Chinese Journal of Primary Medicine and Pharmacy 2011;18(7):909-910
Objective To explore the correlations between the levels of glycosylated hemoglobin A1c (HbA1c)and N-Terminal pro-Brain Natriuretic peptide(NT-proBNP)in aged diabetes mellitus(DM)patients with heart failure(HF).Methods 127 patients diagnosed as DM complicated by HF and detected HbA1c and NT-proBNP when admitted into hospital,were divided into three groups according to the levels of HBA1C as follows:group A,4%≤HbA1c≤6.9%;group B,7%≤HbA1≤7.9%;group C,HbA1c≥8%.The levels of NT-proBNP were measured and compared.Results There was no statistical difference between group A and B(P>0.05),where as the levels of NT-proBNP in group C increased significantly than that in group A and B(P<0.01);In group C,HbA1c was linear positively correlated to NT-proBNP(r=0.558,P<0.01).Conclusion Aged DM patients complicated by HF,the level of HbA1c between 4%and 7.9%was acceptable.Meawhile,HhA1c should the independent risk prediction factor for aged DM patients complicated by HF,which could be used as the guide to the clinical therapy to improve the prognosis.
2.Expression of novel gene SNC66 in gastric cancer tissue and normal gastric mucosa
Chinese Journal of Pathophysiology 1986;0(04):-
AIM: To study the expression level of gene SNC66 in gastric cancer tissues, and investigate the relationship between the expression of SNC66 and the pathogenesis of gastric cancer.METHODS: Paired normal and cancerous paraffin-embeded tissues from 20 gastric cancer patients were tested by in situ hybridization (ISH) and in situ reverse transcription and polymerase chain reaction (ISRT-PCR)using ?-actin as a control.RESULTS: ISH and ISRT-PCR both showed that SNC66 were all strong positive expressed in 20 normal gastric mucosa.But in 20 gastric cancer tissues,the ISH showed that 8 were negative,8 were weak positive and 4 were strong positive. The ISRT-PCR showed that 6 were negative,9 were weak positive and 5 were strong positive when the PCR cycled 10 times;4 were negative and 16 were strong positive when the PCR cycled 25 times. CONCLUSION: There was significant expression reduction or defect of SNC66 in gastric cancer tissues.SNC66 should be further investigated as a gastric cancer negative relative gene.
3.The research status of preclinical animal experiments of gene therapy for Leber congenital amaurosis
Chinese Journal of Experimental Ophthalmology 2014;32(8):764-768
Leber congenital amaurosis (LCA) is extremely severe hereditary retinal dystrophy,because it leads to congenital bilateral blindness in early childhood.With the development of molecular genetics and the therapeutic gene replacement technology,gene therapy clinical trials have obtained exciting results on the basis of relatively satisfied with preliminary clinical experimental results by adeno-associated virus (AAV) vector-mediated gene therapy in the past decade.These researching methods include intravitreal injection and subretinal space injection of gene vector,and the investigating indexes include evaluations of visual function and safety,such as immune reaction of the animals,ocular histopathological change,complications and bio-distribution of gene sequence.The preliminary success of the LCAⅡ Ⅱ gene therapy will give some clues to the other inherited retinal diseases.This review focuses on the present status of pre-clinical animal experiments of its gene therapy.
5.Advance in Proteomics Analysis of Multiple Sclerosis (review)
Chinese Journal of Rehabilitation Theory and Practice 2008;14(1):38-40
Proteomics analysis of multiple sclerosis will provide more molecular pathology information about it.With appropriated methods of sample preparation,protein separation and identification,some proteins related to multiple sclerosis could be found and helpful for diagnosis,treatment and prophylaxis.This will improve the final diagnosis ratio of suspected cases and offer clue of drug and gene therapy exploration.Intervention of the related protein ameliorate symptom and release relapse.
6.Application development of rapid prototyping technology in orthopedics
International Journal of Biomedical Engineering 2009;32(6):375-378
Rapid prototyping technology, a kind of novel digital prototyping technology developed in mid-1980s based on a principle of discrete and accumulation, which fabricates a prototype by accurate accumulation of material according to the CAD models or CT data under the control of the computer without any other device. In recent years, it has shown a great application prospect in the field of orthopedics combined with three-dimensional image reconstruction of spiral CT and MRL In this article, review is given on the application development of rapid prototyping technology in orthopedics, such as organ model preparation and surgical planning, customized implant and bone tissue engineering porosity scaffold fabrication.
7.Imaging Evaluation of Carotid Stenosis
International Journal of Cerebrovascular Diseases 2008;16(6):452-455
Carotid stenosis is an important modifiable risk factor in ischemic stroke.The com prehensive diagnosis of carotid stenosis,including the comprehensive understanding of stenosis degree,plaque stability,and head and neck vessels,which has important guiding significance for the prevention and treatment of ischemic stroke.This article reviews the diagnostic values of digital subtraction angiography,sonography,magnetic resonance angiography and CT angiorgaphy in carotid stenosis.
8.Preoperative and postoperative prognostic indicators of recurrence of hepatocellular carcinoma following liver transplantation
International Journal of Surgery 2010;37(8):557-561
Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.
9.Determination of Dextrorphan in Human Liver Microsomes by LC-MS/MS
Herald of Medicine 2016;35(6):578-582
Objective To establish a liquid chromatographic-mass spectrometric method ( LC-MS/MS method ) for determination of dextrorphan in human liver microsome. Methods LC-MS/MS was adopted with carbamazepine serving as an internal standard.The separation was performed on Agilent ZORBAX XDB-C18 column (2.1 mm×50 mm, 3.5μm), with mobile phase consisting of 0. 05% formic acid methanol-0. 05% formic acid in gradient elution. Dextrorphan and carbamazepine were detected on multiple reaction monitoring(MRM)mode by transitions from precursor to production(m/z 258.1→199.1, 237.1→194.1). Results The linear range of dextrorphan concentration was 19.22-768 960 ng.L-1(r=0.999 8), and the lowest quantification limit was 19.22 ng.L-1.The relative recoveries were 94.02%-98.74%, and the RSDs of intra-day and inter-day were within 10%.IC50 of psoralen on CYP2D6 was 0.6μmol.L-1. Conclusion The LC-MS/MS method is proved to be rapid, sensitive and reproducible, psoralen is a strong inhibitor of CYP2D6.
