OBJECTIVE To investigate the effect of plasma trough concentration of venetoclax and its influencing factors in patients with acute myeloid leukemia (AML). METHODS After 5 days of venetoclax administration, venous blood samples were collected from AML patients before the next dose. Plasma trough concentrations of venetoclax were determined using high-performance liquid chromatography-tandem mass spectrometry. Spearman correlation was used to assess the correlations between venetoclax plasma trough concentration and various parameters (including patients’ general information, venetoclax-related indicators, liver function indicators, kidney function indicators, and blood routine indicators). Multiple linear regression analysis was performed to identify independent factors influencing plasma trough concentration of venetoclax. Using efficacy as dependent variable [complete remission (CR)+partial remission (PR) vs. no remission (NR)], univariate and multivariate binary Logistic regression analyses were conducted to identify factors affecting efficacy. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of venetoclax plasma trough concentration for clinical efficacy (assessed as CR). RESULTS A total of 172 venetoclax plasma trough concentration measurements from 101 patients were included in this study. The median plasma trough concentration of venetoclax was 2.38 (1.18, 3.85) μg/mL; the median sampling time for plasma trough concentration of venetoclax was 10 (7, 15) d; the duration of venetoclax use was (34±12) d. Multiple linear regression analysis showed that alkaline phosphatase ( B =14.65, 95%CI: 5.35-23.95, P =0.002), total bilirubin ( B =-101.71, 95%CI: -197.16 to -6.25, P =0.037), and white blood cell count ( B =-106.84, 95%CI: -187.61 to -26.07, P =0.010) were independent factors influencing plasma trough concentration of venetoclax. Due to patient attrition during treatment, 114 venetoclax plasma trough concentration measurements from 69 patients were included for efficacy evaluation. The results showed that 46 patients (66.7%) achieved CR, 11 patients (15.9%) achieved PR, and 12 patients (17.4%) were NR. Multivariate binary Logistic regression analysis showed that age, hemoglobin, venetoclax plasma trough concentration, hematocrit, and mean corpuscular hemoglobin were independent factors affecting patient efficacy ( P <0.05). ROC curve analysis showed that the cut-off value of plasma trough concentration of venetoclax for predicting patient efficacy (assessed as CR) was 1.68 μg/mL (AUC=0.66, 95%CI: 0.54-0.78, P =0.014). CONCLUSIONS There is considerable inter-individual variability in plasma trough concentration of venetoclax among AML patients. Plasma trough concentration of venetoclax is significantly correlated with alkaline phosphatase, total bilirubin, and white blood cell count. Plasma trough concentration of venetoclax is an independent factor affecting patient’s efficacy, and when the cut-off value for predicting CR is above 1.68 μg/mL, better effects may be achieved.

This paper summarizes Professor WANG Yaoxian's experience in treating diabetic kidney disease (DKD) from the perspective of spleen and stomach based on the "internal heat leading to concretions" theory. It is considered that internal heat leading to concretions constitutes the core pathogenesis of DKD, with the spleen and stomach serving as the source of internal heat; therefore, treatment should be based on regulating the spleen and stomach. In the early stage of DKD, dysfunction of the spleen and stomach leads to the initial generation of internal heat. Common syndrome patterns include gastrointestinal heat accumulation and constrained heat in the liver and stomach, for which modified Gegen Qinlian Decoction (葛根芩连汤) can be used to clear heat bind while modified Dachaihu Decoction (大柴胡汤) is used to clear stomach and soothe liver, respectively. In the middle stage of DKD, weakness of the spleen and stomach results in the initial formation of concretions and conglomerations. Common patterns include spleen deficiency with prevalence of dampness and deficiency of both the spleen and kidney. Treatment emphasizes strengthening the spleen and resolving dampness, raising yang and boosting the stomach with modified Shengyang Yiwei Decoction (升阳益胃汤), or supplementing spleen and boosting kidney, dissipating bind and dispe-ring concretions with modified Shenqi Dihuang Decoction (参芪地黄汤), respectively. In the late stage of DKD, it is characterized by spleen and stomach depletion, and rampant accumulation of turbidity and toxin, and the common syndrome patterns are damp-turbidity obstruction in the middle jiao (焦) and spleen-kidney yang deficiency. Treatment aims to remove turbidity and harmonize the stomach, or to warm the kidney and strengthen the spleen while elimina-ting turbidity, using modified Dahuang Gancao Decoction(大黄甘草汤) and Jupi Zhuru Decoction (橘皮竹茹汤) or modified Baoyuan Decoction (保元汤) and Lizhong Decoction (理中汤), respectively. In clinical practice, appropriate formulas and medications are flexibly selected according to specific syndromes.
