By consulting ancient herbal books and modern literature， this paper systematically sorted out and researched the processing history， relevant processing norms in recent years， modern processing technology， chemical composition changes of processed products and their pharmacological mechanism of Scutellariae Radix， in order to provide a basis for the further development of Scutellariae Radix decoction pieces. According to the textual research of ancient books， there were many kinds of processing auxiliary materials of Scutellariae Radix， such as wine， vinegar， salt， honey， pig bile and so on， among which the wine processing was the most diverse and detailed， and the processed products such as raw products， stir-fried products， wine-processed products， fried charcoal products were still in use. The modern processing techniques of Scutellariae Radix mainly focus on the processing aspects of softening and slicing， wine processing and charcoal frying， and the research methods are relatively unified. At present， it is found that the changed chemical constituents of Scutellariae Radix after processing are flavonoids， polysaccharides， volatile oils and trace elements， etc. Pharmacological effects of processed products are hemostasis， antibacterial， anti-inflammatory， antioxidant， analgesic and antipyretic， treatment of lung diseases， treatment of colitis， etc. However， in the studies of Scutellariae Radix processing， there is a lack of research on the structural changes of chemical components caused by processing and a comprehensive comparative study on the pharmacological effects of various processed products. Based on this， it is suggested to carry out systematic research on the processing technology to processing mechanism， further explore the relationship between the change rule of material basis and pharmacological action before and after processing of Scutellariae Radix， and deepen the exploration of molecular mechanism and clinical application of processed products of Scutellariae Radix， in order to clarify the scientific connotation of the processing mechanism of Scutellariae Radix， and lay a foundation for the subsequent expansion of the application of Scutellariae Radix decoction pieces and the formulation of processing standards.

Objective:To investigate the influencing factors associated with lesion residual after minimally invasive rotary mastectomy for breast masses and to construct a predictive model using columnar plots.Methods:Two hundred and twenty-eight patients with Breast lumps in Linyi People’s Hospital from Jun. 2018 to Jun. 2020 were selected as study subjects, all of whom underwent minimally invasive rotational resection, and the influencing factors of postoperative lesion residual were analyzed using univariate and multifactorial analysis, and a column line graph risk warning model was constructed and given for evaluation and validation.Results:228 patients were followed up for 6 months after surgery, 3 cases were lost, 225 cases completed postoperative follow-up, among which 185 cases (82.22%) had successfully resected lesions; 40 cases (17.78%) had residual lesions. Univariate, logistic regression analysis showed that tumor diameter ( t=15.52, P<0.001) , lesion morphology ( t=15.52, P<0.001) , lesion boundary ( χ2=7.71, P=0.006) , ultrasound guidance ( χ2=12.69, P<0.001) , and minimally invasive spinotomy system ( χ2=10.64, P=0.001) were the factors influencing lesion residual after minimally invasive spinotomy of breast masses. Based on the above factors to construct a column line graph model of lesion residual after minimally invasive rotational mastectomy for breast lumps, the area under the working characteristic curve (ROC) for model subjects was 0.974 (95% CI: 0.954-0.994) , indicating that the calibration curve basically matched the actual curve; external validation of the model showed that the area under the obtained ROC was 0.962 (95% CI: 0.933-0.991) , indicating that the model has a high degree of calibration. Conclusion:Tumor diameter, lesion morphology, lesion boundary, ultrasound guidance, and minimally invasive spinotomy system are the influencing factors of lesion residual after minimally invasive spinotomy for Breast lumps, and the column line graph model prediction of lesion residual occurring after surgery constructed based on the above factors has good confidence.

