Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

OBJECTIVES: To explore potential keywords, research clusters, collaborative pattern, and research trends in the field of medical technology management (MTM) through bibliometric analysis, providing insights for researchers, policy makers, and hospital administrators. METHODS: A retrieval formula was applied to the title, abstract, and keywords in the Web of Science (WoS) Core Collection, along with system-recommended terms, to identify articles on MTM. A total of 181 articles published between 1974 and 2022 were retained for quantitative analysis. The global trend of research output; total citations, average citations, and H-index; and bibliographic coupling, co-authorship, and keyword co-occurrence were analyzed using VOSviewer. RESULTS: The number of articles on MTM has been steadily increasing year by year. The focus of research has shifted from addressing basic medical needs to prioritizing emergency response and medical information security. The United States, Italy, and the United Kingdom emerged as the main contributors, with the United States leading in both volume of publications (60 articles) and academic impact (H-index = 21). Authors from the United Kingdom and the United States led the way in cross-border cooperation. The top five institutions, ranked by total link strength among cross-institutional authors, were primarily located in Canada and Spain. CONCLUSIONS The field of MTM has experienced stable growth over the past three decades (1993-2022). The shift of research focus has prompted a heightened emphasis on protecting patient privacy and ensuring the security of medical data. Future research should emphasize interdisciplinary and professional collaboration, as well as international cooperation and open sharing of knowledge.

OBJECTIVE: To investigate the clinical characteristics, treatment and prognosis of adult AML patients with NUP98::HOXA9 fusion gene. METHODS: From May 2017 to October 2023， among 2 113 AML patients who visited the Hematology Department of our hospital, patients with NUP98 rearrangements were screened. The clinical characteristics, chromosome karyotypes, immunophenotypes, gene mutations, treatment efficacy and prognosis of the patients with NUP98::HOXA9 positive were analyzed. RESULTS: Among the 2 113 AML patients, there were 18 cases with NUP98 rearrangement, including 14 NUP98::HOXA9 positive cases, with a detection rate of 0.66% (14/2 113). The median age of the NUP98::HOXA9 positive patients was 42.5 (23-64) years old. The most common chromosome karyotype was t(7; 11)(p15; p15). The immunophenotypes of all patients expressed CD13, CD33, CD117 and CD38, and most patients expressed CD34 and cMPO, while only a few expressed HLA-DR. Second-generation sequencing (NGS) was performed to detect genetic mutations associated with leukemia in all 14 patients, and the genes exhibiting a high frequency of mutation were WT1 (10/14), TET2 (7/14), and FLT3-ITD (6/14). Additionally, mutations were also observed in KRAS/NRAS, IDH1, and KIT. Of the 13 patients who received treatment, 9 achieved complete remission (CR), and all 3 patients who received azacytidine(AZA)+ venetoclax (VEN) regimen achieved CR after the first course of treatment. Within this cohort, 6 patients were classified as relapsed/refractory (6/13). 4 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), of which two achieved long-term survival. The median follow-up time was 12 (2.1-65.0) months, while the median overall survival (OS) and relapse-free survival (RFS) were recorded as 11.4 months and 9.6 months, respectively. CONCLUSION The most common type of NUP98 rearrangement in adults AML patients is NUP98::HOXA9 , which is often accompanied by somatic mutations in WT1, TET2, and FLT3-ITD. These patients are prone to relapse, have short survival time, and generally face poor prognoses. Hopefully, utilization of the AZA+VEN regimen is anticipated to enhance the rate of induced remission in the patients, and some patients may prolong their survival through allo-HSCT. However, more effective treatment methods are still needed to improve the overall prognosis of these patients.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

OBJECTIVE To explore the short-term efficacy,safety and related influencing factors of subcutaneous immunotherapy(SCIT)in children with allergic rhinitis(AR).METHODS Retrospective analyzed the clinical data of 147 children with AR who underwent SCIT at Shenzhen Hospital of Southern Medical University from August 2020 to May 2024.The clinical characteristics and laboratory parameters were collected,the visual analogue scale(VAS),total symptom score(TSS),total medication score(TMS)and combined symptom medication score(CSMS)were compared at the baseline and 3,6 and 12 months after treatment.The incidence of local adverse reactions(LRs)and systemic adverse reactions(SRs)during treatment was also documented.RESULTS A total of 147 children with AR aged 5-18 years were included in the study.A significant reduction was observed in VAS,TSS,TMS and CSMS at months 3,6 and 12 of follow up compared with baseline(all P<0.001),and the short-term onset time was months 3 after treatment.The level of VitD3 in the effective group was significantly higher than that in the ineffective group(P<0.001).Serum VitD3 level was negatively correlated with clinical symptom(R=-0.3,P=0.026).The total number of injections in 147 children was 3201.LRs occurred in 52 children(35.4％),the number of injections was 69(2.2％).SRs occurred in 21 children(14.3％),and the number of injections was 34(1.1％).No grade Ⅲ or Ⅳ SRs occurred.In the logistic regression analysis,body mass index(BMI)was a risk factor for LRs(OR:2.220,95％CI:1.009-4.887,P=0.048).CONCLUSION SCIT demonstrates significant early efficacy and a favorable safety profile safety in children with AR.Serum Vitamin D3 deficiency can affect the short-term efficacy of SCIT.Overweight and obese children are prone to develop local adverse reactions.

