The implementation of the "Regulations on Organ Donation and Transplantation" (hereinafter referred to as the new "Regulations") and supporting documents has laid a solid foundation for improving the organ donation and transplantation work system in accordance with laws and regulations. In order to better publicize, implement, and carry out the new "Regulations" and supporting documents, and in response to the problems and challenges encountered in actual work, combined with the development of the national human organ donation and transplantation work system and the national work on determination of brain death, this article analyzes and discusses the construction of hospitals' organ donation and transplantation work systems and the systematic multidisciplinary collaboration mechanism for organ donation, as well as several issues that need attention by the ethics committees for organ transplantation. The aim is to provide references for the construction of ethics committees for organ transplantation in China and to promote the continuous and healthy development of China's organ donation and transplantation cause.

Based on his extensive clinical experience and the team's mechanistic research, Professor XU Nenggui has proposed the academic concept that "the governor vessel governs the brain and treats cerebral viscus diseases", and established a novel acupuncture approach for encephalopathy treatment centered on the integrated theory of "governor vessel-brain-mind", and developed a staged acupuncture protocol of "governor vessel regulating spirit" for ischemic stroke. This article introduces the academic features of this method in treating post-stroke dysphagia from four aspects: theoretical framework, treatment principles and point selection, mechanistic research, and clinical case studies. In clinical application, the method emphasizes syndrome differentiation based on meridians, harmonization between the conception and governor vessels; precise acupoint selection to treat both form and spirit; stage-specific differentiation with targeted needling. Furthermore, Professor XU integrates basic research with clinical practice, focusing on the neurobiological mechanisms underlying the efficacy of acupuncture in treating post-stroke dysphagia.

BACKGROUND:Percutaneous vertebroplasty has become the main treatment method for osteoporotic vertebral compression fractures due to its advantages of convenient operation and low trauma.However,the optimal bone cement-vertebral volume ratio has not been determined. OBJECTIVE:To investigate the effect of bone cement-vertebral volume ratio on percutaneous vertebroplasty for osteoporotic vertebral compression fractures. METHODS:The clinical data of 100 patients with single-stage osteoporotic vertebral compression fractures admitted to Xinjiang Bazhou People's Hospital from July 2019 to July 2022 were retrospectively analyzed.All patients received percutaneous vertebroplasty.According to the bone cement-vertebral volume ratio,they were divided into the low volume group(15%≤ratio≤20%)and the high volume group(20%0.05).The vertebral anterior margin height in the low volume group was lower than that in the high volume group at 3 days and 1 year after surgery(P<0.05).The Cobb angle of the injured vertebrae in the low volume group was higher than that in the high volume group at 3 days and 1 year after surgery(P<0.05).(2)There were 10 H-type and 40 O-type bone cement distributions in the low volume group.There were 36 H-type and 14 O-type bone cement distributions in the high volume group,and there was no significant difference in bone cement distributions between the two groups(P<0.05).The bone cement leakage rate in the high volume group and low volume group was 10%and 6%,respectively.(3)It is indicated that both low and high bone cement-vertebral volume ratios can improve postoperative pain and functional dysfunction,but high bone cement-vertebral volume ratio can improve the morphological recovery of injured vertebral,which may be related to the fact that the distribution of bone cement in this group is more H-type.

