Tissue oxidative stress and expression of chicken UCP and ANT mRNA in laying hens exposed to acute cold stress.

1. Exposure to stress alters normal homoeostasis and, hence, the antioxidant defence system. The aim of this study was to examine the effect of acute cold temperature on the antioxidant defence system in hens.2. Hy-line grey commercial layers (80 40-week-old) were randomly assigned to one of eight groups. In groups 1 to 5, hens were exposed to low temperature at -8.68°C (cool stressed) for 2, 4, 6, 8 and 10 h, respectively. In groups 6 and 7, post 10 h cool stressed, hens were quickly transferred to room at 21°C to recovery for 2 h and 4h, respectively. In treatment groups 6 and 7, post 10 h cool stressed, hens were quickly transferred to room at 21°C for 2 h and 4 h, respectively. Group 8 was the control, where hens were housed under regular condition at 21°C as controls.3. Antioxidant enzymes (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GPx) and malondialdehyde (MDA), in skeletal muscle, the kidney, liver and pancreas were measured. The transcription of avUCP and ANT mRNA was tested by RT-PCR.4. The T-AOC activity was increased in the skeletal muscle of hens cold stressed for 2, 4, 6, 8 and 10 h and the 2 h recovery groups compared with control hens (p < 0.05). The GPx activity was increased in the liver and skeletal muscle after cold stress 4 h and in the pancreas of cold stress 2 h compared with the control group (p < 0.05). Antioxidant SOD activity was increased in the kidney after cold stress 6 h and in the liver after cold stress 10 h compared to the control group (p < 0.05). Measured MDA activity was increased in the pancreas after 2 h cold stress (p < 0.05).5. UCP mRNA expression level was increased in the pectoral muscle for 2 h and 4 h recovery groups compared with the control hens (p < 0.05) and avian uncoupling protein (UPC), adenine nucleotide translocator (ANT) expression level was increased in the leg muscle of hens cold stress for 2, 6, 8 h and recovery 2 and 4 h.6. The observed changes in the antioxidant defence system were tissue specific. Increments in levels of ANT (leg muscle) and UCP (pectoral and leg muscle) mRNA expression may be involved in the regulation of thermogenesis in skeletal muscle.

[Clinical features and long-term prognostic analysis of relapsed pediatric acute lymphoblastic leukemia].

Objective: To investigate the clinical characteristics and long-term prognostic factors of relapsed pediatric acute lymphoblastic leukemia (ALL). Methods: Clinical data including the age, time from initial diagnosis to relapse, relapse site, and molecular biological features of 217 relapsed ALL children primarily treated by the Chinese Children's Leukemia Group (CCLG)-ALL 2008 protocol in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences between April 2008 and April 2015 were collected and analyzed in this retrospective cohort study. Kaplan-Meier analysis was used to evaluate the overall survival (OS) rate and event free survival (EFS) rate for univariate analysis, and Cox proportional-hazards regression model was used to evaluate the influencing factors of OS rate and EFS rate for multivariate analysis. Results: The age at initial diagnosis of 217 relapsed patients was 5 (3, 7) years. There were 135 males and 82 females. The time from initial diagnosis to relapse of 217 children was 22 (10, 39) months. After relapse, 136 out of 217 children (62.7%) received treatment and the follow-up time was 65 (47, 90) months. The 5-year OS rate and EFS rate of the 136 relapsed children were (37±4) % and (26±4) %, respectively. The predicted 10-year OS rate and EFS rate were (35±5) % and (20±4) %, respectively. Univariate analysis showed that the 5-year OS rate in the group of patients with late relapse (43 cases) was significantly higher than those with very early (54 cases) and early relapse (39 cases) ((72±7)% vs. (16±5)%, (28±8)%, χ2=35.91, P<0.05), 5-year OS rate of the isolated extramedullary relapse group (20 cases) was significantly higher than isolated bone marrow relapse group (102 cases) and combined relapse group (14 cases) ((69±11)% vs. (31±5)%, (29±12)%, χ2=9.14, P<0.05), 5-year OS rate of high-risk group (80 cases) was significantly lower than standard-risk group (10 cases) and intermediate-risk group (46 cases) ((20±5)% vs. (90±10)%, (54±8)%, χ2=32.88, P<0.05). ETV6::RUNX1 was the most common fusion gene (13.2%, 18/136). The predicted 10-year OS rate of relapsed children with positive ETV6::RUNX1 was significantly higher than those without ETV6::RUNX1 (118 cases) ((83±9)% vs. (26±5)%, χ2=14.04, P<0.05). The 5-year OS for those accepted hematopoietic stem cell transplantation (HSCT) after relapse (42 cases) was higher than those without HSCT (94 cases) ((56±8)% vs. (27±5)%, χ2=15.18, P<0.05). Multivariate analysis identified very early/early relapse (HR=3.91, 95%CI 1.96-7.79; HR=4.15, 95%CI 1.99-8.67), bone marrow relapse including isolated bone marrow relapse and combined relapse (HR=6.50, 95%CI 2.58-16.34; HR=5.19, 95%CI 1.78-15.16), with ETV6::RUNX1 (HR=0.23, 95%CI 0.07-0.74) and HSCT after relapse (HR=0.24, 95%CI 0.14-0.43) as independent prognostic factors for OS (all P<0.05). Conclusions: Relapsed pediatric ALL mainly occurs very early and often affects bone marrow, which confer poor outcome. ETV6::RUNX1 is the most common genetic aberration with a favorable outcome. HSCT could rescue the outcome of relapsed children, though the survival rate is still poor.

