ABSTRACT
Objective To assessthe association of polymorphism in angiotensin converting enzyme insertion/deletion (ACE I/D) gene with curative effect of hypotensive drugs.Methods The studies concerning association of ACE I/D with curative effect of hypotensive drugs were retrieved by searching data base,and then screened according to inclusive and exclusive criteria.Meta-analysis was performed by review manager 5.3 software.WMD and OR were used to assess difference of levels or effective rate of blood pressure degression among DD,DI and Ⅱ gcnotype.Results Totally 12 articles with 2 528 patients were included in this study.For all patients,WMD (95％ CI) with DD:Ⅱ genotype reflecting degression level of systolic pressure (SP) and diastolic pressure (DP) were respectively 5.92(4.09～7.75) and 1.70(1.03～ 2.38),and OR (95％CI) reflecting effective rate of blood pressure degression was 2.49 (1.44～ 4.31),with statistical significance (P＜ 0.05).For subgroup analysis according to hypotensive drugs,using angiotensin Ⅱ receptor blocker (ARB),WMD (95 ％CI) of SP and DP were respectively 9.16(6.51～11.82) and 1.84(0.10～3.57) in DD:Ⅱ,or 6.75(4.21～9.28) and 3.38(0.16～6.61) in DI ∶ Ⅱ genotype,all with P＜0.05.There were no statistical significance for diuretic in DD ∶ Ⅱ,DD ∶ DI and DI ∶ Ⅱ.Using angiotensin converting enzyme inhibitor (ACEI),OR (95％CI) were respectively 3.79(1.80～8.01) and 2.97(1.34～6.55) in DD:Ⅱ and DD:DI,with P＜0.05.Conclusion Compared with I allele in patient,ACEI and ARB were more effective for D allele,while there were no difference for curative effect of diuretic between I allele and D allele.
ABSTRACT
Objective To evaluate the role of serum homocysteine (HCY) in diabetes mellitus(DM ) complicating proliferative diabetic retinopathy (PDR) .Methods 174 patients with DM were selected and divided into PDR ,non‐PDR(NPDR) and non‐dia‐betic retinopathy (NDR) groups .The serum HCY level was detected .Results Serum HCY levels in the PDR ,NPDR and NDR groups were (18 .20 ± 5 .60) ,(14 .40 ± 6 .70) and ,(12 .10 ± 6 .80)μmol/L respectively ,which was highest in the PDR group (P<0 .05) .Conclusion HCY could result in PDR generation possibly by injuring the retinal blood vessels .
ABSTRACT
Objective To investigate the role of rheumatoid factor(RF) ,C‐reactive protein(CRP) ,erythrocyte sedimentation rate (ESR) in the diagnosis of rheumatoid arthritis(RA) .Methods 74 RA patients and 90 patients with symptoms similar to RA were recruited in the study randomly .Blood samples were detected for the levels of RF ,CRP ,ESR .The results were compared between two groups .Receiver operating characteristic curve(ROC) was used to access the diagnostic efficiency .Results The levels of RF , CRP ,ESR of RA group were (271 .4 ± 560 .9)IU/mL ,(28 .7 ± 35 .6)mg/L ,(60 .9 ± 40 .1)mm/h ,respectively ,and were higher than those of control group which were (56 .8 ± 189 .3)IU/mL ,(15 .4 ± 24 .7)mg/L ,(45 .1 ± 33 .1)mm/h respectively .ROC analysis re‐vealed that the AUC of RF ,CRP ,ESR and combined detection of the 3 factors were 0 .784 ,0 .666 ,0 .615 ,0 .757 ,respectively with statistical significance(P<0 .05) .Conclusion RF ,CRP ,ESR are useful in the diagnosis of RA ,and RF has the highest diagnostic ef f iciency .
