ObjectiveTo investigate the effects of Jianpi Qinghua granules on blood glucose fluctuations in patients with newly diagnosed overweight/obese type 2 diabetes mellitus (T2DM) and Qi-Yin deficiency syndrome from the perspective of skeletal muscle mass and function, while providing new insights for the treatment of diabetes. MethodsThis study employed a randomized, double-blind, placebo-controlled design. A total of 110 newly diagnosed overweight/obese T2DM patients meeting the inclusion criteria were randomly assigned to either the traditional Chinese medicine (TCM) group (54 cases) or the control group (56 cases). Patients in the TCM group received Jianpi Qinghua Granules, while those in the control group received a placebo. Both groups underwent dietary and exercise guidance. After 12 weeks of intervention, blood glucose fluctuations were assessed using the following parameters: time in the target blood glucose range (TIR), mean daily blood glucose (MBG), standard deviation of mean daily blood glucose (SDBG), mean amplitude of glycemic excursions (MAGE), coefficient of variation of blood glucose (CV), glycated hemoglobin (HbA1c) achievement rate, fasting plasma glucose (FPG), and 2 hour postprandial glucose (2 hPG). Skeletal muscle mass was measured by dual-energy X-ray absorptiometry (DXA), while skeletal muscle function was evaluated using a handheld dynamometer for distal muscle strength and a 5-time sit-to-stand test for lower limb function. Additionally, pancreatic islet function and TCM syndrome scores were analyzed. ResultsNo significant differences were observed in baseline data between the two groups before intervention, ensuring comparability. After treatment, compared to the control group, the TCM group showed a significant increase in TIR (P<0.01). While the SDBG and CV decreased, and MBG and MAGE increased in the TCM group, these differences were not statistically significant. Notably, the TCM group exhibited significant reductions in 2 hPG (P<0.01) and HbA1c (P<0.05), though the decrease in FPG was not statistically significant. The HbA1c achievement rate in the TCM group was significantly higher than that in the control group (χ2=45.498, P<0.01). In terms of skeletal muscle mass and function, the TCM group demonstrated a significant increase in handgrip strength (P<0.01) and a significant reduction in the 5-time sit-to-stand duration (P<0.05). However, although body fat percentage increased, leading to a decrease in skeletal muscle mass and the ratio of skeletal muscle to fat, these changes were not statistically significant. For pancreatic islet function, the TCM group showed significant reductions in fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR) (P<0.01). Additionally, the TCM syndrome score in the TCM group was significantly reduced (P<0.01). ConclusionJianpi Qinghua granules may reduce blood glucose fluctuations in newly diagnosed overweight/obese T2DM patients with Qi-Yin deficiency syndrome by enhancing skeletal muscle function, improving pancreatic islet function, and ameliorating related TCM syndromes.

Parkinson's disease (PD) is a common neurodegenerative disorder characterized by motor impairments, with its pathological mechanisms involving multiple processes such as the degeneration of dopaminergic neurons and the abnormal aggregation of α-synuclein. Current Western medical treatments face challenges including diminished long-term efficacy and motor complications. In recent years, Traditional Chinese Medicine (TCM) has demonstrated advantages in the prevention and treatment of PD through its systematic regulatory capabilities, featuring multi-component, multi-target, and multi-pathway approaches.This article systematically reviews the roles of seven key signaling pathways-NF-κB, AMPK/mTOR, PI3K/Akt, MAPKs, Nrf2/ARE, Wnt/β-catenin, and BDNF/TrkB-in the pathological process of PD and the regulatory mechanisms of TCM. Research indicates that active ingredients of Chinese herbs and compound formulations can synergistically modulate these pathways, exerting comprehensive effects in inhibiting neuroinflammation, alleviating oxidative stress, promoting autophagy to clear abnormal proteins, and enhancing neurotrophic support. These signaling pathways form a complex regulatory network through crosstalk among key nodal molecules, constituting an intricate regulatory system in PD pathology. The multi-target intervention characteristics of TCM align well with this network-based regulatory requirement, achieving integrated anti-inflammatory, antioxidant, autophagy-regulating, and neurorestorative effects through synergistic multi-pathway modulation. This article systematically outlines the mechanisms of TCM in the coordinated regulation of multiple pathways, providing a theoretical basis for elucidating the pathological process of PD and the intervention mechanisms of TCM, while also offering new perspectives and directions for modern research on TCM in the prevention and treatment of PD.

