Objective:To investigate the alterations in brain functional activity before and after chemotherapy in breast cancer patients with chemotherapy-related cognitive impairment (CRCI) using resting-state functional magnetic resonance imaging (rs-fMRI) and their relations with cognitive impairment.Methods:A prospective observational study was performed; female breast cancer patients with CRCI admitted to Department of Oncology, Affiliated Hospital 6 of Nantong University were recruited, and age- and education level-matched female healthy controls were chosen. Before and one month after chemotherapy, statuses of cognitive function, depression and anxiety in breast cancer patients with CRCI were evaluated by Montreal cognitive assessment (MoCA), functional assessment of cancer therapy-cognitive function (FACT-cog), self-rating depression scale (SDS), and self-rating anxiety scale (SAS); subsequently, conventional MRI and resting-state functional magnetic resonance imaging (rs-fMRI) were conducted. The healthy controls accepted MoCA, SDS, and SAS, followed by conventional MRI and rs-fMRI. Differences in clinical data and amplitude of low-frequency fluctuation (ALFF, rs-fMRI brain spontaneous neural activity index) were compared between breast cancer patients with CRCI before chemotherapy and healthy controls, and in the breast cancer patients with CRCI between before and after chemotherapy. Taking the brain regions with significant differences in ALFF before and after chemotherapy in breast cancer patients with CRCI as seed points, the difference in whole-brain functional connectivity (FC) before and after chemotherapy was compared in breast cancer patients with CRCI. Pearson or Spearman correlation tests were used to analyze the correlations of ALFF and FC in brain regions with significant differences in ALFF with cognitive function scores in breast cancer patients with CRCI.Results:(1) A total of 22 breast cancer patients with CRCI and 22 healthy controls were enrolled. Compared with the healthy controls, the breast cancer patients with CRCI before chemotherapy had significantly higher SDS and SAS scores ( P<0.05). Compared with breast cancer patients with CRCI before chemotherapy, the breast cancer patients with CRCI after chemotherapy had significantly lower MoCA, FACT-cog-perceived cognitive impairment, FACT-cog-comment from others on cognitive function, and FACT-cog-perceived cognitive ability ( P<0.05). (2) Compared with those before chemotherapy, breast cancer patients with CRCI after chemotherapy exhibited significantly increased ALFF in the right precuneus, right middle occipital gyrus, and left superior frontal gyrus, while statistically decreased FC in the right middle occipital gyrus-left middle temporal gyrus, right precentral gyrus-right middle temporal gyrus, and left superior frontal gyrus-left fusiform gyrus ( P<0.05). (3) ALFF in the right precentral gyrus in breast cancer patients with CRCI after chemotherapy was negatively correlated with difference value of FACT-cog before and after chemotherapy ( r=-0.497, P=0.018) and difference value of PCA before and after chemotherapy ( r s=-0.436, P=0.042); FC in the left superior frontal gyrus-left fusiform gyrus was positively correlated with score of FACT-cog-perceived cognitive impairment ( r=0.621, P=0.002). Conclusion:Chemotherapy induces compensatory enhancement of spontaneous neural activity in multiple brain regions in breast cancer patients with CRCI, accompanied by FC disruption at specific brain areas, which are associated with cognitive impairment.

Objective:To explore the effect of hospital-community continuous management based on mobile health and dyadic coping intervention in ileostomy patients and their spouses.Methods:This was a randomized controlled trial. Patients with rectal cancer who underwent ileostomy at Taizhou People′s Hospital between August 2018 and August 2023, along with their spouses, were enrolled. Patient-spouse dyads were randomly assigned to either the intervention group or the control group using a random number table method. Baseline demographic data were collected from both groups. The control group received routine care, whereas the intervention group was given a hospital-community transitional care program based on mHealth (mobile health) and a dyadic coping model. Stoma adaptation, family functioning, and dyadic coping capacity were evaluated at 1 week, 1 month, and 3 months postoperatively. Sedentary behavior time and exercise compliance were also assessed at 1 month and 3 months after surgery.Results:A total of 47 patient-spouse dyads were included in the control group and 48 dyads in the intervention group. There were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). Similarly, no significant differences were found in the age, sex or education level of the spouses (all P>0.05). At 1 week postoperatively, there were no significant differences in family cohesion and adaptability scores between the two groups (all P>0.05). However, at 1 and 3 months postoperatively, the intervention group had significantly higher family cohesion and adaptability scores than the control group (all P<0.05). With regard to dyadic coping capacity, no significant differences were observed in any of the subscale scores of the dyadic coping questionnaire at 1 week postoperatively (all P>0.05). At 1 and 3 months postoperatively, the intervention group scored significantly higher than the control group on stress communication, supportive coping, delegated coping, and joint coping ( P<0.05), but lower on negative coping ( P<0.05). In terms of stoma adaptation, no significant difference was found between the two groups at 1 week postoperatively ( P>0.05). At 1 and 3 months postoperatively, the intervention group showed significantly higher stoma adaptation and exercise compliance scores, as well as shorter sedentary behavior time, compared to the control group (all P<0.05). Conclusions:The hospital-community transitional care program developed by the research team effectively improves family functioning, dyadic coping capacity in ileostomy patient-spouse dyads, and postoperative stoma adaptation and rehabilitation outcomes.

