Objective To analyze the clinical feature of X-linked chronic granulomatous disease (X-CGD) and gene mutation of CYBB. Method The clinical data of X-CGD in one child and the results of CYBB gene detection in his family were reviewed. Results This boy had onset in the neonatal period and presented with recurrent severe pulmonary infection as his main manifestation. Results of nitroblue tetrazolium test (NBT) in both non-stimulation group and LPS stimulation group in the child were 0, and neutrophil oxidation index (NOI) was 1.15. Gene analysis showed a deletion mutation in exon 6 of CYBB gene in the child (579-582delATTA), which resulted in frameshift mutation started from coding sequence of 189—isoleucine (I) and stop codon occured in advance in the 212th amino acid (I189fsX212). Both the child's mother and grandmother were carriers of the mutated gene. The same deletion mutation was not found in the CYBB gene in the amniocyte from the mother's next child. Conclusion One case of X-CGD patient with CYBB gene mutation and his families were diagnosed by gene detection. Prenatal diagnosis can avoid the birth of children with X-CGD.

ObjectiveTo detect the mechanism of the growth inhibition and apoptosis of human acute leukemia cell line U937 cells induced by honokiol.MethedsThe proliferation inhibition was detected by MTT method.Cell apoptosis was tested by Hoechst 33342 staining and flow cytometry with Annexin V/PI staining.RT-PCR was used to detect the mRNA expression of the apoptosis gene Bcl-2,Bax,Caspase 3,Caspase 8 and Caspase 9.ResultsThe inhibition effect of honokiol(5 μg/ml,48 h) on U937 cells proliferation could he observed,and the inhibition rate of 10 μg/ml honokiol on cell proliferation reached above 50％ (48 h).U937 cells proliferation could be completely inhibited for 120 h. U937 cells apoptosis rate reached 26.8％ (P ＜0.01)after being treated with 10 μg/ml honokiol.After being treated with 10 μg/ml honokiol for 48 h,the Bcl-2 gene expression in U937 cells was reduced (control group:0.33 ± 0.02,experimental group:0.14 ±0.01,P ＜ 0.01 ),and the Bax gene expression was elevated ( control group:0.1 ± 0.01,experimental group:0.87 ± 0.08,P ＜ 0.01 ).The gene expressions of Caspase 3 ( control group:0.48 ± 0.01,experimental group:0.87±0.06,P ＜0.01),Caspase 8(control group:0.23±0.02,experimental group:0.41 ±0.07,P ＜ 0.01 ) and Caspase 9 ( control group:0.44 ± 0.05,experimental group:0.76 ± 0.06,P ＜ 0.01 ) were all increased.The activity of Caspase-3 was 0.325 ±0.089,which was significantly higher than that of the control group ( P ＜0.01 ).ConclusionHonokiol can significantly inhibit the proliferation and induce cell apoptosis of human acute leukemia cell line U937 cells.The mechanism is related to the up-regulation of Bax and down-regulation of Bcl-2,and the endogenous and exogenous pathways are both inolved in the apoptosis process.

Objective: To isolate and purify the polysaccharide from Cordyceps sinensis, and analyze its structure. Methods:Cordyceps sinensis was cultured by a liquid fermentation method. A water-extraction and alcohol-precipitation method was applied to ex-tract polysaccharide from Cordyceps sinensis fermentation liquor (EPS) and polysaccharide from Cordyceps sinensis mycelium (IPS). Sephadex gel chromatography was applied to isolate and purify the polysaccharide. The purity and relative molecular weight of the poly-saccharide were determined by a gel filtration method. The monosaccharide composition of the polysaccharide was identified by GC. The content of uronic acid was analyzed by sulfuric acid carbazole method. Results: The analysis results showed that the molecular weight of EPS was 78kDa. The content of polysaccharide and uronic acid was 94. 8% and 6. 0%, respectively. EPS was composed of mannose,glucose and galactose with the molar ratio of 4. 5∶8. 0∶1. 0. The molecular weight of IPS was 42kDa. The content of polysac-charide and uronic acid was 92. 5% and 4. 5%, respectively. IPS was composed of mannose,glucose and galactose with the molar ratio of 2. 8∶3. 0∶1. 0. Conclusion:Both polysaccharide EPS and IPS in Cordyceps sinensis are heteropolysaccharide.

OBJECTIVE: To analyze the impact of extraction and nonextraction in soft tissue profile repair. METHODS: Databases of CNKI, Wanfang, VIP Chinese Periodical Database, CBM, Medline (ovid) and Science direct had been searched for studies of soft tissue profile after orthodontic treatment with and without extractions published in recent decade, with orthodontics, corrective, tooth extraction, soft tissue profile as key words. Hand searching was also done to obtain any further information about the studies. Meta analysis was used to comprehensively quantitatively analyze the upper (lower) lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference (WMD) and 95% confidence interval (95% Cl).Revman 5.0 was used for data management. RESULTS: Five studies with 356 patients were included. Homogeneity test showed that lower lip-esthetic line and lower lip-soft tissue line Ⅰ~2 < 50%, without heterogeneity, so fixed effect model was adopted. Upper lip-esthetic line and upper lip-soft tissue line were more than 50%, indicating heterogeneity, so random effect model was adopted. Result of meta-analysis showed that, the WMD value and 95% Cl of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line has statistically significance. CONCLUSION: The extraction treatment significantly decreased the distance of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line.

