Objective To explore the clinical efficacy of the medicated stick massage at meridian knot points in treating Qi stagnation and blood stasis type lumbar disc herniation(LDH)based on the meridian theory.Methods The patients with LDH in the ward 5 of orthopedics department in this hospital from Sep-tember 2024 to April 2025 were selected as the research subjects.On the basis of routine treatment and care,the control group adopted the medicated stick massage at points,while the experimental group adopted the medicated stick massage at meridian knots.The visual analogue scale(VAS)scores,Japanese Orthopaedic So-ciety(JOA)score,TCM syndrome scores and TCM syndrome therapeutic effects before intervention and in two weeks after intervention were compared between the two groups.Results The VAS scores,each item score and total score of JOA,TCM syndrome scores and TCM therapeutic effects after 2-week intervention in the experimental group all were superior to those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Selecting the medicated stick massage at the meridian knots under the guidance of meridian theory could significantly improve the pain symptoms,lumbar function,TCM syndrome scores,the therapeutic effects are definite,and is worthy of clinical promotion and application.

BACKGROUND:Patients with lumbar disc herniation have different physical deformities due to nucleus pulposus compression and mechanical imbalance. On this basis,Professor Feng Tianyou proposed the "four-step waist type." Professor Feng Wei proposed the objective quantification of three-dimensional scoliosis angle "four-step waist type."OBJECTIVE:To explore the application value of three-dimensional scoliosis angle in evaluating the efficacy of Feng's spinal manipulation in the treatment of patients with lumbar disc herniation.METHODS:A total of 149 hospitalized patients with lumbar disc herniation were enrolled sequentially,including 96 cases of type-Ⅰ/Ⅱ and 55 cases of type-Ⅲ/Ⅳ. The patients were treated with manual therapy for 2 weeks,and 10 healthy volunteers were included as healthy controls. The three-dimensional scoliosis angle was measured using surface topography technology. The difference of three scoliosis angles between patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ was compared before and after treatment. The difference between patients after treatment and healthy subjects was compered. The difference of three-dimensional scoliosis angles between type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ after treatment was compared. The intrinsic correlation of each projection plane of three-dimensional scoliosis angle and its correlation with commonly used clinical efficacy scores were explored.RESULTS AND CONCLUSION:(1) The three-dimensional scoliosis angle was significantly different in patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ before and after treatment (P<0.05). (2) There were significant differences in coronal curve angle and transverse curve angle between patients with type-Ⅰ/Ⅱ,type-Ⅲ/Ⅳ and healthy subjects (P<0.05),but there was no significant difference in sagittal curve angle (P>0.05). (3) There was a correlation between the angles of each section of the three-dimensional angle,and there was a correlation between the three-dimensional angle and the subjective scale. (4) It is indicated that the three-dimensional scoliosis angle can quantitatively evaluate the changes of body deformity before and after treatment. Quantitative indicators can reveal the changes in the patient's condition before and after treatment. The three-dimensional scoliosis angle can reflect the severity of the impact on the patient's living conditions,but the evaluation of scoliosis by a single plane parameter has certain limitations.

Objective:To investigate the role and molecular mechanisms of transcription factor EB (TFEB) and its target genes in the treatment of multiple myeloma (MM) with bortezomib.Methods:TFEB target genes were predicted using the GTRD database (http://gtrd.biouml.org/), identifying Ptch1 gene for further study. Expression changes of Ptch1 in RPMI8226 and U266 MM cell lines after bortezomib treatment were assessed by real time fluorogenic quantitative PCR (RT-qPCR) and Western blot. RPMI8226 and U266 cell lines were transfected with siRNA-TFEB, and mRNA and protein levels of key factors (Ptch1, Gli1) in the Ptch1/Hedgehog signaling pathway were measured by RT-qPCR and Western blot. Furthermore, Ptch1 was overexpressed in MM cell lines via lentiviral transduction. Autophagy was evaluated by acridine orange staining, and protein levels of LC3B, Beclin-1, and Lamp-1 were measured by Western blot. Lysosomal quantity changes were assessed by lysosomal fluorescent probes.Results:Bortezomib (6.0×10 -6 mmol/L, 24 h) significantly reduced Ptch1 mRNA and protein levels in both cell lines compared with blank control group (all P<0.05). siRNA-TFEB transfection reversed bortezomib’s inhibition of Hedgehog pathway key factors Ptch1 and Gli. Ptch1 overexpression in bortezomib-treated RPMI8226 and U266 cells significantly reduced the relative expression of autophagy-related proteins LC3B, Beclin-1, and Lamp-1 (all P=0.001). Acridine orange staining showed fewer acidic vesicular organelles within two cell lines (all P=0.001). The relative fluorescence expressions of lysosomal probes reflecting the number of lysosomes were also decreased ( P values of RPMI8226 and U266 cell lines were 0.001 and 0.007, respectively) . Conclusion:The knockdown of TFEB can specifically promote the expression of the Ptch1/Hedgehog signaling pathway, thereby reducing bortezomib-induced autophagy in MM cells and reversing the inhibitory effect of bortezomib on the proliferation of MM cell lines.

A 54-year-old male patient with severe acute respiratory distress syndrome caused by inhalation injury was admitted to the First People's Hospital of Lianyungang City on June 26 th, 2022. After admission, the patient received invasive mechanical ventilation (driving pressure-guided ventilator parameter setting) combined with prone position treatment immediately, but his condition continued to deteriorate. Five hours after admission, the patient received veno-venous extracorporeal membrane oxygenation (VV-ECMO) supporting treatment, treatment based on ultra-protective lung ventilation strategy combined with prone position ventilation for more than 12 hours per day. At the same time, pulse contour cardiac output monitoring technology was used to monitor cardiac index and extravascular lung water index to guide volume management, and fiberoptic bronchoalveolar lavage was performed for several times. After that, the patient was successfully weaned from VV-ECMO and ventilator, and then discharged from hospital successfully. During follow-up of one year after the injury, the patient showed no obvious respiratory symptoms, and his lung function was basically normal.
