Long chain noncoding RNA FAM224B protects the lung tissue of rats with severe pneumonia and the underlying mechanism / 中国基层医药

Objective:To investigate the protective effects of overexpression of long-chain noncoding RNA FAM224B on lung tissue of rats with severe pneumonia and the underlying mechanism.Methods:From August 2020 to March 2021, we randomly allocated 20 rats into the pneumonia group (severe pneumonia modeling) and FAM224B group (severe pneumonia modeling + FAM224B plasmid), with 10 rats in each group. We performed a quantitative real-time polymerase chain reaction to detect the level of FAM224B in lung tissue and performed an enzyme-linked immunosorbent assay to detect the levels of tumor necrosis factor-alpha, interleukin-6, and interleukin-1β in lung tissue. We used the software starBase v2.0 to predict the target gene of FAM224B. We performed a quantitative real-time polymerase chain reaction to detect the expression of the target gene in lung tissue and performed a western blot assay to detect the protein expression of the nuclear factor-kappa B signal pathway in lung tissue.Results:FAM224B expression was (1.09 ± 0.23) and (10.12 ± 1.52) in the pneumonia and FAM224B groups, respectively. FAM224B expression was significantly lower in the pneumonia group compared with the FAM224B group ( t = 15.86, P < 0.01). The levels of tumor necrosis factor-alpha, interleukin-6, and interleukin-1β were (41.53 ± 2.46) μg/L, (34.01 ± 2.53) ng/L, (20.92 ± 1.95) μg/L in the pneumonia group and they were (21.71 ± 2.25) μg/L, (17.13 ± 3.01) ng/L, (11.97 ± 1.21) μg/L in the FAM224B group. There were significant differences in the levels of tumor necrosis factor-alpha, interleukin-6, and interleukin-1β between the two groups ( t = 15.94, 14.29, 13.89, all P < 0.01). FAM224B had complementary binding sites with miR-34b-5p. The expression level of miR-34b-5p in lung tissue was significantly lower in the FAM224B group compared with the pneumonia group ( t = 15.55, P < 0.01). The protein expression levels of phosphorylated nuclear factor-κB subunit (p-p65) and phosphorylated inhibitor of kappa B alpha in lung tissue were significantly lower in the FAM224B group compared with the pneumonia group. Conclusion:FAM224B overexpression reduces the inflammatory reaction in lung tissue of rats with severe pneumonia through inhibiting miR-34b-5p expression.

Clinical analysis of effects of statins in adjuvant treatment of 108 patients with cerebral infarction / 中国基层医药

Objective To explore the effect of statin in treatment of hypertensive atherosclerotic patients with cerebral infarction and the its effect in prevention cerebral infarction recurrence.Methods 108 hypertension patients with atherosclerotic cerebral infarction were randomly divided into two groups,each group had 54 cases.The control group received conventional treatment;the observation group was given combination therapy with statin and the conventional treatment.The efficacy was evaluated after 2 months.The blood pressure,blood lipid and cerebral function,cerebral infarction recurrence within 1 year after treatment in the two groups were observed.The clinical efficacy of the two groups was compared.Results After treatment,blood pressure,blood lipid indexes and brain function of the observation group were better than those of the control group(all P ＜ 0.05).The total effective rate of the observation group was 100％,which was higher than 76％ in the control group(x2 =9.488,P ＜ 0.05).The control group had 12 cases of recurrence(recurrence rate 22％),1 case recurrence in the observation group(recurrence rate 2％),with no significant difference between two groups (x2 =13.277,P ＜ 0.05).Conclusion The clinical efficacy of statins in the treatment and prevention of hypertension atherosclerotic cerebral infarction is safe and significant,which is worth to use in clinical practice.

Evaluation of the intervention for the treatment of burning mouth syndrome by evidence-based medicine / 实用口腔医学杂志

Objective:To determine the effectiveness of the interve ntion of burning mouth syndrome(BMS) reported by Chinese articles and to assess the quality of the studies by evidence-based medicine. Methods: relevant literatures were searched and identified in Chinese Medical Bio logical Database (CMB) and Chinese Technological Periodical Database (VIP) . Stu dies were selected with following criteria: study design- randomized controlle d trials; participants-patients with BMS. An evidence-based analysis was perfo rmed to the literatures. Results: There were totally 47 articles examined and only 11 of them met the criteria . Meta analysis was not possible due to the low quantity and poor quality, However, as far as the p ublished articles concerned, Lusunjing capsule showed good short-term effect in the treatment and nerve block with vitamin B 1 and B 12 was more effec tive than oral admenistering of vitamin. Conclusion: Th e quantity and quality of the reviewed studies are far from satisfaction and ca n not meet the clinical needs. Further trials of high methodological quality ne ed to be undertaken in order to develop effective treatment of BMS.
