Objective:To investigate the influence of gender difference on the activation of platelets in septic rats.Methods: Totally 20 female and 20 male SD rats were randomly divided into four groups: male sham-operated group,female sham-operated group,female septic group,and male septic group,with each group containing 10 rats.Sepsis model in the last two groups was produced by cecal ligation and puncture(CLP);rats in the sham-operated group received no CLP.The rats were sacrificed 24 hours after surgery;the blood samples were collected for blood routine test;and the serum ?-TG levels were detected by ELISA assay.Serum estrogen(E2) levels were detected by radioimmunoassay.Results: The blood platelet counts were decreased in both septic rats of both genders;the count in female rats was significantly higher than in the male rats(P

Objective To compare the QTc and QTcd between type 2 diabetic and non-diabetic patients with post-myocardial infarction (post-MI) ,and to compare the QTcd in type 2 diabetic patients with post-MI treated with insulin,sulfonylurea,mefformin,or diet alone. Methods We measured the QTc and QTcd through simultaneous 12-lead Electrocardiogram in 138 post-MI patients,including 70 type 2 diabetic (of which,23 were assigned to re-ceive insulin,20 glipizide,16 mefformin,11 diet control) and 68 non-diabetic patients. Result Compared with post-MI patients without diabetes,those with type 2 diabetes had significantly higher QTc [(377.2±24.3) ms vs (342.9±27.5)ms,t=7.79,P<0.01] and QTcd [(48.8±19.7)ms vs (40.3±26.6)ms,t=2.14,P<0.05]. There were no significant difference between the mefformin group and the diet control group (P>0.05). The QTc and QTcd in the insulin group were significantly higher than those in the other three group s(P<0.05),and the QTc and QTcd in the glipizide group were higher than those in the mefformin group or diet control group(P<0.05,and P<0.01,respectively). Conclusion Type 2 diabetes is associated with an additional increase in the QTcd in post-MI patients,suggesting higher mortality risk in post-MI patients with type 2 diabetes. Insulin and glipizide may in-crease the QTc and QTcd in post-MI patients with diabetes. These effects were more significant in the insulin therapy group.

Objective To clone NT-3 gene from normal rat brain and to purify its fusion protein and to prepare specific high titer antibody so that to provide a foundation for further study for peripheral nerve injury.MethodsWe amplified target gene by RT-PCR and cloned it into the vector of pMD-18T,then analyzed its sequence and compared it with the sequence from GenBank.We subcloned it into pRSET-A vector and introduced it into Escherichia coli BL21.The expression was induced by IPTG,and identified by SDS-PAGE.The fusion protein was purified by niccolum purify kit.We immuned rabbits with immunological adjuvant for specificity antibody preparation.Results We got a 777 bp gene segment by RT-PCR.The DNA sequence was identical to rat NT-3 gene sequence in GenBank.It proved that the target gene was correctly inserted into the vector.A new protein band of about 34 ku appeared on SDS-PAGE after induction of IPTG.A specific high titer antibody of 1∶64000 was gained by immunizing rabbits with adjuvant.

Objective:To explore the application effect of "sandwich" teaching in the standardized residency training of blood purification center.Methods:A total of 72 residents who participated the standardized residency training of blood purification center of The Third Hospital of Mianyang from July 2019 to November 2019 and December 2019 to April 2020 were selected to be divided into control group and research group in average. The control group used traditional teaching and the research group took "sandwich" teaching, respectively. The two groups of subject assessment results and post competency before and after the teaching were compared. SPSS 23.0 software was used for t test and chi square test. Results:The research group's academic knowledge test scores and practical operation skills test scores were (91.64±5.38) points and (86.81±5.30) points respectively, and those in the control group were (84.25±5.26) points and (78.28±5.07) points respectively, and the scores in the study group were higher than those in the control group ( P<0.05). After teaching, the assessment scores of personal quality, professional knowledge, professional skills, professional ability and self-concept of the research group were (18.61±2.38) points, (18.28±2.29) points, (17.56±2.20) points, (18.81±2.41) points and (17.75±2.34) points respectively, and those in the control group were (16.42±2.19) points, (15.81±2.37) points, (15.06±2.41) points, (16.31±2.35) points and (15.31±2.28) points respectively. All above scores of the two groups after teaching were higher than those before teaching ( P<0.05), and those of the research group after teaching were higher than those of the control group ( P<0.05). Conclusion:"Sandwich" teaching can improve the examination results and post competency of the residents during the standardized residency training of the blood purification center.

