ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4（TLR4）/nuclear transcription factor-kappa B（NF-κB）/absent in melanoma 2（AIM2）inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2^h4 mice were selected and randomly divided into control group， model group， low， medium and high dose groups of Buzhong Yiqitang （4.78， 9.56， 19.12 g·kg^-1）， and western medicine group （selenium yeast tablets， 3.033×10^-5 g·kg^-1）. The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model， and the control group drank ad libitum distilled water. Eight weeks later， the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye， and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） was measured by enzyme-linked immunosorbent assay （ELISA）， and Real-time PCR was used to detect the expression of HMGB1， TLR4， AIM2， NF-κB p65，apoptosis-associated speck-like protein（ASC），cysteinyl aspartate-specific protease-1（Caspase-1）， IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 （HMGB1）， TLR4， AIM2， NF-κB p65， phosphorylation（p）-NF-κB p65， ASC， Caspase-1， and IL-1β proteins in thyroid tissue， and immunofluorescence staining was used to observe the protein expression of HMGB1， AIM2， and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group， the thyroid tissue of mice in the model group was significantly swollen， the spleen quality was significantly increased， and the expression of HMGB1， TLR4， NF-κB p65， AIM2， ASC， Caspase-1， IL-1β in thyroid tissue was significantly increased （P<0.01）. Compared with the model group， the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved， the quality of spleen was significantly reduced， and the expression of HMGB1， TLR4， AIM2， NF-κB p65， p-NF-κB p65， ASC， Caspase-1， IL-1β in thyroid tissue was significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT， and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

Objective:To analyze the epidemiological characteristics of hospitalized patients diagnosed with sepsis in a large class Ⅲ general hospital in Southwest China in a period of 2 years, and to explore the risk factors related to death in patients with sepsis.Methods:A retrospective study was conducted to select patients with sepsis admitted to Sichuan Provincial People's Hospital from September 1, 2021 to August 31, 2023, and general characteristics such as gender, age, discharge diagnosis, discharge department, hospitalization cost, length of stay, and prognosis during hospitalization were collected. The baseline of two groups of patients were compared, and the risk factors of in-hospital cause of death in patients with sepsis were analyzed by multivariate Logistic regression.Results:A total of 3 568 patients with sepsis were included with median age of 58 (35, 74) years old. Of all patients, there were 2 147 males (60.17%). The median length of hospitalization was 13 (8, 24) days, and the median hospitalization cost was 3.98 (1.87, 8.83) ten thousand yuan. The departments with more than 100 cases of sepsis in 2 years were central intensive care unit (ICU), pediatrics department, nephrology department, emergency medicine department, emergency intensive care unit (EICU), infectious department, respiratory medicine department, hematology department, neonatal care unit and emergency surgical department. A total of 1 210 patients (33.91%) admitted to ICU (including central ICU and EICU). The hospitalization cost of ICU patients were higher [6.7 (3.1, 15.5) ten thousand yuan], the hospitalization duration was longer [9 (3, 17) days], and the mortality was higher [35.29% (427/1 210)]. Among 3 568 patients with sepsis, 448 died and 3 120 survived during hospitalization. The age, male proportion and hospitalization cost of patients with sepsis in the death group were significantly higher than those in the survival group [age (years old): 75 (60, 86) vs. 57 (30, 71), male proportion: 67.86% (304/448) vs. 59.07% (1 843/3 120), hospitalization cost (ten thousand yuan): 6.7 (3.0, 16.9) vs. 3.7 (1.8, 8.1)], the ratio of diabetes mellitus was significantly lower than that of survival group [4.91% (22/448) vs. 10.45% (326/3 120)], the length of hospitalization was shorter than that of survival group [days: 10.0 (3.0, 19.0) vs. 13.0 (8.0, 24.0)], the differences were statistically significant (all P < 0.01). Multivariate Logistic regression analysis showed that male [odds ratio ( OR) = 0.75, 95% confidence interval (95% CI) was 0.59-0.96], elder ( OR = 1.04, 95% CI was 1.03-1.05) and diabetes ( OR = 0.32, 95% CI was 0.19-0.54) were independent risk factors for in-hospital death in patients with sepsis (all P < 0.05). Conclusions:Sepsis is a heavy burden in Southwest China, especially for ICU, with high mortality, high hospitalization costs, and heavy economic burden on patients and society. Male, elder and diabetes were independent risk factors for in-hospital death of sepsis patients.

