Objective:To investigate the treatment strategies for vesicovaginal fistula(VVF)in women following cervical cancer radiotherapy.Methods:A retrospective analysis was performed on the clinical data of 33 female patients with post-radiotherapy VVF after cervical cancer treatment at Shanghai Sixth People’s Hospital between January 2020 and June 2024. The patients were categorized into three groups based on surgical approaches:Group A(11 patients):Underwent prone-position VVF repair. Mean age:(50.0±9.6)years;mean radiotherapy sessions:(22.6±2.2). All had simple VVF without concurrent intestinal or surrounding soft-tissue fistulas. Among them,1 patient previously received laparoscopic VVF repair,1 transvaginal VVF repair,and 2 gracilis muscle flap packing for VVF repair. One month prior to surgery,the average daily usage of urine pads was 16.7(12.8,25.7)pieces,and the quality of life(QOL)score stood at 4.0(4.0,5.0)points. Preoperative cystoscopy revealed that 8 cases had fistulas located in the trigonal region of the bladder,while 3 cases had fistulas on the posterior bladder wall. The diameter of the fistula openings,measured under a microscope,was 1.2(0.8,1.6)cm. Based on the Goh classification criteria for vesicovaginal fistulas,this group included 3 cases of type 1,4 cases of type 2,2 cases of type 3,and 2 cases of type 4;7 cases of type A and 4 cases of type B;as well as 3 cases of typeⅠ,7 cases of type Ⅱ,and 1 case of type Ⅲ.Group B(20 patients):Underwent gracilis muscle flap packing for VVF repair. Mean age:(58.6±8.8)years;mean radiotherapy sessions:(29.8±3.9). Three patients had concurrent rectovaginal fistulas and received colostomy for fecal diversion. History of previous interventions:3 had laparoscopic VVF repair,4 transvaginal VVF repair,and 1 both transvaginal and laparoscopic VVF repair. One month prior to surgery,the average daily usage of urine pads was 19.7(15.8,27.7)pieces,and the QOL score stood at 5.0(5.0,6.0)points. Preoperative cystoscopy revealed that 13 cases had fistulas located in the trigonal region of the bladder,while 7 cases had fistulas on the posterior bladder wall. The diameter of the fistula openings,measured under a microscope,was 1.8(1.0,3.2)cm. Based on the Goh classification criteria for vesicovaginal fistulas,this group included 4 cases of type 1,9 cases of type 2,3 cases of type 3,and 4 cases of type 4;6 cases of type A,11 cases of type B and 3 cases of type C;as well as 1 cases of type Ⅱ,and 19 case of type Ⅲ. Group C(2 patients):Underwent ureterocutaneous diversion. Ages:67 and 73 years;radiotherapy sessions:51 and 60,respectively. Both had concurrent rectovaginal fistulas and bladder soft-tissue fistulas. The patient presented with recurrent thigh abscesses accompanied by fever. One month prior to surgery,the daily usage of urine pads was 29 and 23 pieces,respectively,and the QOL score was 6 points. Cystoscopic examination revealed that the vesicovaginal fistulas were located in the trigone of the bladder,with diameters of 3 cm and 4 cm,respectively. Additionally,partial defects were noted in the ventral wall of the urethra,while no bladder soft tissue fistulas were detected. According to the Goh classification for vesicovaginal fistulas,both cases were categorized as type 4,type C,and type Ⅲ. For Groups A and B,urinary catheters were indwelled for 3 weeks postoperatively,then removed to assess spontaneous urination and incontinence. QOL was evaluated,with a minimum 6-month follow-up. For confirmed postoperative VVF recurrence,re-repair was performed 3?6 months later based on patient preference. For Group C,double-J stents were placed in the ureters,and stoma bags were applied 3 days postoperatively. Stents were replaced every 1?2 months,with QOL assessment. Successful fistula repair in Groups A and B was defined as the absence of vaginal leakage confirmed by cystoscopy after six months of the procedure with no vaginal leakage. For Group C,surgical success was determined by the resolution of perineal urinary leakage and improvement in QOL.Results:All 33 patients completed surgery successfully. Group A:Follow-up duration:16.3(9.6,24.6)months. Surgical repair succeeded in 7 patients,with unobstructed spontaneous urination and no vaginal incontinence. Four patients had VVF recurrence:2 refused further treatment,and 2 underwent repeat gracilis muscle flap packing. One was successfully repaired,while one recurrence case refused further treatment. Group B:Follow-up duration:17.0(9.5,24.8)months(8?32 months). Thirteen patients restored spontaneous urination without recurrence. Seven had recurrence:5 refused further surgery,and 2 underwent re-repair. One repair succeeded without incontinence,while one recurrence case refused treatment. Group C:Follow-up durations were 6 and 22 months. Perineum remained dry without incontinence(no urine pads needed),and no recurrence of thigh soft-tissue redness/infection occurred. QOL scores were 2 and 3,respectively.Conclusions:Post-radiotherapy VVF in women after cervical cancer presents complex and variable conditions. The primary goal of treatment should be to improve patients’ quality of life. Treatment approaches should be selected based on the complexity of urinary fistulas and local tissue conditions. In general,patients who are younger,have received lower doses of radiation therapy,present with smaller fistula diameters,have well-vascularized and elastic perifistular tissues,and have no concurrent tissue fistulas are candidates for prone-position VVF repair. Patients who do not meet the criteria for transvaginal repair,have a history of at least two previous repair attempts,or have concurrent vaginorectal fistulas require gracilis muscle flap packing for VVF repair. Patients with three or more types of concurrent tissue fistulas,extensive pale and inelastic perifistular tissues,and who are not amenable to repair surgery undergo ureterocutaneous diversion.

