Objective To establish the disease-syndrome integrated animal models suitable for the studies of TCM through differen- tiating the property of TCM syndromes of spontaneous diseased animal models.Methods With the observation on general behaviors, irritable degree,turning endurance time,pain threshold,urine and stools,luster of hair,growing speed of hair,body weight,tongue condition,degree of eyeball protruding,conjunctiva chroma,blood pressure,heart rate,etc.of spontaneous hypertension rats(SHR) and the comparison with normal rats,the study was carried out on the macroscopic description of property of TCM syndrome of SHR (14~18 weeks of age)and their ethology.Results The blood pressure of SHR at the early stage tended to raise with age growing. Compared with the normal group,the heart rate of SHR rats was obviously quicker(P

Objective:To learn the effect of personality in the course of cognitive decline.Methods:106 aged people from two districts were selected randomly.Arithmetic,digit span,picture filling,block patterns,digit symbol,visual attention span,spatial reasoning were used to learn the cognitive ability,“Kartaier's 16 personality factors test”were used to explore the personality of aged people.Results:16 personality factors test shows that old people are more deferential and self-assured.The relation between reasoning and arithmetic,rule-consciousness and arithmetic,abstractedness and digit span,reasoning and block design,dominance and digit symbol,sensitivity and special reasoning,apprehension and visual attention span,openness to change and visual attention span reach the statistical significance.Conclusion:Age is the most important reason to the cognitive impairment in aged people, education can prevent the cognitive impairment in a large degree.Personality can affect the cognitive ability although different personality factor affect different cognitive fields.

Objective: To investigate the antihypertensive time-effect and dose-effect features of Sancao jiangya decoction(SCD).Methods: The blood pressure of spontaneously hypertensive rats at different time points were measured after treatment with Sancao jiangya decoction of low,middle,high concentration by tailartery blood pressure measurement for conscious rats.Results: The blood pressure was decreased at 2 hours after drug taken,there were significant dose-effect relationship between the antihypertensive effect and the low,middle,high dose.At 4h after drug taken,the high,middle dose had dose-effect correlation,but the low-dose had no antihypertensive effect.Further research on the middledose shows that the blood pressure reduced at 1h after drug taken,and the stable antihypertensive effect was keeping during 1-4h,the blood pressure began to rise at 6h,and got back to the level before drug taken at 8h.Conclusion: To choose the Middle-dose(10.4g crude drug/kg body weight) and 2h after drug taken is appropriate for SCD's use.This result laid a substantial foundation for further research on effects evaluation and mechanism of antihypertensive medicine.

Compatibility mechanism study of Chinese herbal compound (CHC) has been one of key contents in Chinese medical research, but the present research methods are not suitable for its own features due to its complexity, which has restricted the process of modernization and intemationalization of Chinese medicine. In this paper, we addressed that the compatibility is closely correlated to their in vivo metabolic processes. The preparation of active small molecules monoclonal antibodies in herbs and testing a variety of effective compositions simultaneously using immunoassay can clarify the in vivo metabolism and mutual interactions of Chinese herbs, which is a new thought of studying the compound compatibility mechanisms.

OBJECTIVE To explore the expression of long non-coding RNA (LncRNA) HOTAIR, enhancer of Zeste homolog 2 (EZH2) and vascular endothelial growth factor (VEGF) in nasopharyngeal carcinoma (NPC) and their relationship between HOTAIR and prognosis. METHODS We examined the expression of HOTAIR, EZH2 and VEGF in NPC tissues, and analyzed the clinical significance of HOTAIR expression in patients with NPC. RESULTS We found that the expression of HOTAIR, EZH2 and VEGF in the NPC tissues were significantly higher than those in the chronic nasopharyngitis tissues in the gene and protein levels (U=955,P<0.05). The HOTAIR was positively correlated with VEGF (r=0.599,P<0.001), VEGF was positively correlated with EZH2 (r=0.369, P=0.012), and HOTAIR had no significant correlation with EZH2 (r=0.139,P=0.357). Moreover, HOTAIR expression levels increased with clinical stage progression. CONCLUSION The expression of HOTAIR, EZH2 and VEGF were significantly increased in the NPC tissues, and the expression of HOTAIR was related with the TNM stage, the clinical stage and the short term therapeutic effect of the NPC patients, which indicated that the HOTAIR might be used as a biological indicator to determine the prognosis of the NPC.

