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 explore the relationship between the expression of peripheral blood interleukin-17 (IL)-17 and IL-8 and the short-term prognosis of sepsis patients.Methods:The data of 158 patients with sepsis admitted to Huzhou Central Hospital from January 2020 to January 2024 were retrospectively collected. The patient′s data were carefully reviewed, and the results of the study were recorded, including the severity of the patient′s condition (138 cases of sepsis, 20 cases of septic shock), baseline data, and short-term prognosis (28-day mortality). The levels of procalcitonin (PCT), peripheral blood IL-17, IL-8, and other laboratory indicators were compared between patients with different severity and different prognosis. COX regression model analysis and interaction test were used to verify the relationship between peripheral blood IL-17, IL-8 levels, and short-term prognosis in patients with sepsis. The receiver operating characteristic (ROC) curve was drawn and the decision curve was constructed to analyze the predictive value of peripheral blood IL-17 and IL-8 levels on the short-term prognosis of patients with sepsis.Results:The levels of IL-17 and IL-8 in the peripheral blood of patients with different severity of sepsis at admission were higher in the septic shock group than those in the sepsis group: (82.48 ± 13.54) μg/L vs. (62.84 ± 12.09) μg/L, (41.80 ± 5.46) ng/L vs. (34.22 ± 6.77) ng/L,( P<0.05). The acute physiology and chronic health evaluation (APACHE) Ⅱ score, PCT, IL-17, and IL-8 levels at admission in the death group were higher than those in the survival group, and the proportion of patients with septic shock was higher than that in the survival group: (12.09 ± 2.06) points vs. (10.81 ± 2.36) points, (2.23 ± 1.18) μg/L vs. (1.78 ± 0.69) μg/L, (79.24 ± 13.72) μg/L vs. (61.37 ± 11.15) μg/L, (42.43 ± 5.07) ng/L vs. (33.09 ± 6.14) ng/L, 51.43%(18/35) vs. 1.63%(2/123), P<0.05. COX regression analysis showed that the short-term prognosis of patients with sepsis was related to the abnormal expression of IL-17 and IL-8 in peripheral blood. The high expression of both may be a risk factor for the short-term prognosis of patients with sepsis ( P<0.05). The levels of IL-17 and IL-8 in peripheral blood had a positive interaction on the short-term prognosis of patients with sepsis. The risk of death when both were highly expressed was 97.500 times that when both were lowly expressed and the synergistic effect was 9.362 times higher than the sum of the effects produced by the two alone (synergy index = 9.362). ROC curve was drawn to obtain the area under the curve (AUC). The AUC of peripheral blood IL-17, IL-8 alone and combined to predict the short-term prognosis risk of sepsis patients were 0.839, 0.889 and 0.960, respectively, which had ideal predictive value, and the combined predictive value was higher than that of the two alone ( Z = 3.85, 2.66, P<0.05). The decision curve was drawn. When the threshold was 0.1-1.0, the net return rate of the combined prediction model of IL-17 and IL-8 in peripheral blood to predict the short-term prognosis risk of sepsis patients was better than that of IL-17 and IL-8 alone, and the maximum net return rate was 0.222. Conclusions:The more severe the condition of sepsis patients, the higher the expression of IL-17 and IL-8 in peripheral blood, which may suggest that patients have a high risk of short-term death. Early combined detection of IL-17 and IL-8 levels in the peripheral blood of sepsis patients can predict their short-term prognostic risk.

Objective To analyze the development trajectory and predictors of endocrine therapy associated arthralgia in breast cancer patients.Methods From January 2022 to July 2022,breast cancer patients in the breast medicine department or outpatients of a tertiary cancer hospital in Hunan Province were selected as respondents using a convenience sampling method.A baseline survey was conducted using the General Information Questionnaire,the Symptom Assessment Scale for Patients Treated with Endocrine Therapy for Breast Cancer,and the Self-Rating Anxiety Scale within 1 week prior to patient treatment.The Symptom Assessment Scale for Patients Treated with Endocrine Therapy for Breast Cancer was used to assess patients'arthralgia levels at 3,6,and 9 months after treatment,and data were analyzed using growth mixed model,univariate analysis of variance,and multiple logistic regression.Results A total of 418 breast cancer patients completed the follow-up,with 235 cases(56.22%)developing arthralgia.3 potential categories of arthralgia develop-ment trajectories were identified:high level-slowly increasing group(11.48%),low level-slowly increasing group(44.74%),and asymptomatic group(43.78%).The results of multifactorial analysis showed that anxiety,history of bone and joint disease,sleep duration,place of residence,monthly household income,and frequency of exercise were predictors of potential categories for the development of trajectory of arthralgia levels associated with endocrine therapy in breast cancer patients(P<0.05).Conclusion Arthralgia levels associated with endocrine therapy in breast cancer patients exhibit different trajec-tories,and clinical staff should emphasize the assessment and intervention of pain levels in patients with the anxiety,a history of bone and joint disease,poor sleep,poor finances,living in urban areas,and low frequency of exercise.

