Objective:To explore the effects of Tongdu Tiaoshen acupuncture on vascular endothelial function and inflammatory factors in patients with mild cognitive impairment (MCI) after ischemic stroke (IS).Methods:A retrospective analysis was performed on the clinical data of 71 patients with MCI after IS in the hospital between January 2020 and September 2022. According to different treatment methods, they were divided into Tongdu Tiaoshen acupuncture group ( n=31, Tongdu Tiaoshen acupuncture + oral nimodipine tables) and routine body-acupuncture group ( n=40, routine body-acupuncture group + oral nimodipine tables). Both groups were treated for 2 courses (14 d/course). Before and after treatment, levels of serum NO and endothelin-1 (ET-1) were detected by radioimmunoassay, and levels of serum basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF), plasma homocysteine (Hcy) and IL-6 were detected by ELISA. The cognitive function of patients was evaluated and intelligence level by Montreal Cognitive Assessment Scale (MoCA), Mini-Mental State Examination(MMSE) and the clinical curative effect was also evaluated. Results:The total response rates in Tongdu Tiaoshen acupuncture group and routine body-acupuncture group were 90.32% (28/31) and 70.00% (28/40), and the difference between the two groups was statistically significant ( χ2=4.33, P=0.037). After treatment, levels of plasma Hcy and IL-6 in Tongdu Tiaoshen acupuncture group were lower than those in the routine body-acupuncture group ( t=2.57, 9.36, P<0.05 or P<0.01). After treatment, levels of serum bFGF, VEGF and NO in Tongdu Tiaoshen acupuncture group were significantly higher than those in the routine body-acupuncture group ( t=10.03, 9.29, 8.17, P<0.01), while ET-1 level was significantly lower than that of the routine body-acupuncture group ( t=2.41, P=0.019). After treatment, MoCA score [(28.24±4.45) vs. (25.32±4.34), t=2.78], MMSE score [(28.73±1.44) vs. (28.02±1.22), t=2.25] in Tongdu Tiaoshen acupuncture group were higher than those in the routine body-acupuncture group ( P<0.01). Conclusion:Tongdu Tiaoshen acupuncture is beneficial to improve vascular endothelial function, reduce levels of inflammatory factors, promote the recovery of cognitive function and improve curative effect in patients with MCI after IS.

Septic shock has always been a challenging problem for people,with a high incidence rate and mortality.After decades of development,significant progress has been made in the pathophysiology and clinical aspects of septic shock.The"Surviving Sepsis Campaign"guidelines provide a suitable approach to directing treatment,enabling earlier recognition of septic shock and reducing its mortality rate.However,there are still many challenges,such as refractory septic shock(RSS)and multiple organ failure.Over the past decade,extracorporeal membrane oxygenation(ECMO)technology has been increasingly applied in the treatment of critically ill patients.Whether ECMO can be considered as a salvage treatment for RSS is increasingly being considered.This report presents the experience of successfully treating a patient with RSS using ECMO in our department.For the management of RSS,it is recommended to consider ECMO as a worthwhile option,providing some practical experience for the treatment of RSS with ECMO.

