BACKGROUND:The structure of tissue engineering carrier affects the bio-action of cells greatly.OBJECTIVE: To investigate the biological characteristics of bone marrow stem cells (MSCs) in different concentrations of alginate combined with de-antigen bone xenograft (DBX).DESIGN: Observational trial.SETTING: PLA Institute of Trauma and Orthopedics, the Fourth Military Medical University of Chinese PLA.MATERIALS: Alginate, calcium chloride, MSCs, bone xenograft.METHODS: Bovine cancellous bone was out into cubes, which were degreased, deproteinized and then lyophilized.Cubes in pore size within 300-500 μm were selected for use after ethylene oxide sterilization. The purified sodium alginate was dissolved in DMEM cell culture medium of concentrations as different as 0.5%, 2%, 8% and 16%; 1×1012 L-1 induced MSCs were blended with isopyknic alginate-DMEM and compounded with DBX at a status of 0.5 Mpa negative pressure for 5 minutes in order to make a cell suspension fully fill into the pores of the cancellous bone. Then alginate was crosslinked with 50 g/L calcium gluconic acid for 30 seconds. The complex was put into a CO2 incubator and cultured for 4 days. The gel compound and cell growth in the pores of the complex were grossly observed with an inverted microscope. Status of cell growth in the complex with different concentrations of alginate was observed with scanning electron microscopeMAIN OUTCOME MEASURES: Compound status of alginate and bone xenograft, cell growth status and matrix secretion in compound carries.RESULTS: When the concentration of alginate was 0.25% or 1%, alginate was equally combined in DBX, while that of 4% and 8% only combined on the surface of cancellous bone. After in vitro cultured for 4 days, alginate of 0.25% were broken off from DBX surface. But alginate of 1% was equally combined with DBX pores with cells secreting well in alginate. Development of cells in alginate of 4% was restricted and no cells were seen in alginate of 8%.CONCLUSION: Alginate of 1% is suitable for constructing the carrier of bone tissue engineering with bone xenograft.

Objective:To investigate the diagnostic value of the promoter methylation of plasma RNF180 gene and its protein ex-pression for the detection of gastric cancer. Methods:Methylation-specific polymerase-chain reaction (MSP) and enzyme-linked immu-no-sorbent assay (ELISA) were performed to detect DNA methylation and protein expression of the RNF180 gene, respectively. The correlations of DNA methylation and protein expression of the RNF180 gene with the clinico-pathological parameters of gastric carcino-ma were then separately analyzed. Results:MSP showed that the methylation rates of the RNF180 gene were 62.75%and 21.88%in the plasma of patients with gastric carcinoma and healthy volunteers, respectively;this result indicated that the two groups significantly differed (P<0.01). The methylation of the RNF180 gene was associated with tumor size, clinical stage, tumor differentiation, lymph node metastasis, and distant metastasis (P<0.05). ELISA results showed that the protein expression of the RNF180 gene [(23.22 ± 1.36)μg/mL] was significantly lower (P<0.01) in the plasma of patients with gastric carcinoma than in the plasma of healthy volunteers [(34.25 ± 2.44)μg/mL]. However, the protein expression of the RNF180 gene was not associated with clinicopathological parameters (P>0.05). Conclusion:The RNF180 gene is expressed at a hypermethylation rate, and the corresponding protein expression level is de-creased in the plasma of individuals with gastric carcinoma. Therefore, RNF180 gene methylation in plasma could be applied to detect microinvasion for the clinical diagnosis of gastric cancer.

