Objective To investigate the safety and efficacy of structured triglycerides in parenteral nutrition in elderly patients with acute biliary tract infection.Methods 62 elderly patients with acute biliary tract infection under conservative therapy were randomly divided into structured triglycerides (ST) group and medium-chain triglycerides plus long-chain triglycerides (MCT/LCT) group.Patients underwent parenteral nutrition for 5 days.Levels of hepatic enzymes,blood triglycerides,nitrogen balance,fasting blood insulin and glucose were compared between the two groups after 5 days of parenteral nutrition.Results There were no significant differences in levels of hepatic enzymes,blood triglycerides and fasting blood glucose between ST group and MCT/LCT group.Plasma total bilirubin (T-Bill) levels were increased in the two groups,and T-Bill level dropped faster in the ST group than in the MCT/LCT group after 7 days of parenteral nutrition(P< 0.05).The difference in total cholesterol level dropping was significant between ST group and MCT/ LCT group (P<0.05).The cumulative nitrogen balance for 5 days had significant difference between ST and MCT/LCT groups [(4.7-±-2.2) g vs.(2.8±0.7) g,P<0.05].STG group versus MCT/LCT group had less fluctuation of fasting blood insulin level after 1,4 and 7 days of parenteral nutrition.Conclusions In the acute phase of biliary tract infection in elderly patients,ST-based parenteral nutrition can provide energy and help maintain nitrogen balance,with a little fluctuation of fasting blood insulin level.Short-term nutritional support may have better tolerance in the liver and has little effect on the change of hepatic enzymes.

Objective To investigate the significance of anti-mutated citrullinated vimentin(MCV)an- tibody in rheumatoid arthritis(RA)and study the correlation among anti-CCP,other antoantibodies and clinical manifestations of RA.Methods Anti-MCV antibody was detected by enzyme-linked immunosorbent assay (ELISA)in 166 serum samples including 74 from RA(18 cases with early RA and 56 cases with late RA),50 from non-RA rheumatic diseases and 42 cases of healthy blood donors.At the same time,other antuoantibod- ies were detected by different techniques,and their clinical meaning was investigated with the corresponding clinical data.Results Anti-MCV was found in 78%(58/74)of RA.The sensitivity and specificity of Anti- MCV in RA were 78% and 95%.The positive and negative predictive value was 97% and 71%.The average cut off concentration of Anti-MCV was(552?380)U/ml in RA,(162?63)U/ml in non-RA and(63?46)U/ml in healthy control.Anti-MCV was strongly correlated to anti-CCP(r=0.502,P=0.000),then AKA(r=0.408)anti APF(r=0.369).No differences was found between Anti-MCV and other clinical/laboratory parameters(P>0.05). Conclusion Anti-MCV antibody may be a valuable diagnostic parameter for RA.Anti-MCV is more strongly correlated to anti-CCP than APE and AKA.It may not relate to disease activity and/or severity.

OBJECTIVETo introduce the application of pedicled anterolateral thigh (ALT) flap for total penile reconstruction and to investigate its feasibility and effect.
METHODSFrom May 2011 to May 2015, 12 male patients presented with absence of the penis or congenital malformation received phalloplasty with the pedicled ALT flap. Of them, the median age was 35 years old (range, 20-57 years). The size of the flaps ranged from 11 cm x 11 cm to 12 cm x 15 cm. 8 patients underwent urethra reconstruction with tube-in-tube flaps and other 4 patients with scrotal septal flaps. In this series, we performed one-stage urethral anastomosis in 4 cases and second-stage urethral anastomosis 6 months after the phalloplasty in 8 cases.
RESULTSAn acceptable reconstructed phallus was achieved in 10 patients. These flaps were primarily healed with satisfactory functional and cosmetic results. The reconstructed penis was completely necrosis because of the flap failure in one case. The distal half of the phallus was lost due to infection in one case. Both of them were treated with pedicled ALT flap from the other side. Reliable results were achieved. At a median follow-up of 1.5 year (range 1 to 4 years), 9 patients (90%) were fully satisfied with phallic cosmesis and size, and 4 patients who was married had successful sexual intercourse. 8 patients had normal urinate function. Fistula was developed in 2 patients (20%) which was treated with delayed repair at 6-12 months with local scrotal flaps.
CONCLUSIONSThe pedicled ALT flap can be simply used to reconstruct an entire penis as well as a urethra. It has several advantages including a less conspicuous donor site, greater bulk, better color match and no necessary for microsurgery.
