BACKGROUND: Immune checkpoint inhibitors (ICIs) are increasingly used as first-line therapy for patients with advanced non-small cell lung cancer (NSCLC) harboring no actionable mutations; however, data on their efficacy among patients presenting with intracranial lesions are limited. This study aimed to explore the efficacy and safety of ICIs combined with chemotherapy in advanced NSCLC patients with measurable brain metastasis at initial diagnosis. METHODS: Our study retrospectively analyzed clinical data of a total of 211 patients diagnosed with driver gene mutation-negative advanced NSCLC with measurable, asymptomatic brain metastasis at baseline from Hunan Cancer Hospital between January 1, 2019 and September 30, 2021. The patients were stratified into two groups according to the first-line treatment regimen received: ICI combined with chemotherapy ( n = 102) or chemotherapy ( n = 109). Systemic and intracranial objective response rates (ORRs) and progression-free survival (PFS) were analyzed. Adverse events were also compared between the groups. RESULTS: Compared with the chemotherapy-based regimen, the ICI-containing regimen was associated with a significantly higher intracranial (44.1% [45/102] vs . 28.4% [31/109], χ2 = 5.620, P = 0.013) and systemic (49.0% [50/102] vs . 33.9% [37/109], χ2 = 4.942, P = 0.019) ORRs and longer intracranial (11.0 months vs . 7.0 months, P <0.001) and systemic (9.0 months vs . 5.0 months, P <0.001) PFS. Multivariable analysis consistently revealed an independent association between receiving ICI plus platinum-based chemotherapy as a first-line regimen and prolonged intracranial PFS (hazard ratio [HR] = 0.52, 95% confidence interval [CI]: 0.37-0.73, P <0.001) and systemic PFS (HR = 0.48, 95% CI: 0.35-0.66, P <0.001). No unexpected serious adverse effects were observed. CONCLUSION: Our study provides real-world clinical evidence that ICI combined with chemotherapy is a promising first-line treatment option for driver gene mutation-negative advanced NSCLC patients who present with brain metastasis at initial diagnosis.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

On February 2022, WHO released the evidence-based guideline on control and elimination of human schistosomiasis, with aims to guide the elimination of schistosomiasis as a public health problem in disease-endemic countries by 2030 and promote the interruption of schistosomiasis transmission across the world. Based on the One Health concept, six evidence-based recommendations were proposed in this guideline. This article aims to analyze the feasibility of key aspects of this guideline in Chinese national schistosomiasis control program and illustrate the significance to guide the future actions for Chinese national schistosomiasis control program. Currently, the One Health concept has been embodied in the Chinese national schistosomiasis control program. Based on this new WHO guideline, the following recommendations are proposed for the national schistosomiasis control program of China: (1) improving the systematic framework building, facilitating the agreement of the cross-sectoral consensus, and building a high-level leadership group; (2) optimizing the current human and livestock treatments in the national schistosomiasis control program of China; (3) developing highly sensitive and specific diagnostics and the framework for verifying elimination of schistosomiasis; (4) accelerating the progress towards elimination of schistosomiasis and other parasitic diseases through integrating the national control programs for other parasitic diseases.

Objective: To study the variation patterns of rhizospheric soil nutrient and the content of nutrient elements for Fritillaria taipaiensis,in order to provide the theoretical base for the soil improvement and balanced fertilization during the artificial cultivation. Method: Totally 14 samples of rhizospheric soil of Fritillaria taipaiensis from different origins and years were taken as the research objects. Total N,available N,total P,available P,total K,available K,organic matter,pH and 7 nutrient element contents (Ca,Mg,Na,Mn,Zn,Cu and Ni) were analyzed by the soil agrochemical analysis method combined with the atomic absorption spectrophotometry. SPSS 22.0 software was applied for data multiple comparison and correlation analysis. Result: The all results showed significant differences (P<0.05) and certain relative correlations between samples of different origins or years, and the rhizospheric soil nutrient or the content of nutrient elements of F. taipaiensis. The content of total N,available N,total P,available P and organic matter of rhizospheric soil collected from cultivated varieties decreased with the increase of years,and the content of total K,available K and pH decreased first and then increased. However,the soil physical and chemical properties of wild varieties had no obvious change with the increase of years. The content of Ca,Mg,Na and Cu of soil from cultivated varieties decreased with the increase of years,while the content of Mn decreased first and then increased. And Zn and Ni showed no significant change with the increase of years. Compared with cultivated varieties,the content of Ca,Mg,Na,Mn and Cu increased first and then decreased. The content of Zn and Ni showed no obvious change. In general,the rhizospheric soil nutrient and the content of nutrient elements for wild F. taipaiensis were superior to those of cultivated varieties. Conclusion: The third year is the turning point of F. taipaiensis growth. The rhizospheric soil nutrient and the content of nutrient elements decreased obviously after three years. Attention shall be given to the balanced fertilization,the improvement of soil quality and the prevention of the cropping during cultivation of F. taipaiensis.

OBJECTIVE: To observe the characteristics of carotid intima-media thickness (IMT) and cerebral blood flow velocity in patients with mild-to-moderate hypertension, and to evaluate the effects of acupuncture on carotid IMT and blood flow velocity of middle cerebral artery and vertebral-basilar artery. METHODS: A total of 240 patients with mild-to-moderate hypertension who met the inclusion criteria were treated with acupuncture method proposed by academician . The acupoints of Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3) were selected. The treatment was given once a day, five times a week for 3 months. The carotid ultrasonography and transcranial color Doppler were performed before treatment and 3 months after treatment to evaluate the improvements of carotid IMT and brain blood flow velocity. RESULTS: Among 175 patients, 94.3% suffered from impaired carotid IMT. After acupuncture intervention, 7.7%-10.9% patients had improved IMT but 4.6%-6.3% had aggravated carotid IMT. There was no significant difference of carotid IMT before and after treatment (>0.05). About 50% patients had abnormal intracranial blood flow velocity; after acupuncture intervention, 27.4%-33.3% patients who had the abnormal blood flow velocity had normal one, but 27.0%-52.5% patients who had normal blood flow velocity had abnormal one. After acupuncture intervention, the low-speed blood flow of MCA, VA and BA in female patients aged 41-60 years and the low-speed blood flow of MCA and VA in female patients aged 61-70 years were significantly improved (all <0.05); the high-speed blood flow of MCA and VA in male patients aged 61-70 years and the high-speed blood flow of VA and BA in female patients aged 41-60 years were significantly decreased (all <0.05). CONCLUSION Nearly 95% of patients with mild-to-moderate hypertension had carotid IMT, and about 50% had abnormal blood flow velocity of intracranial artery. The present study failed to found significant effects of acupuncture on carotid IMT, but it shows acupuncture can generally improve the low blood flow velocity in women with mild-to-moderate hypertension.

Background: Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated. Methods: A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation. Results: In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50-67%) for DLBCL patients and 46% (95% CI: 20-69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively. Conclusions: R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.
