Objective To explore the clinical feature,diagnosis,treatment and prognosis of Hashimoto′s thyroiditis(HT) combined with hyperthyroidism in children.Methods The clinical features of 56 children with HT combined with hyperthyroidism,including clinical features,complications,thyroid hormone,thyroglobulin antibody(TGAb),thyroid peroxidase antibody(TPOAb),the detection of ultrasonic imaging and fine needle aspiration biopsies,diagnosis,treatment and prognosis were analyzed.Results The proportion of men to women was 16 in all 56 children,and the mean age at diagnosis was(9.95?2.09) years.The percentage of positive TGAb and TPOAb were 93% and 98%,respectively in all the 56 children.One child was diagnosed as HT combined with hyperthyroidism coexistent and myasthenia gravis type Ⅰ.The duration of hyperthyroidism ranged from 3 to 24 months.There were 14 children who had hypothyrodism and 8 children were euthyroid in all the 56 children.Conclusions Children with HT hyperthyroidism are more frequent in young females.TGAb and TPOAb are important markers for the diagnosis of HT.Pharmacotherapy is the first choice to treat HT hyperthyroidism.Hyperthyroidism is a clinical process of HT,and the percentage of children with hypothyrodism is increasing along with the development of disease.

We established an ELISPOT for bovine interferon-gamma (BoIFN-γ), and applied it in the diagnosis of bovine tuberculosis (bTB). Monoclonal antibodies that can bind with native BoIFN-γ were screened as the coating antibody and detecting antibody. After optimization of detecting conditions including coating antibody concentration, cell number, and detecting antibody concentration, the ELISPOT assay was established. Peripheral mononuclear cells (PBMCs) isolated from 30 cows were co-cultured with PPD, and detected with the ELISPOT assay. The optimal conditions of ELISPOT assay were 2.5 μg/mL coating antibody 2G5, 2.5 x 10(5) cells/well, and 1 μg/mL detecting antibody Bio-5E11. In these 30 cows tested both with the ELISPOT assay and the BOVIGAM kit, 11 cows were proved to be positive in ELISOPT assay with the sensitivity of 78.6%, and 12 cows were proved to be negative in ELISOPT assay with the specificity of 75%. The ELISPOT assay for BoIFN-γ could be used to detect bTB efficiently and it might be an alternative method for the diagnosis of bTB.

OBJECTIVETo analyse the causes and the management of massive hemorrhage in hepatectomy.

METHODSWith over 1 000 ml of bleeding, 4 368 patients with hepatectomy between 1955 and 2000 were analysed retrospectively.

RESULTSAmong 4 368 patients receiving hepatectomy, 286 (6.5%) had massive hemorrhage because of damage to the major hepatic veins, portal hypertension, hepatic insufficiency, and the extensive adhesion around the tumor. Massive hemorrhage was managed by repair and transfixation of the damaged vessels; transfixation or devascularization of variceal bleeding; complete vessels ligation of the hepatic section with mattress suture; resection of the ruptured tumor after temporary occlusion of the porta hepatis; fibrinogen infusion; hot saline compression of the surface of the wound and/or daub biological glue; argon beam coagulation and packs placement.

CONCLUSIONSLight performance and nonforce dragging of liver can reduce massive hemorrhage caused by major vessel injury or tumor rupture. Normothetic occlusion of porta hepatis can reduce blood loss effectively when liver resection. In situ hepatectomy must be adopted if there is extensive adhesion around the tumor. Packs placement is still an effective measure to stop bleeding caused by defective coagulation and extensive blood oozing of wound surface.

OBJECTIVETo investigate the apoptosis-inducing effect of Ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F), a compound isolated from Pteris semipinnata L (PsL), on human gastric cancer SGC7901 cells and explore its mechanism.

METHODSThe inhibitory effect of 5F on SGC7901 cells was observed by MTT assay and flow cytometry, and the changes of the expression of Bcl-2 and Bax in SGC7901 cells following 5F exposure were evaluated by Western blot analysis.

RESULTS5F inhibited the proliferation of SGC7901 cells in a concentration- and time-dependent manner, and the cell apoptosis induced by 5F was confirmed by Annexin V-EGFP staining and caspase-3 activation assay. The cell apoptosis induced by 5F was associated with decreased Bcl-2 and increased Bax expressions.

CONCLUSION5F exposure induces apoptosis in SGC7901 cells by activating mitochondrial apoptotic pathways.

