To standardize the clinical application of oral Chinese patent medicines （CPMs）， and address the safety issues arising from their dosage form characteristics， irrational clinical use， and the lack of targeted pharmacovigilance systems， the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines， aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China （2019 revision）， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences， led a drafting group comprising 18 institutions. After multiple rounds of expert interviews， literature retrieval， evidence screening， and extensive solicitation of opinions， the Guidelines were registered internationally. Systematic standardization focused on safety monitoring， risk identification， assessment， control， and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring， known risks， and potential risks， compared to non-oral CPMs. Then， risk control measures were proposed， including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs， the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine （TCM）， which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions， pharmaceutical manufacturers， and regulatory authorities.

The Solomon four-group design， a critical method for improving internal validity in clinical research， can reduce bias and control the interference of Hawthorne effects and pretest sensitization on research results， which offers unique advantages in evaluating complex intervention outcomes. This paper systematically outlined the core framework and key points of statistical analysis of the Solomon four-group design， summarized its applications in clinical research at home and abroad， explored its advantages and limitations， and discussed the potential value in traditional Chinese medicine （TCM） clinical trials. It is believed that the Solomon four-group design can help distinguish between testing effects and intervention effects in TCM clinical studies， and reduce the bias in the evaluation of subjective indicators. Meanwhile， given the complexity of the Solomon four-group design and the particularity of TCM clinical research， it is proposed that future TCM clinical studies should focus on using psychological scales， know-ledge， attitude， and behavior measurements， and other similat evaluations as endpoints. It also advocates strengthening interdisciplinary collaboration to provide new methodological paths for TCM clinical research.

Background The Inner Mongolia Autonomous Region is a vast area with a wide array of ecological environments, resulting in considerable regional variations in air pollution characteristics. Current research is limited by a scarcity of systematic, region-wide studies and risk assessments. Objective To assess the health risks associated with inhalation exposure to nine heavy metal and metalloid elements in atmospheric fine particulate matter (PM_2.5) for the population of the Inner Mongolia Autonomous Region. Methods From the 10th to the 16th of each month throughout 2023, atmospheric PM_2.5 samples were collected at designated monitoring sites in 12 leagues (cities) across the Inner Mongolia Autonomous Region to analyze the characteristics and trends in concentration. The health risk assessment model developed by the United States Environmental Protection Agency was employed to evaluate both the non-carcinogenic and carcinogenic risks associated with the heavy metal elements beryllium (Be), cadmium (Cd), chromium (Cr), hydrargyrum (Hg), plumbum (Pb), manganese (Mn), and nickel (Ni) and the metalloid elements stibium (Sb) and arsenic (As). Results In 2023, a total of 1206 valid PM_2.5 samples were analyzed from the Inner Mongolia Autonomous Region. The annual average PM_2.5 concentrations in Inner Mongolia, as well as in the cities of Ordos, Wuhai, and the Alxa League, all exceeded the national limit of 35 μg·m⁻³. The PM_2.5 concentrations across the leagues (cities) exhibited a clear seasonal variation, peaking in winter, followed by spring, and reaching a minimum in summer and autumn. The median PM_2.5 concentration in Ordos throughout the year was higher than that in the other leagues (cities) of the region. Concerning health risks, the non-carcinogenic risks associated with the 9 elements detected in each league (city) were all below 1, indicating acceptable levels. However, the non-carcinogenic risk values for Mn, Cr, and As were relatively high; specifically, Ordos City displayed the highest non-carcinogenic risk values for Mn (7.74×10⁻¹) and Cr (2.97×10⁻²), while Chifeng City recorded the highest value for As (2.34×10⁻³). The carcinogenic risk values for As, Cd, Cr, and Ni fell within the range of 1×10⁻⁹ to 1×10⁻⁵, representing an acceptable level. The health risks varied with age, and the elderly residents faced the highest non-carcinogenic and carcinogenic health risks. Conclusion While the carcinogenic and non-carcinogenic risks from heavy metals and metalloids within atmospheric PM_2.5 in the Inner Mongolia Autonomous Region are generally within acceptable limits, the potential risks that Mn, As, and Cr pose to the health of elderly people warrants particular attention, and Ordos and Chifeng cities exhibit notably higher health risks among other areas. It is recommended that regular, long-term monitoring be conducted, taking into account the specific conditions at monitoring sites across each league (city), and that targeted air quality management strategies be implemented to protect public health.

