Abstract
A collection of plasma cells in the skin can represent a broad spectrum of disease entities. Secondary syphilis, primary cutaneous plasmacytoma, primary cutaneous plasmacytosis, cutaneous lymphoid hyperplasia and nodular amyloidosis are considered possible differential diagnoses. The primary cutaneous plasma cell disorders can range from malignant to benign plasma cell neoplasms. The malignant conditions are neoplastic diseases having monoclonal proliferations, rapid progression and fatal outcome while the benign plasma cell disorders usually show polyclonality, chronicity and benign process, including plasmacytosis. We present a case of cutaneous plasmacytosis. The patient was a 34-year-old man, presented with disseminated reddish-brown plaques and nodules on the right side of the hips, inguinal groove, and the thigh. Histopathologically, mature plasma cells perivascular infiltrates were observed mainly in the dermis. Polyclonality of infiltrating plasma cells with coexistence of both kappa and gamma chain-positive cells demonstrated with immunohistochemistry, as well as CD20+++, CD38++++, CD79a++++, CD138++, Ki67<30%. The diagnosis, cutaneous plasmacytosis, was established by the pertinent laboratory findings. Primary cutaneous plasmacytosis was an uncommon reactive lymphoplasmacytic disorder of uncertain etiology. Cutaneous plasmacytosis is a rare disease characterized by peculiar multiple eruptions and hyper gamma globulinemia. It has been mainly described in patients of Japanese descent, with only few reports in Caucasians and Chinese, although information concerning the disorder was limited to individual case reports. Cutaneous plasmacytosis is a rare disorder, which is characterized by multiple red to dark-brown nodules and plaques on the trunk and usually associated with polyclonal hyper gamma globulinaemia. Primary cutaneous plasmacytosis or cutaneous plasmacytosis was thought to be a reactive process with unknown etiology. Histologically, lesions contain dense perivascular infiltration of mature polyclonal plasma cells without any atypia, in the dermis and subcutaneous fat. The clinical course is chronic and benign without spontaneous remission. Available treatments for cutaneous plasmacytosis include psoralen ultraviolet A radiotherapy, systemic chemotherapy and intralesional steroid injection. The patient with cutaneous plasmacytosis in this report was treated with tacrolimus ointment and psoralen ultraviolet A.

Abstract
SummaryIt has been suggested that protamine sulfate is a poor antidote for the bleeding side-effeets of low molecular weight heparins (LMWHs) in vivo, since protamine sulfate does not completely neutralize the anti-factor Xa activity of LMWHs in vitro or ex vivo. Therefore, we performed experiments to compare directly the abilities of protamine sulfate to neutralize the anticoagulant activities of the LMWH, enoxaparine, and unfractionated heparin ex vivo, with its ability to neutralize the bleeding side-effeets of both compounds in vivo. Bleeding was measured as the amount of blood lost from 5 cuts made in rabbits ears before and after treatment with enoxaparine or unfractionated heparin ± protamine sulfate. Plasma anti-factor Xa and anti-thrombin activities ex vivo, were measured chromogenically. Doses of 400 and 1,500 anti-factor Xa U/kg of heparin and enoxaparine, respectively, were required to enhance blood loss to the same extent. Protamine sulfate completely neutralized blood loss induced by both compounds, but did not neutralize the anti-factor Xa nor antithrombin activities ex vivo. We conclude that protamine sulfate is an effective antidote for the bleeding side-effeets of enoxaparine and unfractionated heparin, despite its inability to completely neutralize their anticoagulant activities.

Abstract
This study was conducted to evaluate effects of rare earth element-enriched yeast (RY) on growth performance, nutrient digestibility, blood profile, and fecal microbial flora in finishing pigs. A total of 100 finishing pigs [(Landrace × Yorkshire) × Duroc] were used in a two-phase feeding trial. Pigs were randomly assigned to five treatments according to their initial body weight (five pens per treatment, two gilts and two barrows per pen). Treatments were basal diets, free of antibiotics [negative control (NC)]; NC + 500, 1000, and 1500 mg kg−1, respectively, of RY; antibiotics diets, NC + 500 mg kg−1 of tiamulin [positive control (PC)]. Overall, average daily gain (ADG) and gain to feed ratio (G:F) increased linearly with increasing level of RY in diets. At the end of the experiment, blood lymphocyte concentration and apparent total tract digestibility of dry matter and gross energy increased linearly in pigs fed the increasing level of RY in diets. The better ADG, G:F, and fecal Lactobacillus counts were observed in both RY and PC groups compared with the NC group. In conclusion, diets with RY improved growth performance, digestibility, blood lymphocyte counts, and fecal Lactobacillus counts in finishing pigs, and RY may be considered as an alternative to antibiotics.

Abstract
The present study aimed to investigate the mechanisms by which mannose protects the lung injury induced in rats with acute pancreatitis (AP). An AP combined with Acute Lung Injury (ALI) model was established. A total of 90 healthy adult male Sprague-Dawley rats (300±50g weight) were randomly divided into three groups: sham operation group (SO group), severe acute pancreatitis lung injury group (SAP group), and mannose intervention group (MT group). Subsequently, each group was divided into two subgroups based on the time passed from intervention, namely 6 and 12 h. Each subgroup comprised 15 rats. The ratio of wet/dry weight of the lung tissue exhibited no significant change at different time points in the SO group. This parameter was significantly increased in the SAP group compared with the SO group at each time point of the treatment (P less than 0.05) and it was significantly lower in the MT group than that in the AP group (P less than 0.05) and it was significantly increased in the AP group at each time (P less than 0.05) compared with the SO group. The levels of TNF-α in the lung tissue in the SO group exhibited no significant change at different time points, but they were significantly decreased in the MT group at each time point (P less than 0.05) compared with the SAP group. The mannose receptor (MR) mRNA and protein levels in the lung tissues exhibited no significant change at different time points. The mRNA and protein levels of MR in the SAP group were significantly decreased at each time point (P less than 0.05) compared with the SO group. The mRNA and protein levels of MR, in the lung tissue of the MT group were significantly increased at each time point compared with the SAP group (P less than 0.05). Mannose could reduce the injury caused to the lung tissue of rats with severe acute pancreatitis by up-regulation of the expression of MR mRNA and protein.

Abstract
OBJECTIVE Anterior cruciate ligament (ACL) injury initiates a cascade of events often leading to osteoarthritis (OA). ACL reconstruction does not alter the course of OA, suggesting that heightened OA risk is likely due to factors in addition to the joint instability. We showed that torn ACL remnants express periostin (POSTN) in the acute phase of injury. Considering that ACL injury predisposes to OA and that POSTN is associated with cartilage metabolism, we hypothesize that ACL injury affects chondrocytes via POSTN. DESIGN Cartilage was obtained from osteoarthritic patients and ACL remnants were collected from patients undergoing ACL reconstruction. Crosstalk between ACL remnants and chondrocytes was studied in a transwell co-culture system. Expression of POSTN and other anabolic and catabolic genes was assessed via real-time polymerase chain reaction (PCR). Immunostaining for periostin was performed in human and mouse cartilage. The impact of exogenous periostin and siRNA-mediated ablation of periostin on matrix metabolism and cell migration was examined. Furthermore, the effect of anabolic (transforming growth factor beta 1 [TGF-β1]) and catabolic (interleukin 1 beta [IL-1β]) factors on POSTN expression was investigated. RESULTS ACL remnants induced expression of POSTN, MMP13 and ADAMTS4. Periostin levels were significantly higher in osteoarthritic compared to normal cartilage. Exogenous periostin induced MMP13 expression and cell migration, and repressed COL1A1 expression while POSTN knockdown inhibited expression of both anabolic and catabolic genes and impeded cell migration. TGF-β1 and IL-1β treatment did not alter POSTN expression but influenced chondrocyte metabolism as determined by quantification of anabolic and catabolic genes via real-time PCR. CONCLUSIONS ACL remnants can exert paracrine effects on cartilage, altering cellular homeostasis. Over time, this metabolic imbalance could contribute to OA development.

