Objective To investigate the expression of immunoglobulin γ-1 heavy chain constant region(IGHG1)in acute myeloid leukemia(AML)THP-1 cells and its influence on cell proliferation,apoptosis,and invasion via its regulation of the transforming growth factor β(TGF-β)/Smad pathway.Methods Bone marrow specimens from nine children with AML and eight children with fractures,human bone marrow stromal HS-5 cells,and human AML THP-1 and HL60 cells were used in the research.Western blot was used to detect IGHG1 protein expression.THP-1 cells were divided into a blank group(without any treatment),si-NC group,si-IGHG1-1 group,si-IGHG1-2 group,si-IGHG1-3 group,TGF-β group,si-IGHG1-1+TGF-β group,and si-IGHG1-1+TGF-β +LY364947 group.Cell proliferation was measured by CCK-8 method.Flow cytometry and Transwell experiment were performed to measure apoptosis and invasion.Western blot was used to detect the protein expression of IGHG1,TGF-β,p-Smad2 and p-Smad3 in each group of cells.Results Compared with the bone marrow of children with fractures,the bone marrow of children with AML(P<0.05)had significantly higher expression levels of IGHG1((0.24±0.03)vs(0.87±0.12)).Compared with HS-5 cells,human AML THP-1 and HL60 cells had significantly increased expression levels of IGHG1((0.89±0.14)(0.75±0.08)vs(0.21±0.02))(P<0.05).Compared with the blank group,the si-IGHG1-1 group of THP-1 cells showed significantly reduced OD450 values(24 h,48 h,72 h),invading cell numbers and protein expression of TGF-β,p-Smad2,p-Smad3 and their apoptosis rate was increased(P<0.05),while the corresponding indexes showed the opposite trend in the TGF-β group(P<0.05).TGF-β reversed the effects of silencing IGHG1 on the proliferation,apoptosis and invasion of THP-1 cells.Compared with the si-IGHG1-1+TGF-β group,the si-IGHG1-1+TGF-β+LY364947 group had significantly decreased TGF-β,p-Smad2,p-Smad3 and protein levels,OD450 values and cell invasion numbers and the apoptosis rate was increased(P<0.05).Conclusions IGHG1 is highly expressed in AML cells.Silencing the IGHG1 gene can inhibit the proliferation and invasion of AML cells and promote the apoptosis of AML cells.This mechanism may be related to the inhibition of the TGF-β/Smad pathway.
RESUMEN
Objective:To analyze the costs and effectiveness of five common screening modes and genetic screening for thalassemia in China in order to find the optimal way and provide evidence for the implementation of thalassemia prevention and control projects in Hunan Province.Methods:From June 2020 to April 2021, 12 971 couples from 14 cities and autonomous prefectures in Hunan Province were selected as the study population. The diagnosis of thalassemia was based on the results of genetic testing. Results of routine blood test and hemoglobin electrophoresis were collected and analyzed. The efficacy of five screening modes, at the cut-off value of <80 fl or 82 fl for the mean corpuscular volume (MCV), was analyzed by positive predictive value, negative predictive value, Jorden index and cost-effectiveness ratio. Sensitivity analysis was used to assess the feasibility of genetic screening at different costs after fixing the costs of routine blood and hemoglobin electrophoresis. The five thalassemia screening models are as follows: Mode 1: The woman had a blood routine test first. If the result was positive, the spouse required a blood routine test. If both results were positive, a thalassemia gene test should be offered to the couple. Mode 2: Both husband and wife were screened by blood routine and hemoglobin electrophoresis. If one or both of them were positive, both would be tested for thalassemia gene. Mode 3: The couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing. Mode 4: The woman was screened by blood routine and hemoglobin electrophoresis. If any one of them was positive, the woman would be tested for thalassemia gene. If the gene test result was positive, the spouse should receive thalassemia gene. Mode 5: Both spouses conducted a blood routine test. If either was positive, both would conduct hemoglobin electrophoresis test. If both were positive, both spouses should receive thalassemia gene testing. Gene testing mode: The woman would be tested for thalassemia, and her spouse would have thalassemia test too if her result was positive.Results:When using MCV<80 fl as the cut-off for diagnosing thalassemia, the Youden indices of the five prenatal screening modes in Hunan Province were 0.551, 0.639, 0.898, 0.555 and 0.356, while when using MCV<82 fl as the cut-off, the Youden indices were 0.549, 0.629, 0.851, 0.548 and 0.356. When the MCV cut-off value was <80 fl, the missed diagnosis rates of the five screening modes were 44.44%, 0.00, 0.00, 18.52% and 62.96%, and the cost-effectiveness ratios were 21 709, 250 939, 76 870, 138 463 and 92 860 yuan (RMB)/couple, respectively. When the price of genetic testing was lower than 55 yuan (RMB), the cost-effectiveness ratio of genetic screening was lower than that of Mode 3.Conclusions:MCV<80 fl can be considered as the positive criteria in blood routine screening for thalassemia in Hunan Province, and the cost-effectiveness ratio of Mode 3 (the couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing) is the best. Genetic screening has certain advantages with the decreasing price.
