RESUMO
Previous studies show that glycogen synthase kinase 3β (GSK3B) plays an important role in tumorigenesis. However, its role in cervical cancer is unclear. The present study silenced GSK3B with siRNAs and/or chemical inhibitors to determine its role in HeLa cervical cancer cell proliferation and migration as well as in xenograft tumor growth. Cell Counting Kit (CCK)-8 and 5-ethynyl-2'-deoxyuridine (EdU) assays were used to determine cell survival and proliferation. Scratch and Transwell® assays were used to evaluate cell migration. Xenograft tumors were used to evaluate the effect of GSK3B on tumor growth. Transcriptomic sequencing was used to clarify the mechanisms underlying the foregoing processes. Public databases and clinical specimens showed that GSK3B was upregulated in cervical cancer tissues and correlated with poor prognosis. In vitro experiments indicated that GSK3B inhibition reduced cell viability, proliferation, and migration. In vivo experiments demonstrated that GSK3B inhibition slowed xenograft tumor growth. Transcriptomic sequencing revealed that GSK3B inhibition modulated the phosphatidylinositol 3-carboxykinase (PI3K)/protein kinase B (Akt) and extracellular matrix (ECM)-receptor interaction signaling pathways. GSK3B inhibition decreased the protein levels of phosphorylated PI3K and Akt and the levels of mesenchymal markers but increased those of epithelial markers. An activator of the PI3K/Akt signaling pathway counteracted the suppressive effects of GSK3B inhibition on HeLa cell viability and proliferation and on PI3K/Akt signaling. Our data suggested that GSK3B regulated cervical cancer cell proliferation and migration by modulating the PI3K/Akt signaling pathway and epithelial-to-mesenchymal transition (EMT).
RESUMO
Objective:To discuss the clinical characteristics,diagnosis processes,and treatment methods of one patient with congenital intrabdominal hernia,and to summarize the potential misconceptions during the diagnostic and treatment processes,and to improve the clinicians'awareness of this disease.Methods:The clinical data and auxiliary examination results of one patient with congenital intrabdominal hernia were collected and analyzed,and the related literatures were reviewed.Results:The patient,a 65-year-old male,sought care at the local hospital due to upper abdominal pain before 2 d;there were no significant abnormalities in the examination results at the cocal hospital;blood glucose>25 mmol·L-1.After receiving hypoglycemic,rehydration,and blood purification treatment,the condition of the patient was worsened,presenting with confusion,hypotension,and respiratory distress;the patient admitted in our hospital for further diagnosis and treatment.After admission,the patient was given despite fluid resuscitation,mechanical ventilation,and supportive treatment,but there was no improvement in the symptoms;interventional radiology was performed angiography of the abdominal artery and right femoral vein,which showed no significant vascular abnormalities in the abdomen.An abdominal paracentesis yielded a mixed bloody fluid,suggesting the concealed intraperitoneal disease;exploratory laparotomy was performed.During operation,the intrabdominal hernia with small intestine necrosis and septic shock were diagnosed,and partial small intestine resection,anastomosis,adhesiolysis,and abdominal irrigation and drainage were carried out.The patient had a good recovery and was discharged on the 14th day after operation.Conclusion:Congenital intrabdominal hernia is a very rare cause of intestinal obstruction in the adults,and high suspicion for intrabdominal hernia is one of the differential diagnosis for atypical acute abdomen;early multidisciplinary intervention can be lifesaving for the patients.
