This paper summarizes Professor LIU Shangyi's clinical experience in treating acute mastitis based on the "membrane collaterals" theory. It is considered that constraint and stagnation of the membrane collaterrals is the primary pathogenic factor， with damp， heat， phlegm， and stasis being the secondary manifestations. If untreated， the condition can progress to heat toxin injuring the membrane. In treatment， the emphasis is diffusing and unblocking membrane collaterals， unblocking breast and relieving constraint. The clinical course of the disease can be divided into three stages including the early stage with mild constraint heat， the middle stage with escalating toxic heat， and the later stage with a decline of pathogens but deficiency of healthy qi. In correspondence， self-made Tongru Formula （通乳方） for diffusing membrane and venting constraint， self-made Toumo Jiedu Formula （透膜解毒方） for unblocking membrane and relieving toxin， and Tuoli Xiaodu Powder （托里消毒散） with modifications for restoring membrane and rectifying healthy qi should be used， respectively.

Despite of the widespread use of hydrogen and methane breath test, the variability in testing protocols, gas measurement techniques, and interpretation criteria continues to challenge the reproducibility and comparability across centers, especially in the Asia-Pacific region. The Asian Neurogastroenterology and Motility Association hence presents the first Asian monograph guiding application and interpretation of breath test. The monograph was formulated according to the framework of indications, preparatory process, performance, and interpretation of results, as well as future direction for research.

Objective: To analyze the etiologic distribution of difficult crossmatching and the characteristics of red blood cell antibodies, to summarize compatible transfusion strategies based on serological abnormalities, and to evaluate red blood cell transfusion efficacy and changes in bilirubin levels before and after transfusion. Methods: A retrospective analysis was conducted on difficult crossmatching cases handled by the Department of Blood Transfusion of our hospital from January 2024 to December 2025. Cases that met the criteria for difficult crossmatching determination and had complete data were included in the analysis of the causes and antibody distribution. Patients who completed red blood cell transfusion and had complete hemoglobin (Hb) data before and within 24 hours after transfusion were included in the exploratory subgroup analysis of transfusion efficacy; among them, those who also had total bilirubin and indirect bilirubin data before and after the corresponding transfusion event were included in the bilirubin analysis. According to the main serological abnormal manifestations before transfusion and the actual compatible transfusion management pathways, the cases included in the exploratory subgroup analysis were divided into three groups: the alloantibody-related difficult crossmatching group, the autoantibody-related or autoantibody combined with alloantibody-related difficult crossmatching group, and the ABO blood group identification abnormality-related difficult crossmatching group. The Hb levels before and after transfusion, the Hb increase after transfusion of each unit of red blood cells, and the changes in bilirubin levels before and after transfusion were compared among the groups. Results: A total of 322 difficult crossmatching cases met the predefined criteria, of which 287 were included in the analysis of causes and antibody distribution. There were 183 cases of alloantibody-related difficult crossmatching (63.76%), 54 cases related to inconsistency between ABO forward and reverse typing (18.82%), 44 cases related to autoantibodies (15.33%), and 6 cases related to interference from anti-CD38 monoclonal antibody drugs (2.09%). Among the 183 alloantibody-related cases, 79 cases had only a single alloantibody detected, among which antibodies of the Rh blood group system accounted for 49.37% (39/79). Among single alloantibodies, anti-E was detected most frequently, with 35 cases (44.30%), followed by anti-M with 19 cases (24.05%) and anti-Le with 13 cases (16.46%). A total of 109 cases were included in the exploratory subgroup analysis of transfusion efficacy, including 76 cases in the alloantibodyrelated difficult crossmatching group, 17 cases in the autoantibody-related or autoantibody combined with alloantibody-related difficult crossmatching group, and 16 cases in the ABO blood group identification abnormality-related difficult crossmatching group. The sex distribution and history of previous transfusion differed between cases included in and not included in this analysis. The Hb levels after transfusion in all three groups were higher than those before transfusion, and the differences were statistically significant (P<0.05). The Hb increase per unit of red blood cells did not differ significantly among the three groups (P=0.086). Among 73 cases with paired total and indirect bilirubin data corresponding to the transfusion events, the comparison of changes in total bilirubin among the three groups showed no statistically significant difference (P=0.864), and the comparison of changes in indirect bilirubin among the three groups also showed no statistically significant difference (P=0.914). Conclusion: Alloantibody-related factors were the main causes of difficult crossmatching in this study. Among single alloantibodies, Rh blood group system antibodies, especially anti-E, were relatively common. In the included exploratory subgroup, after individualized compatible transfusion based on the causes of difficult crossmatching, antibody specificities, and crossmatching results, Hb levels were higher after transfusion than before transfusion in all three groups. Within the scope of this study, the magnitude of bilirubin changes did not differ significantly among the different types of difficult crossmatching.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

