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.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

This paper summarized Professor ZHANG Zhiwen's clinical experience in treating pulmonary nodules. Professor ZHANG proposed that the pathogenesis of pulmonary nodules is impairment of qi and body fluid distribution， sweating pores constraint and block， binding of phlegm and stasis， and long-term accumulation transforming into toxin， with abnormal circulation of qi， blood and body fluid as the root， and phlegm， stasis and toxin as the branch. According to the evolution of pathogenesis， a dynamic diagnosis and treatment idea of "regulating qi and body fluid， opening sweating pores， penetrating kenang （窠囊）， and preventing cancer toxins" is proposed， including the methods of regulating qi and body fluid， and calming the five zang （脏） organs with the modified self-prescribed Tiaoqi Huatan Decoction （调气化痰汤）， opening sweating pores and unblocking qi and blood with the modified self-prescribed Kaixuan Tongyu Decoction （开玄通郁汤）， penetrating kenang and dissipating masses and stagnation with the modified self-prescribed Tounang Sanjie Decoction （透囊散结汤）， rectifying the healthy qi and preventing cancer toxins with the modified self-prescribed Shenqi Fuzheng Jiedu Decoction （参芪扶正解毒汤）. These four methods can be used alone， in combination， or in sequence， and can provide ideas for the diagnosis and treatment of pulmonary nodules with traditional Chinese medicine.

OBJECTIVE To investigate the relationship between serum LncRNA MALAT1 and miR-204-5p expression and prognosis in patients with supraglottic carcinoma.METHODS From November 2016 to November 2020,118 patients with supraglottic carcinoma who were treated in the Department of Otolaryngology,Baoding First Central Hospital were analyzed,as the observation group,and 118 healthy adults were selected as the control group.The observation group was divided into poor prognosis group(n=20 cases)and good prognosis group(n=98 cases)according to the survival situation.Real-time fluorescence quantitative PCR(qRT-PCR)technology was applied to detect the expression levels of LncRNA MALAT1 and miR-204-5p.Pearson method was applied to analyze the correlation between serum LncRNA MALAT1 and miR-204-5p levels.Receiver operating characteristic(ROC)curves were plotted to analyze the predictive value of serum LncRNA MALAT1 and miR-204-5p levels for the prognosis of patients with supraglottic carcinoma.RESULTS The serum LncRNA MALAT1 level in the observation group was prominently higher than that in the control group(P<0.05),and the miR-204-5p level was prominently lower than that in the control group(P<0.05).The expression level of serum LncRNA MALAT1 was negatively correlated with miR-204-5p(r=-0.487,P<0.001).The levels of serum LncRNA MALAT1 and miR-204-5p were related to T staging,lymph node metastasis,and differentiation degree(P<0.05).The level of serum LncRNA MALAT1 in the poor prognosis group was greatly higher than that in the good prognosis group(P<0.05),while the proportions of T1 stage,no lymph node metastasis,high differentiation,clinical stages Ⅰ-Ⅱ,and the level of serum miR-204-5p were greatly lower than those in the good prognosis group(P<0.05).ROC curve showed that the AUC of LncRNA MALAT1 combined miR-204-5p in predicting the prognosis of supraglottic carcinoma patients was prominently higher than that of LncRNA MALAT1 alone(Z=3.079,P=0.002)and miR-204-5p alone(Z=3.338,P=0.001).CONCLUSION Serum LncRNA MALAT1 level is elevated and serum miR-204-5p level is reduced in patients with supraglottic carcinoma.They have certain value in evaluating the prognosis of patients with supraglottic carcinoma.

Objective:To establish a decision tree model of pediatric complicated appendicitis (CA) based on Pediatric Appendicitis Score (PAS) combined with inflammatory indicators, and to evaluate its clinical application efficacy in pediatrics.Methods:The clinical data of 544 children diagnosed with appendicitis in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021 was retrospectively analyzed. According to postoperative pathology, the children were divided into uncomplicated appendicitis group and CA group. The independent risk factors of CA were screened by univariate and multivariate logistic regression analysis, and these parameters were included to establish the decision tree model. The accuracy of the decision tree model was verified by receiver operating characteristic (ROC) curve.Results:Binary logistic regression analysis indicated that the PAS, C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were identified as independent risk factors for complicated appendicitis in children (all P<0.05). PAS, CRP and NLR were included as covariables to construct the decision tree model and binary logistic regression model for predicting CA. The decision tree demonstrated an overall accuracy of 79.2% with a sensitivity of 86.7% and specificity of 71.9%, and achieved an area under curve (AUC) of 0.821(95% CI: 0.786-0.857). The binary logistic regression model had a sensitivity of 79.6% and specificity of 69.1%, with an overall accuracy of 75.1% and achieved an AUC of 0.808(95% CI: 0.770-0.845). Conclusions:The decision tree model based on PAS score combined with CRP, NLR is a simple, intuitive and effective tool , which can provide pediatric emergency physicians a reliable basis for diagnosis of pediatric CA.

