Objective:Employing the cascade care model, this qualitative study explores determinants influencing the cascading care stages of hypertension and diabetes by interviewing various stakeholders.Methods:In July 2023, purposive sampling was employed to recruit participants from Gongyi and Wugang cities in Henan Province, and Linqu County in Weifang City, Shandong Province. Semi-structured in-depth interviews were conducted with representatives of policymakers, healthcare institution managers, providers, and patients with hypertension and diabetes.And thematic analysis was performed using both inductive and deductive approaches.Results:A total of 82 individuals were interviewed, with an age range of (53.8±12.0) years, among which 48 (58.5%) were male; including 5 policymakers, 10 institutional managers, 20 healthcare providers, and 47 patients with hypertension and diabetes. The study identified both barriers and facilitating factors at the patient, healthcare provider, and system levels across various stages: awareness, screening, diagnosis, treatment, long-term management, and control of hypertension and diabetes.Conclusion:By delineating and analyzing the barriers and facilitators at each stage of hypertension and diabetes care, this study lays the groundwork for the development of effective, feasible, and sustainable implementation pathways, with significant implications for the enhanced management of hypertension and diabetes in China.

Objective:To employ qualitative research methods to evaluate the sustainability of the Shandong-Ministry of Health Action on Salt and Hypertension (SMASH) interventions and their influencing factors.Method:In September 2023, interviewees meeting the inclusion criteria were recruited through purposive sampling in Jinan, Shandong Province. A semi-structured interview guide was designed based on the CFIR and RE-AIM frameworks. Personal in-depth interviews and focus group discussions were conducted to gather insights on the feasibility, effectiveness, and sustainability of the project interventions from various stakeholders, including representatives from the government, food manufacturers, restaurants, academia, and residents.Results:A total of 15 individuals participated in in-depth interviews, involving six representatives from food manufacturers, four from restaurants, three from the government, and two from academia. There were four focus group discussions with 30 residents. The study found that at the individual resident level, health awareness and the availability of sodium reduction tools in the market could affect their salt reduction practices. For food manufacturers and restaurants, consumers′ preferences, technical challenges in reformulation, and government support were key factors determining the smooth progress of their salt reduction efforts. At the governmental level, multi-sectional coordination, chronic disease management demonstration areas, and the impact of the pandemic were the main factors influencing the implementation of sodium reduction interventions.Conclusion:Future endeavours should strengthen long-term management and optimise the complex influencing factors associated with intervention measures. This will be essential in sustaining and expanding the positive health outcomes achieved through the Shandong population sodium reduction strategy.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To investigate the eye movement characteristics of non-emotional pictures and emotion-al pictures in college students with different self-rating levels of depression.Methods:The Baker Depression Ques-tionnaire(BDI-2)was used to select 20 college students in high score group(BDI-2 score≥ 18 points)and 20 col-lege students in low score group(BDI-2 score ≤2 points).In experiment 1 the different finding tasks were used to investigate the difference of eye movement features between the two groups when viewing non-emotional pic-tures.In experiment 2 the expression recognition tasks were used to investigate the difference of the eye movement features between the two groups when viewing emotional pictures.Results:The results of experiment 1 showed that when completing the judgment task,the fixation times of each interest area of non-emotional images was smaller in the high score group than in the low score group(P＜0.01).The results of experiment 2 showed that the reaction time was longer to sad faces than to happy faces in the high score group(P＜0.05),and the correct rate to sad faces was higher in the high score group than in the low score group(P＜0.05).For the eye interest area,the first fixation arrival time was earlier in the high score group than in the low score group(P＜0.001),and the first fixa-tion time and total fixation time were shorter in the high score group than in the low score group(Ps＜0.01).Con-clusion:College students with high self-rating level of depression show a decrease of interest when viewing non-e-motional pictures,and show an advantage in processing negative emotional information and avoiding eye gaze when viewing emotional pictures.

OBJECTIVE：To investigate the efficacy of hormone combined with cyclophosphamide in the treatment of connective tissue disease-associated interstitial lung disease （CTD-ILD）and to analyze its influential factors. METHODS ：100 patients diagnosed as CTD-ILD in our hospital from Jan. 2018 to Jan. 2019 were randomly divided into observation group and control group ，with 50 cases in each group. Control group was treated with Compound cyclophosphamide tablets ，50 mg each time，3-4 times each day. Observation group was additionally treated with Prednisone acetate tablets ，10 mg each time ，3-4 times each day ，on the basis of control group. Treatment courses of 2 groups lasted for 6 months. The clinical efficacy ，the occurrence of ADR，lung function before and after treatment ，the levels of peripheral IL- 6，CRP and PCT and quality of life （SGRQ score ）were compared between 2 groups. According to the therapeutic efficacy ，all patients were divided into effective group and ineffective group. The related factors influencing the clinical efficacy of CTD-ILD were analyzed by univariate and multivariate Logistic regression analysis. RESULTS ：After treatment ，total response rate ，FVC，FEV1 and DLCO of observation group were significantly higher than those of control group ，while SGRQ score ，levels of IL- 6，CRP and PCT in peripheral blood were significantly lower than control group （P＜0.05）. There was no significant difference in the total incidence of ADR between 2 groups（P＞0.05）. Univariate analysis showed that there were no significant differences in gender ，age，past medical history and CTD type between effective group and ineffective group （P＞0.05）. However ，there were statistical significancant differences in the distribution of different levels of IL- 6，CRP and PCT in peripheral blood between 2 groups（P＜0.05）. Multivariate Logistic regression analysis showed that IL- 6 was an independent risk factor for therapeutic efficacy of combined therapy [OR （95％CI）＝ 4.537（3.668，10.352），P＝0.002]. CONCLUSIONS ：Hormone combined with cyclophosphamide can significantly improve the therapeutic efficacy of CTD-ILD patients ，improve their lung function and quality of life ，and reduce the expression level of inflammatory factors. The level of IL- 6 is an independent risk factor affecting the efficacy of the treatment ，and its changes should be paid close attention to during the treatment.

