Objective To determine the changes of coagulation indexes of rabbits struck at different levels and sieve the traditional coagulation indexes, such as activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and fibrinogen (FIB). Methods We used correlation analysis to precondition the data to reject indexes, and used stepwise discriminatory analysis to choose indexes and made the diagnosis by multiple linear discrimination analysis. Then, by random sampling we compared the correct diagnostic rate by 4 indexes with that by 3 indexes. Results The correct discrimination rate of blood coagulation function diagnosis in rabbits was up to 87.60% by the four indexes and 96.12% with the three indexes (APTT, PT and TT). The average correct discrimination rate of blood coagulation function diagnosis in 1 000-time random sampling was up to 83.07% by the four indexes and 85.16% by the three indexes. Conclusion Stepwise discriminatory analysis can be used to discriminate hemorrhage from thromboxane. The correct diagnostic rate gets higher when FIB was rejected.

Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

Inorder to make full use of medicinal material resource, the chemical component and pharmacological effects of the stem and leaf have been studied. OBJECTIVE: To observe the preventive effect of total flavones from stem and leaf of scutellaria baicalensis on experimental hyperlipidemia in rats. DESIGN: Randomized controlled trial. SETTING: Institute of Traditional Chinese Medicine, Chengde Medical College MATERIALS: The experiment was conducted in the Institute of Traditional Chinese Medicine, Chengde Medical College from March 1999 to January 2000. Totally 60 male Wistar rats with beginning body mass(200±10)g were provided by Experimental Animal Research Institute, Chinese Academy of Medical Science (Qualification No.01-3008). INTERVENTIONS: Sixty rats were randomly divided into 6 groups:normal control group, high-lipid model group, the groups of 12.5, 25 and 50 mg/kg of total flavonoids (TF group) and clofibrate group (25 mg/kg),with 10 rats in each group. The rats in the normal control group were fed with basic feed. The rats in the high-lipid model group were fed with highlipid feed.Rats in the TF group and clofibrate group were fed synchronously with high-lipid feed and total flavonoids or clofibrate for consecutive 30 days. The change of blood lipid was observed. MAIN OUTCOME MEASURES: The levels of total cholesterol (TC),triglyceride (TG), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) in the serum of all the rats were measured with CL-7200 type automatic biochemistry analytical instrument at the end of the experiment, and the atherosclerosis indexes (AI) were calculated (AI=TC-HDL-C/HDL-C).RESULTS: Totally 60 rats entered the result analysis. ① Level of TC in the serum of rats: The level in the high-lipid model group was significantly higher than that in the normal control group[(5.01 ±1.05,2.33±0.35)mmol/L, (P ＜ 0.01 )]; The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (4.15±1.12, 3.03±0.31,2.98±0.56)mmol/L, there was no significant difference between group of 12.5 mg/kg of TF and model group (t=1.74, P ＞ 0.05), but there was significant difference between groups of 25 mg/kg and 50 mg/kg of TF and model group (t=5.66-5.23, P ＜ 0.01). ②Level of TG in the serum of rats: The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (1.22±0.56)mmol/L,(1.56±0.41)mmol/L,(1.24 ±0.45)mmol/L respectively, compared with model group(2.14±0.74) mmol/L, there was significant difference (t =2.19-3.45, P ＜ 0.05-0.01). ③ LDL-C level of the serum in the rats: The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (2.67 ±0.45) mmol/L, (1.41 ±0.23)mmol/L, (1.29±0.23) mmol/Lrespcrtively,compared with model group[(3.94±0.42)mmol/L, there was significant difference (t=5.77-12.71, P ＜ 0.05-0.01). ④ HDL-C level of the serum in the rats: the level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (0.72±0.23)mmol/L,( 0.91±0.32)mmoL/L,(1.05±0.23)mmoL/L respectively, there was no significant difference between group of 12.5 mg/kg of TF and model group[(0.56±0.21)mmol/L, but there was significant difference between groups of 25 mg/kg and 50 mg/kg of TF and model group (t=2.92-4.38,0.05 ,P ＜ 0.05-0.01).⑤AI: the level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was(2.96 ±1.35), (2.10±0.97), (1.55±0.41)respectively, compared with model group (4.23±0.65) , there was significant difference (t =3.54-9.49 ,P ＜ 0.01). CONCLUSION: TF has significantly inhibitory effect on the increase of TC, TG and LDL-C in the serum of the rats induced by high-lipid feed; it can also increase the level of HDL-C, indicating TF has obviously preventive effect on experimental hyperlipidemia in rats.

Objective To examine the levels of fractional exhaled nitric oxide in bronchial asthma and the cor-relation between fractional exhaled nitric oxide and pulmonary function tests as well as the value of pulmonary function tests in curing the children with bronchial asthma. Methods Seventy - two asthmatic children came from Guiyang Ma-ternal and Child Health Hospital were studied. They were divided into 2 groups:mild - to - moderate asthma group(36 cases)and serious asthma group(36 cases). Fractional exhaled nitric oxide level and the lung function were measured and the correlation analysis was analyzed by SPSS 13. 0 software. Results The fractional exhaled nitric oxide concen-tration of the serious asthma group was significantly higher than that of the mild - to - moderate asthma group[(47 ± 26)ppb vs(29 ± 15)ppb,t = 3. 543,P ﹤ 0. 01],1 - second rate,maximum mid - expiratory flow(MMEF),and peak expiratory flow(PEF)in mild - to - moderate asthma group were significantly higher than those in serious asthma group[(99. 74 ± 9. 81)% vs(87. 17 ± 13. 30)% ,(87. 12 ± 35. 61)% vs(68. 90 ± 30. 88)% ,(99. 97 ± 10. 83)% vs (94. 31 ± 17. 69)% ](P ﹤ 0. 01,0. 05,0. 05). No correlations were found between fractional exhaled nitric oxide level and the lung function parameters,including forced expiratory volume in 1s(FEV1),1 - second rate,MMEF and PEF in the mild - to - moderate asthma group(r = 0. 073,0. 087,0. 242,0. 326,all P ﹥ 0. 05). However the level of fractional exhaled nitric oxide was negatively correlated with the lung function parameters,including FEV1,FEV1 / FVC,MMEF and PEF in serious asthma group(r = - 0. 354,- 0. 573,- 0. 478,- 0. 471,P ﹤ 0. 05,0. 001,0. 005,0. 005),respec-tively.
