Objective To investigate the relationship between leptin level of IGR patients and intima-media thickness (IMT) of carotid arterial. Methods One hundred and eighteen IGR patents were enrolled into the following three groups according to the result of oral glucose tolerance test (OGTT): 38 cases of the purely impaired fasting glucose (IFG) group, 42 cases of the purely impaired glucose tolerance (IGT) group and 42 cases of the IFG combining with IGT (IFG + IGT) group. Thirty-eight cases with normol glucose tolerance (NGR) were enrolled in the NGR group. The blood fat, fasting blood-glucose (FBG), fasting insulin (insulin), fasting C peptide , 2 h-postprandial blood glucose , 2 h-insulin , 2 h-C peptide , glycosylated hemoglobin (HbA1C), C-reactive protein (CRP), body mass index (BMI), leptin and IMT were determined in patients of the three groups and the healthy controls. The multiple linear regression was used to analyze the relationship between leptin level and IMT , and person correlation was further used to analyze the affinity degree between leptin level and IMT. Results Compared with the NGT group, the inter-group comparison showed that leptin level was significantly increased in the IFG, IGT and (IFG + IGT) groups (P < 0.05, respectively). Compared with the IFG and IGT groups, IMT and the leptin level were increased in the (IFG + IGT) group (P < 0.05, respectively). The multiple linear regression analysis showed that leptin level was correlated with the increase of IMT in the (IFG + IGT) group (P < 0.05), but not in the IFT group and the IGT group. Conclusion The leptin level in the IGR group and the IMT in the IFG + IGT ) group were significantly increased , the leptin level was closely associated with IMT.

Objective To investigate the effects of sevoflurane and propofol on postoperative cognitive function after abdominal surgery for elderly patients with diabetes. Methods Seventy diabetic patients (aged 60~75 yr, ASAⅠorⅡ) underwent abdominal surgery and are included in the research. Diabetic patients were randomly divided into two groups (n=35): sevoflurane group(group DS) and propofol group (group DP). MMSE score, the attachment test, words memory test and Stroop color word test were carried and the results were recorded before operation (T1), postoperative 24 h (T2), 48 h (T3) and 1 w (T4). Results Compared with T1, patients′ MMSE score reduced at T2 and T3. Time spent in attachment test is longer at T2 and T3. Mistaken incidences in Stroop color words test 1, 2 and 3 are higher and time longer at T2. Time spent on Stroop color words test 2 and 3 is longer in T3. Words memory test reveals decline at T2 and T3, whose difference is statistically significant (P < 0.05). Cognitive dysfunction incidence in the two groups shows no statistical significance (P > 0.05). Conclusion Sevoflurane and propofol can result in postoperative cognitive dysfunction for elderly patients with diabetes within 48 h after abdominal surgery, there were no difference between the effects of them.

Objective To investigate the nursing points of pancreatic leakage after upper abdominal multiple organ transplantation. Methods A retrospective study was conducted on the nursing experience of two patients with end-stage liver disease and type 2 diabetes mellitus who were complicated with pancreatic leakage after upper abdominal multiple organ transplantation from March 2009 to July 2015. Results The blood glucose of these patients returned to normal level within 1 week after operation and insulin was discontinued. Pancreatic leakage was occurred in the two patients at 14 and 21 days after operation, respectively. They were both successfully discharged after active treatments and nursing cares including completely drainage, the application of drugs that inhibited the secretion of pancreatic enzymes and digestive tract glands, strengthening infection control, nutritional support and other conservative treatments. Conclusions It is the key to improve the recovery of pancreatic leakage after upper abdominal multiple organ transplantation with careful observation of abdominal signs and abdominal drainage tube, accurate use of somatostatin, nutritional support, maintenance of water and electrolyte balance, and psychological intervention.

Objective To observe the effect of acute normovolemic hemodilution(ANH)combined with enhanced recovery after surgery(ERAS)on immune function in patients undergoing hepatic lobectomy. Methods 80 patients were divided into two groups:ERAS group(group E),ANH combined with ERAS group(group AE). bleeding volume,blood transfusion,infused fluid volume,urine output during operation and clinical index after surgery were recorded. Exhaust and defecation time ,fluid intake time and hospitalization duration were also record-ed. Blood samples were obtained from the patients at 30 min before anesthesia induction(T1),immediately(T2), 24 h(T3),3 d(T4)and 7 d(T5)after the end of operation for determination of the expression of CD3+,CD4+, CD8+ on T cells and natural killer cell. Results In group E ,CD3+,CD4+ T-lymphocytes and NK cells at T2-3 decreased as compared with T0. Compared with group E ,no allogeneic blood transfusion cases were found and clinical index duration was shorter in group AE. CD3+,CD4+T-lymphocytes and NK cells at T2-3 increased in group AE as compared with those in Group E. The difference is significant (P < 0.05). Conclusion ANH combined with ERAS can decrease allogenic blood transfusion and increase post-operation immunologic function ,shorten the postoperative hospitalization time.

