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.

Objective:To investigate the in vitro effect of capsaicin on four major rat cytochrome P450 ( CYP) enzymes using a cocktail probe drug method. Methods:The in vitro incubation was divided into capsaicin group and the control group. Rat liver micro-somes, probe drugs, capsaicin at various concentration ( buffer solution in the control group) and cofactors were cultured altogether for 20 min. After the culture, the concentration of metabolites was determined by HPLC to assess the activities of enzymes. IC50 value of capsaicin on every isoform was calculated using Graphpad prism 5. 0. Capsaicin and hepatic microsomess were pre-incubated respec-tively for 0, 5, 10, 15, 20 and 30 min, and then the relative activity of the four isoforms at different time was calculated. Results:The activity of the rat liver microsomes enzyme CYP450 isoforms (CYP1A2, CYP2C11, CYP2E1 and CYP3A2) was all inhibited by capsaicin in vitro with IC50 value of 36. 21, 17. 19, 51. 64 and 18. 86 μmol·L-1 , respectively. Pre-incubation could not increase cap-saicin inhibitory activity against the four CYP enzymes. Conclusion:Capsaicin shows inhibition on CYP1A2, CYP2C11, CYP2E1 and CYP3A2 in rat liver microsomes in vitro without pre-incubation time-dependent property.

To investigate the rat intestinal absorption of stearic acid-octaarginine (SA-R8) modified solid lipid nanoparticles containing paclitaxel (SA-R8-PTX-SLN), compared with the commercially available preparation of PTX (Taxol) and PTX-loaded solid lipid nanoparticles (PTX-SLN), the in situ intestinal absorption of SA-R8-PTX-SLN was investigated by means of single-pass rat intestinal perfusion technique. The absorptions of the preparations were investigated at different intestinal segments, different drug concentrations and in the presence of P-glycoprotein inhibitor (verapamil). The results showed that PTX could be absorbed at each intestinal segment and the three preparations all showed maximum absorptions at the duodenum. The cumulative absorptions of three preparations at each intestinal segment appeared SA-R8-PTX-SLN > PTX-SLN > Taxol (P < 0.05). SA-R8-PTX-SLN showed a liner absorption manner at the duodenum in the examined drug concentration range. The cumulative absorptions of Taxol and PTX-SLN were significantly promoted after the addition of P-glycoprotein inhibitor (verapamil) into the preparation (P < 0.05), but absorption of SA-R8-PTX-SLN existed no significantly difference compared with the preparation without verapamil (P > 0.05). SA-R8 and SLN might both effectively improve the oral absorption of PTX in the intestinal tract.
