BACKGROUND:Mesenchymal stem cells from human skeletal muscle exhibit multi-directional differentiation potential under the influence of osteogenic proteins such as bone morphogenetic protein 4 (BMP4). But the differentiation of a specific cell subpopulation is not yet clear.OBJECTIVE:To characterize the multi-directional differentiation potential of mesenchymal stem cells from human skeletal muscle based on the expression of different surface markers.METHODS:Four different subpopulations were isolated from the human skeletal muscle by fluorescence-activated cell sorting based on their expression of the myogenic-specific marker CD56 and the endothelial-specific markers CD34 and CD144, including CD56+, CD56+CD34+CD144+, CD34+CD144+, and unsorted groups. Osteogenic differentiation of the four groups of the cells was displayed by Von Kossa staining after the treatment with BMP4 alone or BMP4 plus transforming growth factor β3. Chondrogenic differentiation of these cells was displayed by Alcian blue staining. Bone metabolism was assessed by alkaline phosphatase staining.RESULTS AND CONCLUSION:No significant difference in the bone metabolism was found among four groups after the treatment with BMP4 (P > 0.05). Osteogenic and chondrogenic potentials of the four cell subpopulations were significantly different. Under the same osteogenic induction, the CD56+ cells exhibited strongest potential for osteogenic differentiation; and under the same chondrogenic induction, the CD56+CD34+CD144+ cells exhibited better potential for chondrogenic differentiation than the CD56+ cells. These findings indicate that the osteogenic and chondrogenic potentials are intimately associated with the type of mesenchymal stem cells from human skeletal muscle:the CD56+ cells are closely related to the osteogenic potential, while the CD56+CD34+CD144+ cells have stronger chondrogenic potential.

Objective: To evaluate the applications and problems of statistical methods for articles published in《Chinese Circulation Journal》. Methods: We reviewed the statistical methods for original articles published in《Chinese Circulation Journal》in 2010, 2011 and 2015; general status with problems was analyzed and the situations were compared among different years. Results: A total of 404 articles were enrolled, statistical hypothesis testing was performed in 366 of them, 32 had descriptive statistics only and 6 articles were meta-analysis. The most frequently used statistical methods were student'st-test (57.4%), followed by chi-squared analysis (56.7%), analysis of variance (35.2%) and regression analysis (23.0%). The main statistical problems in Methods included in described method un-matched to really used method and insufifcient or wrong description. The proportion of insufifcient or wrong description in 2010 and 2011 was 36.6% (71/194), while in 2015 was 26.2% (55/210),P=0.02. The major wrong application of statistical approach was ignoring design with improper method and using unsatisifed precondition for speciifc analysis. The proportion of improper statistical method application in 2010 and 2011 was 19.1% (33/173), in 2015 was 19.7% (38/193),P=0.88. Conclusion: The quality of statistics was improved in 2015 than 2010 and 2011 for articles published in《Chinese Circulation Journal》; while there were still problems at certain degree, enhanced statistical review should be conducted in medical journals.

BACKGROUND:The ankle joint is capable of flexion and extension, including plantar flexion and dorsiflexion, to act as a support and a lever. An ankle injury, often accompanied by fracture and ligament injury, seriously threatens the ankle joint function. Previous diagnosis of ankle injury mainly relied on clinical signs and X-ray examination. However, X-ray examination is not accurate enough for ankle injury diagnosis because it cannot clearly diagnose damage to the surrounding ligaments, tendons and other soft tissues except for obvious fractures. Mutlisequence and multiplanar MRI is currently the optimal noninvasive method for high-resolution determination of soft tissue deformations, but little has been reported on the diagnostic accuracy of ankle ligament and tendon injury. OBJECTIVE:To observe the diagnostic value of MRI for ligament and tendon injury of the ankle in its normal position, and during complete plantar flexion and dorsiflexion. METHODS:It is a single-center, prospective, diagnostic trial that wil be completed at the First Hospital of Hebei Medical University, China. Sixty cases were recruited, including 30 cases of normal ankle joint and 30 cases of ankle ligament and tendon injury. MRI scans of the ankle joint in normal position, complete plantar flexion and complete dorsiflexion were performed in al the cases, and the multi-position MRI results were compared. The primary outcome measure is the sensitivity of MRI to ligament and tendon injury of the ankle during complete plantar flexion. The secondary outcomes include the specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of MRI to ligament and tendon injury of the ankle during the complete plantar position as wel as rate of correct diagnosis;specificity and sensitivity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio in normal position or during the complete dorsiflexion as wel as rate of correct diagnosis;the morphology of the ankle on the multi-position MRI. This study design was registered at ClinicalTrial.gov (03049423) on February 8, 2017. This study protocol has been approved by the Medical Ethics Committee of Qinghai University Affiliated Hospital of China (approval No. 2015076) and wil be performed in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. Signed informed consent regarding trial procedure and treatment was obtained from each volunteer. DISCUSSION:This study aims to determine the rate of correct diagnosis of ankle ligament and tendon injury using the MRI, to clarify the diagnostic value of MRI for ankle ligament and tendon injury, and to provide a quantitative MRI diagnostic standard for developing a reasonable surgical treatment.

