Analysis of Depression and Influencing Factors in HIV/AIDS Patients Receiving Antiviral Therapy / 中山大学学报(医学科学版)

ObjectiveTo investigate the depression status and its influencing factors in HIV/AIDS patients receiving antiviral therapy. MethodsFrom July 2022 to September 2022， successive sampling method was used to recruit HIV/AIDS patients receiving antiviral therapy from antiviral treatment institutions in Nanjing， and they were instructed to fill out anonymous questionnaires. The questionnaire collected the basic information of patients， and depression， HIV stigma score and social support level were investigated by Patient Health Questionnaire-9 （PHQ-9）， Berger HIV stigma scale （BHSS） and Multidimensional Scale of Perceived Social Support （MSPSS）. Multivariate Logistic regression was used to analyze the influencing factors of depression. ResultsA total of 1879 valid questionnaires were collected in this study， and the detection rate of depression was 50.1%. The results of multivariate logistic analysis showed that compared with patients with middle school or below， the risk of depression was lower for those with postgraduate or above ［OR=0.534， 95%CI （0.341， 0.835）， P=0.006］. Compared with antiviral therapy duration<1 year， antiviral therapy duration for 1 to 5 years ［OR=0.729， 95%CI （0.536， 0.991）］， >5 to 10 years ［OR=0.516， 95%CI （0.379， 0.702）］， >10 years ［OR=0.603， 95%CI （0.375， 0.969）］ was associated with a lower risk of depression. High level of social support was a protective factor for depression in HIV/AIDS patients compared with middle and low level of social support ［OR=0.430， 95% CI（0.349， 0.530）， P < 0.001］. There was a higher risk of depression with side effects than without side effects ［OR=2.260， 95%CI （1.833， 2.786）， P < 0.001］. The higher the score on the HIV stigma scale， the higher the possibility of depression was. ConclusionThe detection rate of depression of patients receiving antiviral therapy in Nanjing is high. After starting antiviral therapy， we should strengthen the monitoring of side effects and psychological status of patients， carry out psychological intervention， alleviate psychological problems， and improve the quality of life of patients receiving antiviral therapy.

Rational analysis of the use of antiemetic drugs in tumor chemotherapy patients in our hospital / 中国药房

OBJECTIVE To provide reference for the rational use of antiemetic drugs in tumor chemotherapy patients. METHODS The data of tumor patients who were given antiemetic drugs were collected from 9 departments of our hospital with hospital information system from Oct. 1st to Nov. 30th in 2022， such as oncology department， radiotherapy department， gynecology department， and gastroenterology department. The application of chemotherapy drugs and the use of antiemetic drugs were analyzed statistically， and the irrational use of antiemetic drugs was analyzed. RESULTS A total of 520 patients were included， involving 248 （47.69%） using chemotherapy drugs with a moderate emetogenic risk level and 135 （25.96%） with a high emetogenic risk level. A total of 461 cases （73.06%） of 5-hydroxytryptamine 3-receptor antagonists were used， including palonosetron in 333 cases， ondansetron in 106 cases， tropisetron in 15 cases and granisetron in 7 cases， and only 148 cases of patients were prioritized for the use of nationally procured medicines and national essential medicines （32.10%）. Neurokinin-1 receptor antagonists were used in 170 cases （26.94%）， including fosaprepitant in 112 cases and aprepitant in 58 cases. The use of antiemetic drugs was unreasonable in 162 patients （31.15%）； among the types of irrational drugs， the antiemetic regimen was unreasonable in the largest number of cases （22.40%）， followed by the irrational pharmacoeconomics （19.13%）. CONCLUSIONS The emetogenic risk levels of chemotherapy drugs used for tumor patients in our hospital are primarily moderate to high， and there is irrational use of antiemetic regimen and pharmacoeconomics. Clinicians， nurses， pharmacists and hospital departments should collaborate as multiple teams to strengthen full supervision of the standardization of antiemetic drugs， reasonably select antiemetic drugs based on emetogenicity rating， and improve the compliance of doctors with the guidelines to ensure the safety， effectiveness， and cost-effective of patient medication.

