The theory of "equal stress on bones and muscles" emphasizes that "the tendons bind to the bones, the bones are stretched, the bones are connected, and the bones are fractured. The relationship between bone and soft tissues are important, which is the law of Traditional Chinese Medicine in the treatment of orthopedic diseases. For patients with lumbar disc herniation, the percutaneous intervertebral foraminal technology remodels the disordered internal biological balance of the spine under pathological conditions. Among them, two common clinical minimally invasive approaches under endoscopy are paid attention to soft tissue protection, and active and appropriate functional exercises after surgery, which have become a typical manifestation of the theory of "equal stress on bones and muscles" in modern spinal orthopedic surgery.

The dynamic or flowing tumor cells just as leukemia cells and circulating tumor cells face a microenvironment difference from the solid tumors, and the related targeting nanomedicines are rarely reported. The existence of fluidic shear stress in blood circulation seems not favorable for the binding of ligand modified nanodrugs with their target receptor. Namely, the binding feature is very essential in this case. Herein, we utilized HSPC, PEG-DSPE, cholesterol and two

Objective To investigate the relatio nship between the DNA methylation status of gluco-corticoid receptor (GR) gene promoter and mRNA expression level of GRα gene of peripheral blood mononuclear cells (PBMCs) in patients with systemic lupus erythematosus (SLE). Methods Fifteen new onset SLE patients and fifteen healthy controls were enrolled in this study. The DNA methylation status of GR gene promoter 1 of PBMCs was detected through bisulfite sequencing polymerase chain reaction (PCR). The mRNA expression of GRα, DNA methyltransferases, growth arrest and DNA damage-induced 45α (GADD45α) of PBMCs was detected using the quantitative real-time polymerase chain reaction method. T-test and χ2-test were used to detect the differences between the two groups, Pearson's correlation coefficient was used to analyze the linear correlation between two variables. Results Compared with healthy controls, the mRNA expression of GRα was signi-ficantly declined in SLE patients (10±5, 17±7, t=2.69, P<0.05), and the mRNA expression of DNMT1 and GADD45α was significantly elevated in SLE patients (t=3.11, P<0.05 and t=2.98, P<0.05). The overall mean methylation status of the 142 CpG islands of the four promoters was significantly elevated in SLE patients [(16±8)%vs (11±6)%, t=2.75, P<0.05]. The global methylation status of PBMCs in SLE patients was obviously lower than healthy controls (t=4.39, P<0.05). Conclusion Hypermethylation of GRα promoter may result in GRαgene low expression in PBMCs of patients with SLE.

AIM:To investigate the effects of celecoxib on viability , apoptosis and autophagy in acute myeloid leukemia (AML) cell lines HL-60 and HL-60A.METHODS:The HL-60 cells and HL-60A cells were cultured with vari-ous concentrations (0, 20, 40, 60, 80 and 100μmol/L) of celecoxib.The inhibitory effect of celecoxib on the cell viabil-ity was evaluated by MTT assay .Apoptosis was analyzed by Annexin-V/PI staining.Apoptosis-related and autophagy-relat-ed proteins were determined by Western blot .RESULTS:IC50 of celecoxib were 49.4 μmol/L, 32.0 μmol/L and 25.1μmol/L for HL-60 cells treated with celecoxib for 24 h, 48 h and 72 h, respectively.For HL-60A cells, the corresponding IC50 were 69.1 μmol/L, 42.5 μmol/L and 29.6 μmol/L, respectively.The results of flow cytometry analysis showed the proportions of Annexin-Ⅴ+PI-, Annexin-Ⅴ+PI+and Annexin-Ⅴ-PI+cells were increased in the HL-60 cells, and those of Annexin-Ⅴ+PI-and Annexin-Ⅴ+PI+cells were increased in the HL-60A cells treated with celecoxib for 24 h. After treated with celecoxib , the induction of apoptosis was observed , the apoptosis-related proteins cleaved caspase-3 and cleaved PARP were upregulated , the autophagy-related proteins LC3 II and P62 were both increased , and mTOR, p-mTOR, 4-EBP and p-4-EBP were not changed , indicating that celecoxib inhibited autophagy in the AML cells without the mTOR pathway involvement .CONCLUSION:Celecoxib inhibits the viability of HL-60 cells and HL-60A cells in a time-and dose-dependent manner by its effects of inducing apoptosis and necrosis .Celecoxib inhibits mTOR-independent autoph-agy in AML cells, indicating a possible way of using celecoxib for enhancing the antitumor activity of therapeutic agents to induce cytoprotective autophagy in the AML cells .

