AIM: To evaluate the response of obstructive sleep apnea hypopnea syndrome (OSAHS) to fluoxetine. METHODS: After a baseline polysomnography (PSG) and Epworth Sleepiness Scale (ESS) documented OSAHS, 10 patients were treated with fluoxetine (20 mg?d -1 ) for four weeks, a repeating PSG and ESS was performed to evaluate the action of fluoxetine. RESULTS: After 4 weeks fluoxetine treatment, the proportion of REM sleep time was decreased by 9.2 %, and the assessment of ESS was significantly decreased (P 0.05 ). The apnea/hypopnea index (AHI) fell in average 24.84 per hour,the mean SaO 2 and minimum SaO 2 significantly increased by 3.2 % and 16.6 %, respectively, and desaturation event index significantly decreased 18.24 per hour (P 0.05 ). The treatment efficiency of fluoxetine to OSAHS was 50%. CONCLUSION: Short term use of fluoxetine in patients with OSAHS is associated with better sleep quality, improvement in oxygenation,and reduction of episodic apneas or hypopneas.

Objective To analyze the levels of Th17,CD4+ CDhigh25and the related cytokines (IL-17,IL-21,TGF-β,IL-10)in the plasma of patients with SLE.Methods The percentage of Th17 and CD4+ CDhigh25 Treg cells in peripheral blood were examined by flow cytometry.QRTPCR was used to detect the mRNA expression level of RORγt and Foxp3 of 56 SLE patients (26 patients are inactive and 30 patients are active) and 28 healthy controls.Plasma cytokines levels were measured by ELISA.Results The percentage of Th17 cells in patients with SLE was higher than that of healthy controls [ (3.44 ± 0.96) ％ vs (2.42 ± 0.52) ％,t =5.38,P =0.000 ].The percentage of CD4+ CDhigh25 Treg cells in patients with SLE was lower than that of healthy controls [ ( 1.32 ± 0.57 ) ％ vs ( 2.07 ± 0.67 ) ％,t =3.28,P =0.034].The expressions of RORγt mRNA was increased compared with healthy controls[ (0.219 ±0.063) vs (0.087 ± 0.045 ),t =6.41,P =0.000 ],but the expressions of Foxp3 mRNA was decreased compared with healthy controls [ (0.063 ±0.045) vs (0.128 ±0.056),t =5.28,P =0.000].Plasma levelsof IL-17,IL-21 and IL-10 in SLE patients were 122.4 ( 60.5 - 188.3 ),167.2 ( 128.7 - 871.4 ),51.3(20.9 - 123.7 ) ng/L,respectively,and in the control group were 27.1 ( 18.1 - 86.2 ),31.0 ( 31.0 -424.5),33.5( 16.4 - 54.1 ) ng/L,respectively,they were significantly different between the two groups (Z =3.83,4.54,1.87,all P ＜ 0.05 ).However,TGF-β levels were markedly decreased in SLE patients compared with controls [ 31.0 ( 31.0 - 168.6 ) ng/L vs 159.8 ( 63.4 - 389.7 ) ng/L,Z =4.87,P ＜0.05.IL-17 was positive correlation with Th17 cells,SLEDAI score,dsDNA antibody titers ( r =0.621,0.581,0.512,respectively,all P ＜ 0.05 ),but was negative correlation with C3 ( r =- 0.543,P ＜ 0.05 ) in SLE patients.Although the percentage of CD4 + CDhigh25 Treg cells were negatively correlated with SLEDAI score ( r =- 0.423,P ＜ 0.05 ),it was positively correlated with C3 ( r =0.511,P ＜ 0.05 ).Conclusion This study suggests that the imbalance of Th17 cells and CD4+ CDhigh25 Treg cells and the disorder of related cytokines are important in the pathogenesis of SLE patients.

Objective　This study was to investigate the Chlamydia trachomatis (CT) infection rate in cervical secretion of early pregnant and secondary sterility women. Method　CT-DNA in the cervical secretion of the early pregnant, the secondary sterility, and the control women was detected with polymerase chain reaction (PCR). Results　The infection rates of CT in the early pregnant and secondary sterility women （14.28% and 13.33%）were higher than in the control women (3.33%, P<0.05),and there was no significant difference between the former two groups (P>0.05). Conclusion　There are higher infection rates in the early pregnant and secondary sterility women.Detecting CT and treating in the perinatal period are needed in the early pregnant women who want to be pregnant again.

