Abstract
OBJECTIVE To evaluate a new prenatal diagnosis model of chromosomal abnormalities and nine microdeletion syndromes by using both traditional karyotyping and a newly-developed rapid prenatal diagnosis technology, BACs-on-Beads (BoBs) technique. METHODS From June 2012 to December 2014, 807 pregnant women with high risk after screening or with other indicators, were performed amniocentesis. Traditional karyotyping and BoBs were employed simultaneously for prenatal diagnosis. RESULTS Thirty-two cases with chromosome aneupoidies were successfully detected both by BoBs and karyotyping, including 18 cases of trisomy 21, 6 cases of trisomy 18, 1 case of trisomy 13, and 7 cases with sex chromosome abnormality. All 8 fetuses with chromosome structural abnormalities detected by karyotyping were missed by BoBs; while BoBs contributed more in detection of five microdeletion syndrome cases, including 3 cases of DiGeorge syndromes (two with microduplication and one with microdeletion), one case of Miller-Dieker syndrome, and one case of Wolf-Hirschhorn syndrome. CONCLUSION Combined use of traditional karyotyping and BoBs, is a rapid and effective prenatal diagnosis model that may enlarge our horizon on chromosomal diseases and should be widely used in future clinical service.

Abstract
Brucellosis is an occupational disease affecting workers in butcher shops, the milking and dairy product industry, causing more than 500 000 new cases around the world. As a national statutory B infectious disease in China, morbidity of brucellosis is rapidly increasing in recent years. We report an occupational outbreak of brucellosis infection in a pharmaceutical factory. Exposure was a result of manual operation in the process line, close contact with sheep placentas, insufficient disinfection and repeated using of protective suits and infected by aerosol dissemination. Improved preventive methods, appropriate public health measures and spread of health education would be helpful to prevent the occupational outbreak of brucellosis in future.

Abstract
Primary biliary cholangitis (PBC), hitherto called primary biliary cirrhosis, is a cholestatic liver disease of unclear aetiology with autoimmune features. Accumulating evidence revealed that γδ T cells were involved in the development of autoimmune diseases. As one of γδ T cells subsets, however, the role of Vδ1 T cells in the immunopathogenesis of PBC is poorly understood. We analysed peripheral blood Vδ1 T cells in PBC patients in active stage (ASP, n = 18), adequate responders (AR, n = 10) and inadequate responders (IAR, n = 4) to ursodeoxycholic acid (UDCA) and an age-matched healthy control group (n = 16) by flow cytometric analysis. The ASP group exhibited a significantly higher proportion and absolute number of Vδ1 T cells, which were also observed in immunofluorescence staining of liver biopsy specimens of PBC patients. Moreover, these Vδ1 T cells expressed a series of activation markers and intracellular cytokines, which may contribute to the immunopathogenesis of PBC. Our study will help to clarify the role of Vδ1 T cells in the development of PBC.

Abstract
OBJECTIVE To investigate some important issues for diagnosis and treatment of idiopathic normal-pressure hydrocephalus (iNPH), such as standardized pre-operative assessment, initial pressure value of diverter pump, and pressure regulation during follow-up. METHODS Twenty six iNPH patients (21 males) who treated in Department of Neurosurgery of 2nd Affiliated Hospital of Zhejiang University School of Medicine from 2011 to 2015 were analyzed retrospectively. The average age was 60.5 year. The analysis focused on the treatment process of iNPH, initial pressure value of diverter pump, choice of diverter pump, and pressure regulation during follow-up. RESULTS As a result, 24 cases (92.3%) had a good prognosis based on their imaging and clinical manifestations. Based on the literature and their clinical experiences, this department established a diagnosis and treatment procedure of iNPH and a pressure regulation procedure for the follow-up of iNPH. Moreover, it is proposed that choosing an anti-gravity diverter pump and making an initial pressure value 20 mmH2O less than pre-surgical cerebrospinal pressure may be beneficial for the prognosis. CONCLUSION This standardized diagnosis and treatment procedure for iNPH is practical and effective.

