The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

From the perspective of compound type,the bioactive metobolites from Gliocladium are reviewed,and the research advancement in future are proposed.

BACKGROUND:Placental mesenchymal stem cel s with rich sources are similar to bone marrow mesenchymal stem cel s in terms of morphology, surface markers and differentiation potential, which are one of ideal mesenchymal stem cel s in human body. However, there are few studies addressing the ultrastructure and phagocytotic function of human placental mesenchymal stem cel s and its physiological role in the the placenta has been little explored. OBJECTIVE:To investigate the ultrastrcture and phagocytotic function of placental mesenchymal stem cel s. METHODS:Placental mesenchymal stem cel s obtained from five placentae of normal pregnancy were cultured in vitro and observed for ultrastructure under transmission electron microscope. The fluorescent beads were added in the supernatant for 3 hours, and then the phagocytosis of placental mesenchymal stem cel s was evaluated by flow cytometry. RESULTS AND CONCLUSION:Under the transmission electron microscope, placental mesenchymal stem cel s had large nuclei with prominent nucleoli. In the cytoplasm, a plenty of rough endoplasmic reticula was seen, dilated or stacked. The cytoplasm was also rich in Golgi apparatus and lysosomes. The cel surfaces were covered by microvil i. The intercel ular junctions could be seen occasional y. A part of cel s from these five samples could phagocytose fluorescence beads, which ranged from 49.6%to 18.4%. The ultrastructural characteristics of placental mesenchymal stem cel s suggested these cel s were active to synthesize and secrete proteins and had phagocytotic function, indicating placental mesenchymal stem cel s may play a role in keeping the balance of micro-environments and clean the foreign substances in the placenta.

To determine the etiologic agent of an outbreak of influenza viruses from Changsha Foothill Mountain International School in 2009, and to analyze the HA Gene Characteristic of the H1N1 influenza viruses. Twenty-five nasopharyngeal swab specimens from the outbreak of influenza viruses were tested by conventional RT-PCR and influenza viruses isolated simultaneously. Virus isolated (A/Yuelu/314/2009) from the outbreak was sequenced by CEQTM 8000 Genetic Analysis System and the sequencing results submitted to GenBank (Accession No: FJ912843), then the sequencing data was analyzed by ClustalX and Mega4.1softwares. Results showed the influenza viruses A(H1N1) of positive were 18 cases by influenza viruses isolated tests and 21 cases by conventional RT-PCR, respectively. The nucleotide and amino acid sequence homology of the HA gene of A/Yuelu/314/2009 are 99% compare with the vaccine strain (A/Brisbane/59/2007) in 2008~2009 years. The HA sequence data also showed that had 6 amino acid mutations (V148A, S158N, G202A, I203D, A206T, W435R), and the S158N located at antigenic site B of HA protein. Nine potential glycosylation sites (27, 28, 40, 71, 151, 176, 303, 497, 536) in the HA sequence of A/Yuelu/314/2009 is the same with A/Brisbane/59/2007, and the sequences of potential glycosylation sites were conserved. In this study, laboratory evidence diagnosed seasonal influenza A virus (H1N1) as the etiologic agent of the outbreak. The virus isolated (A/Yuelu/314/2009) strain of H1N1 subtype is not a new variant in Changsha in 2009 compare with the vaccine strain (A/Brisbane/59/2007), the outbreak of influenza A virus (H1N1) from Changsha Foothill Mountain International School maybe are caused by the change in genetic characteristics between vaccine strains and the decreased of immunity to influenza A virus (H1N1) in the crowd.

Diabetic macular edema(DME)and age-related macular degeneration(ARMD)are the leading causes of visual impairment and blindness worldwide, and their common pathological features are increased vascular permeability and abnormal neovascularization, in which cytokines such as vascular endothelial growth factor(VEGF)and angiopoietin-2(Ang-2)play an important role. Intravitreal injection of anti-VEGF agents significantly changed the clinical management of DME and ARMD, but limitations such as the non-responsive cases, the treatment burden and risks caused by frequent injections need to be overcome. Faricimab, a novel bispecific monoclonal antibody that simultaneously targets VEGF-A and Ang-2, can effectively reduce vascular permeability, decrease the number of neovascularization and alleviate retinal edema. Registered clinical studies have shown that Faricimab is effective in improving vision and reducing retinal edema, which is non-inferior to Aflibercept and Ranibizumab, maintains a long dosing interval, and has a high safety profile. This article reviews the latest advances in the treatment of DME and ARMD with Faricimab.

Objective To explore the diagnostic significance of differential cell count in induced sputum to chronic cough and assessment of airway inflammation.Methods The sputum of 335 chronic cough patients were induced.Differential cell counts were measured in these samples.The side effects were observed during the induced procedure.The final diagnosis was made based on clinical manifestation and examination findings including pulmonary function tests,provocation test,induced sputum cell differentials, etc.Results The cause of chronic cough was defined in 322 patients.The six most important causes of cough were typical asthma(TA,n=84),eosinophilic bronchitis (EB,n=62),atopic cough (AC,n= 42),cough variant asthma (CVA,n=40),gastroesophageal reflux cough(GERC,n=37),rhinitis and/ or paranasal sinusitis (PNDs,n=32),and others and indefinite cause (n=25,13).Percentage of eosinophils were significantly increased in the induced sputum of AC,EB,CVA,and GERC patients (0.005,0.052,0.059,0.234) compared with those in other causes and the healthy controls (0) (P
