Objective:To investigate the relationship of family history , psychosocial factors of PD (Parkinson's Disease) in a rural population in north China. Methods: A case control study was conducted in rural population in China. Cases (n=77) have been diagnosed by a two-phase screening by neurologists and interviewers in May, 2000. Controls (n=154), randomly selected from the same cohort, who were matched with patients (control/cases ra-tio=2) for sex, age (?5 years). Information of participants' characteristics came from the interview in 2001. Data was analyzed by using conditional logistic regression by SAS 6.12. Results: Family history (OR=13.54) .negative life events (OR=3.02), interpersonal communication (OR=2.10) were associated with a significantly elevated risk for the onset of PD. Conclusion: These results indicate that family history, psychosocial factors were risk factors of PD.

Objective:To study the transdermal absorption in vitro of sinapine thiocyanate,tetrahydropalmatine and asarinin in Xiaochuan ointment so as to offer reference for its clinical application.Methods:A Franz diffusion cells method with isolated rat skins was carried out to study the percutaneous rate of sinapine thiocyanate,tetrahydropalmatine and asarinin determined by LC-MS/MS.Results:With the increase of administration dosage,the cumulative penetration of sinapine thiocyanate,tetrahydropalmatine and asarinin showed few changes.The results showed that the transdermal behavior of sinapine thiocyanate fit to a Higuchi equation,and that of tetrahydropalmatine and asarinin fit zero-order process.The penetration rate of tetrahydropalmatine and asarinin respectively was 0.362×10-1 and 0.330×10-2 μg·cm-2·h-1.Conclusion:Xiaochuan ointment exhibits transdermal penetration and absorption properties,which provides evidence for its transdermal administration.

The array CGH technique (Array Comparative Genome Hybridization) has been developed to detect chromosomal copy number changes on a genome-wide and/or high-resolution scale. It is mainly used in human genetics and oncology. Generally PCR amplified bacterial artificial chromosomes (BACs) or cDNAs have been spotted on the arrays as probes. Recently, however, oligonucleotide arrays designed with more flexibility and provide much higher resolution with high sensitivity, have been successfully explored in stead of BAC array CGH and can save considerable time and efforts. There will be a gradual transition from BAC array CGH to oligonucleotide array CGH in the coming years. The combination of oaCGH and other high-through put analysis can lead to discoveries of a host of novel oncogenes, tumor suppressors as well as tumor drug resistance genes. Some major platforms of oaCGH concerning their spatial resolution, optimal probe length, sensitivity, specificity and application in recent years were compared.
7.The relationship between serum uric acid and percutaneous oxygen partial pressure in patients with type 2 diabetes
Chinese Journal of Diabetes 2015;(4):345-348
Objective To explorethe relationship between serum uric acid (SUA ) and transcutaneousoxygenpressure(TcPO2)inpatientswithT2DM.Methods 622hospitalizedpatients with T2DM were recruited and divided into high SUA (HUA) group and normal SUA (T2DM) group.The differences in TcPO2 (initial value ,stable value ,initial value‐stable value ,leg‐raising initial value and leg‐raising maximum value)were compared between two groups.The correlations between SUA and TcPO2 were evaluated. Results The levels of TcPO2 were lower in HUA group than in T2DM group [initial value:left (34.05 ± 13.17) vs (39.26 ± 15.82) ,right (34.71 ± 14.90) vs (40.15 ± 16.23);stable value:left (38.93 ± 12.23) vs(45.19 ± 13.40) ,right (39.98 ± 12.34) vs (45.90 ± 16.77) ,P<0.05]. Pearson correlation analysis showed that the SUA levels negatively related with the stable TcPO2 value of leftor right side ,and with the change between the initial value and the stable value of TcPO2 (P<0.05 or P<0.01). The multiple linear regression analysis showed that SUA level was the impact factorof the left TcPO2 stable value. Conclusion HUA may be one of the risk factors microcirculation disorder in T2DM patients.

With the development of health care,medical x-ray equipments have been applied extensively.In order to avoid the harm of X-ray to patients,radioprotection must be paid more attention, and radiation dosage should be minimized.
9.Preparation and clinical application of HIV 60 mer oligo microarray
Medical Journal of Chinese People's Liberation Army 2001;0(07):-
Objective To prepare 60 mer oligo microarray chips for detecting human immunodeficiency virus (HIV) and for the clinical application in the detection of AIDS patient. Methods Oligonucleotide probes were designed according to the sequence information of two types of HIV. Oligo microarray was prepared by using Cartesian Microarrayer. Products of the restrictive display PCR were labeled with Cy3. Furthermore, the PCR products were sequenced. Results Using the oligo microarray, HIV infection could be detected in laboratory as well as in clinical assays. Results of hybridization indicated that 1 AIDS patient was positive and 20 health people were negative. The results obtained by sequencing confirmed the results obtained by oligo microarray studies. Conclusion The HIV 60 mer oligo microarray could be used in detecting patient HIV infection and analyzing its genotypes.
