目的 对晚期非小细胞肺癌(NSCLC)患者进行回顾性分析,探讨参一胶囊维持治疗对患者炎症因子的影响。方法 经参一胶囊联合化疗一线治疗后取得缓解或稳定的37名晚期NSCLC患者意向性分为治疗组(A组,21人)和对照组(B组,16人)。A组继续服用参一胶囊每天2次,每次20 mg,服药至疾病进展或无法耐受;B组未予特殊治疗。分别于第1 d、90 d采血,检测白细胞计数、中性粒细胞计数、C反应蛋白、肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)、白细胞介素1α(IL-1α)、白细胞介素6(IL-6)和白细胞介素10(IL-10)。结果 治疗前后比较,治疗组各项炎症指标均未发生明显变化(P>0.05);而对照组的TNF-α、IL-1β、IL-6上升(P值分别为<0.001、0.032、0.001),IL-10下降(P=0.035);治疗后两组间比较,对照组TNF-α、IL-1β、IL-6上升(P值分别为<0.001、0.001、0.004),IL-10则下降(P=0.002)。两组间IL-1α及白细胞计数、中性粒细胞计数、C反应蛋白无变化(P>0.05)。结论 参一胶囊维持治疗可使晚期NSCLC患者TNF-α、IL-1β及IL-6的低表达,提示调节炎症反应可能是参一胶囊维持治疗抑制NSCLC进展的机制之一。

Objective To retrospectively investigate the influence of Shenyi Capsule maintenance therapy on inflammatory factors in patients with advanced NSCLC. Methods Thirty seven patients with advanced NSCLC, who had become palliative or stable after first-line treatment with combined Shenyi capsule chemotherapy, were intentionally assigned to treatment group (group A, 21 patients) and control group (group B, 16 patients). Shenyi capsule was given to group A (20mg p.o., bid) until appearance of deterioration or intolerance, while no special treatment was given to group B. Leukocytes, neutrophils, C-reactive protein, tumor necrosis factor α (TNF-α), interleukin-1β(IL-1β), interleukin-1α (IL-1α),interleukin-6(IL-6) and interleukin-10(IL-10) were tested by blood specimens taken respectively on 1st day and 90th day. Results There were no statistical differences (P>0.05) between the level of inflammatory factors on 1th day and 90th day in treatment group. In control group, however, TNF-α、IL-1β and IL-6 increased (P<0.001, P=0.032、P=0.001 respectively) and IL-10 decreased significantly (P=0.035). Furthermore, the level of TNF-α、IL-1β and IL-6 in treatment group were also higher (P<0.001, P=0.001, P=0.004 respectively), while IL-10 was lower (P=0.002)than control group on 90th day. There were no statistical differences(P>0.05)between the two groups in the level of IL-1α, leukocyte, neutrophils or C reactive protein on 1th day and 90th day. Conclusion Shenyicapsule maintenance therapy could lower the expression of TNF-α、IL-1β and IL-6 in patients with advanced NSCLC, which indicates that the regulation of inflammatory reaction may be one of the mechanisms of inhibition from NSCLC progression in Shenyi capsule maintenance therapy.

