Objective To investigate whether high cholesterol diet (HCD) can cause gallbladder cholesterol calculus and to probe into the mechanism of its influence on gallbladder motility function. Methods Noumenon dissect and B-type ultrasonic apparatus was used to observe condition of gallbladder calculus formation in HCD group and normal control group; gallbladder motility function of the two groups were measured; radioimmunoassay was used to measure plasma CCK level in fast and 30min after fatty meal; colorimetry was used to measure cholesterol concentration in bile; and the pathologic changes of gallbladder specimen were observed. Results The gallbladder cholesterol calculus formation rate and cholesterol concentration in bile of HCD group was remarkably higher than that in normal control group (P

AIM　to compare the bioavailability and pharmacokinetics of two acyclovir tablets. METHODS　Concentrations of acyclovir in 10 men serum after po 600 mg of two acyclovir tablets were determined , in random 2-way crossover design. Pharmacokinetic parameters were also estimated. RESULTS　The peak concentrations of test and reference tablets were 1.24±0.49 and 1.17±0.20 μg/ml, the AUC 7.56±1.80 and 7.56±2.10μg*h/ml, respectively. The relative bioavailability was 101.36%±11.62%. The test formulation was found bioequivalent to the reference in AUC and Cmax by two one-side t test. CONCLUSION　Two tablets were bioequivalent.

Objective To investigate the effect of Naoxintong capsule on clinical efficacy and inflammatory factors in patients with ischemic stroke.Methods 81 patients with ischemic stroke were divided into two groups according to random number table method.40 patients in the control group were treated with treatment guidelines,and the observation group was treated with another Naoxintong capsule.The serum interleukin-10(IL-10),tumor necrosis factor-a(TNF-α),high sensitivity C reactive protein (hs-CRP) level,National Institutes of Health Stroke Scale (NIHSS) and clinical efficacy of two groups were compared.Results After treatment,the hs-CRP,TNF-α levels of the observation group were (12.36 ± 3.09) mg/L,(129.62 ± 29.27) mg/L,which were lower than those of the control group[(1 6.71 ± 4.29) mg/L,(186.52 ± 37.62) ng/L,t =8.189,5.287,all P ＜ 0.05).After treatment for 7d and 30d,the NIHSS scores of the observation group were (14.28 ± 3.24) points,(5.23 ± 1.47) points,which were lower than those of the control group[(18.76 ±4.53)points,(8.16 ±2.42)points,t =14.689,12.827,all P ＜0.05].IL-10 level of the observation group was (49.82 ± 6.59) pg/mL,which was higher than (42.57 ± 9.82) pg/mL of the control group (t =6.759,P ＜ 0.05).The total effective rate of the observation group was 92.68％,which was higher than 77.50％ of the control group (x2 =4.897,P ＜ 0.05).Conclusion Naoxintong capsule has significant therapeutic effect on ischemic stroke,can effectively improve the inflammatory reaction after cerebral infarction,promote the recovery of neurological function and it is worthy of promotion.

Nowadays,more and more basic and clinical researches on absorbable internal fixators are car- fled out in China.This paper reviews the recent researches on biodegradation,absorption,and mechanical prop- erties of absorbable internal fixators,their effects on bone mineral density and structure and injury of epiphyseal plate,and their clinical applications.Some problems that have not been solved and future research key points are highlighted and discussed.

Objective To investigate the effect and psychological intervention of the treatment of hemodialysis internal fistula with Hirudoid combined with far infrared ray. Methods 80 cases of hemodialysis fistula were diagnosed and treated from January 2014 to December 2016 in Lishui Central Hospital,according to different treatment intervention methods, which were divided into two groups, each group with 40 cases. The control group was treated with routine nursing and far infrared therapy, and the observation group was treated withpsychological intervention and Hirudoid+far infrared therapy. The clinical efficacy, the improvement of clinical symptoms and the incidence of complications were compared between the 2 groups. Results The clinical effect of the observation group was better than that of the control group, the improvement of the clinical symptoms was better than that of the control group,the complication rate was lower than the control group,the difference was statistically significant (P<0.05). Conclusion The clinical effect of psychological intervention plus Hirudoid+far infrared ray in the treatment of hemodialysis fistula patients is significant,which can effectively improve the clinical symptoms and complications in patients with less, and is worthy of clinical application.

Objective To explore the regulatory effect of Nervilia fordii Injection ( NFI ) on inflammatory cytokines in rats with lipopolysaccharide ( LPS) -induced acute lung injury ( ALI) , and to explore its possible interfering mechanism . Methods The rats were randomly divided into normal group , model group , Shenmai Injection group, and NFI group. J774 macrophages were stimulated by LPS to establish the cell model in vitro, and in vivo ALI rat model was established by injection of LPS through the sublingual veins. Electronic microscope and enzyme-linked immunosorbent assay (ELISA) were used for observing the proliferation of J774 macrophages, the levels of supernatant inflammatory cytokines secreted by J774 cells, and the levels of serum inflammatory cytokines . Results The proliferation of LPS-induced J774 macrophages was increased , and the secretion of inflammatory cytokines was disordered. Uncontrolled inflammatory reaction occurred in the lung after the rats were administrated with intravenous injection of LPS . Both NFI and Shenmai Injection could inhibit the proliferation of J774 macrophages. NFI could also significantly inhibit the levels of supernatant and serum tumor necrosis factor (TNF) -α and interleukin 6 (IL-6) expression (P<0.05 or P<0.01), and it could increase the level of supernatant IL-10 (P<0.01) and decrease the level of serum interleukin 10 (IL-10) in rats (P<0.05), but couldn’t regulate the secretion of monocyte chemoattractant protein 1 (MCP-1) (P>0.05). Conclusion NFI has better preventive and therapeutic effect for ALI than Shenmai Injection, and its possible mechanism is related with the inflammatory regulation and lung injury relief through the suppression of excessive expression of TNF-α and IL-6 .

Objective To establish a method of large-scale cryopreservation of porcine hepatocytes to meet the need of the biological artificial liver. Methods Porcine hepatocytes were isolated from Chinese miniature swines by collagenase disgestion. The cells were suspended in self-made nutrient solution supplemented with 10% DMSO. The hepatocytes (1?10 10~2?10 10) were stored in liquid nitrogen (-196℃) after being treated with two kinds of freezing methods. The cryopreserved hepatocytes were thawed in 39℃ water after one month and cultured. The morphology, viability and the function of thawed hepatocytes were observed. Results The cell viability of cryobreserved hepatocytes after both freezing methods were high. However, synthesis of urea nitrogen and glucose was higher in stepwise temperature lowering group compared with programmed temperature lowering group. Conclusion The results indicate that the cryopreservation method is feasible and simple, large amount porcine hepatocytes can be cryopreserved.
