Objective To investigate the effects of dapagliflozin on inflammatory factors and prognosis in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI). Methods In a randomized, double-blind trial, 146 patients with T2DM and AMI (within 7 days of onset) were divided into dapagliflozin (dapagliflozin 10 mg/d combining AMI standard therapy) and control (AMI standard therapy) groups, and were followed up for 12 months. Serum levels of interleukin-1β (IL-1β), IL-6, high-sensitivity C reactive protein (hs-CRP) at baseline, 1, 3, 6, and 12 months, and left ventricular ejection fraction (LVEF), brain natriuretic peptide (BNP), and major adverse cardiovascular events (MACE) rate at 12 months were compared between the two groups. Kaplan-Meier curves were used to analyze the cumulative incidences of MACE in the two groups. Results Three patients were withdrawn or dropped out. At 12 months, IL-1β, IL-6, and hs-CRP levels were significantly lower in dapagliflozin group (n＝71) than those in control group (n＝72, P＜0.01), approaching normal levels. Compared with the control group, LVEF was higher (P＜0.01), BNP was lower (P＜0.01), MACE incidence was lower (P＝0.047) in dapagliflozin group at 12 months. Generalized linear mixed models showed significant group-time interactions in IL-1β, IL-6, and hs-CRP (P＜0.001), and these factors declined faster in the dapagliflozin group. Kaplan-Meier curve showed the cumulative incidences of MACE and heart failure were lower in dapagliflozin group than those in non-dapagliflozin group (P＜0.05). Conclusions For patients with T2DM patients and AMI, dapagliflozin has good anti-inflammatory and cardioprotective effects.

Addressing the current clinical problems of conventional antidepressants， such as delayed onset of action and prominent adverse reactions， this paper explores the theoretical basis， mechanism of action， and application prospects of nasal administration as a novel rapid antidepressant strategy. By clarifying the conceptual connotation of rapid antidepressants， elucidating their clinical demands and application advantages， and explaining the physiological basis of nasal-to-brain delivery， it is proposed that the olfactory and trigeminal nerve pathways can bypass the blood-brain barrier to achieve rapid targeted delivery of drugs to brain tissue. On this basis， combined with the theory of opening orifices with aromatic medicinals in traditional Chinese medicine （TCM） as well as related research in modern aromatherapy， the ancient and modern clinical evidence of nasal administration in regulating emotions was systematically reviewed. Furthermore， this article discusses the application advantages of nasal administration in special populations such as the elderly， children， and pregnant women， and analyzes the practical bottlenecks such as mucosal clearance， limited formulation volume， and safety evaluation. Nasal administration is expected to become an important supplementary means for rapid antidepressants， and the integrated model of "TCM aromatic medicinals plus nanopreparations plus nasal administration" can provide new ideas for research on the integration of TCM and western medicine in treating depression.

