2.Comparison between old and new clinical staging of primany liver cancer
China Oncology 1998;0(01):-
Purpose:To compare old and new clinical staging of primary liver cancre. Methods:317 cases of primary liver cancer(PLC) patients,hospita lized and dead,were investigated retrospectively for overall median survival and survival after various therapies,according to various stages,and therapies and comparison among groups and test of median survival were carried out. Results:Survival in patients with new stage Ⅱa+Ⅱb or old Ⅱw ere significantly longer than newⅢa+Ⅲb or oldⅢ, but no significant differenc es were observed between new stageⅡa+Ⅱb and oldⅡ , or new stage Ⅲa+Ⅲb and oldⅢ. Median survival by new staging , decreased in peoper order from stageⅡ a ,Ⅱb , Ⅲa to Ⅲb respectively, significant different was found only between s tage Ⅲa and Ⅲb but not betweenⅡa andⅡb . Survival decreased respectively fr om interventional treatment ,systemic chemotherapy and palliative therapy;the in terventional treatment group did much better than the palliative group but no si milar differences were observed in the other groups. Conclusions:New clinical staging of PLC did not show significan t superiorly over the old one as judged by median survival.It can be questioned whether basing on largest diameter is less than 5/10 cm or more than 10 cm to di stinguish Ⅱa and Ⅱb is valid.Interventional treatment should be applied as soo n as possible to prolong survival whether it be the new or old clinical staging.
3.Determination of Anthranilic Acid in the leaves of Isatidis indigotica by First Order Derivative UV Sperctrophotometry
Chinese Traditional and Herbal Drugs 2000;31(9):664-665
Anthranilic acid in the leaves of Isatidis indigotica Fort. was determined by first orderderivative UV spectrophotometry. The average recovery was 96.66% and the coefficient of deviation was1.09%. The method showed no significant difference as compared with high performance capillary elec-trophoresis at 95% confidence level. The method is simple, rapid and accurate.
4.Research progress of acidic leucine-rich nuclear phosphoprotein 32E
Journal of International Oncology 2011;38(4):246-247
Acidic leucine-rich nuclear phosphoprotein 32E (ANP32E) belongs to a family of acidic nuclear phosphoprotein 32, and participates in a broad range of biological processes. ANP32E is similar to ANP32A in structure. It has been suggested that the nueleo-cytoplasmic shuttling might be regulated by phosphorylation. ANP32E is able to inhibit the activity of PP2A. Recent findings indicate ANP32E acts as a tumor suppressing gene in mice fibrosarcoma, and is correlated with lung metastasis in the tumorigenesis of breast cancer. But the mechanism is not yet clear.
5.Inhaled glucocorticoids and osteoporosis
Chinese Journal of Tissue Engineering Research 2005;9(3):252-253
OBJECTIVE:Inhaled glucocorticoids(GC) are the first-line medicine for bronchial asthma during relieve phase, thereby this study was designed to explore if patient tends to suffer osteoporosis due to long term inhalation of glucocorticoids. DATA SOURCES:Literatures about GC and osteoporosis were computer-searched in Medline and Embase from January 1980 to December 2003, with the key word of " asthma, bone density, bone metabolism and inhaled glucocorticoids" and language limited to English.Meanwhile it was also computer-searched in CBM, CBM disc and manually searched in Chinese Journal of Clinical Rehabilitation between January 1990 and April 2004 with language limited to Chinese. DATA SELECTION: Literatures about the comparison of bone density and bone metabolic change between inhaled GC group and control group were consorted deleting randomized controlled trial(RCT) so as to look up the whole content of healthy controls;While patients in the treatment group received GC inhalation.Exclusive standards:obvious non-RCT. Quality assessment is mainly focused on the reality of data,the strictness of design and implementation,and the rationality of statistical management. DATA EXTRACTION:Totally 30 randomized and nonrandomized studies about the influence of inhaled GC on the bone density and bone metabolism of patients with asthma were referred to amongst which 18 studies were admitted with the other 12 excluded for similarity in content in 8 and Meta-analysis in 4. DATA SYNTHESIS:A total of 1 153 asthmatic patients in 18 studies were divided into GC inhalation group and non-inhalation control group for comparing the difference of bone density and/or bone metabolism between them. CONCLUSION:Although the results of studies on the influence of long-term inhaled GC on bone quantity were different, but there was still not enough evidence to demonstrate that osteoporosis was due to long-term GC inhalation.
