Combined acupuncture-medication anesthesia refers to an anesthesia method by combining acupuncture and small dose of anesthetics, i.e. acupuncture plus local anesthesia, acupuncture plus epidural anesthesia, acupuncture plus general anesthesia, and so on, used in cardiac, chest, skull, throat, abdominal, and urinary operations. Clinical studies show that the combined acupuncture-medication anesthesia has integrated the advantage of acupuncture in regulating the function of internal organs and the advantage of drugs insedation, thus producing a better protective effect on important organs than dry drug anesthesia during and after operation. This article summarized the latest research progress of the combined acupuncture-medication anesthesia in protecting organs duringthe perioperative period of pneumonectomy, pointed out the research frontiers of the application of this anesthesia method in pneumonectomy, and was of valuable reference for the clinical study in the future.

AIM:To analyse the risk factors of age, sex, course, best corrected visual acuity(BCVA),diopter and fundus features of high myopes with progressive high myopia. METHODS: A total of 167 patients with high myopes were categorized into four groups: group 1,age of 29 years or younger; group 2,between the age of 30 to 49 years; group 3,between the age of 50 to 69 years and group 4,age of 70 years or older. The refractive errors of all patients were measured without cycloplegia with an autorefractometer. Data of the spherical equivalent(SE) of the refractive errors in diopters (D)and fundus examed by direct ophthalmoscope were used in statistical analyses.RESULTS: The number of female was statistically larger than that of male(P＜0.01),also the disease course was correlated to the age. The visual acuity of high myopes significantly decreased as they grew older including the higher incidence of lacquer cracker, submacular hemorrhage, Fuchs spots, chorioretinal atrophy . CONCLUSION: Female maybe a risk factor of high myopia, advanced age is an important factor of visual acuity decrease. High myopes ought to be treated early to delay the progress of myopia and development of macular degeneration.

Objective To study whether L-cysteine and lysolecithin (16:0) could be as a serum markers in the detection of OVC for overcoming the OVC defects of early detection .Methods Totally 142 cases of healthy check -up patients ( control group ) 100 cases from First Affiliated Hospital of Wenzhou Medical University in January 2012 to January 2014 were extracted patient specimens .These pa-tient specimens were used to detect by MALDI -TOF-MS mass spectrometer and obtain the peak m/z by the method of principal compo-nent analysis for screening expression difference between the two groups in the metabolites and the correlation between metabolites and pathological grade.Results The most difference substance between two groups were 184.05 and 496.30m/z which identified as LPC (16:0) and HCA;On HCA average level and detection rate , OVC group was significantly higher than control (P<0.01); On 184.05 and 496.30m/z peak area, control group was significantly higher than OVC group (P<0.01);HCA positively was correlated with patho-logic grade (P<0.05);184.05 and 496.30 m/z peak area were negative correlation with pathologic grade (P<0.05).Conclusion L-cysteine and lysolecithin (16:0) mechanism in the pathogenesis of OVC is unclear , but it can be used for the detection of serum OVC markers.

ObjectiveTo determine whether aadA2 gene can be translated from the ATG triplet,which there was no plausible ribosome binding site preceding it,and synthetized a functional protein in class 1 integron.MethodsSite-specific mutagenesis was used to construct aadA2 gene cassette with different start codons,together with their upstreamed promoters of variable regions were cloned into plasmid pACYC184 respective.The constructed plasmids were then transfored into Escherichia coli JM109,Western blot was used to detect the translation products of aadA2 gene with different start codons.Broth microdilution method was used to detect the minimal inhibitory concentrations to streptomycin in Escherichia coli JM109 containing aadA2 gene with different start codons.ResultsaadA2 gene can initiate translation from both ATG and GTG triplets in aminoacyl -3-adenylyltransferase protein synthesis,though there was no plausible ribosome binding site preceding the ATG triplet.Besides GTG and ATG triplets,there was other start codon downstream of the GTG triplet in aadA2 gene.The translated products that initiated from the start codons that described above were all functional AAD(3) proteins that can be detected by anti- aminoacyl -3-adenylyltransferase polyclonal antisera in Western blot and conferred different resistance levels to streptomycin in E.coli.ConclusionWhen inserted as the first gene cassette in class 1 integron,aadA2 gene can initiate translation from ATG triplet and synthetized a functional protein,though there was no plausible ribosome binding site preceding it.This structural characterization of class 1 integron can initiate translation of the open reading frame harbored in gene cassette that integrated into class 1 integron,though there was no plausible RBS preceding the start codon.This make class 1 integron be more convenience to express the genes that capture from environment.

