ObjectiveTo understand the prevalence of tobacco use among residents aged 15 years old and above in Jiading District of Shanghai, and to provide a scientific basis for formulating effective regional tobacco control policies. MethodsThe Probability Proportional to Size (PPS) sampling method was employed to select one neighborhood committee (village) from each of Jiading District’s 11 subdistricts as survey monitoring sites. From the household registry of each selected neighborhood committee (village), 50 residential households were randomly sampled, resulting in a total of 550 households surveyed. Within each selected household, one permanent resident aged 15 years old or above was randomly chosen to complete the questionnaire. The content covered general information, exposure to secondhand smoke, awareness of tobacco related health hazards, etc. Statistical analyses were performed using SPSS 27.0 software. ResultsA total of 550 questionnaires were distributed, with 549 valid responses collected, and the effective response rate was 99.82%. The survey findings revealed that in 2023, the current smoking rate among individuals aged 15 years old and above in Jiading District of Shanghai was 18.76%, with males accounting for 38.93% and females accounting for 2.62%. Male gender was identified as a relative factor for smoking (OR=34.108, 95%CI: 14.440‒80.722), whereas higher education attainment emerged as a protective factor against smoking (OR=0.388, 95%CI: 0.184‒0.820). Among non-smokers aged 15 years old and above in Jiading District, the secondhand smoke exposure rate was 46.86%, with statistically significant differences observed across different age groups and occupations (P<0.001). Restaurants exhibited the highest secondhand smoke exposure rate of 42.14%, followed by households bearing (36.79%). The overall awareness rate among individuals aged 15 years old and above in Jiading District regarding four smoking-related diseases, namely stroke, heart disease, lung cancer, and impotence, was 48.45%, while the awareness rate for three secondhand smoke-induced diseases, namely adult heart disease, pediatric pulmonary disease, and adult lung cancer, was 64.29%. ConclusionThere is still room for reduction in the prevalence of tobacco use among individuals aged 15 yeas old and above in Jiading District. The exposure to secondhand smoke is severe, and residents have low awareness of the harm of tobacco. Tobacco control law enforcement should be strengthened, smoke-free-home health education should be included in tobacco control efforts, and targeted health education should be carried out.

ObjectiveTo investigate the application value of narrative medical model in communication with cancer patients with low education level. MethodsRetrospective analysis was performed on 80 cancer patients with low education level who were hospitalized in West China Hospital of Sichuan University from March 2019 to April 2020. They were randomly divided into control group （n=40） and observation group （n=40）. The control group received conventional nursing intervention， while the observation group received narrative medical nursing mode intervention. Both groups received intervention for 6 months. The Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS）， Morisky Medication Adherence Scale （MMAS-8）， Social Support Rating Scale （SSRS） and self-designed knowledge of the disease and cognition questionnaire were used for evaluation before and after intervention. ResultsAfter intervention， the SAS and SDS scores of observation group were lower than those of control group （t=7.493， 8.314， P<0.01）. After intervention， medication compliance of observation group was higher than that of control group （χ²=4.012， P=0.045）. SSRS subscale score and total score were higher than those in control group （t=2.198， 7.548， 2.664， 4.248， P<0.05 or 0.01）. After intervention， the mastery rate of knowledge about the disease and the excellent and good rate of cognitive behavior in observation group were higher than those in control group （χ²=4.588， 5.541， P<0.05）. ConclusionThe narrative medical model is of certain application value in communication with cancer patients with low education level. It can better improve the patients’ negative emotions， social support， and knowledge and cognition of the disease.

With the development of social economy and the transformation of modern medical models as the background, this paper expounds the importance of improving medical students' doctor-patient communication ability in terms of that doctor-patient communication can be helpful for doctors to deeply understand the illness, make accurate diagnosis, improve doctor-patient relationship, and reduce medical disputes. By analyzing the current situation and existing problems of doctor-patient communication teaching at home and abroad, the paper puts forward some suggestions on strengthening the training of medical students' doctor-patient communication ability from four aspects: cultivating professional communication skills, establishing multi-disciplinary teaching teams, adopting diversified teaching forms and formulating systematic evaluation system.

Objective To study the clinical effects of retroperitoneal laparoscopy renal cyst unroofing combined with percutaneous nephrolithotomy for patients with renal cyst complicated with upper renal or ureteral calculi. Methods 50 patients with renal cyst complicated with upper renal or ureteral calculi who were diagnosed and treated in our hospital from September 2012 to September 2014 were selected. They were equally assigned to two groups. 25 patients in the control group were given the treatment of open surgery, and 25 patients in the observation group were given the treat-ment of retroperitoneal laparoscopy renal cyst unroofing combined with percutaneous nephrolithotomy. Amount of bleeding during the surgery, surgery time, postoperative recovery time of gastrointestinal functions, postoperative hospi-talization time, postoperative exercise time, calculi clearance rate, relapse rate of calculi or cyst, incidence rate of complications, VAS and other indices between the two groups were compared. Results Amount of bleeding during surgery, surgery time, postoperative recovery time of gastrointestinal functions, postoperative hospitalization time, post-operative exercise time and VAS in the observation group were all significantly lower than those in the control group, (P<0.05); calculi clearance rate in the observation group was significantly higher than that in the control group (P<0.05);selected patients were re-examined after three months, and calculi relapse rate and cyst relapse rate in the observation group were both lower than those in the control group, but the differences were not statistically significant (P>0.05). Incidence rate of infections in the observation group was lower than that in the control group (P<0.05). Conclusion Retroperitoneal laparoscopy renal cyst unroofing combined with percutaneous nephrolithotomy for patients with renal cyst complicated with upper renal or ureteral calculi has various advantages of less trauma, less amount of bleeding during surgery, less pain after surgery, higher clearance rate of cyst and calculi and lower relapse rate, which is worthy of clinical promotion and application.
