Interleukin-17 (IL-17) and its receptor family members are involved in a variety of pathophysiological processes.Studies have shown that the IL-17 family may be closely related to the occurrence and development of interstitial cystitis/ bladder pain syndrome (IC/BPS).This paper explores the relationship between the IL-17 family and IC/BPS, introduces the members and structures of the IL-17 family, their value in inflammatory diseases, and discusses in depth the IL-17 pathways in IC/BPS and the latest research progress.Research has found that the IL-17 family is upregulated in IC/BPS, related to the exacerbation of pathological inflammatory reactions, and responsible for maintaining the chronic inflammatory state of IC/BPS patients.In addition, IL-17 is also associated with neuroinflammation, pain, and other biological effects in IC/BPS.This review aims to deepen the understanding of the mechanisms underlying IC/BPS and to provide references for the development of new therapeutic strategies.

BACKGROUND:As a common complication of diabetes mellitus,male reproductive disorders have received increasing attention in recent years.Ganoderma spore have hypoglycemic,antioxidant and anti-inflammatory effects,but the regulatory mechanism for diabetic testicular tissue has not been fully elucidated. OBJECTIVE:To investigate the effect of ganoderma spore on the PTEN-induced kinase 1/E3 ubiquitin ligase pathway and cell apoptosis in testicular tissue of diabetic rats. METHODS:Forty male Sprague-Dawley rats were randomly divided into normal group,high fat and high sugar group,diabetic group and ganoderma spore group,with 10 rats in each group.The latter three groups were given high fat/high sugar diet until the end of the experiment.After 1 month of high fat/high sugar diet,the diabetic and ganoderma spore groups were given intraperitoneal injection of streptozotocin(30 mg/kg per day)to establish type 2 diabetic rat models.After successful modeling,the ganoderma spore group was intragastrically given ganoderma spore(300 mg/kg per day),and the other groups were given the same amount of normal saline for continuous 12 weeks.The sperm number and morphology were detected.The histopathological changes of the testicle were observed.Serum testosterone and oxidative stress levels in testicular tissue were measured.The levels of PTEN-induced kinase 1,E3 ubiquitin ligase,and anti-nucleoporin p62 were analyzed by immunohistochemistry and the expression of PTEN-induced kinase 1,E3 ubiquitin ligase,anti-nucleoporin p62,programmed cell death-1,microtubule-associated protein light chain 3 Ⅱ/Ⅰ,caspase 3,cleaved-caspase 3 were detected by western blot assay. RESULTS AND CONCLUSION:Compared with the normal group and the high fat and high sugar group,the diabetic group had decreased sperm number(P＜0.01),increased sperm malformation rate(P＜0.01),and decreased serum testosterone level(P＜0.01).Compared with the diabetic group,ganoderma spore intervention could increase the sperm number(P＜0.05),decrease the malformation rate(P＜0.01),and increase the serum testosterone level(P＜0.01).Compared with the normal group and the high fat and high sugar group,the malondialdehyde level in testis tissue was increased in the diabetic group(P＜0.01),while the levels of glutathione deoxidase and superoxide dismutase decreased(P＜0.01).Compared with the diabetic group,the malondialdehyde level in testis tissue was decreased in the ganoderma spore group(P＜0.01),and the levels of glutathione deoxidase and superoxide dismutase increased(P＜0.01).Immunohistochemical staining showed that compared with the normal group and the high fat and high sugar group,the positive expressions of PTEN-induced kinase 1 and E3 ubiquitin ligase in testicular tissue were decreased in the diabetic group,while the positive expressions of anti-nucleoporin p62 were increased.Compared with the diabetic group,the positive expressions of PTEN-induced kinase 1 and E3 ubiquitin ligase in testicular tissue e were increased in the ganoderma spore group,while the positive expression of anti-nucleoporin p62 was decreased.Western blot assay results indicated that compared to the normal group and the high fat and high sugar group,the expression of PTEN-induced kinase 1 and E3 ubiquitin ligase,programmed cell death-1 and the ratio of microtubule-associated protein light chain 3 Ⅱ/Ⅰ protein were decreased in the diabetic group(P＜0.05 or P＜0.01),while the expressions of anti-nucleoporin p62,caspase3 and cleaved-caspase3 were increased(P＜0.01).Compared with the diabetic group,ganoderma spore intervention could elevate the expression of PTEN-induced kinase 1 and E3 ubiquitin ligase,programmed cell death-1 and the ratio of microtubule-associated protein light chain 3 Ⅱ/Ⅰ protein(P＜0.05 or P＜0.01)as well as reduce the expressions of anti-nucleoporin p62,caspase3 and cleaved-caspase3(P＜0.05 or P＜0.01).Overall,ganoderma spores may activate the PTEN-induced kinase 1/E3 ubiquitin ligase pathway to enhance autophagy in testicular tissue and reduce apoptosis in tissue cells,so as to protect testicular tissue.