[Objective]To explore the therapeutic characteristics,technical points and disease spectrum distribution of clinical studies on five-tone therapy,and to provide a reference for the scientific design and implementation of clinical trials on five-tone therapy.[Methods]Retrieve randomized controlled trial(RCT)literature on five-tone therapy from 9 major databases including China National Knowledge Infrastructure(CNKI),VIP,Wanfang Data,China Biology Medicine disc(CBMdisc),PubMed,Embase,Web of Science,Cochrane Library,and Clinical Trails.Extract information such as literature titles,first authors,symptoms,and intervention measures.Use bibliometric methods to analyze the sample size,intervention methods,treatment frequency,treatment environment,control methods,and symptom spectrum of the included studies.[Results]The sample size of the inclusion of 491 articles was mostly focused on 60～100 patients(60.08%),and five-tone therapy was often used in combination with auricular acupressure,traditional Chinese medicine and acupuncture.Treatment frequency<1 session per day,treatment duration<30 min/session and treatment duration>28 days were the main treatment characteristics.Control measures can be categorized into four types:Chinese medical treatment,western medical treatment,music therapy and blank control,with western medical treatment being used most frequently(446 times).Totally 314 articles(63.95%)reported specific varicosities,of which the Jue tone was the highest,for a total of 108 times.Music therapy involved a total of 66 conditions,which were distributed among 17 disease systems,and the top three most frequent appropriate disease systems were mental and behavioral disorders(112 articles),neurological disorders(76 articles),and oncological disorders(71 articles).[Conclusion]The five-tone therapy has a wide range of indications and great potential for clinical application,but there is still a need to establish standardized standards in terms of treatment time,course of treatment,and other technical aspects.In the future,it is still necessary to design and implement more scientific experimental plans to promote the rational application and promotion of five-tone therapy.

Objective:To systematically integrate the attitudes and experiences of medical staffs towards the family presence during resuscitation and provide a reference for the development of family presence during resuscitation clinical practice in China.Methods:To search PubMed, Embase, Web of Science, The Cochrane Library, CINAHL, CNKI, CBM and Wanfang database for qualitative studies on medical staff's attitudes and experiences of family presence during resuscitation since its inception to August 2022. The quality of the literature was evaluated using the Australian JBI Centre for Evidence-Based Health Care (2017) quality assessment criteria for qualitative studies, which were integrated using a pooled integration approach.Results:A total of 12 papers were included to distil the findings of 74 studies, which were summarized to form 10 new categories and 4 consolidated findings including medical staffs′ attitudes towards and reasons for family presence during resuscitation, the impact of family presence during resuscitation on the resuscitation team, the impact of family presence during resuscitation on patients and families, and the real-life dilemmas and recommendations for medical staffs to allow family presence during resuscitation.Conclusions:We should pay attention to the difficulties and needs of family presence during resuscitation by medical staff, take into account the medical context in China, and improve the humanistic care system in our hospitals by considering hospital management, clinical practice, and the demands of patients and their families, in order to improve the accessibility of family presence during resuscitation by the medical staff.

Objective:To understand the current situation of knowledge, attitude and practice about target temperature management (TTM) in patients with severe traumatic brain injury (STBI) among intensive care unit ICU nurses and analyze the influencing factors, so as to provide a reference for conducting ICU nurses′ TTM training for patients with STBI.Methods:Applying the method of cross-sectional study, from November to December 2022, a stratified whole-group sampling method was used, stratified by first-, second-, and third-level hospitals, and a self-designed questionnaire on the current status of ICU nurses′TTM for patients with STBI was used to investigate the current status of knowledge, attitude, and practice of neurosurgical ICU, emergency ICU, and comprehensive ICU nurses in 22 second- and third-level hospitals in 11 cities in Gansu Province, and multiple linear regression analysis was used to analyze the factors influencing ICU nurses′ knowledge, attitude, and practice scores.Results:A total of 543 valid questionnaires were returned, and the scores of ICU nurses on the TTM total score, knowledge, attitude and practice dimensions of STBI patients were (76.75 ± 10.42), (7.38 ± 2.74), (39.57 ± 4.87), (29.80 ± 7.18) points respectively. The results of multiple linear regression analysis showed that the factor influencing ICU nurses′ scores on the TTM knowledge dimension for STBI patients was having attended TTM-related training ( t = 2.16, P<0.05); the factors influencing ICU nurses′ scores on the TTM attitude dimension for STBI patients were college, bachelor′s degree and the position of nurse practitioner ( t = 2.65, 2.91, 2.14, all P<0.05); and the factors influencing ICU nurses′ scores on the TTM practice dimension for STBI patients were the age group of 36 to 45 years old, the department having TTM-related criteria and having knowledge of TTM-related guidelines ( t = -2.46, 2.64, 3.85, all P<0.05). Conclusions:ICU nurses have a more positive attitude toward TTM in patients with STBI, but the level of knowledge and practice needs to be improved. Managers should conduct relevant training according to the current situation and influencing factors to improve ICU nurses′ knowledge and practice of TTM in patients with STBI, ensuring the effectiveness and safety of TTM.

