OBJECTIVE: To explore serological detection and blood transfusion strategies of mimicking antibodies, so as to provide appropriate transfusion strategies. METHODS: Detailed serological tests, including ABO blood group, Rh typing, antibody specificity, etc,were performed on two patients with autoimmune hemolytic anemia(AIHA). Meanwhile, the references about blood transfusion from mimicking antibody patients published from 1977 to 2024 in China and abroad were retrospectively summarized and analyzed. RESULTS: The patient 1 blood type was AB,CCDee and the antibody is mimicking anti-e, transfusion the e-negative red blood cells (RBCs) was effective. After two transfusions of e-RBCs, hemoglobin levels significantly increased from 48 g/L to 91 g/L, with complete resolution of hemolytic symptoms. The patient 2 blood type was O,CcDee, and the antibody was mimicking anti-c, the patient was diagnosed with AIHA and treated with hormone. No blood products were transfused during hospitalization, and his hemolysis was relieved. CONCLUSION Strictly grasping the indication of blood transfusion, blood transfusion should not be performed in the unnecessary conditions, and the corresponding antigen-negative RBC should be screened for transfusion in the necessay conditions.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

To develop a caregiver parenting behavior scale for children aged 2 to 6 years, and to verify its reliability and validity. This study recruited 1 350 caregivers of children aged 2 to 6 years. The item discrimination analysis and exploratory factor analysis were used to analyze the structure, dimensions and items of the scale. Homogeneity reliability, split-half reliability and test-retest reliability were used to analyze the reliability of the scale. Content validity and construct validity were used to analyze the validity of the scale. The results showed that the final scale contained 7 dimensions and 45 items. Cronbach's α coefficient of the total scale was 0.945; the coefficient of split half was 0.899; the test-retest reliability analysis showed that the correlation coefficients between the two tests were 0.893 (total score), 0.854 (social), 0.832 (language), 0.871 (gross motor), 0.893 (fine motor), 0.862 (cognitive), 0.832 (self-care), and 0.872 (sensory). The content validity analysis was carried out by two rounds of expert argumentation using Delphi expert consultation method. The Kendall coefficient of the items score in two rounds of Delphi expert consultation was 0.813 (P<0.01). The structure validity analysis showed that there were significant correlations between each dimension and the total scale, also between each dimension of the scale, and the extracted average variance values of each dimension was greater than the correlation coefficients between this dimension and other dimensions. In conclusion, the reliability and validity of the scale are qualified. It can be used as a tool to evaluate and guide the parenting behavior of caregivers of children aged 2 to 6 years.

TCP (teosinte branched1/cincinnata/proliferating cell factor) is a group of plant-specific transcription factors that play important roles in plant growth and development. To date, there are no report about TCP transcription factors in eggplant (Solanum melongena L). In this study, twenty-nine eggplant TCP (SmTCP) family genes distributed on 11 chromosomes were identified from the genome database of eggplant using bioinformatics methods. The results showed that all members of the family contained sequences encoding TCP conserved domains with length of amino acids ranging from 201 to 538 and exon numbers of 1 or 2. Subcellular localization revealed that three SmTCP proteins (SmTCP02/03/21) were located in the cytoplasm and the other SmTCP proteins were located in the nucleus. The 29 TCP transcription factors were divided into ClassⅠ (PCF) and ClassⅡ (CIN and CYC/TB1) by phylogenetic tree and sequence analysis. Collinearity analysis showed that 17 pairs (21) of SmTCP genes had collinearity, and these collinearity genes belonged to segmental duplication. Analysis of gene expression patterns showed that all 29 members of SmTCP gene family were expressed in 15 tissues or organs, but the expression patterns were different. Among them, four gene (SmTCP18/19/20/25) of CIN subfamily were highly expressed in leaves at different growth stages. Analysis of cis-acting elements in the promoter region of SmTCP showed that there were four types of cis-acting elements, which were light response related cis-acting elements, growth and development related cis-acting elements, hormone response related cis-acting elements and stress related cis-acting elements. In summary, the molecular basis of SmTCP genes in eggplant and the influence of TCP gene on the growth and development of eggplant provided a theoretical basis for molecular breeding of eggplant.

