The research on the clinical characteristic and epidemiology in Henoch-Schonlein purpara of children indicates that genetic factors are closely connected with the disease and pathological process.In recent years,molecular biology studies show that C1 GALT1 gene,IL gene,vasomotor and endothelial function regulation genes,angiotensin-converting enzyme gene,angiotensinogen gene,MEFV gene and so on,which have aberrant IgAl giycosylation,are closely related with pathogenesis of Henoch-Schonlein purpura in children.The paper reviews the progress of genetic mechanism associated with Henoch-Schonlein purpura in recent years.

As one of the chronic diseases,asthma,plays a serious impact on human daily life.Asthma in children has showed an increasing trend in recent years,but the mechanisms of asthma are not yet clear.Studies have found that store-operated calcium entry(SOCE) plays an important role in the physiological activity of the body.The enhanced SOCE activity can promote cell growth,proliferation,and migration of a variety of cell types.SOCE important molecules STIM1 and ORAI1 may be involved in the asthmatic airway occurrence of hyperresponsiveness and airway remodeling,and closely to the asthmatic development.

In recent studies,it has been demonstrated that the clinical efficacy of surfactant is poor for late protein infants.Besides,this kind of infants have not infection or other risk factors that may lead to respiratory distress syndrome(RDS).Thus,it is speculated that the pathogenesis of RDS of late preterm infants is different from preterm infants.New researches show that,as the key point of Lung fluid transport via Epithelium,α-ENaC plays an important role in the pathogenesis of RDS of late preterm infants through the inhibition of lung fluid clearance and activity of surfactant.This review highlights the most important mechanisms of Lung fluid absorption barrier in RDS of late preterm infants.

BACKGROUND:Diabetes mel itus after kidney transplantation is an important metabolic complication of the transplanted organ, and seriously affects the quality of life and long-term survival rate of patients, which is a risk factor for renal al ograft dysfunction and cardiovascular disease. OBJECTIVE:To investigate the changes in fasting blood glucose and prognosis of patients who had survived more than 1 year after renal transplantation. METHODS:Total y 42 patients undergoing renal transplantation admitted at Xiantao First People’s Hospital from January 2003 to January 2013, including 7 cases of preoperative diabetes, 11 cases of impaired fasting glucose and 24 cases of normal fasting blood glucose. Fasting blood glucose levels were detected at 1, 7, 14 days and 1, 3, 6, 12 months after renal transplantation, and the survival conditions were also compared among different groups. Cox proportional hazard model was used to analyze influential factors of survival in patients undergoing renal transplantation. RESULTS AND CONCLUSION:The fasting blood glucose levels in the diabetes mel itus group were significantly higher than those in the impaired fasting glucose group and normal fasting blood glucose group before and after renal transplantation (P<0.05). The fasting blood glucose levels were increased in al the groups at 1 day after transplantation (P<0.05), and stabilized at 3 months after transplantation. The survival rate was significantly higher in the normal fasting blood glucose group than in the diabetes mel itus and impaired fasting glucose groups after renal transplantation (P<0.05). Cox proportional hazard model analysis showed that preoperative fasting blood glucose, age, postoperative tumor and infection were the independent risk factors for death in patients undergoing renal transplantation, among which, postoperative tumor led to the highest death risk ratio that was 2.376. Taken together, preoperative diabetes mel itus has some impacts on renal recipients who survive more than 1 year fol owing transplantation, but postoperative diabetes mel itus had no influence on the survival rate of the patients.

Vitamin D,an immune regulator,plays an important role in innate immune function of antibacterial peptide.Vitamin D takes part in the innate immune function via toll-like receptor in response to pathogen,then release antibacterial peptide.This study describes the antibacterial peptide constitution and the functions,effection of activeted Vitamin D in innate immune function of antibacterial peptide.

Cytomegalovirus (CMV),a DNA herpusvirusesw,is the most common virus leading to intrauterine infetcion.It is transmitted from mother to fetus through placenta,and the neonates who suffering from congenital symptomatic infections may have sensorineural hearing loss,hepatosplenomegaly,microcephaly,chorioretinitis etc.Studies have suggested that the characters of infections on pregnant women,such as the time of infection,the serological results and virus load in amniotic fluid are associated with the outcome of offsprings.This paper is to review the risk of CMV infections on women at childbearing age,screening of CMV infections on pregnant women and the prenatal diagonosis of fetal CMV infection.

