Objective:To summarize the surgical strategies and to evaluate the clinical outcomes of up-per urinary tract reconstruction in patients with stone-related ureteral strictures.Methods:This retro-spective study included 71 patients diagnosed with ureteral strictures secondary to urinary stones who un-derwent upper urinary tract reconstructive surgery at Peking University First Hospital between March 2014 and November 2023.Patient data were collected,including demographic characteristics,clinical presen-tation,laboratory results,imaging findings,surgical procedures,and follow-up outcomes.Ureteral stric-tures were classified according to anatomical location into upper,middle,lower,or multiple segments.Surgical procedures were carried out depending on the stricture characteristics.Surgical success was de-fined as resolution or improvement of clinical symptoms,radiographic improvement or stabilization of hy-dronephrosis,and maintenance of normal and stable renal function.Results:Among the 71 patients,36(50.7％)had strictures in the upper ureter,9(12.7％)in the middle ureter,15(21.1％)in the lower ureter,and 11(15.5％)had multifocal ureteral strictures.The median stricture length was 5.0 cm(interquartile range:3.0-15.0 cm).Surgical approach selection was individualized based on the location and extent of the stricture.For upper ureteral strictures,the most frequently employed techniques were oral mucosal graft ureteroplasty(13/36,36.1％)and appendiceal flap ureteroplasty(8/36,22.2％).Other options included ureteroureterostomy and ileal ureter replacement for longer or more complex strictures.In middle ureteral strictures,treatment was stratified by length:balloon dilation(1/9,11.1％)and ureteroureterostomy(1/9,11.1％)were applied in shorter strictures,while oral mucosal graft ureteroplasty(3/9,33.3％)and ileal ureter replacement(4/9,44.4％)were reserved for longer segments.For lower ureteral strictures,ureteral reimplantation into the bladder was the most common approach(10/15,66.7％),often combined with a psoas hitch or Boari flap when necessary.All the patients with multiple segmental strictures underwent ileal ureter replacement due to the extensive nature of the disease.The median follow-up period was 14.2 months(range:6.1-107.1 months).During follow-up,69 of 71 patients(97.2％)achieved surgical success.Conclusion:Stone-related ure-teral strictures present with considerable heterogeneity in terms of anatomical location,length,and com-plexity.Careful preoperative evaluation and individualized surgical planning are critical to successful re-construction.With appropriate selection of surgical methods,favorable long-term clinical outcomes can be achieved in the majority of patients.

Objective To observe the clinical efficacy of Shengdi Xiexin Decoction combined with proton pump inhibitors(PPIs)in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB)with stomach-heat congestion syndrome.Methods Sixty-two patients with ANVUGIB of stomach-heat congestion syndrome admitted to Dongguan Hospital of Guangzhou University of Chinese Medicine between January and December 2024 were randomly divided into a treatment group(n=31)and a control group(n=31)using a random number table.The control group received conventional western therapy(e.g.,Omeprazole Sodium),while the treatment group additionally received Shengdi Xiexin Decoction.Both groups were treated for 7 days,followed by 8 weeks of follow-up.The changes in traditional Chinese medicine(TCM)syndrome scores,hematological parameters[hemoglobin(Hb),red blood cells(RBC),hematocrit(Hct),albumin(ALB)],tissue perfusion and metabolic markers[blood urea nitrogen/creatinine ratio(BUN/Cr),lactate(Lac)levels],hemostasis time,time to resume oral diet,hospital stay duration,hospitalization costs,and rebleeding rates were observed to evaluate the clinical efficacy and drug safety.Results(1)After 7 days of treatment,the total effective rate was significantly higher in the treatment group(90.32％,28/31)than that in the control group(74.19％,23/31).The intergroup comparison(by chi-square test)showed that the treatment group,efficacy was superior to that of the control group(P＜0.05).(2)The treatment group showed significantly short hemostasis time,time to resume oral diet,and hospital stay duration(P＜0.05),as well as significantly low hospitalization costs(P＜0.05)compared to the control group.(3)Both groups exhibited significant reductions in the scores of epigastric burning pain,abdominal distension,acid regurgitation,restlessness,excessive thirst,scanty dark uring and dry stools,and total TCM syndrome scores(P＜0.05).The treatment group demonstrated significantly greater improvements in the scores of abdominal distension,acid regurgitation,restlessness,dark uring and dry stools,and total TCM syndrome scores(P＜0.05),while no significant differences were observed in epigastric burning pain and excessive thirst(P＞0.05).(4)Hb and Hct levels increased significantly in both groups(P＜0.05),with a greater increase in the treatment group(P＜0.05).Although RBC and ALB levels showed an upward trend,no significant differences were observed between groups(P＞0.05).Following treatment,intergroup comparisons revealed that the treatment group demonstrated significantly greater increases in Hb and Hct levels than the control group(P＜0.05).In contrast,the two groups showed comparable effects in elevating RBC and ALB levels,with no statistically significant differences(P＞0.05).(5)BUN/Cr ratio and Lac levels decreased significantly in both groups(P＜0.05),with a more pronounced reduction in the treatment group(P＜0.05).(6)No significant differences were found in early or delayed rebleeding rates between groups(P＞0.05).(7)Neither group experienced significant adverse events.Conclusion Shengdi Xiexin Decoction combined with PPIs significantly improves clinical outcomes in ANVUGIB patients with stomach-heat congestion syndrome.It is effective on enhancing hematological parameters,correcting tissue hypoperfusion,alleviating symptoms,shortening hemostasis time and hospitalization durations,and reducing medical costs,demonstrating excellent safety.

