Objective To investigate the change of CD_4~+CD_(25)~(high)CD_(127)~(low)> regulatory T cells (Trcg cells) sub-group level in peripheral blood of non-Hodgkin lymphama (NHL) patients, and to explore its clinical significance. Methods Treg cells levels in peripheral blood of lymphoma patients and normal were detected by flow cytometry, followed by statistical analysis. Results In the 65 cases of NHL patients, Treg cells in peripheral blood were (6.72±1.38) %, higher than that in the normal control group (5.65±0.68) % (P <0.05). Percentage of Treg cells are significantly different between clinical stages and normal: [P <0.05, normal control group (5.65±0.88) %, Ⅰ -Ⅱ period (6.08±1.18) %, Ⅲ-Ⅳ period (6.95±0.85) %]. The percentage of Treg cells are also different among pathological types of patients and normal [P <0.05, normal control group (5.65± 0.68) %. The percentage of Treg diffuse large B-cell lymphoma (5.83±0.95) % and other subtypes of lymphoma (7.83±1.76) %]were observed. It is not sure that Treg cells percentage among patients with different levels of lactate dehydrogenase and normal are significantly different. [P >0.05, normal control group (5.65±0.68) %, patients with normal LDH group (6.97±1.20) %, patients with lactate dehydrogenase (6.54±1.02) %]. Conclusion Treg cells induced by tumor and could inhibit the immune cells, Treg cells percentage in peripheral blood of tumor patients is higher than that the normal control group, and increased with the clinical staging, so the percentage of Treg cells may serve as a clinical indicator to evaluate tumor load.

Objective To explore the clinical significance of T lymphocyte subsets and NK cells' detection in peripheral blood of patients with non-Hodgkin' s lymphoma (NHL).Methods 62 newly diagnosed NHL and 30 healthy adults were enrolled for analyzing.T lymphocyte subsets and NK cells were deteced by flow cytometry and compared between different groups according to age,sex and pathology.Multiple linear regression was used to analyze the correlation among the levels of T lymphocyte subsets and NK cells and several clinical factors,such as clinical stage,IPI and B symptoms.Results The proportions of CD3,CD4 and NK cells in peripheral blood of NHL group [(64.13±19.83) ％,(27.10±8.20) ％,(13.51± 10.59) ％] were significantly lower than those of normal control [(65.78±10.69) ％,(31.95±12.74) ％,(18.76± 7.36) ％] (P ＜ 0.05),while the proportions of CD8 and Treg cells in peripheral blood of NHL [(32.15±13.83) ％,(10.44±3.00) ％] were significantly higher than those of normal control [(29.25±12.35) ％,(7.51±4.36) ％] (P ＜ 0.05).In NHL,the proportions of CD3 and NKT cells [(67.06±19.24) ％,(4.91±3.69) ％] in ≤60 years old group were significantly higher than those in ＞ 60 years old group [(59.18±20.33) ％,(4.89±3.05) ％] (P ＜ 0.05).The proportions of Treg cells in T-NHL was significantly higher than that in B-NHL [(8.17±6.41) ％ vs (7.11±2.53) ％] (P ＜ 0.05).The proportions of CD3,CD4,NK and NKT cells in peripheral blood of NHL were significantly correlated with clinical stage (P ＜ 0.05),that of CD8 cells were significantly correlated with IPI (P =0.000),that of Treg cells were significantly correlated with IPI and B symptoms (P ＜ 0.05).Conclusion The cellular immune is suppressed in NHL patients.The proportions of T lymphocyte subsets and NK cells in peripheral blood of patients with NHL are different between different groups according to age,sex and pathology.The correlations among that and clinical factors need to be further explored.