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Objective:To explore the factors influencing lymph node metastasis and prognosis in patients with Siewert type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction (AEG).Methods:A retrospective analysis was conducted on clinical data of 239 patients with Siewert Type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction who underwent surgical treatment at Beijing Friendship Hospital, Capital Medical University, from July 2013 to December 2022. Among them, there were 204 males and 35 females. The patients′ ages ranged from 27 to 83 years, with a mean age of 63.1 years. Statistical analysis was performed using SPSS 26.0 software, with categorical data presented as n(%) and compared using χ2 tests, corrected χ2 tests, or Fisher′s exact tests. Ordinal data were expressed as frequencies and percentages and compared using rank-sum tests. Multivariate analysis was conducted using Logistic regression, and survival analysis was performed using the Cox regression model. Follow-up was conducted every 6 months, with the last follow-up conducted in November 2023. Results:Multivariate analysis identified infiltration depth ( OR=0.038, 95% CI: 0.011-0.139, P<0.001), tumor deposit ( OR=0.101, 95% CI: 0.011-0.904, P=0.040) and intravascular cancer embolus ( OR=0.234, 95% CI: 0.108-0.507, P<0.001) as independent predictors of LNM. Lymph nodes No. 1, 2, 3, 4, 7, 10, and 11 were more prone to metastasis in the abdominal cavity. Notably, Siewert Ⅲ AEG patients showed a higher metastatic rate in nodes No. 5 and No. 6 compared to Siewert Ⅱ. Mediastinal LNM was predominantly found in nodes No. 110 and No. 111 for Siewert Ⅱ AEG, with rates of 5.45% and 3.64%, respectively. A three-year survival analysis underscored LNM as a significant prognostic factor ( P=0.001). Conclusions:Siewert Ⅱ AEG patients should undergo removal of both celiac and mediastinal lymph nodes, specifically nodes No. 1, 2, 3, 4, 7, 10, 11, 110, and 111. Dissection of nodes No. 5 and No. 6 is not indicated for these patients. In contrast, Siewert Ⅲ AEG patients do not require mediastinal LND, but pyloric lymphadenectomy for nodes No.5 and No.6 is essential. The presence of LNM is associated with poorer long-term prognosis. Perioperative chemotherapy may offer a survival advantage for AEG patients.

Objective:To explore the perioperative safety and postoperative short-and long-term efficacy of stomach-partitioning gastrojejunostomy (SPGJ) with distal selective vagotomy (DSV) for treating benign gastric outlet obstruction (GOO).Methods:The clinical data of 26 benign GOO patients treated by Beijing Friendship Hospital, Capital Medical University from January 2019 to July 2023 were retrospectively analyzed. There were 20 males (76.9%) and 6 females (23.1%), aged from 25 to 75 years, with an average age of (55.8±13.6) years, and an average body mass index (BMI) of (20.1±3.4) kg/m 2. There were 12 cases in SPGJ-DSV group and 14 cases in SPGJ group. The main outcome was the gastrointestinal quality of life index (GIQLI) 1 year after surgery in both groups. Independent sample t-test was used to test the difference between the continuous variables with normal distribution. The comparison between groups of non-normal distribution continuous variables was tested by Mann-Whitney U test. Counting data were compared using Chi-square test or Fisher exact test. Results:There were no significant differences between the two groups in terms of operative time ( P=0.071), intraoperative blood loss ( P=0.422), time to pass gas ( P=0.538), time to liquid intake ( P=0.386), postoperative hospitalization ( P=0.431), complications within 30 days after surgery ( P=0.999), and postoperative GOOSS grade ( P=0.483). Among them, postoperative DGE occurred in one patient in each of the two groups, both of which were grade A. In the follow-up results, compared with the SPGJ group, SPGJ-DSV group had a significant advantage in GIQLI score, and the difference was statistically significant ( P=0.028). The incidence of gastric ulcer, reflux esophagitis, bile reflux and gastritis in SPGJ-DSV group was 8.3%, 8.3%, 8.3% and 58.3%, while that in SPGJ group was 35.7%, 21.4%, 21.4% and 57.1%, respectively, but there was no statistical significance between groups. Conclusion:In the treatment of benign GOO patients, SPGJ with DSV did not significantly increase the difficulty of laparoscopic procedures, operative time and intraoperative blood loss. Moreover, it showed a significant advantage in gastrointestinal quality of life 1 year after surgery. In addition, the incidence rates of gastric ulcers and reflux esophagitis were lower in the SPGJ-DSV group 1 year after surgery, but further confirmation is needed in large sample studies.

