OBJECTIVE To compare the efficacy and safety of tildrakizumab versus secukinumab in the treatment of moderate-to-severe plaque psoriasis. METHODS A retrospective analysis was conducted on 141 patients with moderate-to-severe plaque psoriasis treated at the First Affiliated Hospital of Nanyang Medical College from January 2024 to April 2025. According to the treatment regimen，the patients were divided into tildrakizumab g roup （ n ＝61） and secukinumab group （ n ＝80）. The PASI 75，PASI 90，and PASI 100 response rates， the Psoriasis Area and Severity Index （PASI） and Dermatology Life Quality Index （DLQI） scores， skin barrier function （sebum content and stratum corneum water content）， inflammatory factor levels [interleukin-17 （IL-17）， tumor necrosis factor-α （TNF-α）， and IL-23 ] before and after treatment， and the incidence of adverse drug reactions during treatment were compared between the two groups. RESULTS After 12 weeks of treatment， the PASI 75， PASI 90， and PASI 100 response rates in the tildrakizumab group were significantly higher than those in the secukinumab group （ P ＜0.05）. After treatment， PASI and DLQI scores as well as serum levels of IL-17， TNF-α， and IL-23 in both groups were significantly reduced compared to before treatment in the same group； sebum content and stratum corneum water content were significantly increased compared to before treatment in the same group （ P ＜0.05）； the tildrakizumab group showed better results than the secukinumab group （ P ＜0.05）. The overall incidence of adverse drug reactions was also significantly lower in the tildrakizumab group compared with the secukinumab group （ P ＜0.05）. CONCLUSIONS Compared with secukinumab， tildrakizumab demonstrates superior efficacy in the treatment of moderate-to-severe plaque psoriasis， providing improved symptom relief， enhanced skin barrier function， reduced levels of inflammatory factors， and higher safety.

ObjectiveTo observe the effect of heat-sensitive moxibustion on quality of life and immune function in non-small cell lung cancer （NSCLC） patients undergoing chemotherapy. MethodsSeventy NSCLC patients with qi deficiency and phlegm stasis syndrome were randomly divided into an intervention group and a control group， with 35 cases in each group. The control group received chemotherapy combined with routine symptomatic treatment， while the intervention group additionally received heat-sensitive moxibustion since the first day of chemotherapy. Acupoints included Dazhui （GV14）， bilateral Feishu （BL13）， Zhongwan （CV12）， Qihai （CV6）， and Guanyuan （CV4）. The site exhibiting the strongest heat-sensitization response was selected for moxibustion. Treatment was administered for 45 minutes per session， three times weekly for three consecutive weeks， totaling nine sessions. Before and after treatment， quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire （EORTC QLQ-C30）， and traditional Chinese medicine （TCM） syndrome scores were evaluated. Peripheral blood levels of natural killer （NK） cells and T-lymphocyte subsets including CD3⁺， CD4⁺， and CD8⁺， and CD4⁺/CD8⁺ ratio were measured. Levels of programmed cell death protein-1 （PD-1）， including PD-1⁺CD4⁺ and PD-1⁺CD8⁺ cells， were also assessed. Liver and renal function were monitored before and after treatment， and adverse events were recorded. ResultsIn the intervention group， 1 participant withdrew and 1 was excluded， while in the control group， 2 participants withdrew. Ultimately， 33 participants in each group were included in the final analysis. The intervention group showed significant improvements in physical， role， emotional， cognitive， and social functioning， as well as global health status after treatment， while scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and TCM syndrome scale were significantly decreased （P＜0.05）. Moreover， the intervention group demonstrated higher scores in physical functioning， role functioning， and global health status， as well as lower scores for fatigue， nausea and vomiting， dyspnea， appetite loss， diarrhea， and the TCM syndrome scale than the control group （P＜0.05）. After treatment， the levels of peripheral NK cells and PD-1⁺CD8⁺ T cells in the intervention group increased significantly； furthermore， the intervention group exhibited higher peripheral NK cell levels and lower PD-1⁺CD8⁺ T cell levels than the control group （P＜0.05）. No significant differences were found in liver or renal function between the two groups （P＞0.05）. In addition， no adverse events such as burns or moxibustion-induced syncope occurred during the study. ConclusionHeat-sensitive moxibustion as an adjunctive therapy may enhance immune function， alleviate clinical symptoms， and improve quality of life， while demonstrating a favorable safety profile in NSCLC patients with qi deficiency and phlegm stasis.

