OBJECTIVE To identify and analyze adverse drug event （ADE） signals associated with tirzepatide based on the FDA Adverse Event Reporting System （FAERS） database， providing a reference for clinical medication safety. METHODS ADE reports from January 1， 2022， to June 30， 2024， with tirzepatide as the primary suspected drug， were extracted from the FAERS database. Medical Dictionary for Regulatory Activities was used to systematically categorize the selected system organ class （SOC） and preferred term of ADE. Signal mining and analysis were performed using the reporting odds ratio method and the proportional reporting ratio method. RESULTS A total of 39 229 ADE reports related to tirzepatide were obtained， including 3 934 severe ADE reports （10.03%）. The majority of severe ADE reports were related to hospitalization or prolonged hospitalization （3.82%）， involving 131 positive ADE signals. Among the reports with documented patient gender and age， 26 195 were female （66.77%）， 7 869 were male （20.06%）， and the majority of patients were aged 18-64 years （54.26%）. The top three most frequently reported ADE were injection site pain， nausea， and injection site hemorrhage. Strong ADE signals not mentioned in the tirzepatide instruction included injection site coldness， starvation ketoacidosis， injection site hemorrhage， hunger， elevated adrenaline， injection site skin cracking， binge eating， skin laxity， intestinal sepsis， lack of satiety， and dysesthesia. Subgroup analysis for patient’s gender and age showed differences in the proportion of ADE reports across different SOC. Male patients or those aged≥65 years had a higher risk of gastrointestinal system disorders compared to female patients or those aged ＜65 years. CONCLUSIONS In clinical use of tirzepatide， in addition to monitoring ADE listed in the instruction， attention should also be paid to ADE not mentioned in the instruction， such as injection site coldness， starvation ketoacidosis， injection site hemorrhage， elevated adrenaline， and intestinal sepsis， to ensure patient safety.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of tirzepatide for diabetes mellitus type 2 （T2DM） and long-term weight management， and provide evidence-based basis for clinical drug treatment and health insurance policy formulation. METHODS Computer searches were conducted in Embase， PubMed， the Cochrane Library， CNKI and health technology assessment （HTA） official website from their inception to October 1st 2024 to collect HTA report， systematic review/ meta-analysis and pharmacoeconomic study on tirzepatide for the treatment of T2DM or for weight management. After data extraction and quality evaluation， descriptive analysis was performed on the research results. RESULTS Totally 18 papers were included， including 14 systematic reviews/meta-analyses and 4 pharmacoeconomics studies， and no HTA report was retrieved. In terms of efficacy， most results showed that the tirzepatide 10 mg and 15 mg were significantly better than other glucagon-like peptide-1 （GLP-1） receptor agonists in reducing glycosylated hemoglobin， body weight， and waist circumference （P＜0.05）. In terms of safety， compared with other GLP-1 receptor agonists， tirzepatide did not increase the incidence of gastrointestinal-related adverse events （AE）， the incidence of AE of grade ≥3， or the incidence of severe hypoglycemia （P＞0.05）. However， tirzepatide 15 mg may significantly increased the incidence of hypoglycemia and the rate of discontinuation due to adverse reactions （P＜ 0.05）. In terms of cost-effectiveness， based on the background of foreign pharmacoeconomic studies， tirzepatide was more cost- effective compared to semaglutide and liraglutide in the treatment of T2DM or for weight management. CONCLUSIONS Tirzepatide at doses of 10 mg and 15 mg has good efficacy and safety for the treatment of T2DM and for long-term weight management. However， when using the 15 mg dose of tirzepatide， close monitoring is required due to the risk of hypoglycemia and discontinuation due to adverse reactions it may pose. Based on pharmacoeconomic studies conducted abroad results， tirzepatide exhibits economic advantages.