OBJECTIVE: To explore the method and effectiveness of index finger proximal dorsal island flap supplied by the nutrient vessels of superficial branch of radial nerve for treatment of thumb skin and soft tissue defect. METHODS: Between August 2019 and December 2024, 12 patients with thumb skin and soft tissue defects caused by trauma accompanied by variation of the first dorsal metacarpal artery were treated. There were 8 males and 4 females, aged 19-55 years, with an average age of 32 years. The wound area ranged from 2.2 cm×2.0 cm to 5.5 cm×3.5 cm. The time from injury to operation ranged from 1.5 to 6.0 hours, with an average of 4.5 hours. After thorough debridement, the wound was repaired with a index finger proximal dorsal island flap supplied by the nutrient vessels of the superficial branch of the radial nerve. The flap area ranged from 2.4 cm×2.2 cm to 6.0 cm×4.0 cm. The donor site was repaired with free skin grafting. Regular follow-up was conducted postoperatively to observe the appearance, texture, sensory recovery of the flap, and the condition of the donor site. RESULTS: The operation time ranged from 30 to 72 minutes, with an average of 47 minutes; intraoperative blood loss ranged from 30 to 70 mL, with an average of 46 mL. After operation, partial necrosis occurred at the skin edge of the radial incision on the dorsum of the hand in 1 case, which healed after dressing changes; all other flaps survived uneventfully, with primary wound healing. The skin grafts at the donor sites all survived. All 12 patients were followed up 5-36 months, with an average of 14 months. The appearance and texture of the flaps were good. At last follow-up, the two-point discrimination of the flaps ranged from 4 to 9 mm, with an average of 5.2 mm. According to the functional evaluation criteria for upper limb issued by the Hand Surgery Society of Chinese Medical Association, the results were excellent in 11 cases and good in 1 case. No scar contracture, pain, or joint movement limitation was observed at the donor sites. CONCLUSION For patients with skin and soft tissue defects of the thumb accompanied by variation of the first dorsal metacarpal artery, the index finger proximal dorsal island flap supplied by the nutrient vessels of the superficial branch of the radial nerve can be selected. This method has advantages such as shorter operation time, less intraoperative bleeding, and good postoperative appearance and sensation of the flap.

The paper elucidates the background and conceptual connotations of HeLit-Schools, and analyzes how HeLit-Schools effectively integrate and enhance the health literacy of schools in three aspects: philosophy and core drivers, strategy and method implementation, as well as evaluation mechanisms and standard setting. Furthermore, the paper explores the implications of foreign HeLit-Schools research and practice for China under the context of "Healthy China" construction, as well as the key strategies for Chinese schools in the implementation of HeLit-Schools, aiming to provide a new perspective and theoretical support for Chinese schools to practice the "Healthy China initiative" and strengthen school construction from the perspective of health literacy.

