OBJECTIVETo explore therapeutic effects of Modified pinning combined with external tension band for the treatment of Gartland type III humeral supracondylar fractures in children.

METHODSFrom February 2009 to November 2010, 79 children with Gartland type III humeral supracondylar fractures were treated by modified pinning (pinning cross internal and external condyle assisted with lateral condyle) combined with external tension band (crossing needle end and hooking around) through lateral approach of elbow. There were 47 males and 32 females, with an average age of 8.7 years (ranging from 2.5 to 14 years). The time from injury to operation was 2 h to 8 d. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria were used to evaluate therapeutic effects.

RESULTSSixty-one patients were followed up (18 patients' data were lost) for 6-30 months (mean 13.5 months). According to Flynn criteria, 53 patients got excellent result, 7 good and 1 fair.

CONCLUSIONTreatment of child Gartland type III humeral supracondylar fractures with modified pinning combined with external tension band through lateral approach of elbow is believed to be an ideal method, which has advantages of reliable fixation, rapid recovery and less complications.

The care and support for the patient of AIDS is a vital content,we should enhance international collaboration and intercourse of information,which can promote efficiency.This text shows an analysis on the actuality and characteristic of the support mode of the AIDS community in British.Its purpose is to summarize the successful experience for china and improve the support mode for AIDS.

The composition of volatile compounds of soils and that of soil bacterial metabolites were identified by using the SPME-GC/MS method. Results showed that some compounds, trimethylamine, 3-methyl-2-pentanoe, dimethyl disulfide, methyl pyrazine, 2,5-dimethyl-pyrazine, benzaldehyde, N,N-dimethyloctylamine and nonadecane, subsisted commonly in soils and soil bacterial metabolites with strong fungistatic activity. These compounds may be the key antifungal factors in soil fungistasis, especially soil volatile fungistasis. Otherwise, the method used in this study was a good tool for further study of soil volatle fungistasis.

Objective To analyze the perioperative clinical character of the severe neurological complications in intracranial aneurism treated with stent-assisted coiling(SAC). Methods 203 cases of intracranial aneurysms patients treated by SAC were enrolled retrospectively(ruptured aneurysm group 45 cases and un-ruptured,aneurysm group 158 cases)and the perioperative clinical character of the serious neurological complications(11 cases)was further analyzed. Results The total rate of serious neurological complication was 5. 4%,11 cases of patients with 13 aneurysms got 13 stents. In the ruptured aneurysm group, 5 cases(11. 1%)suffered severe neurological complications,including intraoperative bleeding in one case, postoperative stent-related ischemia in one case,both 2. 2% . Postoperative bleeding 2 cases(4. 4%),and one case of bleeding during anesthesia induced stage(2. 2%). In the unruptured aneurysm group,intraoperative bleeding in three cases,and postoperative stent-related ischemia in three cases,both 1. 9% . No bleeding case during anesthesia induced stage or postoperative period. Although active rescue treatments were performed, 8 patients eventually died,and the total mortality rate was 3. 9% . Conclusion Intracranial aneurysms patients following SAC treatment may suffer from bleeding,ischemia,severe neurological complications, severe disability,and even die. So,we have to strengthen perioperative management.

Objective Toanalyzetheclinicalcharacteristicsandtreatmentoutcomesofspinalfilum terminalevascularmalformation.Methods Theclinicaldataof6patientswithfilumterminalevascular malformation diagnosed and treated from January 2008 to December. 2013 were analyzed retrospectively. The definition of filum terminale vascular malformation is anterior/posterior spinal artery feeding arteriovenous fistula or arteriovenous malformation and located below conus medullaris,and does not complicate with spinal vascular lesions in the other part. The Aminoff & Logue score and MRI of spinal cord function were performedatoneyearaftermicroneurosurgeryand/orendovascularembolization.Results Allpatients were males. Their clinical presentations were the weakness of both lower extremities and sphincter disturbance. The mean course of disease was 17. 1 ± 5. 2 months. The pathological type of the 6 patients were all arteriovenous fistulas. The feeding arteries included lumbar artery,internal iliac artery,and median sacral artery. Two of the 6 patients underwent Onyx glue embolization,3 were treated with microneurosurgery,and 1 was treated with embolization in combination with microneurosurgery. They were all achieved anatomic cure. The Aminoff & Logue scores were improved after 1 year (3. 8 ± 1. 9 scores before procedure,2. 8 ± 2. 0 scores after procedure),there was no significant difference (P >0. 05). The myodynamia scores were improved in 3 patients,2 did not change,1 got worse. The urinary and bowel functions were improved in 2 patients,and4didnotchange.Conclusion Filumterminalevascularmalformationisararevascular malformation of spinal cord. Both embolization and surgical treatment can achieve anatomic cure. Although the spinal cord function can be only partially restored,but continuous deterioration can be prevented.

ObjectiveTo observe the effect of rapamycin on the proliferation and cell cycle of prostate cancer cell lines PC3,and to investigate the mechanism that it inhibits the growth and metastasis of prostate cancer cells.MethodsPC3 cells were cultured in vitro,and treated with different concentrations (10,25ng/ml) of cycle raparnycine.MTT was used to measure the change of proliferation of PC3 cells.Flow cytometry was used to measure the changes of cell cycle and apoptosis of PC3 cells.Nude mice were used to detect the effect of rapamycin on metastasis.ResultsThe proliferation of PC3 cells was significantly inhibited by rapamycin,and a time- and concentration-dependent relationship was shown,the inhibited rate was(42.23 ± 0.78 ) ％ after 36 h in the group of 25 ng/ml ( P ＜ 0.05 ).Flow cytometry analysis showed rapamycin significantly inhibited the cell cycle,prompted the apoptosis,and increased the number of cells in G0/G1 phase at 36 h with a rate of cell staying at Go/G1 [ (92.17 ± 0.69 ) ％ ] ( P ＜ 0.05 ).The weight of tumors in nude mice in the control group was significantly greater than that in RPM group[ (3.41± 0.28)g vs ( 1.19 ± 0.23 )g] ( P＜ 0.05 ),and metastatic sites of the lung and liver in the control group were significantly mote than the RPM group [ 100％ (7/7) vs 14.29％ ( 1/7 ) ] ( P ＜ 0.05 ).Conclusions Rapamycin significantly inhibits the proliferation and metastasis of osteosarcoma.The rapamycin-based regimen is valuable for clinical application.
