Abstract
The number and spatial configuration of the screws will affect the stability and prognosis of the fractures. In our study, we assessed the biomechanical effects of the double-head cannulated compression screw (DhCCS) and ordinary cannulated compression screw (OCCS) for the treatment of femoral neck fractures by using computer finite element analysis. The original digital imaging and communications in medicine (DICOM)data of a proximal femur were imported into Materialise's interactive medical image control system (MIMICS)software for modeling. Both DhCCS and OCCS 3D-models were obtained by using the 3D scan technique. Using the fracture model and internal fixation assembly model with an inverted triangle, two horizontal and vertical distribution were established in UG software. Next, the displacement and stress distribution were calculated in ANSYS software. The displacement value of the femoral head in the DhCCS group was smaller than that in the OCCS group, and the displacement value in the two horizontal groups was smaller than that in the vertical group. The stress distribution in the DhCCS group was concentrated on the screw rod at the fracture block and thread end, while only at the fracture block in the OCCS group. The stress in the horizontal group was more dispersed on the screws than that in the vertical group. DhCCS has reliable stability for the fixation of femoral neck fractures and applied in the clinical work and 2 horizontal fixation can be used when two screws are selected.

Abstract
OBJECTIVE Extensive incision associated with large-scale callus exfoliation and internal fixation is the common therapeutic approach employed by the majority of orthopaedists in the treatment of old femoral fractures. Inspired by the surgical techniques of intramedullary fixation and reduction by traction, the present study attempted to treat old femoral fractures with minimally invasive methods utilising the principles of biological osteosynthesis (BO). METHODS A retrospective analysis involving 16 patients with old femoral fractures treated with combined traction, small incision, limited callus treatment, reduction by leverage and intramedullary fixation was conducted. The operative effect was evaluated by the operation time, intraoperative blood loss, bone grafting, healing time of fractures during follow-up, VAS score, and Harris hip score. RESULTS Intraoperative observation revealed an average operation time of 1.53 ± 0.34 h and average blood loss of 268.13 ± 97.29 ml without bone grafting in all patients. All enrolled patients had outcomes resulting in effective fixation restoration of limb alignment. Of the 16 enrolled patients, 13 patients completed follow-up with an average follow-up time of 7.42 ± 3.29 months. The average healing time for proximal femoral fractures was 3 months. The average healing time of femoral shaft fractures was 4 ± 1.09 months; two of these cases took 4 months to heal, whereas 1 case demonstrated a delayed healing time of 6 months. The VAS score was 1.15 ± 1.70, 1 patient experienced sciatica, and the Harris hip score was 92.92 ± 5.42. There were no complications of malunion, nonunion or infection among any of the patients who completed follow-up. CONCLUSIONS Minimally invasive treatment is feasible for most patients with old femoral fractures of the trochanter and femoral shaft. This finding is consistent with BO principles, thereby providing a possible new method for the treatment of old femoral fractures.

Abstract
Objective: To explore the efficacy of tenofovir disoproxil and adefovir dipivoxil treatment in patients with hepatitis B virus e antigen (HBeAg) negative was analyzed through the comparison of highly sensitive HBV viral load monitoring with HBV genotyping and drug resistance mutations. Methods: The clinical data of newly diagnosed chronic hepatitis B patients from January 2015 to June 2017 in outpatients and inpatients were randomly divided into tenofovir and adefovir group. Quantitative detection of HBV DNA levels before therapy and at 12, 24, 48, 96, and 120 weeks after therapy were determined for HBV genotypes and drug-resistant mutations in HBeAg-negative patients. Student's t-test was used to compare the measurement data between groups. The data of comparison between groups were tested by χ (2). Results: A total of 106 cases of HBeAg-negative patients were collected. Tenofovir disoproxil had a higher rate of HBV DNA suppression (54%) than adefovir dipivoxil treatment (42%), but the difference was not statistically significant (P = 0.19). After 120 weeks of treatment, a total of 46 patients (93.9%) were enrolled in the tenofovir disoproxil group with HBV DNA quantitation < 2 000 IU / ml. Adefovir dipivoxil group of patients with HBV DNA < 2 000 IU / ml a total of 40 cases, accounting for 75.5%. The difference between the two groups was statistically significant (P < 0.05). For 49 cases of HBeAg-negative patients, HBV B, C, B and C were mixed before tenofovir dipivoxil treatment, and C1653T, A1762T and G1764A mutation sites were detected in patients with D genotype. Patients C, B, C, B, and C were examined for C1673T, G1896, G1858, G1899A. After treatment, the detection rate of the above mutation sites decreased, but C1653T, C1673T and G1899A were not detected. New mutation sites such as G1915A / C, L180M, M204V, V207I / L, T184A and V173L were detected, Low resistance rate (25%). Conclusion: Tenofovir disoproxil can be recommended as a treatment for HBeAg-negative patients. For HBeAg-negative patients, the choice of high-sensitivity detection of HBV DNA levels, better monitoring of anti-HBV efficacy.