[Relationship between epilepsy and patent foramen ovale].

This study aimed to investigate the prevalence and clinical characteristics of epilepsy in patients with patent foramen ovale (PFO) and the effect of PFO closure on seizures. Patients diagnosed with PFO were recruited and underwent brain magnetic resonance imaging, electrocardiography, transesophageal echocardiography, and transthoracic echocardiography with right ventriculography. In patients with epilepsy, electroencephalography was performed. A total of 110 patients completed the assessment. A chief complaint of chest tightness or palpitations was proportionately higher in patients aged<18 years, whereas headaches and seizures were higher in patients aged≥18 years (χ2=4.69,P<0.05). Comorbid epilepsy was observed in 20.9% of patients with PFO. The age at admission in the epileptic group (14-66(27±14)years) was significantly lower than that in the non-epileptic group (16-81(38±21)years) and that in patients with headache as the chief complaint (16-68(39±12)years) (t=3.29, P<0.05). The multivariate analysis found no risk factors related to the prognosis of epilepsy. The incidence of epilepsy was significantly higher in patients with PFO than in the general population.

[Clinical outcomes of allogeneic hematopoietic stem cell transplantation from matched sibling donor for myelofibrosis].

Objective: To evaluate the efficacy and safety of matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of myelofibrosis (MF). Methods: In this case series, the clinical data of 18 patients with MF who received allo-HSCT in the Department of Hematology, Peking University People's Hospital from December 2008 to December 2023 were retrospectively studied. Kaplan-Meier survival analysis and competitive risk model were used to evaluate the probabilities of 3-year overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR), and transplant related mortality (TRM). The transplant related complications were also analyzed. Results: Among the 18 patients included, there were 12 males and 6 females, with a median age of 50 (range: 28-64) years. All 18 patients achieved neutrophil engraftment, and the time of neutrophil engraftment [M (Q1, Q3)] was 16.0 (11.8, 18.0) days. Twelve patients achieved platelet engraftment, and the platelet engraftment time was 21.0 (16.2, 43.2) days. Six patients had grade Ⅱ to Ⅳ acute graft-versus-host disease (GVHD), and six patients had chronic GVHD. The 3-year OS rate and DFS rate after transplantation were 62.2% and 52.2%, respectively. The 3-year CIR and TRM were 29.7% and 24.6%, respectively. Four patients died during follow-up, with the main cause of death being infections. Conclusion: Matched sibling allo-HSCT is a feasible option for the treatment of MF.

Periodontitis and Diabetes Differentially Affect Inflammation in Obesity.

