This article aims to analyze the development of Islamic education in Indonesia and efforts to strengthen it in the national education system. This type of research is descriptive qualitative. The study of literature by focusing on terms of peeling, summarizing and collecting a literature, then the authors provide an analysis of the data that has been collected. The results showed that during the pre-independence era religious education was not only not recognized but also not included in the education system, it was even suspected of being a place to incite and fight the invaders. At the time of independence it did not yet have a role because the government still tended to be controlled by nationalist and secular groups, if there were Islamic groups, Islam was still more abangan. Thus the New Order government continuously fostered the quality of madrasa education so that in 1975 a joint decree (SKB) was issued by three ministers on Improving the Quality of Education in Madrasas, where the SKB of the three ministers had advantages and disadvantages. So that the solution of this weakness is the government is trying to make breakthroughs to restore the function of the madrasa as a place to print religious leaders, namely by opening an alternative Madrasah Aliyah named Madrasah Aliyah Special Program (MAPK). Henceforth, this MAPK was changed to Madrasah Aliyah Religious (MAK) which focuses and strengthens the field of Islamic education. There are two strengthening of Islamic education in the national education system, namely strengthening Islamic educational institutions, and strengthening religious subjects in all schools both under the auspices of the Ministry of Religion and other Ministries.

Aim: to evaluate the effect of the lymphadenectomy (LD) level on the quality of life (QoL) in patients who underwent laparoscopic colon resection for colon cancer.Patients and methods: the study included 86 patients who underwent surgery for colon cancer from January 2018 to August 2020. The patients were randomized in 2 groups: the main group — with D3 lymphadenectomy — 41 patients and the control group — with D2 — 45 patients. Two validated QoL questionnaires (QLQ-C30 v. 3.0, QLQ-CR29 v. 2.1) of the European Organization for Research and Treatment of Cancer (EORTC) were applied by the patients on the day before the surgery and on the 30th day after the surgery and were used for the further analysis.Results: there were no significant differences between the groups in gender, age, weight, height, BMI, assessment of functional and physical status according to the ASA and ECOG scales, incidence of comorbidities, tumor site, type and volume surgical of procedures. Regardless of the level of lymphadenectomy, the significant improvement in QoL after surgery was obtained (pQoLD3 = 0.005, pQoLD2 = 0.023) in both groups. The significant increase in the incidence of diarrhea by 2.65 times was detected after laparoscopic right hemicolectomies with extended lymphadenectomy (p = 0.042). Also, there was a significant 2.45 fold increase in the risk of developing erectile dysfunction (ED) after D3 lymphadenectomy in the patients who underwent laparoscopic resections of the left colon in the early postoperative period (p = 0.031).Conclusion: the analysis of physical, social functioning and symptomatic scales has established that in patients who underwent colon resection for cancer of the left colon erectile dysfunction occurred to a greater extent after D3 LD, whereas diarrhea was more likely to develop after resection of the right colon with D3 LD than with D2 LD.

Background: endoscopic electroexcision is the standard technique for the removal of colorectal polyps. However, it is associated with the postoperative morbidity. In order to reduce the incidence of complications, “cold” excision seems to be an alternative option.Aim: to improve the results of endoscopic treatment for patients with colorectal polyps.Patients and methods: from September 2019 to September 2020, 160 patients ≥ 18 years old (80 in each group), who underwent endoscopic removal of colorectal polyps ≤ 10 mm in size by cold excision (132 lesions) and traditional polypectomy (129 lesions), were included in a prospective randomized trial. All removed specimens were studied histologically with an assessment of the resection margins (R0/R1). The analysis of the postoperative complications after endoscopic polypectomy and the incidence of Rx resection after removal of polyps by both techniques was done.Results: the compared groups were homogenous in the number of patients, gender, age, and comobridities. There were no significant differences in the number of removed polyps, their site and the type according to endoscopic classifications. The operation time was significantly higher in the conventional polypectomy group compared with the “cold” one (p = 0.0001). There were no significant differences in the intraoperative complications rate between the two groups (p = 0.06). There were no postoperative complications in the “cold” group. In the control group postoperative complications occurred after 12 out of 129 polyps removal (p = 0.001). The univariate analysis showed that a risk factor for the development of postoperative complications after conventional polypectomy is the lack of submucosal lifting (OR: 15.3, 95% CI: 1.9-125.6, p = 0.01). Histopathology of the removed specimens showed that in both groups most of the procedures were considered as R0 resections (54% in the main group, 56.4% in the control group, p = 0.8). The polyp size ≤ 4 mm identified as a risk factor for R1, Rx resection (OR: 2.4, 95% CI: 1.3–4.7, p = 0.007).Conclusion: “cold” polypectomy is an effective and safe method and may be recommended as an alternative technique for the removal of non-pedunculated colorectal polyps ≤ 10 mm.

