ABSTRACT
OBJECTIVE@#To observe the effect of Shugan Tiaoshen acupuncture (acupuncture for soothing the liver and regulating the mentality) combined with western medication on depression and sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, and investigate the potential mechanism from the perspective of cortical excitability.@*METHODS@#Sixty patients with depression-insomnia comorbidity due to COVID-19 quarantine were randomly divided into an acupuncture group and a sham-acupuncture group, 30 cases in each one. The patients of both groups were treated with oral administration of sertraline hydrochloride tablets. In the acupuncture group, Shugan Tiaoshen acupuncture was supplemented. Body acupuncture was applied to Yintang (GV 24+), Baihui (GV 20), Hegu (LI 4), Zhaohai (KI 6), Qihai (CV 6), etc. The intradermal needling was used at Xin (CO15), Gan (CO12) and Shen (CO10). In the sham-acupuncture group, the sham-acupuncture was given at the same points as the acupuncture group. The compensatory treatment was provided at the end of follow-up for the patients in the sham-acupuncture group. In both groups, the treatment was given once every two days, 3 times a week, for consecutive 8 weeks. The self-rating depression scale (SDS) and insomnia severity index (ISI) scores were compared between the two groups before and after treatment and 1 month after the end of treatment (follow-up) separately. The cortical excitability indexes (resting motor threshold [rMT], motor evoked potential amplitude [MEP-A], cortical resting period [CSP]) and the level of serum 5-hydroxytryptamine (5-HT) were measured before and after treatment in the two groups.@*RESULTS@#After treatment and in follow-up, SDS and ISI scores were decreased in both groups compared with those before treatment (P<0.05), and the scores in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05), and the decrease range in the acupuncture group after treatment was larger than that in the sham-acupuncture group (P<0.05). After treatment, rMT was reduced (P<0.05), while MEP-A and CSP were increased (P<0.05) in the acupuncture group compared with that before treatment. The levels of serum 5-HT in both groups were increased compared with those before treatment (P<0.05). The rMT in the acupuncture group was lower than that in the sham-acupuncture group, while MEP-A and CSP, as well as the level of serum 5-HT were higher in the acupuncture group in comparison with the sham-acupuncture group (P<0.05).@*CONCLUSION@#Shugan Tiaoshen acupuncture combined with western medication can relieve depression and improve sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, which is probably related to rectifying the imbalanced excitatory and inhibitory neuronal functions.

Objective@#To explore the clinical and radiological features of myelin oligodendrocyte glycoprotein (MOG) antibody associated disease.@*Methods@#The clinical data of 22 MOG antibody associated disease cases treated in the Department of Neurology, Qilu Hospital of Shandong University from January 2017 to June 2019 were retrospectively analyzed. The clinical data of MOG antibody associated disease were summarized, including clinical and imaging features.@*Results@#Of the 22 included patients with MOG antibody associated disease, the average age was 38.5 years, 13 were male and nine were female. Among them, 11 cases manifested as aquaporin-4 (AQP4)-negative neuromyelitis optica spectrum disorder (NMOSD), four cases optic neuritis, two cases transverse myelitis, one case acute disseminated encephalomyelitis (ADEM), two cases cortical encephalitis and two cases vestibular neuronitis. Magnetic resonance imaging (MRI) results showed that multiple anatomical areas were involved. Among the nine patients with optic nerve involvement, five patients had longitudinally extensive optic nerve lesions, which were longitudinally enhanced. In eight patients, MRI lesions in the spinal cord showed mostly long or short segments involvement, involving 2-5 spinal cord segments. Five cases involved the cervical spinal cord, six cases involved the thoracic spinal cord, and one case involved the lumbar spinal cord. Brain MRI abnormalities were found in 13 cases and the lesions were mostly patchy and point-shaped. MRI lesions demonstrated T2 hyperintensity and some of them could be strengthened, which may involve the basal ganglia, thalamus, radiographic crown, frontal temporal lobe, brain stem and other parts. Among them, 16 patients were sensitive to high-dose intravenous/oral methylprednisolone in the acute phase. Seven patients had recurrence after two months to two years of follow-up.@*Conclusions@#MOG antibody associated disease include multiple manifestations. Among them, AQP4-negative NMOSD is the most common form. The clinical manifestations of patients showed diversity. Imaging is characterized by multiple parts involvement such as optic nerve, spinal cord, and brain. Most patients are sensitive to high-dose intravenous/oral methylprednisolone, and have a good prognosis in the acute phase, but some patients may relapse.
ABSTRACT
Objective:To explore the etiology, clinical features and treatment of superficial siderosis of central nervous system (SSCNS) in China.Methods:The clinical data of four patients with SSCNS diagnosed by magnetic resonance imaging (MRI) and susceptibility weighted imaging (SWI) from Qilu Hospital of Shandong University during 2015—2019 were retrospectively reviewed. The etiology and clinical features of the four cases were summarized and analyzed.Results:All the four patients were male, with an average age of 60.5 years. Clinical symptoms included headache, hearing loss, and cerebellar ataxia. Brain MRI and SWI showed that hemosiderin mainly deposited (short linear T 2 signal, low SWI signal) on the surface of cerebellum, brainstem, temporal lobe, frontal lobe, and spinal cord. Potential bleeding sites were found in all four patients, including brain traumatic history, spinal intradural extramedullary cavernous hemangioma, brain metastasis and intracranial aneurysm. Patients were followed up for six months to four years. Headache symptoms improved in only one patient who received surgical treatment, while symptoms of the other three patients progressed. Conclusions:SSCNS is mainly characterized by hearing loss, progressive cerebellar ataxia and myelopathy. The diagnosis of this disease mainly depends on imaging examination. The linear low signal on the surface of T 2WI is the main basis for the diagnosis of SSCNS. Surgical treatment of bleeding sites and iron chelator are the main treatments of the disease.

ABSTRACT
OBJECTIVE: To establish an LC/MSn method for identification of the related substances in etimicn sulfate detected under the chromatographic condition described in Chinese Pharmacopoeia 2010. METHODS: The HPLC separation was carried out on a Welch Ultimate LP-C18 column (4.6 mm × 300 mm, 5 μm) with mobile phase consisting of 0.2 mol · L-1 trifluoroacetic acid (containing 0.1% propionic acid ) -methanol (84: 16) at a flow rate of 1.0 mL · min-1. Thirty percent of the eluent was detected by ion trap mass spectrometry, and the parent ions and the corresponding product spectra of all the related substances in etimicin sulfate were determined and elucidated. RESULTS: Addition of 0.1% propionic acid into the mobile phase significantly enhanced the sensitivity of MS detector without altering the chromatographic behavior such as retention time and elution order of the related substances. Twenty-eight related substances were separated and detected by the LC/MSn method in a typical sample. Nine of them were identified with the help of corresponding impurity reference substances and 14 of them were elucidated by MS fragment information, while the other five were not identified due to limitated information. CONCLUSION: The established method can be applied to the identification of the related substances in etimicn sulfate detected under the chromatographic condition described in Chinese Pharmacopoeia 2010, which is helpful to the quality improvement and process optimization of etmicin sulfate.
