Objective To investigate the effects of antithyroid drug(ATD) on oxidative stress in Graves disease patients with and without infiltrative ophthalmopathy.Method The levels of superoxide dismutase(SOD),glutathione peroxidase(GPx) and catalase(CAT) in erythrocytes of Graves disease patients(18 with and 20 without infiltrative ophthalmopathy) were measured before and after treatment with ATD.Results Compared with the normal control group,the levels of SOD,GPx and CAT were significantly higher in Graves disease patients with and without infiltrative ophthalmopathy.After euthyroidism was achieved with the treatment of ATD,the levels of SOD,GPx and CAT were normalized in the patients without infiltrative ophthalmopathy,but oxidative stress was still present in the patients with infiltrative ophthalmopathy.Conclusion The oxidative stress is obvious in patients with Graves ophthalmopathy,which suggests that oxidative stress is involved in orbital inflammation.

Objective To investigate cortactin expression in malignant colorectal tissues and corresponding adjacent non-cancerous colon tissues,precancerous lesions (adenomatous polyps) and the relationship between the expression of cortactin and cell division in colorectal cancer cells.Methods The expression of cortactin was detected by immunohistochemistry in colorectal cancer,colorectal adenomatous polyp (precancerous lesions) and colorectal tissues adjacent to adenocarcinomas (normal tissues).Kaplan-Meier method was employed to compare the survival between the groups.Cortactin expression and cell division were detected by Western blot and immunofluorescence in SW-620 colon cancer cells treated with cortactin siRNA.Results The positive expression rate of cortactin was significantly higher in colorectal cancer tissues than in adenomatous polyp tissues and pericarcinomatous normal tissues.Overexpression of cortactin in colorectal cancer tissues was correlated with poor differentiation (P ＜ 0.01),lymph node metastasis (P =0.006),and TNM stage (P =0.022).The 5 year survival rate of the group of negative/weak positive expression of eortactin was significantly higher than the group of strong positive expression of cortactin.CTTN gene amplification in colorectal cancer tissues was obvious.Cortactin siRNA induction caused a lower cortactin protein expression in colorectal cancer cells.Conclusions It is suggested that the excessive expression of cortactin contributes to the growth of cancer cells in colorectal cancer.

Objective To establish a calculation method for the voiding work parameters by using the detrusor power curve and to evaluate its clinic efficacy.Methods From January 2001 to January 2011,132 male patients with benign prostate hyperplasia who underwent urodynamic tests were retrospectively reviewed.The patients' age ranged from 45 to 84 years old (mean 57 years old).All patients had no previous history of neurological disease and no positive findings in neurological examinations.The voiding work of bladder,the voiding power of bladder and voiding energy consumption were calculated by using the detrusor power curve method and the linearized passive urethral resistance relation analysis was conducted.According to the detrusor status,all patients were divided into the decreased detrusor pressure group,the normal detrusor pressure group and the increased detrusor pressure group.Meanwhile,normal urethral resistance group and the increased urethral resistance group were classified according to the urethral resistance status.The detrusor pressure at maximal flow rate (PdetQmax),the maximal flow rate (Qmax),the projected isovolumetric pressure (PIP),the voiding work,the voiding power and the voiding energy consumption were compared among the different groups.Results There were 56 cases,58 cases,18 cases in the decreased,normal and the increased detrusor pressure group respectively.The voiding work were (1.1 ± 0.5)J,(1.7± 0.7)J,(2.1±1.2)J; the voiding power were (15.3±7.3)mW,(31.9±12.6)mW,(42.5±21.1)mW; and the voiding energy consumption were (3.9± 1.2) J/L,(5.2± 1.9) J/L,(6.2±3.2) J/L in those three groups,respectively.With the increasing of detrusor pressure,PdetQ Q PIP,the voiding work,the voiding power and the voiding energy consumption all increased among three groups with significant difference (P＜ 0.05).There were 51 cases,81 cases in the normal and the increased urethral resistance group.The voiding work were (1.5±0.7)J and (1.5±0.8)J;the voiding power were (32.3±13.2)mW and (22.6±16.3)mW and the voiding energy consumption were (3.8±0.7) J/L and (5.4±2.4) J/L in two groups.The increased urethral resistance group had higher PdetQmax and voiding energy consumption (P＜0.05) and lower Qmax and voiding power (P＜0.05) than those in the normal urethral resistance group.However,the differences of PIP (P =0.438) and the voiding work (P =0.546) between the two groups were not determined.Conclusions The detrusor power curve method can be used to calculate the work parameters of voiding.This method can be applied to evaluate the compensatory state of bladder and is conductive to urodynamic analysis in low detrusor pressure status.Both detrusor pressure and urethral resistance had significant impact on the work capacity of bladder.

