Abstract
This study investigates the expression of interleukin (IL)-17 (IL-17A and IL-17D) and its role in ovarian epithelial tumor and its correlation with the clinical characteristics. Fifty malignant ovarian epithelial tumor specimens were collected after surgery and set as group A. Ten benign epithelioma specimens and ten normal epithelial specimens were set as group B and C, respectively. The expression of IL-17A and IL-17D in the three groups was detected using the EnVision method, and the correlation of positive expression rate with pathological type, clinical stage, presence of ascites and differentiation degree was analyzed. Group A had higher expression of IL-17A and IL-17D compared to group B and C (p less than 0.05). The expression rate was in correlation to clinical stage and differentiation degree, but in no correlation to pathological type and presence of ascites. The expression rate of malignant epithelioma in the early stage was lower than that in the late stage (p less than 0.05). Lower differentiation degree indicated higher expression rate (p less than 0.05). Pathological type and presence of ascites had no remarkable influence on the expression rate (p>0.05). Study of the expression of IL-17 provides theoretical support for the clinical treatment and prognosis prediction of ovarian epithelial tumor.

Abstract
Based on the one-dimensional tight-binding Su-Schrieffer-Heeger (SSH) model, and using the molecular dynamics method, we discuss the dynamics of electron and hole polarons propagating along a polymer chain, as a function of the distance between side radicals and the magnitude of the transfer integrals between the main chain and the side radicals. We first discuss the average velocities of electron and hole polarons as a function of the distance between side radicals. It is found that the average velocities of the electron polarons remain almost unchanged, while the average velocities of hole polarons decrease significantly when the radical distance is comparable to the polaron width. Second, we have found that the average velocities of electron polarons decrease with increasing transfer integral, but the average velocities of hole polarons increase. These results may provide a theoretical basis for understanding carriers transport properties in polymers chain with side radicals.

Abstract
OBJECTIVE To study the perioperative management and surgical treatment of patients with neurosurgical critical diseases and thrombocytopenia. METHODS Eleven patients with the diagnosis of neurosurgical critical diseases and thrombocytopenia who received surgical treatment in Department of Neurosurgery, Peking Union Medical College Hospital from 2010 to 2015 were reviewed retrospectively. All eleven patients received platelet transfusions preoperatively. The safety and efficacy of surgical treatment were analyzed by GOS score at 6 months after operations. RESULTS Platelet counts of six patients who received minimally invasive surgery reached 80×10(9) /L by platelet transfusions preoperatively. Platelet counts of five patients who received Craniotomy and ventriculoperitoneal shunt reached 100×10(9) /L by platelet transfusions preoperatively. Eight patients received platelet transfusions postoperatively according to a low platelet count 24 hours after operations. Two patients died after surgery and one died after discharge. All other eight survival patients got well recovery with an average GOS score of 4.5 at six months after operations. CONCLUSIONS Patients with neurosurgical critical diseases and thrombocytopenia could receive surgical treatment in collaboration with relative departments.

Abstract
The β-decay half-lives of 94 neutron-rich nuclei ^{144-151}Cs, ^{146-154}Ba, ^{148-156}La, ^{150-158}Ce, ^{153-160}Pr, ^{156-162}Nd, ^{159-163}Pm, ^{160-166}Sm, ^{161-168}Eu, ^{165-170}Gd, ^{166-172}Tb, ^{169-173}Dy, ^{172-175}Ho, and two isomeric states ^{174m}Er, ^{172m}Dy were measured at the Radioactive Isotope Beam Factory, providing a new experimental basis to test theoretical models. Strikingly large drops of β-decay half-lives are observed at neutron-number N=97 for _{58}Ce, _{59}Pr, _{60}Nd, and _{62}Sm, and N=105 for _{63}Eu, _{64}Gd, _{65}Tb, and _{66}Dy. Features in the data mirror the interplay between pairing effects and microscopic structure. r-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system.

Abstract
OBJECTIVE To analyze whether there are differences in the efficacy and clinical outcomes to first-line tyrosine kinase inhibitors (TKI) therapy in Chinese patients with metastatic non-small-cell lung cancer (NSCLC) harboring different subtypes of epidermal growth factor receptor (EGFR) mutations. METHODS A retrospective analysis was made on the clinical data of stage ⅢB or Ⅳ NSCLC patients who were diagnosed by histology and received EGFR mutation test, in order to confirm if there is any difference between the therapeutic effects of TKIs as first-line therapy and the prognosis. RESULTS A total of 165 patients harboring EGFR exon 19 deletion (19del, n=71), exon 21 L858R mutation (L858R, n=80) or uncommon sensitive mutation (n=14) were treated with EGFR-TKIs for first-line treatment. The comparison among different groups of common types of sensitive mutations revealed that the objective response rate (ORR) of group 19del and group L858R were 57.8% and 45.0%, respectively (P=0.113). The disease control rate (DCR) was 93.0% and 93.8%, respectively (P=0.158). However, the ORR and DCR of uncommon sensitive mutation were 35.7% and 78.6%, which were significantly lower than that of the group 19del (P=0.035) and group L858R (P=0.020). The median progression-free survival (PFS) of group 19del, group L858R and uncommon sensitive mutation were 14.0 months, 7.8 months and 5.1 months, respectively (P=0.001). The median PFS of the group 19del was significantly longer than that of the group L858R (P=0.009). The median overall survival (OS) of these three groups had significant difference (22.8, 15.2 and 10.0 months) (P=0.048). But those of group 19del and group L858R were similar (P=0.152). The multivariate analysis indicated that ECOG-PS (P=0.030), cigarette smoking (P=0.013) and EGFR mutation types (P=0.034) are independent prognostic factors of OS. CONCLUSIONS For Chinese NSCLC patients with different types of sensitive mutation, there are differences between their efficacy and prognosis of EGFR-TKIs as first-line treatment. The PFS of group 19del is obviously longer than that of other types of sensitive mutations, but have no significant differences in OS. The PFS and OS of patients with common types of sensitive mutation are better than those with uncommon sensitive mutation.

Abstract
The incidence of non-Hodgkin lymphoma (NHL) in China is increasing and is attracting attention as a topic of research. The percentage of NHL cases in ethnic Uighur people is also gradually increasing. We therefore recruited Uighur people with NHL to investigate the correlation between genetic alternations and clinical/pathological features in an attempt to determine their clinical significance. A total of 60 NHL patients were recruited from our hospital for a microscopic examination of their tumor cell morphology. Further analysis of chromosome karyotypes revealed the relationship between genetic alternations and clinical/pathological features. Microscopic examination revealed increased numbers of tumor cells with altered morphology. The recruited patients all exhibited abnormal karyotypes. Chromosomal breakages were detected at 14q32, 18q21, 6q21-25, +3, +, +18, and short tandem repeat 17 (str17) in 18.3, 25, 25, 18.3, 15, and 21.7% of patients, respectively. Karyotype change was not related to age, gender, performance status score, or pathological type (P > 0.05), but was correlated with clinical stage, average lactate dehydrogenase (LDH) level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy (P < 0.05). Independent risk factors for genetic change in Uighur NHL patients included clinical stage, average LDH level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy (P < 0.05). Uighur NHL patients exhibited genetic changes including t(14:18), 6q21-25, +3, +7, +18, and str17. Clinical stage, average LDH level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy were all independent risk factors for NHL.

