Objective To explore the therapeutic effect of combining continuous venovenous hemofiltration (CVVH) with hemoperfusion (HP) on patients with septic shock.Methods A prospective study was conducted. Thirty-two patients with septic shock admitted to Changshu No.1 People's Hospital were enrolled, and they were divided into two groups according to random digits table. The observation group (17 cases) was given HP before CVVH, in the control group (15 cases), only CVVH treatment was carried out, and lasting for 5 days in both groups. The changes of pulse oxygen saturation (SpO2), central venous pressure (CVP), systemic vascular resistance index (SVRI), cardiac index (CI), extra-vascular lung water index (EVLWI) were observed before treatment and 5 days after treatment.Results Compared with those before treatment, the levels of SpO2, CVP, SVRI, CI were obviously elevated, and EVLWI was markedly decreased after treatment in two groups. Compared with those of control group, the degrees of improvement of above indicators in observation group were more prominent [SpO2: 0.966±0.035 vs. 0.939±0.036, CVP (mmHg, 1 mmHg = 0.133 kPa): 8.5±3.2 vs. 8.1±4.2, SVRI (kPa·s·L-1·m-2): 1 497.35±157.08 vs. 1 343.60±144.48, CI (mL·s-1·m-2): 120.36±15.34 vs. 106.69±12.33, EVLWI (mL/kg): 6.84±0.73 vs. 7.65±0.70, allP < 0.05].Conclusion Combing HP with CVVH for treatment of patients with septic shock can improve their prognosis more obviously than using CVVH alone.

Objective: To examine and analyze the nm23, p16 gene expression in gastric cancer tissure,and follow up patients 5 years to discuss the relationship between nm23 and p16 gene synergy expression and gastric cancer biological characteristic and prognosis.Methods: nm23 and p16 protein in gastric cancer tissue and control were detected by immunohistochemistry,and the patients had been followed up for 5 years. Results: In 84 samples of gastric cancer, nm23 positive rate was 46.43%, p16 was 44.05%, the positive rate of gastric cancer tissue and metastasitic lymph node was lower than that of normal control, normal tissue near cancer or benign polyp,and these two genes were related to the depth of tumor invasion and clinical stage.The mortality and recurrence-metastasis rate was higher in these low expression group, and had a shorter median survive period. Conclusion: Abnormal expression of nm23 and p16 gene plays a important role in gastric cancer recurrence and devolepment and may be one of markers for evaluating tumor biological behavior and prognosis.

Objective: To evaluate the prevalence and consistency of screening myopia, non-cycloplegic myopia and cycloplegic myopia in children and adolescents, and to provide references for exploring the factors affecting the consistency of different definition methods. Methods: A total of 3 868 children and adolescents aged 6 to 17 years from seven schools were included in a school based cross sectional study in Shandong Province in September 2020. The prevalence of screening myopia, non cycloplegic refraction, and cycloplegic refraction at different ages and all children and adolescents were analyzed. With cycloplegic spherical equivalent ≤-0.50 D as the gold standard for myopia, and Kappa test and area under the ROC curve were used to evaluate the consistency. Results: The prevalence of cycloplegic myopia and screening myopia were 36.7% and 38.3% among children and adolescents. The prevalence of non cycloplegic myopia was 62.4%, which was significantly higher than screening myopia and cycloplegic myopia two methods in primary and junior high schools. Among 3 868 subjects, there were 3 628 (93.8%) subjects with screening myopia and 2 862 (74.0%) subjects with non cycloplegic myopia who were consistent with the gold standard for myopia. The Kappa values of screening myopia and non cycloplegic myopia were 0.87 and 0.51, and the area under the ROC curve was 0.94 (95% CI =0.93-0.95) and 0.79 (95% CI =0.78-0.81). Compared with other groups, children and adolescents aged 8 to 17 years, in junior or high school, urban residence, better presenting distance visual acuity, and astigmatism ≤1.50 D had a higher consistency in the application of screening myopia ( P <0.05). Conclusion The consistency between screening myopia and cycloplegic myopia is high, and the consistency between non cycloplegic objective myopia is low.