Objective:To compare the application effects of electric impedance tomography (EIT)-guided positive end-expiratory pressure conventional PEEP and PEEP-fraction of inspired oxygen (FiO 2) table-guided PEEP in the mechanical ventilation of patients with traumatic brain injury (TBI) complicated with acute respiratory distress syndrome (ARDS). Methods:A retrospective cohort study was conducted on the clinical data of 80 TBI patients complicated with ARDS admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from July 2020 to December 2022, including 42 males and 38 females, aged 29-59 years [(42.4±7.8)years]. The Glasgow coma scale (GCS) scores were 3-12 points [(7.7±2.2)points]. According to ARDS classification, 33 were mild, 26 moderate and 21 severe. All the patients were treated with mechanical ventilation according to lung protective ventilation strategy, including 42 patients treated with EIT-guided PEEP (EIT group) and 38 treated with conventional PEEP-FiO 2 table-guided PEEP (conventional group). At 12 hours, 1, 3 and 5 days after ventilation, the optimal PEEP, respiratory mechanics [driving pressure (ΔP), static compliance (C St), mechanical power (MP)], pulmonary gas exchange [arterial blood pH value, arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (P/F)], ventilation distribution [heterogeneity index (GI), regions of interest (ROI)1-4], hemodynamics [heart rate (HR), central venous pressure (CVP), mean arterial pressure (MAP)], cerebral perfusion status [intracranial pressure (ICP), regional cerebral oxygen saturation (rScO 2) grading], and treatment outcomes (mechanical ventilation duration, incidence of ventilator-induced lung injury (VILI), length of ICU stay, 6-month survival rate) separately at their optimal PEEP were compared between the two groups. Results:All the patients were followed up for 6 months. The optimal PEEP of the EIT group was (7.4±1.0)cm, (8.2±1.2)cm, (9.8±0.8)cm and (8.4±0.7)cm respectively at 12 hours, 1, 3 and 5 days after mechanical ventilation, which were higher than (7.0±1.0)cm, (7.6±1.0)cm, (9.0±0.6)cm and (7.2±0.5)cm of the conventional group ( P<0.05 or 0.01). At their optimal PEEP separately, at 12 hours, 1, 3 and 5 days after treatment, the ΔP of the EIT group was (7.1±1.3)cmH 2O, (7.7±1.3)cmH 2O, (9.5±1.1)cmH 2O and (6.1±1.3)cmH 2O respectively, which were all lower than (8.9±1.3)cmH 2O, (10.5±1.3)cmH 2O, (11.2±1.2)cmH 2O and (8.7±1.2)cmH 2O of the conventional group respectively ( P<0.05 or 0.01); the C St of the EIT group was (51.5±4.2)ml/cmH 2O, (52.9±4.6)ml/cmH 2O, (55.1±4.3)ml/cmH 2O and (57.5±3.6)ml/cmH 2O, which were all higher than (46.8±3.9)ml/cmH 2O, (47.6±4.4)ml/cmH 2O, (49.9±4.3)ml/cmH 2O and (53.3±3.6)ml/cmH 2O of the conventional group respectively ( P<0.05); the MP of the EIT group was (7.9±1.8)J/min, (8.8±1.3)J/min, (10.6±1.3)J/min and (7.8±0.9)J/min, which were lower than (8.6±1.5)J/min, (9.5±1.0)J/min, (12.2±1.8)J/min and (8.6±0.9)J/min of the conventional group respectively ( P<0.05 or 0.01); the P/F of the EIT group was (207.1±7.1)mmHg, (213.1±6.9)mmHg, (239.3±13.1)mmHg and (255.5±11.8)mmHg, which were all higher than (179.6±7.2)mmHg, (187.8±9.6)mmHg, (212.8±9.6)mmHg and (228.1±12.3)mmHg of the conventional group respectively ( P<0.05 or 0.01); the GI of the EIT group were 0.381±0.013, 0.387±0.012, 0.392±0.010 and 0.395±0.010, lower than 0.403±0.005, 0.406±0.005, 0.409±0.005 and 0.411±0.004 of traditional group respectively ( P<0.01); there were no significant differences in the arterial blood pH value, PaCO 2, ROI1-4, HR, CVP, MAP, ICP, or rScO 2 grading between the two groups (P>0.05). The ventilation duration of the EIT group was (78.5±9.0)hours, which was shorter than (83.1±7.4)hours of the conventional group ( P<0.05). The incidence of VILI was 0.0% (0/42) in the EIT group, which was lower than 7.8% (3/38) in the conventional group ( P<0.05). There were no significant differences in the ICU stay or 6-month survival rate between the two groups ( P>0.05). Conclusions:In mechanical ventilation treatment of TBI complicated with ARDS, the optimal PEEP guided by EIT was higher than that guided by PEEP-FiO 2 table. At this optimal PEEP, the respiratory mechanics and oxygen supply of the patients can be improved more effectively, making regional lung ventilation more uniform, reducing the mechanical ventilation time and decreasing the incidence of VILI without affecting their hemodynamics and brain perfusion.

