ABSTRACT
In order to assist in the standardization and maturity evaluation of national hospital information interconnection, and further standardize the application and management of hospital medical record data, a hospital carried out the practice of design of structured medical records and the corresponding quality management from April 2021. Based on the six sigma quality management method, the hospital had developed universal templates for electronic medical records and a list of candidate electronic medical record templates. The problems faced by medical record data had been analyzed, and improvement strategies had been proposed from three levels: template design, software functionality and management services. The clinical departments were guided to design and develop various structured electronic medical record templates for specialties and specialized diseases, and established a medical record template design and quality management method. The hospital had ultimately designed a total of 614 structured electronic medical record templates that met the actual needs of the hospital. This practice enhanced the scalability of structured templates and quality of the data, and achieved localization and specialization of medical record templates while meeting the requirements of information interconnection and sharing, providing reference for promoting the interconnection and sharing of electronic medical records of hospitals in China.
ABSTRACT
Objective:To explore the effect of autologous fat transplantation based on the fine anatomy of the female perineum and aesthetic standards.Methods:From June 2015 to September 2020, 25 female patients with perineal cosmetology requirements in the Department of Plastic Surgery, the Fourth Affiliated Hospital of Harbin Medical University, aged from 28 to 55 years, with an average of 33.7 years. 50-80 ml of the patient＇s autologous fat were collected and filled according to the perineal anatomy and aesthetic standards. Postoperative anti-inflammatory treatment was implemented and sexual life was forbidden for 2 weeks.Results:25 patients were satisfied with the filling effect immediately after operation. Follow-up for 7 days, 1, 3, and 6 months after operation, 20 of 21 cases underwent pudendal filling operation were very satisfied with the postoperative morphology, and 1 case was less satisfied. Among the 20 cases underwent vaginal filling and labia major filling, 17 cases were very satisfied with the postoperative morphology, 2 cases were satisfied after the operation, and 1 case was less satisfied. Of the 10 cases underwent vaginal and G-spot injection, 6 cases were satisfied after the operation. The morphology was very satisfactory, 2 cases were more satisfactory, and 2 cases were less satisfactory. According to a survey of 25 cases of postoperative sexual life satisfaction, 19 cases (76%) had a significant improvement in their conscious sexual life, 3 cases had a more obvious improvement, 1 case had less improvement, and 2 cases had no conscious improvement.Conclusions:The autologous fat injection based on the fine anatomy and aesthetics of the perineum can significantly improve the aesthetic appearance of the perineum.
ABSTRACT
Objective:To predict the expression and molecular regulatory mechanisms of βⅢ-tubulin (TUBB3) in non-small cell lung cancer (NSCLC) using bioinformatics methods.Methods:The GEO profile, TransmiR, miRWalk and ConSite database were employed in the present study. The upstream transcription factor, co-expression gene and the interactive miRNA of TUBB3 were studied to determine the molecular regulatory mechanisms and possible role of TUBB3 in NSCLC.Results:The promoter region of TUBB3 could be recognized by transcription factors associated with NSCLC including Snail and n-MYC and so on. At the post-transcription level, the TUBB3 could be regulated by miRNAs including miR-200 family, miR-342-3p, miR-410 and so on. These miRNAs were associated with proliferation and invasion of NSCLC. TUBB3 was co-expressed with HDGF, GMPS, MRPL9, PMAIP1 and SLBP, and they were co-regulated by the transcription factor Snail. SLBP, PMAIP1 and transcription factor Snail were related to cell cycle and apoptosis.Conclusion:The expression of TUBB3 can be regulated at multiple levels in NSCLC. It may take part in cell cycle and apoptosis regulation in NSCLC, and further influence proliferation and invasion of cancer cells.
ABSTRACT
As the human population ages and the life expectancy increases,tendon injuries will become more prevalent,especially among young individuals.Though the traditional operative therapy for tendon lesion can relieve the suffering of patients,the functional reconstruction is usually not optimistic.Tissue engineering is an advancing field,as the technology of construction in vitro and application in vivo matures,that can provide a more promising approach for tendon repair without tendon autograft.Challenges and future directions in the field of tendon tissue engineering focusing on four key parameters:seed cells,novel scaffolds,and mechanical stimulation.Recently,the discovery of TDSCs (tendon-derived stem cells) provides new ideas for the selection of seed cells and effect of mechanical stimulation on the tendon tissue engineering has become a hot spot.This article provides a review of recent progress in research about seed cells,scaffolds and mechanical stimulation for tendon engineering,and also speculates on the development in the future.
