Objective To investigate knowledge of cervical cancer,human papillomavirus (HPV) and HPV vaccine and attitude to HPV vaccine among employed urban women in China,and to assess willingness to vaccinate their children.Methods This study was conducted in women from 16 factories or companies in Beijing,Hangzhou,Changsha,Chcngdu and Guangzhou.A questionnaire on cervical cancer,HPV knowledge and HPV vaccine acceptability was administered to participants before and after educational intervention.Results A total of 1 146 women were surveyed from August to November,2011.The awareness rates of cervical cancer,HPV and HPV vaccine were 95.06 ％,27.98 ％ and 12.82 ％,respectively.Only 20.68 ％ knew that HPV was related to cervical cancer.After educatioual instruction,89.26 ％ understood the relationship between HPV and cervical cancer (x2 =93.414,P ＜ 0.001).Only 19.25 ％ women were unwilling to allow their children to be vaccinated.The main reasons were as follows:worried about vaccine safety (23.52 ％),belief that their child was not at risk (21.92 ％),lack of scientific evidence for the vaccine (13.01％),and worricd about vaccine efficacy (12.79 ％).Conclusions In general,there is a high acceptability of HPV vaccine to prevent cervical cancer among employed urban Chinese women after educational intervention.However,some women remain reluctant to vaccinate their children due to concern about vaccine safety and efficacy.

Objective: To study the energy metabolism on adults with abnormal body weight. Method: Twenty four men aged 20-30 years old were chosen as the subjects whose BMI were more than 25 in obesity group, less than 18.5 in lean group and from 18.5 to 23 in normal group. K4b2 expiry monitor was used to study the energy metabolism of the subjects. Results: The total food intakes, the total energy intakes and the basal metabolism expenditure of the obese subjects were significantly higher than those in the normal and the lean group (P

Objective This study was designed to validate the utility of a population pharmacokinetic model established for vancomycin in patients with severe neurosurgical disease . Methods The clinical data including patient gender , age , body weight ,serum creatinine and albumin were collected retrospectively from patients in Nanjing Drum Tower Hospital to calculate the steady trough concentration of vancomycin using the previously established pharmacokinetic model .The predicted value was compared with the actual value .Results During the period from March 2013 to March 2014 ,53 blood samples with serum trough concentration of vancomycin were collected from 42 patients .The average trough concentration of vancomycin was 10 .9 mg/L (range from 1 .6 to 49 .1 mg/L) .The predicted trough level of vancomycin based on the population pharmacokinetic model was significantly correlated to the actual value(r=0 .857 ,P<0 .001) .The mean absolute percentage error was 0 .407 9 . The confidence interval was 9 .36‐14 .07 for the predicted values ,and 8 .92‐14 .32 for the actual values .Conclusions The pharmacokinetic model is valid and useful for planning intravenous dose of vancomycin in patients with severe neurosurgical disease .Large error (about 30% ) was observed in estimation of body weight due to coma .Reduced renal function following contrast agent and/or diuretic drug has an impact on the predicted results . The accuracy of prediction can be increased to nearly 70% after adjusting the covariates .

Objective To evaluate the conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) in diagnosis of splenic trauma including its grading diagnosis. Methods US and CEUS in 42 patients with splenic trauma confirmed by CT and/or operation were performed during 9.2004-10.2007. All the data were compared and analyzed retrospectively. Results Of 42 patients with splenic trauma, 28 cases were detected and 14 cases were missed on US examination, whereas, 40 cases were detected and only 2 mild cases were missed on CEUS examination. The detection rate of lesions with CEUS was significantly higher than that of US (P<0.001) . Ten cases in grading the injury were underestimated by US, however, none of them were underestimated by CEUS. CEUS had good concordance with CT and/or operation in grading diagnosis of 42 cases except two mild cases. Conclusions CEUS has very good concordance with CT and/or operation in detecting injury and grading the splenic trauma compared with conventional US. CEUS as a new imaging technology has made great advance of ultrasoongraphy in evaluation of splenic trauma including injury grading,and it is very useful in clinical application.

