OBJECTIVE: To analyze the serological and molecular biological characteristics of 5 patients with cis AB blood group, and to explore the safe transfusion strategy. METHODS: Serological identification of the samples' blood group was performed using anti-A, anti-B, anti-D, anti-A1, anti-H typing reagents and ABO reagent erythrocytes. Molecular biological identification of the samples' blood group was performed using PCR-SSP or gene sequencing. RESULTS: The serological identification results of blood group in 5 patients all showed inconsistent forward and reverse typing, presenting as A₂B₃ or A₂B_w. ABO gene sequencing of samples 1, 2 and 3 showed 261delG in exon 6 and 467C>T, 803G>C in exon 7. The genotypes of samples 1, 2 and 3 were determined to be cisAB/O . PCR-SSP genotyping was performed on sample 4 and 5，and the results were both cisAB/O . CONCLUSION Patients with cisAB alleles have inconsistent serological manifestations, and genetic testing is necessary to ensure the safety and effectiveness of blood transfusion.

The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ² = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ² = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.

Objective To investigate the potential of ginkgolide B(GB)in mitigating vascular endothelial injury by antagonizing endoplasmic reticulum stress(ERS)and elucidate its underlying molecular mechanism.Methods An injury model of human bone marrow-derived endothelial progenitor cells(EPCs)induced by tunica-mycin(TM)was established.Cell proliferation was assessed using MTS assay,while cell viability was determined through Calcein-AM/EthD-I double staining.Transwell assay was employed to evaluate cell migration ability.DCFH-DA staining was utilized to measure intracellular ROS levels,and NADPH activity was quantified via ELISA.JC-1 and DiOC6 staining were performed for qualitative and quantitative assessment of mitochondrial membrane potential respectively.Qrt-pcr analysis was conducted to determine mRNA expression levels,whereas western blot analysis enabled detection of protein expression levels in the cells.Results GB dose-dependently attenuated tunicamycin-induced ERS-mediated endothelial injury in hEPCs,as evidenced by decreased cell viability,impaired cell migration,and angiogenesis inhibition(P<0.01).Furthermore,GB treatment significantly reduced ROS production and NADPH levels within the cells(P<0.01),while also inhibiting ERS-mediated decline in mitochondrial membrane potential concentration-dependently(P<0.01).Additionally,GB inhibited the expression of ERS-related proteins such as GRP78,ATF4,CHOP etc.,regulated apoptosis-related protein Bcl-xl,Bax cleaved caspase-4 cytochrome c;thereby effectively counteracting endoplasmic reticulum stress-induced cellular damage.Conclusions GB exerts a protective effect on vascular endothelium by antagonizing endoplasmic reticulum stress;this mechanism may be attributed to its ability to reduce intracellular reactive oxygen species levels.It also suppresses the expression of ERS-related proteins(CHOP78 and ATF4),and modulates apoptosis-associated proteins(Bcl-xl,Bax,cleaved caspase-4,and cytochrome c).

The present study established the spectrum-effect relationship model of flavonoids in Citri Reticulatae Pericarpium(CRP) from 15 batches of Liujunzi Decoction and statistically analyzed the correlation between chemical peaks and efficacy to identify the main effective components. HPLC fingerprints of flavonoids in CRP from 15 batches of Liujunzi Decoction were established. HPLC analysis was carried out on the Venusil XBP C_(18)(L) column(4.6 mm×250 mm, 5 μm) at 30 ℃ with acetonitrile-water(containing 0.1% formic acid) as mobile phase for gradient elution, a flow rate of 1.0 mL·min~(-1), and detection wavelength of 300 nm to obtain chemical fingerprints. Additionally, the effects of flavonoids from CRP in 15 batches of Liujunzi Decoction on the content of GAS, MTL, and VIP, TFF3 mRNA expression, and percentage of CD3~+ T-cells of model rats with spleen deficiency were determined. The spectrum-effect relationship model was established by gray correlation analysis. The results showed that the main characteristic peaks with great contribution to the regulation of gastrointestinal tract were peak 16(vicenin-2), peak 63(sinensetin), peak 64(isosinensetin), peak 65(nobiletin), peak 67(3,5,6,7,8,3',4'-heptemthoxyflavone), peak 68(tangeretin), and peak 69(5-desmethylnobiletin). Therefore, there was a linear correlation between flavonoids from CRP in Liujunzi Decoction and the efficacy, and the medicinal effect was achieved by multi-component action. This study is expected to provide a new idea for exploring the material basis of the effect, i.e., regulating qi prior to replenishing qi, of CRP in Liujunzi Decoction.

