Objective To inquire into the clinical acceptability of self-developed biochemical test system by comparing the results and bias estimation with the traceable assay system.Methods According to the requests of National Committee for Clinical Laboratory Standards (NCCLS) EP-9A, comparison test and bias estimation for self-developed test system and traceable Roche reference system (HITACHI 7180) were performed by using patient's sera. The self-developed system was set up as axle Y, the traceable Roche assay system as axle X and 1/2 CLIA (%) was used as the acceptable judge standard.Results The relationship of LDL-C between self-developed system and comparison system was inferior, so the results of LDL-C as well as the low values of HDL-C were of low acceptability. The comparabilities of results of ALT, urea, creatinine, TC, ApoA1 and ApoB were acceptable.Conclusion The self-developed test system must compare with traceable assay system, and estimate its clinical acceptability. The regression equation Y=bX+a can be used to correct the bias of test result.

Objective To investigate the effects of puerarin(Pur)on myocardial perfusion and ventricular wall motion in patients withacute coronary syndrome(ACS).Methods Thirty-seven patients with ACS were randomly divided into two groups:conventionaltreatment group(n=17,11 males,range of age:32-80 years,average age:60.9±4.9 years)and Purtreatment group(n=20,12 males,rangeof age:40-76 years.average age:62.7±3.5 years).Patients in the conventional treatment group received standard treatment according tothe current guidelines,while patients in the Pur treatment group received intravenous administration of Pur(500 mg/day)for 10 daysplus conventional treatment.Real-time myocardial contrast echocardiography (RT-MCE) was performed to evaluate the change inmyocardial perfusion index (MPI)and veiltricular wall motion index(VWMI)at admission and 10 days after treatment.Results At10 days after treatment,MPI was significantly higher(P＜0.01)and VWMI significantly lower(P＜0.01)in the Pur group comparingwith those in the conventional group.Conclusions Puerarin might improve myocardial microcirculation perfusion and ventricularwall motion in patients with ACS.

Aim To investigate the role of Wnt/β-cate-nin signaling pathway on the baicalin-induced osteo-genic differentiation in rat bone marrow derived mesen-chymal stem cells ( rBMSC ) . Methods rBMSC was isolated and cultured by adherence screening method. Alkaline phosphatase ( ALP) amount, CFU-FALP and mineralized nodules were compared between each ba-icalin group and vehicle control group at different time points. Real time q-PCR was employed to evaluate the mRNA level of Wnt signaling-related marker ( Wnt10a, GSK-3β,β-catenin and LEF1) after baica-lin treatment. Protein expression of β-catenin and Runx2 was measured by Western blot. Results Ba-icalin significantly increased ALP activities from day 3 to day 7 . The formation of CFU-FALP and mineralized nodules remarkably increased after rBMSC was treated with1, 10, 50 μmol · L-1 baicalin. mRNA levels of Wnt10a, β-catenin, GSK-3β, LEF1and osteocalcin were enhanced significantly in baicalin-treated group compared to control group. Protein expression of β-catenin and Runx2 was also elevated. Conclusion Baicalin ( 0. 1 to 50 μmol · L-1 ) promotes the osteo-genic differentiation and maturation of rBMSC, in which Wnt/β-catenin signaling pathway might be in-volved.

Objective To study the clinical curative effect of Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen for treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). Methods A prospective study was conducted. Forty-six patients with DEACMP admitted into Yidu Central Hospital of Weifang Medical College from January 2012 to January 2014 were randomly divided into observation group (23 cases) and control group (23 cases). The basic treatments of two groups were identical. Based on the basic treatments including hyperbaric oxygen and citicoline sodium injection etc, the observation group was treated with our-self made Tongqiao Huoxue decoction which could be modified in accord to the individual differentiation of syndromes in traditional Chinese medicine (the composition of decoction included Paeoniae Radix Rubra 15 g, Chuanxiong Rhizoma 15 g, Persicae Semen 15 g, Carthami Flos 15 g, Zingiberis Rhizoma Recens 3 pieces, Jujubae Fructus 2 pieces, Moschus 0.5 g, Allium Fistulosum 1 segment). The decoction was administered orally or by nasogastric gavage, one dosage everyday for 1 month, and in the mean time, edaravone intravenously drip 30 mg was given to the observation group twice a day for 14 days. The control group was given hyperbaric oxygen and other conventional treatment for 30 days. The clinical therapeutic effect and adverse reaction were observed after treatment for 30 days. The changes of intelligent level were detected by Hasegawa dementia scale (HDS), and the changes of latency of P300 were measured by electromyologram/evoked potential instrument in two groups before and after treatment. Results The total effective rate in observation group was significantly higher than that in control group [91.3% (21/23) vs. 65.2% (15/23), P < 0.01]. Elevation of creatinine occurred in 1 case, moderate increase in alanine aminotransferase (ALT) appeared in 1 case, and both of them were reduced to normal after treatment in observation group; no adverse reaction occurred in control group. The HDS scores were significantly higher 30 days after treatment than those before treatment in the two groups [control group:13.4±2.8 vs. 6.8±2.3, observation group:20.8±3.4 vs. 6.6±2.5, both P<0.05]. The latency of P300 after treatment was significantly lower in two groups than that before treatment [control group (ms): 355.7±25.7 vs. 385.5±27.8, observation group (ms): 337.3±24.6 vs. 386.8±25.4, both P < 0.05], the change in observation group being more significant [the HDS score: 20.8±3.4 vs. 13.4±2.8, the latency of P300 (ms): 337.3±24.6 vs. 355.7±25.7, both P<0.05]. Conclusion Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen has favorable cognitive effect on patients with DEACMP, thus, it can be used extensively in clinic.

OBJECTIVETo investigate the intervention effect and mechanism of compound Ginkgo biloba (CGB) preparations on nonalcoholic fatty liver disease (NAFLD).

METHODThe C57BL/6 mouse NAFLD model was induced with high fat diets. Since the 2nd week after modeling, the mice were orally administered with 600 and 200 mg x kg(-1) x d(-1) CGB for eight weeks. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHOL) and LPS in serum, as well as pathological changes and expression of tumor necrosis factor-alpha (TNF-alpha) in hepatic tissues were observed. Changes in intestinal tight junction proteins ZO-1, Occludin, Claudin-1 in intestinal tissues were determined under microscopy.

RESULTCompared with the normal group, the model group showed obvious fatty degeneration in rat livers, with notable increase in TNF-alpha expression (P < 0.01), significant increases in ALT, AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05), injury in intestinal tight junction proteins, and remarkable declines in ZO-1, Occludin and Claudin-1 (P < 0.01). Compared with the model group, CGB high and low dose groups showed obvious relieves in fatty degeneration in rat livers and injury in intestinal tight junction proteins, significant reductions in TNF-alpha expression (P < 0.01, P < 0.05) and AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05) and remarkable increases in ZO-1 and Occludin expressions (P < 0.05).

CONCLUSIONCGB can protect intestinal tight junction proteins, reduce intestinal leakage, relieve fatty degeneration and inflammations in livers and prevent NAFLD occurrence and development.
