ObjectiveTo investigate the characteristics of gray matter structure and clinical symptoms in patients with Alzheimer's disease （AD） comorbid with apathy （AD-A）. MethodsThe study included 30 patients with AD-A， 30 AD disease patients without apathy （AD without apathy， AD-NA）， and 30 healthy controls （HCs） matched in gender， age， and years of education. All participants underwent a comprehensive neuropsychological assessment and magnetic resonance imaging （MRI） scans. Voxel-based morphometry （VBM） was used to analyze changes in gray matter volume among the three groups. Additionally， the correlation between the identified abnormal brain regions and apathy scale scores was analyzed. ResultsThere were no statistically significant differences among the three groups in terms of age， gender， years of education， or total intracranial volume. Compared with the HCs group， both the AD-A and AD-NA groups showed significantly lower scores in cognitive function （P<0.001）. The AD-A group exhibited significantly higher apathy scale scores compared with the AD-NA group （P<0.001）. Compared with the AD-NA group， the AD-A group showed reduced gray matter volume in the bilateral caudate nucleus， left orbitofrontal cortex， lingual gyrus， inferior frontal gyrus， superior frontal gyrus， entorhinal cortex， right middle frontal gyrus and posterior cingulate cortex （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-A group exhibited reduced gray matter volume in the bilateral middle temporal gyrus， left fusiform gyrus， calcarine sulcus， postcentral gyrus， right inferior frontal gyrus and supramarginal gyrus （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-NA group showed reduced gray matter volume in the left precuneus， inferior temporal gyrus， and right inferior temporal gyrus （FWE-corrected， P<0.05 for all）. In the AD-A group， changes in the gray matter volume of the left caudate nucleus （r= -0.557， P=0.002） and right middle frontal gyrus （r=-0.620， P=0.001） were negatively correlated with the apathy evaluation scale （AES） scores. ConclusionPatients in the AD-A group exhibited significant atrophy in the frontal-temporal-basal ganglia circuit， and the degree of gray matter atrophy was correlated with the severity of apathy.

Objective:To evaluate the anti-reflux effect of digestive tract reconstruction using esophageal-tubular gastric asymmetric anastomosis after radical resection of esophageal and esophagogastric junction cancer.Methods:The main steps were as follows:(1)oblique incision of the lower esophagus;(2)curved incision of the tubular anterior gastric wall;(3)the lower end of the esophagus was anastomosed to the tubular gastric incision with a 90-degree torsion; (4)The anterior wall of the anastomosis was reinforced with a transverse-inverted suture,the posterior wall with a folded suture,and the corners of the gastric stump were buried with sutures.The anastomosis operation time,postoperative complications and postoperative hospital stay were recorded;the reconstructed structure and anti-reflux effect of the anastomosis were observed by digestive tract radiography,gastroscopy and follow-up investigation.Results:The Department of Gastrointestinal and Thoracic Surgery of Huaian First People's Hospital, affiliated to Nanjing Medical University, treated 5 patients of esophagogastric junction cancer and 20 esophageal cancer cases between August 2022 and November 2024, including 19 men and 6 women, with a mean age of (66.7±7.4) years. The mean anastomosis time was (35.4±5.9) minutes, the intraoperative blood loss was (117.6±33.4) ml and the mean postoperative hospital stay was(16.6±5.2) days, with no complications such as anastomotic leakage and bleeding. Postoperative digestive tract radiography (Trendelenburg position)showed that all the patients had no contrast reflux,gastroscopy showed no signs of reflux esophagitis and bile reflux gastritis, the anastomosis showed an inverted whiskers valve-like structure. The median follow-up time was (16.8±6.3) months, and all patients had no reflux symptoms such as acid reflux and belching,and no acid suppressive medication was needed.Conclusion:The esophageal-tubular gastric asymmetric anastomosis is a safe and effective antireflux reconstruction technique.

Objective:To comparatively evaluate the efficacy of anti-tumor necrosis factor (TNF)-α and anti-interleukin (IL)-12/23 biologics as the first-line treatment in Crohn′s disease (CD).Methods:From January 1, 2016 to December 31, 2024, at the Department of Gastroenterology of the First Affiliated Hospital of Soochow University, the clinical data of patients with CD treated with anti-TNF-α (infliximab or adalimumab) or anti-IL-12/23 biologics (ustekinumab) as first-line treatment were retrospectively collected. All the patients were followed up for 1 year since the initiation of first-line biologic treatment, with the follow-up concluding on December 31, 2024. The primary outcomes were the clinical efficacy (including clinical response rate and clinical remission rate) of anti-TNF-α or anti-IL-12/23 treatment at week 24 and week 48, and the endoscopic efficacy(including endoscopic response rate and endoscopic remission rate) at week 48. The clinical efficacy was assessed based on Crohn′s disease activity index(CDAI). The clinical response was defined as a reduction in CDAI by ≥ 70 from baseline (week 0), and clinical remission was defined as CDAI < 150. The endoscopic efficacy was assessed based on simple endoscopic score for Crohn′s disease (SES-CD), the endoscopic response was defined as a reduction in SES-CD by ≥50% from baseline (week 0), and endoscopic remission was defined as SES-CD ≤2. Chi-square test or Fisher′s exact test was used for statistical analysis.Results:A total of 215 CD patients were enrolled, including 160 males and 55 females, with the age of (31.88±11.55) years old. Among them, 179 patients completed the clinical efficacy evaluation, 110 cases were treated with anti-TNF-α, 69 cases were treated with anti-IL-12/23. The clinical response rates of patients treated with anti-TNF-α and anti-IL-12/23 at week 24 were 95.5%(105/110) and 95.7%(66/69), respectively, and the clinical remission rates at week 24 were 86.4%(95/110) and 85.5%(59/69), respectively; the clinical response rates at week 48 were 95.5%(105/110) and 97.1%(67/69), respectively, and the clinical remission rates at week 48 were 89.1%(98/110) and 88.4%(61/69), respectively; and the differences were not statistically significant(Fisher′s exact test, χ2=0.03, Fisher′s exact test, χ2=0.02; P=1.000, 0.708, 0.872, and 0.887). A total of 76 patients completed endoscopic efficacy evaluation, among which 55 cases were treated with anti-TNF-α, and 21 cases were treated with anti-IL-12/23. The endoscopic response rates of patients treated with anti-TNF-α and anti-IL-12/23 were 74.5%(41/55) and 66.7%(14/21), respectively, and the endoscopic remission rates at week 48 were 49.1%(27/55) and 28.6%(6/21), respectively; and the differences were not statistically significant( χ2=0.47 and 2.60, P=0.492 and 0.107). Conclusion:Both anti-TNF-α and anti-IL-12/23 are effective as first-line biological therapies for CD, and there are no significant differences in both clinical and endoscopic efficacy between these 2 biologics.

