Abstract
An increasing number of unruptured intracranial aneurysms (UIAs) has been
discovered in elderly patients in recent years, but the optimal treatment
strategy for these patients remains controversial. We report our six-year
experience treating UIAs in elderly patients (≥ 70 years old). A retrospective
review was conducted of elderly patients who harbored UIAs treated by
conservative observation, microsurgical clipping, or endovascular coiling
between January 2009 and December 2014. The patients’ clinical and imaging
information was recorded. Treating methods, procedure-related complications,
imaging results, and clinical outcomes were analyzed. A total of 141 consecutive
elderly patients with 166 UIAs were enrolled in our study. In all, 64 patients
with 79 aneurysms were treated with coiling, and 14 patients with 14 aneurysms
were treated with clipping. The remaining 63 patients with 73 aneurysms were
placed under conservative observation. The average modified Rankin scale was
0.99 (range 0–6) in the full cohort after a mean follow-up of 50.4 months (range
0–70 months). There was no significant difference of modified Rankin scale in
patients with UIAs treated by different methods. Multivariate analysis showed
that age (p=0.030) and aneurysm size (p=0.011)
were independent risk factors for unfavorable outcome of UIAs in the elderly.
Patient age (p=0.010) and aneurysm size
(p=0.020) were also significantly associated with unfavorable
outcome of UIAs managed with observation initially. Our results indicated that
endovascular coil embolization and clipping were both safe and effective
treatment methods for UIAs in the elderly. Aggressive treatment for UIAs in
elderly patients with risk factors of aneurysm rupture should be considered
positively.

Abstract
Objective: To analyze the composition and richness of intestinal microflora in children with non-alcoholic fatty liver disease (NAFLD) and the role of which in pathogenesis of NAFLD. Methods: This was a prospective case-control study. From November 2015 to June 2017, 19 children diagnosed with NAFLD according to the 2010 edition of diagnostic criteria were enrolled voluntarily in the Second and First Affiliated Hospitals of Zhejiang Chinese Medicine University. Twenty-two healthy children were enrolled in the control group. Among the patients, 10 were males and 9 were females, at the mean age of (11.0±1.0) years; 10 males and 12 females in the control group, at the mean age of (9.0±1.2) years. The body mass index (BMI) and waist circumference were recorded, and the fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein were detected. Feces were collected and the fecal microorganisms were extracted with magnetic beads methods; the composition and the richness of intestinal microflora in the two groups were detected with 16S rDNA high throughput sequencing technology. The KO differential gene expression and KEGG signal pathway enrichment were analyzed with PICRUST software. The intestinal flora characteristics between the two groups were compared with t test or Mann-Whitney U test and Willcoxon W test. Results: The BMI, waist circumference and triglyceride were higher in NAFLD group than those in the control group (BMI (25.1±2.7) vs. (18.2±1.5)kg/m(2), t=9.912, P=0.000; waist circumference (88.6±6.6) vs. (71.5±6.3) cm, t=8.520, P=0.000; triglyceride (0.9±0.4) vs.(0.7±0.3)mmol/L, t=2.060, P=0.046). The abundance and diversity index of intestinal microflora were lower in the NAFLD group (Shannon index 3.99 (3.13, 4.54) vs. 4.63 (4.21, 4.81), Z=-2.065, P=0.039; Simpson index 0.85 (0.70, 0.89) vs. 0.90 (0.88, 0.93), Z=-2.431, P=0.015; ACE index 235.76 (205.26, 361.94) vs. 326.96 (275.34, 368.65), Z=-2.092, P=0.036). At the level of phylum, the proportion of Actinomycetes was lower and the proportion of Thermus was higher in NAFLD group (Actinobacteri 29.807 (14.723, 62.080) ×10(-3) vs. 63.212 (46.133, 172.071) ×10(-3), Z=-2.667, P=0.008; Thermus 0.033 (0.000, 0.226) ×10(-3) vs. 0.000 (0.000, 0.031) ×10(-3), Z=-2.729, P=0.006) . At the level of genus, the proportion of Bacteroides and Bifidobacterium in the NAFLD group were significantly lower (Bacteroides 78.757 (11.430, 151.621) ×10(-3) vs. 356.821 (161.049, 403.037) ×10(-3), Z=-2.771, P=0.006; Bifidobacterium 19.680 (6.181, 53.944) ×10(-3) vs. 54.721 (31.911, 146.410) ×10(-3), Z=-2.458, P=0.014); the proportion of Prevotella in NAFLD group was significantly higher (3.089 (0.165, 63.502) ×10(-3) vs. 0.432 (0.029, 2.257) ×10(-3), Z=-2.112, P=0.035). Based on the KEGG database, 78 differentially expressed genes and 26 differential metabolic pathways were found, among which the function genes of K01470, K01961 and K07258 were concentrated in the pathways of arginine and proline metabolism, fatty acid synthesis, and polysaccharides biosynthesis and metabolism. Besides, these three function genes were related to Bacteroides, Prevotella, Bifidobacterium and Ruminococcus. Conclusion: NAFLD children have intestinal flora disturbances in both diversity and abundance, which may alter lipid metabolic pathways through differential gene expressions, contributing to the pathogenesis of NAFLD.

