To summarize the clinical experience of treating idiopathic olfactory disorder from the perspective of heart and lungs. It is believed that the sense of olfaction is based on the nose， rooted in the heart， functioning through the lungs， and conveyed by pectoral qi. The key pathogenesis of idiopathic olfactory disorder lies in the accumulation of pathogenic factors in the heart and lungs， blood vessel obstruction， the failure of the lungs to disperse and descend， and the loss of control of pectoral qi. In treatment， internal and external therapies could be combined. The internal therapy can correct the imbalance of the zang-fu organs， using the self-prescribed Bilong Formula （鼻聋方） to dispel wind and diffuse the lung， invigorate blood and relieving stuffy orifices； the external therapy can clear nasal obstruction， supplemented by intradermal needle embedding at three acupoints， bilateral Yingxiang （LI 20）， bilateral Shangyingxiang （EX-HN 8） and Yintang （GV 29）， and integrated olfactory training for comprehensive treatment.

Objective To explore the efficacy of precise surface positioning method in percutaneous screw fixation for Jones fracture.Methods Data of 46 patients with Jones fractures admitted to our hospital from September 2021 to December 2023 were retrospectively analyzed.According to the different treatment methods,the patients were divided into screw groups(24 patients fixed by percutaneous screws)and tension band groups(22 patients fixed by incision and reset tension band).The general conditions,follow-up time,surgical time,hospitalization time,fracture reduction quality,postoperative complete weight-bearing time,fracture healing time,and complications in the two groups were recorded and compared.The American Association of Foot and Ankle Surgery(AOFAS)system was used to assess the recovery of foot function.Results There was no statistically significant difference in the general data before the operation between the two groups of patients(P＞0.05).The follow-up time of the two groups was 6 to 24 months.Compared with the tension band group,the screw group had shorter operation time[(32.96±5.35)min vs.(47.27±9.42)min],shorter hospitalization time[(5.75±1.18)d vs.(7.68±2.05)d],earlier postoperative complete weight-bearing time[(6.47±0.73)w vs.(7.29±1.66)w],faster fracture healing time[(3.31±0.68)months vs.(4.29±1.29)months],higher AOFAS score[(89.13±2.62)vs.(79.59±4.49)](all P＜0.05).The tension band group of fracture reduction quality was better than the screw group(P＜0.05).The quality of fracture reduction during the operation in the tension band group was better than that in the screw group(P＜0.05).In terms of complications:no complications occurred in the screw group,one patient in the tension band group developed infection,and one patient had a loose Kirchner needle.Conclusion Precise surface positioning method in percutaneous screw fixation for Jones fracture is a safe and effective method with precise positioning,simple operation,small trauma,and rapid rehabilitation,which is worthy of clinical promotion,but the indications need to be strictly controlled according to the type of fracture.

Objective:To explore clinical characteristics of multiple sclerosis(MS)patients in Suzhou,and to analyze main factors affecting their prognosis.Methods:General data,clinical symptoms,cerebrospinal fluid and imaging examinations of 51 MS patients admitted to Department of Neurology of the Second Hospital of Soochow University from July 31,2009 to July 31,2021 were retrospectively analyzed,and main factors affecting their prognosis were discussed.Results:Average age of onset of 51 MS patients was(43.3±15.6)years old,female accounted for 56.9%,male/female=1/1.3.Adult onset MS(AOMS)accounted for 62.8%,male/female=1/1.7;late onset MS(LOMS)accounted for 37.2%,male/female=1/0.9.Relapsing remitting MS(RRMS)accounted for 76.5%,and chronic onset accounted for 60.8%.Average annual recurrence rate was 8.8%.The first symptoms were numbness and weakness of limbs.Dizziness and numbness were more common in patients without recurrence after diagnosis of MS,and limb weak-ness and numbness were more common in patients with recurrence.Among lesions of MRI,62.7%(32/51)of periventricular involve-ment,52.9%(27/51)of spinal cord involvement,51.0%(26/51)of infratentorial involvement.Proportion of subtentorial and spinal cord(cervical,thoracic)involved were significantly higher in patients with recurrent MS than without recurrence.Values of albumin,IgG,IgA and IgM in cerebrospinal fluid increased with increase of recurrence times.EDSS score of male was higher than female,and LOMS score was higher than AOMS.MS patients without relapse had a low EDSS score,and median EDSS score at current follow-up was 0(0,1.00)score.MS score with relapse was relatively high,and median EDSS score at current follow-up was 2.75(0.25,7.25)score.Conclusion:MS patients with chronic onset are more common,with a high proportion of LOMS,and proportion of males increases with increasing age of onset.High EDSS score at first onset,cervical,thoracic and subtentorial lesions,increased values of cerebrospinal fluid albumin,IgG,IgA,IgM,age at first onset(50+years old),male associate with poor MS prognosis.

Objective To evaluate the safety and therapeutic efficacy of three-dimensional(3D)-printed personalized cervical correction pillows for treating cervical spondylotic radiculopathy.Methods A finite element model was established to simulate and analyze the biomechanical changes in cervical spine before and after using the pillow.Additionally,20 patients with chronic neck pain were included to analyze changes in visual analogue scale(VAS)scores,neck disability index(NDI),pressure pain threshold(PPT),Borden value,cervical lordosis,T1 slope,cervical slope,and thoracic inlet angle before and after using the pillow.Results Finite element analysis indicated that the maximum stress on vertebral bodies increased by 64.35％and the maximum stress on cartilage tissues by 5.09％after using the pillow.The Borden value improved by 45.75％.Clinical studies showed a significant reduction in VAS scores,NDI,and PPT after treatment(P＜0.05),while PPT,Borden value,cervical lordosis,T1 slope,and thoracic inlet angle significantly increased(P＜0.05).Conclusions The 3D-printed personalized cervical correction pillow is safe and effective in alleviating neck pain and improving cervical curvature,and it provides a new and effective non-surgical treatment option for cervical spondylotic radiculopathy,with significant clinical implications.

