Objective To investigate the effect of astragalus polysaccharides (APS) on the differentiation of rat bone marrow mesenchymal stem cells (BMSCs) to neurones, adipocytes, osteoblasts and chondrocytes, and provide basis for the development of effective and low toxic differentiation inducing agents. Methods BMSCs were isolated from SPF Wistar rats, purified, expanded and cultured to family 3. The appropriate concentration of APS was filtered out by MTT assay. The F3 cells were randomly divided into control group and induced group (neural induction, adipogenic induction, osteogenic induction, cartilage induction). The effects of APS and classical chemical drugs on differentiation were measured by toluidine blue, oil red o and alizarin red staining. The protein expression of NSE, LPL, collagen Ⅰ and collagen Ⅱ were examined by Western Blot. Results MTT assay showed that 1 g/L APS promoted the proliferation better than other concentrations especially in 48 hours. The morphologic change of the cell from BMSCs was uniformly positive to toluidine blue staining, and was negative to oil red o and alizarin red staining. Western blot showed that the protein expression of the cell from BMSCs was positive for NSE but negative for LPL, collagen Ⅰ and collagen Ⅱ. Conclusion BMSCs induced by APS can differentiate to neurone and fail to differentiate to adipocytes, osteoblasts and chondrocytes in vitro.

Objective To evaluate the reporting and methodological quality of randomized controlled trials (RCTs) related traditional Chinese medical nursing which published in key Chinese journals.Methods Electronic databases were searched for collecting RCTs related traditional Chinese medical nursing which published in key Chinese journals.The impact factors of all these journals ranked the first three in the Chinese S & T journal citation reports,2013.The CONSORT statement and Cochrane collaboration risk of bias tool were applied to evaluate the reporting and methodological quality respectively.Results A total of 135 articles were identified to meet the criteria.To the best of our knowledge,however,none of these articles have reported the 14 items in the CONSORT statement,either without the CONSORT flow diagram.According to the Cochrane Collaboration Risk of Bias Tool,17.0％(23/135) of these articles was confirmed to be high risk of bias,with the rest uncertain in the degree of bias.Conclusions The reporting and methodological quality of RCTs on traditional Chinese medical nursing were poor.It is urgent to improve the methodological and reporting quality of RCTs on traditional Chinese medical nursing researches.

Objective To compare the methodological and reporting quality of case-control studies published in higher impacted nursing periodicals,other nursing journals and compositive medical journals.Methods All nursing specialization and integrative journals in China mainland were searched from the inception till December 2013.The methodological and reporting quality was assessed according to NewcastleOttawa Quality Assessment Scale (NOS) and strengthening the reporting of Observational Studies in Epidemiology Statement (STROBE) respectively.Results The systematic literature search yielded 3 579 publications potentially relevant studies.Then,a total of 94 hteratures met the inclusion criteria were identified.The average score of methodological quality and reporting quality were(4.86±1.33) and (16.11±2.41) respectively.Additionally,there was no significant difference in methodological quality and reporting quality among higher impacted nursing periodical,other nursing journals and compositive medical joumal.Condusions The number of case-control studies in Chinese nursing field revealed an increasing tendency,and these literatures addressed a wide range of research fields.However,most quality of the case-control studies published in China were rela-tively poor,and both methodological and reporting quality should be further improved.

Objective To evaluate the association between the concentration of particulate matter (PM2.5)and asthma attack in children.Methods The computer and databases were used to search the key wordsAsthma andChild were searched by means of the subject headings ( Asthma andChild) and free words (Asthma * , Child *andPediatric * etc.),moreover PM2.5 was searched on the basis of free words such asPM2.5, Particulate Matter *which were linked withAND in PubMed and Medline database.Furthermore,the key words asthma AND (Child OR Pediatric OR Infant) AND (PM2.5 OR Particulate Matter OR Inhalable Particles) for keywords were searched in CBM,CNKI,VIP and Wanfang databases.The literatures included those from the initial computer database up to those of December 2014 from computer database.Meanwhile manual research was added to screen literatures according to the standards of inclusion and exclusion.Newcastle-Ottawa Scale was employed to assess the quality of the included literatures including selection,comparability and outcomc.Data wcre synthesized and analyzed by Rcvman5.3 and Stata12.0 version for statistical analysis,heterogeneity test,sensitivity analysis,subgroup analysis,and so on.Results A total of 17 literatures involving 1326573 children were included.The findings from quality assessment involved 2 studies for 8 scores,2 for 7 scores,7 for 6 scores,5 for 5 scores,and 1 for 4 scores,respectively.The result of Meta-analysis showed that the combined the odds ratio (OR) of PM2.5 with childhood asthma attack was 1.06,and 95％ confidence interval(CI) was 1.03-1.08.Subgroup analysis showed that the OR on the asthma hospital visit equaled to 1.03 (95％ CI 1.01-1.06),and the OR on the asthma symptom equaled to 1.11 (95％ CI 1.06-1.16),moreover,subgroup analysis between developed and developing countries showed that the OR of the asthma on developing countries corresponded to 1.04 (95％ CI 1.02-1.06),and the OR of the asthma on developed countries corresponded to 1.06 (95％ CI 1.03-1.09).Conclusion There is a positive correlation between concentration of PM2.5 and asthma attack in children.

