ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） triple therapy in the treatment of spontaneous bacterial peritonitis （SBP） with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients， and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group， with 43 patients in each group. Both groups received standard western medicine treatment， while the experimental group additionally received TCM triple therapy， including oral Qingre Liangxue Jiedu Decoction （清热凉血解毒汤）， retention enema with Dachengi Decoction （大承气汤）， and abdominal application of Qingre Zhitong Lishui Fomulation （清热止痛利水方） with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment， various indicators were measured， such as TCM syndrome scores， ascites volume measured by abdominal ultrasound， liver function indicators including total bilirubin （TBIL）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and albumin （ALB）， infection markers， including neutrophil percentage （NEUT%）， C-reactive protein （CRP）， and procalcitonin （PCT）， inflammatory factors， such as tumor necrosis factor-alpha （TNF-ɑ）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）， intestinal mucosal barrier function markers， including endotoxin （ET）， diamine oxidase （DAO）， D-lactic acid （D-Lac）， occludin， and zonula occludens-1 （ZO-1）， and peritoneal polymorphonuclear （PMN） cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis， with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% （38/41）， which was significantly higher than the 80.49% （33/41） in the control group （P＜0.05）. Compared with pre-treatment values， both groups showed significant reductions in TCM syndrome scores， ascites volume， TBIL， ALT， AST， NEUT%， CRP， PCT， TNF-α， IL-6， ET， DAO， D-Lac， Occludin， and ZO-1， with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment （P＜0.05）. Furthermore， the experimental group outperformed the control group in all the above indicators after treatment （P＜0.05）. The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group （P＜0.01）. There were no significant changes in routine urine and stool tests， renal function， electrolytes， or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome， alleviates liver inflammation， improves liver function， accelerates the resolution of ascites， and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

Background::Renal ischemia-reperfusion (R-I/R) injury is the most prevalent cause of acute kidney injury, with high mortality and poor prognosis. However, the underlying pathological mechanisms are not yet fully understood. Therefore, this study aimed to investigate the role of N-myc downstream-regulated gene 2 ( Ndrg2) in R-I/R injury. Methods::We examined the expression of Ndrg2 in the kidney under normal physiological conditions and after R-I/R injury by immunofluorescence staining, real-time polymerase chain reaction, and western blotting. We then detected R-I/R injury in Ndrg2-deficient ( Ndrg2-/-) mice and wild type ( Ndrg2+/+) littermates in vivo, and detected oxygen and glucose deprivation and reperfusion (OGD-R) injury in HK-2 cells. We further conducted transcriptomic sequencing to investigate the role of Ndrg2 in R-I/R injury and detected levels of oxidative stress and mitochondrial damage by dihydroethidium staining, biochemical assays, and western blot. Finally, we measured the levels of mitophagy in Ndrg2+/+ and Ndrg2-/- mice after R-I/R injury or HK-2 cells in OGD-R injury. Results::Ndrg2 was primarily expressed in renal proximal tubules and its expression was significantly decreased 24 h after R-I/R injury. Ndrg2-/- mice exhibited significantly attenuated R-I/R injury compared to Ndrg2+/+ mice. Transcriptomics profiling showed that Ndrg2 deficiency induced perturbations of multiple signaling pathways, downregulated inflammatory responses and oxidative stress, and increased autophagy following R-I/R injury. Further studies revealed that Ndrg2 deficiency reduced oxidative stress and mitochondrial damage. Notably, Ndrg2 deficiency significantly activated phosphatase and tensin homologue on chromosome ten-induced putative kinase 1 (PINK1)/Parkin-mediated mitophagy. The downregulation of NDRG2 expression significantly increased cell viability after OGD-R injury, increased the expression of heme oxygenase-1, decreased the expression of nicotinamide adenine dinucleotide phosphate oxidase 4, and increased the expression of the PINK1/Parkin pathway. Conclusion::Ndrg2 deficiency might become a therapy target for R-I/R injury by decreasing oxidative stress, maintaining mitochondrial homeostasis, and activating PINK1/Parkin-mediated mitophagy.

