Objective To evaluate the effect of medicial and surgical treatment for juvenile hyperthyroidism.Methods Ortapazole was administ rated separately in drug therapy group for 1.5-2 years.Bilateral subtotal thyroidectomy was done in surgical therapy group.Results In drug therapy group,effective rate was 60 percent in 6 months and 70 percent in one year.Recurrence rate was 40 percent after drug withdrawal in 2 years curative rate was 60 percent.In surgical therapy group,the average stay in hospital was 16 days.There was no nerve injury,parathyroidal hypofunction,thyroid crisis or hypothyroidism complications,with 100 percent curative rate after 2 years′ followup.Postoperative growth and development were normal.Conclusions Surgical treatment may be suitable for those who have no response to drug therapy,with recurrence after drug withdrawal,whose compression symptom was obvious,with moderate and severe hyperthyroidism or those who could not take medicine persistently.Bilateral subtotal thyroidectomy applied in juvenile hyperthyroidism could achieve quick and better recovery,and has no influence on the juvenile growth and development.

An experimental model of reproducible focal cerebral contusions in rats was made by a free-drop impacting right hemisphere. The expression of fibronectin and its mRNA after cerebral contusion were detected respectively by immunohistochemical staining and in situ hybridization. Results indicated that the expression of fibronectin and its mRNA increased after injury, and there existed a relationship between increased fibronectin and its mRNA and different intervals after brain injury. It is inferred that the expression of fibronectin and its mRNA can be used for timing of brain injuries and distinguishing antemortem and postmortem brain contusions.

Umbilical metastases from intraperitoneal malignancies are universally referred to Sister Mary Joseph's nodule (SMJN).The most frequent primary sites include the stomach and ovaries. SMJN caused by colon cancer is very uncommon. Likewise, carcinoma of the right side colon metastasizing to inguinal lymph nodes is considered almost impossible. To the best of our knowledge, no report of right side colon cancer synchronously involving both the umbilicus and inguinal lymph nodes is available. We present a case of right side colon cancer(RSCC) metastasizing to the umbilicus and inguinal lymph nodes, which was confirmed by pathology and immuohistochemistry.

Objective To investigate late stent malapposition or vessel remodeling post chitosan/heparin layer-by-layer self assembly coating stent (LBL) implantation in porcine.Methods A total of 32 stents [ bare metal stent ( BMS,n =9),sirolimus-eluting stent ( SES,n =11 ) and LBL ( n =12 ) ] were implanted into coronary arteries of 16 porcine.Intravascular ultrasound (IVUS) was performed immediately after stenting and at 1 month after stenting to measure vessel area (VA),stent area (SA) and lumen area (LA).Neointima area (NA) was measured at 1 month post stenting by IVUS to detect signs of stent malapposition and to determine remodeling index (RI). Histopathology was performed at 1 month post stenting to observe vessel wall structure and stent malapposition status.Results No sign of stent malapposition was detected,VA and SA/LA were similar among groups immediately after stent implantation.At 1 month follow-up,none of three groups showed stent malapposition.VA,SA,NA and LA were ( 7.30 ±0.77),(6.83 ±0.76),(1.40 ±0.96) and (5.43 ±0.88)mm2 in LBL group,(7.13 ±0.69),(6.63 ±0.71 ),(0.28 ±0.35) and (6.34 ±0.89)mm2 in SES group,(7.48 ±0.70),(7.00 ±0.52),(2.69 ±1.58) and (4.31 ± 1.28)mm2 in BMS group.VA and SA were similar among groups ( all P ＞0.05 ).LA in LBL group was smaller than SES group ( P ＜ 0.01 ) and significantly larger than in BMS group ( P ＜0.05 ).NA in LBL group was larger than SES group (P ＜0.01 ) and significantly smaller than in BMS group (P ＜ 0.05 ).RI in LBL,SES and BMS groups was 0.95 ± 0.07,1.02 ± 0.04 and 0.98 ± 0.04 ( P ＞0.05).Conclusions There is no late stent malapposition or abnormal remodeling post LBL,SES and BMS implantation up to 1 month in this porcine model.LA in LBL group is smaller than SES group and larger than BMS group at 1 month after implantation in this porcine model.

