Objective:To explore the clinical effect of the whole-process management scheme of daytime minimally invasive liver resection surgery based on the enhanced recovery after surgery (ERAS) concept.Methods:This is a retrospective case series study. The data of 55 patients who underwent minimally invasive daytime liver resection surgery under the ERAS concept at the Department of General Surgery,Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from January 2023 to August 2024. There were 22 males and 33 females;aged (48.2±15.1) years (range: 16 to 77 years). All patients were classified as Grade 2 according to the American Society of Anesthesiologists physical status classification. Among them, 7 cases were complicated with liver cirrhosis and 10 cases had fatty liver. A multidisciplinary team was formed, consisting of surgeons, anesthesiologists, rehabilitation physicians, psychologists, pharmacists, acute pain management team, operating room nurses, day surgery ward nurses, and ERAS specialized nurses. After strict evaluation by surgeons and anesthesiologists, patients suitable for daytime liver resection surgery were implemented with the ERAS whole-process management plan for liver resection on the basis of routine nursing care.Results:Among the 55 patients, 50 were discharged smoothly within 48 hours, while 5 were transferred to specialized departments for further treatment due to not meeting the discharge criteria, with a smooth daytime discharge rate of 90.9%. Among the 50 patients, 30 underwent laparoscopic surgery and 20 underwent robotic-assisted surgery. The surgery time was (91.6±28.2)minutes(range:45 to 165 minutes), with the intraoperative blood loss of only (30.5±25.5)ml(range:5 to 100 ml). Pathological examination results showed that among the 50 patients, 13 cases had hepatocellular carcinoma, 21 cases had hepatic hemangioma, 4 cases had hepatic cyst, 8 cases had focal nodular hyperplasia, 1 case had low-grade dysplastic nodule, 1 case had hepatolithiasis, 1 case had lymphoma, and 1 case had vascular, fibrous and lymphoid tissue proliferation. There were 44.0% patients who were able to get out of bed on the day of surgery. The hospital stay was (1.8±0.4)days(range:1 to 2 days), and the hospitalization cost was (34 499±20 330)yuan(range:11 724 to 73 488 yuan). No complications requiring special treatment outside the conventional pathway were observed during the hospital stay and follow-up period. At the 2-week outpatient follow-up, no significant abnormalities were found in all patients, and the wound healing was good.Conclusions:The daytime liver resection surgery based on the ERAS whole-process management plan has shown good feasibility in clinical practice. It helps to simplify medical process, shorten hospital stay, and reduce medical costs.

Liver cancers are characterized by high heterogeneity and complexity,posing significant challenges in early diagnosis and prognosis,which burden patients and healthcare systems.Blood metabolomics,an emerging system biology technology,analyzes small molecular metabolites in the blood to reveal metabolic features of tumors,offering novel insights for the early diagnosis and prognosis evaluation of liver cancers.In recent years,substantial progress has been made in identifying specific blood metabolic biomarkers for liver cancers,including hepatocellular carcinoma,intrahepatic cholangiocarcinoma,and metastatic liver cancer,laying the foundation for more precise personalized treatments.However,current studies face limitations such as small sample sizes,insufficient biomarker validation,and the need for standardization.Large-scale,multi-center studies and integrated multi-omics analyses are urgently required to optimize and validate the application of blood metabolomics.This review summarizes the current state of research on blood metabolomics in liver cancers,focusing on its potential and challenges in early diagnosis and prognosis prediction,aiming to provide insights into precision diagnosis and treatment of liver cancers.

Objective To analyze the characteristics,causes,influencing factors of compensation,and appraisal features of second-instance medical malpractice cases involving cardiovascular diseases in Henan Province from 2017 to 2022,and to provide reference for forensic appraisal and judicial trial.Methods Cases were retrieved from China Judgments Online between 2017 and 2022.A total of 1,957 documents were reviewed,including 1,397 medical malpractice cases and 130 cardiovascular disease cases.Results The total compensation awarded in these second-instance cases was 27.04 million yuan,with a median of 158,600 yuan.Cases involving patient death accounted for 80.00％(104/130).Among 107 cases with first-instance appraisals,55.14％(59/107)raised objections,while 74.62％(97/130)of the second-instance trials upheld the original judgment.The most common degree of responsibility borne by medical institutions was secondary responsibility(41.54％,54/130).The top three medical faults were:inadequate observation and management of patient conditions(46.15％),omission of auxiliary examinations(37.50％),and insufficient notification(36.54％).In terms of violations-including medical record documentation,inappropriate treatment,misdiagnosis or missed diagnosis,out-of-scope practice,and improper medication use-the actual proportions in judgments(24/113,34/113,12/113,7/113,14/113)were all significantly lower than the patients' claims(all P＜0.05).Conclusion Cardiovascular medical malpractice cases in second-instance trials involve substantial compensation and a high proportion of death outcomes.Both medical institutions and patients should pay greater attention to first-instance trials.Appraisal organizations should proactively provide explanation and education regarding issues likely to raise patient doubts,thereby reducing unnecessary appeals.They should also avoid hasty revisions of appraisal opinions when faced with objections and instead focus on improving the quality and credibility of appraisals.In determining medical faults,emphasis should be placed on evaluating whether there was inadequate patient monitoring and management,omission of auxiliary examinations,and insufficient notification.

