Abstract
PURPOSE The aim of the present study was to elucidate the functional role of hsa-miR-328-3p/STAT3 pathway in the effects of propofol on gastric cancer proliferation. METHODS Bioinformatics was used to analyze the molecular expression differences of hsa-miR-328-3p/STAT3 axis in stomach adenocarcinoma (n = 435) and normal samples (n = 41) from TCGA database. The expression of the above molecules in gastric cancer cells SGC-7901 and normal gastric mucosal cells GES-1 was verified via qPCR. The dual-luciferase assay was carried out to confirm the interaction between hsa-miR-328-3p and STAT3. Subsequently, the cell proliferation and the expression of the above molecules in SGC-7901 and GES-1 cells were evaluated after 10 μM propofol treatment. Finally, we analyzed whether propofol still inhibited the proliferation of gastric cancer by suppressing STAT3 pathway after hsa-miR-328-3p down-regulation. RESULTS Compared with normal samples, the expression of hsa-miR-328-3p was significantly down-regulated in stomach adenocarcinoma samples, while the expression of STAT3 and downstream target genes (MMP2, CCND1 and COX2) was up-regulated. The results were consistent with those in GES-1 and SGC-7901 cell lines. Meanwhile, we found that hsa-miR-328-3p can bind to the 3'-UTR of the potential target gene STAT3. Furthermore, propofol significantly inhibited the proliferation of gastric cancer cell line SGC-7901, where hsa-miR-328-3p was up-regulated and the expression of STAT3 and downstream proliferation-related target genes were down-regulated. However, the growth inhibition of propofol on SGC-7901 cell was significantly reversed after the inhibition of hsa-miR-328-3p. CONCLUSIONS To sum up, propofol suppressed the STAT3 pathway via up-regulating hsa-miR-328-3p to inhibit gastric cancer proliferation.

Abstract
Idiopathic non-cirrhotic portal hypertension is a rare group of clinical syndromes characterized by clinical manifestations of portal hypertension in the absence of histological manifestations of liver cirrhosis, and with the exclusion of known intrahepatic and extrahepatic causes of portal hypertension. Importantly, its etiology and pathogenesis are unclear, but it has been determined to be related to the development of intrahepatic vascular disease. It is currently believed that possible pathogenic mechanisms include immune disorders, chronic infections, drug-related poisoning or injury, microthrombosis, genetic abnormalities, etc. The most common clinical manifestations are esophagogastric varices and splenomegaly. Ascites and hepatic encephalopathy are the least common. Laboratory test demonstrates anemia, leukopenia, and thrombocytopenia due to hypersplenism, and normal or mild liver function abnormality. In addition, in the preclinical stage, despite the presence of abnormal portal vein during liver biopsy, no signs of portal hypertension can be detected in some patients. Therefore, the diagnosis is based on the diagnosis of exclusion and mandatory liver biopsy. The overall prognosis of idiopathic non-cirrhotic portal hypertension is better than that of patients with liver cirrhosis, but symptomatic treatment (controlling gastroesophageal varices bleeding and preventing thrombosis) is still the main treatment.

Abstract
Objective: To study the significance of induction chemotherapy and subsequent comprehensive therapy for overall survival rate (OS) and larynx dysfunction-free survival rate (LDFS) in patients with advanced hypopharyngeal carcinoma. Methods: Patients who met the inclusion criteria with the diagnoses of advanced hypopharyngeal carcinoma between 2011 and 2017 received 2 or 3 cycles of TPF regimen induction chemotherapy. Patients who attained complete response (CR) received radical chemotherapy. Patients who attained partial response (PR) and the reduction of tumor volume was more than 70% were defined as large PR and received concurrent chemoradiotherapy. When the tumor volume reduction of PR patients was less than 70%, they were defined as small PR. (CR+large PR) group was defined as effective group. Patients who did not reach CR and large PR were defined as uneffective group and underwent radical surgery and received adjuvant radiotherapy as appropriate after the surgery. The end points of the study were OS, progression-free survival (PFS) and LDFS. Chi-square (χ(2)) test was used for correlation analysis. Survival analysis was performed by the Kaplan-Meier method with a Log-rank test. Cox proportional hazards model was used for univariate and multivariate survival analysis. Results: A total of 260 patients were enrolled in the study. The follow-up period ranged from 5 to 83 months, with an average of 24.7 months. The 3-year and 5-year OS rate was 46.0% and 32.6%, respectively. The 3-year and 5-year PFS rate was 41.0% and 26.6%, respectively. The 3-year and 5-year LDFS rate was 37.9% and 24.8%, respectively. Poor outcome of induction chemotherapy, advanced N stage, strong positive Ki-67 immunohistochemistry (all P<0.001) were negative prognostic factors. The advanced clinical stage was positively related to the poor outcome of induction chemotherapy (P=0.015). There was no significant difference in OS and PFS between the large PR group and the small PR group (all P>0.005). Conclusion: TPF regimen induction chemotherapy and subsequent comprehensive therapy for patients with advanced hypopharyngeal carcinoma may improve the quality of life of patients, with high OS rate and LDFS rate.