BACKGROUND:Allogeneic hematopoietic stem cell transplantation is an important treatment for malignant hematological diseases,and delayed postoperative platelet implantation is a common complication that seriously affects the quality of patient survival;however,there are no standard protocols to improve platelet implantation rates and prevent platelet implantation delays. OBJECTIVE:To compare the safety and efficacy of oral Herombopag Olamine versus subcutaneous recombinant human thrombopoietin for promoting platelet implantation in patients with malignant hematological diseases undergoing haploid hematopoietic stem cell transplantation. METHODS:Clinical data of 163 patients with malignant hematological diseases who underwent haploidentical hematopoietic stem cell transplantation from January 2016 to October 2022 were retrospectively analyzed.A total of 72 patients who started to subcutaneously inject recombinant human thrombopoietin at+2 days were categorized into the recombinant human thrombopoietin group;a total of 27 patients who started to orally take Herombopag Olamine at+2 days were categorized into the Herombopag Olamine group;and 64 patients who did not apply Herombopag Olamine or recombinant human thrombopoietin were categorized into the blank control group.The implantation status,incidence of acute graft-versus-host disease of degree II-IV within 100 days,1-year survival rate,1-year recurrence rate,and safety were analyzed in the three groups. RESULTS AND CONCLUSION:(1)The average follow-up time was 52(12-87)months.The implantation time of neutrophils in the blank control group,recombinant human thrombopoietin group,and Herombopag Olamine group was(12.95±3.88)days,(14.04±3.71)days,and(13.89±2.74)days,respectively,with no statistically significant difference(P=0.352);the implantation time of platelets was(15.16±6.27)days,(17.67±6.52)days,and(17.00±4.75)days,with no statistically significant difference(P=0.287).(2)The complete platelet implantation rate on day 60 was 64.06%,90.28%,and 92.59%,respectively,and the difference was statistically significant(P<0.001).The subgroup analysis showed that the difference between the blank control group and the recombinant human thrombopoietin group was statistically significant(P<0.001),and the difference between the blank control group and the Herombopag Olamine group was statistically significant(P=0.004).The difference was not statistically significant between the recombinant human thrombopoietin group and Herombopag Olamine group(P=0.535).(3)100-day II-IV degree acute graft-versus-host disease incidence in the blank control group,recombinant human thrombopoietin group,and Herombopag Olamine group were 25.00%,30.56%,and 25.93%,respectively,and the difference was not statistically significant(P=0.752).(4)The incidence of cytomegalovirus anemia,cytomegalovirus pneumonia,and hepatic function injury had no statistical difference among the three groups(P>0.05).(5)During the follow-up period,there was no thrombotic event in any of the three groups of patients.(6)The results showed that recombinant human thrombopoietin and Herombopag Olamine could improve the platelet implantation rate of malignant hematological disease patients after haploidentical hematopoietic stem cell transplantation,with comparable efficacy and good safety.