Published: July 2021

BackgroundChemoresistance is emerging as a major barrier to successful treatment in acute myeloid leukemia (AML), and bone marrow stromal cells (BMSCs) protect leukemia cells from chemotherapy eventually leading to recurrence. This study was designed to investigate the role of p21-activated kinase 1 (PAK1) in AML progression and chemosensitivity, highlighting the mechanism of stroma-mediated chemoresistance.MethodsThe GEPIA and TCGA datasets were used to analyze the relationship between PAK1 mRNA expression and various clinical parameters of AML patients. Cell proliferation and apoptosis were examined to evaluate the role of PAK1 on chemosensitivity in AML by silencing PAK1 with shRNA or small molecular inhibitor. Human BMSC (HS-5) was utilized to mimic the leukemia bone marrow microenvironment (BMM) in vitro, and co-culture model was established to investigate the role of PAK1 in BMSC-mediated drug resistance.Resultsp21-activated kinase 1 high expression was shown to be associated with shorter overall survival in AML patients. The silence of PAK1 could repress cell proliferation, promote apoptosis, and enhance the sensitivity of AML cells to chemotherapeutic agents. More importantly, BMSCs induced PAK1 up-regulation in AML cells, subsequently activating the ERK1/2 signaling pathway. The effect of BMSC-mediated apoptotic-resistance could be partly reversed by knock down of PAK1.Conclusionp21-activated kinase 1 is a potential prognostic predictor for AML patients. PAK1 may play a pivotal role in mediating BMM-induced drug resistance, representing a novel therapeutic target in AML.

Objective: This study investigated the association of metabolic syndrome (MS) and its components with cardiac, macro-, and micro-circulatory abnormalities in an elderly Chinese population.Methods: This cross-sectional study was conducted using data for 1,958 participants from the Northern Shanghai Study aged over 65 years without a history of cardiovascular disease. MS was defined according to the National Cholesterol Education Program Adult Treatment Panel III in 2005 (NCEPIII 2005). Asymptomatic cardiovascular impairment parameters, including the left ventricle mass index (LVMI), peak transmitral pulsed Doppler velocity/early diastolic tissue Doppler velocity (E/Ea), carotid-femoral pulse wave velocity (cf-PWV), ankle-brachial index (ABI), carotid intima-media thickness (CIMT), arterial plaque, and urinary albumin–creatinine rate (UACR), were evaluated.Results: LVMI, E/Ea, cf-PWV, and the proportion of UACR &gt; 30 mg/g exhibited increasing trends while ABI exhibited a decreasing trend according to the number of MS components (all p for trend &lt; 0.01). Logistic regression analysis revealed that MS was significantly associated with LV hypertrophy (LVH), LV diastolic dysfunction, arteriosclerosis, and microalbuminuria (all p &lt; 0.001). Central obesity and high blood pressure were associated with all cardiovascular abnormalities (all p &lt; 0.05), whereas elevated plasma glucose was associated with arteriosclerosis and microalbuminuria (both p &lt; 0.001). In addition, high triglyceride levels were associated with microalbuminuria (p &lt; 0.05).Conclusions: MS is significantly associated with cardiac, macro-, and micro-circulatory abnormalities in elderly Chinese. Moreover, the presence of individual MS components may have specific prognostic significance.

Published: July 2021

BackgroundAntiangiogenic agents that specifically target vascular endothelial growth factor receptor (VEGFR), such as sunitinib, have been utilized as the standard therapy for metastatic clear cell renal cell carcinoma (ccRCC) patients. However, most patients eventually show no responses to the targeted drugs, and the mechanisms for the resistance remain unclear. This study is aimed to identify pivotal molecules and to uncover their potential functions involved in this adverse event in ccRCC treatment.MethodsTwo datasets, GSE64052 and GSE76068, were obtained from the Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) were identified using the limma package in R software. The gene set enrichment analysis (GSEA) was conducted using clusterProfiler package. A protein–protein interaction (PPI) network was built using the STRING database and Cytoscape software. Kaplan—Meier survival curves were plotted using R software. qRT-PCR and Western blotting were used to detect the MX2 and pathway expression in RCC cell lines. Sunitinib-resistant cell lines were constructed, and loss-of-function experiments were conducted by knocking down MX2. All statistical analyses were performed using R version 3.6.1 and SPSS 23.0.ResultsA total of 760 DEGs were derived from two datasets in GEO database, and five hub genes were identified, among which high-level MX2 exhibited a pronounced correlation with poor overall survival (OS) in sunitinib-resistant ccRCC patients. Clinical correlation analysis and Gene Set Variation Analysis (GSVA) on MX2 showed that the upregulation of MX2 was significantly related to the malignant phenotype of ccRCC, and it was involved in several pathways and biological processes associated with anticancer drug resistance. qRT-PCR and Western blotting revealed that MX2 was distinctly upregulated in sunitinib-resistant RCC cell lines. Colony formation assay and Cell Counting Kit-8 (CCK8) assay showed that MX2 strongly promoted resistant capability to sunitinib of ccRCC cells.ConclusionMX2 is a potent indicator for sunitinib resistance and a therapeutic target in ccRCC patients.

