Objective To study diagnosis and treatment of rhabdomyosarcoma (RMS) in children.Method The clinical data of 43 children with RMS was retrospectively reviewed from Nov 2004 to May 2012.Their long-term survival was followed up.Forty-three children with RMS(male 26,female 17) in Beijing Tongren Hospital were enrolled.Their median age on diagnosis was 6 years old.We confirmed the diagnosis according to pathological diagnosis.Comprehensive treatment included chemotherapy,surgery and implantation of radioactive seeds,and so on.Statistical analysis was used on clinical data and treatment efficacy.Result The median follow up time of 43 cases with RMS in children was 31 mouths until May 2012.Four cases abandoned,39 cases were followed up.The cases of complete remission were 27(69％),and the cases of partly remission were 7 (18％),and the cases of dead were 5 due to cerebral metastasis.Overall survival rate was 87％ (34/39).Eight cases were treated with 125Ⅰ particles implants into its location,7 cases responded,1 case was invalid.Conclusion Although anatomic structure of RMS of head and neck was very complex,and the prognosis of it with metastatic disease was inferior,the muttidisciplinary treatment can still improve the clinical remission rate.In particular,high risk RMS with 125Ⅰ particles implants and large dose chemotherapy would be beneficial.

Objective To validate the analytical performance of three Cys C reagents with particle-enhanced turbidimetric immunoassay(PETIA) method used on the automatic biochemistry analyzer for preliminary clinical application.Methods The performance of three Cys C reagents (labeled as A, B, C) with PETIA method from Shanghai Jing Yuan Co., Beijing Leadman Co. and Beijing Jiuqiang Co. on OlympusAU2700 automatic biochemistry analyzer were assessed.According to the standard of CLSI EP6-A, EP15-A and EP7-P, the precision, linearity range, disturbance (bilirubin, hemoglobin, chyle) were assessed, and compared with those of Cys C reagent based on particle-enhanced nephelometric immunoassay(PENIA) from Dade Behring Co.. The reference ranges for Cys C in serum of 120 healthy individual were evaluated.Results The within-run CVs of the three reagents (A, B and C) were 3.08%-3.2%, 2.3%-4.15% and 1.38%-1.53% respectively.The total CV in A, B and C were 3.29%-3.44%, 2.65%-5.18% and 1.67%-1.69% respectively, lower than the stated.Limits of quantitative determination (LOQ) of the three reagents were 0.41, 0.23 and 0.07 mg/L, basically meeting the testing requirement.The linearity range was 0.22-7.26 mg/L(r=0.996), 0.20-7.72 mg/L(r=0.999)and 0.20-7.62 mg/L(r=0.997)in the three reagents, which demonstrated a sound linear correlation. For interference tests, no remarkable interference (<±10%) of reagent C was detected when bilirubin≤684 μmol/L, hemoglobin≤9.7 g/L and Chyle turbidity≤6 200 FTU; and no significant interference of reagent B was found when bilirubin≤684 μmol/L, hemoglobin≤6.79 g/L and Chyle turbidity≤6 200 FTU; when bilirubin≤684 μmol/L, hemoglobin≤4.85 g/L and Chyle turbidity≤1 240 FTU reagent A was not interfered significantly. The comparison afte and before the high-speed centrifugation reveals that the average percentage of bias for reagents A, B, C measured Cys C in chylous serum samples of patients was -8.31%, 1.52%, 1.32%, respectively.In method comparison tests, the regression equations of the three reagents compared with Dade Behring PENIA Cys C reagent were as follows:Y=0.787X+0.492 (R2=0.976), Y=1.098X+0.137 (R2=0.982) and Y=1.037X+0.249 (R2=0.996), respectively. Agreement rates of the high Cys C in reagent A, B, C and Dade Behring Cys C reagent were 80% (Kappa=0.615,P=0.000), 100% (Kappa=1.000,P=0.000), 91.2% (Kappa=0.824,P=0.000); While for reference range of preliminary clinical assessment, diagnosis coincidence rate of reagent A increased to 98.8% (Kappa=0.974,P=0.000). Conclusions When used in automatic biochemical analyzer, the three Cys C reagent with PETIA showed high precision,sensitivity, and sound correlation with Dade Behring PENIA reagents.The three reagents are all able to meet clinical test requirements, nevertheless, anti-interference capability were diffierent and the reference range should be further validated.

