Research on community-based rehabilitation exercise and physical activity and its benefits for people with mild and moderate disability in Shenzhen, Guangdong, China / 中国康复理论与实践

ObjectiveTo investigate the effect of community-based rehabilitation exercise and physical activity on the physical activity levels, functional states, and quality of life for people with mild and moderate disabilities in community settings, to ascertain the health benefits of their engagement in such fitness sports activities, anchoring in the WHO "Global Action Plan on Physical Activity 2018-2030: More Active People for a Healthier World" and the guidelines tailored for people with disabilities, using the theoretical framework and methodology of the International Classification of Functioning, Disability and Health (ICF). MethodsAligning with the WHO guidelines for people with disabilities and the ICF, a community-based rehabilitation exercise and physical activity program was designed for individuals with mild to moderate disabilities, featuring activities like fitness training (aerobic and resistance exercises), skill exercises (such as balance and coordination), as well as sports and recreational games (ball and games, etc.). A total of 230 people with mild and moderate disabilities were recruited from 20 communities in Shenzhen, with types of disabilities including physical, speech, intellectual, and mental. Professional rehabilitation fitness instructors implemented and supervised the program. The activities were of low to moderate intensity, 30 to 50 minutes per session, five times a month for six months. The community-based rehabilitation exercise and physical activity progress of these individuals was surveyed using the International Physical Activity Questionnaire (IPAQ), and their overall functioning was evaluated with WHODAS 2.0. The health-related quality of life was measured with WHOQOL-BREF. The health benefits from participation in community-based rehabilitation exercise and physical activity were assessed in terms of functioning, activity involvement, and quality of life. ResultsAfter the fitness activities, participation levels significantly increased in IPAQ domains of work-related, transport-related, domestic and gardening activity, and leisure time (|t| > 3.391, P < 0.001). The scores significantly decreased in the domains of cognition, activity, self-care, getting along, life activities and participation; and overall scores also decreased in WHODAS 2.0 (t > 6.639, P < 0.001). The scores significantly increased in the four dimensions of WHOQOL-BREF (|t| > 7.486, P < 0.001). ConclusionAfter participating in a six-month community-based rehabilitation exercise and physical activity program of mild to moderate intensity, individuals with mild to moderate disabilities have improved in physical activity and engagement levels, and the overall functioning and quality of life.

Effect of Passive Smoking on Antioxidant Capacity and Spermiogenesis of Testis and Epididymides in Rats / 环境与健康杂志

Objective To observe the adverse effects of passive smoking on antioxidant capacity and spermiogenesis of the testis and epididymides in rats.Methods SD rats were exposed to smoke in a self-made passive smoking chamber twice a day for 48 days.At the end of the experiment,the right testis and epididymides homogenate were prepared and the level of SOD,GSH-Px, NOS,NO and MDA were measured respectively.The sperms of left epididymides were observed by light microscope for determining sperm density,motility,progressive motility,fast progressive motility.The microstructure changes of left testis were observed.Results In passive smoking group,the level of MDA was significantly increased(P

Incidental renal cell carcinoma: analysis of 109 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To study the characteristics, diagnosis,treatment and prognosis of incidental renal cell carcinoma(RCC).</p><p><b>METHODS</b>109 cases of incidental RCC treated in 20 years were analyzed retrospectively and compared with 247 cases of non-incidental RCC.</p><p><b>RESULTS</b>The age, sex and side between incidental RCC and non-incidental RCC were not significant (P > 0.05). Compared to the non-incidental RCC,the diameter of incidental RCC [(4.1 +/- 1.7) cm] was smaller and its stage was lower (P < 0.01). Ultrasonography and CT can improve the detection rate of incidental RCC significantly, and operation is more effective for incidental RCC than for non-incidental RCC (P < 0.01). The 3 and 5 year cancer specific survival rates in patients with incidental RCC were higher than those of non-incidental RCC(P < 0.01). The detection rate of incidental RCC was higher from 1990 to 1999 (39.3%) than from 1980 to 1989 (15.6%) (P < 0.01).</p><p><b>CONCLUSIONS</b>Incidental RCC is not another type of RCC, but a developing stage of RCC without appearance of a symptoms. Ultrasonography and CT are important to diagnose incidental RCC. Low pathological stage, small size, early diagnosis, and radical nephrectomy indicate better prognosis of incidental RCC.</p>

Appearance of MRI in Tornwaldt′s cyst (report of 18 cases) / 中华放射学杂志

Objective To evaluate Tornwaldt′s cyst using MR imaging. Methods 1 452 cases with head MR imaging were reviewed. The signal intensity, shape, and size of the lesions were observed. Results Tornwaldt′s cyst were found in 18 of 1 452 cases (1 24%), all of the 18 cases were isointense to CSF on T 2WI and hyperintense to muscle on T 1WI.Tornwaldt′s cyst were round ( n =13)and ovoid ( n =5). The size of lesions were from 2 mm to 15 mm. There were 15 cases with adenoid hyperplasia. Conclusions Tornwaldt′s cysts occupied 1 24% in routine head MR imaging and were hyperintense to muscle on T 1WI and isointense to CSF ON T 2WI.
