Abstract
Asians have a higher carrier rate of pulmonary arterial hypertension (PAH)-related genetic variants than Caucasians do. This study aimed to identify PAH-related genetic variants using whole exome sequencing (WES) in Asian idiopathic and heritable PAH cohorts. A WES library was constructed, and candidate variants were further validated by polymerase chain reaction and Sanger sequencing in the PAH cohort. In a total of 69 patients, the highest incidence of variants was found in the BMPR2, ATP13A3, and GDF2 genes. Regarding the BMPR2 gene variants, there were two nonsense variants (c.994C>T, p. Arg332*; c.1750C>T, p. Arg584*), one missense variant (c.1478C>T, p. Thr493Ile), and one novel in-frame deletion variant (c.877_888del, p. Leu293_Ser296del). Regarding the GDF2 variants, there was one likely pathogenic nonsense variant (c.259C>T, p. Gln87*) and two missense variants (c.1207G>A, p. Val403Ile; c.38T>C, p. Leu13Pro). The BMPR2 and GDF2 variant subgroups had worse hemodynamics. Moreover, the GDF2 variant patients were younger and had a significantly lower GDF2 value (135.6 ± 36.2 pg/mL, p = 0.002) in comparison to the value in the non-BMPR2/non-GDF2 mutant group (267.8 ± 185.8 pg/mL). The BMPR2 variant carriers had worse hemodynamics compared to the patients with the non-BMPR2/non-GDF2 mutant group. Moreover, there was a significantly lower GDF2 value in the GDF2 variant carriers compared to the control group. GDF2 may be a protective or corrected modifier in certain genetic backgrounds.

Abstract
Primary mediastinal large B-cell lymphoma (PMBCL) is an aggressive B-cell lymphoma originating from the thymus, which has different clinical and biological characteristics from diffuse large B-cell lymphoma, NOS. PMBCL tends to occur in young women, usually presenting as a large anterior mediastinal mass. Most patients are in stage Ⅰ-Ⅱ at the time of presentation. There is no standard prognostic scoring system for PMBCL. Immunochemotherapy is commonly used in the treatment of PMBCL, but the optimal first-line treatment has not been determined, and the status of radiotherapy is controversial. The value of PET-CT guided therapy needs to be further verified. Relapsed/refractory PMBCL has a poor prognosis, while novel therapies such as PD-1 inhibitors, brentuximab vedotin, and CAR-T can help improve survival in these patients.

Abstract
Excessive fructose intake presents the major risk factor for metabolic cardiovascular disease. Perivascular adipose tissue (PVAT) is a metabolic tissue and possesses a paracrine function in regulating aortic reactivity. However, whether and how PVAT alters vascular function under fructose overconsumption remains largely unknown. In this study, male Sprague-Dawley rats (8 weeks old) were fed a 60% high fructose diet (HFD) for 12 weeks. Fasting blood sugar, insulin, and triglycerides were significantly increased by HFD intake. Plasma adiponectin was significantly enhanced in the HFD group. The expression of uncoupling protein 1 (UCP1) and mitochondrial mass were reduced in the aortic PVAT of the HFD group. Concurrently, the expression of peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) and mitochondrial transcription factor A (TFAM) were suppressed. Furthermore, decreased fusion proteins (OPA1, MFN1, and MFN2) were accompanied by increased fission proteins (FIS1 and phospho-DRP1). Notably, the upregulated α-smooth muscle actin (α-SMA) and osteocalcin in the PVAT were concurrent with the impaired reactivity of aortic contraction and relaxation. Coenzyme Q10 (Q, 10 mg/100 mL, 4 weeks) effectively reversed the aforementioned events induced by HFD. Together, these results suggested that the dysregulation of mitochondrial dynamics mediated HFD-triggered PVAT whitening to impair aortic reactivity. Fortunately, coenzyme Q10 treatment reversed HFD-induced PVAT whitening and aortic reactivity.

Abstract
Adipogenesis has emerged as a new therapeutic target for regulating metabolism and achieving anti-inflammatory and anti-atherosclerotic effects via the release of adiponectin. However, at present, the effects and mechanism of action of dipeptidyl peptidase 4 (DPP4) stimulation on adiponectin production and adipogenesis have not been clarified. Here, we investigated the effects of DPP4 stimulation with monocyte chemoattractant protein-1 (MCP-1) on platelet-derived growth factor receptor alpha (PDGFRα) expression in adipose tissue and blood adiponectin levels. Stromal vascular fractions (SVFs) purified from human subcutaneous adipose tissue and inguinal adipose tissue of obese and diabetic (Leprdb/db) mice were treated with 50 ng of MCP-1 and plasma from control (Lepr+/+) mice supplemented with 10 ng or 50 ng of MCP-1. Treatment of SVFs from human subcutaneous adipose tissues with 50 ng of MCP-1 significantly increased AdipoQ, DPP4, peroxisome proliferator-activated receptor gamma (PPARγ), fatty-acid-binding protein (FABP4), and SERBF1 mRNA expression. MCP-1-supplemented plasma increased adiponectin, CCAAT-Enhancer-binding protein alpha (C/EBPα), DPP4, IL-33, and PDGFRα mRNA expression and adiponectin and DPP4 protein expression, while decreasing the expression of IL-10 mRNA in SVFs compared with the levels in the plasma treatment group. MCP-1-supplemented plasma was shown to increase PPARγ, PPARγ2, adiponectin, DPP4, and FABP4 and decrease IL-10 mRNA expression in PDGFRα cells from adipose tissue. Meanwhile, MCP-1-supplemented plasma increased MCP-1, PDGFRα, TNFα, adiponectin, and IL-1β and decreased IL-10 and FOXP3 mRNA expression in DPP4 cells. Moreover, the injection of MCP-1-supplemented plasma into adipose tissue increased the proportion of DPP4+ cells among PDGFRα+ cells from adipose tissue and plasma adiponectin levels of Leprdb/db mice compared with the levels in the plasma injection group. Our results demonstrate that DPP4+ cells are important adipose progenitor cells. Stimulation of DPP4 with MCP-1 increases adipogenesis-related gene expression and the population of DPP4+ cells among PDGFRα+ cells in SVFs and blood adiponectin levels. DPP4 stimulation could be a novel therapy to increase local adipogenesis and systemic adiponectin levels.

Abstract
BACKGROUND Current guideline-recommended multiparameters used to assess the risk levels of pulmonary arterial hypertension (PAH) are invasive hemodynamic measurements or effort-dependent exercise tests. Serum natriuretic peptide is only one kind of effort-free biomarker that has been adopted for risk assessment. This study aimed to investigate the application of homocysteine as a non-invasive and effort-free measurement for the risk assessment of patients with PAH. METHODS Samples of 50 patients diagnosed with PAH via right heart catheterization were obtained, and the patients were divided into low-, intermediate- and high-risk groups for further analysis. Additionally, serum N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) and homocysteine levels of monocrotaline (MCT)-induced PAH rats were analyzed at each week with progressed severity of PAH, and they were sacrificed on day 28 with pathology being assessed. RESULTS Hyperhomocysteinemia was an independent predictor (odds ratio [OR]: 1.256; 95% confidence interval [CI]: 1.002-1.574) and showed a linear correlation with NT-proBNP. Hyperhomocysteinemia could discriminate between low/intermediate and high-risk levels in PAH with a cut-off value in 12 μmol/L. Moreover, the elevated homocysteine levels by weeks in MCT rats also demonstrated the association between homocysteine and the severity of PAH. CONCLUSIONS Homocysteine can be a non-invasive and effort-free risk assessment for patients with pulmonary hypertension. Homocysteine level had a linear correlation with NT-proBNP level, and patients with hyperhomocysteinemia had a higher risk level, higher NT-proBNP level, and decreased lower diffusing capacity for carbon monoxide. The correlation between homocysteine level and PAH severity was also demonstrated in MCT rats.

Abstract
OBJECTIVE Fasciocutaneous free flap based on the peroneal artery (boneless version) is an option in our practice for head and neck reconstruction. However, the associated donor-site morbidity has rarely been discussed. Thus, this study investigated the long-term patient-reported donor-site morbidity associated with peroneal flaps. METHODS In this single-center, retrospective, observational study, 39 patients who underwent a free peroneal flap were enrolled. We evaluated donor-site morbidity with a modified questionnaire from Enneking et al. and Bodde et al. RESULTS Patient-reported daily life limitation was relatively low (5/39; 12.9%). Donor-site morbidities, namely pain (4/39; 10.3%), sensory disturbance (9/39; 23.1%), and walking limitation (9/39; 23.1%) were reported; most were rated minimal in severity. Among patients with walking limitation, muscle weakness (3/39; 7.7%), ankle instability (6/39; 15.4%), and gait alternation (6/39; 15.4%) were reported. Six patients developed claw toe. CONCLUSION Balancing successful reconstruction and donor-site morbidity is challenging. This long-term patient-reported survey revealed that harvesting peroneal flaps resulted in minimal or minor donor-site morbidity with no obvious impacts on the patients' daily quality of life. Although free radial forearm flaps and anterolateral thigh flaps are standard, free peroneal flaps have been proven reliable, with acceptable donor-site morbidity.

