Genetic analysis from forensic microsamples is a urgent, difficult task in forensic science, because it is frequently limited by the amount of specimen available in forensic practice, much effort has been carried out to resolve this difficulty. Whole genome amplification (WGA) technology, which was developing quickly in these years, has been thought to be a powerful, reliable and efficient strategy in analysis of minute amount DNA on many fields. In this review, we discuss its application in forensic science.

OBJECTIVETo assess factors predisposing to proteinuria in patients with type 2 diabetes mellitus (DM).

METHODSA case-control study was conducted on two groups of patients with type 2 diabetes without proteinuria (urine protein < 300 mg/24 h, n = 106) and with proteinuria (urine protein >or= 500 mg/24 h, n = 106). The two groups were matched by age (+/- 3 years), sex, race and place of residence. Information on these subjects including demography, history of disease, family history of diseases, lifestyle and behavioral variables, were obtained through questionnaire. Variables including blood pressure, fasting blood glucose (FBG), quantity of protein in 24-h urine were measured. Cox's proportional hazards regression analysis was then performed.

RESULTSFactors that were independently associated with the development of proteinuria, would include occupation, diabetic duration, glycemic control, hypertension, duration of hypertension and daily intake of vegetable after diagnosis of DM. Their corresponding odds ratios (OR) with 95% confidence intervals (CI) were 2.429 (1.299 - 4.542), 1.078 (1.029 - 1.131), 2.316 (1.341 - 3.998), 1.810 (1.059 - 3.092), 1.043 (1.012 - 1.074) and 0.551 (0.334 - 0.907), respectively, while the presence of proteinuria was not associated with family history of DM, family history of hypertension, certain dietary habits and smoking habit. Multivariate logistic regression model was then fitted with three variables, including diabetic duration, glycemic control and hypertension.

CONCLUSIONThe prevalence of proteinuria in labor workers was higher than that in intellectuals. Longer history of diabetic duration, poor glycemic control, hypertension and longer duration of hypertension all independently contributed to the development of proteinuria. The risk of proteinuria decreased with increasing daily intake of vegetables after the patients being diagnosed as having DM.

OBJECTIVEThis study was undertaken to investigate the clinical features of oral motor dysfunction and feeding problems as well as the nutritional status of children with cerebral palsy (CP).

METHODSFifty-nine CP children, 39 boys and 20 girls, mean age 31 months (20 to 72 months), were recruited. Their parents were interviewed for high risk factors and feeding history. Each case was assessed for oral motor and feeding problems based on oral motor and feeding skill score; for nutritional status by measurement of weight, height; neurologically for type of cerebral palsy and for developmental age by Gesell's developmental scale. Equal number of age and sex matched controls were included for comparison of nutritional status, oral motor and feeding skill score.

RESULTSAmong 59 patients, 51 cases had oral motor dysfunction and 55 cases had feeding problems including all athtosis, spastic tetraplegia, and 16 had spastic diplegia. The scores of both the mean oral motor function and feeding skill of CP children were significantly lower than those of the controls (P < 0.001). Main food of children with cerebral palsy consisted of liquid and semisolid diet. Body weight and height below the 25th percentile were found in 13 cases and 19 cases, respectively.

CONCLUSIONSThe majority of the children with cerebral palsy had oral motor dysfunction and feeding problems which appeared in early age and disturbed the growth and nutritional status. Thorough assessment for oral motor function, feeding problems and nutritional status of CP children is indicated in order to start timely rehabilitation and nutritional interventions which can significantly improve their nutritional status and quality of life.

OBJECTIVETo investigate the effects of inward rectifier potassium channel blockers (BaCl2, CsCl) on the functions of endothelial progenitor cells (EPCs).

