Objective To compare the effect of two different time for intravenous dexmedeto-midine alleviates shivering during parturients cesarean undercombined spinal-epidural anaesthesia. Methods One hundred and twenty parturients delivery under combined spinal-epidural anaesthesiawere equally randomized into three groups.The parturients were intravenously injected with dexmedetomidine 0.4 μg/kg (15 min)at 15 min before the beginning of anesthesia (group A)or the time immediately after delivery of fetus (group B)respectively.Moreover,group C was the control group.Parturientsin group C were given equal volume of normal saline.Mean arterial pressure (MAP),heart rate(HR),pulse oxygen saturation (SpO 2 )and ear temperature were recorded respec-tively.Apgar scores of the fetus at 1 min and 5 min,the incidence and grade of shivering response, Ramsay sedative grade and adverse responses such as nausea,vomiting and traction reaction were re-corded as well.Results By 30 min after operation,2 parturients (5%)in group A,8 parturients (20%)in group B and 19 parturients (47.5%)in group C experienced shivering.Traction reaction was observed in 2 parturients (5%)in group A,in 3 parturients (7.5%)in group B and in 10 parturi-ents (25%)in group C respectively.Compared with group C,the incidence rate and degree of shive-ring were significantly lower in groups of A and B (P <0.05),as well as the traction reaction (P <0.05).The incidence rate and degree of shivering in group A were significantly lower than that in group B (P <0.05),but the incidence rates of traction reaction were not statistically different between the two groups.Conclusion Dexmedetomidine administered before combined spina-epidural anesthesia could prevented shivering response in parturients undergoing cesarean section better than being injected immediately after the birth offetus.

Objective To investigate the association of PPAR gamma Pro12Ala polymorphisms with conroy heart disease(CHD). Methods One hundred eighty impatients were recruited in the study. Venous blood samples were collected after 12 h of fasting from all patients. DNA was extracted and Pro2Ala polymorphism in the PPAR gamma 2 genes was genotyped through the PCR-RFLP. The frequency and distribution of Pro2Ala polymorphism in Chinese Han population with CHD were analyzed. Gensini Score based on coronarography were used to grade the coronary. Results There were a total of 135 CHD patients,of which 52 were affected with single coronary lesion,43 with multi-coronary lesion,and 45 were normal. The frequency of P12/P12, A12/P12 in the coronary lesion group were 92.6% (125/135) and 7.4% (10/135) which were similar to that of 93.3% (42/45) and 6.7% (3/45)(P =0. 548). In the single coronary lesion group, the frequencies of P12/P12 and A12/P12 were 94.0% (42/52)and 9.6% (5/52) ,and 90.0% (36/40) and 10.0% (4/40) in the bi-coronary lesion group,97.7% (42/43) and 2.3% (1/43) in the multi-coronary lesion group,with no significant difference among the three groups( P ＞0.05).There were no significant difference on the frequency of P12/P12 and A12/P12 between various subgroups defined according to Gensini score (P = 0. 246). Compared to the frequency in non-obese, the frequency of A12/P12 were significantly higher in the obese ( P = 0.028 ). In PPAR gamma 2 genes B the Exton BstuI enzyme restriction site genes, BMI,waist-hip ratio and total cholesterol in the carriers of P12A genotype were significantly higher than those in the P12P genotype carriers ( P ＜ 0. 05 ). Conclusions PPAR gamma Pro12Ala polymorphisms might not be associated with CHD in Chinese Han population. The frequency of A12/P12 in obese is significantly higher than that in non-obese. PPAR gamma Pro12Ala polymorphisms might be associated with adiposity and lipid metabolism.

Objective:To investigate the interfering effect of siRNA on the expression of VEGF in Hela cells.Methods:Three pairs of siRNA were designed according to the 1-5 extrons sequence of VEGF and synthesized by T7 RNA ploymerase transcription in vitro. To evaluate the inhibition activity of siRNA, Hela cells were transfected via siPORT Lipid. The interfering effect of siRNAs in hRPE cells was examined by semi-quantitative RT-PCR and immunofluorescence technique.Results:The results showed that the three pairs of siRNA could effectively inhibit gene expression of VEGF in Hela cells with the rates of 88.7%, 94.2% and 80.3%. But the 1-base mismatched siRNA and ssRNA(+) didn′t show significant interfering effect. Furthermore, it was found that siRNAs had a dose dependent inhibitory effect(5-10 pmol).Conclusion:The siRNAs synthesized by T7 RNA ploymerase in vitro could effectively and specifically interfere the expression of VEGF in Hela cells, providing a novel approach for gene therapy of tumor.

Objective:To explore expression levels of Tim and TLR gene family in children with different types of mycoplasma pneumonia and their clinical significance.Methods: 56 patients with mycoplasma pneumonia were randomly selected in Ji′nan Maternity and Child Care Hospital from March ,2013 to March,2014.All the patients were divided into bronchopneumonia group ( n=40) and segmental pneumonia group (n=16) according to their X-ray manifestations.Bronchopneumonia group was characterized as dot,nodular increased density shadow with or without reticular ,stripe-like interstitial lesion.Segmental pneumonia was described as segmental or lobar consolidation of lung in X-ray.Meanwhile,30 healthy children were involved in control group with matched age and gender.Peripheral venous blood of all the children in every group was collected and total RNA was extracted .The mRNA of Toll-recepter 2,4 and Tim1,3 was quantified by quantitative real-time PCR (qRT-PCR),and compared between different groups.Results:The expression of mRNA of TLR-2,4 and Tim1 significantly increases in both bronchopneumonia group and segmental pneumonia group compared to healthy control.Meanwhile,the mRNA of TLR-2,4 and Tim-1,3 was significantly elevated among segmental pneumonia group compared to healthy control.In addition,the gene expression of Tim1,3 was higher in segmental pneumonia group than broncho-pneumonia group.Conclusion:The TLR-2,4 and Tim1 gene are over expressed in both types of mycoplasma pneumonia and Tim-1,3 are highly expressed in children with severe infection in lung.The expression alteration of TLR-2,4 and Tim1,3 gene is involved in different types of mycoplasma pneumonia.
