The angiographic findings of 18 patients with vena cava syndrome were reported.The venacavographies showed the extent,degree of stenosis or obstruction,and collateral vascular dilatation.The vena cava displaced and stenosis suggested that there was space occupying lesion in the adjacency.The abdominal aortography could show streak like vessels supplying the tumor in the periphery of vena cava.The casuse,clinical feature and angiographic classification were briefly discussed.The angiography is considered an accurate method of diagnosing vena cava syndrome.

Objective To evaluate the imaging technique of magnetic resonance tomographic angiography (MRTA) in the investigation of etiology of hemifacial spasm (HFS). Methods Multiplane MRTA imaging of facial nerve of both sides was performed in all 121 HFS patients. Among them, 23 HFS patients received MVD subsequently. Results Among the 121 HFS patients, 119 patients had one side hemifacial spasm and 2 patients had double side hemifacial spasm,among them, neurovascular compression was found in the root entry zone (REZ) of facial nerve in 116 cases by MRTA,and the sensitivity was 94 3%;among the 119 cases which had no HFS,no neurovascular compression was found in the REZ of facial nerve in 112 cases by MRTA,and the specificity was 94 1%. Among 23 patients who received one side MVD, 21 patients had results that agreed with the multiplanar MRTA views. Conclusion Multiplanar MRTA was considered to be a very useful imaging technique for the study of etiology of HFS, and it also seemed to be a very important preoperative examination for MVD.

OBJECTIVE:To investigate the serumpharmacological effects of Compound Banmao Capsule(FBC)on prolif?eration of SMMC-7721cells in human hepatocellular carcinoma.METHODS:The effects of FBC were investigated in vitro using serum pharmacological approach.Different doses(clinic equivalent dosage,duplation and triplicity)of FBC suspension were irrigated into the rabbit stomachs.The inhibitory effects of FBC serum on SMMC-7721cells was observed by MTT assay.The inhibitory effects at different collecting hours in the clinical equivalent group were also observed.RESULTS:All of the drug serums in the three groups could inhibit the proliferation of SMMC-7721cells(P

The article of interventional therapy of hepatocellular carcinoma were reviewed including the method,basic research and the questions remained to be solved.All interventional therapies consisted of transcatheter arterial chemoembolism,transcatheter arterial heat infusion,transcatheter arterial heat embolism,Chinese medicinal herb,percutaneous ethanol injection,radiofrequencey ablation,percutaneous microwave coagulation and cryosurgery had their insufficiencies.The combined therapy,such as double chemoembolism,TACE combined with ablation,TACE combined with gene therapy could further promote the therapeutic effect.The research of the biological behavior of the residue after TACE was just at the beginning with problems still to be acknowledged.With the emerging of anti-oncogene therapy(P 53)and oncolytic virus therapy represented the gene therapy,together with anti-angiogenesis therapy,now the interventional therapy for hepatocellular carcinoma steps in a new stage.The treatment of during and perioperative periods possesses a great correlative influence with the therapeutic effect and complications and should be further standardized.

20%),but turning negative with 3 of them after 3 weeks.All the transplanted kidneys revealed different degrees of atrophy but 4 of them obtained chances of successful retransplantation 3-6 months after the procedure,3 of them with follow up of 1-3 years were being well.Conclusions Renal arterial embolization is a safe,efficient measure for treating post-transplanted renal failure with obvious decrease of correlative clinical symptoms and providing conditions for renal retransplantation.

