Clinical research on acupoint catgut implantation in the prevention and treatment of postpartum pain of uterine contraction with qi and blood deficiency / 中国针灸

<p><b>OBJECTIVE</b>To observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.</p><p><b>METHODS</b>One hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.</p><p><b>RESULTS</b>VAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).</p><p><b>CONCLUSION</b>The intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.</p>

(1)H-MRS study of auditory cortex in patients with presbycusis / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study the metabolic changes of auditory cortex in patients with presbycusis by using proton magnetic resonance spectroscopy ((1)H-MRS).</p><p><b>METHODS</b>Ten normal hearing volunteers (youth group), 10 normal hearing of elderly (aged group) and 8 patients with presbycusis (presbycusis group) were checked with proton magnetic resonance spectroscopy. N-acetylaspartic acid (NAA), creatine (Cr), choline (Cho), γ-aminobutyric acid (GABA), glutamic acid (Glu) compound were measured. The differences between the groups were semi-quantitatively analyzed.</p><p><b>RESULTS</b>When compared with youth group, reduced NAA/Cr, increased Cho/Cr were found in the aged group and presbycusis group (P < 0.05). GABA/Cr ratio and Glu/Cr ratio were significant difference between presbycusis group and youth group (P < 0.05). There were no significant difference in the GABA/Cr and Glu/Cr ratios in the bilateral auditory cortex between the youth group and the aged group (P > 0.05). When compared with aged group, the metabolic changes of auditory cortex in patients with presbycusis were remarkable (P < 0.05).</p><p><b>CONCLUSIONS</b>(1)H-MRS is a noninvasive technique that can provide useful information concerning the metabolic changes of auditory cortex in human. In comparison to the aged group and the youth group, the changes of NAA, GABA, Cho and Glu is found in auditory cortex in patients with presbycusis.</p>