[Objective] To investigate the infection status and characteristics of HEV among voluntary blood donors in Ningbo, and to provide a basis for improving the blood screening strategy. [Methods] A total of 12 227 blood samples from voluntary blood donors in Ningbo from June 2022 to May 2023 were tested for HEV serology, enzymology, and nucleic acid testing. Furthermore, HEV gene sequencing was performed for genotyping analysis, and donors with reactive nucleic acid testing results were followed up to confirm their infection status. [Results] The reactivity rate of HEV Ag, anti-HEV IgM and anti-HEV IgG was 0.098%, 0.899% and 29.198%, respectively. There was no difference in the reactivity of anti-HEV IgM and anti-HEV IgG between genders, donation frequencies and donation types (P>0.05). The reactivity rate increased significantly with age (P<0.05). The rate of ALT disqualification (ALT>50U/L) was significantly higher than that in non-reactive samples (P<0.05). The HEV Ag reactivity rate (0.098%) was not correlated with gender, donation frequency, donation type or age. One HEV RNA positive case was found, with a positive rate of 0.008%(1/12 227). It was confirmed to be hepatitis E virus genotype 3 by sequencing analysis. Apart from HEV Ag reactivity, all other blood safety screening items were non-reactive, suggesting this case might be in the acute infection phase. The follow-up results showed that all indicators of the donor's previous blood donation were non-reactive. [Conclusion] Pre-donation ALT detection can reduce the risk of transfusion-transmitted HEV (TT-HEV) to a certain extent, and the effective way to prevent TT-HEV is to detect HEV RNA and serology of donor blood.

Objective To analyze the status quo of exercise compliance in patients with chronic heart failure and its influencing factors.Methods Using convenient sampling method,425 patients with chronic heart failure in General Hospital of Ningxia Medical University from August 2022 to February 2023 were se-lected as the study objects.General data questionnaire,exercise compliance scale,exercise self-efficacy scale,heart-activity fear tampa scale,Pittsburgh sleep quality index,perceptive social support scale and psychological experience scale were used to investigate and analyze the results.Results 415 effective questionnaires were collected,with a recovery rate of 97.65%.The total score of exercise compliance in patients with chronic heart failure was 88.94±17.12.The results of multiple linear regression analysis showed that BMI,hospitalization times and fear of cardiac activity negatively affected patients'exercise compliance,while education level,exer-cise self-efficacy,perceptive social support and retirement positively affected patients'exercise compliance(P＜0.05).Conclusion The overall level of exercise compliance of patients with chronic heart failure is poor,and timely intervention measures should be taken.

Objective To explore the mechanism by which electroacupuncture improves ocular surface inflammation in dry eye mice.Methods 30 SPF-grade healthy male ICR mice were randomly divided into a blank group,a model group,a sham electroacupuncture group,a western medicine group and an electroacupuncture group,with 6 mice in each group.Mice in the blank group and other four groups were subcutaneously injected 200 μL of sterile physiological saline and 200 μL of scopolamine hydrobromide(0.5 mg dissolved in 0.2 mL of sterile physiological saline)at 8:00,11:00,14:00,and 17:00 every day for 35 consecutive days,respectively.From the 22nd day,mice in the sham electroacupunc-ture group were given blunt scalp acupuncture intervention at bilateral Jingming and Taiyang points,without subcutaneous penetration.In the western medicine group,fluorometholone eye drops were applied to both eyes of the mice at 8:00,13:00,and 18:00 daily,with 1 drop each time.Mice in the electroacupuncture group were given electroacupuncture in-tervention,with the same acupoint location and acupuncture time as the sham electroacupuncture group.The electroacu-puncture frequency was 2 Hz/20 Hz,the waves were sparse-dense and the intensity was 1 mA,once a day for 15 min.All groups were intervened for 14 days.The corneal fluorescein(FL)staining scores of mice in each group were detected be-fore modeling,after modeling,and after intervention.The corneal tissue morphology was observed under a light micro-scope.Immunohistochemistry staining and quantitative reverse transcription polymerase chain reaction(qRT-PCR)were used to detect the protein and mRNA expression of high mobility group box 1(HMGB1)and receptor for advanced glyca-tion end products(RAGE)in the cornea,respectively.Results The FL scores of mice in model,sham electroacupunc-ture,western medicine,and electroacupuncture groups all significantly increased after modeling and intervention,com-pared with those before modeling(all P＜0.01).The FL scores of mice in electroacupuncture and western medicine groups significantly decreased after intervention,compared with those after modeling(both P＜0.01).Compared with the model group,electroacupuncture and western medicine groups showed a significant drop in FL score after intervention(both P＜0.01).HE staining showed that after intervention,mice in electroacupuncture and western medicine groups had a basically normal number of corneal epithelial layers,no obvious shedding of epithelial cells,and neatly arranged and slightly swollen collagen fibers in the stromal layer.The relative protein expression levels of HMGB1 and RAGE in the corneal tissue of both model and sham electroacupuncture groups were significantly higher than those of the blank group(allP＜0.01).The rela-tive protein expression levels of HMGB1 and RAGE in the corneal tissue of both electroacupuncture and western medicine groups were significantly lower than those of the model group(all P＜0.01).The relative mRNA expression levels of HMGB1 and RAGE in the corneal tissue of both model and sham electroacupuncture groups were significantly higher than those of the blank group(all P＜0.01).The relative mRNA expression levels of HMGB1 and RAGE in the corneal tissue of both electroacupuncture and western medicine groups were significantly lower than those of the model group(all P＜0.01).Conclusion Electroacupuncture mitigates corneal epithelial injury,reduces the expression of HMGB1 in the cor-neal tissue,inhibits the binding of HMGB1 and RAGE,and ultimately alleviates ocular surface inflammation responses of dry eye mice.

