Objective: To quantitatively assess the health risk of preservatives from beverages around primary schools in Anshun City, and to provide scientific basis for precise food safety supervision. Methods: From December 2023 to July 2024, 602 beverage samples were randomly collected from within 100 meters of 19 primary schools in Anshun City. The content of benzoic acid, sorbic acid, and dehydroacetic acid was detected according to GB 5009 series standards. Combined with children s physiological parameters (body weight 30 kg, daily intake 0.15 L), the Hazard Quotient (HQ) and Hazard Index (HI) models were used to evaluate health risks. Results: The total detection rate of preservatives from beverages around primary schools was 63.0%, and the total over limit rate was 9.0%. The detection rate of preservatives in flavored beverages was the highest (72.6%), and the highest over limit rate of preservatives in special purpose beverages was the highest (17.2%). The single preservative HQ (benzoic acid up to 0.47 ) and mixed HI (up to 0.55) of all samples were below 1(safety threshold). However, the HQ value of benzoic acid in flavored beverages (0.47) was 2.9 times that of sorbic acid (0.16), contributing significantly to health risk. Sensitivity analysis showed that if the daily consumption increased to 0.3 L, the HI value of flavored beverages would rise to 1.11, exceeding the safety threshold. Enterprise scale analysis showed that the exceedance rate of special purpose beverages in large enterprises reached 30.0%, while micro enterprises, accounting for a dominant market share (52.2%), constituted the main source of children s daily exposure to their products. Conclusions The overall health risk of perservatives in beverages sold near primary schools in Anshun City is controllable, but there is a noticeable risk of gradient. The risk of children’s exposure to preservatives through beverage consumption should not be ignored.

Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

Wumei Pills, a classic traditional Chinese medicine(TCM) formula, are widely used in the treatment of biliary ascariasis and diarrhea. In recent years, studies have shown that Wumei Pills have advantages in the treatment of type 2 diabetes mellitus(T2DM), while there are no relevant reports that systematically evaluate the efficacy of Wumei Pills in the treatment of T2DM. This study addresses this issue by systematically evaluating the efficacy and safety of Wumei Pills, aiming to provide an evidence-based basis for clinical practice. PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, and VIP were researched for the randomized controlled trial(RCT) involving Wumei Pills for the treatment of T2DM that were published from inception to September 2024. RevMan 5.3 was used for the Meta-analysis of the data. A total of 18 RCTs were included, with a total of 1 437 patients. Meta-analysis produced the following results.(1)Treatment group outperformed control group in terms of overall response rate(RR=1.28, 95%CI[1.14, 1.43], P<0.000 1), fasting blood glucose(FPG)(WMD=-0.69, 95%CI[-0.93,-0.46], P<0.000 01), two-hour postprandial plasma glucose(2hPG)(WMD=-0.74, 95%CI[-1.17,-0.31], P<0.000 7), glycated hemoglobin(HbA1c)(WMD=-0.39, 95%CI[-0.60,-0.18], P=0.000 3), high-density lipoprotein(HDL)(WMD=0.38, 95%CI[0.28, 0.48], P<0.000 01), and body mass index(BMI)(WMD=-1.41, 95%CI[-2.40,-0.42], P=0.005).(2)The two groups had comparable effects regarding total cholesterol(TC)(WMD=-0.53, 95%CI[-1.13, 0.08], P=0.09) and low-density lipoprotein(LDL)(WMD=-0.25, 95%CI[-0.56, 0.06], P=0.12).(3)Triglycerides(TG)(WMD=-0.28,95%CI [-0.59,0.03],P=0.08), sensitivity analysis showed potential reduction effect(WMD=-0.20,95%CI[-0.36,-0.04],P=0.01). Occurrence of adverse drug reaction(RR=0.43,95%CI [0.23,0.80],P=0.007), sensitivity analysis showed significant disappearance(RR=0.56,95%CI[0.26,1.22],P=0.14), suggesting that the efficacy of treatment group was not better than that of control group. The results indicate that the treatment of T2DM with Wumei Pills is greatly related to the improvement of glucose metabolism, lipid metabolism, and clinical efficacy. The findings provide a basis for clinical application of Wumei Pills in treating T2DM, while the conclusion remains to be verified by clinical studies with higher quality.

As the important source of bone cells, osteoblasts are involved in bone formation and repair, and play a key role in maintaining bone balance. If the osteogenic differentiation process in vivo is disrupted, a variety of bone-related diseases may occur. Natural products, which have a wide range of sources, a wide variety of physiological activities, and few toxic side-effects, have been found in recent years to be able to regulate osteoblast differentiation. Based on the sources of natural products, this paper reviews the intervention of natural products from plant, animal and microbial sources on osteogenic differentiation, aiming to provide a theoretical basis for natural products in the treatment of bone diseases.
