Objective To investigate the predictive value of serum oncogene[proliferation-related gene(C-myc),transformation gene(N-ras),silk/threonine kinase 1(PLK1),fibroblast growth factor 2(FGF2)]protein levels in patients with hepatitis B associated hepatocellular carcinoma(HCC)after hepatic arterial chemoem-bolization(TACE).Methods A total of 127 patients with hepatitis B-associated hepatocellular carcinoma ad-mitted to a hospital from July 2016 to January 2021 were selected and divided into death group and survival group according to the follow-up results.The serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels were determined by double-antibody sandwich enzyme-linked immunosorbent assay.Univariate and multivari-ate Cox analysis were used to analyze the risk factors of serum oncogene C-myc,N-ras,PLK1 and FGF2 pro-tein levels in patients with hepatitis B-associated hepatocellular carcinoma after TACE.The receiver operating characteristic curve was used to evaluate the prognostic value of the serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels,and the patients were divided into high expression group and low expression group ac-cording to the corresponding cutoff value.Kaplan-Meier survival curve was used to evaluate the prognosis of different serum oncogene C-myc,N-ras,PLK1 and FGF2 protein level.Results Multivariate Cox regression a-nalysis indicated that TNM stage Ⅲ to Ⅳ(HR=2.998,95％CI:1.239-7.257),portal vein metastasis(HR=3.737,95％CI:1.941-7.193),abdominal metastasis(HR=3.482,95％CI:1.709-7.097),Child-Pugh grade B(HR=2.587,95％CI:1.045-6.406),high serum oncogene C-myc protein level(HR=1.224,95％CI:1.090-1.374),high serum oncogene N-ras protein level(HR=1.218,95％CI:1.097-1.353),high serum oncogene PLK1 protein level(HR=1.237,95％CI:1.110-1.379)and high serum oncogene FGF2 protein level(HR=1.141,95％CI:1.060-1.228)were independent risk factors for the prognosis of hepatitis B-asso-ciated hepatocellular carcinoma patients after TACE(all P＜0.05).The overall survival rate of low expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level was significantly higher than that of high expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level,the difference was statistically significant(all P＜0.001).Conclusion Serum oncogene C-myc,N-ras,PLK1,FGF2 protein levels have predic-tive value for the prognosis of patients with HBV-related liver cancer after TACE.

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Objective To investigate the impact of different treatment options on lumbar function, pain intensity, and anterior vertebral height in elderly patients with thoracolumbar vertebral compression fractures. Methods The clinical data of 102 elderly patients with thoracolumbar vertebral compression fractures who completed 1-year follow-up were retrospectively analyzed. They were divided into conservative group (32 cases), percutaneous kyphoplasty (PKP) group (35 cases), and percutaneous vertebroplasty (PVP) group (35 cases) based on different treatment options. One year after treatment, the clinical efficacy and complications of the three groups were evaluated. The Visual Analogue Scale (VAS) score, Japanese Orthopedic Association (JOA) score, Cobb angle, and anterior vertebral height were compared before and 1 year after treatment among the three groups. Results The excellent and good rates of the PKP group and PVP group were higher than those of the conservative group (P < 0.05). There was no significant difference in the excellent and good rates between the PKP group and PVP group (P>0.05). There was no significant difference in occurrence of complications among the three groups (P>0.05). One year after treatment, the VAS scores of the three groups were lower than before treatment, and the JOA scores were higher than before treatment, and the VAS scores of the PKP group and PVP group were lower than those of the conservative group, and the JOA scores were higher than those of the conservative group (P < 0.05). The VAS score of the PKP group was lower than that of the PVP group, and the JOA score was higher than that of the PVP group (P < 0.05). One year after treatment, the Cobb angles of the three groups were smaller than before treatment, and the anterior vertebral heights were higher than before treatment, and the Cobb angles of the PKP group and PVP group were smaller than those of the conservative group, and the anterior vertebral heights were higher than those of the conservative group (P < 0.05). The Cobb angle of the PKP group was smaller than that of the PVP group, and the anterior vertebral height was higher than that of the PVP group, the difference in anterior vertebral height was greater than that of the PVP group (P < 0.05). Conclusion Compared with conservative treatment, surgery can improve the clinical efficacy of elderly patients with thoracolumbar vertebral compression fractures. PKP is superior to PVP in reducing pain of patients, improving lumbar function and Cobb angle, and anterior vertebral height. Moreover, it has better safety.

