Objective: To establish the GC-MS fingerprints of volatile oil in crude, water-processed, and vinegar-processed Cyperi Rhizoma, and to capture the whole scope of the chemical constituents changing. Methods: The fingerprints of volatile oil in crude, water-processed, and vinegar-processed Cyperi Rhizoma were established by GC-MS. And the data were analyzed by chromatographic fingerprint similarity evaluation software for Chinese materia medica (Version A). Results: The similarities of each group were good, which indicated that the technology was stable and feasible. The crude group gained 52 common peaks, 28 as the water-processed group, and 53 as the vinegar-processed group. Meanwhile, 46 chemical components among the peaks above were identified in total. Comparing with the three groups, the kinds and contents of many components in each group were changed after processing. With the crude group as reference, the differences between the water-processed group and vinegar-processed group were contrastively analyzed before and after processing, and the Cyperi Rhizoma processed with vinegar could remain the chemical constitutions in its volatile oil better. Conclusion: Using vinegar as processing accessory is scientific and reasonable. Vinegar could play a role in protecting the compounds of volatile oil in Cyperi Rhizoma steadily.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

OBJECTIVETo observe the intervention and mechanism of Qushi Huayu Recipe (QHR) on gene expression profiles in high lipid diet induced fatty liver rats.

METHODSFatty liver model was prepared in 20 male SD rats using single high fat diet (88% common forage +2% cholesterol +10% lard). Four weeks after modeling they were divided into the model group and the QHR group according to random digit table, 10 in each group. QHR (at 0. 93 g crude drug/100 g body weight) and distilled water was respectively to rats in the QHR group and the model group by gastrogavage while modeling, once per day. Meanwhile, 10 SD male rats were recruited in a normal group, administered with equal volume of distilled water by gastrogavage. At the end of week 8 all rats were sacrificed, and blood and livers were collected for subsequent analysis. Contents of liver triglyceride (TG) and free fatty acid (FFA) , activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using biochemical assay. Pathological changes of liver tissue were observed using H&E and oil red O stain. Liver gene expressions were detected by Affymetrix gene expression profiles. Differentially expressed genes were compared between the QHR group and the model group, functions of differentially expressed genes and signal pathways involved analyzed. Ten differentially expressed genes involved in glycolipid metabolism with fold change more than 2 were selected for verification by real-time PCR.

RESULTS(1) Compared with the normal group, contents of liver TG and FFA, and serum activities of ALT and AST obviously increased in the model group (P <0. 01). Compared with the model group, contents of liver TG and FFA, and activities of ALT and AST obviously decreased in the QHR group (P <0. 05, P <0. 01). QHR could reduce high fat induced fatty degeneration of liver cells , alleviate inflammation, and improve pathological changes of liver tissue. (2) Compared with the model group, there were 80 differentially expressed genes (with fold change > 2, P < 0.05) with clear functions and appointed gene names, including 44 up-regulated and 36 down-regulated genes. Eighty genes were involved in 27 signal pathways with statistical difference, including glycerolipid metabolism, adipocytokine signaling pathway, insulin signal pathway, drug metabolism signal pathway, etc (P < 0.05). (3) RT-PCR results of 10 glycolipids metabolism regulating genes such as Gk, Scd1, Gpat2, G6pc, Irs1, and so on showed that all RT-PCR genes were completely coincide with up-regulated or down-regulated tendency in results of gene chips. 80% genes had approximate fold change.

CONCLUSIONQHR could regulate gene expressions related to fat metabolism, carbohydrate metabolism, anti-lipid peroxidation, and drug metabolism in high fat diet induced fatty liver rats, and its comprehensive pharmacological actions could be manifested.

OBJECTIVETo observe the thoracic aorta features in patients with bicuspid aortic valve (BAV) with echocardiography.

METHODSWe retrospectively analyzed the echocardiographic features and clinical manifestations in 273 patients with BAV detected from 1991-04 to 2006-02.

RESULTS(1) Aortic dimensions of the anulus, the sinuses of valsalva, the sinotubular junction, the ascending aorta at the level of its largest diameter of 31 patients with functionally normal BAV were significantly increased compared that in control subjects (P < 0.01 to P < 0.001) while the dimension of the descending aorta posterior to the left atrium was similar between the two groups (P > 0.05). (2) There is no relation between the vulval positions of BAV and aortic dimensions (P > 0.05). (3) The dimensions of the annulus as well as the sinuses of valsalva were negatively related to the aortic valve gradient, and the dimension of the annulus, the sinuses of valsalva and sinotubular junction were positively related to the degree of aortic regurgitation in 273 patients with BAV (all P < 0.05).

CONCLUSIONOur results show there is a hemodynamic independent thoracic aortic dilation in patients with functionally normal BAV. Gradient and aortic regurgitation are related to the dimension of the annulus, the sinuses of valsalva and sinotubular junction in patients with BAV.

OBJECTIVETo sum up the experience of performing ascending aorta replacement combined triple-branched stent graft implantation for acute Stanford type A aortic dissection.

