Objective To investigate the possible regulating effect of integrin-linked kinase (ILK) towards matrix metalloproteinase-9/tissue inhibitor of metalloproteinase-1 (MMP-9/TIMP-1) ratio in the process of transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) in human kidney proximal tubular epithelial (HK-2) cells.Methods HK-2 cells were cultured and stimulated with 10 ng/ml TGF-β1.Specific ILK-small interfering RNA (ILK-siRNA) was used to inhibit ILK expression.The characteristic epithelial marker (E-cadherin) and mesenchymal marker (α-SMA) of EMT were examined by Real-time reverse transcription polymerase chain reaction (real-time RT-PCR) and Western blot.The expressions of ILK,MMP-9,and TIMP-1 were also examined,to determine the regulating effect of ILK towards MMP-9/TIMP-1 ratio.Results In the HK-2 cells cultured with TGF-β1,the expression of E-cadherin decreased,and α-SMA expression increased;overexpression of ILK and an abnormal changing of MMP-9/TIMP-1 ratio were observed.ILK inhibition by ILK-siRNA could adjust MMP-9/TIMP-1 ratio to near normal.Meanwhile,the overexpressed ILK and α-SMA were decreased.Conclusions Our data indicates that ILK-siRNA successfully inhibits ILK expression,which regulates the MMP-9/TIMP-1 ratio in HK-2 cells.The inhibition of ILK expression suppresses TGF-β1-induced EMT partially.

Objective To analyze the influencing factors of poor anal function after laparoscopic intersphincteric resection(Lap-ISR)for extremely low rectal cancer,and to construct and verify a prediction model based on this model,in order to provide guidance for improving the anal function of patients with extremely low rectal cancer after Lap-ISR.Method A total of 127 patients with extremely low rectal cancer who underwent Lap-ISR in Taizhou People's Hospital from June 2020 to June 2022 were retrospectively selected.Patients were followed up for 12 months after surgery,and postoperative anal function was evaluated by the anal incontinence score(Wexner).According to Wexner score,the patients were divided into good anal function group(106 cases)and poor anal function group(21 cases).The clinical data of patients were collected and the risk factors affecting postoperative poor anal dysfunction were analyzed,and a Nomogram model was constructed to predict the risk of postoperative anal dysfunction in patients after Lap-ISR,and the receiver operating characteristic curve(ROC)was drawn.The area under the curve(AUC)was used to analyze the predictive efficacy of the prediction model for poor anal dysfunction after Lap-ISR.Result The incidence of anal dysfunction after Lap-ISR in patients with extremely low rectal cancer was 16.54％(21/127).Univariate analysis showed that there was no significant difference in gender,age,body mass index,clinical stage,combined underlying diseases,operation time,intraoperative blood loss,anastomosis method,and the distance from the lower edge of the tumor to the dentate line between the two groups(P＞0.05).The proportion of tumor diameter≥5 cm,the proportion of neoadjuvant chemotherapy,the distance between anastomosis and anal verge＜2 cm,and the proportion of anastomotic leakage in the anal dysfunction group were higher than those in the good anal function group(P＜0.05).Cox multivariate regression analysis showed that tumor diameter≥5 cm(OR=5.124),neoadjuvant chemotherapy(OR=5.761)and anastomotic leakage(OR=6.881)were risk factors for postoperative anal function(P＜0.05).Wexner score of patients with tumor diameter ≥5 cm was higher than that of patients with tumor diameter＜5 cm,Wexner score of patients with neoadjuvant chemotherapy was higher than that of patients without neoadjuvant chemotherapy,and Wexner score of patients with anastomotic leakage was higher than that of patients without anastomotic leakage(P＜0.05).Internal validation of Bootstrap method showed that the C-index was 0.785(95％CI:0.692-0.851).The results of ROC curve showed that the sensitivity and specificity of the nomogram model in predicting postoperative poor anal function of patients were 85.70％and 88.70％,respectively,and the AUC was 0.895(95％CI:0.795-0.984).Conclusion Tumor diameter,neoadjuvant chemotherapy and anastomotic leakage are risk factors for poor anal function after Lap-ISR in patients with extremely low rectal cancer.The nomogram risk prediction model based on the above risk factors has a good risk efficiency in evaluating the risk of postoperative anal dysfunction in patients.

