Objective To compare the proportion of CD3~+T cell and CD4~+CD25~(high) regulatory T cell (Treg cell) and the production of inferon γ ( IFN-γ) and interleukin-12 (IL-12) in peripheral blood mononuclear cells (PBMC) between patients with non-small cell lung cancer (NSCLC) and healthy people, and to analyze the changes of CD3~+T cell, CD4~+CD25~(high)Treg cell, IFN-γ and IL-12 of NSCLC patients before and after chemotherapy, so as to determine immune function changes of NSCLC patients caused by chemotherapy. Methods Twenty NSCLC patients and 20 healthy volunteers according to the including criteria were selected. Three mL of blood was drawn from NSCLC patients before chemotherapy (0 d), on the 3~(rd) day (3 d) and 7~(th) day (7 d) after chemotherapy. PBMC cells were separated from the blood samples. The proportions of CD4~+CD25~(high)Treg cell and CD3~+T cell (%) in PBMC were tested by FACS, and the IFN-γ and IL-12 (pg/mL) in the supernatants were also detected. Results The proportions of CD3~+T cell in NSCLC patients on 0, 3 and 7 d were (55.15±20.11)%,(57.73±14.08)% and (62.79±7.80)%,respectively, and there was no statistical difference between any two of these results. The proportion of CD4~+CD25~(high)Treg cell in healthy volunteers was (2.14±0.85)%, while that of NSCLC patients was (2.76±0.53)% on 0 d with statistical difference compared to the healthy volunteers (P<0.05). The CD4~+CD25~(high)Treg cell proportion (%) of NSCLC patients on 3 d and 7 d were (2.54±0.57)% and (2.72±0.29)%, respectively, which were both significantly lower than that of 0 d. On 3 d it was even much lower than that on 7 d (P<0.05). IFN-γ and IL-12 of NSCLC patients on 0 d were (34.36±4.38) pg/mL and (33.24±4.36) pg/mL, and no statistical difference was observed when compared with (34.36±4.38) pg/mL and (33.24±4.36) pg/mL in the healthy volunteers. On 3 d and 7 d, IFN-γ of NSCLC patients were (40.42±5.66) pg/mL and (39.27±6.07) pg/mL, respectively, and both were higher than that on 0 d (P<0.05); IL-12 of NSCLC patients were (35.51±5.03) pg/mL and (38.62±6.44) pg/mL, also both were higher than that on 0 d (P<0.05). Conclusions This study suggests that chemotherapy can improve immune functions of NSCLC patients, and may reinforce the anti-tumor immune response.

BACKGROUND:Clinical application of neural stem cells is under exploration.Currently,the indicative differentiation of neural stem cells into specific neurons to replace lost and degenerative neurons needs to solve.OBJECTIVE:To explore the effect of 83 ku protein in rat hippocempi on inducing neural stem cell differentiation into acetylcholine esterase (ACHE) positive neurons.DESIGN,TIME AND SETTING:In vitro controlled observation of cytology was performed at the Medical College of Nantong University between October 2003 and April 2008.MATERIALS:A total of 12 SD rats,of clean grade,and SD fetal rats,aged 17 days,were provided by the Experimental Animal Center of Nantong University.METHODS:The normal hippocampi and hippocampi on the 14th day after the hippocampal fimbria transection were prepared into homogenate used for 10% native-polyacrylamide gel electrophoresis,and the differential proteins of 83 ku were electroeluted.The protein concentration was adjusted to 300 mg/L.The forebrain tissues of fetal rats were harvested and neural stem cells were isolated and in vitro cultured:blank control cells were cultured in serum-free DMEM/F12 medium;83 ku normal and 83 ku transection groups were separately cultured in serum-free DMEM/F12 medium containing 10 mg/L 83 ku protein from normal and hippocampal fimbria transection rats for 12 days.MAIN OUTCOME MEASURES:AChE histochemical staining was used to detect the differentiation of neural stem cells into AChE positive neurons.RESULTS:After 12 days of culture,there was a large amount of AChE positive neurons in 83ku transection group and their bodies were very big and the processes were abundant;The AChE positive neurons in 83ku normal group were less than 83 transection group,and their bodies were small with short processes.A few of AChE positive neurons were seen in control group.There were significant differences in number of AChE positive neurons among three groups (P＜0.05).CONCLUSIONHippocampal 83 ku protein can induce neural stem cells to differentiate into AChE positive neurons.

