Randomized Controlled TrialComparison of HbA1c in Chinese patients with type 1 or type 2 diabetes randomized to twice daily insulin lispro low mix 25 or twice daily human insulin mix 30/70.
Glycemic control prevents onset and progression of diabetes-related long-term complications. The objective of this study was to demonstrate that twice daily insulin lispro low mix 25 is noninferior to twice daily human insulin mix 30/70 in achieving glycemic control as measured by hemoglobin A1c (HbA1c), from baseline to endpoint, in patients with type 1 or 2 diabetes. ⋯ The results support noninferiority of twice daily insulin lispro low mix 25 versus twice daily human insulin mix 30/70 in HbA1c control in Chinese patients with type 1 or 2 diabetes.

Clinical TrialEfficacy and safety of placing nasoenteral feeding tube with transnasal ultrathin endoscope in critically ill patients.
The placement of an enteral feeding tube is the foundation for providing enteral nutrition. But due to the anatomic complexity of the stomach and the duodenum, to a certain degree, there are some technical difficulties in the placement of postpyloric feeding tube, especially in critically ill patients. This study aimed to evaluate the efficacy and safety of placing nasoenteral feeding tube with a transnasal ultrathin endoscope. ⋯ The method of placing nasoenteral feeding tube with the transnasal ultrathin endoscope is not only efficient, time-saving, technically simple, and painless to patients, but also safe especially in critically ill patients.

Relationship of plasma creatinine and lactic acid in type 2 diabetic patients without renal dysfunction.
As one of most widely-used biguanides, metformin can induce the lactic acidosis in patients with renal failure though its incidence is very low. However, lactic acidemia induced by metformin was reported in patients without renal dysfunction. It is unclear that whether lactatemia exists in diabetic patients with normal renal function in Chinese or not and its influencing factors. This study aimed to clarify the influencing factors of lactic acid, and identify a practiced clinical marker to predict the hyperlactacidemia in diabetics with normal renal function. ⋯ Metformin can increase the incidence of lactatemia in type 2 diabetic patients without renal dysfunction. Cr, ALT, and BMI are independent associated factors of blood lactic acid levels. There is low proportion of lactatemia in type 2 diabetics without metformin therapy, the optimal cutoff of Cr to predict lactatemia in these patients is 96.5 micromol/L.

MRI findings in injured articular cartilage of the knee correlated with surgical findings.
There is a strong need for quick noninvasive diagnostic technique that can give a valid estimate of the status of the cartilage reliably, discriminating intact cartilage from various grades of impaired cartilage. The goal of this study was to assess the incidence of knee cartilage injuries and compare the accuracy of two-dimension spin echo (2D SE) and fast spin echo (FSE) (conventional MRI), three-dimensional spoiled gradient echo (3D SPGR), three-dimensional fast imaging employing steady state acquisition (3D FIESTA) MR imaging sequences with surgical examination of the articular cartilage. ⋯ For all the articular surfaces of the traumatic knees, about one fifth (22%) were cartilage defects. Both 3D SPGR and 3D FIESTA imaging performed similarly in detecting cartilage lesions of the knee. The increased accuracy in chondral assessment can be achieved by combining 3D SPGR and conventional MRI within a reasonable time.

Identification of differentially expressed microRNAs by microarray: a possible role for microRNAs gene in medulloblastomas.
MicroRNAs (miRNAs) are small noncoding regulatory RNAs whose aberrant expression may be observed in many malignancies. However, few data are yet available on human primary medulloblastomas. This work aimed to identify that whether miRNAs would be aberrantly expressed in tumor tissues compared with non-tumorous cerebellum tissues from same patients, and to explore a possible role during carcinogenesis. ⋯ MiRNAs are differentially expressed between human medulloblastoma and non-tumorous cerebellum tissue. MiRNAs may play a role in the tumorigenesis of medulloblastoma and maybe serve as potential targets for novel therapeutic strategies in future.