Objective:To explore the application value of transpubic access on female urogenital tract injury.Methods:A retrospective analysis was conducted on 15 female patients with urogenital tract injury caused by trauma admitted to our department from May 2020 to October 2024,all of whom were complicated urethral stricture or atresia,accompanied by urethrovaginal fistula or vaginorectal fistula. All patients underwent suprapubic vesicostomy before surgery,and 1 case underwent sigmoidostomy simultaneously. The mean age of the patients was(29.6 ± 3.2)years old,and the course of disease was 6-24 months. Preoperative urethrography and urethroscope showed the location of urethral stenosis,with proximal urethra stricture in 7 cases and distal urethra stricture in 8 cases. The average length of strictures was(2.8±0.2)cm. The urethral ultrasonography,magnetic resonance and CTU examination showed 8 patients were complicated with urethrovaginal fistula,and 1 patient was complicated with vaginorectal fistula. All patients underwent transpubic access and resection of symphysis pubis. According to the specific conditions of urethral stricture,7 of them underwent end-to-end urethral anastomosis,5 cases underwent bladder wall flap urethroplasty,3 cases underwent vulva flap urethroplasty,8 cases underwent urethral vaginal fistula repair,1 case underwent vagino-rectal fistula repair,and 7 cases underwent vaginoplasty during the operation.Results:All the 15 patients underwent successful operation without complication. After the catheter being removed 4 weeks after surgery,2 patients had urgent urinary incontinence and 3 patients had stress urinary incontinence. The bladder neck was reconstructed 3 months after surgery,the symptoms of urinary incontinence improved in 1 case,urinary incontinence remained in 2 cases,and pharmaceutical or physical therapy were continued. Two patients could not urinate normally after the catheter was removed and still carried the vesicostomy tube,waiting for further treatment. The other 8 patients had unobtrusive voiding after extubating,and were followed up for an average of(22.5±3.2)months. There was no recurrence of urinary fistula,and the average maximum urinary flow rate was(22.8±3.2)ml/s.Conclusions:The transpubic approach is a safe and effective way to treat female genital tract injury by different surgical methods according to specific conditions,especially for patients with severe trauma,poor local tissue conditions,complicated urethrovaginal fistula or vagino-rectal fistula.

Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emodin may inhibit oncogenes YAP1 and FOXD1 through the glycolytic metabolism of gastric cancer AGS cells.

Due to the ongoing outbreak of COVID-19, we reflect on the optimization of teaching content and the guidance to deep learning, from the perspective of TCM teaching research. We believe that it's necessary to pay attention to the overall integration of TCM theories, academic researching, and clinical practicing when teaching. By excavating and sorting out the knowledge system of TCM, a clear conceptual pedigree of academic inheritance is constructed. In the teaching of traditional Chinese pharmacy, we should integrate the reconsideration and multi-dimensional research on the theory of medicinal properties, and make preparations for the development of Chinese medicine in a new direction through the cross-integration of various disciplines.