Minimal residual disease(MRD)iS the origin of relapse in leukemia.So it's significant to quantitate MRD in clinical.At present, there are three MRD quantitative assays, such as flow cytometric detection of abnormal immuno-phenotype,polymerase chain reaction(PCR)amplification of antigenreceptor genes and fusion transcripts.Because every measure has its own principle and feature.the clinical applications are different.Selecting suitable assays based on the characteristic of patients can help to quantitate MRD exactly.

Objective To realize current status of healthcare-associated infection (HAI)in a neonatal intensive care unit(NICU)of a hospital,and evaluate the effect of comprehensive intervention measures.Methods HAI in NICU was monitored,targeted intervention measures were implemented,incidence of HAI before and after inter-vention was compared.Results The implementation rates of intervention measures at intervention stage was higher than that of pre-intervention stage,the difference was significant(all P <0.001 ).Incidence of HAI at intervention stage was lower than that of pre-intervention stage(5.64%[46/816]vs 13.45% [46/342],χ2 =20.12,P <0.001). The main infection site was lower respiratory tract (38.04% [35/92]).Incidence of ventilator-associated pneumonia and catheter-related bloodstream infection after intervention were both lower than pre-intervention stage (0.38‰ vs 3.30‰,0.12‰ vs 1 .18‰,respectively).The main isolated pathogens before and after intervention were both gram-positive bacteria,accounting for 58.09% and 51 .16% respectively.Conclusion Routine HAI monitoring can reflect the weak links in infection control practice,HAI can be controlled effectively by carrying out intervention measures.

Objective To investigate the clinical significance of detection of serum IL -6,IL -17, GM-CSF and TNF -αlevels in patients with rheumatoid arthritis.Methods A retrospective research was made in 79 cases with rheumatoid arthritis,and they were divided into stable period and active period,and another 40 healthy persons were chosen as control group.IL -6,IL -17,GM-CSF and TNF -αlevels were compared,and the relevance was investigated.Results CRP,ESR and DAS28 of active period [39.14 (35.81 )mg/L,41.92 (33.27)mg/L, 4.85(2.74)]were higher than those of the stable period[21.07(16.53)mg/L,29.57(25.14)mg/L,2.88(1.76)] and control group[5.92(2.80)mg/L,3.19(2.24)mg/L],the differences were statistically significant (F =7.013, 6.224,2.136,all P <0.05).Serum levels of GM-CSF,IL -6 and TNF -αof active period[33.81(26.97)pg/mL, 47.23(42.81 )pg/mL,75.35 (41.69 )pg/mL]were higher than those of control group [6.19 (5.11 )pg/mL, 4.68(5.21)pg/mL,33.18 (20.94)pg/mL]and stable period [12.81 (9.76 )pg/mL,8.46 (10.37 )pg/mL, 43.05(38.14)pg/mL],the differences were statistically significant (F =5.328,6.117,8.016,all P <0.05).And there was no significant difference in IL -17 level between the groups (F =0.776,P >0.05).No correlation was observed between IL17 and DAS28,GM-CSF and IL -6 (r =0.213,0.167,0.316,all P >0.05),TNF -αand DAS28,GM-CSF,IL -6 and IL -17 (r =0.761,0.729,0.549,0.421,all P <0.05 ),IL -6 and DAS28 and GM-CSF (r =0.648,0.626,all P <0.05),GM-CSF and DAS28 had good correlation (r =0.563,P <0.05). Conclusion IL -6,GM-CSF and TNF -αlevels were positively correlated with the progression of rheumatoid arthritis,joint detection is of great value in monitoring the disease.

Decorin( DCN) is one of the leucine-rich proteoglycan family of small molecules.It is recog-nized as a tumor suppressor gene.DCN can inhibit tumor cell proliferation and metastasis by binding and inactiva-tion of transforming growth factor beta( TGF-β) and inhibiting the expression of vascular endothelial growth fac-tor or by activating the signaling pathway that promotes cell proliferation by EGFR/MAPK/p21.it plays an impor-tant effect on tumor development,angiogenesis and metastasis.DCN is expressed in various malignant tumors,By up or down regulation,DCN can exert its anti tumor activity,as well as reducing or delaying the occurrence and development of many kinds of malignant tumor.DCN gene may be a potential target for the treatment of many kinds of malignant tumors.
