ObjectiveTo observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke. MethodsA prospective study was conducted on 160 patients with post-stroke dysphagia， who were randomly divided into a treatment group and a control group， with 80 cases in each group. The control group received conventional rehabilitation training， while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan （CV 23） on the basis of conventional rehabilitation training， for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment， and assessed the swallowing function including videofluoroscopic swallowing study （VFSS）， standardized swallowing assessment （SSA） and functional oral intake scale （FIOS）， swallowing contrast test including hyoid maximum displacement （HmaxD）， pharyngeal transit time （PTT）， and upper esophageal sphincter （UES） opening， surface electromyography （sEMG） test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire （SWAL-QOL） score of the patients in both groups before treatment， after 2 weeks and 4 weeks of treatment， respectively. ResultsThe total effective rate in treatment group was 82.50% （66/80）， significantly higher than 66.25% （53/80） in control group （P＜0.05）. The VFSS， and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment （P＜0.05）， while SSA scores， PTT， and swallowing duration were decreased compared within group before treatment （P＜0.05）. VFSS and FOIS scores， UES opening rate and HmaxD， sEMG maximal amplitude values， and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher （P＜0.05）， while SSA scores， PTT， and swallowing duration were lower （P＜0.05） than those in the control group at the same time. ConclusionCombined tongue three-needle acupuncture and acupoint application on Lianquan （CV 23） for patients with dysphagia after ischemic stroke can significantly improve swallowing activities， and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Drug-drug interaction (DDI) refers to the interaction between two or more drugs in the body, altering their efficacy or pharmacokinetics. Fully considering and accurately predicting DDI has become an indispensable part of ensuring safe medication for patients. In recent years, many deep learning-based methods have been proposed to predict DDI. However, most existing computational models tend to oversimplify the fusion of drug structural and topological information, often relying on methods such as splicing or weighted summation, which fail to adequately capture the potential complementarity between structural and topological features. This loss of information may lead to models that do not fully leverage these features, thus limiting their performance in DDI prediction. To address these challenges, we propose a relation-aware cross adversarial network for predicting DDI, named RCAN-DDI, which combines a relationship-aware structure feature learning module and a topological feature learning module based on DDI networks to capture multimodal features of drugs. To explore the correlations and complementarities among different information sources, the cross-adversarial network is introduced to fully integrate features from various modalities, enhancing the predictive performance of the model. The experimental results demonstrate that the RCAN-DDI method outperforms other methods. Even in cases of labelled DDI scarcity, the method exhibits good robustness in the DDI prediction task. Furthermore, the effectiveness of the cross-adversarial module is validated through ablation experiments, demonstrating its superiority in learning multimodal complementary information.

Acute lung injury (ALI) is a significant complication of sepsis, characterized by high morbidity, mortality, and poor prognosis. Neutrophils, as critical intrinsic immune cells in the lung, play a fundamental role in the development and progression of ALI. During ALI, neutrophils generate neutrophil extracellular traps (NETs), and excessive NETs can intensify inflammatory injury. Research indicates that Taohe Chengqi decoction (THCQD) can ameliorate sepsis-induced lung inflammation and modulate immune function. This study aimed to investigate the mechanisms by which THCQD improves ALI and its relationship with NETs in sepsis patients, seeking to provide novel perspectives and interventions for clinical treatment. The findings demonstrate that THCQD enhanced survival rates and reduced lung injury in the cecum ligation and puncture (CLP)-induced ALI mouse model. Furthermore, THCQD diminished neutrophil and macrophage infiltration, inflammatory responses, and the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α). Notably, subsequent experiments confirmed that THCQD inhibits NET formation both in vivo and in vitro. Moreover, THCQD significantly decreased the expression of peptidyl arginine deiminase 4 (PAD4) protein, and molecular docking predicted that certain active compounds in THCQD could bind tightly to PAD4. PAD4 overexpression partially reversed THCQD's inhibitory effects on PAD4. These findings strongly indicate that THCQD mitigates CLP-induced ALI by inhibiting PAD4-mediated NETs.

This study investigates the clinical differentiation and treatment strategies for bipolar disorder （BD） by analyzing the relationship of its core pathomechanisms including qi stagnation， blood stasis， phlegm turbidity， and heat constraint with bile acid metabolism. The imbalance of "yin in form and yang in function" leads to qi stagnation， blood stasis， phlegm turbidity， and heat constraint， which are critical in the pathogenesis and progression of BD. Bile acids regulate neuroinflammation， neural plasticity， and intestinal flora homeostasis through receptor-mediated pathways. It is believed that the physiological functions of bile acids concretely embody the concept of the "liver is yin in form and yang in function" theory. Clinically， prescriptions such as Sini Powder （四逆散） with the function of venting pathogen and resolving constraint， Wendan Decoction （温胆汤） of drying dampness and resolving phlegm， Longdan Xiegan Decoction （龙胆泻肝汤） of clearing liver and draining fire， and Huanglian Ejiao Decoction （黄连阿胶汤） of nourishing yin and blood can be used to nourish liver yin and restore liver yang function. These strategies may improve BD prognosis by modulating bile acid synthesis and metabolism.

