Abstract
Objective: To investigate the curative effect of local application of CpG-oligodeoxynucleotide (CpG-ODN) combined with 4-1BB monoclonal antibody in hepatoma-bearing mice, and to evaluate the effect of 4-1BB monoclonal antibody on CpG-ODN immunotherapy. Methods: H22 single cell suspension was injected subcutaneously into the axilla and four limbs of the BALB/c male mice to establish a tumor-bearing mice model. After 7 days, 30 mice with corresponding tumor-bearing volume were screened and randomly divided into model control group, CpG group and CpG+4-1BB group, and the drug was injected into the tumors of left lower extremity. The same batch of normal mice was selected as normal control group. Survival of mice was recorded. Tumor-bearing volume and organ index were calculated. Serum levels of interleukin (IL) - 12 and interferon (IFN) gamma and spleen CD8(+)T lymphocyte ratio were measured. The measurement data were analyzed by analysis of variance. The survival rate of each group of mice was analyzed by log-rank test. Results: Mice in the model control group with tumor-bearing volume had a sustained growth before the execution. CpG group and the CpG+4-1BB group [(976.08 ± 29.55) mm(3), (47.25 ± 0.93) mm(3))] tumor-bearing volume was decreased than model group [(1 336.52 ± 39.40) mm3] (F = 5 329.273, P < 0.05). CpG+4-1BB group distant tumor-bearing volume [(611.83 ± 113.02) mm3] was decreased than model group and CpG group [(1 406.62 ± 51.09) mm(3), (1 380.01 ± 51.44) mm3] (F = 247.160, P < 0.05), but there was no significant difference between the CpG group and the model group (P > 0.05). Serum IL-12 concentration (23.90 ± 2.33 pg/ml), IFN-γ concentration (103.02 ± 6.10 pg/ml) and spleen CD8(+)T cell ratio (4.54 ± 0.62%) in the model group were lower than those in the normal group (P < 0.05). Serum IL-12 concentration in CpG group and CpG+4-1BB group (29.21 ± 2.23 pg/ml, 37.04 ± 1.49 pg/ml), IFN-γ concentration (116.12 ± 4.08 pg/ml, 138.65 ± 1.72 pg/ml), CD8(+)T cell ratio (6.65 ± 0.64%, 12.73 ± 0.88%) were higher than the model group, while CpG+4-1BB group was higher than the CpG group (P < 0.05). The survival rate of CpG+4-1BB group was higher than that of model group and CpG group (χ(2) = 25.544, P < 0.05), but there was no significant difference between CpG group and model group (P > 0.05). There was no significant difference in organ index between the four groups (P > 0.05). Conclusion: 4-1BB monoclonal antibody combined with CpG-ODN therapy can shrink hepatoma-bearing capacity, inhibit the growth of distant tumors and significantly prolong the survival time of mice.

Abstract
Osteoporosis is a major complication in patients with diabetes mellitus. Thus, it is crucial to study the signal mechanisms responsible for enhancement of bone mass in diabetes. Administration of human parathyroid hormone (hPTH) has been reported to prevent osteoblast apoptosis and have anabolic effects on bone in animals and humans. In the present study, we examined the effects of hPTH on expression of bone morphogenetic protein type 2 (BMP-2) and its receptor BMPR2 in diabetic rats following spinal fusion. Our data show that hPTH amplified BMP-2 and BMPR2 in bone tissues of non-diabetic rats, but not in diabetic rats. Our data further demonstrate that hPTH plays a role in regulating BMP-2 and BMPR2 via mTOR-PI3K signal pathway. We suggest specific signaling pathways by which hPTH regulates BMP-2 via mTOR-PI3K mechanism in bone formation following spinal fusion. Notably, our data indicate under diabetic conditions this signal pathway is impaired, thereby likely affecting bone formation after spinal fusion. The subsequent induction of BMP-2 and BMPR2 are likely a part of the protective effects aimed at attenuating pathological bone damage as a result of diabetes.

