Objective To apply the feedback closed-loop management systemin the telephone follow-up service for discharged patients to increase patient satisfaction and improve the quality of nursing. Methods From January 2015,telephone return visit to discharged patients were analyzed, a summary of dissatisfaction events, analyze the causes every month. Then,the improvement measures for nursing quality were put forward and the effects were evaluated to form a closed-loop management system. Results After the application of feedback closed-loop management system,there was a significant difference in patients' satisfaction with nursing service between the first half (with the incidence of 91.77%,3657/3985) and the second half (with the incidence of 95.76%,3610/3770) of 2015 (χ2=52.22, P < 0.01). Of the 9 items of dissatisfaction recorded in the questionnaire, significant difference was observed in 8 items, as service attitude, hospitalizing education, personal care, question answering, nurse's operation, health education, respect, clean environment and the discharge instructions. The incidence of each item was 2.11%(84/3985), 0.23%(9/3985), 0.35%(14/3985), 0.33%(13/3985), 0.30%(12/3985), 2.99%(119/3985), 0.33%(13/3985), 0.58%(23/3985), 2.58%(103/3985) in the first half of 2015 respectively, compared to 1.09%(41/3770), 0.05%(2/3770), 0.05%(2/3770), 0.08%(3/3770), 0.21%(8/3770), 0.64%(24/3770), 0.85%(32/3770), 0.21%(8/3770), 1.25%(47/3770) in the second half of 2015 respectively (χ2=4.084-59.088,P<0.01 or 0.05). However, no significant difference was observed in the nurse operational between the first half (0.30%) and the second half (0.21%) in 2015 (χ2=0.596, P>0.05). Conclusions Feedback closed-loop management systemic a scientific management theory. It can increase patient satisfaction with nursing service,improve the quality of nursing,and make quality management more scientific and effective .

Pulse-taking is the most specific diagnostic method of TCM.Its significance has been recognized by ancient and modern doctors.However,at present the application and spread of pulse-taking is limited.In this paper,the author made detailed explorations of literatures and studies the value of pulse condition in guiding syndrome differentiation of liver diseases.The study shows abnormal pulse in left guan and taut pulse in cunkou location both suggest the liver is disordered.We can judge the location of diseases through pulse condition.This exploration shows pulse-taking plays important role in syndrome differentiation.But there is one thing should be paid more attention,pulse condition should be integrated with other symptoms,that will be reliable in guiding diagnosis.

Traditional sample entropy fails to quantify inherent long-range dependencies among real data. Multiscale sample entropy (MSE) can detect intrinsic correlations in data, but it is usually used in univariate data. To generalize this method for multichannel data, we introduced multivariate multiscale entropy into multiscale signals as a reflection of the nonlinear dynamic correlation. But traditional multivariate multiscale entropy has a large quantity of computation and costs a large period of time and space for more channel system, so that it can not reflect the correlation between variables timely and accurately. In this paper, therefore, an improved multivariate multiscale entropy embeds on all variables at the same time, instead of embedding on a single variable as in the traditional methods, to solve the memory overflow while the number of channels rise, and it is more suitable for the actual multivariate signal analysis. The method was tested in simulation data and Bonn epilepsy dataset. The simulation results showed that the proposed method had a good performance to distinguish correlation data. Bonn epilepsy dataset experiment also showed that the method had a better classification accuracy among the five data set, especially with an accuracy of 100% for data collection of Z and S.

