OBJECTIVE To investigate clinical status,distribution of the genera,and risk factors of pneumonia caused by fungi in hospitalized senile patients.METHODS The notices of hospitalized senile patients from Jan 2000 to Apr 2003 were analyzed according to Diagnosis Standard of Nosocomial Infection published by National Ministry of Health.RESULTS Totally 135 cases were collected.The isolating ratio of Candida albicans ranked first(54.8%),followed by C.tropicalis(20.0%).The risk factors included underlying diseases,invasive surgical procedure,and prolonged hormones and antibiotics therapy.CONCLUSIONS To prevent and control pneumonia caused by fungi in hospitalized senile patients,the measures such as curing the underlying diseases,reducing invasive surgical procedures,and using antibiotics reasonably should be adopted.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on hippocampus metabolic changes in rats with temporal lobe epilepsy. Methods A chronic temporal lobe epilepsy model was established by use of lithium-pilocarpine in rats. The hippocampus metabolism of the rats were detected by 1H-MRS method before and after the rTMS and compared with that of the normal controls. Relative ratios of N-acetylaspartate (NAA), choline (Cho), glutamate (Glu) and ?-aminobutyric acid (GABA) over creatine (Cr) were calculated. Results Compared with normal control rats, NAA/Cr and GABA/Cr ratios decreased significantly and Cho/Cr ratios increased significantly in hippocampus of the rats with temporal lobe epilepsy. After rTMS NAA/Cr and GABA/Cr ratios increased significantly and Cho/Cr ratios decreased significantly in hippocampus of rats with temporal lobe epilepsy. However, rTMS did not significantly affect the Glu/Cr ratio in hippocampus of the rats with temporal lobe epilepsy. Conclusion rTMS could improve the hippocampus metabolism and exert a neuroprotective effect against brain damage induced by epilepsy.

let-7e is one member of let-7 miRNA family, a class of endogenous noncoding RNA which consists of 22 nucleotides. The recent miRNA profiles investigation and analysis results showed that let-7e could be involved in embryonic stem cells differentiation, tumorigenesis in cancer, temporal lobe epilepsy and sleep loss, lipopolysaccharide induced inflammation by regulating its target mRNA expression. This paper gives a review of the important biological function of let-7e.

Objective To detect expression of PRKACB protein in non-small cell lung cancer ,thus to study its clinical significance and to analyze the relationship between PRKACB expression and prognosis .Methods We detected the PRKACB protein using immunohistochemistry in 109 lung cancer tissues and corresponding adjacent 20 normal tissues of non-small cell lung cancer patients .Results Compared with normal tissues , the level of PRKACB significantly decreased in lung cancers (χ2 =25.217,P<0.05),and was associated with differentiation (χ2 =9.664,P<0.05),lymph node metastasis(χ2 =4.430,P<0.05),and TNM staging(χ2 =4.430,P<0.05). Furthermore,the low expression of PRKACB protein was correlated with poor prognosis ( overall survival and disease-free survival ) of the patients .Conclusion PRKACB was lowly expressed in non-small cell lung cancer ,and associat-ed with clinical features ,which indicated its important role in clinical diagnosis of non-small cell lung cancer .

By interpreting the connotation of physical factors and its significance in the syndrome differentiation of traditional Chinese medicine (TCM), ideas and methods of the combination of physique differentiation and syndrome differentiation of coronary heart disease (CHD) were proposed. The physique classification research was promoted and standardized. Research methods of physique differentiation were improved. The connotation of relationship between constitution and syndrome was mined. The essence of different syndromes was explored on different syn-dromes of CHD. The physique differentiation, disease differentiation and syndrome differentiation were integrated with the viscera-state theory and syndrome factor differentiation theory. The difference of proteomics technology was used as the means to reveal the pathogenesis of same disease with different syndrome of different CHD constitution. Multidisciplinary crossover study was developed on CHD with constitution theory of TCM and clinical actively, so as to make it better to direct the clinical scientific research practice of CHD.
