Objective: This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress. Methods: Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis. Results: The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029). Conclusion The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365

OBJECTIVE: To study the preventive and therapeutic effects of safflower water extract on systemic scleroderma (SSc) in mice and its mechanism. METHODS: Sixty BALB/C mice were randomly divided into the control group, model group, prednisone group and safflower low, middle, high dose groups, 10 mice in each group.The control group was injected with normal saline, and the other five groups were subcutaneously injected with bleomycin hydrochloride with 100 μl at the concentration of 200 μg /ml on the back, once a day for 28 days to establish the SSc models.At the same time, the control group and model group were treated with normal saline (10 ml/kg), the prednisone group was treated with prednisone 4.5 mg/kg (10 ml/kg), and the low, middle, and high dose safflower groups were treated with safflower at the doses of 1.5, 3, 6 g/kg (10 ml/kg), and all groups were treated for 28 days.After 28 days, all mice were decapitated. The blood samples and back skin of the BLM injection part were collected.After that, all the tissue slices were taken to measure the dermal thickness, and the content of hydroxyproline (HYP) in the skin tissues was detected by hydrolysis method.The contents of tissue growth factor (CTGF) and transforming growth factor-β (TGF-β ) in the skin tissues and the levels of interleukin-6 (IL-6) and interleukin-17 (IL-17) in serum were determined by ELISA. RESULTS: Compared with the control group, the dermal thickness of the model group was increased(P＜0.05), the contents of CTGF, TGF-β and HYP in the skin tissues and the levels of IL-6 and IL-17 in the serum of the model group were increased(P＜0.05); compared with the model group, the dermal thickness in the prednisone group and safflower groups was decreased (P＜0.05), the levels of CTGF, TGF-β and HYP in the skin tissues and the serum levels of IL-6 and IL-17 in the prednisone group and safflower groups were decreased (P＜0.05). CONCLUSION Safflower water extract can improve skin condition (or dermal thickness) in SSc mice, and its mechanism may be related to reducing immune inflammatory response.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

The aim of this study was to systematically evaluate the clinical efficacy of Tripterysium Glycosides Tablets( TGT) alone or in combination with methotrexate( MTX) in the treatment of rheumatoid arthritis( RA) based on the laboratory index criteria and to provide a basis for the clinical application of TGT against RA. Six databases including CNKI,Wan Fang,VIP,PubMed,EMbase and Cochrane were retrieved for randomized controlled trials( RCT) about TGT alone or combination with MTX in the treatment of RA.Then risk assessment tools were used for quality evaluation of the studies,and data extraction and analysis were conducted by using Rev Man 5.3 software for Meta-analysis. A total of 1 709 articles were retrieved,and finally 25 studies were included,with a total sample size of 2 507 cases. Meta-analysis results showed that between TGT alone and TGT alone,MDESR=-2. 66,95%CI[-8.17,2.86],P = 0.35; MDCRP=-2.38,95%CI[-9.01,4.24],P = 0.48; between TGT combined with MTX and MTX alone,MDESR= 8.74,95%CI[6.72,10.76],P<0.000 01; MDCRP= 5.37,95%CI[3.71,7.03],P<0.000 01; SMDRF= 1.05,95%CI[0.51,1.60],P = 0.000 1.The effect of TGT on decreasing CRP and ESR in RA patients was similar to the MTX. In addition,TGT combined with MTX were more effective in decreasing CRP,ESR,RF than MTX alone. However,due to the potential bias in the included studies,more and high-quality randomized controlled trials would be needed to improve the level of evidence.

