Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

BACKGROUND: Biomarkers-based prediction of long-term risk of acute coronary syndrome (ACS) is scarce. We aim to develop a risk score integrating clinical routine information (C) and plasma biomarkers (B) for predicting long-term risk of ACS patients. METHODS: We included 2729 ACS patients from the OCEA (Observation of cardiovascular events in ACS patients). The earlier admitted 1910 patients were enrolled as development cohort; and the subsequently admitted 819 subjects were treated as validation cohort. We investigated 10-year risk of cardiovascular (CV) death, myocardial infarction (MI) and all cause death in these patients. Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was derived using main part of these variables. RESULTS: During 16,110 person-years of follow-up, there were 238 CV death/MI in the development cohort. The 7 most important predictors including in the final model were NT-proBNP, D-dimer, GDF-15, peripheral artery disease (PAD), Fibrinogen, ST-segment elevated MI (STEMI), left ventricular ejection fraction (LVEF), termed as CB-ACS score. C-index of the score for predication of cardiovascular events was 0.79 (95% CI: 0.76-0.82) in development cohort and 0.77 (95% CI: 0.76-0.78) in the validation cohort (5832 person-years of follow-up), which outperformed GRACE 2.0 and ABC-ACS risk score. The CB-ACS score was also well calibrated in development and validation cohort (Greenwood-Nam-D'Agostino: P = 0.70 and P = 0.07, respectively). CONCLUSIONS CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS. This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score.

Drug-induced liver injury(DILI)is a common adverse drug reaction in clinical practice,which can lead to acute liver failure and even death in severe cases.In recent years,with the continuous introduction of new drugs and the expansion of their usage,the incidence and mortality rates of DILI have shown an upward trend,posing significant challenges to public health and clinical treatment.Macrophages,as a crucial component of the innate immune system,exhibit high plasticity and heterogeneity.They can polarize into pro-inflammatory M1 type or anti-inflammatory M2 type in response to microenvironmental signals.Research has demonstrated that macrophage polarization plays a central regulatory role in the occurrence and progression of DILI by influencing various processes such as inflammatory responses,cell apoptosis,and tissue repair.This review focuses on elucidating the regulatory mechanisms and roles of macrophage polarization in DILI,providing a theoretical framework for developing precise immunotherapeutic strategies.

Objective To investigate the effect of dapagliflozin-mediated miR-98-5p on high glucose-induced damage in human renal tubular epithelial cells.Methods Blood samples from patients with diabetic nephropathy(DN)and healthy individuals were collected.The expression of serum miR-98-5p was detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR),and kidney injury-related indicators were measured using a biochemical immunoassay analyzer.HK-2 cells were cultured in vitro and randomly divided into control group(5 mmol·L-1 glucose),HG group(30 mmol·L-1 glucose),experimental-L group(30 mmol·L-1 glucose+20 μmol·L-1 dapagliflozin),experimental-H group(30 mmol·L-1 glucose+40 μmol·L-1 dapagliflozin),anti-miR-NC group(transfected with anti-miR-NC+30 mmol·L-1 glucose+40 μmol·L-1 dapagliflozin),and anti-miR-98-5p group(transfected with anti-miR-98-5p+30 mmol·L-1 glucose+40 μmol·L-1 dapagliflozin).Cell viability was evaluated using the cell counting kit 8(CCK-8)assay 24 hours after drug treatment;miR-98-5p expression in cells was detected by RT-qPCR;cell apoptosis rate was measured by flow cytometry,apoptosis-related protein expression was detected by Western blot;and inflammatory cytokine expression was measured by enzyme-linked immunosorbent assay.Results The expression levels of miR-98-5p in the serum of DN patients and healthy individuals were 1.00±0.25 and 0.39±0.05,respectively,showing a significant difference between the two groups(P＜0.05).The expression levels of miR-98-5p in the control group,HG group,experimental-H group,anti-miR-NC group,and anti-miR-98-5p group were 1.00±0.09,0.31±0.04,0.72±0.06,0.75±0.07 and 0.22±0.03;the cell survival rates were(100.00±3.36)％,(51.63±5.89)％,(79.46±9.90)％,(82.88±5.71)％and(59.69±7.43)％;apoptosis rates were(3.52±0.20)％,(35.80±3.67)％,(16.43±1.57)％,(15.71±1.42)％and(29.37±2.18)％;tumor necrosis factor-α(TNF-α)levels were(22.46±1.67),(68.37±6.05),(34.45±2.47),(35.11±2.84)and(60.46±3.56)pg·mL-1,respectively.The differences among these indicators were all statistically significant when comparing the HG group to the control group,the experimental-H group to the HG group,and the anti-miR-98-5p group to the anti-miR-NC group(all P＜0.05).Conclusion Dapagliflozin can alleviate high glucose-induced HK-2 cell damage by upregulating the expression of miR-98-5p,inhibiting inflammation,and reducing cell apoptosis.

