The transcript assembly is essential for transcriptome studies trom next-generation sequencing data. However, there are still many faults of algorithms in the present assemblers, which should be largely improved in the future. According to the requirement of reference genome or not, the transcript assembly could be classified into the genome-guided and de novo methods. The two methods have different algorithms and implementation processes. The quality of assembled transcripts depends on a large number of factors, such as the PCR amplification, sequencing techniques, assembly algorithm and genome character. Here, we reviewed the present tools of transcript assembly and various indexes for assessing the quality of assembled transcripts, which would help biologists to determine which assembler should be used in their studies.

Objective:To evaluate the effect of accelerated rehabilitation surgery (ERAS) under diagnosis-intervention packet (DIP) in patients with early cancer of digestive tract undergoing endoscopic submucosal dissection (ESD).Methods:The 64 patients with early cancer of digestive tract treated with ESD in the Gastroenterology Department of the Second People′s Hospital of Jiaozuo were selected by randomized controlled trial and convenient sampling method. According to random number table method, they were divided into routine group and observation group, 32 patients in each group. All patients in the 2 groups paid their medical expenses by DIP method, the routine group was treated with traditional perioperative nursing, and the observation group was treated with ERAS perioperative management mode. The postoperative complication rate, length of hospital stay, DIP allocation ratio, and patient satisfaction with nursing were compared between the two groups.Results:There were 16 men and women in the routine group, 14 men and 18 women in the observation group.After intervention, the incidence of postoperative complications was 21.88% (7/32) in the routine group and 3.12% (1/32) in the observation group, and the difference between the two groups was statistically significant ( χ2=5.14, P<0.05). The length of stay was (10.93 ± 2.87) d in the routine group and (9.01 ± 1.53) d in the observation group, and the difference between the two groups was statistically significant ( t=4.13, P<0.05). The average hospitalization expenses per case was (20 108.23 ± 6 495.49) yuan in the routine group and (18 589.03 ± 4 439.46) yuan in the observation group, and the difference between the two groups was statistically significant ( t=20.57, P<0.05). The DIP allocation ratio of the observation group was 87.98% (303 419.26/344 872.99), and that of the routine group was 69.33% (244 864.99/353 187.65), and the difference between the two groups was statistically significant ( χ2=4.81, P<0.05). The satisfaction of the observation group was 96.88% (31/32) and the routine group was 78.13% (25/32), and the difference between the two groups was statistically significant ( χ2=5.14, P<0.05). Conclusions:The accelerated rehabilitation surgical nursing can effectively reduce the postoperative complications, the average length of stay, the average hospitalization expenses per case under DIP in patients with early cancer of digestive tract treated by ESD, improve the DIP allocation ratio of ESD diseases and the patient′s nursing satisfaction, which reflects the value of nursing work and can be applied to the nursing management of other surgical diseases.
