Abstract
Healing of dense regular connective tissue, due to a high fiber-to-cell ratio and low metabolic activity and regeneration potential, frequently requires surgical implantation or reconstruction with high risk of reinjury. An alternative to synthetic implants is using bioscaffolds obtained through decellularization, a process where the aim is to extract cells from the tissue while preserving the tissue-specific native molecular structure of the ECM. Proteins, lipids, nucleic acids and other various extracellular molecules are largely involved in differentiation, proliferation, vascularization and collagen fibers deposit, making them the crucial processes in tissue regeneration. Because of the multiple possible forms of cell extraction, there is no standardized protocol in dense regular connective tissue (DRCT). Many modifications of the structure, shape and composition of the bioscaffold have also been described to improve the therapeutic result following the implantation of decellularized connective tissue. The available data provide a valuable source of crucial information. However, the wide spectrum of decellularization makes it important to understand the key aspects of bioscaffolds relative to their potential use in tissue regeneration.

A Systematic Review on the Role of Matrix Metalloproteinases in the Pathogenesis of Inguinal Hernias. Biomolecules 2023; 13:1123. [PMID: 37509159 PMCID: PMC10377325 DOI: 10.3390/biom13071123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/06/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023] Open
Abstract
The recurrence rate in patients who undergo surgery for abdominal wall hernias (AWHs) is high. AWHs have been hypothesized to be a disease of the extracellular matrix, which is supported by evidence showing a high incidence of AWHs in patients with connective tissue disorders. This study aimed to investigate the most recent literature studies describing the levels of several matrix metalloproteinases (MMPs) in the blood and fascia, with the objective of better clarifying the pathogenetic role of matrix metalloproteinases (MMPs) and their inhibitors in inguinal hernias (IHs). A systematic literature search was conducted using the PubMed, Scopus, and Web of Science electronic databases to identify eligible studies. The identified studies were included in the analysis, and a qualitative synthesis of the results is provided to describe the most recent findings. Seventeen studies were included. An association between MMP-2 and direct IHs has also been demonstrated. MMP-1, MMP-2, MMP-9, MMP-12, and MMP-13 levels were increased in both the serum and fascia of patients with IHs. The analysis of inhibitors showed an increase in tissue inhibitors of metalloproteinases (TIMPs), specifically TIMP-1 in IHs, particularly in direct hernias, and a reduction in TIMP-2 in the biopsy samples of the transversalis fascia. In contrast, a reduction in TIMP-1 and an increase in TIMP-2 levels have been reported only in the serum of patients with IHs. Metalloproteinases play a crucial role in the pathogenesis of IHs. The analysis of other molecules, such as TIMPs or their correlation with specific genes, is enhancing our understanding of the pathophysiology of IHs. However, more prospective studies, including comprehensive clinical and laboratory data collection, are required to confirm the relationship between the studied biomarkers and the risk of IHs.

Abstract
A hyalinizing trabecular tumor (HTT) of the thyroid gland is a very rare type of tumor. It is usually diagnosed incidentally during the examination for thyroid gland diseases that need thyroidectomy. Here we report a case of HTT in a 60-year-old male patient who presented with anterior neck swelling and underwent total thyroidectomy for a Bethesda category V nodule. The final histologic diagnosis of the left lobe was consistent with a hyalinized trabecular adenoma of the thyroid gland, or paraganglioma-like adenoma. We discuss the clinical picture and diagnostic approach, including the role of fine needle aspiration biopsy, and the pathologic features of HTT, with particular reference to the possible differential diagnosis.

Abstract
Background Ventral hernias commonly affect patients after major abdominal surgery. To reduce postoperative pain, the effects of the transversus abdominis plane (TAP) block, epidural analgesia and medication-only protocol have been investigated. The primary outcome was the cumulative dosage of opioids (morphine milligram equivalents MME), of acetaminophen and diclofenac for postoperative pain control on postoperative day (POD) 0, 1, and 2. Secondary outcomes were length of stay (LOS) and the pain scale rating using the numeric rating scale (NRS) on POD 0, 1, and 2. Methods The data were retrospectively extracted from the charts of the patients admitted for a surgical operation for OVHR from January 2015 to December 2019. Results Patients receiving medication-only analgesia had longer LOS (mean 6.1 days; p < 0.00001). Cumulative opioid consumption was significantly lower at 24 and 48 h after surgery in the TAP block group than in the other groups (mean MME 1.9 mg and 0.7 mg, respectively; p < 0.05). The cumulative consumption of diclofenac was significantly lower in the TAP block group than in the others (44.1 mg; p ≤ 0.00001 on POD 1; 4.4 mg; p = 0.03 on POD 2). TAP block is more effective in pain control in POD 0 (mean NRS 5.4; p < 0.00001), POD 1 (mean NRS 6.1; p = 0.006), and POD 2 (mean NRS 4.9; p = 0.001) if it is performed after adopting the retromuscular technique. Conclusions The comparison between the medication-only technique, epidural, and TAP block demonstrated the superiority of the last one for the aims considered in this study.

