Objective To discuss the influencing factors of intracranial cerebral hemorrhage complicationin patients with acute ischemic stroke (AIS) after receiving Solitaire AB stent mechanical thrombectomy.Methods The clinical data of 32 AIS patients,who were treated with Solitaire AB stent thrombectomy during the period from June 2015 to October 2016 at authors' hospital,were retrospectively analyzed.The basic materials of patients,who developed intracranial hemorrhagic transformation (HT) after Solitaire AB stent thrombectomy,were analyzed and compared with the results of related studies published at home and abroad.Results Solitaire AB stent thrombectomy was successfully accomplished in all the 32 AIS patients.The postoperative fatality rate was 9.4％ (3/32).Three patients developed symptomatic intracranial HT after Solitaire AB stent thrombectomy,including artery occlusion in anterior circulation (n=1) and artery occlusion in posterior circulation (n=2),with the HT incidence being 9.4％ (3/32).Of the 3 patients,conservative treatment was adopted in 2 and ventricular external drainage with implantation of liquid storage bag through ventricular drilling-hole was carried out in one.Finally,2 patients died of HT and one patient recovered by conservative treatment.The percentage of HT death patients in all deaths was 66.7％ (2/3).Conclusion Intracranial HT is a fatal complication of embolectomy in AIS patients.In clinical practice,the indications of thrombectomy should be strictly observed,besides,intraoperative fine manipulation and sandardized perioperative management are also very important to reduce the incidence of bleeding complications.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

Objective To explore the concept,denomination and technique of miniature tissue transplantation in hand clinic. Methods In 537 cases,local skin or composite tissue defect in 756 thumbs or fingers were repaired with 4 kinds of miniature island flap and 10 kinds of miniature vascularized composite tissue.Some of them were created in clinic practice.The precess,main points and indication of the operation were expounded and compared. Results In 639 fingers covered with miniature island flap,the transferred flaps were surviverd completely in 621 fingers(97.2%),survivered partly in 11 fingers(1.7%)and necrosised in 7 fingers(1%).In 117 fingers repaired with miniature vascularized composite tissue,all the transplanted tissues were survivered.In all the injuried fingers,beautiful outlook were recovered and no fat and clumsy were found,two-point difference was 6-8 mm,effctive sensibility and good function were restored,and all the patients were satisfied. Conclusion Miniature tissue transplantation were good methods to cover the local defect in fingers or thumbs,worth of generalization and aplication in hand clinic,and have an important significance for improve the trauma repair quality and treatment level in hand surgery.

Objective To investigate the effects of Longdan Xiegan Decoction on the expression of Notch signaling-related genes in rats with experimental autoimmune uveitis (EAU).Methods Totally 24 Lewis rats were randomly divided into normal control group,EAU model group and Longdan Xiegan Decoction treatment group.A rat model of EAU was established in the EAU model group and Longdan Xiegan Decoction treatment group,followed by intragastrical administration of Longdan Xiegan Decoction in the latter group after successful modeling.On day 12 after different treatments,the spleen and lymph nodes were isolated from rats of all the three groups for the collection of CD4 + T ceils,and the levels of both Th17 and Treg cells were analyzed by flow cytometry to calculate the ratio of Th17 to Treg cells.Meanwhile the levels of Notch1,Notch2,Notch3,Notch4 mRNAs expression were monitored by qRT-PCR.Moreover,the expressions of Notch signaling-related proteins were further detected using ELISA technique.Results Flow cytometry showed increased Th17 cell level but decreased Treg cell level in the EAU model group when compared with the normal control group.However,after treatment with Longdan Xiegan Decoction,the Th17 level was decreased,whereas the Treg level was increased,and the ratio of Th17 to Treg gradually restored to equilibrium when compared to EAU model group.qRT-PCR results showed that the expression levels of Notch1,Notch2 and Notch4 mRNAs in Longdan Xiegan Decoction treatment group were significantly higher than those in the normal control group (all P ＜ 0.01),but lower than those in EAU model group on day 12 after treatment (all P ＜ 0.01),without Notch 3 expression in the spleen and lymph nodes.In addition,Notch 1,Notch 2 and Notch 4 protein levels of the spleen and lymph nodes in Longdan Xiegan Decoction treatment group showed the similar tendency as compared to those of Notch 1,Notch 2 and Notch 4 mRNAs (all P ＜ 0.01),and the expression of Notch 3 protein was still not observed.Conclusion Longdan Xiegan Decoction can effectively relieve the imbalance of Th17/Treg cells in EAU rats,and its mechanism may involve the differentiation of naive CD4+ T cells into Th17 and Treg cells,which is regulated by Notch signaling.

