The Scavenging Activites for O2- and OH of hydroxy-and-4-oxy Nitroxides
1999, 15(3): 179-181.
Abstract:
T he scavenging activities for and of 4-oxy-and-4-hydroxy-Nitrox ides and its derivatives(4-TEMPO) were studies. Superox ide anions()generated in a phenazin methosulphate(PMS)-NADH systtem were assayed by the reduction of mitroblue tetrazolium(N BT)Hydroxy radicals generated in“Fen ton reaction" were detected by spin-trapp ing technique NitroxIide free rad icals HTM PO、0TM PO and I-hydroxy I com pounds HTM POH、OTMPOH can scavenging during the cconcenentrations of 4-EMPO are 40-160μmol×L-1 The effect is clearly different from the control group(P< 0.05or p<0.01). HTMP、HTMPO and 1-hydrox-yl compounds can treduce the signal of DMPO-OH. during their concentrations are 16-160 mol×L-1, but the signal of DMPO-OH. ie raise HTMP and OTM P have no effect for OH. and whichindicated that them echnnism of scavenging may be related to the stopping radical-chain reation directly or analogy with superoxide dismutase(SOD). It is necessary that the mechanisms of effect for or DMPO of 4-TEMPO were studied further.

A casecontrol study of obesity and correlative factors for NIDDM
1999, 15(3): 199-200.
Abstract:
One hunched and ten pairs of cases and controLs from the first Hospital of Tianjing Mediacal University were analyzed in order to investigate the risk factors of non}nsulin-dependent diabetes mellitus( NIDDM) . The、onditional logistic; regression analysis results suggested that the fluctuation of previous weight is an important risk factor for NIDDM. The more the degree of Obeslty is and the earlier of the age Of Obeslty is the more or increases Among patlents Of previrous maximal body mass lndex(BMI) over 28kg/m2 the odds ratio is 11.52 tunes that of patlents having a previous body mass indes less than 25kg/ m2. Current waist girth, waist-high ratio( WTR),SBP are also important risk factors for NIDDM. After multiplead-justment previous maximal BMI, SBP, high serun TG remain the independent risk factors for NIDDM.

Abstract(1215)
Abstract:
To determine the prevalence of gout and hyperuricemia among the population in eastern coastline area Provice, the total of 17044 population in Rizhao of Shandong,Dong Ying,Weihai, and Shengli oil field were investigated. The serum uricacid was detected by Uricasetrindr method in a random sample that made up of 384 adult normal people. The results showed that crude prevalence of gout was 0.0352% and standardizell prevalence was 0.0315%,the ratio of standardized-prevalence in males to females was 1:0.415. The mean serum uricacid level was 289.6±76μmol/L in males versus 236.5±63.3μmol/L In felnales There was a slgnlfleant dlffelence between hales anci felnales The prevaalence of hyperuricemia was 5.79% in males and 2.44% in females. The result suggest hat the level of serumuric acid prevalence of hyperuricemia and gout among population of Shandong Province is signifi-candy lower than the cxmresponding level in European, American and Snutheaet Asia.

Abstract:
Based on the data from the survey of 7872 new lyrn aried cnuples who got the marriage 1icenses in two districts of Shanghai from Aug, 1987 to Aug.1988 and were folbwed up to the fifteen month after marriagrl we analyzed cxluples sex preferences for child effect Of sex preference on fertility behavior and factors affectings couples sex preferences More than half of couples( 54.9% of wives and 53.0%of hu shads) had no sex preferent for ch ild 20.9% of wives and 29.3% of husbads desired for boys and 25.9%of wives and 15.6%of hu shads desn'ed for daughter respectlvely T he main reasons for couples preference for a boy were boy is clever and could be cul tivated",to mairs the fan ilylisle and to save my faces by having a sori. Them airs reasons for couples preference for a girl were girl could take care of us when we get older and girl is more elegant and easy to be dressed up". coupies desired for son had higher percentage of desire for children Sex preference had aminor effect on couples fertility behaviorie thewaiting time for conception contraceptive use and fertility Status). The results of multinom ial logisiti regression showed that couples age at marriage, cnuples and their parents education couples occupation household income housing status husband had brother(s) or not and who was the deoision maker for fertility event affected couples sex preferences for child. Evidence indicates. that the further reduction in couples sex preference for child in Shanghai is no of significance in fanmily planning work.

Abstract:
We studied the correlatian of the hair areenic contents with age sex symptomatic degree from persons exposed arsenic in the area of coal type endemic arsenisn in Anlong county of Guizhou province The results showed that the hair arsenic cnntents of clinical and subclinical endem ic arsenism patents are over 20 tines higher than that of normal control and in the clinical patients their hair arsenic cnntents have an upward tendency according to the serious degrees of their symptoms the male hair arsenic contents in normal persons are obvpusly hgher than the female one but in the persons exposed arsenic there is not this phenoln enon and there is trend of the higher value of the female hair arsenic contents the hair arsenic cnntents in those feanale patients of arsenism icrease with the age which results In the trend of increasing hair arsenic contents with the age In all patients It suggests that the hair arsenic contents have a close re lation to the envi ronm entalpollution of coal acsenil and the obvious increasing of hair arsenic conmtents in thepeople of endeanic area is one of the main charactecistic of the existlng area of coal type endem icarsenism the periodic test of hair suitable to the direct inspect index in the endom icarea;among the residents without clinical symptoms in this area there are probably some subclinical endemic arsenism patients and the hair arsenic contents become much more important indicator for the judament of such kind of subclinical patients.