Comparison of the Levels of Transforming Growth Factor-β1 in Tear Fluid in Patients with High Myopia after Transepithelial Photorefractive Keratectomy and Laser Subepithelial Keratomileusis (LASEK). Bull Exp Biol Med 2020; 170:79-83.

Abstract
We compared the level of transforming growth factor-β1 (TGF-β1) in the tear fluid of 20 patients with high myopia who underwent transepithelial photorefractive keratectomy (T-PRK) in one eye and laser subepithelial keratomileusis (LASEK) in the contralateral eye. Tear fluid samples were collected with scaled microcapillary tubes before (day 0) and on days 1, 3, and 5 after surgery. The release of TGF-β1 was determined by multiplying the concentration of TGF-β1 by capillary tear fluid flow. Corneal haze was also evaluated in 1, 3, and 6 months after surgeries. The median TGF-β1 release after T-PRK and LASEK differed significantly on days 1 and 3 (p<0.005) and on day 5 (p<0.05). The mean corneal haze score after T-PRK and LASEK also significantly differed in 1 month (p<0.005), but no significant differences in this parameter were revealed at later terms. Thus, the level of TGF-β1 in the tear fluid after T-PRK was lower than after LASEK, which can be the cause of less pronounced corneal haze in 1 month after surgery.

Abstract
Objective: To study the clinical pathological features of patients with relapsed diffuse large B-celllymphoma (DLBCL) and to provide evidence for early clinical screening of recurrent cases. Methods: The clinical and pathological data of the 20 patients, who had relapsed DLBCL (relapsed group) and were admitted to the First Affiliated Hospital of Nanjing Medical University from January 2015 to December 2019, were included. Meanwhile, other 34 patients with DLBCL who had achieved complete response (CR) for 36 months or more (CR group) were used as controls.Statistical methods were used to retrospectively analyze the differences in general conditions, clinical characteristics, lab resultsand pathological features between the two groups. Results: Clinically, there were 6 males and 14 females with a median age of 55.5 (33-85) years in the relapsed group and 14 males and 20 females with a median age of 53 (15-89) years in the CR group. The relapsed and CR groups had significant difference in Ann Arbor stage (P=0.001), International Prognostic Index score (P=0.006), primary lesions (P=0.003), extranodal involvement (P=0.002), and hepatitis B viral infection (P=0.046), β2-MG level (P=0.029), LDH level (P=0.005) and CRP level (P=0.006), while the age (P=0.732), gender (P=0.416), ECOG score (P=0.248), B symptoms (P=0.511), the presence of hypoalbuminemia (P=0.279), anemia (P=0.983) and A/G(P=0.416) showed no statistical difference.Pathologically, compared with the CR group, the relapsed group was mostly non-GCB type (85% vs. 59%,P=0.048), with a higher CD5 positive rate (25% vs.3%,P=0.014) and a lower bcl-6 positive rate (60% vs. 88%,P=0.017), while the expression of Ki-67, CD10, bcl-2, MUM1, CD20 and PAX5 was not different between the two groups. Conclusion: Most of the patients with relapsed DLBCL are non-GCB type. The patients with CD5 positivity, stage III-IV, International Prognostic Index score 3-5, nodal origin, often involving>1 extranodal organ, abnormally elevated LDH, CRP and β2-MG level, and HBV infection are more likely to relapse.

