OBJECTIVE To establish the fingerprint of Bushen ningshen ointment， determine the contents of its major constituents， and investigate its in vitro antioxidant activity. METHODS High performance liquid chromatography （HPLC） fingerprints of 10 batches of Bushen ningshen ointment were established. Similarity evaluation and identification of common peaks were subsequently performed. The contents of 10 components such as salidroside were determined using the same HPLC method. Using the scavenging rates against 2，2′-azino bis（3-ethylbenzothiazoline-6-sulfonic acid） （ABTS） and 1，1-diphenyl-2- picrylhydrazyl （DPPH） radicals， as well as ferric ion reducing antioxidant power （FRAP） as indicators， the anti-oxidant activity of the ointment was evaluated； grey relational analysis and partial least squares regression were conducted using SIMCA 14.1 software to establish the spectrum-effect relationship. RESULTS The fingerprint chromatogram of 10 batches of Bushen ningshen ointment contained 24 common peaks， with similarity values all exceeding 0.96. Eleven peaks were identified as adenosine （peak 1）， salidroside （peak 4）， morroniside （peak 6）， catechin （peak 7）， paeoniflorin （peak 10）， spinosin （peak 11）， ferulic acid （peak 12）， isoquercitrin （peak 13）， E-mail：wli1743@163.com verbascoside （peak 14）， paeonol （peak 23）， and emodin （peak 24）. Content determination results showed that the average contents of salidroside， morroniside， catechin， paeoniflorin， spinosin， ferulic acid， isoquercitrin， verbascoside， paeonol， and emodin were 0.725， 1.962， 0.214， 3.395， 0.124， 0.107， 0.286， 0.019， 0.034 and 0.067 mg/g， respectively. The antioxidant potency composite index （APC） for the 10 batches ranged from 85.08% to 96.35%. Spectrum-effect relationship analysis indicated that all 24 common peaks were positively correlated with the antioxidant capacity. Seventeen peaks had variable importance in projection values ＞1， specitically peaks 2， 5， 6， 7， 9， 10， 13- 21， 23， and 24. CONCLUSIONS This study successfully established the HPLC fingerprint and content determination method for Bushen ningshen ointment. The compounds represented by the 17 common peaks such as morroniside may be the active components contributing to its antioxidant effects.

OBJECTIVE: To evaluate the effectiveness of correcting post-traumatic equinovarus deformity using Ilizarov external fixation technique combined with limited osteotomy. METHODS: A retrospective analysis was conducted on clinical data from 29 patients with post-traumatic equinovarus deformity treated between July 2018 and March 2023. The cohort included 18 males and 11 females, with ages ranging from 15 to 57 years (mean, 24.3 years). All patients exhibited ankylosed ankle joints with equinovarus deformity. During surgery, external fixators were installed according to Ilizarov pinning principles, and minimally invasive osteotomy was performed at the ankle joint. Concurrently, soft tissue release was achieved via minimally invasive Achilles tendon lengthening. Postoperatively, multiplanar deformity correction was accomplished through gradual adjustment of the external fixator. The fixator was removed after bony union at the osteotomy site, followed by bracing. The surgical duration, intraoperative blood loss, fixator wear time, and complications were recorded. Postoperative outcomes included assessment of deformity correction and bony union at the osteotomy site. Functional improvement and pain relief were evaluated using pre- and post-operative scores from the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) score. RESULTS: All 29 patients were followed up 12-24 months (mean, 18 months). The mean surgical duration was 85.6 minutes, with a mean intraoperative blood loss of 110 mL. Full deformity correction was achieved within 26-80 days (mean, 40.7 days) through progressive fixator adjustments. At correction completion, all ankles restored to a neutral or 5°-10° dorsiflexed position with plantigrade foot function. Superficial pin tract infections occurred in 3 patients (10.3%), resolved with local wound care, enhanced nursing, and oral antibiotics. No deep or systemic infections was observed. One patient sustained a calcaneal half-pin fracture due to a fall during fixator wear, but no bone fragment displacement occurred. No vascular or neurological complication was reported. Complete bony union was achieved at all osteotomy sites without nonunion. At last follow-up, the AOFAS ankle-hindfoot score improved from preoperative 42.7±8.7 to postoperative 65.7±9.3, and the VAS score decreased from preoperative 4.5±1.3 to postoperative 2.5±1.1, with significant differences ( P<0.05). Functional outcomes were rated as excellent in 14 cases, good in 13 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 93.1%. CONCLUSION The progressive correction strategy combining Ilizarov external fixation technique with limited foot osteotomy effectively corrects post-traumatic equinovarus deformity while preserving soft tissue integrity. This method is associated with minimal, largely controllable complications and achieves alignment stability and fusion outcomes comparable to traditional open surgery, making it an effective treatment for complex foot and ankle deformities.

