Objective:To investigate the safety and feasibility of one-stage flexible ureteroscopic lithotripsy without ureteral access sheath or ureteral stent in the treatment of upper ureteral calculi and renal calculi with a long diameter of≤10 mm.Methods:A total of 70 patients with upper ureteral calculi or renal calculi with a long diameter of≤10 mm who were admitted to Guang'an Hospital,West China Hospital of Sichuan University,from January 2023 to June 2024 were enrolled and randomly divided into experimental group(without ureteral access sheath or ureteral stent)and control group(with ureteral access sheath and ureteral stent),with 35 patients in each group.The patients in the experimental group did not use a ureteral access sheath or a ureteral stent,while those in the control group used the ureteral access sheath and the ureteral stent.The two groups were compared in terms of preoperative data,intraoperative complications,stone clearance rate,length of hospital stay,hospital costs,and postoperative complications.Results:There were no sig-nificant differences between the two groups in preoperative data such as age,body mass index,sex,previous history of stone surgery,af-fected side,maximum stone diameter,C-reactive protein,aggregation system separation,preoperative CT value of stones,and stone lo-cation.The experimental group had a significantly shorter time of operation than the control group[(44.94±52.60)minutes vs.(52.60±14.22)minutes,t=2.240,P=0.030].There were no significant differences between the two groups in intraoperative data such as ureteral injury,intraoperative leukocyte changes,and intraopera-tive blood loss.The experimental group had significantly lower hos-pital costs than the control group[(8041.89±1287.57)yuan vs.(13 011.63±1 780.21)yuan,t=13.450,P=0.000].There were no significant differences between the experimental group and the con-trol group in the postoperative data such as the length of hospital stay,the recurrence of calculi on CT at 1 and 3 months after sur-gery,stone clearance rate,postoperative urinary tract irritation,post-operative ureteral injury,postoperative hematuria,and postoperative hydronephrosis(P>0.05).Conclusion:One-stage flexible uretero-scopic lithotripsy without ureteral access sheath or ureteral stent is safe and feasible in the treatment of upper ureteral calculi and renal calculi with a long diameter of≤10 mm and can effectively reduce hospital costs and time of operation.

Objective:To explore the expression of transmembrane protein 9(TMEM9)as an oncogene in prostate cancer(PCa),and to examine its effect on the proliferation and invasion of PCa cells as well as on the Wnt/β-catenin signaling pathway and autophagy of PCa cells by intervening with its expression.Methods:The Cancer Genome Atlas was used for pan-cancer analysis of TMEM9 expres-sion levels in different tumors,and TMEM9 protein and messenger ribonucleic acid(mRNA)levels in clinical PCa and prostatic hyper-plasia specimens were analyzed.Real-time quantitative polymerase chain reaction and western blotting were used to analyze TMEM9 expression levels in different PCa cell lines.Cell counting,terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL),and Transwell assay were used to analyze cell proliferation,apoptosis,and PCa cell invasion,respectively.Subcutaneous tu-morigenesis in nude mice was used to analyze tumor proliferation in vivo.Western blotting was used to analyze the expression of autophagy-related pathway proteins,and transmission electron microscopy and immunofluorescence colocalization were used to deter-mine the colocalization of autophagosomes and lysosomes.Results:TMEM9 was highly expressed in PCa.The mRNA and protein ex-pression levels of TMEM9 were higher in PCa tissues than in prostatic hyperplasia tissues.The expression of TMEM9 was highest in PC3 cells(human PCa cells)(t=17.150,P<0.01).In TMEM9-knocked down PC3 cells,the proliferation(t=3.165,P<0.05)and inva-sion(F=76.620,P<0.01)significantly decreased,and apoptosis(t=13.530,P=0.010)significantly increased.After knockdown of TMEM9,the volume(F=1 699.000,P<0.01)and weight(t=9.057,P<0.01)of subcutaneous tumors in nude mice were reduced,and tu-mor growth was inhibited.TMEM9 regulated the Wnt/β-catenin signaling pathway and inhibited the AKT-mTOR signaling pathway to promote autophagy in PCa cells.Conclusion:TMEM9 inhibits the AKT-mTOR signaling pathway and promotes the proliferation and invasion of PCa cells through autophagy.

