Objective To investigate the impacts of intervertebral foramen endoscopic surgery combined with silver needle hyperthermia therapy on lumbar spine function and local tenderness in patients with lumbar disc herniation(LDH).Methods From April 2020 to March 2023,100 LDH patients were randomly devided into a control group(50 cases)and an observation group(50 cases)through random number table method.The control group was treated with intervertebral foramen endoscopic surgery combined with conventional lumbar and dorsal muscle training,while observed group was treated with intervertebral foramen endoscopic surgery combined with silver needle warm therapy.The lumbar function,local tenderness,laboratory indicators,and adverse reactions were compared.Results The Japanese Orthopaedic Association(JOA)score increased in both groups after treatment,and observed group had obviously higher scores,the differences were statistically significant(P<0.05);After treatment,both groups showed a decrease in pain visual analogue scale(VAS)score,and observed group had obviously lower scores,the differences were statistically significant(P<0.05);The levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),prostaglandin E2(PGE2),and 5-hydroxytryptamine(5-HT)in both groups decreased after treatment,and the observed group showed a more obvious decrease in all indicators,the differences were statistically significant(P<0.05);The incidence of adverse reactions was 4.00%(2/50)in observed group and 20.00%(10/50)in the control group,adverse reactions in observed group were obviously fewer,the difference was statistically significant(P<0.05).Conclusion The combination of intervertebral foramen endoscopic surgery and silver needle hyperthermia therapy can effectively improve lumbar spine function and alleviate local tenderness symptoms in patients with LDH.It is worthy clinical application.

Objective:To investigate the mechanism by which formononetin combined with platelet-rich plasma (PRP) enhances the proliferation and differentiation of osteoblasts.Methods:Rat osteoblasts ROS17/2.8 were cultured in vitro and treated with formononetin (10, 20, 40 μmol/L) combined with PRP. Cells were also intervened with G15 (a G protein-coupled estrogen receptor inhibitor) and Super-TDU [a Yes-related protein (YAP) inhibitor]. Cell proliferation viability was detected using the cell counting kit-8 (CCK-8) assay; alkaline phosphatase (ALP) activity was measured using an ALP assay kit; protein expression of G protein-coupled estrogen receptor (GPER) and p-YAP was detected by Western blot; and YAP subcellular distribution was analyzed by fluorescence assay.Results:Formononetin (20 μmol/L) synergistically enhanced the PRP-induced proliferation and ALP activity of osteoblasts (all P<0.05). Compared with the control group, formononetin significantly up-regulated GPER protein expression and down-regulated p-YAP protein expression (all P<0.01), with the most pronounced effects observed at 20 μmol/L. Formononetin (20 μmol/L) induced nuclear accumulation of YAP protein in osteoblasts. Pretreatment with G15 or Super-TDU reversed the synergistic effect of formononetin on PRP, and both the cell proliferation rate and ALP activity were lower than those in the PRP+ formononetin group (all P<0.01). Conclusions:Formononetin enhances the PRP-induced proliferation and differentiation of osteoblasts through the GPER/YAP signaling pathway.

Objective To characterize working memory performance in patients with chronic fatigue syndrome(CFS)and spleen-deficiency syndrome and to examine its associations with clinical symptoms by Sternberg working memory task(SWMT).Methods 31 CFS patients meeting both CDC-1994 criteria and consensus criteria for spleen-deficiency pattern were recruited from outpatient clinics and universities from September 2022 and June 2025.31 healthy controls were also recruited based on age,sex,and education.All subjects completed the SWMT.Group differences were analyzed.Within the CFS cohort,reaction time(RT)was correlated with scores on the checklist individual strength(CIS),36-item short-form health survey(sf-36),and fatigue scale-14(FS-14).Mediation was examined.Results RT lengthened with increasing memory load in both groups.CFS patients displayed slower RTs than controls in the baseline and 6-digit set(P<0.05).The 3-digit RT difference,though not significant(P>0.05),yielded a medium effect size(r=0.36).Accuracy did not differ between two groups.Among CFS patients,3-digit RT correlated positively with CIS total and the 4 sub-scale scores.6-digit RT correlated with the SF-36 health-transition dimension(r=0.396,P=0.027).CIS and FS-14 scores directly impaired SF-36 social functioning without working-memory mediating.Conclusion CFS patients with spleen-deficiency exhibit slowed processing speed rather than capacity loss.The close link between working-memory slowing and fatigue suggests a distinct neural basis.These results support the traditional concept"the spleen stores Yi"and integrate TCM pattern differentiation with modern cognitive neuroscience in CFS.

