ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan(RYZBW)in the treatment of initial and early knee osteoarthritis (KOA) through a prospective multicenter,randomized,double-blind,and placebo-parallel controlled trial. MethodFrom October 13th, 2021 to December 25th, 2021, 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital, Chinese Academy of Chinese Medical Sciences, and they were randomly divided into observation group and control group, with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education, and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks, and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score (WOMAC score), and the secondary outcome measures were the response rate of visual scale (VAS) pain score, WOMAC sub item scores (joint pain, joint stiffness, and joint function), quality of life (SF-12) score, and traditional Chinese medicine (TCM) syndrome score. Result(1) Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW, and the difference was statistically significant (P<0.05). There was no significant difference between the two groups in improving VAS score response rate, WOMAC function score, WOMAC stiffness score, SF12-PCS (quality of life-physical health) score, SF12-MCS (quality of life-mental health) score, and TCM syndrome score. (2) Subgroup analysis. ① In terms of VAS score response rate, the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of (4, 5], and the difference was statistically significant (P<0.05). ② In terms of TCM syndrome score, for subjects aged [56, 60] and [61, 65], the decrease in total TCM syndrome score in the observation group was better than that in the control group, and the difference was statistically significant (P<0.05). ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score, VAS score response rate, WOMAC pain score, WOMAC function score, and TCM syndrome score for patients with initial and early KOA, which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

ObjectiveTo investigate the therapeutic effect of ganoderic acid A (GA-A) on a mouse model of concanavalin A (ConA)-induced autoimmune hepatitis (AIH). MethodsA total of 35 mice were randomly divided into control group (NC group), model group (ConA group), and low-, middle-, and high-dose GA-A treatment groups (GA-A-L, GA-A-M, and GA-A-H groups, respectively), with 7 mice in each group. ConA was injected via the caudal vein of mice to establish a classic mouse model of AIH, and different doses of GA-A were administered via intraperitoneal injection 1 hour later for treatment. Proteomic techniques were used to investigate the protective mechanism of GA-A on hepatocytes, and HL-60 cells were differentiated into dHL-60 neutrophils by all-trans retinoic acid in vitro to validate the mechanism of action of GA-A. Related indicators were measured, including inflammatory markers (the activities of serum alanine aminotransferase [ALT] and aspartate aminotransferase [AST], HE staining, and inflammation-related genes), apoptosis markers (TUNEL staining), neutrophils, and neutrophil extracellular trap (NET) markers (myeloperoxidase [MPO], citrullinated histone H3 [CitH3], Ly6G, and free double-stranded DNA [dsDNA]), and p38 phosphorylation markers. The independent samples t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the NC group, the ConA group had significant increases in the serum levels of ALT and AST (both P<0.001), and compared with the ConA group, GA-A treatment significantly reduced the levels of ALT and AST (both P<0.01). HE staining showed that the mice in the ConA group had significant liver necrosis, while GA-A treatment significantly reduced the area of liver necrosis and the number of TUNEL-positive cells (both P<0.05). Compared with the ConA group, the GA-A group had significant reductions in the expression levels of the inflammatory factors interleukin-6, tumor necrosis factor-α, and interferon gamma in serum and liver tissue (all P<0.05). The proteomic analysis showed that GA-A alleviated ConA-induced acute immune liver injury by inhibiting the release of NET and the p38 MAPK pathway. Immunofluorescent staining of mouse liver tissue showed that compared with the ConA group, the GA-A group had significant reductions in the number of MPO-positive neutrophils and the number of cells with positive Ly6G and CitH3 (all P<0.01). Western Blot and dsDNA testing showed that GA-A significantly inhibited the levels of the NET markers dsDNA and CitH3 and the level of p38 phosphorylation in liver tissue and dHL-60 cells (all P<0.05). ConclusionGA-A alleviates liver inflammatory response and hepatocyte death by inhibiting the p38 MAPK pathway and the release of NET, thereby alleviating ConA-induced acute immune liver injury. This study provides a theoretical basis for the use of GA-A to treat immune liver injury by regulating neutrophil function.

