Endometriosis （EMT） is a common disease with frequent occurrence and difficult to be cured in modern clinical practice of obstetrics and gynaecology. It is characterized by progressively worsening dysmenorrhoea， pelvic mass， and infertility. The incidence of EMT is growing and increasingly younger patients are diagnosed with this disease， which poses a serious threat to the reproductive and psychological health of women of childbearing age and adolescent females. However， the pathogenesis of EMT is still not completely clear， and the disease has a long course. Therefore， developing new therapies is an urgent clinical problem to be solved. Great progress has been achieved in the treatment of EMT with traditional Chinese medicine （TCM）， while the underlying mechanism remains in exploration. Programmed cell death （PCD） is a cell death mode mediated by a variety of bio-molecules with specific signaling cascades. The known PCD processes include apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis， which all play a pivotal role in the development of EMT. Researchers have made achievements in the treatment of EMT with TCM， which regulates PCD via multiple pathways， routes， targets， and mechanisms. However， the progress in the regulation of PCD in the treatment of EMT with TCM remains to be reviewed. This paper reviews the research progress in the treatment of EMT with TCM from five PCD processes （apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis）， with the aim of providing a theoretical basis for the clinical prevention and treatment of EMT.

ObjectiveTo understand the epidemiological distribution and gene evolutionary variation of influenza A (H3N2) viruses in Fengxian District, Shanghai, in the surveillance year of 2023, and to provide a reference basis for influenza prevention and control. MethodsThe prevalence of influenza virus in Fengxian District in the 2023 influenza surveillance year (April 2023‒March 2024) was analyzed. The hemagglutinin (HA) gene, neuraminidase (NA) gene, and amino acid sequences of 75 strains of H3N2 influenza viruses were compared with the vaccine reference strain for similarity matching and phylogenetic evolutionary analysis, in addition to an analysis of gene characterization and variation. ResultsIn Fengxian District, there was a mixed epidemic of H3N2 and H1N1 in the spring of 2023, with H3N2 being the predominant subtype in the second half of the year, and Victoria B becoming the predominant subtype in the spring of 2024. A total of 75 influenza strains of H3N2 with HA and NA genes were distributed in the 3C.2a1b.2a.2a.2a.3a.1 and B.4 branches, with overall similarity to the reference strain of the 2024 vaccine higher than that of the reference strain of the 2022 and 2023 vaccine. Compared with the 2023 vaccine reference strain, three antigenic sites and one receptor binding site were changed in HA, with three glycosylation sites reduced and two glycosylation sites added; where as in NA seven antigenic sites and the 222nd resistance site changed with two glycosylation sites reduced. ConclusionThe risk of antigenic variation and drug resistance of H3N2 in this region is high, and it is necessary to strengthen the publicity and education on the 2024 influenza vaccine and long-term monitoring of influenza virus prevalence and variation levels.

Cough variant asthma is a distinct subtype of asthma characterized by chronic irritant dry cough as the sole or predominant clinical manifestation. It is one of the primary causes of chronic cough in children. In traditional Chinese medicine, it belongs to the category of " spasmodic cough", " wind-induced cough", " chronic cough", and " asthmatic cough". At present, Western medicine treatment approaches mainly focus on symptomatic treatment, but fail to fully deal with its complex systemic mechanisms, and have limitations such as poor control of clinical symptoms and rebound exacerbation upon treatment cessation. Based on the theory of " systemic qi stagnation", this paper proposes that the core pathogenesis of cough variant asthma in children is qi stagnation, intermingling of phlegm and blood stasis, and obstruction of collaterals. Disease progression is fundamentally driven by exogenous pathogen activation of endogenous predispositions, particularly dysregulation of sanjiao qi movement, which serves as the primary disease-inducing factor. During the acute phase, the treatment principle focuses on dispelling wind and ventilating lung to restore physiological qi. As the disease progresses to the progressive phase, the focus shifts toward smoothing liver and purging lung to resolve qi counterflow. In the chronic phase, therapeutic strategy prioritizes dissipating phlegm and eliminating blood stasis to smooth collaterals. Finally, during the remission phase, treatment emphasizes strengthening spleen and kidney to consolidate the foundation and cultivate the vitality. This integrative approach synergizes the external elimination of latent pathogens, internal harmonization of qi movement, and dredging collaterals by dispelling blood stasis. It also incorporates the theory of " gentle dispersion to expel pathogens and moistening dryness to harmonize collaterals", aiming to provide a theoretical basis and effective prescriptions for the integrated traditional Chinese and Western medicine treatment of cough variant asthma in children.

