Objective To explore the indication,surgical procedure and the postoperative treatment of breast conserving modified radical mastectomy for early stage breast cancer .Methods The clinical data of 21 patients with early stage breast cancer underwent breast conserving modified radical mastectomy were analyzed retrospectively. Results All patient recovered uneventfully. All the external configuration of the breast were fine. There were no recurrence and no complications in this series. Conclusions The breast conserving modified radical mastectomy is recommended for the early stage breast cancer. The external configuration of breast is fine postoperatively, and patients have higher survival quality.But follow up is necessary in order to find and treat the recurrence of breast cancer.

OBJECTIVETo explore the effect of Zhenqing Recipe (ZQR) on renal structure and expressions of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in experimental type 2 diabetic rats.

METHODSThe rat models of type 2 diabetic were set up by intraperitoneally giving small-dose streptozotocin (STZ) after fed with high carbohydrate and high fat diets for one month. The model rats were randomly divided into the model group,the high and low dose ZQR-treated groups,and the enalapril-treated group; a normal control group was also established. The course of treatment continued 8 weeks. The expressions of MMP-9, TIMP-1, and fibronectin (FN) in renal tissues were detected by immunohistochemistry. The morphological changes of glomeruli and renal tubules were checked by microscopy.

RESULTSCompared with the normal control group, the expression of TIMP-1 and FN increased and MMP-9 decreased in the model group; the treated groups could decrease the expressions of TIMP-1 and FN, and increase the expression of MMP-9, especially the high-dose ZQR group had the best effect. The morphological changes of renal tubules and glomerulus in the treated groups were improved better as compared with the model group.

CONCLUSIONThe protective effect of ZQR on renal structure may be achieved by modulating the expressions of MMP-1 and TIMP-1.

Objective:To analyze the clinical characteristics of patients with nocardiosis, so as to improve the diagnosis and treatment of nocardia infection in the future.Methods:From May 2016 to October 2020, 24 patients with nocardiosis in Xiangya Hospital, Central South University were enrolled, and their clinical data including clinical features, laboratory examinations, imaging findings, diagnosis and treatment process, and outcome were retrospectively analyzed.Results:Among the 24 patients with nocardiosis, 18 cases (75.0%) were males, and the median age was 54.5 years.Twenty-three patients had underlying diseases, of which the most common disease was antineutrophil cytoplasmic antibody-related vasculitis (16.7%(4/24)). Of nine species of Nocardia identified from the 24 patients, Nocardia farcinica was the most common species (seven cases). The lesion sites were mainly lungs (70.8%(17/24)), skin and soft tissues (42.0%(10/24)), brain (25.0%(6/24)) and blood system (17.0%(4/24)). There were 12 cases (50.0%) of patients with more than two lesion sites. The clinical manifestations, imaging examinations and laboratory tests of the 24 patients were not specific. The diagnosis depended on the etiology. Nineteen patients received trimethoprim-sulfamethoxazole-based combination therapy, and two were discontinued due to adverse reactions of sulfa drugs. After treatment, 19 cases (79.2%) were improved and five cases (20.8%) died. Conclusions:Patients with nocardiosis often have atypical clinical manifestations, and multiple organs are easily affected.Early and accurate identification and rapid and effective anti-biotic therapy are the keys to improve the overall prognosis of these patients.

OBJECTIVE To explore the material basis and mechanism of expectorant and cough relief effects of the fruits of Phellodendron chinense var. glabriusulum Schneid. METHODS The expectorant and cough relief effects of volatile oil and water decoction of the fruits of P. chinense var. glabriusulum Schneid. were studied by ammonia water cough induction and drug expectorant model mice experiments； GC-MS and UPLC-MS technologies were used to identify its volatile oils and non-volatile components of the fruits of P. chinense var. glabriusulum Schneid. The active ingredients， core targets and pathways of expectoration and cough relief were analyzed by network pharmacology. RESULTS The volatile oil （0.8， 0.2 g/kg， calculated by volatile oil） and water decoction （12， 3 g/kg， calculated by crude drug） of the fruits of P. chinense var. glabriusulum Schneid. both had obvious expectorant and cough relief effects， and showed obvious dose-dependent relationship. A total of 38 volatile oil components were identified from the medicinal herbs， and the relative percentage contents of 8 components were greater than 1%， such as α -pinene， myrcene， β -caryophyllene， germanene D， isospathulenol； a total of 69 non-volatile oil components were identified， mainly including phenolic compounds， alkaloids， and flavonoids. The active ingredients screened from the identified components included 13 compounds such as α-pinene， myrcene， chlorogenic acid， luteolin， berberine. There were a total of 55 intersection targets with diseases， and the core targets were tumor necrosis factor （TNF）， epidermal growth factor receptor （EGFR）， vascular endothelial growth factor A （VEGFA）， serine/threonine kinase proteins （AKT1） and Toll-like receptor 4 （TLR4）. The molecular docking results showed that the active ingredients and the core targets had good binding ability. GO functional analysis found that the targets were significantly enriched in biological processes such as the reaction affecting lipopolysaccharides， the positive regulation of peptidyl serine phosphorylation， and the positive regulation of the biosynthesis process of nitric oxide. KEGG pathway enrichment analysis found that the targets were significantly enriched in the signaling pathways such as cancer， non-small cell lung cancer， proteoglycans in cancer. CONCLUSIONS Fruits of P. chinense var. glabriusulum Schneid. have obvious expectorant and cough relief effects， and its material basis may be α-pinene， myrcene， chlorogenic acid， luteolin， berberine， etc.， and mainly act on TNF， EGFR， VEGFA， AKT1， TLR4 and its significantly enriched signaling pathway.