BACKGROUND:Acupoint embedding and floating needle therapy are two methods for the treatment of knee osteoarthritis,but there are few reports on the combined treatment of the two methods. OBJECTIVE:To investigate the therapeutic effect of acupoint embedding combined with floating needle therapy on different stages of knee osteoarthritis using generalized estimating equations. METHODS:A total of 436 patients with knee osteoarthritis admitted to Dongguan Hospital of Traditional Chinese Medicine from February 2019 to February 2023 were selected as the research subjects.All patients were randomly divided into a control group with floating needle therapy(n=218)and an observation group with acupoint embedding method combined with floating needle therapy(n=218).Staging was performed according to the K-L staging method.In the control group,there were 57 cases in stage Ⅰ,62 in stage Ⅱ,49 in phase Ⅲ,and 50 in stage Ⅳ,while in the observation group,there were 48 cases in stage Ⅰ,66 in stage Ⅱ,63 in phase Ⅲ,and 41 in stage Ⅳ.The levels of indexes and clinical efficacy were compared between groups before and after treatment.Generalized estimating equation model was used to analyze the influencing factors of clinical efficacy and the interaction effect of different time points,different methods and different stages on therapeutic efficacy. RESULTS AND CONCLUSION:There was no significant difference in baseline data between the observation group and the control group,as well as between the patients of different stages(P>0.05).After treatment,the cure rate of stage Ⅰ patients was the highest after treatment,and the total improvement rate in the observation group was significantly higher than that in the control group.There were significant differences in the cure rate among different stages in each group(P<0.05).After treatment,all indicators in the two groups were significantly decreased.In the control group,there were significant differences in various indicators of patients at different stages after 4 weeks of treatment(P<0.05).In the observation group,after 2 weeks of treatment,there were significant differences in various indicators of patients at different stages(P<0.05),and all the indexes in the observation were lower than those in the control group after 4 weeks of treatment(P<0.05)and the therapeutic effect in the observation group was better than that in the control group.Generalized estimating equation model analysis showed that trauma history,interleukin-6 level,treatment method,treatment time and K-L stage all significantly affected the clinical efficacy in patients.In the interaction effect analysis,after 2 weeks of treatment,there was a significant difference in the visual analogue scale score between the two groups in stages Ⅲ and Ⅳ(P<0.05).After 4 weeks of treatment,there was a significant difference in the visual analogue scale score between the two groups in stages Ⅱ,Ⅲ,and Ⅳ(P<0.05).To conclude,acupoint embedding combined with floating needle therapy is superior to floating needle therapy alone in the treatment of different stages of knee osteoarthritis.Trauma history,interleukin-6 level,treatment method,treatment time and K-L stage significantly influence the therapeutic effect.

Objective To investigate the relationship between primary pulmonary mucinous adenocarcinoma (PPMA) mass type and pneumonia type and their difference in malignant degree, and to analyze the role of clinical manifestations and CT features in the diagnosis of this disease. Methods The clinical data of PPMA patients admitted in the First Affiliated Hospital of Xiamen University from May 2011 to March 2022 were retrospectively analyzed. According to CT features, they were divided into a mass type group and a pneumonia type group. The clinical manifestations, CT features and the degree of malignancy between the two groups were analyzed and compared. Results A total of 57 PPMA patients were enrolled. There were 17 males and 40 females, with an average age of (53.82±10.65) years, and 28 (49%) patients had reversed hato-like sign. There were 42 patients in the mass type group and 15 patients in the pneumonia type group. PPMA often occurs in both lower lungs, with clinical manifestations mainly of coughing and expectorating white mucoid sputum. There were statistical differences between the two groups in the maximum diameter of tumor (P<0.001), boundary condition (P<0.001) and pleural indentation sign (P=0.019). There was no statistical difference between the two groups in Ki-67 index (P>0.05). Conclusion There is no statistical difference in the degree of malignancy between the two types of PPMA. Considering their clinical manifestations and differences in imaging features, it is supported that the pneumonia type is just a progression of the mass type. CT can present various manifestations, among which the reversed hato-like sign is expected to become an important imaging feature. Combined with a high proportion of solid components, pleural indentation sign, and vacuole sign, reversed hato-like sign can play a significant role in the diagnosis of PPMA.

Objective To explore the impact of early discharge guidance,based on an intelligent education system,on postoperative pain management,functional recovery,and discharge readiness in lung cancer patients.Methods A total of 170 lung cancer patients were selected from Jinhua Municipal Central Hospital from July 2022 to June 2023.According to the time of admission,patients admitted between July to November 2022 were assigned to control group(n=82),while patients admitted between December 2022 to June 2023 were assigned to observation group(n=88).Control group received routine perioperative health education,while observation group received additional intelligent education system.Following outcomes were compared between two groups:Time to first ambulation after surgery,pain numeric rating scale(NRS)scores on postoperative 1 to 3 days and on day of discharge,performance on 2-minute step test on day of discharge,and readiness for hospital discharge scale(RHDS).Results Time to first ambulation post operative in observation group was shorter than that in control group.NRS scores at 72 hours post operative and on day of discharge were lower in observation group compared to control group.Number of steps completed in 2-minute step test in observation group was higher than that in control group.Additionally,RHDS scores in observation group was higher than that in control group,and all differences were statistically significant(P＜0.05).Conclusion The discharge planning advancement driven by the intelligent education system significantly improved early postoperative ambulation,reduced postoperative pain,enhanced physical function,and increased discharge readiness in lung cancer patients,thereby effectively promoting postoperative recovery.

