Objective To construct a distance self-attention(DSA)and long short-term memory(LSTM)model and observe its value for predicting X-ray tube arcing in CT equipment.Methods CT equipment status data of internet of medical things were collected and preprocessed,then DSA-LSTM model based on model attention(MA)module and nonlinear attenuation distance factor was constructed,and its value for predicting X-ray tube arcing in CT equipment was analyzed compared with other models.Results Compared with other models,DSA-LSTM model had better comprehensive efficiency for predicting X-ray tube arcing in CT equipment.MA module and nonlinear attenuation distance factor could improve the predictive efficiency of DSA-LSTM model,and all included features contributed to the performance of DSA-LSTM model in a certain extent.Conclusion DSA-LSTM model could effectively predict X-ray tube arcing in CT equipment.

RESULTS AND CONCLUSION:(1) Motor function: The motor function scores were better in the acupuncture + rehabilitation group than in the model, acupuncture, and rehabilitation groups (P< 0.05). (2) Growth associated protein-43 and synaptophysin expression: immunohistochemical staining revealed that compared with the model group, growth associated protein-43 expression at 2-4 weeks and synaptophysin expression at 4 and 5 weeks were higher in the acupuncture and acupuncture + rehabilitation groups(P<0.05); the increase in above expression was most significant in the acupuncture + rehabilitation group (P<0.05). (3) Results confirmed that acupuncture combined with rehabilitation promoted growth associated protein-43 and synaptophysin expression in rats with cerebral palsy and exerted neuroprotective effect.

Objective: To observe the protective effect of BushenHuoxueFang on renal interstitial fibrosis in rats and try to explore the mechanism. Methods: The renal obstruction model of rats was established by unilateralureteral obstruction ,and then they were divided into four groups randomly, including sham-opration group,model group,Lotensin group, BushenHuoxueFang high-dose and low dose group.The morphological changes of kidney tissue were observed,the level of PDGF-BB was detected by Western-blot on the third,seventh,fourteenth and twenty first,twenty eighth day Results: Compared with the sham-operation group, there were different degrees of kidney lesions in UUO group and the treatment groups. The level of PDGF-BB in UUO group was significantly higher than that in sham-operation group from the third day(P
