It is believed that the cause of recurrent trigeminal neuralgia is mainly physical injuries and emotional distress. The core pathogenesis lies in the blockage of meridians and disharmony between the body and mind. Therefore， it is proposed that the treatment should focus on simultaneously regulating the body and the mind， with the therapeutic methods of unblocking the meridians and collaterals， soothing the liver and moving qi， and regulating the mind to relieve pain. In clinical practice， liver-soothing and mind-regulating acupuncture combined with para-nerve acupuncture are commonly used， and puncturing upto the bone is applied to strengthen the analgesic effect， providing a new diagnosis and treatment idea for clinical treatment of recurrent trigeminal neuralgia with acupuncture.

OBJECTIVE: To identify the nucleotide sequence of a novel HLA-DRB1*12:106 allele. METHODS: A blood donor who was joined into the database for platelet matching transfusion at the Blood Center of Zhejiang Province in 2023 was selected as the study subject. HLA genotyping was carried out through next-generation sequencing based on AllType NGS 11 locus, AllType FASTPlex NGS reagents, and Sanger sequencing method. The HLA genotype of the donor by Sanger sequencing and next generation sequencing were assigned by using uTYPE 7.3 and TypeStream Visual 3.0 software, respectively. This study was approved by Medical Ethics Committee of the Zhejiang Blood Center (Ethics No. Provincial Blood Center Ethics Review 2022 Research No. 001). RESULTS: A novel HLA-DRB1*12 allele has been identified, and the full coding sequence has been submitted to the GenBank database (No. OR101190), and the length of submitted sequence was 801 bp, which was officially named as HLA-DRB1*12:106 by the WHO Nomenclature Committee for Factors of the HLA System (submission No. HWS10066755). Compared with the sequence of the highest homology (HLA-DRB1*12:01:01:01 allele), a single nucleotide change was identified at position 344 T>G in the exon 2 of the HLA-DRB1*12:106, which has resulted in replacement of Valine by Glycine at residue 86. The HLA genotype of the proband was determined as HLA-A*02:01, 11:01;-B*13:02, 40:01;-C*01:02, 03:03;-DRB1*07:01, 12:106;-DRB3*01:01;-DRB4*01:03;-DQA1*02:01,04:01;-DQB1*02:02,04:02;-DPA1*01:03,01:03; -- DPB1*02:01:02G,04:01:01G. CONCLUSION A novel HLA-DRB1 allele has been identified in the Chinese population. The mutated amino acid, located in the peptide binding region of the β chain, may affect the binding characteristics of antigen peptides.

