Objective To investigate the clinical significance of protein expression of Six1 in cervical cancer. Meth?ods The immunohistochemical (IHC) staining was applied to detect the expression of Six1 protein in normal cervical tis?sues (n=32), cervical intraepithelial neoplasia (CIN) tissues (n=49) and cervical cancer tissues (n=123). The localization of Six1 protein was detected in vitro cultured HeLa cells using immunofluorescence (IF) staining. Results The positive rate of Six1was significantly higher in cervical cancer (72.3%) than that of CIN tissues (28.6%) and normal cervical tissues (15.6%,χ2=13.118 and 10.058 respectively, P<0.01). There were significance differences in expression levels of Six1 protein be?tween different tumor sizes and metastasis of cervical cancer (P < 0.01). The Six1 protein showed positive signals in cyto?plasm and nucleoli in HeLa cells. Conclusion Six1 expression is associated with cervical cancer, which may be a potential biomarker for invasion and metastasis of cervical cancer.

Objective To investigate the differences in genotypes and phenotypic parameters of β-thalassemia gene carriers in pregnant women′s from Chengdu, Sichuan Province.Methods Totally 320pregnant women′s withβ-thalassemia gene from March 2016to June 2017in our hospital were selected.Routine blood tests, alkaline hemoglobin electrophoresis and routine analysis ofβ-thalassemia were performed on all the cases.Statistical analysis was performed on the data of each group.Results There were 306cases of heterozygousβmutations and 10types of mutations, among which 14cases ofα-thalassemia combined had 6types of mutations.The mutations of MCV, MCH, MCHC, and Hb in the routine blood tests of each group showed some differences.The incidence of abnormal bands was also different for each mutation, and the hemoglobin electrophoresis results ofβEM mutations contained abnormal bands.However, the clinical manifestations of CAPM mutations were not obvious and easily missed.Conclusion There is a certain regional specificity inβthalassemia gene carrying in Chengdu area.Targeted examination in the preliminary screening and prenatal diagnosis should be conducted so as to reducing the birth rate of children′s with severe thalassemia.

An epidemiological study was performed to know the recent infection status of Paragonimus westermani metacercariae (PwMc) in freshwater crayfish, Cambaroides similis, from 2 streams in Jeollanam-do, Republic of Korea. Crayfish were collected from creeks in Bogil-do (Island), Wando-gun, and in a creek near Daeheung Temple in Haenam-gun. The infection rate of crayfish with PwMc in Bogil-do was 89.8%, and the metacercarial burden was 37 PwMc per the infected crayfish. Crayfish in a creek near Daeheung Temple were larger and twice heavier than those in Bogil-do. Of them, 96.5% were infected with PwMc. An average of 140 metacercariae was found in the infected crayfish, almost quadruple to those of Bogil-do. There was a strong correlation between the number of PwMc and body weight of the crayfish. These results suggest that P. westermani metacercariae are still prevalent in crayfish of the 2 regions in Jeollanam-do, Korea.

OBJECTIVETo delineate the clinical, biochemical and genetic mutational characteristics of a child with mitochondrial complex III deficiency.

METHODSClinical information and results of auxiliary examination of the patient were analyzed. Next-generation sequencing of the mitochondrial genome and related nuclear genes was carried out. Suspected mutation was confirmed in both parents with Sanger sequencing. Heterozygous deletion was mapped with chromosomal microarray analysis and confirmed with real-time PCR.

RESULTSThe patient presented with vomiting, polypnea, fever, metabolic acidosis, hyperlactatemia, hypoglycemia, dysfunction of coagulation and immune system, in addition with increased lactate dehydrogenase and creatine kinase isoenzyme. Elevation of blood alanine and acylcarnitines as well as urinary ketotic dicarboxylic acid were also noted. The patient also presented development delay, mental retardation and hypotonia. Sequence analysis revealed two mutations in the nuclear gene UQCRB, which included a previously reported frameshift mutation c.306_309delAAAA(p.Arg105Lysfs*22) and a novel large deletion encompassing the entire UQCRB gene.

CONCLUSIONThe clinical, biochemical and gene mutation characteristics of a child with mitochondrial complex III deficiency caused by mutations of the UQCRB gene have been delineated.

