In the opinion of dialectical materialism, concept is developing with the deepening and broadening of human being's mind. The developing process of syndrome concept in traditional Chinese medicine also takes the same way. In the Sui and Tang Dynasties, the connotation of syndrome concept was defined and the embryonic form of syndrome differentiation of zang-fu viscera was formed. In the Song, Jin and Yuan Dynasties, the development of syndrome concept embodied in optimizing the theoretical research based on clinical practice and experiences according to many medical masters in different denominations. The syndrome differentiation of eight principles was established to standardize and perfect the principles of syndrome differentiation in the Qing Dynasty. Modern research of syndrome concept is manifested in objectifying the process of research of syndrome and diseases in different levels and aspects by use of advanced scientific technology.

Alzheimer's disease (AD) is a progressive, degenerative disease of the brain, which causes learning and memory to become seriously impaired. AD not only influences the patient's quality of life, but also places a great burden on caregivers. With the increasing of aging population, the pressures can be wide-ranging, involving social, psychological, physical, and economic elements of the caregivers' life.The cause and progression of Alzheimer's disease are not well understood. Currently used treatments include pharmaceutical and psychosocial ones, each offering a small symptomatic benefit. Actually, there are still no available medicines and treatments to delay the progression of the disease. Therefore, the development of a new ideal medicine to treat AD patients becomes the first priority. In recent years, most researchers have turned to natural products, hoping to find a drug candidate to cure AD patient. Baicalein, a traditional Chinese medicine extracted from Scutellaria Baicalensis (Chinese herb), has been demonstrated holding the properties of anti-inflammatory, anti-apoptosis, anti-oxidant, and improving learning and memory of human brain. Baicalein is becoming a potential ideal medicine for treating AD patient.

Objective To observe the therapeutical effect of posterior vertebral column resection on chronic thoracolumbar tuberculosis with secondary paraplegia and to provide a safe and effective method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.MethodsFrom Aug.2007 to Mar.2010,12 cases with chronic thoracolumbar tuberculosis and secondary paraplegia were surgically treated by posterior vertebral column resection and Titanium net support for bone graft and internal fixation operation treatment.Cobb angle was measured,and conditions of internal fixation were observed before and after the operation by X-ray films.Neurological status were evaluated by Frankel grades.ResultsThe follow-up periods was 6- 18 months( on average 11 months).Operations eased all patients' back and chest pain.Frankel grade increased from C preoperatively to grade D or E postoperatively in 6 cases,from grade D to E in 4 cases and from grade B to C in 1 case.No obvious improvement of Frankel grade was observed in the other patient of grade B.The average Cobb angles were(76.0 ± 23.4) ° before surgery,( 15.5 ± 6.3 ) ° at one week after surgery and ( 16.0 ± 8.2) °at the last follow-up.The difference in the Cobb angle before and at one week after treatment was significant( t =3.41,P ＜ 0.01 ).No difference was found in the Cobb angle between at one week after treatment and at the last follow-up (t =1.58,P ＞ 0.05 ).All patients got bony fusion with Titanium net.No complications occurred with internal fixation.Conclusion Posterior vertebral column resection is a feasible method for the treatment of chronic thoracolumbar tuberculosis with secondary paraplegia.It achieves neurological decompression with high correction rate and minor injury,and no anterior surgery is needed.

To investigate effects of cultured astrocytes from Sprague Dawley rat cerebral cortex on the development of PC12 cellsderived from rat pheochromocytoma, PC12 cells were cocultured with astrocyte according to different astrocytes/neurons ratio(50:1～1:1) , or with serum-free conditioned medium of astrocytes(ACM). The vitality of PC12 cells was measured by sensi-tive MTT method and their morphologic features were observed by Olympus light microscope. The results showed: (1) WhenPC12 cells were cultured with ACM, compared with the control group, the vitality of PC12 cells was increased significantly (0.255+0. 012 vs 0. 510±0. 036, P<0. 001) and the morphological changes were not obvious in the experimental group. (2) WhenPC12 cells were cocultured with astrocyte in the ratio of 30: 1～1: 1, not only was the vitality of PC12 cells enhanced, but alsothe neurite-outgrowth of PC12 was observed. (3) When PC12 cells were cocuhured with astrocyte in proportion of 50: 10～40 : 1, the vitality of PC12 cells was also enhanced, but the neurite-outgrowth of PC12 was not found. This study suggested en-hancement of PC12 cell-vitality was mediated by soluble factors produced by astrocytes, while activity of the neurite-promotingwas associated with cell-cell contact and with the ratio of two cells.

OBJECTIVE: To observe the effects of Huatan Xiezhuo Recipe (HTXZR) on fatty liver of rats. METHODS: Forty-eight SD rats were randomly divided into five groups: normal control group, untreated group, Dongbao Gantai Tablet (DBGTT)-treated group, low-dose HTXZR-treated group and high-dose HTXZR-treated group. Fatty liver was induced in the rats by hyperlipid diet and intraperitoneal injection of tetracycline. The pathological changes of liver tissues in rats were observed, and the liver function, serum leptin, insulin resistance index, triglyceride (TG) and free fatty acid (FFA) in the liver were detected. RESULTS: The levels of serum leptin, insulin resistance index, FFA and TG in rats of the three treated groups were lower than those of the untreated group (P<0.01), and such effects in the HTXZR-treated groups were more significant than those in the DBGTT-treated group (P<0.05). CONCLUSION: The main action mechanisms of HTXZR in treating fatty liver are probably to promote the lipid metabolism, decrease the leptin and insulin resistance.