Objective To investigate the effect of intravitreal injection of fibrillin-2(FBN2)recombinant protein on FBN2-deficient retinopathy.Methods Thirty-two SPF-grade C57BL/6J mice were randomly divided into 4 groups:nor-mal control group,negative control group,FBN2 knockdown group,and FBN2 recombinant protein group,with 8 mice in each group.The right eyes were taken as the experimental eyes.Mice in the normal control group did not receive any inter-vention,mice in the negative control group were intravitreally injected with 3 μL empty vector(1 mg·L-1),and mice in the FBN2 knockdown group and FBN2 recombinant protein group were intravitreally injected with 3 μL adeno-associated vi-rus(1 mg·L-1).After 4 weeks,mice in the FBN2 recombinant protein group were intravitreally injected with 3 μL FBN2 recombinant protein(1 mg·L-1).Then,electroretinogram(ERG)and optical coherence tomography(OCT)were used to measure the amplitude of Rod-b and Max-a waves and the changes in the retinal structure.Real-time quantitative poly-merase chain reaction(RT-PCR)and Western blot were used to detect changes in FBN2,microfibril-associated glycopro-tein 2(MAGP-2),collagen I(COL1)mRNA and protein expression in the mouse retina.Results The ERG findings showed that compared with the negative control group and normal control group,the amplitude of Rod-b and Max-a waves in the retina of mice in the FBN2 knockdown group and FBN2 recombinant protein group decreased(all P＜0.05);com-pared with the FBN2 knockdown group,the amplitude of Rod-b and Max-a waves in the retina of mice in the FBN2 recom-binant protein group significantly increased(both P＜0.05).The OCT findings showed that compared with the FBN2 knock-down group,the structure of the retinal pigment epithelium and the light reflex in the FBN2 recombinant protein group be-came more regular.The RT-PCR detection results showed that compared with the FBN2 knockdown group,the expression of FBN2 mRNA in the retinal tissue of mice in the FBN2 recombinant protein group significantly increased,while the ex-pression of COL1 and MAGP-2 mRNA significantly decreased(all P＜0.05).Western blot assay results showed that com-pared with the FBN2 knockdown group,the expression of FBN2 protein in the retinal tissue of mice in the FBN2 recombi-nant protein group increased significantly,while the expression of COL1 and MAGP-2 proteins decreased significantly(all P＜0.05).Conclusion Intravitreal injection of FBN2 recombinant protein can compensate for the endogenous deficiency of FBN2 in mice with FBN2-deficient retinopathy and achieve therapeutic effects by regulating COL1 and MAGP-2 expres-sion.

Objective:To investigate the expression of latent transforming growth factor-β-binding protein (LTBP), transforming growth factor-β (TGF-β), cyclin-dependent kinase 2 (CDK2) and cyclin D2 (CCND2) in fibrillin-2 ( FBN2) interfering induced mouse retinopathy. Methods:Twenty-seven 8-week-old C57BL/6J mice were randomly divided into normal control group, empty vector group and FBN2 interference group according to the random number table method, with 9 mice in each group.The normal control group was not treated.The empty vector group and FBN2 interference group were intravitreally injected with 3 μl empty vector and 3 μl adeno-associated virus (AAV) carrying the sh-FBN2 interference plasmid in the right eye, respectively.The structural and functional changes of the retina were detected at 4 weeks after injection by optical coherence tomography (OCT) and full-field electroretinography (ERG).The expression and distribution of FBN2 protein in the retina were detected by immunofluorescence staining.The mRNA and protein expression levels of FBN2, LTBP-1, TGF-β2, CDK2 and CCND2 in mouse retina were detected by real-time fluorescence quantitative PCR and Western blot.All experiments complied with the ARVO statement.The research scheme was approved by the Experimental Animal Ethics Committee of Shandong University of Traditional Chinese Medicine (No.2019036).Results:Four weeks after injection, the results of OCT examination showed that compared with normal control and empty vector groups, the retinal pigment cortex of the FBN2 interference group was irregular with high density reflection areas.Full-field ERG results showed that compared with normal control and empty vector groups, the amplitude of Rod-a, Rod-b, Max-a and Max-b waveforms in FBN2 interference group decreased, and the differences were statistically significant (all at P<0.05).The results of immunofluorescence staining showed that FBN2 was expressed in the whole retina, and the fluorescence intensity of FBN2 was weaker in FBN2 interference group than that in normal control and empty vector groups.The fluorescence intensity of FBN2 in normal control group, empty vector group and FBN2 interference group was 16.21±2.21, 15.57±3.63 and 5.32±1.06, respectively, with a statistically significant overall difference ( F=66.03, P<0.05).The fluorescence intensity of FBN2 protein in FBN2 interference group was significantly lower than that in empty carrier group and normal control group (both at P<0.05).Compared with normal control and empty vector groups, the relative expression levels of LTBP-1 and TGF-β2 mRNA and protein were significantly increased in FBN2 interference group, while the relative expression levels of FBN2, CDK2 and CCND2 mRNA and protein were significantly decreased, and the differences were statistically significant (all at P<0.05). Conclusions:The increase of LTBP-1 and TGF-β2 and the decrease of G1/S phase related proteins CDK2 and CCND2 are involved in the development of FBN2-deficient retinopathy.