Doxorubicin (Dox) is an anthracycline drug widely applied in various malignancies. However, the fatal cardiotoxicity induced by Dox limits its clinical application. Post-transcriptional protein modification via ubiquitination/deubiquitination in cardiomyocytes mediates the pathophysiological process in Dox-induced cardiotoxicity (DIC). In this study, we aimed to clarify the regulatory role and mechanism of a deubiquitinating enzyme, ubiquitin-specific peptidase 13 (USP13), in DIC. RNA-seq analysis and experimental examinations identified that cardiomyocyte-derived USP13 positively correlated with DIC. Mice with cardiac-specific deletion of USP13 were subjected to Dox modeling. Adeno-associated virus serotype 9 (AAV9) carrying cTNT promoter was constructed to overexpress USP13 in mouse heart tissues. Cardiomyocyte-specific knockout of USP13 exacerbated DIC, while its overexpression mitigated DIC in mice. Mechanistically, USP13 deubiquitinates the stimulator of interferon genes (STING) and promotes the autolysosome-related degradation of STING, subsequently alleviating cardiomyocyte inflammation and death. Our study suggests that USP13 serves a cardioprotective role in DIC and indicates USP13 as a potential therapeutic target for DIC treatment.

Objective To evaluate the efficacy of preoperative electroacupuncture intervention in promoting postoperative gastrointestinal functional recovery by meta-analysis.Methods The databases of PubMed,Cochrane Library,Web of Science,Embase,CBM,CNKI,VIP,and WanFang were searched systematically.The search period ranged from the inception of the databases to March 2024.Two researchers screened the literature independently,extracted the data,used Cochrane Risk of Bias tools to evaluate the quality of the inclusion study,and used RevMan 5.3 software for meta-analysis.Results Twelve RCTs were included,with 773 patients.There were 421 patients in the preoperative electroacupuncture group and 352 patients in the control group.The results of the meta-analysis showed that,time to first flatus(SMD=-0.56,95%CI-0.84 to-0.28,P＜0.001),time to first defecation(MD=-6.40 hours,95%CI-9.27 to-3.53,P＜0.001),time to bowel sound recovery(MD=-8.45 hours,95%CI-10.37 to-6.52,P＜0.001),time to first oral feeding(MD=-16.88 hours,95%CI-23.92 to-9.83,P＜0.001),the incidence of PONV(RR=0.75,95%CI 0.57 to 0.98,P=0.04)and length of hospital stay(MD=-0.78 d,95%CI-1.38 to-0.19,P=0.010)were significantly lower than the control group.Conclusion Electroacupuncture intervention before operation can effectively promote the recovery of post-operative exhaust,defecation,and bowel sound,shorten the time of fasting and drinking,reduce the inci-dence of PONV,shorten the length of hospital stay,and has good clinical value in promoting the recovery of postoperative gastrointestinal function.

