Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10
/L vs preoperative 3.07×10
/L, P<0.001), with significant upregulation of CD11b (7.30×10
/L vs preoperative 3.05×10
/L, P<0.001) and CD54 (7.15×10
/L vs preoperative 2.99×10
/L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10
/L vs preoperative 1.12×10
/L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10
/L vs preoperative 1.12×10
/L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Background Lead smelting workers are exposed to mixed heavy metals such as lead (Pb) and cadmium (Cd). However, the specific associations and molecular mechanisms by which their combined exposure induces genetic damage remain unclear. Objective To clarify the association between combined Pb-Cd exposure and genetic damage and to explore the possible biological mechanisms through occupational epidemiological investigations and animal experiments. Methods (1) Population study: A cross-sectional study was conducted on 374 lead smelting workers in northern China. Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect urinary levels of 8 metals including Pb and Cd, and graphite furnace atomic absorption spectroscopy (GFAAS) was used to quantify blood levels of Pb and Cd. The cytokinesis-block micronucleus assay (CBMN) was used to assess genetic damage. Poisson regression was used to analyze the association between metal exposure and micronucleus rates. (2) In vivo experiment: Thirty SD rats were randomly assigned to five groups: control (pure water), Pb (300 mg·L−1 lead acetate), Cd (50 mg·L−1 cadmium chloride), combined exposure (Pb + Cd), and resveratrol intervention (Pb + Cd + 50 mg·L−1 resveratrol). After 8 weeks of ad libitum drinking water exposure, liver pathology, oxidative stress indicators [reactive oxygen species (ROS), reduced glutathione (GSH), oxidized glutathione (GSSG), malondialdehyde (MDA), catalase (CAT), and superoxide dismutase (SOD)], genetic damage (Comet assay and γ-H2AX) were evaluated. Furthermore, cell cycle distribution, apoptosis rates, and mRNA expression of DNA damage response (DDR), DNA repair, and apoptosis-related genes were measured. Results (1) The geometric mean (GM, 95%CI) of urinary Pb and Cd were 14.69 (13.14, 16.51) µg·L−1 and 2.11 (1.90, 2.33) µg·L−1, respectively; the blood Pb and Cd levels were 117.10 (105.59, 129.87) µg·L−1 and 4.55 (4.23, 4.89) µg·L−1, respectively among the 374 workers. The mean micronucleus rate was (1.64±0.081) ‰, with significantly higher rates in males (1.65±0.083) ‰ than females (1.53±0.334) ‰ (U=4.166, P=0.041). All Pb and Cd biomarkers were positively correlated with micronucleus rate (FR>1, P<0.05), with a significant interaction effect observed between Pb and Cd (FR>1, P<0.05). (2) In rats, co-exposure to Pb and Cd caused liver tissue damage and inflammatory infiltration. Significant increases were observed in lymphocyte ROS; GSSG and MDA in lung tissue increased, while GSH and CAT activity decreased. Comet assay indicators and γ-H2AX levels were significantly elevated. Co-exposure induced S-phase arrest and increased apoptosis. mRNA levels of DDR (ATM, ATR, Chk2, and P53) and pro-apoptotic genes (Bax and Caspase-3) were upregulated, while the anti-apoptotic gene Bcl-2 and DNA repair genes (BRCA1, BRCA2, RAD51, RAD52, and CtIP) were downregulated. Two-way ANOVA confirmed synergistic effects on GSSG, Comet assay indicators, and ATR/Chk2 mRNA expression. Conclusion Occupational co-exposure to Pb and Cd synergistically induces genetic damage. This damage is mediated by oxidative stress and DNA damage, which activates the DDR pathway and inhibits the expression of DNA repair genes, ultimately leading to cell cycle arrest and apoptosis.

This paper summarizes professor WANG Shouchuan's clinical experience in treating childhood absence epilepsy based on the theory of "five zang (脏) organs storing the spirit". It is believed that dysfunction of the five zang organs in storing the spirit is the key pathogenesis of childhood absence epilepsy, proposing that the fundamental therapeutic principle is regulating the spirit by tonifying the five zang organs. Treatment is performed based on differentiation of heart, liver, spleen, lung, and kidney epilepsy. For heart epilepsy, the treatment focuses on harmonizing qi and blood and regulating heart spirit, with Yangxin Anshen Decoction (养心安神汤) or Daochi Ningshen Decoction (导赤宁神汤) selected according to deficiency or excess syndrome. For liver epilepsy, the treatment aims to subdue wind-yang and calm liver spirit, using Bugan Zhenhun Decoction (补肝镇魂汤) or Gouma Qianhun Decoction(钩麻潜魂汤) based on deficiency or excess syndrome. For spleen epilepsy, the treatment concentrates on resolving phlegm-turbidity and restoring spleen thought, employing Guipi Yangyi Decoction (归脾养意汤) or Changyu Huatan Decoction (菖郁化痰汤) in line with deficiency or excess syndrome. For lung epilepsy, the treatment focuses on expelling exogenous pathogens and consolidating lung corporeal soul, applying Yuping Gupo Decoction (玉屏固魄汤) or Xiebai Anpo Decoction (泻白安魄汤) according to deficiency or excess syndrome. For kidney epilepsy, the treatment aims to strengthen the primordial qi and replenish kidney will, with Dihuang Yuanzhi Decoction (地黄远志汤). The self-made Dingxian Powder (定痫散) is used dynamically throughout the course, emphasizing the flexible application of decoctions, pills and syrupsis.