BACKGROUND:Because of their immunological properties, bone marrow mesenchymal stem cells transfusion is developed as a new treatment for refractory graft-versus-host disease. OBJECTIVE:To analyze the safety and curative effect of bone marrow mesenchymal stem cells transfusion on treating different organ damages in graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation. METHODS:Eight patients with malignant hematologic disease were included in this study. The patients developed severe steroid-resistant graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation and received transfusion of mesenchymal stme cell(1×106 of immunosuppressive agent. RESULTS AND CONCLUSION:For the total y eight patients, six got response (two cases of complete remission, and four cases of partial remission) and two showed no remission. Four of five cutaneous damages were ameliorated and one showed no effect. For three cases of oral graft-versus-host disease, two acquired complete remission and one showed partial remission. Two cases of liver graft-versus-host disease and two cases of astro-intestinal graft-versus-host disease obtained complete remission. No response was displayed to three cases of ocular graft-versus-host disease, one case of bronchiolitis obliterans, and one case of urinary graft-versus-host disease. In the median fol ow-up of 28 months (7-62 months), three patients developed posttransplant lymphoproliferative disorders within 3 months after mesenchymal stem cells transfusion. Administration of mesenchymal stem cells is safe for treatment of severe graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation. Mesenchymal stem cells transfusion may be a promising/kg) together with the primary therapy therapy for refractory cutaneous , astro-intestinal, liver and oral graft-versus-host disease but not for pulmonary, ocular and urinary graft-versus-host disease. Whether mesenchymal stem cells transfusion is associated with posttransplant lymphoproliferative disorders needs more case data.

ObjectiveTo compare the effects of different surgical approaches on SiewertⅡ (esophageal invasion ≤3 cm) adenocarcinoma of esophagogastric junction.MethodsThis retrospective study included 251 cases of Siewert Ⅱ adenocarcinoma of esophagogastric junction undergoing D2 or D2 + total gastrectomy by transabdominal approach ( TA group, 128 cases) or left thoracoabdominal approach ( LTA group, 123 cases).Operation time,blood loss, extent of esophageal resection, number of lymph nodes dissected,morbidity, mortality and the survival rate were a analyzed between the two groups.ResultsThe 3,5-year overall survival rates were 62. 5％, 39.0％ ( TA group) and 54. 9％, 31.9％ ( LTA group),respectively (P ＞ 0. 05). Length of esophageal resection in the LTA group were slightly longer than that in the TA group (5. 6 ± 1.1) cm vs. (5.4 ± 1.1 ) cm (P ＜0. 05), the positive surgical margin between two groups were not statistically different[1.6％ ( LTA group) vs. 3. 1％ ( TA group), ( P ＞ 0. 05 )]. The mean number of removed lymph node were not significantly different between two groups[23.4 ± 8.7 ( TA group) vs. 23.7 ± 8.4 ( LTA group)], ( P ＞ 0. 05 ). The operation time (227 ± 24) min, blood loss (270 ± 78)ml, and perioperative morbidity( 13.3％ ) and mortality( 1.6％ ) in TA group was significantly better than the LTA group[(261 ±32) min, (342 ±59)ml, 26.8％, 6.5％](P＜0.05).ConclusionsFor Siewert Ⅱ adenocarcinoma at esophagogastric junction (esophageal invasion ≤3 cm) ,total gastrectomy with D2 or D2 + lymph node dissection through the transabdominal approach could achieve curative purposes, with a low morbidity and mortality rate.

Objective To explore the predictive value of microvessel density(MVD)and blood vessel invasion(BVI)in hepatic metastasis from early-stage rectal cancer.Methods MVD and BVI in the tumor tissue from 380 patients with stage I and II rectal cancer was determined by immunohistochemical S-P method with anti-CDIOS antibody and anti-CD34 antibody,respectively.Multinomial logistic regression was performed to analyze the predictive value of MVD and BVI in hepatic metastasis from early-stage rectal cancer.Results CD105 was expressed in newborn blood vessels,not in normal blood veseels.in the rectal cancer tissue.MVD was correlated with histological type and infiltration depth(P＜0.05).Besides histological type and infiltration depth,BVI was also correlated with histological grade.Multivariate analysis revealed that histological type,tumor infiltration depth,BVI,adjuvant therapy,and MDV were independent predictors of hepatic metastasis from rectal cancer.The risk of hepatic metastasis in patients with postive expression of either MVD or BVI or both were significant higher than that in patients with low expression of MVD and those without BVI expression[hazard ratio(95%CI),4.210(2.182-11.214)].Conclusion BVI and MVD are independent predictors of hepatic metastasis from stage I and II rectal cancer.Combined detection of MVD and BVI may help to predict the clinical outcome of patients with early-stage rectal cancer.