Objective:To compare the clinical efficacy of ultrasound-guided spinal nerve block (SNB) and paraverteral nerve block (PVB) in treating postherpetic neuralgia.Methods:A total of 52 patients with postherpetic neuralgia who visited the Pain Clinic of the Xiangya Hospital, Central South University from February 2020 to December 2022 were selected and randomly divided into an ultrasound-guided SNB group and a PVB group using a random number table method, with 26 patients in each group. Patients in the SNB group received ultrasound-guided spinal nerve block therapy; The PVB group received ultrasound-guided paraverteral nerve block treatment. Visual Analog Scale (VAS) scores, 36-Item Short Form Survey (SF-36) scores, and total effective rate were observed in two groups of patients before treatment, 2 weeks after treatment, 1 month after treatment, 3 months after treatment, and 6 months after treatment. Complications during treatment were also observed.Results:The total effective rates of SNB group patients at 1, 3, and 6 months after treatment were significantly higher than those of PVB group (all P<0.05). After treatment, the VAS scores of both groups of patients at each time point were significantly reduced compared to before treatment (all P<0.05); The VAS scores of patients in the SNB group were lower than those in the PVB group at 1, 3, and 6 months after treatment, but the difference was not statistically significant (all P>0.05). There was no statistically significant difference in Physical Component Summary (PCS) and Mental Component Summary (MCS) scores between SNB and PVB groups before nerve block treatment (all P>0.05). The MCS and PCS scores of the two groups of patients were significantly higher than before treatment at 2 weeks, 1 month, 3 months, and 6 months after treatment (all P<0.05). The MCS scores of the SNB group were significantly higher than those of the PVB group at 2 weeks, 1 month, 3 months, and 6 months after treatment (all P<0.05), but there was no statistically significant difference in PCS scores between the two groups (all P>0.05). Both groups of patients did not experience any serious complications related to the treatment in this study during the follow-up period. Conclusions:Both ultrasound-guided spinal nerve block and paraverteral nerve block can safely and effectively treat postherpetic neuralgia. The clinical effect of ultrasound-guided spinal nerve block in treating postherpetic neuralgia is better than that of paraverteral nerve block.