Study of adverse drug events related to tacrolimus in pediatric solid organ transplant recipients based on FAERS database / 器官移植

Objective To investigate the characteristics of adverse drug event (ADE) related to tacrolimus (Tac) in pediatric solid organ transplant recipients. Methods The data were retrieved from the US Food and Drug Administration Adverse Event Reporting System database from the first quarter of 2004 to the second quarter of 2023. The ADE data of pediatric organ transplant recipients with Tac as the primary suspected drug were extracted. The relationship between Tac and ADE was quantitatively analyzed by proportional imbalance method. Basic characteristics and signal strength of ADE related to Tac were analyzed. ADE related to Tac in children of different ages and different types of organ transplantation were analyzed. Results A total of 1 443 children's ADE reports involving Tac were screened, including 188 cases (13.0%) of heart transplantation, 668 cases (46.3%) of liver transplantation, 531 cases (36.8%) of kidney transplantation and 56 cases (3.9%) of lung transplantation. The median age of children was 10 years old. The top three countries with ADE reporting were the United States, France and the United Kingdom. China reported 26 cases, accounting for 1.8%. Infection and infectious diseases accounted for the highest proportion (20.96%) in ADE related to Tac, including EB virus and cytomegalovirus infection, etc. Infection and infectious diseases occupied the largest proportion of ADE related to Tac in children of different ages, whereas the pathogen types were different. Rejection, unstable immunosuppression level and renal function damage were also common ADE related to Tac in children of all ages. Nervous system disease was the main ADE in heart transplant recipients, while infection and infectious diseases were more common in liver and kidney transplant recipients. Rejection was the most common ADE in lung transplant recipients. Conclusions ADE related to Tac possess different distribution characteristics in different types of organ transplantation. Extensive attention should be paid to individualized drug monitoring and risk assessment in pediatric organ transplant recipients, thereby optimizing Tac treatment and reducing the risk of ADE.

Building an improved transcription factor-centered yeast one hybrid system to identify DNA motifs bound by protein comprehensively.

BACKGROUND: Identification of the motifs bound by a transcription factor (TF) is important to reveal the function of TF. Previously, we built a transcription factor centered yeast one hybrid (TF-Centered Y1H) that could identify the motifs bound by a target TF. However, that method was difficult to comprehensively identify all the motifs bound by a TF. RESULTS: Here, we build an improved TF-Centered Y1H to comprehensively determine the motifs bound by a target TF. Recombination-mediated cloning in yeast was performed to construct a saturated prey library that contains 7 random base insertions. After TF-Centered Y1H screening, all the positive clones were pooled together to isolate pHIS2 vector. The insertion regions of pHIS2 were PCR amplified and the PCR product was subjected to high-throughput sequencing. The insertion sequences were then retrieved and analyzed using MEME program to identify the potential motifs bound by the TF. Using this technology, we studied the motifs bound by an ethylene-responsive factor (BpERF2) from birch. In total, 22 conserved motifs were identified, and most of them are novel cis-acting elements. Both the yeast one hybrid and electrophoretic mobility shift assay verified that the obtained motifs could be bound by BpERF2. In addition, chromatin immunoprecipitation (ChIP) study further suggested that the identified motifs can be bound by BpERF2 in cells of birch. These results together suggested that this technology is reliable and has biological significance. CONCLUSION: This method will have wide application in DNA-protein interaction studies.

