Rules of acupuncture points in the treatment of dysmenorrhea of endometriosis / 国际中医中药杂志

Objective:To summarize the application rules of acupuncture and moxibustion in the clinical trials for dysmenorrhea and endometriosis.Methods:The relevant articles of clinical research on acupuncture and moxibustion for the treatment of dysmenorrhea in endometriosis were retrieved electronically from CNKI, Wanfang, VIP, PubMed and Cochrane Library (Retrieved from database establishment until 31 October 2021). The clinical literatures that met the inclusion criteria were included into the database (Microsoft Office Excel 2019), and the main table and sub-table were established through Microsoft Office Excel 2019. Descriptive statistic analysis was performed by using SPSS 26.0 software. StataSE15 (64-bit) software was used to analyze the correlation between the combinations of acupoints with single acupoint frequency>5.Results:A total of 40 clinical studies were included. Of them, the top 3 acupuncture methods according to the frequency were acupuncture (11 times), moxibustion (11 times), and electro-acupuncture (8 times), the top 3 acupuncture points used according to the frequency were Guan Yuan (34 times), San Yin Jiao (26 times), and Zhong Ji (25 times), the top 3 meridians of the body acupuncture points according to the frequency were Ren Meridian (36 times), Spleen Meridian (32 times), and Stomach Meridian (22 times). According to the correlation analysis, body points of Guan Yuan, San Yin Jiao, Uterus, Qi Hai and Zhong Ji were stronge related.Conclusion:Acupuncture can effectively treat EMT dysmenorrhea with less adverse reactions. The methods are mainly acupuncture, moxibustion and electroacupuncture, mostly local acupoints, intersection acupoints and empirical acupoints.

Dissolution Determination of Tamibarotene Tablet by HPLC / 中国药房

OBJECTIVE:To establish a method for the dissolution determination of Tamibarotene tablet. METHODS:HPLC was performed on the column of Diamonsil C18 with mobile phase of methanol-water-acetic acid(85∶15∶1,V/V/V)at a flow rate of 1.0 ml/min,detection wavelength was 235 nm,column temperature was 25 ℃,and injection volume was 20 μl. The paddle method was used to determine the dissolution,using pH6.8 phosphate buffer dissolution as medium,medium volume was 900 ml,the rotat-ing speed was 50 r/min,taking samples after 60 min. RESULTS:The linear range of tamibarotene was 0.801-2.804 μg/ml (r=0.999 6);RSDs of precision,stability and reproducibility tests were lower than 3%;recovery was 99.58%-100.90%(RSD=0.25%,n=9);the accumulative dissolution rate of 3 batches of samples was 98.25%,96.54%,92.38%(n=6). CONCLUSIONS:The method simple,accurate with high sensitivity and specificity,and suitable for the dissolution determination of Tamibarotene tablet.

Increase of p-P38 and uPA expression in human breast cancer / 基础医学与临床

Objective To study the expression and the significance of phosphorylated P38(p-P38) and uPA in breast cancer tissues.Methods Immunohistochemistry(S-P) was used to test the protein expression of p-P38 and uPA in 60 specimens from 50 patients with breast cancer.Western blotting was adopted to detect the protein expression of p-P38 and uPA in breast cancer cells and uPA protein expression after incubation with SB203580,an specific inhibitor of P38 MAPK blocked P38 MAPK signaling pathway.Results The positive rates of p-P38 protein and uPA protein in breast cancer tissues were 56.7%and 60.0% respectively.The protein expression level of p-P38 and uPA in breast cancer tissues was significantly higher than that in adjacent normal tissues(P

Effects of Yiweining recipe on expressions of metalloproteinase-2 and cyclooxygenase-2 mRNAs in ectopic endometrium of rats with endometriosis / 中西医结合学报

OBJECTIVE: To explore the effects of Yiweining Recipe (YWNR), a compound Chinese herbal medicine, on expressions of metalloproteinase-2 (MMP-2) and cyclooxygenase-2 (COX-2) mRNAs in rats with endometriosis (EM). METHODS: Operational self-transplantation was applied in establishing the rat models. Detection of MMP-2 and COX-2 mRNAs was conducted with hybridization in situ. RESULTS: There were significant differences in the expressions of MMP-2 and COX-2 mRNAs between the untreated group and the high-dose YWNR-treated group. YWNR could reduce the expressions of MMP-2 and COX-2 mRNAs. CONCLUSION: YWNR can treat EM through reducing the positive expressions of MMP-2 and COX-2 mRNAs.
