ObjectiveTo investigate the status of tooth loss in people aged 50 and above, so as to understand their oral health status and provide scientific evidences for promoting oral health of middle-aged and elderly people. MethodsA total of 400 patients who visited the department of stomatology at Sijing Hospital in Songjiang District of Shanghai were performed oral health examinations and their information was collected according to the national epidemiological survey standards for oral health. ResultsThere were statistically significant differences in tooth loss among people aged 50 and above with different ages, educational levels, occupations, types of medical insurance and chronic diseases (P<0.05), but gender and monthly income had no statistically significant correlations with tooth loss (P>0.05). Among lifestyle factors, smoking, alcohol consumption and tea drinking had no statistically significant impacts on the number of remaining teeth (P>0.05), but toothbrushing frequency, flossing frequency, toothpick use frequency, toothbrush replacement frequency, and tooth loosening were statistically associated with the number of remaining teeth (P<0.05). Multiple linear regression analyses indicated that a total of 7 related factors including age, educational level, occupation, medical payment type, chronic disease, tooth loosening and toothpick use frequency were significantly associated with the number level of remaining teeth in individuals aged 50 and above. ConclusionAge, chronic disease, and tooth loosening were influencing factors affecting the number of teeth left in people aged 50 and above. It is recommended to strengthen oral health education and improve healthcare awareness to reduce the risk of tooth loss in people aged 50 and above.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture combined with levodopa in the treatment of Parkinson's disease（PD）. MethodsA total of 60 patients with PD were enrolled and randomly assigned to test group or control group， with 30 patients in each group. The control group received levodopa only， starting at 100 mg per dose， three times daily， with gradual increases not exceeding a maximum daily dose of 800 mg. The test group received acupuncture three times per week in addition to levodopa. Both groups were treated for 12 weeks. Assessments were conducted before treatment， after 6 and 12 weeks treatment， using the Unified Parkinson's Disease Rating Scale（UPDRS）， Wearing-Off Questionnaire-9（WOQ-9）， Montreal Cognitive Assessment（MoCA）， Mini-Mental State Examination（MMSE）， Depression Rating Scale（DRS）， Hamilton Depression Scale（HAMD）， Hamilton Anxiety Scale（HAMA）， PD Questionnaire-39（PDQ-39）， and Pittsburgh Sleep Quality Index（PSQI）. Repeated measures ANOVA was utilized to evaluate the effects of time， group， and their interaction on each index. Spearman correlation analysis was conducted to examine the relationships between combined treatment and outcome scores. Adverse events in both groups were recorded throughout the study. ResultsBoth groups showed significant improvements after 6 and 12 weeks treatment， with decreases in UPDRS total score， WOQ-9 total score， DRS score， HAMD score， HAMA score， PDQ-39 score， and PSQI score， and increases in MoCA and MMSE scores（P＜0.05）. Compared with the control group， the test group demonstrated significantly greater improvements in all the above indicators after 6 and 12 weeks （P＜0.05）. Repeated measures ANOVA showed significant time main effects， group main effects， and their interaction across all outcome measures（P＜0.01）. Spearman correlation analysis revealed that combined therapy was significantly negatively correlated with UPDRS， WOQ-9， DRS， HAMD， HAMA， PDQ-39， and PSQI scores， while positively correlated with MoCA and MMSE scores after 12 weeks of treatment（P＜0.05）. Both groups did not experience any serious adverse events and did not affect treatment. ConclusionAcupuncture combined with levodopa is more effective than levodopa alone in improving motor function， non-motor symptoms， cognitive function， depression and anxiety， quality of life， and sleep quality in patients with PD， with good safety.

Objective: To understand the indoor light at night (LAN) exposure intensity during sleep among children and adolescents in Shanghai, so as to provide a basis for exploring potential health risks and formulating effective interventions. Methods: From April to December in 2024, a total of 628 students in grades 4-7 were recruited from three schools in Shanghai. A portable illuminance meter was used to measure LAN for one week, and participants recorded their sleep time. The Kruskal-Wallis H- test was used for comparison between groups, and the error bar chart was used to show the trend and variation range of average LAN exposure intensity in different sleep periods. Results: The indoor LAN exposure intensity of children and adolescents in Shanghai was [2.4(0.8, 5.9)lx] during sleep, and 28.8% of children and adolescents were exposed to indoor LAN≥5 lx. There was no significant differences in indoor LAN exposure intensity between boys [2.4(1.0, 5.9)lx] and girls [2.3(0.7, 5.9)lx] ( Z=-0.86, P > 0.05 ). The indoor LAN exposure intensity of primary school students [2.9(1.1, 6.6)lx] was higher than that of junior high school students [1.0(0.3, 3.1)lx] ( Z =-5.87), and indoor LAN exposure intensity of students in the main urban area [3.2(1.1, 7.8)lx] was higher than that of rural students [1.6(0.5, 4.3)lx] ( Z =-5.23)(both P <0.05). The indoor LAN exposure intensity showed an overall decreasing trend during sleep of children and adolescents ( tau=-0.81, P =0.02), with a slight increase before waking up. Conclusions Indoor LAN exposure intensity among children and adolescents in Shanghai is generally high, especially among primary school students and students living in the main urban area. Health policy and education should be strengthened to reduce the impact of LAN on children and adolescent health.

