The microcirculatory perfusion of liver, spleen, kidney, small intestine andtail were measured by a laser doppler flowmeter after intravenous injection of agkistro-don antithrombotic anzyme (0. 05 U, 0. 025 U/100 g B. W.) in 40 hemorrhagic shockrats and 15 hemorrhagic rabbits. The results showed that 5～20 min after injection therenal perfusion increased significantly, but there was no marked increase of renal arteryblood flow when it was simultanously detected with a electromagnetic flowmeter, thoughthe urine was increased. Authors suggested that Svate may have decreased the resistenceof renal microcirculation and accelerate the veosity of renal microcirculation, thus theyincreased the microcirculatory perfusion in renal cortex.

With the rapid development of genome sequencing technologies, a large amount of prokaryote genomes have been sequenced in recent years. To further investigate the models and functions of genomes, the algorithms for genome annotations based on the sequence and homology features have been widely implemented to newly sequenced genomes. However, gene annotations only using the genomic information are prone to errors, such as the incorrect N-terminals and pseudogenes. It is even harder to provide reasonable annotating results in the case of the poor genome sequencing results. The transcriptomics based on the technologies such as microarray and RNA-seq and the proteomics based on the MS/MS have been used widely to identify the gene products with high throughput and high sensitivity, providing the powerful tools for the verification and correction of annotated genome. Compared with transcriptomics, proteomics can generate the protein list for the expressed genes in the samples or cells without any confusion of the non-coding RNA, leading the proteogenomics an important basis for the genome annotations in prokaryotes. In this paper, we first described the traditional genome annotation algorithms and pointed out the shortcomings. Then we summarized the advantages of proteomics in the genome annotations and reviewed the progress of proteogenomics in prokaryotes. Finally we discussed the challenges and strategies in the data analyses and potential solutions for the developments of proteogenomics.

BACKGROUND: Human leukocyte antigen-E (HLA-E) is one of non-classical HLA class I genes. Up to now, the polymorphism analysis is mainly aimed at the variation in exon 3 of HLA-E, which determines HLA-E*01:01 or HLA-E*01:03. However, the identification of the full-length HLA-E and its novel alleles is rare reported.OBJECTIVE: To establish the method of identification of HLA-E genomic full-length sequence, and to identify its novel alleles in healthy blood donors in Shenzhen, China.METHODS: Peripheral blood DNA samples were extracted from the subjects, and the amplified primers and sequencing primers in conserved regions were designed according to the sequences of HLA-E published in the IMGT/HLA database.A high-fidelity reaction system was used to amplify the genomic full-length of HLA-E, followed by sequencing,assembling, confirming and typing.RESULTS AND CONCLUSION: Herein, we successfully established the method for amplifying genomic full-length sequence and sequence-based typing. Two novel HLA-E alleles were nominated by WHO HLA Nomenclature committee as HLA-E*01:01:01:06 and HLA-E*01:01:01:07. Compared with the most related allele HLA-E*01:01:01:01,HLA-E*01:01:01:06 had one nucleotide change at nt-26(G->T) in 5'-promoter, and HLA-E*01:01:01:07 had one nucleotide change at nt3345(T->C) in 3'-UTR. The polymorphism data of genomic full-length HLA-E in Chinese individuals need to be filled, and the method we developed here supplies the key technique for the further studies.

Objective To explore the clinical characteristics of eosinophilic gastroenteritis. Methods The clinical data of 2 children with eosinophilic gastroenteritis was retrospectively analyzed. Results Eosinophilia was found in both cases and path-ological examination indicated eosinophil infiltration in intestinal mucosa. The clinical symptoms were improved after hypoaller-genic diet, amino acid formula and anti-allergy treatment. Conclusions Eosinophilic gastroenteritis is characterized by eosino-phil infiltration with unknown pathogenic factor leading the treatment of eosinophilic gastroenteritis lacking of sound evidence.

