Objective To examine the effects and mechanisms of simvastatin and fenofibrate, and combination of the two drugs on the expression of apolipoprotein M (apoM). Methods The male C57BL/6N mice ( n =32) were random divided into four groups, including control group (with no special treatment), statin group (with simvastatin [10mg/( kg · d) for 4 weeks], fibrate group (with fenofibrate [100mg/( kg · d) for 4 weeks] and combination group ( with simvastatin [10mg/( kg· d)] and fenofibrate [100mg/( kg · d) for 4 weeks]. The levels of apoMmRNA and protein, hepatic nuclear factor (HNF-1α)mRNA, liver X receptor-α (LXRα) mRNA in mouse liver were measured. Results Both of simvastatin and fenofibrate can increase the expression of apolipoprotein M ( 1.97 ± 0. 04,2. 02 ± 0. 02 ) and HNF-1αmRNA ( 1.74 ± 0. 05,1.71 ± 0. 04). Combination group obtained more effects than either single agent ( P ＜ 0. 05 ). Simvastatin could decrease the expression of LXRα mRNA ( 1.00 ± 0. 02 ) ( P ＜ 0. 05 ). Fenofibrate could increase the expression of LXRα mRNA(2. 80 ±0. 04) ( P ＜0. 05). No significant difference in LXRα expression was seen between combination( 1.56 ±0. 03 ) and control group( 1.53 ±0. 03 )( P ＞0. 05). Conclusions Simvastatin and fenofibrate can increase apoM expression. Treatment with combination of the two drugs is more effective, and the mechanism might be related to the regulation of HNF-1α and LXRα.

Objective To explore the value of stress dual-phase (early and delayed phases)18 FFDG myocardial PET/CT in detection of myocardial ischemia.Methods Ten swine were prepared as ischemic models and underwent 3 imaging procedures:pre-model stress (8 swine),post-model rest (8 swine)and post-model stress dual-phase imaging (10 swine).To perform stress dual-phase imaging,the tested subjects were fasted for more than 12 h and underwent early-phase PET imaging at 50 min after the intravenous injection of 18F-FDG (5 MBq/kg) for 10 mins,and followed by a dobutamine stress test,and then delayed-phase PET imaging at 50 min after the stress test for another 10 mins.The post-model rest dual-phase imaging was performed in almost the same way except that there was no dobutamine-loading.18F-FDG uptake image was qualitatively analyzed and classified into 4 levels:1 =no uptake,2 =diffuse uptake,3 =focal uptake,4=focal on diffuse uptake.Level 1 or 2 was considered as normal.If the focal uptake (level 3 or 4)was found on anterior wall or septum,ischemia was diagnosed.x2 test was used to determine the difference of the rate of ischemic myocardium between the two phases.18F-FDG uptake ratio of the anterior wall to posterior wall (K) of the left ventricle was calculated (K1 for early phase and K2 for delayed phase).Wilcoxon rank sum test was applied to determine the difference between K1 and K2.Results CAG showed LAD stenosis ＞70％ in all swine.In pre-model stress dual-phase imaging,no ischemia was detected at two phases (8/8 for level 1 or 2,0 for level 3 or 4).There was no significant difference between K1 and K2(1.08±0.10,1.11 ±0.10; Z =-1.48,P＞0.05).In post-model rest dual-phase imaging,the rate of ischemic myocardium was not significantly different between early and delayed phases (1/8,3/8 ; x2 =0.50,P＞0.05).There was no significant difference between K1 and K2(1.47±0.28,1.28±0.40; Z=-2.02,P＞0.05).In post-model stress dual-phase imaging,the rate of ischemic myocardium between the two phases was statistically different (4/10,10/10;x2=4.17,P＜0.05),and the difference between K1 and K2 was also significant (1.55±0.32,1.86±0.39; Z=-2.49,P＜0.05).Conclusion Stress dual-phase 18F-FDG myocardial PET/CT might be useful for the diagnosis of ischemia.

OBJECTIVETo explore the effect of Tongfu Jinghua Decoction (TJD) on hemodynamics and tissue oxygen metabolism in patients with post-traumatic sepsis shock.

METHODSTotally 60 patients were randomly assigned to the treatment group and the control group, 30 in each group. Patients in the treatment group took TJD or were administered with TJD by nasal feeding in combined with conventional Western medical treatment, while patients in the control group only received conventional Western medical treatment. Changes of each index in hemodynamics and tissue oxygen metabolism were observed before treatment, and at 6, 12, 24, and 48 h after treatment.

