Objective To investigate the health education needs and available resources in schistosomiasis-endemic areas based on integration of community resources, and to explore the operation pathways for health education and promotion during the stage of schistosomiasis elimination. Methods A community was selected from Nanji Township, Xinjian District, Nanchang City, Jiangxi Province around the Poyang Lake areas as the study site, and a questionnaire survey on health education needs for schistosomiasis control was conducted among permanent residents at ages of 20 years in the community during the period between June and July, 2022 using face-to-face interviews. In addition, the resources available for the community-based schistosomiasis control health education were investigated among workers in township-level specialized institutions, members of civil society organizations, villagers, teachers and high and primary school students through field observations, field surveys and thematic interviews. Results A total of 304 individuals participated in the questionnaire survey on community-based health education needs for schistosomiasis control, and 94.41% (287/304) and 93.42% (284/304) of the respondents were most interested in knowing/understanding knowledge of the morphology of schistosomes and knowledge associated with the transmission route of schistosomiasis. The four most popular patterns for disseminating schistosomiasis control knowledge included live broadcasting of schistosomiasis control videos (94.41%, 287/304), printed brochures (89.80%, 273/304), special lectures by doctors (62.50%, 190/304) and physical health education materials for schistosomiasis control (61.51%, 187/304). There were 96.71% (294/304) and 77.63% (236/304) of respondents that accepted the participation of township healthcare center and township government/village committees in dissemination of schistosomiasis control knowledge, and there were 95.72% (291/304) and 80.59% (245/304) of respondents that mainly acquired schistosomiasis control knowledge through village allocation of leaflets and volunteer schistosomiasis control activities, respectively. There was 96.71% (294/304) of respondents participating in the dissemination activities of schistosomiasis control knowledge held by village committees, township healthcare centers, and high and primary schools/kinder-gartens, and 61.25% (177/289) of respondents were willing to participate in volunteer schistosomiasis control activities. A total of 115 individuals participated in the survey of available resources for community-based schistosomiasis control health education, and there were a large number of organizational, human and cultural resources in the community that were useful for health communication services. Conclusions The abundant human and material resources from rural communities in schistosomiasis-endemic areas may be integrated into schistosomiasis control health education to generate a rural health education pathway with the joint participation of schistosomiasis control institutions, township governments, community departments and community residents, which may provide insights into the future development of schistosomiasis control health education.