RESUMEN
We used network pharmacology to predict the mechanism in the treatment of rheumatoid arthritis (RA) via modified Gan Cao Fu Zi Decoction (GCFZ), and validated the results of the analysis and explored the pharmacodynamic effects of GCFZ through animal experiments. Firstly, TCMID, SymMap, HERB, STITCH and GEO databases were utilized to obtain the target genes of GCFZ for the treatment of RA, which yielded a total of 1 250 differentially expressed genes for RA, 534 genes for GCFZ targets and 83 intersecting genes. Then functional enrichment analysis of the intersecting genes was performed through GO and KEGG databases, and the results revealed that GCFZ and its active ingredients mainly functioned through cytokine pathways, where chemokine signaling pathway and tumor necrosis factor (TNF) signaling pathway were enriched with a high number of genes. Cytoscape 3.8.0 software was used to construct the drug-target-disease network and screen key proteins, which included TNF, C-X-C chemokine ligand 8 (CXCL8), C-X-C chemokine ligand 10 (CXCL10), C-C chemokine ligand 5 (CCL5), C-X-C chemokine ligand 2 (CXCL2) and C-X-C chemokine receptor type 4 (CXCR4). The molecular docking technology was used to confirm the binding ability of the main active ingredients of GCFZ to the core proteins. Additionally, the therapeutic effects of GCFZ in low (4 g·kg-1), medium (8 g·kg-1) and high (16 g·kg-1) dose groups were investigated by constructing the collagen-induced arthritis (CIA) rat model. X-ray imaging approach, HE staining and Safranin O-Fast Green staining showed that GCFZ treatment significantly improved bone destruction, synovial hyperplasia and cartilage damage in CIA rats, while immunofluorescence results showed that GCFZ treatment could regulate the expression of TNF, CXCL8 and CCL5. In summary, our results indicate that GCFZ contains a variety of small molecule pharmacodynamic substances, which can exert therapeutic effects via multiple targets and pathways, and obviously reduce the symptoms of arthritis in CIA rats. This animal experiment of our research was approved by the Experimental Animal Management and Ethics Committee of Bengbu Medical College.
