RESUMEN
AIM: To investigate the effects of curcumin on the proliferation and apoptosis and migration of human pterygium fibroblasts(HPF)in vitro.METHODS: A total of 7 cases of pterygium tissue removed at our hospital from November 24, 2021 to December 16, 2021 were collected. Then, primary fibroblasts were cultured in vitro and identified by immunofluorescence staining. HPF were treated with 0, 10, 20, 40, 80 and 160μmol/L curcumin containing equal amount of dimethyl sulfoxide for 24h, then the cell proliferation was detected by CCK8 assay. According to the results of CCK8, the cells were divided into control group, 20μmol/L curcumin group and 40μmol/L curcumin group, and the cells were treated with corresponding concentration of curcumin for 24h in each group. Flow cytometry was used to detect apoptosis, Transwell migration assay was used to detect cell migration, and real-time fluorescence quantitative polymerase chain reaction and Western blot were used to detect the expression of mRNA and protein of B-cell lymphoma-2 associated X protein(Bax), B-cell lymphoma-2(Bcl-2), Cyclin D1 and matrix metalloproteinase 2(MMP2).RESULTS: Compared with the control group, both 20μmol/L curcumin group and 40μmol/L curcumin group can inhibit the proliferation and migration of HPF and induce its apoptosis(all P<0.05). Compared with the control group, 20μmol/L curcumin group can down-regulate the mRNA expression of Cyclin D1 and MMP2, up-regulate the mRNA expression of Bax, and down-regulate the protein expression of Bcl-2(all P<0.05). Compared with the control group, 40μmol/L curcumin group can down-regulate the expression of mRNA and protein of Bcl-2, Cyclin D1 and MMP2, and up-regulate the expression of mRNA and protein of Bax(all P<0.05). Compared with 20 μmol/L curcumin group, the 40 μmol/L curcumin group can down-regulate the mRNA expression of MMP2, down-regulate the protein expression of Bcl-2, and up-regulate the mRNA and protein expression of Bax(all P<0.05).CONCLUSION: Curcumin can inhibit the proliferation of HPF by inhibiting the expression of Cyclin D1, induce the apoptosis of HPF by down-regulating Bcl-2 and up-regulating the expression of Bax, and inhibit the migration of HPF by down-regulating the expression of MMP2.
RESUMEN
Objective: To compare the prognosis of mildly or severely symptomatic patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent alcohol septal ablation (ASA). Methods: This retrospective study cohort consisted of patients with OHCM who received ASA treatment in Beijing Anzhen Hospital, Capital Medical University from March 2001 to August 2021. These patients were divided into mildly and severely symptomatic groups according to the severity of clinical symptoms. Long-term follow-up was conducted, and the following data were collected: duration of follow-up, postoperatire treatment, New York Heart Association (NYHA) classification, arrhythmia events and pacemaker implantation, echocardiographic parameters, and cause of death. Overall survival and survival free from OHCM-related death were observed, and the improvement of clinical symptoms and resting left ventricular outflow tract gradient (LVOTG) and the incidence of new-onset atrial fibrillation were evaluated. The Kaplan-Meier method and log-rank test were used to determine and compare the cumulative survival rates of the different groups. Cox regression analysis models were used to determine predictors of clinical events. Results: A total of 189 OHCM patients were included in this study, including 68 in the mildly symptomatic group and 121 in the severely symptomatic group. The median follow-up of the study was 6.0 (2.7, 10.6) years. There was no statistical difference in overall survival between the mildly symptomatic group (5-year and 10-year overall survival were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year overall survival were 94.2% and 83.9%, respectively, P=0.405); there was also no statistical difference in survival free from OHCM-related death between the mildly symptomatic group (5-year and 10-year survival free from HCM-related death were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year survival free from HCM-related death were 95.2% and 92.6%, respectively, P=0.846). In the mildly symptomatic group, NYHA classification was improved after ASA (P<0.001), among which 37 patients (54.4%) were in NYHA class Ⅰ, and the resting left ventricular outflow tract gradient (LVOTG) decreased from 67.6 (42.7, 90.1) mmHg (1 mmHg=0.133 kPa) to 24.4 (11.7, 35.6) mmHg (P<0.001). In severely symptomatic group, NYHA classification was also improved post ASA (P<0.001), among which 96 patients (79.3%) improved by at least one NYHA classification, and the resting LVOTG decreased from 69.6 (38.4, 96.1) mmHg to 19.0 (10.6, 39.8) mmHg (P<0.001). The incidence of new-onset atrial fibrillation was similar between the mildly and severely symptomatic groups (10.2% vs. 13.3%, P=0.565). Cox multivariate regression analysis showed that age was an independent predictor of all-cause mortality in OHCM patients post ASA (HR=1.068, 95%CI 1.002-1.139, P=0.042). Conclusions: Among patients with OHCM treated with ASA, overall survival and survival free from HCM-related death were similar between mildly symptomatic group and severely symptomatic group. ASA therapy can effectively relieve resting LVOTG and improve clinical symptoms in mildly or severely symptomatic patients with OHCM. Age was an independent predictor of all-cause mortality in OHCM patients post ASA.