Objective To identify independent predictors of prognosis in MMNS and to examine the expression of CD4,CD8,CD20 and their relationship with prognosis.Methods 87 patients with MMNS were retrospectively an-alyzed to summarize their clinicopathologic characteristics;the expression of CD4,CD8,and CD20 in MMNS were observed by EnVision immunohistochemical staining(IHC)to analyze the relationship between the expression of these markers and prognosis.Results MMNS with sinus,surrounding tissue invasion,larger tumor and higher AJCC stage showed a worse prognosis.No significant correlation was found among sex,age,histological type,melanin granules,mitotic figures and survival rate.The counts of CD4+,CD8+and CD20+TILs in intra-tumoral stroma were positively correlated with the density of TILs at the base of the tumor.CD20+B cells did not have a central tendency to aggregate to form tertiary lymphoid structures,whether in the intratumoral stroma or in the basal stroma of the tumor,the three cell subsets were admixed.There was no statistically significant difference in OS be-tween CD4+,CD8+,and CD20+subsets.Conclusions The number of CD20+B cells was significantly less than that of CD4+and CD8+T cells in both the intratumoral stroma and the basal stroma of the tumor,and tertiary lymphoid structures fail to be formed,which,unlike cutaneous malignant melanoma,might be a cause of the poor prognosis of MMNS.

Objective To explore the impact of family sandplay therapy based on the narrative concept on family resilience and sense of meaning in life among gastric cancer patients.Methods A total of 104 gastric cancer patients were selected and randomly divided into control group and experi-mental group,with 52 patients in each group.The control group received routine nursing care,while the experimental group received family sandplay therapy based on the narrative concept in addition to routine nursing care.Both groups were assessed using the Chinese Family Resilience Assessment Scale(C-FRAS)and the Chinese Meaning in Life Questionnaire(C-MLQ)before the intervention and at 1 month and 3 months post-intervention.The scores of scales were compared.Results After interven-tion,the total C-FRAS score and score of each dimension were higher in the experimental group than those in the control group,and both the total C-FRAS score and score of each dimension showed an upward with time extension.The total C-MLQ score and score of each dimension were also higher in the experimental group compared with the control group(P＜0.05).Conclusion Family sandplay therapy based on the narrative concept can enhance family resilience and sense of meaning in life a-mong gastric cancer patients.

Objective:Based on data from the Global Burden of Disease Study 2021 (GBD 2021), this study aims to analyze the epidemiological trends of inflammatory bowel diseases (IBD) in China from 1990 to 2021 and to assess the projected disease burden.Methods:Data on incidence, prevalence, mortality, and disability-adjusted life years (DALY) for IBD in China from 1990 to 2021 were extracted from the GBD 2021 database. Annual percent change (EAPC) and Bayesian age-period-cohort (BAPC) analyses were employed to evaluate these trends. Additionally, predictions for the disease burden over the next 25 years were made.Results:The age-standardized incidence rate of IBD in China rose from 0.74 per 100 000 in 1990 to 1.40 per 100 000 in 2021, an 89.19% increase. The age-standardized prevalence rate increased from 5.59 per 100 000 in 1990 to 9.16 per 100 000 in 2021, marking a 63.86% rise. Conversely, the age-standardized case fatality rate decreased from 0.75 per 100 000 in 1990 to 0.33 per 100 000 in 2021, a reduction of 56.00%. The total DALYs decreased from 162 186 in 1990 to 136 932 in 2021, a decline of 15.57%, while the age-standardized DALY rate fell from 18.38 per 100 000 in 1990 to 7.68 per 100 000 in 2021, a decrease of 58.22%. Analysis by age group revealed that the age-standardized incidence rate for the 35-39 years cohort increased most significantly, with an EAPC of 3.23%. The age-standardized prevalence rate for the 50-54 years cohort increased most significantly, with an EAPC of 2.85%. Gender analysis indicated that from 1990 to 2021, the age-standardized prevalence rate was higher among females than males, but the age-standardized case fatality rate rate was higher among males. From 2004 to 2021, the age-standardized DALY rate declined for both sexes, though it remained higher in males. By 2046, the number of new cases is projected to be slightly higher in males, while case fatality rate and DALYs are expected to remain low for both genders.Conclusions:Over the past three decades, the disease burden of IBD in China has increased significantly, particularly in terms of incidence and prevalence. Despite a general decrease in case fatality rates, the burden of IBD may increase in the elderly population due to aging demographics. Therefore, effective preventive measures, early screening, and aggressive treatment are crucial, especially for the elderly.