OBJECTIVE To explore the potential mechanism of Yiqi Wenyang Recipe in the intervention of allergic rhinitis(AR)mice.METHODS C57/BL6 mice were randomly divided into blank,model,Yiqi Wenyang Recipe and Yiqi Wenyang Recipe+EX-527[Sirtuin 1(SIRT1)inhibitor]groups.The AR model of mice was established by ovalbumin based challenge sensitization method,each group received corresponding intervention measures.Assessment of behavioral changes in mice;nasal mucosal lesions were observed by HE and toluidine blue staining;the serum levels of interleukin-4(IL-4),interferon-γ(IFN-γ),and immunoglobulin E(IgE)were measured by ELISA;the expression levels of phospho-Janus kinase 2(p-JAK2),phospho-signal transducer and activator of transcription 6(p-STAT6),phospho-dynamin-related protein 1(p-Drp1),SIRT1,peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC-1α)in nasal mucosa were determined by Western blot combined with immunofluorescence;reactive oxygen species(ROS)levels were detected by fluorescent probe method;the morphological changes of mitochondria in the microstructure of na-sal mucosa were observed by transmission electron microscopy.RESULTS Compared with the blank group,the frequency of scratch-ing and sneezing in the model group was significantly increased,and a large number of eosinophils and mast cells were found in the na-sal mucosa(P<0.05);compared with the model group,the nasal allergic symptoms and the level of nasal mucosal inflammatory reaction in the Yiqi Wenyang Recipe group were significantly improved(P<0.05);compared with the Yiqi Wenyang Recipe group,the scratch-ing and sneezing of mice in the Yiqi Wenyang Recipe+EX-527 group increased again,and the counts of eosinophils and mast cells in nasal mucosa increased significantly(P<0.05).Compared with the model group,the levels of serum IL-4 and IgE in the Yiqi Wenyang Recipe group decreased,while the level of serum IFN-γ increased(P<0.05);the serum IL-4 and IgE of mice in the Yiqi Wenyang Recipe+ex-527 group were significantly higher than those in the Yiqi Wenyang Recipe group(P<0.05).Western blot and immunofluo-rescence showed that Yiqi Wenyang Recipe could effectively inhibit the increase of p-JAK2,p-STAT6,p-Drp1(ser616)levels induced by ovalbumin sensitization,as well as the decrease of SIRT1 and PGC-1 α expression(P<0.01);however,the intervention of EX-527 significantly blunted the regulatory effect of Yiqi Wenyang Recipe on the above signaling molecules(P<0.05,P<0.01).The results of transmission electron microscopy and fluorescent probe showed that in the model group,a large number of spherical mitochondria were found in the mitochondria of nasal mucosa,and the level of ROS was significantly increased(P<0.01);;the intervention of Yiqi We-nyang recipe effectively restored the long tubular morphology of mitochondria and reduced ROS level(P<0.01);,while the intervention of EX-527 weakened the above improvement effect(P<0.01).CONCLUSION Yiqi Wenyang Recipe can regulate SIRT1 to activate PGC-1α,and then inhibit Drp1 mediated excessive mitochondrial fission to intervene AR;SIRT1 may be one of the important targets of Yiqi Wenyang Recipe in the intervention of AR.

OBJECTIVE To investigate the effects of the split formulas of Biyuan Heji(BYHJ)on paranasal sinus mucosal in-flammation in rats with acute rhinosinusitis(ARS)based on the pathogenesis of"wind-cold transforming into lung-heat".METHODS Unilateral nasal cavity occlusion combined with nasal dripping of Staphylococcus aureus were performed to establish a rat model of ARS.SD rats were randomly divided into blank,model,BYHJ(wind-cold removal+lung-heat removal),lung-heat removal,wind-cold removal,and positive drug groups,with 6 rats in each group.The rats were treated with the corresponding drugs for 7 d and then the samples were collected.HE staining was used to observe the pathological changes of rat paranasal sinus mucosa tissues,ELISA was employed to determine the levels of interleukin-1β(IL-1β),IL-6,IL-8,IL-9,IL-10,and IL-12 in serum,immunohistochemis-try(IHC)was adopted to measure the protein expression of tumor necrosis factor-α(TNF-α)and intercellular adhesion molecule(ICAM-1)in paranasal sinus mucosa tissues,and Western blot was used to detect the protein expression of phosphorylated p38 mito-gen-activated protein kinase(p38 MAPK),nuclear transcription factor-κB p50(NF-κB p50),and NF-κB p65 in paranasal sinus mucosa tissues.RESULTS The acute sinusitis rat inflammation model was successfully established.Compared with the model group,the water drinking,diet eating,and body weight of rats in the BYHJ group,wind-cold removal,lung-heat removal,and positive drug groups were significantly improved,the aggregation of inflammatory cells in the paranasal sinus mucosal tissue was reduced,and the levels of IL-1β,IL-6,IL-8,IL-9,and IL-12 in the serum were significantly reduced(P<0.01),IL-10 content significantly in-creased(P<0.01),the protein expression of TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 in the paranasal sinus mucosa was significantly decreased(P<0.01).The comparison between various traditional Chinese medicine groups showed that the decrease of IL-1β,IL-6,IL-8,IL-9,IL-12,TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 and the increase of IL-10 in the BYHJ group were better than those in the split formula groups(P<0.01),and the lung-heat removal group was better than the wind-cold removal group(P<0.01).CONCLUSION BYHJ and its split formulas can effectively inhibit the inflammatory response in rats with ARS.
