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.

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 summary the clinical features of 8 cases with ankylosing spondylitis (AS) complicated with systemic lupus erythematosus (SLE).Methods:This study was conducted retrospectively from January 2007 to November 2018. Eight patients with AS complicated with SLE who were admitted to Foshan Hospital of TCM were analyzed. Bath ankylosing spondylitis disease activity index (BASDAI) was compared using t-test. Results:Four patients were female. The mean age was (31±14) years, ranged from 16 to 59 years. The average disease duration of AS was (27±30) months(ranging from 4 to 144 months). The average disease of duration SLE was (69±51) months (ranging from 1 to 80 months). All patients was human lymphocyte antigen (HLA)-B27 positive. SLE-related organ involvement included kidney in 5 cases, leukocytopenia in 8 cases, arthralgia in 6 cases, nervous system in 1 case and skin rash in 3 cases. Renal biopsy were performed in 3 patients. And 2 cases were class Ⅲ+Ⅴ lupus nephritis, another one was class Ⅳ+Ⅴ lupus nephritis.Conclusion:AS may complicated with SLE. Some drugs may be able to active the potential SLE, which should be differentiated from drug-related lupus.
