Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment, diet, and lifestyle, which is closely related to many diseases in modern medicine, such as hyperlipidemia, obesity, fatty liver, atherosclerosis, metabolic syndrome, and cardiovascular and cerebrovascular diseases, with a wide range of influence and far-reaching harm. According to the Huangdi Neijing, lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids, which has the function of nourishing, and it is the initial state and source of important substances in the human body such as brain, marrow, essence, and blood. Once the grease of the human body is abnormal, it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach, which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments, leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity, which accumulates in the body's meridians, blood vessels, skin pores, and organs, forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays, it was divided into four common pathogenesis types: ''inability to distinguish between the clear and turbid, turbid stagnation in the Ying blood'', ''spleen not rising clear, turbid accumulation in the vessels'', ''spleen dysfunction, lipid retention in the pores'', ''spleen failure to transportation and transformation, and grease accumulation in the liver''. According to the pathogenesis, it could be divided into four common syndromes, namely, turbid stagnation in the Ying blood, turbid accumulation in the vessels, lipid retention in the pores, and grease accumulation in the liver, and the corresponding prescriptions were given for syndrome differentiation and treatment, so as to guide clinical differentiation and treatment of the lipid turbidity disease.

ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study, hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine (TCM) from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally, 162 valid cases were included, encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets, and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery, blood lipid levels, TCM syndrome distribution, efficacy in terms of TCM syndrome, and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery, the total response rate in the observation group was 86.36% (76/88) and that in the control group was 86.49% (64/74), with no statistically significant difference between the two groups. After treatment, both groups showed declines in levels of triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.05) and elevations in the level of high-density lipoprotein cholesterol (HDL-C) (P<0.05). Moreover, the observation group outperformed the control group in recovering the levels of TG, LDL-C, and HDL-C (P<0.05, P<0.01). In terms of TCM syndrome, hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% (55/63), which was higher than that (63.46%, 33/52) in the control group (χ2=9.102, P<0.01). After treatment, the scores of total TCM symptoms, primary symptoms, and secondary symptoms decreased in both groups (P<0.05), and the observation group had lower scores than the control group (P<0.01). The observation group was superior to the control group in alleviating obesity, chest tightness, and low food intake (P<0.05). In terms of safety, the level of aminotransferase was slightly elevated in the control group, and no obvious adverse reaction was observed in the observation group, with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

ObjectiveTo observe the efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia (syndrome of phlegm turbidity and obstruction) complicated with carotid atherosclerosis. MethodsA total of 120 patients with hyperlipidemia (syndrome of phlegm turbidity and obstruction) complicated with carotid atherosclerosis were randomly allocated into a treatment group and a control group, with 60 patients in each group. The control group orally took rosuvastatin calcium tablets, 10 mg each time, once a day. The treatment group took Zhuyuwan granules, 1 dose a day in 3 times. Both groups received diet and exercise guidance and were treated for 24 consecutive weeks. The traditional Chinese medicine (TCM) symptom scores were recorded before and after treatment. The levels of blood lipids [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)], carotid color ultrasound [carotid intima-media thickness (IMT), plaque number, maximum plaque area, and maximum plaque thickness], vascular intimal repair-related factors [nitric oxide (NO), endothelin-1 (ET-1), soluble intercellular adhesion molecule 1 (sICAM-1), and thromboxane B2 (TXB2)], and oxidative stress-related indicators [superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px)] were measured before and after treatment. The occurrence of adverse reactions was observed during treatment, and the clinical efficacy of the two groups was compared after treatment. ResultsThe trial was completed and 112 patients (57 in the treatment group and 55 in the control group) were included in the statistical analysis, and the general information of the two groups was comparable. The total response rate in the treatment group was 87.72% (50/57), which was higher than that (74.55%, 41/55) in the control group (χ2=4.823, P<0.05). After treatment, the scores of main TCM symptoms such as body obesity, chest tightness, and limb numbness, the scores of secondary symptoms such as palpitation, insomnia, tastelessness in the mouth, reduced appetite, tongue and pulse manifestation scores, and the total TCM symptom score decreased in both groups (P<0.05, P<0.01). Moreover, the treatment group had lower scores of main symptoms such as body obesity, head heaviness, chest tightness, nausea, salivation, and limb numbness, scores of secondary symptoms such as tastelessness in the mouth and reduced appetite, and total TCM symptom score than the control group (P<0.05, P<0.01). After treatment, both groups showed declines in TC, TG, LDL-C, IMT, plaque number, maximum plaque area, maximum plaque thickness, ET-1, sICAM-1, and TXB2 (P<0.05, P<0.01) and elevations in levels of HDL-C, NO, and SOD (P<0.05, P<0.01). The treatment group had lower TC, TG, LDL-C, IMT, plaque number, maximum plaque area, maximum plaque thickness, ET-1, sICAM-1, and TXB2 (P<0.01) and higher levels of HDL-C, NO, SOD, and GSH-Px (P<0.05, P<0.01) than the control group. During treatment, adverse reactions occurred in 3 cases (5.26%, 1 case of dizziness, 1 case of acid reflux, and 1 case of constipation) in the treatment group and 4 cases (7.27%, 2 cases of upper respiratory tract infection, 1 case of abdominal pain, and 1 case of low back pain) in the control group. ConclusionZhuyuwan can effectively reduce blood lipid levels, inhibit the formation of carotid atherosclerotic plaque, and alleviate the syndrome of phlegm turbidity and obstruction by promoting vascular intima repair and improving the antioxidant function.

