Method: Adopt overall sampling method. Patients who used the same adjuvant drugs from January to December 2020 were randomly divided into an intervention group and a control group. The patients in the two groups received routine nursing guidance and drug prevention for the use of amygdalin. The patients in the intervention group were required to take protective measures of Regional cooling during chemotherapy. The occurrence of hand foot syndrome during adriamycin liposome administration was compared between the two groups. Results: By comparing the adverse reactions of cases during Adriamycin Administration, the incidence rates of grade I, II and III hand foot syndrome in the control group were 28.8%, 7.6% and 27.5% respectively, and the incidence rates of grade I, II and III hand foot syndrome in the intervention group were 42.1%, 12.3% and 7.0% respectively, with statistical significance (P Conclusion: Regional cooling nursing and preventive behavior guidance can effectively reduce the severity of hand foot syndrome caused by adriamycin.展开更多

文摘Aims:To determine the safety and efficacy of microwave ablation(MWA)and transarterial chemoembolization(TACE)with doxorubicin hydrochloride liposome(DHL)in patients with primary liver cancer(PLC)and metastatic liver cancer(MLC).Materials and methods:The medical records of patients with primary or metastatic liver cancer who underwent MWA combined with TACE containing DHL from March 2019 to March 2022 were collected and analyzed.Treatment-related adverse events(AEs)were recorded.Local tumor response was evaluated according to the modified RECIST criteria.Local tumor progression-free survival(LTPFS)and overall survival(OS)were calculated using the Kaplan-Meier method.Results:Altogether,96 patients with liver cancer were included(PLC,n=45;MLC,n=51).Forty(41.7%)patients experienced AEs during treatment,and eight(8.3%)patients developed grade 3 AEs.Compared to before treatment,the serum total bilirubin level and neutrophil to lymphocyte ratio significantly increased after treatment.The median LTPFS was 14.5 months in patients with PLC and 10.7 months in patients with MLC.The median OS was not reached in patients with PLC or MLC.The 1-month and 3-month disease control rates reached more than 80%in both groups.Conclusion:MWA combined with TACE with DHL may be a safe and effective method for the treatment of liver cancer.
文摘Objectives: A non-clinical study was performed to establish a LC-MS/MS method to determine the in vivo active components of doxorubicin hydrochloride liposome injection in the plasma of Sprague-Dawley rats. Methods: Ten male SD rats were administered tail vein with a single dose of 10 mg/kg, and the concentrations of doxorubicin hydrochloride in plasma, heart, liver, spleen, lung, and kidney were determined by liquid chromatography-tandem mass spectrometry, and the pharmacokinetic parameters were calculated. Results: The final concentration of doxorubicin hydrochloride ranged from 500 ng/mL to 250,000 ng/mL, and the lower limit of quantification was 500 ng/mL;the main pharmacokinetic parameters: T<sub>1/2</sub> was (19.282 ± 10.305) h, C<sub>max</sub> was (118514.828 ± 26155.134) ng/mL, AUC<sub>0-24</sub> and AUC<sub>0-∞</sub> were (1216659.205 ± 192706.268) ng/mL⋅h and (2082244.523 ± 860139.487) ng/mL⋅h, MRT<sub>0-24</sub> and MRT<sub>0-∞</sub> were (9.237 ± 0.423) h and (26.52 ± 14.015) h, respectively, and clearance (CL) was (0.005 ± 0.002) mL/h⋅ng. Conclusions: The method is simple, rapid, and sensitive, which can be used for the determination of doxorubicin hydrochloride concentration in the plasma of SD rats and pharmacokinetic non-clinical studies.
文摘Purpose: To explore the preventive effect of Regional cooling comprehensive nursing on hand foot syndrome caused by pegylated liposomal doxorubicin (PLD). Method: Adopt overall sampling method. Patients who used the same adjuvant drugs from January to December 2020 were randomly divided into an intervention group and a control group. The patients in the two groups received routine nursing guidance and drug prevention for the use of amygdalin. The patients in the intervention group were required to take protective measures of Regional cooling during chemotherapy. The occurrence of hand foot syndrome during adriamycin liposome administration was compared between the two groups. Results: By comparing the adverse reactions of cases during Adriamycin Administration, the incidence rates of grade I, II and III hand foot syndrome in the control group were 28.8%, 7.6% and 27.5% respectively, and the incidence rates of grade I, II and III hand foot syndrome in the intervention group were 42.1%, 12.3% and 7.0% respectively, with statistical significance (P Conclusion: Regional cooling nursing and preventive behavior guidance can effectively reduce the severity of hand foot syndrome caused by adriamycin.
文摘Visceral leishmaniasis(VL),also known as Kala-azar,is caused by Leishmania(L.)donovani complex,which includes L.donovani and L.infantum and is associated with a high death rate as compared to the cutaneous and subcutaneous form.Treatment of VL includes chemotherapeutic agents which are associated with some major hurdles like toxicities,parenteral administration,high cost,parasite resistance and stability.Hence,there is an urgent requirement to develop novel chemotherapeutic agents or repurposing of existing drugs against VL.Developing formulation of new chemical entity for the treatment of VL is laborious,time consuming and associated with huge financial burden.However,screening of existing chemotherapeutic agents is a good alternative to avail cost-effective treatment option for VL.Non-PEGylated liposome encapsulated doxorubicin(Myocet®)is proposed as an alternative treatment option for VL in this review article.Here,we covered the fundamental aspects of VL,loophole associated with available current treatment strategies and non-PEGylated liposome encapsulated doxorubicin as a novel alternative formulation for treating VL,as this liposomal delivery system of doxorubicin might passively target the intra-cellular regions of macrophage.

文摘A giant cell tumor occurs mainly in the proximal tibia,humerus,distal radius bone and the pelvic bone.It is rarely observed in such sites as the ribs and the temporal bone.The condition is primarily treated with surgical excision and functional reconstruction.The effect of chemotherapy on lung metastases and locally advanced giant cell tumors has remained unknown.We collected and analyzed the data of six patients with rare giant cell tumors located in the head and neck patients.After an average follow-up of 42.6 months after surgery (14 to 90 months),no local recurrence or metastasis was observed.We also collected and analyzed the data of five patients with metastatic giant cell tumors who were undergoing surgery for the primary tumor before; of three patients who had experienced multiple chemotherapy cycles,one had spontaneous regression,and one survived for long timer despite progression.The other two patients had their major metastatic lesions resected by surgery,and presented long-term survival during the follow up.In addition,this study reports one patient with locally advanced giant cell tumor of the rib,who has undergone successful surgical resection following two cycles of chemotherapy with ifosfamide and liposomal doxorubicin.Complete resection of the lesion at the head and neck is the key to relapse-free survival.The prognosis of lung metastases in patients with giant cell tumors is relatively satisfying.Neoadjuvant chemotherapy is also conducive to the surgery for locally advanced lesions and improvement of the quality of life.