OBJECTIVE: To investigate the effects of oridonin (ORI) on the proliferation and apoptosis of human multiple myeloma cell line H929 and its possible mechanism. METHODS: H929 cells were exposed to ORI 0、4、8、12、16、20、24、28、32 μmol/L for 12, 24 and 36 hours respectively. The prolifcration inhibitory effect of ORI on H929 cells was determined by MTT assay and then the working concentrations of ORI were determined. The morphological changes and apoptosis of H929 cells were observed by TUNEL (TdT-mediated dUTP Nick-End Labeling) and fluorescence microscopy. The apoptosis rate of H929 cells was detected by flow cytometry with Annexin V-FITC/PI staining. The protein expressions of pro-caspase-3, BCL-2，p-PI3K, p-Akt, BAX, Cleaved PARP and p-JNK, p-ERK and p-p38 in H929 cells were detected by Western blot. RESULTS: Compared with the control group, the proliferation of H929 cells treated with the ORI of 8-16 μmol/L was significantly inhibited and the apoptosis of H929 cells was obviously increased in dose- and time-dependent manners. As for morphological changes, the characteristics of apoptotic cells were presented in H929 cells treated with ORI for 24 hours. The protein levels of pro-caspase-3, BCL-2，p-PI3K, p-Akt were down-regulated with increasing of ORI concentration（r=0.9861, r=0.9725, r=0.9413, r=0.9373）, while the BAX, Cleaved PARP and p-JNK, p-ERK and p-p38 were up-regulated（r=0.9178, r=0.8877, r=0.882, r=0.9645, r=0.8623）. CONCLUSION The ORI possesses anti-myeloma effects, can inhibit the proliferation and induce the apoptosis of H929 cell line in vitro. Its potential mechanism may be related with up-regulating the MAPK and down-regulating the PI3K/Akt signal pathways.

Objective: To observe the efficacy of preoperative prehabilitation on nutritional status and body composition of patients with esophageal cancer after operation. Methods: A total of 100 patients with esophageal cancer were randomly divided into the study group A and the control group B. The study group received prehabilitation from the day they adimitted to hospital and the control group received common preoperative preparation. The preoperative baseline data and postoperative indicators including levels of serum albumin, prealbumin, transferrin were recorded the day admitted to hospital and the 1, 3, 7, 30th day after surgery. Record the prognosis of the patients (albumin supplementation, incidence of postoperative complications, ICU monitoring time, total cost of hospitalization). And the body composition was examined on the day admitted to hospital and the 7, 30th day after surgery with BIA. Results: The level of serum albumin, prealbumin, transferrin and body composition were no statistically significant difference between the study group and the control group. Compared with the control group, the level of prealbumin were significantly higher in the study group on the 1, 3, 7, 30th day after surgery. The level of serum albumin, transferrin were also significantly higher in study group on the 3, 7, 30th day after surgery. The body composition was no significant difference between the two groups on the 7th day postoperatively. However, the loss of body composition such as skeletal muscle, body water, intracellular water, protein level and body cell volume were less in the study group compared with the control group on the 30th day after surgery. The incidence of postoperative complications in the prehabilitation group, ICU monitoring time, and hospitalization costs were significantly less than those in the control group. Conclusion: Prehabilitation intervention can obviously improve the nutritional status and the prognosis of the patients with esophageal cancer, and reduce the loss degree of their body composition.

Objective Blood-brain barrier(BBB)may stop over 95%of the drugs delivered from entering the brain.This study aimed to establish a BBB model in vitro,detect the ability of the nano drug delivery system to penetrate the BBB,and observe its effect on angiogenesis and neuron cell proliferation after cerebral infarction. Methods A BBB model was established in vitro and the penetrability of PHRO through the BBB was detected by transwell assay.PBS,Rg1,and PHRO were placed in the upper chamber,and the content of Rg1 in the lower chamber was measured by HPLC.The effect of PHRO on angiogenesis was assessed with the in vitro tube formation model and the expression levels of the angiogenesis -related genes VEGFA and Dll4 determined by real time fluorescence quantitative PCR.Brain endothelial cells were incubated with 10 μL PBS(the control group),10 μmol/L Rg1(the Rg1 group),and PHRO(containing 10 μmol/L Rg1,the PHRO group)for 24 hours,and the SH5Y cells incubated the same way in the three groups for 72 hours.The effects of PHRO on the proliferation and apoptosis of the SH5Y cells were detected by MTT assay and flow cytometry respectively.The SH5Y cells were treated with 10 μL PBS(the PBS con-trol group),1 mmol/L Na2S2O4(the hypoxia-induction group),1 mmol/L Na2S2O4plus 10 μmol/L Rg1(the hypoxia-induction +Rg1 group),and 1 mmol/LNa2S2O4plus PHRO(including10 μmol/L Rg1,the hypoxia-induction +PHRO group), respectively. Results The content of Rg1 was 3.18%in the Rg1 group,28.8%in the PHRO group,and 0 in the control group.The angiogenesis of endothelial cells was markedly increased in the Rg 1 group as compared with the control(P<0.05), and even more significantly in the PHRO than in the Rg1 group(P<0.05).In comparison with the control group,the expressions of VEGFA and Dll 4 and the prolif-eration of the SH5Y cells were remarkably elevated in the Rg 1 group(P<0.05)and even more significantly in the PHRO than in the Rg1 group(P<0.05).The apoptosis rate of neurons was the lowest in PBS control(1.2%)and the highest in the hypoxia-induction group(21.6%),decreased to 13.14%and 8.25%in the hypoxia-induction +Rg1 and hypoxia-induction +PHRO group,respectively. Conclusion PHRO nanomedicine could penetrate the blood-brain barrier in vitro, promote angiogenesis and neuronal proliferation, reduce the apoptosis of neurons under hypoxia,and up-regulate the expressions of angiogenesis-related genes.
