The objective of this study was to examine the effects of electroacupuncture on the expression of ATP-binding cassette transporter A1(ABCA1),ATP-binding cassette transporter G1(ABCG1),and class B type Ⅰ scavenger receptor(SR-B Ⅰ)genes and proteins in peritoneal macrophages of atherosclerotic rabbits.The study aimed to explore the mechanism underlying the treatment of atherosclerosis(AS)with electroacupuncture.Methods Twenty-six male New Zealand rabbits were randomly divided into the negative control group(n=7)and the modeling group(n=19)using a random number table method.The negative control group rabbits were fed a regular diet,while the modeling group was induced with a combination of high-fat feed and common carotid artery balloon injury surgery to create an AS model.After successful modeling,the rabbits in the modeling group were further divided into the model group,the electroacupuncture group,and the atorvastatin group,with 6 rabbits in each group.The rabbits in the electroacupuncture group received electroacupuncture at"'Neiguan'(PC6)","'Zusanli'(ST36)",and"'Guanyuan'(ST25)"acupoints,using a density wave,a current of 1 mA,and a frequency of 4 Hz/20 Hz,once a day.The needle was retained for 20 minutes each time,and a total of 4 courses of treatment were conducted,with 6 days per course.The rabbits in the atorvastatin group were administered atorvastatin calcium tablet suspension(1 mg/kg)orally once a day,for 6 days per course,with a total of 4 courses.After the interventions,HE staining was performed to observe the morphological changes in the common carotid artery tissue of the rabbits.Peritoneal macrophages were collected from the rabbits,and the mRNA expression levels of ABCA1,ABCG1,and SR-B Ⅰ were measured using real-time fluorescence PCR.The protein expression levels of ABCA1,ABCG1,and SR-B Ⅰ were detected using Western blotting.Results The negative control group exhibited smooth intima of common carotid artery in rabbits,while the model group displayed damaged intima of common carotid artery,thickened artery walls,and the formation of atherosclerotic plaques.The electroacupuncture group and atorvastatin group showed significant improvements in wall thickening and a reduction in plaque area.Compared with the negative control group,the mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits in the model group were reduced(P＜0.01).Compared with the model group,the electroacupuncture group and atorvastatin group exhibited increased mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in abdominal macrophages of rabbits(P＜0.01).Furthermore,the atorvastatin group demonstrated increased mRNA levels of ABCG1 and SR-B Ⅰ,as well as increased protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits,in comparison to the electroacupuncture group(P＜0.01).Conclusion Electroacupuncture can enhance the expressions of ABCA1,ABCG1,and SR-B Ⅰ mRNA and protein in abdominal macrophages of AS rabbits,thereby promoting the process of cholesterol reverse transport.This may be one of the mechanisms underlying the effectiveness of acupuncture in the treatment of AS.

Objective:To analyze the clinical value of 18F-FDG PET/MR for precise localization of epileptogenic foci in patients with refractory epilepsy. Methods:From February 2019 to December 2021, 81 patients (52 males, 29 females; age (30.0±10.9) years) with refractory epilepsy confirmed in Ruijin Hospital Shanghai Jiao Tong University School of Medicine were retrospectively enrolled. All patients underwent preoperative PET/MR exam, and the possible position of the epileptogenic foci were determined by PET/MR imaging and pre-surgical evaluation, then the stereoelectroencephalography (SEEG) electrodes were implanted. Surgery was performed, and outcome was assessed by using a modified Engel classification two years after surgery. χ2 test was used to compare the detection rates of MRI and PET/MR fusion imaging in localizing epileptogenic foci and the detection rates of epileptogenic foci in temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE) by PET/MR. Results:MRI correctly localized seizure foci in 38 patients, with the detection rate of 46.91%(38/81), while PET/MR detected seizure foci in 73 patients, with the detection rate of 90.12%(73/81; χ2=35.05, P<0.001). There were 63 TLE and 18 ETLE patients. The detection rate of PET/MR in localizing seizure foci in TLE patients was 95.24%(60/63), which was significantly higher than that in ETLE patients (13/18; χ2=5.94, P=0.015). After 2 years follow-up, the postoperative efficacy rate of TLE patients with Engel grades Ⅰ-Ⅱ was 76.19%(48/63), which was 13/18 of ETLE patients ( χ2=0.12, P=0.731). Conclusion:Hybrid PET/MR imaging can accurately locate epileptogenic foci, especially for MRI negative lesions, which provides precision imaging information for surgical planning and improves surgical success rate.

