tment policies.Electrocardiographic (ECG) criteria identifying right- and left-sided outflow tract origins have been established. The purpose of this study was to define the criteria for premature ventricular contractions (PVCs) originating from the right coronary cusp (RCC) adequately.We analyzed ECG and electrophysiologic study data from patients who underwent successful ablation of PVCs originating from the RCC and right ventricular outflow tract (RVOT). Eighteen RCC and 28 septal RVOT PVCs were studied. Among these 18 successful RCC PVCs, a predominantly positive QRS in lead I in 18/18 (100%), longer V1-2 R-wave duration (81.4 ± 31.1 vs 44.8 ± 7.0 ms, P = .02), V1-2 R wave duration index (RWDI) (51.3 ± 22.0 vs 31.2 ± 7.5%, P = .06) were observed compared to those with posteroseptal RVOT. Local ventricular activation time preceding QRS onset was significantly earlier (-38 ± 12 ms) at the successful RCC ablation site compared to the failed ablation site of the septal RVOT (-22 ± 8 ms), even without good pace mapping at the RVOT (P  less then  .001). The receiver operating characteristic curve showed that a pre-QRS time of ≥-31 ms predicted successful RCC ablation with 67% sensitivity and 94% specificity. A predominantly positive QRS in lead I, longer R-wave duration and RWDI in lead V1 or V2 with a local ventricular activation preceding QRS onset by an average of -31 ms suggests an effective RCC ablation site.RATIONALE Renal carcinoma is a common malignant tumor of the urinary system, 4%-10% of which are complicated with tumor thrombi in the renal vein and the inferior vena cava; in about 1% of patients, the inferior vena cava tumor thrombus invades the right atrium. Surgery is the treatment of choice. Real-time monitoring with transesophageal echocardiography (TEE) has been widely used in various operations, including cardiac and non-cardiac operations for congenital heart diseases, coronary diseases, vascular heart diseases, and aorta diseases, etc. In this article, a case of a patient with right renal carcinoma complicated with an inferior vena cava tumor thrombus is reported. check details PATIENT CONCERNS A 52-year-old man who was admitted to our hospital for lumbar pain lasting for one month. DIAGNOSIS Right renal carcinoma complicated with an inferior vena cava tumor thrombus. INTERVENTIONS Radical nephrectomy of the renal carcinoma and removal of an inferior vena cava tumor thrombus under real-time monitoring with TEE were performed. OUTCOMES Radical nephrectomy was successfully performed within 5 minutes after the inferior vena cava was clamped, and then the inferior vena cava tumor thrombus was removed. On the second day after the operation, the patient's conditions improved; his consciousness was clear; he was transferred to a general ward. On the third day after the operation, the patient was able to get out of bed and was discharged on the sixth day after the operation. LESSONS Real-time monitoring with TEE played an important role in many aspects in the radical nephrectomy of the renal carcinoma and removal of the inferior vena cava tumor thrombus.BACKGROUND This meta-analysis focuses on the controversial efficacy and safety of platelet-rich plasma (PRP) as compared with hyaluronic acid (HA) in the clinical treatment of knee osteoarthritis. We have attempted to provide an evidence-based medicine protocol for the conservative treatment of knee osteoarthritis. In addition, we included the latest relevant literature in this meta-analysis, and a staging study was conducted to compare the therapeutic effects of PRP and HA for knee osteoarthritis over different time periods. METHODS An online computer search with "platelet-rich plasma" and "knee osteoarthritis" as search terms was conducted in the PubMed, EMBASE, and Cochrane Library databases. We conducted a quality assessment of the retrieved literature and extracted the following indicators visual analog scale (VAS) score, subjective International Knee Documentation Committee (IKDC) score, Western Ontario and McMaster Universities (WOMAC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), and adverse events. RevMan5.3 software was used to determine the effect sizes, and indicators were compared across studies at three different time points from the administration of treatment. RESULTS A total of 14 randomized controlled trials (RCTs) involving 1350 patients were included. Long-term VAS, IKDC, WOMAC-Pain, WOMAC-Stiffness, WOMAC-Physical Function, and WOMAC-Total scores at each time point were higher in the PRP group than in the HA group. There were no significant differences in the remaining indicators between the two groups. CONCLUSION Compared with HA, PRP offers obvious advantages in the conservative treatment of knee osteoarthritis. Treatment with PRP can reduce long-term pain and improve knee joint function with no additional risks. Therefore, PRP can be widely used for the conservative treatment of knee osteoarthritis.The aim of this study was to evaluate the clinical use of tumor abnormal protein (TAP) in the diagnosis of different cancers.Totally 394 patients were divided into 4 groups, namely 100 healthy volunteers, 167 patients with cancer, 20 subjects with precancerous lesions, and 107 subjects with benign lesions. TAP was detected in 4 groups of research subjects using a TAP testing kit and examination system. We correlated TAP levels with a wide variety of clinical indicators as well as established cancer markers, including alpha fetoprotein (AFP) and carbohydrate antigen 19-9 (CA19-9). Besides, the changes of TAP level in 51 patients with liver cancer before and after surgery, and overall survival of patients with high or low TAP expression in pancreatic, gallbladder, bile duct, and liver cancers were analyzed.Statistically significant difference was observed in the TAP-positive ratio among subjects with cancer (79.6%) and precancerous lesions (45.0%) compared to the healthy volunteers (4.0%). TAP expression in different cancers was characterized by high sensitivity (79.64%), specificity (89.87%), positive and negative predictive value (85.25% and 85.71%), overall compliance rate (85.53%) but low omission and mistake diagnostic rate (20.36% and 10.13%), Youden index (0.6951). In addition, there was no significant difference among patients with different types of cancer (χ = 2.886, P = .410), and TAP expression was shown to be correlated with AFP in liver cancer (P = .034) but not with CA19-9 in pancreatic cancer (P = .241). Moreover, the overall survival of patients with low expression of TAP in pancreatic, gallbladder, bile duct, and liver cancers were significantly higher than of patients with high expression of TAP. Compared with the preoperative patients with cancer, TAP levels decreased dramatically among postoperative subjects (P  less then  .001).In summary, TAP might hold promise in serving as universal indicator for the diagnosis of different cancers.
