OBJECTIVE To evaluate the safety of fondaparinux in pregnancy and provide reference for its rational clinical application. METHODS A search was conducted in databases including CNKI， Wanfang， PubMed， Embase， and Elsevier （the search time was from the construction of the database to December 17， 2024） to collect case report literature on fondaparinux use during pregnancy. Patient demographic information， fondaparinux use during pregnancy， concomitant medications， clinical manifestations， and treatment details were extracted for descriptive statistical analysis. RESULTS A total of 17 case reports regarding the use of fondaparinux during pregnancy were collected， involving 42 patients from 11 countries and 47 pregnancy records. Among these， 20 cases involved the use of fondaparinux for the prevention of pregnancy-related venous thromboembolism （VTE）， while 27 cases were fondaparinux treatment due to related conditions. A total of 29 occurrences of the patients were treated with fondaparinux due to a （family） history of VTE. Nine occurrences of complicated pregnancies were reported， and 35 patients had records of comorbidities or relevant medical histories. The adverse events that occurred during pregnancy with the use of fondaparinux include postpartum hemorrhage （7 cases） and excessive anticoagulation caused by inappropriate dosage （1 case）. Among the 7 cases of postpartum hemorrhage， 3 cases had a blood loss of no less than 1 000 mL （including 2 cases with uterine atony）， 3 cases had a drug discontinuation time of ≤12 h. CONCLUSIONS Based on the existing literature， the safety of fondaparinux during pregnancy is generally manageable， with the main adverse event being postpartum hemorrhage. The dosage， interval between discontinuation，comorbidities/medical history， and concomitant medications of fondaparinux may be the main causes of its adverse events.

This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

Objective: To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention. Methods: From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD. Conclusions The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.

Objective:To identify the relationship between the CT arterial radiomics score and the treatment response to neoadjuvant therapy for pancreatic cancer.Methods:The clinical data of 243 pancreatic cancer patients who received surgical resection after neo-adjuvant therapy in the First Affiliated Hospital of Naval Medical University from March 2017 to March 2023 were retrospectively analyzed. Based on the tumor regression grade (TRG), the patients were divided into good response group (TRG 0-1, n=30) and non-good response group (TRG 2-3, n=213). The clinical, radiological and pathological features were compared between two groups. Fully-automated segmentation tool was used for segmenting the arterial CT scan of pancreatic tumor before and after treatment. Python package was applied to extract the radiomics features of tumors after segmentation and the extracted features were reduced and chosen using the least absolute shrinkage and selection operator (Lasso) logistic regression algorithm. Lasso logistic regression formula was applied to calculate the arterial radiomics score. Univariate and multivariate logistic regression models were used to analyze the association between arterial radiomics score and treatment response to neoadjucant therapy. Receiver operating-characteristics (ROC) curve was drawn and area under curve (AUC), specificity, sensitivity and accuracy for evaluating the treatment response were calculated. The clinical usefulness of arterial radiomics score for diagnosing the response of neoadjuvant treatment for pancreatic cancer were determined by decision curve analysis (DCA) . Results:A total of 330 arterial radiomics CT features were obtained, and 9-selected arterial phase features associated with treatment response were determined after being reduced by the Lasso logistic regression algorithm. Univariate analysis showed that the arterial radiomics score, three-dimensional diameter after neoadjuvant therapy, pancreatic contour, T stage, N stage, Peri-pancreatic nerve invasion, lymph-vascular space invasion (LVSI) and invasion of duodenum were all associated with treatment response (all P value <0.05). Multivariate logistic regression analyses confirmed that arterial radiomics score was obviously associated with the neoadjuvant treatment response ( P<0.001). At the cut-off value of 1.93, AUC of the arterial radiomics score for diagnosing neoadjuvant treatment response was 0.92, and the specificity, sensitivity and accuracy was 86.7%, 84.5% and 84.8%. DCA demonstrated that when the percentage for predicting the treatment response by using the arterial radiomics score was >0.2, the patients could benefit from the application of arterial radiomics score for evaluating neoadjuvant therapy response. Conclusions:The arterial radiomics score was strongly correlated with the neoadjuvant treatment response of pancreatic cancer, and can accurately predict neoadjuant treatment efficacy.

