Risk Prediction Model for Surgical Treatment of Ruptured Corpus Luteum in the Ovary

Objective: To explore the related factors of surgical treatment of patients with corpus luteum rupture and establish a risk prediction model of surgical treatment of corpus luteum rupture. Methods: 222 patients with corpus luteum rupture treated in Jingzhou First People’s Hospital from January 2015 to March 2022 were analyzed retrospectively, including 45 cases of surgery and 177 cases of conservative treatment. The training set and validation set were randomly assigned according to 7:3. We collected the basic information, laboratory and ultrasonic examination data of 222 patients. Logistic regression analysis was used to determine the independent risk factors and combined predictors of surgical treatment of corpus luteum rupture. The risk prediction model was established and the nomogram was drawn. The discrimination and calibration of the prediction model were verified and evaluated by receiver operating characteristic (ROC) curve, calibration curve and Hosmer-Lemeshow goodness of fit test;Decision curve analysis (DCA) was used to evaluate the clinical effectiveness of the prediction model. Results: Univariate logistic regression showed that whole abdominal pain (OR: 2.314, 95% CI: 1.090 - 4.912), abdominal muscle tension (OR: 2.379, 95% CI: 1.112 - 5.089), adnexal mass ≥ 4 cm (OR: 3.926, 95% CI: 1.771 - 8.266), hemoglobin Conclusion: The nomogram prediction model containing three predictive variables (hemoglobin, depth of pelvic effusion under ultrasound and cervical lifting pain) can be used to predict the risk of surgical treatment in patients with corpus luteum rupture.

Comparative Study of the Therapeutic Effects of Two Corpus Luteum Support Regimens on Patients with Frozen Embryo Transfer

Aim: To investigate the efficacy of two corpus luteum support programs in patients with frozen embryo transfer (FET). Methods: A retrospective analysis of the complete clinical data of 340 patients undergoing in vitro fertilization embryo transfer in the Department of Reproductive Medicine, Jingzhou Central Hospital from September 2016 to July 2018. These patients were divided into group A and B according to the luteal support program. We compared the clinical outcomes of the two corpus luteum preparations by comparing the laboratory parameters of the two groups of patients with clinical pregnancy indicators. Results: We found there was no significant difference in the results of general conditions in the two groups of patients, such as infertility age and duration, body mass index (BMI), basal follicle stimulating hormone (FSH), basal luteinizing hormone (LH), basal estrogen (E2) levels, the endometrial thickness, the number of transplanted high-quality embryos on the day of transplantation and so on (P > 0.05). We found that the implantation rate (32.55%), biochemical pregnancy rate (53.57%), and clinical pregnancy rate (51.78%) in group B were significantly higher than those in group A (25.26%, 35.11%, and 34.66%, respectively) (P 0.05). Conclusion: We conclude that patients who are scheduled for frozen embryo transfer use progesterone vaginal sustained release capsules combined with luteal progesterone luteal support, have improved clinical pregnancy rates.

Observations on the Diagnostic Effects of CT Examination(Enhanced Scan)on Hemorrhage Corpus Luteum Cyst

Objective:To investigate the diagnostic effects of enhanced CT scan on hemorrhage corpus luteum cyst(HCLC).Methods:The clinical data of 24 patients with hemorrhage corpus luteum cyst diagnosed by surgery and pathology in our hospital were collected.All patients received enhanced CT scan to evaluate the diagnostic value of CT.Results:The average diameter of the cysts in this group of patients was 5.1cm by CT.Further detection of the ruptured cyst wall showed that there was a liquid lowdensity shadow.Some of the cysts were accompanied by signs of increased density,indicating the presence of blood clots;all patients received surgical treatment.Intraoperative ultrasound examination of the cysts had an average diameter of 5.2cm and a wall of 0.2~0.4mm.Among them,19 cases of cysts contained"coffee-colored"liquid with varying degrees of blood clots,and 5 cases had no blood clots in the cysts but there were a lot of blood clots beside the cysts.Conclusion:The application of enhanced CT scan in patients with hemorrhage corpus luteum cyst is of great value.It can provide accurate data reference for clinical treatment and is worthy of promoting its clinical application.

