Objective To observe the effect of type 2 diabetes mellitus on serum platelet-derived endothelial cell growth factor (PD-ECGF) and vascular endothelial growth factor (YEGF) in patients with acute cerebral infarction.Methods Seventy-three patients with acute cerebral infarction (32 patients with non-concomitant diabetes were assigned to group A,and 41 patients with diabetes were assigned to group B),30 cases of type 2 diabetes mellitus patients with non-cerebrovascular disease hospitalized in the same period (group C),and 30 patients without cerebrovascular disease and diabetes mellitus (group D) were the subjects.The serum levels of PD-ECGF and VEGF in group A and group B were measured at 1,3,7,10 to 14 days after onset by double antibody sandwich enzyme-linked immunosorbent assay,which in group C and group D were measured at 1 st day..NIHSS scores were performed on group A and group B using the NIHSS Score (NIHSS) scale.Results The levels of PD-ECGF in group A were (5.93 ± 1.25),(5.93 ± 1.25),(4.19 ± 1.23),(3.67 ± 1.06) μg · mL-1,at 1,3,7,10 to 14 days after onset,The levels of PD-ECGF in group B were (2.88 ±0.54),(2.84 ±0.53),(2.81 ±0.41) and (2.86 ± 0.49) μg · mL-1.The VEGF levels in group A were (172.32 ± 31.91),(158.91 ± 31.84),(158.69 ± 29.27),(156.92±38.16),(159.64 ±27.21) and (159.91 ±40.25) pg· mL-1,The levels of VEGF in group B were (154.91 ±31.84),(158.69 ±29.27),(156.92 ±38.16),(159.64 ±27.21) pg · mL-1,the differences were statistically significant (all P ＜ 0.05).On the first day of admission,the PD-ECGF of group C and D were (2.25±0.49),(2.79±0.51) μg·mL-1,the VEGF were (94.90±19.85),(151.11±130.33) pg· mL-1,the differences were statistically significant (all P ＜ 0.05).The scores of NIHSS in group A and group B were (12.52 ±3.25) and (12.89 ±2.56).The difference was not statistically significant (P ＞ 0.05).On the 10 th to 14th day after onset,the NIHSS scores of group A and group B were (6.48 ± 2.15) and (4.24 ± 1.87) respectively,the difference was statistically significant (P ＜ 0.05).Conclusion Type 2 diabetes can reduce the expression of PD-ECGF and VEGF in patients with cerebral infarction and affect the prognosis of patients with type 2 diabetes mellitus.

Exosomes are membrane vesicles secreted by cells into the extracellular environment. Exosomes are a new cell component in the treatment of spinal cord injury. Exosomes are secreted by mesenchymal stem cells have anti-apoptotic, anti-inflammatory and pro-angiogenic effects in the treatment of spinal cord injury, which play a key role in nerve cell-cell communication and can delivery exogenous genetic material. Exosomes can penetrate blood-brain barrier and are more stable than their parent cells, reducing the safety risks in the administration of viable cells.

This study was aimed to evaluate the therapeutic efficacy of bortezomib combined with autologous peripheral blood hematopoietic stem cell transplantation (autoPBSCT) for patients with multiple myeloma (MM). 5 patients underwent autologous hematopoietic stem cell transplantation. Bortezomib treatment was supplied for patients before autoPBSCT and in the conditioning of transplantation, it was also used in maintaining treatment. Patients with transplantation adopted bortezomib plus melphalan conditioning regimen. The number of infused MNC and number of CD34(+) cells were 4.06×10(8) (4.09×10(8) - 4.37×10(8))/kg and 3.98×10(6) (2.49×10(6) - 8.2×10(6))/kg respectively. The results showed that hematopoiesis was reconstituted in 5 patients, with a neutrophil cell count more than 0.5×10(9)/L at day 14 (13 - 25 days) after transplantation and platelet count more than 50×10(9)/L at day 28 (21 - 41 days) after transplantation. Transplantation-associated death was not observed. 5 patients were disease-free survival. In conclusion, treatment of bortezomib combined with autologous peripheral hematopoietic stem cell transplantation is an effective method for patients with multiple myeloma. Use of bortezomib after transplantation might still be favourable to MM patients, for survival prolongation and life quality improvement.

OBJECTIVETo detect the effect of Nocardia rubra cell wall skeleton (Nr-CWS) on tumorigenicity induced by TC-1 cells and to clinically study anti-human papillomavirus effect of Nr-CWS in lower genital tract of women.

METHODSTumor model was established by injecting TC-1 cells subcutaneously in SCID mice, then divided them into 3 groups randomly and injected with isovolumetric physiological saline, 60 micrograms/ml Nr-CWS and 120 micrograms/ml Nr-CWS respectively, the growth of tumors was measured one week later. Nr-CWS was applied on 45 HPV positive women whose TCT test was normal and without cervical erosion 2-3 days after menstruation. HPV was detected again 3 months later to explore the effect of Nr-CWS on HPV infection in female lower genital tract.

RESULTSThe animal experiment showed the weight of transplanted tumors in treated group was less than that of control group (chi2=12.5, P= 0.002). The tumor inhibition rate was 59.1 percent and 84.2 percent in the groups treated with Nr-CWS 60 and 120 micrograms/ml Nr-CWS; the results of HPV detection in 23 out of the 45 cases (51.1 percent) became negative after the 3-month treatment; the viral load was reduced in 9, and there was no change in viral load in 13 cases. Significant difference was found between the rates of undetectable viral load and the natural viral disappearance rate (P less than 0.05).

CONCLUSIONNr-CWS has an inhibitory effect to TC-1 cell tumorigenesis and clinical application of Nr-CWS may eliminate the HPV infection in lower genital tract of a considerable proportion of women with HPV infection.

OBJECTIVETo study the association of vertical facial skeletal types and sagittal facial skeletal types with anterior alveolar bone thickness.

METHODSAmong 168 cases with malocclusion in early permanent dentition stage, 93 patients were male and 75 patients were female. All patients (aged 10-14 years) were divided into 9 groups by different facial skeletal types, mandibular anterior alveolar bone thickness in patients' lateral cephalometric films were measured. ANOVA were performed to measurement results with the SPSS 13.0 statistical software.

RESULTSThough sagittal facial skeletal types were the same, there were significant differences between different vertical facial types groups. The order was low-angle group, average-angle group and high-angle group according to the size. A high-angle individual often had a thin anterior alveolar bone while a low-angle individual often had the opposite morphology character. There was no statistical significance between skeletal type I, II and III. But group of skeletal type III also had a thin alveolar bone thickness which had no significant difference with high-angle group. Low-angle group III had no significant difference with average-angle group I and II in alveolar bone thickness.

CONCLUSIONSagittal facial skeletal types have little influence on anterior alveolar morphology, but the vertical facial skeletal types have strong connection with anterior alveolar bone thickness.
