Abstract
Objective:To build a digital cross-sectional images date set of human normal larynx with high-precision.Method:A fresh frozen normal human larynx was embedded using Kawamot's Film Method and then serially sectioned at 10 μm with a LeicaCM3600XP Cryomacrotome, meanwhile digital images of the block surface were recorded after every section with a Nikon D750 camera and stored respectively as JPG and RAW files. All images were cropped to display a constant area on the block surface by photoshop7 and stored as TIFF files. Result:A total of 6 656 images were recorded in 24-bit RGB resolution, the complete data file is 97.5 GB and 174 GB. After elimination of image size variation, all images were re-sampled at a final resolution of 40 μm/pixel and the complete data file is 107 GB. Conclusion:It's feasible to use the combination of Kawamot's Film Method,Digital Single Lens Reflex with high-resolution and regular block face-based alignment to build high-precision digital images date set, which could apply to some partial organs that resemble larynx.

Abstract
Larynx is a complicated organ of significant functions including breathing, voicing, protecting and so on, so it's important for anyone involved in the filed to know more about the multiple structures of the complex. Although there are numerous 2D images of larynx, it's still difficult for the observers to understand the organ well, so it's necessary to establish a real digital modal of larynx. With the development of computer and image processing technologies, medical imaging datasets have been used for the reconstruction of larynx. And the complete of visible human project also provides colorful cross-sectional images for reconstruction. The article reviews the development of the reconstruction of larynx, and predicts the possible developing direction of future 3D reconstruction.

Abstract
Aims To present our experience of using a combination of intra-articular osteotomy and external fixation to treat different deformities of the knee. Patients and Methods A total of six patients with a mean age of 26.5 years (15 to 50) with an abnormal hemi-joint line convergence angle (HJLCA) and mechanical axis deviation (MAD) were included. Elevation of a tibial hemiplateau or femoral condylar advancement was performed and limb lengthening with correction of residual deformity using a circular or monolateral Ilizarov frame. Results At a mean follow-up of 2.8 years (1.5 to 4.1), the mean HJLCA improved from 15.6° (10° to 23°) pre-operatively to 0.4° (0° to 2°). The mean MAD improved from 70.0 mm (20.1 to 118.5) pre-operatively to 9.1 mm (3 to 15). The mean tibiofemoral angle improved from 31.0° (8° to 54°) pre-operatively to 4.9° (2° to 8°). The mean limb-length discrepancy decreased from 6.3 cm (2.9 to 13.6) pre-operatively to 1.1 cm (0 to 5). All osteotomies and distraction zones healed without complications. Conclusion The use of intra-articular corrective osteotomies combined with the Ilizarov technique allowed correction of deformities of the knee joint with satisfactory HJLCA and overall mechanical axis in six patients with a good functional and cosmetic outcome in the short term.

Abstract
In many plant species, including rose (Rosa hybrida), flower senescence is promoted by the gaseous hormone ethylene and inhibited by the cytokinin (CTK) class of hormones. However, the molecular mechanisms underlying these antagonistic effects are not well understood. In this study, we characterized the association between a pathogenesis-related PR-10 family gene from rose (RhPR10.1) and the hormonal regulation of flower senescence. Quantitative reverse transcription PCR analysis showed that RhPR10.1 was expressed at high levels during senescence in different floral organs, including petal, sepal, receptacle, stamen, and pistil, and that expression was induced by ethylene treatment. Silencing of RhPR10.1 expression in rose plants by virus-induced gene silencing accelerated flower senescence, which was accompanied by a higher ion leakage rate in the petals, as well as increased expression of the senescence marker gene RhSAG12 CTK content and the expression of three CTK signaling pathway genes were reduced in RhPR10.1-silenced plants, and the accelerated rate of petal senescence that was apparent in the RhPR10.1-silenced plants was restored to normal levels by CTK treatment. Finally, RhHB6, a homeodomain-Leu zipper I transcription factor, was observed to bind to the RhPR10.1 promoter, and silencing of its expression also promoted flower senescence. Our results reveal an ethylene-induced RhHB6-RhPR10.1 regulatory module that functions as a brake of ethylene-promoted senescence through increasing the CTK content.

