Hypoxia-inducible factor-alpha-1 (Hif-lalpha) is an active-transcription nucleoprotein produced in cellular hypoxia condition, and HIF-1 can bring tissues into adaptation reaction when the tissues are in state of hypoxis. Apart from that, the factor is involved in angiogenesis of ovarian tumor, energy metabolism, invasive metabasis of the tumor and prognosis. Therefore, a new treatment of ovarian tumor may rely on the thorough study of the relationship between HIF-1 and the tumor by investigating its expression and mechanism.

BACKGROUND:Sodium hyaluronate injection after arthroscopic debridement of knee osteoarthritis can reduce postoperative pain and improve joint function, but there is a controversy on the time for the hyaluronate injection after arthroscopic debridement of knee osteoarthritis.
OBJECTIVE:To observe the time of hyaluronate injection after arthroscopic debridement of knee osteoarthritis, and to compare recent rehabilitation effect of knee sodium hyaluronate injection for knee function after
arthroscopic debridement of knee osteoarthritis between injection just after knee arthroscopy and injection 2 weeks after knee arthroscopy.
METHODS:The clinical data of 100 knee osteoarthritis patients undergoing sodium hyaluronate injection
immediately and 2 weeks after arthroscopic debridement were analyzed with prospective randomized control ed trial method, and the preoperative visual analog scale score, Lysholm score, 6 weeks postoperative visual analog scale score, 3 months postoperative visual analog scale score, and 3 months postoperative Lysholm score were recorded. The effects of recently rehabilitation of knee joint after surgery in two groups were compared.
RESULTS AND CONCLUSION:There was no significant difference in postoperative visual analog scale score between immediate injection group (6.52±2.38) and 2 weeks postoperative injection group (6.54±2.37). The preoperative Lysholm score in the immediate injection group (43.44±16.18) was lower than that in the 2 weeks postoperative injection group (51.12±16.3). The 6 weeks postoperative visual analog scale score in the immediate injection group (3.2±2.46) was significantly higher than that in the 2 weeks postoperative injection group (5.1±2.68). The 3 months postoperative visual analog scale score/Lysholm score in the immediate injection group (2.72±2.70)/(80.58±15.63) were significantly higher than those in the 2 weeks postoperative injection group (4.72±3.07)/(64.96±21.68). The results indicate that sodium hyaluronate injection immediately after arthroscopic debridement of knee osteoarthritis is more favorable for recent rehabilitation.

Purpose Blast lung injury is severe, and is the main causes of death in explosion. This paper aims to explore the imaging features of blast lung injury, and to provide reference for clinical diagnosis and care. Materials and Methods The clinical data of 37 patients with primary blast lung injury stricken in the 8.2 Kunshan explosion in 2014 were retrospectively studied, with regard to the degree of burn, area, auxiliary emergency treatment and medical history. The imaging manifestations of X-ray and/or CT were also analyzed. Results ① The X-ray and/or CT findings of chest showed that 6 cases (16.2%) presented no obvious abnormality of lung parenchyma, 14 cases (37.8%) manifested increase of lung markings and spot-like clouding opacity, 6 cases (16.2%) presented ground glass opacity, 7 cases (18.9%) manifested patchy shadow, 4 cases (10.8%) showed diffuse consolidation. 6 cases (16.2%) with pleural effusion, 6 cases (16.2%) complicated with pneumothorax and hydropneumothorax, 4 cases (10.8%) with enlarged podoid and pericardial effusion, 2 cases (5.4%) with mediastinal hematoma, 9 cases (24.3%) with rib fracture. The positive rate of X-ray film inspection was 72.2% (13/18), yet that of CT reached 92.9% (13/14). ② Five patients who had not been seen obvious abnormal in emergency lung examination appeared mottling shadows or flake fuzzy shadows in the examination on the second day; 9 cases with aggravated symptoms and infection signs displayed relieved signs, expanded or changed primary lesions. Conclusion Imaging examination is an important tool in the diagnosis of primary blast lung injury. CT is superior to X-ray film on the detection of lesions; therefore, CT examination on chest should be carried out as soon as possible if conditions are allowed.
