ABSTRACT
Objective:To analyze the interaction between obesity and diabetes, obesity and central obesity, central obesity and diabetes on hypertension.Methods:A questionnaire survey on 7 622 residents of Han Chinese ethnicity, aged 35-75 years, of Liangzhou district of Wuwei city were performed using multi-stage random sampling method in September to December 2018. Relative excess risk due to interaction, attributable proportion, synergy index, and 95% CI of the three were used to evaluate the additive interaction. Logistic regression analysis was used to analyze the multiplicative interaction. Results:Among the 7 622 residents, hypertension was detected in 3 212 residents, with a crude prevalence rate of 42.14% and a standardized incidence of 33.81%. There was a significant difference in incidence of hypertension between residents of different sexes, between residents at different ages, between obese residents and normal weight residents, between residents who had central obesity and those who had no central obesity, between residents who smoked and those who did not, between residents of different family economic situations, between residents who had different occupations, and between residents who had diabetes and those who had no diabetes (all P < 0.05). Getting primary, middle, and high school education was a protective factor against hypertension, while obesity, central obesity, diabetes, male gender, age greater than 45 years were the risk factors for hypertension. Multivariate logistic regression analysis showed that there was no additive interaction between obesity and diabetes, obesity and central obesity, central obesity and diabetes on hypertension. There was a multiplicative interaction between obesity and central obesity on hypertension ( P = 0.031, 95% CI: 0.53-0.97) and the interaction was antagonistic, but there were no multiplicative interaction between obesity and diabetes, central obesity and diabetes on hypertension. Conclusion:There was a negative multiplicative interaction between obesity and central obesity on hypertension.
ABSTRACT
【Objective】 To investigate the role and mechanism of dapagliflozin (Dapa), a sodium glucose co-transporter 2 inhibitor, in acute liver injury. 【Methods】 Eight-week-old C57BL6/J mice were given a single intraperitoneal injection of CCl4 to induce acute liver injury. The mice were preventively given 5 mg/kg Dapa by gavage 24 h and 2 h before CCl4 injection, while those in the control group were given an equal volume of solvent gavage. After 24 h, the mice were anesthetized and sacrificed. H&E staining, plasma biochemistry, RT-qPCR, and Western blotting were used to detect the severity of liver injury and the expressions of macrophage-related genes. 【Results】 In the CCl4 group, hepatic infiltration of inflammatory cells increased, and liver and renal functions significantly deteriorated, which was further aggravated by Dapa. CCl4 could promote the expressions of M1 macrophages and fibrosis-related genes in the liver, but reduce those of M2 and antioxidant-related genes, and the latter was further inhibited by Dapa. In addition, the protein expression of arginase 1 decreased and that of SGLT2 increased after Dapa intervention, while NF-κB pathway did not change significantly, suggesting that Dapa might directly affect the energy metabolism homeostasis in the liver and aggravate acute liver injury induced by CCl4. 【Conclusion】 Dapa can exacerbate hepatic and renal damage in acute stage of liver injury, inhibit macrophages M2 polarization, and aggravate oxidative stress and inflammatory injury induced by CCl4.
