Objective To investigate the impact of cerebral microbleeds (CMBs) on cognitive function in ischemic stroke patients.Methods A total of 268 acute ischemic stroke patients recruited in the Ningbo First Hospital from January 2014 to June 2015 were divided into CMBs group (199 patients) and non-CMBs group (69 patients) according to whether complicated with CMBs by susceptibility-weighted imaging (SWI).According to the microbleed number, CMBs group patients were divided into 2 grades: grade 1 (1-5 CMBs) and grade 2 (≥6 CMBs). Montreal Cognitive Assessment (MoCA) was used to evaluate and compare the global cognitive function and cognitive domains of the patients. Results The total MoCA score and the scores of visuospatial/executive, attention domains in CMBs group were 20.95±4.53, 2.53±1.09, 3.83±0.97, while those in non-CMBs group were 26.82±1.25, 3.16±1.24 and 4.91±0.84. The total MoCA score and the scores of visuospatial/executive, attention domains were significantly lower in CMBs group than those in non-CMBs group (t=16.59, P<0.01;t=3.75, P<0.01;t=8.83, P<0.01). The total MoCA score and the score of attention domain in grade 1 CMBs group were 21.53±4.61 and 4.11±0.91 , which were significantly lower than those in non-CMBs group (t=14.09, P<0.01;t=14.23, P<0.01). Whereas the total MoCA score and the scores of visuospatial/executive, attention, orientation domains in grade 1 CMBs group were 21.53±4.61, 2.88±1.06, 4.11±0.91, 4.96±0.40, which were significantly higher than those in grade 2 CMBs group (18.58±3.08, 2.23±0.95, 3.63±1.01, 3.85±0.39, respectively;t=2.85, P<0.01;t=2.54, P<0.05;t=5.63, P<0.01;t=2.58, P<0.01). Multivariate regression analysis showed that independent risk factors of MoCA scores in ischemic stroke patients included CMBs (OR=3.15, 95% CI 1.28-5.12, P=0.005) and the number of CMBs (OR=1.73,95% CI 1.08-2.32,P=0.031). Conclusions CMBs and the number of CMBs were independently associated with cognitive impairment in ischemic stroke patients. And with the increasing of the microbleed number, the impairments of certain cognitive domains were more obviously.

Objective To evaluate the video-assisted thoracoscopic surgery(VATS) in the diagnosis and treatment of open thoracic traumas. Methods From July 2003 to July 2008,video-assisted thoracoscopic surgeries,including thoracic exploration,repair of the pulmonary laceration,parietal pericardium and diaphragm,hemostasis,evacuation of the clotted hemothorax,and mini-incision thoracotomy,were carried out in 64 selected patients with open thoracic traumas. Results Via VATS,all the 64 patients were diagnosed accurately: pulmonary laceration in 43(56 lesions),pericardiac rupture in 7(one of them showed right ventricular rupture),diaphragmatic rupture in 9(5 of them were complicated with spleen rupture,1 with hepatic rupture,and 1 with gastric rupture perforation),single intercostal vessel injury in 5,and combined intercoastal vessel injury in 3.The procedures involved VATS pulmonary laceration repair in 24(combined with thoracic wall hemostasis in 2),VATS combined mini-incision thoracotomy pulmonary laceration repair with Endo-GIA in 11(silk suture was employed in 6,and pulmonary wedge resection in 2).Through VATS procedure,hemostasis and repair were completed for pericardiac repair in 3,and diaphragmatic repair in 5.Thirteen cases were converted to open thoracic surgery.The duration of VATS procedure ranged from 32 to 124 minutes with a mean of 65.8 minutes.After the procedure,6 patients developed pneumothorax,4 showed mild subcutaneous emphysema,and 9 had slight hemoptysis in 1 to 12 days after the treatment.The patients were followed up for 2 to 60 months(mean,28.5 months).Chest X-ray performed during the period showed no pleural effusion,pneumothorax or other trauma-related complications.Conclusion VATS is effective for the diagnosis and treatment of open thoracic traumas with less surgical injuries and good outcomes.

Objective To investigate the significance of an accessory hepatic vein (AHV) in the interventional treatment of Budd-Chiari syndrome (BCS).Methods From Mar.2011 to Jun.2013,35 patients with BCS who also had an AHV were included into this study.The patients were divided into two groups according to whether the AHV was obstructive:21 patients had obstruction to the inferior vena cava (IVC) and to the 3 hepatic veins (HV),but the AHV was open; 14 patients had obstruction to the AHV and the 3 HVs.In 13 of these patients the IVC was open,but 1 patient had obstruction to the IVC.During treatment,the patients in the AHV open group underwent balloon dilation or stent insertion of IVC ; patients in the AHV obstruction group underwent balloon dilation or stent insertion of AHV.The patient with obstruction to the IVC underwent balloon dilation of IVC first.Results All patients were successfully treated without any procedure-related complications.In the AHV open group,the average pressure of the AHV decreased from (28.81 ± 6.23) cmH2 O (1 cmH2O =0.098 kPa) before treatment to (18.62 ± 5.06) cmH2O after treatment (P ＜ 0.01) ; the average serum TBIL decreased from (23.24 ± 6.41) μmol/L before treatment to (19.52 ± 4.31) μmol/L after treatment (P ＜ 0.01) ; the average serum albumin changed from (33.76 ± 3.74) g/L before treatment to (34.05 ± 3.62) g/L after treatment (P =0.485).In the AHV obstruction group,the average pressure of the AHV decreased from (36.29 ± 11.65) cmH2O before treatment to (22.07 ± 7.67) cmH2O after treatment (P ＜ 0.01) ; the average serum TBIL decreased from (31.24 ± 9.54) μmol/L before treatment to (20.93 ±7.26) μmol/L after treatment (P ＜0.01) ; the average serum albumin changed from (32.14 ± 4.55) g/L before treatment to (32.11 ± 4.47) g/L after treatment (P =0.861).During follow-up,no patients experienced recurrence of symptoms in the AHV open group; one patient experienced recurrence of symptoms 5 months after treatment in the AHV obstruction group.This patient received a second balloon dilation of the AHV.Conclusions For patients with BCS with IVC and the 3 HVs obstruction,if the AHV was open,we could only treat the IVC.For patients with BCS with AHV and the 3 HVs obstruction,AHV dilation followed by recanalization of AHV was also effective.

