Objective To investigate MSCT findings of cystic masses of the neck.Methods The clinical and CT imaging data of 36 cases with cystic neck lesions including 1ymphsdenopathy 9 cases,abscesses 3 cases,salivary lesions 2 cases,thyroid lesions 2 cases,thyroglossal duet cysts 9 cases,branchial cleft cysts 5 cases,cystic hygromas 3 cases,deimoidcyst 1 case laryngeal mucocele 1 case and nerve sheath tumors 1 case comfired by operation-pathology were analyzed.Results The cystic features of lesions could be showed on contrast-enhaced CT,cystic alteration in lymphadenopathy were due to necrosis and presented as the cystic wall enhanced and thickened salivary cystic lesions were variable congenital cystic masses usually appeared as a smooth,well-circum scribed mass,the cystis wall Was thin and nonenhanced unless inflammation was present and most of them localized at the specific anatommic compartments thyroglossal duct cysts were mainly in the anterior midline portion of the neck at the level of the hyoid bone.Second branchial cleft was commonly in the posteriormargin of the subm and ibular gland and lateral to the carotid space.Dermoid cyst presented in the floor of the mouth.Conclusion CT can provide essential infonnatiom in evaluating the nature and location of the cystic mass of neck.which is of significance for diagnosis and preoperative planning.

Objective To investigate the clinical distribution and drug resistance of stenotrophomonas maltophilia and to provide reference for the clinical application of drugs and to control the nosocomial infection. Methods MicroScan autoSCAN4 and Kirby -Bauer (K -B)method were used to assess the bacteria and test the drug sensitivity.The data were analyzed with software WHONET5.6.Results The isolation rate was the highest in respiratory specimens.There was a highest isolation rate of 90.2%.Drug sensitive test showed that stenotrophomonas maltophilia was most sensitive to minocyline,and the resistance rate was 3.6%.The resistance rates of trimethoprim -sulfamethoxazole,levofloxacin and cefoperazone -sulbactam were12.2%,13.4% and 26.8%.Conclusion Drug resistance monitoring of stenotrophomonas maltophilia should be enhanced.Treatment based on drug susceptibility test should be adapted as soon as possible.

Objective To clone human neural RNA binding protein HuC cDNA,express and purify the recombinant human HuC(Hu antigen C)protein in E.coli.Method Human HuC cDNA was cloned by RT-PCR.HuC cDNA was inserted into the prokaryotic expression vector pGEX-4T-3.The recombinant protein HuC was expressed in E.coli BL-21,and purified by the GST Sepharose 4B affinity column.Results The(62 ku) recombinant GST-HuC fusion protein was obtained.Conclusion The recombinant human HuC protein was successfully prokaryotic expressed and purified.

Objective To investigate the value of high sensitive cardiac troponin T(hs-cTnT),human heart fatty acid binding protein(H-FABP),B-type natriuretic peptide(BNP),ischemia modified albumin(IMA) and creatine kinase(CK-MB) in the diagnosis of myocardial injury in preeclampsia.Methods A total of 50 women of normal pregnancy in preganancy group,and 50 healthy women without pregnacy were collected in control group,167 women in preeclampsia group (42 cases with myocardial injury,125 cases without myocardial injury).The serum IMA were detected by albumin cobalt binding test,H-FABP were detected by ELISA,hs-cTnT and BNP were detected by microparticle chemiluminescence immunoassay and CK-MB were detected by immuno-suppression.Results Five cardiac markers levels in myocardial injury group of preeclampsia group were significantly higher than those in healthy control group and normal pregnancy women and non myocardial injury group[(t=8.521,7.489,7.256;7.561,6.897,6.235;12.314,9.236,10.251;13.657,11.023,12.031;11.301,10.364,15.567),(P=0.008,0.030,0.035;0.027,0.031,0.033;0.002,0.005,0.003;0.002,0.004,0.003;0.003,0.004,0.001)].There was no significant difference in hs-cTnT among control group and normal pregnancy women and non myocardial injury group[(t=1.678,1.401;1.887,1.784),(P=0.339,0.401;0.289,0.398)].IMA、H-FABP、CK-MB and BNP in normal pregnancy women and non myocardial injury group were higher than in control group [(t=4.784,4.021;3.894,3.784;5.801,5.215),(P=0.024,0.032;0.037,0.041;0.021,0.029)].There was no significant difference in IMA,H-FABP,CK-MB and BNP between normal pregnancy women and non myocardial injury group [(t=1.325,1.257,1.241);(P=0.451,0.329,0.378)].The sensitivity of combined detection of five cardiac markers in preeclampsia myocardial injury was significantly higher than that in single marker(χ2=3.021,3.561,4.215,4.496,5.249;P=0.027,0.024,0.019,0.015,0.009).Conclusion When myocardial damage in pregnant women was determined by cardiac markers,pregnancy should be taken into account as a special physiological cycle.The combined detection of five cardiac markers is conducive to early diagnosis of ischemic myocardial injury in preeclampsia.

Objective:To discuss the application of lean management of medical consumables in stomatological hospital and evaluate the operation effect.Methods: Based on the lean management of medical consumables of School of Stomatology, China Medical University, the medical consumables are composed of high valuable and common consumables. Traceable and sub-base management are carried out for all the medical consumables.Results: Lean management runs well and improves the scientificity and precision of hospital management.Conclusion: The operation costs are reduced and management benefit is increased.

Though the development of non-surgical treatments has improved the local and systemic control of breast cancer, surgery still plays an important role. For early breast cancer, breast-conserving surgery (via periareolar incision and/or axillary incision for some suitable cases), skin-sparing mastectomy with immediate breast reconstruction and modified radical mastectomy can be chosen individually. For locally advanced breast cancer, neoadjuvant therapy followed by surgery is recommended. Surgery can improve local control and life quality for recurrent and metastatic breast cancer; furthermore, recent evidence also shows some survival benefits. At present, the treatment strategy of breast cancer is surgery-based multidisciplinary approach, and surgery is still the mainstay of treatment no matter in survival and life-quality improving.

Objective To compare the effectiveness and safety of endoscopic polycyclic mucosal resection(EMBM)and endo-scopic submucosal dissection(ESD)in the treatment of esophageal intraepithelial neoplasia.Methods 85 cases of esophageal intra-epithelial neoplasia patients,including 45 cases treated by EMBM and 40 cases treated by ESD.To compare the efficacy,complica-tions,operation time,and medical fees of the two treatment methods by analysis of relevant clinical data.Results Once resection rate of the EMBM treatment group was 97.8%(44/45),and 95.0%(38/40)for the ESD treatment group,there is no significant difference between the two groups(P>0.05);Endoscopy of both treated patients in the postoperative 1,3,6,and 12 months showed no recurrence;The complications incidence of bleeding and perforation of the EMBM treated group(8.89%,0)was significantly lower than that of the ESD treated group(35.00%,15.00%),P<0.05;The average operation time of the EMBM treated group [(26.5±14.2)min]was significantly lower than that of the ESD treated group[(65.2±26.1)min],P<0.05;The total cost of hospitalization of the ESD treated group(18 000 yuan)was significantly higher than the EMBM treated group(8 500 yuan),P<0.05.Conclusion Compared with ESD,EMBM has an easier operation,less complications and patient consuming,and it is suitable for application in primary hospitals.