Abstract
Foot pad dermatitis (FPD) is a serious problem of the modern poultry industry, negatively affecting birds' welfare and health status, walking and feeding activity, growth performance, carcass quality, and economic performance of meat production. The gut microbiome in poultry with FPD has not been previously investigated. Therefore, we compared the cecal microbiomes of 8 breeding ducks with FPD to 8 control ducks (breeders with apparently healthy feet) by pyrosequencing the bacterial 16S ribosomal RNA gene. The results showed a significant β-diversity (P < 0.05) of cecal microbiota presented between healthy and FPD-affected breeder ducks. The plasma endotoxins, interleukin 1β (IL-1β), IL-17, IL-6, IL-10, and tumor necrosis factor-α concentration, and the abundance of class Clostridia in FPD-affected ducks was markedly higher (P < 0.05), however, the abundance of genus Prevotella, Lactobacillus, Lachnospiraceae UCG-008, and the Firmicutes to Bacteroidetes ratio in FPD-affected ducks was significantly lower (P < 0.05) when compared to healthy ducks. These findings suggest when duck breeders are affected with FPD, ducks show an increased inflammatory response and a difference of structure and composition of the cecal microbiome.

Abstract
Objective: To analyze the clinical value of capsule endoscopy (CE) in small intestinal diseases and to explore the correlation between the diagnosis and clinical characteristics. Methods: From June 2016 to April 2019, a total of 194 patients receiving CE were enrolled in the Department of Gastroenterology, Shanxi People's Hospital, including 68 patients with obscure gastrointestinal bleeding, 104 with chronic abdominal pain and 22 with diarrhea. Results: The detection rate of small intestinal lesions by CE was 53.6%(104/194), of which gastrointestinal bleeding was 66.2% (45/68), chronic abdominal pain was 53.8%(56/104), and diarrhea was 13.6%(3/22). The first three positive diagnostic criteria of CE for gastrointestinal bleeding were non-specific inflammation, small intestinal ulcer and vascular malformation. CE findings in patients with abdominal pain were non-specific inflammation, small intestinal ulcer and Crohn's disease; while the major endoscopic presentations in patients with diarrhea were small intestinal ulcer and non-specific inflammation. Logistic regression analysis suggested that the clinical manifestations and gender were correlated with positive diagnosis by CE (P<0.05), and the positive diagnostic rate of CE in female patients was significantly lower than that in male patients [31.6%(25/79) vs. 51.3%(59/115), P<0.05]. The diagnostic rates of CE in patients with gastrointestinal bleeding and chronic abdominal pain were similar [55.9%(38/68) vs. 41.4%(43/104)], which was significantly higher than those with diarrhea [9.1%(2/22), P<0.05]. Conclusions: Capsule endoscopy has a high detection rate for small intestinal diseases, which could be the first choice in patients with unexplained gastrointestinal bleeding. Male patients and gastrointestinal bleeding are predictors of positive findings by CE.

