Abstract
One of the common side effects of chemotherapy drugs is ovarian failure and uterine dysfunction, which can occur after the administration of doxorubicin and/or cyclophosphamide. In clinics, gonadotropin-releasing hormone agonists (GnRHa) are used to modulate the toxic effect of chemotherapy and intercept infertility with some controversy and limited histological knowledge. This study aimed to evaluate the serological and histological features of protective effects of triptorelin, (GnRHa), on utero-ovarian tissue in the mice treated with cyclophosphamide and/or doxorubicin. Forty-eight female BALB/c mice were randomly divided into 8 groups as follows: Group I: normal saline; Group II: triptorelin; Group III: cyclophosphamide; Group IV: doxorubicin; Group V: cyclophosphamide + doxorubicin; and Groups VI, VII, and VIII: after injection of cyclophosphamide, doxorubicin, or cyclophosphamide + doxorubicin, administration of triptorelin (1 mg/kg; intraperitoneally) for 15 consecutive days, respectively. On the 21st day, the ovaries and uterine horns were dissected and weighed. Then, tissue processing and staining were performed for further histological and stereological studies. Triptorelin treatment in the damaged groups significantly increased the number of primordial and pre-antral follicles and granulosa cells. It decreased the number of atretic follicles compared to cyclophosphamide and/or doxorubicin-treated groups (P < 0.05). Triptorelin also significantly improved the volume of the ovary, cortex, medulla, oocytes in the primordial and antral follicles, uterus, endometrium, myometrium, uterine glands, and endometrial blood vessels in the damaged groups (P < 0.05). Triptorelin treatment prevents the destructive effects of cyclophosphamide and/or doxorubicin on utero-ovarian tissue.

Efficacy of Dan'e Fukang Soft Extract in Moderate Ovarian Hyperstimulation Syndrome for Concurrent Treatment of Blood and Fluid Guided by the "Triple Prevention" Principle. Int J Womens Health 2024; 16:385-394. [PMID: 38463688 PMCID: PMC10924772 DOI: 10.2147/ijwh.s436965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 02/25/2024] [Indexed: 03/12/2024] Open
Abstract
Objective This study aimed to evaluate the therapeutic efficacy and safety of Dan'e Fukang soft extracts in moderate ovarian hyperstimulation syndrome (OHSS) for the simultaneous treatment of blood and fluid, guided by the traditional Chinese medicine principle of "triple prevention". Methods This study conducted a retrospective analysis of clinical data from outpatients who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection embryo transfer (ICSI-ET). A total of 2245 cases were included and divided into a treatment group (1002 cases) and a control group (1243 cases). Patients in the treatment group were administered Dan'e Fukang soft extracts orally in addition to conventional Western medicine. Comparative assessments were made between the two groups on pelvic ascites volume, maximum ovary diameter, dysmenorrhea incidence post-oocyte retrieval, and safety indicators. Results There were no statistically significant differences between the treatment group and the control group in terms of general characteristics or the levels of follicle-stimulating hormone (FSH), luteotropic hormone (LH), estradiol (E2), or progesterone (P) at the time of gonadotropin (Gn) initiation. The groups did not differ significantly when we compared the levels of LH, E2, or P on the day of human chorionic gonadotropin (hCG) injection and during ovarian hyperstimulation protocols (P > 0.05 for all indicators). The differences in the volume of pelvic ascites, the maximum ovarian diameter, and the incidence of dysmenorrhea after oocyte retrieval were statistically significant between the treatment group and the control group (P < 0.05 in both). There were no instances of adverse reactions in either group. Conclusion Based on the traditional Chinese medicine principle of "triple prevention", the use of Dan'e Fukang soft extracts for the simultaneous treatment of blood and fluid in moderate OHSS significantly improved the absorption of pelvic ascites, promoted ovarian recovery, and reduced the incidence of dysmenorrhea after oocyte retrieval.