Objective To explore the potential influencing factors and complex pathways affecting rehabilitation effect for children with autism spectrum disorder(ASD)from the perspective of parental efficacy in doctor-patient communication,and to provide evidence for improving the quality of rehabilitation service for children with ASD. Methods An anonymous face-to-face questionnaire survey was conducted to collect general demographic information of parents of children with ASD at designated rehabilitation institutions in Gansu province.The data included paren-tal efficacy in doctor-patient communication,parental compliance of treatment and children's rehabilitation out-comes were collected.A structural equation model was used to explore the impact mechanism of parental commu-nication efficacy on the rehabilitation outcomes of children with ASD. Results Data from 519 parents at 37 rehabilitation institutions across 13 cities/counties in Gansu province were collect-ed.Significant positive correlations were found between parental efficacy in doctor-patient communication,doc-tor-patient relationships,parental compliance with treatment and rehabilitation outcomes for children with ASD(P＜0.05).Through structural equation model analysis,the standardized direct effect of children with ASD from parents'doctor-patient communication efficacy was 0.151(P=0.023).The mediating effect of doctor-patient rela-tionship and parental compliance with treatment were 0.160(P=0.001)and 0.111(P=0.001),respectively,with a chained mediating effect of 0.035(P=0.001).The pathway"parental efficacy in doctor-patient communica-tion → doctor-patient relationship → ASD child's rehabilitation outcome"accounted for the highest proportion of the total mediating effect,at 52.29%. Conclusion Parental doctor-patient communication efficacy may positively impact on the rehabilitation outcomes of chil-dren with ASD directly,and indirectly through the doctor-patient relationship and parental compliance with treat-ment.Rehabilitation institutions should focus on fostering parental communication skills and enhancing high-quality and humanized rehabilitation services.

Objective: To understand the current status of main professional work in independent school health departments of Chinese centers for disease control and prevention, so as to provide reference and suggestions for the further development of school health work in China. Methods: Electronic questionnaire was used to collect the basic work of school health, the monitoring work, the intervention action of common diseases and the development of health intervention among students in independent school health departments of centers for disease control and prevention in China. Results: Among the 357 institutions that have set up independent school health departments, the implementation rates of school mental health work, safety emergency and risk avoidance health intervention were low, which were 11.8% and 11.5%, respectively. Relying on the project "national monitoring and intervention of common diseases and health influencing factors of students", the overall implementation of health monitoring in schools nationwide was successful, but the overall implementation rate of students nutritional status monitoring and "healthy parents action" were low, accounting for 44.5% and 24.4%, respectively. At the same time, there were still as many as 27.2% institutions that had not carried out the intervention action for common diseases of students which advocated in the monitoring program. The failure rate of county level institutions was higher than that of provincial level and prefecture level institutions, and the failure rate of the central and western institutions was much higher than that of the eastern institutions; the difference was statistically significant( χ 2=30.1, 41.6, P <0.05). Conclusion We should increase support including policy preference, fund guarantee, technical guidance and so on for the school health work of disease control institutions at the grass roots level and in economically underdeveloped areas, so as to ensure the healthy growth of children and adolescents in all respects.

