Objective To study the pain controlling effects of non-pharmaceutical interventions in neonatal intensive care unit (NICU) setting. Methods Infants who received radial artery puncture were assigned into control group, non-nutritive sucking (NNS) group and NNS plus glucose (NNS + GS) group according to their admission sequences. Each group contained 20 patients. Heart rate ( HR), respiratory rate (RR) and oxygen saturation (SpO2 ) before and after the procedure were monitored using Multi-Parameter Monitor ECG. Neonatal pain was evaluated using the preterm infant pain profile (PIPP). Results Among all three groups, after radial artery puncture, HR and RR were significantly increased, and SpO2 was significantly decreased (P < 0. 01). HR, RR and SpO2 variations in NNS group and NNS + GS group were less significant than the control group (P < 0. 05), and recovered to baseline more quickly. During the radial artery puncture, PIPP scores of infants in NNS and NNS + GS group were significantly lower than the control group (P < 0. 01), with NNS + GS group lower than NNS group (P <0. 05). Conclusions HR, RR and SpO2 can be used as physiological indicators of neonatal pain. PIPP score is simple and practical to be used in NICU setting. Both NNS and NNS + GS can partially relieve neonatal pain, and NNS + GS works better.

Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P＜0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P＜0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P＞0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P＜0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P＞0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

Objective To study the expression and significance of Th17 cells from peripheral blood of patients with rheumatoid arthritis (RA). Methods Intracelluar flow cytomete detection of IL-17/IFN-γ and IL-17/IL-6 was established using anti-CD3/Anti-CD28/IL-23 as stimulators after isolation of untouched human CD4~+T cells from PBMC. There were three groups in the present study: ①healthy controls group; ② RA stable group; ③RA active group. Results The isolation of untouched human CD4~+T cells from PBMC was effective and its purity was over 90%. The percentage of intracelluar IL-17 in CD4~+ T cells from RA patients was increased significantly. Such percentage in active group (1.54±0.41) was higher than that of stable group (0.70±0.21, P<0.01) and both of them were higher than those of healthy controls (0.42±0.12, P<0.01). Under anti-CD3/Anti-CD28/IL-23 stimulation, the percentage of intracelluar IL-17 was also increased significantly(P<0.01). The porcentage of intracellular IFN-γ was similar to that of IL-17, while that of IL-6 was not significantly different. There is an correlation between IL-17 and IFN-γ or IL-6. Conclusion There is an abnormal expression of IL-17 and IFN-γ in human CD4~+T cells in RA patients, which is related to disease activity . Th17 cells may be used as a new marker for the assessment of RA activity.

Objective: To assess the accuracy and application value of type III portable monitor (III PM) of sleep apnea (SA) for in-hospital patients with cardiovascular disease (CVD). Methods: A total of 101 CVD patients received sleep apnea monitoring by both type II polysomnography ( II PSG) and III PM were enrolled to compare the apnea-hypopnea index (AHI) measured by 2 instruments. AHI was assigned into 4 grades: Normal (AHI<5), Mild grade (5≤AHI<15), Moderate grade (15≤AHI<30) and Severe grade (AHI≥30). Kendall correlation coefficient and Kappa value were calculated, pair wise t test was conducted in relevant patients. Results: II PSG and III PM measured AHI were (18.0±16.6) events/h and (18.6±17.4) events/h, P>0.05. Kendall correlation coefficient for 4 AHI grades was 0.701, P<0.01 which assumed strong correlation; Kappa value of consistency was 0.493, P<0.01 which assumed medium strong correlation. Using AHI≥15 as cut-off point, Kappa coefficient for the consistency between II PSG and III PM was 0.679, P<0.05, which meant high consistency. Taking II PSG as standard and AHI≥15 as cut-off point, the AUC of III PM measured AHI was 0.918 with the specificity at 80.4% and sensitivity at 87.3%. The best diagnosing cut-off value of III PM was AHI=15.70, at this point, the maximum Youden's index was obtained as 0.695. Conclusion: Using AHI≥15 as standard, III PM and II PSG had the favorable consistency and accuracy for monitoring the severity of SA for in-hospital patients with cardiovascular disease. AHI=15.7 was the best cut-off point of III PM in diagnosing moderate and severe SA in relevant patients.