Abstract
OBJECTIVE This study aimed to investigate the role of long non-coding RNA MEG3 (lncRNA MEG3) in osteosarcoma (OS) and further explore the underlying molecular mechanism. MATERIALS AND METHODS The expression profiles of MEG3 in OS cell lines and normal osteoblast cell line were detected by qRT-PCR. MEG3 was over-expressed in OS cell line by using LV-MEG3. MTT and colony-formation assays were applied for cell proliferation analysis. Cell migration assay was applied to investigate the cell migration ability. In addition, the expression levels of cell growth and metastasis related factors (Notch1, Hes1, TGF-β, N-cadheren and E-cadheren) were determined to illustrate the mechanisms. RESULTS We found that compared with normal osteoblast hFOB1.19 cell line, MEG3 was significantly down-regulated in MG63 and U2OS cell lines, particularly in MG-63 cells. MEG3 was significantly up-regulated in MG63 cells by LV-MEG3. Cell proliferation and migration ability were obviously repressed by MEG3 over-expression. In addition, MEG3 over-expression markedly inhibited Notch1, Hes1,TGF-β and N-cadheren expression, and the expression level of E-cadheren was improved. CONCLUSIONS These results indicated that MEG3 could prevent cell growth and metastasis of OS by repressing Notch and TGF-β signaling pathway, thus providing a potential therapeutic target for OS treatment (Tab. 1, Fig. 4, Ref. 30).

Abstract
OBJECTIVE To assess the impact of osteoarthritis (OA) on the meniscus by comparing transcripts and biological processes in the meniscus between patients with and without OA. DESIGN RNA microarrays were used to identify transcripts differentially expressed (DE) in meniscus obtained from 12 OA and 12 non-OA patients. The non-OA specimens were obtained at the time of arthroscopic partial meniscectomy. Real-time PCR was performed on selected transcripts. Biological processes and gene-networking was examined computationally. Transcriptome signatures were mapped with 37 OA-related transcripts to evaluate how meniscus gene expression relates to that of OA cartilage. RESULTS We identified 168 transcripts significantly DE between OA (75 elevated, 93 repressed) and non-OA samples (≥1.5-fold). Among these, CSN1S1, COL10A1, WIF1, and SPARCL1 were the most prominent transcripts elevated in OA meniscus, POSTN and VEGFA were most highly repressed in OA meniscus. Transcripts elevated in OA meniscus represented response to external stimuli, cell migration and cell localization while those repressed in OA meniscus represented histone deacetylase activity (related to epigenetics) and skeletal development. Numerous long non-coding RNAs (lncRNAs) were DE between the two groups. When segregated by OA-related transcripts, two distinct clustering patterns appeared: OA meniscus appeared to be more inflammatory while non-OA meniscus exhibited a "repair" phenotype. CONCLUSIONS Numerous transcripts with potential relevance to the pathogenesis of OA are DE in OA and non-OA meniscus. These data suggest an involvement of epigenetically regulated histone deacetylation in meniscus tears as well as expression of lncRNAs. Patient clustering based on transcripts related to OA in articular cartilage confirmed distinct phenotypes between injured (non-OA) and OA meniscus.

Abstract
PURPOSE OF THE STUDY This study was aimed to compare conventional surgery and surgery assisted by 3D-printing technology in the treatment of humeral intercondylar fractures. In addition, we also investigated the effect of 3D-printing technology on the communication between doctors and patients. MATERIAL AND METHODS A total of 91 patients with humeral intercondylar fracture were enrolled in the study from March 2013 to August 2015. They were divided into two groups: 43 cases of 3D-printing group, 48 cases of conventional group. The individual models were used to simulate the surgical procedures and carry out the surgery according to plan. Operation duration, blood loss volume, fluoroscopy times and time to fracture union were recorded. The final functional outcomes, including the motion of the elbow, MEPS and DASH were also evaluated. Besides, we made a simple questionnaire to verify the effectiveness of the 3D-printed model for both doctors and patients. RESULTS The operation duration, blood loss volume and fluoroscopy times for 3D-printing group was 76.6±7.9minutes, 231.1±18.1mL and 5.3±1.9 times, and for conventional group was 92.0±10.5minutes, 278.6±23.0mL and 8.7±2.7 times respectively. There was statistically significant difference between the conventional group and 3D-printing group (p<0.05). However, No significant difference was noted in the final functional outcomes between the two groups. Furthermore, the questionnaire showed that both doctors and patients exhibited high scores of overall satisfaction with the use of a 3D-printing model. DISCUSSIONS This study suggested the clinical feasibility of 3D-printing technology in treatment of humeral intercondylar fractures. LEVEL OF EVIDENCE Level II prospective randomized study.

BACKGROUND Pleiotropic cytokine interleukin-10 (IL-10) has been suggested as modifying risk for atherosclerosis. Promoter region genetic polymorphism of IL-10 gene is known to be associated with the level of IL-10 production. Through these effects, they might be involved with the ischemic stroke (IS). Our aim was to assess the nature of the functional polymorphisms in IL-10 promoter and any links with IS in Chinese Han population. METHODS The IL-10 -1082 G>A, -819 C>T and -592 C>A functional polymorphisms were determined by TaqMan SNP Genotyping assays in 1296 subjects (648 IS patients diagnosed by CTs or/and magnetic resonance imaging (MRI) and 648 normal healthy controls from Chinese Han Population). Multivariate logistic regression analysis was used to show the association between the IL-10 genotypes and the IS events. RESULTS We found that the CC genotype of -819 C>T was more common in controls than IS subjects (P<0.05, corrected for multiple testing) in the Han population. CC carriage may be associated with the decreased risk of IS in the Han ethnic group (OR 0.65, 95% CI 0.43-0.97). In addition, the CC genotype in -592 C>A and GG genotype in -1082 G>A are all extremely low in Chinese Han cases and controls. CONCLUSIONS The G allele frequency at the -1082 promoter region of IL-10 was rare in Chinese Han population which are diffierent from American/European populations.. IL-10 -819 C>T may be an independent protective factor for IS in the Chinese Han population.

Abstract
Species of Nigrospora commonly occur as plant pathogens, endophytes or saprobes, and have been shown to be extremely interesting for the discovery of novel metabolites. The familial placement, as well as phylogenetic relationships among Nigrospora species remain ambiguous. In this study, Nigrospora (= Khusia) is confirmed as a monophyletic genus belonging to Apiosporaceae (Xylariales), based on a phylogeny inferred from LSU sequence data. A multi-locus phylogeny based on ITS, TEF1-α and TUB2, in conjunction with morphological characters, host associations, and ecological data was employed for species delimitation in Nigrospora, as well as identification of 165 recently collected isolates from China, and three from Europe. In total 13 novelties are proposed including 12 new species and 1 new combination. Five species are re-described based on an examination of type specimens and/or fresh collections. New species described in this paper include: N. aurantiaca, N. bambusae, N. camelliae-sinensis, N. chinensis, N. guilinensis, N. hainanensis, N. lacticolonia, N. osmanthi, N. pyriformis, N. rubi, N. vesicularis and N. zimmermanii. Furthermore, N. vietnamensis is transferred to Arthrinium. Our results indicate a high level of species diversity within Nigrospora, with a general lack in host specificity. Taxa that cluster basal in Nigrospora have wide host ranges, whereas those that diverged later tend to have narrow host ranges. The currently available data suggest, therefore, that the general evolutionary direction in the genus Nigrospora is from a wide to a narrow host range.

Abstract
Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014-2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 116 genera, while 23.5 % were not identified to species level. Among these species, 85.8 % (211 species) belonged to Ascomycota; 7.3 % (18 species) belonged to Basidiomycota; 6.9 % (17 species) belonged to Mucoromycotina. The majority of these species have been previously known from other environments, mostly from plants or animals as pathogens, endophytes or via a mycorrhizal association. We also found that 59 % of these species were discovered for the first time from Karst caves, including 20 new species that are described in this paper. The phylogenetic tree based on LSU sequences revealed 20 new species were distributed in six different orders. In addition, ITS or multi-locus sequences were employed to infer the phylogenetic relationships of new taxa with closely related allies. We conclude that Karst caves encompass a high fungal diversity, including a number of previously unknown species. Novel species described include: Amphichorda guana, Auxarthronopsis guizhouensis, Biscogniauxia petrensis, Cladorrhinum globisporum, Collariella quadrum, Gymnoascus exasperatus, Humicola limonisporum, Metapochonia variabilis, Microascus anfractus, Microascus globulosus, Microdochium chrysanthemoides, Paracremonium variiforme, Pectinotrichum chinense, Phaeosphaeria fusispora, Ramophialophora globispora, Ramophialophora petraea, Scopulariopsis crassa, Simplicillium calcicola, Volutella aeria, and Wardomycopsis longicatenata.

