Objective: To analyze the compliance status of physical fitness indicator and lifestyle characteristics among secondary vocational school students, as well as their associations, so as to provide a reference for physical fitness promotion among secondary vocational school students. Methods: Using a convenience sampling method, a questionnaire survey and physical fitness tests were conducted from September to December 2024 among 5 141 secondary vocational school students recruited from 16 secondary vocational schools across 8 provinces/municipalities in China, including Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai and Zhejiang. Data on lifestyle factors were collected using a self designed questionnaire combined with standardized scales, including dietary habits, unhealthy behaviors, and 24 hour behaviors (physical activity, screen time, and sleep behavior). Multivariable Logistic regression model was used to analyze the associations of individual lifestyle behaviors and clustering of unhealthy lifestyle behaviors with non-compliance in physical fitness indicators among secondary vocational school students. Results: The compliance rates for waist circumference, vital capacity, grip strength, standing long jump, 30 second sit ups, 20 meter shuttle run, 50 meter dash, sit and reach, 20 second side steps among secondary vocational school students were 55.9%, 89.6%, 81.8%, 79.4%, 77.8%, 61.4%, 87.0%, 12.6%, and 63.5%, respectively, with a non-overweight/obesity rate of 78.9%. The reporting rates of daily breakfast consumption, milk consumption, and vegetable consumption were 58.9%, 18.3%, and 37.5%, respectively. The reporting rates of frequent takeout consumption, frequent sugar sweetened beverage consumption, smoking, alcohol drinking, insufficient moderate to vigorous physical activity (MVPA), excessive screen time, and insufficient sleep were 30.0%, 43.8%, 8.4%, 15.8%, 42.9%, 90.8%, and 42.6%, respectively. Multivariable Logistic regression analysis showed that secondary vocational school students with insufficient MVPA had higher risks of non-compliance in vital capacity, grip strength, standing long jump, 30 second sit ups, 20 meter shuttle run, 50 meter dash, and 20 second side steps ( OR =1.22- 1.60 ); secondary vocational school students who consumed breakfast daily had lower risks of non-compliance in vital capacity and overweight/obesity ( OR =0.81, 0.85); daily vegetable consumption was associated with a lower risk of vital capacity non-compliance ( OR =0.72); frequent takeout consumption was associated with an increased risk of non-compliance in the sit and reach test ( OR =1.28); smoking was associated with increased risks of non-compliance in the 20 meter shuttle run and 20 second side steps ( OR =1.38, 1.58) (all P <0.05). Regarding the clustering of unhealthy behaviors, secondary vocational school students with 4- 5 clustered unhealthy behaviors had higher risks of non-compliance in waist circumference and standing long jump; those with≥6 clustered behaviors had higher risks of non-compliance in standing long jump, 20 meter shuttle run, and 20 second side step ( OR = 1.17-1.36, all P <0.05). Conclusions The clustering of unhealthy behaviors is negatively associated with physical fitness status among secondary vocational school students. Secondary vocational schools should prioritize the promotion of comprehensive lifestyle management to improve the physical fitness levels of secondary vocational school students.

Radiation-induced injury, a body dysfunction caused by irradiation, is associated with the dose, duration, and speed of radiation and is predominantly derived from radiation therapy for patients with malignant tumors. The current clinical treatment mainly includes amelioration of injury, alleviation of symptoms, and improvements in function restoration of the affected sites because of lack of targeted agents specific to radiation-induced injuries. Research and development of preventive and therapeutic agents against radiation-induced injuries are of great significance to reduce the body damages caused by radiotherapy and improve the quality of life of cancer survivors. This review summarizes the radiation-induced injury and its mechanisms, radioprotectants, and therapeutic agents for radiation, and proposes future development directions, so as to provide a reference for alleviation of radiation-induced injury and improvement in prognosis.

Solid organ transplantation has significantly prolonged the survival of patients with end-stage diseases. However, long-term use of immunosuppressants will increase the risk of post-transplantation diabetes mellitus (PTDM) in the recipients, thereby elevating the risk of infection, cardiovascular disease and death. In recent years, with persistent improvement of diagnostic criteria of PTDM, clinicians have deepened the understanding of this disease. Compared with type 2 diabetes mellitus, PTDM significantly differs in pathophysiological characteristics and clinical progression. Hence, different treatment strategies should be adopted. Early identification of risk factors of organ transplant recipients, early diagnosis and intervention are of significance for improving the quality of life of recipients, prolonging the survival of grafts and reducing the fatality of recipients. Therefore, the diagnosis, incidence and risk factors of PTDM were reviewed in this article, aiming to provide reference for clinicians to deliver prompt diagnosis and intervention for PTDM.

