Objective To observe the clinical efficacy of Lingnan fire needle therapy combined with conventional western medicine in the treatment of mild to moderate uterine prolapse.Methods A total of 96 patients diagnosed with mild to moderate uterine prolapse in the outpatient and inpatient departments of Dongguan Humen Traditional Chinese Medicine Hospital from January 2023 to January 2024 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 48 cases in each group.Both groups received health education,and the control group received conventional western medicine treatment.The observation group received Lingnan fire needle therapy in addition to the control group's treatment.The treatment course consisted of 12 sessions,with one course completed.After treatment,the clinical efficacy of the two groups was evaluated.Changes in TCM syndrome scores,pelvic floor muscle strength,and ultrasound imaging characteristics were observed before and after treatment.The serum levels of osteopontin(OPN),connective tissue growth factor(CTGF),and matrix metalloproteinase-9/tissue inhibitor of metalloproteinase-1(MMP-9/TIMP-1)were compared before and after treatment.The safety and incidence of adverse reactions in the two groups were evaluated.Results(1)The total effective rate in the observation group was 97.92%(47/48),while it was 77.08%(37/48)in the control group.The efficacy of the observation group was superior to that of the control group,with a statistically significant difference(P＜0.05).(2)After treatment,the TCM syndrome scores and total scores in both groups significantly improved(P＜0.05),and the observation group showed significantly better improvement in these scores compared to the control group,with a statistically significant difference(P＜0.05).(3)After treatment,the pelvic floor muscle strength and ultrasound imaging characteristics in both groups significantly improved(P＜0.05),and the observation group showed significantly better improvement in these aspects compared to the control group,with a statistically significant difference(P＜0.05).(4)After treatment,the serum levels of OPN,CTGF,and MMP-9/TIMP-1 in both groups significantly improved(P＜0.05),and the observation group showed significantly better improvement in these levels compared to the control group,with a statistically significant difference(P＜0.05).(5)There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Lingnan fire needle therapy combined with conventional western medicine can significantly improve symptoms and pelvic floor muscle strength in patients with mild to moderate uterine prolapse,with notable efficacy and high safety.The mechanism may be related to the regulation of OPN,CTGF,and MMP-9/TIMP-1 levels.

Objective:To explore the teaching effect of 3D simulated wound model combined with problem -based learning (PBL) teaching in the standardized residency training of plastic surgery department. Methods:Totally 90 residents trained in the plastic surgery department of Changhai Hospital of Naval Medical University from June 2016 to September 2019 as the research objects were divided into control group and experimental group in average. The control group received traditional teaching and the experimental group accepted the 3D simulated wound model combined with PBL teaching. Then the out -department examination results and questionnaires evaluation were compared between the two groups. SPSS 19.0 was used to conduct t test on the experimental data. Results:The theoretical and practical scores of residents in the experimental group [(49.23±7.25) points and (36.38±5.29)] points were significantly better than those in the control group [(44.43±5.57) points and (28.94±6.97)] points ( P<0.05). In the questionnaire, the scores of active learning initiative, practical operation ability and clinical strain capacity of residents in the experimental group were all higher than those in the control group ( P<0.05), and there was no statistically significant difference in teamwork ability between the two groups ( P>0.05). Conclusion:The 3D simulated wound model combined with PBL teaching can be used in the teaching of standardized residency training of plastic surgery. Compared with traditional teaching, this teaching method has significant advantages and is worthy of promotion.

Objective:To investigate the application and effect of frontal flap combined with tarsalconjunctiva flap in the repair of widely full-thickness defects of the lower eyelid.Methods:From January 2016 to March 2018, 9 patients with extensive full-thickness lower eyelid defect were admitted to the Plastic Surgery Department of Changhai Hospital Affiliated to the Naval Military Medical University. All the lengths of lower eyelid defects were greater than a half of the full length. Then we designed forehead flaps combined with tarsalconjunctival flaps to cover the wounds. The second stage operation was done after 4-6 weeks to cut the pedicle and dress the eyelid.Results:All the frontal flaps of 9 patients survived. One patient had lower eyelid retraction and the lid position returned to normal half a year later. One underwent thinning surgery because of lower eyelid flap hypertrophy and one were because of pedicle hypertrophy. The appearance and function of other patients were greatly improved after surgery, and they were satisfied with the operation effect. No repair operation was performed in the future.Conclusions:The frontal flap with good quality of blood supply has a high survival rate and can be used to repair the wide defect of the lower eyelid with tarsalconjunctival flaps.

Objective: To investigate the lateral canthoplasty and canthopexy with bone drilling to correct lower eyelid malposition and its benefit. Methods: From January 2014 to January 2019, lateral canthopexy with bone drilling technique was used to repair 56 patients with lower eyelid malposition in Department of Plastic and Reconstructive Surgery of Changhai Hospital. Forty-four patients with lower eyelid ectopic had multiple previous surgeries, and 12 patients had congenital lower eyelid retraction. For patients without lower palpebral margin extension, lateral canthopexy with bone drilling technique was applied. For patients with lower palpebral margin extension, the lateral canthus angle was exposed to shorten the lower eyelid margin. For congenital lower eyelid retraction, the lateral canthus tendon was completely cut off, and then fixed with double armed sutures. Results: Operations were successfully performed on all 56 patients, and the patients were followed up for 1-38 months. Forty-nine patients achieved good eyelid shape and satisfied with the operative effects (87.5%). Malposition was ameliorated in 6 patients (10.7%). One remained uncorrected (1.8%). Conclusions Lateral canthopexy with bone drilling technique could obtain firm suspension force. For lower eyelid malposition, especially for patients with recurrent malposition or congenital lower eyelid retraction, satisfied function and appearance could be achieved.
