Abstract
Objective: To analyze the disease burden of falls in Chinese population aged 70 and over, in 1990 and 2013 and to provide evidence for the development of prevention strategies on falls in the elderly. Methods: Indicators including mortality rate, years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted of life years (DALY) on falls, were gathered from the results of Global Burden of Disease 2013 and used to describe the disease burden of falls in China by calculating the changing rates on corresponding parameters in 1990 and 2013. Results: In 2013, the number of deaths, YLLs, YLDs, DALYs caused by falls among Chinese population aged 70 and over were 48 800, 0.44 million person years, 0.30 millions person years, and 0.74 million person years, respectively. The standardized mortality rate, rates on YLLs, YLDs and DALYs of falls were 561.71 per 100 000, 55.87 per 100 000, 373.98 per 100 000 and 929.85 per 100 000, respectively. The burden of falls increased along with the increase of age. Compared with 1990, the number of deaths, YLLs, YLDs and DALYs caused by falls increased by 308.80%, 161.01%, 54.67% and 104.47%, respectively, in 2013, more seen in males than in females. The standardized mortality rate, YLLs and DALYs caused by falls increased by 63.67%, 38.54% and 73.08%, respectively, during 1990 and 2013. However, the standardized YLDs rate fell by 17.90% during the same period. Conclusion: Falls caused heavy disease burden which increased in 1990 and 2013 among the Chinese population aged 70 and over.

Abstract
Objective: To provide basic suicide prevention strategy through analyzing the disease burden of suicide in the Chinese population, in 1990 and 2013. Methods: Indicators including mortality rate, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted of life years (DALY) on suicide, were from the results of Global Burden of Disease 2013 and used to describe the burden of disease caused by suicide in Chinese population. Data described the disease burden of suicide in China by comparing the corresponding parameters in 1990 and 2013. Results: In 2013, the standard mortality on suicide was 9.08 per 100 000, and 73.39 per 100 000 in the 80 and above year-old, with the highest rates on DALY and YLL seen in the 75-79-year-old. Each parameter related to suicide burden in males appeared higher than that in females. Compare to data in the 1990s, these parameters declined in 2013, especially seen in females. The rate of YLLs/YLDs on suicide was 90.03 in 2013, 89.83 in males and 89.00 in females. Conclusion: The disease burden of suicide decreased sharply between 1990 and 2013 but was still a serious issue in the elderly that called for more attention.

Abstract
Objective: To assess the 3-year antibody persistence after vaccination of domestic measles, mumps and rubella combined attenuated live vaccine (MMR) with different program. Methods: Children from three different vaccination strategies (Group 8 m MR: 8 months and 18 months vaccinated with measles-rubella combined attenuated live vaccine and domestic MMR,respectively; Group 8 m MMR: 8 months and 18 months both vaccinated with domestic MMR; Group 12 m MMR: 12 months and 22 months both vaccinated with domestic MMR ) were followed up in Zhejiang province in July 2015. There were 170 participants in Group 8 m MR, 171 participants in Group 8 m MMR and 173 participants in Group 12 m MMR selected by simple random sampling method .Blood samples (venous blood 2-3 ml) were collected 1 month after the first dose vaccination of MMR (only in Group 8 m MMR and Group 12 m MMR) and 3 years (36-38 months) after the last dose vaccination of MMR and tested for antibody IgG against Measles, Mumps and Rubella using ELISA. Seropostive rate and Geometric mean concentration (GMC) were calculated and compared among different groups by Chi-square test or Fisher exact test and Kruskal-Wallis H test. Results: A total of 514 participants (8 m MR: 170; 8 m MMR:171; 12 m MMR:173) were enrolled. The overall seropositivity rate of measles, mumps and rubella was 98.1% (504), 93.4% (480) and 88.1% (453), respectively, with corresponding GMC was 1 012.33 mU/ml, 502.87 U/ml and 50.53 U/ml respectively. There was no significant difference of seropositivity rate for measles among three groups (all groups were>97%). The highest seropositivity rate for mumps was found in the Group 12 m MMR with the rate of 98.8% (171/173), followed by Group 8 m MMR and Group 8 m MR with 93.0% (159/171) and 88.2%(150/170) respectively (Fisher exact test, P<0.001). The highest seropositivity rate for rubella was also found in the Group 12 m MMR with the rate of 94.8% (164/173), followed by Group 8 m MMR and Group 8 m MR with 86.6%(148/171) and 82.9%(141/170) respectively (Fisher exact test, P=0.002). The highest GMC of antibody against measles, mumps and rubella were all found in Group 12 m MMR, with 1 217.30 (1 119.35-1 323.82) mU/ml, 717.07 (643.83-798.65) U/ml and 62.54(56.21-69.58) U/ml respectively. The lowest GMC of antibody against measles and mumps were both in Group 12 m MR with 812.01 (734.52-897.67) mU/ml and 363.28 (305.42-432.11) U/ml respectively. The lowest GMC of antibody against rubella was in Group 8 m MMR with 44.10 (39.08-49.76) U/ml. These differences of GMCs among three groups were all reach significant means (P<0.05). Conclusion: High level seropostive rates and GMCs were exist against measles and rubella after 3-year vaccination of domestic MMR among different program. Higher antibody level against mumps were found in those children with two doses vaccination of MMR.