Objective To investigate the applicability of Cys C-based formulas for prediction of GFR in Chinese patients with CKD.Methods A total of 176 adult patients with CKD including 90 males and 86 females collected from 4 hospitals located in different geographic regions of China (Beijing,Shanghai,Dalian and Changsha) were enrolled in this study from September 2007 to July 2009.The rGFR was measured using 99mTc-DTPA clearance rate two-sample method.Cystantic C was measured by PETIA and PENIA respectively.The results of eGFR in the Larsson formula,Grubb formula,Hoek formula,Filler formula,Stevens formula and Hojs formula were compared with the rGFR to evaluate the calculation coherence,bias,precision,accuracy and the performance of correct phasing of the formulas.Results The mean 99mTc-DTPA clearance was [40.70 ( 19.09 - 86.49)] ml · min-1 · ( 1.73m2 ) -1.Significant difference was witnessed in the evaluation of GFR estimation formulas calculated by PETIA and PENIA (P ＜0.01).ICC and Spearman correlation analysis revealed a significant correlation between eGFR and rGFR.The ICCs of eGFR and rGFR ranged from 0.874 to 0.938.Compared with rGFR,the 30％ accuracy of all the eight evaluation formulas using PETIA and PENIA method were lower than 60％.The percentages of correct phasing in all the 5 stages of CKD were not ideal.With these formulas,percentages of correct phasing from CKD stage 2 to CKD stage 4 were lower than 65％.The eGFRs were underestimated by formulas evaluated by PENIA in CKD stage 1.All the eGFRs were overestimated remarkably by all equations in CKD stage 5.Conclusions None of the eight Cys C based formulas are ideal for estimation of GFR in Chinese CKD patients,and they can not be applied to Chinese patients directly.For this patient population,further studies will be needed to develop a more accurate Cys C-based GFR estimation formula that includes ethnicity,age and other factors.

Objective To evaluate the clinical performance of INNOVANCE D-Dimer,and provide information for clinical application.Methods 402 cases of sodium citrate anticoagulant blood were tested with INNOVANCE assay and PLUS assay on CA7000 analyzer to measure plasma D-Dimer levels.VIDAS-30 immunology analyzer was also used to validate the two assays.4 patients with elevated D-Dimer were monitored continuously during 5 days using INNOVANCE assay and PLUS assay respectively,then the consistency of trend between 2 assays was analyzed.Plasma specimens added with hemoglobin,bilimbin and triglyceride were used to verify the anti-interference capability of INNOVANCE D-Dimer assay.Results In 402 specimens,the result ranges of INNOVANCE D-Dimer and PLUS D-Dimer were [2.15 (0.33,8.63)]mg/L FEU and [325.50 (123.75,974.00)] μ,g/L DDU,respectively.The consistency between two assays was poor (Z =-17.375,P =0.000),especially the results in the range of PLUS D-Dimer (201-300) μg/L DDU and (301-400) μg/L DDU,the coincidence rates were only 25％ and 15％,respectively; the coincidence rate was up to 85％ during PLUS D-Dimer (500-600) μg/L DDU; the coincidence rate was close to 100％ when PLUS D-Dimer over 700 μg/L DDU.Totally 47 of 402 cases were unmatched between two assays.Verified by VIDAS 30,83.0％ (39/47) was false negative for PLUS assay,4.3％ (2/47) was false negative for INNOVANCE assay,12.7％ (6/47) was false positive for PLUS assay.There were 5 false positives and 39 false negative for PLUS assay,totally 45 cases; Two false negative for INNOVANCE assay.Four patients with elevated D-Dimer were monitored and the results showed similar trend between 2 assays.For INNOVANCE assay,the capacity of anti-interference to free bilirubin,unconjugated bilirubin,hemoglobin,and triglyceride was up to 217 μmol/L,337 μmol/L,41.04 g/L,18.35 mmol/L,respectively.Conclusions INNOVANCE assay can markedly reduce false negative results of D-Dimer compared with PLUS assay.INNOVANCE D-Dimer has good performance on anti-interference to jaundice,hemolysis and lipemia samples.

