ABSTRACT

Both immunosuppressants and antibiotics (ABX) are indispensable for transplant patients. However, the former increases the risk of new-onset diabetes, whereas the latter impacts intestinal microbiota (IM). It is still unclear whether and how the interaction between immunosuppressants and ABX alters the IM and thus leads to glucose metabolism disorders. This study examined the alterations of glucose and lipid metabolism and IM in mice exposed to tacrolimus (TAC) with or without ABX. We found that ABX further aggravated TAC-induced glucose tolerance and increased insulin secretion. Combined treatment resulted in exacerbated lipid accumulation in the liver. TAC-altered microbial community was further amplified by ABX administration, as characterized by reductions in phylum Firmicutes, family Lachnospiraceae, and genus Coprococcus. Analyses based on the metagenomic profiles revealed that ABX augmented the effect of TAC on microbial metabolic function mostly related to lipid metabolism. The altered components of gut microbiome and predicted microbial functional profiles showed significant correlation with hepatic lipid accumulation and glucose disorders. In conclusion, ABX aggravated the effect of TAC on the microbiome and its metabolic capacities, which might contribute to hepatic lipid accumulation and glucose disorders. These findings suggest that the ABX-altered microbiome can amplify the diabetogenic effect of TAC and could be a novel therapeutic target for patients.

ABSTRACT

Objective To investigate the effect of miR-27a mimic and inhibitor on proliferation and apoptosis in melanoma cell line WM239. Methods The miR-27a mimic,inhibitor and its negative control were transfected into WM239 cells. The transfection efficiency was evaluated by fluorescence microscope. The expres-sion of miR-27a was detected by real-time fluorescent quantitative PCR. The proliferation of cells was detected by MTT. The cell apoptosis and cell cycle were analyzed by flow cytometry. Results The transfection efficiency in WM239 cells was 80% to 90%. The expression of miR-27a was markedly up-regulated in miR-27a mimic group (2-△△CT value is 26. 98 ± 0. 01),with statistically significant difference(t= -1 123. 67,P=0. 00);and the miR-27a inhibitor group showed lower expression of miR-27a(2-△△CT value is 0. 96 ± 0. 02),there was no statisti-cally significant difference compared with normal control group(t=0. 04,P=0. 06). The proliferation of cells was obviously inhibited in miR-27a mimic group,and there was statistically significant difference compared with normal control group[absorbance of 72 h(0. 45 ± 0. 02)∶(0. 72 ± 0. 01),F=129. 56,P﹤0. 05]. The percent-age of WM239 cells in G0-G1 phase was increased[(74. 83 ± 1. 46)∶(63. 73 ± 1. 25),F=30. 33,P﹤0. 05], and the percentage of WM239 cells in S phase and G2-M phase were decreased[(21. 33 ± 1. 75)∶(27. 50 ± 1. 25),F=14. 98,P﹤0. 05;(3. 90 ± 1. 31)∶(8. 80 ± 2. 10),F=3. 66,P﹤0. 05]. The apoptosis rate of cells was significantly increased in miR-27a mimic group compared with normal group[(29. 67 ± 0. 91)%∶(1. 44 ± 0. 85)%,F=530. 90,P﹤0. 01],but the inhibitor group had no obvious effect on cell cycle and cell apoptosis. Conclusion MiR-27a can suppress melanoma cell proliferation and act as a tumor suppressor gene,which is rel-evant to induce cell apoptosis and block cell cycle in G0-G1 phase.

ABSTRACT

Chemokine receptor 4 (CXCR4) belongs to G protein-coupled receptor superfamily.It can induce immune cells-directed chemotaxis,thus keeping their homeostasis.CXCR4 expresses on a variety of tissues and cells.In different tumors and at different stages of tumors,CXCR4 expression is significantly higher than that in normal tissues.CXCR4 plays an important role in tumor progression since it is involved in tumor cell proliferation,adhesion,invasion and metasta.