METHODSFrom January 2010 to December 2010, 14 patients with acute Stanford type A aortic dissection underwent the procedure of performing ascending aorta replacement combined triple-branched stent graft implantation. Right axillary artery cannulation was used for cardiopulmonary bypass and selected cerebral perfusion. When the body temperature drops below 18°C, the ascending aorta was transected near the base of the innominate artery. From the incision, the triple-branched stent graft was implanted into the true lumen of the arch, descending aorta and the aorta bifurcation vessel. The transected stump of the ascending aorta was anastomosis to the proximal of the branched blood vessel prosthesis.

RESULTSCardiopulmonary bypass time was (186 ± 38) min, cross clamp time was (101 ± 27) min, and average selective cerebral perfusion and lower body arrest time was (39 ± 11) min. The in-hospital mortality was zero. One patient of transient postoperative neurologic dysfunction, one of acute renal failure, one of transient limbs disturbance, one of secondary thoracotomy operation, one of gastrointestinal hemorrhage and one of postoperative chylothorax were observed. CT angiography rechecked showed the position of the vascular stent were satisfactory and the blood flow of arterial branches stents were lucid. The false lumen of the aortic arch and descending aorta closed with thrombus or shrinked.

CONCLUSIONSThe patients required aortic arch to be reconstructed which had no main tearing of intima in the arch may be best candidates for this technique. Open triple-branched stent graft placement combined ascending aorta replacement is an effective means for aortic arch reconstruction in acute Stanford type A aortic dissection.

OBJECTIVETo measure the expression of lymphocyte function-associated antigen-3 (CD58) in childhood B-lineage acute lymphoblastic leukemia (B-ALL) and to explore the feasibility of CD58 as an indicator for minimal residual disease (MRD) detection in childhood B-ALL.

METHODSEighty-seven children diagnosed with B-ALL between January 2014 and September 2014 were enrolled, and 20 hospitalized children who had no tumor or blood disease and had normal bone marrow cell morphology served as the control group. The expression features of CD58 in bone marrow samples from the two groups (at diagnosis, on day 15 of induction chemotherapy) were analyzed by four-color flow cytometry (FCM). Quantitative real-time polymerase chain reaction (qRT-PCR) and FCM were used to detect MRD in B-ALL patients on day 33 of induction chemotherapy.

RESULTSThe mean fluorescence intensity of CD58 expression in the 87 B-ALL cases (91±33) was significantly higher than that in the 20 controls (14±6) (P<0.01); CD58 was over-expressed in 44 of the B-ALL cases. In the B-ALL children, the expression of CD58 on day 15 of induction chemotherapy (105±22) was not significantly different from that at diagnosis (107±26) (P>0.05). In the 44 B-ALL patients with CD58 over-expression, FCM showed 9 MRD(+) cases and 35 MRD(-) cases, while qRT-PCR showed 11 MRD(+) cases and 33 MRD(-) cases; 42 cases (95%) showed consistent results of the two tests, so there was no significant difference between the two methods in detecting MRD (P>0.05).

CONCLUSIONSCD58 is over-expressed and stable in children with B-ALL, and it can be considered as an indicator for MRD detection in childhood B-ALL.

BACKGROUNDMyocyte apoptosis is considered to be the major causative factor of left ventricular (LV) remodeling following myocardial infarction (MI). We previously reported that 3', 4'-dihydroxyflavonol (DiOHF), was able to suppress oxidative stress and preserve the expression of endothelial nitric oxide synthase during myocardial reperfusion injury, which may benefit the reduction of myocyte apoptosis. We therefore aimed to evaluate the potential actions of DiOHF against myocyte apoptosis and post-infarction LV remodeling in this study.

METHODSFollowing experimental MI, surgical instrumented goats were randomly assigned into vehicle and DiOHF (2 mg/kg; i.v., daily) groups to receive 4 weeks of reperfusion with corresponding treatments. LV pressure recordings and echocardiogram were performed at baseline, 2 and 4 weeks of reperfusion. Myocardial tissues were collected in the end to determine infarct size and apoptosis related assays.

RESULTSLV end-diastolic volume and diameter were significantly increased 4 weeks after MI in the vehicle group, accompanied by reduced posterior wall thickness, septal thickness and LV mass, whereas those changes were markedly prevented by DiOHF treatment. Similarly, significantly reduced infarct size was found in DiOHF group as compared to vehicle group, and DiOHF dramatically inhibited the increase in LV end-diastolic pressure and the reductions in ejection fraction, fraction shortening and dP/dt(max). Moreover, DiOHF treatment significantly reduced the extent of myocyte apoptosis detected by TUNEL assay, enhanced the protein expression of caspase-3, Fas, Bax and cytochrome c in the non-infarcted myocardium in comparison to vehicle.

CONCLUSIONSDaily DiOHF treatment during the reperfusion period after MI in the ovine hearts markedly reduced the magnitude of post-infarction LV remodeling through the inhibition of myocyte apoptosis in the remote non-infarcted myocardium.
