- Abstract：Liver fibrosis and hepatocellular carcinoma (HCC) are emerging health problems worldwide. Number of death due to HCC was steadily increased during the last decade. Although liver fibrosis and HCC have been investigated extensively, there are no successful and/or satisfactory therapies especially for patients with HCC. From our understanding of both Western medicine and Chinese medicine, it could identify the targets in liver fibrosis and HCC for intervention with Chinese medicine such as bone morphogenetic protein 4 (BMP-4). BMP-4 expression was significantly increased in both liver fibrosis and HCC and saponin class of certain Chinese herbs could regulate its expression. Therefore, BMP-4 could be one of the targets for treatment of liver fibrosis and HCC from integrative medicine.Keywords：Liver Fibrosis;hepatocellular carcinoma;bone morphogenetic protein;Integrative Medicine

Published：2021-08-27 - Abstract：Chronic kidney disease (CKD) and chronic liver disease are both very harmful to human health almost all over the world, which lead to the fibrosis of the two organs ultimately. Currently, there are few satisfactory therapeutic methods in treating the two diseases. Some research works from Chinese medicine and Western medicine were done in the area recently, the results showed that kidney and liver fibrosis shared similar biological signals and events such as epithelial-mesenchymal transition (EMT) and transforming growth factor β 1, the same herbal mesenchymal medicine exhibited significantly improving effects on both liver fibrosis and kidney fibrosis by involving similar mechanism. This coincides with the theory of homogeny of Liver (Gan) and Kidney (Shen) of Chinese medicine. It would provides new clues in exploring the treatment of liver fibrosis and kidney fibrosis.Keywords：homogeny;liver;kidney;fibrosis;saikosaponin-d

Published：2021-08-27 - Abstract：Contemporary Western medicines approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis B (CHB), although available in China, have high costs, or major side effects and limited effectiveness. Research efforts have focused on looking for natural products as alternative medicines with low cost and good safety for CHB treatment. Chinese medicine (CM) has ancient, time-honored theories about methods of diagnosis and treatment for liver diseases. In recent decades, a large number of clinical trials and pre-clinical studies, which were performed in China and other countries, indicated that CM has potential benefit in several aspects of the treatment of CHB, e.g., anti-inflammatory, anticancer, antioxidant, immunomodulating, antifibrosis, and antiviral. However, there are many concerns regarding the study design and the quality of clinical trials. Further larger, stringently designed, double-blind, placebo control, randomized clinical trials and long-term follow-up are needed to provide conclusive evidence of their efficacy and safety. Components of CM deserve further study in pre-clinical models of HBV infection and in clinical trials world-wide.Keywords：chronic hepatitis B;natural products;Chinese Medicine;Western Medicine;clinical trial

Published：2021-08-27 - Abstract：To investigate the effects of Qingre Huoxue Decoction 清热活血方, clearing heat and promoting blood flow; QRHXD), on the radiographic progression in patients with rheumatoid arthritis (RA) by X-ray imaging. Eighty-six patients with active RA diagnosed as damp-heat and blood stasis syndrome were randomized into a QRHXD group and a QRHXD plus methotrexate (MTX) group, with 43 cases in each group. After one-year of treatment, 21 cases in each group (42 in total) were evaluated. Radiographs of hands were obtained at the baseline and after 12 months of treatment. Images were evaluated by investigators blinded to chronology and clinical data, and assessed according to the Sharp/Van der Heijde methods. High intrareader agreements were reached (mean intraobserver intraclass coefficients: 0.95). No significant change in any imaging parameters of joint destruction was observed at 12 months in either group; and the differences between the two groups were not significant (P>0.05). The mean of the changing score in the QRHXD group was 3.5±4.1, and 2.4±3.5 in the QRHXD+MTX group, while the baseline radiographic score of patients in the QRHXD group was relatively higher (18.9±19.1 vs. 14.0±14.0). The mean rates of the changing scores of the two groups were similar (0.24±0.28 vs. 0.25±0.44, P=0.40). The severity of progression in the two groups was also similar (P=0.46), 7 cases without radiographic progression in the QRHXD group and 8 in the QRHXD+MTX group, 3 cases with obvious radiographic progression in the QRHXD group and 1 in the QRHXD+MTX group. Radiographic progression of RA patients in both groups is similar, indicating that the QRHXD Decoction has a potential role in preventing bone destruction.Keywords：rheumatoid arthritis;Qingre Huoxue Decoction;Chinese Medicine;herb;radiology;bone destruction

