Journal of Peking University(Health Sciences) 2004;0(03):-
Objective:To describe the status of self-rated health(SRH)among the elderly and find out the relationship between SRH and other health measures such as two weeks prevalence and chronic disease prevalence.Methods:The data used was generated from cross-sectional household health survey conducted in the year of 2009 in Shunyi district,Beijing.SPSS software was used to conduct univariate and multivariate liner regression analysis with self-rated health.Results:The average score of self-rated health among the elderly is 72.49.Univariate analyses suggest that are age,sex,marital status,income level,education,employment,medical insurance type,self-perceived anxious or depression,disease state are all associated with poor SRH score.Multiple liner regression model shows that age,job,medical insurance,self-perceived anxious or depression,suffer from two-week illness and chronic disease had effects on SRH of the elderly.Conclusion:Physical and psychological unhealthy are independent risk factors of SRH among the elderly,disease status is the most influential predictor on SRH score.Thus,a single measurement of SRH question can be used in health status assessment of the elderly.

objective: To evaluate the embolization effect of 5 Fu gelatin microsphere(FGM) in oral and maxillofacial region.Methods: FGM was prepared with drug load of 12% and encapsulation of 85%. After irridiated with 60 Co, FGM was suspended into 76% of meglumine diatrizoate, and then perfused into external maxillary artery and lingual artery in 8 dogs under X ray observation. 4 dogs were used in each artery embolization. Blood flow velocity and volume in the arteries were tested at different time after embolization; all the data were analyzed statistically. The sections of embolized tissue at different time were examined microscopically. Results: Before and 1 h, 48 h and l month after ombolization the blood flow volume(ml/min) in external caroted artery was 43?5.0, 31.0?4.5, 26.5?4.0 and 35.0?30; that in external maxillary artery 5.0?1.5, 0.5?1.0, 2.5?1.0 and 3.0?1.5; in ligual artery 3.5?1.0, 0.5?0.5, 0 and 0; in internal maxillary artery 17.0?4.0, 19.5?4.0, 19.0?4.5 and 21.0?3.5, respectively. Stuff of the cavity of the corresponding arteries by FGM were found with histological examination. Conclusion: FGM can embolize artery completely.

Objective To investigate the frequencies of human leukocyte antigen ( HLA)-DRB1 alleles of Chinese Marrow Donor Program (CMDP) donors in seven markets of Jiangsu Han population. Methods 2787 donors from CMDP Jiangsu Branch were typed in HLA-DRB1 locus using polymerase chain reaction-sequence-based typing (PCR-SBT) method or polymerase chain reaction-reverse sequence specific oligonucleotide probes (PCR-rSSOP) method. Frequencies of HLA-DRB1 were separately calculated in seven markets and a comparison was made among them. Results A total of 38,33,26,36,37,31,26 alleles in DRB1 locus were separately found in Huai-an, Xuzhou, Taizhou, Suqian, Nanjing, Changzhou, Yangzhou population. The most frequent HLA-DRB1 alleles in Huai-an, Xuzhou, Suqian respectively were DRB1 * 07:01, 09:01, 15:01,12:02; In Nanjing and were DRB1 * 09:01,07:01, 15:01, 12:02; In Yangzhou were DRB1 * 09:01,07:01,15:01,08:03; In Taizhou were DRB1 *09:01, 07:01, 04:05, 15:01; In Changzhou were DRB1 *09:01,07:01, 12:02, 08:03. Conclusion The above results reflected the distribution of HLA-DRB1 alleles in seven markets of Jiangsu Han population, which held abundant polymorphism, and a certain uniqueness in every market. The HLA-DRB1 allele distribution of Nanjing, Yangzhou were the closest groups to northern China, Huaian, Xuzhou, Suqian, Changzhou, Taizhou were close to northern China except DRB1 * 09:01,07:01 in different frequencies. These findings could guide the selection of future donor in CMDP Jiangsu Branch. It also could serve as foundation for HLA related disease research, studies of population genetics and anthropology in Chinese Han population.

Objective To study the association of single nucleotide polymorphism (SNP) of the protein tyrosine phosphatase-1B (PTP-1B) gene with type 2 diabetes mellitus and obesity in Chinese. Methods SNPs in the PTP-1B gene were detected by direct sequencing to PCR products, and the detected SNPs were genotyped in case-spouse samples with the technique of fluorescence real-time PCR. Results Totally 6 SNPs were found in PTP-1B gene. Three SNPs (I5/37 C→A,I6/82 A→G, I7/301 C→T) were in the intron regions and the other 3 (E8/45 C→T, E9/35 G→A, E10/372 G→A)in the exon regions. Among them, E9/35 G→A was a newly found mutation site. The A allele frequency of I5/37 C→A, T allele frequency of I7/301 C→T and G allele frequency of I6/82 A→G in type 2 diabetes were significantly higher than those in the normal spouse group (P

Objective:To explore the interventional effect of β-sitosterol on ovalbumin(OVA)-induced allergic asthma rats and its potential mechanism.Methods:SD male rats were randomly divided into normal group(CON),model group(M),positive drug dexamethasone group(DEX,0.075 mg/kg)and β-sitosterol group(Sit,50 mg/kg).A rat model of allergic asthma was estab-lished by intraperitoneal injection of OVA with aluminum hydrogen solution,and nebulized inhalation of OVA to stimulate.Rats were given intragastric administration 30 min before aerosol challenge,and after continuous administration for 7 days,the indicators of cough and asthma and tracheal phenol red excretion were detected.HE staining was used to observe pathological changes of lung tis-sue.Flow cytometry was used to detect reactive oxygen species(ROS)generation,apoptosis level and ratios of Th17 and Treg cells in peripheral blood.Biochemical method was used to detect contents of MDA,and activities of T-SOD and GSH-Px in rat lung tissues.ELISA was used to detect levels of Th17 and Treg-related cytokines(TNF-α,IL-4,IL-6,IL-17A,and IL-35).Results:Compared with model group,β-sitosterol significantly prolonged the incubation period of cough and gasp in rats with allergic asthma,reduced the frequency of cough and gasping,and promoted the excretion of phenol red in trachea;significantly reduced inflammatory infiltration in lung tissue of asthmatic rats;observably reduced MDA content in lung tissue,ROS of primary lung cell and apoptosis levels of asthmatic rats,increased the activities of T-SOD and GSH-Px;markedly reduced proportion of Th17 cells and levels of pro-inflammatory cyto-kines TNF-α,IL-4,IL-6 and IL-17A,increased proportion of Treg cells and levels of anti-inflammatory cytokine IL-35.Conclusion:β-sitosterol can ameliorate airway inflammation and oxidative damage in OVA-induced allergic asthmatic rats,and its mecha-nism may be related to the regulation of β-sitosterol on Th17/Treg immune imbalance and oxidative stress response.
