AIM: To observe the effects of hypoxia on the levels of nitric oxide (NO), endothelin (ET-1) and the expression of inducible nitric oxide synthase (iNOS) mRNA in human umbilical vein endothelial cells (HUVECs), and further investigate the mechanism of hypoxic pulmonary hypertension. METHODS: On the basis of the HUVECs culture model, the methods of nitrate reductase and radioimmunoassay were used to determine the changes of NO and ET-1 in the medium secreted by HUVECs, and the expression of iNOS mRNA was analyzed by semi quantitative RT-PCR after exposure to hypoxia (3% O_2) for 6, 12 or 24 h. RESULTS: The contents of NO_2-/NO_3-and ET-1 in hypoxia group in the medium was significantly higher than that in control group at different time points (P

Objective To explore the application value of 320-slice spiral CT myocardial perfusion technique in the evaluation of cardiac function in patients with coronary artery disease.Methods 24 patients with known reversible myocardial ischemia with coro-nary heart disease and 13 cases of normal were detected by 320-slice spiral CT myocardial perfusion scan in resting and after dobu-tamine-induced stress,measured the values of cardiac function indexes(ESV、EDV、SV、EF)in resting and after dobutamine-induced stress respectively,the results were analyzed by paired t test and independent sample t test,when the P value is less than 0.05,con-sidered statistically significant or correlation.Results The values of cardiac function indexes (ESV,EDV,SV)between the resting and after dobutamine-induced stress were significantly different except EF value in normal group.But only the EF value was signifi-cantly different in CHD,the rest values of cardiac function indexes(ESV,EDV,SV)no significant difference.Each corresponding value of cardiac function indexes in resting and after dobutamine-induced stress was significantly different between the CHD and the normal.Conclusion The dobutamine-induced stress myocardial perfusion with 320-slice spiral CT can judge the impaired degree of cardiac function in patients with myocardial ischemia,provide the basis for comprehensive evaluation of coronary artery disease and its prognosis.

Objective:To investigate the vasodilatative roles and mechanisms of 17 ? estradiol(E 2) on rat thoracic aortas (TA). Methods:Rings cut from thoracic aortas of female rats were used by in vitro perfusion. The endothelium dependent and endothelium independent vasorelaxing effects of E 2 were measured. Furthermore, it was also observed whether the relaxing effects of E 2 were modulated by tamoxifen, N ? nitro L arginine methyl ester(L NAME),TEA, methylene blue(MB) or Methylene Blue(MB).Results:E 2 caused acute concentration dependent relaxation in TA with endothelium, but not significant without endothelium( P

PURPOSE: Long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated as an oncogene in the development and progression of osteosarcoma. This study aims to explore the mechanism of NEAT1 in osteosarcoma. MATERIALS AND METHODS: Expressions of NEAT1 and miR-194 in osteosarcoma tissues and cells were detected by quantitative real-time PCR. The effects of NEAT1 knockdown or miR-194 overexpression on cell proliferation, invasion, and apoptosis were determined by 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide (MTT) assay, transwell invasive assay, and flow cytometry analysis, respectively. Luciferase reporter assay was performed to observe the possible interaction between NEAT1 and miR-194. RESULTS: NEAT1 was upregulated and miR-194 was downregulated in osteosarcoma tissues and cells. Knockdown of NEAT1 or overexpression of miR-194 suppressed proliferation and invasion and induced apoptosis of osteosarcoma cells in vitro. Luciferase reporter assay validated that NEAT1 could interact with miR-194 and negatively modulated its expression. Furthermore, inhibition of miR-194 reversed the suppression of proliferation and invasion and the promotion of apoptosis induced by NEAT1 depletion in osteosarcoma cells. CONCLUSION: Knockdown of NEAT1 suppressed proliferation and invasion and induced apoptosis in osteosarcoma cells by inhibiting miR-194 expression.

Objective:To introduce a novel ridge preservation technique with micro-titanium plate avoiding the use of bone grafting materials,and evaluate the potential horizontal bone preservation effect of this new technique,applied on single maxillary central incisors after tooth extraction for future implant restoration.Methods:Nine patients (six women and three men),mean age (26.0 ±5.7)years(from 1 8 to 34 years)referred to the Department of Oral Implantology,Peking University School and Hospital of Stomotology,were selected and diagnosed with unsalvageable single middle incisor with fine general con-ditions,no signs of acute local inflammation,no ongoing or previous periodontitis,healthy neighboring teeth and intact buccal bone walls.Tooth extraction,delayed implant placement and implant-supported single crown restoration were selected as treatment plan.The teeth were extracted atraumatically with lo-cal anesthesia,followed by a reflection of a minor flap to exposed 2-3 mm of the buccal bone plate.Af-ter that,a micro-titanium plate was trimmed and bended to fit the convexity of the labial bone and fixed by two mini pins with intent to support the labial soft tissue.The flap was then repositioned over the micro titanium plate and secured with two single sutures.No bone grafting materials or releasing incisions were needed.The sockets were left to heal without any intention of primary wound closure.Cone-beam compu-ted tomographic (CBCT)scans were obtained before and four months after tooth extraction.Horizontal ridge widths were measured with CBCT software,and the preservation effects were calculated and recor-ded by the percentage of horizontal ridge alteration.Results:The nine extraction sockets were healed un-eventfully.The average socket width before extraction was (7.51 ±0.48)mm (6.92-7.82 mm).The average alveolar ridge labial-palatal width at the control point of the edentulous area was (6.81 ±0.44) mm (6.04-7.38 mm)4 months after tooth extraction,the mean percentage of ridge width preserved was 90.87%±2.91%(87.28%-95.60%).Conclusion:This novel ridge preservation method by the usage of a micro-titanium plate did not interfere with the natural socket healing process,and at the same time,largely preserved the width of alveolar ridge without any bone grafting procedures.Long term results remain to be seen.

OBJECTIVE:
To study the relationship between lymphatic vessel density and clinicopathological features of laryngeal squamous cell carcinoma.
METHOD:
The lymph vessels, 40 specimens of LSCC and normal mucosa, were quantitated by SABC immunohistochemistry staining with lymphatic endothelial marker oncofetal antigen M2A Monoclonal antibody (D2-40).
RESULT:
The density of peritumoral D2-40(+) vessels in the LSCC group was higher than that of normal mucosa one (P<0.01). The density of peritumoral D2-40(+) vessels in T3/4 group was higher than that of T1/2 group (P<0.05). The density of peritumoral D2-40(+) vessels in the neck lymph nodal metastasis group was higher than that without neck lymph nodal metastasis group (P<0.05). The density of peritumoral D2-40(+) vessels in the supraglottic group was higher than that of glottic group (P<0.01). The density of peritumoral D2-40(+) vessels among high, middle, poor differentiation group were no significant difference (P>0.05).
CONCLUSION
Tumor lymph vessel mainly means peritumoral lymph vessel. The density of peritumoral lymph vessel marked with D2-40 in laryngeal carcinoma tissues was significantly correlated with progression and invasion of tumor.