BACKGROUND: Alginic acid has a relatively mild gel condition and good biocompatibility, and it has been widely used in bio-tissue engineering.OBJECTIVE: To construct bone tissue engineering scaffolds using alginate gel composite bone xenograft approach, and to observe the cell biological properties and in vivo osteogenic potential in scaffolds.METHODS: The bone marrow was harvested from two 2-week-old New Zealand rabbits, 1 ×10~(-8)mol/L recombinant human bone morphogenetic protein-2 was used to induce bone marrow mesenchymal stem cells. The induced bone marrow mesenchymal stem cells at the second generation were incubated into 1% sodium alginate gel, after cultured for 4 days, the cell morphology in gel was observed by hematoxylin-eosin staining. Bone marrow mesenchymal stem cells at the second generation were divided into simple DMEM gel group and DMEM containing 1% sodium alginate gel group, followed by a culture of 7 days. Then bone morphogenic protein-2 immunohistochemical staining was performed. A total of 24 nude mice were randomly divided into two groups, both sides of the thigh muscle pockets were implanted with bone marrow-derived mesenchymal stem cells/alginate gel/bovine cancellous bone complex as an experimental group, with bone marrow-derived mesenchymal stem cells/bovine cancellous bone as a control group. At 2 and 4 weeks post-operation, the osteogenesis in the composite was observed by histological examination, the percentage area of new bone or cartilage was determined using image analysis system.RESULTS AND CONCLUSION: The bone marrow-derived mesenchymal stern cells in the sodium alginate gel exhibited a well-stacked morphology, they suspended in a gel, showing cell division and mitosis phase. In the simple DMEM gel group and DMEM gel containing 1% sodium alginate group, the immunohistochemical results showed that, cell division and proliferation were normal, with prominence at a variety of forms, large nucleus, and clear nucleolus. The bone morphogenetic protein-2 expression had no significant difference between the simple DMEM gel group and DMEM gel containing 1% sodium alginate group (P>0.05).Scanning electron microscopy revealed that, the alginate gel evenly composited in bovine cancellous bone micropores, cell grew at different planes. Animal experiments showed that there were significant differences regarding the percentage of new bone or cartilage area between the experimental group and control group at 2 and 4 weeks postoperation (P< 0.05). It is indicated that constructing bone tissue engineering scaffolds by using alginate gel/bovine cancellous bone, complies with the ultra-structural principle of tissue engineering scaffolds, can maximize the cell loads, achieve good bio-performance, without adverse affects on the proliferation, osteogenic phenotype and related biological properties of bone marrow-derived mesenchymal stem calls, the in vivo osteogenic efficiency was high.

Objective? To explore the effects of enhanced recovery nursing on early postoperative vein thromboembolism (VTE) risk after pancreaticoduodenectomy (PD). Methods? Using convenience sampling method, the 45 cases of PD patients with traditional nursing methods from September 2016 to March 2017 were assigned as the control group, and the 66 cases of PD patients with enhanced recovery nursing from March 2017 to June 2018 were assigned as intervention group. The plasma D-dimer level before operation, immediately after operation, and in different postoperative days (POD): POD1, POD2, POD3 and POD7 were collected. The D-dimer level and the incidence rates of symptomatic VTE were compared between two groups. Results? The D-dimer values of the intervention group immediately after surgery, POD1, POD2, POD3 and POD7 were (2.74±2.31), (3.31±2.03), (3.98±3.10), (4.30±2.89) and (7.46±3.90) mg/L·FEU. The D-dimer of the control group at each postoperative time point were (2.88±1.92), (3.77±2.72), (4.37±2.70), (4.08±1.81) and (6.85±4.07) mg/L·FEU. The overall D-dimer value of the two groups showed an upward trend after operation,but there was no significant difference between two groups (P>0.05). Repeated measures analysis of variance showed that there were no differences in between-group effect (F=0.03, P=0.87) or interaction effect (F=1.01,P=0.38) of D-Dimer, while the difference in intra-group effect was statistically significant (F=108.28, P< 0.05). There was no statistical significance in the difference of the incidence rates of symptomatic VTE between two groups (χ2=0.87, P> 0.05). Conclusions? The early postoperative VTE risk after PD gradually increased, and the enhanced recovery nursing show no significantly advantage in VTE risk reduction after PD compared to traditional methods.