Ultrasonographic Monitoring of Previous Pregnant Corpus Luteum in Postpartum Cow

Sequential ultrasonograms of both ovaries were taken once a day in six postpartum Jersey cows with B-mode Ultrasound Scanner and the concentrations of progesterone in peripheral circulation of the cows were measured by radioimmunoassay (RIA). The whole texture of the previous pregnant corpus luteum was clearly identified during the process of its regressing. The ppCL could be identified for a mean of 17±12.96 days with a range of 4 to 42 days. There were no significant correlation between the time that the ppCL could be identified and both the times to the first postpartum ovulation and the peripheral progesterone concentration.

Purification and Properties of Cold-active Metalloprotease from Curtobacterium luteum and Effect of Culture Conditions on Production

Curtobacterium luteum, a gram-positive psychrotrophic bacterium, secreting an extracellular protease was isolated from the soil of Gangotri glacier, Western Himalaya. The maximum enzyme production was achieved when isolate was grown in a pH-neutral medium containing skim milk at 15oC over 120 hour. The metal ions such as Zn2+ and Cr2+ enhanced enzyme production. The specific activity of purified enzyme was 8090 u/mg after 34.1 fold purification. The 115 kD enzyme was a metalloprotease (activity inhibited by EDTA and EGTA) and showed maximum activity at 20oC and pH 7. The enzyme was active over a broad pH range and retained 84% of its original activity between pH 6–8. There was no loss in enzyme activity when exposed for 3 hours at 4oC-20oC. However, lost 65% of activity at 30oC, and was almost inactivated at 50oC, but was resistant to repeated freezing and thawing. The enzyme activity was stimulated by manganese ions; however, it was inactivated by copper ions.

氧化应激对母畜卵巢功能影响的研究进展

卵巢是母畜生殖系统的重要组成部分,其功能受多种因素的调控,其中氧化应激作为一种重要的细胞生物学过程,被发现对卵巢功能产生深远影响。卵巢内氧化与抗氧化物的平衡对维持卵巢功能意义重大,卵巢内活性氧(reactive oxygen species,ROS)参与卵母细胞生长、减数分裂、排卵和其他生理过程的调节,ROS堆积可导致卵巢功能紊乱,影响优势卵泡形成,对卵母细胞成熟、受精以及随后的胚胎植入和发育均有影响。本文针对氧化应激对母畜卵巢功能的影响,进一步探究了氧化应激对母畜卵母细胞、颗粒细胞、卵泡膜细胞以及黄体的影响,深入了解其机制有助于揭示卵巢生理和病理的内在联系,为相关疾病的预防和治疗提供新的思路。

Expression of steroidogenic acute regulatory protein and its regulation by interferon-gamma in rat corpus luteum

The steroidogenic acute regulatory protein (StAR) is the key regulatory protein of steroidogenesis. De novo synthesis of StAR protein is required for intramitochondrial translocation of cholesterol to the cytochrome P450 side chain cleavage enzyme which is located on the matrix side of the inner mitochondrial membrane. This is the rate-limiting step of steroid biosynthesis. Using in situ hybridization and immunohistochemistry we studied StAR expression in various stages of the corpora luteal and its regulation by interferon-gamma (IFNγ) in the adult pseudopregnant rat. The results indicated that expression of StAR in the corpora luteal was correlated with progesteron production and IFNγ was capable of inhibiting its expression.

Temporal and spatial expression of MMP-2,-9,-14 and their inhibitors TIMP-1,-2,-3 in the corpus luteum of the cycling rhesus monkey

