Objective To discuss the factors influencing the occurrence of frailty in patients with acute myocardial infarction(AMI)after receiving interventional treatment,and to construct a prediction model,to draw a nomogram,and to make the validation of the model.Methods Using convenient sampling method,a total of 462 patients with AMI,who were admitted to the Department of Cardiovascular Medicine of three Grade Ⅲ-A hospitals in Shandong Province of China from July 2023 to January 2024,were selected as the study subjects.Among them,324 AMI patients encountered from July 2023 to November 2023 were selected as modeling group,and logistic regression was used to construct a risk prediction model and draw a nomogram to visualize the model.The remaining 138 AMI patients encountered from December 2023 to January 2024 were used as the validation group.The receiver operating characteristic(ROC)curve and Hosmer-Lemeshow testing were adopted to verify the predictive effect of the model.Results Of 324 patients in the modeling group,170(52.47％)developed frailty.Univariate analysis showed that significant differences in age,education level,body mass index(BMI),Charlson comorbidity index,grip strength,walking speed,brain natriuretic peptide precursor level,physical exercise,multiple medication,and kinesophobia existed between the two groups(all P＜0.05).Multivariate logistic regression analysis revealed that age,BMI,Charlson comorbidity index,grip strength,walking speed,NT-ProBNP precursor level,physical exercise,multiple medication,and kinesophobia were the influencing factors of frailty in patients with AMI after receiving interventional treatment,with an OR value of 1.061,0.630,1.529,0.931,0.005,0.358,1.783,2.929,and 0.497 respectively.The above nine factors were used as independent variables to draw the nomogram,the area under ROC curve of the model was 0.851(95％CI:0.809-0.892),the optimal critical value was 0.562,the sensitivity was 84.1％,and the specificity was 72.1％.Hosmer-Lemeshow goodness of fit testing showed that the model had anx2=12.957 and P=0.113.Conclusion The frailty condition of AMI patients after receiving interventional treatment is at a low to medium levels.The frailty risk prediction model constructed in this study has good prediction effect,which can provide guidance for clinical nurses to timely identify high-risk patients and to promptly adopt interventional measures.

Objective:To explore the clinical efficacy and safety of a multimodal treatment regimen integrating radiotherapy, chemotherapy, and immunotherapy in patients with human epidermal growth factor receptor 2 (HER2) -negative locally advanced or advanced gastric cancer.Methods:A total of 34 patients with unresectable, HER2-negative, locally advanced or metastatic gastric/gastroesophageal junction (G/GEJ) adenocarcinoma admitted to the Affiliated Cancer Hospital of Guizhou Medical University from September 2021 to March 2024 were selected as study objects. Participants received one cycle of either XELOX regimen (capecitabine + oxaliplatin) or SOX regimen (S-1 + oxaliplatin) with immunotherapy (sintilimab or nivolumab) . The process was succeeded by radiotherapy targeted at the primary G/GEJ tumor and regional lymph nodes. In selected cases, sequential radiotherapy was also administered for distant metastases. The primary endpoint was objective response rate (ORR) , and secondary endpoints were disease control rate (DCR) , clinical symptom response, changes in Karnofsky performance status (KPS) score, progression-free survival (PFS) , and adverse reactions. Clinical efficacy was assessed in accordance with Response Evaluation Criteria in Solid Tumors version 1.1. Adverse reactions were assessed and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 and the Chinese Society of Clinical Oncology guidelines for management of immune checkpoint inhibitor-related toxicity. With a median follow-up of 7 months (range: 2.3 to 30 months) , the final evaluation considered the best response documented throughout follow-up. Survival curves were constructed utilizing Kaplan-Meier analysis.Results:By the end of follow-up, an overall ORR of 58.8% (20/34) and DCR of 70.6% (24/34) were observed. The ORR of lesions by radiotherapy reached 73.8% (48/65) and the DCR reached 92.3% (60/65) . Univariate analysis showed that the ORR of female patients (84.6%, 11/13) was higher than that of male patients (42.9%, 9/21) , and the ORR of patients with distant lymph node metastasis alone (83.3%, 15/18) was higher than that of patients with distant lymph node metastasis combined with organ metastasis or organ metastasis alone (18.2%, 2/11) , with statistically significant differences ( P=0.030; P=0.010) . There were no statistically significant differences in ORR among patients