ObjectiveTo evaluate the clinical efficacy and safety of Jingmaiyan granules (composed of Lonicerae Japonicae Flos, Sedi Herba, Paeoniae Radix Rubra, Moutan Cortex, Rhei Radix et Rhizoma Praeparata, and Glycyrrhizae Radix et Rhizoma) combined with external application of Jinhuang Ointment in treating acute-stage blood heat stasis type superficial thrombophlebitis (ST) of lower extremities, and to explore their effects on hemorheology and serum inflammatory factors. MethodsA randomized, double-blind, placebo-controlled clinical trial was conducted. A total of 124 patients with lower extremity ST were randomized into two groups(62 cases in each group). The control group received external application of Jinhuang ointment and oral placebo treatment, while the observation group received external application of Jinhuang ointment and oral Jingmaiyan granules. Both groups were treated for 2 weeks. The clinical symptom scores, therapeutic efficacy of traditional Chinese medicine (TCM) syndrome, pain visual analog scale (VAS) scores, hemorheological indices [including whole blood high-shear, medium-shear, and low-shear viscosity, as well as plasma viscosity (PV)], and inflammatory factors [C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] were compared before and after treatment. ResultsAfter 2 weeks of treatment, the total effective rate in the observation group (98.3%, 60/62) was significantly higher than that in the control group (83.8%, 52/62), with a statistically significant difference (Z=3.512 1, P<0.05). Compared with pre-treatment scores, the scores for skin color, skin temperature, swelling, pain, and cord or nodules were significantly reduced in both groups (P<0.05), with more pronounced improvement in the observation group (P<0.05). Additionally, compared with pre-treatment levels, the whole blood viscosity (low-, medium-, and high-shear) significantly improved in both groups after treatment (P<0.05), with more marked improvement in the observation group (P<0.05). Furthermore, the plasma viscosity, CRP, IL-6, and TNF-α levels were significantly reduced in both groups after treatment (P<0.05), with more pronounced improvement observed in the observation group (P<0.05). ConclusionThe combination of external application of Jinhuang ointment and oral Jingmaiyan granules effectively improves clinical symptoms, hemorheological abnormalities, and inflammatory responses in patients with acute stage blood heat stasis type ST of lower extremities. The treatment is safe and holds clinical promotion value.

OBJECTIVE To investigate the effects of baicalin (BC) on insulin resistance in rats with gestational diabetes mellitus (GDM) and its underlying mechanism based on the adenosine monophosphate-activated protein kinase (AMPK)/suppressor of variegation 3-9 homolog 1 (SUV39H1)/histone H3 lysine 9 trimethylation (H3K9me3) axis. METHODS A GDM rat model was established by a combination of a high-fat diet and streptozotocin injection. The successfully modeled rats were divided into the GDM group, BC low-dose group, BC high-dose group, and high-dose of BC+AMPK inhibitor (Compound C) group, with 10 rats in each group. Another 10 pregnant rats fed a normal diet served as the control group. Rats in each group were given corresponding drugs/normal saline intragastrically and/or intraperitoneally, once daily for 2 consecutive weeks. After the last administration, the levels of fasting blood glucose (FBG), pancreatic function indexes [fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), insulin sensitivity index (ISI)], blood lipid indexes (total cholesterol, triglyceride, low-density lipoprotein cholesterol), liver function indexes (alanine transferase, aspartate transferase, alkaline phosphatase), inflammatory indicators (C-reactive protein, interleukin-1β, interleukin-6), metabolic regulatory protein [complement-C1q/tumor necrosis factor-related protein 3 (CTRP3)], insulin sensitivity related factors [glucose transporter 4 (GLUT4), adiponectin], and oxidative stress indicators [superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA)] were measured. Pathological changes in liver tissue were observed, and the expressions of proteins related to the AMPK/SUV39H1/H3K9me3 axis in liver tissue were detected. RESULTS Compared with the GDM group, rats in the BC low- and high-dose groups showed varying degrees of improvement in pathological changes such as disordered cell arrangement, vacuolar degeneration, lipid deposition, and inflammatory cell infiltration in liver tissue. Their FBG and FINS levels, HOMA-IR, the levels of blood lipid indexes, liver function indexes, inflammatory indicators and MDA, and the expressions of SUV39H1 and H3K9me3 were significantly decreased or down-regulated, while metabolic regulatory protein, insulin sensitivity-related factors and AMPK protein phosphorylation levels were significantly increased ( P <0.05). The improvement was more significant in the BC high-dose group ( P <0.05). Compound C could significantly reverse the ameliorative effects of high-dose BC on the above quantitative indicators ( P <0.05). CONCLUSIONS BC can significantly reduce oxidative stress and inflammatory responses, increase serum levels of CTRP3, GLUT4 and adiponectin, thereby improving insulin resistance in GDM rats. These effects may be related to the activation of AMPK and inhibition of SUV39H1-mediated H3K9me3 modification.