Published：2021-08-27 - Abstract：To investigate the therapeutic effects of Ping-tang Recipe (平糖方, PTR) on high-fat diet (HFD)-induced insulin resistance and non-alcoholic fatty liver disease (NAFLD), and to elucidate the underlying mechanisms. Forty male SD rats were included in the study. Ten rats were fed on normal diet as normal control, and thirty rats were fed on HFD for 8 weeks to induce obesity, followed with low dose (0.42 g/kg) or high dose (0.84 g/kg) of PTR or vehicle for 8 weeks with 10 animals for each group. Glucose metabolism and insulin sensitivity were evaluated by oral glucose tolerance test and insulin tolerance test. Hepatic steatosis was measured by immunohistochemistry. Liver lipid metabolic genes were analyzed by quantitative real-time polymerase chain reaction, while AMP-activated protein kinase (AMPK) expression was examined by Western blot. Rats fed on HFD developed abdominal obesity, insulin resistance and NAFLD. PTR treatment reduced visceral fat (peri-epididymal and peri-renal) accumulation, improved glucose metabolism, and attenuated hepatic steatosis. The expressions of the key lipolytic regulating genes, including peroxisome proliferators-activated receptor γ co-activator 1α (PGC-1α), peroxisome proliferator-activated receptor γ (PRAR-γ) and α (PRAR-α), were up-regulated (P<0.05 or P<0.01), while the expressions of lipogenic genes such as sterol regulatory element-binding protein 1c (SREBP-1c), fatty acid synthase (FAS) and liver fatty acid-binding protein (L-FABP) were down-regulated (P<0.05 or P<0.01). In addition, PTR activated AMPK and promoted acetyl-CoA carboxylase phosphorylation in the liver. PTR improves insulin resistance and reverse hepatic steatosis in the rat model of HFD-induced obesity through promotion of lipolysis and reduction of lipogenesis, which involves the AMPK signaling pathway, thus representing a new therapeutic intervention for obesity related insulin resistance and NAFLD.Keywords：Ping-tang Recipe;non-alcoholic fatty liver disease;insulin resistance;AMP-activated protein kinase

Published：2021-08-27 - Abstract：To observe the regulation of Youguiyin (YGY, 右归饮) on the gene expression profile of the rat with steroid-induced femoral head necrosis (sFHN), for the sake of investigating its molecular mechanism of sFHN prevention and treatment. All the 30 rats were randomly divided into three groups, the normal control group (A), the model control group (B), and the YGY treated group (C), 10 in each group. After rats in Groups B and C were being made into FHN models with steroid injection, they received a daily intragastric administration of saline and YGY respectively in equal volume for a total of 6 weeks, while to the unmodeled normal rats in Group A, saline was administered instead. The rats were sacrificed at the terminal of administration; their mRNA from femoral head tissue was extracted and prepared to cDNA probe through inverse transcription for detecting gene expression profile by microarray, outcomes of which was passing fluorescence quantitative PCR verification, and the differential expressed genes were analyzed adopting gene ontology (GO) method. Compared with Group A, the numbers of differential genes found in Groups B and C were 190 and 92, respectively, but the changing trend in the two groups was opposite, mainly manifested as down-regulating in Group B/Group A (GB/GA) and up-regulating in Group C/Group B (GC/GB). The analysis showed that these differential genes were mainly assigned to cell apoptosis, signal transduction, metabolism, cell proliferation and differentiation, cell cycle, blood coagulation, antioxidant activity, etc. sFHN was regulated by various genes; the regulation of YGY on expressions of these genes and the intra/extra-cellular signaling processes was possibly the molecular mechanism of YGY for preventing/treating sFHN. This study gave an explanation to the effectiveness of Chinese medicine in preventing/treating FHN from aspects of gene expression and enriched the Chinese medicine theory of “Kidney (Shen) governing bones”.Keywords：Youguiyin;steroid-induced femoral head necrosis;gene chip;gene expression profile;molecular mechanism