Abstract
Matrix metalloproteinases (MMPs) are associated with the alteration of extracellular matrix. The purpose of this study was to investigate how the levels of matrix metalloproteinases and their inhibitors - TIMPs are influenced by the presence of inguinal hernia as well as by its surgical treatment. The studied group consisted of 25 patients with inguinal hernia and 21 healthy controls for comparison. Two blood samples - before and after the treatment were collected from patients. Serum concentrations of MMPs and TIMPs were analysed by multiplex immunoassays. There was a difference in circulating levels of MMPs in patients before the surgery compared to healthy controls - the concentrations of MMP-2 and MMP-9 were significantly lower (p=0.026, p=0.018, respectively). After the surgery, the levels of MMPs, especially MMP-2 (p<0.0001), were significantly decreased in patients compared to the preoperative values, apart from MMP-9. On the contrary, MMP-9 showed significant increase after the surgery (p<0.0001). Circulation levels of TIMP-2 in patients were significantly decreased in comparison with controls (p=0.004), whereas levels of TIMP-1 were similar to controls. Both tested metalloproteinase inhibitors showed a significant decrease in detected levels (TIMP-1 p=0.0004; TIMP-2 p<0.0001) after the procedure compared to the preoperative values. The levels of MMPs, especially MMP-2 and MMP-9, and their inhibitors TIMP-1 and TIMP-2 are involved by the presence of inguinal hernia as well as are influenced by the surgery.

Abstract
BACKGROUND Collagen metabolism, controlled by matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs), might be related to inguinal hernia formation. It was reported that the incidence of inguinal hernia and the recurrence rate after inguinal hernia repair were higher in the elderly. The objective of the research was to assess the amounts of MMP-2 and TIMP-2 in patients at different ages in order to examine the relationship between age and inguinal hernia occurrence. METHODS The research included 40 primary inguinal hernia male patients, and four groups were created: 50-59 years old (A group); 60-69 years old (B group); 70-79 years old (C group); 80-89 years old (D group). We got the samples from anterior rectus sheath fascia. Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) and immunohistochemistry were applied to estimate the levels of MMP-2 and TIMP-2. RESULTS The MMP-2 amounts in C and D group were statistically higher than control group (P < 0.05), and the TIMP-2 levels in C and D group were statistically lower than control group (P < 0.05). We found a positive correlation between age and expression levels of MMP-2 (r = 0.537, P < 0.001; r = 0.569, P < 0.001) and a negative correlation between age and TIMP-2 in inguinal hernia patients (r = - 0.759, P < 0.001; r = - 0.759, P < 0.001). CONCLUSIONS Increased MMP-2 and reduced TIMP-2 may have some relationships with higher inguinal hernia incidence of the elderly.

Abstract
In cardiovascular disorders, the myocardium may be subjected to the breakdown and remodeling of collagen by metalloproteinase-9 (MMP-9). We hypothesized that the serum MMP-9 concentration may be elevated in pediatric patients with rheumatic heart disease (RHD) and heart failure (HF), and its level can be correlated with the HF severity. Thus, in the present study, we aimed to evaluate the sensitivity and accuracy of MMP-9 to predict HF in children with RHD and to determine its effectiveness as an indicator of the degree of HF. This study included 98 consecutive children admitted to the Department of Pediatrics, Zagazig University Hospital, Al Sharqia Governorate, Egypt with newly diagnosed RHD. Their ages ranged from 8.5 to 16 years. Fifty-eight children had RHD without HF while 40 children were complicated with HF which was diagnosed clinically and by echocardiography. A total of 44 healthy children were enrolled as a control group. MMP-9 serum levels were estimated by enzyme-linked immunosorbent assay. The serum MMP-9 concentration was higher in the RHD without HF and RHD with HF groups than this level noted in the control (P<0.001). MMP-9 was a significant predictor of HF; area under the curve (AUC)=0.85 [95% confidence interval (CI), 0.76-0.94]. At the level of 386.9 ng/ml, MMP-9 detected HF with a sensitivity 95% (95% CI, 83.08-99.39), specificity 74.14% (95% CI, 60.96-84.74), positive predictive value 71.70% (95% CI, 61.96-79.75), negative predictive value 95.56% (95% CI, 84.67-98.82) and accuracy 82.65% (95% CI, 73.69-89.56). In addition, MMP-9 showed a significant negative correlation with ejection fraction and fractional shortening (P=0.01 and P=0.02, respectively). In conclusion; MMP-9 may be an independent sensitive marker with which to detect HF in children with RHD and it can predict the prognoses of these patients as it correlates with the severity of HF. Further studies considering MMP-9 in the detection of 'silent' RHD in school aged children and asymptomatic HF in children with known RHD especially in rural areas, are highly recommended.

Abstract
BACKGROUND The development of inguinal hernia might be related with collagen metabolism, which was regulated by matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). The aim of this study was to evaluate the mRNA and protein expression levels of MMP-2 and TIMP-2 in anterior rectus sheath fascia to investigate the function of them in inguinal hernia formation. METHODS The study enrolled 48 primary inguinal hernia patients: 32 participants had indirect inguinal hernia and 16 patients suffered direct inguinal hernia. Specimens were taken from the anterior rectus sheath fascia. The amounts of MMP-2 mRNA and TIMP-2 mRNA were evaluated by real-time fluorescence quantitative polymerase chain reaction (RT-PCR), and immunohistochemistry was performed to assess the protein expression of them. RESULTS The mRNA and protein expression levels of MMP-2 in direct group were significantly higher than those of control group (P < 0.05) and indirect group (P < 0.05), while the expression levels of TIMP-2 in direct group were significantly lower than those of control group (P < 0.05) and indirect group (P < 0.05). The ratio of MMP-2 mRNA/TIMP-2 mRNA in direct group was significantly higher than that of control group (P < 0.05) and indirect group (P < 0.05), and the ratio of indirect group was significantly higher than that of control group (P < 0.05). According to receiver operating characteristic (ROC) curve, MMP-2/TIMP-2 can diagnose direct hernia from controls with area under the curve (AUC) of 0.950 and indirect hernia with AUC of 0.730 effectively. CONCLUSIONS Elevated level of MMP-2 and decreased level of TIMP-2 may play a role in direct inguinal hernia development. The ratio of MMP-2/TIMP-2 may be useful in identification of direct hernia.

