Objective To investigate the effect of on serum and urine MCP -1 secretion in patients with Stage IV Type 2 diabetic nephropathy treated by lipoic acid .Methods We enrolled 76 diabetic nephropathy patients ,who were randomly divided into two groups . Patients in group T (24 males and 14 females) were treated by lipoic acid 0.6 gram per day.Those in group C (22 males and 16 fe-males) were treated by routine drugs.The serum creatinine (Scr), urea nitrogen (BUN), fasting blood sugar(FBS) and 24h urinary pro-tein,serum and urine MCP -1 secretion were measured at the experiment onset and 3 weeks later.Results There was no significant difference in the serum creatinine , urea nitrogen, fasting blood sugar, HbA1c between the two groups neither at the experiment onset nor after 3 weeks.Compared to experiment onset , 24h urine protein (Tp/24h), serum and urine MCP-1 secretion were all significantly de-creased (P<0.05) in group T after 3 weeks.Compared to group C (2.41 ±0.91g/24h, 91.45 ±33.41pg/ml, 114.78 ±36.35pg/ml), all the levers in group T (1.89 ±0.72g/24h, 39.50 ±13.68pg/ml, 63.41 ±19.57pg/ml) was significantly decreased (P<0.05) after 3 weeks.There was a positive correlation between the serum , urine MCP-1 levels and Tp/24h (r=0.572, P<0.05;r=0.697,P<0.05).Conclusion Lipoic acid can reduce urine protein excretion in diabetic nephropathy patients , maybe by decreasing serum and u-rine MCP-1 secretion .

Objective:To observe the effect of emotional resilience training on compassion fatigue and psychological resilience of intensive care unit nurses.Methods:A total of 70 intensive care unit nurses were randomly divided into experiment group and control group, each of 35 cases. Control group nurses were given routine psychological guidance intervention, in addition, the experiment group was carried out 8 weeks of emotional resilience training. The effect of intervention was assessed by Chinese version of the compassion fatigue scale and Connor-Davidson resilience scale before and after intervention.Results:After intervention, the average scores of compassion satisfaction, secondary traumatic stress and total compassion fatigue scores were (26.46±4.99)pionts, (17.80±4.05)pionts and (69.14±5.70)pionts, significantly lower than in the control group (28.86±4.14)pionts, (20.11±4.38)pionts and (75.51±10.32)pionts, the difference was statistically significant ( t value was 2.190, 2.296, 3.197, P<0.05). After intervention, the average scores of tenacity, power, optimism and total resilience scores were (34.23±6.06)pionts, (25.77±5.01)pionts, (14.31±3.22)pionts and (74.31±9.55)pionts, significantly higher than in the control group (30.86±6.23)pionts, (23.31±3.29)pionts, (12.11±2.04)pionts and (66.29±7.28)pionts, the difference was statistically significant ( t value was 2.295-3.956, P<0.05). Conclusion:Emotional resilience training can effectively reduce the compassion fatigue and improve psychological resilience of intensive care unit nurses.

Objective To investigate the expression level of CRIF1 in human leukemic Jurkat T-cell line cocultured with primary leukemic bone marrow stromal cells.Methods RT-PCR was used to study the expression level of CRIF1 in human leukemic Jurkat T-cell line cocultured with primary leukemic bone marrow stromal cells in vitro. Results After coculture with leukemic bone marrow stromal cells, the expressions of CRIF1 and Gadd45 mRNA in Jurkat cells were significantly higher than the control.Conclusion High mRNA levels of CRIF1 might be associated with the G0/G1 phage arrest in human leukemic Jurkat T-cell line cocultured with primary leukemic bone marrow stromal cells.

Objective To screen and analyze the differentially expressed genes of Jurkat cells cocultured with bone marrow stromal cells(BMSCs) from leukemia patients.Methods Suppression subtractive hybridization(SSH) was employed to establish subtracted cDNA library of differentially expressed genes in Jurkat cells cocultured with BMSCs from leukemia patients in vitro.The cDNA fragments were sequenced and analyzed.Results The differentially expressed gene cDNA library of Jurkat cells cocultured with BMSCs from leukemia patients in vitro was developed by SSH.Primary screening was done by reverse northern hybridization.Thirty up-regulated and 22 down-regulated cDNA fragments were isolated and sequenced,and sequence homology was performed by BLAST in GenBank.These genes were related to cell cycle regulation,cellular apoptosis and energy metabolism.The information of differentially expressed genes in Jurkat cells implied that their secretion function,cell cycle and apoptosis were affected by BMSCs from leukemia patients.Conclusion BMSCs from leukemia patients might influence gene expression of Jurkat cells.The differentially expressed genes might be significantly associated with the protection of BMSCs from leukemia patients on Jurkat cells during Daunorubicin exposure.

BACKGROUND:There are few clinical control ed trials about the clinical effects in patients with pertrochanteric femur fractures after treatment with short or long proximal femoral nail antirotation.
OBJECTIVE:To compare the clinical outcomes in patients with AO/ASIF-A1/2 pertrochanteric femur fractures after treatment with short or long proximal femoral nail antirotation.
METHODS:A total of 98 patients with AO/ASIF-A1/2 pertrochanteric femur fractures were treated by proximal femoral nail antirotation. They were divided into two groups according to the type of proximal femoral nail antirotation:short nail group (n=50) and long nail group (n=48). The operative time, blood loss, and hospital stay were recorded in both groups. In fol ow-up, fracture healing time, imaging and clinical complications were evaluated. In the final fol ow-up, Harris hip score was used to evaluate functional recovery.
RESULTS AND CONCLUSION:Compared with the short nail group, operative time was shorter and blood loss was less in the long nail group (P<0.05). No significant difference in hospital stay was detected between the short nail and long nail groups (P>0.05). Average fol ow-up periods were respectively (15.8±6.4) months and (16.2±5.7) months in the long nail and short nail groups.“Cutting-out”or infection occurred in five patients in the long nail group and three in the short nail group. Besides above-mentioned patients, the remaining patients in the two groups achieved fracture healing. No significant difference in average fracture healing time was detected between groups (P=0.588). In the final fol ow-up, no significant difference in Harris hip score was detectable in the two groups (P=0.204). The incidence rates of total postoperative complications in the long and short nail groups were 31.2%and 16.0%, respectively (P=0.075). Results suggested that no differences in the union and complication rates between the two groups were identified, suggesting that long nails offer no advantage compared with short nails for stabilizing AO/ASIF-A1/A2 pertrochanteric femur fractures.
