Medical Journal of Chinese People's Liberation Army 2001;0(09):-
Objective To analyze the clinical results and risk factors according to cause-specific survival and local recurrence rates for the patients with Ⅰ-Ⅱstage breast cancer after breast conservative therapy(BCT).Methods During Jun.1988 to Jun.2005,304 patients with Ⅰ-Ⅱstage breast cancer in the General Hospital of PLA underwent lumpectomy,axillary lymph node dissection and definitive irradiation.All patients received adjuvant chemotherapy.The patients with positive estrogen hormone receptors received orally tamoxifen administration.The median follow up was 8.1 years.Results For all the patients,the total 5-year survival rate,cause-specific survival rate and local recurrence-free survival rate were 92.58%,93.46% and 86.26%,respectively.And the total 10-year overall survival rate,cause-specific survival rate and local recurrence-free survival rate were 85.29%,88.27% and 77.75%,respectively.The 5-year and 10-year local recurrence rates were 5.5% and 11.7%,respectively.The univariate and mutivariate analyses revealed that the age(4)were the risk factors according to cause-specific survival rates.The age(

Objective To investigate the expression of glucose transporter 3(GLUT 3) transcription level at different ischemic time in rats' focal cerebral ischemic penumbra and core of cortices.Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) in rats were made by inserting nylon surgical thread. Brain samples were harvested from ischemic penumbra and core of cortices. The change of GLUT 3 mRNA was assessed by RT PCR.Results GLUT 3 mRNA in the penumbra regions slightly increased at 3 h after ischemia, and reached a peak at 24 h, in 96h following ischemia it came back to the normal level. As for ischemic core regions, GLUT 3 mRNA had a short time increase at 3 h after ischemia, and then rapidly decrease to the low level. Conclusion GLUT 3 mRNA expression was notably up regulated in the penumbra regions after focal cerebral ischemia,it may be a protective reaction against ischemic injury.

Objective To investigate the systemic stress responses after laparoscopic resection in colorectal cancer patients.Methods Sixty patients were randomized into the laparoscopic resection group (30 cases) and open resection group (30 cases) from October 2001 to September 2002 in our hospital.Analgesic dosages, recovery time of intestinal peristalsis, postoperative temperatures, C reactive protein(CRP), IL 6 and white blood cell (WBC) counts were recorded after operation. Results The changes of postoperative temperatures and WBC counts showed no significant difference between two groups.But in the laparoscopic resection group, the recovery time of intestinal peristalsis, postoperative analgesic dosages, CRP and IL 6 significantly decreased ( P

Objective To investigate the effect of CDA-II on apoptosis of breast cancer cells. Methods The effects of CDA-II on growth curve, cell apoptosis and morphology of breast carcinoma cell lines MCF-7 and MDA-MB-231 were observed by in vitro cultures, and compared with the classical cell differentiation inducer ATRA. MCF-7 and MDA-MB-231 cell lines have their different biologic characteristics. Results CDA-II can reduce growth and proliferation ability and induce cell apoptosis of breast cancer cell lines( MCF-7 and MDA-MB-231). Conclusions CDA-II has remarkable effect of anti-cell-proliferation and induction of (apoptosis) on breast cancer cells MCF-7 and MDA-MB-231 . Our results provide experimental bases for the treatment of breast carcinoma with CDA-II.

Objective To investigate the effect of CDA-Ⅱ on the cell cycle progression of breast cancer cells.Methods The effects of CDA-Ⅱ on growth curve, cell cycle progression and morphology of breast cancer cell lines MCF-7 and MDA-MB-231 were observed when CDA-Ⅱ and MCF-7 or CDA-Ⅱ and MDA-MB-231 were blended to cultivate in vitro, in comparison with the classical cell differentiation inducer ATRA. Results CDA-Ⅱ decreased the growth speed and inhibit proliferation ability in breast cancer cell lines MCF-7 and MDA-MB-231.It caused G0/G1 phase block of cell cycle and reduced the rate of S phase of breast cancer cells. Conclusion CDA-Ⅱ has remarkable effect of anti-cell-proliferation and can induce cell cycle block of G0/G1 on breast cancer cells. This results provide experimental bases for the treatment of breast cancer with CDA-Ⅱ.

