ABSTRACT
Ferroptosis is a new type of cell death proposed in recent years,and its main characteristics are iron overload and lipid peroxidation.Ferroptosis is involved in the occurrence and development of non-alcoholic fatty liv-er disease(NAFLD).Iron overload can generate a large amount of reactive oxygen species through the Fenton reac-tion.Under the action of lipoxygenase,the unsaturated fatty acids on the liver cell membrane undergo lipid peroxi-dation,which induces liver cell death and leads to the occurrence of non-alcoholic fatty liver disease/non-alcoholic steatohepatitis.Blocking ferroptosis may provide one of the therapeutic strategies to protect liver cells.
ABSTRACT
Corona virus disease 2019(COVID-19)epidemic has been effectively controlled,but its related complications still cannot be ignored,especially the cardiovascular circulatory system is the active site of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Angiotensin-converting enzyme 2(ACE2)is a type Ⅰ transmembrane glycoprotein that is highly expressed in heart,kidney and testis.Spike protein of SARS-CoV-2 invades host cells by binding to the cell surface receptor ACE2.However,there are still many deficiencies in the clinical application of vaccines and drugs developed based on this target.As a molecular chaperone,cyclophilin A(CypA)promotes protein folding and T cell activation.CD147 is one of the most widely studied CypA receptors,and the interaction of CypA/CD147 plays an important role in the entry of SARS-CoV-2 into host cells.However,there are few reports on the invasion of SARS-CoV-2 into the cardiovascular system through the CypA/CD147 signaling pathway.Based on this,this article summarizes the previous research evidence and the research basis of the research group,and reviews the structure and function of CypA/CD147,the role of CypA/CD147 in cardiovascular disease,and the cardiovascular disease caused by SARS-CoV-2 targeting CypA/CD147 signal pathway,in order to provide reference for the diagnosis and treatment of the COVID-19 complicated with cardiovascular system diseases.
ABSTRACT
Objective To explore the predictive value of serum proprotein convertase subtilisin/kexin type 9(PCSK9)and proprotein convertase subtilisin/kexin type 9(CTRP6)in pregnant women undergoing threatened abortion and fetal protection treatment for pregnancy outcomes.Methods Eighty pregnant women with threatened abortion who were treated in the Second Affiliated Hospital of Shaanxi University of Chinese Medicine from August 2021 to May 2022 were selected as the study subjects.According to the pregnancy outcome,they were grouped into the good pregnancy outcome group(n=62)and the bad pregnancy outcome group(n=18),while another 60 pregnant women with normal pregnancy tests in the hospital were selected as the control group.The serum levels of PCSK9,CTRP6,progesterone and β-human chorionic gonadotropin(β-HCG)were measured by enzyme-linked immunosorbent assay(ELISA).Pearson method was applied to analyze the correlation between serum PCSK9,CTRP6 levels and progesterone and β-HCG levels.Multivariate Logistic regression analysis was applied to analyze the factors affecting the pregnancy outcomes of pregnant women with threatened abortion.The predictive value of serum PCSK9 and CTRP6 on pregnancy outcome of pregnant women with threatened abortion and pregnancy protection treatment was analyzed by the receiver operating characteristic(ROC)curve.Results The level of progesterone(45.65±3.48,38.29±3.54 and 31.56±4.11 nmol/L),β-HCG(32 056.56±4 244.54,23 642.32±3 897.67 and 11 375.56±3 454.35 mIU/L)and CTRP6(436.53±36.23,328.44±31.06 and 277.86±25.56 ng/ml)in control group,good pregnancy outcome group and bad pregnancy outcome group decreased gradually,while the level of PCSK9(64.22±10.35,82.24±13.33 and 114.56±17.67 ng/ml)in the control group,the good pregnancy outcome group and the bad pregnancy outcome group increased