Objective Exploring the effect of Bian-stone-based herbal heat therapy on herbal heat ironing in gastrointestinal reactions during the preconditioning period of hematopoietic stem cell transplantation patients.Methods Convenience sampling method was used to select 68 cases of hematopoietic stem cell transplantation patients who attended the hematology department of a tertiary-level Chinese medicine hospital in Hangzhou from October 2023 to April 2024 as the study subjects,and the SPSS 26.0 statistical software was used to generate a random number for grouping into an experimental and a control group,with 34 cases in each group.On the basis of intravenous antiemetic medication and routine,the experimental group implemented the Bian-stone-based herbal heat therapy on the basis of intravenous antiemetic medication and conventional nursing care.In the control group,intravenous antiemetic drugs and routine care were used,and the intervention duration of both groups was 14 d,of which 7 d was a course of treatment,with a total of 2 courses of treatment.The incidence of gastroin-testinal reactions,Gastrointestinal Symptom Rating Scale(GSRS)score,Pepsin Ⅰ(PG Ⅰ),Pepsin Ⅱ(PG Ⅱ),and the ratio of PG Ⅰ to PG Ⅱ(PGR)before and after the intervention were compared between the 2 groups.Results The final sample of 66 cases was collected in this study,and 1 patient was dislodged from each of the control group and the experimental group.The comparison of the incidence of gastrointestinal reactions between the 2 groups within 14 days showed that the incidences of nausea,vomiting,abdominal distension,and diarrhea were lower in the experimental group than those in the control group(P＜0.05).GSRS scores on days 1,8,and 14 of intervention were compared,and there were effects between groups in both groups(F=5.338,P=0.017).The levels of PG Ⅰ,PG Ⅱ in the experimental group on day 8 of the intervention were lower than those in the control group.The levels of PGR was higher than that in the control group(all P＜0.05).The safety of the 2 groups after treatment was evaluated,and the results showed that no serious adverse events occurred in the 2 groups.Conclusion Bian-stone-based herbal heat therapy can improve gastrointestinal reactions and reduce the incidence of gastrointestinal reactions during the preconditioning period of hematopoietic stem cell transplantation patients,which provides clinical guidance for the application of Bian-stone-based herbal heat therapy by nursing staff in the future.

Objective:To evaluate the role of whole exome sequencing（WES）in the etiological diagnosis and precision medicine management of patients with urolithiasis.Methods:We conducted a retrospective review of 21 patients with urolithiasis and pathogenic gene mutations identified by WES at The Second Affiliated Hospital of Zhengzhou University between April 2019 and March 2025. The cohort included 13 males and 8 females，with a mean age of（18.9 ± 11.1）years；18 patients were under 25 years old. Clinical presentations included nephrocalcinosis（8 patients）and urinary tract calculi（13 patients），with five patients exhibiting extra-renal manifestations such as renal tubular acidosis and hyperaldosteronism. Stone composition analysis identified calcium oxalate（16 patients），cystine（4 patients），and carbonate apatite（1 patient）. Metabolic abnormalities were prevalent，including hypocitraturia（11 patients），hyperoxaluria（8 patients），and hypercalciuria（7 patients），with eight patients presenting two or more concurrent disorders. All patients underwent WES and comprehensive metabolic evaluation. Sequencing was performed on an Illumina Hiseq4000 platform，achieving a mean depth of > 100× and coverage of > 98% in target regions. Variants were classified according to the American College of Medical Genetics and Genomics（ACMG）guidelines.Results:WES identified 12 distinct genes across autosomal recessive（9 genes： AGXT， GRHPR， ATP6V1B1， SLC12A1， KCNJ1， SLC3A1， SLC7A9， SLC34A3， WFS1），autosomal dominant（2 genes： CASR， ADCY10），and X-linked recessive（1 gene： CLCN5）inheritance patterns. Genotype-phenotype correlations revealed mutations associated with primary hyperoxaluria（8 patients），hypercalciuria（7 patients），and renal malformation due to a WFS1 mutation（1 patient）. A positive genetic diagnosis was achieved in 100% of patients with either urinary oxalate > 1 000 μmol/24 h or cystine stones. 8 patients received a diagnosis of hereditary stone disease at their first presentation（non-delayed group），while 13 experienced a mean diagnostic delay of（9.6 ± 3.9）years. The delayed diagnosis group had a significantly older age at initial stone onset［（10.2 ± 5.3）years vs.（6.8 ± 3.1）years， P = 0.03］and a higher incidence of impaired renal function（6 patients vs. 1 patient， P = 0.04）. Analysis of diagnostic delay by gene subgroup showed delays in 2/4 patients with cystinuria［ SLC3A1/ SLC7A9；（8.2 ± 3.5）years］，5/8 with primary hyperoxaluria［ AGXT/ GRHPR；（10.5 ± 4.1）years］，5/7 with hypercalciuria-related genes［ CASR/ ADCY10/ SLC12A1/ KCNJ1/ SLC34A3；（9.8 ± 3.8）years］，and 1/2 with other genes［ ATP6V1B1/ WFS1/ CLCN5；（7.6 ± 2.2）years］. Among 32 mutation sites detected，21 were classified as pathogenic/likely pathogenic and 11 as variants of uncertain significance. Four novel mutations were identified： ATP6V1B1（presenting with renal tubular acidosis，nephrocalcinosis，and hypocitraturia）， WFS1（presenting with renal malrotation，hydronephrosis，and stones without metabolic abnormalities）， SLC12A1（presenting with Bartter syndrome type 1，chronic renal insufficiency，hypercalciuria，hypocitraturia，alkalosis，and hyperaldosteronism），and SLC3A1（presenting with bilateral renal stones and cystinuria）. Conclusions:WES is crucial in identifying the underlying etiology of urolithiasis and can guide targeted treatment. We recommend early WES for patients with an initial stone presentation before age 25，those with nephrocalcinosis，or those with abnormal metabolic workups to facilitate precise diagnosis and preventive care.

