Objective To explore the correlation between the degree of target vessel occlusion and in-hospital mortality in patients with acute ST-elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). Methods To retrospectively analyze the data collected from the Management System of Cardiovascular Interventional Treatment in Military Hospitals. A total of 8170 patients with STEMI and PCI were enrolled, and the endpoint of present study was in-hospital mortality. The degree of target vessel occlusion were stratified to determine the effects of occlusion degree on in-hospital mortality. Results According to the degree of target vessel occlusion, the enrolled patients were divided into 2 groups: 75%-99% occlusion group and 100% occlusion group. The in-hospital mortality in the 2 groups were 2.2% and 3.0%, respectively (P=0.077). The patients were then further divided into 3 groups according to the symptom-onset-to-balloon time <3h, between 3h and 6h, and ≥6h. The in-hospital mortality in duration <3h group were 2.5% and 3.3%, respectively (P=0.436); duration between 3h and 6h group were 2.0% and 2.9%, respectively (P=0.147); and duration ≥6h group were 2.4% and 2.8%, respectively (P=0.430). Conclusion The in-hospital mortality in STEMI patients may be no relation with the degree of target vessel occlusion. © 2016, People’s Military Medical Press. All rights reserved.

Objective: To investigate the integrated control levels of hemoglobin A1c(HbA1c), systolic and diastolic blood pressure (BP), low-density lipoprotein cholesterol (LDL-C) in retired army cadres suffering from type 2 diabetes (T2DM) in northeast China.Methods: Four hundred and seventy-seven retired army cadres (aged ≥50 years) with T2DM were interviewed using questionnaire. The subjects were assigned into two groups according to the presence (n=350) or without (n=127) cardiovascular disease (CVD), and then the control levels of HbA1c, fast blood glucose (FBG), 2-hour postprandial blood glucose (2hPG), BP, blood cholesterol (TC), triglycide (TG), high-density lipoprotein cholesterol (HDL-C) and LDL-C were compared between the two groups.Results: The overall successful rate of control of HbA1c(<7%) was 65.8%. The overall successful rate of controling HbA1cin diabetic patients without CVD was significantly higher than in those with CVD (74.8% vs 56.9%, χ2=13.857, P<0.05). The overall successful rate for controling LDL-C in enrolled subjects (<2.6mmol/L) was 47.8%. The overall successful rate for controling LDL-C in patients without CVD (<2.6mmol/L) was significantly higher than in those with CVD (<1.8mmol/L) (47.2% vs 23.9%, χ2=6.77, P<0.05). In 85.5% of patients the target of controling blood pressure (<140/80mmHg) was achieved. The successful rates were almost identical between the with- and without-CVD groups (85.1% vs 86.4%, χ2=0155, P>0.05). The comprehensive attainment rate for controling HbA1c, BP and LDL-C among all the subjects was 23.5%, and no significant difference was found between with- and without-CVD subjects (22.9% vs 25.1%, χ2=0.284, P>0.05).Conclusions: Under the military health care management system, the unique and comprehensive successful rate for controling HbA1c, BP and LDL-C was higher among retired army cadres in northeast China as compared with that in non-military Chinese populations, and it is close to, even higher than the reported levels abroad. The successful rate shows no difference between with- or without-CVD subjects. © 2014, People's Military Medical Press. All rights reserved.

Silver nanoparticles (AgNPs) are being used widely and increasingly in various products and medical supplies due to their antibacterial activity. However, little is known about the impacts of the AgNPs. Herein, The primary purpose of this study was to investigate the cytotoxic effect of AgNPs in the human liver cell line (HL-7702). The watersoluble α-Methoxy-poly (ethylene glycol)-ω-mercapto (mPEG-SH)-coated AgNPs (40 nm) were synthesized, which showed superior stabilization and uniform dispersion in culture medium. The effect of mPEG-SH-coated silver nanoparticles on cell viability, leakage of lactate dehydrogenase (LDH), oxidative stress, mitochondrial membrane potential (MMP), and cell cycle was evaluated after the cells were treated with nanoparticles. The results showed that the coated AgNPs could be taken up by cells, decreased cell viability in dose- and time-dependent manners at dosage levels between 6.25 and 100.00 μg/mL, caused membrane damage (LDH leakage), and decreased the activities of superoxide dismutase and glutathione peroxides. The level of malondialdehyde, an end product of lipid peroxidation, was also increased in AgNPsexposed cells. Moreover, flow cytometric analysis showed that AgNP exposure decrease MMP and cause G 2/M phase arrest. Thus, our data suggest that mPEGSH- coated AgNPs have the potential toxicity that is associated with oxidative stress, apoptosis, and DNA damage. © Springer Science+Business Media B.V. 2012.

