Objective To explore the echocardiography characteristics of non-compaction of ventricular myocardium(NVM),and assess its value in the diagnosis of NVM.Methods Philips SONOS 5500 color Doppler ultrasound system with 2-4 MHz transducers was used in 9 patients with NVM.Results In all 9 patients,the presence of multiple trabeculations and multiple deep intertrabecular Space communicating with the ventricular cavity was demonstrated by color Doppler imaging.Both ventricles were involved in 1 patient,only the left ventricle in 7 patients,and right ventricle in 1 patient.Conclusions NVM has typical ultrasonic appearance on echocardiography.It Can find out the NVM manifestations even if patients do not have any symptoms.It is a reliable and convenient way for diagnosing NVM.

OJECTIVE: To explore the changes of serum IgE and tryptase caused by anaphylactic shock rats and discuss the relation to PMI and preservative environment of corpse and specimen. METHODS: Rats were used for establishing anaphylactic shock models and randomly divided into room temperature group, refrigeration group, frozen group, manual hemolysis group, specimen preservation group. And the control group was also established. The blood samples were collected after rats were sacrificed. The degree of hemolysis was graded according to the color of the upper layer of the serum. The mass concentration of IgE and tryptase in each group was detected by ELISA. RESULTS: The levels of serum IgE and tryptase in anaphylactic shock dead rats were higher than that of the control group. Room temperature and frozen made obviously differences on the levels of serum IgE and tryptase with various PMI. The levels of serum IgE and tryptase in refrigeration group showed relatively stable. The levels of serum tryptase and IgE were elevated with differently increasing hemolysis. The levels of serum IgE and tryptase showed no obvious changes during the specimen kept under different temperature conditions for 25 days. CONCLUSION Serum IgE and tryptase obviously increased in anaphylactic shock rats. However, the levels were influenced by PMI and environmental temperature, especially under the conditions of room temperature and frozen.

OBJECTIVETo study the blood pressure (BP) changes in the liver transplant recipients.

METHODSA total of 206 patients without preoperation hypertension received liver transplantation in our hospital from February 2001 to July 2005. The BP level and serum immunosuppressant concentration at preoperation and various time points post operation were determined.

RESULTSCompared with the preoperation, the average systolic and diastolic pressure was significantly increased at the 2 week, 1, 2, 4 and 6 months post operation. The mobility of hypertension increased significantly after liver transplantation, with the highest mobility (46.49%) at the 1st month post operation. There was no linear correlation between the immunosuppressant (FK506) concentration and the BP level at any time point.

CONCLUSIONThere was a high hypertension incidence after liver transplantation. Although the use of immunosuppressive drugs accompanied with the BP increase, there was no linear correlation between the immunosuppressant concentration and the BP level post operation.

Fatal anaphylactic shock is common in forensic practice. However, it is difficult to diagnose for lacking specific pathological and morphologic changes in forensic autopsy. The application of some biochemical indicators is of great significance. This paper reviews the biological characteristics of some biochemical indicators and detection methods. The forensic application, problems and prospects of these indicators are also introduced in details. The stable biochemical indicators, IgE, tryptase and chymase, show great potential and advantages in the identification of fatal anaphylactic shock in forensic medicine.

OBJECTIVEA novel biological piezoelectric ceramic was made by beta-tricalcium phosphate (beta-TCP) and lithium sodium potassium niobate (LNK) piezoelectric ceramics. To study its biocompatibility to osteoblast isolated from the cranium of 1-day-old Sprague-Dawley mice.

METHODSThe biological piezoelectric ceramic TCPLNK1/10, TCPLNK5/5 respectively mixed by beta-TCP and LNK piezoelectric ceramic at the ratio of 1/10 and 5/5. Then osteoblasts were used and seeded respectively on the negative and positive surfaces of TCPLNK1/10 and TCPLNK5/5. Growth and proliferation of the osteoblasts on TCPLNK1/10 and TCPLNK5/5 surfaces were evaluated in vitro by means of scanning electron microscopy (SEM) examination, fluorescence dyeing of osteoblast skeleton protein and MTT assay.

RESULTSCell morphology of osteoblast on positive and negative surfaces of TCPLNK1/10 and TCPLNK5/5 was normal, and both adhesion and growth characteristics showed better than control group. The growing osteoblasts on the TCPLNK1/10 negative surface were significantly higher than others. The negative surface of TCPLNK1/10 possessed better osteogenesis potential than others in vitro.

CONCLUSIONThe surface of TCPLNK may permit the imitation piezoelectric effect of natural bone for bone regeneration.

The aim of this study was to develop a sustained release converse thermosensitive hydrogel for intra-articular injection using chitosan-glycerol-borax as matrix, its physical properties and biocompatibility were investigated. Taking gelation time and gelation condition as index, the influence of concentration of chitosan, ratio of chitosan to glycerol, pH on physical properties of hydrogel were investigated. And then the in vitro drug release, rheological properties and biocompatibility were studied. The thermosensitive hydrogel flows easily at room temperature and turns to gelation at body temperature, which can certainly prolong the release of drug and has good biocompatibility.

OBJECTIVETo probe into the current situation and problems of establishing control group in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder at home.

METHODSTo retrieve the literatures of establishing control groups in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder in magazines at home, and based on key problems in establishment of control group, make a Excel form to take out relative contents in the literatures and classify, summarize and statistically analyze.

RESULTSIn establishing control group in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder, a lot of problems exist, most studies do not have the basis of establishing control group, and also do not establish control group for the purpose of the study, making the whole test have error in the stage of program design, and leading to unreliable for the results of clinical control studies.

CONCLUSIONIn clinical researches of acupuncture and moxibustion, a standard for guiding establishment of control group is eagerly needed.
