Objective To discuss X-ray, CT and MR findings of primary bone lymphoma. Methods The X-ray, CT and MR findings of 6 cases with non-Hodgkin lymphoma of bone proved pathologically were retrospectively analysed.Results The average age of 6 cases was 51 years old and the lesions all localized at long bone(especially the metadiaphysis) and pelvis. Imaging findings included: osteolytic or moth-eaten bone destruction,surrounding soft tissue mass formation which generally exceeded the extents of bony changes, the cortex bone was destructed and discontinuity.Conclusion primary bone lymphoma has prevalent age and certain imaging specificity.

OBJECTIVETo explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.

METHODSFifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.

RESULTS(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).

CONCLUSIONThere is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.

METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.

RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).

CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.

OBJECTIVETo investigate the expression of vitamin D3 upregulated protein-1 (VDUP1) in peripheral eosinophils at different stages of asthma and its correlation with clinical manifestations of asthma.

METHODSFourteen normal volunteers and 51 mild to moderate asthma patients, including 16 untreated patients with asthma attack and 35 with asthma remission by continuously corticosterone inhalation. The symptom severity and pulmonary function indices were evaluated and induced sputum eosinophil counts and blood eosinophil count measured. VDUP1 and beta-actin gene fragments were amplified simultaneously by RT-PCR from the total RNA of peripheral eosinophils, and 10 microl of the RT-PCR product underwent agarose gel electrophoresis and the VDUP1/beta-actin ratio was obtained by Gel-Pro software.

RESULTSVDUP1/beta-actin ratio significantly decreased in untreated patients with asthma attacks in comparison with normal volunteers (0.314+/-0.242 vs 0.532 +/-0.279) but not in patients with asthma remission (0.612+/-0.381). In the former patients, a positive correlation of VDUP1/beta-actin ratio was found with FEV1.0% (r=0.587, P=0.046) and %PEF (r=0.563, P=0.033), whereas an inverse one observed with sputum eosinophil count (r=-0.436, P=0.049).

CONCLUSIONVDUP1 expression in the eosinophils correlates to eosinophil activation and may influence the disease severity of asthma patients.

Objective:Our previous study demonstrated serum leptin in patients with systemic lupus erythematosus(SLE) ac-celerated the senescence of mesenchymal stem cells (MSC),the aim of this study is to observe the effects of leptin-treated MSC on immune cells.Methods:Umbilical cord derived MSCs were isolated,and peripheral blood mononuclear cells (PBMC) in SLE patients were obtained by density gradient centrifugation with Ficoll.Three groups were divided,PBMC only,the co-culture of PBMC and MSC treated with or without leptin (100 ng/ml).The frequencies of immune cells were detected by flow cytometry,including CD4+CD25+Foxp3+regulatory T (Treg) cells,CD4+IL-17+Th17 cells,CD4+CXCR5+PD-1+T follicular helper (Tfh) cells,and CD19+B cells.Results:The frequency of regulatory T cells was lower in leptin-treated MSC group,compared with MSC group.The frequency of Th17 cells was increased by MSC pretreated with leptin.The frequency of Tfh cells was elevated by leptin-treated MSC compared with MSC control,but there was no statistical significance.MSC pretreated with leptin also restored the activation of T cells evaluated by CD25 and CD69,compared with untreated MSC.In addition,leptin-treated MSC increased the median fluorescence intensity of CD25, but not CD69 on B cells.Conclusion:Leptin not only accelerated cell senescence of MSC in vitro,but also impaired the capacity of MSC modulating the immune cells.