Abstract
This experiment was conducted to investigate effect of rubber seed oil compared with flaxseed oil when fed alone or in combination on milk yield, milk composition, and α-linolenic acid (ALA) concentration in milk of dairy cows. Forty-eight mid-lactation Holstein dairy cows were randomly assigned to 1 of 4 treatments according to a completely randomized design. Cows were fed a basal diet (control; CON) or a basal diet supplemented with 4% rubber seed oil (RO), 4% flaxseed oil (FO), or 2% rubber seed oil plus 2% flaxseed oil (RFO) on a dry matter basis for 9 wk. Feed intake, milk protein percentage, and milk fat levels did not differ between the treatments. Cows fed the RO, FO, or RFO treatments had a higher milk yield than the CON group (up to 10.5% more), whereas milk fat percentages decreased. Compared with the CON, milk concentration of ALA was substantially higher in cows receiving RO or RFO, and was doubled in cows receiving FO. The ALA yield (g/d) increased by 31.0, 70.3, and 33.4% in milk from cows fed RO, FO, or RFO, respectively, compared with the CON. Both C18:1 trans-11 (vaccenic acid) and C18:2 cis-9,trans-11 (conjugated linoleic acid; CLA) levels were higher in cows fed added flaxseed or rubber seed oil. The CLA yield (g/d) increased by 336, 492, and 484% in cows fed RO, FO, or RFO, respectively, compared with the CON. The increase in vaccenic acid, ALA, and CLA was greater in cows fed RFO than in cows fed RO alone. Compared with the CON, the milk fat from cows fed any of the dietary supplements had a higher concentration of unsaturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids; conversely, the saturated fatty acids levels in milk fat were 30.5% lower. Insulin and growth hormones were not affected by dietary treatments; however, we noted an increase in both cholesterol and nonesterified fatty acids levels in the RO, FO, or RFO treatments. These results indicate that rubber seed oil and flaxseed oil will increase milk production and the concentration of functional fatty acids (ALA, vaccenic acid, and CLA) in milk fat while decreasing the content of saturated fatty acids.

Abstract
Melanisation has been considered to be an important virulence factor of Fonsecaea monophora. However, the biosynthetic mechanisms of melanisation remain unknown. We therefore used next generation sequencing technology to investigate the transcriptome and digital gene expression data, which are valuable resources to better understand the molecular and biological mechanisms regulating melanisation in F. monophora. We performed de novo transcriptome assembly and digital gene expression (DGE) profiling analyses of parent (CBS 122845) and albino (CBS 125194) strains using the Illumina RNA-seq system. A total of 17 352 annotated unigenes were found by BLAST search of NR, Swiss-Prot, Gene Ontology, Clusters of Orthologous Groups and Kyoto Encyclopedia of Genes and Genomes (KEGG) (E-value <1e‒5). A total of 2 283 unigenes were judged to be the differentially expressed between the two genotypes. We identified most of the genes coding for key enzymes involved in melanin biosynthesis pathways, including polyketide synthase (pks), multicopper oxidase (mco), laccase, tyrosinase and homogentisate 1,2-dioxygenase (hmgA). DEG analysis showed extensive down-regulation of key genes in the DHN pathway, while up-regulation was noted in the DOPA pathway of the albino mutant. The transcript levels of partial genes were confirmed by real time RT-PCR, while the crucial role of key enzymes was confirmed by either inhibitor or substrate tests in vitro. Meanwhile, numbers of genes involved in light sensing, cell wall synthesis, morphology and environmental stress were identified in the transcriptome of F. monophora. In addition, 3 353 SSRs (Simple Sequence Repeats) markers were identified from 21 600 consensus sequences. Blocking of the DNH pathway is the most likely reason of melanin deficiency in the albino strain, while the production of pheomelanin and pyomelanin were probably regulated by unknown transcription factors on upstream of both pathways. Most of genes involved in environmental tolerance to oxidants, irradiation and extreme temperatures were also assembled and annotated in transcriptomes of F. monophora. In addition, thousands of identified cSSR (combined SSR) markers will favour further genetic linkage studies. In conclusion, these data will contribute to understanding the regulation of melanin biosynthesis and help to improve the studies of pathogenicity of F. monophora.