Published：2021-08-27 - Abstract：To assess the effect of puerarin, a natural flavonoid found in Chinese Pueraria Lobata (Wild.) Ohwi, on promotion of new bone formation. Osteoblasts isolated from calvarial of newborn rats were cultured in vitro in the presence of puerarin at various concentrations. The viability of osteoblasts and alkaline phosphotase activity and mineral node formation were determined. In addition, osteoblasts seeded in the β-tricaclium phosphate scalfolds as bone substitute were implanted in rat dorsal muscles. Half -of the recipient rats received intramuscular injection of puerarin at 10 mg/(kg·d) for 7 days. Osteogenesis was analyzed by examining the histology after 4 weeks of implantation. The viability of osteoblasts treated with puerarin at either 40 or 80 μmol/L was significantly higher than that of the control (P<0.05 and P<0.01, respectively). Alkaline phosphatase and mineral modules were significantly increased in osteoblasts cultured with puerarin at 40 or 80 mol/L when compared with that of the untreated cells. The puerarin-treated rats had a higher rate of bone formation in the osteoblast implants than the control rats (6.35% vs. 1.32%, respectively, P<0.05). Puerarin was able to affect osteoblast proliferation and differentiation, and promote the new bone formation in osteoblast implants.Keywords：Puerarin;osteoblast;β-tricalcium phosphate;new bone formation

Published：2021-08-27 - Abstract：To investigate the effect of puerarin on interleukin (IL)-8 mRNA expression and the protein release in the co-culture of human bronchial epithelial (BEAS-2B) cells and human neutrophils. BEAS-2B cells and neutrophills were cultured separately and co-cultured with puerarin (50, 100, and 200 μg/mL) for a predetermined time. Cytokines in culture supernatant were evaluated by protein array and IL-8 quantified by enzyme-linked immunosorbent assay (ELISA). IL-8 mRNA expression was evaluated by real-time quantitative polymerase chain reaction (real-time qPCR). The co-culture of BEAS-2B cells and neutrophils exhibited synergistic effects on IL-8 mRNA expression in BEAS-2B cells, but not in neutrophils after 12 h incubation (P<0.01), as compared with that in BEAS-2B cells or neutrophils alone. IL-8 protein release in the culture supernatant was obviously elevated when BEAS-2B cells were co-cultured with human neutrophils as compared with that in the supernatant of BEAS-2B cells or neutrophils alone after incubated for 2, 6, 12, and 18 h (P<0.01). Treatment with puerarin could significantly down-regulate the expression of IL-8 mRNA in BEAS-2B cells and IL-8 release in the supernatant of the co-culture of BEAS-2B cells and neutrophils (P<0.01). Puerarin could exhibit anti-inflammatory activity by suppressing IL-8 production from the co-culture of human bronchial epithelial cells and neutrophils.Keywords：bronchial epithelial cells;interleukin-8;neutrophils;Puerarin

