ObjectiveTo investigate the therapeutic effects and mechanism of decoctions from four kinds of processed products of Aconiti Radix Lateralis Praeparata(ARLP) in deficiency-cold syndrome. MethodsA total of 36 SD rats were randomly divided into the control group, model group, Shengfupian(SFP) group, Paofuzi(PFZ) group, Heishunpian(HSP) group and Paofupian(PFP) group with 6 rats in each group. Except for the control group, rats in other groups were administered hydrocortisone sodium succinate via intramuscular injection to induce a cold deficiency syndrome model. After 14 consecutive days, each ARLP decoction pieces was administered via continuous gastric lavage at a dose of 12 g·kg-1·d-1 for 7 d, while the control and model groups received an equivalent volume of physiological saline. After the end of administration, body weight, spleen weight and thymus weight were measured for calculating the spleen and thymus indexes. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of adrenal tissue. The fully automatic biochemistry analyzer was used to measure the total cholesterol(TC), triglyceride(TG), lactic dehydrogenase(LDH) and lactate(LAC) levels in serum. Enzyme-linked immunosorbent assay(ELISA) was employed to measure the contents of 17-hydroxycorticosteroid(17-OHCS), cortisol(CORT), triiodothyronine(T3), thyroxine(T4), thyrotropin(TSH), immunoglobulin(Ig) M, IgG, cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP). Western blot was used to measure the protein expression levels of protein kinase A(PKA), cAMP response element-binding protein(CREB), silent information regulator 1(Sirt1) and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α). And high performance liquid chromatography(HPLC) was used to determine the content of major alkaloids, followed by Pearson correlation analysis with pharmacodynamic indicators. ResultsAfter modeling, compare with the control group, the model rats exhibited symptoms such as lethargy and loose stools, mild abnormalities were observed in adrenal tissue structure, and both spleen and thymus indices were significantly reduced(P<0.01). Thyroid, adrenal and immune system functions were suppressed, with decreased serum cAMP level and significantly elevated cGMP level(P<0.01). Compared with the model group, the adrenal injury by hydrocortisone sodium succinate were repaired and the spleen index were increased significantly in all four ARLP groups(P<0.05, P<0.01). The thymus index in SFP and PFZ groups were increased significantly(P<0.05). The contents of T3, TSH, 17-OHCS and CORT were increased significantly in SFP and PFZ groups(P<0.05). In addition, the content of IgG in SFP, PFZ and PFP groups were increased significantly(P<0.01), while the content of IgM in PFZ and HSP groups were also increased significantly(P<0.05). Regarding the cyclic nucleotide system, PFZ significantly elevated cAMP level while reducing cGMP level(P<0.05), exhibiting the most pronounced effect among the four decoction pieces. For energy metabolism indicators, PFZ significantly improved abnormal markers including TC, TG, LDH, and LAC(P<0.05). HSP showed marked improvement effects on TG, LDH, and LAC(P<0.05). Both PFZ and SFP significantly elevated the expression levels of PKA, CREB, Sirt1, and PGC-1α proteins(P<0.01). Additionally, the diester alkaloids in ARLP showed a strong positive correlation with TG, IgG, and CORT, a strong negative correlation with LAC, a moderate positive correlation with T4, and moderate negative correlations with cAMP and spleen index. Monomeric alkaloids showed strong positive correlations with TG and IgG, strong negative correlations with LAC, moderate positive correlations with CORT and T4, and moderate negative correlations with cAMP and spleen index. However, the content of water-soluble alkaloids showed strong positive correlations with TC, LDH, 17-OHCS, T3, TSH, and thymus index, moderate positive correlations with cAMP, CORT, T4, and spleen index, and moderate negative correlation with cGMP. ConclusionAmong different processed ARLP decoction pieces, PFZ processed according to ZHANG Zhongjing's method exhibits the most potent warming and cold-dispelling effects. Its pharmacological actions are mediated through regulating the thyroid, adrenal, immune, cyclic nucleotide systems, and material-energy metabolism pathways. Among these, water-soluble alkaloids show strong or moderate correlations with more indicators of deficiency-cold syndrome and exhibit the highest content in PFZ. Therefore, PFZ processed according to ZHANG Zhongjing's method may exert its warming and cold-dispelling effects through water-soluble alkaloids.

OBJECTIVE:
To explore the genotype-phenotype correlation in a Chinese family with structural brain abnormalities due to variant of the TUBB gene.
