In the context of exploring the specialization of medical social work， this paper explored the current situation， problems， and future development directions of medical social work supervision based on the perspective of four basic systems of social work practice. It has ethical significance and professional value for improving the professional ability and service quality of medical social workers. Currently， medical social work supervision is developing at a slow pace， while its overall construction remains behind. Taking the Beijing municipal medical social work supervision project as a case study， from the specific to the general， it was found that there were practical dilemmas in medical social work supervision， such as the lack of system， standards， and talents. Based on these， suggestions for improvement were proposed by focusing on the change of promoter system， action system， and goal system.

Objective:To study the infection and epidemiological characteristics of soil borne nematode disease in Sihong County, Suqian City, and to provide scientific basis for further development of prevention and control measures.Methods:In 2022, according to geographic location, Sihong County was divided into east and west areas. Jieji Town, Shiji Township, and Linhuai Town were selected from the east area, and Tianganghu Township, Meihua Town from the west area. One administrative village was selected as a survey point in each township. Using cluster sampling method, 450 permanent residents aged 3 years old and older in the village were selected as the respondents for questionnaire survey and fecal sample collection. The infection status of hookworms, roundworms, whipworms and pinworms in fecal samples were examined, transparent tape anal swab method for detecting pinworm eggs in children, and influencing factors were analyzed.Results:A total of 2 264 survey subjects were included, 18 cases of soil borne nematodes were detected as positive, with an overall positive rate of 0.80%. Among them, 15 cases were positive for hookworms, 1 case was positive for whipworms, and 2 cases were positive for pinworms, with detection rates of 0.66%, 0.04%, and 0.09%, respectively. No ascaris lumbricoides were detected. Transparent tape anal swab method was used to examine 142 children, and the positivity rate of 1.41% (2/142). By township, the detection rate of soil borne nematodes was the highest in Jieji Town, at 2.41% (11/457); the others were Meihua Town, Tianganghu Township, Shiji Township, and Linhuai Town, with detection rates of 0.89% (4/451),0.66% (3/454), 0 (0/451) and 0 (0/451), respectively. There was a statistically significant difference between different townships (χ 2 = 19.21, P < 0.001). Among the 18 positive cases of soil borne nematode, 7 were males and 11 were females, with detection rates of 0.66% (7/1 063) and 0.92% (11/1 201), respectively, the difference was not statistically significant (χ 2 = 0.47, P = 0.491). The age distribution showed the highest detection rate in the 40 - < 60 age group, at 1.42% (9/634), with statistically significant differences between different age groups (χ 2 = 6.41, P = 0.033). The occupational distribution showed the highest detection rate in farmers, at 1.46% (9/617), with statistically significant differences between different professions (χ 2 = 8.00, P = 0.034). The differences in total soil borne nematode and hookworm detection rates were statistically significant among different methods of treating human and animal feces (χ 2 = 11.01, 9.02, P = 0.003, 0.011). Conclusions:The main species of soil borne nematode infections in Sihong County, Suqian City are hookworms, with fewer infections of whipworms and pinworms, and no roundworm infections observed. There are regional differences in detection rate. In the future, it is necessary to strengthen health education for key populations, enhance health knowledge publicity, and effectively intervene to change unhealthy production and lifestyle, further reducing the infection of soil borne nematodes in Suqian City.

ObjectiveTo explore the effect of nutrition combined with exercise intervention on stroke patients with sarcopenia. MethodsFrom January to June, 2022, 60 stroke patients with sarcopenia were randomly divided into control group (n = 15), nutrition group (n = 15), exercise group (n = 15) and combined group (n = 15). All the groups received routine rehabilitation training, while the nutrition group received nutrition intervention, the exercise group received exercise intervention, and the combined group received both the nutrition and exercise intervention, for four weeks. Before and after intervention, the muscle index was measured with bioelectrical impedance analysis, gripping strength of the healthy and the affected side was measured with gripping strength meter, and the patients were assessed with modified Barthel Index (MBI) and Berg Balance Scale (BBS). ResultsFour cases in the control group, two in the nutrition group, one in the exercise group, and three in the combined group dropped down. The muscle index, gripping strength, and the scores of MBI and BBS improved in all the groups after intervention (|t| > 3.004, P < 0.05), while all improved more in the combined group than in the other three groups (P < 0.05), and the grip strength of the healthy side was more in the exercise group than in the nutrition group (P < 0.05). ConclusionNutrition or exercise intervention alone can improve the muscle quality, grip strength, activities of daily living and balance of stroke patients with sarcopenia, while the combination is more effective.
