Abstract
1. The ferritin heavy chain (FHC) has a vital impact on follicular development in geese, due to its ability to regulate apoptosis of granulosa cells (GCs) and follicular atresia. However, its specific regulatory mechanisms remain unclear. The present study characterised how FHC regulates oxidative stress, cell proliferation and apoptosis in goose GCs by interfering with and overexpressing the FHC gene.2. After 72 h of interference with FHC expression, the activity of GCs decreased remarkably (p < 0.05), reactive oxygen species (ROS) levels and the expression levels of antioxidant enzyme genes catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) increased significantly (p < 0.05). The overexpression of FHC for 72 h was found to significantly reduce the expression of CAT and SOD genes (p < 0.05).3. Interfering with FHC expression revealed that the expression levels of the cell proliferation gene Aurora kinase A (AURORA-A) were significantly decreased (p < 0.05), while the expression levels of the apoptosis genes B-cell lymphoma-2 (BCL-2) and cysteine aspartate-specific protease 8 (CASPASE 8) increased (p < 0.05). Further research has shown that, when interfering with FHC expression for 72 h, apoptosis rate increased by 1.19-fold (p < 0.05), but the current data showed a lower apoptosis rate after FHC overexpression by 59.41%, 63.39%, and 52.31% at three different treatment times (p < 0.05).4. In conclusion, FHC improved the antioxidant capacity of GCs, promotes GCs proliferation, and inhibits GCs apoptosis of ovarian follicles in Sichuan white geese.

Abstract
OBJECTIVE To construct a prediction model for fetal growth restriction (FGR) during the first trimester of pregnancy and evaluate its screening performance. METHODS This was a prospective cohort study of singleton pregnancies that underwent routine ultrasound screening at 11 to 13 + 6 weeks at the Affiliated Suzhou Hospital of Nanjing Medical University between January 2019 and April 2022. Basic clinical information, ultrasound indicators and serum biomarkers of pregnant women were collected. Fetal weight assessment was based on the fetal growth curve for the Southern Chinese population. FGR was diagnosed according to Delphi consensus criteria. Least absolute shrinkage and selection operator (lasso) regression was used to select variables for inclusion in the model. Discrimination, calibration and clinical effectiveness of the model were evaluated in training and validation cohorts. RESULTS A total of 1188 pregnant women were included, of whom 108 had FGR. Lasso regression identified seven predictive features, including history of maternal hypertension, maternal smoking or passive smoking, gravidity, uterine artery pulsatility index, ductus venosus pulsatility index and multiples of the median values of placental growth factor and soluble fms-like tyrosine kinase-1. The nomogram prediction model constructed from these seven variables accurately predicted FGR, and the area under the receiver-operating-characteristics curve in the validation cohort was 0.82 (95% CI, 0.74-0.90). The calibration curve and Hosmer-Lemeshow test demonstrated good calibration, and the clinical decision curve and clinical impact curve supported its practical value in a clinical setting. CONCLUSION The multi-index prediction model for FGR has good predictive value during the first trimester. © 2023 The Authors.

Abstract
BACKGROUND With the onset of the COVID-19 pandemic and the large uptake in virtual care in primary care in Canada, the care of patients with type 2 diabetes has been greatly affected. This includes decreased in-person visits, laboratory testing and in-person assessments such as blood pressure (BP). No studies have investigated if these changes persisted with pandemic progression, and it is unclear if shifts impacted patient groups uniformly. The purpose of this paper was to examine changes in diabetes care pre, early, and later pandemic across different patient groups. METHODS A repeated cross-sectional design with an open cohort was used to investigate diabetes care in adults with type 2 diabetes for a 6-month interval from March 14 to September 13 over three consecutive years: 2019 (pre-pandemic period), 2020 (early pandemic period), and 2021 (later pandemic period). Data for this study were abstracted from the University of Toronto Practice-Based Research Network (UTOPIAN) Data Safe Haven, a primary care electronic medical records database in Ontario, Canada. Changes in diabetes care, which included primary care total visits, in-person visits, hemoglobin A1c (HbA1c) testing, and BP measurements were evaluated across the phases of the pandemic. Difference in diabetes care across patient groups, including age, sex, income quintile, prior HbA1c levels, and prior BP levels, were assessed. RESULTS A total of 39,401 adults with type 2 diabetes were included in the study. Compared to the 6-month pre-pandemic period, having any in-person visits decreased significantly early pandemic (OR = 0.079 (0.076-0.082)), with a partial recovery later pandemic (OR = 0.162 (95% CI: 0.157-0.169). Compared to the pre-pandemic period, there was a significant decrease early pandemic for total visits (OR = 0.486 (95% CI: 0.470-0.503)), HbA1c testing (OR = 0.401 (95% CI: 0.389-0.413)), and BP measurement (OR = 0.121 (95% CI: 0.116-0.125)), with partial recovery later pandemic. CONCLUSIONS All measures of diabetes care were substantially decreased early pandemic, with a partial recovery later pandemic across all patient groups. With the increase in virtual care due to the COVID-19 pandemic, diabetes care has been negatively impacted over 1-year after pandemic onset.