Abstract
Episcleritis and scleritis are relatively rare ocular diseases, which are commonly associated with rheumatic diseases including systemic lupus erythematosus (SLE). To investigate clinical and laboratory features of SLE-associated episcleritis and scleritis, we now report 4 cases of inpatients who were diagnosed with episcleritis or scleritis secondary to SLE from September 2005 to July 2016 in the Department of Rheumatology and Immunology in Peking University People's Hospital. Demographic, clinical and laboratory characteristics were summarized together with the treatment regimen and the prognosis; the literature was reviewed. There were 3 female and 1 male patients. The average age was (49.0±23.8) years and the mean duration of SLE at the onset of episcleritis or scleritis was (2.1±1.4) years. In addition to the eye involvement, the patients had mucocutaneous manifestations, serositis, lupus nephritis and interstitial pneumonia simultaneously; in the past, 1 patient experienced arthritis, 2 presented Raynaud's phenomenon, and 2 had hematologic involvement. All the patients had antinuclear antibody (ANA) of high titer. The anti double-stranded DNA (ds-DNA) antibody titers were increased in 2 patients. Three patients had positive anti-nucleosome antibody (ANuA) while the other 1 patient did not test it. The complement levels were decreased in 3 patients. The systemic lupus erythematosus disease activity index (SLEDAI) scores were more than 4 points in all the patients (ranging from 7-16), suggesting active disease. Ocular symptoms included pain, redness of the eye and tears. Ophthalmic examinations revealed 3 cases of episcleritis and 1 case of scleritis. Among the 4 patients, 2 patients experienced ocular complications including decrease in vision and uveitis. All the patients were treated with systemic corticosteroids combined with hydroxycloroquine; 3 patients were treated with immunosuppressants (cyclophosphamide in 2 patients and leflunomide in 1 patient). All of the 4 patients received topical steroid and 1 patient received periocular injection of triamcinolone acetonide; 1 patient received topical nonsteroidal anti-inflammatory drug (NSAID).No recurrence of episcleritis or scleritis was observed during the follow-ups. As a conclusion, scleritis and episcleritis, although uncommon, may occur in patients with autoimmune rheumatic diseases including SLE. The occurrence of episcleritis and scleritis may suggest active disease of SLE. Ocular complications need to be aware of in the patients. Prompt diagnosis and treatment was associated with good visual outcomes in the follow-ups.

Abstract
BACKGROUND Signaling through histamine receptors on dendritic cells (DCs) may be involved in the effector phase of peanut-induced intestinal anaphylaxis. OBJECTIVES The objective of this study was to determine the role of histamine H1 (H1R) and H4 receptors (H4R) in intestinal allergic responses in a model of peanut allergy. METHODS Balb/c mice were sensitized and challenged with peanut. During the challenge phase, mice were treated orally with the H1R antagonist, loratadine, and/or the H4R antagonist, JNJ7777120. Bone marrow-derived DCs (BMDCs) were adoptively transferred to nonsensitized WT mice. Symptoms, intestinal inflammation, and mesenteric lymph node and intestine mucosal DCs were assessed. Effects of the drugs on DC chemotaxis, calcium mobilization, and antigen-presenting cell function were measured. RESULTS Treatment with loratadine or JNJ7777120 individually partially suppressed the development of diarrhea and intestinal inflammation and decreased the numbers of DCs in the mesenteric lymph nodes and lamina propria. Combined treatment with both drugs prevented the development of diarrhea and intestinal inflammation. In vitro, the combination suppressed DC antigen-presenting cell function to T helper cells and DC calcium mobilization and chemotaxis to histamine. CONCLUSION Blockade of both H1R and H4R in the challenge phase had additive effects in preventing the intestinal consequences of peanut sensitization and challenge. These effects were mediated through the limitation of mesenteric lymph node and intestinal DC accumulation and function. Identification of this histamine H1R/H4R-DC-CD4+ T-cell axis provides new insights into the development of peanut-induced intestinal allergic responses and for prevention and treatment of peanut allergy.

