1.Treatment of neuroblastoma
International Journal of Pediatrics 2014;41(6):621-624
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.
2.The effects of the extract mixture of alfalfa and perilla on lowering serum lipid, protecting liver and aortic wall in rats
Parenteral & Enteral Nutrition 1997;0(04):-
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.
3.A SEM STUDY OF STRUCTURE IN THE RABBIT COCHLEAE
Acta Anatomica Sinica 1955;0(03):-
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.

6.Intraductal Papillomas of the Breast:the Potential Cause of Misdiagnosis of Shear Wave Elastography in Diagnosis of Benign and Malignant Breast Lesions
Chinese Journal of Medical Imaging 2015;(12):896-899,904
PurposeTo evaluate the shear wave elastography in diagnosis of intraductal papillomas, benign or malignant breast lesions.Materials and Methods From December 2013 to December 2014, 145 female patients with 155 lesions who underwent ultrasonography and shear wave elastography in general hospital of PLA were retrospectively studied. All the lesions were confirmed by pathology via surgery or biopsy. The performance of the maximum elasticity, the mean elasticity, the minimum elasticity values and the elasticity ratio in diagnosis of benign and malignant tumors were analyzed. The portion of intraductal papillomas in misdiagnosed cases was calculated. The elasticity values of intraductal papillomas were compared with those of other breast benign and malignant lesions.ResultsAmong 155 lesions, pathology confirmed intraductal papillomas in 20 lesions, fibroadenosis in 23 lesions, fibroadenoma in 23 lesions, inflammation in 9 lesions, adenosis with fibroadenoma in 17 lesions, and breast cancer in 63 lesions. The maximum, mean, minimum elasticity values and the elasticity ratio of intraductal papillomas were (84.39±74.08) kPa, (51.33±46.36) kPa, (26.55±24.98) kPa and 2.80±2.18, respectively. The elasticity values of intraductal papillomas were between those of breast cancer and other benign lesions, and there were no statistically significant (P=0.003).ConclusionThe elasticity values of intraductal papillomas were between those of breast cancer and other benign lesions, which may be a potential reason to cause misdiagnosis using shear wave elastography to differentiate breast benign and malignant diseases.

10.Surgical strategy for synchronous colorectal liver metastases
Chinese Journal of Digestive Surgery 2009;8(5):327-330
Synchronous colorectal liver metastases occurs in 15%-25% of patients with newly diagnosed colorectal cancer. Hepatic resoction has been accepted as the only option that offers long-term survival for patients with liver metastases. However, the optimal timing and sequence of resection for synchronous colorectal liver metastases still remain controversial. Also, the use of neoadjuvant chemotherapy which should be initiated in patients with resectable synchronous liver metastases is not consistent. In order to use evidence-based medicine to clarify indications for one-stage hepatic resection of liver metastases, a multi-center clinical trial was pedormed to normalize the surgical strategy of synchronous liver metastases. In summary, in selected patients, one-stage approach is comparable to the two-stage procedure in mortality and morbidity rates and longterm survival. One-stage procedure should be performed according to the site of primary tumor, age, the volume of residual healthy liver. Preoperative chemotherapy is effective in downstaging the tumor and reducing the resected liver volume, but it also brings damage to the liver and has adverse effect on onestage hepatic resection.
