The endoscopic assembly (200, 300, 400) includes a proximal hub (210, 310, 410) configured to be selectively engageable with the housing (110) of the handle assembly (100), an elongated shaft (340) extending distally therefrom, an end effector (350) supported at a distal end of the elongated shaft (340), and an inner drive assembly (320) including a proximal portion (323) and a distal portion (325).

Abstract: A method comprising: In some implementations, a method for indexing a multi-layer blockchain system, comprising: A. using, a top layer blockchain, to index a lower layer blockchain by recording a seed node in a transaction log of a block; B. requesting a distributed monitoring cluster to periodically check availabilities of IP addresses and ports that listed in the seed node stored in the top layer blockchain; C. maintaining, for each node in the lower layer blockchain, a separate instance of a global routing table. Each global routing table store entire topological structure of the multi-layer blockchain system, and final consistency of the global routing tables is maintained through a GOSSIP-based data communication protocol. Any node located on the lower layer blockchain described in Step C is configured to access data and services through any one of accessible nodes identified by IP addresses and ports recorded in the global routing table.

Abstract: A method comprising: A. forming a consortium blockchain network using domain network nodes and selecting committee members from top-level domain nodes; B. the committee member who received most votes packs the genesis block and generates a random number; C. the housekeeper having the same number as the random number packs the current block and generates a random number for selecting a next housekeeper to pack the next block, each block is approved by more than half of the committee members; D. during the duty cycle, each housekeeper takes turns packing blocks and generating random numbers and the process is repeated. If a block is not approved, the housekeeper with the next number is requested to repack the block; and E. the last random number generated by a housekeeper before the duty cycle ends is used to select the housekeeper to pack the first block of the next duty cycle.

Abstract: The present invention provides uses of an andrographolide derivative in preparation of a medicament for preventing and treating inflammatory bowel disease. The andrographolide derivative AL-1 has the mechanisms, for the treatment of ulcerative colitis, of scavenging of free radicals, inhibition of NF-?B signaling pathway activation and COX-2 expression, activation of PPAR-? expression, and thus can prevent the transcription and expression of inflammatory-related genes to improve the conditions of inflammation. AL-1 can be used as a medicine for the treatment of inflammatory bowel disease and can be formulated to various dosage forms with a pharmaceutically acceptable carrier.

Abstract: A method for manufacturing a retardation film by using a dual-axial stretching process uses a PMMA to produce a cast film. The cast film is stretched in both a proceeding direction and a width direction simultaneously by 1.0˜5.0 times in both the length and the width. By using a predetermined annealing temperature to co-coordinate shrinking of the film in both directions simultaneously, decrease of the refraction ability caused by the stretching can be controlled. To attain high uniformity of the optical characteristics of the film, the surface temperature of the film during the stretching process is controlled within a predetermined range, then the optical variation thereof is improved, and thus the following optical characteristics are achieved: R0: 0˜3 nm and Rth: ?40˜0 nm; wherein R0=?*?Te+?*?Xe+?*?Ts+?*?Xs+C1 and Rth=a*?Te+b*?Xe+c*?Ts+d*?Xs+C2.
