Objective To investigate the distribution and severity of cerebral artery stenosis and the prognosis in elderly patients with acute cerebral infarction using digital subtraction angiography (DSA). Methods The 432 elderly patients with acute cerebral ischemia infarction underwent DSA,and they were divided into two groups: elderly group (n= 320) and non-elderly group (n= 112). The characteristics of distribution and severity of cerebral artery stenosis, the relationship between artery stenosis and relative risk factors, and the prognosis of acute cerebral infarction were analyzed.Results In elderly group, 270 cases (84.3%) had intra- and extra- cranial artery stenosis, of which 98 patients (30.6%) with pure extracranial arterial stenosis, 132 patients (41.3%) with combined extra- and intra-cranial artery stenosis. They were both significantly higher than the corresponding data in non-elderly group [23 cases (20.5%) and 28 cases (25%), P＜0.05 and 0.01]. The prevalences of moderate and severe cerebral artery stenosises were higher in elderly group than in nonelderly group [224 locations (52.1%) vs. 51 locations (40.8%), P＜0. 05]. The number of patients with previous history of cerebrovascular disease was much more and the prognosis was much worse in elderly group than in non-elderly group (both P＜0.05), Conclusions The elderly patients with cerebral infarction have severer cerebral artery stenosis, increased proportion of multivessel disease and poor prognosis. So it is very important to take aggressive treatment as soon as possible, and to make secondary prevention and effective rehabilitation so as to improve their prognosis.

Objective To assess the effect of low-dose cytarabine and aclarubicin in combination with gran-ulocyte colony-stimulating factor (G-CSF) protocol (CAG) in patients with acute myeloid leukemia (AML),and to understand the potential factors affecting the outcome of CAG induction therapy, therefore to find the optimum pa-tients for CAG therapy. Methods Twenty-one AML patients were enrolled in the current study. All patients were treated with CAG regimen including cytarabine (10 mg/m~2, subcutaneously, every 12 h, days 1 - 14), lacinomycin (5～7 mg/m~2,intravenously,every day, days 1 -8) ,and G-CSF (200 μg/m~2,subcutaneously, every day,12 h be-fore Ara-C was given) priming. Results The overall complete remission (CR) rate of the 21 AML patients was 66.7% (14/21). The CR rates was 87.5% (7/8) in patients older than 60 yrs,60.0% (9/15) in the refractory or relapsed patients,83.3% (5/6) in the MDS transformed AML patients. The CR rates for patients with hyperprolif-erative BM and median to poor proliferative BM were 33.3% and 91.7% ,respectively(P =0.009). The median o-verall survival (OS) time of the 21 AML patients was 450 days. Two-year survival rate estimated by Kaplan-Meier Method was 30.6%. The overall median disease free survival (DFS) was 165 days. The median OS time for those refractory or relapsed was 435 days. The median OS time for those with poor cytogenetic state or standard or good cytogenetic state was 140 days and 620 days, respectively (P = 0.001). The median OS time for patients with hyperproliferative BM and median to poor proliferative BM was 321 days and 620 days, respectively (P = 0.05). The median recovery time of granulocytes above 1.0×10~9/L was 8 days. The median duration of fever was 3.5 days. The rate of infections exceeding WHO grade Ⅱ was 42.9%. No early death occurred. Conclusions The CAG induction therapy may have a higher CR rate in patients with refractory or relapsed AML, elderly AML and secondary AML from MDS transformation, and extend the median overall survival time in refractory or relapsed patients. CAG therapy can not improve the outcome of patients whose BM was in high grade proliferation state or whose cytogenetic state was poor. CAG therapy can shorten the duration of agranulocytosis and decrease the inci-dence of serious infection. Therefore, CAG therapy is worth recommending to patients who can not endure the rou-tine intensive chemotherapy.

Objective To analyze the factors and prognosis of graft recovery after donation after citizens death (DCD) donor renal transplantation.Methods A retrospective analysis of 67 cases of DCD renal transplantation from August 2012 to September 2015 in our hospital was carried out.According to the stability of renal function after operation,the patients were divided into group A (51cases) with stable renal function,and 16 cases in group B (delayed graft function after operation).The clinical data of two groups including age,gender,cause of death,warm ischemia time,type of dialysis,and application of norepinephrine before operation were collected and analyzed.The related factors of graft function recovery were analyzed.Logistic regression analysis was used to analyze the risk factors of graft functional recovery after operation.The 3-month,6-month,1-year and 18-month survival rate after operation in the two groups was compared.Results The causes of death,the time of ischemia,the type of dialysis before operation,the application of norepinephrine before operation,infants and young donors were related factors of graft function recovery (P ＜ 0.05).Logistic regression analysis showed that cerebral hemorrhage death donor,the long thermal ischemia time,the preoperative hemodialysis and the application of norepinephrine before operation were the risk factors of delayed graft function recovery (P＜0.05).The 3-month,6-month,1-year and 18-month survival rate after operation in group A was higher than that in group B,with the difference being statistically significant (P＜0.05).Conclusion Cerebral hemorrhage death donor,the long thermal ischemia time,the preoperative hemodialysis and the application of norepinephrine before operation were the independent risk factors of delayed graft function recovery.And the prognosis of patients with delayed graft function was poor.Clinical risk should be eliminated or reduced in clinical practice,which can effectively prevent the delayed graft function and further improve the prognosis of the patients.