Abstract
Objective: To analyze the differentially expressed genes related to the chemosensitivity with the TPF regimen for hypopharyngeal squamous cell carcinoma and to measure potential functional targeting genes expressions. Methods: Twenty-nine patients with primary hypopharyngeal cancer who underwent induction chemotherapy with TPF from January 2013 to December 2017 in Beijing Tongren Hospital were enrolled for microarray analysis, including 28 males and 1 female, aged from 43 to 73 years old. Among them, 16 patients were sensitive to chemotherapy while 13 patients were non-sensitive. Illumina Human HT-12 Bead Chip was applied to analyze the gene expressions and online bioinformatics analysis was used to analyze the differentially expressed genes. Reverse transcription and quantitative real-time PCR (RT-qPCR) was used to measure the mRNA expression of potential functional genes of TPF induction chemotherapy in 43 samples, 29 from original patients and 14 from additional patients. Graphpad prism 7.0 software was used for statistical analysis. Results: A total of 1 381 significantly differentially expressed genes were screened out. By GO analysis, up-regulated genes included sequestering in extracellular matrix, chemokine receptor binding and potassium channel regulator activity; down-regulated genes included regulation of angiogenesis, calcium ion binding and natural killer cell activation involved in immune response. With KEGG database analysis, down-regulated pathways included ECM-receptor interaction and peroxisome and up-regulated pathways included Glutathione metabolism and PPAR signaling pathway. The expressions of CD44 and IL-6R were significantly different and appeared biologically significant. CD44 was significantly upregulated in insensitive tissues (0.54±0.06) compared with sensitive tissues (0.33±0.04)(P<0.01). IL-6R was significantly downregulated in insensitive tissues (0.44±0.03) compared with sensitive tissues. (0.68±0.03) (P<0.01). Conclusion: CD44 and IL-6R may be potentially functional genes of TPF induction chemotherapy in hypopharyngeal squamous cell carcinoma.

Abstract
Objective: To understand the etiology of hepatopathy of unknown etiology in patients undergoing liver biopsy. Methods: Demographic data and pathological examination reports of patients with hepatopathy of unknown etiology who underwent liver biopsy examination at outpatient and inpatient of the Second Hospital of Nanjing between January 2017 and June 2018 were retrospectively collected. All liver histopathological sections combined with clinical and pathological features based on liver biopsy examinations were diagnosed by a reputed clinician and a pathologist. Results: A total of 470 cases with hepatopathy of unknown etiology who underwent liver biopsy were enrolled. Of these, 425 cases (90.4%) had a definite diagnosed disease after comprehensive analysis of pathological and clinical data. The diagnosis of hepatopathy of unknown etiology included 11 diseases: 90 cases with autoimmune hepatitis had autoimmune liver disease (19.1%), 38 cases had primary biliary cholangitis (8.1%), 43 cases with overlap syndrome of autoimmune hepatitis had primary biliary cholangitis (9.1%), 118 cases had drug-induced liver injury (25.1%), 75 cases had nonalcoholic fatty liver disease (NAFLD) (16.0%), 12 cases had alcoholic liver disease (2.6 cases) %), 15 cases (3.2%) had vascular liver disease, 7 cases (1.5%) had hereditary metabolic liver disease, 5 cases (1.1%) had other systemic diseases, 16 cases (3.4%) had more than two kinds of liver diseases, and 6 cases (1.3%) had others rare liver diseases. Conclusion: Over 90% cause of the hepatopathy of unknown etiology in the long run can be determined, and the main causes are autoimmune liver disease, drug-induced liver injury, and nonalcoholic fatty liver disease, which needs multidisciplinary cooperation to diagnose, and clinicians need to master the basic and clinical knowledge of liver diseases as well as liver pathology, hepatobiliary imaging, and genetics.

Abstract
Objective: To compare and analyze patient's general condition, changes in laboratory parameters, and the spectrum of UGT1A1 mutations in patients with inherited non-hemolytic unconjugated hyperbilirubinemia. Methods: A retrospective study was conducted at Nanjing Second Hospital from January 2015 to July 2018 and patients' demographic characteristics, liver function test, and UGT1A1 gene were analyzed. The categorical variable data were compared by χ (2) test. The normal distribution continuous variable data were compared by t-test and the non-normal distribution continuous variable data were compared using Mann-Whitney U test. Results: Of the 51 patients with inherited non-hemolytic unconjugated hyperbilirubinemia, 44 (86.3%) were Gilbert's syndrome (GS) and seven (13.7%) were Crigler-Najjar syndrome type II (CNS- II). The male to female ratio was 2.9:1 and the average age was 36.11 ± 13.17 years. Six variant types were detected: C. -40_-39insTA, C. -3279T > G, c.211G > A (p.G71R), c.686C > A (p.P229Q), c.1091C > T (p.P364L), c.1456T > G (P.Y486D). Among them, c.211G > A accounted for 58.82% (30/51), c.-40_-39insTA accounted for 27.5% (14/51), and c.1456T > G accounted for 25.5% (13/51). The total bilirubin(TB) and unconjugated bilirubin (UCB) in CNS-II patients were significantly higher than GS patients[155.91 (130 ~ 207) vs. 38.25(29 ~ 52.15) μmol/L, U = 0, P < 0.01; 144.13 (120.8 ~ 197) vs. 30.00 (21.7 ~ 46.75) μmol/L, U = 0.00, P < 0.01, respectively]. Exon mutations of c.1091C > T and c.1456T > G were statistically significant(P < 0.01).There were no differences in age, TB, UCB, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) between the c.211G > A homozygous variants and heterozygous variants (P > 0.05). Conclusion: The common pathogenic mutations of UGT1A1 gene were c.211G > A, c.-40_-39insTA, c.1456T > G. c.211G > A. The mutation has little effect on the level of total bilirubin, but c.1091C > T, c.1456T > G mutations has great influence on the level of total bilirubin.

