Recent research from the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) indicates that breast cancer is the most prevalent malignant tumor among women, posing a significant threat to women's health. Surgery remains the primary therapeutic modality for breast cancer. Recently, endoscopic and robotic breast surgical techniques have gained acceptance among both surgeons and patients. However, considerable variation exists in surgical approaches and outcomes. To standardize these techniques, facilitate their broader clinical adoption, and ultimately improve patient care, the Endoscopic-robotic Breast Surgery Clinical Trials Consortium (ErBSCTC) of China has developed this guideline. This document encompasses the technologies and instrumentation utilized in endoscopic and robotic breast surgery, surgical techniques, perioperative management, complication handling, long-term follow-up, and oncologic outcomes, aiming to provide evidence-based guidance for healthcare professionals involved in the prevention, diagnosis, and treatment of breast diseases.

Breast cancer is the most common malignant tumor among women in China, with surgery being one of the primary treatment modalities. Endoscopic/robotic breast surgery (ErBS) is gaining widespread acceptance among patients and surgeons alike due to its advantages of minimal invasiveness, superior cosmetic outcomes, and accelerated recovery. However, substantial heterogeneity currently exists across China regarding patient selection, standardized operative techniques, perioperative management, and complication handling, underscoring the urgent need for evidence-based consensus guidelines. To promote standardization and ensure consistent quality of ErBS, the Chinese Endoscopic-Robotic Breast Surgery Clinical Trials Consortium (CErBSCTC) has systematically reviewed the latest high-quality evidence and formulated the "Protocol for China Endoscopic and Robotic Breast Surgery Guidelines (2026 edition)", which outlines a comprehensive methodology for guideline development.

Objective: To investigate the clinical characteristics, the types of unexpected antibodies, and their impacts on immunological risks among patients with different frequencies of cross-matching incompatibility, so as to propose corresponding solutions. Methods: Data of cross-matching incompatibility samples from 92 medical institutions during 2022 to 2024 were collected and divided into three groups based on the frequency of cross-matching. Statistical analysis was performed on disease types, distribution of hematologic diseases, alloantibody detection rates, and proportions of alloantibody types. Results: The 858 patients were divided into three groups based on the frequency of blood cross-matching incompatibility: ≥5 times (8.28%, 71/858), 2 to 4 times (28.21%, 242/858); 1 time (63.52%, 545/858). There was a clustered distribution of disease types in the ≥5 cross-matchings group, with 71.83% (51/71) of patients having tumors or hematologic and hematopoietic diseases. In contrast, the disease types in the 2 to 4 cross-matchings and 1 cross-matching groups were more diverse. An analysis of 249 patients with hematologic diseases found that multiple myeloma was the most common disease in all three groups, accounting for 31.43% (11/35), 35.37% (29/82), and 37.88% (50/132) respectively. In the ≥5 cross-matchings group, myelodysplastic syndrome (14.29%, 5/35) and thalassemia (14.29%, 5/35) were the second most common diseases. In contrast, in the 2 to 4 cross-matchings group and 1 cross-matching group, autoimmune hemolytic anemia was the second most common disease, with prevalence rates of 20.73% (17/82) and 24.24% (32/132), respectively. Alloantibodies were detected in 54.66% of the patients, with antibodies against Rh blood group being most frequent (>50%) in all three groups. The detection rates of alloantibodies/alloantibodies with coexisting autoantibodies decreased across groups: the ≥5 cross-matchings group (70.42%, 50/71) > the 2 to 4 cross-matchings group (54.96%, 133/242) > the 1 cross-matching group (52.48%, 286/545). Conclusion: The risk of alloantibody production increases in patients with multiple cross-matching incompatibilities, especially in those with tumors or hematologic diseases. For handling of cross-matching incompatibility cases, it is recommended to optimize the cross-matching process, implement individualized transfusion plans, and enhance the technical capabilities of clinical transfusion departments and blood group reference laboratories to ensure the safety and effectiveness of transfusions.

ObjectiveTo investigate the chemical hazards in the production line of lithium batteries, so as to provide a scientific basis for the management of occupational-health risk and to promote the healthy and sustainable development of the lithium battery industry. MethodsAn on-site survey on the process flow of the production of lithium battery was conducted in an enterprise. Volatile organic compounds (VOCs) in the occupational environment were collected by Summa canisters, carbonates and N-methyl pyrrolidone (NMP) were collected using activated carbon tubes, and airborne metals were collected using filter membranes. VOCs, carbonates and NMP were detected by gas chromatography-mass spectrometry (GC-MS), and airborne metal elements in the dust samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). ResultsNon-targeted environmental monitoring results indicated that NMP was detected in the negative /positive electrode coating, assembly and drying filling workstations, dimethyl carbonate (DMC) was detected in the assembly, drying and electrolyte injection workstations, and ethyl methyl carbonate (EMC) was detected solely in the electrolyte injection workstation. Semi-quantitative analyses of VOCs identified 136 pollutants, including acrylonitrile and halohydrocarbons. Quantitative targeted environmental monitoring results revealed the highest geometric mean (GM) concentration of EMC (31.450 mg·m^-3) was found in the assembly and drying workstations, diethyl carbonate (DEC) was detected in all workstations. While vinylene carbonate (VC) and ethylene carbonate (EC) were detected only in electrolyte injection, assembly and drying workstations. NMP was detected in all positive electrode coating samples, with a GM concentration of 5.68 mg·m^-3 (concentration range: 4.0‒ 7.4 mg·m^-³). Lithium was exclusively detected in dust samples from the liquid injection workstation (GM: 0.014 μg·m^-³). ConclusionNMP, EMC, DEC, and other chemicals are identified at the key workstations such as the positive electrode coating, electrolyte injection, assembly and drying in the lithium production line. Furthermore, semi-quantitative VOCs analyses identified 136 pollutants, demonstrating a characteristic of multicomponent chemical exposure.

