Objective To investigate the distribution of blood pressure and incidence of hypertension in children and adolescents from the urban area of Guiyang city aged 8-17 years old,in order to provide scientific evidence for preventing hypertension.Methods Seven thousand nine hundred and sixty-three primary and secondary students were sampled and standardized in blood pressure,height and weight.In accordance with the Working Group on Obesity in China(WGOC)recommendations,the subjects were divided into overweight,obesity and normal weight group,then the relationship between blood pressure and body mass index(BMI)and the prevalence of hypertension in different BMI groups were analyzed.Results 1.Compared with the USA and Shanghai city,the distribution of blood pressure in children and adolescents from the urban area of Guiyang city were different(Pa

Objective To investigate the protective effect and mechanisms of NF-?B decoy oli- godeoxynucleotides(ODNs)on rat liver graft following ischemia-reperfusion injury.Methods Ani- mals were randomly divided into 3 groups(n=8 in each group):control group,ischemia-reperfusion (IR)group,and decoy ODNs group,in which donor grafts were transfected with 120?g NF-?B decoy ODNs before graft procurement.Following 2 h of reperfusion,Kupffer cells(KCs)were isolated,and NF-?B biding activity was detected with electrophoretic mobility shift assay(EMSA),and TNF-?、IL- 6 mRNA expression was assayed by using RT-PCR method.Meanwhile,the liver and serum samples were collected,the histopathologic change of liver was examined by light microscope,and liver func- tion was analyzed.Results The NF-?B biding activity,TNF-?,IL-6 mRNA expression,and the ALT,TBIL levels in serum were significantly increased following 2 h of reperfusion in IR group as compared with those in control group(P＜0.01).A large amount of degeneration and necrosis in hep- atocytes accompanied with obvious congestion in hepatic sinusoid occurred.However,these tested in- dexes were significantly ameliorated in decoy ODNs group as compared with those in IR group(P＜0.01),and the architecture of hepatic lobules was remained.Conclusions KCs NF-?B activation fol- lowing reperfusion plays an important role in IRI in liver transplantation.Decoy strategy shows appar- ent effect on suppression of NF-?B activation,and thus inhibits the production of downstream cyto- kines,which protects the liver graft from IRI.

Objective To evaluate the diagnostic value of magnetic resonance tomographic angiography(MRTA) with 3.0T scanner for neurovascular compression in patients with trigeminal neuralgia and hemifacial spasm.Methods MRTA using three-dimensional time-of-flight(TOF) sequence was performed in 52 cases with trigeminal neuralgia and 9 cases with hemifacial spasm.MR oblique sagittal and coronal images were created to display the relationship between trigeminal and facial nerves and surrounding vessels,and compared with that of operation MRA showed that.Results In 52 cases with trigeminal neuralgia,the trigeminal nerves were compressed by vessels or contacted with vessels in 46 cases at MRTA,and in 9 cases with hemifacial spasm,all trigeminal nerves showed having vascular compression or in contact with vessels.The accuracy,sensitivity and specificity of MRA in diagnosing trigeminal neuralgia and hemifacial spasm caused by vascular compression were 90.2%,96.4% and 80%,respectively,which compared with that of operation.Conclusion MRTA is sensitive to neurovascular compression,which plays an important role in diagnosing trigeminal neuralgia and hemifacial spasm.

Background: Endoscopic surgery of Western medicine has developed rapidly in treating ureteral calculi while traditional Chinese medicine (TCM) therapy also has its advantage, thus the integrated traditional Chinese and Western medicine therapy may have an even better efficacy in dealing with this problem. Objective: To observe the clinical effects of sequential therapy of Quantong Recipe, a compound traditional Chinese herbal medicine, combined with ureteroscopic laser lithotripsy on ureteral calculi. Design, setting, participants and interventions: A total of 151 patients with ureteral calculi (stone diameter of 3 to 21 mm) from Department of Urology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine were included, of which 106 patients with stone diameter of 3 to 10 mm were treated with Quantong Recipe for the first two weeks. Twenty patients with unexpelled stones and 45 patients with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy. The 65 patients except one open operation were divided into regular treatment group (32 cases) and regular treatment combined with Quantong Recipe group (32 cases) after lithotripsy. The efficacy was assessed after one week. Main outcome measures: Cure rate in the patients with stone diameter of less than 10 mm after two-week Quantong Recipe treatment was calculated, and clearance rate in the patients with residual stone for ureteroscopic laser lithotripsy after one-week Quantong Recipe treatment was also observed. Results: After taking Quantong Recipe for two weeks, the stones in 86 patients were completely discharged, and the stones in 6 patients were not completely discharged, but the unexpelled stones had moved down more than one segment of ureteral stenosis; the total response rate was 86.79% (92/106). The 64 patients with stones unexpelled or with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy, and the clearance rate of residual stone was 93.8% in regular treatment combined with Quantong Recipe group, and was 71.9% in regular treatment group, and there was a significant difference between the two groups (P<0.05). Conclusion: Sequential therapy of Quantong Recipe integrated with ureteroscopic laser lithotripsy demonstrates a significant advantage of integrated traditional Chinese and Western medicine therapy in treating ureteral calculi.

