Objective To inestigate the effect of inhaled steroid hormone on the IL-16 in sputum from paitents with asthma, and to explore the mechanism of anti-inflammation of steroid. Method Budesonid inhalant were administered(400?g twice a day) persistent 4 weeks for 12 subjects with mild to moderate asthma, The percentage of eosinophils and IL-16 in induced sputum were determined in every subject .Result After the course , the concentration of IL-16 in sputum was (41 5?5 2)ng/L, significantly lower than that before the therapy which was (58 2?7 2)ng/L,P

Objective To compare the immune regulation of syngenic and allogenic mesenchymal stem cells (MSCs) in the transplantation combined with islets. Methods After induction of diabetes in 30 Lewis rats with streptozotocin (STZ), the recipient Lewis rats received islets from SD rats combined with syngenic (group B) or allogenic (group C) MSCs injection via the portal vein. The group of islets transplanted alone served as control (group A). The survival time of grafts in all groups was assessed by the level of blood glucose. ELISA was used to detect the levels of interferon-γ (IFN-γ), interleukin 2 (IL-2), IL-4 and IL-10 in the peripheral blood on the 1st and 3rd day after transplantation. Results The blood glucose levels in all three groups were decreased in a normal range (13. 9 mmol/L) and the survival time of grafts in group B (11.38 ± 4. 03 days) was significantly longer than in group C (5. 50± 2. 07 days) as well as group A (2. 88 ± 1.25 days). On the 1 st and 3rd day after transplantation, the levels of TH 1 cytokines IFN-γ and IL-2 in group A were significantly higher than in groups C and B (P＜0.05). Meanwhile the levels of TH 2 cytokine IL-10were increased in group B, but there was no significant difference between groups A and C (P＞0.05). The levels of IL-4 had no significant difference among these three groups (P ＞ 0.05).Conclusion Islet transplantation combined with MSCs could prolong the survival time of grafts.Syngenic MSCs, superior to allogenic ones, were more effective in changing the balance of TH1/TH2to TH2. Decreased expression of TH1 cytokine (IFN-γ, IL-2), which was closely related to the induction of immune tolerance, was beneficial to the long-term survival of grafts.

Objective To investigate the effect and safety of Compound codeine phosphate syrup with Ambroxol treatment in the stable phase of chronic obstructive pulmonary disease. Methods 100 patients with stable COPD were divided into Compound codeine phosphate syrup with Ambroxolt treatment group (Group A) 50 cases and Compound codeine phosphate syrup treatment group( Group B) 50 cases,drug were given for 3 ～ 7d. The symptom score and efficacy of two groups before treatment and after treatment were compared. Results The symptom score of cough,sputum volume,sputum viscosity ,wheeze,sleep after treatment 8th day were improved significantly ( χ2 = 3. 891 ,χ2 =3. 992, χ2 = 4. 198, χ2 = 3.981, χ2 = 3. 879, allP < 0. 05; Total effective rate of cough, sputum volume, sputum viscosity,wheeze in group A(92. 0% ,94. 0% ,90. 0% ,90. 0% ) higher than that in group B(80.0% ,86.0% ,80. 0%,78.0% ) ( χ2 = 3.991, χ2 = 4. 012, χ2 = 3. 998, χ2 = 3.971, allP < 0. 05); The adverse reactions of A、 B group were 12.0% and 14.0%(χ2 =1.971,P>0.05). Conclusion Compound codeine phosphate syrup with Ambroxol is an effective and safe antitussive in the stable phase of chronic obstructive pulmonary disease.

Tachycardia-induced cardiomyopathy (TIC) is defined as a kind of cardiomyopathy with cardiac dilatation and dysfunction secondary to sustained or recurrent tachyarrhythmia.Myocardial dysfunction can wholly or partially recover after control of the responsible tachyarrhythmia.TIC,a reversible acquired cardiomyopathy with generally benign prognosis,can occur at any age;however,it often proves to be unrecognized by most of pediatricians in clinical practices.Now,the clinical criteria,pathogenesis,characteristics,therapy and prognosis of pediatric TIC were summarized,so as to provide a clinical basis for early recognition and prompt therapy.

