ABSTRACT
Objective:To discuss the clinical characteristics,diagnosis and treatment experience of a case of lateral ectopic thyroid.Methods:The patient with lateral ectopic thyroid was diagnosed by thyroid color ultrasound and single-photon emission computed tomography(SPECT)-CT examination.The right thyroidectomy and the thyroid tissue in cervical section Ⅳ of the patient were removed by received the operation.The pathological examination after operation was performed.The daily usage of euthyrox after operation was 50 μg.Results:The patient recovered well,who accepted 10 months follow-up with normal life and stable condition,and had no recurrence and metastasis.Conclusion:The mechanism of lateral ectopic thyroidy is not clear yet,the surgical treatment can result in good effectiveness and better prognosis.
ABSTRACT
Objective To study the effect and mechanisms of TW-37 on cell proliferation,apoptosis,invasion and angiogenesis in pancreatic cancer cells in vitro and further explore the potential mechanism.Methods BxPC3 and HPAC cells were pretreated with TW-37 using untransfected or transfected with NF-κB p65 cDNA(p65 cDNA)or NF-κB p65 siRNA(siRNA-p65)cells as controls.Cell viability was determined by MrTT assay.Cell apoptosis was assessed by enzyme-linked immunosorbent assay (ELISA).Cell invasion and angiogenesis was detected by Transwell and endothelial tube formation assay of HUVECs.ELISA assay was used to measure the activity of NF-κB,and its target proteins of MMP-9 and VEGF were detected by western blot.Results TW-37 suppressed cell growth and induced apoptosis (A405:1.29 ± 0.21 vs 0.09 ± 0.01,1.07 s0.18 vs 0.08 ± 0.01),inhibited NF-κB activity and protein expression of NF-κB p65,VEGF and MMP-9(all P ＜0.05)in a dose-and time-dependent manner.The number of cells that invaded across the matrigel in the transwell chamber was (46.7 ±5.24) and (10.3 ± 1.26)/×200 in BxPC3 control and 0.75 μmol/L TW-37 group (P=0.001).The number of tube formation was (39.4 ±4.36) and (7.84 ± 1.25)/×200,(P =0.001).NF-κB activity was increased by p65 cDNA transfection,and decreased by TW-37 treatment in both of the two cell lines (P ＜0.05).However,NF-κB activity was decreased by p65 siRNA transfection,and greatly decreased by TW-37 treatment in both two cell lines (P ＜0.05 or P ＜0.01).Transfection of p65 cDNA did not significantly affect cell apoptosis.Transfection of p65 siRNA increased cell apoptosis,and greatly increased by TW-37 treatment in both two cell lines (all P ＜ 0.01).Conclusions TW-37 could inhibit the proliferation,invasion and angiogenesis in pancreatic cancer cells by regulating NF-κB signal pathway.
ABSTRACT
Objective To investigate the level of urinary TGF-β1 and evaluate its clinical significance in patients with chronic nephritis.Methods 22 healthy people and 40 patients with chronic nephritis were selected,the levels of urinary TGF-β1 were measured by RT-PCR and ELISA.Results Urinary TGF-β1 were significantly increased in Mesangial Proliferative Glomerulonephritis (76.44± 24.29 ng/mmol.Cr vs 31.53 ± 11.59 ng/mmol.Cr,P<0.01);Focal Glomerular Sclerosis (65.07±20.59 ng/mmol.Cr vs 31.53±11.59 ng/mmol.Cr,P<0.01)and IgA Nephritis (67.01±21.95 ng/mmol.Cr vs 31.53±11.59 ng/mmol.Cr,P<0.01),comparing with normal group.Conclusion The levels of urinary TGF-β1 could be a predictor in reflecting the sate of renal diease,estimating pathological type,diagnosing the renal diease and observing the therapeutic effects.
ABSTRACT
Objective To investigate the best time to establish the enteral nutrition (EN) in elderly patients with se?vere craniocerebral diseases. Methods Eighty-one elderly patients were divided into groups A, B and C. The EN support were given 24 h, 25-48 h, and 49-72 h after surgery. Changes of serum biochemical indexes, complications and GCS score were detected and statistical analysed. Results The serum levels of albumin and hemoglobin were significantly increased in group B than those of group A and group C. The total number of lymphocytes was significantly higher in group A and group B than that of group C (P<0.05). The amount of diarrhea was significantly fewer 7-day after operation in group B than that of group A (3.6%vs 26.9%). The amount of stress ulcer was significantly fewer in group B than that of group C (0 vs 22.2%). The amounts of lung infections (10.7%vs 38.5%) and stress ulcer (3.6%vs 25.9%) were significantly fewer 14-day after oper?ation in group B than those of group A. The scores of GCS were significantly higher 14-day after operation in group B than those of group A and group C (10.2±1.3 vs 9.5±1.2 vs 9.4±1.2, P<0.05). Conclusion The establishment of EN support 25 to 48 hours after surgery may meet the need of nutritional and metabolic support, reduce complications, be conducive to the consciousness recovery in elderly patients with severe craniocerebral diseases.
ABSTRACT
Objective To analyze the safety and effectiveness of using lumbar drainage (LD) in patients with subarachnoid hemorrhage (SAH).Methods Data from 44 patients with SAH were collected.Of these patients,the LDs group consisting 19 patients in whom a lumbar drain had been placed for cerebro-spinal fluid (CSF) drainage,whereas the control group was composed of 25 patients who received no form of CSF drainage or treated solely with an external ventricular drainage (EVD).Incidence of new cerebral infarction of the two groups was measured on sequential CT and complications of LDs group.Results This retrospective review demonstrated a statistically significant beneficial effect in LDs group on CT,reducing the incidence from 32％ to 5％.A similar degree of benefit was observed in two group patients with hydrocephalus.Complications with lumbar drains were rare and yielded no permanent sequelae.Conclusion With rare complications and definite safety,LDs are effective to reduce vasospastic cerebral infarction of SAH patients when appropriate patient selection and good technique are employed.