Objective:To explore the impact of CACNA1C rs58619945 genotype on the cortical thickness of attentional networks in patients with Bipolar 1 disorder type (BD-Ⅰ). Methods:From August 2013 and August 2019, a total of 155 BD-Ⅰ patients were recruited from the outpatient and inpatient Departments of the Affiliated Brain Hospital of Guangzhou Medical University, along with 82 healthy controls (HC) from the community and university. Genotype for the CACNA1C rs58619945 locus was determined for all BD-I patients and HC subjects, followed by 3.0 T magnetic resonance imaging scans to measure the cortical thickness in the alert, orienting, and executive control subnetworks. General linear models (GLMs) were used to evaluate the impact of CACNA1C rs58619945 on the cortical thickness of attentional networks. Concurrently, attentional dimension functions were assessed using repeatable battery for the assessment of neuropsychological status (RBANS) and Cambridge neuropsychological test automated battery rapid visual information processing (CANTAB RVP) test. This study was approved by the Medical Ethics Committee of the Affiliated Brain Hospital of Guangzhou Medical University(Ethics No. 2023-056). Results:Compared with the HC group, the BD-Ⅰ patients had shown reduced thickness in bilateral prefrontal cortex, bilateral posterior cingulate cortex, and bilateral superior temporal cortex( P<0.05). A significant interaction between the CACNA1C genotype and the cortical thickness(HC vs.BD) of right prefrontal cortex, right posterior parietal cortex and right superior temporal cortex was noted( P<0.05). Partial correlation analysis has demonstrated a significant correlation between CANTAB RVP and RBANS attention indices and cortical thickness in the right prefrontal cortex, right posterior cingulate cortex( P<0.05), and right superior temporal cortex predominantly among carriers of the BD-Ⅰ G allele. Conclusion:The G allele of CACNA1C rs58619945 is associated with cortical thickness of the right prefrontal cortex, right posterior cingulate cortex, and right superior temporal cortex in BD-Ⅰ, which are part of the alerting and orienting network.

