Objective To observe effect of large blood vessel hypoxia on the Wister rat′s NO activity. Methods Thoracic aorta rings model with full endothelium and removed endothelium of Wistar rat were prepared , hypoxia stimulated aorta rings and noted changes of constriction extent. Results Endothelium full , removed endothelium aorta rings by hypoxia contract extent difference was 598?42mg and 208?38mg, both had significance discrepancy (P0.05), and NTG made blood vessel contract to reduce range, reach 57.21% (P

Objective To study the technique and clincal value of biopsy during percutaneous vertebroplasty for the diagnosis of spine lesions.Methods From January 2003 to November 2005,94 patients that had been diagnosed with spinal tumors were admitted to our hospital.In these cases,totally 120 vertebrae were involved,including 3 cervical vertebrae,41 thoracic pieces,72 lumbar segments,and 4 vertebrae.Among the vertebrae,lyric lesions were found in 91,blastic in 9,and mixed in 20.Before operation,primary lesion of the spinal metastatic tumor had been confirmed in 76 patients (87 vertebrae).All the cases received percutaneous vertebroplasty,and biopsy was perfromed during the surgery.The positive rate of the pathological diagnosis was then analyzed.Results The percutaneous vertebroplasty and biopsy were completed in all the cases with a success rate of 100%.Of the 120 vertebrae,the primary diagnosis was confirmed in 114 (positive rate 95.0%),and the positive rate for metastasis cases were 93.1% (81/87).No injuries to the nerve and vessels were found in this series,no patient developeed hematoma or infection after the operation.A mean of 36.4-month follow-up was achieved in 80 patients (range,4 to 68 months),during this period,no tumor cells spreaded along needle tract or implanted into the skin.Conclusions Biopsy during percutaneous vertebroplasty can not only shorten treatment time and save medical cost,but also increase the safty of the surgical treatment as well as the aecruracy of pathological exmaination.

Objective To determinate Berberine chloride in compound Wuzhigan capsules and develop a steady and reliable method for the quality control of the capsules.Methods A HPLC method was adopted.The column was Diamonsil C18 (250 mm?4.6 mm,5 ?m) with the column temperature of 30 ℃,the mobile phase was acetonitrile-0.033 mol/L potassium dihydrogen phosphate (30∶70) with the flow rate of 1.0 mL/min,and the detection wavelength was at 347 nm.Results Berberine chloride has a linearity in the range of 2.52~12.6 ?g/mL,and the average content in the capsules was 1.686 mg/capsules.Conclusion This method is sample,accurate,and can be used for the quality control of compound Wuzhigan capsules.
4.Application progresses of optical molecular imaging techniques in cancer
Chinese Journal of Medical Imaging Technology 2017;33(9):1417-1420
The molecular imaging technology is a kind of imaging technology which displays the microstructure of tissue,cell and sub cellular level in vivo.It has the characteristics of real time,noninvasive,accurate and sensitive,and can be used for early screening and diagnosis of tumor at the cellular and molecular level.Following the development of bioluminescence and fluorescence imaging,optical molecular imaging technology is making rapidly progression.The application of optical molecular imaging technology in cancer was reviewed in the paper.

Objective To evaluate the value of spiral CT in analyzing correlation of growth pattern with pathology and prognosis in gastric stromal tumor(GST).Methods CT findings and pathological data including immunohistochemical staining sections of 43 patients with GST were reviewed and all patients were followed.The correlation between growth pattern,pathology and prognosis was studied.Results Of the 43 GST,there were benign in 9 and malignant in 34.the benign or malignant GST closely correlated with the growth pattern.Of the 17 intra-and extra-luminal growth patients,16 cases were malignant and 5 cases recurred in 3 years.Conclusion The GSTs that appear intra-and extra-luminal gowth hint the poor prognosis.

Objective To evaluate the effect of behavioral intervention on changing knowledge, attitude and practice (KAP) about AIDS among the migrant workers in railway construction sites. Methods Health education and behavioral intervention on AIDS were carried out among the migrant workers for 4 to 5 months, who were clusteredly sampled from two railway construction sites, in the forms of mini-media, peer education and so on. Questionnaire survey was conducted among them before and after the intervention. Results The results showed that the knowledge awareness of the migrant workers on the transmission routes, preventions of AIDS and self-protection consciousness increased significantly by comparing the indexes of 943 pre-intervention with those of 671 post-intervention workers. After intervention procedures, the rate of those workers who would adopt negative attitudes towards the HIV infected persons because of fear and discrimination was decreased from 9.8% and 10.5% to 6.3% and 3.5% (both P

Objective To investigate the specific application of ergonomics for design of operation field in sanitary train. Methods The use of ergonomics theory, the layout of operation field, personnel operating capacity, environmental comfort and operation security were analyzed, surveyed and discussed. Results The principles and guidelines for design of opera- tion field in sanitary train were proposed in order to make full development the efficiency of "operator-equipment-environ- ment" mode. Conclusion The application of ergonomics for design of operation field in sanitary train can be improved the rationality of the layout of field of operation, environmental comfort and work efficiency.

The rapid deployment flow for medical support unit of health-care train is discussed in the aspect of personnel spot-training with carriage. A handbook is compiled for loading and unloading health-care train's equipment. A series of methods and processes are put forward based on the principle of " fixed type of equipment, fixed person for loading or unloading, fixed position, fixed operation steps", which provides a possibility for rapid deployment flow at medical support unit.
