Triggering receptors expressed on myeloid cells-2 (TREM-2) is a newly discovered immunoglobulin receptor, which plays an important role in inflammation and immunoreaction. Several recent studies have shown that TREM-2 is aberrantly expressed in various types of cancers such as lung cancer, gastric cancer, liver cancer, colorectal cancer, renal carcinoma and glioma, and it is widely participated in regulating malignant tumor initiation, progression, invasion and metastasis through different signal pathways. TREM-2 is expected to provide evidence for the diagnosis and treatment of malignant tumors.

Objective To study the effects of vascular endothelial growth factor(VEGF) in early stage diabetic retinopathy and their mechanisms,so as to guide the clinical work theoretically.Methods Thirty-six SD rats were randomly divided into four groups.Nine rats were used as normal controls(M Group).Streptozocin were injected intraperitoneally to induce diabetes for 1 month(M1 Group),2 months(M2 Group),and 3 months(M3 group).At the experimental ends of each group,the rats were over anesthetized and their eyeballs were extracted to make digest preparation.Immunofluorescence were used to investigate the expression of VEGF on retinal blood vessels.Transmission electromicroscopy was used to observe the histology of the retinal vessels.Results VEGF immunofluorescence showed an expression rate of 56% in M2 group and 89% in M3 group.Transmission electromicroscopy showed no change in M Group.However,it showed swelling of endothelial cells,finger like process into the capillary cavity,uneven distribution of heterochromatin in pericytes in M1 Group.Obvious fragmental thickening and splitting of basement membrane,swelling and deformation,finger like process to the capillary cavity,and concentration and margination of heterochromatin in endothelial cells,and swelling and deformation of rough surfaced endoplasmic reticulum and mitochondrion in pericytes were observed in M2 and M3 groups,especially in the latter.Conclusion The expression of VEGF proteins in the retinas of diabetic rats increases with the progression of diabetes.It proves that VEGF plays an important role in the occurrence and development of early diabetic retinopathy.

Objective To explore the clinical effectiveness of the platelet parameter in neonatal hypoxic-ischemic encephalopathy(HIE).Methods From Oct,1999 to May 2001,50 cases of neonatal HIE were final diagnosed,the platelet total(PLT),mean platelet volume(MPV) and platelet distribution width(PDW) were dynamic observed.It was compared with 27 cases of normal term infant.Results ⑴PLT in acute period of HIE was obviously lower than that of the normal term infant(P0 05).⑵The PLT in the HIE was decreased(P

The Haemophilus influenzae (Hi) is a common opportunistic pathogen from human respiratory tract. The lower immunity can cause the disease. After the biofilm (BF) is formatted by Hi at the site of infection, the antibiotic sensitivity is declined, which often causes the chronic disease, inducing the difficulty in clinical treatment. In recent years, the pathogenic?ity of Hi BF and BF form related factors have gradually become the focus of clinical and basic research. This paper reviewed recent studies as following.

Objective To explore the abnormal inflammatory cytokine profile of salpingitic infertility by means of cytometric bead assay(CBA). Methods To assay representative inflammatory cytokines of 40 patients of salpingitic infertility(PSI) and 40 healthy control by CBA, and compared 30 samples of serum with peritoneal fluid collected from identical subject. Results Experiment data displayed that in PSI the Th lymphocytes were decreased significantly (t =2. 1236,P <0. 05), Ts lymphocytes increased markedly, and the ratio of Th/Ts markedly decreased ( t = 2. 8392, P < 0. 01 ), compared with those of healthy control.(Pre-)inflammatory eytokines (IL-8, IL-1β, IL-6 and TNF-α) were all significantly higher than those of healthy controls ( t = 4. 9302,5. 5449,3. 4975,5. 6623, respectively, all P < 0. 01 ) ; while anti-inflammatory cytokines ( IL-10, IL-12 ), also increased markedly ( t = 5. 3428,5.9847, respectively, all P < 0. 01 ).Beside IL-10, all other cytokine concentrations presented in serum were higher than that of peritoneal fluid;IL-8(t =2.2113,P <0.05),IL-llS(t =2.9756,P <0.01), IL-6(t =2.3298,P <0.05), TNF-α (t =3. 2895, P < 0. 05 ), IL-12 ( t = 3. 3281, P < 0. 05 ), implying more sensitive of serum samples. Conclusion PSI displayed extensive disorders of the inflammatory cytokine network, CBA can be used to probe the disharmony condition at high through-out and high sensitivity.

Background and purpose:Oxaliplatin is a new cytotoxic platinum compound widely used in antineoplastic treatments.Peripheral neuropathy characterized by allodynia remains the most common way to limit the usage of oxaliplatin.Oxaliplatin-associated neuropathic pain is often resistant to standard analgesics.The effects of antidepressant agents such as desipramine and fluoxetine on chemotherapy-induced neuropathic pain were investigated so as to provide experimental evidence for clinical treatment.Methods:A single injection of oxaliplatin(30 mg/kg)intraperitoneal was injected into a test subject,a mouse that had chronic neuropathic pain.Using the von Frey filament as a touch stimulator,the mechanical withdrawal threshold(MWT)was measured when observing allodynia.The MWT was measured before and 1 h after the administration of desipramin and fluoxetine.Results:Desipramine and fluoxetine both have the potential to increase the MWT in mice with oxaliplatin-induced neuropathic pain.Pretreatment with antagonists such as an opioid receptor like naloxone could deepen their effects.Furthermore,when desipramine is combined with an opioid analgesic as buprenorphine,it causes an augmentation in the MWT.Conclusion:Antidepressants desipramine and fluoxetine antagonize oxaliplatin-induced neuropathic pain by inhibiting allodynia.Furthermore,the tricyclic antidepressing agent desipramine could enhance the effects of buprenorphine in subjects with oxaliplatin-induced pain,suggesting a synergistic effect for opioid analgesic.

Aim To investigate the effect of resveratrol on proliferation and differentiation in K562 cells. Methods K562 cells were treated with different con-centrations of resveratrol for 6d. The colony number of K562 cells was detected with semi-solid culture assay. Expression of GATA-1 and PU. 1 in K562 cells was re-spectively measured with immunocytochemistry and Western blot. Expression of differentiation related anti-gen, CD11b, CD14 and CD42b, was measured with flowcytometry on K562 cells. Results Resveratrol
could significantly decrease the colony number of K562 cells in a dose-dependent manner, and enhance the ex-pression of GATA-1,PU. 1,CD11b, CD14 and CD42b in K562 cells. Conclusion Resveratrol could inhibit the proliferation and induce differentiation of K562 cells via up-regulating the expression of GATA-1 and PU. 1 protein.