RESUMO
Objective:To predict the mechanism of Panacis Quinquefolii Radix- Acori Tatarinowii Rhizoma (PQ-AT) in the treatment of diabetes encephalopathy (DE) using network pharmacology combined with molecular docking; To conduct experimental verification.Methods:The active components and targets of PQ and AT were screened by TCMSP database. The GeneCards and Disgenet were used to collect DE related target genes. String database and Cytoscape software were used to structure PPI network and perform visualization analysis. The common targets were imported into Metascape platform for GO annotation and KEGG enrichment analysis. Molecular docking was used to verify the binding ability of active components to core targets. Rats were randomly divided into a blank group, a model group, and a low-dose group of PQ-AT (1.08 g/kg), a high-dose group of PQ-AT (2.16 g/kg), and a metformin group (0.18 g/kg) using a random number table. To establish the rat model of diabetes encephalopathy, intraperitoneal injection of streptozotocin was used in addition to the blank group. After a 12-week drug intervention, TNF-α and Cyclooxygenase-2 (PTGS2) protein expression in the cerebral cortex of rats was detected using Western blot.Results:A total of 26 active components in PQ-AT and 107 related targets of DE were obtained, mainly including TNF, JUN, and PTSG2, which were mainly concentrated in TNF signaling pathway, cancer and other signal pathways. Molecular docking showed that the main active components of PQ-AT had relatively stable binding activity with TNF-α and PTGS2. Western blot results shows that compared with the model group, the expressions of PTGS2 and TNF-α significantly decreased in each administration group ( P<0.05 or P<0.01). Conclusion:PQ-AT can act on TNF, CASP3, JUN, STAT3, PTGS2 and other core targets to regulate signal pathways such as TNF, and inhibit inflammatory reaction to achieve the effect of treating DE.
RESUMO
Korean government first proposed the internationalization of the Korean medicine strategy in 2003. During this time, the Ministry of Health and Welfare enacted a series of policies to support the internationalization of Korean medicine, which has led to fruitful results in attracting foreign patients, international education, and international research cooperation. At the same time, Korean medicinal materials, functional foods, and cosmetics have also entered overseas markets, reaping substantial economic benefits. As Chinese and Korean traditional medicines have the same origin and different flows, the experience of the international development of Korean medicine can provide a reference for the development of the internationalization of TCM to a certain extent.
RESUMO
In recent years,with the continuous innovation of modern war mode,weapons and protective equipment,the mechanism and mode of war trauma have also produced great changes.The widespread use of bulletproof vest and improvised explosive devices has led to increasing incidence of genitourinary trauma.The pattern of genitourinary trauma has also transformed from internal structures(kidney,ureters,bladder)to external structures(scrotum,testes,penis,urethra),suggesting that the research focus of genitourinary system war trauma should be gradually transformed to trauma research of lower urinary tract and external genitalia.This article reviews the incidence,treatment and prognosis of genitourinary trauma in several modern wars,and mainly describes the relevant conditions of lower urinary tract and external genitalia trauma and the relevant progress in the treatment in recent years.
RESUMO
Unilateral biportal endoscopic(UBE)technique is a minimally invasive spinal technique developed rapidly in recent years.Compared with traditional spinal endoscopy,the prominent feature of UBE is that it can open two channels on the same side of the spine,which can be used to provide visual field and insert operating instruments respectively,greatly expanding the operating space and reducing the difficulty of surgery.It has the advantages of less bleeding,little injury,quick recovery and mild pain,and has unique advantages in the treatment of lumbar spinal stenosis,lumbar disc herniation and other lumbar degenerative diseases.With the continuous in-depth exploration and development of the UBE technique,the field of diseases that can be treated by this technology has gradually expanded.It is not only limited to lumbar diseases,but also has made great progress in cervical and thoracic diseases,which has attracted the attention of many spinal surgeons.UBE technique has become one of the promising surgical methods for spinal-related diseases,but there are also complications such as incomplete decompression,nerve root and dural injury,epidural hematoma,relatively prolonged operation time,operation fatigue and other deficiencies.This paper summarizes the progress of the UBE technique,discusses its complications and deficiencies,proposes relevant solutions and possible future directions for its development,so as to provide reference for the clinical practice of UBE technique.

