The budget is an important tool for the control;the elabrate cost accounting is the essential information condition for the control. It is proposed that enhancing the control power must clear responsibility cost, the education quality cost is guaranteed through both increasing income and reducing expenditure.

AIM:To study the role of Rhodiolae rosae in post myocardial infarction angiogenesis and its effect on extracellular regulated kinases(ERK 1/2). METHODS: The experimental myocardial infarction was made by ligation of rat left anterior descending coronary artery,and then divided into Rhodiolae group and saline group.The sham operation group and normal group were also made as control one.On the first,the 4th,the 7th and the(14th) day after the operation,rats were sacrificed and infarcted border tissue or normal tissue were used to test VEGF receptor Ⅱ and CD34 expression level and ERK 1/2 activity level. RESULTS: ERK 1/2 activity level from the first to the 4th day,VEGF receptor Ⅱ and CD34 expression level from the 4th to the 14th day after the operation,were all higher in the Rhodiolae group than that in the saline group. CONCLUSION: Rhodiolae rosae can elevate ERK 1/2 activity which was related to and prior to its angiogenic effect.

Objective To evaluate the effects of Radix Astr agali combined with prednisone and i mmunosuppressant for primary nephrotic syndrome (PNS)in adults and to compare the effects o f Radix Astragali in various prepata tions for PNS.Methods Randomized controlled trials were a pplied for systemic reviews.Electr onic and manual retrieve of Medline,Embase,Cochrane Library,CBMdisc a nd CEBM/CCD and relevant medical jou rnals in China were applied to search the RCTs of Radix Astragali,non -specific treatment,glucocorticoids and i mmunosuppresants for PNS,and the RCTs were analysed with RevMan 4.1.Results There were 14randomized controlled trials with 524cases involved.Meta-analysis showed that Radix Astragali could in crease the therapeutic effect of pre dnisone and immunosuppressant for PNS and re-duce its recurrence.Radix Astragali also had an effect in decreasing 24-hour proteinuria content and the pla sma levels of total cholesterol and albumin.There were no differences between single injection and compound decoction.Asymmetry showed in"Funnel plot"may be related to publication bias,l ow quality of methodology and small -size in sample.Conclusion Radix Astragali and its prescriptio n may become a prospect therapy for PN S and its recurrence and the com-bination of traditional Chinese med icine and western medicine can be more effective for PNS.The dedinite effect of Radix Astragali for PNS will be further con firmed by multiple -center,large -s ample randomized controlled trial.

This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

AIM: To explore the characteristic of relaxation of porcine cornea after LASIKMETHODS: Usual LASIK was performed on fresh porcine corneas with stable intraoculer pressure (IOP) maintained through optic nerve irrigation. The ablation depth on stroma is 30%, 50% and 70% respectively. Then the dumbbell-shaped corneal strip specimens were cut and stored in 20% Human Albumin solution for use (4℃).Sip up the Albumin solution on specimens, and fixed them on homemade jig. Stress relaxation tests were erformed on Tytron250 Dynamics Experiment System. the loading speed was 385mm/min,extending ratewas 1.5, and relaxation time was 1 000s. The data werecollected electronically and automatically.RESULTS: In LASIK procedure, though a single flap-cutting can cause a little reduction of corneal stress relaxation (P＜0.05,P=0.49), the cornea may still remain its property of visco-elasticity. When ablation depth was 30% or more, corneal stress relaxation decreased to almost one half (P＜0.01).The change of corneal stress relaxation degree in vertical meridian specimen was lower than that in horizontal specimen, especially when ablation depth was 70%, and it's statistically significant (P＜0.001). In LASIK operation, the more depth the ablation, the more reduce the stress relaxation degree, and it's easy to cause deformation and creep deformation.CONCLUSION: The changes of the stress relaxation in verticai and longitudinal meridian specimens are similar, and slightly obvious in longitudinal specimen, especially in 70%ablation group.

Embolism index,ratio of central pulmonary involvement,ratio of right ventricle maximum minor axis (RVMMA)to left ventricle maximum minor axis(LVMMA),namely RV:LV,dilation of main pulmonary and/or right pulmonary trunk,and dilation of bronchial arteries in both groups were analyzed comparatively. The correlation factors between CT imaging features and PE clinical severity stratification were explored.The correlation between RV:LV and embolism index of 48 patients was analyzed.Results Pulmonary embolism index(22.0%—85.0%,median 38.0%),ratio of central pulmonary involvement(42.5%),RV:LV (0.90—1.90,median 1.30),dilation of pulmonary artery(14 cases),and dilation of bronchial artery (8 cases)in critical group(21 cases)were higher than those corresponding factors(5%—48%,median 21.5%,31.25%,0.80—1.40,median 1.00,5 eases,and 3 eases)in non-critical group(27 cases) (Z=4.27,X~2=5.40,Z=2.58,X~2=11.45,X~2=4.87,P

The study is aimed to understand the resource and the current situation of the use of Cibotii Rhizoma and provide the basis for protecting and utilization. The method of literature survey, field survey and quality assessment were applied in the study. The results showed that all the Cibotii Rhizoma came from wild resource and was mainly founded in Fujian, Guangxi, Guizhou, Yunnan, Guangdong, Hunan, Jiangxi, Sichuan, Chongqing, Zhejiang, etc. It contains over 5 000 000 kg in the area which total is about 7 000 hm2. The annual output is over 850 000 kg. At present, there is no cultivated resources. Based on the investigation and market sampling analysis from various regions, the results showed that the quality of the collected crude drugs conformed with the regulations of the Chinese pharmacopoeia. However the qualification rate of decoction pieces of Cibotii Rhizoma in market was only 56.4%. At present, the resource of Cibotii Rhizoma could meet the needs of medinal uses. It is important to protect the wild resource which is less and less because of the environmental factors. It also need to make a standard of processing method to ensure the safety, and solve quality problem of the decoction pieces.