Objective To systematically review the existing evidence about the effect of medial and lateral (crossed) entry pins versus only lateral entry pin fixation on the supracondylar fractures of the humerus in children.Methods Eligible studies were identified in Cochrane library,the Cochrane Bone,Joint and Muscle Trauma Group (till March 2011 ),Medline (from 1966 to March 2011 ),EMbase (from 1966 to 2011 ),CBM (from January 1979 to March 2011 ),PubMed,Wanfang Data (from 2000 to March 2011 ) and CNKI and the references of the included studies and several Chinese orthopedic journals were manually searched.Then,the randomized controlled trials (RCTs) and quasi-randomized controlled trials (CCTs) about two entries (crossed and only lateral pinning) for supracondylar fractures of humerus in children were collected.After evaluation of methodology with the enrolled studies,available data was extracted and systematic review was conducted via the method recommended by the Cochrane Collaboration.Results In total,five RCTs involving 311 patients were involved.Compared with the preoperative data,the meta-analysis results showed no significant difference in reduction stability in terms of change in Baumann angle and Carrying angle between the two groups.For the postoperative function outcome including complete reduction,Flynn grade and full return to function,no significant difference was found between the two groups.For the postoperative complications,there was no difference in the infection of pin tract,though lateral entry resulted in a significant lower incidence of the iatrogenic nerve injury compared with the medial and lateral entry.Conclusions With the Kirschner wire fixation for supracondylar fractures of humerus in children,current existing evidences indicate that the lateral entry of pinning has similar results in reduction stability,function outcome and incidence of pin tract infection compared with medial and lateral entry.Nevertheless,lateral entry,as a safe pinning technique,may effectively decrease the risk of iatrogenic nerve injury

Objective To investigate the effects of heart displacement on hemodynamics during off-pump coronary artery bypass grafting (OP-CABG) while the sites for anastomosis were being exposed. Methods Forty-seven patients of both sexes (36 male, 11 female) aged 50-82 years undergoing OP-CABG were enrolled in the study. Preoperative cardiac function was assessed : class Ⅱ in 22 patients; Ⅲ in 23 and Ⅳ in 2 according to NYHA classification.The mean ejection fraction was 0.55?0.14 before surgery.They received on average 3.2 grafts. Premedication consisted of intramuscular morphine 10 mg, midazolam 3-5 mg and scopolamine 0.3 mg.Before induction of anesthesia ECG and SpO2 were monitored and radial artery was cannulated for continuous direct BP monitoring. Anesthesia was induced with midazolam 0.1 nig?kg-1 , fentanyl 4?g?kg-1 and pancuronium 0.1 mg?g-1 iv.The patients were mechanically ventilated after tracheal intubation and PETCO2 was maintained at about 40 mm Hg. Anesthesia was maintained with isoflurane and 50%-60% N2O in O2 and intermittent intravenous boluses of fentanyl and pancuronium. Swan-Ganz catheter which can continuously monitor mixed venous blood O2 saturation (SvO2) was placed in pulmonary artery via right internal jugular vein. SvO2, cardiac output (CO), BP, pulmonary arterial pressure (PAP) and HR were continuously monitored. Right atrial pressure (RAP) and PAWP were measured intermittently. Cardiac index (CI),stroke index (SI),systemic vascular resistance index (SVRI),PVRI, left and right ventricular work index (LVWI,RVWI) and left and right ventricular stroke work index (LVSWI,RVSWI) were calculated. The hemodynamic parameters were recorded after induction of anesthesia before surgery (T1,baseline),before heart displacement (T2), while anastomosis to anterior descending branch was being made (T3), while anastonosis to right coronary artery or posterior descending branch (T4) and to left circumflex artery or diagonal branch (T5) was being made, after normal heart position was resumed (T6) and at the end of operation (T7). Results While anastomosis to the anterior descending branch was being made (T3) SI and LVSWI significantly decreased as compared with the baseline (P

This article provides the possible mechanism of acupuncture-moxibustion repair of gastric mucosal injury from central regulation and puts it forward that the nucleus of solitary tract is the primary regulation center for the injury repair and has the effect of collecting and integrating information. In addition, it is put forward that neural regulation is a main regulatory mechanism for the injury repair and besides, endocrine, immune and humoral regulations participates in the modulation and gastric mucosal repair involves a composite regulatory mechanism in which the central nervous system, neuroendocrine-immune network and neurohumoral regulation take part.

AIM: To establish hybrid mouse embryonic stem (ES) cell line from blastocysts of the (C57BL/6J × 129/J) F1 mouse. METHODS: 3.5 days post- coitus (d.p.c.) blastocysts were cultured on mouse embryonic fibroblasts (MEFs) in the medium, after 3 - 4 days, Inner cell mass were picked up and disaggregated, then reseeded. After the ES - like colonies appeared, passaged them to give permanent ES cell lines. The pluripotent propertes of ES cells obtained were analyzed by alkaline phosphatase (AKP) activity, expression of SSEA- 1 and Oct-4, and their capacity to form teratoma. RESULTS: Two hybrid ES cell lines, SC1001, SC1002 were obtained from blastocysts of the (C57BL/6J × 129/J) F1 genotype. Most of these ES cells had a normal karyotype and an XY sex chromosome composition. The pluripotent properties of the cell lines were analyzed on the basis of their alkaline phosphatase activity, expression of SSEA - 1 and Oct - 4, and their capacity to form teratoma in severe combined immunodeficiency (SCID) mice. CONCLUSION: Two hybrid mouse ES cell lines having pluripotent properties and capacity for long - term self renewal were generated from blastocysts of the ( C57BL/6J × 129/J) F1 genotype.
