OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.

METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.

RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).

CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.

OBJECTIVETo study the correlation of multislice spiral CT features and vascular endothelial growth factor (VEGF) expressions and microvessel density (MVD) in renal cell carcinoma (RCC).

METHODSFourth-seven patients with pathologically confirmed RCC were examined by multislice spiral CT, and VEGF expressions and MVD of the RCC and the adjacent normal tissues were determined by immunohistochemistry with specific monoclonal antibodies.

RESULTSVEGF expression and MVD in the RCC and adjacent normal tissues increased with the pathological grades of RCC (P<0.05), VEGF expression was found to significantly correlate with MVD (r=0.67, P<0.01). The positive expression of VEGF and MVD were associated with the findings by multislice spiral CT scan of tumor size, intratumor necrosis, cystic degeneration, intensity signal, lymph node metastases, invasion of the renal vein or inferior vena cava, and invasion of the adjacent organs or distant metastases (P<0.01).

CONCLUSIONMultislice spiral CT findings can be indicative of the histopathology of RCC, and some CT findings are closely correlated with MVD and VEGF expressions in RCC, which may help evaluate the biological behavior and malignancy of the tumor and predict tumor invasion and metastasis.

Objective To investigate the immediate therapeutic effect of medicated thread moxibustion on cervical spondylosis.Methods Seventy patients with cervical spondylosis meeting the inclusion criteria were randomly allocated to treatment and control groups by using random number table method, 35 cases each. The treatment group received medicated thread moxibustion and the control group, percutaneous superficial needling. The Visual Analogue Scale (VAS) score and the Clinical Assessment Scale for Cervical Spondylosis (CASCS) score were recorded in the two groups before treatment and at 30 min and 24 hrs after treatment. The clinical therapeutic effects were compared between the two groups. Results The VAS and the CASCS scores decreased significantly in the two groups at 30 min and 24 hrs after treatment compared with before treatment (P<0.05,P<0.01). There was no significantly statistical difference in comparing the VAS score between the two groups after the treatment (P>0.05). The CASCS score was lower in the treatment group than in the control group at 30 min after treatment (P<0.01) and lower in the control group than in the treatment group at 24 hrs after treatment (P<0.05). At 30 min after treatment, the clinical therapeutic effect in the treatment group was superior to that in the control group (P<0.01); at 24 hrs after the treatment, the clinical therapeutic effect in the control group was superior to that in the treatment group (P<0.05).Conclusions Medicated thread moxibustion has a definite immediate therapeutic effect on cervical spondylosis.

Objective: To evaluate cardiopulmonary exercise testing (CPET) on sildenaifl effect for treating the patients with pulmonary arterial hypertension (PAH). Methods: A total of 25 PAH patients received sildenaifl treatment in our hospital from 2012-01 to 2014-01 were enrolled as PAH group, in addition, there were a Control group including 24 healthy subjects. The CPET, echocardiography, NYHA function class, 6-mimute walking distance (6MWD) and plasma levels of NT-proBNP at the baseline, (6-12) months and (13-18) months after sildenaifl treatment were assessed and compared between 2 groups. Results: Compared with Control group, PAH group showed decreased aerobic capacity (peakVO?2, Peak O2pulse) and ventilation efifciency (PETCO2@AT, VE?/VC?O2@AT), allP<0.05. At (8±2) months after sildenaifl treatment, aerobic capacity and ventilation efifciency was improved, meanwhile, NYHA function class, 6MWD and plasma levels of NT-proBNP were improved, allP<0.05. At (16±2) months after sildenaifl treatment, 6MWD was similar,P=0.26, while peak VO?2 and peak O2 pulse were decreased than they were at (8±2) months after sildenaifl treatment,P=0.04 and 0.06; the ventilation efifciency was elevated (as presented by increased VE?/VC?O2@AT and decreased PETCO2@AT,P=0.04 and P=0.04); plasma level of NT-proBNP was increased,P=0.05. Conclusion: CPET can effectively evaluate sildenaifl effect for treating PAH patients and therefore and guide the drugs therapy.

OBJECTIVETo detect the genes of Neisseria spp. isolated from patients with male genitourinary tract infections, and to study the pathogenicity of non-gonococcal strains of Neisseria and the laboratory diagnosis for the infections caused by Neisseria spp.

METHODSUsing polymerase chain reaction and nucleotide sequencing, we amplified and sequenced 4 genes of Neisseria spp. isolated from patients with male genitourinary tract infections, including 16S rRNA, orfl, cppB and nspA.

RESULTSFourteen Neisseria strains were identified through analysis of the 16S rRNA gene, including 3 N. mucosa strains, 3 N. cinerea strains, 2 N. gonorrhoea strains, 2 N. sicca strains, 2 N. subflava strains, 1 N. lactamica strain, and 1 N. polysaccharea strain. Among them, 9 showed positive results in gonococcal fluorescence-labeled multiplex-PCR detection, 1 in cppB gene reaction, 5 in orfl gene reaction, and 3 in nspA gene reaction. The consistency rate was 85.7% between the above results from our gene detection and those from the routine bacteriological methods.

CONCLUSIONThe cppB gene is absent in the non-gonococcal strains of Neisseria spp. that can cause male genitourinary tract infection. Most of the strains not only lack virulence-associated orfl and nspA genes, but also show positive results in gonococcal fluorescence-labeled multiplex-PCR detection, which is one of the important reasons for the misdiagnosis and missed diagnosis of gonorrhea infection. The combination of routine bacteriological methods and gene detection in laboratory examinations may help improve the accuracy rates of Neisseria species identification and clinical diagnosis of the infections caused by Neisseria spp.

OBJECTIVETo investigate the expression of CXCR3 and its association with clinicopathologic features in breast carcinoma.

METHODSThe expression level of CXCR3 in 18 samples of breast cancer and corresponding normal tissues was investigated using reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time RT-PCR analysis. Immunohistochemistry was carried out to examine the expression of CXCR3 in 80 breast cancers, 20 fibroadenomas and 15 normal breast tissues.

RESULTS(1) RT-PCR and real-time RT-PCR analysis showed a higher level of CXCR3 in breast cancer tissues than that in the corresponding normal breast tissues (P < 0.05). (2) Immunohistochemistry analysis showed that the positive rate of CXCR3 in breast cancer tissues was significantly higher than that in fibroadenomas and the normal breast tissues (P < 0.05). The expression level of CXCR3 in the lymph node-positive group was higher than that in the lymph node-negative group (P < 0.05). The expression of CXCR3 was positively correlated with the number of lymph nodes involved by metastasis, tumor size and pTNM tumor stage (P < 0.05).

CONCLUSIONSChemokine receptor CXCR3 was up-regulated in breast cancer, and was associated with the progression of breast cancer. CXCR3 might be a novel molecular marker to predict lymph node metastasis and prognosis of breast cancer.
