Objective:To investigate the prevalence and related influencing factors of thyroid nodules in different occupational groups in Shijiazhuang City.Methods:Different occupational groups who underwent physical examination at the Second Hospital of Shijiazhuang City from May to December 2015 and had lived there for more than 10 years were selected as the investigation subjects, including workers, farmers, science and technology education personnel, medical and health personnel, civil servants and individual businessmen. Questionnaire survey and thyroid examination were conducted, blood lipid, blood glucose and thyroid hormone levels were tested, and related influencing factors of thyroid nodules were analyzed.Results:A total of 1 440 different occupational subjects were surveyed, and the prevalence of thyroid nodules was 20.35% (293/1 440). The prevalence of thyroid nodules in females (22.59%, 159/704) was significantly higher than that in males (18.21%, 134/736), and the difference was statistically significant (χ 2 = 4.26, P = 0.039). There was a statistically significant difference in the prevalence of thyroid nodules in different age groups (χ 2 = 73.87, P < 0.001), with the highest prevalence in the 70 - 80 age group (43.75%, 21/48). There was a statistically significant difference in the prevalence of thyroid nodules among different occupational groups (χ 2 = 36.56, P < 0.001), with the highest prevalence in individual businessmen (31.84%, 78/245). By univariate analysis, the prevalence of thyroid nodules in people with good economic status [27.45% (42/153) vs 19.48% (248/1 273)], radiation exposure history [26.39% (109/413) vs 17.92% (184/1 027)], and diabetes history [33.71% (30/89) vs 19.47% (263/1 351)] was higher (χ 2 = 5.35, 13.06, 10.45, P < 0.05). Conclusions:The prevalence of thyroid nodules in occupational group in Shijiazhuang City is relatively high, and the prevalence of thyroid nodules in females is significantly higher than that in males. Economic status, radiation exposure history and diabetes history are the main influencing factors.

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 develop a self-assessment scale of home volume management for patients with chronic heart failure(CHF),and to test its reliability and validity.Methods With the self-care theory as the theoretical framework,the initial scale was developed through literature analysis,qualitative interview and expert consultation.A questionnaire survey was conducted on 598 patients with CHF who were treated or reviewed in a tertiary hospital in Hangzhou from September 2022 to January 2023 to test the reliability and validity of the scale.Results The exploratory factor analysis extracted 4 common factors with the cumulative variance contribution rate of 61.268％.The results of confirmatory factor analysis showed that the main evaluation indicators were all within the acceptable range of the judgment standard.The item-level content validity index ranged from 0.853 to 1.000;the scale-level content validity index/average was 0.951.The Cronbach's a coefficient,half reliability and retest reliability of the overall scale were 0.930,0.723 and 0.867,respectively.Conclusion The self-rating scale of home volume management for CHF patients has good reliability and validity,and it can effectively assess the level of home volume management for CHF patients.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To explore the effect of ultra-early nursing intervention on postoperative cognitive behavior and prognosis of patients with cerebral hemorrhage.Methods:Using the convenient sampling method, a total of 82 patients with cerebral hemorrhage who were admitted to the First Affiliated Hospital of Zhengzhou University from March 2019 to January 2021 were selected as the research objects. According to the random number table method, they were divided into the control group and the observation group, with 41 cases in each group. Both groups received surgical treatment. The control group received routine nursing, while the observation group received ultra-early nursing intervention on the basis of routine nursing when vital signs were stable 48 hours after operation. The differences in neurological function (National Institutes of Health Stroke Scale, NIHSS) , cognitive function (Loewenstein Occupational Therapy Cognitive Assessment, LOTCA) and activity of daily living scores were compared between the two groups at 48 hours and 1 month after operation.Results:The NIHSS score at 1 month after surgery in both groups was lower than that at 48 hours after surgery and the NIHSS score at 1 month after surgery in observation group was lower than that in control group ( P<0.05) . The LOTCA dimension scores of the two groups at 1 month after operation were higher than those at 48 hours after operation and the LOTCA dimension scores of the observation group at 1 month after operation were higher than those of the control group ( P<0.05) . The activity of daily living scores of the two groups at 1 month after operation were higher than those at 48 hours after operation and the activity of daily living score of the observation group at 1 month after operation was higher than that of the control group , the differences were statistically significant ( P<0.05) . Conclusions:Ultra-early nursing intervention can effectively promote the recovery of postoperative neurological function and cognitive function in patients with cerebral hemorrhage and improve the activity of daily living of patients.

Objective:To investigate the influencing factors of goiter in school-age children aged 8 to 10 in non-high iodine areas of Shijiazhuang City.Methods:In April 2018, 9 non-high iodine counties (cities) were selected as monitoring sites in Shijiazhuang City, and capacity proportional probability sampling (PPS) method was used. Each monitoring site was divided into five sampling areas according to five orientations: east, west, south, north, and middle, one township was selected from each area, one elementary school was selected from each township, and 40 school-age children aged 8 to 10 (balanced age, half males and half females) were selected from each school as respondents. Urine samples from any one time of children and drinking water samples from their village were collected, and urinary iodine and water iodine were detected by arsenic cerium catalytic spectrophotometry; the thyroid volume of children was measured by B ultrasound method; at the same time, the height and weight of children were measured and the body mass index was calculated. The influencing factors of goiter were analyzed by logistic regression analysis.Results:A total of 1 867 urine samples of school-age children were collected, and the median urinary iodine was 190.65 μg/L, which was in the suitable level of iodine. A total of 1 046 drinking water samples were collected, water iodine ranged from 0.11 to 87.91 μg/L, and the median water iodine was 3.01 μg/L. A total of 1 867 school-age children were tested thyroid, the median thyroid volume was 3.01 ml. The medians thyroid volume of boys and girls (928 and 939 cases) were 2.90 and 3.13 ml, respectively, the difference was statistically significant between sex ( U = 2.09, P < 0.05); the medians thyroid volume of children aged 8, 9, and 10 years old (622, 629, 616 cases) were 2.47, 2.87, and 3.13 ml, respectively, the differences were statistically significant among ages ( H = 203.96, P < 0.01); the medians thyroid volume of normal, overweight and obese children (1 231, 300, 336 cases) were 2.61, 3.05 and 3.16 ml, respectively, the differences were statistically significant among body mass index ( H = 65.55, P < 0.01). The results of multifactorial logistic regression analysis showed that female and obesity were risk factors of goiter in school-age children [odds ratio ( OR) = 2.08, 2.86, 95% confidence interval ( CI): 1.05 - 4.12, 1.39 - 5.88, P < 0.05]. Conclusion:Female and obesity are risk factors of goiter in school-age children aged 8 to 10 in non-high iodine areas of Shijiazhuang City.
