The paper introduces the experience of Professor LI Rui in treatment of diseases with bloodletting therapy. Regarding acupoint selection, the main acupoints are selected from the meridians containing excessive blood based on the identification of pathogenesis, and the back-shu points of the foot-taiyang bladder meridian are predominant. The acupoints (e.g. Geshu [BL17], Xuehai [SP10] and Weizhong [BL40]) acting on blood regulations are frequently selected, and the acupoints from the governor vessel (e.g. Dazhui [GV14], Zhiyang [GV9] and Yaoyangguan [GV3]) are specially used for regulating yang qi. Besides, the five-shu points and local points are combined in the prescriptions. This paper expounds the connotation of bloodletting therapy, explores the basis of acupoint selection and clinical application characteristics, and analyzes the clinical cases, so as to provide the approaches to acupoint selection for the clinical application of bloodletting therapy.

The NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome, a high-molecular-weight protein complex in the cytoplasm, is composed of three core components: the sensor protein NLRP3, the adaptor protein apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC) and the effector protein caspase-1. It plays a critical role in regulating host immune and inflammatory responses. Studies have shown that the NLRP3 inflammasome has increasingly become a focal point in tumor molecular biology field. A growing body of evidence indicates that the increased expression and activation of the NLRP3 inflammasome is closely associated with the pathogenesis of head and neck squamous cell carcinoma (HNSCC) and the tumor microenvironment (TME). It may promote tumor proliferation, invasion, migration, and other biological behaviors through various regulatory mechanisms while influencing tumor immune evasion and therapy resistance, which holds promise as a prognostic biomarker for patients. This review explores the current effect and mechanism of the NLRP3 inflammasome and its signaling pathways in head and neck cancer, providing insights into clinical targeted drug development and molecular immunotherapy.

Objective:To evaluate the feasibility and clinical efficacy of transoral endoscopic-assisted submandibular gland resection with low-temperature plasma knife technology, aiming to establish a scarless surgical approach to meet the patients aesthetic demands. Methods:A retrospective analysis was conducted on 5 consecutive patients with benign submandibular gland pathologies treated by a single surgical team between January 2021 and December 2023. All procedures employed a transoral mucosal incision in the floor of mouth, with 0-degree high-definition endoscope assistance and low-temperature plasma knife for precise dissection and hemostasis. Close postoperative follow-up was performed. A systematic literature review compared surgical approaches regarding critical anatomical landmarks, complication profiles, and scar formation. The clinical efficacy of this technique was summarized and analyzed. Results:Successful transoral endoscopic plasma knife resections were performed for benign submandibular conditions（including neoplasms, chronic sialadenitis, and sialolithiasis）. All operations were completed without conversion to open approach. No permanent lingual nerve or marginal mandibular nerve injuries occurred. Transient lingual hypoesthesia recovered within 2 weeks. During 6-12 months follow-up, there was no recurrence and absence of visible cervical scarring, with 100% patient satisfaction regarding cosmesis. Conclusion:Transoral endoscopic plasma knife resection of the submandibular gland demonstrates procedural safety and technical feasibility. This approach offers significant advantages in minimally invasive access, superior aesthetic outcomes, and accelerated recovery, representing a viable novel alternative for benign submandibular gland disease management.

Objective To assess short-and long-term changes in the upper airway,natural head position and hyoid bone position in skeletal Class Ⅲ patients after bimaxillary surgery.Methods In this retrospective study,the cone-beam computed tomography(CBCT)of skeletal Class Ⅲ patients was taken before surgery(T0),3 months after surgery(T1)and 2 years after surgery(T2).Three-dimensional images were created to assess postoperative changes and the correlation between the upper airway,natural head posi-tion and hyoid bone was analyzed.Results Thirty skeletal Class Ⅲ patients(13 men and 17 women)who underwent bimaxillary sur-gery with a mean(SD)age of 21 years(a range of 17-30 years)were evaluated.A significant decrease was observed in the volume of palatopharynx,glossopharynx and total airway after T1 and T2.There was a significant correlation between changes in the position of the mandible and changes in the volume of the upper airway(P＜0.05).The NSL/OPT angle and the NSL/CVT angle were greater after Tl and T2.The change in the NSL/CVT angle was positively correlated with the change in palatopharyngeal and glossopharyngeal volume(P＜0.05).Conclusion Bimaxillary surgery may cause a decrease in upper airway volume,an increase in the cranio-cervical angle,and a downward and backward movement of the hyoid bone.Changes in the cranio-cervical angle may cause changes in the upper air-way.