Objective To evaluate the efficacy and safety of high-dose ambroxol in treating acute exacerbations in chronic obstructive pulmonary disease (AECOPD).Methods The trial design was random,open,and parallel control.126 patients with AECOPD were involved.High-dose group received ambroxol 150 mg 3 times per day for 7 days (n=46),while conventional-dose group given ambroxol 30 mg 3 times per day for 7 days (n=40) and control group was given a routine treatment (antibiotic therapy,oxygen inhalation and bronchodilators) (n=40).Results The effective rates of high-dose group and conventional-dose group (95.6 ％,77.5 ％) were significantly higher compared with control group (55.0％) (x2 =19.81,4.53,both P＜0.05).The average duration of hospitalization was significantly lower in high-dose group (10.78 ±0.95)d and conventional-dose group (11.75±0.84)d comparing with control group (13.15±0.89)d (q=11.88,7.24,both P＜0.05).The clinical efficacy in high dose group was much better.Conclusions High-dose ambroxol is a safe and efficient therapy in the treatment of acute exacerbations in chronic obstructive pulmonary disease.

Objective To study level of the expression of RAR? mRNA in the skin lesions of patients with psoriasis vulgaris. Methods The biopsies were taken from skin lesions in 20 patients with psoriasis vulgaris and the skin of 10 normal controls, and levels of RAR? mRNA were investigated with RT-PCR. Results The level of RAR?mRNA was significanlly lower in the epidermis of patients with psoriasis vulgaris than that in the control(P

Objective To study the level of expression of RAR?/RXR?mRNA in skin lesions of patients with psoriasis vulgaris.Methods The skin biopsies were collected fro mskin lesions in 20cases of psoriasis vulgaris and 10normal controls.Expression o f RAR?/RXR?mRNA was detected by RT -PCR.Results Expression levels of RXR?mRNA were 0.19760?0.0933in epiderm ides from psoriatic lesions,which were markedly lower than those in normal controls(0.5867?0.0132)(P0.05).Conclusion The results indicate that decreased expression of RXR?mRNA might be related to the pathogen esis of psoriasis.

Objective To observe the effect of hepatocyte growth factor on preserving isolated heart of rats. Methods Forty rats were random divided into two groups: Control group(n=20)which rat hearts were isolated and preserved in 4℃HTK solution, and experimental group(n=20)which rat hearts were isolated and preserved in 4℃ HTK+rh-HGF(100μg/L)solution. Before operation and rat hearts were subjected to 8 hours(groupA,C)or 12 hours(group B,D)hypothermic storage followed by 5 minutes of normothermic reperfusion onmodifiedLangendorff-Neely model. The recovery rate of cardiac function after myocardial preservation, such as LVSP and LVDP and±dp/dt max and the changes of CK,LDH,NO and ET were measured. Cell apoptosis was detected by TUNEL staining and the expression of c-met was analyzed by immunohistochemical method. The expression change of bcl-2 mRNA was examined by RT-PCR. Results Compared with control group, experimental group showed that a significantly higher recovery rate of LVSP,LVDP and±dp/dt max(P＜0.01) and lower rate of TUNEL positive cardiomyocytes(P＜0.01) after reperfusion. The leakage of CK and LDH was significant lower than that of control group(P＜0.01). Immunohistochemical analysis revealed that c-met receptor expression was stronger in the HGF-treated myocardium than that in the non HGF-treated myocardium after storage, and this was associated with a stronger expression of bcl-2 mRNA. Conclusion The administration of rh-HGF before storage improved cardiac function after prolonged myocardial preservation by preventing apoptosis and enhancing expression of bcl-2 mRNA. Thus, the addition of rh-HGF in the storage solution may be a promising strategy for prolonged heart graft preservation.

Despite the incidence of gastric cancer is decreasing, it remains the fourth most common malignancy and the second leading cause of cancer-related death around the world. The prognosis of gastric cancer is still poor and surgery is the mainstay treatment. Lymph node dissection plays an important role in the surgery of gastric cancer due to the high incidence of lymph node metastasis and recurrence. There has been a consensus between the West and the East that D2 lymph node dissection is the standard dissection for advanced gastric cancer. Some clinical trials have showed good results of neoadjuvant chemotherapy in advanced gastric cancer. Large sample randomized controlled studies are needed to confirm the value of neoadjuvant chemotherapy.