ObjectiveTo analyze the incidence and epidemiological characteristics of infectious diseases among the primary and secondary school students in Songjiang District, Shanghai, and to provide a scientific basis for the prevention and control of infectious diseases in schools. MethodsDescriptive epidemiological methods were used to analyze the types and numbers of infectious diseases among students in Songjiang District from 2018 to 2022. Furthermore, the incidence, constituent ratios and incidence precedence of infectious diseases were calculated simultaneously. ResultsA total of 5 543 cases of student infectious diseases were reported in Songjiang District from 2018 to 2022, involving 17 types of infectious diseases, with an annual incidence rate of 11.38‰. The reported infectious diseases were mainly respiratory infectious diseases (77.72%), followed by intestinal infections (21.88%). Chickenpox, influenza, and hand-foot-mouth disease were the top three infectious diseases according to the incidence rate, with a total of 3 966 cases reported, accounting for 71.55% of the total cases. More male cases were reported than females with a gender ratio of 1.44∶1. Infectious diseases were most prevalent among students aged between 6~<13 years (4 383 cases, accounting for 79.07%). The distribution of infectious diseases among students showed two peaks: from November to December and April to May. Jiuting Town, Xinqiao Town, and Chedun Town were the top three subdistricts (towns) in terms of incidence rate. ConclusionThe situation of infectious disease prevention and control among the primary and secondary school students in Songjiang District is severe, and monitoring and prevention of infectious diseases among students should be strengthened, especially respiratory infectious diseases.

The results of the circular distribution method showed that the peak day of scarlet fever from March to August was May 12, and the epidemic peak period was from April 3 to June 20. From September to February of the next year, the peak day of scarlet fever was December 21, and the epidemic peak period was from December 2 to January 9 of the next year. The differences were all statistically significant (P values were all less than 0.05). Conclusion The peaks of scarlet fever in Songjiang District mainly occur in May and December. It is suggested that the monitoring methods and prevention strategies should be adjusted in time according to Seasonal characteristics of scarlet fever.

Objective To evaluate the clinical curative effect of CT-guided dorsal root ganglion pulsed radiofrequency(DRG-PRF)combined with ozone injection in treating patients with chronic postherpetic neuralgia(PHN).Methods A total of 300 patients with chronic PHN,who were admitted to the Hengshui Municipal People's Hospital of China from December 2020 to August 2023,were enrolled in this study.Using random digital table method,the patients were divided into observation group(n=150,receiving ozone injection+CT-guided DRG-PRF)and control group(n=150,receiving ozone injection alone).The curative effect,infrared thermal imaging index(skin temperature difference between skin lesion area and the corresponding healthy side,i.e.ΔT),sleep quality,pain degree(determined by numerical rating scale,NRS),and pain/inflammatory factors including prostaglandin E2(PGE2),substance P(SP),interleukin-6(IL-6),interleukin-1β(IL-1β)were compared between the two groups.Results The total response rate in the observation group was 92.67％(139/150),which was higher than 83.33％(125/150)in the control group,the difference was statistically significant(P＜0.05).At one d,3 d,7 d,one month and 3 months after treatment,the scores of ΔT,PSQI and NRS in the observation group were lower than those in the control group,and the differences were statistically significant(all P＜0.05).The levels of serum PGE2,SP,IL-6 and IL-1β in the observation group were lower than those in the control group,and the differences were statistically significant(all P＜0.05).Conclusion For the treatment of chronic PHN,CT-guided DRG-PRF combined with ozone injection has reliable clinical effect,it can effectively promote the recovery of skin damage,improve sleep quality,relieve pain,and regulate the levels of pain and inflammatory factors.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.
