Objective To evaluate the clinical value of multiplex ligation-dependent probe amplification (MLPA) technique used in karyotype analysis of chorionic villi from missed abortion. Methods Feb 2008 to Oct 2008, 91 patients with missed abortion diagnosed by hormonal measurement, type B ultrasound and physical exam matched with 20 normal pregnant women undergoing artificial abortion were enrolled in this study. Chorionic villi was obtained by suction dilation and curettage in aseptic condition, then those villi was cultured and analyzed by traditional cytogenetic karyotyping method, in the mean time, the DNA extracted from villi was detected by MLPA. The results of chromosomal G-banding of chorionic villi were compared between two methods. Results The diagnostic concordance of MLPA and traditional karyotyping was observed in 92% (84/91) cases, there were 84 cases in the case group with diagnostic concordance by traditional karyotyping and MLPA except 7 cases of euploidy could not be detected by MLPA. The 84 cases included 40 normal karyotype,29 trisomy of euchromosome, 1 double trisomy of euchromosome, 10 monosomy X , 1 monosomy X combined with trisomy of euchromosome, 2 chimaera of X chromosome, 1 structural abnormity of euchromosome. Among 7 cases with discordance diagnosis, 2 cases with trisomy and 5 cases with tetrasomy of euchromosome were identified in traditional karyotyping, however, they were all diagnosed with normal disomy by MLPA. Of 20 villi from normal pregnancy, two methods got the consistent results. Conclusion The MLPA was rapid and efficacy method used for analyzing aneuploids in chorionic villi.

Conclusion Motomed Gracile can facilitate the recovery of children with spastic cerebral palsy.

Objective To investigate the expression and clinical significance of platelet activating factor [PAC]-1, CD62P and TPP hi severe sepsis. Method Patients with severe sepsis who were admitted into the EICU of Subei People's Hospital from April 2007 to March 2008 were included. Patients with severe sepsis (Group Ⅲ)were treated according to the treatment guidelines for severe sepsis, and were divided, according to their clinical records, into those who survived and those who died within 28 days of admission. Patients admitted during the same period with symptoms of infection but without severe sepsis were included as the General Infected Group (Group Ⅱ). A Control Group (Group Ⅰ) comprised patients who visited the hospital over the same period for physical examination or the healthy volunteers. The group members were all included randomly, and the gender and sex of patients in all three groups were similar. Patients with acute brain infarction, acute coronary syndrome,serious diabetes, hyperlipidemia, malignant tumor, leukemia, primary liver, renal and hematopoietic system dis-eases,long-term bedridden patients, pregnant women, and patients taking hormone treatment or hranunosuppres-sants were excluded from the study. Morning venous blood was collected and ELISA and Flow Cytometry performed on the fwst day of admission for Groups Ⅰ- and Ⅱ, and on the first, third and fifth day after admission for Group Ⅲ, to determine the TpP,PAC-1 and CD62P respectively; and the Marshall score was determined. Data were ana-lyzed by SPSS 12.0 software. For continuous variables, comparisons among groups were analyzed by ANOVA.Levene's and LSD test were applied to assess homogeneity. Bivariate test is applied to Correlation Analysis. P<0.05 was regarded as a statistically significant difference. Results There were a total of 20 patients each in GroupⅠ-and GroupⅡ, and 30 in Group Ⅲ; of these, 19 were classed as survivors and 11 died during the 28-day peri-od. On the first day of admission, there were no significant differences in PAC-1, CD62P or TpP expression between Groups Ⅰ- and Ⅱ(P>0.05); however, Group Ⅲ was significantly different compared with both Group Ⅰ and Group Ⅱ (both:P<0.05). The expression of PAC-1, CD62P and TpP tended to decline in the survivor group,and became normal with the treatment process, while the expression of PAC-1 ,CD62P and TpP in the patients who died remained high, and even increased significantly over time. On the first day, the expression of CD62P and TpP in the patients who survived and in those who died was not significantly different (P>0.05); on the third day,however, a significant difference appeared with values of (2.89±1.48) % vs. (5.04±2.57) % (P<0.01) for CD62P, and (5.24±2.22) mg/L vs. (9.20±1.93) mg/L (P<0.01) for TpP. The expression of PAC-1 was significantly different between the two subgroups on the first day, with values of (3.15±0.42)% vs. (5.30±.48)% (P<0.01). The Marshall score of the two groups showed similar changes. Correlation analysis showed that PAC-1, CD62P and TpP were significantly correlated with the Marshall score. Conclusions Platelet activation and microthrombosis existing in the early stage of severe sepsis work together in the early hypercoagulable state.They both play important roles in disease development and progression. The dynamic detection of CD62P and TpP is beneficial to the diagnosis and prognosis of severe sepsis.PAC-1 appears to hold a risk stratification effect, as pa-tients with high expression of PAC-1 in the early stage show poor prognosis. Therefore, PAC-1 could be used as a marker of severe sepsis and poor prognsis.

