ABSTRACT
Objective:To investigate the effect of polyene phosphatidylcholine combined with Shudan decoction on the recovery of gallbladder function after gallbladder-preserving cholecystolithotomy.Methods:Sixty patients with gallbladder stone admitted to Shenzhen Hospital (Longgang), Beijing University of Chinese Medicine from June 2018 to July 2021 were selected. All patients were received gallbladder-preserving cholecystolithotomy, and they were divided in two groups by random number table, each group with 30 patients. The control group was treated with polyene phosphatidylcholine capsule after the operation, while the observation group was treated with Shudan decoction on the basis of the control group. After 30 d of continuous treatment, the traditional Chinese medicine symptoms score, gallbladder contraction function and the levels of serum alkaline phosphatase (ALP), gamma-glutamine transferase (GGT), incidence of adverse reactions, clinical efficacy were compared between the two groups.Results:After treatment, the scores of abdominal distension, abdominal pain and anorexia in the observation group were lower than those in the control group ( P<0.05). After treatment, the thickness of the gallbladder wall in the observation group was lower than that in the control group and the the gallbladder contraction rate was higher than that in the control group: (2.62 ± 0.29) mm vs. (3.21 ± 0.32) mm, (74.17 ± 6.49)% vs. (62.03 ± 6.05)%, there were statistical differences ( P<0.05). After treatment, the levels of GGT and ALP in the observation group were lower than those in the control group: (132.32 ± 30.09) U/L vs. (150.27 ± 30.33)U/L, (56.12 ± 14.89) U/L vs. (75.07 ± 16.22) U/L, there were statistical differences ( P<0.05). The total effective rate in the observation group was higher than that in the control group: 96.67%(29/30) vs. 80.00%(24/30), there was statistical difference ( χ2 = 4.04, P<0.05). The adverse reactions in the two groups had no significant differences ( P>0.05). Conclusions:Polyene phosphatidylcholine combined with Shudan decoction has a definite efficacy for patients with cholecystolithiasis after gallbladder-preserving cholecystolithotomy, and can effectively promote the recovery of their gallbladder function and with good safety.
ABSTRACT
【Objective】 To explore the clinical features, treatment and prognosis of paraganglioma of the urinary bladder (PUB). 【Methods】 The clinical data of 41 PUB patients treated at our hospital during Sep.2012 and Sep.2022 were collected. The clinical features, surgical records, pathological reports and follow-up records were retrospectively analyzed. Patients’ survival was estimated with Kaplan-Meier estimator. The differences among groups were compared with Log-rank test. 【Results】 Among the 41 patients, 20 were male and 21 were female, with a median age of 52 years. All patients were treated with surgery, including transurethral resection of bladder tumor (TURBT) in 16 cases, partial cystectomy (PC) in 23 cases, and radical cystectomy (RC) in 2 cases. All patients were followed up for 4.0 to 125.0 months, with a median of 59.0 months. Local recurrence occurred in 5 patients, and distant metastasis occurred in 5 patients. Survival analysis showed that the 5-year overall survival (OS) rate and 5-year relapse-free survival (RFS) rate were 95.7% and 84.8%, respectively. Further analysis showed statistically significant differences in OS and RFS among groups with different maximum tumor diameters, growth patterns, and Ki-67 expressions (P<0.05). For patients with a maximum tumor diameter ≤2.8 cm, there was no significant difference in OS and RFS among different surgical groups. 【Conclusion】 PUB is rare, and a definitive diagnosis is based on pathology. In addition, the main treatment is surgery and the prognosis is good.

ABSTRACT
Objective To compare the therapeutic effect of video-assisted thoracoscopic surgery and traditional thoracotomy in fixation of traumatic multiple rib fractures.Methods Clinical data of 56 patients with traumatic multiple rib fractures treated surgically between July 2005 and September 2012 were analyzed retrospectively.Based on the treatments,the patients were assigned to video-assisted thoracoscopy group (thoracoscopy group,n =27) and traditional thoracotomy group (thoracotomy group,n =29).A comparison was done on the variables including operation time,intraoperative blood loss,ventilator support rate,duration of mechanical ventilation,length of ICU stay,incidence of lung infections,visual analogue scale (VAS) at day 3 postinjury and mortality between the two groups.Results Operation time [(128.9 ± 21.1) min vs (140.7 ± 24.2) min],ventilator support rate (70％ vs 76％) and mortality (4％ vs 7％) in thoracoscopy group revealed no statistical differences compared with thoracotomy group (P ＞ 0.05),but intraoperative blood loss [(321.1 ± 30.1)ml vs (438.1 ± 43.2)ml],duration of mechanical ventilation [(4.3 ± 2.1) d vs (7.2 ± 1.6) d],length of ICU stay [(5.9 ± 21.1) d vs (8.5 ± 1.7) d],incidence of lung infection (33％ vs 90％),and VAS [(7.0 ± 1.4) points vs (8.3 ± 0.9) points] were significantly reduced in thoracoscopy group than in thoracotomy group (all P ＜ 0.01).Conclusion Video-assisted thoracoscopic surgery is characterized by fewer intraoperative bleeding,shorter duration of mechanical ventilation and ICU stay,and lower lung infection rate during treatment of traumatic multiple rib fractures compared to traditional thoracotomy.