Abstract
Intervertebral disk degeneration (IDD) is a common disease that is caused by degeneration of the nucleus pulposus (NP). One goal in the treatment of IDD is delaying or reversing the degeneration of NP via the transformation of exogenous genes. This study first investigated the role of BMP9 in the extracellular matrix (ECM) of nucleus pulposus cells (NPCs) and its mechanism. We found that BMP9 promotes the expression of ECM in NPCs, and the key molecules of Notch signaling, namely, NICD-1, hes and hey, and it was significantly altered in BMP9-transfected NPCs, which suggests that BMP9 may regulate the ECM via the Notch signaling pathway. We verified the expression of Notch ligands and receptors in NPCs infected with Ad-BMP9 and demonstrated a significant decrease in DLL1 and Notch1; then, NPCs were transfected with Ad-dnNotch1, Ad-Jagged1, and Ad-DLL1, and different multiple groups were established to further identify the ligands or receptors that affected ECM expression. The results demonstrated that Ad-dnNotch1, Jagged1 and DLL1 inhibited ECM expression, and dnNotch1 promoted expression. Therefore, we demonstrated that BMP9 promoted the expression of ECM in NPCs via inhibition of Notch1 and DLL1. This study provides a possible method for IDD treatment.

Abstract
An increasing number of unruptured intracranial aneurysms (UIAs) has been
discovered in elderly patients in recent years, but the optimal treatment
strategy for these patients remains controversial. We report our six-year
experience treating UIAs in elderly patients (≥ 70 years old). A retrospective
review was conducted of elderly patients who harbored UIAs treated by
conservative observation, microsurgical clipping, or endovascular coiling
between January 2009 and December 2014. The patients’ clinical and imaging
information was recorded. Treating methods, procedure-related complications,
imaging results, and clinical outcomes were analyzed. A total of 141 consecutive
elderly patients with 166 UIAs were enrolled in our study. In all, 64 patients
with 79 aneurysms were treated with coiling, and 14 patients with 14 aneurysms
were treated with clipping. The remaining 63 patients with 73 aneurysms were
placed under conservative observation. The average modified Rankin scale was
0.99 (range 0–6) in the full cohort after a mean follow-up of 50.4 months (range
0–70 months). There was no significant difference of modified Rankin scale in
patients with UIAs treated by different methods. Multivariate analysis showed
that age (p=0.030) and aneurysm size (p=0.011)
were independent risk factors for unfavorable outcome of UIAs in the elderly.
Patient age (p=0.010) and aneurysm size
(p=0.020) were also significantly associated with unfavorable
outcome of UIAs managed with observation initially. Our results indicated that
endovascular coil embolization and clipping were both safe and effective
treatment methods for UIAs in the elderly. Aggressive treatment for UIAs in
elderly patients with risk factors of aneurysm rupture should be considered
positively.