Abstract
Juvenile amyotrophic lateral sclerosis (JALS) occurs at an age of onset below 25 years with a heterogeneous disease onset location, variable progression and survival time. To investigate whether an ALS gene profile could resolve any aspects of clinical symptom heterogeneity, we have used targeted sequencing technology in a cohort of 12 JALS patients of Chinese descent. We detected 5 likely pathogenic mutations, 2 in familial probands and 3 in sporadic patients. One was a known TARDBP mutation (p.G348V) and 4 were FUS frameshift mutations including a known p.Gln519Ilefs*9 mutation and 3 novel mutations, p.Gly515Valfs*14, p.Gly486Profs*30, and p.Arg498Alafs*32. Of the 4 FUS mutations, 2 were able to be confirmed as de novo mutations. The TARDBP mutation carrier showed a classic ALS phenotype. All patients with FUS mutations experienced limb weakness at an early age and developed bulbar symptoms during the disease course. FUS mutations have previously been associated with increased JALS disease progression, however, we found a large range 12 to 84 months in disease survival (mean 58.2 months). Our results justify future screening for variants in FUS as it remains the most frequent genetic determinant of early onset, JALS (found in 30% of our patients).

Abstract
UNLABELLED This study used a simulation model to determine the cost-effective threshold of fracture risk to treat osteoporosis among elderly Chinese women. Osteoporosis treatment is cost-effective among average-risk women who are at least 75 years old and above-average-risk women who are younger than 75 years old. INTRODUCTION Aging of the Chinese population is imposing increasing economic burden of osteoporosis. This study evaluated the cost-effectiveness of osteoporosis treatment among the senior Chinese women population. METHODS A discrete event simulation model using age-specific probabilities of hip fracture, clinical vertebral fracture, wrist fracture, humerus fracture, and other fracture; costs (2015 US dollars); and quality-adjusted life years (QALYs) was used to assess the cost-effectiveness of osteoporosis treatment. Incremental cost-effectiveness ratio (ICER) was calculated. The willingness to pay (WTP) for a QALY in China was compared with the calculated ICER to decide the cost-effectiveness. To determine the absolute 10-year hip fracture probability at which the osteoporosis treatment became cost-effective, average age-specific probabilities for all fractures were multiplied by a relative risk (RR) that was systematically varied from 0 to 10 until the WTP threshold was observed for treatment relative to no intervention. Sensitivity analyses were also performed to evaluate the impacts from WTP and annual treatment costs. RESULTS In baseline analysis, simulated ICERs were higher than the WTP threshold among Chinese women younger than 75, but much lower than the WTP among the older population. Sensitivity analyses indicated that cost-effectiveness could vary due to a higher WTP threshold or a lower annual treatment cost. A 30 % increase in WTP or a 30 % reduction in annual treatment costs will make osteoporosis treatment cost-effective for Chinese women population from 55 to 85. CONCLUSIONS The current study provides evidence that osteoporosis treatment is cost-effective among a subpopulation of Chinese senior women. The results also indicate that the cost-effectiveness of using osteoporosis treatment is sensitive to the WTP threshold and annual treatment costs.

