ABSTRACT

Idiopathic macular membrane (iERM) is a fibrocellular membrane that forms on the inner surface of the retina. In its early stages, symptoms of iERM are usually not apparent. However, advanced iERM can cause different degrees of visual impairment and effect the quality of life of patients. Current studies suggest that iERM may be associated with posterior vitreous detachment (PVD), age, sex, race and/or ethnicity, poor lifestyle, refractive error, diabetes, hypercholesterolemia, and cardiovascular disease. The most well-established risk factors for iERM are age and PVD. The pathogenesis of iERM is extremely complex. Various cell types, such as Müller cells, Hyalocytes and myofibroblasts, nerve growth factor, interleukin-6, transforming growth factor β, vascular endothelial growth factor and other cytokines and growth factors, as well as a variety of genes and proteins are directly or indirectly involved in the formation of iERM, however, their exact role remains a mystery. In the future, further studies at the molecular level and gene level are needed to provide greater help for the clinical diagnosis and treatment of iERM.

ABSTRACT

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on perioperative anxiety and postoperative pain in living kidney donors (LKDs).Methods:Seventy-two American Society of Anesthesiologists physical status Ⅰ or Ⅱ LKDs, aged 18-64 yr, with body mass index of 18-28 kg/m 2, undergoing living kidney transplantation, were selected, and divided into 2 groups ( n=36 each) using a random number table method: TEAS group (group T) and sham stimulation group (group S). In group T, TEAS was performed on the forenoon at 1 day before surgery (T 0), at 30 min before anesthesia induction on the morning of the operation day (T 1) and on the forenoon at 1 day after surgery (T 2) at bilateral Neiguan, Taichong and Yintang with a frequency 2-100 Hz, disperse-dense waves and current intensity 6-15 mA, and each TEAS lasted for 30 min.Only electrode patches were applied at the same acupoint and at the same time point, but no stimulation was applied in group S. In T and S groups, brachial venous blood samples were collected before each stimulation for measurement of the plasma 5-hydroxytryptamine (5-HT) concentration.The Hospital Anxiety Depression Scale-Anxiety subscale (HADS-A) scores at T 0, T 1, T 2, on day 3 after surgery (T 3) and before discharge (T 4) in the 2 groups were recorded.The consumption of anesthetics during operation, laryngeal mask airway removal time, requirement for rescue analgesia within 72 h after surgery and the development of postoperative complications were recorded.The LKDs were followed up by telephone at 3 months after surgery (T 5) to record the scores of HADS-A and Leeds Assessment of Neuropathic Symptoms and Sign (LANSS) scale. Results:Compared to group S, the incidence of anxiety was significantly decreased T 1, T 2 and T 3, the incidence of rescue analgesia within 72 h after surgery was decreased, plasma concentration of 5-HT was increased at T 1 and T 2, the incidence of postoperative nausea and vomiting was decreased, and the time to first flatus was shortened in group T ( P<0.05). There was no significant difference in the consumption of anesthetics during operation, laryngeal mask airway removal time, and the incidence of anxiety and neuropathic pain within 3 months after surgery between the 2 groups ( P>0.05). Conclusion:TEAS can relieve early preoperative and postoperative anxiety and alleviate postoperative pain in LKDs.

ABSTRACT

Bile acids facilitate the absorption of lipids, and affect the development of various diseases by regulating intestinal flora structure and modulating immunity and metabolism. It is therefore important to quantitatively detect bile acids. Current analytical methods are still immature due to constituent complexity, structural heterogeneity and bioactive variability of bile acids. Detection of individual bile acids is of significance for pharmacological research, clinical diagnosis and disease prevention. Advances have been made in bile acid analysis from multiple sources including serum, bile, urine and feces, although several limitations still exist for bile acid quantification. Here we review research progress in conventional bile acid assays, including spectrophotometry, thin-layer chromatography, liquid/gas chromatography and liquid/gas chromatography-mass spectrometry. Moreover, we emphasize the development of bile acid biosensors that may have promising prospects.

