RESUMEN
Hyperspectral imaging (HSI) has been applied to assess the texture profile analysis (TPA) of processed meat. However, whether the texture profiles of live fish muscle could be assessed using HSI has not been determined. In this study, we evaluated the texture profile of four muscle regions of live common carp by scanning the corresponding skin regions using HSI. We collected skin hyperspectral information from four regions of 387 scaled and live common carp. Eight texture indicators of the muscle corresponding to each skin region were measured. With the skin HSI of live common carp, six machine learning (ML) models were used to predict the muscle texture indicators. Backpropagation artificial neural network (BP-ANN), partial least-square regression (PLSR), and least-square support vector machine (LS-SVM) were identified as the optimal models for predicting the texture parameters of the dorsal (coefficients of determination for prediction (rp) ranged from 0.9191 to 0.9847, and the root-mean-square error for prediction ranged from 0.1070 to 0.3165), pectoral (rp ranged from 0.9033 to 0.9574, and RMSEP ranged from 0.2285 to 0.3930), abdominal (rp ranged from 0.9070 to 0.9776, and RMSEP ranged from 0.1649 to 0.3601), and gluteal (rp ranged from 0.8726 to 0.9768, and RMSEP ranged from 0.1804 to 0.3938) regions. The optimal ML models and skin HSI data were employed to generate visual prediction maps of TPA values in common carp muscles. These results demonstrated that skin HSI and the optimal models can be used to rapidly and accurately determine the texture qualities of different muscle regions in common carp.
RESUMEN
OBJECTIVE: To find a better method for treatment of acute lumbar disc herniation. METHODS: One hundred cases were randomly divided into 2 groups. The observation group of 52 cases was treated with electroacupuncture at Yaoyangguan (GV 3), Dachangshu (BL 25), Guanyuanshu (BL 26), Xiaochangshu (BI. 27) as main points, and blood-letting puncture at stagnant collaterals nearby Weizhong (BL 40); the control group of 48 cases was treated with traction combined with electroacupuncture at main points Jiaji (EX-B 2), Shenshu (BL 23), Dachangshu (BL 25). Their therapeutic effects were observed and compared. RESULTS: The cured rate and the cured markedly effective rate were 55.8% and 82.7% in the observation group and 33.3% and 54.2% in the control group, respectively, with significant differences between the two groups (P < 0.05, P < 0.01). CONCLUSION: Electroacupuncture combined with blood letting puncture at stagnant collaterals nearby Weizhong (BL 40) has a signifi cant therapeutic effect on acute lumbar disc herniation.
