ABSTRACT
Objective To compare the efficacy of partial splenic embolization (PSE)with 150－350 μm and 350－560 μm polyvinyl alcohol (PVA).Methods A total of 24 patients were analyzed retrospectively in this study.Among them,9 patients underwent PSE with PVA of 1 50－350 μm (group A)and 1 5 patients with PVA of 350－560 μm (group B).Hematological parameters including white blood cell and platelet counts before and 1 week after surgery were compared between the two groups,as well as postoperative complications. Results The white blood cell and platelet counts were both significantly increased after 1 week of surgery compared with that before surgery (both P＜0.05).Furthermore,group A had obvious advantage over group B in increasing platelets (P＝0.05).The incidences of postoperative complications were 100% (9/9)in group A and 87% (13/15)in group B,respectively,but the incidence and severity of complications between two groups were comparable.Conclusion PSE with PVA of 1 50－3 50 μm has advantage in postoperative platelet improvement over PVA of 350－560 μm.
ABSTRACT
Objective To evaluate the clinic effect of transcatheter arterial chemoembolization (TACE) by using arsenic trioxide (ATO) drug-bearing CalliSpheres beads (CB) in treating BCLC stage B hepatocellular carcinoma (HCC) . Methods The clinical data of 13 patients with advanced HCC, who received TACE by using CB loaded with ATO (CBATO) during the period from January 2017 to September 2017, were retrospectively analyzed. The clinical data, imaging materials, laboratory examinations, interventional complications, prognosis, etc., were summarized and evaluated. Results The patients were followed up for9-15 months, with a median period of 11 months. The survival rate was 100％. One, 3, 6 and 9 months after treatment, the disease remission (CR+PR) rates were 76.9％, 76.9％, 69.2％ and 61.5％ respectively, and the disease control rates were 92.3％, 92.3％, 92.3％ and 84.6％ respectively. In all 13 patients, no severe complications such as hepatic failure, renal insufficiency, bone marrow suppression, liver abscess, bile leakage complicated by infection and gastrointestinal bleeding occurred. Conclusion For the treatment of BCLC stage B HCC, TACE by using CBATO is safe and effective with reliable short-term effect.
ABSTRACT
OBJECTIVE To discuss the risk factors of professional exposure of dental health personnel and treatment measures. METHODS The management system of standardization,systematization,science and universal prevention were carried out and realized to maximally prevent the onset of dental hospital infection. RESULTS A set of feasible management system and measures about professional exposure for dental health personnel were drafted to make dental staff master the management standards of dental infection,realize the sterilization procedures of dental device and prevent dental infection maximally in dental hospital by implementing universal preventive measures during dental treatment. CONCLUSIONS The preventive measures and programs about professional exposure for dental health personnel must be structuralized.
