Metabolic reprogramming， as one of the core hallmarks of malignant tumors， plays a key role in the occurrence， development and treatment of breast cancer （BC）. Abnormal changes in glucose metabolism， amino acid metabolism， lipid metabolism， as well as the tricarboxylic acid （TCA） cycle and oxidative phosphorylation （OXPHOS） pathways significantly influence the pathogenesis and progression of BC. Studies have shown that various active components of traditional Chinese medicine （TCM） （such as berberine， matrine， quercetin， curcumin， etc.） and their compound formulations （e.g. Xihuang pill， Danzhi xiaoyao powder， Yanghe decoction， etc.） can inhibit the proliferation and migration of BC cells and induce apoptosis by regulating key metabolic pathways such as glycolysis， lipid synthesis， and amino acid metabolism. TCM demonstrates multi-target and holistic regulatory advantages in intervening in BC metabolic reprogramming， showing significant potential in modulating key molecules like hypoxia inducible factor-1α， hexokinase-2， pyruvate kinase M2， lactate dehydrogenase A， glucose transporter-1， fatty acid synthase， and signaling pathways such as AKT/mTOR. However， current researches still focus predominantly on glucose metabolism， with insufficient mechanistic studies on lipid metabolism， amino acid metabolism， the TCA cycle， and OXPHOS. The precise targets， molecular mechanisms， and clinical translation value of these interventions require further validation and clarification through more high-quality experimental studies and clinical trials.

As the pace of society increases and lifestyles change， the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer， and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them， signal transducer and activator of transcription （STAT） proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information， which can regulate downstream cell proliferation， apoptosis， cell migration， invasion， angiogenic factors， etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine， "heat toxicity" in "cancer toxicity" corresponds to inflammation， which is closely related to tumor development. As a major link associated with the inflammatory response， the STAT family has a promising role in the development and treatment of a variety of tumors， but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer， and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins， but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer， this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years， aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

Objective To investigate the expression of zinc finger protein 382(ZNF382)in diffuse large B-cell lymphoma(DLBCL)tissue and its relationship with clinical pathological characteristics and prognosis of DLBCL patients.Methods A total of 57 DLBCL patients admitted to the Department of Hematology,Luoyang Central Hospital from January 2014 to December 2018 were selected as the research subjects.The biopsy pathological specimens and clinical data of DLBCL patients were collected;another 20 patients of reactive proliferative lymph node tissue preserved in the Department of Pathology,Luoyang Central Hospital were taken as the control group.The expression of ZNF382 in DLBCL tissue and reactive proliferative lymph node tissue was detected by En vision two-step method.The difference of ZNF382 expression was compared between DLBCL tissue and reactive proliferative lymph node tissue.The correlations of ZNF382 expression with the clinical features such as age,gender,primary tumor site,Ann Arbor stage,international prognostic index(IPI)score,Hans typing,B-symptoms,bone marrow infiltration,giant masses,Eastern Cooperative Oncology Group(ECOG)score,β2-microglobulin(β2-MG),serum lactate dehydrogenase(LDH),Ki67,and chemotherapy regimen of DLBCL patients were analyzed by univariate analysis;the survival curve was drawed by Kaplan Meier method,and the univariate and multivariate survival analysis were performed by log-rank tests and Cox proportional risk regression models.Results The expression level of ZNF382 in DLBCL tissue was significantly lower than that in reactive proliferative lymph node tissue(Z=-5.056,P＜0.01).The expression level of ZNF382 was correlated with IPI score,Ann Arbor stage,Hans typing,B-symptoms,bone marrow infiltration and giant masses of DLBCL patients(P＜0.05);the expression level of ZNF382 was not associated to gender,age,primary site,ECOG score,β2-MG,serum LDH,Ki67,and whether the chemotherapy regimen combined with rituximab or not of DLBCL patients(P＞0.05).Among the 57 DLBCL patients,the treatment was effective in 36 patients(63.20％)and ineffective in 21 patients(36.80％);the expression level of ZNF382 in tumor tissue of DLBCL patients with effective treatment was significantly higher than that of DLBCL patients with ineffective treatment(Z=-2.895,P＜0.05).The 2-year event free survival rate of DLBCL patients in the ZNF382 high expression group was significantly higher than that in the ZNF382 low expression group(x2=17.955,P＜0.001).The results of univariate survival analysis showed that female,primary lymph nodes,B-symptoms,bone marrow infiltration,giant masses,IPI score≥3,elevated β2-MG,Ki67＞70％,non-germinal center B-cell-like lymphoma,Ann Arbor stageⅢ-Ⅳ and low expression of ZNF382 were risk factors for poor prognosis in DLBCL patients(P＜0.05).The results of multivariate analysis showed that primary lymph nodes,Ann Arbor stage Ⅲ-Ⅳ and low expression of ZNF382 were independent influencing factors for poor prognosis in DLBCL patients(P＜0.05).Conclusion ZNF382 protein is low expressed in the tumor tissues of DLBCL patients,which is closely related to the occurrence,development and prognosis of DLBCL;and it can be used as an indicator for evaluating the prognosis of DLBCL.