OBJECTIVE@#This study aimed to reveal the insomnia burden and relevant influencing factors among informal caregivers (ICs) of hospitalized patients with lung cancer.@*METHODS@#A cross-sectional study on ICs of hospitalized patients with lung cancer was conducted from December 31, 2020 to December 31, 2021. ICs' burden was assessed using the Caregiver Reaction Assessment (CRA), Hospital Anxiety and Depression Scale (HADS), and Insomnia Severity Index (ISI). Linear and logistic regression models were used to identify the influencing factors.@*RESULTS@#Among 289 ICs of hospitalized patients with lung cancer, 83 (28.72%), 53 (18.34%), and 14 (4.84%) ICs experienced mild, moderate, and severe insomnia, respectively. The scores concerning self-esteem, lack of family support, financial problems, disturbed schedule, and health problems were 4.32 ± 0.53, 2.24 ± 0.79, 2.84 ± 1.14, 3.63 ± 0.77, and 2.44 ± 0.95, respectively. ICs with higher Activities of Daily Living Scale (ADLS) scores were associated with a lower risk of insomnia, with an odd ratio ( OR) and 95% confidence interval ( CI) of 0.940 (0.898-0.983). Among the ICs, female gender ( OR = 2.597), alcohol consumption ( OR = 3.745), underlying medical conditions ( OR = 11.765), long-term caregiving experience ( OR = 37.037), and higher monthly expenses ( OR = 5.714) were associated with a high risk of insomnia.@*CONCLUSION@#Of the hospitalized patients with lung cancer, 51.9% experienced insomnia. Patients' ADL, ICs gender, alcohol consumption, underlying medical conditions, caregiving duration, and monthly expenses were influencing factors. Therefore, prompt screening and early intervention for ICs of patients with lung cancer is necessary.

Objective: To investigate the characteristics, risk factors and outcomes of thalassemia major (TM) children with pericardial effusion (PE) after allo-geneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Clinical data of 446 TM children received allo-HSCT at Shenzhen Children's Hospital between January 2012 and December 2020 were analyzed retrospectively. Patients were divided into PE and non-PE group according to the occurrence of PE. Chi-square tests were used to investigate the risk factors that were associated with the development of PE. Kaplan-Meier method was used for survival analysis of the 2 groups. Results: Twenty-five out of 446 patients (5.6%) developed PE at a time of 75.0 (66.5, 112.5) days after allo-HSCT. Among these patients, 22 cases (88.0%) had PE within 6 months after allo-HSCT and 19 patients (76.0%) had PE within 100 days after allo-HSCT. The diagnoses of PE were confirmed using echocardiography. Pericardial tamponade was observed in only 1 patient, who later undergone emergency pericardiocentesis. The rest of patients received conservative managements alone. PE disappeared in all patients after treatment. Risk factors that were associated with the development of PE after allo-HSCT included the gender of patients, the type of transplantation, the number of mononuclear cells (MNC) infuse, pulmonary infection after HSCT and transplantation associated thrombotic microangiopathy (TA-TMA) (χ²=3.99, 10.20, 14.18, 36.24, 15.03, all P<0.05). In 239 patients that received haploidentical HSCT, the development of PE was associated with the gender of patients, pulmonary infection after HSCT and TA-TMA (χ²=4.48, 20.89, 12.70, all P<0.05). The overall survival rates of PE and non-PE groups were 96.0% (24/25) and 98.6% (415/421). The development of PE was not associated with the overall survival of TM children after allo-HSCT (χ²=1.73, P=0.188). Conclusions: PE mainly develop within 100 days after allo-HSCT in pediatric TM recipients. Haploidentical grafts, female gender, pulmonary infection after HSCT and TA-TMA are the main risk factors associated with PE development after transplant. However, the presence of PE don't have a significant impact on the outcomes of pediatric TM patients after allo-HSCT.