Objective: To probe into the relationship between integrin β1 expression in human cervical carcinoma HCE1 multicellular spheroids (HCE1/MCS) and their invasion into human umbilical vein endothelium cells (HUVEC), so as to assess the inhibitory effect of anti-integrin β1 monoclonal antibody P5D2 on the invasion of HCE1/MCS into HUVEC. Methods: A model of HUVEC monolayer invaded by HCE1/MCS was established (in brief, the HCE1 invading model). Morphology changes of the HCE1 invading model were observed under inverted microscope and analyzed by Motic Med System after P5D2 treatment. The expressions of β1 integrin on HCE1 monolayer cells, HCE1/MCS, HVUEC monolayer cells, and P5D2-treated HCE1 invading models were measured by immunocytochemistry SABC assay. Results: A HCE1 invading model was successfully established. The HCE1/MCS proliferated rapidly after culture, and on the 7th day the invading area of HCE1/MCS was 40.42 folds larger than the original HCE1/MCS. Invading areas of P5D2-treated HCE1/MCS were significantly smaller than that of the control group after 1, 4, 7 day (P<0.05, or P<0.01), with the invading area after 7 days reduced by (84.68±0.08) % compared with the control group. Integrin β1 expression in HCE1/MCS was significantly higher than that in HCE1 monolayer cells (P<0.01), and the expression was negative in HUVEC. Integrin β1 expression in P5D2-treated HCE1/MCS was significantly lower than that the in untreated HCE1/MCS (P<0.01). Conclusion: Upregulated expression of integrin β1 in HCE1/MCS and HCE1 invading model may be associated with their enhanced adhesion and invasion abilities. Anti-integrin β1 monoclonal antibody P5D2 can partially block the invasion of HCE1/MCS into HUVEC.

Objective Determination of the specific antibodies of IgG and IgM against SARS virus in serum specimens from convalescent SARS patients. Methods The contents of IgG and IgM antibodies against coronavirus were determined with ELISA in the blood of 22 convalescent SARS patients. At the same time, the sera from 22 healthy people were used as negative control. Results The positive rate of specific IgG was 100.0% in convalescent SARS patients (the minimal OD value was 0.477, the maximal OD value was 1.851, the mean value was 1.163), within 71 days of recovery. The positive rate of specific IgM was 22.73% in convalescent patients (5 in 22 samples), and it became negative in all patients after 65 days. On the contrary, the IgG and IgM antibodies were all negative in all 22 healthy people. Conclusion The results indicated that all patients convalescent from SARS could generate specific IgG antibody, which might last for a long time.