ABSTRACT
The clinical data of 30 patients with vesical calculus of 1.5 cm to 4 cm in diameter,who underwent combination of transurethral pneumatic and ultrasonic cystolithotripsy,were retrospectively analyzed.During the procedure the resectoscopic sheath was inserted into bladder through urethra,then the nephroscope was placed through the sheath.When the stone was located,the ultrasonic and pneumatic devices were used for lithotripsy and the fragments were cleared out.The procedures lasted from 10 to 25 min,all operations were successful.Transurethral resection of prostates (TURP) was performed simultaneously in 28 patients.No serious bleeding,bladder injury or transurethral resection syndrome occurred.One patient with simultaneous TURP developed bladder neck contracture one month after surgery and was later cured by endoresection.No residual chip or stone recurrence was detected.This procedure appears to be safe and highly efficient with low rate of urethrostenosis and is suitable for simotaneous prostate surgery.
ABSTRACT
ObjectiveTo investigate the surgical management of left renal vein entrapment syndrome.MethodsEight cases with left renal vein entrapment syndrome (5 males and 3 female ; mean age 26 years) with history of gross hematuria for 3 to 46 months were reviewed.Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all cases.And the dilated segment of the left vein was three-fold than the stricture segment in diameter.CT scan showed the abnormal angle between aorta and superior mesentery artery in all cases.Bleeding from the left ureteral orifice was detected by cystoscopy in 6 cases.We treated 8 patients by extravascular stent immobilization with laparoscope.ResultsThe operation was successful in the 8 cases without surgical complications.The average operation time was 63 min.The average blood loss was 14 ml,and the average hospital stay after operation was 6 days.Follow-up of 3 -20 months,there was no hematuria relapse since been relieved in 7 cases,one case remained microscopic hematuria.Color Doppler ultrasound examination in all 8 cases showed the narrowest inner diameter of left renal vein was 7.4 mm (6.5 - 8.7 mm),the blood flow was smooth.The angle between abdominal aorta and superior mesenteric artery become normal.Conclusions Laparoscopic left renal vein extravascular stenting could be a new surgical method to treat left renal vein entrapment syndrome.The method of putting artificial blood vessel around renal vein is simple,safe and effective.
ABSTRACT
Objective To assess the value of the urine flow acceleration(UFA)versus maximum urinary flow rate (Qmax) for diagnosis of bladder outlet obstruction (BOO) in benign prostate hyperplasia (BPH).Methods A total of 50 men with BPH and 50 normal men were included in this study.Urodynamic examinations were performed in all patients according to the recommendations of the International Continence Society.Prostate volume,UFA and Qmax of each patient were analyzed and the results were compared between two groups.Results The UFA and Qmax of BPH group were much lower than that of the control group [(2.05±0.85)ml/s2 vs.(4.60±1.25)ml/s2 ; (8.50±1.05)ml/s vs.(13.00±3.35)ml/s,P＜0.05].The prostate volume in BPH group was increased compared with control group [(28.6±9.8) ml vs.(24.2±7.6)ml,P＜0.05].As diagnosis standard of UFA＜2.05 ml/s2 and Qmax＜ 10 ml/s,the sensitivity and specificity of UFA and Qmax in diagnosing BOO were (88％,75 ％)vs.(81％,63％).While compared with the result of P-Q chart,the Kappa values in correspondence analysis were 0.55 vs.0.35.The sensitivity,specificity and Kappa value of UFA in diagnosing BOO in BPHs were slightly higher than that of Qmax in comparison with the gold standard (BOO diagnosed by P-Q figure).Conclusions The UFA is a useful urodynamics parameter in diagnosing BOO of BPH.
