Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

The effects of Gastrodia elata on preventing decrepitude and advancing memory are closely associated with its neuroprotective activity. Previous researches proved that G. elata, its active components and preparations played a neuroprotective role by affecting the excitotoxicity, nitric monoxide (NO) system, neuroglia, biomembrane, oxidative neurotoxicity, apoptosis et al. Recent researches also suggest that reducing energy metabolism impairment, anti-inflammatory and immune modulating function may be new research targets of neuroprotective mechanism of G. elata.

OBJECTIVETo investigate the effects of Tianzhi Keli (TZ) on acetylcholine (ACh) and catecholamine levels in striatum of rats with neuromitochondrial impairment, and try to find out the neuroprotective mechanism of TZ.

METHODThe microdialysis and high performance liquid chromatography (HPLC)-post column Immobilized enzyme reactor (IMER)-electrochemical detection (ED) were used to establish a model of mitochondrial energy metabolism impairment which induced by perfusion with sodium azide (NaN3), and measure continuously the effects of TZ on extracellular ACh, choline (Ch) and catecholamine of model rats.

RESULTAfter perfusion with NaN3, ACh, noradrenalin (NE), adrenaline (E), dopamine (DA), 3,4-Dihydroxyphenyl-aletic (DOPAC), and homovanillic acid (HVA) levels were decreased obviously (P < 0.05-0.01), while Ch level was increased distinctly (P < 0.01). Transmitters levels were recovered individually after stop the perfusion with NaN3. TZ can postpone the decrease of ACh and advance the recover of Ch. The effect of TZ coupled with duxil on increasing ACh level is more obviously than effect of TZ or duxil. TZ is also showing a tendency to postpone the decrease of catecholamine and advance its recovery. TZ coupled with duxil can advance the recovery of DOPAC and adjust the metabolic abnormity positively.

CONCLUSIONTZ has effect on protecting impairment of choline neurosystem, which induced by damage of mitochondrion and abnormity of energy metabolism; coupled with duxil have synergistic action. TZ also has tendency to protect the impairment of epinephrine and dopamine neurosystem.

OBJECTIVEStudying the gene expression profiling of different stage hairy root of Salvia miltiorrhiza, in order to find functional genes.

METHODThe contents of second metabolites were determined by HPLC and gene expression profiling was detected by cDNA microarray. cDNA labeled with a fluorescent dye (Cy5 and Cy3-dCTP) was produced by Eberwine's linear RNA amplification method and subsequent enzymatic reaction. The microarrays were scanned with a ScanArray Express scanner using ScanArray 2.0 software and quantified by signal intensities of individual spots from the 16-bit TIFF images using GenePix Pro 4.0. The linear normalization method was used for data analyze. Northern blot was used to test the gene expression results obtained by microarray. Different expressed genes were sequenced and analyzed by gap4 software, and then they were analyzed with BLASTX, BLASTN, GO and KEGG.

RESULTGrowth rate and second metabolites analysis indicated that the stage from 30 d to 45 d was the growth stage, while the stage from 45 d to 60 d was the second metabolites accumulation stage. Accordingly 30 d hairy root was chosen as a reference, which was hybridized with 45 d and 60 d hairy root separately. Total 203 different expressed genes were obtained. Northern blot showed that the result was identical with the microarray result. After sequenced, there were 172 genes clustered into 114 clusters (Unigenes). Among them, 62 unigenes had known functions, 34 unigenes were hypothetical protein, 9 unigenes were homologues with no similarity and 9 unigenes were unidentified protein with low similarity. Total 67 genes were classified into cellular component ontology, molecular function ontology and biological process ontology based on GO analysis. Total 26 genes, which represented 29 metabolic-related enzymes, were located in metabolic maps based on KEGG pathway classification.

CONCLUSIONSeveral important functional genes related to second metabolite synthesis were cloned such as P450 and copalyl diphosphate synthase genes. cDNA microarray was a useful tool for functional genomics of traditional Chinese medicine.