Objective: To compare the effectiveness of less invasive surfactant administration (LISA) and intubate surfactant extubation (INSURE) on respiratory distress syndrome (RDS) among premature infant, so as to provide insights into improving treatment effects and reducing complications of RDS among premature infants. Methods: A total of 71 premature infants with RDS in Anhui Provincial Maternity and Child Health Hospital were randomly assigned into the LISA and INSURE group, and pulmonary surfactant (PS) administration was carried out by LISA and INSURE with basic support therapy and respiratory support therapy. The general information, arterial blood gas analysis before and after treatment, respiratory support time and incidence of complications were collected and compared between the two groups. Results: There were 31 cases in the LISA group, with a gestational age of (29.81±0.99) weeks and 22 male cases, and 40 cases in the INSURE group, with a gestational age of (30.02±1.13) weeks and 26 male cases. There were no significant differences in basic characteristics (including gestational age, birth weight, gender, etc.) between the two groups (all P>0.05). After administration, the level of PaO2 was lower in the LISA group than in the INSURE group [(78.35±6.55) mmHg vs. (87.68±8.21) mmHg, P<0.05], the level of PaCO2 was higher in the LISA group than in the INSURE group [(43.03±6.34) mmHg vs. (38.68±9.69) mmHg, P<0.05], and the incidence of bronchopulmonary dysplasia was lower in the LISA group than in the INSURE group (48.39% vs. 72.50%, P<0.05). Linear regression analysis showed that with the duration of LISA administration increase (2-7 min), the minimum heart rate of premature infants increased linearly (β=13, P<0.05). Conclusions Compared with INSURE, LISA administration could slowly improve ventilation oxygenation, reduce hyperventilation and incidence of bronchopulmonary dysplasia among premature infants with RDS. The incidence of slow heart rate may be reduced by appropriately prolonging the administration duration.

Objective:To investigate the risk factors for the occurrence and poor in-hospital prognosis in patients with peripartum cardiomyopathy (PPCM).Methods:The clinical data of 35 patients with PPCM and 35 healthy pregnant women in Xuanwu Hospital, Capital Medical University and Beijing Friendship Hospital Affiliated to Capital Medical University from January 2003 to January 2022 were retrospectively analyzed. The personal histories, laboratory examination, imaging examination, cardiac function outcome, etc were collected. According to the left ventricular ejection fraction (LVEF) at discharge, the patients with PPCM were divided into in-hospital recovery group (LVEF≥50%, 18 cases) and prolonged disease group (LVEF<50%, 17 cases). Multivariate Logistic regression analysis was used to analyze independent risk factors of poor in-hospital prognosis in patients with PPCM.Results:Among 35 patients with PPCM, the age was (29.81 ± 5.37) years old, 17 cases (48.57%) complicated with gestational hypertension, 6 cases (17.14%) complicated with gestational diabetes mellitus, 24 cases (68.57%) of New York Heart Association (NYHA) cardiac function classification was Ⅲ to Ⅳ class, and 4 cases died (11.43%). The gestational age in patients with PPCM was significantly shorter than that in healthy pregnant women: (36.26 ± 4.27) weeks vs. (38.54 ± 4.59) weeks, the rates of multiple pregnancy and gestational hypertension were significantly higher than those in healthy pregnant women: 17.14% (6/35) vs. 2.86% (1/35) and 48.57% (17/35) vs. 11.43% (4/35), and there were statistical differences ( P<0.05 or <0.01). Compared with hospital recovery group, the patients in protracted disease group had shorter gestational age, larger left ventricular end-diastolic diameter, higher serum creatinine, C-reactive protein and amino-terminal pro-brain natriuretic peptide (NT-proBNP), worse NYHA cardiac function classification, and there were statistical differences ( P<0.05 or <0.01); but there were no statistical difference in LVEF at the first diagnosis and troponin I between two groups ( P>0.05). Multivariate Logistic regression analysis result showed that elevated creatinine was an independent risk factor for poor in-hospital prognosis in patients with PPCM ( OR = 4.554, 95% CI 1.536 to 13.684, P = 0.018). Conclusions:The gestational hypertension may be a risk factor for PPCM. The gestational hypertension, earlier onset time, enlarged left ventricular end-diastolic diameter, high NT-proBNP, high C-reactive protein, high creatinine and high cardiac function NYHA classification may be risk factors for poor in-hospital prognosis in patients with PPCM; and elevated creatinine is an independent risk factor for poor in-hospital prognosis in patients with PPCM.

