Objective To investigate the association between the expression of heparanase(Hpa) and the invasion of choriocarcinoma by studying the expression of Hpa in human choriocarcinoma cell lines JEG-3 and JAR and human chorionic villous tissues.Methods(1)Matrigcl invasion assays were used to detect in vitro invasive ability of JEG-3 cells and JAR cells.(2)Expression of Hpa protein in the human chorionic villous tissues and choriocarcinoma cell lines(JEG-3 cells and JAR cells)were detected by immunocytochemistry and western blot.Results(1)The invasive cell number was significantly larger in JEG-3 cells than in JAR cells(191?17 vs 106?13,P

Asaprimarilyused plasticizerin polyvinyl chloride,d(i2-ethylhexy)lphthalate(DEHP)is extensively used in consumer products,flooring and wall coverings,food contact applications,and medical devices.Because DEHP has been detected in waters,soils and air,and its metabolites have also been detected in human urinary,sufficient evidences show that DEHP is ubiquitous in the environment worldwide.DEHP is already in the blacklist of priority pollutants in water in China.Many researches indicate that DEHP is one kind of endocrine disrupting chemicals in animals,with carcinogenicity,teratogenicity and mutagenicity.Based on the researches and review on DEHP,this paper principally discussed the environmental level,metabolism and biological markers of DEHP,as well as the research progress on human health effects.

Objective To observe the expression and role of HSP70 in human epidermis and cutaneous neoplasms.Methods 56 cases of epidermis tumors,including 29 biopsy samples from basal cell carcinoma, 27 from squamous cell carcinoma,and 30 from normal human skin were investigated. HSP70 expression was examined by immunohistochemical SABC staining with specific monoclonal antibodies.Results The expression of HSP70 was detectable in the cytoplasm throughout the epidermal cell layers in normal human epidermis,HSP70 expression in the tumor cells in basal and squamous cell carcinomas was reduced (P

Objective To investigate the clinicopathological features,survival,and the impact of postoperative adjuvant radiotherapy on the ovarian function in patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer.Methods One hundred and eighty-six patients who were admitted to our hospital from 2000 to 2011 were retrospectively analyzed.An equal number of patients older than 35 years of age with cervical cancer within the same period were used as stage-marched controls.The Kaplan-Meier method was used to calculate the survival rates,and the log-rank test was used for pairwise comparison and univariate prognostic analyses.The Cox proportional hazards model was used for multivariate prognostic analyses.Results The patients less than or equal to 35 years of age had a significantly higher incidence of non-squamous carcinoma but significantly lower incidence rates of deep stromal invasion and lymph-vascular space invasion (LVSI) compared with the control group (P =0.000;P =0.008;P =0.000).Though young patients had significantly higher 5-year disease-free survival (DFS) and overall survival (OS) rates than the control group (93.7％ vs.84.5％,P=0.005;96.1％ vs.89.5％,P=0.033),age was not an independent prognostic factor (P =0.202;P =0.950).Among patients less than or equal to 35 years of age,lymph node metastasis and LVSI were independent prognostic factors for DFS (P =0.000;P =0.000),while LVSI and initial tumor size were independent prognostic factors for OS (P =0.000;P =0.000).There was no significant difference in the incidence of normal ovarian function between young patients treated with and without adjuvant radiotherapy after ovarian transposition (63％ vs.73％,P =0.422).Conclusions Patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer have a better prognosis than the control group.However,age is not an independent prognostic factor.Postoperative adjuvant radiotherapy will not impair the function of transposed ovaries.