Abstract
We report unambiguous in situ observation of the coalescence of macroscopic flux ropes by the magnetospheric multiscale (MMS) mission. Two coalescing flux ropes with sizes of ∼1 R_{E} were identified at the subsolar magnetopause by the occurrence of an asymmetric quadrupolar signature in the normal component of the magnetic field measured by the MMS spacecraft. An electron diffusion region (EDR) with a width of four local electron inertial lengths was embedded within the merging current sheet. The EDR was characterized by an intense parallel electric field, significant energy dissipation, and suprathermal electrons. Although the electrons were organized by a large guide field, the small observed electron pressure nongyrotropy may be sufficient to support a significant fraction of the parallel electric field within the EDR. Since the flux ropes are observed in the exhaust region, we suggest that secondary EDRs are formed further downstream of the primary reconnection line between the magnetosheath and magnetospheric fields.

Abstract
BACKGROUND Intracerebral hemorrhage (ICH) induces potently oxidative stress responses and inflammatory processes. Isoliquiritigenin (ILG) is a flavonoid with a chalcone structure and can activate nuclear factor erythroid-2 related factor 2 (Nrf2)-mediated antioxidant system, negatively regulate nuclear factor-κB (NF-κB) and nod-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome pathways, but its role and potential molecular mechanisms in the pathology following ICH remain unclear. The present study aimed to explore the effects of ILG after ICH and underlying mechanisms. METHODS ICH model was induced by collagenase IV (0.2 U in 1 μl sterile normal saline) in male Sprague-Dawley rats weighing 280-320 g. Different doses of ILG (10, 20, or 40 mg/kg) was administrated intraperitoneally at 30 min, 12 h, 24 h, and 48 h after modeling, respectively. Rats were intracerebroventricularly administrated with control scramble small interfering RNA (siRNA) or Nrf2 siRNA at 24 h before ICH induction, and after 24 h, ICH model was established with or without ILG (20 mg/kg) treatment. All rats were dedicated at 24 or 72 h after ICH. Neurological deficits, histological damages, brain water content (BWC), blood-brain barrier (BBB) disruption, and neuronal degeneration were evaluated; quantitative real-time RT-PCR (qRT-PCR), immunohistochemistry/immunofluorescence, western blot, and enzyme-linked immunosorbent assay (ELISA) were carried out; catalase, superoxide dismutase activities and reactive oxygen species (ROS), and glutathione/oxidized glutathione contents were measured. RESULTS ILG (20 and 40 mg/kg) markedly alleviated neurological deficits, histological damages, BBB disruption, brain edema, and neuronal degeneration, but there was no significant difference between two dosages. ILG (20 mg/kg) significantly suppressed the NF-κB and NLRP3 inflammasome pathways and activated Nrf2-mediated antioxidant system. Gene silencing of Nrf2 aggravated the neurological deficits, brain edema, and neuronal degeneration and increased the protein levels of NF-κB p65, NLRP3 inflammasome components, and IL-1β. ILG delivery significantly attenuated the effects of Nrf2 siRNA interference mentioned above. CONCLUSIONS Intraperitoneal administration of ILG after ICH reduced early brain impairments and neurological deficits, and the mechanisms were involved in the regulation of ROS and/or NF-κB on the activation of NLRP3 inflammasome pathway by the triggering of Nrf2 activity and Nrf2-induced antioxidant system. In addition, our experimental results may make ILG a potential candidate for a novel therapeutical strategy for ICH.

