China now has the largest number of people living with diabetes worldwide. To address such a burden, the Healthy China 2030 initiative and subsequent Healthy China Initiative-Diabetes Prevention and Treatment Action Plan(2024-2030)were launched. A shift from " disease-centred" approach to " health-centred" approach and from treatment to prevention is the core of diabetes management in China. Various regions have formed some characteristic prevention and control models with local features in their long-term diabetes prevention and control work, such as the " Community Three-in-One" management model, hospital-community integrated prevention and control model, " Three Doctors Shared Management" model, and family doctor model. Based on the description of the current situation of diabetes prevention and control in China, this article elaborates on the diabetes prevention and control model, key measures, and practical effects in Bao′an District, Shenzhen. It aims to introduce the practices and reflections on diabetes prevention and control in Bao′an, Shenzhen, and provide experiential reference for diabetes prevention and control in other areas.

Objective:To compare the clinical efficacy and safety of nanomicroneedle- versus ultrasound-mediated delivery of tranexamic acid for the treatment of melasma.Methods:A prospective, randomized, controlled study was conducted. Patients with melasma were collected from the Department of Dermatology, Guangzhou Dermatology Hospital from March 2023 to May 2024, and divided into a nanomicroneedle group (receiving nanomicroneedle-mediated delivery of tranexamic acid) and an ultrasound group (receiving ultrasound-mediated delivery of tranexamic acid) using the random number table method. Both groups underwent the treatment once a week for a total of 8 sessions. At week 12, outcomes including melasma area and severity index (MASI) scores, treatment response rates, VISIA brown spot scores, pain scores, and adverse reactions were evaluated and compared between the two groups. Statistical analyses were carried out using two-independent-sample t test, Mann-Whitney U test, and chi-square test. Results:A total of 80 patients with melasma were included, with 40 in each group. In the nanomicroneedle group, the patients were aged 40.35 ± 7.39 years (range: 25 - 55 years), with the disease duration being 8.45 ± 4.77 months (range: 1 - 16 months) ; in the ultrasound group, the patients were aged 40.25 ± 7.76 years (range: 25 - 55 years), and their disease duration was 10.45 ± 5.07 months (range: 2 - 17 months) ; there were no significant differences in ages or disease duration between the two groups (both P > 0.05). At week 12, both groups demonstrated reduced MASI scores compared to baseline scores, and the MASI scores were significantly lower in the nanomicroneedle group ( M[ Q1, Q3]: 5.80[4.20, 9.35]) than in the ultrasound group (8.65[5.70, 10.80], Z = 2.50, P = 0.012). The overall response rate was significantly higher in the nanomicroneedle group (97.5%, 39/40) than in the ultrasound group (55.0%, 22/40; χ2 = 19.95, P < 0.001). The lateral facial VISIA brown spot scores were also significantly lower in the nanomicroneedle group (left side: 126.18 ± 36.54 points; right side: 138.50 ± 40.76 points) than in the ultrasound group (left side: 142.37 ± 32.40 points; right side: 157.13 ± 39.59 points; t = -2.10, -2.07, P = 0.039, 0.041, respectively). In the nanomicroneedle group, the pain scores were 4.12 ± 1.47 points, and varying severity of adverse reactions such as erythema, edema and dryness occurred after operation, all of which resolved spontaneously within 48 hours. No marked adverse reactions were observed in the ultrasound group. Conclusion:Nanomicroneedle-mediated delivery of tranexamic acid demonstrated superior clinical efficacy and favorable safety profiles compared to the ultrasound-mediated delivery, providing more options for the treatment of melasma.

OBJECTIVE To investigate the efficacy and safety of the interleukin-1(IL-1)receptor antagonist anakinra in the treatment of refractory adult onset Still's disease(AOSD),and provide more real-world evidence and practical experience for the treatment of AOSD with this drug.METHODS A retrospective analysis was conducted on the diagnosis and treatment process of a patient with AOSD complicated with dermatomyositis who received anakinra;systematically searched for relevant literature on the treatment of AOSD with anakinra in Chinese and English databases such as CNKI,PubMed,Medline,etc.,and conduct literature review on its efficacy and safety.RESULTS The patient in this case had poor treatment with multiple traditional drugs and was considered to have AOSD combined with dermatomyositis.After being admitted to the hospital and treated with a combination therapy of anakinra and glucocorticoids for several days,the patient's clinical symptoms and inflammatory indicators significantly improved,and no serious adverse drug reactions occurred.Pharmacists designed specialized pharmaceutical monitoring pathways and conduct regular follow-up after discharge.After discharge,the patient took medication regularly,and the condition was maintained and relieved;during this period,there was redness and swelling at the injection site which resolved on its own without any other obvious discomfort.Literature review showed that anakinra could increase the response rate and remission rate of AOSD patients,and significantly reduce the dosage of glucocorticoids;adverse events were mainly injection site reactions,with a low overall risk of infection and good safety;however,there was a significant difference in the treatment course,and there was currently no unified plan.CONCLUSIONS Anakinra is an efficient and safe biological agent for treating AOSD,which can rapidly induce and maintain disease remission.For AOSD patients,clinical consideration may be given to using IL-1 antagonists to reduce glucocorticoid dependence,while strengthening long-term medication monitoring.

Bacillus mycoides JA20-1 was screened and identified as a biocontrol bacterium with a high capacity for producing volatile organic compounds(VOCs) in the laboratory. This strain had significant inhibitory effects on various postharvest disease pathogens in crops, such as Botrytis cinerea, as well as soil-borne disease pathogens in ginseng, such as Sclerotinia ginseng. In order to accelerate its industrialization process, in this study, single-factor experiments and response surface optimization methods were used. The fermentation medium and fermentation conditions in the shake flask of strain JA20-1 were systematically optimized by using cell production volume as the response variable. Meanwhile, the biocontrol effect of JA20-1 on B. cinerea of ginseng during the storage period was evaluated by using the method of fumigation in a dry dish in vitro. The results indicated that the optimal fermentation medium formulation for strain JA20-1 was as follows: 1% yeast paste, 1% soluble starch, 0.25% K_2HPO_4·3H_2O, and 0.2% NaCl. The optimal fermentation conditions in the shake flask were vaccination size of 3%, culture volume of 50 mL in a 250 mL Erlenmeyer flask, pH of 6.2, fermentation temperature of 34 ℃, shaking speed of 180 r·min~(-1), and incubation time of 18 hours. The bacteria count in the fermentation broth under these conditions reached 2.17 × 10~8 CFU·mL~(-1), which was 6.58 times higher than before. The average control efficacy of the fermentation broth on Botrytis cinerea of ginseng under in vitro fumigation reached 61.70% and 84.04% respectively, when 20 mL and 30 mL per dish were used. The research provided theoretical support and technical foundation for the development and utilization of Bacillus mycoides JA20-1 and the biocontrol of soil-borne diseases in ginseng and postharvest diseases in crops.

Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.
