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.

ObjectiveTo observe the effect of intrathecal injection with Rocephin on intracranial infection after traumatic brain injury.Methods12 patients with intracranial infection after traumatic brain injury were treated with Rocephin, including Rocephin 2.0g vein injection twice a day and 0.1 g intrathecaluse once a day. The germiculture and drug sensitivity test were made before the treatment and antibiotic was selected.ResultsThere were 6 cases recovered, 2 cases improved markedly, 1 case improved and 3 cases unchanged. The efficient rate was 66.7%. The examination of cerebrospinal fluid showed that the levels of leucocyte and protein decreased, the glucose and chloride increased and encephalic pressure declined. 12 bacteria were verified in 12 cases and 8 bacteria were eliminated after treatment. The bacterium cleared rate was 66.7%. There were no side effects correlatives with Rocephin.ConclusionVein and intrathecal injection with Rocephin is effective on intracranial infection after traumatic brain injury.

ABRO1 (Abraxas Brother 1), known also as KIAA0157 or FAM175B, is an important component of BRISC deubiquitinating enzyme ( DUB) complex which specifically shears K-63 linked polyubiquitin chains .This article reviews the research progress in ABRO 1 in terms of its structural characteristics , BRISC complex composition , the regulation of DUB activity and interferon response , oxidative stress response and anti-myocardial ischemia and provides new ideas on fur-ther study of the physiological function of ABRO 1 and its association with immune and cardiovascular diseases .

Objective To observe the effect of acupuncture on patients with vertebral-artery-type cervical spondylosis by means of transcranial Doppler sonography ~TCD) and brainstem auditory evoked potentials ~BAEP), and to explore the mechanism of acupuncture in treatment of cervical spondylosis by means of blood velocity and neuroelectrophysiology measurements. Methods Forty patients with vertebral-artery-type cervical spondylosis were divided into acupuncture treatment group ~20 cases) and routine treatment group ~20 cases). The TCD and BAEP were examined before the rehabilitation treatment and 2 week later. Comparing with the control group, the effect of acupuncture on the blood velocity and cerebral electrophysiology was analyzed. Results ~1)The total efficiency rates in the two treatment groups were 90% and 85%, respectively. The clinical heal rate was 45% in acupuncture group and 35% in routine group. There was no statistic difference with regard to the therapeutic effect and the length of treatment between the two groups. ~2)The blood velocity of vertebrobasilar artery ~VBA) in the patient group was decreased. The abnormal rate of TCD was 77.5% ~31/40 cases), characterized with the decrease of VBA. The abnormal rate of BAEP was 75% ~30/40 cases), characterized with brainstem abnormality type. ~3)The blood velocity in both groups was increased after treatment. Compared with the routine therapy group, the velocity of blood flow in vertebral artery in acupuncture treatment group was increased markedly ~P

[Objective]To Study the sensitive sequence of MR for all stages of articular cartilage erosion and to evaluate the effect of MR on the correct diagnosis in the early stage of articular cartilage.[Method]One human fresh amputated knee joint and 4 normal pig knee joints were used to study and select the best sequence by T2WI,PDWI,GE,STIR,3D FS-FSPGR sequences and 6 pig oatcoarthritis(OA)model knee joints were studied by the selected best sequence,MRI was compared with correspont histological evidence to evaluate the effect of MR on the correct diagnosis of OA cartilage.[Result]The best results of tissue resolution and diagnosis rate were seen in 3D FS-FSPGR of all five sequences respectively 67.9% and 93.7%,of proteogly(PG)and collagen fiber(CF)mainly distributed in the deep cantilage.Dyeing of PG in diffent cantilage erosion was decreased while CF increasing.[Conclusion]3D FS-FSPGR is a favorable scan sequence to examine the OA changes of articular cartilage.MRI could show the pathological changes including early stage and have good veracity to the early pathological changes of OA cartilage.
