Abstract
OBJECTIVE The study was aimed at evaluating the in vitro cytotoxicity of some commonly used drugs in ophthalmology. Hydrocortisone sodium succinate, Dexamethasone sodium phosphate, 5-Fluorouracil, Tobramycin and Pilocarpine nitrate are frequently used in various indications involving eye care, and the aim was to test the safety of these in cell culture. MATERIALS AND METHODS The in vitro cytotoxicity was carried out on the NIH 3T3 cell line by the Sulforhodamine B (SRB) assay. RESULTS With the exception of 5-Fluorouracil, none of the other drugs demonstrated appreciable cytotoxicity up to high concentrations of 200 µg/ml at 48 hours of drug exposure. CONCLUSIONS Hydrocortisone sodium succinate, Dexamethasone sodium phosphate, Tobramycin and Pilocarpine nitrate were confirmed to be non-cytotoxic while 5-Fluorouracil was highly cytotoxic especially at 48 hours at very low concentrations.

Abstract
The T-cell immunoglobulin and mucin domain (TIM) family is associated with autoimmune
diseases, but its expression level in the immune cells of systemic lupus
erythematosus (SLE) patients is not known. The aim of this study was to investigate
whether the expression of TIM-3 mRNA is associated with pathogenesis of SLE.
Quantitative real-time reverse transcription-polymerase chain reaction analysis
(qRT-PCR) was used to determine TIM-1, TIM-3, and TIM-4 mRNA expression in peripheral
blood mononuclear cells (PBMCs) from 132 patients with SLE and 62 healthy controls.
The PBMC surface protein expression of TIMs in PBMCs from 20 SLE patients and 15
healthy controls was assayed by flow cytometry. Only TIM-3 mRNA expression decreased
significantly in SLE patients compared with healthy controls (P<0.001). No
significant differences in TIM family protein expression were observed in leukocytes
from SLE patients and healthy controls (P>0.05). SLE patients with lupus nephritis
(LN) had a significantly lower expression of TIM-3 mRNA than those without LN
(P=0.001). There was no significant difference in the expression of TIM-3 mRNA within
different classes of LN (P>0.05). Correlation of TIM-3 mRNA expression with serum
IgA was highly significant (r=0.425, P=0.004), but was weakly correlated with total
serum protein (rs=0.283, P=0.049) and serum albumin (rs=0.297,
P=0.047). TIM-3 mRNA expression was weakly correlated with the Systemic Lupus
Erythematosus Disease Activity Index (SLEDAI; rs=-0.272, P=0.032). Our
results suggest that below-normal expression of TIM-3 mRNA in PBMC may be involved in
the pathogenesis of SLE.

Abstract
Estrogen receptor α (ERα) is initially expressed in the majority of breast cancers and promotes estrogen-dependent cancer progression by regulating the transcription of genes linked to cell proliferation. ERα status is of clinical importance, as ERα-positive breast cancers can be successfully treated by adjuvant therapy with antiestrogens or aromatase inhibitors. Complications arise from the frequent development of drug resistance that might be caused by multiple alterations, including components of ERα signaling, during tumor progression and metastasis. Therefore, insights into the molecular mechanisms that control ERα expression and stability are of utmost importance to improve breast cancer diagnostics and therapeutics. Here we report that the atypical E3 ubiquitin ligase RNF31 stabilizes ERα and facilitates ERα-stimulated proliferation in breast cancer cell lines. We show that depletion of RNF31 decreases the number of cells in the S phase and reduces the levels of ERα and its downstream target genes, including cyclin D1 and c-myc. Analysis of data from clinical samples confirms correlation between RNF31 expression and the expression of ERα target genes. Immunoprecipitation indicates that RNF31 associates with ERα and increases its stability and mono-ubiquitination, dependent on the ubiquitin ligase activity of RNF31. Our data suggest that association of RNF31 and ERα occurs mainly in the cytosol, consistent with the lack of RNF31 recruitment to ERα-occupied promoters. In conclusion, our study establishes a non-genomic mechanism by which RNF31 via stabilizing ERα levels controls the transcription of estrogen-dependent genes linked to breast cancer cell proliferation.

