Objective: To explore the association between maternal lipid levels during pregnancy and the risk of overweight and obesity in offspring at 3 years of age, providing scientific evidences for the prevention and control of childhood obesity. Methods: A total of 2 432 mother-child pairs with maternal lipid tests during pregnancy and offspring s physical growth data at 3 years of age were included from the Borin in Guangzhou Cohort Study up to September 2021. Lipid indicators, including high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol(LDL-C), triglycerides (TG), and total cholesterol (TC), were measured at 13-19 +6 weeks (mid pregnancy) and 32-39 +6 weeks (late pregnancy). Children s body mass index (BMI) Z score were calculated according to the World Health Organization s growth standards for children under 5 years old. The lipid Z score were divided into four quartiles: Q 1, Q 2, Q 3 and Q 4. Linear regression was used to analyze the relationship between maternal lipid levels during pregnancy and offspring’s BMI Z score at 3 years of age. Poisson regression with a robust error variance was employed to evaluate the association between maternal lipid levels during pregnancy and the at risk of overweight and obesity in offspring at 3 years of age, after adjusting for maternal age at conception, education level, parity, pre pregnancy BMI and gestational diabetes mellitus. Results: There was a statistically significnt difference in the detection rate of overweight and obesity risk among children with different mothers s pre pregnancy BMI ( χ 2=22.85, P <0.05). Linear regression analysis showed that TG levels in late pregnancy were positively related to BMI Z score ( β=0.10, 95%CI=0.02-0.18, P <0.05). Poisson regression with a robust error variance indicated that, compared with the Q 1 group of TC, the Q 4 group of TC in mid pregnancy was associated with an increased risk of overweight and obesity in offspring at 3 years of age ( RR=1.59, 95%CI =1.04-2.44); compared with the Q 1 group of TG, the Q 4 group of TG during late pregnancy increased the risk of overweight and obesity in offspring at 3 years of age ( RR=1.79, 95%CI =1.02-3.12) (both P <0.05). Conclusions Maternal serum TC level during mid pregnancy can increase the risk of overweight and obesity in offspring at 3 years of age. Maternal serum TG levels during late pregnancy is positively correlated with BMI and the risk of overweight and obesity in offspring at 3 years of age.

Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies. Based on the immunomodulatory capability of CAR-T cells, efforts have turned toward exploring their potential in treating autoimmune diseases. Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases, covering a range of subtypes such as systemic lupus erythematosus, multiple sclerosis, among others. CAR-T therapy holds promise in mitigating several shortcomings, including the indiscriminate suppression of the immune system by traditional immunosuppressants, and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints. By persisting and proliferating in vivo, CAR-T cells can offer a tailored and precise therapeutics. This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases, incorporating innovations well-studied in the field of hematological tumors, aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.

Objective:To investigate the predictive value of serum levels of C-C motif chemokine ligand 21 (CCL21) and C-X-C motif chemokine receptor 3 (CXCR3) for stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to No.215 Hospital of Shaanxi Nuclear Industry from July 2020 to December 2023 were prospectively included. Serum CCL21 and CXCR3 test results and general clinical data at admission were collected using the hospital electronic medical record system. The independent influencing factors of SAP were identified through multivariate logistic regression analysis, and the predictive value of serum CCL21 and CXCR3 levels for SAP were analyzed by receiver operating characteristic (ROC) curves. Results:A total of 150 patients with AIS were enrolled, including 91 males (60.67%), aged 61.48±7.92 years. Among them, 41 patients (27.33%) developed SAP during hospitalization. There were significant differences in serum CCL21 and CXCR3 levels, National Institutes of Health Stroke Scale score, Glasgow Coma Scale score, invasive mechanical ventilation, length of hospital stay, and the proportion of patients with hypertension and diabetes between the SAP group and the non-SAP group (all P<0.05). Multivariate logistic regression analysis showed that serum CCL21 (odds ratio [ OR] 1.022, 95% confidence interval [ CI] 1.006-1.039; P=0.006) and CXCR3 ( OR 1.036, 95% CI 1.018-1.054; P<0.001) levels were the independent risk factors for SAP. ROC curve analysis showed that serum CCL21 and CXCR3 levels had good predictive power separately for SAP. The areas under the curve was 0.730 (95% CI 0.634-0.825) and 0.807 (95% CI 0.721-0.892), respectively. The combined prediction of the two showed an area under the curve of 0.881 (95% CI 0.819-0.943). Conclusion:The patients with AIS generally have higher levels of serum CCL21 and CXCR3. The levels of serum CCL21 and CXCR3 are closely associated with SAP, and both of them have a good predictive effect on SAP alone or in combination.

