Public Health 2016; 141:153-162. [PMID: 27931992 DOI: 10.1016/j.puhe.2016.09.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2016] [Revised: 08/31/2016] [Accepted: 09/06/2016] [Indexed: 12/26/2022]
Abstract
OBJECTIVES To explore the attitudes of primary healthcare workers, including township public health workers (TPHWs) and village doctors (ViDs), towards web-based training on basic public health services (BPHS) and to examine the factors influencing their attitudes. STUDY DESIGN Cross-sectional study. METHODS Questionnaires addressing training status, needs, and attitudes towards web-based public health training were administered to 2768 primary healthcare workers from May to September 2013. Multivariate logistic regression models were used to identify the factors that were significantly associated with a positive attitude towards web-based public health training. RESULTS Among the 2768 participants, 90.6% of the TPHWs and 86.9% of the ViDs expressed a positive attitude towards web-based BPHS training. TPHWs who had a positive attitude towards previous public health training (odds ratio [OR] = 2.75, 95% confidence interval [CI] = 1.28-5.93) and better computer skills (OR = 2.59, 95% CI = 1.03-6.48) were more likely to adopt web-based training on BPHS, as were ViDs who had better computer skills (OR = 2.54, 95% CI = 1.58-4.11) and better Internet speeds (neutral: OR = 2.81, 95% CI = 1.58-5.01; satisfied: OR = 2.53, 95% CI = 1.28-5.01). TPHWs who tended to read papers (OR = 0.24, 95% CI = 0.11-0.50) and were aged 50 years or older (OR = 0.34, 95% CI = 0.14-0.87), as were ViDs who tended to read papers (OR = 0.48, 95% CI = 0.29-0.77), expressed a more negative attitude towards web-based BPHS training. CONCLUSIONS The findings indicated that most primary healthcare workers have a positive attitude towards web-based BPHS training. More priority measures, such as conducting computer training, improving Internet quality and integrating mobile technology, are recommended and will further improve the implementation of web-based public health training programs.

Abstract
The extracellular matrix (ECM) is the major macromolecule in skeletal muscle, which affects meat quality greatly. The remodeling of the ECM is mainly regulated by matrix metalloproteinases (MMPs). The expression patterns of MMP-1, -2, and -8 in longissimus dorsi muscle were explored using quantitative real-time polymerase chain reaction. The results show that the expression of MMP-1, -2, and -8 decreased significantly from 135 days of pregnancy to postnatal 30 months. While the expression of MMP-1, -2, and -8 showed no significant relationships with intramuscular fat contents, MMP-1 and -2 showed significant negative correlations with the shearing force of the longissimus dorsi muscle in cattle. The expression of MMP-1 also showed a significant negative correlation with cooking loss and a positive correlation with water holding capacity. The expression levels of MMP-1 and -2 were usually higher in fat than in skeletal muscle tissue. The expression of MMP-8 was significantly higher in the mammary fat pad and the longissimus dorsi muscle than in all other tissues. This study indicates that the remodeling of the ECM has important effects both on the development of postnatal skeletal muscle and on meat quality.

Abstract
To investigate the expression of interleukin-24 (IL-24) in the children with acute leukemia (AL) and its effect on the apoptosis of bone marrow mononuclear cells (BMMNCs) in vitro. Four groups were assessed: acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), non-leukemia, and healthy groups, 20 children in each group. ELISA was used to measure IL-24 serum level. The bone marrow was taken from patients and controls. BMMNCs were isolated and the DNA was analyzed by glucose electrophoresis. Flow cytometry was used to determine BMMNC apoptosis. The serum level of IL-24 in the ALL and AML groups were significantly higher than in the other two groups. There was no statistical difference between ALL and AML groups, either between non-leukemia and healthy groups. BMMNCs were exposed to IL-24 for 48 h, and the apoptotic rate of the group treated with 50 ng/ml IL-24 was obviously higher than that of control group (0 ng/mL). The serum IL-24 level of AL children decreased comparing to non-leukemia and healthy children, indicating that IL-24 can induce BMMNCs apoptosis of AL children in vitro.

