Objective To systematically evaluate the effects of total intravenous anesthesia and inhalational anesthesia on postoperative recovery in patients undergoing transsphenoidal pituitary tumor resection.Methods A comprehensive search was conducted in international biomedical databases including Ovid Medline,Embase,CINAHL(EBSCO),Cochrane Library,and Web of Science,from inception to July 4,2023.Additionally,ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing and completed trials.The randomized controlled trials(RCT)comparing total intravenous anesthesia and inhalational anesthesia in patients undergoing transsphenoidal surgery for pituitary tumors were included.The methodological quality of the included studies was evaluated by the Cochrane Collaboration tool.Relevant data were extracted and synthesized for analysis.Results A total of 327 records were identified,of which eight RCTs met the inclusion criteria.Four studies showed that the patients receiving desflurane or sevoflurane anesthesia experienced faster emergence from anesthesia than those receiving propofol.Two studies indicated that patients in the propofol group had lower levels of emergence agitation and a lower incidence of early postoperative nausea and vomiting.The results on postoperative cognitive function were inconsistent across studies.No differences were found between the groups in terms of postoperative complications or overall recovery quality during hospitalization.Conclusions Inhalational anesthesia appears to provide an advantage in promoting faster emergence following transsphenoidal pituitary surgery,whereas total intravenous anesthesia may contribute to smoother and more stable recovery.Further high-quality studies are needed to clarify the effects of different anesthetic techniques on both short- and long-term postoperative recovery.

To identify the possible factors that may influence the success and the complications of ultrasound-guided out-of-plane radial arterial cannulation. Multivariate Logistic regression analysis was used to analyze the clinical data of 131 patients undergoing elective surgery and ultrasound-guided out-of-plane radial artery cannulation,dynamic needle tip positioning(DNTP) technique or angular distance(AD) technique and to find out the factors associated with the one-attempt success rate,overall success rate,posterior arterial wall perforation,and local hematoma. The depth of the anterior arterial wall≥3 mm was the factor associated with posterior arterial wall perforation(=0.314,95%:0.143-0.691,=0.004) and local hematoma(=0.250,95%:0.107-0.585,=0.001).The use of DNTP method was significantly associated with posterior arterial wall perforation(=0.303,95%:0.138-0.667,=0.003). During ultrasound-guided out-of-plane radial cannulation,puncture at the arterial anterior wall sites with a depth of≥3 mm can reduce the incidence of posterior arterial wall perforation and local hematoma.Compared with AD,DNTP can lower the incidence of posterior arterial wall perforation.

Objective Identification of the risk factors for extraordinary hidden blood loss (HBL) could clarify the underlying causes and provide more appropriate management. This study aims to identify the predictors of HBL in spinal surgery.Methods Medical records were retrospectively retrieved to collect the data of patients who undergoing posterior thoracic and lumbar fusion surgery or scoliosis surgery. Demographic information, perioperative visible blood loss volume, as well as laboratory results were recorded. The patients receiving fusion surgery or scoliosis surgery were further divided into the HBL positive subgroup and the HBL negative subgroup. Differences in the variables between the groups were then analyzed. Binary logistic regression analysis was performed to determine independent risk factors associated with HBL.Results For patients undergoing posterior spinal surgery, the independent risk factors associated with HBL were autologous transfusion (for fusion surgery P=0.011, OR: 2.627, 95%CI: 1.574-2.782; for scoliosis surgery P<0.001, OR: 2.268, 95%CI: 2.143-2.504) and allogeneic transfusion (for fusion surgeryP<0.001, OR: 6.487, 95%CI: 2.349-17.915; for scoliosis surgery P<0.001, OR: 3.636, 95%CI: 2.389-5.231).Conclusions Intraoperative blood transfusion might be an early-warning indicator for perioperative HBL.

To achieve fast and accurate analysis of weak current signal of nanopore-based single molecule detection, we designed a real-time adaptive threshold data processing algorithm with data buffering technique and finite impulse response filtering. The system, which is designed based on the data processing algorithm, could realize real-time recognition and analysis of nanopore events during the data recording process. In order to verify the performance of the system, the ideal signals with different noise level (20-100 pA) and recording bandwidth (3 - 100 kHz) was generated. The results showed that the system was stable to analyze the generated signals even at high noise. In addition, the system was also suitable for the data recording conditions of low bandwidth and high sampling rate (250 kHz). The proposed nanopore data processing system was further applied in the Aerolysin nanopore experiment for the detection of poly(dA) 4 molecules. The results showed that the data processing system could be applied in real nanopore recording system with high accuracy and speed.

