Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

Objective:To assess the impact of the construction of smoke-free government on the smoking and cessation behaviors of staff members.Methods:This was a retrospective cohort study. The study used stratified random cluster sampling method to select 144 government institutions from 31 Provinces (Autonomous Regions and Municipalities) and the Xinjiang Production and Construction Corps. The survey was carried out between October and November, 2023 by filling out questionnaires online among the insiders of the institutions and all the smoking staff members. The main indicators included the number of smokers before and after the construction of smoke-free governments and the measures for the construction of smoke-free governments. 144 questionnaires from insiders were recovered, all of which were included in the analysis; 1 776 questionnaires from smokers were recovered, including 1 716 valid questionnaires. The SAS 9.4 was used to perform χ 2 test and log-binomial regression analysis. Results:The percentage of smoking staff members decreased from 8.81% before the construction to 6.70% after the construction, and the difference was statistically significant ( χ 2=63.23, P<0.001). Comprehensive smoking ban in indoor public places ( OR=2.301, 95% CI: 1.433-3.694), punishment mechanism for smoking staff members ( OR=1.219, 95% CI: 1.124-1.322), smoking cessation competitions ( OR=1.865, 95% CI: 1.234-2.818) and reimbursement for or provision of smoking cessation medications ( OR=2.210, 95% CI: 1.002-4.874) were facilitators to motivate the smoking staff members to quit (all P<0.01). Numbers of smoking leaders ( OR=0.858, 95% CI: 0.807-0.913) and smoking years of smoking staff members ( OR=0.932, 95% CI: 0.918-0.946) negatively influenced the smoking staff members to quit (both P<0.001). Conclusions:The construction of smoke-free governments can effectively promote the smoking cessation behaviors of smoking staff members. In addition, comprehensive smoke-free policies, punishment mechanism for smoking staff members and activities such as smoking cessation competitions, and reimbursement for or provision of smoking cessation medications are important.

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.

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.

【Objective】 To investigate the correlation between early immune reconstitution and clinical outcomes in patients with acute lymphoblastic leukemia (ALL) underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). 【Methods】 The basic information and treatment data of 99 patients with ALL undering allo-HSCT from December 2018 to February 2022 were collected. The proportions of CD3⁺ T, CD3⁺CD4⁺ T, CD3⁺CD8⁺ T and CD3^-CD16⁺CD56⁺ NK cells were detected before and 30, 60 and 90 days after transplantation using flow cytometry. The correlation between early cellular immune reconstitution and neutrophil engraftment, platelet engraftment, infection, and acute and chronic graft-versus-host disease (GVHD) was analyzed. 【Results】 Among 99 ALL patients, the median time of neutrophil engraftment was day +11 (range, 8-28), and the median time of platelet engraftment was day +14 (range, 10-120). The cumulative incidence of blood stream infection (BSI) was 11.10% and the cumulative incidence of CMV within 100 days of transplantation was 40.40%. The cumulative incidence of EBV within 100 days was 7.10%. The cumulative incidence of acute graft-versus-host disease (aGVHD) was 22.30%. The cumulative incidence of chronic graft-versus-host disease (cGVHD) within 1 year of transplantation was 16.20%. 1 -year cumulative relapse rate was 13.84%. The 1 -year cumulative disease-free survival (DFS) for all patients was 80.60% and the 1-year overall survival (OS) was 90.30%. The CD4⁺/CD8⁺ ratio was positively associated with the development of aGVHD at 30 days post-transplant (OR 1.21, 95CI 1.01-1.45, P<0.05). The proportion of CD16⁺ CD56⁺ NK cell were higher in the group without BSI than that in the BSI group before and 30 days after transplantation (P < 0.05). The proportion of CD4⁺ T-cell were lower in the CMV infection group than that in the group without CMV infection at 60 and 90 days post-transplant(P<0.05). The higher level of CD4⁺ T-cells at 60 days post-transplant was a protective factor for CMV infection within 100 days (HR 0.91, 95CI 0.84-0.99, P<0.05). 【Conclusion】 Early immune reconstitution after allo-HSCT in patients with ALL is associated with aGVHD, CMV and BSI.

