Abstract
Non-small cell lung cancer (NSCLC) is the major cause of cancer-related lethality among human cancer patients globally, and the poor prognosis of this cancer is mainly explained by metastasis, so it is essential to find out the molecule mechanisms and a novel therapeutic for NSCLC. A disintegrin and metalloprotease with thrombospondin motif 5 (ADAMTS5) belongs to the protease family. It has been reported to participate in tumor migration and invasion. In this study, we showed that the expression of ADAMTS5 was higher in lung cancer tissues by Western blot. The immunohistochemistry analysis was performed in 140 NSCLC cases, and the result indicated that ADAMTS5 was significantly associated with clinical pathologic variables. The Kaplan-Meier curve showed that the high expression of ADAMTS5 was related to poor prognosis of lung cancer patients. Wound healing assays and transwell migration assays revealed that the high expression of ADAMTS5 promoted the migration and invasion of NSCLC. In a word, our findings suggest that ADAMTS5 can regulate the migration and invasion of NSCLC and it may be a useful target of therapy in NSCLC.

Abstract
PURPOSE In this study, we investigated the expression and role of PSMB4 in human epithelial ovarian cancer(EOC). METHODS Western blot was used to evaluate the expression of PSMB4 in EOC tissues, and immunohistochemical analysis was performed on 115 cases of ovarian cancers. Then, we used Fisher exact test to analyze the correlation between PSMB4 and clinicopathological parameters. Starvation and re-feeding assay was used to assess cell cycle. CCK-8 assay and plate colony formation assay showed the influence of PSMB4 on proliferation of EOC cells. RESULTS The expression of PSMB4 in EOC tissues was higher than normal ovary tissues and was significantly associated with clinical pathologic variables. Kaplan-Meier curve showed that high expression of PSMB4 was related to poor prognosis of EOC patients. Starvation and re-feeding assay suggested that PSMB4 played a critical role in EOC cell proliferation. CCK-8 assay and plate colony formation assay showed that EOC cells treated with PSMB4-siRNA reduced cell proliferation of EOC cells. Additionally, PSMB4 knockdown decreased NF-κB activity. PSMB4 also regulated the expression of NF-κB mediated proteins, including cyclin D1, and cyclin E which involved in cell proliferation. CONCLUSIONS Our findings implied that PSMB4 is involved in the progression of EOC and could serve as potential therapeutical target of EOC. These data suggested that PSMB4 may promote cell proliferation via the NF-κB-target gene in EOC.

Abstract
PFTK1 was a cell division cycle 2-related serine/threonine protein kinase, which was up-regulated in breast cancer tissues and breast cancer lines. And up-regulated PFTK1 was highly associated with grade, axillary lymph node status, and Ki-67. Moreover, Kaplan-Meier curve showed that up-regulated PFTK1 was related to the poor breast carcinoma patients' overall survival. Here, we first discovered and confirmed that cyclin B was a new interacting protein of PFTK1, and the complex might increase the amount of DVL2, which triggers Wnt/β-catenin signaling pathway. Furthermore, knockdown of PFTK1 attenuated cell proliferation, anchorage-independent cell growth, and cell migration and invasion by inhibiting the transcriptional activation of β-catenin for cyclin D1, MMP9, and HEF1, whereas exogenous expression of PFTK1 might promote MDA-MB-231 cells proliferation, migration, and invasion via promoting PFTK1-DVL2-β-catenin axis. Our findings supported the notion that up-regulated PFTK1 might promote breast cancer progression and metastasis by activating Wnt signaling pathway through the PFTK1-DVL2-β-catenin axis.