Background Schizophrenia patients often face high level of stigma and low level of self-esteem,significantly hindering their recovery.Mindfulness-based intervention has proven be effective in reducing stigma and improving self-esteem.However,traditional mindfulness intervention typically involve high costs and require long-term professional involvement.Objective To explore the effects of blended mindfulness interventions on stigma and self-esteem in patients with stable schizophrenia,so as to provide references for reducing stigma,enhancing self-esteem and promoting recovery.Methods Patients receiving outpatient treatment at the Third Hospital of Daqing from June 2022 to January 2023,who met the diagnostic criteria for schizophrenia in the International Classification of Diseases,tenth edition(ICD-10)and were in a stable phase,were recruited for the study(n=84).According to the random number table method,participants were randomly assigned to study group and control group,with 42 cases in each group.Both groups received treatment with the second-generation antipsychotic medications,while the study group additionally received blended mindfulness intervention for 8 weeks,with sessions lasting 45～60 minutes,three times a week.Both groups were evaluated with Five Facet Mindfulness Questionnaire(FFMQ),Internalized Stigma of Mental Illness Inventory(ISMI)and Rosenberg Self-Esteem Scale(RSES)at baseline and after 8-week intervention.Covariance analysis was used to compare the FFMQ,ISMI and SES scores between two groups after 8-week intervention.Results After 8-week intervention,there were statistically significant differences between two groups in total FFMQ scores,as well as in the observation,acting with awareness,non-judgment and non-reactivity subscale scores(F=50.680,12.952,13.567,22.799,14.043,P<0.01).Statistically significant differences were observed in total ISMI scores,and in the alienation,stereotype endorsement,discrimination experience,stigma resistance and social withdrawal subscale scores(F=513.125,148.990,125.055,75.996,154.850,54.125,P<0.01).The difference in RSES scores between two groups was also statistically significant(F=19.478,P<0.01).Conclusion Blended mindfulness intervention may help improve the mindfulness and self-esteem in stable schizophrenia patients while reducing stigma.

Objective To evaluate the diagnostic value of MRI-measured fetal percent predicted lung volume (PPLV) for the prognosis of left congenital diaphragmatic hernia (CDH) in fetus. Methods Clinical data of 32 children who were admitted to Women and Children's Medical Center of Guangzhou from September 2012 to December 2017 for prenatally diagnosed left CDH were retrospectively analyzed. These children were divided into two groups, the survival group (n=24) and the death group (n=8), according to the postoperative outcomes at 30 days after CDH repair. Moreover, they were also divided into non-pulmonary hypertension (non-PH) group (n=20) and PH group (n=12), based on whether they suffered from PH or not. Clinical data such as gestational age, birth weight, Apgar score and PPLV values in different groups were compared with t- or Fisher's exact test. The receiver operating characteristic (ROC) curve of the MRI-measured fetal PPLV values of the 32 children was plotted. Results (1) Comparing with the death group, fetal PPLV was significantly higher [(39.5±2.5)% vs (20.4±2.1)%, t=4.27], the gestations on initial diagnosis of CDH was later [(31.6±4.2) vs (25.4±4.6) gestational weeks, t=3.40], Apgar score of the neonates at 5 min was higher (8.7±1.5 vs 5.7±3.8, t=3.26), and fewer cases of PH were reported in the survival group [16.7% (4/24) and 8/8], all P<0.01. The area under the ROC curve of PPLV values for mortality prediction was 0.930 (95%CI: 0.843-1.016, P<0.01). When the PPLV value was 28.55%, its sensitivity and specificity for death prediction in children with left CDH were 100% and 79%, respectively. (2) Comparing with the PH group, fetal PPLV was significantly higher [(41.7±2.6)% vs (23.0±2.0)%, t=4.98], the gestations on initial diagnosis of CDH was later [(32.3±3.4) vs (26.3±5.2) gestational weeks, t=3.81], neonatal Apgar score at 5 min was higher (8.6±1.4 vs 6.8±2.5, t=2.62) and death rate was lower [0(0/20) vs 8/12] in the non-PH group (all P<0.01). The area under the ROC curve of the PPLV values for predicting PH was 0.902 1 (95%CI : 0.800-1.004, P＜0.01). When the PPLV value was 33.67%, its sensitivity and specificity for PH prediction was 100% and 75%, respectively. Conclusions Prenatal MRI measurement of PPLV can be used to predict death or as a warning sign of PH in children with left CDH, which may provide evidence for prenatal evaluation and rational clinical decision-making.