Objective:To investigate the effect of astragaloside A (AS-A) on the photoreceptor degeneration induced by sodium iodate (NaIO 3) and its related mechanism. Methods:Sixty healthy male C57BL/6J mice, aged 6-8 weeks, were randomly divided into normal control (NC) group, NaIO 3 group, and ASA group, with twenty mice in each group. 30 min before modeling, AS-A group mice were intraperitoneally injected with 100 μl AS-A at a dose of 100 mg/kg body weight. 30 min later, mice in NaIO 3 group and AS-A group were intraperitoneally injected with 100 μl NaIO 3 at a dose of 30 mg/kg body weight. Subsequently, AS-A group mice were administered AS-A twice daily at 12 h intervals until the end of the experiment. On day 1 post-modeling, zonula occludens-1 (ZO-1) immunohistochemistry was performed to observe the structure of retinal pigment epithelium (RPE) cells; real-time quantitative polymerase chain reaction (qPCR) was conducted to detect the mRNA expression of various retinal chemokine ligand-2 ( Ccl2), interleukin-1 beta ( Il-1β), mixed lineage kinase domain-like protein ( Mlkl), receptor-interacting protein kinase 3 ( Ripk3), and tumor necrosis factor ( Tnf). On day 3 post-modeling, immunohistochemistry was performed to observe the expression of ionized calcium binding adaptor molecule 1 (Iba1) and glial fibrillary acid protein (GFAP) in the retina; TdT-mediated dUTP nick-end labeling (TUNEL) assay was used to detect photoreceptor cell death in each group. On day 4 post-modeling, fundus morphology of mice in each group was observed by fundus color photography and optical coherence tomography (OCT). Hematoxylin-eosin staining (HE) was used to observe the morphological structure of the retina in each group. Inter-group comparisons between two groups were conducted using independent samples t-test, while comparisons among three groups were performed using one-way ANOVA. Results:Fundus color photography and OCT examination showed that a large number of scattered yellow-white subretinal nodular structures in the fundus of NaIO 3 group mice, and a large number of strong reflection areas in the RPE layer. The number of strong reflection areas in the RPE layer was reduced in the AS-A group. Immunohistochemical analysis of ZO-1 showed that ZO-1 was largely lost on the RPE cell membrane in that NaIO 3 group; whereas in the AS-A group, ZO-1 was evenly distributed on the RPE cell membrane. HE staining results showed circular black deposits were visible in the RPE layer of the NaIO 3 group, and the inner and outer segments of photoreceptors were severely damaged, with a significant decrease in the number of outer nuclear layer (ONL) cell nuclei; whereas in the AS-A group, the RPE layer pigments were orderly, the inner and outer segments of photoreceptors were intact, and the number of ONL cell nuclei significantly increased. The results of TUNEL staining show that numerous TUNEL-positive cell nuclei were observed in the ONL of the retina in the NaIO 3 group, while the number of TUNEL-positive cell nuclei in the ONL of the retina was significantly reduced in the AS-A group, with statistically significant differences ( t=2.66, P<0.05). The analysis of qPCR data showed that compared with the AS-A group, the relative expression levels of Mlkl, Ripk3, Ccl2, Il-1β and Tnf mRNA in the retina were significantly increased in the NaIO 3 group, with statistically significant differences ( F=39.18, 10.66, 53.51, 41.40, 24.13; P<0.001). Immunohistochemical staining results showed that compared with NC group and AS-A group, the positive expression of GFAP in retina of NaIO 3 group was significantly increased, and the difference was statistically significant ( F=9.62, P<0.05). Conclusion:AS-A antagonizes NaIO 3-induced photoreceptor degeneration in part by inhibiting photoreceptor cell death and neuroinflammation. Meanwhile, AS-A treatment protects against NaIO 3-triggered perturbation of retinal homeostasis.

Objective:To establish a three-dimensional model of locking plate fixation for 42A2 type oblique tibial fractures with different fracture line directions and different angles between the fracture line and the long axis of the tibia. Finite element analysis was used to calculate and analyze the biomechanics of locking plate, screw, and tibia, providing theoretical basis for clinical application.Methods:A healthy adult volunteer, 25 years old, male, with a height of 173 cm and a weight of 69.5 kg, was selected to perform computed tomography (CT) scans on the left tibia. Relevant data were obtained to establish a locking steel plate fixation model for 42A2 type tibia with different oblique fracture line directions and different angles between the fracture line and the long axis of the tibia. Eight hole pure titanium plates were used for fixation, respectively. We compared the Mises stress changes of locking plates, screws, and tibia in different angle fracture models.Results:In the case of a 42A2 type fracture in the left oblique direction with a fracture line from outside to inside, the maximum Mises stress in the tibia was 114 MPa, the maximum Mises stress in the screw was 279.8 MPa, and the maximum Mises stress in the locking steel plate was 302.4 MPa; In the case of a 42A2 type fracture in the right oblique fracture with a fracture line from the bottom to the top, the maximum Mises stress of the tibia was 93.41MPa, the maximum Mises stress of the screw was 353.4 MPa, and the maximum Mises stress of the locking steel plate was 411.8 MPa.Conclusions:Regardless of the oblique fractures in both left and right directions, the maximum stress values are: locking plate>screw>tibia; When the position of the locking steel plate is fixed, the maximum stress values of the locking steel plate and screw are both right oblique fracture>left oblique fracture; And the maximum stress values all increase with the increase of angle.
