Objective To supply large amount of seed cells for the cartilaginous tissue engineering,adult adipose-derived stem cells(ADSCs) were differentiated directly into cartilaginous cells.Methods Adipose tissue donated voluntarily by the adult patients after liposuction was isolated and subcultured.The cell activity was detected by methyl thiazolyl tetrazolium(MTT) assay and the proliferation curve line was drawn.The cultured stem cells were identified with flow cytometry.After the subculturing,the fourth generation of ADSCs were differentiated directly into cartilaginous cells,and then were marked by Alcian blue.Type II collagen expression in the ADSCs after cartilaginous differentiation was examined by immunohistochemical assay.Results ADSCs proliferated in vitro fast,and kept a stable multiplication till the 13th~15th generation.The results of flow cytometry showed that the cultured ADSCs had the specific features of the stem cells,and then were differentiated into cartilaginous cells.Positive Alcian blue staining and type II collagen expression indicated that the obtained cells had the function of normal cartilaginous cells.Conclusion ADSCs are differentiated directly into cartilaginous cells successfully,which will supply seed cells for the cartilaginous tissue engineering.

Objective · To observe the vascular structure before autogenous arteriovenous fistula (AVF) construction in patients with end-stage renal disease (ESRD) and analyze the risk factors of the pre-existing venous neointimal hyperplasia. Methods · The 8 vein samples were screened from 20 ESRD patients at their first time of the AVF construction (non-stenosis group), and the other 8 vein samples were screened from 15 ESRD patients at their at least second time of the AVF repair operation (stenosis group). Sections were prepared and stained with hematoxylin & eosin (H-E) or Masson's trichrome for observation. The intimal thickness was measured by the cellSens software, and its correlation with patients' renal function, calcium-phosphorus metabolism, iron metabolism and inflammatory reaction in the non-stenosis group were analyzed. Results · In the non-stenosis group, there were varying degrees of intimal hyperplasia in 5 (62.5%) cases, loss of endothelial cell layer in 3 (37.5%) cases, and vascular wall replacement by collagenous with atrophy or loss of muscle layer in 5 (62.5%) cases. In the stenosis group, almost all vein samples showed general thickening of the wall and 2 (25.0%) totally lost the muscle layer. Avg It of those two groups were statistically significant (P<0.01). In the non-stenosis group, both of average I/M thickness and average I/M area were negatively related to glomerular filtration rate (GFR) (P<0.05) and positively related to serum phosphorus and calcium-phosphorus product (P<0.05). Conclusion · Some apparently normal vein of ESRD patients showed varying degrees of intimal hyperplasia before AVF construction. The intimal hyperplasia had a remarkable correlation with GFR or calcium-phosphorus metabolism. Early intervention of the intimal hyperplasia prior to AVF construction may be a new prevention and control means.

The purpose of this study was to evaluate the effect and safety of Jinlong capsule combined with chemotherapy or radio-therapy for non-small cell lung cancer (NSCLS) using Meta-analysis. PubMed, Embase, CNKI and Wanfang databases were all searched without language restriction, and searching time was from January 1990 to July 2015. All eligible published studies were included in this study for quality assessment and data extraction. All the data were analyzed using Revman 5.3. A total of ten studies including 736 subjects (370 in Jinlong capsule plus chemoradiotherapy and 366 in chemoradiotherapy only) were finally included in this Meta-analysis. The result of Meta analysis showed that compared with pure chemoradiotherapy group, Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the patients' curative effect (OR = 1.77, 95% CI: 1.29-2.43, P < 0.05), clinical benefit rate (OR = 1.89, 95% CI: 1.22-2.91, P < 0.05), life quality improvement rate (OR = 2. 56, 95% CI: 1.61-4.05, P < 0.05), and decrease leucopenia incidence rate (OR = 0.35, 95% CI: 0. 22-0.56, P < 0.05) and gastrointestinal reaction rate (OR = 0.67, 95% CI: 0.40-1.11, P < 0.05). The pooled results showed that Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the curative effect and life quality, and decrease the adverse reaction of patients.

