Objective To evaluate the myocardial blood supply in patients with metabolic syndrome (MS) using 99Tcm-MIBI SPECT MPI. Methods A total of 342 patients were divided into four groups according to the number of abnormal metabolic indices: no abnormal metabolic index (Group 1), one abnormal index (Group 2), two abnormal indices (Group 3), three or more abnormal indices (Group 4). Each patient underwent two-day protocol of gated stress and rest 99Tcm-MIBI MPI. One hundred and three of the 342 patients were clinically diagnosed as MS and underwent CAG within 1 month after MPI. χ2test was used to evaluate the difference among the four groups and Kappa test to analyze the correlation between MPI and CAG. Results Compared with CAG, the diagnostic sensitivity, specificity, positive and negative predictive values by 99Tcm-MIBI SPECT MPI for coronary artery diseases (CAD) in 103 MS patients were 80.5% (33/41), 85.5% (53/62), 78.6% (33/42) and 86.9% (53/61), respectively. The correlation coefficient between MPI and CAG was 0.657 (P<0.001). The abnormal MPI rates in group 1, 2, 3 and 4 were 23.3% (10/43), 32.9% (26/79), 54.4% (56/103), and 57.3% (67/117), respectively (χ2=23.22, P<0.001). Conclusions In MS patients,99Tcm-MIBI SPECT MPI can be useful for evaluating myocardial blood supply and the myocardial ischemia rates may correlate positively with the number of abnormal metabolic indices.

Objective To explore a sensitive method and index to evaluate renal functional reserve (RFR) in patients with early diabetic nephropathy (DN) using protein loading-scintirenography.Methods Fifty subjects were studied and divided into 3 groups.Group one (G1) consisted of 14 healthy volunteers;Group two (G2) consisted of 15 patients with type 2 diabetes mellitus (DM) and normoalbuminuria; Group three (G3) consisted of 21 patients with type 2 DM and microalbuminuria.All subjects underwent baseline and protein loading-99 Tcm-DTPA scintirenography within one week.RFR was calculated as the difference between stimulated and baseline glomerular filtration rate (GFR), time of peak ( Tb ), time of half excretion ( C1/2 ), residual rate at 20 min ( C20/b ) .Variance analysis and t-test were used to analyze the group differences.Results ( 1 ) The RFR in terms of GFR had statistical difference between any two groups (t=14.884, 32.180, 16.042, all P＜0.01).After protein-loading, the GFR of G1, G2 and G3 increased 20.1, 10.9 and 2.2 ml·min-1·1.73 m-2 respectively.Therefore, the RFR decreased before microalbuminuria in type 2 DM patients.(2)There was statistical difference between the RFR of G1 and G2 in terms of C1/2 (t = 5.505, P＜0.05 ), and between G1 and G3 ( t = 8.914, P＜0.01 ).(3) There was statistical difference of the RFR in terms of TP between G1 and G3 (t = 5.690, P ＜ 0.01 ).(4) There was statistical difference of the RFR in terms of C20/b between G1 and G3 (t= 4.376, P＜0.05 ).Conclusions 99Tcm-DTPA protein loading-scintirenography is an effective method for measuring RFR to evaluate early DN in type 2 DM patients.

OBJECTIVETo investigate the mechanism underlying the inhibitory effect of tacrolimus (FK506) against acute liver graft rejection.

METHODSRat models of orthotopic liver transplantation were divided into 3 groups, namely the tolerance group with Brown Norway (BN) rats as the donors and Lewis rats as the recipients, rejection group with Lewis rats as donors and BN rats as recipients, and FK506 group with the same donor-recipient pair as in the rejection group and FK506 treatment. The recipients were sacrificed 7 days after the transplantation, and the hepatic histology, cytokine levels, and glucocorticoid-induced tumor necrosis factor-related protein ligand (GITRL) expression in the liver and Kupffer cells were observed and detected.

RESULTSCompared with the tolerance group, the rejection group showed increased GITRL expressions in the liver and Kupffer cells (P<0.05), which was significantly lowered by FK506 treatment (P<0.05). Acute liver graft rejection caused significantly elevated interferon-γ (IFN-γ) levels and decreased interleukin-10 (IL-10) levels in the plasma and Kupffer cells (P<0.05), and these changes were obviously attenuated by FK506 treatment (P<0.05).

