Hypertension is a global problem,affecting both developed and developing nations. The mor-bidity of hypertension in children and adolescents has increased year by year in recent years. Hypertension in children can cause target organ damages(mainly renal,cardiovascular,central neurological,or optic fundal). In clinical practice,we need to find simple and easy methods for early recognition of target organ damages,thus se-rious consequences in adult hypertension may be prevented.

Objective To investigate the relationship of character of atherosclerotic plaque in carotid artery and serum CRP level. Methods The atherosclerotic plaques in carotid arteries were confirmed by multislice CT angiography(MSCTA),in which serum CRP level were detected in 28 patients with cerebral thrombosis,24 patients with lacunar infarction and 19 patients with TIA in internal carotid artery system in order to analysis the relationship between character of plaque and serum CRP level. Results (1)Mixed plaque and soft plaque were mainly found in cerebral thrombosis and TIA groups, while rigidity plaque was mostly found in lacunar infarction group, there were significance difference in plaques distribution among three groups(all P0.05).(3) CRP level in different groups was (4.546?2.720)mg/L in soft plaque group, (3.951?1.863)mg/L in mixed plaque group respectively,those were both higher than that of the rigidity plaque group[(2.762?1.323)mg/L],and there was significance difference between them(all P

ObjectiveTo observe the curative effect of alprostadil combined with cilostazol in treatment of patients with lower limb atherosclerosis.MethodsSixty-two patients with lower limb atherosclerosis were divided into cilostazol group (cilostazol 100 mg,2 times a day,oral) and therapeutic alliance group (cilostazol 100 mg,2 times a day,oral; alprostadil 10 μ g dissolved in 100 ml intravenous infusion of 0.9％ sodium chloride,once a day) by random number table with 31 cases each.The changes of ankle-brachial index (ABI),distance of 6-minute walk test(6-MWT) and the dorsal blood flow were compared before and after treatment.Results | After treatment,the distance of 6-MWT,ABI and the level of dorsal blood flow were significantly improved in two groups (P ＜ 0.05 or ＜ 0.01 ).Distance of 6-MWT and the level of dorsal blood flow in therapeutic alliance group was significantly higher than that in cilostazol group after treatment [(425.4±138.5) m vs.(379.5±124.6) m,(0.77±0.18) ml/ (s·cm2) vs.(0.66±0.14) ml/( s· cm2)] ( P＜0.05 ).The total effective rate in the treatment of cold feel in therapeutic alliance group was significantly higher than that in cilostazol group [ 87.5％(21/24) vs.61.9％( 13/21 ) ](P＜ 0.05).Conclusion Alprostadil combined with cilostazol is safe and effective in treating lower limb atherosclerosis.

Methods The data of of 142 patients with laparoscopic myomectomy were analyzed retro-spectively. According to the different suture methods,they were divided into inverting suture group (85 cases) with straight mattress inverting suture and 8-character-pattern suture group (57 cases). The operation time, intraoperative bleeding, postoperative complications between two groups were compared. Results The operation time and intraoperative bleeding of varus suture group were less than those of 8-character-pat-tern suture group, single tumor posterior uterine wall parts of operation time and intraoperative bleeding than patients with the anterior wall of the uterus and uterine bottom, 1 cases of pelvic related operation infection after operation in eight suture group,abdominal and pelvic mucosa adhesion in 2 cases,the complication rates between two groups were statistically difference (P<0. 05). Conclusion Laparoscopic myomec-tomy with direct mattress inverting suture can shorten operation time, play a good hemostasis in the operation and reduce the incidence of pel-vic infection and abdominal and pelvic mucosa adhesion.

OBJECTIVE:To study the association between the reticulated platelets(RP) percentage and aspirin resistance(AR) with the percentage of reticulated platelets in whole blood representing the platelets turnover rate to illuminate the influence of platelets turnover rate on AR.METHODS:The RP percentage and arachidonic acid(AA) and adenosine diphosphate(ADP)-induced platelet aggregation in 80 patients after receiving aspirin(100 mg?day) for no less than 7 days were determined.The patients were divided into AR group,aspirin semi-resistance(ASR) group,and aspirin sensitive(AS) group,and the RP percentage in the three groups were compared.RESULTS:RP percentages in AR,ASR,and AS groups were(4.11?2.62)%,(2.23?1.79)%,and(2.18?1.24)%,respectively,showing signficant differneces between AR group and AS group(P0.05).CONCLUSION:Increased platelets turnover may induce AR,therefore,the patients with coronary artery disease should receive aspirn for multiple daily(antiplatelet therapy) or to take controlled release or sustained release aspirin.The safety and efficacy of these therapies should be confirmed in clinical trials.

Objective To investigate the role of mutation of insulin receptor(IR) gene on the development of ischemic cerebral vascular disease.Methods The base variations at exon 17 and 20 of IR gene, by means of PCR SSCP were determined in the 68 cases of atherothrombotic cerebral infarction (ACI), 81 cases of lacunar infarction (LI) and 62 healthy controls.Results There were two alleles of T and C at exon 17 of IR gene. The prevalence of mutant of T allele in ACI patients was more common than that in the controls. The blood pressure and the parameters of blood sugar,lipid metabolism in the patients with mutant were higher than those in the controls with wild type gene. The correlative analysis showed the polymorphism of IR gene was not related statistically to the blood pressure. No base variation at exon 20 was found in the study.Conclusion By promoting the development of atherosclerosis,the mutation at exon 17 of IR gene may participate in the occurrence of ischemic stroke.
