Both aspirin and angiotensin converting enzyme(ACE)inhi bi tors are often used concomitantly in patients with cardiovascular disease.The s afety of the combination has been questioned. The potential antagonistic interac tions between ACE inhibitors and aspirin has become the focus of both increasing research and intense debate,with conflicting conclusions havin g been reported in the literature.We reviewed systematically available literatu re on the interactions between ACE inhibitors and aspirin in hyper- tension,acute myocardial infarction and congestive heart failure and found that further trials are needed to shed light on the effects and mechanism of interaction between these drugs.
2.OBSERVATION ON THE LEVELS OF BLOOD FREE RADICALS, SERUM LIPID PEROXIDE AND VITAMIN E IN NIDDM
Chinese Journal of Endocrinology and Metabolism 1986;0(04):-
Concentration of blood free-radicals in 19 normal subjects and 35 patients with NIDDM was estimated by electron spin resonance spectrometer. Serum lipid peroxide (Lpo) and vitamin E were measured with biochemical methods. As compared with controls, patients with NIDDM had significantly higher blood free-radical level and serum Lpo level. The results suggested that the metabolism of free-radicals was disturbed in NIDDM.

Objective:To observe the effect and influence of homocysteine and cystatin C in type 2 diabetes patients treated by Shuxuening injection combined with gliclazide. Methods: Type 2 diabetic patients were randomly divided into observation group and control group,and there were 30 cases in each group. The control group was given gliclazide hypoglycemic treatment, on the basis of the observation group to combined with Shuxuening injection. The course of treatment was 2 weeks. Efficacy , adverse drug reactions ,Ho-mocysteine ( Hcy) , Cystatin C ( CysC) and blood glucose ( FBG, PB) level change of two groups patients before and after treatment were compared. Results:The total effective rate of the observation group was 96. 67%, which was significantly higher than that of the control group (P<0. 05). After treatment,blood glucose and Hcy, CysC levels of the two groups of patients were significantly de-creased compared with before treatment (P<0. 05),and those of the observation group was much lower(P<0. 05). The incidence of adverse drug reactions between the two groups had no significant difference(P>0. 05). Conclusion:Shuxuening Injection on patients with type 2 diabetes mellitus has good curative effect, it can effectively reduce homocysteine and cystatin C levels, better control of blood glucose.

BACKGROUND: Studies have shown that OCT4, SOX2 and HIWI can express in tumor tissues. OBJECTIVE: To investigate the relationship between the expression of stem cell transcription factors SOX2 and OCT4 in esophageal squamous cell carcinoma and their clinical characteristics and prognosis. METHODS: Expression levels of SOX2 and Oct4 were detected using immunohistochemical SP method in 77 cases of esophageal squamous cell carcinoma and 40 cases of adjacent cancer tissues confirmed by pathological examination, and then the their relationship with prognosis and clinical characteristics of the patients was analyzed. RESULTS AND CONCLUSION: Significantly higher levels of SOX2 and Oct4 were found in the esophageal cancer tissues than the adjacent cancer tissues (P < 0.05). SOX2 and Oct4 were highly expressed in the esophageal cancer tissues isolated from poorly differentiated, lymph node metastasis patients (P < 0.05). During the 2-year follow-up, the median survival of patients positive for SOX2 and Oct4 was only 24 and 21 months, respectively, which was significantly lower than that of negative patients (30 and 33 months, respectively). These findings indicate that the highly expressed SOX2 and Oct4 in esophageal cancer tissues are associated with the differentiation, metastasis and prognosis of the patients with esophageal squamous cell carcinoma.

