ABSTRACT
Trials within cohorts （TwiCs） are design methods derived from randomized controlled trials （RCTS）. They have been widely used in chronic disease areas such as tumors and cardiovascular diseases. The basis of the TwiCs design is a prospective cohort of specific diseases. When RCTS need to be implemented， some patients meeting the inclusion and exclusion criteria are randomly sampled from the cohort to receive "trial interventions"， while the remaining patients in the cohort who meet the inclusion and exclusion criteria continue to receive conventional treatment as control groups. By comparing the efficacy differences between the intervention measures of the trial group and the control group， the efficacy of intervention measures was evaluated. Within the cohort， the same process could be repeated to carry out multiple RCTS， so as to evaluate different intervention measures or compare the efficacy of different doses or timing of interventions. Compared with classical RCTS， TwiCs make it easier to recruit patients from the cohort and have higher external validity， providing a new research paradigm for improving the efficiency and applicability of RCTS in clinical practice. However， TwiCs may also face the challenge of poor compliance of patients in the cohort. Researchers need to take effective measures to control these patients in the design and operation of TwiCs. This article focused on the methodological key points during the implementation of TwiCs， including multi-stage informed consent （patients are informed of consent at three stages： entering the cohort， entering the trial group， and after the trial）， randomization procedures （only random sampling of patients from the cohort to receive "trial interventions"）， sample size calculation， and statistical analysis methods. The article also compared the differences between TwiCs and traditional RCTS and illustrated TwiCs research design and analysis with examples， so as to provide new research ideas and methods for clinical researchers.
ABSTRACT
The quality evaluation of the blind method is to evaluate the clinical blind data obtained from clinical trials adopting the blind method and judge the effectiveness of the blind method by investigating the blind effect of different blind objects. A successful blind method can avoid the influence of subjective factors on the test results of subjects and researchers to a certain extent. The quality evaluation of the blind method can reflect not only the effectiveness of the blind method but also the accuracy and credibility of clinical trial results. In recent years， randomized controlled trials have been widely used in the evaluation of the clinical efficacy of traditional Chinese medicine （TCM）， but the quality of the implementation of blind methods is uneven， and the evaluation criteria have not yet been formed. In this paper， the data collection methods， calculation principles， advantages， and disadvantages of two quantitative quality evaluation methods of blind methods， namely James Blinding Index （JBI） and Bang Blinding Index （BBI）， were introduced. The two indexes were analyzed in a randomized controlled trial of acupuncture and moxibustion to relieve postoperative oral pain. The calculation process of the results was demonstrated by R software and visualized by forest map. At the same time， a tool table was designed to facilitate the collection of evaluation data of blind methods in TCM clinical trials at different stages. Finally， the necessity and feasibility of quality evaluation of blind method in TCM research were discussed to provide a basis for evaluating and improving the quality of blind method implementation in TCM clinical trials.
ABSTRACT
Objective:To investigate the value of hemorrhage after thrombolytic (HAT) score and neutrophil to lymphocyte ratio (NLR) in combination predicting symptomatic intracerebral hemorrhage (sICH) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Consective patients with AIS received intravenous thrombolysis with ateplase in Tianjin TEDA Hospital from January 2016 to December 2021 were retrospectively enrolled. sICH was defined as cerebral CT showing hemorrhage at any part of the brain after intravenous thrombolysis, and the National Institutes of Health Stroke Scale (NIHSS) score was increased by≥4 compared with the baseline, or there was a manifestation indicating clinical aggravation. Univariate analysis was used to compare the baseline data of sICH group and non-sICH group. A binary multivariate logistic regression model was used to determine the independent influencing factors of sICH. The receiver operating characteristic (ROC) curve was used to evaluate the value of HAT score and NLR in combination predicting sICH. Results:A total of 429 patients with AIS were enrolled. Univariate analysis showed that there were significant differences in atrial fibrillation, systolic blood pressure, NLR, HAT score and NIHSS score between the sICH group and the non-sICH group (all P<0.05). Multivariate analysis showed that NLR (odds ratio [ OR] 1.405, 95% confidence interval [ CI] 1.193-2.958), HAT score ( OR 1.512, 95% CI 1.207-3.169) and NIHSS score ( OR 1.221, 95% CI 1.082-2.634) had significant independent correlation with sICH after adjusting for atrial fibrillation and systolic blood pressure. The ROC curve showed that the areas under the curve of HAT score, NLR and their combination predicting sICH were 0.719 (95% CI 0.609-0.832), 0.723 (95% CI 0.618-0.835) and 0.854 (95% CI 0.765-0.931), respectively. The areas under the curve of the two methods in combination were significantly larger than those of the single method ( P=0.029 and 0.032, respectively), and their sensitivity and specificity were 74.1% and 83.5% respectively. Conclusion:Combined HAT score and NLR is of high value in predicting sICH after intravenous thrombolysis in patients with AIS, and has clinical application potential.
