Objective:To explore the mediating role of anxiety/depression emotions between sleep quality and cognitive function in adolescents with attention deficit hyperactivity disorder(ADHD).Methods:A cross-sectional study design was adopted, involving 204 ADHD adolescents aged 12-18 who were treated between January 2021 and November 2023.All participants were assessed using the Pittsburgh sleep quality index(PSQI)for sleep quality, the self-rating anxiety scale(SAS) and self-rating depression scale(SDS) for emotional states.Four cognitive information processing processes(planning, simultaneous processing, attention, and successive processing) were evaluated by the Das-Naglieri cognitive assessment system(DN: CAS). Data were statistically analyzed using SPSS 23.0 and Zstats software, including descriptive statistics, Spearman correlation analysis, and mediation effect analysis.Results:Among ADHD adolescents, girls exhibited significantly higher rates of sleep disturbance(71.59%(63/88) vs 43.97%(51/116), χ2=15.490, P<0.001)and depressive emotion(47.73%(42/88) vs 33.62%(39/116), χ2=4.159, P=0.041)compared to boys.High school students had a significantly higher rate of sleep disturbance than middle school students(64.84%(59/91) vs 48.67%(55/113), χ2=5.341, P=0.021). Spearman correlation analysis revealed that sleep quality(8.00(6.00, 11.00)) in ADHD adolescents was significantly and positively correlated with anxiety(38.00(32.00, 46.00); r=0.504, P<0.01) and depression(46.00(39.00, 54.00); r=0.427, P<0.01). And sleep quality, anxiety and depression were significantly and negatively correlated with the DN: CAS total score(109.5(91.25, 123.75); r=-0.158--0.237, P<0.05). Mediation analysis indicated that anxiety mediated the relationship between sleep quality and attention function(indirect effect β=-0.159, Bootstrap 95% CI=-0.287--0.046). Conclusion:ADHD adolescents exhibit complex interactions among sleep quality, emotion, and cognitive function, sleep quality indirectly affects attention function through anxiety.

Qingweisan is one of the classical prescriptions commonly used in the treatment of oral diseases. By means of Bibliometrics， the authors collected the ancient books on Qingweisan and sifted out 411 valid data， involving 116 classics of traditional Chinese medicine. The historical origin， drug composition， indications， principle of composition， dosage，and preparation of Qingweisan were statistically analyzed， and it was found that the prescription originated from the Treatise on Spleen and Stomach（《脾胃论》） by LI Dongyuan and is composed of Rehmanniae Radix， Angelica Sinensis， Cortex Moutan， Coptidis Rhizoma and Cimicifugae Rhizoma， with the functions of clearing stomach， purging fire， cooling blood and dispersing depression. And Qingweisan was mainly used to treat toothache， headache， and preference for cold and aversion to heat caused by "excessive heat in yang brightness meridian". There were 352 indications recorded， most of which followed LI Dongyuan's theory and the expanded indications reached 70 kinds. Specifically， toothache （132） was the most， accounting for 22.49% of the total indications， followed by headache （60， 10.22%）. In addition， Qingweisan was widely used in modern clinical practice for multiple system diseases， among which oral system （197） was dominant， accounting for 72.69%， followed by skin system （28， 10.33%） and digestive system （27， 9.96%）. Although the indications were wide， the pathogenesis always belonged to "upward attack of stomach fire". Through the excavation and statistical analysis of the ancient books on Qingweisan and its modern clinical application， the authors aimed to provide a more scientific reference for the research and application of classical famous prescriptions.

【Objective】 To investigate the main causes of blood donor deferral in domestic blood center. 【Methods】 The causes of donor deferral were classified into 12 categories as previous medical history, drug use, alcohol consumption, menstrual period, underweight, abnormal blood pressure, abnormal body temperature, abnormal hemoglobin (Hb), lipemic blood, positive hepatitis B surface antigen (HBsAg), elevated alanine aminotransferase (ALT) and others according to the comparison indicators of Asia-Pacific Blood Network (APBN) and the national standard Blood Donor Health Examination Requirements. The relevant data of the top 3 causes of donor deferral, voluntarily reported by the members of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions from 2014 to 2019, were collected and a histogram was generated. 【Results】 The median donor deferral rate of 20 domestic blood centers from 2014 to 2019 was 12.14%, with the lowest at 0.18% and highest at 32.32%, respectively. The top three causes for donor deferral were elevated ALT, abnormal Hb and abnormal blood pressure in year 2014, 2015, 2018 and 2019; elevated ALT, lipemic blood and abnormal blood pressure in 2016; elevated ALT, abnormal Hb, and lipemic blood in 2017. 【Conclusion】 The main causes of donor deferral were elevated ALT, abnormal Hb, abnormal blood pressure and lipemic blood.