Abstract
Two-dimensional heterostructures with strong spin-orbit coupling have direct relevance to topological quantum materials and potential applications in spin-orbitronics. In this work, we report on novel quantum phenomena in [Pb2BiS3][AuTe2], a new 2D strong spin-orbit coupling heterostructure system. Transport measurements reveal the spin-related carrier scattering is at odds with the Abrikosov-Gorkov model due to strong spin-orbit coupling. This is consistent with our band structure calculations which reveal a large spin-orbit coupling gap of εso = 0.21 eV. The band structure is also characterized by helical-like spin textures which are mainly induced by strong spin-orbit coupling and the inversion symmetry breaking in the heterostructure system.

Abstract
Laryngeal carcinoma is a common malignant tumor in the head and neck, and the squamous cell carcinoma of the larynx is the most prevelance. In view of the importance of laryngeal function and its survival, the choice of the best therapeutic regimen of laryngeal carcinoma must consider the potential survival rate and the change of postoperative function. The margin of laryngeal carcinoma is an important index of preoperative imaging evaluation of laryngeal carcinoma. The accurate determination of the cutting edge determines the operation mode, the success rate, the survival rate and prognosis of the patients with laryngeal carcinoma.In recent years, the method of preoperative evaluation of laryngeal tumors is diverse, including molecular, imaging and endoscopy, among which preoperative imaging is the most common method. The purpose of this study was to summarize the evaluation of different imaging techniques in the assessment of local invasion and recurrence of submucosal tumors in laryngeal carcinoma.

Abstract
The objective of this study was to investigate the prognostic value of peripheral blood monocytes in esophageal squamous cell carcinoma (ESCC) patients who underwent esophagectomy. Records from 218 consecutive patients with histologically diagnosed ESCC who underwent esophagectomy at Qilu Hospital of Shandong University from January 2007 to December 2008 were retrospectively reviewed. The median disease-free survival (DFS) of this cohort was 29.0 months, and the 5-year DFS rate was 34.4%. The median overall survival (OS) was 35.0 months, and the 5-year OS rate was 37.6%. The cut-off value of 0.42 × 109 /L for the absolute monocyte count (AMC) was chosen as optimal to discriminate between survival and death by applying receiver operating curve analysis. There were 131 patients (60.1%) who had high AMC (≥0.42 × 109 /L) preoperatively. We found that AMC was significantly associated with gender, tumor location, and platelet count. Kaplan-Meier survival analysis of patients with high preoperative AMC had a significant worse prognosis for DFS (high vs. low: 27.5% vs. 39.0%, P = 0.015) and OS (high vs. low: 31.1% vs. 44.8%, P = 0.009) than those with low preoperative AMC. In a multivariate analysis, preoperative AMC was an independent prognostic factor for DFS (P = 0.025, hazard ratio [HR]: 1.469, 95% confidence interval [CI]: 1.050-2.054) and OS (P = 0.015, HR: 1.547, 95% CI: 1.088-2.200). In addition, among 140 patients without both preoperative and postoperative therapy, significantly worse OS (P = 0.012) and marginally reduced DFS (P = 0.079) were found in the high AMC cohort versus the low AMC cohort. A higher preoperative absolute peripheral monocyte count can be considered as a useful prognostic marker of ESCC patients who underwent esophagectomy.

