Research progress on analgesic effect and adverse drug reactions of opioid receptor agonist-antagonists / 中国药房

Opioid receptor agonist-antagonists are a class of drugs which have both agonistic and antagonistic effects on opioid receptors. These drugs already on the market mainly include pentazocine， butorphanol， nalbuphine， buprenorphine， dezocine and so on. Compared with pure opioid receptor agonists such as morphine and fentanyl， these drugs have strong analgesic effects， less addictive， and less side effects such as cough， itching and respiratory depression. Due to the different tendentious effects of opioid receptor agonists-antagonists among different endogenous opioid receptors （μ， κ， δ， etc.）， different receptors of subtypes can exhibit different or even opposite effects in terms of affecting emotions and drug dependence. Therefore， the rational use of these drugs can effectively reduce the occurrence of adverse reactions and drug abuse caused by opioid drugs. With the deepening of research on various endogenous opioid receptor subtypes and related drugs in the academic community， opioid receptor agonists- antagonists have broad application space and prospects in improving adverse reactions to opioid drugs and enhancing patient drug compliance.

Objective To evaluate the effect of positive end-expiratory pressure (PEEP) on intraoperative pulmonary function in the patients undergoing urological retroperitoneal laparoscopic surgery in the mode of protective ventilation.Methods Forty patients of both sexes,aged 30-64 yr,with body mass index of 16-29 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective retroperitoneal laparoscopic ureterolithotorny,were randomly divided into 2 groups (n =20 each) using a random number table:control group (group C) and PEEP group (group P).After induction of general anesthesia,the patients were endotracheally intubated.Intermittent positive pressure ventilation (tidal volume [Vr] 6 ml/kg,respiratory rate [RR] 12 breaths/min,inspiratory/expiratory ratio [I:E] 1:2,fraction of inspired oxygen 50％) was performed from the end of intubation until the onset of pneumoperitoneum.After the onset of pneumoperitoneum,the patients were ventilated (VT 6 ml/kg,RR 22 breaths/min,I:E 1.0:1.5),and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg in group C.After the onset of pneumoperitoneum,the patients were ventilated (VT 6 ml/kg,RR 22 breaths/min,I:E1.0:1.5,PEEP 5 cmH2O),and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg in group P.At 5 min before pneumoperitoneum (T1),at 10,30 and 60 min of pneumoperitoneum (T2-4),immediately after the end of pneumoperitoneum (T5),and at 5 min before extubation (T6),arterial blood samples were collected for blood gas analysis.Peak airway pressure and mean airway pressure were also recorded.Dynamic lung compliance,oxygenation index,respiratory index,dead space fraction and alveolararterial oxygen gradient were calculated.Results Compared with group C,mean airway pressure was significantly higher at T2-4,oxygenation index was significantly higher at T3,alveolar-arterial oxygen gradient difference was significantly lower at T3 and T6,and respiratory index was significantly lower at T6 (P＜0.05),and no significant change was found in the peak airway pressure,dynamic lung compliance and dead space fraction at each time point in group P (P＞0.05).Conclusion PEEP (5 cmH2O) can improve the intraoperative pulmonary function in the patients undergoing urological retroperitoneal laparoscopic surgery in the mode of protective ventilation.

Screening and expression analysis of the specific tissue and serum microRNA profile in Hirschsprung disease / 中华实用儿科临床杂志

Objective To investigate the different expressions of pathological tissue and serum microRNAs (miRNAs)in Hirschsprung disease(HSCR). Methods Pathological colon tissues and serum samples were obtained from 52 confirmed HSCR cases respectively by surgery and pathology and from 52 matched controls,respectively. An initial screening of the tissues and serum microRNA expression were performed through TaqMan Low Density Array. The candidate tissue and serum miRNAs were validated by quantitative real - time - PCR in the 20 paired array samples and extra 32 paired samples after the integration of the screening result. The bioinformatical software online including miR-base,Target Scan,PicTar and MiRanda were used to predict the target mRNA of the consistent microRNAs in the tis-sues and the serum. Results Compared with the controls,47 microRNAs were differently expressed in HSCR tissues, including 17 up - regulated miRNAs and 30 down - regulated miRNAs;32 upregulated miRNAs were also detected to be differently expressed in the HSCR serum. Among these microRNAs,miR - 218 - 1 and miR - 885 - 5p were identi-fied to have a consistent significant different expression in both tissues and the serum,which were validated as high -expressed in microarray samples and expanded 32 paired samples(miR - 218 - 1:tissue array 0. 017 58 ± 0. 002 29 vs 0. 003 37 ± 0. 000 50,P ﹤ 0. 001;tissue expanded expression 0. 013 53 ± 0. 001 74 vs 0. 004 43 ± 0. 000 60,P ﹤0. 001. miR - 885 - 5p:tissue array 0. 000 30 ± 0. 000 11 vs 0. 000 04 ± 0. 0000 08,P = 0. 027 6;tissue expanded ex-pression 0. 004 59 ± 0. 000 16 vs 0. 000 04 ± 0. 000 01,P = 0. 014 5. miR - 218 - 1:serum array 0. 769 60 ± 0. 285 50 vs 0. 045 14 ± 0. 015 07,P = 0. 015 5;serum expanded expression 1. 151 00 ± 0. 430 00 vs 0. 023 07 ± 0. 003 81,P =0. 008 7. miR -885 -5p:serum array 1. 595 00 ±0. 441 70 vs 0. 169 40 ±0. 034 46,P =0. 001 2;serum expanded expres-sion 1. 689 00 ±0. 453 00 vs 0. 146 10 ± 0. 031 24,P = 0. 001 2). Specifically,the target genes of these 2 microRNAs were RET,PLAG1 and NeuroD1,which had been reported to be directly related to HSCR. Conclusions Significantly dif-ferential expressed miRNAs exist in the pathological tissue and the serum of HSCR. MiR - 218 - 1 and miR - 885 - 5p, which showing consistent differential expression,may be involved in the pathogenesis of HSCR.