Objective:To investigate the effect of the duration of preoperative biliary drainage on postoperative complications after pancreaticoduodenectomy.Methods:The clinical data of 102 patients with benign and malignant hepatopancreatic ductal periampullary tumors who underwent pancreaticoduodenectomy and preoperative biliary drainage in Beijing Friendship Hospital, Capital Medical University from January 2016 to July 2020 were retrospectively analyzed. According to the median duration of preoperative biliary drainage, the patients were divided into short-term drainage group (≤ the median duration of biliary drainage) and long-term drainage group (> the median duration of biliary drainage). The general data, the effect of biliary drainage, inflammation-related indicators and postoperative complications were compared between the two groups. Multivariate logistic regression was used to screen the risk factors related to the postoperative severe complications.Results:Of the 102 patients, 68 (66.7%) were males and 34 (33.3%) were females, with a median age of 63 years (43-80 years). The median duration of preoperative biliary drainage was 14 d. There were 68 patients in short-term drainage group and 34 patients in long-term drainage group. There were no statistically significant differences in age, gender, body mass index (BMI), hypertension, diabetes mellitus, surgery history of upper abdominal, American Society of Anesthesiologists (ASA) grade, carcinoembryonic antigen, carbohydrate antigen 125, alpha-fetoprotein, prothrombin time, pancreaticojejunostomy method, operation time, and pathological type between the two groups (all P > 0.05). However, patients in long-term drainage group had higher conversion rate, more blood loss and longer hospital stay compared with those in short-term drainage group (all P < 0.05). Before biliary drainage, alanine aminotransferase (ALT) level in short-term drainage group was higher than that in long-term drainage group ( Z = -2.59, P = 0.009), and there were no statistically significant differences in aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TB) and direct bilirubin (DB) levels between the two groups before biliary drainage (all P > 0.05). After biliary drainage, DB in short-term drainage group was higher than that in long-term drainage group ( Z = -3.34, P = 0.001), and there was no statistically significant difference in ALT, AST, ALB, TB levels between the two groups (all P > 0.05). There were no statistically significant differences in the levels of white blood cells, neutrophils, lymphocytes and the ratio of neutrophils to lymphocytes between the two groups on the 1st and 3rd day after the operation (all P > 0.05). The total incidence of postoperative related complications in short-term drainage group and long-term drainage group was 63.2% (43/68), 70.6% (24/34), respectively, and the difference was statistically significant ( χ2 = 0.54, P = 0.461); the incidences of bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying, all grades of pancreatic leakage, grade B and C pancreatic leakage were not statistically different between the two groups (all P > 0.05); the incidence of severe postoperative related complications in short-term drainage group was higher than that in long-term drainage group [27.9% (19/68) vs. 8.8% (3/34), χ2 = 4.90, P = 0.027]. Multivariate logistic regression analysis showed that the long-term preoperative biliary drainage was an independent protective factor for postoperative severe complications (long-term drainage vs. short-term drainage: OR = 0.253, 95% CI 0.066-0.975, P = 0.046), while BMI ( OR = 1.174, 95% CI 0.986-1.398, P = 0.071) and pathological type (benign or borderline vs. malignant tumor: OR = 0.247, 95% CI 0.043-1.419, P = 0.117) were not independent influencing factors for postoperative severe complications. Conclusions:Short-term biliary drainage (≤14 d) is a risk factor for postoperative severe complications in patients with hepatopancreatic ductal periampullary tumor undergoing preoperative biliary drainage. Preoperative biliary drainage time is not associated with postoperative total complications, pancreatic leakage, bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying.

Objective:To explore the relationship between the occurrence and development of colorectal cancer and the risk of BRCA1 and BRCA2 gene mutations. Methods:Sixty-one patients with colorectal adenocarcinoma admitted to Beijing Friendship Hospital Affiliated to Capital Medical University from January 2022 to March 2022 were tested by second-generation sequencing. Information such as age of onset, gender, histological grade and TNM stage were collected. According to whether the BRCA1 and BRCA2 gene had systemic mutation, the patients were divided into BRCA1 and BRCA2 gene system mutation group and unmutated group. There were 8 cases in the BRCA1 and BRCA2 gene system mutant group and 53 cases in the non-mutant group. The main outcome measures were the relationship between pathogenic or likely pathogenic germline mutations in colorectal cancer and clinicopathological data of patients, including age of onset, gender, tumor location, TNM stage, histological differentiation, and family history. The secondary outcome was the relationship between BRCA1 and BRCA2 gene system mutations and clinicopathological data. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and comparison between groups was analyzed using the t-test. Measurement data with non-normal distribution were represented as M ( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Measurement data were expressed as the number of cases or percentage (%), and Chi-square test was used for comparison between groups. Results:Among 61 colorectal adenocarcinoma patients, the frequency of pathogenic or potentially pathogenic germ line mutations in colorectal cancer was 13.1% (8/61), and the frequency of BRCA1 and BRCA2 mutations was 3.3% (2/61). The frequency of BRCA1 and BRCA2 mutations was 13.1% (8/61). Women with BRCA1 and BRCA2 mutations (75.0% vs 37.7%, χ2=3.947, P=0.047) and right colon cancer (75.0% vs 26.4%, χ2=7.889, P=0.019) were significantly higher than those without mutation. Conclusions:The frequency of BRCA1 and BRCA2 gene mutation is higher in colorectal cancer patients. BRCA1 and BRCA2 gene mutations are recommended for colorectal cancer patients with a family history of breast or ovarian cancer.