Published：2021-08-27 - Abstract：To compare the regulatory effects of electro-acupuncture (EA) at acupoints Zusanli (ST36) and Hegu (LI4) on the visceral hyper-sensitivity in the rat model of irritable bowel syndrome (IBS), and to explore the acting targets and specialty of acupoints. Except 8 rats of the normal control group, the rest 32 rats were prepared to set up the IBS models. IBS animal model was prepared by enema with acetic acid. Model rats were divided into three groups. Except for rats in the model group for control, those in the other two groups were treated 20 min by EA on ST36 (EA-ST36) and LI4 (EA-LI4) respectively for 2 weeks to observe the effect on behavior response of viscera sensitivity. The changes of neuropeptide (NPY), the somatostatin (SS) levels in blood and tissues of brain and intestine were monitored as well. The volume thresholds for abdomen uplifting and back hunching were obviously increased after EA-ST36 (P<0.05), but showed insignificant change after EA-LI4. NPY contents lowered and SS contents increased in model rats; both EA-ST36 and EA-LI4 could raise the level of thalamic NPY (P<0.01 and P<0.05, respectively), but showed insignificant effects on NPY in colonic tissue. As for SS content, its colonic level could be reduced by EA-S36 and EA-LI4 (P<0.01 and P<0.05, respectively), however, its blood level was affected only by EA-ST36 (P<0.05). EA-ST36 or EA-LI4 could regulate the NPY in thalamus and SS in colonic tissue, the former could affect blood level of SS as well. It is deemed that NPY and SS may be the key substances for regulating the action of acupuncture in the brain-intestinal axis; their different levels could be regarded as an indicator for the functional difference between the acupoints.Keywords：electro-acupuncture;rat’s model of irritable bowel syndrome;brain entero-peptide;neuropeptide Y;somatostatin

Published：2021-08-27 - Abstract：To explore the molecular mechanism of puerarin (Pue) in improving insulin resistance through observing its effect on the insulin resistance of 3T3-Li lipocyte induced by free fatty acid (FFA). 3T3-L1 preadipocyte was induced by a culture solution containing insulin, isobutyo-menthyl-xanthine, and dexamethasone to mature lipocyte, and it was divided into six groups: the control group (normal cells), the model group (untreated model cells), and the four drug treatment group exposed to dimethyl biguanide (Met group), highdose puerarin (PueH group), low-dose puerarin (PueL group), and propylene glycol (PG group), respectively. Mature lipocytes in various groups, except those in the normal group, were established into insulin resistance model by FFA induction and treated respectively with corresponding drugs. Peroxisome proliferator-activated receptor-γ (PPAR-γ) mRNA expressions at the fourth, sixth, and eighth day were observed using reverse transcription polymerase chain reaction (RT-PCR); glucose transportation in various groups were observed by 2-deoxy-[3H]-D-glucose intake method; mRNA expression of Cb1 binding protein (CAP) was determined by RT-PCR; and glucose transporter-4 (Glut-4) transposition was detected by immune-fluorescence method. PPAR-γmRNA expression increased gradually, and it showed lower levels at the fourth, sixth, and eighth day in all treatment groups than that in the model group. Glucose transportation determination showed that the transportation in the model group was 2.23±0.63, significantly lower than that in the normal group 5.05±0.66 (P<0.01); as compared with the model group, they were significantly higher in the PueH and the PueL groups. In addition, the CAP mRNA expression and membranous distribution of Glut-4 were higher in the two Pue treated groups than those in the model group, respectively. Pue could markedly improve the insulin resistance of 3T3-L1 lipocyte, which is realized possibly by way of inactivating CAP path, promoting Glut-4 transposition to cell membrane to increase the transportation of glucose.Keywords：Puerarin;insulin resistance;peroxisome vegetation activating receptor-γ;Cb1 binding protein;glucose transporter-4

