PP: 2290-2295
Abstract: Objective: To observe the protection of Qishenyiqi (QSYQ) dripping pills and its influence mechanism on glycogen synthase kinase-3β (GSK-3β) pathway. Methods: 50 male SD (sprague dawley) rats were randomly divided into normal group, model control group, experimental model group, isosorbide dinitrate (ISD) group and QSYQ group, each group included 10 rats. The myocardial infarction model and the deficiency of Qi and blood stasis myocardial infarction model were established respectively. With ISD and QSYQ dripping pill intervention, cardiac ejection fraction (EF), myocardial infarction and protein and gene expression of GSK-3β, Toll like receptor 4 (TRL4), nuclear factor-κB (NF-κB), β-catenin in myocardial tissue were observed. Results: After nitroblue tetrazol ium (NBT) staining, myocardial tissue in the normal group was stained purple; Large gray infracted regions and smaller gray infarction areas in myocardial tissue were found in model groups and QSYQ group respectively. The EF in the model groups was significantly lower than that in the normal group; The cardiac function was significantly improved in ISD and QSYQ group (P<0.01). Immunohistochemical results showed that the number of cells with positive expression of GSK-3β and TRL4 proteins decreased in the normal group, which was lower than that in model group (P<0.01); ISD and QSYQ dripping pills could decrease the expression of GSK-3β and TRL4 protein (P<0.01). Real-time PCR (RT-PCR) results showed that the expression level of β-catenin gene was the highest while the expression level of NF-κB gene was the lowest in the normal group. The expression level of β-catenin gene in the model group was lower than that in normal group, while the xepression level of NF-κB gene in the model group was higher than that in normal group (P<0.01); Both ISD and QSYQ dripping pills could promote the expression of β-catenin gene, while inhibit the expression of NF-κB gene (P<0.01). Conclusion: QSYQ dripping pills could inhibit the death of myocardial cells through regulating TRL4/NF-κB, GSK-3β/β-catenin pathway, thus achieved the protection effect on myocardial.

Authors: LIN Dongyang, YANG Bohua, SHEN Ling
PP: 2285-2289
Abstract: Objective: To study the effects of Astragalus, vascular endothelial growth factor (VEGF) and stromal cell-derived factor 1 (SDF-1) on the human bone marrow mesenchymal stem cells (hBMSCs) capabilities of migrating to the lesion sites and differentiating into vascular endothelial cells (VECs) by simulating hypoxic environment of human body. Methods: Using Transwell system, the experimental cells were randomly divided into 7 groups. The three normxic groups were placed in ordinary cell culture incubator (including 21% O2); The four hypoxic groups were placed in the special cell culture incubator (including 5% O2). After 48-h culture, the cells were counted by randomly selecting three consecutive microscope visual fields below the membrane,and the final cell number was the average of three visions. Results: 1) Among the three normoxic groups,the ability of migration of hBMSCs in SDF+Astragalus+normoxic group was significantly higher than that of others (P<0.01,P<0.05); 2) Among the four hypoxic groups,the ability of migration of hBMSCs in SDF+Astragalus+hypoxic group was significantly higher than that of others (P<0.01);the ability of migration of hBMSCs in SDF+hypoxic group was significantly higher than that in hypoxic control group (P<0.01);the ability of migration of hBMSCs in hypoxic+Astragalus group and hypoxic control group had no significant difference (P>0.05); 3) The ability of migration of hBMSCs in SDF+Astragalus+hypoxic group was significantly higher than that in SDF+Astragalus+normoxic group (P<0.05); The ability of migration of hBMSCs in SDF+normoxic group and SDF+hypoxic group had no significant difference (P>0.05);The ability of migration of hBMSCs in Astragalus+normoxic group and Astragalus +hypoxic group also had no significant difference (P>0.05). Conclusion: In normoxic and hypoxic environments, Astragalus combined with SDF-1 could promote the migration of BMSCs. However, Astragalus alone could not promote the migration of BMSCs in the hypoxic environment.

PP: 2280-2284
Abstract: Objective: To study the correlation between tongue color and 7 parameters of red blood cells in peripheral blood. Methods: Tongue color of 2 218 cases of health check-ups (male: 888 cases, female: 1 330 cases) were observed. The tongue color was judged by doctors of traditional Chinese medicine. The indexes of red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and red blood cell volume distribution width (RDW) were detected by collecting venous blood samples. The comparisons of occurrence rates of different tongue colors were tested using the chi-square test. The correlations between tongue colors and the red blood cell parameters were analysized using t-test or rank sum test. Results: 1) The appearance rate of pale tongue, pink tongue and dull tongue was higher while dark red tongue was lower in females than those in males (P<0.01). RBC, HGB and HCT decreased while RDW increased in female pale tongue group when comparing with those in female pink tongue group (P<0.05, P<0.01); RBC, HGB and HCT increased in female red tongue group (P<0.05); 2) Compared with those in pink tongue group, RBC and HCT of the dark red and dark purple tongue’s increased (P<0.05, P<0.01) in both male and female. Conclusion: 1) The appearance rates of light colored tongue (including pale tongue, pink tongue and light dark tongue) in female were higher than those in male; 2) The shades of the tongue color was positive related to HGB and HCT; 3) The dark red and dark purple tongue had the closest relationship with the increase of HGB and HCT.