Abstract
APC is a tumor suppressor gene that is involved in the processes of cell migration and adhesion, transcriptional activation, and apoptosis. The goal of this study was to evaluate the contribution of the APC rs383830 polymorphism to coronary heart disease (CHD) in Han Chinese. A total of 783 patients with CHD and 737 controls were tested in the current association study. Although our study did not identify an association between the APC rs383830 polymorphism and CHD, a breakdown analysis by gender indicated there was a significant contribution of the rs383830 T allele to the risk of CHD in males (P = 0.046, odds ratio = 1.267, 95% confidence interval = 1.004-1.598). In conclusion, our study suggested a male-specific association of the APC rs383830 polymorphism with CHD.

Abstract
We explored the associations of INSR and mTOR, 2 key genes in the insulin signaling pathway, and the susceptibility to type 2 diabetes mellitus and diabetic nephropathy. Three single-nucleotide polymorphisms (SNPs) (rs1799817, rs1051690, and rs2059806) in INSR and 3 SNPs (rs7211818, rs7212142, and rs9674559) in mTOR were genotyped using the Sequenom MassARRAY iPLEX platform in 89 type 2 diabetes patients without diabetic nephropathy, 134 type 2 diabetes patients with diabetic nephropathy, and 120 healthy control subjects. Statistical analysis based on unconditional logistic regression was carried out to determine the odds ratio (OR) and 95% confidence interval (95%CI) for each SNP. Combination analyses between rs2059806 and rs7212142 were also performed using the X(2) test and logistic regression. Among these 6 SNPs, 4 (rs1799817, rs1051690, rs7211818, and rs9674559) showed no association with type 2 diabetes mellitus or diabetic nephropathy. However, rs2059806 in INSR was associated with both type 2 diabetes mellitus (P = 0.033) and type 2 diabetic nephropathy (P = 0.018). The rs7212142 polymorphism in mTOR was associated with type 2 diabetic nephropathy (P = 0.010, OR = 0.501, 95%CI = 0.288- 0.871), but showed no relationship with type 2 diabetes mellitus. Combination analysis revealed that rs2059806 and rs7212142 had a combined effect on susceptibility to type 2 diabetes mellitus and diabetic nephropathy. Our results suggest that both INSR and mTOR play a role in the predisposition of the Han Chinese population to type 2 diabetic nephropathy, but the genetic predisposition may show some differences.

Abstract
The common fig (Ficus carica) is one of the earliest plants domesticated by humans. It has been cultivated in China ever since the early seventh century. Fig fruit is an important traditional Chinese medicine and a fine health food, featuring a unique flavor and rich nutrients. In addition to its great medicinal values, its abundant availability in the Xinjiang province of China has made the fig one of the most popular fruits in the country. One of the major diseases that affect figs is the fig mosaic disease (FMD) (1,4), which was reported in China in 1935 (3). A causal agent of this disease is associated with the Fig mosaic virus (FMV), a negative-strand RNA virus with six RNA segments (2). In 2013, and later during a survey in 2014, fig plants in several orchards in Xinjiang displayed symptoms of a virus-like disease, which was characterized as FMD. These symptoms included chlorotic clearing as well as banding of leaf veins along with various patterns of discoloration, severely distorted leaves, and deformed fruits. Total RNA extracts (TRIzol reagent, Ambion) from 18 symptomatic and four asymptomatic leaf samples were subjected to reverse reaction (RT) assays using M-MLV reverse transcriptase (Promega, Fitchburg, WI) with primer FMV-GP-R (TATTACCTGGATCAACGCAG). PCR analysis of the synthesized cDNA was performed using FMV-specific primers FMV-GP-F (ACTTGCAAAGGCAGATGATA) and FMV-GP-R. Amplicons of 706 bp produced by RT-PCR assays were obtained from most (15 out of 18) of the symptomatic samples; however, none was obtained from the four asymptomatic leaves. The purified amplicons were cloned and sequenced. BLAST analysis of these sequences revealed more than 94% nucleotide identity with glycoprotein precursor (GP) genes of an FMV-Serbia isolate (SB1). One sequence was deposited in NCBI databases, and one sequence was submitted to GenBank (Accession No. KM034915). RNA segments 2 to 6 of FMV were also amplified by RT-PCR and sequenced. These sequences showed 94 to 96% identity with FMV sequences deposited in the NCBI databases. The collected samples were further detected by Northern-blot hybridization with a digoxigenin-labeled RNA probe, which targets the RNA1 genome of the FMV. The result was in line with RT-PCR detection. To our knowledge, this is the first report of FMV in fig trees in China. Considering the economic importance of fig plants and the noxious nature of FMV, this virus poses a great threat to the economy of the fig industry of Xinjiang. Thus, it is important to develop immediate effective quarantine and management of this virus to reduce any further predictable loss. References: (1) T. Elbeaino et al. J. Gen. Virol. 90:1281, 2009.

