ObjectiveTo investigate the effect of Yaoshu Zhuyu Fang on the regulation of the microRNA-17-5P (miR-17-5P)/murine double minute 2 (MDM2)/p53 axis in the proliferation and apoptosis of rat intervertebral disc annulus fibrosus cells, and its potential molecular mechanism. MethodsIntervertebral disc annulus fibrosus tissues were obtained from 8-week-old SPF-grade male SD rats, and annulus fibrosus cells were isolated and obtained by enzyme digestion and mechanical dispersion. Annulus fibrosus cells were divided into 6 groups: Group C was the blank control group, in which annulus fibrosus cells were not treated with interleukin-1β (IL-1β) but were cultured in RPMI 1640 complete medium. Group β was the degeneration model group constructed by treating annulus fibrosus cells with 10 ng/mL IL-1β for 24 h. Group β+B was the IL-1β + blank serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then treated with RPMI 1640 medium containing 5% blank serum for 24 h. Group β+W was the IL-1β + Yaoshu Zhuyu Fang-containing serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then treated with RPMI 1640 medium containing 5% Yaoshu Zhuyu Fang-containing serum for 24 h. Group β+I was the IL-1β + miR-17-5P inhibitor group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then transfected with miR-17-5P inhibitor. Group β+I+W was the IL-1β + miR-17-5P inhibitor + Yaoshu Zhuyu Fang-containing serum group, in which annulus fibrosus cells were first treated with IL-1β to construct the degeneration model, then transfected with miR-17-5P inhibitor, and finally treated with RPMI 1640 medium containing 5% Yaoshu Zhuyu Fang-containing serum for 24 h. CCK-8 assay was used to detect cell survival rate. Flow cytometry was used to detect cell apoptosis. Real-time quantitative PCR was used to detect the expression levels of miR-17-5P, MDM2 mRNA, and p53 mRNA in cells. Western blotting was used to detect the protein expression levels of MDM2 and p53 in cells. Dual-luciferase reporter system was used to analyze the targeting relationship between miR-17-5P and MDM2. ResultsCompared with Group C, Group β showed a significant decrease in cell survival rate (P<0.001), a significant increase in cell apoptosis rate (P<0.001), significantly increased expression of miR-17-5P, p53 mRNA, and p53 protein (P<0.001), and significantly decreased expression of MDM2 mRNA and protein (P<0.001). Compared with Group β, Group β+W, Group β+I, and Group β+I+W showed significantly increased cell survival rate, significantly decreased apoptosis rate, significantly decreased expression of miR-17-5P, p53 mRNA, and p53 protein, and significantly increased expression of MDM2 mRNA and protein (P<0.001). Moreover, changes in the above indicators were greater in Group β+I+W (P<0.001). Circular RNA Interactome predicted that miR-17-5P had specific binding sites with the 3' untranslated region (3'UTR) of MDM2. Transfection of miR-17-5P mimic significantly reduced the luciferase expression level of co-transfected luciferase reporter plasmid containing wild-type MDM2 3'UTR (P<0.05), but had no significant effect on luciferase expression in cells co-transfected with luciferase reporter plasmid containing mutant MDM2 3'UTR (P>0.05). ConclusionYaoshu Zhuyu Fang down-regulates the expression of miR-17-5P, promotes the synthesis of MDM2 protein, thereby down-regulates p53, promotes proliferation, and inhibits the apoptosis of rat intervertebral disc annulus fibrosus cells.

OBJECTIVE To study the clinical characteristics and potential risk factors for infection in patients with multiple myeloma （MM） following treatment with bortezomib. METHODS Clinical data were retrospectively collected from MM patients who received bortezomib-based treatment regimens at the Department of Hematology， the Second Affiliated Hospital of Soochow University， from October 2021 to February 2025. The collected data primarily included demographic characteristics， disease characteristics of MM， treatment regimens， occurrence of infections and corresponding management measures， and prophylactic medication use. Univariate and multivariate Logistic regression analyses were conducted to identify potential risk factors for MM complicated with infection. RESULTS Among the 284 MM patients treated with bortezomib， 132 patients （46.5%） experienced at least one infection. The predominant types of infections were respiratory tract infections and gastrointestinal infections. Univariate analysis showed that age at initial diagnosis， pathological classification， and grade of myelosuppression were influencing factors for infection in MM patients （ P ＜0.05）. Further analysis of influencing factors for the two main types of infections revealed that sex， age at initial diagnosis， pathological classification， treatment regimen， and smoking history were influencing factor s for respiratory tract infections in MM patients （ P ＜0.05）； BMI， pathological classification， treatment regimen， and grade of myelosuppression were influencing factors for gastrointestinal infections in MM patients （ P ＜0.05）. Multivariate Logistic regression analysis indicated that age≥70 years and the presence of grade Ⅳ myelosuppression before treatment were risk factors for infection in MM patients， while the IgG-λ type was a protective factor against infection （ P ＜0.05）. CONCLUSIONS The incidence of infection is relatively high in MM patients receiving bortezomib-based treatment regimens， with respiratory and gastrointestinal infections being the most common. Age at initial diagnosis， grade of myelosuppression， and pathological classification are influencing factors for infection in MM patients.