Objective: To observe the therapeutic effects of alcohol septal ablation (ASA) in mildly symptomatic patients (NYHA class Ⅱ) with hypertrophic obstructive cardiomyopathy(HOCM). Methods: This retrospective study included 150 mildly symptomatic patients with HOCM hospitalized in Beijing Anzhen Hospital affiliated to Capital Medical University from March 2001 to December 2017, consisting of medical therapy group (n=102) and ASA group (n=48). Baseline clinical data were collected, patients were followed up to a mean of 6.0 (3.5, 8.1) years. Overall and HCM-related mortality events (including chronic heart failure, atrial fibrillation related stroke, sudden cardiac death) were observed in the two groups. Moreover, the improvement of NYHA function classification and left ventricular outflow tract gradient (LVOTG) were also evaluated. Survival analysis was performed by Kaplan-Meier method. Results: Age of this cohort was (52.9±14.5)years, 92 cases(61.3%) were male. In the follow-up, LVOTG was reduced from (85.8±35.4)mmHg (1 mmHg=0.133 kPa) to (27.7±19.8)mmHg (P<0.001) in the ASA group, and from (66.3±35.0)mmHg to (56.5±27.7)mmHg in medical therapy group(P<0.01). At the last clinical follow-up, there were 32 patients (66.7%) whose LVOTG were<30 mmHg, septal thickness decreased from (20.3±3.8)mm to (16.1±3.4)mm (P<0.001), NYHA classification was also remarkably improved (P<0.001). New-onset atrial fibrillation tended to be lower in the ASA group compared to medical therapy group (9.3%(4/43) vs. 20.8%(20/96),P=0.096). Eleven patients (10.8%) in the medical therapy group and 2 patients (4.2%) in the ASA group died during the follow-up. One patient received pacemaker during the peri-procedural period, 1 patient was implanted with two-chamber pacemaker due to Ⅲ° atrioventricular block at 10 years after operation in the ASA group. Survival free of all-cause mortality of ASA group at 5 and 10 years was 97.9% and 97.9%, respectively, which was comparable to the medical therapy group (P=0.231). Survival free of HCM-related mortality was similar between the two groups (P=0.397). Conclusions: Compared with medical therapy in mildly symptomatic patients with HOCM, long-term survival rate is similar after ASA. Meanwhile, ASA can remarkably reduce LVOTG and improve the clinical status of the patients. Therefore, ASA may be used as an alternative therapy for mildly symptomatic HOCM patients.