Objective:To evaluate the clinical significance of pattern visual evoked potential (P-VEP) parameters on amblyopic patients with normal-vision atfer pleoptic therapy. Methods:We investigated 60 amblyopic children (8-12 years old) who gained normal-vision atfer pleoptic therapy. hTese patients were assigned to a unilateral amblyopia group (40 patients)and a bilateral amblyopia group (20 patients). Another 20 healthy children served as a control group. All patients underwent a full initial ophthalmologic and orthoptic evaluation. P-VEP test was performed in all. Amplitude and latencies were analyzed and compared among groups. The latencies of P100 waves in the amblyopic eyes were used to generate a multiple linear regression formula from sex, ifrst treatment age, baseline visual acuity, and cycloplegic refraction. Results:hTere was no signiifcant difference in the mean levels of best-corrected visual acuity among groups (P>0.05). A signiifcant prolongation of the latency and a decrease of amplitude of P100 waves were observed in the unilateral amblyopia group and the bilateral amblyopia group compared with the healthy control group (P<0.05). Amplitude and latencies of the fellow eyes in the unilateral amblyopia group were abnormal compared with the healthy control group (P<0.05). Multiple linear regression analysis revealed that the latencies of P100 waves were signiifcantly correlated with the ifrst treatment age, baseline visual acuity, and cycloplegic refraction (R2=0.52, P<0.05). Conclusion:Deifcits exist in the fellow eyes and in normal-vision eyes atfer pleoptic therapy. hTe delayed P100 latency is affected by the ifrst treatment age, baseline visual acuity, and cycloplegic refraction. Traditional amblyopic therapy may be not enough for vision function recovery.

Objective:To study the effect of early nursing intervention to prevent lymphedema of upper limb after breast cancer surgery and its effect on postoperative quality of life.Methods:Between July 2018 and March 2020, one hundred and seventeen cases of breast cancer, all female, admitted to department of thyroid and breast surgery, the affiliated Zhongshan hospital of Dalian University, were underwent modified radical mastectomy with axillary lymph node dissection. Fifty-eight cases were included in the control group whereas fifty-nine cases were in the intervention group. The control group received conventional nursing, the intervention group added early care intervention measures on the basis of conventional nursing. Follow-ups were carried out monthly in a period of 9 months post-surgery. The incidence and grade of lymphedema were compared between the two groups.Results:The incidences of lymphedema at 1,3,9 months after surgery were 8.5% (5/59), 8.5% (5/59), 10.2% (6/59) in the intervention group, which were lower than 31.0% (18/58), 36.2% (21/58), 43.1% (25/58) in the control group. Statistics showed significant difference between the two groups ( χ2 value was 9.425, 13.041, 16.289, P<0.05). The incidence of mild, moderate, and severe lymphedema were statistically different between the two groups ( χ2 value was 10.350, 12.078, 17.422, P<0.05). Follow-up for the quality of life was assessed using a 5-dimension evaluation method, including physical status, social/family status, emotional status, functional status and additional attention. One month follow-up showed 20.36±1.80, 20.03±1.68, 34.63±3.52, 15.86±1.96, 19.81±1.04 in the intervention group, all higher than the control group 17.03±1.36, 17.10±1.46, 19.38±1.51, 10.91±1.22, 18.36±1.21. Three-month follow-up showed 23.56±2.72, 23.73±2.20, 39.93±4.17, 20.31±3.04, 26.37±2.23 in the intervention group, higher than those of the control group 20.90±2.14, 19.12±2.63, 25.79±3.59, 13.97±2.67, 21.02±2.50. Nine month follow-up showed 27.44±2.01, 25.80±1.85, 40.88±3.72, 21.02±2.78, 27.02±2.45 in the intervention group, which were high than the control group 19.93±1.66, 20.67±1.46, 19.38±2.29, 16.33±2.65, 22.29±2.52. The difference between the two groups were statistically significant ( t value was 8.691-34.383, P<0.05). Conclusions:Early nursing intervention could prevent lymphedema of upper limb after breast cancer surgery, delay the progress of lymphedema, reduce the incidence and grade of lymphedema, and promote the rehabilitation of patients' affected limbs, improve quality of Life of patients, which is worthy of clinical application.
