Objective To explore the effect of a multimodal electroencephalogram ( EEG) data visualiza-tion system on the motor imagery ability of stroke survivors. Methods Twenty stroke patients were randomly di-vided into an experimental group and a control group, each of 10. Both groups were provided with brain-computer interface-based motor imagery ( MI) training. At the same time, the experimental group was monitored and guided using an online, multimodal EEG data visualization system developed in our department. The classification accuracy ( CA) and event-related desynchronization ( ERD) of the 2 groups′ motor imagery were compared before and after the treatment. Results Before the treatment, no significant differences in the average CA of MI were found be-tween the experiment group (50.92±2.08) and the control group (49.35±4.20)(P>0.05). After the treatment, however, the experimental group′s average CA had increased to (64.52±5.27), significantly higher than that of the control group (51.18±5.02). When the stroke patients imaged affected upper extremity movements, obvious ERD was observed in the α frequency around the bilateral central motor regions of both groups, especially in the experi-mental group, but without significant differences between the two groups. However, no significant changes were found in the ERD of theβwaves of the two groups( P>0.05) . Conclusion The proposed online multimodal elec-troencephalogram data visualization system can help stroke patients imagine movements actively. It is worth sprea-ding in clinical practice.

Objective To investite the effect of endotoxin pretreatment on lung injury induced by hepatic ischemia reperfusion in rabbits and its mechanism. Method Forty-eight New Zealand white rabbits were randomly divided into4 groups with 12 rabbits each group:routine control group,pretreatment control group,ischemia reperfusion group (IR group), and preperfusion group( LPS + IR group). Rabbits of routine control group received operative dissector only, and those of pretreatment control group received pretratment of daily intraabdominal injection of lipopo|ysaccharide(O.5,0.5,and 1.0 mg/kg,respectively)in the 3 days before operative dissector.Livers of IR group were rendered and ischeraic for 30 minutes, and repeffused for up to 4 hours. Rabbits of LPS +IR group received the preueaunent before heretic ischemia repeffusion. Four hours after reperfusion, serum endotoxin,tumor necrosis factor-α(TNF-α), wet/dry ratio and broncho-alveolar lavage fluid protein content of lung,malondialdehyde(MDA) and mpenrxide dismutase(SOD) in lung homogenate, lung injury ratio, and activity of Nuclear factor-kB(NF-kB) in alveolar macrophage wene examined. Differences within the groups were analyzed using One way ANOVA. Results Between the two control groups,there were no significant differences in all indexes(P>0.05). The TNF-α[ (48.31±5.31)pg/ml vs.(56.47±5.09)pg/ml, P<0.01],wet/dry ratio [(4.98±0.33)vs. (5.22±0.31), P = 0.03],broncho-alveolar hvage fluid protein content[(0.68±0.11)g/L vs. (0.76±0.10)g/L, P =0.04],MDA[(0.86±0.06)nmol/mg vs. (0.93±0.07)nmol/mg, P =0.02],lung injury ra-tio[(13.4±4.3)% vs. (17.4±4.1)%, P = 0.03],and the activity of NF-gB[(5.82±1.12)OD/mm2 vs.(7.40±1.26)OD/mm2, P<0.01] in alveolar macrophage of the LPS+ IB group were all significantly lower than those of IB group, while the SOD[ (90.30±7.38 )U/rag vs. (84.44±7.90 )U/rag, P = 0.04]of LPS + IR group was significantly higher than that of IR group. Conclusions Endotoxin pretrealment may ameliorate the lung injury induced by hepatic isehernia reperfusion. The mechanism may be that endotoxin pretreatment deoreases production of serum TNF-α and the activity of NF-kB in alveolar maerophage.

Objective To indentify the gene mutation of fibroblast growth factor receptor 3 (FGFR3) gene in a Chinese family with congenital achondroplasia (ACH). Methods The genomic DNA from 2 clinically diagnosed ACH patients and the other 4 members from the same family was prepared for PCR. The products of PCR were purified and then sequenced directly. Results Two patients with ACH in this family showed G-A transition mutation at nucleotide 1138 as heterozygotes. Conclusion The G-A transition mutation at nucleotide 1138 in transmembrane domain of FGFR3 gene seems to be the pathologic cause of this Chinese family with ACH.

Objective:To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC.Methods:A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People′s Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B).Results:Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA 125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage ( P=0.006) and residual lesion size ( P=0.020). Conclusions:OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.

BACKGROUND AND OBJECTIVEIt has been proven that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was a new minimally invasive method in the diagnosis for mediastinal lymph nodes. The aim of this study is to evaluate the diagnostic and staging yield of EBUS-TBNA for lung cancer.

METHODSSeventy-five patients with tumors and enlarged mediastinal lymph nodes found by CT underwent the diagnosis by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) from April 1, 2009 to Febuary 8, 2010. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated.

RESULTSSeventy-five patients with 177 lymph node groups (2.4 groups in average) were studied. Histopathological samples were found in 49.33% patients and in 28.81% groups. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA for diagnostic were 98.43%, 100.00%, 100.00%, 91.67% and 98.66%, respectively, in per patient analysis and were 95.10%, 100%, 100.00%, 82.93%, and 96.05%, respectively, in per group analysis, higher than CT examination (P < 0.05) expect for sensitivity (P = 0.435). Staging changed in 19 (26.03%) patients after EBUS-TBNA.

CONCLUSIONEBUS-TBNA proved to be a safe procedure with a high yield for the diagnosis of lung cancer.