METHODSDensity gradient centrifugation-isolated rat hone marrow mononuclear cells were cultured in vitro. EPCs were harvested and seeded on six culture dish when cells grew to 3-5 passages. Before testing the EPCs were synchronized with M199, which contain 2% fetal calf serum. In the end, EPCs were treated with different intervention. The experiment mainly included two parts: (1) BaCl2 (100 micromol/L) and free BaC2 of Tyrodes solution; (2) CsCl (1 mmol/L) and control. Cell pretreated with blockers above mentioned for 12 h, then the gene expression of stromal cell-derived factor-1 (SDF-1), epoprotenol (PGI2) were assessed, beyond that the ability of adhesion, migration were assayed with different tests. In addition, the medium was collected when EPCs were treated for 3 days. The levels of SDF-1 were measured by sandwich enzyme-linked immunosorbent assay (ELISA). Going even further, EPCs were treated with the signal pathway blockers in advance, after repeat the above steps, in order to analyze the change of SDF-1 and then discuss its mechanism.

RESULTSCompared with control group, BaCl2, CsCl could increase EPC adhesion and migration to same extent. Moreover, the gene expression of SDF-1, PGI2 was significantly up-regulated and the production of SDF-1 increased evidently. Furthermore, the mechanism of SDF-1 secretion increasing mainly was associated with eNOS signaling pathways.

CONCLUSIONBa2+ and Cs+ play important roles in increasing EPCs functions, such as adhesion, migration and secretion.

Objective To evaluate the association of islet autoantibodies [ glutamic acid decarboxylase antibody(GADA),protein tyrosine phosphatase antibody(IA-2A)and insulin autoantibodies(IAA)1 with HLA- DQ genotypes in the first-degree relatives of autoimmune type 1 diabetes mellitus.Methods This was a cross- sectional and case-control study.Three hundred and fifty-one first-degree relatives with normal glucose tolerance of patients with type 1 diabetes mellitus and 376 healthy controls were recruited and measured for GADA,IA-2A and IAA by radioligand assay,and 156 first-degree relatives of patients with autoimmune type 1 diabetes mellitus and 278 controls were typed for genetic polymorphisms of HLA-DQ with PCR sequencing-based typing method.Results (1)DQA1*03,DQBI*0303,*0401 alleles and DQA1 * 03-DQBI * 0303,DQA1 * 05-DQBI * 0201,DQA1 * 03-DQBI * 0401 haplotypes were significantly increased in the first-degree relatives of autoimmune type 1 diabetes mellitus(P

Objective To investigate the expression of inregrin?_3 and integrin?_1 in breast cancer and its bio- logical significance.Methods Immunohistochemical assay was used to determine the expression of integrin?_3 and integrin?_1 in the breast cancer(32 cases).Results In normal breast tissue,the positive expression rates of integrin?_3 and integrin?_1 were 0 % and 25 %.In the breast cancer tissue,the positive expression rates of integrin?_3 and inte- grin?_1 were 36 % and 81%.Conclusion The integrin?_3 and integrin?_1 are close associated with the biological sig- nificance of breast cancer.To examine its expression is useful to evaluate the aggressive degree,metastatic potential and prognosis in patients with breast cancer.

Objective To establish a rapid assay with high sensitivity and specificity based on the sequences for group specific gene (GS) and pathogenicity island pag A gene.Methods The PCR primers and probes were designed after the whole sequence was systemically analyzed with bio-informafion tools and blasted with Genebank database.The amplicons were inserted into plasmids so that they could be used as the standard templates to evaluate the sensitivity of the diagnostic system.This assay was based on TaqMan probes and portable Smartcycle PCR machine.Results The detection level was approximately 100 copies per reaction.There was no cross-reaction with other species of Bacillus.This assay could be completed in one hour in laboratory.Conclusion The duplex TaqMan PCR assay could be used to detect Bacillus anthracis rapidly with high sensitivity and specificity.

Pure culture of Phlebopus portentosus was inoculated in the roots of coffee tree. The results indi-cated that the young fruit bodies would come out around the rhizomes of host tree after inoculation in 30 to 90 days, single or cluster, 3 to 4 days for mature, weight 20.0 g to 62.0 g. Brown rhizomorph and hyphae can be seen on the seedlings`rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.