Objective:To explore the clinical value of serum intestinal fatty acid-binding protein (I-FABP) for the formation and development of portal vein thrombosis (PVT) in patients with chronic hepatitis B (CHB) cirrhosis complicated with esophageal varices (EV).Methods:A retrospective analysis was performed for the clinical data of patients with CHB cirrhosis complicated with EV who were admitted to the Affiliated Hospital of Yanbian University from September 2020 to October 2023 in this cohort study. PVT was diagnosed and graded according to the imaging examination, and patients were divided into PVT group and non-PVT group. The thrombus recanalization of PVT in PVT group and newly occurring PVT events in non-PVT group was observed during twelve-month follow-up. Enzyme linked immunosorbent assay was used to measure the baseline level of I-FABP. Mann-Whitney U test was used for comparison between two groups. Kaplan-Meier curves and receiver operator characteristic (ROC) curves were used to evaluated the predictive performance of I-FABP for newly occurring PVT event. The cumulative incidence was compared by log-rank test. Results:A total of 161 patients with CHB cirrhosis complicated with EV were included, with an average age of (57.71±11.12) years old, including 46 patients with PVT and 115 patients without PVT. During the follow-up period, 11 PVT patients had thrombus recanalization. Meanwhile, 17 patients without PVT had newly occurring PVT events. The I-FABP level was 2.59 (1.63, 3.18) μmol/L in the PVT group and 1.94 (1.44, 2.81) μmol/L in the non-PVT group, and the difference was statistically significant ( Z=2.12, P=0.034). The baseline I-FABP level in patients with newly occurring PVT event was higher than that in patients without PVT (2.78(1.86, 3.20) μmol/L vs 1.92 (1.18, 2.74) μmol/L), while the I-FABP level in patients with thrombus recanalization was lower than that in patients without thrombus recanalization (2.06 (1.16, 2.69) μmol/L vs 2.84 (1.92, 3.27) μmol/L). The differences were both statistically significant ( Z=2.61 and 2.25, respectively, both P<0.05). The non-PVT patients were stratified according to the median level of I-FABP, and the Kaplan-Meier curve showed that patients with I-FABP<1.94 μmol/L in the non-PVT group had a significantly lower cumulative rate of newly occurring PVT during follow-up compared to those with I-FABP≥1.94 μmol/L (7.1% (4/56) vs 22.0% (13/59), χ2=5.03, P=0.025). The ROC curve showed that I-FABP had a certain predictive efficacy for the occurrence PVT. The area under the curve were 0.698 (95% confidence interval 0.606 to 0.780) and the optimal cut-off of 2.36 μmol/L, with sensitivity of 70.59% and specificity of 69.39%. Conclusion:I-FABP is not only associated with PVT recanalization in CHB cirrhosis, but also a potential biomarker for predicting PVT formation and development.

The adipose tissue of mammals represents an important energy-storing and endocrine organ, and its dysfunction is relevant to the onset of several health problems, including non-alcoholic fatty liver disease (NAFLD). However, whether treatments targeting adipose dysfunction could alleviate NAFLD has not been well-studied. Adrenomedullin 2 (ADM2), belonging to the CGRP superfamily, is a protective peptide that has been shown to inhibit adipose dysfunction. To investigate the adipose tissue-specific effects of ADM2 on NAFLD, adipose-specific ADM2-overexpressing transgenic (aADM2-tg) mice were developed. When fed a high-fat diet, aADM2-tg mice displayed decreased hepatic triglyceride accumulation compared to wild-type mice, which was attributable to the inhibition of hepatic de novo lipogenesis. Results from lipidomics studies showed that ADM2 decreased ceramide levels in adipocytes through the upregulation of ACER2, which catalyzes ceramide catabolism. Mechanically, activation of adipocyte HIF2α was required for ADM2 to promote ACER2-dependent adipose ceramide catabolism as well as to decrease hepatic lipid accumulation. This study highlights the role of ADM2 and adipose-derived ceramide in NAFLD and suggests that its therapeutic targeting could alleviate disease symptoms.

Objective:To explore the clinical efficacy of free superficial circumflex iliac artery perforator flap (SCIAPF) in reconstruction of soft tissue defects of hand and foot in children.Methods:From August 2021 to August 2023, free SCIAPFs were used to reconstruct soft tissue defects of hands and feet in 8 children at the Department of Hand and Foot Surgery, Zhoukou Huaihai Hospital. There were 6 boys and 2 girls aged between 2 and 7 years old. The sites of soft tissue defect were: 1 of metacarpophalangeal joint in the functional area of left thumb, 2 of dorsal right hand, 1 of dorsal left foot, 2 of medial malleolus of right foot, and 2 of right forefoot, and all were accompanied with tendon and bone exposure. The size of soft tissue defects ranged from 2.5 cm×3.0 cm to 6.0 cm×3.5 cm. After emergency debridement, the children received flap transfers, the flaps sized from 3.0 cm×3.5 cm to 7.0 cm×4.0 cm. Donor sites were closed by running intradermal suture. All children were included in the scheduled postoperative follow-up by visit of outpatient clinic, WeChat interviews and home visits to observe the appearance, colour, texture and sensation of the flaps, the functional recovery of the affected hands and feet, as well as the healing of donor sites.Results:After surgery, all 8 flaps survived beside 1 had a partial necrosis at the edge and healed with a scab after dressing change. Flap donor sites healed in one stage. Scheduled postoperative follow-up lasted from 7 to 22 months, with an average of 10 months. The flaps presented a slightly bloated appearance, soft texture with a restored protective sensation and satisfactory functional recovery of hands and feet. Linear scars were left at the donor sites. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 1 child was of excellent and 2 children of good in hand function of the 3 children with hand injury. The Maryland Foot Score revealed 3 children were of excellent and 2 of good in foot function of the 5 children with foot injury.Conclusion:Free SCIAPF is an ideal option for reconstruction of soft tissue defects of hand and foot in children, with concealed donor site, convenient flap harvesting, fewer complications and satisfactory reconstructive effect.
