Objective This study aims to investigate the effect of rehabilitation skills training on suicide and relapse prevention of patients with depression.Methods Eighty patients were randomly divided into two groups.One group accepted depression rehabilitation skills training and the other group accepted general health education for 4 weeks.Both groups were followed up by 12 months,and the number of relapse and suicide and the score of Health-related quality of life made by Word Health Organization (WHOQOL-BREF) were recorded.Results The rate of relapse (10.0％ vs.42.5％) and hospitalization (5.0％ vs.20.0％) were lower in skills training group than in control group (P＜0.05).Rate of seeking help of suicide was higher in skills training group than in control group (25.5％ vs.7.5％) (P＜0.05).The suicide mortality was insignificantly different between two groups (0.0％ vs.2.5％) (P＞0.05).The scores of WHOQOL-BREF were significantly higher in skills training group than in control group in follow-up (P＜0.05).Conclusions Rehabilitation skills training program can not only reduce the rate of relapse and suicide but also improve the quality of life of patients with depression.

Objective:To investigate the distribution characteristics of virulence-related phenotypes/genotype, capsular serotype, drug resistance phenotypes, and sequence typing (ST) of Klebsiella pneumoniae in patients living in Zhongjiang county, improve clinical understanding, and provide evidence for the prevention and control of bacterial drug resistance and clinical rational drug use. Methods:The data of 135 strains of Klebsiella pneumoniae isolated from patients who received treatment in Zhongjiang County People's Hospital from July to December 2019 were retrospectively analyzed. Bacterial identification and drug sensitivity testing were performed using the WalkAway-40Plus automated microbiology system. Strains with a high viscosity phenotype were identified using wire drawing experiments. Hypervirulence-associated capsular serotype and virulence genes were verified by polymerase chain reaction. ST of Klebsiella pneumoniae strain was identified using multilocus sequence typing. Results:Strains with a high viscosity phenotype were identified in 50.4% of the 135 strains. 54.1%, 54.8%, and 54.1% of the strains were positive for virulence genes iucA, iroN, rmpA. The proportion of strains with capsular Serotype K1 or K2 was 11.9% and 15.6%, respectively. A total of 65 kinds of ST were identified, with ST23 and ST37 being the most common, accounting for 11.1% and 6.7%, respectively. The resistance rate of the strains to 16 kinds of antibiotics was 0.0%-25.2%, and the resistance rate to Carbapenem antibiotics, Amikacin, and Tigecycline was less than 1%. The positive rate of virulence gene of strains with a high viscosity phenotype was significantly higher than that of strains without a high viscosity phenotype ( P < 0.001), and its resistance rate to Cephalosporin was significantly lower in strains with a high viscosity phenotype than that in strains without a high viscosity phenotype ( P < 0.001). Conclusion:Klebsiella pneumoniae in Zhongjiang County is characterized by "high virulence and low drug resistance". It is necessary to continuously monitor the changes in the virulence and drug resistance of Klebsiella pneumoniae in Zhongjiang County, Sichuan Province, and be alert to the rapid dissemination of highly virulent strains.

Objective: To explore the effects of Buyang Huanwu decoction (BYHWD) on vascular neogenesis and hemorheological parameters following cervical spinal cord injury (SCI). Methods: An acute cervical SCI model was established using 84 female Sprague–Dawley rats. Functional recovery of the rats was evaluated using the forelimb locomotor scale score, forelimb grip strength test, and Basso-Beattie-Bresnahan score. The animals were subsequently euthanized at days 7 and 28 postoperatively. The gross morphology, neuronal survival, and myelin sheath in the injured area were evaluated using hematoxylin and eosin (HE), Nissl, and luxol fast blue (LFB) staining, respectively. Immunofluorescence staining was used to observe CD31 expression 7 days post-injury. Furthermore, the expression of CD31, neuronal nuclear protein (NeuN), and myelin basic protein (MBP) were evaluated 28 days post-injury. Additionally, vascular endothelial growth factor A (VEGFA) and VEGF receptor-2 (VEGFR-2) expression was evaluated using western blotting. Whole-blood viscosity, plasma viscosity, and red blood cell aggregation were measured using a hemorheometer. Results: From postoperative days 3–28, motor function in the BYHWD group began to recover considerably compared to the SCI group. BYHWD effectively restored spinal cord histopathology. In addition, the number of NeuN-positive cells, and fluorescence intensity of CD31at 7 and 28 days and MBP significantly increased in the BYHWD group compared with the SCI group (all P < .05). Moreover, this decoction significantly upregulated the expression of VEGFA and VEGFR-2 (all P < .05). BYHWD improved the hemorheology results (i.e., except erythrocyte aggregation index in the low-dose group), revealing statistically significant differences compared with the SCI group (all P < .05). Conclusion BYHWD effectively promoted angiogenesis, improved hemorheological parameters, and protected neurons and myelin sheaths, ultimately promoting the recovery of neurological function after cervical SCI in rats. These findings suggest that BYHWD promotes vascular neogenesis through the VEGFA/VEGFR-2 pathway.