6.Role of estrogen receptor alpha in adipocytes differentiation of rat bone marrow mesenchymal stem cells
Journal of Practical Stomatology 2009;25(6):794-797
Objective; To elucidate the mechanism of the role of ER-a in fat metabolism by regulating the expression of ER-a in SD rats marrow mesenchymal stem cells during differentiating into adipocytes in vitro. Methods ;SD rats marrow mesenchymal stem cells were separated and cultivated. The ER-a was transfected into the rBMSCs in group one. Tamoxifen Citrate was used to restrain the expression of ER-a in group two, the group without any treatment was used as control. Western blot was used to identify the difference of ER-a expression among different groups and Oil-Red-0 staining was employed to identify the adipocytes in vitro. Results; There was significant difference between the number of lipids and different groups (P <0. 01) ,the number of lipid droplet changed concomitantly with ER-a: Low-expression ER-a group > Control group > High-expression ER-a group. Conclusion; ER-a in SD rats marrow mesenchymal stem cells may restrain the adipocyte differentiation.
7.Advances on mechanisms of multidrug resistance of tumors
International Journal of Pediatrics 2011;38(6):595-598
The development of multidrug resistance (MDR) to chemotherapy remains a major trouble in the treatment of tumors,and the mechanisms of MDR are complicated.The classic mechanisms involve the overexpression of multidrug resistance-associated protein,inhibition of cell apoptosis,abnormality of enzyme system and gene repair.Studies in recent years have shown that the mechanisms of MDR are also closely related with tumor stem cells,tumor microenvironment and abnormality of signal transduction pathways.
8.Relationship between transforming growth factor-?_1 signal transduction and renal fibrosis of diabetes
Chinese Journal of Clinical Pharmacology and Therapeutics 1999;0(04):-
Diabetic nephropathy is one of the leading causes of the end-stage renal failure, and its major pathologic feature is the renal fibrosis. Transforming growth factor-?_1 is a key factor in the progression of the disease. Two signal pathways, Smads and MAPK following the factor, are closely connected with extracellular matrix accumulation which leads to renal fibrosis. Smads and MAPK also have a cross talk in extracellular matrix accumulation. The relationship between the two signal pathway and ECM accumulation offers us a new therapeutic strategy for renal fibrosis of diabetes.
9.Relation of condylar morphology with different vertical facial types in the development of patients with skeletal Ⅲ malocclusions
Journal of Practical Stomatology 2000;0(06):-
Objective: To study the relation of condylar morphology with different vertical facial types in the development of patients with skeletal Ⅲ malocclusions. Methods:180 cases with skeletal Ⅲ malocclusion were divided into children(5-11 years old), adolescence(12-17 years old) and adult(18-30 years old) groups with 60 cases in each group. Orthopantomograms of the patients with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Condylar morphology were compared among different age groups of the same vertical facial type. Results:In patients with high angle, ramus height(RH) was getting bigger with ageing(P0.05). In patients with low angle h and RH in adult group were bigger than those in adolescence or in children(P
10.Microglia in pathogenesis of amyotrophic lateral sclerosis
Academic Journal of Second Military Medical University 1982;0(02):-
Amyotrophic lateral sclerosis is a chronic neurodegenerative disorder characterized by selective death of motor neurons and progressive paralysis. Many hypotheses have been proposed to explain its pathogenesis. In recent years,one of the most studied hypotheses was the inflammatory response accompanying the motor neuron death. Microglia and its interactions with motor neurons play important roles in the development and progression of the inflammatory responses and the disease itself,which results in different new and potent therapeutic strategies of great clinical value.
