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 investigate the molecular mechanism of NOD-like receptor(NLR) signaling pathway induced cellular focal death in mouse kidney tissues under plateau hypoxia based on transcriptomic sequencing technology. Methods: Animal models were constructed in high-altitude kidney test group(HKT group) and plain kidney control group(PKC group),and C57/BL6 mice were bred at an altitude of 4 200 m and 400 m,respectively.Kidney tissues were aseptically taken out after 30 d and used for observation of renal histopathological changes and transcriptomics sequencing,respectively,and then differentially expressed genes(DEGs) were enriched by KEGG and GO analysis.Key gene and protein expression levels were verified by reverse transcription quantitative polymerase chain reaction(RT-qPCR) and Western blot analysis. Results: Hematoxylin-eosin(HE) staining showed that the renal tubules of HKT mice were disorganized,and the tubular epithelial cells were edematous with inflammatory cell aggregation.Transcriptomics sequencing analysis revealed that a total of 3 007 DEGs were identified in the HKT group,and KEGG analysis showed that DEGs were significantly enriched in the NLR signaling pathway.The mRNA expression of the key differentially expressed genes,CASP1,CASP11,GSDMD,IFI16,NAIP5,IRF9,and the downstream inflammatory factors,IL-1β and IL-18,was upregulated,and protein expression of CASP1,CASP11,and GSDMD was up-regulated. Conclusion The plateau hypoxic environment induces cellular pyroptosis by regulating the expression of NLR signaling pathway and releases downstream inflammatory factors to cause inflammatory responses.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Objectives:To report a novel mutation site in the pathogenic gene TTR of transthyretin cardiac amyloidosis(ATTR-CA),and to identify family members at risk,and provide suitable clinical diagnosis and treatment. Methods:A retrospective analysis was conducted on the clinical data of the proband with ATTR-CA who visited the Department of Cardiology,the First Affiliated Hospital of Zhengzhou University in March 2021.The proband underwent whole exome sequencing using high-throughput methods to detect mutation genes.Sanger sequencing was used to test candidate pathogenic loci in suspected family members,and relevant literature was reviewed. Results:Among 51 individuals spanning 5 generations in the pedigree,10 family members(including the proband)carried the heterozygous TTR gene c.163A>G mutation,resulting in the amino acid residue at position 55 changing from lysine(Lys)to glutamic acid(Glu).This mutation follows an autosomal dominant inheritance pattern,with early onset in adulthood,rapid progression,and presenting as a mixed-type ATTR-CA.Five mutation carriers had different clinical manifestations,while the remaining 5 mutation carriers,who are at younger age,have not yet shown symptoms.Within the pedigree,7 individuals died(the proband's uncle[Ⅱ-1]who died from stroke at 65 years old,the rest 6 family members died from heart disease before the age of 50). Conclusions:According to the American College of Medical Genetics and Genomics guidelines,TTR gene Lys55Glu mutation is classified as likely pathogenic,this mutation site has not been reported in the literature before.Present study adds clinical evidence that might broaden the spectrum of TTR mutations.