Objective To analyze the causes of acute intestinal obstruction after intracerebral hemorrhage,and the therapeutic effect of rectal dripping with Dachengqi decoction and Fusu agent on acute intestinal obstruction complicated with septic shock.Methods The clinical data of a patient with acute intestinal obstruction complicated with septic shock after intracerebral hemorrhage,who was admitted to the Hospital of Chengdu University of Traditional Chinese Medicine(TCM)on March 5,2022,were retrospectively analyzed.The study aimed to observe the effects of rectal dripping with TCM on the recovery of intestinal function and improvement of shock.Results The patient was a 52-year-old male who underwent"left temporal craniotomy intracranial decompression,craniocerebral hematoma removal,cerebrospinal fluid leak repair"on February 19,2022 due to cerebral hemorrhage.On the 7th day after operation,the patient had hiccups and abdominal distension,and after treatment,the patient developed fever,consciousness disorders,hypotension and other symptoms.Abdominal CT showed extensive intestinal fluid,gas and expansion.Hemodynamic monitoring indicated high discharge and low resistance,intra-abdominal pressure was 21 cmH2O(1 cmH2O≈0.098 kPa),and laboratory examination showed increased inflammatory indexes and abnormal biochemical indexes.The western medicine diagnosis was acute intestinal obstruction complicated with septic shock,and the symptomatic treatments such as organ support(lung,circulation,kidney),anti-infection,fluid resuscitation,analgesia and sedation were given.The TCM diagnosis was intestinal knot(yangming visceral substantive,sudden collapse of yang-qi),with treatment principles focusing on tongfu heat relief,wenshen qianyang,Dachengqi decoction and Fusu agent was added and reduced according to the syndrome differentiation,with medications administered rectally.After the use of TCM decoction,the patient's defecation volume increased significantly,the intra-abdominal pressure decreased to the normal range,abdominal distension was significantly reduced,and the shock was relieved.On the 17th day after the operation,the patient's symptoms improved,the respiratory cycle was stable,and the patient was successfully transferred out of intensive care unit(ICU).Conclusion The treatment of acute intestinal obstruction complicated with septic shock by rectal dripping with Dachengqi decoction and Fusu agent can quickly relieve the condition and promote the recovery of intestinal function.

Objective To enhance the quality of medical services in the intensive care unit(ICU)of provincial traditional Chinese medicine(TCM)hospitals.Methods In November 2023,Sichuan Provincial Critical Care Medicine Quality Control Center of TCM launched the"quality control supervision project scoring standard for critical care medicine of TCM"to conduct quality control evaluation and business guidance for all TCM hospitals with independent ICU.The survey covered structural indicators,control indicators,participation of TCM,development of new technologies,and diagnosis and treatment programs for dominant diseases.Results In terms of structural indicators:a total of 110 TCM hospitals in the province have independent ICU,an increase of 1.12 times compared with 2019.The control indicators showed that the ICU patients admission rate was higher than that of the national ICU admission rate in 2017,and the admission rate of patients with acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score≥15 points increased.However,the mortality of ICU exceeded the national average.The implementation of core indicators had been significantly improved,but the incidence of outcome indicators such as ICU ventilator-associated pneumonia(VAP),ICU intravascular catheter-related bloodstream infection(CRBSI),and ICU catheter-related urinary tract infection(CAUTI)had increased since 2019,mainly in secondary hospitals.The average number of new technologies was about(5.5±3.4),the participation rate of TCM decreased,and the dominant diseases increased compared with 2019,mainly sepsis,respiratory failure and hemorrhagic stroke.Conclusions The number of ICU units in TCM hospitals at all levels in Sichuan province has grown rapidly,and key performance indicators have also improved compared to previous periods.However,greater efforts are still needed in preventing the occurrence rates of VAP,CRBSI,and CAUTI.There is a shortage of medical resources allocation,and the imbalance in regional medical resources and professional training remains an urgent issue to be addressed.Additionally,the participation rate of TCM and the dominant diseases need further enhancement.