Clinical pathologic analysis of urologic primary primitive neuroectodermal tumor

Objective To explore clinico-pathological features,immunophenotype,treatment and prognosis of urologic primary primitive neuroectodermal tumor ( PNET) . Methods The clinical data of 3 patients with urologic PNET were analyzed retrospectively. All patients were male,aged 29,32 and 75 years respectively.

Clinical Practice Guideline of Traditional Medicine for Primary Osteoporosis

BACKGROUND Primary osteoporosis is a disease characterized by low bone mass and microarchitectural deterioration of bone tissue,leading to enhanced bone fragility and a consequent increase in fracture risk. Primary osteoporosis is particularly common in senile persons and in postmenopausal women.It ranks the fifth of diseases in the modern society.

Clinical Profile and Significance of Mucocutaneous Lesions of Primary Sjogren＇s Syndrome： A Large Cross-sectional Study with 874 Patients

Background： Mucocutaneous lesions are common features of primary Sjogren＇s syndrome （pSS）, but only a few studies have focused on them. To demonstrate the profile ofmucocutaneous lesions ofpSS and further explore their potential clinical significance, we perfermed a cross-sectional study on 874 patients. Methods： Demographic data, clinical manifestations, and laboratory results of 874 pSS patients were collected. Patients were divided into two groups according to the presence of mucocutaneous lesions. Differences in primary symptoms and systemic impairments between the two groups were analyzed. Results of laboratory tests were also compared alter excluding those who had taken corticosteroid from both groups. One-year follow-up was done, and occurrences of various new complications were compared. Results： Among the 874 pSS patients, 181 patients had mucocutaneous lesions, accounting for 20.7%. Multiple mucocutaneous manifestations were displayed, and the top four most common types of lesions were purpuric eruptions （39.8%）, urticaria （23.8%）, Raynaud＇s phenomenon （14.9%）, and angular stomatitis （9.9%）. Incidences of pulmonary interstitial fibrosis, pulmonary bullae, leukopenia, and anemia were significantly higher among patients with mucocutaneous lesions （P 〈 0.05）. Increase in lgG and decrease in C4 among patients with mucocutaneous lesions displayed statistical significance after excluding patients from both groups who had taken corticosteroid （P 〈 0.05）. Alter one-year follow-up, patients with mucocutaneous lesions presented a slightly higher incidence of new complications compared to those without. Conclusions： Mucocutaneous manifestations ofpSS patients were common and diverse. Patients with mucocutaneous manifestations had more systemic damages, higher level of IgG, and lower level of serum C4, suggesting a higher activity of the primary disease.

Relationship between ST-segment recovery and clinical outcomes after primary percutaneous coronary intervention: The HORIZONS-AMI ECG substudy report

Background In patients with ST-segment elevation myocardial infarction undergoing thrombolytic therapy, the degree of ST-segment resolution （STR） correlates with long-term cardiovascular mortality. The long-term predictive value of STR after primary percutaneous coronary intervention （PCI） is less well understood. We sought to determine the long-term prognostic value of STR after primary PCI in ST-segment - elevation myocardial infarction.
