OBJECTIVETo explore the effect of Chang'an No. I Recipe (CA) on 5-hydroxytryptamine signal system and mRNA expression levels of hippocampal brain derived neurotrophic factor (BDNF) in visceral hypersensitivity model rats with irritable bowel syndrome (IBS).

METHODSIBS visceral hypersensitivity rat models were established by combined chronic restraint stress and forced swimming. Successfully modeled rats were randomly divided into the model group, the Dicetelgroup (27 mg/kg) , the Fluoxetine group (3.6 mg/kg), the high dose CA group (22.6 mg/kg), the medium dose CA group (11.3 mg/kg), and the low dose CA group (5.7 mg/kg) according to body weight, 9 in each group. Besides, a normal control group with 10 rats was set up. Corresponding medication was administered to rats in each treatment group. Equal volume of physiological saline was administered to rats in the model group by gastrogavage. All medication was performed once per day for a total of 14 days. Pain threshold was determined by abdominal withdrawal reflex (AWR). Changes of colon 5-HT levels were determined by immunohistochemical assay. mRNA expression levels of hippocampal 5-hydroxytryptamine 1A receptor (5-HT1a) and BDNF were detected by immunofluorescent RT-PCR.

RESULTSCompared with the normal control group before treatment, pain threshold was obviously lowered in proctectasia rats of each group (P < 0.01). Compared with the normal control group after treatment, pain threshold was obviously lowered in rats of the model group; colon 5-HT levels, mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously elevated (P < 0.01). Compared with the model group, pain threshold was obviously elevated in the Fluoxetine group and all CA groups; colon 5-HT levels were obviously reduced in the Dicetel group, high and medium dose CA groups (P < 0.05, P < 0.01); mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously reduced in each CA group (P < 0.01); mRNA expression levels of hippocampal BDNF were obviously reduced in the Fluoxetine group (P < 0.01).

CONCLUSIONSThe target points of CA were involved in brain and gut. CA could reduce pain threshold of proctectasia rats, down-regulate colon mucosal 5-HT levels, and lower mRNA expression levels of BDNF and 5-HT1a in rat hippocampus.

The aim of the present study was to investigate the effects of adiponectin (APN) on the expression of T-cadherin in cultured Sprague-Dawley (SD) rat cardiomyocytes injured by hypoxia/reoxygenation (H/R). Primary myocardial cells from neonatal rats were obtained by enzymatic digestion. The cells were divided into control group, H/R group and H/R+APN (3, 10, 20 and 30 μg/mL) groups. The H/R group was incubated in anoxic environment (anoxic solution saturated with high concentration N2) for 3 h, and then in the reoxygenation environment (the reoxygenation solution saturated with pure oxygen) for 1 h. The H/R+APN group was pretreated with different concentrations of APN for 24 h prior to the initiation of H/R. The content of lactate dehydrogenase (LDH) was measured by chemistry chromatometry. Cellular apoptosis was analyzed by flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). The expression of T-cadherin was detected by RT-PCR and Western blotting. The results showed that, compared with control group, the apoptotic rate and release of LDH were significantly increased in the H/R group, whereas the expressions of T-cad mRNA and protein were decreased. Pretreating with APN significantly and dose-dependently decreased apoptotic rate and LDH release, and up-regulated T-cad mRNA and protein level in rat neonatal cardiomyocytes under H/R conditions. These results suggest that APN may protect cardiomyocytes against H/R-induced injury by up-regulating H/R-decreased T-cad expression.

In this study, chemistry, biology and pharmacology were combinated to screen pseudoallergenic substances of Shuang-huanglian injection (SHLI) so that to establish a scientific and systematic approach to screen pseudoallergenic substances of traditional Chinese medicine injections. The mouse pseudoallergic reaction models were used to screen the pseudoallergic reaction of SHLI's intermediate extract and the intermediate extract's component or ingredient. Among the three intermediates of Shuanghuanglian injection (extract of Scutellaria baicalensis, extract of Lonicera japonica, extract of Forsythia suspensa) , pseudoallergic action of Forsythia suspensa was the strongest, Forsythia suspesnsa's pseudoallergic reaction mainly associated with the composition with largerchemical polarity. Further it was found that forsythiaside A and arctiin which existed in the the composition with largerchemical polarity caused obvious pseudoallergic reactions. SHLI with removal forsythoside A with the technology of HPLC-MS displayed reduced pseudoallergic reaction and a significant improved safety. This study provided a scientific basis for SHLI process improvements and also offered idea and research foundation for screening pseudoallergenic substances injections in other TCM injections.

OBJECTIVETo analyze the complete remission (CR) rate, disease free survival (DFS) and overall survival (OS) of de novo acute myeloid leukemia (AML) patients treated with HA based three drugs induction chemotherapy and to explore the impact of cytogenetic abnormalities on the prognosis.

METHODSTwo hundred and forty-three untreated de novo AML patients were treated with HA based three drugs induction therapy. CR rate, DFS and OS were calculated. One hundred and eighty-four patients who had karyotype results were divided into four or three groups according to SWOG or MRC criteria respectively. Differences in CR rate, DFS and OS among different groups were evaluated.

RESULTSThe CR rate of all the 243 cases was 77.4%. The median DFS of the 188 CR patients was 28.5 (ranged from 1.0 to 153.0) months, DFS rates at 3 and 5 years were 45.4% and 40.2% respectively. The median OS of the 243 patients was 18.4 (range from 0.5 to 154.0) months. OS rates at 3 and 5 years were 36.9% and 31.4% respectively. According to SWOG criteria, CR rate, median DFS and OS were 97.8%, 87.4 months and 89.0 months for the favorable group; 81.9%, 17.6 months and 22.3 months for the intermediate group; 61.5%, 9 months and 11.5 months for the adverse group; and 79.3%, 29.0 months, 19.9 months for the unknown group, respectively. The differences among the four groups were statistically significant (P < 0.001). According to MRC criteria, CR rate, median DFS and OS were 96.1%, 79.9 months, 72.2 months for the favorable group; 80%, 17.6 months, 19.7 months for the intermediate group; and 43.8%, 16.5 months, 12 months for the adverse group, respectively. The differences among the three groups were statistically significant excepting for DFS between intermediate and adverse groups.

CONCLUSIONSHA based triple-drug induction regimens are highly effective in obtaining higher CR rate and longer survival time. Cytogenetics is the important prognostic factor for AML patients and SWOG karyotype subtyping criteria is more appropriate than that of MRC, the differences among the three groups being statistically significant.

Restriction by hardware caused the very low projection number at a single phase for 4-dimensional cone beam (4D-CBCT) CT imaging, and reconstruction using conventional reconstruction algorithms is thus constrained by serious streak artifacts and noises. To address this problem, we propose an approach to reconstructing 4D-CBCT images with multi-phase projections based on the assumption that the image at one phase can be viewed as the motion-compensated image at another phase. Specifically, we formulated a cost function using multi-phase projections to construct the fidelity term and the TV regularization method. For fidelity term construction, the projection data of the current phase and those at other phases were jointly used by reformulating the imaging model. The Gradient-Projection-Barzilai-Line search (GPBL) method was used to optimize the complex cost function. Physical phantom and patient data results showed that the proposed approach could effectively reduce the noise and artifacts, and the introduction of additional temporal correlation did not introduce new artifacts or motion blur.