Objective:To explore the effects of participatory interactive teaching in the clinical internship course of pediatric infectious diseases.Methods:217 undergraduate students of grade 2018 majoring in pediatrics were selected as the experimental group, and 208 undergraduate students of grade 2017 majoring in pediatrics were selected as the control group. The experimental group used the teaching method of BOPPPS combined with case-based learning and team-based learning, while the control group adopted the traditional teaching method. Evaluate the learning effectiveness by comparing the formative evaluation and theoretical exam scores of the two groups , and a questionnaire survey was conducted for the students in the experimental group to investigate teaching feedback. SPSS 19.0 was used to perform the t test for data analysis. Results:The experimental group had significantly better scores than the control group in final theoretical examination [(75.04±9.12) vs. (71.03±9.51), P<0.05] and formative evaluation [(81.03±6.13) vs. (70.02±10.32), P<0.05]. According to the results of the questionnaire survey on teaching satisfaction, the students were satisfied with the interactive participatory teaching method in the four aspects of improving learning interest, improving learning ability, classroom satisfaction level, and course acceptance level. Conclusions:The pragmatic teaching reform in the internship of pediatric infectious diseases is highly accepted by students and beneficial to improving students' clinical thinking ability and comprehensive quality, which is worth further application and promotion.

Objective To investigate the environmental contamination related to first patient with carbapenem-re-sistant Acinetobacter baumannii(CRAB)infection and the infection status of relevant patients in a newly established intensive care unit(ICU)of a hospital in Tibetan area,and analyze the transmission risk.Methods From the ad-mission in ICU of a patients who was first detected CRAB on November 15,2021 to the 60th day of hospitalization,all patients who stayed in ICU for＞48 hours were performed active screening on CRAB.On the 30th day and 60th day of the admission to the ICU of the first CRAB-infected patient,environment specimens were taken respectively 2 hours after high-frequency diagnostic and therapeutic activities but before disinfection,and after disinfection but before medical activities.CRAB was cultured with chromogenic culture medium.Results Among the 13 patients who were actively screened,1 case was CRAB positive,he was transferred from the ICU of a tertiary hospital to the ICU of this hospital on November 19th.On the 40th day of admission to the ICU,he had fever,increased frequency for sputum suction,and CRAB was detected.The drug sensitivity spectrum was similar to that of the first case,and he also stayed in the adjacent bed of the first case.64 environmental specimens were taken,and 9 were positive for CRAB,with a positive rate of 14.06％,8 sampling points such as the washbasin,door handle and bed rail were positive for CRAB after high-frequency diagnostic and therapeutic activities.After routine disinfection,CRAB was detected from the sink of the washbasin.Conclusion For the prevention and control of CRAB in the basic-level ICU in ethnic areas,it is feasible to conduct risk assessment on admitted patients and adopt bundled prevention and con-trol measures for high-risk patients upon admission.Attention should be paid to the contaminated areas(such as washbasin,door handle,and bed rail)as well as the effectiveness of disinfection of sink of washbasin.