To analyze the current state and issues of ideological education for graduate students of general practice, from April 10 to Dec 19, 2024, a literature review was conducted on publications from Jan 1, 2001, to Dec 19, 2024, in the CNKI, Wanfang, and VIP databases to identify research entry points. Purposive sampling was used to select postgraduate students majoring in general practice at Guangzhou Medical University and their corresponding faculty as the study participants. A semi-structured in-depth interview method was employed to investigate the current state of ideological and political education. Faculty evaluations of students and their recommendations for ideological and political education were also considered. Thematic framework analysis was applied to the interview data for categorization, integration, and theme extraction. The literature review revealed that enhancing professional identity can strengthen career commitment, leading to the design of an ideological and political education interview outline focused on professional belief and professional identity. The study included 13 general practice postgraduates (mean age: 24.5±1.4 years), of whom 8 were directional students and 5 were non-directional students. Additionally, 7 general practice faculty members were included (mean age: 41.3±5.4 years), with an average of 16.3±5.6 years of experience in general practice education. Five themes were extracted from the interviews: the necessity of ideological and political education, the relationship between professional belief and its educational effects, the intrinsic motivation of ideological beliefs, the influence of external factors on beliefs, and effective approaches to ideological and political education. The study also identified current issues in ideological and political education for general practice postgraduates, including inadequate career planning guidance, reluctance to work in underdeveloped areas, over-reliance on the role modeling of faculty mentors, lack of systematic courses and frameworks for ideological and political education, and limited opportunities for team projects and communication platforms. The current state of ideological and political education for general practice postgraduates reveals deficiencies in career planning support, systematic course construction, practical opportunities, and communication platforms. Education methods remain overly simplistic and are significantly influenced by external factors, underscoring the need for optimization and enhancement.

Purpose: This study examined the diagnostic value of high-frequency ultrasound (HFUS) features in differentiating between benign and malignant skin lesions. Methods: A total of 1,392 patients with 1,422 skin lesions who underwent HFUS examinations were included in an initial dataset (cohort 1) to identify features indicative of malignancy. Qualitative clinical and HFUS characteristics were recorded for all lesions. To determine which HFUS and clinical features were suggestive of malignancy, univariable and multivariable logistic regression analyses were employed. The diagnostic performance of HFUS features combined with clinical information was evaluated. This assessment was validated using internal data (cohort 2) and multicenter external data (cohort 3). Results: Features significantly associated with malignancy included age above 60 years; lesion location in the head, face, and neck or genital regions; changes in macroscopic appearance; crawling or irregular growth pattern; convex or irregular base; punctate hyperechogenicity; blood flow signals; and feeding arteries. The area under the receiver operating characteristic curve, sensitivity, and specificity of HFUS features combined with clinical information were 0.946, 92.5%, and 86.9% in cohort 1; 0.870, 93.1%, and 80.8% in cohort 2 (610 lesions); and 0.864, 86.2%, and 86.6% in cohort 3 (170 lesions), respectively. However, HFUS is not suitable for evaluating lesions less than 0.1 mm in thickness or lesions exhibiting surface hyperkeratosis. Conclusion In a clinical setting, the integration of HFUS with clinical information exhibited good diagnostic performance in differentiating malignant and benign skin lesions. However, its utility was limited in evaluating extremely thin lesions and those exhibiting hyperkeratosis.

