Résumé
Objective To observe the efficacy of electroacupuncture(EA) on the acupoint combination of He-(sea) points, front-mu points, and shu-points(abbrev. He-Mu-Shu) for the treatment of functional diarrhea, and to explore the effect of He-Mu-Shu point combination EA on the anxiety of patients. Methods A randomized controlled clinical trial was performed in 62 functional diarrhea patients. All of the patients were randomly divided into He-Mu-Shu group(32 cases) and medicine group(30 cases). He-Mu-Shu group was treated with EA on unilateral Quchi, Shangjuxu, Tianshu, Dachangshu point alternatively, and medicine group was treated with oral use of Loperamide hydrochloride capsules. Both groups were treated for 4 continuous weeks. Defecation frequency, stool property and anxiety scores were observed before treatment and 2, 4 weeks after treatment. Results After treatment, weekly defecation frequency, stool property and anxiety scores were improved in both groups, and the differences were statistically significant compared with those before treatment(P < 0.05). He-Mu-Shu point combination EA had better effect on improving weekly defecation frequency, stool property and anxiety scores of functional diarrhea patients than Loperamide hydrochloride capsules, and the differences were statistically significant (P < 0.05). Conclusion The clinical efficacy and anxiety-relief action of He-Mu-Shu point combination EA on functional diarrhea are superior to oral use of Loperamide hydrochloride capsules.
Résumé
OBJECTIVE: To detect whether there is mixing of norfloxacin in loperamide hydrochloride capsules by UPLC-MS. METHODS: The separation of norfloxacin was performed on C18 column with column temperature set at 35 ℃, and the mobile phase was composed of acetronitrile and 0.1% formic acid (gradient elution) with a flow rate of 0.3 mL?min-1. The sample size was 10 ?L. ESI source was applied with capillary tube tension at 3.0 kV and ion source temperature at 110 ℃, and scan mode was multiple reaction monitor. RESULTS: It has been proved that there was norfloxacin in 2 of the total 5 batches of samples based on the data of retention time of RP-HPLC including ultraviolet spectra, the quasi-molecular ion and the second order mass spectra split fragments. CONCLUSION: The method is highly selective and sensitive, and can be used to detect whether norfloxacin has been illegally added into loperamide hydrochloride capsules.