Objective For developing safe and effective anti-radiation new drugs,the effects of different lipoic acid amino acid salts on radiosensitivity were investigated.Methods The free radical scavenging ability of the above salts was evaluated in Fenton system.CCK-8 assay and flow cytometry assay were performed to evaluate the survival rate of L02 and apoptosis of AHH-1 after γ-ray irradiation,respectively.Results The lipoic acid arginine salt had the best ability of scavenging free radicals in Fenton system with an IC50 of 8.40 μ moL/ml.The survival assay showed that lipoic acid amino acid salts had better stability and equal ability in radioprotection (P ＞ 0.05) compared with lipoic acid.The apoptosis assay indicated that all lipoic acid amino acid salts could inhibit radiation-induced apoptosis,where lipoic acid arginine salt was more effective (t =-6.67,P ＜ 0.01).Conclusions Lipoic acid arginine salt has good radioprotection effect on L02 and AHH-1 cells by scavenging free radicals.

Objective To investigate the dose-effect relationship of mRNA level of sensitive mitochondrial genes in human lymphoblastoid cells induced by ionizing radiation.Methods Seven human sensitive genes,including ND3,Cyt b,COX Ⅰ,COX Ⅱ,COX Ⅲ,ATPase6 and ATPase8 were chosen.Changes of mRNA level of these genes were detected by RT-PCR and Real-Time PCR at 24 h after irradiation in human lymphoblastoid cells,which were exposed to 0 - 15 Gy of 60 Co γ-rays.Results The expression of these 7 genes at mRNA level was up-regulated 24 h after irradiation in human lymphoblastoid cells.The level of gene expression of COX Ⅰ,which belongs to complex Ⅳ of mitochondrial respiratory chain,was most obvious,and the peak occurred after irradiation of 8 Gy,which was 13 times of the control group.A good dose-effect relationship was showed for COX Ⅲ gene expression at dose range of 3 -10 Gy as well as 3 - 15 Gy for other 3 genes including ND3,ATPase6 and ATPase8.Conclusions Gene expression levels of COX Ⅲ,ND3,ATPase6 and ATPase8 24h post-irradiation at certain irradiation dose range could be used for radiation damage biomarkers.

Objective To explore the changes of human mitochondrial COX Ⅰ , COX Ⅱ and COX Ⅲ genes expression induced by ionizing irradiation. Methods Changes of human COX genes expression were detected by RT-PCR and Real-time PCR 8 h after the irradiation in human lymphoblastoid cell lines,which were exposed to 1-10 Gy60Co γ-rays. The protein levels were detected by flow cytometry and the COX activity was measured by colorimetry. The dose-effect relationships between the expression changes of the genes and the doses were established. The changes of these genes expression were also analyzed at different post-radiation time-points between 0. 5 h and 72 h after irradiation of 5 Gy in order to explore the time-effect. Results The expression of 3 genes at mRNA level was up-regulated. A good dose-effect relationship was showed for COXⅠ and COX Ⅲ at dose range of 0-3 Gy and 0-8 Gy for COX Ⅱ ( F COXⅠ=116. 62, FCOXⅡ = 17. 89, FCOXⅢ = 8.20, P ＜ 0. 05). For the time-effect after irradiation, the gene expression levels of COX Ⅱ and COX Ⅲ genes were up-regulated and the peak change occurred at 4 h after irradiation. For COX Ⅰ gene, the mRNA expression levels were down-regulated during 0.5-72 h( FCOXⅠ =31.99, FCOXⅡ = 19.47, FCOXⅢ = 20. 64, P ＜0. 05 ). At the protein level, the levels of COX Ⅰ and COX Ⅱ were lowered in lower doses and enhanced in higher doses, and the levels of COX Ⅲ were decreased at all dose levels (FCOX Ⅰ = 16.96, FCOXⅡ = 32.5, FCOXⅢ = 6. 51, P ＜ 0. 05 ). The protein levels of COX Ⅰ and COX Ⅱ were enhanced during 4-72 h and 8-72 h respectively after 5 Gy irradiation ( FCOX Ⅰ = 14.68,FCOXⅡ = 17. 18, FCOXⅢ =2. 52, P ＜0. 05). The activities of COX were lowered at different dose levels and different time-points. Conclusions Ionizing radiation might induce the changes in mitochondrial COX Ⅰ,COX Ⅱ and COX Ⅲ gene expression, and lead to the reduction of the COX activities.

