AIM To investigate the effects of tectorigenin on preadipocyte differentiation and the possible mechanism.METHODS CCK8 method was used to detect the effects of tectorigenin on 3T3-L1 cell viability.After 2 days contact inhibition(Day 0 of differentiation),the cells were exposed to inducer and tectorigenin of different concentrations(0,10,20,40,60 μmol/L),in contrast to those of the control group with no inducer use.On the 9th day of differentiation,the cells had their lipid droplets observed by oil red O staining;their levels of TG and NEFA detected by biochemical kit;their protein expressions of PPARγ,C/EBPα,perilipin-1,ADFP,AMPKα and p-AMPKα detected by Western blot;and their mRNA expressions of Adiponectin,FABP4,FAS and Acly detected by RT-qPCR.RESULTS Tectorigenin concentration of 60 μmol/L or lower levels left no impact upon the cell viability(P＞0.05).Compared with the model group with induced differentiation,the groups intervened with tectorigenin administration displayed decreased formation of lipid droplets;lower levels of TG and NEFA(P＜0.01);decreased protein expressions of C/EBPα,PPAR γ,perilipin-1 and ADFP(P＜0.01);increased protein expressions of AMPKα and p-AMPKα(P＜0.01);and decreased mRNA expressions of Adiponectin,FABP4,FAS and Acly(P＜0.01).CONCLUSION Tectorigenin inhibits preadipocyte differentiation into mature adipocytes,which may be related to its efficacy in the regulation of C/EBPα,PPARγ,AMPKα and p-AMPKα.

Objective:To investigate the influence of liver drainage volume on overall survival time in patients with unresectable malignant hilar bile duct obstruction.Methods:Data of 633 patients with unresectable malignant hilar bile duct obstruction (BismuthⅡ-Ⅳ) who underwent endoscopic stent drainage in 3 endoscopy centers from January 2002 to May 2019 were retrospectively analyzed. Main observation indicators included clinical success rate, stent patency, overall survival, the effective liver drainage volume, and complication incidence.Results:The clinical success rates of patients with liver drainage volume <30%, 30%-50%, and >50% were 56.8% (25/44), 77.3% (201/260) and 84.2% (277/329) respectively. The incidences of early cholangitis were 31.8% (14/44), 18.8% (49/260) and 16.1% (53/329). The median stent patency time was 4.5 (95% CI: 1.8-7.2) months, 5.6 (95% CI: 5.0-6.2) months and 6.6 (95% CI: 5.2-8.0) months. The overall survival time was 2.4 (95% CI: 1.8-3.0) months, 4.0 (95% CI: 3.4-4.6) months and 4.9 (95% CI:4.4-5.4) months, respectively. The clinical success rate ( χ 2=8.28, P=0.012), median stent patency period ( χ 2=18.87, P=0.015) and overall survival time ( χ 2=6.93, P=0.024) of 30%-50% liver drainage volume group were significantly higher than those of <30% group. Further multivariate cox regression analysis showed that the disease type (hepatocellular carcinoma VS hilar cholangiocarcinoma: HR=1.50, 95% CI:1.18-1.91, P=0.001; gallbladder carcinoma VS hilar cholangiocarcinoma: HR=1.45, 95% CI:1.14-1.85, P=0.002; metastatic cholangiocarcinoma VS hilar cholangiocarcinoma: HR=1.48, 95% CI:1.08-2.04, P=0.015), bilirubin level >200 μmol/L ( HR=1.35, 95% CI:1.14-1.60, P<0.001),metal stents ( HR=0.67, 95% CI:0.56-0.79, P<0.001), liver drainage volume (volume 30%-50% VS <30%: HR=0.64, 95% CI: 0.45-0.90, P=0.010; volume>50% VS <30%: HR=0.58, 95% CI:0.41-0.81, P=0.002) and anti-tumor therapy ( HR=0.51, 95% CI:0.42-0.61, P<0.001) were independent predictors for overall survival time of patients with unresectable malignant hilar bile duct obstruction. Conclusion:When endoscopic stent drainage is performed for patients with unresectable malignant hilar bile duct obstruction, at least 30% liver volume is required for better overall survival. In addition, the use of metal stent drainage and anti-tumor therapy may increase survival benefits.

