Objective To compare the treatment effects and toxicity of late co urse accelerated hyperfractionation radiotherapy (LCAFR), LCAFR plus concurren t chemotherapy (LCAFR+C) and conventional fractionation radiotherapy(CFR) on esop hageal cancer. Methods 150 patients with squamous carcinoma of thoracic esophag us were divided randomly into three groups: 1.CFR group, patients were irradiate d 2.0?Gy/f, 5 times a week, to a total does of 60?Gy. 2. LCAFR group, patients wer e first irradiated with CFR to 30?Gy, then followed by 1.5?Gy/f bid, at more t han 6 hours' interval, to the total dose of 60?Gy. 3.LCAFR+C group: The radiotherap y technique was the same as the LCAFR group, but weekly 20 mg DDP and 500 mg 5-Fu wer e added simultaneously for 5 weeks. Results All three groups completed their tre atment course. Of CFR, LCAFR and LCAFR+C groups, the 1-,2-,3- and 4-year sur viva l rates were 54%, 30%, 18%, 18%; 76%, 56%, 44%, 42% and 82%, 62%, 50%, 44%. The 1-,2-,3- and 4-year local control rates were 40%, 32%, 26%, 24%; 72%, 60%, 5 6%, 54% and 78%, 66%, 60%, 56%, with obvious better results in the latter two groups (P0.05). The acute toxic effect was severer in the LCAFR+C g roup than in the other two, with the difference significant between the LCAFR+C and CFR group, bu t not between the LCAFR and CFR group. The tolerance of the patients to LCAFR wa s better than that of LCAFR+C group. There were no significant differences in la te complications and causes of death between the three groups. The main cause of death was local recurrence and uncontrolled primary disease, which were signifi cantly lower in the LCAFR and LCAFR+C groups than in the CFR group. Conclusions Both late course accelerated hyperfractionation radiotherapy and late course acc elera ted hyperfractionation radiotherapy plus chemotherapy can significantly improve the local control and survival of esophageal cancer, but the latter has increase d toxicity. Concurrent small dose chemotherapy can not lowered the remote metas tatic rate.

Objective To explore the applications and effect of experience-based health education in maternal nursing in community.Methods According to the random number table,150 women pregnant for the first time were divided into control group and observation group with 75 in each group. In the control group,the traditional method for health education was used and in the observation group the experience-based teaching based on traditional health education.The two groups were compared in terms of the awareness rate of knowledge about maternal and infant health care and the incidence of postpartum depression.Result The awareness of knowledge about maternal and infant health care in the observation group was significantly higher than that of the control group and the incidence of postpartum depression in the observation group was significantly lower than that of the control group(P<0.01).Conclusion Experience-based health education can improve the level of knowledge about maternal and infant health care and reduce the incidence of maternal postpartum depression.

OBJECTIVE To discuss the related factors of toxigenic Helicobacter pylori(Hp) infection among adult population in Futian District,Shenzhen.METHODS A total of 1164 adults who had health examination in community centers were investigated through questionnaire and detected Hp antibodies.RESULTS The Hp and toxigenic Hp infection rates among them were 45.5% and 14.2%.Among them 46.3% and 14.8% were in males,and 44.7% and 13.4% in females.People less than 60 years old had higher incidence of Hp and toxigenic Hp,but decrease in people rnore than 60 years old.Hp and toxigenic Hp infection rate in married people were higher than those of unmarried.In workers,farmers and doctors were higher than staff and other occupations.The incidence were higher in drinking raw water than those drinking boiling water.in taking antibiotics before serologic examination were lower than no taking antibiotics;in peptic ulcer disease were higher than in no peptic ulcer disease;in per capita housing area over 6 m2 were higher than less 6 m2.CONCLUSIONS The infection rates of Hp and toxigenic Hp among our adult population are low,and positively correlated with age but gender.The social environment such as living condition,economic income,culture level and residential density maybe influence the infection of Hp.The route of transmission of Hp is unknown yet,water perhaps is an important dissemination medium.

Objective To explore the effects of empowerment education model on glycemic control and self-management behavior of community patients with diabetes. Method A total of 120 diabetics from 2 different communities were set as the observation group and control group. The control group was treated by routine medications and health education and the observation group was intervened with empowerment education model. After intervention for 6 months, the patients′blood glucose index and the diabetes self-management behavior were assessed and compared by scale of the diabetes self-care activities (SDSCA) between the two groups. Result By the end of the study, the glycemic index and SDSCA score in the former group were both significantly decreased than those in the control group (P<0.05), indicating the patients in the experiment group had better glycemic control and self-management behaviors compared with those in the control group. Conclusions Empowerment education model can arouse the internal motivation of patients to change their behaviors from passive to active acceptance in the health education. Empowerment education model can enhance diabetes patients′self-management conduct and the glycemic level.

Objective:To investigate the status quo of psychological contracts and influencing factors among members of the "1+N" family doctor teams in Shenzhen and to explore the impact of psychological contracts on job burnout.Methods:This cross-sectional study was conducted from September 30 to October 31, 2022 among 361 members of 92 family doctor teams from 92 community health service centers which provided family doctor team service in Shenzhen city. A self-designed general information questionnaire, an employee psychological contract questionnaire (including organizational responsibility and personal responsibility dimensions), and a job burnout scale (including emotional exhaustion, depersonalization, and personal accomplishment dimensions) were used in the study. T-tests, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis were used to analyze the influencing factors of psychological contracts and job burnout.Results:Among 361 respondents, there were 299 females (82.8%) and 62 males (17.2%), and a higher proportion of general practitioners (37.5%, 129/361) and nurses (41.8%, 151/361). The total score of psychological contracts among the 361 respondents was (141.6±19.5), with organizational responsibility scoring (70.6±11.2) and personal responsibility scoring (71.0±9.3). On the job burnout scale, emotional exhaustion scored (17.89±6.82), depersonalization scored (6.51±2.54), and personal accomplishment scored (30.95±5.70). General practitioners scored lower in organizational responsibility and personal responsibility compared to other members ( F=7.341,3.119, all P<0.05), and higher in emotional exhaustion and depersonalization ( F=7.637, 2.415, all P<0.05). Members with≤5 years of work experience scored lower in personal responsibility and personal accomplishment ( F=3.656, 4.205, all P<0.05). Correlation analysis showed that scores of organizational responsibility and personal responsibility were negatively correlated with levels of emotional exhaustion and depersonalization ( r=-0.618, -0.526, all P<0.01), ( r=-0.404, -0.393, all P<0.01), and positively correlated with personal accomplishment ( r=0.500, 0.558, all P<0.01). Multiple linear regression analysis indicated that organizational responsibility negatively affected emotional exhaustion and depersonalization ( β=-0.554, -0.274, all P<0.01), and positively affected personal accomplishment ( β=0.172, P<0.05). Personal responsibility positively affected personal accomplishment ( β=0.404, P<0.01). Conclusions:The study demonstrates that general practitioners in family doctor teams in Shenzhen city have lower psychological contract levels and are more prone to emotional exhaustion and depersonalization; members with≤5 years of work experience have lower personal responsibility and accomplishment. The results indicate that enhancing organizational responsibility can reduce job burnout of members in family doctor teams.
