ObjectiveTo observe the prevention and control effect of processed Polygonatum cyrtonema on depression induced by chronic unpredictable mild stress （CUMS） in female rats. MethodsForty rats were assigned into control， model， and low-， medium-， and high-dose processed P. cyrtonema groups according to the random number table method， with 8 rats in each group. The rat model of depression was established with the CUMS method. The body mass， open field test， forced swimming test， Morris water maze test， levels of neurotransmitters ［dopamine （DA）， 5-hydroxytryptamine （5-TH）， and acetylcholine （ACh）］， serum levels of sex hormones ［gonadotropin-releasing hormone（GnRH）， testosterone （T）， and estradiol （E₂）］ and inflammatory factors ［tumor necrosis factor-α （TNF-α）， interleukin （IL）-6， and IL-10］， and mRNA and protein levels of factors in the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TRKB）/cAMP-response element binding protein （CREB） pathway were employed to evaluate the effect of processed P. cyrtonema on the CUMS-induced depression in female rats. ResultsThe body mass， open field test results， and forced swimming test results showed that the rat model of depression was successfully established. The comparison of behaviors， neurotransmitters， sex hormones， inflammatory factors， and neural pathways among groups showed that processed P. cyrtonema had different effects of preventing the development of depression in female rats. SPSS 25 was used for statistical analysis of error and significance. T test was conducted between groups. Each treatment group showed significant therapeutic effect compared with the model group （P<0.05）. Processed P. cyrtonema elevated the level of 5-TH （P<0.01） and lowered the levels of DA and ACh （P<0.01） in the brain tissue of female rats. In addition， it reduced the serum levels of GnRH， T， E₂， TNF-α， and IL-6 （P<0.05） and up-regulated the mRNA levels of BDNF and TRKB in the rat brain. ConclusionProcessed P. cyrtonema has a non-hyperactive preventive effect on CUMS-induced depression in rats， which provides a theoretical basis for the development of processed P. cyrtonema as a functional food product.

Liumotang comes from the Yuan dynasty's Effective Prescription Handed Down for Generations of Physicians. It is composed of six medicinal materials： Arecae Semen， Aquilariae Lignum Resinatum， Aucklandiae Radix， Linderae Radix， Rhei Radix et Rhizoma， and Aurantii Fructus. It is a classical formula for treating abdominal pain due to Qi stagnation and constipation accompanied by heat. This study systematically collated the records of Liumotang in ancient medical books and modern clinical literature and conducted in-depth analysis and textual research on its formula source， main diseases， composition， dosage， medical books， container capacity， processing， preparation method， usage， drug basis， formula meaning， and other key information， so as to provide a powerful reference for the development and clinical application of compound preparations of the classical formula Liumotang. The results show that Liumotang was first seen in Effective Prescription Handed Down for Generations of Physicians， and many medical books of the past dynasties have imitated this. In terms of drug basis， the dried and mature seeds of the palm plant Areca catechu， resin-containing wood of the Daphneaceae plant Aquilaria sinensis， the dried roots of the Asteraceae plant woody Aucklandia lappa， the dried tuber root of the Lauraceae plant Lindera aggregata， the dried roots and rhizomes of the knotweed plant， R. palmatum， R.tangutikum， and R. officinale， and the dried and unripe fruits of the citrus genus C. aurantium and its cultivated varieties from the family Rutaceae were selected. In terms of dosage， through the textual research on bowls in the Ming and Qing dynasties， combined with the conversion of medicines and bowl capacity in the Qing dynasty， it was estimated that the dosage of each drug in the Yuan dynasty was 10.86 g. In the Ming and Qing dynasties， the dosage of drugs was mostly equal， but the dosage of drugs was somewhat different. In terms of processing， preparation method， and usage， in the medical books of the past dynasties， the processing of drugs has slightly changed， but raw drugs are used in all preparations. The preparation method and usage did not change much during the Yuan， Ming， and Qing dynasties， except for certain differences in dosage. In terms of syndrome， Liumotang was first used to treat abdominal pain due to Qi stagnation and constipation accompanied by heat. Medical books of the past dynasties often omit the symptoms of heat. In modern clinical practice， Liumotang is mainly used in the digestive system and urinary system diseases and is mostly used to treat constipation-predominant irritable bowel syndrome， biliary reflux gastritis， functional constipation， slow transit constipation， and other diseases， with no adverse reactions found yet. The above results provide a reliable scientific basis for the development and clinical treatment of Liumotang compound preparations.

