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.

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.

Objective To investigate the impact of whole body vibration training combined with intermittent blood flow restriction on the motor function and community activity in elderly stroke patients with hemiplegia.Methods A total of 80 convalescent hemiplegic patients after stroke who were hospitalized in the Rehabilitation Medicine Department of Yichang Central People's Hospital(Xiling Campus)from October 2021 to December 2023 were included and randomly divided into control group(n=25),vibration group(n=28)and combination group(n=27)using the random number table method.All patients received conventional rehabilitation training,on the basis;the vabration group received whole body vibration training,while the combination group received whole body vibration training combined with intermittent blood flow restriction.Before and after 6 weeks of training,the balance function was evaluated with Berg balance scale(BBS),while the gait function was tested with 6-minute walking test(6MWT)and the Community Balance and Mobility scale(CB&M)was used to assess the community activity ability.The community balance and mobility(CB&M)were evaluated in the first and third month after discharge.Results There was no significant difference in BBS,CB&M scores and 6MWT walking distance between the three groups before training(P>0.05).After 6 weeks of training,the three groups showed significant increases in the BBS,CB&Mscores and the walk distance of 6MWT(P<0.001).Furthermore,compared with the control group,the combination group and the vibration group were significantly beter(P<0.05),and there was no signifi-cant difference between the combination group and the vibration group(P>0.05).At the first and third month of follw-up after discharge,the CB&M scores of the three groups were significantly higher than those of the control group(P<0.05),while there was no significant difference between the CB&M scores of the combination group and the vibration group at the first month of follow-up(P>0.05).But the CB&M scores of the combination group was higher than those of the vibration group at the third month of follow-up,and the difference was statistically signifi-cant(P<0.05).Conclusion On the basis of conventional rehabilitation,whole body vibration training combined with intermittent blood flow restriction can significantly enhance balance function,balance confidence,walking ability and mobility in early stage of community life for elderly stroke patients with hemiplegia,potentially facilitat-ing their return to community life.

Septic shock has always been a challenging problem for people,with a high incidence rate and mortality.After decades of development,significant progress has been made in the pathophysiology and clinical aspects of septic shock.The"Surviving Sepsis Campaign"guidelines provide a suitable approach to directing treatment,enabling earlier recognition of septic shock and reducing its mortality rate.However,there are still many challenges,such as refractory septic shock(RSS)and multiple organ failure.Over the past decade,extracorporeal membrane oxygenation(ECMO)technology has been increasingly applied in the treatment of critically ill patients.Whether ECMO can be considered as a salvage treatment for RSS is increasingly being considered.This report presents the experience of successfully treating a patient with RSS using ECMO in our department.For the management of RSS,it is recommended to consider ECMO as a worthwhile option,providing some practical experience for the treatment of RSS with ECMO.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To analyse the clinical application value of Lone-Star perineal exposure technique in performing abdominal perineal resection (APR).Methods:Conducted a retrospective review of 17 rectal cancer patients, including 13 males, 4 females, aged from 44 to 82 years old, with the average age of (67.6±9.7) years who underwent APR at Anqing Municipal Hospital from January 2020 to July 2024. The Lone-Star retractor-assisted (LSR) exposure method was employed for the perineal operation. After incising the skin and subcutaneous tissue, a Lone-Star retractor was utilized, with eight small hooks used to extend the incision in multiple directions, facilitating the release of deep tissues. The hooks were dynamically adjusted to optimize surgical field exposure.Results:All 17 patients were successfully underwent laparoscopic-assisted APR. Fifteen operations were independently performed by a single surgeon, while 2 required assistance for intraoperative arterial hemostasis. No perforations occurred, and all specimens had a negative circumferential resection margin (CRM). Postoperative complications were observed in 4 patients, including urinary retention in one, pulmonary infection in one, wound seroma in one, and stoma mucosal detachment in one, all of which were classified as Clavien-Dindo grade 3 or lower and cured.Conclusions:The LSR exposure technique may significantly improve perineal exposure during APR for rectal cancer. It could potentially enhance intraoperative safety and efficiency, and facilitate single-operator surgery.

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.