Objective To analyze the diagnostic efficacy and clinical significance of magnifying endoscopy combined with narrow-band imaging(ME-NBI),acetate-indigo rouge staining and multi-slice spiral CT for early gastric cancer and precancerous lesions.Methods 202 patients with suspected early gastric cancer and precancerous lesions from February 2019 to March 2022 were regarded as the subjects of this study,all the patients underwent ME-NBI,acetate-indigo rouge staining,and multi-slice spiral CT examination;The diagnostic value of different examination methods for early gastric cancer and precancerous lesions was analyzed using the receiver operator characteristic curve(ROC curve),using the pathological results of gastric cancer as the gold standard,the diagnostic value of ME-NBI,acetate-indigo rouge staining combined with multi-slice spiral CT and their combination in early gastric cancer and precancerous lesions was analyzed using a four grid table.Results The image quality of ME-NBI and acetate-indigo rouge staining combined examinations was significantly higher than that of their respective independent examinations(P<0.05).There was significant difference in the degree of differentiation in the clinical features of patients with early gastric cancer and precancerous lesions(P<0.05).The area under the curve(AUC)of ME-NBI for the diagnosis of early gastric cancer and precancerous lesions was 0.853,the accuracy was 85.64%,the sensitivity was 88.37%,and the specificity was 83.62%.The AUC of acetate-indigo rouge staining for the diagnosis of early gastric cancer and precancerous lesions was 0.814,the accuracy was 81.68%,the sensitivity was 83.72%,and the specificity was 80.17%.The AUC of multi-slice spiral CT for the diagnosis of early gastric cancer and precancerous lesions was 0.804,with an accuracy of 80.69%,a sensitivity of 82.56%,and a specificity of 79.31%.And the AUC of the three methods combined to diagnose early gastric cancer and precancerous lesions was 0.893,with an accuracy of 89.60%,a sensitivity of 93.02%,and a specificity of 87.07%.Conclusion ME-NBI,acetate-indigo rouge staining combined with multi-slice spiral CT has high diagnostic efficacy in early gastric cancer and precancerous lesions,and can be used in clinical practice.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Objective:To improve the prognosis stratification, especially early mortality(EM), of elderly patients with newly diagnosed multiple myeloma(NDMM).Methods:In this retrospective study, univariate and multivariate Cox regression analysis were conducted to identify the independent prognostic factors associated with overall survival(OS)and the chi-square test and multivariate Logistic analysis were used to identify the prognostic factors associated with EM in 223 elderly patients(age≥65 years)with NDMM from three centers in the country.Results:Increased NT-pro-BNP(≥300 pg/ml), ECOG-PS≥2 and stage Ⅲ R-ISS were identified as three independent adverse prognostic factors of OS.The rates of EM3, EM6, EM12 and EM24 were 12.1%, 20.1%, 32.2% and 60%, respectively.The most common cause for EM6(particularly EM3)was disease-related complications resulting from ineligibility for treatment due to poor physical performance, severe organ dysfunction or treatment discontinuation due to treatment intolerance, while the most common cause for EM12(particularly EM24)was disease progression or relapse mainly as a result of inadequate treatment.R-ISS staging failed to predict EM, while decreased eGFR, ECOG-PS≥2, and increased NT-pro-BNP were able to estimate the risk of EM, with increased NT-pro-BNP as a common independent factor for EM12( P=0.03)and EM24( P=0.015). Conclusions:R-ISS staging, which primarily reflects MM biology, cannot predict EM.However, factors such as NT-pro-BNP, eGFR and ECOG-PS associated with frailty and impairment of organ functions can be used to estimate the risk of EM, among which NT-pro-BNP may be the most important independent factor for EM.Therefore, incorporation of these frailty-related biomarkers into R-ISS staging may be able to more precisely estimate the prognosis and particularly early death of elderly patients with NDMM.

Objective:To investigate the efficacy and safety of geritinib in the treatment of acute myeloid leukemia (AML) with FLT3 mutation.Methods:The clinical data of 5 AML patients with FLT3 mutation who were diagnosed in the University of Hong Kong-Shenzhen Hospital, Shenzhen People's Hospital, Shenzhen Second People's Hospital, Shenzhen University General Hospital from March 2020 to April 2021 were retrospectively analyzed. Relapsed patients concurrently received two- or three-drug chemotherapy combined with geritinib. Blood routine was checked once a week; liver function and renal function were checked once every 2 weeks during treatment. Bone marrow puncture was performed once every 1 to 3 months to monitor the bone marrow morphology, minimal residual disease (MRD) and FLT3 mutation expression levels. The efficacy, side effects, overall survival of these patients were analyzed after treatment with geritinib.Results:The white blood cell was increased in all the 5 patients at the initial diagnosis. FLT3 mutations analysis showed FLT3-internal tandem duplication (ITD) (3 cases) and FLT-3 tyrosine-kinase domain (TKD) (2 cases). Among 5 patients, 1 patient was relapse-free with maintenance therapy of oral geritinib after hematological stem cell transplantation (HSCT) for 60 days; among other 4 relapsed and refractory patients, 1 female patient after pregnancy relapsed after transplantation and then achieved complete remission followed by the maintenance therapy with geritinib after oral geritinib, 1 16-year-old patient achieved treatment outcome close to the complete remission after treatment with geritinib, 1 patient achieved complete remission after treatment with geritinib, and then underwent haplo-HSCT followed by the maintenance therapy with geritinib and the other 1 relapsed patient achieved complete remission after treatment with geritinib. After transplantation, 3 patients receiving maintenance treatment of geritinib did not relapse. The main side effects included anemia, decreased neutrophil count, rash, and increased aminotransferase. The median follow-up time of 5 patients was 15 months (6-20 months). All 5 cases survived until the last follow-up in November 2021 and 4 patients were disease-free.Conclusions:Relapsed and refractory AML patients with FLT3 mutation can achieve complete remission after treatment with geritinib and get a chance for transplantation. Geritinib may reduce the risk of recurrence after transplantation and improve survival rate. No serious side effects occur in geritinib treatment.

