The rapid development of modern science and technology pushes mdeical progress.Med- ical engineering makes its first appearance with the development of medicine.It certainly exercises a pos- itive effect on the quality of medical treatment,nursing service and medical research.The development of science and technology calls for strengthening the construction of medical engineering which is to play the role of obtaining informatioon on medical instruments and equipmient,working out purchase plans, taking charge of installations,checking contracted purchases of goods and services before acceptance, making records,starting a good job of quantified administration,and technically guiding the operation of equipment.Both the society and the unit concerned may be highly benefited through tightening the con- trol of equipment purchase,cost recovery and depreciation.

Objective To evaluate the value of CT and ultrasonography in the diagnosis of originative malignant tumors of the female internal genitals.Methods 147 cases of originative malignant tumors comfirmed pathology in the female internal genitals were restropectively analyzed.Among them,73 cases were examined by CT.The CT findings were analyzed and compared with ultrasonography.Results Ultrasonography was proved to be slightly superior in the rate of definite diagnosis and also the cost was lower than CT.Conclusion The authors recommend that ultrasonography examination may be used as screening method for the orignative malignant tumors of the female internal genitals,and CT may be used as a important complementary method.

Objective:To investigate the super selective transhepatic arterial embolization (TAE) for effects of cyst volume and liver function in patients with symptomatic polycystic liver disease (PLD), and provide a reliable basis for clinical diagnosis and treatment. Methods: 14 cases of symptomatic patients with PLD were selected from October 2014 to October 2015 in our hospital using super selective hepatic arterial embolization. The upper abdomen was performed CT scan one year after surgery, and the volume of patients with liver cyst was tested. We observed the changes of total volume of liver before TAE and postoperative kidney function, adverse reactions, and the improvements after four months’ follow-up.Results: The angiography for the 14 patients showed liver volume increased in different degrees. It also showed that blood supply was mainly hepatic artery wall branch. There were different sizes of liver round unstained area. There was consistent between CT examination and unstained area in polycystic liver swollen area. The difference of the total volume of the liver cyst was statistically significant in 14 cases of the patients with PLD before TAE treatment and after 12 months’ treatment (t=2.8627,P<0.05). 14 cases of the patients with PLD after TAE before treatment and after 1 week’s laboratory tests, the difference was not statistically significant among AST, ALT, ALB and TBIL (t=0.0441,t=0.3316,t=0.0722,t=1.9855;P>0.05). Compared with the preoperative, there was little effect on liver function by TAE. After 3 to 12 months, symptoms gradually improved and physical rating increased. The improvement rate was 100% after 12 months and the physical score was from 90 to 100 points. The embolism syndrome in 14 cases of patients gradually disappeared after 1 to 5 days, and five days later the symptoms disappeared. Conclusions: There is a significant effect for symptomatic polycystic liver patients with TAE. It can improve efficacy and reduce patient suffering with a low recurrence rate. It is worthy of clinical application.