Periodontitis (PD) potentiates systemic inflammatory diseases and fuels a feed-forward loop of pathogenic inflammation in obesity and type 2 diabetes (T2D). Published work in this area often conflates obesity with obesity-associated T2D; thus, it remains unclear whether PD similarly affects the inflammatory profiles of these 2 distinct systemic diseases. We collected peripheral blood mononuclear cells (PBMCs) from cross-sectionally recruited subjects to estimate the ability of PD to affect cytokine production in human obesity and/or T2D. We analyzed 2 major sources of systemic inflammation: T cells and myeloid cells. Bioplex quantitated cytokines secreted by PBMCs stimulated with T cell- or myeloid-targeting activators, and we combinatorially analyzed outcomes using partial least squares discriminant analysis. Our data show that PD significantly shifts peripheral T cell- and myeloid-generated inflammation in obesity. PD also changed myeloid- but not T cell-generated inflammation in T2D. T2D changed inflammation in samples from subjects with PD, and PD changed inflammation in samples from subjects with T2D, consistent with the bidirectional relationship of inflammation between these 2 conditions. PBMCs from T2D subjects with stage IV PD produced lower amounts of T cell and myeloid cytokines compared with PBMCs from T2D subjects with stage II to III PD. We conclude that PD and T2D affect systemic inflammation through overlapping but nonidentical mechanisms in obesity, indicating that characterizing both oral and metabolic status (beyond obesity) is critical for identifying mechanisms linking PD to systemic diseases such as obesity and T2D. The finding that stage IV PD cells generate fewer cytokines in T2D provides an explanation for the paradoxical findings that the immune system can appear activated or suppressed in PD, given that many studies do not report PD stage. Finally, our data indicate that a focus on multiple cellular sources of cytokines will be imperative to clinically address the systemic effects of PD in people with obesity.

[Clinical features of 20 cases with Pneumocystis jirovecii pneumonia after allogeneic hematopoietic stem cell transplantation].

This study included 20 patients with hematological diseases who developed Pneumocystis jirovecii pneumonia (PJP) after receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT) from April 2014 to October 2022 at Peking University People's Hospital. The 20 patients comprised 13 males (65.0% ) and seven females (35.0% ), with a median age of 34 (19-60) years. Eleven cases (55.0% ) of acute myeloid leukemia, four cases (20.0% ) of acute lymphocytic leukemia, two cases (10.0% ) of myelodysplastic syndrome, one case (5.0% ) of chronic myelomonocytic leukemia, one case (5.0% ) of non-Hodgkin lymphoma, and one case (5.0% ) of aplastic anemia were analyzed. Three cases (15.0% ) of HLA-identical sibling hematopoietic stem cell transplantation, three cases (15.0% ) of matched unrelated donor hematopoietic stem cell transplantation, and 14 cases (70.0% ) of haploid hematopoietic stem cell transplantation were identified. The median onset time of PJP was 353 (74-1121) days after transplantation. The clinical symptoms mainly included fever, cough, expectoration, and dyspnea. All patients presented signs of infection based on the CT scan, including bilateral diffuse ground-glass opacities, patchy shadows, and solid nodules. Nine patients (45.0% ) required respiratory support via nasal catheter oxygen inhalation, while seven patients (35.0% ) required ventilator-assisted breathing. Seven (35.0% ) severe infections and 13 (65.0% ) mild to moderate infections were recorded. Moreover, eight patients (40.0% ) were complicated with human cytomegalovirus infection, whereas two patients were complicated with EB virus infection. Furthermore, all 20 patients received treatment with compound sulfamethoxazole (standard dose, 11 cases; low dose, 9 cases). Furthermore, 19 patients survived and one patient died.

[Prognostic analysis of 8 patients with hepatic adenoma undergoing allogeneic hematopoietic stem cell transplantation].

Objective: To evaluate the safety of patients with hepatic adenoma undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: A retrospective analysis of the clinical characteristics and prognosis of eight patients with hepatic adenoma who underwent allo-HSCT in the Hematology Department of Peking University People's Hospital from January 2010 to March 2024 was conducted. Results: Of the eight patients who underwent allo-HSCT with hepatic adenoma, one patient was considered MDS-h transfusion-dependent and seven had aplastic anemia. The median age of the patients was 23 years (13-48 years). The median time from the diagnosis of AA or MDS to transplantation was 14 years (6-24 years), whereas the median time from taking androgens to diagnosing hepatic adenoma was 9 years (5-13 years). Six cases underwent haplo-HSCT, one case underwent matched unrelated donor HSCT, and one case underwent matched related donor HSCT. All patients achieved neutrophil engraftment at a median time of 11.5 days (11-20 days) and PLT engraftment within 60 days at a median of 19 days (10-37 days) after haplo-HSCT. Moreover, seven patients developed CMV anemia after transplantation, three patients had hemorrhagic cystitis, and two patients developed acute GVHD. During and after transplantation, eight patients did not show severe liver function damage or rupture of hepatic adenoma. In relation to imaging size, four patients showed varying degrees of reduction in hepatic adenoma size after transplantation, whereas four patients did not show significant changes in hepatic adenoma size after transplantation. The median follow-up time was 540.5 (30-2 989) days. Of the eight patients, six survived and two died. Furthermore, no direct correlation was observed between death and hepatic adenoma. Conclusion: Patients with hepatic adenomas undergoing allo-HSCT are not contraindications for transplantation, which will not increase transplant-related mortality.

