3.The research progress on Notch signaling pathway in the regulation of Treg/Th17 cells
Tianjin Medical Journal 2018;46(5):548-552
Notch family,a kind of important transmembrane signaling proteins,is highly evolutionarily conserved in the development process of multicellular organisms. Notch signaling pathway can precisely regulate cell development process through the interaction between neighboring cells,such as cell proliferation,differentiation and apoptosis.The regulatory T (Treg)cells and T helper 17(Th17)cells are new types of CD4+T cell subsets.In the physiological state of the organism,they can secrete relevant various kinds of cytokines,and systematically regulate the balance of immune system.In recent years, more and more studies have found that close relationship between Notch signaling pathway and Treg/Th17 cell balance, which is extensively involved in the various diseases. Therefore, this paper briefly reviewed the regulation mechanism of Notch signaling pathway on Treg/Th17 cells in diseases such as hematological diseases and autoimmune diseases.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.

OBJECTIVETo consider the relationship to survival rate and quality of life with pararectal lymphadenectomy for lower carcinoma of rectum.
METHODSThe radical operation was performed on 780 cases of progressive cancer located at peritoneal reflection or below it, Among them, 352 cases only cleared in abdominal cavity, 428 cases coupled with extra-peritoneal histopathological type.
RESULTSUrinary function injured, the group cleared in abdominal cavity was 12 cases, accounted for 3.6%; the group coupled with extra-peritoneal clearance was 225 cases, for 52.5% (P < 0.01). Sexual function damaged (only for male), the abdominal cavity group was 23 cases, for 12.6% (23/185); the coupled group was 127 cases, for 53.4% (127/238), (P < 0.01). Local relapse rate, the abdominal cavity group was 15.8% (56/352); the coupled group was 8.6% (41/428), (P < 0.05). 5-year survival rate, the abdominal cavity group was 52.2%; the coupled group was 58.5% (P < 0.05).
CONCLUSIONBy contrast, although abdominal cavity coupled with extraperitoneal lymphadenectomy acted to cut down local relapse and to elevate 5-year survival rate, the postoperative quality of life appeared to be seriously affected.

OBJECTIVETo investigate the essentials of operation and the postoperative effect of right hemicolonic carcinoma with anterograde clearance of lymph nodes.
METHODSOne hundred and thirty-five patients with right hemicolonic infiltrated carcinoma, who were eligible for radical excision (D(3)), were divided into 2 groups. Among them, the anterograde clearance of lymph nodes was performed on 56 cases; the retrograde clearance was performed on 79 cases. Both groups showed no significant difference in age, sex, Dukes' staging and pathological type.
RESULTSThe average time of operation: the anterograde group was (180 +/- 40) min; the retrograde group was (180 +/- 20) min. The average amount of bleeding: the anterograde group was (200 +/- 80) ml; the retrograde group was (200 +/- 30) ml. The cleared number of lymph nodes: the anterograde group were 6.3 +/- 4.2, 2.6 +/- 3.1, 1.5 +/- 2.3 in paracolon, middle and radicel of vasorum respectively, the total number was 11.4 +/- 8.6; the retrograde group were 6.4 +/- 2.2, 2.8 +/- 2.1, 1.1 +/- 1.1 respectively, the total number was 10.8 +/- 5.6 (P > 0.05). The postoperative metastasis to liver: the anterograde group was 8 cases (13.9%); the retrograde group was 21 cases (26.6%, P < 0.05). The 5-year survival rate: the anterograde group was 72.8% (41/56); the retrograde group was 65.5% (52/79) (P < 0.05).
CONCLUSIONSThe operative technique of the excision was little difficulty and complexity, and it could fit well with the requirement of non touch isolation, and act to cut down the postoperative metastasis to liver and to elevate 5-year survival rate.

OBJECTIVESTo evaluate the effect and the indication of local resection for rectal cancer below the peritoneal reflection.
METHODSOne hundred and thirty-four patients with early rectal carcinoma whose masses were >or= 5 cm or RESULTSNo recurrence appeared in 47 patients with intra-mucosal carcinoma (M-Ca). In 87 patients with submucosal carcinoma (SM-Ca), 3 patients were positive for the cutting end, 8 showed vessel infiltration, and 5 showed low-differentiated adenocarcinoma. These patients had to accept mile's operation, but one patient had local recurrence and 2 patients had liver metastases. Two patients had local recurrence and 8 had metastasis of the liver and other sites. The total 5-year survival rate was 94%. CONCLUSIONSTrans-sacral local resection is an optimal operation since the operative range is small and artificial anus is avoided. However, it is only suitable for early rectal carcinoma. When vessel infiltration or low differentiation or positive cutting end are confirmed, radical operation should be added.

Objective To investigate the effect of single dose intraosseous injection of simvastatin on tumor vascular structure and function in murine breast cancer. Methods BALB/c mice and 4T1 murine breast cancer cells were used to establish a subcutaneous xenograft model. The mouse model of orthotopic breast cancer received intraosseous injection of a single dose of simvastatin (50 μg) or vehicle only. Frozen tumor tissue sections were prepared for co-immunostained with CD31 andα-SMA. Evans blue dye was injected into the tail vein to observe the vascular permeability. The expression level of HIF-1αwas detected by immunohistochemistry. Results Immunofluorescence dual staining showed that intraosseous injection of simvastatin increased the number of perivascular pericytes in the tumor vessel(P < 0. 05), Evans blue dye content showed that in vivo vessel permeability in the tumor tissue was significantly decreased(P < 0. 05), and the immunohistochemistry results showed that local hypoxic area was significantly improved. Conclusions Single dose intraosseous injection of simvastatin can promote the normalization of tumor vasculature by improving the coverage of pericytes.

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.
