Objective To investigate the effects of epidural anesthesia on blood glucose and hemodynamics in patients undergoing gynecological laparoscopic surgery .Methods 108 cases undergoing laparoscopic gynecology surgery in our hospital from January 2012 to January 2014 were randomized into the observation group and control group equally .The observation group was treated by epidural anesthesia for surgery , while the control group was trea-ted by general anesthesia .The hemodynamics and blood glucose in the two groups were compared before anesthesia , after pneumoperitoneum and surgery .The operative time , blood loss during operation , volume of fluid infusion and pneumoperitoneum time were recorded .Results The operative time , blood loss during operation , volume of fluid in-fusion and pneumoperitoneum time had no significant differences between the two groups (p>0.05).The heart rate in the observation group was significantly higher than that in the control group at the time point of 5 min after pneumo-peritoneum.The blood pressure in the observation group was significantly lower than that before anesthesia at the time of 30 min after pneumoperitoneum , as well asafter operation .Theblood pressure after pneumoperitoneum in the control group was significantly higher than that before anesthesia , with DBP after operation higher than that before anesthesia (p<0.05).Postoperative blood glucose in the control group was significantly higher than that before anesthesia (p<0.05).Both systolic blood pressure and diastolic blood pressure in the observation group after pneumoperitoneum and operationwere significantly lower than thosein the control group (p <0.05).Conclusion Epidural anesthesia is more ideal to reduce stressresponse ,control blood pressure , and maintainnormal blood sugar levels .

To analyze clinical, neuro-electrophysiologocal, imaging and pathological characteristics of Hirayama disease (HD) and review its relevant literatures to improve its diagnosis. Clinical data of two HD cases admitted to Fujian Provincial Hospital, Fuzhou during 2005 to 2008 were analyzed with literatures review. HD occurred more in males, often onset at their adolescence with muscular weakness and atrophy in one or two upper limbs, but without sensory dysfunction or pyramidal signs. Neuro-electrophysiology showed neurogenic abnormality in the body areas dominated by the 4th cervical vertebra to the 1 st thoracic vertebral (C4-T1) spinal nerves in all the patients. Magnetic resonance imaging (MRI) showed slight atrophy of the lower cervical spinal cord at routine position and its compression and forward displacement to varied extent at flexion position, with posterior epidural capsular space widening, crescent or striped high signal, and voids of vessels in some patients. Enhancement magnetic resonance scanning showed crescent sign enhanced in some patients. Biopsies of the inflicted muscles appeared slight neurogenic abnormality in some cases, and normal in other cases. HD is rarely seen clinically, but it can usually be diagnosed according to its symptoms, neuro-electrophysiology and MRI.

Objectives To explore the relativity between Alzheimer ’ s disease ( AD)-like lesions and metabolic syndrome models induced by high-sugar high-fat diet in rats.Methods Forty-eight Sprague Dawley rats were randomly divided into 2 groups.The control group (fed with normal diet, 12 rats) and high sugar and high fat group (fed with high-sucrose and high-fat diet, 12 rats) continuously for 12 months.At the end of 6, 9 and 12 months of the experiment , we observed the animal body weight and visceral fat weight .The blood lipid levels , blood glucose and MS-related biochemical parameters were determined . The brain tissues were examined by histopathology . The characteristic AD molecules hippocampus Aβand Tau were detected using ELISA and Western blotting to confirm the presence of AD lesions in the brain.Results Compared with the normal control group , the body weight and visceral fat weight of the rats in the high-sugar high-fat groups were significantly increased; the levels of TG , FPG, LDL, HOMA-IR and hippocampus Aβ,phosphorylated Tau (p-Tau) were higher, but the level of HDL was decreased (P<0.05 for all).The histopathological examination revealed inflammatory cell infiltration in the brain tissues .Conclusions Characteristic AD-like lesions may occur and accompany the rat models of metabolic syndrome , induced by high-sugar high-fat diet, and provide a new idea for the construction of Alzheimer ’ s disease animal models .

Objective To investigate the clinical values of multiple ultrasound soft markers in screening for fetal chromosomal abnormality during first-trimester.Methods Two thousand seven hundred and eighty-nine nulliparas in Department of Obstetrics,the First Affiliated Hospital of Jinan University during early pregnancy (11-13+6 gestational weeks) were selected for this study.Fetalnuchal translucency (NT),facial angle (FA),ductus venosus (DV),fetal heart rate (FHR),tricuspid reverse (TR),nasal bone (NB) and fetal structures were scanned and measured.Risk calculation software (Astraia) was used to calculate the chromosomal abnormal risk (cut-off line:＞1/300) based on ultrasound records.The chorionic villi or amniotic fluid of high risk patients was collected with informed consent for karyotype analysis (prenatal diagnosis).All patients were followed up until six months after delivery.Chi-square test or Fisher exact test was used to compare the difference.Results One hundred and seven cases were high-risk of trisomy 21 among which 96 cases accepted invasive prenatal diagnosis.Sixteen chromosomal anomaly and six trisomy 21 cases were diagnosed out the 96 fetuses.Among 2789 cases,four were high-risk of trisomy 21 according to ultrasound screening.Six cases were diagnosed as trisomy 21.The false positive rate of ultrasound screening was 3.6％(101/2783).There were 196 cases whose NT ≥2.5 mm,in which 66 cases were high risk of chromosomal abnormality,and 16 fetal chromosomal abnormalities were diagnosed after chorionic villus sampling.The invasive procedure rate was 2.3％ (66/2789).Totally,186 pregnant women were older than 35 years,among which 32 cases were high risk.There was no significantly difference on the of rate fetal chromosomal abnormality between the groups of age≥ 35 pregnant women and the general population (P=0.055).But 29.9％ (32/107) high risk cases were detected in the group of age≥35.Five of thirteen fetal malformations cases were associated with abnormal karyotype.Conclusions Multiple ultrasound soft markers screening during early pregnancy could increase the diagnosis rate of chromosomal abnormality and decrease the false positive rate,false negative rate and invasive procedure rate.Early ultrasound screening might be effective in not only identifying chromosomal abnormality,but also diagnosing severe structure deformity of fetus.

Objective To investigate the effect of hypoxic preconditioning on hepatocytes early growth response factor 1 ( EGR-1 ) in a rat liver autotransplantation. Methods The rat portal vein perfusion model was established for donor liver autotransplantation. Rats were then divided into group A:hypoxic preconditioning was done before transplantation; group B: rats undergoing liver transplantation without preconditioning; group C: Normal control group of rats. Liver histopathological changes, the mRNA expression of HIF-1, TNF-1 and the WB results of EGR-1 were compared between groups. Results The expression of HIF-1 α RNA determined in group A was more obvious than in group B and group C. Six hours after surgery, the expression in group A was significantly higher than that in group B (t =9. 601, df= 10, 2-tailed Sig = 0. 000, P<0. 05 ) ; Egr-1 protein expression in group A and group B increased after surgery,with that in group A being significantly lower than that in group B. The RT-PCR expression of TNF-α RNA in group B compared with group A and group C was more obvious. Six hours after operation, the expression of TNF in group B was significantly higher than that in group A ( t = -12. 067, df = 10, 2-tailed Sig =0. 000, P<0. 05 ). The expression of Egr-1 was positively correlated with that of TNF. A liver cell pathology showed less severe injury in structure of hepatic lobule, mild swelling of liver cells, no significant changes in liver tissue. Conclusions Hypoxic preconditioning adaptation in rat liver transplantation generates modest increase in EGR-1, and reduces the production of TNF and other inflammatory factors.