Diabetic kidney disease (DKD), a common complication of diabetes mellitus, is a leading global cause of end-stage renal disease (ESRD). Current therapeutic strategies primarily focus on symptomatic management but exhibit limited efficacy in halting disease progression to ESRD, and some drugs carry non-negligible toxic side effects. Traditional Chinese medicine (TCM) has a long history in treating DKD, with single TCM and TCM compounds demonstrating unique advantages in multi-target, multi-pathway, and multi-effect therapeutic interventions. Tripterygium wilfordii (TW), known for its effects in promoting blood circulation, dredging collaterals, dispelling wind, removing dampness, reducing swelling, and alleviating pain, contains bioactive components such as Tripterygium glycosides (TWG), triptolide (TPL), tripdiolide (TPD), and celastrol (CEL). The active ingredients possess various functions, including regulating immune-inflammatory balance, ameliorating renal fibrosis and glomerulosclerosis, combating oxidative stress, protecting podocytes, and improving glucose and lipid metabolism, all of which play a significant role in the treatment of DKD. This review summarized the mechanisms underlying the therapeutic effects of T. wilfordii and its active ingredients on DKD, aiming to provide insights for clinical management and novel drug development of DKD.

Objective To investigate the predictive value of the triglyceride glucose (TyG) index in major adverse cardiovascular events (MACE) in patients after coronary artery bypass grafting (CABG) surgery. Methods A retrospective collection of patients with coronary heart disease who underwent CABG treatment in the Department of Cardiac Surgery Ward 1, the 7th People’s Hospital of Zhengzhou, from 2015 to 2024 was conducted. The X-tile software was used to calculate the optimal cutoff value of the TyG index, and patients were divided into two groups based on this optimal cutoff value. The association between the TyG index and MACE was explored through univariate analysis, Kaplan-Meier survival curve analysis, and Cox regression analysis. The predictive ability of the TyG index was evaluated by important factor ranking and the area under the receiver operating characteristic curve (AUC). Results A total of 998 patients were included, with 630 patients having a TyG index ≤8.80, including 438 males and 192 females, with a median age of 60 (55, 65) years; and 368 patients with a TyG index >8.80, including 236 males and 132 females, with a median age of 63 (57, 69) years. Cumulative survival curves showed that the incidence of MACE in the TyG index≤8.80 group was significantly lower than that in the TyG index>8.80 group (log-rank test, P<0.001). Cox regression analysis indicated that TyG>8.80 was an independent risk factor for MACE [HR=2.581, 95%CI (1.201, 5.549), P<0.001]. In the important factor ranking, the TyG index had the greatest impact on MACE. The TyG index could enhance the predictive ability of the MACE prediction model, with the AUC increasing from 0.712 to 0.872. Conclusion The TyG index is independently associated with MACE after CABG, and may improve the discriminative performance of the predictive model in internal samples; however, prospective, multicenter studies and external validation are still required for confirmation.

Objective To explore the diagnostic value of exhaled volatile organic compounds (VOCs) for cystic fibrosis (CF). Methods A systematic search was conducted in PubMed, EMbase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases up to August 7, 2024. Studies that met the inclusion criteria were selected for data extraction and quality assessment. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS), and the risk of bias and applicability of included prediction model studies were assessed by the prediction model risk of bias assessment tool (PROBAST). Results A total of 10 studies were included, among which 5 studies only identified specific exhaled VOCs in CF patients, and another 5 developed 7 CF risk prediction models based on the identification of VOCs in CF. The included studies reported a total of 75 exhaled VOCs, most of which belonged to the categories of acylcarnitines, aldehydes, acids, and esters. Most models (n=6, 85.7%) only included exhaled VOCs as predictive factors, and only one model included factors other than VOCs, including forced expiratory flow at 75% of forced vital capacity (FEF75) and modified Medical Research Council scale for the assessment of dyspnea (mMRC). The accuracy of the models ranged from 77% to 100%, and the area under the receiver operating characteristic curve ranged from 0.771 to 0.988. None of the included studies provided information on the calibration of the models. The results of the Prediction Model Risk of Bias Assessment Tool (PROBAST) showed that the overall bias risk of all predictive model studies was high, and the overall applicability was unclear. Conclusion The exhaled VOCs reported in the included studies showed significant heterogeneity, and more research is needed to explore specific compounds for CF. In addition, risk prediction models based on exhaled VOCs have certain value in the diagnosis of CF, but the overall bias risk is relatively high and needs further optimization from aspects such as model construction and validation.

