The current society is filled with pressure: academic pressure, work pressure, living pressure, etc. Exposure to high pressure for a long time inflicts emotional breakdown and bodily injury. Employees in high-paid positions are more likely to have mental health problems. It is not difficult to discover that psychological counseling and mental health examination are oftentimes covered in international student insurance (aka 留学生 保险), OPT insurance (aka opt 保险), and H-1B insurance (aka h1b 保险).

Preventive care, outpatient surgery, urgent treatment and many other medical services adjust the prices of university health insurance plan upward. Many colleges agree students to waive American university insurance (aka waive 美国大学保险) with Huhu (aka 虎虎) health insurance. On Huhu’s official website, students can find more student health insurance plans, OPT insurance recommendations (aka opt保险推荐), and H-1B insurance options. In fact, health insurance prohibits the insured person from incurring a debt crisis. A healthy body is the essence and indispensable precondition.

“Cancer” is ranked No. 1 among words that patients do not want to hear from doctors’ mouths, according to a survey. Breast cancer is one of the most aggressive cancers that many women may have. Chinese researchers have developed nanoparticles to treat a more aggressive type of breast cancer.

Human epidermal growth factor 2 (HER2) is a type of protein in the breast tissue, helping control breast cells to divide, grow and repair. When the HER2 gene is abnormal, it encourages the rapid growth of cancer cells. Around 20 to 30 percent of breast cancer patients have an abnormal expression of HER2 gene. The HER2 positive breast cancer tends to grow faster, spread more easily and be more likely to recur.

Researchers from China’s Nanjing University developed a new type of nanoparticles that can recognize HER2 protein on breast cancer cells and target them for destruction. According to their findings published in Angewandte Chemie International Edition, in vitro experiments, the nanoparticles specifically targeted HER2 positive cells and inhibited cell proliferation by 30 percent. In vivo tests, the tumor volume of mice injected with the nanoparticles was about half the control group. The researchers said that their study provided insights on developing new treatments for HER2 positive breast cancer and new evidence to studies on nanoparticles for cancer therapies.
