ObjectiveTo study the effect of hyperbaric oxygenation (HBO) treatment on post-stoke depression (PSD) and neurological functional rehabilitation.Methods60 patients with PSD were randomly divided into two groups, treatment group and control group. Patients in the treatment group were given HBO treatment in addition to the regular treatment. Changes of scores of Hamilton depression (HAMD), Chinese stroke scale (CSS), and activity of daily living (ADL) before and after treatment in two groups were observed and evaluated.ResultsAfter 1 month treatment scores of HAMD, CSS, and ADL in the treatment group got obviously better results than before treatment (P<0.01). While scores in the control group had no significant difference(P>0.05).Conclusions It is suggested that HBO may improve the depressive symptom and neurological functional rehabilitation in PSD patients.

Objective To evaluate the efficacy and safety of combined intrapleural therapy with bevacizumab and cisplatin in controlling malignant pleural effusion(MPE)caused by non?small cell lung cancer(NSCLC). Methods A total of 63 NSCLC study subjects with MPE were randomly assigned to one of two groups(A and B). Group A(bevacizumab,n=32)received intrapleural bevacizumab(5 mg/kg)with cisplatin(40 mg/m2) therapy once a week for a total of three cycles. Group B(cisplatin,n=31)received intrapleural cisplatin therapy alone with the same dose and cycle. Pleural fluid was collected from both groups prior to and after treatment. The levels of VEGF in the pleural fluid were determined by ELISA. The cura?tive effect and adverse reaction were observed and follow?up was conducted. Results In 63 evaluable study subjects,the curative efficacy in the be?vacizumab group was significantly higher than that found in the cisplatin group(84.3%vs 61.3%,respectively,P<0.05). But the overall survival (OS)of the two groups showed no statistically significant difference(13.0 months vs 12.0 months,P>0.05). After treatment,The VEGF levels in the MPE were significantly decreased in both groups. In the bevacizumab group,the levels of VEGF in the pleural fluid were significantly lower com?pared to those of the cisplatin group after treatment,showing greater efficacy(P<0.05). The VEGF levels of the two groups whose treatment was in?valid had no statistically significant difference(P=0.079). There was no significant difference in gradeⅢ/Ⅳadverse events between the two groups. All procedures were well tolerated by the patients. Conclusion Combined intrapleural therapy with bevacizumab and cisplatin was effective and safe in managing NSCLC?mediated MPE. The patients showed high tolerance to the therapy. For prediction of local treatment efficacy of bevaci?zumab using the VEGF expression levels in MPE,further research was needed.

[Objective]To study the therapeutic effect of recombinant erythropoietin for contusion injury of spinal cord.[Method]Contusion injury of spinal cord was caused by weight dropping in 24 New Zealand rabbits.Twelve hours after injury,the rabbits in control group were given natural saline intravenously and rabbits in low,mediate and large-dose group were given rh-EPO 100 IU/kg,500 IU/kg and 1000 IU/kg respectively.Neurological status of lower limbs were scored at 24 hours,48 hours and one week after spinal cord injury.All rabbits were killed one week after injury and spinal cords were stained by HE and caspase-3 method.Electronic microscopy was used to evaluate ultrastructural injury.[Result]The neurological scores of EPO treated groups were significantly higher than that of control group.HE and Caspase-3 immunohistochemistry showed that histological and ultrastructural damage of EPO treated groups were less severe than that of control group.The caspase-3 positive neurons were significantly fewer than that of saline treated group.There was no significant difference of therapeutic effect between mediate and large-dose EPO treated groups.[Conclusion]Rh-EPO administered 12 hours after contusion injury of spinal cord could lessen histological and ultrastructural damage,prevent apoptosis of neurons and promote neurological recovery of spinal cord.Mediate dose of rh-EPO is the appropriate treatment choice for spinal cord injury.