ABSTRACT
Pulmonary hypertension(PH)is commonly seen in preterm infants with bronchopulmonary dysplasia(BPD)and is significantly associated with increased mortality.The pathophysiological basis of PH is pulmonary vascular dysplasia or remodeling, and airways hyperresponsiveness.At present, management of BPD-PH should be comprehensive supportive therapy and focus on targeted pharmacotherapies, including various pulmonary vasodilators with different vasoactive mechanisms, such as phosphodiesterase inhibitors, endothelin receptor antagonists and prostaglandins analogs.However, although expert consensus recommends targeted pulmonary arterial hypertension therapy, high-quality clinical studies on the safety and efficacy of these drugs are few.Pulmonary vascular remodeling inhibitors and stem cell therapy have enormous potential to reduce pulmonary hypertension and further research and more data are needed.
ABSTRACT
Target trial emulation， using observational data to emulate a target trial， applies the study design principles of randomized controlled trials to observational studies that aim to estimate the effect of an intervention. The advantage of target trial emulation is that observational data is used to emulate a target trial when it is not appropriate to conduct randomized controlled trials. Target trial emulation can control bias caused by the design of observational studies， and improve the effectiveness of causal inference from observational data. This paper introduced the methodological framework and key points in terms of eligibility criteria， treatment strategies， assignment procedures， grace period， outcomes， follow-up period， effect contrasts， and statistical plan for implementing target trial emulation. This article elucidated the feasibility and necessity of applying target trail emulation in the realm of traditional Chinese medicine researches， and highlighted the challenges encountered in its implementation， such as the need for specialized personnel， data collection and integration， and the control of confounding factors.
ABSTRACT
OBJECTIVE To analyze the research status， hotspots， and trend of the clinical comprehensive evaluation of Chinese patent medicine in China. METHODS Based on CNKI， VIP and Wanfang database， clinical comprehensive evaluation of Chinese patent medicine was used as the subject of retrieval， and the retrieval time was from the inception to October 30th， 2022. CiteSpace 6.1.R3 and VOSviewer were used to conduct a visualization analysis of the relative literature of clinical comprehensive evaluation of Chinese patent medicine in terms of annual publication quantity， authors， institutions， keywords， etc. RESULTS & CONCLUSIONS A total of 1 460 pieces of literature related to the clinical comprehensive evaluation of Chinese patent medicine were included. The overall annual publication quantity showed a growth trend. There were 714 authors in the included literature. The institutions with a large publication quantity included the Chinese Academy of Traditional Chinese Medicine， Beijing University of Chinese Medicine， Tianjin University of Traditional Chinese Medicine， etc.， and there was little cooperation among the authors and institutions. High-frequency keywords included Chinese patent medicine， safety， adverse drug reactions， rational drug use， etc. Research hotspots focused on the safety and effectiveness evaluation of Chinese patent medicine. It may be a research trend in this field to strengthen the prescription review of Chinese patent medicine， and build a multi-dimensional and multi-criteriaclinical comprehensive evaluation system for the rational use of Chinese patent medicine.