[Objective ] To investigate the improvement of the surgical treatment effect on cerebral palsy with spastic diplegia by performing modified surgeries since 2004. [Method ] Twenty-three cases of severe cerebral palsy with spastic diplegia were operated, 14 male, 9 female; age 3 ～ 12 years; the average age of 5.7 years; their main symptoms were unable to stand and walk independently, with severe hypermyotonia of both lower extremities, and a scissoring type of gait when standing, hip and knee flexing contracture, ankle and foot equinovarus. Physical examination: there was hypermyotonia of the iliopsoas, adductor musculus, hamstrings, triceps surae, anterior and posterior tibial muscle, flexor pollicis longus and flexor digitorum longus. The muscle tone was 3 ～4 grade according to Ashworth criterion. Treatment: The intramuscular tenotomy, fascial division or sliding elongation were performed, to lengthen the tendon of the joint flexion contracture, the lateral half of anterior tibial muscle tendon was transferred laterally to balance the muscle force at the foot. Finally, both lower extremities were fixed by a new designed external frame, to straigthen the articular genu, keep both ankles and feet in neutral position, both lower extremities abducting 30°, and to correct all joint deformities. Family rehabilitation programs started after the external frame was removed 6 weeks later. [Result] All cases were followed up in 1 ～3 years with the average 2. 2 years. The results were evaluated as excellent, good and ineffective, according to correction of the joint deformities, the ability to stand and walk, and parent's satisfaction to the treatment. Of them 21 cases were excellent, 2 cases good, and no ineffective case. [ Conclusion ] For the severe cerebral palsy with spastic diplegia in children, reasonable release of the tight tendons of the multi-joint flexion contracture, balance of muscle force at the foot, correction of all deformities and fixation of the lower extremities with the new external frame, and long term of family rehabilitation after the surgery, are more effective treatment.

BACKGROUND: Recently,Illizarov external frame is commonly used to treat adult talipes equinovarus.However,its application is limited in infant and child due to amount of components,large volume and heavy weight. OBJECTIVE: A new three-dimensional external mini-frame was designed to observe its therapentical effects for congenital talipes equinovarus in infants. DESIGN,TIME AND SETTING: Retraspectively analysis of the therapentical effects of the three-dimensional external mini-frame for congenital talipes equinovarus in infants at the Department of Pediatric Orthopedics,Third Hospital of Hebei Medical University between January 2004 and June 2007. PARTICIPANTS: 106 infants (130 feet) with congenital talipes equinovarus,76 males and 30 females aged 1.6 years (range 0.5-3 years),including 80 left feet and 50 right feet,24 cases bilateral feet and 82 cases unilateral feet. Eighty-one cases underwent orthosis or cost treatment but were not cured; 10 cases underwent surgery in other hospitals but all failed,the other cases were not given any treatment. The new three-dimensional external mini-frame was designed by the authors and produced by Hebei Hengshui Kangda. METHODS: According to the age,degree of deformity,being operated or not and pathological changeS of the foot,different treatment methods were applied: Corrcetion and fixation of the foot directly with the new external mini-frame; Limited soft tissue release,followed by corrcetion and fixation of the foot with the mini-frame; Corrcetion and fixation of the foot with the mini-frame after more soft tissue realse on interior posterior foot; Corrcetion and fixation of the foot with the mini-frame after soft tissue release,tendon transfer and restore of muscle force balance. The postoperative external fixation lasted for about 3 mouths. MAIN OUTCOME MEASURES: Evaluatoin of therapentical effects according to Garceau standards. RESULTS: All cases were followed up for 2.5 years (range 0.5-3.5 years). Eighty-six cases (94 feet) were excellent: the foot looked near normal,the calcar pedis was erect,with plantigrade foot in walking,the range of the joint motion in foot was near normal. Seventeen cases (32 feet) were good: the foot deformity improved obviously,but a light adduction was remained in the forefoot,with plantigrade foot in walking,the range of joint motion in foot was good. Three cases (4 feet) were effective: the forefoot adduct lightly,with lightly calcaneus varus,the motion of foot was limitted partly. CONCLUSION: The new 3D external mini-frame shows favorable effects for congenital talipes equinovarus in infants.