Abstract
Twenty-four male patients who underwent left ventricular assist device (LVAD) implantation due to advanced heart failure in Union Hospital, Fujian Medical University from June 2019 to June 2022 were retrospectively included. The age of patients was 32-61 (48.4±8.4) years. Everheat-Ⅰ, HeartCon and Corheart 6 left ventricular assist systems were used in 10, 6 and 8 cases, respectively. All patients were discharged successfully without mechanical failure, thrombosis or secondary thoracotomy for hemostasis. Early postoperative hemodynamics were significantly improved, left ventricular systolic diameter was reduced, left ventricular ejection fraction was gradually improved, and no hemolysis occurred. The patients were followed up for 3 to 39 (17.9±8.6) months, the cardiac function was restored to grade Ⅰ to Ⅱ, and the 6-minute walking test distance increased significantly. Therefore, satisfactory early results can be achieved with left ventricular assist device implantation for the treatment of heart failure.

The effects and mechanism of platelet-rich plasma treatment on fat graft survival and adipogenesis have not been clarified. Here, we aimed to study the effects of monocyte chemoattractant protein-1 (MCP-1)-supplemented plasma on adipogenesis-related gene expression and adiponectin levels. Stromal vascular fractions (SVFs) purified from the inguinal adipose tissue of obese and diabetic (Leprdb/db) mice were treated with plasma from control (Lepr+/+) mice supplemented with 10 or 50 ng of MCP-1. The expression of adiponectin and interleukin-33 (IL-33) mRNA in adipose tissue was increased in Leprdb/db mice, whereas control (Lepr+/+) plasma reduced expression of IL-33 mRNA as well as peroxisome proliferator-activated receptor gamma (PPARγ), pJNK, and pNF-κB protein, and increased the expression of IL-10 mRNA in SVFs of Leprdb/db mice. MCP-1-supplemented control plasma increased the expression of adiponectin, CCAAT-enhancer-binding protein α (C/EBPα), dipeptidyl peptidase 4 (DPP4), IL-33, and PDGFα mRNA and the expression of adiponectin protein as well as PPARγ of SVFs and the expression of PPARγ mRNA in adipose tissue macrophages (ATMs). Injection of MCP-1-supplemented plasma into adipose tissue of Leprdb/db mice increased the expression of IL-33 and Col3a1 mRNA in SVFs and IL-33, FABP4, PDGFα, PPARγ and PPARγ2 of ATMs, protein expression of adiponectin and PPARγ of SVFs, and plasma adiponectin levels, as well as DPP4 activity. In conclusion, our results demonstrate that control plasma decreases adipogenesis and increases IL-10, and decreases IL-33, pJNK, and pNF-κB in adipose tissue. MCP-1-supplemented plasma enhances adipogenesis-related gene expression in SVFs and adiponectin levels, which may be mediated through an increase of IL-33 and PPARγ. Thus, our findings suggest that MCP-1-supplemented plasma represents a novel therapy to stimulate local adipogenesis and systemic adiponectin levels.

Abstract
BACKGROUND Adipose tissue inflammation is considered as one of the major mechanisms underlying the pathogenesis of insulin resistance and complications in diabetes. Here, we aimed to study the effects of adipose-derived stromal cells on diabetes-induced insulin resistance and M1 cytokine expression. METHODS Stromal vascular fractions (SVFs) purified from the inguinal adipose tissue of diabetic mice were treated with plasma from either nondiabetic (Lepr+/+) or diabetic (Leprdb/db) mice and injected into the inguinal white adipose tissue of Leprdb/db mice. RESULTS We found that diabetic plasma treatment induced, whereas nondiabetic plasma suppressed TNF-α, IL-1β, and dipeptidyl peptidase 4 (DPP4) mRNA expression in SVFs in vitro. Importantly, the injection of nondiabetic plasma-treated SVFs significantly decreased TNF-α, IL-6, IL-1β, CCL2, and IL-33 and induced IL-10 mRNA expression in adipose tissue of Leprdb/db mice in vivo. Furthermore, we observed that nondiabetic plasma-treated SVFs increased mRNA expression of Foxp3 in adipose tissue macrophages and Foxp3 in adipose CD4+ T cells, decreased CD11b+CD11c+ cells in adipose tissue, and suppressed mRNA expression of ICAM-1, FCM3, IL-6, IL-1β, iNOS, TNF-α, and DPP4 as well as protein expression of DPP4 and phosphorylated JNK and NF-κB in the liver of Leprdb/db mice. Moreover, we found that nondiabetic plasma-treated SVFs increased Akt activation following insulin administration and attenuated glucose intolerance in Leprdb/db mice. CONCLUSIONS Our results demonstrate that nondiabetic plasma inhibits M1 but increases M2 cytokine expression in adipose tissue of diabetic mice. Most importantly, our findings reveal that nondiabetic plasma-treated SVFs are capable of mitigating diabetes-induced plasma DPP4 activity, liver inflammation, and insulin resistance and that may be mediated through suppressing M1 cytokines but increasing IL-10 and Tregs in adipose tissue. Altogether, our findings suggest that adipose stromal cell-based therapy could potentially be developed as an efficient therapeutic strategy for the treatment of diabetes.

Abstract
BACKGROUND Necrotizing fasciitis (NF) is a life-threatening disease with a fulminant presentation. Although early diagnosis can be aided by combining physical examination, the Laboratory Risk Indicator for Necrotizing Fasciitis score, and computed tomography, a mortality rate of 30% is still reported. In the modern times, an economical and efficient biomarker for predicting mortality in NF patients is still lacking. Platelet count is typically measured in routine blood tests and aids in predicting disease severity. We aimed to clarify the role of platelet count as a predictive factor for aspects of prognosis, such as mortality and surgical outcomes, in patients with NF. METHODS We identified 285 patients with NF between 2018 and 2020 in a single medical center in southern Taiwan. Medical records were collected for the evaluation of patients with thrombocytopenia. Univariate and multivariate analyses were performed for different outcomes. RESULTS We included 115 patients with confirmed diagnoses of NF. Twelve patients died with a mortality rate of 10.4%. Patients with thrombocytopenia exhibited a higher mortality rate (20.9% vs 4.2%, P = 0.006), more shock episodes (51.2% vs 11.1%, P < 0.001), higher intensive care unit admission rate (46.5% vs 13.9%, P < 0.001), and longer hospital length of stay (37.49 ± 24.12 days vs 28.82 ± 14.63 days, P = 0.037) than those without thrombocytopenia. All patients infected with Vibrio species exhibited thrombocytopenia. In multivariate analysis, independent risk factors for mortality were thrombocytopenia (odds ratio, 4.57; 95% confidence interval, 1.08-19.25) and single gram-negative bacterial culture from the wound (odds ratio 6.88; 95% confidence interval, 1.58-29.96). CONCLUSIONS In patients with NF and subsequent thrombocytopenia, a higher mortality rate, greater numbers of shock episodes, higher demand for intensive care unit, and longer hospital length of stay were observed than in those without thrombocytopenia. In patients with NF, platelet count is a valuable and economic indicator of prognosis. Once thrombocytopenia developed in patients with necrotizing fasciitis, aggressive antibiotic treatment and surgical management are required to improve the chances of recovery.

Abstract
Adipose tissue inflammation is a major cause of the pathogenesis of obesity and comorbidities. To study the involvement of M1/M2 cytokine expression of adipose tissue in the regulatory mechanisms of dipeptidyl peptidase 4 (DPP4) and insulin resistance in diabetes, stromal vascular fractions (SVFs) were purified from inguinal adipose tissue of diabetic (Leprdb/db) and non-diabetic (Lepr+/+) mice followed by analysis of M1/M2 cytokine expression. SVFs of Leprdb/db mice exhibited increased TNF-α, IL-6, IL-1β, CCL2, and DPP4 mRNA expression but decreased IL-10 mRNA expression. Plasma from Leprdb/db mice induced TNF-α, IL-6, IL-1β, CCL2, and DPP4 mRNA expression and plasma from Lepr+/+ mice induced IL-10 mRNA expression in SVFs from Leprdb/db mice. Injection of Lepr+/+ plasma into the adipose tissue of Leprdb/db mice decreased mRNA expression of TNF-α, IL-6, IL-1β, CCL2, and DPP4 and protein expression of pJNK and DPP4 in SVFs, reduced mRNA expression of ICAM, FMO3, IL-1β, iNOS, TNF-α, IL-6, and DPP4 and protein expression of ICAM, FMO3, and DPP4 in liver, and suppressed mRNA expression of TNF-α, IL-6, IL-1β, and DPP4 in Kupffer cells. Plasma from Leprdb/db mice did not induce M1 cytokine expression in SVFs from Leprdb/db-Jnk1-/- mice. Altogether, we demonstrate that diabetes induces M1 but decreases M2 cytokine expression in adipose tissue. Diabetic plasma-induced M1 expression is potentially through pJNK signaling pathways. Non-diabetic plasma reverses M1/M2 cytokine expression, plasma CCL2 levels, DPP4 activity, and Kupffer cell activation in diabetes. Our results suggest M1/M2 cytokine expression in adipose tissue is critical in diabetes-induced DPP4 activity, liver inflammation, and insulin resistance.