Abstract
BACKGROUND Surgical techniques for inguinal hernia repair have evolved rapidly from open methods to conventional laparoscopic totally extra-peritoneal (CTEP) and recently single-port TEP (STEP). As there is currently no randomized controlled trial (RCT) reporting long-term patient-reported outcomes between CTEP and STEP, we reviewed patients who were randomized to CTEP or STEP 5 years after surgery. METHODS Telephone interviews were administered to patients with primary unilateral inguinal hernia recruited for the RCT comparing CTEP and STEP in 2011. The modified Body Image Questionnaire was used to measure long-term patient-reported outcomes. RESULTS Forty-two out of forty-nine of the STEP group and forty-one out of fifty of the CTEP group responded to phone interviews. Median follow-up time, demographic data and clinical outcomes were comparable between both groups. The Body Image Score (5-20: 5-least dissatisfied, 20-most dissatisfied; BIS score ± SD, STEP vs. CTEP, 5.33 ± 0.90 vs. 7.17 ± 1.87, p < 0.001) and Cosmetic Score (2-20: 2-least satisfied, 20-most satisfied; CS score ± SD, STEP vs. CTEP, 19.05 ± 1.31 vs. 15.87 ± 1.57, p < 0.001) were superior in the STEP group. Similarly, self-reported scar perception (1-cannot be seen, 2-can barely be seen, 3-visible; scar perception score ± SD, STEP vs. CTEP, 1.29 ± 0.51 vs. 2.55 ± 0.64, p < 0.001) and overall experience score (1-least satisfied, 10-most satisfied; overall satisfaction score ± SD, STEP vs. CTEP, 9.57 ± 0.67 vs. 8.22 ± 0.94, p < 0.001) were superior in the STEP group. CONCLUSION Patients who underwent STEP reported superior cosmetic and satisfaction scores and comparable surgical outcomes 5 years after surgery compared to the CTEP group. STEP should be strongly considered in patients who are concerned about long-term cosmetic outcomes and should be offered if surgical expertise is available. Trial registration NCT02302937.

Abstract
Purpose: To investigate whether plasma and connective tissue matrix metalloproteinases (MMP) and their inhibitors (TIMP) may predict late high-pressure endoleak after endovascular aneurysm repair (EVAR). Materials and Methods: Samples of inguinal fascia and blood were collected in 72 consecutive patients (mean age 73.1 years; 68 men) undergoing primary EVAR with the Endurant stent-graft. Baseline plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 and baseline MMP-2 and MMP-9 activity estimated using gelatin zymography (GZ) were compared between patients who developed late endoleak in follow-up and those who did not. Subgroup analyses were performed between patients with (n=18) and without inguinal hernias and between patients with moderate-diameter (50–59 mm; n=45) or large-diameter (≥60 mm; n=27) abdominal aortic aneurysms (AAA) at primary EVAR. Results: The mean follow-up period was 63.1 months (range 7.5–91.5), during which time 13 (18.1%) patients developed type I (6 Ia and 5 Ib) or 2 type III endoleaks. Only GZ-analyzed proMMP-9 concentrations were higher in the endoleak group than in patients without endoleak (mean difference 8.44, 95% CI −19.653 to −1.087, p=0.03). The patients with primary inguinal hernia at presentation had significantly higher tissue TIMP-2 values (0.8±0.7 vs 0.5±0.4, p=0.018) but lower plasma total (pro- + active) MMP-9 values (11.9±7.8 vs 16.2±7.4, p=0.042) than patients without hernias at the time of EVAR. Patients with AAAs ≥60 mm had significantly higher mean tissue homogenate levels of total (pro- + active) MMP-9 (p=0.025) and total (pro- + active) MMP-2 (p=0.049) as well as higher proMMP-9 (p=0.018) and total (pro- + active) MMP-9 (p=0.021) levels based on GZ compared to patients with moderate-diameter AAAs. Regression analysis revealed a significant association between total (pro- + active) MMP-9 plasma samples and the presence of hernia (OR 0.899, 95% CI 0.817 to 0.989, p=0.029) and between GZ-analyzed proMMP-9 and late endoleak (OR 1.055, 95% CI 1.007 to 1.106, p=0.025). GZ-analyzed proMMP-9 and active MMP-9 were strong predictors of late endoleak in patients with hernia (p=0.012 and p=0.044, respectively) and in patients with AAAs ≥60 mm (p=0.018 and p=0.041 respectively). Conclusion: Inguinal fascial tissue proMMP-9 significantly predicted late endoleak. ProMMP-9 and active MMP-9 biomarkers are significantly associated with late endoleak in hernia patients and in patients with AAAs ≥60 mm. Considering the clinical association between hernia and AAA and the fact that the AAA wall connective tissue environment remains exposed to systemic circulation after EVAR, inguinal fascia extracellular matrix dysregulation and altered MMP activity may reflect similar changes in AAA biology, leading to complications such as endoleak.

