Long term follow up outcome of artificial urinary sphincter implantation to treat stress urinary incontinence / 中华泌尿外科杂志

Objective:To investigate the long term outcome of artificial urinary sphincter implantation for patients with stress urinary incontinence.Methods:The data of 46 patients who underwent artificial urethral sphincter implantation in China Rehabilitation Research Center from April 2002 to April 2022 were retrospectively analyzed.The patients’ age ranged from 19-80 years old (median 45.6 years). There were 45 males and 1 female. The history of illness was 8 months to 33 years. The patients category were urethral injuries associated urinary incontinence ( n=24), neurogenic urinary incontinence ( n=9) and post-prostatectomy incontinence ( n=13). Preoperative daily pad usage was 3.5±1.0. The impact of incontinence on the quality of life (QOL)measured by the visual analogue scale (VAS)was 7.1±1.2. All 46 patients underwent artificial urethral sphincter implantation, of which 20 patients were treated with anticholinergic drugs (5 cases) or urinary tract related surgery (urethral stenosis incision in 2 cases, sphincterectomy in 3 cases, urethral dilation in 5 cases, urethral calculus lithotripsy in 1 case, and augmentation cystoplasty in 4 cases) before artificial urethral sphincter implantation. Of the 45 male patients, 25 patients had the transperineal approach and 20 had the trans-scrotal approach. The female case had a trans-retropubic approach. Different cuffs size was used based on individual circumference of bulbar urethra (45 male cases: 4.5cm in 16 cases, 4.0cm in 29 cases; one female case: 8.0cm). Long-term surgical efficacy was evaluated. Assessments included postoperative urinary continence (socially continent: one pad per day or less; complete dry: wearing no pads), artificial urinary sphincter status and complications. The influences of patients of different etiologies, surgical approaches and cuff size on surgical results were compared. Results:The mean follow-up time was 7.1 years ranged from 6 months to 19 years. At the latest visit, 32 patients (69.6%) maintained the primary functional artificial urinary sphincter. Three patients (6.5%) had artificial urinary sphincter revisions and maintained continence with the new device. 11 patients (23.9%) removed the artificial urinary sphincter because of post-complications. Thirty-five patients were socially continent, of which 16 patients were totally dry, leading to the overall social continent rate as 76.1%(35/46). There was a significant reduction in pad usage to 1.2±0.6 diapers per day ( P<0.001). The impact of incontinence on the QOL measured by the VAS dropped to 2.6±1.9 ( P<0.001). The complication rate was 32.6%(15/46), including infections ( n=4), erosions ( n=5), mechanical failure ( n=3), dysurie ( n=2) and urethral atrophy ( n=1). There were no significant differences in social continent rate between patients with different etiologies[75.0%(18/24)vs. 66.7%(6/9) vs. 84.6%(11/13)], perioperative complications [37.5%(9/24)vs. 33.3%(3/9) vs. 23.1%(3/13)] and device re-intervention rate[37.5%(9/24) vs. 33.3%(3/9)vs. 15.4%(2/13)]. There were no statistically significant differences in postoperative complete dry rate [32%(8/25)vs. 40%(8/20), P=0.76] and postoperative device failure free rate [60%(15/25)vs. 80%(16/20), P=0.20] between trans-perineal group and trans-scrotal group. There was no statistically significant difference in postoperative social continent rate between 4.5cm cuff and 4.0 cuff[75%(12/16) vs. 65.5%(19/29), P=0.74]. Conclusions:Artificial urethral sphincter implantation is an effective treatment for stress urinary incontinence due to intrinsic sphincter deficiency. There was no difference in the continent rate and complication rate between patients of different etiologies, different surgical approaches and cuff size selection.