BackgroundInsomnia， a common sleep disorder， is robustly associated with cardiovascular diseases， diabetes， and psychiatric disorders， substantially impairing quality of life. Although clinically commonly used medications are effective， long-term use may lead to drug resistance and dependence. While the efficacy of Ganmai Dazao Decoction in improving insomnia is definite， its underlying molecular mechanisms remain unclear. ObjectiveTo explore the active ingredients and core targets of Ganmai Dazao Decoction in the treatment of insomnia， systematically reveal its potential molecular pharmacological mechanism， and to provide references for clinical application. MethodsIn November 2024， the active ingredients and related targets of Ganmai Dazao Decoction were screened from the INPUT database. Insomnia-related datasets were acquired from the Gene Expression Omnibus （GEO） database， followed by differential expression analysis using GEO2R to identify differentially expressed genes （DEGs） associated with insomnia. The shared targets were obtained through Venn diagrams， and the protein-protein interaction （PPI） network was constructed using the STRING database and Cytoscape 3.9.1. Enrichment analyses were conducted on the shared targets using Gene Ontology （GO） and the Kyoto Encyclopedia of Genes and Genomes （KEGG）. The top 3 key active ingredients and the top 10 core targets in terms of node degree values were selected. Molecular docking and molecular dynamics simulation of receptors and ligands were performed using AutoDock 4.4.6， and the results were visualized using Pymol 3.0.3 to further verify the stability of the receptor-ligand complex system. ResultsA total of 337 active ingredients and 5 265 drug-related targets in Ganmai Dazao Decoction were retrieved， along with 1 061 insomnia-related DEGs. 287 shared targets were identified between Ganmai Dazao Decoction and insomnia. The traditional Chinese medicine-active ingredients-shared targets-disease network showed that quercetin， catechins and kaempferol were the key components of Ganmai Dazao Decoction in treating insomnia. These three components alleviate insomnia by acting on ten core targets， including nuclear factor kappa B inhibitor alpha （NFKBIA）， fibronectin 1 （FN1）， interleukin-6 （IL6）， protein c-Fos （FOS）， histone acetyltransferase p300 （EP300）， histone deacetylase 1 （HDAC1）， transcription factor Jun （JUN）， heat shock protein HSP 90-alpha 1 （HSP90AA1）， glyceraldehyde 3-phosphate dehydrogenase （GAPDH）， and interleukin-1 beta （IL1β）. GO and KEGG enrichment analyses indicated that Ganmai Dazao Decoction may alleviate insomnia through the IL17 signaling pathways， lipid and atherosclerosis signaling pathways， and other mechanisms. The results of molecular docking demonstrated strong binding affinity between the 3 key components and the 10 core targets of Ganmai Dazao Decoction. Molecular dynamics simulations further confirmed the stability of the quercetin-GAPDH， catechin-HDAC1 and kaempferol-EP300 complexes. ConclusionThe key components of Ganmai Dazao Decoction， namely quercetin， catechin， and kaempferol， exert therapeutic effects on insomnia by targeting 10 core proteins and modulating multiple pathways， including the IL17 signaling pathway， lipids and atherosclerotic-related pathways. ［Funded by Chengdu Medical College Level Scientific Research Project （number， CYZYB23-01）］

Neuropathic pain is a chronic pain condition caused by damage or dysfunction of the nervous sys-tem.Symptoms of neuropathic pain include spontaneous pain,hyperalgesia,and sensory abnormalities.AMP-activated protein kinase(AMPK)is a key energy regulator that maintains cellular homeostasis by modulating carbohydrate and lipid metabolism.Recent studies have highlighted its role in synaptic plasticity and glial cell function,suggesting that AMPK signaling pathways contribute to the onset and progression of neurological disorders.Investigations using animal models of neuropathic pain as well as clinical research have illustrated aberrations in AMPK expression and activity at various sites along sensory conduction pathways.Treatment with AMPK agonists has been shown to alleviate pain symptoms,suggesting that dysregulation of AMPK expression/function contributes to the development and persistence of neuropathic pain.There-fore,the development of analgesics targeting AMPK has garnered considerable attention worldwide.This article provides a comprehensive review of the mechanisms by which AMPK participates in neuropathic pain,with the aim of guiding the de-velopment of related analgesic drugs.

