AIM: To observe the mRNA expressions of Insulin-induced gene 2(Insig-2) and Vitamin D receptor(VDR) in HepG2 cell line and investigate the possible mechanism of berberine on regulating blood lipid. METHODS: HepG2 cells were incubated with Bet at different concentrations(1,3,10,30,100 ?mol/L),and incubated with 3 ?mol/L berberine for various times(0,12,24,48,72 h).Total RNA was extracted and the mRNA expressions of Insig-2 and VDR from HepG2 cells treated by berberine were quantified by RT-PCR.(RESULTS): After exposure to gradient concentrations of berberine for 24 h,the mRNA expressions of Insig-2 and VDR in HepG2 cells increased obviously peaked at 3 ?mol/L concentration,then the up-regulating effect declined gradually.The relative coefficient between them was(0.753)(P

Objective To explore the value of the plasma miR-193a-5p level on diagnosis and monitoring the response to treatment in acute myeloid leukemia (AML). Methods Peripheral blood samples were obtained from AML patients enrolled in hematology department of the Second Hospital of Shanxi Medical University from July 2015 to December 2015, including 30 de novo AML patients, 9 patients in complete remission (CR) and 6 patients in relapse. Peripheral blood samples from 15 healthy people were randomly choosed as the health control group. Plasma miR-193a-5p expression levels were detected by using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results The plasma miR-193a-5p relative expression level of AML patients group [0.465 6 (0.103 1-5.000 2)] was obviously lower than that of health control group [0.766 1 (0.052 1-3.134 4)] (U= 122, P= 0.018 7). The plasma miR-193a-5p relative expression levels of de novo group and relapse AML group were significantly lower than those of CR group and health control group (P<0.05), and there was no significant difference between the CR group and health control group (U= 56, P= 0.511 9). No significant correlation was found between the plasma miR-193a-5p level and age, gender, blast percentage of the bone marrow, peripheral blood leukocyte count, platelet count, CD34+cells'percentage and so on. Conclusion The decreased plasma miR-193a-5p expression level can be served as a new and noninvasive biomarker for the evaluation of diagnosis and treatment in AML.

Objective To investigate the methylation status of ZIC1 gene in peripheral blood and lung cancer tissues of NSCLC patients and its prognostic significance. Methods We took the peripheral blood, cancer tissues and adjacent tissues of 95 NSCLC patients. The peripheral blood of 95 healthy people was taken as control group. MSP was used to compare the detection rate of ZIC1 methylation between peripheral blood and cancer tissues. And we analyzed the correlation of ZIC1 methylation in peripheral blood and cancer tissues with the clinicopathological factors of NSCLC patients. Results The methylation detection rates of ZIC1 in peripheral blood and lung cancer tissues in NSCLC patients were significantly higher than those in peripheral blood of healthy people and adjacent tissues of NSCLC patients (P < 0.05), and the sensitivity and specificity of ZIC1 methylation in the diagnosis of tumor tissues were higher. The positive rate of ZIC1 gene methylation in peripheral blood and tumor tissues of NSCLC patients was significantly correlated with tumor diameter, metastasis, stage and pleural effusion (P < 0.05). Conclusion The methylation of ZIC1 gene is related to the occurrence, development, metastasis and stage of NSCLC. It may be used as a diagnostic and prognostic indicator of NSCLC.

Objective:To summarize the best evidence for the prevention of medical device related pressure injuries in patients in ICU, and to provide a basis for clinical nursing practice.Methods:Using evidence-based method and computer 6S evidence model, the relevant literature was retrieved. The resource types included clinical guidelines, evidence summaries, systematic reviews and expert consensus. The retrieval time was from the establishment of the databases to January 2021. Three researchers who received evidence based nursing training independently evaluated various types of literature, and extracted evidence from literature that met inclusion criteria.Results:A total of 11 articles were included with 8 guidelines, 1 systematic review, 1 evidence summary, and 1 expert consensus. The 24 best evidences related to risk assessment, skin assessment and cleaning, selection and wearing of medical devices, preventive use of dressings, and education and training were summarized.Conclusions:This study summarized the clinical practice basis for the prevention of medical device related pressure injuries in patients in ICU, which can provide scientific and effective theoretical guidance for clinical nursing staff to implement changes in practice. And it is recommended that the evidence should be combined with the clinical reality when using evidence. Analyze the facilitating factors and obstacles in the process of using evidence and formulate reform strategies suitable for clinical transformation, and then apply them to daily clinical work to improve the quality of nursing work.

Purpose The incidence and drug resistance rate ofAcinetobacter baumannii pneumonia are becoming more and more serious.To summarize the computed tomography (CT) appearance ofAcinetobacter baumannii pneumonia and to provide evidence for early clinical diagnosis and treatment.Materials and Methods The imaging findings of 49 patients with sputum culture confirmed Acinetobacter baumannii pneumonia were retrospectively analyzed,and the imaging features were summarized.Results The three most common patterns of chest CT findings in Acinetobacter baumannii pneumonia were ground-glass opacification (69.4％,34/49),consolidation (67.3％,33/49),and pleural effusion (53.1％,26/49).While,the most common patterns of chest X-ray were pulmonary plaque (83.7％,41/49),consolidation (36.7％,18/49),and pleural effusion (36.7％,18/49).Further analysis showed that there was no statistically significant difference in the CT and X-ray findings between combined infection of Acinetobacter baumannii with other pathogens and single Acinetobacter baumanniizxcvbnm,infection (P＞0.05).Conclusion The three most common changes of chest imaging of Acinetobacter baumannii pneumonia are ground-glass opacification,pulmonary consolidation and pleural effusion.It is of great significance to summarize its imaging features for early diagnosis,treatment and prognosis-predicting.

OBJECTIVETo identify the MPL L391-V392ins12 spliceosome and analyze its frequencies in patients with myeloproliferative neoplasms (MPN).

METHODSMPL aberrant spliceosome was identified through reverse transcription polymerase chain reaction (RT-PCR)combined with cloning sequencing. The mutation of this spliceosome in 248 MPN patients and 200 normal people was determined by allele-specific polymerase chain reaction (AS-PCR).

RESULTSA novel aberrant spliceosome of MPL gene (MPL L391-V392ins12)was identified, i.e. 36 bp intron was retained between exon7 and exon8, and there were 12 amino acids (EGLKLLPADIPV)inserted. MPL L391-V392ins12 mutation was detected in 19 (7.66%)of the 248 patients with MPN, including 1 (1.92%) of 52 patients with PV, 14 (9.66%) of 145 with ET, and 4 (7.84%) of 51 with PMF. And the mutation was not detected in the group of 200 normal people.

CONCLUSIONMPL L391-V392ins12 spliceosome is an aberrant spliceosome present in the MPN. It can be detected in PV, ET and PMF, and more frequently in ET and PMF. This mutation may play an important role in the process of MPN.