Objective:To explore the effects of humanized nursing and personalized service in operating room nursing.Methods:A total of 300 patients who underwent surgical surgery in our hospital from April 2016 to June 2016 were randomly divided into the intervention group (n =150) and control group (n =150).Patients in the control group were treated with routine nursing care.On this basis,patients in the intervention group were provided with integral perioperative nursing of humanized nursing and personalized service.The fear,anxiety,blood pressure and heart rate fluctuations of both two groups before and after entering operating room were statistically analyzed.Results:Before entering operating room,the fear and anxiety scores of the patients in the intervention group were (32.67 ± 12.27),the blood pressure was (97.5 ± 12.8) mmHg,and the heart rate was (93.7 ± 11.8).The fear and anxiety scores in the control group were (36.94 ± 12.78),the blood pressure was (99.8 ± 12.5) mmHg,and the heart rate was (105.4 ± 10.6).The intervention group was significantly lower than the control group (P ＜ 0.05).Conclusion:The implementation of humanized nursing and personalized service can effectively reduce the patient's fear and anxiety to make the heart rate,blood pressure and other vital signs be in a relatively stable state;can make patients calm,positive and optimistic to undergo the surgery and actively cooperate with doctors and ward nursing,thus to get well soon.

Background contamination is a major problem in the analysis of organophosphate esters (OPEs). In this study, the possible sources of OPEs pollution were screened and several different ways were applied to minimize the blank contamination. Under the strict quality control measures, the cleanup efficiency of different solid phase extraction (SPE) was investigated for OPEs in different environmental matrices. A method was developed for the detection of 7 OPEs in dust, soil and sediment samples by gas chromatograph coupled with mass spectrometry ( GC / MS). Target compounds were extracted by hexane:dichloromethane (1 : 1, V/ V) followed by aminopropyl silica gel SPE column cleanup for dust, and target compounds in soil and sediment were Soxhlet extracted and cleanuped by two-step SPE. The results showed that the aminopropyl silica gel SPE column displayed the best purification performance among the three employed columns. Instrumental detection limits among the 7 OPEs ranged from 2. 5 to 25. 8 μg / L, and the method limits of quantification (MLOQs) in dust and soil sample ranged from 1. 4 to 15. 7 ng / g and 0. 3 to 2. 9 ng / g, respectively. The average recoveries of 7 OPEs in different matrices ( dust and soil) at two spiked concentration levels ranged from 67. 9% to 117. 4% . The proposed method was successfully applied to detect OPEs in different environmental matrices collected in Shanghai.

Objective To explore the variations and prognostic factors of hyperhomocysteinaemia in ischemic cerebral apoplexy for the youth who administrated vitamin B6,vitamin B12 and folic acid at pretherapy and post-treatment.Methods One hundred and twenty cases of young patients with ischemic cerebral apoplexy in the Pinggu Hospital of Capital University from January 2003 to December 2013 as case group(intervention group,60 cases and 60 cases of non-intervention group),while 120 youth volunteers with the same period and age without neurological diseases as a control group.Both groups patients were detected for hyperhomocysteinaemia,folic acid and vitamin B12.The non-intervention group was administrated basic treatment,while the intervention group administrated vitamin B6,vitamin B12 and folic acid on this basis.The hyperhomocysteinaemia,folic acid and vitamin B12 were detected repetitively after four weeks.Results Compared with control group,the hyperhomocysteinaemia in ischemic cerebral apoplexy group for the youth had increased significantly ((10.2 ± 3.1) μmmol/L vs.(21.3 ± 4.5) μmmol/L,P ＜ 0.05).The hyperhomocysteinaemia,folic acid and vitamin B12 had no significant differences between intervention group and non-intervention group (P ＞ 0.05).After replenished vitamin B6,vitamin B12 and folic acid,the hyperhomocysteinaemia had decreased significantly ((10.5 ± 3.0) μmnol/L) in intervention group.Folic acid ((6.5±2.8)μg/L) and vitamin B12(450.2±155.6) ng/L) had increased significantly(P＜0.05).Conclusion The hyperhomocysteinaemia increased in ischemic cerebral apoplexy for the youth.It is that hyperhomocysteinaemia decreased by replenished vitamin B6,vitamin B12 and folic acid which make for prognosis in ischemic cerebral apoplexy for the youth.