Abstract
'Candidatus Liberibacter asiaticus' (CLas), an α-proteobacterium, is associated with citrus Huanglongbing (HLB; yellow shoot disease). In California, two cases of CLas have been detected in Los Angeles County, one in Hacienda Heights in 2012 and the other in San Gabriel in 2015. Although all infected trees were destroyed in compliance with a state mandate, citrus industry stakeholder concerns about HLB in California are high. Little is known about the biology of CLas, particularly the California strains, hindering effective HLB management efforts. In this study, next-generation sequencing technology (Illumina MiSeq) was employed to characterize the California CLas strains. Data sets containing >4 billion (Giga) bp of sequence were generated from each CLas sample. Two prophages (P-HHCA1-2 and P-SGCA5-1) were identified by the MiSeq read mapping technique referenced to two known Florida CLas prophage sequences, SC1 and SC2. P-HHCA1-2 was an SC2-like or Type 2 prophage of 38,989 bp in size. P-SGCA5-1 was an SC1-like or Type 1 prophage of 37,487 bp in size. Phylogenetic analysis revealed that P-HHCA1-2 was part of an Asiatic lineage within the Type 2 prophage group. Similarly, P-SGCA5-1 was part of an Asiatic lineage within Type 1 prophage group. The Asiatic relatedness of both P-HHCA1-2 and P-SGCA5-1 was further presented by single nucleotide polymorphism analysis at terL (encoding prophage terminase) that has been established for CLas strain differentiation. The presence of different prophages suggests that the two California CLas strains could have been introduced from different sources. An alternative explanation is that there was a mixed CLas population containing the two types of prophages, and limited sampling in a geographic region may not accurately depict the true CLas diversity. More accurate pathway analysis may be achieved by including more strains collected from the regions.

Abstract
OBJECTIVES Understanding the prevalence of cardiovascular disease (CVD) risk factors has an impact on the public policy for initiating CVD prevention. This study aimed to examine the prevalence of current smoking, overweight/obesity, hypertension, diabetes mellitus (DM), and dyslipidemia among Shenzhen residents and to investigate gender differences in CVD risk profiles to identify the subgroups at higher risk. STUDY DESIGN A large cross-sectional study was conducted between April and May 2015. METHODS Using multistage cluster random sampling methods, a total of 1784 residents finished the face-toface interview survey. Physical examinations and blood tests were performed by qualified professionals. RESULTS The prevalence of current smoking, overweight/obesity, hypertension, DM, and dyslipidemia were 21.8%, 40.6%, 17.6%, 4.8%, and 35.7%, respectively. Clustering of two or more or three or more of CVD risk factors was noted in 35.7% and 14.1% of participants. The prevalence of current smoking (45.0% vs 1.1%, P < 0.001), overweight/obesity (48.5% vs 33.4%, P < 0.001), hypertension (19.7% vs 15.7%, P < 0.05), and dyslipidemia (46.5% vs 20.5%, P < 0.001) was found higher among male than among female participants. CONCLUSIONS This study adds to the evidence suggesting high prevalence rates of CVD risk factors and composite measures among Shenzhen residents. The higher level of CVD risk factors in male than in female residents is suggested. Effective population-based intervention programs such as smoking cessation, early detection, management, and treatment of hypertension, DM, and dyslipidemia should be initiated and enhanced especially among the males.

