The literature in CNKI and Web of Science databases using bibliometric methods, and reviewed the research progress of bromine extraction by gaseous membrane method in aspects such as the number of publications, major publishing countries/institutions and research hotspots. The results show that the number of articles on bromine extraction by gaseous membrane method has been increasing in phases; early research, high attention and largest number of publications in the United States; Chinese Academy of Sciences, Institute of Tianjin Seawater Desalination and Multipurpose Utilization of State Oceanic and Administration and Tiangong University have a high influence among the domestic research institutions; early research focus of bromine extraction by gaseous membrane method are mass transfer principles, mass transfer dynamics, membrane components, membrane materials and factors affecting mass transfer, and gradually extend to the improvement of membrane materials, new cells, bromine derivatives, flame retardants and their environmental impact.

Objective To investigate the awareness of knowledge of diabetic kidney disease (DKD) and related factors in six provinces in China. Methods From December 2021 to March 2022, a cross‑sectional survey study using a structured questionnaire was conducted among 6 230 type 2 diabetes (T2DM) patients aged 18 years and above in six provinces in China (Heilongjiang Province, Hubei Province, Guangdong Province, Gansu Province, Tianjin City, and Chongqing City). The survey collected information on the patients′ general characteristics (gender, education level, region, residential area, and duration of diabetes), awareness of DKD prevention and treatment knowledge (including common symptoms of kidney disease, DKD risk factors, and DKD prevention and control measures), and self‑assessment of DKD knowledge and skills. The Chi‑square test was used for inter‑group comparisons. Results Only 18.15% (1 131/6 230) of patients were aware of anemia and fatigue as common symptoms of kidney disease, while 36.84% (2 295/6 230) had no knowledge of any common symptoms of kidney disease. In terms of awareness of DKD risk factors, only 17.61% (1 097/6 230), 16.95% (1 056/6 230), and 13.34% (831/6 230) of the respondents were aware of acute kidney injury, nephrotoxic substances, and excessive protein intake, respectively, while 32.81% (2 044/6 230) had no knowledge of any DKD risk factors. Regarding knowledge of DKD prevention and control measures, only 44.96% (2 801/6 230), 37.37% (2 328/6 230), 33.87% (2 110/6 230), and 25.81% (1 608/6 230) of patients were aware of medication adherence, regular follow‑up and monitoring, blood pressure control, and lipid control, respectively, while 20.13% (1 254/6 230) had no knowledge of any DKD prevention and control measures. Comparison of the knowledge of DKD prevention and treatment among different groups showed that male patients, those from the northern regions, those with a higher level of education, and those with diabetes mellitus for 10 years or more had higher awareness rates of common symptoms, risk factors, and prevention and control measures for DKD (P<0.05). Compared with rural residents, urban residents had higher awareness rates of common symptoms and risk factors of kidney disease (P<0.01). Conclusions The awareness levels of common symptoms of kidney disease, DKD risk factors, and prevention and control measures among diabetes patients in six provinces in China are relatively low, and there are significant differences in awareness levels among diabetes patients of different genders, residential areas, regions, education levels, and disease courses.

Objective To investigate the association between neutrophil to lymphocyte ratio (NLR) and renal tubular injury in type 2 diabetes mellitus patients (T2DM). Methods A total of 258 patients with T2DM were selected in this study. Data of the general data, the absolute values of neutrophils and lymphocytes were collected. The NLR was calculated. The 24 h urinary microalbumin (24 h UMA) and renal tubular markers β2-microglobulin (β2-MG), β -galactosidase (GAL), and retinol-binding protein (RBP), N-acetyl- β -D-glucosidase (NAG) were detected by immunity transmission turbidity. The renal tubular function was considered as the normal if the above four markers were normal. If any one or more markers exceed the upper limit, it was regarded as renal tubular injury. The patients were divided into the normal group (n=142) and the injury group (n=116) according to whether the renal tubular function was impaired. The difference of NLR levels was compared between the two groups. According to the presence of any one, two and three types of renal tubular marker abnormalities, the patients in the injury group were divided into subgroups, and the differences of NLR levels were compared between the subgroups. In addition, the correlation between NLR and β2-MG, GAL, RBP and NAG was analyzed. Binary Logistic regression was used to analyze the influencing factors of renal tubular injury in patients with T2DM. Results The level of NLR was significantly higher in the injury group than that of the normal group (P＜0.05). The level of NLR increased gradually with the increase of abnormal types of renal tubular markers and the aggravation of the renal tubular damage (P＜ 0.05). NLR was positively correlated with β2-MG, GAL, RBP and 24 h UMA (r =0.191, 0.152, 0.131 and 0.158, P＜0.05). Logistic regression analysis showed that the higher levels of NLR and 24 h UMA were risk factors for renal tubular injury in patients with T2DM, and the higher level of HDL-C was its protective factor. Conclusion NLR is closely related to renal tubular injury in patients with T2DM, and which can reflect the degree of renal tubular damage. [ABSTRACT FROM AUTHOR]

Natural saline water is a valuable source of inorganic salts・ Currently, the main types of saline water include seawater, salt lakes, and underground brine・ Natural saline water also contains significant reserves of high・value trace elements such as rubidium cesium, uranium, bromine, iodine, and strontium・ The development and utilization of these trace elements are crucial for the comprehensive and sustainable utilization of natural saline water resources・ This paper analyzes and summarizes recent advancements in the separation and extraction of rubidium cesium, uranium, bromine, iodine, and strontium from natural saline water along with related technologies・ It provides an overview of application approaches, status quo in separation and extraction methods, and highlights the challenges faced by these trace elements, to offer insights into their efficient recovery from natural saline water resources.