Objective:To investigate the application value of antegrade splenic superior region dissection first in laparoscopic total gastrectomy of obesity gastric cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 21 obesity patients with gastric cancer who underwent laparoscopic total gastrectomy in Renji Hospital of Shanghai Jiaotong University School of Medicine from July 2018 to October 2023 were collected. There were 16 males and 5 females, aged (58±13)years. All 21 patients underwent laparoscopic total gastrec-tomy with antegrade splenic superior region dissection first. Observation indicators: operation time, volume of intraoperative blood loss, laparotomy conversion, intraoperative splenic hemorrhage or gastric hemorrhage, lymph node dissection, time to postoperative first flatus, time to postoperative initial liquid food intake, duration of postoperative hospital stay, postoperative complication. Measure-ment data with normal distribution were represented as Mean± SD, and count data were expressed as absolute numbers. Results:All 21 patients underwent laparoscopic total gastrectomy success-fully, with the operation time of (283±47)minutes, time for splenogastric ligament and vascular manage-ment of (34±12)minutes, volume of intraoperative blood loss of (143±86)mL, and no laparotomy conversion. There was no intraoperative splenic hemorrhage or gastric haemorrhage. The total number of lymph node dissected in 21 patients was 375, with the number of lymph node dissected as (21±9)per case. Time to postoperative first flatus, time to postoperative initial liquid food intake and duration of postoperative hospital stay in 21 patients were (3.1±0.7)days, (4.0±0.8)days and (10.1±3.0)days, respectively. There were 2 patients with postoperative complications, including 1 case of incision infection and 1 case of lung infection. The 2 patients with postoperative com-plications were recovered and discharged after conservative treatment. There was no death during the postoperative 30 days.Conclusion:The application of antegrade splenic superior region dissec-tion first in laparoscopic total gastrectomy is safe and feasible, which can reduce surgical difficulty.

Objective To analyze the incidence and disease burden of substance use disorder(SUD)in China from 1990 to 2019,to evaluate the impact of different ages,periods and birth cohorts on the disease burden of SUD,and to predict disease burden of SUD from 2020 to 2034,so as to provide strategies for the prevention of SUD.Methods Based on the Global Burden of Disease Study 2019(GBD 2019)database,the disease burden was described by incidence,years of life lost(YLLs),years lived with disability(YLDs)and disability-adjusted life years(DALYs).The Joinpoint regression model was used to analyze the trend of standardized incidence and standardized DALYs rate of SUD.Based on the age-period-cohort model,the age,period and cohort effects of SUD were discussed.The grey prediction model GM(1,1)was used to fit the trend of the incidence and standardized incidence of SUD and the trend of disease burden,and to predict the incidence and disease burden of SUD in 2020-2034.Results From 1990 to 2019,the standardized incidence of SUD of amphetamines[average annual percentage change(AAPC)=-0.9％]and cocaine(AAPC=-0.5％)in China showed a downward trend(P＜0.001),and the standardized incidence of SUD of cannabis(AAPC=0.9％)showed an increasing trend year by year(P＜0.001).The trend of standardized incidence of opioid abuse disorders was not obvious(P＞0.05).The DALYs rate caused by the 4 SUD showed a decreasing trend year by year(AAPCamphetamines=-2.2％,AAPCcocaine=-1.5％,AAPCcannabis=-1.0％,AAPCopioids=-1.0％,P＜0.001).The results of age-period-cohort effect showed that the peak incidence of amphetamine,cocaine,cannabis and opioid use disorders was in the 25-30 age group.The DALYs rate caused by cannabis SUD increased with age,while the DALYs rates of amphetamines,cocaine and opioids SUD reached the peak in the 25-29,30-34 and 35-39 age groups,respectively.The results of period effect showed that the risk of SUD in propylamines,cocaine and cannabis decreased first and then increased,while the risk of SUD in opioids increased and then decreased and increased again.The results of birth cohort effect showed that the risk of SUD of amphetamines,cocaine and opioids showed a decreasing trend as a whole except for a small fluctuation in individual birth cohorts.The risk of DALYs rate caused by SUD of amphetamines,cocaine and opioids showed a decreasing trend as a whole,while the risk of DALYs rate caused by SUD of cannabis showed an increasing trend year by year.The prediction results showed that the incidence of SUD of amphetamines,cocaine and opioids showed a downward trend from 2020 to 2034,and the incidence of SUD of cannabis showed a fluctuating upward trend.The DALYs attributed to SUD of amphetamines,cocaine,cannabis and opioids showed a decreasing trend year by year.Conclusion The disease burden of SUD in China is decreasing year by year in the future.The incidence and disease burden are affected by age effect,period effect and cohort effect to varying degrees.Early prevention and effective intervention are the key measures to control SUD.
