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.

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.

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.

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)

Objective To investigate the compassion fatigue and stress status and the relationship between them of nurses working in secondary hospitals of integrated areas of urban and rural places, and explore the social factors that influence the compassion fatigue and stress status. Methods 378 nurses from secondary hospitals in urban-rural integrated area were selected as samples in Nanjing. Paramedic′s Compassion Fatigue Scale and Chinese Nurse Stressor Questionnaire were adopted to develop the survey. Results The nurse compassion fatigue score was (15.9 ± 1.83) points; Stress status score was (86.18 ± 19.96) points. Urban-rural fringe secondary hospital nurse compassion fatigue status was positively associated with the pressure (r=0.218, P<0.01), and loss of enthusiasm, nervousness, loss of ability to doubt, and morale were on the medical staff work pressure had significant influence (P<0.05). Conclusions The nurse compassion fatigue and stress level were in the medium level; Nursing managers should pay more attention to the psychological health level of the nurses, increase nurses' enthusiasm, alleviate the occupational stress of nurses caused by compassion fatigue.

Objective To investigate clinical therapeutic effect of valsartan/amlodipine compound preparation on patients with hypertension. Methods From Juue 2011 to June 2013, a total of 110 columns with hypertension as the research object, according to randomly divided into two groups.Valsartan/amlodipine compound preparation(group A) and amlodipine combined with metoprolol group(group B), continuous administration for 24 weeks, patients symptoms, former state, improve heart function and blood clots compared curative effect were monitored.Results After 24 weeks of treatment with valsartan/amlodipine compound preparation group, compared with group B, SBP and DBP were decreased significantly, the TC, TG and Glu content were also decreased significantly, clinical symptoms improved ratio was 90.91%(P<0.05).Cardiac function improvement recovery was 89.09%(P<0.05).D-Dimer level was decreased significantly(P<0.05), the former state blood clots were effectively prevented.Conclusion The high blood pressure in treatment with valsartan/amlodipine compound preparation has more therapy advantages in clinical treatment .