Abnormal activation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway is involved in the pathogenesis of diffuse large B-cell lymphoma (DLBCL). In recent years, inhibitors targeting JAK2 and STAT3 have emerged as promising therapeutic candidates in DLBCL. This review summarizes the efficacy and safety profiles of JAK2 inhibitors (e.g., ruxolitinib) and STAT3 inhibitors (direct small-molecule inhibitors, the antisense oligonucleotide, and proteolysis targeting chimeras, etc.) in preclinical models and clinical trials. Accumulating evidence indicates that JAK2 and STAT3 inhibitors exhibit antitumor activity and are generally well tolerated in a subset of DLBCL patients. Meanwhile, the development of novel drug delivery systems has significantly enhanced the stability, bioavailability, and targeting ability of the compounds. Furthermore, JAK2 and STAT3 inhibitors may exhibit synergistic effects when combined with other therapy strategies (such as combinations with B-cell receptor signaling pathway inhibitors, immunomodulators, or other targeted drugs). However, current clinical applications are still in their early stages. Future research should concentrate on precision treatment strategies based on the genetic subtyping of DLBCL, and further refine the delivery systems for inhibitors as well as combination drug regimens to improve clinical outcomes.

Objective:
To investigate the prevalence of depressive symptoms and their associated factors among students in Zhejiang Province, so as to provide evidence for targeted prevention strategies.
Methods:
A stratified cluster random sampling method was used to select 23 829 college students and primary and secondary school students aged 11-22 years in Zhejiang Province from December 2019 to February 2020. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Three machine learning algorithms, including Logistic regression, random forest, and eXtreme Gradient Boosting (XGBoost), were applied to construct predictive models, and key associated factors were identified by comparing model performance.
Results:
The detection rate of depressive symptoms among students in Zhejiang Province was 19.92%; the rates were 17.20% in boys and 22.87% in girls( χ 2=164.89, P <0.05). The CES-D total score was 9.00(4.00,13.00). Multiple Logistic regression analysis revealed that loneliness had the strongest association with depressive symptoms ( AOR =9.58, 95% CI =8.90-10.30), while bullying exposure ( AOR =4.39, 95% CI =4.02-4.80), female students( AOR =1.81, 95% CI =1.68-1.94),never eating breakfast ( AOR = 2.34,95% CI =2.00-2.67) and overweight/obesity( AOR =1.10,95% CI =1.08-1.12) were significant associated factors of depressive symptoms among students (all P <0.05). Analysis based on the XGBoost model produced highly consistent results, identifying the above 5 factors as the core features with the highest correlation strength (all P <0.05).
Conclusions
Female, loneliness, bullying exposure, frequency of weekly breakfast and BMI are strongly associated with depressive symptoms among students. Mental health education for high risk groups should be strengthened, and coordinated prevention efforts between families and schools are recommended.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

To develop a guideline terminology system and promote its standardization, thereby enhancing medical staff's accurate understanding and correct application of guidelines. A systematic search was conducted for guideline development manuals and method ological literature (as of October 25, 2024). After screening, relevant terms from the guideline planning and launching stages were extracted and standardized. The term list and definitions were finalized through discussion and evaluation at a consensus conference. A total of 36 guideline manuals and 14 method ological articles were included, and 27 core terms were identified. The standardization of guideline terminology is essential for improving guideline quality, facilitating interdisciplinary communication, and enhancing other related aspects. It is recommended that efforts to advance the standardization and continuous updating of the terminology system should be prioritized in the future to support the high-quality development of guidelines.

OBJECTIVE To explore the effects of CD20 coding gene (MS4A1) polymorphism on the blood concentration and efficacy of rituximab in patients with non-Hodgkin’s lymphoma. METHODS A prospective observational study was conducted on 160 newly diagnosed non-Hodgkin’s lymphoma patients who received the R-CHOP regimen at the Sun Yat Sen University Cancer Center from January 2016 to December 2020, with a minimum follow-up period of approximately 5 years. The blood concentration of rituximab was detected by enzyme-linked immunosorbent assay. MS4A1 tagSNPs were selected by Haploview4.2 software, including rs1051461, rs17155034, rs4939364, and rs10501385. The genotype of MS4A1 was detected by Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Univariate linear regression analysis was employed to examine the correlation between various factors(demographic, clinical, and genotypic variables) in patients and the steady-state trough concentration of rituximab during the first course of treatment, followed by multivariate linear regression analysis. Kaplan-Meier curves were drawn to evaluate progression-free survival (PFS) and overall survival (OS). Using MS4A1 genotype and tumor stage as independent variables, Cox regression model was employed to evaluate the factors influencing patient prognosis. RESULTS The blood concentration of rituximab in MS4A1 rs10501385 CC carriers was 15.20 μg/mL,which was significantly lower than 21.95 μg/mL in AA+AC carriers (P<0.05). The multivariate linear regression model incorporating tumor stage and MS4A1 rs10501385 polymorphism explained 7.3% of the interindividual variability in rituximab concentrations. Compared with MS4A1 rs1051461 CC carriers, CT+TT carriers had significantly prolonged PFS and OS (P<0.05). The Cox proportional hazards regression model showed that the MS4A1 rs1051461 CC genotype (HR=4.406, 95%CI:1.743-11.137, P<0.05) and tumor Ⅲ&Ⅳ (HR=3.233, 95%CI: 1.413-7.399, P<0.05) were independent risk factors for PFS. CONCLUSIONS The tumor staging and MS4A1 rs10501385 polymorphism are key influencing factors for blood concentration of rituximab, and MS4A1 rs1051461 polymorphism significantly affects PFS in non-Hodgkin’s lymphoma patients.

