OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of deucravacitinib in the treatment of moderate- to-severe plaque psoriasis. METHODS Rapid health technology assessment (HTA) reports, systematic reviews (SR)/meta- analyses, and pharmacoeconomic studies on deucravacitinib for the treatment of moderate-to-severe plaque psoriasis were identified by searching PubMed, Web of Science, Embase, CNKI, Wanfang data and official HTA websites. The search time frame spanned from database inception to July 2025. After literature screening, data extraction, and quality assessment, the study results were subjected to descriptive analysis and synthesis. RESULTS A total of 14 articles were finally included, consisting of 1 HTA report, 10 SR/meta-analyses, and 3 pharmacoeconomic studies. Regarding efficacy, deucravacitinib demonstrated superior efficacy to both placebo and apremilast, with significantly higher response rates for Psoriasis Area and Severity Index 50/75/90/100, Static Physician’ s Global Assessment 0/1, and Dermatology Life Quality Index 0/1, as well as greater reduction in Psoriasis Symptoms and Signs Diary Score (P<0.05). Regarding safety, deucravacitinib was well-tolerated. Although the overall incidence of adverse events (AEs) was higher than placebo, it was not significantly different from apremilast. Moreover, the incidence of serious AEs and the rate of discontinuation due to AEs did not differ significantly from placebo (P>0.05). Regarding cost-effectiveness, deucravacitinib proved to be more cost-effective than apremilast across multiple healthcare system perspectives, including those of the United States, Japan, and China. CONCLUSIONS Deucravacitinib exhibits favorable efficacy, safety, and cost-effectiveness in the treatment of moderate-to-severe plaque psoriasis. Additional real-world studies are warranted to further refine its evaluation.

ObjectiveTo evaluate the clinical effectiveness and safety of Modified Zhigancao Granules (炙甘草汤加味颗粒) for preventing the early recurrence following radiofrequency ablation in patients with atrial fibrillation (AF) of qi-yin deficiency syndrome. MethodsA multi-center, randomized, double-blind, placebo-controlled trial was designed. A total of 116 patients with atrial fibrillation of qi-yin deficiency syndrome who underwent radiofrequency ablation for the first time were enrolled from 3 centers, and they were randomly divided into a treatment group (59 cases) and a control group (57 cases). Both groups received basic western medicine treatment after surgery. In addition, the treatment group was given oral Modified Zhigancao Granules, while the control group was given oral placebo granules. The dosage for both groups was 20 g each time, twice a day, with continuous treatment for 12 weeks. The recurrence of atrial fibrillation in both groups was recorded at 24 hours, 4 weeks, 8 weeks, and 12 weeks after surgery. The serum levels of B-type natriuretic peptide (BNP), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor-α (TNF-α) were detected before treatment and 12 weeks after treatment in both groups. The scores of Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) Questionnaire (including scores of the daily life dimension, symptom dimension, treatment worry dimension, treatment satisfaction dimension, and total score) and traditional Chinese medicine (TCM) syndrome scores were compared before treatment and at 4 weeks, 8 weeks, and 12 weeks between groups. Safety indicators such as blood routine, urine routine, liver function, and renal function were monitored before and after treatment. ResultsNine of the treatment group and seven of the control group dropped out. Finally, 50 patients in each group were included in the statistical analysis. At 24 hours, 4 weeks, 8 weeks, and 12 weeks after surgery, the recurrence rates of AF in the treatment group were 2.0% (1/50), 2.0% (1/50), 4.0% (2/50), and 10.0% (5/50), respectively; while those in the control group were 2.0% (1/50), 26.0% (13/50), 28.0% (14/50), and 34.0% (17/50), respectively. Compared with the control group at the same time points, the early recurrence rates of AF in the treatment group were significantly lower at 4 weeks, 8 weeks, and 12 weeks after surgery (P<0.01). Compared with the baseline within group, BNP, hs-CRP, IL-6, and TNF-α in the treatment group all decreased after 12 weeks of treatment (P<0.05); the difference in hs-CRP levels (before vs. after treatment) in the treatment group was higher than that in the control group (P<0.01). Compared with the baseline within group, both groups showed decreases in the total score of AFEQT Questionnaire, scores of the daily life dimension, treatment worry dimension, symptom dimension, and TCM syndrome scores at 4 weeks, 8 weeks, and 12 weeks after treatment. Meanwhile, the score of the treatment satisfaction dimension of AFEQT increased in both groups (P<0.01), and the improvements in all the above scores in the treatment group were superior to those in the control group at all time points (P<0.05 or P<0.01). All safety indicators of patients in both groups were within the normal range before treatment and at 12 weeks after treatment, and no adverse reactions or adverse events occurred in either group. ConclusionModified Zhigancao Granules can reduce the early recurrence rate following radiofrequency ablation in AF patients with qi-yin deficiency syndrome, improve clinical symptoms and quality of life, suppress inflammatory response, and show good safety.

