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.

OBJECTIVETo observe treatment efficacy of acupuncture at different distal acupoints for acute lumbar sprain after massage.

METHODSOne hundred and fifty patients with acute lumbar sprain were randomly divided into a Yaotongdian (Extra) group, a Houxi (SI 3) group, a Weizhong (BL 40) group, a Chengshan (BL 57) group and a Shuigou (GV 26) group, total 5 groups, 30 cases in each one. After the same massage treatment and based on groups divided, different distal acupoints above-mentioned were selected to be acupunctured. Visual analogue scale (VAS) scores, lumbar activity and treatment efficacy of patients in 5 groups were evaluated.

RESULTSWith acupuncture at distal acupoints after massage,VAS scores of patients in 5 groups were decreased compared with those after massage treatment (all P<0.05); lumbar activity was all obviously improved (all P<0.01); and cured and markedly effective rates were all increased in comparison with those after massage (all P<0.01). But among 5 groups the differences of VAS scores, lumbar activity and cured and markedly effective rates were not statistically significant(all P>0.05).

CONCLUSIONBased on massage treatment, acupuncture at distal acupoints could further improve the treatment efficacy for acute lumbar sprain, but there is no obvious effective difference among every distal acupoint. As long as choosing acupoints with lower pain threshold and stimulating enough, good efficacy could be acquired for acute lumbar sprain.

Lipocalin-2 is an adipocytokine secreted mainly by adipose tissue. Increasing lines of evidence suggest that lipocalin-2 is an inflammatory factor associated with insulin resistence, obesity and its complications. The precise mechanism of the development of obesity-related disorders induced by lipocalin-2 is not very clear, however, it may be a useful target in drug therapy for obesity-related metabolic and cardiovascular diseases.

Through the network medical teaching and guidance system,the live video of clinical medicine activity can be multicast by MPEG2 code and MPEG4 code simultaneously on the LAN or WAN.It may meet the request of different network bandwidth,realize the bidirectional audio or video frequency at the same time,and satisfy the clinical teaching or guidance need.The client port can be deployed in the random terminal on LAN or WAN,while the user with the authorization can see the high clear surgery image in real time at any place,make communication through the bidirectional audio and video system,and even remotely control the camera's lens angle and focus for perfect video effect.

Objective:To study the bidimensional model of self-esteem and the relationship between self-esteem and self-consistency and congruency.Method:591 college students completed Rosenberg Self-Esteem Scale and Self-Consistency and Congruency Scale. Amos4.0 was applied to analysis the unidimensional model and the bidimensional model of self-esteem, regression between self-esteem and self-consistency and congruency were then analyzed.Results:The bidimesional model of self-esteem fit the data better (?2=126.52,df=34, ?2/df=3.72, CFI=1.00, TLI=0.99, RMSEA=0.07), and dissociation effect between self-consistency and congruency and positive dimension and negative dimension were found.Conclusion:The study tends to support the hypothesis of the bidimensional model of self-esteem.

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.