Objective:To investigate the expression of complement C3 in serums and tissues of lung adenocarcinoma patients with brain metastases and the mechanism of complement C3 in inducing epithelial mesenchymal transition (EMT).Methods:The retrospective case-control study, cell experiments and animal experiments were conducted. The serum samples from 20 healthy examinees, 20 advanced lung adenocarcinoma patients without brain metastases and 20 advanced lung adenocarcinoma patients with brain metastases at the First People's Hospital of Yancheng from January 2021 to January 2023 were collected, and the expression of complement C3 in serum samples was detected by immunoturbidimetry. At the same time, lung tissue samples were collected from 10 lung adenocarcinoma patients without brain metastases, and lung tissue and brain tissue samples were collected from 10 lung adenocarcinoma patients with brain metastases in the First People's Hospital of Yancheng. Immunohistochemistry was used to detect the expression of complement C3, C3aR, Kruppel like factor 5 (KLF5), and N-cadherin (N-cad) in the tissue samples. Using lentivirus to construct a human lung adenocarcinoma with brain metastases cell line PC14-C3 with stable overexpression of complement C3, with cells infected with empty vector virus as the control group (PC14-Ctrl). Western blotting was used to detect the expression of complement C3, KLF5, N-cad, and E-cadherin (E-cad) in PC14-C3 and PC14-Ctrl cells, and scratch assay was used to assess cell migration ability. Using the random number table method, 12 BALB/c nude mice were evenly divided into PC14-C3 group and PC14-Ctrl group. PC14-C3 cells and PC14-Ctrl cells were subcutaneously inoculated on the ventral side, and the body mass and tumor volume of the nude mice were recorded. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of KLF5, N-cad and E-cad mRNA in various tumor cells and tumor tissues of nude mice.Results:The serum complement C3 levels in healthy individuals, lung adenocarcinoma patients without brain metastases and lung adenocarcinoma patients with brain metastases were (1.14±0.17) g/L, (1.20±0.15) g/L and (1.61±0.21) g/L, respectively. The serum complement C3 level in lung adenocarcinoma patients with brain metastases was higher than that in lung adenocarcinoma patients without brain metastases and healthy individuals, and the differences were statistically significant (both P < 0.001). The results of immunohistochemical testing showed that the proportions of positive expression areas of complement C3, C3aR, KLF5, and N-cad proteins in the lung primary lesions of lung adenocarcinoma patients with brain metastases were higher than those of patients without brain metastases, and the differences were statistically significant (all P < 0.05). The mRNA ( P < 0.05) and protein expression levels of complement C3 in PC14-C3 cells were higher than those in PC14-Ctrl cells, indicating successful transfection. The scratch assay results showed that the migration rate of PC14-Ctrl cells was (37.5±4.1)%, and the migration rate of PC14-C3 cells was (60.4±2.9)%, and the difference was statistically significant ( t = 7.86, P < 0.01). The relative expressions of EMT promoting molecules KLF5 and N-cad mRNA in PC14-C3 cells were higher than those in PC14-Ctrl cells, while the relative expression of EMT inhibiting molecule E-Cad mRNA was lower than that in PC14-Ctrl cells, and the differences were statistically significant (all P < 0.05). On the 26th day of tumor loading, the tumor volume of nude mice in PC14-C3 group was (610±10) mm 3, while that of PC14-Ctrl group was (321±30) mm 3; the body mass of nude mice in PC14-C3 group was lower than that in PC14-Ctrl group [(21.6±0.6) g vs. (23.2±0.6) g], and the differences were statistically significant (both P < 0.05). At the end of the experiment, 5 nude mice died and 1 survived in the PC14-C3 group; 1 nude mouse died and 5 survived in the PC14-Ctrl group. The relative expressions of KLF5 and N-cad mRNA in the tumor tissues of nude mice in PC14-C3 group were higher than those in PC14-Ctrl group, while the relative expression of E-Cad mRNA was lower than that in PC14-Ctrl group, and the differences were statistically significant (all P < 0.05). Conclusions:Lung adenocarcinoma patients with brain metastases have high levels of complement C3 in their serums and primary lesions. Complement C3 may induce EMT and promote the occurrence of lung adenocarcinoma brain metastases by affecting the expressions of KLF5, N-cad and E-cad.

Objective:To explore the clinical efficacy of small incision floating line drainage for the treatment of high perianal abscess.Methods:A retrospective analysis was conducted on the clinical data of 95 patients with high perianal abscess treated at the Medical Community General Hospital of Shaoxing Central Hospital from April 2019 to April 2021. Among them, 47 cases were treated with small incision floating line drainage (experimental group), and 48 cases were treated with conventional multi incision drainage (control group). The surgical time, intraoperative bleeding, postoperative pain, urination status, anal function evaluation, wound healing status and the clinical efficacy of the patient after 2 months of treatment were compared between the two groups.Results:The surgical time, intraoperative bleeding volume in the experimental group were lower than those in the control group: (18.70 ± 0.48) min vs. (38.10 ± 2.52) min, (32.35 ± 3.56) ml vs. (51.56 ± 6.24) ml, there were statistical differences ( P<0.05). The postoperative pain, urination status, anal function evaluation in the experimental group were better than those in the control group. In the experimental group, multiple incision drainage had a greater impact on patients and the wound healing cycle was longer. After treatment for 2 months, the total effective rate in the experimental group was better than that in the control group: 100.00%(47/47) vs. 91.67%(44/48), there was statistical difference ( χ2 = 4.09, P<0.05). Conclusions:Patients with high perianal abscess and treated with small incision floating line drainage has a shorter wound healing cycle, less pain, lower anal damage, and better clinical efficacy.
