BackgroundHigh myopia is one of leading causes of blindness,so far the pathogenesis remains unclear.Two single-nucleotide polymorphisms (SNPs) of rs6885224 and rs12716080 in CTNND2 gene were recently found to be associated with high myopia in Singaporean Chinese.But whether these SNPs are related with the pathogenesis of high myopia in Han Chinese is worth studying,Objective This study was to investigate the relationship between the genetic variations of the CTNND2 gene and high myopia in Han Chinese.MethodsA case-controlled association study was designed.Nine hundred and thirty-three individuals with high myopia and 1227age- and gender-matched normal subjects were included in this study.The 5 ml of periphery blood was obtained from all subjects for the extraction of genomic DNA.The target DNA was amplified using PCR and purified by the SNaPshot method.Four SNPs rs12716080,rs917012,rs6885224 and rs16901340 in the CTNND2 gene were genotyped.This study was approved by the Ethic Committee of Sichuan Provincial People Hospital.Written informed consent was obtained from each subject before his/her enrollment.Results The frequencies of the genotypes rs6885224,rs12716080,rs917012,rs16901340 SNPs were in Hardy-Weinberg equilibrium (HWE) ( P=0.181,0.085,0.732,0.313,0.264,0.663,0.084,0.196).There were no significant differences in genotypes frequency distribution ( in turn P =0.654,0.406,0.828,0.403 ) and allele frequency distribution of the CTNND2 gene ( in turn P =0.377,0.209,0.743,0.198) between the high myopia group and normal control group.The haplotypes (TA and GA)frequencies of rs12716080 and rs917012 in the high myopia group were significantly different from those of the normal control group(TA:0.784 vs.0.719;GA:0.087 vs.0.136) (x2 =6.115,P=0.013 ;x2 =6.634,P=0.010),but those of GG were similar between the high myopia group and normal control group ( 0.123 vs.0.143,x2 =0.889,P =0.346). ConclusionsThe SNPs rs12716080,rs917012,rs6885224 and rs16901340 in CTNND2 gene were not responsible for high myopia,however,the haplotypes of rs12716080 and rs917012 are susceptible for high myopia in Han Chinese.

Objective To study the gene mutations and clinical features of mandibuloacral dysplasia with type A lipodystrophy (MADA) in a Chinese family. Methods The information of 5 family members including 2 siblings suspected atyp-ical progeria was assembled. Genomic DNA was extracted from peripheral blood of 5 family members, the 12 exons of LMNA gene were ampliifed by PCR and then the PCR products were directly sequenced and analyzed by using Blast software online. The SIFT and PolyPhen-2 software were used to predict the harmfulness of mutations. Results The 2 siblings were clinically diagnosed as MADA. Heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations were detected in this family. The father carried c.1583C>T (p.Thr528Met) mutation, the mother carried c.1579C>T (p.Arg527Cys) mutation, and their normal daughter were all heterozygous carriers with c.1583C>T (p.Thr528Met) mutation. Compound heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations in 2 siblings led to MADA. The MADA showed an autosomal re-cessive inheritance pattern in this family. Conclusions The 2 siblings with MADA in this family were caused by compound heterozygous mutations in LMNA gene.

Objective To establish an ELISA for detecting antibody against Aspergillus fumigatus pectate lyase A(anti-PlyA),and evaluate its diagnostic value for invasive aspergillosis (IA).Methods An indirect ELISA for IgG antibody a-gainst PlyA was established using PlyA as coating antigen.The serum from 97 IA patients,80 non-IA patients and 200 healthy donors were tested,the results were compared with anti-DPPV (antibody against Aspergillus fumigatus dipeptidyl peptidase V fragment)and anti-TR (antibody against Aspergillus fumigatus thioredoxin reductase).Results The intra-as-say coefficients of variation of the ELISA method for detecting anti-PlyA was 5.3%,and inter-assay coefficients of variation was 10.9%.The sensitivity and specificity of diagnosis of IA were 62.9% and 90.4%,respectively.The positive rates of an-ti-PlyA in non-neutropenic and neutropenic IA patients were 43.8% and 72.3%,respectively (χ2 =7.493,P <0.05).There was no significant difference between the positive rates of anti-PlyA (62.9%),anti-TR (60.8%),and anti-DPPV (67.0%) (χ2 =0.562,P > 0.05).When combined anti-PlyA,anti-TR,and anti-DPPV,the diagnostic sensitivity for IA patients in-creased to 92.8%.Conclusion An ELISA for detecting anti-PlyA was successfully established.The diagnostic value of these three kinds of antibody was superior in non-neutropenic IA patientsto that in neutropenic IA patients.The combined detec-tion of three antibodies could provide higher sensitivity.