Purpose To investigate the value of MYB and Notch1 immunohistochemical staining in the differential diagno-sis of classic adenoid cystic carcinoma of the breast(C-AdCC)and solid-basaloid adenoid cystic carcinoma of the breast(SB-AdCC).Methods MYB and Notch1 immunohistochemical staining were performed in 20 cases of C-AdCC,6 cases of SB-AdCC and 65 cases of other breast lesions in the archives of pa-thology department.26 cases of AdCC were detected by FISH,and 6 cases of SB-AdCC were detected by NGS.Results MYB immunohistochemical staining showed that C-AdCC(20/20)was moderately or strongly positive,while SB-AdCC(4/6)was mod-erately or strongly positive.Collagenous spherulosis(5/5)showed focal or diffuse weak positivity;Malignant adenomyoepi-thelioma(3/3)was focally moderately or strongly positive;8 matrix-producing carcinomas and 9 secretory carcinomas and 40 non-specific triple-negative breast cancers were negative.Immu-nohistochemistry of Notch1 showed diffuse moderate positive for SB-AdCC(3/6)and negative for C-AdCC(20/20).3 cases of malignant adenomyoepithelioma,5 cases of collagenous spherulo-sis,8 cases of matrix-producing carcinoma,9 cases of secretory carcinoma and 40 cases of non-specific triple-negative breast cancer were negative.FISH showed MYB gene disruption in C-AdCC(12/19)and NGS showed SB-AdCC(3/6)Notch1 muta-tion.Conclusion Moderately or strongly diffuse expression of MYB and Notch1 by immunohistochemistry can assist in the dif-ferentiation of C-AdCC from SB-AdCC,and it can be further clarified by molecular detection when it is difficult to distinguish malignant adenomyoepithelioma.

Objective:To explore the role and mechanism of P311 in the differentiation of mouse skin fibroblasts (Fbs) into myofibroblasts.Methods:The study was an experimental research. Six 2-day-old male C57BL/6 mouse were used to extract skin Fbs by enzymatic hydrolysis method and routinely cultured. The 1 st to 3 rd passage cells were taken and divided into empty vector group transfected with empty adenovirus and P311 group transfected with P311 high expression adenovirus, and P311+myocardin-related transcription factor A (MRTF-A) small interfering RNA (siMRTF-A) group transfected with P311 high expression adenovirus and siMRTF-A according to the random number table. After 72 h of culture, the cell proliferation vitality of cells in 3 groups was detected by cell counting kit 8, the protein expressions of MRTF-A, α-smooth muscle actin (α-SMA), and serum response factor (SRF) in cells in 3 groups were detected by Western blotting, the collagen gel contraction assay was performed and the 72 h gel contraction rates in 3 groups were calculated. The sample numbers in the above experiments were all 3. The protein expressions of MRTF-A and SRF in cells, cytoplasm, and nucleus in cells in empty vector group and P311 group were detected by Western blotting, with sample number of 4. Results:After 72 h of culture, the cell proliferation vitality of cells in empty vector group, P311 group, and P311+siMRTF-A group was similar ( P>0.05). After 72 h of culture, compared with those in empty vector group, the protein expressions of MRTF-A, α-SMA, and SRF in cells in P311 group were significantly increased ( P<0.05), while the protein expressions of MRTF-A and SRF in cells in P311+siMRTF-A group were significantly decreased ( P<0.05). Compared with those in P311 group, the protein expressions of MRTF-A, SRF, and α-SMA in cells in P311+siMRTF-A group were significantly decreased ( P<0.05). The 72 h gel contraction rate showing cell contractility in P311 group was (84.8±6.2)%, which was significantly higher than (27.8±2.6)% in empty vector group and (24.7±3.2)% in P311+siMRTF-A group (with P values all <0.05). The 72 h gel contraction rates in empty vector group and P311+siMRTF-A group were similar ( P>0.05). After 72 hours of culture, the protein expressions of MRTF-A (with t values of 5.86 and 3.77, respectively, P<0.05) and SRF (with t values of 3.95 and 3.97, respectively, P<0.05) in cells and cytoplasm in P311 group were significantly higher than those in empty vector group, while the protein expressions of MRTF-A and SRF in the nucleus of cells were similar between the two groups ( P>0.05). Conclusions:P311 can promote the differentiation of fibroblasts into myofibroblasts through MRTF-A, and then participate in scar formation.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Background::Endometriosis (EM) is a complex benign gynecological disease, but it has malignant biological behavior and can invade any part of the body. Clinical manifestations include pelvic pain, dysmenorrhea, infertility, pelvic nodules, and masses. Our previous study successfully detected circulating endometrial cells (CECs) in the peripheral blood of patients with EM. The purpose of this study is to overcome the limitation of cell size in the previous microfluidic chip method, to further accurately capture CECs, understand the characteristics of these cells, and explore the relationship between CECs and the clinical course characteristics of patients with EM.Methods::Human peripheral venous blood used to detect CECs and circulating vascular endothelial cells (CVECs) was taken from EM patients ( n = 34) hospitalized in the Peking University People’s Hospital. We used the subtraction enrichment and immunostaining fluorescence in situ hybridization (SE-iFISH) method to exclude the interference of red blood cells, white blood cells, and CVECs, so as to accurately capture the CECs in the peripheral blood of patients with EM. Then we clarified the size and ploidy number of chromosome 8 of CECs, and a second grouping of patients was performed based on clinical characteristics to determine the relationship between CECs and clinical course characteristics. Results::The peripheral blood of 34 EM patients and 12 non-EM patients was evaluated by SE-iFISH. Overall, 34 eligible EM patients were enrolled. The results showed that the detection rates of CECs were 58.8% in EM patients and 16.7% in the control group. However, after classification according to clinical characteristics, more CECs could be detected in the peripheral blood of patients with rapidly progressive EM, with a detection rate of 94.4% (17/18). In total, 63.5% (40/63) of these cells were small cells with diameters below 5 μm, and 44.4% (28/63) were aneuploid cells. No significant association was found between the number of CECs and EM stage.Conclusion::The number and characteristics of CECs are related to the clinical course characteristics of patients with EM, such as pain and changes in lesion size, and may be used as biomarkers for personalized treatment and management of EM in the future.

