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.

BACKGROUND: Finite element method has become an important means for biomechanical study against sideways falls because of its unlimited sample size, small experimental error and good repeatability.OBJECTIVE: To establish three-dimensional normal pelvis and brace-covered pelvis models and then to analyze the stress, strain and displacement distribution during sideways fall and to verify the effectiveness of hip brace.METHODS: Digital human Abaqus 6.51 software was used to build three-dimensional normal pelvis and brace-covered pelvis models. The rigid constraint surface was fixed. The whole pelvic model was loaded with 2 m/s loading. The stress, strain and displacement variation with time and contours were detected prior to and after wearing the hip brace. RESULTS AND CONCLUSION: Compared with the normal model, the contact force between the pelvis and the ground, the maximal compression strain of the cancellous bone when the maximal contact force between the pelvis and the ground generated, the maximal strain of the greater trochanter and femoral neck, the maximal von-Mises stress of the greater trochanter and femoral neck, and the mean stress of the greater trochanter and femoral neck were significantly reduced in the brace-covered pelvis model during sideways falls. These findings indicate that the hip brace can play a protective role in the greater trochanter, and effectively reduce the incidence of intertrochanteric fractures during sideways fall.

Objective To explore the application of serum dust mite specific IgE detection in the diagnosis and treatment of child asthma .Methods 52 children cases of asthma in this hospital from February 2008 to April 2010 were selected as the observation group ,11 cases were <3 years old ,18 cases were 3- < 7 years old and 23 cases were 7- <12 years old ;44 healthy children were taken as the control group ,8 cases were <3 years old ,16 cases were 3- < 7 years old and 20 cases were 7- <12 years old .The two groups were detected the serum dust mite specific Ig E .Results The serum dust mite specific Ig E was (152 .78 ± 48 .95) U/mL in the observation group and (25 .62 ± 6 .49) U/mL in the control group ,the serum dust mite specific Ig E concentration in the observation group was significantly higher than that in the control group ,the difference showed the statistical significance (P<0 .05) .Conclusion The positive rate of serum dust mite specific IgE in child asthma is very high ,especially the children patients of 7- <12 years old have the highest positive rate .Therefore ,the dust mite allergen is the important factor inducing child asthma .The detection of serum dust mite specific IgE is conducive to find the dust mite allergen ,which is an important measure for preventing and treating child asthma induced by the dust mite allergen and is worthy of being promoted in clinic .

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.

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 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

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.
