In the clinical stage, suspected hemolytic plasma may cause hemolysis illness, manifesting as symptoms such as heart failure, severe anemia, etc. Applying a deep learning method to plasma images significantly improves recognition accuracy, so that this paper proposes a plasma quality detection model based on improved "You Only Look Once" 5th version (YOLOv5). Then the model presented in this paper and the evaluation system were introduced into the plasma datasets, and the average accuracy of the final classification reached 98.7%. The results of this paper's experiment were obtained through the combination of several key algorithm modules including omni-dimensional dynamic convolution, pooling with separable kernel attention, residual bi-fusion feature pyramid network, and re-parameterization convolution. The method of this paper obtains the feature information of spatial mapping efficiently, and enhances the average recognition accuracy of plasma quality detection. This paper presents a high-efficiency detection method for plasma images, aiming to provide a practical approach to prevent hemolysis illnesses caused by external factors.

Objective:To investigate the effectiveness of methylene blue in pain management after costal cartilage removal.Methods:A prospective, randomized controlled trial was conducted from June 2023 to March 2024. Female patients undergoing rhinoplasty with autologous costal cartilage transplantation were randomly divided into a methylene blue group and a control group. Before costal cartilage harvesting, patients in the methylene blue group received a 5 ml injection of 0.1% methylene blue solution into the skin and subcutaneous tissue of the costal cartilage donor site at the lower edge of the seventh costal cartilage or below the breast contour. Patients in the control group received an equal volume of normal saline injected into the same area. Postoperative management included routine observation and pain control (using oral analgesics and topical analgesia). Pain scores were assessed 24 hours after surgery using a visual analog scale (VAS, 0-10 points, higher scores indicate more severe pain) and a numerical rating scale (NRS, 0-10 points, higher scores indicate more severe pain), as well as the frequency of oral analgesics. Patients were followed up for postoperative complications within one month after surgery, and patient satisfaction with pain control was assessed using a self-made 5-point questionnaire (higher scores indicate greater patient satisfaction). Quantitative data were compared between groups using the independent sample t-test; qualitative data were compared between groups using the chi-square test. P<0.05 was considered statistically significant. Results:A total of 112 female patients were enrolled. Fifty-six patients were in the methylene blue group, aged (35.4 ± 5.6) years (range, 18-55 years), and 56 patients were in the control group, aged (36.1 ± 6.0) years (range, 19-54 years). The methylene blue group had significantly lower oral analgesic use 24 hours after surgery than the control group [(1.5±0.5) times vs. (4.7±1.2) times], with statistically significant differences ( P<0.05). The methylene blue group also had significantly lower VAS scores (3.2±1.2 vs. 5.8±1.3) and NRS scores (3.5±1.0 vs. 6.2±1.1) 24 hours after surgery than the control group ( P<0.05). At one-month follow-up, the incidence of postoperative complications in the methylene blue group was significantly lower than that in the control group [10.7% (6/56) vs. 21.4% (12/56)]. Patient satisfaction in the methylene blue group was significantly higher than that in the control group [4.5 ± 0.6 vs. 3.2 ± 0.8]. The differences were statistically significant ( P< 0.05). No serious adverse reactions were observed in either group. Conclusion:Methylene blue has a good analgesic effect after costal cartilage transplantation, reducing the need for analgesics, and no significant adverse reactions were observed.

Stem cell exosome therapy has shown significant potential in treating hair loss, but its safety profile has not been thoroughly studied. This paper reported a case of a 32-year-old female patient who experienced an allergic reaction following adipose-derived stem cell exosomes injection for hair loss treatment at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences in June 2023. Within 24 hours post-injection, the patient developed swelling of the forehead and right postauricular lymph nodes, accompanied by mild pain, and left posterior ear lymph nodes 48 hours later. Ultrasound examination revealed thickening of the local soft tissue and enlarged lymph nodes. The condition was diagnosed as an injection-induced allergic reaction. The symptoms gradually subsided after combined treatment with lidocaine, 5-fluorouracil, and triamcinolone acetonide injections. During a 6-month follow-up period, the patient did not experience any recurrence of allergic reactions, and the therapeutic effects remained stable. This case report highlights the potential risk of allergic reactions associated with stem cell exosome therapy for hair loss, underscoring the need for close monitoring and timely intervention in clinical applications to ensure both safety and efficacy.

Objective:
To explore a 1∶1 2D printing method of rib cartilage based on CT scanning in assisting ear framework fabrication for auricular reconstruction.
Methods:
From January 2016 to January 2017, 73 cases of microtia aging from 5 to 7 referred to our department. A 1∶1 2D printing of rib cartilage based on CT scanning was applied in preoperative assessment and measurments of bilateral sixth, seventh and eighth costal cartilage were completed before the surgery. Personalized rib cartilage ear framework fabrication was determined by the measurements.
Results:
Among the 73 cases, 58 cases received auricular reconstruction successfully. There were 15 patients whose rib cartilages did not meet the requirements and postponed the surgery. The patients who underwent auricular reconstruction were followed up for 6 to 12 months (average, 9 months). During the follow-up, 52 cases had satisfactory outcomes in size, shape, symmetry and details. No deformation of reconstructed ears or chest wall was found during the follow-up.
Conclusions
The 1∶1 2D printing based on CT scanning is a simple and timesaving way to evaluate the rib cartilage. It can be beneficial to save the amount of cartilage and improve the personalized ear framework fabrication.
