Middle-term follow-up results of Pipkin type IV femoral head fracture patients treated by reconstruction plate and bioabsorbable screws / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To investigate the mid-term curative effects of the treatment of Pipkin type IV femoral head fractures using a reconstruction plate and bioabsorbable screws and provide the evidence for clinical practice.</p><p><b>METHODS</b>From February 2010 to September 2014, 21 patients with Pipkin type IV femoral head fractures were treated surgically. There were 13 males and 8 females with an average age of 41.1 years (range, 20-65 years). The causes of the fractures included traffic accidents (13 cases), falls from a height (four cases), heavy lifting injuries (three cases), and sport injury (one case). All patients were followed up with radiography and three-dimensional reconstruction computed tomography and other checks and any complications were actively managed. Closed reduction of fracture-dislocation of the hip was attempted under general anesthesia using the Kocher-Langenbeck approach. Femoral head fractures were treated with internal fixation or excision based on the size of the fracture fragments, whereas acetabular fractures were fixed with a reconstruction plate and screws following anatomic reduction.</p><p><b>RESULTS</b>The incisions healed by primary intention in all patients after surgery, without any infection, deep venous thrombosis, or other complications. All 21 patients were followed up for 36-76 months, with an average follow-up duration of 49 months. Postoperative imaging data showed that all dislocations and fractures were anatomically reduced, and bony union of the fractures was achieved. Heterotopic ossification was found in four patients, post-traumatic osteoarthritis in three, and avascular necrosis of the femoral head in two. At the final follow-up, the assessment of hip joint function according to the Thompson-Epstein scoring scale was excellent in 10 cases, good in six cases, fair in three cases, and poor in two cases. The rate of excellent and good functional outcomes was 76.1%.</p><p><b>CONCLUSION</b>The mid-term curative effects of a reconstruction plate and bioabsorbable screws in the treatment of Pipkin type IV femoral head fractures is significant, and such the treatment can significantly improve the patient's joint function and quality of life.</p>

Early and mid-term results of transarticular external fixation in the treatment of supination-external rotation type IV equivalent ankle fractures / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To investigate the early and mid-term results of open reduction and internal fixation (ORIF) with transarticular external fixation (TEF) but no deltoid ligament repair (DLR) in the treatment of supination-external rotation type IV equivalent (SER IV E) ankle fractures (AO/OTA classification 44-B 3.1) and provide evidence for clinical practice.</p><p><b>METHODS</b>This study cohort consisted of 22 patients with SER IV E ankle fractures that underwent ORIF with TEF but no DLR between December 2011 and December 2014. There were 13 males and 9 females, mean age 38.9 years (range, 17-73 years). Eight cases involved the left side and 14 the right side. The causes of fractures included road traffic accidents (11 cases), falling from height (6 cases) and sports injuries (5 cases). The mean period of hospitalization was 9.8 days (range, 6-14 days). For all the patients, MRI and three-dimensional CT were done before surgery and X-rays done preoperatively and during follow-ups. The external frame was kept for 8-10 weeks. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 56.86 ± 4.400, the Medical Outcomes Short Form 36-item (SF-36) questionnaire score was 57.41 ± 4.102 and the visual analog score (VAS) was 5.50 ± 1.058. Patients' main complaints about inconvenience of daily life were also recorded.</p><p><b>RESULTS</b>All the 22 patients were followed up for 24-63 months (mean, 33.6 months). None of them developed nonunion during the follow-up; pin site infection was observed in one patient and posttraumatic osteoarthritis in another. At the final follow-up, the average AOFAS score, SF-36 score and VAS score were respectively 90.59 ± 5.096, 79.59 ± 5.394 and 1.82 ± 1.181, which were significantly improved compared with the preoperative data (t = 26.221, p < 0.001; t = 11.910, p < 0.001; t = 11.571, p < 0.001). The therapeutic effect was excellent in 13 cases, good in 7 cases and fair in 2 cases, with a good-excellent rate of 90.9%. Patients' main complaints were inconvenience of clothing (17 cases) and extremity cleaning (5 cases).</p><p><b>CONCLUSION</b>In the treatment of SER IV E ankle fractures, ORIF with TEF but no DLR can achieve satisfactory outcome, but long-term effect should be confirmed by large sample randomized controlled trials.</p>

Lentiviral vector-mediated doxycycline-inducible iASPP gene targeted RNA interference in hepatocellular carcinoma / 癌症

<p><b>BACKGROUND AND OBJECTIVE</b>iASPP, an inhibitory member of the apoptosis-stimulating proteins of p53 (ASPP) family, has been found to be up-regulated in various human tumor types. This study was to construct an efficient doxycycline-regulated, lentiviral vector-mediated knockdown system for iASPP that will allow for inducible down-regulation of iASPP gene expression and preliminary functional analysis.</p><p><b>METHODS</b>A pair of complementary oligos with hairpin structures targeting the iASPP gene and a negative control were synthesized, then ligated with pLVTHM vector and sequenced. The fragment containing the shRNA cassette was cloned to pLVCT-tTR-KRAB plasmid. The recombinant vectors were co-transfected with viral packaging mix into 293T cells, and viral supernatant was harvested to determine the titer. After treatment with or without doxycycline, HepG2 cells infected with virus were harvested and the expression of iASPP was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Its effects on tumor growth were characterized using MTS assay, soft agar colony formation, and flow cytometry analysis.</p><p><b>RESULTS</b>The lentiviral vector expressing shRNA that targets to the oncogene iASPP was constructed successfully. HepG2 infected with the lentivirus expressing shRNA against iASPP inhibited the expression of iASPP in the presence of doxycycline, which resulted in the repression of tumor cell proliferation and anchorage-independent growth potential.</p><p><b>CONCLUSIONS</b>The lentiviral vector-mediated tet-on system demonstrates efficient and inducible knockdown of iASPP in hepatocellular carcinoma cells. iASPP gene may be involved in tumorigenesis and progression of human tumors.</p>

Survey on the situation of antenatal care in different regions of China, in 1971 - 2003 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To comprehensively understand the situation of antenatal care in the last thirty years and to identify the existing problems and challenges.</p><p><b>METHODS</b>PPS method was used to select those women under study and face to face interview was carried out at the house.</p><p><b>RESULTS</b>The quality and coverage rate of antenatal care as well as the rate of hospital delivery had been continuously increasing over time and the coverage rate of antenatal checkup had increased from 38.7% in 1970s to 95.9%, while the institutional delivery rose from 20.1% to 87.4% in the last three years. However, problems and challenges were found refering to the of delay first antenatal care, inadequate timing and with incomplete contents. Only 71.7% of the pregnant women had received first checkup during the first three months. 64.1% of the women received 5 times or more of the checkups while only 29.1% of the women had received all the 7 basic checkup items. Rate of hospital delivery was unsatisfactory that most (79.5%) of the women had the delivery not in the hospitals when under the assistance of midwife/village doctors. Indicators showed that the worst was in the western regions.</p><p><b>CONCLUSION</b>Great progress had been made in the field of antenatal care in last thirty yeats in China. The coverage rate of antenatal checkup and institutional delivery had been improved. But the quality of antenatal care should be further improved, especially in the western regions.</p>