Hepatosplenic candidiasis (HSC) is a rare type of candidiasis that can occur in patients with hematologic malignancies, hematopoietic stem cell transplantation. At present, there is still a lack of studies on HSC in patients with hematologic disorders. Based on The Chinese Guidelines for the Diagnosis and Treatment of Invasive Fungal Disease in Patients with Hematological Disorders and Cancers (the 6th revision), We retrospectively analyzed the clinical characteristics and prognosis of patients with HSC treated in Peking University Institute of Hematology from 2008 to 2022. Finally, eighteen patients were included, with 1 (5.6%) proven, 2 (11.1%) probable, and 15 (83.3%) possible HSC. Among them, 3 (16.7%) patients occurred after haploid hematopoietic stem cell transplantation and 15 (83.3%) patients occurred after chemotherapy. 6 (33.3%) patients had positive blood cultures, including 4 cases of Candida tropicalis and 2 cases of Candida albicans. At 4 weeks of antifungal therapy, 10 (58.8%) patients achieved partial response (PR), At 8 weeks, 1 (6.3%) patients achieved complete response and 10 (62.5%) patients achieved PR. At 6 months after diagnosis, 3 (16.7%) patients died of hematopoietic recurrence, and none of them died of HSC. As a rare fungal infection disease, HSC has a low positive rate of microbiological and histological examinations, a persistent treat cycle, and has difficulty in remission, reminding us of the need for vigilance in patients with hematopoietic disorders and persistent fever.

OBJECTIVETo establish rabbit VX2 colorectal cancer(CRC) model and to compare CT images with gross pathology in order to offer help for TNM staging in patients with CRC.
METHODSVX2 tumor pieces were implanted into colonic wall in 9 New Zealand white rabbits and rectal wall in 2 New Zealand white rabbits. Four weeks after inoculation, Ultravist(370 mg/ml) was injected through ear marginal vein with high pressure injector for stage 3 scanning of chest, abdomen and pelvis, and enhanced CT (collimation 0.5 mm mm × 320, pitch factor 0.828, bulb rotation speed 0.5 s/cycle, 120 kV, automatic ma, range 80 to 100 mAs) was performed to determine the presence of CRC or metastasis once a week for 4-6 weeks. Once inoculated CRC or metastases occurred or 6 weeks after implantation, the rabbits were sacrificed regardless of the presence or absence of CRC or metastasis on the CT images. One rabbit was used for gross anatomy observation. Others were placed in wood boxes with -80centi-degree for 24 hours, then samples of 3 mm thickness were cut using a motorized saw to make macropathology. Each cutting surface of the specimens was photographed in serial number. If certain or suspected lesions were found on the slices, such part was labeled and then placed in 10% phosphate-buffered formaldehyde numbered box for subsequent pathological examination. CT image postprocessing was performed referring to the gross slice specimens and all findings were compared with the pathological reports.
RESULTSAmong 11 rabbits, tumor was successfully established in 8 rabbits. Pathology showed that single lung metastasis (7 to 10 mm) was found in 2 rabbits and liver metastasis (9 mm) in 1 rabbit. Number of lymph node located around the inoculated tumor was 22 and that around mesenteric vessels was 13 with diameter of 2 to 16 mm. Among these 35 lymph nodes from 8 successful rabbits, 9 nodes were positive, including 7 around inoculated tumor and 2 around mesenteric vessels. CT identified above 8 primary inoculated tumors, 2 lung metastatic lesions and 1 liver metastatic lesion, with detection rate of 100%. For the detection of lymph node in CT, 27 nodes were identified in the pericolorectal region (17 nodes) and perimesenteric vessels (10 nodes), in which 6 were positive metastasis (ring-shaped enrichment and central low density necrosis), resulting in a detection rate of 77.1%(27/35 nodes), and positive detection rate of 66.7% (6/9 nodes), respectively.
CONCLUSIONLiving rabbit CT-gross pathological slice(3 mm-cut) of VX2 CRC model can be applied in image evaluation of small metastatic lesion.