ABSTRACT

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

ABSTRACT

Objective To investigate the management and clinical effect of accessory renal artery in living-related donor renal transplantation. Methods Clinical data of 277 donors and recipients undergoing living-related donor renal transplantation were retrospectively analyzed. According to the results of preoperative CT angiography (CTA), the donor kidney was selected and the accessory renal artery of the renal graft was treated intraoperatively. Intraoperative status of the donors, and intraoperative management, postoperative complications, clinical prognosis of the recipients were summarized. Results Among 277 cases of renal transplantation, accessory renal arteries were detected in 83 donors by preoperative CTA examination with an accuracy rate of 95%. Fifty-eight donor kidneys with accessory renal arteries were obtained. Twenty-five donor kidneys with accessory renal arteries were reconstructed and anastomized by vascular repairing. Among them, 1 patient presented with anastomotic thrombosis during abdominal closure, whereas the other 24 cases were successfully anastomized with excellent blood flow. No complications, such as hemorrhage, renal graft embolism, ureteral necrosis and urinary fistula, occurred after renal transplantation. The 1-year survival rates of the recipients and renal grafts were 94% and 91%. The clinical efficacy did not significantly differ between the recipients with single renal artery and their counterparts with accessory renal artery (P > 0.05). Conclusions It can be obtained good clinical efficacy of renal transplantation by selecting a suitable donor kidney and reconstructing and anastomizing the accessory renal artery of the renal graft through vascular repair.

ABSTRACT

Objective@#To study the effects of different holding gun methods and gun weight on health when standing guard, and propose a way to support the health of long-term standing guard soldiers.@*Methods@#We created different percentile mannequins by Classic JACK, and adjusted the standing guard posture based on its standards for soldiers. The pressure on lumbar L4/L5 and moment on ankles and knees were analysied for different holding gun methods and gun weight. Then the mathematical models of joint load, gun weight and body mass index were studied by multiple regression analysis.@*Results@#Holding gun methods and gun weight influence the force characteristics on ankles, knees and lumbar L4/L5. Holding gun with a brace and hands applying downward force -2 kgf could significantly reduce lumbar L4/L5 pressure. When the hand force is -5, -3, -4, -3, -2, -1, 0, 1, 2 kgf, and the weight of the gun is 0, Lumbar vertebrae L4/L5 joint pressure of people with different body mass index(P1, P5, P55, P95, P99) are the smallest, respectively 269, 281, 321, 408, 444 N, and the same change trend occurs when the weight of the gun is 2, 4, and 8 kg.The moment on ankles and knees were less with the same holding gun method and the hands downward force ranged from 0 to -4 kgf, and the higher the body mass index is, the more the hands downward force needed to make the moment on ankles and knees zero. That is, the moment on ankles could be zero when the hands downward force ranged from -1 to -3 kgf, the moment on knees could be zero when the hands downward force ranged from -1.1 to -3.7 kgf.@*Conclusion@#To reduce the pressure on lumbar L4/L5 and moment on ankles and knees, so as to cut down occupational risk of long-standing operation, we advise the long-term standing guard soldiers holding gun with a brace and hands applying downward force -2 kgf.

ABSTRACT

Objective@#To investigate the expression of microRNA-133b (miR-133b) in esophageal squamous cell carcinoma (ESCC), and explore its effect and the underlying molecular mechanisms on cell proliferation and invasion.@*Methods@#Real-time quantitative PCR (qPCR) was used to examine miR-133b expression in 63 ESCC tissues and paired adjacent non-cancerous tissues, several ESCC cells (Eca109, EC9706, EC1, TE1, KYSE70) and normal esophageal epithelial cell Het-1A. MiR-133b mimic, inhibitor and negative control (NC) were transfected into TE1 cells. The effect of miR-133b on cell proliferation and invasion were determined by CCK-8 and Transwell assays, respectively. Subsequently, the target gene of miR-133b was predicted by online tools TargetScan and miRDB, which was verified by dual luciferase reporter assays. Finally, Western blot was utilized to detect the effects of miR-133b overexpression on expression of target gene TAGLN2 as well as EMT-related proteins E-cadherin, N-cadherin, Snail, Slug and Vimentin.@*Results@#Relative levels of miR-133b in ESCC tissues (0.295±0.040) were significantly lower than those in adjacent non-cancerous tissues (1.002±0.011, P<0.001). The expression of miR-133b was tightly associated with clinical staging, lymph node metastasis and prognosis. Moreover, relative levels of miR-133b in ESCC cells Eca109, EC9706, EC1, TE1 and KYSE70 (0.679±0.031, 0.391±0.008, 0.236±0.016, 0.031±0.005 and 0.099±0.020) were evidently lower than that in normal esophageal epithelial cell Het-1A (1.005±0.016, all P<0.001). In TE1 cells, miR-133b mimic significantly increased the level of miR-133b to 6.199±0.627, and suppressed cell proliferation and invasion, whereas miR-133b inhibitor obviously decreased its expression to 0.182±0.023, and promoted cell proliferation and invasion. Most notably, the relative luciferase activities of miR-133b-mimic group (0.320±0.018) in TE1 cells transfected with TAGLN-3′UTR-WT were markedly lower than that in NC group (1.010±0.036, P<0.001), whereas those in TAGLN-3′UTR-MUT transfection cells were 1.019±0.056 and 1.008±0.021, respectively, showing no significantly statistical difference (P>0.05). Furthermore, miR-133b overexpression markedly downregulated TAGLN2, N-cadherin, Snail, Slug and Vimentin levels, and increased E-cadherin expression.@*Conclusion@#MiR-133b plays an important role in the proliferation and invasion of ESCC cells by regulating TAGLN2 expression, and it may be a potential therapeutic target for ESCC patients.

