OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

During cardiopulmonary resuscitation (CPR), the depth of compression is a critical factor affecting the effectiveness of the rescue and the patient's prognosis. However, it is difficult to master the correct compression depth in manual CPR. If the compression depth is too deep, it may cause rib fractures, while insufficient compression depth may fail to establish effective circulation. Although most existing manual CPR compression depth control devices can indicate the depth but lack direct limiting functions. Against this background, led by a team of faculty and students from the Department of Emergency and Rescue Medicine at Xuzhou Medical University, on the basis of the development of a portable CPR protection device (National Invention Patent of China, patent number: ZL 2021 1 0309001.4), the device's compression depth limiting performance was further expanded, and then a new type of CPR compression depth limiting device suitable for different body types was developed. This device has applied for a National Invention Patent of China (patent application number: ZL 2023 1 0644910.2) and has been granted a National Utility Model Patent of China (patent number: ZL 2023 2 1384853.0). The device consists of a horizontal support beam, a vertical sliding beam, a guide block, a rotating shaft, a rotating arm, a limit slider and a limit pin. The horizontal support beams of the two limit devices are fixed horizontally to the horizontal side beams of the portable CPR protection device by bolts, and the connecting arms at the bottom of the vertical sliding beams are fixedly connected with the pressing mechanism, so that precise control of the pressing depth in CPR operation can be realized according to the patient's body size by the mechanical linkage of the vertical sliding beams and the rotating arms, as well as by the blocking and limiting effect of the rotating arms and the guiding blocks on the limiting sliders. It can prevent the occurrence of complications such as chest wall fractures, and thereby increase the success rate of manual CPR, and its structure is simple, low-cost, and suitable for social popularization.

OBJECTIVE: This study explored the job choice preferences of Center for Disease Prevention and Control (CDC) workers to provide CDC management information and recommendations for optimizing employee retention and motivation policies. METHODS: A discrete choice experiment was conducted in nine provinces across China. Seven key attributes were identified to analyze the job preferences of CDC workers. Mixed logit models, latent class models, and policy simulation tools were used. RESULTS: A valid sample of 5,944 cases was included in the analysis. All seven attributes significantly influenced the job choices of CDC workers. Heterogeneity analyses identified two main groups based on different levels of preference for attribute utility. Income-prioritizers were concerned with income and opportunities for career development, whereas bianzhi-prioritizers were concerned with bianzhi and welfare benefits. The policy simulation analysis revealed that income-prioritizers had a relatively higher sensitivity to multiple job preference incentives. CONCLUSION Income and bianzhi were the two key attributes influencing the job choices and retention preferences of CDC workers. Heterogeneity in job preferences was also identified. Based on the preference characteristics of different subgroups, policy content should be skewed to differentiate the importance of incentives.

Objective To analyze the effects of three sterilization methods,namely,pressure steam,low-temperature plasma and ethylene oxide,on the magnetic flux of magnetic surgical devices and their sterilization costs.Methods A total of 234 magnetic surgical devices of different specifications and models(magnetic rings)were randomly divided into Group A,Group B and Group C after the paired number was labelled,and each group consisted of 78 pieces(39 pairs).After packaging each pair of devices according to sterilization specifications,Group A was sterilized by pressure steam,Group B was sterilized by low-temperature plasma,and Group C was sterilized by ethylene oxide.We measured the magnetic flux of three sets of magnetic rings before and after sterilization,and comparatively analyzed the sterilization cost and sterilization time of the single package.Results There was no statistically significant difference in the impact of the three sterilization methods on the magnetic flux of the magnetic surgical devices(P＞0.05),but there was a significant difference in the magnetic flux before and after sterilization for each sterilization method(P＜0.001);the sterilization cost was(1.96±0.16)yuan for Group A,(23.17±0.32)yuan for Group B,and(8.16±0.18)yuan for Group C,showing statistically significant differences among the three groups(P＜0.01).The sterilization time was(65.21±3.36)min for Group A,(45.46±1.39)min for Group B,and(1020.38±12.21)min for Group C,with statistically significant differences among the three groups(P＜0.01).Conclusion None of the three sterilization methods affects the magnetic flux of the magnetic surgical devices.Pressure steam method shows the lowest cost of single package,low-temperature plasma method shows the highest cost of single package,while ethylene oxide method shows the highest sterilization time.Pressure steam should be the preferred sterilization method for magnetic surgical devices.

Objective Recombinase-aided polymerase chain reaction(RAP)is a sensitive,single-tube,two-stage nucleic acid amplification method.This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA),and Acinetobacter baumannii(AB)in the bloodstream based on recombinant human mannan-binding lectin protein(M1 protein)-conjugated magnetic bead(M1 bead)enrichment of pathogens combined with RAP. Methods Recombinant plasmids were used to evaluate the assay sensitivity.Common blood influenza bacteria were used for the specific detection.Simulated and clinical plasma samples were enriched with M1 beads and then subjected to multiple recombinase-aided PCR(M-RAP)and quantitative PCR(qPCR)assays.Kappa analysis was used to evaluate the consistency between the two assays. Results The M-RAP method had sensitivity rates of 1,10,and 1 copies/μL for the detection of SA,PA,and AB plasmids,respectively,without cross-reaction to other bacterial species.The M-RAP assay obtained results for<10 CFU/mL pathogens in the blood within 4 h,with higher sensitivity than qPCR.M-RAP and qPCR for SA,PA,and AB yielded Kappa values of 0.839,0.815,and 0.856,respectively(P<0.05). Conclusion An M-RAP assay for SA,PA,and AB in blood samples utilizing M1 bead enrichment has been developed and can be potentially used for the early detection of bacteremia.

Objective: To analyze the current situation and related factors of physical exercise behavior among high school students, so as to provide theoretical basis for improving their health level. Methods: In May 2022, a stratified cluster random sampling method was used to select 17 high schools in the jurisdiction of Taizhou City. A total of 3 402 high school students were selected by class to conduct a survey on the prevalence and related factors of physical exercise behavior by Chinese Sports Activity Level Scale. And binary Logistic regression analysis was conducted to analyze the influencing factors. Results: Among the surveyed high school students, the rate of poor physical exercise behavior reached 53.4%. The rates of poor physical exercise behavior varied within the group in terms of gender, urban and rural areas, whether they were only children, maternal education, parental emotions, parental exercise habits, parenting styles, family income and academic performance were statistically significant (χ2=12.38, 11.73, 742.71, 28.86, 24.38, 39.98, 71.92, 33.34, 176.97, P<0.01). High school students of grade 3, female students, parents with low education, parents who occasionally and never exercise, intergenerational discipline, low family income, and average academic performance were the tendency factors for poor physical exercise behavior(OR=1.39, 1.18, 1.62, 1.30, 1.36, 2.21, 1.53, 1.46, 1.52, P<0.05). Conclusions The rate of poor physical exercise behavior among high school students in Taizhou City is relatively high and is affected by various factors such as age, gender, academic performance, and family background. It should actively reduce the impact of unfavorable factors, promote high school students to participate in physical exercise, and improve the health level of high school students.
