OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:Medical records of 300 inpa-tients receiving thymopentin were randomly sampled from our hospital during Jul. 2013-Jun. 2014. The indication,solvent dilution, route of medication,dosage,medication course and contraindications were analyzed and evaluated. Comment result fed back and ef-fective clinical invention was done. RESULTS:There was a certain degree of off-label use of thymopentin,and the off-label drug use accounted for 38.33%. Through examination and clinical intervention on clinical rational drug use, remarkable results had been achieved. Thymopentin prescription sampling were analyzed statistically in the third quarter of 2014,and the off-label drug use rate dropped to 14%. CONCLUSIONS:We should strengthen prescription comments and feedback,effective clinical invention should be done,to promote rational use of thymopentin.

OBJECTIVE:To provide reference for enhancing and standardizing the storage,dispensing and clinical use of the photophobic drug. METHODS:The management system and directory of photophobic drugs were set up in our hospital,and photo-phobic drug were classified into drugs used away from light strictly and drugs used away from light appropriately. Special training for nursing staff and monthly inspection of photophobic drug storage and use by inspection group could help finding problems and doing timely rectification. The number of wards where the problems of clinical photophobic drug use were found were compared be-fore and after management. RESULTS & CONCLUSIONS:After 3-quarter management,the quantity of wards with problems de-creased from 69 to 2,decreasing by 97.1%. The management reinforce of photophobic drug can effectively promote the manage-ment of drugs to be standard and scientific and improve the safety and effectiveness of photophobic drug use.

This article reviewed the pharmacokinetic and pharmacodynamic characteristics of ambroxol and the interactions be-tween ambroxol and antibacterial agents. The use order of ambroxol and antiseptic drugs was analyzed and discussed. Ambroxol was a-ble to increase antibiotics concentration in bronchoalveolar lavage fluid (BALF) samples. Besides, ambroxol could destroy the struc-ture of bacterial biofilm(BF) in a dose-dependent manner,and high dose of ambroxol hydrochloride showed good safety. When ambr-oxol and antibacterial agents were in combination use,ambroxol should be administrated before antibacterial agents in order to enhance antibacterial efficacy,since ambroxol could increase the concentration of antibacterial agents in lung and help the antibacterial agents enter the bacterial BF. It was suggested that the label of ambroxol be further improved and revised as follows:①the administration se-quence of ambroxol and antibacterial agents should be stated;②the recommended doses of ambroxol for different indications should al-so be listed in the label;③ the clinical safety and efficacy of high dose of ambroxol should be stated.

Objective To explore the prevalence of mild cognitive impairment (MCI) among elderly veterans. Methods 2 674 veterans ( aged 60 years and over) from 26 military sanatorium in Shijiazhuang city were studied. The Mini-Mental State Examination, Global Deterioration Scale, Activity of Daily Living, Hachinski Ischemic Scale and Hamilton Depression Scale were served as screening tools. Results The prevalence of total MCI was 8 08% in elderly people. The standardized prevalence of MCI was 6 87% in male and 10 38% in female (P

Objective:To investigate the value of generative adversarial networks-based PET image reconstruction in improving the quality of low-dose 18F-FDG PET images and lesion detection in pediatric patients. Methods:Retrospective analysis of 61 PET images of children (38 males, 23 females, age (4.0±3.5) years) who underwent 18F-FDG total-body PET/CT imaging in Beijing Friendship Hospital, Capital Medical University from August 2021 to December 2021 was performed. The low-dose images (30 s, 20 s, 10 s) of all children extracted by list mode were input into the generative adversarial networks for deep learning (DL) reconstruction to obtain the corresponding simulated standard full-dose images (DL-30 s, DL-20 s, DL-10 s). The semi-quantitative parameters of the liver blood pool and primary lesion of standard full-dose 120 s, 30 s, 20 s, 10 s, DL-30 s, DL-20 s, and DL-10 s images were measured. The target-to-background ratio (TBR), contrast-to-noise ratio (CNR), and CV were calculated. The 5-point Likert scale was used for subjective scoring of image quality, and the detective abilities for positive lesions of each groups were compared. The sensitivities and positive predictive values of positive lesions detection were calculated. Mann-Whitney U test and Kruskal-Wallis rank sum test and χ2 test were used for data analyses. Results:CNR of the 30 s, 20 s, and 10 s groups were lower than those of DL-30 s, DL-20 s, and DL-10 s groups, respectively ( z values: -3.58, -3.20, -3.65, all P<0.05). Score of DL-10 s group was significantly lower than those of 120 s, DL-30 s and DL-20 s groups (4(3, 4), 5(4, 5), 4(4, 5), 4(4, 5); H=97.70, P<0.001). There were no significant differences in TBR, CNR, CV, SUV max and SUV mean of lesions and liver blood pool in 120 s, DL-30 s, DL-20 s, and DL-10 s groups ( H values: 0.00-6.76, all P>0.05). The sensitivities of positive lesion detection in DL-30 s, DL-20 s, and DL-10 s groups were 97.83%(225/230), 96.96%(223/230), 95.65%(220/230), respectively, and the positive predictive values were 96.57%(225/233), 93.70%(223/238), 84.94%(220/259), respectively. The positive predictive value in DL-10 s group was lower than those in DL-30 s and DL-20 s groups ( χ2=23.51, P<0.001). There were more false-positive and false-negative lesions detected by DL-10 s group than those of DL-30 s and DL-20 s groups in different sites. Conclusion:Based on the generative adversarial networks, the image quality of DL-20 s group is high and can meet the clinical diagnostic requirements.
