ObjectiveTo observe the clinical efficacy and safety of Chaihu Shugansan combined with Xuanfu Daizhetang (CHSG-XFDZ) in the management of Barrett's esophagus (BE) with liver-stomach disharmony. MethodA randomized, parallel, controlled, double-blind clinical trial was conducted. BE patients who met the inclusion criteria were randomized into an observation group and a control group, with 34 patients in each group. The observation group was treated with CHSG-XFDZ combined with omeprazole capsules, and the control group was treated with CHSG-XFDZ mimetic combined with omeprazole capsules. Both groups were treated for 12 weeks. The traditional Chinese medicine (TCM) symptom scores, response rate, BE lesion area, BE pathological changes, and bile acid profile were taken as the indicators to jointly evaluate the clinical efficacy and safety of the two groups. ResultA total of 62 patients who completed the trial were included for statistical analysis, including 32 in the observation group and 30 in the control group. There were no statistically significant differences in baseline demographics or disease characteristics between two groups, which suggested that the two groups were comparable. The total response rate in the observation group was 93.7% (30/32), which was higher than that (60.0%, 18/30) in the control group (χ2=24.766, P<0.05). After treatment, the response rate regarding the pathological changes in the observation group was 62.5% (20/32), which was higher than that (23.3%, 7/30) in the control group (χ2=10.270, P<0.05). The response rate regarding the BE lesion area change in the observation group was 21.9% (7/32), which had no statistically significant difference from that (6.7%, 2/30) in the control group, which indicated that the advantages of the two regimens were not obvious in terms of reducing the area of BE lesions. Compared with the control group after treatment, the observation group regulated the bile acid profile, which pointed out the direction for further exploring the mechanism of CHSG-XFDZ in treating BE. Neither group showcased adverse reactions with clinical significance during the treatment period. ConclusionCHSG-XFDZ outperformed the control group in terms of alleviating TCM symptoms, ameliorating pathological changes, and improving the bile acid profile in the BE patients with liver-stomach disharmony. It demonstrates certain potential in reducing the lesion area. This formula is safe and effective in treating BE patients with liver-stomach disharmony and deserves further clinical research and widespread application.

The seat of human intelligence is the human cerebral cortex, which is responsible for our exceptional cognitive abilities. Identifying principles that lead to the development of the large-sized human cerebral cortex will shed light on what makes the human brain and species so special. The remarkable increase in the number of human cortical pyramidal neurons and the size of the human cerebral cortex is mainly because human cortical radial glial cells, primary neural stem cells in the cortex, generate cortical pyramidal neurons for more than 130 days, whereas the same process takes only about 7 days in mice. The molecular mechanisms underlying this difference are largely unknown. Here, we found that bone morphogenic protein 7 (BMP7) is expressed by increasing the number of cortical radial glial cells during mammalian evolution (mouse, ferret, monkey, and human). BMP7 expression in cortical radial glial cells promotes neurogenesis, inhibits gliogenesis, and thereby increases the length of the neurogenic period, whereas Sonic Hedgehog (SHH) signaling promotes cortical gliogenesis. We demonstrate that BMP7 signaling and SHH signaling mutually inhibit each other through regulation of GLI3 repressor formation. We propose that BMP7 drives the evolutionary expansion of the mammalian cortex by increasing the length of the neurogenic period.

Objective:To summarize the clinical features associated with respiratory syncytial virus (RSV) infection in patients following the hematopoietic stem cell transplant (HSCT) and exploring the risk factors for death.Methods:Patients who had RSV infection after undergoing HSCT from October 2023 to January 2024 in the hematology department of Peking University People’s Hospital were enrolled in the study. The clinical characteristics of the participating patients were summarized. The clinical characteristics of the surviving and the dying patients were compared, and the risk factors of death were analyzed by binary logistic regression.Results:Among the 43 RSV-positive HSCT patients, 20 (46.5%) were hypoxemic, six (14.0%) were admitted to the ICU for further treatment, four (9.3%) required tracheal intubation assisted ventilation, and seven patients (16.3%) died. A comparison of the clinical features of the surviving patients and the deceased patients demonstrated that the deceased patients had a lower PLT when infected with RSV [74.5 (8.0-348.0) ×10 9/L vs 15.0 (10.0-62.0) ×10 9/L, P=0.003], a higher incidence of simultaneous bacterial infections (85.7% vs 41.7%, P=0.046), and a higher rate of hematological recurrence (71.4% vs 13.9%, P=0.004). Hematological recurrence ( OR=15.500, 95% CI 2.336-102.848, P=0.005), influenza A viral infection ( OR=14.000, 95% CI 1.064-184.182, P=0.045), and low PLT at the time of RSV infection ( OR=0.945, 95% CI 0.894-0.999, P=0.048) were the factors associated with death following HSCT. Conclusion:Patients infected with RSV after undergoing HSCT have a poor prognosis, and active prevention and treatment of RSV in the autumn and winter requires urgent attention.