Abstract
BACKGROUND Patients in intensive care units (ICUs) often received broad-spectrum antibiotic treatment and Acinetobacter baumannii (A.b.) and Pseudomonas aeruginosa (P.a.) were the most common pathogens causing ventilator-associated pneumonia (VAP). This study aimed to examine the effects and mechanism of mechanical ventilation (MV) on A.b.-induced lung injury and the involvement of alveolar macrophages (AMs). METHODS C57BL/6 wild-type (WT) and c-Jun N-terminal kinase knockout (JNK1-/-) mice received MV for 3 h at 2 days after nasal instillation of A.b., P.a. (1 × 106 colony-forming unit, CFU), or normal saline. RESULTS Intranasal instillation of 106 CFU A.b. in C57BL/6 mice induced a significant increase in total cells and protein levels in the bronchoalveolar lavage fluid (BALF) and neutrophil infiltration in the lungs. MV after A.b. instillation increases neutrophil infiltration, interleukin (IL)-6 and vascular cell adhesion molecule (VCAM) mRNA expression in the lungs and total cells, IL-6 levels, and nitrite levels in the BALF. The killing activity of AMs against A.b. was lower than against P.a. The diminished killing activity was parallel with decreased tumor necrosis factor-α production by AMs compared with A.b. Inducible nitric oxide synthase inhibitor, S-methylisothiourea, decreased the total cell number in BALF on mice receiving A.b. instillation and ventilation. Moreover, MV decreased the A.b. and P.a. killing activity of AMs. MV after A.b. instillation induced less total cells in the BALF and nitrite production in the serum of JNK1-/- mice than those of WT mice. CONCLUSION A.b. is potent in inducing neutrophil infiltration in the lungs and total protein in the BALF. MV enhances A.b.-induced lung injury through an increase in the expression of VCAM and IL-6 levels in the BALF and a decrease in the bacteria-killing activity of AMs. A lower inflammation level in JNK1-/- mice indicates that A.b.-induced VAP causes lung injury through JNK signaling pathway in the lungs.

Abstract
BACKGROUND Head and neck reconstruction is complicated and is made even more challenging by free flap failure. We identified risk factors associated with free flap failure in records extracted from a nationwide database of a 23 million populations. METHODS We used International Classification of Diseases, Ninth Version, codes 140 to 149 and 161 to identify patients in Taiwan's National Health Insurance Research Database with head and neck cancer between 2000 and 2013. Patient's age, sex, neoadjuvant treatment, comorbidities, and anticoagulation use were also retrieved. Free flap reconstruction twice, or free flap and pedicle flap reconstructions during the same hospitalization were recorded as free flap failure. Logistic regression was used to identify factors that increased risk of free flap failure. RESULTS A total of 21,548 patients with head and neck cancer were identified; 883 (4.1%) experienced free flap failure. Use of aspirin, clopidogrel, urokinase, prostaglandin (PGE1), low-molecular-weight heparin, and operation time were associated with free flap failure. However, some potential confounders could not be identified from the database. CONCLUSIONS Several statistically significant findings were prone to influence by potential confounders. The clinically applicable result was that longer operation time and preoperative chemotherapy could increase the likelihood of free flap failure. On the other hand, several factors were proved to be irrelevant to free flap failure.

Abstract
Objective: To investigate the role of Orai1-mediated store-operated calcium entry in the immune damage of CD4+ T cells in septic mice. Methods: Sepsis mouse model was established by cecal ligation and puncture(CLP). Balb/c mice of clean grade were sacrificed 1, 3, and 5 days after operation. Spleen samples were harvested at given intervals. Splenic CD4+ T cells were selected by immunomagnetic beads and the expression of Orai1 protein was detected by western blotting, the storage operated calcium entry (SOCE) was detected by flow cytometry, the apoptosis of CD4+ T cells was detected by flow cytometry, the proliferation of CD4+ T cells was detected by CCK-8, and the IFN-γ and IL-4 were detected by enzyme-linked immunosorbent assay (ELISA). Then the expression of Orai1 protein was regulated to further detect the SOCE and immune function of splenic CD4+ T cells in mice. The experiment was divided into 4 groups, sham group, CLP3 group, Orai1 down group (Orai1-down group) and Orai1 up regulation group (Orai1-up group). Results: The relative expression of Orai1 protein in splenic CD4+ T cells in sham group was 1.03±0.16. Compared with sham group, Orai1 protein levels in CLP Group were all significantly lower (F=19.64, P=0.000 5). The increased value of splenic CD4+ T cells fluorescence intensity in sham group was 494±41. Compared with sham group, the levels of SOCE in CLP Group were all lower (F=30.01, P=0.001). The ratio of early and late apoptosis of CD4+ T cells in sham group was 8.7%±1.5%. Compared with sham group, the early and late apoptosis rates of CLP Group were significantly higher (F=32.29, P=0.000 1). The OD of sham group was 0.81±0.10 at 450 nm. Compared with sham group, the proliferation ability of splenic CD4+ T cells in CLP Group were significantly decreased (F=7.26, P=0.001 8). Compared with sham group, the secretion of IFN-γ and IL-4 by CD4+ T cells and the ratio of IFN-γ/IL-4 in CLP Group were all significantly decreased (F=19.690, 6.183, 11.230, all P<0.05). Compared with CLP3 group, the increased value of fluorescence intensity of CD4+ T cells was significantly decreased, the early and late apoptosis ratio of CD4+ T cells was significantly increased, the OD450 nm value of CD4+ T cells was decreased, the multiplication capacity of splenic CD4+ T cells were decreased, the level of IFN-γ and IL-4 secreted by T cells were decreased, and the value of IFN-γ/IL-4 in orai1-down group was decreased (t=4.819, 7.952, 2.988, 28.760, 3.140, 7.670, all P<0.05). However, Orail-up group showed the opposite trend. Conclusion: Orai1-mediated store-operated calcium entry can alleviate the immune dysfunction of CD4+ T cells in septic mice.

Abstract
OBJECTIVES Antiresorptive agents for bone pain were widely used to treat patients with advanced osteoporosis, multiple myeloma, and bone metastatic cancer. In recent years, however, bisphosphonate-related osteonecrosis of the jaw (BRONJ) has been a rare but major complication of this therapy. Most patients with BRONJ undergo dental procedures during treatment with antiresorptive agents. However, BRONJ may also occur spontaneously. This study reports 13 BRONJ patient cases at Kaohsiung Veterans General Hospital, Taiwan, and their related treatments. We also compare patients with cancer with patients with osteoporosis in treatment outcomes. METHODS Thirteen symptomatic patients with BRONJ were reviewed between 1985 and 2018 at Kaohsiung Veterans General Hospital. We included patients at advanced stage who were hospitalized for infection control of osteonecrosis of the jaw and excluded asymptomatic patients at stage 0 and stage 1. Four multiple myeloma, 3 patients with bone metastatic breast cancer and 6 patients with advanced osteoporosis (average ages, 63.57 ± 14.54 years in cancer patients and 79.5 ± 9.31 years in osteoporosis patients; average drug durations, 25.86 ± 27.23 months in cancer patients and 58.33 ± 23.87 months in osteoporosis patients; average follow-up times, 22.71 ± 14.46 months in cancer patients and 28.08 ± 36.35 months in osteoporosis patients) were included. RESULTS Seven patients were defined as having stage 3 (53.8%) and 6 as having stage 2 (46.2%) medication-related osteonecrosis of the jaw, according to the American Association of Oral and Maxillofacial Surgeons classification. The complete response rate with totally healed mucosa was 61.5%. Four cancer patients received free fibular flap (FFF) reconstruction with a high complete response rate (100%). All of them had a relatively better performance status, and the average age was also younger than osteoporosis patients. CONCLUSION Free fibular flap with a high complete response rate may improve pain relief and infection control for patients with BRONJ. Younger age is seemed to be a great indicator for FFF, but poor self-care ability (Eastern Cooperative Oncology Group status >3) is not suitable for these surgical treatments.

Abstract
BACKGROUND Osteoradionecrosis (ORN) is one of the most severe complications of free fibula reconstruction after radiotherapy. The gold standard treatment of osteomyelitis involves extensive debridement, antibiotics, and sufficiently vascularized muscle flap coverage for better circulation. Therefore, we hypothesized that free fibula flap with muscle could decrease the risk of ORN. METHODS This study consisted of 85 patients who underwent reconstruction with free fibula flap in head and neck cancer by a single reconstructive surgeon at Kaohsiung Veterans General Hospital over a period of 19 years (1998-2016). Patients with postoperative adjuvant radiotherapy were included in the study and were grouped by either free fibula osteocutaneous flap or free fibula osteomyocutaneous flap (with flexor hallucis longus muscle), and the incidence of ORN was compared. RESULTS Of the 85 patients, 15 were reconstructed with osteocutaneous fibula flap and 70 were with osteomyocutaneous fibula flap. The rate of ORN or osteomyelitis was significantly lower in the muscle group (18.6%, n = 13/70 vs. 46.7%, n = 7/15, p = 0.020, Chi-square test). CONCLUSION Vascularized muscle transfer increases perfusion of surrounding tissues and the bone flap, thereby decreasing the incidence of osteomyelitis or osteonecrosis.

