Abstract: Objective　To evaluate the free thalassaemia screening programme for preconception and pregnancy in Hainan Province, and to provide a theoretical basis for optimizing the screening process for thalassaemia. Methods From November 2020 to July 2021, a survey was conducted on 10 396 adults with Hainan household registration who participated in the Epidemiological Survey of Thalassemia in Hainan Residents in 19 cities and counties of Hainan Province. All of them underwent routine blood tests, haemoglobin electrophoresis tests and genetic tests for thalassaemia. The optimal diagnostic cut-off values for mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and haemoglobin adult type 2 (HbA2) were determined using screening test indexes such as receiver operating characteristic curve and sensitivity. The diagnostic effectiveness of different primary screening programs for thalassemia gene carriers was evaluated. Results Using the existing MCV single-indicator thalassemia primary screening protocol in Hainan Province, where individuals with MCV<82 fL undergo thalassemia gene testing, resulted in a high missed diagnosis rate (34.06%) and low sensitivity (65.94%). The optimal cut-off values for MCV screening for alpha-and beta-thalassaemia were 84.45 fL and 79.05 fL, respectively; the optimal cut-off values for MCH screening for alpha-and beta-thalassaemia were 27.95 pg and 25.15 pg, respectively. The optimal cut-off value for HbA2 screening for alpha-thalassaemia was less than 2.55% and greater than 3.35% for beta-thalassaemia. The "combined HbA2 or MCH or MCV screening protocol" with the cut-off values recommended in this study had a better performance in primary screening for thalassemia, with the highest sensitivity (92.96%) and negative predictive value (92.67%) and the lowest underdiagnosis rate (7.04%), statistically significant differences compared with the existing protocol (P<0.05). Conclusions The current process of screening for thalassemia in Hainan Province may lead to missed diagnoses. The combined use of MCV, MCH and HbA2 for thalassemia screening, adopting locally suitable cutoff values for primary screening indicators, can improve the incidence of missed reporting of thalassemia and enhance diagnostic effectiveness.

For patients with newly diagnosed glioblastoma, tumor treating fields (TTF) combined with temozolomide after radiation therapy is currently one of the standard therapeutic regimens. Recently, TTF has been increasingly applied in combination with radiation therapy since it can delay tumor DNA repair and increase DNA replication stress. The efficacy of TTF has been proven in clinical studies. However, no consensus has been reached regarding the theoretical basis, radiation dose, actual clinical operation, patients' benefit and safety, which remain controversial. In this article, research progress on these topics was reviewed.

Objective To investigate the effect of resistance training on the rehabilitation of patients after hip replacement with the framework of the theory of planned behavior(TPB).Methods A total of 85 patients of hip fracture patients in Gansu Provincial Hospital of Traditional Chinese Medicine from July 2022 to April 2023 were selected as research objects.The patients were separated into intervention group(n=43)and control group(n=42)by random sampling.Both groups were treated with routine nursing,and the intervention group was given resistance training based on TPB.The intervention time was 3 months.The Harris hip score(HHS),36-item short form(SF-36)score and Barthel index(BI)scores of the two groups were compared before intervention,1 month and 3 months after intervention,as well as the functional exercise compliance score of the patients 3 months after intervention.Results After 1 month and 3 months of intervention,the HHS,SF-36 score and BI score of intervention group were better than those of control group,and after 3 months of intervention,the executive ability of functional exercise in intervention group was significantly higher than that of control group,and the mean difference was significant(P＜0.05).Conclusion Resistance training led by TPB can effectively improve the functional exercise compliance of patients after total hip arthroplasty,improve the muscle strength,balance ability and joint stability of patients,and then improve the daily activity ability and quality of life.

OBJECTIVETo observe the effect of Euphorbia kansui (E. KS) alcohol extracts on urination and kidney-related expressions of mice injected with normal saline and to discuss its impact on kidney.

METHODMice intraperitoneally injected with normal saline were observed for urination and changes in kidney-related histiocytic factors of after intragastrical administration of E. KS and compared with normal mice.

