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.

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.

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 relationship between oxidative stress and endothelial cell apoptosis in patients with obstructive sleep apnea-hypoventilation syndrome (OSAHS). Methods Sixth-seven patients definitely diagnosed by potysomnography (PSG) as OSAHS were divided into three groups according to their apnea-hypoventilation index (AHI), 14 in mild group (5 < AHI≤20), 21 in moderate group (20 < AHI≤40) and 32 in severe group (AHI 40). And, 18 healthy persons (AHI <5) were recruited as controls. Blood samples were obtained form all of them after PSG performance for measuring apoptotic endothelial cells (CD146AnnV+) and serum levels of superoxide dismutase (SOD) and malondialdehyde (MDA). Results Serum level of MDA and CD146AnnV+ in moderate and severe OSAHS group were significantly higher than those in control group (all P < 0.05). Serum level of SOD in moderate and severe OSAHS group was significantly lower than that in control group (P < 0.05). CD146AnnV+ correlated positively with AHI, the longest apnea time (LAT) and oxygen desaturation index (ODI) (r = 0.778, 0.609 and 0.689, respectively, all P < 0.05) and correlated reversely with saturation of arterial blood oxygen at night (SaO2min) (r =-0.635, P < 0.01). CD146AAnnV+ correlated positively with serum level of MDA (r = 0. 698, P < 0.01), and correlated reversely with serum level of SOD (r =-0.705, P < 0.01). Results of linear multivariate regression analysis showed that AHI, serum levels of SOD and MDA were independent risk factors for endothelial cells apoptosis in patients with OSAHS. Conclusions There existed oxidative stress due to intermittent hypoxia in patients with OSAHS, which could be one of the major causes in exacerbating endothelial damage.

ObjectiveTo investigate the role and mechanism of cervical sympathetic ganglia block in alleviation of cerebrovascular spasm (CVS) of rabbits after subarachnoid hemorrhage ( SAH ).Methods A total of 18 healthy male white rabbits whose cervical sympathetic ganglia were successfully blocked were randomly divided into three groups:sham operation group (Group A),SAH group (Group B) and SAH with cervical sympathetic ganglia block group (Group C).Venous blood (2 ml) and cerebrospinal fluid (2 ml) were obtained before the first blood injection ( T1 ),at 30 minutes after injection ( T2 ) and at day 7 after injection ( T3 ),respectively,and conserved in a low temperature refrigerator for spare use.Basilar artery value at T1,T2 and T3 was measured via cerebral angiography.The degree of damage to nervous system at T3 was recorded.ResultsThere was no significant difference in diameter of basilar artery at T1 among three groups.At T2 and T3,the diameters of basilar artery of Groups B and C were shorter than that of Group A,with Group B shorter than Group C,with statistical differences ( P ＜0.01 ).There were no significant differences in NO and NOS in plasma and cerebrospinal fluid at T1 among three groups (P＞0.05).NO and NOS contents at T2 and T3 were lower than those at T1,with Group A lower than Groups B and C,with statistical differences (P＜0.01 ).At T3,the nerve function of Groups B and C were better than that of Group A,with Group C better than Group B ( P ＜0.01 ).Conclusion Cervical sympathetic ganglia block relieves CVS,increases NO content and NOS activity in plasma and cerebrospinal fluid and promotes neural functional recovery after SAH.

The geo-herbalism of Cangzhu, Atractylodes lancea (Thunb.) DC. , was studied for itsstrict quality control. Samples of typical and representative populations of geo-herbal and non-geo herbalorigin were collected, examined and cultivated through field work. Volatile oils from samples of varioushabitats were determined by GC/MS, and their respective bacteriostatic minimum inhibitory concentration(MIC)determined. Results of the study showed that both the size of capitulum and cleft on the leaves var-ied greatly even in species of the same population. The main components in their volatile oil also variedgreatly with Maocangzhu (MCZ) contains atractylone (29.54%) and atractylodin (17.82%); that of Nan-cangzhu (NCZ) contains hinesol (61.86%) and β-eudesmol (19.79%), and Baicangzhu (BCZ) cantains βeudesmol or mixture of β-eudesmol and atractylone (over 30%). Volatile oils of speciaes from Luotina,Taibai, and Huanglong showed potent bacteriostatic activity against Streptococcus hemolyticus (SH), com-parable to penicillin or streptomycin. In conclusion, A. lancea is a polymorphic complex greatly influencedby geographic environment and a reasonable proposal is to name them by geo-herbal names such as: MCZas A. lancea var. maoshanensis Hu et Feng; NCZ as A. lancea subsp. luotianensis Hu et Feng; and BCZ asA. lancea var. chinensis (Bunge) Kitam other than independent species as A. chinensis Bunge. It was in-correct to say that MCZ has no atractylone in its volatile oil and therefore differs from A. macrocephalaKoidz. (Baizhu). Inhibitory activity of the volatile oils against SH and Pseudomonas aeruginosa (PA) arealso quite different due to the habitats and imply that the rhizome from Luotian may be used to cure infec-tion diseases caused by SH and PA besides their traditional uses.

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.
