Chemoimmunotherapy as induction treatment in concurrent chemoradiotherapy for patients with nasopharyngeal carcinoma stage IVa.

Background: Chemoimmunotherapy is the first-line therapy for patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) and is currently the main induction treatment option for patients with locoregionally advanced NPC. However, it remains unclear whether combining immunotherapy with standard induction chemotherapy enhances its efficacy. This study aimed to evaluate the efficacy, toxicity, and survival outcomes of induction chemoimmunotherapy in patients with locoregionally advanced NPC.

Complete mitochondrial genome of the planthopper (Germar, 1830) (Hemiptera: Fulgoromorpha: Dictyopharidae).

The first complete mitochondrial genome of a dictyopharid planthopper, (Germar, 1830) (Hemiptera: Fulgoroidea: Dictyopharidae) is sequenced. The 15,349 bp long complete mitogenome contains 13 protein-coding genes (PCGs), 22 genes, two rRNA genes, and 1 A + T-rich region with an arrangement identical to that observed in most insect mitogenomes (GenBankNo. MW441850).

[Effects of different soil types on the foliar δ13C values of common local plant species in karst rocky desertification area in central Guizhou Province].

By measuring the foliar δ13C values of common local plant species grown in different soil types in Wangjiazhai catchments, a typical karst desertification area in Qingzhen City, Central Guizhou, we studied the impact of soil type and rocky desertification grade on the foliar δ13C values. The results showed that the foliar δ13C values were more negative in yellow soil area than those in black calcareous area and there was no obvious difference in foliar δ13C values between these two soil types. The distribution interval of foliar δ13C values in yellow soil area was narrower than those in black calcareous area and the variation coefficient of foliar δ13C values in yellow soil area were smaller than those in black calcareous area.
