AIM: To study the effect of IL-12 on T lymphocytes apoptosis, the expression of Fas/FasL and TNFR/TNF?. METHODS: Terminal dUTP nick end labeling(TUNEL) and Annexin V assay were used. Anti-TNFR were labeled with FITC, anti-CD95 was labeled with PE and Anti-FasL with biotin. Three kinds of T cells (HTB176,TIB152 and human normal T cells) were analysed through flow cytometry. RESULTS: At 1st hour after being treated with IL-12, the expression of FasL protein and FasL mRNA in HTB176 and TIB152 began to increase and reached peak value in 24 hours. In the normal T cells, FasL just began to increase in 1 hour and maintained stability in 6, 12 and 24 hours through the later experiment period. All three kinds of T cells displayed no change in the expression of CD95 and TNFR/TNF? under the stimulation of IL-12. CONCLUSION: Expression of such apoptosis regulating factors were different in the apoptosis of T cells induced by IL-12.

In this research project, rats were made into animal models of acute focal cerebral ischemia and reperfusion (IR) by occlusion of their middle cerebral artery (MCAO). We observed the effect of endogenous endothelial progenitor cells (EPCs) and serum cytokines on cerebral ischemia rats treated by electro-acupuncture(EA). The results showed: MCAO model had high stability after EA treatment which was delivered via the acupuncture needles inserted into "quchi" and "zusanli" points, the nervous functions of cerebral IR rats recovered faster than those of rats not treated; EPCs in rats' blood increased after acute focal cerebral ischemia and reperfusion; and the growth rate was obvious in IR group. This phenomenon might be related to the inflammation elicited by injury of ischemia and self-repair. Besides, EA treatment could decrease induced nitric oxide synthase (iNOS) activity, alleviate injury after cerebral ischemia, and regulate the quantity of EPCs in blood. The quantity of EPCs in blood increased in IR-24hr. In IR-48 hr, the rise of EPCs quantity was significant (P < 0.01). The level of vascular endothelium growth factor (VEGF) in serum of rats after cerebral ischemia was escalated, which indicated to a certain extent that cerebral ischemia could stimulate stress reaction. EA treatment could raise VEGF level, which suggested that high expression of VEGF could accelerate mobilization, chemotaxis and homing of EPCs. At the same time, the levels of matrix metalloproteinase-9 (MMP-9) and basic fibroblast growth factor (bFGF) also changed. In conclusion, EA treatment could promote neovascularization after cerebral ischemia by mobilizing EPCs, decreasing iNOS activity and increasing VEGF level. This may be one of the ways by which EA could treat cerebral ischemia.

A series of 4-(N-aryl)amino-6-alkoxyl pteridine derivatives was designed and synthesized via the bio-isostere principle using anti-cancer drugs with quinazoline cores as lead compounds.The proliferative inhibitory activities of the synthesized compounds against tumor cells A549,KG1a and HGC-27 were also performed by MTT assay.Using methyl 3-aminopyrazine-2-carboxylate as the starting material,12 target compounds(7a-7l)were synthesized through six-step reaction, and characterized by 1H NMR, 13C NMR and MS.It was showed that antitumor activity of pteridines with 2-chloro-5-nitro-anilino substituted in position 4 was more potent than that of others.The activity of compound 7b on A549 cells(IC50=11.55 μmol/L)was closely approximate to that of positive control gefitinib(IC50=5.95 μmol/L).IC50values of compound 7k on three cell lines were all close to those of gefitinib.A 2-chloro-5-nitro-anilino fragment was contained in preferred compounds which might be modified for further investigation.

Purpose: This study aims to elucidate the longitudinal alterations in frailty and health-related quality of life experienced by elderly patients undergoing surgical treatment for esophageal cancer. Additionally, it seeks to ascertain the impact of preoperative frailty on postoperative health-related quality of life over time. Methods: 131 patients were included in the prospective study. Patients' frailty and health-related quality-of-life were assessed utilizing the Tilburg and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at preoperative, 1 week, 1 month, and 3 months, postoperatively. Statistical analyses were performed using generalized estimating equations, repeated-measures analysis of variance, and linear mixed models (LMMs). Results: Out of 131 patients, 28.2% had frailty before surgery, and the prevalence of frailty consistently higher after surgery compared with baseline (67.9%, 51.9%, and 39.7%). There was no significant change in frailty scores in preoperative frail patients within 3 months following surgery (p = .496, p < .999, p < .999); whereas in preoperative non-frail patients, the frailty scores increased at 1 week (p < .001) and then decreased at 1 month (p = .014), followed by no change at 3 months. In addition, preoperative frail patients had significantly worse global quality-of-life (β = −4.24 (−8.31; −.18), p = .041), physical functioning (β = −9.87 (−14.59; −5.16), p < .001), role functioning (β = −10.04 (−15.76; −4.33), p = .001), and social functioning (β = −8.58 (−15.49; −1.68), p = .015), compared with non-frail patients. Conclusions A significant proportion of participants exhibited a high prevalence of preoperative frailty. These patients, who were preoperatively frail, exhibited a marked reduction in health-related quality-of-life, a more gradual recovery across various functional domains, and an increased symptom burden during the follow-up period. Therefore, it is crucial to meticulously identify and closely monitor patients with preoperative frailty for any changes in their postoperative physiology, role, and social functioning.
