ABSTRACT
Exercise fatigue is a normal protective mechanism of the body. However, long-term fatigue hinders normal metabolism and exercise capacity. The generation and recovery from exercise fatigue involves alterations in multiple signaling pathways, mainly AMPK, PI3K/Akt, Nrf2/ARE, NF-κB, PINK1/Parkin, and BDNF/TrkB, as well as MAPK signaling pathways that mediate energy supply, reduction of metabolites, oxidative stress homeostasis, muscle fiber type switching, and central protective effects. In recent studies, a rich variety of natural active ingredients have been identified in traditional Chinese medicines and plant extracts with anti-fatigue effects, opening up the field of research in new anti-fatigue drugs. In this review we give an overview of the signaling pathways associated with the activity of natural food active ingredients against exercise fatigue. Such a comprehensive review is necessary to understand the potential of these materials as preventive measures and treatments of exercise fatigue. We expect the findings highlighted and discussed here will help guide the development of new health products and provide a theoretical and scientific basis for future research on exercise fatigue.
ABSTRACT
The academic thoughts of professor GAO Wei-bin regarding the use of electroacupuncture in the treatment of dry eye are introduced. Professor GAO believes that the occurrence of dry eye is mainly related to the stagnation of qi and blood in the eye meridians, leading to inadequate nourishment of the eyes. The acupuncture treatment principle focuses on promoting blood circulation, clearing and benefiting the eye orifices. By integrating traditional acupuncture theory with modern neuroanatomy, the treatment approach centers on stimulating the lacrimal gland, emphasizing the importance of promoting, addressing symptoms as a priority, and considering both the root cause and symptoms.The precise acupoint selection is emphasized. Acupoints of periocular region, such as Taiyang (EX-HN 5) and Leixian point are selected along with Fengchi (GB 20) and Gongxue point to treat dry eye. Attention is also given to the use of electroacupuncture and the selection of its frequencies, emphasizing specific needling techniques based on the severity and classification of the disease.

Objective: Yinchen Sini decoction (YCSND), a traditional Chinese medicine (TCM) formula, plays a crucial role in the treatment of liver disease. However, the bioactive constituents and pharmacological mechanisms of action remain unclear. The present study aimed to reveal the molecular mechanism of YCSND in the treatment of acute liver injury (ALI) using integrated network analysis and metabolomics. Methods: Ultra-high-performance liquid chromatography coupled with Q-Exactive focus mass spectrum (UHPLC-QE-MS) was utilized to identify metabolites in YCSND, and high-performance liquid chromatography (HPLC) was applied to evaluate the quality of four botanical drugs in YCSND. Cell damage and ALI models in mice were established using CCl4. 1H-NMR metabolomics approach, along with histopathological observation using hematoxylin and eosin (H&E), biochemical measurements, and reverse transcription quantitative real-time PCR (RT-qPCR), was applied to evaluate the effect of YCSND on CCl4- induced ALI. Network analysis was conducted to predict the potential targets of YCSND in ALI. Result: Our results showed that 89 metabolites in YCSND were identified using UHPLC-QE-MS. YCSND protected against ALI by reducing the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and malondialdehyde (MDA) contents and increasing those of superoxide dismutase (SOD), and glutathione (GSH) both in vivo and in vitro. The 1H-NMRmetabolic pattern revealed that YCSND reversed CCl4-induced metabolic abnormalities in the liver. Additionally, the Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment analysis identified five pathways related to liver injury, including the PI3K-AKT, MAPK, HIF-1, apoptosis, and TNF signaling pathways. Moreover, RT-qPCR showed YCSND regulated the inflammatory response (Tlr4, Il6, Tnfα, Nfκb1, Ptgs2, and Mmp9) and apoptosis (Bcl2, Caspase3, Bax, and Mapk3), and inhibited PI3K-AKT signaling pathway (Pi3k and Akt1). Combined network analysis and metabolomics showed a link between the key targets (Tlr4, Ptgs2, and Mmp9) and vital metabolites (choline, xanthine, lactate, and 3-hydroxybutyric acid) of YCSND in ALI. Conclusion: Overall, the results contribute to the understanding of the therapeutic effects of YCSND on ALI, and indicate that the integrated network analysis and metabolomics could be a powerful strategy to reveal the pharmacological effects of TCM.
ABSTRACT
Acupuncture therapy has been widely used in clinical treatment of allergic rhinitis (AR), and can induce a positive therapeutic effect through multi-targets and multi-aspects. In recent 10 years, the research on the mechanisms of acupuncture in treating AR mainly focused on humoral immunity, cellular immunity, cell apoptosis, inflammatory mediators and factors, neuropeptides, etc. By regulating the level of immunoglobulin in the blood, acupuncture intervention can restore the relative balance of cellular immune response, reduce the accumulation of eosinophils and promote apoptosis, down-regulate the expression of related inflammatory mediators and factors, regulate the excitability of related nerves, modulate the release of neuropeptides and other ways to diminish the inflammatory reaction of nasal mucosa, and enhance the repair and protection of nasal mucosa, relieve the nasal symptoms at last. On the basis of the existing studies, the follow-up research should make use of the advantages of acupuncture intervention, refine the treatment process, and deeply explore the feasibility of acupuncture treatment of AR, further promote the combination of mechanism study and clinical practice, provide references for clinical application. Moreover, some shortcomings exist, for example, the unknown correlation between the therapeutic effect and duration of treatment, the unknown correlation between the effect of acupuncture and various targets, and disconnection between experimental research achievements and clinical application, etc.

