Objective This study aims to analyze the factors influencing benefit finding among cervical cancer patients and their spouses,as well as the interconnections between these factors.The goal is to provide a foundation for developing targeted clinical interventions.Methods Using the convenience sampling method,cervical cancer patients and spouses of 245 pairs who attended or were hospitalized in a tertiary-level hospital in Taiyuan City from October 2022 to July 2023 were selected as study subjects.Data were collected using a general information questionnaire,the Distress Disclosure Index,the Connor-Davidson Resilience Scale,and the Benefit Finding Scale.Univariate analysis,Pearson correlation analysis,and multiple linear regression were employed to scrutinize the data,leading to the establishment of Actor-Partner Interdependence Model.Results Benefit finding scores for cervical cancer patients and their spouses were(65.31±7.94)and(69.87±9.63),respectively.Multiple linear regression revealed that the educational level of patients and their spouses,whether or not they received chemotherapy or radiotherapy,self-disclosure and psychological resilience were the factors that affected patients'benefit finding.Spouse's education level,occupation,self-disclosure,psychological resilience and patients'self-disclosure and psychological resilience were the influencing factors of spouse's benefit finding.The Actor-Partner Interdependence Model analysis indicated that the self-disclosure and psychological resilience of cervical cancer patients positively predicted their own benefit finding and that of their spouses(path coefficients were 0.415,0.501,0.216,and 0.168,respectively,all P＜0.05).However,spouses'self-disclosure and psychological resilience could only positively predict their own benefit finding(path coefficients were 0.188 and 0.254,respectively,all P＜0.05).Conclusion Benefit finding among cervical cancer patients and their spouses is moderate and influenced by various factors.Both self-disclosure and psychological resilience of cervical cancer patients and their spouses have positive subjective effects on their own benefit finding.Healthcare professionals should encourage both parties to engage in healthy interactions about the disease,take steps to increase the level of psychological resilience of both,and ultimately tap into a higher level of benefit finding.

Objective:To summarize the best evidence for the management of lower urinary tract dysfunction (LUTD) in total hysterectomy patients, so as to provide evidence-based basis for clinical practice.Methods:According to the "6S" pyramid model, literature related to the management of LUTD in total hysterectomy patients was successively searched from guide websites, evidence-based websites, professional websites and comprehensive databases. The search deadline was from the establishment of the databases to March 31, 2023. Two researchers evaluated the quality of the included literature, extracted evidence and recommended the level of evidence.Results:A total of 14 articles were included, including one clinical decision, two evidence summaries, three guidelines, one expert consensus and seven systematic evaluations. A total of 25 pieces of evidence were summarized from four aspects, such as symptom assessment, urinary tract management, symptom intervention and health education.Conclusions:Medical staff should manage lower urinary tract dysfunction in patients undergoing total hysterectomy based on evidence-based evidence to prevent or reduce the occurrence of lower urinary tract dysfunction in patients.

Objective:To explore the different categories of family resilience in cervical cancer patients and their influencing factors.Methods:From October 2022 to September 2023, 275 cervical cancer patients admitted to the First Hospital of Shanxi Medical University were selected as the study subject by convenience sampling. Cervical cancer patients were surveyed using the self-made General Information Questionnaire, Benefit Finding Scale (BFS), Connor-Davidson Resilience Scale (CD-RISC), and shortened Chinese Version of the Family Resilience Assessment Scale (FRAS-C). Latent profile analysis was used to investigate the family resilience of patients, and Logistic regression was used to analyze the influencing factors of family resilience in different categories.Results:A total of 275 questionnaires were distributed, and 253 valid questionnaires were collected, with a valid response rate of 92.0% (253/275). Family resilience of cervical cancer patients was divided into three categories of low resilience-negative coping group (18.6%, 47/253), moderate resilience-communication disorder group (59.3%, 150/253), and high resilience-inclusive understanding group (22.1%, 56/253). The per capita family monthly income, place of residence, primary caregivers, whether to undergo radiotherapy or chemotherapy, psychological resilience, and disease benefit finding were the influencing factors of family resilience in different categories of cervical cancer patients ( P<0.05) . Conclusions:The family resilience of cervical cancer patients can be divided into three latent categories. Medical and nursing staff should identify the characteristics of different categories of patients and provide targeted intervention measures to improve their family resilience.

