BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

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.

Objective:To investigate the effects of repeated high acceleration(+Gz)on implant osseointegration in SD rats.Methods:18 SD rats were divided into+Gz and control groups randomly(n=9),and 1 implant was placed in each femur of the rat's lower limb.24 hours postoperatively,the experimental rats were exposed to+Gz of 4 to 9 G with 1 G/s environment 3 times a week,while the con-trol rats were fed normally.3 rats from each of the 2 groups were sacrificed at 2,4 and 8 weeks after implantation.Micro-CT,sequential fluorescence double labeling,and histological examination were perfomed for the analysis of implant osseointegration.Results:The bone volume fraction(BV/TV),trabecular number(Tb.N),mineral apposition rate(MAR),implant-bone contact rate(BIC)and bone area in implant thread(BA)of the+Gz group were significantly lower than those of the control group at 2 weeks(P＜0.05),and so as to MAR,BA at 4 weeks(P＜0.05),while there was no significant difference of the parameters at 8 weeks after implantation.Conclusion:In SD rats early exposure to+Gz environment postoperatively may have a negative effect on initial osseointegration by slowing bone forma-tion.However,it will not lead to poorer bone mass when sustained over a long period.

Objective:To explore the impact of transcatheter edge-to-edge repair (TEER) devices on mitral valve regurgitant flow convergence post-procedure using computational fluid dynamics(CFD), and to seek solutions for accurately measuring effective regurgitant orifice area(EROA) after TEER.Methods:Multimodal fusion was conducted based on preoperative cardiac CT images and intraoperative three-dimensional transesophageal echocardiography(3DTEE) of 33 patients with mitral valve regurgitation undergoing TEER at Renmin Hospital of Wuhan University from January 2020 to August 2023. Using this data, CFD models of mitral valve regurgitation post-TEER, including with and without the TEER device, were constructed. The distance (D) from the midpoint of the mitral regurgitation orifice to the TEER device was measured. The proximal isovelocity surfice area(PISA) radius with and without the TEER device was measured, and the corresponding EROA1 and EROA2 based on this was calculated. The EROA correction factor CC=EROA2/EROA1 was calculated.Results:A total of 42 sets of CFD models with mild or greater residual mitral regurgitation, both with and without the TEER device, and 50 sets of PISA were obtained. Based on the relative position of PISA to the TEER device, four types of PISA were observed: Type 1: PISA away from the TEER device (D>R, 14 cases), with a CC of 0.93±0.07; Type 2: PISA adjacent to the TEER device (D

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-positive bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-positive bacteria from blood cultures in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:A total of 3 163 strains of Gram-positive pathogens were collected from 51 member units，and the top five bacteria were Staphylococcus aureus（ n=1 147，36.3%），coagulase-negative Staphylococci（ n=928，29.3%）， Enterococcus faecalis（ n=369，11.7%）， Enterococcus faecium（ n=296，9.4%）and alpha-hemolyticus Streptococci（ n=192，6.1%）. The detection rates of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）were 26.4%（303/1 147）and 66.7%（619/928），respectively. No glycopeptide and daptomycin-resistant Staphylococci were detected. The sensitivity rates of Staphylococcus aureus to cefpirome，rifampin，compound sulfamethoxazole，linezolid，minocycline and tigecycline were all >95.0%. Enterococcus faecium was more prevalent than Enterococcus faecalis. The resistance rates of Enterococcus faecium to vancomycin and teicoplanin were both 0.5%（2/369），and no vancomycin-resistant Enterococcus faecium was detected. The detection rate of MRSA in southern China was significantly lower than that in other regions（ χ2=14.578， P=0.002），while the detection rate of MRCNS in northern China was significantly higher than that in other regions（ χ2=15.195， P=0.002）. The detection rates of MRSA and MRCNS in provincial hospitals were higher than those in municipal hospitals（ χ2=13.519 and 12.136， P<0.001）. The detection rates of MRSA and MRCNS in economically more advanced regions（per capita GDP≥92 059 Yuan in 2022）were higher than those in economically less advanced regions（per capita GDP<92 059 Yuan）（ χ2=9.969 and 7.606， P=0.002和0.006）. Conclusions:Among the Gram-positive pathogens causing bloodstream infections in China， Staphylococci is the most common while the MRSA incidence decreases continuously with time；the detection rate of Enterococcus faecium exceeds that of Enterococcus faecalis. The overall prevalence of vancomycin-resistant Enterococci is still at a low level. The composition ratio of Gram-positive pathogens and resistant profiles varies slightly across regions of China，with the prevalence of MRSA and MRCNS being more pronounced in provincial hospitals and areas with a per capita GDP≥92 059 yuan.

