Abstract
This study investigated the effects of different drying methods on the drying characteristics, three-dimensional (3D) appearance, color, total polysaccharide content (TPC), antioxidant activity, and microstructure of Pleurotus eryngii slices. The drying methods included hot air drying (HAD), infrared drying (ID), and microwave drying (MD). The results showed that the drying method and conditions significantly influenced the drying time, with MD having a significant advantage in reducing the drying time. The 3D appearance of P. eryngii slices was evaluated based on shrinkage and roughness as quantitative indexes, and the best appearance was obtained by hot air drying at 55 and 65 °C. HAD and ID at lower drying temperatures obtained better color, TPC, and antioxidant activity, but MD significantly damaged the color and nutritional quality of P. eryngii. The microstructure of dried P. eryngii slices was observed using scanning electron microscopy, and the results showed that drying methods and conditions had an obvious effect on the microstructure of P. eryngii slices. Scattered mycelia were clearly observed in P. eryngii samples dried by HAD and ID at lower drying temperatures, while high drying temperatures led to the cross-linking and aggregation of mycelia. This study offers scientific and technical support for choosing appropriate drying methods to achieve a desirable appearance and quality of dried P. eryngii.

Abstract
Abstract
Introduction/Objective
Dengue virus (DENV) is an arthropod-borne virus which imposes a significant burden on the health system in most tropical and subtropical countries. In 2009, WHO classified Dengue into Dengue Without Warning Signs (DNWS), Dengue With Warning Signs (DWWS), and Severe Dengue (SD). This study aims to establish the prognostic value of predetermined hematological parameters and inflammatory biomarkers in assessing severity and progression of dengue infection among ages 5-14.
Methods/Case Report
A retrospective study was conducted to evaluate the Complete Blood Count, Inflammation biomarkers, and severity of dengue patients (5-14 of age). The diagnosis must be serologically confirmed by a positive NS1/IgM.
Results (if a Case Study enter NA)
A total of 36 patients participated in the study, having 18 from each groups of DWWS and SD. The mean age of Dengue cohort was 13.9 years with 59% (19/36) being male. Laboratory findings reveal SD to have lower platelet count (<100.00x109/L) during day 1-3 (p<0.001). Low WBC count (<4.00x109/L), Relative Eosinophil (<2.00%), and Absolute Lymphocyte count (<1.52x109/L) were evident on days 1-3 among DWWS and SD cases (p=0.023; p=0.045; p=0.033). Low relative neutrophil (<0.45%) was a constant finding in both clinical types throughout disease progression. SD group had significantly higher Neutrophil to Lymphocyte ratio (NLR) values among SD cases on days 4-6 (p<0.001). In contrast, Platelet to Lymphocyte ratio (PLR) was significantly lower among DWWS cases on days 4-6 (p=0.020). Monocyte to Lymphocyte (MLR) ratio had poor discriminative power (p=0.560).
Conclusion
The findings highlight decreased platelet, WBC, relative eosinophil, and absolute lymphocyte count to be common among Dengue patients. NLR and PLR were found to be good predictors of dengue severity during the initial phase of infection. Evaluating these values may aid clinicians in early diagnosis of severe dengue. However, larger samples are needed to further validate the predictive values of these parameters.

Abstract
BACKGROUND This study aims to investigate the value of oral contrast ultrasonography (OCUS) in the diagnosis of gastric cancer in elderly patients. METHODS OCUS data obtained from patients ≥ 60 years old were retrospectively analyzed and compared with gastroscopy results. RESULTS Among the 12,716 subjects examined by OCUS, 5021 subjects were ≥ 60 years old, which accounted for 39.48% (5021/12,716). Gastritis, gastric polyp, benign ulcer, and gastric cancer were detected by OCUS in 1099 patients. Among them, 196 patients underwent gastroscopy. Furthermore, ulcerative lesions were detected in 32 patients by OCUS and in 51 patients by gastroscopy, and the coincidence rate was 62.74%. Among these patients, gastric cancer was diagnosed in 18 patients by OCUS with a detection rate of 1.64% (18/1099) and detected in 19 patients by gastroscopy with a diagnostic coincidence rate of 94.73% (18/19). Furthermore, benign ulcer was detected in 14 patients by OCUS and in 32 patients by gastroscopy, and the diagnostic coincidence rate was 43.75% (14/32). CONCLUSION OCUS helps to timely detect senile gastric cancer and can be used as a suitable technique for the detection of gastric diseases.

Abstract
OBJECTIVE To investigate the clinical value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of prostate cancer in patients with different concentrations of prostate-specific antigen (PSA). METHODS Based on the PSA concentration, 186 patients were divided into three groups (PSA 4-10 μg/L, 11-20 μg/L, and >20 μg/L) and underwent transrectal CEUS and biopsy. We compared the pathological results with the CEUS features in different groups of patients and performed a statistical analysis on the characteristics of the CEUS manifestations of prostate cancer and benign prostatic lesions. RESULTS Of the 186 patients, 118 (63.4%) were diagnosed by biopsy with prostate cancer and the other 68 (36.6%) with benign prostatic lesions. The positive rate of CEUS in the diagnosis of prostate cancer was above 95% in all the three groups, significantly higher than that of conventional ultrasound in the PSA 4-10 and >10-20 μg/L groups (P <0.01). CONCLUSIONS Contrast-enhanced ultrasonography can achieve a high detection rate in the diagnosis of prostate cancer, especially for the patients with a low PSA concentration, and therefore can be used as one of the most valuable diagnostic techniques for this purpose.