Abstract
This study was conducted to determine the effect of immunization with inhibin DNA vaccine delivered by attenuated Salmonella choleraesuis on ovarian responses and fertility in cross-bred buffaloes. A total of 134 cross-bred buffaloes were divided into four groups: groups T1 (n = 34), T2 (n = 35) and T3 (n = 31) were nasal immunized twice a day with 10 ml of 1 × 1010 CFU/ml of the C501 (pVAX-asd-IS) vaccine for 5, 3 and 1 day, respectively. Group C (n = 34) was nasal immunized with 10 ml PBS for 5 days. All animals were immunized twice with an interval of 14 days and administered with 200 μg of a GnRH analogue on day 28, 0.5 mg PGF2α on day 35 and 200 μg of the same GnRH analogue on day 37. TAI was performed at 18 and 24 hr after the second GnRH treatment. Fourteen days after primary immunization, C501 (pVAX-asd-IS) elicited significant immune responses, and anti-inhibin IgG antibody titres in group T1 were significantly higher (p < .01) than groups T3 and C. After the second GnRH treatment, the growth speed of the dominant follicles in group T1 was significantly faster (p < .05) than groups T3 and C. The number and diameter of large follicles (≥10 mm) as well as ovulatory follicles in group T1 were the greatest in all groups, resulting in a greater conception rate in buffaloes with positive anti-inhibin antibodies. These results demonstrate that immunization with the C501 (pVAX-asd-IS) vaccine, coupled with the Ovsynch protocol, could be used as an alternative approach to improve reproductive performance in cross-bred buffaloes.

Abstract
The production of voice is related to the coordinated operation of respiratory system,phonation system and resonance system.Sonic wave which is produced by the vibration of vocal fold goes through the resonating cavities to bring the voice out.Hearing and voice are two kinds of functions which are very related.Hearing impaired children have a very strong tendency to be in communication with people by improving the volume of their voice(Lombard's effect).To summarize the reasons,the methods of assessment and therapy of voice problems of hearing impaired children.Review 32 literature related to voice problems of hearing impaired children in the near past 12 years.Hearing intervention and improper way of phonation have great effect on the voice health of hearing impaired children.There are few studies on the therapy efficiency and auditory feedback training of voice problems of hearing impaired children,which are expecting our further study.

Abstract
Although various individual studies have evaluated the correlation between monoamine oxidase B (MAOB), polymorphism, and Parkinson's disease (PD), the results remain inconclusive. Therefore, we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between the MAOB polymorphism and PD. Eligible studies were identified via databases such as PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine, throughout November 2015. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strengths of these associations. Eight studies documenting a total of 1385 cases of PD and 1426 controls were included in this meta-analysis. Overall, no significant association was found between the MAOB A644G polymorphism and PD risk in the Chinese population. However, in subgroup analyses, where results were stratified by geographical areas and source of controls, increased risk for PD in Northern China was observed (allele A vs G: OR = 1.33, 95%CI = 1.11-1.58; AA vs GG: OR = 1.46, 95%CI = 1.09-1.97; AA + AG vs GG: OR = 1.42, 95%CI = 1.06-1.90). Similarly, population-based studies also showed significant association between the MAOB A644G polymorphism and PD risk among different populations (allele A vs G: OR = 1.29, 95%CI = 1.11-1.51; AA vs GG: OR = 1.41, 95%CI = 1.09-1.82; AA + AG vs GG: OR = 1.34, 95%CI = 1.04- 1.71). In conclusion, this meta-analysis provided evidence that the MAOB A644G polymorphism may contribute to PD development in Northern China. Further studies conducted in other ethnic groups are required for definite conclusions.

Abstract
Sinopodophyllum hexandrum is an important medicinal plant that has been listed as an endangered species, making the conservation of its genetic diversity a priority. Therefore, the genetic diversity and population structure of S. hexandrum was investigated through inter-simple sequence repeat analysis of eight natural populations. Eleven selected primers generated 141 discernible fragments. The percentage of polymorphic bands was 37.59% at the species level, and 7.66-24.32% at the population level. Genetic diversity of S. hexandrum was low within populations (average HE = 0.0366), but higher at the species level (HE = 0.0963). Clear structure and high genetic differentiation were detected between populations using unweighted pair groups mean arithmetic and principle coordinate analysis. Clustering approaches clustered the eight sampled populations into three major groups, and AMOVA confirmed there to be significant variation between populations (63.27%). Genetic differentiation may have arisen through limited gene flow (Nm = 0.3317) in this species. Isolation by distance among populations was determined by comparing genetic distance versus geographical distance using the Mantel test. The results revealed no correlation between spatial pattern and geographic location. Given the low within-population genetic diversity, high differentiation among populations, and the increasing anthropogenic pressure on this species, in situ conservation measures, in addition to sampling and ex situ preservation, are recommended to preserve S. hexandrum populations and to retain their genetic diversity.

Abstract
AIM To study prospectively the ethnic-specific risks of cardiovascular disease, end-stage renal disease and all-cause mortality in patients with Type 2 diabetes mellitus among native Asian subpopulations. METHODS A total of 2337 subjects with Type 2 diabetes (70% Chinese, 17% Malay and 13% Asian Indian) were followed for a median of 4.0 years. Time-to-event analysis was used to study the association of ethnicity with adverse outcomes. RESULTS Age- and gender-adjusted hazard ratios for cardiovascular disease in ethnic Malay and Asian Indian subjects were 2.01 (1.40-2.88; P<0.0001) and 1.60 (1.07-2.41; P=0.022) as compared with Chinese subjects. Adjustment for conventional cardiovascular disease risk factors, including HbA1c , blood pressure and lipid profile, slightly attenuated the hazards in Malay (1.82, 1.23-2.71; P=0.003) and Asian Indian subjects (1.47, 0.95-2.30; P=0.086); However, further adjustment for baseline renal function (estimated GFR) and albuminuria weakened the cardiovascular disease risks in Malay (1.48, 0.98-2.26; P=0.065) but strengthened that in Asian Indian subjects (1.81, 1.14-2.87; P=0.012). Competing-risk regression showed that the age- and gender-adjusted sub-distribution hazard ratio for end-stage renal disease was 1.87 (1.27-2.73; P=0.001) in Malay and 0.39 (0.18-0.83; P=0.015) in Asian Indian subjects. Notably, the difference in end-stage renal disease risk among the three ethnic groups was abolished after further adjustment for baseline estimated GFR and albuminuria. There was no significant difference in risk of all-cause mortality among the three ethnic groups. CONCLUSIONS Risks of cardiovascular and end-stage renal diseases in native Asian subjects with Type 2 diabetes vary substantially among different ethnic groups. Differences in prevalence of diabetic kidney disease may partially explain the ethnic disparities.

