1.DETECTION OF IDDM SUSCEPTIBILITY IN SHANGHAI HANS WITH HLA-DQA, OLIGONUCLEOTIDE PROBES
Chinese Journal of Endocrinology and Metabolism 1986;0(04):-
With polymerase chain reaction and dot-blot hybridization with allele-specific oligonucleoade probes,we analyse DQA1 gene of 42 insulin-dependent diabetes mellitus (IDDM) and 40 normal controls (the Han nationality in Shanghai). We found that the frequency of DQA1 * 0301 and DQA1 * 0501 allele in IDDM patients was greatly increased, while the frequency of DQA1 * 0103 and DQA1 * 0201 allele was significantly decreased as compared with the controls. The result indicates the contribution of the DQA1 * 0301 and DQA1 * 0501 alleles to IDDM susceptibility in Han population in Shanghai. Our results also provide confirmation of the role of DQA1 * 0103 and DQA1 * 0201 to IDDM resistance in the same population.

Chinese Journal of Behavioral Medicine and Brain Science 2016;25(9):784-790
Objective To explore the test-retest reliability of elevated plus maze (EPM) which is taken as an animal model of state anxiety in Kunming mice.Methods The behavior of adult,male and female,Kunming mice in EPM was recorded twice with one-week inter-trial interval for lasting five minutes.The following parameters were evaluated:percentage of time on EPM open arms (Otime%),percentage of time on EPM closed arms (Ctime%),time on EPM open arms (Otime),time on EPM closed arms (Ctime),percentage of entries into EPM open arms (Oentries%),entries into EPM open arms (Oentries),entries into EPM closed arms (Centries),total entries into EPM open and closed arms (Entries).Subsequently,the intraclass correlation coefficient (ICC) and the kappa agreement index (κ) were calculated for these parameters.Results ICC for Otime% (♂ ICC=0.506,P<0.05;♀ ICC=0.456,P<0.05;♂ + ♀ ICC=0.492,P <0.01),Oentries (♂ ICC=0.673,P<0.01;♀ ICC=0.648,P<0.01;♂ + ♀ ICC=0.665,P<0.01),Centries (♂ ICC=0.704,P<0.01;♀ ICC=0.661,P<0.01;♂ + ♀ ICC=0.686,P<0.01),Entries (5 ICC=0.701,P<0.01;♀ ICC=0.661,P<0.01;5 + ♀ ICC=0.685,P<0.01) showed a fair test-retest reliability,respectively.Only κ for Entries (♂ κ=0.253,P<0.05;♀ κ=0.339,P<0.05;♂ + ♀ κ=0.298,P<0.01)displayed a significant but poor reliability between the test-retest trials.Conclusion The Otime% Entries parameters as an acceptable index for Kunming mice in EPM can be used for exploratory and locomotion activity.Sex and repeated measurement have different effects on the Otime% and Entries parameters,especially the more on the former.Therefore,Otime% and Entries can be considered when EPM as an animal model of state anxiety in Kunming mice;meanwhile,more attention should be paid to both the sex (male animals recommended to EPM,especially) and repeated measurement effects.
4.Acupuncture Treatment Ideas of Allergic Rhinitis from the Perspective of“Fluid Retention ;Disease”in TCM
Chinese Journal of Information on Traditional Chinese Medicine 2017;24(2):114-116
Abstact: Biqiu is equivalent to allergic rhinitis in modern medicine. Ancient and modern literature has shown that acupuncture has a good clinical efficacy on this disease. However, there is no uniform specification in the choice of acupuncture methods (such as acupuncture, moxibustion, warm acupuncture and so on) and the selection of acupoints. According to the etiology and pathogenesis of allergic rhinitis and its clinical manifestations, Biqiu can be classified as“fluid retention disease”in TCM. This article tried to provide a new idea for acupuncture treatment of Biqiu from the perspective of the treatment of“fluid retention disease”in TCM.
5.Association between Presenilin 1 gene methylation and sporadic Alzheimer's disease
Chinese Journal of Geriatrics 2014;33(12):1272-1275
Objective To investigate the correlation between Presenilin 1 gene methylation (PSEN1) and sporadic Alzheimer's disease (SAD).Methods Massarray method was used to perform an analysis of DNA methylation in the promoters of PSEN1 gene in lymphocytes from 35 SAD patients,33 mild cognitive impaired (MCI)patients and 22 age-and gender-matched controls.Reporter gene plasmid of PSEN1 was built by genetic recombination methods,and then transiently transfected into the SH-SY5Y and HeLa cells.After that,cells were treated with several agents including serum deprivation,Aβ25-35,5-aza-2'-deoxycytidine (5-aza Cdr) and S-adenosyl-Lmethionine (SAM).A dual-luciferase reporter assay system was used to calculate the relative luciferase activity (RLA).Results Some CpG sites of PSEN1 (Cytosines at-173,95 and +76) showed hypomethylation patterns in SAD cases as compared with MCI and control group (P<0.01).A dual-luciferase reporter assay showing significant differences in PSEN1 transcription activities were found in both cell lines under SAM treatment [SY5Y,SAM:(6.40±0.81),control:(9.13±1.67),P=0.000; Hela,SAM:(2.06±0.34),control:(2.99±0.59),P=0.000].Conclusions DNA hypomethylation of PSEN1 gene promoter is significantly associated with SAD susceptibility.PSEN1 may change the gene transcription level by methylation,further affecting the activity of amyloid protein-like γ-secretase,leading to the onset of AD.

China Journal of Chinese Materia Medica 2014;39(20):4013-4019
The diarrheal rat model was established by orally administering senna. The preventive experiment was concurrent for 6 days. The treatment experiment modeling had lasted for 12 days. The administration started at the 7th day, and lasted for 6 days. During the experiment, efforts were made in symptom score and weighing. After the experiment, hearts, livers, spleens, kidneys, brains, adrenals and thymuses were collected and weighed, lactic dehydrogenase (LDH) and cardiac troponin-I (cTn-I) in serum were detected. The efficacy of aqueousextracts from Aconiti Lateralis Radix Praeparata in preventing and treating rats with diarrheal and its accompanying toxicity were respectively studied. The result shows that aqueous extracts from Aconiti Lateralis Radix Praeparata could improve syndromes of rats with diarrheal. The 50% effective doses (ED50) of preventive and treatment administrations were 1.420 4 g · kg(-1) and 1.048 9 g · kg(-1), respectively. Aqueous extracts from Aconiti Lateralis Radix Praeparata could decrease the ratio of heart to body weight, and increase serum LDH and cTn-I. It was concluded that aqueous extracts from Aconiti Lateralis Radix Praeparata had a specific preventive and treatment effect on rats with diarrheal caused by senna, but with specific toxicity on heart.
