Castleman's disease is a rare disorder of the lymphoid system characterized by noncancerous growths that may develop in lymph node tissues throughout the body. The incidence of this disease has been increasing in recent years. Because of the difficulty of diagnosis and high-misdiagnosis, more and more clinicians have paid close attention to this disease. By the clinical work, and with the help of related reports, the preliminary summary of this disease is made.

Objective To study the clinical efficacy of superselective uterine arterioembolization in treating uterine myoma. Methods From February to August 2000, 28 cases of uterine myomas were undergone bilateral arterioembolization of tumor feeding vessels. Results The successful rate of embolization catheterization reached 100%.B-mode ultrasound examination revealed the following during 1～6 months after the procedure, with an average shrinkage of 25% in volume for all cases in the first month follow up,complete disappearance of tumor in 8 cases and with an average shrinkage of 68% volumetrically for the other 20 cases, together with conspicuous decrease in volume of menstruation.Conclusions Interventional treatment for uterine myoma is definite effectilve especilally in submucosal uterine myoma.

Objective:To explore the expression of homologous recombination repair (HRR) deficiency related genes in endometrial cancer and their relationship with clinical pathological features and immune infiltration.Methods:A total of 53 patients with endometrial cancer (endometrial cancer group) who underwent surgical treatment at the Affiliated People′s Hospital of Shandong First Medical University from June 2018 to June 2020 were selected as the study subjects. Clinical data of the patients were retrospectively analyzed, and 50 healthy women who underwent physical examinations were selected as the control group. Clinical and pathological characteristics of 53 patients with endometrial cancer were collected, and real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was performed Methods The mRNA expressions of human breast cancer susceptibility gene 1 (BRCA1), tumor suppressor gene homologous loss phosphatase tensin gene (PTEN) on chromosome 10 in the peripheral blood of the subjects were detected, and the proportions of CD 4+ T cell subsets in peripheral blood monocytes were detected by flow cytometry; Pearson analysis of the correlation between peripheral blood BRCA1, PTEN mRNA expression and various subsets of CD 4+ T cell; Analysis of prognostic factors for endometrial cancer using COX risk regression model. Results:The peripheral blood BRCA1 and PTEN mRNA expression levels in patients with endometrial cancer were higher than those in the healthy control group: 2.87 ± 0.65 vs. 1.02 ± 0.13, 3.25 ± 0.74 vs. 1.01 ± 0.20, and the differences were statistically significant ( P<0.01). The proportion of peripheral blood helper T cell-2 (Th2), helper T cell-17 (Th17), regulatory T cell (Treg) and helper T cell-22 (Th22) in patients with endometrial cancer was significantly higher than that in the healthy control group: (10.72 ± 1.33)% vs. (5.43 ± 0.80)%, (9.78 ± 0.80)% vs. (3.31 ± 0.62)%, (10.81 ± 1.29)% vs. (5.74 ± 0.69)%, (6.09 ± 0.70)% vs. (3.09 ± 0.73)%, and the proportion of helper T cell-1 (Th1) was significantly lower than that in the healthy control group: (5.54 ± 0.90)% vs. (13.07 ± 2.55)%, the difference was statistically significant ( P<0.01). The peripheral blood BRCA1 and PTEN mRNA expression levels were significantly higher in patients with muscle infiltration depth ≥1/2, histological grade G 2 to G 3, lymph node metastasis, and International Federation of Obstetrics and Gynecology (FIGO) stage Ⅲ to Ⅳ than in patients with muscle infiltration depth<1/2, histological grade G 1, no lymph node metastasis, and FIGO stage Ⅰ to Ⅱ, with statistical significance ( P<0.01 or<0.05). Peripheral blood BRCA1 and PTEN mRNA were significantly positively correlated with Th2, Th17, Treg and Th22 ratios ( P<0.01), and negatively correlated with Th1 ratios ( P<0.01). COX risk regression analysis showed that histological grading, FIGO staging, depth of muscle infiltration, peripheral blood BRCA1 and PTEN mRNA expression with lymph node metastasis were all independent prognostic factors for endometrial cancer ( P<0.01 or<0.05). Conclusions:HRR deficiency related genes BRCA1 and PTEN mRNA exhibit high levels in patients with endometrial cancer, and are closely related to muscle infiltration depth, histological grading, lymph node metastasis, and FIGO staging. They can also affect the immune microenvironment of endometrial cancer patients, thereby affecting disease progression and prognosis.