There is a lot of evidence that oral hypoglycemic drugs work by affecting gut microbes, but the key strains responsible for this effect are not well known. Huang-Qi-Ling-Hua-San (HQLHS), composed of Astragalus Membranaceus, Ganoderma lucidum, Inonotus obliquus, and Momordica charantia L., is a specially designed Chinese medicine formula to treat type 2 diabetes (T2D). In this study, a mouse model of T2D induced by high-fat diet and streptozotocin was used to explore the mechanism of HQLHS in improving hyperglycemia and hyperlipidemia through multiple rounds of animal experiments, such as HQLHS feeding, fecal microbiota transplantation (FMT), and live bacteria feeding, so as to explore the potential target intestinal flora in its hypoglycemic effect. Results show that such specific taxa as Bifidobacterium, Turicibacter, Alistipes, Romboutsia, and Christensenella were identified to be preferably enriched by HQLHS and then assumed to be the target microbes. Herein, FMT was used to test if the upregulated beneficial bacteria by HQLHS play a therapeutic role. The strain Christensenella minuta DSM 22607 and the strain Christensenella timonensis DSM 102800 were selected to test the beneficial effect of Christensenella taxa on T2D. Diabetic animals supplemented with these strains showed the improvement in blood glucose and lipid metabolism, the promotion of GLP-1 secretion, the increase in antioxidant capacity, the inhibition of hepatic gluconeogenesis, the suppression of intestinal glucose absorption, the enhancement of intestinal barrier, reduced LPS-induced inflammation, and the reduction of branched amino acids (BCAAs) content in the liver. Overall, these data demonstrate that Christensenella plays a beneficial role in T2D and is a target for the action of HQLHS therapy.
ABSTRACT
Intense and excessive exercise-induced fatigue has become an important health issue and can damage intestinal health. Deer blood, as a food byproduct with nutritional value, has been found to restore physical strength. However, little is known about the antifatigue effect of fermented deer blood (FDB) on intense exercise mice. The purpose of the present study is to investigate the antifatigue effect of FDB, and whether this effect is correlated with the altered small intestinal microbiota and metabolites in exercise mice. In this study, 5-week-old male C57BL/6J mice are given treadmill exercise with or without FDB supplementation (30 and 150 mg/kg/d) for 3 weeks. FDB significantly reduces metabolic byproduct accumulation, liver and intestinal damage, and enhances glycogen storage and antioxidant capacity in intense exercise mice. Moreover, FDB restructures the small intestinal microbiota by increasing the abundance of probiotics and butyric acid producing bacteria and decreasing the abundance of pathogenic bacteria. FDB also regulates the levels of metabolites involved in TCA cycle and amino acid metabolism in urine and small intestine content. Correlation analysis shows that FDB-modulated microbiota is highly associated with its antifatigue effect. FDB may ameliorate fatigue and intestinal injury through targeting small intestinal microbiota.