[Purpose]To analyze cancer incidence and mortality in Xinjiang cancer registration ar-eas in 2020 and the trends from 2016 to 2020.[Methods]Incidence and mortality data of cancer reported by four cancer registration areas in Xinjiang in 2020 were collected.Crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW),and cumulative rate(0～74 years old)were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint regression was applied to ana-lyze the trends of incidence and mortality from 2016 to 2020,and the average annual percentage change(AAPC)was calculated.[Results]In 2020,the crude incidence rate of cancer in Xinjiang cancer registration areas was 291.67/105(286.64/105 for male,296.64/105 for female),ASIRC and ASIRW were 190.43/105 and 206.58/105,and the cumulative incidence rate(0～74 years old)was 20.51％.The crude mortality rate was 185.58/105(2 1 8.79/105 for male,152.78/105 for female),ASMRC and ASMRW were 109.13/105 and 126.64/105,and the cumulative mortality rate(0～74 years old)was 11.54％.In 2020,the incidence and mortality rates increased with age,peaking in the age groups of 80～84 and ≥85 years old,respectively.Lung cancer was the leading cause of incidence(crude incidence rate:51.13/10s),followed by female breast cancer,thyroid cancer,colorectal cancer and stomach cancer.Lung cancer was also the leading cause of mortality(crude mortality rate:41.14/105),followed by liver cancer,colorectal cancer,stomach cancer and fe-male breast cancer.There was no significant change in the ASIRC/ASMRC from 2016 to 2020(incidence AAPC=2.95％,mortality AAPC=8.51％,both P＞0.05).[Conclusion]The incidence and mortality of cancer in Xinjiang cancer registration areas were stable from 2016 to 2020.Lung cancer,digestive system cancers(colorectal,gastric,liver cancers),and female breast cancer re-main the main cancers threatening the health of Xinjiang residents,indicating the need to strengthen screening and early diagnosis and treatment.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G＞T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

Extensive studies have identified potential adverse effects on semen quality of obesity, based on body mass index, but the association between body fat distribution, a more relevant indicator for obesity, and semen quality remains less clear. We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017-2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 10 6 (0.09 × 10 6 -0.27 × 10 6 ) ml and 12.21 × 10 6 (4.52 × 10 6 -19.91 × 10 6 ) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.

