Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(01):-
Objective To investigate the surface sterilization and modification of medical poly(tetrafluoroethylene)(PTFE) by remote argon plasma.Methods Carrier quantitative bactericidal test was used to examine the germicidal effect(GE) of the E.coli on the surface of medical PTFE film and surface structure,performances of sterilized PTFE were characterized by the water contact angle,mass loss and X-ray photoelectron spectroscopy(XPS).Results Both remote and conventional argon plasmas could sterilize effectively(GE≥3.769) in the conditions of plasma RF power 100 W,exposure time 120 s and argon flux 20 cm3/min.Remote argon plasma sterilization made the PTFE surface have higher hydrophilicity(?=58.5?) than the conventional argon plasma sterilization(?=70.5?) and did not cause remarkable degradation and damages in terms of the mass loss(mass loss was 11.8%).Remote argon plasma sterilization could enhance interaction reactions with argon radicals relative to those with electron and argon ions,thereby contributing more effectively to defluorination(F/C=2.24) from the PTFE than the conventional argon plasma sterilization(F/C=2.49) and more effectively to the formation of oxygen functionalities on the PTFE surface.Conclusion Remote argon plasma can inactivate E.coli effectively and at the same time bring better surface modification of PTFE.

Objective To discriminate the species and individual identification with mitochondrial DNA (mtD-NA) sequencing in forensic medicine practice. Methods The multiplex PCR of mtDNA loop - D high - variation region and cytochrome- b region were investigated. The PCR products were detected with silver- stain method,followed by analysis of the PCR products with fluorescence sequence technique. Results The presence of two bands (358bp,279bp ) indicated the samples were from human, while only one band of 358bp indicated nonhuman origin. The part of mitochondrial DNA loop - D high - variation region (15997 ~ 16236) from 131 unrelated individuals of Guangdong population were sequenced. In all of these samples there were 69 nucleotide variations and 67 haplo-types.There was 2.679 mutation sites on average per person. The polymorphism was 97.92% . Conclusion The methods described here are reliable and very useful in species and personal identification of degraded samples.

Objective The national essential medicine select system is the core of Chinese medicine policy.How to select drugs fundamental for eyes scientifically is an important ring in establishing the Chinese essential drug system.The present study attempted to compare the National Essential Medicines List and National Essential Insurance List of China with that of the WHO in order to provide reasonable evidence for the adjustment of a new National Essential Medicines List of China. MethodsThe WHO Essential Medicine List (15th edition,Version in 2007),National Essential Medicine List (Version in 2009,China),2009 National Essential Medicine List Chemical Medicine Name (Version in 2009) and National Essential Insurance List of China (Version in 2004) were reviewed.The similarity and difference in the category and number of drugs in the National Essential Medicines List and National Essential Insurance List between China and WHO were compared and analyzed.A descriptive method was adopted to analyze the sorts and numbers of eye drugs in the lists mentioned above.The analysis of drug price was based on the summary sheet from Zhejiang Province. ResultsLittle difference was found in the numbers of eye drugs between the National Essential Medicines List of China and WHO Essential Medicines List.Differences in the sorts of eye drugs were observed in the lists,especially between the National Essential Medicines List of China and WHO Essential Medicines List.Except for levofloxacin,all of the drugs in the National Essential Medicine List of China were included in the National Essential Insurance List of China.ConclusionThe selecting principle and renewing procedure of the National Essential Medicines List and National Essential Insurance List of China should be further improved in China based on the list from WHO.More attention should be paid to the standard,dosage form,affordability,maneuverability etc.during the selecting procedure of eye essential drugs.

Background The enhance of differentiation of orbital preadipocyte is a main factor for pathogenesis of thyroid associated ophthalmopathy(TAO).Experiment has proved that orbital preadipocyte can differentiate into mature adipocyte expressing resistin,and resistin is a adipocyte factor with biological activity.Objective The present study is to investigate the effects of recombinant human resistin on differentiation of orbital preadipocytes derived from TAO patients orbital tissues.Methods Orbital adipose tissue was obtained from 10 eyes with TAO during the orbital decompression surgery.Orbital adipose tissue of the normal group was obtained from 5 removed eyes during the surgery due to different reasons.Preadipocytes were isolated and cultured using expand culture method.The 2-5 generations of preadipocytes were identified by oil red O staining under the light microscope.0,10,25,50,100ng/mL of recombinant human resistin were added into medium in the first day after differentiation of cells.The expression of PPARγ mRNA in differentiated adipocytes were detected by reverse trancripaton PCR(RT PCR).Results The differentiation of preadipocyte presented the similar procedure and outcome between the TAO group and normal group.Differentiated adipocyte was stained into the jacinth by oil red O.The expression of PPARγ mRNA in differentiated cells was gradually declined with the increase of concentration of recombinant human resistin (F=241.341,P<0.01).A dose dependent inhibitory effect was detected in the expression of PPARγ mRNA.The weakest expression of PPARγ mRNA in differentiated cells was 100ng/mL resistin group.Conclusion The recombinant human resistin has an inhibitory effect on the differentiation of orbital preadipocytes by reducing the expression of adipose related genes.Resistin is probably a new research approach to treatment of TAO.
