Objective To research the changes of calcium regulation hormone and bone mineral density (BMD) in type 2 diabetes mellitus (T2DM ) patients and analyze the main impact factors. Methods 117 T2DM patients (T2DM group ,M/F=52/65 ,age 40~79 years) and 63 age‐ and gender‐matched healthy people (NC group) were selected in this study. According to the course of diabetes ,blood glucose control and the value of BMD ,T2DM patients were divided into subgroups :course≤10 years ,and>10 years ;HbA1 c≤8% ,and>8% ;normal BMD ,osteopenia ,and osteoporosis (OP). Serum 25‐hydroxy vitamin D3 [25(OH)D3 ]and Parathormone (PTH) were measured and BMDs of lumbar spine (L1 ~L4 ) , femoral neck ,total hip ,and whole body were evaluated for all the subjects. Result (1)Compared with NC group ,the level of serum 25(OH)D3 and BMDs of femoral neck and total hip decreased significantly in T2DM group[ (35.57 ± 12.30)nmol/L ,(0.848 ± 0.136)g/cm2 ,(0.873 ± 0.150)g/cm2 vs(44.94 ± 17.40) nmol/L ,(0.927 ± 0.173)g/cm2 ,(0.934 ± 0.140)g/cm2 ,respectively ,P<0.01 or P<0.05)]. The level of PTH increased in T2DM group[ (8.50 ± 4.15) vs(5.62 ± 3.93)pmol/L ,P<0.01]. (2)Compared with the group duration of diabetes≤10 years ,BMD of femoral neck and total hip decreased in patients with duration of diabetes>10 years[ (0.814 ± 0.148) ,(0.840 ± 0.157) vs (0.882 ± 0.111) ,(0.908 ± 0.139) g/cm2 ,respectively ,P<0.05]. The level of PTH increased [(10.55 ± 9.09) vs (7.06 ± 3.74)pmol/L , P<0.05)]. 25(OH)D3 and total body BMD have no significant difference(P>0.05). (3)Compared with HbA1c≤8% group ,BMD of femoral neck and total hip in HbA1c> 8% group decreased [(0.830 ± 0.131) ,(0.832 ± 0.161) vs (0.891 ± 0.130) ,(0.949 ± 0.130)g/cm2 ,respectively ,P<0.05]. The level of PTH increased [(9.96±8.80) vs (7.21±3.98)pmol/L ,P<0.05]. 25(OH)D3and total body BMD have no significant difference(P> 0.05). (4)The rates of OP and osteopenia (41.03% ,47.86% ) in T2DM were higher than those in NC group (26.98% ,33.33% ) (χ2 =4.367 ,4.669 ,P<0.05). The duration of diabetes and the levels of HbA1c and PTH were longer or higher in OP group than those with normal BMD or osteopenia (P<0.05). (5)Logistic regression analysis showed that BMD negatively correlated with the duration of diabetes ,HbA1c ,and PTH (β= 0.076 ,0.213 ,0.112 ,respectively ,P< 0.05) ,and positively correlated with 25(OH)D3 (β= -0.043 ,P<0.05). Conclusion The values of BMD decreased and the incidence of OP is higher in T2DM patients ,particularly in patients with longer diabetic duration and poor glycemic control.

Filamentous fungi have been used in industrial fermentation extensively. Based on non-phosphorylating electron transport process, alternative respiration pathway (ARP) acts as an energy overflow, which can balance carbon metabolism and electron transport, allow the continuance of tricarboxylic acid cycle without the formation of ATP, and permit the turnover of carbon skeletons. Alternative respiration pathway also plays an important role in the stress response of fungi and the physiological function of conditioned pathogen. Alternative oxidase (AOX) is the terminal oxidase responsible for the activity of alternative respiration pathway, which exists widely in higher plants, parts of fungi and algae. Owing to the property that alternative oxidase (AOX) is sensitive to salicylhydroxamic acid (SHAM) and insensitive to conventional inhibitors of cytochrome respiration, alternative respiration pathway by AOX is also named as cyanide-resistant respiration (CRR). In recent years, the study of the alternative respiration pathway and alternative oxidase has been a hot topic in the area involving cellular respiration metabolism. In this review we summarized the latest research advances about the functions of alternative respiration pathway and alternative oxidase in industrial fungi.

Objective To synthesize the hydrophobic supraparamagnetic ironic oxide(SPIO) loaded and hydrophilic SPIO loaded polymeric nano-vesicles and to investigate the feasibility of using hydrophobic SPIO loaded and hydrophilic SPIO loaded polymeric nano-vesicles to display the tumor in MRI in vivo through animal experiments. Methods The polymeric nano-vesicles were prepared from poly (D, L-lactic acid) (PDLLA) and poly (ethylene glycol) (PEG) by a multiple emulsion/solvent evaporation method.The hydrophobic SPIO and hydrophilic SPIO were loaded in the polymeric nano-vesicles respectively.Eighteen nude mice models with human colorectal carcinoma xenograft were established. They were divided equally into three groups (n = 6). The three groups of nude mice models were injected with water-soluble SPIO, hydrophobic SPIO loaded and hydrophilic SPIO loaded vesicle via the mice caudal vein respectively.Dynamic MRI scan were performed in all the mice models. T2WI signal intensity and T2 relaxation time were measured in the tumor, liver and muscle by using T2 mapping software. ANOVA of repeated measurement was used to analyze if there were significant differences of signal intensity changes among the three groups, while Bonferroni method was used for pair-wise comparison. Results On T2 WI, tumors showed decrease in signal intensity after hydrophobic or hydrophilic SPIO loaded polymeric nano-vesicle injection, while no signal intensity decrease was found in the tumor after water-soluble SPIO administration. The maximum percentage of signal intensity decrease in tumor caused by hydrophobic SPIO loaded and hydrophilic SPIO loaded vesicle were 11.00%, 11.40%, respectively. There was statistical significant difference of signal intensity changes among these three groups (F = 10. 96, P < 0. 01). The decrease in signal intensity in the groups with hydrophilic or hydrophobic SPIO loaded polymeric nano-vesicles injection were more pronounced as compared with that of water-soluble SPIO (P < 0. 05), but there was no significant difference in signal intensity decrease between the groups of hydrophilic and hydrophobic SPIO-loaded polymeric vesicles injection (P >0. 05). The three agents could lead to signal intensity decrease in the liver. The maximum percentage of signal intensity decrease in liver caused by water-soluble SPIO, hydrophobic SPIO loaded and hydrophilic SPIO loaded vesicle were 32. 85%, 52. 77%, 56. 89%, respectively. There was statistical significant difference between these groups (F = 161.18, P < 0. 01) . The groups of injecting hydrophilic and hydrophobic SPIO loaded polymeric nano-vesicles had the more obvious signal decrease than the one with water-soluble SPIO (P < 0. 01). Hydrophilic SPIO loaded polymeric nano-vesicles exhibited more signal intensity decrease than hydrophobic SPIO loaded polymeric nano-vesicles (P < 0. 01). All three agents could not lead to T2WI signal decrease in the muscle, and there was no significant difference in signal change on T2 WI among three groups (F = 0. 59, P > 0. 05). Conclusion SPIO loaded polymeric nano-vesicles can cause significant T2WI signal loss in human colonic carcinoma on MR imaging in vivo. It can be used as tumor imaging contrast agents.