ABSTRACT
Syndrome differentiation and treatment is a unique mode of diagnosis in traditional Chinese medicine （TCM）. The establishment of scientific and standardized syndrome diagnosis standards is an important link to evaluate the clinical efficacy of TCM objectively and systematically， and also a prerequisite for the promotion and development of TCM to obtain international recognition. This article reviewed the basic modes and existed problems of the current syndrome diagnosis criteria， and proposed to construct a multidimensional core information set integrating the minimized core symptoms， the artificial intelligence signs， the multi-modal laboratory indicators， and multi-omics specific markers， so as to present syndrome characteristics from multiple perspectives systematically. This paper also described the basic mode， constructure， as well as the process and methodology to be adopted in the establishment of the standardized diagnostic research method. The core information set of diagnostic symptoms not only took into account the specificity of the disease， but also improved the inconsistency due to the complexity and subjectivity of the syndrome differentiation， thereby providing a methodological basis for the standardization of TCM syndrome differentiation in clinical research.
ABSTRACT
Colorectal cancer is one of the most common malignant tumors of digestive tract. In 2020， 1.93 million new cases of colorectal cancer were diagnosed globally， ranking third in the global incidence spectrum， and 930 000 new deaths were reported， ranking second in the global cause of death spectrum. Meanwhile， the medical cost of metastatic colorectal cancer is the highest among all stages. A large number of studies have demonstrated that traditional Chinese medicine（TCM） treatment can bring clinical benefits to patients with metastatic colorectal cancer with unique efficacy. In order to further standardize the TCM diagnosis and treatment for metastatic colorectal cancer and improve the level of TCM diagnosis and treatment， Xiyuan Hospital， China Academy of Chinese Medical Sciences， together with other relevant units in China， according to the guideline development process of the World Health Organization Handbook for Guideline Development and the relevant requirements of the Clinical Evidence Grading Criteria on TCM Based on Evidence Body， the Regulations for Group Standards of China Association of Chinese Medicine and others， combined with the characteristics of TCM diagnosis and treatment and the actual situation in China， the Guidelines for TCM Diagnosis and Treatment of Metastatic Colorectal Cancer was developed in accordance with the Catalogue of TCM Diagnosis and Treatment Plans for 105 Diseases in 24 Specialties issued by Department of Medical Administration of National Administration of TCM.
ABSTRACT
Colorectal cancer is one of the common malignant tumors with high morbidity， and changes in lifestyle， dietary structure and environment in China in recent decades have been associated with an increase in the incidence of colorectal cancer. A large number of studies have shown that traditional Chinese medicine（TCM） can be used as a complementary and alternative treatment for colorectal cancer after conventional western medicine treatment. TCM physicians have accumulated a lot of clinical experience in the treatment of patients with stage Ⅰ-Ⅲ colorectal cancer， and have proved that TCM has unique efficacy， but there is still a lack of relevant clinical practice guidelines to standardize and guide the diagnosis and treatment of TCM. Based on this， according to the guideline development process of the World Health Organization Handbook for Guideline Development and the Clinical Evidence Grading Criteria on TCM Based on Evidence Body， under the framework of relevant laws， regulations and technical guidance documents， combined with the evidence of relevant domestic and foreign clinical research in recent years for evidence grading and opinion recommendation， and then the Guidelines for TCM Intervention After Conventional Western Medicine Treatment for Stage Ⅰ-Ⅲ Colorectal Cancer were developed by expert consensus. This guideline introduces the etiology， pathogenesis， syndrome differentiation and treatment of TCM intervention for colorectal cancer， which can provide guiding opinions for TCM clinicians and clinicians of integrated traditional Chinese and western medicine engaged in the prevention and treatment of colorectal cancer.
