Objective To explore the therapeutic effects of dexmedetomidine for cesarean shivering after spinal-epidural anesthesia and observe the maternal adverse reaction.Methods 94 patients with cesarean shivering after spinal-epidural anesthesia in our hospital were divided into the two groups according to random number table.The study group(47 cases) was given 0.3μ g/kg of dexmedetomidine by intravenous injection after the baby delivered,while the control group (47 cases) was given 1mg/kg of tramal after the baby delivered.The maternal shivering changes were observed,the Ramsay sedation scores before (T0),5min after treatment (T1),10min after treatment (T2) were recorded,and the maternal adverse reaction was compared between the two groups.Results After the treatment,the shivering effective rate of the study group was 93.6％,and which of the control group was 95.8％,the two groups showed no significant difference (P ＞ 0.05) ; Ramsay sedation score of T1,T2 in the study group was (3.21 ± 0.73) and (3.28 ± 0.65),which were significantly higher than T0 (1.53 ± 0.51),and significantly higher than (1.84 ± 0.71) and (1.92 ± 0.63) in the control group (t =5..43,9.81,all P ＜ 0.05).The incidence rate of adverse reaction of the study group was 6.4％,which was significantly lower than 57.4％ of the control group(x2 =19.20,P ＜ 0.05).Conclusion The therapeutic effects of dexmedetomidine for cesarean shivering after spinal-epidural anesthesia is good and it has good sedative effect,and it is safe,which is worth to be promoted in clinical.

The experiment of recirculating blood perfusion device showed that trimetazidine (TMZ ) 30 mol/L could significantly inhibit the arrhythmias induced by ischemia and reperfusion, decrease the content of malondialdehyde and improve superoxide dismutase activity of red blood cell in isolated rabbit hearts. In the experiment with coronary artery occlusion of rats, TMZ 4mg/kg administered intravenously could also inhibit arrhythmias induced by ischemia and reperfusion. The mechanism may be related to the depression of lipid peroxidation reaction.

0.05) in VAS and ramsay scale, but side effects were significantly different in group B compared with those in group S. Conclusion: The analgesia efficacy of S is same as B in maxillofacial postoperation, but side effects are more significantly in group B, and group S is more safe and handy.

Objective To identify routine forensic samples by genotyping method for HLA - A locus. Method A two - step PCR - SSP method was established. The first step is amplification with a pair of primers specific for all HLA - A alleles, the second step is amplification with primers specific for HLA - A30, A31, A33 respectively, using the first step amplification product as template. Secondly amplified PCR products were genotyped by electro-phoresis. Results 100 blood stains with a serological typing result of HLA - A30, A31 and A33 were tested with this method. The discrepancy rate between serological and genetic typing was 29%. Seminal stains, salivary stains reserved for 2 years and blood stains reserved for 18 years in room temperature gave satisfactory results. Conclusions It is better to replace serological typing by genetic typing. A two - step PCR - SSP genotyping method can be applied to forensic samples.

Objective To explore the relationship of neutrophil and interleukin-8(IL-8)with exercise-induced asthma(EIA).Methods From May 15,2001 to Dec 19.2005 the levels of peripheral neutrophil superoxide anion and IL-8 in the blood and the induced sputum from patients with EIA,non EIA and normal control subjects were measured respectively before and after exercises,meanwhile a comparison was made among them.Results Before exercise:the level of neutrophil superoxide anion was slightly higher in EIA group and non EIA group than that in control group;however,the differences were insignificant;the IL-8 and MDA levels in blood and induced sputum were higher in EIA group and non EIA group than those in control group,but there was no significant difference between EIA group and non EIA group;however,they were significantly different between EIA group and control group,non EIA group and control group respectively( P 0.05).Conclusion Oxyradical produced by neutrophil and IL-8 has significant effect on the production of EIA.

