Background and purpose:The signal transducers factor and activator in transcription 3(STAT3) is a recently studied gene from a variety of solid tumors such as breast, stomach, and ovarian cancer, in which the increase of abnormal expression and activity are accompanied.The aim of this study was to investigate the effects of eukaryotic vectors that express short hairpin RNA(shRNA) in signal transducers and activators of STAT3 on chemosensitivity of human ovarian cancer SKOV3 cells.Methods:Vectors containing shRNA targeting STAT3(pSTAT3-siRNA) were constructed and transfected into SKOV3 cells.These vectors were then divided into 3 groups:SKOV3, SKOV3NS, and SKOV3siRNA.The mRNA and protein expressions of STAT3 were determined by RT-PCR and Western blot, respectively.The growth inhibition and apoptosis rates of the different group cells under chemotherapeutic agents such as cisplatin(20 ?mol/L) were measured by MTT assay and flow cytometry(FCM).Results:MTT assay growth inhibition rates in the tumor cells of the SKOV3 group, SKOV3NS group and SKOV3siRNA group had inhibition rates of 0.46?0.13, 0.44?0.11 and 0.71?0.12.Compared with the SKOV3, SKOV3NS and SKOV3siRNA group, there was a marked increase of SKOV3siRNA group in inhibition rate of cells.The differences were also statistically significant(P0.05).The SKOV3 group, SKOV3NS group and SKOV3siRNA group's cell apoptosis rates were 18?4, 18?3 and 35?4, respectively.However, the SKOV3 group, SKOV3NS group, and SKOV3siRNA group cell apoptosis were significantly increased and the differences were statistically significant(P0.05).The results for the SKOV3 group, SKOV3NS group and SKOV3siRNA in cell STAT3 mRNA were 0.50?0.08, 0.48?0.07 and 0.31?0.09.With the SKOV3 group, SKOV3NS group, SKOV3siRNA group of cells in STAT3 mRNA, its expression in the lungs were significantly lower and the differences were statistically significant(P0.05).SKOV3 group, SKOV3NS group and SKOV3siRNA group of cells checked the results of STAT3 protein were 0.54?0.09, 0.56?0.08 and 0.32?0.09, respectively.The SKOV3 group, SKOV3NS group, and SKOV3siRNA group in STAT3 protein expression was significantly lower and the differences were statistically significant(P0.05).Conclusion:The STAT3 specific shRNA expression vector could effectively suppress the expression level of STAT3 gene in SKOV3 cells as well as enhance their sensitivity to cisplatin.

Objective To retrospectively analyze medical data of patients with colorectal cancer (CRC) so as to provide evidence for clinical use of opportunistic screening.Methods A total of 2450 CRC patients (male 1377,female 1073) who were treated at five hospitals in North China during October 2001 and September 2011 and had complete medical records and pathological results were recruited.The correlations of incidenceofCRCwithage,gender,tumorlocationandhistologicaltypeswere analyzed.Results Of all the CRC patients,those less than 50 years old accounted for 18.14％ ; and the incidence of CRC was substantially increased in those over 50 years old.Seventy-three percent of tumor occurred at the rectum and sigmoid colon,6％ at descending colon,7％ at transverse colon and 14％ at ascending colon.Moderately,well or poorly differentiated adenocarcinoma accounted for 50.33％,40.35％and 9.32％,respectively.Histological differentiation was not correlated with age and gender ( P ＞ 0.05 ).Conclusions Age and gender should not be considered a determination of opportunistic screening for CRC.Colonoscopy is recommended as an alternative CRC screening procedure.

Objective To identify clinicopathological features of high MSI (MSI-H).Methods We enrolled 150 patients,standard microsatellite loci (BA T25,BA T26,D2S123,D5S346,D17S250) were amplified by polymerase chain reaction(PCR) with fluorescent primers,and the PCR products were analyzed by GeneMapper software;age at diagnosis,gender and site were obtained;various pathological features were observed by light microscopy;the expression of tumor infiltrating lymphocytes (CD4~+ and CD8~+) was detected by immunohistochemistry.Using a stepwise logistic regression model,a formula was generated that could be used to calculate the probability of a colorectal carcinoma being MSI-H based on pathological features.Results Among 150 cancers,MSI-H was 13.33%.Independent identifiers inclucle poor differentiation,histologic heterogeneity,Crohn's-like reaction and tumor-infiltrating lymphocytes,logistic regression formula shows a sensitivity of 70.0% and a specificity of 99.2% and a accurate ratio of 95.3% for MSI-H.Conclusion MSI-H phenotype cancer is a type of nonfamilial colorectal cancer with specific pathological features,Clinicopathological features can efficiently identify MSI-H colorectal cancers.

