Objective To evaluate the efficacy and safety of paclitaxel drug-coated balloons (DCB)in treating acute coronary syndrome in patients with high bleeding risk.Methods A total of 35 inpatients with acute coronary syndrome and high bleeding risk who were treated in our hospital from March 2017 to December 2017 were retrospectively analyzed.The patients were divided into the control group (n=20) treated with normal balloon dilatation and the experimental group (n =15) treated with DCB treatment.The age,major cardiac adverse events(MACE)within 3 months,fatal hemorrhage events,all-cause mortality,attributable mortality,target lesion revascularization rate(TLR),coronary artery stenosis degree before intervention,and coronary artery stenosis degree at once and 3 months after surgery,were used for comparison and for statistical analysis between the control and the experimental group.Results There were no significant differences between the two groups in the indexes as the followings:MACE within 3 months after surgery(25.0％ vs.6.7％,x2 =2.03,P =0.15),fatal hemorrhage events (10.0 ％ vs.6.7 ％,x2 =0.12,P =0.727),all-cause mortality (20.0％ vs.6.7％,x2 =1.24,P =0.27),attributable mortality(10.0％ vs.0.0％,x2 =1.59,P=0.21),TLR(14.3％ vs.0％,x2 =3.08,P =0.08).However,the incidence of fatal hemorrhage and MACE,all-cause mortality,attributable mortality and TLR were relative low in the experimental group (P＞0.05).Conclusions Drug-coated balloon treatment is safe and effective in treating acute coronary syndrome in patients with high bleeding risk.

Objective:To assess the prognostic value of modified Charlson comorbidity index (mCCI) combined with serum albumin for long-term prognosis in peritoneal dialysis (PD) patients.Methods:From January 1, 2007 to June 30, 2015, patients who started PD in Nanjing Drum Tower Hospital were enrolled in this retrospective cohort study. Clinical data including gender, age, underlying diseases, laboratory examination and prognosis were collected. The mCCI at the beginning of PD was calculated. Whether the duration of PD exceeded 5 years was used as an indicator to evaluate the prognosis. The patients were divided into≥5 years group and<5 years group according to the duration of PD, and the data were compared between the two groups. Cox regression model was constructed to analyze the influencing factors of all-cause death in PD patients. Multivariate logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the predictive value of mCCI and serum albumin levels on whether patients could maintain long-term PD.Results:Of the 183 patients included [males 106(57.9%), females 77(42.1%); (53.35±16.50) years old; 162 cases (88.5%) with hypertension, 55 cases (30.1%) with diabetes], 97 cases had PD duration for ≥5 years and 86 cases less than 5 years. The overall 5-year technical survival rate was 65.1%. At the beginning of PD, compared with the dialysis age≥5 years group, the patients in the dialysis age less than 5 years group had older age, higher mCCI, lower serum albumin level, and higher C-reactive protein (CRP) level (all P<0.05), but there were no significant differences in gender, education level, electrolyte, mean arterial pressure, high densitv lipoprotein (HDL), low-density lipoprotein (LDL) and PD adequacy index between the two groups (all P>0.05). Multivariate logistic regression analysis showed that increased age ( OR=1.022, 95% CI 1.000-1.043, P=0.046), increased mCCI ( OR=1.620, 95% CI 1.300-2.018, P<0.001) and decreased serum albumin ( OR=0.807, 95% CI 0.730-0.893, P<0.001) were independent predictors for the duration of PD<5 years. ROC curve analysis showed that the area under ROC curves ( AUC) of mCCI, serum albumin level and combined prediction probability of the two for the duration of PD<5 years were 0.647(95% CI 0.568-0.727), 0.655(95% CI 0.577-0.734), and 0.767(95% CI 0.700-0.835), respectively, indicating that the accuracy of combined parameters to predict survival outcome was higher than that of any single parameter. Multivariate Cox analysis showed that increased age ( HR=1.073, 95% CI 1.046-1.100, P<0.001), increased mCCI ( HR=1.198, 95% CI 1.044-1.375, P=0.010) and decreased serum albumin ( HR=0.904, 95% CI 0.843-0.969, P=0.004) were independent influencing factors for all-cause death in PD patients. Conclusions:Old age, high mCCI and low serum albumin level are influencing factors for dialysis age<5 years and all-cause death in PD patients. mCCI combined with serum albumin level can improve the accuracy of predicting the long-term dialysis in PD patients.