BACKGROUNDAccording to the report of the 11th World Conference on Lung Cancer, lung cancer is the leading cause of cancer related death. So there is important clinical significance to monitor the patients with lung cancer through different ways. The aim of this study is to investigate the clinical significance of multiple tumor marker protein chip in monitoring the recurrence, progression and metastasis of lung cancer.

METHODSForty-four patients were selected, who were detected at least 4 times with tumor mar-ker protein chip. Based on efficacy and status, patients were classified as six grades. Correlation of expression level of each tumor marker with grade of efficacy and status was analyzed. And the discriminant functions for recurrence, progression and metastasis of lung cancer were established.

RESULTSGrade of efficacy and status was closely related to CA199, CEA, CA242, AFP and CA125 in adenocarcinoma (AC), to CA125 in squamous cell carcinoma (SqCa), and to CA199 and CA125 in small cell lung cancer (SCLC). Based on the discriminant functions, accuracy rate of efficacy and status judgement was 89.4%, 80.4%, 78.3% and 66.7% for female AC, male AC, SqCa and SCLC respectively.

CONCLUSIONSThere is important clinical significance of multiple tumor marker protein chip in monitoring the recurrence, progression and metastasis of lung cancer (especially adenocarcinoma).

Objective: To investigate the therapeutic effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with FLAG sequential busulfan/cyclophosphamide(Bu/Cy) conditioning regimen for refractory/relapsed acute myeloid leukemia. Methods: From February 2012 to June 2017, 21 patients with refractory/relapsed acute myeloid leukemia underwent allo-HSCT with FLAG sequential Bu/Cy conditioning regimen. Transplantation-related complications and clinical outcome were retrospectively analyzed. Results: After conditioning, no hepatic veno-occlusive disease (VOD) and grade Ⅲ hemorrhagic cystitis occurred. 76.2% (16/21) patients had fever with 4 septicemia. One patient died of septic shock before engraftment. Twenty patients achieved neutrophil engraftment with a median time of 13 days (range, 10 to 21 days). Seventeen patients achieved platelet engraftment with a median time of 18 days (range, 9 to 25 days). The cumulative incidence of acute graft-versus-host disease (aGVHD) was 39.5%, and 3 patients developed grade Ⅲ-Ⅳ aGVHD. Of 19 patients who survived more than 100 days after transplantation, 4 had local chronic graft-versus-host disease (cGVHD). Of 21 patients, the median survival time was 15 months (range, 0.5 to 67 months) post-transplantation. Transplantation-related mortality rate was 28.7%. Leukemia relapse occurred in 4 patients with a median time of 4 months (range, 3 to 8 months) after transplantation. The cumulative relapse rate at 1 year was 21.4%. The 1-year and 3-year overall survival (OS) rates were 60.7% and 54.9% respectively. Log-rank analysis revealed that bone marrow blasts ≥ 20% or extramedullary leukemia before transplantation, poor platelet engraftment and grade Ⅲ-Ⅳ aGVHD were significantly related to shortened OS (P<0.05). Conclusions Allo-HSCT with FLAG sequential Bu/Cy conditioning regimen in patients with refractory/relapsed myeloid leukemia has acceptable transplantation-related risk and relapse rate. The 1-year and 3-year OS rates are comparable with those in remission patients.

