Background and purpose:The incidence of hepatoma is high. The outcome of treatment on hepatoma is poor.So we investigated the effect and mechanism of a selective cyclooxygenase-2 inhibitor celecoxib on the proliferation and apoptosis of SMMC-7721 hepatoma cell line. Methods:MTT assay was used to study the inhibitive effect of celecoxib on the growth of SMMC-7721 hepatoma cell. The effect of celecoxib on cell cycle and apoptosis on cells was studied by flow cytometry(FCM).Transmission electron microscopy (TEM) was used to display the morphological change of the SMMC-7721 hepatoma cell . The biochemical character of apoptosis was viewed on the agarose gel electrophoresis.The expression of bax gene and bcl-2 gene were measured by immunohistochemistry.Results:The SMMC-7721 cells were cultured in media that contained 25,50,75,100 ?mol/L celecoxib,by means of MTT, the inhibition rate was(15?3)%,(34.6?2.4)%,56.8?1.0)%,(86.2?0.4)% respectively after 24 hours; but the inhibition rate was (33.4?0.7)%,(66.7?1.8)%,(76.1?2.4)%,(97.3?0.8)% respectively after 48 hours(P

Objective: To observe the clinical efficacy of Zhi Shen Tiao Sui (regulating the mind and marrow) needling in treating depression after ischemic stroke. Methods: A total of 145 patients with depression after ischemic stroke were recruited between January 2016 and January 2018 and divided into two groups using random number table method, with 72 cases in the control group and 73 cases in the observation group. The control group received conventional treatment for ischemic stroke and medication, while the observation group was given additional Zhi Shen Tiao Sui acupuncture. The two groups were treated for 4 successive weeks. Clinical efficacy was analyzed after treatment. The neurological function pertinent scores [Hamilton depression scale (HAMD), clinical neurological deficit score (CNDS), activities of daily living (ADL), Fugl-Meyer assessment scale (FMA) and Barthel index (BI) scores], as well as the levels of cortisol (CORT) and adrenocorticotropic hormone (ACTH) were recorded in the two groups. Adverse reactions that occurred during treatment were also observed. Results: The clinical total effective rate was 82.2％ in the observation group, significantly higher than 66.7％ in the control group (P<0.05). After treatment, the HAMD and CNDS scores were markedly reduced in both groups (all P<0.05), and the ADL, FMA and BI scores were markedly increased (all P<0.05). The HAMD and CNDS scores were significantly lower in the observation group than in the control group after treatment (both P<0.05), and the ADL, FMA and BI scores were significantly higher in the observation group than in the control group (all P<0.05). The levels of CORT and ACTH declined significantly after treatment in the two groups (all P<0.05), and were markedly lower in the observation group than in the control group (both P<0.05). The adverse reaction rate was 2.7％ in the observation group, versus 4.2％ in the control group, and the between-group difference was statistically insignificant (P>0.05). Conclusion: Compared with sole use of Western medication, medication combined with Zhi Shen Tiao Sui acupuncture can promote the recovery of neurological function, down-regulate the levels of CORT and ACTH and enhance the clinical efficacy in treating patients with depression after ischemic stroke, with a relatively high safety rating.

In order to improve the sharing of DICOM, a proposal is offered to introduce XML into DICOM on the SPIE 2005 and in this way, better readability and expansibility of DICOM files have been achieved. On this basis, the DICOM data structure is improved further by replacing the one-dimension linear data structure with multilayer tree-shaped data structure. And thus the nesting and dependence relationships between information object and data elements are much clearer and it is more convenient and easy to browse DICOM image files.

Objective To investiagte the serum adiponectin concentration in preeclampsia and its relationship with serum leptin and soluble leptin receptor levels.Method The level of adiponectin,leptin and soluble leptin receptor in serum were measured by enzyme-linked immunosorbent assay(ELISA)in 38 patients with preeclampsia and 42 patients as control.The relationship of free leptin index(leptin/soluble leptin receptor) to preeclampsia was analyzed.Results There were no significant differences in maternal age,gestational age and body mass index(BMI)between two groups.But the gestational age and birth weight were significantly lower in preeclampsia than in control.The patients with preeclampsia had significantly higher levels of serum adiponectin, leptin and free leptin index(1691.7?g/ml,37.5 ng/ml and 0.95 respectively)than the control(689.4?g/ml, 19.3 ag/ml and 0.49,respectively).But there was no significant difference in serum level of soluble leptin receptor between the groups(35.0 ng/ml vs 42.2 ng/ml).Serum adiponectin was not significantly correlated with the level of leptin,soluble leptin receptor and free leptin index.Area of serum adiponectin,leptin and free leptin index in preeclampsia under the ROC curve were less than 0.5.Conclusions The patients with preeclampsia have paradoxical higher serum levels of adiponecfin and more bioavailability of leptin,suggesting these may be important factom of this complication.

