Objective To investigate the effects of ultraviolet blood irradiation and oxygenation(UBIO)on oxygen free radical metabolism(OFRM)in rabbits with acute soman intoxication.Methods One hundred rabbits were randomly divided into five groups:a control group,a soman intoxication group(I),a soman intoxication plus routine therapy group(TR),a soman intoxication plus UBIO therapy group(UBIO)and a soman intoxication plus complex therapy group(CT).All the rabbits were intervened accordingly.Then the concentrations of malondiade- hyde(MDA)and the activities of superoxide dismutase(SOD),glutathionperoxidase(GSH Px)and catalase (CAT)in serum were determined at 14 d after various treatments.Results Compared with the control group,the concentration of MDA and the activity of CAT in the 1 group were significantly increased(P＜0.01),while the activi- ties of SOD and GSH Px were obviously decreased(P＜0.05).After UBIO or complex therapy,the serum level of MDA was significantly decreased in comparison with that in the I group(P＜0.01),while the concentrations of SOD, GSH Px and CAT were enhanced(P＜0.05).Conclusion UBIO therapy can improve antioxidation activity against the injury caused by free radicals and could be used to treat acute soman intoxication,which causes injury from in- creased oxygen free radical concentrations.

Hemolytic diseases of newborn (HDN) can cause miscarriage, premature birth, fetal edema, fetal intrauterine anemia and even fetal death in early pregnancy. Neonatus with HDN can have jaundice, anemia, hepatosplenomegaly, edema and nuclear jaundice sequelae. This article reviewed the diagnosis and treatment of two patients with HDN caused by anti-E and anti-Ec combined with anti-Fyb, and reviewed the relevant literature on the epidemilogy, the diagnosis and treatment of HDN in order to improve the understanding of the disease.

OBJECTIVETo investigate the relationship between thrombolysis in myocardial infarction (TIMI) risk score and efficacy of different treatment strategies in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS).

METHODSFrom Oct. 2001 to Oct. 2003, 545 consecutive patients with NSTE-ACS were randomly assigned to early conservative strategy (n = 284) or early invasive strategy group (n = 261). The combined cardiovascular events (a combination of cardiac death, nonfatal myocardial infarction, nonfatal heart failure and re-hospital admission due to recurrent ischemia angina) within 30 days and 6 months were analyzed and related to the TIMI risk score at admission.

RESULTSRehospitalization due to recurrent ischemia angina of 30 days and the combined cardiovascular events of 30 days and 6 months were significantly lower in early invasive strategy group (3.5%, 10.0%, 21.1%) compared with early conservative strategy group (8.1%, 16.9%, 28.2%, all P < 0.05). Subgroup analysis indicated early invasive strategy could significantly decrease the 30 d incidence of the combined end point events in patients with high TIMI risk score and the 6 months incidence of the combined end point events in patients with moderate and high TIMI risk score (all P < 0.01), but the incidence was similar between the two different strategies in patients with low TIMI risk score.

CONCLUSIONSEarly invasive strategy may significantly reduce combined cardiovascular events in NSTE-ACS patients with moderate and high TIMI risk score compared with early conservative strategy.

BACKGROUNDEndovascular therapy plays an important role in the treatment of brain arteriovenous malformations (BAVMs). Ethylene vinyl alcohol copolymer (Onyx) is a novel liquid embolic material. This study aimed to summarize our experience of using Onyx for embolization of BAVMs with the focus on embolization technique.

METHODSFrom September 2003 to November 2007, 115 patients (43 women and 72 men, with a mean age of 29 years) with BAVMs were endovascularly treated with Onyx in our department. The following features of all AVMs were evaluated prior to treatment: type of nidus and shunt, draining veins, and feeding arteries. A total of 196 endovascular procedures were performed.

