ObjectiveTo investigate the effect of Sanet Vision Integrator (SVI)-based visuomotor integration training on the severity of neglect symptoms, upper limb motor function and activities of daily living (ADL) in patients with post-stroke unilateral spatial neglect (USN). MethodsFrom July, 2023 to September, 2025, 41 patients with post-stroke USN in Beijing Bo'ai Hospital were enrolled and randomly assigned to control group (n = 20) and experimental group (n = 21). Both groups received conventional rehabilitation and visual scanning training, while the experimental group received supplementary SVI-based visuomotor integration training, including saccadic, rotation and hand-eye coordination training, for eight weeks. They were assessed with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, all the scores significantly improved in both groups (|t| > 4.004, P < 0.001), and the total scores of CBIT-HK and the core visual search sub-items (star cancellation, line crossing and letter cancellation), FMA-UE and MBI were better in the experimental group than in the control group (t > 2.096, P < 0.05). ConclusionSVI-based visuomotor training can effectively alleviate the USN symptoms, broaden the span of visual attention, facilitate the functional recovery of the affected upper extremity, and improve ADL in patients after stroke.

The purpose of this study is to investigate the effect of TPCK trypsin on the proliferation pattern of porcine epidemic diarrhea virus in Vero cells.The TPCK trypsin and conventional tryp-sin were added for virus proliferation,and RT-qPCR technology was used to analyze the changes in virus adsorption and invasion in Vero cells.The replication ability of porcine epidemic diarrhea vi-rus in Vero cells was explored through growth curve drawing,IFA identification,and cell activity detection.The results showed that the optimal concentrations of TPCK trypsin and conventional trypsin were 1 mg/L and 6 mg/L,respectively.The virus showed a decreasing trend with the pro-longation of TPCK trypsin and conventional trypsin pretreatment time.Adding different pancreatic enzymes during the virus proliferation process did not promote the virus invasion in Vero cells.Af-ter 4 h of invasion,the virus particles of each group gradually increased.By plotting the growth curve,it was found that the virus content of the TPCK trypsin group reached its highest level at 24 h(lgTCID50=(6.30±0.14)/0.1 mL),followed by a decreasing trend at 36 h,and the fluorescence intensity produced at 24 h was higher than that of conventional trypsin.In summary,TPCK trypsin has a better promoting effect on the proliferation of porcine epidemic diarrhea virus in Vero cells.It provided theoretical basis for further research on the mechanism of TPCK trypsin affecting porcine epidemic diarrhea virus proliferation,and also provided data support for the isola-tion and purification of porcine epidemic diarrhea virus epidemic strains.

This study was aimed to explore factors related to microalbuminuria of early stage of diabetic nephropathy (DN). Through epidemiologic survey, syndrome data of patients with early stage of DN were collected. The analysis was made on relationship between MAU (strain) of early stage of DN patients and the influencing factors (variable) with logistic regression analysis. The influencing factors were investigated in the early stage of DN patients in MAU. The epidemiological study showed a close relationship between factors such as active living style, easy irritability, drinking, old age, long disease course, phlegm and dampness body constitution, qi-stagnation body constitution, purple or dark tongue, thin and rapid pulse, yin deficiency and heat pattern, qi-yin deficiency pattern, cold and dampness pattern with the incidence of early stage of DN. It was concluded that there were 114 cases of early stage of DN with MAU of 20-52 μg·mL-1. The risk factors contained easy irritability, qi-stagnation body constitution, purple or dark tongue, yin deficiency and heat pattern, qi-yin deficiency pattern, as well as cold and dampness pattern. The protective factor contained active living style. There were 95 cases of early stage of DN with MAU of 53-199 μg·mL-1. The risk factors contained drinking, old age, long disease course, phlegm and dampness body constitution, as well as thin and rapid pulse.

Objective:To examine the association between food shortage and malnutrition in earlier life and diabetes mellitus in adulthood,to provide evidence for formulation of the strategy for preventing diabetes mellitus.Methods:The data of medical examination center(MEC)of a certain hospital in Chongqing was gathered.People born during the period of 1959 to 1964 were enrolled in the research.The study group was born from 1959 to 1960.The control group was born from 1962 to 1964.The attack rate and distribution of diabetes mellitus between two groups were compared by retrospective study.Results:The mean level of blood glucose was significantly higher in the 1960 group than that in non-famine group(P
