Objectives To examine the association between tea consumption and depressive symptoms in Chinese older people and to explore the mediating role of cerebrovascular disease in the association. Design Population-based cross-sectional study. Setting A rural community near Qufu in Shandong, China. Participants Community-dwelling individuals aged 60 and older (mean 68.6; 59.3% female) from the Confucius Hometown Aging Project (N = 1,368). Measurments Data were collected through interviews, clinical examinations, and psychological testing, following a standard procedure. Presence of high depressive symptoms was defined as a score of 5 or greater on the 15-item Geriatric Depression Scale. Results Of the 1,368 participants, 165 (12.1%) were weekly and 489 (35.7%) were daily tea consumers. Compared with no or irregular tea consumption, controlling for age, sex, education, leisure activities, number of comorbidities, and Mini-Mental State Examination score, the odds ratios of having high depressive symptoms were 0.86 (95% confidence interval (CI) = 0.56-1.32) for weekly and 0.59 (95% CI = 0.43-0.81) for daily tea consumption (P for linear trend =.001); the linear trend of the association remained statistically significant when further controlling for history of stroke, transient ischemic attacks, and presence of carotid plaques. Conclusions Daily tea consumption is associated with a lower likelihood of depressive symptoms in Chinese older people living in a rural community. The association appears to be independent of cerebrovascular disease and atherosclerosis. © 2013, The American Geriatrics Society.

The aim of this clinical study was to evaluate the efficacy and safety of nab-paclitaxel to treat patients with advanced non-small cell lung cancer (NSCLC) who failed first-line chemotherapy. Eligible patients had advanced NSCLC and had been treated with first-line platinum-based chemotherapy but still had disease progression. Patients received nab-paclitaxel 100 mg/m(2) (i.v.) on days 1, 8 and 15 of a 28-day cycle. Primary endpoint is 6-month progression-free survival (PFS). Fifty-six patients with advanced NSCLC were enrolled in the study (55.4 % male patients, 44.6 % female patients; median age 59.6 years; ranging from 32 to 83 years). Six-month PFS rate was 18 % (95 % CI 7.8-28.7 %). Median PFS was 3.5 months (95 % CI 1.9-5.8 months). Median overall survival was 6.8 months (95 % CI 4.7-9.3 months). No complete responses were achieved. Overall response rate was 16.1 % (95 % CI 8.9-24.7 %). Grade 3 or 4 adverse events (AEs) were observed in patients receiving nab-paclitaxel. The most common grade 3 or 4 AEs were dizziness, pulmonary embolism and fatigue. Nab-paclitaxel showed clinically equivalent efficacy on patients' survivals and response rates, as compared with other FDA-approved second-line chemotherapy agents. Given the tolerability on grade 3 or 4 adverse events, nab-paclitaxel may be considered an alternative second-line treatment option for NSCLC.

Background and purpose: Data on the possible association between cardiac right-to-left shunt (RLS) and cryptogenic stroke are lacking in Asians. RLS and its subtypes in Chinese cryptogenic stroke patients were investigated. Methods: Patients (n = 153, mean age 42 ± 10 years, 81 male) with cryptogenic stroke from four medical centers in China and 135 healthy volunteers (mean age 34 ± 8 years, 54 male) were recruited. Contrast transcranial Doppler was used to assess the prevalence of RLS. A three-level RLS categorization was applied as follows: none, 0 microbubbles (MBs); small, 1-25 MBs; and large, >25 MBs. RLS was considered latent if it occurred only after the Valsalva maneuver or permanent when it occurred also during normal respiration. Results: Overall, RLS (P = 0.02), large RLS (P < 0.001) and permanent RLS (P = 0.02) were more frequently detected in patients with cryptogenic stroke than in healthy volunteers. The prevalences of small RLS and latent RLS in the two groups were similar (22% vs. 21% and 11% vs. 10%, respectively). The proportion of large RLSs amongst the subjects with RLS was much higher in the patient group than in healthy volunteers (45% vs. 18%, P < 0.001), whilst the proportion of permanent RLS was similar (72% vs. 64%, P = 0.11). Most large RLSs in the patient group (22/27, 81%) were permanent RLSs. Conclusions: Cardiac RLS is associated with cryptogenic stroke in Chinese. However, the higher prevalence of overall RLS in the patient group was mainly due to the increased proportion of large RLSs. The results only support large RLSs as a pathological condition. © 2014 The Author(s). European Journal of Neurology © 2014 EFNS.

