1.On the Ethical Problems in the Use of Medical Information and Relevant Countermeasures
Chinese Medical Ethics 1995;0(02):-
When seen from the practice and development of modern medicine,we are facing challenges from various ethical problems which arise from the progress of life support technique,industry and network technique and its application in medicine,life sciences and electronic sciences.Nowadays,the legislation of medical ethics and regulations have become a heated issue drawing the attention of doctors,pharmacists,laboratorians,nurses,medical information staff,religions personnel,philosophers,medical scientists,and lawyers.This thesis tries to analyses the main ethical problems in the use of medical information so as to justify potential eligible ethical norms in clinical practice,expecting to draw the attention of relevant staff and general public and the fulfillment of ethical norms in the medical practice.
2.Investigation of Clinical Use of Xingnaojing Injections in Inpatients
Herald of Medicine 2017;36(1):84-87
Objective To investigate the application of xingnaojing injections ( XNJI) in inpatients and further provide a reference for the rational drug use. Methods The retrospective investigation was carried out by reviewing 186 hospitalization records with XNJI from a certain hospital from January 2014 to June 2015. The usage, dosage, and indication of XNJI were analyzed. Results Unlabeled use of XNJI was found in the neurology department inpatients. 59. 7% inpatients were treated with overdosed XNJI, and 13. 4% were treated with a single drug dose of 40 mL. The inappropriate solvent selection accounted for 49. 5%. Compatibility of XNJI and western medicine injection accounted for 54. 8%. It was also found that XNJI was used together with potassium chloride in clinic (47. 8%). Conclusion There exist some irrational uses of XNJI in clinic, thus the use and management of traditional Chinese medicine injections should be standarized.
6.A Novel Method for Multi-channel Neuronal Spike Detection and Classification
Progress in Biochemistry and Biophysics 2006;0(05):-
The detection and classification of extracellular action potentials(i.e.spike) of various single neurons from extracellular recordings are crucial for extracting neuronal spike sequences and thereby for investigating the mechanisms of neural information processing in the central nervous system.In order to increase the correctness of spike detecting and sorting,a new analysis algorithm for processing multi-channel spike signals recorded from rat hippocampi with silicon microelectrode arrays is presented.Four recording contacts on the electrode array are arranged close enough to simultaneously record spikes emitted from same neurons.Firstly,the algorithm extracts all spikes in the four channel recordings by using a multi-channel threshold detection method.Secondly,the algorithm classifies the spikes based on a principle component analysis for a specifically designed type of compound spike waveforms.The compound spike waveform is formed by linking four spike waveforms of a same neuronal firing in the four recording channels one by one in series.The test results with both synthetic datasets and experimental recordings reveal that compared with corresponding traditional single-channel algorithm,the multi-channel algorithm can significantly enhance both the number of extracted spikes and the correctness of spike classifications.The algorithm can also increase the number of isolated neurons from a single experimental preparation.These results indicate that the novel method is efficient for the automatic detection and classification of neuronal spikes.
7.The protective effect of Danggui Buxue decoction on radiation injury in mice
Chinese Journal of Comparative Medicine 2015;(10):55-58
Objective To observe the protective effect of Danggui Buxue Decoction on 60 Co-γray irradiated mice. Methods The experimental mice were randomly divided into 5 groups ( the normal control group , model group , Danggui Buxue Decoction of low , middle and high dose groups ) .The mouse except the normal control group were irradiated by 60Co-γray and established the radiation-damage model.Peripheral blood neutrophil count (NEUT), the number of bone marrow nucleated cells ( BMC ) , the activity of serum superoxide dismutase ( SOD ) and the serum levels of malondialdehyde ( MDA) were measured .Results Radiation injury in mice of NEUT , BMC and SOD were significantly decreased (P <0.01), MDA were increased (P <0.01).Danggui Buxue Decoction can increase the levels of NEUT , BMC and SOD in mice after radiation injury , decrease the content of MDA .And protective effect of high dose group was better (P <0.01).Conclusions Danggui Buxue Decoction has protective effect on radiation injury in mice .And there is a correlation between the protection effect and dose .
9.Associations of JAK1 gene polymorphisms with allergic rhinitis in Chinese Han populations.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(19):1713-1722
OBJECTIVE:
The aim of this study was to investigate the association of JAK1 polymorphisms with allergic rhinitis in China Han population.
METHOD:
A total of 450 patients with AR and 615 healthy subjects as control were genotyped for the presence of three single nucleotide polymorphisms using polymerase chain reaction restriction fragment length polymorphism (PGR-RFLP) analysis of DNA extracted from blood samples.
RESULT:
All control subjects were in Hardy-Weinberg equilibrium, but high frequencies of JAK1 the homozygous rs310241 CC genotype were observed in AR patients compared to controls (P < 0.05). The results also revealed that there was no association between the rest of two investigated SNPs and AR.
CONCLUSION
Our results suggested that JAK1 gene rs310241 CC genotype was associated with patients with AR.

10.Effects of ?-lipoic acid on cerebral IRE1 expression induced by sleep deprivation in rats
Academic Journal of Second Military Medical University 1985;0(05):-
Objective:To observe the influences of sleep deprivation and antioxidant agent ?-lipoic acid on the expression of IRE1 in the cortex and hippocampus in rats.Methods:Rats were randomly divided into control groups and sleep deprivation group.The control groups included blank control group(n=10) and environmental control group(n=10).Sleep deprivation group included 120 rats,and rats were further divided into ?-lipoic acid group(25 mg?kg-1?d-1) and sleep deprivation model group.The two were further divided into 6 groups according to the periods of sleep deprivation and sleep restoration(SD 1 d,SD 3 d,SD 5 d,SD 7 d,SD 7 d/RS 6 h,SD 7 d/RS 12 h[n=10]).The expression of IRE1 mRNA and protein was examined by RT-PCR and immunohistochemistry,respectively.Results:RT-PCR results showed that the expression of IRE1 mRNA in the cortex and hippocampus were significantly higher in sleep deprivation group than in the blank and environmental control groups(P
