OBJECTIVE:
To summarize and analyze the characteristics of delayed hemolytic transfusion reaction in children, in order to provide a scientific basis for clinical prevention, and ensure the safety of children's blood transfusion.
METHODS:
The basic situation, clinical symptoms and signs, diagnosis time and disappearance time of alloantibody of delayed hemolytic transfusion reaction in children were retrospectively analyzed. The serological test, routine blood test, biochemical detection and urine analysis results were compared pre- and post-transfusion.
RESULTS:
Among 15 164 children with repeated blood transfusion, 23 cases occurred delayed hemolytic transfusion reactions, with an incidence rate of 0.15%, and mainly children with thalassemia and acute leukemia. 39.13% of delayed hemolytic reactions occurred in children with more than 20 times of blood transfusions. Anemia was the main clinical symptom in 86.96% of children. 4.35% of children had hypotension and dyspnea. Serological test results showed that the positive rate of direct antiglobulin test was 91.30%, and that of erythrocyte homologous antibody test was 100%. Erythrocyte alloantibodies were common in Rh and Kidd blood group systems, accounting for 73.91% and 13.04%, respectively. Laboratory test results showed that hemoglobin, reticulocyte, spherocyte, total bilirubin, indirect bilirubin, lactate dehydrogenase, serum ferritin and urine color were significantly different after transfusion compared with those before transfusion (all P <0.05). The average diagnosis time of delayed hemolytic transfusion reactions was 18.56 days, and the average disappearance time of erythrocyte alloantibodies was 118.43 days.
CONCLUSION
The incidence of delayed hemolytic transfusion reaction is high in children with repeated blood transfusion, and the disappearance time of erythrocyte homologous antibody is long. Blood matched ABO, Rh and Kidd blood group antigens should be transfused prophylactically. Once diagnosed, erythrocyte alloantibody corresponding to antigen-negative blood should be used throughout the whole process.

The paper is to establish an UPLC-MS/MS method for the simultaneous determination of 19 components in Microctis Folium from different production areas. The 50% methanol was used as extraction solvent. The Agilent ZORBAX SB C18 (150 mm × 2.1 mm, 1.8 μm) column was used; mobile phase was acetonitrile - 0.1% acetic acid with gradient elution, flow rate was 0.3 mL·min-1, colume temperature was 30 ℃, and the injection volume was 2 μL; electrospray ionizaton source was used and detected in negative ion mode. The results showed that the established UPLC-MS/MS method could well separate the 19 components, and the methodological investigation results of 19 components were good. By means of orthogonal partial least squares discriminant analysis (OPLS-DA), 28 batches of Microctis Folium samples from different production areas can be divided into three categories, Guangdong, Guangxi and Hainan are each classified into one category, and 10 signature compounds which affecting the quality differences of different production areas were screened out. The established method is accurate, reliable, sensitive and reproducible. It can provide a basis for the establishment of the quality standard of Microctis Folium, as well as for safety and quality research.

Platelet-rich plasma (PRP) shows promise as a regenerative modality for mild-to-moderate erectile dysfunction (ED). However, its efficacy in treating severe ED remains unknown. Blood samples from 8-week-old male rats were used to prepare PRP through a two-step centrifugation procedure, followed by chitosan activation and freeze thaw cycle. A hyperhomocysteinemia (HHcy)-related ED model was established using a methionine-enriched diet, and an apomorphine (APO) test was conducted during the 4 th week. APO-negative rats were divided into two groups and were injected with PRP or saline every 2 weeks. Erectile function and histological analyses of the corpus cavernosum were performed during the 16 th week. The results revealed that erectile function was significantly impaired in rats with HHcy-related ED compared to that in age-matched rats but was improved by repeated PRP injections. Immunofluorescence staining revealed a reduction in reactive oxygen species and additional benefits on the recovery of structures within the corpus cavernosum in rats that received PRP treatment compared to those in the saline-injected control group. Therefore, PRP could enhance functional and structural recovery in a severe HHcy-related ED model. A notable strength of the present study lies in the use of a repeated intracavernous injection method, mirroring protocols used in human studies, which offers more reliable results for translating the findings to humans.

