Analyzing the spatial distribution pattern and formation factors of medicinal plant resources can provide a scientific basis for the protection and development of traditional Chinese medicine(TCM) resources. This study is based on the survey data of medicinal plant resources in 104 county-level administrative regions of Anhui province in the Fourth National Survey of TCM Resources. The global spatial autocorrelation analysis, trend surface analysis, local spatial autocorrelation analysis, hotspot analysis, and a geodetector were employed to analyze the spatial distribution pattern of medicinal plant richness, and its relationship with natural factors was explored. The results can provide a basis for the formulation of development strategies such as the protection and utilization of TCM resources, as well as offer a scientific foundation for the establishment of regional planning schemes for TCM resources in Anhui province. The results indicated that the richness of medicinal plant resources in Anhui province had significant spatial heterogeneity, exhibiting highly clustered distribution characteristics. Cold spots and hot spots presented clustered distribution patterns, with cold spots mostly located north of the Huaihe River and hot spots south of the Yangtze River. Overall, the distribution of medicinal plant resources in Anhui province showed an overall trend of high in the south and low in the north, which was consistent with the overall geomorphic trend of this province. In addition, natural factors such as altitude, precipitation, and vegetation type played an important role in the diversity and spatial distribution pattern formation of medicinal plant resources. The extraction and analysis of the spatial distribution characteristics of natural factors in cold and hot spot regions discovered that the heterogeneity of eco-environments constituted a fundamental condition for the formation of species diversity.

Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective To compare the effects of different exercise acclimatization(EA)durations on liver injury and inflammatory response in mice with exertional heatstroke(EHS).Methods A total of 168 male C57BL/6 mice were randomly assigned to four groups using a random number table:no exercise acclimation group(EA0W,n=54),1-week exercise acclimation group(EA1W,n=54),2-week exercise acclimation group(EA2W,n=54),and blank control group(n=6).The blank control group did not undergo acclimatization training or EHS modeling.The EA1W and EA2W groups underwent daily 2-hour exercise training at a speed of 10 m/min in an environment maintained at(26.0±0.5)℃for 1 and 2 weeks,respectively,followed by a 2-day rest after training completion.EHS modeling was performed in mice of EA0W,EA1W,and EA2W groups through running at 10 m/min under controlled environmental conditions(39.5℃ambient temperature,65%relative humidity).The modeling endpoint was defined as loss of consciousness accompanied by a core body temperature≥42.7℃.All modeling procedures were systematically documented.Following modeling,18 mice from EA0W,EA1W,and EA2W groups underwent 24-hour survival analysis.Blood samples from the abdominal aorta and liver tissues were collected at 6,12 and 24 hours post-modeling(6 mice per time point for each group).Plasma levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),and creatine kinase(CK)were quantified.Interleukin(IL)-1β and IL-6 concentrations were determined using enzyme-linked immunosorbent assay(ELISA).Liver tissue specimens underwent hematoxylin-eosin(HE)staining and pathological scoring.Results The EHS model was successfully established in all EA groups.When all mice in EA0W group developed EHS(65 min after the modeling initiation),the incidence rates in EA1W and EA2W groups were 50.0%and 22.2%,respectively,with a statistically significant difference between EA0W group and the latter two groups(P<0.05).When all mice in the three groups developed EHS,the time to EHS onset was significantly longer in both EA1W and EA2W groups compared to EA0W group,with EA2W group showing a longer onset time than EA1W group(P<0.05).Survival analysis revealed a significantly higher 24-hour survival rate in EA2W group(61.1%)compared to EA0W group(33.3%)(P<0.05),while no significant difference was observed between EA1W group and the other two groups(P>0.05).The levels of IL-1β,IL-6,and CK were highest at 6 h post-modeling in all EA groups(P<0.05),and liver injury was most severe at 12 h post-modeling(P<0.05).Compared to EA0W group,the levels of ALT,AST,and IL-1β,as well as liver pathology scores,were significantly lower at 12 h post-modeling in both EA1W and EA2W groups(P<0.05),with EA2W group showing significantly lower ALT and AST levels,as well as liver pathology scores than EA1W group(P<0.05).At 6 h post-modeling,CK levels were significantly higher in EA1W and EA2W groups compared to EA0W group(P<0.05),with EA2W group exhibiting higher CK levels than in EA1W group(P<0.05).Conclusions Exercise acclimation helps reduce the incidence of EHS.Following EHS onset,the survival rate of exercise-acclimated mice is higher than that non-acclimated mice,with a significantly higher survival rate in mice acclimated for 2 weeks compared to non-acclimated mice.However,no significant difference in survival rate is observed between mice acclimated for 1 week and non-acclimated mice.Additionally,exercise acclimation for 2 weeks is more effective in reducing liver injury and inflammatory responses compared to 1-week acclimation.