Objective:To observe the incidence and risk factors of acute kidney injury (AKI) in patients with acute myocardial infarction (AMI), and explore the effect of AKI on the adverse cardiovascular events during hospitalization.Methods:The clinical data of 1 286 first-episode patients with AMI from December 2014 to December 2017 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. The basic information, laboratory test results and used drug were collected, the incidences of AKI and adverse cardiovascular events during hospitalization were recorded.Results:Among 1 286 patients with AMI, 113 cases had AKI, the incidence of AKI was 8.79%. There were statistical differences in gender composition, age, Killip classification>1 grade, hypertension, diabetes, smoking history, left ventricular ejection fraction (LVEF)<56%, baseline estimated glomerular filtration rate (eGFR)<71.5 ml/(min·1.73 m 2), global registry of acute coronary events score (GRACE score) ≥176 scores, hemoglobin<128 g/L, interleukin-6 (IL-6) ≥35.74 ng/L, brain natriuretic peptide (BNP) ≥981 ng/L, thrombolysis in myocardial infarction score (TIMI score) ≥5 scores, high-sensitivity C-reactive protein (hs-CRP) ≥8.44 mg/L, serum creatinine at admission ≥90 μmol/L, heart rate ≥75 times/min and contrast agent dosage/eGFR ≥1.92 between patients with AKI and patients without AKI ( P<0.01 or<0.05). Multivariate Logistic regression analysis result showed that diabetes, LVEF<56%, baseline eGFR< 71.5 ml/(min·1.73 m 2) and hs-CRP ≥8.44 mg/L were the independent risk factors of AKI in patients with AMI ( OR = 2.99, 0.38, 0.30 and 2.48; 95% CI 1.31 to 6.84, 0.16 to 0.88, 0.12 to 0.78 and 1.07 to 5.75; P = 0.010, 0.024, 0.013 and 0.035). The hospital mortality, incidence of adverse cardiovascular events during hospitalization and length of hospital stay in patients with AKI were significantly higher than those in patients without AKI: 11.50% (13/113) vs. 2.39% (28/1 173), 22.12% (25/113) vs. 8.40% (99/1 173) and (12±8) d vs. (10±6) d, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that AKI was the independent risk factors of death and adverse cardiovascular events during hospitalization in patients with AMI ( OR = 5.32 and 3.08, 95% CI 2.67 to 10.59 and 1.89 to 5.03, P<0.01). Conclusions:The incidence of AKI is high in patients with AMI, and previous diabetes history, LVEF<56%, eGFR<71.5 ml/(min·1.73 m 2), hs-CRP≥8.44 mg/L are the independent risk factors of AKI in patients with AMI. The occurrence of AKI after AMI can increase incidence of adverse cardiovascular events during hospitalization and hospital mortality, and prolong the hospital stay.

