Wettability and seem assimilation regarding graphene oxide doped polymer bonded hydrogel.
In the other 11 patients (50%), α1 blocker was resumed because ofthe patient's request to resume the use of α1 blocker (Resumption group). The mean length ofdutasteride monotherapy was 4. 5 months (1-8 months) in the resumption group. Compared with the non-resumption group, IPSS total score and storage sub-score ofIPSS at the time of α1 blocker discontinuation were significantly higher in the resumption group. Based on the ROC curve, IPSS total score less then 16, IPSS voiding/storage symptom score less then 7, OABSS less then 7 and PV 54 ml or more at the time of α1 blocker discontinuation were predictors ofnon-resumption of α1 blocker. These results suggest that if LUTS is controlled by a long-term combination therapy ofdutasteride and α1 blocker and still PV is large enough, α1 blocker can be discontinued.Sixty eight patients had robot-assisted radical prostatectomy (RARP) from January 2016 to April 2017 with estimated blood loss of less than 500 ml. We compared the postoperative complication rates and the length of hospital stay between 34 of these patients who had pelvic drain placement (PD group), and the remaining 34 patients who had no drain placement (ND group). The approach was intraperitoneal in 25 patients in each group. The PD and ND groups were comparable for age (69.5 vs 70 yrs, P=0.459), clinical Gleason Score (6/7/≧8) 2/17/15 vs 3/8/23 (P=0.077), clinical stage (1c/2/3) 3/25/6 vs 1/25/8 (p=0. 539), operative time (311 vs 309 min, P=0.868), and estimated blood loss (p=0.166). The PD group had significantly higher median PSA level than the ND group (8.01 vs 6.25 ng/ml, P=0.023). Incidence of 30- day overall complications in the PD group (35 events) was lower than that in the ND group (38 events). All complications were classified as Clavien Dindo grade I. The postoperative hospital stay was 8 days in the PD group and 7 days in the ND group, showing no prolongation in the ND group. Pelvic drainage may be omitted after RARP without increasing postoperative complications or prolonging the hospital stay.The current studies show that tumor microenvironment of malignant tumor plays critical roles in the tumor progression. The stroma is the main component of tumor microenvironment and the tumor-stroma ratio (TSR) may reflect the relationship of tumor and tumor microenvironment, which has drawn increasing attention from the field of clinical research of cancer.With poor survival,pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease characterized by an intense fibrotic stromal response and the clinical researches related with TSR in PDAC are more significant for patients management compared with that in other tumors.The evaluation methods for TSR are not inconsistent in different studies. But the evaluation result of TSR in pathological method based on whole-mount slide image agrees with that in radiological method, so as the prognosis prediction, that TSR>1 indicated poor prognosis.So TSR can be a stratification marker for patients with PDAC to optimize the tumor stage system used currently. The radiological evaluation before surgery widen the clinical application of TSR in the precise and individual management of patients with PDAC.The comparison for evaluation methods of TSR and the relationship of TSR and prognosis are still needed thorough investigation in ongoing studies with a larger number of patients in multiple centers.Esophagogastric variceal bleeding (EVB) is the most dangerous complication of cirrhotic portal hypertension.With the continuous emergence of research findings on EVB, multiple disciplinary team, including internal medicine department, surgery department, intervention therapy department, radiology department, has become a new mode for the prevention and treatment of EVB. this website This article first reviewed the classification of esophageal varices and gastric varices, and then reviewed the recent research findings of EVB from three aspects primary prophylaxis, active variceal bleeding treatment, and secondary prophylaxis.The aim was to provide new ideas for the individualized prevention and treatment of EVB.Objective To evaluate the early results of pulmonary autograft mitral valve replacement (Ross Ⅱ procedure) in infants with intractable congenital mitral valve lesions. Methods Between August 2018 and September 2019, 6 infants underwent mitral valve replacement with a pulmonary autograft in Department of Cardiovascular Surgery, Guangzhou Women and Children's Medical Center. There were 2 males and 4 females.The age at surgery ranged from 50 days to 1 year old.Preoperative diagnoses included severe to critic mitral valve insuffiency in all patients, moderate mitral valve stenosis in 3 patients, and mitral valve prolapse in one. When the pulmonary autograft was harvested, a cuff of bovine or autologous pericardium was sewn onto the proximal (infundibular) end of the autograft ( "top-hat" configuration). The distal (pulmonary) end of the autograft was secured to the mitral annulus.At the level of the left atrial free wall, the pericardial cuff was progressively tailored and sewn onto the atrial wall to remain away for young infants with intractable congenital mitral valve lesions.Objective To examine the safety and clinical efficacy of ultrasound-guided irreversible electroporation (IRE) using the open surgery approach, after induction chemotherapy, in the treatment of locally advanced pancreatic cancer (LAPC) . Methods The data of 64 LAPC patients who underwent ultrasound-guided IRE using the open surgery approach after induction chemotherapy at Department of Pancreatobiliary Surgery, Sun Yat-sen University Cancer Center from August 2015 to March 2019 were retrospectively analyzed. The study comprised of 30 males and 34 females, with median age of 58.5 years old (range 34 to 87 years old) , were included in this study.The tumor was located in the pancreatic head and body/tail in 30 and 34 patients, respectively.The largest recorded