BACKGROUND:Neural stem cel (NSC) transplantation is a common method for various ischemicencephalopathies, but inability to survive in the transplantation region limits its further use in clinical practice. OBJECTIVE:To explore the effect of vascular endothelial progenitor cel s (VEPCs) on the proliferation and apoptosis of co-cultured NSCs as wel as vascular remodeling in rats with ischemia reperfusion injury. METHODS:125 Sprague-Dawley rats were randomly divided into five groups, 25 rats in each group, including sham operation, ischemia, NSCs, co-culture, and VEPCs groups. Rat models of ischemia reperfusion injury were made in al groups except for the sham operation group, fol owed by corresponding interventions. The proliferation and apoptosis of neural stem cel s were detected, and vascular remolding in the ischemic region was observed in each group. RESULTS AND CONCLUSION:At different time points after transplantation, BrdU positive cel s were not observed in VEPCs, ischemia and sham operation groups;the number of BrdU positive cel s in the co-culture group was significantly higher than that in the NSCs group (P<0.05);BrdU+/Caspase-3+cel were observed in both co-culture and NSCs groups, and the apoptosis rate of the co-culture group was significantly lower than that in the NSCs group (P<0.05);there were new blood vessels in al the groups except for the sham operation group, and the number of new bone vessels was highest in the co-culture group. To conclude, our experimental results show that VEPCs promotes the proliferation of co-cultured NSCs, inhibits cel apoptosis and and promote angiogenesis in the ischemic penumbra of rats with ischemia reperfusion injury.

BACKGROUND:Mkx (Mohawk, transcription factor) is one of the crucial factors in tendon formation, development and differentiation.
OBJECTIVE:To summarize the molecular structure, distribution and function of Mkx and its research process in the signaling pathways during tendon differentiation.
METHODS:The first author retrieved the databases of CqVip, CNKI and Medline from1990 to 2016 using the keywords of“Mkx, Mohawk, Irxl, tendon, tendon differentiation, tissue engineering, TGFβ, stem cel”in Chinese and English, respectively. The articles related to research process of Mkx in tendon tissue engineering were retrieved, and a total of 55 literatures were enrol ed final y.
RESULTS AND CONCLUSION:Mkx that expresses in various mesoderm-derived tissues plays an important role in the formation and development of tendon and tissue-engineered tendon formation. Although Mkx does not directly act on Scx (Scleraxis), it can regulate the differentiation of tendon progenitor cel s via transforming growth factor-β2 signaling pathway. Cel s from different species and different cel lines as wel as various cytokines for certain make different effects on Mkx involved in tendon tissue engineering.

Objective To observe the effect of polydatin on nerve cell apoptosis and the influence of the caspase-8 and FLIP protein expression after ischemia reperfusion injury. Methods Thirty rats were randomly divided into sham operation group, model group and polydatin group. The middle cerebral artery occlusion (MCAO) model of focal cerebral ischemia was established by the method of thread embolism. Rats were subjected to adaptive feeding for the first 7 days and then recieved the treatment for another 10 days. The model of ischemia reperfusion injury was established at the 14th day. The polydatin group received 15 mg/kg of polydatin, and the sham operation group and the model group with the same volume of saline once a day for 15 days. The expression of caspase-8 and FLIP protein in the hippocampus of rats were observed by immunohistochemical staining. The expression of caspase-8 and FLIP protein in the hippocampus of rats were observed by TUNEL method at 72 h after cerebral ischemia-reperfusion. Results Compared with the model group, the number of apoptotic cells of polydatin group significantly decreased in hippocampus CA1 region (P<0.01); The expression of caspase-8 (148.78 ± 6.82 vs. 89.61 ± 7.76) in the polydatin group significantly decreased and the expression of FLIP (127.60 ± 8.52 vs. 150.22 ± 8.53) in the polydatin group was increased significantly in hippocampus CA1 region(P<0.01). Conclusions Polydatin have a protection effect on ischemia reperfusion injury in rats and its mechanism may be inhibition of caspase-8 protein expression, promote the FLIP protein expression.

Objective To explore the effect of infrared ray treatment on improving fat granules survival rate and reducing postoperative complications in autologous fat transplantation. Methods The patients who received autologous fat transplantation were divided into infrared ray group and control group.Each group was further divided into breast group and face group. These cases in infrared ray group were radiated for 30 minutes with infrared ray 24 hours later after surgery, once a day for sequential 5 days.No treatment was given to the control group. The survival status and complication were observed and statistically analyzed. Results Infrared ray treatment could increase fat granules survival rate after autologous fat transplantation, but no significant effect was acheived on reducing complications. Conclusion Infrared ray treatment is an effective way to enhance the survival rate of fat granules.

Objective: To improve the understanding of pulmonaryStrongyloides stercoralis. Methods: Two paients were diagnosed with severe infection with pulmonaryStrongyloides stercoralis by respiratory ICU of Xiangya Hospital. The clinical manifestations, laboratory tests, imaging and pathological data were analyzed. Another 87 cases in the literature were reviewed from 1973 to 2013. Results: In the 2 cases, digestive symptoms were the ifrst symptom andStrongyloides stercoralis was found in the lungs. Eosinophils was detected in the 13 death cases by blood routine examination, with 10 cases≤0.05×109/L. Conclusion: The farmers were the main infected people. Patients with basic diseases or with immunosuppression due to long-term glucocorticoid treatment tend to infect and even die atfer the infection withStrongyloides stercoralis. Eosinophil granulocyte reduction shows poor prognosis, which needs early diagnosis and treatment.

Objective:To examine the expression and function of thrombonspondin-1 (TSP-1) in oxygen-induced retinopathy in new-born mice, and to investigate its role in retinal neovascularization. Methods:A total of 40 C57BL/6J newborn mice were divided equally into a model group (n=20)andanormalcontrolgroup(n=20).Miceinthemodelgroupwereexposedto75%oxygentoestablish the oxygen-induced retinopathy (OIR) model. On the 7th, 9th, and 11th day after the birth of mice, 5 mice were randomly selected each time from the 2 groups to examine the expression of TSP-1 mRNA with reverse transcription polymerase chain reaction (RT-PCR). After that, 5 mice were selected on the 11th day to observe the retinal neovascularization by fluorescein angiography retinal flatmount. Results:On the 11th day, fluorescein angiography retinal flatmount showed that the retinal blood vessels presented mean network distribution in the normal control group, while in the model group, a lot of dilatated areas in the retinal main vessels surrounded the optic disc. Meanwhile lots of new blood vessels were found surrounding the optic disc with irregular distribution but well distributed peripherial retinal small vessels, which was typical of early stage OIR. There was no signiifcant difference in the retinal TSP-1 mRNA level between the model group and the normal control group in the postnatal 7-day mice (P>0.05). Compared with the normal control group, the expression of TSP-1 mRNA in the model group was signiifcantly lower in postnatal 9-day and 11-day mice (P<0.05, P<0.01) , and the expression of TSP-1 mRNA in postnatal 9-day mice was lower than that in the postnatal 11-day mice(P<0.05).
Conclusion:In the early stage of OIR model (retinal vascular growth and development stage), the expression of TSP-1 mRNA in the retinal tissue is gradually decreased, implying that TSP-1 (as a negative regulatory factor) may be involved in the formation of retinal neovascularization in the early stage.