In order to understand the difference and expression of genes in CEK cells before and af-ter baicalin interferes with IBV,further reveal and analyze the mechanism of baicalin interfering IBV replication in CEK cells in vitro.After IBV infected CEK cells for 2 h,9.75 mg/L baicalin liq-uid was added to interfere with CEK cells,which was recorded as the baicalin(H-IBV)group,and three replicate wells were set in the control group and the IBV(IBV)infection group.After 36 h culture,cell samples were collected and subject to transcriptome for sequencing.The results showed that there were 102 differentially expressed genes in H-IBV group compared with IBV in-fection group,among which 48 genes weresignificantly up-regulated and 54 genes were significantly down-regulated.Through functional annotation in GO and KEGG databases,it was found that dif-ferentially expressed genes were mainly annotated in biological processes such as cellular proces-ses,biological regulation,metabolism,and secondary pathways such as viral infectious diseases,signal transduction and interaction.Retinol metabolism pathway,phospholipid transfer to mem-brane,IL-27 mediated signaling pathway,MDA5/RIG-I and Toll-like receptor signaling pathway were significantly enriched in CEK cells,and the production of type Ⅰ interferon and interferon al-pha and the process of antiviral infection were also positively regulated.There were more differen-tial genes enriched in nucleic acid catalysis,immune system,and reaction,and interbiological reac-tion.Through the STRING network interaction map,it was found that most immune-related genes could form a 36-node interaction network centered on IRF7,TLR3 and STAT1.Therefore,com-pared with IBV group,the differentially expressed genes after baicalin treatment were mainly an-notated and enriched in the biological process,and the immune system and response were en-hanced,mainly through the positive regulation of IRF7 in the MDA5/RIG-I receptor signaling pathway and the inhibition of TLR3 signal transduction in the Toll-like receptor signaling path-way.Positive regulation of IL-27 mediated pathway and regulation of JAK-STAT signaling path-way were supplemented by activation of the expression of IRF7,TLR3,STAT1 and other related genes,and interaction with corresponding downstream proteins to promote the expression of IFN-α and regulatory cytokines,coupled with negative regulation of viral(defense)response and viral processes.Thus,baicalin interferes with IBV replication in CEK cells.

Objective To evaluate which factors may affect magnetic resonance imaging(MRI)performance in the detection of pathologic complete response(pCR)after neoadjuvant chemotherapy(NAC).Methods This retrospective study involved 89 patients diagnosed with invasive breast carcinoma who received NAC at The Second Affiliated Hospital of Xi'an Jiaotong University from July 2019 to December 2021.Breast MRI was performed before and after NAC.Based on the pathological results obtained surgery after the completion NAC and using Miller-Payne classification as the evaluation standard,the patients were divided into two subgroups:pCR and non-pathological complete response(npCR).Chi-square test was used to compare the MRI characteristics of pre-NAC lesions between the two groups.ROC curve analysis was made to analyze the accuracy,sensitivity,specificity,positive predictive value,and negative predictive value of MRI after NAC;the diagnostic performance of MRI in predicting pCR in different tumor subtypes was analyzed.We made univariate and multivariate analyses of factors affecting radiographic complete response(rCR)and pCR concordance.Results MRI analysis after NAC showed rCR in 20 cases(22.5％)and pCR in 28 cases(31.5％).Considering rCR as a"positive"result of MRI analysis,MRI assessment was accurate in 79 cases,including 19 true positive cases and 60 true negative cases.MRI assessment was inaccurate in 10 cases,including 9 false negative cases and 1 false positive case.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MRI assessment of pCR were 67.86％,98.36％,88.76％,95.00％,and 86.96％.MRI had the lowest diagnostic efficiency in evaluating pCR of ERBB2+breast cancer after NAC.Single factor analysis showed that estrogen receptor(ER),clinical stage,background parenchymal enhancement,and maximum tumor diameter all affected the consistency of rCR and pCR(P＜0.05).Multivariate Logistic regression analysis showed that the independent influencing factor affecting the consistency of rCR and pCR was clinical stage.Conclusion MRI demonstrated good accuracy in predicting pCR after NAC in the breast cancer patients examined.Pre-treatment MRI characteristics and tumor subtypes may be related to the diagnostic accuracy of post-NAC MRI in breast cancer patients.

