According to seven global minimal essential requirement in medical education laboratory medicine,student practice was tested.The results suggested that laboratory medicine education in China now should increase the courses of communication skills,people’health and hygiene system etc.

Detection of high-risk human papillomavirus ( HPV) gene is essential in cervical cancer screening.This paper presents some HPV detection methods according to different molecular techniques , mainly introducing the commonly used hybird capture Ⅱ, HybriMax and method based on fluorescent quantitative PCR , elaborates their advantages and shortcomings , and discusses the clinical applications in the future.

AIM: To study the effects of acute HIV-1 infection on gene expression in U937 human promonocyte for understanding the pathogenecis of AIDS. METHODS: The expression levels of 550 host cell RNA transcripts in U937 human promonocyte at 2-3 d after HIV-1 infection were assessed using cDNA microarray analysis, and the results were confirmed by semiquantitative RT-PCR. RESULTS: Our results showed that 38 genes were differentially regulated in the infected U937 cells at 2-3 d post infection: 26 genes were down-regulated and 12 genes were up-regulated. These genes encode a host of proteins with divergent functions in a variety of cellular processes including receptor-mediated signaling transduction, subcellular signal trafficking, apoptosis, transcriptional regulation, and chemotaxis. CONCLUSION: HIV-1 infection alters gene expression in U937 human promonocytes.

Objective To study the pathogenesis of Entamoeba gingivalis ( E\^g .) and its relation to periodontal diseases.\ Methods Rats were treated with immuno\|inhibitor for one week and the neck of incisor teeth of the rats was bound with steel wire. They were randomly divided into three groups: the first group was infected by E\^g . in the periodontal tissue, the second group was infected by symbiotic bacteria (s.b.),and the third group was given physiological saline as control.Observation on the periodontal inflammation was made for each group of rats, and the purulent secretion from periodontal abscess was examined for living pathogens.\ Results The incidence of periodontal diseases in rats infected by E\^g . was higher than that of symbiotic bacteria group and that of control ( P

Objective To investigate the value of serum interleukin-6 (IL-6) ,haptoglobin (HPT) and amy-loid A (SAA) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) with pneumonia.Methods 87 cases of acute exacerbation of COPD without pneumonia and 76 cases with pneumo-nia ,admitted in the hospital from December 2015 to March 2017 ,were selected as COPD without pneumonia group and COPD with pneumonia group.62 healthy people who underwent the healthy assessment during the same period were selected as the control group.The changes of serum IL-6 ,HPT and SAA levels in three groups ,the value of serum IL-6 ,HPT and SAA levels in detecting COPD with pneumonia and the correlation of IL-6 ,HPT and SAA were compared.Results COPD patients with serum IL-6 ,HPT and SAA were higher than group COPD with pneumonia group and control group ,and COPD is not associated with serum IL-6 , HPT and SAA in pneumonia group than the control group (P＜0.05) ;IL-6+ HPT+SAA diagnostic specifici-ty ,sensitivity and positive predictive value is higher than IL-6 ,HPT and SAA (P＜0.05) ;IL-6 and HPT was positively related with SAA and HPT was positively correlated with SAA.The serum levels of IL-6 ,HPT and SAA in the COPD with pneumonia group were higher than those in the COPD without pneumonia group and the control group ,and the serum IL-6 ,HPT and SAA levels in the COPD without pneumonia group were higher than those in the control group ,and the difference was statistically significant (P＜0.05).The diagnos-tic specificity ,sensitivity and positive predictive value of the combined detection of IL-6 ,HPT and SAA levels were higher than those of single detection of IL-6 ,HPT and SAA level ,and the difference was statistically sig-nificant (P＜0.05) ;IL-6 level was positively correlated with HPT and SAA levels ,and HPT was positively correlated with SAA level.Conclusion The levels of serum IL-6 ,HPT and SAA in patients with acute exacer- bation of COPD increased.The combined detection of the three had relatively high sensitivity and specificity , and the levels of IL-6 ,HPT and SAA were positively correlated.

OBJECTIVETo explore the clinical features and mutations of MYO5B gene in a family affected with microvillus inclusion disease.

METHODSClinical data of an infant affected with microvillus inclusion disease was collected. Genomic DNA was extracted from peripheral blood samples from the patient and her parents. PCR amplification and Sanger sequencing were performed to analyze all the exons and their flanking sequences of the MYO5B gene.

RESULTSThe patient presented with complicated manifestations including respiratory distress syndrome, dehydration, acidosis, bowel dilatation, liver and kidney dysfunction, and severe and intractable diarrhea. A compound mutation of the MYO5B gene, i.e., IVS37-1G>C/c.2729_2731delC (p.R911Afs916X), was discovered in the patient. The former was a splice-site mutation inherited from the mother, while the latter was a frameshift mutation inherited from the father. Both were not reported previously.

CONCLUSIONBased on the clinical and molecular evidence, the patient was diagnosed with microvillus inclusion disease. Above finding has expanded the mutation spectrum of the MYO5B gene, which can provide valuable information for genetic counseling for the family.