Objective:To observe the dynamic changes in specific IgG antibodies induced by recombinant hepatitis E vaccine using different immunization strategies in BALB/c mice.Methods:BALB/c, C57BL/6, NIH and KM mice were immunized intraperitoneally with serially diluted hepatitis E vaccine to select a mouse strain appropriately responding to hepatitis E vaccine. Then the selected BALB/c mice were randomly divided into three experimental groups, one-dose immunization group (0 week), two-dose immunization group (0 and 4 weeks) and three-dose immunization group (0, 4 and 12 weeks), and three adjuvant control groups with the same immunization strategy as the corresponding experimental group. Blood samples were collected from the intraocular canthus at different time points and serum antibody levels were detected quantitatively.Results:The BALB/c and NIH mice had proper responses to hepatitis E vaccine administrated at different doses than the C57BL/6 and KM mice, and the antibody positive conversion rates also showed a certain dose-effect relationship. Thus, the BALB/c mice were used as the animal model. The level of specific IgG antibodies in BALB/c mice immunized with one dose of vaccine reached a peak of 44.35 U/ml around the 10th week after the immunization, and then maintained at (5.52-13.28) U/ml after a decrease. The antibody level in the two-dose immunization group increased rapidly after the second immunization and peaked at the 8th week. From the 10th week, it gradually decreased and maintained at (16.50-32.54) U/ml. The trend of antibody changes in the three-dose immunization group was similar to that of the two-dose immunization group during the first 12 weeks, but a significant increase was induced after the third immunization and the level maintained at (62.65-72.61) U/ml for a long time, which was about nine times higher than that of the one-dose immunization group and three times of the two-dose immunization group.Conclusions:This study showed that BALB/c mice were suitable models to study the dynamic changes in specific IgG antibodies elicited by hepatitis E vaccine using different immunization strategies, which provided reference for future research on its in vivo efficacy.

OBJECTIVETo screen fatty acid oxidation disorders (FAOD) in newborns in Zhejiang province.

METHODSA total of 1 861 262 newborns were screened for FAOD in Neonatal Screening Center of Zhejiang Province during January 2009 and December 2016. The blood samples from newborns were screened by tandem mass spectrometry, and diagnosis of FAOD was confirmed by urine organic acid measurement combined with genetic analysis. The prognosis and follow-up of patients with FAOD were also evaluated.

RESULTSOf 1 861 262 newborns screened, 121 cases of FAOD were diagnosed. Among 121 cases of FAOD, primary carnitine deficiency (PCD) was the most common type (=78, 64.5%), which was followed by short-chain acyl-CoA dehydrogenase deficiency (SCADD,=27, 22.3%), medium-chain acyl-CoA dehydrogenase deficiency (=5, 4.1%), multiple acyl-CoA dehydrogenase deficiency (MADD,=4, 3.3%), very long-chain acyl-CoA dehydrogenase deficiency (=3, 2.5%), carnitine palmitoyltransferase Ⅰ deficiency(=2, 1.7%)and carnitine palmitoyltransferase Ⅱ deficiency (CPTⅡD,=2, 1.7%). During 2-82 month follow-up, 15 patients were lost, 4 were dead (1 PCD, 1 MADD, and 2 CPTⅡD), and the remaining 102 subjects had normal intelligence and physical development without any clinical symptoms.

CONCLUSIONSPCD and SCADD are the most common FAODs in newborns in Zhejiang province. Most of FAOD patients are asymptomatic, and have normal growth and development after early intervention and management.

OBJECTIVETo analyze the results and follow up data of screening for newborn organic aciduria in Zhejiang province.

METHODSThe results and follow-up data of 1 861 262 newborns from Zhejiang province undergoing screening for organic aciduria during January 2009 and December 2016 were retrospectively analyzed. The acylcarnitine spectrum in urine samples was detected by tandem mass spectrum (MS/MS) and the positive patients were confirmed by urine gas chromatography mass spectrometry and/or gene analysis.

RESULTSNinety two cases of organic aciduria were confirmed with a prevalence of 1:20 200. Among 40 cases of methylmalonic academia (MMA), 13 (32.5%) were of MMA simple type and 27 (67.5%) were combined type. Genetic analysis showed 6 cases of MUT type and 1 case of CblB type out of 7 patients with MMA simple type, 10 cases of CblC and 1 case of CblF out of 11 patients with combined type, respectively. Six patients had propionic academia with a prevalence of 1:310 200, 7 had isovaleric academia (1:265 900), 6 had glutaric academia type 1 (1:310 200), 27 had 3-methylcrotonyl-CoA carboxylase deficiency (MCC, 1:68 900), 1 had 3-hydroxy-3-methylglutaric aciduria (1:1 861 300), 2 had β-ketothiolase deficiency (1:960 600), and 3 had biotinidase deficiency/holocarboxylase synthetase deficiency (1:620 400). Thirty-one patients had a disease onset at neonatal period, and 15 at post-neonatal period. Thirty-three patients had brain involvements or cranial imaging disorders. Three patients with MMA had kidney diseases or heomlytic uremic syndrome, and 3 had myocardial impairments. Twenty patients died during the follow-up.

CONCLUSIONSMMA is the most common newborn organic aciduria in Zhejiang province. Except MCC, most organic aciduria may lead to metabolism decompensation, complications or even death.