CONCLUSIONThe effect of FK506 in suppressing acute liver graft rejection is probably associated with down-regulated GITRL expression in the liver and Kupffer cells.

Objective To investigate the effect of 131I on apoptosis of thyrocytes in patients with Graves disease. Methods Forty-seven patients with Graves disease were divided into two groups, two week group (G2w) and four week group (G4w). All patients underwent thyoid needle biopsy before 131I treatment and the repeated biopsy at two weeks (G2w) or four weeks (G4w) after 131I treatment. The positive units of pro-apoptotic proteins (Fas, FasL) and anti-apoptotic protein (Bcl-2) were studied with immunohistochemistry staining. The differences of the two groups were compared with t-test. Liner correlation analysis was applied to study the correlation between 131I dose and apoptosis-related proteins and that between serum sTSH after 131I treatment and apoptosis-related proteins. Results Fas, FasL and Bcl-2 expression (positive units) were significantly increased in both groups after 131I treatment, G2w :22.84 ± 9.31 vs 16.20 ± 6.75,21.13±6.29vs 14.56±4.06, 21.69±7.83 vs 15.22 ±5.94, t= -3.08, -3.73, -4.05 (allP<0.05); G4w:21.69 ±4.52 vs 15.83 ±5.03, 19. 11 ±3.75 vs 14.02 ±4.98, 19.06 ±3.44 vs 16.63 ±4. 73, t = - 5.26, - 5.00, - 2.41 (all P<0.05). However, no statistical differences were found between G2w and G4w (t = 0. 53, 0. 82, 1.46, all P > 0.05). Significant correlation was found between 131I 0. 727, rFasL = 0. 763 (both P<0.05)), but not between the dose and Bcl-2, rBcl-2 = - 0. 094, 0. 102(both P > 0.05). There were significant correlation between serum sTSH three months after 131I treatment and apoptosis-related proteins, rFas = 0.433, rFasL = 0. 601, rBcln2 = - 0. 397, (all P<0. 05). Conclusions 131I can induce thyrocytes to express the pro-apoptotic proteins in patients with Graves disease.

Methods The epidemiological case data of HIV/AIDS from 2011 to 2014 were collected in Huzhou City by China information system for disease control and prevention.Descriptive epidemiological methods were used for analysis.Results A total of 436 cases with HIV/AIDS were reported during 2011—2014 in Huzhou City,and the number of HIV/AIDS reports increased year by year.The main route of transmission include heterosexual contact,which was accounted for 56.65%.MSM transmission was accounted for 38.53%,and injection drug transmission was accounted for 3.90%.Mother to child transmission was 1 case and blood transfusion /blood products transmission were 3 cases,which accounting for 0.92%.The constituent ratio of injecting drug patients,mother to child transmission or blood transfusion /blood products patients presented declining trend (P <0.05).Patients who were infected through heterosexual contact mainly were 30 to <60 years of age (68.83%),junior middle school or below education level (80.97%),married (61.94%).Patients who were infected through MSMmainly were 15 to <45 years of age (76.19%),high school or higher education (47.62%), unmarried (51.19%),household registration of Huzhou City (52.98%).Patients who were infected through injection
drug mainly were 30 to <45 years of age (70.59%),primary school or lower education level (82.35%),unmarried (47.06%),household registration of other province (94.12%).Most cases were detected HIV positive through clinical tests,which accounting for 51.15%.Most HIV /AIDS of MSM,heterosexual transmission and inject -drugs were distributed in Wu Xing District,which accounting for 67.26%,51.42% and 64.71%,respectively.51.15% HIV /AIDS were detected by clinical test.Conclusion The reported cases of HIV /AIDS were still mainly transmitted by heterosexual contact in recent years in Huzhou City,and the constituent ratio of MSMtransmission has increased slightly.

OBJECTIVETo investigate the effect of solanine on the growth of human prostate cancer cell xenograft in nude mice.

