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.

AIM: To compare the therapeutic effects, adverse reactions and the costs between recombinant human growth hormone(rhGH) and human serum albumin(HSA) in treatment of liver cirrhosis patients with hypoproteinemia METHODS: Using pharmacoeconomic cost-effectiveness analysis , rhGH was compared with HSA in treatment of 66 liver cirrhosis patients with hypoproteinemia(divided into two groups). RESULTS:After 4 weeks treatment, the effective rates of rhGH and HSA we- re 69.70% and 84.85%, the cost-effectiveness ratios were 27.36, 38.89, respectively. After 8 weeks treatment, the effective rates of rhGH and HSA were 78.79% and 54. 57% ,the cost-effectiveness ratios were 2420, 60.47, respectively. CONCLUSI- ON: rhGH can effectively treat liver cirrhosis with hypoproteinemia and can obviously increase serum albumin level. From a Long-term point of view, its cost effectiveness ratio is superior to that of HSA.

Objective To study the effect of Tongfu Qingxia Decoction on the barrier function and inflammatory reaction regulation of intestinal mucosa in acute pancreatitis patients.Methods Patients selected were randomly divided into two groups.Routine treatment was conducted in control group,while Tongfu Qingxia Decoction was added in treatment group.Plasmic endotoxin,tumor necrosis factor-?(TNF-?)and interleukin-6(IL-6)were observed before and after treatment.Results After treatment,plasmic endotoxin,TNF-? and IL-6 decreased and interleukin-2 increased significantly in both groups(P

Type 2 diabetes mellitus(T2DM)is a complicated endocrine disease caused by both genetic and environmental factors,many of which are unknown as far as for the pathogenesis of T2DM is concerned. In recent years,diabetes researchers have paid more attention to the intestinal microbiota. The discovery,verification and molecular mechanism of the intestinal microbiota related to T2DM are the focus of this article. The role of intestinal microecology in the development of T2DM is also reviewed,involving diet,chronic inflammation,short chain fatty acids,bile acids,the intestinal microbiota and circadian rhythm,and microRNA.

Objective To explore the efficacy and safety of plastic titanic plates internal fixation in the treatment of intra-articular calcaneus fracture.Methods 42 patients with intra-articular calcaneus fracture were selected and taken lateral calcaneal improvement “L” shaped incision for the correction of calcaneal shortening and valgus deformity.Skidmore needle went through collapse of the articular surface below from calcaneal fractures after block nodules along with bone shaft,and restored Bohler angle,Gissane angle and bone length,height,and the lateral fracture piece was reset.The fixation was taken by plastic reconstruction titanic plates,and the fracture was inspected by Xray.Results In 42 patients,the fracture healing time was (11.4 ± 0.6) weeks.The fracture position was good on the line,and the articular surface of calcaneus and talus was smooth,and the Bohler angle,Gissane angle of calcaneus were returned to normal.The excellent rate was 90.5％ by Maryland score.No surgical causes of broken plate and screw breakage were found.Conclusion Internal fixation with open reduction and plastic titanic plates internal fixation for the treatment of intra-articular calcaneal fractures has a significant effect and safety,which is worthy of promotion.

Health care policy should follow principles of total efficiency, no-harm, fairness and justice as ethi-cal standards for public policy. Diagnosis Related Groups( DRGs) as a sign of new health care reform ( NHCR) is implemented as a pilot program across the country, with the obvious function of suppressing excessive growth in medi-cal costs and over-treatment. From the dimension of ethical values, the DRGs has avoided unethical individuals, fol-lowed the principle of total efficiency and achieved the equalization of social security. However it has also increased ethical risks and been adverse to the development of medical research. To realize the reasonable development of DRGS, the construction of DRGs must be improved, and security policies must be reasonable and feasible; orderly measures must be established to ensure promotion and implementation;the government’s financial investment must be increased to protect the social welfare of public hospitals;a sound communication mechanism must be implemented, and interaction between medical institutions and insurance institutions must be strengthened.

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.