Abstract
Objective: To analyze the composition and richness of intestinal microflora in children with non-alcoholic fatty liver disease (NAFLD) and the role of which in pathogenesis of NAFLD. Methods: This was a prospective case-control study. From November 2015 to June 2017, 19 children diagnosed with NAFLD according to the 2010 edition of diagnostic criteria were enrolled voluntarily in the Second and First Affiliated Hospitals of Zhejiang Chinese Medicine University. Twenty-two healthy children were enrolled in the control group. Among the patients, 10 were males and 9 were females, at the mean age of (11.0±1.0) years; 10 males and 12 females in the control group, at the mean age of (9.0±1.2) years. The body mass index (BMI) and waist circumference were recorded, and the fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein were detected. Feces were collected and the fecal microorganisms were extracted with magnetic beads methods; the composition and the richness of intestinal microflora in the two groups were detected with 16S rDNA high throughput sequencing technology. The KO differential gene expression and KEGG signal pathway enrichment were analyzed with PICRUST software. The intestinal flora characteristics between the two groups were compared with t test or Mann-Whitney U test and Willcoxon W test. Results: The BMI, waist circumference and triglyceride were higher in NAFLD group than those in the control group (BMI (25.1±2.7) vs. (18.2±1.5)kg/m(2), t=9.912, P=0.000; waist circumference (88.6±6.6) vs. (71.5±6.3) cm, t=8.520, P=0.000; triglyceride (0.9±0.4) vs.(0.7±0.3)mmol/L, t=2.060, P=0.046). The abundance and diversity index of intestinal microflora were lower in the NAFLD group (Shannon index 3.99 (3.13, 4.54) vs. 4.63 (4.21, 4.81), Z=-2.065, P=0.039; Simpson index 0.85 (0.70, 0.89) vs. 0.90 (0.88, 0.93), Z=-2.431, P=0.015; ACE index 235.76 (205.26, 361.94) vs. 326.96 (275.34, 368.65), Z=-2.092, P=0.036). At the level of phylum, the proportion of Actinomycetes was lower and the proportion of Thermus was higher in NAFLD group (Actinobacteri 29.807 (14.723, 62.080) ×10(-3) vs. 63.212 (46.133, 172.071) ×10(-3), Z=-2.667, P=0.008; Thermus 0.033 (0.000, 0.226) ×10(-3) vs. 0.000 (0.000, 0.031) ×10(-3), Z=-2.729, P=0.006) . At the level of genus, the proportion of Bacteroides and Bifidobacterium in the NAFLD group were significantly lower (Bacteroides 78.757 (11.430, 151.621) ×10(-3) vs. 356.821 (161.049, 403.037) ×10(-3), Z=-2.771, P=0.006; Bifidobacterium 19.680 (6.181, 53.944) ×10(-3) vs. 54.721 (31.911, 146.410) ×10(-3), Z=-2.458, P=0.014); the proportion of Prevotella in NAFLD group was significantly higher (3.089 (0.165, 63.502) ×10(-3) vs. 0.432 (0.029, 2.257) ×10(-3), Z=-2.112, P=0.035). Based on the KEGG database, 78 differentially expressed genes and 26 differential metabolic pathways were found, among which the function genes of K01470, K01961 and K07258 were concentrated in the pathways of arginine and proline metabolism, fatty acid synthesis, and polysaccharides biosynthesis and metabolism. Besides, these three function genes were related to Bacteroides, Prevotella, Bifidobacterium and Ruminococcus. Conclusion: NAFLD children have intestinal flora disturbances in both diversity and abundance, which may alter lipid metabolic pathways through differential gene expressions, contributing to the pathogenesis of NAFLD.

Abstract
B7H4 is overexpressed in human cancers and often correlates with poor clinical outcome. There is a lack of data on the role of B7H4 as a cancer stem cell (CSC) regulator in esophageal squamous cell carcinoma (ESCC) and its expression levels compared to other stemness genes in ESCC. In this study, we have assessed the expression of B7H4 and cancer stemness proteins in 156 paraffin-embedded ESCC tissue samples using immunohistochemistry as well as in ESCC cell lines using Western blotting and immunofluorescence imaging. The correlation of B7H4 expression with clinicopathological parameters, cell cycle regulating genes, and PI3K/Akt/NF-κB signaling genes was investigated. The expression of B7H4 in ESCC tissue was correlated with the primary tumor (pT) stage, stromal activity, and the expression of CD68 and HIF-1α. However, B7H4 expression was negatively associated with CD8+ T cell infiltration in ESCC tissues. Moreover, B7H4 was found to be strongly linked to prognostic factors leading to poor clinical outcome. B7H4-expressing cancer cells also expressed known cancer stemness proteins (Sox9, LSD1, Oct4, and LGR5). Moreover, B7H4, Sox9, LSD1, Oct4, and LGR5 were highly expressed in more poorly differentiated ESCC cell lines. Notably, B7H4 expression was positively associated with the expression of cell cycle regulators such as cyclin D1, p27, and PI3K/Akt/NFκB signaling proteins. B7H4 could be a novel cancer stem cell marker for the prognostic evaluation of ESCC patients as well as a potential therapeutic target against ESCC.