PURPOSE: The prevalence of PIK3CA in Chinese breast cancer patients may be underestimated. Therefore, we investigated the distribution of somatic PIK3CA/AKT1 mutations in Chinese breast cancer patients and explored their roles in tumor phenotypes and disease prognosis. MATERIALS AND METHODS: Tumors from 507 breast cancer patients were prospectively collected from the West China Hospital between 2008 and 2013. Whole exons of AKT1 and PIK3CA were detected in fresh-frozen tumors using next-generation sequencing, and correlations between PIK3CA/AKT1 mutations and clinicopathological features were analyzed. RESULTS: The AKT1 mutation was found in 3.6% (18/507) of patients. Tumors from patients that carried the AKT1 mutation were estrogen receptor (ER)+/progesterone receptor (PR)+/human epidermal growth factor receptor 2 (HER2)‒ and were more likely to have high expression levels of Ki67. The prevalence of the PIK3CA mutation was 46.5% (236/507), and 35 patients carried two or three variants of the PIK3CA gene. PIK3CA mutations were associated with ER+/PR+/HER2‒ status. The prognosis of patients with one mutation in PIK3CA (or PIK3CA/AKT1) was not significantly different than that of patients with wild-type PIK3CA (or PIK3CA/AKT1), while patients with two or three variants in PIK3CA (or PIK3CA/AKT1) exhibited poorer outcomes in the entire group and in all three subgroups (ER+, HER2‒, Ki67 high), particularly with respect to overall survival. CONCLUSION: A high frequency of somatic PIK3CA mutations was detected in Chinese breast cancer patients. In addition to the mutation frequency, the tumor mutational burden of the PIK3CA and AKT1 genes should also be of concern, as they may be associated with poor prognosis.

Objective To explore the effects of "3+1+1" talent cultivation model on key competency in five-year higher vocational nursing students. Methods In March 2015, we selected five-year 80 higher vocational nursing students majoring in clinical nursing in 2013 of Wuxi Higher Health Vocational Technology School as subjects by convenience sampling. All of the 80 nursing students were divided into experimental group (n=38) and control group (n=42) according to classes. Nursing students of experimental group received the "3+1+1" talent cultivation model. Nursing students of control group were treated with the "4+1" cultivation model. The evaluation index system for key competency of five-year higher vocational nursing students was used to evaluated nursing students of two groups. We also compared the theoretical achievement and skills performance of nursing students between two groups. Results There were no statistical difference in key competency of nursing students between two groups at the end of the 2.5th school year (P>0.05). The score of key competency of nursing students in experimental group was higher than that in control group at the end of the fourth school year with a significant difference (P< 0.05). There were no statistical differences in theoretical achievement and skills performance of nursing students between two groups at the end of the 2.5th school year (P>0.05). The theoretical achievement and skills performance of nursing students in experimental group were higher than that in control group at the end of the fourth school year with significant differences (P< 0.05). Conclusions The "3+1+1" talent cultivation model can improve nursing students' key competency and school achievement.

Objective To investigate the safety and efficacy of ultrasound ablation in treatment of uterine fibroids. Methods Ninety-nine patients with 117 leiomyomas in total treated by Haifu JC focused ultrasound tumor therapeutic system were enrolled in prospective and non-randomized clinical trial in First Affiliated Hospital of Chongqing Medical University and Academy of Military Medical Sciences. Ultrasound ablation was performed guided by real-time ultrasonography under conscious sedation for single session. All patients were followed up at 6 months after treatment. On the day of treatment and after 1 month, patients were given by magnetic resonance imaging(MRI) exam to evaluate the effect of fibroids ablation. At 3 and 6months after treatment, the ratio of ablated area and volume reduction of fibroids more than 50% were evaluated by MRI exam again. The symptoms improvements were evaluated by uterine fibroid symptom (UFS) and complications were analyzed by guideline of society of international radiation (SIR). Results The average ablated area ratio of the target fibroid was (76 ± 24)%. The average reduction in fibroid volume determined by MRI at 3 and 6 months after treatment was (45 ± 21)% and (59 ± 26)%. Which were significantly decreased than those before treatment (P < 0. 05). At 6 months after treatment, 84. 6% (99/117) of patients showed more than 50% volume reduction, the rate of improved symptom score was 92%(66/72). All patients could resume normal daily activities at 2 hours after treatment. The adverse reactions of SIR C - D included delayed hospitalization, repeat treatment and increased level of nursing. E - F included permanent sequelae and death. In this study, no adverse reactions of C - F were recorded. Common complications (SIR A- B, only observation or simple management without sequelae) were 35% (35/99).Four cases with adverse reactions B of SIR were found, including 2 cases with skin burning of degree Ⅱ and 2 cases with febrile, they were administered by symptomatic therapy and changing dressing The other adverse reaction A of SIR included sorness of buttock, vaginal discharge, dysuria and painful urination, they were only suggested by follow-up. Conclusion It was efficacy and safe that ultrasound ablation as a single strategy were used in treatment of uterine fibroids.