Objective To evaluate the effect of various methods of fecal exfoliated cell testing for screening of colorectal cancer.Methods The stool samples from 814 patients who underwent colonoscopy were collected for fecal exfoliated cell testing using diarrhea feces,twice naturally evacuated feces,magnetic separation or naturally evacuated combined with diarrhea feces.The fecal exfoliated cells were isolated and examined cytologically.The DNA quantitative analysis and gene detection were carried out.Fecal occult blood test was simultaneously performed in twice naturally evacuated feces and naturally evacuated combined with diarrhea feces.Results The sensitivity and specificity of exfoliated cells testing for colorectal Cancer was 66.27%(112 of 169 cases of colorectal cancer)and 99.56%(225 of 226 normal subjects),respectively.There was no correlation of positive rate with differentiations of colorectal cells or Duke's stages(P＞0.05).The nuclear DNA quantitative analysis showed that the sensitivity for detecting cancer was 76.09%for twice naturally evacuated feces and 68.29%for naturally evacuated combined with diarrhea feces,which was superior than diarrhea feces(26.31%)and magnetic separation (43.24%).The positive rate of genes detected in carcinoma tissues concordant with fecal exfoliated cells testing were 83.33%(25/30)for p53,9/10 for APC and 9/10 for K-ras.The sensitivity of cytology was higher than gene detection.The sensitivity of cancer detection was higher in combining exfoliated cells test with fecal occult blood test(93.10%)than exfoliated cells test(73.56%)or fecal occult blood test (80.46%)alone(P＜0.05).Conclusions Fecal exfoliated cells test is an effective method for screening of colorectal cancer.It is the best option for detecting cancer by twice tests of fecal exfoliated cells with liquid-based thin-layer cytological test,and combined with fecal occult blood test.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.

Objective:To evaluate the anxiety and depression symptoms of burning mouth syndrome (BMS), and to explore risk factors to BMS.Method:In this case-control study,147 patients with BMS and 140 sex-and age-matched healthy volunteers were recruited.Three questionnaires were used to collect information of psychical and mental condition.The Self-Rating Anxiety Scale (SAS)and Self-Rating Depression Scale (SDS)were applied to evaluate symptoms of anxiety and depression.The scores of SAS and SDS were statistically analyzed by t-test.The risk factors of BMS were statistically analyzed by Chi-square test and logistic regression analysis.Result:The scores of SAS and SDS were higher in the patients with BMS than in the controls [SAS:(44.4 ±9.9)vs. (35.7 ±6.2);SDS:(48.1 ±11.6)vs.(37.5 ±8.9)].The risk factors of BMS included ischemic stroke (OR =4.46,95%CI:1.87 -10.95),low level of education (OR =1.91,95%CI:1.04 -3.49),anxiety symptom (OR =8.12,95%CI:2.60 -25.37)and depression symptom (OR =2.57,95%CI:1.26 -5.27).Conclusion:BMS is a multi-factorial disease.It indicates that ischemic stroke,lower level of education,anxiety symptom and depression symptom are the risk factors of BMS.A positive association could be established between psychological alterations and BMS.According to these findings it can be assumed that mental factors should be taking into account in the etiologyof BMS.It should be advocated to treat BMS patients by psychotherapy.

Objective: To explore the clinical effect of Shufeng Tongqiao and Yifei Jianpi prescription in the treatment of allergic rhinitis. Methods: From September 2015 to October 2017, 60 patients with allergic rhinitis in the Traditional Chinese Medicine Hospital of Tongxiang were selected according to include and exclude standards.The patients were randomly divided into two groups according to the digital table, with 30 cases in each group.The control group was treated with conventional western medicine: loratadine tablets combined with budesonide nasal spray.The treatment group was given traditional Chinese medicine on the basis of the control group.Before and after treatment, the nasal congestion, runny nose, nasal itching, sneezing four indicators were recorded in the two groups.And nasal discharge, tears flowed pharyngeal from eye pain, oral cavity on the forehead, nose, or pain, headache, five secondary indicators, as well as in the case of a change rhinitis, quality of life questionnaire were collected.The data were statistically analyzed. Results: Before treatment, there were no statistically significant differences in the main symptoms, secondary symptoms, serum IgE and quality of life between the two groups (all P>0.05). After 3 months of treatment, all the indicators in the two groups were significantly improved compared with those before treatment, and the differences were statistically significant (all P<0.05). In addition, the improvement of main symptoms and serum IgE in the treatment group were better than those in the control group, and the differences were statistically significant (z/t=-2.708, -2.033, -3.757, -2.208, -2.432; P=0.007, 0.042, 0.000, 0.027, 0.018), but there were no statistically significant differences between the two groups in terms of subtypes and quality of life improvement (P=0.488, 0.448, 0.519, 0.228, 0.278, 0.338). After 1 year of follow-up, the mean scores of each group were analyzed and compared.The indicators in the treatment group showed a different degree of recovery after 3 months of treatment.However, compared with before treatment, the indicators were still significantly improved.The scores of nasal obstruction, runny nose, nasal itching, sneezing, quality of life, and serum IgE in the treatment group were (1.13±0.81)points, (1.00±0.94)points, (0.93±0.74)points, (1.00±0.74)points, (6.13±2.30)points, (92.23±12.55)points, compared with those before treatment, the differences were statistically significant (t/z=-5.575, -5.222, -6.281, -5.918, 5.633, 9.199, all P<0.01). Compared with the control group, all indicators were significantly better, the differences were statistically significant (z/t=-2.388, -2.390, -2.738, -2.350, 4.800, 4.022, 4.444, 4.356, 5.934, -2.023, -4.381; P=0.017, 0.017, 0.006, 0.019, 0.028, 0.045, 0.035, 0.037, 0.015, 0.048, 0.000). After 3 months of clinical treatment and 1 year follow-up analysis, the total effective rate of the treatment group was 93.3%, that of the control group was 86.7%, the difference between the two groups was statistically significant (Z=-2.221, P=0.026). Conclusion The clinical efficacy of Shufeng Tongqiao and Yifei Jianpi prescription combined with western medicine in the treatment of allergic rhinitis is more significant than conventional western medicine alone, and the long-term efficacy is significant, which can effectively reduce the symptoms of patients, improve the quality of life of patients, and significantly reduce the level of serum IgE.

