Tendons are dense connective tissues that mediate the attachment of the muscle system to the skeletal system. While the methods for clinical tendon repair remain less satisfactory, tissue engineering may pro- vide promising future. Therefore, understanding the natural tendon development process is important for tendon en- gineering. Scleraxis and Tenomodulin are relatively specific molecule makers for tendon and ligment and play im- portant roles in the tendon development. This article gives review of the molecular structure, the expression regula- tion, and the roles of Scleraxis and Tenomodulin in tendon development, in order to better understand the process of tendon development.

Serum adipocyte fatty acid-binding protein (A-FABP) was raised in metabolic syndrome (MS)patients (n= 121) as compared with age-matched healthy subjects [n = 120, (14.7±4.8 vs 6.8 ±3. 0) μg/L,P<0.001]. It reached higher level in MS subjects with visceral obesity [(15.7±4.2 vs 12.6±5.1) μg/L, P<0.001]. Serum A-FABP concentration was positively correlated with body mass index, waist circumference, waist-tohip ratio, fasting insulin, homeostasis assessment for insulin resistance (HOMA-IR), fasting glucose, triglycerides,total cholesterol,and mean arterial blood pressure, whereas negatively correlated with HDL-C (r =-0. 448, P< 0.001).

A total of 121 patients with metabolic syndrome (MS) and 120 normal subjects were recruited for exploring the association of serum adipokines with MS. The levels of resistin and adipocyte fatty acid-binding protein (A-FABP) increased, while adiponectin decreased gradually ( all P<0.05 ) in normal control group, MS without abdominal obesity group, and MS with abdominal obesity group. In MS group, resistin was positively correlated with body mass index ( BMI), waist circumference, systolic blood pressure, fasting plasma glucose, and A-FABP ( P<0.05 or P<0.01 ). Adiponectin was positively correlated with high-density lipoprotein-cholesterol and negatively correlated with BMI, waist circumference, fasting insulin, triglyceride, and homeostasis assessment of insulin resistant index.

BACKGROUND:It has been shown thatChuanglingye has good anti-inflammatory effects, inhibits platelet aggregation and thrombus and improve wound healing. OBJECTIVE:To investigate the effects ofChuanglingye-loaded colagen on regulating inflammation and healing process of chronic wounds. METHODS: Forty rats were selected to make chronic wound models and randomly divided into four groups at 3 days after modeling: control group, colagen group,Chuanglingye group,Chuanglingye-loading colagen group, 10 rats in each group, respectively treated with 0.2 mL normal saline, 0.2 mL Chuanglingye, colagen and Chuanglingye-loaded colagen. The size of wounds was measured when modeling and at 3, 7 and 15 days after modeling. Amount of white blood cels, interleukin-6 level and tumor necrosis factor-α level in wound exudates were detected. The levels of hydroxyproline and matrix mentaloproteases (MMPs), including MMP-1, MMP-2, MMP-9, in the granulation tissue, were also detected. RESULTS AND CONCLUSION:At 3, 7, 15 days after modeling, the amount of white blood cels and levels of interleukin-6, tumor necrosis factor-α, MMP-1, MMP-2, MMP-9 were significantly lower in the Chuanglingye-loaded colagen group andChuanglingye group compared to the control group and colagen group (P < 0.01, P < 0.05). But there was no significant difference betweenChuanglingye-loaded colagen group and
Chuanglingye group. The level of hydroxyproline in the granulation tissue was significantly higher in the Chuanglingye-loaded colagen group than the other three groups at 3, 7, 15 days after modeling (P < 0.05), and the size of wound in theChuanglingye-loaded colagen group was significantly lower than that in the other three groups at 15 days after modeling (P < 0.01). In addition, no significant difference was found among the four groups at 15 days after modeling. These findings indicate thatChuanglingye-loaded colagen can significantly depress proliferation and infiltration of inflammatory cels on the wound surface, decrease levels of inflammatory factors and MMPs in wound exudates, and thus promote the healing of chronic wounds.