Inflammatory response during myocardial ischemia reperfusion injury (MIRI) is essential for cardiac healing, while excessive inflammation extends the infarction and promotes adverse cardiac remodeling. Understanding the mechanism of these uncontrolled inflammatory processes has a significant impact during the MIRI therapy. Here, we found a critical role of ATP-sensitive potassium channels (KATP) in the inflammatory response of MIRI and its potential mechanism and explored the effects of Panax Notoginseng Saponins (PNS) during this possess. Rats underwent 40 min ischemia by occlusion of the left anterior descending (LAD) coronary artery and 60 min of reperfusion. PNS was treated at the corresponding time point before operation; 5-hydroxydecanoate (5-HD) and glybenclamide (Gly) (or Nicorandil (Nic)) were used as pharmacological blocker (or nonselective opener) of KATP. Cardiac function and pathomorphology were evaluated and a set of molecular signaling experiments was tested. KATP current density was measured by patch-clamp. Results revealed that in MIRI, PNS pretreatment restored cardiac function, reduced infarct size, and ameliorated inflammation through KATP. However, inhibiting KATP by 5-HD and Gly significantly reversed the effects, including NLRP3 inflammasome and inflammatory mediators IL-6, MPO, TNF-α, and MCP-1. Moreover, PNS inhibited the phosphorylation and nuclear translocation of NF-κB in I/R myocardium when the KATP was activated. Importantly, PNS promoted the expression of subunits and activation of KATP. The study uncovered KATP served as a new potential mechanism during PNS modulating MIRI-induced inflammation and promoting injured heart recovery. The manipulation of KATP could be a potential therapeutic approach for MIRI and other inflammatory diseases.

Carbon monoxide (CO) has been the leading cause of poisoning mortality in many countries and hyperbaric oxygen (HBO) is a widely accepted treatment for CO poisoning. However, some patients with CO poisoning will still develop neurocognitive sequelae regardless of HBO therapy, which can persist since CO poisoning or be present days to weeks after a recovery from CO poisoning. HBO has been used in the prevention and treatment of neurocognitive sequelae after CO poisoning, and some mechanisms are also proposed for the potential neuroprotective effects of HBO on the neurocognitive impairment after CO poisoning, but there is still controversy on the effectiveness of HBO on neurocognitive sequelae after CO poisoning. In this paper, we briefly introduce the neurocognitive sequelae after CO poisoning, summarize the potential predictive factors of neurocognitive sequelae, and discuss the use of HBO in the treatment and prevention of neurocognitive sequelae after CO poisoning.

The potential of probiotics for treating ulcerative colitis (UC) has attracted increasing attention. However, more studies are still needed to guide physicians on the proper selection and use of probiotics. Here, we propose that combination of multiple probiotics with different functions can reduce intestinal inflammation. In this study, the effects of probiotics (Lactobacillus reuteri, Bacillus coagulans, Bifidobacterium longum, and Clostridium butyricum) on the physiology and histopathology of colon were evaluated in a dextran sulfate sodium (DSS)-induced colitis mouse model. The combined species, as well as the species individually, were tested and compared with sulfasalazine (SASP) and two Chinese herbal therapies. Results show that the functions of the four probiotic strains were different in regulating intestinal immunity and barrier function. The four-species probiotic cocktail was more effective than the species individually and anti-inflammatory drugs in repairing the dysbiosis of mucosal microbial ecology and reducing intestinal inflammation. The multi-strain probiotic mixture increased the proportion of beneficial bacteria and decreased the proportion of pro-inflammatory bacteria in the colonic mucosa. In addition, probiotic mixture significantly enhanced the expression of IL-10 and intestinal barrier function. These results suggest that a combination of multiple probiotics with different functions has synergistic effects and can restore the balance of interactions between microorganisms and immunological niches.

Brasenia schreberi (B. schreberi) is a rare and precious vegetable, which coat with a gelatinous mucilage. This study is aiming to investigate the relationship between structural characteristics and hypoglycemic activities of polysaccharides with different molecular weight (Mw) range. Three polysaccharides fractions, namely BSP-U100 (50-100â¯kDa), BSP-U50 (10-50â¯kDa) and BSP-U10 (<10â¯kDa), were isolated from B. schreberi mucilage using ultrafiltration method. Compared to other polysaccharide samples, only BSP-U100 had a triple helix structure and existed as the ordered structure in aqueous solution. Furthermore, BSP-U100 exhibited higher α-amylase (IC50â¯=â¯0.4414â¯mg/mL) and α-glucosidase (IC50â¯=â¯0.5993â¯mg/mL) inhibitory activity. A heteropolysaccharide BSP-1a, which average Mw was 83.98â¯kDa, was purified from BSP-U100 by DEAE Sepharose Fast Flow and Sephadex G-75 column. D-galactose (66.85%), d-glucose (2.05%) and D-mannose (1.65%) were three main monosaccharides of BSP-1a. Structural characterization of BSP-1a showed that BSP-1a might be a kind of L-D-pyranose type galactose and mainly composed of α-1â¯ââ¯6-linked Galp, α-1â¯ââ¯3-linked Manp and α-1â¯ââ¯4-linked Glcp. This study provided a theoretical basis for the development and application of B. schreberi polysaccharides as a potential anti-diabetic supplement.

