In the last few years,the morbidity of pulmonary fungal infection is keeping increasing.However,misdiagnosis is very common in clinical practice since it has no specific clinical characteristics.Subsequently,delayed treatment happened.Laboratory test is the key method to diagnose pulmonary fungal infection.In fact,only pathology and positive cultural results obtained from germfree specimens could make the final diagnosis.Recently,some new methods put into effect such as G-test and GM-test.These methods greatly improve the early diagnosis of invasive fungal infection.Among them,PCR is a very prospective way.Nevertheless,the most basic and common used way is to detect and analysis sputum,blood and the specimen obtained through bronchoscopy.The specimen collecting process need to be standardized and the results need to be evaluated along with the clinical data.

Atypical pathogens are very common in community-acquired pneumonia(CAP) with the morbidity of about 22%(20%～28%).Therefore,CAP guidelines around the world usually emphasize the importance of atypical pathogens.The diagnosis tests are also listed in the guidelines,but only applied among inpatients.Japanese Respiratory Society recommended the diagnosis criteria of atypical pneumonia based on the clinical characteristics for the first time in the world.All guidelines recommended that empirical antibiotic therapy should cover those atypical pathogens when Mycoplasma pneumoniae,Chlamydia pneumonia or legionella pneumophilia infection are possibly exist.Antibiotic therapy against Mycoplasma pneumoniaen and Chlamydia pneumonia should be considered among outpatients and inpatients as well as anti-legionella pneumophilia therapy in severe patients in ICU.The recommended regimen is beta-lactam antibiotics combined with macrolides or fluoroquinolones alone.

The incidence of gram-positive coccus infection was keeping rising in recent years,with increase in hospital-and community-acquired pneumonia,as well as the incidence of infection caused by drug-resistant bacteria.Staphylococcus sp.,Streptococcus sp.and Enterococcus sp.were the most common pathogens inducing infection of the respiratory system,among which Streptococcus ranked the first.Streptococcus pneumoniae is still the most common pathogen causing respiratory infection.Recently,infection produced by penicillin-resistant strains of Streptococcus pneumoniae became more and more prevalent,leading to frequent failure in treatment.Regarding to Staphylococcus aureus,the methicillin-resistant strains (MRSA) account for approximately 60% of the pathogens inducing hospital-acquired infections,and what is worse,such a tendency is spreading to community,while the features of community-acquired MRSA infections (CA-MRSA) are very different from that of hospital-acquired MRSA infections (HA-MRSA).The purpose of present article is mainly to summarize the advances in diagnosis and treatment of pneumonia caused by Streptococcus pneumoniae and Staphylococcus aureus.

Objective To reveal the literature resources in traditional Chinese medicine from the end of the Qing Dynasty to 1949 .Methods The papers published in journals of traditional Chinese medicine from the end of the Qing Dynasty to 1949 were statistically analyzed .Results The largest number of journals was published in Shang-hai, the largest number of papers was published in Guanghua Medical Journal, 95%of the papers were published by a single author, the contents were focused on classical prescriptions and proved recipes, food therapy, disease treatment, baby care knowledge, and the most commonly studied were infectious diseases, such as exogenous febrile disease, cholera, and malaria.Conclusion The papers published in journals of traditional Chinese medicine from the end of the Qing Dynasty to 1949 are focused much more on the application of the knowledge about traditional Chinese medicine , but less on the theories of traditional Chinese medicine .

As a species of acute respiratory tract pathogen in mankind, Chlamydia pneumoniae can cause upper respiratory tract infection, pneumonia, it may also play an important role in bronchial asthma, chronic obstructive pulmonary diseases, sarcoid, lung cancer.

Chlamydia pneumoniae is one of the most common pathogens causing community acquired pneumonia.It may activate immune cells,release mediators of inflammation and cytokine and cause immune response.Researches on its signal transduction after infection through Toll-like receptors may help prevent and cure chlamydia penumoniae infection disease.

Pseudomonas aeruginosa,a ubiquitous organism,shows a remarkable resistance to antibiotics because of its low permeability of the outer-membrane,over-expression of efflux pumps,inactivation of antibotics,or mutations in targets.These mechanisms are often present simultaneously,and increase the burden on clinical therapy.

Objective To compare the effects of invert sugar versus 10% glucose on the blood glucose concentrations of patients in neurosurgical intensive care unit .Methods This is a prospective ,randomized ,double blind and compared study .A total of 40 in-sulin-requiring neurosurgical critical patients were randomized to receive intravenous ,1 000 mL ,either 10% invert sugar (experi-mental group) or 10% glucose(control group) on their first day when they were admitted to the intensive care unit (ICU ) .Blood glucose concentrations were measured every four hours and liver and kidney function indicators were recorded respectively .We’ve also compared the difference of the blood glucose concentrations changes between the two groups .Results There were significant differences in the glucose concentration between the two treatment groups (P<0 .05) ,whereas no significant differences in the inci-dences of hypoglycemia ,renal failure and hepatic damage were observed .No allergic reactions were found in both groups .Conclusion 10% invert sugar is a better choice for neurosurgical critical patients who need regular insulin infusion to control blood glucose .

It has been proved that severe acute respiratory syndrome (SARS) is caused by a novel coronavirus. Detecting disease in its early stage, understanding its pathways of transmission and implementing specific prevention measures for the disease are very important in the course of disease control. China has established the definitions of suspected and confirmed cases of SARS. But the laboratory tests and definitions for the diagnosis are limited.Now the primary measures for SARS include isolation, therapeutics application with ribavirin and corticosteroid, mechanical ventilation, etc. Convalescent plasma is being explored.There still are many problems to be solved in the course of conquering SARS.

The numbers of eosinophils and mast cells expressing 5-lipoxygenase of airway in aspirin-induced asthma (AIA) increased. LTC 4 synthase, the terminal enzyme for cys-LT production, is overexpressed markedly in bronchial biopsy specimens of most patients with AIA. These characterized the unique airway inflammation of AIA which may illuminat the pathogenesis of AIA to some extent.
