OBJECTIVE: To study the effects of Lycium barbarum polysaccharide (LBP) on tumor microenvironment T-lymphocyte subsets and dendritic cells in H22-bearing mice and the mechanisms for intervention of tumor immune escape by LBP. METHODS: H22-bearing mice were given LBP orally for two weeks. T-lymphocyte subsets and the phenotypes of dendritic cells in tumor-infiltrating lymphocytes (TIL) were detected by flow cytometry (FCM). RESULTS: LBP could significantly increase the numbers of CD4(+) and CD8(+) T cells in TIL as compared with those in model control group (P<0.05). In model control group, the number of dendritic cells in tumor microenvironment decreased markedly, while in LBP-treated group, the increased number of dendritic cells and B7-1 expression were observed, but there were no significant differences between these two groups. CONCLUSION: LBP has anti-tumor effect probably by increasing the numbers of CD4(+) and CD8(+) T cells in TIL to relieve the immunosuppression and enhance the anti-tumor function of the immune system. But whether LBP can recover the phenocyte and function of dendritic cells in H22-bearing mice should be further studied.

BACKGROUND:Tumor recurrence results from the incomplete removal of cancer stem cel s with self-renewal characteristics, and then how to label and eliminate cancer stem cel s becomes the key to cancer treatment. OBJECTIVE:To observe the morphology,distribution and number of CD44+/C-myc+METHODS:Pathological tissues from 150 patients with colorectal cancer were taken to prepare tissue microarray, in order to observe and count CD44 cel s in colorectal cancer, and to explore the relationship between the expression and postoperative metastasis.+/C-myc+cel s by using immunohistochemical double staining. Patients were fol owed up through mobile phones , letters , and so on, and the relationship between the expression of CD44+/C-myc+cel s and postoperative metastasis were statistical y recorded.RESULTS AND CONCLUSION:There was no CD44+/C-myc+cel s in normal tissue and little in adenoma. A smal number of CD44+/C-myc+cel s distributed as dots or focal lesions in adenocarcinoma. The number of CD44+/C-myc+cel s was related to the degree of adenocarcinoma differentiation, depth of invasion, and lymph node metastasis (P<0.05). The univariate analysis showed that the overal survival rate and progression-free survival rate were associated with the number of CD44+/C-myc+cel s, lymph node metastasis and Ducks staging in adenocarcinoma (P<0.05). The multivariate analysis showed that the overal survival rate was related to CD44+/C-myc+cel amount and the progression-free survival rate was related to CD44+/C-myc+cel amount and the Ducks staging. Therefore, CD44+/C-myc+cel s are probably cancer stem cel s, and Ducks staging and CD44+/C-myc+cel amount are important prognostic factors for colorectal cancer.

Objective To investigate the clinical therapeutic effect of electroacupuncture on ischemic stroke by recording the therapeutic effect score and performing transcranial Doppler (TCD) detection in electroacupuncture-treated convalescent stroke patients before and after treatment.Methods Sixty convalescent patients with ischemic stroke were randomly allocated to treatment and control groups, 30 cases each. The control group received routine medication and the treatment group, electroacupuncture in addition. In the two groups, pre- and post-treatment neurological defect scores were recorded and the clinical therapeutic effects were observed after four weeks of treatment. Pre- and post-treatment middle cerebral artery (MCA) pulsation indices (RI), resistance indices (RI) and ratios of systolic to end-diastolic (S/D) blood flow velocity detected by TCD were compared between the two groups. Results The total efficacy rate was 80.0% in the treatment group and 50.0% in the control group; there was a statistically significant difference between the two groups (P<0.01). There was a statistically significant pre-/post-treatment difference in the MESSS score in the two groups (P<0.01). There was a statistically significant post-treatment difference in the MESSS score between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in TCD indices (PI, RI and S/D) on the affected side in the two groups (P<0.05). There were statistically significant post-treatment differences in TCD indices on the affected side between the treatment and control groups (P<0.05).Conclusion Electro- acupuncture can promote rehabilitation in convalescent stroke patients.

prognosis of patients with acute upper gastrointestinal bleeding (AUGIB). Methods A total of 130 patients with AUGIB in our hospital were enrolled in this study from August 2014 to August 2016 . Three kinds of scoring systems including Rockall, Blatchford and AIMS65 were used to evaluate the risk classification of the patients. Patients were followed up for 2 months. The incidence rates of re-bleeding and death within 2 months after admission were observed. Data of prognosis in patients with AUGIB were compared between the three scoring systems in the prognosis of patients with AUGIB, including the risk classification and the prediction accuracy of re-bleeding and death. Results There were no significant differences in the re-bleeding rate and fatality rate between the groups divided by Rockall and Blatchford scoring systems ( P>0.05). According to the grouping results of AIMS65 scoring system, the re-bleeding rate of low-risk group was lower than that in high risk group (1.45%vs. 13.11%, P=0.01), but there was no significant difference in fatality rate between the two groups (P>0.05). The values of area under the curve (AUC) of predicting re-bleeding rates by using Rockall, Blatchford and AIMS65 scoring systems were 0.6258, 0.6910, and 0.7241, and the values of AUC of predicting fatality rates were 0.7031, 0.7969, and 0.7031 by using receiver operating characteristic curve (ROC) analysis. There were no significant differences between them (P>0.05). The values of AUC of predicting re-bleeding rates by using the risk grading calculation by Rockall, Blatchford and AIMS65 scoring systems were 0.6189, 0.6139 and 0.7254 (P>0.05). But the values of AUC of predicting fatality rates were 0.6211, 0.6641 and 0.7695 (P<0.01). Conclusion The operation method of AIMS65 scoring system is simple and convenient, which is applicable to a wide range of patients with AUGIB. In the prediction of re-bleeding and mortality, AIMS65 scoring system has high accuracy and stability, which is worthy of promoting in clinical application.