Abstract
Thyroid (T3) hormone beta1 (TR) and 9-cis retinoic acid (9c-RA) retinoid X receptors (RXR) can form heterodimer complexes that bind to hormone response elements (HREs) in target genes to either activate or repress transcription. However, the action of each cognate ligand and the accessory cellular factors that can differentially regulate the transcriptional responses of a heterodimer-DNA complex are not well understood. Studies in most mammalian cell lines have demonstrated that 9c-RA cannot bind or transactivate TR/RXR-T3 response element (TRE) complexes. In contrast, when identical heterodimer complexes were coexpressed in the yeast (Saccharomyces cerevisiae) with single copy typical TREs [i.e., DR+4 (direct repeat), F2 (everted repeat), or PAL (inverted repeat) DNA response elements] we observed that i) unliganded TRbeta1 homodimers had constitutive action on F2 and PAL but not DR4 TREs; ii) TRbeta1 homodimer responsivity to T3 ligand was relatively weak (less than twofold) and was only demonstrable on F2 but not PAL or DR4-TREs, whereas TRbeta1 heterodimers responded to T3 when RXRgamma but not RXR alpha was the heterodimeric partner; iii) RXR responsivity to 9c-RA (three- to sixfold) could be demonstrated only on palindromic TREs that could be enhanced by TRbeta1 on all TREs; iv) T3 + 9c-RA ligands increased (additively or synergistically) transactivation when RXRgamma but not alpha heterodimerized with TRbeta1 on both typical as well as atypical (DR1, DR3, DR5, and F2M) TREs. Substitutions for wild-type TRbeta1 of C-terminus mutants deficient in dimerization with RXRs abrogated the anticipated single and dual cognate ligand-induced effects on TRbeta1/RXRgamma transactivation of DR4 TREs, whereas mutants with preserved dimerization function but impaired T3 transactivation regions could maintain an enhanced 9c-RA response but were devoid of the anticipated T3 and dual (T3 + 9c-RA) cognate ligand-induced effects. Thus, the ligand-inducible response of TR and RXR homodimers expressed in yeast are relatively weak but can be further enhanced by TRbeta1 cross-talk with specific RXR subtypes in the presence of both cognate ligands.

Abstract
Sparganosis mansoni is a parasitic disease caused by the larva of Spirometra mansoni, which occurs worldwide, especially in Asian countries. In recent years, there have been cases of sparganosis reported in Guizhou province in southwest China. In this report, a case of sparganosis mansoni with a painful mass in perineal region is presented. The patient is a 49-year-old Chinese woman, she did not have a history of eating raw frogs or snakes. But she drank unboiled water from rivers and streams. Physical examination showed her vital signs were stable and blood routine examination was also regular. After surgery to remove the mass, a worm was removed from the foreign matter, which measured about 10 cm in length and 2 mm in diameter, that was identified as S. mansoni. One week after the operation, her symptoms changed significantly. To our knowledge, this is the first case of perineal sparganosis mansoni in Guizhou. Surgical removal is effective for the treatment of perineal sparganosis, followed by a course of therapy.