Objective:To retrospectively analyze the causes of missed diagnosis of clinically significant PCa(csPCa)by targe-ted biopsy(TB).Methods:This retrospective study included 652 males aged(71.32±16.53)years with elevated PSA and ab-normal MRI signals detected in our hospital from June 2018 to December 2020.We further examined the patients by transperineal pros-tatic TB and systematic biopsy(SB),analyzed the detection rates of PCa and csPCa by TB and SB,and investigated the causes of missed diagnosis of csPCa in TB using the fishbone diagram.Results:The total detection rate of PCa and csPCa by TB combined with SB was 45.7%(298/652),and that of csPCa was 37.4%(244/652),with 38 cases of csPCa missed in TB,including 23 cases of negative TB and 15 cases of low ISUP grade.The causes of missed diagnosis of csPCa by TB included low MRI image quality,PSA density≤0.15 ng/ml/cm3,target area<10 mm,and PI-RADS 2 score≤3.The detection rate of csPCa by TB alone was 31.6%,which was increased by 5.8%(P=0.027)when TB combined with SB.Conclusion:TB combined with SB yields a higher de-tection rate of csPCa than either used alone.Missed diagnosis of csPCa by TB is closely related to the characteristics of tumor and MR image of the target area.

Coronary perforation is when a contrast agent or blood flows outside a blood vessel through a tear in a coronary artery.In this case,we reported a case of percutaneous coronary intervention for coronary calcified lesions,which led to iatrogenic coronary perforation and cardiac tamponade after the use of Shockwave balloon to treat intracoronary calcified nodules,and the management of PCI-related CAP was systematically reviewed through the literature.

Objective To compare the performance of machine learning(ML)and individualized treatment effect(ITE)models based on deep learning in providing personalized treatment recommendations using real-world clinical datasets,and construct personalized drug treatment recommendation models for pegylated liposomal doxorubicin(PLD)and epirubicin(EPI)in postoperative breast cancer patients,and assist clinical decision-making by evaluating the treatment effects of these drugs.Methods Clinical data of 904 breast cancer patients admitted at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine was collected retrospectively,including 387 cases treated with PLD and 517 cases treated with EPI.The two groups were compared using propensity score matching to assess the 5-year disease free survival(DFS)outcome.Six ITE models,including CFR_WASS,were used to predict the 5-year DFS probability of patients under two drug treatments.Six machine learning(ML)models,including Random Forest,were used as baselines for performance analysis and comparison.Model's Predictive performance was evaluated based on the AUROC.The effectiveness of treatment recommendations was assessed by calculating the difference of 5-year rates between the group where the actual treatment used was consistent with the treatment recommended by the model and the control group.Results Among the 153 matched cases,there was no statistically significant difference in 5-year DFS outcomes between the two groups.In 16 pairs of cases,the PLD group showed better clinical outcomes than the EPI group,and in 12 pairs of cases,the EPI group had better clinical outcomes than the PLD group,confirming individual differences in treatment benefit between the two drugs.The CFR_WASS model achieved the optimal predictive performance(AUROC value was 0.736 8),and there was no significant difference in 5-year DFS rates between most ML groups and the control group;The 5-year DFS rate in the ITE group was lower than that in the control group(P<0.01),showing significant differences.Among them,the 5-year DFS rate in the CFR_WASS group was 2.13%lower than that in the control group.Conclusion The ITE model is more accurate in estimating the individualized treatment effects of two drugs compared to the ordinary ML model,providing effective individualized treatment recommendations,and has certain clinical application value.
