This study aims to evaluate the bioactivity of five components of the traditional Chinese medicine complex prescription Jiangzhi granules against hepatocellular steatosis.

Objective To analyze the correlation between emphysema extent measured by high resolution computed tomography (HRCT) and pulmonary function tests, symptom score in patients with chronic obstructive pulmonary disease ( COPD ) , and to study the value of HRCT in the emphysema quantification in the clinical evaluation of COPD patients. Methods 78 patients with stable COPD were recruited to take the HRCT scan , and emphysema extent was qualified by measuring the proportion of low attenuation area in the whole lung (LAA%). Correlations between LAA% and indices of pulmonary function test, bronchial dilation test, mMRC scale, CAT score and six minutes walking distance (6MWD) were assessed. Results LAA% was negatively correlated with FEV1/FVC and DLCO%pred, and the correlation coefficients were -0.759 and -0.589 (P <0.01), respectively. LAA% was positively related to mMRC score (r = 0.342, P < 0.01), and negatively asso-ciated with 6MWD (r = -0.365,P< 0.01). There was no association between LAA% and indices of bronchodila-tion test (⊿FVC, ⊿FVC%, ⊿FEV1, ⊿FEV1%) (P > 0.05). Conclusions The severity of emphysema measured by HRCT is well correlated with the clinical symptoms , pulmonary function tests and exercise capacity in COPD patients. It can be used to diagnose emphysema early and to evaluate the severity of the disease com-prehensively. Thus, the risk factors of COPD can be controlled and the prognosis of the patients can be im-proved.

Autoimmune hepatitis (AIH) is an autoimmune-mediated chronic progressive liver inflammatory disease with unknown pathogenesis. The main purpose of AIH treatment at present is to relieve symptoms, improve liver function and pathological abnormalities, and slow down the progression to liver fibrosis. Easy recurrence and a large difference in prognosis bring difficulties to the treatment of this disease. In recent years, AIH treatment methods mainly include standard immunosuppressive therapy, substitutive therapy or second-line therapy for ineffective standard therapy, traditional Chinese medicine treatment with reduced side effects, and liver transplantation rescue therapy for end-stage AIH or severe fulminant AIH. This article reviews the above treatment methods for AIH, in order to provide a reference for clinical application.

Objective: To investigate the clinical features of childhood epilepsy with occipital paroxysms. Methods: The clinical data of 33 children admitted to our hospital from 2015 to 2019 were retrospectively analyzed. Results: The children were divided into three groups: idiopathic group (n=20), structural group (n=10) and genetic group (n=3). Among the structural etiology group, there were 1 case of megagyrus malformation, 1 case of focal cortical dysplasia type Ⅱ (FCDⅡ), 1 case of gestational age infant with enlarged ventricle, and 7 cases of perinatal ischemic-hypoxic encephalopathy (HIE). In the genetic group, there were 1 case of PCDH19 gene mutation, 1 case of cyclin-dependent kinase like 5 (CDKL5) deficiency disorder and 1 case of Wolf-Hirschhorn syndrome. All three groups had ocular motor symptoms and secondary motor symptoms. Compared with the structural group, patients of the idiopathic group had more autonomic symptoms, less visual symptoms, longer ictal duration, less episodes, less abnormal background rhythm, and more epileptic discharges in the frontal lobe or Rolandic area. The genetic group had frequent seizures and the CDKL5 deficiency disorder patient had slowed background and spasms. Compared with the other two groups, patients of the idiopathic group had fewer MRI abnormalities, better seizure control effect, and better prognosis. Conclusions There are many causes of childhood epilepsy with occipital paroxysms. The idiopathic group accounts for a large proportion. The visual symptoms and autonomic symptoms are different between groups. Background abnormalities are detected more often in the structural group and the genetic group, which is also helpful for differential diagnosis. The treatment options and prognosis of different groups vary greatly. The overall therapeutic effect and prognosis of the idiopathic group are better than those of the structural group and the genetic group.
