In the past 30 years, dengue has undergone dramatic changes in China every year. This study explores the epidemiological trend of dengue in China during this period to identify high-risk seasons, regions, ages, susceptible populations, and provide information for dengue prevention and control activities. Dengue data from 1990 to 2019 were derived from the Public Health Science Data Center, Web of Science, China National Knowledge Infrastructure, PubMed, and Centers for Disease Control and Prevention of the corresponding province. ⋯ The endemic areas were Guangdong, Guangxi, Yunnan, Fujian, and Zhejiang provinces. People aged 25 to 44 years, men, students, business service staffs, workers, farmers, retired staffs, housewives, and the unemployed were more susceptible to dengue fever. These findings help to develop targeted public health prevention and control measures.

"Sclerotic Band" type of classification system and measurement of necrotic area for osteonecrosis of the femoral head.
Osteonecrosis of the femoral head is a common orthopedic disease. Based on years of clinical experience and significant imaging data, this study aimed to elucidate a new type of it, to help improve prognosis in young adults and provide a basis for hip preservation treatment. From January 2014 to December 2016, a total of 211 patients undergoing hip preservation surgery for femoral head necrosis at our hospital were enrolled in this study. ⋯ After analysis, it is more accurate than JIC. The "Sclerotic band" type of classification system and 'quartile' methods are new methods to evaluate the stability of femoral head necrosis. They are convenient for clinical application and easily adopted.

Feasibility of neoadjuvant and adjuvant intraperitoneal chemotherapy in patients with advanced epithelial ovarian cancer: A single-center experience.
Intraperitoneal (IP) chemotherapy is believed to prolong the survival of patients with advanced ovarian cancer after primary debulking surgery. However, there is little knowledge about IP chemotherapy in the setting of neoadjuvant chemotherapy, and there are contradictory conclusions about adjuvant IP chemotherapy. Here, we evaluated the feasibility of neoadjuvant and adjuvant IP chemotherapy in patients with advanced epithelial ovarian cancer (AEOC). ⋯ However, adjuvant IP cycles along with BMI were the determining factors for DFI in the R0 group (HR = 0.703, 95% CI = 0.525-0.941; HR = 1.130, 95% CI = 1.025-1.247), and were associated with OS in the R0 group (HR = 0.488, 95% CI = 0.289-0.824). The OS and DFI Kaplan-Meier curves stratified by adjuvant IP chemothearpy cycles within the R0 group were statistically significant (P = .024 and P = .033, respectively). Our results showed improvement in patients with AEOC in terms of survival, thus suggesting the feasibility of neoadjuvant and adjuvant IP chemotherapy.

Underlying factors relating to acute myocardial infarction for coronary artery ectasia patients.
Coronary artery ectasia (CAE) patients were more prone to present with acute myocardial infarction (AMI), this case-control research aimed to explore the underlying factors relating AMI for them. This study investigated a serial of 119 patients who underwent coronary angiography and were diagnosed as CAE between the years 2016 and 2017 at the Beijing Friendship Hospital; 32 of the patients developed AMI and 87 did not develop AMI. ⋯ Logistic regression analysis also indicated that AMI history, lower antiplatelet rate, higher NL ratio, higher low-density lipoprotein cholesterol level and Gensini score, as well as Markis type II were associated with AMI in CAE patients. AMI history, lower antiplatelet treatment rates, poor blood lipid control and higher coronary stenosis extent, higher inflammatory response, and Markis type II were closely related to the incidence of AMI in CAE patients.

Glutathione S-transferase gene polymorphisms (GSTT1 and GSTM1) and risk of schizophrenia: A case-control study in Chinese Han population.
Schizophrenia (SCZ) is a chronic disability disorder related to oxidative stress. Glutathione S-transferase (GST) is a group enzyme that protects cells and tissues from oxidative stress damage. Among GSTs, GSTT1 and GSTM1 have well defined genetic polymorphisms. ⋯ We also found that the combination of null genotypes of the GSTT1 and GSTM1 genes was made at a lower risk of SCZ (OR = 0.452, 95% CI = 0.238-0.845, P = .028). However, we found no correction between Positive and Negative Syndrome Scale score (PANSS) and GSTM1, GSST1 genotypes in SCZ patients. Our finding revealed that GSTT1 null polymorphisms may be related to the reduced risk of SCZ in Chinese Han population, and this risk was further reduced with the combination of GSTT1 null polymorphisms and GSTM1 null polymorphisms.
