A new instrument was devised to determine the angle between the long axis of the neck and the bicondylar plane of the femur.The superior border of the neck was first determined by a line connecting the two superior ends of the junctions between “head and neck,”and “neck and great trochanter” respectively;the inferior border being determined in similar way.(2)The angle between the superior border of the neck and the bicondylar plane and (3) the angle of the inferior border with the same plane were then measured.(4)The average of the two angles was taken as the angle of torsion of the neck. Three hundred femurs of both sexes were measured.It was found that the angle of torsion of the neck in the adult male is 7.88?,and that in the females is 9.37?.The average value is 8.66?. It was discussed how the angle of torsion in the neck is formed,perhaps it results from the pulling effect of the muscles.

Objective To investigate the effect of metformin on thyroid hormone and thyrotropin(TSH) in diabetic patients without thyroid hormone replacement.Methods Serum levels of free T3(FT3),free T4(FT4),total T3(TT3),total T4(TT4) and TSH were measured in diabetic patients with or without metformin therapy and the relationship between TSH and metformin was analyzed.Results There were no significant differences in serum FT3(4.65±0.68 vs 4.59±0.67 pmol/L),FT4(17.88±3.26 vs 17.75±2.85pmol/L),TT3(1.79±0.42 vs 1.77±0.38nmol/L),TT4(107.9 ±22.1 vs 109.2±22.1nmol/L) and thyrotropin(ln TSH:0.49±0.83 vs 0.47±0.87 mU/L) between diabetic patients taking and not taking metformin.Conclusions In diabetic patients without thyroid hormone replacement,metformin does not suppress serum TSH

BACKGROUND:Currently, bioactive glass and polylactic acid have been used in clinical dentistry and plastic surgery; however, their therapeutic outcomes are not satisfactory, because the material properties have some limitations. OBJECTIVE:To explore the cytocompatibility of oxygen plasma-treated polylactic acid and bioactive glass guided bone regeneration membrane. METHODS:Bioactive glass and polylactic acid were used as the basic materials to prepare polylactic acid membrane, polylactic acid and bioactive glass composite membrane and oxygen plasme-treated polylactic acid and bioactive glass composite membrane, al of which were used to culture MG63 cels. Cel adhesion rate, cel proliferation rate and alkaline phosphatase activity of MG63 cels on these three kinds of membranes were observed. RESULTS AND CONCLUSION: With the growth of time, in these three groups of membranes, the cel adhesion rate and cel proliferation rate were al significantly increased. Alkaline phosphatase activity showed a decreasing trend after the first increase, and reached its peak at the 7thday of culture. The cel adhesion rate and cel proliferation rate in oxygen plasma-treated polylactic acid and bioactive glass group were significantly higher than those in the other two groups, while the cel adhesion and proliferation rates in polylactic acid and polylactic acid and bioactive glass groups were similar. At the 3rd day of culture, the alkaline phosphatase activity in the polylactic acid and bioactive glass group and oxygen plasma-treated polylactic acid and bioactive glass group was significantly higher than that in the polylactic acid group. At the 7th and 14th days, there was no significant difference in the alkaline phosphatase activity among these three groups. These results show that oxygen plasma-treated polylactic acid and bioactive glass composite membrane has good biocompatibility, which can better promote cel adhesion, proliferation and matrix secretion from osteogenic cels.

Objective To investigate the factors in association with colorectal disorders in adult recipients of liver allograft. Methods A retrospective cohort study was carried out with clinical, microbiological and management data regarding diarrhea in 218 adult recipients of liver allograft from Jan. 2003 to Dec. 2006. Results Of the 218 patients, 68(31.2%) of them, who did not history of ulcerative colitis, were found to have diarrhea after orthotopic liver transplantation. Among these 68 patients, diarrhea was probably caused by administration of immunosuppressive agents in 35 cases (51.4%), in 12 cases (17.6%) diarrhea was antibiotics associated, and in 5 cases (7.4%) it was due to intraperitoneal infection. The other pathogenic factors included fungal infection in 3 cases (4.4%), cytomegalovirus infection in 3 cases (4.4%), Roux-en-Y choledochojejunostomy in 8 cases (11.8%) and some other unknown problem related in 2 cases (2.9%). Diarrhea occurred soon after transplantation in most cases. Of the 68 patients, the symptom of diarrhea occurred in the first 2 months in 45 cases (66.2%), and in the next 4 months in 23 cases (33.8%), i.e. the symptoms occurred 5-180 days after transplantation. Conclusion Immunosuppressive agents, antibiotics, fungal infection and cytomegalovirus infection are the top four common causes of diarrhea after orthotopic liver transplantation. The outcome is good with appropriate conservative management.