Objective:To investigate the clinical efficacy of proximal gastrectomy and total gastrectomy in the treatment of Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospective cohort study was conducted. The clinicopathological data of 170 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to Guangdong Provincial People′s Hospital from January 2010 to December 2018 were collected. There were 125 males and 45 females, aged from 30 to 85 years, with a median age of 64 years. Of the 170 patients, 82 cases undergoing proximal gastrectomy were allocated into the proximal gastrectomy group and 88 cases undergoing total gastrectomy were allocated into the total gastrectomy group. Observation indica-tors: (1) surgical and postoperative situations; (2) follow-up and survival; (3) analysis of prognostic factors. Follow-up was conducted using telephone interview and outpatient examination to detect survival of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measure-ment data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan-Meier method was used to draw survival curves, and Log-Rank test was used for survival analysis. COX proportional hazard model was used for univariate and multivariate analyses. Variables with P<0.1 in univariate analysis were included for multivariate analysis. Results:(1) Surgical and postoperative situations. Cases with surgical approach as transthoracic or thoraco-abdominal approach, transabdominal approach, the operation time, cases with volume of intra-operative blood loss ≤100 mL or >100 mL, cases with length of proximal margin ≤1.5 cm or >1.5 cm, cases with radical surgery outcome as R 0, R 1, R 2, the number of lymph nodes harvest, cases with anastomotic leakage, cases with anastomotic stricture, cases with incision infection, cases with pleural infection or effusion, cases with abdominal infection or ascites were 61, 21, (211±18)minutes, 46, 36, 44, 38, 73, 6, 3, 15(9,22), 5, 2, 2, 4, 2 in the proximal gastrectomy group, respec-tively. The above indicators were 12, 76, (263±15)minutes, 27, 61, 45, 43, 82, 4, 2, 23(18,32), 4, 1, 3, 1, 4 in the total gastrectomy group, respectively. There were significant differences in the surgical approach, operation time, volume of intraoperative blood loss and the number of lymph nodes harvest between the two groups ( χ2=63.94, t=-25.50, χ2=11.19, Z=-5.62, P<0.05). There was no significant difference in the length of proximal margin or radical surgery outcome between the two groups ( χ2=0.11, Z=-0.95, P>0.05) and there was no significant difference in the anastomotic leakage, anastomotic stricture, incision infection, pleural infection or effusion, abdominal infection or ascites between the two groups ( P>0.05). (2) Follow-up and survival. All the 170 patients were followed up for 89(64,106)months. Of the 170 patients, the 5-year overall survival rates were 43.8% and 35.5% of the Siewert type Ⅱ and Ⅲ AEG patients, respectively, showing no significant difference between them ( χ2=0.87, P>0.05). Of the patients with Siewert type Ⅱ AEG, the 5-year overall survival rates were 41.7% and 54.3% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=1.05, P>0.05). Of the patients with Siewert type Ⅲ AEG, the 5-year overall survival rates were 31.3% and 37.5% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=0.33, P>0.05). The 5-year overall survival rates were 39.0% and 44.2% in the proximal gastrectomy group and the total gastrectomy group, respectively, showing no significant difference between the two groups ( χ2=0.63, P>0.05). Of the patients in TNM stage Ⅰ, stage Ⅱ, stage Ⅲ, the 5-year overall survival rates were 65.3%, 36.3%, 27.1% in the proximal gastrectomy group, versus 83.3%, 48.0%, 39.7% in the total gastrectomy group, showing no signifi-cant difference between the two groups ( χ2=0.02, 1.50, 1.21, P>0.05). (3) Analysis of prognostic factors. Results of univariate analysis showed that pathological N staging, degree of tumor differen-tiation and radical surgery outcome were related factors influencing prognosis of AEG patients ( hazard ratio=1.71, 1.70, 2.85, 95% confidence interval as 1.16-2.60, 1.15-2.50, 1.58-5.14, P<0.05). Results of multivariate analysis showed that pathological N staging and radical surgery outcome were independent factors influencing prognosis of AEG patients ( hazard ratio=1.55, 2.18, 95% confidence interval as 1.05-2.31, 1.18-4.02, P<0.05). Conclusions:There is no significant difference in the prognosis of Siewert type Ⅱ and Ⅲ AEG patients undergoing proximal gastrectomy or total gastrectomy. Proximal gastrectomy can be used for the treatment of advanced Siewert type Ⅱ and Ⅲ AEG.

A female patient who was admitted to the hospital on March 4, 2020 due to the right kidney mass for 4 days by physical examination. Ultrasound examination revealed a single space-occupying lesion in the right kidney, and further examination of the abdominal enhanced CT and three-dimensional reconstruction showed two lesions in the right kidney. The retroperitoneal laparoscopic partial nephrectomy was carried out. The pathological diagnosis were renal leiomyoma and renal eosinophiloma, respectively. After 1 year follow-up, no recurrence or metastasis was found.

A patient with intermittent right lumbar pain for more than one month and aggravating for one week was reported. The right laparoscopic radical nephrectomy was performed, and fibrosarcoma of the right kidney was diagnosed. The patient refused further radiotherapy or chemotherapy and was discharged on the 11th after surgery. One year after operation, the patient underwent chest CT, and subdural tumor of right lobe of liver was detected. A surgery was performed in another hospital, and liver metastasis from right renal fibrosarcoma was diagnosed. He was alive four months after operation.

The segmental testicular infarction rate is extremely low, usually showing acute testicular pain, which needs to be distinguished from testicular tumor, testicular torsion, etc. Only a few cases were reported. In this study, two cases were presented. Case one, a 13-year-old boy, was admitted to hospital due to right testicular swelling and pain for 3 days. Presenting with vomiting once on May 5, 2017.He underwent right scrotum exploration and testicular fixation. Testicular pain was disappeared and discharged on the five days operation. There was no obvious abnormality in color doppler ultrasound after one year after operation. Another patient, a 26-year-old man, was admitted to hospital due to left testicular swelling and pain for 6 on March 15, 2018. He was treated with Xue Saitong, natra heparin calcium and Maizhiling tablets. After seven days of treatment, the testicular pain improved and were discharged. One month after discharge, the patient had no pain or discomfort, and the color Doppler ultrasound showed that the left subtesticular polar-like low-isoecho, and a small amount of star-like blood flow signal around.
