Ovulatory disorders are mainly characterized by abnormal follicular maturation or ovulation， with complex etiologies and a lack of effective prevention and treatment methods. Autophagy dysfunction is closely related to the generation and progression of ovulatory disorders. This article systematically elucidates the mechanisms of TCM on follicular development and ovulatory disorders from the perspective of autophagy. It also reviews relevant studies on how TCM regulates autophagy to influence follicular development and improve ovulatory disorders. The findings reveal that TCM monomers/active ingredients （leonurine， total flavonoids from Eucommia ulmoides， alpinetin， icariin， etc.） and compound formulas （including Cangfu daotan decoction， Guishen yugong decoction， Zhuluan decoction， Yishen yangluan formula， Guishen pill， etc.） improve the follicular microenvironment， regulate sex hormone levels， and reduce follicular atresia by regulating autophagy-related genes and signaling pathways such as phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin and AMP-activated protein kinase. These actions thereby promote normal follicular development and ovulation， and delay ovarian aging. Most research in this field is based on cellular and animal experiments， often focusing on a single signaling pathway or factor. Some studies fail to fully reflect the individualized treatment characteristics of TCM that emphasize “syndrome differentiation and treatment”， highlighting the urgent need for further investigation.

Objective To explore the clinical efficacy of staged surgery for non-lactating mastitis. Methods A retrospective analysis was conducted on 317 patients with non-lactating mastitis admitted to our department from January 2015 to December 2020, all of whom underwent staged surgical treatment. The recovery time, recurrence rate, and breast appearance score were observed. Results The median follow-up time was 24(17，33) months, the recovery time was (25.5±17.9) days, and the recurrence rate was 4.4%. There were 96.2% of patients satisfied with the breast appearance. Conclusions Staged surgery for non-lactating mastitis can effectively shorten the course of the disease, protect the appearance of breast, and have good clinical efficacy.

Objective:To explore the value of using the mean gamma index (GI) in targer area receiving 50% prescribed dose as reference in VMAT planned dose verification through model-based dose calculation and measurement-based dose reconstruction.Methods:Based on Compass dose verificantion system, the VMAT plans for 70 patients were validated using two method. The mean GI and passing rate in target area receiving 50% of prescribed dose area for each validation plan were obtained to evaluate its application value in dose validation. First, plan information obtained by TPS calculation was input into the Compass system for performing independent dose calculation based on the accelerator data model, and obtain a three-dimensional dose based on the independent model calculation. The planned fluence measured for each patient′s treatment plan on the accelerator was reconstructed through the Compass system to obtain a three-dimensional dose based on measurement reconstruction. The three-dimensional dose obtained by the two method were compared with the three-dimensional dose calculated by TPS.Results:Combined with the gamma criteria of 3%/3 mm in the error setting condition of GI analysis, the mean GI in the area receiving 50% of prescribed dose was evaluated. GI≤0.4 was classified as PASS, 0.4 < GI ≤ 0.6 as being clinically acceptable, and GI > 0.6 as FAIL. The VMAT planned dose verification for 70 patients showed that the model-based independent calculation was in a better agreement with the TPS calculation. The GI values were all < 0.6: GI≤0.4 for 67 patients and 0.4 90% for 88 patients and < 90% for other 2, all meeting the requirements of clinical dose verification. The model-based independent dose verification is better than the measurement-based reconstructed dose verificantion, and the difference is statistically significant ( t=15.20, 10.71, P < 0.05). Conclusions:The mean GI in target area receiving 50% of prescribed dose can be used as a reference to judge the operatability of clinical plan in clinical dose verification. The mean GI value, in combination with the comprehensive result of gamma passing rate, is more convincing to evaluate dose verification. A combination of model-based dose verification, despite time-saving and labor-saving, and the measurement-based dose verification could become a reliable dose verification method for clinical application.

【Objective】 To observe the therapeutic effects of Axitinib, a tyrosine kinase receptor inhibitor, on liver fibrosis. 【Methods】 In vivo, CCL4 was injected intraperitoneally to induce liver fibrosis in mice. After modeling, Axitinib-carboxymethyl cellulose (Axitinib-CMC) solution or CMC solution were administered by gavage. After 2 weeks of modeling, 4 weeks of modeling, 1 week of treatment and 2 weeks of treatment, the mice were killed and their liver tissues were stained by HE, Masson and α - SMA immunohistochemistry. In vitro, human hepatic stellate cell line (LX2) and human normal liver cell line (LO2) were intervened with different concentrations of Axitinib-CMC solution. MTT assay was performed 48 h and 72 h after the intervention. Flow cytometry was used to observe the apoptosis of the two cell lines. Western blotting was used to detect the expressions of Fas, Caspase-8, Caspase-3 and Bcl-2 proteins. 【Results】 HE and Masson staining results showed that CCL4 could induce liver fibrosis in the mice, and the degree of liver fibrosis was more severe in the 4-week than that in the 2-week treatment group. After treatment with Axitinib, the collagen staining area and the positive expression level of α-SMA were significantly lower than those in 4-week group and CMC treatment control group (P<0.05). In vitro, Axitinib could effectively inhibit the viability of hepatic stellate cell line LX2 and promote its apoptosis. Meanwhile, the expressions of pro-apoptotic proteins Fas, Caspase-8 and Caspase-3 increased, while the expression of apoptosis suppressor gene Bcl-2 decreased. However, the above changes were not found in control hepatocyte line LO2. 【Conclusion】 Axitinib exerts an anti-fibrosis effect by inducing apoptosis of hepatic stellate cells, and has no significant effect on normal hepatocytes.

This study aimed to explore the role of miR-130a-3p in cardiomyocyte hypertrophy and its underlying mechanisms. Pressure-overload induced myocardial hypertrophy mice model was constructed by thoracic aortic constriction (TAC). , norepinephrine (NE) was used to stimulate neonatal rat cardiomyocytes (NRCMs) and H9c2 rat cardiomyocytes to induce hypertrophic phenotypes. The expression of miR-130a-3p was detected in mice hypertrophic myocardium, hypertrophic NRCMs and H9c2 cells. The mimics and inhibitors of miR-130a-3p were transfected into H9c2 cells to observe the role of miR-130a-3p on the hypertrophic phenotype change of cardiomyocytes separately. Furthermore, whether miR-130a-3p regulated hypertrophic related signaling pathways was explored. The results showed that the expression of miR-130a-3p was significantly decreased in hypertrophic myocardium, hypertrophic NRCMs and H9c2 cells. After transfection of miR-130a-3p mimics, the expression of hypertrophic marker genes, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and β-myosin heavy chain (β-MHC), and the cell surface area were notably down-regulated compared with the control group (mimics N.C. + NE group). But after transfection of miR-130a-3p inhibitor, the expression of ANP, BNP and β-MHC in H9c2 cells increased significantly, and the cell area increased further. By Western blot, it was found that the protein phosphorylation level of Akt and mTOR were down-regulated after over-expression of miR-130a-3p. These results suggest that miR-130a-3p mimics may alleviate the degree of cardiomyocyte hypertrophy, meanwhile its inhibitor can further aggravate cardiomyocyte hypertrophy. Over-expression of miR-130a-3p may attenuate cardiomyocytes hypertrophy by affecting the Akt pathway.
