Objective: The existence of activating transcription factor 1 (ATF1) could be employed as a clinical marker in the context of cervical cancer development, although its specific mechanism has not been fully clarified. Methods: To evaluate the presence of ATF1, miR-630, and myelin and lymphocyte protein 2 (MAL2) in cervical malignancies, we conducted quantitative reverse transcription polymerase chain reaction, immunohistochemistry, and Western blot assays; further studied the expansion, migration, invasion and epithelial-mesenchymal transition (EMT) of cervical carcinoma cells using colony formation assay, transwell, loss cytometry, Western blot.Chromatin immunoprecipitation (ChIP) and RNA immunoprecipitation (RIP) were used to verify that ATF1 could directly transcriptionally repress miR-630; dual luciferase reporter assay and RIP assay were employed to confirm that miR-630 targeted to repress MAL2. Results: In cervical cancer cases, elevated ATF1 expression and reduced miR-630 expression were detected, displaying a negative relationship between them. Inhibition of ATF1 hindered the growth, migration, infiltration, and EMT in cervical carcinoma cells, while upregulation of miR-630 mitigated the aggressive characteristics of these cells. ATF1 was found to transcriptionally repress miR-630 by TransmiR and ALGGEN prediction and ChIP validation.MicroRNA modulates gene expression and affects cancer progression, and we discovered that miR-630 regulates cancer progression by targeting and inhibiting MAL2. Conclusion ATF1, which modulates the miR-630/MAL2 pathway, affects the EMT process and cervical carcinoma cell growth and spread. Therefore, ATF1 may serve as a promising marker and treatment target for cervical malignancies intervention.

ObjectiveTo explore the effect of motor imagery (MI) on knee function after unicompartmental knee arthroplasty (UKA). MethodsFrom January to September, 2022, 32 patients underwent UKA for the first time in Xuanwu Hospital were randomly divided into control group (n = 16) and experimental group (n = 16). All the patients accepted routine rehabilitation, and the experimental group accepted MI in addition, until four weeks after discharge. They were assessed with Oxford Knee Score (OKS), Visual Analogue Scale for pain (VAS), range of motion (ROM) of knee, and Timed Up and Go Test (TUGT) before and after treatment. ResultsAll the indexes improved after treatment (|t| > 2.517, P < 0.05), except ROM in the control group; and they improved more in the experimental group than in the control group (F > 7.999, P < 0.01), except the VAS score. ConclusionMI can further improve the knee function after UKA, but do less for pain.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To study the correlation between occupational radiation exposure and chronic metabolic diseases.Methods:The status of chronic metabolic diseases of medical workers were compared in 5 hospitals in Hangzhou. As representatives of chronic metabolic diseases, diabetes and metabolic syndrome (MS) were compared in association with duration of radiation exposure.Results:Long-term ionizing radiation (IR) exposure was led to increased blood pressure, fasting blood glucose (FBG) , dyslipidemia, gallbladder disease, and MS. The years of radiation exposure was associated with lens opacity, gallstone and MS in men and gallbladder polyps in women. Radiation working more than 10 years is one of the independent risk factors for increased FBG and MS. Moreover, the risk of FBG increase in the group of radiation working more than 10 years was 3.052 times of that the non-exposed group, and the risk of MS occurrence was 4.132 times that of the non-exposed group.Conclusion:Long-term exposure to IR increases the risk of chronic metabolic diseases.

Objective:To construct a hypoglycemia nursing information system and explore its application effects in the nursing quality management of the Department of Endocrinology.Methods:Based on the existing blood glucose information management system of Peking University First Hospital, a hypoglycemic nursing information system with evaluation, alarm, record, remind, and management functions was designed. We compared the number of cases of standardized correction of hypoglycemia in inpatients by nurses, the complete and accurate cases of hypoglycemia records, and the monthly time spent on the quality control by nursing special managers before the application of the system (from February to December 2017) and after the application (from January 2018 to December 2019) .Results:After the application of the hypoglycemia nursing information system, the complete and accurate cases of hypoglycemia records, and the cases of standardized correction of hypoglycemia were statistically different from those before the application of the system ( P<0.001) . The quality control time of nursing special managers decreased from (7.55±1.01) hours a month to (0.41±0.21) hours a month. Conclusions:Application of the hypoglycemia nursing information system adapts to the hospital's management requirements for hypoglycemia, which not only promotes the standardization of nurses' handling of hypoglycemia events, improves the completeness and accuracy of written records, but also saves time for managers to perform the quality control and promotes the scientific and digitalization of nursing special management.

Objective: To analyze the clinical features and factors associated with osteonecrosis in children with systemic lupus erythematosus (SLE). Methods: A retrospective analysis of 15 SLE patients with osteonecrosis in Department of Pediatrics, Renji Hospital Affiliated to School of Medicine of Shanghai Jiaotong University from January 2013 to May 2017 was carried out.Forty-two SLE patients without osteonecrosis were selected as control group.The clinical, laboratory variables and the treatment were compared among SLE patients who were with and without osteonecrosis. Results: (1) Fifteen patients developed osteonecrosis that constituted 8.6% of all the 175 hospitalized SLE patients during the same period.(2) Of 15 patients, 2 patients were male, 13 patients were female, who developed osteonecrosis with an average age of (13.9±2.7) years (range: 10-18 years old). The duration of SLE before the diagnosis of osteonecrosis ranged from 6 days to 141 months, the median was 10 months, and 80.0% (12/15 cases) was diagnosed with osteonecrosis within 2 years of SLE diagnosis.There were 36 joints involved in 15 patients, all of which were detected by magnetic resonance imaging(MRI). The knees were the most commonly involved joints(14/15 cases, 93.3%), followed by hip and ankle joints.(3) Univariate analysis revealed that the level of Triglyceride [(2.080±1.500) mmol/L vs.(1.350±0.945) mmol/L], maximum daily dose of glucocorticoid[(1.25±0.33) mg/kg vs.(1.07±0.22) mg/kg], positive rate of gene associated with glucocorticoid-induced osteonecrosis of femoral head(100.0% vs.54.8%)were significantly higher in SLE with osteonecrosis than those in controls(all P<0.05). While the level of 25(OH)D₃[(21.37±11.29) μg/L vs.(31.45±17.73) μg/L] was significantly lower than that of controls(P<0.05). Multiple factor Logistic regression analysis showed that hypertriglyceridemia and daily maximum dose of glucocorticoid were the risk factors for osteonecrosis. Conclusions Osteonecrosis mostly occurred in children over 10 years old, knee joint involvement is the most common.The high-risk time of osteonecrosis is within 2 years of SLE diagnosis.Hypertriglyceridemia and daily ma-ximum dose of glucocorticoid are risk factors associated with osteonecrosis in children with SLE.
