ObjectiveTo explore the possible mechanism of action of Lifei Xiaoji Pill (理肺消积丸, LXP) in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway. MethodsFifty C57BL/6 mice were randomly divided into five groups, model group, LXP group, inhibitor group, LXP + inhibitor group, and cisplatin group, with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day, the model group mice were given 0.2 ml of saline by gavage daily, the LXP group given 240 mg/(kg·d) of LXP solution once a day by gavage, the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/(kg·d) every day, the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day, and the cisplatin group received 0.5 mg/(kg·d) cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose, tumor weight and volume were measured, tumor histopathology was examined by HE staining, apoptosis in tumor tissues was detected by TUNEL staining, and proliferation cell nuclear antigen (PCNA) protein levels were detected by immunohistochemistry. Warburg effect indicators, including glucose concentration, lactate content, and adenosine triphosphate (ATP) production in tumor tissues, were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47, BACH1, hexokinase 2 (HK2), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH). ResultsCompared with the model group, all drug intervention groups showed reduced tumor weight and volume, improved tumor pathology, decreased PCNA positive rate, increased apoptosis rate, and reduced expression levels of USP47, BACH1, and HK2 proteins and mRNA (P<0.05 or P<0.01). Except for lactate content in the cisplatin group, the glucose concentration in tumor tissues of other drug intervention groups increased, while lactate content and ATP production decreased (P<0.05 or P<0.01). Compared with the LXP group, the LXP + inhibitor group showed more significant improvements in these indicators (P<0.05 or P<0.01). Compared with the cisplatin group, the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH, and lower protein levels of USP47 and HK2 (P<0.05 or P<0.01). Compared with the inhibitor group, the cisplatin group had higher HK2 protein levels, while the LXP + inhibitor group showed lower mRNA expression of BACH1, HK2, and GAPDH (P<0.05 or P<0.01). ConclusionLXP significantly inhibits tumor growth in lung cancer mice, and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To analyze the etiological composition and clinical characteristics of infant hypertension,and provide reference for its diagnosis and treatment.Methods:This is a retrospective case-control study.Retrospective investigation and analysis were conducted on the clinical data of infants discharged from Beijing Children's Hospital Affiliated to Capital Medical University with a diagnosis of "hypertension" from June 1,2016 to September 30,2021,including clinical manifestations,auxiliary examinations,treatment plans,and prognosis.Results:A total of 74 eligible children were collected,including 42 male infants(56.8%)and 32 female infants(43.2%).A total of 67 cases(90.5%)had clear secondary factors,including 35 cases of kidney disease(47.3%),12 cases of connective tissue disease(16.2%),and 9 cases of hematological tumor disease(12.2%).At the beginning of the disease,cardiac ultrasound showed that 54 cases(73.0%)had ventricular wall thickening,including mild thickening in 31 cases(57.4%),moderate thickening in 11 cases(20.3%),and severe thickening in 12 cases(22.2%).After grouping by etiology,the incidence of proteinuria and severe hypertension in the renal hypertension group,as well as those receiving multiple antihypertensive drugs,was significantly higher than that in the non-renal hypertension group( χ 2=28.493, P<0.001; χ 2=17.283, P<0.001; χ 2=17.358, P<0.001);Renal disease was risk factor for severe hypertension in infants according to univariate and multivariate logistic regression analysis respectively( OR=11.176,95% CI:2.882~43.339, P<0.001; OR=11.669,95% CI:2.921~46.624, P<0.001).Thirty-one children had follow-up records for 6 months or more,and 13(41.9%)still required antihypertensive treatment,of whom 26(83.9%)were no longer recorded as having elevated blood pressure. Conclusion:Infant hypertension is mainly secondary,with a high proportion of renal factors and predisposition to severe hypertension,which requires multiple antihypertensive drugs for control.Active antihypertensive treatment and removal of secondary factors during the acute phase are helpful for controlling hypertension in infants,but further research is needed on treatment options and long-term prognosis.

Objective:To analyze the application of antitoxin therapy in severe infant botulism.Methods:A retrospective analysis was conducted on 14 cases of severe infant botulism treated at 3 pediatric medical centers from July 2020 to August 2024. This study investigated antitoxin dosage, treatment duration, discontinuation criteria and adverse reactions.Results:A total of 14 cases (12 males and 2 females) were included, with an age of 5.0 (3.8, 7.0) months. Botulinum toxin typing revealed 10 cases of Type B, 2 cases of Type A and 2 untyped cases. The interval from symptom onset to antitoxin administration was 9.0 (6.0, 11.5) d. The initial dosage of type A antitoxin was 12 500 (10 000, 22 500) U, while type B was 5 000 (5 000, 5 000) U. The dosage was tapered in some cases after symptom improvement, the duration of treatment was 16.5 (9.8, 25.3) d. In total, 11 infants discontinued medications after improvement in muscle strength, while 3 infants discontinued treatment after obtaining negative results from fecal mouse bioassays. Adverse events were reported in 2 cases, both of which resulted in rash, and 1 case was complicated with anaphylactic shock. All the patients survived upon discharge with a follow-up period of 11 d to 3 years and 8 months. Totally 12 infants had fully recovered, while 2 infants were still recovering after discharge.Conclusion:Antitoxin therapy is a feasible and safe approach which showed favorable prognosis in severe infant botulism.

