Bacterial infection is the main cause of infectious diseases in children. Antibacterials play an important role in anti infection treatment of children. At present, the treatment of antimicrobial drugs in children is facing a severe situation of bacterial resistance. In January 2020, a children′s specialized hospital carried out the practice of precise management of antibiotics in combination with key performance indicators. Through the multi sectoral linkage of management and technology, eight key performance indicators and assessment methods were set up from three levels of antibiotic use, bacterial resistance and hospital infection, to standardize the clinical application of antibiotics and continue to promote the rational use of antibiotics. This practice had improved the performance indicators of antibacterial management. Among them, the use intensity of antibacterial drugs for inpatients decreased from 40.07 DDD in 2019 to 29.00 DDD in 2021, the use rate of antibacterial drugs for inpatients decreased from 81.32% to 64.40%, the percentage of antibacterial drug expenses in total drug expenses decreased from 35.41% to 26.82%, the use proportion of non restricted antibacterial drugs in antibacterial drugs increased from 71.30% to 82.21%, and the drug resistance rate of Salmonella to β-Lactam/enzyme inhibitors decreased from 4.84% to 0.03%, and the incidence of hospital infection decreased from 1.16% to 0.96%. The precise management of antibiotics in combination with key performance indicators improved the level of rational use of antibiotics, effectively curbed bacterial resistance, achieved phased results, so as to provide a reference for the scientific management of antibiotics in children′s hospitals.

The purpose of this study was to develop and evaluate a transdermal delivery system for RIS using hydrogels. First, the effects of different concentrations of hydroxypropyl methylcellulose and Carbomer 934 [CBR] on RIS permeation were investigated in porcine skin. The optimized formulation was chosen as the base gel to screen for penetration enhancers. The pharmacokinetics of the optimized RIS formulation was then studied in vitro in rabbits. A formulation with 0.5% CBR showed the highest RIS permeation and was selected as the base gel. RIS permeation was further increased by incorporation of Azone, lauryl alcohol, or menthol, and the enhancing effects of the three were dosedependent. When each enhancer combined with propylene glycol [PG] a synergistic effect was found. A combination of 6% menthol and 6% PG exhibited highest RIS in vitro penetration rate and showed a high efficiency in vivo, with a relative bioavailability of 131.53% compared with intragastric administration. These findings showed that 1% RIS in 0.5% CBR, containing a combination of 6% menthol and 6% PG, can deliver doses of RIS that are therapeutically relevant for treating patients with schizophrenia

BACKGROUND:In the clinical treatment of diabetic retinopathy, the therapeutic effects of different filers on the retina and optic nerve after the removal of the vitreous are lack of comprehensive and detailed reports. OBJECTIVE:To observe the changes of retina and optic nerve in patients with diabetic retinopathy after filing cyclic polydimethylsiloxane. METHODS: Totaly 147 patients with diabetic retinopathy undergoing vitreous removal were enroled, including 77 males and 70 females, aged 35to70 years. The vitreous from 74 patients with diabetic retinopathy was filed with cyclic polydimethylsiloxane (test group). The cyclic polydimethylsiloxane was taken out at 3 months post-operation. The vitreous from another 73 patients with diabetic retinopathy was filed with the whole fluorine propane (control group). The changes of retina, optic nerve, intraocular pressure, and the occurrence of vitreous re-hemorrhage and cataract after operation were observed in these two groups. RESULTS AND CONCLUSION: After 7 days of folow-up, the intraocular pressure of patients in the test group was higher than that in the control group (P < 0.05). After 6 months of folow-up, there was no significant difference in the intraocular pressure between these two groups. After 6 months of folow-up, cyclic polydimethylsiloxane was successfuly removed in the test group, retinal blood vessels became thinning with the presence of white sheath, and the number of optic nerves was higher than the control group (P < 0.05). The incidence of vitreous re-hemorrhage and cataract in the test was higher than the control group (P < 0.05). These results demonstrate that after the removal of the vitreous, cyclic polydimethylsiloxane filing can lead to optic atrophy in patients with diabetic retinopathy.
