At present, a number of human plasma-derived preparations containing von Willebrand factor(VWF) have been approved for market in foreign countries, and no such preparations have been listed in China, but clinical trials for such preparations have been prepared or carried out. This paper mainly draws on the research and development experience of blood-derived VWF in Europe and the United States, focuses on analyzing the technical requirements for quantitative detection and clinical trials of such preparations, and discusses the contents that should be paid attention to in clinical trials of domestic blood-derived VWF products for the treatment of von Willebrand disease(VWD), so as to provide reference for domestic VWF products to carry out related clinical trials.

Here, we report a previously unrecognized syndromic neurodevelopmental disorder associated with biallelic loss-of-function variants in the RBM42 gene. The patient is a 2-year-old female with severe central nervous system (CNS) abnormalities, hypotonia, hearing loss, congenital heart defects, and dysmorphic facial features. Familial whole-exome sequencing (WES) reveals that the patient has two compound heterozygous variants, c.304C>T (p.R102*) and c.1312G>A (p.A438T), in the RBM42 gene which encodes an integral component of splicing complex in the RNA-binding motif protein family. The p.A438T variant is in the RRM domain which impairs RBM42 protein stability in vivo. Additionally, p.A438T disrupts the interaction of RBM42 with hnRNP K, which is the causative gene for Au-Kline syndrome with overlapping disease characteristics seen in the index patient. The human R102* or A438T mutant protein failed to fully rescue the growth defects of RBM42 ortholog knockout ΔFgRbp1 in Fusarium while it was rescued by the wild-type (WT) human RBM42. A mouse model carrying Rbm42 compound heterozygous variants, c.280C>T (p.Q94*) and c.1306_1308delinsACA (p.A436T), demonstrated gross fetal developmental defects and most of the double mutant animals died by E13.5. RNA-seq data confirmed that Rbm42 was involved in neurological and myocardial functions with an essential role in alternative splicing (AS). Overall, we present clinical, genetic, and functional data to demonstrate that defects in RBM42 constitute the underlying etiology of a new neurodevelopmental disease which links the dysregulation of global AS to abnormal embryonic development.

ObjectiveTo investigate the clinical efficacy of Huangqi injection combined with Buzhong Yiqi acupuncture in the treatment of chronic fatigue syndrome （CFS） with Qi deficiency and its effects on TCM syndromes， fatigue symptoms， serum superoxide dismutase （SOD）， malondialdehyde （MDA）， and oxidized low-density lipoprotein （ox-LDL） levels. MethodA total of 200 patients with CFS of Qi deficiency were randomly divided into a control group （100 cases） and an observation group （100 cases）. The control group was treated with vitamin B compounds， and the observation group was treated with Huangqi injection combined with Buzhong Yiqi acupuncture for two weeks. The scores of TCM syndromes， fatigue symptoms， levels of serum SOD， MDA， and ox-LDL and the incidence of adverse reactions were observed and compared before and after treatment in two groups. ResultAfter treatment， the total effective rate of the control group was 54.34% （50/92）， while that of the observation group was 88.54% （85/96）. The total effective rate of the observation group was higher than that of the control group （χ²=27.13，P<0.05）. Compared with those in the two groups before treatment， scores of fatigue self-assessment scale （FSAS）， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the two groups after treatment were significantly decreased （P<0.05）. After treatment， scores of FSAS， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， TCM syndrome scores in the two groups after treatment were significantly decreased （P<0.05）. After treatment， TCM syndrome scores in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， MDA levels in the two groups were significantly decreased （P<0.05）， ox-LDL levels in the observation group were significantly decreased （P<0.05）， and SOD levels were significantly increased （P<0.05）. After treatment， compared with those in the control group， the serum MDA and ox-LDL levels in the observation group were significantly decreased （P<0.05）， and the serum SOD was significantly increased （P<0.05）. No serious adverse events or adverse reactions occurred during this clinical trial. ConclusionHuangqi injection combined with Buzhong Yiqi acupuncture has a good clinical curative effect in the treatment of CFS with Qi deficiency， which can effectively improve the fatigue symptoms of patients， increase the level of SOD， and reduce the level of serum MDA and ox-LDL. It is related to the production of antioxidants， inhibiting the production of lipid peroxides， and improving the body's ability to resist oxidative stress.