Abstract
A novel disease characterized by small brown-black spots (1 to 2 mm in diameter) on tender tea leaves (Camellia sinensis) has been observed in many regions of Hubei Province, China, which severely affects the yield and quality of tea. Tea leaf samples with typical symptoms were collected from three major tea-cultivation regions of Hubei, and were subjected to pathogen isolation for etiological analysis. As a result, 34 Pestalotiopsis isolates were obtained from 20 samples, and they were identified as Pestalotiopsis theae (14 isolates), P. camelliae (12), and P. clavispora (8), determined by morphologies and phylogenetic analysis based on internal transcribed spacer, and partial β-tubulin and translation elongation factor 1-alpha genes. Pathogenicity tests on detached tea leaves showed that no matter what mycelial discs or conidium suspensions were used, inoculation of the Pestalotiopsis fungi could result in small brown-black spots (1 to 2 mm in diameter) on wounded leaves, similar to those observed in the field in the sizes and colors. It also revealed that only P. theae had pathogenicity on unwounded tea leaves, and P. theae and P. clavispora showed significantly higher virulence than P. camelliae. Inoculation test with conidium suspension on intact tea leaves in the field further confirmed that P. theae as the pathogen of brown-black spots. Reisolation of the pathogens from diseased leaves confirmed that the symptom was caused by the inoculation of Pestalotiopsis fungi. The P. theae isolates responsible for brown-black spots were also compared with those for tea gray blight disease in growth rate, pathogenicity, and molecular characteristics in parallel. To our knowledge, this is the first report that the Pestalotiopsis fungi cause brown-black spot disease on tender tea leaves. The results provide important implications for the prevention and management of this economically important disease.

Abstract
Objective: To observe the outcome of breast reconstruction with autologous fat grafting in the patients following treatment for breast cancer. Methods: The clinical data of 22 patients after breast cancer modified radical mastectomy with fat grafting for breast reconstruction from January 2012 to March 2015 at Department of Body Contouring and Liposuction Center of Plastic Surgery, Hospital of Peking Union Medical College were analyzed retrospectively. The age of 22 patients (all female) was 28 to 54 years. Fifteen patients were performed breast modified radical mastectomy 5 to 16 year ago without radiotherapy, 7 patients were performed breast modified radical mastectomy following regular radiotherapy 2 years ago. Low negative pressure liposuction technical was applied to harvest fat tissue for 400 to 800 ml which was filtrated and purified by cotton pad method in low temperature environment. Fat grafting was performed with multi-level and multi-tunnel and in multi-point injection ways. All patients were followed up by regular imaging evaluation with MRI or ultrasonography after operation every 3 months. Results: All breast reconstruction were successfully performed in 22 patients, no severe complications occurred. Among 15 patients without radiotherapy, 12 patients were performed with autologous fat grafting for breast reconstruction, 3 patients with prosthetic implantation for breast augmentation after autologous fat grafting. Among 7 patients with radiotherapy, 6 patients were performed with autologous fat grafting for breast reconstruction, 1 patient with prosthetic implantation for breast augmentation after autologous fat grafting. The volume of fat grafting was 104 to 380 ml. It took 2.5 hours to finish the operation including 1.0 to 1.5 hours for liposuction and 40 minutes for fat grafting. Next fat grafting were performed after 3 months. The fat of the breast were survived well detecting by MRI, only 1 patient had a cystic nodule which had been resected during nipple reconstruction. Ultrasonography screened several cystic nodules with the major axis of 0.1 to 0.2 cm in the breast, which couldn't be found by palpating in 18 patients. The patients were followed up for 18 to 36 months, the outcome were satisfactory. Conclusion: Autologous fat grafting for breast reconstruction simplifies the operation program with satisfied results and avoids the complications of breast reconstruction with skin flap.

Abstract
OBJECTIVE To assess the diagnostic rate, safety and clinical application of percutaneous renal masses biopsy for advanced renal cell carcinoma patients. METHODS In this retrospective study, we collected the data of renal masses from the patients who underwent renal masses biopsy under ultrasound from April 2001 to December 2014 in Peking University First Hospital. A total of 75 patients who were undiagnosed or diagnosed with advanced renal cell carcinoma by the imageological method were enrolled in this study. The patient and lesion characteristics such as tumor size, pathology of tumor, histologic subtype, pathological grade, biopsied location and biopsied cores were recorded and analyzed. RESULTS Among all the 75 patients, biopsy was diagnostic in 64 cases (85.3%) and non-diagnostic in 11 cases (14.7%). Of the 64 diagnostic biopsies, 60 were malignant, including 37 (61.7%) renal cell carcinoma (RCC), 13 (21.7%) urothelial carcinoma and 10 (16.7%) other malignant masses. Of all the RCC subjects, 24 suffered from clear cell RCC, 5 papillary RCC, 3 collecting duct carcinomas, 1 unclassified RCC and 4 unknown subtypes. The 11 non-diagnostic biopsied samplings included inflammatory, blood and extrarenal tissue and normal renal tissue. The proportion of collecting duct carcinoma in RCC was 10.8% and the proportion of squamous carcinoma in urothelial carcinoma was 23.1%, which were both higher than the previous research findings. For the male and female groups, non-diagnostic yields were 6.5% and 30.4%, respectively (P=0.022). Of all the 75 patients, 13 renal cell carcinoma patients underwent the surgical treatment and got the results of postoperative pathology. Comparing preoperative biopsy pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rates for benign and malignant lesions, pathological subtype and pathological grade were 100%, 81.8% and 60%, respectively. Mild macroscopic hematuria occurred in 1 case after RMB and there were no serious complications in all the cases. CONCLUSION Percutaneous renal masses biopsy under ultrasound with a high diagnostic rate which can define the histologic subtype of renal cell carcinoma. With targeted therapy, more and more patients whose evaluation suggests local advanced disease or metastatic tumors adopt renal tumor biopsy to define the histologic subtype, which could avoid unnecessary surgical treatment.

Abstract
OBJECTIVE To analyze the clinical pathologic characteristics of cases with fluorescence in situ hybridization (FISH) positive of exfoliated urothelial cells, so as to evaluate the clinical utility of FISH in the diagnosis of urothelial carcinoma (UC). METHODS A total of 271 cases of FISH positive in Department of Urology of Peking University First Hospital from Apr. 2012 to Sep. 2015 were recruited in this study. Retrospective analysis was made on their clinical data. For FISH analysis, labeled probes specific for chromosomes 3, 7, 17, and the p16 (9p21) gene were used to assess chromosomal abnormalities indicative of malignancy. The positive predict values (PPV) of all the techniques were analyzed. RESULTS Of the 271 patients, 207 cases were UC, 7 cases were non-UC, and 57 cases were benign diseases. The PPV of FISH in detecting UC was 76.4%, while the 95% confidence interval (CI) 71.3% to 81.5%. In the cohort of FISH positive, this value was similar to that of urinary cytology (PPV 86.8%, 95% CI: 78.5%-95.0%). The PPV of FISH was lower than that of cystoscopy and ureteroscopy (PPV 96.1%, 95% CI: 91.7%-100.0%). There were significant differences between this study and the PPV of FISH reported abroad (PPV 53.9%, χ2=33.048, P<0.001). Of all the UC with FISH positive, bladder cancer showed an earlier pathological stage versus renal pelvic carcinoma and ureteral carcinoma, with significance (χ2=5.894, P=0.015, and χ2=13.601, P<0.001, respectively). However, no difference was found in the size, pathological stage and pathological grade of tumors between the urinary cytology positive group and the urinary cytology negative group. The rate of high-grade UC in ureteral carcinoma of FISH positive was 92.3%, much higher than that of ureteral carcinoma reported domestically. CONCLUSION The PPV of FISH in detecting UC is higher relatively, with a better clinic value for Chinese patients. The ureteral carcinoma with FISH positive obtains a higher pathological grade, which is of great guiding significance for UC.