PP: 2273-2279
Abstract: Objective: To observe the effects of intra-articular injection of danshen and sodium hyaluronate (SH) on treatment of rat knee osteroarthritis (KOA). Methods: Thrity sparague-dawley (SD) rats were randomly divided into health group (A), osteoarthritis (OA) group (B) and experimental group (C). The rats of B group and C group (total 20 rats) were given intra-articular injection with the 20 μL mixture of 4% papain solution and 0.03 mol/L L-cysteine at the first day, second day and third day respectively, to establish the model of KOA. At the same time, the rats of C group were given intra-articular injection of 0.06 mL SH and 0.06 mL danshen once a week. The knee joint activity scopes of the rats were measured and then the rats were sacrificed at the fourth week after the first injections. The knee cartilages were cut for general observation and pathologically examination and the results were performed Mankin’s scores. Results: The knee joint activity scope of C group was significant larger than that of B group (P<0.01). Furthermore, the cartilage damage mitigated in C group, and the Mankin’s scores of C group improved and had significant difference when comparing with that of B group (P<0.05). Conclusion: The combination of danshen injection with SH injection could improve the knee joint activity scope, protect the cartilage structure, reduce the degree of cartilage degeneration, and alleviate the destruction of the cartilage cells and the pathology of KOA, but they could not inhibit the process of KOA completely.

Title: Study on PD1/PD-L1 expression in chronic hepatitis B patients
Authors: ZHANG Wenjin
PP: 2238-2242
Abstract: In this study, the chronic active hepatitis patients were taken as research objects. According to the infiltration number of transaminases and CD8+ lymphocytes in liver tissue, the inflammation period was divided into four phases. The results showed that the expression of PD-1/PD-L1 was up-regulated significantly in inflammation flare-up period. With the reduction of inflammation, the expression level of PD-1 and PD-L1 decreased. Furthermore, PD-1 and PD-L1 were co-expressed with their positive costimulatory partner. These results suggested that the up-regulation of negative costimulatory molecules were needed during inflammation period to maintain homeostasis by the balance of positive-costimulatory signals, rather than specifically inhibit hepatitis B virus (HBV)-specific immune response.

PP: 2231-2237
Abstract: The present study was undertaken to investigate the effect of brain tumour necrosis factor-α (TNF-α) and the cytokine synthesis inhibitor pentoxifylline (PTX) on the sympathetic nerve activity in diabete mellitus (DM) rats. Sprage-dawley (SD) rats were randomly divided into SHAM+VEH, SHAM+PTX, DM+VEH and DM+PTX groups. Rats were fed with high fat and sugar diet for 4 weeks following by injection of streptozotocin streptozotocin (STZ) to induce the diabetes mellitus. Rats were implanted with paraventricular nucleus (PVN) cannulae and treated with PTX, or vehicle (VEH) for 4 weeks. After 4-week treatment, the level of blood glucose and body weight were measured. Immunohistochemisty were used to detect the expression of TNF-α in the PVN of hypothalamus. The activity of renal sympathetic nerve activity (RSNA) was recorded using electrodes. The results were: 1) The expression of TNF-α in the PVN of DM group increased, and the level of TNF-α in DM+SHAM group was higher than that in DM+PTX groups; 2) RSNA significantly increased in DM group. Compared with SHAM groups, diabetic rats had augmented RSNA. Sympathetic nerve activity significantly decreased in diabetic rats by blocking synthesis of TNF-α in PVN. In conclusion, the results suggested that TNF-α in the PVN played an important role in sympathetic nerve activity of diabetic rats.

Authors: BAO Yun, WANG Wenjuan, LI Qiong, CHEN Qi, LIU Xiuping, XU Zude, TANG Feng
PP: 2226-2230
Abstract: Objective: To observe the effects of short-term chemotherapy on the expression of ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), epithelial growth factor receptor (EGFR) and P-glycoprotein (P-gp) in the breast carcinoma before surgery. Methods: The expressions of UCH-L1, EGFR and P-gp were assessed by immunohistochemistry (EnVision method) in 40 cases breast carcinoma before and after treatment by multidrug resistance (MDR) drugs. Results: The expression of UCH-L1 was decreased after chemotherapy with MDR drugs when comparing with that before chemotherapy (P<0.05), while the rate of positive EGFR expression increased significantly after chemotherapy (P<0.01). However, the expression of P-gp had no significant difference before and after chemotherapy (P>0.05). Negative associations were revealed between UCH-L1, EGFR and P-gp expression and volume reduce of tumor and lymph node metastasis. Conclusion: Short-term chemotherapy could kill tumor cells and influence the expression of UCH-L1, EGFR and P-gp. The mechanisms may be the selectivity damages of the MDR drugs on the tumor cells. However, the expression of CD147 and other downstream factors had no changes after chemotherapy with MDR drugs.

PP: 2221-2225
Abstract: Objective: To investigate the role of suppressor of cytokine signaling 1 (SOCS-1) on renal injury in diabetic mice. Methods: Male CD-1 mice were randomly divided into 4 groups: control group, diabetic group, empty plasmid vector transfection group and SOCS-1 plasmid transfection group. Mice were given an intraperitoneal injection of streptozotocin (STZ) to induce the model of diabetic mice. Then transfection mice were given an caudal vein injection of SOCS-1 plasmid or empty vector once 7 day. After 4 weeks of injection, specimens were collected to detect the blood glucose and 24 h urine protein. Western blotting analysis were used to determine the expression level of SOCS-1 protein. The expression level of macrophage marker protein CD68 in renal tissue was detected by flow cytometry. The levels of interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) in renal tissue were detected by ELISA. Results: Overexpression of SOCS-1 could inhibit the expression of cluster of differentiation 68 (CD68), IL-1β and TGF-β1 in renal tissue and ameliorate the excretion of urine protein of diabetic mice, but it had no effects on blood glucose level. Conclusion: Overexpression of SOCS-1 could relieve renal injury through reducing the inflammatory response in renal tissue of diabetic mice.