Female acquired urinary incontinence is a clinical challenge. This article reported a female patient who had urinary incontinence after excessive urethral caruncle resection. Urodynamics showed effective urethral length was 1.6 cm and maximal urethral pressure was 41 cm cmH 2O(1 cmH 2O=0.133 kPa). Urethroscopy showed urethral length was about 2 cm, urethral sphincter function was good, and urethral stricture was absent. The patient has undergone robot-assisted modified Leadbetter bladder neck reconstruction. The surgery was successfully completed without intraoperative complications. Urinary catheter was removed at 4 weeks after surgery, and the patient has complete urinary continence with unobstructed voiding. After 3 months of follow-up, the patient still has unobstructed voiding and urinary continence.

Objective:To evaluate the efficacy of robot-assisted Y-V plasty (RAYV) and laparoscopic Y-V plasty (LYV) in the treatment of refractory bladder neck contracture (BNC) after BPH surgery.Methods:A retrospective analysis was performed for the clinical data of 42 patients with refractory BNC after BPH surgery from January 2020 to July 2023, including 18 RAYV and 24 LYV. There were no significant differences between both groups( P>0.05) in term of median age [68(62, 81) years vs. 70(61, 76) years], median body mass index [20.7(17.6, 26.1) kg/m 2 vs. 19.8(16.3, 25.3) kg/m 2], median Q max [9.4(5.6, 13.2) ml/s vs. 8.9(6.2, 12.2)ml/s], median IPSS [20.5(15, 23) vs. 21.1(17, 23)], median QOL score [4.6 (4, 6) points vs. 4.8 (4, 6) points] and median postvoid residual volume [84.7(58, 125)ml vs. 78.3(50, 120)ml]. Preoperative examination of one patient in the RAYV group showed no contractile function of the external urethral sphincter.The surgical procedure was basically the same for both groups: entering into the retropubic space, and incision of the anterior wall of bladder and prostate urethra was performed in an inverted Y-shaped. After excising the scar around the anterior wall of bladder neck, the apex of inverted V-shaped bladder wall flap is brought to the base of the Y-shaped incision using two 3-0 running suture. The catheter was removed 2 weeks after surgery. Perioperative and follow-up data were compared between the two groups. Results:All surgeries were successfully completed without complications. The difference between RAYV and the LYV group in operation time [71.8(50, 98)min vs. 105.9(71, 143)min] and postoperative drainage removal time [2.7(2, 4)d vs. 4.5(3, 7)d] was statistically significant ( P<0.05). There was no significant difference between both groups in term of intraoperative blood loss [50.4(20, 100) ml vs. 60.8(40, 150) ml] and postoperative hospital stay [4.1(3, 5)d vs. 4.6(3, 7)d]( P>0.05). All patients were followed up with a median follow-up of 16.5(2, 41) months. There was no significant difference between RAYV and LYV in term of postoperative Q max [27.9(11.7, 37.6) ml/s vs. 22.4(12.3, 31.5)ml/s], IPSS[5.1(4, 9) points vs. 4.8(4, 10) points], QOL[1.6(1, 3) points vs. 1.5(1, 3) points] and postvoid residual volume [5.6(0, 15) ml vs. 7.2(5, 20) ml] ( P>0.05). The postoperative bladder neck patency rates in the RAYV group and the LYV group were 94.4%(17/18) and 95.8%(23/24), respectively, with no significant difference( P>0.05). In terms of urinary continence, 1 patient in the RAYV group had no contractile function of the external urethral sphincter before surgery, and none of the 41 patients with good preoperative continence had urinary incontinence after surgery. Conclusions:The effect of RAYV in the treatment of refractory BNC after BPH surgery is comparable to that of LYV, but RAYV can shorten the operation time and postoperative drainage time.

Pelvic fracture urethral injury (PFUI) may result in loss of external urethral sphincter function, and traditional transurethral resection of the prostate may increase risk of permanent urinary incontinence after surgery in patients with benign prostatic hyperplasia (BPH) with a history of PFUI reconstruction. In the study, hulium laser enucleation-resection of prostate(ThuLERP) with bladder neck preservation was used to treat 4 patients with BPH with a history of PFUI reconstruction. All operations were conducted smoothly, and all patients had unobstructed voiding and no permanent urinary incontinence at 3 months after surgery. ThuLERP with bladder neck preservation was safe and effective treatment of BPH with a history of PFUI reconstruction, and avoided the risk of permanent urinary incontinence.