Background and aimsGroup 2 innate lymphoid cells (ILC2s) have been implicated in the regulation of metabolic homeostasis in mice.MethodsIn this study, the role of ILC2s in white adipose tissue (WAT) was investigated using ST2, an IL-33 receptor that is expressed on ILC2 knockout mice.ResultsThe deficiency of ST2 decreased ILC2s in WAT, whereas ex-ILC2, which acquired group 1 innate lymphoid cell (ILC1)-like traits, was increased. This led to significant metabolic disorders such as visceral fat obesity, decreased browning in WAT, reduction of energy metabolism, and impaired glucose tolerance, compared to wild type (WT) mice. Those metabolic abnormalities of ST2-knockout (ST2KO) mice were not ameliorated by IL-33 administration, but impaired glucose tolerance and visceral fat obesity were significantly improved by transplantation of ILCs from the bone marrow of WT mice. The relative expression of Cd36 in WAT increased due to the deficiency of ST2, and the storage of saturated fatty acids in WAT of ST2KO mice was significantly higher than that of WT mice. Moreover, saturated fatty acids aggravated the chronic inflammation in adipocytes, promoted the differentiation of M1-like macrophages, and inhibited that of M2-like macrophages.ConclusionsOur results indicated that ILC2 regulates diet-induced obesity and chronic inflammation through the regulation of saturated fatty acid absorption in visceral adipose tissue.

The protein tyrosine phosphatase receptor type-C (PTPRC) gene encodes the common leukocyte antigen (CD45) receptor. CD45 affects cell adhesion, migration, cytokine signalling, cell development, and activation state. Four families of the gene have been identified in cattle: a taurine group (Family 1), two indicine groups (Families 2 and 4) and an African “taurindicine” group (Family 3). Host resistance in cattle to infestation with ticks is moderately heritable and primarily manifests as prevention of attachment and feeding by larvae. This study was conducted to describe the effects of PTPRC genotype on immune-response phenotypes in cattle that display a variable immune responsiveness to ticks. Thirty tick-naïve Santa-Gertrudis cattle (a stabilized composite of 5/8 taurine and 3/8 indicine) were artificially infested with ticks weekly for 13 weeks and ranked according to their tick counts. Blood samples were taken from control and tick-challenged cattle immediately before, then at 21 d after infestation and each subsequent week for 9 weeks. Assays included erythrocyte profiles, white blood cell counts, the percentage of cellular subsets comprising the peripheral blood mononuclear cell (PBMC) population, and the ability of PBMC to recognize and proliferate in response to stimulation with tick antigens in vitro. The cattle were PTPRC genotyped using a RFLP assay that differentiated Family 1 and 3 together (220 bp), from Family 2 (462 bp), and from Family 4 (486 bp). The PTPRC allele frequencies were Family 1/3 = 0.34; Family 2 = 0.47; Family 4 = 0.19. There was no significant association between PTPRC genotype and tick count. Each copy of the Family 1/3 allele significantly decreased total leucocyte count (WCC) and CD8+ cells. Increasing dosage of Family 2 alleles significantly increased red blood cell count (RCC), haematocrit (PCV), and haemoglobin (Hb) concentration in blood. Increasing dosage of the Family 4 allele was associated with increased WCC, reduced RCC, reduced PCV and reduced Hb. Homozygote Family 1/3 animals had consistently lower IgG1 in response to tick Ag than homozygote Family 2 animals. The PTPRC genotype influences the bovine immune response to ticks but was not associated with the observed variation in resistance to tick infestation in this study.

