The zebrafish model has attracted much attention due to its strong reproductive ability, short research cycle, and ease of maintenance. It has always been an important vertebrate model system, often used to carry out human disease research. Its motor behavior features have the advantages of being simpler, more intuitive, and quantifiable. In recent years, it has received widespread attention in the study of traditional Chinese medicine(TCM)for the treatment of sleep disorders, neurodegenerative diseases, fatigue, epilepsy, and other diseases. This paper reviews the characteristics of zebrafish motor behavior and its applications in the pharmacodynamic verification and mechanism research of TCM extracts, active ingredients, and TCM compounds, as well as in active ingredient screening and safety evaluation. The paper also analyzes its advantages and disadvantages, with the aim of improving the breadth and depth of zebrafish and its motor behavior applications in the field of TCM research.

In hepatocytes,the endoplasmic reticulum and mitochondria work together in a reciprocal manner to regulate the physiological functions of the cells.Nevertheless,its precise mechanism remains unknown.Endoplasmic reticulum-associated degradation (ERAD) is a key process for maintaining pro-tein quality in the endoplasmic reticulum.Recent studies have found that ERAD can regulate the adipo-cyte mitochondrial function through mitochondria associated membranes (MAMs).However,it is still unknown how exactly ERAD and mitochondria interact with one another in hepatocytes.In this study,chemical induction and gene deletion were used to induce ERAD deficiency in HepG2 cells.To investi-gate the effect of ERAD on mitochondrial function in hepatocytes,we employed fluorescent labelling,flow analysis,immunoblotting and other methods.The results demonstrated that ERAD dysfunction resulted in a reduction in the mitochondrial membrane potential and ATP levels in HepG2 cells (P<0.01) .Fur-thermore,ERAD dysfunction also disrupted the endoplasmic reticulum and mitochondrial Ca2+homeosta-sis in HepG2 cells,and improved mitochondrial energy metabolism function when endoplasmic reticulum Ca2+release was reduced (P<0.05) .These findings were further validated in ERAD dysfunctional pri-mary hepatocytes,which had been induced by pharmacological agents.The data above indicate that ERAD plays a key regulatory role in endoplasmic reticulum-mitochondrial interactions in hepatocytes.En-hanced ERAD function may boost mitochondrial activity in hepatocytes.This study offers fresh perspec-tives on disorders linked to mitochondrial malfunction.

Tumors are new organisms formed by uncontrollable cell proliferation of local tissues driven by various oncogenic factors. The cause of tumors is unknown with life-threating outcome. Tumors can be classified into benign tumors， borderline tumors， and malignant tumors according to their pathological properties. Among them， malignant tumor is commonly known as cancer， with no specific medicines or reliable cure means， so this is a hot spot and difficult point in current medical research. In ancient literatures， there are many records about the efficacy of Chinese herbal medicine in treating tumor， and modern pharmacological researches have shown that more and more active ingredients of traditional Chinese medicine（TCM） have gradually highlighted their inhibitory effect on various types of tumor. Caulis sinomenii has been used for treatment of rheumatic diseases in TCM for a long history. Sinomenine is a major bioactive alkaloid presented in C. sinomenii， which has demonstrated a wide range of pharmacological activities such as anti-inflammation， immunosuppression， analgesia and sedation， and due to its slightly soluble in water， it is commonly used in clinic in the form of hydrochloride， with its commercial name of Zhengqing Fengtongning. Recent studies show that sinomenine alone or combined with chemoradiotherapy can inhibit growth of several tumors significantly or in a synergistic way， so it is termed as an inhibitor of tumors. Anti-tumor effect of sinomenine involve inhibition of tumor cell proliferation， induction of tumor cell apoptosis， blockade of tumor cell cycle， suppression of tumor invasion and metastasis， induction of autophagy of tumor cells， and reversal of multidrug resistance of tumor cells. Upon combination with nanomaterials， it can enhance efficiency and reduce toxicity. Here we summarized and reviewed recent advances on basic anti-tumor research of sinomenine， and then made a classification and description according to its in vivo and in vitro pharmacological action and mechanism of action， so as to elucidate the great potential of sinomenine as a promising anti-tumor drug， and provide reference for further research on its anti-tumor mechanism.

