Objective To investigate the clinical presentation, morphological features, immunohistochemical staining of the gastrointestinal stromal tumor (GIST), and its histogenesis as well. Methods The morphologic characteristics of GISTs were studied in 58 cases using light microscopy. The expression of c-kit(CD117), CD34 and vimentin were detected in all of the cases with EnVision staining. Results Among 58 cases of GISTs, 41 were spindle cell type, 5 epithelioid cell type and 12 mixture type, equivalent to 86.6 %(58 of 67) of all of the mesenchymal tumors of gastrointestinal tract admitted in the same period. The epithelioid cell type tumors were mainly composed of the epitheloid cells, predominantly short spindle, oval or round in pattern, with an overall eosinophilic cytoplasm by hematoxylin-eosin stain. Focal cytoplasmic vacuolization was often seen. Sometimes signet-ring like cells and cells with a clear cytoplasm were seen in the epithelioid stromal tumor. The tumor cells arranged in interlacing fascicles forming whorls or sometimes cell clusters. All of the 58 stromal tumors were strongly positive for vimentin (100 %), 55 out of 58 tumors positive for CD117 (94.8 %) and 46 out of 58 positive for CD34(79.3 %). Some cases also expressed SMA, actin, S-100 and MBP. Conclusions GISTs were the most common mesenchymal tumor seen in the gastrointestinal tract. Under light microscope, the morphology of stromal tumors sometimes looks like a leiomyoma or Schwannoma. The application of immunohistochemical markers (particularly CD117 and CD34) is considered necessary for the differential diagnosis. GISTs may originate from the pluripotential precursor cells like the interstitial cells of Cajal.

Objective:To study the neuroprotective effect of nobiletin on the symptoms of postoperative cognitive impairment (POCD) induced by sevoflurane inhalation.Methods:Twenty-four aged SD rats (12 female mice and 12 male mice) were divided into three groups randomly: control group ( n=8), surgery group ( n=8) and surgery + nobiletin group ( n=8), with 4 females and 4 males in each group.The rats in surgery group and surgery+ nobiletin group were given normal saline(0.1 ml/10 g, once a day) and nobiletin(100 mg/kg, once a day) intragastrically for 6 weeks.Then the rats were anesthetized by sevoflurane and treated by abdominal exploration surgery, and then continued gavage for 1 week.The rats in control group were given normal saline(0.1 ml/10 g, once a day) intragastrically for 7 weeks without anesthesia or surgery.Sevoflurane inhalation anesthesia and abbreviated laparotomy were not done for control group.Morris water maze and open field experiment were used to measure the memory and cognitive ability and the independent exploration ability respectively.The changes of α-band electroencephalogram (EEG) were recorded by multi-channel physiological signal acquisition and processing system.The concentration of S100β, a marker of neurological impairment was detected by ELISA.Western blot was used to detect the expression level of IBA-1 in microglia.SPSS 20.0 software was used to analyze the data. Results:There were no significant differences in Morris water maze, positioning cruise test and open field test among the groups before operation (all P>0.05). The differences were statistically significant among the groups 7 days after operation (all P<0.05). Compared with the control group (the escape latency, path length and cross platform times were ((20.37±1.11)s, (552.37±14.19)cm, (6.75±0.43)times respectively), the escape latency ((40.87±2.03)s) and path length ((1 258.62±19.53)cm) of rats in surgery group were significantly longer (both P<0.01), and the cross platform times ((2.12±0.33)times) significantly reduced ( P<0.01). The differences between surgery + nobiletin group ((22.37±1.11)s, (584.50±10.90)cm, (6.62±0.48)times) and control group were not significant (all P>0.05). The open field experiment showed that the movement distance, the crossed square number, and activity times in surgery group ((1.78±0.55) m, (4.75±0.50), (14.87±0.33) times) decreased significantly compared with those in control group ((3.73±0.07) m, (11.10±0.78), (51.12±0.78) times, all P<0.01). No significant difference was found between surgery + nobiletin group ((3.76±0.07)m, (10.75±0.66), (50.75±0.43)times) and control group(all