Abstract
AIM: To evaluate the efficacy and safety of autologous platelet-rich fibrin (PRF) for the treatment of infertility with intrauterine adhesions. METHODS Forty patients who suffered from infertility with intrauterine adhesions (IUAs) were enrolled in this prospective trial from October 2018 to December 2019. They were randomly divided into a PRF group and a control group. Both groups underwent transcervical resection of adhesions (TCRA) during the follicular phase. PRF group: PRF prepared from autologous venous blood was placed in the uterine cavity after TCRA and after the first menstrual re-fluid; control group: no PRF insertion. After the second menstrual re-fluid, both groups underwent hysteroscopy to reevaluate adhesion severity. Pregnancy rate, intrauterine adhesion score, menstrual volume and duration, and endometrial thickness were assessed and adverse events were recorded. RESULTS (1) PRF group pregnancy rate was significantly higher than the control group (55.0% vs. 20.0%). Mean follow-up time was (17.63 ± 2.33) months. All patients fell pregnant naturally. Four (PRF) and one (control) patients delivered live births without placental complications. (2) Intrauterine adhesion scores decreased compared with treatment-before. (3) In the pictorial blood loss assessment chart, score and menstrual duration during the 3rd menstrual cycle showed significant improvements for both groups. (4) Endometrial thickness also showed an increasing trend, and subendometrial bloodflow improved. (5) No treatment-related serious adverse events were noted. CONCLUSION Placing PRF into the uterine cavity of infertility patients with IUAs following TCRA is a safe and effective therapeutic method.

Abstract
Dysfunctional uterine bleeding is menstrual bleeding in abnormal volume, duration, or time, and it is a common problem in women. A wide range of drug therapies, with varying efficacy, is available for women with dysfunctional uterine bleeding. The use of herbal and traditional medicine is one of the ways to treat this disease, which has fewer side effects than chemical drugs. On the other hand, these medicines have less effect on treatment than chemical drugs. Therefore, increasing their effectiveness in the treatment of diseases has always been important. For this purpose, in this study, a comparison was done between direct use and PLGA nanocapsules containing Tiaojing Zhixue, in the treatment of dysfunctional uterine bleeding. First, PLGA nanocapsules containing Tiaojing Zhixue were synthesized by the electrospray technique. Then 80 women with dysfunctional uterine bleeding were treated with this medicine. These people were divided into two groups of 40 people. The first group was treated with 20mg of Tiaojing Zhixue and the other group was treated with PLGA nanocapsules containing Tiaojing Zhixue for eight months. The duration and frequency of bleeding from one month before the start of treatment and during the eight months after the start of treatment (second, fourth, and eighth month) were assessed in two groups. The two groups were homogeneous in terms of mean frequency of bleeding and mean duration of bleeding before starting treatment. The positive response in the PLGA nanocapsules treatment group (75%) was higher than the direct use drug treatment group (42.5%) (P < 0.01). The rate of side effects was the same in each group. Due to the effectiveness of PLGA nanocapsules in the treatment of dysfunctional uterine bleeding and the lack of side effects, it can be considered as an alternative medicine for the treatment of this disorder.