ObjectiveTo explore the effects of the Tibetan medicine Sanwei Doukoutang (SWDK) on cognitive dysfunction in mice suffering from Alzheimer's disease (AD) and its related mechanism. MethodsFifty SPF 5 × FAD mice were randomly divided into model group, total ginsenoside group(0.04 g·kg-1), high-, medium-, and low-dose groups of SWDK (32.60, 16.30, 8.15 g·kg-1), with 10 mice in each group, and ten wild-type mice of the same age were used as the normal group, male and female in 1∶1. Gavage administration was performed once daily for 8 weeks. The Morris water maze test and contextual fear memory experiment were used to observe learning and memory function. Hematoxylin-eosin (HE) staining was utilized to observe the changes in the pathomorphology of brain tissue in mice. The levels of synaptophysin (SYP) and postsynaptic dense substance 95 (PSD95) in mice serum were detected by enzyme-linked immunosorbent assay (ELISA). The positive expression of brain-derived neurotrophic factor(BDNF) in the dentate gyrus (DG) region of mouse brain tissue was observed by immunohistochemistry (IHC). The protein levels of BDNF, Wnt family member 3A(Wnt3a), and β-catenin were detected in the hippocampus of mice by Western blot. ResultsCompared with the normal group of mice, the model group of mice had significantly more complex swimming routes and lower swimming speed (P<0.01), significantly lower percentage of time spent in the target quadrant (P<0.01), and a significantly lower percentage of freezing time (P<0.05). The number of neurons in the hippocampal region of mice was obviously reduced and unevenly arranged. The levels of SYP and PSD95(P<0.01) in the serum of mice were reduced, and the positive expression of BDNF in the DG region of the brain tissue of mice was reduced. The levels of hippocampal BDNF, Wnt3a, and β-catenin proteins in the hippocampus of mice were obviously reduced (P<0.05, P<0.01). Compared with the model group, the mice in the SWDK group and the total ginsenoside group had significantly shorter swimming routes, the high- and medium- dose SWDK groups significantly higher swimming speeds (P<0.01), significantly higher percentage of time spent in the target quadrant (P<0.01), obviously higher percentage of Freezing time (P<0.05), and obviously more neurons in the hippocampal region of the mice with tighter arrangement. The mice had elevated levels of serum SYP (P<0.05, P<0.01), PSD95 (P<0.01), increased BDNF-positive cells in the DG region of brain tissue, and obviously elevated levels of BDNF, Wnt3a, and β-catenin proteins in the hippocampus of mice (P<0.05, P<0.01). ConclusionSWDK can significantly improve the cognitive dysfunction of AD mice, and its mechanism may be related to regulating the Wnt/β-catenin signaling pathway, which promotes BDNF expression and thereby enhances synaptic plasticity, allowing neuronal signaling to be restored.

Objective:To evaluate the clinical equivalence between a domestic calcipotriol/betamethasone dipropionate ointment and the originator product in the treatment of stable plaque psoriasis.Methods:A multicenter, randomized, double-blind, three-arm, parallel-group, active- and placebo-controlled study was conducted, and 449 patients aged 18 - 65 years with stable plaque psoriasis were enrolled from 25 hospitals (such as the First Affiliated Hospital of China Medical University). Eligible patients had a baseline physician's global assessment (PGA) score of ≥ 3 points, baseline body surface area (BSA) involvement of 5% - 30%, and a target lesion psoriasis area and severity index (TL-PASI) for plaque elevation of ≥ 3 points. Participants were randomly assigned in a 2:2:1 ratio to the test group ( n = 179), reference group ( n = 180), and placebo group ( n = 90), and applied the domestic calcipotriol/betamethasone dipropionate ointment, originator product, and ointment base respectively, once daily in the evening for 4 weeks. Efficacy and safety were assessed at weeks 1, 2, and 4. The primary efficacy endpoints were the treatment success rates and clinical success rates in each group at week 4. The per-protocol set (PPS) was used for the primary efficacy analysis, and the intention-to-treat (ITT) set for supplementary efficacy analysis. Equivalence between the test and reference preparations was tested using the Cochran-Mantel-Haenszel method adjusted for randomization strata. Superiority of the test and reference preparations over the placebo was also tested. Measurement data were compared among the 3 groups using analysis of variance or non-parametric tests, while treatment success rates, clinical success rates, and incidence rates of adverse reactions were compared using the chi-square test. Results:The ITT, PPS, and safety sets included 447, 420, and 448 patients, respectively. In the ITT set, patients were aged 43.6 ± 12.8 years, including 320 (71.6%) males and 127 (28.4%) females, and the disease duration was 11.21 ± 9.05 years; 316 (70.7%) had a PGA score of 3 points and 131 (29.3%) had a PGA score of 4 - 5 points. No significant differences in the baseline characteristics (including age, sex, disease duration and disease severity) were observed among the 3 groups (all P > 0.05). Based on the PPS analysis, the treatment success rates were 57.9% (99/171) in the test group, 50.3% (86/171) in the reference group, and 7.7% (6/78) in the placebo group, and the clinical success rates were 57.9% (99/171), 50.3% (86/171), and 10.3% (8/78), respectively; both the test and reference groups were superior to the placebo group in both treatment and clinical success