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.

Objective:To search for and summarize the best evidence on non-pharmacological interventions for orthostatic hypotension in patients with Parkinson disease.Methods:Based on the 6S model, the relevant guidelines, clinical decisions, evidence summaries, systematic reviews and expert consensus on non-pharmacological interventions for orthostatic hypotension in Parkinson disease patients were systematically retrieved from domestic and foreign databases. The search time was from the establishment of the database to December 2022. Two researchers independently screened the literature, evaluated the quality of the included literature, and extracted and summarized evidence that met the quality standards.Results:A total of 15 articles were included, including 4 guidelines, 2 clinical decision-making articles, 1 evidence summary article, 3 systematic evaluations and 5 expert consensus articles. A total of 24 pieces of best evidence were summarized from 7 aspects, including purpose, evaluation, capacity intervention, exercise intervention, posture intervention, physical intervention, health education and support.Conclusions:The best evidence on non-pharmacological intervention for orthostatic hypotension in patients with Parkinson disease can provide a reference for the practice of clinical medical staffs. It is suggested to apply the best evidence in combination with the patient's condition, preference and clinical environment, so as to reduce the incidence of orthostatic hypotension in patients with Parkinson disease and to ensure the safety of patients.

Objective:To explore the effects of 5E rehabilitation nursing model on self-management behavior and fatigue symptoms of patients with chronic obstructive pulmonary disease (COPD) .Methods:Totally 110 COPD patients admitted in Yantai Yuhuangding Hospital from October 2018 to September 2019 were selected by convenient sampling, and divided into the control group ( n=53) and the experimental group ( n=57) according to the random number table. Excluding missing patients and patients with incomplete data, finally 48 patients were included in the control group and 51 patients were included in the experimental group. Patients in the control group received routine care and health guidance, while patients in the experimental group received care based on the 5E rehabilitation nursing model. The Self-Management Scale for COPD Patients and the Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F) were used to evaluate the effects of interventions in the two groups. Results:There was no statistically significant difference in the scores of the Self-Management Scale between the two groups before intervention ( P>0.05) ; the scores of all dimensions the Self-Management Scale of the experimental group were higher than those of the control group 12 weeks after discharge, and the differences were statistically significant ( P<0.05) . There was no statistically significant difference in fatigue scores between the two groups before intervention and 12 weeks after discharge ( P>0.05) . Conclusions:The 5E rehabilitation nursing model can improve the self-management behavior of COPD patients, but it cannot ameliorate the fatigue symptoms of patients. Large-sample, multi-center, and long-term research will be further needed in the future to explore the effects of the 5E rehabilitation nursing model on patients' fatigue symptoms.

Objective: To investigate the mechanisms of miR-375 affecting the proliferation and invasion of hepatoma cells via targeting YAP (Yes-associated protein). Methods: The cancerous tissues and corresponding para-cancerous tissues of 70 patients with hepatocellular carcinoma (HCC) who underwent surgical resection at the Second Affiliated Hospital of Henan University of Traditional Chinese Medicine from January 2015 to December 2016, as well as the hepatoma cell lines SMMC-7721, Hb611, HepG2 and BEL-7405 were collected for this study. qPCR method was used to detect the expression level of miR-375 in collected HCC tissues and different hepatoma cell lines; Dual luciferase reporter gene assay was used to verify the interaction between miR-375 and YAP; The relationship between miR-375 and clinicopathological features of HCC patients was also analyzed; MTT assay was used to detect the effect of miR375 on the proliferation of hepatoma cells; Transwell invasion assay was used to detect the invasive ability of hepatoma cells after inhibiting the expression of miR-375; Western blotting was used to detect the expression of YAP in HepG2 cells. The nude mouse model of subcutaneously transplanted xenograft was established, and the tumor volume and mass of transplanted hepatoma cells were detected after inhibiting the expression of miR-375. The expression of YAP in xenograft of nude mice was detected by immunohistochemistry and Western blotting. Results: The expression of miR-375 and YAP in HCC tissues was significantly higher than that in para-cancerous tissues (all P<0.05). The expression of miR-375 in HepG2 cells was the highest (P<0.05). miR-375 could specifically bind to the 3' UTR of YAP and regulate the expression activity of YAP. After inhibiting the expression of miR-375, the proliferation and invasion abilities of HepG2 cells were reduced (all P<0.05); The tumor volume and mass of transplanted xenografts were significantly reduced (both P<0.05); The expression of YAP protein in the transplanted xenografts was down-regulated (P<0.05). Conclusion: miR-375 plays an important role in the occurrence and development of liver cancer, and can influence the malignant biological behaviors of hepatoma cells by targeting and regulating the expression ofYAP.

Background Macular edema is one of the serious complications of central retinal vein occlusion (CRVO),and the present therapies are laser coagulation and intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs.Conbercept is humanized-monoclonal VEGF antibody and used for the treatment of retinal vascular diseases.However,fewer studies were focused on its application in macular edema secondary to CRVO.Objective The aim of this study was to compare the effectiveness and safety of conbercept with triamcinolone acetonide(TA)by intravitreal injections for macular edema secondary to CRVO. Methods A non-randomized controlled study was carried out under the approval of the informed consent of patients.Sixty eyes of 60 patients with macular edema secondary to CRVO were included in Weifang Yidu Central Hospital from March 2012 to August 2013.The eyes were divided into the conbercept group and TA group with 30 for each group.Conbercept and TA of 0.05 ml were intravitreally injected in different groups,and the best corrected visual acuity(BCVA),central macular thickness(CMT)measured by OCT,intraocular pressure(IOP)and relavant complications were examined before injection and 1 week,1 month,3 months and 6 months after injection.The treatment outcomes were compared intergrouply and along with time. Results The BCVA was evidently better in 1 week,1 month,3 months and 6 months after injection than that before injection both in conbercept group and TA group(all at P＜0.01),and the BCVA of TA group was better than that of conbercept group 1 week after injection(P＜0.05).The CMT values of Conbercept were(572.00± 100.01),(325.12±91.55),(280.00±92.37),(258.65 ±88.65),(300.00±87.64)μm,and those of TA group were(570.00± 102.21),(345.12±89.31),(290.00±80.27),(309.65 ±84.13)and(303.00±90.59)μm,and CMT value after injection was significantly lower in 1 week,1 month,3 months and 6 months after injection than that before injection both in the conbercept group and the TA group(all at P＜0.05),and CMT value was evidently reduced in the conbercept group compared with the TA group 3 months after injection(P＜0.05).The IOP was(15.20±3.52),(21.20±3.80),(26.40±4.00),(23.60±3.73)and(21.50±3.27)mmHg in the TA group before injection and 1 week,1 month,3 months and 6 months after injection,showing significnatly elavation after injection(all at P＜0.05),and the IOP at different time points was higher in the TA group than that in the conbercept group(all at P＜0.05).However,there was no considerable change of IOP before and after injection in conbercept group(all at P＜0.05). Conelutions Both conbercept and TA are effective for macular edema secondary to CRVO by intravtreal injection.Compared with TA,conbercept is much safer because of less risk of IOP rising after intravtreal injection.