0.05), CGI and HAMA.

Objective To investigate the characteristics of activation-induced cytidine deaminase (AID) expression level in de novo acute leukemia (AL) patients, chronic myeloid leukemia chronic phase (CML-CP), chronic myeloid leukemia blastic crisis (CML-BC) patients and leukemia cell lines. Methods The expression level of AID mRNA was measured in 89 cases of newly-diagnosed acute lymphoblastic leukemia (ALL) patients, 79 cases of de novo acute myeloid leukemia (AML) patients, 5 cases of CML-BC patients, 5 cases of CML-CP patients and leukemia cell lines NB4, THP-1, KG-1, Raji, K562 by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR), bone marrow mononuclear cells of 16 normal healthy donors were used as the control group. Results The expression levels of AID mRNA in 89 cases of ALL and 79 cases of AML were 0.006-7 463.175 and 0.005-69.107, the median expression levels were 3.785 and 1.812, the expression level of AID mRNA in the normal control group was 0.146-4.707, and the median expression level was 1.483, respectively. The AID expression levels of ALL, B-ALL, Burkitt leukemia, M4 patients and Raji cells were significantly higher than those of the normal control group (all P <0.05). Nevertheless, the AID mRNA expression levels of M3 patients and NB4, KG-1 cells were lower than those of the normal control group (all P <0.05). Furthermore, the AID mRNA expression levels of K562 cell were strikingly higher than that of the CML-CP patients (P<0.001), so were those of CML-BC, chronic myeloid leukemia myeloid blast crisis (CML-MBC), chronic myeloid leukemia lymphoblastic blast crisis (CML-LBC) patients. Conclusion AID gene shows high expression level in B-ALL, Burkitt leukemia and M4, low expression level in M3 and KG-1 cells, and obvious high expression level in CML-BC.

OBJECTIVE: To explore the change rules of peak area ratio of STR loci to Amelogenin (AMEL) locus (STR/AMEL), a sex-determining gene in DNA degradation, and to evaluate the application of STR/AMEL value in the estimation of DNA degradation degree. METHODS: DNA was extracted from iliopsoas, and the variations of STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) were analyzed after the artificial degradation was made by DNase I, and the changes of these three ratios of the iliopsoas naturally degraded in an outdoor environment were also analyzed. The regression curves were analyzed using the periods of DNA degradation and outside the body as the independent variable (x) and the STR/AMEL value as the dependent variable (y) and three curve equations under two conditions were established. RESULTS: Both under the conditions of artificial and natural degradation, STR/AMEL value had a negative relationship with the degradation time. The relationship between STR/AMEL and degradation time can be well simulated by the cubic function. R2 was over 0.99 under controlled degradation condition and over 0.86 under natural degradation condition. CONCLUSION The STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) is negatively related with the DNA degradation degree, which follows mathematical regression models strictly, and it might be applied to evaluate the DNA degradation degree.

The ECM25 deletion mutant of industrial brewing yeast, G03/a, was constructed by replacing the ECM25 gene with the kanMX gene. The transformant was verified to be genetically stable. The PCR analysis showed that ECM25 gene in the G-03/a was deleted. Under aerobic conditions of ll degrees C and 28 degrees C, compared with the host strain G-03, the excretive glutathione concentration of G-03/a increased by 21.4% and 14.7%, respectively. Strains G-03 and G-03/a were inoculated in flasks and cultivated continuously for 4 generations. Compared with the host strain G-03, the glutathione concentration in the main fermentation broth and final beer of strain G-03/a increased by 32.1% and 13.8%, the stability index (SI) increased by 7.7% and 5.3%, respectively, and the flavor resistance staling value (RSV value) in final beer increased by 45.0%. During EBC fermentation, the glutathione concentration in the main fermentation broth of strain G-03/a increased by 34.0%, compared with the host strain G-03. Furthermore, no significant difference in routine fermentation parameters was found. The strain G-03/a is proved to be an excellent anti-staling brewing yeast to improve beer flavor stability.