P>0.05). Before anesthesia, there was no significant difference in the power ratio of α-band among the three groups ( P>0.05), but the differences during anesthesia and operation were significant ( F=72.58, 101.50, P<0.01). During anesthesia and operation, the power ratio of α-band in anesthesia and in surgery group (2.51±0.04, 2.14±0.03) were significantly lower (both P<0.01) than those in control group (3.49±0.03, 3.49±0.03), while there was no obvious changes (both P>0.05) in the surgery + nobiletin group (3.50±0.04, 3.51±0.04). There were significant differences in Bcl-2 protein expression and caspase 3/7 protein activity among the three groups ( F=5.21, 7.84, P<0.01). Compared with control group (1.00±0.02, 1 557.46±3.63), Bcl-2 of rats in the surgery group(0.40±0.05) were significantly lower and Caspase3/7 expression of surgery group (3 689.58±10.46) was significantly higher (both P<0.01), while the rats in the surgery + nobiletin group had no significant difference in both Bcl-2 level (1.03±0.06) and caspase 3/7 activities (1 805.28±6.17, both P>0.05). The difference of S100 β protein expression was significant among the three groups ( F=490.80, P<0.01). Compared with the control group ((0.18±0.01)μg/L), the concentration of S100β protein in the surgery group ((2.13±0.02)μg/L) decreased ( P<0.01), while there was no significant difference in the surgery + nobiletin group ((0.16±0.01) μg/L, P>0.05). The expression levels of IBA-1 protein ( F=10.83) and TNF-α, IL-1, IL-1β and IL-6 ( F=996.20, 221.40, 73.02, 174.13) were significantly different among the three groups (all P<0.01). The expression level of the neuroglial marker IBA-1 in the surgery group(1.36±0.02) was significantly higher than that in the control group (1.00±0.01, P<0.01), while the surgery + nobiletin group (1.03±0.01) had no significant different compared with control group ( P>0.05). The levels of inflammatory factors, including TNF-α, IL-1, IL-1β and IL-6, in the brain of rats treated with nobiletin ((49.06±3.63)pg/mg, (2.09±0.43)pg/mg, (16.27±0.80)pg/mg, (2.11±0.19)pg/mg) were significantly lower than those in the surgery group((145.10±6.46)pg/mg, (5.67±0.43)pg/mg, (27.88±3.43)pg/mg, (4.74±0.32)pg/mg, all P<0.01). Conclusion:Nobiletin can obviously alleviate POCD symptoms caused by sevoflurane inhalation anesthesia.

Objective To explore the differences of the proliferation ability and the antineoplastic activity of CIK cells against origenal hepatocellullar cancer cells between healthy adults and tumor patients in vitro. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors and tumor patients were incubated to induce CIK cells in the presence of interferon gamroa(IFN-γ) ,IL-2 and anti-CD3 monoclonal antibody (mAb). The changes in the proliferation activity and phenotypes of the CIK cells were identified by flow cytometric analysis. Single cell suspension was prepared bom the fresh hepatocellular carcinoma tissue by using mechanical trituration method. MTT assays were used to determine the cytotoxicity of CIK cells against origenal hepatocellullar cancer cells. Results The CIK cells from both healthy donors and tumor patients were significantly increased with the extension of time. The expression rate of CD3+/CD56+ cells from healthy donors rose from 1.053% ±0.22% on 1st day ,25.36% ±2.19% on the 7th day to 55.12% ±1.99% on the 14th day ,which was significantly higher than that of tumor patients ( P ＜ 0.05). MTT assays showed that the cytotoxicity of CIK cells from both enhanced obviously with the addition of Effect/Target rate and extension of time(P ＜0.05). After the origenal hepatocellullar cancer cells were treated by CIK cells 24 hours, the cytotoxicity of CIK cells from healthy donors at the effector:target ratio of 10 ∶ 1,20 ∶1 and 40 ∶1 was significantly higher than that of tumor patients(P＜0.05) ,respectively. After treated 48 hours, compared with tumor patients, the cytotoxicity of healthy donors? CIK at the three effector:target ratio was alsosignificantly higher(P ＜0.05), respectively. Conclusion CIK cells from both have amplification ability and cytotoxic activity in vitro,and the proliferation ability and killing activity of healthy adults CIK is stronger than that of tumor patients,which provides an experimental basis for CIK to clinical application as an adoptive immunotherapy.
