OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.
METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.
RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.
CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P < 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

OBJECTIVETo investigate the incidence and variation of tunnel enlargement after anterior cruciate ligament (ACL) reconstruction with peroneus longus muscle combined with BMP and allogeneic bone.
METHODSACL reconstructions with peroneus longus muscle combined with BMP and allogeneic bone were performed in 18 patients (18 knees)in the study from March 2007 to July 2009. Among the patients,14 patients were male and 4 patients were female, ranging in age from 21 to 47 years, with an average of 35.5 years. Twelve patients had the injuries in the right knee and 6 patients in the left knee. The CT scans were taken in a consistent manner at the 1st week and the 3rd, 6th, 12th months after surgery to measure tibial and femoral tunnel expansion.
RESULTSTunnel enlargement didn't happen in 18 knees. The average enlargement of 18 cases of femoral tunnel was (1.10 +/- 0.42) mm; and the average enlargement of 18 cases of tibial tunnel was (1.00 +/- 0.51) mm. There was statistical significance of femoral tunnel between the 1st week and the 3rd month after surgery (P < 0.05); and there were no significant difference of the tunnel diameters among the 3rd, 6th, and the 24th months postoperatively (P > 0.05). There was statistical significance of tibial tunnel between the 1st week and the 3rd month after surgery (P < 0.05); there were no significant differences of the tunnel diameters among the 3rd, 6th, and 24th months postoperatively (P > 0.05).
CONCLUSIONAnterior cruciate ligament reconstruction with peroneus longus muscle combined with BMP and allogeneic bone could obviously reduce the incidence of tunnel enlargement. The tunnel diameter obviously increase in 3 months after surgery,and it remains basically unchanged later.

OBJECTIVETo access the sustained immune effect in influenza A H1N1 vaccine vaccinated-blood donors as well as the level of anti-H1N1 IgG in unvaccinated-blood donors in order to provide reference for preventing and treating influenza A H1N1.
METHODSAnti-H1N1 IgG was detected in 1166 vaccinated-blood donors as well as 1265 unvaccinated-blood donors by ELISA method in Dongguan from January 2010 to June 2010.
RESULTSThe mean positive rate and high-titer rate of anti-H1N1 IgG were 78.82% and 46.57% respectively, both of which were sustained at relatively high level after reaching their peak at vaccination time of 71-90 d. The mean positive rate of anti-H1N1 IgG in unvaccinated-blood donors was 26.01%. No difference was found in the positive rate of anti-H1N1 IgG among different gender or age groups (P > 0.05).
CONCLUSIONThe influenza A H1N1 vaccine, with good sustained immune effect, plays an important role in preventing and treating influenza A H1N1. The positive rate of anti-H1N1 IgG in influenza A HIN1 vaccine unvaccinated-blood donors is low. Vaccination should be strengthened.

Objective To investigate the role of β-endorphin (β-EP) in conA-induced spleen cell proliferation after traumatic hemorrhagic shock. Methods ①Wistar rats with traumatic hemorrhagic shock were used and killed 0, 1, 3, 6,12 and 24 h after traumatic hemorrhagic shock. Plasma specimens were collected and β-EP levels in plasma were detected. Rats with sham-operation served as the control. ②Spleen cells isolated from normal rats were cultured in shock plasma (group Ⅰ), inactivated shock plasma (group Ⅱ) and shock plasma+β-EP antiserum (group Ⅲ) respectively. Con A-induced spleen cell proliferation was observed. Results ①The plasma β-EP level was elevated significantly immediately after shock, and reached the peak 1 h later, then showed a deceasing tendency and restored to the level as before shock at 24 h. ②Shock plasma remarkedly suppressed spleen cell response to the mitogen conA (P<0.01) compared with control; ConA-induced spleen cell proliferative function in group Ⅱ was significantly increased than that in group Ⅰ (P<0.01), so did in group Ⅲ, which still lower than in control. Conclusion The significantly elevated β-EP in the plasma after hemorrhagic shock might play an important role in inhibiting the proliferation of spleen cells.

OBJECTIVETo construct an eukaryotic expression plasmid containing gp120 gene of HIV-1 subtype B and obtain gp120 gene expression in HepG2 cells.
METHODSAccording to the published gp120 gene sequence in Genbank, a pair of primers was designed and synthesized. The PCR amplification product of gp120 gene was cloned into pMD-18T vector using TA cloning followed by BamHI and XhoI digestion and sequence analysis. The target gene was then subcloned into a highly efficient eukaryotic expression vector pcDNA3.1 (+). The recombinant plasmid was sequenced and identified by restrictive endonuclease digestion, and transfected into HepG2 cells via liposome. The expression of gp120 gene was analyzed by RT-PCR and Western blotting, respectively.
RESULTSRestriction endonuclease digestion and sequence analysis verified successful construction of the recombinant vector pcDNA3.1(+)/gp120. The target fragment gp120 was identical with U26942 in Genbank, and the expression of gp120 gene was detected in the lysate of the transfected HepG2 cells by RT-PCR and Western blotting.
CONCLUSIONThe eukaryotic expression plasmid for gp120 has been constructed successfully, which is capable of stable expression in HepG2 cells.

AIMThrough studying local regulatory mechanisms in pulmonary arteries (PA) and thoracic aortae (TA) under simulated microgravity (SM), to collect some data for the researches of adaptive mechanisms in pulmonary and systemic arteries and for the mechanisms accounting for orthostatic intolerance after SM.
METHODSCardiopulmonary circulatory function during 7-day 6 degrees head down bed rest (HDT) in male young volunteers was measured with a XXH-2000 pulmonary circulation and cardiac function instrument. - 30 degrees C tail suspended (TS) rats were used as the model to simulate the physiological effects of M. The PA and TA changes of vasoreactivity were respectively observed by vitro vessel rings perfusion.
RESULTSThe changes in volume of PA and pulmonary vein during a cardiac cycle and the preload in left cardiac ventricle in men increased significantly in the initial HDT. The super-regulatory phenomena appeared in both pulmonary and systemic circulation, but earlier and more obviously in pulmonary circulation than systemic circulation during 96-144 h. The dilatory reactivity in TS7 PA increased significantly, tended to decrease in TS14. The dilatory reactivity of TA in TS7 had a significant increase, had a slight increase in TS14. The contractile reactivity of PA decreased slightly in TS7 from CON, and were attenuated significantly in TS14. The contractile reactivity of TA in TS14 decreased significantly. The responsiveness to KCl, phenylephrine and sodium nitroprusside in VEC- removed PA had no differences among all groups.
CONCLUSIONThe differences in changes between pulmonary and systemic arteries under SM could be an important sign of depressed local regulatory function, which might be mainly due to dilatory function in VEC and contribute to the occurrence of orthostatic intolerance after SM.