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.

Objective To explore the transport properties of the radionuclide strontium 90Sr in the soil-plant system,and discuss the accumulation characteristics of strontiumes in different vegetable tissues.Methods Three kinds of vegetables,including Chinese cabbage,radish and celery,were planted in this experiments using stable nuclide 88Sr instead of 90Sr.Strontium concentrations in these kinds of plant and soil were measured with inductively coupled plasma atomic emission spectrometry (ICP-AES),and the transportation factor (TF) of strontium and the concentration ratio (CR) of these plants were calculated.Results The contents of strontium in different tissues of the vegetables increased significantly in response to the strontium concentrations in soil (F =3.75-139.39,P ＜ 0.05).The contents of strontium at 398.33,477.99 and 557.57 mg/kg in different tissues of these vegetables were significantly higher than that in control group (t =-10.49-7.41,P ＜0.05).Except celery stems,there was a positive correlation about contents of the strontium between other tissues of these vegetables and their experimental soils (r =0.88-0.99,t =7.41-15.96,P ＜0.05).Based on dry weight of examples,the TF in each tissue sample of cabbage and radish was higher than 1,and the concentration ratio,for cabbage and radish,was higher in stems than in roots (F =8.22,91.49,P ＜ 0.05).Conclusions Three kinds of vegetables have been shown to have strontium accumulation ability in soil environment.

Objective To detect the change and clinical significance of homocysteine (Hcy),hypersensitivity C response protein (hs-CRP) and hypersensitivity troponin I (hs-TnI) in patients with acute myocardial infarction (AMI).Methods Ninety-six cases of AMI were selected as the research group and 60 cases of coronary heart disease without AMI were enrolled in the control group.Blood samples were collected to measure the contents of serum Hcy,hs-CRP and hs-TnI.ROC curve was drawn and Logistic regression model was established to analyze the role of each index alone and combined detection in the diagnosis of AMI.Results The levels of Hcy,hs-CRP and hs-TnI in the research group were significantly higher than those in the control group (Hcy: (29.29±7.65) mol/L vs.(17.23±4.68) mol/L;hs-CRP: (15.47±5.01) mg/L vs.(9.21±3.15) mg/L;hs-TnI: (40.88±9.18) ng/mL vs.(7.34±2.12) ng/mL,t=2.78,8.66,34.36,P<0.05).The area under the ROC curve of Hcy,hs-CRP,hs-TnI were 0.802 (95%CI(0.729~0.874)),0.71(95%CI(0.62~0.792)),0.929 (95%CI(0.891~0.967)),respectively.The area under the combine detection curve was 0.971 (95%CI,0.950~0.992).The sensitivity of Hcy,hs-CRP and hs-TnI in the diagnosis of AMI were 79%,57%,87%,respectively,the specificity of the three groups were 72%,70%,90%,the sensitivity and specificity of combined detection were 96% and 88%.Conclusion Combined detection of Hcy,hs-CRP and hs-TnI plays a better role in the diagnosis of AMI than that of Hcy,hs-CRP,hs-TnI alone and has a high specificity and sensitivity in the diagnosis of AMI.

OBJECTIVE To explore the immunity-enhancing effect of ABP-AW1, a low-molecular-mass polysaccharides isolated from Agaricus blazei Murill, on immunosuppressive mice. METHODS ICR mice were ip injected cyclophosphamide 80 mg · kg-1, once daily for 3 d, to establish an immuno?suppressive mouse model. Then, ABP-AW1125, 250 and 500 mg · kg-1 were ig given to the immuno?suppressive mice,respectively, once daily for 7 d. The mouse thymus index and spleen index were calcu?lated, and the phagocytic function of phagocytes was determined using carbon clearance test. Splenic lym?phocyte proliferation was measured by MTT method. The interleukin 2 (IL-2) and interferon γ (IFN-γ) production from splenic lymphocytes was examined by ELISA. The splenic lymphocyte CD4+/CD8+ratio was determined by flow cytometric analysis. RESULTS Compared with normal control group, the thymus index, spleen index and phagocytic index of phagocytes in the immunosuppressive model mice declined (P<0.05). ABP-AW1250 and 500 mg·kg-1 treatment significantly increased the thymus index, spleen index and phagocytic index in immunosuppressive mice (P<0.05). Compared with normal control group, concanavalin A (Con A) and lipopolysaccharide (LPS) induced T and B lymphocyte proliferation, respectively, and IL-2 and IFN-γproduction from splenic lymphocytes in the immunosuppressive model mice was lower (P<0.05). Compared with model group, ABP-AW1250 and 500 mg·kg-1 promoted Con A and LPS induced T and B lymphocyte proliferation (P<0.05) , and elevated IL-2 and IFN-γ production from splenic lymphocytes (P<0.05). In addition, ABP-AW1250 and 500 mg·kg-1 reversed the decreased splenocyte CD4+/CD8+ratio in immunosuppressive model mice (P<0.05). CONCLUSION ABP-AW1 has immuneity-enhancing effect on cyclophosphamide-induced immunosuppressive mice.
