Breast cancer surgery has been changing from radical mastectomy to modified radical mastectomy and breast-conserving surgery with less trauma and fewer complications. Breast conserving surgery has evolved into oncoplastic breast conserving surgery, which combines both breast conserving and plastic surgery. The application of autologous tissue flap is a research hotspot in oncoplastic breast conserving surgery. This article reviews the indications and contraindications of tissue flap technology in breast cancer, surgical methods and categories, application occasions of different types of tissue flaps, early and delayed postoperative complications, and the impact of different postoperative adjuvant treatments on tissue flaps, based on the latest research on oncoplastic breast conserving surgery both domestically and internationally.

Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.

The dried rattan stem of the Fibraurea Recisa Pierre plant contains the active ingredient known as fibrauretine (FN). Although it greatly affects Alzheimer's disease (AD), the mechanism of their effects still remains unclear. Proteomics and transcriptomics analysis methods were used in this study to determine the mechanism of FN in the treatment of AD. AD model is used through bilateral hippocampal injection of Aβ1-40. After successful modeling, FN was given for 30 days. The results showed that FN could improve the cognitive dysfunction of AD model rats, reduce the expression of Aβ and P-Tau, increase the content of acetylcholine and reduce the activity of acetylcholinesterase. The Kyoto Encyclopedia of Genes and Genomes enriched differentially expressed genes and proteins are involved in signaling pathways including metabolic pathway, AD, pathway in cancer, PI3K-AKT signaling pathway, and cAMP signaling pathway. Transcriptomics and proteomics sequencing resulted in 19 differentially expressed genes and proteins. Finally, in contrast to the model group, after FN treatment, the protein expressions and genes associated with the PI3K-AKT pathway were significantly improved in RT-qPCR and Western blot and assays. This is consistent with the findings of transcriptomic and proteomic analyses. Our study found that, FN may improve some symptoms of AD model rats through PI3K-AKT signaling pathway.

Background::The differential diagnosis of mucoepidermoid carcinoma (MEC) from neoplasm undergoing mucinous features brings more pitfalls to pathologists. Combining specific MAML2 gene rearrangement and histological characteristics may be the solution. Methods::Twenty-five tumors with mucinous components were selected for differential diagnosis of MEC. All the cases were detected for MAML2 gene rearrangement. The cases diagnosed as MEC were classified into four variants: classic, oncocytic, Warthin-like, and nonclassified, and they were graded using the Brandwein system. The histological characteristics of non-MECs were summarized for differential diagnosis. Univariate survival analysis was performed on MECs. Results::There were 16 MECs; 62.5% were MAML2 rearranged. For the low-, intermediate-, and high-grade MECs, the rate of rearrangement was 83.3%, 100%, and 28.6%, respectively. Both the oncocytic and Warthin-like MECs were MAML2 rearranged. For the classic and nonclassified MECs without MAML2 rearrangement, non-keratinized squamoid cells and distinctive mucinous cells were essential diagnostic criteria. On survival analysis, all the disease progression occurred in high-grade MECs ( p = 0.038). Nine cases were diagnosed as non-MECs: pleomorphic adenoma with mucinous metaplasia showed no ex-capsular involvement; metaplastic Warthin tumor appeared with overt keratinization and residual oncocytic bilayered epithelium; mix squamous cell and glandular papilloma showed an endobronchial papillary growing pattern; adenosquamous carcinoma was accompanied by squamous carcinoma in situ of the overlying mucosa. All the non-MECs were negative for MAML2 rearrangement. Conclusion::The application of combining MAML2 rearrangement and histological characteristics is helpful in the differential diagnosis between MEC and other tumors with mucinous components.

Anaplastic lymphoma kinase (ALK) is the most common fusion gene involved in non-small cell lung cancer (NSCLC), and remarkable response has been achieved with the use of ALK tyrosine kinase inhibitors (ALK-TKIs). However, the clinical efficacy is highly variable. Pre-existing intratumoral heterogeneity (ITH) has been proven to contribute to the poor treatment response and the resistance to targeted therapies. In this work, we investigated whether the variant allele frequencies (VAFs) of ALK fusions can help assess ITH and predict targeted therapy efficacy. Through the application of next-generation sequencing (NGS), 7.2% (326/4548) of patients were detected to be ALK positive. On the basis of the adjusted VAF (adjVAF, VAF normalization for tumor purity) of four different threshold values (adjVAF < 50%, 40%, 30%, or 20%), the association of ALK subclonality with crizotinib efficacy was assessed. Nonetheless, no statistical association was observed between median progression-free survival (PFS) and ALK subclonality assessed by adjVAF, and a poor correlation of adjVAF with PFS was found among the 85 patients who received first-line crizotinib. Results suggest that the ALK VAF determined by hybrid capture-based NGS is probably unreliable for ITH assessment and targeted therapy efficacy prediction in NSCLC.

