Objective To show the distinctive resonance pattern in 7 cases of intracranial abscess and 19 cases of cystic lesions as to evaluating these specific resonance peaks. Methods Characteristics of ~1H-MRS in 7 patients with brain abscesses and 19 with cystic or necrotic intracranial tumors were analyzed and compared. Peak assignment was based on reference values from in vivo and in vitro studies. Results Among 7 patients with brain abscesses, 6 showed the presence of cytosolic amino acid (AA) at 0.9 ppm, 5 showed alanine (Ala) at 1.5 ppm, 2 showed acetate (Ac) at 1.9 ppm and 1 patient showed succinate (Suc) at 2.4 ppm. None of the above resonances had been detected in spectra from 19 cases of cystic or necrotic intracranial tumors. Conclusions ~1H-MRS might reflect the different histochemical specificity of abscesses and cystic or necrotic tumors effectively. It should have special values in diagnosis and differential diagnosis of the brain abscess.

Diffusion tensor imaging (DTI)can reflect the brain structure and development more quantitatively and intuitively than conventional magnetic resonance sequence by obtaining the diffusion properties of water molecules. In neonatal brain developmental research,DTI could be used to study the developmental regularities of white matter tracts and cerebral structure deformity.It can also help to explore the relationship between white matter microstructure and neurodevelopmental outcome.In the study of brain injury,including premature white matter injury,hypoxic ischemic encephalopathy,neonatal stroke,and so on,DTI can diagnose the brain microstructure injury precisely,evaluate the ef-fectiveness of interventions and predict the long -term neurodevelopmental outcome.DTI may have good prospect in re-search and clinical application on neonatal brain development and injury.

OBJECTIVE To investigate and analyze the incidence and related factors of nosocomial infection in old inpatients with cancers during radiotherapy and chemotherapy.METHODS Retrospective surveys of nosocomial infection were carried out in 236 old inpatients with cancers from Jan 2005 to Oct 2008.?2 Test was used to evaluate the difference significance of the data.RESULTS The surveys indicated the infection rate was 44.36% and without the sex difference.The infection rate among old inpatients with lung cancer was the highest and counted for 69.39% and then with radiotherapy and chemotherapy that was 56.96%.Respiratory infection was the main infection and counted for 51.27%.The hospital stay time correlated well with the infection rate of the inpatients.With the hospital stay time increasing,the infection rate also increased.Moreover,the predisposing factors of inpatients infection included poor nutrition,advanced stage of tumors,aggressive procedures,leukopenia and application of antibiotics.CONCLUSIONS The nosocomial infection rate of old inpatients with cancers during radiotherapy and chemotherapy is much higher than that of the elders with common diseases and that of the youngers with cancers.The incidence of nosocomial infection is related to the sites of the primary cancers,therapy methods,hospital stay,etc.We must emphasize and control the predisposing factors effectively,and reduce the occurrence of nosocomial infection.

Objective To investigate the current status and influencing factors of compassion fatigue in nurses. Methods A total of 477 nurses from 4 hospital in Tianjin were investigated with the self-designed demographic questionnaire, Compassion Fatigue Scale, Practice Environment Scale and General Self-Efficacy Scale. Results The mean score of compassion fatigue, practice environment and general self-efficacy were showed respectively as following: (2.70 ± 0.34), (2.99 ± 0.49) and (2.42 ± 0.63) points, which indicated at a moderate level. Single factor analysis found that marriage, age, nursing age, department had statistically significant influence on compassion score of nurses(P<0.05). Multiple regression analysis showed that nursing age, nursing foundations for quality of care, staffing and resource adequacy, nurse manager ability, leadership and self-efficacy were indicated as predictive factors of compassion fatigue among nurses. Conclusions Clinical nurse have compassion fatigue which can be influenced by nursing working environment and self-efficacy. So compassion fatigue could be prevented by improve working environment and enhance personal ability.