ABSTRACT

Objective To investigate the effect of early intervention on general movements (GM) in preterm infants during fidgety move-ment. Methods 315 preterm infants during fidgety movement period were divided into intervention group (n=160) and control group (n=155). The intervention group accepted very early intervention program consisted of hospital intervention and family intervention, and the control group accepted routine treatment and nursing. The incidences of different kinds of GMs were compared. Results There is no statisti-cal difference (χ2=0.641, P=0.726) in writhing movement before intervention, and the fidgety movement presented more in the intervention group than in the control group (χ2=8.710, P=0.003), while the absence of fidgety movement was significantly fewer (χ2=5.685, P=0.017) af-ter intervention. Conclusion Very early intervention can reduce the incidence of absence of fidgety movement and improve fidgety move-ment.

ABSTRACT

Objective To determine the changes of peripheral levels of T helper cell cytokines of patients with chronic hepatitis B (CHB) during antiviral treatment,and to further explore its clinical significance.Methods The plasma levels of interleukin (IL)-2,IL-6,IL-10,interferon (IFN)-γ and tumor necrosis factor(TNF)-α of thirty-three CHB patients during antiviral treatment (entecavir) were measured using enzyme linked immunosorbont assay (ELISA).And their biochemical indicators of liver function were determined.The differences of cytokines levels before and after antiviral treatment were compared using ANOVA.The correlations between the changes of cytokines and alanine transaminase (ALT),hepatitis B virus (HBV) DNA levels were analyzed.Results Levels of IFNγ before and 12,24,48 weeks after treatment were (5.98±2.77),(5.95±3.37),(2.93±2.15) and (9.29±4.65) pg/mL,respectively (F=3.845,P<0.05),which were positively correlated with ALT levels (r =0.396,P<0.05).Both TNF-α and IL-10 levels declined after antiviral treatment,which were significantly different at different time points (F=20.156 and 16.695,respectively; both P<0.05),and both levels of TNF-α and IL-10 were positively correlated with ALT levels (r=0.354and 0.316,respectively; both P<0.05) and positively correlated with HBV DNA levels (r=0.382and 0.386,respectively; both P<0.05).While both IL-2 and IL-6 levels were not significantly different between before and after antiviral treatment (F=0.010 and 0.932,respectively; both P>0.05).The serum levels of ALT and HBV DNA before and after antiviral treatment were all significantly different (F=17.69 and 198.98,respectively; both P<0.05),which declined gradually during treatment and were positively correlated (r =0.581,P<0.05).Conclusions IL-10,IFNγand TNF-α may be involved in the pathologic process of CHB,and closely related to the deterioration of the disease.Monitoring plasma levels of these cytokines during antiviral treatment could be useful to understand the immune status and evaluate the efficacy of antiviral drugs.

ABSTRACT

Objective To study the imaging features and the reason of misdiagnosis of multi-nodular bronchioalveolar carcinoma(BAC).Methods 33 cases with the BAC proved by pathology,were reviewed,including 20 males and 13 females,the age ranged from 34~76 years with an average age of 54.2 years.X-ray there were over twice X-ray filmes in all cases,and CT scans with GE 9800 Quick were performed in 30 cases . The imaging features were analysed . Results Imaging findings : Miliary noduli were inhomogeneous in distribution,size and density.The large noduli generally located at the periphery of lung or under the pleura and noduli were focused together,“vacuole sign” was present in 72.7% cases and the noduli were around the vacuole,and lobulated.69.7% of nodule focuses were in company with consolidatory shade . The rate of X-ray misdiagnosis was 75.8%, in which 72.0% were misdiagnosed as TB . CT misdiagnostic rate was 36.4%.The misdiagnostic reasons were unsufficient in consideration of clinical symptom and imaging findings.Conclusion The BAC is the developmental stage of cancer.The accurate diagnosis can be improved if clinical-imaging features are analysed properly,and reexamination and comparison are taken carefully.
