ObJective To explore the value of acute physiology and chronic health evaluation Ⅲ(APACHE Ⅲ ) score and the concentration of serum cholinesterase (ChE) in predicting the condition and prognosis of patients with severe acute pancreatitis (SAP) within 24 hours afar hospitalization.Methods Sixty-two SAP patients were enrolled and APACHE Ⅲ score was assessed and the concentration of serum ChE was detected within 24 hours after hospitalization.The correlation between the concentration of serum ChE,APACHE Ⅲ score and the condition and prognosis was analyzed.Results There were 44 survivalcases and 18 dead cases.The APACHE Ⅲ score of the surval patients was significantly lower than that of the dead patients [(52.16 ± 13.76) scores vs.(97.10 ± 15.85) scores] (P＜0.01).The concentration of serum ChE of survival patients was significantly higher than that of the dead patients [ (3685 ± 466) U/L vs.(2109 ± 345) U/L] (P＜ 0.01 ).The higher APACHE Ⅲ score was,the lower the serum ChE concentration was,and the higher the mortality rate was.APACHE Ⅲ score and the concontration of serum ChE both had statistical significances compared with the prognosis in the Logistic regression analysis (P =0.0043,0.0075);APACHE Ⅲ score (95％ CI 1.0306-1.1507),the concentration of serum ChE (95％ CI0.9986-1.0125 ).ROC areas under curve (AUC) of APACHE Ⅲ score,serum ChE concentration with the prognosis were 0.936 and 0.882,respectively.There was no significant difference (P=0.0820).In combined prediction of APACHE Ⅲ score and serum ChE concentration,AUC was 0.952,and its predicting accuracy was higher than either APACHE Ⅲ score or serum ChE concentration (P=0.0016,0.0027).Conclusions APACHE Ⅲ score and the concentration of serum ChE both are significantly correlated with the condition and prognosis of SAP patients.Their combined detection can significantly improve the accuracy of prognosis judgement and provide some clinical guidances for treatment.

Objective: To modify EBP(endotoxin binding peptide), clone and express the mutate of EBP gene and gain purified mEBP.Method: mEBPgene was cloned by PCR site-directed mutagenesis. PinpointXa-3/mEBP expression vector was designed to express human mEBP as a fusion protein in BL21 (DE3) pLysS. Digested engineering bacteria by lysozyme and collected inclusion bodies.Fusion protein was purified by Pinpoint TM Xa purification system and cleaved by factorXa,mEBP was purified by RP-HPLC. Results: Mutations at residues 5 and 18(Gln→Lys) was obtained by PCR site-directed mutagenesis, expressed and purified mEBP successfully.Conclusions: Obtaining of purified mEBP lay a foundation for its biological activity research.

The technique introduced in this paper is applied in the endocardial catheter operation, which describes the 3D heart model reconstruction before the operation for the endocardial navigation. After a series of CT images of the thorax are processed, an accurate 3D endocardial model can be reconstructed. At first, the series of 2D CT images are preprocessed for denoising and the enhancement,then they are constructed as the volume data. After the region growing segmentation in the 3D volume data according to the grey value of the voxel in the heart cavity, the heart surface rendering is got and the 3D model of endocardial cavity is reconstructed.

A system analysis about the microbial flora of normal and abnormal soybean sauce liquor from the high-salt-level watery state fermentation was made and the dominant bacteria and yeasts were identified.On the other hand,a discussion of effect of temperature on microbial flora was made.The results indicated that there were no obvious differences about the count of aerobe,spore-producing bacteria,enterobacteriaceae,lactic acid bacteria and anaerobe between the normal and abnormal soybean sauce liquor and there were marked differences about the count of yeasts and salt-tolerant bacteria.The predominant yeasts in normal soybean sauce were Torulopsis and Saccharomyces,accounting for 55.9% and 35.3% of the total yeasts separately,and in abnormal soybean sauce were Pichia,candida and Saccharomyces,accounting for 62.8%,17.9% and 9.0% respectively.

These years with industrial antiseptics and disinfectants widely used, especially unscientifically used, the resistance of microorganisms is more and more serious, which brought much more difficulties to industrial producing. The developments on the resistance of microorganisms to industrial antiseptics and disinfectants, their resistant mechanisms and the control strategies are reviewed, which aids us to reasonably use industrial organic antiseptics and disinfectants in existence and provides academic and scientific basis.

Objective To investigate the clinical efficacy of heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine in treating lumbar intervertebral disc herniation. Methods One hundred and twenty patients with lumbar intervertebral disc herniation were randomized to treatment and control groups, 60 cases each. The treatment group received heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine and the control group, heat-sensitive point medicinal moxibustion alone. The VAS score and the JOA Score for Back Pain score were recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the JOA Score for Back Pain score and the VAS score in the two groups (P<0.01). There were statistically significant post-treatment differences in the JOA Score for Back Pain score and the VAS score between the treatment and control groups (P<0.01). The excellent and good rate was 80.0％ in the treatment group and 55.0％ in the control group; there was a statistically significant difference between the two groups (P<0.01). Conclusion Heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine is an effective way to treat lumbar intervertebral disc herniation.

OBJECTIVETo determine the mutation responsible for the congenital fibrosis of the extraocular muscles type I(CFEOM1) in a Chinese family.

METHODSDirect sequencing of exons 20 and 21 in the KIF21A gene was performed for the proband. The mutation c.2860C to T in exon 21 was examined by allele specific-PCR (AS-PCR) analysis in other family members. Haplotype analysis was performed using four STR markers (D12S1668, D12S2194, D12S331 and D12S1048).

RESULTSA heterozygous mutation c.2860C to T in the KIF21A gene was identified in all three affected members with CFEOM1. Haplotype analysis suggested that the mutation might derive from maternal germline mosaicism.

CONCLUSIONThis Chinese family with CFEOM1 may be caused by a c.2860C to T mutation in the KIF21A gene.

OBJECTIVEAt present, blood and skin biopsy tissues are used in the fluorescent in situ hybridization (FISH) test for the diagnosis of Down's syndrome, however, the samples are usually obtained invasively. This study explores the value of oral mucosa cast-off cells in the FISH test, as samples obtained non-invasively, for the diagnosis of this disorder.

METHODSPeripheral blood and oral mucosa cast-off cells were sampled for the FISH test in 16 children with suspected Down's syndrome between March 2010 and March 2011. Chromosomal karyotype analysis of peripheral blood lymphocytes ("gold standard" for the diagnosis of Down's syndrome) was also conducted.

RESULTSThe FISH test, in which both peripheral blood and oral mucosa cast-off cells were examined, showed that 14 children had 21-trosomy syndrome and the other 2 children had normal numbers of cromosome 21. The results of the FISH test were the same as the results of the chromosomal karyotype analysis.

CONCLUSIONSUse of the FISH method to test samples of oral musoca cast-off cells is non-invasive and reliable for the diagnosis of Down's syndrome in children, and is hence worthy of recommendation.