RESULTE. KS alcohol extracts can promote urination of mice injected with normal saline and enhance peripheral serum creatinine, with no obvious pathological change showed in tissue sections. It had a certain effect on reducing AQP2 expression and enhancing TNF-alpha expression.

CONCLUSIONEuphorbia kansui in large dose has a remarkable effect on kidney but may be accompanied with pathological reactions to some extent, especially the dose of 1.2 g x kg(-1). The pathological reactions may be related with increased serum creatinine and TNF-alpha expression.

Objective:To describe the current situation on quit intention and quit attempts among current smokers aged 15 years and above in China and explore the main factors affecting their smoking cessation behaviors.Methods:The subjects were people aged 15 years and above in China. A stratified multi-phased randomized cluster sampling method was used. The survey covered 200 districts/counties in 31 provinces (autonomous regions and municipalities directly under the central government), including 19 376 people under investigation. The data were weighted with SAS 9.4 for complex sampling analysis, and the frequency and weighted component ratio were used for description. The influencing factors were studied using the Rao Scott χ2 test and unconditional multivariate logistic regression. Results:Among current smokers, 6.63% reported that they planned to quit smoking in the next month, 5.44% for men and 8.49% for women. 17.96% of the current smokers made quit attempts in the past 12 months, with 17.80% men and 22.15% women. People who smoke occasionally ( OR=3.42, 95% CI: 2.09-5.59) made quit attempts in the past ( OR=4.91, 95% CI: 0.33-0.52) and knew that smoking would lead to three diseases ( OR=2.24, 95% CI: 1.48-3.40) had higher quit intention. People who occasionally smoke ( OR=1.68, 95% CI: 1.20-2.34) received smoking cessation suggestions from medical staff ( OR=1.96, 95% CI: 1.62-2.37), were a ware of that smoking causes three diseases ( OR=1.63, 95% CI: 1.32-2.02) and had smoking prohibition regulations in indoor areas of their homes, had a higher rate of quit attempts. Conclusion:Providing effective smoking cessation intervention services and creating a supportive tobacco control environment are significant in promoting smoking cessation behavior.

Objective:To investigate the exposure to tobacco advertisements and promotions among Chinese adults aged 15 and above, identify the publicity channels and forms of tobacco advertising and promotion in 2010 and 2018, and implicate further tobacco control measures in China.Methods:A multistage, stratified, randomized cluster sampling design was used in 2010 and 2018 China Adult Tobacco Survey, with national representativeness. 13 354 and 19 376 permanent residents were selected in the 2010 and 2018 surveys. SAS 9.4 software was applied for data analysis, and all the data were weighted based on a complex sampling design. Rao Scott χ2 test was used for group comparison of a single factor. Results:In 2010 and 2018, 19.61% and 18.14% of the survey respondents did see tobacco advertising and promotion. From 2010 to 2018, there was no significant change in the situation of tobacco advertisements and promotions. Among those who had gone to a cigarette shop, the proportion of seeing tobacco advertisements increased from 29.28% in 2010 to 43.28% in 2018. Among those who had seen tobacco advertisements on TV, the rate fell from 50.93% in 2010 to 28.58% in 2018. Among those who had gone to movie theaters, the proportion of seeing tobacco advertisements increased from 2.17% in 2010 to 9.89% in 2018. Among those who had used the Internet, the proportion of seeing tobacco advertisements online rose from 19.20% in 2010 to 42.30% in 2018. In terms of tobacco promotion, the percentages of people who had seen tobacco promotions, cigarette price discounts, cigarette discount coupons, gifts, and other preferential activities in various places in the past 30 days were 4.99% vs. 9.30%, 0.78% vs. 4.09%, 0.04% vs. 0.33% and 0.98% vs. 3.33% in 2010 and 2018, respectively ( P<0.001). Conclusions:Tobacco advertising and promotion are still prevalent in China, with no significant change in 2010 and 2018. Tobacco advertising and promotion have been with the constant changes and development of media platforms. It is necessary to improve the implementation of relevant policies, comprehensively ban tobacco advertisements and promotions, and strengthen the supervision of ads and promotions.