Objective:To construct a predictive model of ≥ grade 2 radiation esophagitis (RE) in patients with esophageal cancer during concurrent radiochemotherapy (CRT) based on machine learning (ML) algorithm.Methods:A retrospective analysis was conducted on the clinical data of 276 patients with esophageal cancer who had received CRT at Lu'an Hospital of Anhui Medical University from January 2018 to January 2023. The occurrence of RE was evaluated according to grading criteria of RE developed by American Radiation Therapy Oncology Group, with ≥ grade 2 RE as the outcome event. After screening variables through the least absolute shrinkage and selection operator (LASSO) regression, the dataset was re-established. The dataset was then divided into training set ( n=193) and testing set ( n=83) in a 7∶3 ratio and included in four ML models: random forest (RF) , decision tree (DT) , extreme gradient boosting (XGBoost) , and support vector machine (SVM) . In the models, data training and model optimization were conducted in the training set, and model performance was evaluated in the testing set using the receiver operator characteristic (ROC) curve. The area under the curve (AUC) , accuracy, precision, sensitivity, and F1 score were calculated to assess the model. SHAP analysis was used to explain the optimal model. Results:By the end of follow-up, 91 cases (32.97%) of esophageal cancer patients had experienced ≥ grade 2 RE during CRT. There were statistically significant differences in tumor lesion length ( Z=-5.53, P<0.001) , Karnofsky performance status (KPS) score ( χ2=5.92, P=0.015) , the Eastern Cooperative Oncology Group (ECOG) score ( χ2=4.01, P=0.045) , hypertension ( χ2=15.35, P<0.001) , diabetes ( χ2=13.06, P<0.001) , white blood cell count ( Z=-6.59, P<0.001) , neutrophil count ( Z=-6.72, P<0.001) , and radiotherapy dose ( χ2=9.81, P=0.002) between ≥ grade 2 RE occurrence group ( n=91) and no occurrence group ( n=185) . After LASSO regression screening, 7 characteristic variables were ultimately selected, which were tumor lesion length, ECOG score, KPS score, neutrophil count, hypertension, diabetes, and radiotherapy dose. ROC curve analysis showed that the XGBoost model had better predictive performance, with an AUC of 0.90, accuracy of 0.82, precision of 0.80, sensitivity of 0.73, and F1 score of 0.76. The AUC, accuracy, precision, sensitivity, and F1 score of RF model were 0.89, 0.78, 0.76, 0.48, and 0.59, respectively. The AUC, accuracy, precision, sensitivity, and F1 score of DT model were 0.72, 0.72, 0.44, 0.60, and 0.52, respectively. The AUC of SVM model was 0.74, with an accuracy of 0.82, precision of 0.52, sensitivity of 0.88, and F1 score of 0.65. The XGBoost model was explained using SHAP analysis, which indicated that the tumor lesion length, neutrophil count, hypertension, diabetes, and radiotherapy dose had a strong predictive ability for the occurrence of ≥ grade 2 RE during CRT in esophageal cancer patients. Conclusions:The model established based on the XGBoost method has good predictive performance for the occurrence of ≥ grade 2 RE in esophageal cancer patients during CRT. Meanwhile, combined with SHAP analysis, it can provide an intuitive understanding of the impact of important features in the model on the outcome.

Objective To explore the effects of Jingling Oral Liquid(mainly composed of Polygoni Multiflori Radix,Polygonati Rhizoma,Platycladi Semen,Nelumbinis Semen,Ligustri Lucidi Fructus,Poria,and Lilii Bulbus)as an adjunctive therapy on cognitive,motor,and social abilities in children with global developmental delay(GDD).Methods A total of 120 children with GDD who visited the Department of Neurological Rehabilitation at Hebei Children's Hospital from July 2021 to November 2023 were selected as the study subjects.The children were randomly divided into a control group and a trial group using a random number table,with 60 children in each group.The control group received conventional comprehensive rehabilitation training,while the trial group received Jingling Oral Liquid as an adjunctive therapy in addition to the control group's treatment.The treatment course lasted 12 weeks.Before and after treatment,the changes in Gesell Developmental Scale(GDS)scores,Peabody Developmental Motor Scales(PDMS)scores,motor function scores,and language ability scores in both groups were observed to evaluate the cognitive,motor,and social abilities of the children.Results(1)After treatment,the scores of all dimensions of the GDS,including adaption,developmental quotient of fine motor,language developmental quotient,and personal-social developmental quotient,were significantly increased in both groups compared to those before treatment(P＜0.01),and the improvement of GDS scores in the trial group was significantly superior to that in the control group(P＜0.01).(2)After treatment,the scores of all dimensions of the PDMS,including fine developmental quotient score,standardized score of visual-motor integration,and standardized score of grasping,were significantly increased in both groups compared to those before treatment(P＜0.01),and the improvement of PDMS scores in the trial group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the scores of motor function indicators of fine motor quotient(FMQ),gross motor quotient(GMQ),and total motor quotient(TMQ)were significantly increased in both groups compared to those before treatment(P＜0.01),and the improvement of motor function scores in the trial group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the language ability scores were significantly increased in both groups compared to those before treatment(P＜0.01),and the improvement of language ability scores in the trial group was significantly superior to that in the control group(P＜0.01).Conclusion The combination of Jingling Oral Liquid with conventional comprehensive rehabilitation training can effectively improve the cognitive,motor,and social abilities of children with GDD.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.
