Objective To determine main factors associated with quality of life in epileptics in northen China especially seizure severity and stigma, and the variations between men and women. Methods All patients with epilepsy aged 18-65 years were selected from the First Affiliated Hospital of China Medical University, tested from March 2014 to March 2015. All of them completed the general social science data, the Quality of Life Inventory in Epilepsy-31 (QOLIE-31), Liverpool Adverse Events Profile (LEAP), the National Hospital Seizure Severity Scale (NHS3), Epilepsy Stigma Scale (ESS), Self-rating Anxiety Scale ( SAS) and Hamilton Depression Scale ( HAMD) assessment. Results A total of 123 patients with epilepsy (60 men, 63 women) were interviewed. QOLIE-31 scores were 55. 81 ± 10. 17 in female patients, 65. 35 ± 10. 89 in male patients, the difference being statistically significant (t=2. 90, P<0. 05). ESS (1(0,2)), SAS(31. 85 ± 8. 16), HAMD (4. 38 ± 2. 90) scores of female patients were higher than that of male patients (0(0,0), 26. 93 ± 3. 45, 2. 80 ± 1. 39;U= -2. 710, t=2. 48, 2. 20, all P<0. 05). Multiple factors analysis and multiple stepwise regression analysis on quality of life revealed that depression (β= -0. 516, P<0. 01) and the severity of epilepsy (β= -0. 338, P=0. 01) were two strong predictors of QOLIE-31 overall scores. The linear regression showed that there was a direct link between shame and degree of depression (β = 0. 515, P= 0. 001 ) . Conclusions The main factors affecting the quality of life in epileptics in northen China are depression and seizure severity. Compared with male patients, female patients have a lower quality of life, and poorer psychological status, such as shame, depression and anxiety. There is a direct link between shame and depression in epileptics.

Objective To study the effects of the inhibition of nuclear factor kappa-B ( NF-κB) , on the hepatic heat shock protein 70 (HSP70) expression as well as on the changes of hepatic function and ultrastructure in a rodent model of hemonhageic shock. Method Hemorrhagic shock was produced by inducing bilateral femoral fractures in male Wistar rats. Intraperitoneal injection of pyrrolidine dithiocarbamate(PDTC)was used to inhibit NF-κB activation 1 hour before induction of shock. A total of 66 adult male Wistar rats were randomly divided into 3 groups: control group (Control, n = 6), trauma shock (TS, n = 30), and NF-κB inhibition followed by trauma shock (NF-κB inhibition, n =30). Measurements of hepatic NF-KB and HSP70, hepatic function bio-markers, TNF-α and IL-6 were obtained 0.5, 2, 4, 6, 8 hours after trauma. Histopathological changes in liver tissues were also noted. Hepatic expression of NF-κB was determined by using electrophoretic mobility shift assay, while HSP70 was assayed by western blot and analyzed with computer imaging. Results In rats with trauma shock, both hepatic NF-κB activity and HSP70 expression increased significantly compared to the control group, reaching peaks at 6 hour post injury. Serum alanine transferase (ALT) and total bilirubin (TB) also rose significantly,reaching peaks at 8 hours post trauma. Light microscopy revealed hepatic congestion with infiltration of inflammatory cells into hepatic sinusoid in the TS group at 8 hours. Inhibiting the activity of NF-κB one hour before trauma significantly decreased expression of HSP70 at 6 hours post trauma [16.9±4.4 (NF-κB inhibition) vs. 23.0±1.7 (TS), P ＜ 0.05]. In addition,levels TNF-α and IL-6 in the liver tissue also decreased, and hepatic congestion as well as hepatic cell degeneration were ameliorated, showing minimal inflammatory infiltrates in the hepatic sinusoids. NF-κB inhibition also significantly lowered the levels of ALT and TB at 4 hours post trauma [ALT, 540.8 ±66.2 nmol/L (NF-KB inhibition) vs. 640.6±80.2 nmol/L (TS), P ＜ 0.05; TB,2.3±0.3 mol/L (NF-κB inhibition) vs. 4.7 ±1.1 mol/L (TS), P ＜ 0.05]. Conclusions NF-κB and HSP70 are involved in the pathogenesis of hepatic injury during hemorrhagic shock, and the degree of NF-κB activity and HSP70 expression may be consistent with the extent of hepatocellular damage. Inhibition of NF-κB helps ameliorate liver injury due to trauma shock.

BACKGROUND:Conventional imaging method has significant limitations in the diagnosis of knee meniscus injury, which is difficult to detect the ful extent of the knee meniscus. OBJECTIVE:To evaluate the knee meniscus injury with magnetic resonance imaging. METHODS:The knee meniscus injury patients diagnosed with clinical treatment were retrospectively analyzed, and the characteristics of the magnetic resonance imaging were analyzed and graded. Then, the meniscus injury was analyzed and compared with the arthroscopic or surgical results. RESUTLS AND CONCLUSION:In the magnetic resonance imaging of knee meniscus injury, the Ⅰ level knee meniscus injury was presented as the punctate or round high signal that did not contacted with the surface of the meniscus, Ⅱ level knee meniscus injury was presented as the horizontal or oblique line or strip-like high signal in the meniscus, and Ⅲ level knee meniscus injury was presented as lines and complex high signal in the meniscus that extended to the articular surface of the meniscus, and accompanied with morphological changes of the meniscus. Magnetic resonance imaging, as a noninvasive checking method, can clearly show the meniscal degeneration and tearing, and correctly diagnosed the location, shape and severity of meniscus injury, which has significant guiding value in determine the clinical treatment options.

Objective:This study aimed to clarify the correlation of SPRY4-IT1 expression with the clinicopathological character-istics and prognosis of patients with esophageal squamous cell carcinoma (ESCC), as well as the role of SPRY4-IT1 in promoting ES-CC cell growth. Methods:Quantitative real-time polymerase chain reaction for SPRY4-IT1 expression was performed on 50 paired can-cerous and adjacent non-cancerous esophageal specimens. Small interfering RNA was used to suppress SPRY4-IT1 expression to fur-ther explore its role in tumor progression. Cell viability was tested in vitro by MTT assay (OD=490 nm), and cell apoptosis and cell cy-cle were investigated by flow cytometry. Results:We found markedly elevated SPRY4-IT1 expression in cancerous tissues compared with adjacent non-cancerous tissues (90%, P<0.01). Relative SPRY4-IT1 expression levels were correlated with some clinicopathologi-cal characteristics, such as tumor size (χ2=5.333, P=0.021), elevated TNM (2009) stage classi fi cation (χ2=5.556, P=0.018), and de-creased overall survival rates (χ2=5.296, P=0.021). SPRY4-IT1 expression level was not correlated with patient age, gender, smoking status, or alcohol consumption (all P>0.05). Further experiments showed that SPRY4-IT1 expression levels were significantly higher in three ESCC cell lines than in the normal human esophageal epithelial cell line Het-1A. In vitro assays of the ESCC cell line KYSE30 demonstrated that knockdown of SPRY4-IT1 expression by small interfering RNA reduced cell growth, mediated cell cycle arrest at the G0-G1 phase, and promoted cell apoptosis (all P<0.01). Conclusion:SPRY4-IT1 was overexpressed in ESCC tissues and ESCC cell lines and promoted the growth of ESCC cells. The dysregulated expression of long non-coding RNA SPRY4-IT1 may play an important role in the process of ESCC development and may be developed as a useful biomarker for the diagnosis and prognosis of ESCC.
