Objective To evaluate the safety of the low glucoside composites of Epimedii Folium and clarify the pharmacokinetic characteristics of its five low glucosides.Methods Four groups of KM mice were orally administrated of corn oil,1 968,2 625 and 3 500 mg·kg-1 low glucoside composites of Epimedii Folium,respectively.Then,the living conditions,toxic symptoms,and death of the mice were observed for 7 consecutive days.After the mice were dissected,the viscera/body ratio and the viscera/brain ratio were calculated.Besides,the contents of alanine aminotransferase(ALT)and aspartate transaminase(AST)in plasma were determined by ELISA,and the pathological changes of the liver were observed by HE staining.C57BL/6J mice were intravenously or orally administered of baohuoside I,baohuoside II,sagittatoside A,sagittatoside B and sagittatoside C.Then,blood samples were collected at different time points.The plasma concentrations of the five low glucosides were measured by UHPLC-MS/MS.Results When compared with the control group,no significant differences were found in the body mass,viscera/body ratio,viscera/brain ratio,contents of ALT and AST in plasma after oral administration of different doses of low glucoside composites to mice.Moreover,no pathological changes or damages were found in the liver sections.After intravenous injection,the AUC0-t values of baohuoside Ⅰ,baohuoside Ⅱ,sagittatoside A,sagittatoside B and sagittatoside C in mice were 4.82,82.54,276.64,88.77 and 178.02 min·μg·mL-1,respectively.Meanwhile,the t1/2 values were 60.42,115.27,67.63,131.61 and 129.87 min,respectively.After oral administration,the AUC0-t values of the five low glucosides were 31.64,18.59,3.48,2.41 and 2.42 min·μg·mL-1,respectively.The Cmax values were 147.23,86.76,15.58,24.34 and 26.12 ng·mL-1,respectively.The tmax values were 21.00,78.00,78.00,30.00 and 28.00 min,respectively.The bioavailability of baohuosideⅠ,baohuosideⅡ,sagittatoside A sagittatoside B and sagittatoside C were 1.91%,0.51%,0.05%,0.06%and 0.04%,respectively.Conclusion The low glucoside composites of Epimedii Folium has high safety,and no hepatotoxicity were observed at dose of 3 500 mg·kg-1.The 5 low glucosides are quickly absorbed and rapidly eliminated in mice,and all of them have low bioavailability.

Ovarian cancer, notable for its severe prognosis among gynecologic cancers, has seen substantial progress in treatment approaches recently. Enhanced protocols in chemotherapy and the introduction of poly (ADP-ribose) polymerase (PARP) inhibitors for maintenance therapy have markedly improved outcomes for patients with specific genetic profiles, such as those positive for BRCA mutations or exhibiting homologous recombination deficiency (HRD). Additionally, the method of intraperitoneal chemotherapy administration has emerged as a valuable alternative to traditional transvenous routes, showing promise for wider clinical adoption. The field of surgery has also evolved, with increasing exploration into the benefits and feasibility of laparoscopic methods over more invasive traditional surgeries, aiming for complete tumor removal but with reduced patient impact. The hereditary nature of ovarian cancer underscores the importance of genetic testing, which has become integral in tailoring treatment strategies, particularly in determining suitability for PARP inhibitors.The formation of the East Asian Gynecologic Oncology Trial Group (EAGOT) aims to optimize treatment across Japan, Korea, China, and Taiwan. The ovarian cancer committee of EAGOT shared the current policies, focusing on 5 topics: 1) strategies for maintenance therapy after initial surgery and chemotherapy, 2) drug regimens for platinum-sensitive and platinum-resistant recurrence, 3) intraperitoneal chemotherapy, 4) laparoscopic surgery as an alternative to laparotomy, and 5) current status of genetic testing (BRCA, HRD, and panel tests) for ovarian cancer and its prospects. EAGOT’s multi-national trials aim to harmonize these evolving treatment strategies, ensuring that the latest and most effective protocols are accessible across the region, thereby significantly impacting patient outcomes in East Asia.