Objective: To investigate the impact of combined use and timing of arterial-venous extracorporeal membrane oxygenation (VA-ECMO) with intra-aortic balloon pump (IABP) on the prognosis of patients with acute myocardial infarction complicated with cardiogenic shock (AMICS). Methods: This was a prospective cohort study, patients with acute myocardial infarction and cardiogenic shock who received VA-ECMO support from the Heart Center of Lanzhou University First Hospital from March 2019 to March 2022 in the registration database of the Chinese Society for Extracorporeal Life Support were enrolled. According to combination with IABP and time point, patients were divided into VA-ECMO alone group, VA-ECMO+IABP concurrent group and VA-ECMO+IABP non-concurrent group. Data from 3 groups of patients were collected, including the demographic characteristics, risk factors, ECG and echocardiographic examination results, critical illness characteristics, coronary intervention results, VA-ECMO related parameters and complications were compared among the three groups. The primary clinical endpoint was all-cause death, and the safety indicators of mechanical circulatory support included a decrease in hemoglobin greater than 50 g/L, gastrointestinal bleeding, bacteremia, lower extremity ischemia, lower extremity thrombosis, acute kidney injury, pulmonary edema and stroke. Kaplan-Meier survival curves were used to analyze the survival outcomes of patients within 30 days of follow-up. Using VA-ECMO+IABP concurrent group as reference, multivariate Cox regression model was used to evaluate the effect of the combination of VA-ECMO+IABP at different time points on the prognosis of AMICS patients within 30 days. Results: The study included 68 AMICS patients who were supported by VA-ECMO, average age was (59.8±10.8) years, there were 12 female patients (17.6%), 19 cases were in VA-ECMO alone group, 34 cases in VA-ECMO+IABP concurrent group and 15 cases in VA-ECMO+IABP non-concurrent group. The success rate of ECMO weaning in the VA-ECMO+IABP concurrent group was significantly higher than that in the VA-ECMO alone group and the VA-ECMO+IABP non-concurrent group (all P<0.05). Compared with the ECMO+IABP non-concurrent group, the other two groups had shorter ECMO support time, lower rates of acute kidney injury complications (all P<0.05), and lower rates of pulmonary edema complications in the ECMO alone group (P<0.05). In-hospital survival rate was significantly higher in the VA-ECMO+IABP concurrent group (28 patients (82.4%)) than in the VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (7 patients) (all P<0.05). The survival rate up to 30 days of follow-up was also significantly higher surviving patients within were in the ECMO+IABP concurrent group (26 cases) than in VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (4 patients) (all P<0.05). Multivariate Cox regression analysis showed that compared with the concurrent use of VA-ECMO+IABP, the use of VA-ECMO alone and non-concurrent use of VA-ECMO+IABP were associated with increased 30-day mortality in AMICS patients (HR=2.801, P=0.036; HR=2.985, P=0.033, respectively). Conclusions: When VA-ECMO is indicated for AMICS patients, combined use with IABP at the same time can improve the ECMO weaning rate, in-hospital survival and survival at 30 days post discharge, and which does not increase additional complications.

Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.

