OBJECTIVETo observe the difference of the clinical effects of different needle retention times for acute lumbar sprain treated with float needle.

METHODSOne hundred and twenty patients with acute lumbar sprain were randomly divided into a 6 h group, a 12 h group, a 24 h group and a western medication group, 30 cases in each one. In the three float needle groups, plastic hose was detained near the pressure pain point on the lumbar after subcutaneous scattering with float needle. The needle retention time was 6 h, 12 h and 24 h respectively. In the western medication group, 75 mg voltaren tablet was adopted orally every day and the treatment was given for four days. Visual analogue scale (VAS) and Oswestry dysfunction index (ODI) about low back pain were observed before and after treatment. Also, the comprehensive effect was assessed after treatment.

RESULTSAfter treatment, the VAS scores and the ODI scores were improved obviously than those before treatment in all groups (all P< 0. 05). In the three float needle groups, the VAS scores and the ODI scores were superior to those in the western medication group (all P<0. 05). The differences in VAS scores and ODI scores among the three float needle groups were not statistically significant after treatment (all P>0. 05). The effective rate in the 6 h, 12 h and 24 h group was 93. 3% (28/30), 90. 0% (27/30) and 93. 3% (28/30) respectively, which were better than 73. 3% (22/30) in the western medication group (all P<0. 05).

CONCLUSIONThe effect of float needle for acute lumbar sprain is better than voltaren, and there is no apparent difference in retention times.

Objective To study the expression of thymic stromal lymphopoietin(TSLP) and the activation of DCs in OVA-induced murine asthma model, and investigate the effects and underlying mecha-nisms of TSLP on lung inflammation. Methods Thirty BALB/c mice were randomly divided into control group, OVA group and TSLP neutralizing antibody treated group. The asthma model was evaluated by airway responsiveness and histological analysis of lung tissues ; The levels of TSLP mRNA in lungs were determined by quantitative real-time PCR; The expression of TSLP in lungs were determined by immunohistochemistry and Western blot; The expression of CD40, CD80, CD86 in BALF was detected by FACS. Results Both the histological analysis of lung tissues and the airway responsiveness were all consistent with the characteris-tic of murine asthma model. The expression of TSLP and TSLP mRNA in the OVA group was significantly in-creased compared with blank group. The expression of CD40, CD80, CD86 in BALF from OVA group was increased significantly compared with the control group. Furthermore, treating mice with TSLP neutralizing antibody reduced the expression of CD40, CD80, CD86 on dendritic cells, and IL-4, IL-5, IL-13 in the OVA group. Conclusion Our study indicate that TSLP was highly expressed in the bronchial epithelia of murine asthma model, via upregulation of CD40, CD80, CD86, induce DCs to active CD4~+ T cells and pro-duce type 2 responses, so that aggravating the lung inflammation of asthma. Blocking TSLP is capable of in-hibiting the production of Th2 cytokines, thus presents a promising strategy for the treatment of asthma.

AIM: To observe the different changes of neuroendocrine systems between the state of sport fatigue and poverty of movement. METHODS: 60 male Wistar rats were randomly divided into three groups: normal control group, sport fatigue model group and poverty of movement model group (20 rats in each group). The sport fatigue model was established by the method of combining basal diet and loaded swimming during 2 weeks, whereas the method of restricted activities was used to establish the poverty of movement model with total experimental time of 10 weeks. By the end of experiment, the climbing pole time was determined. The contents of hypothalamus thyrotropin releasing hormone (TRH), and serum norepinephrine (NE) and epinephrine (E) in rats with different treatments were determined by ELISA. In addition, the changes of hypothalamus corticotropin release hormone (CRH), pituitary adrenocorticotropic hormone (ACTH) and thyroid stimulating hormone (TSH), and serum corticosterone (CORT), triiodothyronine (T_3), tetraiodothyronine (T_4) were determined by radioimmunoassay to evaluate the functions of adrenergic nerve-adrenomedullin system, hypothalamo-pituitary-adrenal (HPA) axis and hypothalamo-pituitary-thyroid (HPT) axis. RESULTS: Compared to control group, the climbing pole time of the animals was obviously decreased in two model group. The adrenergic nerve-adrenomedullin system and HPA axis were inhibited in sport fatigue model rats, but HPT axis was unchanged. Interestingly, the HPA axis was hyperfunctional and HPT axis was inhibited in poverty of movement model rats. However, no change in the adrenergic nerve-adrenomedullin system was observed. CONCLUSION: Sport fatigue and poverty of movement all affect neuroendocrine system and lead to the adjustment mechanism imbalance, but the target and tendency are different.

Objective: To observe the effect of oxidative-low density lipoprotein (ox-LDL) injured human leukemia mononuclear cells (THP-1) adhesion to human umbilical vein endothelial cells (HUVECs)in vitrowith the intervening function of dredging collateral drug, tongxinluo (TXL) and ginsenoside (Rb1). Methods: Cell injury was induced by ox-LDL treatment. The cells were divided into 4 groups:①Normal control group,②Injury model group, the cells were cultured by ox-LDL,③TXL group, the cells were cultured with both ox-LDL and TXL,④Rb1 group. HUVEC viability was measured by MTS assay, adherence rate of THP-1 cells to HUVECs was tested by vital cell staining. The contents of monocyte chemoat-tractant protein (MCP-1), soluble vascular cell adhesion molecule (sVCAM-1), soluble inter vascular cell adhesion molecule-1 (sICAM-1) and E-selectin in HUVEC conditioned medium were detected by ELISA; protein expressions of CCR2, VLA4 and Mac-1 in THP-1 cells were examined by Western blot analysis. Results: Compared with Control group, HUVEC viability was decreased in Injury model group (100 ±1.31) % vs(75.57 ± 1.02) %, while increased in both TXL and Rb1 groups (99.25 ± 1.40) % and (99.48 ± 2.15) %; Injury model group showed elevated adherence rate of THP-1 cells to HUVECs, while the adherence rates were reduced in both TXL and Rb1 groups. Compared with Injury model group, TXL group and Rb1 group showed decreased levels of MCP-1, sVCAM-1, sICAM-1 and E-selectin in HUVEC conditioned medium; decreased protein expressions of CCR2, VLA4 and Mac-1 in THP-1 cells. Conclusion: TXL and Rb1 could protect HUVECs, reduce ox-LDL injury induced vascular endothelial cell adhesion and decrease relevant receptor expression in monocytes; therefore, inhibit injured monocytes adherence to vascular endothelial cells.

Endothelial to mesenchymal transition(EndMT) plays a major role during organism development, and also contributes to several adult cardiovascular diseases.EndMT-derived fibroblast-like cells are common in atherosclerotic lesions.Pro-atherosclerosis factors, such as oxidative stress, hypoxia, inflammatory cytokines and oscillatory fluid shear stress can promote EndMT.EndMT is closely associated with plaque calcification, and unstable and ruptured plaque phenotype that may prone to cause clinical events.EndMT may be another key step in the prevention and treatment of atherosclerosis.Here, we reviewed the role played by endothelial-to-mesenchymal transition(EndMT) and its key regulators in atherosclerosis.