Objective:To explore the effect of combining hand-brain perception training with hand-brain motor training based on mirror neuron theory on the recovery of upper limb function after a stroke.Methods:A group of 105 stroke survivors with upper limb dysfunction were randomly divided into a hand-brain perception (HP) group, a hand-brain motor (HM) group, and a combination (C) group, each of 35. In addition to conventional rehabilitation treatment (including exercise therapy, occupational therapy and physical factor therapy), the HP and HM groups were given hand-brain perception training and hand-brain motor training respectively, while group C was provided with both. Before the intervention and after 4 weeks, the upper limb motor functioning of all of the participants was assessed using the simplified version of the Fugl-Meyer upper limb motor function scale (FMA-UE). Sensory functioning was quantified using the tactile Semmes Weinstein monofilament examination (SWME), and the modified Barthel index (MBI) was used to quantify the participants′ ability in the activities of daily living.Results:After the intervention the average FMA-UE, MBI and SWME scores of all three groups had improved significantly, with group C′s average FMA-UE and MBI scores significantly better than the other two groups′ averages. The average SWME score of group C was then significantly better than that of group HM.Conclusions:Hand-brain perception combined with hand-brain motor training based on mirror neuron theory can further promote the recovery of upper limb sensory and motor functioning of stroke survivors., Such therapy is worthy of clinical promotion and application.

Objective To explore the assisted reproductive strategy and influencing factors for patients undergoing frozen-thawed cycle blastocyst transfer after hysteroscopic adhesiolysis for intrauterine adhesions.Methods A total of 275 patients who underwent frozen-thawed cycle blastocyst transfer after hysteroscopic adhesiolysis for infertility reasons at the Reproductive Genetics Center of the First Affiliated Hospital of University of Science and Technology of China from January 2018 to December 2022 were included in the study.They were divided into a single blastocyst transfer group(n=182)and a double blastocyst transfer group(n=93).The clinical outcomes were analyzed and compared retrospectively between the group.Results The two groups showed no statis-tically significant differences in terms of age,day of endometrial thickness conversion,endometrial preparation method,clinical pregnancy rate,miscarriage rate,preterm birth rate,gestational week at delivery,and mode of delivery(P>0.05).The single blastocyst transfer group had significantly lower infertility duration(years)(2.43±1.64 vs.3.03±2.13,P<0.05),significantly lower AFS prognosis score(5.13±2.25 vs.5.72±2.19,P<0.05),and significantly lower multiple pregnancy rate(1.33%vs.28.57%,P<0.05),but significantly higher quality embryo rate(90.66%vs.46.24%,P<0.05),implantation rate(50.00%vs.34.41%,P<0.05),and live infant mass(g)(3236.84±565.35 vs.2976.44±692.79,P<0.05)compared to the double blastocyst transfer group.Binary logistic regression analysis showed that the number of high-quality embryos transferred and AFS score were independent influencing factors for clinical pregnancy(P<0.05).Conclusions The number of high-quality embryos transferred and the AFS score are independent influencing factors for clinical pregnancy in patients undergoing frozen-thawed cycle blastocyst transfer after hysteroscopic adhesiolysis for intrauterine adhesions.Single high-quality blastocyst transfer is a preferred treatment for patients after hysteroscopic adhesiolysis,and double blastocyst transfer is favor-able for patients with a poor prognosis to achieve better pregnancy outcomes.