Colorectal carcinoma (CRC) is one of the most common types of malignant tumor in humans, and its morbidity is on the increase in economically transitioning countries. Due to its high toxicity, the use of the Chinese Traditional Medicine arsenic (As2O3) is limited. However, certain studies have reported that As2O3 induces differentiation of tumor cells, promotes tumor cell apoptosis and inhibits tumor cell proliferation, although the number of studies on the effects of As2O3 on cancer stem cells (CSCs) of CRC is limited. In order to research the effects of different concentrations of As2O3 on CRC cells and colorectal CSCs in vitro, aldehyde dehydrogenase 1 (ALDH1) was sued to stain the cytoplasm of colorectal CSCs and DAPI was used to stain the nuclei of all tumor cells. Through observing the effect of different concentrations of As2O3 on CRC cells and colorectal CSCs, it was demonstrated that a sufficient concentration of As2O3 clearly inhibited the conversion from colorectal CSCs to CRC cells and increased the density of CSCs.
ABSTRACT
OBJECTIVE: To evaluate the clinical efficacy and safety of Qilin Pills in the treatment of oligoasthenospermia in infertile men. METHODS: This multi-centered randomized double-blind controlled clinical trial included 216 infertile males with oligoasthenospermia, 108 in the trial group and the other 108 in the control, the former treated with Qilin Pills at the dose of 6 g tid while the latter with Wuziyanzong Pills at 6 g bid, both for 12 weeks. We examined the total sperm count, sperm motility and the count of progressively motile sperm of the patients before and at 4, 8 and 12 weeks after medication and evaluated the safety of the drug based on the adverse events and the laboratory results of blood and urine routine examinations and liver and kidney function tests. RESULTS: Compared with the baseline, the patients in the trial group showed a significant time-dependent improvement after 4, 8 and 12 weeks of medication in sperm motility (21.75% vs 27.54%, 29.04% and 32.95%, P <0.05), total sperm count (156.27 ×106 vs 177.33, 188.18 and 205.44 ×106, P <0.05), and the count of progressively motile sperm (32.08 ×106/ml vs 46.33, 50.98 and 61.10 ×106/ml, P <0.05). The three parameters above were also improved in the controls, but more significantly in the trial group (P <0.05). CONCLUSIONS: Qilin Pills can evidently improve the semen quality of oligoasthenospermia patients with no obvious adverse events.

OBJECTIVE: To investigate the correlation between the syndrome types of traditional Chinese medicine (TCM) and clinical symptoms of benign prostatic hyperplasia (BPH) with chronic prostatitis (BPH-CP). METHODS: We selected 150 cases of BPH-CP in this study and divided them into 7 TCM syndrome types. Using univariate and multivariate logistic regression analyses, we studied the correlation of each TCM syndrome type with the age, disease course, prostate volume, postvoid residual urine volume (PVR), prostate-specific antigen (PSA) level, maximum urinary flow rate (Qmax), and International Prostate Symptoms Score (IPSS). RESULTS: Kidney-yin deficiency was correlated positively with the prostate volume but negatively with Qmax and IPSS; kidney-yang deficiency positively with the age and prostate volume but negatively with IPSS; the damp heat syndrome positively with the PSA level but negatively with the disease course, prostate volume and Qmax; the spleen-qi deficiency syndrome positively with the prostate volume but negatively with the disease course; liver-qi stagnation positively with the disease course but negatively with the age, prostate volume and PVR; the syndrome of qi stagnation and blood stasis positively with the disease course and IPSS but negatively with PVR; the syndrome of lung-heat and qi blockage positively with the age, Qmax and IPSS but negatively with the disease course. CONCLUSIONS: The TCM syndrome types of BPH-CP are closely correlated to their clinical symptoms. The analysis of the clinical objective indexes of BPH-CP can provide some reliable evidence for accurate identification of the TCM syndrome type of the disease.

