Objective To study influence of psychological intervention on life quality of patients with non-erosive reflux disease(NERD) complicated with depression. Methods Patients with NERD and depression(95 cases) were divided randomly into the observation group(48 cases) and the control group(47 cases).The control group received oral administration of rabeprazole,10 mg,bid.The observation group was given psychological intervention based upon routine medication.Tbe reflux diagnostic questionnaire (RDQ), self-rating depression scale(SDS) and quality of life-index(QL-INDEX) scale were adopted for evaluation before and 8 weeks after treatment. Results The score of SDS was (41.58±6.85) in the observation group,which was lower than that of the control group,(50.42±9.26), after 8 weeks of treatment (P<0.01). The score of QL-INDEX was (8.56±1.38) in the observation group,which was higher than that of the con-trol group,(7.98±1.42), after 8 weeks of treatment (P<0.05). Conclusions Psychological intervention for patients with non-erosive reflux disease (NERD) complicated with depression can ameliorate their de-pression state and improve their life quality.

Objective To investigate the effect of the psychological behavior intervention on the mental status and clinical symptom of patients with functional constipation. Methods All of 78 patients with functional constipation diagnosed by Rome m diagnostic code were randomly divided into study group (n =40) and control group (n = 38). The psychological behavior intervention was used in the study group, the caccagogue and symptomatic treatment was used in the control group. The self-rating anxiety scale(SAS),self-rating depressive scale (SDS) was analyzed and the improving of clinical symptom, adverse effect was compared before and after 4 weeks of treatment respectively. Results The scores of SAS and SDS in the study group significantly decreased after treatment [ (36.25±8.61 )scores vs (42.97±9.25 )scores, P<0.01 ;(38.81±6.53)scores vs (43.36±7.18 )scores ,P < 0.01].There was significant difference between the two groups after treatment (P <0.05).The effective rate of study group was higher than that of control group .(97.50% vs 84.21%,P <0.05). The rate of celiodynia, diarrhea and the recrudescence after the course of treatment in control group was 23.68%, 15.79% and 89.47% respectively, while this numerus in study group was 5.00%,2.50% and 5.00%. Conclusions Psychological behavior intervention plays an important role in the treatment of functional constipation. It can improve the mental status, clinical symptom, and decrease the adverse effect.

Background and purpose:PTEN mutation has been found in 20%-40% of malignant gliomas.The common mutant epidermal growth factor receptor(EGFR vⅢ)was reported to coexpress in PTEN-deficient EGFR-expressing tumor.PTEN has been shown to interact directly with FAK and reduce its tyrosine phosphorylation levels to inhibit cell invasion.The invasion of glioma cells with EGFRvⅢ expression and PTEN deficiency is increased.This study was to observe whether PTEN inhibits glioma cell invasion even in the presence of strong pro-invasive signals provided by constitutive EGFR activity.Methods:U87?EGFR cells were transfected with pcDNA3.1 constructs encoding PTEN and the cells invasion levels were detected by transwell invasion assay.The expression of FAK was detected by immunoblotting.FAK expression vector was transfected into U87?EGFR-wtPTEN cells and the change of cells invasion was documented.Results:PTEN and PTEN(G129E)could inhibit cell invasion induced by EGFRvⅢ.PTEN and PTEN(G129E)could decrease the FAK phosphorylation at Tyr397.Over expression of FAK in U87?EGFR-PTEN abrogated PTEN-induced down-regulation of the phosphorylation status of FAK and rescued cell invasion.Conclusions:PTEN could inhibit cell invasion induced by EGFRvⅢ by dephosphorylating FAK.

Objective To study the treatment of sepsis caused by G - bacteria, anti-lipid A antibodies of bacterial endotoxin were screened from phage antibody library. Methods The mRNA was extracted from human B-lymphocytes against lipid A of bacterial endotoxin, reversely transcripted and amplified by polymerase chain reaction using general primers scanning Fd and light chain of IgG. The amplified fragments were inserted into pCOMB3 vector and electrotransfected competent E.coli XL 1-blue cells. Furthermore, the recombinant phage was lysed by coculture with helper VCSM13. Results Fab displayed on the surface as fusion protein with the N terminal of coat protein Ⅲ, and 4.8?10 6 clone library was established. Antibodies against lipid A of bacterial endotoxin were screened. Specific antibodies against lipid A of bacterial endotoxin were enriched by 100 times after three rounds of panning with lipid A.Conclusions Three clones exhibited specific binding to lipid A is identified by direct and competitive ELISA methods. The succcess of isolating anti-lipid A proves the usefulness of phage display system in human McAb preparation. The result shows that we have got the recombinant phage antibody.

Objective To screen the potent permeation enhancers used in transcutaneous immunization with inactivated highly pathogenic avian influenza vaccine. Methods Five different permeation enhancers, ethanol, propylene glycol, dimethyl sulfoxide, ratinoic acid, oleic acid, were used to treat the skin of BALB/c mice before transcutaneous immunization. Sera were collected before the flist transcutaneous immunization and every two weeks post immunization. The titers of influenza virus-specific humoral IgG and IgA were assayed in serum, lung and nasal lavages by ELISA. The titers of hemagglutination inhibition ( HAI), IFN-γand IL-4 produced by splenic lymphocytes were also detected. Except that, clinical symptom of the skin in different time points and skin pathological changes were observed. Results The serum IgG titers, HAI titers and the influenza virus-specific lgA and IgG in lung and nasal lavages in the groups of HA +CT + DMSO, HA + CT + RA and HA + CT + OA were significantly higher than those of HA and HA + CT groups( P ＜0.05). Moreover, the numbers of splenic lymphocytes producing IFN-γ and IL-4 were increased in the above three groups than those in control groups. In addition, no evident clinical symptoms were observed, but stratum corneum of the skin in different groups showed different changes. Conclusion DMSO,RA and OA are potent permeation enhancers in mouse model inoculated with inactivated high pathogenic avian influenza vaccine transcutaneously.

Objective To study the factors effecting on flow cytometric sperm chromatin structure assay.Methods The SCSA explores the metachromatic properties of acridine orange (AO) and flow cytometry to monitor the susceptibility of sperm chromatin DNA to acid induced denaturation in situ because of the low pH treatment. Results COMP?t, ?t, SD?t value were different upon on the storage methods (①sperm was preserved in 4℃, ②sperm was cryopreservated after dilution ③sperm was cryopreservated). Results show that the second method above made the least artificial injury to sperm DNA. It did not affect the results if the samples were quickly thawed in a 37℃ water bath and detected immediately and the detect current velocity was lower than 300 cell/sec. The intra -CV was 7 28% and the internal CV was 8 92%. Mean and standard deviations of COMP?t were 8 7?11 0% in 511 healthy men. Because data present right skew distribution, the reference range of COMP?t is