Effects of ferrocene position isomerization on the self-assembly behavior and antibacterial effect of coupled cationic peptides / 中国药房

OBJECTIVE To design the two isomers of ferrocene （Fc）-coupled cationic peptides （hereinafter referred to as “peptides”） [Fc-K（C8）FFHK and C8-K（Fc） FFHK] and the control peptide [C8-K（C8）FFHK]， and to explore the effects of Fc position isomerization on the self-assembly behavior and antibacterial effect of peptides. METHODS All isomerized peptides were prepared by standard solid-phase synthesis and purified by reversed-phase high-performance liquid chromatography. The stability of the peptide was analyzed by using UV spectrophotometry to detect UV absorption spectra， and Zeta potential analyzer to determine Zeta potential. The secondary structure was characterized by circular dichroism spectrum （CD）， Fourier transform infrared spectrometer （FTIR）， thioflavin T （ThT） fluorescence spectrum and transmission electron microscopy （TEM）. The differences in antibacterial activity and biocompatibility of the 2 kinds of isomerized peptides were evaluated by in vitro reactive oxygen species （ROS） generation test， growth curve determination test， plate method， cytotoxicity assay and hemolysis test. RESULTS Three peptides with purity higher than 95% were synthesized. The stability test results showed that the UV absorption spectra of Fc-K（C8）FFHK and C8-K（Fc）FFHK remained almost unchanged when placed at room temperature for 24 and 96 hours， and their Zeta potential were decreased by 0.3 mV and 0.5 mV， respectively. Secondary structure characterization results showed that Fc-K（C8）FFHK and C8-K（Fc）FFHK were self-assembled to form twisted nanoribbons and short nanofibers， respectively； C8-K（C8）FFHK was assembled into cylindrical nanofibers. The optical spectrum results showed that there were certain differences in the content of structures such as β-sheet and α-helix. The in vitro ROS generation test results showed that ROS generation efficiency of Fc-K（C8）FFHK at pH 6.0 was higher than C8-K（Fc）FFHK. The results of in vitro antibacterial activity showed that for methicillin-resistant Staphylococcus aureus， both the isomeric peptides had similar minimum inhibitory concentration （MIC） values of 50 μg/mL which were far lower than the control peptide （400 μg/mL）. To Escherichia coli， Fc-K（C8）FFHK had better antibacterial activity than C8-K（Fc）FFHK. Finally， cytotoxicity assay and hemolysis test results showed that both isomeric peptides had good biocompatibility. CONCLUSIONS By wangjingwen8021@163.com coupling Fc， the antibacterial activity of cationic self-assembled peptides can be improved. Regulating the position of Fc in the peptide sequence could regulate the self-assembly behavior and antibacterial effect of the self-assembled peptides.

Objective:To investigate the role of heparin-binding protein (HBP) as a predictor of early bacterial infections in patients with traumatic intracerebral hemorrhage.Methods:Patients with traumatic intracerebral hemorrhage admitted to the Emergency Department of the First Hospital of Shanxi Medical University from September 2021 to June 2022 were collected prospectively. Patients with bacterial infection diagnosed by pathogenic examination were classified as the infected group, and those with negative pathogenic examination were classified as the non-infected group. Peripheral blood HBP counts were measured within 48 h of admission, and general information and relevant laboratory tests were collected. The differences of the indicators between the two groups were compared, the receiver operating characteristic (ROC) curve was drawn, the predictive value of the indicators for patients with co-infection was assessed, and the valuable predictors were screened out using multivariate logistic regression analysis.Results:Eighty-five patients [44 males and 41 females, aged (55.09±1.18) years] , were included in the study. Among the patients included in the study, 39 patients had bacterial infection and 46 were non-infected. Patients in the infected group were older , and had more surgeries, higher respiratory rate and injury severity score, and higher levels of HBP [(33.00±3.49) ng/mL vs. (16.27±1.61) ng/mL, P<0.001], leukocytes, and neutrophils [(15.32±3.19) ×10 9/L vs. (6.69±0.57) ×10 9/L, P=0.005] than in the non-infected group, while the Glasgow Coma Scale [(8.72±0.63) vs. (11.37±0.48), P=0.001] was lower than that in the non-infected group, with statistically significant differences (all P<0.05). There was no significant differences in lymphocytes, red blood cells, platelets, calcium, procalcitonin and coagulation indexes between the two groups (all P>0.05). Logistic regression analysis showed that neutrophils ( OR=1.252, 95% CI: 1.075-1.457, P=0.004) and HBP ( OR=1.081, 95% CI: 1.025-1.141, P=0.004) were independent risk factors for infection in patients with traumatic cerebral hemorrhage. The area under ROC curve for HBP of diagnosing early co-infection in patients with traumatic intracerebral hemorrhage was 0.82 (95% CI: 0.71-0.88), the sensitivity was 92.31%, and the specificity was 52.17%. Conclusions:HBP is a valuable predictor of early traumatic intracerebral hemorrhage complicated with bacterial infection in the emergency department, and has a good supplementary value to the existing test indicators.

