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.

Based on previous research on the promoting effect of dendrobium officinale polysaccharides (DOP) on hair growth, this study aimed to regulate the skin keratin penetration and hair follicle targeting ability of DOP through molecular weight and nano-carriers to enhance its therapeutic effect on androgenetic alopecia (AGA). Three molecular weight polysaccharides, namely high (DOP), medium (MDOP), and low (LDOP), were prepared by mannanase hydrolysis, and the corresponding liposomes (DOP-lip/MDOP-lip/LDOP-lip) were constructed. Studies have shown that DOP liposomes can effectively achieve follicular targeted delivery and promote efficient uptake by human dermal papilla cells through caveolin-mediated pathways. In the testosterone-induced AGA mouse model, LDOP-lip demonstrated excellent therapeutic effects, restoring the number and morphology of hair follicles to nearly normal levels. In summary, DOP liposomes show significant potential for promoting hair follicle repair through precise delivery and efficient cellular uptake.

Objective:To explore the role of curcumin (Cur) in improving IgA nephropathy (IgAN) and its related mechanisms.Methods:Fifty 7-month-old miR-23b knockout (miR-23b -/-) mice weighing (25±5) g were used to establish an IgAN disease model, and were randomly divided into IgAN group, IgAN+Cur (150 mg/kg) group and IgAN+Cur (300 mg/kg) group using simple randomisation. Sixteen healthy 7-month-old weighing (25±3) g C57BL/6J wild-type mice served as the normal control group. IgAN+Cur (150 mg/kg) and IgAN+Cur (300 mg/kg) groups were respectively gavaged continuously with 150 mg/kg Cur and 300 mg/kg Cur for 8 weeks, and the normal control and IgAN groups were gavaged continuously with an equal dose of 0.9% sodium chloride solution for 8 weeks. The samples of urine, serum, intestinal fluid, intestinal tissues, kidney tissues and liver tissues were collected from each group. In vitro experiments, human cloned colon adenocarcinoma (Caco-2) cells were divided into blank control (Ctrl), Ctrl+Cur (10 μmol/L), Ctrl+ Cur (60 μmol/L), tumor necrosis factor-α（TNF-α), TNF-α+Cur (10 μmol/L) and TNF-α+Cur (60 μmol/L) groups. Enzyme-linked immunosorbent assay was used to detect serum alanine transaminase, aspartate transaminase, secretory IgA (sIgA), creatinine, blood urea nitrogen, 24 h urine microalbumin, as well as sIgA, TNF-α, interleukin（IL)-6 and IL-1β in the intestinal fluids. HE staining was used to observe the effect of Cur on liver tissues, the hyperplasia of glomerular mesangial zone in kidney tissues and the morphological and structural changes of intestinal epithelial barrier, and the histopathological damage scores were performed respectively. PAS staining was used to observe the changes of glomerular basement membrane and mesangial matrix. Immunofluorescence was used to observe the deposition of immune complexes in the glomerular mesangial zone. Real-time quantitative PCR was used to detect the mRNA expression levels of B-cell activating factor ( BAFF) and a proliferation inducing ligand ( APRIL). Western blotting was used to detect the protein expression levels of tight junction proteins zonula occluden-1 (ZO-1) and occludin in the mouse intestinal tissues. The potential targets of Cur in IgAN were predicted. Western blotting was used to detect the protein expression levels of tight junction proteins, as well as Toll-like receptor 9 (TLR9), myeloid differentiation primary response protein (MyD88), nuclear factor-κB p65 (NF-κB p65) and p-NF-κB p65. Results:Genetic identification results revealed that all IgAN model mice exhibited the miR-23b -/- genotype, confirming successful model establishment. Seven-month-old mice were subsequently selected for Cur treatment. Histopathological analysis demonstrated no significant differences in hepatic tissue morphology across groups, with comparable liver histopathological injury scores and unaltered liver function parameters, thereby validating the safety of Cur administration. Compared with the normal control group, IgAN mice displayed elevated levels of serum sIgA, serum creatinine, blood urea nitrogen and 24 h urine microalbumin (all P<0.05). Renal pathological results revealed severe mesangial hypercellularity in glomeruli, higher glomerular injury scores, and notable glomerular mesangial deposits of IgA, IgG and complement C3 in IgAN mice (all P<0.05). Additionally, intestinal pathological alterations were observed, including structural changes in intestinal epithelium and Peyer's patches, accompanied by significantly higher intestinal histopathological injury scores in IgAN mice ( P<0.05). Intestinal epithelial expression levels of ZO-1 and occludin were significantly reduced, while sIgA, TNF-α, IL-1β and IL-6 in intestinal fluid were elevated (all P<0.05). Serum FITC fluorescence intensity was markedly increased, and intestinal tissue exhibited upregulated mRNA expression of BAFF and APRIL (all P<0.05). Following Cur treatment, serum sIgA level and renal function indices in mice showed partial recovery (all P<0.05). Renal pathological improvements included alleviated mesangial hypercellularity, reduced glomerular injury scores, and diminished glomerular immune complex deposition (all P<0.05). Intestinal pathologies, including epithelial and Peyer's patch lesions, were mitigated, with decreased intestinal histopathological injury scores ( P<0.05). Additionally, intestinal tight junction protein expression levels were upregulated, intestinal fluid sIgA level was reduced, inflammatory markers were attenuated, serum FITC fluorescence intensity was declined, and intestinal BAFF and APRIL mRNA expression levels were downregulated (all P<0.05). In vitro experiments demonstrated that TNF-α exposure reduced tight junction protein expression in Caco-2 cells, whereas Cur treatment reversed the effect (all P<0.05). Target prediction analysis revealed that Cur effectively bound to TLR9 structural domain in IgAN. Experimental validation confirmed that Cur treatment suppressed the upregulated protein expression levels of TLR9, MyD88, NF-κB p65 and p-NF-κB p65 in intestinal tissues of IgAN mice (all P<0.05). Conclusion:Cur has a significant effect in the treatment of IgAN and can regulate intestinal mucosal immunity by inhibiting the TLR9/MyD88/NF-κB signaling pathway, thereby reducing renal injury and protecting the kidneys.

