Objective:To establish a prediction method of diopter based on sequence of ocular biological parameters.Methods:A stratified random cluster sampling method was used to extract the dataset. The dataset consisted of data collected from January 2022 to January 2023 by the Eye & ENT Hospital, Fudan University, from children aged 5 to 13 years in 2 key schools and 2 general schools of Yangpu District, Shanghai. Children’s ocular biological parameters, including sex, age, diopter, axial length, corneal curvature, and anterior chamber depth were collected. The slope of the optimally fitted straight line was calculated using the least squares method. The least square-back propagation (BP) neural network model was established by combining baseline data and the pre-processed rate of the change of ocular biological parameters. The dataset was divided into the training set and the validation set according to the ratio of 8:2 for five-fold cross-validation. The model performance was evaluated by using the mean absolute error (MAE), mean squared error (MSE), root mean square error (RMSE), correlation coefficient R, and coefficient of determination R2. Results:The optimal performances of R2, R, RMSE, MAE, and MSE of the least square-BP neural network model were 0.96, 0.981 9, 0.214 2, 0.139 9 D, 0.045 9, respectively. The regression equation between the predicted value and the true value of the diopter was y=0.97 x+ 0.014 8, R2=0.97, with good correlation. In the internal verification, MAE values of the diopter at three, six, nine, and twelve months of follow-up were 0.110 1, 0.136 0, 0.153 7, and 0.184 8 D, respectively, which achieved clinically acceptable performance (less than 0.25 D). In the external validation, the errors were less than 0.25 D at all ages. Conclusions:A prediction method of diopter based on sequence of ocular biological parameters was successfully developed.

ObjectiveTo explore the possible mechanism of Bushen Huoxue Formula （补肾活血方， BHF） in the treatment of Parkinson's disease （PD） from the the perspective of intestinal flora. MethodsSeventy-two male C57/BL6J mice were randomly divided into blank group， model group， Madopar group and low-， medium- and high-dose BHF groups， with 12 mice in each group. The mice in the blank group were intraperitoneally injected with 10 ml/kg of normal saline， and those in the other groups were intraperitoneally injected with 30 mg/kg of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine （MPTP） at a concentration of 3 mg/ml to induce PD mice model， both once a day for 7 consecutive days. After successful modeling， the low-， medium-， and high-dose BHF groups were given 7.5， 15， and 30 g/（kg·d） of BHF by gavage， respectively， while the Madopar group was given 112.5 mg/（kg ·d） of Domedopar tablets by gavage， and the blank group and the model group were given 15 ml/（kg·d） of distilled water， all once a day for 14 consecutive days. The rod climbing test， rotating rod test， grip strength test and weight-bearing swimming test were used to evaluate the behavioral indicators of mice. Western blotting was used to measure the protein expression levels of Toll-like receptor （TLR）/nuclear factor kappa B （NF-κB） pathway inflammatory factors in the mouse ileum， including Toll-like receptor 2 （TLR2）， Toll-like receptor 4 （TLR4）， NF-κB， tumor necrosis factor α （TNF-α）， interleukin 6 （IL-6）， and interleukin 17 （IL- 17）. 16S rRNA high-throughput sequencing was used to analyze changes in mouse intestinal flora. ResultsCompared to those in the blank group， the mice in the model group had longer bottoming time when climbing the pole， reduced grip strength， shortened rotary pole duration and swimming duration， and increased protein expression levels of TLR2， TLR4， NF-κB， TNF-α， and IL-6 in the ileal tissue （P＜0.01）. Compared to the model group， the Madopar group and the low-， medium- and high-dose BHF groups had shortened bottoming time of the climbing pole and increased grip strength； the Madopar group and the high-dose BHF group had prolonged rotary pole duration， and reduced protein expressions of TLR2， TLR4， NF-κB， TNF-α， IL-6， and IL-17 levels； and only the high-dose BHF group had prolonged swimming duration （P＜0.05 or P＜0.01）. Compared to those in the low-dose BHF group， the bottoming time of the climbing pole were shorter in the moderate- and high-dose groups （P＜0.05 or P＜0.01）， and the grip strength increased while the protein expression levels of TLR2， TLR4 and IL-17 decreased in the high-dose group （P＜0.05 or P＜0.01）. The intestinal flora results showed significant differences between the blank group and the model group in the Dominance index， Pielou_e index， Shannon index， and Simpson index （P＜0.05 or P＜0.01）. Compared to those of the model group， the Shannon index， Chao1 index， and Observed_otus index of the Madopar group， as well as the Chao1 index， Observed_otus index， Dominance index， Pielou_e index， Shannon index， and Simpson index of the high-dose BHF group all showed significantly statistical differences （P＜0.05 or P＜0.01）. At the phylum level， the relative abundance categories of bacterial phyla with statistically significant differences in each group included Proteobacteria， Bacteroidetes， and Firmicutes （P＜0.05 or P＜0.01）. At the genus level， the relative abundance categories of bacterial genera with statistically significant diffe-rences among each group included Muribaculaceae， Akkermansia， and Helicobacter pylori （P＜0.05 or P＜0.01）. ConclusionThe possible mechanism of BHF in treating PD may be to reconstruct the disordered intestinal flora structure and improve the inflammatory response.