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To summarize long-term clinical follow-up results of segment instability between the upper instrumented vertebra (UIV) and the adjacent upper vertebra (UIV+1) and to establish the optimal timing for surgery for UIV+1.Methods:A retrospective analysis was conducted on 265 patients with lumbar degenerative diseases who underwent transforaminal lumbar interbody fusion (TLIF) surgery at the Department of Spinal Surgery, Zhongda Hospital, from January 2014 to December 2018. The cohort included 119 male and 146 female patients, with an average age of 64.93 years (range: 32-86 years). Preoperative dynamic imaging measured sagittal angulation (SA) and sagittal translation (ST) of the UIV+1/UIV segment. Patients with SA>10° or ST>2 mm were categorized into the unstable group, further divided into the unstable non-fusion group and the unstable fusion group based on whether UIV+1 expansion fusion was performed. The remaining patients were classified into the stable group. Imaging indicators, Visual Analogue Scale (VAS) scores, Oswestry disability index (ODI) scores, and Japanese Orthopaedic Association (JOA) scores were compared among the groups, with JOA improvement rates calculated to assess clinical efficacy. Pearson correlation coefficient analysis was employed to examine correlations between preoperative imaging indicators and final follow-up JOA improvement rates. Receiver Operating Characteristic (ROC) curves and the maximum Youden index were utilized to determine thresholds for preoperative SA and ST.Results:The follow-up duration for all patients was 73.53±12.92 months (range: 61-108 months). The stable group (124 cases) included 61 males and 63 females, aged 64.31±9.83 years (range: 44-82 years). The unstable non-fusion group (59 cases) included 22 males and 37 females, aged 65.76±11.01 years (range: 32-86 years). The unstable fusion group (82 cases) included 36 males and 46 females, aged 65.26±8.68 years (range: 47-80 years). At the last follow-up, the unstable non-fusion group exhibited ΔSA 0.90°±1.97° and ΔST 0.77±1.27 mm, both significantly higher than the stable group's ΔSA 0.25°±1.57° and ΔST 0.34±0.34 mm ( t=3.564, P<0.001; t=2.311, P=0.022). Clinical improvements were lower in the unstable non-fusion group compared to the other two groups: VAS (2.28±0.83), ODI (5.91%±3.46%), JOA (24.11±1.78), with a JOA improvement rate of 60%. The stable group showed VAS (1.51±0.69), ODI (3.71%±1.75%), JOA (27.33±1.91), with a JOA improvement rate of 83%. The unstable fusion group had VAS (1.46±0.83), ODI (3.46%±1.81%), JOA (26.48±1.66), with a JOA improvement rate of 78%. These differences were statistically significant ( F=32.117, P<0.001; F=24.827, P<0.001; F=92.658, P<0.001; F=93.341, P<0.001). The JOA improvement rate was negatively correlated with preoperative SA ( r=-0.363, P<0.001) to a low extent, and with preoperative ST ( r=-0.596, P<0.001) to a moderate extent. ROC curve analysis determined the preoperative SA threshold as 11.5° and the preoperative ST threshold as 1.85 mm. Conclusion:Pre-existing instability of the responsible segment UIV and UIV+1 (SA>10° or ST>2 mm) may worsen during long-term follow-up after TLIF. When preoperative SA exceeds 11.5° and ST exceeds 1.85 mm between UIV and UIV+1, performing an extended fusion involving UIV+1 can ensure surgical efficacy over long-term follow-up.

AIM:To explore the impact of sphingosine 1-phosphate receptor 5(S1PR5)on lipopolysaccha-ride(LPS)-induced neuroinflammation and cognitive-behavioral impairments in mice,alongside the anti-inflammatory im-pacts on BV2 cells and associated mechanisms.METHODS:(1)C57BL/6 wild-type(WT)mice and homozygous S1PR5 knockout(KO)mice were utilized and categorized into WT control,WT-LPS,S1PR5 KO control,and S1PR5 KO-LPS groups using the random number method.Neuroinflammatory models in mice were induced by a single intraperitoneal injection of 5 mg/kg LPS in the WT-LPS and S1PR5 KO-LPS groups,while an equivalent volume of saline was injected in-to the WT control and S1PR5 KO control groups.Following 7 days of modeling,the Morris water maze test was conducted,followed by the collection of brain tissues from each group of mice.Hippocampal tissue sections were stained with Nissl.The mRNA expression levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and IL-6 in hippocampal tis-sues were determined using RT-qPCR.Western blot and tissue immunofluorescence techniques were employed to assess the expression of nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)in hippocampal tissues.