Abstract
Objective This study compared the catechin composition of different tea byproducts and investigated the effects of dietary supplementation with green tea byproducts on the accumulation of abdominal fat, the modulation of lipid metabolism, and the inflammatory response in red feather native chickens. Methods Bioactive compounds were detected, and in vitro anti-obesity capacity analyzed via 3T3-L1 preadipocytes. In animal experiments, 320 one-day-old red feather native chickens were divided into 4 treatment groups: control, basal diet supplemented with 0.5% Jinxuan byproduct (JBP), basal diet supplemented with 1% JBP, or basal diet supplemented with 5×106 colony-forming unit (CFU)/kg Bacillus amyloliquefaciens+5×106 CFU/kg Saccharomyces cerevisiae (BA+SC). Growth performance, serum characteristics, carcass characteristics, and the mRNA expression of selected genes were measured. Results This study compared several cultivars of tea, but Jinxuan showed the highest levels of the anti-obesity compound epigallocatechin gallate. 3T3-L1 preadipocytes treated with Jinxuan extract significantly reduced lipid accumulation. There were no significant differences in growth performance, serum characteristics, or carcass characteristics among the groups. However, in the 0.5% JBP group, mRNA expression of fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC) were significantly decreased. In the 1% JBP group, FAS, ACC and peroxisome proliferator-activated receptor γ levels were significantly decreased. Moreover, inflammation-related mRNA expression levels were decreased by the addition of JBP. Conclusion JBP contained abundant catechins and related bioactive compounds, which reduced lipid accumulation in 3T3-L1 preadipocytes, however there was no significant reduction in abdominal fat. This may be due to a lack of active anti-obesity compounds or because the major changes in fat metabolism were not in the abdomen. Nonetheless, lipogenesis-related and inflammation-related mRNA expression were reduced in the 1% JBP group. In addition, dietary supplementation with tea byproducts could reduce the massive amount of byproducts created during tea production and modulate lipid metabolism and the inflammatory response in chickens.

Abstract
With the growing attention on ecological environment problems and gradual realization of ecological environment value, environmental damage has jumped from administrative penalty to a new stage, judicial penalty, and environmental damage appraisal has provided a legal weapon to safeguard ecological security. As a new forensic category of China with high comprehensiveness and technical difficulty, environmental damage appraisal involves diversified and complex subjects, fields and appraisal objects, and is still in an early stage in terms of theory and practice. This study aims to provide an important reference for the improvement of the Chinese environmental damage appraisal system of environmental damage by summarizing advanced international experience in areas such as laws and regulations, working mechanism and technical system, and putting forward targeted countermeasures and suggestions based on the problems existing in the development and practice of environmental damage appraisal in China.

Abstract
Background The effect of paramedic crew size in the resuscitation of patients with out-of-hospital cardiac arrest (OHCA) remains inconclusive. We hypothesised that teams with a larger crew size have better resuscitation performance including chest compression fraction (CCF), advanced life support (ALS), and teamwork performance than those with a smaller crew size. Methods We conducted a randomized controlled study in a simulation setting. A total of 140 paramedics from New Taipei City were obtained by stratified sampling and were randomly allocated to 35 teams with crew sizes of 2, 3, 4, 5, and 6 (i.e. 7 teams in every paramedic crew size). A scenario involving an OHCA patient who experienced ventricular fibrillation and was attached to a cardiopulmonary resuscitation (CPR) machine was simulated. The primary outcome was the overall CCF; the secondary outcomes were the CCF in manual CPR periods, time from the first dose of epinephrine until the accomplishment of intubation, and teamwork performance. Tasks affecting the hands-off time during CPR were also analysed. Results In all 35 teams with crew sizes of 2, 3, 4, 5, and 6, the overall CCFs were 65.1%, 64.4%, 70.7%, 72.8%, and 71.5%, respectively (P = 0.148). Teams with a crew size of 5 (58.4%, 61.8%, 68.9%, 72.4%, and 68.7%, P<0.05) had higher CCF in manual CPR periods and better team dynamics. Time to the first dose of epinephrine was significantly shorter in teams with 4 paramedics, while time to completion of intubation was shortest in teams with 6 paramedics. Troubleshooting of M-CPR machine decreased the hands-off time during resuscitation (39 s), with teams comprising 2 paramedics having the longest hands-off time (63s). Conclusion Larger paramedic crew size (≧4 paramedics) did not significantly increase the overall CCF in OHCA resuscitation but showed higher CCF in manual CPR period before the setup of the CPR machine. A crew size of ≧4 paramedics can also shorten the time of ALS interventions, while teams with 5 paramedics will have the best teamwork performance. Paramedic teams with a smaller crew size should focus more on the quality of manual CPR, teamwork, and training how to troubleshoot a M-CPR machine.

Abstract
Maternal high-fructose diets (HFD) impair the learning and memory capacity of adult female offspring via histone deacetylase 4 (HDAC4). Hippocampal adult neurogenesis is important for supporting the function of existing neural circuits. In this study, we investigated the effects of maternal HFD on hippocampal neural stem cell (NSC) proliferation and neuronal differentiation in adult offspring. Increased nuclear HDAC4 enzyme activity was detected in the hippocampus of HFD female offspring. The Western blot analyses indicated that the expressions of sex-determining region Y box2 (SOX2) and the transcription factor Paired Box 6 (PAX6), which are critical for the progression of NSC proliferation and differentiation, were downregulated. Concurrently, the expression of Ki67 (a cellular marker for proliferation) and doublecortin (DCX), which are related to NSC division and neuronal differentiation, was suppressed. Intracerebroventricular infusion with class II HDAC inhibitor (Mc1568, 4 weeks) led to the upregulation of these proteins. Environmental stimulation reversed the expression of Ki67 and DCX and the counts of Ki67- and DCX-positive cells in the hippocampi of HFD offspring as a result of providing the enriched housing for 4 weeks. Together, these results demonstrate that the suppressive effects of maternal HFD on hippocampal NSC proliferation and neuronal differentiation are reversibly mediated through HDAC4 and can be effectively reversed by environmental stimulation. The advantageous effects of environmental enrichment were possibly mediated by HDAC4 suppression.

Abstract
Asian population is a low-risk group for basal cell carcinoma (BCC) and there is little data available in this setting. Sun-exposed BCC (SEBCC) may possess a different pathogenic mechanism from non-sun-exposed BCC (NSEBCC). To compare the histopathological profiles and outcomes between SEBCC and NSEBCC, and to assess the risk factors for tumor recurrences. Retrospective cohort study on 372 patients with pathologically diagnosed BCC from January 1, 1990 to August 31, 2017. Data were derived from a single medical center in Taiwan. SEBCC presented with higher Clark level and more high-risk factors for recurrence than NSEBCC. Nodular, micronodular, infiltrating/mixed infiltrating, basosquamous, and adenoid types were predominant in SEBCC, as superficial type in NSEBCC. Risk factors for recurrence included infiltrating/mixed-infiltrating subtypes and synchronous basosquamous cell carcinoma. No recurrence events were observed in NSEBCC. Our study showed an acceptable recurrence rate (4.2%) of the whole population after excision even under a smaller surgical margin width than suggested by current guidelines. SEBCC had a higher recurrence rate with a significantly different tumor characteristic from NSEBCC and a greater tumor depth than NSEBCC. A wider surgical margin in SEBCC than NSEBCC is suggested.

Abstract
Aryl-hydrocarbon receptor (Ahr) plays an important role in the regulation of intestinal homeostasis. Diabetes is characterized by vascular complications and intestinal dysfunction. We aimed at understanding the relationship between intestinal defense impairment and inflammation in diabetes and effects of Ahr ligands on diabetes-induced insulin resistance, endovascular inflammation, and intercellular adhesion molecule (ICAM) and flavin mono-oxygenase (FMO3) expression. Effects of Ahr ligands, such as tryptophan (Trp) and indole-3-carbinol (I3C) on intestinal barrier and inflammation of Ins2Akita mice were examined. Myeloid differentiation primary response 88 (MYD88) is the adaptor for inflammatory signaling pathways. Ins2Akita-MyD88-/- mice were used to study the role of MyD88. Ins2Akita mice demonstrated decreased Ahr and regenerating islet-derived 3-β (Reg3β) expression, and increased Klebsiella pneumoniae translocation. Ins2Akita mice demonstrated increased inducible nitric oxide synthase (iNOS) expression of intestine; ICAM, iNOS, interleukin 1 beta (IL-1β), and FMO3 expression of liver; and ICAM, iNOS, and FMO3 expression in aorta. Trp and I3C decreased diabetes-induced translocation and increased Ahr and Reg3β expression of intestine. Ahr ligands reduced diabetes-induced ICAM and FMO3 expression in liver and aorta; IL-6, tumor necrosis factor alpha (TNF-α), and iNOS expression in Kupffer cells; plasma IL-6 and TNF-α levels; dipeptidyl peptidase (DPP4) activity; and insulin insensitivity. Ins2Akita-MyD88-/- mice demonstrated decreased expression of p-NF-κB of liver and ICAM of aorta compared with Ins2Akita mice. Altogether, our data suggest that diabetes induces ICAM and FMO3 expression through the decrease in intestinal defense and MyD88. Ahr ligands reverse diabetes-induced intestinal defense impairment, insulin insensitivity, FMO3/ICAM expression, and systemic inflammation.