Objective To discuss the anticancer role of arsenic trioxide (ATO) with cisplatin on human oral carcinoma HSQ-89 cells. Methods The human oral epidermoid HSQ-89 cells were chosen as the subjects. Different concentrations of ATO were added into Cisplatin(DDP)-treated cells. The inhibition rate of tumor cells was detected by MTT assay. Results Different concentrations of ATO (0,2.5,5,7.5,10,12.5 μmol/mL) were added into oral cancer HSQ-89 cells which have been treated with DDP (15 μg/mL). The inhibition rate of tumor cells were 26.9%, 67.5%, 73.0%, 88.5%, 90.4%, 98.7%respectively; The combined application of ATO with cisplatin could improve the inhibition rate of HSQ-89 cells in a dose-dependent relation. Conclusion The combined application of ATO and DDP can produce a synergistic action of inhibition on oral cancer cell.

Objective To explore the clinical prognostic significance of arterial blood lactate level and early lactate clearance rate in elderly septic patients. Methods Totally 82 elderly septic patients who were admitted into emergency department were enrolled.Their arterial blood lactate levels were tested at admission and 6 hours later. Early lactate clearance rate was calculated as following:(lactate level of admission minus lactate level of 6 hours later) /lactate level of admission ×100 ％. Heart rate and blood pressure were recorded at admission,and the acute physiology and chronic health evaluationⅡ (APACHE Ⅱ ) score was evaluated in the first 24 hours.28 days after admission was the end of research.Patients were divided into survival group (n=59) and death group (n=23).Taking 10％ as cut-off,patients were divided into high lactate clearance (≥ 10％) group (n=59) and low lactate clearance (＜10％) group (n=23).Values of arterial blood lactate level,APACHE Ⅱ score and early lactate clearance to predict the prognosis of elderly septic patients were determined by ROC curves. Results Arterial blood lactate level was lower in survival group than death group[(2.4± 1.7)mmol/L vs.(3.9±3.2)mmol/L,P＜0.01].Early lactate clearance was higher in survival group than death group [(339.0 ± 28.0) ％ and (300.0 ± 81.0) ％,P ＜ 0.01].Mortality of high lactate clearance group was decreased as compared with low lactate clearance group [18.6％ (11/59) and 52.2％ (12/23),P＜0.01].The thresholds of early lactate clearance to predict mortality of elderly septic patients were 24.0％ (sensitivity 72.9％,specificity 65.2％) which was more valuable than APACHE Ⅱ score ( sensitivity 65.2 ％,specificity 57.6 ％). Conclusions Arterial blood lactate level and early lactate clearance were meaningful predictors for prognosis of elderly septic patients.

Objective:To report a Chinese family with a novel ABCD1 gene mutation at c.332T>G (p.V111G) site and discuss its clinical characteristics and molecular mechanism.Methods:The clinical data, laboratory examination, and imaging examination results were analyzed to make the clinical diagnosis of a middle-aged onset patient from the First Affiliated Hospital of Zhengzhou University in May 2017. High-throughput sequencing was used to discover a novel ABCD1 gene mutation. Sanger sequencing was used to find out whether other family members contain the same ABCD1 gene mutation. The pathogenicity of this mutation was explored by protein structure prediction and pathogenicity analysis. Adrenoleukodystrophy protein-green fluorescent protein (ALDP-GFP) and ALDP-GFP (V111G) plasmids were constructed and human embryonic kidney 293 cells were transfected, then immunofluorescence and Western blotting were used to explore the molecular mechanism of this mutation (completed in Henan Provincial People′s Hospital).Results:The proband (a 39-year-old male) was diagnosed as adrenomyeloneuropathy, a subset of X-linked adrenoleukodystrophy, with a novel heterozygous missense mutation in the ABCD1 gene at c.332T>G (p.V111G) site, and his mother and two daughters were all carriers. Protein structure prediction and pathogenicity results suggested that this mutation is pathogenic. Overexpression of ALDP-GFP (V111G) in the human embryonic kidney 293 cells resulted in a significant decrease in the expression levels of ALDP and the abnormal localization from the peroxisomal membrane to the cytoplasm, accompanied by significant down-regulation of LC3-Ⅱ/LC3-Ⅰ and beclin-1.Conclusion:c.332T>G (p.V111G) is a novel pathogenic mutation in the ABCD1 gene, which causes adrenomyeloneuropathy by impairing autophagy.
