Objective:To analyze the survival outcomes and prognostic factors of patients with ovarian carcino-sarcoma(OCS)based on SEER database.Methods:The data of 1285 OCS patients from 2000 to 2018 in SEER database were retrospectively analyzed.Univariate and multivariate Cox proportional hazards models were used to evaluate the prognostic factors associated with overall survival(OS)and cancer specific survival(CSS).Kap-lan-Meier survival curve was drawn to evaluate the survival analysis of patients' prognosis after clinical treatment.Results:①The study cohort included a total of 1285 OCS patients,The mean age of these patients was 66.21±11.71 years.Most patients had already experienced regional(22.80％)or distant(72.22％)metastasis at the time of diagnosis.②Multivariate Cox regression revealed,SEER stage of regional or distant metastasis,no surger-y,no chemotherapy,and no lymphadenectomy were independent risk factors for both patient OS and CSS(HR＞1,P＜0.05).Age ≥67 years was an independent risk factor for OS(HR＞1,P＜0.05).Age ≥ 83 years was an in-dependent risk factors for CSS(HR＞1,P＜0.05).③Kaplan-Meier survival analysis showed that among surgical patients with adjacent tissue invasion or distant metastasis had significantly better overall survival rate after lymph node dissection than those without(P＜0.001);We didn't see the significantly different effects of lymphadenecto-my on patients with localized disease(P=0.266).Among all patients who underwent surgery,the overall survival rate of all patients who received adjuvant chemotherapy after surgery was significantly better than that of those who did not(P＜0.001).Conclusions:Prognosis of OCS patients is associated with age,SEER comprehensive stage,surgery status,chemotherapy status,lymphadenectomy status.Patients with OCS who underwent cytore-ductive surgery and adjuvant chemotherapy had a better prognosis.However,it is questionable whether lymph-adenectomy is necessary in OCS patients with very early stage.

Objective To compare the efficacy and tolerability of the novel bowel-cleansing agent TCIC-001 and the traditional polyethylene glycol (PEG) regimen for bowel preparation prior to colonoscopy. Methods Prospective inclusion of 62 patients who were scheduled to undergo colonoscopy at Zhongshan Hospital, Fudan University from July 2021 to July 2022. They were randomly divided into TCIC-001 group (n=31) and PEG group (n=31) using a random number table method. The TCIC-001 group took TCIC-001 orally, drinking water in stages, with a total liquid intake of 1 500 mL; the PEG group took PEG orally, taking it in 4 doses, with a total liquid intake of 3 000 mL. The primary endpoint indicator is the quality of intestinal hygiene evaluated by the Boston Bowel Preparation Scale (BBPS), the secondary endpoint indicators were medication adherence, medication duration, frequency of bowel movements, duration of bowel movements, and incidence of adverse events between two groups. Results No significant differences were observed in sex, age, or defecation frequency between the two groups. For efficacy, both groups achieved equivalent bowel cleanliness, with a “good preparation” rate of 93.55% and comparable BBPS score of each intestinal segment and total scores. For tolerability, the TCIC-001 group had a shorter medication duration compared to the PEG group ([48.8±25.9] min vs [82.8±28.4] min, P<0.001), a longer defecation duration ([288.6±74.0] min vs [236.5±74.3] min, P<0.001), and a lower incidence of first defecation before medication completion (9.68% vs 41.94%, P=0.004). Regarding safety, no significant differences were observed between the TCIC-001 group and the PEG group in incidences of chloride disturbances (0% vs 9.68%) and calcium disturbances (3.23% vs 6.45%), and no other adverse events. Conclusions TCIC-001 demonstrated comparable bowel-cleansing efficacy to PEG while significantly improving tolerability (reduced medication time and lower risk of premature defecation) and maintaining favorable safety.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.

