Objective To find out the difference or the regularity by the comparison study on the Auto-CPAP application to treating severe OSAHS patients in daytime nap and nocturnal sleep.It also supplies an evidence for reducing the expense in treating and testing severe OSAHS patients.Methods The patients who complained of snoring or dyspnea during sleeping and excessive daytime somnolence were selected as the subjects.They were monitored by PSG or Auto-CPAP ventilator system.Meanwhile their somnolent level were estimated by Epwoth.After that the patients with more than 20 AHI were selected as the advanced subjects.They were treated respectively in daytime nap and in the nocturnal sleep.And the daytime treating time lasted more than one hour and less than two hours and thirty minutes.Monitoring items included AHI,AI,HI,the longest duration of apnea or hyponea(LAHT),the lowest SaO\-2,the highest CPAP pressure(HP),median pressure(MP),90% pressure(90%P) and 95% pressure(95%P).Results The therapeutical effect is distinguished and is the same with the severe OSAHS in both daytime nap and nocturnal sleep.And also they need the same CPAP pressure level basically.Conclusion The CPAP pressure level titrated in daytime nap treatment period can be used in the nocturnal sleep therapy for severe OSAHS patients.

Objective To investigate the association between gene polymorphism of sortilinrelated receptor 1 (SORL1) and Alzheimer' s disease by detecting a series of single nucleotide polymorphisms (SNPs).Methods The Snapshot method was used to genotypc 6 SNPs (SNP10,19,23,24,25,27) in SORL1 and the distributions of allele and genotype of the 6 SNPs were compared between AD patients and healthy control individuals.Results There were significant differences in the genotype distributions of SNP19,23,24 and 25 between AD patients and control group (all P<0.01).Subjects with TT genotype in SNP19 had significantly lower risk for AD and was protective for AD (OR=0.089,95%CI:0.011-0.718,P<0.01).The AT genotype in SNP23 (OR=3.826,95%CI:1.388~10.544,P<0.01),CT genotype in SNP24(OR=5.935,95%CI:1.774-19.853,P<0.01)and CT genotype in SNP25(OR=5.754,95%CI:2.007-16.496,P<0.01)had higher risks for AD.Conclusions SORL1 gene variants of SNP19,23,24 and 25 might be the important risk factors for late-onset AD.

Course construction is the groundwork for vocational college to improve education quality. The first thing for the excellent course construction is to raise awareness. The fundamental starting point and destination are benefitial to students. It must start from the teachers themselves, and have entire optimization in the teaching content,teaching methods ,teaching materials, the means of teaching and so on.

OBJECTIVETo investigate the inhibitory effect of puerarin on invasive and metastatic abilities of tumor cells, and its possible mechanism through observing its impacts on the migratory, adhesive and invasive capacities of human oophoroma cells HO-8910 to the artificial recombined basement membrane.
METHODSExpression of estrogen receptor (ER) in HO-8910 cells was detected using PCR assay. Effects of puerarin on HO-8910 proliferation was detected with MTT assay; on its adhesion potential was tested with cell-matrigel adhesion assay, and on invasive and migratory capacities were measured with Transwell matrigel invasion assay and Transwell motility assay respectively.
RESULTSER was positively expressed in HO-8910 cells. After being treated with 20 micromol/L puerarin for 12 h, the adhesive test showed that OD value in the tested group was significantly lower than that in the control (P < 0.01), the inhibiting rate reached 50.63%; and the Transwell assay showed a significant lowering of penetrated cells (P < 0.01), the inhibition rate for invasion was 38.59% and that for motility migration 40.63%. The number of penetrated cells was lower in the group intervened with combination of Puerarin and estrogen than in the group intervened with estrogen alone, 33.40 +/- 3.30 vs 48.05 +/- 3. 56 for invasion and 35.35 +/- 3.03 vs 52.45 +/- 1.04 for motility (all P < 0.01).
CONCLUSIONPuerarin can inhibit the adhesion, invasion and migration of HO-8910 cells, plays an antagonist effect against the stimulation of estrogen on the malignant behavior of tumor cells.

