The rural health service is the important part of China’s health initiative and improving the rural grass-root health technical capabilities and service level marks the strategic initiatives and present needs to promote the rural health service development. The Traditional Chinese Medicine ( TCM) has a broad and solid mass base in rural areas and concentrating on the promotion of the TCM’s appropriate technologies constitutes an important way to strive for the rural health services development. Gangu and Jingning Counties of the Gansu province fully use the Health XI Project platform to promote the TCM’s appropriate technology application and explore the service model. With the achieved good experiment results, effective development of the TCM services is promoted.

Lymph node metastasis is the main mode of metastasis of thyroid papillary carcinoma.In the central compartment lymph node dissection,the lymph node posterior to right recurrent laryngeal nerve is hidden because of its deep anatomical position,which is easy to be missed during the operation and becomes one of the factors that affect the recurrence of thyroid papillary carcinoma.The metastasis rate of lymph node posterior to right recurrent laryngeal nerve is 10%-30%,which is related to the tumor size,location and other factors,and its position in the surgical treatment of thyroid cancer is increasingly prominent.

Mycobacterium abscessus complex (MABC), a rapidly growing nontuberculous mycobacterium, has received increasing attention worldwide due to its rising isolation rate. The similarity of symptoms between MABC pulmonary disease and tuberculosis, different treatment methods required by different subtypes, as well as high levels of innate, adaptive and acquired antibiotic resistance, make MABC treatment more difficult and lead to unfavorable clinical outcomes of patients. This article reviews the basic characteristics, common antibiotic resistance mechanisms, as well as diagnosis and treatment of MABC, to provide reference for future research and clinical treatment of MABC lung disease.

Objective:
To prepare strains of influenza A (H7N9) pseudovirus derived from different districts of China for vaccine efficacy evaluation.
Methods:
Phylogenetic tree was built based on hemagglutinin (HA) amino acid sequence analyses from 29 influenza A (H7N9) virus strains and 6 influenza A (H7N9) virus strains with HA determinants variation were selected. 293FT cells were co-transfected with plasmid pNL4-3-Luc.R-E-, pVRC-HA and pVRC-NA with codon-optimized hemagglutinin (HA) and neuraminidase (NA) derived from the six influenza A (H7N9) virus strains, respectively. Transmission electron microscopy assay and Western blot analysis were performed to demonstrate morphology and specificity of these particles, luciferase activity assay and hemagglutinin titers detection were used to determine their infectivity and hemagglutinin activity. And finally, pseudovirus-based neutralization assays were evaluated with HA immunized mice serum.
Results:
Six influenza A (H7N9) peseudovirus particles derived from different districts of China were selected and prepared. All of the particles bearing HA and NA were characterized with classic influenza virus morphology, with TCID50 titer ranged from 104TCID50/50 μl to 105TCID50/50 μl and with hemagglutinin activity ranged from 64 to 512. Neutralization efficacies on influenza A/Shanghai/1/2013(H7N9) HA vaccine serum against 100TCID50 dose of these pseudovirus particles indicated their potential application in the vaccine cross-protective evaluation in future.
Conclusions
Six influenza A (H7N9) pseudovirus derived from different districts of China with potential antigenic variation on HA were constructed successfully, established foundation for their further application in vaccine cross-reactive efficacy evaluation.