Abstract
AIM: To compare the efficacy and safety of polypropylene OP patch and EasyProsthesis surgical mesh in tension-free repair of inguinal hernia.
METHODS: From June 2013 to December 2014, 192 patients aged 23-75 years were included. They were divided into two groups: an OP patch group (n = 96) and an EasyProsthesis surgical mesh group (n = 96). Operation time, duration of pain, time to ambulation, hospital stay, complications and recurrence were compared for the two groups.
RESULTS: Compared with EasyProsthesis surgical mesh, polypropylene OP patch significantly decreased operation time (57.32 min ± 17.39 min vs 75.42 min ± 15.33 min, P < 0.05) and duration of pain (1.34 d ± 0.56 d vs 1.76 d ± 0.76 d, P < 0.05), and reduced the rates of local foreign body sensation [25 (26.04%) vs 9 (9.38%), P < 0.05] and numbness [16 (16.70%) vs 3 (1.04%), P < 0.05]. Beside, no recurrence or chronic pain was reported in both groups during 6 mo of follow-up. There was no significant difference in time to ambulation or hospital stay between the two groups.
CONCLUSION: OP patch for tension-free repair of inguinal hernia is safe and effective, and can simplify the surgical procedure and reduce postoperative patient discomfort.

Abstract
Environmental influences on the development and progression of dental caries are well known; however, there is little evidence of a genetic component imparting susceptibility to dental caries. The aim of this study was to investigate the relationship between a single nucleotide polymorphism in the vitamin D receptor TaqI locus and dental caries susceptibility in a Chinese population. This case-control study was conducted with a case group (264 patients with dental caries from northwestern China) and a control group (219 individuals without dental caries or systemic disease from the same area). DNA was extracted from the peripheral venous blood of the study participants; the distribution of TaqI locus genotypes and allele frequencies was determined via polymerase chain reaction-restriction fragment length polymorphism. The data obtained were statistically analyzed using the Hardy-Weinberg equilibrium and Chi-square test. The frequency of the Tt genotype in the case group (14.0%) was significantly higher than that in the control group (4.3%), as determined using the genotype TT as the reference. The risk of dental caries was increased 3.8-fold in individuals with the heterozygous Tt genotype compared to that in the individuals with the TT genotype. The proportion of the 't' allele in the case group (7.0%) and the control group (2.1%) was observed to be significantly different [P = 0.0003; OR = 3.592, confidence interval 95% (1.790-7.208)]. Our results therefore suggested that the allele 't' might be a genetic factor determining dental caries susceptibility in individuals from the northwest of China.

Abstract
Elaeagnus mollis Diels is a group of shrubs and dwarf trees endemic to China and are endangered plants. However, the reason why these plants are endangered remains controversial. The current study aimed to explore the endangered status of E. mollis from a genetic perspective and to propose conservation strategies for this species. Using 16 polymorphic allozyme loci, the population genetic structure was investigated for three populations representing the taxa and variants. The variants exhibited relatively high levels of genetic variation compared to other woody shrubs with similar geographic distributions. The overall genetic diversity (HE = 0.352) was elevated compared to long-lived woody angiosperms. The average number of alleles per locus (A), percentage polymorphic loci (P), and observed heterozygosity (HO) were 2.0, 85.2, and 0.371, respectively. Furthermore, gene flow estimates within the population groups were also elevated. The life history and habitats of E. mollis play major roles in the levels of genetic diversity. The results of this study may help to device strategies for preserving the genetic diversity of E. mollis and for promoting planting.

Abstract
Tenofovir disoproxil fumarate (TDF) has demonstrated long-term efficacy and a high barrier to resistance in multiple chronic hepatitis B (CHB) populations outside of China. This study aimed to evaluate the efficacy and safety of TDF compared with adefovir dipivoxil (ADV) in Chinese patients with CHB during 48 weeks of treatment (ClinicalTrial.gov number, NCT01300234). A Phase 3, multicentred, randomized, double-blind, controlled trial compared the efficacy and safety of TDF with ADV in Chinese patients with CHB. The primary endpoint was the proportion of patients with HBV DNA <400 copies/mL in each treatment group at Week 48, using an unpooled Z-test for superiority. Secondary endpoints included viral suppression, serologic response, histological improvement, normalization of alanine aminotransferase (ALT) levels and the emergence of resistance mutations. A total of 509 patients, 202 hepatitis B e antigen (HBeAg)-positive and 307 HBeAg-negative, with HBV DNA ≥10(5) copies/mL received either TDF 300 mg od or ADV 10 mg od. At Week 48, TDF demonstrated superior viral suppression compared with ADV in both HBeAg-positive (76.7% vs 18.2%, P < 0.0001) and HBeAg-negative (96.8% vs 71.2%, P < 0.0001) patients. The majority of patients in both treatment arms achieved ALT normalization (>85%). No resistance to TDF was observed. The frequency of adverse events was comparable between treatment arms (TDF 3.9% vs ADV 4.8%). In this double-blind, randomized, clinical trial, TDF demonstrated superiority over ADV with respect to viral suppression in Chinese patients with CHB at 48 weeks of treatment and without the development of resistance.

