ObjectiveTo study the anesthesia effect,safety and reliability of etomidate combined with remifentanil in elderly patients. Methods40 patients scheduled for abdominal operation were divided into two groups with 20 cases each: etomidate group(group A)and propofol group(group B).Anesthesia induction: midazolam 0.04mg/kg,remifentanil 1.5 μg/kg(time>60s),atracurium 0.6mg/kg,group A to etomidate 0.2mg/kg(30 ~ 60s),(T1),1 min before trachea intubation(T2),1 min after trachea intubation(T3),5 min after cutting skin(T4),5 min after exploration(T5),5min after cutting ill focus(T6),3min after tracheal extubation(T7),30min after operation(T8).At the same time,observed analepsia condition. ResultsIn group B,SBP and DBP were lower than those in group A at T2,T3,T4 and T5(all P<0.05).In group B,DBP was lower than those in group A at T6 and HR was lower than those in group A at T3 and T7(all P<0.05).In group B,SBP and DBP were lower than before anesthesia at T2,T3,T4 and T5(all P<0.05).In group B,DBP was lower than before anesthesia at T6 and HR was lower than before anesthesia at T2(all P<0.05).In group A,HR was faster than before anesthesia at T7(P<0.05).The time of openingeyes,remove-tracheal tube in B group was less than those in A group(all P<0.05).Both groups without memory about operation,anesthesia was content. ConclusionEtomidate combined with remifentanil anesthesia was milder than propofol group to elderly patients ardiovascular effects.It was better than propofol group for elderly patients.

Objective To investigate the relationship between single nucleotide polymorphisms of surfactant protein C(SP-C)gene and respiratory distress syndrome(RDS)in the Han nationality newborns in Inner Mongolia and whether there is a mutation occurs on SP-C gene exon 4 and 5.Methods One hundred newborns with RDS(case group)and 100 newborns without RDS(control group)were selected.PCR gene analysis was used to establish the genotype and allele frequencies of exon 4 (T138N)and 5 (S186N)on SP-C.Results In the Han nationality newborns of Inner Mongolia region,there was no mutation on SP-C gene exon 4 and 5.Exon 4(T138N)on SP-C could be checked out three genotypes:namely AA,AC and CC.The genetic polymorphisms of exon 4 on SP-C were not statistically different between the case group and the control group(χ2 ﹦0.744,P ﹦0.689).Besides,exon 5(S186N)on SP-C could also be checked out three genotypes:namely AA,AG and GG.The genetic polymorphisms of exon 5 on SP-C were also not statistically different between the case group and the control group(χ2 ﹦0.770,P ﹦0.681 ).Conclusion There is no mutation on SP-C gene exon 4 and 5.The genetic polymorphism of exon 4 and 5 on SP-C displays no signifi-cant correlation with RDS of the Han nationality newborns in Inner Mongolia.

This study aimed at exploring the application of microtox technology to the evaluation of comprehensive toxicity of Sheng Mai injections.Characteristic parameters of vibrio fischeri (CS234) were measured by methodology inspection under different conditions to optimize the reaction condition with reliable technology.It was the first experiment to accomplish the comprehensive toxicity of Sheng Mai injections from various manufacturers using vibrio fischeri under the target condition.It was found that parameters of the optimum condition contained 0.9 mL recovery liquid volume in each freeze-dried vial and 50 μ L bacteria suspension of each sample,being included in 2 mL solution in aggregate under 10 mins' detection time after adding bacteria suspension with the favorable pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million within 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15%.Under this optimum detection condition,it was found that the EC50 values were 22.10%,34.10% and 46.04%,respectively,presenting significant statistical differences (P<0.05).These results demonstrated that the growth of biological detection standards of Sheng Mai injection was highlighted a long way to go.Besides,the microtox-based fast test for the evaluation of the comprehensive toxicity of Sheng Mai injection showed a prospective application to controlling the quality of different products from manufacturers.