Objective:To compare the role of double-balloon enteroscopy (DBE) and dual-energy CT enterography (DCTE) in evaluating the clinical characteristics of Crohn′s disease (CD).Methods:From July 1, 2016 to November 1, 2023, 72 patients with CD who underwent both DBE and DCTE (with an interval of less than 3 months) in the First Affiliated Hospital of Soochow University were enrolled in this retropective study. Among them, 4 patients underwent both DBE and DCTE twice (a total of 76 cases). The data of DBE and DCTE in the diagnosis of 76 CD cases were analyzed, including the diagnostic rate of CD, the consistency of the 2 methods in detecting the lesion location (ileocecal, colonic, ileocolonic, and upper gastrointestinal tract involvement), and the detection rates of stenosis, ulcer and the location, long ulcer (long-diameter≥2 cm), and fistula. Kappa test was performed for the consistency analysis, and Chi-square test was used for statistical analysis.Results:The diagnostic rate of CD by DBE was higher than that by DCTE (80.3% (61/76) vs. 65.8% (50/76)), and the diagnostic rate of combination of the 2 methods (89.5% (68/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=4.04 and 12.28, P=0.044 and <0.001). The result of Kappa consistency test showed that the consistency of CD lesion location detected by DBE and DCTE was poor (Kappa value=0.29, t=3.17, P=0.002). The detection rate of stenosis by DBE was higher than that by DCTE (46.1% (35/76) vs. 13.2% (10/76)), the detection rate of stenosis by combination of the 2 methods (52.6% (40/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=19.73 and 26.82, both P<0.001). There were no statistically significant differences in the detection rates of fistula among DBE, DCTE, and the combination of the 2 methods (3.9%(3/76), 2.6% (2/76), 5.3% (4/76); all P>0.05). The detection rate of ulcer by DBE was higher than that by DCTE(73.7% (56/76) vs. 7.9% (6/76)), the detection rate of ulcer by combination of the 2 methods (76.3%(58/56)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=68.10 and 72.98, both P<0.001). The detection rates of long ulcer and non-terminal ileum ulcer by DBE were both 17.9% (10/56). All the 6 cases with ulcer detected by DCTE were located in the terminal ileum, and no long ulcers were observed. Conclusions:In the diagnosis of CD, as well as in the detection of stenosis and ulcer, DBE and the combination of DBE and DCTE have more advantages over DCTE alone. The consistency between DBE and DCTE in identifying the location of lesion is poor. DBE has advantages in detecting long ulcer and non-terminal ileum ulcer.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To understand the serologic prevalence and infection status of Cytomegalovirus(CMV)in children aged 0～1 years,and explore the risk factors of CMV infection for clinical reference.Methods The data of 4 938 children aged 0～1 years who underwent chemiluminescence enzyme immunoassay for TORCH in Department of Inpatient and Department of Pediatrics Outpatient of Maternal and Child Health Hospital of Inner Mongolia from January 2020 to December 2022 were retrospectively analyzed to understand the seroprevalence of human CMV(HCMV)among children in the region,and analyzed the risk factors associated with HCMV infections by combining the results of laboratory tests and clinical information.Results In 4 938 children,the total antibody positivity rate was 94.01%(4 642/4 938),the total IgG antibody positivity rate was 93.86%(4 635/4 938),the total IgM antibody positivity rate was 8.10%(400/4 938),and the positive rate of the two simultaneous detections was 7.96%(393/4 938).The difference in HCMV-IgG and HCMV-IgM antibodies positivity rates beteen different age groups were statistically significant(χ2=36.350,1 043.199,all P<0.05),and the differences in HCMV-IgG and IgM antibodies between boys and girls were not statistically significant(χ2=0.215,1.184,all P＞0.05).According to univariate analysis,the breast-feeding and vaginal delivery rates in the infected group were higher than those in the control group,and the differences in feeding and birth methods were statistically significant(χ2=10.777,5.725,all P<0.05).Multifactorial analysis found that breast-feeding and transvaginal delivery were independent risk factors for HCMV infection,and the differences was statistically significant(Wald χ2=6.247,10.057,all P<0.05).Conclusion The serologic antibody positivity rate of HCMV in children within 1 year of age is as high as 94.01%,and infants aged 3 months to 6 months are most susceptible to infection.Breastfeeding and transvaginal delivery are independent risk factors for HCMV infection in children within 1 year of age.
