ABSTRACT
Background: Chemotherapy-induced diarrhea (CID) is a major challenge during chemotherapy, which not only affects the quality of life, but also reduces the effectiveness of chemotherapy. Aims: To evaluate the clinical efficacy of Bifid triple viable capsules in the treatment of CID in malignant tumors by using meta - analysis. Methods: Randomized controlled trials (RCTs) on Bifid triple viable capsules for the treatment of CID were retrieved from CNKI, Wanfang, VIP, China Biology Medicine disc, Chinese Clinical Trial Registry, PubMed, Embase, Cochrane Library, Web of Science and ClinicalTrails databases from the date of database establishment to December 2022. According to the inclusion and exclusion criteria, literatures were screened, extracted, and the quality of literature was evaluated. Meta - analysis was performed by using Stata/MP 14.0 software. Results: A total of 10 RCTs including 790 patients were enrolled. Meta - analysis results showed that efficacy of Bifid triple viable capsules in the treatment of CID was significantly increased than that of controls (OR=2.22, 95% CI: 1.69 - 2.92, P<0.000 1), and serum endotoxin, tumor necrosis factor - α, D - lactic acid, diamine oxidase were significantly decreased in Bifid triple viable capsules group than in controls (P<0.05). Conclusions: The addition of Bifid triple viable capsules adjuvant to the original symptomatic treatment of CID can optimize the treatment efficacy.
ABSTRACT
@#To investigate the stereoselective pharmacokinetics of itraconazole enantiomers in rats, four cis-ITR stereoisomers at the dose of 15 mg/kg were administered orally to rats. Blood was collected and single stereoisomer of ITZ and hydroxy-itraconazole(OH-ITZ)were determinated simultaneously by LC-MS/MS. Samples were extracted by protein precipitation with acetonitrile. Durashell HILIC column(100 mm×2. 1 mm, 5. 0 m)was used as the analytical column, while a mixture of solvent A(0. 02% acetic acid and 5 mmol/L ammonium acetate in water)and B(50% acetonitrile and 50% methyl alcohol)was used as the mobile phase. A 5. 5 min binary gradient elution(delivered at 0. 5 mL/min)was performed for the separation. LC-MS/MS was performed in positive ion mode with multiple reactions monitoring(MRM). The pharmacokinetic parameters of itraconazole enantiomers after the administration were estimated as follows: the plasma levels and AUC0-∞ of OH-(2S, 4R, 2R)-ITZ and OH-(2S, 4R, 2S)-ITZ were higher than those of OH-(2R, 4S, 2R)-ITZ and OH-(2R, 4S, 2S)-ITZ(P< 0. 001). At the same time, female rats exhibited greater cmax, t1/2, AUC0-∞ than male rats, and the absorption of male rats was more rapid than those of females. The findings indicate significant stereoselective differences in the pharmacokinetic parameters of itraconazole enantiomers and gender difference in rats.
ABSTRACT
Objective To investigate the effect of tramadol combined with sufentanil on postop-erative analgesia in patients received upper-abdominal surgery.Methods One hundred and fifty pa-tients scheduled for selective upper-abdominal operation were randomly divided into five groups (n=30 each):Tramadol group (T);large dose sufentanil combined small dose tramadol group (TS1 );balanced tramadol and sufentani group (TS2 );small dose sufentanil combied large dose tramadol group (TS3);sufentanil group (S).Postoprative VAS scores were recorded respectively at 1,4,8, 12,24,36,48 h when be in quiet and turning 90 degree,Ramsay sedation score,analgesia pump pressing times and side effects were also recorded.Results VAS scores in group TS2,group TS3 and group S at each time point both be in quiet and turning 90 degree were significantly lower than that of group T and group TS1 (P <0.05).Group S sedation score significantly higher than group T (P <0.05).No significant difference in other groups.Conclusion Balanced tramadol and sufentanil group has best analgesic effect and least side effects.With the increasing doses of sufentanil,its analgesic effect was not obvious enhancement.
