Objective] To evaluate the acupuncture treatment of type 2 diabetes peripheral neuropathy clinical curative effect and safety. [Methods] Com-puter retrieval of the CENTRAL, Cochrane, Web Of Science, CBM, CNKI, VIP database, find al about acupuncture and moxibustion treatment of type 2 diabetic gastroparesis of randomized control ed trial(RCT), build library retrieval time until March 19, 2014.At the same time ShouJian into literature references.According to inclusion and exclusion criteria, independently by two researchers after RCT extraction and filtering, data quality evaluation, using Revman5.2 Meta analysis software, use the GRADE system for quality evaluation of evidence. [Results] Seven studies involving 364 patients were includ-ed.Meta analysis showed:(1) effective rate:the acupuncture compared with drugs, the results between the two groups were statistical y significant (RR=3.35, 95% CI=(2.05, 5.48)], suggesting that acupuncture treatment can improve efficiency for the treatment of type 2 diabetes peripheral neuropathy. (2) MNCV:the median nerve, and results showed that the statistical significance was found between the two groups[MD=2.29, 95%CI=(0.61, 3.98)].Includ-ing philalways nervous, the result showed that between the two groups had statistical significance[MD=2.16, 95% CI=(0.16, 4.16)].(3)SNCV:includ-ing median nerve, the results showed that the statistical significance was found between the two groups[MD=1.79, 95% CI=(0.57, 3.02)].Including phi-lalways nervous, the result showed that the two groups had statistical significance[MD=3.59, 95%CI=(2.28, 4.91)].Based on GRADE system ,al the evidence was at low level and weak recommendation. [Conclusion] Acupuncture-moxibustion for the type 2 diabetes peripheral neuropathy is better than the conven-tional medicine treatment.Limited by the guality of the inclusive literalures, it needs more high quality, large sample of RCT further argument.

Resistance to adriamycin was developed in an orignally adriamycin- sensitive strain of Ehrlich ascites carcinoma (EAC) in vivo by treament with the adriamycin during 50 weekly passages of the tumor. The results showed that the growth of the resistant line was slower than that of the EAC, total ascites cell volume,total cell number and mean single-cell volume were significantly smaller of the resistant line than those of original sensitive line. Also, itwas found the homogerously staining region and double minute chromosome in the cells of resistant line. The adriamycin-resistant tumor produced cross resistance to vincristine.mitomycin C,and actinomycin D,while section resistance to VP-16. There was no change in the sensitivity of tumor to oridonin.

Objective To explore the expression of anaplastic lymphoma kinase(ALK) in human ovarian serous adenocarcinoma cell line SKOV3 and to further investigate the effect of crizotinib on SKOV3 cells.Methods The expression of ALK in SKOV3 cells were examined by Western blotting and immunocytochemical methods,and the effect of ALK inhibitor crizotinib on proliferation of SKOV3 cells were evaluated by cell proliferation assay.Results Both Western blotting and immunocytochemical methods showed the expression of ALK in SKOV3 cells.The results of cell proliferation assay suggested that the cell viability of SKOV3 cells was close to 1 when the drug concentration was less than 106 nmol·L-1,and close to 64% when the drug concentration was up to 107nmol·L-1.Conclusion ALK is overexpressed in human ovarian serous adenocarcinoma cell line SKOV3,but SKOV3 cells were insensitive to the therapy of ALK inhibitor crizotinib.

Objective To develop a vulnerable plaque targeting ultrasound contrast agent (UCA) and to evaluate its affinity and imaging performance in vitro.Methods E-selectin receptor-targeting UCA,which conjugated with monoclonal antibody of E-selectin,was prepared with filming-rehydration method and biotin-avidin linkage.The size and distribution of UCA were measured with particle size analyzer,the connectivity condition of microbubbles with E-selectin antibody was also detected with fluorescence analysis.The cytotoxicity from microbubble and ultrasound irradiation was evaluated through cell counting kit-8 (CCK8) assay.The adhesion effect of UCA was assessed after co-incubated with activated mouse endothelial cells (bEnd.3) and compared with that of free antibody intervention group and control group.The imaging performance of UCA at different time points was observed on an ultrasound equipment with a high-frequency transducer.Two-sample t test and one-way analysis of variance were performed to analyze the data.Results E-selectin receptor-targeting UCA was successfully prepared.The cytotoxicity result with CCK8 assay demonstrated the favorable biocompatibility of UCA.The connection amount of UCA on activated bEnd.3 cells ((6.23 ± 0.45) bubbles/cell) was significantly higher than that of the free antibody intervention group ((1.57±0.34) bubbles/cell) and control group ((0.07±0.03) bubbles/cell;F=291.43,P＜0.01).The performance of in vitro ultrasonography at the same time points showed no obvious difference between targeting UCA and control UCA (all t＜0.51,all P＞0.05).Conclusions The prepared E-selectin receptor-targeting UCA has favorable targeting and imaging capabilities.It might be a potentially ultrasound molecular imaging agent for early detection and prognosis evaluation of vulnerable plaque.

