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 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.

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 evaluate the biochemical and structural changes of apatinib in patients with progressive radioactive iodine-re-fractory differentiated thyroid cancer (RAIR-DTC). Methods:The participants (n=10) were followed up since March 2016. Treatment ef-fect was evaluated in using both biochemical [thyroglobulin (Tg) and thyroglobulin antibody (Tg-Ab)] and structural responses (target lesions, TL). Adverse events were also recorded over time. Results:The median follow-up was 7.9 months. The Tg level declined rapid-ly within 6 weeks after apatinib treatment, and the average decline ranged from 60%to 90%, indicating the immediate biochemical re-sponse of apatinib in progressive RAIR-DTC. The Tg level tended to stabilize thereafter. However, the Tg level rebounded by 4%–135%when withdrawal was performed for 3–14 days. The number of TLs decreased rapidly within 8 weeks, and the average decreased ranged from 40%to 60%, indicating the presence of rapid structural responses. Thereafter, the number of TLs continued to stabilize. TLs, in contrast to Tg, were not significantly affected by drug withdrawal. The rate of change in Tg (Tgvn) was positively correlated with the rate of change in TL (TLvn) [TLvn=0.17×Tgvn+0.50 (r=0.56, P<0.05)]. The apatinib dose was adjusted due to adverse events, which could be relieved after 3 to 14 days of withdrawal. Apatinib can effectively control the disease even at a reduced dose of 250 mg/d. Conclusion:Apatinib treatment showed a fast and sustainable biochemical and structural responses. Tg could be regarded as an objec-tive indicator. Tgvn is positively correlated with TLvn, and the response of Tg is more sensitive than that of TLs.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.
