This paper is to explore the feasibility of molecular sieve oxygen generator in the supply of oxygen in hospital. By introducing the different principles of oxygenation technology of pressure swing adsorption and oxygenation technology of heavy cooling, this article compared the merits of two ways in national regulations, safety, convenience, and economical efficiency. Oxygenation technology of pressure swing adsorption was more advanced, more automated and life-longer compared with cylinder oxygen supply and central oxygen supply. Molecular sieve oxygen generator is a new generation of oxygen generating equipment with a good application prospect, and can provide a better choice for hospital oxygen supply.

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

Objective To understand the status of human resources for AIDS control at city and county level in Hebei Province,and to improve the outfit of human resources.Methods General investigation and self-designed questionnaire were used by the trained investigators.Epi Data 3.0 was used to establish a database,and SPSS 13.0 was used to analyze the data.Results There were 1 347 missionaries at the city and county level,547 of whom were full-time staff.Significant differences existed in academic qualifications and titles between city and county level.A lack in technical staff in county level appeared.Conclusions The number of staff for HIV control in Hebei is not sufficient.Therefore human resources in these places should be strengthened and rationally allocated for AIDS control.

BACKGROUND: Using color Doppler ultrasonography, renal graft size, appearance, structure, and blood flow distribution can be observed. Through the use of blood flow display technique, blood flow perfusion of renal graft can be accurately observed to assist diagnosis and differential diagnosis of complications following renal transplantation. OBJECTIVE: To observe the hemodynamic characteristics during different periods of acute renal transplant rejection, summarize its specific manifestations through analyzing different reaction of two dimensional and color Doppler flow imaging (CDFI) during renal transplantation in order to get valuable index on acute rejection of renal transplantation.DESIGN, TIME AND SETTING: Comparative observation was performed at the Jinan University and First Hospital of Shenzhen University between January 2003 and January 2007.PARTICIPANTS: A total of 299 patients undergoing renal transplantation were divided into normal allograft group (n=236) and acute rejection group (n=63) according to renal allograft function.METHODS: The systolic peak flow rate, end-diastolic flow rate, mean flow rate, pulsatility index and resistance index of main renal artery and arcuate artery in patients of two groups were compared. MAIN OUTCOME MEASURES: Renal allograft arterial inner diameter and hemodynamics of two groups.RESULTS: Compared with normal allograft group, the blood flow perfusion was reduced at acute rejection, which could not reach cortex margin, blood velocity was decreased at the diastolic phase, pulsatility index and resistance index were increased (P < 0.05). CONCLUSION: Color Doppler ultrasound, as a convenient, economical and noninvasive technique, provides the reliable evidences for the renal artery pulsatility index and resistance index in clinic, and also is valuable for the acute rejection early diagnosis of renal allograft.

AIM: To observe the protein expression of vascular endothelial growth factor 1 (VEGF-1) in pulmonary arterial endothelial cells and VEGF-1 gene expression in lung tissue in rats with hypoxia-induced pulmonary hypertension and treated with heparin. METHODS: Twenty four male adult SD rats were randomly divided into three groups (8 rats each): a control group (group A), a group with hypoxia for 4 weeks (group B) and a group with hypoxia for 4 weeks and injected with heparin to abdominal cavity simultaneously (group C). Mean pulmonary arterial pressure (mPAP), right ventricle hypertrophy index (RVHI) and vessel morphometry were measured. The morphology of pulmonary artery was observed by HE staining. The expression of VEGF-1 protein in pulmonary arterial endothelial cells was determined by immunohistochemistry. The level of VEGF-1 mRNA in lung tissue was measured by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: mPAP, RVHI, pulmonary artery remodeling parameters, VEGF-1 protein expression in pulmonary arterial endothelial cells and VEGF-1 gene expression in lung tissue of the three groups from high to low were group B, group C and group A. It was statistically significant when compared between either two groups of the three (P<0.01). Linear correlation analysis showed that VEGF-1 protein was positively correlated with pulmonary artery remodeling parameters (r=0.974, P<0.01), and VEGF-1 mRNA was positively correlated with VEGF-1 protein (VEGF 120 mRNA, r=0.919, P<0.01; VEGF164 mRNA, r=0.896, P<0.01). CONCLUSION: Heparin may down-regulate the expression of VEGF-1 at the levels of transcription and translation, resulting in the inhibitory effect on rats with hypoxia-induced pulmonary hypertension.

Objective To discussed the relationship between multiple sclerosis(MS)and the genepolymorphism of HLA hoping that these results would be useful for further pathogeny studies,diagnoses,therapy and prognosis estimation of MS.Methods HLA-Ⅱ alleles in 32 patients with MS,36 nonimmunological neurological disease controls and 30 healthy controls,were identified by polymerase chain reaction-specific sequence primers(PCR-SSP)methods.Results The gene frequency of HLA-DR16 (7/32,1/36,0/30),DR11(7/32,3/36,1/30)and DQB1*0502(10/32,6/36,4/30)in patients with MS were higher than those in the 2 control groups.The gene frequency of DQB1*0601(8/32,12/36,17/30)in the patients with MS was lower than the controls.However,only the HLA-DR16 had significant difference (χ2=7.398,RR=17.94,P=0.011;χ2=5.52,RR=9.8,P=0.022).Conclusion HLA-DR16 alleles may be associated with the susceptibility to MS in Guizhou Province.
