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 .

Autophagy is a highly conservative biological behavior in eukaryotic cells. This dynamic process involves "wrapping" cytoplasmic components and combining with lysosomes in cells for catabolism. The catabolic effect of autophagy can eliminate toxic substances in cells, maintain homeostasis in the intracellular environment, and produce small molecules, such as amino acids, which nourish cells, thereby allowing them to survive. Autophagy can inhibit the occurrence of tumors by maintaining homeostasis in the intracellular environment. However, it can promote the proliferation, invasion, and metastasis of malignant tumor cells. Autophagy can regulate the microenvironment of tumor cells and has an important role in a series of processes, such as anoikis, tumor dormancy, and epithelial-mesenchymal transition.

Seeding cells play an important role in the peripheral nerve damage repair. Seeding cells studied conse- quently in peripheral nerve are Schwann cells, bone marrow mesenchymal stem cells and neural stem cells. Schwann cells, the first seeding cells, are various unique glial cells in the peripheral nervous system, which can form the myelin sheath for insulation and package of the neuron projecting axons in the peripheral nervous system so that the conduction velocity of the nerve signal was accelerated. It can be proved that Schwann cells played an important role in the maintenance of peripheral nerve function and in the regeneration process after peripheral nerve injury. The second, bone marrow mesenchymal stem cells are the various mesenchymal stem cells mainly exist in the systemic connective tissues and organs. These functional stem cells are often studied at present, and it has been found that they have exuberant proliferation and differentiation potentials. Neural stem cells, mentioned the third in sequence, are the kind of pluripotent cells with multi-directional differentiation, which could conduct the self-renewal function, and generate and differentiate neurons, astrocytes and oligodendrocytes through asymmetric cell division. These three types of seed cells are discussed in this paper.

With the methods of light microscopic histochemistry and electron-microscopic cytochemistry, we studied the changes of lactate dehydrogenase (LDH) and succinic dehydrogenase (SDH) in the anoxic myocardium of the mice; to which normal saline (INSAM group) or 10％ aqueous extract of Ginsengradix rubra (IGRAM group) was injected before the anoxic experiment. The results were as follows:Ⅰ. The Light Microscopic Study:1. In the myocardial sections of the INSAM group, the reaction of SDH of myofibrillae are variegated and the fibrillae vary in thickness. Granular mitochondria are clearly stained and arranged in alignment in the intermyofibrillar spaces. The intercalated discs fail to be stained and their spaces widen. In the IGRAM group, the reactions of SDH are similar to that of the normal control. The enzyme reaction product in the myofibrillae appear as homogeneous diffuse blue precipitate of formazan, the cross striations of myofibrillae are clear and strings of mitochondria are visible.2. The reactions of LDH in the INSAM group reveals that myofibrillar staining is also lost in a length of myofibrilla, strings of mitochondria are clearly stained. The reaction in the IGRAM group is similar to that of the normal control. In the myofibrillae there is a homogenous continuous violet precipitate of formazan.Ⅱ. The Electron-Microscopic Study:1. The reaction of SDH in the INSAM group shows that the enzyme activity in the mitochondrial inner membrane and the cristae is stronger than that of the normal control. The increased activity is represented by the increase of electronic density or darkening and thickening of the membranes. However, the activity in the IGRAM group is simillar to that of the normal control but weaker in reaction.2. The reaction of LDH in the INSAM group reveals that the enzyme activity exhibited by membrane darkening is obviously stronger than that of the normal control but in the IGRAM group it shows clearly a weaker reaction.The results mentioned above suggest that Ginsengradix rubra might alleviate the metabolic disturbance caused by myocardial anoxia.

Both ?-cell dysfunction and insulin resistance contribute to the development of type 2 diabetes, and ?-cell function, especially early insulin secretion, is important in maintaining normal glucose tolerance. This review focuses on the ciritical role of ?-cell dysfunction in the pathogenesis of type 2 diabetes.

The academic levels and contents of papers published in China on random control tests of treatment of infantile mycoplasmal pneumonia with traditional Chinese medicine were assessed and analyzed according to the current treatment of infantile mycoplasmal pneumonia with traditional Chinese medicine and the problems existed in order to further improve its clinical treatment.
