Objective To analyze the relationship between carotid intima-media thickness (CIMT) and metabolic syn?drome (MS), and explore risk factors for CIMT incrassation in Tianjin policemen. Methods Fifty MS patients (MS group) and 50 healthy people (control group) in health examination of Tianjin policemen were enrolled in this study. The question?naire survey(family history,past medical history,present history,living habits and occupational stress factors) were recorded in two groups of patients. The blood indicators (fasting plasma glucose, triglycerides, total cholesterol, high density lipopro?tein cholesterol, low density lipoprotein cholesterol, homocysteine) were detected. The color Doppler was used to measure CIMT incrassation, and incrassation ratio was calculated. The relative indicators were compared between two groups. The lo?gistic regression model was used to analyse the influencing factors of carotid artery intima-media thickness. Results CIMT and CIMT incrassation ratio (communis, internal and external carotid) were significantly higher in MS group than those of control group (P<0.01). The risk factors for CIMT included family history of hypertension, chronic stress, smoking, family history of diabetes, high fat diet and high homocysteine levels, and dairy products were protective factors for CIMT incrassa?tion. Conclusion The reason of carotid artery intima-media thickness is diversity. The healthy lifestyle and clinical inter?vention to retard CIMT are advocate, which are conducive to the control of atherosclerosis.

Objective To explore the effectiveness of long-acting antibacterial material that was used as an intervention in oral care cavity nursing in patients with endotracheal intubation and mechanical ventilation. Methods Patients admitted to Xuzhou Medical College Hospital neurosurgery intensive care unit between 1st December 2013 and 31st August 2014 requiring intubation and mechanical ventilation were enrolled into the study. There were 100 cases randomly selected and were assigned into control group and experimental group by random number table. Each contained 50 cases. Control group used saline for oral care by brushing and irrigation;experimental group used antimicrobial material oral spray in oral care on the top of the method used in control group. The mouth odor, mouth infection rate and ventilator-associated pneumonia (VAP) rate were used to determine. Results About oral odor, mouth infection rate, and VAP rate, the difference of incidences between experimental group and the control group was significant (χ2=4.504-13.728, P <0.05). Conclusions Antimicrobial material can effectively improve oral health in intubated and mechanical ventilated patients. It slows oral acidic environment change, reduces oral infections early onset VAP incidence. And it is worth promoting its use.

To investigate cytotoxic secondary metabolites of Micrococcus sp. R21, an actinomycete isolated from a deep-sea sediment (-6 310 m; 142 degrees 19. 9' E, 10 degrees 54. 6' N) of the Western Pacific Ocean, column chromatography was introduced over silica gel, ODS, and Sephadex LH-20. As a result, eight compounds were obtained. By mainly detailed analysis of the NMR data, their structures were elucidated as cyclo(4-hydroxy-L-Pro-L-leu) (1), cyclo(L-Pro-L-Gly) (2), cyclo( L-Pro-L-Ala) (3), cyclo( D-Pro-L-Leu) (4), N-β-acetyltryptamine (5), 2-hydroxybenzoic acid (6), and phenylacetic acid (7). Compound 1 exhibited weak cytotoxic activity against RAW264. 7 cells with IC50 value of 9.1 μmol x L(-1).

BACKGROUND:Chinese medicineTangbikang can improve nerve conduction velocity in diabetic rats, and has anti-inflammatory and antioxidant effects. Insulin like growth factor-I is a key target in the treatment of diabetic peripheral neuropathy. OBJECTIVE:To observe the effect ofTangbikangon the expression of insulin-like growth factor-I and its receptor protein and mRNA in the sciatic nerve of diabetic rat model. METHODS:The experimental diabetes melitus rat models were induced by feeding high fat forage and injection with streptozotocin. After model establishment, rats were givenTangbikang 4.18, 8.35, 16.7 mg/kg per day. This study set positive control methycobal, model and normal control groups. Intragastric administration was performed for 16 weeks. RESULTS AND CONCLUSION: Compared with the model group, blood glucose levels were similar in the methycobal group, but decreased in the high-doseTangbikang group (P < 0.01). Immunohistochemical staining and real-time fluorescence quantitative PCR detection revealed that body mass, motor nerve conduction velocity, insulin like growth factor-I and its receptor protein and mRNA expressions were increased in the methycobal and high-dose Tangbikang groups (P< 0.05 orP < 0.01). Results indicated that Tangbikang can prevent and treat diabetic peripheral neuropathy by promoting insulin like growth factor-I and its receptor.

Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic　segments,the majority of peak systolic longitudinal strain was significantly reduced ( P＜0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3％ and 88.2％(P＜0.01), specificity 100％ and 100％(P＞0.05), and accuracy 60.7％ and 92.8％ (P＜0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9％, its sensitivity and specificity in predicting myocardial ischemia were 83.3％ and 91.7％,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.
