Mongolians have a long history of using prescriptions, which can be classified into four stages as follows: the germination and experience accumulation stage before the 13 th century, the theoretical formation stage from the 13 th to 16 th century, the rapid development stage from the 17 th to 20 th century, and the leaping development stage from the mid-20 th century to the present. The prescriptions from the ancient classical or representative medical books have always been used by Mongolian physicians for generations, and they are still in use due to the definite curative effects. In 2008, the Notice on Issuing the Supplementary Provisions to the Registration and Management of Traditional Chinese Medicine(TCM) described that China has attached more importance to the excavation and development of classical prescriptions. As stipulated in the Law of the People's Republic of China on Traditional Chinese Medicine, the classical prescriptions should be those available in ancient TCM classics and still in wide use, with exact curative effects, distinct features, and obvious advantages. This paper expounded the historical formation and development of classical prescriptions in Mongo-lian medicine, introduced the five most influential ancient medical books revealing the formation and development of these classic prescriptions, and traced the origin of such classical prescriptions as Wenguanmu Siwei Decoction, Shouzhangshen Bawei Decoction, Jianghuang Siwei Decoction and summarized the origin, development history and characteristics of classical prescriptions in Mongolian medicine, aiming to provide a reference for their further research and development.

OBJECTIVE Programmed death ligand-1 (PD-L1) and indoleamine 2, 3-dioxygenase 1 (IDO1) are immune checkpoints which can be induced by interferon-γ(IFN-γ) in the tumor microenvironment, leading to immune escape of tumors. Myricetin (MY) is a flavonoid distributed in many edible and medicinal plants. The aim of this study is to clarify the effect and the mechanism of MY on inhibiting IFN-γ-induced PD-L1 and IDO1 in lung cancer cells. METHODS Expressions of PD-L1 and major histocompatibility complex-I (MHC-I) were evaluated by flow cytometry and Western blotting, and the expression of IDO1 was measured by Western blotting. qRT-PCR was used to detect their mRNA levels. The function of T cells was evaluated using a co-culture system consist of lung cancer cells and the Jurkat-PD-1 T cell line that overexpressing PD-1. Molecular docking analysis, Western blotting and immunofluorescence were used for mechanism study. RESULTS MY potently inhibited IFN-γ-induced PD-L1 and IDO1 expression in human lung cancer cells, while didn't show obvious effect on the expression of MHC-I. In addition, MY restored the survival, proliferation, CD69 expression and interleukin-2 (IL-2) secretion of Jurkat-PD-1 T cells suppressed by IFN-γ-treated lung cancer cells in the co-culture system. Mechanistically, IFN-γ up-regulated PD-L1 and IDO1 at the transcriptional level through the JAK-STAT-IRF1 axis, which was targeted and inhibited by MY. CONCLUSION Our research revealed a new insight into the anti-tumor effects of MY which inhibited IFN-γ-induced PD-L1 and IDO1 expression, supporting the potential of MY in anti-tumor immunotherapy.

OBJECTIVE: To study the application value of whole exome sequencing (WES) in critically ill neonates with inherited diseases. METHODS: A total of 66 critically ill neonates with suspected inherited diseases or unclear clinical diagnosis who were admitted to the neonatal intensive care unit were enrolled as subjects. The clinical data of the neonates were collected, and venous blood samples were collected from the neonates and their parents for WES. The clinical manifestations of the neonates were observed to search for related pathogenic gene mutations. RESULTS: Among the 66 critically ill neonates with suspected inherited diseases or unclear clinical diagnosis (34 boys and 32 girls), 14 (21%) were found to have gene mutations by WES. One neonate had no gene mutation detected by WES but was highly suspected of pigment incontinence based on clinical manifestations, and multiplex ligation-dependent probe amplification detected a heterozygous deletion mutation in exons 4-10 of the IKBKG gene. Among the 15 neonates with gene mutations, 10 (67%) had pathogenic gene mutation, 1 (7%) was suspected of pathogenic gene mutation, and 4 (27%) had gene mutations with unknown significance. Among the 15 neonates, 13 underwent chromosome examination, and only 1 neonate was found to have chromosome abnormality. CONCLUSIONS Chromosome examination cannot be used as a diagnostic method for inherited diseases, and WES detection technology is an important tool to find inherited diseases in critically ill neonates with suspected inherited diseases or unclear clinical diagnosis; however WES technology has some limitation and it is thus necessary to combine with other sequencing methods to achieve an early diagnosis.

