BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts. RESULTS AND CONCLUSION:The number of articles,citation frequency,institutions and personnel involved in the research about liver organoids showed an overall upward trend in the last 20 years,indicating that the field was growing rapidly and attention was increasing.The USA had published the most papers and had the strongest influence in this field.Although it had invested a lot of time and energy,the number of papers published by a single research institution in the USA was not the highest among many research institutions.China was second only to the USA in the number of publications,with the Chinese Academy of Sciences and Fudan University leading the list.Utrecht University in the Netherlands was the institution with the most publications.Clevers H was the author with the highest number of articles.The article with the highest co-citation frequency was"Long-term culture of genome-stable bipotent stem cells from adult human liver".The main fields of study for liver organoids were Molecular Science,Biology,and Immunology.The most frequently occurring keywords were stem cell,in vitro,and culture.The research hotspots in the liver organoids field were mainly focused on in vitro stem cell three-dimensional culture,differentiation and gene expression.

Objective:To systematically evaluate the clinical efficacy of compound α-ketoacid tablets in the treatment of diabetic kidney disease (DKD).Methods:CNKI, Wanfang database, EMBASE, PubMed and Cochrane Library database were searched for eligible records published from the establishment of individual database to November 13 th, 2022. The quality of the included studies were assessed, data were extracted, and meta-analysis was conducted using RevMan5.3. Results:A total of 26 randomized controlled trials were included, with a total of 2 790 DKD patients (1 465 in the experimental group and 1 325 in the control group). Multiple parameters were significantly improved in the experimental group compared with the control group, including 24-hour urinary protein, blood creatinine, urea nitrogen, nutritional index, oxidative stress level, fasting blood glucose, glycated hemoglobin, homocysteine, HGF, VEGF, TGF-β1, and systolic blood pressure.Conclusions:Limited low-quality evidence showed that compound α-ketoacid tablets combined with low-protein diet may be related to the improved 24-hour urinary protein, renal function, and glucose metabolism in patients with DKD. Due to the lack of randomized controlled trials designed for respective stages of DKD, the inclusion criteria of our study were relatively general, possibly leading to the lack of pertinence of the results. Some indicators showed apparent heterogeneity among different groups, and more high-quality multi-center studies with large sample sizes are still needed to verify our findings.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.

Objective: To explore the molecular biological mechanism of curcumol in regulating ferroptosis and autophagy. Methods: The Pharm Mapper database was used to screen out curcumol targets, various known related databases were used to establish a database of ferroptosis and autophagy related targets, and the String database was used to construct a protein-protein interaction network. The key targets were enriched and analyzed using DAVID database. Results: 152 curcumol targets, 259 ferroptosis targets, and 796 autophagy targets were obtained; curcumol mainly regulated the ferroptosis process through PTGS2, ALB, MAPK1, MAPK8, and MAPK14 targets, and curcumol mainly through HSP90 AA1, MAPK1, MAPK8, ALB, NOS3 targets regulated the autophagy process, and curcumol mainly regulated the ferroptosis and autophagy process through ALB, MAPK1, MAPK8 targets. Conclusion Curcumol can exert pharmacological effects by regulating ferroptosis and autophagy.

Objective:To explore the application effect of respiratory rehabilitation nursing led by respiratory rehabilitation nursing group in patients with acute exacerbation of chronic obstructive pulmonary disease.Methods:Using the convenient sampling method, a total of 124 patients with acute exacerbation of chronic obstructive pulmonary disease who were admitted to Department of Respiratory Medicine of China-Japan Friendship Hospital from June 2018 to June 2020 were selected as the research objects. Among them, 62 cases admitted to the hospital from June 2018 to June 2019 were set as the control group and 62 cases admitted to the hospital from July 2019 to June 2020 were set as the observation group. The control group was given routine nursing, while the observation group was given respiratory rehabilitation nursing by the respiratory rehabilitation nursing group. The differences in body mass index, airflow obstruction, dyspnea, and exercise capacity index (BODE) index, Chinese version of COPD Assessment Test (CAT) scale, activity of daily living (ADL) , self-efficacy and self-management ability were compared between the two groups before and after the intervention.Results:Finally, 58 patients in the control group and 61 patients in the observation group completed the study. After the intervention, the BODE index and CAT score of the observation group were lower than those before the intervention, and the scores of ADL, self-efficacy and self-management ability were increased, and they were all higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:In the respiratory rehabilitation nursing of patients with acute exacerbation of chronic obstructive pulmonary disease, a special respiratory rehabilitation nursing group can relieve the symptoms of dyspnea and improve the ADL, self-efficacy and self-management ability of patients, which is worthy of promotion.

