RESUMEN
Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.

The study is to investigate the effect of glaucocalyxin A (GLA) on mast cell-mediated anaphylaxis. The animal welfare and experimental process of this experiment followed the regulations of the Animal Ethics Committee of Yanbian University. BALB/c mice were used in the animal experiment and randomly divided into five groups, control group, model group, and GLA low, medium, and high dose groups (10, 20, and 40 mg·kg-1). Mice were sensitized by intradermal injection of anti-dinitrophenyl-immunoglobulin E (DNP-IgE) into the ears and challenged with a mixture of DNP-human serum albumin (HSA) and 4% evans blue into the tail veins to prepare an animal skin passive cutaneous anaphylaxis (PCA) model, which was collected from both ears for measurement of dye staining and histology. Rat peritoneal mast cells (RPMCs) were used in the cell experiment and divided into control, IgE + antigen (Ag), and IgE + Ag + GLA groups to determine histamine release as well as calcium influx levels. High-affinity IgE receptor (FcεRI)-mediated signaling pathway proteins and HMGB1/TLR4/NF-κB (high mobility group box 1/toll like receptor 4/nuclear transcription factor kappa B) signaling proteins were detected by Western blot. The results of animal experiments suggest that GLA inhibits PCA, reduces evans blue dye exudation, and reduces ear inflammation and ear thickness in mice. The results of cellular experiments suggested that GLA could reduce histamine release and calcium influx, and inhibit tumor necrosis factor-α (TNF-α), interleukin (IL)-4, IL-13, and IL-1β production; Western blot results showed that GLA inhibited FcεRI-mediated phosphorylation levels of spleen tyrosine kinase (Syk), Lck/Yes novel tyrosine kinase (Lyn), tyrosine kinase Fyn (Fyn), growth-factor receptor-bound protein 2 (Gab2), and phospholipase C (PLC) γ1, while GLA inhibited HMGB1/TLR4 signaling pathway to limit NF-κB p65 nuclear metastasis. The results indicate that GLA inhibits mast cell degranulation and attenuates allergic inflammation through the HMGB1/TLR4/NF-κB signaling pathway.

RESUMEN
Liuwei Dihuang Pills is a typical traditional Chinese medicine with "the same product made by many manufacturers". The quality and price of products made in various factories was different obviously. In this study, the quality differences of Liuwei Dihuang Pills were evaluated over multi-dimensions and throughout the whole production cycle involving raw materials, production process, quality control and post-marketing re-studies based on the "Chinese patent medicine evaluation standard with quality at the core" established earlier by our research group. The research results showed that the product quality of various manufacturers was significantly different, and the product quality was positively correlated with the market shares of enterprises, indicating that enterprises with more market shares paid more attention to product quality; and the sales determined the concern degree of enterprises on products, which was in line with general cognition. During the single-item evaluation of Liuwei Dihuang Pills, the score of raw material selection was relatively low, and the enterprises paid less attention to the initial raw materials. The whole production process was better, and the national compulsory implementation of "Production Quality Management Standard"(GMP) had a positive effect in improving product quality. Quality control could basically guarantee product quality. Intelligent manufacturing promoted by the government was beneficial to ensure product uniformity. The score rate of "quality evaluation" item was basically qualified, which indicated that the quality control level of Liuwei Dihuang Pills was acceptable as a whole, but there was still room for improvement. "Re-evaluation and Brand Construction" had the lowest scores, reflecting that enterprises did not pay enough attention to in-depth study and re-evaluation of "the same product made by many manufacturers". The evaluation results were in line with expectations, provided a reference example for the evaluation of high-quality Chinese patent medicine, a basis for the high-quality and good price of Chinese patent medicine, scientific data for improving medical insurance bidding, and thus facilitated promoting the healthy development of the traditional Chinese medicine industry.

RESUMEN
<p><b>BACKGROUND</b>Statins improve arterial stiffness in patients with coronary artery disease (CAD). Hypertension is a predominant contributor of arterial stiffening. However, the influence of hypertension on the effect of statins for improving arterial stiffness in CAD patients has seldom been investigated. Therefore, in this study, we investigated the relationships between statin use and arterial stiffness in normotensive and hypertensive CAD patients.</p><p><b>METHODS</b>Brachial-ankle pulse wave velocity (ba-PWV) was measured in 437 patients, including 220 hypertensive CAD patients (121 used statins, 99 did not) and 217 normotensive CAD patients (105 used statins, 112 did not). The normotensive and hypertensive CAD patients were matched according to age, sex, and body mass index (BMI).</p><p><b>RESULTS</b>In the normotensive and hypertensive CAD patients, lipid profiles were significantly improved in the statin group compared with the non-statin group. No significant differences in the administered statins (i.e., atorvastatin, simvastatin, rosuvastatin, and pravastatin) and statin therapy duration were found between normotensive and hypertensive CAD patients (all P > 0.05). No significant correlation of ba-PWV and statin therapy duration was found in all CAD patients, normotensive CAD patients, or hypertensive CAD patients (all P > 0.05). ba-PWV in the statin group was significantly lower than that in the non-statin group in normotensive CAD patients ((1331.68 ± 167.52) cm/s vs. (1468.61 ± 244.54) cm/s, P = 0.002) but not in hypertensive CAD patients (P > 0.05). In multiple linear regression analyses, statin therapy was significantly associated with ba-PWV after adjusting for confounding variables in normotensive CAD patients (P = 0.018) but not in hypertensive CAD patients (P > 0.05).</p><p><b>CONCLUSIONS</b>Statins may significantly improve arterial stiffness in CAD patients, and hypertension may probably influence the effectiveness of statin therapy in improving arterial stiffness in this population. Further studies are required to investigate the effect of statins on arterial stiffness in normotensive and hypertensive CAD patients.</p>

<p><b>OBJECTIVE</b>To assess the clinical efficacy of global traditional Chinese medicine (TCM) therapy in treating senile advanced non-small cell lung cancer (NSCLC), with the aim of seeking a standardized, rational and economical way to treat advanced NSCLC in old patients.</p><p><b>METHODS</b>A retrospective analysis and comparison was carried out in 86 patients with senile advanced NSCLC, 44 treated by global TCM (TCM group) and 42 by chemotherapy (control group) through dynamical observation on related indexes including tumor size, quality of life and the survival time, as well as on the fee for medical service at various time points in the course of the treatment.</p><p><b>RESULTS</b>The changes of tumor size, score of clinical main symptoms and behavior condition (by ZPS scoring), as well as survival rates in the two groups at corresponding time points, were not different significantly (P>0.05). The mean survival time in the TCM group was 13.20+/-1.52 months and that in the chemotherapy group was 13.45+/-1.94 months, showing insignificant difference between them. However, the median survival time in the TCM group (12 months) was actually longer than that in the chemotherapy group (9 months, P<0.05). The mean daily expense and the mean expense (RMB yuan) for each patient in the TCM group were significantly lower than that in the control group, which was 180.73+/-93.21 vs 825.84+/-329.63 for the mean daily expense and 34077.21+/-14638.04 vs 58516.59+/-45429.76 for the mean expense for each patient (both P<0.01).</p><p><b>CONCLUSION</b>Treatment of senile advanced NSCLC with TCM alone has its apparent superiority in stabilizing tumor focus, improving clinical symptoms, elevating quality of life and prolonging the survival time. TCM is also less expensive, making it a good alternative therapeutic approach for this specific group of people.</p>
