Objective The continuous and discrete Bayesian network models of serum uric acid and related metabolic indexes were established to explore the influencing factors of serum uric acid and compare the characteristics and advantages of the results of the two networks.Methods A total of 4646 patients with serum uric acid and metabolic diseases from chronic disease monitoring in Shanxi Province in 2015 were selected.IPCB algorithm was used to establish a continuous Bayesian network of serum uric acid.Meanwhile,the above indicators were discretized,and MMHC was used to establish a discrete Bayesian network of high uric acid.Results The discrete Bayesian network found 14 edges,in which triglyceride and diastolic blood pressure abnormalities were directly related to the occurrence of high uric acid,leading to the occurrence of high uric acid.Age was an indirect factor;Age,TG,LDL,HDL,SP and DP are directly related to uric acid level.With the increase of age,TG and LDL and the decrease of HDL,uric acid level increases,while the increase of uric acid level leads to the increase of SP and DP.TC is indirectly related to uric acid.Conclusion The two network models adapt to different data types,but the continuous Bayesian network has more direct correlation factors and better overall explanatory degree.

Objective:To explore the feasibility of soft copy image of chest digital radiography (DR SC) in pneumoconiosis diagnosis by observing the reading effect of DR SC and comparing it with high kV film-screen chest radiography (FSR HkV) . To provide a basis for the establishment of a regional information network platform for pneumoconiosis diagnosis. Methods:A total of 119 miners who were exposed to silica dust and engaged in copper or lead-zinc mining were collected by the Third People's Hospital of Yunnan from October 2017 to August 2019. The pulmonary X-ray findings of DRSC and FSR HkV in each case were independently judged and diagnosed by three experienced diagnostic physicians, and the final decision was made according to the consensus of most doctors. The consistency of the two imaging methods was analyzed by observing the main small opacity shape, the overall density, the range of distribution, the aggregation of the small opacity and the big opacity, and the diagnosis stage. Results:there were 118 males and 1 female with an average age of 46.21 years. Average exposure time 7.38 years. The pulmonary X-ray findings of 113 cases with two imaging methods were mainly the round small opacity of p,q and r,but the reticular irregular opacity were not prominent, Only one case of FSR HkV judgment p shape and DR SC judgment q shape were observed, The coincidence rate was 99.12% (112/113) . huger opacity were observed in the other 6 cases. The coincidence rate was 95.51% (4/89) between pneumoconiosis-free and stageⅠ, and there was no significant difference between stageⅡand stage Ⅲ (30/30, P>0.05) . Conclusion:The x-ray findings of Silicosis with small round shadow in lung can be used by DR SC in diagnosis and staging.

Objective: To summarize the clinical manifestations and treatment of retinal artery occlusion and cerebral infarction caused by facial injection of hyaluronic acid. Methods: Fifteen cases (15 eyes) with vision lose caused by facial cosmetic injection of hyaluronic acid visited Xi＇an No.4 Hospital from December 2010 to January 2017. The clinical data were collected such as general medical history and treatment methods, and follow-up for 1 year. Results: All patients were female, 22-41 years old, with average age of 33. All patients were injected with hyaluronic acid. For 8 patients the fillers were injected in the forehead, 3 patients were in the glabellar region, 3 patients were in the nasolabial fold, and 1 patient was in the temporal of left eye. All patients had vision lose after injection, the visiting time was 1 to 6 hours. 13 patients were central retinal artery occlusion (CRAO). 1 patient was retinal branch artery occlusion (BRAO), 1 patient was ischemic optic neuropathy (ION), 13 patients manifested as no light perception (NLP), 1 patient was 0.6, 1 patient was CF/30 cm, and 14 patients with cerebral infarction, manifested as headache, dizziness. All patients were given emergency treatment, and 9 patients had treated with interventional thrombolysis therapy. After treatment 11 patients, visual acuity had no significant improvement, but 4 patients improved. Headache, dizziness symptoms disappeared, but cerebral infarction lesions still existed on MRI. Conclusions Human face is a rich blood supply; vision loss and cerebral infarction could occur after injection of hyaluronic acid. After urgent treatment visual acuity is not improved obviously, eventually leading to irreversible visual impairment or even loss.
