Granulomatous mastitis in a 50-year-old male: A case report and review of literature.

BACKGROUND: Granulomatous mastitis (GM) an inflammatory disease of the breast that usually affects women of childbearing age, occurs very rarely in males. CASE SUMMARY: We present a case study of a 50-year-old male patient with GM. The patient developed a breast lump following the cleaning of a previously embedded dirt-filled nipple. While an initial improvement was noted with antibiotic therapy, a recurrence occurred a year later, showing resistance to the previously effective antibiotics. Subsequently, the lesion was excised. The histopathological examination confirmed the diagnosis of GM. CONCLUSION: GM should be considered a possible diagnosis of male breast masses.

Cardioprotective effect of Chinese herbal medicine for anthracycline-induced cardiotoxicity in cancer patients: A meta-analysis of prospective studies.

BACKGROUND: To assess the benefits and harmful effects of Chinese herbal medicine (CHM) formulations in preventing anthracyclines (ANT)-induced cardiotoxicity. METHOD: The Cochrane Library, Pubmed and EMBASE databases were electronically searched for relevant randomized controlled trials (RCTs) published till December 2021 in English or Chinese-language, in addition to manual searches through the reference lists of the selected papers, and the Chinese Conference Papers Database. Data was extracted by 2 investigators independently. RESULT: Seventeen RCTs reporting 11 different CHMs were included in this meta-analysis. The use of CHM reduced the occurrence of clinical heart failure (RR 0.48, 95% CI 0.39 to 0.60, P < .01) compared to the control group. Data on subclinical heart failure in terms of LVEF values showed that CHM reduced the occurrence of subclinical heart failure (RR 0.47, 95% CI 0.35 to 0.62, P < .01) as well. CONCLUSION: CHM is an effective and safe cardioprotective intervention that can potentially prevent ANT-induced cardiotoxicity. However, due to the insufficient quality of the included trials, our results should be interpreted with cautious.

Clinical observation on the effect of Chinese medicine-"TCM formula" intervention on recurrence and metastasis of triple negative breast cancer.

OBJECTIVE: This study used a prospective cohort study to observe the effect of triple-negative breast cancer on the 2-year disease-free survival rate with or without "TCM formula". METHODS: From November 1 st, 2016, the first patient was enrolled in the cohort study. A total of 356 patients were enrolled on January 30, 2019. Among them, 154 cases were followed up for 2 years. During the follow-up, there were 6 cases of shedding, so 6 cases were affected. A total of 148 cases were included in the analysis, including 73 in the exposed group and 75 in the non-exposed group. The exposed group was given "TCM formula" on the basis of standardized treatment, and the non-exposed group was treated with simple triple-negative breast cancer. The two groups visited each of the three months. The interview included safety examination (hematology and imaging). The endpoint was the difference in 2-year invasive disease-free survival between the exposed and non-exposed groups and the safety of the "TCM formula". RESULTS: There were 6 cases of shedding during the experiment and the shedding rate was 3.9 %. The 2-year rate of invasive disease-free survival in the exposed team was 88.7 % and the non-exposed group was 82.5 %. Logistic multivariate regression analysis predicted that "TCM formula" could reduce the disease-related recurrence and metastasis rate by 11 % (OR = 0.89, 95 % CI 0.37-0.956, P＜0.05). Through K-M survival analysis, TNBC patients with age ≤35 years and regional lymph node stage N1 may be the benefit group of "TCM formula"(P＜0.05). During the study, the incidence of total adverse events was 8.2 % in the exposed group, mainly manifested as stomach discomfort, diarrhea, and hepatocyte damage. CONCLUSION: 1. In the exposed group, the two-year rate of invasive disease-free survival increased by 6.2 % compared with the non-exposed group(P＞0.05). 2. According to K-M survival analysis, TNBC patients with age ≤35 years and regional lymph node metastasis to N1 may be potential beneficiaries of "TCM formula". 3. "TCM Formula" is safe and tolerable to most patients.

[Ruyiping Inhibited Pulmonary Metastasis of Breast Cancer by Regulating the Formation of Pre-metastasis Microenvironment].

Objective To observe the effect of Ruyiping (RYP, a recipe for fighting against re- currence and metastasis of breast cancer) on pre-metastatic microenvironment, and to study its possi- ble mechanism. Methods The experiment was divided into two parts. The 1st part lies in setting the pre- cancerous transfer, and the 2nd part lies in the effect of RYP on pre-metastatic microenvironment. There were 24 BALB/c mice in the 1st part. Logarithmic phase 4T1 cells were dispensed into cell suspension. Blood cells were counted by blood cell counter. Then they were injected into the 4th mammary fat pad of the 24 BALB/c mice under aseptic condition (1 x 106 cells/mL, 0.1 mL for each mouse). There were 60 BALB/c mice in the 2nd part. They were divided into the blank group, the model group, low, middle, high dose RYP groups by random digit table, 12 in each group. The modeling method was the same as men- tioned above. Medication was started from the 2nd day of inoculation. Mice in low, middle, high dose RYP groups were administered with 5. 13, 10. 26, 20. 52 g/kg RYP crude drugs per day by gastrogavage, once per day for 14 successive days. Equal volume of normal saline was administered by gastrogavage to mice in the blank group and the model group. Six mice were sacrificed at day 10, 14, 18, and 22, respectively in the 1 st part of the experiment. The pulmonary metastasis was observed. The histology and mi- cromorphology of lung tissues were observed under light microscope and electron microscope/transmission electron microscopy (TEM) in the 2nd part of the experiment. The relative pulmonary vascular per- meability was determined by Evans blue. The effect of RYP on the formation of pre-metastatic microenvironment was observed. The levels of angiogenin2 (Angpt2), vascular endothelial growth factor (VEGF) , IL6 and IL1 ß were detected by Western blot and Real time PCR. Results The period from day 0 to day 14 was considered to be the pre-metastatic phase. Compared with the model group, significant inhibition on the tumor weight and tumor volume were shown in middle and high dose RYP groups (P <0. 05,P <0. 01). RYP dose-dependently inhibited the tumor weight and tumor volume (P <0. 05,P <0. 01). Infiltration of lymphocytes occurred in the model group and the low dose RYP group. But there was no statistical difference in the morphology of lung tissue in light microscopic results between middle/high dose RYP groups and the blank group. The pulmonary blood vessel net was consisted of continuously densely capillaries. The structure of pulmonary capillaries was normal in the blank group. The blood vessel walls were not regular and even in the model group, with obviously distended capillaries. After treated by RYP, the injury was improved, with normal basic morphology of blood vessels. Compared with the blank group, the exudate in Evans blue was obviously increased, protein and mRNA expressions of Angpt2, VEGF, IL6, and IL1ß were increased in the model group (P <0. 05,P <0. 01). Compared with the model group, the exu- date in Evans blue was obviously decreased in each YRP group. The reduction of the exudate was dose- dependently with the dose of YRP (P <0. 01). Protein and mRNA expressions of VEGF in the middle dose RYP group, protein and mRNA expressions of Angpt2, VEGF, IL6, and ILI1ß were decreased in middle and high dose RYP groups (P <0. 05,P <0. 01). Protein expressions of IL6 were decreased in the middle dose RYP group (P <0. 01). Conclusions RYP had favorable regulation in the tumor growth and the formation of pre-metastatic microenvironment. It could protect the integrity of vascular system, inhibit the formation of pre-metastatic microenvironment possibly through inhibiting the expressions of Angpt2, VEGF, IL6, and IL11ß, and finally inhibiting the occurrence of pulmonary metastasis of breast cancer.