To systematically review the improvement effects of Tripterygium Glycosides Tables( TGT) alone or in combination with methotrexate( MTX) on the clinical signs and symptoms of rheumatoid arthritis( RA),and provide a basis for the rational use of TGT in clinic,in the current study,six literature databases including CNKI,Wan Fang,VIP,PubMed,EMbase,and Cochrane Library,were systematically searched,according to the inclusion and exclusion criteria. Review Manager 5.3 software was used to input the literatures,and we assessed the risk bias on the level of outcome indicators for each included literature. A total of 18 literatures were included,and the classification results showed that: compared with MTX,TGT alone can reduce the number of joint swelling( MD =0. 18,95%CI[-1.06,1.42],P = 0.78) and joint tenderness( MD =-0.06,95% CI[-1.69,1.56],P = 0.94) in RA patients with the same effect as MTX. In terms of drug combination,TGT combined with MTX had an advantage over MTX alone in lessening the morning stiffness time( MD = 18. 24,95% CI[12. 64,23. 84],P < 0. 000 01) of RA,joint tenderness( MD = 2. 65,95% CI[1. 85,3. 44],P<0.000 01) and joint swelling( MD = 3.01,95% CI[2.09,3.39],P< 0.000 01). In conclusion,this Meta-analysis suggest that TGT alone was superior to MTX in improving joint swelling and tenderness in RA patients,TGT combined with MTX may improve the clinical manifestation of RA patients better than MTX alone.

Objective: To effectively reduce the concentration of poisons in cleanroom, protect the health of workers, realize the optimization and automatic control of the new return air device. And the influence of initial concentration, air volume, temperature and relative humidity of formaldehyde on the purification effect of the new return air device was explored. Methods: The purification effect of the new return air device installed with the activated carbon and the photocatalyst purification net or ordinary activated carbon purification network was tested in a 60 m³ simulated cleanroom. The concentration of formaldehyde was determined by solution absorption-phenol reagent spectrophotometry. Based on the single factor experiment to determine the combination of two purification nets. The effects of air volume, initial formaldehyde concentration, temperature and relative humidity on the purification effect of the new return air device were investigated by orthogonal test. Then, the performance parameters of the return air device to purify formaldehyde were determined. Results: The formaldehyde purification efficiency of the two types of purification nets in the new return air device was higher than that of the ordinary activated carbon purification network (P<0.05) . The combination of activated carbon and photocatalyst purification net has no effect on the formaldehyde purification efficiency of the return air device (P>0.05) . According to the direct analysis and variance analysis, air volume was the most sensitive factor (F value is 18.894, P<0.05) , followed by initial concentration (F value is 16.128, P<0.05) , while temperature and relative humidity have little effect (F value is 0.041 and 0.599, respectively, P>0.05) . LSD analysis showed that there was no significant difference in the purification efficiency of formaldehyde between 475 m³/h and 626 m³/h (P>0.05) . From the perspective of formaldehyde purification efficiency and energy saving, when the air volume is set to 475 m³/h, the new return air device has higher purification efficiency for high concentration of formaldehyde. Conclusion The new return air device consisting of activated carbon and photocatalyst purification net can play a good purification role in cleanroom with different temperatures and different humidity. Its formaldehyde purification efficiency is affected by air volume and initial concentration.

Objective: To evaluate the efficacy and safety of nifekalan (NIF) on cardioversion in atrial fibrillation (AF) patients post radiofrequency ablation, and investigate the relevant factors related to the cardioversion efficacy of NIF. Methods: We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval and QTc interval before the medication and at 5, 10, 20, 120 min after the medication. According to the drug outcome of NIF, patients were divided into conversion group and non-conversion group, related factors affecting conversion efficacy were evaluated using logistic regression analysis. Results: (1)A total of 116 patients were enrolled in the study (63 males and 53 females, mean age was (64±18) years). Among them, 72 patients were converted to sinus rhythm, and the overall successful rate was 62.1%. There were 84 patients with persistent AF, of which 50 cases (59.2%) were restored to sinus rhythm. There were 32 patients with paroxysmal AF, 22 cases (68.8%) of them were restored to sinus rhythm. The conversion time was 1.5 to 12 (6.8±3.4)min. (2) In 116 patients, the QT interval and QTc interval were significantly longer after medication than before the drug administration (P<0.01), and peaked at about 10th min, and restored to the level before drug administration at about 120th min. (3) There were 8 cases of bradycardia (6.9%), 3 cases of frequent and short ventricular tachycardia (2.6%). (4) The duration of atrial fibrillation was shorter and left atrial diameter was smaller in the cardioversion group than in the non-cardioversion group (both P<0.05). There were no significant differences in gender, disease history, atrial fibrillation type and structural heart disease between the two groups (P>0.05). (5) Multifactorial logistic regression analysis showed that the duration of atrial fibrillation (OR=0.980, 95%CI 0.966-0.994, P=0.004) and the left atrial diameter (OR=0.888, 95%CI 0.814-0.967, P=0.007) were the factors that influence the cardioversion efficacy of NIF on atrial fibrillation post ablation. Conclusions The total effective rate of NIF was 62.1% in patients witrh sustained AF post radiofrequency ablation, was 68.8% in patients with paroxysmal AF. Besides, NIF has the advantage of short conversion time and few adverse reactions. Left atrium diameter and AF duration were relevant factors that influence the efficacy of NIF of cardioversion in patients with sustained AF after radiofrequency ablation.

