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.

In recent years, hybrid brain-computer interfaces (BCIs) have gained significant attention due to their demonstrated advantages in increasing the number of targets and enhancing robustness of the systems. However, Existing studies usually construct BCI systems using intense auditory stimulation and strong central visual stimulation, which lead to poor user experience and indicate a need for improving system comfort. Studies have proved that the use of peripheral visual stimulation and lower intensity of auditory stimulation can effectively boost the user's comfort. Therefore, this study used high-frequency peripheral visual stimulation and 40-dB weak auditory stimulation to elicit steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) signals, building a high-comfort hybrid BCI based on weak audio-visual evoked responses. This system coded 40 targets via 20 high-frequency visual stimulation frequencies and two auditory stimulation frequencies, improving the coding efficiency of BCI systems. Results showed that the hybrid system's averaged classification accuracy was (78.00 ± 12.18) %, and the information transfer rate (ITR) could reached 27.47 bits/min. This study offers new ideas for the design of hybrid BCI paradigm based on imperceptible stimulation.

To investigate the impact of miR-142-5p on intestinal epithelial cells,an expression vector for overexpressing miR-142-5p lentivirus was constructed and administered to mice to observe pathological changes in their colon tissue.The miR-142-5p gene was integrated into the green fluo-rescent lentiviral vector plenti-CMV/TO eGFP-Puro(plenti),and the resulting recombinant vec-tor was named plenti miR-142-5p following confirmation through sequencing.293T cells were transfected with the recombinant plasmid and packaging-assisted plasmid,yielding a packaged miR-142-5p overexpressing lentiviral vector(LV-miR-142-5p).The recombinant lentivirus suspen-sion was collected and concentrated via ultrafast centrifugal precipitation.Virus titer was deter-mined using real-time PCR.The virus suspension was then injected into the tail vein of 6-8-week-old BALB/c mice,after which their colonic tissues were dissected for HE staining and microscopic observation.The results showed that miR-142-5p homologous recombination into plenti vector and sequencing results were consistent with the expected sequence.plenti-miR-142-5p was co-transfect-ed with the packaging helper plasmid in 293T cells,and the successful transfection was confirmed based on the green fluorescence expression,and the real-time PCR results showed that the lentiviral titer was 1.23 × 109 IU/mL.Colon tissue slices from infected mice exhibited compromised colon integrity and significant inflammatory response.It was proved that LV-miR-142-5p was suc-cessfully constructed,and miR-142-5p caused damage to intestinal epithelial cells of mice.

Breast cancer remains a substantial threat to women's health and is one of the most prevalent malignant tumors in women.Because breast cancer onset is closely associated with female physiological characteristics,this article proposes that breast cancer be classified as a"women's miscellaneous diseases"and that its treatment be explored from this perspective.Drawing from Chapter 8 on Golden Chamber of Prescriptions for Miscellaneous Diseases in Women of Synopsis of Golden Chamber,the initial pathogenesis of breast cancer is associated with"emotional stress,improper lifestyle,deficiency,cold,and stagnation."The fundamental mechanism behind its formation is"blood cold accumulation and hardened masses."Specifically,emotional imbalance and improper lifestyle habits contribute to the combined invasion of the uterus by"deficiency,""accumulated cold,"and"stagnant qi."Over time,"cold-blood stasis accumulates at the uterine ostium,"and the cold and the stasis ascends from the uterus along the thoroughfare and conception vessels,obstructing the breast collaterals.This combination of yang qi stagnation and yin cold congealment,ultimately leads to the development of breast cancer.The treatment principle should focus on"activating yang and dispersing cold."A therapeutic approach centered on Wenjing Decoction combined with Xiaoyao Powder can be adapted based on the stage and type of breast cancer while also considering the dynamic interplay between pathogenic factors and healthy qi,along with shifts in deficiency and excess patterns of disease.By adhering to the principles of consistency and flexibility and integrating disease and syndrome differentiation,the goal is to develop precise and personalized treatment strategies to improve clinical outcomes.