Objective:To evaluate the efficacy of SedLine Brain Function Monitor-guided total intravenous anesthesia for children undergoing hypospadias surgery.Methods:This was a randomized controlled trial. A total of 161 children, aged 1-10 yr, with American Society of Anesthesiologists Physical Status classification ⅠorⅡ, scheduled for elective hypospadias surgery, were divided into SedLine group (S group, n=83) and control group (C group, n=78) using a random number table method. In group S, 95% spectral edge frequency (SEF 95) was maintained at 14-18 Hz, and the patient state index (PSI) was maintained at 25-50 during surgery. In group C, mean arterial pressure was maintained at 60-80 mmHg, and heart rate was maintained at 80-110 beats/min during surgery. PSI and SEF 95 were recorded before induction (T 1), at 0, 5 and 10 min after intubation (T 2-4), at the beginning of surgery (T 5), at 30 min and 1 h after surgery (T 6, 7), and at the end of surgery (T 8). The anesthetic duration, operation time, time from withdrawal to extubation, postanesthesia care unit duration, consumption of propofol and remifentanil, intraoperative adverse events, 5-point Likert scale scores, and emergence delirium scores were recorded. Results:Compared to C group, the total anesthesia time, time from withdrawal to extubation and postanesthesia care unit duration were significantly shortened, the consumption of propofol for both induction and maintenance was reduced, the PSI at T 5-8, SEFL 95 at T 2-6, and SEFR 95 at T 2-8 were increased, and the incidence of intraoperative body movement and incidence of emergence agitation were decreased in S group ( P<0.05). Conclusions:SedLine Brain Function Monitor-guided total intravenous anesthesia provides better efficacy when used for the children undergoing hypospadias surgery.

It is a classic formula for treating gastric distension recommended by doctors of later ages. This article systematically reviews the clinical application and basic experimental progress of Chaihu Shugansan in the treatment of functional dyspepsia. In modern clinical practice， Chaihu Shugansan and its modified formulas are used to treat functional dyspepsia， and they can be applied in combination with other formulas （Si Junzitang， Jinlingzisan， Zhizhuwan， etc.）， western medicine （domperidone tablets， deanxit， Saccharomyces boulardii， etc.）， traditional Chinese medicine （TCM） acupuncture and other therapies. The results of clinical studies have shown that Chaihu Shugansan and its modified formulas can significantly reduce the Hamilton depression scale （HAMD） score， Hamilton anxiety scale （HAMA） score， and TCM syndrome score， ameliorate the symptoms， improve the quality of life， and decrease the recurrence rate. The experimental pharmacological studies have demonstrated that Chaihu Shugansan can inhibit the autophagy of Cajal interstitial cells， regulate the endoplasmic reticulum stress signaling pathway， and modulate the brain-gut peptide level to improve the gastrointestinal motility. Chaihu Shugansan can inhibit the expression of 5-hydroxytryptamine in the colon tissue and reduce the abdominal withdrawal reflex （AWR） score to improve visceral hypersensitivity. Furthermore， Chaihu Shugansan can lower the levels of pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-α to repair duodenal mucosal inflammation. In addition， it can regulate intestinal flora to maintain intestinal flora balance. The main active ingredients such as saikosaponin， paeoniflorin， hesperidin， and naringin in Chaihu Shugansan can exert anti-inflammatory， antioxidant， and antimicrobial effects.