Augmentation uretero-enterocystoplasty for lower urinary tract dysfunction: a long-term retrospective efficacy study / 中华泌尿外科杂志

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

Effects of Acute Sacral Neuromodulation at Different Pulse Widths on Bladder Overactivity in Pigs / 대한배뇨장애요실금학회지

PURPOSE: Sacral nerve stimulation has been used to treat overactive bladder. This study evaluated the effects of stimulation using different pulse widths on the inhibition of bladder overactivity by sacral nerve stimulation (SNM) in pigs. METHODS: Implant-driven stimulators were used to stimulate the S3 spinal nerve in 7 pigs. Cystometry was performed by infusing normal saline (NS) or acetic acid (AA). SNM at pulse widths of 64 μsec to 624 μsec was conducted at the intensity threshold at which observable perianal and/or tail movement was induced. Multiple cystometrograms were performed to determine the effects of different pulse widths on the micturition reflex. RESULTS: AA-induced bladder overactivity reduced the bladder capacity to 46.9%±7.1% of the NS control level (P0.05). The actual intensity threshold varied from 0.7 to 8 V. The mean intensity threshold (T visual) for pulse widths of 64 μs, 204 μs, and 624 μs were 5.64±0.76 V, 3.11±0.48 V, and 2.52±0.49 V. T visual for pulse widths of 64 μsec was larger than the other two T visual for pulse widths of 204 μsec and 624 μsec (P0.05). CONCLUSIONS: This study indicated that different pulse widths could play a role in inhibiting bladder overactivity. It is not yet certain which pulse widths increased bladder capacity compared with AA levels, to minimize energy consumption and maintain patient comfort during stimulation, 204 μsec may be an appropriate pulse width for SNM.

Synthesis and Evaluation of a Novel Small-molecule Compound as an Anticancer Inhibitor of CD147 / 生物医学与环境科学（英文）

OBJECTIVE@#Cancer is a serious threat to human health. Despite extensive research on cancer treatment, there is a growing demand for new therapies. CD147 is widely involved in tumor development, but it is unclear whether cancer cell malignancy is affected by CD147 expression level. The first compound (AC-73) targeting CD147 could only act on advanced tumors and inhibit metastasis. Therefore, new compounds with better anticancer activity should be explored.@*METHODS@#Wst-1 assays were used to confirm the effect of novel compounds on proliferation. Apoptosis tests were used to evaluate their proapoptotic capacity. A nude mouse model was used to demonstrate in vivo anticancer activity and safety of the compounds. Western blots were used to suggest a molecule mechanism.@*RESULTS@#There is a positive correlation between CD147 expression and tumor cell proliferation. A new compound, HA-08, was synthesized and proved to be more active than AC-73. HA-08 could inhibit cancer cell viability and promote cancer cell apoptosis both in vitro and in vivo. HA-08 induces cancer apoptosis, mainly by disrupting the CD147-CD44 interaction and then down-regulating the JAK/STAT3/Bcl-2 signaling pathway.@*CONCLUSION@#Our results have clarified the tumor specificity of CD147 and its drug target characteristics. The biological profile of HA-08 suggests that this compound could be developed as a potential anticancer agent.

UPLC/ESI-QTOF-MS-based metabolomics survey on the toxicity of triptolide and detoxication of licorice / 中国天然药物

Triptolide (TP) from Tripterygium wilfordii has been demonstrated to possess anti-inflammatory, immunosuppressive, and anticancer activities. TP is specially used for the treatment of awkward rheumatoid arthritis, but its clinical application is confined by intense side effects. It is reported that licorice can obviously reduce the toxicity of TP, but the detailed mechanisms involved have not been comprehensively investigated. The current study aimed to explore metabolomics characteristics of the toxic reaction induced by TP and the intervention effect of licorice water extraction (LWE) against such toxicity. Obtained urine samples from control, TP and TP + LWE treated rats were analyzed by UPLC/ESI-QTOF-MS. The metabolic profiles of the control and the TP group were well differentiated by the principal component analysis and orthogonal partial least squares-discriminant analysis. The toxicity of TP was demonstrated to be evolving along with the exposure time of TP. Eight potential biomarkers related to TP toxicity were successfully identified in urine samples. Furthermore, LWE treatment could attenuate the change in six of the eight identified biomarkers. Functional pathway analysis revealed that the alterations in these metabolites were associated with tryptophan, pantothenic acid, and porphyrin metabolism. Therefore, it was concluded that LWE demonstrated interventional effects on TP toxicity through regulation of tryptophan, pantothenic acid, and porphyrin metabolism pathways, which provided novel insights into the possible mechanisms of TP toxicity as well as the potential therapeutic effects of LWE against such toxicity.