gradually,with statistically significant differences(F=129.231,199.334,244.007,111.297,all P＜0.05).Pearson method showed that serum PCSK9 was negatively correlated with progesterone and β-HCG levels(r=-0.545,-0.514,all P＜0.05),and serum CTRP6 was positively correlated with progesterone and β-HCG levels(r=0.567,0.496,all P＜0.05).Multivariate Logistic regression analysis showed that the high level of PCSK9 was an independent risk factor for pregnancy outcome of threatened abortion and fetal protection treatment,and the high level of CTRP6,progesterone and β-HCG were independent protective factors for pregnancy outcome of threatened abortion and fetal protection treatment(P＜0.05).ROC results showed that the area under the curve(AUC)of serum PCSK9 and CTRP6 levels for patients with adverse pregnancy outcomes in the prediction of threatened abortion and fetal protection treatment was 0.843 and 0.849,respectively.The AUC predicted by the combination of the two was 0.941,which was better than that predicted by each individual(Z=1.725,1.882,P＜0.05),with a specificity and a sensitivity of 85.48%,94.44%,respectively.Conclusion The serum PCSK9 level of pregnant women undergoing threatened abortion and fetal protection treatment was obviously increased,and the level of CTRP6 was obviously reduced.This study indicated both have important value in predicting the pregnancy outcomes of pregnant women undergoing threatened abortion and fetal protection treatment.
ABSTRACT
Objective To investigate the correlation between serum levels of prostaglandin-endoperoxide synthase 2(PTGS2),chitinase-3-like protein 1(CHI3L1)and cognitive impairment caused by cerebrovascular disease.Methods From October 2020 to October 2022,96 inpatients with cerebrovascular diseases admitted to the Third People's Hospital of Chengdu were regarded as the study subjects.The basic clinical data of the patients were recorded,the serum levels of PTGS2 and CHI3L1 were detected by enzyme-linked immunosorbent assay,and these patients were grouped into normal group(n=60)and impaired group(n=36)based on the presence or absence of cognitive impairment.The correlation between serum PTGS2 and CHI3L1 levels and fasting blood glucose(FBG)and homocysteine(Hcy)was analyzed by Pearson method.Logistic regression model was used to determine whether serum PTGS2 and CHI3L1 were independent risk factors for predicting cognitive impairment.Receiver operating characteristic(ROC)curve was drawn,and the predictive value of CHI3L1 and serum PTGS2 expression level in cognitive impairment in patients with cerebrovascular disease was analyzed according to the area under the curve(AUC).Results Compared with the normal group,the levels of serum PTGS2(29.30±9.46 pg/ml vs 17.86±5.40 pg/ml)and CHI3L1(13.04±4.06 pg/ml vs 7.51±2.66 pg/ml)in the disorder group were increased,and the differences were statistically significant(t=7.553,8.065,all P＜0.05).Multivariate Logistic regression analysis showed that FBG(OR=3.612,95%CI:2.324～5.614),Hcy(OR=2.584,95%CI:1.351～4.944),PTGS2(OR=1.964,95%CI:1.194～3.231)and CHI3L1(OR= 1.556,95%CI:1.023～2.367)were independent risk factors of cognitive impairment(all P＜0.05).PTGS2 was positively correlated with FBG and Hcy(r=0.368,0.551,all P＜0.05),and CHI3L1 was positively correlated with FBG and Hcy(r=0.510,0.376,all P＜0.05).The ROC curve showed that the area under curve(AUC)of PTGS2 and CHI3L1 in predicting cognitive impairment was 0.819 and 0.829,respectively.The AUC of the combined prediction of cognitive impairment was 0.902,which was obviously higher than that of the independent prediction of the two(Z =2.089,2.293;P=0.037,0.021),with sensitivity and specificity of 77.78%and 98.33%,respectively.Conclusion PTGS2 and CHI3L1 were highly expressed in the serum of patients with cognitive impairment of cerebrovascular disease,indicating that both were related to cognitive impairment of patients with cerebrovascular disease.