Objective: To investigate the influencing factors of depressive symptoms among rural elderly patients with chronic diseases in China, so as to provide insights into depression prevention and control among the rural elderly patients with chronic diseases. Methods: The basic demographics, health status, and lifestyle of rural residents at ages of 65 years and older who had at least one chronic disease were retrieved from The Chinese Longitudinal Healthy Longevity Survey (CLHLS) database in 2018, and participants' depressive symptoms were assessed with The Center for Epidemiological Studies Depression-10 (CES-D-10) scale. Factors affecting the depressive symptoms were identified with a multivariable logistic regression model. Results: Totally 5 146 rural elderly patients with chronic diseases were enrolled, including 2 373 men (46.11%) and 2 773 women (53.89%). The prevalence of depressive symptoms was 27.13%. Multivariable logistic regression analysis identified having two and more children (OR=0.614, 95%CI: 0.387-0.975), living alone (OR=1.450, 95%CI: 1.192-1.764), life satisfaction (general, OR=1.933, 95%CI: 1.651-2.264; low, OR=5.366, 95%CI: 3.488-8.254), self-assessed health status (general, OR=2.697, 95%CI: 2.284-3.185; poor, OR=5.338, 95%CI: 4.262-6.685), disability in instrumental activities of daily living (OR=1.592, 95%CI: 1.328-1.908), sleep duration (normal, OR=0.502, 95%CI: 0.429-0.586; too long, OR=0.494, 95%CI: 0.405-0.603), exercise (OR=0.721, 95%CI: 0.607-0.856), watching TV (OR=0.787, 95%CI: 0.664-0.933), and gardening activities (OR=0.781, 95%CI: 0.626-0.975) as factors affecting depressive symptoms among rural elderly patients with chronic diseases. Conclusions The prevalence of depressive symptoms was 27.13% among rural elderly patients with chronic diseases. Number of children, living style, life satisfaction, health status, sleep duration, exercise, watching TV, and gardening activities are associated with the development of depressive symptoms among rural elderly patients with chronic diseases.

ObjectiveTo determine whether HBV DNA polymerase is associated with T-cell failure and thus mediates the immune escape of HBV-related hepatocellular carcinoma （HCC） tumor cells， and to investigate the specific molecular mechanisms. MethodsLiver cancer cell lines Huh7 and HepG2 stably transfected with HBV DNA polymerase expression plasmid with Flag （Flag-HBV-P） and intercellular adhesion molecule-1 （ICAM1） were co-cultured with Jurkat cells， and MTT assay， qRT-PCR， and ELISA were used to measure Jurkat cell proliferation， activation （CD69 expression）， and secretion of the cytokine IFN-γ. RNA-seq was used to screen for differentially expressed immune-associated molecules between stably transfected cell lines and control cells， and mRNA half-life and protein half-life assays were used to determine the specific levels of the immune-associated molecules that were affected by HBV DNA polymerase. Related websites were used to predict the transcription factors that may bind to the promoter region of this immune-associated molecule， Western blot was used to verify the effect of transcription factors on the immune-associated molecule， and rescue experiment was used to determine whether HBV DNA polymerase affects the expression level of the immune-associated molecule through this transcription factor. The independent-samples t test was used for comparison between two groups. ResultsThe experimental group had significant reductions in Jurkat cell proliferation， activation， and cytokine secretion compared with the control group （all P<0.01）. Compared with the control group， the experimental group （Huh7 and HepG2 cell lines） had significant reductions in the mRNA and protein expression levels of ICAM1 （all P<0.01）. Website prediction identified the ICAM1 promoter and preliminarily highlighted NFKB1， RELA， and STAT3. Compared with the control group， the experimental group （Huh7 and HepG2 cell lines） had a significant reduction in the protein expression level of p65 （all P<0.01）. After p65 overexpression， there was a significant increase in the protein expression level of ICAM1， and after the expression of p65 was reduced， there was a significant reduction in the protein expression level of ICAM1 （all P<0.01）. In the rescue experiment， there was no significant difference in the protein expression level of ICAM1 between the control group and the experimental group after p65 overexpression （all P>0.05）. After the overexpression of ICAM1， there were no significant differences in the proliferation， activation， and cytokine secretion of Jurkat cells between the control group and the experimental group （Huh7 and HepG2 cell lines） （all P>0.05）. ConclusionHBV DNA polymerase downregulates the level of ICAM1 to mediate HCC immune escape by inhibiting the expression of p65 in NF-κB.