Abstract
Objective: To investigate the protective effect of Baicalin on apoptosis induced by lipopolysaccharide in H9C2 cardiomyocytes and its possible mechanism. Methods: In order to establish apoptosis model of H9C2 cardiomyocytes, H9C2 cardiomyocytes were cultured and divided into four groups: the control group; the baicalin group was treated with baicalin at the final concentration of 10μmol/L for 12 hours; the LPS group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours; The LPS+baicalin group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours within treated with baicalin at the final concentration of 10μmol/L for 12 hours. Collecting cell samples, CCK-8 (The Cell Counting Kit-8) was used to detect cell activity, and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) was used to detect the expression levels of apoptosis. Laser Scanning Confocal Microscopy was used to detect the expression levels of store-operated calcium entry in H9C2 cardiomyocytes. Western blot was used to detect the protein expression levels of STIM1, cleaved-caspase3, Bax and Bcl-2. Fluorogenic quantitative PCR was used to detect the mRNA expression level of STIM1. Results: Compared with the control group, LPS-induced H9C2 cardiomyocyte survival rate decreased (P<0.05), the expression level of apoptosis increased (P<0.05), the internal flow of calcium increased (P<0.05), the expression levels of cleaved-caspase3, Bax protein levels increased (P<0.05), Bcl-2 protein level decreased (P<0.05), the expression of STIM1 mRNA and protein level increased (P<0.05). Compared with LPS group, the survival rate of H9C2 cardiomyocytes in baicalin intervention group increased (P<0.05), the expression level of apoptosis decreased (P<0.05), the internal flow of calcium decreased (P<0.05), the expression levels of cleaved-caspase3, Bax protein decreased (P<0.05), and the level of Bcl-2 protein increased (P<0.05), the expression of STIM1 mRNA and protein level decreased (P<0.05). Conclusion: Baicalin may alleviate LPS-induced cardiomyocyte apoptosis by alleviating calcium overload, and improve cell survival.

Abstract
BACKGROUND Infection by antibiotic-resistant microorganisms is common in intensive care units and has become a global problem. Here, we determined the effect of aryl hydrocarbon receptor (AhR) stimulation on antibiotics-induced systemic defense impairment and its mechanisms. METHODS C57BL/6 wild-type (WT) mice received combined antibiotics with or without Ahr ligands (tryptophan and indole), or dead Lactobacillus plantarum supplementation. The defense mechanisms against Pseudomonas aeruginosa infection in the lung were examined. RESULTS Antibiotic treatments decreased the phagocytic activity, physiological activity, and the peroxynitrite production of alveolar macrophage (AMs). It also enhanced P. aeruginosa pneumonia-induced bacterial counts in the lung. Tryptophan and dead L. plantarum supplementation reversed antibiotic-induced intracellular adhesion molecule (ICAM) as well as IL-6 expression, and increased P. aeruginosa pneumonia-induced bacterial counts in the lung and increased phagocytic activity and peroxynitrite production of AMs. Moreover, these treatments reversed the antibiotics-induced reduction of Ahr expression, antibacterial proteins, reactive oxygen species (ROS) production, and NF-κB DNA binding activity of the intestinal mucosa and plasma IL-6 levels. P. aeruginosa counts increased and phagocytic activity of AMs and myeloperoxidase (MPO) activity decreased in intestinal IKKβ depleted mice. Antibiotics, antibiotic with tryptophan feeding, or antibiotic with dead L. plantarum feeding treatments did not change the phagocytic activity and peroxynitrite production of AMs, plasma IL-6 levels, and the expression of Ahr of intestine in intestinal IKKβ depleted mice. CONCLUSION Antibiotic treatment impairs lung immune defenses by decreasing Ahr expression in the intestine and peroyxnitrite production of the AMs. Ahr ligands reverses antibiotic-induced lung defense against bacterial infection through intestinal ROS production and NF-κB activation. The gut is critical in maintaining lung defense mechanism through the intestinal IKKβ pathways.

Abstract
BACKGROUND Oxidized regenerated cellulose (ORC; Surgicel®; Ethicon, Neuchâtel, Switzerland) is an absorbable hemostatic agent used for hemostasis in operation, although some surgeons use it to position free flap pedicles. The increasing risk of vessel compromise is a huge concern. However, no scientific data to date demonstrate the safety and benefit of using ORC in microvascular surgery. In the present study, we compared the outcome of microvascular head and neck reconstruction with and without pedicle placement using ORC. MATERIALS AND METHODS From January 2015 to December 2017, we reviewed patients undergoing microvascular surgery with free fibular osteocutaneous flap in our hospital. The patients were divided into the ORC group and non-ORC group and their baseline characteristics and outcomes were compared. RESULTS In total, there were 27 patients in the ORC group and 67 in the non-ORC group. The non-ORC group had significantly higher cigarette consumption (70.4% vs. 89.6%; p = .022). The outcome of the ORC group was better regarding arterial thrombosis (0% vs. 3%), flap failure (0% vs. 4.5%), hematoma (7.4% vs. 10.4%), and wound complications (25.9% vs. 44.8%). The ORC group had a worse result than the non-ORC group for vein thrombosis (7.4% vs. 4.5%) and duration of hospitalization (24.111 days vs. 23.627 days). However, none of above results was significant. CONCLUSIONS Though this study was underpowered to detect the differences, the results showed a trend toward better outcomes of flaps and wounds in the ORC group. It seems that using ORC in this field is safe and beneficial.

Abstract
Background: The incidence of non-tuberculous mycobacterial (NTM) infections of the skin, soft tissue, and musculoskeletal system (SSTI) has increased over the past two decades, however, relatively few studies have documented the reasons for the reported increase. Specifically, no standardized treatment protocols have been adopted, therefore, clinical prognosis of the patients with NTM SSTI has thus far remained uncertain. In our study, we sought to identify risk factors for treatment failure in southern Taiwan. Methods: Patients with NTM SSTI, who received treatment between 2012 and 2015 were included in this retrospective study; detailed medical records, images, tissue specimens for culture, and pathology reports were collected for further analysis. Risk factors for treatment failure were determined using multivariable logistic regression. Results: Forty-two patients (16 females, 26 males; aged 58 ± 14 years) with NTM SSTI were included in the study. Isolated mycobacterial species included Mycobacterium abscessus complex, Mycobacterium marinum, Mycobacterium kansasii, Mycobacterium avium-intracellulare complex (MAC), Mycobacterium fortuitum, Mycobacterium gordonae, Mycobacterium haemophilum, Mycobacterium peregrinum, and Mycobacterium chelonae. The incidence of NTM SSTI was 23.6 per 100,000 inpatients. The sites of infection included the hand/wrist areas, spine, feet, lower legs, femur, knees, shoulders, and elbows, in 15, 6, 5, 5, 4, 3, 2, and 1 patients, respectively. The time interval between culturing the specimens and diagnosis averaged 21.2 ± 11.4 days. The main risk factors for treatment failure included treatment delays exceeding two months and infection with Mycobacterium abscessus complex. Conclusions: Improved clinical outcome of NTM with STI may be achieved by identifying the causative NTM species, and by initializing appropriate pharmacotherapy and surgical intervention. Non-tuberculous mycobacterial infection should be included in the differential diagnosis of SSTI and it is recommended that patients with an increased risk of treatment failure should receive prolonged antibiotic treatment and prompt surgical intervention upon diagnosis or indication of NTM infections.

Abstract
Excessive maternal high-fructose diet (HFD) during pregnancy and lactation has been reported to cause metabolic disorders in the offspring. Whether the infant's brain metabolism is disturbed by maternal HFD is largely unknown. Brain energy metabolism is elevated dramatically during fetal and postnatal development, whereby maternal nutrition is a key factor that determines cellular metabolism. Astrocytes, a nonneuronal cell type in the brain, are considered to support the high-energy demands of neurons by supplying lactate. In this study, the effects of maternal HFD on astrocytic glucose metabolism were investigated using hippocampal primary cultures of female infants. We found that glycolytic capacity and mitochondrial respiration and electron transport chain were suppressed by maternal HFD. Mitochondrial DNA copy number and mitochondrial transcription factor A expression were suppressed by maternal HFD. Western blots and immunofluorescent images further indicated that the glucose transporter 1 was downregulated whereas the insulin receptor-α, phospho-insulin receptor substrate-1 (Y612) and the p85 subunit of phosphatidylinositide 3-kinase were upregulated in the HFD group. Pioglitazone, which is known to increase astrocytic glucose metabolism, effectively reversed the suppressed glycolysis, and lactate release was restored. Moreover, pioglitazone also normalized oxidative phosphorylation with an increase of cytosolic ATP. Together, these results suggest that maternal HFD impairs astrocytic energy metabolic pathways that were reversed by pioglitazone.