Objective To establish the reference interval of serum non-high-density lipoprotein cholesterol(n-HDL-C)in adults in Yan'an city of Shaanxi Province and analyze the influencing factors.Methods A total of 16 921 adults from 10 towns in Yan'an City of Shaanxi Province from January to September 2023 were selected by random sampling.Age,sex,smoking,drinking,exercise,hypertension,diabetes,dyslipidemia,chronic disease,residence,eating habits,marital status,education and monthly income were investigated.Height,weight,waist circumference and blood pressure were measured.Serum triglyceride(TG),total cholesterol(TCHO),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),Apolipoprotein A1(ApoA1),Apolipoprotein B(ApoB)and lipoprotein a[Lp(a)]levels were detected,and n-HDL-C levels were calculated:n-HDL-C(mmol/L)=TCHO(mmol/L)-HDL-C(mmol/L).The 95％reference interval(P25～P97 5)was calculated according to the percentile method recommended in WS/T402-2012 Health Industry Standard of the People's Republic of China.Multivariate logistic regression was used to analyze the influencing factors of serum n-HDL-C level.Results The serum n-HDL-C levels in both males and females were not normally distributed(S=2.119,2.091,all P＜0.001).There were significant differences in serum levels of n-HDL-C among males aged＞60 years old[2.98(2.50,3.37)mmol/L],18～30 years old[2.84(2.49,3.26)mmol/L],31～40 years old[2.98(2.62,3.42)mmol/L],41～50 years old[3.10(2.62,3.47)mmol/L]and 51～60 years old[3.05(2.64,3.46)mmol/L]contrast,and the differences were significant(H=3.618～5.680,all P＜0.05).There were significant differences in serum levels of n-HDL-C among women aged 51～60 years[3.08(2.71,3.44)mmol/L],18～30 years[2.64(2.29,3.07)mmol/L],31～40 years[2.67(2.31,3.08)mmol/L]and 41～50 years old[2.94(2.58,3.29)mmol/L]contrast(H=8.161～13.445,all P＜0.001).There were significant differences in serum n-HDL-C levels among patients aged＞60 years old[2.98(2.57,3.34)mmol/L],18～30 years old,31～40 years old and 41～50 years old contrast,and the differences were significant(H=7.985～14.018,all P＜0.001).The reference interval of serum n-HDL-C level in adult population was obtained by combining the age groups with no statistical significance:males aged 18～60 years old(1.97～3.97mmol/L),＞60 years old(1.86～3.91mmol/L);females aged 18～50 years(1.82～3.74 mmol/L),＞50 years old(1.94～3.88 mmol/L).A total of 16 921 adults were divided into normal n-HDL-C group and abnormal group,and the differences of serum TG(1.02±0.31 mmol/L vs 1.24±0.37mmol/L),TCHO(3.97±1.02 mmol/L vs 4.66±1.25 mmol/L),LDL-C(2.37±0.58mmol/L vs 2.59±0.67 mmol/L)levels and age(43.55±11.52 years vs 46.27±8.13 years)between the two groups were significant(t=2.041～3.151,all P＜0.05),in which the abnormal rate of serum n-HDL-C level was 42.50％.Multivariate Logistic regression analysis showed that males,lack of exercise,overweight or obesity,dyslipidemia,urban residents,and high school education or above were the influential factors for serum n-HDL-C levels in adults in this region(all P＜0.05).Conclusion The reference interval of serum n-HDL-C level in adults in this area was preliminarily established.Males,lack of exercise,overweight or obesity,dyslipidemia,urban residents,and high school education or above were the influential factors of abnormal serum n-HDL-C levels in adults in this area.

