Since the publication of a high-throughput DNA sequencing technology based on PCR reaction was carried out in oil emulsions in 2005, high-throughput DNA sequencing platforms have been evolved to a robust technology in sequencing genomes and diverse DNA libraries. Antibody libraries with vast numbers of members currently serve as a foundation of discovering novel antibody drugs, and high-throughput DNA sequencing technology makes it possible to rapidly identify functional antibody variants with desired properties. Herein we present a review of current applications of high-throughput DNA sequencing technology in the analysis of antibody library diversity, sequencing of CDR3 regions, identification of potent antibodies based on sequence frequency, discovery of functional genes, and combination with various display technologies, so as to provide an alternative approach of discovery and development of antibody drugs.

Objective To investigate the portal vein embolization (PVE) and portal vein ligation (PVL) in liver regeneration of rats with hepatic fibrosis.Methods Fifty rats with liver fibrosis were prepared,including 10 rats were randomly chosen as pre-operative control group.The other 40 rats were divided into two groups:PVE group (A1,n =20) and PVL group (A2,n =20).We chose to embolize and ligate the right portal vein,respectively.The blood samples were obtained at different end points for measuring ALT and AST levels.Each liver lobes and whole liver were weighed,and non-embolized liver lobe/whole liver weight ratio,non-ligated liver lobe/whole liver weight were caculated at different end points.The samples from liver with/without embolization or ligation were were stained with hematoxylin-eosin,and the changes of microstructure of liver were observed.Immunostained for PCNA and Ki-67 were performed.Results Transient elevation of postoperative ALT and AST levels were noted in each group.Serum ALT and AST reached the peak on the first day in both of PVE and PVL groups [ALT,A1 (66.5 ±6.3) U/L vs(491.5 ± 48.0) U/L,A2 group(62.8 ±5.7) U/L vs(433.7 ±41.0) U/L;AST,A1group (113.4 ± 12.5) U/L vs (685.2 ±65.7) U/L,A2 group (110.4 ± 11.1) U/L vs(623.9 ±75.2) U/L,P＜0.05),and started to decrease on the third day,recovered to the pre-operative level on the fourteenth day (P ＞ 0.05).The weight percentage of non-embolized and non-ligated liver lobes/whole liver after PVE and PVL increased.There was no significant difference between the first day and pre-operative levels (P ＞ 0.05).Nevertheless,there were significant differences observed from the third,seventh,fourteenth days (A1 group,50.2 ± 5.0,57.7 ±5.7,61.8 ±6.6;A2group,49.6 ±3.5,55.7 ±6.9,63.0±5.1,respectively)compared with preoperative groups (A1 group,34.4 ± 4.0;A2 group,34.4 ± 4.0) (P ＜ 0.05).There was no significant difference between group A1 and A2 in each time point (P ＞0.05).The PCNA and Ki-67 were positive in hepatocytes and increased after operation,reached the peak in the third day (P ＜ 0.05),decreased slowly and restored to the normal level in the fourteenth day after operation,meanwhile,there was no significant difference between group A1 and A2 (P ＞ 0.05).Conclusions Fibrosis rats had the ability of regeneration in the contralateral part of the liver after selective PVE and PVL and there was no significant difference on the proliferative degree.Therefore,the safety and reliability of PVE and PVL in inducing liver regeneration in rats with liver fibrosis were confirmed.

OBJECTIVETo discuss the operation method and characteristic of correcting upper eyelid depression by transposition of orbital septum fat.

METHODSDuring the double eyelid surgery, we set.the lateral orbital septum fat completely free, while the bottom is still connected with the middle orbital septum fat. We separate a tunnel from the middle to the inner side in orbital septum, and the separated orbital septum fat is transposed to the inner side of orbital septum by the tunnel with suturing fixation.

RESULTSFrom March 2008 to October 2013, 51 cases with upper eyelid depression were treated successfully. Patients were followed up for 3 months to 3 years (average, 7. 5 months) with sustained aesthetic results.

CONCLUSIONSOrbital septum fat transposition can successfully correct the upper eyelid depression. It should become a regular procedure in blepharoplasty.

Objective:To implement PRECEDE-PROCEED based intervention in community patients with type 2 diabetes mellitus (T2DM) and explore its effects on patients' diabetes knowledge and self-efficacy.Methods:Totally 86 T2DM patients treated in a community health service center in Hangzhou between May and October 2014 were selected using convenient sampling and divided into intervention group ( n=43) and control group ( n=43) . Patients in the intervention group received 6-month intervention based on PRECEDE-PROCEED, while patients in the control group received a regular community health education course once during the same period. The diabetes knowledge and self-efficacy scores were evaluated between the two groups before and 3 and 6 months after intervention. At last, a total of 40 patients in the intervention group and 42 patients in the control group completed the study. Results:Repeated measures analysis of variance showed that there were time-dependent, between-group and combined effects in diabetes knowledge and self-efficacy scores in the two groups ( P<0.05) . Pairwise comparison between the two groups revealed that there was no statistically significant difference in diabetes knowledge and self-efficacy scores between the two groups before intervention ( P>0.05) , but there were statistically significant differences in diabetes knowledge and self-efficacy scores between the two groups 3 and 6 months after intervention ( P<0.05) . Conclusions:The PRECEDE-PROCEED based intervention can effectively improve the diabetes knowledge and self-efficacy of T2DM patients, which is worth promoting in clinical practice.

OBJECTIVE: To detect pathogenic variants in a pedigree affected with propionic acidemia (PA). METHODS: The proband was subjected to high-throughput next-generation sequencing. Suspected variants were validated by Sanger sequencing of his family members. mRNA was extracted from peripheral blood lymphocytes from the proband's father in order to verify the impact of the splicing variant by RT-PCR combined with Sanger sequencing. The pathogenicity of the missense variant was predicted by using PolyPhen-2, Mutation Taster, SIFT, COBALT and HOPE software. RESULTS: The proband was found to harbor compound heterozygous variants of the PCCB gene, namely c.184-2A>G and c.733G>A (p.G245S), which were respectively inherited from his father and mother. RT-PCR combined with Sanger sequencing confirmed skipping of exon 2 during transcription. Bioinformatic analysis indicated the c.733G>A (p.G245S) variant to be damaging. CONCLUSION The two variants of the PCCB gene probably underlay the disease in this patient. Above findings have enriched the spectrum of PCCB gene variants.

Objective:To evaluate the detection ability of two kinds of high-throughput method to determine neutralizing antibodies based on a microneutralization test (MNT).Methods:Serum samples were collected from the early phase and follow-up period (117 samples in total) for neutralizing antibody testing. They were tested using MNT, pseudovirus neutralization assay (PBNA), competitive inhibition assay (including enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay (CLIA)) to evaluate the correlation coefficients and threshold values for the effectiveness of these high-throughput neutralizing antibody assays.Results:The correlation coefficients for PBNA, ELISA, and CLIA relative to MNT were 0.760, 0.778, and 0.725, respectively, for individuals infected with 2019-nCoV. The area under the ROC curve was 0.901 for a cutoff value of 50 for the PBNA assay, 0.934 for a cutoff value of 1∶8 for the ELISA assay and 0.838 for a cutoff value of 1.28AU/ml for the CLIA assay when the threshold value for the microneutralization test was taken as 1: 10 (less than 1: 10 is considered negative).Conclusions:The high-throughput method for the detection of COVID-19 neutralizing antibodies are scientific and feasible, and provide an important technical tool for the regular prevention and control of the epidemic.