Objective To study the surface electromyographic signal characteristics of submental and infrahyoid muscles when swallowing in patients with nasopharyngeal carcinoma (NPC) following radiotherapy.Methods Fifteen post-radiotherapy NPC patients with pharyngeal dysphagia confirmed by videofluoroscopie swallowing study (VFSS) were selected into the patient group,while another 15 healthy subjects were recruited into the healthy group.Surface electomyography (sEMG) was used to collect sEMG signals from submental muscles and infrahyoid muscles during both dry and 3 ml thick liquid swallowing,and sEMG duration,average amplitude and peak amplitude parameters were compared between the two groups.Results Compared with healthy subjects,the patient group showed significantly longer sEMG duration of submental muscles and infrahyoid muscles during dry swallowing and 3 ml thick liquid swallowing (P＜0.05).Moreover,significantly longer sEMG duration of submental muscles and infrahyoid muscles was observed when swallowing 3 ml thick liquid,compared with dry swallowing (P＜0.05).The average sEMG amplitude and peak amplitude of submental muscles and infrahyoid muscles of patients when dry swallowing and 3 ml thick liquid swallowing were both significantly higher than those of healthy subjects (P＜0.05).Conclusion Submental muscles and infrahyoid muscles manifested enhanced contractions during swallowing in NPC patients with dysphagia,which played a compensatory role after radiotherapy.

Objective To explore the preventive effect of percutaneous endoscopic gastrostomy (PEG) on aspiration pneumonia in patients with dysphagia.Methods The clinical data of 43 patients undertaking PEG was retrospectively collected and the incidence of aspiration pneumonia,microbiological examination of sputum and antibiotics use before and after PEG in all the patients were compared.Results After PEG,the incidence of aspiration pneumonia decreased significantly from 90.7％ to 53.5％ according to clinical diagnosis,from 70.4％ to 18.5％ according to the chest imaging.The use of β-lactamase inhibitor compound decreased significantly,but the detection rate of pseudomonas aeruginosa increased significantly compared with that before PEG.Conclusion PEG can decrease the incidence of aspiration and antibiotics use,and may increase the chances of pseudomonas aeruginosa colonization in the lower respiratory tract.

Objective To analyze the effect of ultrasound-guided glucocorticoid injection on different pathologies of the shoulder retrospectively.Methods Clinical data were collected describing 75 patients with shoulder pain who received ultrasound-guided glucocorticoid injection and finished 3 month follow-ups in the rehabilitation clinic of the Third Affiliated Hospital of Sun Yat-sen University between April and September of 2017.The patients were divided into three groups based on their different injection sites:group 1 was injected at the subacromial bursa alone,group 2 was injected at both the subacromial bursa and the coracoid bursa,while group 3 was injected at the subacromial bursa and the long head of the tendon sheath of the biceps brachii.A shoulder pain and disability index (SPADI) was used to quantify the pain and disability of each patient before and after the injection.Results Significant improvement was observed in the average pain and disability scores of all groups at 1 week,1 month and 3 months after the injection.Moreover,significant and continuous improvement was observed in the average pain and disability scores of groups 1 and 3,as well as the average disability score of group 2 from right after the injection until the last follow-up.However,no significant differences were found in the average pain score between one and three months after the injection.There was no significant difference among the 3 groups in the average pain and disability scores before and immediately after the injection.Conclusion Ultrasound-guided glucocorticoid injection is effective and persistent for treating shoulder pain with different pathologies.

This paper summarized Professor ZHOU Zhongying's experience in differentiating and treating hepatitis and liver cirrhosis from deficiency and excess. It is considered that the pathogenesis of hepatitis and liver cirrhosis belongs to deficiency in root and excess in branch， with depletion of liver， spleen and kidney as the root， and constraint and bind of damp-heat and stasis toxin as the branch. Moreover， mutual cause and promotion between deficiency and excess leads to the disease. For general principle of treatment， it is recommended to clear and transform pathogenic excess， supplement deficiency and rectify the healthy qi. In the early stage of hepatitis and cirrhosis， excess pathogen hyperactivity is the main manifestation， which can be treated by clearing and transforming damp-heat and stasis toxin， supplemented by regulating spleen and stomach， with modified Yinchenhao Decoction （茵陈蒿汤） and Biejiajian Pill （鳖甲煎丸）. In the middle and late stages， cases with deficiency-excess complex were more common， which should be treated by clearing damp-heat and stasis toxin， regulating and supplementing liver-spleen-kidney， using medicinals with the function of clearing heat and dispelling damp， dissolving stasis and resolving toxins to treat the branch. Moreover， Liujunzi Decoction （六君子汤）， Yiguan Decoction （一贯煎）plus Erzhi Pill （二至丸） and Buzhong Yiqi Decoction （补中益气汤） modifications are suggested respectively in correspondence to the different kinds of root deficiency including irregular liver and spleen， liver and kidney yin deficiency， and liver-spleen-kidney deficiency.
