ABSTRACT
The signaling pathways involved in acupuncture intervention in post-stroke depression (PSD) mainly include cAMP signaling pathway, MAPK signaling pathway, PI3K/Akt/mTOR signaling pathway, NF-κB signaling pathway, CREB signaling pathway, and CaMK signaling pathway. A variety of regulatory networks are formed between these signaling pathways, which play a key role in reducing inflammation, inhibiting apoptosis, improving neuroplasticity, promoting angiogenesis, and protecting neurons.
ABSTRACT
Acupuncture has a certain effect for the patients with post-stroke depression. In clinics, acupuncture treat this disease from the brain, liver and kidney, heart and spleen, and phlegm and blood stasis. Acupuncture plays a role in nourishing the bone of marrow, regulating the liver and kidney, nourishing the heart and mind, and invigorating the spleen and stomach. Acupuncture plays an antidepressant role by regulating neurotransmitters and receptors, promoting nerve function repair, inhibiting the secretion of inflammatory factors, reducing inflammatory response, inhibiting the hyperfunction of hypothalamic-pituitary-adrenal axis, and regulating the brain-gut axis.

<p><b>OBJECTIVE</b>To study the mechanism underlying the effect of the SOCS3 rs4969170 A/G alleles on the occurrence of insulin resistance (IR) in patients with chronic hepatitis C.</p><p><b>METHODS</b>The promoter region of the SOCS3 gene was amplified by PCR,and luciferase expression vectors were constructed and transfected into HepG2,Huh7 cell lines.The relative luciferase activity of each expression vector was assessed by the dual luciferase reporter gene assay system.Western blotting was used to detect SOCS3 protein expression in PBMCs from groups of patients with the rs4969170 AA and AG genotypes.The state of IR in eight patients was evaluated by determining their HOMA-IR.</p><p><b>RESULTS</b>The pGL3-A, PGL3-G and pGL3-control vectors showed significantly different luciferase expression in the HepG2 cells (0.121 00 ± 0.022 07,0.027 00+/-0.012 49 and 0.043 33 ± 0.005 51; F =48.068, P=0.001) and in the Huh7 cell lines (0.164 70 ± 0.007 10,0.027 33 ± 0.017 04 and 0.033 67 ± 0.014 98; F =115.137, P=0.001). The expression of SOCS3 protein was significantly higher in the rs4969170 AA genotype group than in the AG genotype group (1.22 ± 0.40 vs. 0.30 ± 0.19; t =4.149, P=0.006).The IR index of patients with the rs4969170 AA genotype and the AG genotype was 4.11 ± 2.62 and 1.47 ± 1.01 respectively.There were three patients with IR in the rs4969170 AA genotype group and one in the rs4969170 AG group. There was no statistically significant difference between the two genotype groups (t=1.881, P=0.109).</p><p><b>CONCLUSIONS</b>The SOCS3 rs4969170 A haplotype may enhance transcriptional activity of the gene promoter to regulate gene expression, thereby increasing intracellular SOCS3 protein level and ultimately interfering with insulin signaling and causing IR in patients with chronic hepatitis C.</p>

<p><b>OBJECTIV</b>To investigate the potential value of urine hepatitis B virus (HBV) DNA as a new noninvasive diagnostic indicator for HBV-associated glomerulonephritis (HBV-GN).</p><p><b>METHODS</b>A total of 152 patients including 66 with HBV-GN, 66 with non-HBV-GN, and 20 with chronic hepatitis B (CHB) without renal disease were examined for serum and urine HBV DNA levels using polymerase chain reaction (PCR) and for 5 serum HBV markers using enzyme-linked immunosorbent assays.</p><p><b>RESULTS</b>Twenty-two patients (33%) in the HBV-GN group, but none in the other two groups, were found positive for urine HBV DNA. In the diagnosis of HBV-GN, urine HBV DNA had a high specificity (0.98), a good positive predictive value (PPV, 0.96), and a modest negative predictive value (NPV, 0.60). Urine HBV DNA, alone or in combination with serum HBeAg, was superior in the diagnosis of HBV-GN to the combination of urine HBV DNA with serum HBV DNA, hepatitis B surface antigen and the hepatitis B e antigen.</p><p><b>CONCLUSION</b>Urine HBV DNA may be one of the new noninvasive diagnostic criterion for HBV-GN.</p>

ABSTRACT
Caenorhabditis elegans hid-1 gene was first identified in a screen for mutants with a high-temperature-induced dauer formation (Hid) phenotype. Despite the fact that the hid-1 gene encodes a novel protein (HID-1) which is highly conserved from Caenorhabditis elegans to mammals, the domain structure, subcellular localization, and exact function of HID-1 remain unknown. Previous studies and various bioinformatic softwares predicted that HID-1 contained many transmembrane domains but no known functional domain. In this study, we revealed that mammalian HID-1 localized to the medial- and trans- Golgi apparatus as well as the cytosol, and the localization was sensitive to brefeldin A treatment. Next, we demonstrated that HID-1 was a peripheral membrane protein and dynamically shuttled between the Golgi apparatus and the cytosol. Finally, we verified that a conserved N-terminal myristoylation site was required for HID-1 binding to the Golgi apparatus. We propose that HID-1 is probably involved in the intracellular trafficking within the Golgi region.

OBJECTIVE@#To evaluate the role of human calcium-activated chloride channel 1 (hCLCA1) and mucin MUC5AC in allergic rhinitis.@*METHOD@#The expression of hCLCA1 and MUC5AC were determined by RT-PCR and immunohistochemical assay in nasal mucosa on 20 patients with allergic rhinitis and 7 normal persons.@*RESULT@#The expression of hCLCA1mRNA in allergic rhinitis group was positive, whereas in normal control group was absent (P<0.01). The expression of MUC5AC mRNA and MUC5AC protein in the allergic rhinitis group were higher than that in the control, respectively (both P<0.01). The increased expression of hCLCA1mRNA in allergic rhinitis group were well correlated with the expression of MUC5ACmRNA and MUC5AC protein and the correlation coefficients were 0.752 and 0.694(both P<0.05).@*CONCLUSION@#Upregulation of hCLCA1 mRNA expression may play a pivotal role in mucus overproduction in allergic rhinitis group. The inhibition of HCLCA1 expression may provide a new strategy for the treatment of allergic rhinitis.

ABSTRACT
Objective L-selectin is an important adhesion molecule,which is the lymph cell's homing receptor specifically expressed on leukocytes.A non-lymphoma cell line-HCa-F has the high potential ability of metastasis to peripheral lymph nodes,whose character is similar to lymphoma's.We want to explore whether the HCa-F cell's metastasis mechanism is also similar to lymphoma's,that is to say,whether HCa-F cell can also express L-selectin and the expression of L-selectin bring about the lymph node metastasis character. Methods First,?-fetoprotein,CD3 and CD20's monoclonal antibodies were used to identify the origin of HCa-F cell;then we analysed whether the HCa-F cell can express L-selectin by means of flow cytometry analysis,RT-PCR,and Western blotting;finally,Stamper-Woodruff method was used to examine the L-selectin's function. Results Immunostaining showed that the HCa-F cell was ?-fetoprotein positive,CD3 and CD20 negative cell line,which suggests that it is a liver cell line.And results of flow cytometry,RT-PCR,and Western blotting showd that HCa-F cell can express L-selectin.Additionally,anti-L-selectin's antibody can inhibit the adhesion between HCa-F cells and frozen section of mouse lymph node.Conclusion L-selectin expressed on HCa-F cells is a functional molecule which can facilitate HCa-F cell's metastasis to lymph nodes.
