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.

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.

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.

Gastric cancer is one of the most common malignancies in China. Currently, surgical resection, chemotherapy and radiotherapy are still the main therapeutic methods.The postoperative 5-year survival of patients with gastric cancer is lower than 60%. As a means of adjuvant therapy, immunotherapy has the potential to improve the survival of patients with gastric cancer, because its therapeutic targeting and toxicity profile does not overlap with those of conventional therapies. The effector cells of the immune system (T, B and NK cells), when activated, are able to lyse and destroy tumor cells through specific recognition of tumor-associated antigens. However, most immunotherapy research in gastric cancer is still limited to the preclinical stage due to the weakness of its antigenicity. With the development of tumor immunobiology and genetic engineering, immunotherapy has become the focus of research for the treatment of gastric cancer.

OBJECTIVE One of the objective of the study was to analyze the reliability and validity of the Chinese version of Glasgow children's benefit inventory (GCBI). The other was to explore whether the Chinese version of GCBI could be used as a appropriate evaluation method on children's quality of life (QOL) after tonsillectomy and adenoidectomy (T&A). METHODS Firstly, seventy-three eligible children and their proxies were interviewed with this survey scale, the survey scale was assessed by split-half reliability, internal consistency, content validity and construct validity. Second, the Chinese version of GCBI used to evaluate the changes of these 73 children's QOL at 12 to 18 months after operation. RESULTS First, the reliability coefficient and the construct validity of the Chinese version of GCBI was satisfactory. Second, almost all children's QOL changed better after operation, it improved the most in physical aspects. CONCLUSION The Chinese version of GCBI had good reliability and validity, and is suitable for assessing QOL of children after T&A. It can help clinician evaluate therapeutic effect in pediatric otolaryngology.

Objective To observe the effect of acupuncture plus electromyographic biofeedback therapy (EMGBFT) on the nerve function, activities of daily life (ADL), biochemical indexes, and lower-limb function in cerebral stroke patients. Method Totally 102 cerebral stroke patients in recovery stage were recruited and allocated to an observation group and a control group by using the random number table, 51 cases in each group. The two groups were both given conventional treatment, based on which, the control group was given EMGBFT, while the observation group was given acupuncture plus EMGBFT. The treatment duration was 8 weeks in both groups. The changes of National Institute of Health Stroke Scale (NIHSS), ADL, endothelin 1 (ET-1), calcitonin gene-related peptide (CGRP), and Fugl-Meyer Assessment (FMA) of the lower-limb motor function were compared. Result The NIHSS scores dropped and ADL scores increased significantly in the two groups after the intervention (P<0.05);after the intervention, the NIHSS score of the observation group was lower than that of the control group and the ADL score was higher than that of the control group (P<0.05);in the observation group, the plasma ET-1 level decreased significantly and CGRP level increased significantly after the intervention (P<0.05);after the treatment, the plasma ET-1 level in the observation group was lower than that in the control group and the CGRP level was higher than that in the control group (P<0.05);the FMA scores increased markedly in both groups after the intervention (P<0.05);the FMA score of the observation group was higher than that of the control group after the treatment (P<0.05). Conclusion Acupuncture plus EMGBFT can significantly improve the nerve function and ADL, promote the recovery of lower-limb function, down-regulate the ET-1 level, and up-regulate the CGRP level in cerebral stroke patients.

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.

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)