Abstract
The red imported fire ant (RIFA) Solenopsis invicta Buren causes severe damage to humans and animals as well as the environment. Chemical treatment is the main strategy of RIFA management, which also is potentially toxic to the environment. Plant essential oils (EOs) are considered as potential substance that can be used to control insects. This study aimed to identify the chemical composition of camphor EO and investigate the insecticidal activity on RIFAs. The chemical composition of the EO was analyzed by gas chromatography/mass spectrometry and gas chromatography with flame ionization detection. Results revealed that 36.61% camphor and 30.05% cineole were the major components. The insecticidal activity of camphor EO was assessed against RIFA workers by conducting two different bioassays: fumigant toxicity and repellence. Fumigant toxicity assay results showed that the lethal dose (LC50) of the EO at 24 h was 1.67 and 4.28 μg/ml for minor and major workers, respectively; knockdown time (KT50) was 10.82 and 14.73 h. At 2.55 μg/ml, the highest average mortality of the ants was 84.89% after 72 h. Camphor EO exhibited fumigant toxicity against minor and major workers as indicated by the effects on attacking, feeding, and climbing behaviors. This EO was also strongly repellent to the two size workers of the colony as observed in their behavior against Tenebrio molitor treated with 5 µl EO. The fumigant toxicity and repellence of camphor EO against RIFA indicated that this substance could be a potential alternative for the development of eco-friendly products used to control pests.

Abstract
A 2D coordination polymer prepared with bulky diethylformamide solvates exhibits channels which allow dipyridyl bridging ligands to diffuse into the crystal lattice. The absorbed dipyridyls thread through the pores of one layer and substitute the surface diethylformamide molecules on the neighboring layers to stitch alternate layers to form flexible interpenetrated metal-orgaic frameworks. The threading process also results in exchange of the bulky diethylformamide solvates for aqua to minimize congestion and, more strikingly, forces the slippage of two-dimensional layers, while still maintaining crystallinity.

Abstract
Unveiling the genetic architecture of grain yield and yield-related traits is useful for guiding the genetic improvement of crop plants. Kernel row number (KRN) per ear is an important yield component, which directly affects the grain yield of maize. In this study, we constructed a set of 130 chromosome segment substitution lines (CSSLs), using Nongxi531 as the donor parent and H21 as recipient parent, by continuous backcrossing and selfing. In total, 11 quantitative trait loci (QTL) were detected for KRN by stepwise regression under 3 environmental settings, with 9.87-19.44% phenotypic variation being explained by a single QTL. All 11 QTL were also detected by single-factor ANOVA across the 3 environments tested. Of these 11 QTL, 4 were identified across more than 2 environments, indicating that they are authentically expressed under different environments to control the formation and development of KRN in female maize inflorescences. The CSSLs harbored a greater number of favorable alleles for KRN compared to the H21 line, and could be employed as improved H21 lines in maize breeding programs.