Objective:To evaluate the impact of donor characteristics on the prognosis of myelodysplastic syndrome (MDS) patients undergoing haplo-identical transplantation (HIDT) .Methods:A retrospective analysis of 203 MDS patients who received HIDT was conducted to evaluate how donor factors influenced transplant outcomes.Results:In MDS patients undergoing haploidentical transplantation, donors over 50 years were associated with higher EBV reactivation (2-year cumulative incidence 42.9% vs 22.0% for <50 years old; P=0.010). Female donors were linked to increased severe chronic GVHD compared with male donors (2-year incidence 11.9% vs 4.0% ; P=0.017). Additionally, 2-year overall survival (OS) was slightly lower with female donors than male donors (56.6% vs 69.7% ), but the difference was not statistically significant ( P=0.073). Donor-recipient blood type did not affect post-transplant OS or cumulative relapse rates. Donor-recipient kinship analysis revealed that child donors, compared to haploidentical sibling or parent donors, had lower rates of grade Ⅱ–Ⅳ acute GVHD (27.2% vs 45.7% vs 53.5%, P=0.007) and 2-year EBV reactivation (13.9% vs 29.3% vs 38.9%, P=0.001). For donors under 20 years, donor gender did not significantly affect 2-year OS ( P=0.913), relapse-free survival ( P=0.716), or 100-day incidence of grade Ⅱ–Ⅳ acute GVHD ( P=0.359) . Conclusion:For MDS patients undergoing HIDT, donors over 50 should be avoided. Male and child donors are preferred, while donor gender does not significantly affect outcomes if the donor is under 20 years old.

Objective:To investigate the relationship between susceptibility to hearing loss in noise-exposed Han Chinese male homo sapiens and glutathione S-transferase (GST) gene polymorphisms, providing a scientific basis for further understanding the pathogenic mechanisms of noise-induced hearing loss (NIHL) and screening for genetic susceptibility biomarkers.Methods:In May 2024, a cross-sectional survey was conducted to recruit 332 male Han workers exposed to noise from a prominent mechanical maintenance enterprise. Workers were classified into the hearing loss group if they exhibited a binaural high-frequency average hearing threshold exceeding 25 dB and a binaural speech frequency average hearing threshold loss that was less than the binaural high-frequency average hearing threshold loss, resulting in a total of 332 individuals in this group. Furthermore, a matched group of 332 hearing-normal workers was established on a 1∶1 basis for each hearing-impaired worker, using criteria such as the same job type, age, and a noise exposure duration of ≤4 years. Basic data of worker was collected through a questionnaire survey, and individual noise exposure levels were assessed using cumulative noise exposure (CNE). Various PCR and high-throughput sequencing techniques were employed to identify polymorphisms in the GSTT1, GSTM1, and GSTP1rs1695 genes. The basic information and genotypes of the two groups were compared using paired t-tests and paired chi-square tests. A Cox regression model was utilized to establish a 1∶1 paired logistic regression model to examine the correlation between GST gene polymorphisms and susceptibility to NIHL. Results:Individuals with GSTM1 and GSTT1 gene deletion are more susceptible to NIHL compared to those with existing genes, even after adjusting for other factors ( OR=1.464, 95% CI: 1.02-2.09; OR=0.68, 95% CI: 1.06-2.02). Wearing protective equipment occasionally, rather than consistently, significantly increases the risk of NIHL ( OR=1.38, 95% CI: 1.01-1.88). There was no link between GSTP1rs1695 polymorphism and NIHL risk ( P>0.05) . Conclusion:The deletion of GSTM1 and GSTT1 genes is an independent influencing factor that increases the risk of NIHL, and can be considered as a genetic susceptibility biomarker for the NIHL population. Strengthening personal hearing protection is an effective measure to reduce the risk of NIHL.