Abstract
The extracellular matrix (ECM) is the main constituent of connective tissue with structural and regulatory functions, stimulating cell differentiation and proliferation. Moreover, ECM is a dynamic structure in the constant remodeling process, which is controlled by a balance between metalloproteinases (MMPs) and their inhibitors (TIMPs). Photobiomodulation (PBM) is widely described in the literature and applied in clinical practices, although its effects on ECM have not yet been elucidated. Therefore, it was evaluated if PBM could alter ECM components, such as MMP-2, -9, -13, and TIMP-2 from mice talocrural joints. Mice were divided into 3 groups (n = 6): control, PBM 3 J cm-2, and PBM 30 J cm-2. A low-level laser (830 nm, 10 mW, 0.05 irradiated area, energy densities 3 J cm-2 and 30 J cm-2, the irradiation time of 15 and 150 s, respectively, continuous wave) was applied on the joint for 4 consecutive days. mRNA levels of metalloproteinases genes (MMP-2, MMP-9, and MMP-13), their regulator (TIMP-2), and protein expressions of MMP-13 and TIMP-2 were quantified. PBM can alter only mRNA relative levels of MMP-2 at 30 J cm-2 (p < 0.05), while MMP-9, MMP-13, and TIMP-2 mRNA relative levels did not demonstrate statistical differences for any of the groups (p > 0.05). Regarding protein expressions, MMP-13 demonstrated positive-labeled cells, only in articular cartilage, although the cell quantification did not demonstrate statistical differences when compared with the control group (p > 0.05). TIMP-2 did not present positive-labeled cells for any tissues evaluated. Our results indicate that PBM can alter MMP-2 mRNA relative level but cannot alter MMP-9, MMP-13, and TIMP mRNA relative levels. Moreover, both MMP-13 and TIMP-2 proteins were also unaltered after PBM.

Abstract
Fibromatosis is a rare type of tumor derived from the mesenchymal tissue. This is a benign tumor with infiltrating growth but may invade locally and recur following excision. As one type of fibromatosis, mesenteric fibromatosis (MF) accounts for a mere 8% of cases. Although studies have revealed that the etiology of MF is related to trauma, surgery, hormones, and heredity, the specific etiology of fibromatosis remains unclear. With such low incidence, MF has been rarely reported and tends to be misdiagnosed due to insufficient recognition. In this paper, we describe the cases of two patients with MF who were misdiagnosed with lymph node metastasis and who had previously undergone successful laparoscopic right hemicolectomy. We provide this information in order to broaden the clinical understanding of MF.

Abstract
Surgical meshes are effective and frequently used to reinforce soft tissues. Fibrin glue (FG) has been widely used for mesh fixation and is also considered an optimal vehicle for stem cell delivery. The aim of this preclinical study was to evaluate the therapeutic effect of MSCs and their exosomes combined with FG for the treatment of incisional hernia. A murine incisional hernia model was used to implant surgical meshes and different treatments with FG, MSCs and exo-MSCs were applied. The implanted meshes were evaluated at day 7 by anatomopathology, cellular analysis of infiltrating leukocytes and gene expression analysis of TH1/TH2 cytokines, MMPs, TIMPs and collagens. Our results demonstrated a significant increase of anti-inflammatory M2 macrophages and TH2 cytokines when MSCs or exo-MSCs were used. Moreover, the analysis of MMPs, TIMPs and collagen exerted significant differences in the extracellular matrix and in the remodeling process. Our in vivo study suggests that the fixation of surgical meshes with FG and MSCs or exo-MSCs will have a beneficial effect for the treatment of incisional hernia in terms of improved outcomes of damaged tissue, and especially, in the modulation of inflammatory responses towards a less aggressive and pro-regenerative profile. STATEMENT OF SIGNIFICANCE The implantation of surgical meshes is the standard procedure to reinforce tissue defects such as hernias. However, an exacerbated and persistent inflammatory response secondary to this implantation is frequently observed, leading to a strong discomfort and chronic pain in the patients. In many cases, an additional surgical intervention is needed to remove the mesh. This study shows that mesenchymal stem cells and their exosomes, combined with a fibrin sealant, can be used for the successful fixation of these meshes. This new therapeutic approach, assayed in a murine model of incisional hernia, favors the modulation of the inflammatory response towards a less aggressive and pro-regenerative profile.

