Methods The clinical data of 753 patients with obstructive jaundice treated with ultrasound-guided PTBD in our hospital from January 2001 to June 2008were retrospectively analyzed. Results The 753 patients received a total of 791 treatments of PTBD.The occurring rates of severe, common, and long-term complications were 1.14 % (9/791), 11.88 %(94/791 ) and 4.3% (9/791), respectively. Only 1 patient died of manipulation-related complications.Conclusion Ultrasound-guided PTBD is an effective method for treatment of obstructive jaundice.

Objective To investigate the effects of edaranvone on lung injury induced by myocardial ischemia-reperfusion (I/R) in rats. Methods Twenty-four male Wistar rats weighing 250-300 g were randomly assigned to one of 4 groups ( n = 6 each): group Ⅰ sham operation (group S); group Ⅱ myocardial I/R and group Ⅲ and Ⅳ different doses of edaravone ( group E1, E2 ). The animals were anesthetized, intubated and mechanically ventilated. In group Ⅱ-Ⅳ myocardial I/R was induced by occlusion of left anterior descending coronary artery for 45 min followed by 3 h reperfusion. In group Ⅲ and Ⅳ edavarone 3 and 10 mg/kg was administered via right femoral vein at 1 min before reperfusion respectively. The animals were sacrificed by exsanguination at the end of 3 h reperfusion. Blood was collected for determination of serum CK-MB activity and total protein content. The left lung was lavaged and the broncho-alveolar lavage fluid (BALF) was colleted for determination of protein content. Pulmonary permeability index (PPI) was calculated. The lung tissue was obtained for determination of BD-2 mRNA and protein and TNF-α expression. Results The serum CK-MB activity, PPI,BD-2 mRNA and protein and TNF-α expression were significantly higher in group I/R, E1 and E2 than in group S,but significantly lower in group E1 and E2 than in group I/R and in group E2 than in group E1. Conclusion Edaravone can reduce myocardial I/R-induced lung injury by scavenging oxygen free radicals and inhibiting inflammatory response of lung tissues in rats.

Background Benign lymphoepithelial lesion of lacrimal gland is not a common orbital disease in clinic,which mainly presented as symmetrical and painless enlargement of bilateral lacrimal glands.However,the etiology and pathogenesis of this disease is still unclear now.Objective This study was to screen the differentially expressed genes between benign lymphoid epithelial lesion of lacrimal gland and orbital cavernous hemangioma and explore the pathogenesis of benign lymphoepithelial lesion of lacrimal gland at the molecular level.Methods Nine patients diagnosed as benign lymphoepithelial lesion of lacrimal gland in Beijing Tongren Hospital,Capital Medical University were enrolled from September 2010 to April 2013,and nine patients with orbital cavernous hemangioma served as control group.The intraorbital tissue was collected during surgery.Whole-genome gene expression microarray was used to detect the expressed genes,and limma algorithm was used to analyze the differentially expressed genes between the benign lymphoepithelial lesion of lacrimal gland and the orbital cavernous hemangioma.Real-time PCR was used to verify differentially expressed genes,Fisher method and gene ontology (GO) functional analysis were performed to realize function and signaling pathways analysis.This study complied with Helsinki Declaration and the protocol was aproved by Institutional Review Board of Beijing Tongren Hospital,and informed consent was obtained.Results Total 5 260 differentially expressed genes were screened between benign lymphoepithelial lesion of lacrimal gland and orbital cavernous hemangioma.The Fisher function and signaling pathways analysis showed that 109 GO terms were significantly upregulated and 101 GO terms were significantly downregulated,and 32 relevant signaling pathways were significantly upregulated and 25 signaling pathways were significantly downregulated in the benign lymphoepithelial lesion of lacrimal gland.GO analysis showed that the expression enrichment of complement receptormediated signaling pathway was high,then following the upregulation of T cell and B cell signaling pathways and downregulation of mitogen-activated protein kinase (MAPK) and transforming growth factor-β (TGF-β) signaling pathways.Real-time PCR results showed that the expressions of TIPRL,TLR7 and TLR10 genes were significantly higher in the benign lymphoepithelial lesion of lacrimal gland than that in the orbital cavernous hemangioma,with significant differences between the two diseases (Z =-2.03,-2.32,-2.32;all at P＜0.05),which was consistent with the microarray data.Conclusions Gene expression profiles are significantly different between benign lymphoepithelial lesion of lacrimal gland and orbital cavernous hemangioma.Those differentially expressed genes play roles in the upregulation of T cell and B cell signaling pathways,downregulation of MAPK and TGF-β signaling pathways and the change of complement system.It is implied that a comprehensive effect of various genes and pathways participates in the pathogenesis of benign lymphoepithelial lesion of lacrimal gland.

Objective To observe the ultrasonographic features of primary female genital system lymphoma and its histopathological characteristics.Methods Sonographic appearances and histopathological characteristics of 14 patients who were pathologically comfirmed as primary female genital system lymphoma were reviewed.Results Fourteen patients underwent ultrasonography and 15 lesions were found,6 cases of which were found in the ovary and cervix separately,3 cases in the uterine body.Among the lesions detected,10 of which respectively represents extremely low echo and homogeneous internal echo,all lymphomas had posterior enhancement.The margins were most frequently circumcribed (13/15),5numbers primary lymphomas of the ovary were mostly elliptical in shape,while 5 numbers of cervix tumors showed the shape of lobular,all of the tumors in the uterine body showed diffuse symmetrical enlargement without disruption of the endometria.Color Doppler imaging showed hypervascularity in most tumors(13/15).The pathological examination showed that all tumors were non-Hodgkin lymphoma diffuse B-cell type.Conclusions Primary female genital system lymphoma has some ultrasonic features,including extremely low echo,homogeneous echo and posterior enhancement.Final diagnosis depends on the histopathology.

