ABSTRACT
OBJECTIVE@#To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on labor pain.@*METHODS@#A total of 151 primiparas who were vaginal delivery were randomized into a TEAS group (76 cases) and a peridural group (75 cases). In the peridural group, peridural blockage was applied to analgesia. In the TEAS group, TEAS was applied at Hegu (LI 4)，Neiguan (PC 6), Jiaji T~L (EX-B 2) and Ciliao (BL 32), disperse-dense wave (2 Hz/100 Hz), 15-50 mA in current intensity. The analgesic time was from 3 cm to completely opening of cervix. The visual analogue scale (VAS) scores were observed before analgesia, after 30, 60, 120 min of analgesia in the two groups. The time of different stages of labor, usage rate of oxytocin, incidence rate of adverse reaction and amount of postpartum hemorrhage were recorded. The newborn's 1 and 5 min Apgar scores were evaluated.@*RESULTS@#The VAS scores showed a downward trend in the two groups after analgesia (0.05). The usage rate of oxytocin and incidence rate of adverse reaction in the TEAS group were 9.2% (7/76) and 2.6% (2/76), which were lower than 34.7% (26/75) and 18.7% (14/75) in the peridural group (0.05).@*CONCLUSION@#The analgesic effect of TEAS is inferior to peridural blockage, but TEAS could relieve labor pain to the tolerance, shorten the time of active phase on the first stage and second stage of labor and reduce the use of oxytocin, has mild adverse reaction.

<p><b>OBJECTIVE</b>To study the association between cholesteryl ester transfer protein (CETP) gene polymorphism and insulin resistance in type 2 diabetes.</p><p><b>METHODS</b>CETP-TaqIB gene was genotyped with polymerase chain reaction-restriction enzyme fragment polymorphism analysis in 108 patients with type 2 diabetes and in 60 normal controls. Plasma lipids, fasting insulin, insulin sensitivity index and insulin resistance index were determined in 108 patients with type 2 diabetes.</p><p><b>RESULTS</b>The distribution of CETP-TaqIB genotypes and B1B2 allele frequency in the patients with type 2 diabetes were similar to that in general population. High density lipoprotein cholesterol (HDL-C), apolipoprotein A1(apoA1) and insulin sensitivity index (ISI) levels were significantly higher in B2B2 genotype than in B1B1 genotype. Fasting insulin (FINS) and Homeostasis model assessment-insulin resistance (HOMA-IR) levels were significantly lower in B2B2 genotype than in B1B1 genotype. No significant differences in triglyceride (TG), total cholesterol(TC),low density lipoprotein cholesterol (LDL-C), apolipoprotein B (apoB) levels were observed among different CETP-TaqIB genotype groups. By multivariate analysis, the determinants of ISI and HOMA-IR were body mass index (BMI), TC, HDL-C and CETP-TaqIB genotype.</p><p><b>CONCLUSION</b>The CETP-TaqIB genotype is independently associated with insulin resistance and lipid metabolism. It may be an important risk factor of insulin resistance in type 2 diabetes.</p>
