Objective To investigate the application effect of a refined early diet plan in patients with distal gastric cancer after laparoscopic radical surgery.Methods By convenience sampling method,46 patients with laparoscopic radical gastrectomy for distal gastric cancer admitted to a tertiary hospital in Zhejiang Province from July to December 2023 were selected as an experimental group,while 49 patients admitted from January to June 2023 as a control group.The experimental group was administered with the refined early diet plan,and the control group was administered with conventional methods.The intervention period was from the first day after surgery to discharge.The differences of the first postoperative defecation time,perioperative thirst and hunger score,postoperative hospitalization time,hospitalization cost,postoperative complications and the incidence of readmission 30 days after surgery were compared between the 2 groups.Results 42 patients in the experimental group and 49 patients in the control group completed the study.First postoperative exhaust time(t=4.922,P＜0.001),first postopera-tive defecation time(Z=-2.440,P=0.015),perioperative thirst score(Z=-8.024,P＜0.001),perioperative hunger score(Z=-8.192,P＜0.00 1),postoperative hospitalization time(Z=-7.622,P＜0.001)and hospitalization cost(Z=-4.522,P＜0.001)were lower than those of the control group,and the difference was statistically significant.There was no significant difference in complication rate and 30-day readmission rate between the experimental group and the control group(P＞0.05).Conclusion The refined early diet plan is safe and effective for early recovery of patients after laparoscopic radical gastrectomy for distal gastric cancer,promoting intestinal function recovery,shortening hospital stay,reducing hospital costs,and improving patients'subjective comfort.

Objective: To explore sex difference in the cardiovascular health (CVH) status of 6-8 year old children in Beijing, so as to inform the early intervention of CVH related lifestyles. Methods: Based on the Beijing Children s Growth and Health Cohort (PROC), baseline physical examination, sequential questionnaire survey, and laboratory tests were conducted among 1 914 grade 1 students. Children s CVH and its subscales (health behaviors and health factors) scores were calculated according to the Life s Essential 8 (LE 8) index and categorized into high, moderate, and low CVH. CVH scores were reported as medians and interquartile ranges; sex differences were compared using the Chi square test and Wilcoxon test. Results: Among the 1 914 participants, the percentages of high, moderate, and low CVH were 35.7%, 63.5%, and 0.8%, respectively, and the percentages of high, moderate, and low health behavior scores were 25.9%, 67.5%, and 6.6%, respectively, with no statistically significant differences between sex ( χ 2=2.30, 0.07, P >0.05). The rates of high, moderate, and low health factor scores for boys and girls were 61.1%, 36.0%, 2.9% and 71.1%, 28.4%, 0.5%, respectively, with a statistically significant sex difference ( χ 2=31.88, P < 0.01). The overall CVH score was 76.0(70.0, 83.0), 76.0(69.0, 82.0) for boys, and 77.0(71.0, 83.0) for girls. Among the health behavior metrics, sleep scores were the best and physical activity scores were the worst[100.0(90.0,100.0), 40.0(20.0, 80.0 )]; among the health factor metrics, blood glucose scores were the best and lipid scores were the worst[100.0(100.0,100.0), 60.0(40.0,100.0)]. In respect to health factors, there were significant gender differences in body mass index, blood lipids, blood sugar, and blood pressure scores ( Z =-6.92, 3.01, -6.60, -2.30, <0.05), but there were no significant gender differences in diet, physical activity, nicotine exposure, or sleep scores with regards to health behaviors ( Z =0.99, 0.88, -0.13, 0.36, P > 0.05 ). Compared to boys, girls in the low and moderate CVH groups had high health factor scores despite low health behavior scores. Conclusion Most 6 to 8-year-old children in Beijing were found to have relatively good CVH, and optimization of children s CVH status can be achieved by promoting healthier lifestyles and monitoring health factors, especially among boys.

Objective: To explore the association of body fat mass and distribution indices including fat mass percentage (FMP), visceral fat area (VFA) and percentage of trunk fat mass (%TFM) with blood pressure in children to inform early management of blood pressure in children. Methods: Based on the Beijing Child Growth and Health Cohort in Shunyi District, lifestyle questionnaire survey, baseline and follow up physical examination were conducted among children from October to November 2018 and September 2020. Bioelectrical impedance analysis (BIA) was used to measure the body composition, and 1 098 participants with completed data were finally included. Results: Both body fat indices and blood pressure increased with age in boys and girls. For FMP, VFA, and %TFM, no significant differences presented between sex at baseline, while FMP, VFA, and %TFM were significantly higher in boys than girls at follow up ( t=2.73, 3.76, 3.41, P <0.01). Before and after adjusting for age, height and lifestyles or not, linear mixed effect models showed longitudinal associations existing between body fat indices and blood pressure in both boys and girls ( β=0.64-3.48, P <0.05). The association coefficients of body fat indices with systolic blood pressure were ranked as %TFM>FMP>VFA in both boys and girls. The association coefficients of body fat indices with diastolic blood pressure were ranked sequentially as FMP>%TFM>VFA in boys, and VFA>FMP>%TFM in girls. Conclusion Longitudinal associations are observed between body fat indices and blood pressure in children. Primordial prevention of high pressure should pay attention on body fat distribution.

Sample preparation is considered as the bottleneck step in bioanalysis because each biological matrix has its own unique challenges and complexity.Competent sample preparation to extract the desired analytes and remove redundant components is a crucial step in each bioanalytical approach.The matrix effect is a key hurdle in bioanalytical sample preparation,which has gained extensive consideration.Novel sample preparation techniques have advantages over classical techniques in terms of accuracy,automation,ease of sample preparation,storage,and shipment and have become increasingly popular over the past decade.Our objective is to provide a broad outline of current developments in various bioanalytical sample preparation techniques in chromatographic and spectroscopic examinations.In addition,how these techniques have gained considerable attention over the past decade in bioanalytical research is mentioned with preferred examples.Modern trends in bioanalytical sample preparation techniques,including sorbent-based microextraction techniques,are primarily emphasized.