Based on the previous transcriptomic experimental data of Trichinella spiralis(T.spira-lis)in this study,the larval stage specific gene TP12446 was screened and its identity in the ubiq-uitin ligase RNF family was predicted.In the study,bioinformatics methods were used to analyze its physicochemical properties and its activity to lay the foundation for further exploring the func-tion of TP12446 gene.The physicochemical properties and protein structure of TP12446 protein were predicted by bioinformatics.Its ubiquitin ligase activity was also verified by ubiquitination re-actions in vitro.The expression characteristics of TP12446 protein in different stage of T.spiralis infection were analyzed by qPCR and Western blot.Bioinformatics analysis showed that TP12446 protein was composed of 453 amino acids and its molecular weight was 51.48 kDa.The protein had a transmembrane structure and contained signal peptides.The results indicated that it was a secre-tory protein and mainly located in the cytoplasmic membrane.The protein structure analysis re-vealed that the protein contained RING and PA domain,its secondary structure was mainly com-posed of α-helix and irregular crimp and there were 10 B cell epitopes on TP12446 protein.The prediction of glycosylation and phosphorylation sites indicated that TP12446 protein contained 38 potential phosphorylation sites.Results of PPI interaction protein prediction showed that TP12446 protein had strong interaction with Usp8,Tmem37,Otub1,Otub2,Ubox5 and CD151.The results of qPCR and Western blot showed that TP12446 gene expression was the highest in the larva stage of T.spiralis,the activity of ubiquitin ligase was verified by ubiquitination reaction in vitro.TP12446 protein was a secretory hydrophobic protein with E3 ubiquitin ligase activity,which was involved in regulating cell cycle and apoptosis.

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.

Objective:To examine the prevalence of malnutrition and evaluate the impact of nutritional support on clinical outcomes in elderly patients diagnosed with gastric and colorectal cancer.Methods:A retrospective cohort study was conducted, analyzing elderly patients with gastrointestinal tumors who underwent surgical treatment in the general surgery department from January 2019 to June 2020.The Global Leadership Initiative on Malnutrition(GLIM)criteria were utilized to diagnose malnutrition, and the effects of malnutrition and nutritional support on clinical prognosis were investigated.Results:A total of 426 elderly hospitalized patients with gastric and colorectal tumors who underwent surgical treatment were included in this study.This cohort comprised 199 cases of gastric cancer and 227 cases of colorectal cancer, with ages ranging from 65 to 91 years(mean age: 72.05±5.99).According to the GLIM criteria, 43.7%(186/426)of the patients were diagnosed with malnutrition, of which 25.6%(109/426)were moderately malnourished and 18.1%(77/426)were severely malnourished.Among the gastric cancer patients, 73.4%(146/199)were identified as having nutritional risk, with 48.7%(97/199)being malnourished and 22.6%(45/199)experiencing severe malnutrition.In the colorectal cancer group, 63.9%(145/227)were at nutritional risk, 39.2%(89/227)were malnourished, and 14.1%(32/227)had severe malnutrition.Additionally, 60.3%(257/426)of the patients received nutritional support therapy: 25.4%(108/426)received parenteral nutrition(PN), 11.3%(48/426)received enteral nutrition(EN), 23.7%(101/426)received a combination of EN and PN, while 39.7%(169/426)did not receive any nutritional support.Regardless of the presence or degree of malnutrition, patients who received nutritional support had significantly shorter total hospital stays compared to those who did not receive nutritional support, and this difference was statistically significant( t=5.58, 3.69, 2.21, 3.03, all P<0.05). Conclusions:Providing nutritional support to malnourished patients can reduce the length of hospital stay and improve clinical outcomes.

Objective:To explore the clinical characteristics of patients with primary ureteral sarcomatoid carcinoma, thereby enhancing the understanding of the clinical context surrounding this disease.Methods:We report a case of primary ureteral sarcomatoid carcinoma in an elderly patient diagnosed through postoperative pathology at the Fourth Medical Center of the General Hospital of the People's Liberation Army.Additionally, a literature review was conducted to analyze articles related to primary ureteral sarcomatoid carcinoma published both domestically and internationally up to July 2024.This review summarizes and analyzes information regarding the clinical manifestations, diagnosis, treatment, and prognosis associated with this condition.Results:A total of 20 articles were reviewed, encompassing 24 cases of primary ureteral sarcomatoid carcinoma.Among the patients, 17 were older than 60 years, and when combined with the cases presented in this review, a total of 18 cases involved patients over the age of 60.Of these, 66.7%(12/18)were male, with a median age at diagnosis of 65 years.The reported cases often exhibited no clinical manifestations in the early stages; however, as the disease progressed, common urinary symptoms emerged, including frequency, urgency, pain, or painless hematuria, occurring throughout the ureteral course.The lesions were predominantly located in the left ureter(17 cases), which frequently exhibited dilation with effusion.Pathologic examination revealed the presence of microscopic spindle cells.Surgical treatment was administered to 20 patients, of whom 9 did not experience recurrence or metastasis during the follow-up period, while 7 cases resulted in mortality.Conclusions:Primary ureteral sarcomatoid carcinoma is a rare malignant tumor of the ureter.Its clinical manifestations are generally regarded as non-specific, making pathological examination the gold standard for diagnosis.Immunohistochemical and imaging studies can assist in the diagnostic process.The current preferred treatment modality is surgical resection, while first-line therapies that combine chemotherapy with immunotherapy and targeted therapy have been shown to enhance tumor control.
