Chronic pelvic inflammatory disease(CPID)is a common chronic inflammatory disease in women,and has a long course and is easy to relapse.Danggui Shaoyao Powder is from Jin Gui Yao Lve(Synopsis of the Golden Chamber),which was a commonly-used formula for the treatment of women's abdominal pain in ancient medical records.It is now often used in the treatment of CPID and has achieved satisfactory therapeutic effect.The article summarizes and analyzes the achievements in the clinical research and experimental study of Danggui Shaoyao Powder in the treatment of CPID over the past 10 years,and invesigates the clinical efficacy of Danggui Shaoyao Powder in the treatment of CPID and its therapeutic mechanism.In the field of clinical studies,Danggui Shaoyao Powder for the treatment of CPID was used by modification,or alone,or in combination with antibiotics and Chinese medicine external treatment,and its combined use was effective on significantly improving the indicators of inflammatory response and immune function,alleviating the clinical signs and symptoms such as pain,and did not increase the incidence of adverse reactions compared with the application of western medicines alone.In the field of experimental studies,Danggui Shaoyao Powder played the therapeutic role in CPID by decreasing the adhesion of endothelial cells,regulating the degradation of extracellular matrix,improving the level of inflammatory factors,and down-regulating the expression of proteins related to the nuclear factor κB(NF-κB)pathway.

Effect on Danggui Shaoyao Powder on mitophagy in rat model of Alzheimer's disease based on PINK1-Parkin pathway / 中国中药杂志

This study investigated the mechanism of Danggui Shaoyao Powder(DSP) against mitophagy in rat model of Alzheimer's disease(AD) induced by streptozotocin(STZ) based on PTEN induced putative kinase 1(PINK1)-Parkin signaling pathway. The AD rat model was established by injecting STZ into the lateral ventricle, and the rats were divided into normal group, model group, DSP low-dose group(12 g·kg~(-1)·d~(-1)), DSP medium-dose group(24 g·kg~(-1)·d~(-1)), and DSP high-dose group(36 g·kg~(-1)·d~(-1)). Morris water maze test was used to detect the learning and memory function of the rats, and transmission electron microscopy and immunofluorescence were employed to detect mitophagy. The protein expression levels of PINK1, Parkin, LC3BⅠ/LC3BⅡ, and p62 were assayed by Western blot. Compared with the normal group, the model group showed a significant decrease in the learning and memory function(P<0.01), reduced protein expression of PINK1 and Parkin(P<0.05), increased protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05), and decreased occurrence of mitophagy(P<0.01). Compared with the model group, the DSP medium-and high-dose groups notably improved the learning and memory ability of AD rats, which mainly manifested as shortened escape latency, leng-thened time in target quadrants and elevated number of crossing the platform(P<0.05 or P<0.01), remarkably activated mitophagy(P<0.05), up-regulated the protein expression of PINK1 and Parkin, and down-regulated the protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05 or P<0.01). These results demonstrated that DSP might promote mitophagy mediated by PINK1-Parkin pathway to remove damaged mitochondria and improve mitochondrial function, thereby exerting a neuroprotective effect.

Effect of Danggui Shaoyao Powder on the Uterine Structure and Estrogen Receptor Expression in Model Rats in Perimenopausal Period / 中国药房

OBJECTIVE:To investigate the effect of Danggui shaoyao powder (DSS) on uterine structure and expressions of estrogen receptorα(ERα),estrogen receptorβ(ERβ)in uterine cavity epithelium and matrix in model rats in perimenopausal peri-od. METHODS:40 female SD rats were randomly divided into sham operation group (normal saline),model group (normal sa-line),DSS low-dose,medium-dose,high-dose groups(1.94,3.87,7.44 g/kg),8 in each group. Except that rats in sham opera-tion group received resection of fat nearby ovaries,rats in other groups received resection of bilateral ovaries to induce models in perimenopausal period. After modeling,rats were intragastrically administrated once a day,for 8 weeks. After administration,wet mass of uterine was weighted. Changes in uterine morphology and structure of rats were observed,expressions levels of ERα and ERβ in uterine cavity epithelium and matrix were determined. RESULTS:Compared with sham operation group,rats in model group showed low columnar in endometrial columnar epithelium,lamina propria layer,muscular layer and serous layer were signifi-cantly atrophied,stromal cells had obvious nuclear condensation. There was marked decrease in uterine wet mass,uterine cavity ar-ea and endometrial thickness as well as the number of uterine glands(P<0.01),and the expression levels of ERαand ERβin uter-ine cavity epithelium and matrix were significantly reduced(P<0.01). Compared with model group,the atrophy degree of endome-trium and lamina propria layer had no significant differences in DSS each dose groups. However,lamina propria layer was rich in glands,and there were significant differences in uterine wet mass,uterine cavity area,endometrial thickness,ERα expression level in uterine cavity epithelium and matrix (P>0.05). However, the number of uterine glands in DSS medium-dose,high-dose groups was significantly increased(P<0.01),and ERβexpres-sion level in uterine cavity epithelium and matrix in DSS high-dose group was significantly increased (P<0.05 or P<0.01). CONCLUSIONS:DSS has not obvious effect on im-proving the symptoms of uterine gland atrophy of model rats in perimenopausal period,but it can increase the number ofuterine glands,and the mechanism may be associated with improving the ERβ expression level in uterine cavity epithelium and ma-trix.

Effects of Danggui Shaoyao Powder on oxytocin-induced in vivo uterine contractions and vasomotor factors of rats / 中草药

Objective: To explore the effects of Danggui Shaoyao Powder (DSP) on in vivo uterine contractions and vasomotor factors of rats, and to investigate the mechanism of DSP for healing primary dysmenorrhea. Methods: Female SD rats were randomly divided into model, Verapamil (100 μg/kg, positive control), low-, mid-, and high-dose DSP (4, 8, and 16 g/kg) groups, and the rats were administered once daily for 7 d. The rats were sc administered with diethylstilbestrol (4 mg/kg) on day 7, on the next day the in vivo uterine contraction of rats was observed before and after oxytocin treatment under anesthesia condition, and the levels of nitric oxide (NO) and endothelin (ET) in uterine homogenate were determined. Results: DSP increased the average muscle tension of uterine contraction of normal rats obverously, but inhibited the oxytocin-induced uterine contraction significantly. The changes of the uterine contraction frequency, amplitude, average muscle tension, and uterine vigour of rats before and after oxytocin processing were significantly inhibited. DSP increased the NO level in the uterine of the experimental animals after oxytocin treatment and reduced the level of ET. The NO/ET ratio increased significantly. Conclusion: DSP could inhibit the in vivo uterine contraction, regulate the vasomotor substances, and improve the uterine blood supplement, resulting in the beneficial effect on treating primary dysmenorrhea.