Objective:To investigate the application value of different metal stents place-ment position in endoscopic drainage of malignant hilar bile duct obstruction.Methods:The retro-spective cohort study was conducted. The clinicopathological data of 300 patients with malignant hilar bile duct obstruction who were admitted to 3 medical centers, including 216 patients in the Third Affiliated Hospital of Naval Medical University, 48 patients in the Xijing Hospital of Air Force Medical University, 36 patients in the First People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine, from January 2012 to January 2019 were collected. There were 164 males and 136 females, aged (67±12)years. All patients were determined to be unresectable by multidisciplinary consultation and underwent endoscopic retrograde cholangiopancreatography. Observation indicators: (1) clinicopathological features of patients; (2) follow-up; (3) analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Follow-up was conducted using outpatient examination and telephone interview to detect patency of metal biliary stents and survival of patients up to July 2019 or death of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used to conduct survival analysis. COX regression model was used for univariate and multivariate analyses. Factors with P<0.1 in univariate analysis were included in multivariate analysis. Results:(1) Clinicopathological features of patients. Of the 300 patients, 163 cases underwent endoscopic drainage with at least one metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as crossing papilla), and 137 cases underwent endoscopic drainage with no metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as no crossing papilla). Age, disease type (hilar cholangiocarcinoma, hepatocellular carcinoma, intrahepatic cholangio-carcinoma, gallbladder carcinoma, metastatic cholangiocarcinoma), metal biliary stents type (unilateral metal biliary stent, bilateral metal biliary stents) of patients with crossing papilla were (68±13)years, 95, 8, 11, 31, 18, 63, 100, respectively. The above indicators of patients with no crossing papilla were (64±12)years, 63, 22, 20, 23, 9, 126, 11, respectively. There were significant differences in the above indicators between patients with crossing papilla and patients with no crossing papilla ( t=2.70, χ2=17.69, 90.79, P<0.05). (2) Follow-up. All the 300 patients were followed up for 5.4(3.1,9.3)months. The patency time of metal biliary stents was 9.0(8.2,9.8)months and 6.4(4.8,8.0)months of patients with crossing papilla and patients with no crossing papilla, showing a significant difference between them ( χ2=8.23, P<0.05). The overall survival time was 5.5(4.2,6.8)months and 5.5(4.3,6.8)months of patients with crossing papilla and patients with no crossing papilla, showing no significant difference between them ( χ2=0.28, P>0.05). (3) Analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Results of univariate analysis showed that type of metal biliary stents and the placement position of metal biliary stents were related factors affecting the patency time of metal biliary stents [ hazard ratio( HR)=0.44, 0.60, 95% confidence intervals as 0.30?0.64, 0.42?0.85, P<0.05]. Results of multi-variate analysis showed that bilateral metal biliary stents was an independent protective factor for the patency time of metal biliary stents ( HR=0.46, 95% confidence interval as 0.29?0.72, P<0.05). Results of univariate analysis showed that disease type (intrahepatic cholangiocarcinoma versus hilar cholangiocarcinoma), preoperative serum total bilirubin, type of metal biliary stents, anti-tumor therapy were related factors affecting the overall survival time of patients ( HR=1.05, 1.43, 0.72, 0.61, 95% confidence intervals as 0.70?1.57, 1.12?1.83, 0.55?0.92, 0.47?0.81, P<0.05). Results of multi-variate analysis showed that age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L were independent risk factors for the overall survival time of patients ( HR=1.35, 1.98, 1.46, 95% confidence intervals as 1.02?1.79, 1.40?2.80, 1.13?1.89, P<0.05), and bilateral metal biliary stents, anti-tumor therapy were independent protective factors for the overall survival time of patients ( HR=0.68, 0.60, 95% confidence intervals as 0.53?0.89, 0.45?0.80, P<0.05). Conclusions:Endoscopic drainage with or without metal biliary stents' distal portion crossing the duodenal main papilla is safe and feasible for patients with malignant hilar bile duct obstruction. Bilateral metal biliary stents is an independent protective factor for the patency time of metal biliary stents. Age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L are independent risk factors for the overall survival time of patients, and bilateral metal biliary stents, anti-tumor therapy are independent protective factors for the overall survival time of patients.

OBJECTIVE: To detect variants of IVD gene among 4 neonates with suspected isovalerate acidemia in order to provide a guidance for clinical treatment. METHODS: 111 986 newborns and 7461 hospitalized children with suspected metabolic disorders were screened for acyl carnitine by tandem mass spectrometry. Those showing a significant increase in serum isovaleryl carnitine (C5) were analyzed for urinary organic acid and variants of the IVD gene. RESULTS: Four cases of isovalerate acidemia were detected, which included 2 asymptomatic newborns (0.018‰, 2/111 986) and 2 children suspected for metabolic genetic diseases (0.268‰, 2/7461). The formers had no obvious clinical symptoms. Analysis of acyl carnitine has suggested a significant increase in C5, and urinary organic acid analysis has shown an increase in isovaleryl glycine and 3-hydroxyisovalerate. Laboratory tests of the two hospitalized children revealed high blood ammonia, hyperglycemia, decreased red blood cells, white blood cells, platelets and metabolic acidosis. The main clinical manifestations have included sweaty foot-like odor, feeding difficulty, confusion, drowsiness, and coma. Eight variants (5 types) were detected, which included c.158G>A (p.Arg53His), c.214G>A (p.Asp72Asn), c.548C>T (p.Ala183Val), c.757A>G (p.Thr253Ala) and 1208A>G (p.Tyr403Cys). Among these, c.548C>T and c.757A>G were unreported previously. None of the variants was detected by next generation sequencing of 2095 healthy newborns, and all variants were predicted to be likely pathogenic based on the guidelines from the American College of Medical Genetics and Genomics. CONCLUSION The incidence of isovalerate acidemia in Liuzhou area is quite high. Screening of metabolic genetic diseases is therefore recommended for newborns with abnormal metabolism. The discovery of novel variants has enriched the mutational spectrum of the IVD gene.

