Objective To establish a new effective method by using real-time polymerase chain reaction (PCR) to detect single nucleotide polymorphism (SNP) typing for rapid identifying apolipoprotein E alleles.Methods To determine alleles of human apolipoprotein E genetic polymorphism at Cys112Arg locus was detected by PCR melting curve analysis with fluorophore SYBR Green I. In order to increase the speciality of SNP assays, high fidelity Taq polymerase was used. The reliability of SNP typing was validated by comparison with the results of direct DNA sequencing.Results Each sample was determined by double tubes, and two melting curves were analysis. As compared the Tm value of samples with the Tm of standard substance, the apoE genotype of samples was determined. The apoE genotype of 30 samples were E3/3 (27/30) and E3/4 (3/30) respectively, which was accordant with the results of PCR-RFLP and DNA sequencing.Conclusion The presented allelic assay was specific, easy to operate and applicable for discrimination of apolipoprotein E genotyping of human blood.

OBJECTIVE To study the HBV-DNA level and its replication with only HBsAb positive for transplantation. METHODS Serial serum samples were studied with the quantitative determination of HBV-DNA by a quantitative PCR assay and determination of HBsAb by ELISA. RESULTS The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the amount between 10~4-10~6 copies/ml.The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the level between 10~4-10~6 copies/ml. CONCLUSIONS Patients with only HBsAb positive are still infective,which should be paid attention in transplantation.

[Objective] To construct a database for the genetic polymorphism of 18 STR loci (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, PentaE, PentaD, SE33) in Hart population from Zhejiang province. To investigate the application of 18 STR loci in the field of paternity testing and prenatal diagnosis. [Methods] Fluorescent dye labeling multiplex STR-PCR, capillary electrophoresis and DNA sequencer GeneScan were adopted in genotyping 598 unrelated samples collected from Han population in Zhejiang province. 18-STR database was established and analyzed. Population comparison was conducted between Han population in Zhejiang province and 8 other population. 15-STR and 18-STR identification system were compared in 497 paternity testing cases. [Results] We observed the distribution of 18 STR loci in Han population meet Hardy-Weinberge equilibrium and was different from other 8 population (X~2 test, P>0.05). Statistical results showed that the heterozygosis (He) ranged from 0.630 to 0.942. The combined power of discrimination was>0.9999999999. Compared with 15-STR identification system, higher paternity index scores and higher exclusion rate were obtained with 18-STR identification system in dual-case paternity test and mutation identification. One trisomy 21 fetus was found in a prenatal paternity test case which had two characteristic genotypes in 2 STR loci of D21S11 and Penta D. [Conclusions] The 18 loci were relatively highly genetic polymorphic in Zhejiang Han population and could be used for paternity testing. Some STR loci could be used in prenatal diagnosis for aneuploidy.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.

OBJECTIVETo explore the relationship between occupational stress and serum glycosylated hemoglobin A1c (HbA1c) level.

METHODSA cross-sectional epidemiological study was conducted in 115 dispatchers. The occupational stressors, personality, occupational strain and coping with stress were measured using Occupational Stress Instrument. Serum HbA1c levels were measured by stratigraphic analysis of cation exchange resin.

RESULTSSerum HbA1c level (6.63% ± 1.93%) in the shiftwork group was significantly higher than that (5.73% ± 1.57%) in the daily relay work group (P < 0.05). Spearman correlation analyses showed the positive correlation between type A behavior and serum HbA1c level (r = 0.221), the negative correlation between organizational commitment and serum HbA1c level (r = -0.218). Variance analyses revealed that serum HbA1c levels among high, middle and low job requirement groups and job control groups were significantly different (P < 0.05). There were significant differences of serum HbA1c levels among different type A behavior, internal control, susceptibility of stress and organizational commitment groups (P < 0.05). Stepwise regression analyses indicated that shiftwork affects obviously serum HbAlc level, internal control and job future were the predictors of serum HbA1c level (R2 = 0.082).

CONCLUSIONSerum HbA1c may be a potential biomarker in field investigation of the effects of occupational stress.