Abstract
Protein arginine methyltransferase 5 (PRMT5) is an emerging epigenetic enzyme that mainly represses transcription of target genes via symmetric dimethylation of arginine residues on histones H4R3, H3R8 and H2AR3. Accumulating evidence suggests that PRMT5 may function as an oncogene to drive cancer cell growth by epigenetic inactivation of several tumor suppressors. Here, we provide evidence that PRMT5 promotes prostate cancer cell growth by epigenetically activating transcription of the androgen receptor (AR) in prostate cancer cells. Knockdown of PRMT5 or inhibition of PRMT5 by a specific inhibitor reduces the expression of AR and suppresses the growth of multiple AR-positive, but not AR-negative, prostate cancer cells. Significantly, knockdown of PRMT5 in AR-positive LNCaP cells completely suppresses the growth of xenograft tumors in mice. Molecular analysis reveals that PRMT5 binds to the proximal promoter region of the AR gene and contributes mainly to the enriched symmetric dimethylation of H4R3 in the same region. Mechanistically, PRMT5 is recruited to the AR promoter by its interaction with Sp1, the major transcription factor responsible for AR transcription, and forms a complex with Brg1, an ATP-dependent chromatin remodeler, on the proximal promoter region of the AR gene. Furthermore, PRMT5 expression in prostate cancer tissues is significantly higher than that in benign prostatic hyperplasia tissues, and PRMT5 expression correlates positively with AR expression at both the protein and mRNA levels. Taken together, our results identify PRMT5 as a novel epigenetic activator of AR in prostate cancer. Given that inhibiting AR transcriptional activity or androgen synthesis remains the major mechanism of action for most existing anti-androgen agents, our findings also raise an interesting possibility that targeting PRMT5 may represent a novel approach for prostate cancer treatment by eliminating AR expression.

Abstract
Epithelial ovarian cancer (EOC) is one of the most common gynecological cancers, with diagnosis often at a late stage. Metastasis is a major cause of death in patients with EOC, but the underlying molecular mechanisms remain obscure. Here, we utilized an integrated approach to find potential key transcription factors involved in ovarian cancer metastasis and identified STAT4 as a critical player in ovarian cancer metastasis. We found that activated STAT4 was overexpressed in epithelial cells of ovarian cancer and STAT4 overexpression was associated with poor outcome of ovarian cancer patients, which promoted metastasis of ovarian cancer in both in vivo and in vitro. Although STAT4 mediated EOC metastasis via inducing epithelial-to-mesenchymal transition (EMT) of ovarian cancer cells in vivo, STAT4 failed to induce EMT directly in vitro, suggesting that STAT4 might mediate EMT process via cancer-stroma interactions. Further functional analysis revealed that STAT4 overexpression induced normal omental fibroblasts and adipose- and bone marrow-derived mesenchymal stem cells to obtain cancer-associated fibroblasts (CAF)-like features via induction of tumor-derived Wnt7a. Reciprocally, increased production of CAF-induced CXCL12, IL6 and VEGFA within tumor microenvironment could enable peritoneal metastasis of ovarian cancer via induction of EMT program. In summary, our study established a model that STAT4 promotes ovarian cancer metastasis via tumor-derived Wnt7a-induced activation of CAFs.

Abstract
BACKGROUND Congenital cataract is a common cause of childhood vision impairment or blindness with genetic and clinical heterogeneity. The aim of this study was to identify the disease-associated gene in a Chinese family with congenital cataract. METHODS A four-generation Chinese family with three enrolled patients suffering from congenital cataract was studied. Detailed family history and clinical data of all the members were collected and recorded. Exome sequencing was applied in the proband to screen potential genetic variants, and then Sanger sequencing was used to verify the variant within the family. RESULTS A heterozygous variant, c.3673G > A (p.V1225M), in the periaxin gene (PRX) was identified in three patients and two asymptomatic individuals of the family. The variant was absent in the other three unaffected family members and in 3290 ethnically matched in-house controls from BGI-Shenzhen. CONCLUSIONS By utilizing both exome sequencing and Sanger sequencing, we identified a missense variant in the PRX gene that is possibly associated with disease in this family. Our finding may broaden the spectrum of genes associated with congenital cataract, and may provide insights into lens development, pathogenic mechanism, future clinical genetic diagnosis and therapy of congenital cataract.

