We compared the total errors observed from both precision and accuracy validation experiments with defined medically allowable errors for each quantitative test,and used Westgard's method evaluation decision chart for initial judgement of the acceptability of method validation performance. Moreover,we need to judge the acceptability of other method validation parameters,so that we could integratedly assess and judge whether the testing system is acceptable to use in the laboratory.

Objective · To clarify effect of adipose stem cells derived conditioned medium (ASCs-CM) on fibrogenesis of dermal fibroblasts costimulated by transforming growthfactor-β1 (TGF-β1), and explore the possible paracrine pathway of ASCs in regulating the dermal tissue rehabilitation.Methods · Co-stimulated by TGF-β1, dermal fibroblasts were treated with different concentrations of ASCs-CM. Variouscellular events including cell proliferation, apoptosis, and mRNA and (or) protein levels of α-smooth muscle actin (α-SMA), type Ⅰ collagen (COL-1) , type Ⅲ collagen (COL-3), hepatocyte growth factor (HGF), basic fibroblast growth factor (FGF-2) were explored. Furthermore, the effect of HGF antibody on apoptosis of fibroblasts caused by ASCs-CM and TGF-β1 were also observed. Results · ASCs-CM inhibited fibroblasts proliferation caused by TGF-β1 and lead to cell apoptosis. α-SMA expression in fibroblasts was attenuated by 10% ASCs-CM +TGF-β1. It was demonstrated that 100% ASCs-CM with TGF-β1 had promoted collagens (especially COL-3) expression in fibroblasts, and increased HGF mRNA level as well. HGF antibody inhibited fibroblasts apoptosis produced by 100% ASCs-CM and TGF-β1. Conclusion · ASCs may have an effect on fibrogenesis of dermal fibroblasts co-stimulated by TGF-β1 through a paracrine way.High concentration of ASCs-CM not only increases collagen production and secretion, but also inhibits fibroblasts proliferation and accelerates apoptosis.

OBJECTIVETo evaluate the clinical effect of a new surgical approaches for repairing the acute Achilles tendon rupture.

METHODSFrom January 2009 to January 2014, 21 patients with Achilles tendon rupture were treated by 2 minimally invasive incisions and remaining skin bridge of achilles tendon end including 16 males and 5 females with an average age of 44.3 years old ranging from 21 to 57 years old. Postoperative complications, the range of movement of affected ankle joint, the circumference calf and ankle on both side, time of reture to work and sports activity were observed and recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate the functional recovery.

RESULTSAll patients were followed up for 6 to 36 months with an average of 13.5 months. No skin necrosis, wound infection, deep vein thrombosis,re-rupture and sensory disturbance with the ankle or foot in the sural nerve distribution were found. At 1 year after operation, there was no significant difference in the range of movement between affected foot (55.4 ± 6.5)° and unaffected foot (56.3 ± 3.7)° (t = 0.872, P = 0.325). There was significant difference in AOFAS between preoperative (65.1 ± 6.9) and postoperative (94.3 ± 5.5) (t = 7.672, P = 0.013). All patients returned to work and study at an average of 10 weeks (ranged from 6 to 15 weeks) and 15 patients returned to normal sports activities at 21 weeks (ranged from 18 to 24 weeks). Calf and ankle circumferences decreased by 0.45 cm (0.3 to 0.8 cm) and increased by 0.4 cm (0.2 to 0.7 cm), respectively in the injured leg as compared with the contralateral leg.

ObjectiveTo explore adrenal insufficiency in the preterm infants who had critical lung diseases and the relationship between adrenal insufifciency and long-term or short-term prognosis.Methods The basal cortisol and ACTH of iffty preterm infants enrolled were tested. The peak cortisol at 30 minutes after low dose ACTH stimulation was tested. The adrenal insufifciency was deifned as the concentration of the basal cortisol less than 15 μg/dl or the increment of cortisol concentration after low dose ACTH stimulation less than 9 μg/dl. The pretern infants with adrenal insufifciency were the AI group and others were the adrenal normality, AN group.Results Thirty-one cases were adrenal insufifciency in 50 preterm infants with critical lung disease. The incidence was 62%. The concentrations of the basal and peak cortisol in AI group were lower than those in AN group (P<0.01). The increment of cortisol concentration after low dose ACTH stimulation had not signiifcant difference between two groups. The concentration of ACTH in AI group was lower than that in AN group (P<0.01). The mean arterial blood pressure in AI group was lower than that in AN group (P<0.01). The blood sugar, potassium and sodium had no signiifcant difference between two groups (P>0.05). There was no signiifcant difference in the mortality and the incidence of BPD between two groups (P>0.05).Conclusions The incidence of adrenal insufifciency was high in the preterm infants with critical lung diseases, which may be due to insufifcient production of endogenous ACTH. When the adrenal insufifciency was happened, the blood pressure is relatively low in preterm infants with critical lung diseases, but it was not related to the mortality and the incidence of BPD.