ObjectiveTo investigate the application of the novel inflammatory factor adsorption column CA280 combined with low-dose plasma exchange （LPE） in patients with acute-on-chronic liver failure （ACLF）. MethodsA prospective cohort study was designed， and a total of 93 ACLF patients who were admitted to The Ninth Hospital of Nanchang from June 2023 to January 2025 were enrolled and randomly divided into DPMAS+LPE group with 50 patients and CA280+LPE group with 43 patients. In addition to comprehensive medical treatment， the patients in the DPMAS+LPE group received DPMAS and LPE treatment， and those in the CA280+LPE group received CA280 and LPE treatment. The two groups were observed in terms of routine blood test results， liver function parameters， renal function markers， electrolytes， coagulation function parameters， cytokines， adverse events， and 28-day prognosis before surgery （baseline）， during surgery （DPMAS or CA280）， and after surgery （after sequential LPE treatment）. The paired t-test was used for comparison of normally distributed continuous data before and after treatment within each group， and the independent-samples t test was used for comparison between groups； the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment within each group， and the Mann-Whitney U test was used for comparison between groups. The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups， and the Spearman test was used for correlation analysis. ResultsAfter CA280 treatment， the ACLF patients had significant reductions in the levels of cytokines （IL-6， IL-8， IL-10， TNF-α， and IFN-γ）， liver function parameters （ALT， AST， ALP， TBil， DBil， Alb， and glutathione reductase）， and the renal function marker urea nitrogen （all P<0.05）， and in terms of coagulation function parameters， there were significant increases in prothrombin time， activated partial thromboplastin time （APTT）， thrombin time， and international normalized ratio （INR） and significant reductions in prothrombin activity （PTA） and fibrinogen （FIB） （all P<0.05）. Compared with the DPMAS+LPE group， the CA280+LPE group showed better improvements in the serum cytokines IL-8 （Z=-2.63， P=0.009）， IL-10 （Z=-3.94， P<0.001）， and TNF-α （Z=-1.53， P=0.023）， and the two artificial liver support systems had a similar effect in improving liver function （ALT， AST， GGT， GR， TBil， and DBil） （all P >0.05）， but the CA280+LPE group showed a significantly greater reduction in Alb （Z=-2.08， P=0.037）. CA280+LPE was more effective in reducing uric acid （Z=-2.97， P=0.003）. Compared with DPMAS+LPE， CA280+LPE treatment resulted in a significant reduction in INR （Z=-4.01， P<0.001）， a significant increase in APTT （Z=-2.53， P=0.011）， and significant greater increases in PTA （Z=-6.28， P<0.001） and FIB （Z=-3.93， P<0.001）. There were no significant differences in the incidence rates of adverse reactions and the rate of improvement at discharge between the two groups （all P>0.05）. The Spearman correlation analysis showed that IL-6 was significantly correlated with WBC （r=0.22， P=0.042）， TBil （r=0.29， P=0.005）， and FIB （r=-0.33， P=0.003）； IL-8 was positively correlated with APTT （r=0.37， P<0.001） and INR （r=0.25， P=0.013）； TNF-α was significantly correlated with WBC （r=0.40， P<0.001） and TBil （r=0.34， P<0.001）. ConclusionCompared with DPMAS， CA280 combined with LPE can effectively clear proinflammatory cytokines and improve liver function in ACLF patients， but it has a certain impact on Alb and coagulation function. This regimen provides a new option for the individualized treatment of ACLF and can improve the short-term prognosis of patients， but further studies are needed to verify its long-term efficacy.

Objective:To investigate the current status of fear of falling in postoperative cardiac surgery patients, and to analyze its influencing factors and interrelationships.Methods:A convenience sample of 246 postoperative cardiac surgery patients hospitalized in the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University, from December 2023 to December 2024 was surveyed. The Body Image Scale, the Personal Mastery Scale, the Fear of Falling Questionnaire-Revised, and a self-designed demographic and clinical questionnaire were used for data collection. Pearson correlation analysis was conducted to examine the relationships among body image, personal mastery, and fear of falling. PROCESS Model 4 was applied to test the mediating role of personal mastery between body image and fear of falling, with bootstrapping for verification.Results:A total of 246 questionnaires were distributed, and 236 valid responses were obtained (valid response rate: 95.93%) . The body image score was (14.02±6.36) , personal mastery score was (20.44±4.16) , and fear of falling score was (38.28±10.83) . Body image was positively correlated with fear of falling ( r=0.324, P<0.01) , while personal mastery was negatively correlated with fear of falling ( r=-0.552, P<0.01) . After controlling for variables with statistically significant differences in univariate analysis (including sex, age, education level, body mass index, history of syncope, pain level, and self-rated preoperative exercise capacity) , PROCESS analysis showed that body image had a direct positive effect on fear of falling ( β=0.288, P<0.05) , and also indirectly affected fear of falling through personal mastery, with the indirect effect accounting for 49.5% of the total effect (0.237/0.525) . Conclusions:Postoperative cardiac surgery patients require improvement in body image, personal mastery, and fear of falling. Understanding how body image influences fear of falling through personal mastery not only enriches theoretical frameworks but also provides guidance for psychological interventions in clinical practice, thereby meeting patients' psychological support needs during rehabilitation.