Abstract
Objective: To explore the properties of gelatin-polyethylene glycol hydrogel loaded with silver nanoparticle (AgNP) Chlorella (hereinafter referred to as the composite hydrogel) and its effects on healing of infected full-thickness skin defect wounds in mice. Methods: The research was an experimental research. The simple gelatin-polyethylene glycol hydrogel (hereinafter referred to as the simple hydrogel) and the composite hydrogel were prepared, and the appearance and injectability of the two hydrogels were observed at 55 and 37 ℃, and under the irradiation of 808 nm near-infrared light, respectively. An electronic universal testing machine was employed to assess the tensile and compressive stress-strain properties of both types of hydrogels at room temperature. Additionally, the cyclic compressive stress-strain properties of the composite hydrogel were examined at 80% of the maximum compressive stress. Staphylococcus aureus or Escherichia coli solution was added to phosphate buffer solution (PBS), simple hydrogel, and composite hydrogel, respectively. The part of composite hydrogel containing Staphylococcus aureus or Escherichia coli solution was irradiated with near-infrared light for 5 minutes. After each sample was incubated for 6 h, the dilution plating method was used to detect and calculate the mortality rates of the two bacteria at 24 h of culture (n=5). The discarded foreskin tissue was taken from a 6-year-old healthy boy admitted to the Department of Urology of the First Affiliated Hospital of Naval Medical University for circumcision. Primary human fibroblasts (HFbs) were isolated using the enzyme extraction method, routinely cultured to the 3rd to 6th passages for subsequent cellular experiments. Composite hydrogel extracts with final mass concentrations of 100.0, 50.0, 25.0, 12.5, and 0 mg/mL were respectively prepared and used to culture HFbs, and the cell proliferation after 24 h of culture was detected using a cell counting kit 8 (n=3). A total of twenty 6-8 weeks old C57BL/6J female mice were utilized, and a full-thickness skin defect was surgically created on the back of each mouse. The wounds were infected with Staphylococcus aureus solution. The infected mice were divided into blank control group, simple hydrogel group, composite hydrogel group, and combined treatment group according to the random number table, and the wounds were treated with PBS, simple hydrogel, composite hydrogel, and composite hydrogel+light irradiation (under the irradiation of 808 nm near-infrared light for 5 min), respectively, with 5 mice in each group. On post injury day (PID) 0 (immediately after the first wound treatment), 3, 7, and 14, an overall assessment of wound exudation and healing were conducted, and the wound healing rates on PID 7 and 14 were calculated (n=5). On PID 14, hematoxylin-eosin staining was performed to observe histopathological changes in the mouse wound. Results: Both simple hydrogel and composite hydrogel were in a solution state at 55 ℃ and transition to a gel state when cooling to 37 ℃. After the two hydrogels were irradiated by near-infrared light, only the composite hydrogel reheated up and returned to the solution state again with injectability. The maximum tensile stress of the composite hydrogel was up to 301.42 kPa, with a corresponding strain of 87.19%; the maximum compressive stress was up to 413.79 kPa, with a corresponding strain of 91.67%, which was similar to the tensile and compressive properties of the simple hydrogel. After 10 compression cycles, the maximum compressive stress of the composite hydrogel still reached 84.1% of the first compressive stress. After 24 h of culture, the mortality rate of Staphylococcus aureus treated with simple hydrogel was significantly higher than that treated with PBS (P<0.05); the mortality rates of Escherichia coli and Staphylococcus aureus treated with composite hydrogel alone were significantly higher than those treated with simple hydrogel (P<0.05); the mortality rates of Escherichia coli and Staphylococcus aureus treated with composite hydrogel+light irradiation were significantly higher than those treated with composite hydrogel alone (P<0.05). After 24 h of culture, compared with that cultured in composite hydrogel immersion solution with final mass concentration of 0 mg/mL, the proliferation activity of HFbs cultured in composite hydrogel immersion solution with final mass concentrations of 25.0 and 50.0 mg/mL was significantly enhanced (P<0.05), while the proliferation activity of HFbs cultured in composite hydrogel immersion solution with final mass concentration of 100 mg/mL was significantly decreased (P<0.05). On PID 0 and 3, more purulent secretions were seen in the wounds of mice in blank control group and simple hydrogel group, while only a small amount of exudate was observed in the wounds of mice in composite hydrogel group, and no obvious infection was observed in the wounds of mice in combined treatment group. On PID 7 and 14, the wound healing rates of mice in simple hydrogel group were significantly higher than those in blank control group (P<0.05); the wound healing rates of mice in composite hydrogel group were significantly higher than those in simple hydrogel group (P<0.05); the wound healing rates in combined treatment group were significantly higher than those in composite hydrogel group (P<0.05). On PID 14, the wounds of mice in blank control group exhibited a high infiltration of inflammatory cells with no new epithelial layer observed; the wounds of mice in simple hydrogel group displayed a short length of newly formed epithelium with a small amount of inflammatory cells; the wounds of mice in composite hydrogel group exhibited continuous formation of new epithelium and a large amount of immature granulation tissue; the wounds of mice in combined treatment group showed continuous epithelialization with less immature granulation tissue. Conclusions: The prepared composite hydrogel exhibits excellent thermosensitivity, photothermal properties, and injectability, as well as excellent mechanical properties, antibacterial properties, and biocompatibility, and can promote the healing of infected full-thickness skin defect wounds in mice.