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.

Objective:To explore the association between interleukin(IL)-28B single nucleotide polymorphisms and natural outcome of hepatitis C virus.Methods:The IL-28B rs12979860 locus was genotyped in 266 HCV infected volunteer blood donors(107 spontaneous cleared and 159 chronic infection) and 97 healthy controls using Sanger sequencing assay.The difference in rs12979860 genotypes and allele frequencies between the six groups(107 spontaneous cleared and 159 chronic infection,266 HCV infection and 97 healthy controls,159 chronic infection and 97 healthy controls) were analyzed by statistics.Results:159 HCV chronic infection,107 spontaneous cleared and 97 healthy controls,were shown more CC genotype,accounting for 83.6%,95.3%and 86.6%,respectively, while the CT genotype accounted for 16.4%,4.7%and 13.4%respectively.No TT genotype was found.The CC/CT genotype was not significant difference between HCV infection and healthy controls,chronic infection and healthy controls(χ2=0.204,P=0.652;χ2=0.406,P=0.524),but between chronic infections and spontaneous clearance had statistically significant(χ2=8.474,P=0.004),the frequence of C allele in spontaneous cleared was higher than HCV chronic infection(χ2=7.949,P=0.005).Conclusion: The gene polymorphism of IL-28B rs12979860 is not related to HCV susceptibility,but there are differences in chronic infection and spontaneous cleared,showing the C allelic in favor of HCV spontaneous cleaed.

Objective To analyze variations of hepatic vein in healthy people with 64-slice spiral CT.Methods Seventy-five healthy subjects underwent multi-slice spiral computed(MSCT)hepatic venography.The anatomy of the junction of the hepatic veins with the inferior vena cava and the intrahepatic drainage territory of the hepatic veins and tributaries were evaluated.The hepatic veins were classified according to three anatomic classification(Nakamura's,Marcos's and Kawasaki's classification)methods respectively.Results There was a common trunk of the middle and left hepatic veins before joining the IVC in 86.7%(65/75)of the cases.In 13.3%(10/75)of the cases,the three main hepatic veins joined the IVC separately.The ratios of Nakamura's classification type A,B,C of hepatic veins were 49.4% (37/75),37.3%(28/75),and 13.3%(10/75)respectively.The ratios of Marcos's classification type A,B,C of hepatic veins were 56.0%(42/75),24.0%(18/75),and 20.0%(15/75)respectively. The ratios of Kawasaki's classification type Ⅰ,Ⅱ of hepatic vein were 40.0%(30/75)and 60.0% (45/75).Conclusion Multi-slice spiral CT hepatic venography can provide visualization of peripheral hepatic venous branches in details.

Objective To identify the rate of hepatitis B virus (HBV) reactivation and potential risk factors in hepatitis B surface antigen negative/hepatitis B core antibody positive patients with lung cancer receiving adjuvant chemotherapy without concomitant antiviral prophylaxis.Methods The records of 3280 patients with lung cancer who received adjuvant chemotherapy were retrospectively reviewed from January 2003 to December 2011.Among these patients,367 hepatitis B surface antigen negative/hepatitis B core antibody positive patients were analyzed for the HBV reactivation in this study.The HBV serology marker and biochemical tests of the 367 patients were performed.The data were analyzed by chi square test.Results Among 367 hepatitis B surface antigen negative/hepatitis B core antibody positive patients with lung cancer,14 patients suffered HBV reactivation.Univariate analysis showed that age≥70 years(x2 =13.003,P=0.019),abnormal liver computed tomography findings (x2 =11.225,P =0.026) and the amount of corticost eroids≥ 150 mg(x2 =7.008,P =0.033)were associated with HBV reactivation.However,gender and adjuvant chemotherapy regimens were not related with HBV reactivation.Conclusion HBV reactivation occurs in a proportion of hepatitis B surface antigen negative/hepatitis B core antibody positive patients with lung cancer during adjuvant chemotherapy.

Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness). The results indicated that bitter and slightly bitter amino acids have the greatest impacts on the sense of Spica Prunellae.