Abstract
Aged beef cows (≥ 8 yr of age) produce calves with lower birth and weaning weights. In mammals, aging is associated with reduced hepatic expression of glutamine synthetase (GS) and alanine transaminase (ALT), thus impaired hepatic Gln-Glu cycle function. To determine if the relative protein content of GS, ALT, aspartate transaminase (AST), glutamate transporters (EAAC1, GLT-1), and their regulating protein (GTRAP3-18) differed in biopsied liver tissue of (a) aged vs. young (3 to 4 yr old) nonlactating, nongestating Angus cows (Exp. 1 and 2) and (b) aged mixed-breed cows with and without COMPUDOSE (17β-estradiol) ear implants (Exp. 3), Western blot analyses were performed. In Exp. 1, 12 young (3.62 ± 0.01 yr) and 13 aged (10.08 ± 0.42 yr) cows grazed the same mixed forage for 42 d (August-October). In Exp. 2, 12 young (3.36 ± 0.01 yr) and 12 aged (10.38 ± 0.47 yr) cows were individually fed (1.03% of BW) a corn-silage-based diet to maintain BW for 20 d. For both Exp. 1 and 2, the effect of cow age was assessed by ANOVA using the MIXED procedure of SAS. Cow BW did not change ( ≥ 0.17). Hepatic ALT (78% and 61%) and GS (52% and 71%) protein content (Exp. 1 and 2, respectively) was decreased ( ≤ 0.01), whereas GTRAP3-18 (an inhibitor of EAAC1 activity) increased ( ≤ 0.01; 170% and 136%) and AST, GLT-1, and EAAC1 contents did not differ ( ≥ 0.17) in aged vs. young cows. In Exp. 2, free concentrations (nmol/g) of Glu, Ala, Gln, Arg, and Orn in liver homogenates were determined. Aged cows tended to have less ( = 0.10) free Gln (15.0%) than young cows, whereas other AA concentrations did not differ ( 0.26). In Exp. 3, 14 aged (> 10 yr) cows were randomly allotted ( = 7) to sham or COMPUDOSE (25.7 mg of 17β-estradiol) implant treatment (TRT), and had ad libitum access to alfalfa hay for 28 d. Blood and liver biopsies were collected 14 and 28 d after implant treatment. Treatment, time after implant (DAY), and TRT × DAY effects were assessed by ANOVA using the MIXED procedure of SAS. Cow BW was not affected ( ≥ 0.96). Implant increased ( ≤ 0.02) total plasma estradiol by 220% (5.07 vs. 1.58 pg/mL) and GS protein by 300%, whereas the relative content of other proteins was not altered ( ≥ 0.16). We conclude that hepatic expression of ALT and GS are reduced in aged vs. young cows, and administration of 17β-estradiol to aged cows increases plasma estradiol and hepatic GS, but not that of other proteins that support hepatic Glu metabolism.

Abstract
Spermatogonial stem cells (SSCs) are unique male germline stem cells that support spermatogenesis and male fertility. Long non-coding RNAs (lncRNA) have been identified as key regulators of stem cell fate; however, their role in SSCs has not been explored. Here, we report that a novel spermatogonia-specific lncRNA (lncRNA033862) is essential for the survival of murine SSCs. LncRNA033862 is expressed in early spermatogonia including SSC and was among 805 lncRNAs identified by global expression profiling as responsive to glial cell-derived neurotrophic factor (GDNF), a growth factor required for SSC self-renewal and survival. LncRNA033862 is an antisense transcript of the GDNF receptor alpha1 (Gfra1) that lacks protein coding potential and regulates Gfra1 expression levels by interacting with Gfra1 chromatin. Importantly, lncRNA033862 knockdown severely impairs SSC survival and their capacity to repopulate recipient testes in a transplantation assay. Collectively, our data provide the first evidence that long non-coding RNAs (lncRNAs) regulate SSC fate.

Abstract
OBJECTIVE To explore the clinical value of intraoperative magnetic resonance imaging (iMRI) coregistration combined with position emission tomography/computed tomography (PET/CT) in stereotactic brain biopsy. METHODS Forty nine patients with intracranial lesions were operated by stereotactic biopsy from June 2010 to June 2015 in Tianjin Medical University General Hospital. Seventeen patient's operation was guided by iMRI only (group A), thirty two patients' operation was guided by iMRI and PET/CT (group B). The diagnosis success rate and operation related complications were compared between the two groups. RESULTS PET/CT and iMRI were integrated successfully in all cases of group B. Fourteen patients (82.4%) of group A and all 32 patients (100%) of group B had final diagnosis confirmed by histopathological and immunohistochemical observation. The diagnosis success rate of group B was higher than group A (P<0.05). There were 5 patients in total who had postoperative complication, 2 (11.8%) in group A and 3 (9.3%) in group B, but the difference was not statistically significant. CONCLUSIONS PET/CT based metabolic imaging can be automatically integrated with standard MRI guided stereotactic biopsy. Compared with iMRI only, the combined treatment improves diagnosis success rate without increasing complications; it's safe, and has high clinical efficacy.

