A quantitative proton nuclear magnetic resonance(qHNMR) method was established to determine the glucose content in commercially available Massa Medicata Fermentata(MMF) products and explore the variations of glucose content in MMF products during processing. The qHNMR spectrum of MMF in deuterium oxide was obtained with 2,2,3,3-d_4-3-(trimethylsilyl) propionate sodium salt as the internal standard substance. With the doublet peaks of terminal hydrogen of glucose with chemical shift at δ 4.65 and δ 5.24 as quantitative peaks, the content of glucose in MMF samples was determined. The glucose content showed a good linear relationship within the range of 0.10-6.44 mg·mL~(-1). The relative standard deviations(RSDs) of precision, stability, repeatability, and recovery for determination were all less than 2.3%. The glucose content varied in different commercially available MMF samples, which were associated with the different fermentation days, wheat bran-to-flour ratios, and processing methods. The glucose content in MMF first increased and then decreased over the fermentation time. Compared with the MMF products fermented with wheat bran or flour alone, the products fermented with both wheat bran and flour had increased glucose. The glucose content of bran-fried MMF was slightly lower than that of raw MMF, while the glucose content in charred MMF was extremely low. In conclusion, the qHNMR method established in this study is simple, fast, and accurate, serving as a new method for determining the glucose content in MMF. Furthermore, this study clarifies the variations of glucose content in MMF during processing, which can not only indicate the processing degree but also provide a scientific basis for revealing the fermentation mechanism and improving the quality control of MMF.

Sophorae Flavescentis Radix,derived from the root of Sophora flavescens in the Leguminosae family,has been widely used in the medicine,agriculture,animal husbandry,and daily chemical industry. A pharmacophore model-based method for rapid discovery of tyrosinase inhibitors( TIs) from S. flavescens was established by molecular docking under Lipinski rules,and verified by enzyme assays. Briefly,the chemical constituent database of S. flavescens( CDSF) was established based on the previous papers. Theoptimal pharmacophore model( OPM) was constructed by DS 2019 on the basis of known active TIs. Eighty-three hits predominated by flavonoids having higher fitting scores with OPM than the positive control were screened out,and subjected to molecular docking based on the three-dimensional structure of tyrosinase crystal protein. The potential TIs such as kurarinone and nor-kurarinone were rapidly discovered from the compounds with higher docking scores than the positive control under the Lipinski rules. The results were verified by the in vitro enzyme assays. The inhibition activities of tyrosinase from non-medicinal parts of S. flavescens were also tested to explore the relationship between the inhibition activity and chemical compositions. This study is expected to provide data support for the comprehensive application and development of S. flavescens and also a new method for the rapid discovery of active substances or functional constituents in the complex systems.

Objective: To develop a set of data elements and standardized definitions of Coronary Artery Disease and Creative Antithrombotic Clinical Research Collaboration (CardiaCare), aiming to facilitate the exchange of disparate data sources, enhance the abilities to support multicenter researches, and subsequently ensure the databases use under standardized process and criteria. Methods: The Cardiacare writing committee members reviewed data elements and definitions from published guidelines, clinical trials, databases, and standardized documents, then determined the data elements and standardized definitions, which should be included in CardiaCare. The writing committee also considered the specific domestic clinical management strategies during the establishment of Cardiacare. The resulting documents provide a series of key data elements and standardized definitions used in the management of coronary artery disease patients. Key data elements from CardiaCare could be sorted by clinical management flowsheet and outcome from hospitalization to long-term follow-up. Results: The Cardiacare standardized set comprised 864 data elements from admission to post-hospital follow-up visit. There were 8 tables in the documents, including demographic and admission information (23 elements), medical history and risk factors (102 elements), clinical presentations and diagnosis (22 elements), diagnostic and laboratory tests (111 elements), interventional diagnosis and treatment (118 elements), pharmacological therapy (213 elements), clinical outcomes (161 elements), and special subpopulations (114 elements: 87 elements for transcatheter valve replacement and 27 elements with cardiac rehabilitation). Conclusions: The Cardiacare standardized data elements set could provide support for real-world clinical research in consecutive data collection and databases mining. A wider applicability in various settings of CardiaCare needs to be explored further.

This study aims to investigate the effect of Huaier aqueous extract on the growth and metastasis of human non-small cell lung cancer NCI-H1299 cells and its underlying mechanisms. MTT assay was used to detect the effect of Huaier aqueous extract on the proliferation of NCI-H1299 cells. Flow cytometry was used to examine the effect of Huaier aqueous extract on the apoptosis, cell cycle, and ROS level of NCI-H1299 cells. Wound healing assay was used to evaluate the effect of Huaier aqueous extract on the migration ability of NCI-H1299 cells. Western blot was used to detect the levels of proteins involving apoptosis, epithelial-mesenchymal transition(EMT), and MAPK signaling pathway in NCI-H1299 cells exposed to Huaier aqueous extract. The results showed that Huaier aqueous extract inhibited the proliferation of NCI-H1299 cells, and induced cell-cycle arrest at the phase S. Huaier aqueous extract promoted the apoptosis of NCI-H1299 cells by down-regulating the expression of anti-apoptotic protein Bcl-2. Moreover, Huaier aqueous extract increased ROS level and induced ferroptosis in NCI-H1299 cells. EMT played a critical role in cancer metastasis. Huaier aqueous extract reduced the migration ability of NCI-H1299 cells by inhibiting EMT of NCI-H1299 cells. In addition, this study revealed that Huaier aqueous extract inhibited MAPK signaling pathway in human non-small cell lung cancer NCI-H1299 cells, which may be one of Huaier's mechanisms in inhibiting growth and metastasis of NCI-H1299 cells. This study provides a new theoretical basis for the clinical treatment of lung cancer with Huaier, and important reference significance for further studies on the anti-tumor mechanisms of Huaier.