Background: The tight junction protein claudin18.2 (CLDN18.2) has been implicated in poor prognosis and suboptimal immunotherapy response in gastric cancer (GC). This study investigates the clinicopathological relevance of CLDN18.2 expression and its association with molecular subtypes in GC patients from a high-incidence region, combining transcriptomic and proteomic approaches to explore how CLDN18.2 contributes to progression and metastasis. Methods: A retrospective cohort of 494 GC patients (2019–2024) underwent immunohistochemical analysis for CLDN18.2, Epstein-Barr virus (Epstein–Barr virus–encoded RNA), p53, human epidermal growth factor receptor 2 (HER2), and mismatch repair proteins (MLH1, MSH2, PMS2, and MSH6). CLDN18.2 positivity was defined as moderate to strong (2+/3+) membranous staining in ≥75% of tumor cells. Clinicopathological correlations, biomarker associations, and survival outcomes were evaluated. Transcriptomic and proteomic sequencing was performed to explore molecular mechanisms. Results: CLDN18.2 positivity was observed in 26.9% (133/494) of gastric adenocarcinomas. CLDN18.2-positive tumors correlated with TNM stage (p = .003) and shorter overall survival (p = .018). No associations were identified with age, sex, HER2 status, microsatellite instability, or Epstein-Barr virus infection. Transcriptomic profiling revealed CLDN18.2-high tumors enriched in pathways involving cell junction disruption, signaling regulation, and immune modulation. Proteomic profiling showed that tumors with high CLDN18.2 were enriched in multiple mechanism-related pathways such as integrated metabolic reprogramming, cytoskeletal recombination, immune microenvironment dysregulation, and pro-survival signaling. These mechanisms may collectively contribute to tumor progression and metastasis. Conclusions CLDN18.2 overexpression is associated with poor prognosis in GC patients. Transcriptomic and proteomic analyses demonstrate that CLDN18.2 promotes tumor progression and metastasis, underscoring its potential as an independent prognostic factor in regions with a high incidence of GC.

This study systematically examined the effects of atomization as a transdermal permeation enhancer on the transdermal delivery of active ingredients with different physicochemical properties and investigated the underlying mechanisms. Porcine ear skin served as an in vitro model, and skin permeation experiments were conducted using Franz diffusion cells. Receptor fluids were collected at specific time points, and samples of the stratum corneum and viable epidermis–dermis were separated and prepared. Quantitative and visualization methods, including high-performance liquid chromatography, fluorescence derivatization, and confocal laser scanning microscopy, were used to compare skin retention and transdermal permeation of adenosine (AD), tranexamic acid (TXA), calcein (CAL), and tocopheryl acetate (TA) under atomized and non-atomized conditions. Additionally, transepidermal water loss (TEWL) measurements and attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR) were employed to analyze the mechanism behind the penetration enhancement caused by atomization. The findings showed that atomization increased skin retention within the stratum corneum and viable epidermis–dermis, as well as the transdermal permeation of all four active ingredients to varying degrees. The most significant enhancement was observed for TXA, which has a relatively low molecular weight and moderate lipophilicity, while the enhancement effects for highly hydrophilic AD and highly lipophilic TA were comparatively limited; however, atomization significantly increased the skin retention of TA. TEWL results indicated that skin permeability increased within 4 hours after atomization and largely recovered within 8 hours. ATR-FTIR analysis suggested that atomization may facilitate transdermal delivery by disrupting the lipid order and keratin conformation in the stratum corneum.This study provides theoretical support and experimental references for the advancement of atomization transdermal delivery technology, as well as the design and development of related atomization products.