Abstract
Background Widespread use of antibiotics in the intensive care unit is a potential cause of the emergence of hospital-acquired pneumonia. This study determined whether Lactobacillus salivarius feeding could reverse antibiotic-induced lung defense impairment in a ventilator model. Methods C57BL/6 wild-type (WT) mice received mechanical ventilation for 3 h after intramuscular antibiotic treatment for 6 days. Treatment with dead Lactobacillus salivarius and fructo-oligosaccharides (FOS) feeding were used to stimulate antibacterial protein expression in the intestine. Reactive oxygen species (ROS) in the intestinal mucosa was detected using 2ʹ7ʹ-dichlorofluorescein diacetate. The peroxynitrite production of alveolar macrophages (AMs) was measured using dihydrorhodamine 123 oxidation assay. N-acetylcysteine (NAC), an ROS scavenger, was orally administered to mice receiving antibiotics with FOS feeding. Results Antibiotic treatment decreased Pseudomonas aeruginosa (PA) phagocytic activity and activity of AMs and protein expression of regenerating islet-derived protein 3β (Reg3β) as well as Toll-like receptor 4 (TLR4) in the intestinal mucosa in the ventilator model. Antibiotic treatment also decreased ROS production in the intestinal mucosa, peroxynitrite production of AMs, and RELMβ expression as well as NF-κB DNA binding activity of the intestinal mucosa in WT mice but not in MyD88−/− mice. Treatment with dead L. salivarius or FOS feeding increased ROS production, bacterial killing activity, and protein expression of Reg3β as well as TLR4 in the intestinal mucosa and reversed the inhibitory effects of antibiotics on PA phagocytic activity of AMs. Conclusion Taken together with the finding that ablation of FOS-induced intestinal ROS using NAC decreased peroxynitrite production as well as PA phagocytic activity of AMs and protein expression of CRP-ductin, IL-17, Reg3β, and RELMβ in the intestinal mucosa, we conclude that commensal microflora plays a key role in stimulating lung immunity. Intestinal ROS plays a role as a predictive indicator and modulator of pulmonary defense mechanisms. Antibiotic treatment reduces lung defense against PA infection through the decrease in intestinal Reg3β and TLR4 expression. Treatment with dead L. salivarius or FOS feeding reverses the antibiotic-induced lung defense impairment through the intestinal ROS/MyD88 pathways.

Abstract
Objective: To investigate pulmonary vascular remodeling in rat model of pulmonary hypertension in left heart disease (PH-LHD). Methods: A total of 66 male minor Sprague-Dawley (SD) rats were randomly divided into control group (n=6), sham operation group (n=6) and model group (n=54). The rats in the control group entered the experimental procedure immediately without any treatment, and the rats in the sham operation group entered the experimental procedure 64 days after sham operation, and the rats in model group entered the experimental procedure (6 rats each) on day 1, day 3, day 5, day 8, day 15, day 22, day 36, day 50 and day 64 respectively after supracoronary aortic banding successfully. The lung tissue was fixed and cut and made into pathological sections to observe the characteristics of pulmonary vascular remodeling. Results: Medial thickening was mainly observed in pulmonary arterioles with diameter <100 μm [(11.17±1.03)%]. Additionally, medial thickening was seen in pulmonary arterioles with diameter 50-100 μm and 20-50 μm from day 15 [(12.73±1.15)%] and day 50 [(14.53±1.53)%], respectively. Medial muscularize of pulmonary arterioles were mainly observed in arterioles with diameter 20-50 μm, and deteriorated with time. Reduced pulmonary arteriole lumen size were observed with diameter 20-50 μm since day 50 (P<0.05). Conclusion: Pulmonary arteries with diameter >100 μm have little effect on the reconstruction of pulmonary vessels in PH-LHD rat model. However, arterioles with diameter 20-50 μm and 50-100 μm are the most important vessels involved in the formation of pulmonary hypertension, especially 20-50 μm.

Abstract
Diabetes mellitus (DM) is characterized by increased fatality associated with the atherogenetic process. Circulating trimethylamine-N-oxide (TMAO) levels are closely associated with atherosclerosis. The flavin mono-oxygenase family (Fmo) members oxidize trimethylamine (TMA) to TMAO. The effect and the regulatory mechanism of intestinal microflora on diabetes-induced Fmo3 and intercellular adhesion molecule (ICAM) expression were examined in streptozotocin-induced diabetic mice (STZDM) and Akita mice (C57BL/6J-Ins2Akita). STZDM-JNK1-/- and Ins2Akita-JNK1-/- mice were produced and used to study the role of pJNK in the regulatory mechanisms. Diabetic mice exhibited decreased Lactobacilli growth and reactive oxygen species (ROS) production in the intestinal mucosa; increased levels of pJNK and iNOS proteins in the intestinal mucosa; increased levels of serum nitrate, IL-1β, and TNF-α expression in Kupffer cells; increased Fmo3 expression in the liver; and increased ICAM expression in the aorta. Reversal of diabetes-induced enteric dysbiosis by prebiotic (FOS) or probiotic (dead L. plantarum) treatment decreased diabetes-induced pJNK and iNOS expression in the intestine, Fmo3 expression in the liver, IL-1β expression in Kupffer cells, and ICAM expression in the aorta and liver. Ins2Akita-JNK1-/- and STZDM-JNK1-/- mice demonstrated decreased levels of serum NO, IL-1β expression in Kupffer cells, Fmo3 expression in the liver, and ICAM expression in the aorta. GF mice cohoused with DM mice demonstrated an increase in ICAM expression in the liver. In conclusion, diabetes induced the expression of both Fmo3 and ICAM expression and possible vascular impairment through enteric dysbiosis. Diabetes-induced Fmo3 and ICAM expression could be reversed by pJNK inhibition or by correcting enteric dysbiosis.

Abstract
BACKGROUND Urinary intestine fatty acid binding protein (U-IFABP) is a biomarker for gut injury. Previous studies showed that enterocyte damage in critically ill patients was common and appeared to be associated with poor prognosis. However, the impact of enterocyte damage on the outcome of critically ill patients with pneumonia has not yet been well investigated. The aim of the study is to evaluate the prognostic value of U-IFABP in critically ill patients with pneumonia. METHODS A prospective observational study was performed in the intensive care unit (ICU) from September 1, 2013 to April 30, 2014. Pneumonia patients were divided into survival and non-survival groups. U-IFABP was measured using enzyme linked immunosorbent assay for 7 consecutive days after admission to ICU and expressed as U-IFABP/urine creatinine ratio. The prognostic value was tested by Receiver Operator Characteristic (ROC) curves and Kaplan-Meier curves. RESULTS A total of 32 pneumonia patients with endotracheal intubation were enrolled. U-IFABP/Cr levels were significantly higher in non-survivors than in survivors at day 1 (p = 0.033), day 4 (p = 0.018), day 5 (p = 0.008), day 6 (p = 0.006) and day 7 (p = 0.008) after ICU admission. The areas under ROC curve in predicting mortality were 0.755 (D1), 0.781 (D4), 0.812 (D5), 0.823 (D6), and 0.812 (D7). Moreover, pneumonia patients with day 7 U-IFABP/Cr above the cutoff of 28.9 pg/100 µL had a significantly lower survival rate (p = 0.043). CONCLUSIONS Enterocyte injury was common in critically ill patients with pneumonia. The severity of enterocyte injury, as evidenced by the U-IFABP/Cr, was associated with the patient's mortality. U-IFABP/Cr may serve as a significant prognostic factor for patients with pneumonia admitted to ICU. Further studies with larger populations are needed to verify these issues.

Abstract
AIM The effect of the number and level of on-scene emergency medical technicians (EMTs) on the outcomes of patients with out-of-hospital cardiac arrest (OHCA) remains unclear. We aimed to test the association between the number and level of EMTs and the outcomes of patients with OHCA. METHODS We analysed Utstein-based registry data on OHCA in Taipei from 2011 to 2015. The eligible patients were adults, aged ≥20 years, with non-traumatic OHCA who underwent resuscitation attempts. The exposures were the total number of EMTs or the EMT-Paramedic (EMT-P) ratio >50%. The outcome of interest was survival to discharge. RESULTS During study period, total 8262 OHCA cases were included, of which 1085 (13.1%) were approached by crews with an EMT-P ratio >50%. While an increase in the number of EMTs on-scene was not associated with better chances of survival (adjusted odds ratio [aOR] 0.98, 95% confidence interval [CI] 0.89-1.08), an EMT-P ratio >50% was significantly associated with improved outcome (aOR 1.36, 95% CI 1.06-1.76). Subgroup analyses showed that EMT-P >50% significantly benefited survival in witnessed OHCA cases with non-shockable rhythm (aOR 1.69, 95% CI 1.01-2.58). Survival was the highest among cases seen by four EMTs with an EMT-P ratio >50% (aOR 2.54, 95% CI 1.43-4.50). CONCLUSION An on-scene EMT-P ratio >50% was associated with improved survival to discharge of OHCA cases, especially in those with witnessed, non-shockable rhythm. The presence of four EMTs with an EMT-P ratio >50% at the scene of OHCA was associated with the best outcome.

