Objective To investigate the effect of ketamine on the expression of HSP 70 in myocardium in severely burned rats for its possible mechanism of myocardial protection. Methods Seventy-two male Wistar rats were randomly divided into 3 groups: normal control group (group C, n=8), burn injury group (group BI, n= 32) and ketamine group (group K,n=32). 30% Wtal body surface area of Ⅲ degree burn model was developed in group BI and group K. Ketamine 20 mg/kg was injected IM in group K 15 min after the burn model was made. Equal volume of normal saline was given instead of ketamine in group BI. Group C received no treatment. The rats were sacrificed at 3, 6, 12 and 24 h after administration in group BI and group K respectively(8 rats at each time point). Myocardial samples were obtained for determination of the expression of HSP 70 by Western blot analysis. The myocardial ultrastructure was observed at 3 h after administration with electron microscope. Results The myocardial damage was milder in group K than in group BI. The expression of HSP 70 was significantly higher at 3, 6, 12 and 24 h after administration in group K and group BI than in group C(P<0.05).The HSP 70 expression was significantly higher at 3 and 6 h after administration in group K than in group BI ( P<0.05). Conclusion Ketamine can reduce the myocardial injury induced by severe burn through up-regulating the expression of HSP 70 in cardiocytes.

Objective To develop a new methodology of prenatal sonography scoring to assess and dignose clubfoot.Methods Thirty-one fetuses suspected clubfoot(50 foots) and 62 normal fetuses(124 foots) were scanned with both 2D and 3D sonography,and were divided into normal feet group and clubfeet group.Our scoring system was made according to the Pirani-scoring for children,while considering the morphology of mid-foot and hind-foot of infants.The doctors would give final diagnosis for all fetuses after delivery or induced labor,and analyse the correlations among the abnormal signs,sonographic score and the clinical outcomes.Results The curve lat border,the medial crease,the empty heel and the post crease can be observed in the 3D reconstruction images.These four abnormal signs had close correlations with the clinical results.Conclusions The new prenatal clubfeet scoring system by 3D sonography is a promising methodology with clinical values.

This article was aimed to study the relevance between traditional Chinese medicine ( TCM ) syndromes and the treatment of chemotherapy and targeted therapy , in order to provide theoretical support for TCM syndromes of lung cancer in the clinical application . Uniform TCM syndromes questionnaire was used in the TCM syndrome differentiation among lung cancer patients from the Oncology Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine and TCM Department of Shanghai Pulmonary Hospital. The analysis was made on correlation between distribution rules of TCM syndromes and chemotherapy and targeted therapy . The results showed that among primary lung cancer patients , the most TCM syndromes were syndrome of lung-yin deficiency , lung-q i deficiency , blood stasis in lung collaterals , spleen-q i deficiency , lung-yin deficiency with fire excess . There were certain correlation in TCM syndromes and different TCM therapeutic methods , in which targeted therapy had great significant effect on syndrome of lung-yin deficiency ( P < 0 . 05 ) , after targeted therapy syndrome of lung-yin deficiency increased obviously . It was concluded that there were some regulations in TCM syndromes of lung cancer which take syndrome of lung-yin deficiency, lung-qi deficiency, blood stasis in lung collaterals, spleen-qi deficiency, lung-yin deficiency with fire excess. There were certain correlation in TCM syndromes and different TCM therapeutic methods , after targeted therapy syndrome of lung-yin deficiency increased obviously .