Objective To investigate the safety and feasibility of the modified terminal cannula ileostomy in laparoscopic anus-preserving operation of low rectal cancer (RC).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 15 patients who underwent laparoscopic radical resection of RC + terminal cannula ileostomy in the Subei People's Hospital of Jiangsu Province between September 2016 and June 2017 were collected.The patients underwent laparoscopic low anterior resection of RC,intra-abdominal sigmoid colon-rectum end-to-end anastomosis after extracting tumor specimens,and terminal cannula ileostomy in vitro.Observation indicators:(1) intraoperative situations:operation time,time of cannula ileostomy,volume of intraoperative blood loss,number of lymph node dissected,surgical margin;(2) postoperative situations:time to initial anal exsufflation,recovery time of defecation,time of tube removal,closing time of stoma,postoperative complications,duration of hospital stay;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the anastomotic leakage-related complications up to December 2017.Measurement data with normal distribution were represented as (x)±s.Results (1) Intraoperative situations:all the 15 patients underwent successful laparoscopic radical resection of RC + terminal cannula ileostomy,without conversion to open surgery and death.The operation time,time of cannula ileostomy,volume of intraoperative blood loss and number of lymph node dissected were respectively (170 ± 34) minutes,(23 ± 4) minutes,(59 ± 27)mL and (13 ± 5) per case.No residual cancer cells were found in resection margins.(2) Postoperative situations:time to initial anal exsufflation and recovery time of defecation in 15 patients were respectively (6± 1) days and (7 ± 1) days.The stoma was automatically closed after tube removal,and time of tube removal and closing time of stoma after tube removal were respectively (23 ± 2) days and (3 ± 1) days.The incidence of postoperative complications was 1/15.One patient with catheterization-related complications was improved by strengthening dressing and antibiotic use,and the stoma was healed at 8 days after tube removal.There was no anastomotic leakage-related complications and death.The duration of hospital stay was (15±3) days.(3) Followup situations:all the 15 patients were followed up for 6-12 months.During the follow-up,there were no anastomotic leakage-related complications and death.Conclusion The modifyied terminal cannula ileostomy is safe and feasible,and is also an ideal surgical method for preventing anastomotic leakage in the laparoscopic anuspreserving operation of low RC.

Objective: Remuzzi scoring system is utilized for assessing the degree of renal tissue damage in donors with hypertensive cerebral hemorrhage and donors with brain trauma after cardiac death. To explore the prognosis of hypertensive cerebral hemorrhage donor kidney in renal transplant recipients. Methods: The kidney donated by DCD between January 1, 2016 to June 1, 2018 were retrospectively reviewed. Pathological biopsy was performed before transplantation and hematoxylin-eosin (HE) staining after sectioning. The degree of renal tissue lesions was evaluated by Remuzzi scoring system. According to the source of donor kidney, they were divided into two groups of donors with heart failure due to hypertensive cerebral hemorrhage (HCH) and those with brain trauma (BT). Both groups of donor kidneys were preserved by low-temperature machine perfusion. The immunosuppressive regimen was identical in both groups. The prognosis of two groups was compared by serum creatinine (Scr) at Month 1/6/12 post-operation and cumulative graft survival rate over a follow-up period of 12-36 months. Results: The renal Remuzzi score of HCH donors was significantly higher than that of BT donors. The maximal creatinine clearance rate was significantly lower than that of BT donors [(86.8±27.8) vs (115.4±23.2) ml/min, P<0.05]. At 1/6/12 months post-transplantation, serum creatinine levels were (76.1±18.5), (72.4±16.2) and (71.4±16.8) μmol/L in BT group and (160.3±33.4), (154.3±32.6) and (146.4±29.1) μmol/L in HCH group. The SCr in BT group at 1/6/12 months was lower than that in HCH group (P<0.05). Kaplan-meier analysis showed no significant inter-group difference in graft survival between two groups over a follow-up period of 12 to 36 months (Log-Rank test, P=0.485). Conclusions No significant difference exists in short-term survival rate of kidneys from HCH and BT donors. The recipients of HCH donor's kidney have higher serum creatinine levels than those of BT donors. Selective use of kidney transplants in patients with cardiac death caused by HCH may greatly reduce the waste of donor kidney and improve the quality-of-life of patients with end-stage renal disease.

