OBJECTIVE: To investigate the information acquired through the four diagnostic methods of traditional Chinese medicine in patients with bronchial asthma, and to classify the syndrome types. METHODS: Four hundred and thirty patients with bronchial asthma were randomly investigated. The information acquired through the four diagnostic methods was recorded and the database was established by Amos software, and then the data were analyzed by confirmatory factor analysis (CFA). RESULTS: After analyzing the data with 4 factors, 5 factors and 6 factors, we found that the results of CFA with 6 factors were in accordance with clinical practical experience. CONCLUSION: According to the results of CFA with 6 factors and with the standard regression coefficient 0.4 as primary and secondary critical points, the syndromes in patients with bronchial asthma can be classified into 5 types, which are syndromes of cold fluid retained in lung, phlegm-heat obstructing lung, wind-phlegm blocking lung, qi deficiency of lung and kidney and qi deficiency of spleen.

Butanol is not only an important chemical feedstock but also expected to become a new generation biofuel. Thus, biological butanol production using renewable feedstocks has attracted renewed attention due to the worries of global oil supply and its impact on social and economic development. However, compared with petrochemical-derived butanol, biological butanol production is still not economically competition, because of its major drawbacks: high cost of the feedstocks, low butanol concentration in the fermentation broth and the co-production of low-value byproducts acetone and ethanol. Recently, Shanghai cooperative bio-butanol group (SCBG) developed a simple-to-complex technical route to improve bio-butanol production with a focus on: increasing butanol ratio in the solvent through metabolic engineering of Clostridia spp.; introducing and optimizing the butanol synthetic pathway in the species with high butanol tolerance; overcoming the glucose repression effect to utilize low-cost non-grain based feedstocks. SCBG believes that, through extensive domestic and international industry-university-research cooperation, a sustainable and economically viable process for biological butanol production can be established in the near future.

Objective:To evaluate the safety of ensartinib in the treatment of anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) in the real-world clinical setting.Methods:Clinical data of 2 221 patients with ALK-positive locally advanced or metastatic NSCLC who received ensartinib treatment (225 mg/d) from December 16, 2020 to December 16, 2021 were collected and analyzed to assess drug adverse reactions in all population including elderly patients (≥ 65 years old) .Results:Among the total 2 221 patients, 511 patients (23.01%) experienced adverse events, including 8 patients (0.36%) who experienced serious adverse events. Adverse events led to dose modification in 67 patients (3.02%) and discontinuation in 18 patients (0.81%). The common adverse events were rash (407/2 221, 18.33%), pruritus (41/2 221, 1.85%), constipation (41/2 221, 1.85%), and facial edema (31/2 221, 1.40%). Thirty-six patients (1.62%) experienced ≥grade 3 adverse events. After symptomatic treatment of 511 patients with adverse reactions, 50 patients (9.78%) were healed, 271 patients (53.03%) were improved, 120 patients (23.48%) were persisted, and 70 patients (13.71%) were unknown due to loss of follow-up or other reasons. Forty-three patients (1.94%) reported 57 unintended adverse reactions. Among the 599 elderly patients, 116 patients (19.37%) experienced adverse events, including 1 patient (0.17%) who experienced serious adverse events. Adverse events led to dose modification in 25 patients (4.17%) and discontinuation in 5 patients (0.83%). The common adverse events of elderly patients were rash (88/599, 14.69%), constipation (14/599, 2.34%), facial edema (12/599, 2.00%), and pruritus (10/599, 1.67%). Twelve patients (2.00%) experienced ≥grade 3 adverse events. Among the 116 elderly patients with adverse reactions following the symptomatic treatment, 11 patients (9.48%) were healed, 58 patients (50.00%) were improved, 28 patients (24.13%) were persisted, and 19 patients (16.39%) were unknown due to loss of follow-up or other reasons. During the treatment, 1 patient (0.05%) experienced grade 2 interstitial lung disease, and no patient died due to adverse events.Conclusion:Ensartinib has a favorable safety profile in the real-world populations, with the most frequent adverse events being rash, mostly mild, and low incidence of ≥grade 3 adverse events. Overall, adverse reactions were tolerable and manageable.