Abstract
Objective: To investigate the effects between fish, seafood and pickled food intakes on oral squamous cell carcinoma (OSCC). Methods: A case-control study was carried out in Fujian area during September 2010 to December 2016, in which 604 newly diagnosed primary OSCC cases confirmed by pathological diagnosis were collected from hospital and 1 343 control subjects were enrolled from community and healthy hospital population. Demographic data, history of smoking drinking and tea drinking, oral hygiene status and dietary behaviors (fish, seafood and pickled food intakes) were collected by in-person interviews using a standard questionnaire.Using unconditional logistic regression to estimate adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CIs) to assess the effects of fish, seafood and pickled food intakes on OSCC. Analysis stratified by smoking, alcohol drinking and bad prosthesis to explore the possible difference in association between subgroups. Multiplicative interactions and additive interactions between fish and bad prosthesis, seafood and alcohol drinking, pickled food and bad prosthesis were assessed by unconditional logistic regression, relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP) and synergy index (S). Results: The average age of case group and control group were separately (58.69±13.92) years old and (59.27±11.37) years old (χ(2)=4.75, P=0.191). The people whose fish and seafood intakes ≥3 times/week had the lower risk of OSCC, the adjusted OR (95%CI) values were 0.63 (0.52-0.77) and 0.51 (0.41-0.64); The stratified analysis indicated that the people having bad prosthesis had the lower risk of OSCC if they eating fish ≥3 times/week, and the adjusted OR (95%CI) values was 0.53 (0.39-0.71); the people having bad prosthesis had the higher risk of OSCC if they eating pickled food ≥3 times/week, the adjusted OR (95%CI) values was 1.37 (1.02-1.88). Regularly eating seafood can decrease the risk of OSCC for non-smokers, smokers, non-drinkers, drinkers, people without bad prosthesis and had bad prosthesis, the adjusted OR (95%CI) values were 0.49 (0.36-0.68), 0.52 (0.37-0.73), 0.41 (0.31-0.55), 0.77 (0.51-0.96), 0.49 (0.36-0.67), 0.59 (0.42-0.83). Crossover analysis showed fish and bad prosthesis exist multiplication interaction relationship (adjusted OR=0.66, 95%CI: 0.44-0.97) and additional interaction relationship (RERI=-0.81, 95%CI:-1.43--0.19; AP=-0.76, 95%CI:-1.35--0.17; S=0.08, 95%CI: 0.01-0.98); pickled food and bad prosthesis exist multiplication interaction relationship (adjusted OR=1.63, 95%CI: 1.06-2.51) and addition interaction relationship (RERI=0.65, 95%CI:0.08-1.22; AP=0.36, 95%CI:0.10-0.62; S=5.19, 95%CI:1.32-54.49). Conclusion: Reducing the consumption of pickled food, quitting smoking and limiting alcohol consumption, and regularly eating fish and seafood can prevent the occurrence of OSCC.

Abstract
Many schizophrenia susceptibility loci have been identified through genome-wide association studies (GWASs) in European populations. However, until recently, schizophrenia GWASs in non-European populations were limited to small sample sizes and have yielded few loci associated with schizophrenia. To identify genetic risk variations for schizophrenia in the Han Chinese population, we performed a two-stage GWAS of schizophrenia comprising 4384 cases and 5770 controls, followed by independent replications of 13 single-nucleotide polymorphisms in an additional 4339 schizophrenia cases and 7043 controls of Han Chinese ancestry. Furthermore, we conducted additional analyses based on the results in the discovery stage. The combined analysis confirmed evidence of genome-wide significant associations in the Han Chinese population for three loci, at 2p16.1 (rs1051061, in an exon of VRK2, P=1.14 × 10-12, odds ratio (OR)=1.17), 6p22.1 (rs115070292 in an intron of GABBR1, P=4.96 × 10-10, OR=0.77) and 10q24.32 (rs10883795 in an intron of AS3MT, P=7.94 × 10-10, OR=0.87; rs10883765 at an intron of ARL3, P=3.06 × 10-9, OR=0.87). The polygenic risk score based on Psychiatric Genomics Consortium schizophrenia GWAS data modestly predicted case-control status in the Chinese population (Nagelkerke R2: 1.7% ~5.7%). Our pathway analysis suggested that neurological biological pathways such as GABAergic signaling, dopaminergic signaling, cell adhesion molecules and myelination pathways are involved in schizophrenia. These findings provide new insights into the pathogenesis of schizophrenia in the Han Chinese population. Further studies are needed to establish the biological context and potential clinical utility of these findings.

Abstract
The aim of this study was to evaluate the therapeutic effect of rhubarb extract on acute pancreatitis. Ninety-six healthy Sprague Dawley rats, weighing 301±5.12 g were randomly divided into 4 groups: sham surgery (group A), acute pancreatitis model (group B), acute pancreatitis with normal saline (group C), and acute pancreatitis model with rhubarb (group D). The levels of serum amylase (AMY) and TNF-α were measured at 1st, 6th, 12th and 24th hour after modeling, and the pancreatic tissue were used to observe the pathologic changes. Compared to the sham group, the serum AMY and serum tumor necrosis factor (TNF-α) levels were significantly increased in the other groups (p <0.05). Compared to the model group and the saline group, the serum AMY, serum TNF-α level and pathological changes of rats in the rhubarb group were significantly lower (p <0.05). The serum AMY and TNF-α levels increased in acute pancreatitis. The rhubarb reduced the serum AMY and TNF-α level in rats with acute pancreatitis and reduced the pathological changes of pancreas and other tissues.

Abstract
Objective: To observe the senescent effect of human pulmonary arterial endothelial cells (HPAEC) stimulated by cigarette smoke extract (CSE) and the effect of secretion of senescent cells on human pulmonary arterial smooth muscles cell (HPASMC) proliferation and migration. Methods: HPAEC was treated with different concentrations of CSE in vitro and cell proliferation was determined by CCK8, senescence cells analyzed by detecting the β-gal activity, and the senescent proteins of cells measured by Western blot. The concentration of senescence-associated secretory phenotype (SASP) was detected by ELISA and the expression of MCP-1 and TGF-β1 was measured by Real-time PCR. The number of the proliferated cells was measured by Transwell assay and immunoflurescence. Results: The HPAEC was aging with the stimulation concentration of CSE increasing and the stimulation time prolonging (P<0.05). Western blot indicated that the senescent associated protein p53 or p21 increased markedly after 48 h and 72 h CSE-exposure (n=3, P<0.05). The SA-β-Gal staining showed that the number of senescent cells increased as the exposure time prolonged. Compared with the control group, cell viability of 48 h group(1.8±0.1) and 72 h group (1.8±0.1) decreased significantly. The flow cytometry showed a significant difference between the CSE group(14.1±1.2) and the control group(28.5±1.8) in S phase(P<0.01), indicating cell cycle arrest. The SASP was increasing as the CSE-exposure prolonged. Compared with the control group(177±39), the 48 h group(460±43) and the 72 h group(609±64) showed a marked increase in MCP-1(P<0.05). For TGF-β1, it had a same tendency and a significant difference between the control group(121±18) and the 48 h group(413±32) or 72 h group(606±67, both P<0.05). In the meantime, the bFGF increased after 48 h stimulation(291±13, P<0.05). Besides MCP-1, TGF-β1 showed a significant difference between the control group and the 72 h CSE-exposure group (P<0.01). Premature cells could secrete SASP which induced HPASMC proliferation. After different times of conditioned medium stimulation, HPASMC proliferated especially at 72 h(P<0.05) . The immnoflorescence and Transwell assay confirmed this finding. Conclusion: CSE could induce senescence of HPAEC and SASP production which improved HPASMC proliferation and migration.

