JunLi Liu, Bing Zhang, ShuJun Song, Ming Ma, ShaoYan Si, YiHu Wang, BingXin Xu, Kai Feng, JiGong Wu, YanChuan Guo
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0099920
Abstract: Objective Collagen peptides (CP) compounds, as bone health supplements, are known to play a role in the treatment of osteoporosis. However, the molecular mechanisms of this process remain unclear. This study aimed to investigate the effects of bovine CP compounds on the proliferation and differentiation of MC3T3-E1 cells. Methods Mouse pre-osteoblast cell line MC3T3-E1 subclone 4 cells were treated with bovine CP compounds. Cell proliferation was analyzed by MTT assays and the cell cycle was evaluated by flow cytometry scanning. Furthermore, MC3T3-E1 cell differentiation was analyzed at the RNA level by real-time PCR and at the protein level by western blot analysis for runt-related transcription factor 2 (Runx2), a colorimetric p-nitrophenyl phosphate assay for alkaline phosphatase (ALP), and ELISA for osteocalcin (OC). Finally, alizarin red staining for mineralization was measured using Image Software Pro Plus 6.0. Results Cell proliferation was very efficient after treatment with different concentrations of bovine CP compounds, and the best concentration was 3 mg/mL. Bovine CP compounds significantly increased the percentage of MC3T3-E1 cells in G2/S phase. Runx2 expression, ALP activity, and OC production were significantly increased after treatment with bovine CP compounds for 7 or 14 days. Quantitative analyses with alizarin red staining showed significantly increased mineralization of MC3T3-E1 cells after treatment with bovine CP compounds for 14 or 21 days. Conclusions Bovine CP compounds increased osteoblast proliferation, and played positive roles in osteoblast differentiation and mineralized bone matrix formation. Taking all the experiments together, our study indicates a molecular mechanism for the potential treatment of osteoarthritis and osteoporosis.
Regulation of Wnt signaling by nociceptive input in animal models
Yuqiang Shi, Subo Yuan, Bei Li, Jigong Wang, Susan M. Carlton, Kyungsoon Chung, Jin-Mo Chung, Shao-Jun Tang
Molecular Pain , 2012, DOI: 10.1186/1744-8069-8-47
Abstract: Fluorescent immunostaining results indicate that β-catenin, an essential protein in the canonical Wnt signaling pathway, is expressed in the superficial layers of the mouse SCDH with enrichment at synapses in lamina II. In addition, Wnt3a, a prototypic Wnt ligand that activates the canonical pathway, is also enriched in the superficial layers. Immunoblotting analysis indicates that both Wnt3a a β-catenin are up-regulated in the SCDH of various mouse pain models created by hind-paw injection of capsaicin, intrathecal (i.t.) injection of HIV-gp120 protein or spinal nerve ligation (SNL). Furthermore, Wnt5a, a prototypic Wnt ligand for non-canonical pathways, and its receptor Ror2 are also up-regulated in the SCDH of these models.Our results suggest that Wnt signaling pathways are regulated by nociceptive input. The activation of Wnt signaling may regulate the expression of spinal central sensitization during the development of acute and chronic pain.

CT Morphometric Analysis to Determine the Anatomical Basis for the Use of Transpedicular Screws during Reconstruction and Fixations of Anterior Cervical Vertebrae
Chun Chen, Dike Ruan, Changfu Wu, Weidong Wu, Peidong Sun, Yuanzhi Zhang, Jigong Wu, Sheng Lu, Jun Ouyang
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0081159
Abstract: Background Accurate placement of pedicle screw during Anterior Transpedicular Screw fixation (ATPS) in cervical spine depends on accurate anatomical knowledge of the vertebrae. However, little is known of the morphometric characteristics of cervical vertebrae in Chinese population. Methods Three-dimensional reconstructions of CT images were performed for 80 cases. The anatomic data and screw fixation parameters for ATPS fixation were measured using the Mimics software. Findings The overall mean OPW, OPH and PAL ranged from 5.81 to 7.49 mm, 7.77 to 8.69 mm, and 33.40 to 31.13 mm separately, and SPA was 93.54 to 109.36 degrees from C3 to C6, 104.99 degrees at C7, whereas, 49.00 to 32.26 degrees from C4 to C7, 46.79 degrees at C3 (TPA). Dl/rSIP had an increasing trend away from upper endplate with mean value from 1.87 to 5.83 mm. Dl/rTIP was located at the lateral portion of the anterior cortex of vertebrae for C3 to C5 and ipsilateral for C6 to C7 with mean value from ?2.70 to ?3.00 mm, and 0.17 to 3.18 mm. The entrance points for pedicular screw insertion for C3 to C5 and C6 to C7 were recommended ?2~?3 mm and 0–4 mm from the median sagittal plane, respectively, 1–4 mm and 5–6 mm from the upper endplate, with TPA being 46.79–49.00 degrees and 40.89–32.26 degrees, respectively, and SPA being 93.54–106.69 degrees and 109.36–104.99 degrees, respectively. The pedicle screw insertion diameter was recommended 3.5 mm (C3 and C4), 4.0 mm (C5 to C7), and the pedicle axial length was 21–24 mm for C3 to C7 for both genders. However, the ATPS insertion in C3 should be individualized given its relatively small anatomical dimensions. Conclusions The data provided a morphometric basis for the ATPS fixation technique in lower cervical fixation. It will help in preoperative planning and execution of this surgery.
Software Industry Cluster be Disagreement on Theory and Practice  [PDF]
Yang Wang, Luqian Wang
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.210069
Abstract: In the view of traditional industry cluster theory, it is easy to copy the software industry cluster pattern, or it is easy to copy another Silicon Valley, due to low reliability of the resources and the guidance factors of locations in software industry. But it is much more difficult to copy a Silicon Valley mode practically than imaginatively and the difficulties of bringing up and supporting high-tech initiatives is more than theoretic anticipation. In China, the software companies have just gathered together geographically and therefore no initiative center can be formed. All these above signify that software industry cluster is distinct from the traditional industry clusters, but the cognition of the reasons of software industry cluster is not clear yet. Furthermore, reasonable explanations of the bewilderment in the economical practice of software industry cluster are urgently needed.

