Objective To investigate the relationships of the expression of microRNA-487a-3p (miR-487a-3p) and A kinase-interacting protein 1 (AKIP1) mRNA in the endometrial cancer (EC) tissue with the patient survival within 5 years after surgery. Methods The EC tissue and adjacent normal tissue samples were collected from 130 EC patients who underwent surgical treatment at the Fourth Hospital of Shijiazhuang from September 2016 to April 2019.qRT-PCR was employed to determine the expression levels of miR-487a-3p and AKIP1 mRNA.The patients were followed up for 5 years after surgery to record the survival status.After removal of the patients who missed follow-up,78 surviving patients were recorded as the EC survival group,and 34 deceased patients were recorded as the EC death group.The dual luciferase reporter gene assay was conducted to verify the targeting relationship between miR-487a-3p and AKIP1 mRNA.Comparison was conducted for the expression levels of miR-487a-3p and AKIP1 mRNA between adjacent normal tissue and EC tissue,the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue among patients with different clinical pathological parameters,and the clinical pathological parameters and the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue between the EC survival group and the EC death group.The correlations of miR-487a-3p and AKIP1 mRNA levels in the EC tissue with the degree of tumor differentiation,International Federation of Gynecology and Obstetrics (FIGO) stage,lymph node metastasis,and depth of muscle invasion were analyzed.The relationships of miR-487a-3p and AKIP1 mRNA with patient prognosis and the risk factors affecting the survival of EC patients within 5 years after surgery were analyzed to evaluate the value of miR-487a-3p and AKIP1 mRNA levels in predicting the survival of EC patients within 5 years after survival. Results The EC tissue showed lower miR-487a-3p level (0.41±0.08 vs. 1.00±0.05;t=71.306,P<0.001) and higher AKIP1 mRNA level (2.35±0.37 vs. 1.00±0.03;t=41.465,P<0.001) than the adjacent normal tissue.The miR-487a-3p low expression group and AKIP1 mRNA high expression group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer than the miR-487a-3p high expression group and AKIP1 mRNA low expression group,respectively (all P<0.05).The results of dual luciferase reporter gene assay showed that the relative activity of luciferase in the miR-487a-3p small interfering RNA (siRNA)+AKIP1 mRNA-wild type (WT) group was higher than that in the miR-487a-3p empty vector+AKIP1 mRNA-WT group (2.85±0.19 vs. 1.00±0.04;t=23.339,P<0.001).There was no significant difference in the relative activity of luciferase between the miR-487a-3p empty vector+AKIP1 mRNA-mutant type (MUT) group and the miR-487a-3p siRNA+AKIP1 mRNA-MUT group (1.04±0.05 vs. 1.05±0.03;t=0.420,P=0.683).MiR-487a-3p in the EC tissue had negative correlations with AKIP1 mRNA,FIGO stage,lymph node metastasis,and depth of muscle invasion and a positive correlation with the degree of tumor differentiation (all P<0.001).AKIP1 mRNA had positive correlations with FIGO stage,lymph node metastasis,and depth of muscle invasion and a negative correlation with the degree of tumor differentiation (all P<0.001).The 5-year overall survival rates in the miR-487a-3p high expression group and AKIP1 mRNA low expression group (89.47% and 84.91%) were higher than those in the miR-487a-3p low expression group and AKIP1 mRNA high expression group (49.09% and 55.93%),respectively (both P<0.05).The EC death group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer,higher AKIP1 mRNA level in the EC tissue,and lower miR-487a-3p level than the EC survival group (all P<0.05).Low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,deep invasion of muscle layer,low miR-487a-3p level,and high AKIP1 mRNA level were independent risk factors for the survival of EC patients within 5 years after surgery (all P<0.05).The area under curve (AUC) values of miR-487a-3p and AKIP1 mRNA alone (0.785 and 0.789,respectively) were lower than that of their combination (0.908) in predicting the survival of EC patients within 5 years after surgery (both P<0.05). Conclusion The EC tissue has a low miR-487a-3p level and a high AKIP1 mRNA level,both of which are correlated with clinicopathological parameters and prognosis and can be used to predict the survival of EC patients within 5 years after surgery.

Objective:To understand the current status of the level of chronic disease prevention and treatment literacy and health anxiety among chronic disease residents, as well as the urban-rural differences, in order to provide a basis for improving the level of chronic disease prevention and treatment literacy among chronic disease residents.Methods:This was a cross-sectional study. From July to August 2022, a multi-stage random sampling method was adopted to select 201 rural residents with chronic diseases in one rural health center and 242 urban residents with chronic diseases in two community health service centers. General demographic characteristics questionnaire, Chronic Disease Prevention and Control Literacy Questionnaire and Short version of Health Anxiety Scale were used for questionnaire survey.Results:There were 93 males and 108 females with chronic diseases in 201 rural chronic disease residents, and the age range was 19-69 years. There were 116 males and 126 females with chronic diseases in 242 urban chronic disease residents, and the age range was 18-69 years old. The score of chronic disease prevention and control literacy of rural chronic disease residents (7.86 ± 2.25) was lower than that of urban chronic disease residents (8.55 ± 2.03). The score of health anxiety of rural chronic disease residents (13.69 ± 5.26) was higher than that of urban chronic disease residents (11.67 ± 5.95). Both differences were statistically significant ( t=-3.43, 3.79, both P<0.05). After controlling the general demographic data, the layered linear regression analysis of rural chronic disease residents and urban chronic disease residents showed that health anxiety can negatively affect rural chronic disease residents and urban chronic disease residents of chronic disease prevention and treatment literacy level ( β=-0.185, -0.129, both P<0.05). Conclusions:There are urban-rural differences in chronic disease prevention and treatment literacy and health anxiety of chronic disease residents in community. It is necessary to strengthen psychological construction among rural chronic disease residents in order to improve their chronic disease prevention and treatment literacy.

Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.

OBJECTIVE: To investigate the potential antitumor effect and its mechanism of dihydroartemisinin (DHA) on diffuse large B-cell lymphoma (DLBCL). METHODS: OCI-Ly7 cells were respectively treated with different concentrations of DHA (0, 12.5, 25, 50 and 100 μmol/L) , CCK-8 was used to detect the cells viability. Subsequently, OCI-Ly7 cells were divided into 5 groups : DHA 0,25,50,100 μmol / L and DHA (100 μmol / L) + Colivelin (STAT3 activator). Aldehyde dehydrogenase (ALDH) positive cells were sorted by flow cytometry, the sphere-forming ability of stem cells was detected. Transwell assay and scratch test were used to analyze the invasion and migration of cells. Western blot was used to detect the expression of migration and invasion-related proteins, as well as the phosphorylation levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3(STAT3). RESULTS: DHA induced obvious cytotoxicity to OCI-Ly7 cells. Compared with the control group, the stem cell-like properties, invasion and migration of OCI-Ly7 were significantly inhibited in DHA 50 μmol/L group and 100 μmol/L group, while the phosphorylation levels of JAK2 and STAT3 were significantly reduced. There was no significant difference in DHA 25 μmol/L group compared with the control group. Treated with Colivelin, the inhibition of DHA on OCI-Ly7 stem cell-like properties, invasion and migration was significantly reversed, and the expression of p-STAT3 was significantly up-regulated. CONCLUSION DHA has antitumor effect on DLBCL, and its mechanism may be through inhibiting the activation of JAK2/STAT3 pathway to inhibit the stem cell-like properties, invasion and migration of DLBCL cells.

OBJECTIVE: To explore the role of chidamide in the regulatory mechanism of PD-1/PD-L1 immune escape signaling pathway in peripheral T-cell lymphoma. METHODS: Jurkat cell line was treated with different concentrations of chidamide. The changes of PD-L1 and JAK/STAT pathway gene mRNA expression and PD-L1 protein expression on cell surface were detected by fluorescence quantitative PCR and flow cytometry after treatment. RESULTS: Chidamide upregulated PD-L1 mRNA expression in Jurkat cell line in a dose-dependent manner (r=0.989). The mRNA expression of PD-L1 in 5.0 μmol/L group was 15.4 times higher than that in the control group. The proportion of PD-L1 positive cells in Jurkat cell line was less than 0.5%. Chidamide upregulated PD-L1 protein expression on Jurkat cell surface. Chidamide upregulated the mRNA expression of JAK2, STAT1 and STAT3 in Jurkat cell line. The level of up-regulation was obvious in high concentration group (5.0 μmol/L group). Meanwhile, the mRNA expression of SOCS1 and SOCS3, the negative regulatory genes upstream of the JAK/STA T pathway, were up-regulated. CONCLUSION In peripheral T-cell lymphoma, chidamide may up-regulate the expression of cell surface PD-L1 and induce T-cell chemokines by upregulation of STAT1 expression, thus improving the reaction rate of PD-1 monoclonal antibody and T-cell toxicity.

OBJECTIVE: To evaluate the incidence and clinical characteristics of metabolic syndrome (MS) within one year after hematopoietic stem cell transplantation (HSCT) in order to screen the risk factors for HSCT-MS, provide early intervention and improve the long-term quality of survival of patients. METHODS: The clinical follow-up data of 64 HSCT patients (survival time > 1 year) who received HSCT in our center from January 2007 to August 2018 were collected. Among them, 50 cases were allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 14 cases were autologous hematopoietic stem cell transplantation (auto-HSCT). The changes of MS-related indexes and clinical characteristics before and 1, 3, 6 and 12 months after HSCT were analyzed retrospectively. RESULTS: In allo-HSCT group, 14 cases were diagnosed as MS before operation, including high-density lipoprotein cholesterol (hypo-HDL-C)> hyper triglycerides（hyper-TG）> hyper fasting glucose（hyper-FBG）> abdominal obesity (AO) > hypertension. The preoperative diagnosis of MS in the auto-HSCT group was 5 cases, in the order of hyper-FBG> hyper-TG> AO> hypo-HDL-C> hypertension. Incidence of MS at 1, 3, 6 and 12 months after transplantation: 19, 26, 24 and 20 cases in the allo-HSCT group, respectively; auto-HSCT group were 7, 7, 6 and 6 cases, respectively. Hyper-TG and hypo-HDL-C were prominent in both groups. CONCLUSION The incidence of HSCT-MS is significantly higher within 1 year after HSCT. Regardless of allo-HSCT and auto-HSCT, the prevention and control of HSCT-MS is emphasized as an important guarantee to improve the long-term survival quality of HSCT patients.

