Objective This study aimed to establish an anatomic basis for the microscopic surgical anatomy of the cavemous sinus via the extended transsphenoidal approach.Methods Simulated surgery via extended transsphenoidal ap-proach was performed on seven adult cadaver heads with red--colored latex injected arteries.The cavernous segment of the ICA and its branch vessels and its relationship with cranial nerve were exposed and its anatomic parameters were measured under microscope.Results The tuberculum sellae,clivus,sellar base,ICA prominence,and optic nerve prominence are the important bone landmarks to define the surgical area.The average of the extent of bone removal of extended transsphe-noidal approach is 37.6 mm(range:28.7 mm~44.0 mm).Conclusions The bone removal from sellar base to the media edge of the foramen rotundum and over the ICA prominence can effectively expose the entire unilateral cavernous sinus.The microscopic cavernous sinus surgery via the extended transsphenoidal approach is an optimal surgical approach for the le-sions that invade the cavernous sinus from sella.

Objective To study the current status of antibiotic usage in Southwest hospital, so as to improve the rationality in applying antibiotic. Methods A total of 1 668 patients in Southwest hospital during Jan 1 to Dec 30, 2003 were investigated in antibiotic usage and the data were sorted and analyzed. Results Antibiotics were administered in 1 247 cases (74.76%), including only 76 cases (6.09%) based on susceptibility test, 39 cases (3.12%) occurred hospital infection. 297 cases (23.81%) abused antibiotics, among which 131 cases (38.04%) were without definite symptoms or with weak signs, 93 cases (31.31%) used more than two kinds of antibiotics, 24 cases (8.08%) frequently changed antibiotic in the treatment, 27 cases (9.09%) inappropriately prolonged administration and 22 cases (7.40%) improperly combined the same antibiotics. Conclusion Irrational utilization of antibiotics exits in clinical work. Therefore, the rational use of antibiotic based on susceptibility tests should be emphasized.

OBJECTIVE:To provide reference for scientific and standardized management of temporary purchased drugs. METHODS:By using ABC analysis method,the data of non-antimicrobial temporary purchased drugs in a hospital in 2014 were analyzed statistically with ABC analysis in terms of quantity,the number of types and departments. Class A drugs were analyzed es-pecially. RESULTS:A total of 152 kinds of drugs were purchased temporarily,including 20 464 boxes,20 kinds of class A drugs, which accounted for 70.56%. Main types were antitumor drugs and nutraceuticals by pharmacology;26 departments temporarily purchased drug,mainly in tumor department and hematology department. CONCLUSIONS:The types of temporary purchased drugs meet the clinical demand in the hospital basically. The necessary type A drugs used frequently can be used as reference of tem-porary drug purchase;the temporary purchased drugs can be managed scientifically and normatively based on ABC analysis.

BACKGROUND:Different types of nerve regulatory factors and glial cells have been reported to exert different roles in the differentiation and maturation of neural stem cells, but culturing neural stem cells in large animals is relatively rarely reported. OBJECTIVE:To explore the way for culturing goat neural stem cells and to detect the outcome after in vitro differentiation. METHODS:The neural stem cellwas separated and cultured from the newborn goat cerebral cortex and the anti-nestin immunocytochemical staining was performed for cellidentification. At the same time, anti-S100 active Schwann cells were gotten from the sciatic nerve. Then in vitro differentiation was preformed and the outcome was detected by the immunocytochemical stain of anti-glial fibril ary acidic protein, anti-microtubule-associated protein 2 and anti-S100. cells without primary antibodies served as controls. Gray values were calculated and compared. RESULTS AND CONCLUSION:The Schwann cells were cultured successful y, which were active to the anti-nestin immunocytochemical staining and anti-S100 staining. After differentiation, the products were active to anti-glial fibril ary acidic protein and anti-microtubule-associated protein 2 immunocytochemical stain, but Abstract BACKGROUND:Different types of nerve regulatory factors and glial cells have been reported to exert different roles in the differentiation and maturation of neural stem cells, but culturing neural stem cells in large animals is relatively rarely reported.
