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.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

The success of"New Medical Sciences"in higher education requires effective tools in evalua-ting students'performance in courses.Previously,we reported a teamwork(T),critique(C)and ap-preciation(A)(TCA)ideological and political model,a teaching model widely applied in Basic Medical courses.TCA is an abbreviation derived from Tricarboxylic Acid Cycle in Biochemistry as an analogy for nurturing the abilities of thinking and teamwork(T),critique(C)and appreciation(A),which hope-fully could provide students with moral norms for cognition,science and life.This paper further explores the tools to assess the educational outcomes of the TCA model,by which teachers can collect feedback and reflect on teaching quality and effectiveness.Addressing the challenges of individual differences in large classes,fragmented learning feedback,and the difficulty of measuring meta-cognition in educational evaluation,this study employs strategies of value-added assessment,matrix assessment and norm-transfer-able assessment to evaluate the TCA abilities from the aspects of thinking quality,thinking creativity,co-operation ability,iterative thinking,dialectical thinking and job responsibility.By modifying/using 18 e-valuation tools in Education and Psychology,we have established a rubric system composed of 30 primary indicators(with 11 newly designed,10 partly modified and 9 directly adopted),along with 49 secondary indicators and 98 tertiary indicators to enhance the feasibility of the evaluation process.This rubric sys-tem was applied to Biochemistry teaching among the five-year-program undergraduates at Air Force Medi-cal University.Specifically,thinking and teamwork are evaluated by creative works from"the magic bio-chemical-circle",while critiques are assessed in large classes under the guidance of basic and clinical teachers,coupled with appreciation measured by job responsibility in a task-driven virtual reality(VR)project.The results indicate that Biochemistry teaching not only accumulates knowledge in students,but also achieves the goals in nurturing values and cognition.The inclusion of creative performance evalua-tion,cooperative learning and clinical case studies,can enhance students'interpersonal skills,coopera-tion,quality of thinking,creative thinking,iterative thinking and dialectical thinking to varying degrees.TCA-based Biochemistry teaching has a long-lasting impact on character education,and is capable of in-ducing positive long-term changes in students'cognition and lifestyle.Taken together,with the help of this rubric system,teachers can promptly acknowledge the effectiveness of their teaching,thereby facilita-ting their teaching strategies.

As an important endocrine organ of human body,adipose tissue secrets a large amount of endocrine fac-tors that regulate a variety of physiological functions,and role of adiponectin in cardiovascular system is especially important.At the cellular and molecular level,adiponectin possesses profound anti-inflammatory,anti-oxidative and anti-apoptotic effects,which can reduce various pathogenic factors of cardiovascular diseases(CVD).In ad-vanced stage of CVD,the expression of adiponectin in adipose tissue as well as its circulating level compensatively increased.Therefore,adiponectin has a protective effect on the cardiovascular system,and increased adiponectin level may suggest severe CVD.In this review article,we systematically introduced the role of adiponectin in CVD and discussed its application prospects as a clinical biomarker.

Objective To improve and refine the relevant regulations and guiding principles of warnings on drug instructions and labels in China.Methods This paper sorted out the drug instructions of small molecule anti-tumor drugs listed by the U.S.Food and Drug Administration(FDA)from 2005 to 2022,included the drugs mentioned in the QT interval prolongation risk,analyzed the clinical research and QT research results,and sorted out the identification and warning rules of the instructions.Results A total of 35 drugs were included,4 drugs wrote the risk of QT interval prolongation in the black box warning,21 drugs were wrote in the warning and precautions position,6 drugs were wrote in the adverse reaction section,and 2 drugs were only described under clinical pharmacology section.According to the severity of the QT interval prolongation caused by the drug and whether there were serious clinical consequences,they were displayed in the warnings(black box warnings),precautions(warnings and precautions)and adverse reactions in the instructions.Conclusion The aim of this article is to provide a reference for the writing of QT risk warning information of the instructions of domestic drug production enterprises and regulatory departments.It is recommended to clarify the severity of drug safety and the location of the instructions in clinical research,and continue to carry out safety monitoring and update the instructions in time after listing.

