Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.

Objective: To analyze the main causes for unplanned re-operation of prostatic cancer. Methods: The clinical data of 4 patients with prostatic cancer who underwent an unplanned re-operation were analyzed retrospectively between September 2014 and July 2019 in our hospital.Preoperative data of patients was collected as follows: mean age of 65 years, ranged from 56 to 71 years.tPSA ranged from 5.17-13.20 ng/ml.Gleason score of 3+ 3 in 1 case, 3+ 4 in 2 cases, 4+ 4 in 1 case. pTNM pT_2a in 2 Cases, pT_2b in 2 cases. LRP(extraperitoneal approach) in 1 case, RARP(transperitoneal approach) in 3 cases. Results: The main causes for unplanned re-operation were as follows: perioperative hemodynamic instability(75%, 3/4), post-operative fever(25%, 1/4). All 4 re-operations were performed by urologists using Laparoscopic exploration of abdomen. Conclusions Inadequate and inappropriate surgical hemostasis are the key to lead a second-look surgery of prostatic cancer.A complete hemostasis could help to lower the re-operation rate.Laparoscopic exploration of abdomen could be one of the choices to deal with re-operation after minimally invasive radical prostatectomy.

OBJECTIVETo determine the effect of body mass index (BMI) at baseline and its change during follow-up on the incidence of non-alcoholic fatty liver diseases (NAFLD) in apparently healthy adults.

METHODSSubjects free of previous liver injury, alcohol consumption of more than 140 g/week and hepatitis B virus infection were identified from employees of Shanghai BaoSteel Group who underwent voluntary medical checkups at a 2-year interval. The analyzed population consisted of 5402 non-drinking subjects (4633 men) of age 36.5+/-9.3 years (18-65 years), who had normal livers at baseline. Among them 327 subjects (6.05%) developed fatty liver in 2 years. Those who developed NAFLD showed advanced age (especially in females), elevated BMI, high levels of serum triglyceride and total cholesterol, high prevalence rates of obesity, hyperlipidemia, hypertension and hyperglyceridemia at baseline, more weight gain and increase of serum triglycerides during the 2-year period. The incidence of NAFLD increased significantly with the changes of BMI at baseline, from 1.4% in subjects with normal weight, 6.4% in overweight, 16.8% in obese patients to 24.5% in severe obesity (Chi2 test = 389.01, P = 0.000 in trend analysis). Logistic regression analysis showed a significant interaction occurred between NAFLD age, BMI and serum triglyceride at baseline, and subtle gain of BMI and triglyceride during follow-up.

CONCLUSIONSThere is a high incidence of NAFLD in a Chinese workplace. Obesity and related metabolic disorders at baseline, and more weight gain and increased serum triglyceride during follow-up are important predictors for the development of NAFLD.

Objective To establish a rat liver transplantation model under direct vision of single operator and to explore the effect of different perfusion methods on the quality of the donor liver. Methods On the basis of the "two-cuff method" established by Kamada, the operation details were improved to established the rat liver transplantation model. The recipient rats were divided into two groups according to different perfusion methods, group A (perfusion via abdominal aorta) and group B (perfusion via portal vein). The perfusion effect, operation time, operation success rate, postoperative liver function, liver graft pathological manifestations and survival were compared between the two groups. Results There were more residual red blood cells in sinus hepaticus in group B than in group A after perfusion. Both the donor liver perfusion time and donor operation time were longer in group A than those in group B, and the differences were statistically significant (both P < 0.01). The success rate of operation in group A and group B was 77% and 71%, respectively. At 3 d after liver transplantation in rats, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TB) of the rats in the two groups were significantly higher than normal. At 7, 30 d after operation, compared with group A, the levels of ALT, AST and TB in group B were significantly increased, and the differences were statistically significant (all P < 0.01-0.05). The liver pathological examination showed that the degree of inflammatory reaction in the liver and degree of destruction of liver tissue in group B were more severe than those in group A, but there was no significant difference in long-term survival rate between the two groups. Conclusions Although the perfusion time and donor operation time of rat liver transplantation model were slightly prolonged by means of abdominal aorta perfusion, the perfusion effect was better, which can reduce liver tissue damage after operation and restore liver function to normal levels more quickly.