Objective: To explore independent risk factors of coronary artery calcification (CAC) and analyze correlation among risk factors of CAC and serum osteopontin (OPN) level. Methods: According to results of 64-slice spiral computed tomography (MSCT) coronary angiography, a total of 65 patients were continuously enrolled and divided into CAC group (n=37) and non-CAC control group (n=28). Enzyme linked immunosorbent assay (ELISA) was used to measure serum level of OPN. Single factor and multiple factor Logistic regression analysis’s were used to analyze risk factors of CAC. Spearman’s straight line analysis was used to analyze correlation between risk factors of CAC and serum OPN. Results: 1、 The age, hypertension, diabetes, poor eating habits，lack of exercise, overweight, etc., which were independent risk factors of CAC （OR=3.47～12.96, P=0.018～0.003）by single factor Logistic regression analysis, were inducted to multiple factor Logistic regression analysis, its result showed that age, overweight, poor sleep quality, poor eating habits were independent risk factors of CAC, OR=35.31～5.17, P＜0.01～0.05; 2、Serum level of OPN in CAC group was significant higher than that of non-CAC control group ［(39.919±11.879) μg /L vs. (24.000±6.000) μg /L，P<0.01］; 3、The Spearman straight line correlation analysis indicated that serum level of OPN was correlated with risk factors of CAC : positively correlated with LDL-C, overweight, age, TC（r=0.487～0.286,P＜0.001～＜0.05）, and positively correlated with poor sleep quality, diabetes, poor eating habits, lack of exercise（r=4.10～2.24， P<0.01～0.05）; negatively correlated with HDL-C（r=-0.250,P＜0.05）. Conclusion: Correlation analysis indicates that age, overweight, poor sleep quality, poor eating habits etc. are independent risk factors of CAC；Serum OPN level is correlated with LDL-C, overweight，age, diabetes, lack of exercise etc., so these indicate that must decrease OPN level and risk factors of CAC to relieve CAC and slow down its development.

Objective To evaluate the effect of splenectomy on development and progression of implanted hepatic tumors by establishing implanted hepatic tumor rat model with portal hypertension. Methods Rat cirrhosis with portal hypertension models were built by subcutaneous injection of carbon tetrachloride, and then the rats were randomly divided into two groups. Group A was subjected to splenectomy and implantation of Walker-256 tumor tissue on the left lobe of liver, and group B was only subjected to implantation of tumor tissue. T-lymphocyte subsets CD4, CD8 and CD4/CD8 of two groups were examined 10 days after implantation of tumor tissue; the left lobe of liver was resected and the maximal tumor size was measured; expression of Ki-67 was detected by immunohistochemical method in the tumor tissues. Results The results of blood routine test and liver function test were obviously abnormal in rat model of portal hypertension. The levels of CD4 and CD4/CD8 in group A were higher than those in group B (0.36±0.01 vs 0.35±0.02,1.33±0.08 vs 1.24±0.05; P<0.05 or P<0.01), and the level of CD8 in group A was lower than that of CD8 in group B (0.27±0.01 vs 0.29±0.02, P<0.01). There was no significant difference in the diameter of hepatic tumor between the two groups. Ki-67-positive rate of tumor in group A was lower than that in group B (P<0.05). Conclusion Splenectomy in portal hypertension rats can not only help to improve the immunity against hepatic tumor, but also decrease the invasive ability of the hepatic tumor to some extent.

Objective To investigate the neuroprotective effect and possible mechanism of Compound Porcine Cerebroside and Ganglio-side Injection (CPCGI) on cerebral ischemia-reperfusion injury in rats. Methods Healthy adult male Sprague-Dawley rats were divided into sham group (n=10), model group (n=10), CPCGI low dosage group (n=10) and high dosage group (n=10), and control group (Ginkgo biloba extract, n=10). All the rats was subjected to middle cerebral artery occlusion (MCAO) for two hours and reperfusion except sham group, and received treatment for fourteen days once reperfusion started. They were tested with modified Neurological Severity Score one, three, seven and fourteen days after MCAO, and adhesive-removal test and beam-walking test fourteen days after MCAO. The expression of Beclin1, PINK1 and Parkin were detected with Western blotting. Results Compared with the model group, the Neurological Severity Score reduced (P<0.05) and the time crossing the beam reduced (P<0.01) in all the medical groups fourteen days after MCAO, and the time removing the adhesive paper reduced in the CPCGI groups (P<0.01). The expression of Beclin1 and Parkin decreased and the PINK1 level increased in the model group (P<0.01), and it was reversed in all the CPCGI groups (P<0.05). Conclusion CPCGI could relieve the cerebral ischemia-re-perfusion injury in rats through the regulation in mitophagy.