Objective To compare the effect of right ventricular outflow tract (RVOT) and right ventricular apex (RVA) pacing on ventricular systolic synchrony using gated blood pool SPECT (GBPS).Methods A total of 50 patients implanted with pacemaker due to high degree or complete atria-ventricular block were enrolled in the study. Twenty-three patients were RVOT paced ( Group A, n = 23) and 27 were RVA paced (Group B, n=27). Twenty-four patients with malignancy, normal echocardiographic findings and no history of cardiac diseases were scheduled for pre-chemotherapy evaluation of cardiac structure and function and were enrolled as control group ( Group C, n = 24). All patients underwent GBPS imaging and the values of phase angle (PS), mean phase of each wall, standard deviation (SD) of mean phase of each wall, lateral-septal motion delay of left ventricle ( LV Sep-Lat Delay), septal-right ventricular (RV) delay of LV ( LV Sep-RV Delay) and LV-RV Delay were acquired. The parameters of ventricular systolic synchrony among the three groups were compared using one-way ANOVA. Results The mean phase of LV lateral wall in Groups A and B were significantly higher than that in Group C: Group A (120.50 ±40.58) ms; Group B (103.23±28.34) ms; Group C (84.63 ±22.38) ms (F=7.72, P ＜0.05). There was no significant difference between Groups A and B ( t = 1.30, P ＞ 0.05 ). The mean phase of RV in Group A was significantly larger than those in Groups B and C: Group A ( 137.05 ± 39.27) ms, Group B ( 100.85 ± 23.79) ms,Group C (59. 13 ±30.52) ms (F=35.55, P＜0.05). PS, SD and LV Sep-Lat Delay in Groups A and B were significantly higher than those in Group C: (85.73 ± 12.00)°vs (89.85 ± 15.61 )°vs (58.95 ±9.87)°, (27.68±10.66) ms vs (26.15 ±13.02) ms vs (15.63 ±8.35) ms, (25.06±34.23) ms vs (2. 62 ± 60. 31 ) ms vs ( - 23.66 ± 31.39) ms, F = 41.54,8.55,6.81, all P ＜ 0.01 ), however, there was no significant difference between Groups A and B ( t = 0. 68, 0.68, 1.30, all P ＞ 0.05 ). LV Sep-RV Delay and LV-RV Delay were significantly different among the three groups ( LV Sep-RV Delay: Group A (57.60 ±56.77) ms, Group B (6.36 ±61.88) ms, Group C ( -41.89 ±35.78) ms; LV-RV Delay:Group A (47.36 ±42.59) ms, Group B ( 3.08 ± 38.81 ) ms Group C ( - 26.50 ± 20.99 ) ms, F = 20. 32,25.38, both P ＜ 0.01 ). Conclusion Both RVA and RVOT pacing increase the segmental phases detected by GBPS, causing inter- and intra- ventricular asynchrony compared with patients without pacemakers.

OBJECTIVETo evaluate the safety and efficacy and summarize the initial experience of transcatheter mitral valve repair (TMVR) for treating Chinese patients with severe mitral regurgitation.

METHODSIn May 2012, TMVR using MitraClip system was applied in 3 patients with severe mitral regurgitation. One patient suffered from with mitral valve prolapse and two with functional mitral regurgitation. The efficacy and complications of the procedure were analyzed.

RESULTSTMVR procedure was successful in all 3 cases. NYHA classification improved by 1 grade in 2 patients and 2 grades in one patient. The mean operation time was (105 ± 38) minutes and X-ray exposure time was (10 ± 4) minutes. Mean aortic pressure was increased from (62 ± 18) mm Hg (1 mm Hg = 0.133 kPa) to (75 ± 14) mm Hg, and mean left atrial pressure was significantly reduced from (15 ± 10) mm Hg to (9 ± 5) mm Hg immediately after the deployment of MitraClip. Three days after the procedure, left ventricular diastolic dimension decreased from (63 ± 11) mm to (59 ± 10) mm, left atrial dimension declined from (59 ± 11) mm to (51 ± 8) mm, and NT-ProBNP was reduced from (4292 ± 1137) mmol/L to (1187 ± 489) mmol/L. No complications occurred in all three cases.

CONCLUSIONSOur initial experience showed that TMVR using MitraClip system is safe and effective for patients with severe mitral regurgitation. However, the long term benefit of the procedure should be validated through follow up.