Objective To investigate the expression levels of FOXO1 and SMAD4 in esophageal cancer (EC) tissues and their associations with clinicopathological features and prognosis. Methods Tissue samples of cancerous and adjacent non-cancerous tissues were collected from 131 EC patients. Hematoxylin-eosin (HE) staining was performed to observe the pathological morphology of EC and adjacent tissues. The mRNA expression of FOXO1 and SMAD4 was measured using quantitative real-time polymerase chain reaction (qRT-PCR), while the protein expression of FOXO1 and SMAD4 was determined by immunohistochemistry; Spearman's correlation analysis was employed to assess the correlation between FOXO1 and SMAD4 protein expression in EC tissues; Cox regression analysis was conducted to analyze factors influencing the prognosis of EC patients; Kaplan-Meier analysis was used to perform survival analysis for EC patients. Results The expression of FOXO1 mRNA and its protein positive expression rate were significantly higher in the EC tissues than those in the adjacent tissues, whereas the expression of SMAD4 mRNA and its protein positive expression rate were significantly lower (P < 0.05). FOXO1 and SMAD4 were associated with tumor diameter, tumor differentiation, lymph node metastasis and TNM stage (P < 0.05). A negative correlation was observed between FOXO1 and SMAD4 protein expression in EC tissues (r=-0.419, P < 0.05). FOXO1, SMAD4, tumor diameter, differentiation, lymph node metastasis and TNM stage were identified as factors influencing mortality in EC patients (P < 0.05). The 3-year overall survival rate of EC patients was 84.73% (111/131). The 3-year cumulative survival rate was significantly lower in the EC patients with positive FOXO1 expression than in thosewith negative FOXO1 expression (P < 0.05), while it was significantly higher in patients with positive SMAD4 expression than in those with negative SMAD4 expression (P < 0.05). Conclusion The positive expression rate of FOXO1 is higher, while that of SMAD4 is lower in EC tissues. Their protein expressions were associated with clinicopathological features and prognosis in EC patients. FOXO1 and SMAD4 may serve as important biomarkers for predicting the prognosis of EC.

Objective:To investigate the expression of integrin-linked kinase (ILK)/zinc finger transcription factor (Snail) signaling pathway in renal tubular epithelial-mesenchymal transition (EMT) in diabetic nephropathy (DN) and the effect of rhein.Methods:Healthy male Wistar rats of 8 weeks old were randomly divided into normal group, diabetic nephropathy group, rhein intervention group and valsartan intervention group, with 12 rats in each group. Streptozotocin (STZ) was used to induce the diabetic nephropathy model, then rhein intervention group and valsartan intervention group were given rhein 100 mg/(kg·d) and valsartan 30 mg/(kg·d), respectively. At the end of the 8th and 16th week, six rats of each group were killed, in situ lavage kidney, take out the kidney tissue of rats after fixed in wax block and slices. Renal tubular interstitial damage index and the relative area of interstitial collagen evaluated by hematoxylin-eosin (HE) and Masson staining respectively. The protein expression of E-cadherin, α-smooth muscle actin (α-SMA), ILK, Snail and matrix metalloproteinase-9 (MMP-2) in renal tubular epithelial cells were detected by immunohistochemistry.Results:Comparing to normal group, the renal tubular interstitial damage index and relative area of renal interstitial collagen of diabetic nephropathy rats were both increased. The expression of E-cadherin in renal tubular epithelial cells decreased and the expression of α-SMA significantly increased ( P<0.05). Comparing with diabetic nephropathy group, in rhein and valsartan intervention groups, the expression of E-cadherin in renal tubular epithelial cells increased, while the expression of α-SMA significantly decreased ( P<0.05). There was no significant difference in the above indexes between rhein intervention group and valsartan intervention group ( P>0.05). Compared to normal group, the expressions of ILK, Snail, MMP-2 increased progressively with the disease ( P<0.05). Compared with diabetic nephropathy group, rhein and valsartan intervention groups showed significant decrease in expression of ILK, Snail, MMP-2 ( P<0.05). There was no significant difference in the above indexes between rhein intervention group and valsartan intervention group ( P>0.05). Conclusions:Rhein could inhibit EMT progression by down-regulating the expression of ILK/Snail signaling pathway in renal tubular epithelial cells of DN rats.

Objective: To explore the diagnostic value and efficiency of using whole body bone scintigraphy (WBS) combined with the levels of tumor markers to evaluate non-small cell lung cancer (NSCLC) patients with bone metastases. Methods: One-hundred and eighty-five cases of NSCLC, confirmed by pathology or cytological examination from January 2014 to June 2016, were emrolled from the Affiliated Tumor Hospital of Guangxi Medical University. WBS and test results of tumor markers, such as serum carcinoembryonic antigen (CEA), serum carbohydrate antigen (CA125), and cytokeratin CK19 (CYFRA21-1), were analyzed. WBS results were assessed by the Soloway classification criteria and divided into four grades: Correlations between WBS classification and the levels of tumor mark-ers were determined with Spearman correlation analyses. Results: Seventy-eight of the 185 NSCLC patients had bone metastases (a rate of 42.16%). The sensitivity and specificity of WBS were 91.02%(71/78) and 85.98%(92/107), respectively. The CEA, CA125, and CYFRA21-1 levels in bone metastases patients were higher than those in NSCLC patients without bone metastases (P＜0.05). In the 78 patients with bone metastases, there were seven cases of EOD0 (8.98%), 39 cases of EOD1 (50%), 17 cases of EOD2 (21.8%), and 15 cases of EOD3 (19.2%). The correlations between WBS grade and CEA, CA125, and CYFRA21-1 levels were: rs=0.579, 0.274, and 0.327, respectively (P＜0.05). The combined WBS and tumor marker diagnostic performance was significantly better than either alone (AUC=0.922), and their sensitivity and specificity increased (92.3%and 86.0%, respectively). Conclusions: WBS shows high clinical efficacy in the diagnosis of NSCLC with bone metastases. Furthermore, it can be used as a screening test for bone metastases of NSCLC, which has important clinical implications. WBS combined with CEA, CA125, and CYFRA21-1 examination improves the detection rate of NSCLC bone metastases, thereby enhancing its clinical utility.