Puerariae Lobatae Radix and Puerariae Thomsonii Radix are the dried roots of Pueraria lobata and Pueraria thomsonii of the Leguminosae family， respectively. Since their separate inclusion in the 2005 edition of Pharmacopoeia of the People's Republic of China， the two herbs have been individually recorded. Although they share the same functions and indications， the required content of puerarin differs by a factor of up to eightfold between them. The current quality standard relies solely on a single indicator， puerarin， which fails to reflect the correlation between chemical constituents and core therapeutic effects. This has resulted in prominent issues of mixed use in clinical practice and production， thereby constraining the high-quality development of the industry. Modern research has demonstrated that Puerariae Lobatae Radix contains a comprehensive range and higher content of isoflavonoid constituents， while Puerariae Thomsonii Radix is rich in starch and polysaccharides. Puerariae Lobatae Radix exhibits stronger effects in antipyresis， cardiovascular and cerebrovascular protection， and central analgesia， while Puerariae Thomsonii Radix demonstrates greater advantages in anti-inflammation， hypoglycemia， and peripheral analgesia. Based on this， the chemical material bases of Puerariae Lobatae Radix and Puerariae Thomsonii Radix at both the macromolecule and micromolecule levels were systematically reviewed and compared. The pharmacodynamic material bases and mechanisms of action underlying their three core therapeutic effects， namely "relieving exterior syndrome and clearing heat"， "promoting fluid production to quench thirst"， and "dredging channels and activating collaterals"， were summarized. The most highly correlated common metabolic pathway shared by both herbs for these three therapeutic effects is the arachidonic acid metabolic pathway， and their common core target is prostaglandin-endoperoxide synthase 2 （PTGS2）. This review provided clinical application recommendations based on the therapeutic differences between the two herbs， elucidated the scientific connotation of their "same origin but different effects"， and， grounded in the quality marker （Q-Marker）， proposed the concept of efficacy-related Q-Marker based on "substance-efficacy-syndrome" association， as well as a novel strategy for efficacy-oriented quality evaluation. Preliminary screening of quality markers associated with different therapeutic effects was also conducted. This study aims to provide critical scientific evidence for the precise clinical application of Puerariae Lobatae Radix and Puerariae Thomsonii Radix， the improvement of quality standards， and the high-quality development of the industry.

ObjectiveTo observe the clinical efficacy and safety of Zhinao capsules in the treatment of mild and moderate sleep disorders in Alzheimer's disease patients with the syndrome of spleen-kidney deficiency and combined phlegm and stasis. MethodsA randomized， double-blind， placebo， controlled clinical trial design was adopted， and 60 Alzheimer's disease patients aged 50-85 years with mild and moderate sleep disorders due to spleen-kidney deficiency and combined phlegm and stasis were included. According to the randomized numble table method， the patients were assigned into a treatment group and a control group （30 in each group， with 29 patients in the treatment group and 28 patients in the control group finally completing the trial）. The treatment group was treated with donepezil hydrochloride tablets combined with Zhinao capsules， and the control group was treated with donepezil hydrochloride tablets combined with the simulant of Zhinao capsules for 12 weeks. The Pittsburgh sleep quality index （PSQI）， smart bracelet sleep monitoring， epworth sleeping scale （ESS）， Mini-Mental State Examination （MMSE）， Activities of Daily Living （ADL）， and traditional Chinese medicine symptoms were scored. Furthermore， the brain-derived neurotrophic factor （BDNF） and gamma-aminobutyric acid （GABA） levels were measured. ResultsAfter 12 weeks of treatment， the total response rate of clinical efficacy assessment in the treatment group reached 89.7%， which was significantly higher than that （21.4%） in the control group （Z=-5.14， P<0.01）. After treatment， the TCM symptom scores declined in both groups （P<0.01）， and the scores in the treatment group were lower than those in the control group （P<0.01）. After treatment， the treatment group showed decreased total score and seven component scores of the PSQI scale （P<0.05， P<0.01）， and the scores in the treatment group were lower than those in the control group （P<0.05， P<0.01）. After treatment， the treatment group showed increases in the duration of deep sleep， light sleep， rapid eye movement sleep， and total sleep at night and decreases in the time to fall asleep， the number of awakenings from sleep at night， and the time for sporadic daytime naps （P<0.01）. The control group did not show significant changes in the duration of light sleep， time to fall asleep， and number of awakenings from sleep at night. Moreover， the treatment group outperformed the control group in terms of the indicators above （P<0.05， P<0.01）. After treatment， the treatment group showed decreased scores of ESS， ADL and its subscales physical self-maintenance scale （PSMS）， and Instrumental Activities of daily living scale （IADLs） and increased score of MMSE and levels of BDNF and GABA （P<0.05， P<0.01）. There was no significant difference in PSMS between the two groups， and the treatment group was significantly better than the control group in terms of the rest of the above indicators （P<0.05， P<0.01）. Patients in neither groups complained of uncomfortable symptoms. ConclusionZhinao capsules have significant clinical efficacy in treating patients with mild and moderate sleep disorders in Alzheimer's disease patients with the syndrome of spleen-kidney deficiency and combined phlegm and stasis. Zhinao capsules can significantly reduce PSQI， ESS， and ADL scores， increase the MMSE score and the expression of BDNF and GABA， effectively optimize the structure of sleep， improve the intelligence， and enhance the ability of daily life， without causing uncomfortable symptoms. The mechanism may be related to the increase in the expression of sleep/wake-related neurotransmitters.