Abstract
Objective: To evaluate the efficacy of large spot indirect ophthalmoscopy laser alone or combined with systemic chemotherapy in the treatment of early and middle stage retinoblastoma. Methods: Retrospective series case study. Clinical data of 21 patients (22 eyes) who were diagnosed as retinoblastoma (RB) in Peking University People's Hospital from March 2009 to August 2014 were collected. Medical and family history, ocular ultrasound, orbital and cranial MRI or CT examination of RB Children were detailed recorded. Ocular examination and laser treatment were performed under general anesthesia, once every 3-4 weeks until the tumor was under control. The observation period was at least 3 months after the last treatment. The ocular examination included intraocular pressure measurement, anterior segment and fundus examination and the fundus photography with Retcam. Laser therapeutic instrument was large spot indirect ophthalmoscopy laser of 810nm wavelength. Results: Of the 21 children, 16 were male and 5 were female. The range of age was 3 to 82 months averaged 17.3 months. Among 22 eyes, four with small tumor, eight with medium tumor, and ten with large tumor. Two eyes underwent laser treatment only and 20 eyes underwent laser treatment combined with systemic chemotherapy. During the average observation period of 33.9 months, 15 tumors were treated successfully, but 7 failed. The total success rate was 68.2%. The number and success rate of small, medium and large tumor eyes were 4 (100%), 5 (62.5%) and 5 (50%), respectively. There was one case of tumor brain metastases, and the classification of contralateral eye of the child was E phase. COMPLICATIONS Iris burns happened in one eye, obvious vitreous proliferation in one eye and mild vitreous hemorrhage occurred in two eyes, which did not affect the treatment of laser. However, obvious tumor hemorrhage happened in two eyes and affected laser therapy. There was no complicated cataract, iatrogenic retinal hole and tumor intravitreal implant caused by laser blasting effect. Conclusions: Indirect ophthalmoscope laser in 810-nm diode laser with large-spot alone or combined with systemic chemotherapy may be effective treatment for retinoblastoma in earlier than stage C of international classification. It is suitable for large and multiple retinoblastoma.(Chin J Ophthalmol, 2016, 52: 745-748).

Abstract
OBJECTIVE To evaluate the economic effect of Measles, Mumps and Rubella Combined Attenuated Live Vaccine (MMR) under different two-dose vaccination programs. METHODS A hypothetical birth cohort of 750 000 infants over their lifetime, was followed up from birth through death in Zhejiang province. The current MMR vaccination strategie would include three different ones: 1) Childlern were vaccinated with Measles-Rubella Combined Attenuated Live Vaccine and MMR, respectively at the age of 8 months and 18 months. 2) Children receive MMR at 8 months and 18 months, 3) Strategy 1 plus an additional vaccination of MMR at 4 years of age. Incremental cost-effectiveness ratio (ICER), incremental cost-benefit ratio (ICBR) and incremental net benefit (INB) were applied to calculate the health economic difference for Strategy 2 and Strategy 3 as compared to Strategy 1. Univariate sensitivity analysis was used to assess the robustness of results with main parameters, including the rate of immunization coverage, effectiveness of the vaccines, incidence and burdens of the related diseases, cost of vaccines and the vaccination program itself. RESULTS ICER, ICBR and INB for Strategy 2 and Strategy 3 appeared as 2 012.51∶1 RMB Yuan per case and 4 238.72∶1 RMB Yuan per case, 1∶3.14 and 1∶1.58, 21 277 800 RMB Yuan and 9 276 500 RMB Yuan, respectively. Only slight changes (<20%) were found under the univariate sensitivity analysis, with varied values on main parameters. CONCLUSION Based on the current national immunization program, infants vaccinated with MMR at 8 months of age, generated more health economic effects than the Strategy 3.

