Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P ＜ 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P＞0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P＜0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P ＜ 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.

AIM: To observe the effect of tranilast on experimental COPD rats in terms of airway remodeling. METHODS: Forty eight SD rats were divided into two groups in random: untreated model group, tranilast-treated group. Another eight rats were selected as control group. The COPD rat model was established by passive smoking and intratracheal instillation of lipopolysaccharide (LPS) and then treated with sterile saline or tranilast (400 mg?kg~ -1 ?d~ -1 ) respectively. Eight rats in each group were killed in 7th, 14th, 28th day after the beginning of proceeding. Bronchoalveolar lavage fluid (BALF) was collected, and the total and differential cells were counted. The distribution and the ratio of type I to type III collagen in the lung tissue were determined using a sirius red polarizing microscopy morphometry method. Lung tissues were observed by hemotoxylin and eosin stain, then the image analysis were made. RESULTS: The total cells and the AM ratio in BALF of tranilast-treated group significantly decreased in comparison with those in model group (P

Objective To investigate the clinical value of vaginal myomectomy. Methods From March 2005 to May 2008,78 women with abnormal uterine bleeding were diagnosed with submucous myoma by hysteroscopy combined with ultrasonography. All the myomas were located in the lower uterine segment,and the diameter of the tumor ranged from 30 mm to 63 mm. The patients were divided into two groups to underwent vaginal myomectomy (vaginal group,36 cases) or abdominal electrotomy (open group,42 cases). The operation time,intraoperative blood loss,postoperative hospital stay and recovery of the two groups were compared. Results The vaginal operation was accomplished in all of the 36 cases. Compared with the open group,the vaginal group had significantly shorter operation time [(64.7?10.4) min vs (71.1?11.3) min,t=-2.599,P=0.011],less intraoperative blood loss [(200.0?38.4) ml vs (253.6?47.6) ml,t=-5.412,P=0.000],quicker recovery of bowel movement [(18.5?4.3) h vs (30.9?4.7) h,t=-12.078,P=0.000],and shorter postoperative hospital stay [(4.9?1.2) d vs (7.0?1.3) d,t=-7.368,P=0.000]. Follow-up was available in all of the 78 cases for 3 to 40 months (mean,28 months),during which no relapse occurred,and no statistical differences in pregnancy rate between the two groups was revealed [2.8% (1/36) vs 4.8% (2/42),?2=0.000,P=1.000]. The operation satisfaction rates in both of the two groups were up to 100%. Conclusions Vaginal myomectomy has advantages in less hemorrhage,fast recovery,short postoperative hospital stay,and low complication rate. For the tumors located in the lower uterine segment or those larger than 30 mm in diameter,vaginal myomectomy is an alternative to hysteroscopic electrotomy.
