In our review, we elucidate the myriad applications of transformers in drug discovery, as well as chemistry and biology, spanning from protein design and protein engineering, to molecular dynamics (MD), drug target identification, transformer-enabled drug virtual screening (VS), drug lead optimization, drug addiction, small data set challenges, chemical and biological image analysis, chemical language understanding, and single cell data. Finally, we conclude the survey by deliberating on promising trends in transformer models within the context of drug discovery and other sciences.

Objective To investigate the changes in the expression of cold-inducible RNA-binding protein (CIRBP) in a radiation-induced lung injury model. Methods Thirty male C57BL/6 mice were randomly divided by body weight into control group (no intervention) and model group (single chest X-ray irradiation with a dose of 20 Gy to build a radiation-induced lung injury model). The mice were dissected five weeks after irradiation. Hematoxylin-eosin staining and Masson staining were used to observe the pathological changes of the lung tissue and the deposition of collagen fibers. Immunohistochemistry was used to measure the expression of the inflammatory factors interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the lung tissue. qRT-PCR was used to measure the expression of CIRBP mRNA in the lung tissue. The expression of CIRBP protein in the lung tissue was determined by the immunofluorescence assay and Western blot. Results Compared with the control group, the model group showed significant pulmonary vascular congestion, significant inflammatory cell infiltration, significant thickening of some alveolar septa, significantly increased IL-6 expression [(129.41 ± 5.58) vs (187.22 ± 34.77), t = 3.179, P < 0.05], significantly increased TNF-α expression [(137.52 ± 23.53) vs (187.02 ± 19.16), t = 5.069, P < 0.05], significantly increased CIRBP mRNA expression [(1 ± 0.08) vs (1.97 ± 0.39), t = 3.45, P < 0.05], and significantly increased CIRBP protein expression [(9.32 ± 1.26) vs (14.76 ± 1.61), t = 3.751, P < 0.05], by the immunofluorescence assay; [(1.13 ± 0.17) vs (1.49 ± 0.14), t = 2.819, P < 0.05], by Western blot). Conclusion The expression of CIRBP is significantly increased in the radiation-induced lung injury model, which may be an important pro-inflammatory factor in radiation-induced lung injury.

Objective:To summarize the midterm to long-term outcomes and experiences of endovascular treatment (ET) of spontaneous isolated superior mesenteric artery dissection (SISMAD).Methods:The clinical data of 31 SISMAD patients from Jan 2011 to Dec 2019 treated with ET was retrospectively analyzed.Results:Successful ET was achieved in 29 patients with a technical success rate of 93.5%. A total of 36 self-expandable bare stents were planted in 28 patients and plain old balloon angioplastry (POBA) was performed in 1 patient. Abdominal pain disappeared within 24 hours in 89.3% of the patients after stenting. The rate of perioperative complication was 3.2%. There was no SMA dissection rupture bleeding, nor perioperative death occurred. The mean follow-up time was 53.5 (range, 6 to 110) months. There was no dissecting aneurysm formation, no SMA rupture and bleeding, and no stent rupture during the follow-up. The post ET 1-year, 3-year, and 5-year free from reintervention rate were 100%, 100%, and 91.7%, respectively.Conclusions:ET for SISMAD is safe and effective with satisfactory perioperative and midterm to long-term outcomes.

Objective:To evaluate the imaging features of CT scan in patients with COVID-19.Methods:Clinical data of 56 patients with COVID-19 from January 17 to 19, 2020 admitted to Wenzhou Central Hospital and the Second Affiliated Hospital of Wenzhou Medical University were retrospectively reviewed. The clinical manifestations, lung imaging characteristics and treatment outcomes of patients with different severity were analyzed with SAS software.Results:Fever (92.8%, 52/56), dry cough (75.0%, 42/56) and asthenia (58.9%, 33/56) were the first symptoms in most of the patients; some patients also had shortness of breath (25.0%, 14/56) and pharyngeal pain (10.7%, 6/56). Chest high-resolution CT scan showed that in 42 moderate patients, ground glass-like high-density shadows in the lung were observed in 30 cases (71.4%) ; localized plaque consolidation shadows and bronchial inflation signs were observed in 10 cases (23.8%). In 12 severe patients, 11 had high-density patches involving multiple lung lobes (≥3). In 2 critically ill patients the patches and stripes involving the entire lung were observed; and cord-like high-density shadow, local consolidation and fibrosis were also shown.Conclusion:The multiple ground-glass changes outside the lungs are early imaging manifestations of COVID-19 patients. The increase in pulmonary lobe consolidation and fibrosis may indicate the disease progression, and the degree of lung consolidation and fibrosis is closely related to the disease severity.

Objective To evaluate the effects of the quality-improving program on reducing the bloodstream infection of preterm infants in NICU.The program included emphasizing hand hygiene,strictly controlling the use of antibiotics and following the extubation indications of peripherally inserted central catheter (PICC).Method From October 2016 to March 2017,preterm infants admitted to NICU after the implementation of quality improvement program were assigned into the intervention group,and the infants admitted from April 2016 to September 2016 without the program were in the control group.The x2 test and t test were used to analyse the effects of the program,the rate of bloodstream infection and related complications.Result A total of 432 cases were enrolled in this study.Among them,221 cases were in the intervention group and 211 cases the control group.The rate of hand hygiene in the intervention group was significantly higher and the duration of antibiotic use per 1 000 hospitalization days and the average days of retaining the PICC were significantly shorter than the control group (P ＜ 0.001).The incidence of bloodstream infection in the intervention group was lower than the control group (5.9％ vs.11.4％,P =0.047),and the duration of non-invasive ventilation,parenteral nutrition,average hospitalization days,and the incidence of stage 11 and above necrotizing enterocolitis were lower than the control group (P ＜ 0.05).Conclusion The evidence-based quality improvement program has positive effects on reducing the bloodstream infections and related complications of preterm infants in NICU.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR₂) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR₂ rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR₂. All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR₂ compared with non-KIT D816 group (23.1% vs 57.1%, χ²=7.559, P=0.006), and patients with longer CR₁ duration achieved significantly higher CR₂ than those with CR₁ duration less than 12 months (74.1% vs 31.9%, χ²=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR₁ duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.
