A retrospective study involved 110 patients (72 males, 38 females, aged from 1 - 76 years) who underwent surgery for brain abscesses at ViÖt -§øc Hospital from January 1990 to December 1993. 79 patients with brain abscesses were found bacteria in culture. The bacteria were not identified in 31 patients. Results: Rate of bacterial isolation in brain abscesses is quite high. Among these, streptococci make up 37.7%, staphylococci 23.8%, and anaerobic bacteria 17.5%. Streptococci and staphylococci are cause of more than 90% of secondary brain abscesses due to localized infection. Postoperative antibiotics reduced significantly the bacterial isolation rate, comparison with that rate of 87.5% on patients who have not used antibiotics before operation. Rate of recurrence is 7.6% in the patients who were isolated bacteria and 25.8% in the patients who were not identified bacteria.

The records of 75 patients with brain abscesses treated over 7 years were analysed. Congenital cardiopathies were the most frequent causes of abscess. Organisms were identified in 74.07% of the cultures from abcesses speciment. The patients were grouped according to the treatment received: excision (n=42) aspiration (n=33). There were no significant differences is the mortality rates between the two groups. Patients treated by aspiration had a significantly less morbidity than patients treated by excision. Early and aggeressive treatment can result in an excellent outcome in the large majority of patients.

An analysis of 26 patients with brain abscesses treated by abscess ablation has shown that the morbidity rate, complications, relapsed brain abscess, repeated surgery and duration of antibiotic using. The bacteria were isolated in 42% of samples. The abscess ablation was indicated for cases of brain abscess with foreign bodies, brain abscess occurred after cerebrocranial surgery or cerebrocranial injuries. The needle aspiration indicated for cases of brain multiabscess, patients with thalamic perception impairment received needle aspiration in the first stage and abscess ablation in the second stage.

A study on the clinical and paraclinical features and results of treatment of brain multiabscess among 190 patients in Vietduc Hospital during 1992-2002 has shown that the brain multiabscess accounted for 30%. This rate did not depend on the species and bacterial resources. The frequent clinical features were headache, vomiting, fever, hemiplexia and leukocytosis. The effective treatment involved the needle aspiration. The removal operation indicated for located abscesses and meninggeal adjacent abscess.

Acute leukemia is a common malignancy tumor in children. Hemorrhage is one of the common symptoms and causes of death. The abnormality of platelet count, quality and function can cause bleeding. The understanding of platelet function and platelet parameters can provide an important clinical information for children with acute leukemia in evaluating the effect of treatment,the function of bone mar-row and the prevention of bleeding and so on.

Most solid materials in nature consist of minerals, they are ubiquitous on the surface of the earth. After inhaled in body, they will trigger pulmonary disease. The pathogenesis of mineral dusts is always in the way of disputing and consummating. Researcher should pay great attention to the adverse effect of mineral dust in nonprofessional environment. The biological action of mineral surface is an important aspect to discover mineral dust interface function and molecular toxicological mechanism. At present, the superfine mineral dust and nanometer suspending dust are the important components of dust environment safety assessment.

Objective: To assess the value of MRI and single photon emission computed tomography (SPECT) in detecting myocardial ischemia and necrosis. Methods: Coronary angiography (CAG), MRI and SPECT were performed in 28 patients with coronary artery disease one week before revascularization operation. The stenosis criterion was a more than 70% stenosis by CAG; the sensitivity, specificity and accuracy of both MRI and SPECT were calculated according to the criterion. Results: CAG revealed 39 positive arteries and 45 negative arteries. According to the CAG results, the sensitivity, specificity and accuracy of MRI for detecting myocardial ischemia were 92.31%, 80.00% and 85.71%, respectively; and for detecting myocardial necrosis were 66.67%, 91.11%, and 79.76%, respectively. The sensitivity, specificity and accuracy of SPECT for detecting myocardial ischemia were 94.87%, 82.22% and 88.10%, respectively; and for detecting myocardial necrosis were 61.54%, 86.67%, and 75.00%, respectively. Conclusion: MRI and SPECT have high accuracy in detecting myocardial ischemia and necrosis and the results of the 2 methods accord well with each other.

Objective To investigate the clinical effect of ilium grafting combined with Duhuojishengtang on the delay fracture healing and explore the effect on hemorheology. Methods Eighty patients with delayed fracture healing were randomly divided into two groups. Forty patients in control group were treated by ilium grafting and 40 patients in observation group were treated by ilium grafting combined with Duhuojishengtang. The clinical effect was observed after treatment and indexes of hemorheology were recorded after different treatment time. Results The cure rate of observation group was 62.5%, which was significantly higher than that of control group 35.0%, the effective rate of observation group was 92.5%, which was significantly higher than that of control group 72.5% (P<0.01) . There were no significant differences between two groups in indexes of hemorheology after ilium grafting (P>0.05) . After the first, second, third course, the indexes of hemorheology of observation group were better than those of control group, with statistically significant differences (P<0.05) . Conclusions Ilium grafting com-bined with duhuojishengtang can improve the indexes of hemorheology, improve the cure and effective rate and also has high security. It has high clinical value and worth of popularization and application.

Objective To investigate the role of islet B cell dysfunction in the pathogenesis of type 2 diabetes mellitus. Methods FBG and fasting plasma insulin of 49 healthy subjects and 125 first-degree relatives of type 2 diabetes mellitus were determined. HOMA model was used to calculate HOMAIR as an index of insulin resistance and HOMAB as an index of B cell function of pancreatic islet.The insulin sensitivity index(ISI) and early-stage secretion index of islet ?cell(△I_ 30 /△G_ 30 )were calculated. Results The HOMAB and △I_ 30 /△G_ 30 of the group of normal first-degree relatives were higher (P

Urinary calculus is a common disease of urinary system.With the improvement of people's living standard,the incidence rate of urinary calculus increased year by year.Compared with other methods,spiral CT has a great advantage in the diagnosis of urinary calculus.The current commonly used examinations including spiral CT plain scan,low dose spiral CT scan,CT urography,and dual source dual energy CT imaging.The advantages and characteristics of different types of CT are analyzed and compared,which is helpful for clinicians to choose the most proper examination,to make the most of the advantages of various checks,so as to improve the accuracy of diagnosis and effectiveness of treatment.
