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 compare two different revascularization methods in type 2 diabetes mellitus (T2DM) patients with multivessel coronary artery disease treated by percutaneous coronary intervention (PCI) and coronary artery bypass graft ( CABG) .Methods T2DM patients with multivessel disease undergoing success-ful PCI or CABG were enrolled in the study .They were diagnosed by coronary angiography ( CAG) in Tianjin Chest Hospital from May 2009 to May 2010 whose.The patients were followed up for 3 years.The information of patients including physical performance , clinical features , and laboratory examination results were collected .The major ad-verse cardio cerebral events(MACCE)including death, myocardial infarction(MI), revascularization, angina pecto-ris, heart failure, and stroke were collected.Results During the 3 years of follow-up, MACCE(31.58% vs 17.68%, P<0.01), death(4.82%vs 1.10%, P<0.05), MI(4.39%vs 1.10%, P<0.05), angina pectoris (17.27%vs 10.50%, P<0.05)occurred more frequently in PCI group than in CABG group .Conclusion Evi-dences now tend to support CABG for revascularization in T 2DM patients with multivessel disease .

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 analyze the mean levels of skeletal muscle mass and strength in elderly patients with type 2 diabetes mellitus(T2DM), and to investigate the effects of chronic inflammatory factors and oxidative stress on them.Methods:A cross-sectional study was conducted on 120 patients with T2DM aged over 60 years and 126 elderly patients without diabetes(the control group). Skeletal muscle mass, strength and serum levels of chronic inflammatory factors interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and 8-hydroxy-2′-deoxyguanosine(8-OHdG)were determined, and their effects on skeletal muscle mass and strength in elderly patients with T2DM were analyzed.Results:Compared with the control group, grip strength decreased in elderly patients with T2DM(25.03±7.85)kg vs.(29.52±7.73)kg( P<0.01), and skeletal muscle mass decreased(21.36±5.46)kg vs.(22.01±5.22)kg with no significant difference( P>0.05). Serum levels of 8-OHdG were higher in elderly patients with T2DM than in the control group(3.08±0.26)ng/L vs.(2.59±0.16)ng/L( P<0.01). Correlation and regression analysis results showed that 8-OHdG was an influencing factor for muscle strength in elderly patients with T2DM( R2=0.457)and that height and weight could be influencing factors for skeletal muscle mass in elderly patients with T2DM( R2=0.822). Conclusions:Skeletal muscle mass and strength decline in elderly T2DM patients, probably as a result of increased levels of oxidative stress.These findings may serve as evidence for sarcopenia intervention in elderly T2DM patients.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.