Objective To summarize our experience in the diagnosis and treatment of malignant peritoneal mesothelioma(MPM). Methods Clinical data of 10 patients admitted with MPM were analyzed retrospectively. Results The main symptoms of MPM were intraabdominal mass and abdominal pain in these patients; Seven patients were of localized type, 3 cases were of diffused type; Preoperatively 7 cases were misdiagnosed as other intraperitoneal tumor, 9 patients underwent laparotomy and tumor resection for a total 16 times, including once in 4 cases, two times in 3 cases, and three times in 2 cases. Seven patients received curative resection in initial operation. Five patients died within one year, 6 cases within two years, Tumors recurred postoperatively in 4 cases. 1 case is still survival 9 years after. Conclusion Being comparatively rare, MPM is often misdiagnosed, the prognosis is very poor, curative resection sometimes provides a long survival for localized type of MPM, when combined with perioperative comprehensive therapy.

Objective To detect levels of IL - 4 and INF - ? in induced sputum dynamically in children with mycnplasma pneamo-niae pneumonia( MPP), and to analyze the function of Th1 /Th2 cell factor immune response in the genesis and development of MPP, so as to evaluate the clinical value of induced sputum method in MPP research. Methods There were 38 cases who were diagnoses as MPP using 3% high osmotic pressure of saline water to ultrasonic atomizing inhalation for inducing sputum. ELISA was used to detect IL-4 and INF-?. Results The content of IL-4 in acute stage was higher than that in convalescence stage in induced sputum of MPP children. Severe stage was higher than mild stage. However, the comparison between acute and convalescence stage didn't have statistics difference in the content of INF-?, neither did the comparison between severe and mild stage. IL- 4/INF- ? in acute stage was higher than that in convalescence stage. Severe stage was higher than mild stage. In convalescence stage, the comparison of INF - ?, IL - 4, IL - 4/INF - ? between the severe and the mild didn' t have statistic significance. Conclusions IL-4 and INF - ? have participated in the monogenesis of MPP. The disequilibria of Th1 /Fh2 is existed in MPP and Th2 reaction predominates. So induced sputum analysis can be a better way to judge the light or heavy press degree of MPP practically, conveniently and sensitively.

Objective To detect the existence of vasculogenic mimicry in hepatocellular carcinoma (HCC). Methods In this study 42 patients with a total of 47 HCC nodules underwent radical resection.Histological and immunohistochemical double staining of CD31 and PAS were applied to observe the existence of vasculogenic mimicry ( VM ). Reverse tanscription PCR (RT-PCR) were applied to study the expression of VE-cadherin, EPHA2 and MMP-2 genes. Results VM was found in 16 of the 42 (38. 1% )HCC cases. The typical forms of VM in the microscope are vessel-like structure formed by tumor cells,without endothelial cells and the PAS-positive looping pattern. The existence of VM in HCC correlates to a higher Edmondson grade, higher capacity of intrahepatic disseminating and poorer tumor-free survival time (P＜ 0. 05). Comparing the difference of VE-cadherin gene, EPHA2 gene and MMP-2 gene expression between VM positive nodes and in VM negative nodes by RT-PCR method demonstrated that VE-cadherin gene, EPHA2 gene and MMP-2 gene have a more intense expression in VM positive nodes than in VM negative nodes ( P ＜ 0. 05 ). Conclusion VM exists in human hepatocellular carcinoma. VM occurred more frequently in higher malignant HCC and predicts a higher rate of tumor recurrence and poorer prognosis.
