Objective To study the clinical efficacy and safety of Bryan-Morrey approach combined with anatomic locking plate fixation for the treatment of type C fractures of distal humerus.Methods Performed a prospective study from from Mar.2011 to Aug.2014.Thirty-three cases of distal humerus fracture were included in our study,and the mean age was (37.3 ±4.1) years old.The fracture type of distal humerus was 13-C according to Mayo classification.All the fractures treated with a Bryan-Morrey approach and anatomic locking plates.In the follow-up,Mayo scores of elbow,measurement of range of motion,elbow flexion and extension muscle strength were recorded and analysed.Results In this study,there were no serious complications,such as nonunion,rupture of triceps tendon and the infection,except partial sensory function injury of ulnar nerve in 5 cases.At the last time of the follow-up,elbow flexion muscle strength and extension muscle strength did not significantly decreased significantly compared with strength of the normal side.The mean flexion of the injured side was (134.5 ± 10.1) degrees,and the mean extension was (-1 1.5 ± 8.1) degrees.According to Mayo elbow performance score,the average scores of elbow was (86.2 ± 7.8),84％ of the patients got excellent or very excellent function results.Conclusion The Bryan-Morrey approach combined with anatomic locking plate fixation is a good choice for the treatment of distal humerus fractures of AO C type.

AIM: To investigate the clinical features of acquired immune deficiency syndrome ( AIDS) patients associated ocular diseases in Urumqi and the relationship between ocular fundus manifestations and CD4+T cell count.
METHODS: The fundus of 93 AIDS patients were examined by indirect ophthalmoscopy. The clinical symptoms and CD4+T cell count of those patients with fundus changes were analyzed.
RESULTS: Thirteen patients were found having fundus changes which occurred in one eye of 4 patients and two eyes of 9 patients, respectively, and the total detection rate was 14. 0%. Seven patients had vision changes, and the main clinical features of retinal lesion were cotton wool spot and hemorrhage of retina. Four patients were diagnosed as retinitis with cytomegalovirus ( CMV ) infection and 9 patients were diagnosed as HIV related retinopathy diseases. Seven patients among 37 patients with CD4+T cell count ≤100cell/μL had fundus changes related AIDS, and the detection rate was 18. 9%; while 6 patients among 56 patients with CD4+T cell count >100cell/μL had fundus changes related AIDS, and the detection rate was 10. 7%. There was statistical difference between the two detection rates (P<0. 05).
CONCLUSION: No specificity was found of those patients with the clinical manifestation of HIV- related retinopathy, and those patients are easy to be missed diagnosis. A number of AIDS patients have fundus changes without any vision changes. Therefore, it is very useful for AIDS patients to be carried out the routine fundus examination for the early diagnosis and treatment.

Objective To investigate the characteristics of liver tissue pathology and immunohistochemistry in HBeAg negative hepatitis B virus infection and provide a reference for the diagnosis and treatment.Methods Liv-er biopsy was carried out on the 63 HBeAg negative HBV infections,then liver tissue inflammation,fibrosis and immu-nohistochemistry were detected.Results In HBeAg negative and HBV DNA negative patients,both the male and female,ALT normal and mildly abnormal group had no significant difference in liver inflammation and fibrosis(all P >0.05).Among the patients with fibrosis stage ≥S2,the ratio(30 /41,73.2%)of patients above 30 years old was higher than that below 30 years old (6 /14,46.2%)(P =0.041).There were no differences in liver tissue inflamma-tion(5 /34,14.7% vs.9 /29,31.0%)and fibrosis (8 /34,23.5% vs.8 /29,27.6%)between HBV DNA negative group and HBV DNA positive patients(all P >0.05).Only 2 cases of HBcAg positive in those 63 cases of liver tissue immunohistochemistry.Conclusion The liver tissues of HBeAg negative HBV DNA negative or positive patients have obvious liver inflammation and fibrosis,and the necessary treatment measures should be taken.HBcAg positive is extremely low in those liver tissue immunohistochemistry,which lead to the pathogenesis of liver inflammation needs further research.

AIM: To investigate the effects of Co-SZ eye drop on galactose cataract in rats. METHODS: Based on folk remedy, SZ eye drop was made from leech, as a modified SZ eye drop, Co-SZ eye drop was enriched in Zinc and Vitamin C. In the present study, animal model of galactose cataract in SD rats was used. All animals were randomly divided into 3 groups : control group(using 0.9 % NaCl instead of SZ and Co SZ), SZ group and Co-SZ group. Lens opacities were examined dynamically in each groups via FS-3V slit-lamp microscope. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH) and soluble protein (SP) in the lenses were measured in 15 days. RESULTS: Both the Co-SZ and SZ eye drops could significantly delay and alleviate galactose cataract in rats, with better effect of Co-SZ than SZ eye drop. The antioxidant index indicated that SOD, GSH-Px, GSH in Co-SZ and SZ group were significantly higher than that in control group. Furthermore, SOD, GSH-Px in Co-SZ group were higher than that in SZ group significantly. CONCLUSION: Co-SZ eye drops could significantly delay and alleviate galactose cataract in rats, the effect is much better than SZ eye drops. The different effect between SZ and Co-SZ eye drops could be raised from the different content of Zinc, which is involved in anti-oxidation.

Objective To study the value of DSA for hepatic vascular anatomy,and to evaluate the efficacy of portal vein occlusion in rabbits with hepatic VX2 tumor.Methods Twenty New Zealand white rabbits were randomly divided into two groups with 10 in each group,including test group A and positive control group B of ham operation.For the test group A,portal branch ligation(PBL)was performed for the left external branch after 3 weeks of the tumor implantation to the left external lobe.Two weeks later,the DSA of hepatic artery and portal vein were performed in all of the rabbits.Results The total displaying effectiveness of the branches of hepatic artery by DSA was better than that by vascular perfusion.There was hypovascular blood supply to hepatic artery implantation of the tumor in the test group A,comparing with that of the group B.Conclusion DSA can clearly display spacial details of the hepatic vascular anatomy in rabbits,and play an important role in post-procedual evaluation of the portal vein occlusion in rabbits.

PEG-modified magnetic Fe3O4 (Fe3O4-PEG) nanoparticles were sythesized using a solvothermal reaction and characterized with transmission electron microscopy (TEM) and thermo gravimetric analysis (TGA). The photothermal effect and photothermal destruction of cancer cells were evaluated. Then the doxorubicin loaded Fe3O4-PEG (DOX-Fe3O4-PEG) nanoparticles were prepared. The cytotoxicity and combined chemotherapy/photothermal therapy (PTT) effect were investigated. Uniform PEG coated Fe3O4 nanoparticles with particle size of 155 nm were obtained in the experiment. The loading and release of doxorubicin on Fe3O4-PEG were pH-dependent. The drug loading capacity in water was 21%. The results of MTT indicated a good biocompatiblity of Fe3O4-PEG nanoparticles and high cytotoxicity of DOX-Fe3O4-PEG. In combined therapy experiment, photothermal therapy demonstrated unambiguously enhanced chemotherapy efficacy. In conclusion, the obtained Fe3O4-PEG nanoparticles which exhibit good photothermal effect and drug loading capacity can be used for chemotherapy and photothermal therapy. The synergetic anti-tumor activity indicates the potential for the combined application of chemotherapy and photothermal therapy in cancer treatment.
