Objective To observe the clinical efficacy of modified Shoutai Pills in the treatment of polycystic ovary syndrome(PCOS)complicated with recurrent spontaneous abortion(RSA).Methods Ninety-six patients with PCOS complicated with RSA of kidney deficiency and blood stasis syndrome admitted to Lishui Hospital of Traditional Chinese Medicine from January 2021 to January 2022 were randomly divided into the observation group and the control group,with 48 cases in each group.The control group was treated with progesterone,aspirin and low molecular weight heparin,while the observation group was treated with modified Shoutai Pills on the basis of treatment for the control group.The course of treatment covered one month and then the follow-up lasted for one year.The changes of traditional Chinese medicine(TCM)syndrome scores,ovarian reserve function indicators of antral follicle count and mean ovarian volume,and coagulation and fibrinolysis indicators of fibrinogen(FIB),activated partial thromboplastin time(APTT),prothrombin time(PT),and D-dimer(D-D)level before and after the treatment in the two groups were observed.After treatment,the clinical efficacy,total incidence of adverse reactions and pregnancy outcome of the two groups of patients were compared.Results(1)After one month of treatment,the total effective rate of the observation group was 95.83%(46/48),and that of the control group was 72.92%(35/48);the comparison between the two groups showed that the overall efficacy(tested by Ridit test)and the total effective rate(tested by chi-square test)of the observation group were significantly superior to those of the control group(P<0.05).(2)After treatment,the scores of spontaneous abortion frequency and TCM symptoms such as pain in the lower abdomen,fatigue and weakness,and dizziness and tinnitus in the two groups were decreased compared with those before treatment(P<0.05),and the decrease of the scores in the observation group was significantly superior to that in the control group(P<0.05).(3)After treatment,ovarian reserve function indicators of antral follicle count and mean ovarian volume in the two groups were improved compared with those before treatment(P<0.05),and the improvement in the observation group was significantly superior to that in the control group(P<0.05).(4)After treatment,coagulation and fibrinolysis indicators such as FIB,APTT,PT,and D-D in the two groups were improved compared with those before treatment(P<0.05),and the improvement in the observation group was significantly superior to that in the control group(P<0.05).(5)The total incidence of adverse reactions in the observation group was 6.25%(3/48),while that in the control group was 10.42%(5/48),and the comparison between the two groups showed that the difference was not statistically significant(P>0.05).(6)The rate of full-term delivery in the observation group was 87.50%(42/48),higher than that in the control group[45.83%(22/48)];the preterm birth rate and abortion rate of the observation group were 8.33%(4/48)and 4.17%(2/48),respectively,lower than those of the control group[all being 27.08%(13/48)],with the differences being statistically significant(P<0.05 or P<0.01).Conclusion Modified Shoutai Pills can effectively improve the ovarian function of patients with PCOS complicated with RSA,correct the hypercoagulable state,relieve abdominal pain and other symptoms,reduce the rate of preterm birth and abortion,and no obvious adverse reactions occurred in the patients during treatment.

In recent years,with the continuous advancement of deep space exploration missions,astronauts have been increasingly exposed to complex and extreme environmental factors in space,such as microgravity,space radiation,circadian rhythm disruption,and confined isolation.These conditions can easily induce brain dysfunction in astronauts,manifesting as cognitive decline,emotional disturbances,sleep disorders,and neuroinflammatory responses.Traditional Chinese Medicine(TCM),characterized by its holistic regulation and syndrome differentiation-based treatment principles,exhibits multi-target regulation and systemic coordination,and has attracted growing attention in the field of brain function protection.This study systematically reviews the protective applications and research progress of TCM and related techniques in both actual spaceflight missions and simulated space environment models against brain functional disorders.The underlying mechanisms and future prospects are discussed,with the aim of providing insights for safeguarding astronauts'brain health and laying a theoretical foundation for the precise intervention and systematic protection strategies of TCM in future deep space missions.