Objective:To deeply analyze differences in characteristics of neurosyphilis between male and female patients with neurosyphilis, as well as between patients with symptomatic neurosyphilis and those with asymptomatic neurosyphilis, and to provide reference for the prevention and control, clinical diagnosis and treatment of neurosyphilis.Methods:A total of 131 inpatients with neurosyphilis were collected from Department of Dermatology and Venereology, the First Affiliated Hospital of Anhui Medical University from June 2015 to December 2019, and their clinical manifestations and laboratory findings were retrospectively analyzed. These patients were grouped according to gender and neurological/psychiatric symptoms. Measurement data were compared by using two-independent-sample t test or Mann-Whitney U test, and enumeration data were compared by using chi-square test and Fisher′s exact test, to analyze differences in clinical characteristics and laboratory indicators between different groups. Results:Among the 131 patients, there were 72 with asymptomatic neurosyphilis (asymptomatic group) and 59 with symptomatic neurosyphilis (symptomatic group). The proportion of patients receiving syphilis treatment was significantly lower in the symptomatic group (10.17%) than in the asymptomatic group (98.61%, OR = 0.002, P < 0.001). The misdiagnosis rate at the first clinical visit was significantly higher in the male patients (50.00%) than in the female patients (24.49%, OR = 3.08, P = 0.004), as well as in the symptomatic patients (89.83%) than in the asymptomatic patients (0, OR = 13.00, P < 0.001). The proportion of symptomatic patients was significantly higher in male patients (57.32%) than in female patients (14.64%, OR = 4.14, P = 0.003). Compared with the female patients, the male patients showed significantly increased positive rates of toluidine red unheated serum test (TRUST) in the cerebrospinal fluid samples (52.44% vs. 26.54%, OR = 3.05, P = 0.004), increased proportions of patients with elevated levels of total protein (> 0.5 g/L) in cerebrospinal fluids (79.27% vs. 59.18%, OR = 2.64, P = 0.01), increased total protein levels in cerebrospinal fluids (0.76 ± 0.41 g/L vs. 0.56 ± 0.25 g/L, P = 0.002), and increased detection rates of brain magnetic resonance imaging abnormalities (72.22% vs. 44.90%, OR = 2.13, P = 0.039). The age at diagnosis of the symptomatic female patients (50.82 ± 9.31 years) was significantly higher than that of the asymptomatic female patients (42.30 ± 12.18 years, P = 0.038). The positive rate of TRUST in the cerebrospinal fluid samples was significantly higher in the patients with symptomatic neurosyphilis (55.93%) than in those with asymptomatic neurosyphilis (31.94%, OR = 2.70, P = 0.006), and so was the total protein level in cerebrospinal fluids (0.79 ± 0.46 g/L vs. 0.60 ± 0.24 g/L, P = 0.003) . Conclusion:The misdiagnosis rate of neurosyphilis is high at the first clinic visit; the condition of male patients is more serious than that of female patients; anti-syphilitic treatment history, gender and age may play some role in the development of neurosyphilis.

UNLABELLEDObjective To compare the impact of right ventricular apical (RVA) versus right ventricular outflow tract (RVOT) pacing on left ventricular systolic synchronization.

METHODSSixty patients were prospectively recruited and randomized into RVA group (n=30) with the right ventricle leads placed in the RVA and RVOT group (n=30) with right ventricle leads placed in the septum of the RVOT. Speckle tracking imaging was performed with 100% ventricle pacing to measure the differences in the time to maximum left ventricle (LV) radial strain.

RESULTSIn RVA group, the difference in the time to 6-segment maximum LV radial strain after pacing was 105.27 ± 19.74 ms, significantly greater than that in RVOT group (41.65 ± 12.17 ms, P<0.001). The standard difference of time to 6-segment maximum LV radial strain was also significantly greater in RVA group than in RVOT group (42.71 ± 17.63 vs 17.63 ± 5.62 ms, P<0.001).

CONCLUSIONLeft ventricle systolic synchronizaition after RVOT pacing is superior to RVA pacing.

Objective:To understand the current situation of psychological crisis vulnerability among elderly individuals with multimorbidity and analyze the factors that influence it, to provide insights for improving their coping abilities.Methods:A cross-sectional survey design was conducted at Renmin Hospital of Wuhan University from May 1 to November 30, 2022.The attitudes toward aging, sense of meaning of life, and vulnerability to psychological crisis were analysed among outpatients and inpatients.Statistical analysis was performed on the questionnaire results, and the influencing factors of vulnerability to psychological crisis in elderly patients with co-morbidities were analyzed using one-way linear regression and multivariate linear regression.Additionally, the correlation between aging attitudes, sense of meaning of life, and vulnerability to psychological crisis was examined using Pearson correlation analysis.Results:A total of 685 questionnaires were distributed, and 602 valid questionnaires were collected, resulting in a valid recovery rate of 87.9%.The total score for the sense of meaning of life in elderly co-morbid patients was(39.2±8.3), while the total score for aging attitudes was(80.2±13.5).The total score for psychological crisis vulnerability was(69.4±12.8), indicating a medium-high level of vulnerability.The results of multiple linear regression analysis revealed that the factors influencing psychological crisis vulnerability in elderly multimorbidity, in descending order, were residence status, economic situation, marital status, age, type of chronic disease, and hospitalization history in the past six months.Psychological crisis vulnerability in elderly multimorbidity showed a negative correlation with the sense of meaning of life and the attitude of aging( r=-0.315, -0.264, both P<0.01), while the attitude of aging exhibited a positive correlation with the sense of meaning of life( r=0.515, P<0.01). Conclusions:The vulnerability of elderly individuals with multimorbidity to psychological crises is influenced by several factors.Healthcare professionals should prioritize individuals who are elderly, residing in nursing institutions, widowed, financially disadvantaged, experiencing multiple illnesses, and not currently hospitalized.

