To observe the effect of livin gene-specific siRNA interference on proliferation and apoptosis of nasopharyngeal carcinoma (NPC) cell line CNE-2Z.Methods: siRNA expression vectors pGPU6/GFP/Neo-livin were transfected into NPC cell line CNE-2Z by using Lipofectamine 2000.The expressions of livin mRNA and protein were detected by semi-quantitative reverse transcriptase-polymerase chain reaction ( RT-PCR) and Western blot.The changes of caspase-3 activity were assessed by kinase semi-quantitative activity test.The proliferation activity and apoptosis of CNE-2Z cells were examined by MTT and flow cytometry respectively.Results:The expression levels of livin mRNA and protein in pGPU 6/GPF/Neo-livin transfected CNE-2Z cells were significantly lower than those in untreated and pGPU 6/GFP/Neo-shNC ( control non-target siRNA ) transfected cells with the expression inhibitory rate of 64.38% and 61.43% respectively.The caspase-3 activity and the apoptotic rate of experimental group cells were increased obviously.The growth of CNE-2Z cells was inhibited by siRNA recombinant expression vector transfection.Conclusion:siRNA targeting livin gene inhibits proliferation and induce apoptosis of CNE-2Z cells.

Objective To investigate the clinical value of sB7-H3 in predicting the severity of acute pancreatitis at early stage. Methods By using the double antibody sandwich ELISA method, the level of plasma sB7-H3 was measured at 24h after onset of abdominal pain in 75 patients with acute pancreatitis (MAP30, MSAP20, SAP25), and 20 healthy persons were enrolled in the controlgroup.The sensitivity and specificity correlations of sB7-H3 in acute pancreatitis with severity degree , as well as with the clinical detection index , were also evaluated. Results The level of plasma sB7-H3 at 24 h in the AP group was significantly higher than that in the healthy control ( HC) group (t = 3.925, P = 0.0002), however, no significant difference was found between the MAP groep and the HC group (P>0.05). The levels of plasma sB7-H3 in the MSAP and the SAP group were significantly higher than that in the HC group (P<0.05和P<0.001)or the MAP group (P<0.05 和P<0.01);The level of plasma sB7-H3 in the SAP group was also markedly higher than that in the MSAP group (P < 0.01). sB7-H3 had a linear positive correlation with LDH、hs-CRP、WBC(P<0.05). ALB had a linear negative correlation with and Ca (S)(P<0.05). By the cutoff of sB7-H3, the sensitivity and specificity to judgethe above moderate pancreatitis were 88.9%and 83.3%,and to judgethe SAP were 96%and 96%. Conclusion sB7-H3 has important clinical value to judge the severity of acute pancreatitis at early time with high sensitivity and specificity , with a linear correlation with the clinical severity index.

Objective:To investigate the effects of Helicobacter pylori on NLRP3 inflammasomes activation in THP-1 ( human monocytic cell line) -derived macrophages and evaluate the role of ROS.Methods:H.pylori strain SS1 was co-cultured with the THP-1-derived macrophages at a multiplicity of infection (MOI) of 1∶100 based on trial results with different MOIs (ratios of THP-1 cells to bacteria ranging from 1∶25 to 1∶200).The co-culture supernatants and THP-1 cells were collected at various time points (3 h,6 h,12 h,24 h) and cytokine production was quantitated using ELISA analysis.The generation of intracellular ROS was detected by FCM,and the mRNA transcript levels of NLRP3 and caspase-1 were measured by Real-time PCR.Western blot was employed to analyze the expression of active caspase-1 subunit ( p10).Then we observed the inhibitory effects of NAC and siRNA specific for NLRP3 on the ex-pression of NLRP3 inflammasome-related components and the secretion of cytokines induced by H.pylori.Results:We found that H.pylori SS1 induced IL-1βand IL-18 production in human acute monocytic leukemia cell line THP-1 in a time-and dose-dependent manner.We further showed that H.pylori could induce the mRNA expressions of NLRP3 and caspase-1 in THP-1 cells.Moreover, release of IL-1βand IL-18 from H.pylori-infected THP-1 cells was suppressed by the ROS scavenger NAC,which was an agent known to inhibit NLRP3 inflammasome formation.NAC administration also resulted in a significant decrease in the level of H.pylori-induced caspase-1 protein expression in THP-1 cells.Additionally,secretion of IL-1βand IL-18 in response to H.pylori infection was remarkably reduced by NLRP3-siRNA.Conclusion:The induction of IL-1βand IL-18 secretion by H.pylori strain SS1 in THP-1 cells could be mediated through activation of NLRP3 inflammasome via ROS signaling pathway, which may be involved in the host innate immune defence and the pathogenesis of the bacteria.