Objective: To analyze the association of personality characteristics and cognitive adjustment strategies among parents of adolescents with non suicidal self injury(NSSI) with adolescent NSSI. Methods: Adolescents with NSSI who visited the hospital from January 2020 to January 2021 were recruited as the case group( n =60), and healthy adolescents recruited in the school, community and hospital were selected as the control group( n =60). The participants parents completed the Chinese Big Five Personality Inventory and the Chinese version of the Cognitive Emotion Regulation Questionnaire (CERQ-C), Logistic regression was used to explore the associations. Results: Parents of the control group had higher scores of openness (40.90±6.19) and conscientiousness (48.18±6.12) than parents of the case group (36.88±5.02)(44.12±6.58) ( t =3.90，3.50， P <0.05). In terms of negative events, scores of acceptance, positive reappraisal, refocusing on planning, positive refocusing and putting into perspective were higher among parents of the control group than among parents of the case group ( t =3.43，3.58，2.36，5.44，3.53， P <0.05). Among parents of the case group, neuroticism was positively correlated with putting into perspective ( r =0.31) and catastrophizing ( r =0.37). Openness was positively correlated with positive refocusing ( r =0.30) and positive reappraisal ( r =0.27). Acceptance was negatively correlated with extroversion ( r = -0.29 ), openness ( r =-0.40), conscientiousness ( r =-0.26),while other blame was negatively correlated with extroversion ( r = -0.35 ), agreeableness ( r =-0.36). Extraversion was negatively associated with positive refocusing ( r =-0.32)( P <0.05). According to binary regression analysis, the income of parents in the case group ( OR =0.49), education ( OR =0.60), acceptance ( OR =0.59), positive reappraisal ( OR =0.45), putting into perspective ( OR =0.53), neuroticisms ( OR =0.81), openness ( OR =0.76) and conscientiousness ( OR =0.74) were risk factors, whereas refocusing on planning ( OR =2.09) and self blame ( OR =1.55) were protective factors of NSSI in the case group( P <0.05). Conclusion When confronted with adverse events, the personality characteristics of parents of children with NSSI, and the emotional regulation strategies adopted by these parents, have influence on the prevalence of NSSI in this population.

Objective To explore the incidence rate of mild cognitive impairment (MCI) among the elderly which transferred to Alzheimer disease (AD) and to analyze the related influencing factors. Methods 10 urban communities were selected through stratified cluster sampling as the research sites where 361 patients with MCI were screened from 1 942 residents aged over 60 years old. Questionnaires and laboratory assays were used to collect data from subjects, including characteristics of demographic, life style, medical history, Alzheimer-associated neuronal thread protein,(AD7C-(NTP)), amyloid β-protein 42(Aβ42) and amyloid β-protein 40(Aβ40), etc. Patients with MCI were followed up for three years to determine whether they progressed to AD. Results 121 of 361 patients of MCI converted to AD, and the incidence rate of MCI to AD was 9.49% person-years. According to the results of Logistic regression analysis model, elder (80-89 years) (OR=3.651,95% CI:1.295-10.297, P<0.001),female (OR=2.603,95% CI:1.136-5.966, P<0.001), heavy drinking(OR=1.479,95% CI:1.343-1.627, P<0.001), increased ADL score (OR=1.790, 95% CI:1.443-2.220, P=0.031) and smoking (OR=1.157,95% CI:1.091-1.224, P<0.001) were the risky factors of the transition of MCI to AD. The increase of Moca score (OR=0.766,95% CI:0.681-0.861, P<0.001) was the protective factor of the transition. Conclusions We should strengthen our monitor on elder female MCI patients, and promote healthy lifestyles among the elders, encouraging them to actively participate in physical exercises and reading, in order to delay patients' transition of MCI to AD.
