Based on the concept of "regulating the five zang organs and harmonizing the spleen and stomach"， globus hystericus is believed to originate from dysfunction of the five zang organs and disharmony of the spleen and stomach. Treatment primarily focuses on regulating the spleen and stomach while also considering other affected organs， with a self-prescribed Anpiwei Jingyan Formula （安脾胃经验方） for harmonizing the spleen and stomach as the foundational treatment. Additionally， syndrome-based modifications are applied according to imbalances in the heart， lung， kidney， or liver. For heart-yang deficiency， modified Linggui Zhugan Decoction （苓桂术甘汤） could be combined； for heart-yin deficiency， modified Tianwang Buxin Pill （天王补心丹） could be combined. For lung failing to disperse and descend and fluid retention， modified Sanao Decoction （三拗汤） could be combined； for lung and stomach yin deficiency， modified Shashen Maidong Decoction （沙参麦冬汤） could be combined. For kidney-yang deficiency with ascending counterflow of cold water， modified Jingui Shensi Pill （金匮肾气丸） could be combined； for kidney-yin deficiency， modified Liuwei Dihuang Pill （六味地黄丸） could be combined. For liver constraint and spleen deficiency， modified Sini Powder （四逆散） could be combined； for liver-yin deficiency or liver stagnation transforming into fire and attacking the stomach， modified Yiguan Decoction （一贯煎） could be combined.

Innate lymphoid cells are an important part of innate mucosal immunity and participate in immune response by secreting effector cytokines and regulating the functions of other immune cells.They are similar to T helper cells in transcription factors and secretory cytokines,but they also have some unique functions.Different innate lymphocyte subsets play different roles in chronic obstructive pulmonary disease(COPD)according to their respective characteristics.Compared with adaptive lymphocyte,innate lymphocyte is relatively less in lymphoid tissue,accounting for only a small part of lung immune cells,but these lymphocyte cells play a crucial role in the development and progression of COPD.In this paper,the role of innate lymphoid cells in COPD and the related research progress were reviewed.

Objective:To explore the effect of 3D printing extravascular stent implantation on the hemodynamics of the relevant large vessels in patients with nutcracker syndrome（NCS），and to discuss the clinical safety of this new procedure.Methods:A total of 30 NCS patients admitted to Tangdu Hospital Affiliated to Air Force Military Medical University from May to December 2023 were prospectively included. All the patients were received laparoscopic 3D printing extravascular stent implantation for NCS treatment. Whether the lumbago，abdominal pain，hematuria，proteinuria and varicocele had improved after the stent implantation were observed. The inner diameter，blood flow velocity of left renal vein，abdominal aorta，superior mesenteric artery and the diameter of inferior vena cava were measured by ultrasound 1 day before surgery and 8 days after surgery，respectively.In addition，the carotid-femoral pulse wave velocity（cfPWV）was measured by a newly developed method，by which the arterial stiffness could be detected based on Doppler ultrasound. The blood flow Doppler spectra of each subject were recorded at the right common carotid artery and the right common femoral artery，respectively，then based on that，the cfPWV was automatically calculated by this new technique. The above internal diameters，blood flow velocity and cfPWV were compared before and after the laparoscopic 3D printing extravascular stent implantation.Results:Among the 30 patients，the postoperative blood flow velocity at the left renal vein compression site was significantly lower than that before surgery［（50.7 ± 14.8）cm/s vs（122.1 ± 24.1）cm/s， P<0.001）］，and the clinical symptoms，including lumbago and abdominal pain，hematuria，proteinuria and varicocele were significantly improved（all P<0.05）. There were no significant changes in the internal diameter，blood flow velocity of abdominal aorta，superior mesenteric artery and the diameter of inferior vena cava，and cfPWV before and after operation（all P>0.05）. Conclusions:The 3D printing extravascular stent implantation through laparoscope can effectively improve left renal vein compression in patients with NCS，and cause no significant change in large arterial hemodynamics，suggesting that this surgical method is a safe and reliable treatment for patients with NCS.