Objective:To investigate the effects and mechanism of exosome (EXO)-loaded kringle V11 (KV11) delivery on corneal neovascularization (CNV).Methods:KV11 was bound to the surface of endothelial cell-derived exosomes by using CP05, an EXO-targeting anchoring peptide, to produce EXO-KV11.The binding efficiency and optimal concentration ratio were determined using the Apogee flow system.A total of 100 8-week-old healthy male SPF grade SD rats were selected, 10 of which were randomly selected as a normal control group without any treatment.The CNV model was established by alkali burn in the other 90 rats, which were randomly divided into three groups, EXO-KV11 group, KV11 group, and normal saline group by the random number table method, with 30 rats in each group.Each group was injected subconjunctivally with 100 μl of EXO-KV11 (25 μg), KV11 (25 μg), or normal saline every other day from the first day after the alkali burn, respectively.The CNV of rats was observed on days 1, 4, 7, and 14 after alkali burn.The CNV area was calculated by ventricular perfusion with fluorescein isothiocyanate-dextran (FITC-dextran) and corneal angiography.The amount of CNV lumen was observed by hematoxylin and eosin staining.The distribution of CD31 in rat corneas was determined by immunohistochemical method.The expression levels of voltage-dependent anion channel 1(VDAC1), endoplasmic reticulum stress, autophagy and apoptosis-associated proteins were detected by Western blot.This study was approved by the Animal Ethics Committee of Peking University People's Hospital (No.20210019). All animal procedures complied with the regulations of the Vision and Ophthalmology Association and the Animal Protection and Use Committee of Peking University.Results:The optimal concentration ratio of KV11 to EXO was 4∶1 and the binding affinity reached up to 87.5% by Apogee flow cytometers.On days 7 and 14 after alkali burn, there were significant differences in CNV area among the four groups ( F=4.613, 15.590; both at P<0.05). On day 7 after alkali burn, the CNV area was smaller in EXO-KV11 group than in KV11 and normal saline groups, with statistically significant differences (both at P<0.05). On day 14 after alkali burn, the CNV area was smaller in EXO-KV11 and KV11 groups than in normal saline group, and smaller in EXO-KV11 group than in KV11 group, showing statistically significant differences (all at P<0.05). The results of quantitative analysis of corneal fluorescence mounts showed that the relative CNV fluorescence area of the normal saline group, KV11 group and EXO-KV11 group were (8.3±1.7)%, (5.2±1.6)%and (3.4±0.7)%, respectively, showing a statistically significant overall comparison difference ( F=11.735, P<0.01). The relative CNV fluorescence area was larger in KV11 and normal saline groups than in EXO-KV11 group, and larger in normal saline group than in KV11 group, showing statistically significant differences (all at P<0.05). On day 14 after alkali burn, massive neovascular lumens were observed in the matrix of the normal saline group.The number of neovascular lumens in KV11 group was smaller than that in normal saline group.The corneal structure appeared normal in EXO-KV11 group, and neovascular lumens were rare.Numerous CD31-positive cells were observed in the corneal stroma of the normal saline group, which formed into lumen structures.The number of lumens surrounded by CD31-positive cells in the corneal stroma was smaller in KV11 group than in normal saline group, and smaller in EXO-KV11 group than in KV11 group.There were significant differences in the relative expression levels of VDAC1, protein kinase R-like endoplasmic reticulum kinase (PERK), p62, cleaved caspase 3 among the four groups ( F=35.960, 8.947, 17.791, 101.168; all at P<0.01). The relative expression levels of VDAC1, PERK, p62, cleaved caspase 3 were higher in EXO-KV11 group than in KV11 and normal saline groups, showing statistically significant differences (all at P<0.001). There was no significant difference in the relative expression of microtubule-associated proteins 1A/1B light chain 3B (LC3B)Ⅱ/LC3BⅠ protein among all four groups ( F=0.445, P=0.727). Conclusions:EXO-KV11 can inhibit CNV more remarkably than KV11.EXO-KV11 inhibits CNV by promoting the expression of VDAC1 and PERK and suppressing the autophagic flux.