ObjectiveTo evaluate the efficacy and influencing factors of Biejiajianwan in the treatment of primary liver cancer based on real-world data of traditional Chinese medicine （TCM）. MethodClinical diagnosis and treatment data of patients with primary liver cancer admitted to five Grade-A tertiary hospitals in Henan Province from January 2015 to December 2020 were collected from the medical electronic database. The patients treated with Biejiajianwan for ≥30 days were assigned to the exposure group and those without treatment with Biejiajianwan or treated with Biejiajianwan for <30 days to the non-exposure group. The propensity score matching model was used to balance confounding factors between the two groups according to the 1∶1 genetic matching method. Kaplan-Meier method was used for survival analysis and survival curve plotting. Log-rank was used to test the difference in survival rate between the two groups. Univariate analysis of Biejiajianwan in the treatment of primary liver cancer was performed by Log-rank test combined with the Kaplan-Meier method. The factors with statistical significance （P<0.05） were combined with unbalanced factors by the propensity score matching model， and at the same time， clinical common sense and relevant prognostic factors by literature search were considered， which were subjected to multivariate analysis by Cox proportional hazards regression model. ResultA total of 2 207 electronic cases were collected，including 174 cases in the exposure group （Biejiajianwan group） and 2 033 cases in the non-exposure group. After propensity score matching， there were 174 cases in the exposure group and 174 cases in the non-exposure group. The Kaplan-Meier method was used for survival analysis on the matched data， and the Log-rank test results showed that the survival rate of patients with primary liver cancer in the Biejiajianwan group was higher than that in the control group （χ2=12.193， P<0.01）. Cox proportional hazards regression model analysis showed that the regression coefficient of Biejiajianwan was -0.916 4 with the hazard ratio （HR） ［95% confidence interval （CI）］=0.4 （0.239 5-0.668 0）， P<0.01， and the regression coefficient of radiofrequency ablation treatment was -0.976 5 with HR （95% CI）=0.376 6 （0.172 8-0.821 1， P<0.05）. Fibrinogen （FIB） abnormal regression coefficient was 0.481 4 with HR （95% CI）=1.618 4（1.022 0-2.562 9），P<0.05. ConclusionBiejiajianwan can prolong the survival period of patients with primary liver cancer. Radiofrequency ablation is an independent protective factor for Biejiajianwan in the treatment of primary liver cancer，while abnormal FIB are independent risk factors for Biejiajianwan in the treatment of primary liver cancer.

Study on protective mechanism of kaempferol against cerebral ischemia/reperfusion injury in vitro and in vivo / 中国药房