Objective To evaluate the application of adding ondansetron in morphine intravenous analgesia pump for prevention of postoperative nausea and vomiting(PONV)in women. Methods Data of surgical female inpatients who received general anesthesia and postoperative intravenous analgesia with morphine in our center from January 1st,2013 to December 31st,2014 were retrospectively analyzed. Based on whether ondansetron was added,patients were divided into the observation group(n=834) and the control group(n=856). Outcome variables including morphine consumption,visual analogue scale(VAS) score,nausea score,and total times of vomiting within 48 hours after surgery were collected and compared. Results Age(t=0.432,P=0.665),morphine consumption during the first post-operative day(t=0.599,P=0.548) and during the second post-operative day(t=0.236,P=0.813),maximum VAS score of postoperative pain during movement during the first post-operative day [3(2,4) vs. 3(2,5);Z=1.850,P=0.064] and at rest during the second post-operative day [0(0,1) vs. 0(0,1);Z=1.511,P=0.131] were not significantly different between two groups. While the maximum VAS score of postoperative pain at rest during the first post-operative day [0(0,2) vs.0(0,2);Z=2.435,P=0.015] and during movement during the second post-operative day [3(1,3)vs.3(2,4);Z=3.445,P=0.001] were significantly different between two groups. The maximum score of postoperative nausea(χ=9.810,P=0.020) and cumulative frequency of postoperative vomiting(Z=3.726,P=0.002)in the observation group were significantly lower than those in the control group during the first post-operative day;however,there was no significant difference during the second post-operative day(χ=5.017,P=0.170;Z=0.000,P=1.000). Logistic regression analysis showed that adding ondansetron in morphine intravenous analgesia pump was an independent influencing factor of reduced postoperative nausea. The probability of nausea during the first post-operative day was 0.781 time(P=0.015)of that in the control group and 0.736 time(P=0.030)during the second post-operative day. Conclusion Adding ondansetron in morphine intravenous analgesia pump may reduce PONV in women.

OBJECTIVEThis study was aimed to investigate the effects of carbon monoxide releasing molecule (CORM-2), a novel carbon monoxide carrier, on the reendothelialization of carotid artery in rat endothelial denudation model.

METHODSMale rats subjected to carotid artery balloon injury were treated with CORM-2, inactive CORM-2 (iCORM-2) or dimethyl sulfoxide (DMSO). The reendothelialization capacity was evaluated by Evans Blue dye and the immunostaining with anti-CD31 antibody. The number of circulating endothelial progenitor cells (EPCs) was detected by flow cytometry. The proliferation, migration, and adhesion of human umbilical vein endothelial cells (HUVECs) were assessed by using [3H]thymidine, Boyden chamber and human fibronectin respectively. The expressions of protein were detected by using western blot analysis.

RESULTSCORM-2 remarkably accelerated the re-endothelialization 5 d later and inhibited neointima formation 28 d later. In addition, the number of peripheral EPCs significantly increased in CORM-2-treated rats than that in iCORM-2 or DMSO-treated rats after 5 d later. In vitro experiments, CORM-2 significantly enhanced the proliferation, migration and adhesion of HUVECs. The levels of Akt, eNOS phosphorylation, and NO generation in HUVECs were also much higher in CORM-2 treated group. Blocking of PI3K/Akt/eNOS signaling pathway markedly suppressed the enhanced migration and adhesion of HUVECs induced by CORM-2.

CONCLUSIONCORM-2 could promote endothelial repair, and inhibit neointima formation after carotid artery balloon injury, which might be associated with the function changes of HUVECs regulated by PI3K/Akt/eNOS pathway.

OBJECTIVETo investigate the efficacy of hematopoietic stem cell (HSC) transplantation via the hepatic artery vs. the portal vein for end-stage liver disease (ESLD).

METHODSPatients with hepatic decompensation were prospectively recruited from September 2010 to September 2012 to receive HSC transplantation via the hepatic artery or the portal vein. Liver function was examined at 3, 6, and 12 months after transplantation. Liver biopsy Results were analyzed using the Knodell score.

RESULTSEighty patients (58 males and 22 females) were enrolled in the study. The Child-Pugh score was grade B in 69 cases, and grade C in the remaining 11 cases. HSC transplantation was performed via the portal vein in 36 patients and via the hepatic artery in 44 patients. ALT levels decreased while serum albumin levels increased significantly in both groups at 6 and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Total bilirubin levels decreased significantly in both groups at 3, 6, and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Additionally, prothrombin time decreased in both groups at 12 months after HSC transplantation (P<0.05 compared with pre-transplantation level). There were no significant differences in ALT, total bilirubin and prothrombin time between the two groups either before or after transplantation. Moreover, Knodell score decreased significantly at 6 and 12 months. Histological examination showed that liver cell edema, degeneration, necrosis, and inflammation were significantly relieved at 3, 6, and 12 months after transplantation. The incidence of portal vein thrombosis, upper gastrointestinal bleeding, and hepatic encephalopathy were 1.25%, 3.75%, and 2.5% respectively. The one-year survival rate was 100%.

CONCLUSIONSAutologous HSC transplantation improves liver function and histology in ESLD patients. The administration route of HSC has no significant impact on the efficacy of transplantation.
