Objective To explore the effect of salidroside(Sal)on endoplasmic reticulum stress and connexin 43 in rats with myocardial ischemia-reperfusion injury(MIRI).Methods SD rats were randomly divided into Sham group,MIRI group,low-does Sal(Sal-L)group and high-does Sal(Sal-H)group.The Sham group and MIRI group were intraperitoneal injec-ted with 0.9％sodium chloride solution(10 mL·kg-1·d-1),the Sal-L group and Sal-H group were intraperitoneal injected at a volume of 10 mL·kg-1 with Sal(12,36 mg·kg-1·d-1),respectively.Each group was given a corresponding intervention once a day for 3 d.The MIRI model was established 30 min after the last administration in all groups except the Sham group.The patho-logical changes of myocardial tissue were observed by Hematoxylin-eosin(HE)staining.TdT-mediated-dUTP nick end labeling(TUNEL)was used to observe the apoptosis of cardiomyocyte,the genes and proteins expression of Cx43 and endoplasmic reticu-lum stress related factors such as GRP78,Caspasel2,CHOP and so on were detected by quantitative real-time polymerase chain reaction(q-PCR)and western blot analysis.Results Compared with the MIRI group,the degree of tissue and cell injury in each Sal group was alleviated,with a decreased apoptosis rate observed in the Sal-H group(P＜0.05),the gene expression of Cx43 was up-regulated while GRP78,Caspase12,and CHOP gene expressions were down-regulated in both does groups of Sal.The protein expressions of Cx43 and GRP78 were also be up-regulated and down-regulated respectively in both dose groups of Sal,meanwhile the protein expressions of CHOP,Bax,Caspasel2 and cleaved-Caspase3 were down-regulated and the protein expres-sion of Bcl-2 was up-regulated in SAL-H group(P＜0.05).Conclusion The protective effect of salidroside on cardiomyocytes may be related to the inhibition of endoplasmic reticulum stress-induced apoptosis and the imbalance of Cx43 metabolism.

Objective To explore the impact of nursing intervention based on the information-motivation-behavioral skill(IMB)model on the acceptance of disability in stroke patients.Methods A total of 92 patients with first-onset stroke who were hospitalized at the Affiliated Hospital of Hangzhou Normal University from July 2022 to December 2023 were selected and divided into experimental group(47 cases)and control group(45 cases)according to the random number table method.The control group received routine care,while the experimental group received nursing intervention based on the IMB model in addition to routine care.The acceptance of disability and depression levels of two groups were compared.Results After the intervention,the acceptance of disability in experimental group was significantly higher than that in control group and increased over time(P＜0.05).The degree of depression in experimental group was significantly lower than that in control group and decreased over time(P＜0.05).Conclusion Nursing intervention based on the IMB model can enhance the acceptance of disability among stroke patients,reduce the degree of depression,and improve disease prognosis,demonstrating good clinical practical value.

This study aimed to evaluate the efficacy and safety of combining albumin-bound paclitaxel (abpaclitaxel) and anlotinib for ovarian cancer. In this study, 44 patients diagnosed with platinum-resistant ovarian cancer were enrolled. Patients received ab-paclitaxel along with anlotinib until disease progression or intolerable toxicity. Efficacy was assessed according to RECIST 1.1 criteria or Rustin's criteria. The primary endpoint was the investigator-evaluated objective response rate (ORR). 44 patients were enrolled between January 2021 and March 2023 with a median age of 49 years. Twenty-nine had measurable lesions and 15 had non-measurable lesions. Overall, the investigator-evaluated ORR was 56.8% (25/44; 95% CI 0.411-0.713) in intention-to-treat population and 58.1% (25/43; 95% CI 0.422-0.726) in per-protocol population. The median progression-free survival was 9.8 months, and the median duration of response was 7.4 months. For safety, grade 3/4 adverse events (AEs) included leukopenia, gum pain, hypertension, and hand-foot syndrome. The response rates were 55.0% (11/20) in patients with previous use of antiangiogenic reagents and who had previous use of PARP inhibitors. The combination of ab-paclitaxel and anlotinib showed promising anti-tumor activity and a manageable safety profile in platinum-resistant ovarian cancer. Patients with previous use of antiangiogenic drugs or PARP inhibitors still benefited from this protocol.

