Microglial cells are the resident immune cells of brain. The activated microglia produces a range of deleterious substances, which plays an important role in the inflammation of post-stroke, such as superoxide, nitric oxide, matrix metalloproteinases, etc. The activa-tion of microglia may involve triggering receptor expressed on myeloid cells-1, Toll-like receptors 4, peroxisome proliferator-activated re-ceptors, purinergic receptors, etc. Intervention targeted to microglial receptor is becoming a new strategy for ischemic stroke.

Autophagy plays an important role in the regulation of activation and inflammation of microglia after ischemic stroke. The interaction between autophagy of microglia and the inflammation mediated by microglia after ischemic stroke was complex and a large num-ber of molecules were involved. The receptors of microglia activation and related substances may be possible mechanism in the regulation of microglia autophagy. Autophagy inhibitors and microglia receptor targeting therapy may provide new strategies for the clinical treatment of ischemic stroke. This paper summarized the progress of microglia autophagy after ischemic stroke.

Three kinds of fortified biscuits and bread were given as breakfast for 5 months to 106 preschool children 4-6 years old lodged in a kindergarten, with a control group taking common biscuits and bread without fortification. 6 g protein and 160 kcal were supplied by 50 g of fortifed foods in which 0.25 g lysine, 0.25 g lysine and 0.8 mg riboflavin, and cod liver oil and calcium in addition to lysine and riboflavin were fortified respectively. The results showed that a diet with intake of 2.1 g protein and 71 kcal/kg body weight fortified on the average by 228 mg lysine or 228 mg lysine and 1.1 mg riboflavin increased the monthly increment of body weights, heights, and urinary excretions of creatinine per day. There was also a tendency of improvement, in nitrogen retention. The urinary excretion of riboflavin in load test was increased in the group taking the second kind of fortified foods.

Objective To explore the protective mechanism of HSP70 protein in traumatic brain injury (TBI)‐related acute gastric mucosal lesions in mice .Methods Forty adult male Balb/c mice were randomly divided into sham (A) ,TBI (B) ,TBI+ geranylgeranylacetone (GGA) (C) ,and TBI+saline (D) groups .TBI was induced via the Feeney impact model .GGA (800 mg/kg) was administered via oral tube beginning before the model was built in group C .The expressions of HSP70 protein in brain and gastric mucosa were determined by immunohistochemistry , and the apoptotic index was detected by TUNEL method .Results The injury area in mouse brain and gastric mucosa was greater in group B than in groups A and C (P<0 .05) .After model induction ,the content of HSP70 protein in group B was markedly higher in the brain and gastric mucosa ,which was notably higher than in group A (P<0 .05) .Obviously apoptotic cells were observed in groups B and D ,which were significantly higher than in groups A and C .GGA pretreatment enhanced the up‐regulated expression of HSP70 and decreased the apoptotic index distinctly ;HSP70 expression was higher in group C than in groups B and D ,but the apoptotic index was lower (P<0 .05) .Conclusion GGA can induce HSP70 protein expression in mouse brain and gastric mucosa .HSP70 is involved in the process of apoptosis inhibition .GGA can be used in the prevention and therapy of TBI‐related acute gastic mucosal lesions .

Objective To analyze the role of preoperative peripheral blood inflammatory parameters and postoperative lymph-node ratio (LNR) in the prognosis of gastric cancer patients treated with chemotherapy. Methods The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammatory response index (SII), lymphocyte-to-monocyte ratio (LMR), Onodera prognostic nutritional index (OPNI), and LNR of 108 patients with gastric cancer were classified into high and low groups to analyze their prognostic value on the overall survival (OS) of gastric cancer patients treated with chemotherapy. The independent prognostic indicators were plotted in columns to predict the survival rate of gastric cancer patients. Results NLR was statistically significant in the prognostic assessment of gastric cancer patients treated with chemotherapy (