(2)The BV2 cells underwent LPS stimulation to induce an inflammatory response and were treated with either the S1PR5 ago-nist A971432 or lentiviral overexpression of S1PR5.The effects of S1PR5 agonism or overexpression on S1PR5,IL-1β,IL-6,TNF-α,and CD206 were assessed using RT-qPCR.Additionally,CD206 expression was examined via cellular im-munofluorescence.Western blot was employed to analyze the protein levels of microglia polarization markers CD206,in-ducible nitric oxide synthase(iNOS),cyclooxygenase 2(COX2),and NLRP3,as well as p-NF-κB,cleaved caspase-1,and IκBα.RESULTS:(1)Findings from in vivo experiments indicated that S1PR5 KO notably exacerbated LPS-induced memory impairments in mice,alongside increased mRNA levels of IL-1β and IL-6,and increased protein levels of NLRP3 in the hippocampus.(2)The presence of S1PR5 in BV2 cells remained unaffected by variations in A971432 concentration and exposure duration.(3)Activation of S1PR5 or its overexpression significantly mitigated LPS-induced expression of IL-1β,IL-6,and TNF-α,while concurrently enhancing CD206 expression in BV2 cells at the mRNA level.At the protein level,it led to a noteworthy increase in CD206 expression,indicative of M2-type macrophages,and a reduction in the ex-pression of iNOS and COX2,markers of M1-type macrophages.Furthermore,it downregulated NLRP3,p-NF-κB,and cleaved caspase-1 expression,while upregulating IκBα expression.CONCLUSION:S1PR5 deficiency exacerbates cog-nitive deficits in mice by promoting neuroinflammatory responses induced by LPS.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Background: and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. Methods: This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. Results: Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). Conclusion In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.

Objective:To analyze the distribution characteristics of traditional Chinese medicine (TCM) syndromes in patients with coronavirus disease 2019 (COVID-19) in plateau areas, and to provide theoretical basis for further clinical treatment of patients with COVID-19.Methods:From August 9 to August 24, 2022, patients with COVID-19 admitted to the Third People's Hospital of Tibet Autonomous Region (designated hospital for COVID-19) were included, and their baseline characteristics (age, gender, source), clinical classification and distribution of TCM syndrome types were collected and analyzed. Data analysis was performed using SPSS 26.0 statistical software.Results:A total of 161 COVID-19 patients were enrolled with ethnic distribution: 124 (77.02%) Tibetans, 35 (21.74%) Han, and 2 (1.24%) Hui, 68 males and 93 females. The male-to-female ratio was 0.73∶1. Aged 1 to 94 years, the average age was (39.06±23.64) years old, of which 4 patients were under 1 year old (excluded because the information was missing). A total of 157 patients were enrolled, and 124 patients (78.9%) were under 60 years old, including 120 cases of common type, 4 cases of severe type, 0 cases of critical type, 7 cases over 80 years old, 1 case over 90 years old, and 32 cases under 18 years old. The clinical manifestations of the patient are mainly cough, expectoration, fever, aversion to cold, dry throat, headache, fatigue, running nose, dry mouth, bitter mouth, etc. Most of the tongue is pale, red, and white greasy moss or thin white coating. In TCM, the most common syndrome was cold-dampness blocking lung syndrome (99 cases, 63.06%), followed by cold-dampness stagnant lung syndrome (22 cases, 14.01%), damp-heat accumulating lung syndrome (22 cases, 14.01%), and humidity stagnant lung syndrome (11 cases, 7.01%). Syndromes of epidemic (2 cases, 1.27%), epidemic toxins blocking the lung pattern (1 cases, 0.64%), toxins with dryness intense heat in both qi and ying phases pattern (0 cases) accounted for less than 2%, and the distribution of various syndrome types in COVID-19 patients was uneven ( χ2 = 0.48, P < 0.05). Conclusion:The most common TCM syndromes of COVID-19 patients in Lhasa are cold-dampness blocking lung syndrome, followed by cold-dampness stagnant lung syndrome, damp-heat accumulating lung syndrome, and humidity stagnant lung syndrome.
