Jie Wang,Sheng Qing,Shunji Cui,Yanjuan Cui 한국로고스경영학회 2010 로고스경영연구 Vol.8 No.3

Corporate Social Responsibility (CSR) reporting system is the system to disclosure the institutions and organizations influence on the environment, economy and society to the public. It is a great improvement of CSR that has been issued by advanced enterprises. However the CSR development is still unbalance in China, half of them are in the initial stage. The whole level of CSR is not high and the disclosure breadth and depth are not deep to cover the stakeholder requirements and corporate value. There are lack of development in strategies and specific mechanisms of corporate implying CRS, while there are more improved spaces in the moral or voluntary implementation. In the practice of CRS, the corporate should fully consider the overall efficiencies of economy, society and environment, so that it is possible for CRS to develop sustainable. Therefore, Corporate should focus on the innovation of CSR process.

A cDNA encoding a cysteine protease inhibitor (CPI) was isolated from the cDNA library of clamworm Perinereis aibuhitensis Grube. The deduced amino acid sequence analysis showed that the protein had 51%, 48%, and 48% identity with Zgc: 153129 from Danio rerio, cystatin B from Theromyzon tessulatum, and the ChainA, stefin B tetramer from Homo sapiens, respectively. The gene was cloned into the intracellular expression vector pET-15b and expressed in Escherichia coli. The recombinant CPI (PA-CPI) was purified by affinity chromatography on Nicharged resin and ion-exchange chromatography on DEAE-Sepharose FF. The relative molecular mass of PACPI was 16 kDa as deduced by SDS-PAGE. Activity analysis showed that the recombinant protein could inhibit the proteolytic activity of papain. A constitutive and secretive expression vector was also constructed, and the cDNA encoding CPI was subcloned into the vector for extracellular expression. Western blotting analysis results showed that the PA-CPI was secreted into the medium. Bioassay demonstrated that E. coli DH5α harboring pUC18ompAcat-CPI showed a significant difference in mortality to the Asian longhorned beetle Anoplophora glabripennis compared with untransformed E. coli DH5α and control.

Objective: To analyze different fluid-fluid level features between benign and malignant bone tumors on magnetic resonance imaging (MRI). Materials and Methods: This study was approved by the hospital ethics committee. We retrospectively analyzed 47 patients diagnosed with benign (n = 29) or malignant (n = 18) bone tumors demonstrated by biopsy/surgical resection and who showed the intratumoral fluid-fluid level on pre-surgical MRI. The maximum length of the largest fluid-fluid level and the ratio of the maximum length of the largest fluid-fluid level to the maximum length of a bone tumor in the sagittal plane were investigated for use in distinguishing benign from malignant tumors using the Mann-Whitney U-test and a receiver operating characteristic (ROC) analysis. Fluid-fluid level was categorized by quantity (multiple vs. single fluid-fluid level) and by T1-weighted image signal pattern (high/low, low/high, and undifferentiated), and the findings were compared between the benign and malignant groups using the χ2 test. Results: The ratio of the maximum length of the largest fluid-fluid level to the maximum length of bone tumors in the sagittal plane that allowed statistically significant differentiation between benign and malignant bone tumors had an area under the ROC curve of 0.758 (95% confidence interval, 0.616–0.899). A cutoff value of 41.5% (higher value suggests a benign tumor) had sensitivity of 73% and specificity of 83%. Conclusion: The ratio of the maximum length of the largest fluid-fluid level to the maximum length of a bone tumor in the sagittal plane may be useful to differentiate benign from malignant bone tumors.

