Objective To systematically evaluate the risk prediction models for anastomotic leakage (AL) in patients with esophageal cancer after surgery. Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

Objective To investigate the clinical effect of superficial temporal artery-middle cerebral artery anastomosis(STA-MCA)in the treatment of patients with occlusive cerebrovascular disease.Methods A total of 74 patients with occlusive cerebrovascular disease admitted to our hospital were included and divided into the observation group and control group according to the random number table method,with 37 cases in each group.Patients in the control group received conservative treatment,and patients in the observation group received STA-MCA.After 3 months of follow-up,the cerebral blood flow indexes(including cerebral blood flow of anterior cerebral artery,and peak time)before treatment and 3rd day,1st month and 3rd month after treatment were observed,the modified Rankin scores before treatment and 3rd day and 1 month after treatment were recorded,and the revascularization and occurrence of complications after treatment were recorded.Results At 1 month and 3 months after treatment,the cerebral blood flow of anterior cerebral artery in the two groups increased and the peak time was shortened,and the cerebral blood flow of anterior cerebral artery in the observation group was higher than that in the control group,and the peak time was shorter than that in the control group,with statistically significant differences(P<0.05).The modified Rankin scores of the two groups 1 month after treatment were lower compared with those before treatment,and the modified Rankin score of the observation group was lower than that of the control group,with statistically significant differences(P<0.05).At 1 month after treatment,the proportions of patients with grades 0 and 1 of vascular reconstruction in the observation group were lower than those in the control group,and the proportions of patients with grades 2 and 3 were higher than those in the control group,with statistical significant differences(P<0.05).At 3 months after treatment,the proportions of patients with grades 0 and 1 of vascular reconstruction in the observation group were lower than those in the control group,and the proportion of patients with grade 3 of vascular reconstruction was higher than that in the control group,with statistically significant differences(P<0.05).There was no statistically significant difference in the total incidence of complications after treatment between the two groups(P>0.05).Conclusion STA-MCA has a good clinical effect in the treatment of patients with occlusive cerebrovascular disease,which is conducive to improving the cerebral blood flow indexes and promoting the recovery of neurological function and vascular reconstruction,with safety and reliability.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

Objective:To explore the dosimetry difference between intensity-modulated radiotherapy (IMRT) and volumetric intensity modulated arc therapy (VMAT) based on the inner edge tangent field (IETF) after left-sided breast conserving surgery.Methods:The localization CT and target organ at risk (OAR) data of 35 patients with left-sided breast cancer treated with IMRT after breast conserving surgery at Department of Radiotherapy in Yunnan Cancer Hospital from June 2022 to June 2023 were selected. The IETF-IMRT and the IETF-VMAT plans were designed for the same patient based on IETF, the dosimetry differences of target areas and OAR, as well as the planned execution time were compared between the two groups.Results:Dosimetry of target areas: for IETF-IMRT and IETF-VMAT, the D 98% of the planning target volume were (47.92±0.51) and (48.21±0.33) Gy, respectively, while the D 50% were (52.04±0.22) and (51.91±0.26) Gy, respectively, and the D 2% were (53.93±0.36) and (53.62±0.41) Gy, respectively, the conformity index were 0.84±0.03 and 0.87±0.02, respectively, while the homogeneity index were 0.12±0.01 and 0.10±0.01, respectively, with statistically significant differences ( t=-3.87, P<0.001; t=3.53, P=0.001; t=5.30, P<0.001; t=-13.60, P<0.001; t=6.24, P<0.001). Dosimetry of OAR: for IETF-IMRT and IETF-VMAT, the left lung V 5 were (31.91±6.28) % and (33.99±6.31) %, respectively, and the V 20 were (11.71±2.06) % and (9.73±2.12) %, respectively, with statistically significant differences ( t=-4.18, P<0.001; t=12.40, P<0.001). The right lung V 5 were (0.11±0.08) % and (7.13±3.12) %, respectively, and the D mean were (1.05±0.12) and (2.71±0.27) Gy, respectively, with statistically significant differences ( t=-33.62, P<0.001; t=-13.30, P<0.001). The spinal cord D 2% were (1.08±0.11) and (4.83±1.40) Gy, respectively, with a statistically significant difference ( t=-15.99, P<0.001). The left lung D mean were (7.45±1.08) and (7.37±1.03) Gy, the heart D mean were (4.21±0.96) and (4.41±0.48) Gy, and the right-sided breast D mean were (3.74±1.52) and (3.48±1.11) Gy, respectively, with no statistically significant difference ( t=1.16, P=0.253; t=-1.76, P=0.088; t=1.41, P=0.169). Planned execution time: the execution time of IETF-IMRT and IETF-VMAT was (10.73±1.21) and (2.18±0.17) min, respectively, with a statistically significant difference ( t=44.71, P<0.001) . Conclusion:Both IETF-IMRT and IETF-VMAT can meet clinical requirements, however the two techniques have their own characteristics. IETF-VMAT has better conformity and homogeneity of target region. The planned OAR dosimetry in both plans are significantly lower than the dose limit of postoperative radiotherapy for breast cancer, among which the left lung V 5, the right lung V 5, D mean and spinal cord D 2% of IETF-IMRT are slightly lower, the left lung V 20 of IETF-VMAT is slightly lower. IETF-VMAT significantly reduces the planned execution time compared with IETF-IMRT, thus can greatly reduce the dose deviation caused by patient position change, and significantly improve patients experience and comfort of radiotherapy. Taken together, IETF-VMAT has advantages over IETF-IMRT in radiotherapy after breast conserving surgery of left-sided breast cancer.