This study was purposed to investigate the vWF gene A1381T polymorphism in patients with coronary heart disease (CHD). A case-control study was designed, including 104 continuously hospitalized patients with CHD, aging from 40 to 75 years (average 59) and 96 persons underwent physical examination in outpatient department as controls, aging from 39 to 70 years (average 56). The plasma vWF: Ag level of CHD patients and control persons was detected by ILISA. vWF gene A1381T polymorphism was analyzed by the polymerase chain reaction-restriction fragment length polymorphism and sequencing when it is necessary. The data were grouped by gender, blood group and/or genotype in CHD group and control groups. The difference of plasma vWF level between male and female was analyzed by independent sample t test; one way ANOVA was used to analyze the difference of vWF level between different blood group genotypes, while the factorial design ANOVA was used to test the difference of vWF level in plasma between A1381T genotype and/or ABO blood groups. χ(2) Crosstabs were used to test the CHD susceptibility. The results showed that the frequencies of GG genotype (wild type) of vWF gene A1381T polymorphism were 62.5% in CHD group and 67.7% in control group, and the frequencies of AG genotype (heterozygous variant) were 37.5% in CHD group and 32.3% in control group. χ(2) Crosstabs showed no significant correlation between vWF gene A1381T polymorphism (AG) and CHD (OR = 1.258, 95% CI = 0.702 - 2.255, χ(2) = 0.595, p = 0.440). The plasma vWF level in CHD group was statistically very higher than that in control group (p < 0.001), even though the relationship of vWF A1381T polymorphism (rs216311) and susceptibility of CHD in CHD group was not found. The plasma vWF level of AG or GG genotype was higher in CHD group than in control group (p < 0.001). The plasma vWF level of AG genotype was higher than that of GG in CHD group (p < 0.05), but not in control group. The plasma vWF of O blood group was lower than that of A, B and AB blood groups (p < 0.05), while among A, B, AB blood groups, the vWF level was not different (p > 0.05). Among O, A, B, AB blood groups in CHD group, vWF level was not different (p > 0.05). Although the two-way analysis of variance ANOVA showed no interaction of A1381T genotype and ABO blood groups on plasma vWF level, the plasma vWF level in AG mutant of vWF A1381T gene polymorphism with O blood group was higher than that of GG mutant (p = 0.023) in CHD group, not different in other blood groups. It is concluded that there is no association between vWF gene A1381T polymorphism and CHD susceptibility. The plasma vWF level in CHD group interrelated with ABO blood group and A1381T polymorphism, in which the plasma vWF level in AG genotype increase mostly. Plasma vWF level in vWF gene A1381T polymorphism with AG mutant was significantly much higher than GG mutant in CHD. This change may be beneficial to further study the effect of A1381T polymorphism on vWF gene expression and activity.

BACKGROUNDSubclinical apoplexy of pituitary functional adenoma can cause spontaneous remission of hormone hypersecretion. The typical presence of pituitary growth hormone (GH) adenoma is gigantism and/or acromegaly. We investigated the clinical characteristics of patients with spontaneous partial remission of acromegaly or gigantism due to subclinical apoplexy of GH adenoma.

METHODSSix patients with spontaneous remission of acromegaly or gigantism were enrolled. The clinical characteristics, endocrinological evaluation and imageological characteristics were retrospectively analyzed.

RESULTSIn these cases, the initial clinical presences were diabetes mellitus or hypogonadism. No abrupt headache, vomiting, visual function impairment, or conscious disturbance had ever been complained of. The base levels of GH and insulin growth factor-1 (IGF-1) were normal or higher, but nadir GH levels were all still > 1 µg/L in 75 g oral glucose tolerance test. Magnetic resonance imaging detected enlarged sella, partial empty sella and compressed pituitary. The transsphenoidal surgery was performed in 2 cases, and the other patients were conservatively managed. All the patients were in clinical remission.

CONCLUSIONSWhen the clinical presences, endocrine evaluation, biochemical examination and imageology indicate spontaneous remission of GH hypersecretion in patients with gigantism or acromegaly, the diagnosis of subclinical apoplexy of pituitary GH adenoma should be presumed. To these patients, conservative therapy may be appropriate.

OBJECTIVETo assess the significance of stroke volume variation (SVV) and intrathoracic blood volume index (ITBI) on the responsiveness to volume loading in mechanically ventilated canine with hemorrhagic shock.

METHODSHemorrhagic shock canine model was established with the modified Wiggers' method. The heart rate (HR), mean artery pressure (MAP), central venous pressure (CVP), pulmonary artery wedge pressure (PAWP), intrathoracic blood volume index (ITBI) and stroke volume variation (SVV) were investigated by Swan-Ganz catheter or PiCCO monitor. Graded volume loading (VL) was performed. Successive responsive VLs were performed (increase in SV > 5% after VL) until continuous change in SV < 5% (unresponsive) was reached.

RESULTSFourteen canines were studied and a total of 134 VLs were performed. In 94 VLs, an increase in SV of more than 5% was reached. In the other 40 VLs, increase in SV was less than 5%. The change of HR, MAP, ITBI, SVV in responsive were more than those of unresponsive after VL. The change of CVP, PAWP in responsive were less than those of unresponsive. Significant correlation was found between DeltaSV after VL and the baseline values of ITBI, SVV. No correlation was found between DeltaSV and HR, MAP, CVP, PAWP. Significant correlations were also found between DeltaSV and DeltaCVP, DeltaPAWP, DeltaITBI, DeltaSVV after fluid loading. No correlation was found between DeltaSV and DeltaHR, DeltaMAP. By using receiver operating characteristic analysis, the area under the curve were 0.872 for SVV and 0.689 for ITBI, more than those of HR, MAP, CVP, PAWP statistically. As SVV value of 9.5% or more will predict an increase in the SV of at least 5% in response to a VL with a sensitivity of 92.6% and a specificity of 82.5%.

CONCLUSIONSSVV and ITBI were more useful indicators than CVP and PAWP on the assessment of responsiveness to volume loading. SVV as a functional preload parameter and for on-line monitoring may help to improve the hemodynamic management.