Objective: To investigate the feasibility and effectiveness of repairing temporal skin and soft tissue defects and reconstructing sideburns with superficial temporal artery composite perforator flap. Methods: Between January 2018 and January 2019, 12 patients with temporal tumors were treated. There were 5 males and 7 females with an average age of 51 years (range, 37-68 years). There were 8 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma. The disease duration ranged from 3 months to 4 years (mean, 13 months). The area of residual wound after tumor resection was 3.8 cm×2.5 cm-5.2 cm×3.5 cm. The superficial temporal artery composite perforator flap was designed. The hairy superficial temporal artery frontal branch perforator flap was used to repair the hair growing area and reconstruct the sideburn; and the area of the flap was 2.5 cm×1.0 cm-4.2 cm×3.0 cm. And the superficial temporal artery descending branch perforator flap without hair was used to repair the hair-free area; and the area of the flap was 2.5 cm×1.5 cm-7.5 cm×4.0 cm. The donor sites were sutured directly. Results: All flaps survived, and the incisions at the donor and recipient sites healed by first intention. Eleven patients were followed up 6-12 months (mean, 9 months). The incisions were not obvious. The flaps were flat and the color of the flaps were not significantly different from the surrounding skin. The reconstructed sideburns were consistent with the healthy side and the facial appearance was satisfactory. No local tumor recurred during follow-up. Conclusion: For the temporal skin and soft tissue defects involving the sideburn, the superficial temporal artery composite perforator flap can be used to repair subunits with different aesthetic characteristics in sections and has the advantages of operating simply, obtaining satisfied facial appearance, and little effect on the donor site.

Objective To study the effect of radiofrequency ablation (RFA) with sublethal temperature on the production of liver cancer stem cells (LCSCs) and on the expression of LCSCs-related transcriptional factors.Methods Mouse hepl-6 hepatoma cell line and clinical samples of patients with hepatocellular carcinoma (HCC) were used to test the expressions of LCSCs-related markers and transcriptional factors.Results Different temperatures were used to stimulate Hep1-6 cells,and it was proved that the temperature of 45℃ was a sublethal temperature that could not induce cell death.Flow cytometry testing showed that treatment with 45℃ could obviously increase CD13+,CD44+,CD90 and CD133+ Hep1-6 cells,suggesting that treatment with 45℃ could increase the production of above mentioned types of LCSCs in hep1-6 cells.Real-time quantitative polymerase chain reaction (RT-qPCR) assay indicated that the temperature of 45℃could cause significant increase in CD13,CD90 and CD133 mRNA.In all 5 HCC patients,CD13 mRNA in the recurrent HCC lesions was remarkably increased,CD133 mRNA was increased in 4 patients with recurrent HCC,and CD90 mRNA was increased in only one patient with recurrent HCC.Flow cytometry testing revealed that CD13+ LCSCs were strikingly increased in 4 recurrent HCC patients,while CD133+LCSC was increased in only one patient,suggesting that more close correlation existed between the increase of CD13+ LCSCs and the temperature of 45℃.RT-qPCR assay showed that in 4 recurrent HCC patients with increased CD13+ LCSC,the Sox2 and Stat2 among 13 LCSCs-related transcriptional factors were obviously increased.Flow cytometry testing showed that 45℃ treatment also increased the expression of Sox2 and Stat1 mRNA in Hep1-6 cells.Finally,Sox2 and Stat1 could be knockdown by siRNAs,indicating that both Sox2 and Stat1 transcriptional factors were involved in 45℃-induced production of CD13+ LCSCs in Hep1-6 cells.Conclusion In RFA therapy,the use of sublethal temperature of 45℃ can increase CD13+LCSCs,which is related to the promotion of Sox2 and Stat1 expression.The results of this study can be used for reference in the research of liver cancer recurrence.