RESUMO
BACKGROUND:Previous brain studies have mostly focused on adults and fetuses,and the developmental characteristics of young children's brainstems have rarely been studied. OBJECTIVE:To observe the brainstem development characteristics of healthy young children and to explore the age-related differences and their correlation with sex. METHODS:From January 2019 to April 2022,a retrospective study of 3.0T MRI images of 174 children aged 2 to 6 years in the Affiliated Hospital of Inner Mongolia Medical University was conducted,and the median sagittal diameter,area and angle of the brainstem(including midbrain,pons and medulla oblongata)were measured. RESULTS AND CONCLUSION:There is an age-related increase in the anterior and posterior diameters of the midbrain,pons and medulla oblongata in the 2-5 years old group as well as in the longitudinal diameter and area of the midbrain,pons and medulla oblongata in the 2-6 years old group.Except for the longitudinal diameter of the medulla oblongata,all others show a positive correlation with age(r>0,P<0.05).In the 2-3 years old group and 4-5 years old group,the children are in the rapid growth and development stage,and these two age groups can be used as the key observation indicators for the development of young children.The anterior-posterior diameter,longitudinal diameter,area of the pons and total brainstem area are strongly correlated with age,which can be used as the key observation indicators for the brainstem development in young children.
RESUMO
BACKGROUND:The lower cervical vertebral pedicle is the main stress site of the posterior column of the spine,which is of great significance for the maintenance of the stability of the human center of gravity and the reduction of shock.At present,there are few reports on the characteristics of the internal bone trabeculae,and the characteristics of the joint site of the vertebral pedicle with the articular process and the vertebral body.It is urgent to understand the fine anatomical structure of the vertebral pedicle and the relationship and function of each part. OBJECTIVE:To observe the microanatomical morphology of the vertebral pedicle by Micro-CT scanning of cervical vertebra specimens,and to measure and analyze the microstructure and morphometric parameters of the bone trabecula in the cervical pedicle under normal conditions to evaluate the safety performance of the cervical spine. METHODS:Micro-CT scanning was performed on 31 sets of cervical vertebrae C3-C7.By checking and reconstructing the areas of interest in the bone trabecular within the vertebral pedicle,the morphological characteristics and distribution direction of the bone trabecular within the cervical pedicle were observed,and the bone microstructure parameters were detected,and the differences in the bone microstructure of the C3-C7 vertebral pedicle were analyzed and compared. RESULTS AND CONCLUSION:(1)The Micro-CT images showed that the honeycomb bone trabeculae of the pedicle of the lower cervical spine presented a complex network of microstructures.The trabeculae near the cortical bone were lamellar and relatively compact,extending forward toward the vertebral body and backward toward the articular process lamina.Abatoid bone trabeculae extended into the medullary cavity and transformed into a network structure,and then into rod-shaped bone trabeculae.The rod-shaped bone trabeculae were sparsely distributed in the medullary cavity.(2)Statistical results of morphological parameters of bone trabeculae showed that bone volume fraction values in C4 and C5 were higher than that in C7(P＜0.05).The bone surface/bone volume value in C7 was higher than that in C3,C4 and C6(P＜0.05).The bone surface density of bone trabeculae in C7 was higher than that in C3,C4,C5 and C6(P＜0.05).Trabecular thickness in C7 was higher than that in C3,C4 and C5(P＜0.05).Bone surface/bone volume and bone surface density of the left pedicle bone trabecular were greater than those on the right side(P＜0.05).(3)The microstructural changes of C3-C7 were summarized,in which the load capacity and stress of the C7 pedicle were poor,and the risk of injury was high in this area.