In this research,we chiefly explored a new fast test method--microtox technology to evaluate the comprehensive toxicity of Shen Mai injection.We investigated characteristic parameters of vibrio fischeri (CS234) under different conditions in the pursuit of the optimum test parameters of the reliable method;and then locked the best parameters for Shen Mai injection assay with the products from different manufacturers by microtox fast test.As a result,the optimum reaction condition included 0.9 mL recovery liquid in each freeze-dried vial and 50 μL bacteria suspension of each sample within 2 mL solution in aggregate with 10-mins detection after adding bacteria suspension which pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million in 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15%.Under this optimum detection condition,it was found that the EC50 values were 35.60%,92.34% and 146.57%,differing among the samples from three representative drug manufacturers,respectively (P < 0.01).In conclusion,the concentration-effect relationship of Shen Mai injection existed in the toxicity assessment of vibrio fischeri with various ECs0 values from the three manufacturers.These results suggested that biological detection standards of Shen Mai injection presented great growth potential.Microtox-based fast test in the evaluation of comprehensive toxicity of ShenMai injection showed favorable application prospects over controlling the quality of different sources of products.

Objective To study the relationship between gene mutation and clinical phenotype in patients with tuberous sclerosis complex (TSC).Methods The clinical data of 76 patients with TSC diagnosed in Guangdong 999 Brain Hospital were collected between May 2007 and May 2014 and then TSC gene mutation analysis was performed.Genotype-phenotype analyses for all the patients were also carried out.Results Fifty of the 76 (66%) patients were male,and 26 (34%) were female,in which 19 (31%) patients presented with cyst-like cortical tuber,69 (92%) with skin lesions,16 (30%) with renal lesions,50 (69%) with mental retardation and 39 still suffered seizures after a year.In this study,22 (29%) cases showed TSC1 gene mutation,31 (59%) presented TSC2 gene mutation,and 15 (20%)cases had no mutation identified.The mutation ratio of TSC1 ∶ TSC2 was approximately 3 ∶ 5,while the mutation ratio of TSC1 ∶ TSC2 was 1 ∶ 1 for familial TSC patients,and 1 ∶ 2 for sporadic TSC patients.Comparing to those with TSC1 gene mutation and no mutation identified,patients with TSC2 gene mutation exhibited statistical meaning on the aspects of the onset age of seizure (Z =1.688,P =0.007),seizure onset before l-year-old (x2 =10.584,P =0.001),epilepsy duration (x2 =4.996,P =0.025),spasms onset (x2 =10.111,P =0.001),cyst-like cortical tuber (x2 =9.182,P =0.002),skin lesions (x2 =9.016,P =0.003),as well as renal lesions (x2 =6.079,P =0.014).No apparent relation was found between genotype and intelligence outcome.Conclusions The patients with TSC2 gene mutations presented severer symptoms in seizure onset than those with TSC1 gene mutation and no mutation identified.The patients with TSC2 gene mutation were characterized by early onset of seizure,especially before 1-year-old,others like spasms onset,cyst-like cortical tuber,skin lesions,as well as renal lesions being more vulnerable.Therefore,more active treatment should be given to the patients with TSC2 gene mutation.

Relatively uniform-sized nanoparticles made of poly (lactic-co-glycolic acid) (PLGA) were prepared by premix membrane emulsification method. After the drug loading property was completed, the dynamic tissue distribution of nanoparticles was recorded. With the average particle size and span as indexes, membrane pore size, number of passing membrane times, membrane pressure, volume ratio of oil-water phase and the concentration of poly(vinyl alcohol) (PVA) in external water phase were investigated by single factor test, the optimum preparation technology of blank PLGA nanlparticles was as following: pore size of SPG membrane was 1 μm, membrane pressure was 1. 15 MPa, the number of passing membrane time was 3, the mass fraction of PVA of 2%, volume ratio of oil-water phase of 1 : 5. Prepared nanoparticles were round with smooth surface, the mean diameter was 332.6 nm, span was 0.010, the confocal laser scanning microscope (CLSM) concluded that fluorescent substance is uniform composizion in PLGA nanoparticle, and the in vivo imaging technology in mice include that the nanoparticles show good liver and spleen targeting property.