[Clinical analysis of allogeneic hematopoietic cell transplantation in 9 patients with hematological malignancies complicated by Gilbert's syndrome].

From January 1, 2013, to March 1, 2024, nine patients with hematological malignancies complicated by Gilbert's syndrome in Peking University People's Hospital underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patients comprised seven male and two female cases, with a median age of 38 (13-60) years old. Among them, three cases were acute myeloid leukemia, three cases were acute lymphocytic leukemia, two cases were myelodysplastic syndrome, and one case was chronic myelomonocytic leukemia. None of the patients had viral hepatitis. Of the nine cases, seven cases received the Bu-Cy+ATG regimen, while the other two cases received the TBI-Cy+ATG regimen (Bu, busulfan; Cy, cyclophosphamide; ATG, antithymocyte immunoglobulin; and TBI, total body irradiation). All patients achieved neutrophil engraftment, and eight received platelet engraftment. The median total bilirubin level was 45.4 (22.5-71.2) µmol/L before transplantation and 22.0 (18.0-37.2) µmol/L on -1d of preconditioning. The total bilirubin level on +20d after the transplantation of eight patients decreased compared with the baseline level before transplantation. Moreover, one patient had a transient increase in the total bilirubin level on +5d after transplantation, which was considered to be attributed to the toxicity of Bu. No patients were complicated by hepatic veno-occlusive disease. The median follow-up time was 739 (42-2 491) days. During the follow-up period, one patient died of recurrence, and the remaining eight patients had disease-free survival events.

[Efficacy and safety of venetoclax combined with decitabine, modified HA regimen and DLI in the treatment of relapsed pediatric AML/MDS after allogeneic hematopoietic stem cell transplantation].

Objective: To investigate the efficacy and safety of venetoclax combined with the decitabine, cytarabine, and homoharringtonine (HHT) regimen and donor lymphocyte infusion (DLI) for the preventive and salvage therapy of pediatric acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) after allogeneic hematopoietic stem cell transplantation (HSCT) . Methods: A total of 29 relapsed pediatric/minimal residual disease-positive AML after HSCT were recruited at the Peking University Institute of Hematology from January 1, 2021, to June 1, 2023. They were treated with the above combination regimen and administered with DLI after 24-48 hours at the end of chemotherapy, and the treatment response and adverse reactions were regularly assessed. Results: The overall response rate (ORR) was 75.8%, CR rate was 88.9% (8/9) in the hematologic relapse group, and MRD negativity rate was 61.1% (11/18) in the MRD-positive group. The incidence of agranulocytosis, anemia, and thrombocytopenia with a classification above grade 3 were 100%, 82.7%, and 100%, respectively. The median time of the granulocyte deficiency period was 15 days. Acute graft-versus-host diseases (aGVHD) with a classification of grades Ⅲ-Ⅳ occurred in 11.1% of the patients after DLI, while moderate or severe cGVHD occurred in 7.4% of the patients. The single risk factor for ORR was MNC counts of less than 10×10(8)/kg, and the relapse occurred within 100 days. At a median follow-up of 406 days, the 1-year OS was 65%, and the 1-year OS was 57% in the group with no reaction (P=0.164) compared with 71% in the group who had an overall reaction. Conclusion: The combined regimen based on the DAC, VEN, and modified HA regimen showed a high response rate in the salvage therapy for pediatric AML after the relapse of HSCT. However, bridging to transplantation should be performed immediately after remission to result in a long survival rate.

[Progression and application of circulating tumor DNA in lymphoma].

