The occupational population in China faces increasingly complex health risks, with a growing burden of chronic diseases and multimorbidity. Based on data from the China Health and Nutrition Survey (CHNS), this special column systematically analyzed trends in dietary structure, nutrient intake, and metabolic abnormalities among different occupational groups from 1989 to 2018, revealing the combined effects of occupational categories and dietary behaviors on multimorbidity risk. The findings highlight that rational dietary patterns and healthy behaviors are key modifiable factors. It is recommended to leverage workplaces as platforms for nutritional interventions and behavioral improvement, thereby improving health literacy among the occupational population. Furthermore, the establishment of a multi-sectoral health promotion mechanism is recommended to guide dietary optimization and lifestyle transformation, contributing to chronic disease prevention and occupational health protection.

Background With China's socioeconomic development, significant lifestyle changes have occurred among occupational groups, leading to alterations in cardiovascular metabolic risk factors. However, few studies have examined the secular trends of these risk factors in China's working population. Objective To analyze the trends in cardiovascular metabolic risk factors among the occupational population in nine provinces of China from 2009 to 2018, and to explore the associations between different occupational types and these risk factors, along with their clustering patterns, thereby providing evidence for targeted interventions. Methods This study utilized data from the China Health and Nutrition Survey (CHNS) in 2009, 2015, and 2018. The dataset covered 13274 employed individuals aged 18-59 years. Only participants with complete blood test results and physical measurement data were included in the final analysis. The average annual percentage change (AAPC) in the positive rates of risk factors was calculated using Joinpoint regression to analyze temporal trends. Multinomial logistic regression and binary logistic regression models were employed to examine the cross-sectional associations between occupational types (categorized as white-collar workers, agricultural workers, blue-collar workers, service workers, and others) and nine cardiovascular metabolic risk factors and their clustering (defined as having ≥2 risk factors) in 2018. Results A total of 8451 participants were included. From 2009 to 2018, significant increasing trends (AAPC>0, P<0.05) were observed for overweight, obesity, central obesity, borderline elevated triglycerides (TG), borderline elevated to elevated total cholesterol (TC), borderline elevated low-density lipoprotein cholesterol (LDL-C), elevated blood pressure and hypertension, diabetes. The most rapid increases were found for obesity (AAPC=6.07%, 95%CI: 3.42%, 8.88%), hypertension (AAPC=4.10%, 95%CI: 0.62%, 7.77%), and central obesity (AAPC=3.27%, 95%CI: 1.24%, 5.36%). The clustering rate of risk factors increased from 62.3% in 2009 to 73.2% in 2018 (AAPC=1.87%, 95%CI: 1.02%, 2.73%). The cross-sectional analysis in 2018, after adjusting for confounders, showed that compared with white-collar workers, blue-collar workers had a significantly lower risk of overweight (OR=0.67, 95%CI: 0.48, 0.95), central obesity (OR=0.65, 95%CI: 0.45, 0.92), and borderline high TG (OR=0.54, 95%CI: 0.35, 0.82). In contrast, agricultural workers had a higher risk of hypertension (OR=1.76, 95%CI: 1.14, 2.72). Conclusion Between 2009 and 2015, the burden of most cardiometabolic risk factors increases significantly among the Chinese occupational population, with the rate of increase slowing by 2018. Risks vary across occupational types, among which blue- collar workers report lower target outcomes. Targeted interventions focusing on the rapidly increasing risk factors and high-risk occupational groups are recommended.

End-stage liver disease (ESLD) covers the end-stage of acute and chronic liver diseases, mainly involving decompensated cirrhosis, various types of liver failure, and advanced liver cancer. Hepatocyte transplantation has shown promise in treating ESLD, but its clinical application is hampered by the shortage of donor hepatocytes. Cell therapy, an emerging effective treatment for ESLD, faces the same limitation due to scarce hepatocyte availability. Hepatocyte-like cells (HLCs), which are terminally differentiated cells, can be induced from both stem cells and somatic cells. As HLCs exhibit the morphology and function of primary hepatocytes, they offer a promising supplementary source of hepatocytes for cell therapy. First, we provide a background for the differentiation and maturation of primary hepatocytes. Subsequently, based on the current insights into the molecular pathways that regulate hepatocyte differentiation in vivo, we describe a strategy for establishing HLC derived from either stem cells or somatic cells. The key characteristics of these HLCs are also detailed. Furthermore, HLC offers therapeutic potential for liver failure, and HLC-based liver organoids and bioartificial liver systems have demonstrated the ability to provide liver functions, offering an innovative approach to treating various types of ESLD. Despite their promise, challenges such as efficiency in differentiation and functional maturation need to be addressed to improve the clinical application of HLCs. This review discusses these advancements and outlines the therapeutic potential and current challenges of HLC therapy for ESLD.

