Cardiac enlargement is an important symptom of vascular and heart disease. The cardiothoracic ratio (CTR) is an important index used to measure the size of heart. The aim of this study was to assess the relationship between aging and cardiothoracic ratio. This paper also presents an improved C-V level set method to segment lung tissue based on X-ray image, which used to automatically compute CTR. In the investigation carried out in our school, we got more than 3 120 chest radiographs from medical examination of the working population in Beijing, and we systematically studied the effects of age and gender on the CTR to obtain reference values for each group. The reference values established in this study can be useful for recording and quantifying the cardiac enlargement, so that it may be useful for calling attention to the cardiovascular diseases and the heart diseases.

AIM: To study the effect of CPUE1 on the reversal of multidrug resistance (MDR) in K562/A02 cells and its mechanism. METHODS: MTT assay was used to determine the influence of CPUE1 on the cytotoxicity of vincrisine (VCR) in K562/A02 cells. The effect of CPUE1 on the apoptosis induced by VCR in K562/A02 cells was detected using DNA analysis and Annexin-Ⅴ/PI double stain assay. Flow cytometry was used to investigate the efflux of rhodamine123 (Rh123) by P-glycoprotein (P-gp) in K562/A02 cells. RESULTS: CPUE1 increased the cytotoxicity and apoptosis induced by VCR in K562/A02 cells. At the concentration of 10 ?mol?L -1 ,CPUE1 reduced the IC_ 50 value of VCR from 60.54 to 4.17 ?mol?L -1 . CPUE1 inhibited the efflux of Rh123 and resulted in the increase of intracellular accumulation of Rh123 in K562/A02 cells. CONCLUSION: CPUE1 has strong reversal effect on MDR in K562/A02 cells by inhibiting P-gp activity.

Objective To evaluate the neuroprotective effects of glycyrrhizin (GL) on vascular dementia (VaD) in vivo and Glutamate-induced damage in vitro. Methods Male Wistar rats were subjected to permanent occlusion of the bilateral common carotid arteries. On d 15 postsurgery, rat cognition was assessed using the Morris water maze. The activity of superoxide dismutase and the content of malondialdehyde of brains were also measured. Brain damage was evaluated histologically using HE staining. In vitro cell viability was examined in PC12 cells exposed to Glutamate,and mRNA levels of Bc1-2 and Bax were assessed. Results GL (20 mg/kg for 12 d) improved the performance of learning and memory of VaD rats, decreased the level of lipid peroxidation, and attenuated the pathological alrations in the hippocampal CA1 and CA3 areas. Moreover, GL (0.6 mmol/L) could protect PC12 cell lines from injury induced by Glutamate (10 mmol/L) and inhibit apoptosis of neuronal cells. Conclusion The present findings suggest that GL may have therapeutic potential in treating VaD.

Aim To study the reversal effect of CPUC1 on multidrug resistance in K562/A02 cells. Methods MTT assay was used to detect the cytotoxicity of vincristine. Intracellular accumulation of rhodamine123 was measured by flow cytometry to evaluate the function of P glycoprotein(Pgp). The apoptotic cells induced by vincristine were detected by flow cytometry using DNA content analysis and Annexin V/PI double staining. Results CPUC1 significantly reversed the resistance of K562/A02 cells to vincristine. CPUC1 increased intracellular accumulation of rhodamine123 in K562/A02 cells in a concentration dependent manner. CPUC1 increased the apoptosis induced by vincristine. Conclusion CPUC1 reversed multidrug resistance by inhibiting function of P gp in K562/A02 cells, suggesting that CPUC1 merits further study.

