Chinese Journal of Dermatology 1995;0(04):-
The same paraffin-embedded specimen of skin biopsy from each of 29 patients with cutaneous malignant lymphomas (CML) and 7 patients with cutaneous lymphoid infiltrates (CLI) was estimated simultaneously and retrospectively by karyomorphometry and proliferating rate assay. The results showed that the differences in nuclear volumes (NVs), count of argyrophilic nucleolar organizer regions(AgNORs) and proliferating cell nuclear antigen (PCNA-PC10) indices (PC10Is) between CML and CLI were statistically very significant. The NVs and PC10Is were correlated to the death rate of patients. NVs were also correlated to AgNORs.

Chinese Journal of Tissue Engineering Research 2007;0(15):-
BACKGROUND: As a multifunctional cell growth factor, vascular endothelial cell growth factor (VEGF) plays various biological roles under some physiologic and pathologic conditions. OBJECTIVE: To summarize molecular structure and biological effects of VEGF. RETRIEVAL STRATEGY: A computer-based online search of PubMed database was undertaken to identify related English articles dated from January 1989 to December 2007 with keywords"VEGF, molecular structure, biological effect, diabetes, diabetic macroangiopathy". 934 articles were firstly collected, including 38 about molecular structure and biological effects of VEGF, and 896 about diabetes and diabetic macroangiopathy. After the first trial, only articles about ①molecular structure and biological characteristics of VEGF, and ②diabetes and diabetes complicated by coronary heart disease or limb vascular disease were selected. 897 repetitive, outdated and unrelated articles were excluded. Finally, 35 articles were included. LITERATURE EVALUATION: Of 35 articles, there were 17 ones about animal trials, and in vivo, in vitro and cytological studies, 8 of review articles and comments, and 10 clinical studies. All articles were individual evaluation. DATA SYNTHESIS: Human VEGF genes consist of 8 exons and 7 introns, and are located in 6p21.3 region. VEGF encodes several isoforms with different biological characteristics. Two VEGF receptors display different biological effects. VEGF and its receptors are regulated by various factors. The receptors interact with ligand and play biological effect. In diabetic patients complicated by coronary heart disease, myocardial VEGF mRNA and protein expressions are increased but the expressions of two kinds of receptors are decreased compared with non-diabetic patients. Compared to patients with non-severe lower limb ischemia, VEGF production is more in diabetic patients complicated by severe lower limb ischemia. It is demonstrated that VEGF can restore injured neovascularization. However, VEGF therapy for diabetes still needs further study. CONCLUSION: VEGF can restore impaired neovascularization. VEGF expression shows diversity under diabetic macroangiopathy. Further study should be made focusing on the prevention value of VEGF to diabetic macroangiopathy.

Objective:To evaluate the effect of nutritional status on postoperative outcomes for patients with gastric cancer. Methods:Data of 353 gastric cancer patients at Xinjiang Medical University Affiliated Tumor Hospital between January 2013 and October 2014 were collected prospectively. Preoperative nutritional status was evaluated using Nutrition Risk Screening 2002 (NRS 2002). Postoperative complication rates were compared among different preoperative nutritional status. Results:On the basis of NRS 2002, the morbidities of patients with and without malnutrition risk were 47.0%(77/164) and 31.2%(59/189), respectively (P=0.002). Among the patients with an NRS score of at least 3, the complication rate was significantly lower in the group with preoperative nutrition than in the group of patients without preoperative nutrition support (P=0.013). NRS 2002 was a significant predictor of postoperative complications (P=0.039, OR=1.634, 95%CI:1.025-2.606) on the basis of multivariable logistic regression analysis. Conclusion:As a nutritional evaluation tool, NRS 2002 may predict postoperative complications for gastric cancer patients.

As a distinct T cell subset with acknowledged specific function and marker, CD4+CD25+FOXP3+ regulatory T cells are thought to dampen T-cell immunity and to be the main obstacle tempering antitumor immunotherapy. Accumulating evidence has confirmed an increased pool of regulatory T cells both in the peripheral blood and the tumor microenvironment of cancer patients, which are indicative of disease progression, response to therapy, invasive phenotype and prognosis. Therefore, manipulation of regulatory T cells—including depletion, blocking trafficking into tumors, or reducing their differentiation and suppressive mechanisms—and concomitant stimulation of effector T cells, systemically or locally in tumors, represent new strategies for cancer treatment.