Psychological problems are significant factors that contribute to the occurrence of postoperative complications, reduced quality of life, and prolonged hospital stays. Lung cancer patients who require surgery often experience high psychological stress related to both the disease and the treatment, making them more susceptible to depression and anxiety. Therefore, timely intervention to address these psychological issues is crucial for promoting postoperative recovery and improving patients' quality of life. This paper will review the current status, impact, and interventions for depression and anxiety-related psychological problems in lung cancer surgery patients.

Objective:To evaluate the efficacy of ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia in laparoscopic bariatric surgery.Methods:In this prospective randomized controlled study, 80 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱpatients, aged 18-40 yr, with a body mass index of 30-45 kg/m 2, of cardiac function classification Ⅰ or Ⅱ, who underwent laparoscopic bariatric surgery at the First Affiliated Hospital of Nanjing Medical University from February 2023 to May 2023, were selected and divided into 2 groups ( n=40 each) using a table of random numbers: general anesthesia group (GA group) and subcostal quadratus lumborum block combined with general anesthesia group (SQB+ GA group). Both groups received combined intravenous-inhalational anesthesia. Patients in SQB+ GA group underwent bilateral ultrasound-guided subcostal quadratus lumborum block with 20 ml of 0.375% ropivacaine before anesthesia induction. Oxycodone was administered for analgesia during the post-anesthesia care unit (PACU) stay. Patient-controlled intravenous analgesia with sufentanil and granisetron was used after returning to the ward. When the visual analog scale score >4 within 24 h after surgery, flurbiprofen axetil 50 mg was intravenously given as rescue analgesic. The intraoperative consumption of remifentanil and use of vasoactive drugs were recorded. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded. The tracheal extubation time, PACU stay time, use of oxycodone during PACU stay, and occurrence of hypoxemia after tracheal extubation and occurrence of adverse reactions within 24 h after surgery was also recorded. Arterial blood gas analysis was performed at discharge from PACU. Results:Compared with GA group, the intraoperative consumption of remifentanil was significantly reduced, the usage rate of oxycodone, effective pressing times of patient-controlled analgesia and rate of rescue analgesia were significantly decreased, the PaO 2 and PaCO 2 at discharge from PACU were decreased, the tracheal extubation time and PACU stay time were shortened, and the incidence of hypoxemia after tracheal extubation and postoperative nausea and vomiting was decreased in SQB+ GA group ( P<0.05). Conclusions:Compared with general anesthesia alone, ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia can reduce the intraoperative consumption of opioids, alleviate postoperative pain, and decrease the occurrence of postoperative adverse reactions when used in laparoscopic bariatric surgery.

Objective:To analyze the gallbladder morphology in ultrasound examinations of children with biliary atresia, classify them accordingly, and compare the gallbladder size of different types of patients and healthy infants.Methods:Clinical data of 711 cases with biliary atresia treated at the Department of General Surgery at the Capital Center for Children's Health, Capital Medical University from January 2017 to July 2022 were retrospectively analyzed, including 407 males and 304 females, aged (46.5±26.9) days. Additionally, 106 healthy infants recruited from the same hospital between January 2024 and March 2024 were included in the control group, including 60 males and 46 females, aged (48.5±23.9) days. The gallbladder morphology was classified into four types (A, B, C and D) based on its size and shape on ultrasonography. The long diameter of the gallbladder gradually increased, with its shape gradually approaching normal. The proportions of gender, time of jaundice onset (calculated from birth), total bilirubin, direct bilirubin, γ-glutamyl transferase (γ-GT), gallbladder contraction rate, hepatic portal cyst, and cholangiography were compared among different types. The gallbladder length and width of type D were also compared with those of the healthy control group.Resluts:Among the 711 patients, 123(17.3%) were of type A, 330 (46.4%) were of type B, 112 (15.8%) were of type C, and 146 (20.5%) were of type D. There were no statistically significant differences in the male ratio, the timing of jaundice onset, total bilirubin levels, direct bilirubin levels, or γ-GT levels among the four types of patients (all P>0.05). However, the incidences of combined hepatic portal cysts in type C and D were higher than those in type A and B (all P<0.01). Notably, 68.5% (100/146) of type D patients had a gallbladder contraction rate of ≤25%, lower than the 91.8% (303/330) of type B and 95.5% (107/112) of type C ( χ2=42.41, 29.22, both P<0.001). The success rates of cholangiography for type C and D patients were 75.0% (84/112) and 76.7% (112/146), respectively, both higher than the 11.4% (14/123) for type A and 45.2% (149/330) for type B (all P<0.001). In the healthy control group, the length and width of gallbladder were larger than those in type D patients ( t=10.64, 11.62, both P<0.001). Conclusion:The ultrasonic gallbladder morphology in biliary atresia patients is diverse, and there are no significant clinical differences among the four types. However, there are differences in gallbladder contraction rates and the success rates of gallbladder imaging. The gallbladder length and width of type D patients, with a nearly normal gallbladder morphology, are smaller than those of healthy infants at the same age.

