Integrative analysis and identification of key elements and pathways regulated by Traditional Chinese Medicine (Yiqi Sanjie formula) in colorectal cancer.

Introduction: The clinical efficacy of Yiqi Sanjie (YQSJ) formula in the treatment of stage III colorectal cancer (CRC) has been demonstrated. However, the underlying antitumor mechanisms remain poorly understood. Materials and methods: The aim of the present study was to comprehensively characterize the molecular and microbiota changes in colon tissues and fecal samples from CRC mice and in CRC cell lines treated with YQSJ or its main active component, peiminine. Integrative tandem mass tag-based proteomics and ultra-performance liquid chromatography coupled with time-of-flight tandem mass spectrometry metabolomics were used to analyze azoxymethane/dextran sulfate sodium-induced CRC mouse colon tissues. Results: The results showed that 0.8% (57/7568) of all detected tissue proteins and 3.2% (37/1141) of all detected tissue metabolites were significantly changed by YQSJ treatment, with enrichment in ten and six pathways associated with colon proteins and metabolites, respectively. The enriched pathways were related to inflammation, sphingolipid metabolism, and cholesterol metabolism. Metabolomics analysis of fecal samples from YQSJ-treated mice identified 121 altered fecal metabolites and seven enriched pathways including protein digestion and absorption pathway. 16S rRNA sequencing analysis of fecal samples indicated that YQSJ restored the CRC mouse microbiota structure by increasing the levels of beneficial bacteria such as Ruminococcus_1 and Prevotellaceae_UCG_001. In HCT-116 cells treated with peiminine, data-independent acquisition-based proteomics analysis showed that 1073 of the 7152 identified proteins were significantly altered and involved in 33 pathways including DNA damage repair, ferroptosis, and TGF-ß signaling. Conclusion: The present study identified key regulatory elements (proteins/metabolites/bacteria) and pathways involved in the antitumor mechanisms of YQSJ, suggesting new potential therapeutic targets in CRC.

Effect of Huaji Jianpi Decoction on the semen quality of high-fat diet-induced obese mice.

Background: At present, the incidence of obesity is increasing. Several studies have shown that obesity can reduce male fertility by affecting spermatogenesis and semen quality. Traditional Chinese medicine (TCM) has fewer side effects and stable efficacy in the treatment of related diseases. This study aimed to investigate the effect of Huaji Jianpi Decoction on the semen quality of high-fat diet-induced obese mice. Methods: The obese male mice model was constructed by using high-fat diet and the Huaji Jianpi Decoction was processed into an aqueous extract. Mice were allocated in the normal group (n=30) and five different treatment groups (n=50). Huaji Jianpi Decoction was applied in low-, medium- and high-dose [17.52 g/(kg·d), 35.04 g/(kg·d) and 70.07 g/(kg·d), respectively]. The body weight, body fat, testis wet weight, testis coefficient, and routine sperm parameters were detected and analyzed. Meanwhile, transmission electron microscope (TEM) was used to observe testis ultrastructure. reverse-transcription quantitative PCR (RT-qPCR) was used to measure the expression of tumour necrosis factor α (TNF-α) and monocyte chemoattractant protein-1 (MCP-1). Results: Compared with normal mice (ND), the testis wet weight and testis coefficient of mice in the blank group were significantly decreased, while the number of mitochondria was observed to be decreased on testis ultrastructure examination, and apoptotic cells and germ cells in the spermatogenic tubules were shed. After Huaji Jianpi Decoction administration, the body fat and blood lipid levels of obese mice were decreased, the testis wet weight and testis coefficient were increased, and semen parameters were increased. Different doses of Huaji Jianpi Decoction could improve testicular weight, sperm density, sperm motility, forward motility, and total sperm motility. Huaji Jianpi Decoction could also downregulate TNF-α and MCP-1 expression and inhibit germ cell apoptosis to improve semen quality. Conclusions: Huaji Jianpi Decoction can improve the semen quality of high-fat diet-induced obese mice by reducing weight and lipid levels.

Angiogenesis and Hepatic Fibrosis: Western and Chinese Medicine Therapies on the Road.

Hepatic fibrosis is a common feature of almost all chronic liver diseases. Formation of new vessels (angiogenesis) is a process strictly related to the progressive fibrogenesis which leads to cirrhosis and liver cancer. This review mainly concerns the relationship between angiogenesis and hepatic fibrosis, by considering the mechanism of angiogenesis, cells in angiogenesis, anti-angiogenic and Chinese medicine therapies.

