1.The relationship between AIF and apoptosis and the research of treatment of colorectal cancer related to AIF
International Journal of Surgery 2010;37(11):753-756
Numerous pro-apoptotic signal transducing molecules act on mitochondria and provoke the permeabilization of the outer mitochondrial membrane, thereby triggering the release of pro-apoptotic proteins potentially.One of them is much important,which called apoptosis inducing factor(AIF).Upon lethal signaling,AIF released from mitochondria, which translocates, via the cytosol to the nucleus, where it binds to DNA and provokes Caspase-independent chromatin condensation and leading to apoptosis.It has been found gradually that AIF has impotant effect in some malignant cancer cells(such as colorectal carcinoma cell), especially its regulation effect in cell death.Recently some of researches indicate that inducing cell apoptosis by effecting on the releasing or expressing of AIF, has been a new research direction of colorectal carcinoma therapy.

Objective:To establish a DSC method for the determination of mannityl nicotinate. Methods:Indium was used to cor-rect the instrument including temperature correction and heat flow correction. The atmosphere was nitrogen and the flow rate was 20 ml ·min-1 . The sample volume was 1-3. 5 mg with precision reached to 0. 01mg. The initial temperature was 30 ℃, raised to 120 ℃ at the rate of 10℃·min-1 , maintaining for 1 min at 120℃, and raised to 280℃ at the rate of 2. 5℃·min-1 . The results of DSC and HPLC were compared. Results:Mannityl nicotinate had a good linear relationship between the heat absorption and the amount of sam-ple within the range of 1. 05-3. 44 mg (r=0. 9990). The average recovery was 98. 86% (RSD=1. 59%,n=9). The content of nia-cin detected by HPLC and DSC was 97. 77% and 97. 80%, respectively, and the relative mean deviation of the two values was 0. 015%. Conclusion:The DSC method is accurate and rapid, and can be used for the determination of mannityl nicotinate like HPLC.

OBJECTIVETo explore the effects of sacral canal injection on nerve root local inflammatory factors in rat model with lumbar disc herniation, in order to identify its mechanism of treatment.
METHODSForty-eight male SD rats were randomly divided into sham operation group(group A), model group (group B), Chinese medicine group(group C) and western medicine group(group D). There were 12 rats in each group. The model of lumbar disc herniation was established using compression and inflammatory stimulation in group B, C, D. All rats were given epidural catheterization and group A and B with physiological saline (1 ml/kg), group C with mixed liquor of 2% lidocaine and compound Danshen injections and physiological saline (2:2: 16) and group D with mixed liquor of 2% lidocaine and triamcinolone acetonide injection and physiological saline (2:2:16), once a week for a total of three treatments. Four rats were killed every 1 week after injection for once, and the inflammatory factors of tumor necrosis factor (TNF-alpha), prostaglandin E2 (PGE2), interleukin-l (IL-1) and interleukin-6 (IL-6) were detected by ELISA method.
RESULTSThe levels of TNF-alpha, PGE2, IL-1 and IL-6 in compressed nerve tissues in group B were increased than those of group A (P < 0.01). The levels of PGE2, IL-1 and IL-6 in group C and D were decreased than those of group B, and group D was much less(P<0.05). There was no significant difference in level of TNF-alpha among group B, C, D (P > 0.05).
CONCLUSIONCompound compression with inflammatory stimulation can lead to massive release of inflammatory mediators, such as TNF-alpha, PGE2, IL-1 and IL-6. Both injection with compound Danshen injections and triamcinolone acetonide injections by sacral canal can reduce the levels of part inflammatory mediators (PGE2, IL-1 and IL-6), and the effect of Glucocorticoid is better than Danshen (P < 0.05).

Background Left ventricular hypertrophy(LVH) is a cardiovascular risk factor independent of the blood pressure. JAK/STAT pathway has been confirmed to participate in cardiac hypertrophy and hyperplasia. Our previous reports have shown that sodium tanshinone ⅡA sulfonate(STS) reversed LVH,inhibited the myocardial cells Ca2+ influx,lowered left ventricular myocardial tumor necrosis factor-?(TNF-?)and the proto-oncogene c-fos,Bcl-2,and p53 protein expression. Objective To study the effect of sodium tanshinone ⅡA sulfonate(STS) on JAK/STAT pathway in left ventricular hypertrophy(LVH) induced by abdominal aorta stenosis in rats. Methods Twenty-four 9-weeks-old rats submitted to abdominal aorta constriction,were randomized to receive STS 10 mg/(kg?d)(n=8)or sterilized distilled water (1 mL/d)(n=8),or valsartan 10 mg/(kg?d) by gavage(n=8),with age and sex matched sham operated rats(n=8) as control. HE,VG and immunohistonchemical staining were used to evaluate the myocardial fiber dimension(MFD). Expressions of JAK1 and STAT3 were assessed by using Western blot. Results Compared with the control group,pressure loaded rats had higher SBP[(117.3?8.3) vs LVH: (186.5?13.5)mmHg,P

Insulin-mediated glucose metabolism of peripheral tissue and liver was assessed by euglycemic hyperinsulinemia clamp technique in lipid-infused rats. There was a significant increase in plasma free fatty acids and a significant reduction in glucose infusion rates in the lipid-infused group. The suppressive effect of insulin on hepatic glucose production (HGP) was significantly blunted and the rate of glucose disappearance showed a slight decrease in the lipid-infused rats, suggesting that lipid impaired the abilities of insulin to suppress lipolysis, HGP and insulin-mediated glucose utilization in peripheral tissues.

Objective To observe the effect of acupuncture therapy of regulating Yin and Yang for the treatment of stroke,and to investigate the influence on plasma levels of calcitonin gene-related peptide(CGRP) and vascular endothelin(ET).Methods One hundred and twenty stroke patients were equally randomized into 3 groups: group A received acupuncture therapy of regulating Yin and Yang,group B received traditional body acupuncture therapy,and group C received scalp acupuncture therapy.One and a half months constituted one treatment course,and the treatment lasted 2 courses.The therapeutic effect was evaluated and the changes of plasma CGRP and ET levels were observed.Results The total effective rate was 95.0% in group A,85.0% in group B,and 82.5% in group C,the difference being significant between the three groups(P0.05).Conclusion Acupuncture therapy of regulating Yin and Yang exerts a certain effect for the treatment of stroke,and can up-regulate plasma CGRP level and decrease ET level.

Objective To evaluate the clinical applications of noninvasive mechanical ventilation in the treatment of acute cardiogenic pulmonary edema. Methods From Jan.2002 to Apr.2004 60 patients in Dalan Municipal Central Hospital were randomly assigned to receire conventional oxygen therapy or NMV supplied by a standard ventilator through a face mask,with adjustment of pressure support at 8-15 cm H_2O in addition to a positive end-expiratory pressure of 5-8 cmH_2O.Blood gas and vital signs were obtained at 1 h,2 h,3 h,4 h,and 12h.Results Endotracheal intubation was required in 5(16.7%)of 30 patients assigned to receire NMV and in 12(41.4%)of 29 assigned to receive conventional oxygen therapy(P=0037). Resolution time was significantly shorter in the NMV groupmedian 40(5~77)vs145(49~263)min,P