METHODS:
A family undergoing prenatal diagnosis at Beijing Obstetrics and Gynecology Hospital in October 2024 was selected as the study subject. Clinical data were collected. Amniotic fluid sample was subjected to chromosomal copy number variation sequencing (CNV-seq). Trio whole-exome sequencing (Trio-WES) was carried out on the amniotic fluid and parental blood samples, and candidate variant was verified by Sanger sequencing. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2023-KY-076-01).
RESULTS:
Both prenatal ultrasound and fetal MRI showed deviation of brain midline, unilateral lateral ventriculomegaly, and bilateral gyral asymmetry. Trio-WES revealed that the fetus has harbored a maternally derived heterozygous missense variant of the TUBB gene [NM_178014.4: c.155A>G (p.N52S)]. Sanger sequencing confirmed that the woman and a previously terminated fetus both harbored the same variant. Both the proband and two fetuses exhibited similar neuroimaging abnormalities including midline deviation and asymmetrical gyri. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as likely pathogenic (PM2_Supporting+PS2_Moderate+PS3).
CONCLUSION
The heterozygous c.155A>G (p.N52S) variant was the TUBB gene probably underlay the pathogenesis of the structural brain abnormalities in this family. Above findings have expanded the phenotypic spectrum associated with the variant and facilitated the prenatal diagnosis for this family.

ObjectiveTo elucidate the mechanism by which total flavonoids of Abelmoschi Corolla (TFA) treat immunoglobulin A (IgA) nephropathy (IgAN) through serum metabolomics analysis. MethodsSPF-grade male SD rats were randomly assigned into six groups (n=10): blank, model, low-dose TFA (TFA-L, 27 mg·kg-1), medium-dose TFA (TFA-M, 54 mg·kg-1), high-dose TFA (TFA-H, 108 mg·kg-1), and losartan potassium (LST, 4.5 mg·kg-1) groups. The remaining five groups, excluding the blank group, were modeled with bovine serum albumin (BSA), lipopolysaccharide (LPS), and carbon tetrachloride (CCl4). Specifically, from weeks 1 to 10, BSA was administered via gavage every other day, and a mixture of castor oil and CCl4 was injected subcutaneously once a week, with LPS injected into the tail vein at weeks 6 and 8. After successful modeling, each intervention group was administrated with the medication prepared with distilled water once daily by gavage for a continuous period of 4 weeks. The levels of 24-hour urinary total protein (24 h UP) and serum creatinine (SCr) were quantified by kits, and the serum IgA level was determined by enzyme-linked immunosorbent assay (ELISA). Renal pathological changes were observed by hematoxylin-eosin (HE) staining and periodic acid-Schiff (PAS) staining. Renal IgA deposition was assessed by immunofluorescence (IF). Endoplasmic reticulum (ER) stress was observed by transmission electron microscopy. Western blot and immunohistochemistry (IHC) were employed to detect the expression of ER stress-related factors. Non-targeted metabolomics was used to screen differential metabolites for analysis, and key metabolites arachidonic acid (AA), prostaglandin E2 (PGE2), and cyclooxygenase-2 (COX-2) were validated. ResultsCompared with the blank group, the model group showed increased 24-hour urine protein (24 h UP) and serum creatinine (SCr) levels (P<0.01), obvious renal pathological damage, elevated serum IgA level (P<0.01), increased renal AA and PGE2 levels (P<0.01), and up-regulated protein levels of COX-2, glucose-regulated protein 78 (GRP78), phosphorylated eukaryotic initiation factor 2α (P-EIF2α), activating transcription factor 4 (ATF4), inositol-requiring enzyme 1α (IRE1α), and spliced X-box binding protein 1 (XBP1s) in the renal tissue (P<0.05, P<0.01). Compared with the model group, the intervention groups showed reductions in 24 h UP and SCr levels (P<0.05, P<0.01), alleviated renal pathological injury, decreased serum IgA level (P<0.05, P<0.01), and reduced renal AA and PGE2 levels (P<0.01). Western blot and IHC results showed that TFA reduced the levels of COX-2, GRP78, P-EIF2α, ATF4, IRE1α, and XBP1s in the renal tissue (P<0.05, P<0.01). Metabolomics results indicated that 51 commonly differential metabolites were found among the normal, model, and TFA-M groups. TFA ameliorated IgAN by affecting metabolic pathways related to the biosynthesis of arachidonic acid and arginine through L-aspartic acid, prostaglandin 2α, leukotriene B4, leukotriene D4, among others. ConclusionTFA can regulate the arachidonic acid metabolism pathway, thereby modulating ER stress, reducing renal damage, and ameliorating IgA nephropathy.

Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

ObjectiveTo investigate the effects of Qizhujianwei granules (QZJW) on abnormal proliferation and malignant transformation of gastric mucosal cells in rats with gastric intraepithelial neoplasia (GIN) and to explore the related mechanisms. MethodsA total of 80 SPF male Wistar rats were used. A GIN rat model was established using a four-factor comprehensive method consisting of methylnitronitrosoguanidine (MNNG), ranitidine, irregular feeding patterns, and sodium salicylate. Except for the normal group, after successful modeling, the rats were randomly divided according to body weight into a model group, a Moluodan group (0.55 g·kg-1), and a QZJW group (7.34 g·kg-1), with 12 rats in each group. All groups were treated for 8 weeks. The general characteristics of the rats and morphological changes of the gastric mucosa were observed. Histopathological changes of the gastric mucosa were examined by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of pepsinogenⅠ (PGⅠ), pepsinogenⅡ (PGⅡ), and gastrin (G-17), as well as the expression level of transforming growth factor-β1 (TGF-β1) in gastric mucosal tissue, and the PGⅠ/PGⅡ ratio was calculated. Immunohistochemistry (IHC) was used to detect the localization and expression levels of proliferating cell nuclear antigen (Ki-67) and Vimentin in gastric mucosal tissue. Western blot analysis was used to determine the protein expression levels of Wnt family member 3A (Wnt3a), β-catenin, CyclinD1, proto-oncogene Cmyc, transforming growth factor-β receptor Ⅰ (TGFβRⅠ), intracellular signaling transducers Smad2/3, phosphorylated (p)-Smad2/3, twist family transcription factor (Twist1), and Vimentin in gastric mucosal tissue. ResultsCompared with the normal group, the model group showed characteristic changes including dim eyes, pale ears and claws, dark-red tongue, and reduced luster of the tail. The gastric mucosa appeared pale, with surface congestion and erosion. The gastric mucosal glands were disordered, the nuclear-to-cytoplasmic ratio increased, and local tumor cells were observed. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly decreased (P<0.01), while the level of G-17 was significantly increased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly increased (P<0.05, P<0.01), whereas the ratio of p-Smad2/3 to Smad2/3 was significantly decreased (P<0.05). Compared with the model group, the general characteristics and gastric mucosal conditions of rats in the Moluodan group and the QZJW group were improved. HE staining showed that QZJW could effectively block the malignant progression of GIN. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly increased (P<0.05, P<0.01), while the level of G-17 was significantly decreased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly decreased (P<0.05, P<0.01). ConclusionQZJW have a therapeutic effect on rats with GIN. The mechanism may involve inhibition of the Wnt/β-catenin signaling pathway to regulate the cell cycle and suppress abnormal cell proliferation. Meanwhile, it may inhibit epithelial-mesenchymal transition by suppressing the TGF-β1/Smad/Twist1 signaling pathway, thereby blocking the malignant progression of GIN.

Objective To investigate the distribution characteristics of Oncomelania hupensis snails in Yunnan Province fol-lowing interruption of schistosomiasis transmission, so as to provide the evidence for assessing the risk of schistosomiasis transmission and scientifically formulating the schistosomiasis surveillance program. Methods According to the requirements of the National Schistosomiasis Surveillance Scheme (2020 Edition), O. hupensis snail surveillance data were collected from 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province from 2020 to 2024, including area of snail survey, area of snail habitats, area of re-emerging snail habitats, number of frames surveyed, number of frames with O. hupensis snails, number of O. hupensis snails captured, and number of living snails, and the occurrence of frames with snails and mean density of living snails were calculated. Changes in snail status over the 5-year period from 2020 to 2024 and the differences in snail distributions specified by epidemic intensity, environmental type, and vegetation type were analyzed. Results The areas of snail survey increased from 1 727.96 hm2 in 2020 to 3 894.45 hm2 in 2024 (peak) across 18 schistosomiasis-endemic counties (cities, districts) in Yunnan Province during the period from 2020 through 2024. The areas of snail habitats increased from 70.36 hm2 in 2020 to a peak in 2023 (172.04 hm2), followed by a reduction to 132.36 hm2 in 2024, and the areas of re-emerging snail habitats increased from 42.71 hm2 in 2020 to a peak in 2022 (78.43 hm2), followed by a reduction to 40.21 hm2 in 2024. The occurrence of frames with snails and mean density of living snails increased from 1.24% (3 025/244 404) and (0.033 2 ± 0.038 7) snails/0.1 m2 in 2020 to peaks at 2.03% (6 231/307 563) and (0.066 9 ± 0.068 4) snails/0.1 m2 in 2023, followed by reductions to 