5.Study on meal preferences of school aged children based on discrete choice experiment
Chinese Journal of School Health 2025;46(1):45-49
Objective:
To explore the relative importance of different food attributes and levels in food decision making of school aged children, and to understand their meal preferences, so as to provide the evidence for formulating precise intervention strategies for dietary behaviours of school aged children.
Methods:
From May to June 2024, a total of 854 children aged 11 to 15 years old were selected from 2 middle schools (each school in urban and rural areas) in both Hubei Province and Anhui Province by stratified cluster random sampling method to conduct a D-optimal discrete choice experiment. The mixed Logit model was used to analyze children s preference for meal attributes and different levels, and to calculate the relative importance (RI) of attributes and willingness to pay (WTP) in meal choices.
Results:
The included five food attributes had statistical significance on meal choice of school aged children ( P <0.05). The relative importance of food attributes affecting the meal choices of school aged children in descending order were dining mode ( RI =31.26%), food varieties ( RI =30.56%), cooking method( RI =23.84%), taste( RI =8.06%) and price ( RI =6.27%). Among them, school aged children preferred home cooked meals ( β =0.74) (WTP=86.3 yuan),varied foods(grain/tubers+vegetables+fish, meat, eggs and beans) ( β =0.61) (WTP=71.9 yuan), fried/roasted cooking ( β =0.51) and spicy taste ( β =0.33).Price was negatively correlated with meal choices( β =-0.01) ( P <0.05). Based on residential area and body mass index (BMI), the stratified analysis showed that dining mode was highest in the relative importance for rural children with overweight and obese children ( RI =31.28%,34.17%), both of whom preferred home cooked meals ( β =0.76, 0.91), and meals containing fish, meat, eggs and beans with grain/tubers or grain/tubers and vegetables in terms of food choice (area: β =0.53, 0.53 ; BMI: β =0.55, 0.56) ( P <0.05).
Conclusions
School aged children have different preferences for different attributes of meals. The quality of school meals should be improved,the cost of buying healthy meals should be reduced,targeted family health education should be carried out,and healthy cooking methods should be advocated.

BACKGROUND:Flap transplantation technique is a commonly used surgical procedure for the treatment of severe tissue defects,but postoperative flap necrosis is easily triggered by ischemia-reperfusion injury.Therefore,it is still an important research topic to improve the survival rate of transplanted flaps. OBJECTIVE:To review the pathogenesis and latest treatment progress of flap ischemia-reperfusion injury. METHODS:CNKI,WanFang Database and PubMed database were searched for relevant literature published from 2014 to 2024.The search terms used were"flap,ischemia-reperfusion injury,inflammatory response,oxidative stress,Ca2+overload,apoptosis,mesenchymal stem cells,platelet-rich plasma,signaling pathways,shock wave,pretreatment"in Chinese and English.After elimination of irrelevant literature,poor quality and obsolete literature,77 documents were finally included for review. RESULTS AND CONCLUSION:Flap ischemia/reperfusion injury may be related to pathological factors such as inflammatory response,oxidative stress response,Ca2+overload,and apoptosis,which can cause apoptosis of vascular endothelial cells,vascular damage and microcirculation disorders in the flap,and eventually lead to flap necrosis.Studies have found that mesenchymal stem cell transplantation,platelet-rich plasma,signaling pathway modulators,shock waves,and pretreatment can alleviate flap ischemia/reperfusion injuries from different aspects and to varying degrees,and reduce the necrosis rate and necrosis area of the grafted flap.Although there are many therapeutic methods for skin flap ischemia/reperfusion injury,a unified and effective therapeutic method has not yet been developed in the clinic,and the advantages and disadvantages of various therapeutic methods have not yet been compared.Most of the studies remain in the stage of animal experiments,rarely involving clinical observations.Therefore,a lot of research is required in the future to gradually move from animal experiments to the clinic in order to better serve the clinic.