Abstract
OBJECTIVE Vacuolar ATPase (V-ATPase) was found within the membranes and internal organelles of a vast array of eukaryotic cells, and was related to various kinds of highly metastatic tumors. LASS2/TMSG1 gene was a novel tumor metastasis suppressor gene cloned from human prostate cancer cell line PC-3M in 1999 by our laboratory. It was found out that protein encoded by LASS2/TMSG1 could interact with the c subunit of V-ATPase (ATP6V0C). In this study, To use RNA interference to suppress the expression of ATP6V0C and try to further investigate the molecular mechanism of ATP6V0C in tumor metastasis and its relationship with LASS2/TMSG1 gene. METHODS AND RESULTS The expression level of ATP6V0C mRNA and protein in high metastatic potential prostate cancer cell lines (PC-3M-1E8 and PC-3M) was significantly higher than that in low metastatic potential prostate cancer cell lines (PC-3M-2B4 and PC-3), the expression level in PC-3M-1E8 being the highest. Follow-up tests selected PC-3M-1E8 cells for gene silencing. The expression and secretion of MMP-2 and the expression of MMP-9 in ATP6V0C siRNA transfected PC-3M-1E8 cells displayed no obvious change, but the activity of secreted MMP-9 was abated noticeably compared with the controls (P<0.05). Extracellular hydrogen ion concentration and V-ATPase activity in interference group were both reduced significantly compared with the controls (P<0.05). The migration and invasion capacity of ATP6V0C siRNA interfered cells in vitro were diminished significantly compared with the controls (P<0.05). Furthermore, a dramatic reduction of LASS2/TMSG1 mRNA and protein level after transfection of siRNA in PC-3M-1E8 cells was discovered (P<0.05). Confocal immunofluorescence showed a vast co-localization of ATP6V0C protein and LASS2/TMSG1 protein in plasma and membrane. The co-localization signals of control group were much stronger than those of interference group. CONCLUSION Specific siRNA silencing of ATP6V0C gene inhi-bits the invasion of human prostate cancer cells in vitro by mechanism of inhibiting V-ATPase activity and then reducing the extracellular hydrogen ion concentration, inhibiting MMP-9 activation and affecting ECM degradation and reconstruction. Meanwhile, ATP6V0C and LASS2/TMSG1 have interaction and it is likely that ATP6V0C functions as a feedback regulator of LASS2/TMSG1.

Abstract
Objective: The objective was to assess the relationship between early response and later response to antipsychotics, and the relationship between antipsychotics and early response. Methods: Data were retrospectively analyzed from patients with schizophrenia and they were hospitalized in the Second Affiliated Hospital of Xinxiang Medical College from May, 2013 to September, 2015.The patients were divided into theearly response group (PANSS total score improvement ≥20% at week 2) and early nonresponse group.General information, the use of drug and the Positive and Negative Syndrome Scale (PANSS) on before and 2, 4, 6 weeks after treatment were compared between the two groups.The relation between early response and late response and the effect of drug selection on early response were analyzed by correlation analysis and regression analysis. Results: Relative to early nonresponders, early responders were significantly more likely to have lower PANSS scores (total scores on 2, 4, 6 weeks after treatment 66.2±11.8 vs 84.5±10.9, 55.9±13.2 vs 70.9±13.7, 48.9±13.1 vs 60.6±14.9, all P<0.05) and higher PANSS scores improvement at 2, 4, 6 weeks after treatment (total scores improvement on 2, 4, 6 weeks after treatment (37±14)% vs (9±7)%, (56±19)% vs (32±18)%, (68±20)% vs (49±21)%, all P<0.05). The correlation coefficient between PANSS total score improvement at week 2 and at week 4, 6 were 0.730 and 0.541, respectively (all P<0.05). Olanzapine had more PANSS total score improvement than aripiprazole, quetiapine and ziprasidone (2 weeks after treatment (29±19)% vs (19±16)%, (18±15)%, (17±15)%, 4 weeks after treatment (51±21)% vs (37±25)%, (39±18)%, (37±22)%, all P<0.05). The protective factor for early response was olanzapine (P<0.05). Conclusions: Early responders are associated with faster and greater improvement in symptoms, the type of antipsychotic has impacts on early response, early non-responders can benefit from adjustment of treatment.