Objective:To analyze the correlation between serum calcium levels and the prognosis of survival and renal recovery in patients with acute kidney injury (AKI) accompanied by hypercalcemia.Methods:This retrospective study analyzed the clinical data of patients with AKI accompanied by hypercalcemia admitted to Shanghai General Hospital from December 2015 to August 2022. There were 157 patients included in the study. The observation endpoint was set at discharge, focusing on the patients' survival and renal recovery during this period. Based on their status at discharge, patients were divided into a survival group (116 cases) and a death group (41 cases); and among the survivors, into a renal recovery group (63 cases) and a non-recovery group (53 cases). Continuous variables conforming to normal distribution were expressed as xˉ± s, and the mean comparison between the two groups was performed using an independent sample t-test. Continuous variables not conforming to normal distribution were represented by median (interquartile range) and compared between groups using the Mann-Whitney U test. Categorical variables were expressed as frequency (percentage), and comparisons were made using the chi-squared (χ 2) test or Fisher's exact test, as applicable. The correlation between serum calcium levels and patient outcomes was analyzed using univariate and multivariate Logistic regression. Results:The average age of the study subjects was (68.37±16.28) years, with 97 males (61.78%). The ages in the survival and death groups were (65.39±16.13) years and (76.80±13.67) years, respectively, with 66 males in the survival group and 31 in the death group. The history of malignancy (excluding multiple myeloma) was 37 cases and 23 cases, respectively, and serum albumin levels were (35.41±6.84) g/L and (30.82±5.75) g/L, respectively. Significant Statistical differences were observed in age, gender, history of malignancy (excluding multiple myeloma), and serum albumin were found between the survival and death groups (statistical values: t=4.04, χ 2=4.49, χ 2=7.51, t=3.85; all P<0.05). AIK 1 stage were 33.33%(21/63) and 64.15%(34/53), 2 stage were 36.51%(23/63) and 24.53%(13/34), 3 stage were 30.16%(23/63) and 11.32%(6/34) in the renal recovery and non-recovery groupsrespectively. Serum calcium at discharge in the renal recovery and non-recovery groups were (2.50±0.38) mmol/L and (2.70±0.58) mmol/L, respectively, with mean serum calcium levels of (2.60±0.29) mmol/L and (2.78±0.39) mmol/L, and lowest serum calcium levels of (2.28±0.36) mmol/L and (2.50±0.51) mmol/L, respectively. BNP levels were 118 (64, 283) ng/L and 248 (69, 1 383) ng/L, respectively. Significant differences in AKI stage, serum calcium at discharge, mean serum calcium, lowest serum calcium, and BNP were observed between the two groups (statistical values: χ 2=11.84, t=2.26, t=2.75, t=2.73, U=2.62, all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.062, 95% CI 1.027-1.098, P<0.001), history of malignancy (excluding multiple myeloma) ( OR=3.811, 95% CI 1.623-8.951, P=0.002), and serum albumin ( OR=0.889, 95% CI 0.829-0.953, P=0.001) were independent risk factors for in-hospital mortality of patients; severity of AKI(AKI2 OR=2.984, 95% CI 1.281-6.954, P=0.011, AKI3 OR=5.280, 95% CI 1.863-14.963, P=0.002) and serum calcium level at discharge ( OR=0.813, 95% CI 0.666-0.992, P=0.041) were independent risk factors affecting early renal recovery of patients. Conclusion:Serum calcium level is not associated with the risk of in-hospital mortality in patients with AKI accompanied by hypercalcemia but is related to the prognosis of early renal recovery. Proactively managing serum calcium, along with treatment of the primary malignancy and correction of hypoalbuminemia can help improve the prognosis of these patients.

Objective To explore the effect and mechanism of Baicalein in the treatment of hyperuricemia.Methods The mouse model of hyperuricemia was established by yeast extract combined with potassium oxazinate.The effect and potential mechanism of Baicalein in the treatment of hyperuricemia were studied by biochemical indexes,pathological changes,non-target metabonomics and network pharmacology.Results Baicalein could reduce the contents of serum uric acid,creatinine and blood urea nitrogen,reduce the inflammatory injury of renal tissue,up-regulate the expression level of uric acid excretion protein and down-regulate the expression level of uric acid reabsorption protein.Nine disease-related targets such as BCL2,SIRT1 and XDH were screened by network pharmacology.Six key metabolic pathways including nicotinic acid and nicotinamide metabolism,caffeine metabolism and purine metabolism were screened by metabonomics analysis.Conclusions Baicalein can treat hyperuricemia and reduce renal injury,and its mechanism may be related to the metabolic pathways of nicotinic acid and nicotinamide regulated by SIRT1 and quinolinate.
