Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To investigate the predictive value of inflammatory cells and clinical features in the prognosis of immune checkpoint inhibitors (ICIs) treating non-small cell lung cancer (NSCLC).Methods The data of 163 cases of stage Ⅲ and Ⅳ NSCLC patients treated with the ICIs in this hospital from January 1,2017 to December 31,2022 were collected.The CT examination was conducted after 6-8 weeks treatment.The pa-tients were divided into the objective remission group[complete remission (CR)+partial remission (PR)]and non-objective remission group[stable disease (SD)+progressed disease (PD)],disease control group (CR+PR+SD) and non-disease control group (PD),persistent clinical benefit group (DCB) and non-DCB group.The differences in clinical features and inflammatory cells indicators were compared among the differ-ent groups.The receiver operating characteristic (ROC) curve was adopted to evaluate the predictive efficiency of the inflammatory cells indicators for DCB.The influencing factors analysis of progression free survival (PFS) time and overall survival (OS) time adopted the Cox regression analysis.Results The lymphocyte count (ALC) in the disease control group was higher than that in the non-disease control group.The neutro-phil to lymphocyte ratio (NLR),platelet-lymphocyte ratio (PLR) and mononuclear lymphocyte ratio (MLR) were lower than those in the non-disease control group.The proportions of squamous cell carcinoma,stage Ⅲ,ECOG score 0-1 point,adverse reactions in the DCB group were higher than those in the non-DCB group (P<0.05),the PLT count,NLR,PLR and MLR were lower than those in the non-DCB group (P<0.05). The ROC curve analysis results showed that PLT,NLR,PLR and MLR could serve as the indicators for pre-dicting DCB,the area under of ROC curve (AUC) was 0.633,0.602,0.635 and 0.604 respectively,the opti-mal cut off values were 187×109/L (P=0.004),5.0 (P=0.026),235 (P=0.003) and 0.35 (P=0.024) re-spectively.The multivariate Cox regression analysis showed that non-squamous carcinoma including adenocar-cinoma (HR=1.565,95％CI:1.057-2.316) and other pathologic types (HR=2.285,95％CI:1.326-3.936),ECOG score 2-3 points (HR=2.375,95％CI:1.652-3.415),AMC≥0.65×109/L (HR=1.847,95％CI:1.160-2.938) and PLR≥235 (HR=1.557,95％CI:1.016-2.386) were the independent risk factors for short PFS.The ECOG score 2-3 points (HR=4.615,95％CI:2.882-7.391),AMC≥0.65×109/L (HR=5.161,95％CI:2.984-8.925) and PLR ≥235 (HR=1.732,95％CI:1.059-2.833) were the independent risk fac-tors for short OS (P<0.05),and having adverse reactions (HR=0.472,95％CI:0.294-0.757) was the independ-ent protective factor for short OS (P<0.05).Conclusion Lower PLT,AMC,NLR,MLR and PLR,higher ALC,squamous cell carcinoma,TNM stage Ⅲ,ECOG score 0-1 point and immunotherapy related adverse reactions could prompt that the prognosis is good in ICIs treating advanced NSCLC.PLT,NLR,PLR and MLR could serve as the indicators for predicting DCB.

Retinopathy of prematurity(ROP), an abnormal vascular proliferative retinopathy of prematurity, is a serious condition that can lead to retinal detachment or blindness. With the development of neonatal medicine, the survival rate of low birth weight and low gestational age infants has been increasing, as well as the incidence of ROP. Therefore, studying ROP's pathogenesis and influencing factors is of great clinical importance. Numerous studies have been conducted on the risk factors for ROP, including gestational age, oxygen intake, mode of delivery, neonatal bronchopulmonary dysplasia, and the use of surfactants. At present, it is widely accepted both at home and abroad that preterm birth, low birth weight, and high oxygen concentration after birth are independent risk factors for ROP. In recent years, more and more scholars have found that abnormalities in blood indicators in preterm infants may be associated with the development of ROP. This article reviews the effects of platelets, haemoglobin, blood glucose, inflammatory cells, and lipids on ROP, providing a reference for identifying and preventing risk factors for ROP.

Meibomian gland dysfunction is a chronic and diffuse disease of the meibomian glands, characterized by obstruction and(or)abnormal secretion of the terminal ducts. Clinically, it can lead to tear film abnormalities and inflammation of the ocular surface, resulting in symptoms of ocular irritation and potential corneal damage that may impact visual function. Meibomian gland dysfunction can be classified into two types based on meibomian gland secretion: low secretion type and high secretion type. The low secretion type further includes acinar atrophy type and obstruction type. In recent years, research has revealed that patients with diabetes experience chronic damage to their meibomian gland tissue in the early stages of the disease, leading to structural and functional changes. The incidence and severity of meibomian gland dysfunction are higher in diabetic patients. However, there are numerous complex factors contributing to this condition in diabetes patients, and mechanisms remain unclear at present. This article reviews both domestic and international research progress on the pathological mechanism underlying meibomian gland dysfunction in diabetes.

Objective To investigate the effects of an adeno-associated virus(AAV2)vector expressing secretory transforming growth factor-β(TGF-β)type Ⅱ receptor(sTβRⅡ)extracellular domain-IgG2a Fc fusion protein(sTβRⅡ-Fc)on proliferation and migration of triple-negative murine breast cancer 4T1 cells in mice.Methods The pAAV-sTβRⅡ-Fc vector expressing sTβRⅡ-Fc fusion protein constructed by molecular cloning,the capsid protein-expressing vector pAAV2 and the helper vector were co-transfected into HEK 293T cells to prepare the recombinant AAV2-sTβRⅡ virus,which was purified by density gradient centrifugation with iodixanol.Western blotting was used to examine the effects of AAV-sTβRⅡ virus on Smad2/3 phosphorylation in 4T1 cells and on expression levels of E-cadherin,vimentin and p-Smad2/3 in 4T1 cell xenografts in mice.BALB/c mice bearing subcutaneous xenografts of luciferase-expressing 4T1 cells received intravenous injections of AAV-sTβRⅡ virus,AAV-GFP virus or PBS(n=6)through the tail vein,and the proliferation and migration of 4T1 cells were analyzed with in vivo imaging.Ki67 expression in the tumor tissues and sTβRⅡ protein expressions in mouse livers were detected with immunohistochemistry and immunofluorescence staining,and tumor metastases in the vital organs were examined with HE staining.Results The recombinant pAAV-sTβRⅡ-Fc vector successfully expressed sTβRⅡ in HEK 293T cells.Infection with AAV2-sTβRⅡ virus significantly reduced TGF-β1-induced Smad2/3 phosphorylation in 4T1 cells and effectively inhibited proliferation and lung metastasis of 4T1 xenografts in mice(P<0.05).In the tumor-bearing mice,intravenous injection of AAV-sTβRⅡ virus significantly increased E-cadherin expression,reduced vimentin and Ki67 protein expressions and Smad2/3 phosphorylation level in the tumor tissues(P<0.05 or 0.01),and induced liver-specific sTβRⅡ expression without causing body weight loss or heart,liver,spleen or kidney pathologies.Conclusion The recombinant AVV2 vector encoding sTβRⅡ extracellular domain is capable of blocking the TGF-β signaling pathway to inhibit the proliferation and lung metastasis of 4T1 cells in mice.