[Objective] To evaluate the therapeutic effect of autologous platelet-rich plasma (PRP) for chronic endometritis (CE). [Methods] A retrospective analysis was conducted on 36 patients with CE who had failed antibiotic treatment. The clinical outcomes, pregnancy rates, and early miscarriage rates were assessed following PRP treatment. Meanwhile, the CE patients of receiving first/second-line Clinical drug treatment were used as the control experiment group. [Results] Among the 36 patients treated with PRP, the effective rate was 83.33%. The clinical pregnancy rate in the treatment group was higher than that in the control group [17-36(65.38%) vs 14/27(51.85%), P>0.05], and the early miscarriage rate was lower 2/17(11.76%) vs 2/14(14.29%), P>0.05]. [Conclusion] PRP therapy is effective for CE, with no antibiotic resistance or side effects, and can be widely promoted as a treatment option.

Avian coccidiosis, an acute parasitic disease that mainly harms chicks, is widely prevalent across the world, which poses a serious threat to poultry industry. Because of the single prophylactic formulations, veterinary clinical treatment of coccidiosis mainly relies on chemically synthesized agents, polyether ionophores and Chinese herbal medicines. The introduction of novel anticoccidial drugs is slow for a long period of time, and there is an increasing problem of anticoccidial drug resistance following long-term use, which has become an urgent problem to be solved in poultry industry. This review summarizes the levels of anticoccidial drug resistance across China from 2018 to 2023, and analyzes the resistance to various anticoccidial agents in coccidia. It is indicated that the overall prevalence of anticoccidial drug resistance is high in coccidia, and development of novel anticoccidial agents and products with reduced antibiotics use and alternatives of antibiotics is of an urgent need.

ObjectiveNonalcoholic fatty liver disease （NAFLD） is a metabolic stress liver injury. Ferroptosis is involved in the occurrence and development of NAFLD. Exploring the efficacy and mechanism of schisandrin B in treating NAFLD facilitates the development of strategies for the prevention and treatment of NAFLD. MethodsThe molecular structure of schisandrin B was obtained by searching against PubChem， and the related targets were predicted by SwissTargetPrediction. The active ingredients and their targets were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the high-throughput experiment- and reference-guide database of traditional Chinese medicine （HERB）. GeneCards and FerrDb were searched for the targets of NAFLD and ferroptosis. The common targets were taken as the core targets， and the protein-protein interaction network of the core targets was established. DAVID was used for gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses. Finally， molecular docking was performed between schisandrin B and core targets， and the binding energy was calculated. C57BL/6 mice were fed with a methionine and choline-deficiency （MCD） diet for the modeling of NAFLD. Mice were randomized into normal， model， positive drug （essentiale）， and low- and high-dose schisandrin B groups. The body mass and liver index of mice were measured after drug administration. The levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in the serum and those of total cholesterol （TC）， triglyceride （TG）， malondialdehyde （MDA）， glutathione （GSH）， and Fe²⁺ in the liver homogenate were measured by biochemical assay kits. The pathological changes of the liver tissue were observed by hematoxylin-eosin （HE） and red oil O staining. Enzyme-linked immunosorbent assay was employed to determine the levels of interleukin （IL）-6， IL-1β， tumor necrosis factor （TNF）-α， and 4-hydroxynonenal （4-HNE） in the serum. Western blotting and real-time PCR were employed to determine the protein and mRNA levels， respectively， of solute carrier family 7 member 11 （SLC7A11）， solute carrier family 3 member 2 （SLC3A2）， glutathione peroxidase 4 （GPX4）， transferrin， and ferritin heavy chain （FTH） in the liver tissue. ResultsA total of 2 370， 2 547， and 1 451 targets of schisandrin B， NAFLD， and ferroptosis were obtained， in which 90 common targets were shared by the three. Enrichment analyses predicted 505 GO terms and 92 KEGG pathways. Molecular docking suggested that schizandrin B had strong binding affinity with the key targets of ferropstosis （SLC7A11 and SLC3A2）. Animal experiments showed that schizandrin B significantly decreased the liver index， lowered the levels of ALT， AST， TC， TG， IL-6， IL-1β， and TNF-α， alleviated hepatocyte ballooning and inflammatory cell infiltration， and reduced lipid accumulation in the liver of NAFLD mice. In addition， schisandrin B significantly lowered the levels of MDA， 4-HNE， and Fe²⁺， elevated the level of GSH， up-regulated the protein and mRNA levels of SLC7A11， SLC3A2， and GPX4， and down-regulated the protein and mRNA levels of transferrin in the liver tissue. ConclusionSchisandrin B can alleviate NAFLD by inhibiting ferroptosis in hepatocytes.