Objective:To explore the efficacy of central combined peripheral dual-target magnetic stimulation on Parkinson disease (PD) patients with freezing of gait (FOG).Methods:A total of 39 patients with FOG diagnosed at the Parkinson disease clinic of the Affiliated Hospital of Nantong University were included in the study from July 2022 to September 2023.They were randomly divided into observation group ( n=20) and control group ( n=19) by the random number table method. The patients in control group were treated with repetitive transcranial magnetic stimulation (rTMS), while the patients in observation group were treated with additional repetitive peripheral magnetic stimulation(rPMS) on the affected tibialis anterior muscle on the basis of the control group. Other clinical medical treatments were the same for both groups of patients.The timed up and go test (TUGT), 10 meter walk test (10MWT), and motor evoked potentials (MEP) were used to evaluate the efficacy before and after 2 weeks of treatment.The SPSS 25.0 software was used for statistical analysis. Independent sample t-test was used for comparison between the two groups, and paired sample t-test was used for comparison before and after treatment within group. Results:Before treatment, there were no statistically significant difference in TUGT time, 10MWT speed and MEP amplitude between the two groups( t=0.659, 0.514, 0.345, all P>0.05).After treatment, the TUGT time((7.87±1.74) s vs (9.31±1.57)s)and MEP amplitude((41.59±14.81)mV vs (58.26±19.26) mV)of the observation group were lower than those of the control group( t=2.723, 3.039, P=0.010, 0.004), while the 10MWT speed of the observation group was higher than that of the control group ((1.21±0.20) m/s vs (1.01±0.17)m/s, t=3.173, P=0.003).After treatment, the TUGT time and MEP amplitude of patients in the observation group and control group were all lower than before treatment (observation group: t=13.512, 7.126, both P<0.001; control group: t=6.535, 3.094, both P<0.05). The 10MWT speeds of patients in the observation group and control group after treatment were both higher than before treatment ( t=25.665, 6.750, both P<0.001). Conclusion:The combination of central and peripheral dual-target magnetic stimulation may improve the FOG of PD patients, and it is worthy of clinical promotion.

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group, model group, positive control group (27 mg/kg allopurinol+0.27 mg/kg colchicine), Tongfeng li’an capsules low- dose, medium-dose and high-dose groups (2.2, 4.5, 9.0 g/kg), with 10 rats in each group. Except for normal group, gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically, and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling, serum level of interleukin-1β (IL-1β) and protein expressions of nuclear factor kappa-B (NF-κB) in synovial tissue were detected, and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules (62.5, 125, 250 μg/mL) were given, the levels of nitric oxide (NO), reactive oxygen species (ROS) and IL-1β in the cells and protein expression of NF-κB were detected, and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group, the swelling degree of the ankle joint, serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group (P<0.05); pathological changes such as synovial hyperplasia, edema, vascular congestion, capillary hyperplasia, and increased inflammatory cells were observed. Compared with model group, the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group (P<0.05), and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups (P<0.05); synovial hyperplasia of the ankle joint improved, and the infiltration of inflammatory cells 2019BS044) decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO, ROS and IL-1β and protein expression of NF-κB(P<0.01), and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis, and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.

Human cortical radial glial cells are primary neural stem cells that give rise to cortical glutaminergic projection pyramidal neurons, glial cells (oligodendrocytes and astrocytes) and olfactory bulb GABAergic interneurons. One of prominent features of the human cortex is enriched with glial cells, but there are major gaps in understanding how these glial cells are generated. Herein, by integrating analysis of published human cortical single-cell RNA-Seq datasets with our immunohistochemistical analyses, we show that around gestational week 18, EGFR-expressing human cortical truncated radial glial cells (tRGs) give rise to basal multipotent intermediate progenitors (bMIPCs) that express EGFR, ASCL1, OLIG2 and OLIG1. These bMIPCs undergo several rounds of mitosis and generate cortical oligodendrocytes, astrocytes and olfactory bulb interneurons. We also characterized molecular features of the cortical tRG. Integration of our findings suggests a general picture of the lineage progression of cortical radial glial cells, a fundamental process of the developing human cerebral cortex.

