Objective To assay Icariine, Epimedin C, asperosaponin Ⅵ, psoralen and angelicin in Xianlinggubao capsules via multi-wavelength HPLC method.Methods Separation was carried out on Welch Ultimate○R XB-C18 column.The mobile phase was acetonitrile-water system and a linear gradient elution was used.The column temperature was 30 ℃.The detection wavelength for Icariine, Epimedin C,asperosaponin Ⅵ was set at 212 nm, psoralen and angelicin at 246 nm.Results Five components reached baseline separation, the linearity was good when sample size was in the range of 0.008 2-0.328 μg for Icariine(r=0.999 5), 0.055 6-2.224 μg for Epimedin C (r=0.999 6), 0.144 1-5.764 μg for asperosaponin Ⅵ(r=0.999 6), 0.005 4-0.215 2 μg for psoralen(r=0.998 0), 0.006 6-0.265 6 μg for angelicin(r=0.998 5).The average recoveries were 97.59％, 98.58％, 98.11％, 97.86％, 98.22％ respectively.The RSDs of recovery were all less than 2.0％.Conclusion This method is simple, accurate, with good separation, high sensitivity for the assay of multiple components in Xianlinggubao capsule.

Objective:To investigate the clinical characteristics of a patient with motor neuron disease,which caused sleep-disordered breathing (SDB) and alveolar hypoventilation syndrome,and to improve the diagnosis rate for this disease.Methods:Retrospectively analyze the diagnosis and treatment process for a 52 year-old male patient,who was accepted by the Second Xiangya Hospital,Central South University because of dyspnea,shortness of breath and malaise for 4 months,and eventually was diagnosed as motor neuron disease associated with obstructive sleep apnea hypopnea syndrome and alveolar hypoventilation syndrome.In addition,we searched CNKI,Wanfang and PubMed databases to review relevant literature with keywords (motor neuron disease or amyotrophic lateral sclerosis or progressive bulbar palsy or progressive muscular atrophy or primary lateral sclerosis) AND (sleep apnea or sleep disordered breathing) from January 1990 to May 2017.Results:The major clinical manifestation of motor neuron disease induded impaired upper and lower motor neuron displayed with proximal musde weakness,musde tremor,amyotrophy,bulbar symptoms and pyramidal sign.It was a chronic,progressive disease with worse prognosis,low survival and difficult in diagnosis.Electroneuromyography was a vital way for diagnosis.Furthermore,sleep disordered breathing was common in patients with motor neuron disease,which was featured as decreased rapid eye movement sleep,increased awaking time,apnea and hypopnea.The main mechanism for sleep disordered breathing in motor neuron disease might be due to the disturbed central nervous system and paralysis of diaphragm and respiratory muscle.Moreover,the patient suffered from restrictive ventilatory dysfunction,alveolar hypoventilation and subsequent partial pressure of carbon dioxide and hypoxernia.Therefore,respiratory failure was the most frequent cause of death for patients with motor neuron disease.Non-invasive positive pressure ventilation was suggested to apply to such patients,whose forced vital capability was less than 75 percent of predicted value.Conclusion:Sleep disordered breathing is common in patients with motor neuron disease.Hence,polysomnography is suggested as a routine examination to confirm the potential complications and give timely therapy.Treatment with non-invasive positive pressure ventilation is important for patients to improve life qualit,survival rate and prognosis.

A case of a young male patient,who came to the Second Xiangya Hospital,Central South University because of snoring for 10 years and nocturnal gatism for half month,was analyzed retrospectively.He was diagnosed as obstructive sleep apnea hypopnea syndrome (OSAHS) finally.The patient had been diagnosed and treated as stroke in the local hospital,while urinary and anal incontinence were not relieved.It was a dilemma for him to be properly diagnosed and treated.Polysomnography in our hospital revealed apnea hypopnea index (AHI) at 44.7 events/h,oxygen desaturation index (ODI) at 70.8 events/h and the longest apnea time at 185 seconds while the lowest blood oxygen saturation reduced to 31％.In addition,413 events of apnea accounted for 61.2％ of the sleep time and the minimal heart rate was 23 times/min.The patient was diagnosed as severe OSAHS with hypoxia metabolic brain disease,moderate pulmonary arterial hypertension,secondary polycythemia and obesity hypoventilation syndrome finally.He received the treatment of positive airway pressure non-invasive ventilator with an average pressure at 11.7 cmH2O with reduced AHI and increased blood oxygen saturation.The urinary and anal incontinence disappeared during the first night of treatment and it has been totally resolved so far.We considered that gatism was secondary to OSAHS with severe hypoxia resulted from attenuated regulation of primary defecation in the night.Physicians should pay attention to OSAHS when accepting obese patients with nocturnal incontinence,obvious daytime sleepiness and night snoring.Urinary and anal incontinence could be completely disappeared under therapy of positive airway pressure.

【Objective】 To investigate the efficacy of autologous ozoneized blood transfusion(AOBT) in improving consciousness and motor function in convalescent stroke patients. 【Methods】 A total of 44 patients who were diagnosed as convalescent cerebral apoplexy and received treatment in Rehabilitation Department of our hospital from August 2016 to September 2021 were randomly divided into the experimental group and control group by blind method. The experimental group (n=22) received general rehabilitation training (such as exercises, occupational therapy, acupuncture and transcranial magnetic stimulation) plus AOBT (200 mL venous phlebotomy at the median elbow), once every 2 to 3 days and 12 occasions as a course of treatment; the control group solely recieved general rehabilitation training. The consciousness (GCS score) and ability of daily living (Barthel index score) score of the two groups before and after treatment were statistically compared, and Ueda motor function grade, Brunnstrom stage and muscle tone grade were observed and evaluated. 【Results】 After the treatment, the experimental group and the control were compared as follows: 1) the GCS score and Barthel score was 14.82±0.39 vs 12.41±2.52, 61.14±12.24 vs 52.05±11.72(P<0.05); 2) The recovery rate of motor function was 95.45% (21/22) vs 63.64% (14/22) (P<0.05); 3) The total recovery rate of muscle tone was 90.91% (20/22) vs 63.64% (14/22) (P<0.05). 【Conclusion】 AOBT, with somewhat high safety and effectiveness, can improve the state of consciousness, motor function and muscle tone in convalescent patients with stroke.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

OBJECTIVES: Pulmonary alveolar proteinosis (PAP) is a rare disease with non-specific and various clinical manifestations, often leading to misdiagnosis. This study aims to raise the awareness of this disease via summarizing the clinical characteristics, diagnosis, and therapy of PAP. METHODS: We retrospectively analyzed clinical data of 25 hospitalized cases of PAP during 2008 and 2019 in the Department of Respiratory and Critical Care Medicine of the Second Xiangya Hospital of Central South University. RESULTS: Cough with unkown reason and dyspnea were common clinical manifastations of PAP. Five patients had a history of occupational inhalational exposure. Sixteen patients had typical image features including ground-glass opacification of alveolar spaces and thickening of the interlobular and intralobular septa, in typical shapes called crazy-paving and geographic pattern. Fourteen patients underwent pulmonary function tests, revealing a reduction in the diffusing capacity for carbon monoxide. The positive rate of transbronchial biopsy was 95%. Five patients received the whole lung lavage and the symptoms and imaging fcauters significantly relieved after five-years follow-up. CONCLUSIONS PAP is characterized by radiographic pattern and pathology. Transbronchial lung biopsy is effective to make diagnosis of PAP. The whole lung lavage remains a efficient therapy.
