OBJECTIVE To re-evaluate systematic review/meta-analysis of escitalopram in the treatment of depression, and to provide reference for clinical use of escitalopram. METHODS Retrieved from CNKI, Wanfang database, VIP, SinoMed, PubMed and the Cochrane Library, etc., systematic review/meta-analysis of escitalopram in the treatment of depression were collected from the construction of the database to May 17, 2022. The literatures were screened according to the inclusion and exclusion criteria, the basic information of the included literatures was extracted, and the methodological quality, reporting quality and evidence quality of the included literatures were evaluated by using AMSTAR 2 scale, PRISMA statement, and GRADE system, respectively. RESULTS A total of 16 systematic reviews/meta-analyses were included. The results of efficacy comparison showed that escitalopram in the treatment of depression was superior to sertraline in improving the total effective rate, and was comparable to paroxetine, duloxetine and fluoxetine in improving cure rate. The results of safety comparison showed that the safety of escitalopram was higher than that of paroxetine and venlafaxine. The overall methodological quality evaluation of AMSTAR 2 scale was low, and all of them were rated as extremely low; main reason was the lack of many key items. PRISMA score was between 12 and 23 points. Among them, there were 5 literatures with scores >21 points, and the reports were relatively complete, 10 literatures with scores between 15 and 21 points, and the reports had certain defects, and 1 literature with scores ≤15 points, with serious information missing. The results of the grading of GRADE evidence showed that, of the 160 included outcome indicators, 69 were moderate evidence, 64 were low-level evidence, and 27 were very low-level evidence. CONCLUSIONS The total effective rate of escitalopram in improving depressive patients is not inferior to that of sertraline; compared with paroxetine, escitalopram is safer. However, the evidence level of the above conclusions is low.

From air bacteria capable of decomposing creatinine, three single independent strains K9510、K9511 and K9512 have been isolated. The highest creatinine amidohydrolase (EC 3.5.2.10; creatininase) producing strain K9510 was screened out. The strain K9510 was identified as Pseudomonas sp. The results of culture condition for creatininase formation by strain K9510 were obtained as follows: creatinine and creatine were found to be the effective inducers for enzyme formation; the solution of mixed metallic salts could stimulate cell growth and enzyme formation. The suitable medium for creatininase formation was consisted of 0.9% creatinine、 0. 15% yeast extract、 0. 09% malt extract、0.05% NH4C1 and some amount of the solution of mixed metallic salts at pH5. 5. When the bacterium was grown in 250mL conic flask containing 50mL of the medium mentioned above on the rotary shaker(250r/min) at 35℃ for 33 h, about 50 u creatininase was obtained.

Objective To investigate the role of insulin resistance index (HOMA-IR) in premonishing hepatogenous diabetes subsequent to chronic liver disease related to hepatitis B virus. Methods Fasting plasma glucose (FPG) and fasting serum insulin (FINS) were measured in 176 patients, including 80 patients with chronic hepatitis B (CHB), 66 patients with liver cirrhosis (LC) and 30 patients with chronic severe hepatitis B (CSHB). In addition 30 healthy subjects served as control (group HC). None of the subjects in the study had a history of diabetes. FPG and FINS were measured in all the subjects to exclude impaired glucose tolerance and diabetes. Then HOMA-IR was calculated. Results Among the HC and CHB, LC and CSHB patients, both FINS and HOMA-IR levels gradually elevated. FINS and HOMA-IR in CHB patients (10.58?6.48, 2.35?1.55) were significantly higher than those in group HC (8.06?2.14,1.68?1.53), while lower than those in LC (12.73?5.88, 2.91?1.41) and CSHB (18.30?14.17, 4.35?3.17) patients (P0.05), while the values of FINS and HOMA-IR were significantly higher in severe patients than those in moderate patients (P0.05), while the values of FPG were significantly higher in LC and CSHB patients than those in group HC (P

Purpose To observe the impact of sleep deprivation (SD) for 24 hours on human brain regional homogeneity (ReHo) by using functional magnetic resonance imaging (fMRI),and briefly discuss the intervening effect of transcranial direct current stimulation (tDCS) on ReHo after SD.Material and Methods Sixteen healthy individuals were enrolled,and self-controlled study were adopted.Resting-state fMRI scans were performed in wakefulness,after SD,and after tDCS (true or placebo stimuli).The ReHo analysis approach was employed to calculate the ReHo values of whole brain in different states.The differences between before and after SD,and between true and false tDCS after SD,were analyzed.Results Compared with wakefulness,SD mainly enhanced ReHo in brain regions of left precentral gyrus,right precentral gyrus,bilateral temporal lobe and thalamus,but decreased ReHo in brain regions of right precuneus,left superior occipital gyrus,limbic lobe and bilateral angular gyrus,superior frontal gyrus,middle frontal gyrus.Compared with placebo stimuli,the true tDCS enhanced ReHo in brain regions of bilateral precuneus,angular gyrus and right forehead,superior middle gyrus,but decreased ReHo in brain regions of the medial side of left frontal lobe,right precentral gyrus,parahippocampal gyrus,substantia nigra and bilateral temporal lobe,pons and so on.Conclusion SD can cause ReHo change in a large number of brain regions.The tDCS on the prefrontal cortex improves the brain regions with ReHo reduction caused by SD.The improved brain regions mainly include bilateral precuneus/posterior cingulate cortex.Therefore,tDCS on the prefrontal cortex can improve brain dysfunction caused by SD.
