OBJECTIVE:To observe the influence of capecitabine combined with radiotherapy on postoperative survival rate, relapse rate and survival quality of elderly patients with rectal cancer at Ⅱ-Ⅲ stage. METHODS:110 patients with rectal cancer atⅡ-Ⅲ stage were selected and randomly divided into control group and observation group with 55 cases in each group. Both group received radical resection of rectal carcinoma. Control group was given three dimensional conformal radiation therapy(3DCRT)af-ter operation;observation group was additionally given capecitabine 1 500 mg/m2,d1-14,qd,on the basis of control group. A treatment course lasted for 21 d,and both groups received 2 courses of treatment and followed up for 3 years. The survival rate and metastasis and recurrence rate of 2 groups were compared as well as KPS score before and after treatment. Toxic reaction of 2 groups was also observed. RESULTS:The follow-up total survival rate and disease-free survival rate of observation group were 89.09%and 76.36%,which were significantly higher than 74.55%and 54.55%of control group;the distant metastasis rate and lo-cal recurrence rate were 12.73% and 5.45%,which were significantly lower than 30.91% and 21.82%,with statistical significance (P<0.05). KPS score of 2 groups were increased significantly,between 2 groups before and after treatment ,with statistical signifi-cance(P<0.05);Comparison between groups(P>0.05). There was no statistical significance in the incidence of nausea and vom-iting,diarrhea and urinary tract reaction between 2 groups (P>0.05);but the incidence of bone marrow arrest in observation group was significantly higher than control group(P<0.05). CONCLUSIONS:Capecitabine combined with 3DCRT can effectively improve postoperative distant survival rate of patients with rectal cancer at Ⅱ-Ⅲ stage,and reduce the metastasis and recurrence risk;do not lower life quality and induce serious adverse reactions.

Objective To explore the multiple risk factors for family lifestyle of children with congenital heart defects (CHDs) in Shaanxi Province, China. children and their parents. The univariate and multivariable logistic regression models were used to analyze the influence of risk factors related to parents' lifestyle on CHDs. Results Several possible risk factors were found for CHDs, including fever (OR=4.465, P=0.017), pesticides contact (OR=2.234, P=0.083), passive smoking during pregnancy (OR=20.529, P=0.007) and father's smoking (OR=3.342, P=0.005); fever (OR=2.428, P=0.012) and passive smoking during pregnancy (OR=1.201, P=0.037) were also correlated with ventricular sepal defect (VSD). Conclusion Fever, pesticides contact and passive smoking are associated with CHDs during pregnancy. We should focus our attention on health care during pregnancy to avoid the above-mentioned risk factors and call on parents to hold on to a good healthy lifestyle.

Objective To explore the epidemiology and risk factors of toenail onychomycosis among traffic police-men in Tianjin, and to prevent and control its prevalence. Methods Epidemiological surveys were performed to a total of 1 270 traffic policemen during physical examination in Public Security Hospital in Tianjin using cross-section study. Fungi in feet and the prevalence of toenail onychomycosis were examined simultaneously during questionnaires. Logistic regression of single factor and multiple factors were applied to analyze the risk factors. Results The prevalence of toenail onychomyco-sis in Tianjin traffic policemen is 32%. Age (OR=1.455), police boots (OR=1.047), history of tinea pedis (OR=7.521) and his-tory of diabetes (OR=1.820) are the main risk factors. Conclusion The prevalence of onychomycosis among Tianjin traffic policemen is high. Synthetic and effective interventions should be employed to deal with the risk factors.

