Objective:To observe the clinical efficacy of fire-needle therapy in treating deglutition disorders due to pseudobulbar palsy in the remission stage of stroke.Methods:Sixty-two eligible subjects were divided into a fire-needle group and a rehabilitation group by a simple randomization method at a ratio of 1:1.The two groups received same basic intervention;in addition,the fire-needle group received fire-needle treatment,while the rehabilitation group received rehabilitation training.The two groups of subjects all received a 3-week treatment and were evaluated by the dysphagia severity rating scale (DSRS),modified Mann assessment of swallow ability (MMASA) and Kubota Toshio swallow test (KTST) before and after the intervention.The complications and adverse events occurred during the trial were recorded.The data were statistically analyzed.Results:At the third week,the DSRS,MMASA and KTST scores changed significantly compared with the baseline in both groups (P＜0.05),and the changes in the fire-needle group were more significant than those in the rehabilitation group (P＜0.05).The between-group comparison at the third week showed that the therapeutic efficacy in the fire-needle group was superior to that in the rehabilitation group (P＜0.05).Conclusion:Fire-needle therapy can obviously change the DSRS,MMASA and KTST scores in pseudobulbar palsy in the remission stage of stroke,and significantly enhance the therapeutic efficacy of the treatment of deglutition disorders in this stage.

BACKGROUNDPatients presenting with severe left ventricular dysfunction (SLVD) undergoing conventional coronary artery bypass grafting (CCABG) are at an increased risk of perioperative mortality and morbidity. The aim of this study was to assess the risk factors responsible for mortality and morbidity among patients with SLVD by comparing CCABG and off-pump coronary artery bypass surgery (OPCAB).

METHODSWe retrospectively evaluated 186 consecutive patients with SLVD who underwent coronary artery bypass grafting (CABG), including 102 by CCABG and 84 by OPCAB. Registry database, medical notes, and charts were studied for preoperative and postoperative data of the patients. Different variables and risk factors (preoperative, intraoperative, and postoperative) were evaluated and compared. The morbidity and mortality outcomes were compared in the two groups. The follow-up results and quality of life were assessed after surgery.

RESULTSThe two groups had similar percentage of patients with preoperative high-risk profiles and no significant differences were found between groups in baseline variables such as age or comorbidities. There was a significant difference in the number of grafts used between the two groups. CCABG patients received (3.6 +/- 0.5) grafts per patient, while OPCAB patients had (2.7 +/- 0.6) grafts (P < 0.05). Completeness of revascularization was also significantly different between the two groups (CCABG 91.1% vs OPCAB 73.8%, P < 0.05). The hospital mortality was similar in the two groups (4.8% in OPCAB vs 5.9% in CCABG). The risk-adjusted mortality, according to the calculated propensity score, did not reach statistical significance in the two groups. In this study, OPCAB seemed to have a beneficial effect on reducing reoperation for bleeding, blood transfusion requirement, and the length of stay at ICU. But the incidence of perioperative myocardial infarction was more common in the off-pump group (P < 0.05). The degree of improvement in angina and quality of life did not differ significantly between the two groups.

CONCLUSIONSUsing cardiopulmonary bypass is not an independent predictor of mortality and morbidity in patients with SLVD. Isolated CABG can be safely performed in SLVD patients with acceptable postoperative morbidity and mortality in addition to encouraging home discharge rates and higher quality of life. Therefore, CCABG remains a viable option in selected patients with SLVD.

Presynaptic dopaminergic PET imaging is a useful method for the diagnosis of parkinsonism. Based on the expert consensus on operation and clinical application of dopamine transporter brain PET imaging technology published in 2020, this paper further recommends the relevant elements of result interpretation of presynaptic dopaminergic PET imaging.

Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron–glia interaction mediated by the C3–TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3–TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

Orthodontically induced tooth root resorption (OIRR) is a serious complication during orthodontic treatment. Stimulating cementum repair is the fundamental approach for the treatment of OIRR. Parathyroid hormone (PTH) might be a potential therapeutic agent for OIRR, but its effects still lack direct evidence, and the underlying mechanisms remain unclear. This study aims to explore the potential involvement of long noncoding RNAs (lncRNAs) in mediating the anabolic effects of intermittent PTH and contributing to cementum repair, as identifying lncRNA-disease associations can provide valuable insights for disease diagnosis and treatment. Here, we showed that intermittent PTH regulates cell proliferation and mineralization in immortalized murine cementoblast OCCM-30 via the regulation of the Wnt pathway. In vivo, daily administration of PTH is sufficient to accelerate root regeneration by locally inhibiting Wnt/β-catenin signaling. Through RNA microarray analysis, lncRNA LITTIP (LGR6 intergenic transcript under intermittent PTH) is identified as a key regulator of cementogenesis under intermittent PTH. Chromatin isolation by RNA purification (ChIRP) and RNA immunoprecipitation (RIP) assays revealed that LITTIP binds to mRNA of leucine-rich repeat-containing G-protein coupled receptor 6 (LGR6) and heterogeneous nuclear ribonucleoprotein K (HnRNPK) protein. Further co-transfection experiments confirmed that LITTIP plays a structural role in the formation of the LITTIP/Lgr6/HnRNPK complex. Moreover, LITTIP is able to promote the expression of LGR6 via the RNA-binding protein HnRNPK. Collectively, our results indicate that the intermittent PTH administration accelerates root regeneration via inhibiting Wnt pathway. The lncRNA LITTIP is identified to negatively regulate cementogenesis, which activates Wnt/β-catenin signaling via high expression of LGR6 promoted by HnRNPK.

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.