Oxidation method with sodium iodide was used to synthesize immunogenic antigen (PF-BSA) and coating antigen (PF-OVA) of paeoniflorin. UV spectroscopy showed that paeoniflorin was successfully conjugated with BSA and OVA. After immunized by PF-BSA, the mice can produce anti-paeoniflorin antibodies specifically. The ELISA test results showed the high titer (1:12 800) and specificity (IC50 = 0.791 mg x L(-1)) of the antiserum from mice injected with PF-BSA. Also, the antiserum showed low cross activities against nine traditional Chinese medicine (TCM) of small molecules. These artificial antigens were successfully synthesized and the anti-paeoniflorin antibody well prepared, which provides the experimental basis for the further study of ELISA and its kit.

Objective To evaluate the utility of multi-slice computed tomography (MSCT) in assessing acute non-reperfused myocardial infarct size. Methods Seven domestic pigs (mean weight 17.3 ± 1.9 kg) underwent ligation of the distal left anterior descending artery to establish a model of acute myocardial infarction (MI). MSCT and triphenyltetrazolium chloride (TTC) staining were performed two hours later. The following data were acquired and analyzed:MI volume (%), CT values of the infarcted region, left ventricular cavity and normal cardiac tissue at various scanning time-points (1, 5, 10, 15, 20 min after contrast injection). Results Using MSCT, the overall MI volume showed a time-dependent decrease, with a reduction of 28.87%after 20 min. The greatest reduction occurred at the 5 min time-point. In TTC staining, MI volume was 9.87%± 2.44%. When MI size, as determined by MSCT, was compared with that by TTC staining in Bland-Altman plots, there was a better agreement at 5, 10, and 15 min time-points at 1 and 20 min. Conclusions The study indicates that double-phase scanning examination using MSCT is a useful tool to assess MI size, and the optimal late-phase scanning time-point set within 5-15 min of contrast injection.

Objective To assess the treatment effects of As_2O_3-PLGA microspheres on VX2 rabbits liver tumor models.Methods Thirty-two New Zealand white rabbits were involved with formation of VX2 rabbits liver tumor models,and randomly divided into 4 groups of 8 each.(a)As_2O_3 plus 0.9% NaCl solution group:3 F co-catheter was plugged into hepatic artery,and then As_2O_3(3 mg/kg)plus 10 ml 0.9%NaCl solution was injected into the tumor through the feeding artery;(b)As_2O_3-PLGA microspheres group :As_2O_3- PLGA microspheres(3 mg/kg)was injected into the tumor through the feeding artery;(c)PLGA mierospheres group:Injection of PLGA microspheres(3 mg/kg)injected into the tumor through the feeding artery;(d) control group:0.9% NaCl solution(10 ml)was injected into the feeding artery.Dual phase helical CT scans were performed the day before treatment,20 days after treatment and finally the rabbits were sacrificed.The sizes of the tumor were measured and followed by histopathological analysis and HE staining.Results The volumes of tumors post operatively of group a,b,c and d were(31.08?11.15)cm~3,(3.82?2.537)cm~3, (13.22?4.665)cm~3 and(115.8?62.01)cm~3 respectively.The most significant treatment effect was available in group b,with more coagulation necrosis and fibrotic tissue formation.Statistical analysis indicated that the treatment effects of group a,b,c were better than that of group d with significant difference which can be also seen between group a and b,group b and c.Conclusion As_2O_3-PLGA microspheres shows rather excellent chemoembolization effects on VX2 rabbit liver tumor model with safely.