Objective:To systematically evaluate the distribution characteristics of traditional Chinese medicine (TCM) syndromes in adult influenza patients and to provide a basis for the TCM syndrome differentiation of influenza.Methods:The CNKI, CBM, Wanfang, VIP, PubMed, Embase, Cochrane Library databases were searched to collect cross -sectional studies on the distribution pattern of TCM syndromes in adult patients with influenza. The risk of bias assessment tool for cross -sectional studies developed by the Joanna Briggs Institute (JBI) evidence -based health care center was used to evaluate the literature quality, and the Stata 15.1 software was used to conduct a Meta -analysis of the pooled effect sizes of the included studies. Results:A total of 11 studies with 4 367 influenza patients were included. Quality assessment results of JBI showed that the risk bias was higher in the sample size calculation, and the description of sampling modalities and response rate was unclear. There were 17 influenza syndromes after specification, and a single group rate Meta -analysis was performed of the syndromes with ≥ 50 incident cases showed that there were 9 syndromes with an incidence ≥ 10% and statistical significance, the top 5 syndromes were syndrome of wind and heat invading the defense [ n = 1 583, RATE = 34.3%, 95% confidence interval (95% CI) was 22.2%-46.3%], syndrome of exterior cold and interior heat ( n = 1 122, RATE = 36.1%, 95% CI was 21.2%-51.1%), syndrome of wind -cold fettering the exterior ( n = 860, RATE = 19.4%, 95% CI was 10.7%-28.0%), syndrome of heat and toxin in the lung ( n = 217, RATE = 17.1%, 95% CI was 9.1%-25.0%), and syndrome of disease involving both defense phase and qi phase ( n = 184, RATE = 38.8%, 95% CI was 14.2%-63.5%). The results of the subgroup analysis in different geographical regions showed that the frequency of distribution of syndrome of wind and heat invading the defense and heat and toxin in the lung was higher in the South (RATE: 36.5%, 18.6%) than in the North (RATE: 30.9%, 15.4%), and the frequency of distribution of syndrome of wind -cold fettering the exterior and exterior cold and interior heat in the North (RATE: 23.8%, 40.1%) was higher than that in the South (RATE: 15.7%, 32.3%). Conclusions:There are 9 common TCM syndromes of influenza, including wind and heat invading the defense syndrome, exterior cold and interior heat syndrome, wind -cold fettering the exterior syndrome, heat and toxin in the lung syndrome, disease involving both defense phase and qi phase syndrome, wind and heat complicated by dampnessinvading the surface syndrome, wind and cold complicated by dampnessinvading the surface syndrome, defense phase syndrome and dampness and heatinvading the surface syndrome, which can provide a reference for the TCM syndrome differentiation and treatment of influenza.

Pre-rheumatoid arthritis （Pre-RA） is the asymptomatic state of rheumatoid arthritis （RA）， and its progression showed complexity， dynamics and significant individual differences. The dynamic prediction model is valuable in identifying individual risks and taking timely preventive and control measures. It is believed that applying the dynamic prediction model to traditional Chinese medicine （TCM） clinical studies of Pre-RA is expected to predict the critical state of Pre-RA to RA， reveal the evolution of Pre-RA， reflect the external authenticity of the TCM clinical studies， and complement the clinical efficacy evaluation method. Accordingly， it is envisioned to construct a dynamic prediction model for Pre-RA progression based on TCM clinical trial data through the dynamic prediction model algorithm， and to apply long-term follow-up cohort data for external validation， thereby providing a basis for scientific warning and clinical decision-making on the evolution of Pre-RA.

