Objective:To study whether the glucose tolerance was impaired in the non-hyperglycemic rats treated with strepto-zotocin(STZ).Methods:Male SD rats,aged 10￣12 weeks,were divided into two groups:experimental group,with an intraperitoneal injection of 30 mg/kg(low dose)or 60 mg/kg(high dose)STZ;control group,with injection of equal dose acidified saline.1￣12 weeks after injection,the intraperitoneal glucose tolerance tes(tIPGTT)was performed in the non-hyperglycemic rats(fasting blood glucose

Neonatal hypoxic-ischemic brain damage (HIBD) is a complex disease process in which injury severity,duration and timing of the antenatal injury are difficult to discern.HIBD triggers a cascade of pathophysiological events (blood-brain barrier damage,oxidative stress,inflammation,glutamate excitotoxicity,energy depletion and cell death) leading to brain damage and neonatal death.Under this background,the changing of biomarkers in different types of biological fluids able to be detected and prognosed HIBD.

ObjectiveTo evaluate the efficacy of nerve stimulator-guided thoracic paravertebral block in patients undergoing segmental mastectomy.MethodsFifty ASA Ⅰ or Ⅱ female patients,aged 18-64 yr,with body mass index ＜ 24 kg/m2,undergoing segmental mastectomy,were randomly divided into 2 groups ( n =25 each):thoracic epidural block group (group A) and nerve stimulator-guided thoracic paravertebral block group (group B).In group A,an epidural catheter was placed at T3,4 interspace and 0.5％ ropivacaine 7-10 ml was administrated via the epidural catheter.In group B,thoracic paravertebral block was performed at T4 under the guide of the nerve stimulator and 0.5％ ropivacaine 25 ml was administrated.The perioperative adverse cardiovascular events (hypotension and bradycardia) were recorded.Shivering,chest distress,and dyspnea during operation and nausea and vomiting after operation were also recorded.The range of block on the operated side was determined by pinprick test.The efficacy of anesthesia was evaluated.ResultsThe incidence of shivering,chest distress,and dyspnea during operation and nausea and vomiting after operation was significantly lower in group B than in group A (P ＜ 0.05).Adverse cardiovascular events and respiratory depression were not found in the two groups.There was no significant difference in the range of block on the operated side in the two groups ( P ＞ 0.05).The satisfactory anesthesia was found in 100％ of cases.ConclusionNerve stimulator-guided thoracic paravertebral block can be safely and effectively used in patients undergoing segmental mastectomy and the efficacy is better than that of thoracic epidural block.

Objective To investigate the changes in pulmonary gas exchange and intrapulmonary shunting during orthotopic liver transplantation (OLT) without veno-venous bypass. Methods Sixteen ASA III-IV patients with end-stage liver diseases were studied. Anesthesia was induced with midazolam 0.1 mg ? kg-1 , fentanyl 10 ?g kg -1 , scopolamine 0.6 mg, and vecuronium 0.1 mg ? kg-1 and maintained with isoflurane and propofol infusion (2-3 mg? kg-1h-1 ) supplemented with intermittent iv boluses of midazolam, fentanyl and vecuronium. The patients were intubated and mechanically ventilated with 100% O2 Swan-Ganz catheter was inserted via right internal jugular vein. Radial artery was cannulated. MAP, HR, ECG, CVP, SpO2 and PET CO2 were continuously monitored. Body temperature was maintained at≥35.5℃ during operation. Blood samples were taken from radial and pulmonary artery for blood gas analysis. P(A-a) O2 and Qs/Qt were calculated immediately before operation (T1 ), cross-clamping (T2) and unclamping of inferior vena cava and portal vein (T3 ) , 5 min (T4) and 90 min (T5 ) after graft reperfusion and at the end of operation (T6). Results P(A-a) O2 and Qs/Qt were both higher than normal value at T1 . PaCO2, P(A-a) O2 and Qs/Qt increased significantly at T3 and T4 as compared with those at T2 P(A-a)O2 and Qs/Qt were significantly decreased at T5 and T6 as compared with those at T3 and T4 Qs/Qt was positively correlated with P(a-A) O2 and PAP. Conclusion There is a certain degree of intrapulmonary shunt before and during orthotopic liver transplantation without veno-venous bypass. The amount of fluid infused should be strictly controlled during anhepatic phase.

Objective To investigate the role of nursing intervention in the prevention of premature rupture of the membrane infection. Methods 131 patients with premature rupture of the membrane were divided into the control group(65 cases) and the experimental group(66 cases), they adopted routine nursing method and nursing intervention respectively. The duration of pregnancy, fetal condition and laboratory tests for infection were compared between two groups. Results No significant differences were found between the two groups in terms of age, duration of pregnancy, newborn weight. Significant differences were observed in Apgar score, newborn death between two groups. Conclusions Monitoring for signs of premature rupture of the membrane such as infection and laboratory tests are important for the prevention of infeclion, if infection occurs, delivery may be necessary to prevent further complications.

Objective Dickkopf-1 (DKK-1) is an antagonist of the Wnt signaling pathway of bone formation and it is the target gene of TNF.When DKK-1 is inhibited,osteoprotegerin (OPG) would increase,OPG can antagonize bone erosion caused by receptor activator of NF-κB ligand (RANKL).Detection the levelsof serum DKK-1,OPG,RANKL and TNF-α of patients with AS before and after applying TNF-α antagonist,the effects of anti-TNF-α treatment on signaling pathway of bone formation was explored.Methods Medical records and serum samples of 43 AS patients receiving TNF-α receptor-Ⅱ IgG Fc fusion protein for 12 weeks were collected and the levels of serum DKK-1,OPG,RANKL and TNF-α were detected by enzyme-linked immunosorbent assay.Paired t-test and Person's correlation analysis were used for data analysis.Results Disease activity indexes in AS patients with anti-TNF-α treatment,including VAS score,time of morning stiffness,BASDAI,BASFI,ESR and CRP,which were [(2.7±2.0) cm,(7±4) min,1.1±1.1,0.8±1.2,(10±9) mm/1 h and (16±26) mg/L] respectively,were reduced when compared with those before treatment,[(7.6±1.9) cm,(46±33) min,6.0±1.3,4.4±2.0,(39±29) mm/1 h and (76±43) mg/L] respectively,and the differences were statistically significant (P＜0.05).Serum levels of DKK-1,(3.3±1.5) μg/L vs (3.2±1.3) μg/L,OPG,(144±71) pg/ml vs (136±62) pg/ml,and RANKL,(71±37) pg/ml vs (68±30) pg/ml,were not changed (t=14.043,8.031,20.166,13.521,7.679,9.563,all P＞0.05).The levels of TNF-α increased from (1.9±1.3) pg/ml to (55.0±50.6) pg/ml (t=6.951,P＜0.05).There were no relations between DKK-1 and TNF-α,RANKUOPG,patient VAS,duration of morning stiffness,BASDAI,BASFI,ESR and CRP,allP＞0.05.Conclusion Clinical indicators are improved significantly by anti-TNF-α therapy; however,it should not be withdrawal suddenly.There is no relationship between serum levels of DKK-1 and level of inflammation in AS patients.