Objective:To evaluate the clinical efficacy of acupuncture combined with extracorporeal shock wave therapy in the treatment of piriformis syndrome.Methods:Eighty patients with piriformis syndrome who received treatment in Huaihe Energy Occupational Disease Prevention Hospital Rehabilitation Medicine Center from February 2021 to December 2022 were included in this study. They were divided into a treatment group ( n = 40) and a control group ( n = 40) according to different treatment methods using a retrospective cohort study design. The treatment group was treated with acupuncture combined with extracorporeal shock wave therapy, once every 7 days for 3 consecutive weeks. The control group was treated with extracorporeal shock wave therapy alone once every 7 days for 3 consecutive weeks.Pre- and post-treatment visual analogue scale scores and clinical efficacy were compared between the two groups. Results:There was no significant difference in baseline data between the two groups (all P > 0.05). After treatment, the visual analogue scale score decreased in each group. After adjusting for covariates, there was no significant difference in visual analogue scale score between the two groups ( F = 112.38, P < 0.001). After adjusting the pre-treatment visual analogue scale score, the post-treatment visual analogue scale score in the treatment group was lower than that in the control group [1.417 (95% CI: 1.151-1.683)]. The total response rate in the treatment group was 97.5% (39/40), which was significantly higher than 82.5% (33/40) in the control group ( Z = -2.03, P = 0.042). Conclusion:Acupuncture combined with extracorporeal shock wave therapy is highly effective on piriformis syndrome.

Objective:To investigate the application value of domestic robotic surgical system in radical resection of hilar cholangiocarcinoma (hCCA).Methods:The retrospective and descriptive study was constructed. The clinicopathological data of a 66-year-old male patient with hCCA who was admitted to the Second Hospital of Shandong University in November 2022 were collected. Radical resection of hCCA was performed using the Toumai? laparoscopic surgical robot system. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Count data were represented as absolute numbers and (or) percentages.Results:(1) Intraoperative conditions. The patient underwent radical resection of hCCA successfully using robotic surgical system, including tumor resection, lymph node dissection, and gastrointestinal reconstruc-tion. The operation time and volume of intraoperative blood loss were 400 minutes and 100 mL, respectively, and no intraoperative blood transfusion was required. (2) Postoperative conditions. The patient began ambulation on postoperative day 1 and began taking liquid food on postoperative day 4. Liver function examination and abdominal computed tomograph (CT) on postoperative day 5 showed a decrease in serum bilirubin, no biliary or intestinal leakage, and no edema or necrosis at the anastomotic site. The abdominal pre-anastomotic and post-anastomotic drainage tubes were removed on the 7th and 9th day after the surgery respectively, and the patient was discharged on the 10th day after surgery. Results of postoperative pathological examination showed moderately to poorly differentiated adenocarcinoma of the bile duct. Immunostaining was positive for CK7 and CK19. The Ki-67 proliferation index was 35%. The proximal and distal resection margin of bile duct were negative. The tumor diameter was 30 mm. Perineural invasion was positive. The surgical specimen margin was negative. Two lymph nodes were identified containing tumor cells positive for malignancy. No tumor cell metastasis was detected in the No.8, No.12 or gastric lesser curvature lymph nodes submitted for pathological examination. (3) Follow-up. The patient was followed up at postoperative 1-, 3-, 5-month after discharge. During follow-up period, results of liver function examination and abdominal CT showed liver function restore to normal levels, no complication such as biliary fistula, intestinal fistula, gastroparesis or tumor metastasis.Conclusion:The Domestic Toumai ? laparoscopic surgical robot system can be applied to radical resection of hCCA.