Abstract
A sensitive biosensor based on acetylcholinesterase (AChE) and carbon nanosphere (CNS) immobilized on a glassy carbon electrode was developed for the detection of pesticides by the inhibition of AChE activity. The inhibition effect of the pesticides resulted in a decrease of current response of the acetylthiocholine chloride that was used as a substrate to obtain an electrochemical signal. When applied to the pesticides carbofuran and fenitrothion, the designed biosensor exhibited high sensitivity and low detection limits. The inhibition ratio of carbofuran and fenitrothion were linearly proportional to their concentrations ranging from 0.40 to 4.79 and 6.26 to 125.31 μg/L, respectively. The theoretical detection limits were found to be 0.082 μg/L for carbofuran and 2.61 μg/L for fenitrothion. Furthermore, as the biosensor offers good reproducibility and stability, it could be used for trace detection of pesticides in real samples. Compared with other AChE biosensors, the proposed biosensor was convenient and it exhibited extreme sensitivity to pesticides.

Abstract
Near infrared (NIR) spectroscopy combined with pattern recognition was attempted to discriminate the freshness of eggs. The algorithm of one-class support vector machine (OC-SVM) was employed to solve the classification problem due to imbalanced number of training samples. In this work, 86 samples of eggs (71 samples of fresh eggs and 15 samples of unfresh eggs) were surveyed by Fourier transform NIR spectroscopy. Firstly, original spectra of eggs in the wave-number range of 10 000-4 000 cm(-1) were acquired. And then, principal component analysis (PCA) was employed to extract useful information from original spectral data, and the number of PCs was optimized. Finally, OC-SVM was performed to calibrate discrimination model, and the optimal PCs were used as the input eigenvectors of model. In order to obtain a good performance, the regularization parameter v and parameter sigma of the kernel function in OC-SVM model were optimized in building model. The optimal OC-SVM model was obtained with nu = 0.5 and sigma2 = 20.3. Experimental result shows that OC-SVM got better performance than conventional two-class SVM model under the same condition. The OC-SVM model was achieved with identification rates of 80 for both fresh eggs and unfresh eggs in the independent prediction set. The identification rates of fresh eggs were 100% in two-class SVM model. However, when the two-class SVM model was used to discriminate the unfresh eggs of, the identification rates were 0% in the independent prediction set. Compared with conventional two-class SVM model, the OC-SVM model showed its superior performance in discrimination of minority unfresh eggs samples. This work shows that it is feasible to identify egg freshness using NIR spectroscopy, and OC-SVM is an excellent choice in solving the problem of imbalanced number of samples in training set.

Abstract
To simplify the prediction model of kiwifruit firmness, SNV was used to preprocess the near infrared (NIR) spectra (1 000-2 500 nm)of kiwifruit. PLS model simplification by optimizing spectral intervals and decreasing the number of factors through net analyte preprocessing (NAP)was carried out. Results showed that the performance of NAP/PLS model is the best. It was achieved with 5 factors in five wavenumber ranges(5 189-5 370, 4 549-4 620, 6 049-6 230, 6 999-7 730, and 6 249-6 614 cm(-1)). The optimal model was achieved with R2 = 0.819 41 and RMSECV = 0.701 77 in the calibration set and R2 = 0.780 67 and RMSEP = 0.882 71 in the prediction set. This indicates that the model not only may efficiently simplify PLS model, but also may improve precision and predictive ability.

Abstract
DNA studies of the translocation t(15;17) in acute promyelocytic leukemia (APL) have shown that the retinoic acid receptor alpha (RARA) gene on chromosome 17 is juxtaposed to the promyelocytic leukemia (PML) gene on chromosome 15. The PML breakpoints have been mapped to 3 clusters: bcr1, bcr2, and bcr3. We have examined the PML breakpoint distribution in a series of 33 Chinese patients with APL. Twenty-two patients fell within bcr1, 2 within bcr2, and 9 within bcr3. The primary structure of the reciprocal chromosome translocation joints of one patient and that of their normal counterparts have been determined and compared to those of 2 previously reported cases. These studies revealed possible topoisomerase II cleavage sites close to the breakpoints and suggested implications of DNA attachment sites to nuclear matrix. We propose that these features are relevant to the process of illegitimate recombination generating the translocation.

Abstract
In 100 cases with autoimmune hemolytic anemia, Coombs test was directly positive in 77 cases (77%). 82 patients had warm autoantibodies. IgM was increased in 12 patients. 3 patients were diagnosed as lymphoma with titers more than 1:1024. One patient had paroxysmal cold hemoglobinuria. The dramatic clinical response to corticosteroid therapy was observed in patients with warm autoantibodies. However, immunosuppressor should be given to patients with cold autoantibodies. It was suggested that combined therapy with two drugs may be more effective than the use of corticosteroid alone. Of 6 patients in whom splenectomy was performed, 4 showed excellent results. Out of 100 cases, there were 23 with Evans syndrome.
