Abstract
BACKGROUND The advent of effective adjuvant therapies for patients with resected melanoma has highlighted the need to stratify patients based on risk of relapse given the cost and toxicities associated with treatment. Here we assessed circulating tumor DNA (ctDNA) to predict and monitor relapse in resected stage III melanoma. PATIENTS AND METHODS Somatic mutations were identified in 99/133 (74%) patients through tumor tissue sequencing. Personalized droplet digital PCR (ddPCR) assays were used to detect known mutations in 315 prospectively collected plasma samples from mutation-positive patients. External validation was performed in a prospective independent cohort (n = 29). RESULTS ctDNA was detected in 37 of 99 (37%) individuals. In 81 patients who did not receive adjuvant therapy, 90% of patients with ctDNA detected at baseline and 100% of patients with ctDNA detected at the postoperative timepoint relapsed at a median follow up of 20 months. ctDNA detection predicted patients at high risk of relapse at baseline [relapse-free survival (RFS) hazard ratio (HR) 2.9; 95% confidence interval (CI) 1.5-5.6; P = 0.002] and postoperatively (HR 10; 95% CI 4.3-24; P < 0.001). ctDNA detection at baseline [HR 2.9; 95% CI 1.3-5.7; P = 0.003 and postoperatively (HR 11; 95% CI 4.3-27; P < 0.001] was also associated with inferior distant metastasis-free survival (DMFS). These findings were validated in the independent cohort. ctDNA detection remained an independent predictor of RFS and DMFS in multivariate analyses after adjustment for disease stage and BRAF mutation status. CONCLUSION Baseline and postoperative ctDNA detection in two independent prospective cohorts identified stage III melanoma patients at highest risk of relapse and has potential to inform adjuvant therapy decisions.

Abstract
Parasite classification and identification are central to controlling parasitosis. Traditional methods for identifying parasite species are based on morphological features, but these are time-consuming and inaccurate, especially for cryptic species. The purpose of the present study was to select molecular markers to promote the development of molecular systematic for parasites. The internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA) falls in between 18S, 5.8S, and 28S rDNA sequences, including ITS-1 and ITS-2 sequences. Previous studies have demonstrated that rDNA ITS sequences provide useful genetic markers for identifying parasitic nematodes. With the ultimate goal of controlling parasite transmission, we identified Kalicephalus belonging to three species using ITS rDNA genes. The ITS genes (750-797 bp) of 21 Kalicephalus belonging to 3 species were cloned and sequenced. Intra- and interspecific identities were 98.4% and 80%-89%, respectively. The phylogenetic tree reconstructed with the neighbour-joining (NJ) method revealed that congener Kalicephalus form the same branch, which is far apart from other branches of other nematodes. This is consistent with morphological classifications, demonstrating the accuracy of our molecular method. This is the first report stating that ITS genes can be used to classify Kalicephalus, and it lays the foundation for identification, molecular epidemiology, and phylogenetics of Kalicephalus and related parasitic nematodes.

Abstract
Segmental defects are formidable challenges for orthopedic surgeons that are caused by large osseous defects such as open injury, comminuted fracture as well as other severe traumas and infection. Current treatment options have practical and clinical shortcomings, calling for innovative bone graft materials. This study is related to hollow tubular magnesium‑strontium (MgSr) alloy scaffolds with autologous morselized bone filled inside and three different coatings were individually applied on MgSr scaffolds, respectively, to study the effects of degradation and bioactivity of the grafts on new bone growth. The optimal coating method was screened using immersion tests, cell proliferation and adhesion, alkaline phosphatase (ALP) assay in vitro, and 4 weeks' implantation in a critical-size segmental defect in vivo. More new bone formation was observed by radiographic tests and histology along the ulna defects, when magnesium scaffold grafts were implanted. Meanwhile, depression occurred for blank control group with only autologous morselized bone filled, because of rapid absorption rate of morselized bone during initial implantation. Therefore, biodegradable MgSr alloy grafts showed their potential application in treating the critical-size segmental defects. As for different coating methods, CaP chemically deposited (CaP) coated sample showed least H2 evolution in vivo, demonstrating highest corrosion resistance and relative stable interfaces, however, the least beneficial ion release meanwhile. Micro-arc oxidation coating (MAO) degraded faster comparing with CaP, while with the main composition of MgO. They both indicate insufficient bioactivity in bone formation. The results suggest superior combination of bioactive surface, beneficial ions release and appropriate corrosion rate of Strontium phosphate conversion (SrP) coating, indicating superior comprehensive oeteoconductive and osteoinductive properties of coatings on hollow tubular MgSr alloy scaffold.

