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 observe the expression of c-fos mRNA and protein in fluoride treated mouse fibroblast (FB) and osteoblast (OB) and to further explore the effects of c-fos in the osteogenic action of FB. Methods Mouse FB and OB were divided into control group and six fluoride groups (0, 0.0001, 0.0010, 0.1000, 1.0000, 10.0000,20.0000 mg/L F-), and the levels of c-fos protein at 2,4,24,48,72 h and c-fos mRNA at 48 h were measured by using ELISA and RT-PCR methods. Results Compared with the control group, fluoride increased the content of c-fos protein obviously in all FB group(P<0.01); and it is increased in 0.0001,0.0010 mg/L groups at 48 h (0.73±0.04, 0.64±0.14) and 0.0001 mg/L group at 72 h(0.70±0.17) in OB compared with the control group (0.32±0.04,0.27±0.05, P<0.01). Compared with the control group (0.95±0.11), RT-PCR revealed an increasing tendency of the expression of c-fos mRNA at 48 h in FB (1.06±0.16, 1.06±0.12,1.12±0.16,1.04±0.15,1.04±0.10,1.15±0.29), but the difference was not statistically significant(P>0.05); however, a statistically significant difference(P<0.01) of c-fos mRNA in 20.0000 mg/L group(1.40±0.17) in O B was found compared with the control group (1.06±0.06). Conclusion The higher expression of c-fos mRNA and protein in FB induced by fluoride may play an important role in the transformation of osteoblastic phenotype as well as increase the osteogenesis ability in FB.

Objective To observe endoplagmic reticulum stress in bone tissue of fluomsis rats and further explore the pathogenesis of skeletal fluorosis.Methods 48 Wistar rats were divided into 4 groups according to their body mass.The control and low.calcium group were fed with normal diet(0.79%calcium)and low-calcium diet(0.79%calcium)respectively,and both drank tap water(sodium fluoride concentrations＜1 mg/L).High fluoride and low.calcium plus high-fluoride groups were fed with normal diet(0.79%calcium)and low-calcium diet (0.79%calcium)respectively,and both drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L).During experimental period,rats were measured body mass once a week with a stand diet and water available ad libiturn.The experimental period was 3 months.The biochemical techniques were used to test the indicators of oxidative stress and ALP in seFum of fluorosis rats.The total RNA was extracted from the one side of the femur,and the transcription level of Bip,Xbp1,CHOP and PDI were investigated by reverse transcription polymerase chain reaction(RT-PCR).Results The level of MDA in serum of low-calcium plus high-fluoride group wag higher than that of the control[(14.74±3.11)μmol/L vs(10.15±1.96)μmol/L,P＜0.05];the activity of GPx was ma~edly higher in hish-fluoride group compared with the control[(3.87±0.41)×103 U/L vs(2.85± 0.55)×103 U/L,P＜0.05];the level of uric acid in sel'um was significantly lower both in high-fluoride group and low-calcium plus high-fluoride group compared with the respective control and the low-calcium group[(73.95± 9.52)μmol/L vs(110.43±25.48)μmol/L,(54.32±22.09)μmol/L vs(101.71±17.01)μmol/L,P＜0.05]. The activity of ALP wag obviously higher in low-calcium plus high-fluoride group compared with the control [(24.77±4.57)×103U/L vs (12.91±3.97)×103U/L,P＜0.01)].The mRNA expression of Bip/GAPDH in bone tissue was markedly higher in bone of high-fluoride group and low-calcium plus high-fluoride group compared with the control(1.38±0.24,1.35±0.12 vs 1.14±0.06,P ＜ 0.05). The expression of Xbp1/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control and the low-calcium group (1.48±0.20 vs 1.02±0.25,1.07±0.25,P ＜ 0.05 or ＜ 0.01);and CHOP/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control(0.84±0.18 vs 0.52±0.07,P ＜ 0.05 ). Conclusions Accelerated osteogenetic action is seen in fluorosis rats,accompanied by oxidative stress and bone endoplasmic reticulum stress,which is likely involved in the pathogenesis of skeletal fluorosis.