Objective To evaluate the effect of ultrasound-guided transverse abdominal plane block (TAPB) on postoperative analgesia in patients undergoing orthotopic liver transplantation under general anesthesia.Methods Forty American Society of Anesthesiologists physical status Ⅲ-V patients,with body mass index of 18-24 kg/m2,aged 18-64 yr,undergoing elective modified piggy-back orthotopic liver transplantation,were divided into 2 groups (n =20 each) by a random number table method:TAPB combined with general anesthesia group (TAPB-GA group) and general anesthesia group (GA group).In TAPB-GA group,two-point TAPB was performed below bilateral costal margins under ultrasound guidance after induction of general anesthesia,and a mixture of 0.33％ ropivacaine 15 ml plus 0.5％ dexamethasone 0.5 ml was injected into each point.The equal volume of normal saline was injected into each point instead in group GA.Patient-controlled intravenous analgesia was performed with sufentanil 2 μg/kg after operation in both groups.Sufentanil 5 μg was intravenously injected as rescue analgesic,and the visual analog scale score was mainrained ≤3 within 48 h after operation.The intraoperative consumption of remifentanil and extubation time after operation were recorded.The requirement for sufentanil as rescue analgesic and development of nausea and vomiting,itching and respiratory depression were recorded within 48 h after surgery.Results Compared with group GA,the intraoperative consumption of remifentanil and requirement for sufentanil as rescue analgesic within 48 h after surgery were significantly reduced,the time of extubation was shortened,and the incidence of nausea and vomiting,itching and respiratory depression was decreased in group TAPB-GA (P＜ 0.05).Conclusion Ultrasound-guided TAPB can provide better efficacy of postoperative analgesia with fewer adverse reactions in patients undergoing orthotopic liver transplantation under general anesthesia.

Objective To observe the protective effect of dexmedetomidine(Dex)at different doses com-bined with ulinastatin in lung resection patients with one lung ventilation. Methods 80 patients having undergone unilateral lung resection were divided into four groups randomly:control group(C group)and groups Dex 1-3,20 cases in each group.One lung ventilation(OLV)was used in all the groups during operation.The patients in groups Dex 1-3 were treated with 0.5,1.0,2.0 μg/kg combined with ulinastatin,and the C group with amount of normal sa-line instead.The comparisons were done among the four groups in terms of SOD,L-6,IL-10,serum malondialde-hyde(MDA)concentration at 5 min after endotracheal intubation(T0),30 min(T1),60 min(T2),120 min (T3)as well as the levels of FVC,FEVl and FEVl/FVC at 24 h,48 h and 72 h after surgery. Results In the groups C and Dex 1,SOD decreased at T1-4 and IL-6,MDA and IL-10 at T2-4 rose.SOD decreased at T2-4 in groups Dex 2-3 and MDA,IL-6 and IL-10 rose.Compared with group C,the levels of SOD and IL-10 at T2-4 in groups Dex 1-2 and at T1-4 in group Dex 3 rose. In groups Dex 1-3,postoperative FVC,FEVl and FEVl/FVC rose.Compared with group Dex 1 or 2 respectively,SOD and IL-10 at T2-4 in group Dex 3 significantly rose,but MDA and IL-6 significantly declined;FVC,FEVl and FEVl/FVC significantly rose 48 h and 72 h after surgery (P<0.05). Conclusion Dex combined with ulinastatin has a protective effect for patients with one lung ventila-tion after lung resection,with the best-suggested dose of 1.0 μg/kg.