BACKGROUND:Mechanical signal has close correlation with the growth, development, repair and reconstruction of the skeletal system and the development of disease, the effect and the mechanism on bone marrow mesenchymal stem cel s is worthy to concern.
OBJECTIVE:To explore the effect and mechanism of hydrostatic pressures on the differentiation of bone marrow mesenchymal stem cel s.
METHODS:Short-term experiment:the human bone marrow mesenchymal stem cel s were incubated into the normal Dulbecco’s modified Eagle’s medium, osteogenic medium or the Dulbecco’s modified Eagle’s medium containing extracel ular signal-regulated kinase 1/2 inhibitor U0126, respectively. Homemade pressure loading system was used to impose 0, 40 and 80 kPa hydrostatic pressure for 1 and 4 hours. Long-term experiment:human bone marrow mesenchymal stem cel s were incubated into the normal Dulbecco’s modified Eagle’s medium or osteogenic medium respectively, and then 40 kPa hydrostatic pressures was loaded for 4 hours per day, and lasted for 14 days. The cel s without hydrostatic pressure were regarded as the control group.
RESULTS AND CONCLUSION:Real-time quantitative reverse transcription PCR results showed that after osteogenic induction and simulated with 40 kPa hydrostatic pressure for 4 hours, the mRNA expressions of core binding factorα1 and osteocalcin in the bone marrow mesenchymal stem cel s were increased, while the mRNA expressions of peroxisome proliferator-activated receptorγ2 and adipsin were decreased, and the 80 kPa hydrostatic pressure did not cause such reactivity. The osteogenic induction effect of 40 kPa hydrostatic pressure could be partial antagonized with U0126. Histochemical staining showed that after simulated with 40 kPa hydrostatic pressure for 7 days, the expression and activity of alkaline phosphatase of bone marrow mesenchymal stem cel s were increased;after lasted for 14 days, the mRNA expressions of peroxisome proliferator-activated receptorγ2 and adipsin were increased. Certain intensity and duration of hydrostatic pressure stimulation can regulate the differentiation of bone marrow mesenchymal stem cel s, and the mechanism is only partly mediated by the extracel ular signal-regulated kinase 1/2 signaling pathway.

Objective To explore and analyze the executive function of patients with traumatic brain injury in recovery phase and reveal its influential factors.Methods Behavioral Assessment of Dysexecutive Syndrome (BADS) was conducted in 104 patients with brain injury at 5 ～ 6 months after discharging and matched healthy comparison subjects in this study.Basic information in patients with the clinical data were collected by self-designed questionnaire to analyze the relevant factors.Results BADS findings showed that the individual scores and total standard scores of brain injury patients( 12.05 ± 2.54 ) were significantly lower than those of health population ( 19.02 ± 3.77 ) (P ＜ 0.05 ).Action program test, temporal judgment test, modified six elements test and total sub-standard scores ( 14.83 ±3.86)in junior high school education level and below group were significantly lower than that in high school and higher education group ( 17.67 ± 4.10 ).The individual scores and total standard scores ( 10.13 ± 3.86 )in heavier group were significantly lower than that in the lighter group ( 15.68 ± 4.10 ).The group without complication' action program test, key search test, zoo map test, modified six elements test were significantly lower than the group with complication.The BADS scores were related to education, illness condition,and complication (hypertension, hyperglykemia, hyperlipemia) (P＜0.05).Conclusion There is executive dysfunction in traumatic brain injury patients.The executive dysfunction is mainly correlated with education, illnesscondition and complication.Medical staff should provide pertinent intervention and treatment according to the above aspects, in order to obtain better effects of rehabilitation therapy .

Objective:To observe the influence of valsartan combined with Bailing capsules on urinary albumin excretion rate in early stage of type 2 diabetic nephropathy ( DN) , and explore its protection in early DN. Methods:Sixty patients with early DN were randomly divided into two groups. On the basis of diet control and blood glucose regulation, the control group (n=30) was given valsartan 160 mg, qd, while the prevention group (n=30) was treated by valsartan (160 mg·d-1) combined with Bailing capsules (2. 0g, po, tid), and the treatment course was 12 weeks. The urinary albumin excretion rate ( UAER) , mean arterial blood pressure ( MAP) , serum creat-inine ( Scr) and hemoglobin A1c ( HbA1c) were measured and compared before and after the treatment in the two groups. Results:UAER in the two groups was significantly reduced after the treatment compared with that before the treatment (P<0. 01), and that in the prevention group was obviously lower than that in the control group (P<0. 01). MAP in the two groups was significantly decreased after the treatment as well (P<0. 01), while there was no significant difference between the two groups. Scr and Hb Alc in the two groups showed no significant changes before and after the treatment (P>0. 05). Conclusion:Valsartan combined with Bailing capsules shows certain effects in the treatment of early stage of type 2 diabetic nephropathy by decreasing the urinary albumin excretion.