ABSTRACT
Objective To analyze the epidemiological characteristics and drug resistance of pathogenic bacteria in 276 hospitalized children with lower respiratory tract infection to facilitate prevention and treatment. Methods Among of 276 hospitalized children with lower respiratory tract infection from January 2019 to December 2021 were analyzed. Data on the distribution of pathogenic bacteria were collected and analyzed. At the same time, the information on drug resistance was collected, and the potential relationship between pathogen distribution and drug resistance was briefly analyzed and discussed. Results A total of 532 strains of pathogenic bacteria were detected in the blood samples from 276 patients in this study. There were 207 strains of Gram-positive bacteria, including 104 strains of Staphylococcus aureus, 96 strains of Staphylococcus epidermidis and 7 strains of others. Gram negative bacteria (325 strains) were 172 strains of Klebsiella and 153 strains of Escherichia coli. The distribution of pathogenic bacteria in different gender and age groups (under 5 years old, 5-10 years old, and over 10 -14 years old) was calculated separately. The results showed that the distribution of pathogenic bacteria in female children under 5 years old (n=49 cases) was different from the total population: the infection of Gram-positive bacteria was higher than that of Gram-negative bacteria, and the proportion of Staphylococcus epidermidis was the highest (P<0.05). The distribution characteristics of children of other ages and sexes were consistent with the total distribution characteristics. The resistance rate of Gram-positive bacteria to penicillin, erythromycin and clarithromycin was high, while the resistance rate of Gram-negative bacteria to ampicillin, cefazolin and cefuroxime was high. The distribution characteristics were the same in children of different sex and age. Conclusion The pathogenic bacteria in children with lower respiratory tract infection in pediatric ward are mainly Gram-negative bacteria, and the main pathogenic bacteria have a high resistance rate to common drugs. The distribution of pathogenic bacteria in female children under 5 years old is unique: the infection of Gram-positive bacteria is higher than that of Gram-negative bacteria, and the proportion of Staphylococcus epidermidis is the highest, which deserves attention. The clinical drug sensitivity test can be used as an important reference for the treatment of drugs to guide the rational selection of antibiotics.
ABSTRACT
Objective:To summarize the clinical characteristics of neonatal cerebral infarction and its risk factors, so as to provide a reference for clinical diagnosis and early prevention of the disease.Methods:This study retrospectively analyzed the demographic data, clinical manifestations and brain imaging features of neonates with cerebral infarction ( n=45) admitted to the Department of Neonatal Critical Care Medicine of the Affiliated Children's Hospital of Xi'an Jiaotong University from June 2012 to July 2020. Ninety newborns without cerebrovascular disease matched for date of birth and gestational age were selected as the control. Two independent sample t-test, rank-sum test, Chi-square or corrected Chi-square test were used for univariate analysis and binary logistic regression were applied for analyzing the risk factors for neonatal cerebral infarction. Results:A total of 45 infants with clinically diagnosed neonatal cerebral infarction were enrolled, including eight small for gestational age and three macrosomia infants. The median age at disease onset was 1 d (1-2 d). There were 71% (32/45) presenting with convulsions as the first symptom, 4% (2/45) admitted with apnea and respiratory distress as the chief complaints, respectively,11% (5/45) having poor response and 9% (4/45) showing no obvious clinical manifestations. Cranial MRI and magnetic resonance angiography identified left hemisphere lesion in 25 cases (56%), right hemisphere lesion in 16 (36%) and both in four (9%). Thalamus and basal ganglia were involved in 11 cases. The lesions were supplied by middle cerebral artery [38% (17/45)], anterior cerebral artery ( n=1), posterior cerebral artery ( n=4), anterior and middle cerebral arteries ( n=4), middle and posterior cerebral arteries ( n=16), or anterior, middle and posterior cerebral arteries ( n=3). Univariate analysis showed that the proportions of small for gestational age [18% (8/45) vs 6% (5/90), χ 2=5.15], cesarean section after failure of trial of labor [18% (8/45) vs 1% (1/90), χ 2=10.85], meconium stained amniotic fluid [33% (15/45) vs 9% (8/90), χ 2=12.68], fetal distress [20% (9/45) vs 3% (3/90), χ 2=8.34] and neonatal asphyxia [16% (7/45) vs 2% (2/90), χ 2=6.56] were all higher in the infarcted infants than those in the control (all P<0.05). Binary logistic regression analysis revealed that small for gestational age ( OR=3.981, 95% CI: 1.075-14.742, P=0.039), cesarean section after failure of trial of labor ( OR=17.959, 95% CI: 2.032-158.698, P=0.009) and fetal distress ( OR=5.756, 95% CI: 1.129-29.331, P=0.035) were independent risk factors for neonatal cerebral infarction. Conclusions:Most neonates with cerebral infarction would have convulsions initially, while some are asymptomatic. Middle cerebral arteries are often involved in the lesion. The risk of this disease may be increased in small for gestational age infants, cesarean section after failure of trial of labor and fetal distressed cases.
