Objective: To systematically evaluate the clinical efficacy of topical preparations of Mongolian medicine Manggari hot compress therapy (hereafter referred to as Manggari hot compress therapy) in treating cervical spondylotic radiculopathy (CSR) and explore the possible pharmacological material basis in the formula, providing evidence for the clinical application of Mongolian medicine in the treatment of CSR. Methods: The clinical trial employed a randomized, controlled, open-label, and outcome-assessor-blinded design. The CSR patients who were treated at the Department of Traditional Therapeutics Outpatient Clinic, Xilinguole Meng Mongolian General Hospital between July 1, 2024 and August 31, 2025, were enrolled. They were randomly assigned to three groups: an oral control group (administration of oral administration of mecobalamin tablets combined with cervical electric traction), an experimental group (Manggari external hot compress), and a patch control group (flurbiprofen gel plaster). The intervention lasted two weeks. Before and after treatment, the following subjective indicators were recorded: Mongolian Medicine Syndrome (MMS) score, Visual Analog Scale (VAS) score, Northwick Park Neck Pain Questionnaire (NPQ) score, and tongue morphology. Serum levels of inflammatory markers [tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β)] and oxidative stress markers [malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, and glutathione peroxidase (GSH-Px) activity] were measured using enzyme-linked immunosorbent assay (ELISA). Overall therapeutic efficacy was evaluated. One month after treatment completion, a follow-up assessment was conducted, and the MMS, VAS, and NPQ scores were recorded again for all patients. For the pharmacological substance exploration, ultra-high-performance liquid chromatography-Q-exactive orbitrap-mass (UHPLC-QE-MS) was employed to analyze blood-absorbed prototype components of Manggari, under both positive and negative ion modes. The targeting relationship between the core active compounds and the target protein was validated using molecular docking. Results: This study ultimately included 90 patients with CSR for analysis. Baseline characteristics showed no statistically significant differences among the three groups (P > 0.05). (i) Symptom scores. After treatment, the MMS, VAS, and NPQ scores decreased significantly from baseline in all three groups (P < 0.001). At follow-up, there was no significant difference in MMS, VAS, and NPQ scores of the experimental group compared with those at the end of the treatment (P > 0.05). After treatment, the experimental group showed significantly greater reductions in MMS, VAS, and NPQ scores than oral control and patch control groups (P < 0.001). At follow-up, these differences remained significant (P < 0.001). (ii) Inflammatory and oxidative stress markers. After treatment, serum levels of TNF-α, IL-6, and IL-1β, and MDA activity decreased significantly from baseline in all three groups (P < 0.001), and SOD content and GSH-Px activity increased significantly from baseline (P < 0.05). After treatment, the experimental group had significantly lower serum levels of TNF-α, IL-6, and IL-1β than oral and patch control groups. Additionally, it exhibited lower MDA activity and higher SOD content and GSH-Px activity compared with the two control groups. (P < 0.05). (iii) Overall efficacy. The total effective rate was 93.33% in the experimental group, 86.66% in the oral control group, and 83.33% in the patch control group. (iv) Pharmacological substance analysis. A total of 152 compounds were identified in the blood-absorbed components of Manggari. Among them, the core compounds—4-hydroxycoumarin, N-methylanthranilic acid, genistein, and ginsenoside-Rk1—showed binding energies to the key target proteins TNF-α and IL-1β range from − 4.7 to − 7.1 kcal/mol, with the majority of the binding energies being below − 5.0 kcal/mol, suggesting that it generally has a good binding affinity. Conclusion Mongolian medicine hot compress therapy effectively modulates inflammatory and oxidative stress responses through the combined action of its thermal effects and active pharmaceutical ingredients Manggari. It inhibits cervical nerve root inflammation and alleviates radicular pain, improving clinical symptoms, reducing pain severity, and alleviating neck functional disability.

