Clinical characteristics and prognosis of 28 cases of infant acute lymphoblastic leukemia / 中华儿科杂志

Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

Role of Endoplasmic Reticulum Stress in Atherosclerosis and Its Regulation by Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.

The coronary heart disease of phlegm-stasis cementation syndrome in mini-swine based on platelet proteomics / 药学学报

Based on the technology of platelet proteomics, the key regulatory proteins and pathogenesis of coronary heart disease with phlegm and blood stasis syndrome were explored and analyzed. Based on the previous laboratory research, the model of coronary heart disease in mini-swine with phlegm-stasis cementation syndrome was duplicated. The model was judged by the changes in blood lipid and myocardial tissue characteristics. Furthermore, the platelet proteins were studied by quantitative proteomics, and the differentially expressed proteins were screened. The critical regulatory proteins and biological pathways of coronary heart disease with phlegm-stasis cementation syndrome were analyzed by bioinformatics. After ten weeks of modeling, the levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low density lipoprotein (VLDL-C), triglyceride (TG), creatine kinase (CK) and creatine kinase-MB (CK-MB) in the model group were significantly increased, reflecting the pathological changes such as increased blood lipid, abnormal coagulation function and myocardial ischemia in the model group. In addition, compared with the sham group, there were 26 up-regulated proteins and 8 down-regulated proteins in the platelets of the model group. Combined with bioinformatics analysis, it was found that differential proteins mainly involved in glycolysis/gluconeogenesis, pyruvate metabolism, lipid and atherosclerosis, Ras protein signal transduction. Among them, lactate dehydrogenase B (LDHB), alcohol dehydrogenase 5 (ADH5), neuroblastoma ratsarcoma viral oncogene homolog (NRAS) and Kirsten ratsarcoma viral oncogene homolog (KRAS) play a central role when interacting with other proteins and simultaneously participate in multiple action pathways. The results showed that LDHB, ADH5, NRAS, and KRAS may be the marker proteins in CHD with phlegm-stasis cementation syndrome by regulating glycolysis/gluconeogenesis, pyruvate metabolism, lipid and atherosclerosis, Ras protein signal transduction and other biological processes.

Early Enteral Nutrition and Sepsis-Associated Acute Kidney Injury: A Propensity Score Matched Cohort Study Based on the MIMIC-III Database

Purpose@#We aimed to analyze the optimal timing of enteral nutrition (EN) in the treatment of sepsis and its effect on sepsis-associated acute kidney injury (SA-AKI.) Materials and Methods: The MIMIC-III database was employed to identify patients with sepsis who had received EN. With AKI as the primary outcome variable, receiver operating characteristic (ROC) curves were utilized to calculate the optimal cut-off time of early EN (EEN). Propensity score matching (PSM) was employed to control confounding effects. Logistic regressions and propensity score-based inverse probability of treatment weighting were utilized to assess the robustness of our findings. Comparisons within the EEN group were performed. @*Results@#2364 patients were included in our study. With 53 hours after intensive care units (ICU) admission as the cut-off time of EEN according to the ROC curve, 1212 patients were assigned to the EEN group and the other 1152 to the delayed EN group. The risk of SA-AKI was reduced in the EEN group (odds ratio 0.319, 95% confidence interval 0.245–0.413, p<0.001). The EEN patients received fewer volumes (mL) of intravenous fluid (IVF) during their ICU stay (3750 mL vs. 5513.23 mL, p<0.001). The mediating effect of IVF was significant (p<0.001 for the average causal mediation effect). No significant differences were found within the EEN group (0–48 hours vs. 48–53 hours), except that patients initiating EN within 48 hours spent fewer days in ICU and hospital. @*Conclusion@#EEN is associated with decreased risk of SA-AKI, and this beneficial effect may be proportionally mediated by IVF volume.

