OBJECTIVE:To study whether there is interaction between ambroxol hydrochloride and amino?phylline.METHODS:16volunteer were randomly divided into trial group and control group.The blood concentration of amin_ ophylline was determinated with HPLC method,then the main parameters of pharmacokinetics of aminophylline were calculated with3p97software.RESULTS:The main parameters of pharmacokinetics of aminophylline in trial and control group were:K e (0.062?0.023)/h and(0.0905?0.013)/h;V(22.83?7.85)and(23.27?3.78)L;T 1/2 (12.51?4.2)and(7.77?0.89)h;AUC 0～21 (426.59?186.92)and(245.74?48.6)(mg?h)/L;CL(s)(23.17?9.83)and(34.84?6.00)ml/min respective?ly.CONCLUSION:Although ambroxol hydrochloride did not influence the distribution of aminophylline,but it could prolong the half time of aminophylline and increase the stagnation time of aminophylline in vivo.

Objective To investigate the feasibility, safety and effectiveness of stent-assisted coil embolization for the treatment of intracranial wide-necked aneurysms. Methods The clinical and imaging data of the patients with intracranial wide-necked aneurysm treated with stent-assisted coil embolization were analyzed retrospectively. Results A total of 200 patients with 205 aneurysms were enrolled. The mortality was 1. 5% and the disability rate was 1. 0% at discharge. One hundred seventy-seven patients were followed up for 16-51 months. The modified Rankin Scale scores: 0 in 174 cases, 2 in 2 cases, 4 in 1 case. Eleven patients (5. 5% ) had perioperative complications, including intraoperative bleeding in 3 cases, postoperative bleeding in 3 cases, postoperative cerebral infarction in 2 cases, coil protrusion in 2 cases, and postoperative epileptic seizure in 1 case. Univariate analysis showed that there were significant differences in the proportions of male patients (9. 1% vs. 5. 3% ; χ2 = 4. 42, P = 0. 026), hypertension (54. 5% vs. 23. 3% ; χ2 = 5. 42, P = 0. 03) and stent prior to coil implantation (54. 5% vs. 85. 1% ; χ2 = 3. 54, P =0. 021) between the complication group and the noncomplication group. Multivariate logistic regression analysis showed that the pre-stenting was an independent protective factor for surgery-related complications (odds ratio [OR] 0. 208, 95% confidence interval [CI] 0. 055-0. 791; P = 0. 021), and hypertension was an independent risk factor for surgery-related complications (OR 4. 380, 95% CI 1. 170-16. 399; P = 0. 028). The imaging follow-up of 167 aneurysms was obtained, including 26 recurrent aneurysms (15. 6% ). Univariate analysis showed that there was significant difference in the aneurysm site (anterior circulation aneurysms: 73. 1% vs. 89. 1% ; posterior circulation aneurysms: 26. 9% vs. 10. 6% ; χ2 = 5. 09, P = 0. 033) and size (giant aneurysms: 7. 7% vs. 0. 7% ; large artery aneurysm: 65. 4% vs. 29. 1% ; small aneurysms:26. 9% vs. 70. 2% ; χ2 = 20. 77, P < 0. 001) between the recurrence group and the nonrecurrence group. Multivariate logistic regression analysis showed that large aneurysms (OR 6. 057, 95% CI 2. 296-5. 983; P <0. 001), giant aneurysms (OR 25. 260, 95% CI 1. 903- 335. 267; P = 0. 014 ), and posterior circulation aneurysms ( OR 3. 184, 95% CI 1. 028- 9. 857; P = 0. 045 ) were the independent risk factors of postoperative recurrence. Conclusions Stent-assisted coil embolization is one of the effective methods for the treatment of complex wide-neck aneurysms. Hypertension and coils prior to stenting are the independent risk factors for perioperative complications, and larger aneurysm size and aneurysms in the posterior circulation are the independent risk factors for postoperative recurrence.

Nuclear factor(NF)-κB is widely expressed in various types of tissue cells. Abnormal activation of NF-κB signaling pathway can lead to the initiation and progression of asthma,chronic ob?structive pulmonary disease(COPD)and other lung inflammatory diseases,but inhibition of its activity can effectively alleviate the occurrence and development of these diseases. In this paper ,we review biological characteristics of NF-κB,role of NF-κB signaling in asthma,COPD and other inflammatory lung diseases,and potential application of NF-κB inhibitors in clinical treatment of these inflammatory lung diseases. It will provide a valuable reference for further study on pathogenesis,prevention,and control of lung inflammatory diseases.

Type II innate lymphoid cells ( ILC2s) are widely distributed in the blood , intestines, trachea, lung, spleen, liver, animal fat and skin, and involved in the innate immune responses .ILC2s have attracted much atten-tion for its important roles in the conversion of white adipose to beige adipose .Studies have shown that ILC2s are essential for the proliferation and differentiation of adipocyte precursor cells , and they also play a vital role in anti-parasitic infection and allergic inflammation .This review discusses the discovery , differentiation , development , distribution and function of ILC2s, and their relationships with the browning of white adipose tissue for providing valuable references on understanding the pathogenesis , prevention and treatment of obesity and fat metabolism disorders .

Objective: To compare the treatment effect of surgical clipping and endovascular coil embolization for aneurysmal subarachnoid hemorrhage (aSAH) in the elderly. Methods: Elderly patients with aSAH (aged >65 years) treated in Shanghai Pudong Hospital from January 2009 to December 2017 were enrolled retrospectively. They were divided into craniotomy clipping group and endovascular intervention group according to the treatment strategy. The Glasgow Outcome Scale was used for short-term outcome assessment at discharge, 4-5 were defined as good outcome, and 1-3 were defined as poor outcome. Long-term follow-up was performed to assess clinical outcomes using the modified Rankin Scale, 0-2 was defined as good outcome and 3-6 were defined as poor outcome. The clinical and imaging information, perioperative complications, short-term and long-term clinical outcomes, and long-term imaging outcomes were compared between the two groups. Multivariate logistic regression analysis was used to assess the independent influencing factors of clinical outcomes. Results: A total of 68 elderly patients with aSAH were enrolled. Of these, 47 (69.1%) received endovascular coil embolization and 21 (30.9%) underwent microsurgical clipping. There were no significant differences between the two groups in the incidence of perioperative complications, short-term and long-term adverse outcomes, and imaging recurrence rate. Multivariate logistic analysis showed that smoking (odds ratio [OR] 36.319, 95% confidence interval [CI] 3.530-373.640; P=0.003), modified Fisher grade (OR 20.406, 95% CI 2.022-205.964; P=0.011) and World Federation of Neurological Societies (WFNS) grade (OR 4.686, 95% CI 1.012-21.692; P=0.048) were the independent risk factors for short-term poor outcomes in elderly patients with aSAH. Conclusion Both endovascular intervention and microsurgical clipping are safe and effective treatments for elderly patients with aSAH.