Objective:To investigate the effects of different BMI classifications on rehabilitation outcomes and complications after total knee arthroplasty(TKA).Methods:Clinical data of 88 patients who underwent TKA in our hospital from January 2022 to June 2024 were retrospectively analyzed.According to the World Health Organization(WHO)BMI standards,patients were divided into normal weight group(18.5 ≤BMI＜24.9 kg/m2),overweight group(25.0≤BMI＜29.9 kg/m2),mild obesity group(30.0≤BMI＜34.9 kg/m2),and severe obesity group(BMI≥35.0 kg/m2).Baseline data,operation time,intraoperative blood loss,hospital stay,postoperative knee function scores,pain scores,range of motion(ROM),and incidence of complications were compared among groups.Results:With the increase of BMI,operation time was prolonged,intraoperative blood loss increased,and hospital stay extended,with statistically significant differences(P＜0.05).At 3-month and 6-month follow-ups,Knee Society Score(KSS)and Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)showed that functional recovery decreased with increasing BMI(P＜0.05).Regarding postoperative complications,the incidence of poor incision healing,infection,and deep vein thrombosis(DVT)in the obese groups was significantly higher than in the normal weight and overweight groups(P＜0.05).Conclusion:BMI is an important factor affecting rehabilitation outcomes and complications after TKA.Patients with high BMI have slower functional recovery and higher complication rates.For patients with high BMI,preoperative weight loss and individualized rehabilitation programs should be considered to improve TKA prognosis.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Parkinson's disease(PD)is one of the most common neurodegenerative disorders.Recent evidence implicates pyroptosis as one of the pathogenic mechanisms in central nervous system disorders,although its specific mechanisms remain unclear.In this study,SH-SY5Y cells were transfected with py-roptosis-related proteins GSDME full-length(GSDME-F)or GSDME-N terminal(GSDME-N)plasmids revealed that GSDME-N significantly reduced mitochondrial membrane potential(P＜0.0001).To inves-tigate the mechanism by which GSDME mediates mitochondrial dysfunction,Western blotting analysis demonstrated that transfection with GSDME-N plasmids significantly increased BAX expression and en-hanced its translocation to mitochondria in both HEK 293T and SH-SY5Y cells(P＜0.05).SH-SY5Y cells treated with varying concentrations of rotenone(ROT)exhibited GSDME cleavage,elevated BAX expression(P＜0.05),increased mitochondrial BAX aggregation(P＜0.05),and reduced mitochondrial membrane potential(P＜0.01),as confirmed by Western blotting and JC-1 staining.Concurrently,MTT assays assessing cell viability and lactate dehydrogenase(LDH)release assays indicated that ROT in-duced these processes prior to pyroptosis.Furthermore,in a ROT-induced mouse PD model,ROT trig-gered GSDME cleavage,enhanced BAX expression,caused dopaminergic neuronal damage,and induced motor deficits.In summary,this study demonstrates that GSDME-N exacerbates mitochondrial damage and increases cytotoxicity by upregulating BAX expression and facilitating its mitochondrial translocation.This study provides novel insights into the role of GSDME in PD pathogenesis and suggests potential avenues for therapeutic intervention.

