Objective To analyze the predictive value of N-terminal B-type natriuretic peptide precursor(NT-proBNP) on auricular thrombosis in patients of coronary heart disease (CHD) combined with atrial fibrillation (AF).Methods The clinical data of 124 patients of CHD combined with AF were analyzed retrospectively.All patients were divided into research group (60 cases,compliance with auricular thrombosis) and control group (64 cases,non-compliance with auricular thrombosis),according to the occurrence of auricular thrombosis.The values of NT-proBNP,fasting plasma glucose (FPG),postprandial plasma glucose(2 h PG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),oxidized low density lipoprotein (ox-LDL),high sensitivity C reactive protein (hs-CRP) and left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDd) and left atrial diameter (LAD) were detected and compared between two groups.The relative factors to the occurrence of auricular thrombosis were confirmed by multivariate Logistic analysis.The best cutoff point of NT-proBNP was confirmed by the areas under the receiver operating characteristic curve (ROC).Results The values of NT-proBNP,ox-LDL,hs-CRP,LVEDd and LAD in research group were higher than those in control group [(4 312.6 ± 209.1) pmol/L vs.(3 421.6 ± 156.8) pmol/L,(4.0 ± 0.9) mmol/L vs.(3.4 ± 0.8) mmol/L,(7.4 ± 1.3)mg/L vs.(5.8 ± 1.0) mg/L,(74.3 ± 6.8) mm vs.(58.1 ± 5.5) mm,(39.6 ± 4.3) mm vs.(32.5 ± 3.8) mm],LVEF and HDL-C were lower than those in control group [(48.2 ± 3.1)％ vs.(57.3 ± 3.8)％,(0.72 ± 0.16)mmol/L vs.(1.08 ±0.27) mmol/L],and there were significant differences (P ＜0.05).There were no significant differences in the values of FPG,2 h PG and TC between two groups (P ＞ 0.05).Multivariate Logistic analysis showed that NT-proBNP and LAD were independent factors to the occurrence of auricular thrombosis (P =0.009,0.028).There was significant difference in the occurrence of auricular thrombosis between patients with NT-proBNP ＞ 4 250 pmol/L and patients with NT-proBNP≤4 250 pmol/L (P =0.028).Conclusion NT-proBNP is an independent predictor for the occurrence of auricular thrombosis to patients of CHD combined with AF.

ObjectiveTo investigate current iodine nutritional status of different groups of people in Harbin city, and to provide the basis for development of salt iodization standard and scientific iodine supplementation.MethodsThree urban districts and three surrounding counties were chosen in Harbin,2011.In each chosen urban district and county,one district office (township) was selected,and one residents committee (village) was chosen in each of the district office(township),and 30 households were selected by systematic sampling.Iodized salt,water iodine and iodine intake per capita were investigated.In each of the residents committee (village),20 adults aged 18 - 45,30 pregnant women or lactating women,and 100 school children aged 8 - 10 were selected.Urine samples were collected and urinary iodine level were tested.Salt iodine was determined by direct titration,water and urinary iodine by arsenic cerium catalytic spectrophotometry.Iodine uptake and iodine nutritional status of different populations in Harbin urban and rural areas were compared.ResultsThe edible rate of qunlified iodized salt were 93.3％(84/90) and 96.3％(156/162) in Harbin urban and rural residents,respectively,which were all greater than 90％,and the highest value of salt iodine were 38.3,46.0 mg/kg,respectively,in urban and rural areas,which all did not exceed the upper limit(50 mg/kg) of qualified iodized salt,but there were some samples of salt iodine content below the national standard(20 mg/kg).Water iodine value in urban and rural areas,even the highest value(9.40,8.40 μg/L),was failed to meet the national standard 10 μg/L; salt eaten by rural people perperson a day(8.33 g) was significantly higher than that of the urban people(7.03 g,Z=- 2.750,P ＜ 0.01); in addition to rural children aged 8 - 10,whose urinary iodine value(228.6 μg/L) was higher,the values in urban and rural adults ( 111.3,195.6 μg/L),pregnant women ( 193.0,172.9 μg/L),lactating women ( 128.4,173.7 μg/L)and urban children ( 186.8 μg/L ) were all in appropriate level.The urinary iodine medians ( 195.6,228.6 μg/L )of adults and children in rural were significantly higher than that of urban adults and children(111.3,186.8 μg/L,Z =- 2.294,- 5.434,P ＜ 0.05 or ＜ 0.01,respectively).Population composition of iodine deficiency in both urban and rural adults,lactating and pregnant women[46.7％(28/60),21.6％(13/60) ; 21.1％(19/90),21.3％ (18/89) ; 27.8％ ( 25/90 ),42.2％ (38/90) ] were significantly higher than that of the population composition with iodine excess[4.6％(4/60),5.0％(3/60) ; 16.7％(15/90),16.9％(15/89) ; 4.4％(4/90),0.0％(0/90)],but proportion of iodine excessive population in rural children [26.3％(79/300)] was significantly higher than proportion of iodine deficiency[5.6％(17/300)].ConclusionsThe natural environment of Harbin city is still in the iodinedeficient state.In addition to children in rural areas,the iodine intake and iodine nutrition level is basically appropriate; the risk of disease caused by iodine deficiency in adults,lactating and pregnant women is higher than by iodine excess,but the situation of children in rural is on the opposite.Therefore,we should strengthen the monitoring of different populations,and supplement iodine scientifically based on their need.

