Objective:To investigate the clinical application of internal mammary perforator (IMP) as recipient vessels in immediate breast reconstruction using deep inferior epigastric perforator (DIEP) flap.Methods:The clinical data of 10 patients with early breast cancer who underwent DIEP for immediate breast reconstruction using IMP as the recipient vessels from January 2022 to December 2023 were analyzed. The number, position, and diameter of IMP, diameter of DIEP, the size of the flap, the operation time, surgical complications, cosmetic effect of breast, and patients' satisfaction were summarized and analyzed.Results:The number of IMPs was 2-3, and they were distributed in the second to the fourth ribs. The diameter of the IMP artery was (1.15±0.22) mm, and the diameter of the vein was (1.35±0.19) mm. The diameter of the DIEP was (1.55±0.28) mm, and that of its accompanying vein was (1.50±0.23) mm. The sizes of the flaps ranged from 10.0 cm×8.0 cm×3.0 cm to 12.0 cm×22.0 cm×4.0 cm, with an average of 20.5 cm×11.2 cm×2.8 cm. The weight of the flap was (389.1±51.5) g. The operation time was (574.8±68.1) min. All 10 cases of flaps survived. The reconstructed breasts were natural, soft, and symmetrical to the healthy side breasts. There was no obvious operative complication. The average BREAST-Q score of the patients was 93.5. No recurrence or metastasis was found during follow-up.Conclusions:Although technically difficult, using IMP as recipient vessels in DIEP flats for immediate breast reconstruction results in a low complication rate of the injuries in the internal mammary region. Under the premise of strictly adhering to the surgical indications, satisfactory results can be achieved, and it is safe and reliable.

Objective:To summarize the clinical researches of Wumei Pill and provide reference for clinical application and follow-up research.Methods:The databases CNKI, VIP, Wanfang, CBM, PubMed, Embase were retrieved from the inception to June 30,2022. CiteSpace 6.1.R3 software was used to analyze the research hotspots and keywords in the literature. Using EndNote X9 software and Microsoft Office Excel 2013, we recorded and analyzed the published year, literature type, affiliated journal, disease treated, TCM syndrome type, single drug dose and treatment duration of the included articles.Results:212 articles were included. Diarrhea, gastritis, diabetes, insomnia were the research hotspots. The types of diseases treated by Wumei Pill mainly include digestive system, endocrine system and tumor, mainly for cold-heat syndrome and Jueyin syndrome. The average dosage of Mume Fructus was the largest, 21 g. The average treatment time was 5.78 weeks. Conclusion:At present, the overall clinical research of Wumei pill shows an increasing tendency, mainly involving gastrointestinal disease.

Objective:To assess the efficacy and safety of acupuncture compound anesthesia(ACA)for traditional thyroidectomy. Methods:Randomized controlled trials(RCTs)studying the use of ACA for traditional thyroidectomy were retrieved from PubMed,Excerpta Medica Database(EMBASE),Cochrane Library,Web of Science,China National Knowledge Infrastructure(CNKI),Chongqing VIP Database(CQVIP),Wanfang Academic Journal Full-text Database(Wanfang),and China Biology Medicine Disc(CBM)from inception to September 30,2021.Two investigators independently extracted data and assessed the risk of bias and quality of the studies.Anesthesia effectiveness was the primary outcome,while the secondary outcomes included various pain scales,vital signs,analgesic consumption,and adverse events.Review Manager 5.3 was used for meta-analysis.Weighted mean difference(WMD),standardized mean difference(SMD),and confidence interval(CI)were used for statistical descriptions. Results:A total of 16 papers were included,involving 1228 patients.Meta-analysis showed that anesthesia effectiveness was significantly improved after adding acupuncture as an adjunct[SMD=0.62,95%CI(0.40,0.83),P<0.0001,I2=36%].Besides,ACA can also moderate vital signs and reduce the feeling of pain[SMD=-1.61,95%CI(-2.61,-0.61),P<0.00001,I2=95%],analgesic consumption,and adverse events.Subgroup analysis of the electroacupuncture(EA)group further revealed that the effectiveness of low-frequency EA[WMD=0.43,95%CI(0.30,0.55),P<0.00001,I2=15%]and the entire operative stimulation of EA[WMD=0.55,95%CI(0.33,0.77),P<0.00001,I2=0%]was significantly better than high-frequency EA and short-time stimulation of EA during the operation.Further,no significant difference existed between conventional analgesia and acupuncture analgesia. Conclusion:ACA is beneficial to traditional thyroidectomy regarding efficacy and safety when acupuncture is applied as an adjunct.However,additional high-quality studies with larger sample sizes are needed to verify the findings.

Objective To study the effects of different root control attachment on root control and periodontal ligament （PDL） stress during canine distal translation in plastic aligner-based orthodontic treatment. Methods Through three-dimensional (3D) finite element technology, 11 models composed of 4 attachments and 3 kinds of loading were established. Namely, attachment A: no attachments; attachment B: traditional vertical rectangular attachment; attachment C: 1/4 spherical double optimized attachment; attachment D: double optimized door arch attachment; load a: 0.15 mm distal translation of the canine; b: load a+ application of 30 N·mm counterclockwise torque to stress surface of the attachment; load c: load a+ application of 30 N·mm counterclockwise torque to the entire crown. The root control effect of distal translation of the right maxillary canine was simulated with plastic aligner under different loads. Results Displacement modes of all models were distally tipped translation. The double optimized door arch attachment showed the optimal root control effect during canine distal translation. The root control effect for two groups of double optimized attachment was better than that of traditional rectangular attachment. The effect of adding attachments on root control of the canine was better than that of applying only counterclockwise couple. The PDL stress mainly appeared in distal alveolar ridge and root apex without attachment, while the PDL stress mainly appeared in distal alveolar ridge with attachment. Conclusions The most suitable measure to improve the effect of root control during canine distal translation is to use the double optimized door arch attachment in clinic.