Objective:To investigate the association between cancer fatalism and optimistic attitudes among colorectal cancer patients, and how the above linkage is moderated by the involvement of patients′ opinions, the family members′ opinions and the physicians′ opinions in treatment decision-making.Methods:A cross-sectional survey was conducted on 64 patients diagnosed with colorectal cancer and awaiting radical colorectal cancer surgery in the Department of General Surgery of Beijing Friendship Hospital Affiliated to Capital Medical University, from January 2021 to December 2021. There were 38 males and 26 females, aged (61.2±13.0) years from 30 to 84 years. Cancer fatalism, optimism attitudes, and the involvement of patients′ opinions, the family members′ opinions and the physicians′ opinions in treatment decision-making were assessed. The patients′ cancer fatalism beliefs were measured by the " Chance" subscale of the Form C of the Multidimensional Health Locus of Control (MHLC-C), optimism attitudes were assessed by the Chinese version of the revised Life Orientation Test (CLOT-R), and the influence of patients′, family members′, and physicians′ opinions in the medical decision-making process was measured by a self-designed single factor scale. Measurement data of normal distribution were expressed as mean±standard deviation ( ± s). Measurement data of skewed distribution were expressed as M( Q1, Q3). Spearman correlation analysis and Chi-square test was used to examine the association between the main outcome variable (patients′ optimistic attitudes) and demographic and clinical characteristics. Interaction was examined by hierarchical linear regression analysis combined with simple slope tests. Results:Cancer fatalism was negatively associated with patients′ optimistic attitudes ( r=-0.35, P<0.01). Optimistic attitude of patients was significantly and negatively correlated with the influence of family members′ opinions on medical decision-making ( r=-0.25, P<0.05). There were significant positive correlations between the influence of patients′ and family members′ opinions ( r=0.50, P<0.01), family members′ and physicians′ opinions ( r=0.67, P<0.01), and physicians′ and patients′ opinions ( r=0.38, P<0.01) in medical decision making. Hierarchical linear regression analysis showed a negative association between cancer fatalism and optimism ( β=-0.32, P=0.01). This association was further moderated by the involvement of family members′ opinions ( β=-0.56, P<0.01) and the involvement of physicians′ opinions ( β=-0.36, P=0.04) in medical decision-making. Simple slope tests revealed that the negative impact of fatalistic attitudes on patients′ optimism attitudes may be potentiated when family members′ opinions have high influence on medical decision-making, while the negative impact may be buffered to some extent when physicians′ opinions have high influence on medical decision-making. Conclusions:Cancer fatalism had a negative effect on patients′ optimism. The high influence of physicians in treatment decision-making buffered the negative effect of cancer fatalism on optimism; the high influence of family members in treatment decision-making potentiated the negative effect of cancer fatalism on optimism. In the process of doctor-patient communication and shared decision-making, for patients with strong fatalistic attitudes, consideration should be given to appropriately increasing direct informational communication between physicians and patients and reducing excessive family intervention in medical decision-making, so as to enhance patients′ autonomy for treatment, promote optimism, and reduce the negative effects of cancer fatalism.

Objective:To investigate the influencing of preoperative biliary drainage on surgery-related complications after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinical data of 267 patients with periampullary space-occupying lesion who were admitted to Beijing Friendship Hospital of Capital Medical University from January 2016 to July 2020 were collected. There were 166 males and 101 females, aged 61 (range, 54?84)years. Observation indicators: (1) comparison of preoperative situations in patients with and without preoperative biliary drainage; (2) comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage; (3) methods and efficacy of preoperative biliary drainage; (4) factors influencing surgery-related complications after pancreaticoduodenec-tomy. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(rang) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney 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 conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Comparison of preoperative situations in patients with and without preoperative biliary drainage. Of the 267 patients, there were 104 cases with preoperative biliary drainage and 163 cases without preoperative biliary drainage. Cases with malignant tumor, cases with borderline tumor, cases with chronic pancreatitis were 89, 13, 2 in patients with preoperative biliary drainage, versus 111, 41, 11 in patients without preoperative biliary drainage, showing significant differences in pathology type between them ( χ2=10.652, P<0.05). (2) Comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage. There was no significant difference in operation time, volume of intra-operative blood loss, postoperative complications, grade B pancreatic fistula, grade C pancreatic fistula, biliary leakage, abdominal or gastrointestinal bleeding, incidence of abdominal infection, white blood cell count at postoperative day 1, white blood cell count at postoperative day 3, neutrophil-to-lymphocyte ratio at postoperative day 1, neutrophil-to-lymphocyte ratio at postoperative day 3, C-reactive protein-albumin ratio at postoperative day 1, C-reactive protein-albumin ratio at post-operative day 3, duration of hospital stay between the 104 patients with preoperative biliary drainage and the 163 patients without preoperative biliary drainage ( P>0.05). (3) Methods and efficacy of preoperative biliary drainage. Of the 104 patients with preoperative biliary drainage, there were 40 cases receiving endoscopic nasobiliary drainage with drainage time as (12±2)days, there were 38 cases receiving percutaneous transhepatic cholangial drainage with drainage time as (7±1)days, and there were 26 cases receiving endoscopic retrograde biliary drainage with drainage time as (19±2)days. The total bilirubin, direct bilirubin, aspartate transaminase, alanine aminotrans-ferase in 104 patients were (223±18)μmol/L, (134±11)μmol/L, (112±10)U/L, (160±16)U/L before biliary drainage and (144±13)μmol/L, (84±8)μmol/L, (79±8)U/L, (109±12)U/L after biliary drainage, showing significant differences in the above indicators ( t=3.544, 3.608, 2.523, 2.509, P<0.05). (4) Factors influencing surgery-related complications after pancreatocoduodenectomy. Results of multi-variate analysis showed that operation time was an independent factor influencing surgery-related complications after pancreaticoduodenectomy ( odds ratio=1.005, 95% confidence interval as 1.002?1.008, P<0.05). Conclusions:Preoperative biliary drainage does not increase the incidence of complications related to pancreaticoduodenectomy in patients with periampullary space-occupying lesion. Operation time is an independent factor influencing postoperative surgery-related complications.