Objective:To preliminarily investigate the clinical outcomes of secondary loop electrosurgical excision procedure (LEEP) combined with transcervical resection of endocervical tissue (i.e., second combined surgeries) in patients with positive endocervical margins following the initial LEEP for high-grade squamous intraepithelial lesion (HSIL) or adenocarcinoma in situ (AIS) of the cervix.Methods:Patients who underwent second combined surgeries due to positive endocervical margins after the initial LEEP for cervical HSIL or AIS at Obstetrics and Gynecology Hospital, Fudan University between August 2015 and September 2023 were included. Postoperative cytological examinations, high-risk human papillomavirus (HR-HPV) testing, colposcopic biopsy results, and cervical canal length were followed up to evaluate the clinical efficacy of second combined surgeries.Results:(1) General clinical data: a total of 67 patients were enrolled, including 34 with cervical HSIL (HSIL group) and 33 with AIS (AIS group). In the HSIL group before the time of initial LEEP, the mean age was (41.3±5.3) years, with all patients positive for HR-HPV preoperatively. Preoperative cytology results revealed ≤low-grade squamous intraepithelial lesion (LSIL) in 13 cases and ≥HSIL in 21 cases. The preoperative cervical canal length was (3.71±0.17) cm. Patients in the AIS group before their the first LEEP were at an average age of (39.1±8.7) years old, with preoperative HR-HPV positive. Among them, 16 cases showed preoperative cytological results of ≤LSIL, while 17 cases showed ≥HSIL. The preoperative cervical canal length was (3.64±0.21) cm. (2) Pathological findings and postoperative follow-up of the HSIL group following second combined surgeries:in the HSIL group, the residual rate of HSIL in the endocervical canal tissue (ECT) was 24% (8/34). Out of the 34 HSIL patients, 10 cases (29%, 10/34) remained with positive endocervical margins post-second combined surgeries. Among these 10 patients, 5 cases (5/10) had no lesion detected in ECT, while the remaining 5 cases (5/10) exhibited HSIL in their ECT. Conversely, 24 patients (71%, 24/34) had negative endocervical margins after second combined surgeries. Of these 24 patients, 3 cases (12%, 3/24) were found to have HSIL in ECT, and 21 cases (88%, 21/24) had no lesion in ECT. During follow-ups conducted at 6 and 12 months post-second combined surgeries, the clearance rates of HR-HPV were 91% (31/34) and 100% (34/34), respectively. Notably, among the 29 patients (85%, 29/34) who were followed up for a period of 2 years or longer, all cases maintained a consistently negative HR-HPV status, highlighting the effectiveness of second combined surgeries in achieving long-term HR-HPV clearance (100%, 29/29). (3) Pathological findings and postoperative follow-up of the AIS group following second combined surgeries: the residual rate of AIS in the ECT following second combined surgeries among AIS patients was 15% (5/33). Out of the 33 AIS patients, 11 cases (33%, 11/33) had positive endocervical margins post-operation, among whom AIS was detected in the ECT of 2 cases (2/11), while 1 case (1/11) was diagnosed with adenocarcinoma in the cervical canal tissue (subsequently underwent radical surgery and was excluded from this study). In contrast, 22 patients (67%, 22/33) had negative endocervical margins post-operation, with AIS found in the ECT of 2 cases (9%, 2/22) and no lesions detected in the remaining 20 cases (91%, 20/22). Follow-up evaluations conducted at 6 and 12 months postoperatively revealed HR-HPV clearance rates of 91% (29/32) and 97% (31/32), respectively. All 32 (100%, 32/32) AIS patients were followed up for a duration of ≥2 years post-second combined surgeries, during which HR-HPV remained consistently negative. (4) Complications and cervical length following second combined surgeries: neither the HSIL group nor the AIS group experienced significant complications such as hemorrhage, infection or cervical canal adhesion. At the 6-month follow-up, the cervical length of both HSIL and AIS patients exceeded 3 cm. By the 12-month follow-up, the cervical length had recovered to 96.5% and 97.5% when compared to the original length, respectively, for the HSIL and AIS groups.Conclusions:For patients with HSIL or AIS who exhibit positive endocervical margins following the initial LEEP procedure, undergoing second combined surgeries presents as an optimal choice. This surgical intervention guarantees thorough excision of the lesion, and subsequent colposcopic follow-up evaluations consistently demonstrate an absence of residual disease or recurrence. Moreover, it augments the rate of sustained HR-HPV negativity, thereby contributing to more favorable clinical outcomes.

Objective:To explore the value of CO 2 laser therapy, photodynamic therapy, and follow-up observation in the management of cervical low-grade squamous intraepithelial lesion (LSIL). Methods:Women diagnosed with cervical LSIL and high risk human papillomavirus (HR-HPV) infection through colposcopy-guided biopsy from January 1, 2021 to December 31, 2023 were collected. According to a 1∶1 ratio, 107 cases were included in each of the laser treatment, photodynamic therapy, and follow-up groups. The complete remission rate and HR-HPV clearance rate were compared during the 6-12 months follow-up period.Results:(1) Comparison of clinical data among the three groups before treatment: the median age of the 321 patients was (34.9±8.1) years. Before treatment, cytological abnormalities were present in 51.7% (166/321) of patients, and 35.2% (113/321) had human papillomavirus (HPV) 16/18 infections. The accuracy rate of colposcopic diagnosis was 69.2% (222/321). Age, cytology results, HPV 16/18 infection, and colposcopy diagnosis in the laser group, photodynamic group, and follow-up group were compared, and there were not statistically significant differences (all P>0.05). (2) During the 6-12 months follow-up period, the complete remission rate was 89.7% (96/107) in the laser group, slightly higher than the 86.9% (93/107) in the photodynamic group, with no statistical difference between the two groups ( χ2=0.41, P=0.523). However, both were significantly higher than the 64.5% (69/107) in the follow-up group ( χ2=19.30, P<0.001; χ2=14.63, P<0.001). The HR-HPV clearance rates in the laser and photodynamic groups were 73.8% (79/107) and 68.2% (73/107), respectively, both significantly higher than the 32.7% (35/107) in the follow-up group ( χ2=36.34, P<0.001; χ2=26.99, P<0.001), but with no statistical difference between the laser and photodynamic groups ( χ2=0.82, P=0.366). Conclusions:CO 2 laser therapy and photodynamic therapy are effective treatments for cervical LSIL, significantly superior to follow-up observation in terms of lesion remission and HR-HPV clearance rates. Individualized treatment plans could be developed based on the patient′s age, duration of HR-HPV infection, colposcopic impression, and economic conditions.