Objective:To understand the management of children with pediatric acute liver failure (PALF) in pediatric intensive care unit (PICU).Methods:A retrospective case-control study was conducted. A total of 101 children with PALF hospitalized in PICU of Beijing Children′s Hospital from July 2017 to October 2022 were included. Demographic, clinical management and prognosis data were collected. According to whether PALF was the main diagnosis, the patients were divided into primary diagnosis group and complication group. The primary diagnosis group was subdivided into effective group and ineffective group with routine treatment (except liver transplantation). The intergroup comparisons were performed using independent samples t-test, Mann-Whitney U test, χ2 test or Fisher exact test. Multivariate Logistic regression analysis was employed to identify risk factors associated with prognosis. Results:Among the 101 children with PALF, 58 were male and 43 were female, with an age of 30 (10, 103) months, 60 cases in primary diagnosis group and 41 cases in complication group. There were no significant differences in prothrombin time (PT) and international normalized ratio (INR) between the two groups (both P>0.05), while the total bilirubin, direct bilirubin and blood ammonia were all significantly higher in the primary diagnosis group (all P<0.05). Unoriginal liver failure (25 cases (42%)) and poisoning (13 cases (22%)) were the most common causes of PALF in the primary diagnosis group, while shock (17 cases, 43%) and hemophagocytic syndrome (14 cases (34%)) in the complication group. The mortality rate of the main diagnosis group was significantly lower than that of the complication group (25% (15/60) vs. 61% (25/41), χ2=13.18, P<0.001), as well as the incidence of combined organ function injury, while the amount of plasma used and the ratio of plasma exchange times to PICU hospitalization days were significantly higher (all P<0.05). In the primary diagnosis group, there were 32 cases (53%) in the effective group and 28 cases (47%) in the ineffective group. In the ineffective group, 15 cases (54%) died and 13 cases (46%) were transferred to another site for liver transplantation assessment. The hospitalization time of PICU in the effective group was significantly longer than that in the ineffective group, while the ratio of plasma exchange times to PICU hospitalization days, the average daily hours of continuous renal replacement therapy (CRRT), the rate of CRRT and the average daily plasma dosage in the effective group were all significantly lower than those in the ineffective group (all P<0.05). The worst PT, INR and blood ammonia, and the stage 4 hepatic encephalopathy morbidity and significant bleeding rate in the effective group were all significantly lower than those in the ineffective group (all P<0.05). Multivariate Logistic regression analysis showed that after adjusting for age, sex, total bilirubin, INR and blood ammonia, stage 4 hepatic encephalopathy was the independent risk factor for the failure of routine treatment of PALF ( OR=84.16,95% CI 4.04-1752.37, P=0.004). Conclusions:PT and INR could not specifically represent liver synthetic function in some PICU patients, so current PALF diagnostic criteria for PICU children has limitations. Complicated with stage 4 hepatic encephalopathy was an independent risk factor of the failure of conventional treatment in patients with PALF.

A 55-year-old male patient received immunotherapy combined with chemotherapy regimen(intravenous infusions of tislelizumab 200 mg on day 1, paclitaxel protein-bound 470 mg, and carboplatin 500 mg on day 1) after surgery for left upper lung squamous cell carcinoma, with 21 days as a treatment cycle. After more than half a month of medication in the 1st cycle, the patient developed multiple symmetrical purple red bruises on both lower limbs, which did not fade when pressed. The purple red bruising disappeared the next day after treatment with anti-allergic drugs. After 3 days of medication in the 3rd cycle, the patient developed a large number of scattered red papules on both lower limbs, protruding from the surface of the skin and accompanied by itching, a small number of red papules were scattered on both upper limbs and the face; after 15 days, the patient felt poor appetite; after 16 days, the patient experienced abdominal pain accompanied by vomiting and loose yellow stool. Laboratory tests showed a blood creatinine level of 204 μmol/L and occult blood in urine (+++). Pathological examination of skin tissue at the lesion site of the patient suggested IgA vasculitis (IgAV). After excluding other factors such as primary disease and infection, it was considered that the IgAV was probably related to tislelizumab. Tislelizumab was discontinued, anti-allergic and anti-inflammatory drugs, and glucocorticoid were given. After 2 weeks of treatments, the skin purpura gradually disappeared, and the abdominal pain and renal function indicators were improved. After fully aware of the risks, the patient was restarted tislelizumab immunotherapy combined with chemotherapy, and anti-allergic drugs were add at the same time. IgVA did not recur.