Abstract
Melanoma associated antigen-A (MAGE-A) is an oncogene and correlated with tumor initiation and development. However the roles of MAGE-A9 in non-small cell lung cancer (NSCLC) are still unknown. We investigated MAGE-A9 mRNA expression in 18 tumor tissues of NSCLC by qRT-PCR and MAGE-A9 protein expression in 213 NSCLC samples of tissue arrays by immunohistochemical staining. We assessed the relationship between MAGE-A9 expression and clinical parameters. The results showed that the high expression of MAGE-A9 protein in NSCLC tumor cells were commonly present in squamous cell carcinomas (P = 0.030). It was also related to larger tumor diameter, lymph node metastasis and later stage grouping with TNM classification (all P < 0.05). Whereas the expression of MAGE-A9 in stromal cells was higher in squamous cell carcinomas as well. Cox regression univariate and multivariable analysis revealed that MAGE-A9 expression in tumor cells of NSCLC (P < 0.001) is an independent prognostic factor in five-year overall survival rate. We concluded that the molecular assessment of MAGEA9 could be considered to improve prognostic evaluation and to identify eligible patients for potential target therapy.

Abstract
We determined the expression of epithelial-mesenchymal transition (EMT) indicator proteins, E-cadherin (E-cad), vimentin (VIM), mucin 1 (MUC1) and S100 calcium-binding protein A4 (S100A4) in hepatocellular carcinoma (HCC) patient tissue samples. We also investigated the relationship between the expression of these proteins and clinicopathologic factors in HCC. Finally, we assessed the potential value of these markers as prognostic indicators of survival in HCC patients. The expression of E-cad, VIM, MUC1 and S100A4 EMT indicator proteins was assessed in tissue microarray HCC tissue sections and corresponding peritumoral normal tissues by immunohistochemistry. In addition, the expression for the four EMT indicator proteins was correlated with clinicopathological features of HCC and patient outcome. Comparison of clinicopathological characteristics and immunohistochemistry by χ(2) analysis revealed that downregulation of E-cad in HCC was significantly associated with later TNM cancer stage (P = 0.012), gross classification (P = 0.018), regional lymph node metastasis (P = 0.036) and liver cirrhosis (P = 0.028). Increased S100A4 expression in HCC was significantly associated with differentiation (P = 0.032), tumor with a complete fibrous capsule (P = 0.031) and portal vein invasion (P = 0.038). High VIM expression in HCC was significantly associated with high serum α-fetoprotein levels (P = 0.016). We also observed that low E-cad expression was significantly associated with overexpression of VIM (P = 0.001). Kaplan-Meier survival and Cox regression analysis revealed that low E-cad expression (HR = 0.164, 95 % CI 0.072 to 0.373, P < 0.001) and high serum α-fetoprotein levels (HR = 2.202, 95 % CI 1.054 to 4.598, P = 0.036) were independent prognostic factors in HCC. Our study demonstrates that high S100A4 and VIM expression and low E-cad expression correlate with an aggressive, malignant phenotype in HCC. These results also support a role for E-cad as a prognostic factor in HCC.

Abstract
Ring finger protein 1 (RING1) have recently been reported to be related to aggressive tumor features in Prostate Cancer and urothelial carcinoma of the bladder. However, the role of RING1 in non-small-cell lung cancer (NSCLC) tumorigenesis has never been elucidated. So we aimed at investigating the potential role of RING1 in NSCLC. RING1 expression was evaluated by Immunoblot in 8 paired fresh lung cancer tissues and immunohistochemistry on 69 paraffin-embedded sections from 2006 to 2009. Furthermore, flow-cytometry and RNA interference were performed to analyse the role of RING1 in A549 cells. We showed that the expression level of RING1 was significant increased in lung cancer as compared with the adjacent normal tissue. High expression level of RING1 was associated with TNM stage (P = 0.013), and RING1 was positively related with proliferation marker Ki67 (P < 0.05). Moreover, RING1 knockdown induces growth suppression of human lung cancer cells through G1/S cell cycle phase arrest in vitro. Kaplan-Meier survival curves showed that high expression level of RING1 was associated with poor prognosis (P = 0.03). On the basis of these results, we suggested that RING1 protein expression may be a favorable independent prognostic parameter for non-small cell lung cancer.

