Objective To characterize the systolic torsion in dilated cardiomyopathy (DCM) by velocity vector imaging(VVI).Methods Eighty-seven subjects were studied using VVI:27 patients with DCM and 60 healthy control subjects.Left ventricular short-axis acoustic images were acquired at base and apex levels.The rotation angle and rotation velocity of endocardium and epicardium were measured.Results LVEF of DCM group was significantly lower than that of control group ( P＜0.01).The basal and apical rotation angle, rotation velocity were significantly lower in DCM group.The endocardial and epicardial rotation angle, rotation velocity were also significantly lower in DCM group than those in control group (P＜0.01).Conclusions VVI is a rapid and noninvasive tool to quantitatively assess cardiac torsional deformation in DCM patients,which providing another useful modality for evaluating cardiac function.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo search for an effective therapy for chronic hepatitis with splenomegaly.

METHODSFive hundred and seventy eight cases of chronic hepatitis with splenomegaly were randomly divided into a treatment group (n=292) and a control group (n=286). The two groups were treated with intravenous drip of hepatocyte growth-promoting factors and Danshen Injectio, with TCM iontophoresis added to the treatment group, once daily, 20 sessions constituting one course. After one course, their therapeutic effects were observed.

RESULTSBoth the cured rate and the effective rate on splenomegaly were 66.1% and 98.6% in the treatment group, which were higher than 18.2% and 76.2% in the control group. The treatment group in the therapeutic effect in improvement of liver function and attenuation of the spleen and remission of hyperfunction of the spleen was better than the control group (P < 0.05).

CONCLUSIONTCM iontophoresis has obvious therapeutic effect on chronic hepatitis with splenomegaly.

Objective To study the effects of Chinese herbs Yiyanheji on intestinal mucosa barrier in rats with SAP.Methods Animal models of SAP were induced by retrograde injection of 5% sodium taurocholate (0.1ml/100g) into the common biliopancreatic duct.90 healthy Wistar rats weighing (250?30)g were randomly divided into 3 groups:sham operation group (SO,n=30),SAP group (SAP,n=30) and Chinese herbs Yiyanheji treated group(SAP+YH,n=30).Treated group was treated with Yiyanheji after operation.The SAP group was treated with physiological saline.Three groups of rats were killed at 72 hours after operation or treatment.Bacterial cultures were performed in all animals.The changes of terminal ileum' tissue were observed by optical electron mi- croscopy.The data of test were analyzed by statistic software.Results The incidence of bacterial translocation was 22.5% in Yiyanheji treated group,and it was lower than that in SAP group which was 90.0 %.The difference was significant(P

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.

OBJECTIVETo evaluate clinical therapeutic effect and the safety of pricking blood therapy combined with ultraviolet irradiation for treatment of acute herpes zoster.

METHODSOne hundred and thirty cases were randomly divided into an observation group and a control group, 65 cases in each group. The observation group was treated with pricking blood therapy combined with ultraviolet irradiation. Firstly, the affected parts were heavily taped with a plum-blossom needle and then cupping. After the cup was removed, with the body surface-dividing field method, ultraviolet irradiation was given at the skin injury area and the nerve root area corresponding to paraspinal vertebra, and the control group was treated with Aciclovir and other western medicine. Seven days constituted one course. Their therapeutic effects and adverse reactions were observed.

RESULTSAfter treatment of 7 days, the cured rate of 76.9% and the total effective rate of 90.8% in the observation group were significantly higher than 38.5% and 66.2% in the control group, respectively (both P < 0.01); the incidence rate of post herpetic neuralgia of 3.1% in the observation group was significantly lower than 12.3% in the control group (P < 0.05); after treatment, the scores for pain, rash and sleep decreased significantly in the two groups (all P < 0.01), more significantly decreased in the observation group than in the control group (P < 0.01 or P < 0.05); the pain-relieving time, herpes-stopping time, scab-forming time and the cured time in the cured patients of the observation group were significantly shorter than those in the control group (P < 0.01 or P < 0.05).

CONCLUSIONThe pricking blood therapy combined with ultraviolet irradiation has rapid therapeutic effect, effectively shortens duration of illness, decreases the incidence rate of post herpetic neuralgia and it is a safe remedy for treatment of herpes zoster.