ABSTRACT
BACKGROUND:Semaphorin7A (Sema7A) is a kind of cel surface protein, which can promote the fusion of osteoclasts and the migration of osteoblasts at the same time, affecting the dynamic balance of the bone. It is speculated that Sema7A siRNA may inhibit osteoblast apoptosis induced by titanium particles. OBJECTIVE:To study the effect of Sema7A on the preosteoblast activity inhibited by titanium particles. METHODS:Mouse MC3T3-E1 preosteoblasts at passages 6 and 7 were divided into four groups: in blank control group, MC3T3-E1 cels were cultured alone; in standard control group, cel were cultured with titanium particles; in experimental groups 1 and 2, the cels were cultured with titanium particles+Sema7A overexpression plasmids and titanium particles+Sema7A siRNA, respectively. Apoptotic rate of MC3T3-E1 cels was detected by flow cytometry; the mRNA expression of bone sialoprotein, osteocalcin and type I colagen was detected by Q-PCR; western blot assay was adopted to detect the protein expression of bone sialoprotein, osteocalcin and type I colagen; alizarin red calcium nodule staining was taken to detect the degree of osteoblast mineralization. RESULTS AND CONCLUSION:The expressions of bone sialoprotein, osteocalcin and type I colagen were decreased in the standard control group and experimental group 1, but these expression were significantly increased in the experimental group 2 compared with the standard control group (P < 0.05). Flow cytometry results suggested that the apoptotic rate of osteoblasts in the experimental group 1 was significantly higher than that in the other groups (P < 0.05), and the apoptotic rate in the experimental group 2 was lower than that in the standard control group (P < 0.05). Alizarin red staining showed that there were no obvious mineralized nodules in the experimental group 1, but mineralized nodules formed in the experimental group 2. In brief, the genetic interference technique that inhibits the activity of Sema7A can interfere the process of mouse MC3T3-E1 preosteoblast differentiation inhibited by titanium particles, and thus provide a feasible way for the clinical treatment of wear particles-induced osteolysis using biotechnology.
ABSTRACT
Rheumatoid arthritis ( RA) is a chronic inflammatory disease involving progressive articular damage cause by inflam-matory cells and synoviocytes.Stat3 gene, which is confirmed to play a role in the pathogenesis of RA, regulates the metabolism and apoptosis of the fibroblast-like synoviocytes ( FLS) .SirT1 gene relating to the bone formation was indicated to play a role in the patho-genesis of RA in recent years.This review introduces the pathogenesis and targeted treatment of RA and makes a prediction about the relation between Stat3 and SirT1 gene.We hope it will provide a new direction for the research of RA.
ABSTRACT
Vigilance is defined as the ability to maintain attention for prolonged periods of time. In order to explore the variation of brain vigilance in work process, we designed addition and subtraction experiment with numbers of three digits to induce the vigilance to change, combined it with psychomotor vigilance task (PVT) to measure this process of electroencephalogram (EEG), extracted and analyzed permutation entropy (PE) of 11 cases of subjects' EEG and made a brief comparison with nonlinear parameter sample entropy (SE). The experimental results showed that: PE could well reflect the dynamic changes of EEG when vigilance decreases, and has advantages of fast arithmetic speed, high noise immunity, and low requirements for EEG length. This can be used as a measure of the brain vigilance indicators.

OBJECTIVE:To investigate whether Sema7A siRNA has ainhibitory effect on the osteoclast activation in the process of osteolysis which induced by titanium particles. METHODS:The precursor osteoclasts with the concentration of 4×109 RESULTS AND CONCLUSION:At 7 days of culture, the expression levels of interleukin-1, interleukin-1β, tumor necrosis factor α, matrix metaloproteinase-9 and the receptor activator of nuclear factor-κB in the positive control, /L were seeded on 96-wel plates containing glass cover slips, and divided into four groups: blank control, positive control, experiment and negative control groups. The cel culture medium was added into the control group. 20 μL un-transfected siRNA supernatant was added into the positive control group. 20 μL transfected Sema7A siRNA supernatant was added into the experiment group. 20 μL transfected control siRNA supernatant was added into the negative control group. The supernatant was obtained through the co-culture between titanium particles solution and monocyte-macrophage cel line RAW264.7of mouse for 24 hours. siRNA was transfected into mononuclear macrophage cel lines RAW264.7 of mice. negative control and experiment groups were higher than those in the control group (P < 0.05). The expression level of each factor in the experiment group was lower than that in the positive control and negative control groups (P < 0.05). At 8 days of culture, the proliferation activity of osteoclasts and the number of positive cels stained by tartrate-resistant acid phosphatase in the positive control, negative control and experiment groups were higher than those in the control group (P < 0.05). The proliferation activity of osteoclasts and the number of positive cels stained by tartrate-resistant acid phosphatase in the experiment group were lower than those in the control and negative groups (P < 0.05). These results demonstrate that Sema7A siRNA has a certain inhibitory effect on the osteoclast activation induced by titanium particles.
