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.

This guideline, presented in three parts, details the core aspects of endoscopic/robotic breast surgery, including its techniques, equipment, surgical procedures, perioperative management, complication treatment, long-term follow-up, and outcomes. Part one offered a comprehensive overview of indications for endoscopic and robotic breast surgery, intraoperative techniques, surgical instrument choices, and common endoscopic and robotic breast reconstruction procedures. This part will cover other endoscopic breast procedures beyond immediate breast reconstruction and include perioperative management strategies, to provide healthcare professionals involved in endoscopic and robotic breast surgery with systematic operational guidelines and clinical decision-making references.

ObjectiveTo investigate the effects of Chaihu Jia Longgu Mulitang（CJLM） on depression-like behaviors and neuroinflammation in rats subjected to social isolation combined with chronic unpredictable mild stress（CUMS）， and to explore the potential underlying mechanisms. MethodsSixty male SD rats were randomly divided into a normal group， a model group， and low-， medium-， and high-dose CJLM groups（2.89， 5.78， 11.56 g·kg^-1）， as well as a fluoxetine group（10 mg·kg^-1）. Except for the normal group， all other groups were subjected to social isolation combined with CUMS for 63 d. During the first 35 d， depression models were established only， and from day 36 onward， modeling and drug administration were conducted simultaneously for a total intervention period of 28 d. Depression-like behaviors were evaluated using the sucrose preference test， open-field test， and forced swimming test. Hematoxylin-eosin（HE） staining was performed to observe hippocampal histomorphology. Immunohistochemistry（IHC） was used to detect the expression levels of ionized calcium-binding adapter molecule 1（Iba1） and gasdermin D（GSDMD） proteins in the hippocampus. Western blot analysis was employed to determine the protein expression levels of adenosine 5′-monophosphate（AMP）-activated protein kinase（AMPK） and phosphorylated（p）-AMPK， silent information regulator 1（SIRT1）， nuclear factor-κB（NF-κB） and p-NF-κB， NOD-like receptor protein 3（NLRP3）， and Caspase-1 in the hippocampus. Real-time quantitative polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-6， and IL-1β in the hippocampus. ResultsCompared with the normal group， the model group showed a decreased sucrose preference rate（P<0.01）， reduced total movement distance（P<0.01）， prolonged immobility time（P<0.01）， and decreased central zone residence time（P<0.01） in the open-field test， and increased immobility time in the forced swimming test（P<0.01）. Hippocampal neuronal structure was damaged. The contents of Iba1 and GSDMD in the hippocampus were significantly increased（P<0.01）. The protein expression levels of p-AMPK and SIRT1 in the hippocampus were significantly decreased（P<0.01）， whereas the protein expression levels of p-NF-κB， NLRP3， and Caspase-1 were significantly increased（P<0.01）. The mRNA expression levels of IL-1β， IL-6， and TNF-α in the hippocampus were significantly upregulated（P<0.01）. Compared with the model group， the low-， medium-， and high-dose CJLM groups and the fluoxetine group all were able to reverse depression-like behavioral changes， as evidenced by increased sucrose preference rate， increased total movement distance with shortened immobility time in the open-field test， prolonged central zone residence time， and reduced immobility time in the forced swimming test（P<0.05， P<0.01）. Meanwhile， hippocampal neuronal structural damage was alleviated. In the hippocampus， the expression levels of Iba1 and GSDMD were downregulated， the expression levels of p-AMPK and SIRT1 were upregulated， and the abnormal elevations of p-NF-κB， NLRP3， Caspase-1， as well as IL-1β， IL-6， and TNF-α mRNA were suppressed（P<0.05， P<0.01）. ConclusionCJLM can ameliorate depression-like behaviors in rats subjected to social isolation combined with CUMS and attenuate hippocampal neuroinflammation and pyroptosis， suggesting that its effects may be associated with the regulation of AMPK/SIRT1/NF-κB/NLRP3 signaling pathway.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To investigate the neuroprotective effects of ginsenoside Rb1 in neonatal mice with Hypoxic Ischemia(HI)and analyze its potential molecular mechanisms.Methods:Seven-day-old C57BL/6 neonatal mice were randomly assigned to three groups:Sham group,hypoxic-ischemic(HI)model group,and HI model+ginsenoside Rb1 intervention group(HI+Rb1),with 10 mice per group.The modified Rice-Vannucci method was used to establish the HI model,and ginsenoside Rb1(20 mg/kg)was administered via intraperitoneal injection for 7 consecutive days post-surgery(once per day).Brain damage was assessed on days 7 and 14 post-surgery by evaluating cortical neurons and glial cell numbers,as well as the activation status of the ERK signaling pathway.Additionally,in utero electroporation(IUE)was used to overexpress the ERK signaling pathway in the cortical neurons,and the impact of ERK activation on glial cell development was observed.Further,IUE was used to overexpress ERK in the cortex of P0 neonatal mice,fol-lowed by the HI model on day 7 to analyze the effects of enhanced ERK signaling on oligodendrocyte development and myelin regeneration.Results:Compared to the HI group,the HI+Rb1 intervention group showed significant improve-ment in motor ability,reduction in brain injury area,less mature neuron loss,and increased newborn neurons.Addi-tionally,the number of oligodendrocytes in the cortex was increased,and the activation of the ERK signaling pathway was enhanced.In mice with overexpression of the ERK signaling pathway in the cortex,there was a significant increase in oligodendrocytes.In the HI model with ERK overexpression,an increased number of oligodendrocyte precursor cells were found around the brain injury area,consistent with the results of ginsenoside Rb1 intervention.Conclusion:Gin-senoside Rb1 exerts neuroprotective effects in neonatal mice with hypoxic-ischemic brain injury,potentially through the enhancement of ERK signaling,promoting oligodendrocyte proliferation and myelin regeneration.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To analyze the risk factors of fluconazole resistance in Candida tropicalis(C.tropicalis)urinary tract infection(UTI),and evaluate the efficacy of different treatment regimens.Methods Patients with C.tropicalis UTI at Xiangya Hospital of Central South University from January 2021 to December 2023 were in-cluded for single center retrospective study.The minimum inhibitory concentration(MIC)of fluconazole was deter-mined by microbroth dilution.Patients were divided into a fluconazole-resistant group and a fluconazole-sensitive group based on fluconazole resistance.Risk factors for fluconazole resistance were analyzed based on clinical data,and therapeutic efficacy in patients in fluconazole-resistant group was analyzed.Results A total of 198 patients were included in the study.133(67.2％)C.tropicalis strains were detected to be sensitive to fluconazole,while 65(32.8％)strains were resistant,and 63.1％(n=41)had MIC values ≥128 μg/mL.Compared with fluconazole-sensitive group,fluconazole-resistant group had a higher proportion of pulmonary infection(P=0.019).Pulmonary infection(OR=3.282)was a risk factor for fluconazole resistance in C.tropicalis UTI,while urinary system ob-struction(OR=0.269)was a protective factor for fluconazole resistance in C.tropicalis UTI.There was no statis-tically significant difference in the usage rate of different antimicrobial agent types between the two groups(all P＞0.05).The therapeutic efficacy analysis showed that the effective rates of treatment with fluconazole dosage regi-mens of ≤200 mg/d,≥400 mg/d,and fluconazole monotherapy against fluconazole-resistant strains were 66.7％(6/9),83.3％(5/6),and 100％(6/6),respectively.For patients treated with monotherapy using other drugs or with multidrug sequential treatment regimens,the treatment effective rate was 60.0％(3/5).The proportion of pa-tients in the effective treatment group who removed their urinary catheters after detecting C.tropicalis was higher than that in the ineffective treatment group(P＜0.001).Conclusion The fluconazole resistance of C.tropicalis is related to urinary tract obstruction and concurrent pulmonary infection.When treating UTI caused by fluconazole-resistant strains,the catheter should be removed as early as possible.In addition to increasing the dosage of flucon-azole,other antifungal drugs such as flucytosine alone or sequential treatment with multiple drugs can also be con-sidered.

