Primary nephrotic syndrome refers to one of the common glomerular diseases in children.Glucocorticoid is the first choice in the treatment of nephrotic syndrome, and the using cycle is long.Long term application of glucocorticoids can cause side effects, including Cushing′s disease, hypertension, decreased immune function, growth retardation and eye adverse reactions.Among eye adverse reactions, glaucoma and cataract are more common.Glucocorticoid-induced glaucoma and glucocorticoid-induced cataract are often concealed, and children often cannot accurately express their discomforts.At the same time, some clinicians lack the understanding of the adverse reaction, which is easy to cause missed diagnosis and misdiagnosis.Eventually, irreversible visual impairment occurred.Here, the etiology, pathogenesis, clinical diagnosis, and treatment of glucocorticoid-induced glaucoma and glucocorticoid-induced cataract are elaborated, thus aiming to improve clinicians′ understanding of glucocorticoid ophthalmopathy and the level of clinical diagnosis and treatment.

A serum inhibited gene Si1(GenBank acession number:AY050169) was previously cloned and identified by differential expression of genes in U251 cells.For the further study of biological function of Si1, prediction procedure was performed to predict its subcelluar-localization.Relative experiments were carried out at the same time.The expression of EGFP/Si1 recombinant in HeLa cells showed Si1 protein located in nuclear which corroborated the prediction results of PsortⅡ, Proloc, Cello version2, Subnuclear compartments prediction system, NUCLEO and NUCPRED.According to the PredictNLS prediction, twelve different fragments of EGFP/Si1 recombinants were constructed to identify precise NLS regulation sequence.Findings proved that the real NLS regulation sequence was not the same as the software predicted(1 206 bp～1 239 bp on Si1 ORF), but located on 1 395 bp～1 594 bp of Si1.A tumor relatived mutation/EGFP recombinant localization result showed though the mutation site(1 639bp on Si1 ORF) does not located in NLS regulation sequence, it did affect wildtype Si1 protein divert to nuclear and may affect its natural function in cell, perhaps it is the main reason for highly mutation rate of Si1 in tumor.

Background and purpose:In 2016 the National Cancer Institute(NCI)decided stopping to use NCI-60 cell lines for drug screening,suggesting that tumor cell lines were losing their value as a tool for drug discovery and basic research.The reason for NCI-60 cells'retirement'was that the preclinical studies based on traditional cellular and animal models did not obtain the corresponding expected efficacy in clinical trials.Since the major cancer behaviors,such as proliferation and metastasis,are fundamentally altered with long-term culture,the tumor cell lines are not representative of the characteristics of cancer in patients.Currently,scientists hope to create a new cancer model that are derived from fresh patient samples and tagged with details about their clinical past.Our purpose was to create patient-derived breast cancer primary cell lines as new cancer model for drug screening and basic research.Methods:Breast cancer tissues were collected in the Department of Breast Surgery,Affiliated Hospital of Guizhou Medical University.The collection of tumor tissue samples was approved by the Ethics Committee of the Affiliated Hospital of Guizhou Medical University(approval number:2022 ethics No.313),and the collection and use of tumor tissues complied with the Declaration of Helsinki.The primary breast cancer cell lines were isolated from the patient's breast cancer tissues and cultured in BCMI medium.After the cells proliferated,the media were replaced with DEME medium.Cell line STR genotyping was done to determine cell-specific genetic markers and identification.Clone formation assay and transplantation assay were done to analyze the ability of breast cancer primary cell lines to form tumors.Results:We created 6 primary breast cancer cell lines.The 6 primary breast cancer cell lines from the patients were tagged with the definitively clinicopathological features,clinical diagnosis,therapeutic regimens,clinical effectiveness and prognostic outcomes.The STR genotyping assays identified the genetic markers and determined the identities of the 6 primary breast cancer cell lines.Clone formation assays and transplantation assay showed that the proliferative capacities of the patient-derived primary breast cancer cell lines were significantly greater compared with the conventional breast cancer cell lines.Conclusion:We created a panel of 6 patient-derived primary breast cancer cell lines as new cancer model for drug screening and basic research in breast cancer.

【Objective】 To develop a new approach for the preparation of 0.7~0.8 hematocrit concentrated washed red blood cells(RBCs) for fetal anemia in utero transfusion and apply it in clinical. 【Methods】 The erythrocyte suspension and frozen stored erythrocytes within expiry date in Guangzhou Blood Center from March 2020 to February 2021 were taken to prepare concentrated washed RBCs. According to the derivation formula, corresponding weight of RBC preservation solution was added to obtain 0.7~0.8 hematocrit concentrated washed RBCs. Routine blood test data were statistically analyzed by single-sample t test, and P<0.05 was considered statistically significant. Qualified Rh-negative/ O-type 0.7~0.8 hematocrit concentrated RBCs within expiry date were used in clinical intrauterine blood transfusion. 【Results】 The hematocrit of concentrated washing RBCs prepared by the new approach could reach 0.7~0.8. The RBCs count (8.389 ±0.808)×1 0¹²/ L and hemoglobin content(233.730±15.498)g/L were higher while the erythrocyte count (0.732±0.469)×10⁹ /L and platelets count(26.000±26.276)×10⁹/L were lower than the normal values of adults. The mean erythrocyte volume(fL), hemoglobin content(pg) and concentration(g/L )were 88.123±6.359, 30.004±2.809 and 339.980±11.865, respectively, which were normal values of adults. Fetal anemia was significantly improved and the prognosis was good after intrauterine blood transfusion. 【Conclusion】 The 0.7~0.8 hematocrit concentrated washed RBCs prepared by the new approach is consistent with the special blood requirements during fetal anaemia transfusion, meets the clinical treatment standards, and can be applied in clinical.