Objective To analyse the clinical data of 77 patients with unsuspected gallbladder carcinoma,and to determine the impact of TNM stage and the timing of the second operation on postoperative survival.Methods A retrospectively analysis of 77 patients operated between January 2008 and January 2013 in our hospital for unsuspected gallbladder carcinoma was carried out.The case inclusion criteria was in strict accordance with the medical records which described without preoperative diagnosis,or cholecystectomy for benign gallbladder diseases,or intraoperative or postoperative pathological diagnosis of gallbladder cancer.References to previous published medical literature and the intervals from initial cholecystectomy to further treatment were analyzed to see whether the prognosis and survival varied depending on the TNM staging and whether secondary radical surgery was carried out.Results For the 77 patients in this study,they all had high risk factors associated with gallbladder cancer which included:women,aged > 50 and gallbladder stones.The initial surgery included laparoscopic cholecystectomy (n =53),and open cholecystectomy (n =24).In 26 patients,intraoperative frozen section confirmed the diagnosis and they were treated according to the TNM staging (radical operation n =7,palliative surgery n =17).The postoperative 1-,2-,3-year cumulative survival rates were 65%,45% and 20%,respectively.For the 54 patients who underwent radical or extended radical cholecystectomy within a short interval from the first operation,the 1-,2-,3-year cumulative survival rates were 82.5%,62.5% and 45.7%,respectively.Conclusions For resectable gallbladder cancer,the prognosis of unsuspected gallbladder carcinoma was related not only to the clinical staging,but also to the timing of the radical operation.The shorter time interval,the longer the survival,and the better the prognosis.There was no significant difference in prognosis for the group of patients with time intervals between the two operations of less than two weeks when compared with the group with immediate radical surgery.For advanced stages of gallbladder cancer,palliative surgery should be given according to the patient's general condition,aiming to improve quality of life.

Objective To explore the correlation between homocysteine(Hcy),lipids amd type 2 diabetes mellitus (T2DM). Methods The laboratory test results of 533 cases of patients with T2DM(T2DM group)and 362 cases of healthy individuals (healthy control group)were retrospectively analyzed.Results The serum levels of Hcy and rates of abnormal serum cholesterol (TC),triacylglycerol(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)levels in the T2DM group were higher than those in the healthy control group,had statistically significant differences(P <0.05).Conclusion The high serum level of Hcy and abnormal lipid metabolism are correlated with T2DM,which might be risk factors of diabetes mel-litus and cardiovascular disease.

Aim To study the immunomodulatory activity of total flavonoids of Litsea Coreana Leveille (LCTF) on cyclophosphamide(CY)-induced immunosuppressive mice. Methods CY (50 mg?kg-1) was administered by intraperitoneal(ip)injection for 2 consecutive days to induce immunosuppressive model. Carbon clearance, quantitative hemolysis and DNFB-induced delayed-type hypersensitivity(DTH) were applied to assay effects of LCTF on nonspecific immunity, humoral immunity and cellular immunity. Results In carbon clearance test, the clearance index (K) and values of phagocytic index (?) were elevated by LCTF (200 and 400 mg?kg-1), indicating the phagocytosis of macrophages was enhanced in immunosuppressive mice.In quantitative hemolysis, productions of IgM and IgG in serum and hemolysin in splenocytes were enhanced in immunosuppressive mice by LCTF (100 and 200 mg?kg-1). LCTF (200 and 400 mg?kg-1) obviously increased DTH reactivity in immunosuppressive mice. LCTF not only increased percentages of T cells expressing CD4+ and CD8+,but also enhanced the ratio of the two subset of T lymphocyte,and LCTF (200 and 400 mg?kg-1) could also improve IL-2 production of spleen lymphocytes. Conclusion LCTF showed significant immunomodulatory property on immunosuppressive mice through specific and nonspecific immunity.
