RESUMEN
Objective:To explore the effect of pre-hospital health education based on "Internet +" on self-management efficacy, anxiety and depression of patients undergoing pulmonary tumor surgery, and provide reference for pre-hospital nursing care of this group.Methods:It was a randomized controlled trial. A total of 100 outpatients in Department of Pulmonary Oncology, Tumor Hospital of Tianjin Medical University to be hospitalized for surgery during November 2021 to March 2022, were divided into experimental group ( n=50) and control group ( n=50) by random number method according to the order of outpatient visits. Patients in control group received routine thoracic surgery nursing and health education after admission. Those in experimental group received "Internet +" pre-hospital health education during patients waiting for hospital beds for surgery, nursing care after admission was the same as that of the control group. The scores of Strategies Used by People to Promote Health (SUPPH) and Hospital Anxiety and Depression Score (HADS) were compared between the two groups 1 day before discharge. Results:At the time of outpatient visit, there was no statistically significant difference between the two groups in the comparison of all dimensions and total scores of SUPPH and the score of HADS ( P>0.05). Total SUPPH score, and self-decompression, self-decision and positive attitude score of experimental group were (110.62 ± 17.73) points, (38.74 ± 6.56) points, (11.98 ± 2.20) points, (59.90 ± 10.18) points, respectively, while in the control group, the scores were (92.86 ± 18.91) points, (32.46 ± 7.39) points, (9.76 ± 2.00) points and (50.64 ± 11.50) points, respectively, with statistically significant differences ( t values were -5.29--4.27, all P<0.01). Besides, the anxiety and depression scores of HADS in experimental group were (3.92 ± 2.25) points and (3.36 ± 2.38) points, respectively, while those in control group were (7.12 ± 3.49) points and (7.00 ± 3.53) points, respectively, and the differences were statistically significant ( t=5.45, 6.04, both P<0.01). Conclusions:The "Internet +" pre-hospital health education model can promote the self-management efficacy of patients undergoing pulmonary tumor surgery, and improve their psychological state during treatment. The study provided reference for promoting diversified extended nursing services in clinical practice.

Objective To study the impact of hepatitis B virus (HBV) infection on the activity of cord hematopoietic stem cells. Methods CD34+ cells were isolated from healthy human cord blood by miniMACS. Cells were cultured in IMDM complete culture medium containing stem cell factor (SCF),fms-like tyrosine kinase 3 ligand (FL), thrombopoietin (TPO), interleukin-3 (IL-3) and 10% fetal bovine serum. High copies HBV were added to the culture system. The proliferation of stem ceils and virus replication were observed. Following the proliferation, dendritic cells (DCs) were induced by adding granulocyte-macrophage colony-stimulating factor and IL-4. Morphous of stem cells and DCs were observed by microscope and the cell surface molecules were detected. Results The proliferation of stem cells infected with HBV was significantly lower than that of healthy stem cells (P＜0.01),and enhanced after adding cytokines (P＜0.01). At the same time, HBV replication was increased after adding cytokines in the culture system (P＜0.01), but the proliferation was still lower than that of healthy stem cells with cytokines in the culture medium (P＜0.05). Dane particles were found in the cytoplasma of stem cells infected with HBV by electron microscope. The expression of CD80,CD86 ,CD1a and HLA-DR on DCs derived from HBV infected stem cells were all lower than those on DCs from non-infected stem cells (P＜0.01). Conclusions HBV could infect CD34+ stem cell and the proliferation of the stem cell could enhance the virus replication. HBV could not only inhibit the proliferation of stem cells,but also down-regulate the immuno-phenotype expression of DCs derived from CD34+stem cells.
RESUMEN
Objective: To determine the contents of paeoniflorin and glycyrrhizic acid in Gianggan Capsules by RP HPLC. Methods: The Chromatographic method was carried out on Kromasil C 18 column using acetonitrile phosphate buffer solution (pH=5) (20∶80) as a mobile phase. The detection wavelength was set at 230nm and 250nm. The flow rate was 1ml/min. The column temperature was 40℃. Results: The paeoniflorin and glycyrrhizic acid calibration curves were linear at the ranges of 0.48～4.80?g and 1.08～10.81?g(r=0.9999). The average recoveries were 100.5% with RSD 1.2% for paeoniflorin and 98.9% with RSD 0.9% for glycyrrhizic acid. Conclusion: This method is simple, reliable and provides a reference standard for the quality control of Gianggan Capsules.
