BACKGROUND: Severe acute respiratory syndrome (SARS) is caused by a genetically novel coronavirus that is caused by acute infectious disease. It is not yet clear for the immunology function of SARS patients in their convalescent stage.OBJECTIVE: To study the effects on T lymphocyte, and the titer profiling of 24 T cell receptor (TCR) V β subfamilies expressions in SARS convalescent patients.DESIGN: A self-control observation.SETTING: Central Laboratory, Guangdong Provincial Hospital of Traditional Chinese Medicine.PARTICIPANTS: Seventy-six cured SARS patients who received treatment in the Second Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine between January and April 2003. All the patients corresponded to "clinical diagnostic criteria of atypical pneumonia", " diagnostic criteria of severe atypical pneumonia and discharge criteria" and "clinical diagnostic criteria and discharge criteria of severe acute respiratory syndrome". The involved patients, 30 male and 46 female, averaged (32±11 (years old. Another 10 subjects who simultaneously received health examination in the same hospital, 5 male and 5 female, aged (32±7(years, were involved in the study. Informed consents of detected items were obtained from all the subjects.METHODS:①Detecting the expression of 24 T cell receptor(TCR)V β subfamilies in SARS convalescent patients:Peripheral blood(2 mL) was collected from the healthy convalescent subjects,and EDTA-K2 was used as anticoagulant.In the flow cytometry delection tubes.10 μL various fluorescein-labeled mAb,such as anti-CD3,anti-CD4,anti-CD8,anti-CD25,anti-CD28,anti-HLA-DR,anti-CD3mAb conjugated with PC5,TCR Vβ1(PE+FITC).Vβ2(PE+FITC)。Vβ3 (FITC),Vβ4(PE+FITC),Vβ5.1(PE+FITC),Vβ5.2(PE),Vβ5.3(PE),Vβ7.1(PE+FITC),Vβ7.2(FITC),Vβ8(FITC),Vβ9 (PE),Vβ11(PE),Vβ12(FITC),Vβ13.1(PE),Vβ13.2(PE),Vβ13.6(PE+FITC),Vβ14(FITC),Vβ16(FITC),Vβ17 (PE+FITC),Vβ18(PE),Vβ20(FITC),Vβ21.3(FITC),Vβ22(PE+FITC)and Vβ23(PE),was added in special flow tubes,and then 50 μL whole blood was added.The mixed solution was incubated away from light for 15 minutes.After erythrocytolysin being added,mixed solution was washed.Finally.cell deposit was dissolved in 300 μl phosphate buffer solution (PBS).Coulter ESP flow cytometer was used for detection.For the analysis of TCR expression,an electronic gate was set on these cells and at least 5000 events per sample were collected.Three-color cytofluodmetric analysis was performed using a Coulter ESP flow cytometer.②Detecting the T cell subset,activated T and B cells,and the percentage of Ts and Tc cells:5000 cells were collected and used to calculate the expression of T cells (CD3,CD4 and CD8),the activated T and B cells(CD3+/CD25+,CD3+/HLA-DR+ and CD3-/HLA-DR+),as well as the percentage of Ts and Tc cells by Coulter ESP flow cytometer and its software.MAIN OUTCOME MEASURES:①The change of T cell subset(CD3,CD4,and CD8)from SARS convalescent patients.②The change of activated T and B cells(CD3+/CD25+,CD3+/HLA-DR+ and CD3-/HLA-DR+).③The percentage of Ts and Tc cells(CD8+/CD28+,CD8+/CD28-)in convalescent patients.④Analysis of the 24 TCR V β subfamilies from SARS patients in convalescence.RESULTS:All data were explored to analyze the expression profiling of 24 TCR Vβ subfamilies,the data from 74 SARSpatients and 10 healthy controls were explored to other result analysis.①The detecting results of T celI subset:The percentage of CD4+T cell mean value was lower than the reference value[(33.33±6.64)% vs.(43±9)%,P<0.01].The percentage of CD8+T cell mean value was higher than the refefence value[(34.07±6.40)% vs.(30±9)%,P<0.01].② The expression of activated T and B cells:Percentage of HLA-DR+ T and B cell was Increased while the percentage of CD25+ T-cell was decreased compared with reference values.In 53 out of 74 patients,the percentage of CD25+ T cells was lower than the reference value,and 64 patients had a lower percentage in CD3+/CD25+ T cells.The percentages of CD3+/HLA-DR+ and CD3-/HLA-DR+ cells were higher than the normal reference value.T cells expressing higher CD3+/HLA-DR+ were found in 36 patients,and T cells expressing higher CD3-/HLA-DR+ were found in 30 patients.③The ratios of Ts and Tc cells:The percentage of Ts cells which expressed CD8+/CD28- was increased compared with reference value [(28.75±7.31)% vs.(15.99±5.1)%,P<0.01],while the percentage of Tc cells which expressed CD8+/CD28+ was decreased [(5.99±3.60)% vs.(13.2±4.1)%,P<0.01].Thirty-nine patients were found to possess the lower Tc cells and forty-eight patients were found to possess the higher Ts cells.The ratios of both CD4+ and CD8+ T cells were in the normal reference value.④24 TCR Vβ subfamilies expressions in T cells:It was noteworthy that Vβ14 had a highest percentage in all 24 Subfamilies,and followed by Vβ 5.3,and Vβ 23 in the convalescent patients.The percentage of Vβ 14 was the highest in the normal controls,which was consistent with the results of SARS patients.But the other subfamilies expression patterns were different.There were significant differences between Vβ1,Vβ5.2,Vβ5.3,Vβ7.2,Vβ9,Vβ11,Vβ13.1,Vv13.2,Vβ17,Vβ18,Vβ22 and Vβ23.In the convalescent period,each TCR Vβ expression of SARS patients was higher than that of controls(P<0.05-0.01).CONCLUSION:In SARS convalescent patients,the increased CD8+CD28- T cell may elevate CD8+ T cell number;Meanwhile.the reduced CD3+ and CD4+ T cell number may be corresponding to the increased Ts cell number.For some inhibiting factor secreted by Ts cell was also increased.The usage pattern of 24 TCR Vβ subfamilies in SARS patients is different from that of control group.The increase of percentage of CD3+/HLA-DR+ and CD3-/HLA-DR+ T cell may be related to the late response of activated T and B cells.

