ABSTRACT
Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.
ABSTRACT
【Objective】 To investigate the safety, feasibility and clinical efficacy of modified anterior robot-assisted laparoscopic radical prostatectomy (RALRP) with preservation of Retzius space. 【Methods】 The clinical data of 10 patients who underwent RALRP using the modified anterior approach to preserve the Retzius space in our hospital during June 2021 and March 2022 were retrospectively analyzed, including the preoperative, intraoperative, postoperative and follow-up data. 【Results】 All operations were successful without conversion to open surgery. The average operation time (robotic arm operation time) was (98.6±47.7) min, blood loss (105.0±57.3) mL, postoperative drainage tube indwelling time (5.3±1.3) d, postoperative urinary catheter indwelling time (7.2±0.8) d, and postoperative hospital stay (9.2±2.2) d. Urinary continence was achieved immediately after removal of the urinary catheter in 6 patients, 2 patients recovered 2 weeks after extubation, and 2 patients recovered 3 months after extubation. Postoperative pathology showed pT2a stage in 1 case, pT2b stage in 2 cases, and pT2c stage in 7 cases; Gleason score was 6-7 points; all postoperative resection margins were negative. During the follow-up of 3-12 months, no tumor recurrence was observed, and no patient was readmitted due to surgical complications. 【Conclusion】 RALRP with modified anterior approach to preserve the Retzius space is safe and feasible, with no serious complications during and after surgery, and the early postoperative urinary continence effect is comparable to that of the posterior approach.
ABSTRACT
At present, the treatment of advanced tumors has entered the immune era, and immune checkpoint inhibitors have shown good efficacy in prostate cancer. Cellular immunotherapy such as CAR-T therapy (chimeric antigen receptor T-cell immunotherapy) has shown excellent results in hematological and digestive system malignancies, but its efficacy in urinary system tumors is not yet clear. This review will explain the current status and application prospects of CAR-T in the treatment of prostate cancer, including target selection, predicament, and function enhancement strategies of CAR molecules in prostate cancer, aiming to open up new perspectives for cellular immunotherapy of prostate cancer and ideas.
ABSTRACT
Objective To study the clinical characteristics in the patients with different types of acute coronary syndrome(ACS) undergoing percutaneous coronary intervention (PCI) and the factors affecting the PCI treatment.Methods A total of 377 inpatients with ACS undergoing PCI in this hospital from January 2014 to March 2015 were selected,including 172 cases of ST-elevation acute coronary syndrome (ST-ACS) group and 205 cases of non-ST-elevation ACS (NST-ACS group).The baseline data and detection indexes were collected,the GRACE score on admission was calculated,the database was established,regular follow-up was performed,and the prognosis was analyzed.Results The smoking history,emergency PCI,coronary angi-ography TIMI grade ≤ 1,H MGB1,GRACE score,heart rate on admission,white blood cell(WBC) count,neutrophil ratio,lymphocyte ratio,monocytes ratio,absolute neutrophil count,high density lipoprotein,apolipoprotein b,number of lesion vessels and left ventricular ejection fraction had statistical differences between the ST-ACS group and NST-ACS group (P ＜ 0.05);the correlation analysis showed that HMGB1 and GRACE score were significantly correlated (r=0.836,P＜0.01).The 2-year follow-up results showed that the previous myocardialinfarction and PCI history,Killip grade(Ⅱ-Ⅳ),coronary angiography TIMI grade≤ 1,HMGB1,GRACE score,mean platelet volume,age and number of lesion vessels had differences between the end point event occurrence group and end point event non-occurrence group (P＜0.05).The Logistic regression analysis showed that HMGB1,GRACE score,age,previous PCI histoty,Killip grade (Ⅱ-IV) were the independent risk factors for cardiovascular events (P ＜ 0.05).The Cox survival analysis showed that HMGB1,previous PCI history,Killip grade (Ⅱ-Ⅳ) were the independent risk factors for cardiovascular events (P＜0.05).The ROC survival curve showed that the accuracy of HMGB1 was good,the areas under the curve was 0.844 (95％CI:0.803-0.885,P＜0.05),the critical value predicting the end point events was 480.44 ng/mL.Conclusion HMGB1 has difference between the ST-ACS group and NST-ACS group,and has a good correlation with GRACE score.
ABSTRACT
Objective To investigate the impact of high mobility group box1 and GRACE score on the clinical prognosis of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention. Methods A total of 380 consecutive patients initially diagnosed with acute coronary syndrome undergoing selec-tive PCI between January 2014 and March 2015 were included,with 200 of them assigned into low high mobility group box1(HMGB1<445 ng/mL)and the other 180 patients into high mobility group box1(HMGB1≥445 ng/mL).The baseline characteristics and laboratory indexes were collected on admission,GRACE score were calculat-ed at admission.The difference between the high and low high mobility group box1 were analzyed and the influenc-ing factors of patients with acute coronary syndrome undergoing selective percutaneous coronary intervention were studied. The mean follow-up period was 24 months,and the clinical end points were deaths from various causes and readmission for coronary heart disease. Results There were significantly differences statistically between the groups of high and low high mobility group box1 in clinical diagnosis. lipoprotein associated phospholipase A2, GRACE score,mean platelet volume,red cell distribution width,age,and left ventricular ejection fraction(P <0.05). The correlation analysis showed that HMGB1 was significantly related to lipoprotein associated phospholi-pase A2 and GRACE score,with the correlation coefficents of 0.575,0.836,respectively(P<0.05).COX analy-sis showed that HMGB1,lipoprotein associated phospholipase A2,GRACE score had statistical significance for survival outcomes(P<0.05),and the area under the ROC curve drawn by combining the three was 0.851(95% CI 0.811 ~ 0.891,P < 0.05). Conclusion There was a good correlation between HMGB1 and GRACE score. HMGB1 is a good predictor of clinical outcomes in the patients with acute coronary syndromes undergoing elective PCI treatment.
ABSTRACT
Objective To analyze the therapeutic effect of intracoronary versus intravenous bolus tirofiban on myocardial perfusion and major cardiovascular events (MACE) in elderly patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and explore the optimal route of tirofiban application. Methods From July 2009 to July 2010, 120 NSTE-ACS patients undergoing percutaneous coronary intervention (PCI ) were consecutively enrolled in this study. They were randomly divided into two groups: intracoronary (60 cases) versus intravenous (60 cases) bolus tirofiban. Thrombolysis in myocardial infarction (TIMI) flow, TIMI myocardial perfusion grade (TMPG) and MACE 30 days after PCI were observed. Results The incidence of TIMI flow and TMPG 3 grade in intracoronary group were higher than in intravenous group [53(88.3%) vs. 38(63.3%); 53(88.3%) vs. 40(66.7%), respectively, both P＜0.05]. However, MACE incidence and bleeding complications during hospital 30 days after PCI had no significant difference between the two groups [1 (1.7%) vs. 0; 3(5.0%) vs. 5(8.3%)], which were not statistically significant (P＞0.05). Conclusions Intracoronary bolus tirofiban before PCI more effectively increases coronary blood flow and myocardium blush than intravenous route in elderly NSTE-ACS patients.