Objective:To investigate the correlationship between an artificial intelligence-based e-Boston bowel preparation scale (e-BBPS) system score and the adenoma miss rate.Methods:Colonoscopy images of 4 373 patients at the Endoscopy Center of Renmin Hospital of Wuhan University from December 21, 2017 to December 31, 2019 were collected for model training. Patients who underwent colonoscopy at the Eighth Affiliated Hospital of Sun Yat-sen University from October 8, 2021 to November 9, 2022 were prospectively included. Patient's bowel preparation was evaluated by the e-BBPS system and endoscopists based on BBPS score. If both the endoscopists and e-BPPS system believed that the bowel preparation was sufficient, the patient immediately proceeded to a second colonoscopy. Otherwise, the patient underwent bowel preparation again. The differences in adenoma and polyp miss rate between the qualified group (e-BBPS system score ≤3) and the unqualified group (e-BBPS system score >3) were compared.Results:The adenoma miss rate in the qualified group was significantly lower than that in the unqualified group [26.72% (62/232) VS 42.53% (37/87), χ2=7.384， P=0.007, OR=2.029 (95% CI: 1.212-3.396)], and the polyp miss rate in the qualified group was significantly lower than that in the unqualified group [27.28% (195/702) VS 41.24% (113/274), χ2=16.539， P<0.001, OR=1.825 (95% CI: 1.363-2.443)]. Conclusion:The deep learning-based e-BBPS system demonstrates accuracy and reliability in bowel preparation assessment, offering potential to standardize the process of evaluating bowel preparation and reduce missed lesions.

Objective:To analyze differences in detection rates for gastric precancerous lesions and neoplasms before versus after implementing a computer-aided detection (CADe) system in real-world clinical practice.Methods:Clinical data of patients who underwent gastroscopic examinations in two examination rooms (Room 1 and 2) in the Digestive Endoscopy Center of Renmin Hospital of Wuhan University were retrospectively collected during two periods: from January to June 2018 and from January to June 2021. Patients were stratified into four groups: CADe group (Room 2, 2021, using CADe), Pre-CADe group (Room 2, 2018, without CADe), 18-Con group (Room 1, 2018, without CADe), and 21-Con group (Room 1, 2021, without CADe). The differences in the detection rates of intestinal metaplasia and neoplasms between different groups were compared.Results:The detection rate of intestinal metaplasia in the CADe group was significantly higher than that in the Pre-CADe group [5.76% (198/3 437) VS 3.23% (100/3 092), χ2=23.856, P<0.001]. It was also significantly higher than that in the 21-Con group [5.76% (198/3 437) VS 2.73% (131/4 796), χ2=47.895, P<0.001]. The detection rate of neoplasms in the CADe group was significantly higher than that in the Pre-CADe group [3.23% (111/3 437) VS 1.58% (49/3 092), χ2=18.421, P<0.001] and the 21-Con group [3.23% (111/3 437) VS 1.79% (86/4 796), χ2=17.687, P<0.001]. Conclusion:The CADe system can significantly improve the detection rates of gastric intestinal metaplasia and neoplasms in clinical settings, potentially facilitating early diagnosis and treatment.

To study the microbiological contamination of endoscopic forceps channel at the time of reception and after disinfection, and gain a preliminary understanding of their real disinfection quality, then analyse the problems and make recommendations. A total of 115 endoscopes received at Renmin Hospital of Wuhan University from June 2022 to December 2023 were chosen. Microbiological sampling and strain identification of the endoscopic forceps channel were carried out at the time of reception of the endoscopes and after cleaning and disinfection, respectively, then the qualified disinfection rate and microbial detection rate were compared. The overall qualified disinfection rate after cleaning and disinfection of endoscopes received (91.3%, 105/115) was higher than that at reception (57.4%, 66/115, χ 2=37.026, P<0.001). The overall microbiological detection after cleaning and disinfection of endoscopes received (13.0%, 15/115) was lower than that at reception (48.7%, 56/115, χ 2=41.000, P<0.001), the detection rate of high pathogenic organisms after cleaning and disinfection (7.0%, 8/115) was lower than that at reception (29.6%, 34/115, χ 2=24.039, P<0.001), low pathogenic organisms after cleaning and disinfection (6.1%, 7/115) was lower than that at reception (19.1%, 22/115, χ 2=13.067, P<0.001). At the time of reception, the qualified disinfection rate was low and the microbiological detection rate was high, and there may become a greater risk of cross-infection; after cleaning and disinfection, the qualified disinfection rate was increased and the microbiological detection rate was decreased, which may greatly reduce the risk of patient infection. Therefore, it is recommended that attention should be paid to the disinfection quality monitoring of endoscopes received before putting into clinical use.