Abstract
Malignant tumors in children are one of the most important diseases that threaten the health and quality of life of children and are the second most common cause of death in children.With the continuous improvement and progress of treatment technology, the long-term survival rate of children with tumor has been significantly improved, but both the disease itself and the treatment can impair the immune function of children, which makes them vulnerable to various infectious diseases and secondary serious complications, and even become a source of infection, endangering the health of others. Vaccination is the most cost-effective measure to prevent infectious diseases. For children with normal immune functions, the benefits of vaccination usually outweigh the disadvantages. However, there is a lack of detailed data on the vaccination situation, efficacy and safety of vaccine use for such immunocompromised tumor survivors, and there are no authoritative and uniform vaccination recommendations. This article reviewed and summarized the literature and consensus of some domestic and foreign scholars on current status of post-treatment vaccination status, efficacy and safety of vaccination for children with tumors after treatment, with the aim of providing a reference for the practice in this field in China.

Abstract
OBJECTIVE To clarify the application effect of information-guided enteral nutrition-associated diarrhea (ENAD) management process in patients with chronic obstructive pulmonary disease (COPD) undergoing non-invasive assisted ventilation. METHODS A mixed cohort study of pre- and post-control was conducted. Thirty-nine patients with COPD who were admitted to the emergency intensive care unit (ICU) of Huzhou First People's Hospital from July 1, 2021 to July 31, 2022 were enrolled. Taking the completion of the software development of ENAD management software for critically ill patients on January 28, 2022 as the time node, 20 patients admitted from July 1, 2021 to January 28, 2022 were set as the control group, and 19 patients admitted from January 29 to July 31, 2022 were set as the observation group. The two groups of patients received the same enteral nutrition support treatment, and the control group implemented the conventional ENAD treatment process with enteral nutrition intolerance disposal process as the core. On the basis of the control group, the observation group implemented the information-guided ENAD treatment process, and the system software actively captured the information of ENAD patients and reminded the medical team to improve the patient's diarrhea-related examination and provide alternative treatment plans. The duration of antidiarrhea, feeding interruption rate, and energy and protein intake, blood biochemical indexes, incidence of abnormal blood electrolyte metabolism, daily continuous non-invasive assisted ventilation and endotracheal intubation after 7 days of targeted diarrhea intervention were compared between the two groups. RESULTS Except for the basal pulse rate, there were no significant differences in gender distribution, age, and vital signs, basic nutritional status, arterial blood gas analysis and blood biochemistry at admission between the two groups, indicating comparability between the two groups. When ENAD occurred, the patients in the observation group obtained earlier cessation of diarrhea than those in the control group [days: 3.00 (2.00, 3.25) vs. 4.00 (3.00, 5.00), P < 0.01], and the feeding interruption rate was significantly lower than that in the control group [10.53% (2/19) vs. 65.00% (13/20), P < 0.01]. After 7 days of diarrhea intervention, the energy intake of the observation group was significantly higher