Magnetic resonance imaging (MRI)has apparent dominance in nasopharyngeal carcinoma (NPC) diagnosis,staging,the plan of radiotherapy target and assessment of efficacy because of its high-contrast of parenchyma and muli-parameters imaging.Especially diffusion-weighted imaging (DWI) developed in several years,it can provide qualitative and quantitative information at the cellular level about tumor cellularity and the integrity of cell membranes,which is valuable for tumor detection,cervical lymph nodes metastases,systemic transfer,monitoring and predicting the treatment response of nasopharyngeal carcinoma.

AIM: To investigate the relationship between Alzheimer disease(AD) and alpha 2-macroglobulin(α2M) initially so as to provide evidence for the pathogenesis of late-onset AD.METHODS: The significance of α2M in the late-onset AD was revealed through pathology of α2M in AD and the polymorphism of α2M in AD patients.RESULTS: The association between AD and α2M region on the twelfth chromatosome was analyzed with the genic linkage, and pathological symptom of α2M in AD patients was supported by many evidences. Two polymorphism sites of α2M were located on the 12P12-13, which could increase more risks to AD patients.CONCLUSION: It is significant to investigate the frequency, mutation,polymorphism and expression of gene α2M for the pathogenesis of late-onset AD and its genic diagnosis.

[Objective]This paper will pitch-in TCM psychosomatic theory(from Huangdi Neijing),exploring the disorders of depression with the metabolic syndrome and pathogenesis of traditional Chinese medicine,so as to provide effective ideas for the treatment of depression with metabolic syndrome.[Methods]:Through expansion on traditional chinese medicine's basic understanding of depression with metabolic syndrome,utilizing basic TCM viscera-state theory, from the causes of this disease,key factors,pathogenesis transformation three aspects to discuss the pathogenesis of the disease. [Results]By discussing the heart,liver,spleen function of zang-fu organs and their mutual relations in the role and impact of the disease development process, this paper thinks of the nature of disease as asthenia in origin and asthenia in superficiality,which locates in spleen,has association with heart and liver, phlegm, qi and blood stasis is the disease of pathological product of pathological factors to promote the development of the disease.Kidney would be involved in it with long course of disease.The therapy could focus on tonifying spleen,nourishing heart and soothing liver,with methods of promoting the circulation of qi,removing blood stasis and reducing phlegm,meanwhile looking out to protect kidney.[Conclusion]Disorder of depression and pathogenesis of TCM of metabolic syndrome,to guide the clinical treatment of the disease and the theory of traditional Chinese medicine development has practical significance.

Objective To explore the effects of bed side painless fiberoptic bronchoscopy for bronchoalveolar lavage (BAL) under chest computed tomography (CT) guidance and mechanical ventilation in the patients with severe pulmonary infection (SPI).Methods A total of 131 cases of SPI undermechanical ventilation support were randomly (random number) divided into CT group (C group),chest Xray examination group (X group) and without radiological examination group (N group).The bronchoalveolar lavage (BAL) by using painless fiberoptic bronchoscopy with invasive mechanical ventilation was carried out in patients of these three groups.Vital signs and variables of respiratory mechanics ofpatients were monitored before and 1 h,2 h,and 4 h after BAL and the time consumed for BAL was simultaneous recorded.Meanwhile,infection related biomarkers on the 3rd d and 5thd after BAL,positive detection rate of pathogenic bacteria,the time of invasive mechanical ventilation used during BAL and total duration of mechanical ventilation support were measured.Results During BAL and at 10 min after BAL,heart rate and respiratory rate of C group and X group were lower than those of N group (P ＜ 0.05),however,there was no significant difference in SBP and DBP among groups (P ＞ 0.05).One and two hours after BAL,peak inspiratory pressure (PIP),work of breathing ventilation (WOBvent) and airway resistance (RAW) in C group and X group were lower than those in N group,therefore,dynamic compliance (Cdyn) in C and X groups was better than that in N group (P ＜0.05).Four hours after BAL.Cdyn in C group and X group was better than that in N group (P ＜ 0.05),But there were no significant differences in PIP,WOBvent and RAW among groups (P ＞ 0.05).BAL time (BAL-t) in C group (16.81 ±2.62) min was shorter than that in X group (20.12 ± 3.81) min and N group (23.69 ± 2.76) min,(P ＜ 0.05).Three and five days after BAL,core body temperature,WBC and procalcitonin (PCT) in C and X group were lower than those in N group (P ＜0.05),and those in C group was lower than those in X group (P ＜0.05).Pathogenic micro-organism detection rate in C group (80.55％,29/36) was higher than that in X group (72.09％,31/43) and N group (59.65％,34/57) (P ＜ 0.05).Total mechanical ventilation time (MV-t) in C group (114.36 ± 38.39) h was shorter than that in X group (132.07 ± 42.51) h and N group (165.28 ± 67.28) h (P ＜ 0.05).Conclusions BAL by using painless fiberoptic bronchoscopy under chest CT guidance can effectively reduce the stress on patients with severe pulmonary infection supported with mechanical ventilation,decrease airway hyper-reactivity,shorten the BAL time,ICU stay and duration of mechanical ventilation,facilitate drainage of lung infection exudates and pathogen detection rate and improve efficacy of comprehensive treatment.

In order to study the physiological action of glucocorticoid receptor (GR) in intact animal, an animal model of GR depletion was developed in the rat by mifepristone (RU486), an antagonist of GR. Mifepristone 50 mg/kg body weight mixed in polyvinyl alcohol (PVA) was injected intramuscularly every 12 h in order to maintain the plasma mifepristone at the concentration of about 10-6mol/L for 72 h. In the meanwhile, the plasma corticosterone (B) was stabilized at about 15 ?g/dl by unilateral adrenalectomy 3 d before. In this model mifepristone occupied 88.1 ?10.7% of the total GR in hepatic, brain cytosol and thymocytes as measured by the exchange assay with [3H]dexamethasone (Dex) as ligand. Some indexes of glucocorticoid response were measured in the control, model and bilateral adrenalectomized (AdxT) rats. The polymorphonuclear eosinophil leukocyte (PME) count in blood and phospholipase A2(PLA2) activity in serum were decreased and tyrosine aminotransferase (TAT) activity of the liver was elevated in the control rats after stress provoked by epinephrine, but these changes were reversed in the model rats as well as in the AdxT rats. Thus it may be concluded that decrease of GR to about 12% may result in adrenoglucocorticoid insufficiency in spite of the normal functioning adrenal gland and high plasma level of B. So far as we know this is the first success to produce experimental endocrine insufficiency in a receptor depletion animal model and to quantitate the occupational threshold of about 12% of the total GR in rats.

Dendritic cells (DCs)can capture HIV from the mucosal site and carry it to the draining lymph nodes to promote CD4 + T cell infection.DC-SIGN(CD209)plays a vital role during this process. Heroin,methamphetamine and cocaine are the most abused drugs used by drug abusers,which can increase the opportunities of HIV infection.Drugs acting on the corresponding receptors activate the downstream signaling pathway and regulate the expression of DC-SIGN on the surface of DCs,weakening the inhibited effects of immune cells on HIV and promoting HIV infection in many aspects.Given the multiplex effects of drugs on immune function,this article reviews the relationship between abused drugs,DCs and HIV infection,particularly in the signal pathway on immune modulation.