Abstract
AIM Recent findings highlight the critical role of the Wnt signaling pathway in cardiac repair and stem cell regulation. Our previous study shows that lithium chloride (LiCl) optimizes skeletal myoblast (SkM) for transplantation by mimicking the Wnt/β-catenin signaling activities. In this study, we evaluate the therapeutic potential of SkMs genetically modified with Wnt1gene (Wnt1 SkMs) in a rat model with myocardial infarction (MI). METHODS We harvested neonatal SkMs using Wistar rats (1-3-day old) transfected with p-EGFP-C3-Wnt1 plasmid. RT-PCR and immunofluorescence showed a higher expression of Wnt1 in the Wnt1 SkMs. We observed that Wnt1 SkMs increased connexin 43 (Cx43) expression, reduced apoptosis induced by hydrogen peroxide (H2O2) and decreased caspase-3 expression via the canonical Wnt signaling pathways compared to the empty vector transfected SkMs (control SkMs). For in vivo studies, the myocardial infarction model was developed in the Wistar rats. The rats were grouped to receive 100 μL basal DMEM without cells or containing 1.5×106SkMs and Wnt1 SkMs. Histological studies revealed improved survival of SkMs, reduced cardiomyocytes apoptosis, and upregulated expression of Cx43 in Wnt1 SkMs therapy group. Echocardiography monitored four weeks after therapy showed improvement of the left ventricular function in rats treated with Wnt1SkMs compared to other groups. CONCLUSION Transplantation of Wnt1 SkMs improves rat myocardial function and enhances anti apoptotic properties of both SkMs and cardiomyocytes and upregulation of tissue Cx43 after infarction via the canonical Wnt/β-catenin signaling activities.

Abstract
The aim of this study was to study the relationship of EGFR DNA methylation with the severity of non-small-cell lung cancer (NSCLC). We enrolled 54 patients with NSCLC between March 2013 and June 2014 from Department of Cardiothoracic Surgery in our hospital. The methylation levels in the promoter region of the EGFR gene in cancerous and pericarcinomatous tissue were tested by pyrosequencing. EGFR mRNA expression levels were detected by real-time reverse-transcription polymerase chain reaction. The SPSS software was used for data analysis. We found that EGFR gene methylation levels showed no significant differences among patients of different gender, age, or smoking status. EGFR DNA methylation levels significantly increased (P < 0.05) following NSCLC malignancy upgrading, and showed negative correlation with mRNA expression (P = 0.041). DNA methylation levels of cancerous tissues were significantly higher compared to the corresponding pericarcinomatous tissues (P < 0.05) at stages I, II, and IIIA. The methylation levels at loci 3, 6, 9 among the detected CpG islands were higher in the cancer tissues at each stage (P < 0.05). In summary, our results suggest that the DNA methylation levels of EGFR can be used as an important indicator for the stage of cancer tissue malignancy.

Abstract
Osteosarcoma represents an aggressive type of bone malignancy that poses a significant health threat. The objective of the current study was to analyze the effect and mechanism of dihydroartemisinin (DHA) on the proliferation, metastasis and apoptosis of human osteosarcoma cells. A gradient concentration of DHA (15, 25 and 35 μmol.L-1) was used to stimulate the cells, along with control and Dimethyl sulfoxide (DMSO). The phenotypic outcomes were characterized using MTT assay, clone formation assay, Hoechst 33258 staining assay, luciferase reporter plasmid assay, Western blot and wound healing assay. In addition, IBM SPSS Statistics 18.0 software was applied for statistical analysis and all experimental data were expressed as mean ± s.d. Analysis of variance (ANOVA) was applied to compare the differences among multiple groups. Our results demonstrated that DHA inhibited the proliferation and metastasis of osteosarcoma cells and promoted the apoptosis in the cytomorphosis.

Abstract
The aim of this study was to explore epidermal growth factor receptor (EGFR) gene amplification and its relationship with cancer invasion and metastasis in non-small cell lung cancer (NSCLC). EGFR amplification in 45 patients with NSCLC and 15 subjects with normal lung tissues was detected by fluorescence in situ hybridization. The relationship between EGFR amplification and the clinicopathologic features of NSCLC was analyzed. EGFR gene amplifications were identified in 2 of 15 normal lung tissues (13.33%) and in 29 of 45 NSCLCs (64.44%). Patients <60 years had a 66.67% EGFR amplification rate, while patients ≥60 years had a rate of 62.50%. The EGFR amplification rates in male and female patients were 64.0% (16/25) and 65.0% (13/20), respectively. Pathologically, the EGFR amplification rate of patients with squamous cell carcinoma was 56.52% (13/23), and with adenocarcinoma was 72.72% (16/22). The EGFR amplification rate in NSCLCs with well-moderate differentiation was lower than in those with poor differentiation; 48.0% (12/25) vs 85.0% (17/20), respectively. Patients with lymph node metastasis had nearly double the amplification rate than those without metastasis; 90.0% (18/20) vs 44.0% (11/25), respectively. The rate of EGFR amplification was significantly higher in NSCLC than in normal lung tissue (64.44 vs 13.33%, P < 0.05), and was not correlated with age or gender (P > 0.05), but increased with clinical stage in NSCLCs (P < 0.05). Overall, these studies found that the rate of EGFR gene amplification was increased significantly in NSCLC and was closely related to lymphatic metastasis and TNM stage.

Abstract
BACKGROUND Body mass index (BMI), a measure of obesity typically assessed in middle age or later, is known to be positively associated with pancreatic cancer. However, little evidence exists regarding the influence of central adiposity, a high BMI during early adulthood, and weight gain after early adulthood on pancreatic cancer risk. DESIGN We conducted a pooled analysis of individual-level data from 20 prospective cohort studies in the National Cancer Institute BMI and Mortality Cohort Consortium to examine the association of pancreatic cancer mortality with measures of central adiposity (e.g. waist circumference; n = 647 478; 1947 pancreatic cancer deaths), BMI during early adulthood (ages 18-21 years) and BMI change between early adulthood and cohort enrollment, mostly in middle age or later (n = 1 096 492; 3223 pancreatic cancer deaths). Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression models. RESULTS Higher waist-to-hip ratio (HR = 1.09, 95% CI 1.02-1.17 per 0.1 increment) and waist circumference (HR = 1.07, 95% CI 1.00-1.14 per 10 cm) were associated with increased risk of pancreatic cancer mortality, even when adjusted for BMI at baseline. BMI during early adulthood was associated with increased pancreatic cancer mortality (HR = 1.18, 95% CI 1.11-1.25 per 5 kg/m(2)), with increased risk observed in both overweight and obese individuals (compared with BMI of 21.0 to <23 kg/m(2), HR = 1.36, 95% CI 1.20-1.55 for BMI 25.0 < 27.5 kg/m(2), HR = 1.48, 95% CI 1.20-1.84 for BMI 27.5 to <30 kg/m(2), HR = 1.43, 95% CI 1.11-1.85 for BMI ≥30 kg/m(2)). BMI gain after early adulthood, adjusted for early adult BMI, was less strongly associated with pancreatic cancer mortality (HR = 1.05, 95% CI 1.01-1.10 per 5 kg/m(2)). CONCLUSIONS Our results support an association between pancreatic cancer mortality and central obesity, independent of BMI, and also suggest that being overweight or obese during early adulthood may be important in influencing pancreatic cancer mortality risk later in life.