than that of the control group [kJ×kg-1×d-1: 66.28 (43.34, 70.36) vs. 47.88 (34.60, 52.32), P < 0.01], the levels of hemoglobin (Hb), albumin (Alb) and serum prealbumin (PAB) were significantly higher than those in the control group [Hb (g/L): 119.79±10.04 vs. 110.20±7.75, Alb (g/L): 36.00 (33.75, 37.25) vs. 31.00 (30.00, 33.00), PAB (mg/L): 155.79±25.78 vs. 140.95±14.97, all P < 0.05], the daily continuous non-invasive assisted ventilation duration was significantly shorter than that of the control group [hours: 14 (12, 16) vs. 16 (14, 18), P < 0.01], and the arterial partial pressure of carbon dioxide (PaCO2) was significantly lower than that of the control group [mmHg (1 mmHg ≈ 0.133 kPa): 66.00 (62.00, 70.00) vs. 68.00 (67.50, 70.05), P < 0.05]. However, there were no significant differences in protein intake, incidence of abnormal electrolyte metabolism, and incidence of endotracheal intubation due to acute respiratory failure between the two groups. CONCLUSIONS The information-guided ENAD treatment process can enable the COPD patients undergoing continuous non-invasive assisted ventilation who experience ENAD to receive earlier cessation of diarrhea, and improve the protein energy metabolism and respiratory function of the patients.

Abstract
Objective: To investigate the association between chronic lung diseases and the risk of lung cancer. Methods: Using UK Biobank (UKB) survey data, 472 397 participants who had not previously been diagnosed with cancer and whose self-reported sex was consistent with their genetic sex were studied. Information on the prevalence of previous chronic lung diseases, general demographic characteristics and the prevalence of lung cancer was collected using baseline questionnaires and national health system data. The multivariate Cox proportional risk regression model was used to analyze the association between four previous chronic lung diseases (asthma, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and interstitial pulmonary disease) and the risk of lung cancer. A total of 458 526 participants with genotype data in the observational study were selected as research objects, and the closely related and independent genetic loci with four chronic lung diseases were selected as instrumental variables, and the association between four chronic lung diseases and the risk of lung cancer was analyzed by Mendelian randomization (MR). The dose-response relationship between genetic risk score and the risk of lung cancer in different chronic lung diseases was evaluated using a restricted cubic spline function. Results: The age [M (Q1, Q3)] of the subjects was 57 (50, 63) years old, and there were 3 516 new cases of lung cancer (0.74%) during follow-up. The multivariate Cox proportional hazard regression model analysis showed that previous chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis were associated with the risk of lung cancer, about 1.61 (1.49-1.75) and 2.61 (1.24-5.49), respectively. MR Studies showed that genetically predicted chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis were associated with the risk of lung cancer, with HR (95%CI) of 1.10 (1.03-1.19) and 1.04 (1.01-1.08), respectively. The results of restricted cubic spline function analysis showed that the risk of lung cancer increased linearly with the increase of genetic risk scores for chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis (P<0.05). Neither observational studies nor Mendelian randomization analysis found an association between previous asthma or interstitial lung disease and the risk of lung cancer (both P values>0.05). Conclusion: Chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis are potential risk factors for lung cancer.