Objective To evaluate the clinical safety and efficacy of NOVA stent implantation in the treatment of symptomatic middle cerebral artery(MCA)atherosclerotic stenosis.Methods The clinical data,including surgical results,perioperative complications,imaging manifestations and follow-up findings,of 21 patients with severe MCA atherosclerotic stenosis,who received NOVA stent implantation at the Affiliated Tongji Hospital of Tongji University of China from November 2021 to February 2023,were retrospectively analyzed.Results Successful NOVA stent implantation was accomplished in all the 21 patients.The residual stenosis was less than 30％,with no bleeding complications.After stent implantation,the median stenosis ratio of responsible vessels decreased from preoperative 85.04％to postoperative 5.95％,the difference was statistically significant(P＜0.01).During the follow-up period of 10-14 months,one patient(4.76％)developed in-stent restenosis,one patient developed transient ischemic attack(TIA),and one patient developed posterior circulation cerebral infarction.No cerebral hemorrhage or death occurred.After treatment,the clinical symptoms were stable in 16 patients(76.19％),improved in 4 patients(19.04％),and worsened in one patient(4.76％).Conclusion For the treatment of patients with symptomatic MCA atherosclerotic stenosis,NOVA stent implantation is clinically safe and effective.However,multicenter randomized controlled studies with larger sample size and longer follow-up period need to be conducted before its curative efficacy can be further validated.

Objective:To investigate the impact of the number of cesarean deliveries on adverse maternal and neonatal outcomes.Methods:A retrospective analysis was conducted on 11 904 singleton pregnant women who underwent cesarean delivery at the Third Affiliated Hospital of Guangzhou Medical University from January 1st, 2019 to December 31st, 2023. The women were grouped according to the number of cesarean deliveries: those undergoing their first cesarean delivery (1CD group, 7 231 cases), those undergoing their second cesarean delivery (2CD group, 3 749 cases), those undergoing their third cesarean delivery (3CD group, 841 cases), and those undergoing their fourth or more cesarean deliveries (4CD group, 83 cases). Differences in clinical characteristics, related surgical procedures, and adverse maternal and neonatal outcomes among the groups were compared. Binary logistic regression analysis was used to assess the impact of the number of cesarean deliveries on related surgical procedures and adverse maternal and neonatal outcomes.Results:(1) During the 5-year period, the total number of women undergoing cesarean delivery in our hospital showed a slight downward trend, while the proportion of women undergoing three or more cesarean deliveries increased. (2) Compared with women undergoing their first cesarean delivery, women in each repeat cesarean delivery group were older, had higher proportions of advanced maternal age and pre-pregnancy body mass index, and had more pregnancies, deliveries, and induced abortions; the incidence of placenta previa, placental implantation, antepartum hemorrhage, gestational hyperglycemia, and failed trial of labor requiring conversion to surgery was higher, while the incidence of premature rupture of membranes was lower; the proportions of ureteral stent placement, adhesiolysis of the pelvic and abdominal cavities, uterine rupture, uterine reconstruction, uterine artery ligation, hysterectomy, postpartum hemorrhage, and postoperative intestinal obstruction were higher, and the amount of postpartum hemorrhage was greater; the gestational age at delivery of neonates was earlier, but the rates of preterm birth at 28-31 +6 and 32-33 +6 weeks of gestation were lower; the differences were statistically significant ( P<0.05) for all comparisons. (3) The number of cesarean deliveries was not an independent risk factor for the dose-dependent occurrence of placenta previa (a OR=0.99, 95% CI: 0.98-1.01; P=0.261). In women without placenta previa, the number of cesarean deliveries was not a risk factor for placental implantation (a OR=1.12, 95% CI: 0.90-1.39; P=0.320). However, in women with placenta previa, the number of cesarean deliveries was a risk factor for placental implantation (a OR=4.01, 95% CI: 3.08-5.22; P<0.001). In the overall population, the number of cesarean deliveries was a risk factor for ureteral stent placement, adhesiolysis of the pelvic and abdominal cavities, bladder rupture repair, uterine rupture, uterine reconstruction, uterine artery ligation, hysterectomy, postpartum hemorrhage, and preterm birth (all P<0.05). However, the number of cesarean deliveries was not a risk factor for postoperative intestinal obstruction, admission to the intensive care unit, neonatal asphyxia, admission to the neonatal intensive care unit, or neonatal death (all P<0.05). Conclusions:The number of cesarean deliveries could lead to adverse maternal and neonatal outcomes, but the relationship is not simply dose-dependent. It is speculated that the occurrence of severe adverse maternal and neonatal outcomes is more closely related to maternal complications and comorbidities, as well as whether multidisciplinary comprehensive management was received.