Objective To investigate the application of Rotarex mechanical thrombectomy system in lower extremity arterial thrombosis and to evaluate its clinical efficacy.Methods The clinical data of 61 patients(71 limbs,35 cases in acute phase,21 cases in subacute phase and 5 cases in chronic phase)with lower extremity arterial thrombosis treated with Rotarex were analyzed retro-spectively.Distal protective device was used in patients with poor distal artery outflow.High pressure saline was used during the pro-cedure and stent was used in patients with flow-limiting dissection.Catheter aspiration was performed in patients with distal artery embo-lization.Anticoagulant therapy was used in patients with thromboembolism and dual antiplatelet therapy was used in patients with in-situ thrombosis.Postoperative follow-up was performed with color Doppler ultrasound or computed tomography angiography(CTA)at 1 month,3 months and 6 months.Results Fifty-nine cases were treated with 6F Rotarex catheters and 2 cases were treated with 8F Rotarex catheters.Distal protective device was used in 10 cases,balloon dilation was performed in 49 cases and stent was used in 5 cases.Catheter aspiration was performed in 10 cases.Vessel rupture occurred in 4 cases,among whom 3 cases were successfully treated with the method of balloon compression and 1 case was treated with covered stent.Severe adverse events occurred in 4 cases and perioperative toe amputation was performed in 7 cases.Follow-up time was 3 to 6 months(mean 4.9 months).Lower extremity ischemic event occurred in 1 case at 6th month follow-up and was treated with stent.No other lower extremity ischemic events occurred in the course of follow-up.Conclusion For the treatment of lower extremity arterial thrombosis,Rotarex mechanical thrombectomy sys-tem has the advantages of minimally invasion,rapid and high efficiency.Combined with the therapy of catheter aspiration and stent place-ment,vascular patency can be further maintained and the lower extremity ischemic symptoms can be quickly relieved.
ABSTRACT
Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.

ABSTRACT
BACKGROUND:Polylactic acid has good biocompatibility and biodegradability,and has become a new orthopedic fixation material.However,the lack of cell recognition signal of this material is not conducive to cell adhesion and osteogenic differentiation,which limits its application in biomaterials. OBJECTIVE:3D-printed polylactic acid-nano-hydroxyapatite(nHA)/chitosan(CS)scaffold to evaluate its drug sustained-release and biological properties. METHODS:The porous polylactic acid scaffold(recorded as PLA scaffold)with interporous pores was printed by fused deposition modeling technique,and the scaffold was soaked in dopamine solution to prepare polylactic acid-dopamine scaffold(recorded as PLA-DA scaffold).Nano-hydroxyapatite was immersed in chitosan solution,and then the PLA-DA scaffold was immersed in it to prepare polylactic acid-nano-hydroxyapatite/chitosan scaffold(recorded as PLA-nHA/CS scaffold).The micro-morphology,porosity,water contact angle,and compressive strength of the three scaffolds were characterized.PLA-nHA/CS scaffold loaded with doxycycline(recorded as PLA-nHA/CS-DOX scaffold)was prepared by freeze-drying method,and its drug release was characterized.PLA,PLA-DA,PLA-nHA/CS,and PLA-nHA/CS-DOX scaffolds were co-cultured with MC3T3-E1 cells,separately,to detect cell proliferation and osteogenic differentiation.Staphylococcus aureus suspensions of different concentrations were co-cultured with four groups of scaffolds.The antibacterial performance of scaffolds was detected by inhibition zone test. RESULTS AND CONCLUSION:(1)Under scanning electron microscopy,the surfaces of PLA and PLA-DA scaffolders were dense and smooth,and nHA particles were observed on PLA-nHA/CS scaffolders.The porosity of PLA,PLA-DA and PLA-nHA/CS scaffolds decreased gradually,and the compressive strength increased gradually.The elastic modulus of PLA-nHA/CS scaffolds met the requirements of cancelous bone.The water contact angle of PLA-DA and PLA-nHA/CS brackets was smaller than that of PLA scaffolds.The PLA-nHA/CS scaffold sustainably released drugs in vitro for 8 days.(2)CCK-8 assay showed that the proliferation of MC3T3-E1 cells was not significantly affected by the four groups of scaffolds.The activity of alkaline phosphatase in PLA-DA group,PLA-nHA/CS group,and PLA-nHA/CS-DOX group was higher than that in PLA group.Alizarin red staining showed that compared with PLA group,the cells in PLA-nHA/CS group and PLA-nHA/CS-DOX group showed higher mineralized water level.(3)Inhibition zone test exhibited that PLA and PLA-DA scaffolds had no antibacterial properties.PLA-nHA/CS scaffolds had certain antibacterial properties.PLA-nHA/CS-DOX scaffolds had super antibacterial properties.(4)The results showed that the PLA-nHA/CS-DOX scaffold had good drug release performance,cell compatibility,osteogenic properties,and antibacterial properties.