Objective By using intravoxel incoherent motion(IVIM)double exponential model liver multi-b value diffusion-weighted imaging(DWI)scanning technique to analyze the lesion's IVIM parameters before and after interventional treatment of hepatocellular carcinoma(HCC)with conventional transcatheter arterial chemoembolization(TACE)combined with CalliSpheres drug-loaded microspheres(DEB-TACE),based on which to quantitatively evaluate the efficacy of interventional therapy for HCC.Methods A total of 40 HCC patients,who were admitted to the Department of Interventional Therapy of Anqing Municipal Hospital of China from June 2022 to November 2023 to receive DEB-T ACE,were enrolled in this study.Routine MR examination,DWI and IVIM-DWI scan were performed before and at 1,3 and 6 months after treatment,and a total of 40 interest lesions were selected.The ADC value,perfusion fraction(f),pure diffusion coefficient(D),and perfusion-related diffusion coefficient(D*)of each lesion were analyzed.The receiver operating characteristic(ROC)curve was drawn to analyze the prognosis assessment value of IVIM-DWI parameters.Results After DEB-TACE treatment,the ADC value and D value were increased,and the f value was decreased when compared with their preoperative values,the differences were statistically significant(all P＜0.01).The ADC value and D value in the patients of effective group were remarkably higher than those in the patients of ineffective group,the differences were statistically significant(both P＜0.01);the f value in the patients of effective group was slightly lower than that in the patients of ineffective group,and the difference was statistically significant(P＜0.05).The areas under ROC curve of ADC value,D value and f value for evaluating efficacy were 0.762,0.877,and 0.708 respectively.The area under the curve for the joint assessment of the three parameters was 0.928,with the highest efficacy.Conclusion IVIM-DWI can quantitatively determine the microperfusion and activity of HCC lesions before and after interventional DEB-TACE treatment,and it can also evaluate the curative efficacy of interventional therapy for HCC as well as the outcome of HCC lesions.

Background: Diabetes-induced cardiac fibrosis is one of the main mechanisms of diabetic cardiomyopathy. As a common histone methyltransferase, enhancer of zeste homolog 2 (EZH2) has been implicated in fibrosis progression in multiple organs. However, the mechanism of EZH2 in diabetic myocardial fibrosis has not been clarified. Methods: In the current study, rat and mouse diabetic model were established, the left ventricular function of rat and mouse were evaluated by echocardiography and the fibrosis of rat ventricle was evaluated by Masson staining. Primary rat ventricular fibroblasts were cultured and stimulated with high glucose (HG) in vitro. The expression of histone H3 lysine 27 (H3K27) trimethylation, EZH2, and myocardial fibrosis proteins were assayed. Results: In STZ-induced diabetic ventricular tissues and HG-induced primary ventricular fibroblasts in vitro, H3K27 trimethylation was increased and the phosphorylation of EZH2 was reduced. Inhibition of EZH2 with GSK126 suppressed the activation, differentiation, and migration of cardiac fibroblasts as well as the overexpression of the fibrotic proteins induced by HG. Mechanical study demonstrated that HG reduced phosphorylation of EZH2 on Thr311 by inactivating AMP-activated protein kinase (AMPK), which transcriptionally inhibited peroxisome proliferator-activated receptor γ (PPAR-γ) expression to promote the fibroblasts activation and differentiation. Conclusion Our data revealed an AMPK/EZH2/PPAR-γ signal pathway is involved in HG-induced cardiac fibrosis.

Based on the focal adhesion kinase(FAK)/steroid receptor coactivator(Src)/extracellular regulated protein kinase(ERK) pathway, this study explored the effects of Xihuang Pills on angiogenesis, invasion, and metastasis in prostate cancer. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to analyze and identify the active ingredients of Xihuang Pills. Bioinformatics techniques, including R language and Perl programs, were employed to analyze the interactions between prostate cancer-related targets and the potential targets of Xihuang Pills. A subcutaneous transplantation tumor model of prostate cancer was established in nude mice using PC3 cells to verify the efficacy and molecular mechanisms of Xihuang Pills. In vitro cellular experiments, including cell proliferation assays(CCK-8), Transwell assays, scratch assays, real-time quantitative reverse transcription PCR, and Western blot, were used to detect the effects of Xihuang Pills on the proliferation, invasion, and migration of prostate cancer cells, as well as on FAK/Src/ERK pathway-related targets. LC-MS/MS identified 99 active ingredients in Xihuang Pills, including gallic acid, gentisic acid, artemisinin, corilagin, phenylbutazone-glucoside, thujic acid, and arecoic acid B. Network pharmacological analysis of the active ingredients in Xihuang Pills revealed that the FAK/Src/ERK signaling pathway was a key pathway in its anti-prostate cancer effects. In vivo and in vitro experiments confirmed that Xihuang Pills significantly inhibited the proliferation, invasion, and migration of PC3 and LNCaP cells, suppressed the growth of PC3 subcutaneous tumors, and reduced the protein expression levels related to the FAK/Src/ERK signaling pathway. In conclusion, the inhibition of angiogenesis, invasion, and metastasis by regulating the FAK/Src/ERK pathway is one of the mechanisms by which Xihuang Pills exert anti-prostate cancer effects.
