ABSTRACT
Objective To evaluate smooth muscle protein of 22 kDa (SM22) in the diagnosis of acute intestinal ischemia.Methods 96 healthy adult SD rats were evenly divided into experimental group and control group,with each group subdivided into 6 subgroups,subject respectively to superior mesenteric artery ligation or sham operation.The venous blood samples were extracted from each group rats' right heart atO.5,1,2,4,8,12 h after the operation,for SM22 testing and small intestines tissues for direct immunofluorescence staining of SM22.Results The serum SM22 concentration reached a peak at 4 h (265 ± 15) mg/L,then gradually decreased (P ＜ 0.05).The I-FABP was mainly expressed in the epithelium of intestinal mucosa.During the 4 hours of intestinal ischemia,The number of SM22 positive particles did not change.After 4 hours,the number of SM22 positive granules had gradually decreased compared with the control group (all P ＜ 0.05).Conclusion SM22 mainly exists in the smooth muscle of intestinal,during the ischemic necrosis of the intestinal muscle layer SM22 leaks into blood stream,resulting in high serum levels of SM22 facilitating early diagnosis of acute intestinal ischemia.
ABSTRACT
A case of several ambushed bicuspoid supernumerary teeth in the premolar area was reported.The size,shape and the ratio of crown to root of the supernumerary teeth are similar to those of the premolar.The abnormity of tooth germ division and proliferation may lead the supernumerary teeth.
ABSTRACT
Objective To analyze the clinical and laboratory characteristics of systemic lupus erythematosus (SLE) in children. Methods Fifty-three inpatients, 5 boys and 48 girls with SLE, who aged from 7 to 14 years with a median age at 12 years, were enrolled into this study. A retrospective study was carried out to assess the clinical and laboratory features of these pediatric patients. Results The ratio of male to female patients was 1:9.6. Skin eruption was the most common initial manifestation (41.51%), followed by fever (20.75%) and arthralgia (20.75%). Systemic involvement was common, and 84.90% of these patients had hematological abnormalities, 60.38% renal involvement, 18.87% nervous involvement. The most common manifestation of hematological, renal and nervous involvement was anemia, proteinuria and seizures, respectively. Among the immunologic parameters tested, anti-nuclear antibody showed the highest positivity rate of 90.57%, followed by anti-dsDNA with a positivity rate of 67.92%. There was no significant difference between the male and female patients in the age of onset, SLEDAI score at admission and discharge, duration of hospitalization or the dose of corticosteroid used initially and at the discharge. Conclusion The manifestations of pediatric SLE are various, and multisystem involvement is common in these patients. Early diagnosis and active treatment might benefit the prognosis of pediatric SLE.
ABSTRACT
Objective To evaluate the microscopic characteristics of hepatocellular carcinoma (HCC) invasion,and to provide the reference for GTV-to-CTV expansion. Methods From January 2002 to January 2006,149 HCC patients treated by surgical resection were included. The pathologic slices and clinical data were reviewed, including the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage, histology grade, serum alpha-fetoprotein (AFP), platelet count and the degree of liver cirrhosis. The distance between the tumor capsule and the invasion was measured by 2 senior pathologists. Results of the 149 patients evaluated,79(53.0%) patients presented micro-invasion ranged between 0.5-4.0 mm. The recurrence rate was higher in patients with micro-invasion than those without (44% vs 29%, P=0.047). The invasion extent was positively relative to the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage,histology grade and AFP,while negatively relative to the platelet count. A score system was established according to five predictors of tumor size, capsule status, portal vein invasion, AFP and platelet count. The invasion distance below 2 mm was in 96.6% patients who had≤2 points and only 83.3% for those with 2 points. Conclusions For HCC patients,the invasion extent is relative to the tumor size,cap sule status,portal vein invasion, AFP and platelet count. These 5 predictors could be potentially used as a score system for GTV-to-CTV expansion.
ABSTRACT
Objective To observe the efficacy of Yinxieling Tablets(YT) for the treatment of psoriasis vulgaris(PV),and to explore its therapeutic mechanism.Methods Forty-eight PV patients were equally randomized into two groups.The two groups received external application of Fubirun ointment.Additionally,the treatment group received oral use of YT(mainly composed of Radix Rehmanniae,Radix Angelicae Sinensis,Radix Paeoniae Rubra,Rhizoma Chuanxiong,Radix Arnebiae seu Lithospermi,Rhizoma Curcumae,Herba Chloranthi Spicati,Rhizoma Smilacis Glabrae,Fructus Mume,Radix Glycyrrhizae,etc.),and the control group received oral use of Acitretin Capsules.Four weeks constituted one treatment course,and the treatment in both groups lasted 2 courses.After treatment,the relief of symptoms and signs in both groups was evaluated by Psoriasis Area and Severity Index(PASI) scoring,the side effects were monitored,and serum interferon-gamma(IFN-?)level was measured.Results(1) At the end of the first treatment course,the therapeutic effect in the treatment group was better than that in the control group(P0.05).(2) After one treatment course,serum IFN-? level was decreased in both groups(P0.05).(3) The adverse effects of dry skin,abdominal discomfort,dry lips and abnormal hepatic and renal function were not obvious in the treatment group(P
