3.Chromosome 3p tumour suppressor genes and clear cell renal cell carcinoma
Journal of International Oncology 2012;39(1):60-63
The abnormal changes of tumor suppressor genes such as deletion mutant,transcription inactivation or silence on human chromosome 3p (pter) are considered as a key step which is closely related to the tumorigenesis of several kinds of cancers,especially clear cell renal cell carcinoma,one kind of renal cancer.And on this basis,it has been confirmed that the deletion and downregulation of multiple 3p genes such as VHL,RASSF1A,SEMA3B,SETD2,PBRM1,NPRL2 and so on,play a vital important role in the tumorigenesis and development of clear cell renal cell carcinoma.And they provide a further way to explain the molecular mechanism of the tumorigenesis of kidney cancer.However,when the regulatory pathway and mechanism research of some genes are known to us,the other genes,especially those newly founded,which are still not clear and need to be further investigated.
4.Etiologic classification of ischemic stroke
International Journal of Cerebrovascular Diseases 2011;19(7):535-538
Etiologic classification of ischemic stroke is the basis for epidemiological investigation, risk factor screening developing individualized treatment plan and prognostic measures. The etiologic classifications, such as TOAST, CCS, and ASCO, are more generally accepted methods at present. This article reviews the advantages and disadvantages from the diagnostic criteria and clinical application.
5.Progress of behavioral tests in rat models of Parkinson’ s disease
Acta Laboratorium Animalis Scientia Sinica 2015;(2):209-215
Parkinson’ s disease ( PD) is a neurodegenerative disorder primarily characterized by resting tremor, muscular rigidity, akinesia and postural reflex impairment.Behavioral tests of PD in animal models are essential for under-standing the pathogenesis of PD as well as for the development and testing of potential therapeutics .Here we mainly use the 6-hydroxydopamine (6-OHDA)-induced rat model, to introduce a review on the research progress in non-drug-induced be-havioral tests of motor function in PD rats.
6.Ischemic stroke subtype classification: a comparative study of ASCO, CISS and TOAST
International Journal of Cerebrovascular Diseases 2013;21(6):430-434
Objective To investigate the differences in the clinical application of the etiological subtypes of ischemic stroke according to the TOAST,ASCO and CISS criteria.Methods A total of 167 consecutive patients with fist-ever ischemic stroke were enrolled in the study.They were classified with the TOAST,ASCO and CISS criteria,respectively.The differences and consistency of subtype diagnosis of each etiology were compared.Results Compared with TOAST,ASCO grade 1 significantly increased the proportion of patients in a large atherosclerosis group (23.4% vs.19.8% ;x2 =4.167,P =0.031) and decreased that in a small vessel disease group (32.9% vs.38.3% ; x2 =4.923,P =0.022); similarly,CISS also significantly increased the proportion of patients in the large atherosclerosis group (37.1% vs.19.8% ;x2 =27.034,P <0.001)and decreased that in the small vessel disease group (19.2% vs.38.3%;x2=25.289,P < 0.001).However,ASCO grade 1 (34.1% vs.28.1%;x2 =3.682,P=0.052) and CISS (32.9% vs.28.1%;x2 =0.880,P =0.268) did not decrease the proportion of patients in a cryptogenic group.The consistency of the 3 typing methods was between moderate (other etiology group of TOAST/ASCO-1,κ =0.434) and excellent (cardioembolism group of TOAST/ASCO-1,κ =0.967).Conclusions Both ASCO-1 or CISS typing may not decrease the proportion of the patients with the subtype of cryptogenic stroke,but the consistency among all the subtypes was better.The design and characteristics of the diagnostic criteria in all subtypes with the 3 criteria should be considered in clinical practice.
7.Sequence analysis of beta 1,3-galactosyltranferase specific molecular chaperone Cosmc gene coding region in IgA nephropathy patients
Chinese Journal of Tissue Engineering Research 2007;0(21):-
BACKGROUND: Pathogenesy of immunoglobulin A nephropathy (IgAN) is not clear up to now. Present research has verified that the key pathogenetic pathway is abnormalities of IgA1 molecular O-glycosylation induced by decrease of ?1,3-galactosyltranferase activity in IgA1 hinge region of IgAN patients. Prophase study by the authors supposed that the key of IgAN O-glycosylation abnormality might be due to the decrease of ?1,3-galactosyltranferase specific molecular protein chaperone Cosmc in B lymphocyte of peripheral blood in IgAN patients. OBJECTIVE: To measure DNA sequence of ?1,3-galactosyltranferase specific molecular chaperone in coding region of Cosmc gene in IgAN patients,and compared with the sequence of Gene Bank. DESIGN: Case-controlled observation. SETTING: Department of Nephrology,West China Hospital,Sichuan University. PARTICIPANTS: Totally 27 IgAN patients and 10 non-IgAN patients were recruited in Department of Nephrology of West China Hospital of Sichuan University from November 2005 to August 2006,and five normal controls were included in this study. All the subjects knew the fact and agreed to participate in the experiment. METHODS: The experiment was performed at the State Key Laboratory of Biotherapy of Sichuan University. 2 mL peripheral venous blood of all the samples were taken into heparin sodium anticoagulated tubes,from which total genomic DNA were extracted by phenol/chloroform precipitation method. Concentration of DNA was determined by ultraviolet spectrophotometer. The polymerase chain reaction (PCR) was used to amplify the coding region of ?1,3-galactosyltranferase specific molecular chaperone Cosmc gene in all the subjects and direct sequencing was done in PCR products of each subjects. The results of all the sequencing were compared with Gene Bank one by one. MAIN OUTCOME MEASURES: Amplification findings and sequencing of coding region of ?1,3-galactosyltranferase specific molecular chaperone Cosmc gene by PCR. RESULTS: ①Coding region of Cosmc gene located at 257-1 213,and amplified Cosmc gene was 1 247 bp. ②The sequence of Cosmc gene coding region was similar in IgAN patients,non-IgAN patients and normal controls,and no difference of gene sequence was noticed in all the result sequences as compared with the Gene Bank registered sequence. CONCLUSION: No abnormal sequence is found in coding region of Cosmc gene in IgAN patients,suggesting that this coding region probably is not associated with the abnormalities of IgA1 O-glycosylation in IgAN.

Journal of Interventional Radiology 2001;0(06):-
Objective To investigate the value of transcatheter arterial embolization in the treatment of obstinate nosebleeding. Methods Twenty patients with obstinate nosebleed failed with conventional therapy were performed internal maxillary arterial angiography. Transcatheter arterial embolization were carried out immediately after occurance of nosebleeding. PVA or gelfoam particles were injected into the bleeding arteries under fluoroscopy control. Nasal packing was removed to see whether bleeding was stopped. Results Active bleeding occurred in all 20 patients during angiography but was stopped in all patients after embolization without severe complications. Conclusions Transcatheter arterial embolization is an useful mini-invasive method in the treatment of obstinate nosebleeding.