[Objective] To resolve the ambiguities of HLA genotyping generated by next generation sequencing (NGS) using nanopore sequencing technology. [Methods] A total of 38 samples with ambiguous HLA genotyping by NGS in our laboratory were collected, and HLA-A, -B, -C, -DRB1, -DRB3/4/5, -DQA1, -DQB1, -DPA1 and -DPB1 loci in these samples were amplified using primers in the same commercial NGS HLA genotyping kit, then subjected to third-generation library construction, and sequenced on the nanopore sequencer. The sequencing data were converted into Fastq files and analyzed by software, and the genotypes of 11 HLA loci were obtained. The ambiguities were counted directly. [Results] The high-resolution genotyping at the second domain of 11 HLA loci of 38 samples using the third generation sequencing (TGS) were consistent with the results of the NGS method at a rate of 100%. The genotypes for the HLA-A, -B, -C, -DRB3, -DRB4, -DQA1 and -DPA1 loci by TGS were all only one result, and the discrimination rate for ambiguities of the HLA-A, -B, -C, and -DQA1 loci (all caused by the difficulty in phasing due to the short NGS read length) was 100%. Among the HLA-DRB1, -DRB5, -DQB1 and -DPB1 loci, the discrimination rate of TGS for the ambiguities caused by non-amplification of exon 1 was 0% and by the short NGS read length was 100%. [Conclusion] Nanopore technology was used to identify the ambiguities of 11 HLA loci in this study, and the ambiguities caused by the short read length disadvantage of the NGS method could be solved effectively and the accuracy of HLA genotyping would be improved.

Climate change has led to an increasing frequency and intensity of extreme climate events such as heat and drought extremes with considerable global public health burden. This systematic review collected 87 domestic and international studies from 2000 to 2023, considering the impacts of heat extremes, drought extremes, and compound hot-dry events on infectious diseases attributable to various transmission pathways such as waterborne, foodborne, insect-borne, airborne, and contact-transmitted diseases. Our results showed that high temperature was associated with increased transmission risks of waterborne and foodborne diseases including infectious diarrheal diseases (cholera, dysentery, typhoid, and paratyphoid) and infectious gastroenteritis; vector-borne diseases including dengue fever, Zika virus (ZIKV) disease, chikungunya fever, malaria, West Nile fever, and Rift Valley fever; airborne diseases including influenza-like diseases, influenza A, measles, and mumps; and contact-transmitted diseases including HIV/AIDS, schistosomiasis, and leptospirosis. Additionally, drought conditions also amplified the transmission risks of waterborne and foodborne diseases including cholera, Escherichia coli infection, rotavirus infection, and hepatitis E; vector-borne diseases such as scrub typhus, schistosomiasis, hemorrhagic fever with renal syndrome, and West Nile fever; airborne diseases including meningococcal meningitis, pertussis, measles, and upper respiratory infections; and contact-transmitted diseases such as HIV/AIDS. Along with global warming, the frequency of compound high temperature and drought events shows a considerably increasing trend, causing more adverse health effects than heat or drought alone. However, there is limited research quantifying their effects on infectious diseases. These associations may be mediated through temperature and precipitation on infectious disease pathogens, transmission vectors, population susceptibility, public health services, and behaviors. In the context of climate change, the increasing occurrence of compound events of high temperatures and droughts raises health concerns, and further studies are needed to enhance our understanding of the impacts of climate change on infectious diseases and improve human adaption to climate change.

Objective:To analyze the sequence of a novel HLA- DPB1 allele in an individual. Methods:A individual identified from the database of blood donors for matched platelet transfusion at the Blood Center of Zhejiang Province in May 2022 was selected as the study subject. HLA genotype of the individual was determined by next-generation sequencing (NGS) on an Ion Torrent S5 platform. The sequence of the HLA- DPB1 locus was also determined by NGS on an Illumina Miseq platform and third generation sequencing using Oxford Nanopore MinION. This study was approved by Medical Ethics Committee of the Blood Center of Zhejiang Province (Ethics No. 2021-001). Results:A novel HLA- DPB1*02 allele was identified in the specimen, for which the closest genotype was HLA- DPB1*02: new, 17: 01: 01G, with the variant located in exon 3. Meanwhile, the NGS also revealed a novel HLA- DPB1*17 allele, with the closest genotype being HLA- DPB1*02: 01: 02G, 17: new. Both the HLA- DPB1*17: 01: 01: 01 and novel HLA- DPB1*02 alleles were identified by third-generation sequencing. Compared with the HLA- DPB1*02: 01: 02: 01 allele, the novel allele had a G>A variation at position 369 in the exon 3, which did not result in amino acid change. Conclusion:A novel HLA- DPB1 allele has been identified and validated by both NGS and TGS, which has been named as HLA- DPB1*02: 01: 69 by the World Health Organization Committee on Nomenclature of Factors of the HLA System.