Abstract
OBJECTIVE To observe the expression of neural axon guidance molecules Slit3 and Robo receptors in mouse aortic smooth muscle cell(MASMC) and investigate the effect of exogenous Slit3 protein on migration and proliferation of MASMC. METHODS The primary cultured MASMC were identified by immunofluorescent assay. The expression of Slit3/Robo signal pathway was detected by RT-PCR and immunocytochemical staining. MASMC were divided into 6 groups: the negative control group (DMEM medium containing bovine serum albumin 86 μg/L), Slit3 0 μg/L group (DMEM medium without Slit3), Slit3 24 μg/L group (DMEM medium containing Slit3 24 μg/L), Slit3 40 μg/L group (DMEM medium containing Slit3 40 μg/L), Slit3 80 μg/L group (DMEM medium containing Slit3 80 μg/L) and the positive control group (DMEM medium containing platelet derived growth factor 10 μg/L). The effects of exogenous Slit3 on MASMC proliferation and migration were detected by CCK-8 and scratched cells and transwell chambers respectively. RESULTS (1) The mRNA and protein expressions of Slit2, Slit3, Robo1 and Robo4 were detected in MASMC. mRNA level of Slit2 was lower than Slit3 (P<0.05) and there were no significant difference between mRNA level of Robo1 and Robo4. (2) The mitogenic responses of MASMC were significantly enhanced in Slit3 24 μg/L group, Slit3 40 μg/L group and Slit3 80 μg/L group compared with negative control group (1.13±0.04, 1.19±0.02, 1.18±0.08 and 0.64±0.10 respectively, all P<0.05). The mitogenic activity of MASMC was the strongest in Slit3 40 μg/L group (compared with positive control group 1.27±0.05, P>0.05). (3)The autonomous migration activity of MASMC were significantly increased in Slit3 24 μg/L group, Slit3 40 μg/L group, Slit3 80 μg/L group compared with negative control group (cell scratch width were (0.40±0.03)cm, (0.32±0.03)cm, (0.30±0.02)cm and (0.49±0.01)cm respectively, all P<0.05). The autonomous migration activity of MASMC was the strongest in Slit3 80 μg/L group (compared with positive control group (0.22±0.01)cm, P>0.05). The transmembrane migration activity of MASMC were significantly increased in Slit3 24 μg/L group, Slit3 40 μg/L group, Slit3 80 μg/L group compared with negative control group (the number of cell migration were 46.67±2.23, 65.33±3.43, 81.67±4.22 and 39.33±2.03 respectively, all P<0.05). The transmembrane migration activity of MASMC was the strongest in Slit3 80 μg/L group (compared with positive control group 84.00±2.02, P>0.05). CONCLUSION Slit2, Slit3, Robo1 and Robo4 were expressed in MASMC, and exogenous Slit3 could promote proliferation and migration of MASMC in vitro.

Abstract
Recent studies have reported the role of Wnt/β-catenin signaling in hair cell (HC) development, regeneration, and differentiation in the mouse cochlea; however, the role of Wnt/β-catenin signaling in HC protection remains unknown. In this study, we took advantage of transgenic mice to specifically knockout or overactivate the canonical Wnt signaling mediator β-catenin in HCs, which allowed us to investigate the role of Wnt/β-catenin signaling in protecting HCs against neomycin-induced damage. We first showed that loss of β-catenin in HCs made them more vulnerable to neomycin-induced injury, while constitutive activation of β-catenin in HCs reduced HC loss both in vivo and in vitro. We then showed that loss of β-catenin in HCs increased caspase-mediated apoptosis induced by neomycin injury, while β-catenin overexpression inhibited caspase-mediated apoptosis. Finally, we demonstrated that loss of β-catenin in HCs led to increased expression of forkhead box O3 transcription factor (Foxo3) and Bim along with decreased expression of antioxidant enzymes; thus, there were increased levels of reactive oxygen species (ROS) after neomycin treatment that might be responsible for the increased aminoglycoside sensitivity of HCs. In contrast, β-catenin overexpression reduced Foxo3 and Bim expression and ROS levels, suggesting that β-catenin is protective against neomycin-induced HC loss. Our findings demonstrate that Wnt/β-catenin signaling has an important role in protecting HCs against neomycin-induced HC loss and thus might be a new therapeutic target for the prevention of HC death.

