Purpose To study clinical pathological significance of the expression of PTEN, p53 and epidermal growth factor receptor ( EGFR) in breast carcinoma and their correlation. Methods Immunohistochemical MaxVision method was used to detect the expres-sion of PTEN, p53, EGFR in 209 cases of infiltrating ductal carcinoma of breast and 40 cases of benign breast diseases. Results The over-expression rate of PTEN, p53 and EGFR protein in breast carcinoma was 57. 9%, 55. 0% and 38. 3% respectively, which was significantly different from those in benign breast diseases (P<0. 05). The expression of PTEN, p53 and EGFR in breast cancer was correlated with tumor size, histological grade, lymph node metastasis, ER status, PR status and molecular subtype (P<0. 05). There was an association between PTEN or p53 and TNM stage, PTEN or EGFR and HER-2 status. There was a negative correlation in the protein expression of PTEN vs EGFR or PTEN vs p53 (P<0. 01). There was a positive correlation between EGFR and p53 protein ex-pression (P=0. 000). The expression of PTEN or EGFR was correlated with the prognosis of breast cancer, but not independent prog-nostic factors. The survival rate of patients with PTEN- /p53 + /EGFR+ was lower than those with other combined expression of PTEN/p53/EGFR (P=0. 008). Conclusions Low or loss expression of PTEN, p53 mutation and EGFR over-expression may be coordinate-ly involved in the pathogenesis and progression of breast cancer. The combined detection of these markers may play an important role in making treatment and indicating prognosis for breast cancer patients.

A label-free electrochemical immunosensor using hollow structure nanomaterials based on its ordered porous and big surface area was designed. Au nanocage, with good conductivity, catalysis, and biocompatibility, was prepared and modified on the surface of glassy carbon electrode with graphene to immobilize antibody of microcystin directly. In the absence of microcystin, biosensor can obtain high current response signal of electrochemical probe ( [ Fe( CN) 6 ] 3-/4-. When microcystin was combined with its antibody specifically, the charge density and mass transfer resistance on the surface of electrode increased, resulting in a decrease of the corresponding peak current of [ Fe ( CN ) 6 ] 3-/4-. This change was in proportion to the concentration of microcystin indirectly. Experiment conditions such as cultivation time of antigen and concentration of antibody were optimized. The results showed wide linear range of 0. 05 μg/L-1. 0 mg/L and the detection limit of 0. 017 ng/mL. This sensor has good stability and simple production procedure. This sensor provides a new and simple means for the ultrasensitive determination of microcystins in real water samples.

Objective:To investigate the expressions of tissue inhibitor of matrix metalloproteinase-1 (TIMP1) and fibronectin 1 (FN1) in pregnancy associated breast cancer (PABC) and their correlations with expression of E-cadherin (E-cad).Methods:The clinicopathological data of 55 PABC patients in Binzhou People's Hospital Affiliated to Shandong First Medical University from January 2011 to December 2020 were retrospectively analyzed. Immunohistochemistry was used to detect expressions of TIMP1, FN1 and E-cad in cancer tissues and corresponding paracancerous tissues (>3 cm from the edge of the tumor foci). The expressions of TIMP1 and FN1 proteins in fresh intraoperative frozen cancer tissues and paracancerous tissues of 10 PABC patients were detected by Western blotting. The correlations of TIMP1 and FN1 expressions with clinicopathological characteristics of patients were analyzed by χ2 test, the correlation of TIMP1 and FN1 expressions with E-cad expression was analyzed by Spearman method, and the correlation of TIMP1 and FN1 expressions with survival was analyzed by Kaplan-Meier method. Results:The positive rates of TIMP1 and FN1 in PABC tissues were 72.7% (40/55) and 58.2% (32/55), and 25.5% (14/55) and 18.2% (10/55) in paracancerous tissues, and the differences were statistically significant ( χ2 values were 24.59 and 18.64, both P < 0.001). The results of Western blotting showed that the relative expressions of TIMP1 and FN1 proteins in the fresh cancer tissues of 10 PABC patients was higher than those in the corresponding paracancerous tissues (1.60±0.76 vs. 0.62±0.29, 1.31±0.62 vs. 0.44±0.15), and the differences were statistically significant ( t values were 5.92 and 4.86, both P < 0.001). The expressions of TIMP1 and FN1 in PABC tissues were correlated with estrogen receptor expression, Ki-67 positivity index, TNM stage and lymph node metastasis (all P < 0.05). The expressions of TIMP1 and FN1 were negatively correlated with expression of E-cad in PABC ( r values were -0.471 and -0.432, both P < 0.001). Five cases were lost to follow-up, and the remaining 50 cases had a median follow-up time of 43 months (12-90 months). Among the 50 cases, 36 cases were TMP1-positive and 29 cases were FN1-positive. The overall survival of TIMP1-negative group and FN1-negative group were better than those of the corresponding positive group ( χ2 values were 4.49 and 6.06, both P < 0.05); the median overall survival time of TIMP1-positive group and FN1-positive group were 51 months (95% CI 37-65 months) and 43 months (95% CI 32-53 months), while that of TIMP1-negative group and FN1-negative group were 89 months (95% CI 84-93 months) and 87 months (95% CI 85-92 months). Conclusions:TIMP1 and FN1 expressions are elevated in PABC tissues and negatively correlated with E-cad expression, TIMP1 and FN1 may be involved in PABC invasion through epithelial-mesenchymal transition and affect the prognosis of patients.

