Objective To explore the relationship between urinary activin A and neonatal hypoxic-ischemic encephalopathy(HIE).Methods 50 full-term neonatal with HIE were selected as the observation group,48 normal full-term neonatal in the same period were selected as the normal control group randomly.Within 7 days after birth,the observation group was divided into the group of 30 patients with mild HIE and the group of 20 patients with moderate and severe HIE,according to diagnostic criteria and clinical grading of neonatal HIE.The levels of urinary activin A in two groups after birth at different time(2,12,24,48,72h)was determined by using ELISA method.Results The levels of urinary activin A in moderate and severe HIE group was significantly higher than than in the normal control group(P＜0.01)and mild HIE group(P＜0.01);The levels of urinary activin A in the normal control group and mild HIE group showed no significant differences(P＞0.05).Urinary activin A level＞70 ng/L for the critical value to determine the occurrence of moderate and severe HIE,the sensitivity and specificity of 2 h urinary activin A levels were separately 86％ and 99％;The sensitivity and specificity of 12～72 h urinary activin A levels were separately 100％ and 98％.Conclusion The correlation between the level of urinary activin A and the severity of HIE was positive,the level of urinary activin A had a high degree of sensitivity and specificity for determine the incidence of moderate and severe HIE,it provided an important basis for diagnosis of moderate and severe HIE.

Objective To test the level of aquaporin-4 (AQP4) antibody and assess the frequency and specificity of AQP4 antibodies in patients with neuromyelitis optica spectrum disorders (NMOSDs).Methods One hundred and fifty-three patients with demyelinating disease of the central nervous system,admitted to our hospital from May 2007 to May 2012,were chosen in our study; of them,102 had NMOSDs; AQP4 antibodies in the sera of these 102 patients were detected by cell-based immunofluorescence assay (CBA); the distinctive features of NMOSDs by autoantibodies status (AQP4 antibody-positive or antibody-negative) were analyzed retrospectively.Results The sensitivity and specificity of CBA assay for detecting AQP4 antibodies were 83.3％ and 100％,respectively.In patients with positive AQP4 antibodies,the female one took 78.8％,while in patients with negative AQP4 antibodies,the female one only took 28.6％; significant difference was noted between the two (P=0.007); the patients with both AQP4 antibody-positive and other systemic autoimmune diseases showed higher expanded disability status scale scores at the disease onset (5.9±2.0) as compared with the patients only with AQP4 antibody-positive (4.2±1.9,t=3.806,P=0.033); AQP4 antibody deduced even lost during the remission stage,and immunosuppressant medicine could remove the AQP4 antibody.Conclusion Testing for AQP4 antibodies is helpful for the differential diagnosis between NMOSDs and multiple sclerosis,and also useful for predicting the relapse and treating of NMOSDs.

ObjectiveTo evaluate the clinical effectiveness and safety of acupuncture with manipulation for lumbar disc herniation in remission period. MethodsOne hundred and four patients with lumbar disc herniation in remission were randomly divided into a treatment group and a control group， with 52 cases in each group. Treatment group applied acupuncture with manipulation of pointing， pulling， and shaking. Acupoints were selected as lumbar Jiaji （EX-B2， bilateral）， Ashi point， Shenshu （BL 23， bilateral）， Huantiao （GB 30， bilateral）， Weizhong （BL 40， opposite side of the affected area）， Chengshan （BL 57， opposite side of the affected area）. The control group applied lumbar traction plus acupoint ultrasonic pulse penetration therapy （acupoints selection same as the treatment group）； 20 minutes each time， 3 times a week， a total of 3 weeks for both groups. The primary outcome was the improvement rate of lumbar disc herniation symptoms and signs， which was calculated at 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up， respectively； the secondary outcome were the Japanese Orthopaedic Association （JOA） scores， Visual Analogue Scale （VAS） scores， and Oswestry Disability Index （ODI） scores （including ODI total scores， sitting scores and standing scores）， which were evaluated before treatment， 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up； clinical effectiveness was assessed at 3 months follow-up； and the occurrence of adverse events in the participants， as well as blood routine， urine routine， stool routine， and electrocardiograms before and after the treatment were recorded to evaluate safety. ResultsTwo patients from each group fell out， and 50 patients of each group were included in the outcome analysis ultimately. The scores of lumbar disc herniation symptoms and signs improved more in the treatment group than in the control group at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up （P＜0.01）. The JOA scores of participants in both groups at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up were higher than those before treatment in the same group， and the VAS scores， ODI total scores， ODI sitting scores and standing scores were significantly lower than those before treatment in the same group （P＜0.05）， and the JOA scores of patients in the treatment group were higher than those of the control group at all time points， and the VAS scores， ODI total scores， ODI sitting scores and standing score were lower than those of the control group （P＜0.05）. At the 3 months follow-up， the excellent rate of the treatment group was 70.00% （35/50） better than that of the control group， which was 50.00% （25/50） （P＜0.05）. There were no abnormalities in blood， urine， stool routines and electrocardiograms before and after treatment in both groups， and no adverse events occurred. ConclusionAcupuncture with manipulation of pointing， pulling， and shaking for treating patients with lumbar disc herniation in remission has a better safety on pain relief and improving quality of life， and the effectiveness is better than lumbar traction plus acupoint ultrasonic pulse penetration therapy.