Abstract
This study aimed to assess the efficacy of a rural community-based integrated
intervention for early prevention and management of chronic obstructive pulmonary
disease (COPD) in China. This 18-year cluster-randomized controlled trial
encompassing 15 villages included 1008 patients (454 men and 40 women in the
intervention group [mean age, 54 ± 10 years]; 482 men and 32 women in the control
group [mean age, 53 ± 10 years]) with confirmed COPD or at risk for COPD. Villages
were randomly assigned to the intervention or the control group, and study
participants residing within the villages received treatment accordingly.
Intervention group patients took part in a program that included systematic health
education, smoking cessation counseling, and education on management of COPD. Control
group patients received usual care. The groups were compared after 18 years regarding
the incidence of COPD, decline in lung function, and mortality of COPD. COPD
incidence was lower in the intervention group than in the control group (10%
vs 16%, <0.05). A decline in lung function was also
significantly delayed in the intervention group compared to the control group of COPD
and high-risk patients. The intervention group showed significant improvement in
smoking cessation compared with the control group, and smokers in the intervention
group had lower smoking indices than in the control group (350 vs
450, <0.05). The intervention group also had a significantly lower cumulative
COPD-related death rate than the control group (37% vs 47%,
<0.05). A rural community-based integrated intervention is effective in reducing
the incidence of COPD among those at risk, delaying a decline in lung function in
COPD patients and those at risk, and reducing mortality of COPD.

Eye (Lond) 2015; 29:1545-54. [PMID: 26272444 DOI: 10.1038/eye.2015.147] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2015] [Accepted: 06/29/2015] [Indexed: 11/09/2022] Open
Abstract
PURPOSE Real-Life Vision Test (RLVT) is a newly developed performance-based measures of functional vision. This present study is designed to determine whether it could be a meaningful assessment for cataract surgery outcomes evaluation. PATIENTS AND METHODS Age-related cataract patients (56) who scheduled for bilateral cataract surgery and 44 age-matched controls were evaluated by four types of measurements: (1) demographic, medical, cognitive and depressive evaluation, and the reaction time testing; (2) clinical measures (visual acuity, contrast sensitivity, stereopsis, and color perception); (3) the 25-item National Eye Institute's Visual Functioning Questionnaire (NEI-VFQ); (4) the RLVT. Spearman's coefficients and multiple regression analysis were conducted to investigate the relationship among RLVT, clinical measures, and self-report assessment of visual function. RESULTS The results of RLVT, clinical measures, and NEI-VFQ total scores were improved significantly after cataract surgery. There were no differences between control subjects and post-surgery patients with respect to NEI-VFQ-25 total scores, self-rating depression scale scores and three tasks of RLVT. Change of RLVT was significantly associated with the change of clinical measures in the cataract group. Multiple regression analysis demonstrated that change of distance, intermediate, and near visual acuity, and binocular contrast sensitivity were significant predictors of improvements of RLVT. CONCLUSIONS Cataract surgery could improve real-world visual ability effectively for cataract patients. Our study highlights the potential usefulness of RLVT as an adjunct to the current outcomes evaluation system for cataract surgery. The use of RLVT combined with clinical and self-survey methods may be the comprehensive strategy to manifest the impact of cataract surgery on patients' overall vision-related quality of life.

Effect of sperm DNA fragmentation on the clinical outcomes for in vitro fertilization and intracytoplasmic sperm injection in women with different ovarian reserves. Fertil Steril 2015; 103:910-6.

