Chinese Journal of Digestive Endoscopy 2012;29(11):612-614
ObjectiveTo investigate the relationship between colorectal neoplasia and nonalcoholic fatty liver disease (NAFLD).MethodsData of 809 patients who had undergone colonoscopy and epigastric CT scan in the same period were reviewed for gender,age,history of diabetes,hypertension,hyperlipidemia,NAFLD,colonoscopy and pathology results.Correlation of colorectal adenoma (CRA),colorectal carcinoma (CRC) and NAFLD were studied with multivariate Logistic analysis.Results NAFLD (P <0.0001,OR 2.06,95% CI 1.53-2.76) was the independent risk factor for CRA,where the incidence of CRA was higher than that in the control group.ConclusionPatients with NAFLD is the risk population of colorectal adenomas.

Objective To differentiate Chinese medical syndromes of chronic renal Failure by objective laboratory indexes. Method Data of 312 cases were collected through a retrospective survey and these cases were divided into five Chinese medical syndromes according to an authorized criterion. Laboratory examination indexes of all syndromes were disposed with analysis of variance and discriminant analysis in turn. Result Discriminant functions of four syndromes were worked out and the accuracy of the functions was 60%. Conclusion Differentiation of Chinese medical syndromes should use modern techniques for reference on the base of traditional methods. And through it, a new way even a new system of diagnosis for Chinese medical syndromes in which traditional and modern methods are perfectly combined may be found out.

The chemiluminescence reaction of amidopyrine-potassium permanganate with formaldehyde as an enhancer was investigated by flow injection system. A method for the determination of amidopyrine on the basis of this technique was proposed. The detection limit is 3.0×10-8 g/mL, the relative standard deviation is 1.3% (4.0×10-6 g/mL amidopyrine,n=11).The linear range is 1.0×10-7~8.0×10-5g/mL amidopyrine. The method has been applied to the determination of amidopyrine in the antondin injection.

Nerve agents (NAs) belong to the class of organic phosphorus compounds which are acetylcholinesterase ( AChE) inhibitors, including soman, sarin, tabun,VX, etc.NAs are extremely toxic and considered as the most danger-ous chemical warfare agents.The current standard treatment for poisoning by nerve agents consists of the combined adminis-tration of anticholinergic drugs such as atropine sulphate, AChE reactivators such as pralidoxime, obidoxime and HI-6 and diazepam for anticonvulsant effects, but oximes are therapeutic antidotes against nerve agent intoxications which exert the therapeutic purposes primarily by reactivating the NAs-inhibited AChE.In this paper, the mechanism of nerve agents, the main working procedure of anti-NAs drugs, the chemical structure of classic reactivator, the corresponding antitoxic action, in vivo and in vitro effects and metabolic kinetics are reviewed.

Objective To study the (-)-epigallocatechin-3-gallate (EGCG) function on the proliferation of T cells derived from the peripheral blood and synovial fluid of rheumatoid arthritis (RA) and RA-related cytokine levels and the role of EGCG on RA synovial fibroblasts (FLS) proliferation was investigated. Methods ① Mononuclear cells from RA peripheral blood (30 cases) and synovial fluid (23 cases)were isolated. Blank group, negative control group, positive control methotrexate (MTX) group and therapeutic group with three different concentrations of EGCG were set up. Incorporated isotope 3H was used to test T cell proliferation from RA-PBMC and SFMC. ELISA assay was used to test cytokine (TNF-α, IFN-γ, IL-1, IL-6 and IL-17A) levels. ② MTT assay was used to test FLS proliferation from RA synovial tissue (8 cases).Results ① The CPM value of the high-dose group of EGCG in the peripheral blood and synovial fluid of RA patients was [ ( 15 136±2910), ( 11 587±3135 ) ], which was declined significantly than the control group (42856±2127) (P<0.01). The levels of TNF-α, IFN-γ, IL-1, IL-6 and IL-17A in the high-dose group of EGCG in the peripheral blood were [(321±13), (298±20), (132±12), (197±7), (59±8) pg/ml], which were decreased significantly than those of the control group [ (458±28), (505±26), (346±28), (405±25),(109±13) pg/ml ] (P<0.05 or P<0.01 ). The levels of TNF-o, IFN-γ, IL-1, IL-6 and IL-17A in the highdose group of EGCG in the synovial fluid were [(41.4±2.9), (182±16), (56.3±11.0), (34.2±1.9), (44±8)pg/ml ], which was decre-ased significantly than the control group [ ( 388.3± 19.3 ), (469±20), ( 104.2±17.8 ),( 114.5±4.8), ( 104±11 ) pg/ml] (P<0.05 or P<0.01 ). ② The level (A) of the high-dose group of EGCG in the FLS was (0.08±0.02), which was declined significantly than the blank group (0.27±0.04) (P<0.05).Conclusion ① In vitro EGCG can inhibit T cell proliferation from peripheral blood and synovial fluid of RA patients and the TNF-α, IFN-γ, IL-1, IL-6 and IL-17A secretion are decreased. ② In vitro EGCG can inhibit the proliferation of RA FLS.

Objective To investigate the effect of hypertension and hyperuricemia (HUA) on renal function.Method Total 1 209 subjects undergoing health check up from December 2000 to December 2002 and 45 patients with renal disorders were enrolled in the study.The blood pressure,height,weight,renal function and liver function were measured; and the glomerular filtration rate (GFR) was calculated.The GFR in patients with hypertension,HUA and hypertension with HUA was compared.Results The incidence of hypertension in HUA group and non-HUA was 23.9% (58/243) and 13.9% (134/966),respectively (x2 =14.52,P =0.000).GFR in HUA with hypertension,HUA and hypertension groups were (69.1 ± 30.5),(82.8 ± 25.3) and (90.1 ± 21.7) ml · min-1 · (1.73 m2)-1,respectively (P < 0.01).Logistic regression analysis showed that the risk factors for GFR were UA,systolic pressure and age.After 5 years of follow up,GFR in hypertension group was significantly decreased from (90.7 ± 18.1) to (85.6 ± 17.6)ml·min-1 · (1.73 m2)-1m,in HUA group from (86.3±10.9) to(62.1 ±8.2) and inHUAwith hypertension group from (77.9 ± 18.9) to (49.3 ±9.8) ml · min-1 · (1.73 m2)-1,UA and age were the long-term factors that affect GFR (P < 0.05).Conclusions Both hyperuricemia and hypertension can impair the kidney function,if hypertension is complicated with hyperurecemia the effect is more marked.
