Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.

Background and purpose:As one of the most fatal malignant tumors in China, the morbidity and mortality of lung cancer remain high. Early diagnosis and normative treatment is the key to improve the prognosis of lung cancer. The aim of this study was to explore the practice of early lung cancer screening with low-dose spiral computed tomography (CT) based on the current situation in community health service, with integration of superior resources of med-ical institutions at all levels in Shanghai.Methods:From Aug. 2013 to Aug. 2014, we screened high-risk population in selected communities of Minhang District, Shanghai, for early diagnosis of lung cancer with low-dose spiral CT combined with multidisciplinary comprehensive treatment models including minimally invasive surgery, exploring the medical service network covering prevention, diagnosis, treatment, rehabilitation and follow-up.Results:Screening population is 11 332 (male 7 144, female 4 188); Twenty-nine cases with pathological diagnosis of malignant tumor, including 27 cases of pri-mary lung cancer, 1 case of lung metastasis, 1 case of breast cancer. The morbidity of primary lung cancer is 238.26×10-5. There were 22 cases of Stage 0-Ⅰ lung cancer accounting for 81.48% of all diagnosed primary lung cancer.Conclusion:Based on community health service, screening with low-dose spiral CT could improve the early diagnosis rate of lung can-cer with feasibility and validity, which could be applicable in qualified eligible medical center and community in China.

【Objective】 To analyze the association between copper death-related genes and prognosis of prostate cancer and immune cell infiltration based on the cancer genome atlas (TCGA). 【Methods】 The mRNA transcriptome data of all prostate cancer patients were downloaded from TCGA, including 501 prostate cancer tissues and 52 normal tissues.The expression matrix of copper death-related genes was extracted with R software.Differential analysis and multivariate regression analysis were conducted to screen out the prognostic genes, which were then analyzed to explore the correlation between prognosis-related genes and immune cells. 【Results】 GCSH gene was significantly correlated with the prognosis of prostate cancer, and significantly correlated with dendritic cells, CD8⁺ T cells and plasma cells (P<0.05). 【Conclusion】 GCSH gene plays an important role in the occurrence and development of prostate cancer, and may become a prognostic marker of the disease.

OBJECTIVETo analyze the diseases and effects of the manipulations to promoteby filiform needles, with the help of data mining technique.

METHODSLiterature about different manipulations to promoteby filiform needles in recent 60 years was collected in China National Knowledge Infrastructure(CNKI). Then databases were established to mine the relativities among the diseases, subjects, acupoints selection law,routes and directions of meridianand effects.

RESULTS①Total 489 articles were included. The basic manipulations with the frequency of 630 were on the top. The auxiliary and four methods ofrespectively appeared 70 times. The diseases in the internal medicine were treated with the basic and auxiliary methods of the higher frequencies, 311 and 44 times separately. While the four methods ofwere mostly used in the surgical area, 37 timestotally. ②The diseases treated from high to low by lifting, thrusting and twirling represented retention of urine, sequelae of stroke, pain in waist and lower limbs, of which the effect for retention of urine was better than those of the other two, and the lifting and thrusting method was superior to twirling. ③As for the auxiliary methods, 25 times were found about vibration needling; 18 times, twisting. The highest frequency of 6 times for the vibration needling was on the sequelae of stroke; while 4 times for the twisting, stranguria. ④As to the four methods of,was most frequently applied, and its highest frequency of 18 was onsyndrome.

CONCLUSIONSManipulations to promoteby filiform needles are crucial to achieving the effects of acupuncture. The basic methods are widely used in clinic and have been seen good efficacy. While the auxiliary means assist to promoteto stimulate the body,among which the four methods ofare mainly to smooth the meridians and driveof patients with surgical diseases and take meridian blocking the priority.
