OBJECTIVETo explore the relationship of the classification of talus fracture and surgery methods with avascular necrosis.

METHODSFrom March 2009 to November 2013, 78 patients with talus fracture were treated, of them, 43 cases were followed up from 2 to 5 years. There were 27 males and 16 females, aged from 17 to 65 years old with the mean of 38.6 years. Thirty-nine cases had talar neck injury and 4 cases had talar body injury. Different treatments were performed according to different injury conditions. The time from injury to treatment was from 6 to 48 hours. The effect of classification of talus fracture and surgery methods on avascular necrosis was analyzed.

RESULTSIn 43 cases,19 cases occurred avascular necrosis, including talar neck fracture of type I in 2 cases, type II in 5 cases, type III in 5 cases, type IV in 5 cases and talar body fracture in 2 cases (combined with talar neck fracture). And 29 patients were treated with operation, there was no statistically significant differences in avascular necrosis with different operations.

CONCLUSIONCompared with talar body fracture, talar neck fracture is more easily to develop into avascular necrosis. In the 4 types of talar neck fracture, the possibilities of type III and IV were the most ones.

Objective To investigate the clinic results of treatment of distal tibiofibular fractures by in- direct reduction and plate fixation through inferior fibula.Methods Between 2002 and 2005,32 cases of distal tibiofibular fractures were treated with indirect reduction and plate fixation through inferior fibula.According to the AO/ASIF classification,there were 17 cases of type A,nine cases of type B,and six cases of type C.Twenty of them also received iliac autograft through a limited median incision at the lower tibia to repair their lateral tibial defects.After operation their ankle joints were fixated at 90?with piaster brace and cast for three months.The bone union,wound and the function of the ankles were observed after surgery.Results All the patients were followed up for an average of 16 months.The average bone union time was 14 weeks.No nonunion,screw loosening,broken plate,or infection of the wounds was found in this series.The excellent and good rate was 84.4% according to Mazur's ankle joint function scoring.Conclusion Indirect reduction and plate fixation through inferior fibula is a satisfactory technique in the treatment of distal tibiofibular fractures.

Objectives:To study the effect of Basen on the sensitivity of insulin in diabetes mellitus.Methods:Blood glucose,lipoprotein,insulin,C-peptide were assayed after and before the administration of Basen.Results:Levels of insulin,blood glucose,and C-peptide were lowered after four weeks administration of Basen,which changed contrarily to ISI.Conclusions:Basen has effects not only on lowering blood glucose but also on improving the insulin resistance.

This study is to investigate the effect of Euphorbia humifusa effective fraction (EHEF) on the CYP51 enzyme activity, the lanosterol content and the MEP, SUB gene expression of Trichophyton rubrum. Trichophyton rubrum was treated by EHEF for 7 days at 26 degrees C. The activity of CYP51 enzyme of Trichophyton rubrum in the cell membrane was determined by using ELISA kit, and the lanosterol content was investigated by using high performance liquid chromatography (HPLC), and the MEP, SUB gene expression of Trichophyton rubrum was detected with the reverse transcription polymerase chain reaction (RT-PCR) method. Results showed that EHEF can decrease the membrane CYP51 enzyme activity, and it also can accumulate the fungal lanosterol in a dose-dependent manner, and it also can decrease the gene expression of MEP and SUB. The antifungal mechanism of EHEF may be related to the inhibition on CYP51 enzyme activity, and to the effects on fungal cell membrane ergosterol biosynthesis. It may also play an antifungal effect by inhibiting the MEP, SUB gene expression of fungal proteases.

Objective: To explore relationship between sulfonylurea receptor gene polymorphism and type 2 diabetes mellitus in Chinese subjects. Methods: Polymorphism of exon 16-3T→C in SUR gene 1 in 155 type 2 diabetic subjects and 132 controls were assessed by restriction fragment length polymorphism. Results: Frequency of “C” allele and “CC” homozygous phenotype in type 2 diabetic subjects was higher than that in control group. Conclusion:Allele “C” stands for hereditary susceptibility to diabetes.

Objective: To investigate the levels of resisitin and C reactive protein, and their relationship with diabetic in patients. Methods: The levels of resistin and C reactive protein were determined in 62 diabetic patients and 42 control subjects. Results: The levels of C reactive protein and resistin were (5.62?0.80))mg/L,(37.43?11.52)?g/L,respectively, compared with control subjects(C reactive protein: (3.62?1.1) mg/L, Resisitin: (18.24?5.84) ng/ml),P

Objective Curcumin and MS-275,an inhibitor of histone deacetylase (HDAC),are promising anti-tumor agents. The aim of present study was to investigate the mechanisms of apoptosis induced by combined use of MS-275 in low dosage and curcumin in prostate cancer cell line DU145. Methods MTT assay was used to evaluate the lethal effect on DU145 cells by solitary use of MS-275 and or combined with curcumin. The changes in cell life cycle was detected by flow cytometry. The expressions of the survival signaling pathways were determined by Western blotting. Results Solitary application of MS-275 or curcumin may inhibit the growth of DU145 cells in a time and dose-dependent manner. The combination of MS-275 (1?mol/L) and curcumin (20?mol/L) exhibited obvious cytotoxic effect on cell viability,which was only 45.9% 48h after the combined treatment. Cell cycle assay showed that the combination of MS-275 and curcumin resulted in obvious appearance of sub-G1 phase in DU145 cells,implying that the cell apoptosis had been induced. The results of Western blotting showed that after treatment of MS-275 or curcumin singly,the phosphorylation level of Akt and ERK kinase declined slightly,however,when MS-275 and curcumin were used together,there appeared a prominent inhibitory effect on Akt and ERK kinase,indicated by a sharp decline of their phosphorylation level,and at the same time,the level of cleaved PARP,a hallmark of apoptosis,was increased in DU145 cells. Conclusion Combined use of MS-275 and curcumin may exert a synergistic cytotoxic effect on the viability of DU145 cells,and exhibit an inhibitory activity on Akt and ERK kinases to induce apoptosis.
