OBJECTIVE:To observe the clinical efficacy and safety of different doses of atorvastatin in the treatment of chron-ic subdural hematoma(CSDH). METHODS:One hundred and tweaty-eighie CSDH patients selected from our hospital during Jun. 2013-May 2015 were divided into observation group(n=62)and control group(n=66)in accordance with random number table. Both groups were given conventional treatment of brain cell nutrition. Control group received Atorvastatin tablet 20 mg,po,qd;observation group received Atorvastatin tablet 40 mg,po,qd. Both groups were treated for 6 months. Clinical efficacy,CSS and ADL score,hematoma volume,the levels of serum inflammatory factors (hs-CRP,MMP-9,IL-6,TNF-α) were observed in 2 groups. ADR was recorded during treatment and recurrence rate was also recorded. RESULTS:2 patients withdrew from observa-tion group and 6 from control group. Finally,120 patients met the criteria were included,with 60 cases in each group. Total re-sponse rate of observation group(88.3%)was significantly better than that of control group(73.3%),with statistical significance (P<0.05). After 1,3,6 months of treatment,CSS score,hematoma volume,the serum levels of hs-CRP,MMP-9,IL-6 and TNF-α in 2 groups were significantly decreased,while ADL score was increased significantly;the improvement of above indexes in observation group was significantly better than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). The recurrence rate of control group(13.3%)was significantly higher than that of observation group(3.3%),with statistical significance(P<0.05). CONCLUSIONS:Daily dose of shows ator-vastatin 40 mg better therapeutic efficacy and lower recurrence rate in the treatment of CSDH with good safety.

Objective To explore the diagnostic and prognostic significances of platelet parameters changes in Kawasaki disease(KD).Methods The platelet total(PLT),mean platelet volume(MPV),platelet distribution width(PDW)and plateletcrit(PCT)were measured in 23 cases of KD on acute febrile phase and early recovery phase.It was compared with 33 cases suffered from other febrile diseases during the same period and in similar ages.Each KD child should accept the cardiology ultrasonic examination.Results The level of PLT,PCT increased in KD patients.It was more significant in early recover period than in acute febrile period(P0.05).PLT negatively correlated with MPV,PDW(r=0.358,0.268 Pa0.05).Conclusions The changes of platelet parameter play a very important role in diagnosis of KD.But it still can not be certain that whether the changes can help us estimate the variety of the patients condition and prognosis of KD children.It requires further study.

OBJECTIVETo discuss the hemostasis of the different polarities of Platycladi Cacumen Carbonisatum (PCC) on the blood heat and hemorrhage syndrome rat model induced by dry yeast.
METHODThe SD rats were divided into seven groups. Yunnan Baiyao was taken as the positive control drug. The rats in the control group and model group were fed with CMC-Na for 7 days, and the rats in other groups were fed with corresponding drugs simultaneously. On day 7, the blood heat and hemorrhage syndrome rat model was established. Indexes including the whole blood viscosity, plasma viscosity, thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen content (FIB), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), blood platelet count (PLT), thrombocytocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) and the rate of platelet aggregation induced by ADP were detected. Additionally, the pathological examinations of lungs among each group were compared.
RESULTCompared with the control group, the RBC, HGB and HCT of rats in the model group increased significantly, with distinct increase in high, middle and low whole blood viscosity and plasma viscosity of rats in the model group; TT and APTT were notably prolonged, while PT was notably shortened, with significant increase in FIB content; PLT, PCT, MPV and PDW remarkably increased; Additionally, the rate of platelet aggregation induced by ADP significantly decreased. After ig administration of the ethyl acetate extract of PCC, the low whole blood viscosity and plasma viscosity remarkably decreased; TT and APTT were significantly shortened, with notable reduction in PDW and in FIB content Additionally, the rate of platelet aggregation induced by ADP significantly increased. The injury of lungs was also improved in ethyl acetate extract group. The rate of platelet aggregation induced by ADP of n-butanol extract group notablly increased. Plasma viscosity of water extract group remarkably decreased, with TT being significantly shortened. But the effects of n-butanol extract or water extract were weaker than that of ethyl acetate extract. And the effect of petroleum ether extract was the weakest.
CONCLUSIONEthyl acetate extract is the active part of PCC, showing the effect of hemostasis by reducing the low whole blood and plasma viscosity, improving coagulation function mainly by acting on the endogenous coagulation, and ameliorating the function of platelet aggregation.

Chinese traditional medicine has provided, since ancient times, a basis for health care and medicine to the Chinese nation and for China's national stability. Identification of the constituents responsible for therapeutic and undesired effects of Chinese herbal medicines is a type of key research facilitating the modernization of these medicines. For a complex Chinese herbal medicine, multi-compound pharmacokinetic research is a useful approach to identifying its constituents that are bioavailable (in their unchanged and/or metabolized forms) at loci responsible for the medicine's therapeutic action and to characterizing the compounds' disposition and pharmacokinetics related to the action. In addition, such pharmacokinetic research is also useful for identifying herbal compounds associated with the medicine's adverse effects and drug-drug interaction potential. Over the past decade, great advances have been achieved in the theory, methodology, associated techniques, and their application of such multi-compound pharmacokinetic research, which has become an emerging field in pharmacokinetics. In this perspective, we elaborate on the methodology, technical requirements, and key analytical techniques of multi-compound pharmacokinetic research on Chinese herbal medicines, describe research examples regarding investigation of pharmacokinetics and disposition of a class of bioactive herbal constituents (ginsenosides of

Objective To investigate the effects of low frequency ultrasound (LFU) on the proliferation and apoptosis of smooth muscle cells (SMCs) in rabbits with carotid atherosclerosis(CA).Methods CA models were established in 30 New Zealand rabbits using a high fat diet and air-drying.They were randomly divided into a control group and four LFU groups:group A received 0.5 W/cm~2 LFU for 5 min/d,group B 0.5 W/cm~2 for 10 min/d, group C 1 W/cm~2,5 min/d,and group D 1 W/cm~2,10 min/d.The rabbits' carotid arteries were autopsied after 20 d of the LFU treatment.The expression of PCNA and TUNEL staining were used to explore the proliferation and apopto- sis of SMCs,and the proliferation rates (PRs) and apoptosis rates (ARs) were calculated.Results Compared with the control group,the PRs in groups B,C and D were significantly lower,while the ARs in groups B,C and D were significantly higher.There was no significant difference in ARs or PRs among groups B,C and D.Con- clusion LFU can induce SMC apoptosis and inhibit SMC proliferation in rabbits with CA.
