Objective To investigate the responsiveness of the Burke Lateropulsion Scale (BLS) evaluating Pusher syndrome recovery and the characteristics of BLS. Methods 48 patients diagnosed as Pusher syndrome after stroke were included. All the patients were assessed with BLS to measure the progress at admission, every 2 weeks and at discharge, respectively. The characteristics of BLS score at admission and discharge and the standardized response mean (SRM) were analyzed. Results 56.3% patients were rated as mild and 16.7% were rated as severe at admission; none were classified as severe, 43.8% were not enough to be diagnosed as Pusher syndrome and 47.9% were classified as mild on discharge. SRM was 1.27 during the whole hospitalization, and SRM was 1.41 and 2.18 at 4 and 6 weeks, respectively. Conclusion BLS is an appropriate tool for the evaluation of patients with Pusher syndrome and is responsive to monitor the progress and recovery during rehabilitation.

Objective To explore the role of Toll-like receptor 7 (TLR7) and related signal transduction molecules in mechanisms underlying human papilloma virus (HPV) infection and condyloma acuminatum (CA) recurrence.Methods Peripheral blood was obtained from 30 healthy controls,35 patients with primary CA,32 patiens with recurrent CA and 30 patients with recurrent CA treated by imiquimod and ALA-PDT.Two-color flow cytometric analysis was used to detect TLR7 expression in different peripheral blood T cell subsets,Western blot to determine the expression levels of an adapter protein myeloid differentiation primary response gene 88 (MyD88),and signaling molecules including tumor necrosis factor receptor-associated factor (TRAF6),phosphatidylinositol3-kinase (PI3K),protein kinase B (AKT),p42/44 and nuclear factor-kappa B (NF-κB) in peripheral blood CD3+ T cells,from these subjects.Statistical analysis was carried out by Student's t test using the software SPSS 13.0.Results TLR7 was expressed in peripheral blood CD3+CD4+ T cells and CD3+CD8+ T cells from the healthy controls.Compared with the healthy controls,the patients with primary and recurrent CA showed no significant changes in TLR7 expression in CD3+CD8+ T cells,but a statistical increase in TLR7 expression in CD3+CD4+ T cells (23.3％ ± 8.4％ and 32.8％ ± 8.9％ vs.12.6％ ± 6.3％,t =4.72,10.76,both P ＜ 0.01).Decreased expression of TLR7 in CD3+CD4+ T cells was observed in patients treated with imiquimod and ALAPDT compared with the patients with recurrent CA (20.3％ ± 5.7％ vs.32.8％ ±8.9％,t =5.41,P ＜ 0.01).The protein expressions of MyD88,TRAF6,PI3K,p42/44 and NF-κB were significantly increased in CD3 + T cells,while the AKT protein expression experienced no significant changes in patients with primary or recurrent CA compared with the healthy controls.A significant decrease was observed in the protein expression of MyD88,TRAF6,p42/44 and NF-κB in the treated patients compared with those with recurrent CA.Conclusions TLR7,which is highly expressed in peripheral blood CD3+CD4+ T cells in patients with CA,may take part in the host immune response against HPV and serve as a recognition receptor for HPV infection.

Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.

Objective To study the CT findings of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods The CT examinations of 12 patients with pathologically proven pulmonary MALT lymphoma were reviewed retrospectively. Evaluated imaging findings included number, distribution,shape, attenuation and other associated findings of each lesion were evaluated. Results Thirty-two pulmonary lesions, including consolidations, masses, nodules and lesions with ground glass attenuation,were identified in 12 patients. Multiple lesions were founded in 10 of 12 patients and solitary lesion in 2 patients. Multiple lesions found in one lung in 2 patients, and multiple lesions found in both lungs in 8 patients. Ten cases demonstrated 21 consolidation lesions with air bronchogram, and one of the ten cases demonstrated two lesions with airway dilatation. Three cases demonstrated 5 masses or nodular lesions, 3 of these 5 lesions showed air bronchogram. Two cases demonstrated 6 ground glass attenuation lesions. One case showed mediastinal and hilar lymphadenopathy. Conclusion Pulmonary MALT lymphoma usually appears as multiple bilateral consolidations, masses, nodules with air bronchogram or lesions with groundglass attenuation at CT imaging. The imaging findings described above and with an indolent clinical course may suggest the diagnosis of pulmonary MALT lymphoma.

OBJECTIVETo compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.

METHODSFrom August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.

RESULTSThe overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.

CONCLUSIONCompared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.

[ABSTRACT]AIM:ToevaluatetheeffectsofantisenseTGF-β1oligodeoxynucleotide(ASTGF-β1)ontheex-pression of TGF-β1 , deposition of extracellular matrix ( ECM) and the neointima formation in the arteries after balloon inju-ry.METHODS:The unmodified and phosphorothioate-modified AS TGF-β1 which containing 15 bases and surrounding the initiation codon region (ATG) of rat TGF-β1 complementary DNA (cDNA) were designed.At the same time, sense TGF-β1 oligodeoxynucleotide ( S TGF-β1 ) with the base sequence complement to AS TGF-β1 was synthesized as a control . The oligodeoxynucleotides were introduced into in vivo and in vitro experiments , respectively .RESULTS:The AS TGF-β1 significantly inhibited the protein expression of TGF-β1 in a concentration-dependent manner , and S TGF-β1 did not have the same effect.Furthermore, no effect of the AS TGF-β1 on the mRNA expression of TGF-β1 in injured VSMCs was ob-served.Moreover, for the injured VSMCs, AS TGF-β1 significantly and concentration-dependently inhibited the basal DNA synthesis.Both AS TGF-β1 and S TGF-β1 did not exhibit dose-dependent effects on DNA synthesis in uninjured VSMCs . Fibronectin ( FN) mRNA expression in injured VSMCs was significantly decreased by AS TGF-β1 in a concentration (0.01~1 μmol/L)-dependent manner .AS TGF-β1 significantly increased the mRNA expression of contractile marker SM 22α, and decreased the mRNA expression of synthetic markers osteopontin and matrix Gla , especially at the concentration of 0.01μmol/L and 0.1 μmol/L.After treatment with AS TGF-β1 (90 μg· kg-1 · d-1 ) for 28 d, the neointima formation was significantly inhibited , and the area ratio of intima/media was markedly decreased by 68% compared with untreated group , but S TGF-β1 had no effect on neointimal formation .CONCLUSION:The AS TGF-β1 specifically inhibits the pro-tein expression of TGF-β1 in the VSMCs derived from injured arteries .Moreover , it significantly inhibits DNA synthesis and cell proliferation, and decreases the expression of FN .Therefore, AS TGF-β1 dramatically attenuates neointima formation after balloon njury .The effects of AS TGF-β1 on the injured VSMCs may be associated with its reverse effects on the altera-tion of VSMC phenotype after balloon injury .
