Journal of Chongqing Medical University 2007;0(08):-
Objective:To investigate the Acinetobacter baumannii’s distribution feature、the antimicrobial resistance of Acinetobacter baumannii isolated during the past 4 years and compare antibacterial activity of Polymyxin B against multidrug-resisitant(MDR) Acinetobacter baumannii with that of Imipenem in vitro.Methods:The distribution feature of infection caused by Acinetobacter baumannii was supervised.Disk diffusion test was used to study the antimicrobial agents resistance of Acinetobacter baumannii and transition of drug resistance.The results were evaluated based on Clinical and Laboratory Standards Institute(CLSI).The MDR Acinetobacter baumannii were screened by WHONET 5.MICs(minimal inhibitory concentration)of Polymyxin B and imipenem were detected by broth dilution method.Results:Constituent ratio of infections caused by Acinetobacter baumannii had been incresed in the recent 4 years,especially in intensive care unit.Although carbapenems were the most active antibiotics tested against Acinetobacter baumannii,the resistance rate had been sharply raised since 2008.In addition,the ratio of MDR Acinetobacter baumannii had also been raised in the 4 years.The results of MIC displayed that Polymyxin B had the higher antibacterial activity against the MDR Acinetobacter baumannii than Imipenem. Conclusion:Proportion of nosocomial infection caused by Acinetobacter baumannii significantly increased.The resistance rate of Acinetobacter baumannii had been rised obviously and the number of MDR Acinetobaeter baumannii had been increased sharply. Monitoring of the antimicrobial agents resistance to Acinetobacter baumannii should be strengthened.Polymyxin B still shows strong antibacterial activity on the MDR Acinetobacter baumannii in vitro.We can consider using Polymyxin B to treat the severe infections caused by MDR Acinetobacter baumannii.

Objective To investigate the low doses of 131 iodine on serum Ghrelin levels and serological related indexes in pa‐tients with hyperthyroid .Methods A randomized controlled trials ,96 cases of hyperthyroidism in our hospital were randomly divid‐ed into two groups (group A and group B)according to the ratio of 1∶1 from June 2011 to June 2012 ,48 cases in each group ,and at the same time ,42 cases health people as health control group .The group A were treated with 131 iodine solution 3 .69 -4 .40 MBq/g reatment ,group B was given 131 iodine solution 2 .59-2 .96 MBq/g treatment ,and the serum Ghrelin levels and serological related indicators of two groups patients were statistically analyzed after treatment .Followed up for 2 years ,review of the serum levels of Ghrelin and serological related indexes and compare the incidence of hypothyroidism .Results The serum FT3 ,FT4 and FPG levels of hyperthyroid patients were significantly higher than the health control group (P< 0 .01);conversely ,the serum S‐TSH and Ghrelin levels of hyperthyroid patients were significantly lower than the health control group (P<0 .01) .3 months later after treatment ,the serum FT3 ,FT4 and FPG levels of the hyperthyroidism group B were significantly lower than hyperthyroidism group A(P<0 .05);on the contrary ,the serum Ghrelin and S‐TSH levels were significantly higher and hyperthyroidism group A (P<0 .05);2‐year follow‐up after treatment ,the incidence of hypothyroidism of hyperthyroidism group A were higher and group B ,but without statistical significance(P>0 .05) .Conclusion A low dose of oral 131 iodine solution (2 .59‐2 .96 MBq/g) ,could get a better short‐term efficacy in patients with hyperthyroidism ,high security .
3.Research progress of ovarian cancer apoptosis related factor-Survivin and Smac
Journal of International Oncology 2015;(4):313-315
Survivin is the strongest member of the inhibitor of apoptosis protein(IAP)family. Smac is the second mitochondria-derived activator of cysteine proteases,which can promote apoptosis by combining with IAP. Abnormal expression of them is closely related with occurrence,development,treatment tolerance and prognosis of ovarian cancer. It is prompted that Survivin and Smac are expected to play important roles in the early diagnosis and targeted therapy of ovarian cancer.

Chinese Journal of Radiology 2000;0(11):-
Objective To evaluate the value of apparent diffusion coefficients (ADCs) in the diagnosis of malignant bone neoplasms.Methods Eighteen cases with consecutive primary malignant bone neoplasms of the knee were prospectively enrolled in the study. Each patient had a controlled preoperative MRI including a SSEPI-DWI sequence. With the help of a pathologist, spatially localized histological sampling study of the postoperative specimens was performed. ADCs of viable tumor (intra- and extraosseous part), peritumoral edema (including soft tissue edema and intramedullary edema), and tumor necrosis of the neoplasms confirmed by spatially localized histological sampling or following up were calculated and compared.Results Mean ADCs of viable tumor, peritumoral muscle edema, peritumoral marrow edema, tumor nerosis, normal muscle, and normal marrow were (1.181?0.236)?10 -3mm2/s (intraosseous part)/(1.158?0.259)?10 -3mm2/s (extraosseous part), (2.347?0.233)?10 -3mm2/s, (1.997?0.119)?10 -3mm2/s, (2.230?0.208)?10 -3mm2/s, (0.486?0.313)?10 -3mm2/s, and (0.483?0.288)?10 -3mm2/s, respectively. Statistical differences were significant among all these tissues (F=153.131, P=0.000). The ADCs of viable tumor were higher than that of normal tissues (P
