Objective To investigate the expression of matrix metalloproteinase-8 (MMP-8) in human breast cancers and its relationship with the clinicopathological parameters,evaluate the relevance of MMP-8 levels to metastases in breast cancer.Methods Human specimens were obtained from 50 patients with invasive ductal carcinomas,and 20 normal breast glands were enrolled.Intact clinical parameters were aviliable for all patients.The protein expression of MMP-8 was determined by immunohistocbemistry technology SP.Results The rate of MMP-8 positive breast cancer was significantly higher than that in normal breast glands [68 ％ (34/50) vs 15 ％ (3/20),P ＜ 0.05].The expression of MMP-8 showed a negative correlation with breast cancer staging.The expression of MMP-8 in stage Ⅰ was higher than that in stage Ⅱ and Ⅲ/Ⅳ[94 ％ (15/16),57 ％ (13/23),55 ％ (6/11),P ＜ 0.05].Lymph node negative patients had a higher MMP-8 expression than patients with lymph node metastases [84 ％ (21/25) vs 50 ％ (13/25),P ＜ 0.05].Conclusion MMP-8 expression is associated with human breast cancer metastases and might be involved in inhibiting metastases.

Objective To observe the effect of neuromuscular electric stimulation (NMES) on post-stroke dysphagia (PSD). Methods Two hundred patients with swallowing dysfunction after stroke were randomly divided into a control group with 67 cases and a study group with 133 cases. All patients received pharmacotherapy and swal-lowing training. The study group also received NMES. The study group was sub-divided into unilateral and bilateral cortical stroke sub-groups, an ischemic stroke sub-group and a hemorrhagic stroke sub-group. The swallowing levels of the groups were compared after 2 courses of treatment with NMES. Results After an average of 20 days of NMES treatment, the level of dysphagia and its severity improved significantly. The patients with dysphagia due to unilateral stroke improved, on average, more than those with bilateral stroke. Patients with dysphagia due to ischemic stroke improved more than those with hemorrhagic stroke. Conclusions NMES therapy combined with rehabilitation train-ing can significantly improve swallowing in patients with PSD.

ADVANCE trial demonstrated that stable intensive glucose control could improve prognosis and the target HbA1c should be 6.5%.While ACCORD and VADT trials suggested aggressive glucose lowering in diabetics at high cardiovascular risk is potentially harmful,tight glucose control yields no significant effect on long duration,poorly controlled patients with complications.DCCT and UKPDS research confirmed benefits of early intensive glucose control could persist due to legacy effect.Steno-2 research showed patients benefit greatly from comprehensive control of risk factors.In sum,early intensive control of risk factors and individualized treatment in diabetics are mainstream therapy.

Objective To investigate the clinical efficacy of fire needling plus moxibustion in treating prurigo nodularis. Methods Ninety patients with prurigo nodularis were randomly allocated to treatment and control groups, 45 cases. The treatment group received fire needling plus moxibustion and the control group, external application of halometasone ointment. Skin lesions and pruritus were scored in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the skin lesion score and the pruritus score in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the skin lesion score and the pruritus score between the treatment and control groups (P<0.01). The total efficacy rate was 81.8% in the treatment group and 60.5% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Fire needling plus moxibustion is an effective way to treat prurigo nodularis.

As a stable marker to reflect the average level of blood glucose,HbA1c is very important in glycaemic control evaluation.However,more and more data from evidence based medicine demonstrated that blood glucose fluctuation can also contribute to diabetic complication and prognosis which can not be neglected.Multiple capillary glucose measurements and continuous glucose monitoring are major methods to detect glucose fluctuation.Apart from insulin,various oral anti-diabetic drugs can reduce postprandial glucose excursion.Representative drugs include ?-glycosidase inhibitors,glinides and short-acting sulfonylureas,each have their own way of acting.

