Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

Objective To observe the immunologic effect of lactoferrin on repeated respiratory infection(IRRI) in children.Methods Ninety-eight cases of IRRI were divided into two groups randomly.The control group (48 cases)were treated with routine therapy.The treatment group(50 cases) were treated with lactoferrin based on routine therapy for 2-3 months.T cell subgroup,immunoglobulin and complements were determined before and after treatment.Results Total effective rates in treatment group and control group were 86% and 22.9% respectively.The therapeutic efficacy in treatment group was significantly higher than that in control group(P

Objective To observe the effect of angiotensin-converting enzyme inhibitor(ACEI) on insulin sensiti-(vity) in dogs with acute myocardial infarction(AMI) after thrombolytic treatment. Methods Twenty dogs were made as AMI models and then underwent thrombolytic treatment.The dogs were divided into the control group(n=10) and the captopril group(n=10) randomly.Insulin,plasma glucose,erythrocyte insulin receptor(EIR),nitrogen(NO) and angiotensin Ⅱ(AT Ⅱ) were(detected) and insulin sensitivity index(ISI) was calculated.The changes of these values in the two groups were contrasted. Results After reperfusion for 120 min,in the control group,ISI and AT Ⅱgot much more rise while EIR and NO fell much more(P

Objective To perform a biomechanical study on and compare the stability of internal fixation with closed Kirschner wire in different spots from the epicondylus medialis to sulcus nervi ulnaris and epicondylus lateralis of humerus in the treatment of GartlandⅢsupracondylar fractures of humerus in children in order to provide basis for avoiding cubitus varus in clinic.Methods Twenty models of su- pracondylar fractures were made from ten humerus samples,then divided into two groups(group A and group B).They were fixed with closed Kirschner'wires.Ulnar Kirschner wire varied.In group A five spots were selected averagely from the epicondylus medialis to the sulcus nervi ulnaris.Kirschner wires entered from one of the five spots into another spot of humerus.In group B Kirschner wires entered defferent spots of humerus from the central spot of sulcus nervi ulnaris.Biomechanical tests were carried out,such as axial load,axial displacement,stress intensity,axial rigidity and anti-twisty ability.Forty-six children with Gart- landⅢsupracondylar fracture of humerus were treated and followed up for more than one year.Results In beth groups,with the angle of Kirschner wires and fracture side increasing,the strain and the vertical displacement decreased,the stress intensity and the axial rigidity increased,and the anti-twists ability was enhanced.There was statistic difference(P＜0.05).The follow-up of the 46 patients showed the elbow joint function recovered well with no cubitus varus malformation.Conclusion Internal fixation with closed Kirschner wires in sulcus nervi ulnaris from the epicondylus medialis and the epicondylns lateralis of humerus for GartlandⅢsupracondylar fracture of humerus in children has the advantages of enhancing bio- mechanical stability,effective prevention of secondary replacement of outlying black of the fracture and a- voidance of cubitus varus.It can be widely used clinically.

Objective To investigate the diagnosis and treatment of anticoagulation complication,heparin-induced thrombocytopenia (HIT),induced by low-molecular-weight heparin (LMWH) after joint replacement.Methods Retrospectively analyzed the clinical manifestations,treatment and prognosis of 4 patients after total knee arthroplasty (TKA) suffered from HIT induced by LMWH.Results The morbidity rate of HIT induced by LMWH was 0.3％(4/1376).Platelets were found less than 70 × 109/L after 4-9 d,minimum to 16 × 109/L.Different level of cardiorespiratory distress and lower extremity deep venous thrombosis all appeared.Once diagnosed,patients were immediately stopped using LMWH and replaced with argatroban,fondaparinux or rivaroxaban and warfarin.Deep vein thrombosis gradually disappeared and cured in 3 patients after treatment.One patient suffered cerebral hemorrhage and multiple pulmonary embolism,received craniotomy hematoma removal and decompressive craniectomy.But the patient didn't wake up after 1-month treatment,became a vegetative one.Conclusions HIT is rare but dangerous,which can result in deep vein thrombosis,pulmonary embolism,cerebral hemorrhage and other serious consequences.Early diagnosis and timely treatment can reduce the rate of disability and mortality.

OBJECTIVETo investigate the application of micronucleus test of buccal mucosal cells in monitoring the genetic effect of acrylonitrile in the population exposed to the acrylonitrile.

METHODSForty-one healthy male workers in a chemical factory in Shanghai were selected as the low concentration acrylonitrile exposed group while forty-seven healthy male workers in an acrylonitrile factory in Shanghai were selected as the intermediate concentration acrylonitrile exposed group. At the same time, thirty-one male workers who had no toxicant exposure and lived in the same community were selected as the control group. The micronucleus test in buccal mucosal cells and lymphocytes were used respectively for assessing the genetic damage status of these men.

RESULTSThe rate of micronucleus in buccal mucosal cells in both acrylonitrile groups (the low concentration group: 3.68% +/- 2.72%; the intermediate concentration group: 4.00% +/- 2.38%) was significantly higher than that in the control group (2.03% +/- 2.20%) (P < 0.05). The rate of micronucleus in the intermediate concentration group (4.23% +/- 3.34%) was significantly higher than that in the control group (2.48% +/- 1.46%) (P < 0.05). There was the correlation between the micronucleus test of buccal mucosal cells and the micronucleus test of the lymphocytes in the peripheral blood in the acrylonitrile exposed population (r = 0.299-0.359, P < 0.05).

CONCLUSIONThe micronucleus test of buccal mucosal cells replacing the micronucleus test of the lymphocytes in the peripheral blood can be used as one of the screening indexes in the surveillance of the genetic damage in the acrylonitrile exposed population.
