Journal of Clinical Hepatology , 2013,
Abstract: ObjectiveTo investigate the effects of entecavir treatment on serum complement components, C3 and C4, in patients with hepatitis B cirrhosis and to determine their relation with treatment response. MethodsNinety-eight patients with hepatitis B cirrhosis who were treated with entecavir (10 mg orally once daily) for 48 weeks were enrolled in the study, and included 48 patients with decompensated cirrhosis and 50 patients with compensated cirrhosis. Blood samples from healthy blood donors were used as controls. The 98 cirrhosis patients were divided into three groups according to hepatitis B virus (HBV) DNA content at baseline (detected by real-time quantitative PCR): low-grade (103 to 105 IU/L); mid-grade (105 to 107 IU/L); high-grade (≥107 IU/L). Levels of C3 and C4 were detected by immunonephelometry, and of the liver function enzyme alanine aminotransferase (ALT) by automated biochemical analysis. Response to treatment was classified as: complete (ALT normalization, HBV DNA reduced to the lower limit of detection (<1000 U/L), and hepatitis B e antigen (HBeAg) seroconversion); partial (one or two of the complete response items achieved); unresponsive (none of the complete response items achieved). Significance of changes in levels before and after the treatment in the patients were assessed by single-factor analysis of variance; multiple group comparisons were made by least significant difference test, using Tamhane test for data that did not assume unequal variances. ResultsTreatment nave cirrhosis patients had significantly lower levels of C3 and C4 than healthy controls (P<0.01). The treatment nave patients with decompensated cirrhosis had significantly lower C3 and C4 levels than their counterparts with compensated cirrhosis (P<0.01). The treatment nave patients with low-level infection showed the lowest level of C3 (P<0.05). Twenty-nine patients acheived complete response, 69 achieved partial response, and there were no unresponsive cases. After treatment, the suppressed levels of C3 and C4 were relieved in the cirrhosis patients, but only the increase seen in the compensated cirrhosis patients was significantly different from the before treatment levels (P<0.01). Patients who achieved complete response had significantly higher C3 and C4 than those who achieved partial response both before and after treatment (P<0.01). Finally, the patients who achieved partial response only showed significantly increased levels of C3 in response to treatment (P<0.05). ConclusionEntecavir treatment increases the HBV-suppressed C3 and C4 in patients with cirrhosi
Construction of Comprehensive Development Index and Analysis on the Development Trend of Solar Energy Industry  [PDF]

Engineering (ENG) , 2018, DOI: 10.4236/eng.2018.108033
Abstract: As a strategic emerging industry, solar energy industry has been wished to ease the energy crisis and stimulate economic growth. In order to judge the development of the industry objectively, this paper constructs the index system of China’s solar energy industrial development from three dimensions of micro enterprise, medium industry and macroeconomic. This paper simultaneously takes 27 specific indicators, 54 listed companies and 10206 data from 2010 to 2016 as an example to calculate the industrial development index. The result reveals that with the implementation of the support policies playing a positive role in the development of China’s solar energy industry, the solar industry has steadily improved. Solar energy industry in our country is under the support of national support policies and its technological innovation capability is relatively active. However, the moderate investment and financing activities and inadequate enterprise operational capacity, to some extent, alleviate the development of the solar energy industry. The above shows that the solar energy industrial development index and its evaluation methods can help people to accurately grasp the development trend of the solar energy industry and accurately identify the development of advantages and disadvantages.
Systemic Delivery of Small Interfering RNA Targeting the Interleukin-2/15 Receptor β Chain Prevents Disease Progression in Experimental Arthritis
Tiantian Zhang, Xuehua Bai, Xiaohua Mao
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0078619
Abstract: The role of interleukin (IL)-15 in the pathogenesis of rheumatoid arthritis (RA) is well established; however, systemic knockdown of IL-15 receptor (IL-15R) for reduction in inflammation at local sites has not been demonstrated. In this study, the therapeutic effect of intravenously administered siRNA targeting the β chain of IL-15R which is shared by the receptor for IL-2 was examined in rats with adjuvant-induced arthritis (AA). Polyethylenimine (PEI)-complexed siRNA nanoparticles could easily accumulate in arthritic paws of AA rats. In the paws, the nanoparticles were avidly taken up by macrophages and to a lesser extent by T cells. Weekly administered IL-2/15Rβ siRNA polyplexes were capable of decreasing disease progression in AA rats, with striking inhibition of clinical, radiologic, and histologic features of RA. The observed therapeutic effect was associated with reduced expression of proinflammatory mediators in the inflamed joints. Thus, this study provides evidence that IL-2/15Rβ could be targeted for the treatment of RA.

Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.33068
Abstract:

Objectives: To evaluate the sensitivity and accuracy of the HPV DNA test in conjunction with thin prep cytology test as a screening method of human papillomavirus (HPV) infection. To study either the cervical erosion is related to high risk HPV infection or to determine the mean age distribution that is more prone to HPV infection. Material and Methods: The study is a retrospective cohort implemented to determine the real performance of liquid based medium and HPV DNA testing combined in second clinical hospital of Jilin University Changchun, China. The study group included total 150 patients from January 1, 2011 to December 30, 2012. A computerized search identified patients with thin prep test results and high risk HPV DNA testing during a 2-year period was recruited. The patients were chosen after proper speculum examination followed by thin prep cytology (TCT) and HPV DNA test. Cytologic specimens were obtained with endocervical brush, which was rinsed into the vial of Cytyc. The residual samples after the cytology report were taken for reflex HPV DNA test. The manufacture protocol was followed for HPV DNA testing using Hybrid Capture II. Colposcopic biopsy was performed for the diagnosis purpose, in patients who had atypical squamous cells of undeter-mined significance (AUS-US), low grade intraepithelial lesion (LSIL) or high-grade intraepithelial lesion (HSIL) in cytology and with positive results of highrisk HPV DNA. The diagnostic criteria were based on the Bethesda System (TBS). Findings: The high risk HPV positive women with abnormal cytology had a CIN I risk of 73 (86%), whereas 35 (23.3%) high-risk HPV positive women out of 109 (72.7%) normal cytology who underwent histological biopsy had CIN I 16 (10.7%). The risk for cervical intraepithelial neoplasia (CIN) in women with high-risk HPV positive with normal cytology was higher among women invited for the first time 31 - 40 years of age 12 (8%) than among older women 1 (0.7%). Out of 44 (29.3%) women who had I degree erosion with 6 (14%) positive HPV DNA test 38 (86%) had a normal histology biopsy showing no statically significant between them. Conclusion: The data confirm that HR-HPV DNA testing is much more sensitive than cytology alone and that HPV DNA testing helps in identifying women with high risk of serious cervical disease in an efficient and medically acceptable

Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-006-2083-3
Abstract: SnO2/TiO2 nanocomposite photocatalysts were prepared from TiCl4 and SnCl4·5H2O by supercritical fluid combination technique (SCFCT). This novel SCFCT is a combination of supercritical fluid drying method and sol-gel method. The XRD, TEM and FTIR results show that a new kind of active particle (Ti, Sn)O2 has formed and there is no sign of SnO2 crystals observed in the range of the doping concentration studied. The samples’ photocatalytic activity was evaluated by the degradation of acrylic acid. The results indicate that the SnO2/TiO2 nanocomposite photocatalysts prepared through SCFCT show significant improvement in catalytic activity as compared to pure TiO2 or SnO2/TiO2 catalysts prepared by traditional drying (TD). The effect of H2O2 (0.167 v%) on the photodegradation was also investigated. After the addition of H2O2, the chemical oxygen demand (COD) of acrylic acid, which had been treated with (15.1 mol%) SnO2/TiO2 nanocomposite photocatalysts for 3 h, was reduced from 400–500 to 20 mg/L.