Abstract
Background: Circulating tumor cells (CTCs) display changes in epithelial-mesenchymal transition (EMT) markers and miRNAs regulate EMT in breast cancer cells. The association between EMT characteristics and miRNA expression in CTCs of metastatic breast cancer (MBC) patients and their clinical implications remain unknown.
Methods: CTC-specific miRNAs were screened based on comparison of the miRNA profile between CTC and primary tumor. RT-PCR was used to quantity the expression levels of EMT makers and miRNA candidates. We enrolled 219 MBC patients with CTCs ≥ 5/7.5mL blood from 2 cohorts and CTCs were detected and enriched by CellSearch. Overall survival (OS) and radiological response were analyzed. CTCs were divided into epithelial- (E-CTCs) and mesenchymal-like CTC (M-CTCs) phenotypes based on a cut-off value derived from suspended breast cancer cells recovered from PBMCs.
Results: MiR-106b displayed upregulation in CTCs, with a higher level in M-CTCs than E-CTCs. Patients with E-CTCs showed better OS than those with M-CTCs (HR 1.77, 95% CI 1.14-2.78, P =0.012). CTCs from chemo-resistant MBC patients exhibited higher miR-106b. CTC-specific miR-106b was negatively associated with therapy response and OS (HR 1.73, 95% CI 1.06-2.84, P = 0.029).
Conclusions: CTC-specific miR-106b was associated with EMT phenotypes of CTCs and may predict prognosis in MBC patients.

Abstract
Abstract
Background It is still controversial to consider age as a prognostic factor into the treatment strategy of patients with T1N0M0 breast cancer.
Aim The main purpose of this study was to evaluate the effect of age on recurrence risk in patients diagnosed with T1N0M0 breast cancer as well as compare the prognosis of young aged patients(YA,≤40 years old) to non-young aged patients(non-YA,>40 years old) by using a propensity score matching(PSM) analysis.
Methods 365 patients with T1N0M0 breast cancer diagnosed between 2003 and 2016 who received surgery in Sun Yat-sen Memorial Hospital Breast Cancer Center were included.The recurrence free survival (RFS) and risk factors for recurrence were identified by using Kaplan-Meier method and Cox proportional hazards models. PSM was then used to reduce the confounding effect of known risk factors on prognosis and then to compare 5-year RFS rates in patients between two age groups.
Results After a median follow up of 79 months, 54 patients developed recurrences and 5-year RFS was 87.6%. YA patients had lower RFS estimates (80.6%), compared to patients diagnosed in a later age (89.1% if older than 40-years old; P = 0.049). YA patients tended to have Her-2 positive, TNBC tumors, higher rate of Ki-67 expression and nuclear grade tumor. At multivariate analysis, Her-2 positive (HR 2.115; 95% CI 1.103-4.055, p=0.024) and TNBC (HR 2.963; 95% CI 1.485-5.914, p=0.002) resulted independent prognostic factors of patient with T1N0M0 breast cancer. In the subgroup analysis, we found significant poor RFS for YA patients with Her-2 positive breast cancer compared to the older counterparts(p=0.006) and YA patients were associated with significantly higher rates of the locoregional recurrence rather than metastasis(p=0.004), especially in first 5 years after diagnosis. After PSM, the baseline level and treatment status including tumor size, grade, HR status, Her-2 status, Ki67 expression breast surgery type and systemic adjuvant treatment(AST) of patients in the two age groups tended to be equal. As result, we found significant difference in the 5-year RFS between two age groups(p=0.008).
Conclusion Based on equal treatment condition, young age at presentation conferred a worse prognosis in patients with T1N0M0 breast cancer is independent on other pathological features.

