Clinical effect of Resina Draconis capsules on primary dysmenorrhoea

Purpose: To examine the effectiveness of Resina Draconis capsules in the treatment of primary dysmenorrhoea. Methods: In total, 324 patients with primary dysmenorrhoea were randomly allocated to three groups based on treatment with capsules containing Resina Draconis, Leonurus japonicus Houtt., or a placebo for 3 months. The patients’ visual analogue scale (VAS) scores and dysmenorrhoea symptoms were evaluated. Results: VAS scores of the Resina Draconis, L. japonicus, and placebo groups decreased from 7.31 ± 1.36, 7.12 ± 1.65, and 7.25 ± 1.47 to 3.35 ± 1.43, 5.27 ± 1.24, and 7.08 ± 2.10, respectively. The change was greatest for the Resina Draconis group (p < 0.01). The incidence of symptoms associated with dysmenorrhoea decreased in all three groups, but the change was greatest for Resina Draconis group (p < 0.01). Overall, Resina Draconis was more effective than L. japonicus (94.40 vs. 72.20 %) (p < 0.05). Conclusion: Resina Draconis capsules are effective in relieving primary dysmenorrhoea and lowering the incidence of symptoms associated with dysmenorrhoea.

Clinical efficacy and safety of edaravone therapy in acute cerebral haemorrhage

Purpose: To evaluate the clinical efficacy and safety of edaravone in the treatment of acute cerebral haemorrhage (ACH). Methods: This study recruited 120 patients who developed ACH. The patients were divided into control and treatment groups with 60 patients per group. The control group underwent conventional treatment and the treatment group also received intravenous edaravone. The volumes of cerebral edema and cerebral hematoma, high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) levels, and Chinese Stroke Scale (CSS) score before and after treatment were compared between the two groups. Results: The respective cerebral edema volumes of the control and treatment groups decreased from 20.99 ± 12.09 and 21.80 ± 12.01 mL on day 0 to 11.23 ± 6.34 and 12.11 ± 5.98 mL at day 7 and 4.69 ± 4.03 and 4.64 ± 3.9 mL on day 14 (P < 0.05). The respective cerebral hematoma volumes of the control and treatment groups decreased from 18.98 ± 12.04 and 18.97 ± 12.07 mL on day 0 to 12.34 ± 6.57 and 11.89 ± 4.01 mL at day 7 and 9.49 ± 3.95 and 9.52 ± 3.96 mL on day 14. Compared with pretreatment, hs-CRP and IL-6 levels and CSS score of the two groups decreased significantly following treatment (p < 0.05); the differences in the cerebral edema and hematoma volumes of the two groups on days 7 and 14 were not significant (p > 0.05). The hs-CRP and IL-6 levels and CSS scores of the treatment group decreased appreciably (p < 0.05), while the incidence of adverse reactions in the treatment and control groups was 16.67 and 13.33 %, respectively, but the difference was not significant (p > 0.05). Conclusion: Edaravone shows remarkable clinical efficacy and safety with no obvious adverse reactions in the treatment of ACH. Therefore, its use is recommended.

Association of follicle stimulating hormone receptor promoter with ovarian response in IVF-ET patients

Background: Poor ovarian response phenomenon has been observed in some of the in vitro fertilization-embryo transfer patients. Some investigations found that follicle stimulating hormone receptor (FSHR) gene plays a role in the process, but no direct evidence shows the correlation between genotypes of FSHR and ovarian response. Objective: Exploring the molecular mechanism behind the mutation of FSHR promoter association with ovarian granulosa cells and poor ovarian response. Materials and Methods: This cross sectional study was performed using 158 women undergoing the controlled short program ovarian stimulation for IVF treatment. The 263 bp DNA fragments before the follicle stimulating hormone (FSH) receptor 5' initiation site were sequenced in the patients under IVF cycle, 70 of which had poor ovarian response and 88 showed normal ovarian responses. Results: With a mutation rate of 40%, 63 in 158 cases showed a 29th site G→A point mutation; among the mutated cases, the mutation rate of the poor ovarian responders was significantly higher than the normal group (60% versus 23.9%; χ2=21.450, p<0.001). Besides, the variability was also obvious in antral follicle count, and ovum pick-ups. The estradiol peak values and the number of mature eggs between the two groups had significant difference. However, there was no obvious variability (t=0.457, p=0.324) in the basic FSH values between the two groups (normal group, 7.2±2.3 U/L; mutation group, 7.1±2.0 U/L). Conclusion: The activity of FSHR promoter is significantly affected by the 29th site G→A mutation that will weaken promoter activity and result in poor response to FSH.