ABSTRACT

OBJECTIVE: To systematically evaluate the effects of Shenqi fuzheng injection combined with conventional chemotherapy on the immune function of patients with advanced non-small cell lung cancer (NSCLC), and provide evidence-based reference for clinical medication. METHODS: Retrieved from Cochrane Library, PubMed, Medline, Embase, CNKI, Wanfang database, VIP and CBM, Shenqi fuzheng injection combined with conventional chemotherapy (trial group) versus conventional therapy (control group) for advanced NSCLC were collected. After literature screening, data extraction and quality evaluation with Cochrane system evaluator manual 5.1.0 risk evaluation tool, Meta-analysis was performed by using Rev Man 5.3 statistical software. RESULTS: A total of 16 literatures were included, involving 1 324 cases. Results of Meta-analysis showed that there were no statistical significance in the difference of objective remission rate (ORR) [RR=1.14, 95%CI(0.91,1.43), P=0.25] and the level of  CD8+ [MD=-1.26,95%CI(-4.10, 1.59),P=0.39] between 2 groups. The levels of CD3+ [MD=17.48, 95%CI(13.40, 21.56), P<0.000 01 ], CD4+[MD=12.26, 95%CI(8.39 16.13), P<0.000 01], CD4+/CD8+ [MD=0.33,95%CI(0.27, 0.39),P<0.000 01] and the percentage of NK cells [MD=9.33, 95%CI(5.72, 12.94), P<0.000 01] in trial group were significantly higher than control group. Results of subgroup analysis for medication duration of Shenqi fuzheng injection showed that after 1-14 d treatment of Shenqi fuzheng injection, the levels of CD3+ [MD=17.11, 95%CI(12.37 ,23.17),P<0.000 01], CD4+[MD=13.28,95%CI(8.33, 18.23),P<0.000 01], CD4+/CD8+[MD=0.36,95%CI(0.28,0.43),P<0.000 01] and the percentage of NK cells [MD=12.06,95%CI(7.52,16.61),P<0.000 1] in trial group were significantly higher than control group. After 21 d treatment of Shenqi fuzheng injection, the levels of CD3+[MD=14.88, 95%CI(7.51,22.26),P<0.000 01], CD4+[MD=10.56,95%CI(5.57,15.56),P<0.000 01], CD8+[MD=3.02, 95%CI(1.80, 4.23),P<0.000 01], CD4+/CD8+[MD=0.29,95%CI(0.23, 0.35),P<0.000 01] and the percentage of NK cells [MD=5.58,95%CI(2.49, 8.67),P=0.000 4] in trial group were significantly higher than control group. There was no statistical significance in the level of CD8+ between 2 groups after 7-14 d treatment of Shenqi fuzheng injection [MD=-4.26,95%CI(-12.60, 4.09),P=0.32]. The incidence of leukopenia, nausea and vomiting, and renal dysfunction in trial group were significantly lower than control group. There was no statistical significance in the incidence of hemoglobin decreased and thrombocytopenia between 2 groups. The results of publication bias showed that there was a greater possibility of publication bias in this study. CONCLUSIONS: Shenqi fuzheng injection combined with conventional chemotherapy may improve the immune function of patients with advanced NSCLC and improve the safety after chemotherapy. But more large-scale, milltiple-center and high-quality RCT are needed to validate this conclusion.