Objective:To explore the correlation between smoking behavior of employees in heavy industry enterprises and risk factors for cardiovascular and cerebrovascular diseases.Methods:A cross-sectional study design was adopted. A questionnaire survey and physical examination data collection were conducted on employees of a heavy industry enterprise in Shaanxi Province using a cluster sampling method from March to April 2024. A total of 2 209 cases met the inclusion criteria. According to the smoking index (SI), participants were divided into a non-smoking group (SI=0, 1 316 cases), a low smoking group (SI400, 656 cases), and a high smoking group (SI≥400, 237 cases). According to the fagerstrom test for nicotine dependence (FTND) score, participants were divided into a non-dependence group (FTND=0, 1 316 cases), a mild dependence group (FTND=1-3, 623 cases), a moderate dependence group (FTND=4-6, 204 cases), and a severe dependence group (FTND≥7, 66 cases). Spearman rank correlation, univariate, and multivariate logistic regression analyses were used to compare differences in blood pressure, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, uric acid, homocysteine, and body mass index among the groups.Results:As the SI and FTND scores increased, blood pressure, low-density lipoprotein cholesterol, triglycerides, uric acid, and homocysteine all showed an increasing trend, while high-density lipoprotein cholesterol showed a decreasing trend (all P0.05). The systolic blood pressure, diastolic blood pressure, fasting blood glucose, low density lipoprotein cholesterol (LDL-C), triglycerides, serum uric acid, and homocysteine in the high smoking group were higher than those in the non-smoking group [(124.93±16.55) vs (122.32±16.62) mmHg (1 mmHg=0.133 kPa), (80.86±11.10) vs (76.18±11.63) mmHg, 5.58 vs 5.29 mmol/L, (3.13±0.65) vs (2.95±0.56) mmol/L, 1.70 vs 1.09 mmol/L, (336.80±69.94) vs (299.00±86.43) μmol/L, 14.20 vs 11.76 μmol/L, all P0.001], the high-smoking group had lower HDL cholesterol than the non-smoking group [(1.34±0.30) vs (1.39±0.27) mmol/L, P0.001], the systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, triglycerides, serum uric acid, and homocysteine in the severely dependent group were higher than those in the non-dependent group [(132.09±16.69 )vs (122.32±16.62) mmHg, (81.32±12.97) vs (76.18±11.63) mmHg, 5.61 vs 5.29 mmol/L, (4.98±0.91 )vs (4.70±0.88) mmol/L, (3.19±0.62) vs (2.95±0.56) mmol/L, 1.87 vs 1.09 mmol/L, (328.95±75.21) vs (299.03±86.43) μmol/L, 14.38 vs 11.76 μmol/L, all P0.05], and the high density lipoprotein cholesterol (HDL-C) in the severely dependent group was lower than that in the non-dependent group [(1.32±0.30) vs (1.39±0.27) mmol/L, P0.001]. Multivariate analysis showed that SI and degree of tobacco dependence (DTD), were significantly correlated with fasting blood glucose, triglycerides, and LDL cholesterol, but the effect size of SI was too small ( OR=1.001, 95% CI: 1.000-1.001, P=0.002, OR=1.001, 95% CI: 1.001-1.002, P0.001, OR=1.001, 95% CI: 1.000-1.001, P=0.032). Conclusions:Smoking behavior among employees in heavy industry enterprises is significantly correlated with risk factors for cardiovascular and cerebrovascular diseases. The degree of tobacco dependence is closely related to the risk of abnormal fasting blood glucose, low-density lipoprotein cholesterol, and triglycerides.

Objective:To evaluate the efficacy of transnasal high-flow humidified oxygen therapy in preventing hypoxemia in pediatric patients undergoing gastroscopy.Methods:In this prospective randomized controlled study, 226 pediatric patients, aged 6-12 yr, with a body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing painless gastroscopy at Women and Children′s Hospital of Qingdao University from February 2022 to August 2023, were selected and divided into 2 groups ( n=113 each) using the simple randomization method: normal nasal cannula oxygen therapy group (group N) and transnasal high-flow humidified oxygen therapy group (group H). Anesthesia was induced with intravenous nalbuphine hydrochloride 0.1 mg/kg and propofol 2 mg/kg, and gastroscopy was performed when the Modified Observer′s Assessment of Alertness/Sedation score reached 1. During the operation, group N inhaled oxygen 5 L/min through the nasal catheter; group H inhaled a mixture of air and oxygen through a transnasal high-flow humidified oxygen therapy system at 2 L·kg -1·min -1 (not exceeding 40 L/min), with FiO 2 of 40%. Primary outcomes were the occurrence of hypoxemia and the lowest SpO 2. Secondary outcomes included the requirement for airway interventions (jaw thrust, mask ventilation, endotracheal intubation) and incidence of adverse events (nasal dryness, laryngospasm, apnea, upper airway obstruction, abdominal distension, nausea and vomiting) and endoscopist′s satisfaction with the procedure. Results:A total of 214 patients finally completed the trial, with 106 in group N and 108 in group H. Compared with group N, the incidence of hypoxemia was significantly decreased (17.9% [19/106] versus 2.8% [3/108]), the lowest SpO 2 was increased, the requirement for jaw lifting interventions was reduced, the incidence of nasal dryness was decreased, and the degree of endoscopist′s satisfaction with the procedure was increased ( P<0.05), and no significant change was found in the other outcomes in group H ( P>0.05). Conclusions:Transnasal high-flow humidified oxygen therapy can effectively prevent hypoxemia and raise the safety of pediatric patients during the gastroscopy.