Objective To observe the role of dried tangerine peel in Yigong Powder improves iron metabolism and promotes red blood cell generation in anemia of chronic disease (ACD).Methods With a two-by-two factorial design,the Yigong Powder was divided into dried tangerine peel and Chenpi absent Decoction. According to the random number table method,32 zymosan-induced generalized inflammation (ZIGI) mice were randomly divided into the model group,the dried tangerine peel group,the Chenpi absent Decoction group,and the Yigong Powder group. The dried tangerine peel group,Chenpi absent Decoction group and the Yigong Powder group were given dried tangerine peel(3.083 g/kg),Chenpi absent Decoction(12.33g/kg),and Yigong Powder(15.413g/kg)by gavage to the corresponding group of mice. The model group was given an equal amount of physiological saline by gavage,and treated continuously for 7 days. After the completion of administration,the body weight of each group of mice was recorded. The hemoglobin content of each group of mice was detected using a fully automatic cell counter,the serum iron content was detected using colorimetry,the serum ferritin content was detected using enzyme-linked immunosorbent assay (ELISA),and the spleen index was calculated. The liver tissue inflammatory factors interleukin-1β (IL-1β),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),interferon-γ (IFN-γ),interleukin-4 (IL-4),and interleukin-10 (IL-10) levels were detected using Luminex method. The mRNA expressions of liver tissue hepcidin gene (HAMP) and membrane iron transporter ( Fpn) were detected using real-time fluorescence PCR method. Results Dried tangerine peel and Chenpi absent Decoction both showed interactive effects in regulating hemoglobin,serum iron,serum ferritin content,improving spleen index,and regulating the mRNA expressions of HAMP,Fpn,as well as IL-1β and IFN-γ (P<0.05). Compared with the model group,dried tangerine peel significantly increased hemoglobin,serum iron content,and Fpn mRNA expression in ZIGI model mice,while decreasing ferritin content,spleen index,HAMP mRNA expression,and the levels of IL-1β,IL-6,TNF-α,and IFN-γ (P<0.05). Chenpi absent Decoction significantly increased serum iron content and Fpn mRNA expression in ZIGI model mice,while reducing spleen index,ferritin content,HAMP mRNA expression,and the levels of IL-1β and IFN-γ、IL-4 (P<0.05). Conclusion The effects of dried tangerine peel on inflammatory factors (IL-6 and TNF-α) and Fpn may play a key role in the improvement effects of Yigong Powder on ACD and iron metabolism.

Objective:To investigate the current situation of activity of daily living (ADL) among the community elders in Mianyang City in Sichuan Province and analyze its influencing factors, so as to provide reference for improving the ADL of the community elders.Methods:Using the convenient sampling method, from April 2020 to December 2021, a total of 17 259 community elders (≥65 years old) in 3 counties/districts in Mianyang City in Sichuan Province were selected as the research objects, and The Elderly Ability Assessment Standard Table was used to investigate them. A total of 17 259 questionnaires were sent out in this study and 16 482 were effectively received, with the effective recovery of 95.50%.Results:Among the 16 482 community elderly, a total of 20.59% (3 394/16 482) had ADL impairment, including 2 557 (75.34%) with mild ADL impairment, 517 (15.23%) with moderate ADL impairment and 320 (9.43%) with severe ADL impairment. The results of binomial Logistic regression analysis showed that age, educational level, marital status, children's status, mental state and social participation ability, perception and communication ability were the influencing factors of ADL among the elderly in community ( P<0.05) . Conclusions:The ADL impairment rate of the elderly in the community in Mianyang City is relatively high. Community medical staff should focus on the elderly. For those with low educational level, no spouse, children, impaired mental state and social participation ability and impaired perception and communication ability, the community medical staff give targeted interventions as soon as possible to improve the abilities of daily living of the elderly in the community.

Genome sequences of 4 644 representative strains from human gut microbiota were analyzed to mine gene clusters for biosynthesis of novel secondary metabolites, as well as genes encoding antibiotic resistance and virulence factors. AntiSMASH analysis showed that more than 60% of the representative strains encoded at least one secondary metabolite gene cluster, and 8 potential novel secondary metabolite gene clusters were identified from 8 unculturable bacteria. The secondary metabolite gene clusters in human intestine are mainly composed of nonribosomal peptide synthetase (NRPS), bacteriocin, arylpolyene, terpene, betalactone and NRPS like gene clusters distributed in Clostridia, Bacilli, Gammaproteobacteria, Bacteroidia, Actinobacteria and Negativicutes. PathoFact analysis showed that genes encoding antibiotic resistance and virulence factors are widely distributed in representative strains, but the frequency encoded by potential pathogens is significantly higher than that of non-potential pathogens. The frequency of genes encoding secretory toxins such as outer membrane protein, PapC N-terminal domain, PapC C-terminal domain, peptidase M16 inactive domain, and non-secretory toxins such as nitroreductase family, AcrB/AcrD/AcrF family, PLD-like domain, Cupin domain, putative hemolysin, S24-like peptidase, phosphotransferase enzyme family, endonuclease/ exonuclease/ phosphatase family, glyoxalase/ bleomycin resistance was high in potential pathogens. This study may facilitate mining new microbial natural products from the intestinal microbiome, understanding the colonization and infection mechanism of intestinal microorganisms, and providing targeted prevention and treatment of intestinal microbial related diseases.