BACKGROUND:In the initial stage of multiple sclerosis,central immune cells activate and release a large number of inflammatory factors,causing white matter demyelination and even involving gray matter neurons.The equilibrium of differentiation between different subsets of CD4+ T cells plays an important role in the progression of experimental autoimmune encephalomyelitis.The previous results of the research group showed that the active ingredient astragalus glycoprotein in astragalus can regulate the immune response in experimental autoimmune encephalomyelitis mice,and whether it has a regulatory effect on the differentiation of T cell subsets has not been determined. OBJECTIVE:To explore the therapeutic effects and immune regulatory mechanisms of astragaloside IV on experimental autoimmune encephalomyelitis mice. METHODS:Female C57BL/6 mice were divided into the normal control group,experimental autoimmune encephalomyelitis disease model group,and astragaloside IV treatment group(n=8 per group).Myelin oligodendrocyte glycoprotein peptides 35-55 were used for experimental autoimmune encephalomyelitis model induction in the last two groups.On day 10 to 28 after immunization,the astragaloside IV treatment group was treated with 40 mg/kg per day astragaloside IV intragastrically.Body weight and clinical scores of mice in each group were recorded from the immunization day to the 28th day.On the 28th day after immunization,the mouse spinal cord was taken and made into frozen sections for hematoxylin-eosin staining and Lux fast blue staining to observe pathological changes in the spinal cord.Percentage of splenic T cell subsets was detected using flow cytometry.Western blot assay was used to determine the protein expression of interferon-γ,interleukin-17 and interleukin-6 in the spinal cord.Levels of interferon-γ,interleukin-17,interleukin-6 and interleukin-4 in supernatants of cultured splenocytes were determined by ELISA. RESULTS AND CONCLUSION:(1)Compared with the experimental autoimmune encephalomyelitis disease model group,astragaloside IV could reduce the degree of weight loss in experimental autoimmune encephalomyelitis mice(P<0.05),ameliorate clinical symptoms(P<0.05),inhibit the infiltration of inflammatory cells and alleviate myelin loss(P<0.01,P<0.05).(2)Compared with the experimental autoimmune encephalomyelitis disease model group,astragaloside IV could inhibit the proportion of CD4+T cell subsets expressing interferon-γ(P<0.001)and interleukin-17(P<0.001),but increase percentages of CD4+ interleukin-10+(P<0.001)and CD4+ transforming growth factor-β+(P<0.01)T cell subsets.(3)Astragaloside IV could inhibit the expression of interferon-γ(P<0.05,P<0.01),interleukin-17(P<0.05,P<0.05),and interleukin-6(P<0.05,P<0.05)in the spinal cord and spleen,and up-regulate the expression of interleukin-4(P<0.01)in spleen.(4)These findings confirm that astragaloside IV alleviates clinical symptoms in experimental autoimmune encephalomyelitis mice,which may be related to regulating the splenic T cell subsets,therefore,inhibiting the infiltration of inflammatory cells into the center and reducing the demyelination.

Objective:To examine the effects of Zishenwan Prescription on bile acid metabolism in mice with diabetic encephalopathy; To explore its mechanism of improvement of diabetic encephalopathy.Methods:Male C57BL/6J mice were used to replicate the mouse model of type 2 diabetes mellitus by using high-fat chow and a single intraperitoneal injection of streptozotocin (120 mg/kg). The mice were screened for diabetic encephalopathy by using the Morris water maze test after 8 weeks of continuous stimulation with hyperglycemia, and were divided into model group and Zishenwan Prescription group according to random number table method, with 12 mice in each group. The mice in the Zishenwan Prescription group were treated with the crude extract of Zishenwan Prescription (9.36 g/kg) by gavage, and the normal group and the model group were treated with the same volume of distilled water once a day for 8 weeks. At the end of the treatment, Morris water maze test was used to investigate the cognitive function of diabetic encephalopathy mice; cresyl violet staining was used to detect the number of granule neurons in the hippocampus; serum and feces were collected to detect the content of bile acids by liquid-liquid coupling; hepatic bile acid synthase CYP7a1 and CYP27a1, farnesol X receptor (FXR), fibroblast growth factor 15 (FGF15), fibroblast growth factor receptor 4 (FGFR4), and ileocecal apical sodium-dependent bile acid transporter protein (ABST) mRNA levels were detected by using fluorescence quantitative PCR assay.Results:Compared with the model group, mice in the Zishenwan Prescription group had shorter evasion latency time ( P<0.05 or P<0.01), decreased time to first reach the platform ( P<0.01), increased number of times to traverse the platform ( P<0.01), and reduced neuronal cell damage in hippocampal area; mice in the Zishenwan Prescription group showed decreased serum and fecal total bile acid content ( P<0.05 or P<0.01); the liver CYP7a1 and CYP27a1 mRNA expressions increased ( P<0.01), and FXR and FGF15 mRNA expressions decreased ( P<0.01); ileal ABST mRNA expression decreased ( P<0.01). Conclusion:Zishenwan Prescription may regulate bile acid metabolism, inhibit FRX-FGF15/FGFR4 signaling and ABST expression to promote new bile acid synthesis and conjugated bile acid reabsorption, and thus improve cognitive function in diabetic encephalopathy mice.

