The peak of the brain edema after intracerebral hemorrhage usually begins after 3 to 4 days.A large quantity of hemoglobin releases and degrades during this process,and its degradation products iron ion,bilirubin and carbon monoxide,etc play important roles in the process of cerebral edema.They all involve in the formation Of delayed brain edema after intracerebral hemorrhage.The research of hemoglobin and its degradation products is expected to find out a new way for the treatment of intracerebral hemorrhage.

OBJECTIVE:To establish a preparative separation method for euphol reference substance in Euphorbia pekinensis. METHODS:Parts of petroleum ether extraction from E. pekinensis ethanol extract were separated by silica gel column chromatogra-phy with petroleum ether-ethyl acetate(95∶5-70∶30,V/V)by gradient elution. The enriched fractions of euphol were collected. With the methanol repeated recrystallization,nuclear magnetic resonance spectroscopy(NMR)method,mass spectrometry(MS)meth-od and other spectroscopic methods were used to identify the chemical structures,and thin layer chromatography (TLC),UV, HPLC-UV,HPLC-MS were combined to detect the mass fraction. RESULTS:The mass fraction of euphol reference substance sepa-rated from E. pekinensis was>99%. CONCLUSIONS:The reference substance of euphol acquired by this method meet the relative requirements of the chemical reference substance in the content dertermination of TCM new drug quality standard. It provides chemi-cal reference substance for the quality control of E. pekinensis and prescription preparations containing E. pekinensis and the basic research of effective substances.

OBJECTIVE:To establish mathematical model of liquid volume added of TCM medicinal broth decoction machine to accurately calculate liquid volume added in the process of medicinal herb decocting,so as to guarantee the quality of medicinal herb decocting. METHODS:The water absorption rate of representative TCM decoction piece with high use frequency were deter-mined,and cluster analysis of water absorption rate of TCM decoction piece was conducted according to closely related index as density,size,shape,moisture. TCM decoction piece with similar water absorption rate were bracketed together,so that of single ingredient TCM decoction piece can be estimated by water absorption of representative TCM decoction piece;the quantity of water evaporation and liquid extrusion were determined among different types of decoction machine (powered by electric and gas);ac-cording to the above parameters,mathematical model of liquid volume of TCM medicinal broth prepared by different types of de-coction machine had been established,and validated with TCM formula. RESULTS:Factors that affected the liquid volume added included the water absorption of each ingredient,the quantity of water evaporation and extrusion function. The mathematical model was liquid volume added=water absorption of each ingredient × quality of decoction piece+the quantity of water evaporation+re-quired amount of liquid-parameters of extrusion function×total weight of decoction piece;in validation test,the percentage of the practical amount of liquid to required amount was within ±5%. CONCLUSIONS:Established model can promote the accuracy li-quid volume added and guarantee the quality of TCM decoction when using TCM decoction machine.

Objective Many researches have demonstrated the lowing-intraocular pressure(IOP) effects of bimatoprost and timolol.However,no powerful evidence showed which drug has the better efficacy.This study was to perform a meta-analysis to evaluate the efficacy and tolerability of bimatoprost compared with latanoprost in lowing IOP.MethodsThis was a evidence-based medicine science study.Pertinent studies were identified through searches of PubMed,EMBASE,the Cochrane Liberary Controlled Trials Register and Chinese Biomedicine Database using the terms of timolol,blocardren,temserin,timoptic,bimatoprost,lumigan.The intensive searching by hand and up to October 1,2008 was also designed.ResultsSix randomized and controlled studies enrolling a total of 2 094 patients were included in the meta-analysis and three clinical indexes were analyzed.Bimatoprost was associated with greater decline value from baseline IOP in comparison with timolol(P＜0.01) with a weight mean difference -2.04 at final point(95% CI:-2.44 to -1.64).Numerically greater proportions of bimatoprost patients than timolol patients achieved the target IOP at 3 months(from 3 literature) and ＞6 months(from 2 literature) with a pooled RR of 1.87(95% CI:1.45 to 2.41),1.60(95% CI:1.36 to 1.90) (P＜0.01),respectively.Bimatoprost showed a more frequencies in the adverse effects such as conjunctival hyperemia and eyelash growth than timolol with an RR of 4.18 (95% CI:2.89 to 6.05),9.40 (95% CI:5.62 to 15.71).No obvious drug-related side effect was found from literature analysis included both drugs.Conclusion Searched literature offers grade A of evidences for the comparison clinical evaluation of therapy efficacy between bimatoprost and timolol in lowing IOP.Bimatoprost has a better efficacy in lowering IOP and reaching comparable proportions of patients with target IOP than timolol.Both agents are well tolerated.

Objective To analyze the clinical value of three-dimensional ultrasound in the diagnosis of pelvic floor dysfunction disease.Methods From June 2016 to December 2017,95 cases of female pelvic floor dysfunction disease in the People's Hospital of Dongyang were selected as observation group.And 90 healthy women received physical examination during the same period were selected as control group.Both two groups were subjected to three-dimensional ultrasonography,and the results were analyzed.Results In the observation group,the anteroposterior diameter and area in resting period,anteroposterior diameter and area in tension period,anteroposterior diameter and area in anus period of the anal pelvic diaphragmatic hiatus were (65.58 ± 6.38)cm,(20.01 ± 3.98) cm2,(68.40 ± 5.54) cm,(22.50 ± 3.12) cm2,(60.17 ± 5.55) cm and (19.28 ± 2.52) cm2,respectively,which were significantly higher than those in the control group [(51.84 ± 3.46) cm,(13.93 ± 2.09) cm2,(53.65 ± 4.23) cm,(14.60 ± 2.95) cm2,(48.95 ± 3.48) cm,(13.45 ± 1.76) cm2] (t =18.066,12.903,20.272,13.200,16.369,18.150,P =0.000,0.000,0.000,0.000,0.000,and 0.000).But the pubic rectal muscle thickness of resting period,tension period,anal contraction period in the observation group were (10.28 ± 1.96) cm,(10.63 ± 1.57) cm,and (10.01 ± 1.13) cm,respectively,which were lower than those in the control group [(10.28 ± 1.96)cm,(10.63 ±1.57)cm,(10.35 ±1.49)cm] (t =1.015,1.940,1.741,P =0.311,0.053,0.083).The observation group was asymmetrical,asymmetrical on both sides and interrupted continuously.In the control group,the echo was uniform,bilateral symmetry,without interruption.Conclusion The use of three-dimensional ultrasound in the diagnosis of female pelvic floor dysfunction disease has good clinical value.

Objective To observe the effect of trichostatina to induce mesenchymal stem cells(MSCs) differentiating into cardiomyocyte cells and to explore the potential interference approaches.Methods MSCs were incubated with different concentrations of TSA and different time,then to detecte the histone deacetylase(HDAC) activity;the differentiation of MSCs was observed by phase-contrast mictmcopy;fluorescence immunohistochemistry assessed cardiac troponin T and RT-PCR detected the expression of Nkx-2.5,GATA-4 genes.Results HDAC activity was the lowest when incubated with 300 nmol/L TSA for 24 hours,expression of cTnT of the cells was enhanced after incubation with TSA.The expression of Nkx-2.5,GATA-4 genes was enhanced before interference.ConclusionTSA can promote MSCs to differentiate into cardiomyocyte cells in vitro in an optimized condition.