1.04% (5 829/559 941) and (0.032 6 ± 0.057 7) snails/0.1 m2 in 2024, respectively. There was a significant difference in the occurrence of frames with snails over the 5-year study period (χ2 = 1 962.95, P < 0.05), and the occurrence of frames with snails reduced by 48.71% in 2024 relative to in 2023 (χ2 = 1 411.05, P < 0.005); however, there was no significant difference in the mean density of living snails over the 5 years (H = 5.310, P > 0.05). There were significant differences in the occurrence of frames with snails (χ2 = 481.27, P < 0.05) and mean density of living snails (H = 6.872, P < 0.05) in schistosomiasis-endemic areas with different epidemic intensities. The occurrence of frames with snails (χ2 = 25.32 and 38.70, both P values < 0.017) and mean density of living snails (Z = 28.55 and 49.96, both P values < 0.017) were higher in schistosomiasis transmission-interrupted and eliminated areas with snails than in schistosomiasis-eliminated areas without snails, and the occurrence of frames with snails (χ2 = 453.54, P < 0.017) and mean density of living snails (Z = −56.97, P < 0.017) were higher in schistosomiasis-eliminated areas with snails than in schistosomiasis transmission-interrupted areas with snails. O. hupensis snails were mainly distributed in paddy fields, dry farmlands and ditches; however, the occurrence of frames with snails (13.40%, 424/3 164) and mean density of living snails [(0.252 8 ± 0.158 7) snails/0.1 m2] were higher in ponds/weirs than in other types of environments (both P values < 0.05). Rice, dry farmland crops and weeds were main vegetations in which O. hupensis snails were distributed, and the occurrence of frames with snails (2.29%, 7 111/310 140) and mean density of living snails [(0.072 3 ± 0.018 9) snails/0.1 m2] were higher in weeds than in other types of environments (both P values < 0.05). Conclusions O. hupensis snails have been effectively controlled in Yunnan Province following implementation of integrated schistosomiasis control measures; however, there are still risk factors for schistosomiasis transmission, including reduced attention to schistosomiasis control and snail re-emergence. Improved control efforts and surveillance system construction and timely identification of risk factors of snail status and timely management are recommended to ensure the achievement of the target of schistosomiasis elimination as scheduled.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.
9.Impact of milk and egg supplementation on body composition and bone mineral density of rural primary school students in Yunnan Province
Chinese Journal of School Health 2025;46(10):1401-1405
Objective:
To investigate the impact of milk and egg supplementation on body composition and bone mineral density of rural primary school students in Yunnan Province, so as to provide a reference for developing targeted nutritional intervention strategies.
Methods:
In December 2023, a cluster sampling method was adopted to select students from grades one to three in four primary schools each from Jinggu and Shidian countys of Yunnan Province, as the intervention group (662 students). Additionally, two boarding primary schools were selected from each county based on the principle of matching scale and student numbers as the control group (455 students). Starting from April 2023, the intervention group received 200 mL milk and 50 g eggs during the break on school days for 8 months, while the control group maintained their usual diet behavior. Body composition was measured by using bioelectrical impedance analysis, and distal radial bone mineral density was assessed via dual energy X-ray absorptiometry in April and December 2023. The intervention effects were analyzed by using a difference in-differences approach.
Results:
The final measurements of body fat percentage, skeletal muscle mass and fat free mass of the intervention group and the control group of primary school students were significantly higher than the baseline values, and the net effect of milk and egg intervention on these body composition indicators was not statistically significant ( P >0.05, both before and after adjustment). In contrast, bone mineral density increased significantly by 0.02 g/cm 2 in the intervention group. The net intervention effect on bone mineral density was statistically significant ( β=0.02, 95%CI =0.00-0.04), and remained significant after model adjustment ( β=0.02, 95%CI =0.00-0.04) (both P < 0.05). Subgroup analysis showed statistically significant effects of the intervention among girls ( β=0.02, 95%CI =0.00-0.04), day students ( β=0.04, 95%CI =0.01-0.07), and students with normal nutritional status ( β=0.02, 95%CI =0.00-0.04) (all P <0.05). No significant effect of milk and egg supplementation was observed on body composition indicators (all P <0.05).
Conclusions
Milk and egg supplementation can improve bone mineral density among rural primary school students in Yunnan Province. It is recommended that rural school aged children should increase intake of milk and eggs to support growth and development.