Objective To evaluate the efficacy of ultrasound-guided anterior quadratus lumborum block combined with general anesthesia for laparoscopic radical resection of rectal carcinoma. Methods A total of 80 patients of both sexes, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 40-64 yr, scheduled for elective laparoscopic radical resection of rectal carcinoma, were divided into 2 groups ( n=40 each) using a random number table method: anterior quadratus lumborum block combined with general anesthesia group ( group QG) and general anesthesia group ( group G) . In group QG, anteri-or quadratus lumborum block was performed with 0. 33％ ropivacaine 25 ml and dexamethasone 5 mg under ultrasound guidance before operation, and the same procedure was performed on the other side. Combined intravenous-inhalational anesthesia was applied, propofol 3-5μg∕ml and remifentanil 3-5 ng∕ml were given by target-controlled infusion, and cisatracurium was intermittently injected in two groups. Patient-controlled intravenous analgesia with sufentanil 2μg∕kg was used for postoperative analgesia. The analgesic pump was set up to deliver a 2 ml bolus dose with a 15-min lockout interval. Bruggrmann comfort scale ( BCS) scores were recorded at 1, 6, 12, 24 and 48 h after operation ( T1-5 ) . Tramadol was used for rescue analgesic after operation. The consumption of remifentanil and sufentanil, requirement for tramadol, occurrence of adverse reactions and patients' satisfaction with postoperative analgesia were recorded. The emergence time, first ambulation time, time to first flatus∕poo and length of hospital stay were also recorded. The develop-ment of anterior quadratus lumborum block-related complications was recorded. Results Compared with group G, BCS scores were significantly increased at T4,5 , the consumption of remifentanil, requirement for tramadol and incidence of nausea and vomiting were decreased, patients' satisfaction with postoperative an-algesia was increased, and the emergence time, first ambulation time, time to first flatus∕poo and length of hospital stay were shortened in group QG (P<0. 05). Conclusion Ultrasound-guided anterior quadratus lumborum block combined with general anesthesia can reduce the consumption of opioids in the perioperative period and is helpful in improving outcomes when used for laparoscopic radical resection of rectal carcinoma.

Objective:To explore the effect of personalized psychological intervention based upon acceptance and commitment therapy on paternal donors and spouses after pediatric liver transplantation.Methods:From July 2017 to November 2019, a total of 160 parental donors and spouses undergoing pediatric liver transplantation were selected as research objects.Through a random number table, 40 donors and 40 liver donor spouses were assigned into control and experimental groups.The control group received routine psychological intervention while the experimental group had personalized psychological intervention with acceptance and commitment therapy based upon conventional psychological intervention.Symptom checklist-90, numeric rating scale, chronic pain acceptance questionnaire-8, length of stay, hospitalization cost, complication rate, initial postoperative ambulation time and hospital satisfaction were employed as evaluation tools.Results:After interventions, SCL-90 score, pain assessment score and initial ambulation time of donor group were significantly lower than those of control group( P<0.05). Hospitalization satisfaction and chronic pain acceptance were significantly higher than those of control group( P<0.05). SCL-90 score was significantly lower in liver spouse observation group than that in control group and hospitalization satisfaction higher than control group( P<0.05). Conclusions:Personalized psychological intervention based upon acceptance and commitment therapy can help parental donors and spouses to improve their mental health, help donors to recover sooner and boost hospitalization satisfaction.

BackgroundNurses' moral courage is a special type of altruistic behavior， which is considered to be a key factor to improve patient safety. Empathy level can positively predict altruistic behavior， and moral sensitivity exerts an obvious mediation role in the positive prediction. At present， there is no relevant research to explore the path role of moral sensitivity in the relationship between empathy and moral courage. ObjectiveTo verify the mediation role of moral sensitivity in the relationship between empathy and moral courage among nursing students， so as to provide references for increasing the moral courage among nursing students. MethodsFrom June 1 to June 30， 2022， a total of 602 nursing students were recruited via convenience sampling from a tertiary grade A hospital in Mianyang， and participants were assessed using Interpersonal Reactivity Index-Chinese （IRI-C）， Moral Sensitivity Questionnaire-Revised Chinese Version （MSQ-R-CV） and Nurses' Moral Courage Scale （NMCS）. Pearson correlation analysis was used to assess the correlation among above scales. The Process macro plug-in for SPSS was used to test the mediation effect of moral sensitivity on the relationship between empathy and moral courage. ResultsA total of 602 valid questionnaires were collected， with an effective recovery rate of 96.78%. IRI-C score of nursing students was positively correlated with MSQ-R-CV score and NMCS score （r=0.269， 0.146， P<0.01）. MSQ-R-CV score was positively correlated with NMCS score （r=0.722， P<0.01）. The mediation effect model was established with IRI-C score as independent variable， MSQ-R-CV score as intermediary variable， and NMCS score as dependent variable. Analysis showed that the direct effect of empathy on moral courage among nursing students was not significant （direct effect value of -0.052， 95% CI： -0.178~0.008）， while analysis yielded a significant indirect effect of empathy on moral courage via moral sensitivity （indirect effect value of 0.189， 95% CI： 0.209~0.407）. ConclusionThe moral sensitivity of nursing students plays a significant mediation role in the relationship between empathy and moral courage. ［Funded by 2022 Higher Education Teaching Research and Reform Project of Southwest Medical University （number， JG2022239）］
