Objective To observe the clinical curative effect of Huoxue-Zhitong decoction combined with mannitol in the treatment of swelling and pain after operation of tibiofibular fracture. Methods 86 patients with swelling after the operation of fracture of tibia and fibula were randomly divided into two groups, with 43 cases in each group. The observation group was treated with intravenous rapid infusion of mannitol, the control group was treated with Huoxue-Zhitong decoction combined with intravenous rapid infusion of mannitol. Swelling, pain visual analogue scale (VAS) score of limb of patients at 1 D and 10 d after operation, time of detumescence and acesodyne and the total efficiency of the treatment between the two groups were compared. Results The indices of the two groups mentioned above at 7 d after the operation significantly decreased, the value in the observation group was lower than the control group (1.3 ± 0.7 cm vs. 1.9 ± 0.9 cm, t=3.451; 1.5 ± 0.6 points vs. 1.9 ± 0.7 points, t=2.845; all P<0.01); The detumescence and acesodyne time of the observation group was shorter than those of the control group (8.6 ± 1.7 d vs. 9.8 ± 2.3 d, t=2.751; 5.5 ± 1.4 d vs. 6.7 ± 1.7 d, t=3.573; all P<0.01), the total efficiency in the observation group was superior to the control group, there were statistically significant differences (97.7% vs. 83.7%; χ2=4.961, P=0.026). Conclusions Huoxue-Zhitong decoction combined with mannitol is effective and safe in the treatment of swelling and pain after operation of tibiofibular fracture.

Objective To explore the inhibition effect and the possible mechanism of resveratrol on human hepatocellular carcinoma cell line Bel-7402 both in vitro and vivo.Methods Four Res drugs in the experiment group,the final concentrations were 12.5,25,50,100μmol/L,the control group at the same time set not containing Res drugs,MTT assay was used to measure the inhibition of resveratrol on Bel-7402.The expression of Bcl-2 was detected by RT-PCR and Western Blot.The levels of IL-2,IL-6,IL-12 and TNF-αwere detected by ELISA.Results Resveratrol inhibited Bel-7402 cell proliferation in dose and time manner,and influenced the expression of Bcl-2 mRNA and protein.At the same time,resveratrol inhibited the growth of tumor and improved the levels of IL-2,IL-6,IL-12 and TNF-α.Conclusion Resveratrol could inhibit Bel-7402 cell proliferation both in vitro and vivo, the possible mechanism may be that resveratrol could low down the expression of Bcl-2 and improve the levels of IL-2,IL-6,IL-12 and TNF-α.

Objective To observe the effects oftelmisartan (TEL) on learning and memory functions of animal models of Alzheimer's disease combined with hypertension.Methods Seventy male spontaneously hypertensive rats were randomly assigned into 7 groups:control group,sham-operated group,model group,low TEL group (1 mg/[kg· d]),high TEL group (10 mg/[kg· d]),low TEL+GW9662 group (Tel 1 mg/[kg·d]+GW 1 mg/[kg·d]),and high TEL+GW9662 group (Tel 10 mg/[kg·d],GW 10 mg/[kg·d],n=10);the lateral cerebral ventricle of rats in the later 5 groups were injected with beta-amyloid peptide 1-42 (Aβ1-42);rats in the sham-operated group were given the same volume of normal saline,and those in the control group did not give any treatment.The learning and memory abilities of these rats were detected by Morris Maze test;microglia level and casepase-3 expression were assessed by immunohistochemical stainning.Results Constant-bearing navigation indicated that as compared with the model group,the high TEL+GW9662 group,control group and sham-operated group had significantly shorten escape latency on the 3rd d of experiment (P＜0.05),and as compared with the model group,the low TEL group,high TEL group and high TEL+GW9662 group had significantly shorten latency (P＜0.05).Spatial probe test showed that the times of crossing the platform,target quadrant residence time in the low TEL group,high TEL group and high TEL+GW9662 group were significantly larger/longer than those in the model group (P＜0.05).The casepase-3 expression and microglia level in the CA1 area of model group were significantly higher than those in the control group (P＜0.05);The Ibal and caspase-3 expressions in the low TEL group,high TEL group and high TEL+GW9662 group were significantly weaker than those in the model group (P＜0.05).Conclusion TEL has preventive effect on cognitive decline in rat models of Alzheimer's disease complicated with hypertension,and can be restrained by GW9662,which suggests that these benefits might be partly resulted from PPAR-γ activation and intracranial infection inhibitation.