The corpus luteum(CL)is a transient endocrine organ that secretes progesterone to support early pregnancy.If implantation is unsuccessful,luteolysis is initiated.Extensive tissue re-modeling occurs during CL formation and luteolysis.In this study,we have studied the possible in-volvement of MMP-2,-9,-14,and their inhibitors,TIMP-1,-2,-3 in the CL of cycling rhesus monkey at various stages by in situ hybridization,immunohistochemistry and microscopic assessment.The re-sults showed that the MMP-2 mRNA and protein were mainly expressed in the endothelial cells at the early and middle stages of the CL development,while their expressions were observed in the luteal cells at the late stage during luteal regression.MMP-9 protein was detected in the CL at the early and middle stages,and obviously increased at the late stage.The expressions of MMP-14 and TIMP-1 mRNA were high at the early and late stages,and low at the middle stage.TIMP-2 mRNA was high throughout all the stages,the highest level could be observed at the late stage.The TIMP-3 produc-tion was detected throughout all the stages,but obviously declined during CL regression.MMP-9,-14 and TIMP-1,-2,-3 were mainly localized in the cytoplasm of the steroidogenic cells.The results suggest that the MMP/TIMP system is involved in regulation of CL development in the primate,and the coordinated expression of MMP-2,-14 and TIMP-1,-3 may have a potential role in the CL forma-tion and the functional maintaining,while the interaction of MMP-2,-9,-14 and TIMP-1,-2,-3 might also play a role in CL regression at the late stage of CL development in the primate.

卵巢妊娠破裂三例诊疗体会

卵巢妊娠临床发病率低,一旦破裂患者预后较差。卵巢妊娠大多数在妊娠早期发生破裂,导致腹腔内大量出血,甚至休克。卵巢妊娠破裂术前往往误诊为输卵管妊娠破裂或卵巢黄体破裂,术中经仔细探查方可明确诊断,因此卵巢妊娠的早期诊断和治疗至关重要。本文报道3例卵巢妊娠,其中2例术前出现失血性休克表现,1例表现为腹痛加剧,均行急症手术治疗,术中探查均确诊为卵巢妊娠破裂。卵巢妊娠的治疗包括药物杀胚治疗和手术治疗,一旦发生破裂需行急症手术治疗。临床上对于异位妊娠患者均应考虑到卵巢妊娠可能,做到早诊断、早治疗,避免严重并发症的发生。

Expression and regulation of metalloproteinases-2,-9 and tissue inhibitors of metallo-proteinases in rat corpus luteum

The expression and regulation of metallopro-teinases-2, -9 (MMP-2, -9) and their tissue inhibitors TIMP-1, -2, -3 mRNA were studied in this experiment. In the PMSG-hCG primed pseudopregnant rat, MMP-2, -9 mRNA levels were the highest at Day 1, decreased from Day 4, and reached the minimal level at Day 8, then increased at Day 14; no significant changes were observed in TIMP-2 mRNA expression from Day 1 to Day 14; TIMP-3 mRNA expression was the lowest at Day 1, increased from Day 4, reached the maximal level at Day 8, and persisted to Day 14. TNF-α could significantly increase the expression of MMP-2, -9 and TIMP-1 mRNA in the in vitro perfused pseudopregnant CL, and decrease the expression of TIMP-3 mRNA, but had no effect on TIMP-2 mRNA expression. The results indicate that MMP-2, -9 and TIMP-1, -2, -3 might be involved in the regulation of CL function and maintenance of CL structure via their coordinated gene expression. TNF-a could inhibit luteal regression via increasing MMP-2, -9 and TIMP-1 mRNA

Expression of gelatinases and tissue inhibitors of metallo-proteinases in the rhesus monkey(Macaca mulatta) corpus luteum

Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are believed to play important roles in the formation and regression of corpus luteum (CL). This study is to investigate the expression of gelatinases (MMP-2, -9) and TIMPs in the rhesus monkey CL in both early and late luteal phases and during the early stages of pregnancy. Ovaries were collected from regularly cycling rhesus monkey at D5 and D15 following ovulation and at D12, D18 and D26 of pregnancy. In situ hybridization revealed that in the CL MMP-2 niRNA was expressed during both formation and regression, while MMP-9 mRNA was mainly localized in the late luteal phase. Reduction of MMP-2, -9 transcripts in the CL was observed during pregnancy. MMP-2 mRNA in the CL reduced to an undetectable level at D26 of pregnancy. TIMP-1 mRNA was highly expressed in the CL in both early and late luteal phases and persisted throughout the early stages of pregnancy. Strong signal for TIMP-2 mRNA was also detected in both luteal phases, and the
