Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective To explore the clinical efficacy,safety and changes in sexual function of 450 nm blue laser vaporization resection of the prostate in the treatment of benign prostatic hyperplasia(BPH).Methods The clinical data of 132 BPH patients treated in Yingsheng Branch of Taian Central Hospital during Jan.and Oct.2023 were retrospectively analyzed.The perioperative related indicators,incidence of complications were recorded.The international prostate symptoms(IPSS)score,maximum urine flow rate(Qmax),post voiding residual(PVR),quality of life score(QoL),prostate-specific antigen(PSA)level,the Chinese index of premature ejaculation score(CIPE)and international erectile function index-5(IIEF-5)score before operation,and 1,3,6,and 12 months after operation were analyze.Results The operation time was(18.37±5.38)min,intraoperative blood loss(6.73±2.57)mL,postoperative hospital stay(4.31±1.54)d,catheter indwelling time(2.45±1.27)d,and bladder irrigation time(19.61±2.45)h.There were significant differences in Qmax,PVR,PSA level,QoL and IPSS before and after operation(P＜0.05).There was no statistically significant difference in IIEF-5 and CIPE before operation and 3,6 and 12 months after operation(P＞0.05).The retrograde ejaculation rate remained 6.25％3,6 and 12 months after operation.Conclusion The 450 nm blue laser vaporization resection of the prostate can relieve lower urinary tract symptoms,preserve the sexual function,and improve patients'quality of life.

Objective To explore the role of icariin on diabetic osteoporosis(DOP)in rats by regulating estrogen reoeptor 1(ER1).Methods Fifty SD rats were randomly divided into five groups:control,diabetes(STZ),low-dose icariin[four weeks after successful establishment of diabetic model rats,50 mg/(kg·d)icariin was administered by gavage for eight weeks],high-dose icariin[100 mg/(kg·d)icariin administered by gavage for eight weeks],and high-dose icariin+ER1-siRNA group[icariin 100 mg/(kg·d)administered by gavage for eight weeks.A total of 10 μL ER1-siRNA was injected via the tail vein once every four weeks,two times in total],with 10 rats in each group.HE staining was used to detect the pathological morphology of the femoral tissue.Enzyme-linked immunosorbent assay(ELISA)was used to measure serum ALP,TRAP,and blood calcium concentrations.Protein-protein interaction(PPI)network analysis predicted icariin core targets and validated molecular docking.ER1,PDE5A,Wnt,and β-cantenin expression levels in rat femoral tissue were detected using Western blotting.Results In the STZ group,the number of empty lacunae in the subchondral region increased,ALP expression and blood calcium concentration decreased(P＜0.01),and TRAP expression increased(P＜0.01),compared with the control group.In the low-and high-dose icariin groups,blood glucose levels decreased(P＜0.01),the number of empty bone lacunae in the subchondral region decreased,ALP expression and blood calcium concentration increased(P＜0.01),and TRAP expression decreased(P＜0.01),compared with the STZ group.PPI network analysis and molecular docking showed that icariin stably bound to the ER1 protein structure.Com-pared with the control group,expression of ER1,Wnt,and β-cantenin decreased in STZ group(P＜0.01).The expression of ER1,Wnt,and β-cantenin in the high-dose icariin group increased compared with the STZ group(P＜0.01).Moreover,expression of ER 1,Wnt,andβ-cantenin decreased in the high-dose icariin+ER1-siRNA group,compared with the high-dose icariin group(P＜0.01).The protective effects of icariin were reversed by ER1-siRNA administration.Conclusion Icariin could significantly improve osteoporosis in diabetes rats,which may be relevant to the activation of the ER 1-mediated Wnt/β-cantenin pathway.