with different age ( P=0.487) , KPS score ( P=0.198) , primary tumor location ( P=0.280) , histological differentiation ( P=0.668) , chemotherapy regimen ( P=0.728) , or immunotherapy regimen ( P>0.999) . Twenty-two of 23 (95.7%) patients with upper abdominal pain were relieved, 10 of 21 (47.6%) patients with appetite loss were relieved, 15 of 17 patients with upper abdominal distension were relieved, 13 of 14 patients with melena were relieved, 6 of 7 patients with eating obstruction were relieved, 3 of 4 patients with metastatic site pain were relieved, and 2 patients with hematemesis were relieved. KPS score enhanced in 82.4% (28/34) of patients, remained stable in 11.8% (4/34) , and declined in 5.8% (2/34) . The median PFS of the 34 patients was 7.9 months. The most common adverse reactions during radiotherapy combined with chemotherapy and immunotherapy were hematological adverse reactions, in which neutropenia accounted for the highest proportion (91.2%, 31/34) , followed by anemia (50.0%, 17/34) . Fatigue was the most common non-hematological adverse reaction (50.0%, 17/34) , followed by nausea and vomiting (26.5%, 9/34) . The adverse reactions of 6 patients receiving immune monotherapy maintenance were anemia, hypothyroidism, transaminase elevation, proteinuria, fatigue, and rash, all of which were grade 1-2. Conclusions:Radiotherapy combined with chemotherapy and immunotherapy shows good short-term clinical efficacy in patients with HER2-negative locally advanced or advanced gastric cancer, and the overall adverse reactions are tolerable. Female or patients with distant lymph node metastasis alone may be the preferred population for this study protocol.

Objective To observe the clinical efficacy of Huangqi Danggui Compound Decoction(mainly composed of Astragali Radix,Angelicae Sinensis Radix,etc.)combined with Shi's Acupuncture Therapy in the treatment of postpartum low back pain due of qi and blood depletion type.Methods A total of 138 patients diagnosed with postpartum low back pain from March 2021 to February 2024 in the outpatient and inpatient departments of the Second Affiliated Hospital of Hebei University of Chinese Medicine were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 69 cases in each group.The control group was treated with Ibuprofen Sustained-Release Capsules combined with Shi's Acupuncture Therapy,while the observation group was additionally treated with Astragalus and Angelica Compound Decoction on the basis of the control group's treatment.Both groups were treated for 4 weeks.After treatment,the clinical efficacy of the two groups was evaluated.The changes in Oswestry Disability Index(ODI)and Visual Analogue Scale(VAS)scores before and after treatment,as well as the SF-36 Quality of Life Scale scores,were observed.The changes in follicle-stimulating hormone(FSH),luteinizing hormone(LH),and estradiol(E2)levels were compared before and after treatment,and the safety and incidence of adverse reactions in the two groups were evaluated.Results(1)The total effective rate in the observation group was 92.75%(64/69),while it was 79.71%(55/69)in the control group.The efficacy of the observation group was superior to that of the control group,with a statistically significant difference(P＜0.05).(2)After treatment,the ODI and VAS scores of both groups were significantly improved(P＜0.05),and the observation group showed significantly better improvement in ODI and VAS scores compared to the control group,with a statistically significant difference(P＜0.05).(3)After treatment,the SF-36 Quality of Life Scale scores of both groups improved significantly(P＜0.05),and the observation group showed significantly better improvement in SF-36 scores compared to the control group,with a statistically significant difference(P＜0.05).(4)After treatment,the FSH,LH,and E2 levels in the observation group were significantly improved(P＜0.05),and the observation group showed significantly better improvement in FSH,LH,and E2 levels compared to the control group,with a statistically significant difference(P＜0.05).In the control group,the FSH,LH,and E2 levels improved slightly,but there was no statistically significant difference compared to before treatment(P＞0.05).(5)There was no statistically significant difference in the incidence of adverse reactions between the observation group and the control group(P＞0.05).Conclusion Huangqi Danggui Compound Decoction combined with Shi's Acupuncture Therapy in the treatment of postpartum low back pain due to qi and blood depletion can significantly alleviate pain symptoms,improve lumbar function,regulate sex hormone levels,and enhance the quality of life of patients,with significant efficacy and good safety.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China.

