Five inner ears were removed from five rabbits under aneasthesia. The hard, thick bones of outer and middle ears were trimmed off, and the auditory ossicles were taken away. The cochleae were fixed with 2％ glutaraldehyde in phosphate buffer for eight hours, then they were decalcified in 10％ EDTA-2Na solution for ten days, and the softened shells of the cochleae were stripped off, and post-fixed in 1％ OsO_4 for an hour, dried at critical point, coated with gold, and observed under SEM.The rabbit cochlea shows two and a half turns, the modiolus is about 3.5mm high, and the organ of Corti lies on the basilar membrane of the spiral lamina. The outer hair cells usually form three parallel rows on the middle and basal turns but occasionally four rows on the top half turn. The inner hair cells form only a single row. Every bunch of the outer hairs consists of about 93-114 stereocilia which together show a "W" shape. Every bunch of inner hairs has about 50 cilia which together show an arch shape. The cilia on the top turn are longer than those on the base. The length and width of the inner and outer hair cells and four other kinds of cells were measured according to photos, and the numbers of these kinds of cells were estimated.Other three cochleae fixed at the time of 1, 2 or 4 hours after death were also observed. In the cochlea fixed four hours after death, the majority of the auditory hairs were found fallen down, which means the fixation of cochlea should be carried out within less than four hours after death.Some of the structural similarities and differences of cochleae among rabbit,human being and guinea pig were also compared in this paper.

Neuroblastoma (NB)is a common malignant solid tumor in childhood,which has various clinical manifestations.It is difficult to diagnose and to prone to early metastasis.It is one of the main diseases causing death in childhood.The treatment of children with high-risk NB is still very challenging.At present,the treatments of NB mainly concentrated in the surgery,chemotherapy,radiation therapy and transplantation technology,etc.In recent years,more studies focus on targeted therapy and molecular biology (genetics) treatment.Targeted therapy is targeted to different specific loci of tumor,so as to kill tumor cells and reduce the impact on the normal tissue,which supplies more safe and effective treatments for children with NB.

Objectives: To investigate the effects of the extract mixture of alfalfa and perilla on lowering serum lipid, protecting liver and aortic wall in rats. Methods: Sixty SD rats were divided into six groups and were fed different diet. After seven or fourteen days, the rats were put to death and measured for serum lipids, cholesterol content of liver and aortic wall, and pathological change of the tissue. Results: There was a significant increase of serum TC, LDL-C, cholesterol content of liver and aortic wall in the high-fat fed rats. Under light microscope, there were lipid droplets and cholesterol crystal in liver of group high-fat. Compared with the group high-fat, the rats had a significant decrease of those measurements in serum or in tissue in the alfalfa and perilla group. Conclusions: The extract mixture of alfalfa and perilla could prevent the increase of serum TC, LDL-C, cholesterol content of liver and aortic wall in high-fat fed rats, and also prevent the fatty infiltration and cholesterol deposit of liver.

Vildagliptin is a potent and specific inhibitor of dipeptidyl peptidase 4,which has been implicated to enhance and prolong the physiological actions of incretion hormones including glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide.Vildagliptin is an orally administered drug and has been licensed for the treatment of type 2 diabetes mellitus.Vildagliptin monotherapy or in combination with other drugs can effectively lower glycosylated haemoglobin levels to a great extent.In addition,vildagliptin acts in a glucose-dependent manner,explaining its low risk of hypoglycemia.This drug has been proved well tolerated with few gastrointestinal side effects or oedema.Therefore vildagliptin is a promising new option for type 2 diabetic patients,and these patients would achieve better glycemic control and fewer complications in the long run.

Diabetes is a common disease,serverely harmful to the human's health and life quality.The pancreatic islets transplantation can correct the patient's hyperglycemia,stop or even reverse the progress of the complication and thus decrease the mortality of diabetic patients.It is the most safe and efficient therapy for diabetes.Since the Edmonton Protocol got success in pancreatic islet transplantation in 2000,it has been more and more interested because of its great clinical curative effect.Research strategy of islet transplantation is now focussed on increasing the acquired islets with normal viability,selecting the best transplantation pathway,and improving the immunosuppression protocol.The shortage of human pancreatic donor is an ever unsolved problem in clinical application.The potential resolutions may include acquisition from xenogenic-islets;islets originated from stem cells,and islets from the living-donor human pancreas.The islets transplantation will open a new application field for interventional radiology.(J Intervent Radiol,2006,15: 577-579)

Kidney damage caused by inappropriate use of some chinese herb drugs are quite common in our country. This review give a brief introduction of those reports concened, which include the most frequently used herb drugs of Aristolochia and their main components, the pharmacokinetic of Aristolochic acid, the different clinical manifestation of chinese herb nephropathy and the possible mechanism of the nephrotoxicity of Aristolochic acid.

To promote the development of key discipline construction in hospitals,we described the integration of refined management into the construction of key disciplines and different aspects including personnel training,featured specialty,research,and hardware were discussed.We concluded that refined management in essential to the development of hospital,and a mechanism needs to be established to ensure the long-term effect.

OBJECTIVE:To study the pharmaceutical human resources management and new management modes.METHO_DS:Survey and analysis were based on the relevent literature and combined with the actual situations of human resources man_agement of pharmaceutical enterprises in China.RESULTS & CONCLUSION:Only by raising the level of human resources management and practicing new management modes,will the pharmaceutical enterprises get sustained benefit of the company and society.

Objective: To study the stability of four kinds of cardiovascular ready-prepared Chinese medicine (Injections of Ciwujia, Shenmai, Dengzhanhuasu and Gegensu) in Betahistine Hydrochlorizel Sodium Chloride Injection. Methods: Four kinds of drugs were added into Betahistine Hydrochloride Sodium Chloride, respectively, and mixed, then observed for 6 hours at 23?C. Results: The appearance, pH value and concentration of four drugs above mentioned were stable in Betahistine Hydrochloride sodium chloride sodium chloride at room temperature (23?C) and in 6 hours. Conclusion: Injections of Ciwujia, Shenmai, Dengzhaihuasu and Gegensu are stable in Betahistine Hydrochlonile Sodium Chloride.

Objective To determine the incidence of long bone lesions and clinical characteristic in early newborn with asymptomatic congenital syphilis. Methods The syphilis antibody in 26 infants with asymptomatic congenital syphilis who were diagnosed and treated in our hospital from April 2001 to May 2004 were detected,and the clinical feature and X-ray features were analyzed.Results Twenty-six infants and their mothers all had the antibody positive of syphilis.Treponemal antibody titer were 4 times higher than their mothers in the infants blood serum.Their general conditions showed normal and had no symptoms when they were hospita-(lized).Then,there were 24 cases (92%) with positive physical signs and /or abnormal findings on the liver function tests and blood routine and long-bone radiographs.Long-bone radiographs were abnormal for approximately 38%(10 of 26)of asymptomatic newborns with congenital syphilis.Metaphysitis was shown and looked like sandwich biscuit in X-ray photograph.Conclusions Asymptomatic congenital syphilis has no symptoms in the early stage.Bone X-ray photograph should be included in the assessment of newborns with a positive serology.Further support is needed in the diagnosis and treatment of early newborns with asymptomatic congenital syphilis.
