Trastuzumab combined with chemotherapy improves overall response rate in women with HER2-overexpressing breast cancer.However,therapeutic resistance to trastuzumab typically occurs after several months of starting therapy and overall survival does not improve significantly.Studies have reported that the potential mechanisms of resistance to trastuzumab are mainly related to the signal pathway activation from receptor tyrosine protein kinases outside of the HER family and the amplification of the PI3K-AKT pathway.Novel target therapies such as tyrosine kinase inhibitors,PI3K inhibitors are approved as substitutes for the treatment of HER2-overexpressing breast cancer,but the response to each single-agent tends to be short-lived.Several large randomized adjuvant trials have showed that novel molecular targeted therapies combinations will markedly limit or eventually abrogate acquired resistance to primary trastuzumab therapy.

It is important to design and build a kinetic loading system for flexing movement of knee joint to study knee biomechanics. The system reported here includes driving device, control device, and flexion angle determination imaging system. The driving device was constructed with a stepper motor and a mechanical transmission with a serried of clamps, shanks and so on, and the driving device was controlled by the control device with micro-control unit, a computer and the serial 232. While the knee joint was driven to move by the stepper motor, the flexion angle of the knee was determined using imaging-based techniques. The system achieved accurate loading and control of speed, extent and duration of knee flexion, as well as fast and non-contract determination of flexion angle during knee flexing movement. The system is simple to build, easy to operate, highly accurate and reliable and it provides an important tool for the study of knee biomechanics, and potentially provides a tool for helping patients of knee surgery during their post operation recovery training.

Objective? To explore the quality of life in patients with cognitive disorder and to discuss its influencing factors so as to provide a reference for improving the quality of life in patients with cognitive disorder. Methods? Totally 1 398 neurological patients from a neuropsychiatric hospital in Nanjing were screened using cluster sampling and 125 patients with cognitive disorder were selected as subjects between January and December 2017. The subjects received a cross-sectional study with Quality of Life in Alzheimer＇s Disease (QOL-AD), Montreal Cognitive Assessment Scale (MoCA), Activities of Daily Living Scale (ADL), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and the general information questionnaire. Variance analysis, Pearson correlation analysis and multivariate linear regression analysis were used for statistical analysis. Results? The morbidity of cognitive disorder in neurological patients from our hospital was 9.3%. Their QOL-AD score was (31.88±6.54). Sex, educational background, nature of work, household income, sleep and bad social relations are factors affecting the quality of life of the subjects (P＜0.05). According to multivariate linear regression analysis, MoCA, SAS and SDS were main factors affecting the quality of life of the subjects (P＜0.05). Conclusions? Male patients with lower education, physical work and bad social relations are high-risk patients with lower quality of life. Cognitive disorder, anxiety and depression are main risk factors affecting the quality of life in patients with cognitive disorder. Nursing workers should improve and maintain the patients＇cognitive ability, enrich their cultural life and social activities, and enhance their mental health, thereby improving their quality of life.

Objective:To explore the risk factors for depression in patients with cognitive impairment and construct a prediction model to preliminarily validate the predictive performance of the model, aiming to provide medical and nursing staff with a screening tool for high-risk groups.Methods:From January 2020 to December 2021, convenience sampling was used to select 1 130 patients with cognitive impairment admitted to the Affiliated Brain Hospital of Nanjing Medical University as the research subject. The research subjects were divided into a modeling group ( n=791) and a validation group ( n=339) at a ratio of 7∶3. The influencing factors of depression in patients with cognitive impairment were determined using binomial Logistic regression and a risk prediction model was established. The predictive performance of the prediction model was tested using the receiver operating characteristic (ROC) curve. Results:The incidence of depression in 1 130 patients with cognitive impairment was 51.3% (580/1 130). Binomial Logistic regression analysis showed that the influencing factors for depression in patients included age, Activities of Daily Living Scale score, Hamilton Anxiety Scale score, Pittsburgh Sleep Quality Index score, and Lewy Body Composite Risk score ( P<0.05). In the modeling group, the area under the ROC curve was 0.921, the Youden index was 0.716, the sensitivity was 0.834, the specificity was 0.882, and the prediction accuracy was 0.858. In the validation group, the area under the ROC curve was 0.896, the Youden index was 0.651, the sensitivity was 0.824, the specificity was 0.827, and the prediction accuracy was 0.825. Conclusions:The depression risk prediction model can effectively predict the risk of depression in patients with cognitive impairment, and can provide a screening tool for high-risk groups for medical and nursing staff.

Dyslipidemia is an important risk factor of atherosclerotic cardiovascular disease (ASCVD). Statins delay the occurrence and development of ASCVD, and reduce the risk of cardiovascular events and death. Due to safety concerns, there exist insufficient use of lipid-lowering agents and a high withdrawal rate of the agents in the elderly. To promote the prevention and treatment of ASCVD, this expert consensus is issued and focuses on the management of dyslipidemia of Chinese elderly basing on the clinical evidence of the use of lipid-lowering drugs by the elderly, and the lipid management guidelines and expert consensus recommendations at home and abroad.

To evaluate relationship of maternal hepatic vein Doppler flow parameters and cardiac output (CO) with neonatal birth weight in uncomplicated pregnancies (UP) and pregnancies complicated by fetal growth restriction (FGR) .
 Methods: Hepatic vein impedance index (HVI), venous pulse transit time (VPTT), and CO were measured in women with UP at the 14th-37th weeks and complicated by FGR at the 26th-37th weeks who underwent maternal hepatic hemodynamic and echocardiographic examination during the ultrasonography. After delivery, the birth weight and the birth weight percentile of each neonate in this study were recorded. Correlations among HVI, VPTT, and CO were analyzed.
 Results: In the UP group, HVI, VPTT, and CO changed with the increase of gestation. In the FGR group, HVI was higher, VPTT was shorter, CO and neonatal birth weight were obviously lower than those in the UP at the 26th-37th weeks (P<0.05).
 Conclusion: There is a series of adaptive changes in hepatic venous hemodynamics and CO in UP with the increase of gestation to meet the demand of fetal growth, while the maladaptive changes in hepatic venous hemodynamics and CO in pregnant woman may contribute to FGR.
