of usage of the herbs, whose medicine usage frequency accounted for 51.81%. Usage frequency of 16 herbs was over 30, and Atractylodes, Radix, Poriaranked top three according to the usage frequency. Medicinal properties were divided into 9 kinds according to the frequency statistics, and the top three were warm, flat, and cold. Taste frequency statistics were classifiedinto 9 kinds, and the top three were acrid, sweet, and bitter. In frequency statistics of the meridian tropism of herbs, it was classifiedinto 11 kinds, and the top three were spleen, stomach, lung. The analysis can provide a reference for treatment and study of TCM of functional dyspepsia.
