Multiple C-H bond functionalizations promptly install diverse groups on the molecular framework and consequently fabricate complex molecular entities. This review briefly surveys the conceptual development of directing group assisted unsymmetrical multiple functionalization of arene C(sp2 )-H bonds, which is exceedingly appealing and highly important.<br /><br /> B-cell acute lymphoblastic leukemia (B-ALL) is the most commonly diagnosed childhood malignancy worldwide and is especially common in Mexico. Additionally, the number of cases has increased in recent years. Thus, it is very important to develop molecular strategies to diagnose leukemia. The aim of this study was to investigate MYB expression and to determine its impact on the diagnosis of B-ALL.<br /><br /> We analyzed the B-ALL gene expression profile by microarray data mining. Bioinformatics analysis was performed to identify the genes that are overexpressed in leukemia. We determined that MYB was highly expressed in leukemia. Then, we validated MYB expression in 70 patients with B-ALL and in 16 healthy controls (HCs) using qRT-PCR. The results were statistically analyzed using the Kolmogorov-Smirnov Z test, Mann-Whitney U test, receiver operating characteristic curves, and the Youden index.<br /><br /> The microarrays showed that MYB was overexpressed in B-ALL patients with a fold change of 57.8728 and a P value of 2.56<br /><br /> . MYB expression showed great variability among the patients analyzed. However, compared to the HCs, the B-ALL patients had a P value&lt;.0001, an area under the curve of 0.813, and a Youden index of 1.46, indicating the statistical significance.<br /><br /> MYB expression in B-ALL cells could be a potential molecular marker for childhood leukemia.<br /><br />MYB expression in B-ALL cells could be a potential molecular marker for childhood leukemia.<br /><br /> The aim of the study was to compare the therapeutic strategies and prognostic factors of patients with primary intestinal diffuse large B-cell lymphoma (PI-DLBCL).<br /><br /> A total of 50 PI-DLBCL patients who accepted standard first-line treatment at National Cancer Center in China were included in this retrospective study. Survival analysis was performed to evaluate the prognostic risk factors.<br /><br /> The 3-year overall survival (OS) and 3-year progression-free survival (PFS) for the entire group were 76.0% and 65.9%, respectively. Univariate analysis showed that B symptom, advanced Lugano stage, elevated LDH status, poor ECOG PS and immunochemotherapy alone were significantly correlated with a poor PFS. Elevated LDH status, poor ECOG PS, advanced Lugano stage, high IPI score and immunochemotherapy alone were significantly correlated with a poor OS. Multivariate analysis revealed that ECOG PS (P=0.035; HR=0.233; 95% CI, 0.060-0.905), LDH level (P=0.010; HR=0.223; 95% CI, 0.072-0.693) and surgery (P=0.002; HR=5.584; 95% CI, 1.883-16.563) were independent prognostic factors for OS. LDH level (P=0.035; HR=0.210; 95% CI, 0.049-0.894) and surgery (P=0.003; HR=6.410; 95% CI, 1.903-21.593) were independent risk factors for PFS in PI-DLBCL. R-CHOP immunochemotherapy combined surgery treatment was also associated with a lower rate of refractory/relapsed (R/R) disease (P=0.004). Furthermore, stratified analysis revealed that partial resection or radical resection combined with immunochemotherapy had no significantly difference which affect OS (P=0.338) and PFS (P=0.207).<br /><br /> R-CHOP immunochemotherapy plus surgery was associated with a superior prognosis compared with R-CHOP alone in Chinese PI-DLBCL population.<br /><br />R-CHOP immunochemotherapy plus surgery was associated with a superior prognosis compared with R-CHOP alone in Chinese PI-DLBCL population.<br /><br /> Occlusal splints are often used to curb the impacts of sleep bruxism (SB) on the dentition, and over-the-counter (OCT) options are becoming increasingly popular. OTC splints are usually fabricated at home by patients, but not routinely evaluated by dental professionals. It is unclear how OCT splints compare with more traditional splints that receive dental oversight.<br /><br /> The present randomized controlled study tested how an OTC splint compared with a gold standard bite splint in terms of patient compliance (primary outcome) and efficacy (secondary outcomes).<br /><br /> Sixty-seven subjects were randomly assigned to receive either the OTC (SOVA, N = 35) splint or the gold standard "Michigan" bite splint (MI, N = 32), with 61 completing the study (SOVA, N = 30; MI, N = 31). OTC-splint subjects were required to fabricate their splints to clinically acceptable standards. Both groups wore the splints nightly for four months. Compliance was measured via daily diary. Efficacy outcomes evaluated stability, retention, periodontal health, night-time rhythmic masticatory muscle activity (RMMA), and material wear.<br /><br /> OTC-splint subjects had difficulty fabricating splints to clinically acceptable standards. The number of night-time RMMA bursts was significantly greater for the OTC splint group. Compliance and all other efficacy measurements were not significantly different between-groups.<br /><br /> The results support the potential use of OTC splints for curbing the impacts of SB. However, the results strongly suggest that dentists should be actively engaged in overseeing patients' use of self-fabricated appliances.

Currently, few studies compare the clinicopathological characteristics and explore the treatment strategies applied to them.<br /><br /> Between July 2005 and April 2016, the clinical records of 297 postoperative patients with pathologically confirmed SCLC were retrospectively analyzed. Kaplan-Meier method and Cox regression model were separately used for stratified univariate and multivariate survival analysis.<br /><br /> A total of 46 cases (15.5%) of C-SCLCs and 251 cases (85.5%) of pure SCLCs (P-SCLCs) were included in this study.

More patients had a history of smoking in C-SCLC (78.3% vs. 63.3%; P = 0.074). The five-year overall survival (OS) rate for P-SCLCs and C-SCLCs was 65.1% and 56.7%, respectively (P = 0.683). For P-SCLC, stage and an intervention of prophylactic cranial irradiation (PCI) were independent factors that affected OS.