Abstract
OBJECTIVE In this study, we aimed to determine the impact of the antiangiogenic medications, namely, aflibercept and cabergoline in the prevention and treatment of ovarian hyperstimulation syndrome in a rat model. METHODS A total of 36 female Wistar rats were randomly allocated to one of the five groups, including disease-free and ovarian hyperstimulation syndrome controls: Group no OHSS (control, n=6) received saline only intraperitoneally (i.p.); group just OHSS (ovarian hyperstimulation syndrome only, n=6) received 10 IU pregnant mare serum gonadotropin and 30 IU human chorionic gonadotropin subcutaneously to produce ovarian hyperstimulation syndrome; group cabergoline+OHSS (cabergoline+ovarian hyperstimulation syndrome, n=8) received 100 μg/kg oral cabergoline; group aflibercept (12.5 mg/kg)+OHSS (aflibercept+ovarian hyperstimulation syndrome, n=8) received 12.5 mg/kg i.p. aflibercept; and group aflibercept (25 mg/kg)+OHSS (aflibercept+ovarian hyperstimulation syndrome, n=8) received 25 mg/kg i.p. aflibercept. The groups were compared for ovarian weight, immunohistochemical vascular endothelial growth factor expression, spectrophotometric vascular permeability evaluated with methylene blue solution in peritoneal lavage, and body weight growth. RESULTS Vascular endothelial growth factor immunoexpression was substantially greater in the just OHSS group (22.00±10.20%) than in the aflibercept (12.5 mg/kg)+OHSS (7.87±6.13%) and aflibercept (25 mg/kg)+OHSS (5.63±4.53%) groups (p=0.008 and p=0.005, respectively). Post-hoc tests indicated that cabergoline, 12.5 mg/kg aflibercept, and 25 mg/kg aflibercept decreased vascular permeability compared to the untreated ovarian hyperstimulation syndrome group (p=0.003, p=0.003, and p=0.001, respectively). JOH group had the heaviest ovaries, whereas aflibercept (25 mg/kg)+OHSS group had the lightest. In terms of body weight gain, cabergoline+OHSS group was substantially greater than the aflibercept (12.5 mg/kg)+OHSS and aflibercept (25 mg/kg)+OHSS groups (p=0.006 and p=0.007, respectively). CONCLUSION Aflibercept, an antiangiogenic medication, decreased ovarian hyperstimulation syndrome by lowering the vascular permeability and vascular endothelial growth factor expression.

Abstract
Cell volume regulation (CVR) is a prerequisite for animal cells to survive and fulfill their functions. CVR dysfunction is essentially involved in the induction of cell death. In fact, sustained normotonic cell swelling and shrinkage are associated with necrosis and apoptosis, and thus called the necrotic volume increase (NVI) and the apoptotic volume decrease (AVD), respectively. Since a number of ubiquitously expressed ion channels are involved in the CVR processes, these volume-regulatory ion channels are also implicated in the NVI and AVD events. In Part 1 and Part 2 of this series of review articles, we described the roles of swelling-activated anion channels called VSOR or VRAC and acid-activated anion channels called ASOR or PAC in CVR and cell death processes. Here, Part 3 focuses on therein roles of Ca2+-permeable non-selective TRPM2 and TRPM7 cation channels activated by stress. First, we summarize their phenotypic properties and molecular structure. Second, we describe their roles in CVR. Since cell death induction is tightly coupled to dysfunction of CVR, third, we focus on their participation in the induction of or protection against cell death under oxidative, acidotoxic, excitotoxic, and ischemic conditions. In this regard, we pay attention to the sensitivity of TRPM2 and TRPM7 to a variety of stress as well as to their capability to physicall and functionally interact with other volume-related channels and membrane enzymes. Also, we summarize a large number of reports hitherto published in which TRPM2 and TRPM7 channels are shown to be involved in cell death associated with a variety of diseases or disorders, in some cases as double-edged swords. Lastly, we attempt to describe how TRPM2 and TRPM7 are organized in the ionic mechanisms leading to cell death induction and protection.

