ABSTRACT
Objective:To evaluate the clinical efficacy of ultrasound-guided radiofrequency ablation therapy for patients with papillary thyroid microcarcinoma (PTMC).Methods:A retrospective analysis was conducted on the clinical data of 80 PTMC patients admitted to Zhongshan Hospital of Traditional Chinese Medicine(Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine) from January 2018 to September 2020. All cases were divided into two groups according to different treatment methods, with 40 cases in each group. The control group received PTMC radical surgery, while the observation group received ultrasound guided radiofrequency ablation. The situation of new tumors and cervical lymph node metastasis in both groups was observed through follow-up, the relative indexes of operation and safety of the two groups were compared.Results:There was no significant difference in the incidence of situation of new tumors and cervical lymph node metastasis between the two groups ( P>0.05). The operation time, intraoperative blood loss and hospital stay in the observation group were less than those in the control group: (20.23 ± 5.07) min vs. (54.51 ± 12.13) min, (1.68 ± 0.28) ml vs.(13.68 ± 2.31) ml, (1.82 ± 0.32) d vs. (5.43 ± 0.57) d, there were statistical differences ( P<0.05). The incidence of complications in the observation group was lower than that in the control group: 5.00%(2/40) vs. 25.00%(10/40), there was statistical difference ( P<0.05). Conclusions:Ultrasound guided radiofrequency ablation for the treatment of PTMC is safe and effective, minimally invasive in beauty, and can effectively reduce the incidence of complications.
ABSTRACT
Objective To investigate the effect of arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage. Methods 156 cases diagnosed with moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage were collected from October 2011 to October 2014. Lysholm knee score and preoperative examinations such as anteroposterior, lateral, axial radiographs, the standing full leg length X-ray film and MRI scan of the knee were recommended to definitively understand the osteoarthritis staging and meniscus injury grading. All patients were treated with arthroscopic debridement and meniscectomy. After operation, physical rehabilitation exercises and regular clinical follow-up were carried out as planned. The Lysholm knee score data from preoperation and terminal follow-up was statistical analyzed. Results No patient experienced any perioperative and postoperative complications. Statistical analysis showed that the Lysholm knee score of postoperation was significantly higher than that of preoperation [(87.3 ± 7.9) vs (67.5 ± 4.9), P < 0.05). Conclusion Arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage, gains beneficial effects for its minimal invasion and quick recovery.
ABSTRACT
Objective To observe the clinical effect of penehyclidine hydrochloride(Changtuoning)combined with atropine in treatment of patients with severe acute organophosphorus poisoning(AOPP). Methods The clinical data of 64 patients with severe AOPP admitted into Taizhou Municipal Hospital in Zhejiang Province and Quannan County People's Hospital in Jiangxi Province from January 2004 to September 2012 were retrospectively analyzed. Patients were divided into penehyclidine hydrochloride and atropine combined group(PH-A group,32 cases)and atropine treatment group(32 cases)depending on the difference in selection and application method of anticholinergic drugs. The application of anticholinergic drugs,length of mechanical ventilation,70%cholinesterase (ChE)activity recovery time,length of stay in hospital,incidence of complications,and cure rate were compared between the two groups. Results Compared with atropine treament group,the total usage of atropine in PH-A group was significantly decreased(mg:35.39±45.76 vs. 105.46±139.87,P0.05〕. Conclusion Penehyclidine hydroehloride combined with atropine in the treatment of severe AOPP can significantly improve the therapeutic efficacy,reduce the incidence of complications and length of stay in hospital.
