Objective To assess the radiofrequency ablation (RFA) lesions in canine prostate with real-time harmonic gray-scale contrast-enhanced ultrasonography and investigate the feasibility to predict these lesions.Methods A total of 5 male beagle dogs took RFA of the prostate.Radiofrequency (RF) was delivered under transrectal ultrasound (TRUS) guidance.A lesion was created in the right and left lateral lobes of canine prostate,respectively.The examination of conventional gray-scale ultrasonography,power Doppler ultrasonography,real-time harmonic gray-scale contrast-enhanced ultrasonography were performed immediately after RF procedure.All animals were subsequently sacrificed and the prostates were harvested for pathologic analysis.Thermal lesion volume was calculated based on expected shape of ellipsoid using equation.The volumes of the calculated thermal lesion on contrast-enhanced ultrasonography in dogs were compared with the volumes obtained from the pathological specimens.Results The RFA lesions could not be imaged accurately with real-time conventional gray-scale or power Doppler ultrasonography.However,contrast-enhanced low MI perfusion imaging was able to have real-time monitoring for the lesion (no blood flow).The volume of lesions was measured with contrast-enhanced ultrasonography without significant difference with those of pathologic results.Ultrasonic imaging(conventional gray-scale or power Doppler sonography)of the ablation areas also had its own characteristics.Conclusion The real-time harmonic gray-scale contrast-enhanced ultrasonography appears to be an accurate modality for assessment of RFA lesions.Conventional gray-scale and power Doppler sonography had their own characteristics to evaluate the RFA lesion.

Objectives: To design the mutants of peptide antibiotics hPAB ? based on its molecular structure. Methods: The three dimension structure of hPAB ? was constructed by protein homology modeling method. The mutant molecules were designed and generated by PCR and inserted into pQE CP4 expression plasmid. The recombinant plasmids were identified by PCR and DNA sequencing and then transformed into Escherichia coli JM109 to express target fusion proteins. Results:Peptide hPAB ? shows one ? helical and three ? sheet in its structure. Its ? helical regions seem play a key role in the formation of active oligomer. Aside from positioning Thr 7 and Lys 10 into contact positions, the orientation of the ? helix is conserved about the oligome core, forming a ridge around it. Additionally, the dipoles of the helices would overlap to create a positively charged region near the core. These dipoles may be offset, however, by the presence of Asp 4 at the base of the helix. Two mutant molecules, hPAB ? 38 and hPAB ? 34, were designed by deleting N or/and C terminal 2～5 amino acid residues based on hPAB ? structure. The recombinant plasmids containing the mutants gene can express interest fusion proteins in E. coli JM109 successfully. Conclusions: Design, cloning and expression of the mutants of peptide antibiotics hPAB ? lay down the foundation for screening of the mutant of shorter peptide chain and having high or same antimicrobial activity.

Objective To analyze the clinical manifestations and electroencephalogram (EEG)characteristics of agyria-pachygyria for its early diagnosis,treatment and prognosis judgment in clinical practice.Methods The clinical manifestations and EEG features of twenty-four patients with agyria-pachygyria who were diagnosed by CT or magnetic resonance imaging(MRI) at Pediatric Neurology of Children's Hospital of Chongqing Medical University from July 2004 to July 2013 were retrospectively analyzed.Results Of twenty-four patients,eighteen cases were diagnosed as diffuse agyria-pachygyria and six cases were diagnosed as partial agyria-pachygyria.The clinical features were mainly manifested as mental retardation (twenty-four patients),and motor retardation (twenty-four patients),and epilepsy (eighteen patients).All of the twenty-four patients had abnormal EEG pattern which were mainly three tapes.Type Ⅰ had diffused high amplitude alpha and beta activity in all cortical regions,frontal-central,or parietal-occipital region (fourteen patients).Type Ⅱ showed alternating high amplitude bursts with sharp and slow waves (seven patients).Type Ⅲ was characterized by high amplitude spike or sharp wave activity generalized or multifocal distribution and δ,θ wave mixing graphics (twelve patients).Nine of twenty-four patients showed two or three EEG characteristic patterns in an awake-asleep EEG recording.During the follow-up of 1-8 years old,twelve of the thirteen patients who were diagnosed as epilepsy in diffuse agyria-pachygyria had refractory epilepsy,mainly with infantile spasms or Lennox-Gastaut syndrome.One of the five patients who was diagnosed as epilepsy in focal agyria-pachygyria had refractory epilepsy,mainly for partial epilepsy secondary generalized seizures.There was a significant difference between them (P =0.008).Eighteen of twenty patients who had moderate-severe mental retardation or dyskinesia were diagnosed as diffuse a gyria-pachygyria,while two were focal agyria-pachygyria.Both of them had a significant difference (P =0.005).Conclusions Agyria-pachygyria is a brain malformation caused by neuronal migration abnormality.Diffuse agyria-pachygyria is presented with serious clinical manifestations and poor outcome while the clinical manifestation of focal agyria-pachygyria is relatively mild and epilepsy could be controlled by antiepileptic drugs or epilepsy surgery.These characteristics of EEG patterns along with clinical findings could provide important evidence for early diagnosis,timely treatment and prognosis judgment of agyria-pachygyria.