Background: and Purpose This study aimed to determine the changes in cerebral blood flow (CBF) in patients who received different durations of hemodialysis (HD) using arterial spin labeling magnetic resonance imaging. Methods: The study included 46 patients who received HD and 24 demographically similar healthy controls (HCs). Patients who received HD were divided into three subgroups based on its duration: HD-1 (n=15, dialysis duration ≤24 months), HD-2 (n=16, dialysis duration >24 and ≤72 months), and HD-3 (n=15, dialysis duration ≥73 months). All subjects completed the Mini Mental State Examination and Montreal Cognitive Assessment tests, and the patients who received HD underwent laboratory tests. Group-level differences in the global and regional CBFs between patients who received HD and HCs were assessed. Correlation analysis was performed to evaluate the associations among CBF, clinical variables, and cognitive function. Results: Compared with HCs, global and regional CBFs were significantly increased in the HD-1 and HD-2 groups (p<0.05), but there was no significant difference in the HD-3 group (p>0.05). However, compared with the HD-1 group, the HD-3 group had significantly decreased global and regional CBFs (p<0.05). The cognitive function was worse in patients who received long-term HD than in HCs. Increased dialysis duration and hemoglobin level were predictive risk factors for decreased CBF in patients who received long-term HD. Conclusions Patients who received long-term HD with normal CBF had worse cognitive function, which may be related to increased dialysis duration.

Objective:To evaluate the efficacy by using domestic recombinant human thyroid-stimulating hormone (rhTSH) in patients with differentiated thyroid cancer (DTC) before or after 131I therapy. Methods:From May 2019 to November 2020, a total of 24 patients with DTC (5 males, 19 females, median age 41 years) in Peking Union Medical College Hospital and Affiliated Tumor Hospital of Zhengzhou University were enrolled into the open-label, dose escalation phase Ⅰ study. All patients were divided into 4 domestic rhTSH dose groups: 0.9 mg×1 d (group A), 0.9 mg×2 d (group B), 1.8 mg×1 d (group C), 1.8 mg×2 d (group D) in succession, with 6 patients in each group. Each patient underwent rhTSH phase and thyroid hormone withdrawal (THW) phase. The end point included safety, tolerability, the quality of life (hypothyroidism symptom and sign score (Billewicz score), profile of mood states (POMS)), effectiveness (thyroid-stimulating hormone (TSH) and thyroglobulin (Tg) levels, diagnostic whole-body scan (Dx-WBS)) and pharmacokinetic characteristics (peak time, peak concentration) of rhTSH. Paired t test and Wilcoxon signed rank test were used for statistical analysis. Results:There were no dose-limiting toxicities, serious adverse events, or no grade ≥3 adverse events reported. The quality of life in rhTSH phase was significantly better than those in THW phase, including the lower Billewicz score (-53.00(-53.00, -53.00) vs -39.50(-47.00, -23.00); S=119.50, P<0.001) and the lower POMS score (91.92±12.06 vs 99.67±19.13; t=0.95, P=0.025). Serum TSH level was increased from 0.04(0.02, 0.11) mU/L (baseline) to 150.00(105.20, 173.31) mU/L 24 h after the last rhTSH administration, which was increased along with the elevation of rhTSH doses. In the THW phase, patients′ TSH levels were≥30 mU/L after 23 d (median) of THW, with the median of 73.51(57.22, 106.22) mU/L. Median Tg level of baseline was 0.10(0.10, 0.41) μg/L, which reached a peak of 0.85(0.12, 3.01) μg/L at 48 h after rhTSH administration. The peak Tg level in the THW phase was 0.88(0.15, 8.04) μg/L. The Dx-WBS consistency rate between rhTSH and THW phase was 95.8%(23/24). Conclusion:rhTSH is a safe and effective method to stimulate the serum Tg level and radioiodine uptake in patients undergoing post-operation or post- 131I assessment for DTC, as well as maintain a higher quality of life in comparison to THW phase.

