sing speed. These specific patients at-risk might benefit from early-stage interventions. Furthermore, based on future validation studies, imaging-informed surgical and radiotherapy planning could further be improved.

Previous studies showed that both immune checkpoint inhibitors (ICIs) and anlotinib have central nervous system (CNS) efficacy. This study aimed to evaluate the efficacy and safety of ICIs combined with anlotinib in small cell lung cancer (SCLC) patients with brain metastases (BMs).

We retrospectively reviewed SCLC patients with CNS metastases confirmed by brain magnetic resonance imaging (MRI). Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) and Response assessment in neuro-oncology brain metastases (RANO-BM) were used to evaluate treatment response to ICIs plus anlotinib. Kaplan-Meier analysis and Cox regression analysis were performed to determine patient's prognosis.

Sixty-six patients with baseline BMs were included. For patients with measurable intracranial lesions, the intracranial objective response rate (ORR) was 29.2% based on RECIST 1.1 criteria and was 27.1% based on RANO-BM criteria. The median intracranial progression-free survival (PFS) was 9.0months (95% confidence interval [CI], 6.5-11.5months). The median overall survival (OS) was 13.4months (95% CI, 10.7-20.5months). Multivariate Cox regression analysis showed that high disease burden (hazard ratio [HR] = 4.83, P < 0.001), multiple BMs (HR = 2.71, P = 0.036), and more than or equal to 3 prior lines of therapy (HR = 2.56, P = 0.023) were independent negative predictors of OS. The overall incidence of treatment-related adverse events (TRAEs) was 75.8%, and grade 3-4 TRAEs were reported in 19.7% of patients.

Our results suggested that ICIs plus anlotinib had potent CNS efficacy with tolerable toxicity and could be a promising treatment option for SCLC patients with BMs.

Recent studies have reported that activated microglia induce two types of reactive astrocytes. A1 astrocytes could cause neuronal death and synaptic damage, as well as impaired phagocytosis. Therefore, the purpose of this study was to investigate whether unconjugated bilirubin (UCB)-induced A1-like astrocytes take on a neuroinflammation type and the underlying regulatory mechanisms. In this study, primary cortical astrocytes were treated with UCB in vitro. We detected the expression of complement component 3 (C3), S100 calcium binding protein A10 (S100A10), nuclear factor kappa B (NF-κB), NLR family pyrin domain containing 3 (NLRP3), activated caspase-1, gasdermin D N-terminal (GSDMD-N), PSD95, synaptophysin (SYP), the transcription levels of interleukin (IL)-1β and IL-18, and the survival rate of astrocytes after UCB treatment. The results showed that an increase in C3 was accompanied by a decrease in S100A10, and that A1-like astrocytes were functionally expressed after UCB stimulation. Meanwhile, the NF-κB and caspase-1 pathways were activated after UCB stimulation. After adding the NF-κB-specific inhibitor trans-activator of transcriptional-NEMO-binding domain (TAT-NBD) and caspase-1 specific inhibitor VX-765, the survival rate of astrocytes and neurons increased, whereas the protein expression of C3, NF-κB, NLRP3, activated caspase-1, and GSDMD-N decreased, and the mRNA levels of IL-1β and IL-18 reduced. Thus, we concluded that UCB stimulates the activation of A1-like astrocytes. selleckchem Inhibition of NF-κB and caspase-1 alleviated A1-like astrocytes and exerted anti-inflammatory protective effects.

To evaluate the effect of continuous positive airway pressure (CPAP) on the quality of life (QoL) in patients with multiple system atrophy (MSA) and their caregivers.

We reviewed the electronic medical records of patients with MSA treated with CPAP (n = 15). After CPAP treatment, we checked the patient global impression of change (PGI-C) scale for sleep complaints and QoL for six patients who continued to use CPAP. QoL was alsoassessed forfive caregiversof these patients.

A total of 15 patients (6 women) were included. The mean age was 63.6 ± 8.1years old and the mean disease duration was 4.9years. The mean duration of CPAP treatment was 22.1 ± 10.6months and the average compliance was 90%. Three patients died during CPAP treatment, and two patients discontinued CPAP after tracheostomy. For six patients who continued to use CPAP, sleep complaints minimally improved. Five patients reported an improved QoL, and all five caregivers reported improved caregivers' QoL.

This study showed that the use of CPAP has a beneficial effect on sleep complaints and QoL of patients with MSA and their caregivers.

The study aimed to evaluate the association of UCP2 gene polymorphism - 866 G/A and its expression with diabetes predisposition in the North Indian population.

The study involved 850 subjects, including 425 each T2DM and control subjects. The serum metabolic and clinical parameters were estimated using standard protocols. The PCR-RFLP based genotyping was performed to determine UCP2 gene polymorphism, while the expression was measured by real-time quantitative PCR.