Multiple primary malignancies (MPMs) are two or more primary malignancies diagnosed in the same patient at the same time or at a specific time and do not represent progression, recurrence or metastasis of the first tumor.MPMs are extremely rare. In this paper, we reported a case of male patient who was diagnosed with invasive uroepithelial carcinoma, rectal adenocarcinoma, clear cell renal cell carcinoma and sarcomatoid carcinoma of the bladder, and open partial cystectomy, laparoscopic radical operation for rectal cancer, laparoscopic partial left nephrectomy, transurethral resection of bladder tumor and laparoscopic radical cystectomy with ureterostomy were performed, respectively.The patient was followed up for 16 months after the last surgery, with good general condition and no recurrence or metastasis.

Objective:To compare the clinical efficacy and safety of intra-articular platelet rich plasma combined with hyaluronic acid and platelet rich plasma alone in the treatment of knee osteoarthritis.Methods:The relevant literatures published between January 2010 and December 2021 on the randomized control study of intra-articular injection of platelet rich plasma and hyaluronic acid and injection of platelet rich plasma only in the treatment of knee osteoarthritis were searched. The bias risk of all the literatures included in the study was evaluated by Revman 5.3 software, and the data were processed and analyzed by Stata 16.0 software. The standardized mean difference ( SMD) was calculated for the difference of efficacy indexes, and the difference was compared by t- test. The odds ratio ( OR) was calculated for the difference of safety in-dex, and the difference was compared by t- test. Results:①A total of 7 relevant research literatures were in-cluded, all of which were in English. ②A total of 675 patients were included in the study, of which 330 patients were treated with intra-articular injection of platelet rich plasma and hyaluronic acid, and 345 patients were treated with intra-articular injection of platelet rich plasma only. ③The VAS scores of patients with platelet rich plasma and hyaluronic acid injection combined with injection and platelet rich plasma injection alone were compared. After 1 and 3 months of injection, the VAS scores of patients with platelet rich plasma combined with hyaluronic acid injection were compared with those of patients with platelet rich plasma injection only. There was no significant difference[ SMD(95% CI)=-0.02(-0.30, 0.27), t=-0.12, P=0.902; SMD(95% CI)=-0.40(-0.80, 0.00), t=-1.97, P=0.051]. After 6 months of injection, the VAS scores of patients with combined injection of platelet rich plasma and hyaluronic acid were significantly lower than those of patients with injection of platelet rich plasma only, and the difference was statistically significant [ SMD(95% CI)=-0.33 (-0.55, -0.11), t=-2.98, P=0.012]. ④The WOMAC scores of patients with combined injection of platelet rich plasma, hyaluronic acid and platelet rich plasma only were compared. After 12 months of treatment, the WOMAC scores of patients with combined injection of platelet rich plasma and hyaluronic acid were significantly higher than those of patients with PRP only, and the difference was statistically significant [ SMD(95% CI)=-0.30(-0.58, -0.03), t=-2.14, P=0.033]. ⑤The incidence of adverse events of platelet rich plasma combined with hyaluronic acid was lower than that of platelet rich plasma only [ OR(95% CI)=0.55(0.33, 0.93), P=0.021]. Conclusion:Compared with intra-articular injection of platelet rich plasma only, the short-term clinical efficacy of combined injection of platelet rich plasma and hyaluronic acid is equivalent to that of injection of platelet rich plasma only, but the long-term clinical efficacy is significantly better, and the safety of combined injection of platelet rich plasma and hyaluronic acid is significantly better.

