Objective To explore the relationship between lacune of presumed vascular origin and spontaneous HT in elderly patients with AIS.Methods A total of 671 AIS patients hospitalized in our hospital from January 2021 to September 2024 were prospectively recruited.According to the conditions of lacune of presumed vascular origin by the first cranial MRI examination after admis-sion,they were divided into 330 cases with lacune of presumed vascular origin and 341 cases with-out,and based on the re-examination of head CT or MRI during hospitalization,they were also as-signed into a HT group(139 cases)and a non-HT group(532 cases).Multivariate logistic regres-sion analysis was conducted to clarify the correlation between lacune of presumed vascular origin and spontaneous HT in the elderly AIS patients.The incidence of spontaneous HT and the differ-ences in the subtype composition of spontaneous HT were compared between the mild and severe groups of lacune of presumed vascular origin.Results Baseline NIHSS score,atrial fibrillation,white matter lesions,enlarged perivascular spaces,cerebral microbleeds,large-area cerebral infarc-tion,and ratio of lacune of presumed vascular origin were significantly higher in the HT group than the non-HT group[(10(6,13)vs 9(5,12),P=0.000;28.1％vs 18.0％,P=0.009;74.8％vs 56.0％,P=0.000;79.9％vs 57.5％,P=0.000;30.2％vs 16.9％,P=0.000;45.3％vs 13.2％,P=0.000;66.2％vs 44.7％,P=0.000].The incidence of spontaneous HT was significantly high-er in the lacune of presumed vascular origin group than the non-lacune of presumed vascular ori-gin group(27.9％vs 13.8％,P=0.000).Multivariate logistic regression analysis indicated that lacune of presumed vascular origin was an independent risk factor for spontaneous HT after AIS(OR=2.207,95％CI:1.231-3.959).Subtype analysis on spontaneous HT showed that the patients with lacune of presumed vascular origin had the largest proportion among all subtypes than the non-lacune of presumed vascular origin patients.The incidence of spontaneous HT was significantly higher in the severe lacune of presumed vascular origin group than the mild group(38.1％vs 20.9％,P=0.001).HI2 subtype was mainly observed in the severe group with sponta-neous HT,and HI1 subtype was in the mild group with spontaneous HT.Conclusion Lacune of presumed vascular origin is an independent risk factor for spontaneous HT after AIS in elderly patients.The patients with severe lacune of presumed vascular origin are prone to the occurrence and severe spontaneous HT than the mild lacunar patients.

Objective To explore the effect of the combined application of ciprofol and remifentanil in painless fiberoptic bronchoscopy on the quality of recovery and inflammatory response.Methods 90 patients who underwent painless fiberoptic bronchoscopy from October 2023 to October 2024 were selected and randomly divided into the ciprofol combined with remifentanil group(observation group)and the propofol combined with remifentanil group(control group),with 45 cases in each group.The changes of hemodynamic indicators and BIS of the two groups of patients were compared at the time of entering the room(T0),immediately after the laryngeal mask was placed(T1),when the endoscope entered the tracheal protrusion(T2),at the end of the examination(T3),and 5 min after the laryngeal mask was removed(T4).The scores of the quality of recovery-40(QoR-40)before and after fiberoptic bronchoscopy,the levels of serum inflammatory factors,the time of fiberoptic bronchoscopy,the time to complete the instructed actions and the occurrence of adverse reactions were compared between the two groups of patients.Results The expression levels of serum tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-6(IL-6)at time point T4 in the observation group were significantly lower than those in the control group,and the differences were statistically significant(P＜0.05).The comparison of BIS at T0,T1,T2,T3 and T4 time points between the two groups of patients showed no statistically significant differences(P＞0.05).The mean arterial pressure(MAP)at T,time point in the control group was significantly lower than that in the observation group,and the difference was statistically significant(P＜0.05).There was no statistically significant difference in the comparison of fiberoptic bronchoscopy examination time and the time to complete the instructed actions between the two groups of patients(P＞0.05).There was no statistically significant difference in the QoR-40 score at T0 time point between the two groups of patients(P＞0.05).At T4 time point,the comfort level,emotional state and total score of QoR-40 in the observation group were significantly higher than those in the control group,and the differences were statistically significant(P＜0.05).No serious adverse reactions occurred in either group.The incidence of hypotension in the control group was 22.2％,significantly higher than 4.4％in the observation group,and the difference was statistically significant(P＜0.05).The symptoms were relieved after fluid replacement and appropriate use of vasoactive drugs.The incidence of injection pain in the observation group was significantly lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion The combined application of ciprofol and remifentanil in painless fiberoptic bronchoscopy is safe and effective.It has good sedative and analgesic effects,stable hemodynamics in patients,no obvious injection pain,can effectively reduce the level of inflammation cytokines,improve the quality of early recovery and patient comfort.It is worth applying in clinical practice.