Objective To study the status of diabetic foot and its related factors in Hanzhong area in recent years, and to provide a scientific basis for the prevention and management of diabetic foot complicated by type 2 diabetes. Methods A stratified sampling method was used to select 528 patients with type 2 diabetes among permanent residents in Hanzhong from April 2016 to April 2022. Relevant medical history and laboratory examination data were collected, and the incidence of diabetic foot was calculated. The influence of related factors on the risk of diabetic foot was analyzed by regression model. Results Among 528 subjects in this study, the disease course and body type of T2DM showed that male patients had significantly longer disease, and the proportion of overweight and obesity was higher, P<0.05. The incidence of diabetic foot was 16.29% (86 cases). The proportion of male patients and female patients was 24.66% and 5.93%（χ²=27.516，P<0.05）. The proportion of male patients complicated with diabetic foot was higher than that of female patients (P<0.05). At the same time, the incidence of Wagner Grade I was higher in males than in females (P<0.05). The effects of potential factors on the risk of diabetic foot were discussed by gender. Univariate analysis and multivariate logistic regression analysis indicated that the risk factors of diabetic foot in male T2DM patients included: Increased course of disease, increased age, poor blood glucose control, increased total cholesterol level, increased BMI level and increased platelet to lymphocyte ratio . Potential risk factors in women include increased course of disease, age, poor blood sugar control (increased glycosylated hemoglobin levels) and increased platelet to lymphocyte ratios in all cases（P<0.05）. Conclusion The current prevalence rate of type 2 diabetes patients complicated with diabetes foot in Hanzhong area is 16.29%, which is still high , and the prevalence rate of men is significantly higher than that of women. Older age, long duration of T2DM, poor blood glucose control, increased total cholesterol level, increased blood uric acid level, decreased urine pH value, and increased platelet lymphocyte ratio are potential risk factors for diabetes foot. Male patients should also pay attention to the occurrence of overweight and obesity tendency to reduce the risk of diabetes foot.
