3.Mechanism of programmed cell death of renal proximal tubular cells induced by cisplation
Journal of Jilin University(Medicine Edition) 2006;0(04):-
Objective To study the signal pathway of apoptosis of renal proximal tubular cells (RPTC) caused by cisplatin for prevention of toxic effects of cisplatin on kidney. Methods pcDNA3.1/Hygromycin vector and pEGFP-C3 vector including Bcl-2(Bcl-acta,Bcl-cb5 and Bcl-nt) were co-transfected in RPTC.After treated with cisplatin, Bax was activated,cytochrom C release and apoptosis were analyzed with confocal microscope and immunofluoresence technique. Apoptotic cells stained with Hoechst33258 were also counted and statistically analyzed. Results The percent of cytochrom C release (35.74%) in Bcl-cb5 transfected group was higher than those in Bcl-nt group (18.7%) and Bcl-acta group(24.6%)(P
4.Advances in Neuroprotective Effects of Estrogen
International Journal of Cerebrovascular Diseases 2008;16(5):365-369
Most epidemiological investigations and basic studies have demonstrated that estrogen has neuroprotective effects,and the application of estrogen in cerebrovascular disease has a positive attitude.However,large clinical trials of the application of estrogen have indicated that harms outweigh benefits,and even have the risks of stroke.This article reviews the related studies about the neuroprotective effects of estrogen from the positive and negative aspects.

To investigate the role of ERC,6 gene in the growth rate and antifungal susceptibility,Aspergillus fumigatus strain with extra copies of ERG6 gene was constructed.Open reading frame (ORF) of putative ERG6 gene was searched in A.fumigatus genome.A PCR fragment, ERG6 ORF sandwiched by its flanking sequences (about 1 kb respectively),was amplified and was then subcloned into vector pRG-AMA1- NotI to produce a recombinant plasmid pERG6,which was further transformed into uracil auxotroph A.fumigatus strain AF293.1 to produce the transformant AF-pERG6.In the same time,empty plasmid pRG-AMA1-NotI was also transformed into A.fumigatus strain AF293.1 to produce the transformant AF-empty as a control.Radial growth of the transformants was tested on minimal medium (MM) and YAG medi- um.Antifungal susceptibilities of these resahing transformants,AF-pERG6 and AF-empty,to the common antifungal agents were performed by using both disk diffusion and broth microdillution methods.A.fumigatus genome contains a ERG6 gene,of which the ORF size is 1 256 bp.Comparing to Candida albicans and Sacchromyces cerivisiae sterol methyltransferase,A.fumigatus Erg6p had 57% and 50% identity, and had 70% and 63% similarity in amino acid sequences,respectively.Radial growth of transformant AF-pERG6 was slower than that of transformant AF-empty.The antifungal susceptibilties of transformant AF-pERG6 to the antifungal drugs itraconazole,voriconazole,terbin- aline,amphotericin B,caspofungin and grisefolvin were same to that of transformant AF-empty.In A.fumigatus,extra copies of ERG6 gene have no effect on antifungal susceptibilities to itraconazole,voriconazole,terbinafine,amphotericin B,caspofungin and grisefolvin.Radial growth of A.fumigatus harboring extra copies of ERG6 gene becomes slower compared to the control.

Objective To determine the key points in surgical treatment of Mirizzi syndrome in the olderlys. Methods Clinical data of 12 cases of Mirizzi syndrome treated in our hospital from 1995 to 2004 were retrospectively analyzed. Results Only 6 cases were definitely diagnosed by ERCP and ultrasounography before operations. Three cases were treated with cholecystectomy, 7 cases with cholecystectomy and T-tube drainage of common bile duct, 2 cases with cholecystectomy and Roux-Y hepaticojejunostomy. Conclusions It is still difficult to diagnose Mirizzi syndrome preoperatively. Appropriate operative patterns should be selected according to different types of Mirizzi syndrome.No patient death during operations.The patients were followed 1-10 years, average was 3.2 years. No bile duct stricture was found.

Hidden-pathogen theory is always a leading theory of febrile disease etiology from the proposal until the Ming Dynasty and it plays a critical guiding role on development and maturity of febrile disease theory. However, along with the change of times and drift of disease spectrum, this theory is facing unprecedented challenges. The gradually in-creased clinical experiences and facts have been difficult to be explained and induced using the already existed hidden-pathogen theory. Since hidden-pathogen theory has its own theoretical status and value, which cannot be lightly given up, the question of how to develop this theory in order to better reveal the pathogenesis in the guidance of diagnosis and treatment has become the focus of attention. This paper tried to proposeemotional hidden-pathogenas an example to provide a possible paradigm to develop hidden-pathogen theory and systematically expound main ideas and reasoning processes of emotional hidden-pathogen doctrine and to explore its theoretical significance and application value.

ObjectiveTo investigate the clinical features of cardiac involvement in polymyositis or dermatomyositis(PM/DM).MethodsAll articles published in Chinese and English were retrieved by searching the electronic resource databases.Theeligible articles that metthe predefined inclusion and exclusion criteria were included and then a systemic review was performed.ResultsTotally 23 articles were enrolled in this study,including 1452 patients.The incidence of cardiac involvement was 27.1%-85%.Heart failure was the most frequent (43.8%-76.9%) symptom.Among the abnormal ECG and UCG,the incidence of conduction abnormalities,left ventricular diastolic dysfunction andhyperkinetic left ventricular contraction 25%-38.5%,27.3%-51.5% and 11.5%-42.3% respectively.The pathological findings revealed myocardial inflamma-tion,degenerative changes and necrosis similar to those findings in skeletal muscles.Some patients'condition were improved aftergluco-corticoid stero and immunosuppressant treatment.Thirtypatients (30.9%) died as a direct result of heart disease.ConclusionHeart abnormalities are common in patients with PM/DM,most of them are subclinical,however.The efficacy of gluco corticoid steroid and immunosup-pressant treatment are uncertain.Cardiac involvement is a common cause of death.

ObjectiveTo investigate the therapentic effect and safety by use of Metoprolol to control patients ,heart rate in off-pump coronary artery bypass graft (OPCAB). MethodsAnalyse the dates of 40 OPCABG patients in anesthetic stage. ResultsIn all of the cases,when patients were treated with venous injection of Metoprolol, the heat rate obviously decreased 1 minutes later( P < 0.01 ). the heat rate decreased significant to( 69.2 ± 10. 8)times/min 3 minutes later, Compared to the heat rate ( 85.1 ± 13.5) times/min of pretherapy there was statistical significance. the heat rate decreased to nadir(63.0 ± 6.2) times/min 10 minutes later. While it raised gradnally 30 minutes later,but patients'heat rate nulli-exceed. it of pretherapy. On post-treatment of 3min、5min、 10min、30min, The MAP nulli-genic marked change. ConclusionMetoprolol could control effectively patients,heat rate in OPCAB and keep hemodynamics stable.