Objective:To investigate the protective effect and its mechanism of proscillaridin A (PSD-A) on podocyte injury in lupus nephritis (LN).Methods:Molecular docking and surface plasmon resonance techniques were used to analyze the binding status of PSD-A to signal transducer and activator of transcription 1 (STAT1). The immortalized human podocyte injury model in the lupus group was induced by the serum of systemic lupus erythematosus patients, and the control and PSD-A intervention (2 nmol/L, 4 nmol/L) groups were also set up. Six female 12-week-old C57BL/6 mice were designated as the control group, and 12 female 12-week-old MRL/lpr lupus mice were randomly divided into lupus group and PSD-A intervention group by random number table method. The PSD-A intervention group was intraperitoneally injected with 5 mg/kg PSD-A, once per week for 6 consecutive weeks. While the control group and the lupus group were intraperitoneally injected with the same volume of the solvent without PSD-A. Western blotting and real-time quantitative PCR were employed to detect the relative protein and mRNA expression levels of podocin, STAT1, and interferon-induced protein with tetratricopeptide repeat 1 (IFIT1) in podocytes of each group. Enzyme-linked immunosorbent assay was used to detect the levels of serum anti-double strand DNA antibody and interferon-α in mice. Coomassie brilliant blue was used to detect the urinary protein level. HE, PAS, Masson and PASM staining and transmission electron microscopy were used to observe the pathological changes of renal tissues. Immunohistochemistry was used to examine the protein expression of podocin, STAT1 and IFIT1 in renal tissues.Results:Molecular docking and surface plasmon resonance techniques proved that PSD-A could bind to STAT1 protein and they exhibited a robust binding affinity. The podocyte experiments showed that, compared with the lupus group, the relative expression levels of podocin protein and mRNA in the PSD-A intervention group were upregulated, while the relative expression levels of STAT1 and IFIT1 protein and mRNA were downregulated (all P<0.05). The animal experiments showed that, compared with the lupus group, the serum levels of anti-double strand DNA antibody, interferon-α, and urinary protein in PSD-A intervention group were decreased, the pathological damage of renal tissues was alleviated, and the injury of renal podocytes was reduced. Immunohistochemical staining showed that the relative protein expression levels of STAT1 and IFIT1 of renal tissues in the PSD-A intervention group were lower than those in the lupus group (all P<0.05). Conclusion:PSD-A can play a protective role in podocyte injury in LN, and its mechanism may be related to the inhibition of the STAT1 signaling pathway.