Objective To identify the common clinical symptoms and signs of pectoral qi insufficiency syndrome;To provide evidence for its clinical treatment.Methods By retrieving 129 medical cases related to pectoral qi insufficiency syndrome in CNKI from January 1954 to October 2013 and Wanfang Database from January 1985 to October 2013, the authors made a statistical analysis of the symptoms and signs in medical cases related to pectoral qi insufficiency syndrome and elementarily generalized the common clinical characterization on pectoral qi insufficiency syndrome under the guidance of the TCM specialists.Results The cardinal syndromes of common clinical manifestation on pectoral qi insufficiency syndrome were shortness of breath and panting on exertion. The concomitant syndromes were pale or dim complexion, lassitude of spirit, lack of strength, shortage of qi and disinclination to talk, inability to sleep, dizziness, dizzy vision, etc. And it commonly superimposed failing to circulation qi-blood of cardiopulmonary as oppression in the chest, chest pain, palpitations, cyanosis, cough, etc, dysfunction of the spleen in transportation and transformation as torpid intake, sloppy stool, abdominal distension, and impairment of qi transformation due to Yang deficiency as cold limbs, fear of cold, edema, inhibited urination, and dry mouth.Conclusion The authors summarized cardinal syndrome, concomitant syndromes and superimposed symptoms on pectoral qi insufficiency syndrome from reported medical cases, which can provide scientific basis for normalizing the clinical diagnosis and treatment and interpreting the scientific connotation of pectoral qi insufficiency syndrome.

In this paper, through a systematic review of literatures on pectoral qi theory, we summarized the defini-tion of pectoral qi, physiological function, deficiency-excess changes, clinical manifestations of pectoral qi deficiency and modern research progress of pectoral qi theory, in order to deepen the understanding of pectoral qi connotation. The connotations of pectoral qi have four major kinds of views. The pectoral qi is a combination of the natural fresh air inhaled by the lungs and the foodstuff essence-qi transformed by the spleen-stomach accumulated in the thorax. The substance of pectoral qi is heart-lung yang qi. Pectoral qi is the special title of acquired essences in the thorax. Pectoral qi accumulated in the thorax is the beating-qi beneath the left breast. Its physiological function includes flowing through the respiratory tract to promote the respiration movement of the lungs, permeating the heart and ves-sels to promote circulation of qi and blood, comprehensively regulating of the heart and lungs, controlling all qi and zang-fu, accumulating body fluids, resisting external evils, controlling mental activities, maintaining mental state healthy and vigorousness, controlling vision, hearing, sound, color, smell and movement, converging primordial qi to maintain the vigor and vitality. Disorders of pectoral qi are mainly manifested as deficiency or excess. Deficiency is mainly manifested in pectoral qi insufficiency, or pectoral qi sinking. Excess is mainly manifested in pectoral qi ob-struction, or pectoral qi counterflow. The common clinical manifestations of pectoral qi insufficiency include short-ness of breath and panting on exertion. The concomitant symptoms are pale or dim complexion, lassitude, lack of strength, shortage of breath and disinclination to talk, insomnia, dizziness, spontaneous sweating, emaciation, darkish tongue with thin and white fur, sunken thin or weak pulse. And it commonly superimposed with failing to circulation qi-blood of heart and lungs as chest distress, chest pain, palpitations, cyanosis, cough, expectoration, and hard stool. Spleen transportation and transformation dysfunction were manifested as poor appetite, loose stool, and abdominal dis-tension. Impairment of qi transformation due to yang deficiency is manifested as cold limbs, aversion to cold, edema, urination difficulty, and dry mouth. In addition, diseases which are treated with pectoral qi are give priority to the heart-lung diseases, and then gradually extend to diseases of other systems. At the same time, there are many reports on using pectoral qi theory in disease treatment. The essence of pectoral qi is also discussed from the perspective of modern medicine. Generally speaking, pectoral qi theory has been put forward early; however, the systematic study is difficult to meet the needs of clinical diagnosis and treatment. There are many problems which remain to be further studied and solved.

Objective Donor derived naive T cells initiated GVHD by contacting with,mesenchymal stem cells(MSC)have been used to prevent or treat graft-versus-host disease(GVHD).although we stiff puzzle about its mechanisms.Observe the effect of MSC on phenotypes of Naive T cell to study the mechanism of MSC immunomodulation. Methods After 3 passages, MSC Was incubated with Naive T cell differentiated from COrd blood CD+34 cells in vitro.Then the variances of naive T cell phenotypes were analyzed by flow cytometric.Results CD+8 T cells were relatively increased after 7 days co-culture with allogenic MSC when compared to control:(35.9±6.3)%VS(18.4±4.5)%.CD+8 CD+3 cells also showed the same trend (27.6±2.8)%vs(15.2±3.1)%.Conclusion MSC may partly reduce the incidence of GVHD by increase of CD+8 naive T cell.The result may provide new clue to explain immunoregulatory mechanism of MSC.

Phospho-histone H2AX(γH2AX) has been widely used in vitro genotoxicity evaluation of ionizing radiation, carcinogenic substances and cigarette smoke as an important biomarker of DNA double stranded breaks ( DSBs) . The study developed an enzyme-linked immunesorbent assay for detection of the content ofγH2AX in cells to evaluate the genotoxicity of cigarette smoke. The study exposed CHO cells with cigarette smoke total particulate matter ( TPM) and cigarette smoke condensate ( CSC) of different dose, dose-effect relationship between smoke exposure and DNA damage and the poisonous difference of cigarette smoke components has been investigated by detecting the content change ofγH2 AX in cells under different exposure time and dose. In addition, reactive oxygen species ( ROS) in cells were also detected to study the mechanism of cigarette smoke exposure induced DSBs. The experiment result showed that the required time for the level ofγH2AX in cells grew to the peak prolonged with increased exposure dose. Once the level of γH2AX in cells grew to the peak value, then it decreased slowly; the level of γH2AX in cells rised with increasing dose of cigarette smoke;The effect of TPM on the content change of γH2AX was more than CSC; Moreover, smoke exposure could induce concentration increase of ROS in cells, and a good correlation of content change of ROS and γH2AX in cells were found, free radicals in cigarette smoke may be one major cause of DSBs.