Abstract
BACKGROUND A disintegrin and metalloprotease with thrombospondin motif (ADAMTS) enzymes play important roles in cell functions including adhesion, invasion, migration, and proliferation. ADAMTS-6 is a member of the ADAMTS family; reports of its relationship with esophageal squamous cell carcinoma (ESCC) progression are rare. It is unclear whether ADAMTS-6 could be an independent ESCC biomarker. METHODS ADAMTS-6 expression was detected by immunohistochemistry (IHC) in 171 paraffin-embedded ESCC specimens; relationships with patients' clinicopathological features and Twist-1 expression were analyzed by the Pearson Chi-square method, respectively. Overall survival (OS) and disease-free survival (DFS) were determined using the Kaplan-Meier method and compared using the long-rank test. RESULTS ADAMTS-6 was expressed mainly in the cytoplasm and nucleus; the expression was significantly higher in tumor tissues. Increased expression of ADAMTS-6 correlated with clinical stage (P = 0.009), pT stage (P = 0.042), lymph node metastasis (P = 0.014) and recurrence (P = 0.033). There were no significant correlations between ADAMTS-6 expression and other clinicopathological parameters including age, sex, tumor size, distant metastasis, differentiation, …chemotherapy, radiotherapy, CD68 expression and epithelial mesenchymal transition (EMT) status. Kaplan-Meier survival curves revealed that upregulated expression of ADAMTS-6 indicated short OS (P = 0.001) and DFS (P = 0.002). Multivariate analysis confirmed that high ADAMTS-6 expression was an independent factor for ESCC prognosis. ADAMTS-6 expression was significantly correlated with Twist-1 expression in ESCC cancer cells (P = 0.007) and stromal cells (P < 0.001). Patients with ESCC revealing expression of both ADAMTS-6 and Twist-1 exhibited significantly reduced OS and DFS rates than other patients. CONCLUSIONS High ADAMTS-6 expression is a useful marker of poor prognosis in patients with ESCC.

Abstract
Purpose: To investigate the therapeutic effect of glucosamine cyclohexyl ester on osteoarthritis (OA) in a rat model.Methods: Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot assays were used to analyze the effect of glucosamine cyclohexyl ester on changes in mRNA and protein expressions of matrix metalloproteinase and tissue inhibitor of metalloproteinases-1 in isolated rat chondrocytes, and in a rat model of OA. The rat model of OA was prepared by injecting monoiodoacetate to Sprague-Dawley rats via intra-articular route.Results: Treatment of the chondrocytes with glucosamine cyclohexyl ester for 48 h prevented interleukin-1 β (IL-1β)-mediated increases in mRNA and protein expressions in matrix metalloproteinases-1, -3 and -13, and also blocked IL-1β-induced decreases in mRNA and protein expressions of tissue inhibitor of metalloproteinase-1. Glucosamine cyclohexyl ester treatment also blocked the onset of morphological changes such as irregular surface, adhesion of tissues andpresence of osteophytes in the femoral condyle surface of the OA rats. Mankin score for control, OA and glucosamine cyclohexyl ester treatment groups were 0.98 ± 0.15, 8.35 ± 0.88 and 2.39 ± 0. 67 (p = 0.002), respectively. Treatment of OA rats with glucosamine cyclohexyl ester also inhibited increases in the activities of matrix metalloproteinases-1, -3 and -13, and decreases of tissue inhibitor of metalloproteinase-1 mRNA and protein expressions. Treatment of chondrocytes and OA rats with IL-1β caused no significant changes in the levels of H3K27 and H4K8.Conclusion: These results show that glucosamine cyclohexyl ester prevents OA by targeting the expressions of matrix metalloproteinases-1, -3 and -13 and tissue inhibitor of metalloproteinases-1.Keywords: Metalloproteinases, Interleukin, Mankin score, Osteoarthritis, Cartilage