Abstract
Angiogenesis is strongly associated with ovarian hyperstimulation syndrome (OHSS) progression. Early growth response protein 1 (EGR1) plays an important role in angiogenesis. This study aimed to investigate the function and mechanism of EGR1 involved in OHSS progression. RNA-sequencing was used to identify differentially expressed genes. In vitro OHSS cell model was induced by treating KGN cells with human chorionic gonadotropin (hCG). In vivo OHSS model was established in mice. The expression levels of EGR1, SOX1, and VEGF were determined by Quantitative Real-Time polymerase chain reaction (qRT-PCR), Western blot, immunofluorescence staining, and immunochemistry assay. The content of VEGF in the culture medium of human granulosa-like tumor cell line (KGN) cells was accessed by the ELISA assay. The regulatory effect of EGR1 on SRY-box transcription factor 9 (SOX9) was addressed by luciferase reporter assay and chromatin immunoprecipitation. The ERG1 and SOX9 levels were significantly upregulated in granulosa cells from OHSS patients and there was a positive association between EGR1 and SOX9 expression. In the ovarian tissues of OHSS mice, the levels of EGR1 and SOX9 were also remarkedly increased. Treatment with hCG elevated the levels of vascular endothelial growth factor (VEGF), EGR1, and SOX9 in KGN cells. Silencing of EGR1 reversed the promoting effect of hCG on VEGF and SOX9 expression in KGN cells. EGR1 transcriptionally regulated SOX9 expression through binding to its promoter. In addition, administration of dopamine decreased hCG-induced VEGF in KGN cells and ameliorated the progression of OHSS in mice, which were companied with decreased EGR1 and SOX9 expression. EGR1 has a promoting effect on OHSS progression and dopamine protects against OHSS through suppression of EGR1/SOX9 cascade. Our findings may provide new targets for the treatment of OHSS.

Abstract
Objective: Ovarian hyperstimulation syndrome is an iatrogenic condition that occurs in the treatment of infertility. There is no specific treatment available for OHSS. Cabergoline is a dopamine receptor 2 agonist and VEGF-VEGF2 receptor antagonist . Recently, cabergoline has been widely used to prevent the development of OHSS and reduce its severity Serotonin is known as a neurotransmitter and thought to have a role in the mechanism of angiogenesis and in signaling in endothelial cells. Serotonin is said to have similar effects to VEGF . Ondansetron is Selective Serotonin (5-HT3) Receptor Antagonist . It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. In the clinical practice today, there is no choice other than cabergoline, to prevent occurrence and reduce severity of OHSS, and sometimes its effects are limited. Methods: In our study, we compared the effect of cabergoline and ondansetron. 32 immature rats were used and the OHSS model was created. Parameters such as hematocrit value , ovarian size, the number of follicles in the ovary, endometrial capillary congestion and thickness values were evaluated and compared. Results: As a result, in our study, it was seen that ondansetron was effective on OHSS in many parameters. It is thought to be as effective as cabergoline. When we look at the literature, this is the first study in which ondansetron was evaluated for this purpose. It would be good to show this effect of ondansetron with other studies.

Abstract
AIMS Ginkgo biloba extract (EGb) has been widely applied in the treatment of cerebrovascular and neurological diseases. However, the effect of EGb761 on ovarian hyperstimulation syndrome (OHSS), a vascular disorder and life-threatening complication of in vitro fertilization and intracytoplasmic sperm injection therapy (IVF/ICSI), has not been evaluated. MATERIALS AND METHODS Forty female Wistar rats aged 22-days old (D22) were divided into eight groups: Control rats received intraperitoneal injection of saline for five consecutive days (D22-D26); OHSS model group received 10 IU equine chorionic gonadotropin (eCG) for four consecutive days (D22-D25) and 30 IU of human chorionic gonadotropin (hCG) on the 5th day (D26); Prophylactic treatment group received three doses of EGb761 (50, 100, and 200 mg/kg/day) 1 h before injection of eCG (hCG) for seven consecutive days; Therapeutic treatment group received three doses of EGb761 (50, 100, and 200 mg/kg/day) 48 h after injection of eCG (hCG) for seven consecutive days. RESULTS All three doses of EGb761 therapeutic medication significantly reduced ovarian mass index of OHSS model rats (p ≤ .01). Furthermore, therapeutic treatment group exhibited improved vascular permeability, decreased estradiol and progesterone levels, lower corpus luteum, and higher follicle numbers compared with the OHSS model. Elevated protein expression of vascular endothelial growth factor (VEGF) and VEGF receptor (VEGFR) in both ovary and kidney of the OHSS model was restrained by EGb761 therapeutic treatment. CONCLUSIONS EGb761 therapeutic medication decreases vascular permeability in OHSS rat model by inhibiting VEGF and VEGFR expression, which may contribute to the treatment of OHSS.