OBJECTIVES: We performed an updated meta-analysis to clarify the relationship between the CEBPE rs2239633 polymorphism and the childhood acute lymphoblastic leukemia (CALL) susceptibility. METHODS: All the case-control studies were updated on October 5, 2020, through Web of Science, PubMed, Cochrane Library, Embase, and China National Knowledge Infrastructure (CNKI) electronic database. The heterogeneity in the study was tested by the Q test and I RESULTS: A total of 20 case-control studies were selected, including 7014 patients and 16,428 controls. There was no association of CEBPE rs2239633 polymorphism with CALL (CC vs CT + TT: OR = 1.08, 95% CI = 0.94-1.26; CC + CT vs TT: OR = 1.10, 95% CI = 0.94-1.30; C vs T: OR = 1.02, 95% CI = 0.92-1.13). In the subgroup analysis by ethnicity, there is no significant association of this polymorphism and CALL risks among Asian and Caucasian populations in the three genetic models (CC vs CT + TT, CC + CT vs TT, and C vs T). CONCLUSION This meta-analysis found no significant association between the CEBPE rs2239633 polymorphism and susceptibility to CALL.

Objective:To summarize the clinical characteristics, common images, pathogens, and gene mutation types of chronic granulomatosis disease (CGD) in 19 children.Methods:The clinical manifestations, laboratory findings, treatment, and prognosis of 19 patients diagnosed with CGD in Hong Kong University-Shenzhen Hospital from December 2012 to December 2018 were analyzed.Results:The 19 patients were all males and confirmed as CGD by the dihydrorhodamine test and gene sequencing.The age of the first infection was mostly 1 month after birth(13 cases), and the age of clinical diagnosis ranged from 2 months to 10 years.Sixteen mothers were carriers.The patients presented with pulmonary fungal infection (19/19 cases), Bacillus Calmette Guerin (BCG)-osis (14/19 cases), lymphadenitis (14/19 cases), perianal abscess (9/19 cases), skin abscess (5/19 cases) and ulcerative colitis (2/19 cases). There were 59 positive cultures.Pathogens included fungi (9 cases), Klebsiella pneumonia (8 cases), mycobacteria (7 cases), Streptococcus Viridans (5 cases), Escherichia coli (3 cases), gram-positive bacteria (3 cases), Staphylococcus aureus (3 cases), and Burkholderia cenocepacia (2 cases). Gene mutations were found in all 19 patients, including 17 cases of CYBB, 1 case of CYBA and 1 case of NCF2.The type of mutations included nonsense mutations (6 cases), deletion mutations (5 cases, including 2 large fragment deletions), splice mutations (3 cases) and missense mutations (5 cases). Five mutations were novel.Splice mutations in 3 cases often led to skin abscess, perianal abscess and lymphadenitis.Two patients with large deletion mutations had more serious infection than other patients. Conclusions:In China, CGD is characterized with pulmonary infection and disseminated BCG-osis.Mycobacteria are common pathogens of CGD, and fungi are dominant pathogens of CGD.The most common infection is respiratory infection. Klebsiella pneumonia and Escherichia coli often lead to perianal abscess.The relationship between gene mutation types and clinical phenotypes requires further verification by big data.

Objective:To analyze the clinical course and targeted therapy of pyogenic sterile arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome.Methods:The clinical history of a 6-year-old boy with PAPA syndrome, who was admitted to Hong Kong University Shenzhen Hospital in September 2017, was reviewed. His genetic diagnosis was confirmed by whole exome sequencing. The response to targeted therapy was evaluated by comparing the inflammatory markers (erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) and serum cytokines (interleukin (IL)-1, IL-6 and tumor necrosis factor-α (TNF-α)) before and after biological agents treatment. For literature review, "PAPA syndrome" and"PSTPIP1 gene"were used as keywords to retrieve papers published from January 1997 to December 2019 from Pubmed, Wanfang and CNKI database.Results:The patient was a 6-year-old boy, admitted to the hospital due to recurrent joint swelling and pain for more than 4 years. Before treatment, the CRP (256 mg/L), ESR (105 mm/1 h) and cytokines including serum TNF-α (7.43 ng/L), IL-1 (<5 ng/L), IL-6 (301 ng/L) were significantly elevated. Culture of the joint effusion was negative, but the IL-6 level was above 1 000 ng/L. MRI showed osteomyelitis at the lower end of the right femur. Gene detection found a heterozygous variation of PSTPIP1 gene (c.748G>A, p.E250K). Arthralgia once alleviated after the initiation of tocilizumab and infliximab, but recurred after 1 year of treatment. Thereafter, the anti-IL-1 receptor antagonist (Anakinra) was commenced, followed by a significant improvement of the arthralgia, and a complete remission during the follow-up. Besides, the level of CRP, ESR, serum TNF-α, IL-1 and IL-6 were all decreased to normal on the last followed up in December 2019. Literature review found 29 articles and 87 patients in total. The initial symptoms included those of arthritis ( n=58), pyoderma gangrenosum ( n=33), and acne ( n=24). Among all the cases, 13 genotypes were confirmed, and 47 variations involved amino acid p.E250. Steroid and/or biological agents were used in most patients. Conclusions:PAPA syndrome should be suspected in children with recurrent pyogenic sterile arthritis, and an early diagnosis could be achieved by genetic test. Targeted treatment with biological agent may control the symptoms effectively. Biological agents can control symptoms of this disorder effectively.
