ObjectiveTo investigate the effects of induction with Dezocine to prevent the agitation of the patient after remifentanil anesthesia.Methods60 patients of upper abdominal surgery,ASA Ⅰ ~ Ⅱ class,were randomly divided into 3 groups,20 patients in each group,anesthesia was induced with the midazolam 0.05 mg/kg,propofol 1 ~2mg/kg,vecuronium 0.12mg/kg.Analgesic drugs were administer as follow:control group,remifentanil ( group Rmf )1 μg/kg; fentanyl group ( group F) 4 μg/kg; Dezocine group ( group D) 0.2mg/kg.Remifentanil、propofol are used to maintain anesthesia.The time of recovery and extubation,the VAS pain score,the Ramsay score and adverse reactions such as vomiting,respiratory depression after extubation were recorded.ResultsCompared with group Rmf,the hemodynamic parameters was more stable in group F and group D.Compared with group F ( 1 μg/kg),the VAS pain score,the Ramsay score and adverse reactions significantly decreased in group D ( P < 0.05 ),and the time of extubation in group F was longer than group D(P < 0.05).Conclusion0.2mg/kg of Dezocine could be used for the induction of anesthesia to reduce the incidence of agitation and adverse reactions during recovery period.

MicroRNA (miRNA) is a class of endogenous,single-stranded non-coding small RNA that contains 21 to 23 nucleotides and is widely distributed in eucaryon,miRNA plays an important regulatory role in cell proliferation,apoptosis,growth and development through the regulation of gene translation after transcription and expression,miRNA has a close relationship with pathogenesis and development of hepatocellular carcinoma.And in this process,part of miRNA acts as oncogenes or tumor suppressor genes.A number of miRNA,such as miR-30d,miR-221,miR-222 and miR-101,had been found to express abnormally in hepatoeellular carcinoma.Here we summarize the related progress in research of miRNA and hepatocellular carcinoma.

Objective To establish a simple , practical , highly-effective and stable method for the isolation and cultivation of rat hair follicle cells. Methods Under sterile condition, single hair follicle was taken out after the skin around the barbel of SD neonatal rats was sheared off. And then the hair follicles were digested with two-step method with Type Ⅰcollagenase and trypsin. The obtained cell suspension was planted into the culture plate which was covered with extracellular matrix, and then was cultivated with K-SFM culture medium containing fetal bovine serum with volume fraction of 1%. On the next day, K-SFM culture medium was replaced with serum-free culture medium. The remaining tissues were cut into pieces and spread out in the culture flask, and then were cultivated with HG-DMEM culture medium containing serum. Two kinds of cells were harvested and then were identified by immunofluorescence. The hair follicle epithelial cells were tested by flow cytometer. Results The hair follicle epithelial cells obtained through the above methods showed rapid adherence, and were round or polygon-like , with typical cobblestone-like morphology. The long spindle-shaped cells were seen around the tissues cultivated, having many protrusions on the surface of the cells, and they were interconnected into reticular structure. The expression of cytokeratin 15, cytokeratin 19 and β1 integrin in epithelial cells were positive. Most of the epithelial cells were in the G1 phase, accounting for 75.6%. The expression of laminin ( LN), fibronectin ( FN) and vimentin in the connective tissue sheath cells were also positive. Conclusion The cells harvested by modified two-step enzyme digestion method have confirmed as hair follicle cells and fibroblasts, and the obtained cells are of rapid adherence, good homogeneity, and active proliferation.

Objective To explore the feasibility of repairing skin defect with Pelnac tissue engineering skin and cultured epidermal stem cells ( ESCs) and fibroblasts. Methods ESCs and fibroblasts in SD rats were isolated and cultured in vitro, and then were detected by immunohistochemistry. Fibroblasts were seeded in Pelnac material to construct dermis, and ESCs were seeded on the surface of dermis to construct tissue engineering skin. Thirty BALC/c nude mice were randomly divided into groups A, B and C. After mouse back skin defect model was established, group A was transplanted with Pelnac material, group B was transplanted with compound of Pelnac and fibroblasts, and group C was transplanted with Pelnac tissue engineering skin. The wound healing was observed after operation. The wound tissues were sampled for pathological histology test on the 5th and 7th day after transplantation. Results The expression of cytokeratin 15 and β1 integrin in ESCs was positive, and the expression of laminin ( LN) and fibronectin ( FN) in fibroblasts was positive. In group C, the wound healing of nude mice was the best, characterized by the proliferation of fibroblasts, obvious new capillaries and regularly arranged epidermal cells at the transplantation sites. Conclusion Pelnac tissue engineering skin has good effects on promoting repair of skin defect of nude mice.

Journal of Practical Obstetrics and Gynecology 2017;33(3):206-209
Objective:To detect the expression of ALDH1 and ABCG2 in the specimens from different levels of cervical lesions.Methods:Use SP immunohistochemistry to detect the expression of ALDH1 and ABCG2 in 76 cases of cervical squamous cancers,52 cases of HSIL,and 37 cases of chronic cervicitis tissues,and analyze the results.Results:①The positive expression rates of ALDH1 and ABCG2 in chronic cervicitis tissues were 5.41% (2/37) and 8.11% (3/37),in HSIL tissues were 23.08% (12/52) and 28.85% (15/52),and in cervical cancers tissues were 53.95% (41/76) and 61.84% (47/76),respectively.The positive expression rates in cervical cancers tissues were significantly higher than in HSIL and Cc hronic cervicitis tissues,(P < 0.05).②The positive expression of ALDH1 in cervical cancer tissues had correlation with tumor grade and lymphnode metastasis (P <0.05),while the positive expression of ABCG2 in cervical cancer tissues had correlation with tumor grade,clinical stage and lymph-node metastasis(P <0.05).③The expressions of ALDH1 and ARCG2 in cervical cancer were positive relative(r =0.535,P < 0.05).Conclusions:The increased expressions of ALDH1 and ABCG2 in cervical squamous cancer may play a role in the occurrence,development and metastasis of cervical squamous cell carcinoma.ALDH1 and ABCG2 may have synergistic effect in occurrence of cervical cancer.