Abstract
This study aimed to investigate cytosine methylation profiles in different tobacco (Nicotiana tabacum) cultivars grown in China. Methylation-sensitive amplified polymorphism was used to analyze genome-wide global methylation profiles in four tobacco cultivars (Yunyan 85, NC89, K326, and Yunyan 87). Amplicons with methylated C motifs were cloned by reamplified polymerase chain reaction, sequenced, and analyzed. The results show that geographical location had a greater effect on methylation patterns in the tobacco genome than did sampling time. Analysis of the CG dinucleotide distribution in methylation-sensitive polymorphic restriction fragments suggested that a CpG dinucleotide cluster-enriched area is a possible site of cytosine methylation in the tobacco genome. The sequence alignments of the Nia1 gene (that encodes nitrate reductase) in Yunyan 87 in different regions indicate that a C-T transition might be responsible for the tobacco phenotype. T-C nucleotide replacement might also be responsible for the tobacco phenotype and may be influenced by geographical location.

Abstract
OBJECTIVE Abnormalities in structural and functional brain connectivity have been increasingly reported in patients with bipolar disorder (BD) by recent neuroimaging studies. However, relatively little is known about the changes in functional interaction between the cerebral hemispheres in BD. The present study aimed to examine the interhemispheric functional connectivity of the whole brain in patients with BD II during resting state. METHOD Twenty-six patients with unmedicated BD II depression and 40 normal controls underwent the resting-state functional magnetic resonance imaging. The functional connectivity between any pair of symmetrical interhemispheric voxels (i.e., functional homotopy) was measured by voxel-mirrored homotopic connectivity (VMHC). RESULTS The patients with BD II showed lower VMHC than normal controls in the medial prefrontal cortex and inferior temporal gyrus. No regions of increased VMHC were detected in patients. There were no significant correlations between the VMHC values in these regions and clinical severity of BD symptoms. CONCLUSION These findings suggest substantial impairment of interhemispheric coordination in BD II.

Abstract
AIM To detect the skewness of TCR Vα and TCR Vβ of patients with type 1 diabetes (T1D). METHODS The heparinized venous blood was collected from ten patients with T1D. The peripheral blood lymphocytes (PBL) were isolated and used to extract mRNA. Reverse amplyfication was performed for cDNA synthesis. The skewness of TCR Vα and Vβ was detected with real-time florescence quantitative polymerase chain reaction (RQ-PCR) and analyzed by DNA melting-curve analysis technique, respectively. RESULTS Among the TCR Vα genes, the skewness frequency rate (SFR) of Vα22 was 30%; both of Vα5 and Vα24 were 20%; Vα28 was the only restricted-clone gene with the SFR of 10%. In all the Vβ genes, Vβ7 and Vβ17 were the the highest expression genes, and their SFRs were both 60%. Vβ11 was near them with the SFR of 40%; the restricted clonal genes were Vβ18 and Vβ20, their SFRs were 10% and 20%, respectivley. CONCLUSION There are skewd genes in TCR Vα and TCR Vβ, which are probably relative to the onset of T1D.

