OBJECTIVETo search for an effective method for treatment of chronic hepatitis B.

METHODSOne hundred and twenty-three cases were randomly divided into a treatment group (n = 63) and a control group (n = 60). The treatment group were treated with injection of Huangqi injectio and Danshen Injectio into Ganshu (BL 18) and Zusanli (ST 36), once every other day; and the control group were treated with oral administration of Gankangning tablet and fufang yiganling tablet. The clinical symptoms, hepatic function, hepatitis B e antigen (HBeAg), hepatitis B virus-desoxyribose nucleic acid (HBV-DNA) were compared between the two groups.

RESULTSThe total effective rate was 93.7% in the treatment group and 76.7% in the control group with significant difference between the two groups (P < 0.01); and the treatment group in hepatic function and the effects of turning negative for HBeAg and HBV-DNA was better than the control group (P < 0.01).

CONCLUSIONAcupoint-injection has a better therapeutic effect on chronic hepatitis B.

OBJECTIVETo explore the relationship of Chinese medicine (CM) syndrome with carotid intima-media thickness (CIMT) and endothelium-dependent vasodilatation function (EDVF) in patients with hypertensive disease (HD) for providing an objective basis of syndrome differentiation in HD patients.

METHODSColor Doppler's ultrasound was used to measure the endothelium-dependent flow-mediated dilation (FMD) of brachial artery and carotid intima-media thickness (CIMT) in 60 HD patients (the HD group) and 30 normal controls (the control group). And the relationship of the outcomes with Chinese medicine syndrome types in patients was analyzed statistically.

RESULTSFMD was lower and CIMT was higher in HD patients of all syndrome types than those in the control group respectively (P<0.01). Comparison between patients of different syndrome types showed that FMD was higher in patients of Gan-fire exuberance type and yin-deficiency and yang-hyperaction type than in those of both yin-yang deficiency type and phlegm-dampness stagnancy type (P<0.01, P<0.05), while CIMT in patients of Gan-fire exuberance type was the lowest in all types, and that in yin-deficiency and yang-hyperaction type was lower than in yin-yang deficiency type (P<0.01).

CONCLUSIONCIMT and FMD may be used as a reference index for CM syndrome differentiation in HD patients.

Objective To investigate the feasibility of the adaptive cardio sequence prospective ECG-gated dual-source CT coronary angiography (CTCA).Methods Thirty one patients underwent prospective ECG-gated dual-source CTCA. The patients were divided into two groups: group A, heart rate ≤ 75 times / minutes, 70% of R-R interval was chose; group B, heart rate> 75 times / minutes, 40% of R-R interval was chose. Two experienced radiologists assessed the image quality of 15 segments of coronary arteries in a double blinded fashion in a four score scale. Student t test was used to compare the image quality between two groups. CT dose index(CTDIvol) and effective dose(ED) were also calculated for both groups. Results 437 segments of coronary arteries in 31 patients were included this analysis, 408 segments (93.4%) had assessable image quality, while 29 segments (6.6%) had non assessable image quality. Of 226 segments in group A, 12 segments (5.3%) had non assessable image quality; however, 17 segments (8.1%) of 211 segments in group B had non assessable image quality. The average score of image quality was 3.57±0.64 in 31 patients. There was no statistical difference for mean image quality of group A (3.65±0.39) and group B (3.41±0.43)( t=1.62,P=0.12 ) . There was a statistical difference for mean image quality for segment 10 on a per segment basis ( t = 3.8 ,P＜0.05). CTDIvol and ED were (18.88±5.04) mGy and (4.31±1.05) mSv, respectively.Conclusion Adaptive cardio sequence prospective ECG-gated dual source CT can acquire assessable image quality of coronary artery with lower radiation dose to the patients, which has the potential to be a routine CTCA technique.

OBJECTIVEAttention deficit hyperactivity disorder (ADHD) is one of the most common behavior disorders in childhood and adolescent. The etiology of ADHD is unknown. The aim of this study was to investigate the relationship between each of the 14 polymorphisms in the five candidate genes and ADHD, and between the combination of some polymorphisms in those genes and ADHD, in attempting to examine whether combinations of genotypes would confer a significant susceptibility to ADHD.

METHODSOne hundred and thirty-nine children with ADHD and one hundred and nineteen normal children were enrolled. Eight single nucleotide polymorphisms (SNP) of three candidate genes were examined with PCR and RFLP techniques. 48 bp VNTR in DRD4 gene was examined with PCR, nondenaturing polyacrylamide gel electrophoresis and silver staining. Five microsatellites (MS) of three candidate genes were examined with genotyping. The relationship between the combinations of 12 polymorphisms and ADHD was examined with logistic regression analysis.