Objective To investigate the regulatory roles of rno-miR-30b-5p in the expression of Atg5,Atg12 and Becn1 autophagy genes and their expressions in rats with experimental autoimmune uveitis (EAU).Methods Application of dual luciferase report system was conducted to detect the regulatory roles of rno-miR-30b-5p in Atg5,Atg12 and Becn1 gene expression.Lewis rats were randomly divided into control group and EAU group,with 6 rats in each group.Next,rats in EAU group were immunized to establish EAU model.After treatments,Genesis-D fundus camera was used to observe the fundus inflammation every day.After immunization for 12 days,the pathological features of rat ciliary body and retina were detected,and meanwhile,the spleen and lymph nodes in both groups were isolated to detect the expressions of rno-miR-30b-5p,Atg5,Atg12 and Becn1 genes by quantitative PCR (Q-PCR);the levels of autophagy related proteins were determined by ELISA.Results Dual luciferase report gene expression assay confirmed that Atg5,Atg12 and Becn1 were target genes of rno-miR-30b-5p.Twelve days after immunization,compared with the control group,rats in the EAU group had severe iris adhesions and severe blood vessel swelling,and pathological examination revealed massive infiltration of inflammatory cells in the ciliary body and retina.Furthermore,rno-miR-30b-5p mRNA was 0.46 ±0.01,0.29 ±0.17in the spleen and lymph nodes in EAU group,respectively,which was down-regulated when compared with the control group (P ＜0.01);whereas the expressions of Atg5,Atg12 and Becn1 were significantly upregulated,and the differences were statistically significant (all P ＜ 0.05).ELISA results showed that Atg5,Atg 12 and Becn 1 protein expression levels in the spleen and lymph nodes in EAU rats were significantly higher than those in the control group (all P ＜ 0.05).Conclusion rno-miR-30b-5p can regulate the expressions of Atg5,Atg12 and Becn1 autophagy-related genes.The down-regulation of rno-miR-30b-5p expression in the spleen and lymph nodes in EAU rats can significantly up-regulate the expressions of Atg5,Atg12 and Becn1 genes,thereby regulating the pathogenesis of uveitis.

This study was aimed to find a better method to isolate and enrich mesenchymal stem cells (MSCs)from bone marrow between CD271 (low affinity nerve growth factor receptor, LNGFR) and CD133 used for immunomagnetic positive selections through comparison of characteristics of MSCs isolated by these two agents. CD271+ and CD133+ cells were isolated from bone marrow and their colony forming unit-fibroblast (CFU-F) efficiency and proliferative capacity were assessed. Cell surface phenotype, adipogenic and osteogenic inductions were also assayed on the cells (after passage 3) isolated by both methods. The results showed that the purities of immunomagnetically selected CD271+ and CD133+ cells were (89.50+/-0.98)% and (88.03+/-3.06)% respectively. The CFU-F median frequency of CD271+ cells was 3 times as high as that of CD133+ cells, no CFU-F was observed in CD271- cells, while a few CFU-F was found in the CD133- cells. Phenotype of cells (after passage 3) isolated by the two methods was same, that is CD34-, CD14-, CD45-, CD90+, CD29+, CD44+, CD105+, CD73+. CD271+ cells possessed faster proliferation and stronger osteogenic and adipogenic differentiation potential than that of CD133+ cells. It is concluded that as compared with CD133 positive selection, CD271 positive selection is a better method for isolating and enriching mesenchymal stem cells from bone marrow.