ABSTRACT

OBJECTIVE: To establish a method for the concentration determination of apatinib mesylate in plasma of rats, and to investigate the effects of single and multiple administration of Wuzhi capsules on the pharmacokinetic behavior of apatinib mesylate in rats. METHODS:  LC-MS/MS method was used to detect the plasma concentration of apatinib mesylate in rats. Using carbamazepine as internal standard, the determination was performed on Waters XBridge BEH C18 column with mobile phase consisted acetonitrile-0.1% formic acid solution (45 ∶ 55,V/V) at the flow rate of 0.3 mL/min. The column temperature was 40 ℃. The temperature of injector was 15 ℃, and the sample size was 2 μL. ESI was used for positive ion scanning in MRM mode. The ion pairs m/z used for quantitative analysis were 398.1→212.1 (apatinib mesylate) and  237.2→194.2 (internal standard). The rats were randomly divided into control group Ⅰ, observation group Ⅰ, control group Ⅱ, observation group Ⅱ, with 6 rats in each group. Control group Ⅰ were given single administration of apatinib mesylate intragastrically (50 mg/kg, similarly hereinafter). Observation group Ⅰ was given Wuzhi capsules intragastrically (450 mg/kg, similarly hereinafter), and then 10 min later given apatinib mesylate intragastrically. Control group Ⅱ was given normal saline intragastrically, once a day, for consecutive 7 d, and then were given single administration of apatinib mesylate. Observation group Ⅱ was given Wuzhi capsules intragastrically, once a day, for consecutive 7 d, and then 10 min later were given single administration of apatinib mesylate. The blood samples were collected from intraocular canthus vein plexus and determined 0.25, 0.5, 1.0, 2.0, 2.5, 3.0, 4.0, 6.0, 8.0, 12.0, 24.0 h after intragastric administration, respectively. Pharmacokinetic parameters were apatinib mesylate were calculated and compared among those groups by using DAS 2.1 software and t-test. RESULTS: The linear range of apatinib mesylate were 2-2 000 ng/mL. The lower limit of quantitation was 2 ng/mL. RSDs of intra- day and inter-day were all lower than 10%, and the accuracy were 94.93%-104.68%. Matrix effect did not affect the quantitative analysis of the substance to be measured. Compared with control group Ⅰ, cmax, AUC0-24 h and AUC0-∞ of observation group Ⅰ were increased significantly, CLZ was decreased significantly (P<0.05). Compared with control group Ⅱ, AUC0-24 h and AUC0-∞ of observation group Ⅱ were increased significantly, and CLZ was decreased significantly (P<0.05). Compared with observation group Ⅰ, AUC0-24 h and AUC0-∞ of observation group Ⅱ were decreased significantly (P<0.05). CONCLUSIONS: Established LC-MS/MS method is sensitive and specific, and can be used for the concentration determination of apatinib mesylate in plasma of rats. Wuzhi capsules can influence in vivo pharmacokinetic behavior of apatinib mesylate in rats. The effect of multiple administration of Wuzhi capsules is weaker than that of single administration.

ABSTRACT

OBJECTIVE: To standardize the management of temporary drug purchase, and to provide reference for drug selection in Hospital Pharmaceutical Administration and Drug Treatment Committee (Pharmaceutical Association). METHODS: Clinical pharmacists set up drug quantitative scoring table according to the 10 attributes of drugs as effectiveness, safety, economy, etc. 15 temporary purchased drugs submitted by departments in Oct. 2018 were graded according to the rules of the scoring table, and the evaluation results were fed back to Pharmaceutical Association. A retrospective evaluation of 20 temporary purchased drugs which were discussed at the Pharmaceutical Association from Jul. to Sept. 2018 was made according to previous approval model without using drug quantitative scoring table. The effect of pre-intervention was evaluated after using drug quantitative scoring table. RESULTS: Among 15 temporary purchased drugs, 2 of them scored below 60, and the unqualified rate was 13.3%. It suggested that 2 drugs could not be discussed at the meeting. Among 20 temporary purchased drugs that have been discussed at the meeting, 9 of them scored below 60, with the unqualified rate of 45.0%, suggesting that 9 drugs may have wasted the workload of the Pharmaceutical Association. CONCLUSIONS: Drug quantitative scoring table can play a pre-intervention role in the scoring of temporary purchased drugs to a certain extent. At the same time, the table can also be used as a relevant reference for hospital drug evaluation. It is helpful to optimize hospital drug use list and improve the level of rational drug use in clinic.

