Scientific research design includes specialty design and statistics design which can be subdivided into experimental design, clinical trial design and survey design. Usually, statistics textbooks introduce the core aspects of experimental design as the three key elements, the four principles and the design types, which run through the whole scientific research design and determine the overall success of the research. This article discusses the principle of randomization, which is one of the four principles, and focuses on the following two issues--the definition and function of randomization and the real life examples which go against the randomization principle, thereby demonstrating that strict adherence to the randomization principle leads to meaningful and valuable scientific research.

Objective:To study the functional status of the monocytes-derived dendritic cells (DCs) plused with HBsAg from patients with chronic hepatitis B and their capacity of inducing the HBV- special cytotoxic T lymphocytes (CTLs),and explore a new method of inducing the special anti-HBV cell-mediated immunity.Methods:Monocytes of patients were isolated from peripheral blood and incubated with GM-CSF+IL-4+TNF-? to induce DCs generation. Those DCs were pulsed with HBsAg to induce HBV- special DCs. The phenotype of DCs including CD1a,CD80,CD83,CD86,CD40 and HLA-DR was characterized by FCM and the stimulating reaction of allogenic T lymphocytes was detected by MTT assay. The concentration of cytokines such as IL-12 and IL-6 in supernate was tested by ELISA and the cytotoxicity of CTLs inducing by the DCs against HepG2 2.2.15 cells,HepG2 cells and K562 cells were detected by LDH assay.Results:The expression of CD1a, CD80, CD83,CD86, CD40, HLA-DR molecules on the DCs pulsed with HBsAg was higher than those of the control group (P

Objective To study the characteristics of mutations of gene COL4A5 encoding type Ⅳ collagen ? 5 chain in one chinese pedigree with X-linked dominant inherited nephritis (Alport's syndrome,AS). Methods Genomic DNA was extracted from 35 members of the pedigree of Alport's syndrome. All of 51 exons of COL4A5 gene were amplified by PCR with the primers synthesized according to the published intron sequences of COL4A5. The PCR products were further analyzed by agarose gel electrophoresis and single strand conformation polymorphism (SSCP). The PCR products showing polymorphism were directly sequenced. Results PCR-SSCP analysis showed that 17 PCR products had abnormal mobility of single strand DNA. DNA sequencing analysis revealed 9 suspicious mutations. But these suspicious mutations were not be confirmed by inverse sequencing analysis. Conclusion The exon mutation of COL4A5 gene of this pedigree did not be found, and the mutations of COL4A5 gene may locate in the its introns.

Objective To investigate and analyze the requirement for health education during and after hospitalizadon of patients with cerebral apoplexy.Methods 150 sober patients with cerebral apoplexy from department of neurology were investigated by questionnaires and the results were analyzed. Results The education content that most patients wanted to understand during hospitalization was treatment method and limbs activity(83.6%and 82.2%);The health education style that they prefered was to communicate directly with doctors and nurses(74.0%);The education content after hospitalization that most patients required was self-nursing knowledge.clinical manifestation and first aid when relapse(90.4%,87.7%and 87.7%).The health education style that they most needed after hospitalization Was that Some reference books would he recommended to them (56.2%).The time choice for health education was consultation whenever they had problems.Conclusion Medical workers should supply selective education and instruction according to the health education requirement and style at different stages of patients with cerebral apoplexy.

Objective To investigate the effects of minute quantity of endogenous endotoxin originating from the lung on ventilator-induced lung injury in rats. Methods Thirty-two pathogen-free male adult SD rats weighing 370-390 g were randomly divided into 4 groups ( n = 8 each): group I spontaneous breathing (group C) ; group Ⅱ spontaneous breathing + IPS (group CL) ; group IE mechanical ventilation (group M) and group IV mechanical ventilation + LPS (group ML). The animals were anesthetized with intraperitoneal 20% urethane 0.8 ml/100 g. Right common carotid artery and left femoral vein were cannulated for BP monitoring and fluid and drug administration. The animals were tracheostomized. In group CL and ML LPS 100μg /kg was instilled into trachea. In group M and ML the animals were mechanically ventilated (V_T 20 ml/kg, PEEP=0, I = E = 1:1). P_(ET) CO_2 was maintained at 35-45 nun Hg by adjusting respiratory rate. The animals were breathing or ventilated with room air,and ECG, BP, HR and P_(ET)CO_2 were continuously monitored. Blood gases were analyzed at the beginning and 1, 2 and 3 h of experiment. The animals were sacrificed at 3 h of experiment. The lungs were removed for microscopic examination. The pathological changes of the lung were scored (0 = normal,3 = severe change) . Wet/dry lung weight ratio was determined. The left lung was lavaged. The broncho-alveolar lavage fluid (BALF) was collected. WBCs in BALF were counted. Pulmonary albumin permeability (PAP) (BALF protein concentration/plasma protein concentration) was determined. Plasma TNF-a and macrophage inflammatory protein 2 (MIP-2) concentrations were detected with ELISA. The endotoxin receptor CD14 mRNA expression in lung tissue was determined by RT-PCR and the macrophage CD14 expression in BALF was determined by immuno histochemistry in group C and M. Results Wet/dry lung weight ratio and PAP were significantly higher in group ML than in group M and C. WBC count in BALF, the pathological score and plasma MIP-2 concentration were significantly higher in group M and ML than in group C and were significantly higher in group ML than in group M. TNF-a concentration was significantly higher in group CL and ML and was not detected in group C and M. CD14mRNA expression in the lung tissue and CD14 expression in BALF macrophage were significantly higher in group M than in group C. Conclusion Minute amount of endogenous endotoxin from the lung can aggravate ventilator-induced lung injury in rats. Mechanical ventilation with large tidal volume sensitizes the lung to LPS stimulation through up-regulation of CD14 exexpression.
