Objective: To investigate the current situation of consumption and development tendency of antitumor Chinese herbal injections in Wuhan area. Methods:The analytical method of the defined daily dose ( DDD) recommended by WHO was used to ana-lyze the application of antitumor Chinese herbal injections in 32 hospitals of Wuhan area during the period of 2010-2012. Results:The consumption sum and the DDDs of antitumor Chinese herbal injections were increased year after year, while the daily drug cost ( DDC) was stable in general. The sort of consumption was generally in accordance with the sequence of DDDs. Conclusion:The status quo of antitumor Chinese herbal injections during the period of 2010-2012 is in line with the characteristics of clinical application, indicating the use is rational.

Objective To explore the role of clinical pharmacists in nutrition support therapy in the patients with hyperemesis gravidarum. Methods The clinical pharmacist played a positive role in nutrition support care of a patient with hyperemesis gravidarum by analysising disease characteristics and adverse drug reactions, providing suggestion on the selection of fat emulsion and offering an individualized pharmaceutical care. Results The clinical pharmacist recognized the potential risk in nutrition support plan, took modifications timely, and prevented the occurrence of unfavorable clinical outcomes. Conclusion The participation of clinical pharmacists in nutrition support therapy of the patients with hyperemesis gravidarum is beneficial to improve the efficacy and safety of nutrition support and promote the rational use of drugs.

OBJECTIVE:To determine the contents of chicoric acid in three different pharmaceutical dosage forms by RP-HPLC.METHODS:Samples were determined on VP-ODS C18,with the mobile phase consisted of methanol-1% acetic acid-tetrahydrofuran(33∶62∶5) with flow rate at 1.0 mL?min-1,UV detection wavelength at 327 nm,column temperature at 30 ℃ and sample size at 20 ?L.RESULTS:The linear range of chicoric acid was 0.398 72～3.987 2 ?g(r=0.999 8).The average recoveries of the oral liquid,capsules,and tablets were 99.85%(RSD=0.98%),102.50%(RSD=1.84%),and 100.50%(RSD=1.69%),respectively.CONCLUSION:This method is accurate,reproducible,specific,and suitable for the content determination of chicoric acid.

Objective To investigate the probabilities of brain-derived stem cells from fetal rats differentiating into neurons and astrocytes by velvet antler polypeptide(VAP) in vitro. Methods Neural stem cells from E12-14d rats were cultured for 7 days until neural stem cells (NSCs) aggregations were formed into neurospheres. The neurospheres were cultured at different concentrations of VAP, and immunocytochemistry was used to detect the differentiation of neural stem cells. Results The differentiated cells in 50?g/L VAP group are more than that in control group; the number of NSE positive cells in 50?g/L,100?g/L and 200?g/L groups is more than that in control group.Conclusion Neural stem cells can be successfully induced into neurons by VAP in vitro, which could provide a basis for regeneration of nerve system.;

Objective To investigate the effects of two different dosages of dexmedetomidine on short-latency somatosensory evoked potentials (SLSEP)in intracranial surgery.Methods Forty pa-tients,ASA Ⅰor Ⅱ,aged 20-65 years old,selected for intracranial surgery were randomly divided in-to two groups,20 patients in each group.Bolus dose of 0.5 μg/kg dexmedetomidine was infused within first 10 min and followed by continuous infusion of 0.5 μg·kg-1·h-1 for 10 min in group A;Bolus dose of 1.0 μg/kg dexmedetomidine was infused within first 10 mins and followed by continu-ous infusion of 1.0 μg·kg-1·h-1 for 10 min in group B.SLSEP indications include N20-P25 amplitute and N20 latent period were observed.MAP,HR,N20-P25 amplitute and N20 latent period were re-corded respectively before dexmedetomidine adminstraition (T0 )and 20 mins after dexmedetomidine adminstraition (T1 ).Results Compared with T0 ,MAP and HR at T1 significantly decreased in both groups(P <0.05).N20-P25 amplitude had no statistically significant difference in both groups,while N20 latent period significantly prolonged (P <0.05).Conclusion Both doses of 0.5 μg/kg and 1.0μg/kg dexmedetomidine can significantly prolong the latent period of N20.

Objectives:This study aims to summarize the research progress of multiple-site physician practice to determine further research directions. Methods:Literature on Chinese multiple-site physician practice between 1949 and 2013 was obtained from CNKI, Wan fang database and CQVIP database, the annual volume distribution of se-lected documents was been described and the topics and content of literature cited at least once were summarized through literature content analysis. Results:The volume of literature increased rapidly from 2009, guided by related government policies. Content analysis is insufficient in the research areas of supporting policies, international experi-ences, relevant laws and empirical studies. Suggestions: Further research should focus on multiple-site physician practice policies themselves and supporting policy analysis, international comparisons of multiple-site physician prac-tice systems, studies into relevant laws and regulations and empirical studies based on quantitative methods.

The communication between the students and the teacher was introduced from three aspects of foregone course, communication channel as well as homework and experiment. The individualized teaching mode was described involving expounding common difficulty, assigning and reading over the homework, individualized tutoring after school, on-line responding to the student's question, prompting the student to complete programming and answering questions in evening classes. It's pointed out that the individualized teaching has to take both common knowledge and student difference into considerations. Individulized mode enhances the teaching efficacy greatly.

Objective To analyse the clinical features,imaging characteristics diversity of deep cerebral veins thrombosis (DCVT).Methods From 2004 to 2013,6 patients diagnosed as DCVT were recorded and a retrospective review of the cases were undertaken for the purpose of this analysis.Results Among the 6 patients with DCVT,4 were male and 2 were female,aged from 28 to 69 years old.The disease duration of 4 cases ranged from 2 to 7 days,remnants were 20 days and 3 months respectively.The first symptoms of 4 cases were headache,1 was feeblemindedness,and the other was hemiplegia.The secondary symptoms were disturbance of consciousness,apathy,diplopia and non-infectious fever.Non-contrast computed tomography showed low signal in the bilateral thalamus in four patients,high signal in the transverse sinus and straight sinus in one patient and high signal in torcular in one patient.Abnormal signal was found in bilateral thalamus on magnetic resonance imaging in all patients and some of them had abnormal signal in the mesencephalon or basal ganglia.The patients were definitely diagnosed as DCVT by magnetic resonance venography (MRV) or digital subtraction angiography (DSA).Among them,2 patients were confirmed by brain biopsy.Four patients were followed up with good outcome and 2 were lost to follow-up.Conclusions The clinical manifestations of DCVT are not specific.For acute-onset DCVT patients,the first symptoms are always headache and vomiting,while the main symptoms are declined cognition and slow reaction for chronic-onset ones.Along with the progress,the main symptoms of DCVT are disturbance of consciousness,psychiatric symptoms and intracranial hypertension.Changes in the bilateral thalamus and basal ganglia are especially main characteristics which are easily misdiagnosed as brain tumor according to the images.DCVT can be definitely diagnosed by no signal of deep cerebral veins on MRV or DSA.

Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P