ABSTRACT
Objective:To compare the efficacy of transcatheter arterial embolization (TAE) with laparotomy in the treatment of severe liver injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 48 patients with severe liver injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from December 2013 to June 2020, including 28 males and 20 females; aged 16-75 years [(45.7±6.2)years]. There were 25 patients with grade III, 15 grade IV and 8 grade V according to the American Association for the Surgery of Trauma (AAST) classification. After general treatments such as infusion and hemostasis, TAE was performed in 26 patients (TAE group) and laparotomy in 22 patients (laparotomy group). The operation time and length of hospital stay were compared between the two groups. Erythrocyte, hemoglobin and serum creatinine were compared before operation and at postoperative 1 day. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed before operation and at postoperative 1, 3, 7 days. Complications were observed.Results:All patients were followed up for 12-60 months [(17.1±9.1)months]. The operation time and length of hospital stay were (65.7±9.2)minutes and (21.6±6.6)days in TAE group, significantly shorter than (162.5±28.1)minutes and (31.5±7.4)days in laparotomy group ( P<0.05 or 0.01). There was no significant difference between the two groups referring to erythrocyte, hemoglobin and serum creatinine before operation and at postoperative 1 day (all P>0.05). There was no significant difference in ALT and AST between the two groups before operation (all P>0.05). TAE group showed ALT level of 1 154(884, 1 698)U/L, (975.3±400.9)U/L and (403.4±232.9)U/L at postoperative 1, 3, 7 days, significantly lower than 2 053(1 965, 2 132)U/L, (1 604.1±188.2)U/L and (915.3±160.5)U/L in laparotomy group (all P<0.05). TAE group showed AST level of (1 313.2±542.0)U/L, 525(302, 971)U/L and 174(84, 324)U/L at postoperative 1, 3, 7 days, significantly lower than (1 962.9±245.4)U/L, 1 478(1 089, 1 677)U/L and 837(674, 1 006)U/L in laparotomy group ( P<0.05 or 0.01). The complication rate was 26.9% (7/26) in TAE group, significantly lower than 59.1% (13/22) in laparotomy group ( P<0.05). Conclusion:For severe liver injury, TAE can significantly shorten operation time and length of hospital stay, accelerate the recovery of liver function and reduce the complication rate in comparison with laparotomy.
ABSTRACT
Intracerebral hemorrhage is one of the important stroke types. Most survivors of intracerebral hemorrhage will leave different degrees of neurological dysfunction, resulting in their poor outcomes. Studies have shown that C-reactive protein is associated with the outcomes of patients with intracerebral hemorrhage. This article reviews the predictive role of C-reactive protein in patients with intracerebral hemorrhage.