Background:
Most patients including health care workers (HCWs) survived the coronavirus disease 2019 (COVID-19), however, knowledge about the sequelae of COVID-19 after discharge remains limited.
Methods:
A prospectively observational 3-month follow-up study evaluated symptoms, dynamic changes of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) IgG and IgM, lung function, and high resolution computed tomography (HRCT) of survivors of COVID-19 after discharge at Wuhan Union Hospital, China.
Results:
Seventy-six survivors (55 females) with a mean age of 41.3 ± 13.8 years were enrolled, and 65 (86%) were HCWs. A total of 69 (91%) patients had returned to their original work at 3-months after discharge. Most of the survivors had symptoms including fever, sputum production, fatigue, diarrhea, dyspnea, cough, chest tightness on exertion and palpitations in the three months after discharge. The serum troponin-I levels during the acute illness showed high correlation with the symptom of fatigue after hospital discharge (r = 0.782; P = 0.008) and lymphopenia was correlated with the symptoms of chest tightness and palpitations on exertion of patients after hospital discharge (r = −0.285, P = 0.027; r = −0.363, P = 0.004, respectively). The mean values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, total lung capacity and diffusion capacity were all normal (> 80% predicted) and lung HRCTs returned to normal in most of the patients (82%), however, 42% of survivors had mild pulmonary function abnormalities at 3-months after discharge. SARS-CoV-2 IgG turned negative in 11% (6 of 57 patients), 8% (4 of 52 patients) and 13% (7 of 55 patients), and SARS-CoV-2 IgM turned negative in 72% (41 of 57 patients), 85% (44 of 52 patients) and 87% (48 of 55 patients) at 1-month, 2-months and 3-months after discharge, respectively.
Conclusion
Infection by SARS-CoV-2 caused some mild impairments of survivors within the first three months of their discharge and the duration of SARS-CoV-2 antibody was limited, which indicates the necessity of long-term follow-up of survivors of COVID-19.

OBJECTIVE:
To investigate clinicopathological and prognostic significance of epithelial cell adhesion molecule (EpCAM) expression in breast cancer and its molecular subtypes.
METHODS:
The expression of EpCAM in 835 patients with breast invasive ductal carcinoma was detected by immunohistochemical Max VisionTM method, and its correlation with clinical pathological features and prognosis was analyzed.
RESULTS:
The positive expression of EpCAM was related to histological grade, lymph node metastasis, tumor size, clinical stage, the expression of estrogen receptor (ER), progesterone receptor (PR) and HER2 (P<0.05). The positive expression rates of EpCAM were 19.2%, 73%, 48.9%, 72.2%, and 62.1%, in Luminal A, Luminal B (HER2-), Luminal B(HER2+), HER2+, and triple-negative subtype, respectively. Log-rank test and univariate COX analysis showed that the EpCAM expression was associated with a poor prognosis in all patients (P<0.001), as well as the triple-negative subtype, luminal B subtype (HER2-), and HER2+ subtype (P<0.05). Multivariate COX analysis showed that EpCAM expression was associated with the survival in patients with the triple-negative or HER2+ subtype (P<0.05).
CONCLUSION
EpCAM may be associated with progress of breast cancer. It is an independent prognostic factor in breast cancer, especially in the triple-negative and HER2+ subtypes.
