Objective: To investigate the effects of dexmedetomidine (DEX) on oxidative stress and systemic inflammatory response syndrome(SIRS) during cardiopulmonary bypass (CPB).Methods: Totally 62 patients scheduled for mitral valve replacement surgery were enrolled in this study and randomly assigned to DEX group with constant infusion of DEX (0.5 μg·kg-1 ·h-1 , n =31) and the control group with the same amount of 0.9% sodium chloride injection(n =31).A volume of 4 ml of jugular vein blood was respectively withdrawn before the induction of anesthesia (T0), at 10 min after aortic-off clamping(T1), the end of bypass(T2), 4h after bypass(T3),12h after bypass(T4) and 24h after bypass(T5).The serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6(IL-6), interleukin-8(IL-8) and interleukin-10(IL-10) were determined.Results: The serum CRP in both groups increased remarkably at T1-T5 , while the serum CRP in DEX group was significantly lower than those in the control group at T3-T5.The serum TNF-α increased remarkably in control group at T2-T4, while the serum TNF-α increased remarkably in DEX group at T2-T3;the serum TNF-α in DEX group was significantly lower than those in the control group at T3-T4.The serum IL-6, IL-8, IL-10 in both groups were increased remarkably at T2-T5, T1-T5,T1-T3, respectively.The serum IL-6 and IL-8 in the DEX group were significantly lower than those in the control group at T2-T4 while the serum IL-10 in the DEX group was significantly higher than that in the control group at T1-T3.The serum WBC in both groups at T3-T5 were higher than those at T0, while the serum WBC in the control group was significantly higher than that in the DEX group at T3-T5.However, the differences between the two groups at mechanical ventilation time, ICU observation time, the incidence of postoperative SIRS after 24h, hospitalization days, and the adverse reactions were not statistically significant.Conclusion: DEX has notable protective effects on systemic inflammatory response syndrome during extracorporeal circulation.

Objective To investigate the expression changes of nuclear factor-kappa B(NF-kB) and intercellular adhesion molecule-1(ICAM-1)in rats with severe acute pancreatitis(SAP)and the effect of pretreatment of pioglitazone,a specific peroxisome proliferator-activated receptor?(PPAR?),)ligand, on the development of SAP.Methods Fifty-four SD rats were divided into sham operation group(C), SAP group(A)and pioglitazone pretreatment group(Ⅰ).The SAP was induced by retrograde infusion of 5% sodium taurocholate(0.1 ml/100 g)into the biliopancreatic duct.The rats inⅠgroup were intraperi- toneally injected with pioglitazone(2 mg/100 g)two hours before operation.The rats were sacrificed at 3,6 and 12 hrs,the blood,ascites and pancreatic tissues were collected(6 rats once for each group). The expressions of NF-kB and ICAM-1 in pancreatic tissues were measured by immunochemistry,mean- while the serum amylase,the amount of ascitic,pancreatic wet/dry ratio were measured.The pathologi- cal changes of pancreatic tissues were observed by immunochemistry staining with hematoxylin and eosin and the score of the tissues were evaluated.Results Pretreatment with pioglitazone could significantly attenuated the severity of SAP,including reduction of amylase and ascites,and the mass and pathological scores of the pancreatic tissue were decreased after 6 hrs of medication.The expression of ICAM-1 and NF-kB activity were inhibited.Conclusions Above findings demonstrate that pioglitazone can attenuate the severity of SAP by inhibition of ICAM-1 expression and NF-kB activation.The beneficial effects of pioglitazone might be due to its anti-inflammatory activities.The pioglitazone can be used as a new drug in treatment of SAP.

Objective To explore the three criteria of Ranson,CT severity index (CTSI) and the bedside index of severity in acute pancreatitis (BISAP) in assessment of severity and prognosis of acute pancreatitis.Methods A total of 503 diagnosed acute pancreatitis patients from January 2008 to April 2011 were studied retrospectively,including 356 mild acute pancreatitis (MAP) cases and 147 severe acute pancreatitis (SAP) cases.The differences of the three criteria of Rason,CTSI and BISAP in assessment of severity and prognosis of acute pancreatitis were compared with receiver operating characteristic (ROC) curve.The SAP group was divided into no organ failure group and organ failure group,and the predictive value of the three criteria in acute pancreatitis with organ failure was compared.Results There was significant differences between MAP group and SAP group with Rason,CTSI and BISAP score (x2 =236.88、126.24 and 101.27,P＜0.01).The sensitivity (97.3％) and AUC value (0.93) of Ranson criterion was highest.In no organ failure group and organ failure group of 147 SAP patients,there was significant difference between Ranson criterion and BISAP criterion (x2 =17.67 and 26.12,P＜0.01),both sensitivity were 100％,the specificity were 96％ and 85％ respectively,and the area under ROC curve (AUC) value of BISAP criterion (0.8) was the highest.In illness improved group and deteriorated group,the difference of score between Ranson criterion and BISAP criterion was significant (x2 ＝ 9.53 and 10.19,P＜0.05),and the AUC value of BISAP criterion (0.74) was the highest.Conclusions All three criteria can be used to determine the severity of acute pancreatitis.In predicting the risk of SAP with organ failure and prognosis,BISAP criterion is better than Ranson criterion.BISAP criterion is simple and easy to practice,which provides an important rule for evaluating the clinical condition of acute pancreatitis.