ABSTRACT
Objective:To investigate the pathogenesis and prognosis of transformation of primary myelofibrosis (PMF) to B-cell acute lymphoblastic leukemia (B-ALL).Methods:The diagnosis and treatment process of a patient transferred from PMF to B-ALL in Affiliated Tumor Hospital of Zhengzhou University in November 2018 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 64-year-old female, she was initially diagnosed with PMF, and then she developed B-ALL 17 months later after receiving treatment of prednisone, danazole, levamisole, aspirin, thalidomide and jaktinib. After induction therapy, the patient received 8 months of continuous remission, and then the reexamination showed relapse. There was no remission after reinduction therapy. The patient gave up treatment and was discharged 2 months later. JAK2 V617F gene mutation was positive before and after leukemia transformation.Conclusions:The patients with transformation of PMF to B-ALL have poor clinical prognosis and short survival time. The possible mechanism of its transformation may be related to additional genetic events or certain high-risk genes. However, the specific mechanism is still unclear, and further investigation of the etiology is needed to seek targeted treatment.
ABSTRACT
ObjectiveTo evaluate the methodological quality of traditional Chinese medicine （TCM） diagnosis and treatment guidelines/consensus of constipation with Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ）tool， and to study the attention situation of the included Chinese patent medicines in China's National Reimbursement Drug List in the guidelines/consensus. MethodThe data of CNKI，VIP，Wanfang Data，SinoMed，PubMed and Cochrane from the inception of the databases to October 2021 were searched to collect the TCM diagnosis and treatment guidelines/consensus of constipation. Then，the diagnosis and treatment standards and recommended Chinese patent medicines were extracted. Two researchers assessed the methodological quality of the guidelines/consensus with AGREE Ⅱ tool independently. The quality of reports was evaluated by Reporting Items for practice Guidelines in HealThcare （RIGHT） Statement. The recommended Chinese patent medicines in the guidelines/consensus were compared with those in the National Reimbursement Drug List. ResultEleven consensus and 2 guidelines were included，involving 794 experts. The scores of AGREE II were clarity of presentation（59.0%），scope and purpose（44.0%），stakeholder involvement（23.1%），rigor of development （12.1%），applicability （11.1%），and editorial independence （8.3%） from high to low. Five articles were recommended at B level（recommended after revision） and 8 articles were at C level （not recommended）. The average scores of RIGHT Statement were as follows：basic information （93.59%），background （57.69%），evidence （18.46%），recommendations （20.88%），review and quality assurance （19.23%），funding，declaration and management of interests （0.00%）， and other information （0.00%）. The included guidelines/consensus recommended a total of 27 Chinese patent medicines，among which 20 were included in the National Reimbursement Drug List，with 4 species of Class A and 16 species of Class B， accounting for 74.1% of all recommended Chinese patent medicines. Ten purgative Chinese patent medicines in the National Reimbursement Drug List were recommended by the guidelines/consensus，accounting for 50% of all purgative drugs， and 8 were not recommended. There were prescriptions for purgation， for promoting digestion and removing food stagnation， for clearing heat and purging fire，and for warming the middle and dissipating cold，Tibetan medicine and Mongolian medicine. ConclusionBy the AGREE Ⅱ assessment，the methodological quality of the TCM diagnosis and treatment guidelines/consensus of constipation included in this study needed to be improved in the future. The report quality evaluated with RIGHT Statement was low. Most drugs included in the National Reimbursement Drug List were paid attention in the TCM diagnosis and treatment guidelines/consensus of constipation. Moreover，the drugs included in the National Reimbursement Drug List could basically fulfill the clinical needs reflexed from the guidelines/consensus recommendations. However， the reasons of some drugs failing to be included in the National Reimbursement Drug List needed to be studied in the future.
