MicroRNAs (miRNAs) are endogenous non-coding RNAs discovered in recent years that post-transcriptionally regulate the gene expression. They are implicated in various biological processes including development,oncogenesis,viral and immunological diseases. Many miRNAs are highly expressed in the cardiovascular system and play an important role in cardiovascular health and diseases. In this paper,we briefly review the recent understanding of miRNAs and their role in cardiovascular pathophysiology.

Objective To analyze the atypical CT and MRI findings of renal cell carcinoma (RCC) and to discuss how to improve the diagnostic accuracy of RCC using CT and MRI. Methods The data of 100 cases of RCC (71 males and 29 females;age range from 29 to 75 years with a mean of 55 years) were reviewed.The surgical and pathological findings showed clear cell carcinoma in 82 cases,mixed cell carcinoma in 8,granular cell carcinoma in 5,papillary RCC in 4 and sarcomatoid RCC in 1.A total of 101 masses were found.The masses were 0.8 to 9.0 cm (mean,4.3 cm) in greatest dimension. According to the CT and MRI findings of most cases in this group and the relevant information in literature,the typical CT and MRI findings of RCC were summarized. The atypical CT and MRI findings of RCC were analyzed,and correlated with surgical and pathological findings. Results There were 17 cases presenting with atypical CT and MRI findings.The atypical CT and MRI findings of RCC were divided into 4 types:① hypovascular RCC (12 cases,including 3 of clear cell carcinoma, 1 of mixed cell carcinoma, 5 of granular cell carcinoma and 3 of papillary RCC);②cystic RCC (3 cases of clear cell carcinoma);③RCC with volumes of hemorrhage (1 case of papillary RCC);④tumor's diameter less than 1㎝ (1 case of clear cell carcinoma). Conclusions Correct evaluation of the CT/MRI findings of hypovascular and cystic RCC,application of adequate scanning methods and careful interpretation of the imaging films are helpful for improving diagnostic accuracy of RCC.

As patients with type 1 diabetes,both the function and number of their beta cells decreased.Despite treating with insulin in early stage,it can't avoid the occurrence of serious complications or death.However,Immunotherapy,different from the previous replacement therapy,emphasizes re-balance between affected T cells and immune regulative effect,suppresses autoimmune reaction,and strengthens the tolerance of beta cells of islet to it.At present,a variety of immune medicines have already been approved for the treatment of type 1 diabetes,such as anti-CD3 monoclonal antibody,GAD-alum,etc.

Objective To observe the effect of lung protective ventilation strategy on oxygenation and pulmonary inflammatory response in dogs with severe smoke inhalation injury.Methods Twelve local healthy male dogs were selected and anesthetized underwent endotracheal intubation, the time controlled smoke was applied to replicate the model of severe smoke inhalation injury, and they were divided into two groups according to the random number table: conventional ventilation group (CV group) and protective ventilation group (PV group), each receiving corresponding ventilation mode for 8 hours respectively. The blood gas analyses were detected before injury, immediately after injury and at ventilation for 2, 4, 6, 8 hours. The contents of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10) in serum were detected by the enzyme-linked immunosorbent assay (ELISA) at each time point. Animals were killed after 8-hour ventilation, and different parts of the lung tissues were obtained for pathological examinations of lung tissues and evaluation of injury scores. The levels of inflammatory factors as TNF-α and IL-10 in lung homogenates were measured by ELISA.Results The arterial partial pressure (PaO2) levels in CV and PV groups were significantly decreased after injury compared with those before injury [mmHg (1 mmHg = 0.133 kPa): 57±19 vs. 128±31, 58±15 vs. 126±22, bothP < 0.01]. Compared with those before injury, the pH values and arterial carbon dioxide partial pressure (PaCO2) levels after injury in two groups had no statistically significant differences at each time point (bothP > 0.05). At 6 hours ventilation, PaO2 level in PV group was significantly higher than that in CV group (mmHg: 121±11 vs. 105±11,P < 0.05). The comparisons of PaO2 levels, pH values and PaCO2 levels at 2, 4, 8 hours of ventilation between the two groups showed no statistically significant differences (allP > 0.05). The histopathological changes revealed that there were alveolar tissue edema and inflammatory cells infiltration in both groups, the degree of severity in CV group was more prominent and its pulmonary tissue injury score was higher than that in PV group (3.68±0.22 vs. 3.27±0.35, P < 0.05). The serum levels of TNF-α and IL-10 after smoke injury were significantly increased in CV and PV groups [TNF-α (μg/L): 4.32±1.13 vs. 0.35±0.11, 4.51±2.02 vs. 0.41±0.08; IL-10 (ng/L): 16.73±2.31 vs. 4.27±0.56, 18.39±3.15 vs. 4.03±1.07, allP < 0.01]. Compared with CV group, the levels of TNF-α were significantly lower at 6 hours and 8 hours of ventilation [6 hours (μg/L): 2.62±0.34 vs. 3.65±1.08, 8 hours (μg/L): 3.02±0.31 vs. 4.21±1.27, bothP < 0.05), while the contents of IL-10 were obviously increased in PV group [6 hours (ng/L): 21.07±2.95 vs. 16.11±3.02, 8 hours (ng/L): 23.57±2.69 vs. 18.28±3.21, bothP < 0.05]. The content of TNF-α in lung homogenate in CV group was significantly higher than that in PV group (μg/L: 5.85±2.57 vs. 3.08±1.17,P < 0.05), but the content of IL-10 in lung homogenate of CV group was markedly lower than that in CP group (ng/L: 19.64±3.16 vs. 24.05±2.09, P < 0.05).Conclusion Lung protective ventilation strategy can effectively improve oxygenation and pulmonary inflammatory response in dogs with severe smoke inhalation injury, thus the lung injury is alleviated and the strategy has protective effect on damaged lung tissues.

Objective To evaluate the feasibility and efficacy of optical coherence tomography (OCT) in interventional diagnosis and treatment of borderline coronary artery disease. Methods Sixteen 40%-70% angiographically stenotic lesions from 15 patients were enrolled in the current study. Intravascular OCT was applied to each lesion after informed consent was obtained to evaluate stenosis percentage, size of lipid core, thickness of fibrous cap, existence of plaque rupture, and presence of thrombosis or calcification. Therapeutic strategies were made according to OCT outcomes as well as clinical symptoms and electrocardiographic changes. Stent coverage, apposition, and tissue prolapse between stent struts were determined in the patients undertaken percutaneous coronary intervention(PCI). Results Qualitative OCT images were obtained in 14 lesions. Ten lesions were greater than 50% stenosis, with large lipid core and fibrous cap thinner than 65 ?m, and plaque ruptures were noted in 2 of the lesions. PCI were performed in these 10 lesions. Two lesions underwent predilatation and significant intima tearings and dissections were detected with OCT. Repeated OCT after stent implantation showed complete coverage in all 10 lesions. Focal incomplete apposition were noted in 2 lesions. Significant tissue prolapse occurred in 3 lesions and segmental incomplete deployment of stent in 2 lesions. The remaining 4 lesions had small lipid cores, thick fibrous caps but with no plaque ruptures, thus PCI was not performed. Conclusion Intracoronary OCT is an effective tool to determine features of coronary lesions. It plays an important role in diagnosis of vulnerable lesions, strategy-making in treating borderline coronary artery disease and evaluation of immediate result of PCI.