Objective To identify the peptide that have strong ability binding to HCMV-UL149 encoded protein,and to analyze the characteristics of the amino acid sequence of UL149-binding peptides.Methods Expressed UL149 proteins of three genotypes were used to screen the binding peptide in the random peptide display library,then the encoding sequence of binding peptides in the selected clones were sequenced.The amino acid sequences of the binding peptides were analyzed for their homology,and were com pared with those of the known protein in protein banks.Results The homologous amino acid sequence W/A/F/V-D/E-D/E-G-W/F/I/L were found within the binding peptides selected by proteins of all the three UL149 genotypes proteins,and no difference between three groups was found.The alignment with amino acid sequences of the known proteins in protein banks showed that the binding peptides of UL149 putative protein have homologous amino acid sequences with immunoglobulin heavy chain variable region(IgHV),the serine/threonine protein kinases,compliment factor H,zinc finger protein,MHC Ⅰ molecule,eukaryotic translation initiation factor,nuclear factor and so on.Conclusion The UL149 encoding proteins have binding ability to proteins mentioned above,and might interfere with the immunity responds to HCMV infection through multiple mechanisms.

Crn concentration in blood(mg/dl)?28.754-0.631.Conclusion Using a linear regression formula to predict the muscular Glx concentration,the results can reflect the level of the true values without biopsy,though it's not accurate enough for quantitatively analysis.

Objective To explore the theory of curriculum contents for gerontological nurse practitioner training which is suitable for the situation of our country. Method Delphi technique was used in this research to build content indicators of gerontological nurse practitioner training curricu-lum, and calculate the variation coefficient. Results The theory training curriculum includes founda-tions of gerontological nursing, geriatric syndrome, facilitating physiological balance and general gero-tological care modules and 41 core indexs. Every coefficient of variation is less than 20 percent [(4.35±0.71), (4.63±0.57), (4.55±0.57), (4.67±0.55)]. The mean values of the importance (4.54± 0.622) and general characteristics are more than four. Conclusion The content setting of the geron-tological nurse practitioner training theory course not only highlights the training characteristics of the geriatric care, but also has comprehensive and systematic content, reflects humanistic care spirit and pays attention to developing nurses’clinical practice ability. Therefore, it is worthy of reference and promotion.

OBJECTIVETo evaluate the clinical efficacy of syndrome differentiation-based treatment with traditional Chinese medicine (TCM) versus losartan therapy in addition to basic treatment for management of proteinuria in patients with chronic kidney disease.

METHODSThis multicenter, randomized, and case-controlled clinical trial was conducted among 81 consecutive patients meeting the inclusion criteria. The patients were randomized consecutively to receive TCM treatments according to the syndrome patterns in TCM (spleen and kidney Qi and Yin deficiency, and spleen and kidney Qi and Yang deficiency, n=60) or oral losartan therapy (50 mg/day, n=21) in addition to the basic treatments. All the patients were followed up for 24 weeks to observe the clinical effects.

RESULTSThe patients in TCM group showed a significantly higher overall response rate (93.33%) than those in losartan group (76.20%, P<0.05). The TCM score in the two groups were all decreased at week 24 as compared with baseline (P<0.01 or P<0.05). The TCM scores in both groups decreased significantly after the treatments as compared with the baseline scores (P<0.05). After a 8-week-long treatment, Scr, eGFR and Cys-C, U-Pro/24 h, and MA/Cr all decreased significantly in TCM group (P<0.05) but showed no significant changes in losartan group (P>0.05).

CONCLUSIONSyndrome differentiation-based TCM treatment in addition to basic treatments can produce satisfactory therapeutic effects on proteinuria in patients with chronic kidney disease by improving the clinical symptoms, reducing TCM symptom scores and proteinuria, and protecting the renal functions.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.