RESULTSCompared with before treatment in the same group, hemodynamic changes were significantly improved at each time point in the two groups. All indices of tissue oxygen metabolism at each time point of the two groups were significantly improved, except changes of O2 extraction ratio (ER) after treatment in the control group (P < 0.05, P < 0.01). Compared with the control group in the same period, heart rate (HR), systemic vascular resist- ance (SVR), and cardiac output (CO) were significantly improved with statistical difference (P < 0.05, P < 0.01). Mean arterial pressure (MAP), central venous pressure (CVP), and cardiac index (CI) were significantly improved at 6, 12, and 24 h after treatment with statistical difference (P < 0.05, P < 0.01). Each index of tissue oxygen metabolism in the treatment group were all improved at each time point with statistical difference (P < 0.05, P < 0.01).

CONCLUSIONTJD combined with conventional Western medical treatment could quickly improve hemodynamics and tissue oxygen metabolism disorder in patients with septic shock, and its curative effect was superior to that of conventional Western medical treatment alone.

Objective To explore the application value of triggered angiography non-contrast enhanced (TRANCE) technology in diagnosing lower limb arterial occlusive disease.Methods Totally 22 lower limb arterial occlusive disease patients were randomly selected,and then underwent TRANCE and DSA examinations.The arteries from the abdomen to the lower limb were divided into abdominal aorta,common iliac artery,external iliac artery,internal iliac artery,superficial femoral artery,deep femoral artery,popliteal artery,anterior tibial artery,posterior tibial artery and peroneal artery.Totally 337 sections displayed clearly were chosen to go through examinations by TRANCE and DSA.Results Of the 337 sections there were 312 ones with the same stenoses found by TRANCE and DSA,TRANCE found 16 sections with worse stenoses and 9 milder ones than by DSA.There were 153 sections with the same moderate stenoses (≥50％) displayed by TRANCE and DSA;Of the 153 sections,there were 15 ones with worse stenoses and 6 ones with milder stenoses found by TRANCE than by DSA.Kappa value of the two methods was 0.905.Conclusion TRANCE technology is a non-invasive,safe and nonradiative diagnosing method for the lower limb arterial occlusive disease.

Objective To assess the feasibility and clinical results of video-assisted high anterior transcervical approach (Smith-Robinson) in treatment of spinal lesions of the craniovertebral junction. Methods Between April 2007 to October 2009, nineteen consecutive patients with spinal lesions of the craniovertebral junction were included in the study. There were 9 males and 10 females aged from 16 to 62 years old with a mean of 32 years. The primary pathologies included 4 cases with chronic odontiod fracture, 2 cases with purely irreducible atlantoaxial dislocation, 6 cases with os odonteideum, 1 case with Marfan synd rome, 1 case with primary basilar invagination from Kippel-Feil syndrome, 3 case with axis tumor and 1 case with irreducible rheumatoid atlantoaxial dislocation. All of the patients underwent combined video-assisted high anterior transcervical procedure and posterior fixation at one-stage. The anterior procedure included atlantoaxil release and reduction (8 cases), odontoidectomy (8 cases), and intralesional extracapsular excision and reconstruction (3 tumor cases). The posterior technique were C1-C2 pedicle screw fixation (13 cases), C1-C3 pedicle screw fixation (2 cases), and occipitalcervical fusion (4 cases). Results Anatomical reduction was achieved in eight cases with anterior release and reduction. Tumors were completely removed in three cases with axial tumor. The mean follow-up was 14 months (6-36 months). All of them achieved solid bone fusion. In the 14 patients with symptoms of spinal cord dysfunction, the average Japanese Orthopaedic Association (JOA)score had improved from 9.1±3.3 preoperatively to 14.1±2.9 postperatively. The improvement rate was excellent for 7 cases, good for 5 cases, fair for lcase and poor for 1 case. One patient experienced leakage of cerebrospinal fluid which was resolved by bioprotein gelatin blocking and lumbar subarachnoid continuous drainage within 1 week. Dysphagia which occurred in 3 cases responded well to dexamethason and mannitol.No infection and hardware failure were observed. Conclusion Video-assisted high anterior transcervical procedure is a safe and effective alternative for treating spinal lesions in the craniovertebral junction.