RESUMEN
OBJECTIVE@#To investigate the effect of miR-22 targeting formin-like protein 2 (FMNL2) on the migration and apoptosis of childhood acute myeloid leukemia (AML) cells.@*METHOD@#Peripheral blood samples from 11 children with AML, 10 children with immune thrombocytopenia, human AML cell lines TF-1a, HL-60, THP-1 and human bone marrow stromal cells HS-5 were used as the research objects. UniCel DxH 800 automatic hematology analyzer detected platelet count, hemoglobin, and white blood cell count in peripheral blood samples, and RT-qPCR detected miR-22 expression in peripheral blood samples and AML cells. HL-60 cells were transfected with LipofectamineTM 2000 kit, the experiments were divided into seven groups: blank (no cells transfected), miR-NC, miR-22 mimics, si-NC, si-FMNL2 , miR-22 mimics+OE-NC and miR-22 mimics+OE-FMNL2 . RT-qPCR was used to detect the expression of miR-22 in each group. Transwell was used to detect cell migration. Flow cytometry was used to detect cell apoptosis. Dual-luciferase reporter gene detection experiments verified the targeting relationship between miR-22 and FMNL2 . Western blot was used to detect the expression of FMNL2 protein.@*RESULTS@#Compared with the control group, the number of leukocytes in the peripheral blood of children with AML was significantly increased (P <0.001), while the concentration of hemoglobin and the number of platelets were significantly decreased P <0.001). The expression level of miR-22 in peripheral blood of children with AML was significantly lower than that in control group (P <0.001). Compared with HS-5 cells, the expression levels of miR-22 in TF-1a, HL-60, and THP-1 cells were significantly decreased (P <0.05), and in HL-60 cells was the lowest. Therefore, HL-60 cells were selected for subsequent experiments. Up-regulation of miR-22 or silencing of FMNL2 could reduce the number of migrating cells and increase apoptosis rate (P <0.05). MiR-22 targeted and negatively regulated the expression of FMNL2 . FMNL2 overexpression reversed the effects of up-regulated miR-22 on migration and apoptosis of HL-60 cells.@*CONCLUSION@#MiR-22 can inhibit the migration and promote apoptosis of HL-60 cells by down regulating the expression of FMNL2 .

OBJECTIVE@#To compare the clinical efficacy and its effect on serum levels of tumor necrosis factor α(TNF-α), interleukin 1β(IL-1β), interleukin 6 (IL-6) and prostaglandin E2 (PGE2) between short needling (close-to-bone needling) and conventional acupuncture for knee osteoarthritis (KOA) with blood stasis obstruction.@*METHODS@#A total of 68 KOA patients with blood stasis obstruction were randomized into a short needling group (34 cases, 3 cases dropped off) and a conventional acupuncture group (34 cases, 3 cases dropped off). The same acupoints (Dubi [ST 35], Neixiyan [EX-LE 4], Binzhong [Extra], Liangqiu [ST 34], etc. on the affected side) were selected in the two groups. In the short needling group, short needling technique was adopted, the needles were slowly inserted and the needle bodies were shaken, thus gradually penetrated to the bone. In the conventional acupuncture group, conventional acupuncture was adopted, the needles were penetrated to the muscle. After qi-arrival, Dubi (ST 35) and Neixiyan (EX-LE 4), Zusanli (ST 36) and Liangqiu (ST 34) were connected with CMNS6-1 electronic acupuncture instrument, with disperse-dense wave, 2 Hz/10 Hz in frequency, the current intensity was based on patients' feeling, the needles were retained for 30 min, at the same time, the knee joint was irradiated for 30 min with a special electromagnetic wave apparatus in the two groups. Once every other day, 3 times a week for 4 weeks. Before and after treatment, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, knee joint pain visual analogue scale (VAS) score, inflammatory response related indexes (serum TNF-a, IL-1β, IL-6 and PGE2) and knee joint ultrasound were observed,and the clinical effect was evaluated in the two groups.@*RESULTS@#After treatment,the pain, stiffness, function scores and total scores of WOMAC were decreased as compared with those before treatment in the two groups (P<0.05), except for the pain score, the changes of above scores in the short needling group were greater than the conventional acupuncture group (P<0.05). After treatment, the VAS scores, serum levels of TNF-a, IL-1β, IL-6, PGE2 and knee joint synovium thickness, intra-articular effusion were decreased as compared with those before treatment in the two groups (P<0.05), the levels of TNF-a, IL-1β, IL-6 in the short needling group were lower than the conventional acupuncture group (P<0.05). The total effective rate in the short needling group was 87.1% (27/31), which was superior to 83.9% (26/31) in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Short needling could improve the knee joint function, relieve the pain and inflammatory response, improve the knee joint synovium inflammatory response, reduce the knee joint intra-articular effusion for KOA patients, its effect is better than conventional acupuncture.