OBJECTIVE:
The study explores the effects of electroacupuncture (EA) at the governing vessel (GV) on proteomic changes in the hippocampus of rats with cognitive impairment.
METHODS:
Healthy male rats were randomly divided into 3 groups: sham, model and EA. Cognitive impairment was induced by left middle cerebral artery occlusion in the model and EA groups. Rats in the EA group were treated with EA at Shenting (GV24) and Baihui (GV20) for 7 d. Neurological deficit was scored using the Longa scale, the learning and memory ability was detected using the Morris water maze (MWM) test, and the proteomic profiling in the hippocampus was analyzed using protein-labeling technology based on the isobaric tag for relative and absolute quantitation (iTRAQ). The Western blot (WB) analysis was used to detect the proteins and validate the results of iTRAQ.
RESULTS:
Compared with the model group, the neurological deficit score was significantly reduced, and the escape latency in the MWM test was significantly shortened, while the number of platform crossings increased in the EA group. A total of 2872 proteins were identified by iTRAQ. Differentially expressed proteins (DEPs) were identified between different groups: 92 proteins were upregulated and 103 were downregulated in the model group compared with the sham group, while 142 proteins were upregulated and 126 were downregulated in the EA group compared with the model group. Most of the DEPs were involved in oxidative phosphorylation, glycolipid metabolism and synaptic transmission. Furthermore, we also verified 4 DEPs using WB technology. Although the WB results were not exactly the same as the iTRAQ results, the expression trends of the DEPs were consistent. The upregulation of heat-shock protein β1 (Hspb1) was the highest in the EA group compared to the model group.
CONCLUSION
EA can effect proteomic changes in the hippocampus of rats with cognitive impairment. Hspb1 may be involved in the molecular mechanism by which acupuncture improves cognitive impairment.

OBJECTIVE:
This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.
METHODS:
We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.
RESULTS:
The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.
CONCLUSION
Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

Background:
and Purpose To explore the causal relationships of elements of the exposome with ischemic stroke and its subtypes at the omics level and to provide evidence for stroke prevention. Methods We conducted a Mendelian randomization study between exposure and any ischemic stroke (AIS) and its subtypes (large-artery atherosclerotic disease [LAD], cardioembolic stroke [CE], and small vessel disease [SVD]). The exposure dataset was the UK Biobank involving 361,194 subjects, and the outcome dataset was the MEGASTROKE consortium including 52,000 participants.
Results:
We found that higher blood pressure (BP) (systolic BP: odds ratio [OR], 1.02; 95% confidence interval [CI], 1.01 to 1.04; diastolic BP: OR, 1.03; 95% CI, 1.01 to 1.05; pulse pressure: OR, 1.03; 95% CI, 1.00 to 1.06), atrial fibrillation (OR, 1.18; 95% CI, 1.13 to 1.25), and diabetes (OR, 1.13; 95% CI, 1.07 to 1.18) were significantly associated with ischemic stroke. Importantly, higher education (OR, 0.69; 95% CI, 0.60 to 0.79) decreased the risk of ischemic stroke. Higher systolic BP (OR, 1.06; 95% CI, 1.02 to 1.10), pulse pressure (OR, 1.08; 95% CI, 1.02 to 1.14), diabetes (OR, 1.28; 95% CI, 1.13 to 1.45), and coronary artery disease (OR, 1.58; 95% CI, 1.25 to 2.00) could cause LAD. Atrial fibrillation could cause CE (OR, 1.90; 95% CI, 1.71 to 2.11). For SVD, higher systolic BP (OR, 1.04; 95% CI, 1.00 to 1.07), diastolic BP (OR, 1.06; 95% CI, 1.01 to 1.12), and diabetes (OR, 1.22; 95% CI, 1.10 to 1.36) were causal factors.
Conclusions
The study revealed elements of the exposome causally linked to ischemic stroke and its subtypes, including conventional causal risk factors and novel protective factors such as higher education.

With the population aging, the morbidity and mortality of cancer patients continue to rise. At present, the treatment methods for tumors include surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy. However, most chemotherapeutic drugs can cause severe side effects and drug resistance. Therefore, as an alternative therapy, traditional Chinese medicine (TCM) treatment can effectively relieve the clinical symptoms of tumor patients, improve the quality of life, inhibit or stabilize the development of tumors, and prolong the survival period of patients. Due to the good safety of Chinese medicine, its potential anti-cancer activity has attracted increasing attention. Ganoderma lucidum, a treasure of Chinese medicinal material, is a medicinal fungus with a history of more than 2 000 years in China. So far, many studies have proposed the anti-cancer properties of G. lucidum. G. lucidum has extensive pharmacological activities, such as anti-tumor, anti-atherosclerosis, and anti-aging. It can also regulate immunity, protect the liver and the heart, and reduce blood glucose and lipid. The chemical composition of G. lucidum is complex. At present, it is proved to contain polysaccharides, triterpenoids, alkaloids, nucleosides, amino acids, and various trace elements. The anti-tumor mechanisms of polysaccharides and triterpenoids in G. lucidum are mainly achieved by apoptosis induction, immune regulation, anti-angiogenesis, and induction of cell cycle arrest. Currently, it has been widely used in the adjuvant treatment of complex tumors such as lung cancer, liver cancer, cervical cancer, prostate cancer, breast cancer, and colon cancer. The present study reviewed the bioactivities and mechanisms of triterpenoids and polysaccharides in G. lucidum in recent years and highlighted the anti-tumor effects and mechanisms to provide references for the further development and utilization of G. lucidum.