Objective To explore the application value of modified prophylactic ileostomy in natural orifice specimen extraction surgery(NOSES)for patients with mid-low rectal cancer.Methods We retrospectively analyzed 63 patients who received prophylactic ileostomy in NOSES for mid-low rectal cancer in our hospital from September 2017 to May 2023.The patients were divided into the observation group(those who received modified ileostomy,n=31)and the control group(those who received conventional loop ileostomy,n=32)according to different ostomy methods.The operation time of ostomy,operation time of ostomy reversal surgery,early-stage complications(stoma leakage,peristomal dermatitis,stoma pain,peristomal trocar hole infection,stoma bleeding,stoma ischaemic necrosis,stoma oedema,peristoma skin-mucosal separation and stoma proximal bowel obstruction)and long-stage complications(stoma stenosis,stoma retraction,stoma prolapse,parastomal hernia),tumor recurrence and death of the two groups were compared and analyzed.Results Both prophylactic ileostomy and ostomy reversal surgery were successfully completed in all the 63 cases.The operation time of ostomy in the observation group was 7(6-8)min,which was significantly shorter than that of 23(21-24)min in the control group(Z=-6.853,P=0.000),and the operation time of ostomy reversal surgery in the observation group was(63.2±5.7)min,which was significantly shorter than(93.5±4.7)min in the control group(t=-23.109,P=0.000).Neither stoma bleeding nor stoma ischaemic necrosis were observed in both groups.The incidence of stoma pain in the observation group was lower than that in the control group[6.4％(2/31)vs.65.6％(21/32),x2=21.766,P=0.000].The incidence of peristomal incision infection in the observation group was lower than that in the control group[0％(0/31)vs.53.1％(17/32),P=0.000].There was no stoma stenosis in both groups.There were 3 cases of parastomal hernia,1 case in the observation group and 2 cases in the control group,the difference of the incidence being not statistically significant(P=1.000).There was 1 case of stoma retraction and 1 case of stoma prolapse in the control group.All the 5 cases with complications received prompt treatment in the second ostomy reversal surgery.Follow-up visits for 6-60 months in the 63 cases showed no tumor recurrence or death.Conclusion Modified prophylactic ileostomy in NOSES for patients with mid-low rectal cancer is safe,feasible,and easy to operate,having certain practicality and promotion value.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons (MNs) with large unmet medical needs. Multiple pathological mechanisms are considered to contribute to the progression of ALS, including neuronal oxidative stress and mitochondrial dysfunction. Honokiol (HNK) has been reported to exert therapeutic effects in several neurologic disease models including ischemia stroke, Alzheimer's disease and Parkinson's disease. Here we found that honokiol also exhibited protective effects in ALS disease models both in vitro and in vivo. Honokiol improved the viability of NSC-34 motor neuron-like cells that expressed the mutant G93A SOD1 proteins (SOD1-G93A cells for short). Mechanistical studies revealed that honokiol alleviated cellular oxidative stress by enhancing glutathione (GSH) synthesis and activating the nuclear factor erythroid 2-related factor 2 (NRF2)-antioxidant response element (ARE) pathway. Also, honokiol improved both mitochondrial function and morphology via fine-tuning mitochondrial dynamics in SOD1-G93A cells. Importantly, honokiol extended the lifespan of the SOD1-G93A transgenic mice and improved the motor function. The improvement of antioxidant capacity and mitochondrial function was further confirmed in the spinal cord and gastrocnemius muscle in mice. Overall, honokiol showed promising preclinical potential as a multiple target drug for ALS treatment.

Organ transplantation is an effective treatment for end-stage organ failure. The shortage of donors severely restricts the development of organ transplantation, which is also an unresolved challenge in the reform of organ transplantation in China. To alleviate the shortage of donors, western countries have established the working mechanism of systematic multi-department collaboration (SMDC), which has significantly elevated the level of organ donation by promoting systematic collaboration among relevant departments in all aspects of organ donation. At present, organ donation and transplantation in China have entered the new stage of high-quality development, whereas the level of organ donation remains to be further improved. In this article, the concept of SMDC, the procedures and departments related to SMDC, and the international experience of SMDC were illustrated. Besides, suggestions and proposals were delivered for implementing SMDC in China and constantly developing and modifying the Chinese model of organ donation catering to national conditions.

Ankylosing spondylitis (AS) is a chronic inflammatory disease mainly affecting the sacroiliac joints, spine and peripheral joints. In China, standardized diagnosis and treatment of AS is still to be popularized. Based on the evidence and guidelines from China and other countries, Chinese Rheumatology Association developed standardization of diagnosis and treatment of AS. The purposes are: (1) to standardize the diagnosis and evaluation of AS; (2) to promote rational use of non-steroidal anti-inflammatory drugs, biological as well as traditional disease modifying anti-rheumatic drugs, so as to improve the patient′s quality of life.

