Objective To analyze the prevalence status of cardiometabolic risk factor (CMRF) and its aggregation among workers engaged in new forms of employment. Methods A total of 5 429 new employment workers (including couriers, online food delivery workers, and ride hailing drivers) who underwent health medical examinations at a tertiary hospital in Beijing City were selected as the research subjects using the judgment sampling method. Data on waist circumference, blood pressure, blood glucose, and blood lipid levels were collected to analyze their CMRF [central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced high-density lipoprotein cholesterol (HDL-C)] and their aggregation (with ≥ 2 of the above 5 risk factors) status. Results The detection rates of central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced HDL-C were 61.2%, 38.2%, 29.5%, 40.9% and 22.6%, respectively. The detection rates of CMRF aggregation was 57.8%. The result of multivariable logistic regression analysis showed that male, age ≥45 years, smoking, overweight, and obesity were risk factors for CMRF aggregation (all P<0.05). Conclusion The detection rate of CMRF and its aggregation among workers with new forms of employment in Beijing City is relatively high. Targeted prevention and control efforts should be strengthened for high-risk populations, especially males, workers aged ≥45 years, smokers, and those who are overweight or obese.

OBJECTIVE: To investigate the effect of laparoscopic high ligation of spermatic cord vein in patients with chronic prostatitis and varicocele prostatitis. METHODS: A total of 90 varicocele patients were selected from January 2016 to December 2020, including 33 patients with chronic prostatitis. Changes of white blood cell count, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score and serum testosterone level in the expressed prostate secretion (EPS) were observed before and after the operation of laparoscopic high ligation of spermatic vein. RESULTS: All patients were followed up three months after the surgery. There was no significant difference in the white blood cell counts in EPS, NIH-CPSI score, and serum testosterone level in patients with varicocele-only who underwent high ligation surgery after the operation. However, the white blood cell count in the EPS of patients with chronic prostatitis was lower than that before 3 months of operation ( ［12.39±4.23］×109/L vs ［21.36±5.05］×109/L). The NIH-CPSI score was significantly lower than that before operation ( ［12.71±6.21］ vs ［26.76±8.43］). And the serum testosterone level was higher than that before operation (［4.34±1.77］ng/ml vs ［2.36±1.05］ng/ml). CONCLUSION Laparoscopic high ligation of the spermatic vein in patients with chronic prostatitis and varicocele could effectively reduce the number of white blood cells in the EPS, boost the level of serum testosterone and improves symptoms of chronic prostatitis.

OBJECTIVE: To explore and verify the effect and potential mechanism of Brucea javanica Seed Oil Emulsion Injection (YDZI) and Shengmai Injection (SMI) on peripheral microcirculation dysfunction in treatment of gastric cancer (GC). METHODS: The potential mechanisms of YDZI and SMI were explored through network pharmacology and verified by cellular and clinical experiments. Human microvascular endothelial cells (HMECs) were cultured for quantitative real-time polymerase chain reaction, Western blot analysis, and human umbilical vein endothelial cells (HUVECs) were cultured for tube formation assay. Twenty healthy volunteers and 97 patients with GC were enrolled. Patients were divided into surgical resection, surgical resection with chemotherapy, and surgical resection with chemotherapy combining YDZI and SMI groups. Forearm skin blood perfusion was measured and recorded by laser speckle contrast imaging coupled with post-occlusive reactive hyperemia. Cutaneous vascular conductance and microvascular reactivity parameters were calculated and compared across the groups. RESULTS: After network pharmacology analysis, 4 ingredients, 82 active compounds, and 92 related genes in YDZI and SMI were screened out. β-Sitosterol, an active ingredient and intersection compound of YDZI and SMI, upregulated the expression of vascular endothelial growth factor A (VEGFA) and prostaglandin-endoperoxide synthase 2 (PTGS2, P<0.01), downregulated the expression of caspase 9 (CASP9) and estrogen receptor 1 (ESR1, P<0.01) in HMECs under oxaliplatin stimulation, and promoted tube formation through VEGFA. Chemotherapy significantly impaired the microvascular reactivity in GC patients, whereas YDZI and SMI ameliorated this injury (P<0.05 or P<0.01). CONCLUSIONS YDZI and SMI ameliorated peripheral microvascular reactivity in GC patients. β-Sitosterol may improve peripheral microcirculation by regulating VEGFA, PTGS2, ESR1, and CASP9.