METHODSHuman prostate cancer Du145 cells were injected into the subcutaneous layers on the back of nude mice. After a week, the mice bearing subcutaneous tumor graft were randomly divided into solanine treatment group and saline control group for treatment for 3 weeks. The tumor grafts were then harvested to evaluate the inhibition rate. The mRNA and protein expressions of cell cycle-related genes in the tumors were detected by qRT-PCR and Western blotting, respectively, and tumor cell apoptosis was detected using TUNEL method.

RESULTSThe tumor growth rate in solanine-treated group was significantly slower than that in the control group (P<0.01). The mRNA and protein expressions of C-myc, cyclin D1, cyclin E1, CDK2, CDK4 and CDK6 were significantly inhibited by solanine. Solanine significantly up-regulated p21 mRNA and protein expression in the tumors and induced a higher apoptosis rate of the tumor cells than saline (P<0.01).

CONCLUSIONThe tumor-inhibition effect of solanine is probably mediated by regulating the expressions of genes related with G1/S cell cycle arrest and cell apoptosis.

KAF-200522 and its chloride form, KAF-200522-HCl, were invented in Chemon inc. as new triazole antifungal agents with excellent activities in vivo and in vitro against wide range of fungi. As a result of in vitro susceptibility measurements, 80% minimum inhibitory concentrations (MIC80) of both test articles against Candida albican sp. and Aspergillus fumigatus sp. were below 0.0156 microg/mL, which were over 4,100 times lower than those of fluconazole against fluconazole resistant C. albican sp. and A. fumigatus sp., and were over 16 times lower than those of amphotericin B against above same fungi. Additionally, against representative dermatophytes, Trichophyton sp., the MIC80s of both test articles were below 0.0156 microg/mL which were over 64 times lower than those of fluconazole and amphotericin B. As in vivo antifungal activities in A. fumigatus sp. infected mouse models, KAF-200522 treatment group at 600 mg/kg showed 80% survival rate which was 2 times higher than that of amphotericin B and showed 13.7 days in the mean survival time (MST) which was about 2.1 times higher than that of amphotericin B. But in KAF-200522-HCl treatment groups, all animals were found dead in contrast to 40% survival rate in amphotericin B treatment group, however dose dependent increases in MST was revealed. In conclusion, antifungal activities of KAF-200522 and its mimics, KAF-200522-HCl in vitro and in vivo were confirmed in this study, therefore the potentiality of the present compounds to be developed into new antifungal drug was expected.

OBJECTIVETo evaluate the effectiveness of chemotherapy (CT) and autologous hematopoietic stem cell transplantation (ASCT) as post-remission treatment for adult acute lymphoblastic leukemia (AL) patients.

METHODSSeventy-four ALL patients achieved first complete remission (CR(1)) with induction therapy, and then received early-stage sequential intensive consolidation chemotherapy. After that, 40 patients received chemotherapy (CT group) and 34 received ASCT (ASCT group) as post-remission treatment. The median follow-up was 20.5 months. The rates of leukemia free survival (LFS), overall survival (OS) and relapse were compared between the two groups.

RESULTS(1) The median LFS and OS were 14.0 and 20.6 months respectively for CT group and both were more than 53.5 months for ASCT groups. (2) Relapse occurred in 28 patients (70%) in CT group in a median time of 8.5 months (range, 1-72 months) and 20 of them (71.43%) relapsed within 1 year. Eleven patients (32.35%) relapsed in ASCT group, in a median time of 6 (2-30) months after transplantation. (3) There was no statistic difference in LFS, OS and relapse rate at 1 year between CT and ASCT groups (P > 0.05), whereas both LFS and OS at 3 and 5 years for ASCT group were significantly better than those for CT group (P < 0.05). Relapse rate for ASCT group was lower than that for CT group. (4) Higher LFS and OS and lower relapse rate were found for those who received monoclonal antibody purged autografts followed by immunotherapy and (or) maintenance therapy after ASCT (P < 0.05).

CONCLUSIONSEarly sequential intensive consolidation chemotherapy followed by auto-HSCT could significantly reduce late relapse rate for adult ALL patients, and those received ex vivo purged autografts and immunotherapy and (or) maintenance therapy after ASCT have lower late relapse rate and superior survival.
