To observe the regulative effect of applying garlic cream on acupoint Shenque (CV8) on circadian rhythm disorder induced by sleep deprivation.Methods:Twenty healthy adult men were randomly divided into normal group(group A),sleep deprivation group (group B) and treatment group (group C).Subjects in group B and C received 48-hour sleep deprivation,and in the meantime subjects in group C were treated by applying garlic cream on acupoint Shenque(CV8),while subjects in group A received no any treatment,then contents of serum noradrenaline (NA) and 5-hydroxytryptamine (5-HT) were detected.Results:The contents of NA in three groups all appeared typical circadian rhythm(P＜0.01 when group A is compared with group C,and P＜0.05 when group A is compared with group B).The peak value in group A was 158.377 and appeared at 10:56,peak value in group B was 291.529 and appeared at 19:44,peak value in group C was 255.964 and appeared at 17:06.The peak phase in group B shifted more obviously when compared with group A,and the peak phase in group C recovered slightly when compared with group B.The contents of 5-HT in group A showed typical circadian rhythm (P＜0.01) and the circadian rhythms in group B and C disappeared (P＞0.05).the peak value in group A was 196.563 and appeared at about13:10.Conclusion:The application of garlic cream on acupoint Shenque (CV8) Can adjust the disturbed circadian rhythm and accelerate the recovery of circadian rhythm.It is a simple and effective therapeutic method for adjusting circadian rhythm disorder.

Objective To evaluate the effect of peer educatio n program by the application of the peer education on human immunodeficiency vir us/aeguired immune deficiency syndrome(HIV/AIDS) prevention and the analysis of the change on knowledge, attitude and behavior about HIV/AIDS among technical sc hool students in Shanghai. Methods Three technical schools in Shanghai were selected randomly. Two classes of each school were selected randomly as education group and the students added up to 284.Two hundred and sixty-one students of another 2 classes in each school were selected as the interior control group. Some freshmen came from medical un iversity were carefully trained as peer educators to conduct the education inclu ding 6 models. The same questionnaires were carried before and after the educati on in both groups. Results After peer education the score of average knowledge abo ut reproductive health, HIV/AIDS, STD was significantly higher than before (P 0.05). Conclusions The conduction of the peer education on HIV/AIDS pr evention among technical school students is effective in promoting the knowledge level,but the change of attitude and behavior is a long term. So we highly adv ocate that not only the health education for HIV/AIDS especially safe sex shall be given and strengthened among technical school students in order to promote t he notion of self-protection but also the conception of care others especially t he HIV/AIDS.

Objective To observe clinical efficacy of Qilin Pills combined with Three-Spot Caressing in the treatment of acquired non-consolidated kidney qi premature ejaculation (PE). Methods Totally 129 acquired non-consolidated kidney qi PE patients were randomly divided into TCM group, Fangzhognshu group and combination group. TCM group was given Qilin Pills, 6 g each time, three times a day, orally. Fangzhognshu group was guided to conduct Three-spot Caressing during sexual intercourse, no less than twice a week. Combination group was given Qilin Pills and Three-spot Caressing with the same method as Fangzhognshu group. The treatment course for each group lasted for 8 weeks. Before and after treatment of 4 weeks, 8 weeks and 4 weeks after with drawal, the intravaginal ejaculatory latency time (IELT), Chinese Index of Sexual Function for Premature Ejaculation-5 (PECI-5) scores and TCM syndrome scores (TCMS) were compared. Results Compared with before treatment, IELT increased in three groups at different time points after treatment (P<0.05). In the combination group, IELT was superior to the other two groups (except for TCM group after 4-week treatment), with statistical significance (P<0.05). Compared with before treatment, PECI-5 scores improved in three groups (except for Q6 and Q7 in Fangzhongshu group after 4-week treatment) at different time point after treatment (P<0.05). The improvement of Q5, Q6 and Q7 scores in PECI-5 of combination group was significantly better than that in the other two groups at 8-week treatment and 4-week after treatment (P<0.05). Compared with before treatment, TCMS in TCM group and combination group were improved significantly (P<0.05), PE and loss of libido score improved significantly in Fangzhongshu group (P<0.05);mental malaise and move spontaneous perspiration were significantly improved at 8-week treatment and 4 weeks after treatment (P<0.05). The improvement in TCMS was significantly better in combination group than that in the other two groups at 8-week treatment and 4 weeks after treatment (P<0.05). Conclusion Qilin Pills combined with Three-Spot Caressing has definite and long-term efficay for the treatment of acquired non-consolidated kidney qi PE.

