Objective To investigate the effect of HGF on proliferation and migration in cultured human RPE cells. Methods Human RPE cells cultured in serum-free medium were treated with HGF(1,2,10,50,100 ?g/L), and MTT assay was used to detect the growth of the cells; an in vitro wound healing model was used to count the number of cells that had entered the denudate area in RPE migration treated with HGF (1,2,10,50,100 ?g/L) after 20 h. Results HGF(10,50,100 ?g/L) increased proliferation rates of cultured human RPE (18 2 % to 34 8 %), and at a concentration of 50 ?g/L on day 3 HGF induced the maximal increase of proliferation( P

Objective To analyze the performance of the glioma in proton magnetic resonance spectroscopy (1H-MRS) and diffu-sion tensor imaging(DTI) ,and to explore the relationship between the characteristics and pathological grade .Methods The 41 ca-ses of glioma patients were divided into two groups according to the World Health Organization (WHO) classification method :the low-level group and the high-level group .The patients underwent conventional magnetic resonance imaging ,DTI and 1H-MRS ex-amination ,and the ipsilateral placeholder district and contralateral reference zones ADC ,FA ,Cho ,NAA and Cr values were meas-ured .Results The difference of ADC and FA values in solid area between the two groups was significant compared with the contra-lateral ones (P< 0 .05) .The difference of ADC and FA value of the gliomas between the two groups was also significant (P<0 .05) .The NAA/Cr and Cho/Cr values in the two groups of glioma tumor was significantly different compared with the contralat-eral ones (P<0 .05) .The NAA/Cr and NAA/Cho values of the gliomas between the two groups were also significantly different (P<0 .05) .Conclusion The performance of glioma in 1H-MRS and DTI between the two groups showed significantly different .

Objective To assess whether it have difference between mannitol combined with glycerin fructose and only use mannitol for the treatment of cerebral hemorrhage ,which provides relevant evidence‐based basis for guiding clinical treatment of cerebral hemorrhage .Methods We used literature retrieval through to the China national knowledge internet (CNKI) ,China biolo‐gy medicine disc ,VIP Chinese periodical database ,Wanfang data knowledge service platform and manual retrieval ,and formulate the inclusion and exclusion to screening literature ;and using the Jadad quality evaluation method to evaluate literature which had been included ,heterogeneity inspection at the same time .If the effect of multiple resulted ,we used fixed effect model ;on the other hand , used a random effects model .Results Mannitol combined glycerol fructose significantly improved symptoms and nervous function in patients with cerebral hemorrhage ,and the difference was statistically significant (RR=1 .12 ,95% CI:1 .03 -1 .22 ,P<0 .01);mannitol combined glycerol fructose significantly decreasd impaired renal function and complications (RR=0 .34 ,95% CI:0 .25-0 . 47 ,P<0 .01);mannitol combined glycerol fructose significantly decreasd severe unbalance of electrolyte after taking the medicine (RR=0 .31 ,95% CI:0 .19-0 .49 ,P<0 .01) .Conclusion Compared to use mannitol only ,combination with mannitol and glycerin fructose could effectively improve the prognosis of patients with cerebral hemorrhage ,and reduce the side effects .

Objective To develop social integration scale of the disabled,and to test the reliability and validity of the scale.Methods 511 disabled persons were investigated by self-made social integration scale and Chinese version of positive and negative affect schedule (PANAS-C).Results The Scale was composed of three factors:self integration,relationship integration and affection integration,and they explained 47.39％ of variance.The theoretical model fit could be accepted (x2/df =2.051,P＜0.001;RMSEA =0.046;GFI =0.884;CFI =0.926;IFI =0.927).The factors had significant correlated with positive affect (r=0.34-0.55,P＜0.01)and positive affect (r=-0.12--0.32,P＜0.01).The high score group and low score group of social integration had significant differences in positive affect (t=13.77,P＜0.01)and negative affect(t=-7.58,P＜0.01).The cronbach's alpha coefficients of the scale and the three factors were 0.94,0.92,0.87 and 0.89 respectively,and the seven sub-factors'cronbach 's alpha coefficients were from 0.76 to 0.87.Conclusion The theory construct of social integration of the disabled is multi-hierarchical and multi-dimensional.The scale has acceptable reliability and validity,and can be used to assess the degree of social integration of the disabled.

Objective To explore the characteristics of resilience and the relationships between resilience and social integration of disabled people.Methods By convenient sampling,a total of 702 disabled people were investigated by Connor-Davidson Resilience Scale,Social Integration Scale of the Disabled and self-made general questionnaire.Results The score of resilience of disabled people(53.27± 18.21) was lower than chinese community people(65.4± 13.9,t=-13.19,P＜0.01).The resilience scores were significantly lower of the disabled people who came from rural areas,younger(≤ 24 years old) or older(≥ 60 years old),and were disabled from birth had poor family economic conditions,and had no insurances(P＜0.05,P＜0.01).But the disabled people who had university degree or above,married,working,and had warm and harmonious family atmosphere,had significantly higher resilience scores (P＜0.05,P＜0.01).The vesilience and three sub-factors were significantly correlated with social integration (r=0.38-0.66,P＜0.01).The high resilience group had higher score in integration and three dimensions compared with the low resilience group(t=11.60-19.02,P＜0.01).Tenacity and strength directly influenced the three dimensions of social integration (the path coefficient were 0.18-0.46,P＜0.01).Conclusion The resilience of the disabled people is lower,and there are close relationships between resilience and social integration.The training of tenacity and strength is beneficial to social integration of the disabled people.

Objective: To design the proficiency testing (PT) project (No. NIFDC-PT-183) for assays of bismuth potassium citrate capsules and organize to assess the proficiency of complexometric titration in laboratories, and provide some technical analyses and advices.
Methods: Two groups of samples with different concentration were prepared. The uniformity was evaluated with one-way analysis of variance and the stability was confirmed with t-test, whose results all conformed the requirements. The samples with three combinations were randomly distributed to 279 laboratories. The determination was performed according to the assays of bismuth potassium citrate capsules in Volume Ⅱ of the Chinese Pharmacopoeia 2015. The median value and normalized interquartile range (NIQR) of robust statistical analysis was adopted and Z-scores were used to evaluate the results from each of laboratories.
Results: Among 279 laboratories, 240 laboratories results were satisfactory, 23 were questionable, and the other 16 were unsatisfied. The satisfaction rate was 86.0%.
Conclusion: The overall capacity of national laboratories for assays of bismuth potassium citrate capsules is good while a portion of participants require further improvement.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.