Abstract
Background This study aimed to investigate the predictive value of multislice spiral computed tomography (MSCT) perfusion imaging for the efficacy of preoperative concurrent chemoradiotherapy (CCRT) in middle-aged and elderly patients with locally advanced gastric cancer (LAGC). Material/Methods One-hundred twenty-six middle-aged and elderly patients with LAGC were selected. MSCT was performed before and after CCRT to obtain perfusion parameters: blood flow volume (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS). After CCRT, according to Response Evaluation Criteria in Solid Tumors (RECIST), patients were categorized into the effective group and the ineffective group. Overall survival rate was measured by Kaplan-Meier analysis. ROC curve was applied to evaluate the predictive value of perfusion parameters. Multiple logistic regression analysis was applied to analyze the association of perfusion parameters with the efficacy of preoperative treatment. Results Tumor volume reduction rates of the effective and ineffective groups were 59.23±8.53% and 10.41±3.36%. BF, BV, and PS values in the effective group were significantly decreased after CCRT. ROC curves indicated high sensitivities and specificities of BF value (79.00%, 73.44%), BV value (71.00%, 75.00%), and PS value (82.30%, 90.63%). The incidence rate of weakness and anorexia in the effective group was much higher than that in the ineffective group. Patients with low BF, BV, and PS values (less their optimal cutoff values) had longer survival times than these with high BF, BV, and PS values. Conclusions MSCT might have predictive values for the efficacy of preoperative CCRT in the treatment of LAGC.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is a common cancer with poor prognosis. Caveolin-1 (Cav1) and Rho/ROCK pathway play important roles in tumor metastasis, separately. However, less research was focused on the relationship between Cav1 and Rho/ROCK in ECSS metastasis. Therefore, we investigated the relationship between Cav1 and Rho/ROCK pathway in ESCC metastasis. MATERIAL AND METHODS Cav1 and phosphorylated Cav1 (PY14Cav1) were examined in ESCC and in adjacent and non-tumorous tissues from ESCC patients by immunohistochemistry (IHC). Small interfering RNA (siRNA) targeting Cav1 or Rho/ROCK inhibitor was used to treat EC109, Eca109, TE1, and TE13 cells. Western blotting (WB) was used to detect Cav1 and PY14Cav1 expression. The wound healing scratch test and transwell assays were used to assess migration and invasion. RESULTS Cav1 and PY14Cav1 were gradually expressed at higher levels in ECSS than in adjacent and non-tumor tissues as ESCC stage and lymphatic metastasis increased, and this difference was significant (P<0.05). Cav1 was expressed at higher levels in TE1 and TE13 than in EC109 and Eca109, while PY14Cav1 was enhanced in TE1 and TE13 cells but not in EC109 and Eca109, and the difference was significant (P<0.05). TE1 and TE13 had significantly (P<0.05) stronger motility, migratory, and invasion abilities than EC109 and Eca109 cells. Silencing Cav1 decreased PY14Cav1 expression in TE1 and TE13 cells, as well as suppressing the migration and invasion of all ECSS cells, and these differences were significant (P<0.05). Suppressing the Rho/ROCK pathway obviously inhibited Cav1 and PY14Cav1 expressions, as well as significantly (P<0.05) decreasing migration and invasion of ESCC cells. CONCLUSIONS Cav1 and PY14Cav1 were positively correlated with ESCC lymphatic metastasis and cancer stages. Rho/ROCK pathway activation promoted ESCC metastasis by regulating Cav1.

Abstract
Background Gastric cancer (GC) is one of the most common cause of cancer-related deaths. The clinical trials still lack the effective methods to treat or monitor the disease progression. In this research, the biological function and the underlying molecular mechanism of regenerating protein 1 alpha (REG1A) in GC were investigated. Material/Methods Gene expression omnibus (GEO), KMplot datasets and GC tissue microarray (n=164) were used to analyze the expression of REG1A and related patient prognoses in GC. Transwell matrigel assay, flow cytometry analysis and CCK8 cell viability assay were performed to detect the biological functions of REG1A. Western blotting and real-time PCR were used to detect the REG1A expression and PI3K/Akt related signaling. Results It was found that the expression of REG1A was significantly downregulated in GC and closely related with clinicopathological findings or patient prognoses. REG1A overexpression could suppress the invasion, cell viability and promote the apoptosis of GC cells. Moreover, we found that the epigenetic methylation suppressed the expression level of REG1A in GC, and REG1A overexpression could suppress the phosphorylation of Akt or GSK3β signaling. Conclusions Taken together, REG1A regulates cell invasion, apoptosis and viability in GC through activating PI3K/Akt-GSK3β signaling. REG1A may serve as a promising therapeutic strategy for GC.

Abstract
Background The incarceration of a segment of bowel within a groin hernia can result in intestinal strangulation if hernia treatment is delayed. Once intestinal strangulation occurs, a bowel resection may be required, and there is an overall increased risk for postoperative complications. The aim of this study was to identify biomarkers to predict the severity of an incarcerated groin hernia. Material/Methods We retrospectively evaluated the records of 95 patients with incarcerated groin hernias who underwent emergency surgical correction of the hernias. The need for a bowel resection was regarded as an indicator of severity in incarcerated groin hernia patients. The patients were divided into 2 groups: patients with bowel resection surgery and patients without bowel resection surgery. Results We discovered that leukocyte count (leukocyte count ≥10×103/mm3), neutrophil-to-lymphocyte ratio (NLR, NLR ≥11.5), presentation of bowel obstruction, and duration of incarceration (duration of incarceration ≥26 h) were significantly associated with bowel resection in incarcerated groin hernia patients by using the chi-square test. Factors such as leukocyte count, NLR, presentation of bowel obstruction, and duration of incarceration were analyzed using multivariate logistic regression analysis. We found that NLR, presentation of bowel obstruction, and duration of incarceration were independently and significantly related to bowel resection in incarcerated groin hernia patients. Conclusions An elevated NLR can serve as a biomarker for the prediction of severity of incarcerated groin hernias. Additionally, incarcerated groin hernia patients who present with bowel obstruction or with duration of intestinal incarceration longer than 26 h have an increased risk for bowel resection.

