The aim of this study was to analyse the risk factors of pregnancy loss of patients with recurrent spontaneous abortion (RSA) and develop a scoring system to predict RSA. Clinical data of 242 cases, with RSA who were treated at Fujian Provincial Maternity and Children's Hospital, were selected. The factors of pregnancy loss for RSA patients were evaluated by univariate and multivariate analyses. There were 242 RSA patients, of whom 34 (14.0%) developed pregnancy loss. A multivariate analysis showed the following adverse risk factors for RSA: antinuclear antibody spectrum, protein s deficiency and antiphospholipid antibodies. The pregnancy loss rates of antinuclear antibody spectrum group, protein S deficiency group and antiphospholipid antibodies group were 25.0%, 22.5% and 19.4%, respectively. Each of these factors contributed 1 point to the risk score. The pregnancy loss rates were 6.3%, 24.6%, 50% for the low-, intermediate- and high-risk categories, respectively ( < .001). The area under the receiver operating characteristic curve for the score of RSA was .733. Our findings suggest that this validated and simple scoring system could accurately predict the risk of pregnancy loss of RSA patients. The score might be helpful in the selection of risk-adapted interventions to decrease the incidence. Impact Statement The live birth rate increases to 80%-90% after anticoagulant and/or immunosuppressive treatment in patients with RSA. However, there is still a high rate of re-abortion even after active treatment. Antinuclear antibody spectrum, protein s deficiency and antiphospholipid antibodies were independent risk factors for pregnancy loss. A novel predictive model based on these factors was then established and validated. The newly developed score might be helpful in the selection of risk-adapted interventions to decrease the incidence. For patients in the intermediate-risk and high-risk groups, we should conduct more targeted studies and formulate corresponding therapies to improve the success rate of treatment.

LZAP promotes the proliferation and invasiveness of cervical carcinoma cells by targeting AKT and EMT.

J Cancer 2020 14;11(6):1625-1633. Epub 2020 Jan 14.

: To explore the relationship and mechanism of LZAP in the occurrence and development of cervical cancer and to provide a new target and intervention method for the treatment of cervical cancer. : Data mining and analysis of LZAP expression levels were performed using several online databases, including The Cancer Genome Atlas (TCGA). A cervical cancer cell line that stably overexpresses LZAP was established, and the effect of LZAP overexpression on cell proliferation, invasion, migration and tumor formation in vivo as well as its mechanism were explored. : Our study shows that the expression of LZAP is upregulated in cervical cancer. The overexpression of LZAP can significantly promote the proliferation, colony formation, and invasion and migration abilities of cervical cancer cells. The tumorigenesis test in nude mice showed that overexpression of LZAP could promote the tumorigenicity of cervical cancer cells in vivo. LZAP could also promote the phosphorylation of AKT at position 473 and the epithelial-mesenchymal transition (EMT). : The expression of LAZP is increased in cervical cancer, which can enhance the invasion, metastasis, and EMT in cervical cancer cells by promoting AKT phosphorylation.

[Prenatal Diagnosis of A Case of SEA-HPFH Deletion Combined with Beta-Thalassemia in A Chinese Family].

Zhongguo Shi Yan Xue Ye Xue Za Zhi 2017 Aug;25(4):1142-1146

Fujian Key Laboratory for Prenatal Diagnosis and Birth Defect, Fujian Provincial Maternity and Children Hospital, Affiliated Hospital of Fujian Medical University, Fuzhou 350001, Fujian Province, China.

Objective: To investigate the prenatal diagnosis of a case of SEA-HPFH deletion combined with beta-thalassemia in a Chinese family.

Methods: Gap-PCR and RDB methods were applied to test the genotype for the family.

Results: Mother showed a SEA-HPFH thalasemia trait phenotype, while her genotype was heterozygote for SEA-HPFH deletion; father showed a beta-thalassemia trait phenotype, while his genotype was heterozygote for IVS-II-654 mutation; the genotype of fetus was normal in these tests.

Conclusion: Regular thalassemia genes and deletion beta-thalassemia genes can be used in prenatal diagnosis of the case at risk for compound heterozygotes of SEA-HPFH deletion and beta-thalassemia.

Molecular characterization of a novel 27.6-kb deletion causing α(+) thalassemia in a Chinese family.

Ann Hematol 2011 Jan 20;90(1):17-22. Epub 2010 Jul 20.

Department of Medical Genetics, School of Basic Medical Sciences, Southern Medical University, Guangzhou, Guangdong 510515, People's Republic of China.

Over 80% of the α-thalassemia cases in southern China are caused by large deletions involving the α-globin gene cluster on chromosome 16p13.3. Here, we characterized a novel 27.6-kb deletion on the α-globin gene cluster in a Chinese family. Its breakpoints were detected to lie between coordinates 9079 and 36718 of the α-globin gene cluster (NG_000006.1), with a total of 27,640 nucleotides deleted. It was designated as -α (27.6) deletion. The proband is a compound heterozygote of --(SEA) and -α (27.6) and he displayed very mild hemoglobin H disease phenotype with Hb 7.9-9.3 g/dl. Phenotypic analysis on heterozygote of this deletion revealed it as α(+) mutation. It leads to a very mild phenotype as adult heterozygotes have normal hematological parameters with the values at the lower border of the normal range. RT-PCR analysis showed that the α-globin mRNA level of the heterozygotes was decreased when compared with that of normal people.