ObjectiveTo screen the preparation technology of Baoyuan chewable tablets and to preliminarily elucidate its anti-fatigue effect and mechanism. MethodTaking encapsulation rate of volatile oil， extract rate and extraction rate of active ingredients as indexes， single factor test and orthogonal test were used to optimize the volatile oil inclusion， aqueous decoction and formulation molding processes of Baoyuan chewable tablets. ICR rats were randomly divided into the blank group， model group， Gaoshan Hongjingtian oral liquids group（6.01 mL·kg^-1） and and Baoyuan chewable tablets low， medium， and high dose groups（2.1， 4.2， 8.4 g·kg^-1）， 8 mice in each group， and were administered by gastric gavage at the corresponding dose once a day， the blank and model groups were given equal volume of saline for 15 d. After the last administration for 30 min， the mice were loaded with 5% of the body mass of lead at the tail and swam until exhaustion to establish the fatigue model， and the weighted swimming time of the mice in each group was recorded， meanwhile， the muscle tissues of the mice were sliced， stained by hematoxylin-eosin（HE） and subjected to pathological observation， and the levels of blood urea nitrogen（BUN）， lactic acid（LA）， liver glycogen（LG）， activities of lactate dehydrogenase（LDH） and creatine kinase（CK） in the serum were determined. ResultThe optimal inclusion process of cinnamon oil in Baoyuan chewable tablets was 10∶1 for β-cyclodextrin-volatile oil， and inclusion at 50 ℃ for 2 h with saturated aqueous solution method. The optimal water extraction process was to extract twice， adding 10 times of water to extract for 50 min for the first time， and adding 9 times of water to extract for 40 min for the second time. The ratio of the extract of Baoyuan chewable tablets with microcrystalline cellulose， maltodextrin， mannitol， citric acid， magnesium stearate was 63∶13∶8∶17∶17∶1∶1， the tablets were pressed by wet granulation， the each tablet weight was 1.2 g， and the hardness was 60-80 N. Compared with the model group， Baoyuan chewable tablets low， medium， and high dose groups could significantly prolong the exhaustion time of mice in weight bearing swimming（P<0.05， P<0.01）， and improve the exercise endurance of the body， and the results of HE staining showed that all dose groups of Baoyuan chewable tablets could significantly improve the muscle tissue damage caused by exercise， significantly reduce the levels of BUN， LA and the activities of LDH and CK in serum（P<0.01）， and significantly increase the content of LG（P<0.05， P<0.01）. ConclusionThe optimized preparation process of Baoyuan chewable tablets is stable and feasible， and the preparation can improve exercise endurance by increasing the LG level in liver tissue， and relieve muscle soreness by accelerating the removal of LA from the body， and reduce CK and LDH activities to exert anti-fatigue effects.

Objective:To explore the application and teaching effect of TSPV (short for theoretical teaching, simulated surgical skills training, practical surgery training, and video-based review) 4-step teaching in skill training of gynecologic laparoscopic surgery.Methods:A total of 30 trainees who participated in gynecologic laparoscopic surgery training were randomly divided into two groups, with 15 in each group. The experimental group received TSPV 4-step teaching, while the control group adopted traditional teaching and completed training and assessment in stages. The general data, training assessment results, teaching feedback and satisfaction survey of the two groups were compared and analyzed. SPSS 20.0 was used for t-test and Chi-square test. Results:There was no statistical difference in age, gender distribution, education background, clinical working experiences and other general data between the two groups. There was no significant difference in the theoretical examination scores between the two groups [(85.3±4.6) vs. (83.4±4.3), P=0.252]. The scores of simulated operation assessment [(91.7±5.2) vs. [(72.4±5.9), P<0.001] and clinical practice assessment [(88.5±4.8) vs. (82.7±6.7), P=0.011] in the experimental group were better that those in the control group. In addition, the experimental group had a better overall evaluation of teaching satisfaction. Conclusion:TSPV 4-step teaching is a more optimized and popular gynecologic laparoscopic training mode, which is recommended to further promote the validation in teaching.