Objective:To explore the differences in semen parameters and the embryo outcomes in assisted reproductive technology between infertile patients with different levels of polyzoospermia and normal sperm con-centration,focusing on the relationship between polyzoospermia and sperm nucleoprotein maturity.Methods:A total of 212 couples with polyzoospermia(concentration ≥ 125 × 106/ml)who were admitted to the Insititute of Women,Children and Reproductive Health for infertility from October 12,2020 to August 25,2022 were selected.According to the concentration range,108 couples were divided into polyzoospermia group A[concentration(125-＜250)× 106ml]and 104 couples were divided into polyzoospermia group B(concentration ≥250 × 106/ml).Another 119 infertile couples with normal sperm concentration[(20-80)× 106/ml]were selected as the control group.The difference of semen parameters among the 3 groups male patient was compared,and the cor-relation between sperm concentration and the proportion of nucleoprotein-immature sperm was analyzed.The em-bryo development and pregnancy outcomes were compared between the 3 groups of women who received in vitro fertilization using intracytoplasmic sperm injection(ICSI).Results:①The age,days of abstinence,sperm concen-tration,total number of motile spermatozoa,total number of spermatozoa,total number of progressive spermato-zoa,and proportion of nuclear protein immature spermatozoa were all higher in group A and group B male patient of polyspermia compared to the control group,while the semen volume was lower compared to the control group(P＜0.01).The results of correlation analysis showed a positive correlation between sperm concentration and the proportion of nuclear protein immature spermatozoa(r=0.240,P=0.000).②The rate of diprokaryotic fertilization(2PN)was reduced after assisted reproduction in group A and group B with polyzoospermia,among which the rate of polyzoospermia in group B was lower than that in control group(P＜0.05),and the clinical pregnancy rate was lower than that in control group(51.2％vs.69.3％),and the biochemical pregnancy rate was higher than that in control group(9.3％vs.1.3％,P＜0.05).Conclusions:The total number of progressive spermatozoa and motile spermatozoa was higher in polyzoospermia patients than control group,but the nuclear protein imma-ture of spermatozoa was significantly higher than that in control group.When the sperm concentration exceeded 125 × 106/ml,the 2PN rate decreased,and when the sperm concentration exceeded 250 × 106/ml,the clinical pregnancy rate decreased significantly.Interventions should be taken before the implementation of ART to reduce the negative effects of high sperm concentration.

Objective To observe the value of contrast-enhanced ultrasound(CEUS)for diagnosing malignant adnexal tumors.Methods Totally 112 patients with single adnexal masse were retrospectively enrolled and divided into benign adnexal tumor group(benign group,n=73)and malignant adnexal tumor group(malignant group,n=39).Clinical data,laboratory indicators,ovarian-adnexal ultrasound reporting and data system(O-RADS)classification based on conventional ultrasound(US),CEUS manifestations and CEUS classification of benign and malignant tumors were compared between groups.Multivariable logistic regression analysis of clinical and laboratory indicators being statistically different between groups,as well as US O-RADS classification and CEUS classification was performed to screen the independent predictors of malignant adnexal tumors,and combined models were constructed using forward stepwise regression method.The efficacy of each independent predictor and combined model for diagnosing malignant adnexal tumors was analyzed.Results Statistical differences of carbohydrate antigen 125(CA125),US O-RADS classification,enhancement time and level of CEUS,as well as CEUS classification were found between groups(all P＜0.05).CA125,US O-RADS classification and CEUS classification were all independent predictors of malignant adnexal tumors(all P＜0.05).Combined model Ⅰ,Ⅱ and Ⅲ were constructed based on CA125+CEUS classification,US O-RADS classification+CEUS classification and CA125+US O-RADS classification+CEUS classification,respectively.The area under the curve(AUC)of single CA125 level,US O-RADS classification,CEUS classification and combined model Ⅰ,Ⅱ and Ⅲ for diagnosing malignant adnexal tumor was 0.708,0.809,0.908,0.918,0.945 and 0.954,respectively.AUC of combined model Ⅲ was higher than that of combined model Ⅰ(Z=-2.142,P=0.032),while no significant difference of AUC was found between combined model Ⅱ and Ⅰ nor Ⅱ and Ⅲ(both P＞0.05).Conclusion CEUS could be used to effectively diagnose malignant adnexal tumor.Combining with CA125 level and US O-RADS classification could significantly improve its diagnostic efficacy.