Abstract
The Didymellaceae is one of the most species-rich families in the fungal kingdom, and includes species that inhabit a wide range of ecosystems. The taxonomy of Didymellaceae has recently been revised on the basis of multi-locus DNA sequence data. In the present study, we investigated 108 Didymellaceae isolates newly obtained from 40 host plant species in 27 plant families, and various substrates from caves, including air, water and carbonatite, originating from Argentina, Australia, Canada, China, Hungary, Israel, Italy, Japan, South Africa, the Netherlands, the USA and former Yugoslavia. Among these, 68 isolates representing 32 new taxa are recognised based on the multi-locus phylogeny using sequences of LSU, ITS, rpb2 and tub2, and morphological differences. Within the Didymellaceae, five genera appeared to be limited to specific host families, with other genera having broader host ranges. In total 19 genera are recognised in the family, with Heracleicola being reduced to synonymy under Ascochyta. This study has significantly improved our understanding on the distribution and biodiversity of Didymellaceae, although the placement of several genera still need to be clarified.

Abstract
The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), is a worldwide pest of stored grains. Using "Y"-tube olfactometry we studied the response of T. castaneum to odors from simulated wheat infestations containing conspecifics, and infestations containing the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), and the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae). Tribolium castaneum larvae were significantly attracted to odors from all three test species. Tribolium castaneum adults were attracted to grains infested by R. dominica and flour infested by T. castaneum but repelled from grains infested by S. granarius. Further behavioral analysis with pheromones showed that T. castaneum were significantly attracted to their aggregation pheromone, dimethyldecanal (DMD), but not to the R. dominica aggregation pheromone, a mixture of dominicalure 1 and 2. Female T. castaneum adults were attracted to ∼50-fold less DMD than larvae and 100-fold less than male adults, suggesting they are more sensitive to DMD. This study improves our understanding of T. castaneum behaviors to infested grain volatile compounds and pheromones, and may help develop new control methods for grain pest species.

Abstract
Anthracnose caused by Colletotrichum species is a serious disease of more than 30 plant genera. Several Colletotrichum species have been reported to infect chili in different countries. Although China is the largest chili-producing country, little is known about the species that have been infecting chili locally. Therefore, we collected samples of diseased chili from 29 provinces of China, from which 1285 strains were isolated. The morphological characters of all strains were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT, CAL, CHS-1, GAPDH, TUB2, and HIS3) were performed on selected representative strains. Fifteen Colletotrichum species were identified, with C. fioriniae, C. fructicola, C. gloeosporioides, C. scovillei, and C. truncatum being prevalent. Three new species, C. conoides, C. grossum, and C. liaoningense, were recognised and described in this paper. Colletotrichum aenigma, C. cliviae, C. endophytica, C. hymenocallidis, C. incanum, C. karstii, and C. viniferum were reported for the first time from chili. Pathogenicity of all species isolated from chili was confirmed, except for C. endophytica. The current study improves the understanding of species causing anthracnose on chili and provides useful information for the effective control of the disease in China.

Methods: Twenty-four consecutive patients with synchronous renal cell carcinoma and urothelial carcinoma treated in our center from March 2005 to December 2015 were retrospectively reviewed. Their clinical, pathological and prognostic features were evaluated. Kaplan-Meier curves were used to estimate overall survival. Results: Patient' age was range from 48 to 79 yrs (median 69.5). Fourteen patients presented with macroscopic hematuria, and 10 patients were asymptomatic. B-ultrasound, computed tomography (CT) and cystoscopy initially indicated renal cell carcinoma concurrent with ipsilateral upper urinary tract urothelial carcinoma (UTUC) in 4 cases, renal cell carcinoma concurrent with bladder tumor in 16 cases, renal cell carcinoma concurrent with both ipsilateral UTUC and bladder tumor in 1 case, renal cell carcinoma in 2 cases and ureter carcinoma in 1 case. Different treatments were performed. The median follow-up time after surgery was 22.5 months. For patients with synchronous renal cell carcinoma and bladder tumor, there was no significant survival difference between patients treated with partial nephrectomy or radical nephrectomy. During follow up, 3 patients died of renal cell carcinoma, 3 patients died of non-oncological disease and 1 patient died of ureter carcinoma. The 3-year overall survival rate was 82.7%. For patients with synchronous renal cell carcinoma and bladder tumor, there was no significant survival difference between patients treated with partial nephrectomy or radical nephrectomy (P=0.874). Conclusions: Concurrence of renal cell carcinoma and urothelial carcinoma is clinically rare. Treatments should be individualized. The prognosis for a patient with synchronous renal cell carcinoma and urothelial carcinoma is associated with the more aggressive one.

Abstract
Objective: To investigate the possibility of heart rate as an optimum index for evaluating physical labor intensity. Methods: From September to October, 2015, a total of 111 male young adults were selected as study subjects. A cycle ergometer was used for exercise at different intensities (20, 40, 60, 80, 100, 120, 140, 160, and 180 W) , and the exercise at each intensity lasted for 6 minutes. The subjects wore the K4b2 portable cardiopulmonary function testing instrument for the real-time monitoring of heart rate (HR) , pulmonary ventilation volume (Ve) , oxygen consumption (VO(2)) , and energy metabolic rate (E) . The origin software was used for correlation and regression analyses of HR, Ve, VO(2), and E collected at different intensities to establish Ve-HR, VO(2)-HR, and E-HR regression equations. Results: At different intensities, HR was positively correlated with Ve, VO(2), and E (r=0.8985, 0.8733, and 0.8973, all P<0.01) . There was a significant difference in the R(2) value of Ve-HR, VO(2)-HR, and E-HR regression equations (R(2)=0.8070, 0.7625, and 0.8049, all P <0.01) . The validation results showed that there was no significant difference between the calculated values and the measured ones (P>0.05) . Conclusion: HR can replace Ve, VO(2), and E and be used as an optimum index for evaluating physical labor intensity.

Abstract
Genera of Phytopathogenic Fungi (GOPHY) is introduced as a new series of publications in order to provide a stable platform for the taxonomy of phytopathogenic fungi. This first paper focuses on 21 genera of phytopathogenic fungi: Bipolaris, Boeremia, Calonectria, Ceratocystis, Cladosporium, Colletotrichum, Coniella, Curvularia, Monilinia, Neofabraea, Neofusicoccum, Pilidium, Pleiochaeta, Plenodomus, Protostegia, Pseudopyricularia, Puccinia, Saccharata, Thyrostroma, Venturia and Wilsonomyces. For each genus, a morphological description and information about its pathology, distribution, hosts and disease symptoms are provided. In addition, this information is linked to primary and secondary DNA barcodes of the presently accepted species, and relevant literature. Moreover, several novelties are introduced, i.e. new genera, species and combinations, and neo-, lecto- and epitypes designated to provide a stable taxonomy. This first paper includes one new genus, 26 new species, ten new combinations, and four typifications of older names.

Abstract
Abstract
Background:Insufficient data exist to describe the hematological safety of palbociclib in African American women (AAW) who are known to have a high incidence of benign ethnic neutropenia (BEN). The studies that led to the FDA approval of palbociclib (PALOMA 1 and 3) only included participants with baseline absolute neutrophil count (ANC) of ≥1500/mm3. The standard lower limit of ANC of 1500/mm3 for initiation of treatment in those with BEN has been previously challenged. In this current study, we propose to lower the ANC cutoff for enrollment to 1000/mm3.
Trial design: PALINA is a phase II study evaluating the hematological safety of palbociclib with letrozole in 35 AAW with hormone receptor (HR) positive HER2 negative advanced breast cancer and ANC ≥1000/mm3. Patients enrolled will receive palbociclib 125mg daily for 21 days followed by 7 days off and letrozole 2.5mg daily. For patients enrolled with baseline ANC between 1000-1499/mm3, initial dose of palbociclib will be 100mg daily for 21 days followed by 7 days off. Presence of Duffy Null Polymorphism (SNP rs2814778) as a predictive marker for neutrophil count will be assessed at baseline. Metabolite and exosomal signature (proteins and RNA) of drug resistance will be evaluated at different time points.
Main eligibility criteria: Self-identified Black, African or AAW of ≥ 18 years of age with proven diagnosis of advanced HR-positive, HER2-negative breast cancer; ECOG performance status 0-2; ANC ≥ 1,000/mm3 and no prior receipt of CDK4/6 inhibitors.
Specific aims: The primary endpoint is the proportion of patients who complete planned oncologic therapy without the development of a hematological event defined as episodes of febrile neutropenia and treatment discontinuation due to neutropenia. Additional endpoints include: number of patients who required dose delays or dose reductions in palbociclib attributed to neutropenia; rate of grade 3/4 neutropenia; clinical benefit rate at 24 weeks; correlations between metabolite and exosomal signature with disease response; correlations between baseline ANC prior to cancer diagnosis and the Duffy Null polymorphism with hematological safety.
Statistical methods: The study is designed to assess the rate of completion of planned therapy in the absence of a hematological event defined as episodes of febrile neutropenia and treatment discontinuation due to neutropenia. Simon's two-stage design with a maximum of 35 patients is used. The null hypothesis that the true completion rate is 60% will be tested against a one-sided alternative. This design yields a type I error rate of 0.05 and power of 80% when the true completion rate is 80%.
Present accrual and target accrual: The Institutional Review Board at Georgetown University Medical Center (GUMC) has approved the study. Enrollment of the first patient is expected in July 2016 with a total of 35 patients planned to be recruited. The recruitment sites are MedStar Georgetown University Hospital and other hospitals of the Georgetown MedStar Cancer Network, Hackensack University Medical Center and University of Alabama at Birmingham. This trial is funded by an ASPIRE Breast Cancer Research Award from Pfizer.