Objective:To evaluate the clinical value of nanopore targeted sequencing (NTS) in pathogens detection in urinary tract by comparing the results of different tests performed on the same urine sample.Methods:The results of NTS and urine culture test collected from 326 patients in the Department of Urology of People's Hospital of Wuhan University from July 2020 to June 2021 were retrospectively analyzed. There were 224 males and 102 females. The average age was (56.88 ± 14.58)years old. χ 2 test and Student’s test and Wilcoxon's sign rank test were used to analyze the differences of the pathogen detection rate, pathogen types results and detection time consuming between NTS and urine culture. The clinical value of the NTS in rapid detection of urinary pathogens was evaluated. Results:Among 326 hospitalized patients, the urinary tract microbes’ detecting rate of NTS was significantly higher than that of urine culture[67.80%(221/326)vs. 23.93%(78/326), χ2=130.25, P<0.01]. The uropathogens detecting rate of NTS was significantly higher than that of urine culture[54.29%(177/326)vs. 23.31%(76/326), χ2=38.95, P<0.01]. The number of urinary tract microbes detected by NTS was significantly higher than that of urine culture ( Z=11.49, P<0.01), the number of uropathogens was significantly higher than that of urine culture ( Z=9.67, P<0.01). The detection time of NTS and urine culture positive samples was (24.29±2.65) h and (49.28±11.30) h, the difference was statistically significant ( t =39.48, P<0.01). The results obtained by using NTS and urine culture were consistent in 135 (41.41%) samples. In 150 (46.01%) samples, NTS could detect the urinary tract microbes while urine culture cannot find, of which 112 cases (34.36%) were uropathogenic. In 27 cases (8.28%), more pathogens were detected by NTS except those from urine culture. In 6 cases (1.84%) re-detecting NTS after antibiotic therapy, the number of reads of primary uropathogen decreased gradually with the growth of colonizing bacteria or opportunistic pathogens appeared in the end. Re-examinations of urine culture could verify the results of NTS detection on admission in 5 cases (1.53%). NTS in 2 cases (0.61%) could cover the uropathogens of subsequent several urine cultures. Conclusions:NTS has the advantages of rapid, sensitive and comprehensive detection of urinary tract infection pathogens. When urine culture is not yet reported or even negative, NTS already has a certain clinical reference value and can be used as an effective supplement to urine culture, which is conducive to the comprehensive judgment of the patient's condition.

Objective:To explore the efficacy and safety of robot assisted laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse.Methods:The data of 16 patients who underwent robot assisted laparoscopic sacrocolpopexy in Beijing Hospital from September 2019 to May 2022 were collected. The average age was (73.5±9.3) years, the preoperative course was 4-240 months, the body mass index was (24.2±1.7) kg/m 2, the number of births was (1.7±0.8), and the quantitative index of pelvic organ prolapse (POP-Q) was grade Ⅲ -Ⅳ. The maximum urine flow rate before operation was (9.6±3.4) ml/s, the maximum detrusor pressure during urination was 26 (20, 32) cmH 2O, the first sense urine volume of the bladder was (119.1±39.4) ml, the first sense urine urgency volume of the bladder was (253.6±75.7) ml, the maximum bladder pressure capacity was (406.0±79.8) ml, and the residual urine volume was 10 (10, 28) ml. The preoperative PFDI-20 score was 100 (70, 122) and the PFIQ-7 score was 107 (90, 160). During the robot assisted laparoscopic sacrocolpopexy, the right area of the sacral promontory was exposed, the anterior and posterior walls of the uterus were separated, and the 2 cm small hole was separated from the right broad ligament of the uterus. The mesh was cut into a "Y" shape and passed through the small hole. The anterior and posterior leaves of the Y-shaped mesh were sutured to fix the cervix, and the other end was fixed to the anterior longitudinal ligament of the sacrum. The operation time and intraoperative bleeding were observed. The effect of surgery was evaluated by preoperative and postoperative urodynamic imaging, POP-Q stage, PFDI-20 score and PFIQ -7 score. Results:All the 16 operations were successfully completed. No injury of urethra, bladder, rectum, important blood vessels and nerves occurred during the operation. The average operation time was (255.6±56.0) min, and the average amount of bleeding was (28.8±18.2) ml. There was no inhibitory contraction wave in 7 patients (44%) before operation, suggesting that there was detrusor overactivity. After operation, the detrusor overactivity disappeared or significantly decreased in 7 patients. The postoperative follow-up period was 3-36 months. During the follow-up period, one patient had recurrence, and the rest had no prolapse and urination problems. The POP-Q stage was reduced to grade 0-Ⅰ after the operation. The subjective satisfaction rate of patients was 94%. The PFDI-20 score [13(8, 24)] and PFIQ -7 score [11(6, 15)] after operation were significantly reduced ( P<0.001), the initial urgent volume of bladder (272.5±88.5) ml was significantly increased compared with that before operation ( P=0.038), and the maximum volume of bladder (427.2±79.2) ml was significantly increased compared with that before operation ( P=0.006). Image urodynamics showed that the patient basically recovered the pelvic floor anatomy and achieved functional reduction. Conclusions:Robot assisted laparoscopic sacrocolpopexy has good subjective and objective effects in POP, low recurrence rate and less complications. It needs a larger sample size study for confirming the improvement of bladder function.