Objective:To explore the relationship between hematocrit, early fluid therapy, and clinical outcomes in patients with septic shock, and to provide evidence for fluid resuscitation therapy and prognosis assessment in these patients.Methods:The clinical information of patients with septic shock who were diagnosed and treated in the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2018 to December 31, 2020 were collected. Taking the survival or death of patients 28 days after admission as the end point of clinical research, the patients were divided into the survival and death groups. After analyzing the basic data of the two groups, the univariate and multivariate COX regression analyses were used to analyze the evaluation value of Δ Hematocrit (HCT) d2-d1 and ΔHCT d3-d1 on the prognosis of patients with septic shock. At the same time, the Kaplan-Meier survival curve was used to analyze the overall survival rate of patients with septic shock, and the smooth curve fitting graph was used to verify its relationship with net fluid intake and death. Results:There were 241 cases in the survival group and 67 cases in the death group. Univariate COX analysis showed statistically significant differences between the survival and death groups in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) ( P=0.0006), red cell volume distribution width (RDW) ( P=0.0043), age ( P=0.0184), ΔHCT d2-d1 ( P=0.0136), ΔHCT d3-d1 ( P=0.0204), and white blood cell (WBC) ( P=0.0444). Multivariate COX analysis showed that ΔHCT d2-d1 ( P=0.0115) and ΔHCT d3-d1 ( P=0.0029) were independent risk factors for death in EICU patients with septic shock. ΔHCT d2-d1 and ΔHCT d3-d1 were divided into three groups according to the three-digit method. The Kaplan-Meier survival curve showed no significant difference among the three groups in the overall survival rate related to ΔHCT d2-d1 ( P=0.16), but there was a statistically significant difference in the overall survival rate among the three groups related to ΔHCT d3-d1 ( P=0.025). The smooth fitting curve of ΔHCT d3-d1, net fluid intake, and prognosis showed that ΔHCT d3-d1 was negatively correlated with net fluid intake, and the middle ΔHCT d3-d1 group had the best prognosis. Conclusions:The value of ΔHCT d3-d1 is related to the net fluid intake of patients with septic shock. An appropriate decrease in HCT on the third day can improve the prognosis of patients with septic shock. The dynamic changes of hematocrit can provide a certain basis for fluid resuscitation and prognosis evaluation in patients with septic shock.

The obstruction of post-insulin receptor signaling is the main mechanism of insulin-resistant diabetes. Progestin and adipoQ receptor 3 (PAQR3), a key regulator of inflammation and metabolism, can negatively regulate the PI3K/AKT signaling pathway. Here, we report that gentiopicroside (GPS), the main bioactive secoiridoid glycoside of Gentiana manshurica Kitagawa, decreased lipid synthesis and increased glucose utilization in palmitic acid (PA) treated HepG2 cells. Additionally, GPS improved glycolipid metabolism in streptozotocin (STZ) treated high-fat diet (HFD)-induced diabetic mice. Our findings revealed that GPS promoted the activation of the PI3K/AKT axis by facilitating DNA-binding protein 2 (DDB2)-mediated PAQR3 ubiquitinated degradation. Moreover, results of surface plasmon resonance (SPR), microscale thermophoresis (MST) and thermal shift assay (TSA) indicated that GPS directly binds to PAQR3. Results of molecular docking and cellular thermal shift assay (CETSA) revealed that GPS directly bound to the amino acids of the PAQR3 NH₂-terminus including Leu40, Asp42, Glu69, Tyr125 and Ser129, and spatially inhibited the interaction between PAQR3 and the PI3K catalytic subunit (P110α) to restore the PI3K/AKT signaling pathway. In summary, our study identified GPS, which inhibits PAQR3 expression and directly targets PAQR3 to restore insulin signaling pathway, as a potential drug candidate for the treatment of diabetes.

