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.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective:To explore the clinical effect of composite skin transplantation combined with systemic rehabilitation in the treatment of extensive scar contracture deformity around the popliteal fossa in children after burns.Methods:A retrospective observational research method was adopted. Seventeen children with extensive scar contracture deformities around the popliteal fossa after burns who met the inclusion criteria and were admitted to the First Affiliated Hospital of Air Force Military Medical University from March 2018 to April 2022 were selected. Among them, there were 10 males and 7 females, aged 2-11 years, with scar contracture deformities lasting from 10 months to 9 years, all located around the popliteal fossa, 10 cases of right popliteal fossa, 5 cases of left popliteal fossa, 2 cases of bilateral popliteal fossa, scars around the popliteal fossa result in a knee joint extension angle of only 95° to 115°. The scar contracture during surgery was thoroughly released, joint mobility was restored, so as to form a secondary wound range of 10 cm×8 cm-20 cm×13 cm. In stage Ⅰ, after completely releasing the scar contracture, the wound was covered with negative pressure closure drainage (VSD) for 2-3 days. In stage Ⅱ, a large autologous blade thick scalp and allogeneic decellularized dermal matrix composite graft was performed to repair the wound around the popliteal fossa. After 8-10 days of surgery, the dressing was changed to check the survival of the skin graft. One week after the skin graft survived, a 12 month orderly knee joint function training was conducted under the guidance of a rehabilitation therapist. Postoperative sequential treatment with a combination of strong pulsed light and ultra pulsed carbon dioxide lattice laser for 5-7 courses of significant scar hyperplasia in the skin graft area and edges.Results:15 cases of pediatric patients had good skin graft survival; One patient developed a wound due to partial displacement of the transplanted autologous scalp, and one patient developed a plasma swelling under the limb graft, which was drained through an opening. Two patients underwent dressing changes for 3 weeks before the wound healed. After follow-up for 6 to 36 months, the elasticity and appearance of the skin graft were similar to those of a medium thickness skin graft. Children with knee joint contracture were able to fully extend to 180°, and knee joint function was significantly improved. There was no scar formation or hair loss in the donor skin area.Conclusions:The combination of composite skin transplantation and systematic rehabilitation has a good effect on the treatment of extensive scar contracture around the popliteal fossa in children after burns, avoiding the problem of scars left in the donor area due to autologous skin grafting.