Objective:To investigate the inhibitory effect of curcumin on oxidative stress in BCG-infected macrophages based on the Nrf2 pathway.Methods:THP-1-derived macrophages were infected.The experiment was divided into control group,BCG group,BCG+curcumin group and BCG+curcumin+ML385 group.Cellular ROS fluorescence intensity were observed under a fluores-cence microscope;Glutathione(GSH)levels were measured by Colorimetry;Western blot was used to detect the protein expressions of Nrf2,HO-1 and NQO1;MTT was used to detect the proliferation rate of macrophages.Results:BCG infection significantly enhanced ROS fluorescence intensity,reduced cell GSH content(P<0.01),inhibited protein expressions of Nrf2,HO-1 and NQO1,at the same time inhibited cell proliferation(P<0.01);curcumin significantly weakened ROS fluorescence intensity,increased GSH level(P<0.05),promoted Nrf2,HO-1 and NQO1 protein expressions and cell proliferation(P<0.01);Nrf2 inhibitor ML385 reversed the effect of curcumin.Conclusion:Curcumin can alleviate BCG-induced oxidative stress in macrophages by increasing the expression of Nrf2 and inducing the transcription of downstream antioxidant molecules.

Objective To investigate the efficacy and safety of 6-month and 12-month oral dual-antiplatelet therapy This work was supported by the National Key Technology Research and Development Program in the Twelfth Five-year Plan of China (2011BAIl1B07) and the Military Clinical Key Technology and Development Program (2010gxjs001)(DAPT) on patients implanted with biodegradable polymer-coated and drug-eluted long stents (BP-DES).Methods In the I-LOVE-IT 2 trial,574 patients implanted with biodegradable polymer-coated and sirolimus-eluted long stent (BP-SES) (total stent length ≥50mm) were randomized to accepting either 6-month (n=270) or 12-month (n=304) DAPT.The primary endpoint of present study was 12-month target lesion failure (TLF),including cardiac death,target vessel myocardial infarction and clinically indicated target lesion revascularization (CI-TLR).The major secondary endpoint was 12-month net adverse clinical events (NACE),including all-causes of death,myocardial infarction,stroke,all revascularization (CI-TLR plus clinically indicated nontarget lesion revascularization) and bleeding.Results For the patients implanted with BP-SES of total stent length≥ 50mm,the total stent length was 73.0 ± 22.5mm and 69.8 ± 19.4mm in the 6-month DAPT group and 12-month group,respectively (P=0.07).No significant difference existed in the incidence of 12-month TLF between 6-month DAPT group and 12-month DAPT group (11.1％ vs.9.2％,P=0.47).The incidence of NACE was similar between the 2 groups (21.9％ vs.19.7％,P=0.57).The incidence of revascularization was lower in 12-month DAPT group (5.6％) than in 6-month DAPT group (11.1％,P=0.01).Furthermore,6-month landmark analysis showed that 12-month DAPT was associated with significantly lower risk of TLF (2.6％ vs.6.3％,P=0.03) at a cost of slightly increased risk of all bleeding events (1.6％ vs.0.7％,Log-rank P=0.32) between 6 and 12-months compared to 6-month DAPT.Conclusions In patients treated with BP-SES of total stent length ≥ 50mm,12-month DAPT have similar impacts on 12-month clinical outcomes except for all revascularization.However,12 months DAPT decreased the incidence of TLF and total revascularization between 6 months to 12 months after PCI.