OBJECTIVE:To study the protective effect of butylphthalide on the apoptosis of human umbilical vein endothelial cells (HUVECs) induced by Aβ1-42 and its mechanism. METHODS:HUVECs were divided into normal control group,Aβ1-42 group,TAK242 group(10 nmol/L),DMSO group(1‰DMSO)and butylphthalide low-concentration,medium-concentration and high-concentration groups (40,80,160 μg/L). Except for normal control group and DMSO group,other groups were given 50 μmol/L Aβ1-42 to culture HUVECs for 24 h. TAK242 group,DMSO group and butylphthalide low-concentration,medium-concentra-tion and high-concentration groups were given relevant concentration of drugs for 30 min,with 3 holes for each concentration. The cell viability was determined by CCK-8 assay;cell apoptosis was observed by Hochest 33342/PI double staining;the cell apoptotic rate was detected by AnnexinⅤ-fluorescein isothiocyanate (FITC) flow cytometry;the protein expression of TLR-4 and COX-2 were determined by Western blot assay;the contents of IL-1 and TNF-α were detected by ELISA. RESULTS:Compared with nor-mal control group,cell viability of HUVECs were decreased in Aβ1-42 group;while apoptotic rate,protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were increased. Compared with Aβ1-42 group,cell viability of HUVECs were increased in TAK242 group and butylphthalide low-concentration,medium-concentration and high-concentration groups;while apoptotic rate, protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were decreased,with statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Butylphthalide can reduce HUVECs apoptosis induced by Aβ1-42,which may be related with inhibiting the expression of TLR4,COX-2 and inflammatory factors.

Objective To observe the inhibitive effect of electro-acupuncture (EA)at Zusanli points (ST36)on inflammatory mediators of postoperative intra-abdominal adhesions and study the relationship between EA and cholinergic anti-inflammatory pathway.Methods Forty-eight male Wistar rats were divided into 6 groups (each =8):Group A (control),Group B(abdominal adhesions model),Group C (abdominal adhesions plus EA),Group D(sham acu-point control),Group E (abdominal adhesions plus α-bungarotoxin )and Group F (abdominal adhesions plus EA after α-bungarotoxin).Animal models of abdominal adhesion were produced by Chiang’s path.Bilateral Zusanli points (ST36) and shame acupoints were electro-acupunctured at a constant voltage for 1 hour while rats were awake.The ɑ-BGT(1 μg/kg)was injected into the abdominal cavity after surgery.All the rats were sacrificed on the 3rd day,and the levels of inflammatory mediators (TNF-ɑ,NO and NOS)in tissues were evaluated.Results Three days after surgery,the damaged cecum of abdominal adhesion groups developed obvious edema that did not adhere with other tissues.Compared with sham control,the abdominal adhesion resulted in significant elevation of inflammatory mediators (TNF-ɑ,NO and NOS).EA at Zusanli points obviously lowered the elevated levels of inflammatory mediators (P <0.01 and P <0.05).EA at Zusanli points following the injection of ɑ-BGT showed less anti-inflammatory effect(P <0.01).Conclusion EA at Zusanli points significantly lowers the elevated levels of inflammatory mediators after abdominal adhesion challenge.The activation of cholinergic anti-inflammatory pathway might be one of the mechanisms by which Zusanli points exert anti-inflammatory effects.

The sfa1 gene encoded a bifunctional enzyme with the activities of both alcohol dehydrogenase and glutathione-dependent formaldehyde dehydrogenase in Saccharomyces cerevisiae.The gene disruption cassette produced by PCR using the same long oligonucleotides which comprise 19 or 22 nucleotides complementary to sequences in the templates(pUG6 and pUG66 marker plasmid)at 3' end and 45 nucleotides at 5' end that annealed to sites upstream or downstream of the genomic target sequence to be deleted.After two linear disruption cassettes with a Cre/loxP mediated marker were transformed into the cells of Saccharomyces cerevisiae YS-1,the positive transformants were checked by PCR to correct the integration of the cassette and concurrent deletion of the chromosomal target sequence.Once correctly integrated into the genome,the select marker can be efficiently rescued by transformating the plasmid pSH47 into YS-1 and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.The expression of the Cre recombinase finally resulted in the removal of the marker gene,leaving behind a single loxP site at the chromosomal locus.The diploid mutant YS-1-sfa1 was generated,which could enhance the output of ethanol with 8.0% by shaking culture in flask compared with the original strain YS-1.