OBJECTIVES:
To observe the changes of skin blood flow perfusion at Waiguan (TE 5) caused by mild moxibustion with moxa stick and infrared mild moxibustion using laser speckle contrast imaging technology, and to compare the microcirculatory effect during and after both moxibustion methods and explore the dose-response relationship of moxibustion.
METHODS:
Twenty-four healthy participants were treated with mild moxibustion with moxa stick and infrared mild moxibustion at left Waiguan (TE 5). The record started when the skin temperature reached (44±1) °C, and both moxibustion methods were provided within this temperature range. The 20-minute moxibustion process was divided into four stages (5, 10, 15, and 20 min) using interpolation method, and each participant completed eight interventions with a minimum 24-hour interval between different interventions. The skin surface temperature of the left Waiguan (TE 5) was monitored when both moxibustion interventions were given for 10 min using a TES1306 thermocouple thermometer. The skin microcirculatory blood perfusion units (MBPU) of left Waiguan (TE 5) was measured using a PSIN-01087 laser speckle blood flow imager 1 min before moxibustion, at 5, 10, 15, 20 min during moxibustion and continuously for 20 min after moxibustion in each intervention.
RESULTS:
The skin surface temperature of the left Waiguan (TE 5) remained within the range of (44±1) °C during both moxibustion methods, with no statistically significant difference (P>0.05). Compared with that before moxibustion, the MBPU of the left Waiguan (TE 5) was increased significantly at 5, 10, 15, and 20 min of both moxibustion methods (P<0.05, P<0.01). Compared with moxibustion for 10, 15 and 20 min, the MBPU of the left Waiguan (TE 5) of moxibustion for 5 min was lower in both moxibustion methods (P<0.01). For both moxibustion methods with the same moxibustion course, the MBPU of the left Waiguan (TE 5) 20 min after intervention was significantly higher than that at 1 min before moxibustion (P<0.001), and there was no significant difference in MBPU between 1 min before moxibustion and 20 min after moxibustion among different groups (P>0.05). Within the same moxibustion method, the MBPU of the left Waiguan (TE 5) 20 min after moxibustion with the intervention of 5 min was lower compared to that of 10, 15, and 20 min of moxibustion (P<0.001), with no significant differences between 10, 15, and 20 min of moxibustion (P>0.05).
CONCLUSIONS
When controlling the skin temperature at Waiguan (TE 5) within (44±1) °C, infrared mild moxibustion has similar effects on skin microcirculatory blood perfusion as traditional mild moxibustion with moxa sticks. From a dose-response perspective, microcirculation reached a stable state after 10 min of moxibustion, and moxibustion interventions lasting for more than 10 min shows better therapeutic effects.

ObjectiveTo confirm the clinical efficacy and safety of Yishen Yangxin Anshen tablets in the treatment of insomnia (heart-blood deficiency and kidney-essence insufficiency syndrome). MethodA randomized block, double-blind, placebo-controlled, multi-center clinical trial design method was adopted, and a total of 480 patients with insomnia due to deficiency of heart blood and insufficiency of kidney essence (treatment group-control group 3∶1) from seven hospitals (Guang'anmen Hospital, China Academy of Chinese Medical Sciences, The First Clinical Hospital, Jilin Province Academy of Traditional Chinese Medicine(TCM), The Second Affiliated Hospital of Liaoning University of TCM, The First Affiliated Hospital of Henan University of Chinese Medicine, Henan Province Hospital of TCM, Hebei General Hospital, The First Hospital of Hunan University of Chinese Medicine) were enrolled. The treatment group was given Yishen Yangxin Anshen tablets and the control group received placebo tablets (4 tablets/time, 3 times/day, 4 weeks of administration, 4 weeks of follow-up after drug withdrawal). The sleep dysfunction rating scale (SDRS) score, pittsburgh sleep quality index (PSQI) score, TCM, polysomnography (PSG) indicators from four hospital (Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Henan Province Hospital of TCM, Hebei General Hospital, The First Hospital of Hunan University of Chinese Medicine), and other efficacy indicators were compared between the two groups before and after treatment. Through general physical examination, laboratory examination, and observation of adverse events, the safety of the drugs was evaluated. ResultThe baseline indexes of the two groups showed no significant difference and thus the two groups were comparable. After treatment, the total score of SDRS in the treatment group was lower than that in the control group (P<0.01). After drug withdrawal for 4 weeks, the total score of SDRS demonstrated no significant change in the treatment group as compared with that at the end of treatment, indicating that the rebound change of curative effect was not obvious. After treatment, the total score of PSQI in the treatment group decreased as compared with that in the control group (P<0.01), and the change of total score of PSQI in the treatment group was statistically significant (P<0.05) after drug withdrawal for 4 weeks but small, indicating that the rebound change of curative effect was not obvious. After treatment, the total effective rate about the TCM symptoms in the treatment group was higher than that in the control group (χ2=137.521,P<0.01). After treatment, the disappearance rates of single indexes in the treatment group, such as difficulty in falling asleep, easily waking up after sleeping, early awakening, short sleep time, dreamfulness, palpitation, forgetfulness, dizziness, mental fatigue, and weakness of waist and knee, increased compared with those in the control group (P<0.01). After treatment, the treatment group demonstrated fewer awaking times (AT), longer total sleep time (TST), lower ATA/TST ratio, and higher sleep efficiency (%) than the control group (P<0.05). No abnormal value or aggravation related to drugs was observed in either group. The incidence of adverse events in the treatment group and the control group was 5.57% and 8.40% respectively. No serious adverse events or adverse events leading to withdrawal happened in either group. ConclusionYishen Yangxin Anshen tablets is effective and safe for patients with insomnia of deficiency of heart-blood and insufficiency of kidney-essence.