ABSTRACT
Objective:To explore the risk stratification and prognostic significance of loss of chromosome Y (LOY) in patients with multiple myeloma (MM).Methods:The clinical data of 193 male patients with newly diagnosed MM admitted to Zhongshan Hospital of Fudan University from January 2018 to January 2020 were analyzed retrospectively and divided into a normal karyotype group(178) and a LOY karyotype group (15) according to the results of their primary conventional cytogenetics. Rank sum test, 2×2 chi-square test and independent sample t-test were used to compare laboratory findings, such as liver and kidney function, immunohistochemistry and cytogenetics, treatment efficacy and survival prognosis, between the two groups. The clinical prognostic significance of LOY was summarized through survival analysis and Cox regression. Results:Among the newly diagnosed male MM patients, 8%(15/178) were confirmed with LOY cases. The proportion of patients with Revised International Staging System(R-ISS) stage Ⅲ was significantly higher in the LOY group (8/15) than that in the normal karyotype group (40/178)(χ 2=7.052, P<0.01). A higher proportion of 1q21 amplification also occurred in the LOY group (10/13 vs 77/162)(χ 2=4.159, P<0.05). The proportion of complete response(CR)/stringent complete response(sCR) in the normal karyotype group after the fourth chemotherapy (63/171) was significantly higher than that in the LOY group (1/15)(χ 2=5.564, P<0.05). The proportion of progressive disease (PD) was lower in the normal karyotype group (16/171 vs 4/15) (χ 2=4.306, P<0.05). The 2-year progression-free survival (PFS) of MM patients for the LOY group was significantly shorter compared to that for the normal karyotype group ( Z=?3.201, P<0.01). Univariate survival analysis showed that PFS was significantly shorter in newly diagnosed MM patients with Creatinine(Cr)≥93 μmol/L, β 2-microglobulin (β 2-MG)≥4.0 mg/L, serum free light chain(sFLC)<0.06, bone marrow plasma cells (BMPC)≥30%, R-ISS stage Ⅲ, failure to achieve CR/sCR after the fourth chemotherapy, with LOY, 1q21 amplification, P53 deletion and t(4;14) ( P<0.05). Cox regression analysis showed that Cr≥93 μmol/L( HR=4.460, 95% CI 1.615-12.314, P=0.004), sFLC<0.06( HR=2.873, 95% CI 1.206-6.849, P=0.017), failure to achieve CR/sCR after the fourth chemotherapy( HR=3.522, 95% CI 1.437-8.634, P=0.006)and with LOY( HR=3.485, 95% CI 1.473-8.249, P=0.006)were independent risk factors for PFS in newly diagnosed MM patients. Conclusions:LOY is an independent risk factor for poor prognosis. It is important for the clinical outcome and prognosis of patients with newly diagnosed MM, and may become a novel clinical assessment indicator.
ABSTRACT
Objective To investigate the role and mechanism of action of Scabiosa atropurea in inhibiting the proliferation of hepatic stellate cells using cell experiment. Methods A total of 20 Wistar rats were randomly divided into control group and administration group, with 10 rats in each group. The rats in the control group were given normal saline by gavage, and those in the administration group were given Scabiosa atropurea by gavage to prepare drug-containing serum. HSC-T6 cells were incubated with the serum from the control group (10%) or the low-, middle-, and high-dose serum containing Scabiosa atropurea (10%, 15%, and 20%, respectively). MTT assay was used to observe the effect of different drug concentrations on cells in different periods of time; flow cytometry was used to measure cell apoptosis; qRT-PCR and Western blot were used to measure the mRNA and protein expression levels of fibrosis markers (α-SMA, collagen Ⅰ) and PI3K/Akt signaling pathway-related factors in hepatic stellate cells (HSCs). A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t - test was used for further comparison between two groups. Results Compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had a significant reduction in the OD value of cells (all P < 0.05) and a significant increase in the overall apoptosis rate of cells (all P < 0.05). The results of qRT-PCR showed that compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had significant reductions in the mRNA expression levels of α-SMA, collagen Ⅰ, PI3K, and Akt and a significant increase in the mRNA expression level of PTEN (all P < 0.05); Western blot showed that compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had significant reductions in the protein expression levels of α-SMA, collagen Ⅰ, PI3K, Akt, and p-Akt and a significant increase in the protein expression level of PTEN (all P < 0.05). Conclusion The Mongolian medicine Scabiosa atropurea can inhibit the proliferation of HSC-T6 cells and promote their apoptosis, possibly by regulating fibrosis markers and the PI3K/Akt signaling pathway to exert an anti-liver fibrosis effect.