OBJECTIVE: To analyze the significance of various abnormal signal patterns appreared in CML and B-ALL patients by using BCR/ABL/ASS1 tricolor dual-fusion probe, and to explore its application value in detecting BCR/ABL fusion gene and ASS1 gene deletion. METHODS: 50 newly diagnosed CML patients and 50 newly diagnosed B-ALL patients were detected by fluorescence in situ hybridization (FISH) with BCR/ABL/ASS1 tricolor dual-fusion probe. Meanwhile, karyotype analysis was performed on all the patients using the 24 hours short-term culture and R-banding. RESULTS: Among the 50 CML patients, Ph was found in 49 cases, 5 normal interphase karyotype was observed in 1 case. FISH detection showed that BCR/ABL fusion gene existed in all patients (100%), while the positive signal pathway showed that 1R1G2B2F was observed in 39 cases (78%), 2R1G2B1F in 2 cases (4%) and 1R1G2B1F in 6 cases (12%), simultaneous existence of 1R1G1B1F and 1R1G2B3F in 1 case (2%), 2R1G1B1F in 1 case (2%) 1R1G3B3F in 1 case (2%). FISH detection also showed that the karyotype of 6 case at ASS1 gene deletion (1R1G1B1F) all were simple t (9; 22) translocation, and other abnormalities not were observed. Among 50 cases of B-ALL, Ph was found in 13 cases, the numerical aberration and structural aberration of non t (9; 22) in 16 cases, normal karyotype in 20 cases, absence of mitotic phase in 1 case. FISH detection showed that 16 cases (32%) had BCR/ABL fusion gene including 13 cases (26%) of 1R1G2B2F, 1 case (2%) of stimultaneous exitance of 1R1G2B2F and 1R1G3B3F 1 case (2%) of 2R1G1B1F, 1 case (2%) of 1R1G3B2F. FISH detection also showed that 3 cases had BCR/ABL fusion gene, including 1 case with ASS1 gene deletion (2R1G1B1F), 1 case with classical t (9; 22) translocation (1R1G2B2F) and 1 case with BCR/ABL fusion gene and increase of ASS1 gene copy (1R1G3B3F). CONCLUSION Tricolor dual-fusion FISH probe for detecting BCR/ABL fusion gene and ASS1 gene deletion is simple, rapid, sensitive and stable. It can detect various forms of molecular fusion and avoid the false positive results due to coincidental overlap of signals generated by D-FISH probe and ES-FISH probe. In addition, this detection method not only can directly observe the presence or absence of ASS1 gene deletion, but also improve the reliability of the positive results of newly diagnosed BCR/ABL fusion gene and accuracy of monitoring results of minimal residual disease for the subsequent visit.

OBJECTIVE: To compare the clinical effects of ultrasonic subgingival debridement and ultrasonic subgingival debridement combined with manual root planing on severe periodontitis and then to investigate the necessity and significance of manual root planing. METHODS: Twenty-three patients with severe periodontitis participated in this split-mouth randomized-controlled clinical trial. Baseline examination and randomization were performed after supragingival scaling: each of the upper and lower jaws had a quadrant as the test group treated with ultrasonic subgingival debridement combined with manual root planing, whereas the other two quadrants were the control group treated with ultrasonic subgingival debridement. Treatment of each patient was at intervals of one week and completed in two visits. Clinical indicators concerning probing depth (PD), clinical attachment loss (CAL) and bleeding index (BI) were recorded at baseline and 1 month, 3 months, 6 months after treatment. RESULTS: There was no significant difference of periodontal indicators between the test group and the control group at baseline. Both the test group and control group resulted in significant improvement of PD, CAL and BI. One and three months after treatment, reduction of PD in the test group was higher than that in the control group [1 month: (2.13±1.31) mm vs. (1.79±1.33) mm, P<0.01; 3 months: (2.46±1.33) mm vs. (2.17±1.38) mm, P<0.01] and reduction of CAL in the test group was higher than that in the control group [1 month: (1.89±2.03) mm vs. (1.65±1.93) mm, P<0.01; 3 months: (2.03±2.05) mm vs. (1.83±1.97) mm, P<0.05]. Six months after treatment, PD in the test group and the control group decreased by (2.52±1.40) mm and (2.35±1.37) mm respectively, and the improvement in the test group was significantly better than that in the control group (P<0.01). CAL in the test group and the control group decreased by (1.89±2.14) mm and (1.77±2.00) mm respectively, and there was no statistical difference between the groups. There was no significant difference in the changes of BI between the two groups 1, 3 and 6 months after treatment. CONCLUSION Ultrasonic subgingival debridement combined with manual root planing has more reduction in PD and CAL compared with ultrasonic subgingival debridement. Therefore, it is still necessary to use manual instruments for root planing following ultrasonic subgingival debridement.