Abstract
Abstract
Background: Formerly, apoptosis was considered the only form of regulated cell death and evading apoptosis was considered a hallmark of cancer. However, in recent years, necroptosis has been discovered as a new pathway of regulated cell death. Animal studies revealed very critical roles of necroptosis in many human inflammatory diseases and tumors. Early studies examining apoptosis by using TdT-mediated dUTP nick end labelling (TUNEL) assays cannot distinguish between apoptotic and necroptotic cells. Bax, which is a pro-apoptoic member of Bcl-2 family, is essential for mitochondrion-mediated apoptosis. Very recently, mixed lineage kinase domain-like (MLKL) is identified to be necessary for the execution of necroptosis. Cyclooxygenase (Cox), including Cox-1 and Cox-2, are the key enzymes responsible for the conversion of arachidonic acid to prostaglandins, which are important mediators of human physiology and pathophysiology, particularly inflammation. High expression of Cox-2 plays a critical role in the development of colorectal neoplasms. No study has examined how necroptosis biomarker (i.e. MLKL) and pro-apoptosis biomarker (i.e. Bax) are related to inflammation biomarker (Cox-2), TUNEL and cell proliferation biomarker (Ki-67). Methods: In our ongoing randomized trial (R01CA149633) “Personalized Prevention of Colorectal Cancer Trial (PPCCT)” conducted among colorectal polyp patients or those at high risk of colorectal cancer, we newly investigated the relationships between markers in these pathways using rectal biopsies (n = 110) collected prior to intervention in the trial. The formalin-fixed and paraffin-embedded tissue from colorectal biopsy was serially sectioned, and three levels of the serial sections spaced 50 μm apart. were mounted on to one slide for each tissue block. The protein expression levels of Cox-2, Bax, pMLKL, and Ki-67 were detected immunohistochemically following EnVision+ System-HRP (DAB) rabbit or mouse kit (DAKO). Apoptotic cells in situ were detected with DeadEnd™ Colorimetric TUNEL System (Promega). Results: Cox-2 expression in both epithelium and stroma had strong positive correlation with Bax expression in the same zone (p-trend = 0.00186 and 0.00004, respectively) but was not significantly correlated with pMLKL. The positive associations were stronger in the upper zone than the bottom of the crypts. The upper zone also showed more TUNEL positive cells than the bottom zone, and had significant positive correlation with pMLKL intensity (r = 0.458, p = 0.005). Bax expression was not significantly related to MLKL expression. Conclusion: Cox-2 expression in non-tumoral colonic tissue may activate apoptotic pathway through Bax upregulation, but is not correlated with necroptotic pathway marker MLKL. In the epithelium, the necroptotic pathway may be more common in the upper zone of colonic cryps than the bottom zone,and may more strongly contribute to TUNEL than apoptosis pathway.

Abstract
We consider dipolar excitations propagating via dipole-induced exchange among immobile molecules randomly spaced in a lattice. The character of the propagation is determined by long-range hops (Levy flights). We analyze the eigenenergy spectra and the multifractal structure of the wave functions. In 1D and 2D, all states are localized, although in 2D the localization length can be extremely large leading to an effective localization-delocalization crossover in realistic systems. In 3D, all eigenstates are extended but not always ergodic, and we identify the energy intervals of ergodic and nonergodic states. The reduction of the lattice filling induces an ergodic to nonergodic transition, and the excitations are mostly nonergodic at low filling.

Abstract
West Nile virus (WNV) infection results in a diverse spectrum of outcomes, and host genetics are likely to influence susceptibility to neuroinvasive disease (West Nile neuroinvasive disease (WNND)). We performed whole-exome sequencing of 44 individuals with WNND and identified alleles associated with severe disease by variant filtration in cases, kernel association testing in cases and controls and single-nucleotide polymorphism (SNP) imputation into a larger cohort of WNND cases and seropositive controls followed by genome-wide association analysis. Variant filtration prioritized genes based on the enrichment of otherwise rare variants, but did not unambiguously implicate variants shared by a majority of cases. Kernel association demonstrated enrichment for risk and protective alleles in the human leukocyte antigen (HLA)-A and HLA-DQB1 loci that have well understood roles in antiviral immunity. Two loci, HERC5 and an intergenic region between CD83 and JARID2, were implicated by multiple imputed SNPs and exceeded genome-wide significance in a discovery cohort (n=862). SNPs at two additional loci, TFCP2L1 and CACNA1H, achieved genome-wide significance after association testing of directly genotyped and imputed SNPs in a discovery cohort (n=862) and a separate replication cohort (n=1387). The context of these loci suggests that immunoregulatory, ion channel and endothelial barrier functions may be important elements of the host response to WNV.