Objective To observe pathological process of intestinal epithelial cells subjected to ischemia,ischemia/reperfusion injury and inflammation simulated hypoxia/reoxygenation (H/R) and lipopolysaccharide (LPS) challenged human fetal normal colonic cell (FHC) line in vivo,and to observe the changes when the assaulted intestinal epithelial cells were treated with emodin,in order to explore the possible intervention targets of emodin.Methods Normoxia group:the FHC cells were cultured in 95％ air and 5％ CO2 at 37 ℃.Hypoxia (H) group:the cells were cultured with a mixed anaerobic gas of 1％ O2,5％ CO2 and 94％ N2 at 37 ℃ for 1,2,3,4 hours.H + LPS group:the cells were cultured in hypoxic condition as H group with simultaneous challenge of LPS (1 mg/L).H/R group:the cells were cultured in hypoxia for 3 hours followed by reoxygenation for 1,2,3 and 4 hours,respectively.H/R + LPS group:the cells were cultured in H/R as H/R group and LPS (1 mg/L) simultaneously.Emodin intervention group:the cells were cultured in H3 h/R2 h + LPS and emodin (20,40,60,80 μmol/L) simultaneously.The variation trends of phosphorylation nuclear factor-κB profilin-o (pIκB-α),phosphorylation NF-κBp65 (pNF-κBp65) and their downstream target gene cyclooxygenase-2 (COX-2),and hypoxia-inducible factor-1α (HIF-1 α) were determined by Western Blot.The morphological changes in intestinal epithelium in different groups were observed using light microscope.The effect of emodin on the proliferation of intestinal epithelial cell was measured by methyl thiazolyl tetrazolium (MTT) assay.Results ① H group:the expressions of pIκB-α,pNF-κBp65 and COX-2 were upregulated,peaking at H1 h (0.350 ± 0.018,1.083 ± 0.054,0.903 ± 0.045),and then they gradually lowered (F value was 3.011,7.247,5.754,P value was 0.013,0.000,0.005,respectively).The expression of HIF-1 α peaked at H3 h (1.511 ± 0.076),but there was no significant difference among different groups (F=1.881,P=0.062).H + LPS group:the expressions of pIκB-α,pNF-κBp65,COX-2,HIF-1α were increased with elongation of duration of hypoxia,and a maximal induction was observed at H3 h (0.504 ± 0.025,1.255 ± 0.063,0.812 ± 0.041,1.209 ± 0.075,F value was 2.683,8.774,9.765,2.432,and P value was 0.011,0.000,0.000,0.026,respectively).H/R group:with the prolonged duration of reoxygenation,the expressions of NF-κB signaling pathway proteins (pIκB-α,pNF-κBp65,COX-2) were decreased and dropped to nadir at H3 h/R4 h (0.712 ± 0.034,1.202 ± 0.048,0.691 ± 0.042,F value was 1.923,6.765,2.719,and P value was 0.063,0.000,0.016,respectively).Compared with H group,HIF-1α was decreased with a prolonged duration of reoxygenation in H/R group,but there was no significant difference in value among different time points (F=1.280,P=0.081).H/R + LPS group:pIκB-o,pNF-κBp65,COX-2,HIF-1α showed no sign of degradation with the prolonged duration of reoxygenation,and their expression increased to maximum analogously at R2-3 h (3.302 ± 0.061,2.315 ± 0.055,2.017 ± 0.043,2.413 ± 0.098,Fvalue was 4.614,1.652,5.970,2.076,and Pvalue was 0.001,0.067,0.000,0.037,respectively).Emodin group:emodin when co-treated with H/R + LPS inhibited the expression of HIF-1o and NF-κB pathways with a dose-effect relationship (P＜0.05 or P＜0.01).Emodin at the dose of 80 μmol/L showed most marked inhibition (2.599 ± 0.130,1.772 ± 0.089,2.590 ± 0.129,2.518 ± 0.125).However,after treatment of emodin did not show such effect.② After treatment with H/R + LPS,there were morphological changes in cells:vacuoles,deformation and fusion.The speed of cell growth became much slower compared with H group.③ Emodin (20-80 μmol/L) had no significant effect on cell proliferation.Although emodin produced biological effect in this concentration range,it had no cellular toxicity.Conclusions Both hypoxia and inflammation can activate the hypoxia pathway of HIF-1α and the pro-inflammatory pathway of NF-κB,but different stimuli cause varying degrees of activation in these two pathways.In H/R group,both pathways were weakened during reoxygenation.However,in H/R + LPS group,the proteins remained to show a relatively high expression during the process of reoxygenation.This may be related to the pathophysiological mechanism of intestinal ischemia/reperfusion injury:hypoxia/reperfusion injury and LPS act together to destroy the intestinal epithelial cells and induce gut-derived sepsis.Emodin may inhibit inflammation by blocking HIF-1α/NF-κB-COX-2 signaling pathways.