Objective To provide the nurse care evidence of nutritional intervention in patients with lung cancer during radiotherapy and chemotherapy by analyzing the nutritional status of these patients.Methods 55 patients with lung cancer who received chemotherapy and radiotherapy were selected.The nutritional status of these patients were evaluated by laboratory examination data at the time of hospitalized,ongoing and the end of radiotherapy. Results The hemoglobin(Hb),albumin(ALB),body mass and body mass index(BMI)were (130.50 ±17.80)g/L, (41.02 ±5.68)g/L,(61.29 ±8.75)kg,(22.36 ±2.78)kg/m2 respectively at admission;(115.90 ±19.00)g/L, (37.94 ±5.55)g/L,(59.95 ±9.05 )kg,(21.86 ±2.86)kg/m2 respectively during the course of radiotherapy;(110.40 ±19.40)g/L,(36.91 ±5.30)g/L,(58.91 ±9.30)kg,(21.48 ±2.99)kg/m2 respectively at the end of radiotherapy.At different stages of radiotherapy,the nutritional index gradually decreased,the Hb was lower in the middle of the radiotherapy than on admission,the difference was significant(t =8.611,P <0.05).The Hb in the late stage of radiotherapy was lower than the middle,the difference was significant(t =2.492,P <0.05).Although the ALB in the latter stage of radiotherapy was lower than the middle,but the difference was not statistically significant (t =1.464,P >0.05),and the difference was significant compared with on admission(t =4.815,P <0.05).The weight of the patients in the middle period of radiotherapy was less than the time of admission,but the difference was not statistically significant(t =0.781,P >0.05).The weight of patients in the late stage of radiotherapy was lower than the medium term,but the difference was not statistically significant as well(t =0.601,P >0.05),and there was no significant difference compared with on admission(t =1.382,P >0.05).The BMI of the patients with radiotherapy was lower than that at the time of admission,the difference was not statistically significant(t =0.091,P >0.05).The BMI of patients with radiotherapy was lower than that in the medium term,whereas the difference was not statistically significant(t =0.690,P >0.05),and the difference was not statistically significant compared with on admission(t =1.599,P >0.05).The Hb (F =16.643,P =0.000)and ALB(F =7.736,P =0.001)decreased significantly in particular.Conclusion The risk of malnutrition in patients with lung cancer is exist during radiotherapy and chemo-therapy,and it is obvious in the middle -late stage,the changes of physical and biochemical indexes have been appeared,and among them,Hb and ALB are the most obvious,so should be monitored and managed cause these data varied significantly.

Objective:To evaluate the association of glutathione S-transferase M1 (GSTM1 )polymorphism,smoking and alcohol drinking with oral cancer susceptibility in Asians by meta-analysis.Methods:A literature search of PubMed,Chinese BioMedical, Wanfang,VIP and CNKI databases from inception to July 30th,2013 was conducted.Crude odd ration (OR)with 95% confidence intervals (95%CI)was calculated.Results:27 case-control studies were assessed,and the results showed that the association be-tween GSTM1 null genotype and oral cancer susceptibility was significant in Asians (OR=1.31,95%CI:1.18-1.45,P<0.001), especially in South Asians (OR=1.35,95%CI:1.20 -1.52,P<0.001).Significant associations between oral cancer risk and smoking and alcohol drinking were found in East Asians (Smoking:OR=1.70,95%CI:1.36 -2.13,P<0.001;Alcohol drink-ing:OR=1.54,95%CI:1.24 -1.90,P<0.001).Conclusion:GSTM1 null genotype may be associated with increased oral cancer risk in Asians.Smoking and alcohol drinking confer significant susceptibility to oral cancer in East Asians.

The study is to prepare taste masking and enteric-coated clarithromycin granules by melting and fluid bed coating technology. Clarithromycin and matrix materials were melted at a certain temperature, and then made into particles by fluidized bed coating. X-ray powder diffraction and scanning electron microscopy were used to identify the crystal and morphology of drug loading granules. In vitro dissolution method was used for the observation of the drug release behavior. The results showed that the drug particles size range was 0.2 - 0.6 mm; the crystal form of clarithromycin in the granule did not change; enteric-coated granules accumulated release in 0.1 mol L(-1) hydrochloric acid in 2 h was less than 10%, while in pH 6.8 phosphate buffer in 1 h was more than 80%. The taste masking and enteric-coated clarithromycin granules not only have good taste masking effect, but also have a good release behavior. It is expected to have better clinical application.
