Using model results from the first phase of the Pliocene Model Intercomparison Project （PlioMIP） and four experiments with CAM4, the intensified African summer monsoon （ASM） in the mid-Piacenzian and corresponding mechanisms are analyzed. The results from PlioMIP show that the ASM intensified and summer precipitation increased in North Africa during the mid-Piacenzian, which can be explained by the increased net energy in the atmospheric column above North Africa. Further experiments with CAM4 indicated that the combined changes in the mid-Piacenzian of atmospheric CO2 concentration and SST, as well as the vegetation change, could have substantially increased the net energy in the atmospheric column over North Africa and further intensified the ASM. The experiments also demonstrated that topography change had a weak effect. Overall, the combined changes of atmospheric CO2 concentration and SST were the most important factor that brought about the intensified ASM in the mid-Piacenzian.

肥胖是一种慢性代谢性疾病,与2型糖尿病、心血管疾病、高血压病、癌症、代谢综合征和慢性肾脏疾病的患病风险呈线性相关,未来由此引起的肥胖健康负担将急剧增加。因此如何治疗肥胖及其继发性疾病,已成为患者、医生和社会迫切需要解决的问题。目前防治肥胖的中西医方法较多,但如何将中西医方法进行整合,实现临床效果最大化,仍然是值得探索的问题。近几年,作者在代谢与肥胖专病门诊的临床实践中,尝试使用中西医结合阶梯疗法治疗肥胖症,希冀探索出整合中西医方法的治疗模式。此文呈现1例疗程近2年的中西医结合阶梯疗法治疗肥胖症的典型案例。

Objective： In recent years, the combination of cetuximab and chemoradiotherapy （CRT） has been used to treat stage III non-small cell lung cancer （NSCLC）; however, limited data are available for Chinese patients. Herein, we report preliminary data from a phase I/II study testing the combination of cetuximab with inductive chemotherapy, followed by concurrent CRT （CCRT） in Chinese patients with stage III NSCLC. Methods： Eligibility criteria were Zubrod performance status （PS） 0-1, forced expiratory volume in 1 second （FEV1）〉_1.2 L and adequate organ function. Enrolled patients received weekly cetuximab （initial dose of 400 mg/m2 on day 1 of week 1 and a maintenance dose of 250 mg/m2 on week 2 to the end of CCRT） with cisplatin/vinorelbine （NP） chemotherapy （every 3 weeks for 2 cycles from week 2, followed by two cycles of concomitant NP chemotherapy and intensity-modulated thoracic radiotherapy （TRT）（60-66 Gy/2 Gy）. The primary endpoints were toxicity and feasibility. All patients received positron emission tomography- computerized tomography （PET-CT） scans within the 2 weeks prior to enrollment. Univariate analyses were used to assess the correlation between SUV-T, SUV-N, SUV-TOTAL, gender, age, histology, tumor-node- metastasis （TNM） stage, PS and smoking status and survival. Survival curves were generated for different populations using the Kaplan-Meier method and compared using a log-rank test. Results： Seventeen patients were enrolled and 16 completed the full regime. The overall response rate （ORR） was 58.8% and 82.3% after the induction and CCRT phases, respectively. With a median follow-up duration of 27.6 months, the median survival was 27.6 months [95% confidence interval （CI）： 11.3-43.9 months] with 1- and 2-year survival rates of 88.2% （95% CI, 60.6-96.9%） and 58.8% （95% CI, 60.6-77.8%）, respectively. Three patients remain progression-free to date, and the median progression-free survival （PFS） was 13.5 months （95% CI, 6.8-20.2 months）. No treatment-rela

Here, we propose a simple scheme to realize a one-dimensional （1D） modulated Rice-Mele model （RMM） and investigate its topological properties with a 1D circuit quantum electrodynamics （QED） lattice. The system can be mapped into a Chern insulator model by introducing a period parameter. Interestingly and surprisingly, we found that the circuit-QED lattice system always exhibits topologically nonttrvial phases if both the nearest-neighbor hopping strength between two resonators and the qubitassisted on-site potentials are alternately changed in the direction of the lattice. The numerical results show that the topological phases can be obtained by introducing an additional modulation parameter and both the edge state and topological invariant can be unambiguously seen with the existence of decay and disorders, even with few resonators in the lattice.