Abstract
Introduction Sepsis, an infection with multiorgan dysfunction, is a serious burden on human health. Berberine (BBR), a bioactive component, has a protective effect on sepsis and the effect may be related to gut microbiota. However, studies on the role of BBR with gut microbiota in sepsis are lacking. Therefore, this study investigated the ameliorative effects and the underlying mechanisms of BBR on cecal ligature and puncture (CLP) rats. Methods This study has observed the effect of BBR on pathological injury, Inflammation, intestinal barrier function, gut microbiota, and metabolite change in CLP rats by Hematoxylin-eosin staining, enzyme-linked immunosorbent assays, flow cytometry, 16S rDNA, and metabolomics analyses. Results The inhibition effects of BBR treatment on the histological damage of the lung, kidney, and ileum, the interleukin (IL)-1b, IL-6, IL-17A, and monocyte chemokine-1 levels in serum in CLP rats were proved. Also, the BBR inhibited the diamine-oxidase and fluorescein isothiocyanate-dextran 40 levels, suggesting it can improve intestinal barrier function disorders. The cluster of differentiation (CD) 4+, CD8+, and CD25+ Forkhead box protein P3 (Foxp3) + T lymphocytes in splenocytes were up-regulated by BBR, while the IL-17A+CD4+ cell level was decreased. The abundance of gut microbiota in CLP rats was significantly different from that of the sham and BBR treatment rats. The significantly changed metabolites in the serum mainly included carbohydrates, phenols, benzoic acids, alcohols, vitamins et al. Additionally, this study predicted that the biological mechanism of BBR to ameliorate sepsis involves glycolysis-, nucleotide-, and amino acid-related metabolic pathways. Discussion This study proved the strong correlation between the improvement effect of BBR on sepsis and gut microbiota and analyzed by metabolomics that gut microbiota may improve CLP rats through metabolites, providing a scientific basis for BBR to improve sepsis and a new direction for the study of the biological mechanism.

Abstract
INTRODUCTION Ultrasound has long been the radiological investigation of choice for right upper quadrant pain in the detection of gallstones and cholecystitis. However, previously reported sensitivity, specificity and other diagnostic metrics have varied widely and the underlying patient numbers have been small. We present robust and exhaustive diagnostic metrics based on a large series of 795 patients. METHODS All laparoscopic cholecystectomies at Portsmouth Hospitals University were prospectively logged between 2017 and 2020. Ultrasound findings, Nassar operative difficulty and histopathological findings were all collected in addition to patient biometrics. RESULTS In our large patient series, the sensitivity of ultrasound for cholecystitis was lower than previously reported at 75.7% for acute cholecystitis, 34.6% for chronic cholecystitis and 42.7% overall. Moreover, we show that sensitivity degrades with the time between ultrasound and cholecystectomy, falling below 50% at 140 days. Finally, we show that ultrasound strongly predicts the Nassar difficulty grade of cholecystectomy and that its ability to do so is greatest when the interval between ultrasound and cholecystectomy is less than 27 days. CONCLUSIONS We present robust diagnostic metrics for ultrasound in the diagnosis of cholecystitis. These should caution the clinician that ultrasound may miss a quarter of cases of acute cholecystitis and over half of all cases of cholecystitis. Conversely, the finding of a thickened gallbladder wall on ultrasound can predict a 'difficult cholecystectomy' and highlight the need for appropriate expertise and resources. Both this prediction and the diagnostic sensitivity are best if the ultrasound is done less than 27 days before cholecystectomy.

Abstract
AIM To assess the rates of breast cancer detected in postoperative surveillance mammograms in women >70 Years and overall mortality in this age group. MATERIALS AND METHODS Four hundred and ninety-eight patients were identified retrospectively from a database from a single large UK hospital. Patients were included in the study if they were female, aged >70 years at diagnosis of either invasive breast cancer or ductal carcinoma in situ (DCIS), had surgical treatment between 1 January 2010 and 31 December 2014, and no previous diagnosis of breast cancer. Statistical analysis was performed using Excel, using the X2 test, with p ≤ 0.05 considered statistically significant. RESULTS The mean age of women included in this study was 77 years. The mean number of postoperative surveillance mammograms performed per patient was 4.2. In the 5-year follow-up, there was a local recurrence rate of 1.9% (n=6) and a contralateral breast cancer rate of 1% (n=6). The 5-year overall mortality rate was 17.7% (n=88), and the 5-year breast cancer-specific mortality rate was 7.2% (n=36). CONCLUSION This study demonstrated low local recurrence and contralateral breast cancer rates during the 5-year follow-up period. Clear discussions therefore need to be held with older patients about the value of postoperative mammographic surveillance. Further research is required regarding patient opinion and experience to help develop more consistent guidelines.

