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.

Objective To investigate the efficacy of MSCs infused intravenously on the regeneration of injured spinal cord and rehabilitation of its neurological function. Methods 32 SD rats, male or female, weight about 300 g for each one. MSCs were separated, cultured and purified in vitro. Surface marker of MSCs, such as CD34, CD45, CD29 and CD90 were detected by flow cytometry. The rat spinal cord injury model was prepared according to the modified Allen method. After exposure of T10 spinal cord, the T10 segment of spinal cord was injuried by a 10 g weight falling down from 5 cm high place upon a round thin copper pad which was placed on the surface of T10 segment of spinal cord. The diameter of the copper pad is 3 mm. There are 24 rats in the injuried group and 8 in the non-injuried group. The injuried group was then divided into experiment group with 14 rats and control group with 10 rats at 24 hours after preparation of models. The rats in the injuried group and non-injuried group were infused with MSCs marked by Brdu through tail vein, and the rats in control group were infused with PBS. The neurological functions of rats were evaluated at 24 hours after injury and 1, 3, 5 weeks post-infusion respectively. At the same time, the immigration, survival and differentiation of MSCs were observed. Results The MSCs were uniformly CD29, CD90 positive and CD34, CD45 negative. In vivo experiment, transplanted MSCs survived and were localized to the injured spinal cord, and a few cells expressed NSE, MAP2 post transplantation 3 to 5 weeks. Significant improvement in functional outcome in rats treated with MSCs transplantation compared to control rats. The score of BBB in the treated group was higher than that in the control group (P

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.

In April 2016,the American Geriatrics Society(AGS)entered into a cooperative agreement with U.S.Department of Transportation.National Highway Traffic Safety Administration (NHTSA) updates and expands the Clinician's Guide to Assessing and Counseling Older Drivers to the 3rd Edition.The main goal of the Guide is to reduce traffic accidents and injuries to older drivers.According to the workflow of evaluation and management provided by Plan for Older Driver Safety(PODS),clinicians can conduct driving strategies after screening,evaluation and result analysis.The evaluation is done based on the Clinical Assessment of Driving Related Skills(CADReS) by a team including physicians,nurse practitioners,physician assistants,pharmacists,occupational therapists,driving rehabilitation specialists,and social workers.The CADReS including a series of assessment tools are used to evaluate in the key areas,such as vision,cognition,and motor/sensory function related to driving.Some measures will be taken based on the evaluation conclusions to help to explore the potential of driving safely for old adults.

The writer observed the sural anastomotic nerve on 276 lower limbs from 138 corpses, including 11 adults and 127 new-borns (84 male, 54 females). It was found that sural anastomotic nerves are present in 219 cases (79.3%) and absent in 57 cases(20.7%). The ways of anastomosis of these nerves fall into the following four types: (1) Type A: The sural anastomotic and lateral sural cutaneous branches arise from peroneal nerve with a common trunk—108 cases (49.7%). (2) Type B: The sural anastomotic nerve is one of the terminal branches of thelateral sural cutaneous nerve—48 cases (21.9%). (3) Type C: The lateral sural cutaneous nerve arises from sural anastomoticnerve—35 cases (16%). (4) Type D: The lateral sural cutaneous and sural anastomotic branches arise separately from the common peroneal nerve—28 cases (12.8%).

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.