Objective: To investigate the clinical effect of Jujing No.2 Decoction on male infertility induced by varicocele. METHODS: We equally randomized 70 male patients with varicocele-induced infertility into a treatment group and a control group, the former treated with modified Jujing No.2 Decoction (1 dose a day, bid) and the latter given Danshen Tablets (4 tablets once, tid) plus Liu Wei Di Huang Wan (8 pills once, tid), both for 3 months. We examined the spermatic veins of the patients by ultrasonography and performed seminal analysis before and after medication. RESULTS: Compared with the controls, the patients in the treatment group showed significant improvement after medication in sperm concentration (ï¼»12.35±2.12ï¼½ vs ï¼»18.56±4.16ï¼½ ×106/ml, P<0.05), progressively motile sperm (ï¼»16.18±6.34ï¼½ vs ï¼»24.63±8.51ï¼½ %, P<0.05), and morphologically normal sperm (ï¼»11.59±5.31ï¼½ vs ï¼»14.17±6.02ï¼½ %, P<0.05). In the control group, sperm concentration was increased from (12.29±2.07) ×106/ml at the baseline to (13.13±3.13) ×106/ml after medication, progressively motile sperm from (16.13±6.45) % to (20.55±7.30) % (P<0.05), and morphologically normal sperm from (11.62±5.35) % to (12.69±5.77) %. The total effectiveness rate was significantly higher in the treatment than in the control group (71.88% vs 46.67%, P<0.05). The inner diameter of the left spermatic vein was decreased from (0.32±0.05) mm at the baseline to ï¼»0.26±0.05ï¼½ mm after medication in the treatment group (P<0.05) and from (0.32±0.03) mm to (0.29±0.04) mm in the control (P<0.05), with statistically significant difference between the two groups after medication (P<0.05). CONCLUSIONS: Jujing No.2 Decoction is effective in the treatment of varicocele-induced male infertility.

OBJECTIVE: To explore the distribution, combination and evolution of various syndromic etiologies of erectile dysfunction (ED) based on the syndrome etiology theory. METHODS: Using the ED Syndromic Etiology Scale, we collected the clinical data on the Chinese medicine diagnoses of 297 cases of ED, extracted the core syndromic etiologies by analysis of principal components and factors, and analyzed the patterns of distribution, combination, and evolution of ED syndromic etiologies according to the general information of the patients. RESULTS: Through analysis of principal components and factors, 9 core syndromic etiologies were extracted, i. e. , liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, blood stasis, kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, and phlegm-damp. Each of these syndrome etiologies exhibited its own specific distribution patterns. Of the total number of cases studied, 51.52% had 2 or 3 core syndromic etiologies and 36.03% had only one. CONCLUSION: In the early stage of ED, its syndromic etiologies are usually liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, and blood stasis. With the natural progres- sion of the disease, its syndromic etiologies gradually evolve into kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, phlegm-damp, and blood stasis, and finally into yin-yang deficiency of the heart, spleen and kidneys, combined with phlegm-damp and blood stasis.

OBJECTIVE: To assess the efficacy of Yiqi Zhujing Particle in the treatment of idiopathic oligoasthenozoospermia. METHODS: We equally randomized 78 patients with idiopathic oligoasthenozoospermia to a control group and a Yiqi Zhujing group, the former treated with oral medication of zinc gluconate liquid (10 ml, bid) and vitamin E (100 mg, bid), and the latter given Yiqi Zhujing Granule (1 packet, bid) in addition, both for 3 months. We compared the semen parameters and biochemical indexes of the seminal plasma obtained before and after medication between the two groups of patients. RESULTS: After 3 months of treatment, remarkable improvement was observed in the percentage of progressively motile sperm and sperm viability in the control group (P < 0.05) as well as in the total sperm count, sperm concentration, percentage of progressively motile sperm, and sperm viability in the Yiqi Zhujing group (P < 0.05). The total sperm count, sperm concentration, percentage of progressively motile sperm, and sperm viability were even more significantly improved in the Yiqi Zhujing than in the control group (P < 0.05). Besides, both groups showed different degrees of improvement in the biochemical indexes of the seminal plasma, and the Yiqi Zhujing group exhibited even more significant improvement in seminal plasma zinc, alpha-glucoside enzyme, seminal plasma fructose, and acid phosphatase than the control (P < 0.05). The improvement of sperm concentration was correlated positively with the change of seminal plasma zinc (r = 0.201, P < 0.05) but negatively with that of seminal plasma fructose after treatment (r = -0.136, P < 0.05). There was a positive correlation between the alpha-glucoside enzyme level and sperm viability (r = 0.314, P < 0.05). CONCLUSION: Yiqi Zhujing Particle is effective for idiopathic oligoasthenozoospermia by significantly improving the total sperm count, sperm concentration, percentage of progressively motile sperm, sperm viability, seminal plasma zinc, seminal plasma fructose, and alpha-glucoside enzyme.