Objective: To explore the value of phase angle (PA) in constructing a predictive model of nutrition evaluation for tumor patients. Methods: A retrospective analysis was performed on 1 129 patients with malignant tumors hospitalized in the Cancer Center of Changzhi People's Hospital from June 2020 to February 2021. PA values of six parts of the body were measured by the body composition analyzer, including: left arm (LA), right arm (RA), left leg (LL), right leg (RL), the trunk (TR), and the whole body (WB). Patients' body mass index (BMI) was calculated and patient-generated subjective global assessment (PG-SGA) was assessed. The differences of PA values of six parts were compared and their correlations with BMI and PG-SGA in combination with age, gender and tumor disease types were analyzed, binary classification regression on BMI and PG-SGA was performed, and the functions of the best prediction model was fitted. Decision tree, random forest, Akaike information criterion in a Stepwise Algorithm (stepAIC) and generalized likelihood ratio test were used to select appropriate variables, and the logit logistic regression model was used to fit the data. Results: Comparing the PA values of six parts in pairs, it was found that the PA values of LA and RA, LL and RL, and TR and WB were linearly correlated and the coefficient was close to 1 (P<0.001). Binary classification regression was performed for BMI and PG-SGA, respectively. In order to make the data have clinical significance, 18.5 kg/m(2) was used as the classification point for BMI, 4 and 9 were used as the classification points for PG-SGA score, and the models of A, B and C were obtained. Suitable variables including PA-LA, PA-TR and tumor disease types were used as variables to fit BMI classification; BMI, PA-LA and age were used as variables to fit the PG-SGA model with 9 as the classification point. PA-LA, PA-TR, BMI, age and tumor disease types were used as variables to fit the PG-SGA model with 4 as the classification point. In this study, the predicted values of models A, B and C obtained by R-studio were imported into SPSS 26.0 software, and the cut-off values of classification were obtained by the receiver operating characteristic (ROC) curve. The ROC analytic results showed that the best cut-off values of Model A, B and C were 0.155, 0.793 and 0.295. Model A recommended when the probability is >0.155, a patient's nutritiond tatus should be classified as BMI < 18.5 kg/m(2) group. Model B recommended that PG-SGA<9 group be classified as the probability is >0.793. Model C recommended that PG-SGA < 4 group should be classified when probability is >0.295. Conclusions: The PG-SGA classification prediction model is simple to operate, and the nutritional status of patients can be roughly divided into three groups: normal or suspected malnutrition group (PG-SGA<4), moderate malnutrition group (4≤PG-SGA<9), and severe malnutrition group (PG-SGA≥9). This model can more efficiently predict the nutritional status of cancer patients, greatly simplify the nutritional assessment process, and better guide the standardized treatment of clinical malnutrition.

We examined the attributed fractions of all-cause, cardiovascular, and respiratory mortality that were attributed to extreme and moderate cold and heat during 2010-2016 in Nanjing. Our results showed that 12.81%, 19.78%, and 25.33% of all-cause, cardiovascular, and respiratory mortalities, respectively, were attributed to temperature. The highest attributed fractions for three types of mortality were at 4 ℃ and the attributed fractions were high around 4 ℃, which falls within the moderate cold temperatures. Although moderate cold has lower RR than extreme cold, it occurred on more days than did extreme cold. Therefore, health burden caused by moderate cold requires further attention in the future.

AIM:To investigate the effects of DL-3-n-butylphthalidle (NBP) on angiogenesis of human um-bilical vein endothelial cells ( HUVECs) and the role of vascular endothelial growth factor ( VEGF)/VEGF receptor 2 (VEGFR2)-Notch1/Delta-like ligand 4 (Dll4) signaling pathway in this process. METHODS:The serum-free medium and anoxic tank were used to simulate the conditions of hypoxia and ischemia ( H/I). HUVECs were divided into control group, H/I group, H/I+NBPhigh group and H/I+NBPlow group. The HUVECs in control group were conventionally cul-tured, and those in H/I group were cultured under H/I intervention. The HUVECs in H/I+NBPhigh group were treated with NBP at 20 μmol/L under H/I intervention. The HUVECs in H/I+NBPlow group were treated with NBP at 5 μmol/L under H/I intervention. The cell viability of each group was measured by CCK-8 assay. The migration ability of the HUVECs in each group was detected by cell scratch test. The vessel formation ability of the HUVECs was examined by in vitro angiogenesis assay. The expression of VEGFR2, Notch1 and Dll4 at mRNA and protein levels was determined by qPCR and Western blot, and the expression of VEGF was determined by qPCR and ELISA. RESULTS:NBP increased the viability of HUVECs, and promoted the migration ability and the formation of blood vessels in vitro under H/I interven-tion. These effects of NBP at high dose were more significant than those at low dose. NBP increased the expression of VEGF, VEGFR2, Notch1 and Dll4 at mRNA and protein levels (P<0.05). CONCLUSION:NBP promotes HUVECs to form blood vessels under H/I intervention. The mechanism may be related to the activation of VEGF/VEGFR2-Notch1/Dll4 signaling pathway.