RESULTSThe course of endovascular treatment was completed in 88 patients. Additional sessions were planned in 27 patients. Of the 88 patients, total occlusion was obtained in 23 patients (26.1%), near-total (> 80% of the original volume) occlusion was obtained in 35 patients (39.8%) and partial occlusion (< 80% of the original volume) was obtained in 30 patients (34.1%) using embolization as the sole therapeutic technique. Mean volume reduction was 72% (range 30% - 100%) in 115 patients. Thirty four patients (38.6%, 34/88) underwent radiosurgical treatment. Additional embolization sessions were planned in 27 patients. Complications occurred in 19 patients (16.5%, 19/115), leading to death in one patient (mortality 0.9%) and permanent disabling in 3 patients (morbidity 2.6%).

CONCLUSIONSOnyx was shown to be feasible and safe for embolization of BAVMs. Proper use of the Onyx injection technique largely improved the endovascular treatment of BAVMs. Large AVMs can be adequately reduced in size through the use of additional treatment.

OBJECTIVETo investigate the effects of different X-ray doses on the expression of nuclear factor-kappaB (NF-kappaB) P65 in human oral squamous cell carcinoma cell (OSCC) line and the relationship between NF-kappaB P65 and radiation-induced OSCC cell line apoptosis.

METHODSThe squamous cell carcinoma of Tca8113 cell was cultivated in the 37 degrees C, 5% CO2 incubator after recovery. The experiment samples were divided into six groups (control group, 2, 4, 6, 8, 10 Gy). After growing to logarithm period, Tca8113 cells were irradiated using above-mentioned X-ray doses. The immunocyteochemistry and Western blot were used to detect the expression of NF-kappaB P65 after irradiation in various times (1, 3, 6, 10, 24, 48 h). The apoptosis rates under different radiotherapy dose were detected by flow cytometer and TDT-mediated dUTP-biotin nick end labeling (TUNEL).

RESULTSCompared with the control group, cytoplasm expression of P65 under different X-ray doses had statistically significant differences (P < 0.05). While the cytoplasm P65 protein expression at different time were compared each other, the 3 h group demonstrated significant difference (P < 0.05). Apoptosis rates in various groups, compared with control group, had statistically significant differences (P < 0.05). While the groups at different time points were compared each other, the apoptosis rates of 3 h group had significant differences (P < 0.05).

CONCLUSIONX-ray can activate the NF-kappaB P65 in oral squmaous cell carcinoma cell lines. The correlation between expressional quantity of P65 and radiotherapy induced apoptosis of oral squamous cell carcinoma cell lines possesses positive correlation. The activated and intranuclear P65 may have radiotherapy resistant effect.

OBJECTIVETo investigate the effect of different operation time to percutaneous balloon pulmonic valvuloplasty (PBPV) to critical pulmonary valve stenosis (CPS).

METHODTwenty-one infants (age ≤ 60 days at operating day) suffered from CPS, diagnosed by fetal echocardiogram and confirmed by echocardiography after birth, were enrolled in this case-control-study with written informed consent during April 2007 to December 2011. Of the 21 cases, 7 had prenatal diagnosis in our prenatal diagnosis center (prenatal group, Pre) and 14 were referred from other hospitals, who were divided into postpartum group A (Post A, referred within 28 days after birth) and postpartum group B (Post B, referred 29 to 60 days after birth). To Pre-group, the integrative interventional protocol was cautiously made by the consultative specialists, including intrauterine diagnosis, perinatal care and urgent PBPV soon after birth. To Post-group, emergency PBPV was preformed after the referral. Tei index of right ventricular and pressure-gradient (PG) between right ventricular and pulmonary artery were measured before and at different time points one year after PBPV.

