Objective: To compare the clinical efficacy and safety of oral administration of Buxue Yimu Pills (BYP, ), ferrous sulfate (FS), and the combination of BYP and FS on gynecological anemia, and investigate the mechanisms using network pharmacology., Methods: A randomized, controlled, multi-center clinical trial was conducted. Totally 150 patients with hemoglobin of 70-110 g/L due to gynecological conditions were recruited and randomized (using the block randomization method) into Buxue Yimu Pills group (24 g/d), oral iron group (FS Tablets, 0.9 g/d), and combined treatment group (BYP, 24 g/d plus FS Tablets, 0.9 g/d), 50 patients in each group. At the enrollment and 4-week treatment, complete blood count, serum iron indexes were evaluated. Adverse events, liver and renal functions, as well as blood coagulation were observed. Network pharmacology was conducted to identify the active ingredients and explore the potential mechanisms of BYP., Results: Ten (20%) and 7 (14%) participants discontinued the therapy due to gastrointestinal symptoms in oral iron and combination treatment groups. All 3 groups showed elevated hemoglobin. The patients in the iron group exhibited typically elevated in serum iron and ferritin and decreased in total iron-binding capacity. No change in iron indexes was observed in BYP group. The patients in the combination treatment group neither showed significant changes in serum ferritin nor total iron-binding capacity. No significant adverse reactions were observed in the BYP group. The network pharmacology identified 27 bioactive compounds and 145 targets of BYP on gynecological anemia. Biological processes and pathways including regulation of inflammation, hormone, angiogenesis and hemostasis, response to decreased oxygen levels, effects on myeloma cell, and response to metal ions were identified., Conclusion: BYP contributes to the practical improvement on gynecological anemia potentially through multi-target mechanisms and optimized iron re-distribution.

Objective: To evaluate the effects of Chinese medicine Dingkun Pill () alone or in combination with Diane-35 on patients with polycystic ovary syndrome (PCOS)., Methods: This is a prospective randomized controlled trial conducted at Peking Union Medical College Hospital Beijing, China, from December 2016 to September 2017. Totally 117 PCOS patients were randomly assigned to the Dingkun Pill group (38 cases), Diane-35 group (40 cases), or combined group (39 cases). Patients in the Dingkun Pill group or Diane-35 group took daily 7 g of oral Dingkun Pill or 1 tablet of oral Diane-35, respectively, for 21 consecutive days followed by 7 drug-free days. And the combined group received a combination of Dingkun Pill and Diane-35. The treatment course was 3 months. Fasting plasma glucose and insulin, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), free fatty acids (FFA) and sex hormones were analyzed, quantitative insulin sensitivity check index (QUICKI) was calculated, and menstruation and acne scores were recorded at baseline and after 3-month treatment., Results: Compared with before treatment, QUICKI decreased significantly in the Dingkun Pill and combined groups after 3-month treatment (P<0.05); TC, LDL-C and FFA decreased significantly in the Dingkun Pill group (P<0.01), LDL-C also decreased obviously in the Diane-35 group (P<0.01), while TC increased significantly in the combined group (P<0.01), TG increased significantly in all groups (P<0.01); total testosterone (TT) and menstruation regularity was improved significantly in the Diane-35 and combined groups (P<0.01); acne scores were improved in all groups (P<0.01). After treatment, TC and FFA in the Dingkun Pill group were significantly lower than the Diane-35 group (P<0.05 or P<0.01); TT was lower and regular menstruation rate was higher in the Diane-35 and combined groups than the Dingkun Pill group (P<0.01), and no differences were observed between Diane-35 group and combined group (P>0.05)., Conclusions: Dingkun Pill showed better effects than Diane-35 in improving insulin sensitivity, lowering TC and FFA. Diane-35 was more efficient in regulating menstruation and lowering androgen than Dingkun Pill. Combination of Dingkun Pill and Diane-35 may be a better choice to regulate menstruation, lower androgens while improve glucose metabolism in PCOS patients.

Objective: To investigate the effect of Shenxiong Huayu capsule on the expression of hippocampal CA1 recombinant protein A (small GTP binding protein A, RHOA) and ROCK-2 (RHO associated protein kinase-2, ROCK-II)., Methods: Clean SD male rats (n=96), divided into three groups with 32 rats for each group, gavage was applied 7 days before modeling until the morning of the day to put to death. The groups included the normal control group (normal saline), global cerebral ischemia model group (normal saline) and Shenxiong Huayu capsule+global cerebral ischemia group (Shenxiong Huayu capsule 0.048 g/kg, was dissolved in 0.5 mL double distilled water, once a day, orally 0.3 mL/100 g). Modified Pulsinelli four-vessel occlusion model was constructed in global cerebral ischemia model and Shenxiong Huayu treatment groups and at 1, 3, 7, 14 d after successful modeling, water maze learning test was applied to evaluate the memory abilities of different groups, histopathological changes in HE staining, expression and protein content of RHOA and ROCK-II in immunohistochemical staining and Western blot was observed., Results: At each time point, escape latency in model group was prolonged (P<0.05) when compared with that in normal control group, and that in Shenxiong Huayu was shorter (P<0.05) than that of model group, but still longer (P<0.05) than that of normal control group. HE staining showed that, compared with the normal group, model hippocampal CA1 reduced gradually from 1 d to 14 d; an increased survival neurons (P<0.05) in Shenxiong Huayu treatment group at each time points was observed, but still less than that in normal group (P<0.05); immunohistochemistry and Western blot analysis demonstrated that the expression of RHOA and ROCK-II in normal control group was not obvious, in model group was decreased after an initial increasing, and that in Shenxiong Huayu treatment group was lower than that of model group (P<0.05), but still higher than that in normal group (P<0.05)., Conclusion: Shenxiong Huayu capsule improve neuronal damage induced by global ischemia, decreased the expression of hippocampal CA1 region of RHOA and ROCK-II.

Objective: To establish a method for HPLC fingerprint determination of the alkaloids in S. flavescens., Method: RP-HPLC, linear gradient elution, LC/MS, etc. were used to determine the fingerprint and identify the main peaks in the HPLC fingerprint., Result: A satisfactory method for HPLC fingerprint determination of the alkaloids in S. flavescens. was established, and 5 peaks in the HPLC fingerprint were identified., Conclusion: The perfect fingerprint can be obtained and the method can be used for quality control of S. flavescens.