ABSTRACT

Objective: To investigate the effects of WNT5B over-expression on the invasion and migration of human breast cancer MDA-MB-231 cells, and to explore its possible mechanisms. Methods: After the recombinant vector pcDNA3.1-WNT5B+EGFP containing enhanced green fluorescent protein (EGFP) and WNT 5B genes was transfected into human breast cancer MDA-MB-231 cells, the expression levels of WNT5B mRNA and protein were examined by real-time fluorescent quantitative PCR and Western blotting, respectively. The abilities of cell migration and invasion were analyzed by wound-healing test and Transwell chamber assay, respectively. Furthermore, the expression levels of epithelial-mesenchymal transition (EMT)-related molecules N-cadherin, E-cadherin and Vimentin were detected by Western blotting. Results: Compared with the untransfection and the empty vector-transfection groups, the expression levels of WNT5B mRNA (P < 0.01) and protein (P < 0.05) in MDA-MB-231 cells transfected with the recombinant vector pcDNA3.1-WNT5B+EGFP were up-regulated. The abilities of migration (P < 0.05) and invasion (P < 0.01) of MDA-MB-231 cells after WNT5B over-expression were significantly decreased. The expression level of E-cadherin in MDAMB- 231 cells with WNT5B over-expression was up-regulated (P < 0.05), whereas the expression levels of N-cadherin and Vimentin were down-regulated (both P < 0.05). Conclusion: WNT5B over-expression can inhibit the migration and invasion of breast cancer MDA-MB-231 cells, which may be related to the regulation of EMT process.

ABSTRACT

The inhibitory effect of NACOS on dyslipidemia and potential molecular mechanisms by in vitro and in vivo experiments were investigated. For in vitro study, four experimental groups were designed by using HepG2 cells, including the control group, palmitic acid (PA) treatment alone group, NACOS treatment alone group and NACOS + PA treatment group. For in vivo study, male C57BL/6 mice were divided into four groups (n=5) at random including the normal control group (NCD), high fat diet (HFD) group, NACOS treatment alone group, NACOS+HFD group, which were treated for 20 weeks. The used methods in this study were as follows: the observation of lipid droplet deposition in HepG2 cells by oil red O staining, the detection of mRNA levels of lipid metabolism-related regulators and inflammatory cytokine by RT-PCR method, the monitoring of MAPKs and PI3K/Akt pathway activation by Western blotting method. The in vitro study shows that, NACOS had no toxicity on the viability of HepG2 cells at 25-100 μg/mL and significantly reduced the deposition of lipid droplet. Also, based on both in vitro and in vivo investigation, NACOS evidently down-regulated the expression of lipid metabolism-related regulators (PGC1α, Cox5b, Mcad) and inflammatory cytokine (IL-1β) at mRNA level (P<0.05 or 0.01), and suppressed the activation of p38, ERK1/2 and Akt in HepG2 cells and lever tissues from HFD-fed mice (P<0.05 or 0.01). Based on the above, NACOS may inhibit the oxidation of liver mitochondrial fatty acid and the lipid biosynthesis, block the inflammatory responses and prevent the HepG2 cells and C57BL/6 mice from lipidemia.

ABSTRACT

The apical sodium--dependent bile acid transporter (ASBT) is the main transporter to promote re-absorption of bile acids from the intestinal tract into the enterohepatic circulation. Inhibition of ASBT could increase the excretion of bile acids, thus increasing bile acid synthesis and consequently cholesterol consumption. Therefore, ASBT is an attractive target for developing new cholesterol-lowering drugs. In this report, a series of 1-(2,4-bifluorophenyl)-7-dialkylamino-1,8-naphthyridine-3-carboxamides were designed as inhibitors of ASBT. Most of them demonstrated potency against ASBT transport of bile acids. In particular, compoundwas found to have the best activity, resulting in 80.1% inhibition of ASBT at 10 μmol/L.

