Journal of Peking University(Health Sciences) 2004;0(02):-
Objective: T o further investigate pathogenesis about vulvovaginal candi diasis (VVC). Methods: Human normal vaginal epithelial cells in vitro were cultured by tissue cultur e and keratinocyto serum-free medium. Passaging epithelial cells were coculture d with candida albicans medium in separate wells for 0, 3, 6, 12, 24, and 48 h. C ontr ol epithelial cells were cultured alone in separate wells. For examination o f cytokines and chemokines, at each time point, the coculture supernatant and th e control culture were collected. ELISA was applied to detect the levels of HBD -1, HBD-2 and SP-A protein expression in the vaginal epithelial cells (HBD-1 :F= 62.784,P=0.001; HBD-2: F=5127.984, P=0.000; F=542.210, P=0 .000). Also, we colle cted the vaginal doughing water of VVC patients and healthy women, and detected the levels of SP-A, then analysed the data. Results: In the tra il of human vagin al epithelial cells, in contrast to the control group, the medium group induced the epithelial cells to secrete more HBD-1, HBD-2 and SP-A at h48, which was co nsidered to be significant (P

3.Determination of Plasma Sex Hormone Levels in the Male Patients with Gynecomastia
Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2001;30(1):36-38
In order to study the relationship between sex hormone and gynecomastia, the levels of plasma sex hormone in the male patients with gynecomastic were determined by using radioactive immune assay. Seventy-eight gynecomastic patients were regarded as the experimental group which was divided into 3 subgroups: the youth group with the age ≤30 years old, the middle-aged group with the age ranging from 30 to 60 years old and the old-aged group with the age ≥60 years old in the light of age and 24 normal men served as control group. The results showed that the levels of E2 and E2/T in the gynecomastia patients were much higher than in the control group (P<0.05, 0.01);In the experimental group, the ratio of T reduction in the old-aged group was much higher than in the youth group or the middle-aged group(P<0.05). In conclusion, gynecomastia was related to the dysfunction of the level of sex hormone, to a large extent, with the increasing of estrogen. In addition, senile gynecomasti was closely related with the decreasing of male hormone.

The tumor metastasis is the major cause of the death of cancer patients.S-100A4 is a member of the S100 family of calcium-binding proteins and has been categorized as a metastasis-associated protein.S-100A4 is a candidate as a molecular marker for metastatic potential with high prognostic significance.An increase in S-100A4 protein expression has been correlated with poor prognosis of patients with breast,colorectal,gallbladder,bladder,esophageal,nonsmall-cell lung,gastric,medulloblastoma,pancreatic and hepatocellular cancers.The overexpression of S-100A4 protein can induce the increase of invasion and mobility of the tumor cells.It has been considered that S-100A4 is secreted by the tumor and stroma cells as a regulator of tumor metastasis.S-100A4 can regulate the progress of cell cycle,change cell adhesion,cell mobility and increase the survival ability of the tumor cells.

Pubmed Database was undertaken to identify relevant articles of brain tumor stem cells published from January 2000 to January 2008. Books on stem cells and brain tumor stem cells were retrieved. The data were selected primarily, 39 articles related to brain tumor stem cells were selected. Of the 39 inclusive articles, 8 were on review of the brain tumor stem cells theory, 31 were about the research and experiment of brain tumor stem cells. Data synthesis shows that the CD133+ cells isolated from brain tumor have the stem cell-like properties of endless cell proliferation, uncontrolled self-renewal and multi-directional differentiation, but brain tumor stem cells have more vigorous capacity to increase than normal neural stem cells. The brain tumor stem cells express the same gene product as the normal neural stem cells, but the nuclear type of the brain tumor stem cells is abnormal. Brain tumor stem cells maybe the products of gene mutation from the normal neural stem cells. Brain tumor stem cells are the bad seeds of brain cancer, and play a key role in the progress of tumorigenesis, growth, invasion, metastasis, drug resistance and recurrence. Thus, studies on brain cancer stem cells have crucial effects on analyzing the mechanism of occurrence and development, as well as radical cure of brain tumor.

Cerebral ischemia represents one of the leading causes of death and disability in modern time, but only few options exist for the treatment of ischemia-related disease. Neural cell replacement can reconstruct the nerve conduction circuit unit and lead to functional recovery partly in patients. The mechanism lies in: the stem cells transplanted into the lesion can differentiate into functional glial cells or neurons, and they can substitute the functions of dead neurons; to activate the endogenous neural stem cells; to excrete cytokines and improve the local environments, such as inflammatory reactions, tissue necrosis and glial scar formation. Transplantation of bone marrow mesenchymal stem cells, umbilical cord blood, embryonic stem cells and adipose mesenchymal cells have been used for stem cells transplantation in treatment of cerebral ischemia in animal models. So far, the underlying mechanisms of the cell replacement therapy for stroke lesions have remained unknown, and this therapy faces predominantly two major problems: one is how cell grafts survive in an ischemic environment; the other is how cell grafts substitute or rescue neural cells with many different phenotypes.
