Diabetic foot is one of the most common and serious complications of diabetes. Early detection and prompt treatment is of great significance to the prevention of diabetic foot. Imaging is the most convenient and effective method for making an early diagnosis of diabetic foot, and imaging examination can directly and accurately reveal the peripheral vascular disorders, peripheral neuropathy, soft tissue complications, muscle and tendon lesions, bone complications, etc. thus the lesion’s extent can be exactly evaluated, which provides reliable basis for the selection and evaluation of the clinical therapeutic scheme. This paper aims to make a general review about the recent imaging research progress in diabetic foot.

Objective To establish carotid artery bifurcation aneurysm in canine, and to clarify whether specific hemodynamic insult in combination with arterial wall degeneration will lead to the occurrence and development of aneurysms. Methods New bifurcation aneurysm model of common carotid artery (CCA) was successfully established in 18 dogs, which were randomly divided into the elastase-treated bifurcation group (EBG,n=9) and the control bifurcation group (CBG,n=9). Three dogs were treated with elastase insult to both straight sections of CCA and were used as elastase-treated straight section group (ESG,n=3). Angiographic and hemodynamic analysis was conducted immediately after the operation, as well as 12 and 24 weeks after the operation. Histopathological examination was performed 12 and 24 weeks after the operation. Results Angiography showed that new aneurysm (mean diameter 3.2 ±0.4 mm) was formed at the apex of CCA bifurcation in 5 dog models of EBG group, while no new aneurysm was observed in both CBG and ESG groups. In EBG group, no rupture of the new aneurysm occurred during the follow-up period. Histological analysis revealed that in EBG group the inner elastic lamina was discontinued, the elastic fiber was disrupted, the muscle layer became thinned, the smooth muscle cells were reduced, and the inflammatory cell (macrophage) infiltration as well as the expressions of MMP-2 and MMP-9 were increased;these changes were statistically significant when compared with those in CBG group and ESG group (P<0.001). Postoperative hemodynamic analysis indicated that in EBG group the wall shear stress at the apex of CCA bifurcation was reduced, the blood flow velocity was decreased, with the relative and total pressure being the highest;all the above changes returned to normal after arterial wall remodeling. Conclusion The results of this study indicate that the arterial wall degeneration and the hemodynamic effect at the apex of CCA bifurcation can lead to new aneurysm formation in canine model.

Objective To investigate the endotoxemia initiated systemic and pulmonary inflammation and acute lung injury in endotoxin tolerant rats MethodsEndotoxi n tolerance (ET) models of SD rats were induced by four daily intraperitoneal in jections of 0 6 mg?kg -1 ?d -1 Escherichia coli LPS (serotype 055:B5).Normal control (NC) rats received intraperitoneal injections of the sa me volume saline On the fifth day,rats were injected with high dose of LPS (6 mg/kg) to induce endotoxemia and lung inflammation Blood,left bronchoalveolar lavage fluid (BALF) and right lung tissue were collected before and 2,6,24,48 ,72 hours after the high dose injection of LPS (six rats for each time point) Cytological examination of blood and BALF and histopathological examination wer e performed Bromine methylphenol green was adopted for measurement of serum alb umin BALF albumin was measured by en z yme-linked immunosorbent assay (ELISA) and adjusted by the ratio to serum album in to evaluate the permeability of pulmonary microvascular Results The symptomes such as less activity,accelerated respiratory rate and weight loss in NC rats was not found in ET rats after the high dose injectio n of LPS BALF albumin as well as the ratio of BALF albumin to serum albumin in c reasedt 2 hours after injection of 6 mg/kg LPS and reached their zenith at 6 hou rs in NC rats,while no increase in ET rats In NC rats the blood white cell dif f erentiating shifted from lymphocyte to PMN,and PMN percentage of BALF also incr eased from (0 443?0 345)% to (8 000?2 896)% with its peak at 24 hours a fter the injection (P

Objective To study the correlation between single point pulse wave velocity (PWVβ)of different peripheral arteries and coronary artery stenosis quantity obtained by coronary arteriongraphy so as to explore the diagnostic value of PWVβin coronary heart disease.Methods We made a retrospective analysis of 183 patients receiving coronary arteriongraphy in our hospital from October 2013 to May 2014.Based on stenosis quantity of coronary artery,the patients were divided into one-vessel lesion group,double-vessel lesion group,multi-vessel lesion group,and nonstenosis as control group.Clinical data of all the patients were collected before coronary arteriongraphy.Different peripheral artery PWVβwas measured with vascular echo tracking (ET)technology for statistical analysis.Results As the lesion vessel number increased,PWVβandβvalues in three peripheral arteries presented a rising tendency.Correlation analysis indicated that PWVβvalues in the three peripheral arteries showed a positive correlation with coronary artery involvement degree.The correlation between PWVβvalue of the common carotid artery and coronary artery involvement degree was most obvious,followed by the femoral artery and the popliteal artery.The sensitivity,specificity,positive predictive value,negative predictive value and Youden index of the common carotid artery PWVβvalue to diagnose coronary heart disease were 91.2%,84.5%,92.7%,81.7 and 0.76,respectively.Non-conditional multi-factor Logistic regression analysis was implemented by choosing age, sex,smoking history,hypertension history,diabetes history,hyperlipemia,BMI,HDL-C,LDL-C,TC,TG,GLU,SBP,DBP,UA,Cr,and PWVβ value as independent variables,and the degree of coronary artery disease as dependent variable.The results revealed that age,hypertension history,diabetes history,and PWVβ value were independent risk factors for coronary heart disease.Conclusion PWVβ value can be regarded as one index for observing artherosclerosis lesion degree and predicting early lesion.PWVβvalue of the common carotid artery can be an important index for dynamically observing the occurrence and development of artherosclerosis.

