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 elucidate the roles of TANK-binding kinase-1(TBKl)in hepatitis B virus (HBV)infection induced interferon antiviral immunity.Methods Peripheral blood monocytes were separated by CD14 magnetic microbeads from healthy volunteers(HV)and chronic hepatitis B(CHB)patients.Purified mDCs were induced and proliferated in the culture medium with human granulocyte-macrophage concentration of 25 mg/L were stimulated.The mRNA expressions of TBK1,interferon regulatory factor (IRF)3 and interferon(IFN)-βwere quantified by real time polymerase chain reaction(PCR).The levels of IFN-β in supernatants were determined by enzyme-linked immunosorbent assay(ELISA).Reslllts The mRNA levels of TBK1,IRF3 and IFN-β did not change significantly at 0,12,24 and 48 h after the significantly at 0, 12, 24 and 48 h in CHB group, whereas, it was significantly up-regulated at 12 h in HV group. Conclusions Our results suggest that there may be some disorders in host antiviral signal transduction pathways downstream the binding between ligands and receptors on mDC surface. The insufficient IFN-β expression after HBV infection may result in persistent chronic infection.

Objective To study the relationship between plasma neurodegenerative protein level and non-motor symptoms(NMS)in PD patients.Methods Eighty-four PD patients served as a PD group and 54age-matched persons undergoing physical examination served as a control group. The NMS of PD patients were assessed according to the HAMD scale.The plasma levels of tau,p-tau181,Aβ-42andα-syn were measured by ELISA and analyzed by Spearman correlation analysis and binary logistic regression analysis respectively.Results The FSS score and plasmaα-syn level were significantly higher while the plasma Aβ-42level was significantly lower in PD group than in control group(3.22±1.68 vs 1.89±1.16,P=0.000;320.00±64.91ng/L vs 277.78±52.75ng/L,P=0.000;267.61±77.75ng/L vs 321.80±49.41ng/L,P=0.001).No significant difference was detected in plasma tau and p-tau181levels between the two groups(P＞0.05).The plasmaα-syn level was positively related with the FSS score(r=0.237,P=0.030)and was an influencing factor of FSS(OR=1.019,95％CI:1.006-1.032,P=0.004).Conclusion Plasma neurodegenerative protein level is related with NMS and plasmaα-syn level is a peripheral biomarker for fatigue in PD patients.

Objective:To investigate the effects of heme oxygenase-1 (HO-1) on hepatic sinusoidal endothelial cells (LSECs) proliferation, migration, and hepatocyte proliferation.Methods:Eighteen male C57BL/6 mouse aged 6-8 weeks old were underwent partial hepatectomy. Cell proliferation and HO-1 expression in residual liver tissue were detected by immunofluorescence histochemistry at 0 d, 2 d and 4 d after operation. In vitro, LSECs were transfected with adenovirus carrying HO-1 gene (HO-1 group), and the cells were transfected with empty vector adenovirus and the non-transfected cells were used as control. In addition, LSECs from different transfection groups were co-cultured with hepatocyte without contact to evaluate the effect of HO-1 expression on promoting hepatocyte proliferation. Western Blotting and RT-PCR were used to detect the protein and mRNA expression of HO-1, inhibitor of DNA binding and or differentiation (Id1), hepatocyte growth factor (HGF) and Wnt2. Cell proliferation was detected by EdU. The ability of cell migration was detected by Transwell migration assay.Results:Compared with 0 d after hepatectomy, LSECs proliferation and HO-1 expression within LSECs were increased significantly at 4 d after surgery. EdU positive rate of LSECs in HO-1 group (27.20±4.80)% was higher than that in empty vector group (12.47±3.30)% and non-transfected group (15.97±2.50)%. The number of LSECs migration in HO-1 group (258.70±36.56) was higher than that in empty vector group (122.00±38.16) and non-transfected group (107.70±30.01). The protein and mRNA expression level of HO-1, Id1, HGF and Wnt2 in HO-1 group were higher than that in empty vector group and non-transfected group. EdU positive rate of hepatocytes that co-cultured with LSECs in HO-1 group (18.33±2.52) % was higher than that in empty vector group (11.33±1.53)% and non-transfected group (11.7±2.08)%. The differences were statistically significant (all P<0.05). Conclusion:Up-regulation of HO-1 promoted LSECs proliferation and migration of, as well as up-regulation of HO-1 in LSECs enhanced the capacity of LSECs to promote hepatocyte proliferation.

In order to improve the success rate of supraclavicular deep venous catheterization and reduce mechanical complications, we present an auxillary maneuver in regard to supraclavicular subclavian catheterization basing on the relatively fixed anatomy of subclavian vein and its adjacent surroundings, furthermore, we revised the standardized procedure of supraclavicular subclavian catheterization. The maneuver is summarized in the shape of verses (verses: thumb navigation is well designed according to anatomy. Needle penetrated into vein should be parallel to coronal plane. Fine needle in position should be immobilized. Is it difficult for parallel puncture? Pressure determination is required when needle is in place. It is critical to distinguish which vessel has been inserted. Guidewire is advanced smoothly. Check blood return after expansion of skin and catheterization.). For teaching convenience, verses are considered to be more concise and memorable, as well as applicable to clinical practice, in order to provide some help for clinical teaching.

Objective: To study the therapeutic value of endoscopic ultrasonography-guided hepaticogastrostomy(EUS-HG) for patients with high malignant biliary obstructive jaundice. Methods: A total of 56 patients with high malignant obstructive jaundice hospitalized at the Second Affiliated Hospital of Nanjing Medical University and the Second Affiliated Hospital of Xuzhou Medical University from January 2014 to December 2017 were included in the study.

Levels of aspartate aminotransferase were 259.37±30.64 U/L, 62.28±26.58 U/L in the EUS-HG group and 242.37±29.52 U/L, 60.28±29.57 U/L in the PTCD group, and there was no significant difference between the two groups (P>0. 05). CRP levels were 52.57±31.95 mg/L, 16.95±8.77 mg/L in the EUS-HG group and 53.42±35.79 mg/L, 25.13±14.77 mg/L in the PTCD group (P<0.05). (3)There was significant difference in remission rate of anorexia and abdominal distension between the two groups [80.0%(16/20) VS 52.8%(19/36), P<0.05]. There was no significant difference in symptom relief of jaundice, pruritus or abdominal pain between the two groups [90.0%(18 /20)VS 91.7%(33/36), P>0.05]. (4) The incidence of total complications in the EUS-HG group (20.0%, 4/20) was significantly lower than that in the PTCD group (47.2%, 17/36, P<0.05). (5)The cost of operation in the EUS-HG group (22 685.26±2 356.16 yuan) was slightly higher than that in the PTCD group (20 529.57±4 135.63 yuan, P>0.05). (6) The median unblock period of double pig tail plastic stents in EUS-HG group patients was 102 days. Conclusion EUS-HG is a safe and effective method for the treatment of high malignant biliary obstructive jaundice. It can be used as the first choice for treatment after failure of conventional ERCP.