Objective To investigate the clinical efficacy of three-dimensional (3D) and two-dimensional (2D) laparoscopic surgeries in the treatment of Todani type Ⅰ choledochal cyst.Methods The retrospective cohort study was conducted.The clinical data of 59 patients with Todani type Ⅰ choledochal cyst who were admitted to the People's Hospital of Hunan Province between January 2013 and January 2016 were collected.Thirty patients undergoing 2D laparoscopic surgery between January 2013 and June 2014 were allocated into the 2D group and 29 patients undergoing 3D laparoscopic surgery between July 2014 and January 2016 were allocated into the 3D group.There were the same Trocar placement and surgical procedure in the 2 groups,and surgical procedure completely followed the treatment principle of Todani type Ⅰ choledochal cyst.Observation indicators included (Ⅰ) surgical situations:conversion to open surgery,operation time,volume of intraoperative blood loss,(2) postoperative situations:postoperative complications,(3) follow-up.Patients were followed up by outpatient examination or telephone interview to detect postoperative recovery up to April 30,2016.Measurement data with skewed distribution were presented as M (range) and analyzed using the Mann-Whitney U test.Count data were compared by Fisher exact probability.Results (1) Surgical situations:patients in the 2 groups underwent laparoscopic choledochal cystectomy + Roux-en-Y hepaticojejunostomy.Two patients in the 2D group received conversion to open surgery and patients in the 3D group received the successful surgery without conversion to open surgery.Rate of conversion to open surgery in the 2D and 3D groups were 6.7％ (2/30) and 0,respectively,with no statistically significant difference (P ＞ 0.05).Operation time in the 2D and 3D groups were 285 minutes (range,240-390 minutes) and 190 minutes (range,140-215 minutes),with a statistically significant difference (U =40.0,P ＜ 0.05).Volume of intraoperative blood loss in the 2D and 3D groups were 50 mL (range,10-300mL) and 45 mL (range,20-250 mL),with no statistically significant difference (U =1 018.5,P ＞ 0.05).(2)Postoperative situations:patients in the 2 groups had good recovery,without occurrence of severe complications in Clavien-Dindo≥ Ⅲ stage.Four and 1 patients in the 2D and 3D groups were complicated with bile leakage (in Ⅱ stage of Clavien-Dindo) and 1 and 1 were complicated with upper gastrointestinal hemorrhage (in]][stage of Clavien-Dindo),respectively,with no statistically significant difference (P ＞ 0.05).Overall incidence of complications in the 2D and 3D groups were 16.7％ (5/30) and 10.3％ (3/29),with no statistically significant difference (P ＞ 0.05).All the patients were cured by conservative treatment.(3) Follow-up:59 patients were followed up for 5-36 months,with good recovery and without occurrence of reflux cholangitis,hepatic and intestinal anastomosis stenosis and reoperation.Conclusions 3D and 2D laparoscopic surgeries are safe and effective for Todani type Ⅰ choledochal cyst.Compared with 2D laparoscopic surgery,3D laparoscopic surgery can reduce the operation time and not increase the complications,and it should be discreetly promoted based on the experiences of surgeons.

Objective To investigate the effect of up-regulation of tetraspanin-5 (Tspan-5) expression on the metastatic ability of colorectal cancer (CRC) cells. Methods The coding sequence of Tspan-5 mRNA was amplified from total RNA of LoVo cells by RT-PCR and cloned into pEGFP-C1 to construct Tspan-5/pEGFP-C1,a eukaryotic expression vector. The expression of Tspan-5 in LST-R1 cells was up-regulated by gene tranfection. Western blotting was used to detect the expression level of Tspan-5/EGFP fusion protein,and laser scanning confocal microscopy (LSCM) was used to observe the distribution of Tspan-5/EGFP in LST-R1 cells. The changes in adhesion,migration and invasion ability of LST-R1 cells were determined by adhesion,migration and invasion experiment in vitro,respectively. Liver metastasis model of nude mice was used to test the changes in liver metastasis ability of LST-R1 cells in vivo. Results The Tspan-5/EGFP fusion protein could be detected by Western blotting in Tspan-5/pEGFP-C1 transfectants. LSCM showed that Tspan-5/EGFP protein located in cell membrane. Adhesion and migration assays showed that up-regulation of Tspan-5 expression level significantly promoted the adhesion and migration ability of LST-R1 cells on a series of extracellular matrix (ECM) components,including collagen IV,FN,LN and VN (P

According to the theory of in vitro radioassay, using TSHAb as binder and 125I-staphylococcal protein A (125I-SPA) as tracer agent, a new method for detecting the abnormal immunoglobulin (aIgG) in the sera of patients with Graves disease (GD) was reported. In the initial study of the method, the most appropriate interacting conditions of TSHAb with aIgG were explored and compared with ELISA using ganglioside (GLS) as a binder. The relationship between aIgG and thyroid-stimulating imunoglobulin(TSI) was probed into. The results showed that TSHAb could interact specifically with aIgG in vitro; but it could not interact with IgG from sera of normal subjects, systemic lupus erythematosis (SLE) patients and diabetic patients. With aIgG as an evaluating index, the mean value in 29 normal subjects was 1. 06?0. 17. When the sera of 72 patients with GD in different clinical stages were studied, the aIgG index was positive in 83% of untreated GD patients (n = 24), in 12% of GD patients in clinical remission (n = 25) and in 82% of relapsed GD patients (n = 23). Very significant difference was observed between normal subjets and untreated and relapsed patients with GD (P