Objective:To analyze the incidence of pregnancy complications and maternal-neonatal outcomes in women with a history of preconception metabolic and bariatric surgery (MBS).Methods:This study was a retrospective cohort study. Pregnant women with singleton pregnancy who delivered in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, from September 2019 to December 2024 were selected as the observation subjects. After propensity score matching, 42 women in the MBS group and 157 women in the control group were finally included. The general clinical characteristics, pregnancy status and maternal-neonatal outcomes of the two groups were compared and analyzed.Results:(1) There were no statistically significant differences in the age, proportion of preconception obesity, chronic hypertension, preconception diabetes and primipara between the MBS group and the control group (all P>0.05). The median interval between surgery and pregnancy of pregnant women in the MBS group was 14.0 months (6.0, 27.5 months). Twenty-nine pregnant women (69%, 29/42) were pregnant after 1 year of surgery, and 13 pregnant women (31%, 13/42) were pregnant within 1 year. (2) The levels of hemoglobin, serum iron and triglyceride in the MBS group were significantly lower than those in the control group in the second and third trimester (all P<0.05), but there were no statistically significant differences in the levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol and albumin between the two groups (all P>0.05). (3) Compared with the control group, the incidence of gestational diabetes mellitus in MBS group [21.7% (34/157) vs 7.1% (3/42)] and the proportion of large for gestational age [23.6% (37/157) vs 2.4% (1/42)] were lower; the incidence of anemia [6.4% (10/157) vs 33.3% (14/42)], fetal growth restriction [7.0% (11/157) vs 23.8% (10/42)] and small for gestational age [3.8% (6/157) vs 19.0% (8/42)] were higher; the differences were statistically significant (all P<0.05). There were no significant differences in the cesarean section rate, premature rupture of membranes rate, postpartum hemorrhage ≥1 000 ml rate, gestational age at delivery and preterm birth rate between the two groups (all P>0.05). The neonatal birth weight of the MBS group was significantly lower than that of the control group [(3 044±523) vs (3 256±491) g, P=0.016], but the proportion of neonates with 1-minute Apgar score<7 and the rate of neonatal intensive care unit admission were not statistically significant (all P>0.05). Conclusions:Women who got pregnant after MBS had lower neonatal weight, decreased incidence of gestational diabetes mellitus and large for gestational age, but higher incidence of small for gestational age and anemia in late pregnancy. It is necessary to focus on the nutritional management of pregnant women with MBS before pregnancy, improve anemia, and strengthen the ultrasound follow-up of fetal growth to optimize the perinatal outcome.