RESUMO
Objective:To investigate the anatomic classification and reconstruction of right intrahepatic bile duct in the donor liver of split liver transplantation (SLT).Methods:The retrospective and descriptive study was constructed. The clinical data of 85 patients who underwent SLT in the Third Affiliated Hospital of Sun Yat-sen University from July 2014 to January 2022 were collected. There were 65 males and 20 females, aged 45(range, 1-82)years. Observation indicators: (1) surgical conditions; (2) anatomy of right intrahepatic bile duct; (3) bile duct reconstruction; (4) postoperative biliary complications; (5) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3).Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical conditions. Of the 85 donor livers, 11 donor livers were split between the left and right hemilivers, and 74 donor livers were split between the classic right trilobe and left lateral lobe. The cold ischemia time of 85 donor livers was 291(273, 354)minutes, and the operation time, anhepatic phase time and volume of intraoperative blood transfusion of 85 recipients were (497±97)minutes, 51(40, 80)minutes and 8(7, 12)U. (2) Anatomy of right intrahepatic bile duct. Of the 85 donor livers, there were 47 donor livers with classic bile duct anatomical model (type 1), of the ratio as 55.3%(47/85), and 38 donor livers with anatomical variants, of the ratio as 44.7%(38/85). Of the 38 donor livers with anatomical variants, 7 donor livers were type 2, 16 donor livers were type 3a, 2 donor livers were type 3b, 2 donor livers were type 3c, 1 donor liver was type 4, 3 donor livers were type 5a, 4 donor livers were type 5b, 3 donor livers were type 6. For bile duct splitting patterns of the 85 donor livers, 84 donor livers were split with the main trunk of common hepatic duct preserving in the right hemiliver or right trilobe, and 1 donor liver were treated with complete left and right hemiliver splitting to preserve the main trunk of the common hepatic duct in the left hemiliver and the right hemiliver in the right hepatic duct (type 1 bile duct anatomical model). There were 84 donor livers with only one bile duct opening, and 1 donor liver with two bile duct openings (type 3c bile duct anatomical model). (3) Bile duct reconstruction. Of the 85 recipients, there were 69 recipients with common bile duct end-to-end anastomosis to common bile duct of donor liver (38 donor livers with type 1 bile duct anatomical model, 5 donor livers with type 2 bile duct anatomical model, 14 donor livers with type 3a bile duct anatomical model, 2 donor livers with type 3b bile duct anatomical model, 1 donor liver with type 4 bile duct anatomical model, 3 donor livers with type 5a bile duct anatomical model, 4 donor livers with type 5b bile duct anatomical model, 2 donor livers with type 6 bile duct anatomical model), 11 recipients with jejunum anastomosis to common bile duct of donor liver (7 donor livers with type 1 bile duct anatomical model, 2 donor livers with type 2 bile duct anatomical model, 1 donor liver with type 3c bile duct anatomical model, 1 donor liver with type 6 bile duct anatomical model), 3 recipients with jejunum anastomosis to common hepatic duct of donor liver (1 donor liver with type 1 bile duct anatomical model, 2 donor livers with type 3a bile duct anatomical model), 1 recipient with jejunum anastomosis to right hepatic duct of donor liver (type 1 bile duct anatomical model), 1 recipient with common hepatic duct end-to-end anastomosis to right posterior branch of donor liver combined with jejunum of the recipient Roux-en-y anastomosis to common hepatic duct of donor liver (type 3c bile duct anatomical model). (4) Postoperative biliary complications. Of the 85 recipients, 6 cases had postoperative biliary complications, with an incidence of 7.1% (6/85). Of the 6 recipients with postoperative biliary complications, there were 5 recipients with donor liver with type 1 bile duct anatomical model, including 3 cases undergoing postoperative biliary stricture with biliary leakage and 2 cases undergoing postoperative biliary anastomotic stricture, 1 recipient with donor liver with type 3b bile duct anatomical model and undergoing postoperative biliary anastomotic stricture and bile leakage in the liver section. Cases with biliary complications were 5 in the 47 recipients with donor liver with classic bile duct anatomical model and 1 in the 38 recipients with donor liver with anato-mical variants, showing no significant difference between them ( P>0.05). (5) Follow-up. There were 83 recipients receiving followed up for 52(12,96)months. During the follow-up period, 2 recipients died due to non-biliary complication factors (1 donor liver with type 1 bile duct anatomical model and 1 donor liver with 3a bile duct anatomical model). Conclusion:The anatomical classification of right intrahepatic bile duct of donor liver in SLT is mainly classical bile duct anatomical model, and the bile duct reconstruction scheme is mainly common bile duct of donor liver end-to-end anasto-mosis to common bile duct of recipient.