ObjectiveTo investigate the effects and potential mechanisms of Tongmai Yangxin Pills (通脉养心丸) (TYPs) in preventing ischemia-reperfusion (I/R)-induced arrhythmia. MethodsSixty male SD rats were randomly assigned to sham operation group, model group, amiodarone group, low-dose and high-dose TYPs group, with 12 rats in each group. The sham operation group and the model group received 10 g/(kg·d) normal saline by gavage, the amiodarone group received 60 mg/(kg·d) amiodarone, and the low-dose and high-dose TMP groups received 1 g/(kg·d) and 2 g/(kg·d) TYPs solution respectively, for 21 days, administered twice daily. On the day after the last administration, the I/R model was established in the model and medication groups by ligation of the left anterior descending coronary artery with a cannula, while the sham operation group underwent the same procedure without ligation. Electrocardiogram recordings were continuously monitored throughout the modeling process. Heart rate was recorded at five time points, before ischemia (t-0), 5-10 min after ischemia (t-1), 10-15 min after ischemia (t-2), 15-30 min after ischemia (t-3), and during the first 2 min of reperfusion (t-4); the incidence of arrhythmia including ventricular premature beats (VPB), ventricular tachycardia (VT), and ventricular fibrillation (VF) was recorded; arrhythmia scores were calculated. After 24 hours of reperfusion, left ventricular myocardial tissue was collected. Hematoxylin-eosin (HE) staining was performed to observe pathological changes. RT-PCR was used to detect the mRNA expression of microRNA-1 (miRNA-1), microRNA-133a (miRNA-133a), and potassium (K+) and calcium (Ca2+) ion channel-related genes including KCND2, KCNH2, KCNE2, KCNQ1, KCNE1, KCNJ2, CACNA1C, and CACNB1. Western blot analysis was used to measure protein levels of transient outward potassium current protein (Kv4.2), rapidly activating delayed rectifier potassium current protein (HERG), slowly activating delayed rectifier potassium current protein (KvLQT1), inward rectifier potassium current protein (Kir2.1), and L-type calcium channel protein (Cav1.2). ResultsCompared with sham operation group, the model group showed diffuse myocardial hemorrhage, inflammatory cell infiltration, myocardial necrosis, nuclear pyknosis, vacuolar degeneration, and disrupted myocardial fibers; the model group also exhibited a decreased heart rate (t-1 to t-4), increased arrhythmia scores, elevated miRNA-1 and miRNA-133a expression, and decreased mRNA expression of KCND2, KCNH2, KCNE2, KCNQ1, KCNE1, KCNJ2, CACNA1C, and CACNB1 in myocardial tissue; additionally, Kv4.2, HERG, KvLQT1, Kir2.1, and Cav1.2 protein levels significantly reduced (P<0.01). Compared to the model group, all medication-treated groups showed reduced myocardial damage, including less hemorrhage, reduced inflammatory infiltration, and improved myocardial structure, with the high-dose TYPs group exhibiting the most significant improvement; the amiodarone group and high-dose TYPs group showed a significant increase in heart rate (t-1 to t-4), lower arrhythmia scores, reduced miRNA-1 and miRNA-133a expression; the high-dose TYPs group exhibited significantly increased mRNA expression levels of KCND2, KCNH2, KCNQ1, KCNJ2, and CACNA1C, as well as elevated protein levels of Kv4.2, HERG, KvLQT1, Kir2.1, and Cav1.2 (P<0.05 or P<0.01). ConclusionTMPs can improve myocardial damage and reduce the incidence of ventricular arrhythmia in I/R rats. The underlying mechanism may be related to the downregulation of miRNA-1 and miRNA-133a gene expression, as well as the upregulation of K+ and Ca2+ channel-related genes and proteins.