Objective:To explore the practical application and clinical significance of modified grading system for Gastrointestinal Symptom Rating Scale (GSRS) scores in evaluating long-term postoperative gastrointestinal dysfunction (PGID) in patients after colon cancer surgery.Methods:A retrospective analysis was conducted on the case data of 122 patients who underwent right hemicolectomy for colorectal cancer at Beijing Friendship Hospital, Capital Medical University from September 2021 to September 2022. Among these patients, 69 were males (56.6%), and 53 were females (43.4%). The median age was 66.5 years, and the body mass index was (24.4±3.3) kg/m 2. The main observe indiator was GSRS scores of patients. The measurement data of normal distribution were represented as mean±standard deviation( ± s), and intergroup comparisons were conducted using ANOVA. The measurement data of non-normal distribution were expressed as the median (interquartile distance) [ M( Q1, Q3)], the Kruskal-Wallis H test was employed. Unordered count data comparisons were performed using the χ2 test, while comparisons for ordered count data between groups were conducted using the Kruskal-Wallis H test. GSRS scores were represented using density plots, and the scores were categorized into five symptom groups, presented using radar charts to illustrate the distribution of each symptom group. Results:Among the 122 patients, the most common long-term PGID syndromes was dyspepsia, followed by abdominal pain, diarrhea, and constipation. GSRS score data in the study population exhibited a nearly trimodal trend. Based on the overall data trend, the GSRS scale was refined, with cut-off values of 20 and 30, categorizing patients with right-sided colon cancer into low-risk, moderate-risk, and high-risk groups for quantifying the severity of long-term PGID. In terms of gender distribution, the differences among the three groups was statistically significant ( P=0.031), suggesting that males may be more susceptible to long-term PGID. However, there were no significant differences among the three groups concerning age, tumor location, surgical approach, anastomotic technique, lymph node dissection, pathological staging, adjuvant chemotherapy, and other factors. Conclusions:The modified grading system for GSRS scores aligns with the distribution characteristics of postoperative gastrointestinal function in colorectal cancer patients. It can quantify the risk of long-term PGID, allowing for a graded management approach to improve the postoperative quality of life for patients.

Objective: To learn about the construction and staffing of the school health system in Chinese institutions for disease prevention and control, and to provide basic information for the school health system, team capacity building and work development. Methods: Electronic questionnaire was used to collect the setting and staffing of school health departments (including school health centers and departments/rooms) at the provincial, prefecture and county (district) levels in the centers for disease control and prevention. Statistical analysis was made on the proportion of school health, the number of staff and the characteristics such as age, education, major and working years in the provincial, prefecture and county (district) levels. Results: Among the 3 313 institutions, the proportion of independent school health departments was 10.8%, and those of the provincial, prefecture and county (district) levels were 74.2%, 15.0%, and 9.6%, respectively. Among the institutions with separated department, the average number of staff members was 4.4, while the number of staff was 2.5. The average age of school health workers was 40.4 years old, and the proportion of male and female employees was 45.2% and 54.8%. The proportion of personnel who have been engaged in school health work for less than 5 years on average was as high as 65.1%. The majors of the staff were mainly public health ( 40.4 %), 54.0% of the provincial staff had a master s degree or above, and 47.8% and 58.7% of the staff at the prefecture and county (district) levels were junior college or below respectively.The proportion of provincial level personnel with intermediate and senior titles was 69.6%, and the proportion of municipal and countylevel personnel at the junior level and below was 52.2% and 56.2% respectively. Conclusion The proportion of independent school health departments within centers of disease control and prevention across China was low. There is a serious shortage of school health personnel, and there are problems such as low levels of education and professional titles, especially in county (district) level institutions. It is urgent to strengthen the construction of the school health system of the centers for disease control and prevention in China.
