    The purpose of the study was to establish a comprehensive differential gene profile for lung cancer patients treated with cisplatin compared with control patients without any chemotherapy drug treatment. The RNA sequencing data and miRNA sequencing data of 108 lung cancer patients treated with cisplatin only and 232 lung cancer patients treated without any chemotherapeutic drugs, were analyzed using differential expression, protein-protein interaction, and immune cell infiltration ratio analysis. Compared with control patients, the cisplatin-treated patients demonstrated 336 differentially expressed genes, which included 48 upregulated genes and 288 downregulated genes. Meanwhile, 12 differentially expressed miRNAs (DEMs), including 7 upregulated miRNAs and 5 downregulated miRNAs showed a differentially expressed pattern. With further instigation, five miRNAs (hsa-miR-548ah, hsa-miR-466, hsa-miR-552, hsa-miR-371a, and hsa-miR-4445) were suggested to be the key targets in the cisplatin-treated patients. At the same time, we also found a significant correlation between the cisplatin treatment and six immune checkpoints including programmed cell death ligand. This study helped us better understand the potential targets and underline molecular mechanisms for cisplatin treatment and provided references to eliminate existing side effects in the future.

    There is a need for objective diagnostic and prognostic biomarkers in Parkinson’s disease (PD), partly given the expected increase in clinical trials aimed at demonstrating a disease-modifying effect in early disease. Alpha-synuclein (α-syn) plays a decisive role in the pathogenesis of PD. Here, we review recent publications exploring established and novel methodologies to detect α-syn species in tissues and biofluids.

    Using immunohistochemistry (IHC), recent studies have focused on the detection of phosphorylated α-syn (p-α-syn) in cutaneous nerve fibers, reporting varying sensitivity and high specificity for the diagnosis of PD. A predilection for p-α-syn depositions in cutaneous autonomic nerve fibers has emerged, possibly contrasting with other synucleinopathies.Novel studies utilizing the seeding propensity of pathological α-syn have generated encouraging results with regard to diagnostic performance in both tissues and biofluids including skin, submandibular gland, and cerebrospinal fluid.

    Detection of neuronal p-α-syn in skin punch biopsies remains a promising minimally invasive diagnostic tool in PD. Seeding assays have emerged as a new method with its diagnostic potential warranting replication in further studies from various tissues and biofluids. Longitudinal studies employing both IHC and seeding assays are needed to identify possible biomarkers of disease progression.

    To review recent findings and research directions on impulse control disorders and related behaviors (ICDRBs) in Parkinson’s disease (PD).

    Longitudinal studies found that prevalence increases during PD progression, incident ICDRBs being around 10% per year in patients treated with dopaminergic therapies. find more Screening tools and severity scales already developed have been validated and are available in several countries and languages. The main clinical risk factors include young age, male gender, type, doses and duration of dopaminergic therapy, PD motor severity and dyskinesia, depression, anxiety, apathy, sleep disorders, and impulsivity traits. Genetic factors are suspected by a high estimated heritability, but individual genes and variants remain to be replicated. Management of ICDRBs is centered on dopamine agonist decrease, with the risk to develop withdrawal symptoms. Cognitive behavioral therapy and subthalamic nucleus deep brain stimulation also improve ICDRBs. In the perspective of precision medicine, new individual prediction models of these disorders have been proposed, but they need further independent replication.

    Regular monitoring of ICDRB during the course of PD is needed, particularly in the subject at high risk of developing these complications. Precision medicine will require the appropriate use of machine learning to be reached in the clinical setting.

    Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment.

    This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Prohose reported for other ethnicities.

    Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.