Objective:To analyze vaginal microecological changes in patients with vaginal infectious diseases and their correlation with human papillomavirus (HPV) infection.Methods:A case-control study was conducted involving 416 patients who visited the Gynecology Outpatient Department and the Cervical Disease Clinic at Yongkang Maternity and Child Care Hospital between December 2022 and December 2023. All patients underwent testing for vaginal microecology and HPV to evaluate the prevalence of vaginal infectious diseases and HPV infection. Vaginal microecological indicators were compared between patients with vaginal infections and those without identifiable pathogenic bacterial dysbiosis. The indicators included microbial density, lactobacilli levels, pH, hydrogen peroxide levels, abnormal leukocyte esterase, and the grading of vaginal lactobacilli. Additionally, the HPV infection status was compared among patients with different vaginal microecological environments, and the correlation between vaginal infections and HPV infections was analyzed.Results:In a study involving 416 participants, 216 were diagnosed with vaginal infections, with an incidence rate of 51.92% (216/416). Among these cases, 118 were classified as a single infection, accounting for 54.63% (118/216), while 98 were identified as mixed infections, accounting for 45.37% (98/216). The rate of HPV infection among the 216 patients with vaginal infectious diseases was 37.04% (80/216). This rate was significantly higher than the 15.31% (30/196) observed in patients without identifiable pathogenic bacterial dysbiosis ( χ2 = 24.79, P < 0.001). Patients with vaginal infectious diseases also displayed elevated rates of abnormal lactobacilli levels, abnormal pH, abnormal leukocyte esterase, and abnormal lactobacilli grading, with rates of 59.26%, 86.57%, 72.69%, and 57.41%, respectively. In comparison, patients without identifiable pathogenic dysbiosis had rates of 31.12%, 18.88%, 51.53%, and 34.18%, respectively. All differences were statistically significant ( χ2 = 32.76, 86.83, 19.64, 22.28, all P < 0.001). Additionally, significant differences in HPV infection rates were observed among patients who tested positive for bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis when compared to those who tested negative ( χ2 = 12.46, 4.04, 6.14, P < 0.001, 0.044, 0.013). Both bacterial vaginosis and vulvovaginal candidiasis were recognized as high-risk factors for HPV infection ( OR = 4.039, 2.902, both P < 0.05). Conclusions:Vaginal infectious diseases are significantly linked to HPV infection, particularly bacterial vaginosis and vulvovaginal candidiasis. Analyzing the characteristics of the vaginal microbiota can enhance the clinical management of HPV infection.

Objective To investigate the effect of ethanolic extract of Cichorium glandulosum Boiss.et Huet.on fecal bile acid profiles in high-fat-diet-induced obese mice.Methods Twenty-four 6-week-old C57 BL/6 male mice were divided randomly into normal,model,drug-administration,and metformin groups.Mice in the normal group were fed a regular diet and mice in the other three groups were given high-fat diets.The drug-administration group was gavaged with 10 mL/kg ethanol extract of Cichorium glandulosum Boiss.et Huet.daily,and the metformin group was gavaged with 10 mL/kg metformin daily.After 10 weeks,livers were collected to measure hepatic total triglycerides(TG),total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),and high-density lipoprotein(HDL)-C.Feces were collected and analyzed.Results Body weight(P＜0.0001),liver TG(P＜0.05),and TC(P＞0.05)were all significantly higher in model mice compared with normal mice,while LDL-C(P＞0.05)and HDL-C(P＜0.001)were significantly lower,indicating abnormal weight gain and lipid metabolism.Alcoholic extract of Cichorium glandulosum Boiss.et Huet.significantly reduced body weight(P＜0.0001),liver TG(P＜0.0001),serum TG(P＜0.05),TC(P＜0.01),and LDL-C(P＜0.05)in mice.Methodsological validation showed that the current method could accurately quantify 52 bile acids in feces.Analysis of the concentration of each type of bile acid revealed that alcoholic extract of Cichorium glandulosum Boiss.et Huet.significantly increased the secondary/primary bile acid ratio(P＜0.05).Multivariate analysis showed that the bile acid metabolic pattern was significantly altered in all groups.Eight differential bile acids were screened in the drug-administration group relative to the model group using variable importance of projection＞1 and P＜0.05.A search of the Kyoto Encyclopedia of Genes and Genomes database revealed that the differential bile acids were mainly involved in the secondary bile acid biosynthesis pathway.Correlation analysis showed that four differential bile acids,deoxycholic acid(r,=0.6445,P＜0.001),isolithocholic acid(r,=0.5879,P＜0.01),3β-deoxycholic acid(r,=0.6649,P＜0.001),and ω-rhamnoglutaric acid(rs=0.5387,P＜0.01),in feces were strongly positively correlated with body weight.Conclusions Cichorium glandulosum Boiss.et Huet.alcoholic extract may play a role in weight reduction and amelioration of dyslipidemia by modulating secondary bile acid biosynthesis and altering fecal bile acid metabolic profiles.

Hydration status refers to the balance between the intake and discharge of water in the body. When the ingested and discharged water are roughly equal and the body is in water balance, it is the normal hydration status, and when the water intake is too little or too much, it is the "dehydration" or "overhydration status". The hydration status of the body not only affects metabolism, but also affects the functions of the urinary system, cardiovascular system, nervous system, etc. In order to further clarify the relationship between body hydration status and decompression sickness (DCS), this paper reviewed relevant studies and analyzed the interaction between hydration and decompression safety during diving. The primary causes of dehydration in diving are "hyperbaric diuresis", "immersion diuresis", breathing dry gas, heat, and cold. Dehydration not only promotes the occurrence of DCS but also reduces the aerobic work efficiency and athletic performance of divers, as well as affects cognition and mood. A study found that appropriate rehydration before and during diving can reduce the risk of DCS, which possibly associates with the increase of blood volume, plasma surface tension, and vasoconstriction. Fluid therapy is also important for those who already have DCS. This paper analyzed the amount, nature, timing, and effect of rehydration involved in the above links, comprehensively sorted out the relationship between hydration and diving safety, summarized the existing problems, and provided reference for practical application and future research.