Objective:To investigate the efficacy of hybrid fixation with tibial prosthesis in primary total knee arthroplasty (TKA) in patients with osteoporosis or osteopenia.Methods:A total of 39 patients (42 knees) with knee osteoarthritis who underwent primary TKA with hybrid fixation with tibial prosthesis in the First Affiliated Hospital of Zhejiang University from November 2022 to June 2024 were retrospectively analyzed. There were 12 males and 27 females with an average age of 68.23±7.02 years (range, 58-89 years). The mean body mass index was 26.15±4.63 kg/m 2 (range, 19.48-39.03 kg/m 2), and the mean bone mineral density T score was -2.38±0.78 (from -4.2 to -1.2). The left knee was 19, and the right knee was 23. The visual analogue scale (VAS) and Knee Society score (KSS) were used to evaluate the knee joint pain and function, and the knee flexion range of motion was measured. Radiographic evaluation included hip-knee-ankle angle, lateral distal femoral angle, and posterior slope of tibial plateau. Results:All patients successfully completed the operation and were followed up for 19.8±5.1 months (range, 4.9-23.6 months). All patients were treated with hybrid fixation with tibial prosthesis assisted by 3D printed porous titanium alloy sleeve. The operation time was 73.8±10.8 min (range, 54-98 min). Thirty-four of 39 patients received standard anti-osteoporosis therapy before operation. The VAS score at the last follow-up was 0(0, 1), which was lower than that before operation 7(6,8), and the difference was statistically significant ( U<0.001, Ρ<0.001). The KSS clinical score at the last follow-up was 76.67±10.04, which was higher than that before operation (50.95±7.35), and the difference was statistically significant ( t=12.030, Ρ<0.001). The knee flexion range of motion at last follow-up was 97.26°±12.94°, showing no significant difference when compared with preoperative 94.52°±16.52° ( t=0.846, Ρ=0.400). The hip-knee-ankle angle at last follow-up was 176.2°±2.54°, which was significantly higher than that before operation 173.5°±5.25° ( t=3.328, Ρ=0.002). The distal lateral femoral and posterior tibial inclination angles at the final follow-up were 89.58°±1.62° and 2.85°±0.91°, respectively, compared with 90.71°±4.01° and 3.05°±1.25° preoperatively, with no statistically significant differences ( t=1.556, Ρ=0.127; t=0.923, Ρ=0.359). No prosthesis loosening, dislocation, periprosthetic infection, deep vein thrombosis and other complications occurred. Conclusion:Hybrid fixation with tibial prosthesis in primary TKA for patients with osteoporosis or osteopenia has a satisfactory clinical effect, which can relieve knee pain and improve joint function.

Objective:To explore the early effects and safety of using a hybrid fixation strategy with 3D-printed porous tantalum metal augments to reconstruct substantial bone defects in complex primary total knee arthroplasty (TKA).Methods:A retrospective analysis was performed on the clinical data from August 2019 to September 2023, encompassing 20 patients (21 knees) with significant bone loss who underwent hybrid fixation with 3D-printed porous tantalum augments. The procedures were conducted at two medical centers: the First Affiliated Hospital, School of Medicine, Zhejiang University (11 cases) and Xiangya Hospital of Central South University (9 cases). The study cohort comprised 6 males (6 knees) and 14 females (15 knees), with a mean age of 61.05±11.23 years (range, 42-80 years). The distribution of cases was 7 on the left side and 14 on the right side. All cases were categorized as type 3 according to the Anderson Orthopaedic Research Institute (AORI) classification system. The cohort included 19 unilateral and 1 bilateral case, with 5 involving complex primary replacements (3 with Charcot arthropathy, 1 with syphilitic arthropathy, and 1 with severe valgus deformity) and 16 revision surgeries (13 for aseptic loosening and 3 for infection). Preoperative assessments included routine CT scans and digital three-dimensional reconstructions to identify large metaphyseal defects exceeding 50% of the metaphyseal area or those thicker than 10 mm. For such defects, 3D-printed standardized porous tantalum augments were implemented. In cases of extensive cavitary bone defects or severe metaphyseal defects where the medial and lateral defects collectively exceeded 80% of the