In the process of chondrocytes development and maturation, the chondrocyte displayed great morphological and biochemical change under the control of kinds of growth factors and changeable environments, such as mechanical stress, or cell density changes. This change of characteristic chondrocytes is controlled by specified signaling pathways, and the autocrine and parocrine factors are playing an important role in the promotion of chondrogenesis. At present, the autocrine and parocrine familys are divided into following types, including the transforming growth factor ? family, fibroblast growth factor family, Hedgehog family, and Wingless family. However, the gene expression is not decided by the only one pathway, but the results of the cooperation of various signals. Therefore, the relationship between the pathways is going to be found and confirmed. To identify the effect of the each factor during the proliferation and differentiation of chondrocytes may direct the development of tissue-engineered cartilage.

Replacement therapy is the most effective method for the treatment of end-stage liver disease,and decellularized liver bioscaffold broadens the research field of the replacement therapy.The present liver bioscaffold preparation is to perfuse chemical reagents (detergents,enzymes,et al) into the vascular structure of the liver under certain physical conditions,so as to remove cellular components and retain extracellular matrix and microvascular structure.Cells were reseeded into the decellularized liver scaffold to obtain the recellularized liver,which can be cultured and evaluated in vitro or in vivo by observing the adhesion of seeded cells,detecting the synthesis and secretion of the recellularized liver.Currently,the selection of seed cells,recellularization protocol and recellularized liver transplantation are still under exploration.In this review,the preparation,evaluation,detection and application of the decellularized liver bioscaffold are introduced for the further experimental study and clinical research.

Objective To establish Beagle dogs’model of abducens nerves injury and to observe the clinical therapeu?tic effect of electroacupuncture treatment. Methods Twenty-four Beagle dogs were randomly divided into simple crush group (control group) and crush with electrical stimulation group (experimental group). Cisternal segment of the abducens nerve was given a crush injury, then electrodes were implanted to stimulate the abducens nerve and lateral rectus muscle. Distance between the center of the pupil to medial margin of extraocular adjoin was measured from 1 to 12 weeks after opera?tions. Results All procedures used in the study were well tolerated by Beagle dogs. Electrode implantation to stimulate the lateral rectus muscle and the abducens nerve behind of cavemous sinus was successful. There was no statistical significance of the distance between the two groups from 1 to 2 weeks after operations, and the distance was shorter in experimental group than that in control group from 4 to 12 weeks after operations (P<0.01). Conclusion The animal models established to study electroacupuncture treatment of the injured abducens nerves was successful. Electroacupuncture can promote the re?covery of the injured abducens nerves obviously.

Objective To preliminarily study on the values of microembolic signal(MES)monitoring in the evaluation of anti-Platelet agent or anti-Platelet agent+statins in patients with acute ischemic cerebrovascular disease.Methods Among the patients with acute ischemic cerebrovascular disease in the cm'otid system who performed MES monitoring the MES-positive patients were ramaomly allocated into dual antiplatelet group(aspirin 100 mg/d+clopidogrel 75 mg/d)and dual antiplatelet + atorvastatin goup (aspirin 100 mg/d + clopidogrel 75 mg/d +atorvastatin 20 me4d).MEss were monitored by transcranial Doppler ultrasound.Results Among the 60 patients with acute cerebrovascular disease in the carotid system,13(21.7%)were MES positive.in which,6 and 7 were randomly divided into dual antiplatelet group and dual antiplatelet + atorvastatin group respectively.There were no significant differences in the constituent ratios of sex hypertmsion,diabetes,coronary heart disease,smoking,alcohol consumption,and history of previous stroke as well as the age,time from onset to microembolic monitoring,and time from onset to drug intervention between the 2 groups.There were no significant differences in the numbers of microemboli(8.83±1.17/h vs.9.00±1.83/h)before treatment between the dual alltiplatelet group and dual antiplatdet + atorvastatin group (P=0.851);2 and 7 days after treatment,the numbers of micromixfli were 4.17±1.47 and 2.17±0.75/h respevtively in the dutral antiplatelet group,and they were significantly higher than 1.43±0.976 and 0.71±0.488/h)respevtively in the dual antiplatelet + atorvastatin group (P=0.002 and P=0.003).They were followed up for 8 days;and there were 110 ischemic events in both groups.Conclusions The dual antiplatelet agents or those in combination with statins might reduce the number of MES,but when they were used in combination with statins,the number Of MES reduced more significant.However.because there are only a few patients in the study,this conclusion still needs to be further validatod in a large-scale multicenter randomized controlled trial.The MES monitoring has a certain value in the evaluation of anti-platelet drugs or those in combination with statins

Objective To analyze the plasty of the tip framework and the nasal tip in insufficient-lining cases with auricular and septal cartilage.Methods The tip framework was formed by using septal extension graft (SEG) and columellar strut (CS) to construct the main framework of nasal tip,and then according to the size of the graft the next processes were chosen for supporting structure.When the graft size met the tip position,the caudal margin of the framework could be beyond the maximum stretch position of the lower lateral cartilage and reached or was close to the expected tip position.When the graft size was insufficient,auricular cartilage was used to hold the caudal margin of the framework to extend or to heighten the framework further.Refined plasty of nasal tip was as follows:when the end of framework was higher than or equal to the dome above 3 mm,auricular cartilage strip was used to reconstruct the dome;when less than 3 mm,multilayer onlay grafts were used to heighten the dome.Results From May 2013 to May 2015,42 cases were followed up from 6 months to 18 months.18 cases belonged to the type 1,including 13 cases using ear cartilage to reconstruct dome,5 cases using onlay graft;24 cases belonged to the type 2,including 14 cases using onlay graft and 10 cases using ear cartilage to reconstruct the dome.They all got good results.Conclusions To the insufficient lining cases,the appropriate method can be chosen to form stable tip framework according to the preoperative design and the graft size.Then onlay grafts or dome reconstruction technique is used to form the tip.Most of the insufficient-lining cases can get satisfactory results.

