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 effect of gravity and lung volume on MR perfusion imaging of human lung using an arterial spin labeling sequence called flow sensitive alternating inversion recovery(FAIR).MethodsMagnetic resonance imaging of lung perfusion was performed in supine position in ten healthy volunteers on a 1.5 T whole body scanner(GE medical system).Five sequentially coronal slices with the gap of 3cm from dorsal to ventral(labeled as P3,P6,P9,P12,P15,respeectivly)were obtained on end respiration and the relative pulmonary blood flow(rPBF)was measured.Another coronal perfusion-weighted image of P3 slice was obtained on end inspiration.Tagging efficiency of pulmonary parenchyma with IR(⊿SI%),the rPBF and area of the P3 slice were analyzed.respectively.Paired Student's t test was used for statistical analysis.Results(1)In the direction of gravity,an increase in rPBF of the gravity-dependent lung was found.rPBF of right lung from dorsal to ventral were 100.57±18.22,79.57±12.36,61.65±11.15,48.92±9.96,41.20±9.88,respectively；and that of left lung were 106.61±26.99,78.89±11.98,64.00±13.64,51.27±8.95,43.04±12.18.No statistical differences between P12 and P15,there were significant statistic differences of any other two coronal planes.But along an isogravitational plane,no statistical difference was observed.Regression coefficients of right and left lung were -4.98 and -5.16,respectively.This means the rPBF of right lung falls by 4.98 for each centimeter above the dorsal and that of left lung falls by 5.16.(2)For(⊿)SI%,rPBF and area,there were significant statistic differences at different respiratory phases(P＜0.05).(⊿)SI%,rPBF,area at expiration phase vs.inspiration phase were 1.12±0.31 vs 0.71±0.18,90.78±17.35 vs 52.85±8.75,(12.59±3.23)×103mm2 vs (17.77±4.24)×103mm2 for right lung;and 1.01±0.24 vs 0.70±0.11,91.08±18.68 vs 54.58±10.70,(12.34±3.08)×103mm2 vs(17.34±4.98)×103mm2 for left lung.Greater (⊿)SI%and increased perfusion were observed on end expiration than on end inspiration.The area was larger on end inspiration than on end expiration.ConclusionsThe FAIR is sensitive to perfusion changes in the gravity-dependent lung.Pulmonary blood flow is less in a state of high lung inflation than in a low state(inspiration vs.expiration).Positioning the patient so that the area of interest is down-gravity and breath-hold on end expiration may improve visibility of perfusion defects.

Objective To investigate the effect of nalmefene on sufentanil and propofol anesthesia for abortion and its impact on BIS. Methods One hundred and twenty patients undergoing abortion patients were randomly divided into group A, B, C, and D (n = 30 each). Patients in group A and B received 0.2 μg/kg or 0.3 μg/kg sufentanil, respectively, followed with 1.5 mg/kg propofol for induction of anesthesia post-pretreatment with 0.2 μg/kg nalmefene. Patients in group C and D received induction of anesthesia as patients in group A and B. According to the BIS and fluctuation of hemodynamic , the amount of propofol was adjusted. If necessary, additional single intravenous injection of 0.5 mg/kg propofol. The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2) and respiratory rate (RR) in patient before injection (T1), the eyelash reflex (T2), dilatation (T3), curettage (T4) and surgery awake (T5) were detected. The additional amount of propofol , operation time , recovery time of surgery , the steward score of orientation recovery after 1min of surgery , body movement reaction , cough , respiratory depression , postoperative visual analog digital score (VAS) 15 min later were also recorded in each group. Results Compared with group A, propofol could reduce the intraoperative body movement reaction rate , with lower postoperative VAS in group B and group D (P <0.05, respectively), with no significant difference between group C and group A (P > 0.05). The rapid recovery, surgery within 1 min orientation recovery were higher in group B, C, D compared with group A (P <0.05). However, orientation recovery score in group D was higher than that in group B (P < 0.05); The respiratory depression and choking were higher in group A and B than those in group C , D (P < 0.05, respectively). Conclusion The doses of 0.2 μg/kg nalmefene can effectively antagonize the respiratory depression , delay recovery and other adverse reactions in painless which induced by sufentanil , and the dose of nalmefene in this study failed to enhance the effect of analgesic and change the BIS values.