Objective To explore the insertion of the teaching contents of nursing in rural doctors'higher education,so as to increase their understanding of medical knowledge and improve their medical skills.Method 90 rural doctors of Grade 2014 were chosen as the research object,and according to their willingness to participate,they were divided into control group and observation group.The students in the control group were mainly taught by the relevant knowledge of clinical medicine,while nursing teaching content was inserted in the teaching of observation group.In the teaching process,firstly,the teaching contents of nursing were reorganized,and then the teaching content of clinical medicine was taken as the main line,according to the development of teaching content,flexibly inserting nursing teaching part.The results of the final examination of the internal medicine of the two groups were compared and the specific learning experience of rural doctors was investigated.SPSS 20.0 was used to analyze the data,the count data was expressed as percentage,and chi square test was performed.Results The number of students in the control group and the observation group whose subjective score was more than 40 was 17.65％ and 48.72％ respectively.The number of students scoring ＜30 points accounted for 23.53％ and 5.13％ of the total number of students,and there was a statistically significant difference between the two groups(P＜0.05).The observation group had a better learning experience,and had little influence on the learning of clinical medical knowledge.Conclusion In the stage of education for rural doctors,inserting the teaching contents of nursing can improve the teaching effect.

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening. Screw tension band technique inherits the traditional advantages of simple manipulation and reliable fixation, also overcomes the disadvantages of early activity limitations caused soft tissue irritation of tension band around knee, the slippage and breakage of internal fixation, and the technique can be popularized generally.

Objective To explore the clinical significance of prenatal diagnosis for absence of fetal cavum septum pellucidum (CSP) by ultrasonography. Methods The ultrasonographic characteristics were retrospectively analyzed in 63 fetuses, whose CSPs were not detected in prenatal two and three dimensional ultrasonography in Nanjing Medical University Affiliated Suzhou Hospital. Results In 63 fetuses with absent CSP, the related malformations included:(1) Five cases were diagnosed as agenesis of corpus callosum (ACC, including four complete ACC and one partial ACC);(2) Twenty-seven cases were diagnosed as holoprosencephaly (HPE, including 18 alobar HPE, ifve semilobar HPE and four lobar HPE);(3) One case was diagnosed as schizencephaly;(4) Two cases were diagnosed as porencephaly;(5) Five cases were diagnosed as hydranencephaly;(6) Twenty-three cases were diagnosed as severe hydrocephalus, among which ifve cases were caused by aqueductal stenosis and the other 18 cases were caused by open spina biifda (Chiari Ⅱ malformation). These absent CSP fetuses had other abnormalities including one case of Dandy-Walker Malformation, one case of Dandy-Walker Variation, 14 cases of median cleft lip, ifve cases of single naris, two cases of proboscis nose, three cases of talipes foot and four cases of single umbilical artery, etc. These 63 cases were all followed up after prenatal ultrasonography but 4 cases were missed and one case of septo-optic dysplasia was misdiagnosed as lobar HPE. The diagnoses of other 58 fetuses by ultrasonography were conifrmed by follow up. Conclusions CSP is considered as an essential part in prenatal evaluations of the fetal central nervous system during second-and third-trimester. Absence of CSP is always accompanied with an extremely wide spectrum of fetal neuroanatomic malformations, including prosencephalon diseases, intracranial midline anomalies, etc. Prenatal ultrasonography is the best choice for the observation of CSP.

Objective To evaluate the bone healing effect of vascularized tissue-engineered bone induced by endothelial progenitor cells(EPCs)in repair of large segmental radius defects in rabbits.Methods A total of 68 healthy New Zealand white rabbits were enrolled in the study and randomized into three groups,ie,experimental group(EPCs group):EPCs plus bone marrow mesenchymal stem cells (BMSCs)plus decalcified bone matrix(DBM);control group:BMSCs plus DBM;sham control group:pure DBM.Materials mentioned above were implanted into middle radius defects for 15 mm.At 12 and 16 weeks post-operatively,X-ray test,bone mineral density test,histological light microscopic test,osteocalcin immunohistochemical staining test and biomechanical test were carried out.Results Growth and plasticity of callus,speed of medullary cavity recanalization,bone healing speed and biomechanical intensity in the experimental group were all significantly better than those of control group.Conclusions Vascularized tissue-engineered bone induced by EPCs has strong osteegenic ability,can accelerate bone healing and hence is an effective method for repair of large segmental bone defects.