Abstract
During March through July 2012, 10 to 15% of the Vitis vinifera cultivars Thompson Seedless and Anab-e-Shahi exhibited yellow leaf spots and flecks, shortened internodes, and tiny yellow leaves in vineyards of the Bijapur, Doddaballapur, and Kolar districts of Karnataka State, India. These are the major grapevine cultivation regions in India. Samples were collected from four different plants from each district (12 samples in total) and RNA was extracted using 2X CTAB buffer (1). Presence of Grapevine yellow speckle viroid1 (GYSVd-1, genus Apscaviroid) was tested by reverse transcription (RT)-PCR with primer pair PBCVd100C/194H (4) for the amplification of a 220-bp region of the genome. In agarose gel electrophoresis, five samples showed amplicons of the expected size. These amplicons were cloned and sequenced. BLAST analysis confirmed the presence of GYSVd-1. Based on this data, the full-length genome of GYSVd-1 was amplified by RT-PCR using primer pair 341M (5'-CACTCGCGGGGCGCGTTGGA-3') and 342P (5'-CAATCCCCGGAACCCCCGCT-3') and the amplicons were cloned and sequenced. Sequence analysis revealed two sequence variants namely Kar-1 (GenBank Accession No. AB742222) and Kar-2 (AB742223) with 98% and 99% identity to GYSVd-1 variants IXc (X87913) and II (X87906), respectively. GYSVd-1 variants Kar-1 and Kar-2 clustered in two distinct phylogenetic sub-clades. All 12 samples also tested positive for Hop stunt viroid (HpSVd, genus Hostuviroid) in two separate sets of RT-PCR using HSV-78P (5'-AACCCGGGGCAACTCTTCTC-3') and HSV-83M (5'-AACCCGGGGCTCCTTTCTCA-3'); and HSV-7P (5'-AATTCTCGAGTTGCCGC-3') and HSV-220M (5'-CGAACCGAGAGGTGATGCCA-3'), with the expected size of 303 and 213 bp, respectively (3). Sequence analysis of the amplicons confirmed the presence of HpSVd. Alignment of HpSVd nucleotide sequences obtained from the 12 samples showed the presence of a single type of sequence variant, namely Ind-2 (AB742225). BLAST analysis showed 99% sequence identity of Ind-2 with a HpSVd variant isolated from a 100-year-old grapevine in China. All 12 grapevine samples were also tested for the presence of Australian grapevine viroid (AGVd, genus Apscaviroid), Grapevine yellow speckle viroid 2 (GYSVd 2, genus Apscaviroid), and Citrus exocortis viroid (CEVd, genus Pospiviroid) by RT-PCR as described previously (2). None of the samples showed any positives. Northern blot assay using appropriate digoxigenin-labeled riboprobes performed as described previously (2) further confirmed RT-PCR results. Positive controls for RT-PCR and Northern blot were obtained from viroid-infected grapevines maintained in the greenhouse. GYSVd-1 and HpSVd were detected in symptomatic and symptomless plants. Hence, the symptoms observed in the vineyard cannot be attributed to viroid infection. More work is needed to identify the causal agent(s) of the decline of Thompson Seedless and Anab-e-Shadi cultivars. References: (1) C. R. Adkar-Purushothama et al. Plant Dis. 97:149, 2013. (2) D.

Abstract
OBJECTIVES This study was to explore the independent influence of menopause on cardiovascular disease (CVD) and its risk factors in rural Chinese females. STUDY DESIGN This cross-sectional population-based study enrolled 2245 premenopausal and 2498 postmenopausal women aged 40-59 years in Fangshan district, Beijing, China. Data was collected by face-to-face interview, physical examination and biochemical examination during 2009 and 2010. General liner models were employed to calculate age-adjusted means of cardiovascular risk factors (CRFs). The comparisons of CVD and it risk factors according to menopausal status, and calculation of adjusted odds ratios/coefficients and their 95% confidence intervals for the associations of quartiles of elapsed time since menopause and age at menopause with CVD and its risk factors was performed by multivariate logistic/liner regression models separately. RESULTS After adjustment for age and other confounders, no statistically significant association of menopause with CVD was observed in our participants; however, dyslipidemia prevalence and levels of waist-to-hip ratio, triglycerides, total cholesterol and low-density lipoprotein cholesterol were presented higher in postmenopausal group, compared to the premenopausal one (P<0.05). Compared to women who had been menopausal for less than1 year, those with the elapsed time since menopause of 2-3 years had higher CHD prevalence, higher triglycerides level and lower high-density lipoprotein cholesterol level (P<0.05). CONCLUSIONS Postmenopausal women in rural China had worse CRFs profile than the premenopausal ones, which implied menopause might aggravate the CRFs epidemic beyond effects of aging, and would increase the CVD burden during and after their middle ages.