RESULTThe values of SpO2 in Pre-group ranged from 82%-92% (86.57% ± 5.34%) under the state of continuous intravenous infusion of alprostadil. PBPV was successfully preformed within 3-6 days after birth. The values of SpO2 increased to 97.33% ± 1.15% post procedure. The values of PG pre- and post- procedure were (86.34 ± 11.77) mm Hg and (31.43 ± 8.46) mm Hg respectively. Preoperative RV Tei-index was 0.68 ± 0.05, it decreased rapidly after procedure, and recovered to normal one month after procedure. Only one case showed restenosis seven months after procedure and repeated PBPV. Fourteen referral cases (6 cases in Post A group and 8 cases in Post B group, accompanied in 1 and 3 cases with heart failure), the values of SpO2 ranged from 83%-91% under state of continuous intravenous infusion of alprostadil. And the operating time was 10-57 days after birth. The values of SpO2 recovered to normal post procedure, and heart failure alleviated. Increased preoperative RV pressure obviously decreased significantly post-procedure. And increased Tei-index declined gradually, at one-year follow-up, the value of Tei-index in Post A group recovered to normal, whereas that of Post B was (0.51 ± 0.06), compared to Pre and Post A groups, the difference was significant (P < 0.05) . One case showed restenosis nine months after procedure and repeated PBPV was performed. The hypoxic exposure durations were (4.43 ± 0.68) , (16.33 ± 4.46) , (41.25 ± 9.19) , respectively, and the difference among the three groups was significant (P < 0.05).

CONCLUSIONTo the fetuses with definite prenatal diagnosis of critical pulmonary valve stenosis, preoperative general condition can be adjusted to more suitable for emergency operation. Early PBPV can achieve shorter hypoxic exposure and better recovery of right ventricular function post procedure. Perinatal integrated intervention for CPS can significantly improve the prognosis and quality of life in this patient population.

BACKGROUNDAneurysms with wide-necked or a large neck/fundus ratio, especially located on an arterial bifurcation or a small artery, are challenges for interventional neuroradiologist because of the risk of coil migration or coil protrusion into the parent vessels. Our study was designed to improve the efficacy and safety of the "remodeling technique" with the HyperForm balloon for these difficult aneurysms and was confirmed by a follow-up result.

METHODSFrom June 2004 to September 2006, forty-two patients (20 men, 22 women) with wide-necked or large neck/fundus ratio aneurysms were treated by using the "remodeling technique" with the HyperForm balloon.

RESULTSForty wide-necked aneurysms were successfully treated with the HyperForm balloon remodeling technique with only two failed cases. Final results consisted of total occlusion in 34 cases (80.9%), subtotal in 4 (9.5%) and incomplete in 2 (4.8%). One aneurysmal rupture occurred, but no clinical consequence was shown. No thromboembolic events were observed during treatment. Final angiographic follow-up time ranged from 3 to 18 months.

CONCLUSIONSThe "remodeling technique" with the HyperForm balloon is a very useful tool in the treatment of wide-necked or unfavorable neck/fundus ratio intracranial aneurysms-located on an arterial bifurcation or a small artery and, especially, located on the bifurcation of a large artery and a small one. In our experience, this technique provided a safe and efficient treatment for difficult aneurysms when the standard remodeling technique might have failed.

Aim To primarily discuss the mechanism of Rhizoma Alismatis decoction on prevention and treatment of hyperlipemia,through investigating hepat-ic expressions of peroxisome proliferator activated re-ceptor-α(PPARα)and acyl CoA oxidase (ACO)in rats with hyperlipemia. Methods Fifty male Sprague-Dawley rats(160 ~ 180 g)were randomly divided into five groups:control group,model group,high-dose of Rhizoma Alismatis decoction group (H-RAD),low-dose of Rhizoma Alismatis decoction group(L-RAD), and Xue-Zhi-Kang group(XZK). Rats in control group were fed with ordinary forage,and the others were with high-fat forage,which lasted for four weeks. At the same time,high and low-dose of Rhizoma Alismatis decoction,as well as Xuezhikang capsule,was admin-istered in respectively designed groups. Then,the TC, TG,HDL and LDL of serum were detected,the mor-phology of liver tissues was observed with HE,and the expressions of PPARα and ACO were detected with RT-PCR and Western blot after four weeks. Results Rhizoma Alismatis decoction could significantly reduce serum concentration of TC,TG and LDL(P < 0. 01), while increasing the concentration of HDL(P < 0. 01) and strengthening the expressions of PPARα and ACO (P < 0. 01). Conclusion Strengthening the expres-sions of PPARα and ACO can be viewed as mecha-nisms of Rhizoma Alismatis decoction in prevention and treatment of hyperlipemia.
