Objective To establish the separation and expansion method of human umbilical cord derived mesenchymal stem cells (hUCMSCs) and explore the influence of 1,25 (OH)2VD3 on hUCMSCs in vitro.Methods UCMSCs were cultured from adherent tissue pieces and detected by immunohistochemistry.Taking the third generation with good growth state UCMSCs make intervene experiment.Set 10-7 mol/L,10-9mol/L and 10-11 mol/L 3 kind of concentration of 1,25(OH)2VD3 as the experimental group,and a control group (DMEM medium).The morphologic change of UCMSCs was observed by inverted microscope.Observe the cell proliferation by the method of MTT.Detect alkaline phosphatase assay and type Ⅰ collagen assay from immunohistochemistry.And the calcium tubercle formation would be examined after 21 days.Results UCMSCs were cultured from adherent tissue pieces and strongly positive for CD44,CD105 and negative for CD34,CD45.consistent with the hUCMSCs characteristics.Under different concentration of 1,25 (OH)2VD3hUCMSCs proliferation were promoted within 7 days but were suppressed beyond 7 days.The high doses group ( 10-7 mol/L group ) obvious inhibitted the stem cell proliferation.Different concentrations of 1,25 (OH)2VD3 and days have interactive effect (P ＜ 0.05).The differences between different groups with ALP and type Ⅰ collagen assay has statistical difference (P ＜ 0.05).The secretion of ALP and type Ⅰ collagen assay of 10-7 mol/Lconcentration group was higher than others.Typical mineralization nedus was found in intervene groups.Conclusion HUCMSCs can be successfully cultured from the adherent tissue pieces.1,25(OH)2VD3 can effectively induce hUCMSCs to differentiate into osteoblasts in vitro.

Objective To investigate the test-retest reliability and inter-rater reliability of the Fugl-Meyer assessment (FMA),Wolf's motor function test (WMFT),the box-block test (BBT) and the nine-hole peg test (NHPT) in assessing the upper limb motor function of stroke patients.Methods Eighteen stroke patients participated in the study.Each patient was assessed twice within 2 hours with the U-FMA,WMFT,the BBT and the NHPT.Two raters recorded each session separately.Test-retest reliability was investigated by comparing the assessment results of different sessions; interrater reliability was identified by analyzing the assessment results of different raters.Results The intraclass correlation coefficients (ICC) for the U-FMA were 0.988 on test-retest reliability and 0.959 on inter-rater reliability.The ICC of WMFT by mean and median time were respectively 0.996 and 0.393 on test-retest reliability and both 1.000 on inter-rater reliability.The ICC of WMFT by score mean was O.989 for test-retest reliability and 0.977 for inter-rater reliability.The ICC for test-retest reliability of the BBT using affected hand counts and the difference in counts between the affected and un-affected hand were respectively 0.975 and 0.982.The ICC of the NHPT using affected hand times and the difference between the affected hand and unaffected hand times were respectively 0.937 and 0.936 for test-retest reliability,and both 1.000 for inter-rater reliability.Conclusion The U-FMA,WMFT,the BBT and the NHPT are all measurements with good test-retest reliability and inter-rater reliability.They are reliable for assessing the upper extremity motor function of stroke patients.

Objective To investigate the etiological factors and treatment of thoraco-gastric perforation (TGP) after esophagogastrostomy. Methods Retrospective analysis was carried out in 16 patients with thoraco-gastric perforation after esophagogastrostomy in our department from March 1974 to March 2004. The etiological factor, clinical feature, experiment test and the method of treatment were compared between TGP and patients of thoracic esophageal anastomosis leak (TEAL). Results Thoraco-gastric perforation occurs within 2～5 days postoperatively. Among these 16 cases, in 8, local necrosis of gastric wall was found which was caused by severe contusion and massive ligature. In 5, were penetrative injury of gastric wall caused by suture needle. In 3,unsuitable purse-string suturing of corner of greater or lisser gastric curvature. Hydropneumothorax occurred after thoraco-gastric perforation. Chest fluid was brown and turbid with putrefactive odor. With medium examination, anastomosis was normal, but medium and air bubbles were found outside of the stomach. Perforation were repaired and covered by pedicle tissue-flap in all cases. 15 cases were cured with no sequence. Conclusion TGP after esophagectomy were correlated with technique of surgery. TGP often occurs early after esophagogastrostomy. Transthoracic repairing of TGP should be done as soon as possible. The healing ratio of reparation was about 93.8%.

