Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence rate and mortality worldwide. However, most patients are not suitable for radical treatment at the time of first diagnosis. As one of the important schemes for the treatment of HCC, one of the most representative drug is Sorafenib, which has certain survival benefits for HCC patients at different stages. However, the drug resistance of HCC to Sorafenib greatly limits its efficacy. So far, people have found that some natural substances, experimental agents and biological macromolecules can reverse the drug resistance of HCC to Sorafenib through tumor cell microenvironment, metabolism and other mechanisms. This article will summarize the above substances and their mechanism in order to provide research ideas for the improvement of Sorafenib′s treatment program.

This study investigated the expression and clinicopathological significance of CD9 in gastrointestinal stromal tumor (GIST). Immunohistochemistry staining for CD9 was performed on tumor tissues from 74 GIST patients. The correlation with clinicopathological features, risk classification and prognosis was analyzed. CD9-positive staining comprised 59.5% (44/74) of the GIST patients. The CD9-positive expression rate of the sample was significantly associated with diameter (P = 0.028), mitotic counts (P = 0.035), risk classification (P = 0.018) and three-year recurrence-free survival (RFS) (P < 0.001). Cox proportional hazards regression (HR = 0.352; P = 0.015) showed that CD9 is an independent factor for post-operative RFS. The subgroup analysis showed that CD9 expression in gastric stromal tumor (GST) is significantly associated with diameter (P = 0.031), risk classification (P = 0.023) and three-year RFS (P = 0.001). The Cox proportional hazards regression (HR = 0.104; P = 0.006) also showed that CD9 is an independent factor for RFS of GST. However, CD9 expression does not have a statistically significant correlation with clinicopathological features, risk classification, and prognosis in non-GST. In conclusion, CD9 expression in GIST appears to be associated with the recurrence and/or metastasis of GIST patients, especially in GST, which may indicate the important role of CD9 in the malignant biological behavior and prognosis of GST.

Hepatocellular carcinoma (HCC) is the sixth most common malignant disease in the world and one of the main causes of cancer-related death. At present, the treatment of patients with advanced HCC is very limited, and as an important research direction of advanced cancer treatment in recent years, immunotherapy has achieved good results. Up to now, scholars have tested a variety of immunotherapy methods, and the use of immune checkpoint inhibitor (ICIs) in the treatment of advanced cancer has made considerable progress. However, immunotherapy is still incurable for HCC, and the benefit of treatment is limited to a small number of patients. In the current context of liver cancer, one of the key research directions of oncology is to understand the biomarkers that predict the clinical response of immunotherapy, so as to improve patient selection, maximize clinical benefits and avoid unnecessary toxicity. Compared with tumor and surrounding tissue biomarkers, peripheral blood biomarkers play a unique role in clinical research and use because of their advantages of non-invasive detection. In this review, we summarize the peripheral blood biomarkers that play a key role in predicting the clinical response and prognosis of HCC patients.

Abstract: Objective　To understand the epidemiological characteristics of the migratory bird population with hypertension in Hainan and to provide a basis for the health management of the migratory bird population. Methods　One hundred and eighty migratory birds with hypertension who had lived in in the Mangrove Bay community of Chengmai, Hainan for 3 months or more were selected as the study population. Demographic data, including gender, age, ethnicity, occupation, medication use, family history of hypertension, hometown living environment, Hainan living environment (presence of water area and greenbelt around the residence, type of water area and greenbelt), smoking and alcohol consumption, and height and weight were collected by questionnaire and physical examination to investigate the epidemiological characteristics of the study subjects, and unconditional dichotomous logistic regression analysis was used to identify factors affecting the reduction of blood pressure among the hypertensive migratory bird population before and after taking medication in Hainan. Results　A total of 180 study subjects were included, including 77 (42.8%) males and 103 (57.2%) females, with 78 (43.3%) subjects aged ≤65. The hypertension levels were: 87 (48.3%) had normal high blood pressure, 56 (31.1%) had grade 1 hypertension and 37 (20.6%) had grade 2 hypertension. The higher the blood pressure classification, the lower the percentage of migratory individuals whose blood pressure dropped during their stay in Hainan. Age, hypertension classification, dietary habits, living environment, body mass index (BMI), and alcohol consumption were associated with a decrease in blood pressure during Hainan among the study participants who took hypertension medication regularly. Salty diet (OR=2.778, 95%CI:1.070-7.213, P=0.036) and alcohol consumption (OR=2.686, 95%CI:1.042-6.925, P=0.041) were unfavorable factors for lower diastolic blood pressure before taking medication; overweight (OR=3.487, 95%CI:1.306-9.310, P=0.013) was an unfavorable factor in the reduction of diastolic blood pressure after taking medication. Conclusion　The blood pressure reduction is more significant in migratory individuals in migratory individuals under 65 years old, with a light diet, no alcohol consumption and normal BMI. Environmental factors, age, dietary habits and lifestyle are the main causes of blood pressure, which can provide a reference basis for the health management of the migratory birds with hypertension in Hainan.