Abstract
Epithelial membrane protein 3 (EMP3) is a typical member of the epithelial membrane protein (EMP) family which has been reported to be a tumor suppressor gene in neuroblastomas and gliomas and recently reported to be commonly repressed in esophageal squamous cell carcinoma (ESCC) cell lines. However, the expression and clinical significance of EMP3 protein in lung cancer have not yet been elucidated. In this article, we detected that the expression of EMP3 in non-small cell lung cancer was significantly lower than the expression of normal lung tissues (P < 0.01) by western blot. EMP3 expression in Lung cancer was significantly related to p-TNM stage (P < 0.05) and EMP3 was negatively correlated with proliferation marker Ki67(r = -0.775; P < 0.01), However, no significant correlations were found between EMP3 and other clinical parameters. The post-recurrent survival after radical surgery was poorer in lung cancer patients with lower EMP3 expression (P < 0.01). While in vitro, following release from serum starvation of A549 NSCLC cell, the expression of EMP3 was deregulated. Thus, our finding suggests that EMP3 may be a tumor suppressor gene at the late step of lung cancer, and EMP3 may be a potential prognostic marker and therapeutic target of NSCLC.

Abstract
PURPOSE A small glutamine-rich tetratricopeptide repeat-containing protein alpha (SGTA) is a 35 kDa protein involved in a number of biological processes. However, the role of SGTA in non-small-cell lung cancer (NSCLC) tumorigenesis has never been elucidated. The purpose of this study was to determine whether SGTA could serve as a biomarker for stratification and prediction of prognosis in NSCLC. METHODS Small glutamine-rich tetratricopeptide repeat-containing protein alpha expression was evaluated by Western blot in 8 paired fresh lung cancer tissues and immunohistochemistry on 83 paraffin-embedded sections. The effect of SGTA was assessed by RNA interference in A549 cells. Serum starvation and refeeding, flow cytometry, CCK-8, and tunnel assays were performed. RESULTS Small glutamine-rich tetratricopeptide repeat-containing protein alpha was highly expressed in NSCLC and significantly correlated with NSCLC histological differentiation, clinical stage, and Ki-67. Multivariate analysis indicated that SGTA was an independent prognostic factor for NSCLC patients' survival. The present investigation demonstrated that suppression of SGTA expression resulted in a significant decline of proliferation in A549 cells. Besides, SGTA could abolish the toxicity of cisplatin in A549 cells. CONCLUSIONS These findings suggested that SGTA might play an important role in promoting the tumorigenesis of NSCLC, and thus be a promising therapeutic target to prevent NSCLC progression.

Abstract
Purpose To image SDS distribution across different skin regions, to compare the permeability difference between porcine and human skin, and to evaluate the interaction between SDS and skin. Methods Full thickness porcine and human skin was treated with acyl chain perdeuterated SDS (SDS-d25) at room temperature and at 34 °C for 3, 24 and 40 h. SDS distribution in skin was monitored by confocal Raman and IR microspectroscopic imaging. Permeation profiles of SDS-d25 in skin were derived from the band intensities of the CD2 stretching vibrations. The interaction between SDS and skin was monitored through the CH2 and CD2 stretching frequencies and the Amide I and II spectral region. Results SDS-d25 penetrates both porcine and human skin in a time and temperature-dependent manner, with slightly higher permeability through the stratum corneum (SC) in porcine skin. When SDS permeates into the SC, its chains are more ordered compared to SDS micelles. The secondary structure of keratin in the SC is not affected by SDS-d25. Conclusion The spatial distribution of SDS-d25 in skin was obtained for the first time. Infrared microscopic imaging provides unique opportunities to measure concentration profiles of exogenous materials in skin and offers insights to interaction between permeants and skin.