RESUMEN
OBJECTIVE: To evaluate the incidence, characteristics, and variations of the falcine sinus with contrast-enhanced three-dimentional (3D) thin-section magnetic resonance (MR) images. MATERIALS AND METHODS: retrospective review identified 1531 patients (745 males and 786 females, 2 months to 85 years) who underwent cranial MR imaging including T1-weighted imaging, T2-weighted imaging, T2-weighted fluid-attenuated inversion recovery, contrast-enhanced 3D thin-section sagittal scans, and MR venography, from June 2014 to January 2016. The incidence, characteristics of the falcine sinus, and coexisted intracranial lesions were confirmed by two neuroradiologists. RESULTS: Falcine sinuses were identified in 81 (38 males and 43 females) cases (5.3%, 81/1531, 5 months to 76 years of age) with calibers ranging from 2.3 mm to 17.0 mm. Three major forms of falcine sinuses were defined: arch-like (n = 47), stick-like (n = 22), and bifurcated (n = 12). Persistent falcine sinuses were found in 57 cases, among which 3 cases showed complicated cerebral anomalies, and 2 cases showed smaller straight sinuses. Recanalization of falcine sinuses were found in 24 cases, including 17 cases with tumor compression, 6 cases with cerebral venous sinus thrombosis, and one case with hypertrophic meningitis. CONCLUSION: Falcine sinus is not as rare as has been reported previously. Most falcine sinuses are not associated with congenital cerebral abnormalities. Diseases that cause increased pressure in the venous sinus may lead to recanalization of falcine sinus. Illustrating the characteristics of falcine sinus may prompt a more comprehensive understanding and diagnosis of associated diseases, and avoid potential surgical damage in the future.

AIM:To detect the myeloid-derived suppressor cells(MDSCs )in peripheral blood from the pa-tients with Parkinson disease(PD)and its clinical significance.METHODS:The patients(n=80)diagnosed PD from January 2016 to March 2017 in our hospital and 20 healthy volunteers were selected as the subjects.According to the Hoehn-Yahr staging,80 PD patients were staged,of whom 22 were Ⅰ,24 were Ⅱ,20 were Ⅲ,14 were Ⅳ,and 0 was Ⅴ. Peripheral blood(5 mL)samples from the patients with PD and the healthy volunteers were collected and the mononuclear cells were isolated.The levels of CD14 +CD11b+cells and CD14 -CD11b+cells in the peripheral blood were detected by flow cytometry.The two populations of the cells were sorted by magnetic beads.The mRNA levels of arginase 1(ARG1),interleukin-10(IL-10)and cyclooxygenase 2(COX-2)were detected by qPCR.The expression of surface membrane pro-teins CD14 and CD11b,and immunosuppressive factors ARG1,IL-10 and COX-2 was determined by Western blot and ELISA.RESULTS:No significant change of CD14 +CD11b+cells between the patients with PD and normal controls was observed,but the cells with CD14 -CD11b+increased significantly in the patients with PD compared with the control peo-ple(P<0.05).The CD14 -CD11b+cells in peripheral blood of the patients were related to the stage of Hoehn-Yahr.The CD14-CD11b+and CD14+CD11b+cells showed high levels of IL-10 and COX-2,and the high level of ARG1 was only expressed in the CD14 -CD11b+cells.The expression of ARG1 in the CD14 -CD11b+population from PD patients was significantly different from that of CD14+CD11b+population and normal subjects(P<0.05).CONCLUSION:The CD14-CD11b+cells and ARG1 expression level in peripheral blood of the PD patients can be used to evaluate the patho -genesis and staging.Immunosuppression may play an important role in the pathogenesis and development of PD.
