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.

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 explore the application effect of 5E nursing guided by empowerment theory in patients undergoing liver cancer resection.Methods:Using the purposive sampling method, a total of 88 patients who underwent liver cancer resection surgery in Zhumadian Central Hospital from July 2020 to July 2022 were selected as the research objects. They were divided into the control group ( n=44) and the observation group ( n=44) by the random number table method. The control group was given 5E nursing, while the observation group was given 5E nursing guided by empowerment theory. The improvement of gastrointestinal function between the two groups was compared by the first anal defecation time, the first anal exhaust time and the recovery time of bowel sound. Visual Analogue Scale (VAS) was used to evaluate postoperative pain, General Self-Efficacy Scale (GSES) was used to evaluate self-efficacy, and hope level was assessed by Herth Hope Index (HHI). After treatment, the compliance and occurrence of digestive tract discomfort were compared between the two groups. Results:The first anal defecation time, first anal exhaust time and bowel sound recovery time in observation group were less than those in control group ( P<0.05). Postoperative pain score of observation group was lower than that of control group 48 hours after operation ( P<0.05). After nursing, the GSES, HHI and compliance scores of the observation group were higher than those of the control group ( P<0.05), and the incidence of gastrointestinal discomfort symptoms in the observation group was lower than that in the control group ( P<0.05) . Conclusions:The 5E nursing guided by empowerment theory can effectively improve the compliance, self-efficacy and hope level of liver cancer resection patients, reduce pain, promote postoperative recovery and reduce the incidence of gastrointestinal discomfort symptoms.

Objective:To explore the effectiveness of the O-AMAS teaching model in clinical teaching for blood purification training nurses.Methods:Convenience sampling was used to select 187 training nurses from the Blood Purification Center of the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2022 as research subjects. Eighty training nurses enrolled from January to December 2021 were selected as the control group, and 107 training nurses enrolled from January to December 2022 were selected as the experimental group. After three months of intervention, the training nurses' theoretical scores, operational skills assessment scores, and satisfaction were compared between the two groups.Results:The theoretical and operational skills assessment scores of the experimental group were higher than those of the control group ( P<0.05). The satisfaction of the experimental group with the teaching model, teaching effectiveness, completion of theoretical training, guidance on operational skills, and overall teaching was higher than that of the control group ( P<0.05) . Conclusions:The O-AMAS teaching model for clinical teaching can help improve the training effectiveness and satisfaction of blood purification training nurses.

The clinical practice guidelines for prevention and treatment of postoperative gastrointestinal disorder with Integrated Traditional Chinese and Western Medicine (2023) issued by the Anaesthesia Committee and Perioperative Medicine Committee of the Chinese Society of Integrative Medicine is the first evidence-based guideline for postoperative gastrointestinal disorder in China. It covers the definition, aetiology and pathogenesis, diagnosis and treatment of postoperative gastrointestinal disorder. Compared with previous expert consensus, this guideline has advantages in terms of scientific and rigorous methodology and is quite representative. Interpreting this guideline can help strengthen clinicians′ understanding of postoperative gastrointestinal disorder and enhance clinical practitioners′ understanding of the methodology of this guideline, thus enabling a better integration of recommendations and evidence for clinical practice and hastening the implementation of the guidelines. It also accelerates the dissemination of the methodological development of guidelines in China, helps clinicians understand the connotation and value of the guidelines, and provides methodological guidance and references for formulating clinical practice guidelines based on the current situation in China and involving other clinical disciplines.

Objective:To explore the efficacy and safety of sirolimus in the treatment of diazoxide unresponsive congenital hyperinsulinism(CHI) and summarize the single-center experience.Methods:A retrospective analysis was conducted on the clinical data of 5 cases of CHI treated with sirolimus after ineffective treatment with diazoxide, admitted to the Children′s Hospital Affiliated to Zhengzhou University from January 2017 to December 2022. The efficacy and safety of sirolimus in the treatment of CHI were evaluated.Results:The study included 5 patients, 3 males and 2 females. The age of onset ranged from 1 to 90 days. Initial symptoms included poor mental state(2/5) and convulsions(3/5). Blood glucose levels were 1.1 to 2.3 mmol/L, and insulin levels ranged from 13.52 to 70.53 μIU/mL. Two cases were classified as diffuse type, and the histological type of 3 cases was unknown. Genetic testing confirmed the diagnosis, with whole-exome sequencing revealing an unreported novel mutation in 1 case(ABCC8 exon 25_28del). Of the five patients, three patients were treated with sirolimus after diazoxide and octreotide failed, one patient was treated after unresponsive diazoxide, and the other one was treated after diazoxide, octreotide, and even near-total pancreatectomy failed. The onset age of sirolimus therapy ranged from 1 to 20 months. The maximum dosage of sirolimus was 1.2-3.2 mg·m -2·d -1, and the duration of medication ranged from 2 to 12 months. One patient was fully responsive to sirolimus, and the other four patients were partially responsive. All patients achieved euglycemia with sirolimus alone or in combination with standard CHI treatment. During follow-up, non-infectious diarrhea, elevated carcinoembryonic antigen, elevated triglycerides, and elevated liver enzymes were observed. Conclusion:This study indicates that sirolimus has a certain degree of efficacy in CHI patients for whom diazoxide treatment is ineffective. However, the long-term efficacy and safety warrant further multicenter trials.

Objective:To investigate the safety and effectiveness of endoscopic cold snare resection of small colorectal polyps and prophylactic hemostatic clip.Methods:A total of 260 patients diagnosed as having small colorectal polyps in Qinghai Provincial People's Hospital from January 2021 to March 2022 were randomly assigned to cold snare polypectomy (CSP) group (receiving CSP), CSP+hemostatic clip group (receiving CSP+prophylactic hemostatic clip), hot snare polypectomy (HSP) group, and HSP +hemostatic clip group (receiving HSP+prophylactic hemostatic clip). Each group had 65 cases. The treatment, incidence of bleeding, and other complications were compared.Results:There was no significant difference in the basic characteristics of patients or polyps among the four groups ( P>0.05). Immediate intraoperative bleeding occurred in 5 cases (7.69%), 4 cases (6.15%), 3 cases (4.62%), and 3 cases (4.62%) in the four groups respectively with no significant difference ( χ2=0.778, P=0.855), while only 1 delayed postoperative bleeding was observed in HSP group with no significant difference among the four groups ( χ2=3.012, P=0.390). The incidence of postoperative abdominal pain was the highest in the HSP group ( n=7, 10.77%) significantly different from those of the CSP group ( n=1, 1.54%) and the CSP+hemostatic clip group ( n=1, 1.54%) ( P<0.05). Polypectomy time of single polyp in CSP group was the shortest (2.18±1.07 min) , followed by HSP group (2.83±0.82 min), then CSP+hemostatic clip group (3.15±1.16 min), with HSP+hemostatic clip group (4.88±1.85 min) being the longest ( F=50.397, P<0.001). Conclusion:It is suggested to use CSP for small colorectal polyps. If there is no risk of bleeding or perforation during the operation, it is not necessary to use prophylactic hemostatic clips.

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.