Objective To investigate the mechanism of the radiosensitivity effect of Cox-2 gene in esophageal cancer.Methods Cox-2 specific siRNA was constructed and transfected to EC9706 cells to downregulate intracellular Cox-2 expression.The expressions of MMP-2,Bcl-2 mRNA,AKT and phosphorylated AKT proteins were assayed after radiation.Colony formation,cell proliferation,apoptosis and cell invasion in vitro were examined as well.One-way ANOVA method was used to analyze the data.Results Affter 2 and 4 Gy irradiation,a significant increase in the mRNA expression of Bcl-2 was observed in the Cox-2 up-regulation group (F =3.36,4.32,P ＜ 0.05).In the group of Cox-2 downregulation,the expression of MMP-2 mRNA was significantly reduced(F =3.86,8.09,P ＜ 0.05).Affter irradiation,a significant decreaseof Bcl-2 mRNA (F =3.73,5.64,P ＜ 0.05) as well as an increase of Bax(F =7.03,7.42,P ＜ 0.05) was detected,and the levels of total and phosphorylated AKT proteins had the highest level in the Cox-2 upregulation group and had the lowest level in the Cox-2 downregulation group.In the Cox-2 downregulation group,the apoptosis induction obviously increased with dose (F =317.40,P ＜ 0.05),and the proportion of cells in Go-G1 phase gradually increased but the proportion of cells in S and G2-M phases decreased,concomitant with the obvious suppression of cell proliferation,in addition,cell invasion was decreased.Conclusions Downregulation of intracellular Cox-2 mRNA expression,concomitant with subsequent downregulation of MMP-2 and Bcl-2 and upregulation of Bax,resulted in reduction of the invasion and metastatic capabilities of tumor cells,and induction of Go-G1 phase arrest and apoptosis.Downregulation of AKT and phosphorylated AKT (pAKT) protein expression might also interfere with the capability of the PI3K/Akt signal transduction pathway to resist radiotherapy.

Objective To assess the tolerance of elderly patients with esophageal carcinoma to chemoradiotherapy through.Methods A retrospective analysis of 596 elderly patients with esophageal carcinoma receiving chemoradiotherapy was conducted.Patients were divided into radiachemotherapy group and radiotherapy group,and according to age,patients were divided into four age groups (aged 70-74,75-79,80 80 and 85years and over).The tolerance to treatment was assessed by Charlson index.Results 185 patients completed chemoradiotherapy,113 patients reduced the dose of chemotherapy (reduction group),81 patients unfinished chemoradiotherapy (unfinished CRT group),160 patients completed radical radiotherapy alone (unfinished RT group),and 57 patients incompleted radiotherapy.Further analysis found that the tolerance to treatment in reduction group had significant differences between patients aged ≥ 75 years and ＜ 75 years (x2 =6.815,P=0.009),and between WIC ≥ 1 and ＜ 1(x2 =10.636,P=0.001); the tolerance to treatment in unfinished CRT group had significantly differences between aged ≥ 80 years and ＜80 years (x2 =63.842,P=0.000),and between WIC =0,1 and ≥ 2 (x2 =21.153,P=0.000).Conclusions Further age re-grouping and WIC assessment is necessary before treating esophageal cancer patients.Reduction of therapy dosage is more beneficial for patients aged ≥ 75 years and WIC≥1,and greater caution is required in chemotherapy for patients aged ≥ 80 years and WIC＞1.

Objective To investigate the effect of the extent of postoperative prophylactic radiotherapy after radical surgery on the long-term survival in patients with thoracic esophageal carcinoma.Methods A retrospective analysis was performed on the clinical data of 201 patients with thoracic esophageal cancer who received postoperative prophylactic radiotherapy after radical surgery from 2000 to 2007.The effect of the extent of radiotherapy on survival was evaluated,and the possible prognostic factors were subjected to multivariate Cox regression analysis.The Kaplan-Meier method was used to calculate overall survival (OS) rates,and the log-rank test was used for survival difference analysis.Results The 5-year follow-up rate was 97.0％.The OS rates for patients who received radiotherapy to the whole mediastinum,whole mediastinum + lymph nodes along the left gastric artery,whole mediastinum + bilateral supraclavicular regions,upper and middle mediastinum + bilateral supraclavicular regions,and whole mediastinum + bilateral supraclavicular regions + lymph nodes along the left gastric artery were 21.7％,37.1％,38.7％,34.8％,and 19.8％,respectively (P =0.406).Multivariate analysis showed that postoperative N stage was the independent prognostic factor (P =0.009).After prophylactic irradiation,metastases to the supraclavicular lymph nodes,lymph nodes in the upper and middle mediastinum,and abdominal lymph nodes were observed in 11,34,and 10 patients,respectively.Conclusions The extent of postoperative prophylactic radiotherapy after radical surgery for thoracic esophageal carcinoma only includes upper and middle mediastinum and bilateral supraclavicular regions.