ABSTRACT
OBJE CTIVE To provide reference for the adjustment and optimization of the policies related to traditional Chinese medicine（TCM）injection in China. METHODS The policies related to TCM injections issued at the national level were collected from Jan. 1，1990 to May 31，2021. Based on the perspective of policy tool ，the content analysis and quantitative analysis were used to classify ，code and analyze the policy terms according to “policy serial number-chapter number-specific terms ”. RESULTS & CONCLUSIONS Totally 30 policy documents related to TCM injection were included ， with a total of 389 codes. Environment-based policy tools were the most widely used （79.95％），followed by supply-oriented policy tools ，accounting for 15.42％. Demand-based policy tools accounted for the least proportion （4.63％）. Among environment-based policy tools ，the regulatory and control policy tools （38.05％） received more attention，and the policy publicity （2.06％） received fewer applications. Among supply-oriented policy tools ，there were more applications of science and technology support （10.80％）， and fewer applications of capital investment （0.26％）. Among demand- based policy tools ，organizational coordination was the most widely used （3.34％），followed by experience demonstration （1.29％），which had not yet involved the relevant policies of international exchange. In order to promote the development of TCM injection ，it is necessary to appropriately reduce the application of environment-based policy tools ，increase the application of policies such as policy publicity ，and improve the external environment for TCM injection ；optimize the internal combination of supply-oriented policy tools ，increase the use of capital investment tools ，and effectively play the role of policy boosting；emphasize the application of demand-based policy XJY21013） tools to form an effective policy pulling force for the healthy development of TCM injection.
ABSTRACT
Purpose@#SOX12 is overexpressed in many cancers, and we aimed to explore the biological function and mechanism of SOX12 in thyroid cancer. @*Materials and Methods@#We first analyzed the expression of SOX12 in thyroid cancer using data in The Cancer Genome Atlas. Immunohistochemistry and qRT-PCR were performed to identify SOX12 expression in thyroid cancer tissue and cells. Thyroid cancer cells were transfected with small interfering RNA targeting SOX12, and cellular functional experiments, including CCK8, wound healing, and Transwell assays, were performed. Protein expression was examined by Western blot analysis. A xenograft model was developed to evaluate the effect of SOX12 on tumor growth in vivo. @*Results@#SOX12 expression was increased in thyroid cancer tissue and cells. SOX12 promoted cell proliferation, migration, and invasion and accelerated tumor growth in vivo. The expression of PCNA, Cyclin D1, E-cadherin, Snail, MMP-2, and MMP-9 was affected by SOX12 knockdown. Bioinformatic analysis showed that SOX12 could interact with the POU family. SOX12 knockdown inhibited the expression of POU2F1, POU2F2, POU3F1 and POU3F2, and SOX12 expression showed a positive correlation with POU2F1, POU3F1, and POU3F2 expression in clinical data. POU2F1 and POU3F1 were able to reverse the effect of SOX12 knockdown on thyroid cancer cells. @*Conclusion@#SOX12 affects the progression of thyroid cancer by regulating epithelial-mesenchymal transition and interacting with POU2F1 and POU3F1, which may be novel targets for thyroid cancer molecular therapy.
ABSTRACT
Objective:To explore the effectiveness and safety of plasma exchange in the treatment of neonatal extremely severe hyperbilirubinemia.Methods:A retrospective analysis was performed on the data of 18 cases, who were all newborns with extremely severe hyperbilirubinemia and treated with plasma exchange in the NICU at Xi ′an Children′s Hospital from April 2019 to December 2019.The changes of serum total bilirubin, indirect bilirubin, albumin, white blood cells, red blood cells, platelets, hematocrit, hemoglobin, serum sodium, serum potassium, serum calcium, blood glucose, blood coagulation and mean arterial pressure were compared before and after plasma exchange.Results:A total of 18 eligible children were included.The peak value of total bilirubin was (571.2±113.3) μmol/L before treatment, and the value after treatment was (235.8±66.7) μmol/L, whose difference was statistically significant ( P<0.05). The exchange rate of bilirubin was (58.5±8.4)%.There were no statistically significant differences in the changes of white blood cells, platelets, hemoglobin, hematocrit, serum sodium, serum potassium, serum chloride, serum calcium, serum glucose, and albumin before and after plasma exchange (all P>0.05). There were no allergic reactions, hypotension, plasma separator or pipeline coagulation and other adverse reactions during plasma exchange. Conclusion:Plasma exchange therapy can remove serum bilirubin quickly, effectively and safely, and may be a new treatment for neonatal hyperbilirubinemia.
