Objective:This study was conducted to evaluate whether or not immediate breast reconstruction influences quality of life and patient body image satisfaction outcomes among Chinese women with breast cancer compared with modified radical mastecto-my. Methods:Sixty patients with breast cancer and were operated from July 2011 to July 2012 in Cancer Institute&Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were included. These patients were divided into two groups:Ⅰ(30 patients) underwent modified radical mastectomy andⅡ(30 patients) underwent mastectomy with immediate breast reconstruction. Pa-tient satisfaction with breast reconstruction was evaluated by functionally assessing cancer therapy-breast cancer scale (FACT-B) and the scales that we designed. Results:No significant differences were observed between the two groups in terms of baseline characteris-tics, histopathological characteristics, and incision conditions (P>0.05). The patients in groupⅡ(immediate breast reconstruction) ex-hibited improved body image satisfaction outcomes (41.1 ± 10.8 vs. 33.2 ± 8.8, P=0.003);this difference was still observed after adjust-ment for confounding factors was performed by multiple linear regression. No significant difference was found between the two groups in terms of total FACT-B score and psychological evaluation score (P>0.05). Conclusion:Chinese women who prefer immediate breast reconstruction exhibited an improved body image satisfaction.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

Objective:Occult breast cancer (OBC) accounts for 0.3%-1.0%of all breast cancers. Because of the rarity of this dis-ease, its treatment and prognosis remain unclear. Our study evaluated the treatment outcomes and prognostic factors associated with OBC. Methods:A total of 82 patients diagnosed with OBC based on available criteria were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China, between January 1968 and June 2014. Except for 16 patients who were treated by needle biopsy or excisional biopsy only and were subsequently excluded, all of the cases reported were included in the study. Of the remaining 66 patients, one was male. Patient data, tumor characteristics, and treatment and outcome variables were evaluated. Overall survival (OS) and disease-free survival (DFS) were analyzed. A unicentric retrospective review of 66 patients with OBC was performed. Re-sults:The median follow-up was 75.5 months (7.0-328.0). No significant differences in OS and DFS were observed between patients who underwent mastectomy plus axillary lymph node dissection (Mast+ALND) and those who underwent breast conservation surgery (P>0.05). Univariate analysis revealed that nodal status is a significant prognosis factor of DFS (P=0.031). Conclusion:No significant difference in treatment outcomes between mastectomy+ALND and breast conservation surgery was observed. Nodal status may be an independent predictor of poor outcomes in OBC patients.

Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.

OBJECTIVETo evaluate whether the medicinal serum of Yi-shen Ruan-jian san can antagonize the fibrogenic effect of human proximal tubular epithelial cell line (HKC) activated by aristolochic acid (AA) in vitro.

METHODThe HKC was incubated in the media containing 40 mg x L(-1) aristolochic acid sodium salt (AA-Na) with or without 10% concentration of Yi-shen Ruan-jian san medicinal serum. Then the cell proliferation and cytotoxicity of HKC were determined by MTF and lactate dehydrogenase (LDH) release assay respectively, the antigen expression of cytokeratin and alpha-smooth muscle actin on HKC was detected by immunocytochemistry, the mRNA expression of transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF), plasminogen activator inhibitor-1 (PAI-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and type I Collagen (Col I) of HKC was measured by RT-PCR, and their protein expression was measured by ELISA or Western blot.

RESULTNo cytotoxic effect was found in HKC after stimulation of AA-Na with or without the medicinal serum of Yi-shen Ruan-jian san (P > 0.05). No epithelial-myofibroblast transdifferentiation was found in HKC after AA-Na stimulation. The mRNA and protein expression of TGF-beta1, CTGF, PAI-1 and TIMP-1 of HKC was significantly upregulated by AA-Na (P < 0.05). The above-mentioned enhanced mRNA and protein expression, except for PAI-1, was significantly downregulated by the medicinal serum of Yi-shen Ruan-jian san, compared with the control (normal rat serum in the same concentration) (P < 0.05).

CONCLUSIONThe fibrogenic effects of HKC activated by AA are antagonized by Yi-shen Ruan-jian san, through downregulating the expression of promoting excellular matrix (ECM) synthesis factors (TGF-beta1, CTGF) and inhibiting ECM degradation factor (TIMP-1).
