Proteomics is a new field of studying the protein and its dynamic axiom of transmutation in cells.In recent years,it has been used as a powerful tool in research of life science.Proteomics functions as a new method to investigate the pathogenesis of diseases.In this article,the up-to-date information of proteomics technologies in autoimmune disease research are reviewed.

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.

Objective To carried out rat as deep inferior epigastic perforator (DIEP) flap necrosis model,to reveal the continuous blood fluid change in process of flap necrosis.Methods Seven SpragueDawley rats of male were used.The designed DIEP flap model was pedicled on the right-sided cranial perforator.Near-infrared fluorescent angiography was performed using SPY imaging system pre-and-aft operation and all angiography videos were compared and analyzed.Results Using SPY imaging system could observe the process of the blood fluid scattered from perforator through choke anastomoses to next vascular territories in living body.The study could clearly observe sequence change of blood fluid pr-and-aft operation,which could give the important information in revealing the reason of necrosis in DIEP flap.Cross-midline traffic vascular sparse and eventually could no longer wear through the contralateral abdominal wall vessel area and open in the region of lateral thoracic vascular occlusion of blood vessels to reach the flap to the far left side,and showed no blood flow in the dark zone.Conclusion The reasons of necrosis of contralateral distal zone of the flap model,are the choke anastomoses across the midline to the contralateral side appeared small,less intensity and the blood supply to contralatral distal zone should through twice choke anastomoses.

Objective To research whether the polyunsaturated fatty acids (PUFAs) level in prenatal and postpartum women af‐fect the incidence of postpartum depression .Methods 102 eligible and voluntary parturients of full‐term normal delivery were se‐lected and the serum specimens before labor and on postpartum 3 ,42 d were respectively collected for detecting serum PUFAs lev‐els .The perinatal depression related factors questionnaire and the Edinburgh Postnatal Depression Scale (EPDS) were filled in and the scores were evaluated for analyzing the incidence of postpartum depression .Results Among 102 pregnant women and parturi‐ents ,the postputum depression appeared in 28 cases with the positive rate of 27 .5% .The incidence rate of postpartum depression in the eicosapentaenoic acid (EPA) low values group and the docosahexaenoic acid (DHA) low and medium values groups was higher than that in the high values groups ;the incidence rate of postpartum depression in the arachidonic acid (AA) high value group was the higher than that in the low value group .Conclusion The lower the EPA and DHA levels ,the easier to develop depression .

Objective To evaluate the technique and outcome of arthroscopic reconstruction of posterior cruciate ligament(PCL)with preservation of the remnants.Methods From January 2006 to January 2009.16 knees in 16 patients with PCL tear were verified with arthroscopy.All the damaged PCL were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy without remove of the remnants of PCL.Endo-button and Bio-absorbabh interference screw were used for direct anatomic fixation of the reconstructed ligament.Results No severe complication occurred in early stage after operation in the 16 patients.All of them were followed up from 4 to 14 months with an average of (7.4±2.1)months.Lysholm score was remarkable improved from mean(61.3±8.7)preoperative scores to mean(91.7±6.3)scores at the latest follow up(P＜0.05).Furthermore,there was a significant improvement in IKDC scofe from abnormal (grade C)in 9 knees and severely abnormal (grade D)in 7 knees preoperatively to normal(grade A)in 11 knees,nearly normal(grade B)in 5 knees at the follow up.All of the 16 patients returned to the same sports level before injury.Conclusion Arthroscopic reconstruction of PCL with preservadon of the remnants has advantages of minimal inmmrticular interference,and potential facility to revagculization and reinnervation of the reconstlucted ligament.

Objective To discuss the relationships between serum uric acid levels and clinical stages,cognitive dysfunction in parkinson' s disease (PD).Methods Sixty patients of PD were enrolled,and their history,detailed physical examination UPDRS Ⅲ scale and mini-mental state score (MMSE) scale were performed to determine the Hoehn-Yahr stage of patients.At the same time 52 cases of healthy person were collected from the Health Examination Centers whose age,sex,and education matched with PD group as control group.The levels of serum uric acid in the two groups were examined and compared.Results The serum uric acid levels in PD group were significantly lower than those in normal control group((262.4 ±85.2) μmol/L vs (357.6 ±73.3) μmol/L) (t =1.013,P =0.005) ;There was no level correlation between different Hoehn-Yahr stage period of PD group (r =0.143,P ＞ 0.05) ; There was no significant difference on serum uric acid levels between subgroup of PD patients (F =1.014,P =0.06) ;The M MSE score between PD group and normal control group had no significant difference (26.12 ± 2.87 vs 28.32 ± 2.17) (t =1.970,P =0.073).Conclusion Low level of the serum uric is likely to be a risk factor for PD,but cannot be used to assess the severity of disease and MMSE scale used to determine the cognitive impairment in PD is not sensitive enough.

Objective To explore the clinical characteristics and emergency treatment for type 1 diabetes(T1DM) and diabetes ketoacidosis(DKA) in children under 5 years old.Methods Twenty-one children under 5 years old with T1DM with 10 years were retrospecti-vely reviewed.The onset situation,clinical feature and treatment of DKA were analyzed.Results The cases of little children diabetes might not have typical symptoms.The positivity of islet antibody was lower.High morbidity of DKA was found in little children and DKA was often caused by infection.Conclusions Infection may be involved in the onset and progress of childhood T1DM.Emergency treatment for DKA may involve the injection of small dose insulin,correction of the disorder of water and electrolysis and regulation of acid-base.

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.