Objective:To investigate the clinical effect of Infix combined with hollow screws for the treatment of pelvic injuries with pubic symphysis separation in middle-aged and elderly patients.Methods:Data of 8 middle-aged and elderly patients with pelvic injuries due to pubic symphysis separation undergone treatment from January 2017 to December 2020 were retrospectively analyzed.Results:The average operating time of 8 patients was (46.0±6.2)min(range: 40-62min); the average intraoperative blood loss was (32.0±5.6)ml(range: 25-50 ml); the average length of incisions at the iliac screw was(2.6±0.4)cm(range: 2.0-3.5 cm); the average length of incisions at the hollow screw was (1.1±0.3)cm(range: 0.8-1.5 cm); and the average times of fluoroscopy were (36.0±6.0)times(range: 28-52 times). Postoperative X-ray and CT examinations showed that the reduction of the pubic symphysis was good, the inserted iliac screws and cannulated screws were positioned accurately, and the incision healed well.Based on Matta's criteria, postoperative radiological outcomes were evaluated, with 7 cases rated as excellent and 1 as good, giving an excellent to good rate of 100%(8/8). The average followed up time for all 8 patients was (15.0±4.2)months(range: 6-24 months). Pelvic X-ray and CT examinations at the last follow-up showed that the fractures healed well and the pubic symphysis reduction did not fail.Infix and cannulated screws in the pubic symphysis were removed 10-12 weeks after surgery[average: (10.5±0.5)weeks]. According to the Majeed Pelvic Score, 5 cases were rated as excellent, 2 cases as good and 1 as fair, with an excellent to good rate of 87.5%(7/8). One patient had symptoms related to the lateral femoral cutaneous nerve that disappeared after 3 months.One patient developed deep venous thrombosis after surgery, and the filter was placed and removed 10 weeks later.Conclusions:Using Infix plus cannulated screws for the treatment of pelvic injuries in middle-aged and elderly patients with pubic symphysis separation has the advantages of limited trauma and intraoperative blood loss, good fixation and few complications.

Objective:To investigate the clinical effect of using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring.Methods:Data of 7 patients with old vertical unstable fracture dislocation of posterior pelvic ring admitted and followed up from January 2017 to April 2020 were retrospectively analyzed, including 4 males and 3 females with an average age of 42.4 years old (range, 22-73 years old). There were 3 cases of traffic injury, 3 cases of falling injury and 1 case of tumble injury. According to Tile classification for pelvic fractures, there were 5 cases of type C1, 1 case of type C2 and 1 case of type C3. The average time from fracture to surgery was 5.4 weeks (range, 3-10 weeks). Among the 7 patients, 4 patients' posterior ring fractures were fixed by combined lumbar pelvic triangle fixation, and 3 patients' posterior ring fracture were fixed by combined lumbar pelvic fixation. 4 patients' anterior ring injury were not treated, 2 patients' anterior ring injury were treated by closed cannulated screw and internal fixation, and 1 patient's anterior ring injury was fixed by INFIX and cannulated screw. Every patient's operating time, intraoperative blood loss, length of incision and times of X-ray fluoroscopy were recorded. Pelvic X-ray and CT scan were taken postoperatively to observe the condition of reduction and screw position. Postoperative fracture reduction quality was assessed by Matta radiological criteria and Majeed criteria was used at the final follow-ups to evaluate the degree of functional recovery after pelvic fracture.Results:The average operating time of 7 patients was 143 min (range, 96-205 min); the intraoperative average blood loss was 579 ml (range, 300-1 650 ml); the average length of incisions was 12.9 cm (range, 9-15 cm) and the average time of X-ray fluoroscopy was 27 times (range, 15-52 times). Postoperative X-ray and CT scan showed that the displacements of the posterior rings were reset well and all the hollow screws were located accurately and firmly. Postoperative radiation quality was evaluated according to Matta radiological criteria, and there were 4 cases of excellent, 2 cases of good and 1 case of fair, with an excellent and good rate of 85.7% (6/7). Seven patients had good fracture union. The average followed up time for all 7 patients was 12 months (range, 6-16 months). At the last follow-up, imaging examination showed good reduction of the sacroiliac joint, and the reduction of anterior and posterior rings were not lost. The healing time was 14.2 weeks (range, 12-20 weeks). Majeed score: postoperative 4.90±6.64 points (range, 48-58 points), postoperative 3 months 71.40±7.32 points (range, 67-75 points), postoperative 6 months 84.90±8.14 points (range, 68-96 points), the difference was statistically significant ( F=0.614, P=0.004). Majeed score 6 months after operation showed that 5 cases were excellent, 1 case was good and 1 case was fair, and the excellent and good rate was 85.7% (6/7). Conclusion:Using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring has good reduction quality, high fixed strength and good postoperative effect.

