Objective:To investigate the clinical efficacy and safety of needle-free and needle-based injections of recombinant human interferon (IFN) -α2a in the treatment of palmoplantar warts.Methods:Patients aged 6 to 75 years with palmoplantar warts were prospectively enrolled from the Department of Dermatology, Zhongda Hospital, Southeast University between March and September 2023, and baseline data were collected. The patients were randomly and equally divided into a needle-free injection group and a needle-based injection group by using a random number table method, and received needle-free and needle-based injections of recombinant human IFN-α2a once every 2 to 3 weeks, respectively, with a maximum of 4 treatment sessions. Efficacy was assessed based on changes in wart size and skin lines under a dermoscope. Pain degrees and adverse reactions were recorded, and patients were followed up for 6 months after the end of treatment. Chi-square test was used to compare the cure rates, recurrence rates, and incidence rates of adverse reactions between the two groups. Logistic regression analysis was employed to identify factors related to the clearance of palmoplantar warts.Results:A total of 160 patients with palmoplantar warts were included, with 80 patients in each group. In the needle-free injection group, there were 45 females (56.2%) and 35 males (43.8%) ; their ages ( M[ Q1, Q3]) were 27 (23, 40) years, and the duration of disease ( M[ Q1, Q3]) was 12 (3, 24) months; warts were located on the hands in 12 cases (15.0%), on the feet in 60 cases (75.0%), and on both sites in 8 cases (10.0%) ; warts measuring ≤ 1 cm in diameter were observed in 71 cases (88.8%), and those measuring > 1 cm were observed in 9 cases (11.3%). In the needle-based injection group, there were 37 females (46.2%) and 43 males (53.8%) ; their ages were 28 (22, 39) years, and the duration of disease was 6 (2, 12) months; warts were located on the hands in 23 cases (28.7%), on the feet in 55 cases (68.8%), and on both sites in 2 cases (2.5%) ; warts measuring ≤ 1 cm in diameter were observed in 67 cases (83.8%), and those measuring > 1 cm in diameter were observed in 13 cases (16.3%). There were no significant differences in gender distribution, age, wart diameters, prior treatment status, or number of warts between the two groups (all P > 0.05). The duration of disease was longer in the needle-free injection group than in the needle-based injection group ( P = 0.041), and the dose of interferon was lower in the needle-free injection group than in the needle-based injection group ( P < 0.001). After treatment, 44 patients (55.0%) were cured in the needle-free injection group, and 39 (48.8%) in the needle-based injection group, with no significant difference in the cure rates between the two groups ( χ2 = 0.63, P = 0.429). Among patients with multiple warts, 54.8% (23/42) were cured in the needle-free injection group, and 47.4% (18/38) in the needle-based injection group, with no significant difference in cure rates between the two groups ( χ2 = 1.28, P = 0.509). The most common adverse reaction was fever or flu-like symptoms (186 instances), which resolved spontaneously in 141 instances and resolved after treatment with oral ibuprofen in 45 instances; the incidence rate of flu-like symptoms was significantly lower in the needle-free injection group (57 instances, 21.6%) than in the needle-based injection group (129 instances, 53.3%; χ2 = 54.63, P < 0.001). The pain score was significantly lower in the needle-free injection group (3.65 ± 1.25 points) than in the needle-based injection group (5.16 ± 1.17 points, t = -7.90, P < 0.001). The logistic regression analysis showed that the duration of disease, lesion sites, patient age, and previous treatment history had no impact on the efficacy in either the needle-free injection group or the needle-based injection group (all P > 0.05) . Conclusions:The efficacy of needle-free and needle-based injections of interferon was similar in the treatment of palmoplantar warts, whereas needle-free injections resulted in less pain and a lower incidence of interferon-related adverse reactions. None of the duration of disease, lesion sites, patient age, or prior treatment status showed significant impact on the efficacy in the two groups.

Left ventricular assist device (LVAD) serves as a critical therapeutic option for patients with end-stage heart failure, significantly enhancing survival rates and quality of life. However, LVAD implantation exerts complex and profound effects on right ventricular (RV) function, with RV dysfunction emerging as a key factor influencing the prognosis of LVAD patients. This article systematically reviews the relationship between LVAD and RV function, exploring the importance of RV function in LVAD patients, assessment methods, underlying mechanisms of impact, and strategies for prevention and management. Comprehensive evidence suggests that preoperative evaluation of RV function is crucial for predicting the risk of RV dysfunction, while effective prevention and management rely on preoperative optimization, meticulous intraoperative techniques, rigorous postoperative monitoring, and multidisciplinary collaboration. Furthermore, this review discusses the potential and future directions of emerging technologies, such as improved LVAD designs, biventricular assist devices, gene therapy, and personalized medicine, in ameliorating RV dysfunction. In conclusion, RV function is one of the key determinants of successful LVAD therapy. Through comprehensive assessment, prevention, and management of RV function, coupled with the application of novel technologies, the clinical outcomes of LVAD patients can be further improved.

