In order to clarify the name,plant species and clinical use of the traditional Uyghur medicine"Heliyun",this article combed Uyghur medical classics such as Ehtiyarat bedey,Aksaray,Jimi elaj and Mehzenul edwiye,as well as modern literature.Herbal textual research was performed on its name,origin,properties,functional indications,etc.At the same time,on-site inspections were conducted to verify the clinical use of"Heliyun"in Xinjiang Uyghur Medical Hospital,medicinal samples were collected,and original plant identification was conducted.After herbal textual research,confirmation of clinical use of medicinal materials in Uyghur medicine,and botanical identification,the Uyghur medicinal material"Heliyun"is actually the dried fruit of Withania somnifera(L.)Dunal,and the Chinese name for this medicinal plant should be"Shuiqieguo",and the Uyghur name remains"Heliyun".This could provide a basis for standardizing the name,confirming the plant species,and promoting the clinical application of"Heliyun"in Uyghur medicine.

Real-time acquisition of pulmonary ventilation and perfusion information through thoracic electrical impedance tomography (EIT) holds significant clinical value. This study proposes a novel method based on the rime (RIME) algorithm-optimized variational mode decomposition (VMD) to separate lung ventilation and perfusion signals directly from raw voltage data prior to EIT image reconstruction, enabling independent imaging of both parameters. To validate this approach, EIT data were collected from 16 healthy volunteers under normal breathing and inspiratory breath-holding conditions. The RIME algorithm was employed to optimize VMD parameters by minimizing envelope entropy as the fitness function. The optimized VMD was then applied to separate raw data across all measurement channels in EIT, with spectral analysis identifying relevant components to reconstruct ventilation and perfusion signals. Results demonstrated that the structural similarity index (SSIM) between perfusion images derived from normal breathing and breath-holding states averaged approximately 84% across all 16 subjects, significantly outperforming traditional frequency-domain filtering methods in perfusion imaging accuracy. This method offers a promising technical advancement for real-time monitoring of pulmonary ventilation and perfusion, holding significant value for advancing the clinical application of EIT in the diagnosis and treatment of respiratory diseases.

Objective To understand the exposure level of disinfection by-products (DBPs) in drinking water in Xiangyang City and to evaluate the health risks of the population, so as to provide reference for the safety risk control of drinking water. Methods Sampling and laboratory testing were conducted according to national standard methods. The risk assessment model provided by USEPA was used to evaluate the health risks. Results Trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM) and tribromomethane (TBM) were detected in drinking water in Xiangyang City. The contents of halogenated hydrocarbon DBPs in water disinfected with liquid chlorine were higher than those with chlorine dioxide. The contents of three DBPs were higher in wet season than those in dry season except TBM. The content of TCM in pipe network terminal water and secondary water supply disinfected with chlorine dioxide was higher than that in factory water. The carcinogenic risk of DBPs in drinking water disinfected with liquid chlorine was 4.33×10^-5, and the non-carcinogenic risk was 0.114. The carcinogenic risk of DBPs in drinking water disinfected with chlorine dioxide was 1.24×10^-6, and the non-carcinogenic risk was 3.15×10^-3. Conclusion The health risk of DBPs in drinking water in Xiangyang City is acceptable, but TCM produced by liquid chlorine disinfection should be paid more attention. It is recommended that chlorine dioxide disinfection be used to reduce the health risks of halogenated hydrocarbon DBPs.

Objective:To provide references for the diagnosis and aeromedical evaluation by analyzing the data of the flying personnel with cerebral arterial stenosis.Methods:The clinic and aeromedical evaluation data of the flying personnel, who were diagnosed as cerebral arterial stenosis when they hospitalized in Air Force Medical Center from September of 2009 to September of 2019, were reviewed.Results:Eight male flying personnel, aged 32-53 years old, were diagnosed as cerebral arterial stenosis. Five out of 8 flying personnel had the history of hypertension or smoking, and 2 suffered from arteritis. Among 3 neurological impairment cases, 1 was left carotid artery stenosis and 2 was middle cerebral artery stenosis or occlusion. Those 3 flying personnel were disqualified by aeromedical evaluation. The other 5 flying personnel without neurological impairment included 1 case of left subclavian artery stenosis with left renal artery stenosis, 1 case of intracranial stenosis of the left internal carotid artery, 2 cases of middle cerebral artery stenosis or occlusion, and 1 case of left anterior cerebral artery stenosis. Among them, 4 cases were diagnosed as silent brain infarction. The cerebral perfusion evaluation of those 4 cases indicated normal perfusion of the diseased vessels blood supply. Aeromedical waiver was decided upon the diagnosis as well as the considerations on the aircraft type they flied and their flight duty.Conclusion:The cerebral artery stenosis is living in flying personnel and atherosclerosis would be the main cause. Such clinical features as ischemic stroke or no neurological impairment may occur. The waiver should be considered according to the situations of cerebral perfusion and neurological impairment.

Objective To compare the medical selection standards of flying cadets in the nervous and mental system between Air Force of PLA(PLAAF) and the US Air Force(USAF), and to offer suggestions on revising PLAAF medical standards for flying cadets .Methods All our candidates who had participated in the final medical selection of flying cadets were subjected to neurological examinations , and determined as qualified or not according to USAF Medical Standards Directory.Results 123 people were disqualified during the neurological examination , accounting for 1.1% of the total. According to USAF Medical Standards Directory , 13 of them were disqualified , 24 of them were qualified , and 86 of them needed a second examination .There was marked difference between disqualification rates of PLAAF and USAF .Conclusion There are some differences in medical selection standards for flying cadets in the nervous and mental system between PLAAF and USAF, and we could revise PLAAF standards using USAF standards for reference .

Serious accidents of hazardous chemicals can cause a variety of acute or chronic impairment in human health. The effects of hazardous chemicals on human health can be identified by carrying on population exposure assessment. Through analyzing the domestic and overseas population exposure assessment cases related to hazardous chemicals accidents, we summarized that the base and key of the population exposure assessment were to identify the characteristics of the chemicals , delimit the area and the population exposed to the chemicals, and collect the data of the monitored chemicals and the population health in the polluted area.

Portal venous tumor emboli is one of the important factors that affect the prognosis of patients with hepatocellular carcinoma (HCC). There are different characters of surgery, interventional therapy, radiation therapy, treatment of local damage, targeted therapy in the treatment of portal venous tumor emboli, but the effects are not ideal. Scholars at home and abroad are exploring a variety of treatment patterns in the treatment of portal venous tumor emboli, to achieve better effect.Predominantly surgical comprehensive treatment can excision of tumor and tumor emboli, improve liver function, improve the quality of survival, prolong survival time. But the operation risk is big. Mainly non-surgical treatment has advantages of little trauma, less risk, and better local control of tumor emboli. But the efficiency, effect, alleviate period is ineffective. Therefore, the best treatment mode should be explored according to the different tumor emboli parting.