In obesity and diabetes, the ability of hypothalamic neurons to sense and transduce changes in leptin and insulin levels is compromised. The effects of both hormones require intracellular signalling via the PI3-kinase pathway, which is inhibited by the phosphatase PTEN. We show that leptin-stimulated F-actin depolymerization in mouse hypothalamic cells is inhibited by PTEN, a process involving independent effects of both its lipid and protein phosphatase activities. Potentially mediating this F-actin depolymerization, leptin, but not insulin, stimulated the phosphorylation of PTEN in a CK2 dependent manner, and inhibited its phosphatase activity. Similarly, hyperpolarization of mouse pancreatic beta-cells by leptin also requires coincident PtdIns(3,4,5)P3 generation and actin depolymerization, and could be inhibited by mechanisms requiring both the lipid and protein phosphatase activities of PTEN. These results demonstrate a critical role for PTEN in leptin signalling and indicate a mechanism by which leptin and insulin can produce PI3K dependent differential cellular outputs.

OBJECTIVE: To investigate the effects of San Baoxin on myocardial injury induced by ischemia-reperfusion (MI/R) and thrombogenesis in rats in vivo and ex vivo. METHOD: The experimental model was established by ligation of left anterior descending coronary artery for 30 min followed by reperfusion for 180 min. The Chandler method was used to produced ex vivo thrombosis and an electrical stimulation of common carotid artery was adopted to form in vivo thrombosis respectively, the effect of antithrombosis induced by San Baoxin was observed. RESULT: San Baoxin significantly decreased the content of malondialdehyde (MDA), obviously elevated the activity of superoxide dismutase (SOD) and increased the amount of NO of the serum simultaneously. The San Baoxin at the dosage of 10 g x kg(-1) could remarkably lengthen the OT ( P < 0.05). All San Baoxin dosages could inhibit the formation of ex vivo thrombosis. CONCLUSION: San Baoxin protects the myocardium from injury of ischemic and reperfusion. The protective effect of San Baoxin may be due to that it can dilate vessels, increase the activity of clearance enzyme of free radical and inhibit lipid peroxidation and the formation of ex vivo and in vivo thrombosis.

AIM: To investigate the therapeutic effects of Guiyuanfang and bone marrow stem cells (BMSCs) on rats with liver fibrosis. METHODS: Liver fibrosis model was induced by carbon tetrachloride, ethanol, high lipid and assessed biochemically and histologically. Liver function and hydroxyproline contents of liver tissue were determined. Serum hyaluronic acid (HA) level and procollagen III level were performed by radioimmunoassay. The VG staining was used to evaluate the collagen deposit in the liver. Immunohistochemical SABC methods were used to detect transplanted BMSCs and expression of urokinase plasminogen activator (uPA). RESULTS: Serum transaminase level and liver fibrosis in rats were markedly reduced by Guiyuanfang and BMSCs. HA level and procollagen III level were also reduced obviously, compared to model rats (HA: 47.18+/-10.97 ng/mL, 48.96+/-14.79 ng/mL; PCIII: 22.48+/-5.46 ng/mL, 26.90+/-3.35 ng/mL; P<0.05). Hydroxyproline contents of liver tissue in both BMSCs group and Guiyuanfang group were far lower than that of model group (1 227.2+/-43.1 microg/g liver tissue, 1390.8+/-156.3 microg/g liver tissue; P<0.01). After treatment fibrosis scores were also reduced. Both Guiyuanfang and BMSCs could increase the expression of uPA. The transplanted BMSCs could engraft, survive, and proliferate in the liver. CONCLUSION: Guiyuanfang protects against liver fibrosis. Transplanted BMSCs may engraft, survive, and proliferate in the fibrosis livers indefinitely. Guiyuanfang may synergize with BMSCs to improve recovery from liver fibrosis.