Objective:To explore the influence of tumor-associated macrophages (TAMs) on endocrine resistance in breast cancer through the forkhead box M1 (FOXM1) /Wnt/ β-catenin pathway. Methods:Tamoxifen-resistant breast cancer cells were cultured, THP-1 cells were induced into macrophages (MΦ), and further induced into TAMs. After being cultured in the conditioned medium (CM) of MCF-7 cells for 24 hours, MΦ were defined as MS cells. After being cultured in the CM of MCF-7R cells for 24 hours, MΦ were defined as MR cells. MCF-7 cells, after being cultured in the CM of macrophages for 24 hours, were defined as MCF-7 (MΦ) cells. MCF-7 cells, after being cultured in the CM of MS cells for 24 hours, were defined as MCF-7 (MS) cells. MCF-7 cells, after being cultured in the CM of MR cells for 24 hours, were defined as MCF-7 (MR) cells. Cell viability and invasion ability were evaluated using CCK-8 and Transwell assays. The protein levels of CD163, Wnt1, β-catenin, and FOXM1 in different groups were examined by qRT-PCR and Western blot. Results:Compared to the MS group (mRNA: 1.49±0.12, protein: 1.15±0.12), CD163 expression was higher in the MR group (mRNA: 2.33±0.16, protein 1.52±0.11) ( t=7.28, P=0.002) ( t=3.94, P=0.017), indicating that tamoxifen-resistant breast cancer cells can induce polarization of more MΦ into TAMs. TAMs increased the expression of FOXM1 in breast cancer cells, which further activated the Wnt/ β-catenin pathway. Compared to the MCF-7 (MΦ) group, the MCF-7 (MS) and MCF-7 (MR) groups showed enhanced cell viability and invasion, with the most significant increase observed in the MCF-7 (MR) group. Compared with MCF-7 (MΦ) cells, the levels of Wnt1, β-catenin, and FOXM1 in MCF-7 (MS) and MCF-7 (MR) cells were significantly increased, with the highest levels observed in the MCF-7 (MR) group with the most TAM polarization. Compared to the MCF-7 group, both the MCF-7 (MR) and MCF-7+pcDNA-FOXM1 groups showed increased levels of Wnt1 and β-catenin, enhanced cell viability and invasion. Compared to the MCF-7 (MR) group, the MCF-7 (MR) + si-FOXM1 group showed reduced levels of Wnt1 and β-catenin, weakened cell viability and invasion. Conclusion:TAMs promote endocrine resistance in breast cancer by upregulating FOXM1 and activating the Wnt/ β-catenin pathway.

Objective To preliminarily verify the effectiveness and safety of bloodletting combined with drug bamboo cups in intervention of degenerative lumbar spinal stenosis,and to explore the prognostic factors that affect the efficacy of TCM regimens in the treatment of DLSS.Methods 64 consecutive patients with degenerative lumbar spinal stenosis were enrolled.Bloodletting combined with drug bamboo cup intervention was used.Acupoints were selected and treated with the same length of the governor channel of the lumbar spine,the first and second side lines of the bladder meridian and Ashi point,weekly 2 times,8 times per course,2 consecutive courses of treatment.Before treatment,after treatment,and 1 month follow-up,the changes of the patient's lumbar spinal stenosis specific scale(SSM),modified Oswestry dysfunction index(ODI),and 12 health survey summary scores(SF-12)were observed.Using SSM symptom or function score≥0.5,the criteria for grouping were first single-factor analysis,and then logistic regression was used to analyze the prognostic factors of the treatment.Results After 2 courses of treatment,the patient's SSM symptom score(2.25±0.56),SSM function score(2.06±0.67),ODI index(15.49±8.72),and SF-12 physiological score(36.31±7.35)were more significant than before treatment Improved,the difference was statistically significant(P<0.05),the SF-12 psychological score(49.70±9.47),the difference was not statistically significant compared with before treatment(P>0.05);the patient's SSM symptom score(2.22±0.54)was followed up for one month,SSM function score(2.09±0.66),ODI index(15.53±8.23),SF-12 physiological score(36.55±7.25),SF-12 psychological score(50.62±9.17),which are significantly better than before treatment,and the difference is statistically significant(P<0.05),the difference was not statistically significant(P>0.05)after 2 courses of treatment.The univariate logistic regression analysis of each influencing factor showed that:BMI,baseline symptom dimension,baseline functional dimension,foraminal stenosis,lateral recess stenosis,and two-stage stenosis had statistically significant differences between the effective and ineffective groups(P<0.05).Conclusion Bloodletting combined with drug bamboo cups has a certain clinical effect on degenerative lumbar spinal stenosis.