Abstract
The novel allele human leukocyte antigen (HLA)-A*11:01: 10 differs from HLA-A*11:01:10 by a synonymous nucleotide exchange at codon 146 in exon 2 (G/A). Here, we describe the identification of the novel allele HLA-A*11:01:10, which has been detected in a registered donor of the China Marrow Donor Program. The complete HLA typing results were as follows: A*02:01, *11:01:10; B*15:11, *15:18; C*03:03, *08:01; DRB1*08:02, *15:01.

Abstract
The primary function of the human leukocyte antigen (HLA) system is to regulate the immune response. Because of its important role in the immune response and its high degree of polymorphism, the HLA system is associated with many diseases. We examined the polymorphisms of HLA-A, B and DRB1 alleles in 100 unrelated patients with lung carcinoma and in 438 unrelated normal controls of Han nationality from North China, using sequence-based typing and PCR with sequence-specific primers. We found that the frequencies of HLA-A*0201, A*2601, B*1518, B*3802, DRB1*0401, DRB1*0402, and DRB1*1201 were higher in the lung carcinoma group than in the normal control group. The P values were 0.035, 0.040, 0.001, 0.017, 0.014, 0.004, and 0.019, respectively, and the odds ratio values were 1.052, 3.513, 4.047, 3.054, 4.237, 19.397, and 2.128, respectively. The frequency of HLA-DRB1*1302 was lower in the lung carcinoma group than in the normal control group (P = 0.046, odds ratio = 0.168). We concluded that patients with lung cancer and healthy controls of Han nationality from North China differ in the frequencies of various HLA alleles.

Abstract
OBJECTIVE To explore factors throughout the lifespan that influence cognition in midlife to late life. METHODS We conducted a retrospective birth cohort study of 2,062 individuals born during 1921-1954 in Beijing, China. In 2003-2005, birth records were abstracted, and participants then 50-82 years old received standardized examinations for health, cognition, and socio-environmental measures. Using cumulative logit models, we assessed adjusted relative effects of prenatal, early life, and adult factors on mid- to late-life cognition. RESULTS Most prenatal factors were associated with mid- to late-life cognition in the unadjusted models. However, when childhood and adult factors were sequentially added to the models, the impact of prenatal factors showed successive attenuation in effect size, and became insignificant. In contrast, early life factors remained significantly associated with mid- to late-life cognition even after full life-course adjustments. Specifically, those whose fathers had laborer vs professional occupations (odds ratio [OR](Laborer) 1.74; 95% confidence interval [CI]: 1.25-2.42) had poorer cognitive outcomes, while individuals who drank milk daily in childhood (OR 0.65; 95% CI: 0.54-0.80), had more years of education (OR(10-12 years) 0.60; 95% CI: 0.45-0.81; OR(13+ yrs) 0.29; 95% CI: 0.23-0.38), and were taller adults (OR(height > or = SD) 0.65; 95% CI: 0.49-0.86) had better cognition. The high prenatal risk infants had similar patterns with a trend toward a stronger association between cognition and socioenvironmental factors. CONCLUSION Mid- to late-life cognition is influenced by factors over the entire lifespan with the greatest impact coming from early life exposures. Nutrition, education, social, and family environment in early life may have a long-term impact on cognition in developing countries.

