Objective To explore the Kano model analysis in the application of midwife outpatient service quality management. Methods Kano questionnaire was consisted of 24 items, including five parts, environment facilities, service evaluation, service technology, the team service, delivery service′quality. Using the Kano model analysis, the impact factors of the midwife outpatient service quality in five different quality attributes were determined. It included property and had the opposite answer to the question, charisma, essential properties and one property. Results By identifing the quality index classification of the pregnant women with satisfactory service quality to midwife outpatient service, attributable to a property were 1,2,3,4,8,9,10,14,20,21;attributable to mandatory attributes were 13, belonging to the charm of the property had 5,6,7,11,12,15,16,17,18,19,22,23,24. Midwives outpatient had most of charisma attribute, 54.2%(13/24) of the total;The second was one attribute, 41.7% (10/24) of the total. The technology level of midwife was essential attribute. Conclusions Kano mode analysis technology will be introduced to the midwife outpatient service quality management to provide decision reference for improving the quality of the hospital management level, improve maternal satisfaction, improve the obstetric operation efficiency.

OBJECTIVE To investigate the effect of subcutaneousimmunotherapy(SCIT) on levels of the serum human beta defensin-2 in children with allergic rhinitis. METHODS 30 cases of children with allergic rhinitis who were treated by SIT were selected as the treatment group, 20 cases of healthy children as the control group. Serum HBD-2 concentration of the control group was tested. Serum HBD-2 concentration of the treatment group was tested at three different time points: before SCIT, half a year after SCIT and one year after SCIT. And total nasal symptom scores(TNSS) and medication scores were recorded at each time point. RESULTS The serum HBD-2 concentration of the control group, that of the treatment group before SIT, half a year after SIT and one year after SIT were 4.62[4.08; 4.87], 3.74[3.37; 4.61], 4.62[4.13; 5.54], 4.79[4.45;6.19]ng/ml. The HBD-2 concentration gradually increased after SCIT. The TNSS of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 7.43±2.15, 4.17±2.16, 4.20±1.92, The medication scores of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 1.25[0.75; 1.38], 0.25[0; 0.75, 0.25[0; 0.75].There was no correlation (all P>0.05) between the serum HBD-2 concentration and TNSS or medication scores of the treatment group. CONCLUSION The serum levels of HBD-2 in patients with allergic rhinitis were lower than those in normal persons. The specific immunotherapy raised the serum HBD-2 levels of allergic rhinitis patients.

Objective To analyze the clinical and biological characteristics of adult acute T-lymphocytic leukemia (T-ALL) patients carrying SET-NUP214 fusion gene,and the prognostic value of SET-NUP214 molecular marker monitoring.Methods The clinical and laboratory data of 4 adult T-ALL patients with SET-NUP214 fusion gene in the Third People's Hospital of Chengdu from January 2009 to December 2014 were analyzed retrospectively,and T cell receptor (TCR) gene rearrangement was detected to judge the differentiation and developmental stages of tumor cells in these patients.Minimal residual disease (MRD) was detected in 2 patients with follow-up specimens through detection of SET-NUP214 gene by using polymerase chain reaction.Results Four patients expressed T cell immune markers CD5,CD7,and cytoplasmic CD3 (cyCD3),and also expressed some myeloid-specific antigens.All 4 patients had the same SET-NUP214 fusion site.In the tumor cells of 4 patients,5 TCRB gene rearrangements were detected,all of which were incomplete rearrangement of DB-JB;4 patients were detected with TCRG and TCRD gene rearrangements,and all were completely rearranged.The result of MRD monitoring through SET-NUP214 fusion gene was consistent with clinical treatment outcome.Conclusions The T-ALL patients with SET-NUP214 fusion gene have some unique cell biological characteristics.SET-NUP214 fusion gene could be used as a molecular marker for MRD monitoring,and which can be used for the follow-up in the course of treatment.

OBJECTIVETo explore the expression of hsa-mir-186 in colorectal cancer and study its role in regulating the biological behaviors of human colorectal cancer SW620 cells in vitro.