Objective: To investigate the effect of root canal therapy (RCT) on inflammatory cytokines level in peripheral blood, anxiety, and depression in patients with pulpitis. Methods : A total of 155 patients with pulpitis admitted to the Stomatology Hospital of the Fourth Military Medical University from June 2021 to June 2022 were treated with root canal therapy. Another 155 persons who received health examinations during the same period were selected as the control group. The Generalized Anxiety Disorder-7 (GAD-7) scores and the Patient Health Questionnaire-9 (PHQ-9) scores of the two groups were compared. The GAD-7, PHQ-9 and pain scores of the test group before treatment and 3 and 6 weeks after treatment were compared. Pain was assessed with a visual analog scale (VAS). Inflammatory cytokine [interleukin-8 (IL-8), interleukin-1 β (IL-1β), tumor necrosis factor-α (TNF-α), c-reactive protein (CRP)] levels in the test group before treatment and 3 and 6 weeks after treatment were compared. Results : The GAD-7 and PHQ-9 scores in the test group were higher than those in the control group before treatment (P<0.05). The GAD-7 and PHQ-9 scores in the test group at 3 and 6 weeks after treatment were lower than those before treatment (P<0.05); there was no significant difference between the GAD-7 and PHQ-9 scores at 3 and 6 weeks after treatment(P>0.05). The pain scores of the experimental group at 3 and 6 weeks after treatment were lower than those before treatment (P<0.05), and the pain scores 6 weeks after treatment were lower than those at 3 weeks after treatment (P<0.05). The levels of IL-8, IL-1β, TNF-α and CRP in the peripheral blood of the experimental group were lower 3 and 6 weeks after treatment than before (P<0.05), and the levels of IL-8 and IL-1β in the peripheral blood at 6 weeks after treatment were significantly lower than at 3 weeks after treatment (P<0.05). The levels of TNF-α and CRP in the peripheral blood at 6 weeks after treatment were not significantly different from those at 3 weeks after treatment (P>0.05). Conclusion The peripheral blood of patients with pulpitis has a high level of inflammatory cytokines, and the patients suffer from obvious anxiety and depression. Root canal therapy can relieve their anxiety and depression by reducing their level of inflammatory cytokines in peripheral blood.

Objective:To observe the effect of medium-length intravenous catheter infusion on the intima and hemodynamics of the implanted blood vessel, in order to early detect the asymptomatic ultrasound imaging manifestations of indwelling blood vessel injury in patients, and observe the occurrence of catheter-related complications.Methods:Totally 105 patients who had medium-length venous catheters inserted through the upper arm in Huangshi Central Hospital from July to December 2021 were selected by random sampling. A self-control study was adopted. According to the time of data collection, they were divided into pre-catheterization group and the post-extubation group. Color Doppler ultrasonography was used to observe the image morphology, blood flow velocity, and blood flow of the vein intima at the outlet of the catheter tip before catheterization and after extubation, and to monitor the incidence of catheter-related complications. Among the 105 patients, 5 cases dropped out, and the effective sample size was 100 cases.Results:Among the 100 patients, before catheterization and after extubation, the vascular intima at the indwelling catheter tip showed no damages such as roughness and thickening; there was no statistically significant difference in venous blood flow velocity and the blood flow at the catheter tip before and after catheter extraction ( P>0.05) . There were 5 cases (4.76%, 5/105) of catheter-related complications. Conclusions:Medium-length intravenous catheter infusion of hyperosmolar parenteral nutrition solution does not significantly affect the morphology and hemodynamics of the intima of the implanted vessel, the implanted vessel is not damaged, and no serious complications such as catheter-related thrombosis and bloodstream infection occur, which achieve relatively safe clinical outcomes.

In the face of a serious occupational disease prevention and control situation, the lack of efficient supervision and regulation methods has become a prominent contradiction. This paper reviewed the progress and application of occupational health grading and classification supervision methods for employers in China in recent years, and analyzed the characteristics and limitations of selected methods. The grading and classification supervision methods have gradually developed from considering only inherent health risk of occupational disease hazards, to considering both inherent attributes of occupational disease hazards and exposure duration. Some regional authorities introduced trial measures for grading and classification of occupational health supervision by embracing exposure level of an occupational disease hazard of interest, associated outcome severity, and occupational health management situation of targeted employers. In October 2022, the National Disease Control and Prevention Bureau issued the Notice on Carrying out Pilot Work of Occupational Health Classification Supervision and Law Enforcement, which further promoted the establishment of a differentiated occupational health supervision model. Grading and classification of occupational health supervision can improve the supervision efficiency of public health administration departments and promote employers to fulfill the main responsibility of occupational disease prevention and control.