Objective This study aimed to provide an effective scientific basis for prevention and control of cockroaches on aircrafts by identifying cockroach-carried pathogens,and assess the insecticidal efficacy of gel bait mediated cockroach control on aircrafts,to provide technical guidance for aircraft disinsection.Methods Cassette-trapping was used to trap cockroaches,and the carried pathogens were detected using bacterial cultivation techniques.The gel bait mediated killing rate was calculated after 1,7,and 30 d by field application of gel bait.Results A total of 411 cockroaches were captured,and all were identified as Blattella germanica.26 strains of pathogenic bacteria were isolated from the trapped cockroaches.The killing rates of cockroaches were 58.8％-96.3％with 1-30 day application of gel bait.Statistically significant differences were observed in cockroach killing rates on different days(χ2=58.95,P<0.01).Conclusions B.germanica carry a large variety of pathogenic bacteria and opportunistic pathogens and are thus important infectious disease carriers.Gel bait agents have proven to be very effective against cockroaches on aircrafts.

Bone morphogenetic proteins are a large subclass of the transforming growth factor β family,and Their signaling pathways are mainly classified into two kinds based on whether they depend on Smad protein to mediate or not.BMP signaling pathways are involved in regulating cell proliferation and differentiation,as well as the formation and development of multiple tissues and organs.Recent studies have shown that BMP signaling path-ways mainly promote the differentiation and growth of neurons and astrocytes,and are closely related to the my-elination of oligodendrocytes.In addition,BMP signaling pathways also play an important role in the occurrence of central nervous system diseases,such as spinal cord injuries,multiple sclerosis,neural tube defects,and Parkin-son's disease.This article reviews the BMP signaling pathways'composition,transduction mechanism and their role in the central nervous system and related diseases,in order to provide more potential ideas for basic research and clinical treatment of central nervous system diseases.

Objective:The study aimed to validate the Neuroception of Psychological Safety Scale (NPSS) in terms of reliability and validity among individuals with mental disorders in China.Methods:The Study followed Brislin′s translation principles to adapt the scale into Chinese. From February to June 2023, a total of 638 hospitalized patients with mental disorders (477 with schizophrenia and 161 with mood disorders) were selected through gender-stratified simple random sampling from the Shanghai Pudong New Area Mental Health Center and the Shanghai Baoshan Mental Health Center. The Chinese version of the NPSS and the Security Questionnaire (SQ) were administered. The reliability of the scale was measured using split-half reliability and test-retest reliability. Validity was assessed through content validity, structural validity, convergent validity, and discriminative validity analyses. In addition, SQ was used as a criterion tool to test the validity of the criterion through Pearson correlation analysis.Results:The Chinese version of the NPSS contained 29 items, with total scores ranging from 29 to 145. Higher total scores indicated greater psychological safety. Item analysis showed a decider value of 10.58 to 20.80 (>3), and the correlation between items and total scores ranged from 0.579 to 0.749 (all P<0.05). The item-level content validity index (I-CVI) for the items ranged from 0.86 to 1.00, while the average scale-level content validity index (S-CVI/Ave) was 0.99. Exploratory factor analysis extracted three common factors: social participation, empathy, and bodily sensations, which is consistent with the structure of the original scale, explaining a cumulative variance contribution rate of 62.551%. Confirmatory analysis revealed a satisfactory model fit, with average variance extracted (AVE) values for the three dimensions ranging from 0.523 to 0.645, and composite reliability(CR) ranging from 0.905 to 0.938. The standard loading coefficients for the items ranged from 0.608 to 0.859, and inter-factor correlation coefficients were all smaller than the square roots of their respective AVE values. Pearson correlation analysis indicated significant positive relationships between the Chinese NPSS and SQ ( r=0.822-0.846, P<0.01). Reliability analysis showed Cronbach′s alpha coefficients of 0.903-0.959 for the total scale and subscales. After a 3-week interval, test-retest reliability (70 patients) ranged from 0.874 to 0.983, and split-half reliability was 0.869-0.969. All model fit indices met established criteria. Conclusions:The Chinese version of the NPSS demonstrates good reliability and validity, making it suitable for both research and clinical applications in assessing psychological security among individuals with schizophrenia and mood disorders.
