Methods The blood lipid (TG, TC, LDL, and HDL) levels in 200 asymptomatic individuals with high uric acid (A group) and 200 sex-and age-matched ones with normal serum uric acid (B group) were examined and the results of the two groups were compared. Results The concentration of triacylglycerol, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were (3.09±0.98), (4.05±1.07), (3.38±0.98), and (1.30±0.51) mmol/L, respectively in group A; and were (1.65±0.86), (3.99±0.99), (2.97±0.89), and (1.41±0.66) mmol /L, respectively in group B. The concentration of TG in group A was obvious higher than that in group B (Plt;0.01). However, the differences of their total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were not significant (Pgt;0.05). The increase of TG was obvious compared with TC(Plt;0.01), LDL (Plt;0.01), and HDL (Plt;0.01) in group A; while the comparisons in group B were not significant (Pgt;0.05). Conclusion Uric acid metabolism correlates with triacylglycerol metabolism.
目的 對(duì)注射用甲哌卡因在口腔臨床局部麻醉應(yīng)用中的有效性及安全性進(jìn)行評(píng)價(jià).方法 采取平行組設(shè)計(jì)、分層隨機(jī)、雙盲、多中心臨床試驗(yàn)方法.對(duì)照劑為含腎上腺素2%利多卡因,納入病例包括上頜全部及下頜前牙區(qū)牙齒中牙髓炎或需要拔除牙齒的患者.結(jié)果 除17例外, 127例符合納入標(biāo)準(zhǔn),試驗(yàn)組66、對(duì)照組61例;口腔內(nèi)科60、口腔外科67例,男性55、女性72例,年齡20 ～65歲,平均38.84±12.06歲.在唇頰側(cè)根尖區(qū)牙槽局部粘膜下浸潤(rùn)1.5毫升甲哌卡因,起效 中位時(shí)間與對(duì)照組一樣都是60秒鐘,麻醉持續(xù)時(shí)間146.7分鐘,中位時(shí)間125分鐘.可成功進(jìn)行牙髓治療及拔牙操作.試驗(yàn)組81.82%病例術(shù)中完全無(wú)痛,15.15%微痛但能順利完成操作, 優(yōu)良率達(dá)到96.97%.甲哌卡因組9例(13.64%)注射后收縮壓短暫升至145～162 mm汞柱,5例 (8.33%)舒張壓短暫升至91～93mm汞柱.心率略有升高,1例注射甲哌卡因后半分鐘至一分鐘心悸,不需處理.上述反應(yīng)多與藥物中所含腎上腺素有關(guān).無(wú)過(guò)敏反應(yīng)發(fā)生. 結(jié)論 甲哌卡因是一種安全可靠、麻醉效果好的口腔用局部麻醉劑.
