This study aims to investigate the anti-inflammatory and anti-apoptotic effects of total flavonoids of hawthorn leaves(TFHL)on lipopolysaccharide(LPS)-induced inflammatory injury in rat intestinal epithelial(IEC-6)cells,as well as the underlying mechanisms.An in vitro inflam-mation model was first established by treating IEC-6 cells with lipopolysaccharide(LPS).IEC-6 cells were then incubated with three concentrations of TFHL for 24 h prior to a further 24 h LPS treatment.RT-qPCR was used to quantify mRNA levels of the inflammatory genes COX-2 and iN-OS,while Western blotting was used to assess protein levels of the apoptotic markers Bax,cleaved Caspase-3,Bcl-2,and the JNK/p-JNK signaling pathway.Finally,cells were pretreated with TFHL and/or the JNK inhibitor SP600125 for 24 h before LPS exposure for 24 h,in order to evaluate the combined effects of TFHL and SP600125 on LPS-induced inflammatory cytokine expression and apoptotic protein levels in IEC-6 cells.The results showed that,compared with the LPS group,the mRNA level of COX-2 and iNOS in the 2.5,5.0,10.0 mg/L TFHL group and the Bax and Caspase-3 protein levels decreased significantly(P<0.01),and the Bcl-2 protein level was significantly higher(P<0.01),p-JNK protein level and p-JNK/JNK ratio decreased significantly(P<0.01);compared with the LPS group,the COX-2 and iNOS mRNA levels of the TFHL+LPS group de-creased significantly(P<0.01),Bax,and Caspase-3 protein levels decreased significantly(P<0.01),and the level of Bcl-2 protein increased significantly(P<0.05);compared with the LPS group,the COX-2 and iNOS mRNA levels of the TFHL+SP600125 group decreased significantly(P<0.01),Bax and Caspase-3 protein levels decreased significantly(P<0.01),and Bcl-2 protein level increased significantly(P<0.01).These findings indicate that TFHL exerts anti-inflammato-ry and anti-apoptotic effects in LPS-challenged IEC-6 cells by inhibiting the JNK signaling path-way.

Objective:To evaluate the safety and efficacy of transtobturator urethral sling operation in the treatment of male stress urinary incontinence.Methods:A retrospective analysis was conducted on the clinical data of 13 male patients with stress urinary incontinence who underwent transvaginal sling procedure at Peking University People's Hospital from June 2011 to July 2024. The patients' average age was (71.6±5.4) years. Among them, 9 patients had undergone radical prostatectomy, and 4 had undergone transurethral resection of the prostate (TURP). Of the 13 patients, 7 had moderate urinary incontinence, and 6 had severe urinary incontinence. The median daily number of urine pads used by the 13 patients before surgery was 5 (3, 8), and the median score of the Incontinence Quality of Life Questionnaire (I-QOL) was 16 (12, 28). The median score of the Male Stress Urinary Incontinence Grading Scale (MSIGS) was 2 (2, 3). All the 13 patients underwent transvaginal sling procedure. The patients were placed in the lithotomy position, and the urethral bulb was dissected anatomically beneath the scrotum. The sling was guided by a needle and pulled out through the obturator foramen, and placed over the urethral bulb. The sling was tightened and the tension adjusted to fully suspend the urethra. A urinary catheter was left in place for 1-7 days after surgery. The patients' postoperative daily use of urine pads, scores of the I-QOL and MSIGS, and postoperative complications were followed up.Results:Postoperative follow-up ranged from 2 to 139 months, with a median follow-up time of 12 months. Of the 13 patients, 2 were cured, 9 had improved and 2 had no significant improvement. The number of diapers used per day by patients postoperatively was 1 (1, 4) pieces, the I-QOL score was 75 (46, 82), and the MSIGS score was 1 (0, 2), which were all significantly improved compared to preoperative values ( P<0.01). Among the 6 severe stress urinary incontinence patients who were followed up, the number of diapers used per day was significantly reduced compared to preoperative values[ 2(1, 5) vs. 8(7, 8) pieces], and the I-QOL score was significantly improved [ 60(35, 70) vs. 12(10, 16) ], while the MSIGS score was significantly lower [ 2(1, 3) vs. 3(2, 4) ]. Among the 7 moderate stress urinary incontinence patients, the number of diapers used per day was significantly reduced compared to preoperative values [1 (0, 1) vs. 4 (4, 5) pieces], and the I-QOL score was significantly improved [ 80(75, 82) vs. 21(18, 30) ], while the MSIGS score was significantly lower [ 0 (0, 1) vs. 2 (2, 3) ]. The symptoms of 1 patient were not significantly improved after the surgery, and were improved after Virtue sling suspension 3 years later. Conclusions:The use of transtobturator urethral sling operation for the treatment of moderate to severe male stress urinary incontinence has shown clear efficacy, with a low incidence of postoperative complications.

