Objective To evaluate the safety and effect of extraperitoneal laparoscopic radical prostatectomy for high-risk prostate cancer. Methods From January 2012 to August 2015, 49 patients diagnosed high-risk prostate cancer underwent extraperitoneal laparoscopic radical prostatectomy with 'sandwich' urethra reconstruction. Results None converted to open surgery and the mean operative time was (2.15 ±0.29) h, mean intraoperative blood loss was (60.25 ± 20.29) ml. No rectal injury was observed. The patients were ambulant 1 to 2 days postoperatively. Pelvic lymph nodes metastasis was found in 5 cases. Positive margin was found in 13 cases. Mild urinary incontinence oc-curred in 3 cases. Urethral stenosis occurred in 2 cases. Biochemical relapses occurred on 5 cases during the follow-ing period of 1~43 months for 46 cases. Conclusions Extraperitoneal laparoscopic radical prostatectomy is safe and effective in treatment of high-risk prostate cancer. The very key is to master the anatomy of prostate and laparoscop-ic techniques.

Radiation therapy is one of the main therapeutic means of thoracic malignant tumors .When re-ceived certain radiation ,lung may cause the common complication of chest tumor radiotherapy -Radiation -in-duced Lung Injury ( RILI) ,which restricts the radiation dose for the tumor region and may affect patient outcomes . RILI is closely associated with multiple cytokines ,such as interleukin family,tumor necrosis factor,transforming growth factor,etc.Currently,research on RILI control methods has also made some breakthrough ,this article elab-orates on this individually .

Glioma is the most common malignant brain tumor with high malignancy and lethality.The specific potential radiolabeled nanoparticles have been applied in the glioma research for non-invasive,dynamic,real-time and quantitative evaluation.Furthermore,radiolabeled nanoparticles have shown great potential in targeted therapy of glioma.The up-to-date application of radiolabeled nanoparticles in SPECT imaging,PET imaging,multimodality imaging and theranostics in glioma are reviewed in this article.

Acute pancreatitis(AP) is mainly caused by gallstone disease and excessive alcohol consumption.Overall, about one fifth of patients develop into severe acute pancreatitis( SAP), which is still associated with a mortality rate exceeding 30%. This type of AP is usually accompanied by necrosis of the pancreas and/or organ failure. Treatment of SAP in several aspects, such as the application of antibiotics, nutritional support, surgical time, the method of operation, are still in dispute. In recent years, minimally invasive technique is increasingly used in the treatment of SAP, and some patients may benefit from the adoption of minimally invasive surgery.This article aims to review the current progress on the treatment of SAP.

Objective To investigate reconstructive repair methods of a large scalp defect with the granulation tissue wounds and skull exposure caused by the trauma.Methods Skin and soft tissue expansion technique was used to repair eight patients with a large scalp defect with the granulation tissue wounds and skull exposure caused by the trauma.The skin and soft tissue expanders were embedded under normal epicranial aponeurosis after the formation of fresh granulation tissue wound.Strict aseptic technique as well as water injection was done in the expansion process and moderate expansion to maintain rich blood circulation in the expansive parts.Results 12 skin and soft tissue expanders were implanted in 8 patients and the scalp wounds were completely repaired.No infection was detected after surgery and injection expansion process.Conclusions The skin and soft tissue expansion can be used to reconstruct post-traumatic scalp defect with granulation tissue wound and skull exposure.

Objective To investigate the anti-mutation of Chinese medicinal herb Herba Leonuri and its effect on T lymphocyte proliferation in spleen.Methods The micronucleus test of mouse bone marrow cell(MNT) :thirty mice were divided into six groups(n= 5),negative control(NS),cyclophosphamide group(CP 3.0 mg?kg-1),Herba Leonuri antimutagenesis groups(Herba Leonuri with dosages of 1.0,2.0,4.0,8.0 g?kg-1+CP30 mg?kg-1).The improved method was used to detect the micronuclei frequency.Lymphocyte transformation test:twenty-four mice were divided into four groups(n=6),saline control,CP control(30 mg?kg-1),Herba Leonuri(2.0 g?kg-1),Herba Leonuri +CP(2.0 g?kg-1 Herba Leonuri +CP 30 mg?kg-1).MTT assay was used to calculate the stimulation index(SI).Results The micronuclei frequencies in Herba Leonur 2.0,4.0,8.0 g?kg-1 groups were lower than that in CP group(P