Abstract Depression is a major public health issue among adolescents. The Ministry of Education of China recently proposed to integrate depression screening into students school health check among adolescents. However, there are inconsistencies regarding the strength of recommendation and implementation details of routine screening for adolescent depression across professional organizations and countries. This paper outlines the epidemiology and risk factors of adolescent depression and summarizes relevant international guidelines and recommendations. We suggest that before the national implementation of school based depression screening, key issues including scientific evidence, execution details, resource allocation and ethical considerations need to be examined in close collaboration with all stakeholders. Systematic piloting followed by rigorous evaluation will also be needed.

OBJECTIVE:To review the practicality and effectiveness ofReady-to-useextended mobile Baxter intravenous ad-mixture service(BIVAS)in the application of intravenous medication centralized deployment services. METHODS:Combined with the requirements of Intravenous Admixture Centralized Deployment and Quality Management Practices,and the present establish-ment and management characteristics in pharmacy intravenous admixture services (PIVAS) in our hospital,the development and management methods of BIVAS each link were introduced and summarized from pre-building to post-trial operation. RESULTS &CONCLUSIONS:Specific measures and methods for developing BIVAS in our hospital were introduced from aspects of assess-ment,site selection,building,research,staffing and operation,etc. It had proved that BIVAS can achieve a daily compoundingload of about 600 bags in 8 wards of eastern branch of our hospital. Since BIVAS holds advantages in sterile dispensing equipment and technology that is comparable to PIVAS,and lower space requirements,shorter building periods,more flexible combination, less occupation of funds and other health resources as well as more convenient post-maintenance,it can take the place of PIVAS to effectively complete intravenous drug deployment services under general workload with certain practicality when a hospital couldn't build PIVAS limited by building funds,venues,time and other factors.

RESULTS:It was quality key point that total length of temporary medical order ad-mixture which included injection sequence,label checking,preparation,package rechecking,drug distribution and so on,was con-trolled within 120 min;through formulating and implementing various measures as improving information system,adjusting prepa-ration sequence and shunting staff posts flexibly,the total time of first 3 batches of temporary order admixture were 120,98 and 77 min after improvement,shortening by about 30,50 and 55 min respectively,compared with before improvement (P<0.05). CONCLUSIONS:The six sigma method has shortened the time of temporary order medical admixture in our hospital. The formulat-ed measures are effective and feasible.

OBJECTIVE: To establish reference values of acoustic rhinometry, rhinomanometry and rhinospirometer in healthy adults in Tianjin area, analyze the effects of age,sex and side on the value, investigate the correlation of the measure values, offer the diagnosis date for test nasal ventilation function in Tianjin area. METHOD: Four hundred and sixty-six healthy adults in Tianjin area were tested. A1 acoustic rhinometry was used to measure the minimum cross-sectional area (MCA), distance of the minimal cross-sectional area to the nostril (DCAN) and the nasal volume from 0-5 cm, 2-5 cm (V5, V2-5); At 150 Pa, 75 Pa and broms, NR6 Rhinomanometry was used to measure unilateral nasal inspiratory resistance (IR)and expiratory resistance (ER), bilateral nasal inspiratory and expiratory resistance (TIR and TER), and differences of the bilateral nasal resistance can be calculated; NV1 Rhinospirometer was used to measure unilateral inspiratory capacity (IC) and expiration capacity (EC), and the nasal partitioning ratio (NPR) can be calculated. Practical measure the distance of nostril to ahead of the inferior turbinate and compare with DCAN. Make the correlational analysis on different index of three exam. RESULT: Reference values of acoustic rhinometry: MCA was (0.45 +/- 0. 16) cm2 for male, (0.44 +/- 0.16) cm2 for female; V2-5 was (3.52 +/- 1.38) cm3 for male, (3.36 +/- 1.22) cm3 for female, V5 was (5.10 +/- 1.47) cm3 for male, (4.86 +/- 1.12) cm3 for female; DCAN have two distance, (2.22 +/- 0.398, 0.53 +/- 0.625) cm was for male, (2.10 +/- 0.37, 0.67 +/- 0.15) cm was for female. No significant gender, side and age differences were shown in MCA, V5, V2-5. Significant gender differences were shown in DCAN but no side and age differences. Reference values of rhinomanometry: Significant gender but no side and age differences were shown in IR, ER, TIR, TER. Reference values of rhinospirometer: IC was (2.06 +/- 1.10) L/20 s for male, (1.37 +/- 0.34) L/20 s for female, EC was (2.15 +/- 1.23) L/20 s for male (1.39 +/- 0.58) L/20 s for female. NPRi was 0.11 [0.05, 0.23],NPRe was 0.11 [0.05, 0.19]. Significant gender but no side and age differences were shown in IC and EC. No gender and age differences were shown in NPRi and NPRe. There was significant correlation found between MCA and IR/ER/IC/EC, IR and IC, ER and EC, Rlr and NPRi/ NPRe. CONCLUSION Acoustic rhinometry,rhinomanometry and rhinospirometer can be useful reference values to evaluate nasal ventilation function, more value will be found if use the three together.