OBJECTIVE To explore the protective mechanism of kaempferol （KAE）on cerebral ischemia/reperfusion （CI/R） injury in vitro and in vivo . METHODS Firstly，the potential targets of KAE in the treatment of CI/R injury were preliminarily screened by network pharmacology. AutoDock Vina software was used to conduct molecular docking between KAE and the top 10 core targets ，and the binding affinity was used as the evaluation standard to further clarify the possible mechanism of KAE in treating CI/R injury. Finally ，the above results were verified by in vivo and in vitro experiments. The oxygen glucose deprivation/ reperfusion（OGD/R）HT22 cell injury model and the middle cerebral artery occlusion （MCAO）rat model were constructed. The cell activity was detected by CCK- 8 method. The neural function score and TTC staining were performed on the rats and their brain tissues. The phosphorylation levels of protein kinase B （Akt）and Src in HT 22 cells and brain tissue of rats were detected by Western blot. RESULTS The results of network pharmacology screening showed that KAE in the treatment of CI/R injury was closely related to 10 core targets including prostaglandin-endoperoxide synthase 2，matrix metalloproteinase 9，JUN，Akt1，tumor necrosis factor ，caspase-3，mitogen activated protein kinase 8，intercellular cell adhesion molecule 1，vascular cell adhesion molecule 1 and Src. The results of molecular docking showed that KAE was stably bound with Akt 1 and Src . The results of in vitro and in vivo experiments showed that KAE could significantly improve the survival rate of OGD/R-injuried HT 22 cells （P＜0.05）， significantly reduced the neurological function score of MCAO model rats （P＜0.05），significantly reduces the volume of cerebral infarction in rats （P＜0.05），and significantly increased the phosphorylation levels of Akt and Src in HT 22 cells and brain tissue of rats（P＜0.05），which showed a dose dependent trend. CONCLUSIONS KAE may play a neuroprotective role by regulating the phosphorylation expression of Akt and Src ，thus treating CI/R injury.

The 35.4% (28/79) of children were complicated with multiple infections. There were 102 cases in improvement group; and there were 36 cases in deterioration group, among whom 5 cases died in hospital and 31 cases was discharged without treatment. The proportion of the girls in deterioration group was significantly higher than that in improvement group: 63.9% (23/36) vs. 34.3% (35/102), and there was statistical difference ( P<0.01); there were no statistical differences in age, infection site, mechanical ventilation, blood purification and PCIS between 2 groups ( P>0.05). The hs-cTnT and lactate in deterioration group were significantly higher than those in improvement group: (1.87 ± 0.67) ng/L vs. (1.62 ± 0.51) ng/L and (0.46 ± 0.31) ng/L vs. (0.34 ± 0.27) ng/L, and there were statistical differences ( P<0.05); there were no statistical differences in CK, CK-MB, myoglobin, PCT, LVEF, cardiac output and LVFS between 2 groups ( P>0.05). ROC curve analysis result showed that the hs-cTnT and lactate were risk factors for predicting clinical prognosis in children with sepsis complicated with myocardial injury, the area under the curve were 0.623 and 0.613, the optimal value were 159.59 and 2.65 ng/L, with a sensitivity of 36.1% and 55.6%, and a specificity of 98.2% and 70.6%. Multivariate Logistic regression analysis result showed that the hs-cTnT and gender were independent risk factors for prognosis ( OR = 2.237 and 0.286, 95% CI 1.093 to 4.578 and 0.127 to 0.644, P = 0.028 and 0.003). Conclusions:The 28 d mortality in children with sepsis complicated with myocardial injury is higher, and the respiratory tract is the most common infection site. The increased hs-cTnT and lactate levels indicate that the prognosis is poor in children with sepsis complicated with myocardial injury. The hs-cTnT and and gender are independent risk factors of prognosis.

Diagnosis and treatment progress of ocular adnexa mucosa-associated marginal zone lymphoma / 白血病·淋巴瘤

Primary ocular adnexal mucosa-associated marginal zone lymphoma is the most common ocular adnexal lymphoma. In recent years, its incidence has been increasing, and some techniques of immunology and molecular biology can make us better identify lymphoma with other lymphadenopathies, and some imaging tools can better judge the stage. In addition to radiotherapy and chemotherapy, antibiotic therapy and immune therapy have made progresses in treatment. This paper reviews the research progress of the diagnosis, staging and treatment of the disease.

Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment / 基因组蛋白质组与生物信息学报·英文版

Variation of maternal gut microbiota may increase the risk of autism spectrum disorders (ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother-child pairs of ASD children and 30 matched mother-child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother-child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation.