OBJECTIVETo investigate the status of human papillomavirus ( HPV) infection and its genotypes in male patients in Zhenjiang area.

METHODSUsing PCR and reverse dot blot hybridization, we determined the genotypes of HPV DNA in 245 male patients at our Clinic of Dermatology and STD.

RESULTSThe total rate of HPV infection was 43.67% (107/245), and 18 subtypes were detected. Among the 107 HPV-positive cases, low-risk, high-risk, and combined high- and low-risk infections accounted for 39.25% (42/107), 38.32% (41/107), and 22.43% (24/107), respectively. The most notable low-risk HPV types were HPV6 and HPV11, and the most notable high-risk HPV types were HPV16, HPV52, and HPV58. The rates of single infection and multi-infection were 53.27% (57/107) and 46.73% (50/107), respectively. One case had the most types, infected with 8 genotypes. No statistically significant differences were observed in the total rate of HPV infection among different age groups (Χ2 = 7.999, P > 0.05).

CONCLUSIONThe dominant subtypes of HPV infection in male patients in Zhenjiang area were HPV6, HPV11, and HPV16. The most common subtypes were HPV6 and HPV11 in low-risk infection, and HPV16, HPV52, and HPV58 in high-risk infection.

Hypoxia occurs in chronic and acute vascular diseases and tumor formation. The ability of tumor cells to maintain a balance between an adaptation to hypoxia and cell death is regulated by a family of transcription factors called hypoxia-inducible factor 1 (HIF-1). Tumor hypoxia mediated by HIF-1 would facilitate the likelihood of resistance to chemotherapy and radiotherapy, proliferation, metastasis and the invasive potential; all of which culminate in a decrease in patient survival. And HIF-1 alpha subunit decides the activity of HIF-1, which is regulated by oxygen. So understanding the role of HIF in signal pathway, drug resistance mechanism and its feature is crucial for developing novel anticancer therapies. In recent years, more attentions have focused on HIF-1 alpha inhibitors. It is expected that development of more potent and selective HIF inhibitors will provide an effective treatment of cancer and other HIF-related diseases. So we will focus on the biological characteristics and mechanism of HIF-1 to review currently studied HIF-1 inhibitors.

