Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m². Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

Patients with gastric cancer undergoing postoperative chemotherapy often develop myelosuppression due to direct injury to the spleen and stomach caused by surgery， depletion of healthy qi by chemotherapy， impaired generation of ying （荣） qi due to spleen and stomach deficiency， and the accumulation of drug toxicity， which prevents ying qi from reaching and nourishing the bone marrow. Consequently， the bone marrow loses its nourishment and becomes unable to generate blood， leading to myelosuppression. This paper proposes that the core pathogenesis involves failure of the middle jiao （焦） pivot function， dysfunction of ying qi circulation， and insufficient nourishment of essence and marrow. Accordingly， Shengxian Decoction （升陷汤） combined with Danggui Buxue Decoction （当归补血汤） is used as the principal prescription to tonify the middle jiao and uplift center qi， thereby remedying the fundamental insufficiency of ying qi. Modified Compound Danshen Decoction （复方丹参饮） is applied to promote qi circulation， resolve stasis， remove toxin， and unblock collaterals， thereby resolving the obstruction preventing ying qi from reaching the bone marrow. Modified Dabuyuan Decoction （大补元煎） combined with Erzhi Pill （二至丸） is taken as the foundational formula to cultivate the root， replenish marrow， thereby modulating hematopoiesis in bone marrow.

The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

It is believed that the occurrence and development of squamous cell carcinoma （SCC） is closely associated with inflammatory responses. The theory of fire and heat， advocated by LIU Wansu， provides significant clinical guidance for understanding the pathogenesis and treatment of SCC. Based on this theory， the pathological mechanisms and clinical characteristics of SCC at different stages were analyzed. In the precancerous and early stages， the primary pathogenesis is qi stagnation leading to internal generation of constrained heat； in post-surgery， the condition shifts to qi deficiency with latent yin fire； during the treatment phase， the pathogenesis involves accumulation of pathogenic factors， excess toxins， and severe heat toxicity； in the late stage， the main pathology is yin deficiency with toxic heat， and phlegm-stasis obstruction of the internal organs. Corresponding stage-based treatment strategies are proposed. In the early stage， regulating qi movement to dissipate constrained heat； for post-surgery， tonifying qi and raising yang to dispel latent fire； during treatment stage， clearing heat and detoxifying to eliminate cancerous toxins； and in the late stage， nourishing yin and unblocking the bowels to clear deficiency heat.

Objective:To analyze relevant factors influencing severe acute radiation enteritis (SARE) during total neoadjuvant therapy (TNT) for locally advanced rectal cancer (LARC). To identify specific prediction indicators of the occurrence and progression of radiation enteritis by investigating the effect relationships between radiation enteritis and multidimensional factors.Methods:A total of 92 patients with rectal adenocarcinoma who received total neoadjuvant therapy at the First Affiliated Hospital of Soochow University from January 2020 to September 2023 were enrolled in this study. Their relevant information was collected, encompassing clinical nutritional indicators, dynamic changes in hematological parameters, systemic inflammatory indicators, and the occurrence of adverse reactions. Then, risk factors associated with radiation enteritis were determined using logistic regression analysis. Based on independent risk factors, a nomogram model for risk prediction was constructed.Results:Univariate analysis revealed significant correlations of the SARE occurrence with certain nutritional indicators, local tumor measurement data, and laboratory parameters. Multivariate regression analysis further identified the independent risk factors for SARE occurrence, including albumin reduction >26.5% before vs. after treatment ( OR = 5.010, 95% CI: 1.766-14.154, P = 0.010), rectual tenesmus rating of Grade 1-3 ( OR = 3.639, 95% CI: 1.425-9.300, P = 0.024), and elevated disease activity index (DAI) score ( OR ≈ 7.683 per 1-point increase, 95% CI: 1.105-53.410, P = 0.039). The prediction model constructed based on these factors demonstrated high prediction efficiency (AUC = 0.841; 95% CI: 0.749-0.934). Conclusions:The nomogram model constructed using albumin reduction, rectal tenesmus rating, and DAI score can provide accurate, simple, and low-cost risk prediction of radiation enteritis during TNT for LARC patients. This model facilitates the early clinical identification of high-risk patients, providing a basis for implementing personalized adjustments to radiotherapy regimens and enhancing nutritional interventions.

Under the current situation of "low prevalence and low infection" of schistosomiasis in China, and to provide a basis for achieving the goal of eliminating schistosomiasis by 2030 proposed by the Healthy China Action (2019 - 2030) as scheduled, the Hunan Provincial Corps Hospital of the Chinese People's Armed Police Force established a schistosomiasis monitoring and early warning index system based on the previous studies on schistosomiasis early warning index system and the recent literature analysis, combined with the current potential risk factors affecting the transmission and prevalence of schistosomiasis, and organized two rounds of expert consultation and carried out project promotion meetings. The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