Objective:Under the background of the"Healthy Shanxi 2030"strategy,it systematically analyzes the spatiotemporal evolution characteristics and equilibrium of health resource allocation in Shanxi Province,and explores the optimization path to promote the high-quality development of health care.Methods:Based on the health statistics of Shanxi Province from 2012 to 2023,it systematically analyzes the spatiotemporal evolution characteristics and equilibrium of health resource allocation in Shanxi Province by using Gini coefficient,Theil index and statistical description method.Results:The total number of health resources in Shanxi Province continues to grow steadily,and by the end of 2023,the total number of medical and health institutions in the province will reach to 37 838,the number of hospital beds will reach to 223 650,and the total number of health technicians will be 260 536.Despite this,the imbalance of regional allocation is still significant,showing a"core-periphery"structure.According to the calculation of the Gini coefficient and the Theil index,from 2011 to 2023,the overall equilibrium of the health resources allocation in Shanxi Province showed a gradual improvement trend,which was reflected in the fact that the Gini coefficient of the number of health institutions decreased from 0.287 to 0.268,and the Theil index decreased by 42.40％.However,the structural imbalance of key human resources such as registered nurses is still significant,and the Gini coefficient continues to be higher than 0.30.The regional differences are mainly due to the economic gradient differentiation,policy orientation and population aging pressure,among which the Gini coefficient in the Jinzhong region group is 0.33,and the contribution of regional differences to the overall imbalance is more than 51.00％.Conclusion:Promote the balanced allocation of health resources and help achieve the strategic goal of"Healthy Shanxi"by optimizing the spatial distribution of resources,strengthening the capacity of grassroots services,improving the talent training and mobility mechanism,and deepening the reform of the hierarchical diagnosis and treatment system.

Objective:To investigate the use of treatment measures in patients with severe postpartum hemor-rhage and massive blood transfusion.Methods:A retrospective analysis was conducted on the clinical data of parturients from 18 medical institutions who gave birth between January 2019 and June 2023,with postpartum hemorrhage≥ 1000 ml within 24 hours after delivery and red blood cell(RBC)transfusion≥4 U.According to the amount of RBC transfusion,the patients were divided into massive-transfusion(MT)group(≥ 10 U)and non-massive-transfusion(non-MT)group(4-＜10 U).The high-risk factors for postpartum hemorrhage,causes of hemorrhage,and medical and surgical treatment measures were compared between the two groups.Results:A total of 575 patients were included(134 cases in MT group and 441 cases in non-MT group).In the MT group,the proportions of multiparous women,gravidity≥2,preterm birth,previous cesarean section,placenta previa,and placenta accreta were significantly higher than those in the non-MT group,with statistically significant differences(P＜0.05).The primary cause of postpartum haemorrhage in the MT group was placental factors(58.2％),whereas uterine atony was the main cause in the non-MT group(52.2％).Analysis of medication treatment showed that carboprost tromethamine was the most frequently used secondary uterotonic in both groups(73.1％and 80.5％).Surgical management analysis revealed that the proportion of surgical interventions was higher in the MT group than that in the non-MT group.Among the 44 patients who underwent hysterectomy,33 cases un-derwent hysterectomy during cesarean section,with the primary cause of postpartum haemorrhage being placen-tal factors(29 cases,87.9％).Conclusion:Patients with severe postpartum haemorrhage requiring massive transfusion need extensive pharmacological and surgical interventions.It is crucial to reduce risk factors,particu-larly by decreasing the incidence of primary cesarean sections,optimize uterotonic use,and ultimately minimize the occurrence of severe postpartum haemorrhage and massive transfusion.