Objective:To explore the value of renal injury marker protein in early diagnosis of acute kidney injury (AKI) in burn patients with delayed resuscitation.Methods:The retrospective case-control research was conducted. Forty-three burn patients with delayed resuscitation (27 males and 16 females, with age of 18-75 (35±3) years)who were admitted to Zhengzhou First People′s Hospital from May 2018 to May 2020 met the inclusion criteria. The patients were divided into AKI group with 23 patients and non-AKI group with 20 patients according to whether AKI occurred within 7 days after burns. The gender, age, deep partial-thickness burn area, full-thickness burn area, and acute physiology and chronic health evaluation Ⅱ of patients were compared between the two groups.The fluid supplement volume and serum creatinine at 12, 24, and 48 h after burn, serum albumin/fibrinogen ratio (AFR), urinary heat shock protein 70 (HSP70), tissue inhibitor of metalloproteinase-2 (TIMP-2)×insulin-like growth factor binding protein 7 (IGFBP-7), and neutrophil gelatinase associated lipocalin (NGAL)at 12, 24, 48, 72, 120, and 168 h after burn were detected.Data were statistically analyzed with Mann-Whitney U test, analysis of variance for repeated measurement, independent-samples t test, chi-square test and Bonferroni correction. The independent variable to predict the occurrence of AKI was screened by multi-factor logistic regression analysis. The receiver′s operating characteristic curve was drawn for predicting the occurrence of AKI in burn delayed resuscitation patients, and the area under the curve (AUC), the best threshold, and the sensitivity and specificity under the best threshold were calculated. Results:The gender, age, deep partial-thickness burn area, full-thickness burn area, acute physiology and chronic health evaluation Ⅱ of patients in two groups were similar ( χ2=1.98, t=1.98, 1.99, 1.99, 1.99, P>0.05). The fluid supplement volume of patients in AKI group at 24 and 48 h after burn was significantly less than that in non-AKI group ( t=15.37, 6.51, P<0.01). The serum creatinine of patients in AKI group at 12, 24, and 48 h after burn was significantly higher than that in non-AKI group ( Z=2.16, 5.62, 6.72, P<0.01). The serum AFR of patients in AKI group at 12, 24, 48, 72, 120, and 168 h after burn was significantly lower than that in non-AKI group ( t=16.14, 35.35, 19.60, 20.47, 30.20, 20.17, P<0.01). The levels of urinary HSP70 of patients in AKI group at 12, 24, 48, 72, 120, and 168 h after burn were (6.89±0.87), (6.42±0.73), (5.81±0.72), (5.17±0.56), (4.63±0.51), (3.89±0.51) μg/L, which were significantly higher than (3.89±0.75), (3.57±0.63), (2.66±0.41), (1.83±0.35), (1.48±0.19), (1.28±0.19) μg/L in non-AKI group ( t=12.00, 13.61, 17.39, 22.98, 26.34, 21.59, P<0.01). Urinary TIMP-2×IGFBP-7 and NGAL of patients in AKI group at 12, 24, 48, 72, 120, 168 h after burn were significantly higher than those in non-AKI group ( t=26.94, 101.11, 35.50, 66.89, 17.34, 14.30, 14.00, 13.78, 12.32, 14.80, 21.36, 22.62, P<0.01). Urinary HSP70 and serum AFR at 12 h after burn, urinary TIMP-2×IGFBP-7 and NGAL at 24 h after burn were included into multi-factor logistic regression analysis (odds ratio=2.42, 3.47, 7.52, 5.61, 95% confidence interval=1.99-2.95, 1.86-3.92, 2.87-9.68, 2.14-14.69, P<0.01). For 43 patients with burn delayed resuscitation, the AUC of receiver′s operating characteristic curve of serum AFR at 12 h after burn for predicting AKI was 0.739 (95% confidence interval=0.576-0.903), the optimal threshold was 9.90, the sensitivity was 82%, and the specificity was 90%. The AUC of urinary HSP70 at 12 h after burn was 0.990 (95% confidence interval=0.920-1.000), the optimal threshold was 1.40 μg/L, the sensitivity was 98%, and the specificity was 96%. The AUC of urinary TIMP-2×IGFBP-7 at 24 h after burn was 0.715 (95% confidence interval=0.512-0.890), the optimal threshold was 114.20 μg 2/L 2, the sensitivity was 91%, and the specificity was 95%. The AUC of urinary NGAL at 24 h after burn was 0.972 (95% confidence interval=0.860-1.000), the optimal threshold was 78 μg/L, the sensitivity was 95%, and the specificity was 96%. Conclusions:Urinary HSP70 and NGAL have higher value in early diagnosis of AKI in burn patients with delayed resuscitation.