Objective To investigate the effect of Danggui Shaoyao powder on apoptosis of cochlear spiral ganglion cells of age-related hearing loss mice by regulating the inhibitor of kappa B kinase(IKK)/inhibitory subunit of nuclear factor-kappa B alpha(IκBα)/nuclear factor-kappa B(NF-κB)pathway.Methods A total of 48 C57BL/6J mice were randomly divided into age-related hearing loss model group(model group),low-dose Danggui Shaoyao powder group(traditional Chinese medicine-L group,3.2 g/kg crude drug),high-dose Danggui Shaoyao powder group(traditional Chinese medicine-H group,6.4 g/kg crude drug),and high-dose Danggui Shaoyao powder+IKK/IκBα/NF-κB signaling pathway activator resveratrol(RES)group(tradi-tional Chinese medicine-H+RES group,6.4 g/kg crude drug+43.33 mg/kg RES),with 12 mice in each group.Twelve 2-month-old C57BL/6J mice were selected as the control group.Auditory brain stem response(ABR)was used to detect the audi-tory threshold of mice in each group.HE staining was used to observe the pathological changes of spiral ganglions of the mouse cochlea,and the number of spiral ganglion cells in the middle and bottom gyrus of the mouse cochlea was counted.The apoptosis of spiral ganglion cells in mouse cochlea was detected by TUNEL staining.The levels of malondialdehyde(MDA)and superoxide dismutase(SOD)in mouse cochlear tissue were detected by ELISA.The mRNA levels of IL-1β,IL-6 and TNF-α in mouse co-chlear tissues were detected by qRT-PCR.Western blot was used to detect the expression of IKK/IκBα/NF-κB pathway and ap-optosis related proteins in mouse cochlear tissue.Results Compared with the control group,the auditory thresholds at 8 kHz,16 kHz,24 kHz,and 32 kHz,the number of TUNEL positive cells in the cochlear spiral ganglion tissue,the level of MDA,and the mRNA level of IL-1β,IL-6 and TNF-α in the cochlear tissue,the expression of p-IκBα,apoptosis protein(Bax,and cleaved-Caspase-3),and the phosphorylation levels of IKK and NF-κB p65 in the model group were significantly increased(all P＜0.05),the number of cochlear spiral ganglion cells,the level of SOD,and the expression of IκBα protein were significantly re-duced(all P＜0.05),the morphology of cochlear spiral ganglion cells was abnormal,with loose and disordered arrangement,re-sulting in vacuolization and pathological damage.The changes in corresponding indicators of mice in the traditional Chinese med-icine-L group and traditional Chinese medicine-H group were opposite to those in the model group(all P＜0.05).RES alleviated the inhibitory effect of Danggui Shaoyao powder on the apoptosis of cochlear spiral ganglion cells in age-related hearing loss mice.Conclusion Danggui Shaoyao powder may inhibit apoptosis of cochlear spiral ganglion cells of age-related hearing loss mice by downregulating the IKK/IκBα/NF-κB pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the safety and effectiveness of single posterior osteotomy in the correction of rigid cervical spine deformities (CSD) and to explore the indications and key surgical techniques involved.Methods:A retrospective analysis was conducted on the clinical data of 9 patients with rigid CSD who underwent single posterior osteotomy correction between June 2012 and June 2023 in the Department of Spine Surgery at the First Affiliated Hospital of Xinjiang Medical University. The cohort comprised 4 males and 5 females, with a mean age of 19.8±27.2 years (range, 7-48 years). Among these, 5 cases were congenital CSD, 3 were post-tuberculosis deformities, and 1 was iatrogenic. Various coronal and sagittal alignment parameters were measured, including C 1, 2 angle, cervical lordosis (CL), structural scoliosis angle (SSA), structural kyphosis angle (SKA), head tilt (HT), C 2-C 7 sagittal vertical axis (CSVA), sagittal vertical axis (SVA), coronal balance distance (CBD), T 1 slope (T 1S), and the difference between T 1 tilt and cervical lordosis (T 1S-CL). Clinical outcomes were assessed using the neck disability index (NDI), visual analogue scale (VAS), and Scoliosis Research Society-22 questionnaire (SRS-22). Results:The average operation time was 273.9±76.1 min, with an average blood loss of 472.2±128.8 ml. All 9 patients were followed up for an average of 45.2±41.8 months (range, 12-116 months). A total of 7 patients underwent single-segment osteotomies (C 3, C 6 and C 7: 1 case each; C 5: 4 cases), and 2 patients underwent double-segment osteotomies (C 2 and C 7, C 3 and C 4). Four cases involved pedicle subtraction osteotomy (PSO), while 7 cases required vertebral column resection. The upper instrumented vertebra (UIV) was located at the occiput in 1 case and in the cervical spine in 8 cases. The lower instrumented vertebra (LIV) was located in the upper thoracic spine in 6 cases and in the cervical spine in 3 cases, with 2 of the latter cases having both UIV and LIV in the cervical spine. The average number of fused segments was 7.6±4.4 segments (range, 2-12 segments). All patients achieved successful bone fusion within an average of 8.8±3.2 months (range, 6-12 months). Preoperatively, the mean values for CL, SSA, SKA, HT, and CBD were 19.8° (17.2°, 30.5°), 27.4°(23.3°, 30.4°), 28.4°(25.6°, 30.1°), 9.0°(6.2°, 12.3°), and 18.5(12.3, 23.6) mm, respectively. Postoperative improvements were noted with values of -11.1°(-8.8°, -14.4°), 1.3°(0.8°, 1.6°), -11.1°(-8.6°, -14.5°), 1.6°(0.5°, 2.2°), and 9.4 (4.8-13.5) mm, respectively. At the final follow-up, these parameters were maintained, with values of -11.0°(-8.8°, -14.3°), 1.2°(0.8°, 1.5°), -11.0° (-8.6°, -14.3°), 1.5°(0.5°, 2.2°), and 9.4(4.8, 13.4) mm, respectively. Statistically significant improvements were observed between preoperative and postoperative measurements ( P<0.05), except for C 1, 2 angle, CSVA, SVA, T 1S, and T 1S-CL ( P>0.05). NDI and SRS-22 scores showed significant improvements postoperatively ( P<0.05), while VAS scores did not show a significant change ( P>0.05). Postoperative complications included transient nerve injury in two patients, one case of right central retinal artery occlusion, and one case of vertebral artery injury. Conclusion:This study confirms the safety and efficacy of single posterior osteotomy for treating rigid CSD of various etiologies. Standard PSO or modified techniques are effective for correcting cervical kyphosis, while hemivertebra resection and concave-side distraction are recommended for congenital scoliosis or kyphoscoliosis.

Objective To explore the correlation of MPV,NLR,PT,APTT and FIB with early pro-gression of ACI in patients with BAD.Methods A total of 303 ACI patients with BAD admitted in our department of neurology from October 2021 to September 2023 were consecutively recrui-ted,and according to their progression within 7 d of onset,they were divided into progression group(89 cases)and un-progression group(214 cases).The general clinical data,blood routine re-lated indicators(MPV,NLR)and coagulation related indicators(PT,APTT,FIB)were compared between the two groups.Multivariate logistic regression analysis was applied to identify the rela-tionship of above indicators with early progression of ACI in BAD patients.ROC curve was plot-ted to analyze the predictive value of the indictors for disease progression in these patients.Results The progression group had significantly advanced age,larger proportions of diabetes,hyperlipi-demia and stroke history,and increased levels of uric acid,LDL-C,homocysteine,MPV,platelet distribution width,NLR,D-dimer and FIB,and shorter TT,PT and APTT when compared with the un-progressed group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that MPV,NLR,PT,APTT,and FIB were all independent influencing factors for early disease pro-gression of ACI in patients with BAD(P＜0.05,P＜0.01).ROC curve indicated that the AUC value of combined MPV,NLR,PT,APTT and FIB in detecting early disease progression was 0.859(95％CI:0.813-0.905).Conclusion Blood routine(MPV,NLR)and coagulation related indicators(PT,APTT,FIB)are closely associated with the early disease progression of ACI in BAD patients,and these indicators are of high value in predicting the early disease progression.