Abstract
BACKGROUND It is well established that the activation of the renin-angiotensin system (RAS) and the oxidative stress caused by hyperglycemia are major mediators of the development and progression of diabetic nephropathy (DN). Vitamin D may be important in maintaining podocyte health, preventing epithelial-to-mesenchymal transformation, and suppressing renin gene expression and inflammation, but its mechanism requires clarification. This study evaluated the specific mechanism of vitamin D to DN improvement. METHODS We induced a rat model of diabetes with an intraperitoneal injection of streptozotocin (60 mg/kg). The streptozotocin-induced diabetic rats were fed normal chow for about 2 months to induce the DN model. The DN rats were then treated with irbesartan and/or calcitriol, administered intragastrically about 1 month. RESULTS The rats displayed the early characteristics of DN, including increased microalbuminuria, obvious hypertrophic kidney, and a markedly increased kidney weight/bodyweight ratio. Vitamin D inhibited the compensatory increase in renin expression. Malondialdehyde, which reflects oxidative stress levels, was elevated in the DN group rats and their antioxidant capacity was significantly reduced. The irbesartan and calcitriol interventions markedly improved the renal pathology and pathophysiological changes. Irbesartan combined with vitamin D (calcitriol) more effectively ameliorated DN than irbesartan alone. CONCLUSIONS Vitamin D combined with angiotensin II type 1 receptor blockers exerts a synergistic effect on the treatment of DN, not only by inhibiting renin but also by reducing oxidative stress and increasing the renal antioxidant capacity.

Abstract
After unprecedented development of organic-inorganic lead halide perovskite solar cells over the past few years, one of the biggest barriers towards their commercialization is the stability of the perovskite material. It is thus important to understand the interaction between the perovskite material and oxygen and/or humidity and the associated degradation process in order to improve device and encapsulation design for better durability. Here we characterize the dynamic aging process in vapour-assisted deposited (VASP) CH3NH3PbBr3 perovskite thin films using advanced optical techniques, such as time-resolved photoluminescence and fluorescence lifetime imaging microscopy (FLIM). Our investigation reveals that the perovskite grains grow spontaneously and the larger grains are formed at room temperature in the presence of moisture and oxygen. This crystallization process leads to a higher density of defects and a shorter carrier lifetime, specifically in the larger grains. Excitation-intensity-dependent steady-state photoluminescence shows both N2 stored and aged perovskite exhibit a super-linear increase of photoluminescence intensity with increasing excitation intensity; and the larger slope in aged sample suggests a larger density of defects is generated, consistent with time-resolved PL measurements.

Abstract
We report the first measurement of the target single-spin asymmetry, A(y), in quasielastic scattering from the inclusive reaction (3)He(↑)(e,e') on a (3)He gas target polarized normal to the lepton scattering plane. Assuming time-reversal invariance, this asymmetry is strictly zero for one-photon exchange. A nonzero A(y) can arise from the interference between the one- and two-photon exchange processes which is sensitive to the details of the substructure of the nucleon. An experiment recently completed at Jefferson Lab yielded asymmetries with high statistical precision at Q(2)=0.13, 0.46, and 0.97 GeV(2). These measurements demonstrate, for the first time, that the (3)He asymmetry is clearly nonzero and negative at the 4σ-9σ level. Using measured proton-to-(3)He cross-section ratios and the effective polarization approximation, neutron asymmetries of -(1-3)% were obtained. The neutron asymmetry at high Q(2) is related to moments of the generalized parton distributions (GPDs). Our measured neutron asymmetry at Q(2)=0.97 GeV(2) agrees well with a prediction based on two-photon exchange using a GPD model and thus provides a new, independent constraint on these distributions.