Objective To evaluate the survival outcomes of segmentectomy versus lobectomy for T1c non-small cell lung cancer (NSCLC). Methods We searched PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), CNKI (China National Knowledge Infrastructure), and Wanfang Data, with the search time limit set from the inception of the databases to February 2024. Three researchers independently screened the literature, extracted relevant information, and evaluated the risk of bias of the included literature according to the Newcastle-Ottawa Scale (NOS). Meta-analysis was conducted using STATA 15.1. Results A total of 8 retrospective cohort studies were included, involving 7 433 patients. The NOS scores of the included studies were all ≥7 points. Patients who underwent lobectomy had significantly higher five-year overall survival (OS) rates compared to those who underwent segmentectomy (adjusted HR=1.11, 95%CI 0.99-1.24, P=0.042). Compared with lobectomy, segmentectomy showed no significant difference in adjusted three-year OS rate (adjusted HR=0.88, 95%CI 0.62-1.24) and adjusted five-year lung cancer-specific survival (adjusted HR=1.10, 95%CI 0.80-1.51, P=0.556) of patients with T1c NSCLC. Moreover, there were no differences in the five-year adjusted relapse-free survival (adjusted HR=1.23, 95%CI 0.82-1.85, P=0.319), and adverse events (OR=0.57, 95%CI 0.37-0.90, P=0.015) in the segmentectomy group were significantly less than those in the lobectomy group. Subgroup analysis based on whether patients received neoadjuvant therapy showed that among studies that excluded patients who received neoadjuvant therapy, no significant difference in 5-year adjusted OS rate was observed between the segmentectomy group and lobectomy group (adjusted HR=1.02, 95%CI 0.81-1.28, P=0.870). Conclusion Segmentectomy and lobectomy show no significant difference in long-term survival in stage T1c NSCLC patients, with segmentectomy associated with fewer postoperative complications. Further high-quality research is needed to confirm the comparative efficacy and safety of lobectomy and segmentectomy for T1c NSCLC patients.

Objective To analyze the economic cost of self-monitoring of gestational diabetes mellitus, and provide a basis for measuring the economic burden of gestational diabetes mellitus, and to provide a reference for the formulation of intervention development and the adjustment of resource allocation. Methods The individual economic cost of self-monitoring for gestational diabetes mellitus was measured based on a decision tree model, and the total economic cost of self-monitoring for gestational diabetes mellitus in Beijing was estimated. The uncertainty of the model parameters was analyzed using one-way sensitivity analysis. Results The average individual economic cost of gestational diabetes self-monitoring was 1184 RMB, and the individual cost incurred by choosing different types of blood glucose meters ranged from 403 to 18 000 RMB. The average individual economic cost of finger-stick blood glucose monitoring was 606 RMB and the average individual economic cost of continuous glucose monitoring was 2 374 RMB. The total economic cost of gestational diabetes self-monitoring in Beijing was 23.818 0 million RMB, and the total economic cost incurred by choosing different types of blood glucose meters ranged from 0.292 5 to 9.027 9 million RMB. The proportion of the finger-stick blood glucose monitoring had the greatest impact on the robustness of the results. Conclusion Finger-stick blood glucose monitoring is still the dominant self-monitoring method and is less costly than continuous glucose monitoring. Self-monitoring of pregnant women with gestational diabetes mellitus incurs certain economic cost and causes an economic burden on society.

Myelodysplastic syndrome (MDS), a myeloid tumor derived from the malignant clones of hematopoietic stem cells, has an annually increasing incidence. The contemporary research direction has shifted to analyzing the synergistic effect of immune surveillance collapse and abnormal bone marrow microenvironment in the pathological process of MDS. Against this backdrop, the immune checkpoint molecule TIM3 has emerged as a key target because of its persistently high expression on the surface of important immune cells such as T and NK cells. The abnormal activation of the TIM3 pathway is the mechanism by which solid tumors and hematological malignancies achieve immune escape and is a key hub in the formation of immune exhaustion phenotypes. This work integrates the original discoveries of our team with the latest international progress, systematically demonstrating the bidirectional regulatory network of TIM3 between the malignant clone proliferation of MDS and the immunosuppressive microenvironment. Integrating the evidence from emerging clinical trials allows us to consider the clinical significance of TIM3-targeted blocking for MDS, providing a transformative path to overcome the resistance of traditional treatments and marking a new chapter in the active immune reconstitution of MDS treatment.