Objective To investigate the relationship between tumor necrosis factor-alpha (TNF-α) and development of chronic obstructive pulmonary disease (COPD).Methods COPD patients and controls were divided into three groups: COPD group (n=66), smoker control group (n=42) and health control group (n=23). COPD group was further divided into the serious group (n=23) and non-serious group (n=43). The concentration of TNF-α of all cases was detected by human Th1/Th2 cytokine kit.Results The concentration of TNF-α in the COPD group was significantly higher than that of the smoker and healthy groups ( P<0.01). Furthermore, compared to non-serious COPD group, the concentration of TNF-α was higher in the serious COPD group ( P<0.05).Conclusion The concentration of TNF-α might be related with the pathogenesis and development of COPD.

Objective To investigate the effect of extracellular signal-regulated kinases(ERK) signal transduction in the process of NSCs differentiating into neurons in the fimbria-transected hippocampi's extracts. Methods Twelve Sprague-Dawley rats'right fimbrias were transected. The extracts were gained from the fimbria-transected hippocampi at the 14th day normal rat, and the extracts supernatant fluid was collected after centrifugal process, then the protein concentration in the extracts was determined. In the serum-free medium,NSCs from the fetal hippocampus were planted on 24 well culture plate, then were divided into three group and eight wells for each group as follows: the transected group contained the extracts of the fimbria-transected hippocampi;the normal group contained the extracts of the normal hippocampi;the pure control group have no extracts. After cultured for 14 days,the cells were detected by using MAP-2 and p-ERK immunofluorescence. Result The number, area, perimeter of MAP-2 positive neurons were all declined in transected group, the normal group and the control group orderly. Statistic results showed significant difference between every two groups. The number of MAP-2/p-ERK double-positive neurons were decreased in transected group, the normal group and the control group orderly, but the percentage of double-labeled neurons in total MAP-2 positive neurons were increased in turn. In these two aspect, there were also significant difference between every two group. And most of the MAP-2/p-ERK double-positive neurons were immature. Conclusion The extracts of the fimbria-transected hippocampi had obvious effects on promoting NSCs differentiating into neurons and speeding up the maturation of neurons than those of the normal hippocampi. The morphological results showed that ERK signal transduction might be related to the differentiation of NSCs into neurons.

Objective Modified the medium that can increase single\|clone formed rate and confirmed the single clone spheres had the multipotential of differentation. Methods We modified the medium, that is, the medium contained half of primary culture medium and half of fresh culture medium. A great deal of neurospheres dervied from a single cell were plated averagely into 24 well plates and added into the DMEM differentiation medium (containing serum). After culturing for 14 days, cultures were stained with the neuronal\| ang glial\|specific markers (MAP\|2 for neurons, GFAP for astrocytes and CNP for oligodendrocytes). Results Each 96 well plate containing half of primary culture medium generated two to three single clone spheres, in control plate containing only fresh medium generated half to one single clone sphere. After differentiation, these cell clones expressed MAP\|2, GFAP and CNP positive respectively.Conclusion\ Using half of primary culture medium can increase single\|clone formed rate and these cell clones had the multipotential of differentiation.\;[

Objective To evaluate the effects of ginkgolide B on inducing neural stem cells differentiating into neurons. Methods A great deal of single cell clone neurospheres raised from single cell and proliferated by the technology of serum\|free culture and single cell clone.Suspensions of cell clone neurospheres were plated equably into 24 well plates and added into the 10% FBS differentiation medium containing ginkgolide B,BDNF or without any factor.Cultures were terminated at 7 and 14 days respectively.MAP\|2,neuron\|specific marker,were used to mark neurons by immunofluorescence.MAP\|2 positive neurons were observed and counted by fluorescence microscope.The area and perimeter of these positive neurons were analyzed. Results The number of MAP\|2 positive neurons in ginkgolide B group is more than that in the control group in two periods.The area and perimeter of MAP\|2 positive neurons in ginkgolide B group were markedly larger than those in the control group at 7 and 14 days after cultured,but it's less than those in the BDNF group.Conclusion\ Neural stem cells can be induced to differentiate into neurons by ginkgolide B which has the similar role to BDNF.\;[

It is an important teaching task how to make respiratory disease specialists to accept the standardization training of pulmonary function. However, the theory of pulmonary function is comparatively abstract and the training time is short, but the task is heavy. In order to explore a set of feasible training mode, the pulmonary function laboratory of Zhongshan Hospital affiliated to Fudan University carries out various forms of training, such as compiling textbooks, establishing case database, using multimedia teach-ing, arranging one-to-one guided teaching, and training the ability of doctor-patient communication.
