Citing the IT development of the General Hospital of Nanjing Military Region at Fuzhou as an example, the authors point out that emphasizing the role of the people and doing a good job of talent planning and cultivation is the key to the IT development of a hospital. They argue that a hospital must have leaders and managers that stress the IT development of the hospital; it must have a team of people with high IT expertise; it must have a large number of staff very familiar with the operation of the computer; and it must be able to integrate its human resources and give play to the overall efficiency.

Hyperhomocysteinemia is an important independent risk factor for cardio-cerebrovas- cular diseases.Studies in recent years have suggested that hyperhomocysteinemia is also an independent risk factor for vascular dementia and Alzheimer's disease.Mild vascular cognitive impairment is the prophase of vascular dementia.Mainly through the damage of vascular wall structure and its function,homocysteine may has correlation with mild vascular cognitive impairment.

Objective To investigate the diffusion-weighted imaging (DWI)characteristics and the correlation of diffusion coeffi-cient (ADC)and differentiation grade of rectal tubular adenocarcinoma.Methods The DWI characteristics of thirty-eight patients pathologically comfirmed rectal tubular adenocarcinomas were evaluated respectively.There were 9 highly differentiated tubular ade-nocarcinomas,1 5 moderately differentiated tubular adenocarcinomas and 14 poorly differentiated tubular adenocarcinomas.The ADC value was calculated from two different factors (0 and 1 000 s/mm2 ).The correlation between ADC value and the differentiated de-gree of tumour was statistically analysed.Results The mean ADC for highly differentiated group was (0.92±0.05)×10 -3 mm2/s, and the mean ADC for moderately differentiated group was (0.79 ± 0.10)× 10 -3 mm2/s whereas that for poorly differentiated group was (0.71±0.06)×10 -3 mm2/s.The difference among three groups was statistically significant(P <0.05).The ADC value and the differentiated degree of tumour were negatively correlated(Spearman r =-0.704)P<0.01.Conclusion DWI and ADC value can be a useful estimating for the differentiation of rectal tubular adenocarcinoma.

OBJECTIVETo investigate the differences in the expressions of E-cadherin and N-cadherin between high-risk prostate cancer and low- and medium-risk prostate cancer, and analyze their correlation with the age, serum PSA level, and Gleason score of the patients.

METHODSWe retrospectively analyzed the clinical data of 42 cases of prostate cancer, which were divided into a low- and medium-risk group (group A, n = 15) and a high-risk group (group B, n = 27). We measured the expressions of E-cadherin and N-cadherin by immunohistochemical staining, compared their differences between the two groups, and analyzed their correlation with the age, serum PSA level, and Gleason score of the patients.

RESULTSImmunohistochemical staining showed that the expression of E-cadherin was significantly higher in group A than in B (6.1 +/- 0.51 vs 4.2 +/- 0.37, P < 0.01), and so was its positive rate (73.3% vs 25.9%, P < 0.05). The positive rate of E-cadherin was also markedly higher in the patients with serum PSA < 20 microg/L than in those with serum PSA > or = 20 microg/L (66.7% vs 29.6%, P < 0.05), and so was it in the patients with the Gleason score 5-7 than in those with 8-10 (60.9% vs 21.1%, P < 0.05). On the contrary, the N-cadherin expression was significantly lower in group A than in B (3.7 +/- 0.32 vs 7.5 +/- 0.58, P < 0.01), and so was its positive rate (13.3% vs 59.3%, P < 0.01). The positive rate of N-cadherin was also remarkably lower in the patients with the Gleason score 5-7 than in those with 8-10 (26.1% vs 63.2%, P < 0.05). However, there were no statistically significant differences in the N-cadherin expression between the patients with serum PSA < 20 microg/L and those with serum PSA > or = 20 microg/L (P > 0.05), nor in the expressions of E-cadherin and N-cadherin between the patients aged > or = 70 years and those aged < 70 years (P > 0.05).

CONCLUSIONThe expressions of E-cadherin and N-cadherin are significantly different between high-risk prostate cancer and low- and medium-risk prostate cancer, which suggests that both may correlate with the invasion and metastasis of prostate cancer as well as with the serum PSA level and Gleason score of the patients.

