2.Diagnosis value of serum mesothelin levels on epithelial ovarian cancer
Cancer Research and Clinic 2013;(4):287-288
Tumor markers for early diagnosis of cancer is an important auxiliary mean,which for early tumor detection,monitoring and for judging curative effect of treatment regimens play important role.Clinical method for early diagnosis on ovarian cancer is the detection of serum CA125,however,its precision and specificity for early diagnosis are not enough.It has been found that in the development period of the patients with ovarian cancer,SMRP and CA125 is co-expression.This article reviews the value of serum mesothelin on diagnosis of epithelial ovarian cancer to provide reference on early diagnosis and treatment.
3.Study on ATP bioluminescence in assaying the cleaning quality of uterine suction
Chinese Journal of Primary Medicine and Pharmacy 2013;20(14):2086-2088
Objective To explore the application value of ATP bioluminescence in assaying the cleaning quality of uterine suction.Methods According to the principle of random,we selected 120 uterine suction tube after use.60 used tubes in A group were given water immersion + high-pressure water jets wash + dry method,60 used tubes in B group were given alkaline cleaning solution soak + ultrasonic + high-pressure water washing + manual scrub + drying method.The quality of suction tube was initially tested with the visual method after cleaning,Straw inside the top cavity,2.5cm at inside straw joint and the front of straw outer wall,10cm at suction cavity wall,before and after cleaning the residues of bacteria were assayed with the ATP bioluminescence and bacteria counting method for parallel comparison.Results After cleaning drying program,the RLU of two groups in suction head internal top,2.5cm at inside straw joint,the front of straw outer wall,10cm at suction cavity wall had significant differences (t =26.81,29.13,7.14,55.74,P < 0.01).The cleaning effect of B group was better than A group..Bacteria counting method was used to detect pathogenic microorganism that was not detected.The qualified rate of cleaning at four parts was as following:group A:70.0%,85.0%,93.3%,93.3%.B group:95.0%,98.3%,100.0%,100.0%,and the qualified rate of group B was significantly higher than group A (x2 =12.99,6.98,4.14,4.14,all P < 0.05).Conclusion ATP bioluminescence method can dynamically rapid detect the bacteria before and after intrauterine suction cleaning residues,can be viewed as an effective method to detect quality of uterine suction cleaning.
4.Endovascular repair for retrograde type A aortic dissection with an entry tear in the descending aorta
Chinese Journal of General Surgery 2013;28(12):911-914
Objective To evaluate endovascular aortic repair for retrograde Stanford type A aortic dissection with an entry tear in the descending aorta.Methods From April 2006 to Dec 2012,31 patients with retrograde type A aortic dissection were treated with endovascular technique.22 patients had pleural effusion,14 patients had patent false lumen in the ascending aorta.Emergency operation was performed in 2 patients with acute right renal artery and right common iliac artery ischemia respectively.29 patients received endovascular treatment after 3 weeks conservative treatment.Chimney technique was used in 3 patients.Results All procedures were technically successful without severe complications.Ascending aorta recovered 1-3 months after operation.Pleural effusion subsided 3 days to 3 weeks after endovascular treatment.During follow-up of (31 ± 18) months,no severe complications developed,all the stent-grafts placed by chimney technique were patent.Conclusions Endovascular aortic repair can be used in the treatment of retrograde Stanford type A aortic dissection.Chimney technique can be used to reconstruct supra-aortic branches.
5.Cytochrome C、mitochondria and apoptosis
Chinese Pharmacological Bulletin 1987;0(03):-
There is an evidence that mitochondrial cytochrome C has dual functions in controlling both cellular energetic metabolism and apoptosis. Once released, cytochrome C, in interaction with apoptotic protease activating factors (Apaf 1), initiates the activation of the execution caspases that lead to the subsequent apoptosis. Release of cytochrome C is the result of a perturbation of mitochondrial membrane permeability. Anti apoptotic Bcl 2 family proteins function as gatekeepers to prevent the release of cytochrome C. In addition to cytochrome C, mitochondria release other apoptogenic proteins including apoptosis inducing factor (AIF) during apoptosis. These two pathways may work together to induce complete apoptosis. After transient cerebral ischemia, the release of cytochrome C occurs from mitochondria, preceding DNA fragmentation.
6.Changes of differentiation- and proliferation-related proteins in neural stem cells in rats treated with L-monosodium glutamate
Journal of Third Military Medical University 2003;0(17):-
Objective To investigate the roles of differentiation and proliferation related proteins in neural stem cells (NSCs) in rats treated with L monosodium glutamate (MSG). Methods Tissue proteins were extracted from the rat forebrain. Western blotting was used to investigate the changes of differentiation and proliferation related proteins in NSCs in rats treated with MSG. Results Compared with those in rats of the normal control group, the related proteins (Notch1, hes5, Mash1, and NeuroD) in NSCs were significantly decreased in MSG rats at 30 and 60 d, especially for Notch1 and hes5 ( P
7.Changes of differentiation and proliferation of neural stem cells in rats treated with corticosterone
Journal of Third Military Medical University 2003;0(17):-
Objective To explore the changes of differentiation and proliferation of neural stem cells in rats treated with corticosterone (CORT). Methods Adult SD rats were administered with CORT (10 mg?kg -1 ?d -1 ) by consecutive subcutaneous injection for 14 days. Single and double immunohistochemical stainings were used to identify the neural stem cells and differentiated neural cells in adult rats. Results Compared with that in the normal control group, the number of BrdU immunohistofluorescence positive cells and BrdU+NF200, BrdU+NeuroD, BrdU+GFAP double immunostaining positive cells in the cerebral cortex, hippocampus, and hypothalamus were markedly decreased ( P
