Liver cancer has always been a threat to national health since liver disease has a high incidence rate in China. At present, methods for the prevention and treatment of liver cancer have unsatisfactory effects in clinical practice, and with in-depth studies, scholars have changed their focus to cancer-associated fibroblasts (CAFs) in tumor microenvironment. More and more evidence has shown that CAFs may provide a new target for the prevention and treatment of liver cancer. This article summarizes the role of CAFs in the development and progression of liver cancer and the potential of CAFs in the treatment of liver cancer.

Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.

OBJECTIVETo observe the intervention and mechanism of Qushi Huayu Recipe (QHR) on gene expression profiles in high lipid diet induced fatty liver rats.
METHODSFatty liver model was prepared in 20 male SD rats using single high fat diet (88% common forage +2% cholesterol +10% lard). Four weeks after modeling they were divided into the model group and the QHR group according to random digit table, 10 in each group. QHR (at 0. 93 g crude drug/100 g body weight) and distilled water was respectively to rats in the QHR group and the model group by gastrogavage while modeling, once per day. Meanwhile, 10 SD male rats were recruited in a normal group, administered with equal volume of distilled water by gastrogavage. At the end of week 8 all rats were sacrificed, and blood and livers were collected for subsequent analysis. Contents of liver triglyceride (TG) and free fatty acid (FFA) , activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using biochemical assay. Pathological changes of liver tissue were observed using H&E and oil red O stain. Liver gene expressions were detected by Affymetrix gene expression profiles. Differentially expressed genes were compared between the QHR group and the model group, functions of differentially expressed genes and signal pathways involved analyzed. Ten differentially expressed genes involved in glycolipid metabolism with fold change more than 2 were selected for verification by real-time PCR.
RESULTS(1) Compared with the normal group, contents of liver TG and FFA, and serum activities of ALT and AST obviously increased in the model group (P <0. 01). Compared with the model group, contents of liver TG and FFA, and activities of ALT and AST obviously decreased in the QHR group (P <0. 05, P <0. 01). QHR could reduce high fat induced fatty degeneration of liver cells , alleviate inflammation, and improve pathological changes of liver tissue. (2) Compared with the model group, there were 80 differentially expressed genes (with fold change > 2, P < 0.05) with clear functions and appointed gene names, including 44 up-regulated and 36 down-regulated genes. Eighty genes were involved in 27 signal pathways with statistical difference, including glycerolipid metabolism, adipocytokine signaling pathway, insulin signal pathway, drug metabolism signal pathway, etc (P < 0.05). (3) RT-PCR results of 10 glycolipids metabolism regulating genes such as Gk, Scd1, Gpat2, G6pc, Irs1, and so on showed that all RT-PCR genes were completely coincide with up-regulated or down-regulated tendency in results of gene chips. 80% genes had approximate fold change.
CONCLUSIONQHR could regulate gene expressions related to fat metabolism, carbohydrate metabolism, anti-lipid peroxidation, and drug metabolism in high fat diet induced fatty liver rats, and its comprehensive pharmacological actions could be manifested.

As a neuropeptide, neurotensin (NTS) is widely expressed in central and peripheral nervous system, which is mainly mediated byneurotensin receptor1 (NTSR1) to activate the related downstream signaling pathways. After summarized the function and mechanism of NTS/NTSR1 in various malignant tumors, we found that NTS/NTSR1 played essential roles during tumor initiation and development. NTS/NTSR1 regulates tumor initiation, proliferation, apoptosis, metastasis and differentiation mainly through three pathways, including IP3/Ca2+ /PKC/MAPKs pathway, MMPs/EGFR/MAPKs (PI3K/Akt) pathway, or Rho-GTPsaes and non-receptor tyrosine kinase pathway. Besides, NTS/NTSR1 is also regulated by some upstream pathways and some traditional Chinese medicine preparations and traditional Chinese medicine therapies. In this article, we summarized the function of NTS/NTSR1 and its mechanisms, and discussed the prospective in its application to clinical diagnosis and drugs targeting.

Objective To study the mechanism of marcosomia by investigating insulin-like growth factor 2(IGF_2)imprinting status,expression level and the promoter usage in the placenta of macrosomia. Methods We selected heterozygous cases for Apa Ⅰ polymorphism in exon 9 of IGF_2 gene and then analyzed its imprinting status in 168 placentas of macrosomia and normal pregnancies.IGF_2 transcription levels and promoter usages in macrosomic and normal placenta were evaluated by using semi-quantitative RT- PCR assay.Results Thirty specimens of macrosomic placenta and 30 of normal placenta were identified as heterozygous for IGF_2.All of the heterozygous specimens showed maintenance of imprinting.The expression of placental IGF_2 mRNA(2.2?1.2)was significantly higher in macrosomia than that of normal weight group (1.6?0.6,P 0.05).Conclusion It is possible that over expression of IGF_2 in placenta contributes to macrosomia while the promoter usage and imprinting status are not associated with macrosomia.