Objective:To investigate the availability and safety of a domestic disposable digital flexible cystoscope compared with a reusable Olympus digital flexible cystoscope in cystoscopy and removal of double J stent.Methods:From August 2018 to March 2019, patients were enrolled in this prospective, open, multicenter, randomized, parallel positive controlled clinical trial study, which were from department of Urology in Renmin Hospital of Wuhan University, the First Affiliated Hospital of Xiamen University and the First Affiliated Hospital of Guangzhou Medical University. The experimental group and control group were assigned into a 1∶1 ratio by random table method. Inclusion criteria included age≥18 years and have indications for cystoscopy or removal of double J stent. Exclusion criteria included patients having acute genitourinary tract infection, having tuberculous bladder contracture, bladder capacity less than 50ml, having urethrostenosis, female menstrual period, pregnancy and lactation, having difficulty for lithotomy position, having serious cardio-cerebrovascular disease and liver or kidney dysfunction. A domestic disposable digital flexible cystoscope was adopted in the experimental group, whereas a reusable Olympus digital flexible cystoscope was used in the control group. Acceptability of image was defined as primary availability indicator, while success rate of working and performance score were defined as secondary availability indicators and mean operating time was calculated for cystoscopy only and cystoscopy plus removal of double J stent respectively, yet rate of adverse event as well as rate of equipment defects were sorted as safety indicators.Results:A total of 188 cases which were listed in per protocol set completed the clinical trial study successfully. There were 95 cases in the experimental group and 93 cases in the control group. Acceptability of image was 93.68%(89/95) and 96.77%(90/93) respectively in two groups( P=0.52). Success rate of working was 100.00%(95/95) and 98.92%(92/93) respectively in two groups ( P=0.49). Performance score was 14.41±0.93 and 14.56±0.84 respectively in two groups ( P=0.23). Mean operating time (MOT) only for cystoscopy was (15.3±2.6) min and (15.4±3.3)min respectively in two groups ( P=0.93), while MOT for cystoscopy plus removal of double J stent was (21.0±3.2) min and (21.7±3.9) min respectively in two groups ( P=0.69). Rate of adverse event was 8.42%(8/95) and 9.68%(9/93) respectively in two groups( P=0.76). There was no equipment defects in both groups. Conclusions:There is no statistical difference in acceptability of image, success rate of working, performance score, mean operating time for cystoscopy or removal of double J stent, rate of adverse events and rate of equipment defects. A domestic disposable digital flexible cystoscope has shown non-inferiority in the availability and safety compared with a reusable Olympus digital flexible cystoscope.

Objective:To explore the potential relationship of urethral pressure profilometry and the complications of artificial urethral sphincter (AUS) implantation.Methods:The clinical data of patients who underwent AUS implantation in Beijing Hospital from March 2019 to March 2022 were retrospectively analyzed. All the patients were male. The average course of disease was 43.1 months(ranging 11-120 months). The average age was (68.6±13.2) years. The median number of pads used was 4.5 (3.0, 6.0). The preoperative maximum urethral pressure (MUP) was (84.6±25.5) cmH 2O, and the maximum urethral closure pressure (MUCP) was 51.0 (41.0, 74.0) cmH 2O. AUS implantation was performed through a single perineal incision in all patients. The sleeve size was mainly determined by the measured urethral circumference of the patient. After installation of all components, the urethral pressure profilometry was performed under the state of device inactivation and activation. The pump was activated 6 weeks after the operation, and telephone follow-up was performed 3 months after the activation of the device. The urinary control and complications were recorded. The results of follow-up were compared with the results of urethral pressure profilometry, and the preliminary conclusions were drawn. Results:In this study, 3 patients (20%) received 4.0cm cuffs, 10 patients (66.7%) received 4.5cm cuffs, and 2 patients (13.3%) received 5.0cm cuffs. The MUP and MUCP of AUS device in inactivated state were (82.5±30.2) cmH 2O and 51.0(48.0, 77.0) cmH 2O. In the activated state, MUP was (138.9±21.7) cmH 2O and MUCP was 109.0(94.0, 133.0) cmH 2O. Compared with that before operation, the urethral pressure in the inactivated state did not increase significantly (all P > 0.05), while the urethral pressure in the activated state increased significantly (all P < 0.001). The patients were followed-up for 3-33 months. Thirteen patients (86.7%) used the initial installation device, and all of them met the standard of social continence. One patient died of cerebrovascular accident. One patient took out the device due to urethral erosion. The incidence of complications was 26.7% (4/15), including painless hematuria in 2 cases, scrotum and penis infection in 1 case, and urethral erosion in 1 case. The MUP and MUCP of these patients were (100.0 ± 40.7) cmH 2O and (80.8 ± 39.7) cmH 2O respectively. In the intraoperative active state, the MUP was (151.5 ± 15.3) cmH 2O and the MUCP was (123.0 ± 17.2) cmH 2O. The MUP of the other 3 patients in the device activation state was significantly higher than the average value, and all of them were above 150 cm H 2O, except one patient who was infected due to cognitive problems and chronic urinary retention. In 11 patients without complications, the MUP and MUCP were (76.1±24.7) cmH 2O and (55.1±20.0) cmH 2O respectively. In the intraoperative active state, the MUP was (134.4±22.5) cmH 2O and the MUCP was (108.5±29.8) cmH 2O. Conclusions:AUS implantation has a definite curative effect. Poor comprehension, and MUP higher than 150 cmH 2O in the activated state of the device may be risk factors for complications.