OBJECTIVE:
To explore the effectiveness and feasibility of two osteotomy guides in medial open wedge high tibial osteotomy (MOWHTO).
METHODS:
Clinical data of 103 patients who underwent routine MOWHTO surgery between January 2020 and December 2022 were collected for retrospective analysis. The patients were divided into two groups based on the method of osteotomy guide plate. The control group of 51 patients received traditional osteotomy guide plate technique, including 17 males and 34 females, aged from 48 to 68 years old with an average of(57.93±4.82) years old, with a disease duration ranged from 1 to 8 years with an average of (4.89±1.49) years. The observation group of 52 patients received personalized osteotomy guide plate technique, including 23 males and 29 females, aged from 48 to 69 with an average of (58.22±5.10) years, with a disease duration ranged from 1 to 9 years with an average of(5.10±1.55) years. The perioperative indicators, complications, and knee joint recovery rate were statistically analyzed for both groups, as well as the preoperative and postoperative coagulation function, fibrinogen (FIB), D-dimer (D-D), gait parameters (step frequency, step length, step speed), biomechanical indicators, weight bearing line (WBL), medial proximal tibial angle (MPTA), joint line conergence angle (JLCA), and anterior cruciate ligament (ACL) function (body width, tibial anterior displacement).
RESULTS:
All patients were followed up for 6 months. The intraoperative blood loss, operation time, and number of fluoroscopic views in the observation group were (358.58±93.76) ml, (84.42±8.17) min, and (2.00±0.44) times, respectively, which were all less than those in the control group (465.55±105.38) ml, (96.53±10.51) min, and (6.31±0.58) times (P<0.05). Three days after surgery, the FIB and D-D levels in the observation group were (4.21±0.48) g·L-1 and (204.47±35.59) μg·L-1, respectively, which were both lower than those in the control group (5.56±0.57) g·L-1 and (311.12±42.23) μg·L-1 (P<0.05). Three months after surgery, the step frequency, step length, and step speed in the observation group were (1.89±0.23) steps·s-1, (0.57±0.15) m, and (0.99±0.11) m·s-1, respectively, which were all higher than those in the control group (1.80±0.18) steps·s-1, (0.50±0.14) m, and (0.95±0.09) m·s-1 (P<0.05). Three months after surgery, the WBL and MPTA in the observation group were (45.53±4.41)% and (87.03±8.15)°, respectively, which were both higher than those in the control group (38.38±4.36)% and (83.68±8.50)°, and the JLCA was (2.36±0.24)°, which was lower than that in the control group (2.61±0.33)° (P<0.05). The ACL body width during internal fixation removal was (5.60±0.51) mm, which was greater than that in the control group (5.08±0.56) mm, and the tibial migration was (5.70±0.42) mm, which was less than that in the control group (6.33±0.48) mm (P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Six months after surgery, there was no significant difference in the recovery rate of knee joint between the two groups (P>0.05).
CONCLUSION
The application of personalized osteotomy guide technique in MOWHTO can help improve knee biomechanics and ACL function, and has less effect on coagulation function and no increase in complications.