Published：2021-08-27 - Abstract：To study the effect of Vaccinium uliginosum L., (VU) on the electroretinogram (ERG) and retinal pathological changes in rabbits after light-induced damage. Twenty-eight Chinchilla rabbits were randomly divided into four groups: administration beforehand (A), administration after injury (B), light injury without administration (C), and blank (D) groups. After a 4-week administration of VU homogenate at 4.8 g/(kg·d) once a day in group A, ERG in groups A, B and C were recorded according to the standards set by the International Society for Clinical Electrophysiology of Vision (ISCEV). Except for group D, the groups were then exposed to strong light. Just after that, group A stopped receiving VU treatment and group B started to receive it. Then ERGs in all groups were recorded after 1 day, 1 week, and 2 weeks. Throughout the whole process groups which were not fed with VU were fed with normal saline. Finally, the tissues and structures of all the groups were observed and the thickness of the outer nuclear layers (ONL) was measured. (1) After 4-week feeding with VU, the latency time of ERG in group A became shorter than those in the other groups and the amplitude increased. After being exposed to strong light, the latency time lengthened and amplitude decreased in all the injury groups, but comparing at each time point, the measured values in group A were better than those in group C. With the accumulation of VU, the ERG in group B improved, and finally, all of the detected values became better than those in group C. (2) Retinae in group D were normal in histology and the layers were in order but those in group C became disarranged. The injuries in groups A and B were minor compared with those in group C. The thickness of the ONL in group C was significantly thinner than in the other groups (P=0.000), and that in groups A and B was thicker than that in group C, although thinner than in group D. That in group A was thicker than in group B. VU can relieve the injury to rabbit retinae exposed to normal day and night rhythm, alleviate the harm caused by light when used beforehand, and repair the light damage to the retina.Keywords：Vaccinium uliginosum L.;light-induced damage;electroretinogram;histology

Published：2021-08-27 - Abstract：To study and evaluate the effect of Sangu Decoction (SGD, 三骨汤) on the bone destruction due to mammary cancer metastasis. Metastasis rat mammary tumor-1 cells were transplanted into the left hind limb tibia of SD rats to establish the bone metastasis of the mammary cancer model. The modeled rats were treated with SGD for observing its effect on rats’ pain behavior, including 50% paw withdrawal threshold (50% PWT) after von Frey fiber stimulation, burden difference of bilateral feet, and thermal withdrawal latency (TWL), with zoledronic acid as the positive control. Moreover, the damage in the tibia sample of rats was scored by an iconographic method, and the bone mineral density (BMD) as well as the bone mineral content (BMC) were estimated. The model established showed characteristics of mixed metastasis, revealing the manifestations of tumor development, bone destruction, cancerous pain, etc. In the SGD-treated group, 50% PWT was prolonged (8.13±4.76 vs. 2.30±2.19), and TWL was longer (3.48±0.62 s vs. 2.89±0.26 s) than those in the control group, respectively (P<0.05 or P<0.01). Iconographic scoring also showed improvement of BMD (0.134±0.009 vs. 0.120±0.007, P<0.01) and an elevating trend of BMC in the SGD-treated group. SGD could effectively alleviate the cancerous pain of bone metastasis and mitigate the metastasis that cause osteolytic destruction of bone.Keywords：cancerous pain;metastasis of mammary cancer;Chinese medicine therapy;bone destruction

Published：2021-08-27 - Abstract：A Chinese medicine (CM) approach, designed based on the clinical experiences of the West Los Angeles Center for Traditional Chinese Medicine, is a practical path for assessing and treating breast cancer survivors. The approach consists of balancing the body with deciphering the cause of the patient’s chief complaints by assessing and recognizing the six physiological dysfunctions that include gastrointestinal problems, sleeps problems, emotional imbalance, low body energy, menstrual change and pain. Multifaceted interventions are used for eliminating various CM pathologies based on identifying the basic CM patterns (syndromes) differentiation. Watching to assess the above two situations dynamically is used for outcome evaluation and predicting prognosis. Therefore this approach is called BMW. It can serve as a reference for CM clinical practice and integrative clinical care. It also can be used to simplify the clinical interpretation of CM and provide an easier way for CM doctors to communicate with Western medical doctors and patients. Additionally, it can be used as a guide for patients to assess their own symptoms for self-monitoring and self-care.Keywords：breast cancer survivors;Chinese Medicine;follow-up care;cancer related fatigue