RESUMEN
Objectives:The aim of this study was to observe whether transthoracic pulmonary artery denervation (TPADN) could reduce the pulmonary arterial pressure and attenuate pulmonary vascular remodeling in rats with pulmonary arterial hypertension induced by monocrotaline. Methods:Twenty-four healthy male SD rats were randomly divided into control group, sham operation group and operation group (n=8 per group). Rats in sham operation group and operation group received single subcutaneous injection of monocrotaline (MCT, 60 mg/kg). After four weeks, the mean pulmonary arterial pressure (mPAP) and other hemodynamic parameters were measured with the right heart catheter in rats of these two groups. Then, operation group received the surgery of TPADN, which included thoracotomy in left 2-3 rib, exposing pulmonary artery, and removing the near connective tissue of the pulmonary artery trunk. After two weeks of operation, the mPAP and other hemodynamic parameters were measured again by the right heart catheter. The microstructure changes of the heart and pulmonary vessels was observed by immunohistochemistry and immunofluorescence. Meanwhile, RV cardiomyocyte cross-sectional area (CSA) and the right hearthy pertrophy index (RVHI= RV/[LV+S]) were used to evaluate the degree of right ventricular hypertrophy. Results:After four weeks of injection of MCT, the mPAP was significantly higher in the operation group and the sham operation group than in control group (P<0.01). Two weeks after the surgery of TPADN, the mPAP was significantly reduced in the operation group than compared in the sham group(P<0.01). Meanwhile, the percentage of medial thickness to outer diameter of the small pulmonary arterioles, right ventricular myocardial cell cross-sectional area and RVHI were also significantly decreased in the operation group compared to sham operation group(all P<0.01). Conclusions:Our results show that TPADN could reduce the mean pulmonary arterial pressure and attenuate the hypertrophy of medial thickness of small pulmonary arterioles and of right ventricle in PAH rats induced by monocrotaline.

The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.
RESUMEN
To investigate the effect and side effects of Xelox program combined with Xihuang Capsules on therapy to liver metastasis after resection of colon cancer and its impacts on IL-17 and IL-6 levels in serum of patients. Patients with liver metastasis of colorectal cancer after operation (120 cases) were randomly divided into two groups, namely the experimental group and the control group, 60 cases in each group. The patients in the control group were treated with Xerox program, while the patients in the experimental group were treated with the Xelox program and Xihuang Capsules. Twenty healthy cases were controlled. ELISA was used to detect the changes of serum IL-6 and IL-17 of the patients in the experimental group and the control group. Detecting the toxic reaction and hematological tumor makers of the 120 cases after treatment and taking 20 healthy people as control. The effective rates in the experimental group and the control group were 56.67% and 35.59% respectively, which showed the higher in the experimental group than the control group with the significant difference between the two (P < 0.05). The part of toxic reaction and hematological tumor makers in the experimental group were lower than those in the control group, which had significant difference. The levels of IL-17 and IL-6 in serum of the patiente in the experimental group and control group were higher than those in the healthy group (P < 0.05). The levels of IL-17 and IL-6 in the experimental group and control group decreased after the treatment, which the levels of them in the experimental group were more obviously decreased than those in the control group (P < 0.05). Curative efficacy of Xihuang Capsules in adjuvant treatment to colon cancer is reliable, which can reduce chemotherapy part of toxicity and hematological tumor markers, decrease the levels of IL-17 and IL-6, and effectively regulate immune function.
RESUMEN
OBJECTIVE: To develop a method of quantitative analysis of multicomponents by singlemarker (QAMS) for simultaneous determination of six oligosaccharide esters in Polygalae Radix. METHODS: 3, 6'-Disinapoyl sucrose (DISS) was used as the internal reference substance. The relative correlation factors (RCF) of sibiricose A5, sibiricose A6, tenuifoliside B, tenuifoliside A, and tenuifoliside C to DISS were calculated. The contents of the six oligosaccharide esters in 20 different batches of Polygalae Radix were determined by both external standard method and QAMS. The assay results were compared to evaluate the accuracy of QAMS method. RESULTS: The RCF of sibiricose A5, sibiricose A6, tenuifoiside B, tenuifoliside A, and tenuifoiside C to DISS were 1.23, 1.16, 1.56, 1.79, and 0.92, respectively. Under different experimental conditions, the RCF had good reproducibility, and there was no significant difference in the quantitative analysis results between the external standard method and QAMS method. CONCLUSION: The QAMS method is feasible and credible, and can be used for the quality control of oligosaccharide esters in Polygalae Radix.
