Objective To examine the circulating glucose and body weight in the transgenic MKR mouse model who expressed dominant-negative IGF-1 receptor and insulin receptor in skeletal muscle leading to systemic insulin resistance and diabetes. Methods MKR mice were genotyped by PCR analysis of tail DNA.And in these mice we examined the circulating glucose and body weight once a week from 1 to 16 weeks of age, and the circulating insulin and glucose tolerance at age of two-month-old by using C57 mice as controls. Results The descendents of MKR mice kept hereditary feature. And these mice had hyperglycaemia from 3 weeks of age,and an increasing body weight slowly(P

The cytolytic effect of perforin is a mechanism of anti-virus,killing microbial-infected cells and tumor cells.Perforin is a very important non-specific immune factors in fish.In order to understand the function of perforin,the cDNA of grass carp perforin C-terminal peptide was amplified from grass carp liver and kidney cDNA library.It contains a protein kinase C conserved region 2(C2).The cDNA was connected with pET32a,and transformed to expression bacteria DE3.PFP-C was expressed by a prokaryotic expression system and then purified by affinity chromatography.It showed a significant haemolytic activity when tested with rabbit red cells,the optimal pH for haemolytic activity was 7.5,and its haemolytic function dependents on Ca2+ apparently.

Objective To evaluate the effects of perioperative rehabilitation for patients with self-forearm internal arteriovenous fistula.Methods Divided 124 patients with end-stage renal disease into the functional training group (65 cases,A group)and the control group(59 cases,B group) randomly,and then compared certain related indexes between the two groups.Results In the A group,the artery diametcr was obvious widen before functional training without operation,and the vein diameter was obvious widen before functional training without operation too,P < 0.05.After operation,the A group Anastomotic unobstructed was obviously better than B group in one-stage,P < 0.05.A group with thrombosis cases significantly less postoperative than B group,P < 0.05.A group with edema of hands was significantly shorter than B group,P < 0.01.Postoperative fistula time to maturity in the A group was (43.76 ± 2.21) days,which was significantly shorter than that of in the B group,(49.69 ± 5.85) days,P < 0.01.Conclusion Systematic strengthening of perioperative functional exercises can significantly improve preoperative vascular conditions,improve the success rate of operation,reduce risk of thrombosis cases,shorten the time of hand edema and the time of fistula in mature.

Objective To evaluate the influence of gestational diabetes mellitus (GDM) on maternal and perinatal outcomes in twin pregnancies. Methods We retrospectively analyzed the clinical features of both twin and singleton pregnancies, which delivered in Guangzhou Women and Children's Medical Center between January 1, 2012 and December 31, 2013. The twin pregnancies were divided into two groups:those with (GDM-T, n=51) and without GDM (non-GDM-T, n=130), which were matched by maternal age and delivery time (within one month) in a ratio of 1∶2 among singleton pregnancies with (GDM-S, n=102) and without GDM (non-GDM-S, n=102), respectively. The differences of adverse maternal and perinatal outcomes among these four groups were examined. The overall assessment of pregnancy outcomes was completed using Delphi method. Statistical analysis was performed with one-way analysis of variance, t test, Kruskal-Wallis test, rank test, Chi-square test or Fisher's exact test. Results (1) When compared to GDM-S and non-GDM-S group respectively, less women conceived with the help of assisted reproductive technology, higher proportion of women underwent and gestational age at delivery tend to be earlier in GDM-T and non-GDM-T group (all P<0.01). In oral glucose tolerance test,the fasting blood glucose level of GDM-T group was higher than the other three groups (F=21.716, P<0.01), the glucose levels at 1 and 2 h were higher than non-GDM-T and non-GDM-s respectively (both P<0.01), but no significant difference was found when compared with GDM-S group (P>0.01). Similarly, no significant difference was found in prenatal glycosylated hemoglobin value between GDM-T and GDM-S group (P>0.01). (2) There was no significant difference in the incidences of hypertensive disorders of pregnancy, anemia, premature rupture of membranes, oligohydramnios, placental abruption, postpartum hemorrhage, asphyxia neonatorum, small for gestational age, hypoglycemia of newborn, hyperbilirubinemia of newborn and perinatal death between GDM-T group and the other three groups(all P>0.01). Higher incidences of hypertensive disorders of pregnancy and postpartum hemorrhage were shown in the GDM-T group than in the GDM-S and non-GDM-S groups, respectively (both P<0.01). The incidences of preterm birth in GDM-T and non-GDM-T group were both higher than that in GDM-S and non-GDM-S, respectively [54.9%(66/102), 53.8%(140/260), 5.0%(10/102) and 3.0%(6/102), all P<0.01], while no significant difference was found between GDM-T and non-GDM-T group (P>0.01). (3) The overall assessment of pregnancy outcomes did not show any difference between GDM-T group and the other three groups (χ2=6.707, P>0.01). However, the score for fetal outcomes in the GDM-T group was higher than in the GDM-S and non-GDM-S group, but lower than in non-GDM-T group [M(Q)=1.0(2.3), 0.0(3.0), 0.0(0.0), 1.0(2.8) score, χ2=122.818, P<0.01]. Conclusions GDM does not increase the risk of adverse pregnant outcomes in twin pregnancies.

The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway.

Objective To evaluate the precision of GFR using Gates method and compared with the results from renal pathological changes. Methods Twenty-seven patients whose 99Tcm-DTPA renograms had no obvious uptake phase were enrolled in Group A, and 27 patients whose 99Tcm-DTPA renograms had obvious uptake phase were enrolled in Group B. The measurement of GFR by Gates method was compared to the creatinine clearance measured and predicted by Cockroft-Gault (C-G), modification of diet in renal disease (MDRD) and SCr level. Renal pathological changes in two groups were compared using Pearson correlation and t test analysis. Results In Group A, GFR determined by Gates method did not show correlation with that estimated by C-G or 1/SCr (r = 0. 357,0. 376, both P >0.05), but was significantly correlated with GFR estimated by MDRD(r = 0. 440, P < 0.05). In Group B, GFR determined by Gates method showed significantly correlation among GFR estimated by MDRD, C-G, and 1/SCr (r =0. 471, 0. 527,0. 452, all P < 0.05). Renal tubulointerstitial damage score in Group A was higher than that in Group B (7.15±2.32, 3.70±3.06, t=4.66, P <0.001). Conclusions GFR determined by Gates method is less precise when 99Tcm-DTPA renogram has no obvious uptake phase than that when 99Tcm-DTPA renogram has obvious uptake phase. Renal tubulointerstitial damage is a strong indicator of no obvious uptake phase in 99Tcm-DTPA renogram.