Objective: To understand the status and related factors of knowledge, attitude and practice (KAP) on vision health among young children s parents in Bao an District, Shenzhen, so as to provide reference for further controlling myopia and promoting children s visual health. Methods: From May 16th to 26th, 2024, a stratified cluster random sampling method was used to conduct an online questionnaire survey on 7 666 parents of kindergarten children across 41 kindergartens in a street of Bao an District, Shenzhen. The t-test, variance analysis and multiple linear regression analysis were used to analyze the related factors of KAP on vision health among children s parents. Results: The pass rates of parental vision KAP and overall assessment were 25.10%, 98.49 %, 71.18% and 58.26%, respectively. The results of the multiple linear regression analysis showed that only fathers with myopia, only mothers with myopia, both parents with myopia, children in the bottom classes, middle classes, senior classes, and pre school had higher standardized scores for KAP on vision health among parents ( β=0.08, 0.11, 0.16, 0.17, 0.16, 0.16, 0.05, P <0.05), compared to both parents without myopia and children in daycare classes. Parents of young children with myopia, and who didn t know their children s visual acuity and their own visual acuity had a lower KAP standardized scores ( β=-0.02, -0.04, -0.05 , P< 0.05). Conclusions Young children s parents in Bao an District hold a positive attitude towards vision health, but are lack of knowledge and practice. It is imperative to transmit accurate information and concepts about children s vision health to parents in a targeted manner. In particular, knowledge and guidance should be strengthened for children s parents.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH) are both chronic progressive respiratory diseases that cannot be completely cured. COPD is characterized by irreversible airflow limitation, chronic airway inflammation, and gradual decline in lung function, whereas PH is characterized by pulmonary vasoconstriction, remodeling, and infiltration of inflammatory cells. These diseases have similar pathological features, such as vascular hyperplasia, arteriolar contraction, and inflammatory infiltration. Despite these well-documented observations, the exact mechanisms underlying the occurrence and development of COPD and PH remain unclear. Evidence that mitochondrial dynamics imbalance is one major factor in the development of COPD and PH. Mitochondrial dynamics is precisely regulated by mitochondrial fusion proteins and fission proteins. When mitochondrial dynamics equilibrium is disrupted, it causes mitochondrial and even cell morphological dysfunction. Mitochondrial dynamics participates in various pathological processes for heart and lung disease. Mitochondrial dynamics may be different in the early and late stages of COPD and PH. In the early stages of the disease, mitochondrial fusion increases, inhibiting fission, and thereby compensatorily increasing adenosine triphosphate (ATP) production. With the development of the disease, mitochondria decompensation causes excessive fission. Mitochondrial dynamics is involved in the development of COPD and PH in a spatiotemporal manner. Based on this understanding, treatment strategies for mitochondrial dynamics abnormalities may be different at different stages of COPD and PH disease. This article will provide new ideas for the potential treatment of related diseases.

Primary central nervous system lymphoma (PCNSL) is a highly aggressive malignant lymphoma. As most chemotherapy drugs have difficulty in crossing the blood-brain barrier, PCNSL shows a difficulty in clinical treatment, a high recurrence rate and a poor prognosis. Early identification of relapsed patients and prompt initiation of salvage therapy play a critical role in the improvement of patients' prognosis. Brain biopsy is the gold standard to identify recurrence, while the risk of operation failure and complications is still high. Non-invasive imaging techniques are beneficial for early identification of recurrence in PCNSL and can provide an important basis for guiding relapsed patients to adjust treatment plans in time. However, there is no unified evaluation standard for imaging methods of monitoring the relapsed lesions of PCNSL. With the further research of the pathophysiological mechanism of PCNSL, biomarker detection has become a new method to identify recurrence and more clinical evidence is still needed in the future.