Abstract
BACKGROUND The NLR family, pyrin domain-containing 3 (NLRP3) inflammasome plays a key role in intracerebral hemorrhage (ICH)-induced inflammatory injury, and the purinergic 2X7 receptor (P2X7R) is upstream of NLRP3 activation. This study aimed to investigate how P2X7R functions in ICH-induced inflammatory injury and how the receptor interacts with the NLRP3 inflammasome. METHODS Rats were treated with P2X7R small interfering RNA (siRNA) 24 h before undergoing collagenase-induced ICH. A selective P2X7R inhibitor (blue brilliant G, BBG) or a peroxynitrite (ONOO(-)) decomposition catalyst (5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrinato iron(III) [FeTPPS]) was injected 30 min after ICH. Brain water content, hemorrhagic lesion volume, and neurological deficits were evaluated, and western blot, immunofluorescence, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) were carried out. RESULTS Striatal P2X7R and NLRP3 inflammasomes were activated after ICH. Gene silencing of P2X7R suppressed NLRP3 inflammasome activation and interleukin (IL)-1β/IL-18 release and significantly ameliorated brain edema and neurological deficits. Additionally, enhanced NADPH oxidase 2 (NOX2, gp91(phox)) and inducible nitric oxide synthase (iNOS), as well as their cytotoxic product (ONOO(-)) were markedly attenuated by BBG treatment following ICH. This was accompanied by downregulations of the inflammasome components, IL-1β/IL-18 and myeloperoxidase (MPO, a neutrophil marker). Most importantly, inflammasome activation and IL-1β/IL-18 release were significantly inhibited by ONOO(-) decomposition with FeTPPS. CONCLUSIONS Our findings implicate that P2X7R exacerbated inflammatory progression and brain damage in ICH rats possibly via NLRP3 inflammasome-dependent IL-1β/IL-18 release and neutrophil infiltration. ONOO(-), a potential downstream signaling molecule of P2X7R, may play a critical role in triggering NLRP3 inflammasome activation.

Abstract
Abstract
Background: High calcium or high magnesium consumption has been linked to reduced risks of colorectal adenoma and cancer. However, results are not consistent. In the Tennessee Colorectal Polyp Study (TCPS), the Calcium Polyp Prevention Study (a large-scale randomized trial), we found that high intake of supplemental calcium or total calcium was related to a reduced risk of colorectal adenoma or adenoma recurrence only among those with calcium/magnesium intake ratio below 2.8 or 2.6. This effect modification by the calcium/magnesium ratio cannot solely be attributed to the dietary intake in calcium or magnesium. Furthermore, we found in the TCPS that calcium/magnesium intake ratio significantly interacted with Thr1482Ile polymorphism (rs8042919, GàA) in the TRPM7 gene, in relation to both adenomas and hyperplastic polyps. The TRPM7 gene is involved in magnesium and calcium re(absorption) and homeostasis. Compared to those with the GG genotype, we found that people who carry A allele(s) were at 60% and 85% increased risks of adenoma and hyperplastic polyp, respectively, if they also consumed diets with calcium/magnesium intake ratio >2.8; and the corresponding risks increased by 345% and 1500% among those with the AA genotype. The risk was not increased among those who carried the A allele(s) if they consumed diets low in calcium/magnesium ratio (<2.8).
Objectives: 1) Test the hypothesis whether reducing the calcium/magnesium through magnesium supplementation affects biomarkers related to colorectal carcinogenesis in rectal tissues; and 2) Test whether the effect differs by TRPM7 genotype.
Methods: Personalized Prevention of Colorectal Cancer Trial (PPCCT, R01CA149633) is an ongoing double-blind, randomized trial of 12 week personalized magnesium supplementation. 288 participants with high calcium/magnesium intake ratio and at high risk of colorectal cancer are being recruited. The uniqueness of the trial includes 1) only target participants with a high calcium/magnesium ratio through nutritional screening using multiple 24-hour dietary recalls; 2) personalized doses are based on and used to reduce the current calcium/magnesium intake ratios; and finally, 3) the participants are also randomized by the TRPM7 genotype.
Results: As of July 20, 2014, we have enrolled at least 170 participants. We have conducted immunohistochemical assays to measure expressions of carcinogenesis biomarkers, including apoptosis, cell proliferation, COX2 and TRPM7, in normal rectal tissues collected at baseline and the end of the intervention for 40 participants who first completed the trial. We are also assaying lipid profile and other novel biomarkers, including DNA methylation, and microbial markers. We have obtained some very promising preliminary findings. We will report updated findings in the presentation.
Conclusions: The results from our study may ultimately help to develop personalized strategies to prevent colorectal cancer.