Dendrobium moniliforme (D. moniliforme) is a traditional medicinal herb widely cultivated in Asia. Flavonoids, one of the largest groups of secondary metabolites in plants, are significant medicinal components in Dendrobium species. Several subgroups of R2R3-MYB proteins have been validated to directly regulate flavonoid biosynthesis. Using PacBio sequencing technology, we assembled a high-quality chromosome-level D. moniliforme genome with a total length of 1.20 Gb and a contig N50 of 3.97 Mb. The BUSCO assessment of genome annotation was 91.4%. By integrating the genome and transcriptome, we identified biosynthesis pathway enzyme genes related to flavonoids, polysaccharides, carotenoids, and alkaloids. A total of 90 R2R3-MYBs were identified in D. moniliforme and classified into 21 subgroups. Studies on the functions of R2R3-MYB transcription factors revealed that R2R3-MYB in SG6 can up-regulate flavonoid biosynthesis. Various validation experiments, including subcellular localization, transient overexpression, UPLC-MS/MS, HPLC, yeast one-hybrid, and dual-luciferase assays, demonstrated that DMYB69 directly up-regulates the expression of enzyme genes involved in flavonoid biosynthesis, increasing the content of flavonoids such as anthocyanin, flavone, and flavonol. Additionally, DMYB44 was shown to directly up-regulate the expression of carotenoid biosynthesis enzyme genes, thereby increasing carotenoid content. This study provides an essential genome resource and theoretical basis for molecular breeding research in D. moniliforme.

Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEO_x-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEO_x) by ester bonds. AEO_x-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEO_x-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEO_x-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEO_x-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Ideological and political education within the curriculum of higher institutions of traditional Chinese medicine （TCM） not only bears the important responsibility of promoting China's outstanding traditional culture but also serves as a vital domain for upholding integrity and innovation in medical education. These institutions must profoundly comprehend the contemporary significance of curriculum-based ideological and political education， clarify its core role in talent cultivation， leverage the distinctive advantages of TCM culture， and promote the organic integration of ideological education and professional training. By reviewing the current situation and development trends of ideological and political education in the curriculum of higher TCM institutions， this paper has analyzed the challenges in teaching design， teachers' ideological and political literacy and competence， and the integration of ideological content with specialized courses， and has proposed implementation strategies such as using TCM culture as a guiding force， strengthening teachers' teaching capacity in ideological and political education， developing distinctive educational resources， and improving evaluation and incentive mechanisms. These strategies aim to effectively enhance the impact of ideological and political education in the new era， fostering well-rounded TCM talents with both moral integrity and professional competence.

Objective:To investigate the clinical effect of free flap transfer with anastomosis of anterior interosseous artery and accompanying veins as the recipient vessels in reconstruction of forearm defects.Methods:A retrospective study was conducted on 5 patients who received free flaps transfers with anastomoses of anterior interosseous artery and accompanying veins in reconstruction of forearm defects with exposed bone and tendon in the Department of Orthopaedics of the First Affiliated Hospital of Anhui Medical University between July 2022 and November 2023. All patients were males, aged 31 to 54 years old with an average age of 41.8 years old. Two patients had defects of dorsal ulnar forearm, 2 of distal forearm and 1 of radial palmar forearm. The defected areas after debridement sized 11.0 cm×4.5 cm-20.0 cm×6.0 cm. Free anterolateral thigh perforator flaps (ALTPF), sized 13.0 cm×6.0 cm-22.0 cm×7.0 cm, were used in 4 patients to reconstruct the forearm defects. A free superficial circumflex iliac artery perforator flap was used in 1 patient with the flap sized at 12.0 cm×5.5 cm. All donor sites were directly sutured. Scheduled postoperative follow up was carried out to evaluate the blood supply to the flaps, texture, appearance, fracture healing and the function of the affected limb, as well as the flap sensation according to the criteria for sensory function of British Medical Research Council (BMRC).Results:All 5 patients had received 4 to 16 (mean 8.8) months of follow-up. All flaps survived completely without necrosis or infection. All flaps were good in colour and texture. The blood supply to hands was good, without a symptoms of coldness and fear of cold of hand. At the final follow-up review, sensation of flaps was assessed according to the criteria for sensory function of BMRC and the sensation of the flaps had recovered to S 2~S 3+. The appearance of flaps was good. Conclusion:Free flap with the anterior interosseous artery and accompanying veins as the recipient vessels in the treatment of forearm defects can achieve satisfactory clinical effect, however, further clinical studies are required.