Congenital cataract is a highly heterogeneous disorder at both the genetic and the clinical-phenotypic levels. A unique cataract was observed in a 4-generation Chinese family, which was characterized by autosomal dominant inheritance and late-onset. Mutations in the 13 known genes (CRYAA, CRYAB, CRYBB1, CRYBB2, CRYGC, CRYBA1/A3, CRYGD, Connexin50, Connexin46, intrinsic membrane protein LIM2, cytoskeletal protein BFSP2, the major intrinsic protein-MIP and the heat shock factor HSF4) have previously been demonstrated to be the frequent reason for isolated congenital cataracts, but the exact molecular basis and underlying mechanisms of congenital cataract still remain unclear. This study was designed to find whether these 13 genes developed any mutation in the family members and to identify the disease-causing gene. Polymerase chain reaction (PCR) and direct DNA sequence analysis were carried out to detect the 13 genes. The results showed that no mutation causing amino acid alternations was found in these potential candidate genes among all patients in the family, and only several single-nucleotide polymorphisms (SNPs) were identified. A transitional mutation in the fourth intron of CRYBB2 and some silent mutations in the first exon of BFSP2 and CRYGD were found in the cataract family, but further study showed that these mutations could also be found in normal controls. It was concluded that some unidentified genes may underlie the occurrence of late-onset cataract in this family. A genome-wide screening will be carried out in the next study.

Objective To evaluate carotid intima-media thickness(IMT) and elasticity in patients with pregnancy-induced hypertension(PIH) using ultrasound radio-frequency data(RF-data) technology.Methods Twenty-seven PIH women(mean brachial blood pressure:108 mm Hg,1 mm Hg=0.133 kPa)were included and thirty age- and gestational week-matched normal pregnant women served as controls.Carotid IMT and stiffness were evaluated using quality IMT(QIMT) and quantitative artery stiffness(QAS)techniques with color Doppler.Results Carotid IMT and elasticity parameters,including pulse wave velocity,pressure at T1,arterial augmented pressure(AP) and arterial augmented pressure index(AIx) were significantly higher in PIH group than in the normal group[IMT:(466.84±118.50)μm vs (386.58±125.79)μm;PWV:(7.09±1.97)m/s vs (5.95±1.11) m/s;PT1:(127.50±14.29) mm Hg vs (105.89±11.02)mm Hg;AP:(5.14±3.39) mm Hg vs (1.98±2.19)mm Hg;AIx:(7.58±8.73)% vs (-4.79±7.92)%)], and there were significant differences(t=2.660,2.660,3.460,3.460,3.460,all P＜0.01).Conclusions PIH women have significantly increased carotid IMT and decreased elasticity compared with normal pregnant women.Radio-frequency technique could reliably reflect the changes of the carotid arterial structure and elasticity in patients with pregnancy-induced hypertension.

Objective To investigate the effect of combined treatment of p15 gene transfection with arsenic trioxide(As_2O_3)on proliferation and apoptosis of human squamous esophageal carcinoma cell line EC109.Methods Plasmid pcDNA3.1(+)-p15 was introdueted into EC109 cell hy the lipo- somes.As_2O_3(2?mol/L)was added to stable transfeeted cells for succedent experiments.The existence of exogenous p15 gene eDNA and the expression of P15 protein were assayed by PCR and Western blotting,respectively.The proliferation and apoptosis were measured by means of MTT,colony forma- tion assay,transmission electron microscopy,The cell cycle and population of apoptosis were measured by flow cytometry.Results After transfection,p15 gene mRNA and protein expressed in EC109 cells. Combined p15 transfection with As_O_3,the EC109 cell growth and colony formation were significantly decreased(P＜0.05,P＜0.01),compared with either p15 transfected group or treated with As_2O_3 group.After combining p15 transfection with As_2O_3 for 3 days,EC109 cell cycle was more arrested at G_1/S.The population of G_1 phase cells was significantly increased(P＜0.05),the population of S phase cells was significantly decreased(P＜0.05),and the population of the apoptosis cells was significantly increased(P＜0.01),compared with either p15 transfected group or treated with As_2O_3 group.More obvious apoptosis was found in the group with combined treatment of p15 gene transfection and As_2O_3 by transmission electron microscope.Conclusion p15 gene transfection combined with As_2O_3 show a signifi- cant effect on enhancing proliferation inhibition and could induce more apoptosis on EC109 cells in vitro.