tumor size was 6.1 cm (≤4.0 cm n=35; >4.0 cm n=29) .To create an electric field around the tumor, Two to six probes were parallelly inserted into each patient's tumor, based on the size of the tumor, at a distance of 2 cm apart through the transverse mesoche entire cohort was 20.3% and all were classified as grade B.Of them, pancreatic fistula, incisional infection, and upper gastrointestinal hemorrhage were observed in 7, 4, and 2 cases, respectively.The rate of complications for patients in the primary and secondary treatment groups were significantly different (10/15 vs. link2 6.1%) , respectively (χ(2)=26.01, P less then 0.01) .Further, two deaths were observed after IRE in the primary treatment group, while none was observed in the secondary treatment group. Conclusions Ultrasound-guided IRE using the open surgery approach after induction chemotherapy is found to be safe and effective in treating patients with LAPC.However, these findings should be validated in prospective randomized trials before wide clinical application.Objective To examine the surgical approach, practical cognition as well as clinical effect of the orthotopic resection for laparoscopic pancreatoduodenectomy(OLPD). Methods From March 2019 to December 2019, 32 cases were treated with laparoscopic pancreatoduodenectomy (LPD) in a novel approach without mobilization of pancreatoduodenum in Pancreas Center of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine.There were 16 male patients and 16 female patients.The mean age was (64.8±9.5) years old.Body mass index was 14.9 to 31.0 kg/m(2).All patients were diagnosed as ampullary or pancreatic head tumors and were not unresectable cases.In the surgical strategy, Kocher's dissociation, turning and pulling of the pancreaticoduodenal region, was not performed first.Anatomy in situ, separation of vessels which enter and exit from pancreas, separation of lymphatics and isolation of tumors were carried out in priority through the combined middle and left posterior approaches.Finally, the pancreatiive better treatments and results.Objective To examine the value of serum protein induced by vitamin K absence or antagonist-Ⅱ (PIVKA-Ⅱ) detection in the early diagnosis and surveillance of hepatocellular carcinoma (HCC). Methods The clinical data of 215 patients with HCC admitted to Department of Hepatobiliary-Pancreatic Surgery of China-Japan Union Hospital of Jilin University from October 2017 to May 2018 were analyzed retrospectively. There were 172 males and 43 females, aged of (59.0±9.3) years old (range 34 to 86 years old). In addition, there were 85 non HCC patients were enrolled in the control group, 42 males and 43 females, aged (54.2±11.3) years old (range 22 to 80 years old). The blood sample of 3 ml was drawn from the elbow vein at 6∶00 am on the next day of admission, and then was kept in low temperature away from light, and sent for PIVKA-Ⅱ detection on the same day. The positive value of AFP was ≥20 μg/L and PIVKA-Ⅱ was ≥32 AU/L. The data were analyzed statistically by χ(2) test, t test or rank sum test. The correlation betweeA-Ⅱ detection was significantly sensitive than AFP in the earlier stage of HCC. Combined detection of PIVKA-Ⅱ and AFP can effectively improve the diagnostic rate of HCC in all stages. The significant elevation of PIVKA-Ⅱ is also helpful to determine the tumor aggressiveness, vascular invasion and prognosis of HCC patients.Objective To examine the safety and effectiveness of ultrasound-guided percutaneous radiofrequency ablation in the treatment of liver malignant tumor under subcardiac. Methods The clinical data of 26 patients (31 tumors) with subcardiac liver malignant tumors who underwent ultrasound-guided percutaneous radiofrequency ablation from January 2017 to October 2019 at the Affiliated Tumor Hospital of Zhengzhou University were retrospectively analyzed. There were 21 males and 5 females. The age was 55 years old (range 40 to 77 years old) .There were 14 cases of primary liver cancer and 12 cases of metastatic liver cancer. The maximum diameter of tumor was (2.3±1.0) cm (range 1.0 to 4.2 cm) .According to the maximum diameter of the tumor, 1∶1 match was made between 27 non-subcardiac patients admitted at the same time and a total of 36 liver malignant tumors. subcardiac tumor is defined as tumor ≤1 cm from pericardium in sagittal or coronal imaging. The ablation effect and complications were recorded, and the one-timn tumor margin and pericardium ≤5 mm was an independent risk factor affecting radiofrequency ablation (OR=0.020, 95%CI 0.001 to 0.454, P=0.014) . link3 Conclusions Ultrasound-guided percutaneous radiofrequency ablation can safely and effectively treat liver malignant tumor under subcardiac. When there is a tumor near the patient's heart (the distance between the edge of the tumor and pericardium is ≤5 mm) , special attention should be paid to formulate a detailed and reasonable ablation plan to minimize tumor residue.Objective To investigate the value of Gd-EOB-DTPA-enhanced MRI in evaluating liver function and predicting the risk of post-hepatoectomy liver failure in patients with major resection of liver cancer. Methods A total number of 212 patients were included from June 2016 to June 2019 at Department of General Surgery, Peking University Third Hospital with a retrospectively collected data.All patients underwent Gd-EOB-DTPA-enhanced MRI for diagnosis and preoperative evaluation of liver function.There were 135 males and 77 females, with age of (63.1±10.3) years old (range 18 to 86 years old) . Relative enhancement ratio (RER) of the region of interest on Gd-EOB-DTPA-enhanced MRI was acquired by two independent researcher and then conducted the comparison of RER among the patients with or without post-hepatoectomy liver failure (PHLF) .Preoperative evaluation demonstrated that 141 cases infected by hepatitis virus, 128 cases with hepatitis B alone and 11 cases with hepatitis C alone, 2 cases had both of hepatitis B and C, and all patients were grade A judged by Child-Pugh score.
