Objective:To introduce recent progress on diagnosis and treatment of benign symmetric lipomatosis(BSL).Method:Detailed clinical data of 6 patients with BSL were reviewed and analyzed.We present a summary of the clinical symptoms,physical sign,diagnosis and therapeutic methods of BSL. And related literatures were discussed together.Result:All of 6 patients have excessive subcutaneous fat deposit predominantly around neck.One patients had upper extremity localizations. Six patients had the complication of left ventricular diastolic function changes,glucose intolerance or diabetes mellitus, chronic hepatopathy, hyperuricemia and sleep apnea syndrome in one or more. One patients with several symptoms occur simultaneously, another one female patient was accompanied by all symptoms but chronic hepatopathy. Five male patient were alcohol abusers. Tatal neck lipentomy and abstinence from alcohol were performed on 5 patients. One patient refused treatment.During a follow-up of 3 months to 4 years, one patients was relapsed again,and no recurrence was seen in another 4 patients. All pathological results were nonencapsulated fat. Conclusion:BSL is a lipodystrophy caused by diffuse fatty tissue, symmetry deposition in the neck and shoulder subcutaneous fascia space or deep fascial space .The highest incidence favors to middle-aged man who is alcoholist. Chronic alcohol addiction and typical clinical symptoms help to diagnosis BSL. Lipectomy represents a successful procedure in treating BSL.

Objective To investigate the effects of ischemic preconditioning (IP) on the expression of extracellular signal-regulated protein kinase (ERK) and c-jun N-terminal kinase (JNK) in hippocampus in a gerbil model of ischemia-reperfusion (I/R) injury and the role of ERK and JNK in the mechanism of ischemic cerebral preconditioning. Methods Gerbils of both sexes weighing 50-70kg were randomly divided into 4 groups : ( Ⅰ ) sham operation group; ( Ⅱ ) IP group; (Ⅲ) I/R group and ( Ⅳ ) IP + I/R group. Cerebral ischemia was produced by occlusion of bilateral common carotid arteries and confirmed by isoelectricity on EEG. In sham operation group bilateral common carotid arteries were exposed but not occluded. In IP and I/R groups the animals were subjected to 3 min (IP group) or 5 min (I/R group) cerebral ischemia respectively. In IP + I/R group the animals first underwent 3 min cerebral ischemia followed by 24h reperfusion and then were again subjected to 5 min cerebral ischemia. Open field test was performed to evaluate the behavioral deficit 1,3,5 and 7 days after ischemia. The animals were sacrificed at 15 min, 2, 4, 6h and 1, 3, 5, 7 days after ischemia. The brains were immediately removed for detection of apoptosis (TUNEL) and expression of p-ERK and JNK (immuno-histochemistry) in hippocampal CA1 and CA3 regions and microscopic examination. Results Compared with I/R group the behavioral deficit was significantly decreased and the number of living pyramidal neurons was significantly increased and apoptotic neurons significantly decreased in IP + I/R group. No p-ERK expression was detected in CA1 region in all of the 4 groups but in CA3 region the p-ERK expression was significantly higher in group IP + I/R than in group I/R. The p-JNK expression increased gradually during reperfusion in both CA1 and CA3 regions and was still detectable 7 days after ischemia and was significantly lower in CA1 region in group IP + I/R than in group I/R.Conclusion IP protects hippocampal neurons from I/R injury by inhibiting the expression of p-JNK in CA1 region and enhancing the activity of p-ERK in CA3 region

Endoplasmic reticulum (ER) stress occurs in macrophage-rich areas of advanced atherosclerotic lesions and contributes to macrophage apoptosis and subsequent plaque necrosis. The purpose of the present study was to investigate the effects of caveolin-1 (Cav-1) on ER stress-induced apoptosis in cultured macrophages and the underlying mechanisms. RAW264.7 cells were incubated with thapsigargin (TG) to establish ER stress model. And Cav-1 expression was detected by Western blot. After being pretreated with filipin(III), a caveolae inhibitor, RAW264.7 cells were assayed with flow cytometry and confocal laser scanning microscopy to detect cell apoptosis. Moreover, p38 mitogen-activated protein kinase (MAPK) phosphorylation and C/EBP homologous protein (CHOP) expression were detected with Western blot. The results showed that Cav-1 expression was markedly increased at early stage of TG treatment (P < 0.05) and then decreased with prolonged or high dose TG treatments. The increasing of Cav-1 expression induced by TG in RAW264.7 cells was abolished under inhibition of caveolae by filipin(III) (P < 0.05). The effect of TG on apoptosis of RAW264.7 cells was further augmented after pretreatment with filipin(III) (P < 0.05). Western blotting showed that MAPK phosphorylation induced by TG was inhibited by filipin(III) in RAW264.7 cells (P < 0.05), whereas CHOP remained unchanged (P > 0.05). These results suggest that Cav-1 may play a critical role in suppressing ER stress-induced macrophages apoptosis in vitro, and one of the mechanisms may be correlated with the activation of p38 MAPK prosurvival pathway.