T cells play central roles in anti-tumor immune responses. Immune checkpoint therapy, which is based on modulation of T cell reactivity, has achieved breakthrough in clinical treatment of multiple tumors. Moreover, adoptive T cell therapy, which includes mainly genetically engineered T cells, has shown substantial treatment efficacy in hematoma. Immune therapy has tremendously changed the scenario of clinical tumor treatment and become critical strategies for treating multiple tumors. T cell receptor (TCR) is the fundamental molecule responsible for the specificity of T cell recognition. TCRs could recognize peptides, which are derived from intracellular or extracellular tumor antigens, presented by major histocompatibility complex (MHC) and are therefore highly sensitive to low antigen level. Thereby, TCRs are broadly recognized as promising molecules for the development of anti-tumor drugs. The approval of the first TCR drug in 2022 has initiated a new era for TCR-based therapeutics and since then, multiple TCR drugs have shown substantial treatment efficacy in multiple tumors. This review summarizes the progress of TCR-based immune therapeutic strategies, including T cell receptor-engineered T cell (TCR-T), TCR-based protein drugs, and other cell therapies based on TCR signaling, providing useful information for future design of immune therapeutics based on TCR.

Diabetic nephropathy (DN) is a common clinical complication of diabetes, the main cause of end-stage renal disease (ESRD), and a key determinant of survival in diabetic patients. The pathogenesis of DN is complex, and it is currently believed to be associated with hemodynamic abnormalities, intestinal flora disturbances, glucose and lipid metabolism disorders, oxidative stress, genetic susceptibility, and protein non-enzymatic glycosylation. The local renin-angiotensin system (RAS) has always been the core of the pathogenic and progressive changes of DN. Once activated, it will induce the massive release of oxygen free radicals in the blood vessels, damage the endothelial function, and affect the microcirculation of the body. The recent studies demonstrate that intestinal flora and its metabolites may affect the occurrence and development of DN by activating or antagonizing the local RAS. Compared with western medicine treatment, traditional Chinese medicine (TCM) has the advantages of multiple targets and little toxic and side effects. Many TCM scholars have found that single herbs, their active ingredient extracts, and TCM compound prescriptions can improve kidney function by regulating the local RAS or intestinal flora. Specifically, the Chinese medicinal materials tonifying spleen (Codonopsis Radix, Dioscoreae Rhizoma, Atractylodis Macrocephalae Rhizoma, and Poria), replenishing kidney (Rehmanniae Radix Praeparata, Corni Fructus, and Pseudostellariae Radix), and activating blood, resolving stasis, and dredging collaterals (Hirudo, Salviae Miltiorrhizae Radix et Rhizoma, and Angelicae Sinensis Radix) have the regulatory effect. This article summarizes the roles of intestinal flora and local RAS in the occurrence and development of DN, and analyzes the animal experiments or clinical trials of TCM intervention in DN in recent years, aiming to provide more therapies and a theoretical basis for the treatment of DN with integrated TCM and Western medicine.

ObjectiveTo observe the effect of comprehensive intervention on the incidence of lactation galactostasis in communities from the perspective of preventive medicine, so as to prevent the occurrence of the mammary ducts obstruction disease. MethodsA total of 400 women in the early stage of pregnancy were selected from four communities. Those in two communities were set up as the intervention group. Comprehensive intervention for the prevention and treatment of mammary ducts obstruction disease during pregnancy and "Six-step recanalization manual therapy" practical guidance were conducted on the intervention group. The pregnant women from the other two communities were the control group, who received no intervention or guidance training. The two groups were followed up at 1 month, 3 months and 5 months postpartum, and the occurrence of mammary ducts obstruction disease was investigated and interventions were carried out. ResultsThe incidence of galactostasis in the intervention group was 26.0%, 10.6% and 5.1%, respectively at 1, 3 and 5 months after delivery, and the incidence of galactostasis in the control group was 38.0%, 22.2% and 8.3%, respectively. The incidence of galactostasis at 1 month and3 months after delivery was statistically different (P<0.05), while the incidence of galactostasis 5 months after delivery was not statistically different (P>0.05). The protection rates of comprehensive intervention on galactostasis were 31.58%, 52.25% and 38.55%, respectively. ConclusionPublicity and education work of prevention and control of the mammary ducts obstruction disease and "Six-step recanalization manual therapy" practical guidance can effectively reduce the occurrence of plugged mammary ducts, and therefore should be promoted.
