Objective By reviewing the relevant literature, we explored the current status and problems of the evaluation of the training effectiveness, and put forward the corresponding countermeasures, in order to provide a theoretical basis for the effect evaluation of nurse training in China. Methods By searching Citation online search and integration system (CITE), the Chinese biomedical literature service system (CBM), we included the literatures on the effect evaluation of the nurses training in the core journals from January 2006 to November 2015. Retrieval literatures were imported the bibliographic management software Note express by database. The corresponding field were analyzed in the literature′s age distribution, evaluation object, evaluation model, evaluation method, evaluation index and evaluation tool, et al. Results There were 343 literatures had retrieved, the total number of literatures presented a increasing tendency. The evaluation methods, evaluation tools and evaluation indicators presented a tendency of diversity, and the evaluation model was relatively single. Only 16 (4.7%) literatures tried to construct the training effect evaluation system of nurses, which was not based on some theory or hypothesis, which had not been effectively put into practice. Conclusion The effect evaluation system of nurse training needed to be done in depth, such as reconstruction of the new training evaluation model, the establishment of training evaluation system of different professional, different levels, different positions, to research evaluation methods, evaluation criteria and clinical practice testing, to design, training evaluation management software etc.

ObjectiveTo investigate the therapeutic effect of human umbilical cord mesenchymal stem cell-paracrine substance on fulminant hepatic failure (FHF) rat, and to study the effect on liver function and hepatocyte proliferation. MethodsMesenchymal stem cells(MSCs)were separated from human umbilical cord, and surface makers of cells were detected by flow cytometry. Human umbilical cord mesenchymal stem cells-conditioned medium(MSC-CM) was prepared. FHF rat model was induced by intraperitoneal injection of D-galactosamine and they were randomly diveded into three groups: MSC-CM group, NS group, PHGF group. 24 h later, 1 ml MSC-CM, 1 ml 0. 9% NaCl solution and lml PHGF solution was injected into the tail vein of MSC-CM, NS, and PHGF rats, respectively. In each group (n=8 per group), blood samples were collected at 12, 24, 36, and 60 h after treatment from inner canthus for analysis of blood ALT and TBIL levels. We used five rats per group for tissue collection after sacrifice at 36 h after treatment and 10 animals per group for survival analysis. PCNA immunohistochemical staining was used in the sections of liver tissue to detect hepatocyte proliferation. Results24 h after treatment, the levels of ALT and TBIL in the MSC-CM and PHGF groups were lower than those in the NS group(P＜0. 05), but there was no significant difference between the MSC-CM and PHGF groups. There were more PCNA-positive hepatocytes in the MSC-CM and PHGF groups than in the NS group(P＜0.01), but there was no significant difference between MSC-CM and PHGF group. Survival analysis found that the survival rate of rats in the MSC-CM and PHGF groups was higher than that of rats in the NS group (P=0. 049), but there was no significant difference between the MSC-CM and PHGF group. ConclusionsThe paracrine substance of human umbilical cord mesenchymal stem cells can stimulate hepatocyte proliferation and improve liver function of FHF rats, potentially creating a new avenue for the treatment of FHF.

Depression is a common cause of human disability and death.Some patients are not sensitive to antidepressants,and also the recurrence rate is very high.Unfortunately,there are many problems with existing antidepressants.So,it is urgent to find a new antidepressant aiming at multiple targets.Recently,researchers have found that soluble N-ethylmaleimide-sensitive factor attachment protein receptor(SNARE)complex is closely related to the progression of depression.This review discusses the potential mechanisms of the SNARE complex in glial cells,and hopes to contribute to the understanding of depression and provide new ideas for clinical development of novel antidepressant drugs.

Objective The study aims to optimize the conditions for constructing orthotopic nude mouse models of liver cancer by injecting human liver tumor cell lines and to explore appropriate timings for drug administration. Methods Human hepatocellular carcinoma Hep3B and hepatoblastoma HepG2 cell lines, which stably expressing the luciferase reporter gene (LUC), were selected. The linear correlation between the luciferase luminescence intensity and the number of liver tumor cells was analyzed using a Small Animal In Vivo Imaging system to verify the luminescent efficiency of the human liver tumor cells. Different concentrations (8×10⁶, 2.4×10⁷, 7.2×10⁷ cells/mL) and resuspension media (PBS, Matrigel) of human liver tumor cell suspensions HepG2-LUC and Hep3B-LUC were orthotopically inoculated into the liver lobes of 5-week-old female BALB/c nude mice (12 groups, 7 mice each) to construct human liver tumor nude mouse orthotopic cancer models. Every 7 days, the weights of mice were recorded, and the growth of orthotopic tumors was monitored using the Small Animal In Vivo Imaging system. On day 35 post-cell inoculation, mouse livers were dissected, and pathological slices were prepared for HE staining to observe histopathological changes in liver tissues. Results The luminescence intensity of human liver tumor cell lines was positively correlated with the number of cells (R²=0.983 1, R²=0.970 5), indicating their suitability for orthotopic model construction. Successful modeling was achieved in the high-concentration groups of HepG2-LUC, the low-, medium-, and high-concentration groups of HepG2-LUC+Matrigel, the medium- and high-concentration groups of Hep3B-LUC, and the low-, medium-, and high-concentration groups of Hep3B-LUC+Matrigel. For both HepG2-LUC+Matrigel and Hep3B-LUC+Matrigel groups, mice in the high-concentration groups exhibited significantly reduced body weight compared to the low- and medium-concentration groups (both with P<0.05). The luminescence intensity of successfully modeled mice increased exponentially over time (R²>0.950 0), and reached a minimum of 1.0×10⁷ p/(s·cm²·sr) by day 14 post-transplantation. Mice in the low- and medium-concentration groups of HepG2-LUC and the low-concentration group of Hep3B-LUC showed no significant pathological changes, while the other groups exhibited evident liver tumors and hepatocyte lesions. Conclusion For the HepG2-LUC cell line, the recommended injection volume is 50 µL with a cell density of 2.4×10⁷ cells/mL, resuspended with Matrigel, followed by drug administration or prognostic measures on day 7 post-modeling. For the Hep3B-LUC cell line, the recommended injection volume is 50 µL with a cell density of 7.2×10⁷ cells/mL, not resuspended with Matrigel, with administration or prognostic measures on day 14 post-modeling.

OBJECTIVE: To assess the value of chromosomal karyotyping analysis and single nucleotide polymorphism-based microarray (SNP-array) for the detection of chromosomal mosaicisms in amniotic fluid samples. METHODS: Seventy four pregnant women with fetal mosaicisms detected by both methods were retrospectively analyzed. RESULTS: Among the 74 mosaicisms, 12 were pseudo and 62 were true mosaicisms, which included 1 Robertsonian translocation, 3 deletions, 4 supernumerary markers, 19 autosomal aneuploidy mosaicisms, 30 sex chromosome aneuploidy mosaicisms and 5 isometric chromosome mosaicisms. CONCLUSION Chromosome karyotyping analysis and SNP-array have their own advantages and limitations for the diagnosis of mosaicisms. When the two methods have yielded inconsistent results, fluorescence in situ hybridization may be used for further verification.