Objective:To explore the clinical features of bloodstream infections (BSI) in children with acute myeloid leukemia (AML) during the first induction chemotherapy.Methods:The clinical data, pathogen of BSI, antibiotic susceptibility in vitro, complications and prognosis of 204 newly diagnosed AML children admitted to Blood Diseases Hospital, Chinese Academy of Medical Sciences from August 2009 to December 2015 were analyzed retrospectively. χ 2 test was used for the comparison between groups and Logistic regression was used for BSI risk factor analysis. Results:Among 204 patients, 116 were males and 88 were females. The age was 8 (ranged from 1 to 14) years. Among them, 170 patients received MAE chemotherapies (etoposide, mitoxantrone and cytarabine) and 25 received IAE chemotherapies (etoposide, idarubicin and cytarabine). The other 9 patients used granulocyte colony stimulating factor (G-CSF)-priming regimen (aclacinomycin or homoharringtonine, cytarabine and G-CSF) for induction treatments. A total of 28 patients experienced BSI and the incidence rate was 13.7% (28/204), 26 of them developed BSI once and 2 patients developed twice. Gram-positive bacteria were predominant pathogens accounting for 53.3% (16/30) while gram-negative bacteria accounting for 40.0% (12/30) and fungal accounted for 6.7% (2/30). The most common detected pathogens were Coagulase negative Staphylococcus (CoNS, 26.7% (8/30)), followed by Streptococcus spp. (13.3% (4/30)) and Escherichia coli (13.3% (4/30)). Among Gram-negative bacteria (GNB), 3 cases showed carbapenem resistance and 2 cases were Stenotrophomonas maltophilia. BSI-related mortality was 28.6% (8/28). Infections caused by drug-resistant GNB or fungi resulted in 6 fatal cases. The incidence rate of BSI in group with severe neutropenia was higher than in group without it (16.6% (25/151) vs. 5.7% (3/53), χ2=3.933, P=0.047). Multivariable analysis showed severe neutropenia at the onset of fever was independent risk factor of BSI ( OR=4.258,95% CI 1.097-16.524, P=0.036). Conclusions:During the first induction chemotherapy courses, Gram-positive bacteria cause most of the BSI. Drug-resistant bacteria related infection often result in fatal outcomes. Severe neutropenia is a significant risk factor.

HuR (human antigen R), an mRNA-binding protein responsible for poor prognosis in nearly all kinds of malignancies, is a potential anti-tumor target for drug development. While screening HuR inhibitors with a fluorescence polarization (FP) based high-throughput screening (HTS) system, the clinically used drug eltrombopag was identified. Activity of eltrombopag on molecular level was verified with FP, electrophoretic mobility shift assay (EMSA), simulation docking and surface plasmon resonance (SPR). Further, we showed that eltrombopag inhibited cell proliferation of multiple cancer cell lines and macrophages, and the anti-tumor activity was also demonstrated in a 4T1 tumor-bearing mouse model. The data showed that eltrombopag was efficient in reducing microvessels in tumor tissues. We then confirmed the HuR-dependent anti-angiogenesis effect of eltrombopag in 4T1 cells and RAW264.7 macrophages with qRT-PCR, HuR-overexpression and HuR-silencing assays, RNA stability assays, RNA immunoprecipitation and luciferase assays. Finally, we analyzed the anti-angiogenesis effect of eltrombopag on human umbilical vein endothelial cells (HUVECs) mediated by macrophages with cell scratch assay and Matrigel angiogenesis assay. With these data, we revealed the HuR-dependent anti-angiogenesis effect of eltrombopag in breast tumor, suggesting that the existing drug eltrombopag may be used as an anti-cancer drug.

Objective:To study the factors related to infection by multiple drug-resistant bacteria (MDROs) in patients with infectious pancreatic necrosis (IPN).Methods:A retrospective study was conducted on the clinical data of 134 IPN patients with definitive etiologies treated in the Department of General Surgery, the Third Affiliated Hospital of Guizhou Medical University from January 2009 to February 2020. There were 85 males and 49 females. The age was (46.69±14.11) years. The IPN patients were divided into the multiple and the non-multiple MDROs infection groups based on drug resistance of pathogens in drainage fluid. The difference between the two groups of patients, including the number of antibacterial drugs used, the number of combined antibacterial drugs, the length of ICU stay, and other related factors were analyzed. Univariate and multivariate analyses were performed.Results:Among the 134 patients with IPN, 41 (30.60%) had complex MDROs infection and 93 (69.40%) had non complex MDROs infection. Univariate analysis showed that the course of disease, APACHE II score, extrapancreatic infection, number of surgical operations, time from onset to operation, patency of drainage tube, length of ICU stay, time of using antibiotics, number of changing courses of antibiotics, number of combined antibiotics, blood glucose and glycosylated hemoglobin were related to occurrence of multiple MDROs (all P<0.05); Multivariate analysis showed that glycated hemoglobin ( OR=3.957, 95% CI: 1.073-14.600), time from onset to operation ( OR=6.086, 95% CI: 1.263-29.325), number of changing courses of antibiotics ( OR=3.560, 95% CI: 1.077-11.772), number of combined antibiotics ( OR=3.560, 95% CI: 1.077-11.772), length of ICU stay ( OR=3.590, 95% CI: 1.126-11.448) were independent risk factors of MDROs infection in IPN patients ( P<0.05). Conclusion:Early debridement of infective foci, good control of blood glucose, reduced length of ICU stay, rational use of antibiotics to avoid unnecessary changing courses of antibiotics, appropriate use of combination of antibiotics could reduce the number of MDROs infection in IPN patients.

An 87-year-old female patient with hypertension was given 3 Suhuang Zhike capsules (0.45 g/capsule) for cough. Half an hour after medication, the patient suddenly developed limbs tremor, accompanied by palpitation and sweating. The symptoms lasted for about 10 minutes and relieved spontaneously. Her blood pressure was 145/79 mmHg. Her nervous system examination showed no abnormality; blood glucose, electrolyte, thyroid function, and liver and kidney function were all normal; and electroencephalogram and cranial computed tomography showed no obvious abnormality. Ephedrine in Suhuang Zhike capsules was considered to be related to her symptoms. The drug was stopped and oral alprazolam 0.4 mg was given twice daily. The symptoms of limbs tremor did not recur in the patient.