Abstract
Abstract
Introduction: Although only about 5-7% of breast cancers occur in women under 40 years of age, multiple studies have shown that these cancers are more aggressive. In addition issues related to genetic testing and fertility preservation are of particular importance for AYA patients with breast cancer. This retrospective analysis aims to describe various biologic and treatment related factors of an urban AYA population with breast cancer and the differences amongst these factors stratified by African American (AA) versus non-AA race. We will look at factors including stage at diagnosis, hormone receptor status, prevalence of BRCA1/2 mutations, time from diagnosis to treatment, enrollment in clinical trials, and fertility preservation.
Methods: A retrospective study of a population of AYA women with breast cancer seen at two hospitals in Washington D.C. from 2006 to 2015 was performed. Data was collected on age, BRCA1/2 test results, stage at diagnosis, hormone receptor status, time from diagnosis to treatment, enrollment in clinical trial, fertility preservation, and pregnant or breastfeeding status at time of diagnosis. Fisher exact test was used to test the association between two categorical variables. Wilcoxon rank sum test was used to compare time to treatment and stage at presentation between AA and non-AA patients.
Results: A total of 161 AYA patients were evaluated. 54 were identified as AA and 107 as non-AA (88 Caucasians, 13 Asian, 6 Hispanics). Median age was 32 years (20-39) overall; 32 years (23-39) for AA and 33 years (20-39) for non-AA. While the rate of genetic testing was high, significantly fewer AA AYA underwent testing compared to non-AA (74% versus 87% respectively, (p=0.050)) and 10% of AA versus 22% of non-AA were found to have a BRCA1/2 deleterious mutation (p=NS). Clinical trial participation was lower for AA compared to non-AA (57% vs. 76%, p=NS) for those where clinical trials were discussed/offered. Fertility preservation was pursued by 10% of AA vs. 35% of non-AA (p=0.001). Of note, 61% of AA and 34% of non-AA had children at the time of diagnosis (p=0.001). While AA (31%) presented more often with advanced stages of cancer compared to non-AA (19%) this was not statistically significant. Triple negativity was similar in AA AYA (25%) vs. non-AA (22%). The median time to treatment initiation did not vary between AA and non-AA (37 days vs. 36 days, p=NS).
Conclusion: In this retrospective study of an urban population of AYA women with breast cancer, there were no delays in treatment initiation or significant differences between AA and non-AA. When compared to non-AA, AA had a statistically significant lower rate of genetic testing and fertility preservation, although the latest could have been affected by a higher number of nulliparous in non-AA. . Encouragingly, the clinical trial participation of AYA who had previously discussed clinical trials with their physician was very high.

Abstract
Objective: To analyze the effect of gender on the prognosis of patients with non-small cell lung cancer (NSCLC). Methods: Data of 1 195 patients with NSCLC were analyzed by Chi-square, Kaplan-Meier, log-rank tests and Cox regression models. Results: Women had a longer survival than men (median overall survival 31.64 versus 22.71 months, P<0.01) in the participants of this study. Differences seen in overall survival remained the similar, after stratified by age, pathologic types, clinical stage, sizes, pleural effusion and surgery of the patients, respectively. Data from the multivariate analysis revealed that factors as smoking, clinical stage, metastatic when diagnosis was made and surgery, but not gender, were independent prognostic factors for patients with NSCLC. After adjustment for potential confounders, we found that smoking was a major confounding factor, affecting the relationship between gender and prognosis of NSCLC. Conclusion: Gender did not seem an independent prognostic factor for NSCLC patients while the survival advantages of females might be attributed to the lower prevalence of smoking in this population.

Abstract
BACKGROUND/OBJECTIVES Epidemiological results on the association between tea consumption and oral cancer remain controversial. We aimed to evaluate the exact relationship between tea consumption and oral cancer in Chinese population. SUBJECTS/METHODS A large-scale case-control study was conducted on 586 oral cancer patients and 1024 controls frequency-matched by age and gender. Epidemiological data were collected through face-to-face interviews with a structure questionnaire. Unconditional logistic regression model was used to assess the effect of tea consumption on oral cancer stratified by smoking, alcohol drinking and demographics. Quantity of tea consumed (ml/day) was categorized into five subgroups based on quartiles and then its interactions was evaluated with tobacco smoking and alcohol drinking at each subgroup. RESULTS Tea consumption showed an inverse association with oral cancer for non-smokers or non-alcohol drinkers (the odds ratios (ORs) were 0.610 (95% confidence interval (CI): 0.425-0.876) and 0.686 (95% CI: 0.503-0.934), respectively). For smokers or alcohol drinkers, decreased risk was only observed in those who consumed >800 ml/day. Furthermore, oolong tea consumption was associated with decreased risk of oral cancer in smokers or alcohol drinkers but not in non-smokers or non-alcohol drinkers. Tea consumption combined with smoking or/and alcohol drinking had a greater risk than tea consumption alone, but the risk was roughly reduced from zero to Q4 (>800 ml/day). Additionally, when stratified by demographics, the protective effect of tea was especially evident in females, urban residents, normal body mass index population (18.5-23.9), farmers, office workers and those aged <60 years. CONCLUSIONS Tea consumption protects against oral cancer in non-smokers or non-alcohol drinkers, but this effect may be obscured in smokers or alcohol drinkers. Additionally, demographics may modify the association between tea consumption and oral cancer.

Abstract
Insulin resistance and β-cell function are different between the young and elderly diabetes individuals, which are not well elaborated in the nondiabetic persons. The aims of this study were to compare insulin resistance and β-cell function between young and old adults from normal glucose tolerance (NGT) to prediabetes [which was subdivided into isolated impaired fasting glucose (i-IFG), isolated impaired glucose tolerance (i-IGT), and a combination of both (IFG/IGT)], and compare the prevalence of diabetes mellitus (DM) in the above prediabetes subgroups between different age groups after 3 years. A total of 1 374 subjects aged below 40 or above 60 years old with NGT or prediabetes were finally included in this study. Insulin resistance and β-cell function from homeostasis model assessment (HOMA) and interactive, 24-variable homeostatic model of assessment (iHOMA2) were compared between different age groups. The rate of transition to diabetes between different age groups in all pre-diabetes subgroups was also compared. Compared with the old groups, young i-IFG and IFG/IGT groups exhibit higher log HOMA-IR and log HOMA2-S, whereas the young i-IGT groups experienced comparable log HOMA-IR and log HOMA2-S when compared with old i-IFG and IFG/IGT groups. Three prediabetes subgroups all had similar log HOMA-B and log HOMA2-B between different age groups. In addition, the prevalence of diabetes in young i-IFG was statistically higher than that in old i-IFG after 3 years. Age is negatively related to log HOMA2-B in both age groups. Considering an age-related deterioration of β-cell function, young i-IFG, young i-IGT, and young IFG/IGT all suffered a greater impairment in insulin secretion than the old groups. Young i-IFG and IFG/IGT have more severe insulin resistance than the old groups. In addition, young i-IFG characterized with a higher incidence of DM than the old i-IFG. These disparities highlight that the prevention to slow progression from prediabetes to type 2 diabetes should be additionally focused in young prediabetes individuals, especially young i-IFG.