Objective To find out the distribution of the subunit of Gs proteins (GNAS1) T393C polymorphism genetic in congestive heart failure patients and to investigate the effects of genetic polymorphisms on the therapeutic efficacy of carvedlol. Methods Genotype of 65 patients with congestive heart failure (heart function was ranked Ⅱ~Ⅳ level by NYHA) underwent PCR-RFLP for GNAS1 polymorphism genetic analysis, and then were treated with carvedlol. The initial dosage of carvedlol was 12.5 mg once daily in patients , and increased by 6.25 mg every 1 ~ 2 weeks for 12 months to a maximum dosage within 50 mg/d. Degree of LVEF changes and heart function improvement was adopted as measuring index , effect of Gs proteins α subunit T393C genetic polymorphism on carvedlol response in congestive heart failure patients was analyzed. Results After carvedlol treatment for 12 months , NYHA class distribution and LVEF in congestive heart failure patients improved significantly (P < 0.05). After carvedlol treatment for 6 months and 12 months mutation symptoms patients′ heart function improved significantly (P < 0.05) and LVEF increased significantly (P < 0.01). Conclusions GNAS1 T393C genetic polymorphism can influence the therapeutic efficacy of carvedlol in chronic congestive heart failure patients. 393 homozygous mutant and mutated symptoms patients′ heart improved more obviously and their LVEF improved more significantly.

Objective To investigate the effect of psychological intervention on patients with non-small cell lung cancer treated with cisplatin or gemcitabine or Changchun vinorelbine. Methods 64 cases of patients with non-small cell lung cancer after surgery, nursing for patients in the group given basic treatment, routine care control group, the observation group based on routine nursing and psychological nursing effects were compared between the two groups. Results No significant difference of anxiety and depression in the patients of the two groups before nursing, after grouping nursing, the observation group improved significantly; compared two groups of patients with quality of life score, visible two group before the intervention had no significant difference after intervention group was clearly observed after the patients in the observation group were higher than that of the control group, comparison between groups were indicates that the difference is obvious (P<0.05). Conclusion Chemotherapy in non-small cell lung cancer after surgery for patients with psychological intervention, compared to conventional nursing, can improve the psychological status of patients with better, improve the quality of life of patients, so it is worthy of reference in clinical use.

Objective: To evaluate the effect of propofol and penthiobarbital on the postoperation conscious level in patients after general anesthesia. Methods: 116 patients with maxillofacial operation were randomly divided into two groups. Propofol was used in 60 cases and penthiobarbital in 56 for sedation. Wake score,anoxia and local stimulation in vein were examed.Results: In the 60 cases treated with propofol anoxia and local vein stimulation were observed in 2 and 7 cases, the restlessness score and the consciousness scores were 1.28?0.76 and 1.9?0.7; in the 56 cases treated with penthiobarital those were in 13 and 35 (P

AIM: To preliminarily study the molecular mechanism for the cardiac injury in rat by adriamycin and the mechanism for the acute repair in the body. METHODS: The male Sprague Dawley rats were randomly divided into four groups (n=10 in each): The first group was kept without treament and served as the control ;the second, the third and the fourth received ADR in different doses (10, 20, 40 mg?kg -1 , respectively) by injection of adriamycin. The content of malondialdehyde (MDA)in the serum was estimated with thiobarbituric acid. Cu Zn SOD was measured by its reaction with xanthine oxidase. GSH was measured by its reaction with 5, 5 nitrobenzoic acid. Using semi quantitative reverse transcription polymerase chain reaction (RT PCR),we analyzed the expression of the associated gene. RESULTS: MDA contents in the medium and high ADR dose groups were higher than that in the control group (P

OBJECTIVE To observe a time course of keratinocyte growth factor(KGF) and surfactant protein A(SPA) changes in rats with Pseudomonas aeruginosa pneumonia and to find out the significances of them.METHODS Specific pathogen-free male Sprague-Dawley rats were used to study.Standard P.aeruginosa strain ATCC 27853 was instilled into airway by the tracheal route to induce model of pneumonia.Samples of lung tissue and BALF were harvested before infection,and 6 h,9 h and 72 h after infection.Six rats per each point were sacrificed for harvesting samples.Expression of KGF protein in lungs was detected by Western blotting.Western-dot-blot was used to detect SPA expressions in BALF.RESULTS After infected with P.aeruginosa,KGF protein in lungs was markedly increased,reached the peak at 72 h postinfection.KGF protein level at 72 h postinfection was markedly higher than that of before infection(P