ObjectiveTo prepare antiserum specific to aminoacy1-3″-adenylyltransferase [ AAD (3″) ],and to explore the application value of the prepared antiserum in detecting the expression levels of aadA2 gene that downstream of 8 different promoters (PcS,PcH2,PcH1,PcW,PcS-P2,PcH2-P2,PcH1P2 and PcW-P2 ) of variable regions in class 1 integron.MethodsaadA2 gene was amplified by polymerase chain reaction(PCR) and cloned into the expression plasmid pET19b.After inducing,the recombined aminoacy1-3″-adenylyltransferase[ AAD(3″)] with His-tag was expressed,purified and immunized rabbits to get anti- AAD(3″) specific serum.The prepared antiserum was used to detect the translation levels of aadA2 gene that downstream of different promoters of variable regions in class 1 integron by Western blotting (WB).Broth microdilution method was used to detect the minimal inhibitory concentrations (MIC) to streptomycin in Escherichia coli JM109 with aadA2 gene downstream of different promoters of variable regions.ResultsRecombined AAD (3″) expression plasmid pET19b-aadA2 was constructed successfully and was verified by sequence analysis.After transformed into E.coli BL21 ( DE3 ),a resoluble recombined AAD(3″) high expression strain was obtained.After fermentation,recombined AAD(3″) was purified and immunized rabbits.The anti- AAD(3″) specific serum was obtained with titer ＞ 1∶100 000.WB was used to detect the expression levels of AAD (3″),the translation product of aadA2 gene,that downstream of 8 different promoters of variable regions.The relative expression level of AAD (3″) that downstream of PcW was assumed to be 1,then the relative expression levels of AAD(3″),which all were detected 3 times independently,that downstream of PcS,PcH2,PcH1,PcS-P2,PcH2-P2,PcH1-P2 and PcW-P2 were 12.9±2.3,9.1±1.0,2.0±0.4,16.0±1.3,14.1 ±1.3,10.5±0.7 and 8.9 ±1.7 respective.Very different expression levels of AAD (3″) that downstream of different promoters of variable regions were obtained( F =32.421,P ＜ 0.01 ).The mean values of MIC,which all were detected 3 times independently,to streptomycin in E.coli JM109 with aadA2 gene downstream of PcS,PcH2,PcH1,PcW,PcS-P2,PcH2P2,PcH1-P2 and PcW-P2 were 256,256,64,128,32,128,4 and 64 mg/L respective.These results indicated the different expression levels of aadA2 gene that downstream of different promoters of variable regions can confer their host bacteria different resistance levels to streptomycin.Conclusions Resoluble recombined AAD(3″) is purified successfully and high titer anti- AAD(3″) specific antiserum is obtained from the immunized rabbits.This laid foundation for further investigation on the correlationship between the expressions of intI1 gene and the gene cassettes within variable regions.The expression levels of antibiotic gene cassettes that downstream of different promoters of variable regions are very different,so are the very different antibiotic resistance levels of the host bacteria.Therefore more attentions should be paid to the researches on the classification of promoters of variable regions when molecular epidemiology studies on the class 1 integrons in clinical isolates were conducted.

Background and purpose:KIT mutation plays an important role during the pathogenesis of melanoma. This study was designed to investigate the mutation status ofKIT in different subtypes of melanoma. Methods:A total number of 144 cases of melanoma were analyzed forKIT mutation (exon 9, 11, 13 and 17) by DNA sequencing using paraffin-embedded tissues.Results:The total incidence ofKIT mutation in melanoma was 9.0% (13/144).KIT mutations in acral melanoma, mucosal melanoma, melanoma on skin with chronic sun-induced damage (CSD) and melanoma on skin without chronic sun-induced damage (non-CSD) was 7.7% (4/52), 20% (7/35), 14.3% (1/7) and 2.8% (1/36), respectively. Among 13 cases withKIT mutation, 1 mutation lay in exon 9, 9 lay in exon 11 and 3 in exon 13. L576P in exon 11 was the most common type of mutation.Conclusion:The most prevalent type ofKIT mutation in patients lies in exon 11.KIT mutation could be the potential drug target in melanoma therapy.

Objective To develop a gut-brain interaction animal model of IBS which combines multiple factors including behavior, visceral sensation and motility. Methods Setting up a multifactor interactional animal model (chronic acute combining stress model, CACS) based on a chronic unpredictable mild stress model of depression (CUMS) while combined with wrap restraint stress (WRS) , changes of some indexes were recorded including motility (granules of defecating, time of defecating), visceral sensitivity ( spontaneous contraction of abdominal striated muscles ) and behavior/mind ( sucrose consumption, body weight). G protein subunits were measured by Western blot in both hippocampus and prefrontal cortex simultaneously. Results ( 1 ) Compared with the state before stress given, defecating granules increased, defecating time of glassie from rectum shorten, number of abdominal contraction increased, and sucrose consumption decreased in CACS, however, neither significant change was found on defecating behavior in CUMS nor on sucrose consumption in WRS; (2) Compared with the control group, some G protein submits expression decreased in both CACS and CUMS( P < 0. 05 ) , while no significant changes of any G protein subunits were found in WRS. Conclusion The CACS animal model was a new, brain-gut interaction model, which can mimic part of human symptoms of IBS very well.

Objective To observe the prokinetic effect of domperidone on colon and compare with that of mosapride and cisapride.Methods ① In viva experiment:forty rats were divided into control,domperidone,mosapride,and cisapride groups with 10 in each group.Stran gauges were planted both in proximal and distal colons and colonic motor activities were recoded in conscious rats.② In vitro experiment:the prokinetics effects of dopamine or dopamine combined with domperidone on the contraction of isolated rat colon strips were recorded by tone-transducers in the thermostatic muscle bath.Results In viva experiments:① in the interdigestive period of resting,activities of rhythimic phasic contraction were recoded in colon at conscious rats,and ② it had been showed that dornperidone significantly enhanced the contraction of colon in dose-dependent manner.Compared with control group,the mean contraction amplitude of proximal colon and distal colon increased by 84.61% ± 7.26% and 76.37 % ± 8.47% in domeridone group,respectively,which was higher than those in mosapride group (50.32%±8.16% and 45.13%±7.16%,respectively),but as same as those in cisapride group (92.55% ± 8.37% and 81.27% ± 9.95%,respectively).In vitro experiments:① perfusion of dopamin (40 mg/ml) could significantly decrease the contraction of isolated colon strip by 91.56% ± 10.24% in comparison with Krebs-Ringer solution,and ① domperidone could block the relaxant effect of dopamin on the isolated colon strip.Conclusions Domperidone can significantly enhance the colonic motor activities via antidopaminergic action.The effects of domperidone are similar as eisapride and greater than mosapride.