Objective:To evaluate the efficacy of ultrasound-guided median interspinous in-plane approach to subarachnoid puncture in obese pregnant patients.Methods:This study was a randomized controlled trial. Eighty obese parturients who underwent elective cesarean section from March 2022 to January 2024 in our hospital were divided into 2 groups( n=40 each) by the random number table method: median interspinous in-plane approach group(group M) and paramedian interlaminar in-plane approach group(group P). After successful puncture, 0.5% ropivacaine 15 mg(3 ml) was intrathecally injected in both groups. The first-attempt success of puncture, the number of puncture attempts, operation time, the total success of puncture, and the visibility scores of the anterior and posterior union, positioning structure(lamina in group P, spinous process in group M) and puncture needle under ultrasound were recorded. Results:Compared with group P, the visibility score of positioning structure under ultrasound was significantly increased, the success rate of puncture at the first attempt was increased, the number of puncture attempts was decreased, the operation time was shortened, the total success rate of puncture was increased( P<0.05), and no significant change was found in the visibility scores of the anterior and posterior union and puncture needle in group M( P>0.05). Conclusions:For obese pregnant patients, the ultrasound-guided median interspinous in-plane approach can accurately and quickly perform subarachnoid puncture, which has more advantages than the traditional paramedian interlaminar in-plane approach.

Objective:To investigate the clinical manifestations, therapeutic strategies and prognostic outcomes in pediatric patients with severe Mycoplasma pneumoniae pneumonia (SMPP) complicated by cardiac thrombosis. Methods:This case series study retrospectively analyzed 15 pediatric patients with SMPP complicated by cardiac thrombosis. The patients was recruited from the Department of Pediatric Respiratory Medicine at Shandong Provincial Hospital Affiliated to Shandong First Medical University between July 2018 and January 2025. Comprehensive clinical data and follow-up information were collected.Results:Among the 15 children, 10 were male and 5 were female, and the age of onset was 8.0 (6.3, 10.0) years. All 15 children presented with fever and cough, while additional symptoms included dyspnea in 7 cases, chest pain in 6 cases, hemoptysis in 3 cases, and chest tightness in 1 case. The white blood cell count was 11.7 (9.5, 15.9)×10 9/L, C-reactive protein was 31.6 (17.5, 64.8) mg/L and lactate dehydrogenase was 548.2 (410.4, 768.3) U/L. A total of 14 children underwent testing for the Mycoplasma pneumoniae drug resistance genes 2063A>G and 2064A>G, of which 13 tested positive. The plasma D-dimer levels of 15 children were 8.77 (7.23, 12.50) mg/L, all of which were higher than normal. Among the 15 children, 5 had decreased activity of anticoagulant proteins (protein C, protein S, antithrombin Ⅲ), and 8 tested positive for antiphospholipid antibodies. Chest CT scans of all 15 children showed pulmonary consolidation and (or) atelectasis, with pleural effusion present in 12 cases. In the 15 children, thrombosis was detected at 14.0 (11.0, 18.0) days after the onset of illness. The locations of cardiac thrombosis included the right ventricle in 9 cases, the right atrium in 5 cases, and the left atrium in 1 case. Additionally, 10 cases had pulmonary vascular embolism, comprising 9 cases of pulmonary artery thrombosis and 1 case of pulmonary vein thrombosis. After anticoagulant treatment, cardiac thrombi disappeared in 10 children. Five children who did not show improvement with anticoagulation underwent surgical thrombectomy. In the follow-up of 15 children, lung imaging basically returned to normal, with no major hemorrhagic events or other adverse events. Conclusions:In children with Mycoplasma pneumoniae pneumonia, the presence of clinical symptoms such as shortness of breath, chest pain and hemoptysis, along with elevated plasma D-dimer levels, should raise suspicion for the possibility of cardiac thrombosis. SMPP complicated by cardiac thrombosis, prognosis is good following anticoagulation or surgical treatment.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.