Despite the advancement of treatments, adults with relapsed/refractory (R/R) B-lineage acute lymphoblastic leukemia (B-ALL) have poor prognosis, with an expected five-year overall survival (OS) rate of 10%‒20% (Nguyen et al., 2008; Oriol et al., 2010). Extramedullary relapse of B-ALL is regarded as a high-risk factor generally associated with poor survival, occurring in about 15% to 20% of all relapsed patients (Ding et al., 2017; Sun et al., 2018). The central nervous system (CNS) and the testes are the most common sites of extramedullary relapse of B-ALL. In addition, extramedullary leukemia can appear in the skin, eyes, breasts, bones, muscles, and abdominal organs. The prognosis of relapsed extramedullary B-ALL after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is extremely poor (Spyridonidis et al., 2012; Dahlberg et al., 2019). Conventional chemotherapy or radiation is often ineffective in such patients. At present, there are no optimal treatment strategies for treating extramedullary leukemia after allo-HSCT.

Objective:To compare the differences of short and long-term outcomes between laparoscopic surgery and open surgery treatment of intrahepatic cholangiocarcinoma patients.Methods:A retrospective cohort study was conducted to collect the clinical data of 118 patients with intrahepatic cholangiocarcinoma who underwent surgery in Qilu Hospital of Shandong University from January 2015 to June 2020. They were divided into laparoscopy group and open group according to the operation methods. The perioperative data, such as intraoperative surgical conditions, hospital costs, postoperative complications, postoperative blood biochemical tests, and the follow-up data of the two groups were compared.Results:In the laparoscopic group, there were 40 patients, 18 males and 22 females, aged (61.5±9.1) years. There were 78 patients in the open group, 48 males and 30 females, aged (61.2±8.3) years. The tumor size of the laparoscopic group was (4.4±1.8) cm, which was smaller than that of the open group (6.0±3.3) cm, and the differences were statistically significant ( P<0.05). In the laparoscopic group, 4 cases (10%) were converted to open surgery. The intraoperative blood loss, intraoperative blood transfusion proportion, 3 or more liver segments resection proportion and hospital costs of laparoscopic group were lower than those of open group [200.0(100.0, 261.8) ml vs. 300.0(100.0, 400.0) ml, 5.0%(2/40) vs. 26.9%(21/78), 37.5%(15/40) vs. 66.7%(52/78), (6.2±2.0) wan yuan vs. (7.2±2.3) wan yuan], the differences were statistically significant (all P<0.05). There were no significant differences in the incidence of postoperative complications between the two groups ( P>0.05). On the first post-operative day, ALT serum level and the third post-operative day TBil serum level in the laparoscopic group were lower than those in the open group [188.5(130.5, 274.0) U/L vs. 320.0(144.0, 427.0) U/L, 26.4(18.3, 26.4) μmol/L vs. 31.6(18.8, 37.5) μmol/l], the differences were statistically significant ( P<0.05). There were no significant differences in 1-year and 2-year overall survival rate and disease-free survival rate between the two groups ( P>0.05). Conclusion:Compared with open surgery, laparoscopic surgery in the treatment of intrahepatic cholangiocarcinoma has better short-term outcomes, and can achieve similar results in medium- or long-term outcomes.