Objective:To explor the effects of mentalization-based family therapy (MBFT) on the emotions of anxiety and depression, reflective functions, and related brain regions of adolescents with depression.Methods:Thirty-two adolescent patients with depression were selected in Beijing Huilongguan Hospital.Among them, fifteen patients treated with conventional drugs were defined as the control group, the other seventeen patients served as the observation group.On the basis of routine drug treatment, patients in the observation group were treated with 1.5 h MBFT once a week, for a total of 3 months.Among them, 10 patients underwent resting functional magnetic resonance imaging(rs-fMRI) scans before and after the intervention.SPSS 23.0 was used for statistical analysis of scale evaluation data by using chi-square test and repeated-measure analysis of variance, and pairwise Pearson correlation was used to construct a brain network matrix for the MRI results.The patient's brain network matrix was put into Gretna to calculate, and then use repeated measures analysis of variance and t test for judgment. Results:(1)Repeated measurement analysis of variance showed, over time and group, before and after intervention, the group×time interactions of patients' reflective function, anxiety, depression were statistically significant ( F=5.113, 9.350, 5.264, all P<0.05). Further simple effect analysis showed, in the observation group, there were statistically significant differences in patients' anxiety ((55.09±14.35) vs (30.58±3.62)), depression ((61.58±16.81) vs (31.00±3.48)) before and after intervention (all P<0.01). There was no significant difference in reflective function ((8.71±0.51) vs (8.87±0.50) ) in the observation group before and after intervention( P> 0.05). The reflective function((8.92±0.33) vs (8.73±0.35)) and anxiety((50.67±13.88) vs (45.78±12.89)) scores of the control group were not statistically significant different before and after intervention(all P>0.05), and the depression scores of the control group before and after inter-vention((69.33±9.11) vs (50.94±7.99)) were statistically significant different( P<0.01). (2)rs-fMRI showed that, using the posterior parietal lobe and the medial prefrontal lobe as seed points, the group×time interactions with right inferior frontal gyrus, right fusiform gyrus, right superior temporal gyrus, left middle temporal gyrus and right superior frontal gyrus were statistically significant ( F=29.56, 20.63, 8.69, 9.49, 8.62, all P<0.05). The further simple effect analysis showed in the observation group, the pre-test was less than the post-test, and the difference was statistically significant( P<0.05). In the control group, there were not statistically significant differences in the functional connection strength before and after the test(all P>0.05). (3)The brain network analysis of 264 regions of interest (ROIs) in the whole brain showed that the number of modules in the observation group was less than that in the control group, and the difference was statistically significant ( t=-2.64, P=0.046). Conclusion:MBFT can improve the anxiety and depression of adolescent patients with depression.It enhances the functional link between mentalization related brain regions and the whole brain, and enhances the activity of the whole brain link to become more integrated.

Objective:To investigate the efficacy of personalized family doctor contract services on risk factors of atherosclerotic cardiovascular disease (ASCVD) in high-risk population.Methods:Ten matched-community health centers of Shenzhen Luohu district were divided into intervention group and control group by cluster randomiztion. Subjects with high risks of ASCVD were screened out as intervention group from contracted residents who visited these centers and had complete data of the China-PAR model from August 2018 to April 2019. The control group received conventional general family doctor contract services. The individualized management were given to the intervention group after fully understanding patients′ ideas, concerns, and expectations (ICE). After 2-year intervention, score changes of ASCVD risk factors within and between groups were compared.Results:A total of 571 patients were enrolled, including 288 in the intervention group and 283 in the control group. After 2 years of intervention, 7 and 18 were lost to follow-up in two groups, respectively. Finally, 281 in the intervention group and 265 in the control group were included in the study. At baseline, there was no significant difference in ASCVD scores between the intervention group and the control group [(13.33±3.54) vs. (13.09±3.54) points; t=0.84, P=0.403], and the scores in both groups decreased significantly after the intervention [(10.89±4.01), (11.62±4.11) points], while the intervention group decreased more significantly (both P<0.05). Among the risk factors at baseline, HDL-C and diastolic blood pressure in the intervention group were lower than those in the control group, and there were no significant differences in other factors between the two groups. After the intervention, the levels of total cholesterol, systolic blood pressure and diastolic blood pressure in the two groups decreased significantly, and the number of people taking antihypertensive drugs increased significantly ( P<0.001 and P<0.05); HDL-C decreased in the control group ( P=0.023). After the intervention, compared to control group the intervention group had a higher proportion of patients taking antihypertensive drugs, with lower systolic and diastolic blood pressure ( P<0.05). After the intervention, the increase rate of HDL-C in the intervention group was more than that in the control group, and the decrease rate was less than that in the control group (χ 2=6.65, P=0.036). Conclusion:Family doctor contract services can reduce the risk factors of ASCVD, and personalized family doctor contract services can further improve the effects in the prevention and control of ASCVD. However, the effects might be insignificant and inconsistent for the ASCVD risk factors with deeper management requirements or no specific management measures, which highlights the complexity and diversity of ASCVD prevention and control, calling for multi-level and multi-faceted thinking and exploration.