Abstract
INTRODUCTION Posterior hemivertebra resection combined with multisegmental or bisegmental fusion has been applied successfully for congenital scoliosis. However, there are several immature bones and their growth can be influenced by long segmental fusion in congenital patients. Posterior hemivertebra resection and monosegmental fusion was therefore suggested for treatment of congenital scoliosis caused by hemivertebra. METHODS Between June 2001 and June 2010, 60 congenital scoliosis patients (aged 2-18 years) who underwent posterior hemivertebra resection and monosegmental fusion were enrolled in our study. A standing anteroposterior x-ray of the whole spine was obtained preoperatively, postoperatively and at the last follow-up appointment to analyse the Cobb angle in the coronal and sagittal planes as well as the trunk shift. RESULTS The mean preoperative coronal plane Cobb angle was 41.6°. This was corrected to 5.1° postoperatively and 5.3° at the last follow-up visit (correction 87.3%). The compensatory cranial curve was improved from 18.1° preoperatively to 7.1° postoperatively and 6.5° at the last follow-up visit while the compensatory caudal curve was improved from 21.5° to 6.1° after surgery and 5.6° at the last follow-up visit. The mean sagittal plane Cobb angle was 23.3° before surgery, 7.3° after surgery and 6.8° at the last follow-up visit (correction 70.1%). The trunk shift of 18.5mm was improved to 15.2mm. CONCLUSIONS Posterior hemivertebra resection and monosegmental fusion seems to be an effective approach for treatment of congenital scoliosis caused by hemivertebra, allowing for excellent correction in both the frontal and sagittal planes.

Abstract
BACKGROUND AND PURPOSE MR imaging-guided focused sonography surgery is a new stereotactic technique that uses high-intensity focused sonography to heat and ablate tissue. The goal of this study was to describe MR imaging findings pre- and post-ventralis intermedius nucleus lesioning by MR imaging-guided focused sonography as a treatment for essential tremor and to determine whether there was an association between these imaging features and the clinical response to MR imaging-guided focused sonography. MATERIALS AND METHODS Fifteen patients with medication-refractory essential tremor prospectively gave consent; were enrolled in a single-site, FDA-approved pilot clinical trial; and were treated with transcranial MR imaging-guided focused sonography. MR imaging studies were obtained on a 3T scanner before the procedure and 24 hours, 1 week, 1 month, and 3 months following the procedure. RESULTS On T2-weighted imaging, 3 time-dependent concentric zones were seen at the site of the focal spot. The inner 2 zones showed reduced ADC values at 24 hours in all patients except one. Diffusion had pseudonormalized by 1 month in all patients, when the cavity collapsed. Very mild postcontrast enhancement was seen at 24 hours and again at 1 month after MR imaging-guided focused sonography. The total lesion size and clinical response evolved inversely compared with each other (coefficient of correlation = 0.29, P value = .02). CONCLUSIONS MR imaging-guided focused sonography can accurately ablate a precisely delineated target, with typical imaging findings seen in the days, weeks, and months following the treatment. Tremor control was optimal early when the lesion size and perilesional edema were maximal and was less later when the perilesional edema had resolved.

Abstract
OBJECTIVE Since brain metastases (BM) is often accompanied by edema, and endostatin (ES) can prevent tumor tissue edema, we investigated the therapeutic effects of ES combined with radiotherapy in the treatment of BM of NSCLC. We also determined the patients who are suitable for this therapy. METHODS Eighty patients with BM of NSCLC were randomly divided into combination group and radiotherapy alone group. The primary endpoint was overall response rate, and secondary endpoints were overall survival time, cerebral edema index and adverse reactions. These were observed and the expressions of vascular endothelial growth factor receptor 2 (VEGFR2) protein and KDR gene in primary lesions were detected with immunohistochemical method and fluorescence in situ hybridization. RESULTS Compared with radiotherapy alone, brain edema was significantly reduced in the ES group (P = 0.003) without marked adverse reactions. For the overall response rate, there was no statistical significant difference between the two groups (control, 90 % vs. ES, 75 %, P = 0.07), but there was statistical significance in the patients with positive VEGFR2 (93 vs. 67.7 %, P = 0.012) or positive KDR gene (94.4 vs. 47.3 %, P = 0.002). In overall survival time, there was no statistical significance in the two groups (P = 0.35), in the tumors with positive VEGFR2 (P = 0.109) or with positive KDR gene (P = 0.147). CONCLUSION Compared with radiotherapy alone, ES combined with radiotherapy can reduce brain edema in NSCLC patients with BM and obtain better short-term response rate in tumors with positive VEGFR2 or positive KDR gene, but does not improve the overall survival.