Objective To compare the clinical efficacy and safety of transurethral 450 nm semiconductor blue laser vaporization enucleation and transurethral resection of bladder tumor(TURBT)in the treatment of non-muscle invasive bladder cancer(NMIBC).Methods The clinical data of 85 NMIBC patients undergoing surgical treatment at Yingsheng Branch of Taian Central Hospital during Dec.2022 and Feb.2024 were retrospectively collected.The patients were divided into the blue laser group(n=40)and TURBT group(n=45).The operation time,intraoperative blood loss,postoperative bladder irrigation time,postoperative catheter indwelling time,postoperative hospital stay,intraoperative complications,wound healing 3 and 6 months after operation,and tumor recurrence 1 year after operation were compared between the two groups.Results Patients in both groups successfully completed the operation without blood transfusion or conversion to open surgery.Compared with the TURBT group,the blue laser group had shorter operation time[(23.68±9.98)min vs.(29.11±14.27)min],less blood loss[(1.43±0.87)g/L vs.(3.27±0.96)g/L],and shorter postoperative bladder irrigation time[0.5(0.5,0.5)d vs.0.5(0.5,1.5)d](P＜0.05).No cases developed obturator nerve reflexes in the blue laser group,but 7 cases in the TURBT group(P＜0.05).Three months after operation,the bladder wounds healed in 24 cases in the blue laser group,but only in 7 cases in the TURBT group(P＜0.01).Conclusion Compared with TURBT,transurethral 450 nm semiconductor blue laser vaporization enucleation for the treatment of NMIBC can shorten the operation time,reduce the amount of bleeding,shorten the postoperative healing time,and cause fewer complications.It is a safe and efficient minimally invasive surgery.

Liver failure is a common severe syndrome of liver diseases with high mortality. The function and structural integrity of the intestinal barrier as an entity are closely associated with the development and progression of liver failure. The cGAS-STING signaling pathway can participate in innate immune response by recognizing DNA produced by pathogen invasion and host cell damage and inducing the production of type I interferon. Numerous studies have shown that activation of the cGAS-STING pathway can significantly impact the cellular structure， mucosal components， and commensal bacteria of the intestinal barrier. This article reviews the interplay between the cGAS-STING signaling pathway and intestinal barrier disruption in liver failure， in order to provide novel insights for the clinical management of liver failure.

After the wooden shipwreck was recovered from the marine underwater environment,the wooden components undergo varying degrees of degradation,therefore,accurately determining the extent of degradation is a fundamental scientific issue for implementing effective preservation strategies.In this work,the wooden remains of Pinus massoniana excavated from the"Nanhai No.1"shipwreck(Southern Song Dynasty)were investigated and compared with the modern wood to discriminate the degradation levels of archaeological wood using attenuated total reflection Fourier transform infrared(ATR-FTIR)spectroscopy.The residual sugar content within wood cell walls was determined using a non-invasive automated microscale ATR-FTIR method to extract chemical information from the wood tangential section.Microstructural characterization of wood samples was conducted by super depth of field microscopy and scanning electron microscopy.FTIR spectral analysis was performed to evaluate the degradation state and elucidate changes in cellulose crystallinity.Finally,the combination of FTIR spectroscopy with the sparse partial least squares discriminant analysis(sPLS-DA)model facilitated the rapid discrimination of degradation levels in shipwreck archaeological wood,and the performance of the model was evaluated using receiver operating characteristic(ROC)curves and area under the curve(AUC).The results showed that the higher the degree of wood degradation,the lower the residual sugar content in the wood cell wall,and the residual glucose content of highly degraded wood was only 4.7％.Significant differences were observed in both the tangential section microstructure and FTIR characteristic absorption patterns across degradation levels,and as the degradation advanced,progressive cell wall loosening occurred alongside selective removal of polysaccharide components,and the relative lignin content was increased,resulting in an elevated A1509/A1370 ratio in FTIR spectra.The sPLS-DA model achieved excellent discrimination performance with AUC values exceeding 0.9,confirming that the combination of FTIR spectroscopy with sPLS-DA enabled accurate assessment of degradation levels in shipwreck archaeological wood.This study developed a rapid and accurate methodology for assessing degradation levels in shipwreck archaeological wood based on microscale ATR-FTIR spectroscopy,which would help to promote the accurate assessment of the preservation state of waterlogged wooden artifacts.