OBJECTIVE: To observe the clinical effect of lever positioning manipulation for the treatment of lumbar disc herniation and its effect on Cobb angle. METHODS: From December 2017 to November 2018, 67 patients with lumbar disc herniation were included in the study. The patients were randomly divided into treatment group and control group by digital table method. There were 34 cases in the treatment group, including 20 males and 14 females, with an average age of (36.09±8.26) years old and a course of (13.79±15.50) months. Treatment group was treated with lever positioning manipulation. There were 33 cases in the control group, including 18 males and 15 females, with an average age of(36.48±7.81) years old and a course of (12.82±15.68) months. Control group was treated with lumbar slanting manipulation. Two groups were treated 3 times a week, once every other day, 6 times for a course of treatment, after 2 courses of treatment, the changes of Cobb angle before and after treatment were compared between two groups by imaging. The symptoms and signs were scored with reference to clinical evaluation standard;overall efficacy was evaluated with reference to "Diagnostic Efficacy Criteria of Traditional Chinese Medicine Syndrome" issued by the State Administration of Traditional Chinese Medicine for lumbar disc herniation. RESULTS: One patient in each group dropped out. The symptom and sign scores of treatment group and control group before treatment were 18.56± 4.81, 18.61±3.72, while after treatment were 9.41±5.19, 13.55±3.68;treatment group was significantly lower than control group after treatment ( CONCLUSION Both the lever positioning manipulation and the lumbar slanting manipulation methods are effective for the treatment of lumbar disc herniation, but clinical effect of lever positioning method on lumbar disc herniation is more significant, and the effect on Cobb angle is more obvious. It is worthy of promotion.

Objective:To explore the relationship between anxiety and mental resilience of caregivers for community-dwelling dementia patients.Methods:Patients in four communities who met the diagnostic criteria for Alzheimer's disease(AD)were randomly selected and their caregivers served as study subjects.General characteristics, anxiety and resilience of caregivers(n=592)were investigated with a questionnaire developed by ourselves, the Generalized Anxiety Disorder-7 Scale(GAD-7), and the Conner-Davidson Resilience Scale(CDRISC).Results:There were 592 subjects in the study, with 185 cases(31.3%)having anxiety.Differences in manifestations of anxiety existed between caregivers for AD patients in different age groups( P<0.01). Anxiety levels were also influenced by AD patient caregivers' gender, educational level and blood relationship to the patient( P<0.05). The differences were reflected in tenacity( F=72.58), strength( F=82.19), optimism( F=12.57)and the total elasticity score( F=162.88). The Spearman correlation was used to analyze the association of caregiver anxiety with caregivers' general characteristics and domains of psychological resilience.The results showed that anxiety was negatively correlated with gender( r=-0.09, P<0.05), education level( r=-0.112, P<0.01), blood relationship( r=-0.122, P<0.01), psychoelasticity and three other domains( r=-0.457, -0.495, -0.208, -0.60, all P<0.01), but was positively correlated with age( r=0.127, P<0.01). Logistic regression analysis showed that psychoelasticity was a protective factor for anxiety in caregivers for community-dwelling AD patients( β=-0.323, P<0.05). Conclusions:While treating Alzheimer's patients, clinicians can consider psychotherapy measures to improve the psychological resilience of their caregivers.