Abstract
OBJECTIVE To investigate the clinical value of detection of circulating tumor cells (CTCs) classified by epithelial cell adhesion molecule (EpCAM) in peripheral blood of patients with non-small cell lung cancer (NSCLC). METHODS Peripheral blood samples (7.5 ml each time) were collected from 47 NSCLC patients. Among them, blood samples were collected at the end of each therapy-cycle in three patients for longitudinal monitoring of CTCs. CTCs were enriched by the depletion of leucocytes using a magnetic bead separation technique, stained with EpCAM, cytokeratin 7/8 and their isotypic control antibodies, respectively, and then identified and counted by multi-parameter flow cytometry. RESULTS In the blood samples from 47 patients, EpCAM-positive CTCs were detected in 64.3%(9/14), 40.0%(4/10) and 43.5%(10/23) of patients in stages Ⅰ-Ⅱ, Ⅲ and Ⅳ, respectively. EpCAM-negative CTCs were detected in 78.6%(11/14), 90.0%(9/10) and 91.3%(21/23) of patients in stage Ⅰ-Ⅱ, Ⅲ, and Ⅳ, respectively. The total detection rates of EpCAM-positive and EpCAM-negative CTCs were 48.9%(23/47) and 87.2%(41/47), respectively, showing a statistically significant difference between them (P<0.001). According to the stage of the cancer, there was a significant difference between the detection rates of the two types of CTCs in patients of stage Ⅳ(P=0.001), but not in stage Ⅰ-Ⅱ and Ⅲ (P>0.05). The number of EpCAM-negative CTCs was significantly higher than that of EpCAM-positive CTCs in all stages (P<0.05). The frequency of patients with the percentage of EpCAM-negative CTCs >90% was significantly higher in stage Ⅳ patients than that in stage Ⅰ-Ⅱ cases (P=0.030), while the frequency of patients with the percentage of EpCAM-negative CTCs between 50%~90% was significantly lower in the stage Ⅳ than that in the stage Ⅰ-Ⅱ patients (P=0.001). The treatment of most patients with EpCAM-negative CTCs >50% showed to be ineffective (P=0.033). CONCLUSION Detection of CTCs classified by EpCAM in peripheral blood is helpful in evaluating the distant metastasis and treatment effectiveness of NSCLC patients.

Abstract
Klebsiella pneumoniae (KP) is the most common pathogen of pyogenic liver abscess in East and Southeast Asia and diabetes mellitus (DM) is a major risk factor. The effect and mechanism of diabetes on KP liver abscess was examined in streptozotocin-induced diabetic mice and Akita mice (C57BL/6J-Ins2Akita). KP translocation to liver and plasma alaine transaminase levels were increased and liver clearance of KP was decreased in DM mice. Diabetic mice exhibited overgrowth of Enterococcus as well as E.coli and decreased lactobacilli/bifidas growth in intestine, increased intestinal iNOS protein and nitrite levels in portal vein, and increased IL-1β and TNF-α expression of Kupffer cells. Fructooligosaccharides (FOS) or dead L. salivarius (dLac) supplementation reversed diabetes-induced enteric dysbiosis, NO levels in portal vein, and KP translocation to liver. L-NAME treatment decreased intestinal iNOS protein expression as well as Kupffer cell activation and increased liver clearance of KP in DM mice. Dead E.coli (2×108 CFU/ml) feeding for one week induced iNOS and TLR4 expression of intestine in germ-free (GF) mice. Dead bacteria feeding induced IL-1β and TNF-α expression of Kupffer cells in GF mice but not in GF TLR4-/- mice. In conclusion, balance of intestinal microflora is important for preventing intestinal iNOS expression, Kupffer cell activation, and KP liver translocation in diabetes. Reversal of diabetes-induced enteric dysbiosis with FOS or dead L. salivarius decreases diabetes-induced intestinal iNOS expression and KP liver translocation. Diabetes induces Kupffer cell activation and KP liver translocation through enteric dysbiosis and nitric oxide production.

Abstract
OBJECTIVE To explore the potential role and mechanism of microRNA(miR)-30a in myocardial fibrosis after myocardial infarction (MI). METHODS Rats were randomly divided into 1 week MI group (n=11), 2 weeks MI group (n=13) and 4 weeks MI group (n=15) by applying random number table after left anterior descending coronary artery ligation. Rats in Sham group were examined at respective time points (n=16). Heart function was monitored by echocardiography. Myocardial collagen volume fraction (CVF) was determined on Masson stained sections. Myocardial expression of collagen Ⅰ and Ⅲ was determined by immunohistochemistry. The myocardial mRNA level of miR-30a, TGF-β1 and CTGF were detected by real time-quantitative PCR analysis. The myocardial protein levels of TGF-β1 and CTGF were measured by Western blot analysis. RESULTS The LVEDD ((8.37±0.58) mm) and LVESD ((6.12±0.82) mm) in 4 weeks MI group were significantly higher than those in Sham group ((6.08±0.57) mm, (4.17±0.60) mm), all P<0.01. The FS ((27.0±3.9) %) and LVEF ((51.0±6.3) %) in 4 weeks MI group were significantly lower than those in Sham group ((47.0±2.1) %, (82.0±2.3)%), all P<0.01. The level of myocardial CVF in 1 week MI group, 2 weeks MI group and 4 weeks MI group were significantly higher than in Sham group (all P<0.01) in a time-dependent manner. The level of myocardial collagen Ⅰ and Ⅲ was increased gradually from 1 week to 4 weeks post MI compared with Sham group (all P<0.01). The collagen Ⅰ/Ⅲ ratio was similar between 1 week MI group and Sham group (P=0.58), however, which was significantly higher in 2 weeks MI group and 4 weeks MI group compared with Sham group (all P<0.01), and the ratio was significantly higher in 4 weeks MI group than 2 weeks MI group (P<0.01). The level of miR-30a was significantly and gradually reduced in all MI groups compared with Sham group (all P<0.01). The mRNA and protein levels of TGF-β1 and CTGF were significantly and gradually increased after MI compared with Sham group (all P<0.001). CONCLUSIONS Our results indicate that overexpression of miR-30a after MI might be a potential strategy for suppressing myocardial fibrosis by modulating the mRNA and protein levels of TGF-β1 and CTGF.

Abstract
Background For large tongue defects, reconstructive surgeons have devised a variety of feasible options, such as radial forearm free flap and anterolateral thigh (ALT) flap. In our institution, peroneal flap has been the workhorse flap for the soft tissue defect in head and neck reconstruction. We present our experience using peroneal flap in tongue reconstruction.
Patients and Methods The study included 47 patients who had undergone tongue reconstructions with peroneal flaps after tumor resection. The size and location of the defect after tumor resection determined whether the peroneal flaps could be harvested as pure septocutaneous flaps to solely reconstruct the neotongue or to carry an additional muscle bulk to fill the adjacent defect. Retrospective chart review was used to look for postoperative complications and to perform functional assessments (which were also performed through telephone inquiry).
Results Of the 47 patients, 3 (6%) had flap failure and 1 (2.1%) had partial flap necrosis. The hemiglossectomy group had better results than the total glossectomy group with respect to speech and diet, but neither of these results reached statistical significance (p = 1.0 for speech and p = 0.06 for diet). The results of the subtotal glossectomy group were better than those of the total glossectomy group with respect to diet (p = 0.03). No statistically significant differences were noted among the three groups with respect to cosmetic aspect (p = 0.64).
Conclusions Considering its reasonable postoperative complication rates and functional results, peroneal flap can be considered a feasible option for tongue reconstruction.

Abstract
Ventilator-associated pneumonia (VAP) is a common nosocomial infection among intensive care unit (ICU) patients. Pseudomonas aeruginosa (PA) is the most common multidrug-resistant Gram-negative pathogen and VAP caused by PA carries a high rate of morbidity and mortality. This study examined the molecular mechanism of PA VAP-induced lung injury. C57BL/6 wild-type (WT) mice and JNK1 knockout (JNK1-/-) mice received mechanical ventilation (MV) for 3 h at 2 days after receiving nasal instillation of PA. The WT and JNK1-/- mice also received MV after the induction of lung injury by instillation of supernatants from PA-stimulated alveolar macrophages (AMs). AMs isolated from WT, IκB-kinase (IKK)βΔMye (IKKβ was selectively deleted in macrophages), and JNK1-/- mice were ex vivo stimulated with live PA and supernatants were collected for cytokine assay. Intranasal instillation of 106 PA enhanced MV-induced NF-κB DNA binding activity in the lungs and nitrite levels in BALF. MV after PA instillation significantly increased the expression of ICAM and VCAM in the lungs and TNF-α, IL-1β, and IL-6 levels in bronchoalveolar lavage fluid (BALF) of WT mice, but not in JNK1-/- mice. MV after supernatant instillation induced more total protein concentration in BALF and neutrophil sequestration in the lungs in WT mice than JNK1-/- mice and cytokine assay of supernatants indicated that TNF-α is a critical regulator of PA VAP-induced lung injury. Ex vivo PA stimulation induced TNF-α production by AMs from WT as well as JNK1-/- mice but not IKKβΔMye mice. In summary, PA colonization plays an important role in PA VAP-induced lung injury through the induction of JNK1-mediated inflammation. These results suggest that the pathogenesis mechanism of PA VAP involves production of TNF-α through activation of IKK/NF-κB pathways in AMs and JNK signaling pathway in the lungs.