Objective:To investigate the correlation of peripheral blood neutrophil-lymphocyte ratio(NLR)and platelet parameters with the prognosis of elderly patients with cerebral hemorrhage.Methods:Clinical data of 80 patients with cerebral hemorrhage admitted to the neurosurgery department of our hospital from January 2017 to July 2019 were retrospectively analyzed.Based on modified Rankin scale scores, they were classified into the good prognosis group(n=49, with modified Rankin scale scores <3 points)and the poor prognosis group(n=31, with modified Rankin scale scores between 3-6 points). General demographic data and results on laboratory indexes including platelet(PLT), platelet distribution width(PDW), mean platelet volume(MPV), absolute lymphocyte count(ALC)and absolute neutrophil count(ANC)were compared between the two groups.Logistic regression analysis was performed to examine the effects of platelet parameters and NLR on the prognosis of elderly patients with cerebral hemorrhage.Results:NLR, PDW and MPV were higher and PLT was lower in the poor prognosis group than in the good prognosis group[(8.89±1.95) vs. (3.13±0.21), (16.75±4.32) % vs.(12.89±2.71) %, (14.82±3.52) % vs. (10.78±1.62) %, (0.37±0.20) % vs.(0.62±0.33) %, t=20.564, 4.918, 6.969 and 4.918, all P<0.001)]. Logistic regression analysis showed that increased levels of NLR, PDW and MPV and decreased levels of PLT were influencing factors for poor prognosis in elderly patients with cerebral hemorrhage( OR=2.759, 2.606, 1.756 and 0.095, all P<0.001). Conclusions:NLR, PDW, MPV and PLT are closely correlated with the prognosis of elderly patients with cerebral hemorrhage and may be used as indexes for prognosis evaluation in these patients.

Objective:To investigate the application value of TRIANGLE operation in radical resection of pancreatic cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 30 patients with pancreatic cancer who underwent TRIANGLE operation in the First Affiliated Hospital of Nanjing Medical University from March 2020 to July 2020 were collected. There were 18 females and 12 males, aged from 41 to 79 years, with a median age of 65 years. After assessment of the resectability and dissection of the hepatoduodenal ligament, the superior mesenteric artery, celiac axis, common hepatic artery, portal vein and superior mesenteric vein of patients were exposed. According to the location of tumor, patients were performed pancreaticoduodenectomy, distal pancreatectomy or total pancreatectomy combined with dissection of putatively tumor-infiltrated lymphatic and neural tissue from the triangular space. During the TRIANGLE operation, it required to at least finish the skeletonization of right semi-circumference of the superior mesenteric artery and celiac axis in cases of pancreatico-duodenectomy, whereas the left semi-circumference in cases of distal pancreatectomy. In principle, both of the superior mesenteric artery and celiac axis were circumferentially skeletonized for cases of total pancreatectomy. Lymphatic, neural and fibrous tissues between the superior mesenteric artery and the celiac artery were completely dissected in all patients. Observation indicators: (1) surgical conditions and postoperative histopathological examination; (2) postoperative recovery situations; (3) follow-up. Regular follow-up was conducted by telephone interview or outpatient examinations to understand tumor recurrence and metastasis of patients up to January 2021. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, Fisher exact probability method was used for comparison between groups. Results:(1) Surgical conditions and postoperative histopathological examination: all patients underwent open operation, including 21 cases of pancreaticoduodenec-tomy, 6 cases of distal pancreatectomy, 2 cases of total pancreatectomy, 1 case of mid-segment preserving pancreatectomy. There were 16 cases combined with portal vein-superior mesenteric vein resection and 3 cases combined with left adrenal resection. For the dissection area of superior mesenteric artery-celiac axis, one cycle was conducted in 5 of 30 patients, one and a quarter cycle in 8 patients, one and a half cycle in 8 patients, one and three quarters?two cycles in 9 patients. There were 16 cases with left gastric vein dissection and 14 cases with left gastric vein preservation. The operative time of 30 patients was 287 minutes (range, 165?495 minutes) and the volume of intraoperative blood loss was 275 mL(range, 50?800 mL). Nine patients received intraoperative transfusion of red blood cells or frozen plasma. Postoperative histopathological examination showed that the tumor diameter was 3.4 cm (range, 1.2?7.3 cm), the number of harvested lymph nodes was 20 (range, 9?35), the number of positive lymph nodes was 2 (0?19). Of the 30 patients,20 cases had moderately differentiated tumor and 10 cases had poorly differentiated tumor. R 0 resection was achieved in 9 patients, 1 mm R 1 resection in 17 patients, and R 1 resection in 4 patients. Postoperative pathological T stages: 3 of 30 patents were in stage T1, 18 cases were in stage T2, 5 cases were in stage T3, and 4 cases were in stage T4. Postoperative pathological N stages: 9 of 30 patents were in stage N0, 13 cases were in stage N1, and 8 cases were in stage N2. Postoperative pathological TNM stages: 2 of 30 patents were in stage Ⅰa, 2 cases were in stage Ⅰb, 3 case were in stage Ⅱa, 11 cases were in stage Ⅱb, 12 cases were in stage Ⅲ. (2) Postoperative recovery situations: 20 of 30 patients had postoperative complications, including 6 cases of Clavien-Dindo grade I complications, 9 cases of grade Ⅱ complications, 3 cases of grade Ⅲa complications, 2 cases of grade V complications. The incidence of postoperative diarrhea was 0 in cases with one cycle dissection of tissues around superior mesenteric artery-celiac axis, 1/8 in cases with one and a quarter cycle dissection, 4/8 in cases with one and a half cycle dissection, 9/9 in cases in with one and three quarters-two cycles dissection, showing a significant difference between the four groups ( P<0.05). The incidence of delayed gastric emptying was 5/16 in patients with left gastric vein dissection, versus 1/14 in patients with left gastric vein preservation, showing no significant difference between the two groups ( P>0.05). Nineteen of 30 patients received adjuvant chemotherapy.Twenty-eight of 30 patients were successfully discharged from hospital, with the duration of postoperative hospital stay of 15 days(range, 8?68 days) and the rest of 2 patients died. Three patients had unplanned readmission within postoperative 90 days. (3) Follow-up: all the 28 patients discharged from hospital were followed up for 1.0?9.0 months, with the median follow-up time of 6.5 months. During the follow-up, one patient with locally advanced pancreatic cancer had local recurrence, 9 patients had liver metastasis (including 4 cases with resectable pancreatic cancer, 4 cases with borderline resectable pancreatic cancer, 1 case with borderline resectable pancreatic cancer), and 1 patient with borderline resectable pancreatic cancer had peritoneal metastasis. The rest of 17 patients survived without tumor recurrence. Conclusions:TRIANGLE operation in the radical resection of pancreatic cancer has high radicality and low postoperative local recurrence, but a slightly high morbidity and mortality rate. Its long-term efficacy needs to be further evaluated. It is recommend that this procedure should be performed for selected patients after neoadjuvant chemotherapy in high-volume pancreatic surgery centers.

