The diabetic patients died of cardiovascular disease mainly. However, the molecular and cellular mechanisms of diabetes complicated with atherosclerosis were still unclear. Endoplasmic reticulum (ER) stress may play a vital intermediate role in the progression of diabetic atherosclerosis. Both of diabetic hyperglycemia induced hexosamine pathway and diabetes induced macrophage insulin resistance can lead to ER stress. The unfolded protein response (UPR) produced by ER stress can be observed throughout the whole development course of atherosclerosis. In addition, ER stress also induced lipid deposition, cell apoptosis and inflammatory response, all of which was important for the progression of atherosclerosis. Though ER stress may be key for diabetes induced atherosclerosis, which pathway played the central role and the interaction between cytokines still need to be investigated. So that we could provide individual therapeutic scheme for treatment as well as prevention of diabetic complication.

Objective: To investigate the effects of steroidal alkaloids and sarcovagine D isolated from Sarcococca hookeriana var. digyna on cell-proliferation and secretion of inflammatory cytokines in TNF-α-induced human RA-FLS MH7A in vitro, and against complete Freund's adjuvant (CFA)-induced arthritis rats in vivo. Methods: CCK-8 assay was utilized to evaluate the anti-proliferation activity in vitro. In in-vivo study, rats were randomly divided into control group, model group (CFA), steroidal alkaloids (STA) groups (5.0, 2.5 and 1.25 g/kg BW), and sarcovagine D (SD) groups (50, 100 and 200 mg/kg BW), 10 rats for each group. To evaluate the anti-inflammation effect, the histology, biochemical parameters and expression of inflammatory cytokines were detected. Results: Steroidal alkaloids and sarcovagine D showed strong anti-proliferative activity during MH7A cell culture proliferation and downregulated NO levels, and inflammatory cytokines (IL-1β, IL-6 and PGE

ObjectiveTo provide anatomy information for harvesting a pedicle or free posterior interosseous artery cutaneous branches-chain flaps. MethodsFourteen forearms from fresh human cadaver were used to study the anatomy characteristics of the posterior interosseous artery cutaneous branches-chain flaps with the following three methods:latex perfusion for microanatomy,denture materials and vinyl chloride mixed packing for cast,and PVA-bismuth oxide perfusion for molybdenum target X-ray arteriography.The cutaneous perforator with a diameter ≥ 0.2 mm were included for statistical analysis.Results① There were 6.2 cutaneous branches raised from posterior interosseous artery. Measuring from the radial edge of ulnar head to the lateral epicondyle of humerus as the standard distance, the distal cutaneous branch clusters located at 21.24％ relative to the standard distance,while the proximal clusters located at 47.86％.② There were two large cutaneous perforators from the posterior interosseous artery at(5.82 ± 1.22)cm proximal to the ulnar styloid and (10.34 ±0.98)cm distal to the epicondyle of humerus.The diameter and pedicle length of the distal perforators were(0.50± 0.04)mm and (16.79 ± 5.12)mm respectively,while the proximal perforator were (0.60 ± 0.08 )mm in diameter with a pedicle (21.20 ± 12.28)mm in length.③ The vascular chains parallel to the posterior interosseous artery were formed via anastomosis of the adjacent cutaneous perforators. ConclusionThere is clinical significance to use pedicle or free posterior interosseous artery cutaneous branches-chain flaps.

OBJECTIVE:To investigate the inhibitory effects mechanism of scallop skirt glycosaminoglycan(SS-GAG)on inju-ry in human umbilical vein endothelium cells (HUVEC). METHODS:In the test,there was a negative control group,a model group and the groups of SS-GAG at high,middle and low concentrations(mass concentrations of 200,100 and 50 mg/L respective-ly). The cells in latter 3 groups were cultured in SS-GAG at different mass concentrations for 12 h,and then in 50 μmol/L oxidized low-density lipoprotein(OX-LDL)for 24 h. MTT method was used to detect cell viability and the activity of lactic dehydrogenase (LDH),the flow cytometer to determine the level of reactive oxygen species (ROS),real-time fluorescence quantitative poly-merase chain reaction (RT-PCR) to detect mRNA expression of lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1), and Western blot to detect NOX4 protein expression. RESULTS:Compared to the cells in the negative control group,those in the model group demonstrated lower viability,higher activity of LDH,higher level of ROS,and stronger expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). Compared to the cells in the model group,those in the groups of SS-GAG at high,middle and low concentrations showed higher viability,lower activity of LDH,lower level of ROS and weaker expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). CONCLUSIONS:SS-GAG can protect HUVEC to some degree by a mechanism which may be related to inhibiting ROS production via LOX-1/NOX4 pathway and relieving oxidative stress injury.