Abstract
With increasing use of cardiac fluoroscopic intervention, the incidence of fluoroscopy-induced radiation ulcer is increasing. Radiation ulcer is difficult to manage and currently there are no treatment guidelines. To identify the optimal treatment approaches for managing cardiac fluoroscopy-induced radiation ulcers, we retrospectively reviewed medical records of 13 patients with fluoroscopy-induced radiation ulcers receiving surgical interventions and following up in our hospital from 2012 to 2015. Conventional wound care and hyperbaric oxygen therapy were of little therapeutic benefit. Twelve patients received reconstruction with advancement flap or split thick skin graft. One-stage radical excision of radiation damaged area in eight cases with immediate reconstruction led to better outcomes than conservative excisions in four cases. Radical surgical excision to remove all the radiation damaged tissues in combination with immediate reconstruction appears to offer the optimal treatment results for cardiac fluoroscopy-induced radiation ulcers. Adequate excision of the damaged areas in both vertical (to the muscular fascia) and horizontal (beyond the sclerotic areas) dimension is pivotal to achieve good treatment outcomes.

Abstract
Background Pseudomonas aeruginosa (PA) is the single-most common pathogen of ventilator-associated pneumonia (VAP). Large quantities of PA in the trachea of ventilated patients are associated with an increased risk of death. However, the role of PA colonization in PA VAP-induced lung injury remains elusive. This study examined the effect and mechanism of PA colonization in VAP-induced lung injury. Methods C57BL/6 wild-type (WT) and c-Jun N-terminal kinase knockout (JNK1−/−) mice received mechanical ventilation for 3 h at 2 days after receiving nasal instillation of PA (1 × 106 colony forming unit) or normal saline. Results Intranasal instillation of PA or mechanical ventilation induced the expression of interleukin-6 (IL-6) in the lungs. Phospho-JNK protein expression in the lungs was significantly increased in mice receiving mechanical ventilation after PA instillation as compared with those receiving ventilation alone. Mechanical ventilation after PA instillation significantly increased the expression of tumor necrosis factor-α (TNF-α), IL-1β, and macrophage inflammatory protein-2 (MIP-2) proteins; neutrophil sequestration; and TNF-α, IL-1β, and IL-6 levels in the lungs of WT mice, but not in JNK1−/− mice. Conclusion PA colonization plays an important role in PA VAP-induced lung injury through the induction of JNK1-mediated inflammation. PA-induced VAP causes lung injury through JNK signaling pathway in the lungs. JNK inhibition in ICU patients with higher percentages of PA colonization may reduce VAP-induced lung injury and mortality.

Abstract
With increasing numbers of percutaneous coronary intervention (PCI) and complex cardiac procedures, higher accumulated radiation dose in patient has been observed. We speculate cardiac catheter intervention induced radiation skin damage is no longer rare.To study the incidence of cardiac fluoroscopic intervention induced radiation ulcer. We retrospectively reviewed medical records of those who received cardiac fluoroscopic intervention in our hospital during 2012 to 2013 for any events of radiation ulcer. Only patients, whose clinical photos were available for reviewing, would be included for further evaluation. The diagnosis of radiation ulcers were made when there is a history of PCI with pictures proven skin ulcers, which presented typical characteristics of radiation injury. Nine patients with radiation ulcer were identified and the incidence was 0.34% (9/2570) per practice and 0.42% (9/2124) per patient. Prolonged procedure time, cumulative multiple procedures, right coronary artery occlusion with chronic total occlusion, obesity, and diabetes are frequent characteristics. The onset interval between the first skin manifestation and the latest radiation exposure varied from 3 weeks to 3 months. The histopathology studies failed to make diagnosis correctly in 5 out of 6 patients. To make thing worse, skin biopsy exacerbated the preexisting radiation dermatitis. Notably, all radiation ulcers were refractory to conventional wound care. Surgical intervention was necessary to heal the wound. Diagnosis of cardiac fluoroscopy intervention induced radiation skin damage is challenging and needs high index of clinical suspicion. Minimizing the radiation exposure by using new approaches is the most important way to prevent this complication. Patient education and a routine postprocedure dermatology follow up are mandatory in high-risk groups for both radiation skin damage and malignancies. This is a retrospective study, thus the true incidence of radiation ulcer caused by cardiac fluoroscopic intervention could be higher.

Abstract
Abstract
Systemic inflammation appears to persist in diabetic patient. To examine the role of reactive oxygen species (ROS) of intestine in DM-induced inflammation, streptozotocin (STZ)-induced diabetes and Ins2Akita (Ins2Akita mutation mutant) mice were used. STZ mice demonstrated a significant decrease of Lacobacilli as well as ROS production and a marked increase of p-JNK as well as iNOS expression in the intestinal mucosa. Oral supplementation of fructooligosaccharides (FOS) or dead Lacobacilli increased the production of ROS of intestine and decreased IL-1β expression of Kupffer cells in STZ and Ins2Akita mice. Feeding of L-NAME, an iNOS inhibitor, but not D-NAME increased the production of ROS of intestinal mucosa and decreased endotoxin in portal vein and IL-1β expression of Kupffer cells in STZ mice. Oral feeding of N-Acetylcysteine, a ROS scavenger, decreased ROS production and inhibited the effects of FOS as well as L-NAME on reversing DM-induced ICAM expression of liver. Using STZ JNK1-/- and Ins2Akita JNK1-/- mice to reverse DM-induced pJNK expression of intestinal mucosa induced a significant decrease of IL-1β expression of Kupffer cells and ICAM expression of liver. Collectively, diabetes induces systemic inflammation through decreasing ROS production and increasing pJNK expression of intestine. Increasing intestinal ROS production could reverse diabetes-induced systemic inflammation.

Abstract
Abstract
Microbiota maintains normal mucosal immunity through complex mechanisms. To examine the role of JNK signaling pathway in microbiota-related gut immunity, we assessed the microflora in ileal lumen and mucosa, the antibacterial protein expression, and the RORγt cells of lamina propria in WT and JNK-/- mice. The bacterial counts in ileal lumen and mucosa show a significant decrease of Lacobacilli in JNK-/- mice. Moreover, JNK-/- mice demonstrated a significant decrease of RORγt cells in lamina propria and an increased translocation of Klebsiella pneumoniae to the portal vein as well as blood. The generation of reactive oxygen species (ROS) in intestinal mucosa was also significantly decreased in JNK-/- mice as detected by using 2',7'-dichlorodihydrofluorescein diacetate. Oral supplementation of fructooligosaccharides (FOS) or L-NAME but not D-NAME increased the production of ROS, IL-1β, IL-23 as well as RORγt cells in intestine, and decreased the translocation of K. pneumoniae in JNK-/- mice compared to WT mice. N-Acetylcysteine, an antioxidant, treatment inhibited ROS production and reversed the effect of FOS on intestinal immunity in JNK-/- mice. Collectively, JNK pathway plays an important role in microbiota-induced intestinal immunity through the induction of ROS generation, and FOS or iNOS inhibitor increase the numbers of RORγt cells and the expression of IL-1β as well as IL-23 in JNK-/- mice through enhanced production of ROS.

Abstract
To improve the functional properties of peanut meal protein for wide utilization, hydrolysis was conducted by alcalase. Compared with saline and peanut meal protein, intragastric administration of low molecular weight (<1 kD) peanut meal peptide (PPH I) could significantly prolong swimming time, increase levels of blood sugar, non-esterified fatty acids (NEFA) and liver glycogen and decrease blood lactate content in mice. Levels of Pro, Leu, Val and His in low molecular weight peanut meal peptides were higher significantly than those in other peanut meal protein hydrolysates. Hydrophobic amino acids, such as Pro, Tyr and His, could perhaps capture free radical and increase antioxidant capacity of peanut peptide and retard fatigue induced by free radical. After separation by HPLC, a primary peptide P1, Pro-Glu-Ile-Glu-Val, was sequenced. Its N-terminal was Val, and it was rich in antioxidant amino acid, Pro and Ile. Levels of plasma glucose, NEFA and liver glycogen in PPH I group were higher than those in mice intragastric administration with peptide P1, and the swimming time is longer in PPH I group than in P1 group. So, the high content of P1 was one of the reason why PPH I had high endurance-enhancing capacity.