Objective To study the influence of HBV-DNA with different load levels of HBsAg-positive among fathers on the rate of neonatal cord blood HBV-DNA.Methods Using HBsAg and HBV-DNA as screening indicators for pregnant women and their husbands from an obstetric clinic.161 pregnant women whose HBsAg and HBV-DNA were negative,but HBsAg was positive among their husbands and their newborns,were selected.Blood samples from those pregnant women,their husbands and their newborns were collected to detect the related indicators.Using ELISA to detect hepatitis B virus markers(HBVM),and FQ-PCR to detect the levels of HBV-DNA load.According to neonatal cord blood HBV-DNA detection guideline,newborns with cord blood HBV-DNA positive were selected as cases,others as controls.Results(1)Result of the study showed that there was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive rates in newborns(trend χ~2=64.117,P=0.000).The rate of vertical transmission of HBV from HBsAg-positive father to infant in the paternal serum HBV-DNA＞1.0×107 copies/ml group was significantly higher than HBV-DNA＜1.0×107 copies/ml group(χ~2=71.539,P=0.000).(2)There was a positive rank correlation between semen positive HBeAg and vertical transmission of HBV from HBsAg-positive father to infant(χ~2=6.892,P=0.009).Conclusion There was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive in newborns.Paternal serum HBV-DNA≥1.0×107 copies/ml and with HBeAg positive status were risk factors of vertical transmission of HBV from HBsAg-positive father to infant.

OBJECTIVETo investigate the effects of health Qigong Wuqinxi exercise on mild depression in college students and analyze the changes in hydrogen proton magnetic resonance spectra (H-MRS) in the prefrontal cortex and hippocampus after the exercise.

METHODSFifty-eight volunteer college students, including 30 with mild depression and 28 healthy students, were randomized into the intervention group and non-intervention group. The students in the intervention group were asked to practice health Qigong Wuqinxi training for 12 weeks and those in the non-intervention group did not engage in such training. For each subject, BECK Depression Self-reported questionnaire (BDI), Hamilton Depression rating scale (HAMD) score, and the metabolic parameters ofH-MRS in the prefrontal cortex and hippocampus were evaluated before and after the intervention.

RESULTSBefore the intervention, the scores of BDI and HAMD in the depression group were significantly higher than that in the control group (P<0.01), and were lowered obviously after the 12-week intervention (P<0.01). Compared with the control group,H-MRS in the depression group before intervention showed significantly increased NAA/Cr value in the left prefrontal cortex, Cho/Cr value in the bilateral hippocampus and the left frontal lobe, and Cho/Cr value of the left hippocampus and right frontal lobe (P<0.05) with significantly lowered NAA/Cho value in the bilateral prefrontal and Cho/NAA value in the right hippocampus (P<0.05). After 12 weeks of intervention, NAA/Cr value in the bilateral hippocampus and the NAA/Cho value in the right hippocampus were significantly lowered (P<0.05), and NAA/Cho value in the right prefrontal and Cho/NAA value in the right hippocampus were significantly increased (P<0.05) in the depression group. Before the intervention, Pearson correlation analysis showed that the scores of HAMD and BDI were positively correlated with Cho/Cr value in the hippocampus and NAA/Cr value in prefrontal lobe (P<0.01) and inversely with NAA/Cho in prefrontal lobe and Cho/NAA value in the hippocampus (P<0.05); after the intervention, the scores of HAMD and BDI were positively correlated with NAA/Cr value in the hippocampus and Cho/Cr value in the left hippocampus (P<0.05).

CONCLUSIONExercise of health Qigong Wuqinxi can reduce depression scale scores in patients with mild depression and improve the metabolic indexes (NAA/Cr and Cho/Cr values) in the prefrontal cortex and the hippocampus.