To analyze the data of 284 smoking patients visiting the clinic during January 2009 to December 2011.There were 273 males and 11 females with a mean age of 49 years and an average length of 26 years of smoking 24 cigarettes per day.The average volume fraction of exhaled carbon monoxide was 16 × 10-6.The average score of Fagerstrom test of nicotine dependence (FTND) was 5.The importance,confidence and preparation of quitting smoking were graded at an average of 8.5,6.7 and 7.6 respectively.Abstinence rate was 66.1％ at 1 month and 50.9％ at 3 months.A particular focus was placed upon those smokers with more serious nicotine dependence and longer smoking years.They knew much about the importance of smoking cessation,but there was a lack of confidence.Smoking cessation improves abstinence rate via behavioral counseling,psychotherapy and medication.We should strengthen publicity of smoking cessation and smoking cessation clinic to attract more patients with heightened confidence through treatment.

Objective To investigate the correlation of diastolic blood pressure (DBP) ＜70mm Hg and isolated systolic hypertension (ISH) with coronary atherosclerosis (CAS) and coronary heart disease (CHD) in elderly patients and to analyze the independent risk factors for low DBP.Methods A total of 246 elderly patients with untreated ISH who underwent coronary angiography were divided into the low DBP group (n=102) and the non-low DBP group (n=144) according to DBP level.All clinical and angiographic data were collected and the retrospective analysis was performed to assess the risk of CAS and CHD in patients with low DBP and to analyze the risk factors for low DBP.Results There were no significant differences in systolic pressure level between the low DBP group and the non low DBP group [(156.2±15.6) mmHgvs.(154.4±14.2) mmHg,t=0.93,P＞0.05],while pulse pressure level was significantly higher in the low DBP group than in the non-lowDBPgroup [(91.3±±17.7) mmHgvs.(72.9±15.1) mm Hg,t=8.54,P＜0.01].Stepwise logistic analysis showed that age,diabetes and smoking were independent risk factors for low DBP.After adjustment for age,gender and other common risk factors,low DBP was independently associated with CAS and CHD (OR =1.72 and 1.44,95％ CI:1.082.72 and 1.04-1.99,respectively,both P＜ 0.05).Conclusions Low DBP is independently associated with CAS and CHD in elderly patients with untreated ISH.Age,diabetes and smoking are the independent risk factors for low DBP.

Objective To investigate the efficacy and prognostic factors in patients with stage Ⅰ b and Ⅱ a cervical carcinoma by radical radiotherapy.Methods Between January 1999 and January 2012,108 patients with stage Ⅰ b and Ⅱ a cervical carcinoma received radical radiotherapy in Cancer Hospital,Chinese Academy of Medical Sciences were included and analyzed retrospectively.Patients of stage Ⅰ b1,Ⅰ b2,Ⅱa1 and Ⅱa2 were 18 (16.7％,18/108),38 (35.2％,38/108),33 (30.6％,33/108) and 19 (17.6％,19/108),respectively.Results The 5-year overall survival rate was 76.2％ and the 5-year disease free survival rate was 75.6％.Totally 25 (23.1％,25/108) patients developed recurrent disease,16 of them (64％,16/25) had local recurrences,6 (24％,6/25) had distant metastases and 3 cases had both local recurrence and distant metastases.Among patients with recurrent disease,23 died and 2 survive with tumor.Totally 24 patients died,23 of them died due to tumor recurrence and the other one died of other reason.The univariate analysis showed that,lymph node metastasis,squamous cell carcinoma antigen (SCC) levels before treatment,SCC levels after treatment 1 month had relation with overall survival time in patients with stage Ⅰ b and Ⅱ a cervical carcinoma (all P ＜ 0.05).The multivariate analysis showed that,lymph node metastasis and SCC levels after treatment 1 month were the independent prognostic factors for overall survival time for the cervical squamous cell carcinoma (OR =2.5,4.4 ; all P ＜ 0.05).Conclusions By means of radical radiotherapy,stage Ⅰ b and Ⅱ a cervical carcinoma patients with lymph node metastasis and SCC levels≥ 1.5 mg/L after treatment one month have poor prognosis.While,stage Ⅰ b and Ⅱ a patients with concurrent chemoradiotherapy after neoadjuvant chemotherapy did not affect the prognosis.The 5-year survival rate with concurrent chemoradiotherapy was higher than that of radiotherapy.
