The role of the microvascular disease in progressive renal disease is not well understood .This review presents evidence that progressive renal disease is characterized by a progressive lose of the microvasulature. And presents the factors that induce the lose of the microvasculature. Try to find out (agents) which may represent a novel therpeatic approach for slowing the renal disease.

Gastrointestinal cancers are the most common types of malignant tumors in Human Beings.The main treatment remains surgery resection,in addition to which,adjunctive therapies are far not satisfactory for the target of which are not specific.Dendritic cells cancer vaccine is one of the most promising immunotherapy ways developed in the decades and some results have showed that the vaccines may help in the treatment of gastrointestinal cancers.Till now,there is no recognized standard in the design of the vaccine and no positive correlations between the immunologic effect and clinical prognosis are showed,but we believe that with the further research in the immunological mechanism and the use of new designed methods,dendritic cells cancer vaccines will play a greater role in the treatment of malignant tumors.

Anti-neutrophil cytoplasmic antibodies( ANCA)-associated vasculitis ( AAV) has various clinical symptoms, thus various treatment schemes were used in clinics.To date, there has been no validated diagnostic criteria or treatment guideline for AAV.There are three aspects to be considered when assessing the treatment with AAV patients:staging of disease, distinction between disease activity and chronic damages, and quality of life ( QOL) .This review focuses on the latest classification of vasculitis, the rela-tion between disease stages and its severity, the importance of distinguishing active diseases from permanent damages, the therapeutic choices and the management of complications.

Henoch-Schonlein purpura nephritis(HSPN) is the common secondary glomerulonephritis.Patients with HSPN have various therapeutic reaction and prognosis owing to their varied clinical manifestations or histological changes,and accordingly different therapeutic regimens should be supplied.Patients with severe HSPN should be given active treatment.This article reviews the current treatment of HSPN.

Cytokines may play an important role in the development of IgA Nephropathy(IgAN). In this study, the levels of Interleukin—6(IL—6)activity in the urine and serum from 21 patients with IgAN were measured by using IL—6 dependent cell line, 7TD. IL—6 activities were detectable in both urine and serum in patients with IgAN(IL—6 detectable rate 47.6% and 25% respectively), while it was undetectable in normal volunteers. There was no correlationship between urinary and serum IL—6 activities. Also, we found that patients with elevated urinary IL—6 activity had heavy proteinuria and severe glomerular and tubular—interstitial histological changes. The results suggest that the measurement of IL—6 is useful in evaluating the degree of glomerular and interstitial damage in patients with IgAN.

Objective To study the effects of extract from Narcissus tazetta var. chinensis on proliferation and apoptosis of human multiple myeloma cell line ARH-77. Methods The survival rate of cells were tested by MTT assay when cells were affected by 1.25, 2.5, 5, 10, 20 ?g/mL of the extract for 3 d. After being induced by 10 ?g/mL of the extract for 3 d, apoptotic cells were observed with fluorescence stain; changes of he csll cycle were analyzed by Flow Cytometry; the number and shape of nucleolar organizer region (NOR) were tested by AgNOR assay and submicroscopic structure were observed by transmission electron microscope. Results The extract from N. tazetta var. chinensis could significantly inhibit the proliferation and reduce the survival rate of ARH-77 cells (P

Objective To investigate the clinical characteristics and outcome of the subgroups of class V lupus nephritis (LN) . Methods 152 patients with class V LN proven by renal biopsy were classified into 2 subgroups according to the 1995 WHO modified classification of LN. Class Va (61 patients) referred to pure membranous glomerulonephritis. Class Vb (91 patients) referred to diffuse membranous glomerulonephritis with superimposed mesangial widening and/or mild to moderate hypercellularity, withdeposition of immune complex in the mesangial region. 488 patients with class Ⅳ LN in the same period werechosen as control. The clinical manifestations, serology examination, transformation of histopathological pattern and prognosis were compared between patients with class Va and class Vb. Results The incidence of hypertension, anemia in patients with class Vb were higher than that in class Va significantly (38. 5% vs 21. 3% , 72. 5% vs 52. 5% respectively, P

Objective To analyze the influence of multiple myeloma tumor-associated gene MYEOV2 on NIH/3T3 cells growth. Methods The recombinant plasmid, pcDNA3.1(+)/MYEOV2, was constructed and subsequently transfected into NIH/3T3 cells by liposome. The positive clones of the transfected NIH/3T3 cells were obtained by G418 selection. RT-PCR was used to detecte the expression of MYEOV2 gene in the cells. Fluorescence-activated cell sorting (FACS) and cell grow curve drawing were applied to analyze the influence of MYEOV2 gene on NIH/3T3 cells proliferation. Results The cell clones stably expressing MYEOV2 gene were obtained. FACS analysis showed that the percentage of S phase cell of pcDNA3.1(+)/MYEOV2-transfected cells, pcDNA3.1(+) -transfected cells and non-transfected cells was 30.9%, 20.1% and 16.1%, respectively, and the difference of sphase cell percentage between pcDNA3.1(+)/MYEOV2-transfected cells and the other two groups of cells was significant (P

Objective To investigate the human resources of neurosurgery intensive care unit(NICU)using modified nursing activity score(NAS).Methods NAS was used to investigate the nursing work load of all shifts and compute the needed personnel for every shift,followed by adaption of nursing staff based on the results.Results Based on the scores by NAS,day shift was the heaviest in work load,followed by early night shift and then by late night shift.The differences between day shit and early night shift or late night one were both statistically different(P<0.05 for both).Conclusions The adjustment based on the results by NAS will reduce nursing risk and improve quality of nursing.

Objective To evaluate the effect of type Ⅱ odontoid fracture,type Ⅰ Hangman fracture,C2-C3 disc injury on stability of C1-C2 and C2-C3 segments and investigate the clinical significance.Methods Ten fresh-frozen cadaveric cervical specimens (5 men and 5 women; 25-45 years of age,mean 35.7 years) were selected to test the stability of C1-C2 and C2-C3 segments in the settings of intact condition (control group),type Ⅰ Hangman fracture,type Ⅱ odontoid fracture,type Ⅰ Hangman fracture + type Ⅱ odontoid fracture,type Ⅰ Hangman fracture + type Ⅱ odontoid fracture + C2-C3 disc injury.Range of motion (ROM) and neutral zone (NZ) of those segments were measured.Results Compared with the intact condition,type Ⅰ Hangman fracture produced no significant variations in C1-C2 ROM in all loading modes and C2-C3 ROM during left and right lateral bending; type Ⅱ odontoid fracture produced no significant variations in C2-C3 ROM in all loading modes and C1-C2 ROM during left and right rotation; type Ⅰ Hangman fracture + type Ⅱ odontoid fracture revealed no significant variations in C1-C2 ROM during left and right rotation and C2-C3 ROM during extention; type Ⅰ Hangman fracture + type Ⅱ odontoid fracture + C2-C3 disc injury produced no significant variations in C1-C2 ROM during left and right lateral bending and extension-flextion and C2-C3 ROM in all loading modes (P ＜ 0.05).Conclusions Type Ⅰ Hangman fracture can reserve C1-C2 segmental left and right rotation and extension-flextion; type Ⅱ odontoid fracture can reserve C1-C2 segmental left and right lateral bending and extension-flextion; type Ⅰ Hangman fracture + type Ⅱ odontoid fracture + C2-C3 disc injury can reverse atlantoaxial rotationary stability and C1-C3 segmental stability in all directions.This study provides the biomechanical basis for clinical treatments and the related researches of internal fixation.