ABSTRACT
Objective To investigate the factors that lead to diffuse chorioretinal atrophy(DCA)in patients with high myopia(HM)and to establish a prediction model.Methods In this retrospective case-control study,a total of 169 HM patients(338 eyes)admitted to the Department of Ophthalmology,Harbin 242 Hospital from October 2018 to October 2022 were selected.All patients underwent comprehensive ophthalmic examination at the time of inclusion.The incidence of DCA was evaluated according to the International Photographic Classification and Grading System for myopic maculopa-thy,and the risk factors of DCA in HM patients were analyzed by multivariate Logistic regression.The predictive model of DCA in HM patients was established by the receiver operating characteristic curve(ROC)based on risk factors,and the calibration degree of the predictive model was tested by Hosmer-Lemeshow(H-L).Results Among the 169 patients,34 patients were divided into the DCA group,and 135 patients were divided into the non-DCA group;there were statistically significant differences in age and gender distribution between the two groups(both P＜0.05).The axial length(AL),pat-tern standard deviation(PSD),positive rate of carbonic anhydrase 2(CAII)antibody in the DCA group were higher than those in the non-DCA group,while the best corrected visual acuity(BCVA),mean defect(MD)of the visual field,spheri-cal equivalent(SE),deep retinal microvessel density(MVD)and serum 25-hydroxyvitamin D[25(OH)D]were lower than those in the non-DCA group(all P＜0.05).Older age,longer AL and positive CAII antibody were the risk factors for DCA in HM patients(all P＜0.05),while greater deep retinal MVD and higher 25(OH)D were the protective factors(both P＜0.05).ROC analysis showed that the area under the curve of the prediction model for DCA in HM patients was 0.864(95％CI:0.802-0.911,P＜0.001),and the sensitivity and specificity were 85.29％and 88.15％,respectively.According to the H-L test,the prediction model for DCA in HM patients was relatively consistent with the actual results(P＞0.05).Con-clusion The occurrence of DCA in HM patients is affected by age,AL,CAII antibody,deep retinal MVD and 25(OH)D level,and a prediction model established based on the above factors can predict the risk of DCA well.

ABSTRACT
Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.
ABSTRACT
Gastrointestinal graft versus host disease is one of the most severe complications after hematopoietic stem cell transplantation, which can occur in patients of any age groups. Its clinical manifestations include nausea, vomit, abdominal pain, diarrhea and the like. Severe gastrointestinal graft versus host disease could directly influence the patients' clinical prognosis and therapeutic efficacy of transplantation. Here we had a review of the research progress on nutritional support and diet management strategies for gastrointestinal graft versus host disease. It is of great clinical significance to form a step-wise nutritional support model to reduce the risk of malnutrition in patients with gastrointestinal graft versus host disease, which would contribute to improving patients' general condition, relieving digestive tract symptoms, and reducing the risk of complications.

ABSTRACT
Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.