Objective To evaluate the efficacy and safety ofGuipi Decoction vs. antidepressants for depression. Methods Articles about the randomized controlled trials (RCTs) ofGuipi Decoction for depression were searched in the databases of CNKI, VIP, Wanfang Data, CMB, Embase, PubMed, and Cochrane Library. Two researchers independently screened the articles, extracted the data, and evaluated the methodological quality. Meta-analyses were performed by using RevMan 5.2 software.Results A total of 9 RCTs articles involving 893 cases were included. Meta-analysis results suggested that as compared with antidepressants only,Guipi Decoction together with antidepressants was associated with a significantly greater reduction in HAMD scores (MD=-4.63, 95%CI [-5.95, -3.32];P<0.001). There was no significant difference in HAMD scores betweenGuipi Decoction used alone and antidepressants (MD=-0.30, 95%CI [-4.22, 3.62];P=0.88). As compared with antidepressants,Guipi Decoction together with antidepressants increased in the rates of total effective events (RR=1.26, 95%CI [1.14, 1.38];P<0.001). No serious adverse reactions were reported. Meta-analysis results suggested that the incidence of adverse reactions of Guipi Decoction(RR=0.48, 95%CI [0.40, 0.58];P<0.001) andGuipi Decoction together with antidepressants (RR=0.51, 95%CI [0.30, 0.85];P=0.010) were lower than that of antidepressants alone.Conclusion The present evidence suggests thatGuipi Decoction is effective and relatively safe for patients with depression. However, because the quality of included research was low, more large-scale RCTs with multicenter and high quality are needed for further verification.

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective positive ion channel that is mainly expressed in sensory neurons and a member of transient receptor potential (TRP) family. The receptor could be activated by mechanical irritation, chemical irritation or endogenous ligand to mediate pains and cause injury to body functions. Traditional Chinese medicine believes that the mechanism of pain is that "stagnation leads to pain". Specifically, both of the contracture and tautness caused by cold and the blood stasis could result in blood impassability and pain. Most of traditional Chinese medicines for clearing heat and removing toxicity have the anti-inflammatory effect, while those for warming interior, and promoting blood circulation to remove blood stasis have the effect in smoothening blood vessels. Therefore, either with the anti-inflammatory effect or the effect in smoothening blood vessels, traditional Chinese medicines for clearing heat and removing toxicity, warming interior, and promoting blood circulation have the analgesic effect In this paper, the authors summarize the analgesic effect of the above three traditional Chinese medicines, with TRPV1 as the target.

Aim To study inhibitory effect of 5-fluorouracil encapsulated by galactosylceramide liposomes (5-Fu-GCL)on 5-Fu-resistent HepG_2 cells and its mechanisms. Methods Inhibitory effect of 5-Fu-GCL on established model of 5-Fu-resistant HepG_2 cells was assessed with MTT assay in vitro. The concentration-time course of 5-Fu-GCL in intracellular fluid was detected with high performance liquid chromatography (HPLC). Thymidylic acid synthase (TS) expression was observed with immunohistochemical method,and NO content was determined with chemical method. Results Obvious inhibitory effects of 5-Fu-GCL (75,150,300,600,1200?mol?L-1) on 5-Fu-resistant HepG_2 cells were observed with IC_ 50 of 158.6 ?mol?L-1,far lower than that of free 5-Fu (400.9 ?mol?L-1). 5-Fu-GCL (300 ?mol?L-1) inhibited 5-Fu-resistant HepG_2 cells in a time-dependent manner,and the inhibitory effect of 5-Fu-GCL was stronger than that of free 5-Fu during 12~48 h. Compared with free 5-Fu,5-Fu-GCL (300 ?mol?L-1) increased the content of intracellular fluid in 5-Fu-resistant HepG_2 cells. 5-Fu-GCL(62.5,300,1200 ?mol?L-1) not only inhibited the expression of TS,but also increased the production of NO in 5-Fu-resistant HepG_2 cells,and these effects of 5-Fu-GCL(300,1200 ?mol?L-1) were stronger than those of free 5-Fu. Conclusion 5-Fu-GCL has inhibitory effect on 5-Fu-resistant HepG_2 cells. The effect may be related to the increased concentration of 5-Fu-GCL in intracellular fluid,inhibited expression of TS and increased production of NO.