Abstract
Immune dysfunction is the main characteristic of sepsis. T cell Ig and mucin domain protein 3 (Tim-3) on the monocytes has been reported to promote immune homeostasis during sepsis, but the influences of plasm soluble Tim-3 (sTim-3) on the immune system during sepsis remain unknown. Here, 100 patients with different severities of sepsis (40 sepsis, 42 severe sepsis, and 18 septic shock) were enrolled in this study. The Tim-3 and human leukocyte antigen-DR (HLA-DR) on the circulating monocytes were detected using flow cytometry. Plasma sTim-3 was detected by enzyme-linked immunosorbent assay. Inflammatory factors and two kinds of A disintegrin and metalloprotease (ADAM) - ADAM10 and ADAM17 were assessed. The Tim-3 and HLA-DR on the monocytes decreased with increasing sepsis severity. The sTim-3 was reduced in the sepsis and severe sepsis patients but was elevated in the septic shock patients who exhibited significant immunosuppression as predicted by HLA-DR. sTim-3 levels were negatively correlated with IL-12 and TNF-α. ADAM10 and ADAM17, sheddases of Tim-3, exhibited trends toward elevations in the septic shock group. In conclusion, sTim-3 was involved in the development of sepsis. The homeostasis-promoting role of the Tim-3 on the monocytes was disrupted, while the inhibitory role of sTim-3 emerged during sepsis-induced immunosuppression.

Abstract
The full-length complementary (c)DNA of vacuolar-type-H(+) -ATPase B1 gene (vhab1) in marbled eel Anguilla marmorata with 1741 base pairs (bp) was identified. It contained a 1512 bp open reading frame encoding a polypeptide with 503 amino acids (55·9 kDa), an 83 bp 5'-untranslated region (UTR) and a 146 bp 3'-UTR. The expression levels of A. marmorata vhab1 in gill and kidney of A. marmorata were evaluated at different intervals during the exposure to various salinities (0, 10 and 25). The results indicated that the expression levels of A. marmorata vhab1 messenger (m)RNA in gill and kidney had a significant increase and reached the highest level at 1 h in brackish water (BW, salinity 10) group and 6 h in seawater (SW, salinity 25) group. Therefore, salinity did affect the relative expression level of A. marmorata vhab1 mRNA in gills, which exhibited the enhancement by c. 44 times in SW group when compared with that in fresh water. No remarkable difference in the expression of A. marmorata vhab1 mRNA was observed after 15 days of SW exposure (P > 0·05). V-H(+) -ATPase activity exhibited an increase by two- to three-fold when compared with that in gill and kidney from the control group. The consequence primarily suggested that A. marmorata vhab1 gene product in elvers from A. marmorata plays an important role in adaptation response to SW.

Abstract
BACKGROUNDS Recurrence is the most important factor associated with death of gastric cancer patients after surgery. The aim of this study was to explore the prognosis factors and the effective therapy for recurrent gastric cancer (RGC) patients after radical resection. METHODS The clinical data of 144 RGC patients who underwent radical resection from January 1999 to March 2004 were reviewed. The 15 clinicopathological factors and treatment modalities on the survival were analyzed. Univariate and multivariate analyses were performed to investigate the prognostic significance of these factors for RGC. RESULTS The early recurrence (<2 years) was found in 90 patients, while late recurrence (≥2 years) occurred in 54 patients. The 2-year cumulative survival rates were 23.8 % for recurrent patients receiving chemotherapy plus surgery vs. 1.2 % in patients having chemotherapy only (p < 0.001), while the median survival time was 11.0 months vs. 6.0 months (p < 0.001). Multivariate analysis indicated TNM stage after the first operation (p = 0.048), iASPP overexpression (p = 0.013), time to recurrence (p < 0.001) and treatment of recurrence (p < 0.001) as independent prognostic factors. CONCLUSIONS Surgery combined with chemotherapy for recurrent gastric cancer patients achieves ideal long-term prognosis, which should perform actively.

