多重聚合酶链反应快速诊断感染性眼内炎的研究

目的 探讨多重聚合酶链反应（MPCR）快速诊断细菌性、真菌性眼内炎及混合感染的价值。 方法 MPCR法检测常见致病性细菌和真菌菌株，并检测38例患者41只眼（双眼3例，单眼35例）眼内液标本，与细菌和真菌培养结果比较。 结果 MPCR法5 h即可检测出标本中微量细菌和真菌，41份标本MPCR检测阳性34份（82.9％），其中细菌阳性26份，真菌阳性6份，细菌和真菌均为阳性2份，MPCR阳性率明显高于细菌或真菌培养 （χ2＝9.60,P＜0.05）。 结论 MPCR速度快、敏感性和特异性高，有助于细菌性和真菌性眼内炎的快速明确诊断。 （中华眼底病杂志，2004，20：81-83）

Infected endophthalmitis diagnosed by multiplex polymerase chain reaction

Objective To evaluate the rapid diagnosis of bacterial and (or) fungal endophthalmitis by multiplex polymerase chain reaction (MPCR). Methods MPCR was performed to detect the DNA segment of bacteria and (or) fungi from standard strains and 41 samples of intraocular fluid or vitreous from 38 patients (3 with double eyes and 35 with single), and the results were compared with the cultured bacteria and fungi. Results Five hours after detected by MPCR, bacteria and (or) fungi in 34 out of 41 samples (82.9%) from patients were detected，in cluding bacteria in 26，fungi in 6，and both bacteria and fungi in 2. The positive rate of MPCR was obviously higher than the cultured ones（χ2＝9.60, P＜0.05）. Conclusion With the advantages of rapidity, sensibility, and specificity, MPCR can make for the rapid and definitive diagnosis of bacterial and (or) fungal endophthalmitis.