Abstract
To observe the radiotherapy sensitization effect of retroperitoneal lymph node metastasis in patients by sodium glycididazole in recent clinical efficacy and toxicity. A total of 42 patients admitted with metastasis and recurrence of retroperitoneal lymph node from September 2006 to December 2009 were classified with the method of case-control. After three dimensional conformal radiation therapy with or without sodium glycididazole (800 mg/m²) for sensitization, the results of recent clinical efficacy, relief of pain, and Karnofsky score were obtained. Tumor remission rate of patients in sensitization group (with sodium glycididazole) at post-radiotherapy 3 months was significant higher than that in control group (without sodium glycididazole) (52% vs. 24%; P<0.05). Oral dose of morphine daily, and Karnofsky score in anterior-posterior radiotherapy of patients in the sensitization group were significant different with those in the control group (93 ± 12 and 42 ± 6 mg vs. 94 ± 12 and 20 ± 5 mg and (65 ± 4) and (90 ± 9) vs. (64 ± 5) and (80 ± 10), respectively; P<0.01). Sodium glycididazole has positive radiotherapy sensitization to the metastasis or recurrence of retroperitoneal lymph node for digestive tract cancer, which could obviously improve the life quality or release the pain for patients.

Abstract
Spermatogenesis, is a complex process of precisely regulated intracellular events, where it is affected by many factors. Long-distance transport of animals is one of the stressors that may influence spermatogenesis and sperm quality. The present study chose luteinizing hormone receptor (LHR), androgen receptor (AR), and heat-shock protein 70 (HSP70) as our target genes to investigate their mRNA and protein expression in the testes of long-distance transported (about 1000 km) mice. Histological analysis showed that there was a reduction in the thickness of the seminiferous epithelium in the transported mice, and a significant decrease in body weight and sperm count in the epididymis was also observed. mRNA expression was determined by QPCR in the testis of transported and control mice. The levels for AR decreased significantly in transported mice. LHR and HSP70 expression in the testes of the transported mice was slightly higher than that of control mice but did not reach a significant level. A similar tendency of protein expression was also observed by Western blot analysis. The levels of LHR and HSP70 increased slightly after transportation. However, none of the changes were statistically significant compared with the control mice. In conclusion, long-distance transport has an adverse effect on reproductive organs and spermatozoa in adult mice.

Abstract
Cantharidin is a biomolecule with a role in host defense that can also be used as an anticancer drug. The in vivo biosynthetic pathway for cantharidin has been the subject of debate for several decades and the mechanism is not yet completely understood. To study the biosynthetic pathway of cantharidin in blister beetles, Mylabris cichori, a full-length MenA (McMenA) cDNA was cloned based on the partial sequence of the MenA gene from a suppression subtractive hybridization (SSH) library of male and female adult M. cichorii. The cDNA was 1264 base pairs (bp) with an open reading frame of 1026 bp nucleotides encoding a 341 amino acid protein. Analysis of the McMenA amino acid sequence showed that the aspartate rich motif N/DDxxD represented binding sites for prenyl diphosphate via a Mg(2+) ion. Phylogenetic analysis showed that McMenA was most closely related to MenA of Tribolium castaneum, and the amino acid sequence similarity was 86%. The expression pattern of McMenA in adults was analyzed using RT-qPCR, and we found that the highest expression of McMenA occurred during 22-25 days in the sex-separate breeding males, while the lowest expression occurred in females at the same time. Injection with a specific double-strand RNA (dsRNA) of McMenA led to a significant reduction of McMenA mRNA levels after 24 h. Cantharidin and ATP concentrations dropped around the same time. Together, our data showed that the McMenA gene might be involved in cantharidin biosynthesis.

Abstract
PURPOSE The aim of this study was to identify the correlations of IFN-γ-inducible protein-10 (IP-10) with the risk of chronic hepatitis B (CHB) and the efficacy of interferon therapy in Asians. METHOD Serum IP-10 levels were assayed using enzyme linked immunosorbent assay (ELISA) in both CHB and control group. CHB group received interferon-α2b treatment to compare the pre-treatment and post-treatment serum IP-10 levels. Relevant studies met predefined inclusion and exclusion criteria were enrolled into further meta-analysis. Stata 12.0 software was applied for data analysis. RESULT Our case-control study demonstrated that CHB group had evaluated serum IP-10 levels compared with control group (285.7 ± 41.6 pg/mL vs. 79.1 ± 33.8 pg/mL, t = 21.85, P < 0.001. After treatment for 12 weeks, CHB group had remarkably decreased post-treatment serum IP-10 levels than pre-treatment (78.5 ± 20.4 pg/mL vs. 285.7 ± 41.6 pg/mL, t = 33.76, P < 0.001). No significance was observed on post-treatment serum IP-10 levels between CHB and control group (78.5 ± 20.4 pg/mL vs. 78.1 ± 33.8 pg/mL, t = 0.07, P = 0.947). Meta-analysis results demonstrated that serum IP-10 levels in CHB group were obviously higher than healthy controls (SMD = 2.21, 95% CI = 1.55~2.87, P < 0.001). A subgroup based on the HBeAg states revealed that serum IP-10 levels in both HBeAg-positive and HBeAg-negative CHB patients were notably higher than healthy controls (HBeAg-positive: SMD = 2.00, 95% CI = 1.13-2.87, P < 0.001; HBeAg-negative: SMD = 1.34, 95% CI = 0.97-1.72, P < 0.001). CONCLUSION Serum IP-10 may be correlated with the risk of CHB and the efficiency of interferon therapy, thus IP-10 may be a good biomarker for the diagnosis and treatment of CHB.

Abstract
The population of Magnolia sprengeri individuals deceased drastically in the late 20th century because of the widespread harvest for traditional Chinese medicinal recipes. In this study, the levels of phenotypic variation and the genetic structure of 2 populations of M. sprengeri were estimated. The phenotypic variation of M. sprengeri characteristics was nonsynchronous, with a coefficient of variation for 37 characters from 9.55-35.87%. The variance stabilizing transformation value ranged from 0.034-52.344%. The variation contribution within the population was greater than the contribution among the population; the among-population rate was 2.864%, while the within-population rate was 15.849%; values of repeatability for among-population and within-population were 0.430 and 0.098, respectively. This indicates that more variation arose from within-population and that population repeatability was much greater than individual repeatability. Variation in the flower organ was greater than that in the leaf organ; this means that vegetative variation was more stable than reproductive variation. Variation in the southern population was greater than that in the northern population.