BACKGROUND:Extraction methods of human amniotic mesenchymal stem cells are inconsistent in the number of cells.
OBJECTIVE:To explore the optimal method to in vitro isolate and culture human amniotic mesenchymal stem cells.
METHODS:Under sterile conditions, ful-term cesarean fetal amniotic membrane was cut into pieces, then to isolate human amniotic mesenchymal stem cells by seven methods in four experiments. In experiment 1, human amniotic mesenchymal stem cells were isolated by the fol owing three methods:(1) 0.05 g/L trypsin digestion for 10 minutes fol owed by 0.75 g/L col agenase digestion for 60 minutes;(2) 0.75 g/L col agenase I for 120 minutes;(3) co-digestion with 0.05 g/L trypsin and 0.75 g/L col agenase for 60 minutes. In experiment 2, the samples were digested with 0.05 g/L trypsin digestion for 30 minutes fol owed by 0.75 g/L col agenase digestion for 30 minutes. In experiment 3, the samples were digested by two methods:(1) 0.05 g/L trypsin digestion for 30 minutes×2, fol owed by 0.75 g/L col agenase digestion for 60 minutes;(2) 0.05 g/L trypsin digestion for 40 minutes×2, fol owed by 0.75 g/L col agenase digestion for 60 minutes. In experiment 4, the samples were digested with 0.05 g/L trypsin digestion for 30 minutes×2, fol owed by 1 g/L col agenase digestion for 60 minutes. Fol owing morphology observation under a microscope, we studied the most suitable method for isolating human amniotic mesenchymal stem cells.
RESULTS AND CONCLUSION:Digestion with 0.05 g/L trypsin for 30 minutes twice fol owed by 1 g/L of col agenase digestion of 60 minutes was the most suitable isolation and culture condition in vitro. cells became elongated fusiform or star-shaped with rich cytoplasm, and nuclei were round with 1-3 nuts. We can harvest the most number of human amniotic mesenchymal stem cells using the method described in experiment 4.

Objective To observe the value of one-step spectral imaging and perfusion imaging in diagnosis of solitary pulmonary nodule(SPN).Methods Forty-seven patients with SPN proved by pathology underwent perfusion scan with gemstone spectral ima-ging mode,who were divided into malignant group in 28 patients and benign one in 1 9.The parameters of CT perfusion including blood volume (BV),blood flow (BF),mean transit time (MTT)and permeability surface (PS)were analyzed.Iodine concentration (IC),normalized iodine concentration (NIC)and slope rate of spectral curve in both arterial phase and venous phase were measured and calculated.The independent sample t test was performed to compare quantitative parameters between malignant and benign SPN.Results BF,BV and PS of malignant SPN were higher than those of benign ones (P <0.05).No statistically significantly differences between malignant and benign SPN were found (P >0.05).IC,NIC and slope rate of spectral curve in malignant SPN were higher than those in benign ones in both phases (P <0.05).Conclusion One-step spectral imaging and perfusion imaging can provide more parameters,which is helpful for the diagnosis of SPN.

Objective To investigate the feasibility of using recombinant infectious clones of hu-man coronavirus OC43 (HCoV-OC43) as a vector for the expression of exogenous genes and to analyze the insertion sites. Methods Based upon pBAC-OC43FL, a full-length cDNA infectious clone of HCoV-OC43, three recombinant expression plasmids ( pBAC-OC43-GFPΔNS2, pBAC-OC43-GFPΔNS12. 9 and pBAC-OC43-N-GFP) were respectively constructed by replacing NS2 and NS12. 9 genes with the reporter gene en-coding the green fluorescent protein ( GFP ) and inserting the reporter gene after the N gene by using the overlapping-PCR and in vitro ligation. Reverse genetics techniques were used for viral rescue. All of the res-cued virus strains were characterized by immunofluorescence assay ( IFA) and Western blot ( WB) assay af-ter transfecting BHK-21 cells with the recombinant viruses. Results Two recombinant viruses, OC43-GFPΔNS2 and OC43-GFPΔNS12. 9, could be successfully rescued by transfection the BHK-21 cells with pBAC-OC43-GFPΔNS2 and pBAC-OC43-GFPΔNS12. 9 plasmids. The expressed GFP was observed in BHK-21 cells transfected with pBAC-OC43-GFPΔNS2 or pBAC-OC43-GFPΔNS12. 9 plasmids, but not in the cells transfected with the pBAC-OC43-N-GFP plasmid. An efficient and stable expression of GFP was observed in the pBAC-OC43-GFPΔNS2 plasmid-transfected cells. The 10th generation of OC43-GFPΔNS2 virus was ob-tained after repeated freezing and thawing. The expression of GFP and N protein were detected in cells infec-ted with the OC43-GFPΔNS2 virus after 10 passages. Conclusion The NS2 gene of HCoV-OC43 could be used as a promising insertion site of the pBAC-OC43 FL infectious clone for the expression of exogenous genes. This study might provide a platform for further researches on the replication of HCoV-OC43 and the development of human coronavirus-based vectors.