ABSTRACT
Objective:To explore the expression and clinical significance of IL-1β and IL-1β receptor antagonist(IL-1ra)in persistent pulmonary hypertension of the newborn(PPHN)secondary to sepsis.Methods:The newborns with sepsis were enrolled in the Department of Neonatal Intensive Care Unit(NICU)of Xi′an Children′s Hospital from January 2018 to November 2020.The newborns with sepsis were divided into two groups: the newborns without PPHN( n=108)were the control group and the newborns with PPHN( n=44)were the experimental group.Clinical data, laboratory examination and bedside echocardiography of all the newborns were collected to analyze the differences between the two groups.The expression levels of IL-1β and IL-1ra in neonatal plasma of the two groups were detected by enzym-linked immunosorbination(ELISA), and their roles in neonatal sepsis with PPHN were further analyzed.The risk factors of neonatal sepsis with PPHN were analyzed by multivariate Logistic regression, and the early prediction value of the risk factors for neonatal sepsis with PPHN were evaluated by the receiver operating characteristic(ROC)curve. Results:There were no significant differences in gestational age[(39.11±0.55)w vs(38.85±0.72)w], birth weight[(3.30±0.49)kg vs(3.24±0.55)kg]and proportions of males[60(55.6%)vs 30(68.2%)]between the two groups( P>0.05). The right ventricular diameter[(9.57±0.35)mm], pulmonary artery pressure[(51.36±5.91)mmHg]and the level of N-terminal brain natriuretic peptide(NT-proBNP)[(25436.83±12343.18)ng/L)]significantly increased in the experimental group than those in the control group[(8.77±0.41)mm, (31.24±5.11)mmHg, (11267.09±4405.48)ng/L, respectively, P<0.05]. Before treatment, the expression levels of plasma IL-1β[(31.24±5.25)ng/L]and IL-1ra[(41.94±10.13)ng/L]in the experimental group were significantly higher than those in the control group[(18.27±4.47)ng/L, (21.47±8.76)ng/L, respectively, P<0.05]. The expression levels of plasma IL-1β[(10.46±3.17)ng/L]and IL-1ra[(10.58±2.94)ng/L]in the experimental group after treatment were significantly lower than those before treatment[(31.24±5.25)ng/L, (41.94±10.13)ng/L , respectively, P<0.05]. Multivariate Logistic regression analysis showed that IL-1β and NT-proBNP were the independent risk factors for neonatal sepsis with PPHN( P<0.05). ROC curve analysis showed that IL-1β and NT-proBNP had the good predictive value for the occurrence of neonatal sepsis with PPHN( P<0.05). IL-1β combined with NT-proBNP has the better predictive value for neonatal sepsis with PPHN. Conclusion:IL-1β combined with NT-proBNP have the high predictive value for PPHN of the newborns secondary to sepsis.
ABSTRACT
Objective@#To analyze the impact of life satisfaction and parental rearing methods on accidental injuries of primary and secondary school students in rural areas, and to provide a therotical reference for injury prevention and intervention among primary and secondary school students in rural areas.@*Methods@#A stratified cluster random sampling method was used to select 2 045 rural primary and middle school students in Luliang County, Yunnan Province, questionnaire survey regarding injury, MSLSS and EMBU was administered.@*Results@#The incidence of accidental injury among rural primary and middle school students was 16.19 %, and the rate of boys (19.51%) were higher than that of girls (12.26%) ( χ 2=19.69, P <0.01). Multivariate Logistic regression analysis found that women, low injury risk behavior scores, and high life satisfaction scores were associated with less accidental injuries( OR =0.62, 0.98,0.81), while day to day school and father s overprotection were associated with more for accidental injuries( OR =1.50, 1.04, P <0.05).@*Conclusion@#Parents should pay more attention to children s safety education while creating a good living environment for their children, but they should pay attention to their own education methods to reduce accidental injuries.
