BACKGROUND/OBJECTIVES: In this study, potential anti-inflammatory effect of enzymatic hydrolysates from Styela clava flesh tissue was assessed via nitric oxide (NO) production in lipopolysaccahride (LPS) induced RAW 264.7 macrophages and in vivo zebrafish model. MATERIALS/METHODS: We investigated the ability of enzymatic hydrolysates from Styela clava flesh tissue to inhibit LPS-induced expression of pro-inflammatory mediators in RAW 264.7 macrophages, and the molecular mechanism through which this inhibition occurred. In addition, we evaluated anti-inflammatory effect of enzymatic hydrolysates against a LPS-exposed in in vivo zebrafish model. RESULTS: Among the enzymatic hydrolysates, Protamex-proteolytic hydrolysate exhibited the highest NO inhibitory effect and was fractionated into three ranges of molecular weight by using ultrafiltration (UF) membranes (MWCO 5 kDa and 10 kDa). The above 10 kDa fraction down-regulated LPS-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), thereby reducing production of NO and prostaglandin E2 (PGE2) in LPS-activated RAW 264.7 macrophages. The above 10 kDa fraction suppressed LPS-induced production of pro-inflammatory cytokines, including interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha. In addition, the above 10 kDa fraction inhibited LPS-induced phosphorylation of extracellular signal-regulated kinases (ERKs), c-Jun N-terminal kinase (JNK), and p38. Furthermore, NO production in live zebrafish induced by LPS was reduced by addition of the above 10 kDa fraction from S. clava enzymatic hydrolysate. CONCLUSION: The results of this study suggested that hydrolysates derived from S. clava flesh tissue would be new anti-inflammation materials in functional resources.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

Aim To discuss the influence of endosome/ lysosome transport proteins SNX10 on macrophage, providing new potential targets for the treatment of variety of related immune diseases . Methods The genotype of mice was identified by PCR. The role of SNX10 in phagocytosis of bacterial components and sterilization by macrophages were assessed. The levels of TNF-α、IL-12 / 23 p40 and IL-6 were measured by q-PCR and ELISA assay. Finally, the NF-κB signaling pathway was evaluated by Western blot and immuno-fluorescence staining. Results Ex vivo experiments showed that SNX10 knockout could enhance bactericid-al ability and inhibit the expression and production of TNF-α, IL-12 / 23 p40 and IL-6 of macrophages.These effects might attribute to the inhibition of NF-κB signaling pathway activation. Conclusion SNX10 knockout could enhance bactericidal ability and inhibit the inflammatory response of macrophages, and its mechanism may be achieved through the NF-κB signa-ling pathway.

Objective Analyse the change of left ventricular (LV) longitudinal and radial strain in patients with aortic regurgitation (AR) and discuss the relationship between the 2D strain parameter and the filling and ejection of LV. Methods Thirty healthy controls and 45 patients with AR (24 patients with moderate AR and 21 with severe AR) were enrolled in this study, LV systolic global peak radial strain(GRS), systolic global peak longitudinal strain(GLS) and systolic peak longitudinal strain(S), systolic peak longitudinal strain rate(SRs), early diastolic peak longitudinal strain rate(SRe) of every segment were measured or calculated using 2D-STE, early and late diastolic transmitral flow velocity (E, A) were recorded by pulsed Doppler echocardiography and early diastolic mitral annular velocity (Ea) were assessed by tissue Doppler imaging,the E/A and E/Ea ratio were calculated. Discuss the relationship of GLS and LV ejection fraction (LVEF), GLS and E/Ea using the Pearson correlation analysis. Results The GLS were (-20.09±1.47)%, (-18.68±1.52)%, (-12.56±3.25)%and the GRS were (46.71±7.65)%, (43.01±5.95)%, (28.52±6.13)% in control group, patients with moderate and severe AR (MAR group and SAR group) respectively. There were significant differences among the groups (F =82.08,47.69, both P < 0.01) as following:SAR group with control group and MAR group [ q=17.56,13.60 (GLS), q=13.44, 10.20 (GRS), all P<0.01),MAR group and control group [ q=3.42 (GLS), P<0.01]. The SRs of the apical segment were (-1.24±0.22)s-1, (-1.19±0.25)s-1, (-1.04±0.28)s-1 in control group,MAR group and SAR group respectively. There were significant differences among the groups (F=4.47, P < 0.05) as following:SAR group with control group and MAR group ( q=4.02,3.28, both P<0.01). The S, SRe of apical segment and the S,SRs,SRe of basal and midventricular in MAR group were all lower than the control group ( q=4.42, 5.01, 3.48, 3.24, 4.78, 4.12, 3.61, 6.72, all P < 0.01). Pearson correlation analysis revealed the GLS had a relationship with LVEF and E/Ea ( r=-0.73, 0.64, both P<0.01). Conclusion The reduced longitudinal strain and strain rate could detect LV dysfunction in patients with AR in early stage and the GLS had the ability to reflect the diastolic filling and systolic ejecting of the LV.

We expirenced multiple hepatocellular adenomatosis, which was proved by pathology, in 38 years old man who had no prior history of predisposing factors. The radiologic findings were different by the size of tumor mass and intratumoral hemorrhage. Ultrasound demonstrated inhomogeneous hyperechoic large mass in segment 5 of right lobe and hyperechoic or isoechoic multiple small nodules in right lobe. Computed tomography demonstrated low density mass without contrast enhacement. Central high density is noted in hemorrhagic portion. Magnetic resonance T1-weighted image demonstrated high signal intensity in mass and hemorrhagic portion. T2-weighted image demonstrated slightly high signal intensity in mass portion, high signal intensity in hemorrhagic portionand double-layered peripheral rim. Gradient echo image well demonstrated inhomogenesity of mass.

OBJECTIVES: Health is closely related to an individual's assessment of their quality of life and their subjective level of happiness. The aim of this study was to investigate the association between happiness index and self-rated health by utilizing a community health survey in Korea. METHODS: The study participants were 17,937 people living in Gyeongsangnam-do, Korea, who completed a community health survey in 2014. The non-subjective variables included in the statistical analysis were sex, age, region, education, income, and economic activity. The subjective awareness variables included self-rated health, self-rated oral health, chewing difficulty, pronunciation difficulty, and happiness index. Statistical analysis of the data was done using the SPSS 21.0 program. RESULTS: Evaluation of the subjective awareness levels revealed that the respondents that were better educated, whose income levels were higher, and those who engaged in an economic activity found themselves to be in better physical health and oral health. In contrast, the respondents that were female, older, and with residence in the counties reported a higher incidence of chewing difficulty. There was a positive correlation between happiness index and subjective awareness level, and a negative correlation between chewing difficulty and pronunciation difficulty. Happiness index was influenced the most by subjective health levels, followed by income, age, pronunciation difficulty, subjective oral health, chewing difficulty, academic credential, region, and sex. CONCLUSIONS: Therefore, in order to improve the happiness index of community residents, regular health checkups and systematic oral health education should be prepared in order to improve awareness of subjective health and reduce discomfort in the oral cavity, and efforts should be made to reduce the gap between regions.
