Objective: To evaluate the feasibility of taste-masking by electronic (E)-tongue and provide a reference for the drug taste-masking study. Methods: Andrographis Herba was used as the carrier of bitter Chinese materia medica (CMM), sodium acetate (NaAc), sodium cyclamate (SC), adenosine-5′-monophosphatedisodiumalt (AMP), and 2, 4-dihydroxyhenzoic acid (DA) as the taste-masking agents. The data obtained by the E-tongue were analyzed through principal component analysis (PCA), and Euclidean distance in the data space of different dimensions was calculated. Regarding the distance of bitterness (D) as the evaluation index, then whether the data analyzed by the E-tongue and volunteers were the same or were not investigated. Results: The evaluation results of the taste-masking agents by E-tongue were similar to the taste by volunteers except NaAc, suggesting that some conditions should be required to evaluate the effect of CMM taste-masking. Conclusion: This study shows that E-tongue could be used for evaluating the effect of CMM taste-masking under certain conditions. To evaluate the gustation information by E-tongue, we should use the professional knowledge of pharmacy, chemical and other related disciplines to analyze and improve this evaluation method and model gradually.

Objective To study the efficacy of external dissection & internal ligation for beating mixed hemorrhoids, and compare with Milligan-Morgan. Methods One hundred and twenty-six patients with mixed hemorrhoids were divided into two groups: treatment group(66 cases)and controlled group(60cases).In treatment group used external dissection & internal ligation for treating mixed hemorrhoids, but in eontrolled group used Milligan-Morgan. Then the differences between both groups in healing time of wound surface, as well in the statuses of bleeding, pain, edema, anus stenosis, and anus overflow liquid were observed. Results Averaged healing time in treatment group was significantly shorter than that in controlled group, (8.2±2.6)days vs (17.4±3.8)days, P＜0.01.The anus stenosis and anus overflow liquid were significantly less in treatment group than those in controlled group, P＜0.01.Conclusion External dissection & internal ligation of hemorrhoids for treating mixed hemorrhoids decreases anal transitional zone(ATZ)disorganization, shorten healing time, and significantly decreases crissum scar,protectes anus function effectively.

Objective To investigate the effect of different immunosuppresants on CAN by affecting TGF-?_ 1 and Smads signal pathway. Methods The SD→Wistar rat accelerated kidney sclerosis model was made following the procedure of Kamada with our modification. The rats were divided into 6 groups (each group n=8): Group A, psudo-OP group; Group B, control group; Group C, CsA 6 mg?kg~ -1?d~ -1; Group D, FK506 0.15 mg?kg~ -1?d~ -1; Group E, MMF 20 mg?kg~ -1?d~ -1; Group F, RPM 0.8 mg?kg~ -1?d~ -1. After 4, 8, 12 weeks, the animals were killed. The immunohistochemistry and real-time fluorescence quantitative PCR were used to detect localization and expression of TGF-?_ 1, Smad2 and smad7 in transplant kidney. Results CsA and FK506 simultaneously stimulated the gene expression and protein production of TGF-?_ 1 and Smad2 and inhibited the expression of Smad7 in transplant kidney, whereas MMF and RPM could down-regulate the gene expression and protein production of TGF-?_ 1 and smad2 and up-regulate the expression of smad7. There was no significant difference between CsA group and FK506 group, as well as MMF group and RPM group.Conclusion Different immunosuppresants can affect TGF-?_ 1 and Smads signal pathway in kidney graft. CsA and FK506 can cause CAN, owning to up-regulate the expression of Smad2, and down-regulate the Smad7 expression. MMF and RPM can prevent the progression of CAN because of down-regulating the expression of Smad2 and increasing Smad7 production.

Objective To investigate the preventive and therapeutic effectiveness of Yisheng herbal injection against chronic allograft nephropathy in rats.Methods Renal transplantation was performed from SD to Wistar closed colony strain rats. Before the transplantation, the kidney was preserved in 0- 40 ℃ heparin sodium chloride solution for one h. The rats were divided into 4 groups: Group A only received CsA 10 mg/kg every day; Groups B, C and D received low dose of Yisheng+CsA, high dose of Yisheng+CsA and CsA+MMF, respectively. Blood creatinine, pathological changes of the renal grafts and the expression of transforming growth factor ?1 in transplanted renal tissues were observed 4, 8 and 12 weeks after operation.Results After the transplantation, the serum creatinine level in group A was significantly higher than in groups B, C and D ( P

? Choroidal neovascularization is the primary pathogenesis of neovascularage - related macular degeneration ( nAMD ) , and the role of vascular endothelial growth factor ( VEGF ) in neovascularization has been widely recognized. Currently, drugs target different targets of VEGF have been widely used in the treatment of nAMD. As a subtype of VEGF, placental growth factor ( PlGF) has synergistic effects with VEGF-A on promoting angiogenesis, stimulating the migration of endothelial cell proliferation and mediating immune inflammatory response. There is no expression of PlGF in mature blood vessels so PlGF hashigh specificity. ln this paper, the role of PlGF in the pathogenesis and treatment of nAMD is reviewed.

Objective To observe the hemodynamic effects of open-loop target controlled infusion (OLTCI) and closed-loop target controlled infusion (CLTCI) of propofol and fentanyl for general anesthesia induction. Methods Twenty-four female patients with ASA grade I-II who were performed thyroidectomy were randomly allocated into two groups: OLTCI group and CLTCI group(n=12). In OLTCI group, anesthesia induction and maintenance were performed with propofol and fentanyl at the target concentrations of 3 ?g/mL and 3 ng/mL, respectively. In CLTCI group, double CLTCI were performed. Titrations of propofol and fentanyl were guided with bispectral index (BIS) and product of systolic pressure and heart rate (HR). Initiative concentrations of this closed-loop system were 3 ?g/mL and 3 ng/mL, step-up or step-down concentrations were 0.5 ?g/mL and 0.5 ng/mL, and the highest concentrations were 6 ?g/mL and 5 ng/mL, respectively. HR, mean arterial pressure (MAP), HR variability, BIS value and the dosages of propofol and fentanyl in various time of the two groups were recorded. Results One min after intubation and simulative incision stimulation, BIS value of both groups were increased, but the BIS value in CLTCI group was less increased than OLTCI group(P

This study is to investigate the effects of ceramide on GSTA1 expression in Caco-2 cells. After being exposed to ceramide for a fixed time, GSTA1 protein expression was detected by Western blotting analysis; GSTA1 mRNA expression was detected by real time PCR; dual luciferase assay was used to analyze GSTA1 transcriptional activity and GSTA1 activity was determined toward androstanedione (AD) as substrate. The data showed that ceramide can significantly induce the expression of protein and GSTA1 mRNA, and increase transcriptional activity and enzyme activity of GSTA1. The results demonstrated that ceramide may increase resistance to chemotherapeutics in Caco-2 cells by up-regulating the expression of GSTA1.

0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.