Objective:To explore the pattern of lymph node metastasis and prognosis in locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy (NICT).Methods:This retrospective study included pathologically confirmed gastric adenocarcinoma (cT3-4aN+) patients who underwent radical resection after ≥2 cycles of PD-1 inhibitor-based chemotherapy with complete postoperative pathology. Exclusions: distant/other metastases, non-R0 resection, Her-2+ with targeted therapy, microsatellite instability, or esophagogastric junction cancer invading >1 cm into lower esophagus. From January 2020 to December 2024, a total of 343 consecutive gastric cancer patients who received NICT treatment were admitted to Tianjin Medical University Cancer Institute and Hospital. According to the above criteria, 324 cases were included in the lymph node metastasis analysis, and 302 cases were included in the survival analysis. The median age of all patients was 58 years, with 245 males (75.6%) and a median body mass index (BMI) of 22.9 kg/m2. There were 170 cases (52.5%) at T3 stage and 154 cases (47.5%) at T4a stage; the median number of cycles of neoadjuvant immunotherapy combined with chemotherapy was 3 cycles. The primary outcome measure was the positive lymph node metastasis rate (number of metastatic cases in the group / total number of dissected cases in the group×100%). A positive lymph node metastasis rate >10% was defined as high metastasis, and <5% as low metastasis. The secondary outcome measures were high-risk factors for lymph node metastasis and influencing factors related to patient prognosis. Lymph node grouping was performed according to the 8th edition of the American Joint Committee on Cancer (AJCC) guidelines. The positive lymph node metastasis rate was statistically analyzed by stratification based on surgical methods (total gastrectomy, proximal gastrectomy, distal gastrectomy). Multivariate analysis of risk factors for lymph node metastasis were performed with logistic regression analysis, and survival analysis were performed with the Kaplan-Meier method and Cox regression model.Results:The postoperative pathological complete response rate (pCR) of all patients was 21.0% (68/324), and the overall positive lymph node metastasis rate was 48.8% (158/324). A total of 150 patients underwent total gastrectomy, 42 underwent proximal gastrectomy, and 132 underwent distal gastrectomy.In the total gastrectomy group: the high metastasis subgroups were No.1 (19.3%, 29 cases), No.2 (14.7%, 22 cases), No.3 (28.0%, 42 cases), No.7 (12.7%, 19 cases), No.8a (16.0%, 24 cases), and No.9 (17.3%, 26 cases); the low metastasis subgroups were No.5 (4.7%, 7 cases), No.10 (3.3%, 5 cases), No.11d (1.3%, 2 cases), and No.12a (4.0%, 6 cases).In the proximal gastrectomy group: the high metastasis subgroups were No.3 (14.3%, 6 cases), No.7 (23.8%, 10 cases), and No.11p (11.9%, 5 cases); the low metastasis subgroups were No.4d (2.4%, 1 case) and No.10 (2.4%, 1 case).In the distal gastrectomy group: the high metastasis subgroups were No.3 (25.8%, 34 cases), No.6 (26.5%, 35 cases), No.7 (11.4%, 15 cases), and No.11p (11.4%, 15 cases); the low metastasis subgroups were No.4sb (3.8%, 5 cases) and No.12a (4.5%, 6 cases).Results of multivariate analysis showed that TRG grade (HR: 5.938, 95%CI: 3.028-11.646, P<0.001) was an independent factor affecting lymph node metastasis in patients with locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy. The median follow-up time was 26.0 (6.0-54.3) months, and the 3-year overall survival (OS) of all patients was 78.1%. Results of multivariate Cox analysis showed that ypT (HR=1.744, 95%CI: 1.300-2.338, P<0.001), ypN (HR=1.998, 95%CI: 1.503-2.655, P<0.001), and postoperative complications (HR=1.913, 95%CI: 1.111-3.294, P=0.019) were independent factors affecting the overall survival of patients with locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy. Conclusion:NICT significantly changes the pattern of lymph node metastasis in LAGC. ypT and ypN stages are core indicators for survival prognosis. The necessity of dissection for lymph node groups with a metastasis rate <5% needs to be carefully evaluated.