This study was aimed to analyze the living status and medication rules of traditional Chinese medicine (TCM) treatment of postoperative patients with stage II and III colorectal cancer by Prof. Y ang Y ufei. A total of 70 postoperative patients with stage II and III colorectal cancer were enrolled in the cohort study at the Xiyuan Hospital from September 2007 to August 2009. The out-patient records were reviewed and follow-ups were given for the analysis. The results showed that until July 2013, the loss to follow-up rate was 8.6%, which was less than 15%. The four-year postoperative recurrence and metastasis rates of the high and low exposure group were 7.1% and 25.0%, respectively. The Fisher exact probability test showed that the high exposure and long period therapy of TCM treatment can significantly reduce the recurrence and metastasis rate of patients (P < 0.05). The analysis of Prof. Y ang Y ufei's medication rules in TCM treatment of postoperative colorectal cancer showed that the syndrome differ-entiation pattern with the highest frequency was spleen-stomach deficiency pattern; and the liver-kidney yin defi-ciency pattern was in the second place. The prescriptions used with the highest frequency were Si-Jun-Zi Decoction and Liu-Wei-Di-Huang Decoction. It was concluded that the comprehensive TCM treatment can improve the prog-nosis of stage II and III colorectal cancer. The treatment also has certain meaning in the reducing of the recurrence and metastasis rate of patients, and prolonging the time of the recurrence and metastasis.

Objective To evaluate the effect of exogenous wild PTEN gene stable transfected into human ovarian cancer cell line HO-8910 on phosphatidyl inositol 3-kinase( PI3K)/protein kinase B (Akt)siganal pathway and cells proliferation. Methods Wild-type PTEN recombinant eukaryotic expression plasmid was constructed and then was transfected into HO-8910 cells by lipofectamine 2000. The expression of PTEN, Akt1, Akt2, PI3K mRNA and protein of PTEN were tested by reverse transcription( RT)-PCR and Western blot. The proliferation of HO-8910 after wild PTEN gene transfected was measured by methyl thiazolyl tetrazolium(MTT). Results Wild-type PTEN gene was successfully transfected into HO-8910 cells. The results of RT-PCR and western bolt showed that there were the significant expression high level of PTEN mRNA and protein after infected by wild-PTEN plasmid than those in the control[ ( 17 372 ±23)vs.(39±1 )vs. (78 ±4)copies/ml,P ＜0. 05 ]. While the expression of mRNA of Akt1, Akt2 and PI3K were decreased clearly than those in the control [ (28 ± 2 ) vs. ( 115 ± 5 ), (7 ± 1 ) vs. ( 18 ± 2), (61 ± 2 ) vs.(84 ± 2)copies/ml , all P ＜ 0. 05 ]. The proliferation rate of HO-8910 cells was obviously slower than those in the control (90 158 ±47 vs. 148 251 ±65 vs. 250 115 ±62, P＜0.05). Conclusion Transfection of PTEN may increase the expression of PTEN and inhibit the proliferation of HO-8910 cells, in which PI3K/ Akt siganal pathway is inhibit significantly.

Abstract Deviant behaviors among adolescents is widespread and have substantial impacts on family and society. Increasing evidence has shown that adolescents who experienced traumatic stress events and suffered from post traumatic stress disorder are at significantly higher risk of deviant behaviors than their healthy peers and have their personal lives negatively affected. In this review, the effect of PTSD on deviant behaviors in adolescents is summarized, in which adolescent deviant behaviors are mainly classified into extroverted, introverted, and academic deviant behavior, as well as deviant habits. Meanwhile, aims to explore the neural mechanism linking PTSD and adolescent deviant behaviors, and to provide suggestions for intervention of deviant behaviors.

Objective To evaluate the effectiveness of low-dose erythromycin for the treatment of feeding intolerance in preterm infants in China.Methods In this study,random clinical trials on the treatment of feeding intolerance in preterm infants with intravenous low-dose erythromycin published were searched at Chinese Journal Full-text Database,Chongqing Weipu Database and Wanfang database by using the methods of Cochrane systematic review.At the same time the information from related journals,professional data and network were hand-searched.The publishing deadline for the literatures reviewed in this study was August 2012.Statistical analysis of clinical data was performed by using RevMan 4.2 software provided by the Cochrane Collaboration.Results A total of 9 studies were included.The results showed that compared with the group of comprehensive therapy,the group of low-dose erythromycin was superior in the following aspects with significant differences(P ＜ 0.05):the average length of hospital stay,time of parenteral nutrition,time to full feeding,the incidence rate of feeding intolerance (Z =3.44,P =0.000 6 ; Z =6.78,P ＜0.000 01 ; Z =3.96,P ＜ 0.000 1 ; Z =2.51,P =0.01).Conclusion Low-dose erythromycin therapy for feeding intolerance in preterm infants is superior to the comprehensive therapy.It provides a prospective therapeutic method for feeding intolerance in preterm infants.However,large scale,multicenter and well-designed clinical trials should be adopted to confirm the conclusions.