Objective To determine the influence of abiraterone acetate (AA) on neuroendocrine differentiation (NED) in metastatic castration-resistant prostate cancer (mCRPC) and the prognostic predicting value of the serum NED markers in mCRPC patients treated with AA.Methods We conducted an analysis in 115 chemotherapy-naive mCRPC patients who were treated with chemotherapy in Renji hospital from 2013 to 2017.The median age was 70,ranged from 65 to 76 years old.The median CgA,NSE and PSA levels were 101.1 ng/ml (78.5-150.0 ng/ml),13.4 ng/ml (10.5-17.6 ng/ml) and 38.8 ng/ml (11.2-123.2 ng/ml),respectively.Among them,48 cases were classified as the group without AA treatment.The other 67 cases were classified as group after AA failure.In group without AA treatment,the median CgA,NSE and PSA levels were 109.1 ng/ml(80-151.5 ng/ml);13.8 ng/ml(10.8-18.2 ng/ml) and 39.2 ng/ml (8.6-200 ng/ml),respectively.In group after AA failure,the median CgA,NSE and PSA levels were 105.4 ng/ml(78.8-175.5 ng/ml),13.8 ng/ml(10.8-17.6 ng/ml) and 39.0 ng/ml(8.4-219.8 ng/ml),respectively.In the group with serial evaluation of NED markers during AA treatment,the median serum CgA,NSE levels at baseline were 115.9 ng/ml(90.1-201.5 ng/ml),13.3 ng/ml (10.4-18.1 ng/ml),respectively.The endpoints were PSA PFS(progression-free survival) and radiographic PFS (rPFS).Results In 34 patients with serial evaluation,serum NED markers level in 19 patients increased after the failure of AA treatment.Median serum CgA and NSE levels were 115.9 ng/ml(90.1-201.5 ng/ml)and 13.25 ng/ml (10.37-18.14 ng/ml) at baseline.Median serum CgA and NSE levels were 129.6ng/ml (75.5-230.5 ng/ml) and 14.7 ng/ml (11.8-19.1 ng/ml) after 6 months treatment,respectively.The median serum CgA and NSE levels were 130.4 ng/ml (95.7-205.7 ng/ml) and 15.2 ng/ml(12.4-18.7 ng/ml) at the time of failure of AA treatment,respectively.There was no significant difference of NED markers between baseline and failure of AA treatment (P =0.243).In logistic univariate analysis,AA treatment and its duration were not independent factors influencing NED(P =0.30;P =0.52).Compared with the NED markers elevation group in the first 6 months of AA treatment and baseline supranormal NED markers group,the NED markers decline group(PSA PFS(17.1 vs.10.4 months,P ＜ 0.001) and rPFS (17.0 vs.10.4 months,P =0.003)) and baseline normal NED markers group(PSA PFS(14.1 vs.9.5 months,P =0.001) and rPFS(16.4 vs.10.5 months,P ＜ 0.001)) has a longer median PSA PFS and rPFS respectively.In multivariate Cox analysis,baseline NED markers level and NED markers variation during the first 6 months of AA treatment remained significant predictors of rPFS(P ＜ 0.05),and PSA-PFS (P ＜ 0.05).Conclusions We found there was heterogeneity in changes of NED markers in different mCRPC patients during AA treatment,and AA might not significantly lead to progression of NED of mCRPC in general.Serial CgA and NSE evaluation might help clinicians guide clinical treatment of mCRPC patients.Serum NED markers elevation during the first 6 months of AA treatment and elevated baseline NED markers levels indicated poor prognosis in mCRPC treated with AA.

Objective:To investigate the value of T 1ρ mapping in the assessment of myocardial fibrosis in patients with hypertrophic cardiomyopathy (HCM). Methods:Forty HCM patients and 16 healthy volunteers who underwent CMR examination between December 2021 and May 2022 were prospectively enrolled. T 1ρ mapping, pre-and post-contrast T 1 mapping, and gadolinium contrast-enhanced delayed enhancement (LGE) imaging were performed in HCM patients, while T 1ρ mapping and T 1 mapping were performed in volunteers. HCM patients were further divided into LGE-positive (LGE+) and LGE-negative (LGE-) groups based on the presence or absence of LGE. The T 1ρ and pre-contrast T 1 values of the left ventricular myocardium of HCM patients and volunteers were measured, and the extracellular volume fraction (ECV) of the left ventricular myocardium of HCM patients was measured using pre-and post-contrast T 1 mapping. One-way ANOVA was used to compare the T 1ρ and pre-contrast T 1 values among the LGE+, LGE-, and volunteer groups, and pairwise comparisons were further corrected using the Bonferroni method. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance of pre-contrast T 1 and T 1ρ values in distinguishing LGE+ and LGE- patients from volunteers. The chi-square test or Fisher′s exact probability test was used for categorical variable comparisons. Pearson correlation coefficient was used to evaluate the correlation between T 1ρ and pre-contrast T 1, and ECV. Results:There were no significant differences in age, gender, and body surface area among the LGE+, LGE-, and healthy control groups ( P>0.05). Compared to the HC group, both the T 1ρ value ( t=5.74, P<0.001) and the pre-contrast T 1 value ( t=3.99, P<0.001) increased in LGE positive group, as well as in the LGE negative group (T 1ρ: t=4.19, P<0.001; T 1: t=2.06, P<0.044). ROC analysis showed that the area under the curve (AUC) of T 1ρ and pre-contrast T 1 in distinguishing LGE+patients from healthy controls were 0.93 (sensitivity 84.0%, specificity 93.8%) and 0.87 (sensitivity 84.0%, specificity 87.5%), respectively. The AUC of T 1ρ and pre-contrast T 1 in distinguishing LGE-patients from healthy controls were 0.84 (sensitivity 86.7%, specificity 68.8%) and 0.68 (sensitivity 60%, specificity 68.8%), respectively. The correlation analysis showed that the T 1ρ value of the left ventricular myocardium was positively correlated with the pre-contrast T 1 value ( r=0.31, P=0.02) and ECV value ( r=0.38, P=0.02). Conclusion:Without the use of contrast agents, T 1ρ mapping shows good performance for myocardial replacement fibrosis and diffuse fibrosis in HCM patients.
