Objective To explore the clinical manifestation,physiological index changes and consequences of food poisoning caused by Salmonella weltevreden(S.weltevreden).Methods Bacteria culture and isolation were proceeded with stool specimens from patients who got food poisoning in a university in Chengdu on May 25,2016.Blood routine examination,coagulation function test,C-reactive protein(CRP) and D-Dimer tests were also proceeded with whole blood or plasma samples from food poisoning patients.Results A total of 69 patients were identified food poisoning caused by S.weltevreden,and S.weltevreden was isolated from all of their stools specimens.The common clinical manifestation of these patients were high fever,stomachache and diarrhea with watery stool.91.3% of patients had a blood routine white blood cells(WBC) increasing in different degrees,20.3% of patients had a WBC increasing in stool specimens.The CRP level of all patients were abnormally increased,and the procalcitonin(PCT) level,D-Dimer level and coagulation function were also abnormal.Conclusion The clinical symptoms of food poisoning caused by S.weltevreden are seriously,even physiological function of some patients are changed tremendously or life-threateningly.We should pay attention to the dangers of S.weltevreden to human life in addition to strengthen food safety.

Objective · To clarify effect of adipose stem cells derived conditioned medium (ASCs-CM) on fibrogenesis of dermal fibroblasts costimulated by transforming growthfactor-β1 (TGF-β1), and explore the possible paracrine pathway of ASCs in regulating the dermal tissue rehabilitation.Methods · Co-stimulated by TGF-β1, dermal fibroblasts were treated with different concentrations of ASCs-CM. Variouscellular events including cell proliferation, apoptosis, and mRNA and (or) protein levels of α-smooth muscle actin (α-SMA), type Ⅰ collagen (COL-1) , type Ⅲ collagen (COL-3), hepatocyte growth factor (HGF), basic fibroblast growth factor (FGF-2) were explored. Furthermore, the effect of HGF antibody on apoptosis of fibroblasts caused by ASCs-CM and TGF-β1 were also observed. Results · ASCs-CM inhibited fibroblasts proliferation caused by TGF-β1 and lead to cell apoptosis. α-SMA expression in fibroblasts was attenuated by 10% ASCs-CM +TGF-β1. It was demonstrated that 100% ASCs-CM with TGF-β1 had promoted collagens (especially COL-3) expression in fibroblasts, and increased HGF mRNA level as well. HGF antibody inhibited fibroblasts apoptosis produced by 100% ASCs-CM and TGF-β1. Conclusion · ASCs may have an effect on fibrogenesis of dermal fibroblasts co-stimulated by TGF-β1 through a paracrine way.High concentration of ASCs-CM not only increases collagen production and secretion, but also inhibits fibroblasts proliferation and accelerates apoptosis.

Objective: To observe the application values of 64-slice spiral CT angiography (CTA) in diagnosing persistent trigeminal artery in an effort to improve the understanding of this vascular variation. Methods: The imaging data of 5 patients with persistent trigeminal artery in 2734 patients who performed 64-slice CTA of craniocervical arteries were analyzed retrospectively. The incidence, origin, running, and blood supply from posterior circulation of persistent trigeminal artery, and its complicating other vascular malformations were analyzed. Results: Circled digit oneThe incidence of persistent trigeminal artery was 0.18% (5/2734). Three of them were on the right side and 2 were on the left side. Circled digit twoAll the trigeminal arteries originated from the cavernous segment of internal carotid artery. Four patients were lateral type running and one (20%) was internal type running. According to Saltzman's classification about the blood supply in posterior circulation: one patient was Saltzman type I , one was type II, and three were type III. Circled digit threeThree patients had basilar artery and bilateral vertebral artery hypoplasia at the point of proximal anastomosis, one had complete atrophy of basilar artery at the point of proximal anastomosis, one complicated with aneurysm of the persistent trigeminal artery, and one complicated with fenestrated middle cerebral artery on the contralateral side. Conclusions: 64-slice CTA can clearly, rapidly, noninvasively, and accurately display the persistent trigeminal artery and its running. Understanding of this abnormal vessel in the sellar or suprasellar regions before surgery and interventional treatment will help develop a reasonable surgical and interventional regimen to avoid the risks caused by improper management.

To compare the measurements of axial length by A-scan ultrasound and IOLMaster.For a total of 138 eyes,axial length was measured with IOLMaster followed by contact A-scan ultrasound.Though a great correlation existed between two measurements,the axial length was a little longer with IOLMaster than with A-scan ultrasound.And the difference was statistically significant (P ＜ 0.01).The mean difference of two methods was (-0.198 ± 0.146) mm.With the elongation of axial length,the difference of two methods also increased.For cataract patients with axial length ＞ 28 mm,the control range of crror from IOLMaster for axial length was much lower than that from A-scan.Thus IOLMaster is a simple,fast,reliable and non-contact measurement method of axial length.

The definition of rehabilitation should reflect the connotation and extension of rehabilitation medicine system,moreover,special attention should be paid to the process of translation,applications and promotion due to its derivation from Latin.The fourth edition of rehabilitation medicine textbook which published by People's Medical Publishing House described the definition of rehabilitation inaccurately,although integrated the foreign authority definitions.The definition of ‘ re-learning’has been described by the textbook without considering logical sequence,which caused difficulty in explaining and comprehending between teachers and students in class.Besides,application of another term of rehabilitation medicine in the textbook is imprudence.

This work summarizes the research development and molecular mechanism of Ebp1, a member of the proliferation-associated 2G4 family, in tumor proliferation and invasion. This research serves as a basis and support for further research on the mechanism of tumor proliferation and invasion. The low expression of Ebp1 in various cancers promotes tumor proliferation and invasion. Ebp1 inhibits E2F1, cyclin D1, and cyclin E transcription by interacting with Rb, human histone deacetylase 2, and the transcriptional repressor Sin3A. This inhibition triggers cell cycle arrest and suppresses cell proliferation. Ebp1 also influences cancer invasion and migration. However, the underlying mechanisms remain unknown and require further exploration.

Aim To investigate the effects of breviscapine(Bre)on Na+,K+-ATPase activity of proximal tubule(PT) and its renal protection in early diabetic rats. Methods The rats were divided into three groups: diabetic model (DM group), Bre treatment (Bre group) and normal control (NC group). Rats were administrated with Bre(20 mg?kg-1?d-1, ip) in Bre group, with normal saline(ip) in DM and NC groups for four weeks after diabetes induction with streptozotocin (STZ 65 mg?kg-1, ip) in Bre and DM groups. The urine and blood samples were collected from two intra-ureteral cannulas and the heart, respectively, under anesthesia four weeks after diabetes induction. After one of the renal arteries being perfused, the renal cortex was incubated and PT segments were microdissected freehand under microscope before the Na+,K+-ATPase activity in the segments were assessed by liquid scintillation counter. The blood glucose, levels of creatinine in serum and in urine were assayed. The microalbumin , ?2-microglobulin(?2-MG) of urine and endogenous digitalis-like substance (EDLS) of serum were measured respectively by radioimmunoassay. Results The PT Na+,K+-ATPase activity in NC group was(959.11?117.35) pmolPi?mm-1?h-1, and that in DM group was significant higher for (1893.53?383.90) pmolPi?mm-1?h-1 than it(P