Objective To investigate the relationship between single nucleotide polymorphism (SNP) of BARD 1 gene and BRCA1 gene in epithelial ovarian cancer (EOC).Methods Nineteen EOC patients with BRCA1 gene mutation and 50 EOC cases without BRCA1 gene mutation between January 2016 and October 2016 were collected,and all EOC were diagnosed by pathological method.BARD1 gene variants were detected by next generation sequencing (NGS).The SNP of BARD1 gene was analyzed by Pearson linear correlation.Logistic regression analysis was used to research the clinicopathologic features and BRCA1 gene mutation associated with BARD1 gene SNP.Pearson's chi-square test was used to analyze the association between BARD1 gene Val507Met,Arg378Ser and Pro24Ser with different clinicopathologic features and BRCA1 gene mutation risk.Results (1) Eight BARD1 gene variants were found in 69 ovarian cancer patients,in which Val507Met,Arg378Ser and Pro24Ser were common variants,and the rate of mutation were all 54％ (37/69).(2) There was a significant linear correlation among Val507Met,Arg378Ser and Pro24Ser (all P＜0.01).(3) Obvious differences were found in Val507Met,Arg378Ser and Pro24Ser of BARD1 gene between BRCA1+ and BRCA1 (all P＜0.05).(4) No differences were found between BARD1 gene Val507Met,Arg378Ser and Pro24Ser and the clinicopathologic features (all P＞0.05),while obvious differences were found in BRCA1 gene mutation compared to the controls group.The risk of BRCA1 mutation in Val507Met and Arg378Ser were more evident in subjects with negative family history,positive menopause history,negative tubal ligation,onset age (≤60 years old) and sensitivity to platinum-based chemotherapy in EOC (all P＜0.05),while Pro24Ser was only more evident in positive menopause history of EOC (P＜0.05).Conclusions BARD1 Val507Met,Arg378Ser and Pro24Ser are the common genotypes,which are associated with BRCA1 mutation in EOC.The family history,menopause history,tubal ligation,onset age and sensitivity to platinum-based chemotherapy have effects on BARD1 SNP in the risk of BRCA1 gene mutation.

Objective To compare the effects of simple eye movement training and eye movement training combined with traction test on the vision after orbital blowout fracture. Methods 143 cases with orbital blowout fracture after operation were divided into the experimental group (63 cases) and control group (80 cases). The experimental group was treated with eye movement training and passive traction test within 3 days after operation, while the control group was treated with eye movement training alone. The changes of diplopias of all patients were observed. Results The efficient rate in the experimental group was 93.6% (59/63), that of the control group was 72.5% (58/80). The effect of the experimental group was superior to that of the control group (P<0.01). Conclusion The eye movement training combined with traction test can improve the diplopia of the patients with orbital blowout fracture after operation.

Objective To investigate the mutations of BRCA genes in sporadic high grade serous ovarian cancer (HGSOC) and study its clinical significance. Methods Sixty-eight patients between January 2015 and January 2016 from the Affiliated Cancer Hospital of Zhengzhou University were collected who were based on pathological diagnosis of ovarian cancer and had no reported family history, and all patients firstly hospitalized were untreated in other hospitals before. (1)The BRCA genes were detected by next-generation sequencing (NGS) method. (2)The serum tumor markers included carcinoembryonic antigen (CEA), CA125, CA199, and human epididymis protein 4 (HE4) were detected by the chemiluminescence methods, and their correlation was analyzed by Pearson linear correlation. Descriptive statistics and comparisons were performed using two-tailed t-tests, Pearson′s chi square test, Fisher′s exact tests or logistic regression analysis as appropriate to research the clinicopathologic features associated with BRCA mutations, including age, International Federation of Gynecology and Obstetrics(FIGO)stage, platinum-based chemotherapy sensitivity, distant metastases, serum tumor markers (STM). Results (1) Fifteen cases (22%, 15/68) BRCA mutations were identified (BRCA1: 11 cases; BRCA2: 4 cases), and four novel mutations were observed. (2) The levels of CEA, CA199, and HE4 were lower in BRCA mutations compared to that in control group, while no significant differences were found (P>0.05), but the level of CA125 was much higher in BRCA mutation group than that in controls (t=-3.536,P=0.003). Further linear regression analysis found that there was a significant linear correlation between CA125 and HE4 group (r=0.494,P<0.01), and the same correlation as CEA and CA199 group (r=0.897,P<0.01). (3) Single factor analysis showed that no significant differences were observed in onset age, FIGO stage, distant metastasis, and STM between BRCA+and BRCA- group (P>0.05), while significant differences were found in CA125 and sensitivity to platinum-based chemotherapy between the patients with BRCA mutation and wild type (P<0.05). The multiple factors analysis showed that the high level of CA125 was a independent risk factor of BRCA mutations in sporadic HGSOC (P=0.007). Conclusion The combination of CA125 with BRCA have great clinical significance, the mutation of BRCA gene could guild the clinical chemotherapy regiments.