Abstract: To report the diagnosis, treatment and outcome of 4 patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection in the Second Affiliated Hospital of Kunming Medical University, further clarify the importance of blood culture and deepen the clinical understanding of the disease. Four patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection treated in the Second Affiliated Hospital of Kunming Medical University from 2017 to 2021 were recruited as the study objects. The clinical manifestations, blood culture collection, detection time of Aeromonas hydrophila, laboratory examination, treatment and prognosis of the patients were retrospectively analyzed. In this study, 4 cases were male patients with hematological diseases, who were in myelosuppression after chemotherapy. After fever, blood culture was collected and Aeromonas hydrophila was detected. The positive time of blood culture in 4 cases ranged from 4 to 11 hours. The results of antibiotic sensitivity showed that it was highly sensitive to the second, third and fourth generation cephalosporins, quinolones and carbapenems. Four patients were treated with imipenem cilastatin sodium in the early stage, and one patient recovered after active anti infection and leukocyte raising treatment. One patient did not complete chemotherapy due to a request for discharged, and the follow-up was unknown. Two patients developed rapidly into necrotizing fasciitis and died later. Hematological diseases complicated with Aeromonas hydrophila bloodstream infection are rare, but the mortality rate is high. For patients with repeated fever and considering infection, blood culture should be carried out as soon as possible to confirm the pathogen and drug sensitivity test. During clinical treatment, the treatment should be adjusted in time in combination with the patient's situation. In addition to anti-infection treatment, the patient's immunity should be improved and the development of necrotizing fasciitis should be vigilant.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

Obgective To explore the antimicrobial resistance genotypes and molecular epidemic features of Klebsiella pneumoniae (K.pneumoniae) producing extended spectrum 3-lactamases (ESBLs) in the Pediatric Intensive Care Unit (PICU) of Guiyang Children' s Hospital.Methods Disc diffusion technique (Kirby-Bauer method) and automatic microbiology analysis system were employed to determine the antimicrobial resistance,and Double-disk Diffusion was adopted in the phenotype confirmatory test of ESBLs,and PCR was used to determine the antimicrobial resistance genotypes.Results Among 44 straits of non-repetitive-K.pneumoniae,isolated from the children during hospitalization since April to December of 2013,29 straits (65.9％) were detected.The findings of sensitivity tests showed that 29 strains of ESBLs-producing K.pneumoniae presented a higher rate of sensitivity to carbapenems,cephamycin and quinolones,100％ resistance to penicillin and cephalosporins of the first and the second generations.Fifteen non-ESBLs-producing K.pneumoniae presented 100％ resistance to penicillin.The rate of resistance to 9 kinds of antibiotics (Ampicillin/Sulbactam,Cefazolin,Cefuroxime,Cefamandole,Cefiriaxone,Ceftazidime,Cefepime,Gentamicin,Aztreonam) in ESBLs-producing K.pneumoniae strains(79.3％,100.0％,100.0％,100.0％,100.0％,79.3％,65.5％,41.4％,79.3％) was significantly higher than that of non-ESBLs-producing K.pneumoniae trains (13.3％,6.7％,20.0％,20.0％,0,0,0,6.7％,0) (x2 =17.54,35.51,28.00,28.00,44.00,24.93,17.30,4.18,24.93,all P ＜ 0.05).In 29 strains of ESBLs-producing K.pneumoniae,3 genotypes were detected respectively:93.1％ of SHV (27/29 strains),51.7 ％ of TEM (15/29 strains) and 37.9 ％ of CTX-M (11/29 strains).Five forms of genotype distribution were presented:14 (43.8％) strains carrying single ESBLs gene,5 (17.2％) strains carrying 2 types,19 (31.0％) strains carrying 3 types,and 1 strain had not been genotyped.Conclusions ESBLs-producing K.pneumoniae had been epidemic in PICU of Guiyang Children's Hospital,with multiple antimicrobial resistances and diversification of antimicrobial resistance genotypes.

Objective To investigate the risk factors for prognosis of severe acute pancreatitis (SAP).Methods The clinical data of 563 patients with acute pancreatitis (AP) treated from January 2008 to December 2014 were analyzed retrospectively.There were 334 patients with mild acute pancreatitis (MAP),and 198 patients with moderately severe acute pancreatitis (MSAP),and 31 patients with severe acute pancreatitis (SAP).Risk factors associated with MAP and MSAP + SAP group,MSAP and SAP group were determined by univariate logistic regression,and multivariate analysis was used to determine the risk factors for severity of AP.Results Univariate logistic regression analysis showed that age,WBC,serum glucose,calcium,urea nitrogen arterial partial pressure of oxygen (PaO2),SIRS,pleural effusion,peripancreatic fluid collection were associated with severity of AP in MAP and MSAP + SAP patients;age,serum calcium,PaO2,SIRS,pleural effusion,peripancreatic fluid collection were associated with severity of AP in MSAP and SAP patients.Multivariate logistic regression analysis showed that age,serum calcium,PaO2 and peripancreatic fluid collection were risk factor of MSAP and SAP;age,serum calcimm and SIRS were risk factors of SAP patients for persistent organ failure and pancreatic necrosis.Conclusions For elderly AP patients,measurement of arterial partial pressure of oxygen and serum calcium,peripancreatic fluid collection can help evaluate the severity of AP and early recognition.For SAP patients,the presence of SIRS,high serum urea nitrogen,and low serum calcium and peripancreatic fluid collection raise the concerns of persistent organ failure and pancreatic necrosis.