Melanogenesis of quality markers in Vernonia anthelmintica Injection based on UPLC-Q-TOF-MS combined network pharmacology / 中国中药杂志

This study aimed to evaluate the biological effect and mechanism of Vernonia anthelmintica Injection(VAI) on melanin accumulation. The in vivo depigmentation model was induced by propylthiouracil(PTU) in zebrafish, and the effect of VAI on melanin accumulation was evaluated based on the in vitro B16F10 cell model. The chemical composition of VAI was identified according to the high-performance liquid chromatography quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS). Network pharmaco-logy was applied to predict potential targets and pathways of VAI. A "VAI component-target-pathway" network was established, and the pharmacodynamic molecules were screened out based on the topological characteristics of the network. The binding of active molecules to key targets was verified by molecular docking. The results showed that VAI promoted tyrosinase activity and melanin production in B16F10 cells in a dose-and time-dependent manner and could restore the melanin in the body of the zebrafish model. Fifty-six compounds were identified from VAI, including flavonoids(15/56), terpenoids(10/56), phenolic acids(9/56), fatty acids(9/56), steroids(6/56), and others(7/56). Network pharmacological analysis screened four potential quality markers, including apigenin, chrysoeriol, syringaresinol, and butein, involving 61 targets and 65 pathways, and molecular docking verified their binding to TYR, NFE2L2, CASP3, MAPK1, MAPK8, and MAPK14. It was found that the mRNA expression of MITF, TYR, TYRP1, and DCT in B16F10 cells was promoted. By UPLC-Q-TOF-MS and network pharmacology, this study determined the material basis of VAI against vitiligo, screened apigenin, chrysoeriol, syringaresinol, and butein as the quality markers of VAI, and verified the efficacy and internal mechanism of melanogenesis, providing a basis for quality control and further clinical research.

Quality of moxa with different leaf-to-moxa ratios based on correlation analysis of thermogravimetric properties, cellulose content, and microscopic characteristics of non-secretory trichomes / 中国中药杂志

The quality of moxa is a key factor affecting the efficacy of moxibustion. Traditional moxa grades are evaluated by the leaf-to-moxa ratio, but there is a lack of support from scientific data. Scanning electron microscopy(SEM), Image Pro Plus, Van Soest method, and stimultaneous thermal analysis(TGA/DSC) were used to characterize the scientific implication of the combustion differences between moxa with different leaf-to-moxa ratios(processed by crusher). The results showed that the median lengths from non-secretory trichomes(NSTs) of natural NSTs and moxa with leaf-to-moxa ratios of 3∶1, 5∶1, 10∶1, and 15∶1 were 542.46, 303.24, 291.18, 220.69, and 170.61 μm, respectively. The cellulose content of moxa increased significantly(P<0.05) with the increase in leaf-to-moxa ratio and the combustion parameters(T_i, t_i, D_i, C,-R_p,-R_v, S, D_b, and J_(total)) all showed an increasing trend. The correlation results showed that the burning properties of moxa(T_i,-R_v, t_i, and J_2) were significantly and positively correlated with cellulose content. NSTs with a length of 1-200 μm were significantly and positively correlated with J_2. NSTs with a length of 200-600 μm were significantly and positively correlated with J_1, T_(peak2), T_(peak1), and-R_v, and negatively correlated with J_(total), T_b, and t_b. As the leaf-to-moxa ratio increases, the NSTs in the moxa become shorter and the cellulose content increases, which is more conducive to ignition performance, heat release, and a milder, longer-lasting burn. The "NSTs-cellulose-TGA/DSC" quantitative evaluation method scientifically reveals the scientific connotation of the combustion of moxa with different leaf-to-moxa ratios and provides a scientific basis for the establishment of quality evaluation methods for moxa with different leaf-to-moxa ratios.

Cost-effectiveness analysis of nucleic acid screening for hepatitis B and C in hospitalized patients in China / 中华检验医学杂志