Abstract
PURPOSE To examine the relationship between corneal biomechanical properties and the degree of myopia. METHODS Chinese subjects (n=172, age: 11-65 years) were divided into diagnostic groups with non-myopia (spherical equivalence (SE)>-0.50 D), low (-3.00 ≤ SE ≤ -0.50 D), moderate (-6.00 ≤ SE < -3.00 D), and high myopia (SE<-6.00 D). Only the right eye of each subject was analyzed. Central corneal thickness (CCT) was measured by optical coherence tomography. An ocular response analyzer was used to measure corneal hysteresis (CH), corneal resistance factor (CRF), intraocular pressure (IOP), and corneal compensated IOP (IOPcc). Refraction was measured by both automated and subjective refractometry and expressed as SE. RESULTS CH was significantly lower in high myopia compared with both low and non-myopia (P ≤ 0.002). CCT was 1.5 times more correlated to CH variation compared with refraction. Similarly, CRF was four times more dependent on CCT than refraction. CH (P<0.001) or CRF (P=0.005) was positively correlated to refraction. Both IOP and IOPcc were negatively correlated to refraction (P<0.001), respectively. CONCLUSIONS CH decreases only in high myopia. Refraction is positively correlated to both CH and CRF but negatively correlated to both IOP and IOPcc. These results indicate that the mechanical strength in anterior segment of the eye is compromised in high myopia. In addition, high myopia may increase the risk of glaucoma.

Abstract
Our previous study demonstrated that the CYP2C9*3 gene variant was significantly associated with elevated plasma irbesartan concentration and blood pressure decline, assessed by a 4-week follow-up and revisit following daily administration of irbesartan. We conducted a further analysis to examine the acute effects of the CYP2C9 polymorphism on plasma concentration and blood pressure through remeasurement 6 h after administration of irbesartan. We used an extreme-sampling approach by selecting individuals from the top and bottom deciles of blood pressure response residuals to irbesartan from the previous study population in Anhui, Taihu, and Dongzhi Counties, in China. A total of 196 subjects were available for the analysis. Pre- and posttreatment systolic and diastolic blood pressures (SBP and DBP), and venous blood samples (0.5, 2, and 6 h following the first treatment) were collected from each individual. Plasma irbesartan concentrations were determined by a standard HPLC/fluorescence method. The observed frequencies were 97.7% for CYP2C9*1 (Ile359) and 2.3% for CYP2C9*3 (Leu359). Subjects with the CYP2C9*1/CYP2C9*3 genotype had significantly higher plasma irbesartan concentrations when compared with those with the CYP2C9*1/CYP2C9*1 genotype (beta +/- SE = 81 +/- 36) and greater DBP response (beta +/- SE = 5.6 +/- 2.5 mmHg) at the 6-h time point after adjusting for important confounders. Our finding suggests that the CYP2C9*3 gene variant significantly alters the plasma concentration and acute DBP response at the 6-h point following irbesartan treatment in Chinese hypertensive patients.

Abstract
OBJECTIVE To study the effect of transcatheter arterial chemoembolization (TACE) combined with beta-ultrasound guided portal vein embolization (PVE) through fine-needle liver puncture for hepatocellular carcinoma. METHODS 209 patients with primary hepatocellular carcinoma were divided into TACE group (104 patients) and TACE + PVE group (105 patients). RESULTS The response rates (CR + PR) were 37.5% in TACE group and 57.2% in TACE + PVE group (P < 0.01). Tumor thrombi became lessened or resolved in the portal vein with incidences of 22.2% in TACE group and 68.8% in TACE + PVE group (P < 0.01). The 1-, 2- and 3-year survival rates were 65.1%, 36.3% and 20.5% in TACE group and 95.6%, 59.6% and 39.1% in TACE + PVE group (P < 0.05). CONCLUSION The effect of TACE combined with PVE is much more effective than TACE alone for hepatocellular carcinoma. Beta-ultrasound guided portal vein embolization through fine-needle liver puncture is effective, easy, safe and should be widely practiced.

Abstract
After the Opium war, the aggressors, under the mask of missionaries, came to China by making use of western medicine as its tool for cultural invasion. This paper gives a description on the activities of all sects of Christianity and the institutions set up by them. Hospitals run by Christian Missions became the therapeutic institutions at all levels and made contributions to the prevention and treatment of diseases for local people.