Abstract
The tryptophan/kynurenine pathway (TKP) is the main route of tryptophan degradation and generates several neuroactive and immunomodulatory metabolites. Experimental and clinical data have clearly established that besides fat, muscle and liver, pancreatic islet tissue itself is a site of inflammation during obesity and type 2 diabetes. Therefore it is conceivable that pancreatic islet exposure to increased levels of cytokines may induce upregulation of islet kynurenine metabolism in a way resembling that seen in the brain in many neurodegenerative disorders. Using normal rat islets and the INS-1 β-cell line, we have demonstrated for the first time that: 1/only some TKP genes are constitutively expressed, both in β-cells as well as non β-cells; 2/ the regulatory enzyme indoleamine 2,3-dioxygenase (IDO1) is not constitutively expressed; 3/ IDO1 and kynurenine 3-monoxygenase (KMO) expression are potently activated by proinflammatory cytokines (IFN-γ, IL-1β) and glucolipotoxicity respectively, rather in β-cells than in non β-cells; 4/ Islet kynurenine/kynurenic acid production ratio is enhanced following IFN-γ and glucolipotoxicity; 5/ acute exposure to KYN potentiates glucose-induced insulin secretion by normal islets; and 6/ oxidative stress or glucocorticoid modulates TKP genes only marginally. Pancreatic islets may represent a new target tissue for inflammation and glucolipotoxicity to activate the TKP. Since inflammation is now recognized as a crucial mechanism in the development of the metabolic syndrome and more specifically at the islet level, it is needed to evaluate the potential induction of the TKP in the endocrine pancreas during obesity and/or diabetes and its relationship to the islet cell functional alterations.

Abstract
OBJECTIVE Ovarian cancer is the sixth most common cancer and the main cause of death in women. However, the molecular mechanism for the cause of the ovarian cancer has not been fully elucidated. Acid sphingomyelinase (ASM), a lipid hydrolase, has been suggested for treating cancer and may affect the development of ovarian cancer. We want to find the function of ASM in the development of ovarian cancer. PATIENTS AND METHODS Human ovarian cancer cells HO 8910 (HOCC) and human primary ovarian cells (HPOC) were transfected with ASM gene and ASM RNAi. Real-time qPCR and western blot analysis was carried out to examine the level of ASM. The growth rate of transfected and non-transfected cells was measured. Ovarian biopsies were collected from 80 ovarian cancer patients and 20 healthy subjects. RESULTS The growth rate of HOCC and HPOC was decreased by 22% and 19% in the ASM-transfected group compared with non-transfected group. Inversely, the growth rate of HOCC and HPOC was increased by 16% and 35% in the ASM-RNAi-transfected group compared with non-transfected group. In the transfected and non-transfected cells, the change level of SAM was approved by Real-time qPCR and western blot analysis. The levels of SAM were reducing with the development of ovarian cancer. CONCLUSIONS SAM is higher expressed in normal cell than that in ovarian cancer, and can be a negative biomarker for the diagnosis of ovarian cancer. SAM can be developed a new drug for the ovarian cancer therapy.

Abstract
T cell functional exhaustion during chronic hepatitis B virus (HBV) infection may contribute to the failed viral clearance; however, the underlying molecular mechanisms remain largely unknown. Here we demonstrate that jumonji domain-containing protein 6 (JMJD6) is a potential regulator of T cell proliferation during chronic HBV infection. The expression of JMJD6 was reduced in T lymphocytes in chronic hepatitis B (CHB) patients, and this reduction in JMJD6 expression was associated with impaired T cell proliferation. Moreover, silencing JMJD6 expression in primary human T cells impaired T cell proliferation. We found that JMJD6 promotes T cell proliferation by suppressing the mRNA expression of CDKN3. Furthermore, we have identified platelet derived growth factor-BB (PDGF-BB) as a regulator of JMJD6 expression. PDGF-BB downregulates JMJD6 expression and inhibits the proliferation of human primary T cells. Importantly, the expression levels of JMJD6 and PDGF-BB in lymphocytes from CHB patients were correlated with the degree of liver damage and the outcome of chronic HBV infection treatment. Our results demonstrate that PDGF-BB and JMJD6 regulate T cell function during chronic HBV infection and may provide insights for the treatment strategies for CHB patients.

Abstract
The cause of postoperative failure after the treatment of femoral intertrochanteric fracture with proximal femoral nail antirotation (PFNA) was analyzed, and the reoperative methods were examined. Nine failures of 308 femoral intertrochanteric fracture patients with PFNA were treated with femoral prosthesis total hip replacement (THR) and reoperative internal fixation. All nine patients were analyzed to determine the cause of failure. The causes of failed internal fixation in the intertrochanteric-fractured patients included perforation of the helical blade into the hip joint in three cases, cutting-out of the helical blade exit outside in two cases, and hip varus as a result of cutting-out the helical blade in two cases. Seven patients with failed internal fixation were treated with THR. Two patients who had femoral shaft fractures at the end of the nail were treated with longer PFNA. Faulty operative procedures, unsatisfactory reductions, serious osteoporosis, and incorrect positioning of the helical blade were the most important factors responsible for the failed internal fixation. Satisfactory results were achieved with THR and refixation relative to the causes of the failed internal fixation.

Abstract
Autogenous arteriovenous fistula (AVF) is the first choice for hemodialysis access in renal failure with uremia. However, AVF cannot be performed in some patients due to small and narrow veins in the forearm. In this study, a Fogarty catheter was used to establish autogenous radiocephalic hemodialysis access in patients with small caliber cephalic veins, and the patency rate and complications of this method were observed. Sixty-seven patients with uremia were divided into a treatment group (40 cases, caliber of cephalic veins<2.5 mm) and a control group (27 cases, caliber of cephalic veins≥2.5 mm). According to ultrasound results, the treatment group received AVF after expansion with a Fogarty catheter, and the control group received traditional AVF. The fistula patency rate and complications were observed during follow-up. All patients were followed up for an average period of 18 months (range=3-36 months). AVF was successfully used in 58 patients for hemodialysis, with primary access failure in 9 cases (5 cases in the treatment group and 4 cases in the control group) due to early thrombosis. The primary and secondary patency rates 12 months after surgery in the treatment group were 64 and 72%, respectively, and those in the control group were 60 and 76%, respectively. Patients with small caliber cephalic veins can be treated with radiocephalic fistula after the caliber of cephalic veins is expanded to more than 2.5 mm with a Fogarty catheter. The long-term patency rate awaits observation in a longer follow-up period.

Abstract
The Yellow River is the most important resource of water supply in northern China. The purpose of this work are to investigate the concentrations and potential ecological risk of heavy metals in the upper reaches of the Yellow River, the concentrations of eight heavy metals including As, Hg, Cd, Pb, Cr, Ni, Cu and Zn in filtered water and suspended particles from 12 sampling sites of Gansu, Ningxia and Inner Mongolia sections of the Yellow River of China were studied by atomic fluorescence spectrometry (AFS) and high resolution inductively coupled plasma mass spectrometer (HR-ICP-MS) in this paper. The results implied that all heavy metals in filtered water were lower than the limit standards for drinking water except for Cr (56.9 approximately 71. 5 microg L-1 ). Water quality parameters such as total nitrogen (TN), total phosphorus (TP) and pH were also determined and the contents were low along the river except for TN at S1 (2.48) and S9 (2.38), which exceeded the maximum permitted concentration of Class V for the protection of surface water. In suspended particles, the concentrations of Hg, Cd, Pb and Zn were much higher than those in the background value of soil from local section. Cluster analysis (CA) indicated that same sources for Ni, Cu, Cr, Zn and Pb could be stainless steel and petrochemical industrial activities, while As, Cd and Hg derived from agrochemicals, fertilizers, mining, fuel and coal combustion, respectively. Ecological risk assessment was undertaken using risk index (RI) for sampling sites and ecological risk factor (Er) for heavy metals. Eleven suspension samples existed considerable ecological risk (300.6< RI< 508. 6), while S1 was moderate ecological risk (RI, 299.3). According to Er, Hg had considerable or high ecological risk in Inner Mongolia section, while very high ecological risk for Cd at S11 (396.0), S9 (384. 0) and S5 (373. 3), respectively, implied a high pollution in these sampling sites. The results could provide reliable experimental data and theoretical basis for the relevant departments.