Objective:To assess the feasibility of using the posterosuperior tetralogy (PS-Tetra) score for predicting the prognosis of repair of posterosuperior massive rotator cuff tears.Methods:Data were retrospectively reviewed for patients who underwent repair of posterosuperior massive rotator cuff tears from February 2016 to June 2020. A total of 95 (male 48, female 47) shoulders with an average age of 58.52±8.33 years (range, 27-76 years) were included. The American Shoulder and Elbow Surgeons (ASES) scores and shoulder range of motions (ROM) were used to evaluate shoulder function. MRI was used to assess preoperative fatty infiltration (FI), atrophy, modified Patte's classification, PS-Tetra score and postoperative tendon integrity. The shoulder function was compared between groups of different PS-Tetra scores. The binary logistic regression was used to determine the risk factors of irreparability and retear.Results:83 cases of repair of posterosuperior massive rotator cuff tears were finally included. Complete repairs were performed in 83 cases, and partial repairs were performed in 12 cases. Retear was observed in 17 (20%) cases. The ASES scores (postoperative 58.52±8.33 vs. preoperative 47.30±17.40, t=-19.642, P<0.001), ROM of forward flexion (postoperative 157.60°±13.85° vs. preoperative 116.88°±50.89°, t=-7.272, P<0.001), external rotation (postoperative 45.26°±14.69° vs. preoperative 37.34°±18.65°, t=-4.043, P<0.001) and internal rotation [postoperative L 1 (T 7-buttock) vs. preoperative L 2 (T 7-buttock), Z=-2.737, P=0.006] were significantly improved postoperatively in the group with PS-Tetra score between 0 and 2. In the group with PS-Tetra score of 3 and 4, the ASES scores (postoperative 69.17±15.91 vs. preoperative 46.85±20.73, t=-11.167, P=0.001) were significantly improved postoperatively, while the ROMs were not. Modified Patte stageⅢ[ OR=26.827, 95% CI (2.089, 344.500), P=0.012] was the risk factor of irreparability. Dominant side involvement [ OR=9.407, 95% CI (1.044, 84.784), P=0.046) and PS-Tetra score of 3 and 4 [ OR=5.037, 95% CI (1.028, 26.623), P=0.046] were risk factors of retear. Conclusions:For repair of posterosuperior massive rotator cuff tears, preoperative PS-Tetra score of 3 and 4 was the risk factors of poor postoperative shoulder functions and retear.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.

The aim of this study was to investigate the impact of overexpressing 70-kD heat shock pro-teins(Hsp70)on glycolysis in C2C12 cells during myogenesis and adipogenesis.Using C2C12 cells as the research material,adenovirus was used to overexpress the Hsp70 gene,and changes in the expression of glycolytic genes were detected using fluorescence quantitative PCR and Western blotting techniques.The study indicated that during C2C12 cell myogenic differentiation,the expression trend of the Hsp70 gene was consistent with that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,suggesting a relationship between Hsp70 and the glycolytic pathway during myogenic differentiation.Overexpression of Hsp70 in the later stages of myogenic differentiation significantly upregulated the expression of Gsk3β,Pkm,Prk-ag3,and Pfkm genes(P＜0.05),with no significant impact on Hk-2 gene expression(P＞0.05).Dur-ing C2C12 cell adipogenic induction,the expression trend of the Hsp70 gene was similar to that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,indicating a relationship between Hsp70 and the glycolytic path-way during adipogenic induction.Following Hsp70 overexpression,in the later stages of adipogenic in-duction,the number of lipid droplets was significantly higher compared to the control group,with a sig-nificant upregulation of Gsk3β,Pkm,Prkag3,and Pfkm gene expression(P＜0.05),while Hk-2 gene expression was not significantly affected(P＞0.05).In conclusion,Hsp70 in C2C12 cells in myogenic and adipogenic states promoted the breakdown of glycogen into 6-phospho-glucose,thereby enhancing the glycolytic pathway,providing insights into the functional role of the Hsp70 gene in glycolysis in C2C12 cells.

Objective:To analyze the construction of human resources in specialized public health institutions in China,with a view to providing reference for strengthening the construction of human resources in public health in China.Methods:Based on the data of China Health and Wellness Statistical Yearbook,descriptive statistical analysis,Gini coefficient and health resource agglomeration were used to analyze the quantity and quality of human resources in specialized public health institutions and the equity of human resource allocation in different regions of China from 2012 to 2021.Results:From 2012 to 2021,the average annual growth rate of the number of specialized public health institution personnel nationwide was 4.10%,and the average annual growth rate of the number of specialized public health institution personnel per 1 000 population was 3.71%.In 2021,the Gini coefficient of human resources in China's specialized public health institutions allocated by population was 0.1002,and the Gini coefficient of the allocation of human resources according to the geographic area was 0.6706,and 21 provinces'health resource agglomeration value were greater than 1.Conclusion:the total amount of human resources in China's specialized public health institutions has steadily increased during the decade,and the quality has been greatly improved,but there is still a gap with the expected development goal;the development of human resources in different specialized public health institutions is not balanced;demographic fairness is better than geographic fairness in the allocation of human resources in public health,and there are significant inter-provincial differences.
