ABSTRACT
Massive open online courses (MOOC) is an emerging teaching mode based on website, which has been developed rapidly in China since 2013. Contemporary medical education, assisted by MOOC, diverges greatly with various modes. In this paper, the current situation and advantages of MOOC on medical education in the information age were analyzed, and suggestions for improvement of MOOC on modern medical education were proposed in combination with foreign case study, which is conducive to the reform and innovation of medical education model.
ABSTRACT
Objective To explore the establishment of a two-way referral system for the treatment of cervical diseases within a medical alliance. The two-way referral system was introduced to reduce the morbidity and mortality of cervical cancer through better management of patients'who have tested positive for cervical disease, screening effectively for early diagnosis and treatment of cervical precancerous lesions, and providing early interventions for cervical cancer patients. Methods The control group consisted of 2, 515 patients who had screened positive for cervical disease between January 2018 and December 2018 at one of four community health service centers that were not within the medical alliance. The experimental group consisted of 2, 384 patients who had screened positive for cervical disease at one of four community health service centers in the medical alliance. The control group was treated using the original management mode;the experimental group's treatment was managed within the two-way referral system, which included standardized screening, referral, follow-up, health education, and professional training. The hospital visit rates, time intervals from diagnosis to the start of interventions, detection rates, and treatment rates were observed for both groups of women. Results The hospital visit rates, detection rates, and treatment rates were higher for those in the experimental group than the control group. The time interval from receiving a diagnosis to the first hospital visit was (16.9±11.5) days for patients in the experimental group and (25.7±20.9)days for those in the control group. The difference was a statistically significant (-0.05). Conclusion The management of cases in a two-way referral system within a medical alliance facilitates patients receiving earlier diagnosis and treatment for cervical pre-cancerous lesions and malignant tumors. Such efficiency improvements may reduce morbidity and mortality as well as help control medical costs, all of which have long-term economic and social significance.
ABSTRACT
Objective:To detect the expression of tumor necrosis factor alpha in (TNF alpha) breast cacner and its relationship with imaging features.Methods:Using immunofluorescence and flow cytometry to detect the expression of TNF-α in MDA-MB-231 and MCF-7.Collect 82 patients with mammary gland disease,which was confirmed by pathological tissue,its pathological data,imaging data,and by immunohistochemistry to detect the expression of TNF-α in breast tissues,and analyze and the relationship between its expression and the pathological features and imaging characteristics.Results:TNF-α high expression in MDA-MB-231,the expression of TNF-oα in malignant breast tumor tissue significantly higher than that in benign tumor,the expression quantity associated with lymph node metastasis,TNM stages,strengthen uniform in MRI,the boundary and the shape of the X-ray Mammography (P=0.01),and color flow signal strength in ultrasound (P＜0.05).Conclusions:TNF alpha in breast tumor tissue was unusually high expression,and is closely related to some of the imaging features of breast tumor.
ABSTRACT
A scheme for constructing the information commons with characteristics of medical and pharmaceutical colleges and universities was put forward in term of its construction model, function layout and implementation steps in combination with the practical conditions in Library of Guangdong Pharmaceutical College according to the ques-tionnaire investigation and analysis of the suggestions proposed by the readers for the construction of information commons.
ABSTRACT
Objective To study the expression of tumor necrosis factor -α (TNF-a) and correlation with TNF-a in breast cancer. Methods We used SABC method to detect the expression of TNF-a in 112 cases of primary breast cancer, and analysis the relationship between TNF-α with histologic grades and ER. Results The positive expression rate of TNF-α in breast cancer was higher than those of normal tissues and lobular hyperplasia of the breast (X2 =8.573, P =0.014). There was no significant correlation between histologic grades and TNF-α (X2 =1.304, P =0.521). TNF-a had a positive correlation with ER in breast cancer (X2=11.949, P =0.001). Conclusion The positive expression rate of TNF-α in breast cancer was higher than those of normal tissues and lobular hyperplasia of the breast.TNF-α had a positive correlation with ER in breast cancer, but the exact mechanism is unclear.
ABSTRACT
Objective To determine the expression of Human Epidermal Growth Factor Receptor 2 (HER-2) in breast cancer and its correlation with Tumor Necrosis Factor-α (TNF-α). Methods We used SABC method to detect the expression of HER-2 and TNF-α in 112 cases of primary breast cancer, and analyzed the association of HER-2 expression with clinicopathological features and TNF-α expression. Results The positive expression rate of HER-2 in breast cancer was 35.71% (40/112), of which, the expression rate was 35.05% (34/97) in 97 invasive tubic breast cancer, and 33.33% (2/6) in invasive lobular breast cancer,25.00% (1/4) in mucinous carcinoma, and 50. 00% (2/4) in intraductal carcinoma. There was no significant correlation between HER-2 and any clinicopathological features of primary breast cancer ( P ＞ 0. 05 ). The expression of HER-2 in breast cancer had no signiciant association with TNM stage, age, age of menarche,menopause, gravidity, parity and family history of cancer ( Ps ＞ 0. 05 ), The positive rate of TNF-α was 23.61% (17/72) when HER-2 was negative, whereas the positive rate of TNF-α was 52. 50% (21/40) when HER-2 was positive. The expression of HER-2 was signiciantly positively correlated with the expression of TNF-α (r = 0. 881, P ＜ 0. 05 ). Conclusion HER-2 expression had a positive correlation with TNF-α in breast cancer,but the specific mechanism is still unclear.