metaphyseal region or where the residual bone stock was insufficient for screw fixation of standardized augments, 3D-printed personalized custom-made porous tantalum augments were employed for hybrid fixation and repair. Comparative analyses were conducted on pre- and postoperative imaging data (prosthesis positioning and complications), knee range of motion (ROM), visual analogue scale (VAS) for pain, and Knee Society score (KSS).Results:Of the cases, 17 were repaired using standardized 3D-printed porous tantalum augments, while 4 underwent repairs with customized augments for hybrid fixation. Follow-up averaged 26.5±15.0 months (range, 12-62 months). There was a significant increase in knee ROM, improving from 72.8°±31.9° preoperatively to 113.2°±6.8° at 12 months postoperatively ( P<0.05). VAS scores decreased from 6.6±1.4 preoperatively to 2.5±1.0 at 12 months postoperatively ( P<0.05). Similarly, KSS improved from 52.8±6.4 preoperatively to 80.7±7.9 at 12 months postoperatively ( P<0.05). There were no incidences of prosthesis displacement, poor bone integration, or postoperative infections. Conclusion:The hybrid fixation strategy employing 3D-printed porous tantalum augments has been found to be effective in addressing significant bone defects in TKA. The follow-up results indicate a satisfactory biological integration of the porous tantalum metal augments with the host bone, which has resulted in substantial improvements in pain relief and knee joint functionality.

Objective:To investigate the effect of different assisted reproductive technologies (ART) and transplanted embryos at different developmental stages on live birth sex ratio in frozen-thawed embryo transfer (FET) cycles.Methods:From April 2010 to October 2018, the clinical data of patients and neonatal underwent in vitro fertilization-frozen-thawed embryo transfer (IVF-FET), intracytoplasmic sperm injection-frozen-thawed embryo transfer (ICSI-FET) and preimplantation genetic testing-frozen-thawed embryo transfer (PGT-FET) cycles that led to birth in the Center of Reproductive Medicine, Guangzhou Women and Children's Medical Center were retrospectively analyzed. The relationship of the sex ratio of the live births to different ART and transplanted embryos at different developmental stages was studied. Results:1) IVF-FET cycles included 898 couples (920 FET cycles) and 1166 babies, with a general sex ratio of 106.7. The live birth sex ratio increased gradually at pre-morula stage, morula stage and blastocyst stage embryo transfer (99.0, 135.4, 142.6), but no statistical difference was observed between the groups ( P>0.05). 2) ICSI-FET cycles included 415 couples (433 FET cycles) and 555 babies, with a general live birth sex ratio of 111.0. After the transfer of embyos at different stages the proportion of male babies displayed no significant difference ( P>0.05). 3) PGT-FET cycles included 33 couples (33 FET cycles) and 33 babies, with a general live birth sex ratio of 153.8. Transplantation of blastocysts in IVF, ICSI or PGT had no significant effect on the proportion of male babies ( P>0.05). Conclusion:In FET cycles, compared with embryo transfer at early stage, late stage embryo transfer may be associated with a higher live birth sex ratio. The transfer of ICSI-FET embryos at different developmental stages and the transfer of blastocysts by IVF, ICSI or PGT technique did not affect the sex ratio of live birth.

One of the great challenges in assisted reproduction today is the management of cases with poor-quality oocytes. Ooplasmic transfer (OT) has been used with the aim of augmenting embryo viability in patients with multiple implantation failures, usually associated with developmentally compromised oocytes. The justification for the technique was that the ooplasm from the donor contained beneficial components lacking in the recipient's oocytes, and that the transfer of these components to the recipient's oocytes would result in normal growth and viability. This review focuses on concerns regarding its use in assisted reproduction, like mitochondrial functioning, mitochondrial DNA heteroplasmy, regulation of apoptosis, cleavage division, epigenetic modifications, oocyte contents and mRNA which are the factors affecting oocytes due to mixing of two entities. The applications, efficacy and adverse effects of OT techniques in human are summarized.