Radical resection remains essential for prolonging survival and increasing the possibility of cure in pancreatic cancer.However,few patients are resectable at the time of diagnosis,with a portion of patients presenting with portal and superior mesenteric vein invasion and regarded as resectable or locally advanced disease.Venous resection in pancreatectomy enables achievement of tumor-free margins in patients with venous invasion.This review provides an overview of preoperative evaluation,resection and reconstruction types,vascular grafts selection,morbidity,mortality and survival in radical pancreatectomy with portal and superior mesenteric vein resection.

Objective: To evaluate risk factors for delayed gastric emptying(DGE)following pancreaticoduodenectomy(PD). Methods: There were 492 consecutive patients who underwent PD in Pancreas Center, the First Affiliated Hospital with Nanjing Medical University between January 2012 and December 2014 were identified from a prospective database.There were 315 male and 177 female patients with a median age of 60.5 years.Univariate and multivariate analyses were performed to investigate the independent risk factors for clinically relevant DGE(CR-DGE). Results: The overall incidence of DGE was 29.5%, with Grade B and C occurring at 4.3% and 5.9%, respectively.In multivariate analysis, pancreatic duct diameter less than 3 mm(OR=1.888, P=0.042), pylorus-preserving pancreaticoduodenectomy(OR=2.627, P=0.005) and clinically relevant postoperative pancreatic fistula(OR=2.740, P=0.007) were independently associated with CR-DGE.Other main complications such as postoperative pancreatic fistula, pyoperitoneum, intraabdominal infection were also associated with the severity of DGE(χ²=21.360, 14.422, 14.378; P=0.011, 0.002, 0.002). DGE patients had a significantly prolonged postoperative length of stay(31(24-41)d vs. 13(11-17)d) and increased medical cost((122 367.5±66 068.3)yuan vs. (78 200.7±27 043.9)yuan)(both P<0.01). Conclusions Small pancreatic duct, underwent pylorus-preserving pancreaticoduodenectomy and suffered postoperative pancreatic fistula might indicate a high risk of CR-DGE.