Objective:To explore the relationship between impulsivity traits,anxiety,and symptoms of eating disorders,with a focus on the mediating effect of anxiety between impulsivity and eating disorder symptoms.Me-thods:A total of 244 patients with eating disorders meeting the DSM-5 diagnostic criteria for anorexia nervosa(AN)and bulimia nervosa(BN)were enrolled,and the Eating Disorder Inventory-1(EDI-1),Barratt Impulsive-ness Scale(BIS-11),and the State Anxiety Inventory(SAI)were assessed.Mediation role analysis was performed by SPSS macro PROCESS program.Results:There was a significant positive correlation between the total score of BIS-11,SAI and EDI-1 in AN and BN patients(AN,r=0.56,0.63,0.72;P＜0.001.BN,r=0.51,0.31,0.56;P＜0.001 or P＜0.01).The total score of SAI played a mediating effect between the total score of BIS-11 and the total score of EDI-1,but the total score of SAI played a partial mediating effect(effect ratio was 46.9％)in patients with AN,and the total score of SAI played a full mediating effect in patients with BN.Conclusion:Impulsive trait and anxiety may be positive predictors of eating disorder symptoms.Anxiety mediates the relationship between impul-sivity trait and eating disorder symptoms,with a partial mediating effect in patients with AN and a full mediating effect in patients with BN.