[Research progress in obesity-induced low fertility in males].

The prevalence of obesity in men of reproductive age is globally increasing. Obesity alters the ratio of testosterone to estradiol and the homeostasis of leptin and other hormone levels by interfering with the hypothalamus-pituitary-gonadal axis. In addition, it may change epigenetic modifications and intergenerational transmission, which would affect the health of the offspring. Both of the pathways reduce male fertility, which may be associated with the obesity-induced change in the levels of some hormones and consequently the alteration of epigenetic modifications. This review focuses on the adverse effects of obesity on male fertility by influencing endocrine hormones and epigenetic modifications, and further discusses the effects of endocrine hormones on male fertility by epigenetic modification, aiming to provide some basic data for the prevention and treatment of obesity-related male fertility in clinical practice.

Transarterial chemoembolization combined with Jie-du granule preparation improves the survival outcomes of patients with unresectable hepatocellular carcinoma.

The aim of the present study was to compare the effectiveness of transarterial chemoembolization (TACE), TACE combined with Jie-du granules (JD), and TACE combined with sorafenib (SOR) for treating patients with unresectable hepatocellular carcinoma (HCC). For this purpose, we conducted a retrospective analysis of data from 266 consecutive patients with unresectable HCC who underwent TACE treatment at the Shanghai Hospital and Eastern Hepatic Surgery Hospital between Jan 2009 and Dec 2010. We prospectively analyzed patient survival and progression times as well as independent predictors, within a follow-up period of 86 months. Patients were divided into TACE-JD (n = 75), TACE-SOR (n = 124) and TACE (n = 67) groups. Median overall survival (OS) times being: TACE-JD, 21.43 months; TACE-SOR, 23.23 months; TACE, 13.97 months (TACE-SOR vs TACE, P < 0.001; TACE-SOR vs TACE-JD, P = 0.852; TACE-JD vs TACE, P < 0.001). The median times to progression (TTP) were as follows: TACE-JD, 8.67 months; TACE-SOR, 5.37 months; TACE, 4.57 months (TACE-SOR vs TACE, P = 0.479; TACE-SOR vs TACE-JD, P < 0.001; TACE-JD vs TACE, P < 0.001). Independent predictors of OS were treatment allocation, Child-Pugh class large tumor, albumin and extrahepatic metastasis. These findings show that patients with unresectable HCC who were administered TACE-JD survived significantly longer compared with those administered TACE or TACE-SOR.

Sang-qi Granula Reduces Blood Pressure and Myocardial Fibrosis by Suppressing Inflammatory Responses Associated with the Peroxisome Proliferator-Activated Receptors and Nuclear Factor κ B Protein in Spontaneously Hypertensive Rats.

Aim. Sang-qi Granula (SQ) is a compound prepared from Chinese herbs and is currently used for treatment of hypertension in China. Given its protective effects on cardial function in decreasing blood pressure, we investigated the mechanism of protective effects of SQ on myocardium. Methods. 16 male normal Wistar-Kyoto rats and 16 spontaneous hypertension rats (SHR) were employed without medical treatment. 16 SHR were employed with SQ treatment. Rats in each group were sacrificed at two time points (8-week treatment and 16-week treatment). Blood pressure (BP), and heart weight/body weight (HW/BW) were measured. The expression of myeloperoxidase (MCP-1), ICAM-1, TNF- α , and CD68-positive cells was assessed. The interstitial collagen volume fraction (CVF), perivascular collagen volume area (PVCA), and the expression of TGF- ß , Smad-3, PPAR α , γ , and NF- κ B (P65 and P50) were observed. Results. SQ significantly inhibited the elevation of the blood pressure and HW/BW of SHR. Next, SQ prevented myocardial fibrosis. Finally, a proinflammatory mediator associated with NF- κ B (TNF- α , ICAM-1, MCP-1, CD68), TGF- ß , and Smad-3 related to collagen deposition, which is upregulated in SHR group, was significantly suppressed by SQ. Expression of NF- κ B was decreased in SHQ+SQ group compared to PPAR α , and γ expression was increased by SQ. Conclusion. Treatment with SQ ameliorates cardial fibrosis induced by hypertension by attenuating the upregulation of ICAM-1, TNF- α , MCP-1, TGF- ß , Smad-3, P65, and P50 expression and improving PPAR α and PPAR γ expression level. The results suggest that SQ may be an option for preventing cardial fibrosis through PPAR signalling pathway.