Abstract
Background Conflict still remains as to the benefit of angioembolization (AE) for non-operative therapy (NOT) of blunt hepatic trauma (BHT). The aim of this study was to determine whether AE could result in lower failure rates in hemodynamically stable BHT patients with high failure risk factors for NOT, and to systematically evaluate the effectiveness of AE for NOT of BHT. Material/Methods Medical records of all BHT patients from January 1, 1998 to December 31, 2015 at a large trauma center were collected and analyzed. Failure of NOT (FNOT) occurred if hepatic surgery was performed after attempted NOT. Logistic regression analysis was used to identify factors associated with FNOT. Hepatobiliary complications related to hepatic trauma during follow-up were reviewed. Results No significant difference in FNOT for the no angiographic embolization (NO-AE) group versus angiographic embolization (AE) group was found in hepatic trauma of grades I, II, and V. However, decrease in FNOT was significant with AE performed for hepatic trauma of grades III to IV. Risk factors for FNOT included grade III to IV injuries and contrast blush on CT. Follow-up data of six months also showed that the incidence of hepatobiliary complications in the NO-AE group was higher than the AE group. Conclusions Hemodynamically stable BHT patients with grade III to IV injuries, contrast blush on initial CT, and/or decreasing hemoglobin levels can be candidates for selective AE during NOT course.

Abstract
Background The purpose of this study was to investigate the prognostic significance of methylation of RAS association domain family protein 1 (RASSF1A) in the promoter region for patients with stage II and III colorectal cancer (CRC) receiving oxaliplatin-based chemotherapy. Material/Methods There were 108 eligible CRC patients and 78 healthy controls included in this study. Methylation-specific polymerase chain reaction (MSP) was applied to detect the methylation status of RASSF1A in patients before and after chemotherapy. The effects of RASSF1A methylation on chemotherapy-sensitivity and prognosis for patients were also evaluated in the present study. Results The frequency of RASSF1A methylation was higher in CRC patients than in the healthy controls (48.44% versus 5.13%, p<0.001). After two cycles of chemotherapy, methylation ratio was significantly decreased (21.30%, p<0.001). Promoter methylation of RASSF1A was significantly correlated with tumor stage and pathological differentiation (p=0.008 and p=0.007, respectively). Patients without methylation had a favorable objective response (OR), compared with those with methylation (53.33% versus 25%, p=0.014). Methylation status of RASSF1A could influence progression-free survival and overall survival (log rank test, p<0.05). Cox regression analysis indicated that RASSF1A methylation (HR=2.471, 95% CI=1.125–5.428, p=0.024) and OR (HR=2.678, 95% CI=1.085–6.610, p 0.033) were independently correlated with prognosis for patients treated with oxaliplatin-based chemotherapy. Conclusions Promoter methylation of RASSF1A can influence sensitivity to oxaliplatin-based chemotherapy, which can be used to predict outcomes for patients with stage II and III CRC. In addition, the aberrant methylation may be a promising target for improving chemotherapy efficacy.

Abstract
Background Postsurgical peritoneal adhesions (PPAs) are pathologic fibrous bands within the peritoneal cavity. The aim of this study was to investigate the protective effect of hydrogen-rich saline (HRS) on PPAs formation in mice. Material/Methods Adhesions were induced in mice using the cecum rubbing model. The mice were allocated into 4 groups: control sham group without cecum rubbing; PPA group with saline applied intraperitoneally (i.p.) daily after cecum rubbing; PPA+HRS (5) group with 5 ml/kg of HRS applied i.p. daily after cecum rubbing; and PPA+HRS (10) group with 10 ml/kg of HRS applied i.p. daily after cecum rubbing. On the 1st, 3rd, and 7th days after the operation, mice were killed and pathological adhesion bands were quantified to detect the effect of HRS on PPAs formation. Results HRS did not affect PPAs formation on the 1st day, but did make a significant reduction on the 3rd and 7th days. A significant increase of t-PA and decrease of TGF-β1 and PAI-1 in the peritoneal fluids were observed in the HRS-treated groups. The levels of MDA and MPO in the HRS-treated groups were significantly lower than those in the PPA group. TNF-α and IL-6 levels in HRS-treated groups significantly decreased compared with those in the PPA group on postoperative day 3 and 7. Moreover, HRS decreased the mRNA levels of pro-inflammatory cytokines and TGF-β1 expression in the postsurgical adhesion bands. Conclusions These results showed that HRS had therapeutic potential for preventing PPAs formation, possibly through balancing the expression of TGF-β1, t-PA, and PAI-1, and inhibiting oxidative stress and inflammation.

Abstract
BACKGROUND Increasing evidence suggests that delayed diagnosis in Crohn's disease is associated with a complicated disease course. The aim of this study was to explore the association between delayed diagnosis and the timing of the first Crohn's disease-related intestinal surgery. MATERIAL AND METHODS A retrospective study included 215 Crohn's disease patients with previous surgical history in the Department of General Surgery of Jinling Hospital, China, between January 2013 and March 2016. Data were collected on demographics, clinical characteristics, medication history, and operation history. RESULTS The time from the first appearance of Crohn's disease-related symptoms to the first intestinal surgery in the delayed diagnosis group was obviously shorter than in the non-delayed diagnosis group (26.4±28.7 months vs. 42.6±58.4 months, respectively, p=0.032). Patients in the delayed diagnosis group tended to receive more ileal resections (47.8% vs. 26.4%, respectively, p=0.002) and less ileocecal resections (22.4% vs. 37.2%, respectively, p=0.032). More patients in the delayed diagnosis group received the first Crohn's disease-related intestinal surgery as an emergency one (20.9% vs. 4.7%, respectively, p=0.001). CONCLUSIONS Delayed diagnosis is associated with early and emergency need for the first Crohn's disease-related intestinal surgery.