Abstract
OBJECTIVE To observe the clinical therapeutic effects of acupuncture at single point Shiqizhui (EX-B8) and multi-points in time-varying treatment for primary dysmenorrhea. METHODS 600 patients with primary dysmenorrhea were randomly assigned to the single point group (n=200) including group A (treating before the menstruation, n=100) and group B (immediately treating as soon as pain occurrence, n=100), the multi-points group (n=200) including group C (treating before the menstruation, n=100) and group D (immediately treating as soon as pain occurrence, n=100), or the control group, group E (n=200, no treatment). The therapeutic effects were analyzed after treatment for three menstrual cycles and interviewed for three follow-up periods. RESULTS Acupuncture could effectively relieve menstrual pain for primary dysmenorrhea compared with the control group (P<0.05, P<0.01). Immediate pain relief occurred following acupuncture within 5 min in group B (P<0.01) and group D (P<0.01), and the two groups obviously relieved menstrual pain for VAS scores. Both group A and group C obviously relieved menstrual pain (P<0.01), and group C was better than group A (P<0.05). Compared with group D, Group C was much better for CMSS scores in cycle 1. CONCLUSION Treating before the menstruation is better than immediately treating as soon as pain occurrence at the improvement in symptoms of dysmenorrheal at multi-points. And single point is better than multi-points when immediately treating as soon as pain occurrence. The present trial suggest Shiqizhui (EX-B8) should be chosen as a convenient point.

Abstract
In the present paper, high resolution inductively coupled plasma-mass spectrometry (HR-ICP-MS) was applied to analyse the contents of rare earth elements (REE) in the filtering water and suspensions from 12 sampling sites in Gansu, Ningxia and Inner Mongolia Sections of Yellow River, and the fractionation of REE in suspensions was also studied. The results demonstrated that the contents of REE in filtering water were very low, and the element with highest content of elements was La(32.0 ng x L(-1)). The average concentration of total REE (sigmaREE) in filtering water was 47.5 ng x L(-1), and the Baotou-Dengkou (S1) and Sanhuhekou (S2) sampling sites had a higher sigmaREE of 130.0 and 100.0 ng x L(-1), which implied that there might be external REE sources in the filtering water. And in suspensions, the average content of sigmaREE was 167.8 mg x kg(-1), which was similar to the Chinese soil background value. While the heavy rare earth elements (HREE) content in Shenchuanqiao (S11) of Gansu province were significantly higher than other stations, which indicated that it might have external HREE sources. The chondrite-normalized patterns of REE in suspensions from the study area were similar to that of Chinese soil, with light rare earth elements enrichment, and moderate Eu depletion and a bit of Ce depletion. It was showed that the contents of REE in suspensions were mainly from soil weathering.

Abstract
In the present paper, BCR sequential extraction and high resolution inductively coupled plasma-mass spectrometry (HR-ICP-MS) were performed to analyze the speciation contents of 14 kinds of rare earth elements (REE) in the surface sediments from 12 sampling sites (S1-S12) in Gansu, Ningxia and Inner Mongolia Sections of Yellow River, and REE fractionation were also studied. The results indicated that the contents of REE in 12 sediment samples werethe same order. The average contents of 14 rare earth elements were in this order: Ce(66.4)>La(35.8)>Nd(28.6)>Pr(7.88)>Sm(5.87) >Gd(5.01)>Dy (4.53)>Yb(2.86)>Er(2.51)>Eu(1.31)>Ho(0.856)>Tb(0.760)>Tm(0.428)>Lu(0.404), which were similar to the Chinese soil background. The residual fractions of all elements were present at the highest percentages(71.9%-93.9%), which indicated that the bioavailability or environmental impact was low. The percentage of reducible fraction was the lowest, ranged from 0. 20% to 3. 87% with the mean value of 0.83%, while the oxidizable fraction percentage(7.61%) was close to acid-soluble fraction(7.69%). But in Maqu (S12), oxidizable percentage (16.1%) was significantly higher than the acid-soluble fraction (1.73%). Correlation analysis showed that there was a significant positive correlation between total organic carbon (TOC) content and oxidizable percentage, and the correlation coefficients were between 0.763 and 0.914. REE fractionation results showed that: the contents of REE in surface sediments of Gansu, Ningxia and Inner Mongolia Sections of Yellow River were mainly from soil weathering, with light-REE enrichment and Eu depletion. The chondrite-normalized curve implied that La and Ce in Jinshawan (S8) and Baotou-Dengkou (S1) and heavy REE at all the sampling points might have external REE sources.

Abstract
A bacterial strain BGI-1 was isolated from the gut of German cockroaches (Blattella germanica L.) and was identified as Bacillus subtilis based on 16S rDNA sequence and morphological, physiological, and biochemical characters. The strain BGI-1 inhibited the growth of Beauveria bassiana; the diameter of the inhibition zone exceeded 30 mm. Vesicles were observed in B. bassiana hyphae on the edge of the inhibition zone. Fermentation of BGI-1 reduced the conidial germination rate by 12%. Further studies demonstrated that B. bassiana infections in German cockroaches orally treated with the extracts of BGI-1 fermentation were significantly weakened. Cumulative mortality rate was 49.5% in the treatment group at the 20 d, while that of the control group was 62.3%. The study intends to understand the relationship between the intestinal flora and the cockroach. Those microbes with anti-entomopathogenic fungi activity might contribute to resisting the infection of pathogenic fungi.

Abstract
Background: This is the largest prospective cohort analysis to assess how dietary factors involved in one-carbon metabolism are associated with endometrial cancer incidence, using 26 years of follow-up data from the Nurses’ Health Study. Methods: The prospective cohort analysis of one-carbon metabolism dietary factors used the Cox proportional hazards model, and incorporated 788 incident endometrial cancer events from 1980 to 2006. Genotyping and unconditional logistic regression were performed on 572 endometrial cancer cases and their matched controls to examine 29 mostly non-synonymous single-nucleotide polymorphisms involved in one-carbon metabolism. Results: There were no significant dose–response relationships between intake of any of the one-carbon metabolism dietary factors and endometrial cancer incidence, but alcohol consumption of <1 drink a day was significantly protective (hazard ratio: 0.80; 95% CI: 0.68, 0.94). Those with the MTHFR 677 TT or MTHFR 1298 CC genotype had more protective associations for many of the dietary factors and endometrial cancer, but statistical power was limited in this analysis. Conclusion: Dietary levels of folate, choline, methionine, vitamin B2, vitamin B6 or vitamin B12 do not appear to influence endometrial cancer incidence. Moderate alcohol intake may protect against developing endometrial cancer.