Abstract
Abstract
Purpose
The aim of the study was to develop a specific nomogram for prediction of prognosis for breast Paget's disease with infiltrating ductal carcinoma (PD-IDC) patients.
Patients and Methods
Patients data were obtained by the Surveillance, Epidemiology, and End Results (SEER) program (N=2502). Study outcome was Breast Cancer Specific Survival (BCSS). Cox proportional hazards model was applied to identify risk factors and develop predictive model. For internal validation, discrimination was calculated with the concordance index (C-index) using the bootstrap method and calibration assessed.
Results
NPI classification, skin symptom, tumor site and age showed significant association with BCSS(table.1)and were used to build the PDIDC nomogram and to calculate risk score. PDIDC nomogram's C-index (0.791, 95%CI 0.783-0.818) showed better discrimination power than NPI classification (0.691, 95%CI, 0.650-0.735, P= 0.000) and AJCC staging (0.718, 95%CI, 0.695-0.741, P=0.000). Patients were divided into high-risk (1882/2502, 75.21%) and low-risk (620/2502, 24.78%) subgroups with the optimal cut-off of risk scores (4.28). The total BCSS of low-risk subgroup was 77.8% (95%CI 74.4%-81.4%) vs. 31.1% (95%CI 19.4-49.8) of high-risk group (P=0.000). Bootstrap internal validation demonstrated an average C-index of 0.739 (95% CI, 0.692-0.746). The nomogram calibration was validated to be accurate in predicting 5-year and 10-year survival.

Abstract
Nasal irrigation is a common topical treatment in rhinology. Saline irrigation(SI) is the most common and basic way of nasal irrigation. Mechanisms of action of SI contain physical clearance, regulation of nasal mucociliary function, enhancement of antimicrobial activity of nasal secretions and the effects of ions.Current solutions for SI differ in composition and physicochemical properties, specifically presence of additional ions, concentration of saline, pH values and temperature. Positive pressure should be an optimized method of SI. The side effects of SI include nasal discomfort, otalgia, and pooling of saline in sinuses with subsequent drainage. Furthermore, solutions are at the risk of contamination in SI.Despite the widely use of SI in the therapy of acute upper respiratory tract infections, allergic rhinitis, chronic rhinosinusitis and vasomotor rhinitis, evidence is still insufficient to support it. Researches in the use of SI on children is urgently needed.

Abstract
Taenia multiceps, one of the most widely distributed zoonotic tapeworm parasites, is able to parasitize the small intestine of canids. The metacestode of T.multiceps is fatal to ruminants and causes important economic losses in livestock. However, molecular characteristics of T.multiceps and coenurus in China are still unclear. In this study, 36 goat isolates of the coenurus stage and 18 dog isolates of the adult stage of T.multiceps were obtained from three geographical areas in China and the isolated parasite above were analyzed by amplifying the partial of cytochrome coxidase subunit 1(pcox1), 12S ribosomal RNA (12S rRNA) from mitochondrial DNA (mtDNA) regions and an internal transcribed spacer (ITS) of ribosomal DNA (rDNA). These DNA sequences obtained from T.multiceps and coenurus were employed to evaluate the nucleotide diversity and confirm the relationship between T.multiceps and coenurus. Sequences variation were 0-1.4%, 0-1.5%, 0-4.2% for pcox1, 12S rRNA and ITS, respectively, among T.multiceps and coenurus isolates obtained in this study. In Sichuan province, sequence variations for Coenurus cerebralis isolated from Yaan city were 0-1.4% for pcox1, 0-1.0% for 12S rRNA and 0-2.1% for ITS. In Hunan province, variations were 0-1.0%, 0-1.5% and 0-3.3% for corresponding genes for non-coenurus cerebralis isolated from Changsha city, while variations of T.multiceps isolates from Xiangxi autonomous prefecture were 0-1.0%, 0-1.1% and 0-3.4% for pcox1, 12S rRNA and ITS, respectively. Phylogenetic analysis based on pcox1 sequences indicated that all cerebral and noncerebral metacestodes belong to T.multiceps. These results provide reference values for future molecular epidemiological and biological study on T.multiceps in dogs and intermediate hosts.

