Alzheimer's disease is a common central neurodegenerative disease, mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear, and the western medicine currently used to treat Alzheimer's disease is only symptomatic, with a single pathway, limited efficacy, and many side effects. In recent years, with the deepening of research on Alzheimer's disease, the study and application of traditional Chinese medicine (TCM) in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation, oxidative stress, neuroinflammation, ferroptosis, mitochondrial dysfunction, neurogenesis and neurotransmission, and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years, so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with unknown etiology and limited therapeutic options. Activation of fibroblasts is a prominent feature of pulmonary fibrosis. Here we report that lncRNA DACH1 (dachshund homolog 1) is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis. LncDACH1 knockout mice develop spontaneous pulmonary fibrosis, whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation, collagen deposition and differentiation of mouse lung fibroblasts. Similarly, forced expression of LncDACH1 not only prevented bleomycin (BLM)-induced lung fibrosis, but also reversed established lung fibrosis in a BLM model. Mechanistically, LncDACH1 binding to the serine/arginine-rich splicing factor 1 (SRSF1) protein decreases its activity and inhibits the accumulation of Ctnnb1. Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts. Furthermore, loss of LncDACH1 promoted proliferation, differentiation, and extracellular matrix (ECM) deposition in mouse lung fibroblasts, whereas such effects were abolished by silencing of Ctnnb1. In addition, a conserved fragment of LncDACH1 alleviated hyperproliferation, ECM deposition and differentiation of MRC-5 cells driven by TGF-β1. Collectively, LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation, suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis.

Formins are widely distributed in eukaryotes such as fungi, plants and animals. They play crucial roles in regulating the polymerization of actin, coordinating the synergistic interactions between actin and microtubules, and determining cell growth and morphology. Unlike formins from fungi and animals, plant formins have been evolved into two plant-specific types. Generally, type Ⅱ formins are believed to regulate the polarized growth of cells, and type Ⅰ formins may regulate the cell expansion and division processes. Recent studies on the function of plant formins suggest it is inappropriate to classify the function of formins purely based on their structures. This review summarizes the domain organization of formins and their corresponding functions, as well as the underpinning mechanisms. Furthermore, the unsolved or unexplored issues along with future perspectives on plant formins are proposed and discussed.

Objective To investigate the effect of sevoflurane on blood pressure in patients with different ages and the optimal concen-tration of sevoflurane. Methods 60 patients underwent selective LC operation with conventional induction and sevoflurane maintenance were divided into three groups:the youth group (34 patients), the middle age group (20 patients) and the older age group (6 patients). The SBP, DBP, MAP, CETsev, number of patients, age of patients before induction and 10 min(T1), 20 min(T2), 30 min (T3), 60 min (T4) after induction were recorded. Results Fluctuate of blood pressure were in the normal range after anesthesia maintenance, and MAP were fluctuated within the range of ± 20% before induction. The age under different CETsev were of no significant difference in each time point (P>0. 05). The age composition ratio in different CETsev were of no significant difference in each time point (P>0. 05). As the time of anesthesia extended, the number of patients under 0% ~1%CETsev decreased from 35 to 11; the number of patients under 1% ~2%CETsev increased from 10 to 20;and the number of patients under 2% ~3%CETsev maintened in 14 approximately. Conclusion The effect of sevoflurane on blood pressure of different ages is approximate. 2% ~3% CETsev is the most optimal concentration during the main-tenance of anesthesia.

OBJECTIVE:To reduce the error rate of inventory in the automated pharmacy of our hospital. METHODS:Activi-ties were designed and implemented by the management method of quality control circles(QCC)-PDCA(Plan,Do,Check and Ac-tion)cycle. The reasons for the errors of inventory in the automated pharmacy were analyzed to investigate and implement counter-measures. Visible and invisible achievements were evaluated,and then standardized processes were made. RESULTS:The errors of inventory in the automated pharmacy mainly included those of drug dispensing,drug shelving,drug return sheet,automatic medi-cine dispensing machine and system. In view of the above reasons,relevant standards were formulated and performed,including the process of warehouse-out check and shelving of drugs,drug dispensing process for the automated pharmacy,the process of sec-ondary check,etc. After the implementation of the activities,the error rate of inventory in the automated pharmacy reduced from 9.17% to 3.77%,which was visible achievement;and the above-mentioned standardized processes could ensure continuous run-ning of PDCA cycle. The practice,sense of responsibility,communication and coordination of management members in PDCA cy-cle namely invisible achievements were improved to some extent. CONCLUSIONS:The management method of QCC-PDCA cycle is feasible in reduction of the error rate of inventory in the automated pharmacy,which can provide a reference for automated phar-macy management.

Background and objectiveEpidermal growth factor receptor (EGFR) and KARS must be detected mu-tation status before patients of lung cancer use targeted drugs. The aim of this study is to elucidate the signiifcance ofEGFR and KARS mutation in ifne needle aspiration (FNA) cytology suspension specimens of non-small cell lung carcinoma.Methods EGFR gene exons 18-21 andKARS codons 12, 13 of exons 2 were performed by Real-time PCR methods in ifne needle aspira-tion cytology suspension specimens of lymph nodes.Results 85 metastasis lymph nodes were detected in ifne needle aspira-tion cytology samples of lung cancer.EGFR mutation rate was 37.3%.KARS mutation rate was 7.2%. 19 formalin ifxed paraffn-embedded tissue specimens were available and match cytology specimens. Analysis ofEGFRmutation status in those samples revealed agreement with the results obtained in cytological samples (kappa=1.0). Clinical follow-up was available for 13 who presented with stage IV disease. Based on the identiifcation of such mutations, these patients received subsequent therapy with a TKI in clinic. We observed two cases complete remission (16.7%) and 8 cases partial remission (66.7%) and three had ongo-ing stable disease.ConclusionFine-needle aspiration cytology samples were detectedEGFR andKARS mutation. The meth-od which collects samples was easier, simple and convenient. This method has higher application value in clinical treatment.
