Heart fatty-acid-binding protein(H-FABP) is small molecular weight cytosolic protein that is abundant in the heart and has tissue specificity. Concentration of H-FABP changes regulation in serum after the myocardial damage. In addition it has a positive correlation with the degree of myocardial damage. It is an early diagnostic biochemical marker of acute myocardial ischemia. The advance of H-FABP in the research on physiochemical nature,and its application for myocardial injury and prospective study of sudden cardiac death in forensic science were reviews.

OBJECTIVE: Although the therapeutic method of stroke is progressed very quickly in recent years, the incidence of its post-depression is up to 40%. Poststroke depression many affect neural function recovery, for which, to understand it is advantageous of improving living quality of stroke patients.DATA SOURCE: The literatures relevant to poststroke depression were looked up from China medical nuclear journals and studies at home and abroad in recent 5 years on www.google.com, Medline. The Retrieval words: stroke, depression, incidence, relevant factors.STUDY SELECTION: Totally 42 relevant papers were selected on experimental and clinical studies on poststroke depression. The original literatures of non-randomized study were excluded and those of nonblind study were not excluded.DATA EXTRACTION: Of 42 papers, 10 papers were deleted because of repetition of various degrees and 32 papers were sorted out in category and 10 of those were selected as reference.DATA SYNTHESIS: The incidence of poststroke depression is about 40%, resulting from the co-factors of society, psychology and biology.It is viewed generally that the high risk phase of depression is in a couple of year after stroke and the duration of poststroke depression is various. The severity of neural functional deficits in recovery phase is affected by poststroke depression. Moderate and severe depression may delay the recovery of neural function and poststroke depression can also result in poor recovery of daily living capacity of patients, affect patients' cognition and increase the incidence of dementia. Concerning to clinical observation, a remarkable progression has been achieved on treatment of poststroke depression.CONCLUSION: The incidence of poststroke depression is very high,associated with multiple factors. Poststroke depression influences harmfully on neural function, cognition and daily living capacity. Active intervention and treatment provide a certain action on reducing the incidence of poststroke depression.

The pharmacokinetics/pharmacodynamics ( PK/PD) of antimicrobials aims to establish and evaluate dose-concentration-response relationship, and subsequently to describe and predict the effect-time courses resulting from a drug dose.Nowadays, PK/PD is playing an important role in dosage regimen optimizing, reducing toxicity and drug tolerance of antibiotics.And it is also of great significance in determining susceptibility breakpoints and development in new drug.This paper reviews the progress on PK/PD studies of antibacterial and antifungal agents to provide theoretical basis for safe and effective individual dosage regimens.

Objective To explore the effect of responsibility system of family doctors( RSFD) for community management of the patients with diabetic retinopathy ( DR ) .Methods Fifty -two cases with non -proliferative diabetic retinopathy( NPDR) found in annual health examination in community health care centers were selected and randomly divided into intervention group(30 cases) and control group(22 cases).The intervention group received RSFD service mode and the control group received conventional management mode for 1 year.Patients'visual acuity, fundus,fasting blood-glucose(FBG),glycosylated haemoglobin(HbA1c) were observed and compared before and after intervention.Results In this study,the efficacy in improving patients'visual acuity and retinopathy was 73.3%in the intervention group and 45.5%in the control group,there was statistically significant difference between the two groups(χ2 =4.168,P=0.041).Before intervention,the control rates of patients'FBG were 36.4% and 30.0%respectively,and HbA1c was 27.3%and 33.3%.There were no statistically significant differences between the two groups(P>0.05).After intervention,the control rates of patients'FBG and HbA1c were 86.6% and 80.0% in intervention group,and 59.1%and 54.5%in the control group,there were statistically significant differences between the two groups (χ2 =5.147,P=0.023;χ2 =3.861,P=0.049).Conclusion RSFD service mode was conductive to control patients'blood sugar and improve visual acuity and retinopathy,we could disseminate and apply it to manage-ment of DR in community.

Objective To investigate the clinical and electromyographic features of peripheral nerve involvement in MS. Methods The clinical and electromyographic (EMG) data of 29 MS patients were evaluated retrospectively.Results 18 (62.1%) patients showed clinical and/or electromyographic abnormalities of peripheral nerves. The clinical symptoms included extremity numbness in 16 cases (88.9%), limb inertia in 11 cases (61.1%), radicular pain in 5 cases (27.8%), autonomic nerve disorder and dysphagia in few patients. Signs included decrease of tendon reflex in 11 cases (61.1%), periphery or root form hypoesthesia in 9 cases (50%), muscle weakness in 7 cases (38.9%), myatrophy in 4 cases (22.2%), and reduced pharyngeal reflex in 1 case (5.6%). There was no difference in age of onset, course of disease, neurologic impairment and prognosis between the patients accompanied with peripheral neuropathy and the patients without peripheral neuropathy. The electromyographic abnormalities included spontaneous potential in 4 cases (13.8%), increased motor unit potential in 8 cases (27.6%), slow MCV in 15 cases (51.7%), slow SCV in 13 cases (44.8%), low amplitude in 9 cases (31.1%), and prolonged distal latency in 5 cases (17.2%). The neuropathies improved by treatment with corticosteroid in the all patients except one.Conclusions Some MS patients may accompany with peripheral nerve abnormalities, which may improve with the recovery of MS. EMG is useful to evaluale the site and degree of peripheral nerve damage.

Objective To establish the database of diameter and length of the pulmonary artery branches in different phase of cardiac cycle in healthy adult chest MDCT.Methods Normal enhanced chest MDCT with ECG-gating was selected and slab thin slice maximaun intensity projection(STS MIP) reconstruction were performed in different periods on ECG represent systole and diastole respectively.The diameter and length of pulmonary artery on the plane which showed the whole length of the aim artery were measured.Doppler UCG with ECG-gating was performed in healthy adults to measure the inner diameter of pulmonary trunk and right and left pulmonary artery in different phases of the cardiac cycle as contrast method.Results Normal enhanced chest MDCT with ECG-gating showed the diameter in systole period of the main pulmonary artery was larger than that in diastole period,while it went conversely to that of the proximal part of two pulmonary arteries,distal part of the right pulmonary artery,right media-lobe artery,both S10 segmental arteries and the difference were statistic significantly,only the length in diastole period of the right upper lobe artery was larger than that in systole period.The distance between the measured point of the main artery and the right one showed larger in diastole than systole period.On ECG-gating UCG,in addition to that the diameter change of the main pulmonary artery during the two periods were coincident with MDCT,the two pulmonary artery had no significant difference during the two periods.Conclusion It is necessary using branching geometry data of the main artery to segmental arteries in different period of the cardiac cycle with normal enhanced chest MDCT for flowing model building of pulmonary artery.

Objective To study the clinical, histological and immunohistochemical features of breast hamartomas. Methods The specimens were fixed in 10% formalin and embedded in paraffin. The sections were stained with hematoxylin and eosin for histological diagnosis. SP technique was used in the immunohistochemical study.Results We have 8 cases of breast hamartomas with well defined borders microscopically, histologically composed of ducts, lobules, fibrous stroma, adipose tissue. None of the epithelial elements showed any evidence of atypia. Immunohistochemical analysis showed that there was a variable number of epithelial cells showing a nuclear staining for estrogen receptor(ER) in all cases.Conclution Mammary hamartomas are benign tumor like lesions, histologically dissimillar from other breast tumors. It is affected by hormonal factors. The diagnosis is achieved by combining clinical, radiological and pathologic results.
