Objective:To investigate effects and underlying mechanisms of glutathione persulfate (GSSH) on the level of testosterone in male obese mice.Methods:Totally 45 mice were divided into 3 groups on average. Low-fat diet (LFD)+normal saline (NS) group: 15 mice were fed with LFD for 10 weeks, followed by LFD together with daily intraperitoneal injection of saline for 45 d; high-fat diet (HFD)+NS group: 15 mice were fed with high-fat diet for 10 weeks, followed by HFD and daily intraperitoneal injection of NS for 45 d; HFD+GSSH group: 15 mice were fed with HFD for 10 weeks, followed by a HFD for 45 d and daily intraperitoneal injection of GSSH (200 mg/kg). After the treatment, all mice were killed with their necks-severed, testis and serum were taken out from the mice. Serum levels of testosterone and malondialdehyde (MDA), the mRNA levels of key enzymes for testosterone synthesis ( StAR, 3β- HSD, Cyp11a1 and Cyp17a1) were measured by RT-PCR. The testicular protein levels of StAR, 3β-HSD, NR5A1 and EHD3 were measured by Western blotting assay. Protein levels of NR5A1, SOD and Nrf2 were measured in mouse Leydig TM-3 cells that were treated with 50 μmol/L and 100 μmol/L GSSH, respectively, following with treatment with 100 μmol/L H 2O 2 . Results:1) After treatment, the body weight of mice in HFD+GSSH group did not change significantly, while the body weight of mice in HFD+NS group raised by 24.53% (from 32.46 g to 40.43 g) during the 45-day-intraperitoneal injection ( P=0.002). 2) Serum level of testosterone in HFD+NS group [(12.9±1.7) μg/L] was significantly lower than that in LFD+NS group [(18.3±1.2) μg/L, P=0.020]. However, serum level of testosterone in HFD+GSSH group was (25.42±2.1) μg/L, which was significantly higher than that in HFD+NS group ( P=0.030). The RT-PCR test results showed that compared with LFD+NS group, the expression levels of all key genes involved in testosterone synthesis ( StAR, 3β- HSD, Cyp11a1, Cyp17a1) showed a significant decrease in HFD+NS group ( P=0.003, P=0.007, P<0.001, P<0.001). The expression levels of these genes were restored in the mouse testes of HFD+GSSH group ( P=0.002, P<0.001, P<0.001, P=0.006). 3) Similarly, compared with LFD+NS group [(9.00±1.59) nmol/mL], the serum MDA level of HFD+NS group [(10.61±1.73) nmol/mL] raised significantly ( P=0.016), while GSSH reversed the raised HFD+NS high level of serum MDA in HFD+GSSH group [(9.23±0.94) nmol/mL, P=0.048]. 4) Both levels of NR5A1, EHD3, StAR, and 3β-HSD were reduced in HFD+NS group ( P=0.002, P=0.012, P=0.004, P=0.043), but their levels were significantly restored in HFD+GSSH group ( P<0.001, P=0.017, P=0.004, P<0.001). 5) The levels of NR5A1, Nrf2 and SOD were obviously down-regulated in TM3 cells treated with H 2O 2 ( P<0.001, P=0.002, P=0.004). Conclusion:GSSH can raise serum level of testosterone in HFD-fed mice by up-regulating expression of genes which are important for testicular testosterone biosynthesis.