Based on the discussions in the The Inner Canon of Yellow Emperor (《黄帝内经》), it is proposed that in the course of the disease, "bind" represents the initial stage of pulmonary nodules, while "accumulation" represents the final form. In terms of the pathogenesis, "two colds interacting" represented by "body cold" and "cold fluid retention" are the prerequisites for the formation of pulmonary nodules, while "disorder of qi" represented by "fainting" is the core of the formation. The specific manifestation is the disturbance of pivot of shaoyang (少阳) or shaoyin (少阴), resulting in a complex of cold and heat, and then phlegm and stasis are suddenly generated and further formed into nodules. Therefore, the treatment principle should be to regulate the cardinal mechanism, dissolve phlegm and blood stasis. Depending on the complex degree of cold and heat, it is suggested to use Chaihu Guizhi Decoction (柴胡桂枝汤), Chaihu Guizhi Ganjiang Decoction (柴胡桂枝干姜汤), or Chaihu Xianxiong Decoction (柴胡陷胸汤) for disturbance of shaoyang pivot, while for shaoyin pivot dysfunction, modified Mahuang Fuzi Xixin Decoction (麻黄附子细辛汤) or Shengjiang Powder (升降散) can be used.

[Objective] To explore the expression of Nectin-4 in invasive bladder urothelial carcinoma (BUC) tissue and its clinical significance, so as to provide reference for clinical diagnosis and treatment of BUC. [Methods] Nectin-4 expression in 60 cases of invasive BUC and 40 cases of chronic inflammation of bladder mucosa was detected with immunohistochemical staining (IHC) and RNAscope.The results of the two methods were analyzed and compared, and the relationship between the two methods and the clinicopathological characteristics of invasive BUC was discussed.The correlation between the protein expression of Nectin-4 in BUC tissues, human epidermal growth factor receptor 2 (Her-2) and programmed death factor ligand 1 (PD-L1) was analyzed. [Results] The positive protein expression rates of Nectin-4 detected by IHC were 78.33%(47/60) and 17.50% (7/40) in the invasive BUC group and inflammatory group, respectively, while the positive mRNA expression rates of Nectin-4 detected by RNAscope were 83.33% (50/60) and 12.50% (5/40), respectively.The Kappa values of Nectin-4 in the invasive BUC group and inflammatory group were 0.732 and 0.610, respectively, with general consistency.The protein expression of Nectin-4 in invasive BUC was correlated with muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The mRNA expression of Nectin-4 in invasive BUC was correlated with max tumor diameter, muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The high expression of Nectin-4 in invasive BUC was positively correlated with the expression of Her-2 (P=0.002), but not with the expression of PD-L1 (P>0.05). [Conclusion] Nectin-4 is highly expressed in invasive BUC, and is usually associated with the pathological parameters of poor prognosis.Detection of Nectin-4 expression will help to guide clinical diagnosis and treatment.