ABSTRACT
Objective:To study the role of SUMOylation in the process of therapeutic hypothermia on neural stem cells (NSCs) in neonatal hypoxic-ischemic encephalopathy.Methods:SUMOylation is an essential post-translational modification involving small ubiquitin-like modifiers (SUMOs). Primary-cultured NSCs from mice were assigned into four groups: control group, hypoxia group, hypothermia group and hypoxia+hypothermia group. Western Blot was used to detect the protein levels of SUMO2/3, hypoxia-inducible factor-1α (HIF-1α), peroxisome proliferator-activated receptor γ coactivator factor 1α (PGC-1α) and octamer binding transcription factor 4 (Oct4). The diameters of NSCs were compared. ELISA was used to detect lactate dehydrogenase (LDH) level. Apoptosis was examined using flow cytometry. Immunofluorescence method was used to measure the differentiation of NSCs into neuronal cells.Results:Compared with the control group, the levels of SUMO2/3, HIF-1αand PGC-1α in NSCs of the hypoxia group increased 33%, 126% and 140%, respectively ( P<0.05). Compared with the control group, the levels of SUMO2/3 and PGC-1α in NSCs of the hypothermia group increased 52% and 536%, respectively ( P<0.05). Compared with the hypoxia group, the levels of SUMO2/3, HIF-1α, PGC-1α and Oct4 in the hypoxia+hypothermia group increased 44%, 40%, 230% and 59%, respectively ( P<0.05). The diameters of NSCs in hypoxia group, hypothermia group and hypoxia+hypothermia group were smaller than control group, and hypoxia+hypothermia group smaller than hypoxia group ( P<0.05). No significant differences existed in LDH levels between hypothermia group and control group ( P>0.05). LDH level in hypoxia+hypothermia group were significantly lower than hypoxia group ( P<0.05). No significant differences existed in the cell death rates between hypothermia group and control group ( P>0.05). The cell death rate in hypoxia+hypothermia group was significantly lower than hypoxia group ( P<0.05). Compared with the control group, the expressions of Nestin in both hypoxia group and hypothermia group were increased, but neuron specific enolase (NSE) were decreased ( P<0.05). Compared with hypoxia group and hypothermia group, the level of Nestin in hypoxia+hypothermia group was further increased, while NSE was further decreased ( P<0.05). Conclusions:Therapeutic hypothermia may increase the tolerance of NSCs to hypoxia by enhancing SUMO modification of proteins, providing theoretical basis for the treatment of hypoxic-ischemic encephalopathy with therapeutic hypothermia.

ABSTRACT
Objective:To investigate the expression of four cancer stem cell (CSC) markers (EpCAM, CD133, CD90 and CD24) in hepatocellular carcinoma tissues and peripheral blood circulating tumor cells (CTC),their value in the prognosis of patients with hepatocellular carcinoma.Methods:A total of 50 hepatocellular carcinoma tissues and 29 peripheral blood sample from 50 patients with hepatocellular cancer treated in Zhongshan Hospital Fudan University from October 2013 to September 2014 were collected and analyzed by flow cytometry or qRT-PCR to examine the expression of EpCAM, CD133, CD90 and CD24. The clinical data of patients were collected, including tumor size, tumor number, satellite lesions, vascular invasion, Edmondson stage, BCLC stage and liver cirrhosis, etc. The correlation between the expression of four markers in hepatocellular carcinoma tissues and CTC with the clinical data and survival time of patients were compared.Results:The positive expression rates of EpCAM, CD133, CD90 and CD24 in hepatocellular carcinoma tissues were 66% (33/50), 18% (9/50), 60% (30/50) and 56% (28/50); the positive expression rates in CTC were 55% (16/29), 38% (11/29), 31% (9/29) and 59% (17/29). CD90 expression in hepatocellular carcinoma tissue was positively correlated with the occurrence HCC liver cirrhosis ( P<0.05), while CD133 expression was negatively correlated with the 5-year survival rate of patients ( P<0.05). The expression of EpCAM and CD24 in peripheral blood CTC were closely related to the patient′s Edmondson stage ( P<0.05). The survival time of patients with CD133 positive expression in hepatocellular carcinoma tissue was lower than those without CD133 expression ( P<0.05); the survival rate of patients with EpCAM expressed in either tissue or peripheral blood CTC was lower than that of patients with EpCAM double negative expression ( P<0.05). The survival rate of patients with CD90 negative in HCC tissue and positive in peripheral blood was lower than that in patients with double negative/double positive in tissue and peripheral blood or patients positive in hepatocellular carcinoma tissue and negative in peripheral blood ( P<0.01). Conclusion:Different expression characteristics of four markers in cancer tissues and peripheral blood CTC might provide useful information about predicting prognosis of hepatocellular carcinoma. The expression of CD133 in tissues can be used as an important survival predictor of hepatocellular carcinoma patients. The differential expression of cancer markers in tissue samples and blood samples can provide more clinical prognostic information.