To investigate the effects of basic fibroblast growth factor (bFGF) on intracellular free Ca 2+ of heating injury, and observe the relationship between mitogen activated protein kinases(MAPKs)signal pathways and Ca 2+ mobilization. Cultured human fibroblasts were heated at 45?C for 10min, then divided into four groups :①basic fibroblast growth factor (10ng/ml) treatment; ②preincubated cells with PD98059 (10?mol/L) for 30 min followed by bFGF (10ng/ml); ③preincubated cells with SB203580 (10?mol/L) for 30min followed by bFGF (10ng/ml); ④preincubated cells with PD98059 (10?mol/L) and SB203580 (10?mol/L) for 30min followed by bFGF (10ng/ml). The cells were incubated with fluorescence Ca 2+ dye fluo 3/AM at 37 C for 30min, then measured by using laser scanning confocal microscope. The results showed fluorescent intensity of fibroblast heating injury was weak, the concentration of intracellular free Ca 2+ increased after stimulation with bFGF treatment. PD98059 and SB203580 could induce calcium oscillation. A rapid decrease of fluorescent intensity was observed after cells were preincubated with PD98059 and SB203580 at the same time. bFGF induced an increase of cytoplasmic and intracellular free Ca 2+ concentrations. It is suggested that MAPKs signaling pathway has a feedback regulation for free Ca 2+ mobilization.

To explore the activities of signal transduction pathway involved in heat-stressed fibroblast in vitro. Human dermal fibroblasts were cultured in Dulbecco′s modified Eagle′s medium with 5% calf serum at 5%CO 2 in a water-saturated atmosphere. Cultured cells were heated to 45℃ for 10min. Western blotting was used to detect ERK1/2 and JNK expression, and the expression of caspase-3 protein was observed by immunoflurescence technique. The results showed that the MAPKs signal transduction pathway was activated in heat-stressed fibroblasts. The expression of JNK reached the peak at 60min, then maintained up to 180min. The expression of ERKs peaked at 30min, then lowered. The expression of caspase-3 was weak at 30min after heat-stress, and became evidently strong at 60min. The signal pathway of ERKs and JNK played important roles in the changes in biologic characteristics of fibroblasts after heat-stress.

0.05).Conclusion The expression of TM in different TCM syndromes of gastric carcinoma was different.There exists a certain relation in the expression of TM1 and TM2 in different TCM syndromes of gastric cancer.

OBJECTIVE:To study the absorptive effect of activated carbon and desorptive effect of organic solvent on endotoxin.METHOD:The effect of different pretreatment modes,time,temperature,amount of activated carbon as well as treatment time on the absorptive effect of activated carbon were analyzed using limulus reagent test.Different organic solvents and treatment time were used to study the desorptive effect of organic solvent on endotoxin.RESULTS:Activated carbon was treated by high temperature baking or adding 0.5 mol?L-1 NaOH represented same effect in removing endotoxin.It showed that optimal time for absorption of endotoxin was 12 min and the amount of activated carbon was at 1.5%.The absorptive effect was similar under condition of room temperature and 37 ℃.The best effect of desorption achieved by using 75% alcohol as desorption reagent after 8 minutes of shaking.CONCLUSION:The activated carbon could be used to absorb endotoxin effectively under suitable conditions and organic solvent could be used to desorb endotoxin from activated carbon.