Objective To investigate the effect of fluvastatin (FLV) on the expression of β1 integrin in puromycin aminonucleoside (PAN)-treated podocytes and its mechanism.Methods Cultured human podocytes were divided into PAN,different concentrations of fluvastatin (1 × 10-8 to 1 × 10-5 mol/L),SOD,H2O21 groups respectively.Expressions of β1 integrin and reactive oxygen species (ROS) in podocytes were detected by Western blotting and DCFHDA (2' 7'-Dichlorofluoresecein 3' 6'-diacetate) respectively.The viability of podocyte was determined by MTT colorimetry.Results PAN and H2O2 significantly decreased the expression of β1 integrin and increased the synthesis of ROS in podocytes (P＜0.05respectively).Lower concentration fluvastatin or SOD treatment up-regulated β1 integrin and downregulated ROS of podocytes induced by PAN (P＜0.05 respectively).MTT revealed that lower podocyte viability was found in higher concentration fluvastatin,PAN and H2O2 groups.Lower concentration fluvastatin and SOD could protect podocytes against PAN.Conclusion Fluvastatin attenuates the injury of podocyte induced by PAN and increases the expression of β1 integrin,whose mechanism may be associated with the inhibition of the ROS activity.

Objective To explore the effect and mechanism of fluvastatin on the expression of fibronectin(FN) in human peritoneal mesothelial cells (HPMCs) induced by high-glucose peritoneal dialysate (HGPDS).Methods Cultured HPMCs were randomly divided into control,HGPDS,HGPDS plus GSK650394 10-5 mol/L (the competitive inhibitor of SGK1),different concentrations of fluvastatin,fluvastatin 10-6 mol/L and GSK650394 10-5 mol/L alone.The morphology change of HPMC was observed by light microscopy.The cellular viability was detected by MTT colorimetry.The mRNA and protein expressions of serum and glucocorticoid-inducible kinase 1 (SGK1) and FN were detected by RT-PCR,Western blotting or ELISA.Results After incubation with HGPDS,the cell morphology changed from typical cobblestone-like appearance to fibroblast-like appearance,and the cell viability was inhibited significantly (P＜0.05).Fluvastatin 10-6mol/L and GSK650394 could improved the cell morphology and the cell viability injured by HGPDS (P＜0.05).Compared with the normal control group,the mRNA and protein expressions of SGK1 and FN increased significantly in HPMC treated with HGPDS(P＜0.05).GSK650394 significantly decreased the high expression of SGK1 and FN (P＜0.05),also the fluvastatin had same effects as GSK650394 in dose-dependent manner (P＜0.05).Conclusions High-glucose peritoneal dialysate can increase FN expression in human peritoneal mesothelial cells,which can be attenuated by fluvastatin.The protective role of fluvastatin in HPMC may be partially achieved through the signal pathway of SGK1.

Objective: To evaluate the potential effect of zinc, copper, and selenium on placental cadmium transport. Methods: Pregnant women were selected from Daye,Hubei Province. Whole blood, cord blood and placenta were collected, and Cd levels were determined by inductively coupled plasma emission mass spectroscopy. Zn, Cu, and Se levels in whole blood were also determined. The potential association between essential elements and placental Cd transport was evaluated. Results: Whole blood Cd (0.8–25.2?g/L) in 47 pregnant women aged 20 to 34 years was significantly higher than that in cord blood(0.020–1.48?g/L). Placental Cd ranged from 0.082 to 3.97 ?g/g dry weight. Multiple linear regression indicated that lower maternal blood Cu was significantly associated with higher cord blood Cd. Placental Cd in pregnant women with lower maternal Zn was significantly higher than that in those with normal Zn level. Placental Cd in pregnant women with lower maternal Se was significantly lower than that in those with normal Se level. Conclusion: Essential elements, such as Cu, Se, and Zn might affect placental Cd transport.