ABSTRACT
OBJECTIVE：To i nvestigate the clini cal ch aracteristics of anaphylactic shock induced by piperacillin and its compound preparation ，and to provide reference for prevention and treatment of the severe ADR. METHODS ：A case of anaphylactic shock induced by piperacillin and sulbactam were analyzed in our hospital ，meanwhile ADR literatures about piperacillin alone and its compound preparation-induced anaphylactic shock were collected from Medline ，CNKI，Wanfang database and VIP during the inception to Jul. 2020. Gender and age of patients ，allergic history ，primary disease and treatment ，skin test ， administration route and dosage of piperacillin and its compound preparation ，occurrence time and main manifestations of anaphylactic shock ，treatment measure and prognosis were analyzed ，then prevention and treatment suggestions were put forward. RESULTS：The patient in this case was transferred to the ICU after partial hepatectomy. The use of piperacillin and sulbactam to prevent postoperative infection caused anaphylactic shock. A total of 28 literatures about anaphylactic shock induced by piperacillin and its compound preparations were collected from the database （involving 28 patients）. Among totally 29 patients，there were 12 male and 17 female；the majority of patients were 50-59 years old （6 cases，20.69％）. Three patients had allergic history （food， latex gloves ，etc.），and most of the primary diseases were infectious diseases or the drug used in perioperative period. Skin tests were carried out in 22 patients（75.86％）before medication and the results were negative. The possible allergenic drugs of 27 cases which were administered by intravenous route included piperacillin ，piperacillin sulbactam and piperacillin tazobactam. The dosage was different according to the primary disease and severity. 14 patients（55.56％）developed anaphylactic shock within 5 minutes after drug exposure. The main symptoms were systemic allergic reaction ，mainly involving the circulatory system. Except for two death cases ，the other patients ’symptoms were relieved after treatment. CONCLUSIONS ：Allergic history and skin test results may have limitation in predicting anaphylactic shock induced by piperacillin and its compound preparation. Close monitoring needs to be taken in patients during these medications. Rescue therapy should be prepared in advance and countermeasures need to be carried out promptly in case of anaphylactic shock.

The source and type of strains were analyzed, and antifungal drug sensitivity tests were performed by using the micro-dilution method. Whonet 5.6 and SPSS 22.0 were applied to analyze the data.Results:The overall main strains were Candida albicans (38.74%, 399/1 030), Candida tropicalis (16.99%, 175/1 030) and Candida parapsilosis (16.41%, 169/1 030); the main fungi strains in child patients were C. albicans (52.50%, 63/120), C. parapsilosis (12.50%, 15/120) and C. tropicalis (9.17%, 11/120); the main fungi strains in adult patients were C. albicans (36.37%, 331/910), C. tropicalis (17.03%, 155/910) and C. parapsilosis (15.27%, 139/910). The isolation rate of main Candida strains from January to March and August to December was much higher than that of other months. The drug resistance rates of C. albicans to fluconazole and voriconazole were 7.14% and 7.43%, respectively, and the drug resistance rates to itraconazole were 50.44%. The resistance rates of C. tropicalis to fluconazole, voriconazole and itraconazole were 29.05%, 23.29% and 48.65%, respectively. The sensitivity rates of C. parapsilosi to fluconazole, voriconazole and itraconazole were 93.06%, 93.75% and 94.44%, respectively. Candida glabrata showed a dose-dependent sensitivity rate of 2.33% to fluconazole. Analysis of 244 blood fungi strains showed that non-candida albicans bacteremia accounted for 70.08%. In the pathogen spectrum covering 92.22%, fluconazole was sensitive to 64.65% of the pathogens, voriconazole was 68.88%, and amphotericin B was 88.75%. After quantification, the effective rates of fluconazole, voriconazole and amphotericin B in the clinical treatment of fungal bacteremia were 70.10%, 74.69% and 96.23%, respectively. Among them, the sensitivity rate of voriconazole to C. tropicalis was lower than that of fluconazole. Conclusions:Candida is the main clinical fungus isolates in hospitals of Shandong province. The resistance rate of C. tropicalis to azole antifungal drugs is on the rise, and the sensitivity of other Candida species to clinically used antifungal drugs is basically stable.