Objective:To investigate the characteristics of fragility fractures of pelvis(FFP) in the elderly and compare the clinical efficacy between conservative treatment and minimally invasive surgery.Methods:A retrospective study was conducted in the 56 elderly FFP patients who had been treated at Department of Orthopaedics, The General Hospital of Chinese People＇s Liberation Army from January 2017 to January 2019. They were 16 males and 40 females, with an age of 73.4 years (from 65 to 93 years). By the American Society of Anesthesiologists (ASA) classification, there were 12 cases of grade Ⅰ, 16 cases of grade Ⅱ, 20 cases of grade Ⅲ, and 8 cases of grade Ⅳ; by the FFP classification, there were 6 cases of type Ⅰ, 10 cases of type Ⅱ, 36 cases of type Ⅲ, and 4 cases of type Ⅳ. The morphological characteristics and injury mechanisms of FFP were analyzed. According to the treatment methods, the patients were divided into a conservative treatment group of 32 cases and a minimally invasive surgery group of 24 cases. The 2 groups were compared in terms of complication incidence, mortality and the Koval attenuation rate of walking ability after one-year follow-up.Results:There were mostly the fractures of pubic branches on both sides of the pubic symphysis and compression fractures of the sacral wing caused by lateral crush injury. The 2 groups were comparable due to no significant differences in the preoperative general data between them other than FFP classification ( P>0.05). By one year after treatment, the conservative treatment group had a complication incidence of 34.4% (11/32), a mortality of 9.4% (3/32) and a Koval attenuation rate of walking ability of 13.8% (4/29) while the minimally invasive surgery group had a complication incidence of 20.8% (5/24), a mortality of 4.2% (1/24) and a Koval attenuation rate of walking ability of 8.7%(2/23), showing no significant difference between the 2 groups ( P>0.05). Conclusions:The injury mechanism of geriatric FFP is mostly lateral compression injury. The fracture sites are mostly located on both sides of the pubic symphysis, pubic branches and the sacral wing of anterior and posterior rings simultaneously. Although there may be no significant difference in complication incidence, mortality or Koval attenuation rate of walking ability between conservative treatment and minimally invasive surgery after one year, the minimally invasive surgery deals with more unstable fracture types.

Objective:To explore the effectiveness of application of the internet of things in respiratory rehabilitation nursing for patients with chronic obstructive pulmonary disease (COPD) .Methods:Using the convenient sampling method, a total of 96 patients who were admitted to the Department of Respiration and Critical Care Medicine in the Center of Respiratory Medicine of China-Japan Friendship Hospital from January to December 2019 were selected as research objects. Patients were selected according to their willingness to use the internet of things devices for respiratory rehabilitation. Voluntary users were included in the observation group, while unwilling users were included in the control group, with 48 cases in each group. The control group received routine respiratory rehabilitation nursing, while the observation group received the internet of things scheme on the basis of the control group. The maximum inspiratory pressure (MIP) , activity of daily living (ADL) , rehabilitation exercise compliance and satisfaction were compared between the two groups before and after the intervention.Results:There were significant differences in the MIP and ADL between the two groups before and after the intervention ( P< 0.01) . After the intervention, the MIP, ADL, rehabilitation exercise compliance and satisfaction of patients in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of the internet of things in respiratory rehabilitation nursing of COPD patients can improve the MIP, ADL, rehabilitation exercise compliance and satisfaction of patients, which is worthy of clinical application and promotion.