RESUMEN
@#Objective To analyze the results and diagnostic value of postoperative chylous test of pleural effusion and to verify the clinicopathological factors affecting the results of chylous test. Methods The clinical data of 265 consecutive patients undergoing selective surgery at the Department of Thoracic Surgery, Shangjin Nanfu Hospital between May and August 2020 were retrospectively analyzed, including 106 males and 159 females with an average age of 53.0±12.2 years. According to the results of the chylous test on the operation day and postoperative first and second days, the patients were divided into two subgroups, including a positive group and a negative group, and the clinical data of the two groups were compared. Sensitivity and specificity of the chylous test were calculated. The influencing factors for chylous test were analyzed by multiple logistic regression analysis. Results The positive rate of chylous test was 91.7%, 95.8% and 87.9% on the operation day and postoperative first and second days, respectively. There was no statistical difference in age, sex, surgical type, surgical approach, surgical site, surgical time, degree of lymph node dissection, treatment of thoracic duct, 24 hours pleural fluid drainage or 24 hours protein and fat food intake between the positive group and the negative group (P>0.05). The diagnostic sensitivity and specificity of the chylous experiment were 100.0%and 4.0%, respectively. Multiple logistic regression analysis showed that the surgical site (left/right chest) might be an influencing factor for the results of the chylous test (P=0.043, OR=0.458, 95%CI 0.216-0.974). Conclusion The positive rate of chylous test of pleural effusion after thoracic surgery is very high. The chylous test produces a high misdiagnosis rate of chylothorax. The surgical site (left/right chest) may be an influencing factor for chylous test. The positive result of chylous test is not recommended as the direct diagnostic basis for postoperative chylothorax and guidance of the subsequent treatment.

RESUMEN
【Objective】 To analyze the influencing factors of blood re-donation among street voluntary blood donors in Nanjing, and to provide basis for increasing the proportion of blood donation/donors. 【Methods】 29 650 street voluntary blood donors in Nanjing from May 21, 2017 to May 21, 2018 in the information management system of Nanjing Red Cross Blood Center were taken as the sampling population, and 2 965 (10%) were randomly selected to ask whether they donated again and reasons by telephone calls. They were divided into re-donation group and lapsed group.The demographic variables and donation frequency of street blood donors in the two groups were analyzed and compared by Chi-square test, and multivariate logistic regression was used to analyze the influencing factors of re-donation of blood donors. 【Results】 The response rate of this survey was 63.37% (1 879/2 965), and the re-donation rate of street blood donors in Nanjing from May 2017 to May 2018 was 40.34% (758/1 879), which was lower than the re-donation rate of global blood donors as 50%. The primary motivation for street blood donors in Nanjing to donate blood again was "help others", accounted for 62.27% (472/758), and the primary deterrent to redonate blood again was "too busy to donate blood", accounted for 49.15% (551/1 121). 【Conclusion】 There is a certain gap between the rate of blood re-donation in Nanjing and worldwide, therefore, further incentive measures are needed and flexible recruitment and blood donation methods should be adopted to facilitate blood donation for donors.
RESUMEN
【Objective】 To explore the promote and deter factors of blood donation among street blood donors in Nanjing, in order to improve the accuracy of street blood donors recruitment. 【Methods】 A questionnaire with high confidence was designed based on the theory of planned behavior(TPB). The multi-stage hierarchical sampling method was adopted according to the geographical location and economic development level of 11 districts(regions) in Nanjing, and the street blood donors were divided into three groups according to the history of blood donation: one donation(n=361), donation numbers ≥ 2(n=417)and non-donation (n=241). The blood donation behavior was investigated from four aspects as external promote factors (such as seeking a free blood examination, self-interest factors, etc.), internal promote factors(such as altruistic, self-interest factors, blood donation can help others, etc.), external deter factors (too busy to donate blood, opposition from my family, etc.) and internal deter actors ( worry about dizziness after blood donation, fear of needles, ect.). The database was established using Epidata software, and chi-square test was applied for statistical analysis between groups. 【Results】 The groups mainly affected by the promote factors (altruistic and self-interest factors) of Nanjing street population in blood donation were unmarried, 18~24 years old, childless, below bachelor degree, and have barely no income. The main groups less affected by the deter factors were students, male, unmarried, 18~24 years old, childless and have barely no income.Promote factors increases with the number of blood donations, while deter factors decreases with the number of blood donation. 【Conclusion】 TBP can better analyze and explain the promote and deter factors affecting blood donation behavior among street blood donors in Nanjing, which is helpful for blood stations to formulate targeted measures to improve the availability of street blood donors.