This study focuses on the microstructure characteristics and tensile and creep properties of a near α high temperature Ti-6.6Al-4.6Sn-4.6Zr-0.9Nb-1.0Mo-0.32Si alloy. Microstructure characteristics were quantitatively investigated using optical microscopy, scanning electron microscope, and transmission electron microscopy. Tensile properties were carried out at room and high temperature. Creep properties were detected under applied stresses ranging from 100–350 MPa at 873–973 K, respectively. Results showed that Widmanstätten microstructure was obtained after hot forged and heat treatment. The strength decreases and the elongation rises with temperature increasing. The ultimate strength and elongation were 1010 MPa, 12% at room temperature, and 620 MPa, 20% at 923 K, respectively. The steady state creep rates rise correspondingly with stress and temperature. Stress exponents are measured within the range of 3.0–3.5. Thus, the creep mechanism is diffusion-controlled viscous glide of dislocation. Ti3Al precipitates are observed. The boundaries and precipitates can obstruct dislocation movement to improve the creep properties. Fracture mechanism of creep is intergranular. The creep mechanism varied from climb of dislocation to sliding of dislocation solution.

Background: Polyethylene glycol interferon alpha (PEG-IFN-α) is the most frequently used pharmacotherapeutic approach in patients infected with hepatitis B virus (HBV). Numerous studies have reported that interleukin-28B (IL-28B) genetic polymorphisms are related to the therapeutic efficacy of PEG-IFN-α, but the results are inconsistent. The present meta-analysis aimed to analyze the association between IL-28B genetic polymorphisms and the prognosis of patients with chronic hepatitis B (CHB) treated with PEG-IFN-α to inform clinical practice.Methods: PubMed, EBSCO, and Scopus databases were searched for relevant literature published before February 30, 2021. We calculated the crude odds ratios (ORs) with 95% confidence intervals (CIs) of the cited articles. A total of 2510 patients with CHB treated with PEG-IFN-α in 13 clinical cohort studies were analyzed.Results: The overall analysis demonstrated a potential association between IL-28B genetic polymorphisms and response to PEG-IFN-α; however, the association was not statistically significant. Furthermore, the subgroup analysis revealed that among patients with HBeAg-negative CHB, the rs12979860 CC genotype and rs8099917 TT genotype were associated with more significant treatment response to PEG-IFN-α (CC vs. non-CC: OR 2.78, 95% CI 1.00–7.76, I2 = 83%; TT vs. non-TT: OR 2.16, 95% CI 1.35–3.48, I2 = 0%). Among Asian patients with CHB, the rs12979860 CC genotype was associated with a more significant treatment response to PEG-IFN (CC vs. non-CC: OR 1.88, 95% CI 1.18–2.99, I2 = 0%).Conclusion: This meta-analysis revealed that the IL-28B rs12979860 CC genotype and rs8099917 TT genotype indicated a better treatment response than non-CC and non-TT genotypes for PEG-IFN-α in patients with CHB.

Background: To optimize [18F] 9-fluoropropyl-(+)-dihydrotetrabenazine (18F-FP-(+)-DTBZ) purification via solid-phase extraction (SPE) with combined cartridges to facilitate its widespread clinical application.Methods: A modified SPE purification method, employing Sep-Pak PS-2 and Sep-Pak C18 cartridges, was used for the preparation of 18F-FP-(+)-DTBZ. This method was compared to the purification method of high-pressure liquid chromatography (HPLC) and SPE with one cartridge, following quality control test and positron emission tomography (PET) imaging in healthy volunteers and patients with parkinsn's disease (PD).Results: A SPE purification method integrating Sep-Pak PS-2 and Sep-Pak C18 cartridges was implemented successfully. The retention time of 18F-FP-(+)-DTBZ purified by HPLC, SPE with Sep-Pak PS-2, SPE with Sep-Pak C18, and SPE with combined use of Sep-Pak PS-2 and Sep-Pak C18 cartridges was 8.7, 8.8, 8.7, and 8.9 min, respectively. Fewest impurity peak was detected in 18F-FP-(+)-DTBZ purified by the SPE with combined use of Sep-Pak PS-2 and Sep-Pak C18 cartridges. This modified SPE purification method provided a satisfactory radiochemical yield of 29 ± 1.8% with radiochemical purity &gt;99% and shortened synthesis time to 27 min. The brain uptake of 18F-FP-(+)-DTBZ purified by the modified SPE was comparable to that purified by HPLC in both healthy volunteers and PD patients.Conclusions: A SPE method integrating Sep-Pak PS-2 and Sep-Pak C18 cartridges for purification of 18F-FP-(+)-DTBZ may be highly suited to automatic synthesis for routine clinical applications, as it provides excellent radiochemical purity, high yield as well as operational simplicity.