OBJECTIVE: To analyze the current status of diagnosis and management of acute appendicitis (AA) in China. METHODS: Questionnaire survey was used to retrospectively collect data of hospitalized patients with AA from 43 medical centers nationwide in 2017 (Sort by number of cases provided: Jinling Hospital of Medical School of Nanjing University, The First Affiliated Hospital of Xinjiang Medical University, Lu'an People's Hospital, Tengzhou Central People's Hospital, Dalian Central Hospital, The Affiliated Hospital of Xuzhou Medical University, Dongying People's Hospital, Jinjiang Hospital of Traditional Chinese Medicine, Huangshan Shoukang Hospital, Xuyi People's Hospital, Nanjing Jiangbei People's Hospital, Lanzhou 940th Hospital of PLA, Heze Municipal Hospital, The First College of Clinical Medical Science of China Three Gorges University, Affiliated Jiujiang Hospital of Nanchang University, The Second People's Hospital of Hefei, Affiliated Central Hospital of Shandong Zaozhuang Mining Group, The Third People's Hospital of Kunshan City, Xuzhou First People's Hospital, The 81st Group Army Hospital of PLA, Linyi Central Hospital, The General Hospital of Huainan Eastern Hospital Group, The 908th Hospital of PLA, Liyang People's Hospital, The 901th Hospital of Joint Logistic Support Force, The Third Affiliated Hospital of Chongqing Medical University, The Fourth Hospital of Jilin University, Harbin Acheng District People's Hospital, The First Affiliated Hospital of Zhengzhou University, Nanjing Luhe People's Hospital, Taixing Municipal People's Hospital, Baotou Central Hospital, The Affiliated Hospital of Nantong University, Linyi People's Hospital, The 72st Group Army Hospital of PLA, Zaozhuang Municipal Hospital, People's Hospital of Dayu County, Taixing City Hospital of Traditional Chinese Medicine, Suzhou Municipal Hospital, Beijing Guang'anmen Hospital, Langxi County Hospital of Traditional Chinese Medicine, Nanyang Central Hospital, The Affiliated People's Hospital of Inner Mongolia Medical University).The diagnosis and management of AA were analyzed through unified summary. Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Objective To assess the factors associated with the restoration of spontaneous circulation (ROSC) and 2-year survival prognosis in patients with cardiac arrest (CA) after acute myocardial infarction (AMI),and after ROSC,the effects of various factors on midian survival time and on 2-year survival.Methods In a registry study from January 2005 to January 2015,all consecutive AMI-induced CA patients treated with cardiopulmonary resuscitation (CPR) admitted to our hospital were enrolled.The survivors were followed-up for 2 years.Univariate analysis was applied to evaluate factors associated with rate of ROSC and 2-year survival.Multivariable logistic regression analysis was applied to evaluate statistically significant factors in the univariate analysis.Medians with inter-quartile ranges were used to describe 2-year survival time affected by various factors after ROSC.Kaplan-Meier survival curve analysis was used to evaluate the effect of factors on 2-year survival.Results A total of 254 cases with CA after AMI were enrolled,including 129 cases of ROSC and 71 cases of 2-year survival.Univariate analysis showed age ≥ 70 years,CA occurred during 22:00-8:00,the duration time ofCPR ≥ 15 min and adrenaline dosage ＞ 5 mg were unfavorable predictors of ROSC;while,left ventricular ejection fraction (LVEF) ≥ 40％ before CA,shockable rhythm and percutaneous coronary intervention (PCI) therapy were favorable predictors.Besides,age ≥ 70 years,intubation during CPR,adrenaline dosage ＞ 5 mg and cardiogenic shock were unfavorable predictors of 2-year survival;While,male,normal daily activity before CA and PCI treatment were favorable predictors.Multivariable analysis showed age,the duration of CPR,adrenaline dosage,LVEF before CA,the rhythm during CPR and PCI therapy were independent predictors of ROSC.Age and PCI therapy were independent predictors of 2-year survival.Among patients,the survival time was affected by various factors after ROSC,and the factors with minimum 25％ and small median value were associated with cardiac rupture,cancer,adrenaline dosage ＞ 5 mg and cardiogenic shock.The factor with maximum 25％ value was PCI treatment (216 days).Kaplan-Meier survival analysis suggested that age ≥ 70 years was an unfavorable factor of 2-years survival (Log-rank test,P=0.007);while,PCI treatment was a favorable factor (Log-rank test,P＜0.01).PCI-related prognosis analysis showed that the effectiveness of PCI was related to the timing of PCI,the number of infarctrelated artery and the difference in culprit lesion.Conclusions The age ≥ 70 years was disadvantageous to both ROSC and 2-year survival.PCI treatment was favorable to both ROSC and 2-year survival.