Objective:To explore the influence of blood pressure during peri-thrombolysis period (from admission to 24 h after thrombolysis) in intracranial hemorrhage, improvement of neurological function, primary endpoint event (recurrence of symptomatic stroke) and secondary endpoint events (complex cardiovascular and cerebrovascular events, and all-cause death) in patients with acute ischemic stroke.Methods:A total of 422 patients with acute ischemic stroke who underwent intravenous thrombolysis with alteplase during hospitalization at National Center for Stroke in Lianyungang from January 2015 to March 2019 were followed up for 90 d. According to the quintile of mean systolic and diastolic blood pressures during peri-thrombolysis period, they were divided into group of blood pressure <130.00 mmHg (Q1), group of blood pressure of 130.00-140.49 mmHg (Q2), group of blood pressure of 140.50-147.99 mmHg (Q3), group of blood pressure of 148.00-158.00 mmHg (Q4), and group of blood pressure >158.00 mmHg (Q5), and group of blood pressure <71.30 mmHg (G1), group of blood pressure of 71.30-76.19 mmHg (G2), group of blood pressure of 76.20-81.89 mmHg (G3), group of blood pressure of 81.90-90.79 mmHg (G4), group of blood pressure >90.79 mmHg (G5). Univariate and multivariate Logistic regression analyse were used to evaluate the relations of blood pressure with postoperative intracranial hemorrhage and neurological function improvement. Kaplan-Meier curve, Log-rank test and multivariate Cox proportional risk model were used to evaluate the relations of blood pressure with primary endpoint event and secondary endpoint events.Results:(1) After adjusting for confounding factors, multivariate Logistic regression analysis showed that the risk of postoperative intracranial hemorrhage in patients from Q2 was significantly lower than that in patients from Q5 ( OR= 0.160, 95%CI: 0.031-0.827, P=0.029). (2) After adjusting for confounding factors, multivariate Logistic regression analysis showed that the probability of postoperative improvement of nerve function in patients from Q2 and Q3 was significantly higher than that in patients from Q5 ( OR=2.144, 95%CI: 1.043-4.407, P=0.038; OR=2.224, 95%CI: 1.105-4.479, P=0.025); the probability of postoperative improvement of nerve function in patients from G3 and G4 was significantly higher than that in patients from G5 ( OR= 2.153, 95%CI: 1.081-4.287, P=0.029; OR=2.182, 95%CI: 1.131-4.210, P=0.020). (3) After adjusting for confounding factors, multivariate Cox proportional risk model showed that the risk of primary endpoint event in patients from Q1 and Q2 was significantly lower than that in patients from Q5 ( HR=0.079, 95%CI: 0.010-0.613, P=0.015; HR=0.211, 95%CI: 0.062-0.724, P=0.013). (4) After adjusting for confounding factors, multivariate Cox proportional risk model showed that the risk of secondary endpoint events in patients from Q1, Q2, Q3 and Q4 was significantly lower than that in patients from Q5 ( HR=0.246, 95%CI: 0.100-0.607, P=0.002; HR=0.360, 95%CI: 0.177-0.732, P=0.005; HR=0.448, 95%CI: 0.246-0.817, P=0.009; HR=0.467, 95%CI: 0.252-0.867, P=0.016). Conclusion:The risks of postoperative intracranial hemorrhage, primary endpoint event and secondary endpoint events in patients with acute ischemic stroke decrease with the decrease of systolic blood pressure during peri-thrombolysis period; moderate blood pressures (systolic blood pressure: 130.00-147.99 mmHg; diastolic blood pressure:76.20-90.79 mmHg) are beneficial for improvement of neurological function.
