ObjectiveTo observe the effects of the water extracts of Trichosanthis Radix-Polygonati Rhizoma at different ratios on glucose and lipid metabolism in KKAy mice with spontaneous type 2 diabetes and explore the mechanism of the extract in alleviating insulin resistance based on phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/forkhead box O1 （FoxO1） signaling pathway. MethodThe 8-week-old C57BL/6J male mice were taken as the normal control group， and KKAy male mice of the same age were randomly assigned into a model group， a metformin group， Trichosanthis Radix-Polygonati Rhizoma groups at the ratios of 1∶1 （Trichosanthis Radix 30 g， Polygonati Rhizoma 30 g）， 1∶3 （Trichosanthis Radix 15 g， Polygonati Rhizoma 45 g）， and 1∶5 （Trichosanthis Radix 10 g， Polygonati Rhizoma 50 g） according to blood glucose level and body weight， with 6 mice in each group. The administration lasted for 8 weeks， and the body weight （BW） and fasting blood glucose （FBG） of mice were recorded at the same time points of the 2nd， 4th， 6th， and 8th weeks， respectively. Oral glucose tolerance test （OGTT） was performed at the 7th week. After drug administration， the serum levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， and fasting insulin （FINS） were measured， and homeostasis model assessment-insulin resistance （HOMA-IR） index was calculated. The liver tissue samples were stained with hematylin-eosin （HE） and periodic acid-Schiff （PAS） for observation of the fat distribution and glycogen content. The protein levels of PI3K， Akt， p-Akt， FoxO1， and p-FoxO1 in the liver were determined by Western blot. ResultCompared with the normal group， the model group showed increased food intake， FBG， glucose tolerance， FINS， HOMA-IR， TC， TG， and LDL-C （P<0.01）， and down-regulated protein levels of PI3K， Akt， phosphorylaison （p）-Akt， FoxO1， and p-FoxO1 in the liver （P<0.01）. Compared with the model group， Trichosanthis Radix-Polygonati Rhizoma lowered FBG and HOMA-IR （P<0.05， P<0.01）. In particular， the combination at the ratio of 1∶3 showed the best performance （P<0.01） comparable to metformin. Furthermore， Trichosanthis Radix-Polygonati Rhizoma at different ratios lowered blood glucose at different time points of OGTT （P<0.05） and TC and LDL-C （P<0.01）. Additionally， the combination at the ratio of 1∶3 reduced TG （P<0.01）. The liver of mice in the drug administration groups showed regular morphology， with few lipid droplets and rich glycogen. Western blot showed that Trichosanthis Radix-Polygonati Rhizoma up-regulated the protein levels of PI3K and p-Akt， down-regulated the protein level of FoxO1， and up-regulated the protein level of p-FoxO1 （P<0.05）. ConclusionTrichosanthis Radix-Polygonati Rhizoma， especially at the ratio of 1∶3， lowered the FBG， TC， LDL-C， and HOMA-IR index， promoted liver glycogen synthesis， and reduced steatosis in KKAy mice， which may be related to the regulation of PI3K/Akt/FoxO1 signaling pathway in the liver.

Research progress of brain injuries in patients with small cell lung cancer caused by prophylactic cranial irradiation / 国际肿瘤学杂志

Small cell lung cancer (SCLC), as a pathological type with high malignancy, presents a high risk of early brain metastasis. Prophylactic cranial irradiation (PCI) can reduce the risk of brain metastasis in patients with SCLC, however, the incidence of brain structural and functional damage caused by PCI is high, and their clinical symptoms are not typical. The existing treatment methods can relieve some clinical symptoms, but can not effectively reverse the process of brain injury, which reduces the survival benefit of patients. In-depth understanding the mechanisms of PCI neurotoxicity and exploring effective strategies for ptevention and treatment are of great value in improving prognosis of SCLC.

Methods A total of 120 female BALB/c mice were randomly and equally divided into Ei, En, Ci and Cn groups. Three days before vaginal inoculation, estrogen (Ei and En)groups and control(Ci and Cn)groups received subcutaneous injection of 0.05 mg estradiol and 0.1 ml sterilized soybean oil at the hind legs, respectively, and then the hormone treatment continued every other day until the end of experiment. Infected(Ei and Ci)groups and noninfected(En and Cn) groups were inoculated intravaginally with 10μl(5 × 104 conidia)of Candida albicans suspension and 10μl of sterilized phosphate?buffered saline, respectively. Ten mice were randomly selected from each group and sacrificed on day 3, 7 and 14 after inoculation. The intact vagina tissues were resected and then frozen in liquid nitrogen or embedded in paraffin. Real?time fluorescence?based quantitative PCR(qRT?PCR)and immunofluorescent staining were performed to measure mRNA expression and immunofluorescence intensities of retinoic acid?related orphan receptorγt(RORγt), RORα and IL?17, respectively. Western blot analysis was conducted to determine protein expression of RORγt and IL?17. Results Laser scanning confocal microscopy showed that RORγt, RORα and IL?17 immunofluorescence was mainly located at inflammatory cells of the lamina propria and blood vessels in En and Cn groups, at mucosal epithelium, adherent hyphae, and inflammatory cells of the lamina propria and blood vessels in Ci group, and at mucosal epithelium, vaginal canal and endocytosed hyphae, and inflammatory cells of the lamina propria and blood vessels in Ei group. qRT?PCR and immunofluorescent staining uncovered that mRNA expression and immunofluorescence intensities of RORγt, RORα and IL?17 were significantly higher in En, Ci and Ei groups than in Cn group at the same time points(all P0.05). Moreover, RORγt and IL?17 protein expression in Ci and Ei groups was obviously up?regulated on day 7 after inoculation (RORγt: F = 13.137, P < 0.001; IL?17: F = 11.182, P < 0.001), but was not increased further on day 14. Conclusion Vaginal candida infection can up?regulate the expression of RORγt, RORα and IL?17, suggesting that Th17/IL?17 axis may be involved in the occurrence of vaginal candidiasis in BALB/c mice.