Objective:To explore the economic applicability and safetyof the novel uterovaginal pubic comb suspension(UPCS)surgery with Mersilene tape in the treatment of pelvic organ prolapse(POP).Methods:A ret-rospective analysis was conducted on the clinical data of patients who underwent UPCS surgery due to POP from January 1st,2021 to February 28,2023.They were divided to the UPCS surgery with Mersilene tape group(group A)and suspension surgery with Y-shaped mesh group(group B)respectively.The POP-Q indication points,sus-pension surgery duration,intraoperative bleeding volume,material expense,postoperative catheter retention time,anal exhaust time and hospitalization duration were recorded for both groupbefore and after surgery.Evaluate the severity of POP related symptoms in patients before and after surgery using the pelvic Floor Distress Invento-ry-short Form 20(PFDI-20)and Pelvic Organ Prolapsed/Urinary Incontinence Sexual Questionnaire-12(PISQ-12),and follow up and observe the patients and analyze the complications.Results:A total of 17 POP patients were included in the study.There were 12 patients in group A while 5 patients in group B.The suspension material expense of group A was considerably lower than that of group B(P＜0.05).There was no significant difference between the two groups in preoperative PFDI-20 score,preoperative PISQ-12 score,UPCS surgery duration,intr-aoperative bleeding volume,postoperative urinary catheter retention time,postoperative anal exhaust time and hospitalization duration.All patients showed stable vital signs during the surgery and no severe complications were reported.Compared with the preoperative status,the positions of the Aa,Ba,and C indicatorpoint in group A and group B were all increased significantly(P＜0.05).The PFDl-20 and PISQ-12 scores of the two groups at the last follow-up after surgery showed significant improvement compared to those before surgery(P＜0.05).No signifi-cant difference was found in the PFDI-20 and PISQ-12 scores between the two groups after surgery(P＞0.05).There were no significant differences in the postoperative complications between the two groups(P＞0.05).Con-clusions:Compared with suspension surgery with Y-shaped mesh,UPCS surgery with Mersilene tape is safe and effective in the treatment of POP.The UPCS surgery with Mersilene tape showed better cost-effectiveness in the treatment of POP,and the surgical steps are relatively simple.Therefore,UPCS surgery with Mersilene tape was worthy of promotion in clinical practice.

Objective:To observe the changes of nutrition impact symptoms (NIS) and fat-free mass and analyze the relationship between them in patients with head and neck cancer (HNC) during radiotherapy.Methods:A convenient sampling method was adopted to select HNC patients who received radiotherapy in the outpatient clinic of department of radiotherapy for head and neck cancer in a cancer hospital in Beijing from March 2017 to January 2020. The nutrition impact symptoms (NIS) were assessed by a nutrition impact symptoms checklist and the fat free mass was assessed by bioelectrical impedance analysis at three time points: before radiotherapy (T1), during radiotherapy (T2) and at the end of radiotherapy (T3). The Generalized Estimating Equations (GEE) was used to analyze the relationship between them.Results:A total of 542 HNC patients were included in the analysis. During radiotherapy, the patients' NIS number and score presented an increasing trend, reaching the highest level and peaked at the end of radiotherapy. The change of fat-free mass showed a decreasing trend and reached the minimum at the end of radiotherapy. Patients with higher NIS scores had more percentage loss of fat-free mass.Conclusions:During radiotherapy, patients with HNC showed an increase in NIS score and lost fat-free mass. Patients with higher NIS score lost more percentage of fat-free mass, which suggested that clinical medical staff should pay attention to NIS management and take comprehensive intervention measures in time to reduce the loss of fat-free mass.