Objective:To retrospectively analyze the pathogenic factors of retrograde peri-implantitis (RPI) and assess the effectiveness of treatment, and to provide clinicians evidence for the prevention and treatment of RPI.Methods:A total of 2 731 patients with missing teeth (4 016 implants) who underwent implant restoration in the Department of Stomatology, The First Affiliated Hospital of Wenzhou Medical University between January 2004 and December 2022 were included in the study. According to the diagnostic criteria of RPI, a total of 20 cases (23 implants) of RPI were collected, including 4 female (5 implants) and 16 male (18 implants), and the treatment medical records, intraoral photos and cone beam CT or oral panoramic radiographs records of each patient were collected. Each patient with RPI was treated accordingly and followed up regularly to evaluate its efficacy.Results:After treatment, the follow-up time for 20 patients with clinical symptoms of RPI was 13 (6, 40) months (1 month to 13 years), and the survival rate of the treated implants was 91% (21/23). There were 7 patients (8 implants) with inactive RPI, no clinical symptoms, no loosening of the implant, with normal occlusal load, and the disease was at the inactive stage and was not treated. The pulp vitality of the natural tooth adjacent to the implant was normal, and the implant could function normally. There were 13 patients (15 implants) with infected RPI, 1 patient (1 implant) had no loosening of the implant, and the periapical radiolucency of the implant disappeared after endodontic treatment of the natural tooth adjacent to the implant; 12 patients (14 implants) had clinical symptoms such as implant loosening, pus discharge, etc. Among them, 10 patients (12 implants) were successfully implanted in situ or in adjacent sites after removing the implants, and were successfully implanted after 3 to 20 months. Two patients(2 implants) were removed and no further implants were placed. Among them, 2 implants with infected RPI had cystic lesions, which was similar to natural root apex cysts.Conclusions:The etiology of RPI is related to inflammation of adjacent tooth root tips or bacterial residues from inflammatory lesions in the alveolar bone and bone augmentation. RPI can be treated by perfect root canal treatment of adjacent teeth, removal of inflammatory tissue, or simultaneous guided bone regeneration techniques.

Objective:To understand the knowledge, attitudes, and behaviors of residents in areas endemic for severe fever with thrombocytopenia syndrome (SFTS) and the factors influencing these aspects, to provide a scientific basis for the prevention and control of SFTS among residents in endemic areas.Methods:A multi-stage sampling method was used to select subjects for a questionnaire survey, and the collected data were analyzed and compared.Results:The awareness rate of SFTS-related knowledge among residents in the endemic areas of Qingdao was 14.38%, while the awareness rate of tick-related knowledge was 69.78%. The mean score for protective attitudes among residents in the endemic areas was 24.50±4.09, and the mean score for protective behaviors was 11.20±2.76. Among residents of different ages, occupations, and educational levels, comparisons of SFTS-related knowledge awareness rates ( χ2=293.553, P<0.001; χ2=495.216, P<0.001; χ2=677.272, P<0.001), tick-related knowledge awareness rates ( χ2=29.986, P<0.001; χ2=23.239, P=0.002; χ2=41.003, P<0.001), protective attitude scores ( H=52.094, P<0.001; H=33.446, P<0.001; H=81.715, P<0.001), and protective behavior scores ( H=52.344, P<0.001; H=28.465, P<0.001; H=67.061, P<0.001) showed statistically significant differences. Comparisons of these same factors among residents of different genders showed no statistically significant differences ( χ2=1.159, P=0.282; χ2=0.298, P=0.585; t=-0.808, P=0.419; t=-1.229, P=0.219). Comparisons of tick-related knowledge awareness rates among residents with different frequencies of outdoor work showed no statistically significant differences ( χ2=5.367, P=0.147); however, comparisons of SFTS-related knowledge awareness rates, protective attitude scores, and protective behavior scores among residents with different frequencies of outdoor work showed statistically significant differences ( χ2=117.010, P<0.001; F=4.127, P=0.006; H=56.280, P<0.001). Multivariate linear regression analysis revealed that older age, lower educational level, and less frequent outdoor work were associated with lower protective behavior scores ( t=-3.479, P<0.001; t=4.861, P<0.001; t=-7.753, P<0.001). Conclusions:Residents in the epidemic areas of SFTS have a low level of knowledge, attitude and practice. Factors influencing protective behaviors include age, occupation, educational level, and frequency of outdoor work. Farmers are a group that requires particular attention.