ABSTRACT
Objective To evaluate the association between matrix metalloproteinase‐1 (MMP‐1)‐1 607 bp 1G/2G and matrix metalloproteinase‐3(MMP‐3)‐1 171 bp 5A/6A polymorphisms in promoter regions and susceptibility to ovarian cancer by Meta‐a‐nalysis .Methods Case‐control studies with regards of relationship between MMP‐1‐1 607 bp 1G/2G ,MMP‐3‐1 171 bp 5A/6A pol‐ymorphisms in promoter regions and susceptibility to ovarian cancer were searched in electronic databases .Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the association between polymorphisms and susceptibility .RevMan5 .0 software was applied for data analysis .Results Eight studies ,containing 5 studies for MMP‐1 and 3 studies for MMP‐3 ,were selected .For MMP‐1‐1 607 bp 1G/2G ,OR(95% CI)=0 .95 (0 .74-1 .21) ,P=0 .67 under 1G/1G :1G/2G+2G/2G model ,OR(95% CI)=0 .93 (0 .70-1 .23) ,P=0 .60 under 1G/1G :2G/2G model ,OR(95% CI)=0 .99 (0 .87-1 .14) ,P=0 .91 under 1G :2G model;for MMP‐3‐1 171 bp 5A/6A ,OR(95% CI)=0 .97(0 .68-1 .38) ,P=0 .85 under 5A/5A+5A/6A :6A/6A model .Overall ,there was statisti‐cal significance .Conclusion It is still not confirmed that significant association between the MMP‐1‐1 607 bp 1G/2G and MMP‐3‐1 171 bp 5A/6A polymorphisms in promoter regions and susceptibility to ovarian cancer exists in current literature .

Objective To evaluate the association of angiotensin (AGT ) gene M235T polymorphism with essential hypertension (EH) .Methods The literatures examining the association of the M 235T polymorphisms with EH were selected in electronic data-bases .Using RevMan5 .0 ,heterogeneity and pooled effect sizes were calculated .Results Totally ,29 articles ,with 5 971 cases and 6 443 controls were finally included in this study .The odds ratio (OR) value of TT+ TM∶MM genotype was 1 .13 (95% CI 1 .00-1 .25 ,P=0 .04) in worldwide populations .Subgroup analysis showed that the OR values of TT ∶MM genotype were 1 .13 (95% CI 0 .90-1 .42 ,P=0 .28) in subjects published before 2008 and 1 .29(95% CI 0 .94-1 .75 ,P=0 .11) in those after 2008(year of 2008 included) .The OR values of T ∶M in Han population was 1 .24 (95% CI 1 .01-1 .53 ,P=0 .04) .Conclusion TT+ TM genotype of the M235T polymorphisms is associated with EH in worldwide populations ,and T allele is also correlated with EH in Han popu-lation .
ABSTRACT
Objective To analyze surgical diagnosis and treatment effect of 25 cases with gastric stump carcinoma.Methods The clinical manifestations and therapies of 25 cases with gastric stump carcinoma in our hospital from 1992 to 2003 were analyzed retrospectively.We sum up the surgical methods and postoperative survival rate.Results The postoperative survival rates of 1,3 and 5 years in 25 cases with gastric stump carcinoma were 60.2%,34.2% and 18.6% respectively,and were 81.4%,48.2% and 36.7% respectively in cases treated with radical resection.Conclusion No specific symptoms were identified,endoscopy examination periodically is the key point to detect gastric stump carcinoma.Radical resection is the most effective surgical style for surgical treatment of gastric stump carcinoma.
ABSTRACT
Objective: To study the protective effect of ? carotene in anoxia injured cardiomyocytes. [WT5FZ]Methods: The cultured rat neonatal cardiomyocytes were subjected to 2h anoxia and the changes of lactate dehydrogenase(LDH) activity, malondialdehyde (MDA), oxygen free radical (OFR) contents and superoxide dismutase (SOD) activity were detected. The effects of pre treatment with ? carotene were then investigated. Results: The LDH, MDA, OFR and SOD of cardiomycytes were changed significantly after 2h anoxia (P
