Objective:To explore the influence of embryonic stem cells-derived neural stem cells on the proliferation and secretion cytokines of bone marrow-derived macrophages. Methods:Mouse bone marrow derived macrophages were isolated and cultured in L929 medium. After macrophages were treated with NSCs supernatant for 3 days,SRB method was used to detect the proliferation of macrophages. The phagocytosis of macrophages were detected by incubating with RFP-Beads for 1 h. Meanwhile,the expression of TNF-α and IL-1β were detected by ELISA. Results:NSCs were successfully induced from ESC. In control group and NSC group, the proliferation rate of macrophages were 100 % and (126. 29 ± 5. 41)%,the phagocytosis rate were (70. 23 ± 2. 57)% and (90. 32 ± 8. 49)%. Compared to the control group,the levels of IL-6,IL-1βin macrophage treated with NSCs decreased (P<0. 05). Conclusion:ESC-derived NSCs can promote the proliferation and phagocytosis of bone marrow-derived macrophage, and suppress the secretion of pro-inflammatory cytokines.

Objective: To investigate the effect of scalp point-through-point acupuncture on 200 kDa neurofilament protein (NF-200) in rats with acute cerebral infarction and explore its mechanism on nerve plasticity in cerebral infarction rats. Methods: Healthy male Wistar rats were randomly allocated to sham operation (Group A), model (Group B) and acupuncture (Group C) groups. A rat middle cerebral artery occlusion (MCAO) model of cerebral ischemia was made. NF-200 mRNA was measured by reverse transcriptase polymerase chain reaction (RT-PCR) in each group on the 7th, 14th and 28th days. Results: The cerebral expression of NF-200 in group C was significantly different from those in groups A and B (P＜0.05); there was a significant difference between groups C and B or A at different time windows (P＜0.01),indicating that scalp point-through-point acupuncture could improve the cerebral expression of NF-200. Conclusion: Scalp point-through-point acupuncture can improve neural function,promote the recovery of limb function and increase the expression of NF-200 after cerebral ischemia, exerting a regulative effect on neuronal plasticity in the brain.

Objective To study effect and its possible mechanism of total glucosides of paeony ( TGP ) on adriamycin-induced nephropathy rats.Methods Thirty male SD rats were randomly divided into normal group ( CON) , adriamycin-induced nephropathy group ( ADRN) and TGP-treated ADRN group (TGP).The rat nephropathy model was established by adriamycin injection.At the end of the 8th week after treatment, ELISA was used to detect the level of Cr and BUN.The values of 24 urine protein was determined by urinary protein kit.Masson staining was used to observe the fibrosis.RT-PCR was used to detect the mRNA levels of TLR4/NF-κB/TGF-β1 .Immunohistochemical method was used to detect the content of TLR4/NF-κB/TGF-β1.ResuIts Compared with the CON group, the level of Cr, BUN, 24 urine protein of ADRN group rised(P<0.01), the degree of fibrosis of ADRN group were aggravated(P<0.01), and the expressions of TLR4/NF-κB/TGF-β1 of ADRN group increased significantly.However, compared with ADRN group, the(P<0.01) level of Cr, BUN, 24 urine protein of TGP-treated rats reduced(P<0.01), the degree of fibrosis of TGP-treated rats eased(P<0.05), and the expressions of TLR4/NF-κB/TGF-β1 of TGP-treated rats decreased significantly.ConcIusion TGP retards the process of fibrosis and reduces the pathological damage in adriamycin-induced rats by down-regulating the expression of TLR4/NF-κB/TGF-β1 signaling.

Objective To observe the clinical effect of digital acupoint pressure on sensory dysfunction in hemiplegic patients after stroke. Methods From March to December, 2015, 60 hemiplegic patients with sensory dysfunction after stroke were randomly divided into control group and observation group with 30 cases in each group. The control group received routine rehabilitation exercise, while the obser-vation group received digital acupoint pressure in addition. Fugl-Meyer Assessment for Sense (FMA-S), Fugl-Meyer Assessment for Motor (FMA-M) and modified Barthel index (MBI) were used to evaluate the sensory dysfunction, motor function and activities of daily living be-fore and eight weeks after treatment. Results After treatment, the scores of FMA-S, FMA-M and MBI increased in both groups (t>6.430, P<0.01), and the scores were higher in the observation group than in the control group (t>2.100, P<0.05). Conclusion Digital acupoint pressure can facilitate the recovery of sensory dysfunction, improve the motor function and the activties of daily living in hemiplegic patients after stroke.