ObjectiveTo determine the correlation of human leukocyte antigen-G (HLA-G)expression with CMV active infection after kidney transplantation. MethodsA total of 215 first-time kidney transplantation recipients in one transplantation center were divided into CMV ( + ) group and CMV ( - ) group according to whether they had active CMV infection. mhla-g1 expression on leukocytes was analyzed by flow cytometry. The concentrations of soluble HLA-G5 were detected by using ELISA. The sHLA-G5 cutoff levels by ROC curve was employed to predict the active CMV infection. The expression of sHLA-G5 mRNA and protein in leukocytes was analyzed by using RTPCR and Western blotting respectively. Immunohistochemical staining was used to detect the HLA-G expression in kidney biopsies of 12 cases. ResultsThe expression of mHLA-G1 in peripheral blood was low in both CMV ( + ) group and CMV ( - ) group. Also when CMV-PP65 was positive, there was no significant change in mHLA-G1. In CMV ( + ) group, the proportion of CD14+ mHLA-G1 +cells[(45. 53 ± 17.32)％]in peripheral blood was increased as compared with that in CMV (-)group[(10. 22 ± 5.78)％]. The expression of sHLA-G5 was increased significantly in CMV ( + )group. The optimal cutoff value of sHLA-G5 predicting the active CMV infection was 202. 9 μg/L,with high diagnostic accuracy. HLA-G was positive in the kidney tissue of 10 patients out of 12 patients with active CMV infection. Both RT-PCR and Western blot analysis showed that sHLA-G5 was significantly higher in CMV ( + ) group than that in CMV ( - ) group. ConclusionROC curve analysis of sHLA-G5 with the cutoff value of 202. 9 μg/L can be used to predict the active CMV infection. The HLA-G levels in peripheral blood were significantly increased and HLA-G expression in the tubular epithelial cells of the graft could be a protection mechanism of the kidney function.

Objective To study the correlation of HLA-G levels with acute rejection and CMV active infection post-kidney transplantation.Methods A total of 132 initial kidney transplantation recipients were divided into kidney function stable group (F),acute rejection group (AR),CMV group according to whether they had active CMV infection and acute rejection.Forty-one healthy donors served as control group (H).HLA-G levels and mRNA expression were analyzed by using flow cytometry,ELISA,RT-PCR and Western blotting.Immunohistochemical staining was used to detect the HLA-G expression in kidney biopsies.Results The expression levels of mHLA-G1 were low in all 4 groups pre-transplantation.Only CMV group had significantly more CD14+ mHLA-G1+ cells post-transplantation (P＜0.05).sHLA-G5 levels were higher in F group than in H group (P＜0.05),but there was no significant difference among other groups pre-transplantation (P＞0.05).sHLA-G5 levels were increased significantly in CMV group as compared with F group (P＜0.05),and those in F group were higher than in H and AR groups (P＜0.05).Renal tissue biopsies from 21 renal transplantation recipients with AR indicated that HLA-G5 was expressed negatively in 17 patients,positively in 3 patients and 1 weakly positively.HLA-G was positive in the kidney tissue of 9 patients out of 9 patients with active CMV infection.In total 132 recipients,AR incidence was significantly lower in CMV ( + ) group (7.1 ％,2/28) than that in CMV ( - ) group (24.0 ％,25/104).Conclusion The sHLA-G5 may contribute to predict AR and CMV active infection; AR and CMV active infection may be correlation with immune balance in kidney transplantation recipients.

Objective To obtain colon cancer spheroid cells from human colon cancer cell lines cultured in serum-free medium (SFM),and investigate the proliferative and migratory properties of colon cancer spheroid cells.Methods Human colon cancer cell lines HCT116 and HT29 were cultured in SFM,and then the generation of spheroid cells was observed.The expression of stem cell surface marker CD133 was detected by flow cytometry,and the proliferative and migratory properties of colon cancer spheroid cells were detected by cell counting kit-8 and Transwell migration assay,respectively.All data were analyzed by using the t test.Results Spheroid cells were obtained from colon cancer cell lines HCT116 and HT29 in SFM.The ratios of spheroid cells with positive expression of CD133 generated by HCT116 and HT29 were 75.44％ ± 11.41％ and 76.22％ ± 14.23％,respectively.Compared with original colon cancer cells cultured in serum supplemented medium,the number of HCT116 and HT29 spheroid cells with positive expression of CD133 was significantly greater (t =11.43,9.17,P ＜ 0.05 ),and the proliferative and migratory abilities were much stronger also.Conclusion Colon cancer spheroid cells cultured in SFM have higher positive expression of CD133 and stronger proliferative and migratory abilities,and it can be utilized as a feasible model for further studies of colonic stem cells.

