Objective To compare the short-term clinical effects of unilateral dual-channel endoscopic discectomy(UBED)and percutaneous endoscopic intervertebral discectomy(PEID)in the treatment of L5S,Lumbar disc herniation,LDH.Methods From January 2019 to January 2021,a total of 57 cases of L5S,LDH treated by UBED or PEID were analyzed retrospectively,including 30 cases in UBED group and 27 cases in PEID group.The operation time,intraoperative fluoroscopy times,postoperative hospitalization days and surgical complications were compared between the two groups.The visual analogue scale(VAS)and oswestry disability index(ODI)were used to compare the postoperative quality of life of the two groups,and the modified MacNab criteria was used to evaluate the clinical efficacy in the last follow-up.Results The operation time of UBED group and PEID group was(75.30±8.44)minutes and(68.37±4.63)minutes,respectively,and the difference between the two groups was statistically significant(P＜0.05).VAS and ODI of 1 week,3 months,1 year and 1.5 years after surgery in 2 groups were significantly decreased compared with those before surgery,with statistical significance(P＜0.05).The VAS score of low back pain in UBED group was higher than that in PEID group[(3.87±1.14)points vs(2.70±0.67)points]at 1 week after surgery(P＜0.05),and there was no significant difference in VAS and ODI at the other time points(P＞0.05).There was no statistical difference in the results of modified MacNab criteria in the last follow-up(P＞0.05).There were 2 cases of dural tear in PEID group,1 case of dural tear in UBED group and 1 case of temporary nerve root injury in PEID group after operation,all of which were cured after symptomatic treatment.Conclusion Compared with PEID,UBED has a longer operation time,more trauma and more obvious low back pain in the short term after operation.The short-term curative effect of the two operations on L5S1 LDH is similar,the incidence of complications is low,and the times of fluoroscopy are few.Both operations are safe and effective.

Objective:To investigate the effect of sertraline hydrochloride combined with compound chamomile lidocaine gel in the treatment of premature ejaculation(PE).Methods:We selected 80 cases of PE treated in our hospital from June 2021 to May 2023 and equally randomized them into a control and an observation group,the former medicated with compound chamomile lidocaine gel while the latter with sertraline hydrochloride in addition,both for 6 weeks.We recorded and compared the intravaginal ejaculation latency time(IELT),the number of successful sexual intercourses per week,the Premature Ejaculation Diagnostic Tool(PEDT)scores,and the incidence of adverse reactions between the two groups of patients.Results:After the treatment,the IELT was signif-icantly longer([5.39±1.17]vs[2.49±0.73]min,P＜0.05),the weekly number of successful sexual intercourses remarkably higher(1.82±0.45 vs 0.93±0.19,P＜0.05)and the PEDT scores markedly lower(7.42±2.04 vs 9.85±2.36,P＜0.05)in the observation than in the control group,but no statistically significant differences were observed in the baseline PEDT scores or the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Sertraline hydrochloride combined with com-pound chamomile lidocaine gel is definitely effective in the treatment of PE,which can significantly improve the patients'quality of sexual life,with a high safety and low incidence of adverse reactions.

Objective: This study compared the outcomes of laparotomic radical hysterectomy (LRH) and minimally invasive radical hysterectomy (MISRH) in patients with early-stage cervical cancer. Methods: The clinical data of patients with early-stage cervical cancer who underwent LRH or MISRH (laparoscopic/robotic) at Chang Gung Memorial Hospital, Linkou Branch, from 2002 to 2017 were retrospectively reviewed. The surgical safety (operation time, blood loss, blood transfusion rate, length of postoperative stay, and perioperative complications), overall survival (OS), disease-free survival (DFS), and recurrence pattern were analyzed. Propensity score matching (PSM) at a 3:1 ratio was performed to balance prognostic variables. Results: Of the 760 patients (entire cohort), 614 underwent LRH and 146 underwent MISRH.After PSM, 394 and 140 patients were included in the LRH and MISRH groups, respectively.The 5-year OS rate was significantly lower in the MISRH group than in the LRH group (85.6% vs. 93.2%, p=0.043), and the 5-year DFS rate (p=0.21) did not differ significantly. After PSM, the 5-year OS rates did not differ significantly between the MISRH and LRH groups (87.1% vs. 92.1%, p=0.393). The MISRH group had a significantly shorter operation time (p<0.001), lower intraoperative blood loss (p<0.001), lower blood transfusion rate (p<0.001), and shorter postoperative stay (p<0.001) but a significantly higher rate of intraoperative bladder injury (p<0.001) than the LRH group. Conclusion After PSM, MISRH is associated with nonsignificantly lower OS but a significantly higher risk of intraoperative urological complications than LRH.

This study primarily investigated the mechanism of Astragalus polysaccharides(APS), a Chinese medicinal material, in regulating the Nrf2/SLC7A11/GPX4 signaling pathway to induce ferroptosis in ovarian cancer cells(Caov-3 and SKOV3 cells). Caov-3 and SKOV3 cells were divided into control(Vehicle) group, APS group, glutathione peroxidase 4 inhibitor(RSL3) group, and APS+RSL3 group. After 48 h of intervention, the activity and morphology of the cells in each group were observed. The cell counting kit-8(CCK-8) method was used to determine the half-maximal inhibitory concentration(IC_(50)), while colony formation and EdU assays were conducted to assess cell proliferation. Biochemical reagents were used to detect lipid reactive oxygen species(L-ROS), malondialdehyde(MDA), divalent iron ions(Fe~(2+)), and glutathione(GSH) in Caov-3 cells. Transmission electron microscopy was employed to observe the morphological changes of mitochondria in Caov-3 cells. Bioinformatics analysis were used to screen potential target genes of APS in ovarian cancer cells. Western blot and RT-PCR were applied to measure the protein and mRNA expression of Nrf2, SLC7A11, and GPX4. The results revealed that APS effectively inhibited the activity and proliferation of ovarian cancer cells, significantly increased the expression levels of L-ROS, MDA, and Fe~(2+)(P<0.001), and significantly reduced the expression level of GSH(P<0.001). Under electron microscopy, the mitochondria of Caov-3 cells appeared significantly smaller, with a marked increase in the density of the bilayer membrane, disappearance of mitochondrial cristae, and rupture of the outer mitochondrial membrane. These effects were more pronounced when APS was combined with RSL3. Bioinformatics screening identified Nrf2, SLC7A11, and GPX4 as potential target genes for APS in ovarian cancer cells. APS was shown to reduce the protein and mRNA expression of Nrf2, SLC7A11, and GPX4(P<0.01), with the APS+RSL3 showing even more significant effects(P<0.001). In conclusion, APS can induce ferroptosis in ovarian cancer cells, and its mechanism may be related to the regulation of the Nrf2/SLC7A11/GPX4 signaling pathway, providing an experimental basis for the use of APS injections in the treatment of ovarian cancer.
