Objective: To revise the Griffith Mental Development Scales and establish the norm being suited to the Chinese local conditions. Methods: The standardized sample consisted of 2022 children aged 0 to 7 years old was collected in a stratified and random way according to city rank, age, sex, paternal occupations. Each subject was tested individually and filled in a form. Results: The total sample had better representation. The mean of GQ was about 100, and the distribution of GQ is normal. Item analysis indicated that the item difficulty was about 0.5 and discrimination was from 0.62 to 0.78. A few orders of items were revised. The scorer reliability was 0.953. The test-retest reliability was 0.948. The correlation coefficients were 0.481 to 0.854 among the sub-scales or between sub-scales and General DQ. The result of exploratory factor analysis had three factors. The ratio of variance was 79.8%.Conclusion:Griffith Mental Development Scales have ideal reliability and validity.

Intravenous and intratracheal implantation of mesenchymal stem cells (MSCs) may offer ameliorating effects on pulmonary hypertension (PH) induced by monocrotaline (MCT) in rats. The aim of this study was to examine the anti-remodeling effect of intravenous MSCs (VMSCs) and intratracheal MSCs (TMSCs) in rats with PH, and the underlying mechanisms. MSCs were isolated from rat bone marrow and cultured. PH was induced in rats by intraperitoneal injection of MCT. One week after MCT administration, the rats were divided into 3 groups in terms of different treatments: VMSCs group (intravenous injection of MSCs), TMSCs group (intratracheal injection of MSCs), PH group (no treatment given). Those receiving saline instead of MCT served as negative control (control group). Pulmonary arterial structure was pathologically observed, pulmonary arterial dynamics measured, and remodeling-associated cytokines Smad2 and Smad3 detected in the lungs, three weeks after MCT injection. The results showed that PH group versus control group had higher pulmonary arterial pressure (PAP) and wall thickness index (WTI) 21 days after MCT treatment. The expression of phosphorylated (p)-Smad2 and the ratio of p-Smad2/Smad2 were much higher in PH group than in control group. Fluorescence-labeled MSCs were extensively distributed in rats' lungs in VMSCs and TMSCs groups 3 and 14 days after transplantation, but not found in the media of the pulmonary artery. WTI and PAP were significantly lower in both VMSCs and TMSCs groups than in PH group three weeks after MCT injection. The p-Smad2 expression and the ratio of p-Smad2/Smad2 were obviously reduced in VMSCs and TMSCs groups as compared with those in PH group. In conclusion, both intravenous and intratracheal transplantation of MSCs can attenuate PAP and pulmonary artery remodeling in MCT-induced PH rats, which may be associated with the early suppression of Smad2 phosphorylation via paracrine pathways.

Under the"Internet +" era, some medical staff' s treatment philosophy cannot adapt to the current situation, and patients are prone to produce high expectations because of inadequate basic medical knowledge and the habit of acquiring medical information from Internet. However, when the difference between reality and expec-tations are large, they might be in disputes with medical staffs, and coupled with the lag of hospital management, the doctor-patient communication often is not smooth situation. Therefore, it is recommended that medical staffs improve humanistic quality meanwhile improving technology, patients should develop the habit of acquiring medical information from Internet correctly, hospital needs to optimize management and allocate medical resource reasona-bly, and society should also create positive atmosphere.

Nowadays,the one hospital with multiple districts has become a common model for the development of large public hospitals at present.Through the analysis of the common problems in the development of one hospital with multiple districts,the homogeneous management of one hospital with multiple districts has practical problems,it reflected in difficulties in space management,difficulties,difficulties in staff management,difficulties in system management,difficulties in collaborative development of medical service,difficulties in assessment,difficulties in cost management,difficulties in culture integrations.The case of the scientific management of one hospital with multiple districts in a tertiary public hospitals of provincial state-owned is analyzed,the experience are summarized in terms of organizational structure level,development orientation level,personnel level,performance pay level,cost control level,basic facilities level,culture level,to expected to provide references for promoting the construction of one hospital with multiple districts in public hospitals.