ABSTRACT
Objective:To discuss how to avoid the occurrence of adverse events and provides basis for improving the extracorporeal membrane oxygenation (ECMO) transport safety management to formulate the corresponding preventive measures through analyzing the causes and characteristics of adverse events in transport of ECMO.Methods:By using a self-designed ECMO transport observation table to collect data, with a retrospective study of adverse events in patients with ECMO transport in ECMO center of Beijing Chaoyang Hospital from January 2013 to June 2017, carrying out classification and analysis according to the causes of adverse events and the potential risks of the patients, thus put forward the feasible preventive measures.Results:There were 53 cases of ECMO transport in study period, with 18 cases (33.96%) of adverse events, among which the incidence of adverse events in inner-hospital transport was 34.21% (13/38) and that in inter-hospital transport was 33.33% (5/15). There was no patient died in ECMO transport. In the adverse events of ECMO transport, the main causes were related to transport staff, transport equipment and patient, which accounting for 1/3 of each. Among them, the most prominent was 4 cases (22.22%) of equipment lacking and 3 cases of battery and power supply (16.67%). In classification according to the risk degree of patients, 6 cases (33.33%) of third grade risk were found.Conclusions:It is safe and feasible to carry out ECMO transport in inner-hospital transport and inter-hospital transport based on ECMO transport team and transport process of this hospital. However the unexpected events of high risk or crisis of life is inevitable in ECMO transport. Through standardized training for ECMO team, with full assessment before transport, by the use of ECMO checklist and strict implementation of various transport processes and specifications, the incidence of adverse events in ECMO transport may be reduced.

OBJECTIVE：To rapidly evaluate the effectiveness ，safety and economics of Ginkgo biloba extract（EGb）in the treatment of Alzheimer ’s disease （AD）patients，and to provide evidence-based reference for clinical drug selection and decision. METHODS：Retrieved from PubMed ，Embase，Cochrane Library ，Web of Science ，CNKI，CBM，Wanfang database ，health technology assessment （HTA）organization websites and database during the inception to Aug. 10，2020，HTA reports ，systematic reviews/Meta-analysis，and pharmacoeconomic studies of EGb versus placebo in the treatment of AD were collected. After literature screening and data extration ，HTA checklist ，AMSTAR-2 scale and CHEERS scale were used respectively to evaluate the literature quality of the included HTA report ，systematic review/Meta-analysis and pharmacoeconomics studies. The conclusion of the included studies were summarized by using qualitative description. RESULTS ：A total of 9 literatures were included ，involving 8 systematic reviews and 1 economic studies. In terms of effectiveness ，there was no statistical significance in MMSE score of EGb group，ADAS-Cog score of 120 mg EGb group ，compared with placebo group （P＞0.05）. Dementia Quality of Life （DQoL）score of EGb group was significantly higher than that of placebo group. The scores of short cognitive aptitude tests ，neuropsychiatric inventory（NPI），NPI caregiver version score ，ADAS-Cog score of 160 mg EGb group and 240 mg EGb group were significantly lower than those of control group （P＜0.05）. ADL scores of patients were inconsistent ；ADL scores of EGb group were significantly lower than those o f placebo group （P＜0.05），or there was no significant diff erence between 2 groups（P＞0.05）； . subgroup analysis by dose showed that there was no RDY2019-39） significant difference in ADL score between 120 mg EGb group and placebo group （P＞0.05）；ADL score of 240 mg E-mail：renxiaolei83@126.com EGb group were signicantly lower than that of placebo group （P＜0.05）. Subgroup analysis of clinical global impression 010-88325751。E-mail：lyi1267@126.com change （CGIC） score showed that there was no significant difference in CGIC score between EGb group and placebo group after receiving ＜200 mg EGb and 26 weeks of treatment （P＞ 0.05）；CGIC score of EGb group was significantly higher than that of placebo group after receiving ＞200 mg EGb and 24 weeks of treatment （P＜0.05）. In terms of safety ，there was no statistical significance in the incidence of ADR or the incidence of severe ADR between EGb group and placebo group （P＞0.05）. Subgroup analysis by dose showed that the incidence of ADR in 240 mg EGb group was significantly higher than placebo group （P＜0.05）. Economically ，EGb treatment for AD is cost-effective ，which could indirectly save the nursing costs of AD patients. CONCLUSIONS ：The efficacy of EGb in the treatment of AD is uncertain ， and the safety and economy are good.
ABSTRACT
Objective:To construct Z-score ranges for normal fetal middle cerebral artery peak systolic velocity(MCA-PSV).Methods:From May 2017 to October 2019, 865 normal singleton fetuses of 10th to 40th gestational weeks underwent prenatal ultrasound in the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region. Using fetal biometric parameters as independent variables, and measurement of MCA-PSV on standard section as dependent variables, the regression analyses of the mean(M) and the standard deviation(SD) for each parameter were calculated separately and then the best fitting equation was selected. A group of diseases which might cause the abnormal MCA-PSV were assessed using these standards.Results:①Strong correlations were found between MCA-PSV and fetal biometric parameters ( r=0.935-0.939, P<0.001). ②Quadratic or cubic regression equations were fitted to the models of the means of the MCA-PSV, whereas linear equations were fitted to the SDs. ③In these case groups, intrauterine growth restriction, severe preeclampsia, intrauterine infection and homozygous α-thalassemia-1 demonstrated Z-score>2 reflective of increased MCA-PSV with varying degrees, especially with the homozygous α-thalassemia-1 fetus being the most significant (17/20, 85%). Conclusions:The calculation of Z-score for MCA-PSV as a function of fetal biometric parameters is intuitive and simple, it can be used as an important indicator especially for homozygous α-thalassemia-1.