Abstract
There is currently no effective vaccine to prevent dengue infection, despite the existence of multiple studies on potential methods of immunization. The aim of the present study was to explore the effect of DNA and/or recombinant protein on levels of neutralizing antibodies. For this purpose, envelope domain IIIs of dengue serotypes 1 and 2 (DEN-1/2)were spliced by a linker (Gly‑Gly‑Ser‑Gly‑Ser)3 and cloned into the prokaryotic expression plasmid pET30a (+) and eukaryotic vector pcDNA3.1 (+). The chimeric bivalent protein was expressed in Escherichia coli, and one‑step purification by high‑performance liquid chromatography was conducted. Protein expression levels of the DNA plasmid were tested in BHK‑21 cells by indirect immunofluorescent assay. In order to explore a more effective immunization strategy and to develop neutralizing antibodies against the two serotypes, mice were inoculated with recombinant bivalent protein, the DNA vaccine, or the two given simultaneously. Presence of the specific antibodies was tested by ELISA and the presence of the neutralizing antibodies was determined by plaque reduction neutralization test. Results of the analysis indicated that the use of a combination of DNA and protein induced significantly higher titers of neutralizing antibodies against either DEN‑1 or DEN‑2 (1:64.0 and 1:76.1, respectively) compared with the DNA (1:24.7 and 1:26.9, DEN‑1 and DEN‑2, respectively) or the recombinant protein (1:34.9 and 1:45.3 in DEN‑1 and DEN‑2, respectively). The present study demonstrated that the combination of recombinant protein and DNA as an immunization strategy may be an effective method for the development of a vaccine to prevent dengue virus infection.

Abstract
Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

Abstract
Free gossypol residues in tissues or milk from feeding whole cottonseed and cottonseed meal were measured for their effect on health of dairy cows and humans. Forty lactating cows were randomly assigned to 5 treatments in a 60-d experiment to investigate the effects of sources and dietary level of gossypol on plasma and milk gossypol concentrations in lactating cows. Five experimental diets had identical net energy for lactation and crude protein content on a dry matter (DM) basis. Soybean meal was the main protein ingredient used in the control diet. Cottonseed meal (CSM) or whole cottonseed (WCS) substituted for part of the soybean meal in the other 4 diets. Gossypol levels in the 5 diets were 0 (control), 91.15 mg/kg of DM in CSM1, 117.31mg/kg of DM in CSM2, 385.43 mg/kg of DM in WCS1, and 611.13 mg/kg in WCS2. Yields of 3.5% fat-corrected milk were significantly higher for cows in the WCS2 group; cows in the CSM1 and WCS1 groups showed no differences but both were numerically higher than the control and CSM2 groups. Milk protein concentration was lower for cows consuming WCS1 compared with the control group. Lactose concentration was lower for cows in the CSM2 group compared with the WCS2 group, but no differences were observed among other diets. Aspartate aminotransferase in serum was significantly higher for the WCS2 group compared with the control and WCS1 groups, but no difference was observed with the CSM1 and CSM2 groups. Concentrations of gossypol in plasma and milk of cows in the WCS1 and WCS2 groups were both higher than those of the other groups. No adverse effects were observed on cows fed diets containing 12.0% CSM, and no gossypol was found in plasma and milk. When WCS comprised 15% of the diet DM, yields of 3.5% fat-corrected milk were increased in cows and gossypol was detected in plasma and milk but not at harmful levels.

Abstract
We report a bound state of the one-dimensional two-particle (bosonic or fermionic) Hubbard model with an impurity potential. This state has the Bethe-ansatz form, although the model is nonintegrable. Moreover, for a wide region in parameter space, its energy is located in the continuum band. A remarkable advantage of this state with respect to similar states in other systems is the simple analytical form of the wave function and eigenvalue. This state can be tuned in and out of the continuum continuously.

Abstract
We show that a quenched and relaxed completely integrable system is hardly distinguishable from the corresponding generalized Gibbs ensemble in a dynamical sense. To be specific, the response of the quenched and relaxed system to a second quench can be accurately reproduced by using the generalized Gibbs ensemble as a substitute. Remarkably, as demonstrated with the transverse Ising model and the hard-core bosons in one dimension, not only the steady values but even the transient, relaxation dynamics of the physical variables can be accurately reproduced by using the generalized Gibbs ensemble as a pseudoinitial state. This result is an important complement to the previously established result that a quenched and relaxed system is hardly distinguishable from the generalized Gibbs ensemble in a static sense. The relevance of the generalized Gibbs ensemble in the nonequilibrium dynamics of completely integrable systems is then greatly strengthened.

