Objective We characterized the clinical features of sporadic Creutzfeldt-Jakob disease(sCJD)in or?der to diagnose it at the early stage. Methods Seventeen patients with sCJD were enrolled in the study. The clinical data, symptoms at the early stage, result of auxiliary examinations and survival time were analyzed. Results The ratio of male to female was 1:1.83 and the average age of onset was 60 ± 8.8 years old. Most of them presented with walking unstable (82.4%)and hypomnesia (64.7%) as the initial symptom. The occurrence rate was 82.4%, 76.5%and 58.8%for myoclo?nus, colored-ribbon-shaped high signals in cerebral cortex and high signals in basal ganglia of MRI. Periodic synchro?nous discharge (PSD) of electroencephalography(EEG) was seen in 82.4% cases, while cerebrospinal fluid analysis re?vealed positive results for 14-3-3 protein in 70%cases. Twelve patients had been dead in our study. The median surviv?al time was 12±7.7 months. Conclusions sCJD is more frequently occurred in mid-aged and older without specific symp?toms in early stage and positive rate of high signals in cerebral cortex of MRI and PSD of EEG is high.

Objective To seek a method to correct the bent cartilaginous vault.Methods This study included 18 patients (12 women,6 men,aged 18-45 years) suffering from the bent cartilaginous vault with the various degrees of nasal obstruction from January 2005 to December 2009.A open surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the dorsum or nasal tip.The approach depended on full mobilization of deviated cartilage,removal of the deviated part of the quadrangular cartilage,followed by straightening of a caudal septal extension graft and its fixation in the corrected position.Rhinoplasty was performed to correct bent cartilaginous vault.Results A satisfactory result was gained in all clinical cases,except a septum still to remain light tilt (not affect the breathing function).Follwing-up for 3-24 months,all cases dorsum of nose was straighten and nasal septum situated mediately.All patients indicated cosmetic satisfaction of nasal dorsum and tip and improvement in nasal obstruction.No nasal deformity and septum tresis was found in all patients.Conclusions ()pen rhinoplasty is a helpful technique in the treatment of the bent cartilaginous vault.Septal surgery is necessary in the patients with cartilage framework,not only to improve breathing but also to achieve a straight,symmetrical and external nose as well.

Objective To analyse the clinical features of pelvic insufficiency fractures (PIF) in patients with cervical cancer after radiotherapy and explore the risk factors affecting its occurrence .Methods 55 cases of patients with cervical cancer that used radia-tion therapy as a single treatment were chosen in our hospital from February 2007 to May 2010 and the clinical features were ana-lysed;The fractures of spine ,sacrum ,sacroiliac joint ,ilium and pubis and femoral were observed and the density of fifth lumbar (L5 ) vertebrae ,left and right sacrum were detected via the CT or MRI (Hounsfield Unit)after 2-year follow-up ,the different factors on the incidence of PIF were explored .Results 12 cases (19 sites) of patients in 55 patients occured PIF after follow-up 2years ,the cumulative incidence was 21 .82% ;the distribution of PIF parts were followed :lumbar vertebrae had 5 cases ,sacral had 5 cases ,pu-bis had 4 cases ,sacroiliac joint had 2 cases ,iliac had 2 cases and femoral head had 1 case .The incidence rate of PIF that density of fifth lumbar vertebrae was ≤130 HU and >130 HU were 16 .36% and 5 .45% respectively ,the PIF′incidence rate that density of left side of sacrum was≤ -35 HU and > -35 HU were 18 .18% and 3 .64% respectively ,the incidence rate of PIF that density of right side of sacrum was ≤ -35 HU and > -35 HU were 20 .00% and 1 .82% respectively ,the density of the three parts all had statistical difference on the incidence of PIF (P<0 .05) .Univariate analysis showed that menopausal status and the average density of CT had statistical effects on PIF (P<0 .05);Multiple analysis showed that the average density of CT was the independent factors affecting PIF′incidence after radiotherapy .Conclusion The patients with cervical cancer may occur pelvic insufficiency fracture af-ter radiotherapy ,and its incidence is related to menopausal status and bone mineral density .

Acute respiratory distress syndrome (ARDS) is a common diseases in critical ill patients, which is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. And it can be divided into two phases in pathophysiology: an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibro proliferative phase. The early prediction and risk assessment of patients with ARDS is still very poor in the clinical. In recent years, researchers gradually focus their research on exploration of biomarkers of ARDS. The article mainly aims to sum up the development of biomarkers exploration.

Objective To primarily explore the efficacy and adverse effects of the combination of fiudarabine,cytarabine and granulocyte colony-stimulating factor(G-CSF)(FLAG regime)therapy for relapsed and refractory acute leukemia in children.Methods Ten children were treated with the FLAG regime for relapsed and refractory acute myeloid leukemia (AML)and acute lymphoblastic leukemia(ALL)from Feb.2007 to Mar.2010.There were 8 male and 2 female,with mean age 8 years(ranging from 4 to 12 years).AML was diagnosed in 8 children,AML-M2 in 5 cases,AML-M4 in 3 cases.ALL was diagnosed in 2 children,both were B-ALL.Six children had refractory disease,and 4 cases were in relapse.FLAG regime included:fludarabine 25 mg?m-2?d-1,days 1-5;cytarabine 2 g?m-2?d-1,days 1-5;G-CSF 150-300 ?g?d-1,from day 0 to neutrophils ≥0.5?109 L-1.Results Complete remission was obtained in 6 children(60%),partial remission was obtained in 1 child(10%),and 3 children were considered non-response(30%).The total effective rate was 70%.For 8 children with AML,6 children had achieved complete remission(75%),2 children had non-response(25%).While in children with ALL,1 child got partial remission,and the other one had non-response.Myelosuppression and infections due to neutropenia were the most frequent adverse effects,severe nonhematologic toxicity were not observed in these children.And there were no chemotherapy-related death.Conclusions The FLAG regime is effective in treatment of children with relapsed and refractory acute leukemia,especially for the children with the relapsed and refractory AML.The adverse effects from this regime were well tolerated.FLAG regime can give children with relapsed and refractory acute leukemia another chance.

Animal medicines mainly contain protein which was organic molecule with quaternary structure and had the property of thermal denaturation. When suffering from heat for a consistent time, the native conformation of protein would be destroyed. After denaturation the biological activity of protein will lose and some physicochemical and biochemical properties will be changed. Leech was a classical animal medicine in the views of traditional Chinese medicine (TCM) which had the functions of breaking stagnant and eliminating blood stasis. In the usage history, it was processed for a long time. No matter stir-frying leech with talc powder embodied in Chinese Pharmacopoeia or stir-baking with wine as a distinctive method in Beijing district, the process procedure was basically performed under high temperature. The purposes and intentions of process are mostly limited to technology conditions at specific historical period. In this article, based on existing processing procedure and its character of Leech, the changes of active components and pharmacological activities before and after processing under high temperature were summarized. The results demonstrate that the protein of leech would be denaturated; some active peptide such as hirudin were partly or totally destroyed; some toxic mineral elements, such as Pb, Hg, Cd, were decreased; at the same time, heating can promote some chemical components transforming into hypoxanthine which had the function of antihypertensive, antiasthmatic and antalgic. Consequently, after processed under high temperature, the purpose of decreasing toxicity and alleviating the strong property was achieved. Pharmacological changes of leech processed under high temperature were mainly manifested in the anticoagulant and antithrombotic activity, etc. Based on current processing research status about animal medicine leech, future research methods and directions on scientific connotation of leech processed under high temperature were put forward in this article.
