Adolescents and young adults (AYAs) are one of the major populations susceptible to tuberculosis. However, little is known about the unique characteristics and diagnostic biomarkers of tuberculosis in this population. In this study, 81 AYAs were recruited, and the high-quality serum proteome of the AYAs with tuberculosis was profiled by quantitative proteomics. The data of serum proteomics indicated that the relative abundance of hemoglobin and apolipoprotein was significantly reduced in the patients with active tuberculosis (ATB). The pathway enrichment analysis showed that the downregulated proteins in the ATB group were mainly involved in the antioxidant and cell detoxification pathways, indicating extensive oxidative stress damage. Random forest (RF) and extreme gradient boosting (XGBoost) were employed to evaluate protein importance, which yielded a set of candidate proteins that can distinguish between ATB and non-ATB. The analysis with the support vector machine algorithm (recursive feature elimination) suggested that the combination of apolipoprotein A-I (APOA1), hemoglobin subunit beta (HBB), and hemoglobin subunit alpha-1 (HBA1) had the highest accuracy and sensitivity in diagnosing ATB. Meanwhile, the levels of hemoglobin (HGB) and albumin (ALB) can be used as blood biochemical indicators to evaluate changes in the protein levels of APOA1 and HBB. This study established the serum proteome landscape of AYAs with tuberculosis and identified new biomarkers for the diagnosis of tuberculosis in this population.

Objective:To explore the suitable prostate cancer screening mode under the medical community for primary hospitals.Methods:From April 2021 to April 2022, a total of 16007 male population ≥50 years from 9 branches of the medical community of the second hospital of Yinzhou participated in this study. They were divided into four groups according to age with group 1 of 50-59 years old, group 2 of 60-69 years old, group 3 of 70-79 years old, and group 4 of 80 years old and above. Serum tPSA was added to the routine physical examination, and the screening positive patients were referred to the referral hospital for further diagnosis and treatment under the mode of medical community. We proposed multi-parametric MRI (mpMRI) for those with serum PSA ≥4 ng/ml and suspicious lesions should be scored according to PI-RADS V2. The ultrasound-guided transperineal targeted prostate biopsy was performed for those with PI-RADS ≥3 and those with PI-RADS < 3 but tPSA ≥10 ng/ml. The tPSA follow-up examinations were performed every 6 months for tPSA < 10 ng/ml and PI-RADS < 3 points and once a year for tPSA < 4 ng/ml.Results:Among the 16 007 male population ≥50 years, 2 007(12.54%) were found serum PSA ≥4 ng/ml, and 634(31.59%)were referred to the referral hospital through the medical community system. Combining tPSA and mpMRI, 271 patients underwent ultrasound-guided transperineal targeted prostate biopsy. Among them, 162 were finally diagnosed with PCa, with a biopsy positive rate of 59.78%. The detection rate of PCa in all the subjects was 1.01%. According to the pathological grade, 5(3.08%) were in ISUP group 1, 95(58.64%) in ISUP group 2-3, and 62(38.27%) in ISUP group 4-5. There were 102(62.96%), 39(24.07%) and 21(12.96%) with localized, locally advanced or metastatic PCa, respectively. The levels of tPSA in the four groups were (1.13±1.44)ng/ml, (1.77±3.45)ng/ml, (3.27±17.58)ng/ml, and (4.26±11.48)ng/ml, respectively, with statistically significant differences ( P<0.01). The positive number of biopsy in each group was 1 case(0.06%), 56 cases(0.79%), 81 cases(1.36%) and 24 cases(1.82%) respectively, with statistically significant differences ( P<0.01). The number of ISUP 4-5 grades in each group was 0, 17(30.35%), 29(35.80%), and 16(66.67%) respectively, with statistically significant differences ( P<0.01). Conclusions:Based on the medical community system, according to the tPSA screening results of the primary hospitals, it is feasible and effective to refer suspicious patients to the referral hospitals for mpMRI examination, and screen prostate cancer by ultrasound-guided transperineal prostate fusion biopsy.

This article discusses an education model that aims to contribute to students' growth and success and develop students' knowledge, abilities, and values based on the concept of outcome-based education (OBE). Under the guidance of this concept, measures have been taken from multiple dimensions, such as adopting a student-centered approach in theory course teaching, forming a team of teaching assistants, strengthening curriculum ideology and politics, optimizing curriculum content design, reforming teaching methods and teaching platforms, and enhancing feedback to teaching. Rehabilitation medicine courses taught with the OBE concept achieved better outcomes than those taught with conventional approaches adopted in the previous years, with satisfaction, acceptance, and recognition rates of higher than 95% among the students, as well as higher excellent and good rates in the end-of-semester tests compared with those of the same course last year. The preliminary exploration of the teaching reform under this model has provided reference for improving the quality of rehabilitation medicine teaching and cultivating modern professional talents in rehabilitation medicine.