Objective:To systematically evaluate the incidence of coronavirus disease 2019 (COVID-19) syndrome in traditional Chinese medicine (TCM), and to provide a basis for the standard of COVID-19 syndrome differentiation.Methods:CNKI, China Medical Journal Network, PubMed and Embase databases were searched by computer, and TCM syndrome data of COVID-19 cross-sectional surveys and case series were collected from the establishment of the database to March 31st in 2020. Two researchers independently screened the literature, extracted relevant data such as TCM syndromes, and evaluated the quality of the literature according to the quality assessment tool recommended by the JBI Evidence-Based Health Care Center. Stata 14.0 software was used to perform a single-group Meta-analysis of TCM syndromes.Results:Thirteen cross-sectional studies and 5 case series studies were included, with a total of 2 139 patients. The analysis of the cross-sectional studies showed that the risk bias was higher in the identification, control and accuracy of the confounding factors, and the description of the reliability and validity of the outcome indicators was unclear. The analysis of the case series studies showed that the overall risk bias was small, but there was a lack of a comprehensive description of the assessment when selecting patients. A total of 33 TCM syndromes of COVID-19 were sorted out by combining the TCM syndromes with the same disease position and pathogenic syndrome in the included 18 literatures, and there were 10 types of TCM syndromes of which the number of occurrences was ≥50, the incidence rate was ≥10%, and had statistical significance [indicated that 95% confidence interval (95% CI) didn't cross the meaningless line 0], including cold dampness syndrome (469 cases, incidence rate was 28.2%, 95% CI was 5.9%-50.6%), damp heat syndrome (247 cases, incidence rate was 32.1%, 95% CI was 10.7%-53.6%), epidemic closed lung syndrome (228 cases, incidence rate was 28.9%, 95% CI was 12.5%-45.2%), pulmonary and spleen Qi deficiency syndrome (202 cases, incidence rate was 22.1%, 95% CI was 9.5%-34.7%), dampness stagnation lung syndrome (180 cases, incidence rate was 41.2%, 95% CI was 18.4%-64.1%), dampness obstructing lung and spleen syndrome (81 cases, incidence rate was 56.3%, 95% CI was 48.1%-64.4%), evil heat syndrome lung syndrome (76 cases, incidence rate was 31.1%, 95% CI was 25.3%-36.9%), dampness-blocking lung and stomach syndrome (70 cases, incidence rate was 13.4%, 95% CI was 10.4%-16.3%), heat poisoning lung closure syndrome (55 cases, incidence rate was 16.9%, 95% CI was 8.3%-25.5%), and Qi-Yin deficiency syndrome (53 cases, incidence rate was 13.7%, 95% CI was 2.7%-24.8%). Subgroup analysis showed that there were 6 types of TCM syndromes that met the above conditions in cross-sectional studies, namely cold and damp lung syndrome (200 cases, incidence rate was 20.9%, 95% CI was 12.6%-29.2%), damp heat syndrome (221 cases, incidence rate was 41.8%, 95% CI was 9.4%-74.2%), dampness-disease lung syndrome (120 cases, incidence rate was 41.4%, 95% CI was 8.6%-74.3%), lung and spleen Qi deficiency syndrome (115 cases, incidence rate was 19.2%, 95% CI was 6.8%-31.7%), heat-fever lung syndrome (76 cases, incidence rate was 31.1%, 95% CI was 25.3%-36.9%) and Qi-Yin deficiency syndrome (53 cases, incidence rate was 13.7%, 95% CI was 2.7%-24.8%).