Abstract
Casein kinase 2 interacting protein 1 (CKIP1) is a specific interacting protein of the casein kinase 2 (CK2) α subunit, and, by binding CK2 and other proteins, functions as an adaptor to regulate a series of cellular functions. Previous studies suggested that CKIP1 might play an important role in regulating oncogenic activities. However, few studies examining the function of CKIP1 in cancer cells have been performed. The present study aimed to investigate the role of CKIP1 in lung cancer. CKIP1 mRNA expression was detected in 5 human lung cancer cell lines (H-125, H1299, LTEP-A-2, SPC-A-1, and NCL-H446) by semi-quantitative RT-PCR, and in 10 noncancerous lung tissues and 30 non-small lung cancer tissues by real-time quantitative PCR. A lentivirus-mediated small interfering RNA (siRNA) was used to knock down CKIP1 expression in the H1299 cell line. To elucidate the impact of CKIP1 downregulation on H1299 cells, cell proliferation, DNA synthesis, and cell cycle distribution and apoptosis were measured by high content screening assay, BrdU incorporation, and flow cytometric analyses, respectively. CKIP1 mRNA was highly expressed both in H1299 cells and lung cancer tissues. We found that downregulation of CKIP1 resulted in suppression of proliferation and colony-forming ability of H1299 cells, and led to S phase cell cycle arrest and G2 phase promotion, as well as a significant enhancement of H1299 cell apoptosis. Our study indicated that high expression levels of CKIP1 were associated with the development of lung cancer, and that CKIP1 knockdown may block tumor cell growth mainly by promoting cell apoptosis.

Abstract
Humanin (HN) has cytoprotective action on male germ cells after testicular stress induced by heat and hormonal deprivation. To examine whether HN has protective effects on chemotherapy-induced male germ cell apoptosis, we treated four groups of adult rats with (i) vehicle (control), (ii) HN, (iii) cyclophosphamide (CP); or (iv) HN+CP. To investigate whether the protective effects of HN on germ cells require the presence of Leydig cells, another four groups of rats were pre-treated with ethane dimethanesulfonate (EDS), a Leydig cell toxicant, to eliminate Leydig cells. After 3 days, when Leydig cells were depleted by EDS, we administered: (i) vehicle, (ii) HN, (iii) CP; or (iv) HN+CP to rats. All rats were killed 12 h after the injection of HN and/or CP. Germ cell apoptosis was detected by TUNEL assay and quantified by numerical count. Compared with control and HN (alone), CP significantly increased germ cell apoptosis; HN +CP significantly reduced CP-induced apoptosis at early (I-VI) and late stages (IX-XIV) but not at middle stages (VII-VIII) of the seminiferous epithelial cycle. Pre-treatment with EDS markedly suppressed serum and intratesticular testosterone (T) levels, and significantly increased germ cell apoptosis at the middle (VII-VIII) stages. CP did not further increase germ cell apoptosis in the EDS-pre-treated rats. HN significantly attenuated germ cell apoptosis at the middle stages in EDS pre-treated rats. To investigate whether HN has any direct effects on Leydig cell function, adult Leydig cells were isolated and treated with ketoconazole (KTZ) to block testosterone synthesis. HN was not effective in preventing the reduction of T production by KTZ in vitro. We conclude that HN decreases CP and/or EDS-induced germ cell apoptosis in a stage-specific fashion. HN acts directly on germ cells to protect against EDS-induced apoptosis in the absence of Leydig cells and intratesticular testosterone levels are very low.

Abstract
OBJECTIVE The objective of this study was to investigate the effects of osteoprotegerin (OPG) gene therapy on alveolar bone resorption caused by experimental periodontitis in rats, thus forming a foundation for potential clinical applications of OPG gene therapy in the treatment of periodontitis and peri-implantitis. MATERIAL AND METHODS To study the effects of OPG on alveolar bone protection, an experimental periodontitis model was used by placing a bacterial plaque retentive silk ligature in the gingival sulcus around the maxillary second molar tooth, injection of Porphyromonas gingivalis and high carbohydrate diet. A total of 30 Sprague-Dawley rats were randomly divided into three groups, with 10 rats in each group: group I (control) was treated with 10 μL normal saline injection; group II with 10 μL mock vector; and group III with 10 μL local OPG gene transfer by transfection with in vitro constructed pcDNA3.1-human OPG (pcDNA3.1-hOPG). A subperiosteal injection was done adjacent to the second molars on days 0, 7, 14 and 21. Four weeks later, all animals were killed and radiographic, histological and immunohistochemical examinations were performed. Statistical analysis included ANOVA and LSD-Bonferroni test. RESULTS Group III (OPG gene therapy) had significantly enhanced (p < 0.05) integrated optical density of OPG, had significantly decreased alveolar bone resorption volume and active osteoclast number (p < 0.05) through descriptive histological examination when compared with the other two groups at week 4. CONCLUSION Local recombinant OPG plasmid-mediated gene therapy suppresses osteoclastogenesis in vivo and inhibits alveolar bone height reduction caused by experimental periodontitis in rats. OPG gene therapy may be beneficial in preventing progressive periodontal bone loss.