Objective To observe the clinical efficacy of infrared thermal therapy against pseudomonas ae-ruginosa infection on deep partial-thickness burn wound. Methods Forty-three patients in our hospital with main-ly deep partial-thickness burn wound from January 2015 to October 2016 were randomly enrolled to the treatment group(TG,treated with sulfadiazine silver + infrared thermal therapy)and the control group(CG,treated with sulfadiazine silver only). Scores of wound exudation,positive rate of pseudomonas aeruginosa on wound,wound healing rate,wound healing time and overall evaluation of wound healing on the day of 0,3,7,14,21,28 after treatment were conventionally recorded. Adverse effects in TG and CG were also observed. Results (1)Age,sex and burn surface area of patients were found no statistically significant difference between the two groups(P>0.05). (2)On the day of 3,7 and 14,wound exudation score of TG was significantly lower than that of CG(P<0.05);On the day of0,21 and 28,wound exudation score of the two groups were almost same.(3)Positive rate of pseudomonas aeruginosa between the two groups on the day of 7,14 and 21,TG was significantly lower than CG(P < 0.05). (4)Wound healing rate of TG on the day of 7,14 and 21 was higher than CG,which was statistically significant difference in the 2 groups(P<0.05);Wound healing time of TG patients[(21.1 ± 6.5)day]was significantly shorter than that of CG patients[(26.2 ± 6.5)day](P<0.05).(5)Overall evaluation of wound healing of TG was better than that of CG on the day 14 and 21(P<0.05). Conclusions Infrared thermal therapy could reduce the secretion of deep partial-thickness burn wound and effectively control pseudomonas aeruginosa infection. Furthermore,infrared thermal therapy finally improved wound healing rate and shortenedwound healing time of burn wound.

Objective To investigate the changes of serum CXCL16 levels in patients with acute cerebral infarction and their relationship with the Trial of Org10172 in Acute Stroke Treatment (TOAST) etiological types of cerebral infarction. Methods The serum CXCL16 levels in 113 patients with acute cerebral infarction were measured by enzyme-linked immunosorbent assay (ELISA), and they were grouped according to TOAST types. The patients between all the subgroups and/or 32 healthy controls were compared. Results The serum CXCL16 levels in patient group were significantly higher than those in control group (2.29 ± 0.21 ng/mlvs.1.75±0.21 ng/ml, t= 12.863, P= 0.000); The serum CXCL16 levels in large artery atherosclerotic (LAA) stroke group were significantly higher than those in small artery occlusive (SAO) stroke group (2.38 ±0.23 ng/mL vs. 2.21 ±0.11 ng/ml, 1 =5. 743, P =0. 000), and both were significantly higher than those in the control group (q = 20. 501, P = 0. 000; q =13. 527, P= 0. 000). In the LAA group, there were no significant differences between the serum CXCL16 levels in ≥2 artery stenosis group and those in only 1 artery stenosis group (2.34 ±0.24 ng/ml vs. 2.46 ± 0. 19 ng/ml, t = - 1.969, P = 0. 054). Multivariate logistic regression analysis showed that CXCL16 (OR =0.972, 95% CI0.956-0. 978, P =0.001)and hyperlipidemia (OR =3.547, 95%CI 1.160-10. 848, P=0. 020) were the independent risk factors for cerebral infarction. Conclusions The serum CXCL16 levels increased in acute cerebral infarction, it closely related with the occurrence of cerebral infarction, and the LAA stroke group was significantly higher than the SAO stroke group.

Objective To study the expressions of apoptotic protease activating factor-1(Apaf-1)and astrocyte elevated gene-1(AEG-1)in colonic carcinoma,and to explore their correlations with the clinical path-ological features. Methods The expressions of Apaf-1 and AEG-1 were detected in 63 colonic carcinoma sam-ples and 30 normal colonic mucosa adjacent to tumor nest by immunohistochemical method,and their correla-tions with clinical features of colonic carcinoma were analyzed. Results The positive expressions of Apaf-1 and AEG-1 in colonic carcinoma were 23. 81%(15 / 63)and 68. 25%(43 / 63),respectively. The positive expre-ssions of Apaf-1 and AEG-1 in normal colonic mucosa were 76. 67%(23 / 30)and 26. 67%(8 / 30),respec-tively. The positive expression rate of AEG-1 was significantly higher in colonic carcinoma than that in normal tissue(χ2 = 14. 192,P = 0. 000). However,the expression of Apaf-1 was signi-ficantly lower in colonic carci-noma than that in normal tissue(χ2 = 23. 497,P = 0. 000). The expression of Apaf-1 was negatively correlated to the expression of AEG-1(r = - 0. 339,P = 0. 007). The expressions of AEG-1 and Apaf-1 were associated with differentiation degree(χ2 = 4. 643,P = 0. 031;χ2 = 12. 034,P = 0. 001)and clinical stage(χ2 = 6. 628, P = 0. 010;χ2 = 8. 246,P = 0. 004),but they were not correlated with age(χ2 = 1. 462,P = 0. 227;χ2 =2. 401,P = 0. 121)and tumor size(χ2 = 0. 333,P = 0. 564;χ2 = 0. 590,P = 0. 442). Conclusion The expression of AEG-1 is up-regulated in colonic carcinoma,but the expression of Apaf-1 is down-regulated,with a significant negative correlation. Apaf-1 and AEG-1 may be closely related to the occurrence and development of colon carcinoma. Therefore,combination detection of Apaf-1 and AEG-1 may be more valuable for the prog-nosis evaluation of colonic carcinoma.