OBJECTIVE: To investigate the expression of miR-155 in patients with diffuse large B-cell lymphoma (DLBCL), and to explore the effect of transfection of miR-155 inhibitor on the biological characteristics of DLBCL cells. METHODS: A total of 76 patients with DLBCL treated in our hospital were selected from April 2013 to December 2017. In the same time, 40 cases of lymph node reactive hyperplasia (LNRH) were selected as control group. DB cells were cultured and divided into miR-155 inhibitor, negative control and blank groups. The expressions of miR-155 in DLBCL, negative and blank control groups were detected by using real-time PCR, the cell proliferation was detected by MTT assay, the apoptosis was detected by flow cytometry, and the cell migration and invasion were detected by Transwell assay. RESULTS: The relative expression level of miR-155 in tissues of DLBCL patients was significantly higher than that in tissne of controls (1.93±0.16 vs 1.01±0.09) (t=33.991, P=0.000). The expression level of miR-155 increased (P＜0.05) in DLBCL patients with LDH level abnormarity, BCL-2, MUM1, Ki-67≥50%, non-GC type, Ann Arbor stage III-IV, extranodal lesion number≥2 and IPI score 3-5. The relative expression level of miR-155 in the miR-155 inhibitor group was lower than that in the negative control group and the blank group (P＜0.05). The absorbance (A) values at 24, 48, 72 and 96 h of culture in the miR-155 inhibitor group were lower than those in the negative control group and the blank group (P＜0.05), while the apoptotic rate was higher than that in the negative control group and the blank group (P＜0.05). Both the migrating cells and invading cell number in the miR-155 inhibitor group were lower than those in the negative control group and the blank group (P＜0.05). CONCLUSION The miR-155 highly expresses in DLBCL tissue, which relates with tumor malignancy and invasion progression. The specific inhibition of miR-155 expression in DB cells can reduce cell proliferation, accelerate cell apoptosis, and inhibit cell migration and invasion.

OBJECTIVE: To explore the value of water swallow test(WST)and simple two-step swallowing provocation test(SSPT)in the diagnosis of aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease. METHODS:87 hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease were recruited from the First Affiliated Hospital of Guangzhou Medical University during the period between December 2014 to December 2015. RESULTS: The number of patients of grade1,2,3,4 and 5 of water swallow test successively were 44,39,4,0 and 0. Patients with positive aspiration by the first-step(water injection of 0.4 mL)and the second-step(water injection of 2.0 m L)were 16 and 0. Patients with positive aspiration by radionuclide imaging was 35. Comparison of radionuclide imaging, the rate of missed diagnosis applying water swallow test was high 37.3%(31/83). Both the water swallow test and simple two-step swallowing provocation test have poor consistency with radionuclide imaging in the diagnosis of aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease(McNemar consistency test P=0.00).CONCLUSION: There is a high rate of missed diagnosis applying water swallow test and simple two-step swallowing provocation test to diagnosis aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD),and combined use of multiple assessment methods can reduce the missed diagnosis rate of aspiration.