Objective To analyze and evaluate the changes of quantity and function of TCBVα24+ Vβ11+ NKT in PBMC of the patients with PBC and its relationship with the occurrence of PBC. Methods Flow cytometry was utilized to count TCRVα24+ Vβ11+ NKT cells in PBMC in 60 cases of PBC and 60 cases of age-matched and gender-matched controls. NKT cells were activated and expanded by α-galcer and IL-2 in vitro. The percentages of positive NKT cells expressing IL-4 and IFN-γ were determined by ICS-FC. The levels of serum IL-4 and IFN-γ were tested by ELSIA. The numbers of cells secreting IFN-γ and IL-4 were detected by ELISpot. Results The ratios of NKT cells in PBC group were [0. 16(0. 11-0. 26) ]% before expansion and [0. 82 (0. 61-0. 89) ]% after expansion, significantly lower than control group [(0.33 (0.27-0.38) ]% and [27.40 (23.52-33.87) ]%, respectively, (Z=6.563, 7.707, P<0. 01 ). Seven days after expansion by α-galcer and IL-2, the expansion folds of NKT cells were 96. 05 (80.50-100.27) in PBC group and 134.65 (121.60-142. 13) in control group, respectively (Z =6.462,P < 0. 01 ). At the same time, the ratio of IFN-γ+ and TCRVα24+ Vβ11+ NKT detected by ICS-FC in PBC group was significantly higher than that in control group [ 38. 98 ( 36.73-42. 98 ) ]% vs [ 34. 56 ( 30. 12-36. 78 ) ] %, Z = 3. 158, P < 0. 05, while the ratio of IL-4+ and TCRVα24 + Vβ11+ NKT cells in PBC group was significantly lower than that in control group[0. 193(0. 179-0. 218) ]% vs [34. 36 (30. 93-38. 77) ]%,Z =6. 476, P <0. 01. The number of IFN-γ SFC detected by ELISpot were [410(380 ~500) ] SFC/1 × 106 PBMC in PBC group and [ 340(280 ~ 390)] SFC/1 × 106 PBMC in control group, respectively (Z = 4. 312, P <0. 05). The levels of serum IFN-γ in PBC group and control group were (67.21 ± 11.27) ng/L and (31.45 ± 8. 17) ng/L, respectively ( t = 27.25, P < 0. 01 ). The level of IFN-γ in PBC group was higher than that of control group. The number of IL-4 SFC were [73(60 ~ 100) ]SFC/1 × 106 PBMC in PBC group vs [245(230 -280) ] SFC/1 × 106 PBMC in control group, Z=5. 112,P <0. 01. The levels of serum IL-4 in PBC group and control group were (12.65 ±4. 17) μ/L and (28.31 ±6.31) μg/L, respectively (t =25.34,P < 0. 01 ). The level of IL-4 in PBC group was lower than that of control group. Conclusions The quantity of TCRVα2.4+ Vβ11+ NKT in PBC group is lower than that in control group. After in vitro activation, the capacity of expansion and producing IL-4 of NKT is decreased in PBC group, while the capacity of producing IFN-γ of NKT is increased in PBC group. The reduction of NKT cells and the immune dysfunction may be one of the important factors in the pathogenesis of PBC.

Objective To explore the CD4 + CD25 + Foxp3 + regulatory T cell percentage and plasma levels of soluble CD25 molecules in peripheral blood of septic patients and their clinical value through prospective study. Method A total of 37 septic patients and 15 non-infectious SIRS patients, who conformed to the criteria of SIRS and sepsis which proposed by American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference ( ACCP/SCCM ) in 1997, were collected in ICU of Ruijin Hospital ( Shanghai Jiaotong University) from February 2009 to February 2010. Twenty-four health people were from Medical Center of Ruijin Hospital, who were excluded infection and (or) autoimmune diseases. There were 26 male and 11 female in sepsis group, average age ( 61.67 ± 11.87 ) years old; 8 male and 7 female in SIRS group, average age (67.06 ± 12.57)years old; 14 male and 10 female in health control, average age (56.54 ± 6.37 )years old. All selected patrents were excluded the autoimmune diseases and (or) patients within recent (30 days) had used or now used immunosuppressive agents. We therefore measured the Treg cell percentage in peripheral blood by Flow Cytometry and the plasma levels of IL-2sRa, IL-4, IFN-γ by ELISA. The data were analyzed by analysis of variance or nonparametric Kruskal-Wallis H test. Results ① The percentage of CD4 + CD25 + Foxp3 + regulatory T cells among septic patients, SIRS patients, and control group was: ( 66.82 ± 21.79 ) %, ( 51.79 ± 21.79 ) %, ( 56.45 ± 10. 68 ) %, respectively. septic patients showed the highest percentages of CD4 + CD25 + Foxp3 + regulatory T cell among CD4 + CD25 + T cells(P ＜ 0.05 ). ② The plasma levels of soluble CD25 in septic patients (425. 619 ± 270.12 ) were significantly higher than SIRS patients (381. 664 ± 189.83) and the control group ( 164. 1 32 ± 56.37 ) ( P ＜ 0.05 ). ③ The correlation analysis between the concentration of soluble CD25 molecules in plasma and the ratio of CD4 + CD25 + Foxp3 + regulatory T cells to CD4 + CD25 + T cells showed Spearman correlation coefficient =0.390, P = 0.003 ( P ＜ 0.05 ). Conclusion: the expression of natural regulatory T cells characteristically increased in septic patients. And the levels of soluble CD25 in peripheral blood were related to the percentages of natural regulatory T cells, which simplified the assessment of the immune status in Septic patients.