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective To explore the effects of hot compress by aconite tincture combined with medium-frequency electrotherapy on lumbar spine function, lumbar muscle endurance, and inflammatory factors in patients with chronic non-specific low back pain. Methods A total of 120 patients with chronic non-specific low back pain were randomly divided into two groups, with 60 patients in each group. The control group was treated with medium-frequency electrotherapy, while the research group was treated with aconite tincture hot compress based on the treatment of the control group. The symptom improvement, lumbar spine function, lumbar muscle endurance, and serum inflammatory factor levels after treatment were compared between the two groups. Results The total effective rate of the research group was 96.67%, which was higher than 83.33% of the control group (P < 0.05). After treatment, the Visual Analogue Scale (VAS) score of the research group was lower than that of the control group, and the Japanese Orthopaedic Association (JOA) score was higher than that of the control group (P < 0.05). The lumbar muscle endurance test time was prolonged in both groups after treatment, and was longer in the research group than that of the control group (P < 0.05). After treatment, the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) in the research group were lower than those in the control group(P < 0.05). The total incidence of adverse reactions in the control group was 30.00% (18/60), and 23.33% (14/60) in the research group, but no statistically significant difference was found (χ²=0.682, P=0.409). Conclusion The combination of hot compress by aconite tincture and medium-frequency electrotherapy has significant therapeutic effects in patients with chronic non-specific low back pain, which can significantly reduce the pain symptoms ofthe lumbar spine, improve lumbar spine function, and reduce the level of inflammatory factors.

Objective To analyze the correlation between serum miR-939 and miR-15b expression and mi-crovascular injury in patients with diabetic retinopathy(DR).Methods A total of 176 patients with type 2 di-abetes diagnosed and treated in the Baoding Second Hospital from January 2021 to October 2022 were selected as the study objects.The subjects were divided into 74 patients without DR(NDR group),62 patients with non-proliferative DR(NPDR group)and 40 patients with proliferative DR(PDR group)according to whether or not DR occurred and the degree of lesions.Real-time fluorescent quantitative PCR was used to detect the relative expression levels of miR-939 and miR-15b in serum of all groups,the level of vascular endothelial growth factor(VEGF)was detected by enzyme-linked immunosorbent assay,and the count percentage of en-dothelial cells(ECs),endothelial progenitor cells(EPCs)and circulating progenitor cells(CPCs)was detected by flow cytometry.Serum levels of miR-939,miR-15b,VEGF and ECs,EPCs and CPCs were compared in 3 groups.Pearson correlation was used to analyze the correlation between serum miR-939 and miR-15b and VEGF,ECs,EPCs and CPCs.Multivariate Logistic regression was used to analyze the factors affecting the oc-currence of DR in patients with type 2 diabetes.Results The relative expression levels of miR-939 and miR-15b in PDR group and NPDR group were lower than those in NDR group,while the serum VEGF levels were higher than those in NDR group,with statistical significance(P＜0.05).ECs in PDR group and NPDR group were higher than those in NDR group,while EPCs and CPCs were lower than those in NDR group,the differ-ence was statistically significant(P＜0.05).Serum miR-939 was negatively correlated with VEGF and ECs(r=-0.407,-0.613,P＜0.05),and positively correlated with EPCs and CPCs(r=0.481,0.486,P＜0.05).Serum miR-15b was negatively correlated with VEGF and ECs(r=-0.539,-0.625,P＜0.05),and positively correlated with EPCs and CPCs(r=0.451,0.483,P＜0.05).Multivariate Logistic regression anal-ysis showed that the duration of type 2 diabetes,hemoglobin A1c,2-hour postprandial blood glucose,VEGF,miR-939 and miR-15b were the influencing factors for the occurrence of DR in type 2 diabetes patients(P＜0.05).Conclusion The expression of miR-939 and miR-15b in serum of DR patients is closely related to VEGF,ECs,EPCs and CPCs,and the expression of miR-939 and miR-15b in serum of DR patients can provide a certain reference for early judgment and evaluation of the degree of microvascular injury.