OBJECTIVE:
To observe the effects of moxibustion at different temperatures on cognitive function and blood glucose levels in patients with cognitive impairment associated with type 2 diabetes mellitus (T2DM).
METHODS:
A total of 66 T2DM patients with cognitive impairment were randomly assigned to a high-temperature group (22 cases, 1 case dropped out, 1 case was eliminated), a medium-temperature group (22 cases, 2 cases were eliminated), and a low-temperature group (22 cases, 2 cases were eliminated). All groups received moxibustion at Baihui (GV20), Dazhui (GV14), and Shenting (GV24) based on their existing glycemic control treatment. Moxibustion temperatures were maintained at 44-46 ℃ (high-temperature group), 41-43 ℃ (medium-temperature group), and 38-40 ℃ (low-temperature group), respectively, for 20 min per session, every other day, 3 times a week for 3 months. The Montreal cognitive assessment (MoCA) score, mini-mental state examination (MMSE) score, short-term memory (STM) accuracy and average reaction time, Rey-Osterrieth complex figure (ROCF) score, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) were assessed before and after treatment. Clinical efficacy was evaluated after treatment.
RESULTS:
After treatment, MMSE scores in all three groups were higher than those before treatment (P<0.05). In the high-temperature group, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, naming, language, and abstraction were higher than those before treatment (P<0.05); the scores of ROCF copy, immediate recall, and delayed recall were higher than those before treatment (P<0.05); the HbA1c level was lower than that before treatment (P<0.05). In the medium-temperature group, the total MoCA score and the scores of memory and delayed recall, attention, and language were higher than those before treatment (P<0.05). STM accuracy was higher than before treatment (P<0.05), and STM average reaction time was shorter than before treatment (P<0.05) in both the high-temperature and medium-temperature groups. After treatment, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, and language in the high-temperature group were higher than those in the medium- and low-temperature groups (P<0.05); MMSE score, STM accuracy, and ROCF immediate recall and delayed recall scores were higher than those in the medium- and low-temperature groups (P<0.05); STM average reaction time was shorter than that in the medium- and low-temperature groups (P<0.05); HbA1c level was lower than that in the low-temperature group (P<0.05). The total MoCA score, attention score, and MMSE score in the medium-temperature group were higher than those in the low-temperature group (P<0.05), and STM average reaction time was shorter than that in the low-temperature group (P<0.05). There were no statistically significant differences in FPG within or between the three groups before and after treatment (P>0.05). The total effective rates were 75.0% (15/20) in the high-temperature group, 50.0% (10/20) in the medium-temperature group, and 15.0% (3/20) in the low-temperature group; the total effective rate in the high-temperature group was significantly higher than that in the low-temperature group (P<0.05).
CONCLUSION
Moxibustion at different temperatures has a dose-effect relationship in treating cognitive impairment in T2DM patients. A temperature range of 44-46 ℃ is more effective in improving cognitive function and stabilizing average blood glucose levels over 2-3 months.

To assess the implantation effectiveness of porous scaffolds, it is essential to consider not only their mechanical properties but also their biological performance. Given the high cost, long duration and low reproducibility of biological experiments, simulation studies as a virtual alternative, have become a widely adopted and efficient evaluation method. In this study, based on the secondary development environment of finite element analysis software, the strain energy density growth criterion for bone tissue was introduced to simulate and analyze the cell proliferation-promoting effects of four different lattice porous scaffolds under cyclic compressive loading. The biological performance of these scaffolds was evaluated accordingly. The computational results indicated that in the early stages of bone growth, the differences in bone tissue formation among the scaffold groups were not significant. However, as bone growth progressed, the scaffold with a porosity of 70% and a pore size of 900 μm demonstrated markedly superior bone formation compared to other porosity groups and pore size groups. These results suggested that the scaffold with a porosity of 70% and a pore size of 900 μm was most conducive to bone tissue growth and could be regarded as the optimal structural parameter for bone repair scaffold. In conclusion, this study used a visualized simulation approach to pre-evaluate the osteogenic potential of porous scaffolds, aiming to provide reliable data support for the optimized design and clinical application of implantable scaffolds.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.
