Objective: To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents. Methods: Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents. Results: The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01). Conclusions Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

Objective:To investigate the impact of blood pressure outcomes on the risk of arteriosclerosis in non-hypertensive populations.Methods:This study was a retrospective cohort study. All data were derived from Kailuan Cohort. Non-hypertensive individuals who completed two brachial-ankle pulse wave velocity (baPWV) measurements between January 2014 and December 2019 (using the first measurement as the baseline and the second as the follow-up) were enrolled, and clinical data such as blood pressure and baPWV were collected. According to the blood pressure level at baseline and follow-up, participants were divided into new-onset hypertension group (no hypertension at baseline but diagnosed at follow-up) and non-hypertension group (no hypertension at both baseline and follow-up). Multiple linear regression and multivariate logistic regression were used to analyze the impact of new-onset hypertension on arteriosclerosis progression. Subgroup analysis further classified participants into six blood pressure transition categories: normal-maintained, normal-to-high-normal, normal-to-hypertensive, high-normal-to-normal, high-normal-maintained, and high-normal-to-hypertensive groups. Multivariate logistic regression analysis was used to assess the impact of different blood pressure outcomes on arteriosclerosis progression.Results:A total of 7 049 participants were enrolled, with the age of (40.45±9.04) years, including 3 645 males (51.71%). There were 800 cases in the new-onset hypertension group and 6 249 individuals in the non-hypertension group. During follow-up, arteriosclerosis occurred in 2 154 cases (30.56%). Multivariable linear regression analysis revealed a positive correlation between new-onset hypertension and baPWV levels. The baPWV in the new-onset hypertension group was significantly higher by 63.94 cm/s compared to the non-hypertension group ( β=63.94, P<0.01). Additionally, the risk of arteriosclerosis in the new-onset hypertension group was 2.09 times that of the non-hypertension group ( OR=2.09, 95% CI: 1.77-2.46, P<0.01). Subgroup analysis revealed significantly higher arteriosclerosis risks in normal-to-high-normal ( OR=1.65, 95% CI 1.38-1.98, P<0.01), normal-to-hypertensive ( OR=2.47, 95% CI 1.70-3.59, P<0.01), high-normal-maintained ( OR=1.50, 95% CI 1.21-1.86, P<0.01), and high-normal-to-hypertensive groups ( OR=2.86, 95% CI 2.20-3.73, P<0.01) than normal-maintained group, except for a non-significant difference in high-normal-to-normal group ( OR=0.95, 95% CI 0.74-1.20, P>0.05). Conclusion:Blood pressure outcome in non-hypertensive populations is closely related to arteriosclerosis risk. Progression to or maintenance of high-normal blood pressure or higher levels substantially increases arteriosclerosis risk, while regression from high-normal to normal blood pressure shows no significant increase in arteriosclerosis risk.

Objective:To investigate the effect of p38MAPK signaling pathway mediating progesterone regulation on IL-8 protein secretion by decidual stromal cells(DSCs)on early spontaneous miscarriage.Methods:IHC and Western blot were applied to detect protein expressions of p38MAPK and p-p38MAPK in decidual tissues of miscarriage group and control group.Human DSCs in early pregnancy were isolated in vitro and cultured to be treated with different concentrations of progesterone(0.01 μmol/L,0.1 μmol/L,1 μmol/L and 10 μmol/L),with ELISA measuring IL-8 protein secretion from DSCs and Western blot measuring protein expressions of p38MAPK and p-p38MAPK in DSCs.After treatment with p38MAPK inhibitor SB203580,IL-8 protein secretion was detected by ELISA in progesterone+inhibitor group,progesterone group and control group.Results:Protein expression of p-p38MAPK in decidual tissues of miscarriage group was significantly higher than that of control group(P=0.002 3).Protein secretion of IL-8 in DSCs of 0.01 μmol/L progesterone group was lower than that of control group(P=0.027 6),protein expression of p-p38MAPK in DSCs of 0.1 μmol/L proges-terone group was lower than that of control group(P=0.025 3),IL-8 protein expression was significantly lower than that in control group(P=0.007 0),and protein expressions of both IL-8 and p-p38MAPK from DSCs in 1 μmol/L and 10 μmol/L progesterone groups were significantly lower than those in control group(P=0.003 2,P=0.001 9;P=0.002 2,P=0.001 3).IL-8 protein secretion in proges-terone+p38MAPK inhibitor group was further reduced compared to progesterone group(P=0.046 6).Conclusion:Abnormal activation of p38MAPK signaling pathway is involved in early spontaneous miscarriage,and progesterone may down-regulate IL-8 expression in DSCs by inhibiting p38MAPK phosphorylation to correct early spontaneous miscarriage caused by Th1/Th2 cytokine imbalance.

BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).

Conclusion:Blood pressure outcome in non-hypertensive populations is closely related to arteriosclerosis risk. Progression to or maintenance of high-normal blood pressure or higher levels substantially increases arteriosclerosis risk, while regression from high-normal to normal blood pressure shows no significant increase in arteriosclerosis risk.