Objective:To investigate the status and influencing factors of health-promoting lifestyle in young and middle-aged people with high normal blood pressure, so as to provide the basis for primary prevention about hypertension.Methods:From July to December 2020, a convenience sampling method was used to select 280 cases of young and middle-aged people with high normal blood pressure in the First Affiliated Hospital of Wenzhou Medical University were investigated by self-administered general information questionnaire,and Health Promotion Lifestyle Profile Ⅱ(HPLP-Ⅱ).Results:The HPLP-Ⅱ total score in the young and middle-aged with high normal blood pressure was 146.79 ± 29.57. Multiple linear regression analysis showed that different occupation,income, family history of hypertension and learning-willingness were the influencing factors of their health-promoting lifestyle( P<0.05). Conclusions:The health-promoting lifestyle among the young and middle-aged with high normal blood pressure is at a medium level, health care providers should strengthen guidance to improve their health-promoting lifestyle through health education and other ways for individuals without stable employment, poor income level, no family history of hypertension and lack in willingness to learn.

Objective:To investigate the role of growth arrest specific protein 6 (Gas6) in regulating macrophage polarization in wound healing.Methods:Clean male B6 mice were randomly(random number) divided into the normal group, skin defect group, skin defect group + normal saline group (PBS group), skin defect + Gas6 (1 μg) group, skin defect + Gas6 (5 μg) group, and skin defect + Gas6 (10 μg) group. Ten mice in each group were used to observe the healing of skin wounds. Macrophages were isolated from the wound tissues of the remaining 6 mice on the fifth day after modeling. The levels of IL-6 and IL-10 were detected by enzyme-linked immunosorbent assay (ELISA), the mRNA expression levels of arginase-1 (Arg-1) and inducible nitric oxide synthase (iNOS) were detected by RT-PCR, and flow cytometry was used to detect the expression of M1 marker CD197, M2 marker CD163 and F4/80. HE staining was used to detect the pathological changes of skin wounds. Masson staining was used to analyze the granulation tissue and collagen deposition.Results:Scab began to form on the surface of the wound on the third day after the skin defect model was established. The wound area of the Gas6 treatment group was smaller than that of the PBS group, and the wound healing was better than that of the PBS group. Compared with the normal group, the proportion of CD197 in macrophages of the skin defect group was significantly increased ( P=0.00 49), the proportion of CD163 and F4/80 double positive was significantly decreased ( P=0.00 86), the level of IL-6 was significantly increased ( P=0.00 13), the level of IL-10 was significantly increased ( P=0.00 14), the level of iNOS mRNA was significantly increased ( P=0.00 8), and Arg-1 was significantly increased in the skin defect group The mRNA level was significantly decreased ( P=0.01 21), and the inflammatory infiltration was aggravated. Compared with the PBS group, the proportion of CD197 in the Gas6 treatment group was significantly decreased ( P=0.00 0), the double positive rates of CD163 and F4/80 were significantly increased ( P = 0.00 0), the level of IL-6 was significantly decreased (P = 0.00 0), the level of IL-10 was significantly increased ( P=0.00 03), the level of iNOS mRNA was significantly decreased ( P=0.00 18), the level of Arg-1 mRNA was significantly increased ( P=0.00 1), and the number of inflammatory cells and the number of collagen fibers were increased. Conclusions:Gas6 can promote the transformation of macrophages from M1 to M2 in mice with skin defect, which is beneficial to the wound healing of skin defect.

The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk of being infected with the coronavirus and are more likely to develop severe complications, as compared to the general population. The increasing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Concerted efforts should be put into managing gynecological malignancies in an orderly manner by strictly implementing the measures that are specifically developed for controlling the spread of COVID-19. We have drafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemic based on our experience on controlling COVID-19 pandemic in China. We recommend that patients with gynecological malignancies should be managed in hierarchical and individualized manners in combination with local conditions related to COVID-19. Medical care decision should be balanced between controlling COVID-19 pandemic spread and timely diagnosis and treatment for gynecologic oncology patients.
