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.

Abstract
Objective: To investigate the clinical manifestation, diagnosis, treatment and outcome of simultaneous occurrence of renal cell carcinoma and urothelial carcinoma. 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.