The paper summarizes the treatment experience of surgical repair combined with automated peritoneal dialysis in a maintenance peritoneal dialysis patient complicated with thoracoabdominal fistula. Through the close participation of medical and patients, the diagnosis method and peritoneal dialysis scheme were optimized continuously. The thoracoabdominal fistula repair operation was successfully implemented by a multidisciplinary team, and the patient's condition was improved and was discharged. This case suggests that standardized diagnosis process and optimized diagnosis method can be applied to improve the sensitivity and specificity of diagnosis, and strive for early diagnosis and intervention; multi-disciplinary teams can be actively formed and the patients can be encouraged to participate in decision-making, to improve treatment confidence; the advantages of automated peritoneal dialysis can be made full use to reduce complications and improve the life quality of the patient.

The treatment of ventral and incisional hernias has progressed from simple repair and reinforcement to reconstruction,restoration,and regeneration.There are Onlay,Sublay,preperitoneal,intraperitoneal repair planes,and each plane could be performed via open or laparoscopic surgery.Laparoscopic surgery mainly includes intraperitoneal onlay mesh(IPOM)and minimally invasive non-intraperitoneal mesh(MINIM)repair.Regardless of the technique applied,it is essential to follow the principles of abdominal wall functional reconstruction and minimally invasive features to demonstrate their clinical value.The core of abdominal wall functional reconstruction in laparoscopic surgery for ventral and incisional hernias could be summarized as restoring Anatomical structure,protecting Biomechanics,maintaining Compliance,and providing overall Dynamic support for the body.

ObjectiveTo reveal the effects of Huanglian Jiedutang （HLJDT） on the learning and memory abilities of APP/PS1 transgenic mice via hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF） signaling pathway. MethodForty 5-month-old β-amyloid precursor protein （APP）/presenilin 1（PS1） mice were randomized into the model， donepezil （0.001 g·kg^-1·d^-1）， and low-， medium-， and high-dose （1.5， 3， 6 g·kg^-1·d^-1， respectively） HLJDT groups， and 8 C57BL/6 mice were taken as the normal group. After 45 days of continuous administration， Morris water maze test was conducted， and the organ indexes were calculated. The morphological structure of cerebral vascular endothelial cells in mice was observed under a transmission electron microscope. Western blot was employed to measure the protein levels of APP， HIF-1α， VEGF，VEGFA， and brain-derived neurotrophic factor （BDNF） in the hippocampus. The mRNA levels of APP， HIF-1α， and VEGF were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the normal group， the model group showed prolonged escape latency （P<0.05）， reduced distance and time around the target platform （P<0.05）， decrease brain and spleen indexes （P<0.05）， vascular endothelial cells with karyopyknosis and not abundant cytoplasm， up-regulated protein levels of APP， HIF-1α， VEGF， and VEGFA （P<0.05）， down-regulated protein level of BDNF （P<0.05）， and up-regulated mRNA levels of APP， HIF-1α， and VEGF （P<0.05） in the hippocampus. Compared with the model group， high-dose HLJDT shortened the escape latency （P<0.05）， increased the distance and time around the target platform （P<0.05）， raised the brain and spleen indexes （P<0.05）， repaired the organelles of vascular endothelial cells， down-regulated the protein levels of APP， HIF-1α， VEGF， and VEGFA （P<0.05）， up-regulated the protein level of BDNF （P<0.05）， and down-regulated the mRNA levels of APP， HIF-1α， and VEGF （P<0.05） in the hippocampus. ConclusionHLJDT can improve the learning and memory abilities of mice by reducing the expression of HIF-1α and VEGF， thus protecting the nerves.

Breast cancer is one of the most common cancers in women,but there is currently a lack of accurate prognos-tic assessment systems.The Naples Prognostic Score(NPS)is a prognostic prediction system that incorporates inflammatory and nutritional indicators.It has been proven to have important clinical utility in predicting the prognosis of patients with malignancies such as colon cancer,gallbladder cancer,endometrial cancer,and lung cancer.In recent years,research has found that NPS may be superior to TNMstaging in predicting the prognosis of breast cancer patients.It is an independent predictor of overall sur-vival(OS)and progression-free survival(PFS)in breast cancer patients.This suggests that NPS has great potential for applica-tion in predicting the prognosis of breast cancer.
