Endoplasmic reticulum plays a key role in both basic structure formation and function performance of microenviron-ment. Endoplasmic reticulum homeostasis unbalance caused by endoplasmic reticulum stress has become a hot research topic in recent years. This paper focuses on the role of endoplasmic retic-ulum stress in ischemic stroke. Research progress of related sig-naling pathways were reviewed, especially mechanisms through which endoplasmic reticulum stress trigger the inflammatory reac-tion, so as to provide a new research method for prevention of is-chemic stroke.

Objective:To explore risk factors of in-stent restenosis (ISR) after vertebral artery stenting (VAS) in patients with ischemic cerebrovascular disease.Methods:Case-control studies and cohort studies on risk factors for ISR after VAS in patients with ischemic cerebrovascular disease were searched from CNKI, VIP, Wanfang, Chinese Biomedical literature Database, PubMed, Embase and Cochrane Library. The retrieval time limit was the establishment of each database until May 31, 2021. Two researchers screened the literature and extracted relevant data. Newcastle-Ottawa Scale (NOS) was used to evaluate quality of the literature and RevMan 5.3 software was used for meta-analysis.Results:A total of 30 studies were included. Meta-analysis results showed that smoking [ OR=3.76, 95% confidence interval ( CI) : 2.43-5.82, P<0.01], diabetes ( OR=2.95, 95% CI: 2.15-4.06, P<0.01) , hypertension ( OR=2.55, 95% CI: 1.50-4.34, P=0.006) , hyperlipidemia ( OR=7.12, 95% CI: 3.46-14.68, P<0.01) , coronary heart disease ( OR=3.06, 95% CI: 1.10-8.47, P=0.03) , homocysteine ( OR=2.36, 95% CI: 1.30-4.27, P=0.005) , clopidogrel drug-related gene ( CYP2C19) mutation ( OR=3.04, 95% CI: 1.63-5.68, P=0.005) , lesion vessel diameter ( OR=3.43, 95% CI: 1.30-9.05, P=0.01) , residual stenosis ( OR=6.08, 95% CI: 3.28-14.07, P<0.01) ) , stent type ( OR=2.26, 95% CI: 1.18-4.36, P=0.01) , stent length ( OR=3.52, 95% CI: 2.34-5.30, P<0.01) were associated with ISR after VAS operation in patients with ischemic cerebrovascular disease. Conclusions:Postoperative smoking, history of diabetes mellitus, history of hypertension, history of hyperlipidemia, history of coronary heart disease, high level of homocysteine, CYP2C19 mutation, shorter lesion vessel diameter, postoperative residual stenosis, use of bare metal stents and longer stent length are risk factors for ISR after VAS in patients with ischemic cerebrovascular disease. Clinical medical staff should adjust the follow-up time of postoperative patients according to risk factors and formulate individualized strategies to prevent the occurrence of ISR.

Objective:To observe the influence of NOD-like receptor thermal protein domain associated protein 6 (NLRP6) on hepatic ischemia-reperfusion injury (IRI), and elucidate the related mechanism.Methods:Thirty C57BL/6 mice with body weight of (18.80±1.99) g, were divided randomly into 5 groups, with 6 mice in each group: the mice that experienced only exploratory laparotomy were Sham group; that only underwent an operation to establish a hepatic IRI model were IRI group; that were treated with tail intravenous injection of clodronate (Clo) liposomes before the establishment of hepatic IRI model were Clo group; that received tail intravenous injection of clodronate liposomes and transfusion of bone marrow derived macrophages (BMDM) before the operation were Clo+ BMDM group; that received preoperative tail intravenous injection of clodronate liposomes and transfusion of BMDM with NLRP6 knockdown were Clo+ NLRP6-knockdown group. Real time quantitative polymerase chain reaction analysis (RT-PCR) and Western blot were performed to analyze the expressions of pyroptosis related proteins and factors. Simulate a hypoxia/reoxygenation (H/R) model in vitro, and set up experimental groups: lipopolysaccharide (LPS) + adenosine triphosphate (ATP), LPS+ ATP+ NLRP6-knockdown, H/R, and H/R+ NLRP6-knockdown. The changes of expressions of pyroptosis related proteins and factors were detected by RT-PCR and Western blot. Expression of NF-κB in vivo and in vitro was measured.Results:Compared with those in Sham group, protein expressions of NLRP6, NLRP3, Caspase-1, gasdermin D (GSDMD), IL-1β and IL-18 were remarkably increased in IRI group, but the levels of these proteins were dramatically decreased in Clo group with the exhaustion of macrophages in comparison with in IRI group, which were significantly different statistically (all P<0.05). The levels of these proteins were enhanced again in Clo+ BMDM group with the reconstruction of macrophages in contrast to those in Clo group, while the enhancements were more obvious in Clo+ NLRP6-knockdown group comparing to those in Clo+ BMDM group, with significant differences (all P<0.05). In vitro, pyroptosis rate for LPS+ ATP group was (16.39±1.06)%, which was lower than (27.34±2.79)% for LPS+ ATP+ NLRP6-knockdown group, with a statistical significance ( P<0.05). Meanwhile, pyroptosis rate for H/R group was (20.59±5.66)%, also much more reduced than (37.76±2.00)% for H/R+ NLRP6-knockdown group ( P<0.05). Expressions of NLRP3, Caspase-1, GSDMD, IL-1β, IL-18 and NF-κB p65 in LPS+ ATP+ NLRP6-knockdown group were more elevated than in LPS+ ATP group, and these indices were also more enhanced in H/R+ NLRP6-knockdown group than which in H/R group. Compared to the Sham group, expression of NF-κB p65 significantly increased in IRI group, which was reversed in Clo group, but enhanced again in Clo+ BMDM group and reached a peak in Clo+ NLRP6-knockdown group. Conclusions:Macrophage plays a critical role in immune response to hepatic IRI, wherein NLRP6 functions specifically. NLRP6 acts to suppress inflammation during hepatic IRI through regulating macrophage pyroptosis via inhibiting NF-κB.

Objective To understand the colonization status of Streptococcus pneumoniae and Haemophilus influenzae in nasopharynx of healthy infants in Wuhan. Methods Six vaccination clinics were randomly selected, and the nasopharyngeal specimens of healthy infants were collected and cultured for Streptococcus pneumoniae and Haemophilus influenza. Results The carrying rate of Streptococcus pneumoniae and Haemophilus influenzae in 998 healthy infants was 18.84% and 17.54%, respectively. The carrying rate of Streptococcus pneumoniae and Haemophilus influenzae within 6 months of age was 15.79% and 14.39%, and the carrying rate of Streptococcus pneumoniae and Haemophilus influenzae at 7-12 months old was 22.90% and 21.73%, respectively. The difference was statistically significant (Sp: χ²=5.60 P=0.02; Hi：χ²=8.98　P=0.00); The carrying rate of Streptococcus pneumoniae in urban and suburban areas was 18.08% and 19.78%, respectively, and the Haemophilus influenzae carrying rate was 17.18% and 17.98%, respectively. The differences were not statistically significant (Sp：χ²=0.47　P=0.50; Hi：χ²=0.11　P=0.74). The correlation coefficient (r value) of the age of the month and the carrying rate of sp and hi was 0.98 and 0.96, respectively. Conclusion The age of healthy infants in Wuhan was highly linearly and positively correlated with the carrying rate of Streptococcus pneumoniae and Haemophilus influenza.