H 1-antihistamines are widely used in the treatment of various allergic diseases, but there are still many challenges in the safe and rational use of H 1-antihistamines in pediatrics, and there is a lack of guidance on the prescription review of H 1-antihistamines for children.In this paper, suggestions are put forward from the indications, dosage, route of administration, pathophysiological characteristics of children with individual difference and drug interactions, so as to provide reference for clinicians and pharmacists.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

OBJECTIVE To compare the efficacy and safety of levetiracetam versus valproic acid in the treatment of pediatric epilepsy， and to provide evidence-based reference. METHODS The databases including CNKI， VIP， China Biomedical Literature Database， Wanfang data， PubMed， Embase and Cochrane Library were searched for the RCTs about levetiracetam （trial group） and valproic acid （control group） were collected from the inception to October 1st， 2021. After literature screening and data extraction， the quality of included literature was evaluated using the bias risk assessment tool recommended by Cochrane system evaluator manual 5.1.0 and RevMan 5.3 software were used for meta-analysis， sensitivity analysis and bias risk analysis. RESULTS A total of 33 RCTs were included， involving 3 116 patients in total. The results of the meta-analysis showed that the effective rate of trial group was significantly higher than control group [RR＝1.06， 95%CI （1.02， 1.11）， P＝0.003]. The subgroup analysis according to different courses of treatment showed that there was no statistical significance in the effective rate between 2 groups after 1 and 3 months of treatment （P＞0.05）； after 6 months of treatment， the effective rate of trial group was significantly higher than that of control group （P＜0.05）. The incidence of adverse drug reaction in trial group was significantly lower than control group [RR＝0.50， 95%CI （0.41， 0.61）， P＜0.000 01]； among specific adverse drug reactions， the incidence of nausea and vomiting in trial group was significantly lower than control group （P＜0.05）； but there was no statistical significance in the incidence of rash， drowsiness， abnormal mood， loss of appetite， dizziness or headache （P＞0.05）. Results of sensitivity analysis showed that study results were stable and reliable. Results of publication bias analysis showed that there was little possibility of publication bias in this study. CONCLUSIONS The short-term efficacy （1， 3 months） of LEV is similar to that of VPA in the treatment of pediatric epilepsy， but long-term efficacy （6 months） of LEV is better than that of VPA； moreover， LEV shows better safety in digestive system.

OBJECTIVE To analyze the clinical manifestations and characteristics of adverse drug reactions （ADR） caused by cefotaxime sodium in Shandong province， and to explore the effects of skin test before medication of cefotaxime sodium on serious ADR， so as to provide reference for safe drug use in clinic. METHODS The relevant data of cefotaxime sodium-induced ADR reported by Shandong Province ADR Monitoring Center during December 2019 to December 2021 were collected from National ADR Monitoring System. The ADR classification， age， gender， ADR occurrence time， route of administration， history of allergy， primary diseases， ADR systems/organs involved， clinical manifestations， outcome， skin test or not before medication were statistically analyzed. RESULTS A total of 1 057 ADR reports caused by cefotaxime sodium were included. Among them， there were 867 patients （82.02%） with general ADR and 190 patients （17.98%） with serious ADR. The majority were ＜11 years old （40.30%）. The main route of administration was intravenous drip （96.69%）. A total of 1 033 patients （97.73%） developed ADR 30 min to 24 h after medication. A total of 814 patients （77.01%） had no history of allergy. The primary diseases were respiratory system infection （56.58%）. Main systems/organs involved in ADR were skin and its appendants， digestive system and respiratory system， and its clinical manifestations were rash， pruritus， nausea， vomiting， chest tightness， etc. After withdrawal or symptomatic treatment， 1 050 patients （99.34%） were cured or improved. Before the use of cefotaxime sodium， 850 patients underwent skin test （151 patients occurred serious ADR）； there was no statistical significance in the incidence of serious renzhen202102@163.com ADR， compared with the incidence of serious ADR in 207 patients without skin test （39 patients occurred serious ADR）（P＝0.718）. CONCLUSIONS ADR caused by cefotaxime sodium is mainly seen in patients ＜11 years old， mostly occurring 30 min to 24 h after intravenous drip； skin test before medication of cefotaxime sodium cannot reduce the risk of serious ADR. Before using cefotaxime sodium in clinical practice， patients should be asked about their allergy and medication history in detail. During use， it is important to focus on the patient’s condition within 24 h after medication to prevent serious ADR and ensure the safety of clinical medication.
