Objective: To evaluate the significance of intraopera- tive reassessment of liver function reserve in the se- lection of surgical procedures to optimize therapeutic results in the treatment of portal hypertension. Methods: The data of 146 patients with portal hyper- tension treated in the past 10 years were retrospec- tively reviewed. Posthepatitis cirrhosis was found in 118 patients, schistosomial cirrhosis in 6, alcoholic cirrhosis in 1, mixed cirrhosis in 5, and other disea- ses in 16. According to Child's criteria, 45 patients were classified into class A, 92 class B, and 9 class C. At operation, 33 patients were reclassified into class A, 78 class B, and 35 class C. Disconnection procedure was performed in 89 patients (61. 0%) and shunt procedure in 57 (39. 0 %). These opera- tions included prophylactic operations in 27 patients (18. 5 %) and emergency disconnection operations in 2 (1. 4%). Results: One patient (0. 7 %) died of upper gastroin- testinal bleeding during operation. Early rebleeding following operation occurred in 9 patients (6. 1%) (disconnection in 5 patients and shunt in 4). Early encephalopathy after operation occurred in 2 patients (1. 4 %) (disconnection in 1 patient and shunt in 1). A total of 98 patients (67. 6%) (disconnection in 61 patients and shunt in 37) were followed up (6 months to 9 years). Bleeding occurred again in 12 patients (12. 2 %) (disconnection in 9 patients and shunt in 3) 17 months after operation (4 to 41 months). Late encephalopathy occurred in 6 shunt patients at 19 months (3-40 months). The late re- bleeding rates of shunt patients and disconnection pa- tients were 8.1% (3/37 patients) and 14. 9 % (9/ 61) (P>0. 05) respectively. The late encephalopathy rates of shunt patients and disconnection patients were 16. 2% (6/37) and 0% (0/61) respectively (P <0. 01). Eight patients (5. 5 %) died of upper gas- trointestinal bleeding (2), hepatic failure (3), liver cancer (2), and rectal cancer (1) in the period of follow-up. C

Dear Editor,Zika virus（ZIKV）used to be an unknown mosquito-borne flavivirus,and maintained its limited sylvatic circulation in a few African and Asian countries（Enfissi et al.,2016）.Based on available clinical data,the symptoms in human infections with ZIKV are supposed to be similar to other arbovirus infections such as dengue,and characterized by fever,skin rashes,conjunctivitis,muscle and joint pain,malaise,and headache（Duffy et al.,2009）.

Selective modification of peptides has always been a challenging issue. The selective alkylation of peptides can alter the biological activity and physical properties of molecules, and it has gained significant research interest. We herein disclose an intriguing gold-catalyzed alkylation of peptides using bench-stable unactivated alkyl bromides under photoredox catalysis. A wide range of structurally diverse primary, secondary and tertiary alkyl bromides serve as effective coupling partners to precisely connect with the α-C(sp3)–H in glycine residue of peptides. This protocol demonstrates an exceptionally broad scope for alkyl halides and excellent tolerance for a wide range of useful functional groups. A series of relay transformations to construct cyclic peptides, to proceed click reaction and to realize peptide fluorescence labeling further enhance its synthetic practicality. In addition, mechanistic studies and density functional theory(DFT) calculations reveal an inner-sphere and subsequent outersphere single electron transfer(SET) mechanism.
