OBJECTIVETo explore the effects of qianggu capsules (QGC) on the fracture healing and the bone mineral density (BMD) in radius distal osteoporosis fracture (RDOF) patients.

METHODSBone mineral density (BMD) of femoral neck in 65 patients with RDOF was detected after the fracture was fixed manually. They were then randomly divided into two groups. Thirty-three patients in the treated group took QC, 1 capsule (180 mg) each time, three times a day, while 32 patients in the control group took D-Cal Biocal 2 tablets (1500 mg) each time, once daily. The therapeutic course for both groups was three months. X-ray examination on the broken end of the fractured bone was taken every month to observe the bony callus formation for comparing the curative effect, and BMD of femoral neck were detected again after patients were treated for 3 months. The bony callus appeared earlier, more in volume with thicker cortex in the treated group after 2 months of treatment versus that in the control group. The fracture healing time in the treated group was 9.4 +/- 2.5 weeks and that in the control group was 12.5 +/- 2.9 weeks, showing significant difference between them (P < 0.05). BMD in the treated group before treatment was 0.621 +/- 0.085 g/cm2, which was lower than that after treatment (0.646 +/- 0.090 g/cm2) with significant difference showing between them (P < 0.05), while no significant change of BMD was found in the control group between before and after treatment, and significant difference was found in BMD between the two groups after treatment (P < 0.05).

CONCLUSIONQGC can promote the formation of bony callus ahead of time, increase the volume of bony callus and BMD, improve the bone structure, and thus the time of external fixation in treating RDOF could be reduced.

OBJECTIVETo study the effect of Shenbing Mistura (SM) combined with glucocorticoid on recurrent nephrotic syndrome (RNS) in children and levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) in blood and urine.

METHODSThe treatment group was treated with SM plus glucocorticoid, the control group with glucocorticoid alone, and a healthy control group was adopted, 30 cases in each group. The clinical effect and recurrence rate were observed, and levels of IL-6 and TNF-alpha in blood and urine were determined before treatment and at the 4th, 8th, 12th week after treatment.

RESULTSSignificant difference of IL-6 and TNF-alpha levels in blood and urine was found in either the pre- and post- treatment auto-control of both the treatment group and control group, or in the inter-group comparison of them (P < 0.01); clinical effect also showed remarkable difference between the two groups (P < 0.01). Furthermore, the recurrence rate of the treatment group was lower than that of the control group showed by a 18-month follow-up (P < 0.01).

CONCLUSIONSM combined with glucocorticoid could significantly reduce the recurrence rate and elevate the clinical effect in children with RNS, it could also lower the levels of IL-6 and TNF-alpha in patients' blood and urine.

OBJECTIVETo study the mobilization effects of stem cell factor (SCF) along with granulocyte colony-stimulating factor (G-CSF) on bone marrow stem cells and endothelial progenitor cells in rats with unilateral ureteral obstruction (UUO).

METHODSFifty-six healthy male Wistar rats were randomly divided into seven groups: control, SCF, G-CSF, SCF+G-SCF, Sham-operated, UUO and UUO+SCF+G-CSF groups (n=8 each). The rats from the control, SCF, G-CSF and SCF+G-CSF groups were hypodermically injected with normal saline (2 mL/kg), SCF (200 microg/kg), G-CSF (200 microg/kg) and SCF along with G-CSF respectively for 5 days. The rats from the UUO and UUO+SCF+G-CSF groups were subjected to the ligation of right ureter and then were hypodermically injected with normal saline (2 mL/kg) and SCF (200 microg/kg)+G-CSF (200 microg/kg) respectively for 5 days. The sham-operated group had the same operative approach as the UUO and the UUO+SCF+G-CSF groups but the right ureter was not ligated. After operation they received a hypodermical injection of 2 mL/kg normal saline for 5 days. Five days later blood samples were collected. The percentages of CD34+ and CD34+/CD133+ cells in intravenous blood mononuclear cells were detected by flow cytometry. Serum contents of glutamate-pyruvate transaminase (GPT), glutamic oxalacetic transaminase (GOT), urea nitrogen and creatinin were measured.

RESULTSExcept for the sham-operated group, the other five groups (SCF, G-CSF, SCF+G-SCF, UUO and UUO+ SCF+G-CSF groups) had significantly higher percentage of CD34+ cells and CD34+/CD133+ cells in intravenous blood mononuclear cells than the control group (P < 0.05). There were significant differences in the percentage of CD34+ cells and CD34+/CD133+ cells among the five groups (P < 0.05). The UUO+SCF+G-CSF group showed the highest percentage of CD34+ cells and CD34+/CD133+ cells, followed by the SCF+G-CSF group. There were no significant differences in serum contents of GPT, urea nitrogen and creatinin among the seven groups. Except the UUO group showed higher GOT contents, there were no significant differences in the GOT contents among the other six groups.

CONCLUSIONSThe mobilization effects of SCF and G-CSF on bone marrow stem cells and endothelial progenitor cells were not always in paraller. A combination of SCF and G-CSF can effectively mobilize stem cells and endothelial progenitor cells, and side effects were not found in the liver and the kidney.

OBJECTIVETo evaluate the effect of clearance of superoxide anion by catechin on the expression of nitrogen monoxidum (NO) and endothelial nitricoxide synthase (eNOS) and apoptosis in endothelial progenitor cells (EPCs) induced by angiotensin II (Ang II).

METHODSThe marrow endothelial progenitor cells of Sprague-Dawley rats were isolated and assigned to control (no treatment), Ang II treatment and Ang II + catechin treatment groups. After 48 hrs of culture, the concentration of O2*- in the supernate was measured by the NBT method, and NO concentration in the supernate was measured by the nitrate reductase method; the apoptosis rate of EPCs was detected by the TUNEL method; the mRNA expression of eNOS was detected by RT-PCR; the protein expression of eNOS was detected by Western blot analysis.

RESULTSAng II of 10-6 mol/L was determined as the suitable concentration for cell induction by the MTT test. Catechin of 400 mg/L was determined as an advisable intervention dosage. The apoptosis rate of EPCs in the control, the Ang II and the Ang II+catechin treatment groups were 2.48+/-0.12%, 54.18+/-0.77% and 16.87+/-0.35%, respectively, and there were significant differences among the three groups (P<0.01). The O2*- concentration in the Ang II and the Ang II+catechin treatment groups (81.7+/- 3.6 and 62.3+/- 2.2 U/L respectively) was significantly higher than that in the control group (33.7+/- 2.8 U/L) (P<0.01). An increased NO concentration was also found in the Ang II (189. 8+/- 9.0 micromol/L) and the Ang II+catechin treatment groups (276.4+/- 10.1 micromol/L) compared with that in the control group (105.8+/- 9.8 micromol/L) (P<0.01). There were significant differences in the concentrations of O2*- and NO between the Ang II and the Ang II+catechin treatment groups (P<0.05). The mRNA (P<0.05) and protein expression (P<0.01) of eNOS in the Ang II and the Ang II+catechin treatment groups increased significantly compared with those in the control group. The Ang II+catechin treatment group showed increased eNOS protein expression compared with the Ang II group (P<0.05).

CONCLUSIONSAng II may induce the generation of O2*-, inactivate NO and increase gene and protein expression of eNOS in EPCs. Catechin might decrease the apoptosis of EPCs through the effective clearance of O2*-and the reduction of NO inactivation and of eNOS protein uncoupling.