RESUMO
Objective:To study the application effect of family integrated ward in maintaining the optimal target pulse oxygen saturation (SpO 2) in premature infants with bronchopulmonary dysplasia (BPD). Methods:This was a retrospective cohort study. Premature infants with BPD admitted to the neonatal intensive care unit of Children's Hospital of Nanjing Medical University from June 2019 to January 2022 were enrolled. Based on whether to stay in family integrated ward and implement family integrated care (FICare), these premature infants were divided into the family ward group and the control group. The ratio of optimal target SpO 2 within 24 h before discharge, the duration of home oxygen therapy, and ratio of readmission due to respiratory disease within 6 months after discharge were analyzed between the two groups. Results:During the study period, a total of 167 premature infants with BPD were admitted, including 101 in the family ward group and 66 in the control group. Compared with the control group, the family ward group showed a higher proportion of achieving the optimal target SpO 2 within 24 h before discharge (58.0% vs. 24.0%), shorter duration for home oxygen therapy (7.0 d vs. 12.0 d), and a lower readmission rate within 6 months after discharge (16.5% vs. 30.2%), which had statistically significant difference (all P<0.05). Further regression analysis showed that participating in the family integrated ward significantly reduced the demand for home oxygen therapy and the duration of home oxygen therapy, but had no significant impact on the readmission rate within 6 months after discharge. Conclusions:Family integrated ward can effectively increase the proportion of achieving the optimal target SpO 2 for premature infants with BPD within 24 h before discharge, reduce the demand for home oxygen therapy, and shorten the time of home oxygen therapy after discharge, which is beneficial for improving the living quality of premature infants with BPD.

RESUMO
Objective:To investigate the effect of pelvic rotation around coronal axis on the placement angle of acetabular prosthesis after total hip arthroplasty.Methods:According to Murary's definition, the angle between the acetabular axis and the sagittal plane was defined as the acetabular abduction angle, and the angle between the acetabular axis and the coronal plane as the anterior inclination angle. A simple mathematical solid geometry model was established by using the mathematical software GeoGebra to simulate the dynamic changes of the acetabular prosthesis when it rotated around the coronal axis, and the calculation formula of the dynamic changes of the anterior inclination and abduction angle of the acetabular prosthesis was derived. MatLab software was used to generate the function graph of pelvis forward inclination and abduction angle and deduce the motion of acetabular prosthesis.Results:The dynamic changes of acetabular tilt angle and abduction angle when the pelvis rotated around the coronal axis were functionally related to the anterior-posterior tilt of the pelvis in a nonlinear pattern. When the pelvis rotates around the coronary axis, the anterior inclination angle formula is α 1=arcsin (sinβ 1×cosα×cosθ+cosβ 1×sinα); When the acetabulum axis faces downwards the abduction angle formula is θ 1=arccot (cosβ 1×cotθ-sinβ 1×tanα/sinθ); When the acetabulum axis faces upwards the abduction angle formula is θ 1=π-abs[arccot (cosβ 1×cotθ-sinβ 1×tanα/sinθ)] withα being the initial acetabular forward angle, θ being the initial acetabular abduction angle, α 1 being the forward angle of the acetabular prosthesis after pelvic rotation, θ 1 being the external expansion angle of the acetabular prosthesis after pelvic rotation and β 1 being the rotation angle of the pelvis around the coronal axis. When the pelvis is tilted backward, the anterior inclination angle of the acetabular prosthesis increases first and then decreases, and the abduction angle continues to increase. When the pelvis is tilted forward, the abduction angle decreases first and then increases, and the anterior inclination angle continues to decrease to negative. Conclusion:When the initial anterior inclination angle and abduction angle of acetabular prosthesis change, the curve of anterior inclination and abduction angle change accordingly. The larger the initial anterior inclination angle is, the faster it reaches its peak value, and the larger the peak value is, the faster the abduction angle changes. The larger the initial abduction angle is, the slower the initial anterior inclination angle and the abduction angle change.