Based on WANG Xugao's “thirty methods of treating the liver”， it is believed that the occurrence and development of childhood tic disorders follow the dynamic progression from liver qi disease to liver fire disease and then liver wind disease. The basic pathogenesis of three stages are characterized by binding constraint of liver qi， liver fire hyperactivity， and internal stirring of liver wind. Moreover， liver-blood deficiency and stagnation， and malnutrition of liver yin as the main point in terms of the imbalance of liver qi， blood， yin， and yang should be considered， as well as the imbalance relationship of the five zang organs such as the involvement of other organs and the gradually reach of the other organs. Guided by the principles of “thirty methods of treating the liver”， the treatment of tic disorders in liver qi stage should focus on soothing the liver and rectifying qi， soothing the liver and unblocking the collaterals， using Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散）. The treatment of tic disorders in liver fire stage involves clearing， draining and resolving liver heat， using Longdan Xiegan Decoction （龙胆泻肝汤）， Xieqing Pill （泻青丸）， Danggui Longhui Pill （当归龙荟丸）， and Huagan Decoction （化肝煎）. The treatment of tic disorders in liver wind stage involves extinguishing wind and subduing yang， using Lingjiao Gouteng Decoction （羚角钩藤汤） and Liuwei Dihuang Pill （六味地黄丸）. Throughout the treatment process， attention should be paid to harmonizing the liver's qi， blood， yin， and yang， as well as addressing the pathology of other organs.

Objective:To investigate the acute gastrointestinal injury (AGI) in patients with extracorporeal membrane oxygenation (ECMO) at the early stage of operation and its influencing factors.Methods:A total of 70 patients with ECMO who were hospitalized in the Emergency Care Unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed, and a total of 70 patients with ECMO who were hospitalized in the emergency care unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed. According to the 2012 guidelines of the European Society of Intensive Care Medicine on the classification of acute gastrointestinal injury in critically ill patients, the patients were divided into AGI group and non-AGI group. The incidence of acute gastrointestinal injury in the early stage was statistically analyzed, and the results of blood gas analysis during ECMO loading and ECMO parameters, hemodynamic indexes and biochemical indexes after ECMO transfer were statistically analyzed. To explore the influencing factors and independent risk factors of AGI in the early stage. In addition, 70 patients were divided into successful group and non-successful group according to whether they were successfully withdrawn. The occurrence of acute gastrointestinal injury between the two groups was compared, and the effect of acute gastrointestinal injury on ECMO patients was analyzed.Results:Among the 70 ECMO patients, the incidence of early AGI was 71.43% (50 cases), and the components of AGI Ⅰ, Ⅱ, Ⅲ and Ⅳ were 18.57% (13 cases), 41.43% (29 cases), 11.43% (8 cases) and 0% (0 cases), respectively. ① Univariate analysis showed that systolic blood pressure, diastolic blood pressure, mean arterial pressure (MAP), vasoactive drug index (VIS), pH, lactic acid and BMI were significantly different between AGI group and non-AGI group when ECMO was used ( P < 0.05). Logistic binary regression analysis showed that BMI was an independent risk factor for early AGI in ECMO patients (ROC area 0.657, 95% confidence interval 0.522-0.791 ( P < 0.05), and Yoden index 0.15). (3) The AGI composition ratio of the unsuccessful group was higher than that of the unsuccessful group ( P < 0.05). Conclusions:Patients with ECMO have a high incidence of AGI in the early stage, mainly occurring in grade I and Ⅱ. Systolic blood pressure, diastolic blood pressure, MAP, VIS, pH, lactic acid and BMI when ECMO is put on are influential factors for the early development of AGI in ECMO patients, among which BMI is an independent risk factor for the early development of AGI in ECMO patients. The occurrence of AGI reduces the probability of successful withdrawal in ECMO patients.

Objective:To investigate the recovery of renal function and its influencing factors in patients receiving extracorporeal membrane oxygenation (ECMO) support and complicated with acute kidney injury(AKI).Methods:This was a retrospective observational study. The clinical data of patients with ECMO support and AKI admitted to the Emergency intensive care unit of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2019 to December 2021 were collected. The patients were divided into renal function recovery group and renal function non-recovery group according to the recovery of renal function after 28 days of ECMO. With renal function non-recovery at 28 days as the end point of the study, and the variables with significant differences in baseline were selected for stepwise backward regression to determine the independent risk factors. The receiver operator characteristic (ROC) curve was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic value of independent risk factors.Results:A total of 40 patients were enrolled, of which 28 patients (70%) had recovery of renal function, and 12 patients (30%) did not have recovery of renal function. Stepwise backward multivariate logistic regression analysis showed that lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function ( OR = 1.380, 95% CI: 1.096-1.738, P = 0.006). The ROC curve showed that the AUC and 95% CI were 0.863 (0.751-0.975), the sensitivity was 100%, and the specificity was 75%. Conclusion:Lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function on 28 days after ECMO initiation among patients undergoing ECMO support complicated with AKI. Lactate has a high predictive value for the non-recovery of renal function.

