Objective To observe the clinical efficacy of acupuncture at the trigger points on the back in treating cardioneurosis. Methods Fifty patients with cardioneurosis were selected to receive syndrome differentiation of traditional Chinese medicine, and then were evaluated for the improvement of symptoms respectively after first acupuncture treatment at the trigger points on the back and after 3~5 acupuncture treatments. Results Of the 50 cardioneurosis patients, 30 showed marked effect, 14 showed effective, 6 failed in the treatment, and the total effective rate was 88.0%. The total effective rate was 96.2%in patients of deficient heart yang, and was 75.0%in those of excessive fire due to yin deficiency, 83.3%in those of qi stagnation due to liver depression, and 83.3%in those of deficient heart yin. The improvement rate of subjective symptoms after 3~5 treatments was significantly different from that after the first treatment (P<0.05). Conclusions Acupuncture at the trigger points on the back is an effective approach in treating cardioneurosis, and it can achieve a marked efficacy with successive 3~5 sessions.

AIM: To investigate the effects of transforming growth factor ?1 (TGF-?1) on murine-derived dendritic cells (DC). METHODS: Murine bone marrow cells were cultured with GM-CSF and TGF-?1 to develop TGF ?-DC. Then they were stimulated by lipopolysaccharide (LPS). Their phenotypes were assessed by flow cytometry (FCM). The allogeneic stimulating capacity of DC was measured by mixed lymphocyte reaction (MLR) using BrdU ELISA method. IL-12 p70 protein was detected by ELISA and the expressions of Toll like receptor 4 (TLR4) on DCs were measured by semi-quantitative RT-PCR and FCM. RESULTS: Compared to immature DC (imDC) cultured with GM-CSF alone, the expressions of CD_80, CD_86, I-A~b and CD_40 in TGF ?-DC were lower. The TGF ?-DC was resistant to maturation by LPS. Maturation resistance was evident from a failure to up-regulate CMs, to stimulate larger T cell proliferation and to increase secretion of IL-12 p70. Down-regulation of TLR4 expression on TGF ?-DC was also found. CONCLUSION: TGF-?1 inhibits the expression of co-stimulatory molecules on DC. It is resistant to maturation stimulus (LPS) and might be linked with TLR4 down-regulation.

AIM: To explore the influence of CD47 molecules on the maturation and function of cultured dendritic cells (DCs). METHODS: Monocyte cell-derived DCs were propagated in granulocyte-macrophage colony-stimulating factor (GM-CSF) and lipopolysaccharide (LPS) plus interleukin (IL)-4, in the presence or absence of anti CD47 monoclonal antibodies (anti-CD47 mAbs). Flow cytometry was used to detect the cell surface phenotype. The concentration of IL-12P70 in supernatant was measured by ELISA technique. The antigen-presenting functions of DCs were determined in one-way mixed leukocyte reaction by Brdu-ELISA. Electrophoretic mobility shift assays (EMSA) was used to examine NF-?B activity. RESULTS: The anti-CD47 mAbs markedly suppressed the expression of CD80,CD86,CD83,CD1a,HLA-DR on the surface of DCs (P

Objective To investigate the pathological types and features of lymph nodes in human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(AIDS)patients with superficial lymphadenectasis.Methods The tissues of lymph nodes were obtained from 151 HIV/AIDS patients with superficial lymphadenectasis for pathological examination.The pathological results were observed by light microscope after Hematoxylin-Eosin(HE),acid-fast,periodic acid-Schiff (PAS),and digested-PAS(D-PAS)staining.The pathological results of lymph nodes were described and the correlation between pathological changes and CD4+T lymphocyte count was analyzed.Chisquare test was used for the statistic analysis.Results The benign lesions were found in 145 patients (96.0%),while the malignant tumors were found in 6 patients(4.0%).The pathological findings in the 151 HIV/AIDS patients included tuberculosis(72 patients),lymph node reactive hyperplasia(34patients),lymphatic fungal infections(23 patients,including penicillium diseases in 19 cases),AIDSrelated lymphadenectasis(14 cases),non-Hodgkin lymphoma(5 cases),benign fibrous histiocytoma (1 case).In addition,there were 83 patients(55.0%)with CD4+T lymphocyte count lower than 100×106/L.The frequency of penicillium diseases was higher in patients with lower CD4+T lymphocyte count(x2=7.757,P=0.021).Conclusions The major reasons for superficial lymphadenectasis in HIV/AIDS patients are infectious diseases,such as tuberculosis and fungal infections,which are common in patients with lower CD4+T lymphocyte counts.Non-Hodgkin lymphoma is the most common malignant tumor in this patient population.

