Objective:To investigate the correlation between macular cherry red spot (CS) and severity of neurological manifestations in Chinese children with sialidosis (SD) type I.Methods:A evidence-based medical study. "China", "Sialidosis" and "Sialidoses" were used as Chinese and English search terms. The literature was searched in CNKI, Wanfang and PubMed. The cases were all from China and matched the diagnostic criteria. According to the presence or absence of CS in the fundus, the SD children were divided into a group with CS (+) and a group without CS (-), and the correlation between the occurrence of ocular CS and neurological manifestations was compared with meta-analysis by RevMan 5.3 software.Results:Sixty-eight studies were initially retrieved according to the search strategy, and 17 studies were finally included, and 5 studies with CS+ and CS- were meta-analyzed. Among the 43 patients, 28 were male and 15 were female, with a median age of 12 years. Visual impairment was observed in 37 cases (90.2%, 37/41, 2 cases not recorded), and CS was present in 24 cases (55.8%, 24/43). The most common neurological manifestation was myoclonus (97.7%, 42/43), followed by cerebellar ataxia (95.1%, 39/41, 2 cases not recorded) and seizures (91.4%, 32/35, 8 cases not recorded). Pathogenic NEU1 gene mutations were detected in 42 cases and one case was undocumented. The incidence of seizure in group CS+ (100%, 20/20) was higher than that in group CS- (80%, 12/15). Meta-analysis showed that there was no statistically significant difference between the incidence of myoclonus or ataxia [relative risk ( RR)=1.13, 95% confidence interval ( CI) 0.79-1.63, P=0.49] and seizure ( RR=1.13, 95% CI 0.84-2.06, P=0.24) among the children in the CS+ and CS- groups. Conclusions:The incidence of ocular CS in Chinese children with type I SD was 55.8%. There was no correlation with neurological manifestations, however the incidence of seizure was significantly higher in patients with CS than in others without CS.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective:To investigate the carrier rate and clinical characteristics of epigenetic modification gene mutations (EMMs) among patients with acute myeloid leukemia (AML).Methods:One hundred seventy two patients who were initially diagnosed with AML at the First People′s Hospital of Lianyungang from May 2011 to February 2021 were selected as the study subjects. Next-generation sequencing was carried out to detect variants of 42 myeloid genes among these patients. Clinical and molecular characteristics of patients with EMMs and the effect of demethylation drugs (HMAs) on their survival were analyzed.Results:Among the 172 AML patients, 71 (41.28%) were found to harbor the EMMs, and carrier rates were TET2 (14.53%, 25/172), DNMT3A (11.63%, 20/172), ASXL1 (9.30%, 16/172), IDH2 (9.30%, 16/172), IDH1 (8.14%, 14/172), EZH2 (0.58%, 1/172). Patients with EMMs (+ ) had lower peripheral hemoglobin compared with those with EMMs (-) (72 g/L vs. 88 g/L, Z=-1.985, P<0.05). The proportion of EMMs(+ ) among elderly AML patients was significantly higher than that of young AML patients [71.11% (32/45) vs. 30.70% (39/127), χ2 = 22.38, P < 0.001]. EMMs (+ ) were significantly correlated with NPM1 gene variants ( r=0.413, P < 0.001), while negatively correlated with CEPBA double variants ( r=-0.219, P<0.05). Compared with conventional chemotherapy regimens, HMAs-containing chemotherapy regimens have improved the median progression-free survival (PFS) and median overall survival (OS) among intermediate-risk AML patients with EMMs (+ ) (PFS: 11.5 months vs. 25.5 months, P<0.05; 12.5 months vs. 27 months, P<0.05). Similarly, Compared with conventional chemotherapy regimens, chemotherapy with HMAs had increased median PFS and median OS in elderly AML patients with EMMs(+ ) (4 months vs. 18.5 months, P<0.05; 7 months vs. 23.5 months, P<0.05). Conclusion:Patients with AML have a high rate of EMMs carriage, and HMAs-containing chemotherapy regimens can prolong the survival of elderly patients with AML with poor prognosis, which may provide a reference for individualized treatment.

Backgrounds::GALLIUM is a global phase III study that demonstrated significant improvements in progression-free survival (PFS) for obinutuzumab plus chemotherapy (G-chemo) vs. rituximab plus chemotherapy (R-chemo) in previously untreated patients with follicular lymphoma (FL). This study aimed to report the results of a subgroup of patients in China. Methods::Patients were randomized to G-chemo or R-chemo. Responders received maintenance therapy for 2 years or until disease progression. The primary endpoint was investigator (INV)-assessed PFS. Secondary endpoints included the overall response rate (ORR) and complete response rate (CRR) at the end of induction chemotherapy, overall survival (OS), and safety.Results::Overall, 58 patients with FL were randomized to the G-chemo ( n = 25) and R-chemo arms ( n = 33). The INV-assessed PFS rate at 3 years was 81.8% in the G-chemo arm, vs. 70.2% in the R-chemo arm (hazard ratio 0.35; 95% confidence interval: 0.09-1.34; P = 0.1120). The INV-assessed CRRs (without positron emission tomography [PET]) in these arms were 24.0% and 21.2%, respectively, whereas the ORRs were 80.0% and 90.9%, respectively. INV-assessed CRR-PET was 52.6% in the G-chemo, vs. 60.9% in the R-chemo. Median OS was not reached in either arm. Grade 3 to 5 adverse events were more frequent in the R-chemo arm (97.0% vs. 88.0%). Conclusions::The results of this subgroup analysis were consistent with those of the global population, and they suggest that G-chemo has a positive benefit-risk profile in patients from China with FL.Trial registration::ClinicalTrials.gov, No. NCT01332968.

Objective:To investigate the effect of ultrasound-guided midline catheter placement on the incidence of catheter-related bloodstream infection (CRBSI) in severe emergency patients.Methods:Five hundred and twenty-nine patients were chosen as the research objects from March 2018 to December 2019 at Emergency Intensive Care Unit, which was divided into the experimental group ( n=278) and the control group ( n=251). In the experimental group, ultrasound-guided midline catheter was used as central venous catheter (CVC) removal method of sequential, and in the control group, peripheral venous indwelling needle was used as sequential method after removal of CVC. CVC, midline catheter and the indwelling time of indwelling needle were counted. The utilization rate of CVC was compared between the two groups. Kaplan-Meier survival curve was plotted to describe the CVC indwelling time of the two groups and log-rank test was performed. Cox regression analysis was performed to analyze the influencing factors of CVC indwelling time and compare the incidence of CRBSI and other catheter-related complications. Results:The CVC indwelling time of the experimental group was significantly shorter than that of the control group (8 d vs. 13 d, P=0.000). The CVC utilization rate of the experimental group was significantly lower than that of the control group (49.83% vs. 80.45%, P=0.000). Multivariate Cox regression analysis showed that difficult intravenous access, length of ICU stay, the site of catheter placement, and midline catheter implantation without ultrasound-guidance were independent risk factors for prolonged CVC indwelling time ( P=0.000). The CRBSI rate of the experimental group was significantly lower than that of the control group (0.571‰ vs. 3.802‰, P=0.038). There was no significant difference in the incidence of other catheter-related complications between the two groups ( P=0.403). Conclusions:Ultrasound-guided midline catheter implantation can shorten the indwelling time of CVC, reduce the utilization rate of CVC, and reduce the incidence of CRBSI, which is worthy of clinical promotion.