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 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 secondhand smoke (SHS) exposure among non-current smokers aged 15 and over and its influencing factors in China in 2010 and 2018.Methods:The 2010 and 2018 China Adult Tobacco Surveys used multistage stratified cluster random sampling methods to obtain national representative samples across 31 provinces (autonomous regions and municipalities) in China. This study selected non-current smokers aged 15 and over as the research subjects to describe the general demographic characteristics, perceptions of SHS hazards, attitudes towards smoking bans in indoor areas in public places, and SHS exposure and the smoking restriction regulations in different places. The Rao-Scott χ2 test was used to compare the rates, and the unconditional logistic regression was used to analyze the influencing factors of SHS exposure. All the subjects in the analysis were weighted based on a complex sampling design. Results:Among non-current smokers aged 15 and over, from 2010 to 2018, the percentage of indoor smokers had decreased from 84.7% to 71.9%. The rates of people who saw smoking in various places declined with a statistically significant difference ( P<0.001). The exposure to SHS for females, people aged 45-64, teachers, medical staff, workers in enterprises, businesses, waiters, and people who live in rural and central areas declined. The differences were statistically significant ( P<0.05). In 2018, the percentage of SHS exposure for those who reported a comprehensive smoking ban in households or allowed smoking in certain areas was lower than for those who reported allowed or without a smoking ban. Among those aged 25-44, SHS exposure for those who reported complete smoking prohibition in workplaces was lower than those who reported allowed or without smoking prohibition ( OR=0.65, 95% CI: 0.49-0.87). The proportion of SHS exposure for those who believe that smoking should not be allowed in indoor areas of 0-5 public places is higher than that smoking should not be allowed in the indoor spaces of 8 public places ( OR=2.13, 95% CI: 1.35-3.36). Among people aged 45-64, the proportions of SHS exposure for teachers ( OR=0.37, 95% CI: 0.17-0.78) and medical staff ( OR=0.35, 95% CI: 0.16-0.76) and staff working in agriculture, forestry, animal husbandry, fishery, and water conservancy were lower than governmental staff ( OR=0.49, 95% CI: 0.29-0.84). Conclusions:Data from the decreased exposure of Chinese non-current smokers aged 15 and over to SHS suggests the initial achievement through constructing a smoke-free environment, but continued efforts are needed. It is necessary to actively advocate for smoke-free families, strengthen publicity and education on the hazards of tobacco and SHS, and improve the skills of non-smokers in rejecting SHS exposure.

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.

Objective : To study the distribution range of the color values of the upper anterior teeth of Uygur youth in the Kashi area of XinJiang as a reference for clinical applications. Methods: Based on the International Commission on Illumination (CIE) L*a*b* color system, the colorimetric values of the anterior teeth of 212 Uygur youths in Xinjiang, Kashi, were analyzed by digital camera colorimetry. There were 105 males and 107 females. The length of the neck to the cutting end of the tooth was measured, and the tooth was evenly divided into thirds. To determine the chromaticity values of the incisors, lateral incisors, cuspids, and middle teeth, 1/3 of the cervical, middle and incisal regions and 9 test areas were measured. Results : The color of the cervical, middle and incisal regions of the same tooth position in Uygur youth in the Kashi area showed the following trends: L* value: middle regions > cervical regions > incisal regions; a* value: cervical regions > incisal regions > middle regions; b* value: cervical regions > middle regions > incisal regions, and the differences were statistically significant (P < 0.05). The value of L* gradually decreased, and the value of a* gradually increased (P < 0.05). There were no significant differences in the a* value of male and female maxillary anterior teeth (P > 0.05). However, there was a significant difference in the b* value between the middle teeth and the incisors, the middle and the incisal regions of the upper maxillary incisors, and the cutting end of the upper maxillary incisors (P < 0.05). Conclusions There was a significant difference in the color of the cervical, middle and incisal of the same tooth. The upper jaw gradually reduced from the incisors to the sharp teeth, and the color gradually became reddish. The maxillary central incisor was brighter in males than in females, and the middle and incisal regions of the maxillary front teeth were more yellow than in males than in females.