Objective To study the safety and efficacy of accessory hepatic vein (AHV) stenting to treat primary Budd-Chiari syndrome (BCS).Methods The clinical data of 20 BCS patients with AHV ostial stenosis or occlusion were retrospectively analyzed.These 20 patients underwent balloon dilation and AHV stenting.Thirteen patients underwent AHV stenting via the right jugular vein approach,5 patients via the right femoral vein approach,and 2 patients via the percutaneous transhepatic combined with the right femoral vein approach.On follow-up,patency of the AHV stent was evaluated by color Doppler ultrasound.The cumulative primary and secondary patency rates were assessed with the Kaplan-Meier curves.Results AHV stenting was successful in 20 patients.Angiography showed that the AHV was patent after stenting.The mean pressure gradient between the AHV and the inferior vena cava reduced from (19.2 ± 4.8) cmH2O (1 cmH2O =0.098 kPa) before treatment to (4.5 ± 1.9) cmH2O after treatment (t =7.119,P < 0.01).During the procedure,rupture of the AHV caused by balloon dilation occurred in one patient.This was treated successfully by a covered stent placement.On follow-up from 1 to 80 months [(32.1 ±27.4) months]after treatment for the 20 patients,re-stenosis of the AHV were found in 5 patients.They were treated successfully with re-dilation.The cumulative 1-,3-,and 5-year primary patency rates were 100%,85.1% and 74.5%,respectively.The cumulative 1-,3-,and 5-year secondary patency rates were 100%,90.9% and 90.9%,respectively.One patient died of hepatic failure 3 years after the treatment.Conclusion AHV stenting was a safe and efficacious treatment for BCS and it provided good mid-and long-term results.

ABSTRACT

Objective To investigate the effects and mechanism of dexmedetomidine hydrochloride preconditioning against glutamate-induced neurotoxicity.Methods The model of glutamate-induced neurotoxicity was established by the injection of glutamate into lateral cerebral ventricle.Thirty-six SD rats were randomly divided into control group (C group),glutamate-induced neurotoxicity group (G group),Dex1 group and Dex2 group.Dex1 group and Dex2 group received intraperitoneal injection of dexmedetomidine respectively at a dose of 50 μg/kg or 100 μg/kg before glutamate application.Two hours later,the rats were sacrificed and hippocampus was separated to measure the level of SOD and MDA.The rest of each brain was used to measure the degree of brain edema.Pathological changes were observed under microscope with Nissl's staining.Results In contrast to G group,brain edema and MDA concentration in Dex1 group and Dex2 group were significant lower,while SOD concentrations were significantly increased and the pathological change in Dex1 group and Dex2 group were relieved obviously compared to glutamate-induced neurotoxicity group.Conclusion Dexmedetomidine preconditioning can significantly attenuate glutamate-induced neurotoxicity,which is properly related to the inhibition of oxidative-stress reaction.

ABSTRACT

The rapid recovery of postoperative gastrointestinal motility is the key factor to accelerate the recovery of patients. The recovery of gastrointestinal motility is often affected by various factors, such as anesthesia and operation. The present study shows that the inhibition of stress response caused by acute pain can improve the recovery of gastrointestinal motility. Howeve, the effects of perioperative intravenous analgesics on gastrointestinal motility are not consistent. So we reviewed the effects of different intravenous analgesics on gastrointestinal motility.

ABSTRACT

The Fe-N-C composite catalyst was prepared by the thermal decomposition of the chelate precursors based on Fe central ions and o-phenylenediamine ligands.It was observed from the scanning electron microscopy that the crumpled carbon micro-and nano-sheets were intertwined to form a free-standing tremella-like 3D structure.The N2 adsorption/desorption experiments revealed that the composite contained ample micro-and meso-pores and had a specific surface area of 290 m2/g.Graphitic C and multi-crystal Fe3C as main components were confirmed by the X-ray diffraction, and N-doping in the general form of graphite N and pyridine N was also verified by X-ray photoelectron spectroscopy.The electrochemical measurement showed that the tremella-like Fe-N-C composite catalyzed oxygen reduction through a four-electron path in an alkaline solution, and its activity was comparable to the commercial Pt/C catalyst.After 2000 cycles, the limited current density of the Fe-N-C catalytic electrode only decreased less than 5%, and the half-wave potential shift negatively 5 mV, which suggested that the Fe-N-C composite catalyst had better catalytic stability than the commercially used Pt/C catalyst.
