Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine (TCM). The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology, Western medicine obstetrics and gynecology, and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion, the experts concluded that chromosome, endocrine, and immune abnormalities were the key factors for the occurrence of threatened abortion, and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion, TCM has advantages in preventing miscarriages, alleviating clinical symptoms and TCM syndromes, relieving anxiety, regulating reproductive endocrine and immune abnormalities, personalized and diversified treatment, enhancing efficiency and reducing toxicity, and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

As an important tumor driver gene, epidermal growth factor receptor (EGFR) gene plays an important role in the development and progression of non-small cell lung cancer (NSCLC). As the latest generation of EGFR-tyrosine kinase inhibitor (TKI) drugs, osimertinib has brought significant therapeutic efficacies and encouraging results both in patients with sensitive EGFR mutations and patients with rare EGFR mutations. Compared with previous EGFR-TKI drugs, osimertinib has strong blood-brain barrier penetration, which can effectively prevent the occurrence of lung cancer brain metastasis. After the resistance of first and second generation of targeted drugs, osimertinib is still effective in the follow-up treatment process. This article reviews the characteristics of EGFR mutation, the action mechanism of osimertinib, and the latest progress of osimertinib in treatment of EGFR mutations in NSCLC.

Brain metastasis is a common complication of non-small cell lung cancer (NSCLC) patients. About 25%-55% of patients with NSCLC will develop brain metastases, and the occurrence of brain metastasis predicts a poor prognosis. Traditionally, radiotherapy, chemotherapy, targeted therapy and surgery are the main treatment options for NSCLC patients with brain metastases. In recent years, with the emergence of immune checkpoint inhibitors (ICI), the survival of NSCLC patients with brain metastases has been significantly improved. This article reviews the research progress of ICI treatment for NSCLC patients with brain metastases in order to provide new treatment strategies.

Malignant pleural mesothelioma (MPM) is a malignant tumor with strong invasiveness, low survival rate and lack of effective treatment options. As the only first-line treatment plan for the advanced MPM, combination of pemetrexed and cisplatin chemotherapy have been existing since the last 20 years. Immunotherapy has long been considered as a potential treatment plan for MPM, mainly including immune checkpoint inhibitors (ICIs), immunotoxin therapy, anti-cancer vaccine and adoptive T-cell therapy. This review focuses on summarizing the current research status of immune checkpoint inhibitors in MPM, discusses the effect of tumor heterogeneity on ICIs treatment, and describes that the biomarker-oriented immunotherapy is a new vision for the realization of individualized treatment of MPM. .

Pulmonary neuroendocrine tumors (PNETs) are a kind of epithelial tumors originating from pulmonary neuroendocrine cells, accounting for about 20% of primary lung tumors, including typical carcinoid, atypical carcinoid, small cell carcinoma, and large cell neuroendocrine carcinoma. The morphologic and clinical characteristics of these four types of PNETs are relatively highly heterogeneous. Immune checkpoint inhibitors (ICIs) have been shown robust antitumor activity in a variety of solid tumors. Treatment regimens of advanced PNETs have developed greatly in the past decade, but ICIs are still in their infancy in the field of PNETs. This review focuses on the landscape of current clinical trials and research as well as the situation of ICIs-related biomarkers in PNETs. .

Hyponatremia is the most common electrolyte abnormality in cancer patients, which is usually related to the syndromes of inappropriate antidiuretic hormone secretion (SIADH). Despite not frequent life-threatening, it mostly causes prolonged hospitalization, delaying in scheduled chemotherapy, reducing of the efficacy, worsening of patients' prognosis and quality of life. The optimal treatment strategy should be chosen based on the severity and the onset time of the symptoms in clinic. Hypertonic saline solution is appropriate for acute, symptomatic patients with hyponatremia caused by SIADH, nevertheless fluid restriction is advised to chronic symptomless hyponatremia which recommends correcting at a slower rate. When fluid restriction is limited, pharmacological therapy should be a necessary choice. This review summarizes the recent progress of hyponatremia in international guidelines and discusses the defect of hyponatremia managements and the research prospect in the future.