The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic. Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022. Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020, BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood. In particular, severe/critical cases of COVID-19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment. Importantly, the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototype-inactivated vaccines, supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records. Furthermore, even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection, vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged ≽ 60 years old. Together, our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines.

Objective    To analyze the safety and efficacy of vacuum-assisted venous drainage (VAVD) in cardiac surgery under cardiopulmonary bypass (CPB). Methods    A total of 180 patients from 3 centers between November 17, 2017 and October 1, 2018 were enrolled and randomly assigned to a VAVD group and a gravity drainage (GD) group by 1∶1 ratio. During the open-heart surgery under CPB, the VAVD group completely relied on VAVD, and the GD group used conventional GD. The primary endpoint was arterial flow before CPB, 15 min after aortic cross-clamping and rewarming to 36 °C of nasopharyngeal temperature. The secondary endpoints included hematocrit, hemoglobin concentration, blood product transfusion, etc. The safety endpoint was free hemoglobin concentration, etc. Results    The full analysis set contained 175 patients, 87 in the VAVD group and 88 in the GD group. Patients in the VAVD group were aged 52.8±12.0 years, and males accounted for 55.2%; patients in the GD group were aged 51.4±12.1 years, and males accounted for 59.1%. The demographic characteristics between the two groups were not statistically different. Compared to the GD group, the VAVD group could provide comparable arterial flow in CPB [average of 3 time points, 2.37±0.22 L/(min·m2) vs. 2.41±0.25 L/(min·m2), P=0.271], while not elevating free hemoglobin concentration. Conclusion    VAVD can provide enough venous drainage, while not elevating free hemoglobin concentration or damaging blood.

Objective    To explore the safety and feasibility of the establishment method and management strategy of prolonged support model with veno-venous extracorporeal membrane oxygenation (V-V ECMO) under dual lumen cannula (DLC) in conscious sheep. Methods    Three adult male sheep were selected. An Avalon Elite DLC was inserted into the superior vena cava, right atrium, and inferior vena cava through the right jugular vein and was connected with centrifugal pump and oxygenator to establish the extracorporeal membrane oxygenation circuit. All the 3 sheep were transferred into the monitoring cage after operation and were ambulatory after anesthesia recovery. Hemodynamic parameters and extracorporeal membrane oxygenation performance were measured every day. Results    All three sheep survived to the end of the experiment (7 days). In the whole process of the experiment, the basic vital signs of the experimental sheep were stable, and no serious bleeding or thrombotic events occurred. During the experiment, hemoglobin concentration and platelet count were relatively stable, plasma free hemoglobin was maintained at a low level, extracorporeal membrane oxygenation flow rate was stable, and oxygenation performance of oxygenator was good. Conclusion    Prolonged V-V ECMO model in conscious sheep under DLC is feasible and stable.

Objective: To explore the association between middle school students health literacy and bully victimization and associated sex difference, and to provide guidance for bully prevention in adolescents. Methods: During November 2017 to January 2018, 18 900 junior and senior high school students were enrolled from Hefei of Anhui Province, Shenyang of Liaoning Province, Yangjiang of Guangdong Province and Chongqing by multistage cluster sampling. A self rated questionnaires were used to collect demographic information, health literacy, and bully victimization. Group differences by different characteristics and the association between health literacy and bully victimization were analyzed. Results: The detection rates of campus and cyber bullying victimization were 15.8% (2 992/18 900) and 9.1% (1 723/18 900). Boys, junior high school students, students with poor family financial status and few close friends had a detection rate of 28.0%, 18.8%, 23.3%, and 33.6% of school bullying, which are higher than those of the control group ( χ 2=225.64, 148.07, 141.13, 143.49, P <0.01); boys, students with poor household income and few close friends, the detection rates of cyber bullying were 10.9%, 14.4%, and 20.1%, respectively, are higher than the control group ( χ 2=62.96, 112.82, 88.49, P <0.01). Multivariate Logistic regression analysis indicated that students with low overall and dimensions scores of health literacy were more likely to suffer from campus and cyber bullying, except for the dimension of physical activity. In addition, at all levels of health literacy, males are more likely to be bullied than females ( P <0.05). Conclusion Health literacy of middle school students is related to bully victimization, which is sex specific. Intervention programs of bullying should focus on health literacy enhancement.