Objective:
To investigate the assocation of sedentary behavior among college students on psychological health issues, such as depressive, anxiety, and stress symptoms, and to analyze the moderating role of takeaway consumption behavior in the context, in order to provide a scientific basis for reducing emotional symptoms among college students.
Methods:
A stratified cluster sampling method was employed to conduct a questionnaire on 3 427 first year students of a higher education institution in Hefei of Anhui Province from May to June 2021. The study variables included demographic characteristics, sedentary time, takeaway consumption behavior, and emotional (symptoms depressive, anxiety, and stress symptoms). The Spearman correlation analysis was used to analyze the association between variables, and linear regression analysis was used to analyze the association between takeaway consumption behavior and depressive, anxiety and stress symptoms among college students with sedentary time.
Results:
Both sedentary time and takeaway consumption behavior were positively correlated with depressive, anxiety and stress symptoms among college students ( r =0.10, 0.10, 0.10; 0.10, 0.11, 0.11, all P <0.05). The results of linear regression analysis showed that the interaction term between takeaway consumption behavior and sedentary time was positively correlated with symptoms of depressive, anxiety, and stress symptoms among college students (depression: β =0.04, anxiety: β =0.04, stress: β =0.04, all P <0.05). The results of the simple slope test demonstrated that regardless of the level of takeaway consumption behavior, sedentary time was positively correlated with the depressive symptoms of college students; compared with low takeaway consumption behavior, high takeaway consumption behavior ( β=0.77, P <0.01) enhanced the association between sedentary time and depressive symptoms among college students. In addition, under the condition of high takeaway consumption behavior, sedentary time was positively correlated with the anxiety and stress symptoms of college students (anxiety: β =0.64; stress: β =0.71, both P <0.01); while under the condition of low takeaway consumption behavior, sedentary time was not related to the anxiety and stress symptoms of college students ( β =0.17, 0.22, both P >0.05).
Conclusions
Sedentary behavior is related to a the emotional symptoms of depressive, anxiety, and stress among college students. Takeaway consumption behavior may exacerbate this impact.

Objective:To evaluate the accuracy and safety profile of a novel cuboid orientation-guided frontal horn ventriculostomy technique in patients with large hemispheric infarction (LHI).Methods:It was conducted a retrospective cohort study of 48 consecutive LHI patients who underwent the innovative ventriculostomy procedure between time period. Primary outcomes included procedural accuracy (success rates, catheter positioning) and safety indicators (complication rates).Results:All the punctured ventricles were small or of normal size. The success rate of puncture was 100%, the success rate of one-time puncture was 87% (42/48), and the average number of puncture was 1.13 times per case. The ratio of well-positioned tube heads was 87.5% (42/48). The actual angle of the inward deviation of the puncture ranged from -2o to 5o, with an average of 0o±0.3o. The depth of puncture was 7.0-8.0 cm ( 7.3±0.3) cm. The incidence of bleeding around the puncture path was 1.3% (2/48 ) and no massive bleeding occurred. At the 6-month follow-up, one case (2.94%) among the 34 survivors had epilepsy.Conclusions:The cuboid orientation-guided frontal horn ventriculostomy technique demonstrates exceptional procedural accuracy and an excellent safety profile in LHI patients, with high first-pass success rates (87.5%) and minimal complications (4.2% minor hemorrhage). These findings support its clinical adoption for this patient population.

Objective:To investigate the clinical efficacy of a self-detachable single-J internal stent drainage tube in the laparoscopic primary suture of the common bile duct for hepatolithiasis.Methods:Clinical data of 36 patients with hepatobiliary duct stones who underwent laparoscopic common bile duct primary suture combined with self-detached single J-type internal stent drainage at the First Affiliated Hospital of Xiamen University from April 2022 to April 2025 were retrospectively analyzed, including 17 males and 19 females, aged (54.3±8.7) years. All 36 patients underwent choledochoscopic stone extraction, primary common bile duct suture, and drainage with the self-expelling single-J internal stent. Total bilirubin, aspartate transaminase, and alanine transaminase before and 3 days after operation, as well as operation time, intraoperative blood loss, postoperative hospital stay, postoperative complications (bile leakage, cholangitis, intestinal obstruction, and stent retention), and stent expulsion time were collected.Results:All 36 patients successfully underwent the operation. Total bilirubin, aspartate transaminase, and alanine transaminase 3 days after operation showed significant improvement compared to preoperative levels (all P<0.05). The operation time was (86.5±22.6) min, intraoperative blood loss was 34.2 (13.7, 56.8) ml, and the postoperative hospital stay was (6.6±1.8) days. All single-J internal stents were spontaneously expelled via the anus between 6 and 21 days postoperatively, with the expulsion time of (10.7±2.1) days. No single J-type internal stent drainage tube was displaced into the bile duct in all cases, and there were no complications such as intestinal obstruction, bile leakage, cholangitis, or residual internal stent drainage tube. Conclusion:The self-detachable single-J internal stent drainage tube has been applied in the laparoscopic primary suture of the common bile duct for patients with hepatolithiasis, which demonstrated a good safety and effectiveness.

In the context of further promoting the construction of an integrated healthcare service system,traditional quantitative indicators for measuring continuity of care may have limitations.The analysis of domestic and foreign studies on the mortality rate associated with service continuity measured by quantitative indicators shows that a lack of correlation or even an inverse correlation between continuity of care and mortality.This phenomenon may be attributed to the fact that the indicators have only single dimension and unable to capture the multidimensional nature of continuity of care.Based on these findings,some ideas are proposed for the improvement of the indicators,which contribute to thoughts and suggestions on the quantitative measurement of continuity of care.