Objective:To evaluate the role of lactate dehydrogenase in diabetic neuropathic pain (DNP) and the relationship with peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) in mice.Methods:SPF-grade healthy male C57BL/6J mice, aged 6-8 weeks, weighing 18-22 g, were used to establish diabetes mellitus model by intraperitoneal injection of streptozotocin (STZ) 120 mg/kg. Twenty-four mice with diabetes mellitus were divided into 2 groups ( n=12 each) using a random number table method: DNP group and DNP + oxamate group (OXA group). Another 12 SPF-grade healthy male C57BL/6J mice were selected as control group (C group). In OXA group, oxamate 750 mg/kg was intraperitoneally injected once a day for 28 consecutive days. The equal volume of normal saline was given instead in C group and DNP group. The mechanical paw withdrawal threshold (MWT), blood glucose and body weight were measured at 3 days before STZ injection and at 1, 2, 3 and 4 weeks after STZ injection (T 0-4). After the last behavioural test was completed, blood samples were collected from the posterior orbits of anesthetized mice for determination of serum lactate concentrations. The animals were then sacrificed and the tissues from the prefrontal cortex of the brain were taken for determination of lactate content, mitochondrial membrane potential (by the JC-1), content of reactive oxygen species (ROS) (using dihydroethidium probes), and level of histone lactylation and expression of PGC-1α (by Western blot). Results:Compared with C group, the MWT was significantly decreased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were increased, the mitochondrial membrane potential was decreased, and the expression of PGC-1α was down-regulated in DNP and OXA groups ( P<0.05). Compared with DNP group, no significant change was found in blood glucose and body weight ( P>0.05), the MWT was significantly increased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were decreased, the mitochondrial membrane potential was increased, and the expression of PGC-1α was up-regulated in OXA group ( P<0.05). Conclusions:Lactate dehydrogenase promotes the development of DNP, and the mechanism is related to promotion of increase in histone lactfication and down-regulation of PGC-1α expression in the prefrontal cortex of mice.

Objective:To evaluate the association between preoperative serum β 2-microglobulin (β 2MG) concentrations and postoperative delirium (POD) in elderly patients. Methods:The study selected patients who underwent knee or hip arthroplasty under spinal-epidural anesthesia on an elective basis at Qingdao Municipal Hospital from May 2021 to November 2022. The patients were divided into a POD group and a non-POD group based on the occurrence of POD. The study was conducted as part of the Perioperative Neurocognitive Impairment and Biomarkers Lifestyle Cohort, which was a nested case-control study. The study collected baseline data from two groups of patients and analyzed the differences between them. Logistic regression was used to identify the risk factors for POD. The stability of the regression model was tested using sensitivity analysis. The mediation model was used to examine whether cerebrospinal fluid (CSF) biomarkers mediated the relationship between β 2MG and POD. The receiver operating characteristic curve was drawn and the area under the curve was calculated to evaluate the accuracy of preoperative β 2MG concentrations and CSF biomarker concentration in predicting POD. Results:There were 57 cases in POD group and 449 cases in non-POD group. The results of logistic regression analysis showed that the increased β 2MG and CSF total tau protein (t-tau) concentrations were risk factors for POD, and the increased CSF β-amyloid 42 concentration was a protective factor for POD after adjustment for multiple confounders such as age, gender, education, Mini-Mental State Examination, history of hypertension and infusion volume ( P<0.05). The results of mediation analysis showed that the serum β 2MG′s effect on POD was partly mediated by t-tau (18.1%). The results of the receiver operating characteristic curve showed that the area under the curve of the β 2MG concentration combined with the CSF biomarker concentration was 0.742. Conclusions:Elevated preoperative serum β 2MG concentration is a risk factor for POD in elderly patients, and the relationship may be partly mediated by CSF t-tau.