Whether Fanconi anemia (FA) heterozygotes are predisposed to bone marrow failure and hematologic neoplasm is a crucial but unsettled issue in cancer prevention and family consulting. We retrospectively analyzed rare possibly significant variations (PSVs) in the five most obligated FA genes, BRCA2, FANCA, FANCC, FANCD2, and FANCG, in 788 patients with aplastic anemia (AA) and hematologic malignancy. Sixty-eight variants were identified in 66 patients (8.38%). FANCA was the most frequently mutated gene (n = 29), followed by BRCA2 (n = 20). Compared with that of the ExAC East Asian dataset, the overall frequency of rare PSVs was higher in our cohort (P = 0.016). BRCA2 PSVs showed higher frequency in acute lymphocytic leukemia (P = 0.038), and FANCA PSVs were significantly enriched in AA and AML subgroups (P = 0.020; P = 0.008). FA-PSV-positive MDS/AML patients had a higher tumor mutation burden, higher rate of cytogenetic abnormalities, less epigenetic regulation, and fewer spliceosome gene mutations than those of FA-PSV-negative MDS/AML patients (P = 0.024, P = 0.029, P = 0.024, and P = 0.013). The overall PSV enrichment in our cohort suggests that heterozygous mutations of FA genes contribute to hematopoietic failure and leukemogenesis.

Objective:To investigate the value of minimal residual disease (MRD) in prediction of prognosis in acute lymphoblastic leukemia (ALL) patients with or above complete remission 2 (CR2) underwent.Methods:A retrospective analysis was performed on 201 ALL patients who received allogeneic stem cell transplantation (allo-SCT) and pretransplant disease status ≥CR2 in Peking University People′s Hospital from January 2009 to December 2018. MRD was measured by multi-parameter flow cytometry at 1 month before transplantation and 1 month, 2 months, 3 months, 4 months, 6 months, 9 months or 12 months after transplantation. To investigate the influence of dynamic changes of MRD before and after transplantation on prognosis.Results:201 ALL patients, including 126 males and 75 females, with a median age of 18 years. The 3-year cumulative incidence of relapse (CIR), non-relapse mortality (NRM), leukemia-free survival (LFS) and overall survival (OS) of all cases were 34%, 16%, 50%, and 56%, respectively. Positive pre-SCT MRD patients with higher 3-year CIR (47% vs 26%, P=0.003), lower 3-year LFS (40% vs 55%, P=0.047) and OS (42% vs 60%, P=0.065) than those with negative one. Subjects with positive post-MRD had higher 3-year CIR (73% vs 22%, P<0.001) and lower 3-year LFS (28% vs 56%, P=0.005) and OS (32% vs 60%, P=0.040) compared with those with negative one. Multivariate analysis showed that both pre-MRD and post-MRD were associated with higher CIR ( HR=1.823, P=0.018; HR=3.474, P<0.001), lower LFS ( HR=1.779, P=0.007; HR=2.185, P=0.001) and OS ( HR=1.609, P=0.034; HR=1.970, P=0.001). Negative pre-and post-SCT MRD group had lower 3-year CIR (17%, 42%, 82%; P<0.001) and higher 3-year LFS (61%, 44%, 18%; P<0.001) and OS (63%, 47%, 27%; P<0.001) compared with those unrisen post-SCT MRD group, and increased post-SCT MRD group. Multivariate analysis showed that pre-and post-SCT MRD dynamics were associated with CIR, LFS and OS ( P<0.01 for all) independently. The pre-and post-SCT MRD dynamics could better distinguish CIR (C=0.669) from that of pre-SCT MRD (C=0.587) and post-SCT MRD (C=0.629). Conclusion:Our data suggest that pre-SCT MRD, post-SCT MRD and the dynamic peri-SCT MRD could be used to predict transplant outcome of ALLpatients with or above CR2 who underwent allo-SCT.