Abstract
Curcumin, a natural anticancer agent, has been shown to inhibit cell growth in a number of tumor cell lines and animal models. We examined the inhibition of curcumin on cell viability and its induction of apoptosis using different gastric cancer cell lines (BGC-823, MKN-45 and SCG-7901). 3-(4,5-dimethyl-thiazol-2-yl)-2-5-diphenyltetrazolium-bromide (MTT) assay showed that curcumin inhibited cell growth in a dose- (1, 5, 10 and 30 μM) and time- (24, 48, 72 and 96 h) dependent manner; analysis of Annexin V binding showed that curcumin induced apoptosis at the dose of 10 and 30 μM when the cells were treated for 24 and 48 h. As cancers are caused by dysregulation of various proteins, we investigated target proteins associated with curcumin by two-dimensional gel electrophoresis (2-DE) and MALDI-TOF-TOF mass spectrometer. BGC-823 cells were treated with 30 μM curcumin for 24 h and total protein was extracted for the 2-DE. In the first dimension of the 2-DE, protein samples (800 μg) were applied to immobilized pH gradient (IPG) strips (24 cm, pH 3-10, NL) and the isoelectric focusing (IEF) was performed using a step-wise voltage ramp; the second dimension was performed using 12.5% SDS-PAGE gel at 1 W constant power per gel. In total, 75 proteins showed significant changes over 1.5-fold in curcumin-treated cells compared to control cells (Student's t-test, p<0.05). Among them, 33 proteins were upregulated and 42 proteins downregulated by curcumin as determined by spot densitometry. 52 proteins with significant mascot scores were identified and implicated in cancer development and progression. Their biological function included cell proliferation, cycle and apoptosis (20%), metabolism (16%), nucleic acid processing (15%), cytoskeleton organization and movement (11%), signal transduction (11%), protein folding, proteolysis and translation (20%), and immune response (2%). Furthermore, protein-protein interacting analysis demonstrated the interaction networks affected by curcumin in gastric cancer cells. These data provide some clues for explaining the anticancer mechanisms of curcumin and explore more potent molecular targets of the drug expected to be helpful for the development of new drugs.

Abstract
AIM Cost has been perceived to be a factor limiting the development of laparoscopic colorectal surgery. This study aimed to compare the costs of laparoscopic and open colorectal surgery. METHOD Patients undergoing laparoscopic or open elective colorectal surgery were recruited into a prospective study to evaluate the healthcare costs of each operative procedure in a district general hospital in England. All healthcare resources used (operation, hospital and community) were recorded and converted to costs in British pounds, 2006-2007. Costs of laparoscopic and open surgery were compared. RESULTS In all, 201 consecutive patients consented and were recruited (131 laparoscopic, 70 open). Operative costs were greater in the laparoscopic group (£2049 vs£1263, P < 0.001) due to the costs of disposable instruments, but the hospital costs were less (£1807 vs£3468, P < 0.001) due to longer lengths of stay in the open group. Community costs were similar in the two groups and had little impact on the overall costs, which were not significantly different (£3875 laparoscopic vs£4383 open, P = 0.308). In the subgroup of patients with a stoma, overall costs in the laparoscopic group are higher (not significant). CONCLUSION The costs of laparoscopic and open colorectal surgery are broadly equivalent. If there is an associated improvement in patient benefit, then laparoscopic colorectal surgery may be considered to be cost effective compared with open surgery.

Abstract
Antenatal clinics can expect at least one in five pregnant women to experience mental health problems, especially depression and anxiety. The present study aims to estimate the effects of the antenatal depressive and anxiety symptoms on pregnant, obstetric and neonatal outcomes. This was a prospective cohort study of 527 pregnancies and their neonates. Whether the women were with or without symptoms of depression and anxiety was determined by the Hospital Anxiety and Depression Scale (HADS). All the participants were followed to delivery. The prevalence of antenatal depressive and/or anxiety was 11.0%. The antenatal depressive and/or anxiety symptoms during pregnancy can increase the risk of prolonged pregnancy (RR =4.080, 95% CI: 1.249-13.325), especially in primiparous women.