ABSTRACT
Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost
ABSTRACT
Objective:To explore the clinical characteristics and related socio-demographic factors of schizo-phrenia patients with different ages of onset.Methods:Totally 2 016 patients with schizophrenia aged 15 to 70 were selected according to the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition.All of the patients were interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview to diagnose schizophrenia,Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)and the Positive and Negative Syndrome Scale(PANSS)to assess symptoms.The cut-off points were 18 and 25 years old for three age groups,i.e.early onset(EOS),youth onset(YOS)and adult onset(AOS).Statistical analy-ses were performed by analysis of variance Pearson correlation analysis,and multivariate linear regression.Results:The early-onset patients had the highest total PANSS score(73.8±28.0)and CRDPSS score(11.7±5.4).Fe-male gender,high education level,Han ethnicity,early onset age,and slower onset of illness were negatively corre-lated with the total and dimension score of PANSS scale and CRDPSS scale(standardized regression coefficient:0.04-0.47),and income level and smoking were negatively correlated with those score(standardized regression coefficient:-0.04--0.14).Conclusion:Early-onset schizophrenia patients have more severe symptoms,and fe-male,high education level,early-onset disease,and chronic onset are the risk factors of symptom severity in patients with schizophrenia.

ABSTRACT
Objective:To compare demographic characteristics,clinical characteristics,therapeutic characteris-tics and physiological indicators of patients with bipolar Ⅰ disorder and bipolar Ⅱ disorder.Methods:A total of 381 patients with bipolar disorder(BD)diagnosed by the Diagnostic and Statistical Manual of Mental Disorders 5 th Edi-tion(DSM-5)were selected,including 302 patients with BD-Ⅰ(79.27％),74 patients with BD-Ⅱ(19.42％)and 5 patients with other specific and related disorders(1.31％).Demographic and clinical characteristics were collected with self-designed clinical information questionnaire.Multivariate logistic regression and multivariate linear regres-sion analysis were used for analysis.Results:Compared with patients with BD-Ⅱ,patients with BD-Ⅰ had more risk to have psychotic features(OR=5.75,95％CI:2.82-11.76),longer disease duration,and more repeated transcra-nial magnetic therapy(OR=3.09,95％CI:1.02-9.35),higher uric acid,total cholesterol and high-density lipo-protein.BD-Ⅰ in Han nationality was more common(OR=11.50,95％CI:1.76-75.30),and had lower education level(OR=10.22,95％CI:1.16-89.77),and less family history of psychosis(OR=2.34,95％CI:1.01-5.42).Conclusion:There are significant differences between BD-Ⅰ and BD-Ⅱ in demographic and clinical charac-teristics,treatment status,and physiological indicators,which could provide clues for exploring the pathogenesis of bipolar disorder.
ABSTRACT
Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Objective:To investigate the associated factors of depressive symptoms among patients with neo-plasms.Methods:Nationwide(excluding Hong Kong,Macao,and Taiwan),30 505 residents were selected by a combination of stratified sampling and quota sampling according to the proportion of the seventh national population census.Patient Health Questionnaire-9(PHQ-9),General Anxiety Disorder-7(GAD-7),self-made questionnaire,and simplified perceived social support scale used to evaluate depressive symptoms,anxiety symptoms,behaviors,and perceived social support among patients with neoplasms.Results:Totally 359(1.2％)patients with self-repor-ted clinically diagnosed neoplasms were included,of which 151(42.1％)patients with malignant neoplasms and 208(57.9％)patients with benign neoplasms.The detection rate of depressive symptoms in patients with neo-plasms was 76.6％.Less than three days of walking for more than 10 minutes per day in the past week(OR=6.63),4-6 days of walking for more than 10 minutes per day in the past week(OR=5.00),the low(OR=4.80)or medium(OR=3.06)overall sleep quality,the lower perceived friend support(OR=4.66),and anxiety symp-toms(OR=1.74)among patients with neoplasms were risk factors for depressive symptoms.Conclusion:Patients with neoplasms generally might be at a high risk of depressive symptoms,especially for those patients with less ex-ercise,poor sleep quality,and low perceived social support.