Abstract
AIM: To investigate the role of nitric oxide in ischemia-reperfusion injury and cell apoptosis following pancreas-duodenal transplantation in rats.
METHODS: A total of 168 SD rats were used in the study. Seventy-two female rats with diabetes induced by intraperitoneal injection of alloxan were used as donors, and 96 male rats were used as recipients. A rat model of pancreas-duodenal transplantation was developed using dual cannula technique. The 96 male rats were randomly divided into sham group, control group, L-Arg group, and L-NAME group, with 24 rats in each group. Rats of each group were randomly killed at 1 h, 3 h and 6 h. Serum nitric oxide and amylase levels were examined, and pancreatic injury was evaluated. The expression of iNOS in pancreatic tissue was detected by immunohistochemistry, and pancreatic cell apoptosis was evaluated by flow cytometry.
RESULTS: Serum nitric oxide and amylase, pancreas injury scores were significantly higher in the control group (1 h, 3 h, 6 h) than in the sham group (all P < 0.01). Serum nitric oxide was significantly higher and serum amylase and pancreas injury scores were significantly lower in the L-Arg group than in the control group (1 h, 3 h, 6 h) (all P < 0.01). Serum nitric oxide was significantly lower and serum amylase and pancreas injury scores were significantly higher in the L-NAME group than in the control group (all P < 0.01). The percentage of viable cells was significantly lower and apoptosis rate was significantly higher in the control group than in the sham group (all P < 0.01). The percentage of viable cells was significantly lower and apoptosis rate was significantly higher in the L-Arg and L-NAME groups than in the control group (all P < 0.01). The number of necrotic cells in the L-Arg group was lower than that in the control group but higher than that in the L-NAME group (all P < 0.01).
CONCLUSION: Nitric oxide plays a dual role in ischemia-reperfusion injury and cell apoptosis following pancreas-duodenal transplantation in rats.

Abstract
AIMS To examine the mechanism of ozone-induced damage to cytoplasmic membrane and cell ultrastructure of Pseudomonas aeruginosa ATCC27853. METHODS AND RESULTS Cell suspensions of Ps. aeruginosa ATCC27853 were treated with ozonated water. The leakages of cellular potassium (K⁺), magnesium (Mg²⁺) and adenosine triphosphate (ATP), determined by inductively coupled plasma/mass spectrometry (ICP/MS) and a commercial bioluminescence assay kit, were to assess ozone-induced damage to the cytoplasmic membrane. Maximum leakages of K⁺ and Mg²⁺ were attained, respectively, at 0·53 mg l⁻¹ ozone after 0·5 and 2 min with > 99% inactivation of culturable bacteria, while that of ATP was achieved at 0·67 mg l⁻¹ ozone after 1 min. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) revealed that treated cells retained intact shapes and cytoplasm agglutinations and vacuoles occurred. CONCLUSIONS Ozone inactivates Ps. aeruginosa ATCC27853 by the combined results of increased cytoplasmic membrane permeability and cytoplasm coagulation, rather than by severe membrane disruption and cell lysis. SIGNIFICANCE AND IMPACT OF THE STUDY Pseudomonas aeruginosa is a common water-related pathogen. These insights into the leakage of cytoplasmic components and ultrastructural changes provide evidence for the mechanisms of ozone-mediated inactivation.

Abstract
In the title compound, [Fe(C38H38N10)](ClO4)2·CH3OH, the FeII atom has a distorted octahedral coordination environment with four benzimidazol N atoms and two amino N atoms from an N,N,N′,N′-tetrakis(benzimidazol-2-ylmethyl)cyclohexane-1,2-trans-diamine ligand. The uncoordinated solvent methanol molecule is hydrogen bonded to an O atom of a perchlorate anion. One of the perchlorate anions is disordered over two sets of sites with occupancy factors of 0.539 (14) and 0.461 (14). N—H⋯O and C—H⋯O hydrogen bonds, as well as π–π stacking interactions between the imidazol rings and between the imidazol and benzene rings [centroid–centroid distances = 3.714 (2) and 3.705 (2) Å] give rise to a three-dimensional network.