Objective: To explore the diagnosis and clinical features of internal carotid artery aneurysm in the skull base. Methods: The data of 15 patients with internal carotid aneurysms in the skull base diagnosed and treated by digital subtraction angiography (DSA) or CT angiography (CTA) in the Provincial Hospital Affiliated to Shandong First Medical University from 1995 to 2017 were collected and analyzed. Among the 15 patients, 12 were males, and 3 were females, aging from 17 to 67 years old, with a median age of 44 years. Thirteen patients were diagnosed by DSA; the other two patients were diagnosed by CTA. Thirteen patients were diagnosed with pseudoaneurysm with the first symptom of epistaxis, in which eight patients underwent head trauma and 5 underwent radiotherapy of skull base tumor. The other two patients were diagnosed with true aneurysm presented headache and cranial nerve disorder. All patients were followed up for 2 to 12 years after treatment to see whether they were cured and survived. Results: Among the eight patients with a history of trauma, five patients were cured by embolization, two patients without embolization died of massive epistaxis, one patient died of progressive cerebral infarction after embolization. Among the five patients with radiotherapy of skull base tumor, one patient died of cerebral infarction after embolization, two patients died out of the hospital due to the recurrence of the primary tumor and intracranial invasion, one patient recovered well after embolization and surgical operation, one patient gave up treatment and died of massive hemorrhage out of hospital. In the other two patients with symptom of headache, one received embolization treatment outside the hospital after receiving mistake operation, and another one gave up treatment and died due to personal reasons. In total, four patients died in hospital, four died out of the hospital, and seven patients survived. Conclusions: Internal carotid artery aneurysm is a high-risk disease of anterior and middle skull base. For patients with epistaxis with a history of trauma and radiotherapy or patients with headaches and cranial nerve disorders, the possibility of the internal carotid artery aneurysm should be considered, in which DSA or CTA examination is essentially required for ensured diagnosis and disease evaluation.. The correct diagnosis and treatment by the otolaryngologist are crucial to the prognosis of the patient.

Objective: To analyze and summarize the diagnosis, treatment and prognosis of granulomatosis with polyangiitis (GPA) with nasal symptoms as the first clinical manifestation. Methods: The data of 18 patients of GPA with nasal mucosal symptoms as the first clinical manifestation from the Department of Otorhinolaryngology Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University between 2005 and 2019 was collected, including 8 males and 10 females, aged from 5 to 68 years. Nasal endoscopy, imaging examination, laboratory examination, immunological and histopathological examination of nasal mucosa were completed. All patients were treated with glucocorticoid combined with cyclophosphamide and were followed up for 2 to 15 years. Descriptive statistical method was used for analysis. Results: All the 18 patients had the nasal mucosal symptoms as the first clinical manifestation, including nasal obstruction, running nose and epistaxis. Nasal endoscopy showed swelling, erosion, scab and bleeding of nasal mucosa, and 6 cases had nasal septal perforation. Nasal sinus CT scan showed high density shadow of sinus, as well as hyperostosis and osteosclerosis. CT imaging features of pulmonary showed nodular lesion or patchy infiltration in 12 patients and cavitation was found in 6 cases. Laboratory results showed that 13 cases were positive for anti-neutrophil cytoplasmic antibodies (ANCA), and 5 cases were negative. During follow-up period, thirteen patients were symptomatic controlled and survived; two patients died of disease progression; one patient gave up treatment and died; two patients were lost to follow-up. Conclusions: Nasal symptoms are the first clinical manifestation of GPA. Early diagnosis and early treatment with glucocorticoid combined with cyclophosphamide can effectively improve the survival rate.

OBJECTIVE: To observe the therapeutic effect of acupuncture combined with cranial electrotherapy stimulation (CES) on generalized anxiety disorder (GAD). METHODS: A total of 200 patients with GAD were randomized into an acupuncture+CES group, an acupuncture group, a CES group and a medication group, 50 cases in each one. In the medication group, patients were treated with tandospirone citrate tablet orally, 10 mg after breakfast, lunch and dinner respectively. In the CES group, CES was adopted by SCS brain electromedical instrument, 60 min each time, once a day. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Sishencong (EX-HN 1), Yintang (GV 29), Shenting (GV 24), etc., 30 min each time, once a day. In the acupuncture+CES group, CES was adopted before acupuncture. Treatment of sixty days was required in the 4 groups. Before and after treatment, the scores of Hamilton anxiety scale (HAMA), World Health Organization's quality of life questionnaire-brief version (WHOQOL-BREF) and treatment emergent symptom scale (TESS) were observed, the clinical effect was evaluated, and the relapse of anxiety during follow-up of 1 year after treatment was recorded in the 4 groups. RESULTS: Compared before treatment, the scores of HAMA after treatment were decreased ( CONCLUSION Acupuncture combined with CES can effectively relieve the symptoms in patients with GAD, improve the quality of life, reduce the occurrence of adverse reactions and the relapse rate, and its clinical effect is obviously superior to the western medication, the simple application of acupuncture or CES.