Objective To evaluate the clinical efficacy of hip-knee-ankle active and passive exercise therapy in patients with early-to mid-stage knee osteoarthritis(KOA).Methods A total of 180 patients with early to mid-stage knee osteoarthritis(KOA)were recruited from the First Affiliated Hospital of Hebei University of Tradi-tional Chinese Medicine between March 2023 and March 2024.Patients were randomly assigned to one of four groups:active movement group,passive movement group,combined movement group,and control group,with 45 patients in each group.The active movement group received hip-knee-ankle active movement therapy daily until the end of follow-up.The passive movement group underwent hip-knee-ankle passive movement therapy three times per week for two weeks.The combined movement group received both active and passive therapies.The control group was administered oral celecoxib capsules(200 mg once daily for two weeks).Joint function was assessed in all four groups before treatment,at two weeks post-treatment,and at 14 weeks post-treatment.The primary outcome measure was the WOMAC joint function score,while secondary outcomes included the WOMAC pain score,stiffness score,and quality of life score(SF-12).Results A total of 160 patients completed the trial,with 39 in the active group,42 in the passive group,40 in the combined group,and 39 in the control group.There were no significant differences in baseline characteristics among the groups(P>0.05).Compared to baseline,the WOMAC scores for function,pain,and stiffness in the passive,combined,and control groups decreased significantly at both 2 and 14 weeks post-treatment(P<0.05),while the SF-12 scores increased significantly(P<0.05).Between 2 and 14 weeks post-treat-ment,the active and combined groups showed further significant decreases in WOMAC function,pain,and stiffness scores(P<0.05)and increases in SF-12 scores(P<0.05).At 2 weeks post-treatment,compared to the control group,the passive and combined groups exhibited significantly lower WOMAC function scores(P<0.05),with no significant difference between the passive and combined groups(P>0.05).By 14 weeks post-treatment,the active and combined groups demonstrated significantly lower WOMAC function scores(P<0.05),with the combined group showing a significantly lower score than the active group(P<0.05).Conclusion The four therapeutic approaches demonstrate a certain degree of efficacy in improving joint function for patients with early and mid-stage KOA.The passive therapy group exhibits superior short-term outcomes,while the active therapy group shows better long-term benefits.The combined therapy group presents notable advantages in both short-term and long-term effi-cacy,although its short-term effectiveness does not surpass that of the passive therapy group.It is recommended for patients with early and mid-stage KOA who have underlying gastrointestinal and cardiovascular conditions.

Objective:To explore the latent classes of fatigue trajectories and influencing factors in elderly patients with chronic pneumonia.Methods:A convenience sampling method was used to select 188 elderly patients with chronic pneumonia admitted to the Department of Geriatrics at Zhejiang Provincial Tongde Hospital from January 2023 to January 2024. General Data Questionnaires, Nutrition Risk Screening 2002, Athens Insomnia Scale, Hamilton Anxiety Scale, Community Commitment Scale, and Fatigue Scale were used to assess the patients. Patients were followed up for fatigue Scale at the time of consultation (T0) , and at the third (T1) and sixth (T2) months after consultation. Latent class growth analysis was used to model the trajectory of fatigue changes in elderly patients with chronic pneumonia.Results:A total of 188 questionnaires were distributed, with 165 valid responses, yielding an effective response rate of 87.8% (165/188) . The Fatigue Scale scores at T0, T1, and T2 were (4.63±1.74) , (5.54±1.90) , and (7.82±2.84) , respectively. The fatigue trajectories could be classified into three latent classes: low fatigue-slow increase group (74.5%, 123/165) , low fatigue-worsening group (10.3%, 17/165) , and high fatigue-slow increase group (15.2%, 25/165) . Multivariate logistic regression analysis showed that age, smoking index, number of chronic diseases, sleep, anxiety, and duration of cough and sputum were significant influencing factors for the fatigue trajectory in elderly patients with chronic pneumonia ( P<0.05) . Conclusions:Fatigue trajectories in elderly patients with chronic pneumonia exhibit group heterogeneity. Healthcare providers should develop targeted nursing measures based on different trajectory classes to alleviate fatigue and improve quality of life.

Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.

The adenosine 5'-triphosphate (ATP)-binding cassette (ABC) transporter, IrtAB, plays a vital role in the replication and viability of Mycobacterium tuberculosis (Mtb), where its function is to import iron-loaded siderophores. Unusually, it adopts the canonical type IV exporter fold. Herein, we report the structure of unliganded Mtb IrtAB and its structure in complex with ATP, ADP, or ATP analogue (AMP-PNP) at resolutions ranging from 2.8 to 3.5 Å. The structure of IrtAB bound ATP-Mg2+ shows a "head-to-tail" dimer of nucleotide-binding domains (NBDs), a closed amphipathic cavity within the transmembrane domains (TMDs), and a metal ion liganded to three histidine residues of IrtA in the cavity. Cryo-electron microscopy (Cryo-EM) structures and ATP hydrolysis assays show that the NBD of IrtA has a higher affinity for nucleotides and increased ATPase activity compared with IrtB. Moreover, the metal ion located in the TM region of IrtA is critical for the stabilization of the conformation of IrtAB during the transport cycle. This study provides a structural basis to explain the ATP-driven conformational changes that occur in IrtAB.