Objective:To compare the cost-effectiveness of hospitalized Chinese patients undergoing nucleic acid screening strategies for hepatitis B and hepatitis C, immunological screening strategy, and no screening strategy under different willingness to pay (WTP). The results might aid to decision-making for the optimal strategy.Methods:In this study, nucleic acid screening, immunological screening and no screening were used as screening strategies, and China′s GDP in 2021 (80 976 yuan) was used as the threshold of WTP to construct a Markov model. After introducing parameters related to the diagnosis and treatment of hepatitis B and C in inpatients, a cohort population of 100 000 inpatients was simulated by TreeAge Pro 2021 software, the total cost, total health effects, incremental cost-effectiveness ratio and average cost-effectiveness ratio of different screening strategies were calculated, and cost-effectiveness analysis was conducted. Univariate and probabilistic sensitivity analysis were used to assess the impact of parameter uncertainty on the final results.Results:Compared with the non-screening strategy, the incremental total cost of the hepatitis B immunological screening strategy for cohort patients was 11 049 536 yuan, and the incremental cost-effectiveness ratio was 24 762 yuan/quality-adjusted life years (QALY), while the total incremental cost of nucleic acid screening was 19 208 059 yuan, and the incremental cost-effectiveness ratio was 29 873 yuan/QALY; the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 834 yuan/QALY. Compared with the non-screening strategy, the incremental cost-effectiveness ratio of hepatitis C immunological screening strategy was 5 731 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening strategy was 8 722 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 591 yuan/QALY. The results of probabilistic sensitivity analysis showed that when the cost of nucleic acid testing exceeded 214.53 yuan, it was not cost-effective to perform hepatitis B nucleic acid screening under the WTP as 1 fold GDP. When the cost of nucleic acid testing exceeded 132.18 yuan, it was not cost-effective to conduct hepatitis C screening under the WTP as 1 fold GDP.Conclusions:Nucleic acid screening strategy can achieve more cost-effectiveness and is worthy of vigorous promotion. Compared with no screening, both the nucleic acid and immunological screening strategies are cost-effective, and hepatitis nucleic acid screening is the optimal strategy for hospitalized patients.

A multicenter study assessing the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease / 中华检验医学杂志

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.

Factors on malnutrition in patients with Alzheimer′s disease-related cognitive impairment: a preliminary analysis / 中华神经科杂志

Objective:To explore the factors on malnutrition or risk of malnutrition in patients with Alzheimer′s disease (AD)-related cognitive impairment,and to further analyze the association between the severity of behavioral and psychological symptoms in dementia (BPSD) and nutritional status.Methods:The clinical data of 247 patients with AD-related cognitive impairment were collected continuously from the Chinese Imaging, Biomarkers and Lifestyle Study of Alzheimer′s Disease (CIBL) cohort between June 1, 2021 and August 31, 2022. The patients were divided into well-nourished group ( n=128) and malnourished group ( n=119) according to the scores of Mini-Nutritional Assessment scale (MNA). The sociodemographic data (sex, age, body mass index, waist-to-hip ratio, education level), the medical history of olfactory dysfunction, combination with more than two chronic diseases, and gastrointestinal diseases, presenting BPSD, and the scores of the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Neuropsychiatric Inventory (NPI), Activity of Daily Living (ADL), Caregiver Burden Inventory (CBI) and Dietary Diversity Score (DDS) were compared between the two groups. The factors with statistically significant differences in hypothesis test and univariate Logistic regression analysis were enrolled in multivariate Logistic regression analysis to further identify independent factors associated with malnutrition in patients with AD-related cognitive impairment. Furthermore, the association between NPI scores and MNA scores was analyzed by Spearman′s rank correlation test. Results:Compared with those in the well-nourished group, patients in the malnourished group had higher age [(66.70±7.01) years vs (69.14±8.87) years, t=-2.39, P=0.018], lower body mass index [(24.68±2.84) kg/m 2vs (22.69±3.63) kg/m 2, t=4.78, P<0.001], and higher proportion of presenting BPSD [22.66% (29/128) vs 76.47% (91/119), χ 2=71.49, P<0.001]; lower scores of MMSE, MoCA, and DDS [24.27±4.69 vs 18.95±8.40, t=6.09; 20.29±5.18 vs 14.55±8.12, t=6.56; 8.00 (8.00, 9.00) vs 8.00 (7.00, 8.00), Z=-4.66; all P<0.001], and higher scores of NPI, ADL and CBI [1.00 (0, 6.00) vs 10.00 (2.00, 25.00), Z=-6.50; 20.00 (20.00, 22.00) vs 27.00 (20.00, 40.00), Z=-7.08; 1.00 (0, 14.75) vs 12.00 (2.00, 35.00), Z=-5.13; all P<0.001]. There were no statistically significant differences in the sex, waist-to-hip ratio, education level, and the medical history of olfactory dysfunction, combination with more than two chronic diseases, and gastrointestinal diseases between the two groups. The multiple Logistic regression analysis demonstrated that the decreased body mass index ( OR=0.79, 95% CI 0.70-0.89, P<0.001), presenting BPSD ( OR=7.84, 95% CI 3.67-16.73, P<0.001), elevated ADL scores ( OR=1.15, 95% CI 1.06-1.24, P<0.001) and CBI scores ( OR=0.98, 95% CI 0.97-1.00, P=0.026), and decreased scores of DDS ( OR=0.66, 95% CI 0.51-0.84, P=0.001) were independently associated with malnutrition in patients with AD-related cognitive impairment. The MNA scores were significantly negatively associated with NPI scores ( r=-0.483,95% CI -0.58--0.38, P<0.001). Conclusions:The decreased body mass index, dietary diversity, and ability of daily living, and presenting BPSD and heavy burden of caregivers can independently contribute to the malnutrition in patients with AD-related cognitive impairment. The more serious the BPSD, the worse the nutritional status.