<p><b>OBJECTIVE</b>To study the risk factors for the development of acute respiratory distress syndrome (ARDS) in children with measles.</p><p><b>METHODS</b>The clinical data of 55 children with measles were retrospectively studied. Of the 55 children, 11 were complicated by ARDS. The risk factors for the development of ARDS were investigated by univariate analysis and multivariate non-conditional logistic regression analysis.</p><p><b>RESULTS</b>The univariate analysis showed that there were significant differences in the oxygen inhalation mode (nasal catheter/mask), the rate of sepsis, blood C-reactive protein (CRP) levels and lymphocyte counts at admission between the ARDS and non-ARDS groups (P<0.05). The presence of sepsis and higher blood CRP levels were identified as the major risk factors for the development of ARDS by the multivariate logistic regression analysis (OR=116.444, 1.050 respectively; P<0.05).</p><p><b>CONCLUSIONS</b>The children with measles who have sepsis and higher blood CRP levels are at risk of ARDS.</p>

Effects of Qingretonglin Pill on Urinary Tract Infections after Spinal Cord Injury / 中国康复理论与实践

@#Objective To explore the effect of Qingretonglin pill combined with levofloxacin tablet on urinary tract infection after spinal cord injury. Methods 55 spinal cord injury patients with urinary tract infection were divided into control group (n=27) and observation group (n=28). Levofloxacin tablets were orally administered in both groups, 500 mg everyday, 14 days. The Qingretonglin pill was also orally administered in the observation group, 1.6 g, 3 times every day, 14 days. The improvement time of frequent micturition, urgent urination and odynuria, and urinary leukocyte number, urinary bacterial quantitative culture changes and the side effect before and after treatment were observed. Results The effective rate was higher in the observation group (89.3%) than in the control group (63%) (P<0.05). The improvement time of frequent micturition, urgent urination and odynuria was shorter in the observation group than in the control group (P< 0.05). The number of urinary leukocyte and urinary bacterial significantly decreased after treatment (P<0.001), and was less in the observation group than in the control group (P<0.05). The rate of side effect was low in both groups, and there was no significant difference (P> 0.05). Conclusion Qingretonglin pill can release the clinical symptoms of urinary tract infection after spinal cord injury, and improve the clearance rate of bacteria.

Early multi-disciplinary intervention reduces neurological disability in premature infants / 中国当代儿科杂志

<p><b>OBJECTIVE</b>This study aimed to evaluate the effectiveness of multi-disciplinary treatment approaches in reducing neurological disabilities in premature infants.</p><p><b>METHODS</b>A total of 117 infants who were born premature in our hospital between March 2008 and February 2010 but had no congenital malformations and no severe neonatal complications, were enrolled in this study. They were randomly allocated to a multi-disciplinary treatment group (n=63) and a control group (n=54). While patients in the control group underwent an early conventional treatment, those in the multi-disciplinary treatment group were subjected to regular development monitoring, neurological examination and screening for brain injury, neuro-nutrition and neurodevelopment therapies, and rehabilitation training.</p><p><b>RESULTS</b>The incidence rates of abnormalities in posture, reflex, sleep, muscle tone and EEG were significantly lower in the multi-disciplinary treatment group than in the control froup (P<0.05) at corrected postnatal ages of 6-12 months. At corrected postnatal ages of 6, 12, 18 and 24 months, both mental development index (MDI) and psychomotor development index (PDI) scores were significantly higher in the multi-disciplinary treatment group than in the control group (P<0.05). At corrected postnatal age of 3 years, incidence rates of cerebral palsy, language barrier, abnormal muscle tone and hearing impairment were significantly lower in the multi-disciplinary treatment group than in the control group (P<0.05).</p><p><b>CONCLUSIONS</b>Early multi-disciplinary intervention approaches may significantly improve mental and motor developments and reduce the incidence of cerebral palsy-associated neurological disabilities in premature infants.</p>
