Objective Objective To investigate the clinical characteristics and risk factors of elderly patients with acute ischemic stroke complicated with pulmonary infection. Methods A retrospective study was conducted on 1 113 elderly patients with acute ischemic stroke admitted to the department of neurology, Shenzhen Second People's Hospital from July 2017 to October 2019. Among them, 108 patients with stroke complicated with pulmonary infection were included in the infection group and 1 005 patients without concurrent pulmonary infection were included in the control group. The clinical data of the two groups were analyzed by single factor comparison, and the risk factors for pulmonary infection were analyzed by logistic multiple factor regression analysis. Results Single factor analysis showed there were statistically significant differences between the two groups in age (especially elderly patients), length of stay in hospital, atrial fibrillation, history of cerebral infarction, chronic pulmonary disease, dysphagia, slurred speech, and disturbance of consciousness (P <0.05). Multi-factor logistic regression analysis showed that old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech, and disturbance of consciousness were closely related to pulmonary infection in elderly patients with acute ischemic stroke. Conclusion The independent risk factors of acute ischemic stroke complicated with pulmonary infection in the elderly mainly include old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech and disturbance of consciousness, which should be paid more attention to clinically.

Objective To observe the expression of tight junction protein in hyperuricemia induced renal damage model in rats and the intervention effect of febuxostat. Methods SD rats were randomly divided into three groups: normal control group, model control group, febuxostat treatment group. Hyperuricemia was induced in rats with oxonic acid per time for three times per day, by gavage and combined with uric acid added in drinking water, while febuxostat were administered by gavage in febuxostat treatment group.The blood of rats were collected to analyse the differences of control, model and treatment group on changes of blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA). Immunohistochemistry was used to assay ZO-1 and occludin protein expression and quantitive real time PCR to detect the expression of ZO-1 and occludin in renal tissue of renal interstitial fibrosis model rats induced by hyperuricemia. Paraffin section of kidney was maked and then performed Masson staining to make sure the model is successful. Results At 6 weeks, the expressions of ZO-1 and occludin in the model group and treatment group were lower than those in the normal group (all P<0.05). The expressions of ZO-1 and occludin in the treatment group were higher than those in the model group (all P<0.05). Compared with the normal group, the RIF index in the model group and treatment group were higher (all P<0.05), and the RIF index in the treatment group was lower than that in the model group and higher than that in the normal group (all P<0.05). Conclusion The downregulated expression of ZO-1 and occludin plays a crucial role during the development of hyperuricemia in renal interstitial fibrosis, and are closely related to UA level and renal function impairment. Febuxostat may improve the expression of tight junction by downregurating UA, reduce renal fuction impairment and play a role in renal protection.

Methods AR42J cells were cultured and divided into 4 groups: normal control group, model group, miR-148a mimics group and miR-148a negative control group. miR-148a mimics and miR-148a negative control were transfected to AR42J cells with Lipofectamine 2 000, then cells were cultured for 48 h. The AR42J cells were stimulated with sodium taurocholate (TLCs) at a concentration of 200 μmol for 20 min, the normal control group was not treated, then the protein and RNA were extracted in each group. The expression of miR-148a was detected by RT-qPCR in each group. The activity of cells was detected by CCK8 assay in each group. The contents of IL-6, IL-1β and TNF-α in the cell culture medium were detected by ELISA. Western blot was used to detect the expression of autophagy related genes Beclin1, LC3Ⅰ and LC3Ⅱ. Results RT-qPCR results showed that the expression of miR-148a mRNA in model group was significantly lower than that in normal control group, while the expression of miR-148a mRNA in miR-148a mimics group was significantly higher than that in normal control group. The results of CCK-8 assay showed that miR-148a could significantly increase the activity of model cells stimulated by TLCs. The results of ELISA showed that the contents of IL-6, IL-1β and TNF-α in cell culture medium were significantly decreased after miR-148a mimics transfection, compared with the model group. Western blot showed that miR-148a mimics could significantly decrease the expression of Beclin1 and the ratio of LC3Ⅱ/LC3Ⅰ, compared with the model group. Conclusion miR-148a mimics was used to enhance the expression of miR-148a in cells model stimulated by TLCs, the expression of Beclin1 and the ratio of LC3Ⅱ/LC3Ⅰ were decreased, and the autophagy was inhibited. The release of IL-6, IL-1β and TNF-α was decreased and the activity of cells was increased. miR-148a plays a cellular protective role by regulating autophagy in model cells.

And in the control group, the setup errors were (2.8±2.1) mm, (3.9±2.2) mm, and (2.7±2.4) mm, respectively. The differences between the two groups were statistically significant (P<0.05). In the experimental group, the CTV-PTV boundaries in the anteroposterior, superoinferior and mediolateral direction were 5.27 mm, 8.54 mm, and 5.23 mm, respectively. And in the control group, the CTV-PTV boundaries were 8.47 mm, 11.29 mm, and 8.43 mm, respectively. Conclusion When using high-precision technology to treat cervical cancer, weekly kV-CBCT is a satisfactory and accurate positioning method, which helps to reduce the CTV-PTV boundary.