Objective:To observe the effects of moxibustion at Shenshu(BL23)and Zusanli(ST36)on Toll-like receptor 4(TLR4)-myeloid differentiation factor 88(Myd88)signaling pathway-mediated inflammatory factors in the synovial tissue of ankle joints of rats with rheumatoid arthritis(RA),and to explore the molecular and biological mechanisms underlying the anti-inflammatory and analgesic effects.Methods:A total of 24 male Sprague-Dawley(SD)rats were randomly divided into a normal group,a model group,and a moxibustion group,with 8 rats in each group.The RA model was established with exposure to wind,cold,and damp environmental factors,along with Freund's complete adjuvant.After three days of modeling,mild moxibustion was applied to bilateral Shenshu(BL23)and Zusanli(ST36)in the moxibustion group using moxa sticks of 0.9 cm in diameter for 30 min each time,once a day for 14 d.Structural changes in the synovial tissue and cells were then observed using hematoxylin-eosin staining and transmission electron microscopy,while immunohistochemistry analysis was used to detect tumor necrosis factor(TNF)-α,interleukin(IL)-17,IL-1β,and IL-6 levels.Moreover,the protein expression levels of Myd88,TLR4,and transient potential receptor vanilloid type 1(TRPV1)in the synovial tissue were detected using Western blotting,while their mRNA expression levels were detected using reverse transcription-polymerase chain reaction.Finally,the levels of IL-1β,IL-2,IL-6,IL-17A,and TNF-α in rat serum were detected using enzyme-linked immunosorbent assay.Results:Compared to the normal group,the model group exhibited notable pathological synovial tissue damage,along with significantly higher IL-1β,IL-6,and TNF-α levels(P<0.01)and a slightly higher IL-17 content(P>0.05).Furthermore,the Myd88,TLR4,and TRPV1 protein and mRNA expression levels and serum IL-1β,IL-2,IL-6,IL-17A,and TNF-α levels were all significantly higher in the model group than in the normal group(P<0.01).Compared to the model group,the moxibustion group exhibited a lower degree of synovial tissue pathological damage,along with significantly lower IL-1β,IL-6,and TNF-α levels(P<0.05 or P<0.01)and a lower IL-17 content without statistical significance(P>0.05).Moreover,the Myd88,TLR4,and TRPV1 protein and mRNA expression levels,and serum IL-1β,IL-2,IL-6,IL-17A,and TNF-α levels were all significantly lower in the moxibustion group than in the model group(P<0.01 or P<0.05).Conclusion:Mild moxibustion at Shenshu(BL23)and Zusanli(ST36)can effectively inhibit TLR4-MyD88 signaling pathway-mediated inflammatory factor expression in the synovial tissue of ankle joints of RA rats.Furthermore,the effect of moxibustion on synovial tissue inflammation in RA rats may be attributed to TRPV1 channel activation.

