The material of this paper comes from a real consolidation case of the radiography department of a hospital, which succeeds in sharing several automatic processors through layer 3 switching.

The use of five or more drugs (polypharmacy) is common problem in the elderly,and need to attach importance.Optimization of drug treatment is a major part of medication in older adults,and also is a challenge to clinical physician.Beers Criteria provided by American Geriatrics Society (AGS) is a strong guarantee for improving medication safety in older adults

To analyze the problems in teaching regulation of gene expression in biochemistry and investigate the teaching method which can improve the teaching of the contents.

AIM: To analyse the variety of the alkaloid and volatile oil from Herba Ephedrae after mix-fring with honey. METHODS: The volatile oil was analysed by GC-MS and the total alkaloids were determined by method of Chp. RESULTS: The volatile oil changed distinctly. The contents of Isolineole、p-Cymene、D-limonene、Evcalyptol、?-Terpinen increased evidently, but the contents of Benzaldehyde、Tetramethylpyrazine、p-Vinylanisole、?-Terpineol、?-Terpineol decreased and the contents of the total alkaloids decrease as well. CONCLUSION: The study provides a new experimental basis for the process theory of Herba Ephedrae.

Palliative and hospice care for patients suffering severe or end-stage illness with projected short life expectancy.Such services aim to improve patients' quality of life through prognosticating,prevention and treatment of their ailment.The main components include evaluation and treatment of symptoms,pain control,family care,alleviating and treating patients' psychological burden and depression,and offering comfort and dignity.Hospice and palliative care are different from euthanasia,because they neither hasten nor delay the dying process.Instead,they focus on patients'physical and psychological needs and helping patients to maintain their independence and make their own choice.As a new medical subspecialty,palliative and hospice care are considered one of the important frontier in modern medicine.They employ a multi-disciplinary team approach,and the team members require special skill sets including those in communication and symptom management.

Objective To observe the expression of matrix metalloproteinase(MMP-2, MMP-9 and vascular endothelial growth factor (VEGF) in retinoblastoma (RB) and its relationship with the differentiation and optic nerve infiltration of RB. Methods Forty paraffin specimens of pathological confirmed RB were studied. They were divided into differentiated group (15 cases) and undifferentiated group (25 cases) , optic nerve infiltration group( 13 cases) and without optic nerve infiltration group(27cases). The expression of MMP-2, MMP-9 and VEGF were detected by immunohistochemistry, their relationships with the differentiation and optic nerve infiltration were also analyzed. Results The positive rate of MMP-2, MMP-9 and VEGF expression in 40 RB cases were 52.5%, 57.5% and 72.5%respectively. The expression of MMP-2, MMP-9 and VEGF in the undifferentiated group were significantly higher than those in the differentiated group (χ2= 9. 037, 9. 253, 8. 095;P＜0. 05). The expression ofMMP-2, MMP-9 and VEGF in RB with optic nerve infiltration group were significantly higher than those in RB without optic nerve infiltration group (χ2=11.045,10. 243, 8. 956;P＜0. 05). The expression of MMP-2,MMP-9 had a positive correlation with the expression of VEGF in RB (r= 0. 126, 0. 314;P ＜ 0. 05).Conclusions MMP-2, MMP-9 and VEGF expressed in RB tumor tissues. The expression of MMP-2,MMP-9 has a positive correlation with the expression of VEGF. The levels of MMP-2, MMP-9 and VEGF expression are related to optic nerve infiltration of RB cells.

A 64-year old man was admitted on July 2011 with masses both in liver and right kidney.After PET-CT and blood test examination,dual primary advanced cancers were speculated to be co-existed in this patient,which having poor prognosis.By evaluation with comprehensive geriatric assessment,the patient also had hypertension,diabetes and atherosclerosis,liver and renal insufficiency.After multidisciplinary consultation and detailed discussion with the patient,the decision of no surgery and just keep the follow-up was made.The patient has been followed up for 18 months and the functional evaluation is the same as before.It is very important to evaluate the risk/benefit equation and improve the standard of care,and make the decision as patient centered rather than disease-centered in the elderly patients.

Chinese Caterpillar Fungus (CCF) is one of the rare Chinese traditional drugs. As the resource is reducing sharply, the price is rising higher and higher, and there have been much more adulterants in the markets, but until now we don't have a scientific and accurate research on the identification study for this drug. On the basis of resource investigation, during the study of the samples collected by ourselves and the specimens stored in the museum, using the macroscopic and microscopic methods, referring to the literatures of entomology, emphasizing on the characteristics of polypide part, we have studied this species in detail of the macroscopic characters such as the insertion position of the stroma part, the annulations and segments of the caterpillar, the abdominal leg, the pinaculum, and the microscopic characters of the body wall; firstly added the microscopic character of the crotchets on the planta of abdominal leg. The result turned out that the characters which we have studied are regular and stable, and it have laid the foundation for the powder products and patent medicines which have used the crude drug of CCF.

Objective To assess the changes of left ventricular function after off-pump coronary artery bypass (OPCAB) using Tei index. Methods Fourty-six patients of coronary artery disease, who had accepted OPCAB, were enrolled. Left ventricular ejection fraction(LVEF), E/A ratio at mitrial orifice(E/A), E deceleration time(EDT), isovolumic relaxation time(IVRT), ratio of systolic wave to diastolic wave of pulmonary vein flow(S/D) and Tei index were measured by transthoracic echocardiography before, immediate, 1 week, 1 month, 3 months and 6 months after OPCAB. Results Tei index decreased gradually as time went on after OPCAB and the differences were significant between different times(P