Objective: To investigate the occurrence and risk factors of deep venous thrombosis (DVT) in adult burn patients. Methods: The clinical data of 1 219 adult burn patients admitted to the Department of Burns of Zhengzhou First People′s Hospital from January 1, 2015 to August 31, 2016, conforming to the study criteria, were analyzed retrospectively by the method of case-control study, including 811 males and 408 females, aged 18-102 years. According to whether DVT occurred during hospitalization or not, the patients were divided into group DVT (n=12) and non-DVT group (n=1 207). The incidence of DVT, the diagnosis time of DVT, affected limbs, and DVT classification were counted and recorded. The gender, age, total burn area, D-dimer, lower limb burn, full-thickness burn, femoral vein indwelling central venous catheter (CVC) , inhalation injury, sepsis/infection shock, surgical operation, and infusion of concentrated red blood cells of patients between the two groups were compared with chi-square test, and then the indicators with statistically significant differences between the two groups were processed by multivariate binary logistic regression analysis to screen the independent risk factors of DVT in the adult burn patients. Results: (1) The incidence of DVT of adult burn patients was 0.98% (12/1 219), and DVT was diagnosed 24-138 days after injury, with a median of 61.5 days. DVT occurred in the right lower limb of 2 patients, left lower limb of 8 patients, and bilateral lower limbs of 2 patients, and DVT classification included 6 cases of mixed type and 6 cases of peripheral type. (2) There were no statistically significant differences in gender, age, and full-thickness burn of patients between the two groups ( χ²=1.524, 0.021, 3.115, P>0.05). There were statistically significant differences in total burn area, lower limb burn, inhalation injury, sepsis/infection shock, D-dimer, femoral vein indwelling CVC, surgical operation, and infusion of concentrated red blood cells among patients between the two groups (χ²=17.975, 6.206, 3.987, 8.875, 5.447, 15.124, 10.735, 14.031, P<0.05 or P<0.01). (3) Total burn area, D-dimer, and femoral vein indwelling CVC were independent risk factors for DVT in adult burn patients (odds ratio=10.927, 4.762, 9.394, 95% confidence interval=3.078-38.789, 1.197-18.934, 2.631-33.540, P<0.05 or P<0.01). Conclusions The incidence of DVT in adult burn patients is relatively low, and the diagnosis time of DVT is 3 weeks after burn, with DVT classification of mixed type and peripheral type. The total burn area, femoral vein indwelling CVC, and D-dimer are independent risk factors for predicting DVT in adult burn patients.

Objective:To explore the risk factors related to hospitalization events in out patients on hemodialysis and to evaluate the effect of serum retinol-binding protein (RBP) level on hospitalization events in patients on hemodialysis.Methods:Case-control study. A total of 80 patients on dialysis were recruited, including 47 men (58.8%) and 33 women (41.2%), with an average age of (60.9±11.7) years (range: 32-89 years) and a median dialysis age of 43.6 months. Dialysis-related data were collected, the serum RBP level was detected using the ELISA method. Patients were followed-up until June 30, 2019, to record the events associated with all kinds of hospitalization events. The t-test, Mann-Whitney U test and chi-square test were used to compare the differences between the hospitalized event group and the non-event group. Multivariate logistic regression was used to analyze the related risk factors of hospitalization events. The Kaplan-Meier method, Log-rank test, and Cox proportional hazards regression model were used to analyze survival data. Results:During the 19-month follow-up period, 26/80 patients (32.5%) had 67 events of hospitalization. There was no difference ( P>0.05) in age, sex composition, dialysis age, ratio of diabetes/hypertension, interval dialysis weight gain (IDWG), systolic/diastolic blood pressure before dialysis, kt/v and URR between the groups with or without hospitalization events. The cut-off point of serum RBP was calculated using the patient′s highest Youden index. The patients were divided into the high-RBP group ( n=44) and low-RBP group ( n=36) according to the level of 165.34 mg/L. The incidence of hospitalization events in the high-RBP group was higher than that in the low-RBP group (45.45%>16.67%, P=0.006). Using the multivariate logistic regression model, after adjusting for sex, age, albumin and total cholesterol (CHO), only the serum RBP level was independently correlated with hospitalization events. The high-RBP group had an odds ratio ( OR) of 3.64 (95 %CI, 1.14-11.58; P=0.029) compared with the low-level group in hospitalization events. The Kaplan-Meier survival analysis showed that the incidence of hospitalization events in the high-RBP group was significantly higher than that in the low-RBP group ( P=0.0058). The test results of the multivariable Cox proportional hazards regression model showed that for patients on hemodialysis, an elevated serum RBP level is an independent risk factor for hospitalization events. Conclusion:Elevated serum RBP level is correlated with hospitalization events in patients on hemodialysis. RBP is an independent risk factor for hospitalization events in outpatients on hemodialysis.
