Objective To explore the effect of family constellation therapy on the spouses of female tumor patients . Methods Two hundred and two spouses of 202 female tumor patients were divided to the control group ( n = 43 ) and experiment group according to their wills(n=159):the former were intervened with health education and skills training and the latter trained in a workshop with family constellation by psychology training specialists in addition to health intervention and skill training intervention. After the intervention, the two groups were compared in terms of quality of life, family function and marriage status. Result The total scores of the experiment group on quality of life , social relationship and environment were all higher than those of the control group (all P<0.05) and the experiment group got higher score in trusting their spouses than the control group (P<0.05). Conclusion The family constellation can improve female tumor patients'quality of life and promote the trust in their spouses.

Vascular or endoluminal stent is a stent implanted in the lesion site to support stenosis vessels based on luminal balloon expansion,to reduce vascular elasticity recoil and remoulding,and maintain blood flow patent.Some stents can also prevent vascular restenosis.Stent size,surface coverage,radial supporting,extensibility,longitudinal recoil,fatigue test,material composition,corrosion-resistance,coagulation,surface roughness and biocompatibility(blood compatibility) are performance parameters to evaluate the stents.Vascular or endoluminal stent has been widely used in arterial and venous systems and non-vessel luminal systems.The incidence of complications following stenting is 11.6%,including acute or subacute thrombogenesis,restenosis,or stent dislocation.It is commonly demonstrated that intrastent restenosis is caused by hyperblastosis.

Objective To investigate the clinical characteristics of gliomas in children,and assess the value of CT and MRI for diagnosing glioma.Methods Fifty-three children under 14 years old who were admitted into department of neurosurgery of Henan Provincial People's Hospital from Jan.2001 to Dec.2006 were diagnosed as glioma.Their age and sex distribution,clinical symptoms and signs,imaging examinations and pathological examinations were retrospectively analyzed.Results 1.There were 35 males and 18 females.2.The common symptoms and signs were headache and dizziness(32 cases,60.4%),nausea and vomiting(32 cases,60.4%),balance function disorder(31cases,58.5%),episodic convulsion(6 cases,11.3%) and fundus changes(33 cases,62.3%).3.There were 24 gliomas located at supratentorial and 29 gliomas located at infertentorial in this group.4.Thirty-three cases had a CT examination(1 case was wrongly diagnosed) and 28 cases had a MRI examination(all cases were positive);The positive rate of CT for displaying these tumors was 97%,MRI was 100%.5.Pathological examination revealed gliomas in 42 cases after operation.The most common histologically confirmed tumor type reported was astrocytoma,which accounted for 40.5%(17 cases),and the second was medulloblastoma,which accounted for 31.0%(13 cases).Conclusions 1.Glioma are more frequently affected in males than females in children.2.It often occurs in cranial posterior fossa and midline,which causes the symptoms of intracranial hypertension including headache,dizziness,nausea,vomiting,fundus changes,and so on.3.It often occurs in infertentorial,which causes the symptoms of balance function disorder,since it can invade cerebellum directly or indirectly.4.CT and MRI play an important role in the diagnosis of glioma in children.MRI is more valuable than CT in glioma diagnosis.5.Histological types of glioma in children are significantly different from adults.The most common histological types are astrocytoma and medulloblastoma.

Objective To explore the expression of the nuclear factor -κB (NF-κB) regulating monocyte ehemoactracttive peptide -1 ( MCP-1) in asthma patients, and investigate the effect of seretide, budesonide and vento-lin. Methods 81 asthma patients were randomly divided into seretide therapy group and budesonide and ventolin therapy group. The NF-κB activation in PBMC and the plasma concentrations of MCP-1 were measured by ELISA. ventolin therapy group (1.70±0.39) ng/L of asthma patients were significantly higher than that control group (0.89±0.34) ng/L ( P<0.001 ) ; The plasma MCP-1 level in seretide therapy group ( 66.89±5.62 ) ng/L and in budesonide and ventolin therapy group (73.35±7.52 ) ng/L of asthma patients were also significantly higher than level of seretide therapy group in asthma patients were significantly lower than budesonide and ventolin therapy group (P <0.001 ). Conclusion NF-κB gene and its regulating protein MCP-1 may be involved in asthma. Glucocotios-teroid and beta2 agonists combination may prolong the process of asthma.

Lignocellulosic biomass is a promising new source of renewable biofuel that can help reduce reliance on fossil fuels.Researches have been done over the last decades.And considerable progress has been made.The abilities and pathways of natural microorganisms to produce ethanol from cellulose are different.So the researches of reconstructing and recombinating the useful genes from different strains are of great significance to improve the yield of ethanol production and reduce the cost.The characteristics and mechanisms of natural ethanologenic strains and the research progress of constructing recombinant strains was introduced and also analyzed the perspectives and challenges.
