The treatment of traditional Chinese medicine (TCM) has been proved effective in clinical practice for thousands of years. To standardize the clinical protocols of TCM is absolutely necessary for enhancing the research quality of TCM and expanding the international influence of TCM. The standardization research on clinical protocols of TCM should be based on the basic theory of TCM and in the light of good clinical practice (GCP) principles. The clinical criteria for both diagnosis and efficacy evaluation of disease are also needed. To include all symptoms, tongue manifestations and pulse presentations into case report form, and to compare the differences in these clinical parameters between effective and non-effective cases by multivariate analysis may be helpful to find more specific indications for therapeutic protocol of TCM. Furthermore, It is suggested that two or more clinical trials on one therapeutic protocol are needed to identify its accurate indications.

Objective To explore the measures to prevent recurrent laryngeal nerve (RLN)injury during thyroid surgery.Methods The clinical data of 223 patients undergone thyroid surgery were retrospectively analyzed.Among the 223 surgeries,69 sides were undergone regional protection act of RLN and 191 sides were performed RLN exposure.Results There were 2 cases of RLN injury from the regional protection operation of RLN,including 1 case of temporary nerve injury which could be resulted from surgery clamp and 1 case of permanent nerve injury which might be caused by mistaking ligation during surgery.There was only 1 case of temporary nerve injury in RLN exposure procedure which was probably caused by the postoperative nerve edema and was recovered 2 months after the operation.The total RLN injury rate was 1.35％.Conclusion For benign thyroid lesions and non-dorsal lesions or during partial excision of the gland,the regional protection of RLN is helpful to prevent RLN injury.In cases with dorsal lesions of thyroid or contralateral RLN injury,or during lobe subtotal resection,lobe resection and reoperation,exposing RLN to prevent injury is necessary.Taking different approaches based on the profiles of lesions and surgical procedures to prevent RLN injury can significantly reduce the risk of RLN injury.

Objective To evaluate the imaging features of pneumonia caused by A (H1N1) influenza virus. Methods Imaging data of 51 patients with pneumonia caused by A H1N1 influenza were retrospectively reviewed. All patients underwent mobile chest radiographs and 44 patients underwent CT as well. On the basis of the lesion degree in the lung, the patients were classified into mild, moderate and serious types. Results Mild type showed patchy consolidation at chest imaging in 4 patients. Moderate type demonstrated consolidation and(or) ground -glass opacities more than 2 lung fields in 33 patients, including 30 bilateral and 3 unilateral. Serious type displayed diffuse consolidation and ground-glass opacities, probably accompanying with interstitial lesions in the lungs in 14 patients, including 6 patients with ARDS, 2 with infection and 1 with cutaneous emphysema. Conclusion The imaging features of pneumonia caused by A H1N1 influenza mainly manifest as consolidation and ground-glass opacities, probably accompanying with interstitial changes. The imaging findings show various in patients with infection. Some serious patients even develope to ARDS.

The practical experiences with subject service in Medical Library of Chinese PLA were summarized in terms of the establishment of user information records, accumulation and summation of information, and construc-tion of information platform. Suggestions were put forward for the improvement of subject service in Medical Library of Chinese PLA, such as holding the big information concept in the big data era, using the biomedical data as the target of study, providing various kinds of service, integrating seamless, dynamic and interactive library service into user service. The fact that focus on artificial intelligence, computer, information and coomunication technologies is one of the future directions was pointed out.

ObjectiveTo evaluate the biological characteristics of rat bone marrow mesenchymal stem cells (BMSCs) transfected with hypoxia-inducible factor-1α(HIF-1 α) gene.MethodsThe rat BMSCs of 3rd generation and the vector expressing HIF-1α gene (pcDNA3.1-HIF-1α) were provided by department of anesthesia,Tangdu Hospital,the 4th Military Medical University.BMSCs expressing HIF-1α gene (BMSCs-HIF-1α cells) were constructed by transfection of vector pcDNA3.1-HIF-1α into BMSCs by means of electroporation.Successful transfection of HIF-1α gene was confirmed by immuno-cytochemistry.Simple BMSCs and BMSCs-pcDNA3.1 cells were used as control cells.After being cultured in hypoxic condition HIF-1α expression was detected by Western blot analysis.Flow cytometry was used to determine the proportion of cells in G1,G2 and S phase and detect apoptosis.The proliferation index (PI) was calculated.The cell growth curve was described by MTT assay and the number of the 3 types of cells was recorded.ResultsA large number of deep blue granules were observed in the nuclei of BMSCs-HIF-1α cells using immuno-cytochemistry but no such granule was found in the two types of control cells.HIF-1α expression was significantly up-regulated and apoptosis rate (the number of apoptotic cella/the total number of cells examined) decreased in BMSC-HIF-1α cells compared with the control cells.The proportion of cells in S and G2 phase was significantly higher and the proportion of cells in G1 phase was significantly lower and PI higher in BMSCs-HIF-1α cells than in the control cells.The number of BMSCs-HIF-lα cells was significantly higher than the number of the two types of control cells at day 3-8 of culture.There was no significant difference in the above variables between BMSCs and BMSCs-pcDNA3.1 cells.ConclusionBMSCs-HIF-1α is successfully constructed by transfection of vector pcDNA3.1-HIF-1α gene into BMSCs by means of electroporation.