Objective To explore the risk factors for lung cancer-related cerebral infarction . Methods The hospitalized active lung cancer patients on anti-cancer therapy with no traditional stroke risk factors, who experienced an acute cerebral infarct in the First Affiliated Hospital of Guangxi Medical University from January 2005 to December 2015, were consecutively collected as the LCRS ( lung cancer-related stroke) group.The active lung cancer patients without cerebral infarction hospitalized at the same peroid matched with the LCRS group for age and gender were collected as the LC ( lung cancer ) group. Clinical data from the two groups were analyzed .Results A total of 139 LCRS patients and 139 LC patients were enrolled in the study , with 110 male and 29 female in each group , and there were no significant difference for the mean age between the LCRS group (52.1 ±10.4 years old ) and the LC group (52.1 ± 10.1 years old).Two or more acute ischemic lesions of the brain were showed by MRI in most patients in the LCRS group (117 cases, 84.2%).Compared with the LC group, more patients in the LCRS group were found with adenocarcinoma , metastasis, elevated plasma D-dimer, CA125 and CA199 levels [ 88 cases (63.3%) vs 47 cases (33.8%);98 cases (70.5%) vs 56 cases (40.3%);(468.38 ±291.37) μg/L vs (277.59 ±191.22) μg/L;(221.42 ±146.34) U/ml vs (106.84 ±69.97) U/ml;(254.68 ±185.84) U/ml vs (97.15 ±63.64) U/ml;with all P<0.001].By logistic regression analysis of multiple factors , the elevated plasma D-dimer, CA125 and CA199 levels were showed to be independent risk factors for the cerebral infarction (OR=1.003, 95%CI 1.001 -1.004; OR=1.006, 95%CI 1.003 -1.010; OR=1.011, 95%CI 1.007-1.015).Conclusions The elevated plasma D-dimer, CA125 and CA199 levels are the risk factors for the lung cancer related cerebral infarction , which may lead to hypercoagulation and induce cerebral infarction eventually .

Objective To investigate the dynamic changes of the contents of brain water and Ca,Fe,Cu,Zn,Mg and microvascular damage in hippocampal tissue of radiation-injured rat brain.Methods The rats were randomly divided into control group,protective group (with intraperitoneal injection of 10% MgSO4,400 mg/kg body weight + a single dose of 20 Gy electron beam irradiation in whole brain) and irradiation alone group (with intraperitoneal injection of normal saline,400 mg/kg body weight + a single dose of 20 Gy electron beam irradiation to the entire brain) with 18 rats assigned to each group and 3 rats sampled at each time point.Radiation-induced brain injury (RBI) was modeled by irradiating the rat' s whole brain with 5 MeV electrons.A dry-wet weight method was used to detect brain water content (BWC),and the level of microvascular damage was detected with HE staining of brain tissue slices,and the contents of Ca,Fe,Cu,Zn,Mg in hippocampus were detected with inductively coupled plasma atomic emission spectroscopy at different time points after radiation.Results BWC in the irradiated rats at 7,14 and 30 d post-irradiation was higher than that of control group (t =3.21,-2.11,2.82,P <0.05),andBWC in the protective group was less than that in the irradiated group (t =2.84,4.33,1.90,P < 0.05).Microvascular thrombosis was induced in the radiated brain but this thrombosis was reduced by MgSO4.Thecontents of Ca and Fe in the brain tissue after 1,3,7 d of irradiation was higher than that of control group(t =11.41,6.81,14.03,17.17,6.89,9.12 and 5.43,5.66,3.60,P < 0.05),and the content of Cain the protective group at various time post-irradiation was less than that in the irradiated group (t =5.35,5.28,11.02,14.26,5.68,9.10,P <0.05).The content of Cu (1,7,14,60 d post-irradiation) andZn (1,7,14,30,60 d post-irradiation) of the irradiated group was less than that of the control group(t =4.24,3.76,4.76,3.86 and 5.25,4.78,26.53,6.67,11.37,P < 0.05),and the content of Cuin the protective group at different time points post-irradiation was less than that of the irradiated alonegroup (t =4.23,3.57,4.01,4.73,3.78,3.44,P <0.05),the content of Zn in the protective group(14 d post-irradiation) was higher than that of the irradiated group (t =6.21,P < 0.05).The content ofMg in the irradiated group (7 d post-irradiation) was less than that of the control group (t =5.85,P <0.05).Conclusions The contents of Ca,Fe,Cu and Zn were imbalanced in the radiation-injured ratbrain,and the supplement of MgSO4could recover the balance of Ca,Fe,Cu and Zn content and alleviateradiation-induced brain injury.