ObjectiveTo observe the therapeutic effects of Qishao Huoxue prescription on patients with lumbar disc herniation due to Qi stagnation and blood stasis and the effects of this prescription on hemorheological parameters and serum levels of inflammatory mediators. MethodA total of 86 patients with lumbar disc herniation due to Qi stagnation and blood stasis treated in the Wangjing Hospital of China Academy of Chinese Medical Sciences from January 2023 to February 2024 were selected and assigned according to the random number table into observation and control groups （n=43）. Patients in both groups received lumbar traction treatment. In addition， the observation group was orally treated with Qishao Huoxue prescription and the control group with celebrex for 3 weeks. The visual analogue scale （VAS） score， Oswestry disabilitiy index （ODI） score， 12-item Short-Form Survey （SF-12） score， traditional Chinese medicine （TCM） symptom score， hemorheological parameters ［whole blood high shear viscosity， middle shear viscosity， low shear viscosity， plasma viscosity （PV）， and fibrinogen （FIB）］， and the serum levels of inflammatory mediators ［tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and transforming growth factor-β₁ （TGF-β₁）］ were determined before and after treatment. In addition， the clinical efficacy and adverse reactions were observed and compared between the two groups. ResultAfter treatment， both groups showed declined VAS， ODI， and TCM symptom scores （P<0.05）， increased SF-12 physical component summary （PCS） and mental component summary （MCS） scores （P<0.05）. After treatment， the whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， and FIB decreased in the observation group （P<0.05）， while they did not show significant variations in the control group. After treatment， both groups of patients showed reductions in TNF-α， IL-6， and IL-1β levels and an elevation in the TGF-β₁ level （P<0.05）. Compared with the control group after treatment， the observation group showed decreases in VAS， ODI， TCM symptom scores and main symptom scores （P<0.05）， no significant differences in the secondary symptom scores， increased PCS and MCS scores （P<0.05）. The observation group outperformed the control group in terms of recovering whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， FIB， TNF-α， IL-6， IL-1β， and TGF-β₁ （P<0.05）. The total response rate in the observation group was 97.5% （40/41）， which was higher than that （88.1%， 37/42） in the control group （P<0.05）. No serious adverse reaction was observed in the two groups during the observation period. One case in the observation group showed subcutaneous bruising on the lower limbs， which gradually disappeared after withdrawal. ConclusionQishao Huoxue prescription demonstrated definite effect in treating lumbar disc herniation due to qi stagnation and blood stasis by recovering hemorheological parameters and inhibiting the expression of inflammatory mediators in the serum without inducing adverse reactions. It is worth applying in clinical practice.

Mitophagy is an essential intracellular process that eliminates dysfunctional mitochondria and maintains cellular homeostasis. Mitophagy is regulated by the post-translational modification of mitophagy receptors. Fun14 domain-containing protein 1 (FUNDC1) was reported to be a new receptor for hypoxia-induced mitophagy in mammalian cells and interact with microtubule-associated protein light chain 3 beta (LC3B) through its LC3 interaction region (LIR). Moreover, the phosphorylation modification of FUNDC1 affects its binding affinity for LC3B and regulates selective mitophagy. However, the structural basis of this regulation mechanism remains unclear. Here, we present the crystal structure of LC3B in complex with a FUNDC1 LIR peptide phosphorylated at Ser17 (pS), demonstrating the key residues of LC3B for the specific recognition of the phosphorylated or dephosphorylated FUNDC1. Intriguingly, the side chain of LC3B Lys49 shifts remarkably and forms a hydrogen bond and electrostatic interaction with the phosphate group of FUNDC1 pS. Alternatively, phosphorylated Tyr18 (pY) and Ser13 (pS) in FUNDC1 significantly obstruct their interaction with the hydrophobic pocket and Arg10 of LC3B, respectively. Structural observations are further validated by mutation and isothermal titration calorimetry (ITC) assays. Therefore, our structural and biochemical results reveal a working model for the specific recognition of FUNDC1 by LC3B and imply that the reversible phosphorylation modification of mitophagy receptors may be a switch for selective mitophagy.
