Objective:To investigate the effects and related mechanisms of long non-coding RNA (lncRNA) AC092295.2 expression on the proliferation and invasion abilities of endometrial cancer cells.Methods:The correlations between AC092295.2 expression level and overall survival (OS) and disease-free survival (DFS) of endometrial cancer patients (180 cases) were analyzed by cBioPortal database (updated in 2022). The miRNA with complementary nucleotide sequences to AC092295.2 was predicted by DIANA Tools sequencing tool. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression of AC092295.2 in human immortalised endometrial epithelial cell line hEEC and human endometrial cancer cell lines (KLE, AN3CA, Ishikawa, HEC-1A). Ishikawa cells with the lowest expression level of AC092295.2 were selected and divided into AC092295.2 overexpression group and control group, which were transfected with pGEX-AC092295.2 plasmid and pGEX-NC plasmid, respectively. qRT-PCR was used to detect the relative expression levels of AC092295.2 and miRNA-200c-3p (miR-200c-3p) in the two groups of cells. Methyl thiazol tetrazolium (MTT) method was used to detect cell viability. Transwell assay was used to detect cell invasion ability. Western blotting was used to detect the expression of proteins related to PTEN-AKT pathway. The dual luciferase reporter gene assay was used to verify the targeting relationship between AC092295.2 and miR-200c-3p.Results:The analysis results of cBioPortal database showed that the OS and DFS of endometrial cancer patients with high expression of AC092295.2 were better than those of patients with low expression (both P < 0.001); the expression levels of AC092295.2 and miR-200c-3p in endometrial cancer tissues were negatively correlated ( r = -0.846, P < 0.001). The results of qRT-PCR detection showed that the relative expression levels of AC092295.2 in endometrial cancer cell lines KLE, AN3CA, Ishikawa, HEC-1A and immortalized endometrial epithelial cell line hEEC were 0.56±0.09, 0.68±0.06, 0.17±0.07, 0.49±0.12 and 0.99±0.11, respectively, and the difference was statistically significant ( F = 35.10, P < 0.001); the relative expression levels of AC092295.2 in Ishikawa cells in the AC092295.2 overexpression group and the control group were 8.92±1.78 and 1.06±0.39, respectively, and the difference was statistically significant ( t = 4.31, P = 0.005). MTT assay results showed that the cell viability of Ishikawa cells in the AC092295.2 overexpression group was lower than that in the control group on days 2, 3, 4, and 5 (all P < 0.05). Transwell assay results showed that the number of invasive Ishikawa cells in the AC092295.2 overexpression group and the control group were 73±4 and 135±14, respectively, and the difference was statistically significant ( t = 4.25, P = 0.005). Western blotting results showed that the relative expression level of phosphatase and tensin homolog (PTEN) protein in Ishikawa cells in the AC092295.2 overexpression group was higher than that in the control group, while the relative expression levels of phosphorylated protein kinase B (p-AKT), Yes associated protein (YAP), murine double mimute 2 (MDM2), and bcl-2-associated death-promoting factor (BAD) proteins were lower than those in the control group. Dual luciferase reporter gene assay and qRT-PCR verified that AC092295.2 targeted negative regulation of miR-200c-3p expression. Conclusions:AC092295.2 is lowly expressed in endometrial cancer cells. Overexpression of AC092295.2 can inhibit the proliferation and invasion abilities of endometrial cancer cells, and its mechanism may be related to the expression of miR-200c-3p-PTEN-AKT signaling pathway.

Objective:To study the correlation between myopia growth and physical development of primary school student in Shihezi area of Xinjiang Uyghur Autonomous Region by measuring the ocular biometry and physical parameters of the eye, and to provide an objective basis for the development of myopia prevention and control.Methods:A cross-sectional study design was used. The Grade 1-6 students from 33 schools in Shihezi area were randomly selected in October 2023. The children were classified according to age into the low age group (6-9 years) and the high age group (10-13 years).The children′s height, weight, axial length (AL), maximum keratometry (steepest keratometry, K1), and minimum keratometry (flattest keratometry, K1) were measured. The body mass index (BMI), keratometric astigmatism (ΔK), mean keratometry (K), corneal radius (CR) and AL/CR were calculated. Correlation analyses were performed between ocular biometry and physical parameters. LASSO regression analysis was used to screen the best variables, and linear regression models were constructed after adjusting for confounding factors of age and sex.Results:A total of 3 986 children aged 6-13 years were included in this study, including 2 094 boys (52.53%) and 1 892 girls (47.47%); 2 162 in the lower age group and 1 824 in the upper age group. Girls had higher K, ΔK and AL/CR values than boys (43.38 D vs 42.7 D, t=-7.84, P<0.01; 1.1 D vs 1.01 D, t=-2.14, P=0.03; 2.97 vs 2.96, t=3.32, P=0.02). Boys had higher AL, height, weight and BMI than girls (23.47 mm vs 23.02 mm, t=13.77, P<0.01; 1.34 m vs 1.33 m, t=3.02, P=0.03; 32 kg vs 29.5 kg, t=7.82, P<0.01; 17.4 vs 16.52, t=10.36, P<0.01). LASSO regression was used to screen the 3 physical parameter variables (height, weight, and BMI) to determine that height was the best physical parameter variable for AL/CR. After adjusting for confounders, it was shown that in the low age group (6-9 years), there was a significant positive correlation between children′s height and AL/CR ( b=0.174, 95% CI: 0.106 to 0.241, P<0.001), whereas in the high age group (10-13 years), there was no correlation between children′s height and AL/CR ( b=0.086, 95% CI:-0.038 to 0.21, P=0.174). Conclusion:There was a positive correlation between height and myopia growth in the lower age group of children in Shihezi area, Xinjiang Uyghur Autonomous Region; there was no correlation between height and myopia growth in the higher age group.