Lymphomas are a highly heterogeneous group of tumors that are classified into several subtypes. The gold standard method for the molecular profiling of lymphoma is based on invasive lymph node or tissue biopsy. However, this method cannot accurately capture spatial tumor heterogeneity in each patient as well as systemic tumor invasion and tumor burden. Circulating tumor DNA (ctDNA) is an emerging and highly versatile biomarker that overcomes the basic limitations of imaging scanning and tissue biopsy; has the characteristics of being simple, rapid, and non-invasive; and has good specificity and high sensitivity. ctDNA testing has been applied to a variety of subtypes of lymphoma and has been used for somatic mutation genotyping, efficacy monitoring during treatment, detection of minimal residual disease, and the prediction of survival, which may help clinicians make better clinical decisions in the diagnosis and treatment of lymphoma patients. Furthermore, this study also aims to review the different methods of ctDNA analysis and describe the specific applications of ctDNA in different lymphoma subtypes.

Aptamer-based biotherapeutic conjugate for shear responsive release of Von Willebrand factor A1 domain.

Smart polymers that mimic and even surpass the functionality of natural responsive materials have been actively researched. This study explores the design and characterization of a Single-MOlecule-based material REsponsive to Shear (SMORES) for the targeted release of A1, the platelet binding domain of the blood clotting protein von Willebrand factor (VWF). Each SMORES construct employs an aptamer molecule as the flow transducer and a microparticle to sense and amplify the hydrodynamic force. Within the construct, the aptamer, ARC1172, undergoes conformational changes beyond a shear stress threshold, mimicking the shear-responsive behavior of VWF. This conformational alteration modulates the bioavailability of its target, the VWF-A1 domain, ultimately releasing it at elevated shear. Through optical tweezer-based single-molecule force measurement, ARC1172s role as a force transducer was assessed by examining its unfolding under constant pulling force. We also investigated its refolding rate as a function of force under varied relaxation periods. These analyses revealed a narrow range of threshold forces (3-7 pN) governing the transition between folded and unfolded states. We subsequently constructed the SMORES material by conjugating ARC1172 and a microbead, and immobilizing the other end of the aptamer on a substrate. Single-molecule flow experiments on immobilized SMORES constructs revealed a peak A1 domain release within a flow rate range of (40-70 µL min-1). A COMSOL Multiphysics model translated these flow rates to total forces of 3.10 pN-5.63 pN experienced by the aptamers, aligning with single-molecule force microscopy predictions. Evaluation under variable flow conditions showed a peak binding of A1 to the platelet glycoprotein Ib (GPIB) within the same force range, confirming released payload functionality. Building on knowledge of aptamer biomechanics, this study presents a new strategy to create shear-stimulated biomaterials based on single biomolecules.

THE RELATIONSHIP BETWEEN MENTAL HEALTH AND PHYSICAL ACTIVITY AMONG STUDENTS FROM A PRIVATE UNIVERSITY: A CROSS-SECTION STUDY.

Depression is being recognized worldwide as a serious public health problem. Health problems may affect a college student's quality. Project aims to analyze the effects of physical activity on anxiety and depression in university student. METHODS: This study employed cross-sectional, self-reported survey methodology. A sample of 2008 student completed a test that included social-demographic data, GAD-7, PHQ-9, IPAQ and EAT-26.GAD-7 was assessed using the anxiety questionnaire (range 0-21, with higher scores indicating more anxiety). PHQ-9 was assessed using the depression questionnaire (range 0-27, with higher scores indicating more depression). Physical activity was assessed using a short version of the International Physical Activity Questionnaire (IPAQ), which is divided into three levels: low, moderate and high levels of physical activity. Eating attitude test-26(EAT-26) is widely used screening instruments for disordered eating attitudes (Scores 20 or above was defined as disordered eating attitude). The data were analyzed by SPSS 20.0 system. RESULTS: There was no significant correlation between depression and anxiety symptoms and child in the family, parents are highly educated, single-parent family and parents are doctors or nurses and other medical staff. The experimental data suggested that mental health was significantly associated with the suffer from domestic or social violence, use cell phones and computers for fun time, low-intensity exercise, high-intensity exercise and eating disorder. CONCLUSION: The thesis concludes that the physical activity was significantly associated with mental health. It is necessary to take measures to reduce anxiety and depression in college students, to improve their understanding of the importance of healthy.

[Characteristics and correlated factors of preoperative sleep disorders in cardiac surgical patients].

