Objective To explore the mechanism by which breast cancer-derived LncRNA OIP5-AS1 regulates the migration, invasion, and epithelial-mesenchymal transition of breast cancer cells through the M2 polarization of tumor-associated macrophages (TAM). Methods MDA-MB-231 cells were divided into the control group (blank control), the NC group (transfected with NC siRNA), and the si-OIP5 group (transfected with LncRNA OIP5-AS1 siRNA). The mRNA expression levels of LncRNAs OIP5-AS1, IL-4, and IL-13 were detected by RT-qPCR. The protein expression levels of IL-4 and IL-13 in the culture supernatant were detected by ELISA. The culture supernatant from the control group was added to RPMI 1640 medium at different volume ratios to induce the polarization of M0 macrophages into TAMs. The mRNA expression of CD206 in TAMs was detected by RT-qPCR. M0-type macrophages were induced with the medium supernatant of the NC group/si-OIP5 group, and the expression of CD206 was detected by Western blot. Subsequently, a co-culture model of macrophage and MDA-MB-231 was constructed to evaluate the migration and invasion abilities of MDA-MB-231 cells and detect the expression changes in Vimentin, N-cadherin and E-cadherin. Results Compared with the control and NC groups, the si-OIP5 group showed significantly downregulated expression of LncRNA OIP5-AS1 (P<0.001) and significantly decreased IL-13 mRNA and protein levels (P<0.05). Meanwhile, no significant difference was observed in the expression of IL-4 among the groups. Conditioned medium induced CD206 expression in M0 macrophages in a volume-dependent manner, with the strongest effect at a 40% volume ratio (P<0.001). The CD206 protein level in the si-OIP5 group significantly decreased (P<0.01). In the co-culture system, the migration and invasion abilities of MDA-MB-231 cells in the si-OIP5 group significantly weakened (P<0.001), the expression of E-cadherin was upregulated, and the expression levels of N-cadherin and Vimentin were downregulated (both P<0.01). Conclusion Breast cancer-derived LncRNA OIP5-AS1 can induce TAM M2 polarization mediated by IL-13, thereby promoting the migration, invasion, and EMT of breast cancer cells.

Objective:To investigate the application value of enhanced recovery after surgery (ERAS) in perioperative period of laparoscopic sleeve gastrectomy (LSG).Method:The retrospective cohort study was conducted. The clinical data of 1 181 patients undergoing LSG in the Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from January 2021 to December 2023 were collected. There were 242 males and 939 females, aged (31±8)years. Of 1 181 patients, 598 cases receiving routine perioperative care were divided into the control group, and 583 cases receiving perioperative care with ERAS were divided into the ERAS group. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between the groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney rank sum test was used for comparison between the groups. Count data were expressed as absolute numbers or percentages, and the chi-square test or Fisher exact probability were used for comparison between the groups. Repeated measurement data were analyzed using the repeated ANOVA, with baseline scores as covariates. Simple effects analysis was conducted in case of interaction, and multiple comparisons were adjusted using the Bonferroni method. Results:(1) Postoperative outcomes. The numerical rating scale (NRS) scores for pain at immediate return to the ward and on the third postoperative mornings changed from 5.35±0.93 to 2.57±0.83 in the control group, versus changed from 3.15±0.93 to 0.70±0.65 in the ERAS group, showing significant difference between the two groups ( Ftime=66.58, Fgroup=1 765.85, Finteraction=6.90, P<0.05). After adjusting NRS scores for pain at immediate return to the ward as the baseline, results of simple effects analysis showed that on the third postoperative mornings, the NRS scores in the ERAS group were lower by 1.89, 1.53, and 1.76 respectively compared to the control group ( P<0.05). Cases with nausea at immediate return to the ward and on the third postoperative mornings changed from 497 to 97 in the control group, versus changed from 198 to 11 in the ERAS group, showing signifi-cant difference between the two groups ( χ2=294.45, 398.76,209.39, 73.00, P<0.05). Cases with vomiting at immediate return to the ward and on the third postoperative mornings changed from 243 to 41 in the control group, versus changed from 51 to 2 in the ERAS group, showing significant difference between the two groups ( χ2=160.54, 149.37, 71.76, 35.69, P<0.05). The duration of postoperative hospital stay was (3.22±0.65)days in the control group, versus (2.17±0.49)days in the ERAS group, showing a significant difference between the two groups ( t=-11.89, P<0.05). (2) Complications. The incidence of cases with dehydration within postoperative 30 days was 0.50%(3/598) in the control group, versus 0.69%(4/583) in the ERAS group, showing no significant difference between the two groups ( P>0.05). None of patient in the control group and the ERAS group experienced bleeding, gastric leakage, intra-abdominal infection, and no patient had unplanned secondary surgery within postoperative 30 days. Conclusions:ERAS in perioperative period of LSG are safe and feasible. Compared to routine care, ERAS can significantly reduce postoperative pain, decrease the incidence of postoperative nausea and vomiting, shorten the postoperative hospital stay, and do not increase the rate of postoperative complications or unplanned secondary surgeries within postoperative 30 days.

