Results There was a significant difference in HGS,triceps skin foId thickness(TSF),mid-arm circumference(MAC),midarm muscle circumference(MAMC),Hb,albumin(Alb),serum crcatinine after 6 mortths of intervention compared with those before intervention. Conclusions Food composition table and foodstuff substitution method can obviously impwve the nutritional status for patients with diabetic nephwpathy undergoing peritoneal dialysis and increase the patients'diet compliance as well.

Objective To observe the influence of total glucosides of peony (TGP) combined with leflunomide on serum level of TNF-α,IL-8 in the patients with psoriatic arthritis(PsA) ,to evaluate its efficacy and safety and to preliminarily study its action mechanism .Methods The open clinical study was adopted .36 patients with PsA were treated by TGP combined with leflunomide for 12 weeks .at the same time 20 healthy control were selected .The double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) was adopted to detect the level of serum TNF-α and IL-8 before treatment and in 12 weeks after treatmention the two groups .The Psoriasis Area And Severity Index (PASI) was adopted as the main effective index and the Health Assessment Ques-tionaire(HAQ) was taken as the secondary effective index .The level of CRP ,ESR ,TNF-α,IL-8 before and after treatment were an-alysed .Results The serum TNF-α,IL-8 levels before therapy in the poriatic arthritis group were significantly higher than those in the normal control group(P<0 .05);after 12 weeks ,PASI ,HAQ ,serum TNF-αand IL-8 levels in the treatment group were signifi-cantly improved than those before treatment ,the difference had statistical significance(P<0 .01) ,and the serum TNF-α,IL-8 levels were similar to those in the healthy control group without statistical difference (P>0 .05) .Conclusion TGP combined leflunomide for treating PsA has better effect and better safety ,which could play the role by influencing serum TNF-α,IL-8 levels .

Objective To examine the effect of endotoxin on myocardial lipid metabolism and determine it′s possible mechanism Methods Sixty nine male Wistar rats (350 450g) were randomly divided into 2 groups: in vivo group and in vitro group In in vivo group endotoxin 0 1?g?kg -1 (small dose)or 1mg?kg -1 (large dose) was injected intrabdominally 3h after endotoxin administration the animals were anesthetized Heart was excised and passively perfused in a Laugendorff apparatus with oxygenated Krebs Heuseleit buffer at 37℃ Non esterified fatty acids (NEFA)and triacylglycerols(TAG) were used as energy supplying substance when the isolated heart had been stabilized for 15min NEFA or TAG was slowly added to the perfusate circuit 1 ml of perfusate was drawn every 10 min until the end of experiment (80 min ) for determination of the effects of endotoxin on NEFA or TAG oxidation and utilization by isolated heart At the end of experiment heart was harvested and frozen for measurement of myocardial lipids and lipoprotein lipase activity In in vitro group endotoxin was added to perfusate (1mg/ml) after the heart was excised and passively perfused In control group endotoxin was replaced by normal saline Results Large dose of endotoxin administered in vivo decreased NEFA oxidation rate by 30% in perfused isolated heart and caused increased accumulation of lipid in myocardial tissue By contrast endotoxin administered in vitro increased oxidation rate of TAG accompanied by an increase in myocardial lipoprotein lipase activity Administration of endotoxin in vivo and in vitro also caused accumulation of various exogenous lipids in myocardium in both NEFA and TAG perfused heart Conclusions This study shows that endotoxin has a significant effect on myocardial lipid metabolism The effect of endotoxin could be either direct or indirect according to the different lipids available

Objective To investigate the clinical significance of PET-CT to diagnose breast cancer and the axiUary lymph nodes metastasis. Methods 40 patients with breast cancer performed PET-CT were enrolled in the research. Qualitation the primary tumor and accuracy of PET-CT were evaluated on pathological results and compared with axillary lymph nodes dissection. To analyzed the concordance of the size of primary tumor on pathological result with B-mode ultrasonic and PET-CT and the correlation with the SUV. Results The accuracy, sensitivity and specificity of PET-CT in identifying breast cancer were 95%, 94%, 100%. The accuracy, sensitivity and specificity of PET-CT based on the situation of the axillary lymph node dissection were 88.2% 89.2% 83.3%. A significant association was found between tumor weiweihong and PET-CT, furthermore it had not association with SUV. Conclusion The diagnosis of PET-CT in identifying breast cancer and the axillary lymph node metastasis basically conforms to pathology. It possesses high sensitivity and specificity especially in identifying the size of the primary lesion. It offers a beneficial method to determine the axillary lymph node dissection and reasonable therapeutic regimen.

ObJective To locate the cysteine-rich domains(CRD) of murine 4-1BB binding to its natural ligand. Methods A serial soluble extracellular CRDs of routine 4-1BB and 4-1BBL fusion proteins was constructed and prepared. The binding of purified 4-1BB-Igs to 4-1BBL and 4-1BB monoclonal antibody were tested using ELISA assay and Western blot analysis. Blocking experiment with 4-1BBL and 4-1BB mon-oclonal antibody was performed by ELISA assay. Results All truncated overlapped proteins containing ex-tracellular CRD Ⅱ of murine 4-1BB were able to bind to 4-1BBL by ELISA assay, excepting the CRD Ⅰ do-main alone. A 4-1BB monoclonal antibody proved to block the interaction of 4-1BB and 4-1BBI, was also able to bind to CRD Ⅱ. Conclusion Murine 4-1BBL whose specificity was mapped to CRD Ⅱ of 4-1BB ex-tracellular region with a possible conformational structure.

[Summary] A total of 352 pregnant women were selected in Affiliated Hospital of Qingdao University. Serum levels of TSH and FT4 were determined and pregnancy outcome were observed in all subjects. According to the standard of American Thyroid Association(ATA) published in 2011 and the Chinese Guideline of Gestation Thyroid Disease published in 2012, the subjects were grouped into control(0. 1≤TSH≤2. 5 mIU/ L), observation(2. 55. 17 mIU/ L)during first-trimester(T1)and control(0. 2≤TSH≤3. 0 mIU/ L), observation(3. 05. 22 mIU/ L) during second-trimester(T2). The results showed that the rupture of membranes, preterm labor, and total obstetrical adverse events in the observation group were significantly higher than those in control group during T1(all P<0. 05), no statistical significance between control group and treatment group. The rupture of membrances in the observation group was significantly higher compared with control group during T2 ( P < 0. 05), no significant difference in other adverse pregnancy outcomes between these two groups. Compared with control group during T1, the proportion of adverse pregnancy outcomes in observation group during T1 was significantly increased(P<0. 05). The elevated TSH is one of the risk factors for the increased incidence of adverse pregnancy outcomes at the first half of pregnancy, especially during T1. L-T4 treatment reduces the incidence of adverse pregnancy outcomes.