Objective:To compare the efficacy and safety of continuous subcutaneous insulin analogues infusion (CSII) and multiple daily insulin analogues injection (MDII) in fracture patients with type 2 diabetes mellitus (T2MD) during the perioperative period.Methods:The medical data of patients with lower limb fracture complicated with T2MD in Beijing Jishuitan Hospital from 2017 to 2021 were collected by hospital information system and analyzed retrospectively. The medical data of patients extracted included gender, age, body weight, body mass index (BMI), fracture site, pain score and grading, time from fracture to admission, duration of T2MD, laboratory test results at admission, blood glucose control regimen and monitoring result after admission, and the adverse events. Patients were divided into CSII group and MDII group according to blood glucose control regimen during the perioperative period. The clinical features, time to reach target blood glucose range, insulin application, and adverse events in patients of the 2 groups were compared.Results:A total of 207 patients were enrolled in this study, including 90 males and 117 females, aged (61±15) years with BMI of (25.5±3.5) kg/m 2. No significant differences were found in gender, age, BMI, fracture site, pain score and grading, time from fracture to admission, duration of T2MD, and laboratory test resurts at admission in patients between the 2 groups (all P>0.05). Patients in the CSII group had shorter time to reach target range of fasting blood glucose, 2-h postprandial blood glucose, and the both than those in the MDII group [(48.7±30.2) h vs. (78.7±44.5) h, P=0.003; (66.8±31.5) h vs. (93.3±47.6) h, P=0.001; (68.4±30.5) h vs. (96.3±48.1) h, P<0.001]. The total daily dose and total pre-prandial dose of insulin per unit weight in patients when the fasting and 2-h postprandial glucose both reach the target range were less in the CSII group than those in the MDII group [(0.67±0.20) U/kg vs. (0.73±0.17) U/kg, P=0.030; (0.34±0.10) U/kg vs. (0.38±0.09) U/kg, P=0.004]. In 207 patients, hypoglycemia occurred in 17 patients for 23 times with an overall incidence of 8.2%(17/207). The difference in the incidence of hypoglycemia was not significant between the 2 groups [4.9%(5/102) vs. 11.4%(12/105), P=0.319]. None of the 5 patients with hypoglycemia in the CSII group had hypoglycemia for 2 times or more, while 4 of the 12 patients in the MDII group had 2 times of hypoglycemia and 1 had 3 times of hypoglycemia. Other adverse drug events included allergy, systemic edema, nodular hyperplasia of subcutaneous fat, and persistent bleeding at the injection site. Eight patients in the CSII group had other adverse events, including device failure in 5 patients, and using insulin pump during anesthesia, in magnetic field environment, and in humid environment in 3 patients respectively. Conclusions:CSII regimen is helpful for fracture patients with T2DM to achieve target blood glucose range earlier, and provides more ways and opportunities to correct hypoglycemia in patients. However, the insulin pump needs more professional maintenance in practice, so it has limitations to some extent in clinical application.

Objective:To explore application effects of different meibomian gland massage schemes in postoperative treatment of children with chalazion.Methods:Using the convenient sampling method, a total of 280 children with postoperative chalazion who were treated in Ophthalmology Clinic of Beijing Children's Hospital from January to September 2020 were selected as the research objects. According to the random number table method, the patients were randomly divided into groups A, B, C and D. Group A 70 cases received massage once every 2 weeks. Group B 70 cases received massage once every 4 weeks. Group C 70 cases received massage once every 2 weeks and hot compress nursing before massage. Group D 70 cases received massage once every 4 weeks and hot compress nursing before massage. At 3 and 6 months of intervention, the recurrence rate of postoperative chalazion and meibomian gland function of children in the 4 groups were compared.Results:There were 65, 67, 66, 67 children completed the research in A, B, C and D group. The recurrence rates of postoperative chalazion in groups A, B, C, and D were respectively 10.77% (7/65) ,19.40% (13/67) ,1.52% (1/66) and 1.49% (1/67) after the intervention for 3 months, and the differences were statistically significant ( P<0.05). Further pairwise comparison showed that the recurrence rate in group C was lower than that in group A and B, and that in group D was lower than that in group A and B, and the differences were statistically significant ( P< 0.05). There were no statistically significant differences among the other groups ( P>0.05). After 6 months of intervention, the recurrence rates of postoperative chalazion in groups A, B, C, and D were respectively 9.23% (6/65) ,16.42% (11/67) ,1.52% (1/66) and 1.49% (1/67), and the differences were statistically significant ( P<0.05). Further pairwise comparison showed that the recurrence rate of group C was lower than that of group A and B, and that of group D was lower than that of group A and B, and the differences were statistically significant ( P<0.05). There was no significant difference between group A and B ( P>0.05). There were statistically significant differences in scores of the difficulty of meibum discharge of children in the 4 groups after 3 and 6 months of intervention ( P<0.05). Further pairwise comparisons showed that the score of difficulty of meibum discharge in group C was lower than that in group A and B, and that in group D was lower than that in group A and B, and the differences were statistically significant ( P< 0.05). There were no statistically significant differences among other groups ( P>0.05). After 3 and 6 months of intervention, there were statistically significant differences in the score of eyelid fat traits among the 4 groups ( P<0.05). Further pairwise comparison showed that the score of eyelid fat trait in group C was lower than that in group A and B, and that in group D was lower than that in group A and B, and the differences were statistically significant ( P<0.05). There were no statistically significant differences among other groups ( P>0.05) . Conclusions:Hot compress nursing can enhance the massage effect of the meibomian glands, improve function of the meibomian glands and facilitate the discharge of meibomian gland secretions, which can effectively reduce the recurrence rate of postoperative chalazion in children and is worthy of clinical promotion.