Objective:To investigate the changes in liver injury and oxidative-antioxidant level in mice exposed to X-rays at varying doses.Methods:Fifty-four 8-week-old male C57BL/6J mice were divided into three groups, namely the control, 2 Gy irradiation, and 4 Gy irradiation groups. Then, each of the groups was further divided by days post-irradiation (i.e., 1, 3, and 7 d), and so nine sub-groups ( n = 6). After irradiation was performed as planned, all the mice were dissected and weighed, and their liver indexes were calculated to determine any histopathological changes in the liver. The peripheral blood cell count and the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were detected. Furthermore, spectrophotometry was also used to determine the superoxide dismutase (SOD) activity, the malondialdehyde (MDA) concentration, and the reduced glutathione (GSH) concentration in liver tissues. Results:Compared to the control group, mice undergoing irradiation exhibited a significant reduction in body weight ( F = 84.03, 27.11, 25.50, P < 0.001), but significantly increased liver indexes ( F = 28.40, 17.75, P <0.001) at 1, 3, and 7 d post-irradiation. Pathological observations of these mice revealed liver injury, which proved related to dose and time course. The counts of leukocytes, neutrophils, and lymphocytes in peripheral blood decreased significantly ( F = 8.42-22.91, P < 0.05), trending downward with an increase in the radiation dose. For mice in the 4 Gy irradiation group, their AST and ALT levels increased significantly at 1 d post-irradiation ( H = 7.24, 7.82, P < 0.05), and their ALP levels rose notably at 1 and 3 d post-irradiation ( F = 11.86, 9.75, P < 0.05). Furthermore, their MDA and SOD levels initially rose and then dropped but their GSH levels exhibited an opposite trend at 1, 3, and 7 d post-irradiation. There was a positive correlation between their MDA levels in the liver and the degree of damage to histopathological lesions at 1, 3, and 7 d post-irradiation ( r = 0.30, P < 0.001). Conclusions:A model for radiation-induced liver injury of mice was preliminarily established in this study. It can be concluded that X-rays at varying doses affect the severity of liver injury, pathological grade, peripheral blood cell count, liver function index, and liver oxidative and antioxidant levels of mice, presenting a certain relationship between dose and time course effects.

Attention deficit hyperactivity disorder is a common neurodevelopmental disorder characterized by persistent attention deficit, hyperactivity, and impulsive behaviors that are not consistent with developmental age.Academic and vocational difficulties, social exclusion, and delinquent behaviors are manifested in daily life.It is also commonly accompanied by psychiatric problems.At the same time, mental problems are common, and the overall quality of life is greatly affected, placing a heavy burden on society as well as the family.International attention deficit hyperactivity disorder experts have developed a common and comprehensive International Classification of Functioning, Disability and Health core set of classifications for assessing individual functioning in attention deficit hyperactivity disorder.

