The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

Objective:To investigate the genetic risk factors and prognosis of 190 patients with myelodysplastic syndrome(MDS). Methods:The clinical data of 190 patients with MDS admitted to the Department of Hematology,The First Affiliated Hospital of Chongqing Medical University from January 2015 to October 2020 were analyzed retrospectively,and the genetic background and survival curve of the patients were also analyzed. Results:MDS patients with higher risk according to International Prognostic Score System(IPSS)stratification at the time of initial diagnosis had more frequent and complex types of gene mutation and chromosomal abnormalities,indicating poor prognosis.The choice of treatment is associated with the prognosis of MDS patients with intermediate risk(IPSS stratification),and the relative risk of the overall survival rate of patients treated with hypomethylating agents is higher than that of patients on concomitant medication. Conclusion:MDS patients with higher-risk(IPSS stratification)have more complex genetic risk factors and lower survival rate than those with lower-risk(IPSS stratification).MDS patients with multiple genetic risk factors have a poor prognosis,and the type of gene mutation is a predictor of prognosis.

The on-site treatment, pretreatment and routine cleaning of silicone oil attached ophthalmic surgical instruments were investigated by questionnaire from November 2019 to January 2020.Results:18.033% (11/61) hospitals had mixed silicone oil attached ophthalmic surgical instruments and other instruments intraoperatively, 11.475% (7/61) hospitals didn′t wipe silicone oil and other visible contaminants postoperatively. 18.033% (11/61) hospitals didn′t carry out pretreatment and 4.000% (2/50) hospitals used saline as pretreatment solution; 54.098% (33/61) hospitals were involved in ultrasonic cleaning. 32.787% (20/61) hospitals had water temperature 31-37 ℃ and 4.918% (3/61) hospitals had water temperature>37 ℃during the cleaning process; During pretreatment and routine cleaning, 38.000% (19/50) hospitals and 54.902% (28/51) hospitals selected enzymatic detergent respectively, the contact time between instruments and detergent in specialized hospital was more standardized than that in general hospital ( P<0.001); In flushing, rinsing and final rinsing, there were 29.412% (15/51) hospitals, 11.765% (6/51) hospitals and 3.922% (2/51) hospitals used water that didn′t meet the requirements. 17.647% (9/51) hospitals, 13.725% (7/51) hospitals and 13.725% (7/51) hospitals didn′t record the time of flushing, rinsing and final rinsing. Conclusions:There are still some problems in the cleaning of silicone oil attached ophthalmic surgical instruments in specialized and general hospitals, such as no on-site treatment and pretreatment, improper control of cleaning parameters, and difficulty in ensuring water quality and water time. It is necessary to formulate the cleaning process specification of silicone oil attached ophthalmic surgical instruments as soon as possible to ensure the cleaning quality and avoid the occurrence of postoperative eye complications.

Objective: To evaluate the aerosol concentration(PM2.5,PM10.0 and aerosol particle number) formation in non-contact "air-puff" tonometry and provide suggestions for medical workers to take appropriate daily protection during the prevalence of 2019-nCoV. Methods: A cross-sectional study was carried out in this study. Thirty healthy subjects were enrolled on February 22, 2020 at Eye Hospital of Wenzhou Medical University. The intraocular pressure (IOP) was measured by non-contact "air-puff" tonometer in the ophthalmic consulting room and the hall with or without masks. PM2.5, PM10.0 and aerosol particles were recorded by air quality detector. The cumulative effects of IOP measurement, PM2.5, PM10.0 and aerosol particle number were analyzed, and the aerosol density of subjects with and without masks was compared. Results: The PM2.5, PM10.0 and aerosol particles produced by the non-contact "air-puff" tonometry and increased with the increase of spray times. The IOP curves of 60 eyes of 30 subjects were measured respectively in two environments of medical consulting room and medical institution hall. It was found that PM2.5, pm10.0 and particle number fluctuated and increased with the increase of IOP measurement person times, showing cumulative effect, and the accumulation speed of aerosol density in hall was faster than that in consulting room. The density of PM2.5 and PM10.0 produced without gauze mask were (53.417±2.306) and (85.350± 3.488) μg/m³, which were higher than those of (50.567±0.862) and (80.617±1.463) μg/m³ with gauze mask. The differences were statistically significant (P=0.028, 0.019). Conclusions Aerosol can be produced by non-contact "air-puff" tonometer spraying, and it fluctuates with the increase of spraying times, showing a cumulative effect. The aerosol accumulation is higher in the hall with insufficient air circulation. And more aerosol can be produced without gauze mask.
