1.Nrf2: a new target for nonalcoholic fatty liver disease
Acta Pharmaceutica Sinica 2022;57(11):3268-3275
The liver is an important organ of the body, which has many functions, such as metabolism and detoxification. Due to the rapid change of lifestyle and the improvement of public health, the incidence rate of non-communicable diseases has increased significantly, which fundamentally changed the disease characteristics in most parts of the world. At present, the global prevalence of non-alcoholic fatty liver disease (NAFLD) is about 25%. Moreover, about 59.10% of NAFLD patients progress to non-alcoholic steatohepatitis (NASH) within 5 years, and about 41% of NASH patients progress to fibrosis. NAFLD has become one of the most important liver diseases in the world and may become the main cause of end-stage liver disease in the next few decades. In addition, NAFLD and related cirrhosis will bring huge economic burden to patients, health care system and society. Since there are currently no medications available that have been approved by Food and Drug Administration (FDA), NAFLD is still treated mainly through lifestyle changes such as exercise and diet. Oxidative stress and inflammation are the most important pathological processes in the occurrence and development of liver diseases. Nuclear factor erythroid-2-related factor 2 (Nrf2) is a key regulator of the body's antioxidant stress system, with anti-inflammatory, antioxidant and other functions. Many studies have shown that Nrf2 pathway significantly affects the progression of liver diseases. In this review, we aimed to summarize the regulatory role of the Kelch-like ECH-associating protein 1 (Keap1)-Nrf2-antioxidant response element (ARE) signaling pathway in the pathogenesis of NAFLD, and to reveal the potential of Nrf2 as a therapeutic target for NAFLD.

BACKGROUND:Muscle transposition is a conventional method to treat muscle tissue defects,but it results in damage to another piece of muscle.For this reason,we designed this study to search for a method to in situ repair muscle tissue defects.OBJECTIVE:To investigate the conditions for in vitro induced differentiation of rat bone marrow mesenchymal stem calls(BMSCs)into skeletal muscle cells.METHODS:Following isolation and culture,passage 3 BMSCs were induced to differentiate in vitro by a combination of5-azacytidine,myogenic differentiation factor,transforming growth factor β1,and insulin like growth factor.At 9 days after induction,cells were harvested and identified by immunohistochemistry.RESULTS AND CONCLUSION:Primary cultured BMSCs exhibited an adherent,colony-like growth.After 5-7 days,multi-synaptic calls,thin and fiat polygonal cells,polygonal cells,and triangle-shaped cells were observed.After 12 days,calls confluenced and covered the whole bottom of culture flask,with slightly altered morphology of BMSCs.After 5-azacytidine induction,some calls died and grew slowly.After 7 days,cells markedly grew and soma was gradually enlarged,presenting with an oval,spindle-shaped,or irregular appearance.After 14 days,spindle-shaped calls become more.After 18-22 days,myotubes were increased in number and enlarged in volume,and myotube nucleuses were also increased.The newly formed myotubes and spindle-shaped fibroblasts were distributed in parallel interval.The immunohistochemistry of BMSCs revealed that cells were positive for CD44,with dark brown granules in the cytoplasm,especially around the nucleus,but they were negative for CD34.The immunohistochemistry of induced BMSCs demonstrated that calls were positive for desmin and skeletal muscle myosins.These findings indicate that myogenic differentiation factors and 5-azacytidine could induce the oriented differentiation of BMSCs into skeletal cells,with the presence of positive expression of desmin and skeletal muscle myosins.

Objective To explore the management of deep vein thrombosis (DVT) of lower limbs in patients with severe craniocerebral injury.Methods The clinical data of 9 patients of severe craniocerebral injury with DVT were analyzed respectively.Results All 9 patients were given medicine therapy including thrombolytic, anti coagulating, anti platelet aggregation and antibiotics. 3 cases were cured, 1 case was improved, 4 cases died and 1 case discharged by himself. Conclusion There are risk factors for DVT in patients with severe craniocerebral injury. Early prophylaxis is important. Early diagnosis and treatment are benefited.

Minichromosome maintenance protein 7 (MCM7) is an important regulator of DNA replication,and plays an important role in replication initiation and elongation steps.Recent studies show that MCM7 is closely related with the formation and growth of digestive tumors.The detection of MCM7 protein can provide new ideas for the early diagnosis,treatment and prognosis of the digestive tumors.

This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.