Influencing factors of post stroke cognitive impairment in patients with acute ischemic stroke and their correlation with cognitive scores / 中华健康管理学杂志

Objective:To analyze the influencing factors of post stroke cognitive impairment (PSCI) and their correlation with cognitive scores in patients with acute ischemic stroke.Methods:In this cross-section study, 36 patients diagnosed with acute ischemic stroke and post stroke cognitive impairment (PSCI) admitted to the Department of Vascular Neurology of Beijing Tiantian Hospital Affiliated to Capital Medical University from June 1, 2022 to September 30, 2022 were selected as the PSCI group. And one to one matching was performed for patients without PSCI (PSNCI group) with an age±1 year and same gender admitted to the hospital during the same period (as control, 36 cases). Basic clinical data of the two groups were collected, the laboratory and imaging examinations were completed. Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) were used for cognitive evaluation by neuropsychologists. Hypothesis testing was used to compare the differences in basic data, laboratory tests and lesion sites between the two groups. Multi-factor conditional logistic regression was performed to analyze the influencing factors of PSCI, and Spearman correlation analysis was carried out to analyze the correlation between influencing factors of PSCI and the cognitive scores.Results:Compared with those in PSNCI group, the proportion of patients with stroke/transient ischemic attack history, hyperhomocysteinemia (HHcy), apolipoprotein E(ApoE) ε4 carriers and the ratio of temporal lobe and thalamus infarction were higher in PSCI group (41.7% vs 13.9%, 36.1% vs 2.8%, 30.6% vs 5.6%, 22.3% vs 2.8%, 25.0% vs 5.6%), the MMSE and MoCA scores were lower in PSCI group [16.50 (8.25, 19.00) vs 28.00 (27.00, 30.00), 10.00 (4.25, 14.50) vs 27.00 (25.00, 28.00)] (all P<0.05). Logistic regression analysis showed that HHcy was a positive correlation factor for PSCI ( OR=2.342, 95% CI=1.186-4.622, P=0.014). Spearman correlation analysis showed that MMSE ( r=-0.415) and MoCA ( r=-0.417) scores were negatively correlated with homocysteine (Hcy) (both P<0.05). Conclusion:HHcy is an important factor affecting the occurrence and development of PSCI in patients with acute ischemic stroke, and Hcy level is negatively correlated with cognitive scores in those patients.