【Objective】 To investigate the feelings of blood donors during blood donation and its influencing factors, thus providing references for high quality blood donation service for blood banks. 【Methods】 A self-developed questionnaire concerning voluntary blood donation was randomly issued by the research group and recruited investigators among blood donors in 6 street blood donation sites of Nanjing Red Cross Blood Center at weekends during December 1~23, 2018. The basic information of blood donors, the difference of feelings during blood donation and the influencing factors were analyzed by descriptive analysis, chi-square test and binary Logistic regression analysis, respectively. 【Results】 A total of 405 questionnaires were issued, and all 405 copies were valid, with the response rate at 100% (405/405). Among the valid questionnaires, 46.67% (189/405) were first-time blood donors, 27.65% (112/405) had donated for 2~3 times, and 25.68% (104/405) donated more than 4 times. 53.59%(97/181), 23.7%(43/181) and 22.65%(41/181) of the above three groups of blood donors worried about the needles, and 55.48%(81/146), 22.60%(33/146) and 21.92%(32/146) worried about the blood outflow, 52.69% (88/167), 28.14% (47/167), and 19.16% (32/167 )worried about the pain during blood collection (P0.05). There were differences in blood donation experience among the three groups (P<0.05), and gender (P<0.05) was its influencing factor showed by binary Logistic regression analysis. 【Conclusion】 The majority of blood donors, who have donated at the street sites of Nanjing, are worried during blood donation collection. Therefore, the blood centers should provide high-quality services and humanized nursing interventions as well as strengthen the citizens′ awareness of blood donation.
RESUMEN
Background: Developing the natural medicine that allow for the specific targeting cytotoxicity is a very important research area in the development of anti-tumor drugs. Aims and Objectives: This study was conducted to determine the targeted inhibitory effects of luteolin-loaded Her-2-poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) on gastric cancer cells and to delineate the mechanism underlying the inhibition of tumors by luteolin. Materials and Methods: Luteolin-loaded Her-2-PLGA NPs (Her-2-NPs) were prepared, physically and chemically characterized, and their effects on gastric cancer cells were investigated. The rate of NP uptake by cells and the cell morphology were observed using confocal microscopy; the rates of cell proliferation and apoptosis were identified using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide assay and flow cytometry, respectively; and the mRNA and protein expression levels of forkhead box protein O1 (FOXO1) were determined using quantitative polymerase chain reaction and Western blotting, respectively. Results: Compared with nontargeted microspheres, Her-2-NPs led to significantly enhanced uptake of luteolin by SGC-7901 cells. Luteolin-loaded Her-2-NPs also significantly inhibited the proliferation of gastric cancer cells, weakened their migratory ability, and increased both the mRNA and protein expression levels of FOXO1. Conclusion: Luteolin-loading of Her-2-NPs could potentially be used as a novel anti-cancer drugs for targeted cancer therapy.

@#【Objective】To explore the effects of liver dysfunction in the third trimester of pregnancy on maternal outcomes and identify the factors affecting the maternal prognosis.【Methods】We collected the clinical data of 1 113 women with liver dysfunction in the third trimester of pregnancy (case group) and 1 113 normal pregnancies (control group) from the Third Affiliated Hospital of Sun Yat-sen University between January 2015 and December 2018. We compared the rates of cesarean section,premature delivery,placental abruption,postpartum hemorrhage and maternal mortality in the two groups,conducted the univariate and multivariate analysis for the case group and determined the prognostic risk factors by using Logistic regression. Receiver operating characteristic(ROC)curve analysis was applied to estimate the value of each independent risk factor for predicting liver dysfunction-related maternal mortality. 【Results】The rates of cesarean section,premature delivery,placental abruption,postpartum hemorrhage in the case group were higher than those in the control group(P < 0.05),and the odds ratios(ORs)were 3.59 ,7.81 ,10.68 and 2.93 ,respectively. The maternal mortality in the case group(1.2%)was higher than that in the control group(0.0%)(P < 0.05). Logistic analysis revealed that high total bilirubin(TBIL),low prothrombin activity(PTA)and low fasting plasma glucose(FPG)were independent risk factors for liver dysfunction- related maternal mortality. The ROC curve analysis indicated that when TBIL was 235.4 μmol/L,the Youden′ s index in maximum was 0.331 with sensitivity of 0.818 and specificity of 0.513. When PTA was 20.5% ,the Youden′ s index in maximum was 0.366 with sensitivity of 0.821 and specificity of 0.545. When FPG was 3.11 mmol/L,the Youden′s index in maximum was 0.405 with sensitivity of 0.769 and specificity of 0.636.【Conclusion】Liver dysfunction in the third trimester of pregnancy has adverse effects on maternal outcomes. TBIL ,PTA and FPG are the factors affecting the maternal prognosis and may have certain predictive value for maternal death.