OBJECTIVETo investigate the roles of telomere and telomerase in the effect of ginsenoside Rg1 to delay hematopoietic stem cell senescence.
METHODSca-1(+) HSC was isolated by magnetic cell sorting(MACS) and divided into five groups: the control group, the aged model group, the Rg1 group, the Rg1 treated aged group and the Rg1 delayed aged group. The changes of cells were observed by senescence-associated beta-Galactosidase (SA-beta-Gal) staining. Cell cycle assay and culture of mixed hematopoietic progenitor cell were used to investigate the effect of ginsenoside Rg1 to delay Sca-1(+) HSC senescence. Telomere length and telomerase activity were detected by southern blotting and TRAP-PCR-SYBR Green staining.
RESULTCompared with aged model group, the percentage of positive cells expressed SA-beta-Gal and the number of cells entered G1 phase were decreased and the number of colony of mixed hematopoietic progenitor was increased. It showed markedly decreased in the shortening of telomere length and reinforcing in the telomerase activity to Rg1 treated aged group and Rg1 delayed aged group. The change of Rg1 delayed aged group was significantly higher than Rg1 treated aged group.
CONCLUSIONActivation of telomerase and prolonging of telomere length might be involved in the process of ginsenoside Rg1 to delay and treat the senescence of Sca-1(+) HSC.

OBJECTIVETo study the proto-oncogene RON mediated aggression of Raji cells and the inhibitory effects by monoclonal antibody Zt/f2 (2f2).
METHODSThe effects of RON ligand macrophage stimulating protein (MSP) (2.0 nmol/L) and inhibitory Zt/f2 (2F2) (2.0 nmol/L) antibody on proliferation of RON positive Raji cells after treatment for 24 and72 hours were detected by MTT method, colony formation units (CFU) of Raji cells by methylcellulose semi solid culture, Raji cells apoptosis and cell cycle analysis by AnnexinV/PI double staining, expression of RON, apoptosis-related proteins, and cyclins by Western blot.
RESULTS(1)Compared with the cell viability (1.0) and counts of CFU (103.6±7.0) in control group, Raji cells after MSP treatment had better viability (1.35±0.20) and CFU counts (133.7±10.4) (P<0.05), but worse viability (0.68±0.11) and CFU counts (66.3±6.1) after Zt/f2 (2F2) treatment (P<0.05). (2)Percentage of Raji cells apoptosis after Zt/f2 (2F2) antibody treatment (12.16±2.33)% was significantly increased than the control (2.89±1.03)% (P<0.05). The percentage of Raji cells arrested in G0/G1 phase was increased after Zt/f2 (2F2) antibody treatment as compared to the control [ (54.96 ±3.70)% vs (39.10±2.30)%, (P<0.05) ]. (3) High-level of RON phosphorylation and β-catenin expression activated by MSP could be inhibited significantly by Zt/f2 (2F2), which also up-regulated the expression of caspase-3, caspase-8, caspase-9 and PARP and down-regulated anti-apoptotic MCL-1 gene and inhibitor of apoptosis protein XIAP expression, accompanied with G1 phase protein changes accordingly.
CONCLUSIONMSP could aggravate Raji cells proliferation. Inversely, Zt/f2 (2F2) could inhibit proliferation and induce apoptosis by inhibition of RON phosphorylation and up-regulation of apoptosis related proteins.

OBJECTIVETo study the effects of sinomenine (Sin) on cell proliferation, intracellular expression of cyclooxygenase-2 (COX-2), and production of PGE2 in lipopolysaccharide-induced PC-12 cells, To explore the Sin's mechanism on nerve cell.
METHODPC-12 cells were cultured with nerve growing factors (NGF), and pretreated with Sin at various concentrations (0, 3 x 10(-6), 30 x 10(-6), 150 x 10(-6) mol x L(-1)) for 2 hours, then with or without stimulation of lipopolysaccharide (LPS). The proliferation activity of PC-12 cells was determined by 3H-TdR incorporation, and the production of PGE2 in culture supernatants of PC-12 cells was detected with competitive ELISA. Expression of COX-2 mRNA in PC-12 cells was analyzed by semi-quantitative RT-PCR, and expression of COX-2 protein was estimated by Western blot method and cellular enzyme immunoassay. Nuclear factor-kappa B (NF-kappaB) activity in whole-cell extract of PC-12 cells was also measured by an ELISA-based method.
RESULTThe data showed that Sin down-regulated the expression of COX-2 mRNA and protein, and reduced the production of PGE2 in the LPS-stimulated PC-12 cells which correlated with Sin's concentrations positively. In addition, NF-kappaB activity in LPS-stimulated cells was suppressed significantly by Sin. No inhibition of proliferation of PC-12 cells due to Sin treatment was observed.
CONCLUSIONSin mediates the down-regulation of expression of COX-2 and production of induced PGE2 in PC-12 cells by suppressing the activity of NF-kappaB.
