Objective To assess the association of serum resistin,TNF-? and insulin resistance in type 2 diabetes mellitus.Methods 42 cases of T2DM and 40 cases of control were involved in the study.Their waist circumference(WC),the levels of fasting serum resistin,TNF-?,fasting blood glucose(FBG) and fasting insulin(FINS)were measured.Results The levels of serum resistin,TNF-? and Homa-IR in T2DM group were significantly higher than those in control group,while serum FINS level was significantly lower than that in control group[(11.76?2.72)vs(8.65?3.00)?g/L,P

The carotid initima-media thickness(CIMT)in 78 cases of type 2 diabetic patients was measured.The level of plasma endogenous secretion receptor for advanced glycation end-products(esRAGE)in patients with normal CIMT was higher than those with chickened CIMT[(0.257 3±0.165 6 vs 0.155 4±0.0701)μg/L,P<0.01].esRAGE was negatively associated with CIMT(r=-0.247,P<0.05).Logistic regression analysis showed that CIMT was negatively associated with esRAGE and hish density lipoprotein cholesterol,but was positively associated with age.

Objective: To evaluate the role of mitochondrion-dependent apoptosis in reduction of bupivacaine-induced cardiotoxicity by lipid emulsion in rats. Methods: Forty-five healthy adult male Sprague-Dawley rats, weighing 300-350 g, were divided into 3 groups by a random number table method: sham operation group (Sham group, n=5), bupivacaine group (B group, n=20), and lipid emulsion group (L group, n=20). Cardiac arrest was induced by intravenously injecting 0.4% bupivacaine 30 mg/kg over 20 s to establish the cardiotoxicity model.Twenty percent lipid emulsion was intravenously injected in a dose of 5 ml/kg during resuscitation in group L, and normal saline was intravenously injected in a loading dose of 5 ml/kg during resuscitation in group B, followed by a 3-min infusion of 1 ml·kg^-1·min^-1in two groups.The successful resuscitation and survival rate at 120 min of return of spontaneous circulation (ROSC) were recorded.Systolic blood pressure, heart rate, mean arterial pressure, rate-pressure product (RPP) and ratio of RPP at each time point after recovery of spontaneous heart beat to baseline value (RPPh) were recorded every 10 min after ROSC.The time from administration to cardiac arrest (T₀), time from beginning of cardiopulmonary resuscitation to appearance of the first spontaneous heart beat (T_s) and time from beginning of cardiopulmonary resuscitation to appearance of ROSC (T_r) were recorded.Rats were sacrificed at 120 min of ROSC, and left ventricular tissues were obtained for determination of the expression of Bax, Bcl-2, cleaved caspase-9, cleaved caspase-3, cytochrome C (Cyt c) in cytoplasm and mitochondria (by Western blot) and expression of Bax and Bcl-2 mRNA (by real-time polymerase chain reaction) and for examination of myocardial ultrastructure. Results: Compared with Sham group, the expression of Bcl-2 protein and mRNA and mitochondrial Cyt c was significantly down-regulated, and the expression of Bax protein and mRNA, cleaved caspase-9, cleaved caspase-3 and cytoplasmic Cyt c was up-regulated in B group (P<0.05). Compared with B group, the rate of successful resuscitation and survival rate were significantly increased, T_r was shortened, systolic blood pressure, heart rate, RPP and RPPh were increased after ROSC, the expression of Bcl-2 protein and mRNA and mitochondrial Cyt c was up-regulated, the expression of Bax protein and mRNA, cleaved caspase-9, cleaved caspase-3 and cytoplasmic Cyt c was down-regulated (P<0.05), no significant change was found in T_o or T_s (P>0.05), and the pathological changes of myocardium were significantly attenuated in L group. Conclusion The mechanism by which lipid emulsion reduces bupivacaine-induced cardiotoxicity may be related to inhibiting mitochondrion-dependent apoptosis in rats.

Objective To explore the effect and mechanism of microRNA (miR)-17-5p on the invasion and metastasis of hepatocellular carcinoma (HCC) cells. Methods Expression of miR-17-5p in the normal human L-02 hepatocyte and QGY-7703 HCC cells was detected by RT-PCR. QGY-7703 HCC cells were transfected by miR-17-5p mimic and mimic control respectively. Influence of miR-17-5p on the invasion and metastasis ability of HCC cells was detected using Transwell assay and scratch test. Target gene of miR-17-5p was confirmed by bioinformatic analysis, and its expression in HCC cells was detected by Western blot. After siRNA silenced by target gene, the invasion and metastasis ability of HCC cells were observed. Comparison of microRNA in the two kinds of cells was conducted by t test. Results Expression level of miR-17-5p in HCC cells was 0.16±0.04, significantly lower than 1.01±0.19 in normal L-02 hepatocytes (t=-9.67, P<0.05). Number of trans-membrane cells and metastasis rate of HCC cells transfected by miR-17-5p mimic were respectively 36±4 and (5.37±0.15) mm/d, significantly lower than 62±7 and (7.50±0.01) mm/d of control group (t=-15.40, -32.00; P<0.05). Bioinformatic analysis showed that AKT3 was the key target gene of miR-17-5p, and the expression of AKT3 in HCC cells was obviously higher than that of normal hepatocyte. Number of trans-membrane cells and metastasis rate of HCC cells transfected by siRNA-AKT3 were respectively 13±3 and (4.13±0.15) mm/d, significantly lower than 58±3 and (7.23±0.25) mm/d of control group (t=-17.88, -53.69; P<0.05). Conclusion miR-17-5p inhibits the invasion and metastasis ability of HCC cells through targeting effect on AKT3.

Objective:To comprehensively and systematically collect and review domestic and international studies on the practices of continuous bladder irrigation (CBI) following transurethral resection of the prostate (TURP), including the topics, research methods, and evaluation techniques used in these studies, and to provide clinical nursing staff with a reference.Methods:Nine Chinese and English databases were systematically searched, including CNKI, Wanfang, SinoMed, VIP, Embase, Cochrane Library, PubMed, CINAHL, and Web of Science. The search covered all literature up to April 10, 2023. The practices of CBI were extracted and systematically analyzed, and the results were reported in a standardized manner using a scoping review methodology.Results:A total of 23 eligible studies were included, comprising two English articles and 21 Chinese articles. The types of studies included 12 randomized controlled trials and 11 quasi-experimental studies. The interventions were categorized into single and comprehensive measures, including methods such as adjusting the temperature and flow rate of bladder irrigation, selection of indwelling catheters, traditional Chinese medicine-based nursing, perioperative psychological care, and rapid recovery protocols. The evaluation metrics used in the studies were classified into three levels: symptom indicators, process indicators, and management indicators.Conclusions:Research on CBI following TURP has achieved a certain scale, with a variety of intervention methods currently available. However, there is still a lack of high-quality evidence. Future studies should focus on enhancing research design, developing standardized quality assessment tools for bladder irrigation, and improving innovative irrigation devices to enhance clinical nursing quality.