Objective@#To analyze the situation of AIDS knowledge and discrimination among freshmen in Chengdu city, and to explore possible effects of AIDS knowledge on discrimination.@*Methods@#A cluster random sampling was employed to investigate 1 053 college students from 11 universities in Chengdu about their HIV/AIDS knowledge and discrimination. The scores of AIDS knowledge and discrimination of students with different characteristics were analyzed, and the influence path of AIDS knowledge on AIDS discrimination were further analyzed based on different peer relationships.@*Results@#The total scores of AIDS knowledge was negatively correlated to AIDS discrimination( r s =-0.13, P <0.01). After adjusting for confounding factors, the total score of AIDS knowledge was associated with the total score of AIDS discrimination( β =-0.12, P <0.01). AIDS knowledge played a role in AIDS discrimination in intimate, general and unfamiliar peer relationships, with standardized path coefficients of -0.20, -0.24 and -0.18 respectively( P <0.01).@*Conclusion@#AIDS knowledge are correlated with discrimination among freshmen under different peer relationships. More anti-AIDS discrimination courses should be added to AIDS education to reduce the students’ fear and stigma of HIV/AIDS patients and related risk groups.
RESUMEN
Objective:To investigate the relationship between peritoneal thickness and baseline solute transport function in peritoneal dialysis (PD) patients, and analyze the factors affecting the function of peritoneal transport.Methods:Non-diabetic end-stage renal disease (ESRD) patients admitted to the Second Hospital of Longyan City from January 2017 to June 2019 were enrolled in this study. The thickness of the peritoneal membrane was measured by color ultrasound instrument before the peritoneal catheterization. Standard peritoneal equilibration test (PET) was performed after one month of peritoneal dialysis. The ratio of corrected creatine in 4 h dialysate to 2 h serum creatine (D/Pcr) was used as a solute baseline transport index, and according to the D/Pcr evaluation results, the patients were divided into high/high average transfer (H) group (D/Pcr≥0.65) and low/low average transfer (L) group (D/Pcr<0.65). The clinical data, peritoneal thickness and peritoneal dialysis related indicators between the two groups of patients were compared. Binary logistic regression was used to analyze the factors affecting the function of peritoneal transport.Results:The amount of peritoneal ultrafiltration in H group was significantly lower than that in L group, intraperitoneal creatinine clearance (Ccr) and peritoneal thickness were significantly higher than those in L group (both P<0.05). Pearson and Spearman correlation results showed that the thickness of peritoneal membrane positively correlated with D/Pcr ( r=0.673, P<0.05), peritoneal Ccr ( r=0.261, P<0.05), and negatively correlated with ultrafiltration of peritoneal dialysis ( r=-0.365, P<0.05). Partial correlation analysis showed that the peritoneal thickness was positively correlated with the solute transport index D/Pcr ( r=0.539, P<0.05) and the peritoneal Ccr ( r=0.338, P<0.05). Binary logistic regression results showed that peritoneal thickening was a risk factor affecting peritoneal transport function ( OR=1.175, 95% CI 1.009-1.369, P<0.05). Conclusions:There is a positive correlation between the peritoneal membrane thickness and the baseline solute transport index in patients with non-diabetic peritoneal dialysis. Peritoneal thickening is a risk factor affecting peritoneal transport function.