Abstract
A new type of tissue-engineered bone was constructed by seeding hVEGF165 gene-modified endothelial progenitor cells into the nanohydroxyapatite/collagen/poly(L-lactic acid) scaffolds. These were implanted into the segmental femoral defects of rats to explore the promotion of angiogenesis and osteogenesis. The bone marrow of Sprague Dawley rats was cultured and proliferated, and the endothelial progenitor cells were transfected with Ad5–hVEGF165–EGFP. The gene-modified endothelial progenitor cells were seeded into the nanohydroxyapatite/collagen/poly(L-lactic acid) scaffolds; the growth was observed by scanning electron microscope, and the proliferation was evaluated by methyl thiazolyl tetrazolium assay. In vivo, 80 Sprague Dawley rats were divided randomly into four groups; segmental femoral defects (5 mm) were made and allografted: group A with hVEGF165/endothelial progenitor cells–nanohydroxyapatite/collagen/poly(L-lactic acid), group B with mock endothelial progenitor cells–nanohydroxyapatite/collagen/poly(L-lactic acid), group C with endothelial progenitor cells–nanohydroxyapatite/collagen/poly(L-lactic acid), and group D with scaffolds only. Radiographic, histological, and microvessel density tests were performed to evaluate the angiogenic and osteogenic ability. Reverse transcription polymerase chain reaction and western blot results showed that the target gene was expressed by endothelial progenitor cells. The scanning electron microscope findings and methyl thiazolyl tetrazolium assay revealed that endothelial progenitor cells were attached and proliferated within the nanohydroxyapatite/collagen/poly(L-lactic acid) scaffolds. The average radiographic score and capillary density were the highest in group A, and those in groups B and C were higher than that of group D. The histology showed osteogenesis and scaffold degradation in group A, with less in groups B and C and little in group D. The hVEGF165 gene-modified endothelial progenitor cells, which promoted angiogenesis and osteogenesis in bone-defected areas and the hVEGF165/endothelial progenitor cells–nanohydroxyapatite/collagen/poly(L-lactic acid) composites, may have potential application in repair of segmental bone defects.

Abstract
OBJECTIVE The objective of this study was to summarize the clinical experiences in repairing abdominal incisional hernia with prosthetic materials. METHODS Eighty-three patients with ventral hernia were analyzed retrospectively. RESULTS Two patients developed pulmonary infection, one developed adhesive ileus, and five developed wound infection. All wounds healed completely during follow-up. Seventy-three (88%) patients were free of pain, and ten patients (12%) felt pain in the operated area within the last month; only one patient required pain-relieving drugs. Twenty-nine patients (35%) felt discomfort, such as stiffness. Four cases experienced postoperative recurrence. CONCLUSIONS Incisional herniorrhaphy with prosthetic materials is safe and effective but has a high discomfort rate. Open giant incisional hernia or recurrent incisional hernia should be performed by trained surgeons. Placing mesh in a suitable position and using a patch with minimal reaction and enough tensile strength may improve the prognosis. Further studies are necessary utilizing light polypropylene mesh.

Abstract
To investigate the clinical safety and effectiveness of acellular extracellular matrix (AEM) for inguinal hernia repair, 53 well-conducted and well-chosen sequential cases with inguinal hernia (56 inguinal hernias) were included in our multi-center study. All the inguinal hernias were repaired using conventional tension-free surgical procedures after being classified with Gilbert methods. No rejection was observed after operation. All the incisions healed well and no recurrence was found at the sixth month follow-up. At the seventh month after operation, one case of recurrence of right-side bilateral inguinal hernia (type IV) and another case of recurrence of left-side inguinal hernia (type V) were found. No other recurrence was observed at the 18th month follow-up. The AEM material has good histocompatibility and biomechanics characters and can be used for inguinal hernia repair. We observed no infection, chronic pain, funiculotesticular reaction, local nodular or feeling of discomfort after operation. But a further study of the usage of AEM in the repair of type IV and V inguinal hernias is still needed.