Abstract
OBJECTIVE To investigate effect of sperm DNA fragmentation (SDF) on clinical outcomes of assisted reproductive technology in women with normal ovarian reserve (NOR) versus reduced ovarian reserve (ROR). DESIGN Retrospective clinical study. SETTING University-affiliated tertiary teaching hospital. PATIENT(S) A total of 2,865 consecutive couples undergoing their first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle. INTERVENTION(S) SDF assessed using sperm chromatin dispersion in sperm samples 1-2 months before treatment. MAIN OUTCOME MEASURE(S) SDF, IVF, and ICSI outcomes. RESULT(S) The grouping criteria were [1] basal follicle stimulating hormone >10 IU/L, [2] antral follicle count <6, and [3] female age ≥38 years. Women fulfilling two of the three criteria were considered to have ROR, and those not meeting any criteria were considered to have NOR. The area under the receiver operating characteristic curve was 0.594 (0.539-0.648) for the ROR group and 0.510 (0.491-0.530) for the NOR group. A cutoff value for SDF to predict the clinical pregnancy rate (CPR) in the ROR group was 27.3%. When the SDF exceeded 27.3%, the live-birth and implantation rates in the ROR group were statistically significantly decreased, but the clinical pregnancy, live-birth, and implantation rates were not affected in the NOR group. The risk of early abortion increased significantly in the NOR group when the SDF exceeded 27.3%. CONCLUSION(S) Sperm DNA fragmentation has a greater impact on IVF and ICSI outcomes among women with ROR, so SDF testing may be of particular clinical significance for these couples.

Abstract
Reactive oxygen species (ROS) accumulation are involved in noise- and ototoxic drug-induced hair cell loss, which is the major cause of hearing loss. Bmi1 is a member of the Polycomb protein family and has been reported to regulate mitochondrial function and ROS level in thymocytes and neurons. In this study, we reported the expression of Bmi1 in mouse cochlea and investigated the role of Bmi1 in hair cell survival. Bmi1 expressed in hair cells and supporting cells in mouse cochlea. Bmi1−/− mice displayed severe hearing loss and patched outer hair cell loss from postnatal day 22. Ototoxic drug-induced hair cells loss dramatically increased in Bmi1−/− mice compared with that in wild-type controls both in vivo and in vitro, indicating Bmi1−/− hair cells were significantly more sensitive to ototoxic drug-induced damage. Cleaved caspase-3 and TUNEL staining demonstrated that apoptosis was involved in the increased hair cell loss of Bmi1−/− mice. Aminophenyl fluorescein and MitoSOX Red staining showed the level of free radicals and mitochondrial ROS increased in Bmi1−/− hair cells due to the aggravated disequilibrium of antioxidant–prooxidant balance. Furthermore, the antioxidant N-acetylcysteine rescued Bmi1−/− hair cells from neomycin injury both in vitro and in vivo, suggesting that ROS accumulation was mainly responsible for the increased aminoglycosides sensitivity in Bmi1−/− hair cells. Our findings demonstrate that Bmi1 has an important role in hair cell survival by controlling redox balance and ROS level, thus suggesting that Bmi1 may work as a new therapeutic target for the prevention of hair cell death.

Abstract
1-Methylpropyl 2-imidazolyl disulfide (PX-12) has been proposed as an inhibitor of thioredoxin-1 (Trx-1) with antitumor activity. However, the antitumor activity of the Trx-1 redox signaling inhibitor PX-12 on colorectal cancer is still obscure. In the present study, we showed that PX-12 inhibited the growth of colorectal cancer DLD-1 and SW620 cells in a dose- and time-dependent manner. Further analysis demonstrated that PX-12 reduced cell colony formation and induced a G2/M phase arrest of the cell cycle. In addition, PX-12 treatment induced apoptosis, as observed by the increased number of Annexin V-positive cells and increased activation of caspase-3. Notably, a low dose of PX-12 inhibited colorectal cancer cell migration and invasion. Treatment of cancer cells with PX-12 reduced NOX1, CDH17 and S100A4 mRNA expression, and increased KLF17 mRNA expression. Moreover, PX-12 decreased S100A4 protein expression in the colorectal cancer cells. Collectively, the present study demonstrates the antitumor effects and therapeutic potential of PX-12 in colorectal cancer.
