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.

Elderly end-of-life patients often experience distress due to being caught in dilemmas of contemplation and decision-making. Narrative wills, grounded in life values and premised on respecting individual wishes and needs, present an individual’s unique life story through narrative forms, conveying their overall experience, interpretation of meaning, and understanding of life. They are preserved and passed on in a way that meets individual expectations, thereby promoting human exploration, reflection, and growth regarding the meaning of life through interpersonal interactions that transcend space and time. This paper explored the concept of narrative wills among elderly end-of-life patients, the ethical value and ethical principles of narrative wills, and the moral and ethical risks. It also provided specific ethical interpretations, assisting in the application and development of narrative wills in elderly end-of-life patients.

ObjectiveTo establish a qualitative and quantitative analysis method for chemical constituents in Liu Junzitang(LJZT), and to clarify its material basis. MethodThe chemical constituents in LJZT were analyzed by ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS), and the resulting compounds were identified by using databases, such as MassBank, PubChem, ChemSpider, Traditional Chinese Medicine Systems Pharmacology Database and Analytical Platform(TCMSP), and by combining with relevant literature. UPLC was used to establish a quantitative method for analysis of 9 compounds in LJZT, including liquiritin, hesperidin, lobetyolin, liquiritigenin, glycyrrhizic acid, nobiletin, tangeretin, atractylenolide Ⅱ and Ⅰ. ResultBy combining the relevant literature, database and MS information, a total of 79 compounds were identified from LJZT, including 31 flavonoids, 15 terpenoids, 14 nitrogen-containing compounds, 6 phenylpropanoids, 6 organic acids and 7 other compounds. The established quantitative analytical method for the nine representative components showed good linearity within their respective linear ranges, and the precision, stability, reproducibility and recovery were in accordance with the requirements. The quantitative results showed that the contents of liquiritin, hesperidin, lobetyolin, liquiritigenin, glycyrrhizic acid, nobiletin, tangeretin, atractylenolide Ⅱ and Ⅰ in LJZT were 0.376 5, 2.602 1, 0.082 6, 0.128 1, 1.778 6, 0.015 7, 0.006 7, 0.030 4, 0.003 2 mg·g-1, respectively. ConclusionThe established method can quickly, sensitively and accurately analyze the chemical constituents in LJZT, clarify that the material basis of LJZT is mainly flavonoids, terpenoids and nitrogen-containing compounds, and simultaneously determine the contents of the 9 components, which can lay a foundation for the research on quality control, mechanism and clinical application of LJZT.

Objective:To investigate the distribution characteristics of urinary tract pathogens in patients with community-acquired urinary tract infection and their sensitivity to nenoxacin and levofloxacin.Methods:This prospective, multicenter clinical trial included patients with community-acquired urinary tract infection who were admitted to urological clinics at 9 clinical research centers from November 2021 to August 2022.Inclusion criteria: Patients aged 18-70 years with community-acquired acute uncomplicated cystitis(AUC), recurrent acute episodes of urinary tract infection(rUTI), and non-febrile complicated urinary tract infection(cUTI) with signs of urinary tract irritation and abnormal elevation of routine white blood cells in urine. Exclusion criteria: ①Patients who received effective antimicrobial therapy within 72 h before enrollment and lasted for more than 24 h. ②Fever (>37.3℃) or symptoms of upper urinary tract infection such as low back pain, tapping pain in the kidney area, etc. ③Indwelling urinary catheter. At the first visit, clean midstream urine samples were taken for bacterial culture, and the distribution characteristics of urinary pathogens of different types of urinary tract infections were analyzed. Extended spectrum β-lactamases (ESBLs) were measured for Gram-negative bacteria. The susceptibility of nenoxacin and levofloxacin to urinary tract pathogens was determined by disk diffusion method. Drug resistance rate, sensitivity rate were analyzed between different disease groups.Results:There were 404 enrolled patients from 9 hospitals, including 364 (90.1%) females and 40 (9.9%) males. A total of 177 strains of pathogenic bacteria were isolated, among which the highest proportion of Escherichia coli was 66.1% (117/177).Klebsiella pneumoniae was followed by 6.8% (12/177) and Streptococcus agalactis 5.1% (9/177). The bacterial spectrum distribution of AUC and rUTI were similar, and the proportions of Escherichia coli were 70.6% (85/119) and 65.9% (29/44), respectively. However, the proportions of Escherichia coli isolated from cUTI patients were only 28.6% (4/14) and Enterococcus faecalis 7.1%(1/14). The overall detection rate of ESBLs in Gram-negative bacteria was 30.9%(43/139). The sensitivity rate of nenoxacin was 74.6%(91/122), and the resistance rate was 25.4%(31/122). The overall sensitivity rate of levofloxacin was 44.9%(70/156) and the resistance rate was 36.5%(57/156). The rate of resistance of urinary tract pathogens to levofloxacin was 48.2% (27/56) in patients with previous urinary tract infection history, and 30.0% (30/100) in patients with no previous urinary tract infection history, the difference was statistically significant( P=0.023).The sensitivity rate of Gram-negative bacteria to nenofloxacin was 70.7% (65/92) and that to levofloxacin was 50.0% (46/92, P<0.001). The sensitivity of Gram-positive bacteria to nenofloxacin was 80.0% (16/20), and that to levofloxacin was 70.0% (14/20, P=0.009). Conclusions:The bacterial profile of out-patient community acquired urinary tract infection varies greatly according to different diseases. The proportion of Escherichia coli in AUC and rUTI patients is higher than that in cUTI. The detection rate of ESBLs in Gram-negative bacteria was lower than the domestic average.Patients with a history of urinary tract infection had a high risk of treatment failure with levofloxacin. The sensitivity of common urinary tract pathogens to nenofloxacin was higher than levofloxacin.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