[Purpose]To analyze the incidence and changing trends of elderly breast cancer(de-fined as diagnosis at age ≥ 60 years old)in China and globally from 1990 to 2021,and to predict its trends from 2022 to 2035.[Methods]Data on the number of new cases and crude incidence rate of elderly breast cancer in China and globally were extracted from the 2021 Global Burden of Disease Study(GBD)database.The age-standardized incidence rate(ASIR)was calculated by sex and age group.The Joinpoint regression model was used to calculate the annual percentage change(APC)and average annual percentage change(AAPC),to describe the incidence trend of elderly breast cancer from 1990 to 2021.The Bayesian age-period-cohort(BAPC)model was applied to predict the incidence of elderly breast cancer from 2022 to 2035.[Results]From 1990 to 2021,the number of new breast cancer cases among elderly individuals globally increased from 416 444 to 1 023 776,while in China,the number rose from 26 371 to 158 085.The ASIR increased from 89.04/105 to 94.73/105 globally and from 27.24/105 to 58.40/105 in China.By sex,the ASIR of el-derly females increased from 155.19/105 to 170.54/105 globally and from 49.13/105 to 106.00/105 in China;the ASIR of elderly males increased from 2.78/105 to 4.72/105 globally and from 1.69/105 to 6.81/105 in China.By age group,from 1990 to 2021,the incidence rates of breast cancer in elderly female and male both peaked in the age group of 85～89 years old globally.In China,the most significant increases in incidence rates were observed in the age group of 60～64 years old for elderly females and the age group of 70～74 years old for elderly males;these two age groups had the highest incidence rates in their respective sexes in 2021.Joinpoint analysis showed that the ASIR of elderly breast cancer in China presented a continuous upward trend from 1990 to 2021(AAPC=2.51％),with the fastest growth during 2016-2019(APC=5.14％).The global ASIR showed only a slight fluctuating upward trend(AAPC=0.20％),with significant increases only during 1990-1995 and 2003-2010.Predictions from the BAPC model indicated that by 2035,the global ASIR of elderly breast cancer would reach 107.84/105(192.26/105 for females and 6.02/105 for males),while the ASIR in China would reach 104.35/105(188.08/105 for females and 13.32/105 for males).[Conclusion]From 1990 to 2021,the incidence of elderly breast cancer showed an upward trend both in China and globally,with a particularly pronounced increase in elderly male.The disease burden of elderly breast cancer in China is expected to continue increasing in the future,necessi-tating strengthened primary and secondary prevention measures,as well as optimized screening programs for the elderly population to reduce disease risks and improve prognosis.

Objective:To investigate the characteristics of weight gain in the mid and late pregnancy of women with early pregnancy weight loss, and the relationship between weight gain and weight gain rate before the diagnosis of gestational diabetes mellitus (GDM) and GDM.Methods:A retrospective study was conducted on 2 614 singleton pregnant women who underwent prenatal care and delivered at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from January 2014 to December 2021, and whose weight decreased compared to pre-pregnancy weight by 16 weeks of gestation. The rate of weight gain in mid and late pregnancy, also weight gain and weight gain rate at each stage were analyzed. Multivariate logistic regression was used to analyze the impact of total weight gain and weight gain rate at each stage before the diagnosis of GDM on the risk of GDM.Results:The rates of weight gain in mid and late pregnancy for women with early pregnancy weight loss who were underweight, normal weight, overweight, and obese before pregnancy were (0.60±0.15), (0.59±0.18), (0.53±0.20), and (0.42±0.20) kg/week, respectively, all higher than the "Chinese Recommended Standards for Weight Gain During Pregnancy" [which are (0.37-0.56), (0.26-0.48), (0.22-0.37), and (0.15-0.30) kg/week, respectively]. The weight gain rates at each stage of mid and late pregnancy in women with early pregnancy weight loss showed a "bimodal" trend, with the first peak in weight gain rate occurring at 16-20 or 20-24 weeks of gestation [weight gain rates for underweight, normal weight, overweight, and obese women before pregnancy were 0.75 kg/week (0.44-1.00 kg/week), 0.74 kg/week (0.50-1.00 kg/week), 0.63 kg/week (0.39-0.86 kg/week), and 0.50 kg/week (0.25-0.74 kg/week), respectively] and the second peak occurring at 28-32 weeks [weight gain rates for underweight, normal weight, overweight, and obese women before pregnancy were 0.63 kg/week (0.50-1.00 kg/week), 0.63 kg/week (0.38- 0.88 kg/week), 0.60 kg/week (0.25-0.88 kg/week), and 0.50 kg/week (0.22-0.75 kg/week). As of 28 weeks and 36 weeks of gestation, 53.7% (1 404/2 614) and 77.4% (1 946/2 512) of pregnant women, respectively, reached the lower limit of the recommended weight gain for the corresponding gestational weeks. No association was found between insufficient weight gain ( aOR=0.828, 95% CI: 0.639-1.071, P=0.151) or excessive weight gain ( aOR=0.936, 95% CI: 0.598-1.465, P=0.773) before the diagnosis of GDM and the risk of GDM. However, obese women with a weight loss greater than 5% of their pre-pregnancy weight in early pregnancy and a rapid weight gain rate (> P 75) between 16-20 weeks of gestation had an increased risk of developing GDM ( aOR=32.870, 95% CI: 1.625-664.775, P=0.023). Conclusions:In clinical practice, dynamic monitoring of weight changes at various stages of pregnancy in women who lose weight in early pregnancy is recommended. Targeted weight management during mid-pregnancy for women who are obese before pregnancy and experience significant weight loss in early pregnancy may help prevent excessive gestational weight gain and decrease the risk of GDM.

Morphea alopecia is a rare secondary cicatricial alopecia, often caused by linear scleroderma of the scalp. When hair loss appears as the only symptom of morphea, it is easily confused with other localized alopecia. The diagnosis of morphea alopecia depends on histopathologic and dermoscopic examinations. In order to improve the understanding of morphea alopecia among clinicians, this review summarizes research progress in its pathogenesis, clinical and pathological characteristics, diagnosis and treatment.