Objective To investigate the application valve of bFGF to improve the viability of trans-plantation flap in Wistar rat. Methods Forty-eight Wistar rats were randomly divided into two groups based on the age: group A,B(1.5 month old, every group was 12 rats) and group C,D (3 month old, every group was 12 rats). After an ischemic model completed, recombinant bovine basic fibroblast growth factor (rb-bFGF) was given to groups A and C in ischemie zone by vascularization flap injection and the equality of normal saline to groups B and D. 14 days postoperatively, the muscular tissue was sent for histology, the blood vessel density was calculated by image analysis, and positive VEGF was detected by immunohistochem-istry. Results The member of capillaries and positive VEGF were more in group A than that in B, and also were morein group C than D(P < 0.05), but there were not statistic difference between group A and C (P > 0.05). Conclusion Recombinant bovine bFGF can stimulate angiogenesis and improve the ischemie vascu-larization flap of rat, which is not associated with their age.

ObjectiveTo study the effect of astragaloside Ⅳ(AS-Ⅳ) on glucose-induced podocyte adhesion and its possible mechanism. MethodsConditionally immortalized mouse podoeytes were treated with 10, 50, 100 mg/L AS-Ⅳ and with 100 mg/L AS-Ⅳ for 3, 6, 12, 24 h. Cell attachment was measured by fluorescence and centrifugation cell adhesion assays, respectively. Expression of α3β1 integrin mRNA and protein was examined by real-time PCR and Western blot. ResultsHigh glucose induced a significant reduction in adherent podocytes compared to normal glucose group (P<0.05). AS-Ⅳ improved high glucose-induced podocyte adhesion in a time- and dose-dependent manner. Real-time PCR and Western blot analysis revealed that high glucose-induced down-regulation of α3β1 integrin in podocytes were significantly meliorated by AS-Ⅳ (P<0.05). ConclusionAstragaloside Ⅳ improved high glucose-induced podocyte adhesion which may be mediated through α3β1 integrin up-regulation.

A method for measuring 13C isotopic abundance of intracellular metabolites of Saccharopolysporaerythraea by ultra-high performance liquid chromatography (UPLC)-triple quadrupole mass spectrometry was established.First, the chromatographic conditions of UPLC were optimized, and then the MS conditions such as unique tube lens voltage, collision energy, and ion pair were optimized.On the bases of length of the parent and daughter ions carbon chains and whether the daughter ions contain 13C atoms, the one-to-one method, one-to-many method and SIM method were established for measuring 13C isotopic abundance.Then these methods were used to measure naturally labeled intracellular metabolite standards and 13C labeled samples, and according to the gap between the experimental value and the theoretical value, the best method was established for each metabolite of different characteristics.The results showed that one-to-one method was most effective for measuring the metabolites of daughter ions not containing 13C atoms represented by sugar phosphates, one-to-many method was the best for measuring the metabolites of both parent and daughter ions containing 13C short carbon chains represented by carboxylic acids, SIM method could play a role in measuring the metabolites of both parent and daughter ions containing 13C long carbon chains represented by coenzyme A.This method had a good measurement precision and could be applied to the measurement of Saccharopolysporaerythraea intracellular metabolites, which contributed to the consequent study of metabolic mechanism and the efficient expression of erythromycin.

AIM: To analyze and identify the phosphoproteins associated with diazoxide preconditioning. METHODS: Proteomics technique was used to investigate the changes of phosphoprotein after diazoxide preconditioning. Adult rat ventricular myocytes were pretreated in the presence and absence of 200 ?mol/L diazoxide for 10 min. Phosphoproteins prepared and enriched respectively from control and diazoxide pretreated groups were then separated by two-dimensional (2D) gel electrophoresis and stained with sliver staining kit. Phosphoproteins of interest were further identified by mass spectrometry. RESULTS: Associated with diazoxide preconditioning, the proteins of chaperonin containing TCP-1 and hypothetical protein XP_346548 were phosphorylated significantly. The proteins of 94 kD glucose-regulated protein, calpactin I heavy chain and ferritin were dephosphorylated markedly (P