The genotypic and allelic frequencies showed a significant difference in cases compared to controls (p < 0.05). The diabetes patients had a 4.2-fold decrease in UCP2 gene expression. The expression was 29.8 and 8.4 fold lower in diabetes patients with homozygous (AA) and heterozygous (GA) mutation at - 866 locus of UCP2 nucleotide sequence, respectively. When categorized according to age and BMI, the T2DM subjects with age ≥ 50 and BMI ≥ 25 had a 5.53 and 8.2-fold decrease in UCP2 expression, respectively. The diabetes subjects with homozysion of T2DM. Moreover, age ≥ 50 years and BMI ≥ 25 could be considered risk factors for developing T2DM in the studied population.Nowadays, microbial synthesis has become a common way for producing valuable chemicals. Traditionally, microbial production of valuable chemicals is accomplished by a single strain. For the purpose of increasing the production titer and yield of a recombinant strain, complicated pathways and regulation layers should be fine-tuned, which also brings a heavy metabolic burden to the host. In addition, utilization of various complex and mixed substrates further interferes with the normal growth of the host strain and increases the complexity of strain engineering. As a result, modular co-culture technology, which aims to divide a target complex pathway into separate modules located at different single strains, poses an alternative solution for microbial production. Recently, modular co-culture strategy has been employed for the synthesis of different natural products. Therefore, in this review, various chemicals produced with application of co-cultivation technology are summarized, including co-culture with same species or different species, and regulation of population composition between the co-culture members. In addition, development prospects and challenges of this promising field are also addressed, and possible solution for these issues were also provided.

Duodenal underwater endoscopic mucosal resection (UEMR) has been suggested as a feasible treatment option for superficial non-ampullary duodenal epithelial tumors (SNADETs). However, its efficacy and safety have not been fully established yet. Thus, the objective of this systematic review and meta-analysis was to determine the efficacy and safety of UEMR as compared with conventional endoscopic mucosal resection (CEMR) in the treatment of SNADETs.

We conducted a comprehensive literature search in PubMed, EMBASE, the Cochrane Library. Studies comparing CEMR and UEMR for the resection of SNADET were included. Outcomes included en-bloc and complete resection rates, adverse events, and procedure time.

A total of six studies with 2454 lesions were included in the quantitative synthesis. En-bloc and complete resection rates were not significantly different between UEMR and CEMR (OR for en-bloc resection 0.997 [95% CI 0.439-2.266]; OR for complete resection 0.960 [95% CI 0.628-1.468]). There was no significant risk difference for perforation (risk difference - 0.002; 95% CI - 0.009 to 0.005) or delayed bleeding (risk difference - 0.001; 95% CI - 0.014 to 0.011). Procedure time was significantly shorter in the UEMR (standardized mean difference - 1.294; 95% CI - 2.461 to - 0.127). The risk of recurrence was not significantly different between UEMR and CEMR (risk difference 0.001; 95% CI - 0.041 to 0.044).

Although our results did not show any superiority of UEMR over CEMR in the treatment of SNADETs, UEMR showed equivalent efficacy and safety as compared with CEMR and was associated with a shorter procedure time.

Several studies showed muscularis macrophages (MMφ) are associated with GI motility disorders. The purpose of this study was to preliminary explore the association between MMφ and achalasia.

Tissue samples of the lower esophageal sphincter (LES) high-pressure zone were obtained from 27 achalasia patients and 10 controls. Immunohistochemistry for MMφ, interstitial cells of Cajal (ICC), neuronal nitric oxide synthase (nNOS), and glial cells were conducted. Histological characteristics were compared between groups, and correlation analysis was performed.

Fewer ICC was found in achalasia compared with controls (P = 0.018), and the level of M1 macrophages was higher than that in controls no matter in terms of the number or the proportion of M1(P = 0.026 for M1 and 0.037 for M1/MMφ). Statistical differences were found between two groups in terms of proportion of M2 and ratio of M1 to M2 (P = 0.048 for M2/ MMφ and < 0.001 for M1/M2). For the correlation analysis, significant correlations were detected between levels of nNOS, ICC, and glial cells in patients with achalasia (P = 0.026 for nNOS and ICC, 0.001 for nNOS and glial cells, 0.019 for ICC and glial cells). There were significant correlations between M2/MMφ and levels of ICC (P = 0.019), glial cells (P = 0.004), and nNOS (P = 0.135).

Patients with achalasia had a higher level of M1/M2 ratio in LES and significant correlations were found between M2/MMφ and numbers of ICC and glial cells, which suggested that MMφ were probably associated with occurrence and development of achalasia.