Abstract
This paper presents the design and preliminary evaluation of small-pixel CdTe gamma ray detectors equipped with a hybrid pixel-waveform (HPWF) readout system for gamma ray imaging applications with additional discussion on CZT due to its similarity. The HPWF readout system utilizes a pixelated anode readout circuitry which is designed to only provide the pixel address. This readout circuitry works in coincidence with a high-speed digitizer to sample the cathode waveform which provides the energy, timing, and depth-of-interaction (DOI) information. This work focuses on the developed and experimentally evaluated prototype HPWF-CdTe detectors with a custom CMOS pixel-ASIC to readout small anode pixels of 350 μm in size, and a discrete waveform sampling circuitry to digitize the signal waveform induced on the large cathode. The intrinsic timing, energy, and spatial resolution were experimentally evaluated in this paper in conjunction with methods for depth of interaction (DOI) partitioning of the CdTe crystal. While the experimental studies discussed in this paper are primarily for evaluating HPWF detectors for small animal PET imaging, these detectors could find their applications for ultrahigh-resolution SPECT and other imaging modalities.

Abstract
Although several cloned pigs have been successfully produced, the developmental competence of cloned embryos in vitro is still very low. Granulocyte colony-stimulating factor receptor (G-CSFR) was founded in the human trophoblastic cell line that is implicated in regulation and proliferation of trophoblast. In the present study, the somatic cell NT embryos derived from oocytes that have more than 3 cumulus cells layer were cultured and supplemented with various concentrations of hrG-CSF (0, 10, 50, and 100 ng mL−1, respectively). Although there were no significant effects on the various concentration of hrG-CSF treatment groups compared with control, the somatic cell NT blastocysts formation tended to increase after 10 ng mL−1 hrG-CSF treatment (24.19 ± 2.90%) compared with control (21.37 ± 2.98%). Moreover, we investigated the effects of 10 ng mL−1 hrG-CSF on in vitro culture of porcine cloned embryos derived from oocytes that were categorized into grade A (cumulus cell layer >10), grade B (10 > cumulus cell layer ≥ 3), and grade C (cumulus cell layer <3). After supplementation of 10 ng mL−1 hrG-CSF on in vitro-culture of different groups, the developmental competence, blastocyst quality, and gene transcript levels were observed. The results showed that 10 ng mL−1 hrG-CSF has no beneficial effects on cloned embryos derived from grade A oocytes (10 ng mL−1 hrG-CSF 25.35 ± 2.53% v. control 25.00 ± 2.66%), but it significantly increased blastocyst formation of embryos derived from grade B oocytes (22.09 ± 2.10%) compared with grade B control (12.09 ± 2.31%, P < 0.05). There were obvious increases in blastocyst formation derived from grade C oocytes after 10 ng mL−1 hrG-SCF treatment (25.74 ± 1.65%) compared with grade C control (16.82 ± 2.30%, P < 0.05). However, there were no significantly differences in cleavage rate and total cell number of blastocysts among each group. Otherwise, the PCNA, POU5F1, Dnmt1, Bcl2, and Bax transcript levels were significantly increased in blastocysts that were derived from grade C oocytes after 10 ng mL−1 hrG-SCF treatment compared with grade C control. In conclusion, supplementation of 10 ng mL−1 hrG-CSF in in vitro-cultured porcine embryos increased blastocyst formation of embryos derived from thin cumulus layer of oocytes by reducing apoptosis while increasing cell proliferation and nuclear reprogramming. These results provide an experimental basis for the use of poor quality oocytes for agricultural production.

Abstract
OBJECTIVE To identify the preoperative prognostic factors of upper tract urothelial carcinoma (UTUC) and construct preoperative risk stratification system. METHODS A retrospective study including 686 patients who were diagnosed with UTUC and received radical nephroureterectomy or partial ureterectomy in Peking University First Hospital during 2003 and 2013. RESULTS Of the 686 UTUC patients, 303 (44.2%) were male and 383 (55.8%) female. The postoperative pathological examination showed that 203 (29.6%) had high tumor stages (T3, T4), 300 (43.7%) had high tumor grades (G3) and 54 (7.9%) had lymph nodes metastasis (N1). After multivariate analysis, renal pelvic tumor, large tumor, estimated glomerular filtration rate (eGFR)≥30 mL/min, and male were associated with high tumor stage. Ureteral tumor, large tumor, and non-smoking history were associated with high tumor grade. Renal pelvis tumor, large tumor, and preoperative anemia were associated with positive N status. During the follow-up, 208 (30.3%) died for cancer and 210 (30.6%) developed intravesical recurrence. Multivariate analysis showed: large tumor (P=0.001), concomitant ipsilateral hydronephrosis (P=0.041), and preoperative anemia (P=0.001) were independently associated cancer-specific mortality after surgery, while ureteral tumor (P=0.04), multiple tumor (P=0.005), and high preoperative creatinine (P=0.036) were independent risk factors for intravesical recurrence. CONCLUSION Of the preoperative clinical parameters of UTUC patients, the large tumor, concomitant ipsilateral hydronephrosis, and preoperative anemia were independently associated with cancer-specific mortality after surgery. Ureteral tumor, multiple tumor, and high preoperative creatinine were independently associated with intravesical recurrence after surgery.

Abstract
Objective: To investigate the association between human papillomavirus (HPV) and lung cancer. Methods: We examined a series of 83 lung cancer patients with HPV DNA in both lung tumor specimens and adjacent normal specimens from Fujian province. Twenty-one of the most clinically relevant HPV types from the highly conserved L1 region of the viral genome were analyzed, using the PCR amplification and were followed by reverse hybridization with specific probes. Chi-square test of paired design was used to test the difference of HPV positive rates between lung cancer specimens and adjacent normal specimens. Chi-square test and Fisher's exact test were used to analyze the differences of HPV positive rate of tumor specimens on factors as gender, age, histological subtype, clinical stage, smoking status and alcohol consumption. Results: HPV was detected in 7 of the 83 tumor specimens and in 6 of the paired normal lung tissues. There was no significant correlation between HPV and lung cancer (P>0.999). Neither demographic characteristics nor clinical features were found with significant differences on HPV in lung cancer tissues (P>0.05). Conclusion: Our data showed that HPV was not significantly associated with the risk of lung cancer in Fujian province.

Abstract
We know of only limited data about the role of oral hygiene and the risk of oral cancer with different standards of education. The aim of this study was to assess the association between oral hygiene and risk of oral cancer, with stratification by standard of education, in Chinese women. We organised a case-control study with 250 women with oral cancer and 996 age-matched controls in Fujian, China. Data were collected by personal interview using a structured questionnaire. We used unconditional logistic regression with stratification by educational standard to estimate the odds ratios (OR) and 95% CI. Tooth-brushing twice a day or more was inversely related to the risk of oral cancer in women with high school education or above (OR 0.50; 95% CI 0.25 to 0.98), but not in those who were illiterate or had primary-middle school education. Wearing dentures showed an increased risk only in less well-educated women: the OR were 2.23 (95% CI 1.14 to 4.34) for the illiterate and 1.68 (95% CI 1.08 to 2.62) for the primary-middle school group. The loss of more than five teeth and oral ulceration were associated with increased risks of oral cancer in all three groups. There was also a multiplicative interaction between oral hygiene and standard of education for risk of oral cancer (p=0.001). Our results suggest that oral hygiene seems to have a critical role in the risk of oral cancer in Chinese women, but this effect may be modified by their educational standard.