Aims: We studied the effect of thalidomide on NFκB-induced TNF-α in acute pancreatitis-associated lung injury in the rat. Methods: Rats were intragastrically administered thalidomide (100mg/kg) daily for 8 days and then acute pancreatitis was induced by retrograde infusion of 5% sodium taurocholate into the rat biliopancreatic duct. Serum amylase (AMY), blood oxygen partial pressure (PaO2), ratios of lung wet/dry weight, and cytoplasmic IκBα and TNF-α protein and nuclear NFκBp65 protein were measured. Also, lung NFκBp65 and TNF-α mRNA were measured. Results: Compared with the model group, the pathological score of the pancreas and lung, serum AMY, ratios of lung wet/dry weight, and lung NFκBp65 and TNF-α mRNA and protein of rats given thalidomide were decreased significantly (P<0.01), but PaO2 and IκBα protein was elevated significantly (P<0.01). Conclusion: Thalidomide may inhibit TNF-α expression via down-regulation of the NFκB signaling pathway to alleviate acute pancreatitis-associated lung injury in rats. © 2014 Elsevier GmbH.

Background: The epidemiological scenario of cardiovascular risk factors (CRFs) among elderly people in rural China is unclear.We seek to describe the distribution, burden and management of major CRFs among older Chinese people living in the rural community.Results: The overall prevalence of current smoking, physical inactivity, hypertension, diabetes, high cholesterol and obesity were 13.8%, 83.7%, 76.0%, 26.6%, 42.4% and 13.1%, respectively: 82.8% and 50.4% of participants had ≥2 and ≥3, respectively, of the six CRFs. Prevalence of alcohol consumption was 18.7%. Men were more likely to smoke and consume alcohol than women, whereas women were more likely to be obese and physically inactive than men (p<0.001). Prevalence of physical inactivity and hypertension increased with age, prevalence of alcohol intake and obesity decreased with age, and prevalence of smoking and diabetes was stable. Hypertension, diabetes and high cholesterol were treated in 60.6%, 68.1% and 41.1% of those with the disease, respectively, but only 11.3%, 13.7% and 31.7% achieved good control.Methods: This cross-sectional study included 1538 participants in the Confucius Hometown Aging Project (2010-2011) of people ≥60 years of age (mean age 68.6 years; 59.1% women) who lived in a rural community nearby Qufu, Shandong, China. Data were collected through a face-to-face interview, a clinical examination and laboratory tests. We carried out descriptive analysis on the prevalence and management of major CRFs.Conclusions: CRFs are highly prevalent and poorly controlled among elderly people in rural China, where men and women have different CRF profiles. Intervention programs targeting major CRFs may improve the health of older people in China. © The European Society of Cardiology 2013.

Here we report an oral alkylphospholipid perifosine dramatically sensitizes chemo-resistant ovarian cancer cells to paclitaxel induced cell death and apoptosis in vitro. We found that co-administration perifosine with paclitaxel in human ovarian cancer cells led to the inhibition of AKT/mTOR complex 1 (mTORC1), a marked increase in ceramide and reactive oxygen species (ROS) production, and a striking increase in the activation of pro-apoptosis pathways, including caspase 3, c-Jun N-terminal kinases (JNK) and AMP-activated protein kinase (AMPK). These signaling events together caused a marked increase of cancer cell apoptosis. Combining paclitaxel with perifosine may represent a novel anti-ovarian cancer strategy. © 2011 Elsevier Ireland Ltd.

MicroRNA let-7i is up-regulated in T cells from patients with Ankylosing Spondylitis (AS). In this study, we investigated the role of let-7i in T cells survival. Our results demonstrated down-regulation of insulin-like growth factor-1 receptor (IGF1R) in T cells from patients with AS. Luciferase reporter assay suggested IGF1R as direct target of let-7i. Overexpression of let-7i in Jurkat cells significantly suppressed IGF1R expression, which mimicked the action of IGF1R siRNA. IGF1R inhibition led to a strinking decrease in phosphorylation of mTOR and Akt, down-regulation of Bcl-2, up-regulation of Bax and cleavage of caspase 3 and PARP. Meanwhile, IGF1R inhibition induced autophagy. Autophagy induced by let-7i overexpression contributed to protect cells from apoptosis. Our data indicated that let-7i might control T cells fates in AS by targeting IGF1R. © 2014 Elsevier Inc. All rights reserved.