OBJECTIVE To explore the impact and mechanism of curcumin on endometriosis (EMS) model rats based on Notch1 signaling pathway. METHODS Female SD rats with synchronized estrous cycles were implanted with autologous endometrium on the abdominal wall to construct EMS model. EMS rats were randomly divided into model group, low-, medium- and high-dose groups of curcumin (60, 120, 240 mg/kg), and Notch 1 inhibitor DAPT group (7 mg/kg). The sham surgery group was also established, with 10 rats in each group. Rats in each group received intragastric administration or injection via caudal veins with the corresponding drugs for 4 weeks. Endometriotic lesions were observed and measured using ultrasound and visual inspection, and their volumes were calculated. Histopathological morphology of the lesion tissues was observed. The levels of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) in the abdominal cavity fluid, as well as the mRNA and protein expression levels of Notch1, matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor (VEGF) in the endometriotic lesions were measured. RESULTS Compared with the model group, the volume of endometriotic lesions in the low- , medium- and high-dose groups of curcumin and the DAPT group was significantly decreased (P<0.05); atrophy or disappearance of columnar epithelium, cyst disappearance; the levels of IL-1β, IL-6, and TNF- α (except for the low-dose curcumin group) in the abdominal cavity fluid, as well as the mRNA (except for MMP-9 and VEGF in the low-dose curcumin group) and protein (except for MMP-9 in the low-dose curcumin group) expression levels of Notch1, MMP-9, and VEGF in the endometriotic lesions were significantly decreased (P<0.05). The curcumin high-dose group and DAPT group showed superior results in most indicators compared to the curcumin low- and medium-dose groups. CONCLUSIONS Curcumin has an improving effect on EMS, and its mechanism may be related to inhibiting Notch1 signaling pathway, reducting local inflammatory responses, and inhibiting ectopic endometrial invasion and angiogenesis.

Objective:
To evaluate the preventive effect of implementing the free influenza vaccination policy on school absence among primary and secondary school students, so as to provide a reference for formulating and adjusting vaccination strategies.
Methods:
Among primary and secondary school students aged 6 to 18 in Longgang District, Shenzhen, they were divided into a vaccinated group (265 996 students) and an unvaccinated group (122 513 students) according to their influenza vaccination history during November 2023. Propensity score matching was used to conduct a 1∶1 match between the two groups to balance covariates. The number of absences per month was set as the dependent variable to construct a difference in differences model, and Poisson regression was employed to analyze the overall and multi time point effects.
Results:
Vaccination against influenza was associated with low rate of absenteeism among primary and secondary school students, with an overall preventive effect of 26.52% (95% CI = 23.47% -29.45%). The preventive effects in November (the month of vaccination) and December 2023, January and March 2024 were 42.12%, 40.12%, 30.33% and 20.91%, respectively. The preventive effect of the influenza vaccine on absenteeism among primary school students (26.39%) was not significantly different from that among secondary school students ( 27.97% ) ( P >0.05). The regression coefficient for class vaccination rates ranged from 0.998 to 0.999 ( P <0.01), indicating that for every 10% increase in influenza vaccination rates, absenteeism could be reduced by 1.5% to 2.2%.
Conclusion
Implementing free influenza vaccination for primary and secondary school students might help to reduce the risk of absenteeism, yielding significant socioeconomic benefits.