Objective:To investigate the clinicopathological characteristics of renal leukocyte chemotactic factor 2 amyloidosis (ALECT2).Methods:The patients with renal ALECT2 diagnosed by renal biopsy in Peking University First Hospital, Shanxi Medical University Second Hospital and Shanxi Bethune Hospital from January 2001 to October 2021 were retrospectively enrolled. According to whether the patients had concurrent glomerular diseases, they were classified into two groups: isolated ALECT2 group and ALECT2 with concurrent renal diseases group. Clinicopathological data of the two groups were compared. Light microscopy, immunofluorescence and immunoelectron microscopy were applied to investigate pathological characteristics of renal tissues. Mass spectrometry was used to analyze the composition of renal amyloid deposits. Gene sequencing was employed to detect the leukocyte chemotactic factor 2 ( LECT2) gene sequence in peripheral blood of the patients. Results:Sixteen patients with ALECT2 were enrolled in this study and nine of them had concurrent renal diseases. The age of 16 patients was (65.00±8.45) years old. The sex ratio of males to females was 7 to 9. Most of patients were Han ethnicity (15/16). Eight patients came from Shanxi province. Fifteen patients presented with varying degree of proteinuria [2.16(1.07, 4.72) g/24 h]; 5 patients had nephrotic syndrome; 11 patients had renal insufficiency; 12 patients had microscopic hematuria. Part of patients also had hypertension (12/16) and diabetics (6/16). Compared with isolated ALECT2, the ALECT2 group with concurrent renal diseases had a higher proportion of nephrotic syndrome (5/9 vs 0/7, P=0.034). Renal biopsy results showed that all patients (16/16) had amyloid deposits in the interstitium of renal cortex with varying degree of inflammatory cell infiltration and fibrosis, and glomeruli (12/16) and arterioles (14/16) were involved by amyloid deposits. The amyloid deposits were strongly congophilic and immunohistochemistry for LECT2 was positive. By semi-quantitative analysis, the proportions of glomerular and overall amyloid loads in ALECT2 with concurrent renal diseases group were lower than those in isolated ALECT2 group (both P<0.05). Electron microscopy revealed randomly oriented and non-branching fibrils with a diameter of 8-12 nm. The LECT2 peptides were detected by mass spectrometry in renal amyloid deposits of 8 patients, and homozygous G allele of LECT2 was found in 7 patients by gene sequencing. Complete follow-up data of 13 patients showed that 2 patients died, 1 patient developed end-stage renal disease at the time of renal biopsy, and most of the rest patients had stable renal function (8/10). Conclusions:Patients with renal ALECT2 mainly present with proteinuria, along with a high incidence of renal insufficiency, microscopic hematuria, and concurrent renal diseases. The pathologic feature is the preferential deposition of amyloid in renal cortical interstitium.

Objective To discuss the BRAF V600E mutation rate in papillary thyroid carcinoma (PTC) and its relationship with the clinicopathological features. Methods Two hundred and sixty-five PTC patients(including 226 cases of classical type,29 cases of follicular type, 3 cases of high cell type, 2 cases of diffuse sclerosis type, 2 cases of eosinophilic type, 3 cases of cystic type) from August 2014 to October in Shanxi Provincial Cancer Hospital, were collected with completely clinical and pathological information. The BRAF V600E mutation was detected by real-time polymerase chain reaction (RT-PCR) method. Pearson χ 2 test and the exact probability method were used to analysis the relationship between gene mutations and clinicopathological data. Results BRAF V600E mutation rate in PTC patients was 73.21 %(194/265). There was no significant difference in the mutation rate of BRAF V600E among patients with different age, gender, tumor location,tumor number and extravaginal invasion(all P>0.05),but the mutation rates of BRAF V600E gene in patients with different tumor size, histopathological subtypes, lymph node metastasis and clinical stage were significantly different(all P<0.05).Conclusion The PTC patients with positive BRAF V600E mutation have poor clinicopathological features,and BRAF V600E mutation may be a predictor of advanced PTC.

OBJECTIVETo assess the association of methylenetetrahydrofolate reductase (MTHFR) gene 677C to T polymorphism with blood homocysteine (Hcy) level among women of childbearing age from Shiyan area.

METHODSPCR-chip hybridization was used to determine the genotype of MTHFR 677C to T, and a biochemical assay was used to determine the total Hcy level among 428 healthy women of childbearing age. Association of MTHFR 677C to T with total Hcy level was assessed.

RESULTSHeterozygous CT mutation was most common form for the MTHFR 677C to T polymorphisms and amounted for 49.77% among the group, while the CC wild type and homozygous TT mutation respectively accounted for 30.61% and 19.63%. These gave a frequency of 44.51% for the 677T allele. The dominant genotype among different age groups were the CT type. Of note, the proportion of MTHFR 677CC is higher in women above 30 years of age. The distribution of MTHFR 677C to T genotypes has differed significantly among different age groups (P<0.05). Compared with those with wild type alleles, carriers of MTHFR mutations had a higher plasma Hcy level. The genotypic frequencies of MTHFR C677T in Shiyan region differed significantly from those of Sichuan, Hebei, Henan and Shandong (P<0.05) but were similar to those of Jiangsu, Guangdong, Ningxia and Xinjiang.

CONCLUSIONThe distribution of MTHFR C677T polymorphism among women of childbearing age in Shiyan area is influenced by age and is geographically specific and associated with plasma Hcy level. Nearly 50% of women have carried the high risk alleles, for whom folic acid supplementation is crucial for the reduction of birth defect rate.