Objective: To investigate the clinical characteristics and correlated factors of preoperative sleep disorders in patients undergoing various types of cardiac surgery. Methods: The data of patients at the Structural Heart Surgery Center of Beijing Anzhen Hospital, Capital Medical University, from April 2023 to February 2024 were retrospectively collected. Patients were categorized into five groups based on cardiac surgical diagnosis: coronary heart disease, valvular disease, large vessel disease, congenital heart disease, and others. Each group was further subdivided into normal sleep (NS) and sleep disorder (SD) groups based on the Pittsburgh Sleep Quality Index (PSQI) scores. Demographic information, cognitive function, psychiatric symptoms, and other relevant data were collected. Clinical characteristics were compared between groups, and factors associated with preoperative sleep disorders were analyzed using multivariate logistic regression. Results: A total of 1 016 patients aged (58.6±12.7) years were included in the study, including 701 males and 315 females. The incidence of SD was 45.6% (463/1 016). Multivariate logistic regression analysis showed that aging was a risk factor for sleep disorders in patients with coronary heart disease (OR=1.050, 95%CI: 1.026-1.077) and valvular disease (OR=1.033, 95%CI: 1.013-1.053). High Self-rating Depression Scale (SDS) score was a risk factor for sleep disorders in patients with valvular disease (OR=1.050, 95%CI: 1.013-1.091). High score on the Montreal Cognitive Assessment (MoCA) subitem-abstraction ability was a protective factor for sleep disorders in patients with coronary heart disease (OR=0.695, 95%CI: 0.490-0.981). Conclusions: The risk factors of preoperative sleep disorders in cardiac surgery patients vary based on the type of cardiac disease. Aging, depression and abstraction ability correlate with sleep disorders in cardiac surgical patients.

[Survival status and influencing factors of death risk of HIV-infected patients in Hangzhou, 2004-2023].

Objective: To analyze the survival status and death factors of confirmed HIV-infected patients in Hangzhou to provide a basis for the formulation of AIDS prevention and treatment strategies. Methods: A retrospective cohort study was conducted. The data were from the HIV/AIDS Comprehensive Response Information Management System of the Chinese Disease Control and Prevention Information System.Epidemiological characteristics of HIV-infected patients were comparied in Hangzhou City from 2004 to 2023 by using chi-square Test. The survival rate of HIV-infected patients in Hangzhou was calculated by the life table method, the survival curves of different subgroups were described by the Kaplan-Meier method, and the Cox proportional hazard regression model was used to analyze the influencing factors of death risk. The SPSS 26.0 software was used for statistical analysis. Results: Among the 9 457 subjects, the total follow-up time was 58 004.18 person-years, 494 patients died, fatality rate of all-cause cases was 0.85 per 100 person-years.The average survival time was 18.59 (95%CI:18.40-18.78) years. Malignant neoplasms and pneumocystis pneumonia were the first (14.37%,71/494) and second (10.73%, 53/494) causes of death, respectively. Death within 6 months after diagnosis accounted for 42.51% (210/494), and suicide accounted for 4.25% (21/494). Multivariate Cox regression analysis showed that compared with those who received antiviral treatment (ART) within 3 months of diagnosis, those who received ART outside 3 months and those who did not receive ART had a 1.65 (95%CI:1.25-2.19) and 20.68 (95%CI:15.80-27.06) times risk of death, respectively. The HIV-infected patients with high CD4+T lymphocytes (CD4) counts for the first time had a lower risk of death. The risk of death of patients with baseline CD4 counts of 200-349 cells/µl, 350-499 cells/µl, and ≥500 cells/µl was 0.38 (95%CI:0.29-0.49), 0.26 (95%CI:0.19-0.36), 0.21 (95%CI:0.14-0.31) times higher than that of baseline CD4 counts <200 cells/µl, respectively. Conclusions: The overall survival of the HIV-infected patients was good in Hangzhou from 2004 to 2023. Early detection of HIV infection and timely mobilization to participate in ART was the key to improving the survival rate of patients. At the same time, given the suicide problem of HIV-infected patients, suicide surveillance and depression and anxiety screening of HIV-infected patients should be further strengthened, and targeted psychological intervention policies should be implemented.

[Pulmonary sarcomatoid carcinoma:report of three cases].

Pulmonary sarcomatoid carcinoma (PSC) is a rare disease with strong aggressiveness, low response rates to treatment, short survival span and poor prognosis, belonging to a group of non-small cell lung carcinomas (NSCLC) that remains incompletely understood. Here, we presented three PSC cases with epidermal growth factor receptor (EGFR) L858R, BRAF V600E and ALK mutations respectively, described their clinical characteristics and conducted a review of literature, in order to improve its therapeutic level, which also provided evidence-based medical evidence for driver gene screening and molecular targeted drug application in PSC patients.