Objective: To understand the effect of sirolimus on the erythropoiesis of K562 cell line and bone marrow cells from pure red cell aplasia (PRCA) patients and normal controls. Methods: Different concentrations (10, 100, 1 000 nmol/L) of sirolimus were added to the K562 cell line or bone marrow cells from PRCA patients or normal controls and cultured 14 days for BFU-E formation. Meanwhile, sirolimus was also added to the serum treated PRCA bone marrow cells to cultivate for the same priod of time. Results: Neither K562 cells, bone marrow cells from PRCA patients or normal controls showed any difference when sirolimus was added to the culture system for BFU-E. However, BFU-E formation decreased after serum was added in PRCA patients (76.40±22.48 vs 136.33±12.58, t=-4.329, P=0.001) and this suppression of BFU-E was partly corrected by 1 000 nmol/L sirolimus treatment (97.14±15.83 vs 76.40±22.48, P=0.038). Conclusions: Sirolimus may modulate the suppression of erythropoiesis by serum instead of directly stimulate the growth of red blood cells in PRCA patients.

Lung cancer is the leading cause of cancer-related deaths worldwide. Acquired drug resistance and metastasis are the main causes of treatment failure in lung cancer. Tumor microenvironment is a complex network for the survival and progression of tumor cells, in which inflammatory factors play a critical role in drug resistance and metastasis. Interleukin (IL)-8 is one of critical pro-inflammatory cytokines responsible for cell proliferation, invasion and metastasis, drug resistance and early recurrence in lung cancer. A serum based approach is advantageous for providing a real-time detection and evaluation of disease status in patients. In this review, we summarize the recent advances of IL-8 in predicting prognosis and radiation-induced lung toxicity (RILT), as well as increasing resistance and stem-like characteristics of lung cancer.

Objective To understand the forming cause of the Oncomelania hupensis snail-existent non-endemic areas of schistosomiasis(SENEAS),and to verify the conclusion of previous studies,so as to provide the evidence for schistosomiasis monitoring in such areas in Nantong City,Jiangsu Province. Methods The controlled field tests were carried out to observe the O. hupensis snails artificially infected by schistosome miracidia in SENEAS. The influence of the soil from SENEAS and the en-demic areas on O. hupensis snails artificially infected by miracidia were observed. Results All the experimental snails could be infected by schistosome miracidia except the smooth-shell snails from Tangyuan Village in the controlled field test environment of SENEAS or the endemic areas. The infection rates of the smooth-shell snails were lower than those of the ribbed-shell snails , but there were no statistically significant differences. The mortality rates of the smooth-shell snails were higher than those of the ribbed-shell snails,which were statistically significant (χ2Xindian = 135.118,χ2Shuangdian = 122.836,χ2Baipu =154.436,χ2Dingyan =138.288,χ2Control=151.923,all P<0.01). There were no significant differences in the infection rates of snails between each test group of the soil from SENEAS and the endemic areas(χ2Rugao=0.071,χ2Rudong=0.216,both P>0.05). Also there was no signifi-cant difference between each test group and the control group without soil(χ2=7.148,P>0.05). Conclusion It is likely to form the spread of schistosomiasis in SENEAS in Nantong City with sufficient amount of infection source of schistosomiasis im-ported. It is still necessary to implement the surveillance of schistosomiasis and O. hupensis snails in Nantong City.

Objective: To investigate the clinical effect of modified Snodgrass surgical technique in the treatment of hypospadias. METHODS: We retrospectively analyzed the clinical data about 212 cases of hypospadias treated by urethroplasty from January 2008 to October 2016, 94 with the modified Snodgrass technique, namely with a silk line in addition to the urethral suture to make easier postoperative removal of the suture (group A), and the other 118 with the conventional Snodgrass technique (group B). The urethral suture was removed at 10 days after surgery for the patients in group A. We compared the success rate of surgery and incidence of postoperative complications between the two groups. RESULTS: Compared with group B, group A showed a significantly higher success rate of surgery (81.36% vs 91.49%, P <0.05) but lower incidence rates of postoperative incisional infection (12.71% vs 4.26%, P <0.05) and urinary fistula (16.10% vs 6.38%, P <0.05). No statistically significant difference was found in the incidence of urethral stenosis between the two groups (2.54% vs 2.13%, P >0.05). CONCLUSIONS The modified Snodgrass technique can improve the success rate of surgery and reduce the incidence rates of incisional infection and urinary fistula, which deserves wide clinical application.