Objective This study was performed to establish and compare guinea pig models of tuberculosis using intranasal and aerosol infection routes at different doses.The overall goal was to provide a foundation for establishing a standardized guinea pig model of tuberculosis for the study of respiratory tract infection.Methods Twenty-four female guinea pigs were randomly divided into six groups of four guinea pigs each.They were then infected with two doses of Mycobacterium tuberculosis through either the aerosol route(groups A,B,and C)or intranasal route(groups D,E,and F).Aerosol infection groups consist of 3 groups:group A(Aerosol control group,uninfected control group),group B(Aerosol low-dose group,5×102 CFU),and group C(Aerosol high-dose group,5×103 CFU)Intranasal infection groups also consist of 3 groups:group D(Intranasal control group,uninfected control group),group E(Intranasal low-dose group,1×104 CFU),and group F(Intranasal high-dose group,5×104 CFU).The clinical manifestations of the guinea pigs were observed after infection.All guinea pigs were euthanized on day 14.Lung,spleen,and liver tissues were obtained for gross examination and histopathological analysis using hematoxylin-eosin staining to identify characteristic lesions associated with tuberculosis.Acid-fast staining was performed on in situ tissues and organs followed by bacterial culture to analyze the bacterial load.Results The guinea pigs in four infection groups(B,C,E,and F)exhibited macroscopic tuberculosis lesions in the lung,spleen,and liver.Histopathological examination revealed the presence of tuberculous granuloma lesions.Acid-fast staining and bacterial load analysis demonstrated that the bacteria were primarily localized in the lung tissue of aerosol-infected groups B and C,with a few also present in the spleen and liver,and the bacterial load was 104～105 CFU/mL.In intranasal infection groups E and F,bacteria were found in the lung,spleen,and liver with a similar bacterial load of 104～105 CFU/mL.There was no significant difference in lesion severity or bacterial load among groups B,C,E,and F;however,groups B,C,and F showed low standard deviations for both pathology and etiology.Conclusions A guinea pig model of acute tuberculosis was successfully established using two doses administered through distinct routes of infection.Pathological examination and pathogenic analysis demonstrated that an aerosol dose of 5×102 CFU of Mtb effectively established a homogeneous model of acute tuberculosis with good consistency among the animals.Additionally,intranasal infection with 5×104 CFU of Mtb produced a relatively uniform model of tuberculosis.Notably,however,aerosol infection at 5×102 CFU progressed to an acute tuberculosis model more rapidly than intranasal infection at 5×104 CFU.

Objective To explore the influence of perfectionism on work immersion of clinical nurses, and to analyze the roles of perceived stress and social connection in the relationship between perfectionism and work immersion. Methods A total of 646 clinical nurses from three tertiary-A hospitals in Guangzhou City were selected as the research subjects using the convenience sampling method. The perfectionism, perceived stress, social connectedness, and work immersion of clinical nurses were assessed using the Chinese version of the Frost Multidimensional Perfectionism Scale, Perceived Stress Scale, Social Connectedness Scale and Work Immersion Scale. Results The average scores for perfectionism, perceived stress, social connectedness, and work immersion among the clinical nurses were (80.3±12.6), (42.5±8.3), (88.1±16.8), and (42.5±8.3) points, respectively. Perceived stress partially mediated the relationship between perfectionism and work immersion, with an effect value of 0.06 and 95% confidence interval (CI) of (0.027-0.096), accounting for 21.6% of the total effect. Social connectedness moderated the initial path and direct path which perfectionism affected work immersion [standardized partial regression coefficients were -0.15 and 0.21, and 95%CI were (-0.210--0.082 ) and (0.140-0.281), respectively, both P<0.01). Conclusion Perfectionism may directly or indirectly affect the work immersion of clinical nurses, and perceived stress plays a partial mediating role, while social connectedness acts as a moderator in this relationship

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

It was a single-center cross-sectional study to investigate the association of serum C3 level with blood pressure and estimated glomerular filtration rate (eGFR) in patients with idiopathic membranous nephropathy (IMN). The clinical and pathological data of 98 patients with IMN diagnosed by renal biopsy in the Department of Nephrology of East Hospital Affiliated to Tongji University from August 1, 2018 to October 31, 2023 were retrospectively analyzed. The demographic characteristics, serum complement C3 and other clinical data were compared between the non-hypertension group ( n=37) and hypertension group ( n=61). Pearson or Spearman correlation analysis method was used to analyze the correlation between serum C3 and eGFR in IMN patients and IMN patients with hypertension. Multiple linear regression analysis was used to analyze the related factors of eGFR in IMN patients with chronic kidney disease stage 1-3 in hypertension group. The results showed that compared with the non-hypertension group, the patients in hypertension group were older, and had higher levels of serum creatinine, cystatin C, urinary microalbumin to creatinine ratio, serum C3 and C4, and lower eGFR (all P<0.05). The correlation analysis showed that there was no correlation between serum C3 level and eGFR in IMN patients ( r=0.118, P=0.247). However, serum C3 level was positively correlated with eGFR in IMN patients with hypertension ( r=0.325, P=0.011). Multiple linear regression analysis showed that eGFR was negatively correlated with age ( β=-0.328, P=0.013), and positively correlated with serum C3 level ( β=0.228, P=0.048). The study shows that serum C3 level in hypertension group is higher than that in non-hypertension group in IMN patients. Moreover, serum C3 is positively correlated with eGFR.