BACKGROUND: Pulmonary arterial hypertension (PAH) presents a significant health burden in Asia and remains a critical challenge. This study aims to delineate the PAH burden in Asia from 1990 to 2021. METHODS: Using the latest data from the Global Burden of Disease 2021, we evaluated and analyzed the distributions and patterns of PAH disease burden among various age groups, sexes, regions, and countries in Asia. Additionally, we examined the associations between PAH disease burden and key health system indicators, including the socio-demographic index (SDI) and the universal health coverage (UHC) index. RESULTS: In 2021, there were 25,989 new PAH cases, 103,382 existing cases, 13,909 PAH-associated deaths, and 385,755 DALYs attributed to PAH in Asia, which accounted for approximately 60% of global PAH cases. The age-standardized rates (ASRs) for prevalence and deaths were 2.05 (95% uncertainty interval [UI]: 1.66-2.52) per 100,000 population and 0.31 (95% UI: 0.23-0.38) per 100,000 population, respectively. From 1990 to 2021, Asia reported the lowest ASRs for PAH prevalence but the highest ASRs for deaths compared to other continents. While the ASRs for prevalence increased slightly, ASRs for mortality and DALYs decreased over time. This increasing burden of PAH was primarily driven by population growth and aging. The burden was especially pronounced among individuals aged ≥60 years and <9 years, who collectively accounted for the majority of deaths and DALYs. Moreover, higher SDI and UHC levels were linked to reduced incidence, but higher prevalence rates. CONCLUSIONS Although progress has been made in reducing PAH-related mortality and DALYs, the disease continues to impose a substantial burden in Asia, particularly among older adults and young children. Region-specific health policies should focus on improving early diagnosis, expanding access to treatment, and effectively addressing the growing PAH burden in the region.

Objective:The impact of bystander CD8 + T cells (CD8 + Tbys) within the tumor microenvironment on the prognosis of early-stage non-small cell lung cancer (NSCLC) remains unclear, particularly concerning their infiltration differences at the invasive margin (IM) and tumor center (TC). Methods:We retrospectively collected postoperative specimens from 173 patients with primary early-stage NSCLC who underwent radical surgery at the Affiliated Tumor Hospital of Shandong First Medical University from 2014 to 2018. Tissue microarrays encompassing IM and TC regions were prepared and subjected to multicolor immunofluorescence staining (CK/CD8/CD103/DAPI). Image processing and phenotype recognition (CD8 + T cells, CK -CD8 +; CD8 + T bys, CK -CD8 +CD103 -) were performed using inFrom software, and automatic quantitative cell density analysis was conducted using R language. Differences in CD8 + T and CD8 + T bys densities at IM and TC were analyzed using the Mann-Whitney U test. The relationship between CD8 + T, CD8 + T bys and clinicopathological features was examined using the Kruskal-Wallis H test. The impact of CD8 + T and CD8 + T bys on recurrence-free survival (RFS) was evaluated using Kaplan-Meier, log-rank, and Cox proportional hazards models. Results:A total of 173 patients with stage ⅠA-ⅡA NSCLC were included, with a recurrence rate of 26.6% (46/173) and a median RFS of 62.3 months (range: 44.7-71.9 months). CD8 + T and CD8 + T bys densities (1/1 000) were significantly higher in the IM region than in the TC region [70(32, 155) vs. 37(18, 88), P＜0.001; 25(11, 46) vs. 18(7, 34), P=0.002]. No significant association was found between CD8 + T, CD8 + T bys and age, gender, smoking history, histological type, or pathological stage (all P＞0.05). Patients with low-density IM CD8 + T cells had lower RFS compared to those with high-density IM CD8 + T cells ( P=0.021; median RFS not reached), Further analysis revealed that patients with low-density IM CD8 + T bys cell had lower RFS compared to those with high-density IM CD8 + T bys ( P=0.047; median RFS not reached), and low-density IM CD8 + T cell was an independent risk factor for postoperative recurrence ( HR=1.836, 95% CI:1.007-3.347, P=0.048). Joint analysis of IM and TC revealed that patients with low IM CD8 + T bys and high TC CD8 + T bys had significantly lower RFS compared to the other three groups ( P=0.006), and this combination was an independent risk factor for postoperative recurrence in early-stage NSCLC ( HR=2.090, 95% CI:1.162-3.760, P=0.014). Conclusions:The spatial distribution of bystander CD8 + T cells within the primary tumor influences the prognosis of patients with early-stage NSCLC. Patients with low-density IM CD8 + T bys and high-density TC CD8 + T bys are more prone to recurrence after radical surgery.