Abstract
Background Acute myeloid leukemia (AML) is a common hematologic malignancy of adults. The pathophysiological mechanism of AML is not well understood. The purpose of this study was to examine the crucial miRNAs and mRNAs associated with AML survival. Material/Methods The full clinical dataset of miRNA and mRNA expression profiling of AML patients was downloaded from The Cancer Genome Atlas database. Univariate Cox regression analysis was performed to obtain those miRNAs and mRNAs associated with AML survival. A miRNA-mRNA interaction network was constructed. The underlying functions of mRNAs were predicted through Kyoto Encyclopedia of Genes and Genomes (KEEG) pathway enrichment. The expression levels of miRNAs and mRNAs were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Results Fourteen miRNAs and 830 mRNAs associated with AML survival were identified. Of the 14 miRNAs, hsa-mir-425, hsa-mir-1201, and hsa-mir-1978 were identified as risk factors and the other 11 miRNAs were identified as protective factors of AML survival. For target-genes of miRNAs, GTSF1, RTN4R, and CD44 were the top risk factor target-genes associated with AML survival. An interaction network was constructed that including 607 miRNA-target gene pairs associated with AML survival. Target-genes associated with AML survival were significantly enriched in several pathways including pancreatic secretion, calcium signaling pathway, natural killer cell mediated cytotoxicity, and Alzheimer’s disease. The qRT-PCR results were consistent with our bioinformatics analyses. Conclusions The miRNA hsa-mir-425 was identified as the top risk factor miRNA of AML survival and CD44 was identified as one of the top three risk factor target-genes associated with AML survival. Both hsa-mir-425 and CD44 may play key roles in progression and development of AML through calcium signaling pathway and natural killer cell mediated cytotoxicity.

Abstract
Hericium erinaceus (HE), a traditional edible mushroom, is known as a medicine food homology to ameliorate gastrointestinal diseases. To investigate whether HE is clinically effective in alleviating inflammatory bowel disease (IBD), HE extracts (polysaccharide, alcoholic extracts and whole extracts were prepared using solvent extraction methods) were administrated for 2 weeks in rats with IBD induced by trinitro-benzene-sulfonic acid (TNBS) enema (150 mg/kg). Significant clinical and histological changes in IBD rats were identified, including damage activity, common morphous and tissue damage index scores in colonic mucosa and myeloperoxidase (MPO) activity. The damage activity, common morphous and tissue damage index scores in colonic mucosa (P <0.05) were improved, MPO activities were decreased. Inflammatory factors were also differentially expressed in colonic mucosa in IBD rats, including serum cytokines, Foxp3 and interleukin (IL)-10 were increased while NF-κB p65 and tumor necrosis factor (TNF)-α were decreased (P <0.05), and T cells were activated (P <0.05), especially in the alcohol extracts-treated group. We also found that the structure of gut microbiota of the H. erinaceus extracts-treated groups changed significantly by compared with the model group. Further studies revealed that the polysaccharides in HE extracts may play a prebiotic role, whereas the alcoholic extracts show bactericidin-like and immunomodulatory effects. Taken together, we demonstrated that H. erinaceus extracts could promote the growth of beneficial gut bacteria and improve the host immunity in vivo IBD model, which shows clinical potential in relieving IBD by regulating gut microbiota and immune system.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is common all over the world. GDM women are with inflammatory and metabolisms abnormalities. However, few studies have focused on the association of IL-65-72C/G and TNF-α -857C/T single nucleotide polymorphisms (SNPs), inflammatory biomarkers, and metabolic indexes in women with GDM, especially in the Inner Mongolia population. The aim of this study was to investigate the associations of IL-65-72C/G and TNF-α -857C/T SNPs, and inflammation and metabolic biomarkers in women with GDM pregnancies. MATERIAL AND METHODS Blood samples and placentas from 140 women with GDM and 140 women with healthy pregnancies were collected. Matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) and MassARRAY-IPLEX were performed to analyze IL-65-72C/G and TNF-α -857C/T SNPs. Enzyme linked immunosorbent assay (ELISA) was performed to analyze inflammatory biomarkers and adipokines. RESULTS Distribution frequency of TNF-α -857CT (OR=3.316, 95% CI=1.092-8.304, p=0.025) in women with GDM pregnancies were obviously higher than that in women with healthy pregnancies. Women with GDM were of older maternal age, had higher BMI, were more nulliparous, and had T2DM and GDM history, compared to women with healthy pregnancies (p<0.05). Inflammatory biomarkers in serum (hs-CRP, IL-6, IL-8, IL-6/IL-10 ratio) and placental (NF-κB, IL-6, IL-8, IL-6/IL-10 ratio, IL-1b, TNF-α) were significantly different (p<0.05) between women with GDM and women with healthy pregnancies. Differences were found for serum FBG, FINS, HOMA-IR, and HOMA-β, and placental IRS-1, IRS-2, leptin, adiponectin, visfatin, RBP-4, chemerin, nesfatin-1, FATP-4, EL, LPL, FABP-1, FABP-3, FABP-4, and FABP-5. CONCLUSIONS TNF-α -857C/T SNP, hs-CRP, IL-6, IL-8, and IL-6/IL-10 were associated with GDM in women from Inner Mongolia, as was serious inflammation and disordered lipid and glucose metabolisms.