Yang Wang, Luqian Wang
iBusiness (IB) , 2010, DOI: 10.4236/ib.2010.24049
Abstract: Based on the direction of the international FDI changed, from manufacturing to service industries, we should concern about the influence of the introduction of China’s logistics industry FDI to the national economy. The paper sets up regression model to examine logistics FDI and GDP in two aspects of time series and growth rate, we find that the logistics FDI reaches a high correlation with GDP, and logistics FDI is one of the major driving forces of economic development. Therefore, China should expand the introduction of logistics FDI, improve the quality of foreign investment, develop the positive economic growth effect of logistics FDI and promote the change of China’s economic growth pattern to ensure the development of China’s economy.

Jinliang Wang, Haizhen Wang
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.24056
Abstract: Based on theories and previous studies on online communication, we proposed two hypotheses to better under- stand the effects of online communication on subjective well-being with a sample of Chinese adolescents (n = 190). The results of liner regression analysis found that online communication was positively related to adoles- cents’ subjective well-being. For boys, the coefficient of determination of online communication on subjective well-being was .143, and for girls the coefficient of determination was .040, indicating that boys benefit more from online communication than do girls.

Jue Wang, Fenwei Wang
Journal of Cancer Therapy (JCT) , 2011, DOI: 10.4236/jct.2011.24064
Abstract: Background: The objective of this study was to evaluate the impact of radical prostatectomy on carcinosarcoma of the prostate. Methods: Patients diagnosed with carcinosarcoma of the prostate from 1977 through 2007 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Outcomes were examined with Kaplan-Meier survival analysis and Cox models. The association between clinical and demographic characteristics and survival of carcinosarcoma of the prostate was examined. Results: A total of fifty-four cases of histology confirmed carcinosarcoma of the prostate were identified. Median age of the patients was 74 years (range 28 - 94). Of the patients with a known tumor stage, all but one patient had a locally advanced or distant stage; all of the patients with known histology grade had poorly or undifferentiated histology. Twenty (37%) patients underwent transurethral resection only and Fourteen (25.9%) patients underwent radical prostatectomy. Eight (14%) patients received radiation therapy in combination with surgery. The median cancer specific survival was 16 months (95% CI 0 - 32 months). 1-, 3-, and 5- year cancer specific survival rate were 55.1%, 32.3% and 21.1%. In a multivariate analysis, radical prostatectomy was found to be a significant prognostic factor for cancer-specific survival. Conclusions: Carcinosarcoma of the prostate commonly occurs in older patients and associated with aggressive disease and poor prognosis. Radical prostatectomy is the only treatment modality that significantly improves survival. Emphasis on early diagnosis and detection and multimodality therapy of this disease is needed to improve the outcome for patients with this malignancy.
A Research on the Relationship between FDI and Jiangsu’s Regional Economy Disparity  [PDF]
Baoqian Wang, Cheng Wang
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.33018
Abstract: Through reading and summarizing relevant articles, the authors analyze two different kinds of effects that FDI influence the regional economy. Location and digesting ability reflects such non-equilibrium. By using regression analysis, the authors discover, in south Jiangsu, which the unit FDI increase contributes most to the GDP development, with middle and north Jiangsu lagging behind. The regression coefficient is 1.198, 0.429 and 0.572 respectively. Considering the index of digestion ability, unit FDI increase and unit GDP contribution rate still share strong relevant relationship. However, the coefficients change. The effects that FDI stimulate GDP growth are weakened, been made up by the endogenous ability. The granger test shows that in south Jiangsu, there exists a cycle of accumulative effect, namely both the FDI increase and the GDP growth do well with each other. However, in the rest of Jiangsu province, such effect is not obvious. Considering the elements of location and digesting ability, this paper offers tactics for Jiangsu for a better coordinate of future development.
Causes of and Remedies for Chinglish in Chinese College Students’ Writings  [PDF]
Ping Wang, Weiping Wang
Open Journal of Modern Linguistics (OJML) , 2012, DOI: 10.4236/ojml.2012.22009
Abstract: Based on Interlanguage Theory and other theories, this study examines data from samples of Chinese college students’ writings and interviews with the students to explore the causes of and remedies for Chinglish (a term used to refer English with Chinese characteristics). It claims that Chinglish is mainly caused by syntactic transfer from Chinese, the influence of Chinese thought patterns, inadequate exposure to authentic English and insufficient practice in English writing. The interviews with the students showed that the proportion of L1 thinking decreased with the writer’s L2 development. The recommended remedies for Chinglish include raising students’ awareness of distinctions between English and Chinese, increasing their exposure to authentic English and practice in English writing, and adjusting their thought patterns.