Background/Aims: Cigarette smoking is an important modifiable risk factor in kidney disease progression. However, the underlying mechanisms for this are lacking. This study aimed to assess whether nicotine (NIC), a major toxic component of cigarette smoking, would exacerbates tacrolimus (TAC)-induced renal in-jury. Methods: Sprague-Dawley rats were treated daily with NIC, TAC, or both drugs for 4 weeks. The influence of NIC on TAC-caused renal injury was examined via renal function, histopathology, oxidative stress, mitochondria, endoplasmic reticulum (ER) stress, and programmed cell death (apoptosis and autophagy). Results: Both NIC and TAC significantly impaired renal function and histopathology, while combined NIC and TAC treatment aggravated these parameters beyond the effects of either alone. Increased oxidative stress, ER stress, mitochondrial dysfunction, proinflammatory and profibrotic cytokine expressions, and programmed cell death from either NIC or TAC were also aggravated by the two combined. Conclusions: Our observations suggest that NIC exacerbates chronic TAC nephrotoxicity, implying that smoking cessation may be beneficial for transplant smokers taking TAC.

Zhang, Guo-Qing,Li, Fang,Sun, Sheng-Jie,Hu, Yi,Wang, Gang,Wang, Yu,Cui, Xiao-Xia,Jiao, Shun-Chang Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.4

Background: To investigate the clinical efficacy of expanded activated autologous lymphocytes (EAAL) in patients with small cell lung cancer (SCLC). Materials and Methods: A total of 32 SCLC patients were selected and randomly divided into EAAL treatment and control groups, 16 cases in each. EAAL were obtained by proliferation of peripheral blood mononuclear cells (PBMCs) of patients followed by phenotype determination. Clinical data of all patients were recorded. Patients of both groups were followed up and the overall survival (OS) were compared retrospectively. Results: After culture and proliferation in vitro, the percentages of $CD3^+$, $CD3^+CD8^+$, $CD45RO^+$, $CD28^+$, $CD29^+$, $CD8^+CD28^+$ and $CD3^+CD16^+/CD56^+$ cells increased markedly (p<0.05). The OS of the EAAL treatment group was longer than that of control group, but the difference was not statistically significant (p=0.060, HR=0.487, 95%CI 0.228~1.037). 1- to 3-year survival rates in EAAL treatment group were longer than those in control group, but there was still no significant difference (p>0.05). COX multivariate regression analysis showed that the number of chemotherapy cycles and the application of EAAL immunotherapy were independent prognostic factors for SCLC patients. The OS in females and chemotherapy${\leq}6$ cycles were obviously prolonged after EAAL immunotherapy. Conclusions: In vitro induction and proliferation of EAAL is easy and biologically safe. Generally, EAAL adoptive immunotherapy can evidently prolong the OS of SCLC patients.

Xie, Xiu-Zhen,Song, Kun,Cui, Baoxia,Jiang, Jie,Zhang, You-Zhong,Wang, Bo,Yang, Xing-Sheng,Kong, Bei-Hua Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.11

Objective: The aim of this retrospective study is to analyze the clinical and pathological factors related to the prognosis of Chinese patients with stage Ib to IIb cervical cancer. Methods and Results: 13 clinical pathological factors in 255 patients with stage Ib to IIb cervical cancer undergoing radical hysterectomy and systematic lymphadenectomy were analyzed to screen for factors related to prognosis. The cumulative 5-year survival of the 255 patients was 75.7%. The result of the univariate analysis suggested that clinical stage, cell differentiation, depth of cervical stromal invasion, parametrial tissue involvement, and lymph node metastasis were prognostic factors for patients with stage Ib to IIb cervical cancer (P<0.05). Compared with cases with involvement of iliac nodes, obturator nodes, or inguinal lymph nodes, cases with metastasis to the common iliac lymph nodes had a poorer prognosis (P<0.05). Cases with involvement of four or more lymph nodes had a poorer prognosis than those with involvement of three or fewer lymph nodes (P<0.05). Using multivariate Cox proportional hazards model regression analysis, non-squamous histological type, poor differentiation, parametrial tissue involvement, and outer 1/3 stromal invasion were found to be independently related to patients poor prognosis (P<0.05). Conclusion: Non-squamous histological type, poor cell differentiation, parametrial tissue involvement, and outer 1/3 stromal invasion are the independent poor prognostic factors for patients with stage Ib to IIb cervical cancer.

