2.Discussion of some queries on the integrated management of rural health services
Chinese Journal of Hospital Administration 1996;0(04):-
The author expounds his views on some queries about the integrated management of rural health services. ①The prospective goal of the integrated management is not to solve problems in the internal reform of township public health centers, but to implement management of health services at the village level, a goal that can be attained. ②The structure of property rights of rural health institutions ought not to become the criterion of rural health reform; what should become the criterion ought to be the establishment of safe, effective, comprehensive, and non profitable health services. ③Concrete analyses should be made regarding the increase of charges for medical services after the integrated management. ④The integrated management means management based on integration, the latter being an indispensable means of the former. ⑤Perfection of the integrated management needs to go through a process.

4.The Development and Study of the Glucocorticoid Receptor Blockade Animal Model
Academic Journal of Second Military Medical University 1982;0(01):-
In order to study the physiological action of glucocorticoid receptor (GR) in intact animal, an animal model of GR depletion was developed in the rat by mifepristone (RU486), an antagonist of GR. Mifepristone 50 mg/kg body weight mixed in polyvinyl alcohol (PVA) was injected intramuscularly every 12 h in order to maintain the plasma mifepristone at the concentration of about 10-6mol/L for 72 h. In the meanwhile, the plasma corticosterone (B) was stabilized at about 15 ?g/dl by unilateral adrenalectomy 3 d before. In this model mifepristone occupied 88.1 ?10.7% of the total GR in hepatic, brain cytosol and thymocytes as measured by the exchange assay with [3H]dexamethasone (Dex) as ligand. Some indexes of glucocorticoid response were measured in the control, model and bilateral adrenalectomized (AdxT) rats. The polymorphonuclear eosinophil leukocyte (PME) count in blood and phospholipase A2(PLA2) activity in serum were decreased and tyrosine aminotransferase (TAT) activity of the liver was elevated in the control rats after stress provoked by epinephrine, but these changes were reversed in the model rats as well as in the AdxT rats. Thus it may be concluded that decrease of GR to about 12% may result in adrenoglucocorticoid insufficiency in spite of the normal functioning adrenal gland and high plasma level of B. So far as we know this is the first success to produce experimental endocrine insufficiency in a receptor depletion animal model and to quantitate the occupational threshold of about 12% of the total GR in rats.
5. A neuronal molecular switch through cell-cell contact that regulates quiescent neural stem cells
Journal of Shanghai Jiaotong University(Medical Science) 2019;39(4):339-341
The quiescence of radial neural stem cells (rNSCs) in adult brain is regulated by environmental stimuli. However, little is known about how the neurogenic niche couples the external signal to regulate activation and transition of quiescent rNSCs. Here, we reveal that long-term excitation of hippocampal dentate granule cells (GCs) upon voluntary running leads to activation of adult rNSCs in the subgranular zone and thereby generation of newborn neurons. Unexpectedly, the role of these excited GC neurons in NSCs depends on direct GC-rNSC interaction in the local niche, which is through down-regulated ephrin-B3, a GC membranebound ligand, and attenuated transcellular EphB2 kinase-dependent signaling in the adjacent rNSCs. Furthermore, constitutively active EphB2 kinase sustains the quiescence of rNSCs during running. These findings thus elucidate the physiological significance of GC excitability on adult rNSCs under external environments and indicate a key-lock switch regulation via cellcell contact for functional transition of rNSCs.
6.Functional analysis of platelet-derived growth factor-β receptor in self-renewal of neural stem cells
Chinese Journal of Neurology 2015;48(7):595-600
Objective To investigate the role of platelet-derived growth factor-β receptor (PDGFR-β) in self-renewal of neural stem cells (NSCs).Methods In this study,NSCs of subventricular zone were isolated and cultured from PDGFR-β knockout (PDGFR-β-/-) mice of postnatal day 1 (P1) and P28;the number and diameters of secondary neurospheres were calculated;using 5-bromo-2-deoxyuridine (BrdU) incorporation assay and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay,cell proliferation and survival rates were analyzed;gene expression profiles were determined by PCR-array analyses;the effect of brain-derived neurotrophic factor (BDNF) on secondary neurospheres formation was examined in these cells.Results In PDGFR-β-/-NSCs,stem cell activities,such as number (/well;P1:25.9±1.3vs117.6±3.6,t=4.236,P<0.01;P28:13.8± 0.7vs 19.8±0.6,t=2.116,P<0.01)and diameters (μm;P1:67.7±1.9 vs 69.1 ±2.0,t=3.211,P<0.01;P28:33.4±0.8vs37.8±0.8,t=2.354,P <0.01) of secondary neurospheres,cell proliferation (%;P1:73.3 ± 2.7 vs 88.7 ± 3.6,t =2.773,P < 0.05;P28:28.6 ± 9.6 vs 68.2 ± 4.5,t =6.302,P < 0.05) and survival rates (%;P1:14.5 ±2.1 vs 9.3 ± 1.3,t =7.222,P < 0.05),were significantly lower as compared with age-matched controls.In comparison of the same genotypic NSCs,the decrease of secondary neurosphere formation was more striking in P28 NSCs than in P1 NSCs.PCR Array analyses demonstrated that expressions of fibroblast growth factor2 and BDNF were decreased (-2.04 ± 0.25,t =2.653,P < 0.05;-3.24 ± 0.37,t =1.324,P < 0.05),and Noggin (2.31 ± 0.37,t =2.749,P < 0.05) was increased in P1 PDGFR-β-/-NSCs as compared with P1 controls.Addition of BDNF rescued the number and diameter of secondary neurospheres in P1 PDGFR-β-/-NSCs to similar levels as controls.Conclusions PDGFR-β signaling may play a role in the selfrenewal and proliferation of NSCs.BDNF may be involved in the effects of PDGFR-β signaling in these cells.

Chinese Journal of Digestive Surgery 2015;14(11):971-974
Liver cancer is one of the most common cancers worldwide and the third leading cause of cancer death.Partial hepatectomy and liver transplantation are the most effective therapies.However, postoperative tumor metastasis and recurrence are the main obstacles in the long-term survival.Liver cancer stem cells (LCSCs) within cancer tissues are associated with tumor occurrence, proliferation and tolerance to current therapy and are regarded as the major root of metastasis and recurrence.Eradication of LCSCs is a novel therapy of liver cancer.In this review, surface markers of LCSCs and mechanisms of pro-metastasis and recurrence, circulating LCSCs,microenvironment of LCSCs and their roles in the metastasis and relapse are summarized.