Objective To study the expression of IL-17, RORγt in CD4+T cells from patients with ankylosing spondylitis (AS). Methods The specimens of venous blood PBMC were collected from 28 patients with AS and 15 healthy subjects. Intracellular flow cytometry detection of IL-17 was established after isolation of human CD4+ T cells from PBMC. The expression level of IL-17, RORγt mRNA in CD4+ T cells was determined from 28 AS patients and 15 healthy controls by real-time fluorescence quantitative RT-PCR using Anti -CD3/Anti -CD28 as stimulators or not. Analysis of variance and Pearson correlation were selected. Results The isolation of human CD4+ T cells from PBMC was effective and its purity reached 90%. The percentage of intracellular IL-17 in CD4+ T cells from AS pati-ents in the AS active group was higher than that of the AS stable group and healthy control group (P<0.01). The expression level of IL-17, RORγt mRNA in CD4+ T cells was significantly higher in patients with AS than in controls. After stimulated with anti-CD3/ anti-CD28 stimulation, the percentage of IL-17, RORγt mRNA was increased significantly (P<0.01). The percentage of IL-17, RORγt mRNA in the 12 h group was higher than that of the 24 h group, while both of them were higher than those without stimulation (P<0.05). Conclusion There is an abnormal expression of IL-17, RORγt in human CD4+ T cells from AS patients. Our results indicate that the abnormal expression of IL-17 might play a role in the development and progression of AS.

OBJECTIVETo study the immunophenotype and gene rearrangement pattern of pulmonary lymphomatoid granulomatosis.

METHODSNine cases of pulmonary lymphomatoid granulomatosis, included 5 cases of open lung biopsy, 3 cases of lobectomy specimen and 1 case of autopsy, were retrospectively analyzed by immunohistochemistry, in-situ hybridization for Epstein-Barr virus-encoded RNA, immunoglobulin and T-cell receptor gene rearrangement studies.

RESULTSThe age of patients ranged from 3 to 59 years. The male-to-female ratio was 3: 6. Histologically, all cases showed lymphocytic infiltration surrounding the blood vessels and in the perivascular areas. Most of these lymphoid cells expressed T-cell marker CD3. There were also variable numbers of CD20-positive B cells. The staining for CD56 was negative. According to the WHO classification, there were 4 cases of grade I , 1 case of grade II and 4 cases of grade III lesions. Six cases had gene rearrangement studies performed and 3 of them demonstrated clonal immunoglobulin gene rearrangement (including 1 of the grade II and 2 of the grade III lesions). No T-cell receptor gene rearrangement was detected.

CONCLUSIONSPulmonary lymphomatoid granulomatosis may represent a heterogeneous group of lymphoproliferative disorders. Some of the cases show B-cell immunophenotype and clonal immunoglobulin gene rearrangement, especially the grade II and grade lesions. They are likely of lymphomatous nature.

OBJECTIVETo investigate the effect of acupuncture serum on Ca2+ content in the cultured nervous cells of hippocampus after ischemia-reperfusion, so as to probe into humoral factors in acupuncture treatment.

METHODSThe neurons of the hippocampus from the new born rats were cultured for 9-11 days. Fluorescein-molecular probe Fluo-3 AM was used for staining of intracellular Ca2+. Fluorescent levels in the nervous cells cultured with the serum of the normal rats or the rats given electroacupuncture at "Baihui" (GV 20), "Zusanli" (ST 36), "Quchi" (LI 11) and "Sanyinjiao" (SP 6) for 2 weeks were determined by using a laser confocal microscope.

RESULTSAfter the normal serum was added, the intracellular Ca2+ fluorescent levels increased to 697 +/- 113 from 461 +/- 96, while after acupuncture serum was added, the Ca2+ fluorescent levels decreased to 584 +/- 103 from 673 +/- 108, indicating that after addition of acupuncture serum, the increased intracellular Ca2+ content could be decreased.

CONCLUSIONThere are some active substances in acupuncture serum which can obviously decrease intracellular Ca2+ content after ischemia-reperfusion, so as to provide a direct evidence for role of humoral factor in acupuncture treatment.
