Objective:To compare bowel function 12 months after surgery between side-to-end anastomosis (SEA) and end-to-end anastomosis (EEA) groups of patients who had undergone rectal cancer resection.Methods:This single-center, prospective, open-label, phase III randomized controlled trial was approved by the Ethics Committee of Peking University People's Hospital (2018PHB040-01) and registered at ClinicalTrials. org (NCT03669237). Inclusion criteria were as follows: (1) histologically confirmed rectal adenocarcinoma; (2) tumor located 0 to 12 cm from the anal verge; (3) age≥18 years; and (4) planned R0 resection with primary reconstruction. Exclusion criteria included: (1) emergency surgery; (2) cognitive impairment; (3) non-primary anastomosis; (4) history of left-sided colonic or anorectal surgery; and (5) preexisting chronic defecation dysfunction. Eligible rectal cancer patients scheduled for elective sphincter-preserving surgery at Peking University People's Hospital were prospectively enrolled between October 2018 and March 2021 and randomly assigned to either the EEA group or the SEA group via computer-generated numbers prior to entering the operating room. All patients underwent standard radical tumor resection. Bowel function was evaluated by the low anterior resection syndrome (LARS) questionnaire. It consists of five single-choice questions and yields a total score ranging from 0 to 42. Defecation function is categorized into three levels: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The primary endpoint was the LARS score 12 months after surgery. Secondary endpoints included LARS scores from 1 to 11 months and during long-term follow-up(>12 months). The final follow-up was completed in July 2022. All randomized patients were included in the intention-to-treat set (ITTS). The full analysis set (FAS) was defined as ITTS patients with valid outcome data. All primary statistical analyses were performed in the FAS, and results were further compared in the per-protocol set (PPS) based on the actual treatment received.Results:A total of 323 patients underwent eligibility assessment, of whom 71 did not meet the inclusion criteria and 52 declined to participate. Ultimately, 200 patients were randomized. Median age was 64 years and 85 were women. The SEA and EEA groups comprised 102 and 98 patients, respectively. A total of 181 patients (90.5%) were included in the FAS, and 170 (85.0%) were included in the PPS. Among these, the 12-month LARS score was evaluated in 178 patients (98.3%) in the FAS and in 167 (98.2%) in the PPS. Median LARS score at 1–12 months were significantly lower in the SEA group in both the FAS dataset [12 months:8 (interquartile range [IQR], 0–22) vs. 14 (IQR, 8–29); Z=2.687, P=0.007] and the PPS dataset [12 months: 8 (IQR, 0–22) vs. 14 (IQR, 6–29); Z=2.543, P=0.011]. During long-term follow-up, the median LARS score was also significantly lower in the SEA group in the FAS dataset [2 (IQR, 0–4) vs. 11 (IQR, 2–23); Z=2.968, P=0.003] and the PPS dataset [2 (IQR, 0–14) vs. 11 (2, 27); Z=2.687, P=0.007]. Conclusion:Compared with the EEA group, bowel function was superior in the SEA group 1 year after surgery and during long-term follow-up.

Objective To analyze the epidemiological characteristics and immunization history of pertussis cases in Yichang City, Hubei Province from 2018 to 2023. Methods Data on the incidence and immunization history of pertussis cases were collected in Yichang City from 2018 to 2023, and the epidemiological characteristics was analyzed and described. Results A total of 109 cases of pertussis were reported in Yichang from 2018 to 2023, and the annual average reported incidence rate was 0.45/100,000. The incidence rate reported in each year was between 0～1.58/100,000. The area with the highest annual reported incidence rate was Xiling District (1.19/100,000). There was a statistically significant difference in the incidence rate between different years (χ²=208.26, P < 0.001). The annual reported incidence rate showed a significant increasing trend (χ² trend =125.71, P < 0.001). The ratio of male to female cases was 1.22. There was no significant difference in the annual reported incidence rates between males and females (χ²=0.85, P=0.36). Children aged 3-9 years accounted for 60.55%. Students and scattered children accounted for 45.87% and 36.70%, respectively. Before the onset of the disease, 72.48% had a history of immunization with pertussis-containing vaccine, and 27.52% had no history of immunization. The shortest interval between the last dose of pertussis-containing vaccine and the onset of the disease was 8 days, the longest was 4057 days, and the median was 1882 days. Conclusion From 2018 to 2023, the reported incidence of pertussis in Yichang City has been on the rise, with the majority of cases occurring in children and students under the age of 9. It is recommended to strengthen pertussis disease monitoring.