Objective: To investigate the effects of crude and prepared Polygonum multiflorum (PM) to liver injury based on idiosyncratic hepatotoxicity model co-treated with lipopolysaccharide (LPS) at a non-hepatotoxic dose, aiming to compare the difference between them. Methods: The Sprague-Dawley (SD) rats were used by ig administration, respectively with 50% alcohol extracts from crude or prepared PM alone or co-treated noninjurious dose of bacterial lipopolysaccharide (LPS, 2.8 mg/kg) via tail vein injection. Blood was collected from the inferior vena cava into a sodium citrate-anticoagulant tube, and the liver was removed. The plasma samples separated from the collected blood were used for analysis on ALT and AST activities and the isolated livers were used for histopathological assessment. Results: Both crude and prepared PM were nontoxic on normal SD rats under the dose of 17.28 g/kg, when co-treated with LPS, the liver injury was found at the dose of 1.08 g/kg of crude PM, however, 8.64 g/kg of prepared PM. Conclusion: When processed, the maximum safe therapeutic dosage of PM would be enlarged from 1.08 g/kg of crude PM that is close to clinical dosage to 8.64 g/kg of prepared PM, which is four times larger than the crude one in LPS model. It shows that toxicity of PM could be reduced by processing.

Objective:To explore the efficacy and safety of 192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with unresectable advanced obstructive extrahepatic cholangiocarcinoma. Methods:A retrospective analysis of the efficacy and safety of 18 patients with unresectable advanced malignant obstructive extrahepatic cholangiocarcinoma admitted to the Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei province from January 2014 to January 2018.All patients were pathologically confirmed and received biliary stent implantation, followed by sequential intensity-modulated radiotherapy and 192Ir three-dimensional brachytherapy.The clinical data of all patients were collected, including gender, age, clinical stage, adverse reactions, brachytherapy dose-volume parameters, changes in bilirubin levels before and after treatment, evaluation of efficacy, local control rate and survival rate. Results:All patients successfully completed the treatment.Re-examination was conducted one month after the combined treatment, of the 18 patients, 16 had partial remission (PR) and 2 were stable(SD). Among them, 14 patients had tumor shrinkage after brachytherapy compared with intensity-modulated radiotherapy, and 4 patients showed no significant change.The 6-month local control rate (LC) was 94.4% (17/18). The 1-year survival rate was 55.6% (10/18), and the 2-year survival rate was 38.9% (7/18). Statistical analysis showed that after combined treatment, total bilirubin and direct bilirubin were significantly reduced, and jaundice symptoms were significantly relieved.The adverse reactions of the patient were nausea, vomiting, fever, biliary tract infection, etc.There were no adverse reactions of grade 3 or above.Conclusions:192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with inoperable advanced extrahepatic cholangiocarcinoma has a good local control rate and tolerable adverse reactions, but the impact on long-term survival requires a large sample of controlled studies.

OBJECTIVE:To study the effects of nimesulide combined with oxaliplatin on transplanted tumor growth and im-mune function of rats with esophageal cancer. METHODS:Rats were randomly divided into model group(intragastrically given So-dium carboxymethyl cellulose solution+intravenously given 5% Glucose injection in tail),nimesulide group(intragastrically given 20 mg/kg),oxaliplatin group(intravenously given 13.6 mg/kg in tail)and combination group,10 in each group. Esophageal can-cer Eca109 cells were subcutaneously injected to develop transplanted tumor model. After modeling,rats in each group received rel-evant medicines by corresponding ways,once a day for ig,once every 4 d for iv in tail. Rats were sacrificed after 8 weeks,tumor volume and quality of rats were measured,tumor inhibition rate was calculated,and contents of tumor markers(CEA,CYFRA21-1,SCCAg),percentages of immune cells(CD3+,CD4+,CD8+T cells and NK cell)in peripheral blood were detected. RESULTS:Compared with model group,tumor volume and quality in other 3 groups were decreased (P<0.05);contents of tumor markers were decreased (P<0.05). Percentages of CD3+,CD4+ T cells and NK cell in nimesulide group were increased,percentages of CD8+T cell was decreased(P<0.05). Percentages of CD3+,CD4+T cells and NK cell in oxaliplatin group and combination group were decreased,percentages of CD8+ T cell was increased(P<0.05). Compared with nimesulide group and oxaliplatin group,tu-mor inhibition rate in combination group was increased(P<0.05);contents of tumor markers were decreased(P<0.05);percent-ages of immune cells were lower than nimesulide group and higher than oxaliplatin group(P<0.05). CONCLUSIONS:Nimesulide can enhance the oxaliplatin's antitumor effect on esophageal cancer,and decrease its inhibition degree on immune functions.