RESULTS1.The frequency of 1065T/1065T genotype and the 1065T allele were significantly higher in ADHD children than that in normal controls (P<0.05). The frequency of -48G/-48G genotype of the A-48G polymorphism of DRD1 gene was significantly lower in ADHD children than that in normal controls (P<0.05). 2. A specific combination of three polymorphisms in the two genes showing an association with ADHD gave a prediction level of 77.5%.

CONCLUSIONSThe T1065G polymorphism in the SNAP-25 may be associated with ADHD. The 1065T/1065T genotype and the 1065T allele may be a risk factor for ADHD. The A-48G polymorphism of DRDI may be associated with ADHD. The -48G/-48G genotype may be a protective factor for ADHD. The specific combination of three sites of SNP in SNAP-25 gene and DRDI gene is found and shows an association with ADHD in 12 polymorphisms of the five candidate genes on glutamatergic/dopaminergic pathway.

BACKGROUNDAppropriate planning and staffing for medical services at large-scale athletic events is essential to provide for a safe and successful competition. There are few well-documented accounts describing the demand for such services. The present study provided the data from the Beijing 2008 Olympics and Paralympics, with a view to provide the guidance for planning future events.

METHODSA total of 22 029 and 8046 patients, who received medical care from a physician at an Olympic or Paralympic medical station, were included. The patient proportion among different personnel, various disease proportions at different kinds of venues, and the disease spectrum at specified venues at the Olympics and Paralympics were analyzed.

RESULTSAt both games, the patient proportion varied by accreditation status. The staff accounted for the largest number of visits at the Olympics (44.83%) and Paralympics (36.95%), with respiratory diseases the most common. Various disease spectrums were discovered at the different kinds of venues. Surgical diseases were the most frequently listed reason for visits, both at competition and non-competition venues, especially during the Paralympics. The sport-related injuries accounted for a majority of the surgical cases during both games. At training venues, ear nose and throat diseases accounted for the greatest number of visits during both games.

CONCLUSIONSDuring both games, people contracted different diseases at different venues. Adequate surgeons should be designated to offer assistance mostly in trauma situations. Appropriate numbers of physicians in respiratory diseases and otorhinolaryngology is of great importance.

The effects of the Smad3- knockout on the hematopoiesis of mouse were investigated in this work. Five pairs of wild type and Smad3- null mice were studied. White blood cell(WBC), red blood cell(RBC) and platelet (PLT) counting of peripheral blood cells were performed with blood obtained from tails. And white blood cells were classified by their morphology. Bone marrow nucleated cells (BMNCs) were counted and classified. The CFU-GM, BFU-E, CFU-GEMM yields were measured in each pair of mice. CFU-S yield of each mouse was measured by injecting bone marrow cells into lethally irradiated 8-10 weeks old wild type female mice. And the pathomorphism of their bone marrows, spleens and livers were observed. As a result, WBC and PLT of Smad3- null mice were significantly higher than those in wild type mice. Smad3- null mice had much more proportion of granulocytes in classification. There wasn't any difference in RBC counting and BFU-E measurement. The yield of CFU-GM increased, while the yields of CFU-GEMM and CFU-S markedly reduced. Bone marrows are actively proliferative, with granulocytosis. The granulocyte/erythrocyte ratio increased. There were no obviously alterative in spleen and liver. Thus Smad3- knockout results in a decreased number of stem and progenitor cells. Moreover hematopoietic differentiation is abnormal with a tendency to forming more granulocytes and platelets. The effect of Smad3 on hematopoiesis is correlative to that of TGF-beta.

OBJECTIVETo investigate the changes in plasma levels of atrial natriuretic peptide (ANP), endothelin-1 (ET-1) and von Willebrand factor (vWF), and their significance among newborns with persistent pulmonary hypertension (PPH).

METHODSSixty-six newborns with PPH (case group) (mild: 26 cases; moderate: 21 cases; severe: 19 cases), as well as 40 newborns without PPH (control group) who were hospitalized in the same period, were enrolled. The control group underwent echocardiography on admission. The case group underwent echocardiography before treatment (with refractory hypoxemia) and after 7 days of treatment for measurement of pulmonary artery systolic pressure (PASP). Meanwhile, plasma levels of ANP, ET-1 and vWF were measured using ELISA.

RESULTSBefore treatment, the case group had significantly higher plasma levels of ANP, ET-1 and vWF than the control group (P<0.05), and these indices increased as PASP rose. After 7 days of treatment, the children with mild or moderate PPH showed normal PASP, and their plasma levels of ANP, ET-1 and vWF were not significantly different from those of control group. The children with severe PPH had significant decreases in all indices, but they were significantly higher than those of the control group. Plasma levels of ANP, ET-1 and vWF were significantly positively correlated with PASP before and after treatment (P<0.01).

CONCLUSIONSChanges in plasma levels of ANP, ET-1 and vWF can reflect PASP in newborns with PPH during treatment. Dynamic monitoring of these indices can help to judge the severity of PPH and guide treatment.