BACKGROUNDSleep disturbance is common in patients with emphysema. This study aimed to develop a novel model of sleep-related hypoxemia (SRH) in emphysema (SRHIE) with rats, and to explore the inflammatory status of SRHIE in lung, liver, pancreas, carotid artery and whole blood.

METHODSSeventy-five male Wistar rats were assigned to 5 groups with 15 per group according to the exposure conditions. The protocols varied with the degree of hypoxia exposure and severity of pre-existing emphysema caused by cigarette smoke exposure: (1) SRH control (SRHCtrl) group, sham smoke exposure (smoke exposure, exposed to smoke of 15 cigarettes twice everyday, 16 weeks) and SRH exposure (12.5% O2, 3 hours, SRH exposure, divide total hypoxia time (1.5 hours or 3 hours) into 4 periods evenly (22.5 minutes or 45 minutes) and distribute these hypoxia periods evenly into physiological sleep time of rats identified by electroencephalogram, week 9 to week 16); (2) Emphysema control (ECtrl) group, smoke exposure and sham SRH exposure (21% O2, 3 hours); (3) Short SRH in emphysema (SRHShort) group, smoke exposure and short SRH exposure (12.5% O2, 1.5 hours); (4) Mild SRH in emphysema (SRHMild) group, smoke exposure and mild SRH exposure (15% O2, 3 hours); (5) Standard SRH in emphysema (SRHStand) group, smoke exposure and SRH exposure (12.5% O2, 3 hours). ECtrl, SRHShort, SRHMild and SRHStand groups were groups with emphysematous rats. Two days before the end of exposure, 5 rats in each group were randomly selected for arterial blood gas analysis. In the rest 10 rats in each group, we obtained blood samples and bronchoalveolar lavage fluid (BALF) for routine tests. We also obtained tissue blocks of lung, liver, pancreas, and right carotid artery for pathologic scoring and measurements of liver oxidative stress (measuring hepatic oxidative stress enzymes, superoxide dismutase (SOD) activity, catalase (CAT) activity and malondialdehyde (MDA) concentration).

RESULTSEmphysematous groups had higher mean linear intercept (MLI) and mean alveolar number (MAN) values than SRHCtrl group. MLI values in SRHStand group were the highest (all P < 0.05). O2Sat in SRHStand rats when SRH exposure was (83.45 ± 1.76)%. Histological scores of lung, liver, pancreas and right carotid artery were higher in emphysematous groups than SRHCtrl group, and SRHStand group were the highest (all P < 0.05) (SOD and CAT values were lower and MDA values were higher in groups with emphysema than without and in SRHStand group than in ECtrl group (all P < 0.05)). MDA values were the highest in SRHStand group (all P < 0.05). Total cellular score in BALF and White blood cell (WBC) in whole blood were the highest in SRHStand group (all P < 0.05). Lymphocyte ratios were the highest in SRHStand group both in BALF and blood (all P < 0.05). Red blood cell (RBC) and hemoglobin in emphysematous groups were higher than that in SRHCtrl group, and SRHStand group were higher than ECtrl group (all P < 0.05).

CONCLUSIONSWith a proper novo model of SRHIE with Wistar rats, we have demonstrated SRH may aggravate the degree of emphysematous changes, polycythemia, oxidative stress and systematic inflammation. SRH and emphysema may have a synergistic action in causing systematic damages, and lymphocyte may be playing a central role in this process. Longer duration and more severe extent of SRHIE exposure also seem to result in more serious systematic damages. The mechanisms of all these concerned processes remain to be studied.