Objective To explore the application value of single-door laminoplasty via Y type nano-bone plate in treating multilevel cervical spondylotic myelopathy (MCSM) and analyze the short-term efficacy.Methods From January 2013 to December 2016,79 cases of MCSM were treated with single-door laminoplasty via Y type nano-bone plate to evaluate the improvement of post-operative neurological function by the Japanese Orthopaedic Association (JOA) evaluation system.We also measured cervical curvature of cervical X-ray and C5 sagittal diameter of the spinal canal before operation and 6 months after operation to understand the maintenance and enlargement of the spinal canal.The improvement degree of spinal cord compression was evaluated by preoperative and postoperative cervical MRI.Osseous healing on the open door side and the door shaft side was observed with the aid of three-dimensional spiral CT.Results Follow-up ranged from 6 to 36 months,with an average of (20.4±7.9)months.Preoperative JOA score was (8.6 ± 1.3) points and JOA score 6 months after operation was (14.3 ± 1.5)points (P ＜ 0.05).JOA improvement rate was (68.6 ± 15.8)％;postoperative follow-up X-ray and threedimensional spiral CT showed that the spinal canal had satisfying enlargement,the door shaft side all had osseous healing,the open door side osseous healing was not obvious,and there was no lamina collapse or reclosing.Sagittal diameter of theC spinal canal was (8.9±l.1)mm before operation and (15.1±l.1)mm 6 months after operation (P＜0.05).The spinal canal enlargement rate was (70.8±22.3)％,cervical curvature was (14.8± 7.0)°preoperatively and (15.1±6.7)°postoperatively with no significant difference (P＞0.05).Conclusion EOLP via Y type nano-bone plate is safe and efficacious in treating MCSM.It not only provides a good immediate fixation,but also provides the possibility for the open door side lateral osseous fusion.

Objective To evaluate the potential risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City,so as to provide evidences for establishing a post?transmission surveillance system for schistosomiasis in marsh?land regions. Methods The water infectivity,floating boatmen and fishermen infection,reservoir host infection and wild feces contamination were investigated in five districts/counties along the Yangtze River in Yangzhou City,including Guangling,Hanji?ang,Jiangdu,Yizheng and Development Zone,and the transmission factors and risky characteristics were assessed after inter?ruption of schistosomiasis transmission in marshland regions. Results A total of 15 key water regions were identified in the area along the Yangtze River in Yangzhou City in 2015. A total of 1 500 sentinel mice were placed,after breeding,their overall sur?vival rate was 99.33%;1 490 were dissected,with no schistosome infection. Of the 5 576 floating boatmen and fishermen exam?ined,no schistosome infection was observed,and among the 3 566 domestic animals(including 171 cattle,1 895 sheep and 1 500 pigs),no infections were detected. During the period between January and March,2016,there were 3 200 mouse traps placed on 8 marshlands,and 62 wild mice were captured from 6 marshlands,with a capture rate of 1.94%,and no schistosome?infected wild mice were seen. In addition,there were 35 pieces of fresh wild feces captured from 7 marshlands,including 11 pieces of bovine feces(31.43%),17 pieces of sheep feces(48.57%),2 pieces of dog feces(5.71%)and 5 pieces of other feces (14.29%),and no infections were detected. Conclusions There is a low risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City. However,the contamination of feces from bovine and sheep that are freely pastured on marshlands is a big threat to schistosomiasis control.

In recent years, there has been significant progress in the research of oncolytic viruses for the therapy of gliomas. The latest clinical trial results related to the modification, effectiveness, and safety of oncolytic viruses have brought hope for the development of glioblastoma treatments. Modified oncolytic viruses, particularly those based on the herpes simplex virus, have gained approval in Japan. Clinical trials involving recombinant poliovirus have shown better-than-expected survival outcomes with a strong safety profile. Notably, the first-time report of adenovirus in combination with immune checkpoint inhibitors for glioblastoma has demonstrated promising survival benefits and safety. However, challenges remain, including the selection of administration routes and the sustainability of treatment effects during oncolytic virus therapy. Therefore, further preclinical and clinical studies are required to improve the effectiveness and optimize treatment strategy for glioblastoma using oncolytic viruses.
