Objective:To observe the clinical efficacy of the combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium in the treatment of allergic rhinitis and its influence on inflammatory cytokines. Methods:Totally 94 cases of al-lergic rhinitis patients received treatment in our hospital were selected and divided into the observation group and the control group ran-domly. The control group received budesonide nasal spray and desloratadine citrate disodium, and the observation group received mon-telukast additionally. After 4-week treatment, the changes of clinical symptoms and the contents of IL-6, IL-8 and IL-10 in the two groups were compared. The clinical efficacy of the two groups was also compared. Results:After the treatment, the VAS score of the nasal symptom and category symptoms in the two groups were lower than that before the treatment, and the score of the observation group was lower than that of the control group (P<0. 05). After the treatment, the contents of IL-6 and IL-8 were significantly re-duced while the content of IL-10 was significantly increased in the two groups, and the changes in the observation group were more no-table than those in the control group (P<0. 05). The total effective rate of the observation group was 91. 49%, which was higher than that of the control group (80. 85%, P<0. 05). Conclusion:The combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium can significantly improve the clinical symptoms, reduce the IL-6 and IL-8 levels and increase the IL-10 content in allergic rhinitis patients.

Objective To determine the effect of apoptosis in different host cells induced by L. in- terrogans and the associated intracellular signaling pathway. Methods L. interrogans serogroup Icterohaem- orrhagiae serovar icterohaemorrhagiae strain Lai infected cell models in mouse mono-macrophage like cell J774A. 1, human EVC304 cells and A549 cells were established, respectively. Flow cytometry with fluores- cein labeling of FITC-Annexin V/PI was performed to examine the apoptosis or necrosis of the infected cells. Fluorometry as well as Western blot assay was applied to measure the activity of caspase-3, -8, -9 and the expression levels of apoptotic associated protein FADD in the infected cells , respectively . Results 36.70%-63.70% of the L. interrogans strain Lai infected J774A. 1 cells displayed obvious early apoptosis during the infection for 1-6 h, and then altered to later apoptosis / necrosis (53.68%) as the major injury pattern when infected for 12 h. 78.52% of the L. interrogans strain Lai infected A549 cells only showed later apoptosis / necrosis. However, no obvious apoptosis and / or necrosis could be found in the L. interrogans strain Lai infected EVC304 cells. The maximal activities of caspase-3 and -8 in the infected J774A. 1 cells were (1453.41±36.07) and (1402.15± 59.09) FU, respectively, which were the 16.38-fold and 29.99- fold of those the non-infected cells. The caspase-9 activity of the infected J774A. 1 cells slightly increased [(89.42±5.08) FU ], which significantly lower than those of caspase-3 and -8 (P <0.001). The FADD expression level of the infected J774A. 1 cells was gradually increased in an infection time-dependent man- ner. Conclusion There is a distinct diversity of apoptosis in different cells induced by L. interrogans, and FADD→caspase-8→caspase-3 is the major signaling pathway to mediate L. interrogans infection associated cell apoptosis.

Objective To evaluate the effects of hydroxyethyl starch (HES) on the renal function and blood coagulation of patients with acute pancreatitis (AP). Methods 151 patients with acute pancreatits were divided into treatment group (treated with HES, n=62) and control group (treated with crystalloid solutions, n =89). The two groups were compared by retrospective analysis of the indices such as serum creatinine (Scr), blood urea nitrogen (Bun), platelet count(Plt), prothrombin time activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT) and fibrinogen (FIB) before and after treatment. Results Before hospitalization, there were insignificant differences in respect of Scr and Bun in the two groups respectively. But at discharge, Scr and Bun in the treatment group were significantly increased (P<0.05), while Bun was significantly decreased 24 h right after infusion of crystalloid solutions in the control group (P<0.05). There were no differences between the two groups in terms of Scr and Bun. As for indices of coagulation, APTT in the treatment group was significantly increased after infusion of HES (P<0.05). The hospital stay in the treatment group was longer than the control group (P < 0.05). Conclusions HES may adversely affect renal function and intrinsic pathway of blood coagulation of patients with AP. Renal function and blood coagulation should be monitored when using HES.