Ma, Zhi-Bin,Kong, Xiao-Lin,Cui, Gang,Ren, Cui-Cui,Zhang, Ying-Jie,Fan, Sheng-Jin,Li, Ying-Hua Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

Background: The aim of this study was to investigate differences of miRNA-34a expression in benign and malignant colorectal lesions. Materials and Methods: Samples of cancer, paraneoplastic tissues and polyps were selected and total RNA was extracted by conventional methods for real-time PCR to detect the miRNA-34a expression. In addition, the LOVO colorectal cancer cell line was cultured, treated with the demethylating agent 5-azacytidine and screened for differentially expressed miRNA-34a. Results: After the drug treatment, the miRNA-34a expression of colorectal cancer cell line LOVO was increased and real-time PCR showed that levels of expression in both cell line and colorectal cancer tissues were low, as compared to paraneoplastic tissue (p<0.05). Polyps tissues had significantly higher expression than paraneoplastic and colorectal cancer samples (p<0.05). Conclusions: miRNA-34a-5p may play a role as a tumor suppressor gene in colorectal cancer, with involvement of DNA methylation.

Shi-Ru Jia,Na-Chen,Yu-Jie Dai,Chang-Sheng Qiao,Jian-Dong Cui,Bo-Ning Liu 한국화학공학회 2009 Korean Journal of Chemical Engineering Vol.26 No.3

With CO2 and N2 as the pressure media, the effects of the moderate pressure (0.1-1.0MPa) and the holding time on the conductivities of the cell suspension of Saccharomyces cerevisiae CICC1447 and Saccharomyces cerevisiae CICC1339, as well as the absorbances of the supernatant (after centrifuged) at 280 nm (A280) and 260 nm (A260) were determined. The membrane permeability of Saccharomyces cerevisiae CICC1447 increased significantly and the cell leakage was aggravated with the pressure increase. For Saccharomyces cerevisiae CICC1339, the conductivity of the cell suspension, A280 and A260 of the supernatant fluctuated with the pressure increase; as a whole, they increased with pressure. Different from high pressure, a moderate pressure not only remarkably improved the permeability of the yeast cell membrane, but also kept yeast cell viability; moreover, the integrity of the yeast cell membrane could be maintained.

Purpose: The study was designed to: (1) investigate the prevalence of high-risk human papillomavirus (HR-HPV) infection and cervical neoplasia; and (2) evaluate clinical performance of visual inspection with acetic acid/ Lugol's iodine (VIA /VILI), Pap smear, high-risk human papillomavirus (HR-HPV) DNA test for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and (3) explore appropriate screening approach in rural areas of Shandong Province. Materials and Methods: A total of 3,763 eligible women from Yiyuan County in Yimeng mountainous areas of rural Shandong, China, were enrolled and underwent Pap smear, HR-HPV DNA testing by Hybrid Capture 2 (HC2), and VIA /VILI tests. Women positive in any test were referred to colposcopy and biopsy as indicated. Results: The prevalence of HR-HPV infection among all enrolled women was 11.1% and that in healthy women was 9.9%. In total 33 cases of CIN1, 16 cases of CIN2, 6 cases of CIN3 but none of cervical cancer were detected and the crude prevalence of CIN2+ was 0.58%. For detecting CIN2+, the sensitivity of HR-HPV DNA testing, VIA/VILI, Pap smear was 90.9%, 77.3%, 81.8%, respectively. Pap smear had the best specificity of 98.2%, followed by HR-HPV DNA testing with specificity of 89.4%, VIA/VILI had the lowest specificity of 81.2%. Colposcopy referral rate of HR-HPV DNA testing, VIA/VILI, Pap smear was 11.1%, 18.5%, 2.3%, respectively. Conclusions: Our results suggest that HR-HPV DNA testing alone might be appropriate for primary cervical cancer screening in rural low-resource areas of Shandong Province, China.
