Objective To investigate the imaging diagnosis of acetabular dysplastic coxarthrosis. Method The imaging of the acetabular dysplasia was analyzed in 51 patients (87 hips). All but four patients were women. The age ranged from 22 to 78 years, and the mean age was 42.6 years. Pelvis radiographs were studied in all cases, and CT scan was performed in 18 cases and MRI in 10 cases. Results The fundamental signs on the plain film included shallow acetabulum, increased obliquity and insufficient coverage of the femoral head by the acetabulum. The CE angles were determined in all the cases, ranging from -10? to 30?, mean 12.9?. The charp angles ranged from 35? to 67?, mean 45.3?. The secondary osteoarthritis were revealed in 75 hips (84.2%). 54 hips (62.1%) had cyst like lesions in weight bear area of the acetabulum or femoral head. 19 hips had subluxation of femoral head. CT and MRI displayed small cystlike lesions and forward shift of the femoral head, which could not be shown on plain film, respectivly in 13 and 10 hips. Conclusion The cyst like lesion of subarticular region is a common sign in acetabular dysplastic coxarthrosis. CT or MRI can show the early osteolytic lesion and forward subluxations.

Organoids are in vitro three-dimensional(3D)multicellular cultures that are generated through deploying the self-renewal and self-organizing capacities of stem cells.They recapitulate key structural and functional features of corresponding organs or tissues,providing an ideal in vitro model and research platform for the study of developmental biology,regenerative medicine,disease modeling and drug development.The conventional organoid culture system mainly relies on manual operations with lengthy and complicated procedures,which generate organoid cultures of individual variations and batch differences,limiting their translational applications.Therefore,to engineer the organoid culture system by introducing microfluidic chip technology to enhance the throughput and automation level,is of great significance for achieving large-scale,homogeneous,and standardized organoid cultures.This article reviews the current research progress of high-throughput and automated organoid chips and discusses the main limitations and potential challenges for the future study.

DNA damage repair (DDR) system plays an important role in maintaining of genomic stability. Accumulation of DNA lesions or deficiency of DDR system could drive tumorigenesis as well as promote tumor progression; meanwhile, they could also provide therapeutic opportunities and targets. Of all the antineoplastic agents of lung cancers, many of them targeted or were associated with DNA damage and repair pathways, such as chemotherapies and antibody-drug conjugates which were designed directly causing DNA damages, targeted drugs inhibiting DNA repair pathways, and immune-checkpoint inhibitors. In this review, we described the role of DNA damage and repair pathways in antitumor activity of the above agents, as well as summarized the application and clinical investigations of these antineoplastic agents in lung cancers, in order to provide more information for exploring precision and effective strategies for the treatment of lung cancer based on the mechanism of DNA damage and repair.

With the development of sequencing technology, the detection rate of non-small cell lung cancer (NSCLC) with primary epidermal growth factor receptor (EGFR) T790M mutation is increasing. However, the first-line treatment for primary EGFR T790M-mutated NSCLC still lacks standard recommendations. Here, we reported three advanced NSCLC cases with EGFR-activating mutation and primary T790M mutation. The patients were initially treated with Aumolertinib combination with Bevacizumab; among which, one case was discontinued Bevacizumab due to bleeding risk after treatment for three months. Treatment was switched to Osimertinib after ten months of treatment. Another case switched to Osimertinib and discontinued Bevacizumab after thirteen months of treatment. The best effect response in all three cases was partial response (PR) after initial treatment. Two cases progressed after first-line treatment and progression-free survival (PFS) was eleven months and seven months respectively. The other one patient had persistent response after treatment, and the treatment duration has reached nineteen months. Two cases had multiple brain metastases before administration and the best response to intracranial lesions was PR. The intracranial PFS was fourteen months and not reached (16+ months), respectively. There were no new adverse events (AEs), and no AEs of grade three or above were reported. In addition, we summarized the research progress of Osimertinib in the treatment of NSCLC with primary EGFR T790M mutation. In conclusion, Aumolertinib combined with Bevacizumab in the treatment of advanced NSCLC with primary EGFR T790M mutation has a high objective response rate (ORR) and control ability of intracranial lesions, which can be used as one of the initial options for first-line advanced NSCLC with primary EGFR T790M mutation.

BACKGROUND:
Malignant pleural effusion (MPE) refers to pleural effusion which arises from primary malignant tumor of pleura or other pleural metastatic tumors. Injection of elemene in chest makes good effect on the treatment of MPE, and is widely used in clinic. Adverse effects also exist, but the severe adverse effects and relevant managements are rarely reported. The aim of this study is to observe the adverse reactions induced by the treatment of malignant pleural effusion through elemene injection and to explore the solutions.
METHODS:
A retrospective analysis was made on 14 cases of patients receiving intra-pleural injections with elemene, and the incidence of severe adverse reactions of 7 cases were disscussed in detail.
RESULTS:
Most of the severe adverse reactions caused by elemene were severe chest pain, dyspnea, wheezing, clouding of consciousness and coagulopathy.
CONCLUSIONS
Strict screening, full preprocessing and close monitoring are necessary to prevent serious adverse reactions caused by elemene injection in the treatment of malignant pleural effusion.

Tyrosine kinase inhibitor (TKI) have been proved to be effective in the treatment of advanced non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) sensitive mutation, which is superior to chemotherapy. However, there are still some patients with sensitive mutations have primary drug resistance. It may be related to the coexistence of susceptible and resistant mutations of EGFR gene, downstream mutations of EGFR pathway, MET amplification and BIM deletion polymorphism. We present 2 cases of primary drug resistance and analyze the reasons.

Immune checkpoint inhibitors (ICIs) have become an important means of cancer treatment, and their application in the clinic is becoming more and more widespread. The adverse reactions caused by ICIs are gradually recognized. Among them, immunotherapy-related diabetes is a rare adverse reaction and type 1 diabetes mellitusis common. With the wide application of ICIs combined with chemotherapy in lung cancer patients, patients with type 2 diabetes mellitus have gradually been discovered during the treatment. However, the effect of continued use of ICIs maintenance therapy on blood glucose and ICIs treatment process in these patients is still unclear. This article reports two cases of type 2 diabetes mellitus induced by immune checkpoint inhibitor combined with chemotherapy, one of whom converted to type 1 diabetes mellitus, in order to increase the understanding of immunotherapy-related diabetes.

BACKGROUND:
Chemotherapy is the most important method for cancer treatment. However, chemotherapy induced nausea and vomiting (CINV) has a profound effect on patients. In recent years, there have been new antiemetic drugs, such as aprepitant. We review the curative effect of aprepitant with tropisetron and dexamethasone for prevention of nausea and vomiting in patients receiving Cisplatin chemotherapy.
METHODS:
Observation is divided into three stages. Whole study phase (0-120 h after chemotherapy administration), acute phases (0-24 h), and delayed phase (24 h-120 h). The primary endpoints were complete response (CR) and complete prevention (CP) during the three different study phase.
RESULTS:
In the whole study phase, 86.02% of patients achieved CR; in acute phases and delayed phases were 89.25%, 87.1%, respectively. CP were 46.22%, 83.87%, 45.16%, respectively. Anti-CINV effect was significantly associated with age distribution (P=0.008).
CONCLUSIONS
Aprepitant with tropisetron and dexamethasone prevented effectively CNIV for patients receiving Cisplatin chemotherapy. This combination could improve the quality of life and the compliance of patient with chemotherapy.
