The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

AIM:To investigate the effect of pretreatment of stem cell factor(SCF) and granulocyte colony-stimulating factor(G-CSF) on the proliferation and the differentiation of mesenchymal stem cells(MSCs) into cardiomyogenic cells.METHODS:The MSCs,isolated primarily from bone marrow,and purified by passage culture,were obtained from the adult rats of four groups:the rats were pretreated by 5 daily injections of SCF;the rats were pretreated with G-CSF;the rats were pretreated with SCF and G-CSF;the rats were treated without any intervention.The 4th passage of MSCs was labeled by DAPI and cellular cycle analysis was conducted by flow cytometry before co-culture.The neonatal rat cardiomyocytes cultured for 3 days were co-cultured with DAPI-MSCs.The percentage of the differentiation of MSCs into cardiomyogenic cells during the five co-culture days was analyzed.The morphologic changes of MSCs and the proteins expression of cardiac myosin heavy chain(MHC) and troponin T(TnT) were recorded respectively with digital microscope camera system and immunofluorescence technique.The percentage of the differentiation of MSCs into cardiomyogenic cells was also calculated.RESULTS:The percentage of MSCs in G0/G1 phase in SCF/G-CSF group was significantly lower than that in SCF group,G-CSF group and the control group.The percentage of MHC protein-positive MSCs in SCF/G-CSF group was markedly higher than that in SCF group,G-CSF group and the control group,and that in SCF group and G-CSF group was significantly higher than control group.The percentage of TnT protein-positive MSCs in SCF/G-CSF group,SCF group and G-CSF group was significantly higher than that in control group.CONCLUSION:SCF and G-CSF show the ability to stimulate the proliferation of MSCs and induce MSCs to differentiate into cardiomyocytes.The combination of using SCF and G-CSF is more effective than using only SCF or G-CSF.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective To explore the microRNA expression changes and related characteristics and analyze the corresponding miRNA target genes and their bioinformatics in colorectal cancer with liver metastasis.Methods The fresh specimens of primary CRC were collected in 10 patients during operation,with liver metastasis or without.The miRNA expression levels were compared by miRNA microarray between two groups.Then,target genes were identified using target prediction algorithms.The liver metastasis related miRNA-target networks and gene ontology (GO) bioinformatics analysis were further performed.Results A total of six dysregulated miRNAs were identified in colorectal cancer liver metastasis comparing with no metastasis,including 3 up-regulated miRNAs (miR-224,miR-1236,miR-622) and 3 downregulated miRNAs (miR-155,miR-342-5p,miR-363).miR-224 with most significantly up-regulation played regulation role not only with corresponding target-genes but also downstream genes.Conclusions As a core of the regulation networks,miR-224 can regulate the related gene functional groups simultaneously and asynchronously.It further implements the post-transcriptional regulation and plays a vital role in liver metastasis of colorectal cancer.

OBJECTIVETo observe the improvements in constipation differentiated as intestine system syndrome and lung system syndrome treated with electroacupuncture (EA) and explore their correlation.

METHODSSeventy cases of severe functional constipation were randomized into an EA group and a pseudo-EA group, 35 cases in each one. In the EA group, the needles were inserted deeply at Tianshu (ST 25) and Fujie (SP 14) on bilateral sides, and directly went to parietal peritoneum. EA was attached to the needles, dense-disperse wave, 2 Hz/15 Hz, and 0.1 to 1.0 mA. The perpendicular insertion was done at Shangjuxu (ST 37), 25 mm in depth. After qi arrival, the needle was lifted, thrusted and rotated once every 10 min, for 3 times totally. The needles were retained for 30 min. In the pseudo-EA group, the pseudo-points lateral to Tianshu (ST 25), Fujie (SP 14) and Shangjuxu (ST 37) on bilateral sides were punctured shallowly. The electric stimulation was pretended to connect but with the electric wire cutting off. The needles were retained for 30 min. The treatment was given 5 times weekly in the first two weeks and 3 times weekly in the later 6 weeks. Totally, 28 treatments were required. TCM intestine and lung syndrome scale was used for evaluation. The changes in TCM syndromes were observed before and after treatment in the patients of the two groups.

RESULTSThe total score of intestine and lung syndrome and the score of individual syndrome were all reduced after treatment as compared with those before treatment in the two groups (both P<0.01). The improvements of the EA group in the total score of intestine system syndrome, the scores of large. intestine syndrome and stomach syndrome, the total score of lung system syndrome and the score of lung dysfunction in dispersing and descending syndrome were superior to those of the pseudo-EA group (P<0.01, P<0.05). The differences in the scores of lung qi deficiency syndrome and throat syndrome were not significant between the two groups (all P>0.05). Simultaneously, the very strong positive correlation (P<0.01) and positive linear correlation (P<0.01) were presented in the total score of intestine and lung syndrome of the two groups.

CONCLUSIONEA obviously improves in intestine system syndrome (including large intestine syndrome and stomach syndrome), as well as lung system syndrome (lung dysfunction in dispersing and descending) in the treatment of constipation. But the improvements are not apparent in the treatment of lung qi deficiency and throat disorder. Additionally, the obvious correlation is displayed in the improvements in intestine and lung syndrome.