Objective:To analyze the correlation between caregiver characteristics and clinical manifestations of patients with Alzheimer′s disease (AD) dementia.Methods:It was a cross-sectional study. A total of 167 patients with AD dementia and 167 matched caregivers from Chinese Imaging, Biomarkers, and Lifestyle study of Alzheimer′s Disease (CIBL) study between January 1 and December 31, 2023 were consecutively selected as the study subjects. The data such as gender, age, body max index (BMI), waist to hip ratio, educational years, combined chronic diseases, disease course and the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Neuropsychiatric Inventory (NPI), Activities of Daily Living (ADL), Mini-Nutritional Assessment (MNA), and Dietary Diversity Score (DDS) of the patients were collected. The data such as gender, educational years, the relationship with patients, and the Caregiver Burden Inventory (CBI) score in the caregivers were also evaluated. According to the gender of caregivers, the patients were divided into female caregiver group (108 cases) and male caregiver group (59 cases). The Spearman correlation and multiple linear regression analyses were used to assess the impact of the caregiver characteristics on the cognitive function, NPS, activities of daily living, and nutritional status of the patients with AD dementia.Results:Among the 167 patients with AD dementia, 80 cases were men, and 87 cases were women, with a mean age of (68.43±7.51) years. Among the 167 matched caregivers, 59 were spouse, 98 were offspring, and 10 were others (nanny or other relatives). The AD patients in the male caregiver group had lower BMI and MNA scores than those in female caregivers′ group [(23.35±3.70) vs (24.80±3.33) kg/m 2, 22.00 (20.00, 24.50) vs 24.00 (21.00, 26.00) points] (both P<0.05). The educational years of the caregivers was negatively related to the ADL score ( r=-0.196), and was positively related to the MNA score of the patients ( r=0.180) (both P<0.05); while the CBI score of the caregiver was positively related to the age ( r=0.180), NPI score ( r=0.568) and ADL scores ( r=0.702) in the patients, and it was negatively related to the BMI ( r=-0.163), MMSE score ( r=-0.499), MoCA score ( r=-0.491) and MNA scores ( r=-0.387) in the patients (all P<0.05). The shorter educational years and elevated CBI score were independent risk factors for the decline in the MMSE score ( β=0.310, 95% CI: 0.021-0.598; β=-0.225, 95% CI:-0.297--0.154) and MNA score ( β=0.204, 95% CI: 0.067-0.340; β=-0.082, 95% CI:-0.116--0.049), as well as the increase in the NPI score ( β=-0.628, 95% CI:-1.208--0.047; β=0.575, 95% CI: 0.431-0.718) and ADL score ( β=-0.519, 95% CI:-0.860--0.179; β=0.361, 95% CI: 0.277-0.445) in the patients with AD dementia (all P<0.001). Conclusions:A low educational level of caregivers and a heavy caregiver burden are associated with decreased cognitive function, worsening NPS, reduced ADL, and declining nutritional status in patients with AD dementia.

Glutamate-ammonia ligase (GLUL, also known as glutamine synthetase) is a crucial enzyme that catalyzes ammonium and glutamate into glutamine in the ATP-dependent condensation. Although GLUL plays a critical role in multiple cancers, the expression and function of GLUL in gastric cancer remain unclear. In the present study, we have found that the expression level of GLUL was significantly lower in gastric cancer tissues compared with adjacent normal tissues, and correlated with N stage and TNM stage, and low GLUL expression predicted poor survival for gastric cancer patients. Knockdown of GLUL promoted the growth, migration, invasion and metastasis of gastric cancer cells in vitro and in vivo, and vice versa, which was independent of its enzyme activity. Mechanistically, GLUL competed with β-Catenin to bind to N-Cadherin, increased the stability of N-Cadherin and decreased the stability of β-Catenin by alerting their ubiquitination. Furthermore, there were lower N-Cadherin and higher β-Catenin expression levels in gastric cancer tissues compared with adjacent normal tissues. GLUL protein expression was correlated with that of N-Cadherin, and could be the independent prognostic factor in gastric cancer. Our findings reveal that GLUL stabilizes N-Cadherin by antagonizing β-Catenin to inhibit the progress of gastric cancer.

Objective:To analyze the correlation between blood pressure variability (BPV) and behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer′s disease (AD).Methods:In this retrospective cohort study, sixty-nine patients with AD from Beijing Tiantan Hospital, Capital Medical University, the Chinese Imaging, Biomarkers and Lifestyle Study of Alzheimer′s Disease were consecutively collected from February 1 to August 31, 2023. The patients were divided into the BPSD group (50 patients) and the control group (19 patients) according to with or without BPSD. The patients′ general information were collected, such as age at enrolment, gender, duration of education, and history of hypertension, diabetes, cerebral infarction, hyperlipoidemia, smoking, alcohol consumption, and carrier status of apolipoprotein E epsilon4 allele (APOE ε4). The 24-hour ambulatory blood pressure monitoring instruments were also used to collect the patients′ mean systolic blood pressure, mean diastolic blood pressure and 12 BPV indicators, which covered standard deviation (SD) and coefficient of variation (CV) of systolic and diastolic blood pressure throughout the day, daytime and nighttime. The Montreal Cognitive Assessment (MoCA) was used to assess their cognitive function, and the Activity of Daily Living (ADL)-14 items was used to assess their daily living abilities; hypothesis tests were used to compare the general information, MoCA scores, ADL-14 items scores, mean blood pressure and BPV indicators between the two groups; the multivariate logistic regression analysis was conducted to explore the related factors of BPSD in AD patients; Spearman correlation analysis was used to test the correlation between the total score of neuropsychiatric inventory (NPI) and BPV indicators in AD patients with BPSD.Results:In the BPSD group, the incidence rate of hypertension and MoCA scores were both significantly lower than those in the control group [44.00% vs 73.70%, (9.72±5.60) vs (14.53±5.52) points], but ADL-14 items scores and nocturnal systolic blood pressure CV were both significantly higher [23.00 (17.00, 29.25) vs 14.00 (14.00, 17.00) points, 8.89%±2.26% vs 7.52%±2.30%] (all P<0.05). Elevated ADL-14 items scores ( OR=1.379, 95% CI: 1.131-1.681) and nocturnal systolic blood pressure CV ( OR=1.387, 95% CI: 1.003-1.918) were positive correlation factors for the risk of BPSD in AD patients (all P<0.05). The daytime systolic blood pressure SD ( r=0.375) and CV ( r=0.357) were both positively correlated with total NPI scores in AD patients with BPSD (all P<0.05). Conclusion:BPV is correlated with BPSD in AD patients. Nocturnal systolic blood pressure CV is a positive correlation factor for the risk of BPSD in AD patients, and the total scores of NPI in AD patients are positively correlated with daytime systolic blood pressure SD and CV. It suggests that controlling BPV is a potential therapeutic measure to improve the BPSD of AD patients.
