Objective To achieve systemic and efficient management of the hospital variety of medical equipment,simplify the day -to -day inspection of work. Methods The software part's development used Delphi7.0 and SQL Sever 2000 separately as the onstage development kit and the backstage database; the hardware part,Anti-metal Mifare1 card as the RFID tag,MSR-100 and HDT-3000 as reader were used. Results Test to the system indicates that in the 0～40 mm scope,both of the readers can accurately read and write the tag which adheres to the metal surface,and almost without direction limit. Conclusion Compared with ordinary data bank administration software,this system not only has the basic function such as data's increase,deletion,revision,preservation,backup and restore and so on,but also realizes information exchange between the electronic tag and the database through the serial port and the corresponding submodule; The handle-reader's application especially makes the complicated daily inspection easy and readily achievable,which improves maintenance efficiency,meets the needs of efficient dynamic medical equipment management.

Objective To discuss the accuracy of 3DSS three-dimensional scanning system, which was used to reconstruct the 3D digital model of unilateral orbital defect patients. Methods By using 3DSS spectrometer on the case of patients with unilateral orbital defect, the related scan dates of facial structure were collected, and the reconstructed digital models were processed wax pattern by SLS prototyping machine. Results The digital solid model of three-dimensional reconstruction was smooth and complete, and border over the natural. The designed resin prosthesis can be inosculated with the orbital defect tightly and symmetrically. Conclusion To adopt the system can be successfully completed unilateral orbital defect restoration design and production, and ultimately satisfied the clinical requirement of prosthesis production.

Objective To investigate the risk for recurrent thyroid carcinoma.Methods Clinical data of 56 cases of recurrent thyroid carcinoma were retrospectively analyzed and summarized possible causes of relapse.Results Student's test revealed that age,initial operative approach,pathological types,postoperative medication and radionuclide therapy were associated with recurrence (P ＜ 0.05),but gender was not associated with recurrence (P =0.240),and resection of single gland was associated with recurrence (P =0.006),but resection of both gland was not so (P =0.153).Multivariate analysis indicated that initial operative approach was the dependent factors for recurrence(P ＜ 0.05).Conclusion Some patients that prone to recurrence should be strengthened regular follow-up.Standard treatment should be used for The recurrences diagnosed.

Objective To study the imaging manifestations of parietal coronary artery and the diagnostic value with 64-slice spiral CT.Methods 1000 patients with clinically suspected coronary heart disease underwent 64-slice spiral CT scan,the images were dealed with curved planar reconstruction and analysed at workstation.Results Parietal coronary arteriae were found in 380 patients,among them,314 cases were at the LAD,32 cases were at the CX,13 cases were at the RCA and multiple arteriae involved in 21cases.Conclusion 64-slice spiral CT coronary angiography is an effective methed in diagnosis of parietal coronary artery.

Papillary thyroid microcarcinoma (PTMC) is a subtype of papillary thyroid cancer,and there are many debates about its treatments,including extent of thyroidectomy,necessity of prophylactic central-neck nodal dissection,risk-benefit ratio of thyroid-stimulating hormone suppression and indications of observation therapy,et al.The epidemiology and treatment programs of thyroid PTMC were reviewed in this article.

Objective To investigate the role of sLOX?1 and leptin in metabolic syndrome ,glucose and lipid metabolism. Methods 58 patients with metabolic syndrome were included in the study ,with other 35 normal controls as control group. Fasting venous blood samples were collected. ELISA method was used to detect serum sLOX?1 and leptin levels. The related biochemical indicators were tested. Results The sLOX?1 and leptin levels in the metabolic syndrome group were significantly higher than those in the control group(P < 0.01). The levels of sLOX?1 and leptin were further compared between different genders. The differences were not statistically significant (P > 0.05). sLOX?1 and leptin levels were positively correlated. They were positively correlated with WAIST,TG,SBP,DBP,and negatively correlated with HDL?C. Leptin and age,FPG also had positive correlation,but sLOX?1 was not correlated with age and FPG. Conclusion sLOX?1 may be able to predict endothelial damage in patients with metabolic syndrome in an early stage. Combined with leptin ,the endothelial dysfunction could be reflected more accurately. They may be the important factors for early diagnosis and risk assessment of metabolic syndrome.

0.05).There was a positive corrlation on CD40~+ and CD40L~+ in chronic B hepatitis patients.There was a positive corrlation on CD8~+/CD28~+ and CD40~+、CD40L~+ in chronic B hepatitis patients.There were no remarkable corrlation on CD8~+/CD28~- and CD40~+、CD40L~+ in chronic B hepatitis patients.Conclusion:The costimulation molecules CD40~+、CD40L~+ and CD8~+/CD28~+ are lower,while CD8~+/CD28~- are higher in chronic B hepatitis patients than in the health.To test the expression of CD40~+、CD40L~+ and CD8~+/CD28~+ on peripheral blood of the chronic B hepatitis could help to evaluate patients's celluar immunity and guide clinical treatment.

Aim To investigate HPA axis change relation with glucose and lipid metabolism.Methods Wistar rats were injected intraperitoneally with STZ (30 mg·kg~(-1)) after fed with high lipid food for two months, then rats with blood glucose of over 15 mmol·L~(-1) were used in the experiment. Animals were divided into four groups: normal group, diabetic model group, treatment group (ROS 200 mg·kg~(-1) ·d~(-1) ig), and metformin group (200 mg·kg~(-1)·d~(-1) ig).Rats were decapitated after they had been administered ig for four weeks and were 24 hour urine collected.Plasma CRH, ACTH, corticosterone, hypothalamic CRH, ACTH of pituitary gland, 24 hour urinary corticosterone and plasma insulin were determined by ELISA and radio immunity kit respectively.Results In diabetic rat model induced by high lipid food and STZ, plasma and urinary glucose level and plasma TC, TG levels were increased, plasma HDL-C and hepatic glycogen content were reduced, which was synchronized with changes of higher pituitary ACTH, plasma and total 24 hour urine corticosterone excretion.Conclusion The disorder of glucose and lipid metabolism of model induced by high lipid food and low dose STZ may be linked to the change of HPA axis.The improvement of ROS on glucose and lipid metabolism in diabetic rats may be linked to the decrease of HPA axis activity.

Objective To improve the informatization of field clinic for quicker and more effective cure of the wounded and the sick.Methods Making the use of the experiences from many years' application of No.1 Military Medical Project,the digital field clinic was set up based on HIS under the circumstances of wireless network.Results The digital field clinic provided convenience for doctors and nurses,optimized the curing procedure,standardized the material management,improved the curing efficiency,and enlarged the curing scope.Conclusion The digital field clinic facilitates the data transmission of medical nursing and assistant diagnosing photos.During the implementing process,the digital field clinic also provides new ways and ideas for the informatization of medical support of other types.

OBJECTIVE To investigate and analyze hand carrier state of medical staff in Tianjin and the antibiotic resistance of the pathogens.METHODS Bacteria or pathogens were isolated from the samples using a sterilized cotton swab on the whole hand before hand washing or hand disinfection,and drug sensitivity test was performed.RESULTS In 16.72% of all samples(50/299),there were 64 kinds of bacteria or pathogens isolated.A.baumannii,Staphylococcus aureus and A.lwoffii were the most common bacteria,40.6% resistant to more then 3 kinds of drugs.Four Meticillin-resistant S.aureus(MRSA) strains were detected out.CONCLUSIONS The high rate of hand carrying bacteria and resistance in Tianjin should pay attention to.