Objective:To evaluate the efficacy and safety of a new plasma radiofrequency generator and a disposable mucosal incision knife for endoscopic submucosal dissection (ESD) of gastrointestinal lesions.Methods:This study is a prospective, randomized, non-inferiority multicenter study (Chinese Clinical Trial Registry No.: ChiCTR2000041394). The inclusion criteria for cases are as follows: (1) being able to understand and voluntarily participate in this clinical trial, and voluntarily signing the informed consent form; (2) being 18-70 years old, regardless of gender; (3) having a gastrointestinal lesion and meeting the endoscopic treatment conditions for the indications of endoscopic submucosal dissection (ESD). The exclusion criteria are: (1) meeting the contraindications for ESD; (2) having a surgical contraindication due to coagulation dysfunction or still taking anticoagulants 1 week before surgery; (3) having coagulation dysfunction, that is, the prothrombin time is prolonged by more than 3 seconds (more than 5 seconds in patients with liver disease), or the activated partial thromboplastin time is prolonged by more than 10 seconds, and the platelet count is < 70×10?/L; (4) having severe cardiopulmonary insufficiency and being unable to tolerate the surgery; (5) being a reproductive-aged woman with a positive blood or urine pregnancy test or a lactating woman; (6) the investigator deems that there are other factors that are not suitable for inclusion or affect the subject's participation. Patients who underwent ESD treatment for gastrointestinal lesions from March 2019 to April 2023 at the Endoscopy Center of Zhongshan Hospital Affiliated to Fudan University, the Department of Gastroenterology of Minhang District Central Hospital in Shanghai, and the Department of Gastroenterology of Quzhou People's Hospital were prospectively included. The experimental group used a new plasma radiofrequency therapy instrument and a disposable mucosal incision knife, while the control group used a high-frequency electrosurgical system and a disposable mucosal incision knife. The primary efficacy indicator was the en bloc resection success rate, the secondary efficacy indicators included the coagulation success rate, and the operation stability of the plasma radiofrequency therapy instrument and the disposable mucosal incision knife; the safety indicators included the incidence of intraoperative bleeding, intraoperative perforation, and postoperative complications. Results:The study cohort comprised 194 patients, 95 in the experimental group and 99 in the control group. Analysis of the full set showed rates of en bloc resection of 97.89% (93/95) and 96.97% (96/99) in the experimental and control groups, respectively; the difference being 0.53% (-5.58%, 6.64%). Analysis of the compliance set showed rates of en bloc resection of 97.83% (90/92) and 96.88% (93/96) in the experimental and control groups, respectively; the difference being 0.58% (-5.79%, 6.94%). These data indicate that the rate of en bloc resection in the experimental group using plasma radiofrequency therapy and disposable mucosal incision was not inferior to that of the control group. The rates of achieving intraoperative coagulation in the experimental and control groups were 7.14% (5/70) and 5.97% (4/67), respectively; this difference is not statistically significant ( P=1.000). The control group had a significantly better rate of using the same instruments throughout the procedure than did the experimental group ( P<0.001). In the safety analysis set, the incidences of intraoperative and postoperative adverse events did not differ significantly between the two groups (both P>0.05). Conclusion:Plasma radiofrequency therapy equipment and a disposable mucosal incision knife are safe and effective instruments for performing ESD of gastrointestinal lesions.

Oral health is an integral component of overall well-being,with the oral cavity serving as a channel for ex-ternal communication and expression of emotions such as stress and pessimism.Oral diseases can intensify feelings of depression,whereas depression can worsen oral health conditions.As a crucial part of the human microbiome,an imbal-ance in oral microbiota can release oral pathogenic microbes,which,through pathways including the circulation,ner-vous,and immune systems,can reach the brain and significantly affect the central nervous system.This can lead to dys-regulation of the hypothalamic-pituitary-adrenal(HPA)axis,further intensifying the development of depression.Similarly,an imbalance in oral microbiota in individuals with depression can intensify the occurrence of oral diseases.The rela-tionship between depression and oral diseases is not isolated but rather a complex interplay in which they mutually in-fluence and act as causative factors.To elucidate the causal relationship between oral diseases and depression and de-vise strategies for the prevention and treatment of both conditions,we explore the interaction mechanisms between oral diseases and depression from the perspective of oral microbiota.The occurrence of dental caries,periapical periodonti-tis,and periodontal diseases is closely associated with the excessive proliferation of specific bacteria in the oral cavity,such as Streptococcus mutans,Porphyromonas gingivalis,and Fusobacterium nucleatum.These bacteria can directly in-vade the brain through the compromised blood-brain barrier,activating pro-inflammatory cytokines and worsening de-pressive symptoms.Inflammatory conditions and ulcers in the oral mucosa are caused by various factors,including infec-tion and immune abnormalities.Because of compromised immune function in individuals with depression,these inflam-matory responses are often more severe and difficult to control.Malocclusion,trigeminal neuralgia,and temporomandibu-lar joint disorders increase the risk of depression because of psychological stress and changes in the immune system.We also outline the diagnostic and therapeutic considerations for oral diseases in patients with depression,emphasizing the importance of early intervention for disease management.Future research will explore the therapeutic potential of oral microbiota in individuals with depression,with the aim to improve symptoms and treatment outcomes by adjusting oral microbiota,thus providing novel avenues for the prevention and treatment of depression.