Abstract
Background The purpose of this study was to investigate the impact of the modified Glasgow Prognostic Score (GPS) at the time of recurrence on post-recurrence survival (PRS) in non-small cell lung cancer (NSCLC) patients after surgical resection. Material/Methods The clinicopathologic characteristics and outcome data of 266 patients with recurrent NSCLC were collected and reviewed retrospectively. The prognostic impact of mGPS at recurrence in patients with recurrent NSCLC was investigated in univariate and multivariate analyses. Results A total of 266 patients were analyzed. The mGPS at the time of recurrence of 0, 1, and 2 was assigned to 60.9%, 33.1%, and 6.0% of total patients, respectively. In univariate analyses, the median post-recurrence survival times for those with mGPS 0, 1, and 2 were 19, 14, and 4 months, respectively (log-rank test; P=0.005). No statistically significant difference in post-recurrence survival was observed among the patients with different mGPS before surgery (log-rank test; P=0.064). Age at surgery, histological type, C-reactive protein (CRP), albumin, and mGPS at recurrence significantly predicted PRS. After adjusting for confounding variables in the model, age (hazard ratio 1.59, P=0.003) as well as disease-free interval (DFI) (hazard ratio 1.40, P=0.023), and mGPS at recurrence (hazard ratio 1.47, P=0.002) remained independent predictors of PRS. Conclusions mGPS at the time of recurrence might be an independent adverse prognostic factor in recurrent NSCLC.

Abstract
Background Breast cancer is one of the most common malignancies in women. In a previous study, we found that for two patients who had a high risk of lymphatic metastasis, lymphatic metastasis did not occur; whereas, for two patients who had a low risk of lymphatic metastasis, lymphatic metastasis did occur. Material/Methods We analyzed the differential gene expressions of these four patients by RNA-sequence. The data (HRNM_T versus HRNM_N, LRYM_T versus LRYM_N, and HRNM_T versus LRYM_T) was then processed using differentially expressed genes (DEGs) analysis, functional analysis for DEGs, and PPI network construct. Results For HRNM_T versus HRNM_N, there were 224 DEGs. There were 504 DEGs for LRYM_T versus LRYM_N, and 88 DEGs for LRYM_T versus LRYM_N. For HRNM_T versus HRNM_N, DEGs were up-regulated mainly in the cell cycle, the IL-17 signaling pathway, and the progesterone-mediated oocyte maturation; DEGs were down-regulated mainly in the IL-17 signaling pathway. For LRYM_T versus LRYM_N, DEGs were up-regulated mainly in protein digestion and absorption, and cytokine-cytokine receptor interaction; DEGs were down-regulated mainly in ECM-receptor interaction. For HRNM_T versus LRYM_T, DEGs were up-regulated mainly in the PPAR signaling pathway; DEGs were downregulated mainly in the adipocytokine signaling pathway. The DEGs were screened to construct PPI networks. Conclusions The GO and KEGG functional enrichments of HRNM_T versus HRNM_N, and LRYM_T versus LRYM_N were consistent with earlier studies. For HRNM_T versus LRYM_T, DEGs were up-regulated mainly in PPAR signaling; DEGs were down-regulated mainly in the adipocytokine pathway.

Abstract
Background The aim of this study was to investigate the usefulness of contrast-enhanced ultrasonography (CEUS) in predicting of esophageal varices (EV) and assessing high-risk EV in patients with hepatitis B virus (HBV)-related cirrhosis. Material/Methods Patients with HBV-related cirrhosis who had undergone endoscopy were prospectively recruited. Hepatic dynamic CEUS was performed. Regions of interest (ROI) were drawn on the hepatic artery, hepatic vein, portal vein, and liver parenchyma to measure the corresponding features, such as arrival times. Spearman’s correlation analysis was used to determine the relations between several dynamic CEUS features and the degree of EV. Receiver operating characteristics (ROC) curves were constructed to investigate the diagnostic performance of CEUS in assessing the presence of EV and high-risk EV. Results Fifty-eight patients (44 men; mean age 51.3 years) were included in this study. Of these, 18 (31.0%), 12 (20.7%), 11 (19.0%), and 17 (29.3%) of patients had grade 0, 1, 2, and 3 EV, respectively. Grade 2 and grade 3 EV were considered high-risk EV. Among the CEUS features, the area under the ROC curves of intrahepatic transit time (HV–HA, i.e., the difference between hepatic vein arrival time and hepatic artery arrival time) both for assessment of the presence of EV and high-risk EV (0.883 and 0.915, respectively) were larger than the other indices. HV–HA was negatively correlated with the grade of EV. An HV–HA of under 8.2 s indicated the presence of EV and under 7 s indicated high-risk EV. Conclusions Dynamic CEUS imaging is useful in assessing the presence of EV and high-risk EV in patients with HBV-related cirrhosis.
