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.

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.

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.

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.

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 prognostic factors regarding overall survival in locally advanced stage of esophageal squamous cell carcinoma (ESCC) patients after receiving concurrent chemoradiotherapy (CRT).Methods Each of 80 patients with locally advanced ESCC was treated by doxtel 135-175 mg/m2 d1 and cisplatin 40 mg/m2 d2,3 combined with radiotherapy 60 Gy.ECOG (0-1),tumor locations,tumor sizes,TNM classifications as well as the levels of CA199,SCC-Ag were detected before concurrent treatments and 4 weeks after treatment.The relationship wasanalyzed between the prognosis of disease and CA199,SCC-Ag levels.Each index was studied by Cox statistical regression analysis and P value was determined.Results All patients had completed 4 cycles' treatments successfully.The major adverse effects included neutrophilic granuloaytopenia,calvities,nausea,emesis and diarrhea.The severe effect was Ⅲ degree neutrophilic granuloaytopenia for 2 cases (2.5 ％),all the side-affect had recovered after symptomatic treatments.The median survival time were 50 months and 72.5 months in the patients who were greater than 60 year-old and less than or equal to 60 year-old,respectively (P =0.004).Regarding to 5-year overall survival,the figures were 73.3 ％,69.4 ％,41.7 ％ and 0 in the patients with cT1-2N1M0,cT3N1M0,cT4NoM0 and cT4N1M0 classification,respectively (P =0.024),they were 42.9 ％,70.0 ％,and 60.9 ％ in the patients with upper thoracic esophagus,middle thoracic esophagus,and lower thoracic esophagus,respectively (P =0.971),they were 100 ％ in the patients with ECOG 0 and 54.1％ in the patients with ECOG 1 (P =0.044),they were 86.7 ％ in the patients with CA199≤37 kU/L,and 52.0 ％ in the patients with CA199 more than 37 kU/L (P =0.008),they were 95.5 ％ in the patients with SCC-Ag≤ 1.9 μg/L,and 53.4 ％ with ＞1.9 μg/L (P =0.012).Conclusion For ESCC patients treated with CRT,the age,TNM stage,ECOG,CA199 and SCC-Ag levels are independent forecasting factors regarding their overall survival.