ABSTRACT
Objective To investigate the effects of solifenacin on the detrusor instability of patients with overactive bladder (OAB).Methods A total of 20 outpatients with OAB of.1 - 20 ( mean, 8 )years, 12 males and 8 females, aged 21 - 83 ( mean, 43) years were included in this study.Five mg solifenacin was given orally once daily for 12 weeks.Before and after treatment, overactive bladder symptom score (OABSS), patient perception of bladder condition symptoms rating scale (PPBC), and filling cystometry was performed.Results Before and after solifenacin administration, significant decrease were detected in term of unstable detrusor waves ( 2.3 ± 2.4) vs (0.6 ± 1.3 ) ( P ＜ 0.05 ), and detrusor overactivity ( DO ) disappeared in 6 patients.Bladder capacities at first desire to void and maximum bladder capacity were significantly increased (P ＜0.01 ).Bladder compliance and detrusor pressure at maximum urine flow had no significant difference (P ＞ 0.05 ).All patients had significant improvement in OAB symptoms evaluating by OABSS and PPBC ( P ＜ 0.05 ).Six patients had mild side effect of dry mouth and could be relieved by drinking more water.Conclusion Urodynamically, solifenacin decreases the detrusor overactivity, increases the bladder capacity and improves the quality of life of OAB patients.
ABSTRACT
Objective To investigate the clinical efficacy of pedicled adrenal transposition for the treatment of adrenocortical and medullary hyperplasia, Methods Twenty cases of adrenal hyperpla-sia (6 men and 14 women; mean age,36 years ) had history of hypertension from 0.5 to 5 years. Of all cases, 15 had centripetal obesity and purple striae, 2 had weakness and polyuria, 3 had durative hypertension. Serum potassium and aldosterone were increased in 4 and 3 cases, respectively. Urinary 17-OH and 17-KS were increased in 15 cases. Epinepgrine, norepinephrine and dopamine increased in 3 cases, VMA increased in 4 cases. CT scan and MRI revealed adrenal diffuse enlargement with in-creased thickness or nodules in 18 and 3 cases, respectively, 131I-MIBG scan showed positive in 3 ca-ses. Preoperative diagnoses were Cushing's syndrome in 11 cases, hyperaldosteronism in 2 cases, pheochromocytoma in 1 case, adrenomedullary hyperplasia in 2 cases, Cushing's syndrome-cate-cholamine syndrome in 4 cases. All cases were treated with transposition of pedicled adrenal gland into the subcutaneous tissues. Results All operations were successful. The average operation time was 120 min, the average blood loss was 40 ml and the average hospital stay was 10 d. No obvious surgical complications occurred. Pathological studies of all the cases revealed the coexistence of adrenocortical and medullary hyperplasia. Seventeen cases were followed up for 0.5-8 years. Thirteen cases had no symptom and normal biochemical results. Four cases still had hypertension and abnormal biochemical results. They were recovered after adrenal operation of the ther side. Conclusion Transposition of pedicled adrenal gland could be an available option to treat patients with adrenocortical and medullary hyperplasia.
ABSTRACT
Objective To explore the clinical efficacy of artificial blood vessel sheath around re-nal vein for the treatment of left renal vein entrapment syndrome. Methods Eight cases with left re-nal vein entrapment syndrome (7 males and 1 female, mean age, 16 years) with history of gross hema-turia for 6 to 36 months were reviewed. Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all eases. CT scan showed the abnormal angle between aorta and su-perior mesenterie artery in 5 cases. Cystscopy showed hematuria from the left ureteral orifice in 5 ca-ses. All cases with left renal vein entrapment syndrome were treated ,with the method of putting artifi-cial blood vessel as a sheath around left renal vein. Results The operations were all successful. The average operation time was 150 min, the average blood loss was 50 ml, and the average hospital stay after operation was 9 d. No surgical complications occurred. The gross hcmaturia disappeared in 6 ca-ses and Doppler ultrasound showed that left renal vein outflow was normal in 7 when the patients dis-charged from the hospital. The gross hematuria disappeared during 2-24 months' follow-up in 7 pa-tients. Conclusions The surgical aim of renal vein entrapment syndrome is to reduce the compres-sion of renal vein. The method of putting artificial blood vessel around renal vein could be a simple, safe and effective method.

ABSTRACT
An enzyme electrode biosensor was used for the amperometric determination of inosine in its tablets by co-immobilizing nucleoside phosporylase and xanthine oxidase on a hydrogen peroxide electrode. As a fundamental electrode the hydrogen peroxide electrode has an advantage of stability in analysis compared with the 02 electrode. The enzyme electrode showed a linear response to inosine in the range of 1-268 mg/L with a response of 60 seconds under a sample injection volume of 25 microL. Based on the enzyme electrode, inosine solutions were determined with an average recover rate of 100.8% and a relative standard deviation (RSD) of les than 0.14% in 20 assays. The lifetime of the enzyme electrode was relative long and could be used continuously at 25 degrees C for 25 days. These results demonstrated that the enzyme electrode biosensor could be used to determine inosine and its derivatives specifically, rapidly, conveniently and economically.