Abstract
BACKGROUND Tibiotalocalcaneal arthrodesis is most common and effective surgical treatment for severe hindfoot pathology, but the fusion rate is often lower than the ordinary tibiotalar arthrodesis because of the more serious joint disease associated with obvious deformity and osteoporosis. Recent literature describe tibiotalocalcaneal arthrodesis with reverse PHILOS plate with good clinical outcome result, though some patients non-union, due to eccentric force of the plate may be hidden. The purpose of this study was to evaluate clinical outcome of the lateral approach for tibiotalocalcaneal (TTC) arthrodesis with reverse PHILOS Plate and medial cannulated screw. METHODS Between Jun, 2013 to April, 2015 12 patient with hindfoot pathology had TTC arthrodesis with a reverse PHILOS plate with medial cannulated screw through a lateral approach with resection of the distal fibula and bone graft. Perioperatively observe for wound and neurovascular status. Patients were follow-up from post-operative 1, 3, 6 and12 months, to observation of wound healing, ankle pain, subtalar Joint Fusion, internal fixation and ankle function. Ankle function were scored according to the American Orthopaedic Foot and Ankle Society(AOFAS) Ankle-Hindfoot Scale system. RESULTS Twelve ankle fusion all patient follow-up, with mean time to surgery 18.6 months (12-36 month). No cases infection and issue necrosis; one patient complaint of lateral foot numbness we observe and follow-up was spontaneously recovery after 3 months. After 3 months of operation, no obvious pain of ankle joint and internal fixations loose were found. Almost fusion and good axial alignment of TTC joint also were found by X-ray and CT examination. After final fellow-up of each case, no case complain of pain of ankle joint, good fusion and axial alignment of TTC joint were also all found through Terminology. The mean American Orthopaedic Foot and Ankle society (AOFAS) score average was 77.5. CONCLUSION TTC arthrodesis with reverse PHILOS Plate and medial cannulated screw have advantages of clear incision, effective bone orthopaedic and graft fully secure, stable internal fixation, high fusion rate and less complications, can effectively correct deformities, alleviate hindfoot pain and improve function, and is an effective method of treatment of after severe hindfoot disease. TRIAL REGISTRATION This trial is registered on ClinicalTrials.gov with reference number: ID: NCT02977910 . Registered 26 Nov 2016, retrospectively registered.

Abstract
We used the conventional and methylation-sensitive randomly amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analyses to assess genome-wide changes and explore the relationships between genetic and epigenetic variations among individuals of a newly synthesized allohexaploid wheat line whose genomic constitution is identical to that of the natural common wheat, compared with its parent plants and a natural counterpart named Chinese Spring. We found rapid, extensive, and predominantly consistent non-Mendelian changes in the form of genetic and DNA methylation variations in the allohexaploid individuals. Specifically, at least 30-40% of the epigenetic component was truly independent of genetic changes, which answered a critical question, i.e. its autonomy in relation to the genetic context. Striking correlations were detected between genetic and epigenetic changes. Interestingly, as previously reported, the paternally donated nuclear genomes showed more genetic changes than the maternally donated ones; the loss of paternal bands was significantly correlated with the hypomethylation of CG or CHG sequences, suggesting an unknown link between genetic instability and hypomethylation. Sequence analysis indicated that most variations occurred in the cellular genes and sequences related to transposable elements. Based on these findings, the possible mechanisms and effects of the genomic changes in allopolyploid speciation and evolution were discussed.

Abstract
Observational study is a method most commonly used in the etiology study of epidemiology, but confounders, always distort the true causality between exposure and outcome when local inferencing. In order to eliminate these confounding, the determining of variables which need to be adjusted become a key issue. Directed acyclic graph(DAG)could visualize complex causality, provide a simple and intuitive way to identify the confounding, and convert it into the finding of the minimal sufficient adjustment for the control of confounding. On the one hand, directed acyclic graph can choose less variables, which increase statistical efficiency of the analysis. On the other hand, it could help avoiding variables that is not measured or with missing values. In a word, the directed acyclic graph could facilitate the reveal of the real causality effectively.
