Methods In 50 cases of patients after treatment of artificial kidney and 54 healthy volunteers, the prevalence of HHV-7 in peripheral blood mononuclear cell and cell-free viral DNA in plasma was tested by nested polymerase chain reaction assay; the product of PCR was digested by restricted enzyme EcoR I to identify its specificity.

采用巢式聚合酶链反应对50例肾透析病人和54例正常健康人PBMC和血浆标本中HHV-7 DNA进行定性检测；用限制性核酸内切酶EcoRⅠ对PCR产物进行酶切图谱分析以确定扩增产物的特异性。

Objective: To explore the sensitivity of reverse transcriptase polymerase chain reaction method for detection of Coxsackie virus B3 (CoxB3) infection.

The treadmill training of T-group rats were continuously trained for 4~6 weeks at the intensity of about 75% VO2max (18??5～24m／min,gradient of 0°,each motion lasting 50 minutes,twice a day). Detect the content of gastrocnemius MHC mRNA by gastrocnemius reverse transcription polymerase chain reaction,and detect the changes of MHC muscle fiber and its size of cross section area through immunohistochemistry. Meanwhile,apply the electric stimulation to determine the maximal tension of isometric contraction of post-training gastrocnemius.