Abstract
Cationic polymers with low cytotoxicity and high transfection efficiency have attracted considerable attention as nonviral carriers for gene delivery. Herein, well-defined and star-shaped CDPD consisting of beta-CD cores and P(DMAEMA) arms, and CDPDPE consisting of CDPD and P(PEGEEMA) end blocks (where CD = cyclodextrin, P(DMAEMA) = poly(2-(dimethylamino)ethyl methacrylate), P(PEGEEMA) = poly(poly(ethylene glycol)ethyl ether methacrylate)) for gene delivery were prepared via atom transfer radical polymerization (ATRP) from the bromoisobutyryl-terminated beta-CD core. The CDPD and CDPDPE exhibit good ability to condense plasmid DNA (pDNA) into 100-200 nm size nanoparticles with positive zeta potentials of 25-40 mV at nitrogen/phosphate (N/P) ratios of 10 or higher. CDPD and CDPDPE exhibit much lower cytotoxicity and higher gene transfection efficiency than high molecular weight P(DMAEMA) homopolymers. A comparison of the transfection efficiencies between CDPD and P(DMAEMA) homopolymer indicates that the unique star-shaped architecture involving the CD core can enhance the gene transfection efficiency. In addition to reducing cytotoxicity, the introduction of a biocompatible P(PEGEEMA) end block to the P(DMAEMA) arms in CDPDPE can further enhance the gene transfection efficiency.

Abstract
We observe an obvious anomalous line shape of the e;{+}e;{-}--> hadrons total cross sections in the energy region between 3.700 and 3.872 GeV. It is inconsistent with the explanation for only one simple psi(3770) resonance with a statistical significance of 7sigma. The anomalous line shape may be explained by two possible enhancements of the inclusive hadron production near the center-of-mass energies of 3.764 and 3.779 GeV, indicating that either there is likely a new structure in addition to the psi(3770) resonance around 3.773 GeV, or there are some physics effects reflecting the DD[over ] production dynamics.

Abstract
The plasma membrane of mammalian cells can be transiently permeablized by optical means and exogenous materials or genes can be introduced into the cytoplasm of living cells. Until now, few mechanisms were exploited for the manipulation: laser is directly and tightly focused on the cells for optoinjection, laser-induced stress waves, photochemical internalization, and irradiation of selective cell targeting with light-absorbing particles. During the past few years, extensive progress and numerous breakthroughs have been made in this area of research. This review covers four different laser-assisted transfection techniques and their advantages and disadvantages. Universality towards various cell lines is possibly the main advantage of laser-assisted optoporation in comparison with presently existing methods of cell transfection.

Abstract
Using psi(2S) --> pi(+)pi(-) J/psi events in a sample of 14.0 x 10(6) psi(2S) decays collected with the BES-II detector, a search for the decay of the J/psi to invisible final states is performed. No signal is found, and an upper limit at the 90% confidence level is determined to be 1.2 x 10(-2) for the ratio B(J/psi --> invisible)/B(J/psi-->mu(+)mu(-)). This is the first search for J/psi decays to invisible final states.

Abstract
The decays of J/psi --> etaphif(0)(980)[eta --> gammagamma, phi --> K(+) K(-), f(0)(980) --> pi(+)pi(-)] are analyzed using a sample of 5.8 x 10(7) J/psi events collected with the BESII detector at the Beijing Electron-Positron Collider. A structure at around 2.18 GeV/c(2) with about 5 sigma significance is observed in the phif(0)(980) invariant mass spectrum. A fit with a Breit-Wigner function gives the peak mass and width of m = 2.186+/-0.010(stat)+/-0.006(syst) GeV/c(2) and Gamma = 0.065+/-0.023(stat)+/-0.017(syst) GeV/c(2), respectively, which are consistent with those of Y(2175), observed by the BABAR Collaboration in the initial-state radiation process e(+)e(-) --> gamma(ISR) phif(0)(980). The production branching ratio is determined to be Br(J/psi --> etaY(2175))Br(Y(2175)- -> phif(0)(980))Br(f(0)(980) --> pi(+)pi(-)) = [3.23+/-0.75(stat)+/-0.73(syst)] x 10(-4), assuming that the Y(2175) is a 1(--) state.
