Objective To investigate the expression and significance of miR?135a?5p in endometrial carcinoma and to correlate expression levels with clinicopathological features. Methods Fifty five endometrial carcinoma samples and thirty normal endometrial tissue samples were surgically obtained,and the expression of miR?135a?5p was quantitated by real?time polymerase chain reaction. The relationship between the expression level of miR?135a?5p and clinicopathological data of individual patients was analyzed. Results The expression of miR?135a?5p was lower in the endo?metrial carcinoma group than in the normal endometrial group(P=0.021),and correlated significantly with the histologic grade of the endometrial neoplasm(P=0.008). Conclusion The expression of miR?135a?5p is lower in endometrial carcinoma than in normal endometrial tissue. In en?dometrial carcinoma,the miR?135a?5p expression status has a statistically significant relationship with the histological characteristics of the tumor.

Objective To systematically evaluate the efficacy and safety of ciprofol for sedation and anesthesia outside the operating room.Methods Databases such as PubMed,Embase,Cochrane Library,Web of Science,CNKI,Wanfang Data,CBM,and VIP were searched for randomized controlled trials(RCTs)related to the efficacy and safety of ciprofol for sedation and anesthesia outside the operating room.The search covered all publications up to June 2023.Statistical analysis was performed using RevMan 5.4 software and Stata 15.0.Results Twelve RCTs were included,involving 2 192 patients,of which 1 154 were in the ciprofol group and 1 038 in the propofol group.Compared with the propofol group,the anesthesia induction time(MD=0.28 min,95％CI 0.08-0.47 min,P=0.006)and recovery time(MD=1.16 min,95％CI 0.44-1.87 min,P=0.001)were significantly longer in the ciprofol group,and the inci-dences of injection pain(OR=0.04,95％CI 0.02-0.06,P＜0.001),hypotension(OR=0.64,95％CI 0.49-0.83,P=0.0008),hypoxemia(OR=0.44,95％CI 0.21-0.91,P=0.03),and respirato-ry depression(OR=0.19,95％CI 0.11-0.32,P＜0.001)were significantly lower.There were no sta-tistically significant differences between the two groups in terms of sedation success rate,physician satisfac-tion,the difference in heart rate before and after anesthesia induction,incidence of body movement,brady-cardia,nausea and vomiting,and dizziness.Conclusion The anesthetic effect of cyclopofol and propofol is similar when used for anesthesia outside the operating room.Compared to propofol,ciprofol offers comparable anesthetic effects for sedation and anesthesia outside the operating room,with a lesser impact on respiratory function and more stable hemodynamics.Ciprofol also significantly lowers the incidence of adverse reactions such as injection pain,hypotension,hypoxemia,and respiratory depression.
