Objective To analyze the clinical characteristics of severe fever with thrombocytopenia syndrome (SFTS) so as to improve the recognition of the emerging infectious disease.Methods A retrospective analysis was performed upon clinical manifestations,laboratory test results and prognostic features of 169 patients with SFTS admitted to the 154 Hospital,Chinese People's Liberation Army from October 2010 to May 2011.The patients were divided into moderate disease group and severe disease group according to the prognosis.The differences between two groups were compared to explore the prognostic indicator of severe type.Results All patients with SFTS inhabited in hilly ground with history of field work.The main clinical symptoms were severe fever (98.8％,167/169),headache (52.1％,88/169),muscle soreness (95.9％,162/169),nausea (73.4％,124/169),vomiting (67.5％,114/169),coughing (61.5％,104/169),etc.Superficial lymph node enlargement with haphalgesia was observed in 45.0％(76/169) patients.Petechia or ecchymosis was observed in 36.7％ (62/169) patients.Critical patients were mainly aged ＞ 60 years,associated with nerve and circulatory system syndrome,prominent hemoptysis,dyspnea,and nearly 73.3％ (22/30) of severe thrombocytopenia.Serum levels of aspartate aminotransferase,creatinine and urea nitrogen were significantly higher in severe disease group than those in moderate disease group [235 (47-1750) U/L vs 88 (14-2000) U/L,997 (281-2601) U/L vs 399 (26-2633)U/L,101 (62-291) μmol/L vs 70(26-205) μmol/L,7.0(2.2-20.0) mmol/L vs 4.8(1.4-18.5) mmol/L,all P values ＜0.001].Conclusion Nerves system syndrome,transaminase and urea nitrogen are risk factors of prognosis of severe SFTS to whom deserves paying attention.

A 34-year-old male patient with suspected pheochromocytoma was referred to our department for paroxysmal hypertension. Pheochromocytoma was confirmed by very high plasma nor-metanephrine ( NMN ) and metanephrine ( MN ). Contrast CT of the adrenal disclosed a 3.0 cm x 3.0 cm mass in the left adrenal. 18 F-FDG-PET-CT showed high uptake only in the left adrenal. When the patient's blood pressure was well controlled with 4 mg/d doxazosin for 2 weeks, surgery was then performed under laparoscopy. A round solid left adrenal pheochromocytoma was resected. After surgery, plasma MN and NMN levels returned to normal, and the patient was free of clinical symptoms with normal blood pressure. This patient has been followed 3 years with normal blood pressure, MN, and NMN levels, without tumor recurrence shown hy adrenal CT.

Aim To investigate the role of chemokine-like factor 1 ( CKLF1 ) in SH-SY5 Y cell migration and its molecular regulatory mechanism. Methods SH-SY5Y cells were stimulated with CKLF1 for 0. 5 h, 2 h, 8 h and 24 h, respectively. The migration distance and the percentage of migration cells were recorded by CELLocate analysis. The phosphorylation of focal ad-hesion kinase ( FAK) at Tyr-397 site was detected by Western blot analysis. By chemotaxis assays, we con-firmed the chemotaxis of CKLF1. Furthermore, FAK inhibitor PF-573228 and PLCγ inhibitor U73122 were used for the research of molecular regulatory mecha-nisms involved. Results CKLF1 promoted cell migra-tion and induced a strong increase in the phosphoryla-tion level of FAK-pY397 , which were significantly at-tenuated by the presence of U73122 ( a specific inhibi-tor for PLCγ) . In addition, the chemotaxis of CKLF1 was obviously blocked by the FAK inhibitor PF-573228 . Conclusion CKLF1 induces SH-SY5 Y cell migration via PLCγ/FAK signaling pathway.

OBJECTIVE To analyze the resistance of Pseudomonas aeruginosa (PAE) isolated from clinical specimen and provide the guidance for the clinical treatment. METHODS The P. aeruginosas infection status from Jun 2005 to Dec 2007 was reviewed retrospectively,and the results of susceptibility test in 286 strains of PAE were analyzed. RESULTS The drug-resistance rates to gentamicin,cefotaxime,and ceftriaxone in PAE were all above 60.0%,and that to cefoperazone/sulbactam,piperacillin/tazobactam sodium,amikacin and levofloxacin showing all higher sensitivity. The resistance rates to meropenem and imipenem were 17.1% and 18.5%,respectively. CONCLUSIONS P. aeruginosa is one of the main pathogenic bacteria in nosocomial infection. It's very important to strengthen the monitoring of drug-resistance of PAE and rationally antibiotics usage.