AIM:To explore the effects of Jianpi Huatan formula on regulating T cells and helper T cells 17(Th17)cells in patients with polycystic ova-ry syndrome(PCOS)due to spleen deficiency and phlegm dampness syndrome,and conduct a model evaluation.METHODS:Ninety-two patients with spleen deficiency phlegm dampness syndrome(PCOS)admitted to our hospital from January 2023 to October 2024 were selected as the research sub-jects.Propensity score matching(PSM)method was used to match them in a 1:1 ratio,with 46 pa-tients in each group.The control group received conventional treatment,while the observation group received treatment with Jianpi Huatan for-mula on the basis of the control group.Compared and analyze the differences in clinical data and lab-oratory indicators between two groups;Compared the changes of sex hormone,glucose metabolism and TCM syndrome score before and after treat-ment in the two groups,and focused on the chang-es of regulatory T cells(Treg)and Th17 cells in the two groups before and after treatment;And used the Generalized Estimation Equation(GEE)model to analyze its improvement.Multiple linear regres-sion analysis was used to examine its correlation with the score of traditional Chinese medicine syn-drome.A time effect model of Jianpi Huatan formu-la for treating PCOS with spleen deficiency and phlegm dampness syndrome was established using a nonlinear mixed effects model.The fitting effect of the final model was evaluated through the good-ness of fit.Bootstrap was used to test and evaluate the stability of model parameters.Visual prediction testing was used to evaluate the predictive perfor-mance of the model.Typical time effect curves of traditional Chinese medicine symptom scores was simulated based on the final model for each base-line.RESULTS:After treatment,the total effective rate of the observation group was significantly high-er than that of the control group(χ2=4.842,P=0.028);Compared with before treatment,after 1months and 3 months of treatment,TC,TG,LDL-C,T,LH,FSH,AMH,FPG,FINS,HOMA-IR,the score of traditional Chinese medicine syndrome were sig-nificantly reduced,while E2 and HDL-C were signifi-cantly increased,and the improvement in the ob-servation group was significantly greater than that in the control group(P<0.05);The results of repeat-ed measures ANOVA showed significant difference-sin the time effects,inter group effects,and interac-tion effects of Treg,Th17,and Treg/Th17 between the two groups of patients(P<0.05).The GEE anal-ysis results showed that the improvement of Treg,Th17,and Treg/Th17 in the observation group were better than that in the control group(P<0.05);The results of multiple linear regression analysis showed that the levels of TC,TG,LDL-C,T,LH,FSH,AMH,FPG,FINS,HOMA-IR,Th17 were significantly positively correlated with TCM syndrome score,while the levels of E2,HDL-C,Treg,and Treg/Th17 were significantly negatively correlated with TCM syndrome score(P<0.05);The decrease in tradition-al Chinese medicine symptom score compared to baseline gradually increases over time,eventually reaching the pharmacological platform,which was consistent with the classic Emax model.After gradu-ally screening covariates,it was found that the baseline value of traditional Chinese medicine symptom score had a significant impact on the effi-cacy parameter Emax.The final model was Emax,i=15.42+1.21×(Baselinei-24.41).The goodness of fit results showed that the final model had a good fit-ting effect on the measured data.The model pa-rameters obtained from Bootstrap testing were very consistent with the original model,indicated that the model parameter estimation was robust.The visual prediction test results showed that the model had good predictive performance.The typi-cal efficacy time curve showed that the higher the baseline value of TCM symptom score,the greater the decrease in score.At 3 months of treatment,the TCM symptom score at each baseline basically decreased to below 10 points.CONCLUSION:The formula for strengthening the spleen and resolving phlegm can effectively improve the levels of Treg and Th17 in PCOS patients with spleen deficiency and phlegm dampness syndrome,and has good therapeutic effects,which is worthy of clinical appli-cation.

Mesangial cell proliferation is an early pathological indicator of diabetic nephropathy (DN). Growing evidence highlights the pivotal role of paired-related homeobox 1 (Prrx1), a key regulator of cellular proliferation and tissue differentiation, in various disease pathogenesis. Notably, Prrx1 is highly expressed in mesangial cells under DN conditions. Both in vitro and in vivo studies have demonstrated that Prrx1 overexpression promotes mesangial cell proliferation and contributes to renal fibrosis in db/m mice. Conversely, Prrx1 knockdown markedly suppresses hyperglycemia-induced mesangial cell proliferation and mitigates renal fibrosis in db/db mice. Mechanistically, Prrx1 directly interacts with the Yes-associated protein 1 (YAP) promoter, leading to the upregulation of YAP expression. This upregulation promotes mesangial cell proliferation and exacerbates renal fibrosis. These findings emphasize the crucial role of Prrx1 upregulation in high glucose-induced mesangial cell proliferation, ultimately leading to renal fibrosis in DN. Therefore, targeting Prrx1 to downregulate its expression presents a promising therapeutic strategy for treating renal fibrosis associated with DN.