Abstract
BACKGROUND AND PURPOSE Annexin A1 (AnxA1) is an endogenous anti-inflammatory protein and agonist of the formyl peptide receptor 2 (FPR2). However, the potential for therapeutic FPR ligands to modify immune-mediated disease has been little explored. We investigated the effects of a synthetic FPR agonist on joint disease in the K/BxN model of rheumatoid arthritis (RA) and RA fibroblast-like synoviocytes (FLS). EXPERIMENTAL APPROACH Arthritis was induced by injection of K/BxN serum at day 0 and 2 in wild-type (WT) or AnxA1(-/-) mice and clinical and histopathological manifestations measured 8-11 days later. WT mice were given the FPR agonist compound 43 (Cpd43) (6 or 30 mg·kg(-1) i.p.) for 4 days. Effects of AnxA1 and Cpd43 on RANKL-induced osteoclastogenesis were assessed in RAW 264.7 cells and human RA FLS and macrophages. KEY RESULTS Treatment with Cpd43 before or after the onset of arthritis reduced clinical disease severity and attenuated synovial TNF-α and osteoclast-associated gene expression. Deletion of AnxA1 in mice exacerbated arthritis severity in the K/BxN model. In vitro, Cpd43 suppressed osteoclastogenesis and NFAT activity elicited by RANKL, and inhibited IL-6 secretion by mouse macrophages. In human RA joint-derived FLS and monocyte-derived macrophages, Cpd43 treatment inhibited IL-6 release, while blocking FPR2 or silencing AnxA1 increased this release. CONCLUSIONS AND IMPLICATIONS The FPR agonist Cpd43 reduced osteoclastogenesis and inflammation in a mouse model of RA and exhibited anti-inflammatory effects in relevant human cells. These data suggest that FPR ligands may represent novel therapeutic agents capable of ameliorating inflammation and bone damage in RA.

Abstract
Identification of resistance (R) genes to races of Magnaporthe oryzae in rice (Oryza sativa) germplasm is essential for the development of rice cultivars with long-lasting blast resistance. In the present study, one major quantitative trait locus, qPi93-3, was fine mapped using a recombinant inbred line (RIL), F8 RIL171, derived from the cross between 'Nipponbare' and '93-11'. RIL171 contained a heterozygous qPi93-3 allele which was found to be resistant against nine U.S. common races-ID1, IA1, IB49, IE1, IA45, IB1, IC17, IB45, and IH1-of M. oryzae. An F2 mapping population consisting of 2,381 individuals derived from RIL171 was evaluated with a field isolate (race) ARB82 (IA1) of M. oryzae under greenhouse conditions. Disease reaction of a resistant/susceptible ratio of 3:1 was identified with F2:F3 families. In total, 12 simple sequence repeat markers spanning qPi93-3 were used for fine mapping. Consequently, qPi93-3 was delimited to 4.2 Mb between RM3246 and RM7102. Three insertion-deletion (InDel) markers located between RM3246 and RM7102, that had previously used to map Pi61(t), showed that qPi93-3 was Pi61(t). The existence of Pi61(t) in 136 rice germplasm lines from the United States Department of Agriculture rice core collection was evaluated using Pi61(t)-specific InDel markers. Pi61(t) was identified as a source of resistance in 5 of the 136 lines. The characterized germplasm will be useful for rice breeders to use for improving blast resistance.
