Background::Psychological stress has been reported to be a potential risk factor for hypertension among females, but it remains unclear whether spousal chronic stress levels alter the risk of hypertension among women. We examined the associations between stress within the family and hypertension among married women.Methods::Reproductive-aged women who were planning for pregnancy and their husbands were recruited from the National Free Pre-pregnancy Checkup Projects (NFPCP) across 31 provinces in China in 2016 and 2017. Perceived stress of wives or husbands was measured with a 5-point Likert-type scale, and assessed from three domains: work/life-related stress, economic stress, and overall stress. Multivariable-adjusted logistic regression models were used to assess the associations between stress status and the prevalence of hypertension.Results::Of 10,027,644 couples, 261,098 (2.60%) women had hypertension. The results showed that higher stress levels among themselves or their husbands were associated with a higher prevalence of hypertension in women ( Pfor trend <0.001). Compared with non-stressed participants, female participants with the highest stress themselves were at a greater risk of hypertension, with adjusted odds ratio (OR) of 1.31 (95% confidence interval [CI]: 1.25-1.37); and compared with participants whose husbands had no stress, those whose husbands had the highest stress level were at a higher risk of hypertension with adjusted OR of 1.24 (95% CI: 1.20-1.29). Moreover, compared with non-stressed status for both couples, only-wife-stressed, only-husband-stressed, and both-stressed couples were found to be significantly associated with increased risks of wives’ hypertension, with adjusted ORs of 1.28 (95% CI: 1.25-1.31), 1.19 (95% CI: 1.17-1.21), and 1.28 (95% CI: 1.26-1.31), respectively. Conclusion::Moderate to severe stress in both spouses might be associated with female hypertension prevalence, which highlights the importance of paying attention to the psychological stresses of couples within the family.

Objective:To investigate the clinical characteristics, diagnosis, treatment, and prognosis of primary thyroid lymphoma (PTL) .Methods:A retrospective analysis was conducted on the clinical and pathological data of 34 newly diagnosed PTL patients admitted to Beijing Tongren Hospital from September 2010 to February 2023. The Kaplan-Meier survival curve and Log-rank test were used for survival analysis, and the Cox regression model was applied for univariate analysis of prognostic factors.Results:All 34 PTL patients presented with cervical mass as the initial clinical manifestation. There were 9 males and 25 females. The pathological diagnosis was diffuse large B-cell lymphoma (DLBCL) in 29 patients and mucosa-associated lymphoid tissue (MALT) lymphoma in 5 patients. Among the DLBCL patients, 6 had B symptoms, 17 had an Eastern Cooperative Oncology Group (ECOG) score of ≥2, the Ann Arbor staging was stage Ⅰ-Ⅱ in 21 cases and stage Ⅲ-Ⅳ in 8 cases, the tumor diameter was ≥10 cm in 4 cases, and 14 had concurrent Hashimoto thyroiditis; 27 cases received chemotherapy, with 21 cases achieving complete remission (CR), 2 cases partial remission (PR), and 6 cases of disease progression; the 5-year progression-free survival and overall survival rates were 78.9% and 77.4%, respectively; univariate survival analysis showed that B symptoms, tumor diameter ≥10 cm, and Ann Arbor stage Ⅲ-Ⅳ were significant factors affecting patient prognosis ( P<0.05). MALT lymphoma patients were all in stages Ⅰ-Ⅱ, had an ECOG score of 0-1, and were without B symptoms. All patients underwent surgical resection, with 4 cases achieving CR and 1 case PR. Conclusion:PTL is more common in females with concurrent Hashimoto thyroiditis, with the majority of pathological types being B-cell lymphoma. The main treatment is chemotherapy, supplemented by radiotherapy and surgery, and the prognosis is relatively favorable.

Objective:To investigate the risk factors for intraoperative hemorrhage during endoscopic submucosal dissection (ESD) for colorectal lesions.Methods:Data of 386 patients with colorectal lesions, who underwent ESD at The Third People's Hospital of Datong and its cooperative hospital, Nanjing Drum Tower Hospital, from December 2019 to August 2021 were retrospectively analyzed. The patients were divided into the hemorrhage group ( n=85) and the non-hemorrhage group ( n=301) according to intraoperative hemorrhage. The correlationship of patients'basic information, lesion-related factors and hemorrhage during colorectal ESD was analyzed. Univariate and multivariate logistic regression were used to identify the risk factors for intraoperative hemorrhage during ESD. The risk predictive model of intraoperative hemorrhage during ESD was established according to the screened risk factors, and receiver operator characteristic (ROC) curve was used to evaluate the predictive model. Results:Univariate logistic regression showed that a history of diabetes ( OR=2.340, P<0.05), a history of coronary atherosclerotic heart diseases ( OR=3.100, P<0.05), the lesion located in the rectum ( OR=3.272, P<0.05), longer lesion ( OR=1.093, P<0.05), wider lesion ( OR=1.057, P<0.05), larger lesion ( OR=1.126, P<0.05), depressed lesion ( OR=6.128, P<0.05), the laterally spreading lesion ( OR=2.651, P<0.05), the lesion infiltrated into the SM-S layer ( OR=0.088, P<0.05), the lesion infiltrated into the SM-D layer ( OR=0.174, P<0.05), the diameter of hemorrhage vessels 0.5~<1.0 times of the diameter of incision knife ( OR=246.854, P<0.05), the postoperative pathology as early cancer ( OR=7.000, P<0.05) were risk factors for intraoperative hemorrhage during ESD. Considering the quantitative relationship between the length, the width and the area of lesions, multi-factor models were constructed using the length and area of lesions respectively. Forward stepwise regression was used to screen variables and determine the final model, and the results showed that a history of coronary atherosclerotic heart diseases, the depressed lesion, the longer lesion, the larger lesion, the diameter of hemorrhage vessels 0.5~<1.0 times of the diameter of the incision knife were independent risk factors for intraoperative hemorrhage during ESD. The two modeling results of the lesion length and the lesion area were very similar. Therefore, lesion length was recommended to describe lesions in clinical practice. Conclusion:A history of coronary atherosclerotic heart disease, the depressed lesion, the longer lesion, the larger lesion, the diameter of vessels 0.5~<1.0 times of that of the incision knife are independent risk factors for intraoperative hemorrhage during ESD.