Objective:The clinical characteristics of patients with primary central nervous system lymphoma-diffuse large B-cell lymphoma (PCNSL-DLBCL) and the effects of different treatment schemes on their survival and prognosis were analyzed retrospectively.Methods:A total of 49 patients with PCNSL-DLBCL who presented at the Tianjin Medical University General Hospital from July 2014 to December 2020 were included, and their clinical data were retrospectively analyzed. They were divided into four groups: the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group. The median overall survival (OS) and progression-free survival (PFS) were calculated, and the survival prognosis was compared by univariate and multivariate prognostic analysis.Results:The median OS time of the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group was 16.5 months, 4.5 months, 42 months, and not reached, respectively ( P<0.001) . The median PFS time of the MTX group, the R-CDOP group, the BTKi-R-MTX group, and the RLZT group was 7 months, 1.5 months, 20 months, and 5 months, respectively ( P=0.005) . Multivariate prognostic analysis showed that double expressor lymphoma, IESLG risk grade, and different treatment methods were the prognostic factors of PCNSL-DLBCL. Conclusion:The survival and prognosis of PCNSL-DLBCL are affected by different treatment schemes. The role of CD20 monoclonal antibody in the treatment of PCNSL-DLBCL is still controversial. The treatment scheme containing BTKi has great potential for PCNSL-DLBCL. RLZT scheme has a good prospect for elderly patients who cannot tolerate high-dose chemotherapy and radiotherapy.

Objective:To evaluate the value of a novel multiphase three-dimensional deep learning neural network of computer-aided diagnosis (CAD) used in LDCT lung cancer screening.Methods:Eight thousand eight hundred and fifty volunteers with 1 111 nodules were enrolled in the lung cancer screening from November of 2013 to December of 2017, and the baseline LDCT imaging data of volunteers accompanied with clinical information were retrospectively analyzed. All volunteers in this study were designed to receive LDCT test at least once. All the imaging of volunteers were read through the methods of visual detectioin (VD), CAD, and VD Combined CAD. The criteria of the true pulmonary nodule was determinated by the consistent opinion of two specialists in chest imaging（in case of disagreement, the decision should made by the third chief physician). In terms of the numbers, types or Lung-RADS categories of nodules, the detection rate, missed diagnosis rate and false positive rate of pulmonary nodules or lung cancer among three methods were compared, and the rates between groups were compared by χ 2test. Results:Compared with VD or CAD ,the detection rate of nodules in the CAD combined VD was significantly increased (95.7% , 94.2%, vs. 80.1% P<0.05 ), and the rate of missed diagnosis was significantly reduced (5.8%, 4.3% vs. 19.9% ，χ2=101.650, 128.500 ，P<0.05); Compared with VD, the methods of CAD or VD combined CAD significantly increased the the detection rates of Lung-RADS categories (χ2 =25.083,23.449, P=0.000, 0.000) or different types of nodules (χ2=6.955,6.821, P=0.031, 0.033), but there was no statistically significant difference between CAD and VD combined CAD for Lung-RADS categories and different types of nodules (all P>0.05); Compared with VD and VD combined CAD, the positive prediction rate of CAD for lung cancer was significantly reduced, and the rate of missed diagnosis and false positive rate were significantly increased, but there was no significant difference between VD and VD combined CAD in the prediction rate, missed diagnosis rate and false positive rate of lung cancer. Conclusion:The method of CAD combined VD can reduce the detection of false positive nodules and improve the detection rate of true pulmonary nodules,which is the preferred method using in LDCT lung cancer screening for city population.

Objective:To observe the effect of autophagy of condylar chondrocytes on apoptosis in temporomandibular joint osteoarthritis (TMJOA) of rats.Methods:Fourty male 2-month-old SPF SD rats were equally divided into sham group ( n=20) and experimental group ( n=20). UAC metal prosthesis was cemented to the left incisors of maxilla and mandible of the rats in experimental group rats. After 8 weeks, all rats were sacrificed and the temporomandibular joint was taken. Two groups of rat condylar chondrocytes were extracted and cultured in vitro to the third generation. Immunofluorescence technique was used to detect the levels of collagen Ⅱ and matrix metalloproteinase-13 (MMP-13) in chondrocytes. The level of light chain-3 (LC-3), an autophagy marker of chondrocytes, was detected. Immunohistochemical technique was used to detect the level glycogenin-1, a glycogen formation marker of chondrocyte, was detected. The level of caspase-3, an apoptosis marker of chondrocyte, was also detected. Tunel technique was used to detect the apoptosis rate of the two groups at 72 h.