Objective:To investigate and compare the clinical outcomes of the arterial pre-occlusion technique(APOT) and the traditional technique in the surgery of locally advanced pancreatic cancer with arterial involvement after conversion therapy.Methods:This is a retrospective cohort study. The clinical data of 145 patients with locally advanced pancreatic cancer with arterial involvement admitted to the Department of Hepato-Biliary-Pancreatic Surgery of the First Hospital Affiliated to Naval Medical University,from January 2020 to December 2022 were retrospectively analyzed. All patients completed neoadjuvant therapy for tumors, and the feasibility of radical surgical treatment was determined by a multidisciplinary collaborative team evaluation before surgery. According to whether the intraoperative artery was pre-occluded, 145 patients were divided into two groups, including 28 cases in the APOT group(16 males, 12 females, aged (59.0±9.4) years), and 117 cases in the routine surgery group(76 males, 41 females, aged (55.1±8.2) years). To ensure comparability of baseline data between the APOT group and the routine surgery group, a 1∶2 match was performed using the propensity score matching method, and the caliper value was 0.006 45. The t-test,the Mann-Whitney U test, χ2 test or Fisher′s exact test were used to compare the data between the two groups,respectively. Results:After matching the propensity score,there were 28 cases in the APOT group and 56 cases in the routine surgery group. There were no significant differences in gender,age,preoperative comorbidities,preoperative body mass index,surgical approaches,chemotherapy regimen,stereotactic body radiation therapy ratio,tumor markers,and type of invaded artery between the two groups (all P>0.05).The arterial occlusion time M(IQR) in the APOT group was 7.0(3.8)minutes(range:3 to 15 minutes),and no ischemic manifestations were observed in the distal target organs that blocked blood vessels after surgery. The operation time was (170.3±57.7)minutes in the APOT group and (235.0±80.2)minutes in the routine surgery group,and the difference was statistically significant ( t=-3.800, P<0.01). The APOT group also experienced less intraoperative blood loss(650(588)ml vs. 800(600)ml; U=1 026.500, P=0.021). No significant differences were found between the groups in combined vein resection and reconstruction,celiac trunk resection,early postoperative complications, readmission rates at 30 days,and postoperative length of stay(all P>0.05). Extra-arterial dissection was performed in all patients,with arterial resection and reconstruction in 3 cases: 2 cases in the APOT group(1 case involving the superior mesenteric artery and 1 case involving the common hepatic artery) and 1 case in the routine group(involving the common hepatic artery). Postoperative abdominal bleeding occurred in 4 cases,with 3 cases in the routine group,1 case in the routine group. The R0 resection rate was 85.7%(24/28) in the APOT group and 80.4%(45/56) in the routine group,without significant differences between the groups( P=0.763). The median overall survival time was 27.6 months for the APOT group and 22.5 months for the routine group,while the median disease-free survival was 11.7 months and 16.8 months,respectively,with no significant differences between the two groups( P=0.532, P=0.927). Conclusion:The arterial pre-occlusion technique can be used for extra-arterial dissection in patients with locally advanced pancreatic cancer involving the arteries,reducing surgery time and intraoperative blood loss.

Objective:To explore the relationship between intestinal microbiomes and asthenospermia.Methods:This was a retrospective case control study. A total of 32 men with asthenospermia and 30 normal men (named control group) were included. The subjects were recruited from Department of Andrology of Shenyang Jinghua Hospital from January 2021 to June 2021. Basic information was collected, semen quality was tested, abundance of intestinal bacteria in feces was detected using 16S rDNA full length assembly sequencing technology (16S-FAST).Results:In patients with asthenospermia, the total sperm count [112.22×10 6 (79.13×10 6, 179.76×10 6)], forward progressive motility rate [22.93% (16.71%, 28.02%)], non-forward progressive motility rate [5.60% (3.98%, 7.62%)] were significantly lower and immobile sperm rate [72.19% (65.27%,78.92%)] was significantly higher than those of control group [166.76×10 6 (110.17×10 6, 262.79×10 6), P=0.022; 42.37% (35.21%, 57.88%), P<0.001; 8.82% (6.18%,11.14%), P=0.001; 50.88% (33.33%, 56.24%), P<0.001], and there were no significant differences in age and body mass index between the two groups (all P>0.05). The participating population can be divided into enterotype 1 (Bacteroide enterotype) and enterotype 2 (Prevotella enterotype). There was no significant difference in α diversity between asthenospermia group and control group in two enterotypes (all P>0.05). In the population with enterotype 2, β diversity analysis clearly separated the microbiome of men with asthenospermia and healthy controls, and the abundance of Proteobacteria phylum, Clostridium sp., Ruminococcus bromii, Phocea massiensis, C. disporicum, Tyzzerella sp. Marseille_P3062, Howardella ureilytica, C. perfringens, and C. sp. BG-C151 species were more abundant in men with asthenospermia compared with control group [linear discriminant analysis (LDA)>2]; while in the population with enterotype 1, β diversity analysis could not separate the microbiome of men with asthenospermia and non-asthenospermia men ( P>0.05). In addition, KEGG analysis showed that in the population with enterotype 2, thiamine metabolism PATH ko00730 pathway, which was closely related to differential bacteria, was significantly less abundant in asthenospermia group than in control group (LDA>2). Conclusion:The intestinal microbiome and KEGG functional pathways differed significantly between asthenospermia and normozoospermia in population with enterotype 2, while there was no difference in the enterotype 1 population. Changes in intestinal microbiome may have an impact on sperm motility in specific populations.