Objective:To study the correlation between serum homocysteine (Hcy) and the staging of gastric cancer,by comparing the concentrations of patients with gastric cancer at different pathological staging.Methods:90 patients with benign gastric diseases and 138 patients with gastric cancer were selected and admitted by Shandong University Qilu Hospital during the date from Mar 2014 to Jun 2015.The patients with gastric cancer were divided into 4 groups,according to the 7th AJCC Cancer Staging.To compare the difference of the concentration levels of Hcy and Tumor marks in different groups and analyze the relationship between benign disease and gastric cancer,and analyze it correlation with different pathological stagings of gastric cancer.Enzymatic cycling assay was used for detecting serum Hcy.Results:The serum Hcy concentration level in benign disease was (1 2.31 ± 3.22) μ mol/L,and significantly lower than cancer group(1 6.19 ± 4.84) μ mol/L,the difference was statistically significant (P＜0.05):The serum Hcy concentration levels increased gradually from staging I to staging Ⅳ,and the concentration level in staging Ⅰ was (13.94 ± 4.07) μ mol/L,in staging Ⅱ was (15.49 ± 4.09) μ mol/L,in staging Ⅲ was (17.10 ± 4.79) μ mol/L,in stagingⅣ was (19.81 ± 5.77) μ mol/L,the differences among the four groups were statistically significant(P＜0.05).Spearman Rank Correlation analysis confirmed that,the Hcy concentration level was positively related with pathological staging(r=0.503,P＜ 0.001).Logistic regression analysis showed that,the serum Hcy concentration level is significantly correlated with gastric cancer,after the adjustment of other risk factors (OR=1.208,P=0.003).Conclusions:The serum Hcy concentration level is closely correlated with gastric cancer staging,and increase significantly with the cancer staging (from staging Ⅰ to staging Ⅳ),so itcan be used to evaluate the severity of gastric cancer.

Objective To analyze the clinical characteristics,diagnosis,differential diagnosis and treatment of gastrointestinal schwannoma.Methods Clinical data of 3 patients with gastrointestinal schwannoma were collected and retrospectively analyzed.Results Gastrointestinal bleeding or melena,anemia and epigastric pain were the most common presenting symptoms.The symptoms,physical signs and auxitiary examinations (such as X-ray,ultrasonography and gastrointestinal endoscopy) of gastrointestinal schwannoma had no value in differentiation.In all the 3 patients definite diagnosis was achieved only by postoperative pathology.Conclusion Gastrointestinal schwannoma are derived from the Schwann cells of nerves in gastrointestinal wall and are usually benign.Benign schwannomas can only be distinguished from the malignant ones on the basis of histological and immunohistochemical criteria.Surgical resection is the most effective treatment.

Objective By observing the effect of deeply needling Lianquan (CV23) plus acupuncture at the ten nape points on the deglutition function in post-stroke pseudobulbar palsy, to objectively evaluate the efficacy of deeply needling Lianquanplus acupuncture at the ten nape points in treating post-stroke pseudobulbar palsy.Method A total of 141 patients diagnosed with post-stroke pseudobulbar palsy were divided into a treatment group (71 cases) and a control group (70 cases) by following asimple-randomized design (random number table). The treatment group was intervened by deeply needling Lianquan plus acupuncture at the ten nape points, while the control group was intervened by conventional acupuncture. A month later, the general therapeutic efficacy, Kubota's water drinking test, Toshima Ichiro's swallowing assessment, and Standardized Swallowing Assessment (SSA) were evaluated, and the therapeutic efficacies of the two groups were compared.Result The general therapeutic efficacy, waterdrinking test result, Toshima Ichiro's swallowing assessment, and SSA score were significantly improved in both groups after the treatment (P<0.05). After the treatment, the general therapeutic efficacy, water drinking test result, Toshima Ichiro's swallowing assessment, and SSA score in the treatment group were significantly different from those in the control group (P<0.05), and the treatmentwas superior to the control group. The total effective rate was 91.5% in the treatment group, versus 70.0% in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Deeply needling Lianquan plus acupunctureat the ten nape points is effective in treating post-stroke pseudobulbar palsy, superior to the conventional needling method.

Objective To observe the therapeutic efficacy and action mechanism of muscle-region alignment electroacupuncture in treating post-stroke shoulder pain. Method Eighty patients were randomized into a muscle-region alignment needling group and a conventional acupuncture group. The Short-form McGill Pain Questionnaire (SF-MPQ), and serum levels of IL-6, TNF-?, and NO were majorly observed before and after the treatment. Result The muscle-region alignment electroacupuncture and conventional acupuncture both obviously reduced the SF-MPQ score and down-regulated the serum levels of IL-6, TNF-?, and NO, and the decreases by the muscle-region alignment electroacupuncture were more significant than that by the conventional acupuncture. Conclusion The action of muscle-region alignment electroacupuncture in treating post-stroke shoulder pain is plausibly by down-regulating serum levels of IL-6, TNF-?, and NO, reducing or inhibiting the production of inflammatory factors and restraining inflammation.