[Objective]To explore the possible effects of the apolipoprotein A5(APOA5)gene rs2075291 and rs3135507 poly-morphisms on plasma lipid levels and the severity of coronary stenosis in patients with coronary heart disease(CHD)in Chinese Han people.[Methods]Polymerase chain reaction-restriction fragment length polymorphism method(PCR-RFLP)was used to identify the genotypes of the rs2075291 or rs3135507 polymorphism for the 324 patients with CHD and the 152 CHD-free controls,and the lipid levels between the genotypes were compared. The severity of coronary stenosis was assessed by the Gensini scoring system ,and the associations of the rs2075291 and rs3135507 polymorphisms as well as other factors with the Gensini scores were analyzed by mul-tivariate linear regression.[Results]The CHD patients had higher prevalence of hypertension ,and higher levels of triglycerides (TG),total cholesterol(TC),apolipoprotein B100(APOB100),lipoprotein(a)[Lp(a)],TG/high-density lipoprotein cholesterol (HDL-C),TC/HDL-C,low-density lipoprotein cholesterol(LDL-C)/HDL-C and APOB100/apolipoprotein AI(APOAI),and low-er levels of HDL-C and APOAI than the controls(P < 0.05 for all). The rs2075291 or rs3135507 allele and genotype frequencies were similar between the CHD group and the control group. The subjects with the rs2075291 GT genotype had higher levels of TG and TG/HDL-C,and lower levels of HDL-C than the subjects with the GG genotype in controls(P < 0.05 for all). In CHD patients, those with the rs2075291 GT genotype had higher levels of TG/HDL-C and TC/HDL-C than the patients with the GG genotype(P<0.05 for both). Regarding the rs3135507 polymorphism,the A allele carriers had lower level of APOB100 than the patients with the GG genotype(P<0.05). No significant association between the rs2075291 or rs3135507 polymorphism and the Gensini scores were detected by multivariate linear regression(P > 0.05).[Conclusion]The APOA5 rs2075291 polymorphism had significant effects on plasma lipid levels,but no effects on the occurrence and development of CHD. Further multicenter case-control studies with large samples are needed to validate these findings.

Objective To investigate the changes of expression of stromal cell-derived factor 1α (SDF-1α) in retinas after partial optic nerve injury in rats. Methods Models with injury of partial optic nerve were induced in rats. Retinal tissues were collected 1,2,3,5,7,10 and 14 d after injury. Enzyme linked immunosorbent assay and Real-time quantitative PCR were employed to detect the expression of SDF-1α protein and mRNA in retinal tissues respectively in injury group (n=28), sham operated group (n=28) and normal control group (n=12). Results The expression of SDF-1α protein and mRNA in retinas was higher than that in sham operated group and normal control group at different time points after injury (P<0.01), and it reached the peak at the 5th day after injury. The expression of SDF-1α protein and mRNA maintained a high level at the 14th day after injury. Conclusion The expression of SDF-1α protein and mRNA is up-regulated after partial optic nerve injury, and may last for a long time.

Objective To determine whether dopamine D5 receptor (D5R) regulates the development of dilated cardiomyopathy (DCM) by inhibiting oxidative stress.Methods We developed heart-specific hD5 mutant (α-MHC-hD5F173L) and wild type (α-MHC-hD5WT) transgenic mice.The NOX2 expression and ROS production were tested in the transgenic mice at three month of age.The α-MHC-hD5F173L mice were treated with either NADPH oxidase inhibitor Apocynin (1mmol/kg/day) or phosphate-buffered saline (PBS) as control by intraperitoneal injection for 4 weeks.After then, the indexes of heart function were measured.The hD5WT and hD5F173L were transfected respectively in rat H9C2 cells, in which ROS production and NOX2 expression were detected at basal level.Results The ROS production and NOX2 expression were higher in the heart of α-MHC-hD5F173L than α-MHC-hD5WT mice.Apocynin treatment improved the heart function of α-MHC-hD5F173L mice.NOX2 expression and ROS production were higher in hD5F173L than hD5WT transfected H9C2 cells.Conclusions Dopomine D5 receptor may prevent DCM development by inhibiting oxidative stress.
