Objective To study the apoptosis of human colorectal cancer HT-29 cells induced by Aralia elata Seem leaf total saponin (ETS) and its effects on the expression of relevant proteins. Methods MTT assay was used to detect the proliferation of human colorectal cancer HT-29 cells cultivated with different concentrations (6.25, 12.5, 25, 50, 100, 200 mg/kg) of ETS. Hoechst33258 staining and laser confocal imaging were used to detect the apoptotic cells. Morphological changes were observed. The expressions of Bcl-2 and Bax were detected by immuno-histochemistry. Results ETS could induce apoptosis of HT-29 cells and apoptosis was in a dose-dependent manner in a certain range. ETS could decrease the expression of Bcl-2 and increase the expression of Bax in HT-29 cells (P<0.05, P<0.01), showing a significant dose-effect relationship. Conclusion ETS can induce the apoptosis of HT-29 cells, and the mechanism may be related to reducing the expression of Bcl-2 and increasing the expression of Bax.

Objective:To analyze the global incidence and mortality of cancer from 1990 to 2019.Methods:The Global Burden of Disease Study 2019 (GBD2019) database was utilized to analyze the global incidence and mortality of cancer, the order of incidence and mortality of cancer, the incidence and mortality of different age groups, and the trend of incidence and mortality from 1990 to 2019. Standardized incidence and mortality rates were derived by utilizing the world standard population age structure.Results:In 1990, global cancer cases numbered 10.295 9 million with an incidence rate of 192.45/100 000, leading to 5.732 6 million deaths and a mortality rate of 107.16/100 000. While in 2019, global cancer cases escalated to 23.568 5 million with an incidence rate of 304.60/100 000, resulting in 10.022 8 million deaths and a mortality rate of 129.54/100 000, all higher than those in 1990. In 2019, lung cancer showed the highest incidence rate of both sexes combined in the world (29.21/100 000), followed by colorectal cancer, breast cancer, prostate cancer and gastric cancer. The incidence of lung cancer was highest among males (39.24/100 000), while the incidence of breast cancer was highest among females (51.27/100 000). Lung cancer also had the highest mortality rate worldwide in both sexes combined (26.40/100 000), followed by colorectal cancer, gastric cancer, breast cancer and pancreatic cancer. Lung cancer had the highest mortality among males (35.72/100 000), while breast cancer had the highest mortality among females (17.85/100 000). In 2019, the global cancer incidence rate showed an upward trend with age. The incidence rate was low before the age of 25, and increased rapidly after the age of 25. The incidence rates of both sexes combined, males and females all reached the peak in the age group of over 85 years old, which were 3 084.18/100 000, 4 434.81/100 000 and 2 353.07/100 000 respectively; The incidence rate of females in the age group of 20-50 years old was higher than that of males, but the incidence rate of males in the age group of over 55 years old was higher than that of females. Compared with 1990, the incidence rates of both sexes combined in the age group of over 20, of males over 55 years old, as well as of females over 15 years old, were all higher than those in 2019. In 2019, the global tumor mortality rate showed an upward trend with age. The mortality rate was relatively low before the age of 35, and increased rapidly after the age of 35. The mortality rates for both sexes combined, as well as for males and females, reached the peak in the age group of over 85 years old, which were 1 787.84/100 000, 2 509.87/100 000, and 1 369.99/100 000 respectively; The mortality rate of females in the age group of 20-40 years old was higher than that of males, and the mortality rate of males in the age group of over 45 years old was higher than that of females; For the age of 0-80 years old, the mortality rates for both sexes combined, males, and females were lower in 2019 than 1990, but higher in the age of 85 years old and above. The global standardized incidence rate of cancer showed an overall upward trend, with an average annual increase of 0.30% from 1990 to 2019. The global standardized mortality rate of cancer showed an overall downward trend, with an average annual decrease of 0.60% from 1990 to 2019.Conclusion:From 1990 to 2019, the global standardized incidence rate of cancers shows an overall upward trend, while the global standardized mortality rate of cancers has an overall downward trend, and the global incidence and mortality rate of cancers increases with age. The global burden of cancer disease is still heavy. Lung cancer is the cancer with the highest incidence and mortality rate in the world. The highest incidence rate is lung cancer among males, and breast cancer among females. Different countries or regions need to take corresponding cancer prevention and treatment strategies according to their actual conditions.

OBJECTIVE: To investigate whether the level of homocysteine in patients with postpartum depression is associated with depression index. METHODS: A total of 43 women with postpartum depression or with potential postpartum depression, who visited the psychological clinic of Maternal and Child Health Hospital of Hunan Province from June, 2012 to April, 2014, were enrolled in this study. They were evaluated by the Edinburgh Postnatal Depression Scale and Hamilton Depression Scale. Chinese Classification of Mental Disorder (the third edition) was used for their diagnosis. The depressive index was calculated by Edinburgh Postnatal Depression Scale, Hamilton Depression Scale, and clinical symptom scores, which was used to assess the level of depressive symptoms. The level of homocysteine in serum was detected by chemoluminescent method. Meanwhile, another 31 women, who visited the hospital without postpartum depression, were used as controls to compare with the 43 patients. RESULTS: The homocysteine level in the women with postpartum depression was significantly higher than that in the control group [(10.09 ± 3.59) μmol/L vs (8.57 ± 1.59) μmol/L, t=12.392, P=0.001]. The depression index was positively correlated with the level of homocysteine (r=0.231, P<0.05). CONCLUSION The level of serum homocysteine is associated with postpartum depression, suggesting that the level of serum homocysteine might be a risk biomarker for postpartum depression.
