Effect of Cefazolin Sodium on Perioperative Prophylactic Anti-Infection in Patients Undergoing Gynecological Surgery

<p>Purpose: The purpose is to investigate the effect of cefazolin sodium on perioperative prophylactic anti-infection in patients undergoing gynecological surgery. Methods: 112 cases of gynecological surgery from January 2019 to April 2020 were divided into the control group and the observation group, with 56 cases in each group. They were given cefazolin sodium + metronidazole and cefazolin sodium monotherapy respectively. The perioperative white blood cells and the incidence of adverse reactions of the two groups were compared. Results: There was no difference in the normal rate of white blood cell count between the observation group and the control group (P &gt; 0.05), and no adverse reaction in the observation group, which was significantly lower than 7.14% in the control group (P &lt; 0.05). Conclusion: the use of cefazolin sodium in perioperative period of gynecological surgery can prevent infection, with advanced security, less adverse reactions and high value.</p>

Preparation and Activity Evaluation of the Novel Cu/TiO2 Nanometer Photocatalytic Materials

In this paper, the Cu/TiO2 thin film catalysts were prepared by alcoholthermal method with copper sheet as the carrier. In order to improve the degradation rate of antibiotic (cefazolin sodium), the synthesis conditions of Cu/TiO2 thin films were optimized. The physicochemical properties and activity were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray energy dispersion spectrometer (EDX), infrared spectrometer (FTIR), X-ray photoelectron spectrometer (XPS), high performance liquid chromatography (HPLC), chemical oxygen demand (COD) and spectrophotometry. The results show that the Cu/TiO2 catalyst had a uniform thickness of ∼200 nm and the particle size was about 0.4 nm, and the heterojunction between copper and anatase titanium dioxide has was successfully prepared. It can be found that when the dosage of TiF4 was 0.016 g, the tertiary butyl alcohol was 40 ml, the oven temperature was 130 °C, the oven reaction time was 24 h, the calcination temperature was 180 °C, and the calcination time was 2 h, the formed Cu/TiO2 catalyst can reach 58.1% for 3 h under visible light, with the photocatalytic degradation of 20 μg · mL–1 cefazolin sodium aqueous solution.

THERMAL STUDY OF SOLID COMPLEXES OF CERIUM, PRASEODIUM AND NEODIUM

Взаимодействием водных растворов хлоридов соответствующих редкоземельных элементов и натриевой соли цефазолина (NaCzl) были получены и выделены в твердом виде комплексные соединения цефазолина. Полученные комплексы имеют состав Me(Czl)•3HO, где Me = Ce+, Pr+, Nd+. Полученные соединения исследованы методом синхронного термического анализа. By the interaction of aqueous solutions of the chlorides of the corresponding rare-earth elements and the cefazolin sodium salt (NaCzl), complex compounds of cefazolin were obtained. The resulting compounds were investigated by synchronous thermal analysis.