ABSTRACT
Objective:To observe the effect of different asparaginase on the incidence of drug-induced diabetes in children with acute lymphoblastic leukemia(ALL) during combined chemotherapy.Methods:A total of 100 ALL children hospitalized in Zhucheng People's Hospital from January 2016 to December 2018 were selected in this study.According to the difference of asparaginase, 67 cases were divided into L-asparaginase group, and 33 cases were divided into pegaspargase group.The demographic, clinical indicators and remission after chemotherapy were compared between the two groups, and logistic regression model was used to analyze the influencing factors of diabetes mellitus during treatment.Results:There were statistically significant differences in random blood glucose ( t=2.515, P=0.014), albumin ( t=2.407, P=0.018), serum C-peptide ( t=2.030, P=0.045) and diabetes mellitus ( t=5.380, P=0.002) between the two groups after chemotherapy ( P<0.05). During chemotherapy, drug-induced diabetes mellitus had the highest incidence in induction remission period.The incidence of the L-asparaginase group (31.3%, 21/67) was higher than that of the pegaspargase group (12.1%, 4/33) (χ 2=4.357, P=0.037). Age (χ 2=7.748, P=0.005), risk stratification (χ 2=10.500, P=0.005) and types of chemotherapeutic drugs (χ 2=7.752, P=0.005) were independent influencing factors for the occurrence of drug-induced diabetes in children with ALL during chemotherapy ( P<0.05). The older the age, the greater the risk of diabetes mellitus during chemotherapy.The risk of drug-induced diabetes mellitus in pegaspargase group was 0.107 times higher than that in L-asparaginase group.The risk of drug-induced diabetes in high-risk children was 9.916 times higher than that in low-risk children. Conclusion:Drug-induced diabetes mellitus in ALL children treated with asparaginase combined with chemotherapy mainly occurs in the early stage of chemotherapy.The risk of drug-induced diabetes mellitus in ALL children treated with L-asparaginase combined with chemotherapy is higher than that of pegaspargase.Pegaspargase combined with chemotherapy in the treatment of ALL children can effectively reduce the incidence of drug-induced diabetes during chemotherapy.
ABSTRACT
To investigate psychological characteristics in different clinical subgroups of insomniacs, and to provide the basis for the accurate simplification of cognitive behavioral therapy for insomnia. Methods: A total of 212 insomniacs from November 2014 to June 2017 in Clinical Psychology Department or Sleep Department of 2 general hospitals in Hunan Province were included in convenient and classified into sleep onset insomnia (SOI), difficulty maintaining insomnia (DMI), early morning awakening insomnia (EMAI), and combined insomnia (CI) subgroups. Ford Insomnia Response to Stress Test (FIRST), Simplified Coping Style Questionnaire (SCSQ), Dysfunctional Beliefs and Attitudes about Sleep Scale 16 version (DBAS-16), Sleep-Related Behavior Questionnaire (SRBQ), Pre-sleep Arousal Scale (PSAS), Center for Epidemiological Studies Depression Scale (CES-D), Beck Anxiety Inventory (BAI) were used to investigate the psychological characteristics. Results: SOI and CI insomniacs had a higher frequency in use of sleep-related behavior than those with DMI; CI had a higher frequency in use of sleep-related behavior than those with EMAI (all P<0.05). Both SOI and CI insomniacs had a higher level of pre-sleep cognitive arousal than DMI and EMAI (all P<0.05). CI insomniacs noticed more consequences of insomnia and had more worries on insomnia than DMI, and CI insomniacs had more expectations of sleep than SOI (all P<0.05). Conclusion: Insomniacs with different clinical subgroups have different features of psychological characteristics. Both the insomnia subgroups and the psychological characteristics should be taken into account when we simplify cognitive behavioral therapy for insomnia (CBT-I) precisely.