The free radical scavenging effect of flaxseed was screened by HPLC-DPPH ( 2 , 2-diphenyl-1-picrylhydrazyl-high performance liquid chromatography assay ) and colorimetric DPPH methods. To test the effectiveness of the approach, three Lignans ( secoisolariciresinol diglucoside ( SDG ) , secoisolariciresinol ( SECO) and enterodiol( ED) ) with antioxidative properties were investigated both in monomer and mixture. HPLC conditions were optimized using following methods: Waters XBridge C18 was used as stationary phase, acetonil/H2 O was used as mobile phase and detective wavelength was set at 280 nm. Antioxidant activity of standards was investigated by reaction with or without DPPH radical for 20 min as sample and control, respectively. Both of them were analyzed by high performance liquid chromatography. According to the changes of amount of sample and control, the antioxidant activities of standards were calculated as following order:SDG>SECO>ED. Based on above DPPH-HPLC assay and UPLC-Q-TOF-MS, antioxidants extracted from flaxseed were separated, identified and screened. The radical scavenging activities were in the following order:SDG isomer (5)>SDG (4)>7α-[(β-D-glupyranosyl) oxy]-1-methoxyisolariciresinol (1)>(6R,7R, 8S)-1-methoxyisolariciresinol (2)>herbacetindiglucoside (3). It indicated that the HPLC-DPPH assay could be successfully used for the antioxidant activity screening of complex flaxseed extract.

BACKGROUND:Longbie Capsule has satisfactory outcomes in the treatment of osteoarthritis, but its mechanism is stil unclear.
OBJECTIVE:To study the effect of Longbie Capsule on proliferation of bone marrow mesenchymal stem cel s. METHODS:The bone marrow mesenchymal stem cel s from SD rats were separated and expanded by whole adherence culture, then subcultured and confirmed by morphological observation and flow cytometry. Passage 4 cel s were cultured in complete media containing 5 g/L, 1 g/L, 250 mg/L, 50 mg/L, 10 mg/L Longbie Capsule, respectively, for 24 hours. Then, MTT assay was used to detect cel viability.
RESULTS AND CONCLUSION:The primary cel s were adherent cel s characterized by irregular shape, passage 2 cel s were typical y fibrous-shaped, passage 3 cel s grew in long fibrous and swirl-type shape. Passage 4 cel s were strongly positive for CD29 and CD90, positive for CD44, and negative for CD34 and CD45. 5 g/L and 1 g/L Longbie Capsule promoted the proliferation of bone marrow mesenchymal stem cel s. These findings indicate that Longbie Capsule may promote the proliferation and differentiation of bone marrow mesenchymal stem cel s, thereby playing a therapeutic effect on osteoarthritis.

Objective To investigate the relationship of the serum level of IL-23 and MMP-9 with the clinicopathologic features in patients with esophageal squamous cell carcinoma (ESCC). Methods 48 pathologically confirmed ESCC patients and 30 Endoscopic biopsy of benign were included in this study. The serum levels of IL-23 and MMP-9 were examined by enzyme-linked immunosorbent assay (ELISA). Results Serum IL-23 level in patients with ESCC was significantly higher than that in controls (t = 26.66, 16.89, P<0.05). Furthermore, Pearson′s correlation analysis revealed that serum IL-23 was positively correlated with the serum MMP-9 level in ESCC patients (r = 0.790, P < 0.05). Statistical analysis showed that enhanced serum IL-23 significantly correlated with the degree of differentiation and lymph node metastasis. Conclusion Overexpression of IL-23 may involve in the occurrence and development of ESCC. IL-23 may contribute to tumorinvasion and metastasis by stimulating the expression of MMP-9.

Objective To investigate the factors related to death of thoracic trauma emergency in children.Methods Total 528 children and infants aged 0-14 years with thoracic injuries , including 317 boys and 211 girls, admitted in emergency department from January 2010 to January 2014 were included in the study.The factors related to emergency death were investigated by using conditional logistic analysis.Results Among 528 cases, emergency death occurred in 34 cases with an emergency mortality rate of 6.44%.Single-factor analysis showed that emergency death was correlated with complication with other organ trauma, the time of first medical intervention , the time of arriving at first contact hospital , the rank of first contact hospital , hypoxemia and causes of injuries ( all P<0.05 ); however , not correlated with the gender, age, of patients, areas of residence, family economic status and seasons of injury occurring (all P>0.05).Logistic analysis showed that the time of first medical interventio n>30 min ( B=1.467,95%CI:0.412-0.975), complication with other organ trauma (B=2.342,95%CI:0.415-0.943), hypoxemia (B=2.915,95%CI:0.749-0.819), and first visiting to tertiary hospital (B=-1.861,95%CI:1.023-1.742) were influencing factors of emergency death.Conclusion The results indicate that to improve the success rate of emergency treatment of thoracic trauma in children , it is necessary to reduce the time of first medical intervention and to correct the hypoxemia promptly.
