Background Rectal carcinoma patients are often accompanied by hepatic metastasis. The aim of this study was to evaluate the therapeutic efficacy of simultaneous laparoscopic excision for rectal carcinoma with synchronous hepatic *** A total of 41 patients with rectal carcinoma and synchronous hepatic metastasis detected by CT scan were included in this study. Among them, 23 patients underwent laparoscopic surgery and 18 patients underwent traditional open surgery to simultaneously remove the rectal tumor and hepatic metastasis lesions. All patients received postoperative adjuvant chemotherapy. All the patients were followed up from 36 to 72 months （mean 45.3 months）.Results All the operations were performed successfully and no patient was turned to open surgery in laparoscopic group. The mean blood loss, the mean postoperative hospital stay, the mean blood transfusion and the mean intestinal functional recovery time showed a significant difference between the two groups （P〈0.05）. The 1-, 3- and 5-year survival rates were 82.6%, 43.5% and 8.6% in the laparoscopic group, without significant difference compared with the open group （77.8%, 38.9% and 0）（P〉0.05）.Conclusions Simultaneous laparoscopic excision for rectal carcinoma and synchronous hepatic metastasis is safe and effective with similar survival achieved by the traditional open abdominal surgery.

Rare earth metal-organic frameworks (RE-MOFs) have drawn wide attention owing to diverse network structures and various application ***,due to the unpredictable formation of the nodes,it is still challenging to design novel RE-MOFs.A novel versatile strategy was developed employing a RE-acetate complex (RE2(CH3COO)6·4H2O) as a precursor to construct RE-MOFs.2D RE-MOFs (RE-DBP) and 3D RE-MOFs (RE-TCPP) could be obtained by using dicarboxylic porphyrin ligands H2DBP and tetracarboxylic porphyrin ligands H2TCPP,*** RE-MOFs were further synthesized to verify the universality of the *** crystalline RE-MOFs could also be prepared at room temperature via the developed strategy,which could significantly promote large-scale preparation and practical application of *** proof of the concept,the performance of porphyrin-based RE-MOFs was investigated in the photocatalytic cycloaddition of CO2with *** the RE-DBP(Co) MOFs,Tb-DBP(Co) exhibited the best photocatalytic performance,which was also greater than that of the corresponding 3D MOF Tb-TCPP(Co) due to the optimal 2D structure and thus the accelerated photogenerated charge separation and transfer *** work not only provides a novel versatile strategy to design and develop RE-MOFs,but also proposes a promising approach for the potential bulk production of RE-MOFs at room temperature.

目的研究功能矫形前伸青春期大鼠下颌后,前伸下颌的浅层嚼肌细胞膜乙酰胆碱受体最大结合容量和亲和性的变化,探讨功能矫形的神经肌肉调控机制。方法选用40只5周龄SD雄性大鼠,随机分为实验组和对照组各20只。实验组大鼠戴自制上颌功能矫治器,引导下颌前伸,对照组不戴。采用放射受体分析法测定2组大鼠浅层嚼肌肌细胞膜上乙酰胆碱受体的最大结合容量和亲和性值。结果实验组大鼠浅层嚼肌细胞膜上乙酰胆碱受体最大结合容量明显增加,具有高度亲和力,大于对照组。结论功能矫形可增加浅层嚼肌细胞膜上乙酰胆碱受体与乙酰胆碱的结合量及亲和力,导致肌肉的结构与功能发生适应性改建。