By consulting the ancient and modern literature， the textual research of Pharbitidis Semen has been conducted to clarify the name， origin， distribution of production areas， quality specification， harvesting， processing and so on， so as to provide reference for the development and utilization of the relevant famous classical formulas. Through textual research， it can be seen that Pharbitidis Semen was first published in Mingyi Bielu（《名医别录》）， and all dynasties have taken Qianniuzi as the correct name. Based on the original research， the main source of Pharbitidis Semen used in previous dynasties is the dried mature seeds of Pharbitis nil， which is consistent in ancient and modern times. The white Pharbitidis Semen appearing in Compendium of Materia Medica（《本草纲目》） from Ming dynasty is similar to the present P. purpurea. It is produced all over the country， and the quality is better if the particles are full and free of impurities. In ancient times， the harvesting time was mostly in the September. Now it is autumn. The fruits are ripe and harvested， dried to remove impurities for standby. In ancient times， the processing methods of Pharbitidis Semen were mainly wine steaming， steaming and frying until half cooked and grinding the head and end. In modern times， they have been simplified to stir-frying method. The nature， taste， meridian tropism and their effects also change supplements with the deepening of practice. Before the Ming dynasty， they were all bitter， cold and toxic. In the Ming dynasty， there appeared the characteristics of pungent， hot and small poisonous. The efficacy has evolved from controlling low Qi， curing foot edema， removing wind toxin， and facilitating urination to facilitating water and defecation， eliminating phlegm and drinking， and eliminating accumulated insects. The main clinical contraindications are those with weak spleen and kidney， those with weak spleen and stomach， pregnant women， and should not be used with croton and croton cream. Based on the textual research， it is suggested that when developing the classic famous formula with Pharbitidis Semen as the main raw material in the future， it is clear that the source should be the dried mature seeds of Pharbitis nil（black product is its black-brown seeds， white product is its beige seeds）. The processing requirements indicated in the original formula are all processed according to the requirements， and the raw product is recommended to be used as medicine if not specified.

ObjectiveTo explore whether miR-375 regulates the malignant characteristics of osteosarcoma (OS) by influencing the expression of MMP13. MethodsPlasmid DNAs and miRNAs were transfected into OS cells and HEK293 cells using Lipofectamine 3000 reagent. Real-time quantitative polymerase chain reaction was performed to measure the expression of miR-375 and MMP13 in OS patients and OS cells. Western blot was performed to analyze the MMP13 protein in the patients with OS and OS cells. The targeting relationship between miR-375 and MMP13 was analyzed by luciferase assay. Migration and invasion were analysed by heal wound and transwell assays, respectively. ResultsmiR-375 expression in OS tissues was lower than that in normal tissues. The expression of MMP13 was upregulated in OS tissues. MMP13 expression was negatively correlated withmiR-375 expression in patients with OS. Migration and invasion were significantly inhibited in OS cells with the miR-375 mimic compared with OS cells with the miRNA control. MMP13 partially reversed the inhibition of migration and invasion induced by miR-375 in the OS cells. ConclusionmiR-375 attenuates migration and invasion by downregulating the expression of MMP13 in OS cells.

BACKGROUND:Alzheimer's disease is a degenerative neurological disorder characterized primarily by cognitive impairment.Acupuncture is a kind of traditional Chinese medicine therapy for treating Alzheimer's disease,but its mechanism is not yet clear. OBJECTIVE:To observe the effects of electroacupuncture with"Zhi San Zhen"on the Notch signaling pathway,β-amyloid protein(Aβ)and synaptic plasticity in 5xFAD mice. METHODS:Sixteen male,6-month-old 5xFAD mice,SPF-grade,were randomly divided into the electroacupuncture with"Zhi San Zhen"group(electroacupuncture group)and the model group,with eight mice in each group.Eight SPF-grade,male,6-month-old C57BL/6 mice were used as the wild control(wild)group.The electroacupuncture group received electroacupuncture with"Zhi San Zhen"intervention,5 times a week for 4 consecutive weeks.The model group and the wild group did not receive electroacupuncture intervention.The Morris water maze was used to preliminarily assess their learning and memory abilities.Thioflavin S staining was performed to detect Aβ plaque deposition.Western blot and real-time quantitative polymerase chain reaction(RT-qPCR)were used to measure the expression levels of transmembrane receptor protein Notch-1,Notch 1 intracellular domain(NICD),hairy and enhancer of split 1(Hes 1),hairy and enhancer of split 5(Hes 5),synaptophysin(SYN),postsynaptic density protein-95(PSD-95),and Aβ. RESULTS AND CONCLUSION:Compared with the model group,the wild group and the electroacupuncture group showed shortened escape latency,increased platform crossing times,and longer target quadrant dwell time(P<0.05).Compared with the wild group,the model group had significantly increased deposition of Aβ plaques,while electroacupuncture with"Zhi San Zhen"inhibited the deposition of Aβ plaques in the hippocampus of 5xFAD mice(P<0.05).Compared with the wild group,the model group had decreased mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased mRNA levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"increased the mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue,and decreased the mRNA level of Aβ(P<0.05).Compared with the Wild group,the model group had decreased protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased protein expression levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"upregulated the protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5,and inhibited the protein expression of Aβ(P<0.05).To conclude,electroacupuncture with"Zhi San Zhen"can improve the learning and memory abilities of 5xFAD mice,possibly by inhibiting the deposition of Aβ protein and activating the Notch signaling pathway in the hippocampus to enhance synaptic plasticity.
