Neuronal reprogramming is an innovative technique for converting non-neuronal somatic cells into neurons that can be used to replace lost or damaged neurons, providing a potential effective therapeutic strategy for central nervous system (CNS) injuries or diseases. Transcription factors have been used to induce neuronal reprogramming, while their reprogramming efficiency is relatively low, and the introduction of exogenous genes may result in host gene instability or induce gene mutation. Therefore, their future clinical application may be hindered by these safety concerns. Compared with transcription factors, small-molecule compounds have unique advantages in the field of neuronal reprogramming, which can overcome many limitations of traditional transcription factor-induced neuronal reprogramming. Here, we review the recent progress in the research of small-molecule compound-mediated neuronal reprogramming and its application in CNS regeneration and repair.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease with a high mortality rate. Many countries worldwide have already reported local transmission, and the number of reported cases has been increasing yearly, with an ever-expanding region. No specific treatment drugs or vaccines have seriously threatened public health safety in epidemic regions. This article reviews the epidemiological characteristics, transmission routes, and control measures of SFTS.

This study was aimed at analyzing the genomic characteristics of Salmonella typhimurium(1,4,[5],12:i:1,2)in Urumqi from 2018 to 2021,to provide evidence for the monitoring of this serotype and handling of public health emergen-cies.A total of 26 Salmonella typhimurium isolates were obtained from the feces of people with diarrhea in Urumqi.Whole-genome sequencing(WGS)combined with bioinformatic analysis was used to predict serovars,MLST types,plasmid repli-cons,antimicrobial resistance genes,and virulence genes;in addition phylogenomic analysis based on genome-wide single nucleotide polymorphisms(wgSNPs)was conducted to determine the epidemiological relatedness among isolates.A total of 47 resistance genes representing ten categories were de-tected with a high prevalence,including aac(6')-Iaa(100％),blaTEM-1B(30.8％),tet(A)(42.3％),qnrS1(30.8％),and sul3(23.1％),encoding resistance to aminoglycosides,β-lac-tams,tetracyclines,quinolones,and sulfa,in addition to chro-mosomic mutations affecting the gyrA gene.Moreover,12 plasmids were detected,among which IncFIB(S)and IncFII(S)(34.6％)were dominant.The differences in virulence genes a-mong strains isolated in different periods were reflected primarily in the typical virulence genes associated with Salmonella vir-ulence mechanisms.In addition,cgMLST indicated that the dominant type of Salmonella typhimurium was cgST36414,con-tainning 10 strains.Moreover,wgSNP analysis indicated that Salmonella typhimurium isolates in Urumqi were consistent with the epidemic trends in 15 provinces and cities in China and also showed local evolution.Salmonella typhimurium isolates in Urumqi frequently carried a variety of resistance genes and plasmid replicons,which are key in the dissemination and evolution of drug resistance.Close communication links may exist with various sources of flora in the food chain,thus posing severe chal-lenges in public health monitoring and prevention.Therefore,the construction of the laboratory routine monitoring network based on internet information systems should be strengthened to improve the timeliness of monitoring and limit the spread of multidrug-resistant strains.

Gambogic acid, a caged xanthone compound derived from Garcinia, has been proven to be an important substance basis for the pharmacological effects of the plant. In recent years, it has received continuous attention due to its broad and significant pharmacological activities. Modern pharmacological investigations have demonstrated that gambogic acid endows various therapeutic effects such as anti-inflammatory, antioxidant, and anti-tumor activities, as well as benefits in retinopathy, organ protection, anti-microbial infection, bone protection, and neuropathic pain relief. Nevertheless, there is currently a lack of systematic summary and integration of the pharmacological effects and mechanisms of gambogic acid, which is critical for advancing the clinical application of this natural product. In addition, current research has raised concerns about potential safety risks associated with gambogic acid, such as organ toxicity, developmental toxicity, and hemolysis. Given this, this paper systematically reviewed and summarized the pharmacological effects, mechanisms, and toxicological profiles of gambogic acid, aiming to provide reference and data support for its clinical translation.