Abstract
OBJECTIVE Hepatic encephalopathy is a common consequence of liver cirrhosis, but diagnosis can be difficult as it is based on clinical criteria alone. We hypothesised that serum prealbumin, cholinesterase and retinol binding protein (RBP) can help support the diagnosis of hepatic encephalopathy. METHODS We enrolled 306 cirrhotic patients (110 with encephalopathy), 100 chronic hepatitis B patients and 50 healthy controls, measuring routine liver function tests (ALT, AST, GGT, ALP, and bilirubin), albumin, prothrombin time, prealbumin, cholinesterase and RBP by routine methods. Logistic regression analysis and areas under the receiver operating characteristic curves (AUCs) were used to find predictive factors for hepatic encephalopathy. RESULTS There were differences in all laboratory indices between the three groups (all p < 0.001). In univariate analysis, albumin, prothrombin time, prealbumin, cholinesterase and RBP were significantly altered in those with encephalopathy (p < 0.01), but only prealbumin, cholinesterase and RBP levels were significant predictors in multivariate analysis, and each was linked to the severity of liver fibrosis defined by the Child-Pugh score (all p < 0.001). The AUCs (95% CI) of prealbumin, cholinesterase and RBP for diagnosing liver cirrhosis with hepatic encephalopathy were comparable at 0.85 (81-90), 0.81 (0.76-0.85) and 0.81 (0.76-0.86), respectively (all p < 0.01). CONCLUSIONS Serum prealbumin, cholinesterase and RBP levels are of potential clinical value in diagnosis of liver cirrhosis complicated by encephalopathy.

Abstract
OBJECTIVE To compare the efficacy and safety between ozonated oil and compound flumethasone ointment in the treatment of psoriasis vulgaris.
Methods: A left/right self-controlled, parallel group study was conducted. Forty patients with stable psoriasis vulgaris were enrolled in the study, whose lesions were symmetrical and involvement areas were <30% body surface. The patients were divided into 2 groups. Patients with left lesions served as a test group were treated daily for ozonated oil twice, and patients with right lesions served as a control group were treated daily for compound flumetasone ointment twice. The patients in the 2 groups were treated for 4 weeks. The clinical efficacy and safety were observed at 1, 2 and 4 weeks after the treatment.
Results: After 1 week treatment, the effective rates of the test group and the control group were 60.58% and 72.28%, respectively, with significant difference between them (P<0.05). At 2 weeks and 4 weeks after the treatment, the efficacy in the test group was similar to that in the control group. The effective rates in the test group and the control group were 69.84% and 70.25% after 2 weeks, respectively, 70.88% and 71.23% after 4 weeks, respectively. There was no significant difference between the 2 groups (P<0.05). In addition, the reflectance confocal microscope results in both the test group and the control group after 4 weeks showed that the epidermis was approximately normal. There were few inflammatory cells infiltration in the dermal papilla, and the inflammatory cells infiltration was significantly reduced after treatment.
Conclusion: Ozonated oil treatment for stable psoriasis is safe and effective, and its efficacy is equivalent to the effect of glucocorticoid topical preparations.