Abstract
Objective: To evaluate the value of multi-parametric MRI (Mp-MRI) in the diagnosis and differential diagnosis of early prostate cancer(PCa) in the peripheral zone(PZ) and low T2WI signal intensity of prostatitis. Methods: A total of 40 patients with PZ early PCa and 37 with prostatitis of hypointense T2WI signal in PZ were retrospectively analyzed, which were collected from the General Hospital of Ningxia Medical University from Janurary 2009 to June 2015, who underwent T2WI, DWI, and DCE-MRI examination and all patients were confirmed by pathology. All the data was transferred to GE Advanced Workstation AW4.3, the indexes divided into cancerous and prostatitis regions were calculated by Functool2 of signal intensity-time(SI-T) curve and ADC value, to calcuate the time to minimum(Tmax), the whole enhancment degree (SImax). ROC cure was used to determine the cutoff value for PCa detection with the ADC value. Result: On T2WI, 57.5% of PCa (23/40) showed focal nodular homogeneous low signal intensity, 70.3% of prostatitis(26/37) showed diffuse inhomogeneous low signal intensity. DCE-MRI, the distribution of curve types for malignant tumors was type Ⅰ 2.5%(1/40), typeⅡ32.5%(13/40) and type Ⅲ 65.0% (26/40). While the numbers for prostatitis was type Ⅰ 16.2%(6/37) , type Ⅱ 56.8% (21/37) and type Ⅲ 27.0% (10/37)respectively.The patterns of curve types in malignant lesions were different from benign lesions significantly(χ2 =12.32, P<0.01). The mean values of Tmax, SImax in cancerous and prostatitis regions were (17.96±2.91)s, 1.76%±0.23% and (21.19±3.59)s, 1.53%±0.18%, respectively (t=5.37, 6.10; P<0.01). On DWI, The mean ADC values in cancerous and prostatitis regions were (0.95±0.13)×10-3 mm2/s and (1.12±0.13)×10-3 mm2/s, respectively (t=7.10, P<0.01). According to the ROC analysis, when the cutoff value was 1.01×10-3 mm2/s, the early PCa of diagnostic sensitivity, specificity and accuracy was 79.1%, 72.7% and 76.1% respectively. Conclusion: Combined with morphology and signal characteristics of conventional T2WI, DWI and DCE-MRI improve the power of MR imaging in discriminating prostatitis from early PCa.

Abstract
UNLABELLED The aim of this study was to evaluate the incremental value provided by single-photon emission computed tomography (SPECT)/spiral computed tomography (CT) over SPECT alone for the evaluation of equivocal bone lesions in patients with hepatocellular carcinoma (HCC). PATIENTS, METHODS This was a retrospective study of 65 patients (61 men and 4 women; mean age, 53.1 ± 10.1 years; age range, 31-78 years) with HCC confirmed by pathology who underwent planar whole body scintigraphy and SPECT/CT. Each lesion was scored visually using a 5-point scale (0, negative; 1, benign; 2, likely benign; 3, likely bone metastasis; 4, bone metastasis). Lesions in which diagnostic confidence was scored as 3 or 4 were categorized into metastases.The final diagnosis of each lesion was based on pathological confirmation or follow-up by whole body scintigraphy and SPECT/spiral CT conducted two or more times. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of SPECT alone and SPECT/CT were computed. RESULTS The diagnostic accuracy, sensitivity, specificity, PPV, and NPV of SPECT alone were 78.4, 70.9%, 94.9%, 96.8% and 59.7%, respectively. Moreover, for agreement of SPECT alone and the final results, the kappa value was 0.567 (p < 0.001), which was considered to be moderate agreement. The diagnostic accuracy, sensitivity, specificity, PPV, and NPV of SPECT/CT were 99.2%, 100%, 97.4%, 98.9% and 100 %, respectively. Furthermore, for agreement of SPECT/CT and the final results, the kappa value was 0.981 (p < 0.001), which was considered to be nearly perfect agreement. CONCLUSIONS SPECT/spiral CT is more accurate and valuable than SPECT alone in the differential diagnosis of equivocal bone lesions in patients with HCC.

Abstract
A pilot scale co-rotating, self-wiping twin-screw extruder was used to produce high-moisture texturised meat analogue products from defatted soy protein and lean pork blend with different combinations of operational variables and feed compositions. The effects of operational variables and feed compositions that include temperature setting in five heating zones of the extruder, screw speed, throughput, moisture content, oil content, and pork percentage upon sensory textual quality were determined. The optimal sensory texture and energy consumption of extrusion cooking of the feed blend were obtained with a die of rectangular slit configuration, barrel temperature setting at 60-100-120-150-110°C, screw speed at 80rpm, 50% moisture content, lean pork content ranging from 30-50%, and the oil content ranging from 12-16% (depending upon the fat content of the pork) for optimal extrudate texture formation and stable operation.

Abstract
OBJECTIVE To investigate the clinical characteristics, treatment and prognosis of primary penoscrotal extra-mammary Paget's disease (PSPD). METHODS The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed. Survival rate of the overall patients, the invasive patients, and the patients with positive surgical margin or negative surgical margin were analyzed with Kaplan-Meier survival curve method. RESULTS Among all the patients with primary PSPD, the median age of onset was 64.5 (39-84) years, the median time of disease duration was 40 (2-300) months, and the median long diameter of lesion was 4.75 (1-10) cm. In the study, 12 patients (54.5%) were in pathological stage A1, 6 patients (27.3%) were in pathological stage A2, and 4 patients (18.2%) were in pathological stage B. Scrotum and penile of most patients (n=12, 54.5%) were involved, 5 patients (22.7%) were scrotum only, and 5 patients (22.7%) were penile only. Erythema (n=18, 81.8%), itchiness (n=16, 72.7%), ulcerate (n=12, 54.5%), exudation (n=11, 50.0%), and pain (n=4, 18.2%) were the major manifestations. All the patients with primary PSPD were treated with wide surgical excision. The rate of invasive patients was 77.3% (n=17). Of them, 6 patients had positive surgical margin. The surgical margins of non-invasive patients were all negative. Twelve patients exhibited local recurrence or/and metastases, and the status of surgical margins (P=0.015) and the depth of invasion (P=0.010) were important risk factors. Inguinal lymph nodes were generally involved. The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P=0.040). The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively. The patients with positive surgical margin had poor prognosis. CONCLUSION Primary PSPD, with the characteristics of long duration, high invasive tendency and high incidence of local recurrence or metastases, generally occurs in the elderly. Surgery should be performed at first. The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors. Biopsy, frozen section and inguinal lymph node biopsy (ILNB) can standardize diagnosis and treatment.

Abstract
Background This phase 3 trial is the first to evaluate the efficacy and safety of treatment with the systemic TNF‐α inhibitor, adalimumab, for Chinese patients with moderate‐to‐severe plaque psoriasis. Methods In the 12‐week, double‐blind, placebo‐controlled Period A, patients were randomized 4 : 1 to receive adalimumab 40 mg every‐other‐week (following a single 80 mg dose), or placebo every‐other‐week. In the subsequent 12‐week, open‐label, Period B, all patients received adalimumab 40 mg every‐other‐week starting at week 13, following a single, blinded dose at week 12 of adalimumab 80 mg or matching placebo (for patients receiving placebo or adalimumab in Period A respectively). In Period A, efficacy was analysed for all randomized patients and safety for all patients receiving ≥1 dose of the study drug. Results For the 425 patients in this study (87 placebo; 338 adalimumab), a higher percentage randomized to adalimumab achieved the primary endpoint of ≥75% improvement from baseline in PASI score (PASI 75) at week 12: placebo 11.5% (10/87); adalimumab 77.8% (263/338; P < 0.001). Physician's Global Assessment of clear to minimal was achieved at week 12 by 14.9% placebo (13/87) and 80.5% adalimumab (272/338; P < 0.001). For patients who received adalimumab at any time during the study (All‐adalimumab Population), treatment‐emergent adverse events (AEs) were reported by 63.4%; the most common was upper respiratory infection (16.1%). Serious AEs were reported by 3.5% of the All‐adalimumab Population, and serious infectious AEs by 1.2%, which include lung infection, pneumonia and tuberculosis [2 (0.5%) patients each]. There was one death (chronic heart failure). Conclusion In these Chinese patients with moderate‐to‐severe psoriasis, a significantly greater percentage treated with adalimumab compared with placebo achieved efficacy endpoints at week 12 and efficacy was sustained to week 24. Safety results were consistent with the known adalimumab safety profile; no new safety signals were identified in the 24 weeks of treatment.