ObjectiveTo investigate the possible mechanism of action of Xibining Formula （膝痹宁） for cartilage damage in knee osteoarthritis （KOA） through the cyclic guanosine-adenosine monophosphate synthase （cGAS）- stimulator of interferon genes （STING） signaling pathway. MethodsFifty C57BL/6J mice were randomly divided into five groups （10 per group）， sham operation group， KOA model group， low-dose Xibining Formula group， high-dose Xibining Formula group， and high-dose Xibining Formula + agonist group. The KOA models were constructed using the destabilization of the medial meniscus （DMM） method in all groups but the sham surgery group. Two weeks after surgery， the low- and high-dose Xibining Formula groups were administered Xibining Formula at doses of 3.58 g/（kg·d） and 14.32 g/（kg·d） respectively via gavage. The high-dose Xibining Formula + agonist group received 14.32 g/（kg·d） of Xibining Formula via gavage followed by an intraperitoneal injection of Vadimezan （DMXAA） at 25 mg/kg. The sham surgery group and the KOA model group mice were given an equivalent volume of normal saline at 5 ml/（kg·d） via gavage， once daily for four consecutive weeks. Serum levels of tumor necrosis factor-alpha （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） were measured by ELISA； pathological changes in cartilage tissue were observed using hematoxylin-eosin （HE） staining and Safranin O-Fast Green staining. Pathological changes were scored according to the Mankin scoring system； the levels of cartilage tissue matrix regulation-related indicators such as matrix metalloproteinase 3 （MMP3）， matrix metalloproteinase 13 （MMP13）， a disintegrin and metalloproteinase with thrombospondin motifs 5 （ADAMTS）， type-Ⅱ collagen （CⅡ） and aggregated proteoglycan （Aggrecan）， and also cGAS-STING pathway-related protein and mRNA expression levels were detected by Western blot and qPCR methods. ResultsCompared with the sham surgery group， the KOA model group showed severe cartilage edge destruction， significantly increased Mankin scores， significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan， and significantly increased protein and mRNA expression levels of cGAS， STING， MMP3， MMP13， and ADAMTS5 （P＜0.01）. Compared with the control group， serum level of IL-6， IL-1β， TNF-α in all the intervented groups decreased （P＜0.01）， while compared with high-dose Xibining Formula group， level of IL-6， IL-1β， and TNF-α in low-dose Xibining Formula group and high-dose Xibining Formula + agonist group increased （P＜0.01）. Compared with the KOA model group， all the intervention groups exhibited alleviated cartilage pathological changes， signi-ficantly reduced Mankin scores， significantly increased protein and mRNA expression levels of COLⅡ and Aggrecan， and significantly decreased protein and mRNA expression levels of cGAS， STING， MMP3， MMP13， and ADAMTS5 （P＜0.01）. Compared with high-dose Xibining Formula group， high-dose Xibining Formula + agonist group showed cartilage edge destruction， significantly increased Mankin scores， significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan， and increased protein and mRNA expression levels of cGAS， STING， MMP3， MMP13， and ADAMTS5 （P＜0.01）. ConclusionXibining Formula may improve KOA cartilage damage by inhibiting the cGAS-STING signaling pathway， decreasing matrix degradation-related proteins， and elevating matrix composition-related proteins.

Background: The transvenous approach to the treatment of cerebral arteriovenous malformation (AVM) is difficult and requires strict blood pressure and blood flow control; however, the cure rate is very high. Appropriate blood pressure control techniques can greatly benefit these patients.Case: A 55-year-old male patient was found to have an aneurysm complicated with a cerebral AVM (length: 2.0 cm, width: 1.6 cm, height: 1.2 cm). Aneurysm embolization was considered for the first-stage surgery and transvenous AVM embolization for the second-stage surgery. Rapid ventricular pacing (RVP) provided a stable blood flow environment for the surgery, which was completed successfully. Conclusion RVP can thus provide an ideal condition for the embolization of cerebral AVM through the transvenous approach and can be a viable surgical option.

Background and purpose:The microphthalmia-associated transcription factor(MITF)plays a complex role in melanoma pathogenesis and progression.It is known to regulate multiple processes both in melanocytes and melanoma cells.While numerous studies have explored MITF in cutaneous melanoma(CM),research in acral melanoma(AM)is still limited.This study retrospectively analyzed the correlation between MITF expression and clinical,pathological characteristics and prognosis in AM patients,providing a basis for prognosis evaluation and personalized treatment plan formulation for patients.Methods:Patients who underwent primary resection of AM at Fudan University Shanghai Cancer Center from March 2008 to February 2022 were included.All surgical samples were diagnosed by clinical histopathology and used to construct the tissue microarray(TMA).This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(approval number:2203-ZZK-69-3).Cutting complete tissue microarray and evaluating MITF expression levels by immunohistochemistry(IHC)staining were carried out.The results were independently assessed and scored by three pathologists.Clinical and pathological data were collected from the hospital's electronic medical record system,and each patient's data was matched to their corresponding tissue sample on the chip.Patients were stratified into two groups based on MITF expression levels.Statistical analyses were performed to assess differences in clinical,pathological characteristics and survival outcomes between these two groups.Results:A total of 137 AM patients were included.MITF expression was significantly associated with T stage,N stage,American Joint Committee on Cancer(AJCC)stage,clark level,sentinel lymph node status,and presence of ulceration.Among these,N stage and ulceration were independent risk factors for high expression of MITF after adjusting for confounding factors.Survival analysis showed that AM patients with high MITF expression or higher T stage were associated with shorter disease-free survival(DFS).Patients with high MITF expression showed no significant difference in overall survival(OS)between observation or cytokine therapy and adjuvant immune checkpoint inhibitor(ICI)therapy,whereas those with low MITF expression derived significant survival benefits from ICI treatment.Conclusion:A higher N stage or the presence of ulceration indicates high MITF expression in tumor cells,with high MITF levels serving as a warning signal for early recurrence,metastasis,and even death.Patients with low MITF expression could receive improved OS with early adjuvant ICI therapy.MITF could not only serve as an auxiliary diagnostic marker for melanoma but also provide a basis for clinical prognosis assessment and the formulation of personalized treatment plans.