目的 探索内源性神经干细胞在大鼠海马可溶性因子中的体外发育归宿及分化鉴定。方法 显微镜下分离Wistar大鼠海马组织放置于低温DMEM/12培养基,低温振荡2小时后高速离心(15000 g),获取实验所用海马组织可溶性因子。取材出生1天的Wistar乳鼠海马中的内源性神经干细胞(endogenous neural stem cells, ENSCs),将ENSCs分别于含海马可溶性因子终浓度为0(对照组)、50、100、200、400 μl/mL的无血清DMEM/F12培养基中培养6天并每日观察,使用免疫细胞化学、Western Blot印记技术比较各组ENSCs中Nestin、CD133的表达量;同时计量并比较各组ENSCs成球个数,以探索在模拟颅内微环境情况下,ENSCs发育、归宿及分化。进一步于最适宜的海马可溶性因子终浓度中分化神经球,对分化的细胞行神经元特异性蛋白入(如:β-tubullin III、MAP2)及胶质细胞特异性蛋白(如:GFAP、S100及p75 NGFR)免疫细胞化学检测。结果 大鼠ENSCs在培养基中呈单细胞漂浮生长,球形; ENSCs于海马可溶性因子各实验分组中培养第2天呈细胞球状态,对照组中无细胞球形成(与100 μl/mL组比较,P₁=0.00),100 μl/mL组与对照组比较有统计学意义(P₁=0.00<0.05);至第6天,在100 μl/mL组中的细胞球数量明显多于其余各组(P₁'=P₂'=P₃'=P₄'=0.00)。在免疫细胞化学检测中,100 μl/mL组中细胞球表达干细胞高亲和蛋白Nestin、CD133阳性,Western Blot免疫印迹检测其中Nestin、CD133蛋白高于对照组。进一步分化试验中,细胞球呈贴壁生长的单细胞状态、有突起伸出、长梭形,免疫细胞化学检测分化的细胞表达胶质细胞特异性蛋白GFAP、S100、p75NGFR阳性,但不表达神经元特异性蛋白β-tubullin III与MAP2。结论 大鼠ENSCs在终浓度为100 μl/mL的HSF作用下,可促进 ENSCs的增殖分裂;ENSCs在同样浓度下的HSF中可进一步分化为表达GFAP、S100、p75NGFR阳性的胶质样细胞;100 μl/mL的HSFS是ENSCs的一种生理性诱导剂或参与促进ENSCs增殖、分化及通过细胞替代或因子分泌等机制修复神经损伤。

Objective The aim of this study was to explore induction and differentiation of endogenous neural stem cells(ENSCs) in the hippocampus soluble factors(HSF) from the hippocampus of adult Wistar rats by mimicking an intracranial microenvironment. Methods After Wistar rats sacrificed, the hippocampus tissue was obtained in cold DMEM/F12. After centrigued and filtered, the HSF was stored at -20℃. The ENSCs was obtained from the hippocampus tissue of a neonate Wistar rat. Collected the tissue, digested and obtained the ENSCs. After we observed the morphology, the ENSCs were cultured in different concentration (0、50、100、200、400 μl/mL) of HSF for 6 days, and compared the expression of Nestin and CD133 by immunocytochemistry. Meanwhile,we compared the Nestin and CD133 protein by western blot. And then we explored the optimal concentration of HSF by the numbers of all groups on the second and sixth day. Furthermore, we did the differentiated experiment using the same concentration of HSF. Results The number of neurospheres in the 100 μg/mL group was significantly higher than those in the other groups on the 6th day. Immunofluorescence revealed that the neurospheres from ENSCs in the 100 μg/mL group more highly expressed nestin and CD133 than control. This result was confirmed by western blot analysis. The neurospheres can differentiate into glia-like cells in 100 μg/mL HSF and 1% FBS expressing GFAP, S100 and P75 NGFR by immunofluorescence. Conclusion These data indicated that HSF alone, mimicking a destination of ENSCs in vitro, could induce and differentiate neurospheres from ENSCs, as a new method to get NSCs and glia-like cells differentiated from ENCs to repair the diseases of center nervous system.

Objective To explore quality of life and its risk factors in patients with refractory irritable bowel syndrome(RIBS). Methods 601 IBS patients in gastroenterology clinic and 100 healthy volunteers were invited to complete irritable bowel syndrome- symptom severity scale (IBS-SSS), the Hamilton Rating Scale of Anxiety/ Depression (HAMA/HAMD), Irritable bowel syndrome-quality of life(IBS-QOL). And multiple linear regression analysis was used to explore the determinants of quality of life in patients with RIBS. Results The overall score and subscale scores of IBS-QOL in RIBS group were lower than those in the non-RIBS and healthy group (P<0.05). There were no significant differences in the overall scores of IBS-QOL among different subtypes of RIBS. However, the interference with activities, health anxious, social reaction scores were different among the subtypes (P<0.05). Multiple linear regression analysis demonstrated that quality of life in RIBS was independently associated with the scores in IBS-SSS and HAMA. Conclusion Quality of life in RIBS is obviously decreased. Quality of life in RIBS is closely related to clinical symptoms and anxiety condition.