Methods: This was a randomized controlled trial study, prospective collection of patients' data who were diagnosed as subacromial impingement syndrome at Orthopedic of Tianjin Fifth Central Hospital from January 2015 to August 2017. To ensure the randomness of the study, patients were randomized into two groups using a random number table. Pain(visual analogue scale(VAS)) and shoulder function (University of California Shoulder Score System(UCLA) and shoulder abduction) were performed before and after each injection.For continuous endings with multiple points in time, firstly, the normality, the homogeneity of variance, and the sphericity test of Mauchly were performed. After the condition was satisfied, the variance analysis of the two-factor repeated measurement data was performed. Results: Fifty-two patients completed the injection within 5 minutes and 41 patients got the final follow-up. Twenty-two patients in the corticosteroid group, 14 males and 8 females, aged (44.7±9.5) years old(range: 35-68 years old). The lesion involved 13 cases of superior shoulder, more than 1 time injection in 4 cases. There were 19 patients in the NSAID group, 7 males and 12 females, aged (37.2±10.1) years old(range: 27-63 years old), 10 cases with lesions involving superior shoulders, and 1 case with more than one injection. (1)VAS score: compared with pre-injection(Corticosteroid group 5.0(4.0-6.0)and NSAIDS group 5.0(4.0-6.0)), both groups showed significant pain relief at 60 minutes(1.0(1.0-2.0)and 1.0(1.0-2.0)) and 6 weeks(1.5(1.0-2.0)and 1.0(1.0-2.0)) after injection(χ2=47.293, 41.173, 45.174, 40.113; P<0.01). (2)UCLA score: compared with pre-injection(30.2±2.5 and 30.5±3.0), UCLA scores improved significantly in both groups at the 6-week after injection(Corticosteroid group: MD=9.727, t=19.218, P<0.001; NSAID Group: MD=9.579, t=11.467, P<0.01). The UCLA score improvement between the two groups was no statistical difference(all P>0.05). (3)shoulder abduction degree: compared with pre-injection(92.7±9.4 and 93.2±11.6), the abduction degree was significantly improved in both groups at 60 minutes(131.8±9.6 and 127.4±16.6) and 6 weeks(115.9±9. 1 and 127.9±14.4) after the injection, but the improvement in each time point has no statistical correlation(MD=4.450, t=1.069, P=0.292). NSAID group had better improvement of shoulder abduction degree than corticosteroid group at the 6 weeks after the injection(MD=-11.986, t=-3.238, P=0.002). Conclusions: Ultrasound-guided subacromial injection can reduce pain in patients with subacromial impingement syndrome.The effect of injection of NSAID drugs is the same as corticosteroid drugs, it can avoid hormone-induced complications and reduce the repeat of the punctures.

Abstract
Organic luminescent materials with the ability to reversibly switch the luminescence when subjected to external stimuli have attracted considerable interest in recent years. However, the examples of luminescent materials that exhibit multiresponsive properties are rarely reported. In this work, a new stimuli-responsive dye P1 is designed and synthesized with two identical chromophores of naphthalimide, one at each side of an amidoamine-based spacer. This amide-rich molecule offers many possibilities for forming intra- and intermolecular hydrogen bond interactions. Particularly, P1 has an intrinsic property of cocrystallizing with methanol. Compared with the pristine P1 sample, the as-prepared two-component cocrystalline material displays an exceptive deep-blue emission, which is extremely rare among naphthalimide-based molecules in the solid state. Furthermore, the target material exhibits an obvious mechanochromic fluorescent behavior and a large spectral shift under force stimuli. On the other hand, the cocrystalline material shows an unusual "turn off" thermochromic luminescence accompanied by solvent evaporation. Moreover, using external stimuli to reversibly manipulate fluorescent quantum yields is rarely reported to date. The results demonstrate the feasibility of a new design strategy for solid-state luminescence switching materials: the incorporation of solvents into organic compounds by cocrystallization to obtain a crystalline state luminescence system.

Abstract
Liver ischemia/reperfusion injury (IRI) occurs during partial liver resection and liver transplantation. Activation of Toll-like receptors (TLRs) is a key event triggered by a range of proinflammatory cytokines during liver I/R. Although it has been reported that miR-155 takes part in both innate and adaptive immune responses, the potential role of miR-155 in liver IRI remains unknown. In this study, we found that expression of miR-155 was upregulated during liver I/R by many inflammatory cytokines, and forced expression of miR-155 aggravated hepatocyte injury following liver I/R both in vivo and in vitro. Mice transfected with Ago-miR-155-a chemically modified miR-155-showed enhanced liver severity compared to those transfected with negative control miRNA by inhibiting the expression of SOCS1, the target of miR-155. Thus by the inhibition of SOCS1, the overexpression of miR-155 promoted activation of NF-κB, and elevating the production of proinflammatory cytokines, such TNF-α and IL-6. In conclusion, miR-155 aggravates liver I/R injury in vivo and hepatocyte hypoxia/reoxygenation injury by suppressing the expression of SOCS1.