Objective To explore the difference of immunosuppresive effect between the expanded Stro-1+ and Stro-1-subgroups of human mesenchymal stem cells in vitro. Methods Mononuclear cells (MNCs) were isolated from bone marrow (BM) samples and seeded in a T-75 cm2 tissue culture flask contained with Dexter medium. When 50% confluence was obtained, adherent cells were collected and incubated with anti-stro-1 antibody, and the Stro-1+ and Stro-1-MSCs were further seeded for expansion. The total culture time (median) was 15 days. Cells were then analyzed by flow cytometry. One-way mix lymphocyte reaction (MLR) (1?105 responding cells and an equal number of stimulating cells/well were co-cultured in 96-well plates) and nonspecific mitogenic stimuli phytohemagglutinin (PHA) plus interleukin-2 (IL-2) induced lymphocytes proliferation (PBL 1?105/well were mixed with PHA 10?g/ml and IL-2 500U/ml in 96-well culture plates) were established in vitro. 1?103-3?104 irradiated Stro-1+ MSCs and Stro-1-MSCs were added into the two systems at the beginning of reaction. Immunosuppressive actions of both Stro-1+ or Stro-1-MSCs were compared. Results Adherent cells contained a median of 9% (range 5%-26%) Stro-1+ cells, which expressed higher immunophenotype of MSCs. In both reaction systems, suppressive actions occurred in a dose-dependent fashion when whatever Stro-1+ MSC or Stro-1-MSC were added. However, that the addition of 1?103 Stro-1-cells enhanced rather than inhibited the lymphocyte proliferation in one-way MLR. In the presence of various concentrations of MSCs, Stro-1+ MSCs always showed a significantly increased inhibitory effects in comparison to Stro-1-MSCs (P

35), while the expression level of TGF-?1 in Stro-1-MSC was significant higher than that detected in Stro-1+MSC (2-??Ct=0.39, P

Objective:To investigate the clinical characteristics, treatment, and evaluation of the prognosis of syndrome of inap-propriate anti-diuretic hormone (SIADH) in lung-cancer patients. Methods:We review the clinical data of six lung cancer cases, includ-ing four small cell lung cancer, one adenocarcinoma, and one squamous cell carcinoma, with SIADH complication. All six cases were treated in our hospital over the past three years. Results:Patients with various serum sodium levels were provided different therapeutic regimens. Symptoms of fatigue and nervous system disorders, plasma sodium, urine sodium, and plasma osmotic pressure were alleviat-ed. Conclusion:SIADH is a common complication of lung cancer, particularly in small lung cancer cases. Electrolyte disturbances indi-cate poor prognosis, high mortality rate, and delay in treatment because of clinical interest. After a final diagnosis has been made and ap-propriate treatment has been administered, clinical symptoms were relieved and blood sodium levels were quickly and significantly im-proved in these patients.

Objective:To observe the effect of timosaponin AⅢon the proliferation of cultured melanoma B16 and A375 cells and nitrite produced from macrophage activation. Methods:MTT assay was adopted to detect the cell growth inhibition. The morphological changes of B16 and A375 cells were observed under an inverted microscope. Nitrite production of activated mouse macrophages induced by lipopolysaccharide ( LPS) plus IFN-γ was measured by Griess assay. Results: Timosaponin AⅢ could significantly inhibit the growth of B16 cells at the concentration of 16 μmol·L-1 after the 48- and 72-hour treatment, and significantly inhibit the growth of A375 cells at the concentration ranged from 4 to 16 μmol·L-1 after the 48-and 72-hour treatment. Shrinkage, vacuoles and necrosis of B16 and A375 cells were observed after the 48-and 72-hour treatment by 16μmol·L-1 timosaponin AⅢ,the other concentration of timosaponin AⅢ showed no notable effect on B16 cells and vacuoles of A375 cells appeared at the concentration from 4 to 16 μmol· L-1. Compared with RAW 264. 7 stimulated LPS plus IFN-γ,timosaponin AⅢ could significant inhibit nitrite production of macro-phage inflammatory cell model at the concentration of 10μmol·L-1(P<0. 01). Conclusion:Timosaponin AⅢcan inhibit the prolif-eration of melanoma B16 and A375 cells and macrophage inflammation,suggesting it has anti-tumor and anti-inflammatory effects . The anti-tumor effect of timosaponin AⅢ may be related to the inhibition of tumor inflammation.
