Objective To describe depression in liver transplant(LT)recipients and explore their coping styles.Methods One hundred transplant recipients were divided into three groups according to the time after LT:one to six months after the operation(group1),six months to one year(group2)and one to three years after the operation(group3).A self-rating depression scale(SDS)was used to measure their depression levels,and a Medical Coping Modes questionnaire(MCMQ)Was used to investigate their coping styles.The results were compared with those from a general population,and the relevance of depression symptoms and coping styles was analysed. Results The average SDS score of all the LT recipients was 41.03±7.14(42.90±7.18 for group 1.40.71±7.97 for group 2 and 39.69±6.00 for group 3).The average depression scores of the three groups were all significantly higher than in the normal population,but there was no statistically significant difference among the three groups.The depression scores were negatively correlated with the confrontation aspect of coping style,while positively correlated with avoidance and resignation.Conclusion LT recipients tend to be depressed,and the level of depression is strongly related with their coping styles.

Objective To assess the left ventricular(LV)segmental function by velocity vector imaging(VVI)in uremic patients with diffferent quantity of parathyroid hormone(PTH).Methods Sixty patients with uremia were divided into 2 groups according to the value of PTH:group A with PTH less than 3 times of upper normal limit,group B with PTH more than 3 times of upper normal limit.Normal control group was 30 healthy subj ects.All people were evaluated by VVI.The parameters,including the longitudinal systolic strain rate(SSR),diastolic strain rate(DSR),were analysed among the three groups.Results Compared with normal group,in group A and B,SSR,DSR in all segments were lower.Compared with group A,in group B,DSR were all significantly lower(P＜0.05),SSR in apex of laternal wall,medium of anterior septum wall,posterior wall,medium and apex of posterior septum wall and superior wall,base,medium and apex of anterior wall were significantly lower(P＜0.05).There was no statistically significant difference of left ventricular ejection fraction between the two groups(P＞0.05).Conclusions VVI is a viable objective tool to quantitatively assess LV segmental function damaged by different quantity of PTH.

AIM: To study the effect of ERK inhibition on the mitochondrial potential change in dexamethasone (DEX)-induced thymocyte apoptosis. METHODS: ERK activity was inhibited by PD098059 (PD), and 4 experimental groups were set: control, PD only, DEX and PD+DEX. Annexin V-FITC/PI double staining flowcytometry was used to detect apoptotic cells at time points of 3 h, 5 h and 7 h. JC-1 staining flowcytometry was adopted to examine mitochondrial membrane potential (△?m) at time points of 3 h, 7 h and 11 h. RESULTS: By stimulation with 1 ?mol/L DEX, the apoptotic rates of mouse thymocytes at 3 h, 5 h and 7 h were (19.63?0.35)%, (41.84?1.67)% and (67.00?2.43)%, respectively, and had significantly difference from control group (4.98?0.39)%, (6.08?0.33)% and (9.31?0.34)% (P0.05). At 3 h, 7 h and 11 h, the rates of low △?m cells were (21.23?1.43)%, (55.34?1.78)% and (70.88?2.87)%, significantly higher than that in control group (P0.05). CONCLUSION: DEX induces mouse thymocyte apoptosis at least partly through ERK pathway, and ERK inhibition has an important biological significance during this process.

Objective:To understand the current status and analyze the factors of demoralization of patients with chronic heart failure (CHF), providing references for targeted psychological interventions of nursing staff.Methods:Using the cross-sectional survey method, from August 2022 to January 2023, 282 CHF patients who were followed up in the Cardiovascular Department of the First Affiliated Hospital of Zhengzhou University were selected as the study subjects. They were investigated using the General Information Questionnaire, Demoralization Scale Revised Mandarin Version, Brief Illness Perception Questionnaire (BIPQ), Fear of Progression Questionnaire-Short Form (FoP-Q-SF), and the factors influencing the demoralization of CHF patients were analyzed using univariate analysis and multiple linear regression.Results:Among 282 cases, male 172 cases, female 110 cases, aged (62.29±10.05) years old. The Demoralization Scale Revised Mandarin Version′s score of CHF patients was (30.30 ± 10.37) points; the score of BIPQ was (42.18 ± 13.94) points; the score of FoP-Q-SF was (35.41 ± 7.29)points, which were at high level. The results of multiple linear regression analysis showed that patient disease duration, disease stages, New York heart association cardiac function classification, the score of BIPQ, and the score of FoP-Q-SF were factors influencing the demoralization of CHF patients ( t values were 3.08 to 12.50, all P<0.05). Conclusions:There is an urgent need to focus on the current status of the demoralization of CHF patients. It is necessary to develop a systematic and effective intervention strategy for demoralization, to take into account patient disease duration, disease stages, illness perception, and fear of progression in a comprehensive manner.