Objective To investigate the effects of lowdose ionizing radiation (LDIR) on oxidative stress and damage repair in human bronchial epithelial (HBE) cells. Methods HBE cells were divided into 0, 50, 100, and 200 mGy groups, and cultured for 24 and 48 h after X-ray irradiation, respectively. The cell viability, levels of glutathione (GSH), malondialdehyde (MDA), and 8-hydroxy-2’-deoxyguanosine (8-OHdG), and transcriptional levels of DNA damage repair genes PPP2R2D and TP53 were measured. Results At 24 h after irradiation, there was no significant difference in the cell viability between the dose groups and the control group (P > 0.05); all dose groups had significantly increased MDA level, dose-dependently decreased GSH level, dose-dependently increased 8-OHdG level, and significantly increased mRNA level of PPP2R2D gene (all P < 0.05); the mRNA expression level of TP53 gene was significantly increased in the 50 mGy group (P < 0.05). At 48 h after irradiation, there were the highest cell viability, significantly decreased MDA and 8-OHdG levels, and significantly increased mRNA expression levels of PPP2R2D and TP53 genes in the 50 mGy group compared with the control group (all P < 0.05); the GSH level in the 100 mGy group was significantly increased (P < 0.05). Conclusion LDIR, especially radiation at 50 mGy, can affect the oxidative-antioxidant level in HBE cells and the transcript-level differential expression of DNA damage repair genes.

Background The thyroid gland is one of the organs sensitive to ionizing radiation, and there are few studies on the effects of long-term exposure to low doses of ionizing radiation on the thyroid gland of radiation workers. Objective To investigate thyroid abnormalities in workers in medical radiology departments in Guangdong Province and to identify potential influencing factors of thyroid abnormalities. Methods A total of 1657 radiation workers from 48 hospitals in Guangdong Province were selected as survey subjects using convenience sampling, and their personal dose monitoring results and health examination information were retrospectively analyzed to determine the factors affecting thyroid abnormalities. Results The M (P₂₅, P₇₅) of thyroid absorbed dose (D_T) was 1.55 (0.65, 3.96) mGy in the 1657 investigated workers. The attribute-specific medians of D_T were 1.29, 1.38, 1.99, and 3.51 mGy for departments of diagnostic radiology, interventional radiology, radiotherapy, and nuclear medicine, respectively; and 1.10, 1.55, and 1.80 mGy for job titles of nurse, technician, and physician, respectively. Differences in D_T by gender, age, years of radiological work, age of radiation exposure onset, occupational category, and job title were statistically significant (Z=−6.35, H=708.52, 918.20, 31.19, 95.64, 39.28, P<0.05). The positive rate of thyroid abnormalities in investigated workers was 46.53% (771/1657). Among them, the positive rate of abnormal thyroid function was 22.87% (379/1657), that of abnormal thyroid morphology was 33.98% (563/1657), and that of thyroid nodule was 26.55% (440/1657). The differences in thyroid abnormality rates by gender, age, years of radiation work, age of radiation exposure onset, D_T, and job title of radiation workers were statistically significant (χ²=51.89, 49.64, 20.54, 18.29, 12.07, 16.16, P<0.05). The differences in abnormal thyroid function positive rate by gender, age of radiation exposure onset, and job title were statistically significant (χ²=26.21, 6.21, 8.32, P<0.05). The differences in the positive rates of abnormal thyroid morphology and nodules were statistically significant by gender, age, years of radiological work, age of radiation exposure onset, D_T, and job title (abnormal thyroid morphology, χ²=40.24, 64.17, 37.63, 15.17, 19.28, 15.05; nodules, χ²=31.41, 77.98, 42.11, 19.16, 21.70, 13.52, P<0.05). The positive rates of thyroid abnormality, thyroid morphology abnormality, and nodules all showed a linear increasing trend with increasing age, years of radiation work, and age of radiation exposure onset (P<0.05). The results of logistic regression analysis indicated that the factors influencing thyroid abnormalities were female (OR=2.17, 95%CI: 1.72-2.74), increased years of radiological work (OR=1.04, 95%CI: 1.03-1.06), onset of radiation exposure in age groups of 30-34 and ≥35 years (OR=1.63, 95%CI: 1.12-2.37; OR=2.58, 95%CI: 1.74-3.29), and working in department of diagnostic radiology (OR=1.40, 95%CI: 1.07-1.84). Conclusion Long-term exposure to low doses of ionizing radiation has an effect on thyroid abnormalities in medical radiation workers. Among them, being female, physicians, and working in department of diagnostic radiology are at a higher risk of abnormal thyroid function; being female, increased years of radiation work, and radiation exposure onset at age ≥30 years are associated with a higher risk of reporting abnormal thyroid morphology.
