ABSTRACT
Objective:To observe the effect of acupuncture on gastric motility, plasma motilin and serum gastrin in patients with diabetic gastroparesis (DGP) and evaluate its clinical efficacy. Methods:A total of 100 eligible cases were randomly allocated into an acupuncture group (n=50) and a control group (n=50). Patients in the acupuncture group were treated by needling Zhongwan (CV 12), Zusanli (ST 36) and Neiguan (PC 6), whereas patients in the control group were treated with oral administration of Domperidone. The clinical efficacies of the two groups were compared; and changes in gastric motility, plasma motilin and serum gastrin in both groups were observed before and after treatment. Results:After treatment, the symptom scores, gastric motility and contents of plasma motilin and serum gastrin were significantly improved in both groups (P Conclusion:Acupuncture is effective for DGP and can reduce the levels of plasma motilin and serum gastrin.
ABSTRACT
Objective To establish a real -time quantitative PCR ( RT-PCR) assay for detecting serum miR -122, miR-22, and evaluate the clinical significance of miR -122 and miR-22 in patients with chronic hepatitis B ( CHB) by using of this assay .Meth-ods The mature miRNAs were reversely transcripted by using of stem -loop primers .SYBR GreenⅠquantitative real-time PCR ( qRT-PCR) was used for quantification of the miRNAs .The sensitivity of this assay was evaluated by using of the 10-fold-diluted miRNA-122 cDNA standards and the specificity was verified by using of melting curve assay .The accuracy was assessed by intra -assay coeffi-cient of variation (CV) of threshold cycle (Ct value), which were calculated from a 20-times-repeat detection of the miR -122 cDNA (2 ×105 , 2 ×106 , 2 ×107 copies/μl) standards.Using the established qRT -PCR assay, we detected the expression of serum miR -122 and miR-22 in the patients with CHB and healthy controls .Results The qRT-PCR assay exhibited good performances in the linear range, sensitivity and reproducibility while detecting miR -122 and miR-22.The relative level of miR -122 and miR-22 was 17.88 vs 5.35 in the CHB patients and 1.80 vs 1.67 in the controls (P=0.000).Conclusion Using of stem-loop primers, we established a qRT-PCR assay for detection of serum miR -122 and miR-22.Serum miR-122 and miR-22 increased significantly in the CHB pa-tients.