RESUMEN
<p><b>BACKGROUND</b>The SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery Score II (SS-II) can well predict 4-year mortality in patients with complex coronary artery disease (CAD), and guide decision-making between coronary artery bypass graft surgery and percutaneous coronary intervention (PCI). However, there is lack of data regarding the utility of the SS-II in patients with three-vessel CAD undergoing PCI treated with second-generation drug-eluting stents (DES). The purpose of the present study was to evaluate the ability of the SS-II to predict long-term mortality in patients with three-vessel CAD undergoing PCI with second-generation DES.</p><p><b>METHODS</b>Totally, 573 consecutive patients with de novo three-vessel CAD who underwent PCI with second-generation DES were retrospectively studied. According to the tertiles of the SS-II, the patients were divided into three groups: The lowest SS-II tertile (SS-II ≤20), intermediate SS-II tertile (SS-II of 21-31), and the highest SS-II tertile (SS-II ≥32). The survival curves of the different groups were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relationship between the SS-II and 5-year mortality. The performance of the SS-II with respect to predicting the rate of mortality was studied by calculating the area under the receiver operator characteristic (ROC) curve. The predictive ability of the SS-II for 5-year mortality was evaluated and compared with the SS alone.</p><p><b>RESULTS</b>The overall SS-II was 27.6 ± 9.0. Among patients in the lowest, intermediate and the highest SS-II tertiles, the 5-year rates of mortality were 1.6%, 3.2%, and 8.6%, respectively (P = 0.003); the cardiac mortality rates were 0.5%, 1.9%, and 5.2%, respectively (P = 0.014). By multivariable analysis, adjusting for the potential confounders, the SS-II was an independent predictor of 5-year mortality (hazard ratio: 2.45, 95% confidence interval: 1.38-4.36; P = 0.002). The SS-II demonstrated a higher predictive accuracy for 5-year mortality compared with the SS alone (the area under the ROC curve was 0.705 and 0.598, respectively).</p><p><b>CONCLUSION</b>The SS-II is an independent predictor of 5-year mortality in patients with three-vessel CAD undergoing PCI treated with second-generation DES, and demonstrates a superior predictive ability over the SS alone.</p>

RESUMEN
Objective To explore the mechanism of reactive oxygen species (ROS) generation on apoptosis of human osteoarthritic chondrocytes induced by cyclic stretch in vitro. Methods The human osteoarthritic chondrocytes were subjected to cyclic stretch at the frequency of 0.5 Hz with 20% elongation. The chondrocytes without cyclic stretch were used as a control. ROS generation in chondrocytes was inhibited by the antioxidant, N-acetyl-L-cysteine (NAC) and potentiated by the glutathione depleter, DL-buthionine-[S,R]-sulfoximine (BSO). Apoptosis was detected by flow cytometry. Intracellular ROS was detected using DCFH-DA and caspase-9 activity was measured using spectrophotometry. Results The cyclic stretch at the frequency of 0.5 Hz with 20% elongation induced ROS generation, and activation of caspase-9 and apoptosis in human osteoarthritic chondrocytes were significantly increased (P<0.05). The inhibition or potentiation of intracellular ROS by NAC or BSO could obviously inhibit or improve caspase-9 activity and apoptosis in chondrocytes under cyclic stretch (P<0.05). Conclusions Cyclic stretch-induced apoptosis in human osteoarthritic chondrocytes is mediated by ROS generation and activation of caspase-9. Suppression of ROS can prevent chondrocytes from apoptosis induced by cyclic stretch.