RESUMO
Objective To explore the effect of nursing intervention based on the integrated theory of health behavior change(ITHBC)on the health behavior of patients with diabetes retinopathy(DR).Methods 157 patients with diabetes retinopathy admitted from July to December 2022 in a tertiary A hospital in Wuhan,Hubei Province,were selected as the experimental group by convenience sampling method,while 156 patients with diabetes retinopathy hospitalized from January to June 2022 were selected as the control group,and routine nursing was caried out.The disease cognition scale scores,self-management scale scores,and quality of life scale scores were compared between the 2 groups before and after 6 months of intervention.Results After 6 months of intervention,the disease cognition scale scores,self-management scale scores,and quality of life scale scores of both groups improved,and the results in the experimental group were better than these in the control group,and the difference is statistically significant(P＜0.05).Conclusion Nursing interventions based on the ITHBC theory can help improve the disease cognition of DR patients,establish and maintain healthy behaviors,improve their self-management level,and improve their quality of life.
RESUMO
Pulmonary fibrosis， chronic obstructive pulmonary disease， acute lung injury， asthma， and infectious pneumonia are common pulmonary inflammatory diseases worldwide. There is evidence that mitochondria produce a large amount of reactive oxygen species （ROS） when stimulated by inflammation， leading to oxidative stress that affects the onset and progression of pulmonary inflammatory diseases. With in-depth research， traditional Chinese medicine （TCM） has made significant progress in the treatment of pulmonary inflammatory diseases. An increasing amount of evidence indicates that single TCM and their active components， as well as TCM compound formulas， can improve mitochondrial oxidative stress status through multi-target and multi-pathway mechanisms， thereby effectively treating pulmonary inflammatory diseases. Currently， there is a lack of systematic review and summary of TCM research in this field both domestically and internationally. Therefore， this article aims to summarize and conclude the mechanisms by which TCM regulates mitochondrial oxidative stress to intervene in pulmonary inflammatory diseases， providing a scientific basis for its clinical application and offering new ideas and references for in-depth research on the prevention and treatment of pulmonary inflammatory diseases with TCM.
RESUMO
AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.
RESUMO
Chronic obstructive pulmonary disease （COPD） is a heterogeneous disease characterized by incompletely reversible airflow limitation that progresses over time. Its recurrent and incurable nature imposes a significant health burden on patients. The pathogenesis of COPD is complex and has not been fully elucidated. Currently， Western medicine is commonly used in clinical treatment， which often yield suboptimal results and may lead to adverse reactions and drug resistance. Therefore， finding an effective and safe treatment method is a crucial focus in medical research. With the ongoing advancement in disease research， many scholars have discovered that traditional Chinese medicine （TCM） can target various signaling pathways such as nuclear factor-kappa B （NF-κB）， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， mitogen-activated protein kinase （MAPK）， neurogenic locus notch homolog protein （Notch）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， transforming growth factor-β （TGF-β）/Smad， secreted glycoprotein （Wnt）， Hippo， and nuclear factor erythroid 2-related factor 2 （Nrf2）. By influencing these pathways， TCM can affect airway mucus secretion， inhibit inflammation and oxidative stress， alleviate airway and microvascular remodeling， and regulate apoptosis and autophagy， ultimately reducing disease symptoms and improving lung function. TCM has thousands of years of clinical practice experience in treating COPD， demonstrating significant efficacy. Therefore， delving deeply into this from a cellular and molecular perspective can provide a reliable theoretical basis for the clinical application of TCM in treating COPD. However， systematic summaries of how TCM regulates COPD-related signaling pathways are scarce. This article aimed to extensively review and summarize recent literature in China and abroad on interventions of TCM monomers or compound prescriptions in COPD， identifying multiple related pathways to provide new insights for future clinical formulation and experimental research. Integrating basic TCM theories with modern pharmacological research mechanisms can jointly propel the development of TCM in the prevention and treatment of COPD.
RESUMO
Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.