International Journal of Reproduction, Contraception, Obstetrics and Gynecology , 2013, DOI: 10.5455/2320-1770.ijrcog20130903
Abstract: Background: The purpose of this study is to understand the incidence, related factors, and the prognosis factors in order to avoid risk, proper method of diagnosis and treatment and reduce complications and provide the basis. Methods: 85 Vulvar cancer (VC) patients treated in our hospital from 2002.10 to 2012.10 were collected and analyzed by retrospective comparative methods. SPSS19.0 application software was used for the statistical analysis. The clinical data are analyzed by chi-square and F test statistic methods. P < 0.05 was a significant difference between the judgment standard. Results: During 10 years, we treated 3391 cases of the primary malignant tumors including 85 VC cases; VC was 2.89% (85/3391). The age was between 24~88 years old, mean was 57.09±12.93 yrs. old, variable age of the VC had been juvenescence trend (F=6. 013, P=0.016). The differences between the urban and rural residential area have some influence to the onset of VC. Rural patients are more than urban patients. By statistical analysis, region distribution in these two groups was remarkably different=4.16,P=0.045<0.05, but the urban proportion of patients in different years has no difference (χ2=0.080, P=0.777). Conclusion: The number of cases increased progressively in young age. VC patients were more in rural area than urban. History of malignant tumor and obesity has the positive correlation with VC. High-risk groups should be alert to the possibility of VC. Preoperative diagnosis should be Colposcopic, biopsy in order to improve the accuracy of earlier diagnosis. Vulvar resects have an effect on the healing of the incision. Follow-up rate is low; It is difficult to say statistically survival rate is 5 years.

Journal of Animal Science and Biotechnology , 2012, DOI: 10.1186/2049-1891-3-24
Abstract: Background Complex vertebral malformation (CVM) and bovine leukocyte adhesion deficiency (BLAD) are two autosomal recessive lethal genetic defects frequently occurring in Holstein cattle, identifiable by single nucleotide polymorphisms. The objective of this study is to develop a rapid and reliable genotyping assay to screen the active Holstein sires and determine the carrier frequency of CVM and BLAD in Chinese dairy cattle population. Results We developed real-time PCR-based assays for discrimination of wild-type and defective alleles, so that carriers can be detected. Only one step was required after the DNA extraction from the sample and time consumption was about 2 hours. A total of 587 Chinese Holstein bulls were assayed, and fifty-six CVM-carriers and eight BLAD-carriers were identified, corresponding to heterozygote carrier frequencies of 9.54% and 1.36%, respectively. The pedigree analysis showed that most of the carriers could be traced back to the common ancestry, Osborndale Ivanhoe for BLAD and Pennstate Ivanhoe Star for CVM. Conclusions These results demonstrate that real-time PCR is a simple, rapid and reliable assay for BLAD and CVM defective allele detection. The high frequency of the CVM allele suggests that implementing a routine testing system is necessary to gradually eradicate the deleterious gene from the Chinese Holstein population.

Physics , 2008, DOI: 10.1080/09500340903254700
Abstract: In this paper, we will describe a new factorization algorithm based on the continuous representation of Gauss sums, generalizable to orders j>2. Such an algorithm allows one, for the first time, to find all the factors of a number N in a single run without precalculating the ratio N/l, where l are all the possible trial factors. Continuous truncated exponential sums turn out to be a powerful tool for distinguishing factors from non-factors (we also suggest, with regard to this topic, to read an interesting paper by S. Woelk et al. also published in this issue [Woelk, Feiler, Schleich, J. Mod. Opt. in press]) and factorizing different numbers at the same time. We will also describe two possible M-path optical interferometers, which can be used to experimentally realize this algorithm: a liquid crystal grating and a generalized symmetric Michelson interferometer.