Therefore this review aims to summarize the meaning, applications, status and influence factors, measurements and training of clinical situation awareness, to provide evidence for training and improving clinical situation awareness.

Objective To assess the clinical value of batroxobin plus aspirin therapy in reducing the incidence of arterial re-stenosis or re-occlusion in diabetic patients with lower-limb ischemia after receiving angioplasty. Methods A total of 110 diabetic patients with symptomatic arterial obstructions were randomly divided into study group (n=50) and control group (n=60). Aspirin 100 mg/d plus batroxobin 5 IU every other day for six times was used in patients of the study group, while only aspirin 100 mg/d was used in patients of the control group. The follow-up finishing point was the end of 12 months. The arterial re-stenosis or re-occlusion was evaluated with magnetic resonance angiography (MRA) and/or vascular sonography. Amputation above the ankle, death, and the cumulative rate of amputation or death were determined, and the limb salvage and survival rates were assessed by using Kaplan-Meier analysis method. Results Twelve months after the treatment, the occurrence of restenosis in the study group and the control groups was 42.8%and 28.9% respectively (P = 0.002). MR angiography and color- duplex sonography revealed that the restenosis occurrence was much higher in infrapopliteal artery (P = 0.003) and in longer (length > 10 cm) diseased artery (P = 0.001). Twelve months after angioplasty Kaplan-Meier analysis showed that the limb salvage-survival rates of the study group and the control group were 78.2%and 93.5%respectively (log-rank test, P = 0.032 4). Conclusion Combination use of batroxobin and aspirin can effectively reduce the occurrence of restenosis after arterial angioplasty, and the clinical effect is particularly better for the artery distal to the knee and the artery with longer lesion (length > 10 cm), besides this treatment can also improve limb salvage rate.

Objective To study the effects of propofol used alone and in combined with opioids in gastroscopy,in order to select the more suitable anesthesia protocol.Methods A total of 285 pa-tients undergoing gastroscopy were selected in April ,201 5 in our hospital,including 105 males,180 females,ranging from 18 to 65 years old,weighing 40-90 kg,falling the category of ASA Ⅰ or Ⅱ. According to random number table,subjects were divided into four groups:dezocine group(group D, n =76),fentanyl group (group F,n =87),oxycodone group (group O,n = 71 )and control group (group C,n =5 1).Each group was implemented the corresponding anesthesia.SBP,DBP,HR,SpO 2 in baseline(T0 ),1(T1 ),3(T2 ),5(T3 )min after entering gastroscope were recorded.Choking cough, body movement,extra propofol,awakening time and inspecting time were observed.Results Among four groups,there was no statistical significance in age,gender,weight,blood pressure,heart rate and oxygen saturation and other general information.There were more cases given extra propofol in group C than in the other three groups (P <0.01 ).While for the experimental groups,there were more cases needing extra propofol in group O than in group D and group F (P < 0.01 ).The incidences of body movement and choking cough in group C were higher than those in the other three groups (P <0.01 ).Compared with the group C,dosage of propofol ,awakening time in the three groups,especially in group D,were much lower (P < 0.01 ).Conclusion Propofol in combination with opioids for sedation during painless gastroscopy can alleviate adverse reaction caused by propofol used alone.The more suitable anesthesia protocol is propofol with dezocine.

A simple and sensitive high performance liquid chromatography with fluorescence detection (HPLC–FD) has been developed for simultaneous quantification of doxorubicin (DOX) and its dipeptide conjugate prodrug (PDOX) in mice plasma. The chromatographic separation was carried out on an Amethyst C18–H column with gradient mobile phase of 0.1%formic acid and 0.1%formic acid in acetonitrile at a flow rate of 1.0 mL/min. The excitation and emission wavelengths were set at 490 and 550 nm, respectively. The method was comprehensively validated. The limits of detection were low up to 5.0 ng/mL for DOX and 25.0 ng/mL for PDOX. And the limits of quantification were low up to 12.5 ng/mL for DOX and 50 ng/mL for PDOX, which were lower than those for most of the current methods. The calibration curves showed good linearity (R2 4 0.999) over the concentration ranges. The extraction recoveries ranged from 84.0%to 88.2% for DOX and from 85.4% to 89.2% for PDOX. Satisfactory intra-day and inter-day precisions were achieved with RSDs less than 9.1%. The results show that the developed HPLC–FD method is accurate, reliable and will be helpful for preclinical pharmacokinetic study of DOX and PDOX.