Objective:To describe the characteristics of molecular transmission network of newly diagnosed HIV-1 infected patients, analyze their risk factors related to network access and provide a scientific basis for precise prevention of HIV infection.Methods:For 340 blood samples collected from confirmed HIV-1 infection cases aged ≥50 years in Pengzhou city of Sichuan province from April 2019 to August 2021, nested PCR amplification was used to amplify, clean up and splice clips the pol gene region. The phylogenetic tree was constructed by multi-sequence comparison to distinguish subtypes, and the pairwise genetic distance was calculated. When the genetic distance threshold was 0.90%, the number of clusters was the largest (41), and the molecular transmission network was constructed.The χ2 test and logistic regression analysis were performed.The software SPSS 19.0 was used for statistical analysis. Results:A total of 340 samples were successfully amplified (97.06%, 330/340) in 330 samples. 6 HIV-1 subtypes identified, including:CRF01_AE(56.67%,187/330), CRF07_BC(27.88%,92/330), B(11.21%,37/330), CRF08_BC(3.33%,11/330), CRF55_01B(0.61%,2/330) and C(0.30%,1/330).The network entry rate was 58.79% (194/330).The results of logistic regression analysis of the risk factors of HIV-1 molecular transmission network in the research subjects showed that compared with illiteracy, junior high school ( OR=0.35, 95% CI:0.13-0.97) and high school/technical secondary school ( OR=0.14, 95% CI: 0.02-0.97) had lower possibility of network entry. Compared with farmers, unknown occupations ( OR=0.40,95% CI: 0.17-0.95) are less likely to enter the network .Compared with CRF01_AE, CRF07_BC ( OR=0.20, 95% CI: 0.11-0.35) and CRF08_BC subtype ( OR=0.09, 95% CI: 0.02-0.45) were less likely to enter the network. Conclusions:The sources of AIDS transmission among middle-aged and elderly people of rural areas are diversified in Pengzhou city of Sichuan province. AIDS intervention should focus on middle-aged and elderly farmers with low educational level, and strengthen detection and traceability investigation.

Gastric bronchogenic cysts （GBCs） is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore , postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs：ultrasound-guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra-cavity growth pattern. However , GBCs with extra-cavity growth pattern is featured with deeply anatomical position , large size , and prone on attaching to vital blood vessels and organs , which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature , in order to provide references for clinical diagnosis of GBCs.

Objective: To investigate effects of functional training on physical and cognitive function in 4-5 years old children, so as to provide a reference for the research on development of children s physical and cognitive functions. Methods: The 173 participants aged 4-5 were enrolled from 6 kindergartens in Xicheng District, Beijing and were divided into experimental (n=94) and control groups (n=79) by randomized digital tables. The experimental group were asked to receive a 18 week special designed functional movement training, which were not performed to the control group. The two groups were tested with physical and cognitive assessments before and after the intervention, and the results were compared pre/post in individual group and between groups with t tests. Results: Compared with control group, the score of standing long jump among children in the experimental group was improved by 5.72%, and that of feet jump was improved by 23.79%, that of 10-meter-shuttle run was improved by 13.95%, that of simple reaction was by 20.34%, and that of attention was by 18.96%, and all the improvement was of statistical significance(t=-2.75, 6.68, 10.79, 5.07, 4.32, P<0.01). Conclusion Both physical and cognitive functions were enhanced by the functional physical training in 4-5 year-old children.

【Objective】 To investigate and analyze the current situation of the human resources as well as blood collection and supply of blood banks of Zhejiang Province, so as to understand the problems existing in the development of human resources and put forward suggestions. 【Methods】 Questionnaires were issued to Blood Center of Zhejiang Province, municipal central blood stations, and county-level central blood banks to investigate the relevant data in 2015 and 2019. Meanwhile, some data were obtained through the Zhejiang Blood Management Information System (BIS3.0), symposiums, and querying medical service data. Statistical analysis was carried out. 【Results】 Among the 28 blood banks, filled the questionnaires, 927 personnel were in accordance with the authorized strength, accounting for 62.26% (927/1 489), and 1069 health technicians, accounting for 71.519% (1 060/1 489). From 2015 to 2019, the annual growth rate of human resources in blood banks was 2.02%, lower than the annual growth rate of whole blood collection volume 4.83% and the annual growth rate of clinical blood supply (red blood cell) 4.82%, lagging behind the annual growth rate of 6.55%, 8.71% and 12.36% in the number of diagnoses, inpatients and surgeries in the hospitals across the province. The average annual growth rate of doctors and nurses in blood banks was 0.17% and 1.67%, lower than that of licebsed doctors and registered nurses of the province, which was 6.78% and 8.27%, respectively. 【Conclusion】 With the development trend of blood collection and supply, the personnel allocation and the proportion of health technicians of blood banks across Zhejiang Province is insufficient. It is suggested to establish a manpower allocation standard suitable to the business volume, give priority to properly solvement of the current employment, strengthen training, and improve the efficiency of physical examination consultation, testing and phlebotomy positions.