Nagilactone E (NLE), a natural product with anticancer activities, is isolated from Podocarpus nagi. In this study, we reported that NLE increased programmed death ligand 1 (PD-L1) expressions at both protein and mRNA levels in human lung cancer cells, and enhanced its localization on the cell membrane. Mechanistically, NLE increased the phosphorylation and expression of c-Jun, and promoted the localization of c-Jun in the nucleus, while silencing of c-Jun by small interfering RNA (siRNA) reduced NLE-induced PD-L1. Further study showed that NLE activated the c-Jun N-terminal kinases (JNK), the upstream of c-Jun, and its inhibitor SP600125 reversed the NLE-increased PD-L1. Moreover, NLE-induced PD-L1 increased the binding intensity of PD-1 on the cell surface. In summary, NLE upregulates the expression of PD-L1 in lung cancer cells through the activation of JNK-c-Jun axis, which has the potential to combine with the PD-1/PD-L1 antibody therapies in lung cancer.

Laser induced breakdown spectroscopy ( LIBS ) was proposed to rapidly discriminate microbe species. Ten species of microbes were prepared in lab. Filter papers were selected as substrate for enriching bacteria and enhancing the quality of LIBS. The images of plasma were collected by ICCD camera and LIBS spectra were obtained by spectrometers. The results displayed that the images and spectra were different from 10 bacteria. It was demonstrated that this method was feasible to discriminate bacteria species by analyzing image and/or spectroscopy. Furthermore, nine smooth and multiple scattering correction ( MSC) were utilized to preprocess the LIBS full-spectrum data in the wavelength range of 200-420 nm and 560-680 nm. And principal component analysis ( PCA) and PCA-RF ( Random forest) were compared to validate the accuracy of discrimination. The investigation showed that the PCA-RF model coupled with suitable methods in preprocessing data could identify bacteria. The accuracy was 99. 6% for ten species of microbes by evaluating LIBS spectra in training set, and 96. 7% in predicting set. This report indicated that it is feasible to differentiate bacteria species by analyzing LIBS spectra.

BACKGROUND:β-tricalcium phosphate (β-TCP) and monocalciumphosphate monohydrate (MCPM) are traditionally considered as reactants for dicalcium phosphate dehydrate (DCPD) bone cement,but little is reported on the hydroxyapatite (HA) as a reactant.OBJECTIVE:To verify whether HA and MCPM can be used to prepare DCPD bone cement and to explore the physicochemical properties.METHODS:The HA and β-TCP were prepared by wet chemical precipitation method,and mixed with appropriate proportion of MCPM.Then,the HA-DCPD and β-TCP-DCPD were obtained by adding a proper amount of curing water.The composition and structure of the two materials were analyzed by X-ray diffraction,the morphology was observed by scanning electron microscope,and the mechanical strength was tested by Instron5567 universal material test machine.These two kinds of materials were placed in simulated body fluid for detecting the weight loss ratio,soaked for 14 days and taken out for X-ray diffraction and scanning electron microscope detection.RESULTS AND CONCLUSION:X-ray diffraction findings indicated that these two kinds of materials both belonged to high-purity DCPD bone cement.Under the scanning electron microscope,β-TCP-DCPD bone cement had dense crystal structure,with less pore number;however,the HA-DCPD bone cement presented with finer grains,loose structure,and higher pore number.With the increase of curing time,the mechanical strength of two kinds of bone cements was correspondingly increased,but the compressive strength of β-TCP-DCPD bone cement was significantly higher than that of HA-DCPD bone cement (P ＜ 0.05).In the simulated body fluid,the weight loss ratio of β-TCP-DCPD bone cement was significantly lower than that of HA-DCPD bone cement (P ＜ 0.05).At 14 days after soaking in the simulated body fluid,a layer of spherical particles that was formed on the surface of both materials was identified as hydroxyapatite by scanning electron microscope observation and X-ray diffraction analysis.In summary,HA-DCPD bone cement has good biodegradability,excellent bioactivity and bone conductivity,but poor mechanical properties.

Food intake has a great influence on blood glucose in patients with diabetes.This study was to determine the glycemic index (GI) and glycemic load (GL) of a particular pomelo named Majia pomelo and its effects on postprandial glucose (PPG) in patients with type 2 diabetes (T2D).Twenty healthy subjects and 20 T2D patients (controlled on lifestyle measures and/or metformin) were tested on 2 separate days with 50 g of glucose and 50 g equivalent of carbohydrates from Majia pomelo for GI measurement.To test effects of Majia pomelo on PPG,19 hospitalized T2D patients (controlled on insulin therapy) were selected for a 9-day study.The dose of insulin for each patient was adjusted on the first 3 days.A total of 100 mg Majia pomelo was consumed per meal in the last 3 tested days.Blood glucose was measured to evaluate the glycemic excursions.The GIs for Majia pomelo in healthy individuals and T2D patients were 78.34± 1.88 and 72.15±1.95 respectively.The value of GL was as low as 4.23 in diabetic patients with serving size of 100 g pomelo,indicting Majia pomelo as a high GI but low GL fruit.Consumption of Majia pomelo in hospitalized T2D patients did not cause significant glucose fluctuation.It was concluded that high GI pomelo can serve as a low GL fruit if it is consumed with a limited daily amount and thus can be supplied to diabetic patients.These results may mean more varieties of food choices for T2D patients.
