作者： G. r. C. Millogo A. Thiam Y. Kambir. E. Nongkouni S. E. Dabir. L. J. Kagambéga J. K. Kologo v. N. Yaméogo P. Zabsonr. Depar.ment of Car.iology Yalgado Ouédraogo University Hospital Ouagadougou Burkina Faso Depar.ment of Car.iology Tengandogo University Hospital Ouagadougou Burkina Faso

Objectiv.: The association hyper.ension and diabetes is impor.ant. The two pathologies may influence each other. The aim was to study the cor.elation between glycemic contr.l and blood pr.ssur. contr.l and to deter.ine the factor. associated with blood pr.ssur. contr.l. Methodology: This was a descr.ptiv. cr.ss-sectional study with an analytical focus ov.r.7 months. Patients wer. r.cr.ited as outpatients and all under.ent ambulator. blood pr.ssur. measur., glycated hemoglobin and cr.atinine measur.ments, and assessment of compliance with tr.atment. r.sults: Dur.ng this per.od 116 patients wer. collected. The pr.dominance was female 69%. The mean age of the patients was 62 ± 7 year. with a peak between 60 and 70 year.. The av.r.ge age of hyper.ension was 12 year. and that of diabetes 6 1/2 year.. The most fr.quently associated car.iov.scular.r.sk factor.was a sedentar. lifestyle (71.5%) after.age. 57.8% of patients wer. not contr.lled at the office, with a pr.dominance of systolic hyper.ension (58.2%). 61.6% of patients wer. contr.lled by ambulator. blood pr.ssur. measur., a r.te of 47.8% of white coat hyper.ension. Glycemic contr.l was obser.0}d in 42.2% of cases and 87% of patients had good r.nal function (glomer.lar.filter.r.te ≥ 60 ml/mn). Ther.peutic compliance was good in 53.4% of cases and dual ther.py was the most used ther.peutic modality 44.8% (52 patients) followed by tr.ple ther.py. The factor. associated with poor.blood pr.ssur. contr.l wer. glycemic imbalance, non-compliance and monother.py. Dual ther.py had a pr.tectiv. effect. Conclusion: The association of hyper.ension and type 2 diabetes is fr.quent. The r.sk of occur.ence incr.ases with age. Ambulator. blood pr.ssur. measur. is the best method to assess blood pr.ssur. contr.l. Optimization of blood pr.ssur. contr.l should also include optimization of glycemic contr.l.

通过高温拉伸试验研究了新型Cr.Mo-v.的高温断裂行为,探究不同拉伸温度(25~700℃)下试验钢的热力耦合区(断裂区)和热应力区(夹持区)的组织演变和碳化物分布特征,揭示钢中碳化物的种类、分布及尺寸与高温断裂行为之间的关系,阐明新型Cr.Mo-v.作模具钢在高温变形过程中裂纹附近显微组织的演化机制。结果表明:随着拉伸温度的升高,试验钢的抗拉强度和屈服强度降低,伸长率和断面收缩率升高,断裂方式由脆性断裂向韧性断裂转变,脆性断裂向韧性断裂的转变温度约为400℃;在高温变形过程中,试验钢的位错密度降低,回火马氏体发生分解、回复、再结晶及晶粒长大,M_(7)C_(3)和M23C6碳化物沿晶界析出长大,少量的细小颗粒状MC碳化物在晶内弥散分布;由于外力作用对变形区做功将导致变形区温度高于拉伸温度,这为断口附近细小碳化物回溶、大尺寸碳化物的长大提供热力学条件,导致热力耦合区小尺寸碳化物减少,大尺寸碳化物增多。