OBJECTIVETo investigate the effect of Tianma Gouteng recipe (TGR) on interfering left ventricular (LV) and aortic hypertrophy and tissue angiotensin II (Ang II) in rats with renovascular hypertension.

METHODThe animal model of renovascular hypertension was used in this experiment. Hypertensive rats were randomly allocated into model group, Enalapril group and TGR group, and the drugs were used for 6 weeks continuously. During this period, the blood pressure of rats was measured every two weeks. After rats were sacrificed, the wet weight, tissue Ang II level of LV and aorta, and the cardiac index were measured.

RESULTOne week after renovascular stenosis, the systolic blood pressure (SPS) of model group was increased by 37.4 mmHg, and 7 weeks after stenosis, the LV and aortic hypertrophy was obvious increased, meanwhile, tissue Ang II of LV and aorta was raised markedly (P < 0.01). Contrasting with the model group, blood pressure was reduced and the morphological index was improved in Enalapril group respectively (P < 0.05 or P < 0.01); the wet weight of LV and aorta were reduced, the morphological index was improved, the rise of Ang II in tissue was suppressed, in TGR group significantly.

CONCLUSIONTGR can attenuate myocardial and aorta hypertrophy induced by renovascular hypertension, and suppress the rise of Ang II in tissue significantly. This suggests that TGR has the effects on interfering LV and aortic hypertrophy by an independent-antihypertensive way.

Objective To observe the influence of long-term treatment with inhaled corticosteroid on biochemical bone indexes and bone mineral density (BMD) in children with asthma. Methods The design was a randomized, paralleled group study with 3 low dose regiments of 100, 200,300 micrograms of budesonide per day in 45 children with asthma aged 5-8 years old for 12 months. Before inhaled corticosteroid therapy and 6th,12th month,clinical effects were observed and lung function(FEV1) was measured; concentration of serum osteocalcin(OST),insulin-like growth factor-1(IGF-1),bony alkaline phosphatase (BALP) and urinary deoxypyridinolin: creatinine (DPD/Cr) were measured; BMD was examined by dual energy X-ray absorptiometry. Results Clinical evaluation was improved and there was significant increase in FEV1 of asthmatic children. The amount of serum OST was slightly higher,yet no significant compared with that of normal control group. There was significant increase of serum BALP in asthmatic children after treatment; there was significant increase in serum IGF-1 of patients group after treatment compared with in normal children at the same age group; there was significant decrease in urinary DPD/Cr after treatment.There was no significant decrease in BMD before and after treatment at the hip (neck of femur , trochanter of femur ,Ward′s triangle),the lumber area of the spine (L2-4) and forearm (ultradis, distal). Conclusion Long-term treatment with low does corticosteroid dose not restrictedly affect bone metabolism and BMD in children with asthma.

OBJECTIVETo analyze the genotype and phenotype correlation in the hemoglobin E (HbE) carriers, and to investigate the effect of HbE on hematological parameters.

METHODSThe capillary electrophoresis was used to screen total 14 141 samples and blood cell analysis was further processed to the HbE carrying samples. Gap-PCR and reverse dot blot hybridization method were used for the detection of Chinese common mutation of α and β thalassemia.

RESULTSThere is a statistical difference in hematological phenotype index (HGB, MCV, MCH, HbE, HbA(2)) between samples of HbE heterozygous (53 samples), HbE homozygous (2 samples), HbE composite α thalassemia (α-thal, 7 samples) and HbE composite β thalassemia (β-thal, 8 samples). Among the four groups, HbE heterozygous \[HGB (122.7 ± 19.99) g/L, MCV (78.65 ± 5.03) fl\] and HbE composite α-thal \[HGB (113.6 ± 22.68) g/L, MCV (73.50 ± 7.73) fl\] had slight effect on hematological parameters, but HbE composite β-thal \[HGB (76.4 ± 12.30) g/L\], MCV (59.23 ± 5.28) fl\] had the heaviest effect on hematological parameters.

CONCLUSIONCo-existence of HbE heterozygous and other type thalassemias showed variation in their hematological phenotype, so patients should be informed of genetics in prenatal diagnosis.
