RESUMEN
Objective To study the clinical features of patients with scrub typhus and provide scientific basis for clinical diagnosis and treatment. Methods Clinical data of patients with scrub typhus in the First Affiliated Hospital of Kunming Medical University from January 2016 to December 2016 were collected. Epidemiological data, clinical manifestations, laboratory findings, image examination results, treatment and outcome were retrospectively analyzed. Results The clinical manifestations included 59 cases (100.0％) with fever, 44 cases (74.6％) with headache, 39 cases (66.1％) with chills, 34 cases (57.6％) with muscle and joint pain, 29 cases (49.2％) with prostration, 49 cases (83.1％) with eschar or ulcer, 42 cases (71.2％) with lymphadenectasis, 23 cases (39.0％) with hepatosplenomegaly. Laboratory test results: 51 cases (86.4％) had normal or elevated white blood cell count, 50 cases of eosinophil reduced (84.7％), 27 cases of blood platelet (PLT) reduced (45.8％), 33 cases of albumin reduced (55.9％), 50 cases of alanine aminotransferase (ALT) increased (84.7％), 48 cases of aspartate aminotransferase (AST) increased (81.4％), and 56.1％ (23/41) of the patients with triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3) and free thyroxine (FT4) levels significantly lowered, with predominantly free FT3 reduction (82.6％,19/23); C reactive protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR) and ferritin were increased in 93.9％(46/49), 35.4％ (17/48), 64.9％ (24/37), and 83.8％ (31/37) of the patients, and 95.6％(43/45) was accompanied with chest radiographic abnormalities. Tetracycline, doxycycline and azithromycin treatment were all effective. Conclusions The clinical manifestations of patients with scrub typhus, involving multisystem, are diverse and thyroid hormones decrease is observed. Early diagnosis and treatment is the key to improve the prognosis of patients with scrub typhus.
RESUMEN
Liver fibrosis is a pathological process for the liver to repair various chronic liver injuries and may eventually progress to liver cirrhosis,liver failure,or even liver cancer.Therefore,early intervention arid treatment of liver fibrosis is of particular importance.This article summarizes the latest research advances in the roles of TGF-β/Smad signaling pathway,Notch signaling pathway,Wnt signaling pathway,Hedgehog signaling pathway,and integrin signaling pathway in the pathogenesis of liver fibrosis and points out that these signaling pathways play an extremely important role in the development and progression of liver fibrosis and may provide new directions for the treatment of liver fibrosis.
RESUMEN
Objective To compare the clinical outcome of intramedullary nail with locking plate in the treatment of two-part proximal humerus fractures.Methods PubMed,SpringerLink,EMBASE,The Cochrane Library,Medline,Science Direct,CNKI,Wanfang Data and VIP database were searched for relevant studies comparing intramedullary nailing and locking plate fixation of two-part proximal humerus fractures.A meta-analysis of the two methods was conducted using the RevMan 5.0.Differences between the two methods were compared with respect to operation time,intraoperative bleeding,bone union time,Constant score and postoperative complication incidence.Results Seven studies were included in the meta-analysis,with 136 patients treated with intramedullary nail and 159 patients treated with locking plate.Intramedullary nailing showed advantages over locking plate fixation with regards to operation time (WMD =-27.71,95％ CI-36.07--19.35,P ＜ 0.05),intraoperative blood loss (WMD =-114.18,95％ CI-169.91--58.45,P ＜ 0.01) and bone union time (WMD =-2.91,95％ CI-5.80--0.01,P ＜ 0.05).While the two methods showed no significant differences in Constant score (WMD =-2.84,95 ％ CI-5.90--0.22,P ＞ 0.05) and postoperative complication incidence (OR =0.89,95％ CI 0.43-1.84,P ＞ 0.05).Conclusion Intramedullary nail is superior to locking plate in operation time,intraoperative blood loss and bone union time for the treatment of two-part proximal humerus fractures,but the two methods are similar in Constant score and postoperative complications rate.