METHODSThe expression of hsa-miR-186 in colon cancer tissue and the adjacent tissues as well as 5 colon carcinoma cells were analyzed using real-time quantitative RT-PCR. The precursor sequence of miR-186 gene was amplified from the genomic DNA by PCR and cloned into the lentiviral vector PLVTHM labeled with GFP. The colorectal cancer cell line SW620 was transfected with PLVTHM-miR186 vector and the lentivirus-infected cells were sorted with flow cytometry. Cell counting kit-8 (CCK-8) assay was used to detect the proliferation of the cells. The migration and invasion of SW620 cells were investigated using Transwell assay and scratch test. Western blotting was used to detect the expression of YY1 protein in SW620 cell lines.

RESULTSThe relative expression of miR-186 in the cancer tissues was 0.0024∓0.0027, significantly lower than that in the adjacent tissues (0.066∓0.068, P=0.008); the relative expression level of hsa-miR-186 in SW620 and LoVo cells with a high metastatic potential was 0.118∓0.138 and 0.157∓0.001, respectively, significantly lower than that in HT-29 cells with a low metastatic potential (1.000∓0.00, P<0.05). The recombinant lentiviral vector PLVTHM-miR186, verified by enzyme digestion, sequencing and qPCR, caused significant inhibition of cell proliferation, migration and invasion and suppressed the expression of YY1 protein in SW620 cells.

CONCLUSIONAs a tumor suppressor gene, Hsa-miR-186 is down-regulated in colon carcinoma tissues and in highly metastatic SW620 and LoVo cells. Has-miR-186 can inhibit the cell proliferation, migration and invasion of colon carcinoma cells in vitro possibly by suppressing YY1 expression.

Bats are important reservoir animals and more than 60 viruses have been identified in bats with many of them highly pathogenic to human. In order to understand the natural background, genetic diversity of bat viruses in China and discover potential viral pathogens, Solexa sequencing based viral metagenomics focusing on bats tissues was established and to analyze the virome of bats collected from Jilin, Yunnan and Hunan province. By Solexa sequencing, 116 442 324 useful reads were obtained and assembled into 4 872 contigs, of which 8.2% (4 002/4 4872) were annotated to 36 viral families, including 19 vertebrate virus families, 6 plant virus families, 4 insect virus families and 4 phages. Further contigs analyses showed that some adenovirus, bocavirus, picobirnavirus, parvovirus contigs sequences were similar with known viruses. However, part of them shared limited identities to these viruses implying the discovery of new viruses. Moreover, PCR validation of adenovirus and bocavirus confirmed the results obtained by viral metagenomics. This study aimed to understand bat virome in China by viral metagenomics and could be helpful to establish effective surveillance on wildlife-associate zoonoses.

PI3K/AKT/mTOR signaling pathway plays a crucial role in cell proliferation, survival, differentiation, motility and intracellular transport. PI3Kδ, an isoform of PI3K, is highly expressed in B lymphocytes and is involved in the malignant progression of B-cell lymphoma. Thus, PI3Kδ has emerged as an attractive target for the development of anti-B-cell lymphoma drugs. Currently, there are several PI3Kδ inhibitors approved by the FDA for the treatment of B-cell lymphoma, each with its own characteristics, but also with varying degrees of adverse effects in clinical practice. Due to the complexity and diversity of the pathogenesis of B-cell lymphoma, single-target PI3Kδ inhibitors often have limited efficacy and are prone to drug resistance, and need to be combined with chemotherapy or other targeted drugs to enhance their efficacy. The future trend is to design novel inhibitors with higher efficacy and lower toxicity or to develop novel combination regimens with other chemotherapy, radiotherapy, and target drugs to acquire better anti-tumor effects with reduced adverse effects. This review summarizes the PI3Kδ inhibitors that have been approved for the treatment of B-cell lymphoma or are still in clinical trials, mainly focusing on their characteristics, adverse effects and combination regimens.