Rotundic acid(RA),an ursane-type pentacyclic triterpene acid isolated from the dried barks of Ilex rotunda Thunb.(Aquifoliaceae),possesses diverse bioactivities.To further study its pharmacokinetics,a simple and sensitive liquid chromatography with triple quadrupole mass spectrometry(LC-QqQ-MS/MS)method was developed and validated to quantify RA concentration in rat plasma and tissue using etofesalamide as an internal standard(IS).Plasma and tissue samples were subjected to one-step protein precipitation.Chromatographic separation was achieved on a ZORBAX Eclipse XDB-C18 col-umn(4.6 mm×50 mm,5 μm)under gradient conditions with eluents of methanol:acetonitrile(1∶1,V/V)and 5mM ammonium formate:methanol(9∶1,V/V)at 0.5mL/min.Multiple reaction monitoring transitions were performed at m/z 487.30 → 437.30 for RA and m/z 256.10 → 227.10 for IS in the negative mode.The developed LC-QqQ-MS/MS method exhibited good linearity(2-500 ng/mL)and was fully validated in accordance with U.S.Food and Drug Administration bioanalytical guidelines.Dose proportionality and bioavailability in rats were determined by comparing pharmacokinetic data after single oral(10,20,and 40 mg/kg)and intravenous(10 mg/kg)administration of RA.Tissue distribution was studied following oral administration at 20 mg/kg.The results showed that the absolute bioavailability of RA after administration at different doses ranged from 16.1％to 19.4％.RA showed good dose proportionality over a dose range of 10-40 mg/kg.RA was rapidly absorbed in a dose-dependent manner and highly distributed in the liver.In conclusion,this study is the first to systematically elucidate the absorption and distribution characteristics of RA in rats,which can provide additional information for further development and evaluation of RA in drug metabolism and pharmacokinetic studies.

Objective:To summarize the experience of arterial duct (AD) stenting in children with ductus-dependent hypoplastic right heart syndrome (HRHS).Methods:Seven children including 4 cases of pulmonary atresia with intact ventricular septum (PA-IVS) with HRHS and 3 cases of critical pulmonary stenosis (CPS)-IVS with HRHS underwent AD stenting in Qingdao Women and Children′s Hospital between January 2012 and January 2019. During the same period, 9 patients of PA-IVS with HRHS received Blalock Taussig (B-T) shunt. Two groups of children on the operation time, hospital stay time, intensive care time and mortality were compared. T test or Mann-Whitney U test was used for comparison between the two groups. Results:There was no significant difference in the age (18 (7-100) vs. 17 (1-142) d, U=31.000, P>0.05) and weight ((3.8±1.1) vs. (3.7±1.3) kg, t=0.272, P>0.05) between the AD stenting group and the B-T group.The operation time ((108±7) vs. (160±49) min, t=-4.304), intensive care time ((3.4±1.0) vs. (6.3±4.5) d, t=-8.692) and total hospitalization time ((10.3±1.0) vs. (26.3±1.0) d, t=-7.822) in the AD stenting group were differed significantly compared with the B-T group (all P<0.05). The transcutaneous oxygen saturation improved significantly (0.723±0.125 vs. 0.926±0.005, t=-6.044, P<0.05) after AD stenting. The diameter of AD stent ranged from 3.5 to 4.0 mm, and the length of AD stent was 16-21 mm. There were no complications such as vascular injury, acute thrombus, catheter spasm and death in the AD stenting group. The mortality of children in the B-T group was 3 in 9 cases. Three cases in the AD stenting group received pulmonary valvulotomy and bilateral Glenn operation at 6, 9 and 9 months after AD stenting, respectively. Conclusions:AD stenting is a feasible, effective, safe and minimally invasive procedure for children with ductus-dependent HRHS. It can even be used as an alternative to B-T shunt.

Leukocyte differentiation antigens (LDAs) play important roles in the immune system, by serving as surface markers and participating in multiple biological activities, such as recognizing pathogens, mediating membrane signals, interacting with other cells or systems, and regulating cell differentiation and activation. Data mining is a powerful tool used to identify novel LDAs from whole genome. LRRC25 (leucine rich repeat-containing 25) was predicted to have a role in the function of myeloid cells by a large-scale "omics" data analysis. Further experimental validation showed that LRRC25 is highly expressed in primary myeloid cells, such as granulocytes and monocytes, and lowly/intermediately expressed in B cells, but not in T cells and almost all NK cells. It was down-regulated in multiple acute myeloid leukemia (AML) cell lines and bone marrow cells of AML patients and up-regulated after all-trans retinoic acid (ATRA)-mediated granulocytic differentiation in AML cell lines and acute promyelocytic leukemia (APL; AML-M3, FAB classification) cells. Localization analysis showed that LRRC25 is a type I transmembrane molecule. Although ectopic LRRC25 did not promote spontaneous differentiation of NB4 cells, knockdown of LRRC25 by siRNA or shRNA and knockout of LRRC25 by the CRISPR-Cas9 system attenuated ATRA-induced terminal granulocytic differentiation, and restoration of LRRC25 in knockout cells could rescue ATRA-induced granulocytic differentiation. Therefore, LRRC25, a potential leukocyte differentiation antigen, is a key regulator of ATRA-induced granulocytic differentiation.