Guided by the concept of quality by design(QbD), this study optimizes the calcination and quenching process of calcined Magnetitum and establishes the XRD characteristic spectra of calcined Magnetitum, providing a scientific basis for the formulation of quality standards. Based on the processing methods and quality requirements of Magnetitum in the Chinese Pharmacopoeia, the critical process parameters(CPPs) identified were calcination temperature, calcination time, particle size, laying thickness, and the number of vinegar quenching cycles. The critical quality attributes(CQAs) included Fe mass fraction, Fe~(2+) dissolution, and surface color. The weight coefficients were determined by combining Analytic Hierarchy Process(AHP) and the criteria importance though intercrieria correlation(CRITIC) method, and the calcination process was optimized using orthogonal experimentation. Surface color was selected as a CQA, and based on the principle of color value, the surface color of calcined Magnetitum was objectively quantified. The vinegar quenching process was then optimized to determine the best processing conditions. X-ray diffraction(XRD) was used to establish the characteristic spectra of calcined Magnetitum, and methods such as similarity evaluation, cluster analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to evaluate the quality of the spectra. The optimized calcined Magnetitum preparation process was found to be calcination at 750 ℃ for 1 h, with a laying thickness of 4 cm, a particle size of 0.4-0.8 cm, and one vinegar quenching cycle(Magnetitum-vinegar ratio 10∶3), which was stable and feasible. The XRD characteristic spectra analysis method, featuring 9 common peaks as fingerprint information, was established. The average correlation coefficient ranged from 0.839 5-0.988 1, and the average angle cosine ranged from 0.914 4 to 0.995 6, indicating good similarity. Cluster analysis results showed that Magnetitum and calcined Magnetitum could be grouped together, with similar compositions. OPLS-DA discriminant analysis identified three key characteristic peaks, with Fe_2O_3 being the distinguishing component between the two. The final optimized processing method is stable and feasible, and the XRD characteristic spectra of calcined Magnetitum was initially established, providing a reference for subsequent quality control and the formulation of quality standards for calcined Magnetitum.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

This paper aimed to explore the effects of Duzhong Decoction(DZD)-containing serum on the proliferation and osteoblast differentiation of MC3T3-E1 cells through L-type voltage-gated calcium channels(L-VGCCs). L-VGCCs inhibitors, nifedipine and verapamil, were used to block L-VGCCs in osteoblasts. MC3T3-E1 cells were divided into a control group, a low-dose DZD-containing serum(L-DZD) group, a medium-dose DZD-containing serum(M-DZD) group, a high-dose DZD-containing serum(H-DZD) group, a nifedipine group, a H-DZD + nifedipine group, verapamil group, and a H-DZD + verapamil group. The CCK-8 method was used for cell proliferation analysis, alkaline phosphatase(ALP) assay kits for intracellular ALP activity measurement, Western blot for protein expression level in cells, real-time fluorescence quantitative PCR technology for intracellular mRNA expression level determination, fluorescence spectrophotometer for free Ca~(2+) concentration determination in osteoblasts, and alizarin red staining(ARS) for mineralized nodule formation in osteoblasts. The experimental results show that compared to the control group, DZD groups can promote MC3T3-E1 cell proliferation, ALP activity, and mineralized nodule formation, increase intracellular Ca~(2+) concentrations, and upregulate the protein expression of bone morphogenetic protein 2(BMP2), collagen Ⅰ(COL1), α2 subunit protein of L-VGCCs(L-VGCCα2), and the mRNA expression of Runt-related transcription factor 2(RUNX2), and BMP2. After blocking L-VGCCs with nifedipine and verapamil, the intervention effects of DZD-containing serum were inhibited to varying degrees. Both nifedipine and verapamil could inhibit ALP activity, reduce mineralized nodule areas, and downregulate the expression of bone formation-related proteins. Moreover, the effects of DZD-containing serum on increasing MC3T3-E1 cell proliferation, osteoblast differentiation, and Ca~(2+) concentrations, upregulating the mRNA expression of osteoprotegerin(OPG) and protein expression of phosphorylated protein kinase B(p-Akt) and phosphorylated forkhead box protein O1(p-FOXO1), and upregulating phosphatase and tensin homolog(PTEN) expression were reversed by nifedipine. The results indicate that DZD-containing serum can increase the Ca~(2+) concentration in MC3T3-E1 cells to promote bone formation, which may be mediated by L-VGCCs and the PTEN/Akt/FoxO1 signaling pathway, providing a new perspective on the mechanism of DZD in treating osteoporosis.