OBJECTIVETo analyze (CGG)n repeats sequence and AGG interspersion correlated with unstable expansion of FMR1 gene in a general Chinese population.

METHODSAmplideX FMR1 PCR Kit was used to amplify 380 X chromosomes from randomly selected 176 males and 102 females, 11 permutation carriers and 10 full mutation patients have served as controls. Results of capillary electrophoresis were analyzed with GeneMapper software Version 4.0. SPSS 11.0 software was used for statistical analysis.

RESULTSThe ratio of heterozygous females was 64.70%. The number of alleles in general males and females was 15 and 14, the classes of AGG pattern was 26 and 27, respectively. The range of alleles was between 17 to 45 CGG repeats in males and 21 to 44 CGG repeats in females, and 1 male was identified as gray zone carrier. The most frequent allele was 29 CGG repeats, which was followed by 30 and 36 repeats, while 28 CGG repeats were absent. The most common AGG pattern was 9A9A9, 99.21% of the population was detected with different forms and numbers of AGG interruption, and 6A interruption pattern was found in 10.02% samples especially in individuals with more CGG repeats. However, 57.58% of control samples had no AGG interruption, and none of the controls had 6A interruption pattern. No significant difference was observed in allele frequent distribution of (CGG)n repeats and AGG interspersion patterns between the males and females (P > 0.05), and AGGs was significantly different between general population and controls (P < 0.05).

CONCLUSIONAGGs and AGG pattern may have important roles in maintaining (CGG)n stability in general population of China, 9A9A6A9 may be a special pattern for preventing (CGG)n unstable expansion in Asian populations.

OBJECTIVE: To explore the pathogenesis of two fetuses from one family affected with Joubert syndrome (JS). METHODS: Whole exome sequencing was employed to screen potential mutations in both fetuses. Suspected mutations were verified by Sanger sequencing. Impact of intronic mutations on DNA transcription was validated by cDNA analysis. RESULTS: Two novel TCTN1 mutations, c.342-8A>G and c.1494+1G>A, were identified in exons 2 and 12, respectively.cDNA analysis confirmed the pathogenic nature of both mutations with interference of normal splicing resulting in production of truncated proteins. CONCLUSION The genetic etiology of the family affected with JS has been identified.Above findings have enriched the mutation spectrum of TCTN1gene and facilitated understanding of the genotype-phenotype correlation of JS.

Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Objective:To investigate the effect of 131I therapy on the clinical outcome of patients with differentiated thyroid cancer (DTC) who were evaluated as indeterminate response (IDR) after surgery and before 131I therapy. Methods:A total of 281 DTC patients (89 males, 192 females, age (38.4±10.2)years ) assessed as IDR before 131I therapy and after total or near-total thyroidectomy in the Department of Nuclear Medicine of Peking Union Medical College Hospital from April 2009 to March 2022 were retrospectively analyzed. Patients were divided into 131I therapy group ( 131I group) and just thyroid stimulating hormone (TSH) suppressive therapy group (TSH group) according to whether receiving 131I therapy, and the efficacies of two groups at the end of follow-up were compared. Subgroup analysis was conducted in different risk stratifications (low-risk, moderate-risk and high-risk), positive thyroglobulin antibody (TgAb) group (TgAb≥115 kU/L) and negative TgAb group (TgAb<115 kU/L). For patients with positive TgAb, the duration and rate for TgAb declining to negative level under the 2 regimens were compared. Independent-sample t test, Mann-Whitney U test, χ2 test and Fisher exact test were performed to compare the differences between groups. Results:Median follow-up time was 39(6-146) months. There was no statistical difference between patients in 131I group and TSH group in baseline characteristics, and the efficacies at the end of follow-up was similar between the 2 groups ( χ2=6.50, P=0.075). For low-, moderate- and high-risk stratification, there were also no statistical differences of response to 2 regimens ( P=0.221; χ2=4.21, P=0.223; χ2=3.01, P=0.274). Similar results were showed for patients with positive and negative TgAb ( n=50, n=231; χ2=4.02, P=0.242; χ2=3.14, P=0.341). For patients with positive TgAb, the duration and rate for TgAb declining to negative level were not statistically different either between 2 regimens (71.0%(22/31) vs 14/19, χ2=0.04, P=0.836; 7.0(5.0, 9.3) vs 7.0(5.0, 7.3) months, z=-0.89, P=0.375). Conclusion:For DTC patients assessed as IDR after surgery, 131I therapy may not provide more benefit than follow-up with TSH suppressive therapy.

ObjectiveTo evaluate the effectiveness and safety of neck seven-line method combined with periauricular acupuncture as salvage treatment for sudden hearing loss in non-acute stage. MethodsSixty-six patients with non-acute stage of sudden hearing loss with a disease duration of 15-90 days were randomly divided into 33 cases each in treatment group and control group. The treatment group was given neck seven-line method combined with acupuncture at periauricular points； the control group used sham acupuncture and sham electroacupuncture at the same points. Both groups were treated 3 times a week for 6 weeks. The pure tone average hearing threshold of impaired frequencies were examined before treatment， after treatment finish and at follow-up （week 10）， and the difference between pure tone average hearing threshold of impaired frequencies before and after treatment was calculated； calculate the proportion of patients with ≥10 dB improvement in pure tone average hearing threshold of impaired frequency after treatment and at follow-up； compare the patients' Tinnitus Evaluation Scale （TEQ） scores， Chinese Medicine Quality of Life Assessment Scale （CQ-11D） health utility values and the difference between before and after treatment， and record the occurrence of adverse events. ResultsThe pure tone average of impaired frequency in the treatment group were （50.57±18.07） dB and （47.70±17.42） dB at post-treatment and follow-up respectively， and （54.38±21.77） dB and （53.36±20.99） dB in the control group at post-treatment and follow-up. Compared with the pre-treatment period， the pure tone average hearing threshold of impaired frequency in the two groups significantly decreased （P＜0.05） at post-treatment and follow-up. The difference of pure tone average hearing threshold of impaired frequency in the treatment group after treatment and at the follow-up visit compared to that before treatment was lower than those in the control group （P＜0.05）. After treatment， 13 patients （39.39%） in the treatment group and 10 patients （30.30%） in the control group showed improvement of ≥10 dB in pure tone average hearing threshold of impaired frequency； at the follow-up visit， 18 patients （54.55%） in the treatment group and 10 patients （30.30%） in the control group showed improvement of ≥10 dB in the pure tone average hearing threshold of impaired frequency， and there was no statistical significance for comparison between groups at the time of post-treatment and follow-up （P＞0.05）. The TEQ score of the treatment group significantly lower than that before treatment （P＜0.05）； the TEQ score of the treatment group and the difference between before and after treatment significantly lower than that of the control group （P＜0.05）. The difference in CQ-11D health utility values and the difference between before and after treatment were not statistically significant between the two groups （P＞0.05）. Eight cases of acupuncture-related adverse events occurred among 66 patients， including subcutaneous haematomas after needling， severe pain during needling and needle fainting， which disappeared after symptomatic treatment and did not affect the following treatment. ConclusionNeck seven-line method combined with periauricular acupuncture could be used as salvage treatment for sudden hearing loss in non-acute stage to improve the pure tone average hearing threshold of impaired frequency， alleviate tinnitus， with safety.