Abstract
BACKGROUND This is the first prospective cohort analysis on the association between vitamin D and endometrial cancer incorporating time-varying predicted plasma 25-hydroxyvitamin D [25(OH)D]. METHODS The prospective cohort analysis of predicted 25(OH)D and total dietary vitamin D intake used the Cox proportional hazards model, and involved 644 incident endometrial cancer events from 1986 to 2006 in the Nurses' Health Study. Genotyping and unconditional logistic regression were carried out on 572 endometrial cancer cases and their matched controls on 12 single nucleotide polymorphisms (SNPs) in vitamin D-related genes. RESULTS There was no significant association between predicted 25(OH)D and endometrial cancer incidence, with the hazard ratio for the highest (versus the lowest) quintile of predicted 25(OH)D as 1.00 (95% CI 0.73-1.36) (p-trend = 0.33). There was also no significant association involving total dietary vitamin D. No significant associations between any of the vitamin D-related SNPs and endometrial cancer were observed. CONCLUSION Both predicted 25(OH)D and total dietary vitamin D intake were not associated with endometrial cancer incidence. These results suggest that vitamin D may not protect against the development of endometrial cancer. However, the low and narrow vitamin D exposure range in the cohort may limit generalizability of the results.

Abstract
BACKGROUND The use of general anaesthetics in young children and infants has raised concerns regarding the adverse effects of these drugs on brain development. Sevoflurane might have harmful effects on the developing brain; however, these effects have not been well investigated. METHODS Postnatal day 7 (P7) Sprague-Dawley rats were continuously exposed to 2.3% sevoflurane for 6 h. We used the Fox battery test and Morris water maze (MWM) to examine subsequent neurobehavioural performance. Cleaved caspase-3 and neuronal nitric oxide synthase (nNOS) were quantified by immunoblotting, and the Nissl staining was used to observe the histopathological changes in the hippocampus. RESULTS A single 6 h sevoflurane exposure at P7 rats resulted in increased cleaved caspase-3 expression and decreased nNOS levels in the hippocampus, and induced the loss of pyramidal neurones in the CA1 and CA3 subfields of the hippocampus at P7-8. These changes were accompanied by temporal retardation of sensorimotor reflexes. However, neither the Fox battery test at P1-21 nor the MWM test at P28-32 showed differences between the air- and sevoflurane-treated groups. CONCLUSIONS Although early exposure to sevoflurane increases activated caspase-3 expression and neuronal loss and decreases nNOS in the neonatal hippocampus, it does not affect subsequent neurobehavioural performances in juvenile rats.

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

Abstract
Human adenoviruses (HAdVs) are the etiologic agent of many human infectious diseases. The existence of at least 54 different serotypes of HAdVs has resulted in difficulties in clinical diagnosis. Acute respiratory tract disease (ARD) caused by some serotypes from B and C species is particularly serious. Hexon, the main coat protein of HAdV, contains the major serotype-specific B cell epitopes; however, few studies have addressed epitope mapping in most HAdV serotypes. In this study, we utilized a novel and rapid method for the modeling of homologous proteins based on the phylogenetic tree of protein families and built three-dimensional (3D) models of hexon proteins in B and C species HAdVs. Based on refined hexon structures, we used reverse evolutionary trace (RET) bioinformatics analysis combined with a specially designed hexon epitope screening algorithm to achieve high-throughput epitope mapping of all 13 hexon proteins in B and C species HAdVs. This study has demonstrated that all of the epitopes from the 13 hexon proteins are located in the proteins' tower regions; however, the exact number, location, and size of the epitopes differ among the HAdV serotypes.

Abstract
Inflammation caused by chronic hepatitis B virus (HBV) infection is associated with the development of cirrhosis and hepatocellular carcinoma; however, the mechanisms by which HBV infection induces inflammation and inflammatory cytokine production remain largely unknown. We analyzed the gene expression patterns of lymphocytes from chronic HBV-infected patients and found that the expression of ZFP36, an AU-rich element (ARE)-binding protein, was dramatically reduced in CD4(+) and CD8(+) T lymphocytes from chronic HBV patients. ZFP36 expression was also reduced in CD14(+) monocytes and in total PBMCs from chronic HBV patients. To investigate the functional consequences of reduced ZFP36 expression, we knocked down ZFP36 in PBMCs from healthy donors using siRNA. siRNA-mediated silencing of ZFP36 resulted in dramatically increased expression of multiple inflammatory cytokines, most of which were also increased in the plasma of chronic HBV patients. Furthermore, we found that IL-8 and RANTES induced ZFP36 downregulation, and this effect was mediated through protein kinase C. Importantly, we found that HBsAg stimulated PBMCs to express IL-8 and RANTES, resulting in decreased ZFP36 expression. Our results suggest that an inflammatory feedback loop involving HBsAg, ZFP36, and inflammatory cytokines may play a critical role in the pathogenesis of chronic HBV and further indicate that ZFP36 may be an important target for anti-inflammatory therapy during chronic HBV infection.

Abstract
We propose a statistical model for dissecting a multilocus genotypic value into its main (additive and dominant) effects and epistatic effects between different loci in a case-control association study. The model can discern four different kinds of epistasis, additive × additive, additive × dominant, dominant × additive, and dominant × dominant interactions. To test each kind of epistasis, a χ(2) test statistic was computed for a two by two contingency table derived from combined genotypes in both case and control groups. We derived an analytical approach for estimating the asymptotic distribution of the χ(2) test statistic for epistatic tests under the null hypothesis, with the result being consistent with that from Monte Carlo simulations. The new model was used to analyze a case-control data set for candidate gene studies of stroke, leading to the identification of several significant interactions between causal SNPs on this disease.

Abstract
The occurrence of polycyclic aromatic hydrocarbons (PAHs) in a domestic wastewater treatment plant (WWTP) was investigated in a 1 year period. In order to understand how PAHs were removed at different stages of the treatment process, adsorption experiments were conducted using quartz sand, kaolinite, and natural clay as inorganic adsorbents and activated sludge as organic adsorbent for adsorbing naphthalene, phenanthrene, and pyrene. As a result, the adsorption of PAHs by the inorganic adsorbents well followed the Langmuir isotherm while that by the activated sludge well followed the Freundlich isotherm. By bridging equilibrium partitioning coefficient with the parameters of adsorption isotherm, a set of mathematical models were developed. Under an assumption that in the primary settler PAHs removal was by adsorption onto inorganic particles and in the biological treatment unit it was by adsorption onto activated sludge, the model calculation results fairly reflected the practical condition in the WWTP.

