Objective To investigate children′s myelodysplastic hematopoietic cells reaction to interleukin (IL)-15.Methods CD 34 + cells in bone marrow from 18 myelodysplast syndrome(MDS) patients were purified by an immunomagnetic beads sorting system. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and flow cytometric analysis.Results On 8th cultured day,when IL-15 concentration was between 0-100 ng/ml,it could suppress apoptosis of hematopoietic cells in MDS patients in a dose-and- time dependent manner. IL-15 in study group significanthy lower than that of control group.Conclusion IL-15 may partly suppress apoptosis of hematopoietic cells in MDS patients.

OBJECTIVETo compare the difference in the therapeutic effect on lower back myofascitis between the combined therapy of penetration needling on yang meridian of the back and electroacupuncture and the western medication of Ibuprofen capsules, and probe into a better method of treatment for lower back myofascitis.

METHODSSixty cases of lower back myofascitis were randomly divided into two groups. 30 cases in observation group were treated with penetration needling combined with electroacupuncture on the back shu points on the first line of the Bladder Meridian and the points of the corresponding levels on the Governor Vessel. 30 cases in control group were treated with Ibuprofen capsules. The treatment session was 30 days. The therapeutic effects were compared and the Visual Analog Scales (VAS) and Oswestry disability index were detected before and after treatment in two groups separately.

RESULTSThe total effective rate in observation group was 96.7% (29/30), which was superior to that (73.3%, 22/30) in control group. VAS and Oswestry disability index decreased in either group (P < 0.01, P < 0.05). The improvement extent in observation group was superior to that in control group (P < 0.05).

CONCLUSIONThe therapy of penetration needling on yang meridian of the back combined with electroacupuncture has the advantageous therapeutic effect on lower back myofascitis as compared with the medication of Ibuprofen capsules, which can release pain and improve the functional disturbance effectively.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

Objective To study the expression and the relation of vascular endothelial growth factor (VEGF)and matrix metal proteinase-2(MMP-2)in rectal cancer and evaluate their roles in rectal carcinogen- esis and development.Methods The expression of VEGF and MMP-2 in 52 cases of rectal cancer was de- tected by immunohistochemical SP technique.12 cases normal rectal tissue served as the control group.Re- suits The expression of VEGF in rectal carcinoma(67.3 %)was much higher than that in control group(P

AIMThe relationship between gastric acid secretion and ATP level, and regulation of uncoupling protein 2 (UCP2) mRNA expression by vagus nerve were studied in vagotomies rats.

METHODSWith the high selective vagotomy model, the gastric acidity was titrated to pH 7.0 with 0.1 mol/L NaOH solution and ATP contents were quantified by using fluorimetry. The expression of UCP2 mRNA was observed by using Northern blot in stomach of rats.

RESULTSBoth of gastric acidity and ATP contents in stomach body decreased significantly at 24 h after vagotomy. The expression of UCP2 mRNA was markedly increased as compared with sham operation group.

CONCLUSIONATP contents decreased and vagus nerve down-regulates expression of UCP2 mRNA in stomach corpus in vagotomies rats. The results indicates that vagus nerve could underlay the gastric acidity by inhibiting expression of UCP2 mRNA and increasing ATP contents in rats.

AIMTo investigate the protective effects of glucagon-like peptide 2(GLP-2) on intestinal ischemia/reperfusion (I/R) injury in mice.

METHODSIntestinal ischemia/reperfusion model in mice were set up and 32 mice of Kunming species were divided randomly into 4 groups (n=8): Sham group, I/R group, I/R + GLP-2 group and I/R + glutamine group. The morphologic changes of intestinal mucosa were observed under LM. The villus height and crypt depth of intestine, the activity of diamine oxidase (DAO) in intestine and bacterial translocation rates of mesenteric lymph nodes (MLN) were detected.

RESULTSCompared with sham operation group, the intestinal villi were sloughed in I/R group with decreased villus height and crypt depth (P < 0.01), the DAO activities were decreased (P < 0.01), and MLN bacterial translocation rates were increased (P < 0.05). While GLP-2 administration improved the villus damage, increased DAO activity (P < 0.01), and decreased MLN bacterial translocation rates (P < 0.05), compared with I/R group.

CONCLUSIONGLP-2 have protective effects on intestinal morphology and barrier function after ischemia/reperfusion injury in mice.

OBJECTIVETo compare and evaluate the effect of autologous cancellous bone and cancellous bone enriching bone marrow stem cell for the repairing the defects of articular cartilage, and purpose the experimental basis for clinical application.

METHODSBy using the completely random design, 16 adult rabbits were divided into two groups randomly. Autologous cancellous bone and cancellous bone enriching bone marrow stem cells were applied for repairing size-matched, full-thickness articular cartilage defects on the femoral condyle of the knees. The reconstructed tissues were observed by gross, optical and microscopy view and Wakitani score at 12 weeks respectively.

RESULTSIn cancellous bone enriching bone marrow stem cells group, articular surface was ivory white and relative evenness, the regenerated tissues integrated well with the surrounding normal cartilage with obscure boundary between them. The thickness of regenerated tissues was two-third of normal cartilage, the Wakitani score was 4.44 +/- 1.41. In autologous cancellous bone group, articular surface was gray and introcession, the regenerated tissues was very thin, the thickness of regenerated tissues was one thirds or one half of normal cartilage, the Wakitani score was 8.93 +/- 1.18. The differences between two groups were significant (P < 0.01).

CONCLUSIONCancellous bone enriching bone marrow stem cells are feasible for repairing of large articular cartilage defects with hyaline cartilage. The repairing ability of autologous cancellous bone is inferior.