ObjectiveTo assess the relationship between the estimated glomerular filtration rate (eGFR) and the severity of coronary artery stenosis in elder people. MethodsSix hundred and fifty-seven patients who underwent selective coronary artery angiography were divided into 3 groups according to age: group Ⅰ (202 patients aged <60 years), group Ⅱ (181 patients aged from 60 to 69 years) and group Ⅲ (274 patients aged ≥70 years). According to the simplified MDRD equation,impaired renal function and severe renal dysfunction, respectively. Clinical features and the severity of coronary artery stenosis were compared among the 3 groups. ResultsThe level of average eGFR tended to he decreased with the narrowed coronary arteries. The difference of average eGFR between patients with muhivessel versus two-vessel coronary artery disease was of statistical significance in Group Ⅲ(P = 0. 035). After controlling for the effects of smoking, hypertension, dyslipidemia,aging, and diabetes, the Gensini score which reflected the severity of coronary artery stenosis was negatively correlated with the level of eGFR (r =-0. 110, P = 0. 005). ConclusionsIt suggests that the eGFR decrease is associated with the severity of coronary artery stenosis, and there is a linear correlation between eGFR and Gensini score in elder people, eGFR can be used to evaluate the severity of coronary artery disease and prognosis.

Objective To measure the cytokines levels in peripheral blood from kidney transplantation recipients by using cytometric bead array and to analyze their change and the clinical significance in pre- and post- kidney transplantation, inducting with basiliximab and graft rejection. Methods A total of 72 renal transplantation recipients were divided into two groups, kidney function stable group(n =53) and acute rejection group (n = 19). And they were also grouped by induction with basiliximab or not,32 in basiliximab group and 40 in without basilixmab group. The levels of IFN-γ, TNF-α, IL-10, IL-5,IL-4, IL-2 were measured by cytometric bead array in peripheral blood of 72 kidney transplantation recipients and 30 healthy donors at differential time. The data was analyzed according to the following grouping:donors and recipients, kidney function stable group and acute rejection group post transplantation and with or without basiliximab group. Results The levels of TNF-α, IL-10, IL-5, IL-4, IL-2 in recipients before transplantation were ( 1.65 ±0. 10) ,(2. 55 ±0. 19) ,( 1.88 ±0. 14) ,(1.85 ±0. 12) ,(2. 12 ±0. 09) ng/L,respectively. While they were (3.04 ±0. 17), (3.33 ±0. 26), (4.03 ±0.25), (2.73 ±0. 16), (4.03 ±0. 26) ng/L respectively in healthy donors. There was statistical significance between the two groups ( t =6. 890, 2. 375, 7. 851,3.955,7.153, P<0. 01, <0. 05, <0.01, <0.01, <0.01). While the level of IFN-γ in recipients before transplantation was (2. 50 ±0. 18) ng/L,compared with (3. 00 ±0. 24) ng/L in healthy donors. There was no statistical significance between the two groups( t = 1. 625, P > 0. 05 ). The levels of IFN-γ and IL-10 in kidney function stable group were (2. 71 ± 0. 11 ) ng/L and (3.91 ± 0. 52) ng/L,while they were ( 3.30 ± 0. 36 ) ng/L and ( 12. 01 ± 5.35 ) ng/L in acute rejection group. There were statistical dirrerences between the two groups ( t = 5. 061, 11. 465, P < 0. 01, < 0. 05 ). Before induction with basiliximab, the levels of IFN-γ, TNF-α, IL-10 in recipients were (2.90 ±0. 21 ), ( 1.67 ±0. 12),(2. 45 ± 0. 16) ng/L respectively. But they were ( 2. 78 ± 0. 17 ), ( 1.58 ± 0. 07 ), ( 2. 77 ± 0. 24 ) ng/L respectively after induction with basiliximab, which showed significantly different ( t = 5. 605, 6.011,4. 126, P <0. 01, <0. 01, <0. 05). Four weeks after kidney transplantation in recipients with basiliximab,the levels of IFN-γ, IL-10, IL-4 were (2. 90 ± 0. 31 ), (9. 08 ± 0. 16), (2. 73 ± 0. 11 ) ng/L. While they were (3.28 ±0. 11 ), (4. 17 ±0. 21 ), (2. 11 ±0. 20) ng/L respectively in recipients without basiliximab induction, which were significantly different from those with basiliximab induction (t = 4. 268,4. 263,3.762, P <0. 01, <0. 01, < 0. 05 ). Conclusions Six kinds of cytokines can be measured by cytometric bead array simultaneously and accurately. The data suggests that the detection of multiple cytokines in kidney transplantation recipients by cytometric bead array can provide more guidance for clinical diagnosis and therapy.