Objective:To Investigate the postoperative sexual function outcomes in patients with bladder cancer who underwent robot-assisted radical cystectomy (RARC)or laparoscopic radical cystectomy(LRC)followed by orthotopic neobladder reconstruction.Methods:We performed a retrospective review of 84 bladder cancer patients having undergone laparoscopic radical cystectomy(LRC)and robotic-assisted radical cystectomy(RARC)with≥21 IIEF-5 in our institution from Jan 2014 to Jan 2019. All of them were diagnosed as high grade urothelial carcinoma by biopsy or TURBT. Biopsy of the posterior urethra and bladder neck reveal negative result of tumor invasion. Their PSA level was less than 4.0 ng/ml with negative result of DRE. All patients undergone laparoscopic radical cystectomy and orthotopic neobladder reconstruction by one medical team. 45 patients underwent robotic assistant radical cystectomy(RARC group), and the rest of patients 39 were treated with laparoscopic radical cystectomy(LRC group). In RARC group, the mean age were 53 years old(ranging 50-67 years old)and clinical stage of the tumor was cT 1 in 10 patients, cT 2 in 21 patients and cT 3 in 14 patients. In the LRC group, the mean age were 56 years old(ranging52-65 years old) and the clinical staging of the tumors was 6 patients in cT 1, 23 patients in the cT 2 and 12 patients in the cT 3. The RARC group paid special attention to the protective function of the following surgical details: ①To detect the abdominal organs, reveal the pelvic cavity, observe the blood vessels and ureter, open the perinatal membrane next to the cross of the ureter, along the outer venous veins and closed-hole nerves around the standard or expand the pelvic lymph node cleaning. In this study, the patients who did not have obvious suspected lymph node metastasis were removed within the standard range of the pelvic lymph nodes on both sidesin order to protect the nerves at the pelvic floor as much as possible. ② With the robot 3rd arm lifting the bladder, the peritoneum was opened at the site of seminal vesicle and ampulla of vas deferent duct, which connected to the two sides with the open peritoneum. Along the vasectomy and the sac free, the denonvillier fasica was opened and exposing the back of the prostate. With the third arm pulling down, the umbilical ligament was observe. The peritoneal was opened to the retropubic space so that the prostate region was revealed. Continue to dissect the bladder front space until the pelvic fascia and the osteopathic prostate ligament are exposed. The Hem-o-1oks were used to ligate the bilateral bladder lateral ligaments. The bladder and prostate were removed in the fascia level. The NVB bundle on both sides was kept to the apex of prostate. The urethra was exposed and remove the catheter.With Hem-o-lok clamping, the urethra was dissected in the level of prostatic apex. The distal end of urethral tissue was sent to the rapid freeze pathology examination. In the procedure of prostate removing, parallel prostate fascia excision was considered and pubo-prostatic ligament could be preserved.③ Preserving the bilateral neurovascular bundle (NVB) and try to avoid the damage of NVB. Retaining the bladder lateral ligament neurovascular bundle. Retaining the1.2-1.5 cm urethra and surrounding continent control structure. The cold knife is advocated. Blood vessel clamp can be used to stop bleeding. We compared with operative time, bleeding amount, postoperative hospitalization, IIEF-5 scores and satisfaction of sexual between those groups. Results:All operations were successfully performed without conversion and serious surgical complications. The operative time in the RARC group and LRC group were [(313.5±31.9)min and (276.5±32.3)min, P>0.05] .The intraoperative amount of blood loss and postoperative hospitalization were [(190.1±44.1) ml and (212.3±39.2) ml, P>0.05], [(14.3±2.1) d and (15.2±3.0) d, P>0.05]. There was no significantly difference between the two groups. The median follow-up period of 84 patients was 18 months. The IIEF-5 score of the RARC group was higher than LRC group at 6 months(18.5±1.6 vs.10.6±1.3)and 12 months (18.6±2.4 vs.11.2±1.4) ( P<0.05). In addition, the satisfaction of sexual in the RARC group was relative better than LRC group (both P<0.05) at 6 months[44.4%(20/45)vs.25.6%(10/39)], and 12 months[51.1%(23/45) vs.28.2%(11/39)] post-operation. Conclusion:Robot-assisted radical cystectomy(RARC) and orthotopic neobladder reconstruction revealed relative better recovering in post-operative sexual function and improvements in patient quality of life.
