Objective To study the subchronic toxicity of fipronil in rats and to protect and improve the environment and human health. Methods 80 SD rats were randomly divided into four groups,20 in each groups (10 males and 10 females). The rats were treated with fipronil by gavage,in doses of 25,10,4,0 mg/kg,once a day,10 ml/(kg?d),for 90 consecutive days. The test method was according to GB15670—1995. Results The acute toxicity symptom of rats in high dose showed that cachexia,dull,hair floppy. No acute toxicity symptoms were found in the moderate and low dose groups. No significant difference was found in the serum and urine routine test indexes. Liver index increased significantly in the high dose(25 mg/kg)and moderate dose(10 mg/kg) exposed rats. The activity of aspartateaminotransferase (AST) in the serum increased only in male rats. No significant changes in indicators were found in the low exposed rats. The histopathologic examination showed that in the high and moderate dose groups,in the liver,spot and focus necrosis,the hepatocytes around central veins became bigger and cloudy swelling,some hepatocytes presented ballooning degeneration. No obvious pathological change was seen in the low dose group. Conclusion Fipronil has a toxicity to the liver,based on 90 day oral toxic test in rats,no-observed adverse effect level (NOAEL) is 4 mg/(kg?d).

ObjectiveTo evaluate the risk of colorectal neoplasia among patients with gastric or duodenal adenoma.MethodsWe retrospectively reviewed 39 patients with gastric or duodenal adenomas between 2007 and 2011 as the study group.A total of 78 patients without upper gastrointestinal adenomas who underwent colonoscopy were included as a control group.Colonoscopic findings were compared between the two groups.ResultsPositive finding rate of colorectal neoplasia in study group was 51.3％ (20/39),with adenomas in 38.5％ (15/39) and cancer in 12.8％ (5/39),which were all significantly higher than those of the control group,14.1％ (11/78) ( P ＜ 0.001 ),12.8％ ( 10/78 ) ( P ＜ 0.05 ) and 1.3％ ( 1/78 ) ( P ＜ 0.05),respectively.The results were similar when upper digestive tract was further divided into stomach and duodenum(50.0％ vs.12.5％ and 52.2％ vs.15.2％ ).ConclusionPatients with gastric or duodenal adenomas are at a significantly higher risk for colorectal neoplasia.Colonoscopy should be recommended for these patients.

OBJECTIVE:To explore the effects and safety of Hedan tablets on the levels of blood lipid,inflammatory factors and oxidative stress in coronary heart disease(CHD)patients with type 2 diabetes mellitus(DM2). METHODS:A total of 118 pa-tients diagnosed as CHD with DM2 were collected from our hospital during Jul. 2013-Nov. 2015,and then divided into observation group(63 cases)and control group(55 cases)according to random number table. Control group received conventional treatment such as controlling blood glucose,regulating blood lipid,vasodilator,anticoagulant. Observation group additionally received He-dan tablets 1.46 g before meal,tid,on the basis of control group. Both groups received treatment for 6 months. The levels of blood lipid (TC,TG,LDL-C,HDL-C),serum inflammatory factors (TNF-α ,IL-10,IL-6,hs-CRP) and oxidative stress indexes (MDA,SOD,NO)before and after treatment as well as the occurrence of ADR were compared in 2 groups. RESULTS:Before treatment,there was no statistical significance in levels of blood lipid,serum inflammatory factors or oxidative stress indexes be-tween 2 groups(P>0.05). After treatment,the serum levels of TC,TG,LDL-C,TNF-α,IL-6,hs-CRP and MDA in 2 groups were decreased significantly,while those of IL-10,SOD and NO were increased significantly;the observation group was signifi-cantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Hedan tablets can effectively improve the level of blood lipid,reduce the lev-el of inflammatory factors,relieve inflammatory injury,reduce the level of oxygen free radical,strengthen antioxidant capacity and lighten oxidative stress injury with good safety.

In order to explore the method to prepare hypoxia UW solution and the stability and preservation of hypoxia UW solution, UW solution was purged by argon or air for 15 min or 60 at a flow rate of 0.8 or 2 L/min, and the oxygen partial pressure of UW solution was detected. The hypoxia UW solution was exposed to the air or sealed up to preserve by using different methods, and the changes of oxygen partial pressure was tested. The results showed that oxygen partial presure of 50 mL UW solution, purged by argon for 15 min at a flow rate of 2 L/min, was declined from 242+/-6 mmHg to 83+/-10 mmHg. After exposure to the air, oxygen partial pressure of hypoxia UW solution was gradually increased to 160+/-7 mmHg at 48 h. After sealed up by the centrifuge tube and plastic bad filled with argon, oxygen partial pressure of hypoxia UW solution was stable, about 88+/-13 mmHg at 72 h. It was concluded that oxygen of UW solution could be purged by argon efficiently. Sealed up by the centrifuge tube and plastic bag filled with argon, oxygen partial pressure of UW solution could be stabilized.