Purpose: The majority of metastatic melanomas are resistant to diverse chemotherapeutic agents, and long-term survival for patients with melanoma who have metastatic disease is dismal. Consequently, the search for novel anti-melanoma agents is urgent. Here, we evaluate the potential effects of C6 ceramide to sensitize melanoma cell lines (B16 and WM-115 cells) to curcumin-induced cell death. Methods: MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide) assay was used to test melanoma cell viability in vitro. Hoechst 33342 fluorescence and Histone DNA ELISA was used to evaluate melanoma cell apoptosis. Apoptosis-associated proteins in melanoma cells after treatments were measured by Western blot. Results: C6 ceramide promotes curcumin-induced cell death and apoptosis in B16 and WM-115 melanoma cell lines. Curcumin itself promotes pro-apoptosis protein Caspase 3 and Caspase 9 cleavage and anti-apoptosis protein Bcl-XL and X-IAP degradation, and combination of C6 ceramide with curcumin dramatically enhances it. Caspase inhibitors largely inhibit C6-ceramide plus curcumin induced cell death and apoptosis. Conclusion: We suggest that C6 ceramide sensitizes melanoma cell to curcumin induced cell death and apoptosis in vitro, which is due to, at least in part, the augment of mitochondria apoptosis pathway. Combining C6 ceramide with traditional chemotherapy drugs such as curcumin may have potential to be used as a new therapeutic intervention against melanoma. © 2010 Springer-Verlag.

Hyperbaric oxygen preconditioning (HBO-PC) has been demonstrated to attenuate hemorrhagic transformation (HT) after middle cerebral artery occlusion (MCAO) in hyperglycemic rats. However, the mechanisms remain to be illustrated. Recently, HBO-PC has been shown to activate peroxisome proliferator-activated receptor-gamma (PPARγ) by increasing 15d-PGJ2 in primary cultured neurons. We hypothesize that HBO-PC reduces HT by suppressing inflammation through increasing 15d-PGJ2 and activating PPARγ in hyperglycemic MCAO rats. HBO (2.5. ATA) was administered for 1. h daily for 5 consecutive days. The PPARγ inhibitor GW9662 was administered intraperitoneally to designated animals. Infarction volume, hemorrhage volume, neurological scores and mortality were analyzed. The levels of 15d-PGJ2, PPARγ, TNF-α and IL-1β, tight junction proteins as well as the activity of MMP-2 and MMP-9 were evaluated 24. h after MCAO. HBO-PC reduced HT, improved neurological function, down-regulated inflammatory molecules and inhibited the activation of MMP-9 by increasing 15d-PGJ2 and PPARγ at 24. h after MCAO. The results suggested that HBO-PC might be an alternative measure to decrease HT in ischemic stroke. © 2014 Elsevier Inc.

Background/objectives Previous studies have shown an upward trend in the prevalence of hypertension, but data on trend of incidence of hypertension are lacking. We seek to investigate the trends in incidence of hypertension and control of incident hypertension among Chinese adults during 1991-1997 and 2004-2009. Methods Within the China Health and Nutrition Survey (1991-2009), we identified five cohorts of adults (age ≥ 18 years) who were free of hypertension at baseline of each cohort: cohorts 1991-1997 (n = 4107), 1993-2000 (n = 4068), 1997-2004 (n = 4141), 2000-2006 (n = 4695), and 2004-2009 (n = 4523). Data on demographics, smoking, alcohol intake, physical activity, body mass index (BMI), and blood pressure were collected through interviews and clinical examination. Hypertension was defined as blood pressure ≥ 140/90 mmHg or currently using antihypertensive drugs. Multiple generalized estimation equations and Coxregression models were used to test the trends in blood pressure, incidence of hypertension, use of antihypertensive drugs, and control status of incident hypertension. Results After controlling for potential confounders, incidence of hypertension (per 100 person-years) significantly increased from 2.9 in 1991-1997 to 5.3 in 2004-2009 (ptrend = 0.024); the linear trend was statistically or marginally significant in the age group of 18-39 years, in women, in rural residents, and in adults with normal BMI. The overall rates of antihypertensive treatment and control of incident hypertension increased significantly from 5.7% and 1.7% in 1991-1997 to 19.9% and 7.6% in 2004-2009, respectively (ptrend < 0.001). Conclusions The incidence of hypertension has increased in Chinese adults since early 1990s. The treatment and control status of incident hypertension, while improved, remain very poor. © 2014 Elsevier Ireland Ltd.