ObjectiveTo investigate the effectiveness and safety of nanoknife ablation guided by real-time virtual sonography (RVS) in the treatment of locally advanced pancreatic cancer (LAPC). MethodsA retrospective analysis was performed for the clinical data of 27 patients with LAPC who attended The Fifth Affiliated Hospital of Zhengzhou University from April 2018 to October 2019, and according to the treatment method, the patients were divided into combination group (12 patients treated with IRE combined with chemotherapy) and control group (15 patients treated with chemotherapy alone). The chemotherapy regimen was gemcitabine combined with tegafur, gimeracil and oteracil potassium for both groups. Adverse reactions and complications were observed for the combination group during the perioperative period, and the two groups were compared in terms of the changes in myocardial enzymes, blood amylase, and carbohydrate antigen 19-9 (CA19-9) before treatment and at different time points after treatment, as well as remission rate (RR) and disease control rate (DCR) at 3 months after treatment and survival status during follow-up. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups, and the Wilcoxon test was used for comparison within each group; the Fisher’s exact test was used for comparison of categorical data between groups; the Kaplan-Meier method was used to analyze the survival status during follow-up. ResultsIn the combination group, there were 12 cases of adverse reactions and mild complications during the perioperative period, i.e., 9 Clavien-Dindo grade I cases and 3 grade II cases. All patients in the combination group experienced a transient increase in myocardial enzymes, which returned to normal within 7 days, and there were no significant changes in creatine kinase and lactate dehydrogenase on day 7 after treatment (P＞0.05); 9 patients had a significant increase in blood amylase on day 1 after surgery, which significantly decreased on day 7 after surgery and basically returned to normal on day 14 after surgery, and there was no significant change in blood amylase on days 7、14， and 1 month after surgery (P＞0.05). Before treatment, the level of CA19-9 was higher than the normal value in both groups, and the combination group had a significant reduction in CA19-9 at 1, 2, and 3 months after treatment (all P＜005); in the control group, the level of CA19-9 firstly decreased for a short time and then increased, while there was no significant change in CA19-9 at 1, 2, and 3 months after treatment (all P＞0.05). At 3 months after treatment, the combination group had significantly higher RR and DCR than the control group (RR: 75.0% vs 26.7%, P=0.021; DCR: 91.6% vs 53.3%, P=0043). During the median follow-up time of 13 months, compared with the control group, the combination group had significantly higher median progression-free survival time (10 months vs 5 months, P=0.014) and median overall survival time (18 months vs 10 months, P=0.034). ConclusionRVS-guided percutaneous nanoknife ablation has marked clinical effect and high safety in the treatment of LAPC and can be used as a new treatment option for patients who refuse or cannot tolerate laparotomy for ablation therapy.

Objective To compare the effect of dexmedetomidine combined with butorphanol to prevent the adverse effects of carboprost tromethamine druing cesarean delivery.Methods Ninety parturients with the risk factor of uterine atony,aged 24-40 years,weighting 55-85 kg,ASA physical status Ⅰ or Ⅱ,undergoing full term cesarean section,were randomly divided into dexmedetomidine combined with butorphanol group (group DB,n=30),butorphanol group (group B,n=30)and control group (group N,n=30).Three groups were intravenously injected corresponding drugs of carboprost tromethamine into uterus.Group DB was given intravenous injection dexmedetomidine 1 μg/kg combined with butorphanol 20 mg/kg.Group B was given butorphanol 20 mg/kg.Group N was given 0.9% sodium chloride solution.MAP,HR,and SpO2were recorded at different times,10 min after go into operation room (T0),10 min after carboprost tromethamine into uterus (T1),end of operation (T2).Ramsay sedation score was recorded at T1.The adverse effects of carboprost tromethamine were recorded.The initial time of lactation after operation was recorded.The initial time of lactation after operation,the height of uterine fundus at 1,3,5 d after operation,the oxyto-cin doses within 72 h after operation were recorded.Results Compared with group N,the MAP and HR of group DB and group B decreased obviously at T1(P<0.05),and group DB was lower than group B obviously at T1(P<0.05).Compared with group N,the scores of Ramsay in group DB and group B were significantly higher (P<0.05),group DB was higher than that of group B(P<0.05). Compared with group N,the incidence of nausea,vomiting,chest tightness,chest pain,hyperten-sion,tachycardia and chills in group B and group DB were significantly lower (P<0.05),and group DB was lower than that of group B (P<0.05).There were no significant differences of the initial time of lactation after operation,height of uterine fundus at 1,3,5 d after operation,the oxytoxin doses within 72 h after operation between the three groups.Conclusion Dexmedetomidine combined with butorphanol can effectively reduce the adverse effects of carboprost tromethamine druing cesarean delivery,the more stable hemodynamics and sedative effect,the effect is better than the sin-gle application of butorphanol,at the same time does not affect lactation,it is safe and effective for clinical use.