Objective To investigate the expression change of renal NLR family pyrin domain containing-3 protein(NALP3) in-flammasome in the nephrotic syndrome(NS) patients with focal segmental glomerulosclerosis(FSGS) and its relation with the tubu-lointerstitial pathogenic injury degree ,expression of inflammatory factors and clinical biochemical indexes .Methods Immunohisto-chemistry was used to detect the expressions of NALP3/ASC/caspase-1 and their downstream effector molecule IL-1β,IL-18 in re-nal tubular epithelial cells .The tubulointerstitial injury score and the activated macrophages F4/80 in renal interstitium of the FSGS patients and NS patiens were evaluated .The serum creatinine ,urea ,total protein ,albumin ,24 h urine protein and estimated glomer-ular filtration rate(eGFR) were observed .The correlation of tubulointerstitial injury with NALP3/ASC/caspase-1 ,IL-1β,IL-18 were respectively analyzed .Results The expression of NALP3/ASC/caspase-1 ,IL-1β,IL-18 in the renal tissue of the FSGS pa-tients was significantly increased compared with that in the control group (P<0 .01) .NALP3/ASC/capspase-1 expression was pos-itively correlated with the expression of IL-1β,IL-18(P< 0 .01) .NALP3/ASC/caspase-1 ,IL-1β,IL-18 expression was positively correlated with renal tubulointerstitial injury and the F4/80 expression intensity(P<0 .01) .NALP3/ASC/caspase-1 ,IL-1β,IL-18 was significantly positively correlated with 24 h urine protein and Scr ,and negatively correlated with the eGFR (P<0 .05) ,but had no obvious correlation with plasma urea ,plasma total protein and albumin concentrations .Conclusion The NALP3 inflammasome might participate in the pathogenic mechanism of FSGS through the activation of its downstream inflammatory factor of IL-1β,IL-18 ,the more higher its expression degree ,the more severe the renal tissue injury ,whether which could be served as the warning in-dex needs the further clinical verification .

Objective To compare the eficacy and safety of flexible laryngeal mask (FLMA) and endotracheal tube (ETT) in children undergoing adenoidectomy and tonsillectomy. Methods Forty children with snoring disease scheduled for selective adenoidectomy and tonsillectomy surgery under intravenous compound inhalation general an-esthesia were divided randomly into either FLMA group or ETT group. MAP,HR and SpO2 were recorded before an-esthesia induction(T0 ), 1 (T1 ),3 (T2 ),5 (T3 ) min after intubation,1(T4 ),3 (T5 ) min after extubation. Param-eters for respiratory mechanics included peak airway pressure (Ppeak ), mean airway pressure (Pmean ), end tidal CO2 (PetCO2 ),and airway sealing pressure. All of the above indicators were recorded 5 min (T6 ) after intubation, 10 (T7 ),20 (T8 ) min after put in mouth gag,5 (T9 ) min after removing mouth gag. Meanwhile,chievement ratio of first time insertion,incidence of regurgitation aspiration,bucking,laryngospasm,wheezing when extubation and af-ter extubation,anesthesia time,surgery time,extubation time were recorded. Complications such as nausea and vomi-ting,pharyngeal pain,hoarseness were followed up 24 hours after surgery. Results MAP, HR during T1 , T2 , T3 , T4 ,T5 were significantly higher in group T than T0 , and those in group FLMA (P<0.05). MAP, HR were not sig-nificantly changed in group FLMA during each time. Ppeak , Pmean was significantly lower in group FLMA than that in group ETT. The extubation time was shorter and the incidence of coughing and pharyngalgia after operation was low-er in group FLMA than that in group ETT. Conclusion Compared with endotracheal intubation, on the basis of not affecting surgical operation, FLMA is an effective, safe anesthesia for adenoidectomy and tonsillectomy surgery in children, with the advantages of hemodynamic stability, mild airway trauma,and is a easy handling method, with minor laryngeal stimulation during intubation and extubation, more stable hemodynamics, reliable respiratory me-chanics and low incidence of postoperative upper airway complications.

Allogeneic hematopoietic stem cell transplantation and donor lymphocyte infusion for multiple myeloma (MM) can induce graft-versus-myeloma immunity and long-term survival,but limited efficacy and associated toxicities have prevented its widespread application.Cellular immunotherapies and vaccines are explored to induce more specific,reliable,and potent antimyeloma immune responses with less treatmentrelated risk.Advances in molecular biology,basic and applied immunology,have led to several promising approaches such as genetically engineered T cells with chimeric antigen receptors and T-cell receptors targeting myeloma-specific epitopes,vaccine primed ex vivo expanded autologous T cells,expanded marrowinfiltrating lymphocytes,and plasma cell/dendritic cell fusion vaccines.The combination of these emerging therapies to immunomodulatory drugs and inhibitors of programmed death-1 T-cell regulatory pathways could improve the outcome for MM patients.This article reviews the latest progress of cellular and vaccine immunotherapy for MM at the 58th American Society of Hematology (ASH) Annual Meeting,and discusses how these therapies might integrate and synergize with existing treatment paradigms.
