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.

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.

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.

BACKGROUND:Currently,there have been studies on the regulatory mechanism of lncRNA\miRNA\mRNA co-expression network on the occurrence and development of osteoarthritis.Our research group has screened qualified NONHSAT248596.1 and miR-146a-5p through the database in the previous stage,but the corresponding in vivo experiments to verify the above regulatory mechanisms are still lacking. OBJECTIVE:To explore the role of NONHSAT248596.1 in regulating competitive endogenous RNA of miR-146a-5p in cartilage degeneration mediated by stromal cell derived factor type 1/chemokine receptor 4 axis in vivo. METHODS:The models of osteoarthritis were established in 36 New Zealand rabbits by injecting stromal cell derived factor 1 solution into the knee joint of the right hind limb.According to the random number table method,they were divided into four groups.lncRNA group,miRNA group,ceRNA group and control group were injected with lentivirus vector overexpressing NONHSAT248596.1,lentivirus vector overexpressing miR-146a-5p,lentivirus vector overexpressing miR-146a-5p+NONHSAT248596.1 and empty lentivirus vector into the molded knee joint,respectively.At 4,8 and 12 weeks of modeling,cartilage tissues and subchondral bone tissues of the knee joint were taken for relevant detection. RESULTS AND CONCLUSION:Hematoxylin-eosin staining and safranin fast green staining showed different degrees of degeneration in the four groups.At 4 weeks,the cartilage tissue of the lncRNA group showed swelling of chondrocytes,loss of cell polarity,destruction of extracellular matrix,surface erosion,fracture formation and partial or full layer loss of cartilage tissue.The degree of cartilage injury was gradually aggravated with time.The progression of articular cartilage inflammation in the miRNA group was the slowest among the four groups.qRT-PCR showed that at the same time point,mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in cartilage tissue of the lncRNA group were higher than those of the other three groups(P＜0.05).The mRNA expression levels of miR-146a-5p,aggrecan and type Ⅱ collagen were lower than those of the other three groups(P＜0.05).The mRNA expression levels of NONHSAT248596.1,chemokine receptor 4,matrix metalloproteinase 3,matrix metalloproteinase 9 and matrix metalloproteinase 13 in the miRNA group were lower than those in the ceRNA group and control group at 8 and 12 weeks after the model construction(P＜0.05).The mRNA expressions of miR-146a-5p,aggrecan and type Ⅱ collagen were higher than those of the ceRNA group and control group(P＜0.05).Western blot assay showed that at the same time point,the expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the lncRNA group were always lower than those of the other three groups(P＜0.05).The expression levels of aggrecan and type Ⅱ collagen in cartilage tissue of the miRNA group at 8 and 12 weeks after modeling were higher than those of the ceRNA group and control group(P＜0.05).The results showed that miR-146a-5p,as the target of NONHSAT248596.1,could be inhibited by the effect of its ceRNA.After acting on miR-146a-5p,NONHSAT248596.1 regulates the stromal cell derived factor type 1/chemokine receptor 4 axis to affect the expression of matrix metalloprotein,type Ⅱ collagen,and aggrecan in osteoarthritis chondrocytes,resulting in the degradation of extracellular matrix and the loss of proteoglycan.

BACKGROUND:Bone marrow mesenchymal stem cells have been widely used to treat neurological diseases.However,due to limitations of the blood-brain barrier,low survival rate and differentiation rate of stem cells at damaged sites,the therapeutic effect is limited. OBJECTIVE:To investigate the effects of Shexiang Huangqi compound dripping pills on proliferation,migration and astrocyte differentiation of bone marrow mesenchymal stem cells. METHODS:Male SD rats were treated with Shexiang Huangqi compound dripping pills for 5 days after continuous gavage.Blood was collected from the abdominal aorta and serum was separated for later use.The effect of 5%,10%and 20%drug-containing serum on the proliferation of bone marrow mesenchymal stem cells was detected by CCK-8 assay.The effect of 10%drug-containing serum on lateral migration of bone marrow mesenchymal stem cells was observed by scratch test.Bone marrow mesenchymal stem cells were cultured in Transwell cells.The effects of 10%drug-containing serum on longitudinal migration of bone marrow mesenchymal stem cells were observed by crystal violet staining and DAPI nuclear staining.Differentiation of bone marrow mesenchymal stem cells into astrocytes was observed by inducing solution with 10%drug-containing serum or co-culture with astrocytes. RESULTS AND CONCLUSION:(1)10%and 20%drug-containing serum promoted cell proliferation more significantly on days 2 and 3,and there was no statistical difference between the two concentrations.(2)At 30 and 48 hours,bone marrow mesenchymal stem cell migration in 10%drug-containing serum group was significantly higher than that in the control group.(3)The number of bone marrow mesenchymal stem cells filtered through Transwell cells in 10%drug-containing serum group was higher than that in the control group.(4)10%drug-containing serum might promote the differentiation of bone marrow mesenchymal stem cells to astrocytes,but the differentiation effect was weak,and astrocytes might further promote the differentiation of bone marrow mesenchymal stem cells into astrocytes induced by drug-containing serum.(5)The results exhibited that the 10%drug-containing serum could promote the proliferation and migration of bone marrow mesenchymal stem cells in vitro.Co-culture with astrocytes may promote the differentiation of bone marrow mesenchymal stem cells towards astrocytes.