Surgeons usually use synthetic polymer meshes for abdominal wall hernia repair. However, synthetic polymer meshes exhibit a lack of growth and related complications. In this study, we produced a tissue-engineered patch for abdominal hernia repair. Autologous bone-marrow-derived mesenchymal stem cells (BMSCs) were isolated and proliferated in vitro; decellularized dermal scaffolds (DSs) were prepared using enzymatic process; and then BMSCs were seeded onto the DSs for the construction of tissue-engineered patches. Under general anesthesia, rabbits underwent creation of abdominal wall defects and which were repaired with BMSC-seeded DSs, acellular DSs, and skin sutures only, respectively. Animals were sacrificed after 2 months for assessing the histological and gross examination. Abdominal hernias were absent in animals repaired with cell-seeded group, and abdominal hernias or bulges appeared in all animals repaired with acellular group. All the animals that were not repaired died within 10 days. The cell-seeded implants were thicker and indicated good angiogenesis compared with that of the acellular implants, both in histological and gross examination. The tissue-engineered patches prepared with BMSCs seeding on DSs can be used for abdominal wall hernia repair. © 2011, Copyright the Authors.

Obesity has been reported to be one of the significant contributors to various chronic disease conditions. Childhood obesity has been on an alarming increase over recent years leading to various health complications. Millions of children undergo surgery each year as a part of medical care on various health grounds. In the present study, influence of vitamin C on the effect of obesity and over-weight under anaesthetic exposure was analysed. Separate groups of neonatal mice (C57BL/6) were fed on high-fat diet to induce obesity. The mice were administered with vitamin C at 30 and 60 mg/kg b.wt post natal day 1 (P1) to P21. P7 mice were exposed to equipotent doses of isoflurane or sevoflurane or desflurane. Neuroapoptosis was assessed by measuring activated caspase-3 and TUNEL assay. Plasma S100β levels were detected by ELISA. The mice were assessed for their general behaviour. Morris water maze test was performed to assess the spatial working memory. Anesthesia exposure caused severe neuroapoptosis and also raised the levels of plasma S100β. Neuroapotosis, working memory and learning impairments observed following anesthetics were comparatively more profound on high fat diet fed mice. Desflurane exposure resulted in higher apoptotic counts, learning and memory deficits than equipotent dose of isoflurane and sevoflurane. Vitamin C supplementation offered significant protection against anesthetic induced neurotoxicity and behavioural alterations. Vitamin C administration resulted in marked reduction in neurotoxicity induced by anesthesia and as well improved learning and memory of both normal and high fat diet fed mice. © 2015 E-Century Publishing Corporation.

Objective The article aims at evaluating the biological properties of tibiofibular titanium cable fixation device in terms of both anti-separation and stress shielding by comparison to the interior fixation with lag screw based on experimental observation. Methods Six corpse ankle specimens were first tested of pressure-separation and stress measurement, the data from which were compared to the normal group, and then a syndesmosis injury model was established. All the samples are randomly divided into 2 groups of 3 specimens each, which were treated with tibiofibula locked titanium cable and lag screw fixation respectively for syndesmosis injury. Then, the samples were tested for pressure-separation and stress measurement. The biomechanical properties as anti-separation ability and stress shielding were analyzed and compared between the two fixation method. Results Both tibiofibula locked titanium cables and lag screws were able to provide enough strong lateral anti-separation ability, but strong fixation screws were inferior to tibiofibular titanium cable fixation device in fibular longitudinal stress transduction. Conclusion Tibiofibular titanium cable fixation device not only provide sufficient lateral anti-separation, but also reduces the tibial and fibular longitudinal stress shielding, thus being superior to the traditional lag screw in biomechanical properties. © 2016, People’s Military Medical Press.