Abstract
Wound repair has always been one of the key issues of clinical concern. In recent years, negative pressure wound therapy (NPWT) has played an increasingly active role in promoting various wound repairs, not only for the treatment of common acute and chronic wounds, but also for closure of surgical incisions, preparation of wounds before skin transplantation, fixation of skin grafts after transplantation, and treatment of some complex thoracic and abdominal trauma. This review aims to summarize the clinical application of NPWT in wound treatment and the related latest research progress, and to preliminarily discuss its future development prospects.

Abstract
Objective: To investigate the clinicopathological features, diagnosis, treatment and prognosis of simultaneous double primary gynecological malignant tumors. Methods: A total of 23 patients with simultaneous double primary malignant tumors of female reproductive system primarily treated in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 1, 2010 to December 31, 2020 were retrospectively collected. The age, symptoms, tumor stage, tumor type, treatment and prognosis of patients were collected and followed up. Results: (1) The number of patients with gynecological tumors in our hospital increased year by year in the past 11 years. A total of 8 987 patients with gynecological malignant tumors were firstly diagnosed and cured in our hospital, including 3 474 cases of cervical cancer, 3 484 cases of endometrial cancer, 1 329 cases of ovarian malignancies, 171 cases of fallopian tube cancer, 182 cases of uterine sarcoma, 42 cases of vaginal cancer, 192 cases of vulvar cancer, 110 cases of trophoblastic tumor and 3 cases of other gynecological malignancies. The top three cancers were endometrial cancer, cervical cancer and ovarian malignancies. (2) There were 23 patients identified with simultaneous double primary gynecological tumors in the past 11 years, accounting for 0.26% (23/8 987) of female malignant tumors. There were 3 cases of cervical cancer complicated with endometrial cancer, 3 cases of cervical cancer complicated with ovarian cancer, 16 cases of endometrial cancer combined with ovarian cancer, and 1 patient with endometrial cancer combined with fallopian tube cancer. (3) All 23 patients underwent surgical treatment. According to the first diagnosis of the tumor, the surgical methods included cervical cancer radical surgery, endometrial cancer staging surgery and ovarian cancer cytoreductive surgery. After operation, radiotherapy and chemotherapy were supplemented according to the results of pathological examination and tumor staging. (4) The age of 23 patients ranged from 28 to 66 years, with an average age of (49.4±9.7) years. All patients had vaginal bleeding or conscious pelvic mass as their main clinical manifestation. The clinical stage was found in 7 patients (30%, 7/23) with advanced gynecological cancer (stage Ⅲ-Ⅳ), and 16 patients (70%, 16/23) with early stage gynecological cancer (stage Ⅰ-Ⅱ). According to the nonspecific tumor markers, 13 patients (57%, 13/23) had elevated CA125 and CA199. (5) Among the 23 patients, 1 case was uncontrolled and 3 cases recurred during the follow-up period, and the sites of uncontrolled or recurred were all located in the abdominopelvic cavity. Three cases died. Among the 3 patients who died, 1 patient was an uncontrolled patient, whose tumor type was cervical adenosquamous cell carcinoma combined with ovarian clear cell adenocarcinoma. The overall survival time was 19 months with postoperative supplementary radiotherapy and chemotherapy. There were 2 recurrent patients, and the tumor types were endometrioid carcinoma complicated with high-grade serous ovarian carcinoma and ovarian endometrioid carcinoma, respectively. After surgery, all patients received supplementary chemotherapy and recurred 60 and 21 months after surgery, respectively, and the overall survival time was 78 and 28 months, respectively. Another patient recurred 43 months after surgery, and survived with tumor for 14 months after recurrence. The remaining 19 patients were tumor-free and were still being followed up. Conclusions: There are no specific markers for simultaneous double primary gynecological malignant tumors. The most common clinical symptoms are vaginal bleeding or pelvic mass. The treatment principle of simultaneous double primary gynecological malignant tumor is the same as that of single gynecological malignant tumor, but need to be taken into account the characteristics of two tumors. Surgery is the main treatment method, and radiotherapy and chemotherapy play an important auxiliary role. The prognosis of simultaneous double primary gynecological malignancies is related to the late stage of the two malignancies.