Objective: To investigate the correlation of carriage and expression of quorum sensing(QS) system regulatory genes and virulence genes with drug resistance inPseudomonas aeruginosastrains isolated from clinical sources. Methods: A total of 97 strains ofPseudomonas aeruginosaisolated from various clinical specimens in the laboratory were collected. Firstly, Drug-resistance were detected by the vitek2-compact instrument method and the standard disc diffusion method, 4 QS system-regulated genes and 7 virulence genes were detected by polymerase chain reaction(PCR). After that, the expression of regulatory genes LasI, Rh1 R and virulence genes exoS and PCN were detected by real-time fluorescence quantitative PCR(qRT-PCR), and moreover linearly analysis was used to analyze the correlation of the two types of genes. Results: The resistance rates of 97 strains to 11 antibacterial drugs. The resistance rate of tobramycin, gentamicin, and amikacin was less than 10%, and the minimum amikacin was 2.06%. The resistance rate to the remaining drugs was all above 11%, and the highest was imipenem 25.77%, and 43 strains were multi-drug resistant bacteria, and the respiratory-derived strains were more resistant to antimicrobials. The results of PCR gene detection showed: the detection rates of the four QS system-regulated genes LasI, LasR, Rh1 I and Rh1 R were all 100%; the highest detection rate of 7 virulence genes was exoT 98.97%(96/97),and the lowest was exoU 13.40%(13/97),PCN 43.30%(42/97),and the rest were above 86%. The strains without virulence genes were resistant to 6 antibiotics including ceftazidime, and the strains with 7 virulence genes were only resistant to ceftazidime; among the PCN, exoS, and exoU positive strains, the proportion of non-multidrug resistantPseudomonas aeruginosa(NMDR-PA)was higher; PCN+ strains were more resistant to piperacillin/tazobactam and the difference was statistically significant; compared with exoS+/exoU-strains, the types of antibiotics resistant to exoS-/exoU+ strains decreased significantly. The relative expression levels of regulatory genes rh1 R and LasI in NMDR-PAwere higher and the difference of LasI was statistically significant; the expression of the regulatory gene rh1 R and the virulence gene exoS and the regulatory gene LasI and the virulence gene PCN showed a positive linear relationship. Conclusion The drug-resistance ofPseudomonas aeruginosais still serious and multi-drug resistance. QS system regulatory genes exist in the strain stably, except for exoU and PCN, the other virulence genes exoS, exoT, exoY, ToxA and LasB have higher carrying rates, the regulatory genes rh1 R and LasI positively regulate the expression of virulence genes, both QS system regulatory genes and virulence genes affect drug resistance inPseudomonas aeruginosa.

ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） external therapeutic protocol of enriching pus for tissue growth （EPTG） in the treatment of Wagner 2-3 diabetic foot ulcer. MethodThe randomized controlled trial （RCT） design was adopted. Patients receiving basic treatment were divided into the EPTG group and the control group （debridement and change of nano-silver medical antibacterial dressing）. Ulcer healing rate， ulcer area， ulcer depth， TCM symptom score， visual analogue scale（VAS）， transcutaneous partial pressure of oxygen， wound blood flow， inflammatory factors ［C-reactive protein （CRP）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α）］， growth factors ［vascular endothelial growth factor （VEGF）， transforming growth factor-β₁ （TGF-β₁）， and fibroblast growth factor-β （FGF-β）］， adverse events， and outcome events of the two groups before and after treatment were observed. ResultCompared with the conditions before treatment， the ulcer healing rate， ulcer area， ulcer depth， TCM symptom score， VAS score， transcutaneous partial pressure of oxygen， wound blood flow， CRP， IL-6， TNF-α， VEGF， TGF-β₁， and FGF-β were significantly improved （P<0.01）. In terms of the improvement in the ulcer healing rate， ulcer area， ulcer depth， VAS score， transcutaneous partial pressure of oxygen， wound blood flow， CRP， IL-6， TNF-α， VEGF， TGF-β₁， and FGF-β， the EPTG group was superior to the control group （P<0.01）. There were no statistically significant differences in adverse events and outcome events between the two groups. ConclusionThe TCM external therapeutic protocol of EPTG is safe and effective in the treatment of Wagner 2-3 diabetic foot ulcer. It can greatly reduce the area and depth of diabetic foot ulcer， improve the ulcer healing rate and TCM symptom score， relieve the pain of patients， and improve the microcirculatory blood supply in the local ulcer. Its mechanism of action may be related to the reduction of the local inflammatory response of the wound and the improvement of the proliferation of fibroblasts and vascular endothelial cells.

In order to compare the setting of difference coefficients in DRG point payment in different cities in Zhejiang province, the implementation rules of DRG point payment issued by 11 cities in Zhejiang province were comprehensively analyzed. It was found that the difference coefficients in different cities could be divided into three categories, including hospital coefficients alone, hospital coefficients and grade coefficients weighted, and weighted by hospital coefficients, grade coefficients, personal burden levels, case mix indexes, and head-to-time ratio. Its setting differences included four aspects: connotation composition, weight distribution, threshold value, and classification of medical institutions. The authors suggested that the adjustment cycle should be set scientifically to dynamically adjust the difference coefficient, and the scientific setting of the difference coefficient should be promoted through provincial coordination.

Objective: To verify the diagnostic value of adenosine deaminase (ADA) for tuberculous pleural effusion. Methods: Forty-three cases with tuberculous pleural effusion and 163 cases with non-tuberculous pleural effusion were consecutively collected. The concentration of ADA in pleural effusion was determined by enzyme kinetics. The receiver operating characteristic (ROC) analysis curve was used to calculate the optimal cut-off value of ADA for diagnosing tuberculous pleural effusion based on the control groups with non-tuberculous pleural effusion. Meanwhile, the specificity and sensitivity of ADA level for diagnosis of tuberculous pleural effusion were compared with previous reports. Results: The concentration of ADA in tuberculous pleural effusion (median 52.5 U/L) was significantly higher than that in non-tuberculous pleural effusion (median 9.8 and 10.6 U/L) (P＜0.05). With a cut-off level for ADA of 25 U/L, the diagnostic sensitivity and specificity was 88.0% and 91.0%, respectively. A system review analyzed data from 17 studies with QUADAS score ≥10 points and revealed the cut-off value of ADA to be （28.1±12.8） U/L (range 10.2 to 55.8 U/L) with a sensitivity of 89% (95%CI: 87% to 91%) and a specificity of 89% (95%CI: 88% to 91%). Conclusion The specificity and sensitivity of ADA for diagnosis of tuberculous pleural effusions should be up to over 85%, while the cut-off value of ADA from different literature reports were diverse.