Objective To evaluate the application value of intraoperative optical coherence tomography(iOCT)in the treat-ment of idiopathic macular holes(IMH)using various surgical techniques.Methods A retrospective analysis was conducted on patients who underwent vitrectomy assisted by iOCT for IMH at Wuhan No.1 Hospital from January 2021 to December 2021.All the included patients were categorized based on the different surgical methods:internal limiting membrane(ILM)peel-ing,inverted ILM coverage,and ILM filling.All patients underwent iOCT examinations to assess morphological changes in the retinal layers of the macular region,the integrity of ILM peeling,the morphology of the macular hole edges,and any intraopera-tive retinal microdamage.The closure rates of macular holes,changes in best-corrected visual acuity(BCVA),and postoperative complications were compared among three surgical approaches.Results After selection,a total of 72 patients were included in the study,consisting of 23 males and 49 females,with an average age of(57.88±7.21)years and a follow-up period of 6 months.After completing ILM peeling,iOCT revealed morphological changes at the edges of the macular holes in 15 eyes,and intraoperative retinal microdamage occurred in 18 eyes(25％).Among these,12 eyes exhibited abnormalities in the nerve fiber layer,such as hemorrhage,while 6 showed mild elevation of the inner retinal structures.iOCT indicated that 8 eyes(11.1％)still had remnants of the anterior membrane after the initial peeling,suggesting incomplete peeling and a second peeling was per-formed.The remaining 64 eyes had complete peeling.BCVA significantly improved in the ILM peeling group,ILM filling group,and ILM inversion coverage group at 1 week,1 month,and 6 months post-surgery compared to preoperative values(P＜0.05).The closure rates for the macular holes in the ILM peeling group,ILM filling group,and ILM inversion coverage group were 89.7％,91.3％,and 95.0％,respectively,with no significant differences among the groups(P＞0.05).No severe complication related to the surgical procedure was observed in any of the three groups during or after surgery.Conclusion ILM peeling,ILM filling,and ILM inversion coverage are all effective surgical techniques for treating IMH.iOCT can clearly and dynamically ob-serve the morphology of the retina in the macular area in real time during the operation,especially the subtle structural changes of the macular hole.It is beneficial to improve the surgeon's understanding of the surgical area,guide the operation,optimize the surgical decision,and improve the postoperative visual acuity of patients.

Despite that sleep disturbance and poor neurocognitive performance are common complaints among coronavirus disease 2019 (COVID-19) survivors, few studies have focused on the effect of post-COVID-19 sleep disturbance (PCSD) on cognitive function. This study aimed to identify the impact of PCSD on neurocognitive function and explore the associated risk factors for the worsening of this condition. This cross-sectional study was conducted via the web-based assessment in Chinese mainland. Neurocognitive function was evaluated by the modified online Integrated Cognitive Assessment (ICA) and the Number Ordering Test (NOT). Propensity score matching (PSM) was utilized to match the confounding factors between individuals with and without PCSD. Univariate analyses were performed to evaluate the effect of PCSD on neurocognitive function. The risk factors associated with worsened neurocognitive performance in PCSD individuals were explored using binary logistic regression. A total of 8692 individuals with COVID-19 diagnosis were selected for this study. Nearly half (48.80%) of the COVID-19 survivors reported sleep disturbance. After matching by PSM, a total of 3977 pairs (7954 individuals in total) were obtained. Univariate analyses revealed that PCSD was related to worse ICA and NOT performance (P<0.05). Underlying disease, upper respiratory infection, loss of smell or taste, severe pneumonia, and self-reported cognitive complaints were associated with worsened neurocognitive performance among PCSD individuals (P<0.05). Furthermore, aging, ethnicity (minority), and lower education level were found to be independent risk factors for worsened neurocognitive performance in PCSD individuals (P<0.05). PCSD was related to impaired neurocognitive performance. Therefore, appropriate prevention and intervention measures should be taken to minimize or prevent PCSD and eliminate its potential adverse effect on neurocognitive function.

PANoptosis is a type of programmed cell death regulated by the PANoptosome with key features of pyroptosis, apoptosis and/or necroptosis. As the most complex programmed cell death, PANoptosis emphasizes the compensatory role among multiple programmed cell deaths, and can regulate malignant phenotypes such as proliferation, migration, and invasion of tumor cells through multiple signaling pathways, thus affecting malignant tumor progression. It has been found that PANoptosis plays a dual role in tumor progression and treatment. Therefore, it is clinically important to understand the molecular mechanisms by which PANoptosis affects tumorigenesis, development and progression. This paper reviews the molecular mechanisms of apoptosis, pyroptosis and necroptosis, and discusses the activation and regulation mechanisms of PANoptosis and PANoptosome as well as the research progress on the role of PANoptosis in tumors, aiming to provide new ideas for cancer treatment and prognostic assessment.

Background/Aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA. Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival. Results: Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016). Conclusions The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.
