BACKGROUND: Currently, the materials used in clinical practice to repair cruciate ligament of knee joint contain auto-graft bone- mid 1/3 patella tendon-bone (B-T-B), auto-semitendinous muscle, gracilis muscle and allogenic tissue graft. All of them are limited to a certain degree in clinical application. Therefore, people hope to consistently develop artificial ligaments to take the place of auto- and allografts. OBJECTIVE: To investigate the feasibility to construct artificial biological ligament (ABL) by applying a novel biochemical technique using porcine tendon as the raw material. DESIGN: Research of new biological material. SETTING: Department of Orthopedics, Third Affiliated Hospital of Sun Yat-sen University. MATERIALS: Adult pigs of either gender were provided by the Animal Center of Sun Yat-sen University. Scanning electron microscope (SEM, S-520) was provided by Hitachi, Japan, and micro-controlled electron tension-testing device (Model LWK-10B) by Guangzhou Experimental Devices Factory. METHODS: The experiment was performed at the Animal Center of Sun Yat-sen University from January 2004 to June 2005. ABL was established by means of treating porcine tendon with epoxy cross-linking fixation, diversified antigen minimization process, mechanic enhancement modification and surface activating process. Under aseptic condition, a 6-month-old goat's bone marrow was abstracted, and then the bone marrow matrix stem cells were cultured in ABL stent for 3 weeks. Scanning electron microscope was used to observe structure and compatibility of artificial ligament, and mechanics test was used to analyze biomechanics characteristics of ABL. MAIN OUTCOME MEASURES: Structural features, cell compatibility and biomechanics characteristics of ABL.RESULTS: ① Structural features of ABL: The appearance of ABL was similar to that of the normal human ligament. Histological examination showed that the ABL was collagen fibers with no cells. Electron microscope examination revealed that the ABL was composed of hair-looking and fiber-like objects running uniformly in a certain direction and closely parallel-arranged. ② Cell compatibility: Three weeks after xenogenic marrow matrix cells were cultured on the surface of the ABL, it was noted that cells adhered and the matrix secreted by the cells precipitated around the cells. There were no cells found inside the ABL. ③ Mechanical strength of the ligament: The average diameter of ABL was 5 mm and the mechanical test at a speed of 100 mm/min showed that its averaged tensile limit was 927.19 N and the tension-resistant strength was 47.22 N/mm those were close to the corresponding parameters of the normal goat's ACL. The normal goat's ACL was 5 mm. The greatest tensile load was 807.50 N and the tension-resistant strength was 41.13 N/mm.CONCLUSION:As we used the unique biochemical technique and minimized the xenogenic protein immunogenicity of the porcine tendon, ABL has acceptable biomechanical properties and superior biocompatibility. As a substitute of the ligament in the reconstruction of the ACL, ABL has a promising prospect in clinical applications.

Objective To investigate the effect of continuous blood purification (CBP) on peripheral blood monocyte membrane CD14 (mCD14) expression and inflammatory response in patients with traumatic sepsis Methods A retrospective case control study was conducted on the clinical data of 50 patients with severe sepsis after trauma treated between January 2015 and December 2016. There were 34 males and 16 females, with an average age of 45.37 years (range, 16-73 years). Patients were divided into CBP group (25 cases) and non-CBP group (25 cases) according to whether they agreed to receive CBP treatment. The peripheral blood samples were collected at 0, 12, 24, 48, and 72 hours after treatment, and the mCD14 and leukocyte elastase (HLE) expressions were detected by flow cytometry and by ELISA, respectively. The peripheral blood mononuclear cells were isolated from the two groups 24 h after treatment and cultured in vitro. The variations of mCD14 expression in mononuclear cells were measured at 4, 8, 12, 24, 48, and 72 h after stimulation with lipopolysaccharide (LPS). The expression levels of tumor necrosis factor (TNF) -a, interleukin (IL) -6, and IL-10 in mononuclear cells were detected by ELISA. Results At 12, 24, 48, and 72 hours after treatment, the leukocyte elastase levels in the two groups were lower than those before treatment (P < 0.01), and the decrease in CBP group was significantly greater than that of non CBP group(P<0.01). At 12, 24, 48, and 72 hours after treatment, the mCD14 levels in both groups were up-regulated before treatment (P <0.01), and the increase in CBP group was significantly greater than that of non CBP group (P < 0.01). The mCD14 expressions before treatment, 4 h after treatment, and 8 h after treatment in CBP group were all higher than those in non CBP group at the same time points. At 4, 8, 12, 24, and 48 hours after the re-stimulation with LPS on the mononuclear cells in both groups, the levels of TNF-α and IL-6 in CBP group were significantly higher than those in non-CBP group (P <0.01), and there was no significant difference in IL-10 levels between the two groups (P >0.05). Conclusions CBP treatment can increase monocyte mCD14 expressions through eliminating inflammatory factors and pro-inflammatory mediators and reducing HLE directly or indirectly in patients with traumatic sepsis. When the body is stimulated again, its anti-inflammatory response ability is markedly stronger than that of patients who have not received CBP treatment.