Objective: To explore the stem cell collection rate and efficacy and safety of patients aged 70 and below with newly diagnosed multiple myeloma (MM) treated with the VRD (bortezomib, lenalidomide and dexamethasone) regimen followed by autologous stem cell transplantation (ASCT). Methods: Retrospective case series study. The clinical data of 123 patients with newly diagnosed MM from August 1, 2018, to June 30, 2020, at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematology Hospital, who were eligible for VRD regimen sequential ASCT, were collected. The clinical characteristics, efficacy after induction therapy, mobilization regimen of autologous stem cells, autologous stem cell collection rate, and side effects and efficacy of ASCT were retrospectively analyzed. Results: Of the 123 patients, 67 were males. The median patient age was 56 (range: 31-70) years. Patients with IgG, IgA, IgD, and light-chain types accounted for 47.2% (58/123), 23.6% (29/123), 3.2% (4/123), and 26.0% (32/123) of patients, respectively. In addition, 25.2% (31/123) of patients had renal insufficiency (creatinine clearance rate<40 ml/min). Patients with Revised-International Staging System (R-ISS) Ⅲ accounted for 18.2% (22/121) of patients. After induction therapy, the rates of partial response and above, very-good partial response (VGPR) and above, and complete response (CR)+stringent CR were 82.1% (101/123), 75.6% (93/123), and 45.5% (56/123), respectively. Overall, 90.3% (84/93) of patients were mobilized with cyclophosphamide+granulocyte colony-stimulating factor (G-CSF) and 8 patients with G-CSF or G-CSF+plerixafor due to creatinine clearance rate<30 ml/min and one of them was mobilized with DECP (cisplatin, etoposide, cyclophosphamide and dexamethasone)+G-CSF for progressive disease. The rate of autologous stem cell collection (CD34⁺cells≥2×10⁶/kg) after four courses of VRD regimen was 89.1% (82/92), and the rate of collection (CD34⁺cells≥5×10⁶/kg) was 56.5% (52/92). Seventy-seven patients treated with the VRD regimen sequential ASCT. All patients had grade 4 neutropenia and thrombocytopenia. Among the nonhematologic adverse events during ASCT, the highest incidence was observed for gastrointestinal reactions (76.6%, 59/77), followed by oral mucositis (46.8%, 36/77), elevated aminotransferases (44.2%, 34/77), fever (37.7%, 29/77), infection (16.9%, 13/77) and heart-related adverse events (11.7%, 9/77). Among the adverse events, grade 3 adverse events included nausea (6.5%, 5/77), oral mucositis (5.2%, 4/77), vomiting (3.9%, 3/77), infection (2.6%, 2/77), elevated blood pressure after infusion (2.6%, 2/77), elevated alanine transaminase (1.3%, 1/77), and perianal mucositis (1.3%, 1/77); there were no grade 4 or above nonhematologic adverse events. The proportion of patients who achieved VGPR and above after VRD sequential ASCT was 100% (75/75), and the proportion of patients who were minimal residual disease-negative (<10^-4 level) was 82.7% (62/75). Conclusion: In patients aged 70 and below with newly diagnosed MM treated with VRD induction therapy, the collection rate of autologous stem cells was good, and good efficacy and tolerability were noted after follow-up ASCT.

Objective: To understand the prevalence of chronic kidney disease (CKD) and related factors in adults in Anhui province based on the data of Chinese Chronic Diseases and Nutrition Surveillance program (2018) in Anhui. Methods: Multi-stage stratified cluster random sampling was used to select participants aged ≥18 years. Moreover, questionnaire survey, body measurements and laboratory tests were conducted. The complex weighting method was used to estimate the prevalence of CKD in residents with different characteristics, and complex sampling data logistic regression model was used for multivariate analysis to identify related risk factors. Results: A total of 7 181 participants were included. The overall prevalence of CKD was 11.06% in adults in Anhui, and the prevalence was 12.49% in women and 9.59% in men (P<0.05). The moderate, high and very high risk for CKD progression were 8.66%, 2.02% and 0.38%, respectively. Multivariate analysis showed that age (OR=1.03, 95%CI: 1.00-1.05), BMI (OR=1.05, 95%CI: 1.01-1.09), being woman (OR=1.38,95%CI: 1.22-1.55), hypertension (OR=2.50, 95%CI: 1.76-3.56), diabetes (OR=2.28, 95%CI: 1.51-3.43), dyslipidemia (OR=1.26, 95%CI: 1.11-1.43) and hyperuricemia (OR=2.16, 95%CI: 1.68-2.78) were risk factors for CKD. Conclusion: The prevalence of CKD in adults in Anhui was relatively high and age, gender, BMI, hypertension, diabetes, dyslipidemia and hyperuricemia were found to be associated with the prevalence of CKD. To prevent CKD and its complications, attention should be paid to the management of related risk factors, including overweight and obesity, hypertension, diabetes, dyslipidemia and hyperuricemia.

Objective: To analyze the clinical characteristics, treatment response, and prognosis of newly diagnosed symptomatic multiple myeloma (MM) patients with systemic light chain amyloidosis (AL) . Methods: The clinical data of 160 patients with newly diagnosed MM treated at the First Affiliated Hospital of Soochow University from January 1, 2017 to October 31, 2018, were retrospectively analyzed. According to the histopathological biopsy results of bone marrow, skin, and other tissues, the patients were divided into two groups according to whether amyloidosis was combined or not, namely, the MM+AL group and the MM group. The clinical characteristics and treatment responses of the two groups were compared. Results: Among the 160 patients with newly diagnosed MM, there were 42 cases in the MM+AL group and 118 cases in the MM group. In terms of clinical features, the involved light chain and non-involved light chain (dFLC) in the MM+AL group was significantly higher than that in the MM group (P=0.039) . After induction treatment, the MM+AL group had a higher overall response rate (85.7%vs 79.7%, P<0.05) and higher excellent partial response (76.2%vs 55.1%, P<0.05) . After a median follow-up of 26 (0.25-41) months, there was no significant difference in the progression free survival and overall survival (OS) between the two groups (P>0.05) . The OS of patients in autologous hematopoietic stem cell transplantation group was better than that in non transplantation group (P<0.05) .The prognosis of patients with cardiac involvement in the MM+AL group was significantly worse than that in the MM group and MM+AL group without cardiac involvement (P<0.001) , with a median OS of only 13 months. Conclusion: The differential diagnosis between the MM+AL and MM groups requires histopathology, particularly for patients with significantly increased dFLC. The overall remission rate of patients in MM+AL group after 4 courses of induction chemotherapy was higher than that in MM group. The prognosis of patients with cardiac involvement in MM+AL group was poor.
