To explore the role of the mutations G38R and D40G of Annexin A11 (ANXA11) in the onset of amyotrophic lateral sclerosis (ALS).
 Methods: The plasmids expressing ANXA11 wild type protein, ANXA11 G38R protein and ANXA11 D40G protein were constructed, respectively. The recombinant plasmids were then transfected into HEK293 cells respectively followed by cycloheximide (CHX) treatment for 0, 2, 4 and 8 h. The protein expressions of ANXA11 wild type, ANXA11 G38R and ANXA11 D40G mutations were determined by Western blot. Gray analysis by Image J was performed to compare the half-life of each protein. The NSC-34 cell lines constantly expressing ANXA11 wild type protein, ANXA11 G38R protein and ANXA11 D40G protein were established. The cells were treated with NP-40 lysis buffer to examine the protein solubility by Western blot.
 Results: Both ANXA11 G38R protein and ANXA11 D40G protein showed a shorter half-life than ANXA11 wild type protein (P<0.05), while there was no difference between ANXA11 G38R protein and ANXA11 D40G protein (P>0.05). There was no visible insoluble substance in the NP-40 lysates for ANXA11 wild type protein, ANXA11 G38R protein and ANXA11 D40G protein.
 Conclusion: G38R and D40G mutations reduce the stability of ANXA11 protein. G38R and D40G mutations do not alter ANXA11 solubility.

Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disease affecting the upper and lower motor neurons. It is characterized by progressive muscle weakness, atrophy and ultimate death due to dysphagia and dyspnea. There are many causes of ALS, among which the genetic factors show great relevance. Imbalance of protein homeostasis in neurons, prion-like proliferation and propagation of abnormal proteins, mitochondrial dysfunction, glutamate mediated excitotoxicity, and intraneuronal substance transport disorders are recognized as the pathogenesis.The study on gene mutation related to pathogenesis will bridge the molecular and cellular research of ALS, which can deepen the understanding of the occurrence and development of ALS and the role of gene mutation in ALS, and provide new ideas and enlightenment for the treatment of ALS.

OBJECTIVE To analyze the medication reconciliation for the inpatients in cardiovascular medicine department ，to provide reference for the establishment of working mode of clinical pharmacists in the department of cardiovascular medicine and to provide a basis for clinical pharmacists and community pharmacists developing pharmaceutical care for patients after transfering to community health center. METHODS From October 2020 to September 2021，newly admitted or newly transferred inpatients with chronic disease were selected from Shiyan People ’s Hospital of Shenzhen Bao ’an District. Medication reconciliation was conducted by clinical pharmacists after pharmaceutical consultation. According to the Pharmaceutical Care Network Europe （PCNE） classification system V 9.1，the existing drug-related problems （DRPs）were classified and summarized. The effectiveness and safety evaluation，medication education and other measures were provided ，and the acceptance of intervention was analyzed at the same time. RESULTS A total of 100 patients were included ，including 54 males and 46 females. The average age was （60.21±9.69） years，the average number of chronic diseases was （2.84±0.83），and the median number of drugs was 5.00. Among them ，110 treatment drug deviations were found in 74 patients，involving 10 categories and 61 drugs. Top three drugs in the list of accumulative drug deviation were cardiovascular system drugs （35 deviations），digestive medicine drugs （16 deviations）and endocrine system drugs （15 deviations）. The above treatment drug deviation may cause 122 DRPs， mainly “treatment effectiveness”problems（74 DRPs），and the causes were “inappropriate medication time ormedication interval ”（32 DRPs）， followed by “inappropriate drug combination ”（10 DRPs）. Interventions to DRPs mainly concentrated on patient level ，drug level （58）and doctor level （58），155 of which （84.70％）were fully accepted and implemented. CONCLUSIONS Some patients have a weak awareness of medications according to doctor ’s advice；drug reconciliation led by clinical pharma- cists at admission can fully understand the potential drug problems of patients ，and help doctors improve the drug compliance of patients and ensure their medication safety .