Abstract
INTRODUCTION The contribution of periodontal disease to adverse systemic consequences remains controversial. This analysis examined 2 well-investigated conditions independently and combined-adverse pregnancy outcomes and glycemic control for patients with diabetes-based on shared pathogenic mechanisms of periodontal infection and inflammation. It was proposed that inconsistencies in study design significantly contribute to outcome discrepancies found between periodontal intervention studies undergoing meta-analysis. METHODS Meta-analyses evaluating periodontal interventions on the rate of preterm birth and changes in glycated hemoglobin A1c in type 2 diabetes populations were conducted based on a systematic review of randomized controlled trials. Meta-regression covariates for exploring heterogeneity included sample size, level of medical management, and bias risk as moderator variables in a random-effects meta-regression. RESULTS Systematic review identified 17 studies of diabetes and 13 of pregnancy outcomes. Analyses of these studies identified 0.50% reduction in HbA1c and 0.78 odds ratio for preterm births. The heterogeneity associated with the models was high (I2 = 92.4 and I2 = 62.7%, respectively). The adjusted models evaluating each systemic condition separately accounted for 52.2% of the effect for diabetes and 81.4% for pregnancy outcome effects independently, and 63.5% collectively, across interventional studies. CONCLUSION This systematic review with meta-regression analysis of heterogeneity demonstrates that disparate results seen in randomized controlled trials of periodontal therapy affecting systemic outcomes may be explained in large part by study design, specifically stringency in consideration of medical management and sample size. The potential for confounding factors to influence outcomes remains a concern in understanding the implications of oral health on systemic conditions. KNOWLEDGE TRANSFER STATEMENT The findings of this study demonstrate that much of the benefits seen from periodontal therapy on adverse systemic outcomes for diabetes and pregnancy are due to limitations in study design.

Abstract
Continuous chest compressions during the transportation of patients with cardiac arrest have always been a difficult part in the field of pre-hospital emergency cardiopulmonary resuscitation (CPR). How to ensure continuous high-quality chest compressions is an important part of the patient's entire rescue process. At present, mechanical compression devices are commonly used to provide continuous high-quality chest compressions during the transportation. However, the installation process of the mechanical compression device involves posture changes of the patient, the placement of the device base, etc., and it is very likely to affect the continuous high-quality CPR treatment in the pre-hospital emergency process with limited human resources. Therefore, the First Affiliated Hospital of Huzhou University and Huzhou University jointly designed a rescue stretcher dedicated for CPR mechanical compression device, and has obtained the national utility model patent (ZL 2019 2 1005444.9). The main design feature of this stretcher is that the base of the compression device is combined with the stretcher, which eliminates the installation and fixation process of the base during the installation of the mechanical compression device, shortens the installation time. It has certain clinical applications value.

Abstract
Objective: To investigate the mechanism of diallyl sulfide (DAS) on paraquat (PQ) - induced acute lung injury in rats. Methods: In May 2016, 32 adult male Wistar rats were randomly divided into control group, model (PQ) group, DAS treatment group and dexamethasone (DXM) treatment group, with 8 rats in each group. PQ poisoning model was established by intragastric administration of PQ solution (70 mg/kg) . 100 mg/kg DAS (DAS treatment group) , normal saline (control group and PQ group) and 1 mg/kg DXM (DXM treatment group) were injected intraperitoneally before and after modeling. After 24 hours, the rats were killed and the degree of lung injury was observed. The expression of inducible nitric oxide synthase (iNOS) in lung tissue was measured. Alveolar macrophages were isolated and cultured. The supernatant was taken to determine the content of NO, and the expressions of iNOS mRNA in alveolar macrophages were detected. Results: Compared with the control group, the pathological injury score and the expression of iNOS in the lung tissue of PQ group were significantly increased, and the content of NO secreted by alveolar macrophages and the expression of iNOS mRNA were significantly increased (P<0.05) . Compared with PQ group, the pathological injury scores and the expressions of iNOS in lung tissue of rats in DAS treatment group and DXM treatment group were significantly decreased, and the contents of NO secreted by alveolar macrophages and the expressions of iNOS mRNA were significantly decreased (P<0.05) . There was no significant difference between DXM group and DAS group (P>0.05) . Conclusion: DAS may have protective effect on acute lung injury induced by PQ in rats.