Objective To evaluate the therapeutic efficacy of transcather arterial chemoembolization for hepatic carcinoma and its influence on hepatic function. Methods Patients with HCC were divided into three groups according to repeated TACE times. The therapeutic efficacy was assessed with survival rate, car-cionma size and biologic response (AFP). Hepatic function was evaluated according to some hepatic param-eters(ALT,AST,ALB,DB,TB,PT). Results All three groups responses rates were 4.3%, 23.1% and 31.6% ;srespectively,liver function in group 1 and group 2 returned to its pretreatment level(P <0.05) ,but in group 3, liver function did not return to its pretreatment level associated with more repeated TACE times. The 1-,2-and 3-year survival rates of group 1 were 27.0%, 10.8%, 5.4% ; respectively, while those of group 2 were 57.1%, 33.3%, 19.0% ; respectively, which were not significantly different from those of Team 3 ,which was 62.5%, 37.5%, 18.8%, respectively. Conclusions (1) three to four repeated times TACE was an effective palliative treatment that prolongs survival of patients with HCC,while 1 to 2 re-peated times had a limited benefit; (2) Irreversible hepatic impairment induced by TAEC could affect its therapeutic efficacy.

Objective To investigate the treatment options of acute biliary pancreatitis.Methods A retrospective review was performed in 134 consecutive patients who presented to a single tertiary care institution from 2000 to 2010 with acute biliary pancreatitis.Results Of the 134 patients,30 had a persistent (commonbile duct,CBD)stone.Following multivariate analysis,at admission CBD size on ultrasound,alkaline phosphatase(ALP),total bilirubin(TB),significantly correlated with persistent CBD stone.Receiver operator curve analysis and linear regression were applied to obtain optimal and equitable predictive values,and variables combined.Optimal values were.,CBD≥10 mm;AP≥150 U/L;and TB≥51.3μmol/L.Presence of three variables had an associated odds ratio(OR)of29.5(P<0.001)for presence of persistent CBD stone.Zero variables conferred asignificantly decreased probability of CBD stone,OR 0.07(P<0.001).Conclusions Presence of three variables significantly correlated with persistent CBD stone.Biliary evaluation by endoscopic retrograde cholangiopancreatography(ERCP)is suggested.In the absence of any positive predictive variables,cholecystectomy may be sufficient.Decisions regarding patients with one to two be made vailables should occur on a case-to-case basis.

BackgroundIt has been well-known that integrin linked kinase(ILK) plays an important role in the pathogenesis of neorascularization.But there are few researches to elucidate the relationship between ILK and retinal nevascularization. Objective This study was to explore the expression and significance of ILK on retinal neovascularization and new vessels regression in the oxygen-induced retinopathy(OIR) mouse model. Methods One hundred and twenty-eight 7-day-old C57BL/6J mice were randomly divided into the normal group and model group.The mice were rose in(75±2)％O2 environment with mother mice together for 5 days and then in normal environment for 5 days to establish the OIR models.The mice in normal group were rose in the normal environment for 21 days.The 17-day-old mice were sacrificed and retinal sections were prepared for histopathological examination and the numbers of the cellular nuclei of vascular endotheliumbreaking retinalinternal limiting membranewere calculated.Retinal sections and sheeting were prepared in 12,14,17 and 21 -day-old mice to examine the formation and regression of new blood vessel using ADP histochemistry staining,and then immunochemistry,real-time PCR and Western-blotting were used to detect the expressions of ILK and its mRNA in retina. ResultsThe numbers of the cellular nuclei of vascular endothelium breaking retinal internal limiting membrane were (45.64 ± 12.17 )in OIR group,and those of the normal group were( 0.35±0.14 )with a significant difference between two groups (t =22.85,P＜0.05).Retinal new blood vessel appeared in 14-day mice,and peaked in 17-day mice and then regression in 21-day mice.ILK protein was expressed mainly in retinal ganglion cell layer,inner nuclear layer,inner plexiform layer and photoreceptor layer.Real-time PCR showed that ILK mRNA expressing levels in retina in model group were( 1.00±0.22),(1.85±0.17),(1.58±0.43) and(1.53±0.36) respectively in 12-,14-,17- and 21-day mice.Westernblotting determined that the A value of the ILK/β-actin was increased in 12-,14-,17-day mice and decreased in 21-day mice,and the A values were significantly higher in model group than the control group in various aged mice ( t =2.97,P＜0.05 ;t =11.88,P＜0.01 ;t =16.84,P＜0.01 ;t =13.00,P＜0.01 ). ConclusionsThese results indicate a space-time corresponding relation between the expression of ILK and retinal neovascularization.The obvious positive expression of ILK may be highly correlated with retinal neovascularization.