Objective:To understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.

【Objective】 This study endeavors to introduce the statistical process control (SPC) method to analyze the quality control index concerning red blood cells in additive solution with leukocytes reduced, with the aspiration to advance the effective utilization of blood quality control data, thereby providing empirical foundations for the continual enhancement of blood quality. 【Methods】 Between 2020 and 2022, test data pertaining to the quality control index of red blood cells in additive solution with leukocytes reduced were amassed from six blood stations in Chongqing area. Utilizing Minitab software, the SPC analysis was carried out, p-control charts were delineated, the non-conformance rates of each quality control index along with their 95% confidence intervals were computed, as well as the Process Capability Index (Z value). 【Results】 In accordance with the Whole Blood and Blood Components Quality Requirements, the appraisal of the quality control indexes for red blood cells in additive solution with leukocytes reduced manifested a conformity rate of 100% for appearance, end-of-storage hemolysis rate and sterility test. Nonetheless, the conformity rates for volume, hemoglobin, hematocrit and residual leukocytes did not attain 100%, albeit all were ≥75%. Through the employment of binomial distribution-based p-control charts, the controlled state of the production process was discerned. Although the overarching conformity rate satisfied the national standard stipulations, it was discerned that there were out-of-control points concerning volume, hemoglobin, hematocrit, and residual leukocytes across different institutions, exhibiting palpable trends. The non-conformance rates of all quality control indexes were less than 25%, yet at a 95% confidence level, the residual leukocyte counts from institutions B, C, E, and F did not adhere to the stipulations (exceeding 25%). By architecting the ability evaluation index Z value for count data process capability analysis, it was unveiled that the volume of institution E, the hematocrit of institutions B, C, and F, and the residual leukocytes Z values of all six blood collection and supply institutions were below 2, hinting at avenues for amelioration. 【Conclusion】 The SPC method anchored in binomial distribution exhibits substantial application merit in blood component quality management, facilitating real-time surveillance of blood collection, preparation, and storage procedures.

This article reported a prenatally diagnosed case of complete ring chromosome 15. A 38-year-old woman who conceived by in vitro fertilization and frozen embryo transfer underwent amniocentesis for prenatal diagnosis at 18 +5 weeks of gestation due to advanced maternal age. The result of G-banding karyotyping was mos 46,XX,r(15)[88]/45,X,-15[11]/46,XX,r(15;15)[1]. No numerical abnormalities of chromosomes or definite pathogenic copy number variations (CNVs) were detected by chromosomal microarray analysis. Amniocentesis was performed again at 31 +6 weeks of gestation. The result of genome copy number variation sequencing indicated no pathogenic CNV and fluorescence in situ hybridization on cultured amniocytes revealed nuc ish(15q)×1[15]/(15q)×3[5]/(15q)×2[80]. Based on all the prenatal diagnosis results, it was suggested that the fetus carried a complete ring chromosome 15. As the peripheral blood chromosomes of the couple were normal and no obvious abnormalities were detected by the prenatal ultrasound either in our hospital or another hospital, the pregnant woman decided to continue the pregnancy after genetic counseling and delivered a baby girl at 41 weeks of gestation. The girl showed no physical abnormalities during a seven-month follow-up.

AIM:To investigate the influencing factors of abnormal telangiectasia secondary to diabetic retinopathy(DR).METHODS: Prospective studies. A total of 153 cases(240 eyes)with DR treated in our hospital from January 2021 to January 2023 were selected to analyze the risk factors of abnormal telangiectasia secondary to DR and its predictive efficacy.RESULTS: The patients were divided into dilated group(77 eyes of 40 cases)and non-dilated group(163 eyes of 113 cases)according to whether they had secondary abnormal telangiectasia. There were significant differences in diabetic macular edema, hard exudates grade and fasting blood glucose level between the two groups(P<0.05). Logistic regression analysis showed that diabetic macular edema, high hard exudates grade and high blood glucose level were the risk factors for abnormal telangiectasia secondary to DR(P<0.05).CONCLUSION: The occurrence of telangiectasia secondary to DR may be related to diabetic macular edema, grade 3 hard exudates and high blood glucose level.