Standard for monitoring and evaluation of two-dimensional- and three-dimensional-transesophageal echocardiography during transcatheter tricuspid valve replacement / 中华超声影像学杂志

Transcatheter tricuspid valve intervention is the new frontier of interventional cardiology. The LuX-Valve is a radial force-independent orthotopic tricuspid valve replacement device developed in China. The LuX-Valve Plus transcatheter tricuspid valve replacement (TTVR) system is changed from the trans-atrial to the transjugular approach, which further reduces trauma and pulmonary complications compared with the first generation LuX-Valve. The first-in-human study has been completed at Zhongshan Hospital, Fudan University and an exploratory multicentre clinical study is underway. Echocardiography plays an important role in pre-TTVR screening, intraoperative guidance and postoperative evaluation and follow-up, especially two-dimensional transoesophageal echocardiography (2D-TEE) and three-dimensional transoesophageal echocardiography (3D-TEE). However, there is a lack of appropriate intraoperative guidance and assessment protocols. In this study, we briefly described the protocols and imaging considerations for intraoperative 2D-TEE and 3D-TEE to ensure the successful implantation of TTVR.

Risk factors for postoperative recurrence of nonvalvular paroxysmal and persistent atrial fibrillation / 中国基层医药

Objective:To analyze the risk factors of postoperative recurrence of nonvalvular paroxysmal and persistent atrial fibrillation.Methods:A total of 100 patients who received treatment in Haining People's Hospital from October 2019 to October 2021 were included in this study. All patients were followed up for 1 year. Thirty patients with postoperative recurrence of atrial fibrillation were included in the observation group, and seventy patients without postoperative recurrence of atrial fibrillation were included in the control group. Univariate and multivariate logistic regression analyses were performed to analyze the risk factors of postoperative recurrence of atrial fibrillation after radiofrequency ablation.Results:Logistic regression analysis results revealed that age, body mass index, diabetes mellitus, hypertension, rheumatic heart disease, anteroposterior diameter of the left atrium, glycosylated hemoglobin, brain natriuretic peptide are the risk factors of recurrent atrial fibrillation after radiofrequency ablation (all P < 0.05) ( OR = 1.31, 1.33, 1.32, 1.34, 1.26, 1.24, 1.36, 1.33; 95% CI = 1.028-1.442, 1.031-1.427, 1.042-1.434, 1.124-1.452, 1.013-1.385, 1.005-1.326, 1.039-1.482, 1.064-1.478). Conclusion:The recurrence of nonvalvular paroxysmal and persistent atrial fibrillation after radiofrequency ablation is related to many factors. The risk factors should be taken into account in clinical practice, and targeted treatment should be given as early as possible to reduce the recurrence rate of atrial fibrillation and improve prognosis.

The results of meta-analysis showed that compared with the traditional care model, FICare model did not increase the risk of nosocomial infection ( RR=0.75, 95% CI 0.46-1.24, P=0.27) and unstable medical conditions ( RR=0.86, 95% CI 0.61-1.22, P=0.40). No significant difference existed in the all-cause mortality between FICare and traditional care ( RR=2.74, 95% CI 0.88-8.57, P=0.08). Conclusions:FICare does not increase the risk of nosocomial infection, unstable medical conditions and adverse events compared with traditional care. It is safe and feasible to implement FICare in NICU.

Developmental and epileptic encephalopathy with dyskinesia caused by the FRRS1L gene mutation: a case report and literature review / 中华实用儿科临床杂志

The clinical characteristics and gene mutation profiles of a child who was treated in Xuzhou Children′s Hospital, Xuzhou Medical University in June 2022 due to developmental and epileptic encephalopathy (DEE) combined with dyskinesia caused by the FRRS1L gene mutation was analyzed retrospectively.A male case 1 year and 9 months old presented developmental delay since childhood, hypotonia at the age of 6 months, treatment-resistant seizures (focal clonic seizures) at the age of 1 year and 7 months that were unable to be controlled by antiepileptic drugs, and developmental regression and abnormal movements of the hands and feet during the attack.Whole exome sequencing showed 2 heterozygous variants (missense mutation and deletion mutation) in the FRRS1L gene of the child.The missense mutation c. 754C>T (p.R252C) located in the 4 th exon was inherited from his mother, and the deletion mutation c. 438_c.459del (p.I146fs*4) located in the 2 th exon was inherited from his father, thus constituting a compound heterozygous mutation.Through literature review, all 6 relevant literatures involving 31 children with DEE were published in foreign countries.They presented similar clinical manifestations to this case, but the genotypes were different, all of which were homozygous mutations.The FRRS1L gene mutation can lead to DEE, which is characterized by the autosomal recessive inheritance pattern, refractory epilepsy onset in infancy, developmental regression and prominent dyskinetic movements with hyperkinesia, and poor long-term prognosis.

