Objective:To observe the effect of prolonging life and inhibiting tumor growth of Xiaozhensan on H22 cells-bearing mice and study the mechanism of action. Methods:①H22 cells-bearing mice models were made by subcutaneous injection and were divided into six groups:model group,low,middle and high dosage groups of Xiaozhensan,5-FU group,5-FU plus Xiaozhensan middle dosage group. After 10 days' treatment,the mice were killed and the anti-tumor rates were calculated,to detect the content of IL-2 and observe pathological sections of tumor and expression of Bcl-2 by immunohistochemical method. ②H22 cells-bearing ascites mice models were divided as the above. The living days of the mice were recorded,the prolongation of life span were calculated. Results:Xiaozhensan had the function of inhibiting the growth of tumor,and there was the dependability between quantity and effect. In pathomorphology,the sections of Xiaozhensan groups showed nuclear shrinkage,necrosis,hemorrhage,inflammatory cell infiltration on the periphery,etc. Xiaozhensan could increase the content of IL-2 and inhibit the expression of Bcl-2. Xiaozhensan combined with 5-FU can prolong the life span of the mice bearing ascites tumor. Conclusion:Xiaozhensan had the function of inhibiting the growth of tumor. The mechanism of action may be concerned with these aspects:enhancing the cellullar immunologic response and strengthening the ability to resist tumor,inducing apoptosis and weakening reproductive activity of tumor,etc. Middle dosage group of Xiao Zhen San combined with anticarcinogenic western medicin can prolong the life span of the mice bearing ascites tumor. This study provided dependable experimental documents for clinical application of Xiaozhensan,and had some guiding significance in clinic.

[Objective]This paper mainly introduced Professor YE Jin 's experience in treating girls with precocious puberty from liver syndrome differentiation and characteristics of prescription medication.[Methods] On account of three main symptoms of girls with precocious puberty at first visit, including thelarche, leukorrhea and menses, we explore the relation between liver and the causes of this disease from the viscera-state doctrine as well as the meridian theory. Then introduce Professor YE Jin's methods and empirical medication in treating girls with precocious puberty based on liver. In order to analyse her experience, a clinical case was reported. [Results]Professor YE holds that the pathogenesis of girl 's precociouss puberty closely related to liver. The deficiency of liver-yin and kidney-yin is the basic pathogenesis of precocious puberty, which is often accompanied with liver qi depression or even liver qi depression transforming into fire. On the basis of nourishing yin and purging fire, Professor YE emphasizes treating precocious puberty from liver. In practical terms, flexibly applying the ideas of softening, soothing and clearing liver can effectively improve the clinical symptoms. She makes the selection and compatibility of Chinese medicine comforming to the characteristics of children 's physiology and pathology and values the protection of vital energy. The reported case specifically demonstrates treating a girl 's thelarche from liver syndrome differentiation as well as the empiric therapy. [Conclusion]Professor YE Jin's experience in treating girls with precocious puberty is well worth learning for its significant curative effect.

Objective To determine the effects of down-regulating serine/threonine/tyrosine kinase 1 (STYK1) on the proliferation,apoptosis and invasion and on MEK/ERK and PI3K/AKT signaling pathways in human colorectal cancer cell line HCT-15.Methods The expression of STYK1 protein was downregulated by RNA interference technique in HCT-15 cells.Then,the STYK1 protein expression was detected by Western blotting.CCK-8 assay was used to measure the effect of STYK1 down-regulation on the proliferation of the cells,flow cytometry was employed to detect the cell apoptosis,and Transwell chamber assay was adopted for cell invasion ability.The expression levels of p-ERK1/2 and p-AKT were detected by Western blotting.Results Compared with the siRNA NC group,STYK1 down-regulation significantly inhibited the proliferation (P ＜ 0.01) and invasion (P ＜ 0.01),induced cell apoptosis (P ＜ 0.01),and suppressed the expression levels of p-ERK1/2 and p-AKT in the HCT cells transfected with STYK1 siRNA (P ＜0.01).Conclusion STYK1 down-regulation inhibits the proliferation and invasion and induces the apoptosis in colorectal cancer cells,which may be related to its inhibition on the MEK/ERK and PI3K/AKT signaling pathways.

OBJECTIVE:To observe the protective effect of the traditional Chinese medicine Yiqimingmu oral solution on photochemical damage of retina in rats. METHODS:SD rats were divided into four groups randomly:negative control group, model group, low dose Yiqimingmu oral solution group and high dose Yiqimingmu oral solution group. All the groups except the control one were continually exposed to Lux (1 900?106.9) green fluorescent light for 24 hours to establish retinal photochemical damage model. The low dose and high dose groups were administered intragastrically with Yiqimingmu oral solution (15mL?kg-1?d-1 and 30mL?kg-1?d-1) 7 days before light expose. Normal saline solution was administered intragastrically in control and model group. At 6 hours and 6, 14 days after light expose, the content of malandialdehyde (MDA) and activity of SOD in rats' retina were measured. The histopathologic changes were observed by transmission electron microscopy and light microscopy. RESULTS:At 6 and 14 days after light expose, the activity of SOD in Yiqimingmu solution high dose group were higher than in the model control group(P

Objective To observe the results of function MRI and perimetry in patients with visual pathway diseases. Methods Three patients (6 eyes) with pituitary adenoma and craniopharyngioma diagnosed via pathological examination and three healthy volunteers aged from 24 to 30 were collected. The best corrected visual acuity was non-light perception-1. 0 in the 6 sick eyes and 1. 0 in the healthy eyes;all the involved individuals had no other ocular diseases except myopia and without any contraindications of MRI. Common tests including the best visual acuity, fundus test by direct or indirect ophthalmoscope, center static visual field tested by Octopus 101 perimeter, program 32, tendency oriented perimetry were performed. The visual stimulation subtended a field of view of about 12 degrees,consisted of high contrast and drifting checkerboards. MRI parameters: GE signa VH/i 3. 0T scanner. Functional data: GRE-EPI sequence, 20 slices lying perpendicular to the calcarine sulcus. Anatomical data was obtained using 3DSPGR sequence to acquire high resolution. The cortical surface was unfolded and then cut and inflated. Functional data was presented to the inflated surface and subsequently analyzed by AFNI software. Results In six eyes, three had temporal defects, two had upper temporal visual field defects, and the other one did not finish the visual field test. The retinotopic representations of health adults were obtained by using the phase-encoded visual stimulation. The Eccentricity coordinate maps showed that foveal representations lay in the occipital poles and the representations appeared further anterior as eccentricity increased. The polar angle coordinate maps showed that early retinotopically organized areas had a representation of visual field. The visual cortex beneath the calcarine sulcus matched with the upper visual field of the opposite side and which upon the calcarine sulcus matched with the under visual field of the opposite side. Less or no visual cortex response was revealed in the patients' function MRI or the response in injury side was vanished. The visual cortex response related with the visual field defects could not be induced in function MRI. Conclusion There is a good correlation between function MRI data and the results of perimetric evaluation. The function MRI can show the visual cortex response correlated with the visual field defects of the patients with visual pathway diseases.
