Compared with control group(20 cases of thyroid follicular adenoma,TFA),the higher expressions of S-100 in HT(139.38±5.92 vs 59.47±11.69) and GD(119.42±14.48 vs 59.47±11.69) were observed respectively(p< 0.001).The increased positive expressions of CD83 which is known as a marker of mature and activated DCs in HT(22.58±13.96 vs 5.19±8.08) and GD(29.92±14.43 vs 5.19±8.08) were also found respectively(p<0.001). Serum TPO antibody(TPO-Ab,67.3±11.6%) and Tg antibody(Tg-Ab,59.8±10.1%) in HT were higher than those in GD(28.4±5.7%,23.1±4.9%) and TFA(6.1±3.4%,7.2±4.6%)(p<0.01).Serum TR-Ab in GD(16.3 ±5.6 U/L) was higher than those in HT(4.8±2.3 U/L) and TFA(2.5±1.2 U/L)(p<0.01).Our findings suggest that the high expression of DCs' markers may be related to the pathogenesis of HT and GD.The upregulation of both the number and the matured functions of DCs,may lead to present more antigens and to produce more auto-antibodies(such as Tg-Ab and TPO-Ab in HT,TR-Ab in GD),which may be involved in pathogenesis of the autoimmune thyroid diseases.Cellular & Molecular Immunology.2004;1(5):378-382.展开更多

Gastrointestinal schwannomas are uncommon stromal tumors of the intestinal tract and, in particular, rectal schwannomas are extremely rare. In fact, it is well established that schwannomas appear more frequently in the stomach and in the small intestine, while location in the colon or in the rectum is uncommon. Reading the literature, only few cases of rectal schwannoma have been reported. Their diagnosis is confirmed by the immunohisto chemical panel(S-100 protein). When these tumors are located in the colon and in the rectum, radical excision with wide margins is mandatory, due to their tendency to recur locally or become malignant, if left untreated. In the present study, we describe a case of a rectal schwannoma occured in a 72-year-old man, presented as a small polypoid lesion, which was successfully removed in toto by hot-biopsy, during the same endoscopy, due to the dimensons. No recurrence of the lesion was observed after 6 mo of follow-up.展开更多

The patients in the two groups were given routine drugs for conservative treatment. On this basis, the patients in the observation group were given HUK. NSE and S-100 protein before treatment, 3, 7, 14, and 28 d after treatment in the two groups were compared. TCD was used to detect the cerebral hemodynamics. NIHSS and BI were used to evaluate the improved degree of neurological function and daily living activities before treatment, 1 and 3 months after treatment.Results: NSE and S-100 protein 3, 7, 14, and 28 d after treatment in the observation group were significantly lower than those in the control group (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the two groups was significantly elevated (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the observation group was significantly higher than that in the control group (P<0.05). NIHSS and BI scores 1 and 3 months after treatment in the observation group were significantly superior to those in the control group (P<0.05).Conclusions: HUK can effective reduced the brain tissue injury in patients with acute cerebral infarction, and promote the recovery of neurological function, with an accurate efficacy.展开更多

Methods Forty patients (age>65 yr) undergoing total hip replacement were assigned to two groups, randomly. In one group, the mean arterial pressure was decreased about 30% by sodium nitroprusside. In another group, the MAP was set constant as control. Serum values of S-100 were determined preoperatively and 0 2 h and 24 h postoperatively. Neuropsychological tests (Mini-Mental State Examination MMSE) for detecting POCD were performed preoperatively and the 4th day after the operation. A decline of more than 2 scores in MMSE results was regarded as POCD. Results According to our definition, 7 patients had POCD. There were no significant differences in MMSE test in two groups (P>0.05). Those patients had POCD showed higher serum concentrations of S-100 than those without POCD, especially at 0, 2 h postoperatively (P<0.05). Conclusion Nitroprusside induced hypotension would not impair cognitive function in old patients after total hip arthroplasty. S-100 appears to be suitable in the assessment or incidence of cognitive dysfunctions postoperatively.展开更多

NSE and S-100 protein before treatment, 3, 7, 14, and 28 d after treatment in the two groups were compared. TCD was used to detect the cerebral hemodynamics. NIHSS and BI were used to evaluate the improved degree of neurological function and daily living activities before treatment, 1 and 3 months after treatment.Results: NSE and S-100 protein 3, 7, 14, and 28 d after treatment in the observation group were significantly lower than those in the control group (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the two groups was significantly elevated (P<0.05). The blood flow rate of left vertebral artery, right vertebral artery, and basilar artery after treatment in the observation group was significantly higher than that in the control group (P<0.05). NIHSS and BI scores 1 and 3 months after treatment in the observation group were significantly superior to those in the control group (P<0.05).Conclusions: HUK can effective reduced the brain tissue injury in patients with acute cerebral infarction, and promote the recovery of neurological function, with an accurate efficacy.
文摘The anterior pituitary gland regulates growth,metabolism,and reproduction by secreting hormones.Folliculo-stellate cells(FSC)are non-endocrine cells located among hormone-producing cells in the anterior pituitary glands,but little is known about the exact roles of those cells.Although,with their net organization,they seem to have an important role in the hormonal cells regulation and maintenance.In this work,the first ever made in this area,33 pituitaries of three groups of mice(18 wild type[WT],11 genetically obese[OB]and 4 under a high-fat diet[HFD])were studied in order to determine if there was any relation between the number of FSC and alterations of the basal metabolism in each group of mice.For that,immunohistochemical staining using the S-100 protein was used and also the Image-J software,to calculate the percentage of FSC present in each sample.The authors found that,although there wasn’t any significant difference between WT and OB mice,the group of HFD mice tend to have substantially higher percentage of FSC than the mice from other groups.This might suggest some yet unknown link between diet,precisely with a high-fat diet,and the presentation of FSC in the anterior pituitary.
文摘Malignant Gastrointestinal Neuroectodermal Tumor (GNET) is a recently described rare malignant neoplasm, resembling “clear cell sarcoma of tendons and aponeuroses” morphologically, immunohistochemically and molecular pathologically. We will describe a case of soft tissue sarcoma located at right cervical region of a 9-year-old male patient, mimicking malignant GNET, which can be considered as extragastrointestinal counterpart of this tumor. These tumors have poor prognosis. This is unique, possibly the first case of a soft tissue sarcoma resembling GNET.
文摘Objestive To investigate the effects of nitroprusside induced hypotension on cognitive function after total hip replacement and the serum S-100 level in reflecting postoperative cognitive dysfunction (POCD). Methods Forty patients (age>65 yr) undergoing total hip replacement were assigned to two groups, randomly. In one group, the mean arterial pressure was decreased about 30% by sodium nitroprusside. In another group, the MAP was set constant as control. Serum values of S-100 were determined preoperatively and 0 2 h and 24 h postoperatively. Neuropsychological tests (Mini-Mental State Examination MMSE) for detecting POCD were performed preoperatively and the 4th day after the operation. A decline of more than 2 scores in MMSE results was regarded as POCD. Results According to our definition, 7 patients had POCD. There were no significant differences in MMSE test in two groups (P>0.05). Those patients had POCD showed higher serum concentrations of S-100 than those without POCD, especially at 0, 2 h postoperatively (P<0.05). Conclusion Nitroprusside induced hypotension would not impair cognitive function in old patients after total hip arthroplasty. S-100 appears to be suitable in the assessment or incidence of cognitive dysfunctions postoperatively.