Diagnostic value of vaginal color Doppler flow parameters in different FIGO stages of epithelial ovarian cancer / 中华内分泌外科杂志

Objective:To investigate the diagnostic value of vaginal color Doppler flow parameters in patients with epithelial ovarian cancer in different FIGO staging.Methods:178 patients with ovarian tumors who were treated by surgery in Dingzhou People’s Hospital from Jul. 2016 to Jul. 2022 were selected, and they were divided into ovarian cancer group (65 cases) and ovarian cyst group (113 cases) according to the results of postoperative pathological diagnosis. According to FIGO staging standards, ovarian cancer was divided into FIGO stage I (18 cases) , FIGO stage II (16 cases) , FIGO stage III (16 cases) and FIGO stage IV (15 cases) . The blood flow parameters of vaginal color Doppler ultrasound were measured, including arterial pulsatility index (PI) , end diastolic flow velocity (EDV) , resistance index (RI) , peak flow velocity (PSV) , serum vascular endothelial growth factor (VEGF) and human epididymal epithelial secretory protein 4 (HE4) . The levels of PI, EDV, RI, PSV, VEGF and HE4 were compared between the two groups and patients with different FIGO stages, and the value of ROC analysis of vaginal color Doppler flow parameters in predicting the occurrence of ovarian cancer was analyzed. The correlation between FIGO stage and vaginal color Doppler flow parameters and serum VEGF and HE4 levels was analyzed by person coefficient.Results:PI and RI levels in ovarian cancer group were (0.79 ± 0.15) , and (0.39 ± 0.12) , lower than those in ovarian cyst group (1.51 ± 0.17) , (0.72 ± 0.16) ; EDV, PSV, HE4, VEGF levels were (13.88 ± 4.18) cm/s, (25.61 ± 4.53) cm/s, (283.92 ± 28.97) pmol/L, and (372.55 ± 38.96) ng/mL, higher than those in ovarian cyst group ( P<0.05) . According to ROC analysis, the best cutoff values of transvaginal color Doppler blood flow parameters for predicting the occurrence of ovarian cancer were PI<1.235, EDV≥10.985 cm/s, RI<0.580, PSV≥22.975cm/s, all P<0.05. The levels of PI and RI in patients with different FIGO stages showed a decreasing trend with the increase of the severity of the disease, while the levels of EDV, HE4 and VEGF showed an increasing trend ( P<0.05) . There was no significant difference in PSV levels between patients with different FIGO stages ( P>0.05) . The correlation analysis showed that FIGO stage was positively correlated with the blood flow parameters EDV and the levels of serum HE4 and VEGF. FIGO stage was negatively correlated with PI and RI ( P<0.05) . Conclusions:There were significant differences in the levels of PI, RI and EDV in patients with ovarian cysts and ovarian cancer at different FIGO stages. The levels of PI, RI and EDV are closely related to the malignant degree of ovarian cancer.

Current status of GSDME research in malignant tumors / 国际肿瘤学杂志

Pyroptosis is a type of programmed cell death distincted from apoptosis and necrosis, which is accompanied by the lysis of cell membranes and the release of cell contents. Pyroptosis occurs as mediated by Gasdermin protein family and is dependent on the activity of caspase. GSDME is one of the most important members of the Gasdermin protein superfamily. GSDME-mediated pyroptosis relies on the activity of caspase-3. In recent years, with further research on pyroptosis, the mechanism of GSDME-induced pyroptosis is becoming clear. Numerous studies have shown that GSDME-mediated pyroptosis plays an important role in the occurrence and development of tumors, as well as chemotherapy resistance. However, GSDME-mediated pyroptosis has no specificity and can induce pyroptosis of normal cells in the body while inducing tumor cell pyroptosis, thus causing different degrees of damage to various organs of the body. Further study on the mechanism of GSDME-induced pyroptosis, the role of GSDME in malignant tumors and the adverse reactions of chemotherapy can provide new ideas for tumor monitoring, treatment and prognosis judgment.