Objective To explore the effect of aerobic exercise on renal function abnormalities and mitochondrial oxidative stress of obese rats.Methods Ninety 5-week male Sprague-Dawley rats were randomly divided into a normal diet group(CON,n=10)and a high-fat diet group(n=80).The latter group was on high-fat diet for 8 weeks to induce obesity with renal function abnormality.After success-ful modelling,40 rats were chosen and randomly divided into a high-fat diet control group(HFD)and three groups of high-fat diet+aerobic exercise with different intensities(40%VO2max,60%VO2max,and 80%VO2max),each of 10.All exercise groups underwent daily 60-min aerobic exercise on treadmill,5 days per week for 4 weeks.After the intervention,their body weight,body length,perirenal and epi-didymal fat weights were measured,and morphometric indices including fat-body ratio and Lee's in-dex were calculated.Moreover,such biochemical indicators of renal function as serum creatinine(SCr),serum cystatin C and urinary microalbumin(mALB)were tested.Meanwhile,the pathological changes of the kidney were observed using hematoxylin eosin(HE)staining and Periodic acid-Schiff(PAS)staining,while the ultrastructural changes of the kidney and mitochondria were observed using the transmission electron microscopy.Moreover,the levels of superoxide dismutase(SOD),malondialde-hyde(MDA),and mitochondrial membrane potential in mitochondria were evaluated using ELISA kits.Results After 4 weeks of intervention,the average SCr,serum cystatin C,and mALB levels in the HFD group increased significantly compared with the CON group(P<0.05).Moreover,the average SCr levels of all exercise groups were significantly lower than the HFD group(P<0.05),with the average serum cystatin C and mALB levels of the 60%VO2max and 80%VO2max groups significantly lower than the HFD group(P<0.05).Meanwhile,the renal tubular epithelial cells in the HFD group showed mod-erate degeneration and increased glomerulosclerosis index(GSI)(P<0.05)and the degree of glomerular hypertrophy in each exercise group was significantly lower than the HFD group,with the renal tubules of the 60%VO2max group showing a clearer contour and decreased GSI(P<0.05).What's more,com-pared with the CON group,the number of swollen mitochondria in the HFD group increased,but the mitochondria damage of the 60%VO2max group relieved significantly compared with the HFD group.The renal mitochondrial MDA levels in the CON group increased significantly compared with the HFD group(P<0.05),and those of the exercise groups were significantly lower than the HFD group(P<0.05),with the most significant decrease in the 40%VO2max group(P<0.05).Moreover,the average renal mito-chondrial SOD and membrane potential levels in the HFD group decreased significantly compared with the CON group(P<0.05),while those in the 40%and the 60%VO2max groups were significantly higher than the HFD group(P<0.05).Conclusion Moderate to low intensity aerobic exercise can relieve renal dysfunction of obese rats by lowering the level of oxidative stress in renal mitochondria,mainly down-regulating such renal function biochemical indicators as SCr,serum cystatin C,and mALB,as well as alleviating the degree of renal tissue damage.