Objective: To explore the association between health literacy and drinking behaviors among middle school students in six provinces of China, and to provide scientific basis for the prevention and intervention of drinking behaviors. Methods: From November 2015 to January 2016, 22 628 students were enrolled from Ulanqab, Shenyang, Xinxiang, Bengbu, Chongqing and Yangjiang by multistage stratified cluster sampling method. And a questionnaire survey was conducted among them to collect demographic information, health literacy and drinking behaviors. Rates on drinking behaviors were compared in students with specific characteristics. Multiple Logistic regression analyses were conducted to examine the association between health literacy and drinking behaviors. Results: The proportion of ever drinking, current drinking, binge drinking, drunkenness was 60.0%(13 580), 16.8%(3 799), 5.9%(1 344) and 9.9%(2 250), respectively. After adjusting for gender, grade, family address, siblings, accommodation type, parental educational level, and self reported family income, compared to the high level health literacy, the low level health literacy was significantly associated with ever drinking (OR=1.76, 95%CI=1.62-1.91), current drinking(OR=1.37, 95%CI=1.23-1.52), binge drinking (OR=1.39, 95%CI=1.18-1.63), and drunkenness(OR=1.68, 95%CI=1.47-1.92), respectively(P<0.01). Conclusion Health literacy of middle school students was related to drinking behaviors. The occurrence of health risk behaviors such as drinking can be prevented and reduced by improving students health literacy level.

Objective:To investigate the effect of rapamycin (Rapa) on apoptosis of acute myeloid leukemia THP-1 cells induced by idarubicin (IDA) and its molecular mechanism.Methods:The THP-1 cells were treated with 10, 20, 40 and 80 nmol/L Rapa for 1 h, and the cells without Rapa treatment were set up. Western blot was used to detect the conversion of autophagy marker LC3 protein in THP-1 cells (the ratio of LC3Ⅱ/LC3Ⅰ), flow cytometry was used to detect the apoptotic rate, and the pretreatment concentration of Rapa was determined. THP-1 cells were treated with different concentrations of IDA for 24 h, the cell proliferation inhibition rate of IDA for THP-1 cells was detected by CCK-8 method, and the half maximal inhibitory concentration ( IC50) was calculated. THP-1 cells with or without Rapa treatment were treated by IDA with the concentration of lower than IC50 for 24 h, CCK-8 method was used to detect cell proliferation inhibition rate, flow cytometry was used to detect cell apoptosis, real-time fluorescent quantitative polymerase chain reaction was used to detect the expression changes of autophagy-related genes Beclin-1, LC3 and p62, and Western blot was used to detect the conversion of autophagy marker LC3 protein. Results:The ratio of LC3Ⅱ/LC3Ⅰ in THP-1 cells treated by 20 nmol/L Rapa was higher than that in the untreated cells ( P=0.002 4). The apoptotic rate in THP-1 cells treated by 80 nmol/L Rapa was higher than that in the untreated cells ( P=0.007 3). According to the results of Western blot and flow cytometry, 20 nmol/L Rapa was selected as the pretreatment concentration. The IC50 of IDA for THP-1 cells treated with IDA for 24 h was 59.874 nmol/L. After treated with 50 nmol/L IDA for 24 h, the proliferation inhibitory [(69.67±5.03)% vs. (41.67±3.51)%] and apoptotic rates [(74.35±4.83)% vs. (41.25±5.24)%] in THP-1 cells pretreated by Rapa were higher than those in the unpretreated cells (both P<0.05); the Beclin-1 and LC3 mRNA expression levels and the ratio of LC3Ⅱ/LC3Ⅰ in THP-1 cells pretreated by Rapa were higher than those in the unpretreated cells, and the expression of p62 mRNA was lower than that in the unpretreated cells (all P<0.05). Conclusion:Rapa can enhance the apoptosis of THP-1 cells induced by a relative low dose of IDA, which may be achieved through inducing excessive autophagy in THP-1 cells.

Informatization plays an important role in the management of clinical diagnosis and treatment. However, due to the specialty of the discipline, the informatization construction of critical care medicine(CCM)is faced with such problems as the inefficient application of data, the low compliance of diagnosis and treatment operation, and the lack of intelligent quality control tools. The authors discussed the new mode of CCM information management based on data driven. By upgrading clinical information system, establishing single disease control system, introducing comprehensive intelligent analysis platform and building open remote platform, the bottleneck of CCM informatization was broken. The information collection and interaction in ICU was realized, the automatic monitoring and early warning of diagnosis and treatment process was realized, the operation of medical staff according to the guidelines was effectively improved, and the ability of diagnosis and treatment and management efficiency was improved.Furthermore, the homogenization of regional critical medical information could be promoted.