Abstract
Abstract
Background: Recent evidences have suggested that there are a rare population of cells called cancer stem cells (CSCs) in breast cancer, which have the ability of extensive self-renewal and contribute to metastasis and treatment resistance. This study evaluated the effects of an mTOR inhibitor, RAD001 (Everolimus) on breast CSCs of primary breast cancer cells and 2 breast cancer cell lines (MCF-7, MDA-MB-231) in vitro. Methods: Primarily, we isolated primary breast cancer cells from the 1cm3 axenic tissue from breast cancer patients, which was been digested in collagenase typelV in 1-3 hours. After filtration, the cells from the organoid were plated in DMEM/F12(1:1) containing 10% FBS ,100U/ml penicillin,100µg/ml streptomycin and some growth factors overnight. The next day, we sorted CD44 +, CD24-/low, ESA + cells as breast CSCs by flow cytometry from primary breast cancer cells, breast cancer cell lines MCF-7 and MDA-MB-231. And then the three CSCs were treated with different concentrations of docetaxel alone(0,20µM,40µM,80µM, 160µM), mTOR inhibitor RAD001 alone (0,10nM,100nM,1µM,10µM), or in combination with docetaxel(20µM).the Inhibition of the drugs on different Breast CSCs was quantified by methyl thiazolyl tetrazolium (MTT) assay. All employed CSCs were divided into four groups, given respectively 24h treatment of RAD001(100nM), docetaxel(20µM), combination or contrals. Apoptosis and distribution of cell cycles were examined with flow cytometry. Experiments were performed in triplicate. Result: All three kinds of breast CSCs were resistant to the standard treatment doses of docetaxel in vitro(IC50=80 µM±5µM),compared with this drug inhibited normal breast cancer cell lines(IC50=16µM±2µM). Treatment with RAD001 resulted in growth inhibition of all employed CSCs in a dose-dependent manner, which is more effective than the treatment with docetaxel alone(P<0.001), and CSCs of MDA-MB-231 proved to be most sensitive to this drug(IC20=8nM).Combination studies showed that there was an additive growth inhibitory effect of a combination treatment on three CSCs in vitro compared with treatment with RAD001 alone (P<0.001)or docetaxel alone(P<0.001). In addition, an increase in G2-M cell cycle arrest were seen in the combination treatment group when compared with controls(P<0.05), suggesting that cell cycle arrest may contribute to the increased growth inhibitory effects of combination treatment seen in this study. In primary CSCs, combined treatment induced a mount-up population of early apoptosis, the phenomenon was not taken place in the treatment of RAD001 alone, however, it's no statistical significance(P>0.05).
Discussion: We conclude that RAD001 has more effective inhibitory effect than docetaxel, and enhances the cytotoxic effects of docetaxel in models of breast CSCs in vitro by inducing cell cycle arrest, indicating that combination treatment with RAD001 and docetaxel may be an efficient therapy for refractory and metastatic breast cancer. But the drug interaction of RAD001 and docetaxel in the clinical situation has to be evaluated in further studies.

Abstract
AIMS/HYPOTHESIS Evolving research suggests that common and rare alleles jointly constitute the genetic landscape of complex disease. We studied the association between 43 pathway-related candidate genes with 'intermediate phenotype' (i.e. corresponding plasma protein) and diabetic nephropathy in a customised microarray of 1,536 SNPs. METHODS In this case-control study of type 2 diabetic Chinese individuals with and without diabetic nephropathy, cases (n = 545) were defined on the basis of a spot urinary albumin/creatinine ratio (ACR) > 113 mg/mmol; the value for controls (n = 503) was ACR < 3.3 mg/mmol. Genotyping was performed using Illumina GoldenGate assay. RESULTS No single nucleotide polymorphism (SNP) remained significant in single locus analysis after correction for multiple testing. Therefore, we explored the best approximately 1% SNPs. Of these 13 SNPs, four clustered to a 5' end NADPH oxidase homologue 4 (NOX4) haplotype (GGCC frequency = 0.776) with estimated OR for diabetic nephropathy of 2.05 (95% CI 1.04-4.06) (heterozygous) and 2.48 (1.27-4.83) (homozygous) (p = 0.0055). The haplotype was correlated with plasma Cu/Zn superoxide dismutase (SOD) concentration, suggesting increased oxidative burden. Endothelin-1 SNP (rs1476046G>A, frequency = 0.252) was correlated with plasma C-terminal pro-endothelin-1 concentrations with an estimated OR for diabetic nephropathy of (heterozygous) 1.26 (0.96-1.66) and (homozygous) 1.87 (1.13-3.12) (p = 0.0072). Nitric oxide synthase 1 (NOS1) 5' haplotype (TGTC frequency = 0.38) also revealed a suggestive association with diabetic nephropathy: heterozygous 1.26 (0.95-1.67), homozygous 1.57 (1.04-2.35) (p = 0.0073). A rare NADPH oxidase homologue 1 (NOX1)-coding non-synonymous SNP (Arg315His, frequency = 0.006) was found exclusively among cases. CONCLUSIONS/INTERPRETATION Our preliminary observations suggest that common haplotypes from NOX4 and endothelin-1 SNP correlated with plasma Cu/Zn SOD and C-terminal pro-endothelin-1 concentrations, respectively, and might have conferred diabetic nephropathy susceptibility. Common NOS1 and rare NOX1 variants also revealed a suggestive association with diabetic nephropathy. Future studies to validate our observation are needed.

Abstract
A synthetic multi-epitope gene containing critical epitopes of the Japanese encephalitis virus (JEV) envelope gene was cloned into both prokaryotic and eukaryotic expression vectors. The recombinant plasmid and purified recombinant protein (heterologously expressed in Escherichia coli) were used as immunogens in a mouse model. The results indicate that both the recombinant protein and the DNA vaccine induce humoral and cellular immune responses. Neutralising antibody titres in mice in the pcDNA-TEP plus rEP group increased considerably relative to mice immunised using either pcDNA-TEP or rEP alone (P<0.05). Furthermore, the highest levels of interleukin (IL)-2, interferon-gamma and IL-4 were induced following priming with the DNA vaccine and boosting with the recombinant protein. Together these findings demonstrate that a DNA-recombinant protein prime-boost vaccination strategy can produce high levels of antibody and trigger significant T cell responses in mice, highlighting the potential value of such an approach in the prevention of JEV infection.

Abstract
AIMS To demonstrate ultrahigh-resolution, three-dimensional optical coherence tomography (3D-OCT) and projection OCT fundus imaging for enhanced visualisation of outer retinal pathology in non-exudative age-related macular degeneration (AMD). METHODS A high-speed, 3.5 mum resolution OCT prototype instrument was developed for the ophthalmic clinic. Eighty-three patients with non-exudative AMD were imaged. Projection OCT fundus images were generated from 3D-OCT data by selectively summing different retinal depth levels. Results were compared with standard ophthalmic examination, including fundus photography and fluorescein angiography, when indicated. RESULTS Projection OCT fundus imaging enhanced the visualisation of outer retinal pathology in non-exudative AMD. Different types of drusen exhibited distinct features in projection OCT images. Photoreceptor disruption was indicated by loss of the photoreceptor inner/outer segment (IS/OS) boundary and external limiting membrane (ELM). RPE atrophy can be assessed using choroid-level projection OCT images. CONCLUSIONS Projection OCT fundus imaging facilities rapid interpretation of large 3D-OCT data sets. Projection OCT enhances contrast and visualises outer retinal pathology not visible with standard fundus imaging or OCT fundus imaging. Projection OCT fundus images enable registration with standard ophthalmic diagnostics and cross-sectional OCT images. Outer retinal alterations can be assessed and drusen morphology, photoreceptor impairment and pigmentary abnormalities identified.
