ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone (TD) regimen in the treatment of newly diagnosed multiple myeloma (NDMM) with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st, 2015 to July 31th, 2019 were retrospectively analyzed, and they were divided into a control group (bortezomib/dexamethasone-containing regimen, 27 cases) and an observation group (cinobufagin tablets combined with TD regimen, 23 cases). The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate, one-year and two-year overall survival rate, and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow, hemoglobin, β2-microglobulin, lactate dehydrogenase, serum creatinine, blood urea nitrogen, bone pain score, and KPS functional status score (KPS score) before and after treatment. ResultsIn terms of clinical efficacy, there was no statistically significant difference (P>0.05) in the overall response rate [the observation group 69.57%(16/23) vs the control group 70.37% (19/27)] and deep remission rate [the observation group 56.52% (13/23) vs the control group 55.56% (15/27)] between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%, and the two-year overall survival rates were 81.8% and 80.9% respectively, with no statistically significant differences between groups (P>0.05). During the treatment, no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%, which was lower than 48.15% in the control group (P<0.01). After the treatment, the proportion of myeloma plasma cells, β2-microglobulin, serum creatinine level, and bone pain score decreased, while the hemoglobin level and KPS score increased in both groups (P<0.05 or P<0.01). Compared between groups after treatment, the bone pain score of the observation group was lower than that of the control group, while the KPS score was higher than that of the control group (P<0.05). ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen, but the former is more helpful in relieving the pain and improving the quality of life, and has better safety.

From the perspectives of traditional Chinese medicine (TCM) information knowledge base and assisted decision-making knowledge base, the construction status, quality evaluation status and existing problems of current TCM knowledge bases have been sorted out. And based on the quality evaluation strategies and dimensions of know-ledge bases in other disciplines, the evaluation indexes for TCM knowledge base is discussed, and the evaluation framework is initially formed, providing ideas for the improvement of the TCM knowledge base evaluation system. In terms of the evaluation indexes, there are basic evaluation dimensions which include data sources, data collection, and data application. The specific evaluation dimension of the information-based knowledge base is data quality, while that of the assisted decision-making knowledge base is data matching. Except for the data application dimension which counts the valid data items in the database for calculation, other indexes are scored based on the qualitative evaluation of "yes", "no" or "unknown". The basic evaluation score and the specific evaluation score are added to obtain the total score. The knowledge base is graded according to the score, and the results are presented in the form of grade plus number.

Consumptive thirst is widely discussed in Huangdi Neijing and it is classified as a"strange disease"in Suwen·Strange Diseases Treatise,which reflects the intractable nature of consumptive thirst.This paper explores and analyzes consumptive thirst based on the core concept in Huangdi Neijing.First,this paper approaches the subject through the use of image thinking method from Huangdi Neijing,recognizing that consumptive thirst can lead to changes in the internal climate of the human body.Then,guided by the theories of essence and qi,yin and yang,and the five elements in Huangdi Neijing,it deconstructs and analyzes the causes of these changes and the laws of qi transformation.It points out that the changing climate of consumptive thirst is characterized by"heat symptoms".The main cause of"heat symptoms"is spleen deficiency and excessive dampness,and its qi transformation law is the heat transformation of Shaoyin.The intractable nature of consumptive thirst is mainly reflected in the uncontrolled"heat symptoms"caused by the imbalance of the five elements.Based on the understanding of the heat symptoms of consumptive thirst,this paper proposes a treatment strategy for preventing the disease by resolving dampness and regulating the spleen,harmonizing kidney qi to prevent progression,and balancing yin and yang to treat chronic and recalcitrant conditions.The aim is to provide a reference for optimizing the treatment of consumptive thirst.

BACKGROUND:
Sarcopenia is an age-related progressive skeletal muscle disorder involving the loss of muscle mass or strength and physiological function. Efficient and precise AI algorithms may play a significant role in the diagnosis of sarcopenia. In this study, we aimed to develop a machine learning model for sarcopenia diagnosis using clinical characteristics and laboratory indicators of aging cohorts.
METHODS:
We developed models of sarcopenia using the baseline data from the West China Health and Aging Trend (WCHAT) study. For external validation, we used the Xiamen Aging Trend (XMAT) cohort. We compared the support vector machine (SVM), random forest (RF), eXtreme Gradient Boosting (XGB), and Wide and Deep (W&D) models. The area under the receiver operating curve (AUC) and accuracy (ACC) were used to evaluate the diagnostic efficiency of the models.
RESULTS:
The WCHAT cohort, which included a total of 4057 participants for the training and testing datasets, and the XMAT cohort, which consisted of 553 participants for the external validation dataset, were enrolled in this study. Among the four models, W&D had the best performance (AUC = 0.916 ± 0.006, ACC = 0.882 ± 0.006), followed by SVM (AUC =0.907 ± 0.004, ACC = 0.877 ± 0.006), XGB (AUC = 0.877 ± 0.005, ACC = 0.868 ± 0.005), and RF (AUC = 0.843 ± 0.031, ACC = 0.836 ± 0.024) in the training dataset. Meanwhile, in the testing dataset, the diagnostic efficiency of the models from large to small was W&D (AUC = 0.881, ACC = 0.862), XGB (AUC = 0.858, ACC = 0.861), RF (AUC = 0.843, ACC = 0.836), and SVM (AUC = 0.829, ACC = 0.857). In the external validation dataset, the performance of W&D (AUC = 0.970, ACC = 0.911) was the best among the four models, followed by RF (AUC = 0.830, ACC = 0.769), SVM (AUC = 0.766, ACC = 0.738), and XGB (AUC = 0.722, ACC = 0.749).
CONCLUSIONS:
The W&D model not only had excellent diagnostic performance for sarcopenia but also showed good economic efficiency and timeliness. It could be widely used in primary health care institutions or developing areas with an aging population.

Objective To identify the relationship between nephritis activity, autophagy and inflammation in patients with SLE. Methods Western blot analysis was used to detect the expression of microtubule-associated protein 1 light chain 3 (LC3) and P62 in peripheral blood mononuclear cells (PBMCs) of SLE patients with lupus nephritis and non-lupus nephritis patients. Tumor necrosis factor α (TNF-α) and interferon γ (IFN-γ) in the serum of SLE patients were determined by ELISA. The correlation between LC3II/LC3I ratio and SLE disease activity score (SLEDAI), urinary protein, TNF-α and IFN-γ levels was analyzed by Pearson method. Results The expression of LC3 was increased and P62 was decreased in SLE patients. TNF-α and IFN-γ were increased in the serum of SLE patients. LC3II/LC3I ratio was positively correlated with SLEDAI (r=0.4560), 24 hour urine protein (r=0.3753), IFN-γ (r=0.5685), but had no correlation with TNF-α (r=0.04 683). Conclusion Autophagy is found in PBMCs of SLE, and the autophagy is correlated with renal damage and inflammation in patients with lupus nephritis.

Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF's anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.