rates (all P < 0.001) ; the rate differences for treatment success (90% confidence interval [ CI]: -1.3% - 16.4%) and clinical success (90% CI: -1.3% - 16.3%) between the test and reference groups were entirely within the pre-defined equivalence margin (-20% - 20%). Subgroup analyses by baseline PGA scores: for patients with a baseline PGA score of 3 points, the treatment success rates in the test, reference, and placebo groups were 60.8% (73/120), 52.1% (62/119), and 11.1% (6/54), respectively, and the corresponding clinical success rates were 61.7% (74/120), 53.8% (64/119), and 13% (7/54), respectively; the test and reference groups did not differ significantly in treatment or clinical success rates (both P > 0.05), but both showed higher success rates than the placebo group (all P < 0.001) ; the results of statistical comparisons among the 3 groups in patients with a baseline PGA score of 4 - 5 points were consistent with those observed in patients with a baseline PGA score of 3 points. The percentage reductions in PGA and TL-PASI scores from baseline to weeks 1, 2, and 4 showed significant differences among the 3 groups, which were significantly higher in the test and reference groups than in the placebo group (all P < 0.001), but did not differ between the test and reference groups (all P > 0.05). The primary adverse reactions were local skin reactions, such as pruritus, pain, and erythema. The incidence rates of adverse reactions were 8.9% (16/179) in the test group, 7.3% (13/179) in the reference group, and 7.8% (7/90) in the placebo group, with no significant difference among the 3 groups ( P > 0.05) . Conclusions:The domestic calcipotriol/betamethasone dipropionate ointment demonstrated clinical equivalence to the originator product in the treatment of stable plaque psoriasis, and the two agents exhibited comparable efficacy for patients with varying degrees of disease severity, and were comparable in the speed and degree of clinical improvement, with similar favorable safety profiles.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the anemia conditions and characteristics of iron metabolism during different stages of pregnancy in women with different genotypes of thalassemia.Methods:This cohort study selected 3 303 singleton pregnant women who underwent regular prenatal examinations and genetic tests of thalassemia and were delivered at Maternal & Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2019 to December 2023. According to the results of thalassemia gene testing, the women were divided into groups: those without thalassemia genes served as the control group (1 539 cases), and those with thalassemia genes (1 764 cases) were further divided based on genotype into the -α/αα group (326 cases), --/αα or -α/-α group (649 cases), point mutation α-thalassemia group (201 cases), β 0-thalassemia group (368 cases), β +-thalassemia group (91 cases), and α combined with β-thalassemia group (129 cases). Hemoglobin (Hb) and serum ferritin (SF) levels were measured in the first, second, and third trimester of pregnancy. Differences in anemia and iron reserves among the groups at different pregnancy stages were compared using repeated measures analysis of variance, LSD test, Kruskal-Wallis rank-sum test, and Bonferroni correction. Results:Compared to the first trimester, Hb levels decreased in the second and third trimester across all groups (LSD test, all P<0.05), and the severity of anemia increased (Bonferroni correction, all P<0.017). The severity of anemia varied among the groups at the same pregnancy stage ( Hfirst trimester=918.20, Hsecond trimester=1 224.50, Hthird trimester=980.19; all P<0.001), and Hb levels also differed ( Ffirst trimester=282.54, Fsecond trimester=352.31, Fthird trimester=239.02; all P<0.001). The β 0-thalassemia group had higher rates of moderate anemia in the first, second, and third trimester of pregnancy [38.6% (142/368), 85.3% (314/368), and 73.6% (271/368)] compared to other groups (Bonferroni correction, all P<0.002), and lower Hb levels [(102.1±8.9), (92.0±7.3), and (94.6±7.7) g/L] than other groups (LSD test, all P<0.05). As pregnancy progresses, SF levels in each group of pregnant women gradually decreased (LSD test, all P<0.05), and the degree of iron deficiency worsened (Bonferroni correction, all P<0.05). The iron deficiency rate in thalassemia pregnant women during the third trimester ranges from 21.5% (79/368) to 46.0% (150/326). The degree of iron deficiency varies among groups within the same gestational period ( Hfirst trimester=79.13, Hsecond trimester=203.98, Hthird trimester=130.55; all P<0.001), and SF levels also differ ( Ffirst trimester=17.28, Fsecond trimester=44.60, Fthird trimester=31.87; all P<0.001). Among them, the β 0-thalassemia group had the lowest iron deficiency rates in the second, and third trimesters [9.8% (36/368), and 21.5% (79/368)] (Bonferroni correction, all P<0.002). SF levels in the β 0-thalassemia and β +-thalassemia groups were higher than those in other groups during each gestational period (LSD test, all P<0.05). Conclusions:Pregnant women with thalassemia may experience varying degrees of iron deficiency during pregnancy, with the severity of iron deficiency and anemia increasing with gestational age. The degree of iron deficiency and anemia during pregnancy varies among pregnant women with different genotypes of thalassemia. Clinically, individualized management should be provided for pregnant women with thalassemia based on their genotypes, with dynamic monitoring of anemia and iron metabolism changes.
