OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

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.

We have reported that hypoxia increases the activation of 15-lipoxygenase (15-LO), which converts arachidonic acid (AA) into 15-hydroxyeicosatetraenoic acid (15-HETE) in small pulmonary arteries (PAs). Through inhibition of Kv channels, 15-HETE causes more robust concentration-dependent contraction of PA rings from the hypoxic compared to the normoxic controls. However, the subtypes of Kv channels inhibited by 15-HETE are incompletely understood. The aim of the present study was to identify the contribution of Kv3.4 channel in the process of pulmonary vasoconstriction induced by 15-HETE using the tension studies of PA rings from rat with Kv3.4 channel blocker in tissue bath; to explore the role of vascular endothelium in15-HETE-induced pulmonary vasoconstriction through denuded endothelia of PA rings; and to define the downregulation of 15-HETE on the expression of Kv3.4 channel in cultured pulmonary artery smooth muscle cells (PASMCs) with RT-PCR and Western blot. In the present study, healthy Wistar rats were divided randomly into two groups: Group A with normal oxygen supply and group B with hypoxia. Six days later, the rats were killed. Pulmonary artery rings were prepared for organ bath experiments. Firstly, different concentrations of 15-HETE (10~1 000 nmol/L) were added to the Krebs solution. The isometric tension was recorded using a four-channel force-displacement transducer. Then Kv3.4 channel blocker, 100 nmol/L BDS-I, was added, followed by adding 1 mumol/L 15-HETE, and the isometric tension was recorded. Furthermore, RT-PCR and Western blot were employed to identify the influence of 15-HETE on the expression of Kv3.4 channel in cultured rat PASMCs.The results showed the PA tension was significantly increased both in groups A and B by 15-HETE in a concentration-dependent manner (P<0.05), especially in group B (P<0.05 compared to control); denuded endothelia enhanced 15-HETE concentration-related constrictions in rat PA rings; Kv3.4 channel blocker, BDS-I, significantly decreased the PA ring constriction induced by 15-HETE (P<0.05); the expressions of Kv3.4 mRNA and protein in rat PASMCs were significantly downregulated by 15-HETE (P<0.05). Based on all the information above, we conclude that Kv3.4 channel is involved in vasoconstriction induced by 15-HETE in rat PAs.