OBJECTIVETo investigate the effect of small interfering RNA (siRNA) targeting Apollon in enhancing the chemosensitivity of hepatocellular carcinoma (HCC) cells in vitro.

METHODSHCC cells transfected with the siRNA targeting Apollon were tested for Apollon protein expression using Western blotting. MTT assay and ELISA were used to evaluate the proliferation and apoptosis of HCC cells transfected with siRNA after exposure to 5-FU or adriamycin.

RESULTSApollon siRNA obviously down-regulated Apollon protein expression in HCC cells. The siRNA-mediated suppression of Apollon expression resulted in a marked inhibition of cell growth and increased apoptotic rate of HCC cells, and enhanced both the growth-inhibiting and apoptosis-inducing effects of the chemotherapeutic drugs.

CONCLUSIONApollon siRNA can enhance the chemosensitivity of HCC cells to the chemotherapeutic drugs. Apollon can be a potentially important and feasible therapeutic target for HCC.

OBJECTIVETo explore the association of blood and cerebrospinal fluid (CSF) IgG contents and the severity of craniocerebral injury.

METHODSTotalling 143 patients with craniocerebral injury were divided into 3 groups according Glasgow Coma Scale (GCS) scores, namely the mild injury group with GCS score of 12-15 (n=41), moderate injury group with GCS score of 9-11 (n=71) and severe injury group (GCS score 3-8, n=32). Another 9 patients with congenital hydrocephalus were also recruited as the control group. The CSF and blood samples were collected from these patients to measure the IgG contents 4 and 14 days and 1, 2, and 6 months after the injury, respectively. Physical disabilities of the patients were estimated with Rappaport's disability rating scale (DRS), whose correlations with CSF and blood IgG contents were analyzed.

RESULTSIn the early stage of moderate to severe brain injury, the IgG content was lowered significantly in the blood but increased in CSF as compared with the control patients (P<0.05), and the changes in CSF and blood IgG displayed a significant correlation with the severity of the injury (r=0.950, P<0.01). During the recovery of severe brain injury, DRS score was in inverse correlation with blood IgG content but in positive correlation with CSF IgG content (Spearman's correlation coefficient of 0.800, P<0.05).

CONCLUSIONIn the early stage of brain injury, detection of blood IgG content may help with the assessment of the injury severity. During the recovery of the injury, dynamic monitoring of blood and CSF IgG contents provides clues of the outcome of the patients and benefit the modification of the treatment plan.

OBJECTIVETo investigate the prevalence of chronic prostatitis in men with premature ejaculation.

METHODSThe segmented urine specimens before and after prostatic massage and the expressed prostatic secretion specimens from 106 patients with premature ejaculation and 38 controls were evaluated by microscopic and/or bacteriological studies. The prevalence of premature ejaculation was also investigated in 120 patients with chronic prostatitis.

RESULTSProstatic inflammation was found in 46.2% and chronic bacterial prostatitis in 34.7% of the subjects with premature ejaculation, respectively. Compared with the controls, the findings were statistically significant (P < 0.05). The prevalence of premature ejaculation in the patients with chronic prostatitis was 47.5% (57/120).

CONCLUSIONSChronic prostatic inflammation may play a role in the pathogenesis of some cases of premature ejaculation and it is important to give a careful examination of the prostate before initiating any therapy for premature ejaculation.

OBJECTIVETo investigate the effect of Salvia miltiorrhiza on glomerulosclerosis induced by Ang II.

METHODRat mesangial cells were exposed to 100 nmol L(-1) Ang II. Meanwhile, we added S. miltiorrhiza injection of different concentrations to Mcs. PAI-1 mRNA and protein, TGF-beta1 in serum free MEM medium, and the level of cellular reactive oxygen species (ROS) were measured.

RESULTS. miltiorrhiza notably attenuated Ang II induced expression of PAI-1 in a concentration-dependent manner. Meanwhile, S. miltiorrhiza suppressed the production of TGF-beta1 and cellular ROS in mesangial cells.

CONCLUSIONS. miltiorrhiza can alleviate glomerular sclerosis. The renoprotective effects of S. miltiorrhiza may be due to its ability to decrease Ang II -induced PAI-1 and TGF-beta1 secretion and cellular ROS level.

OBJECTIVETo investigate the relationship between the protein expression of T-lymphoma invasion and metastasis gene 1 (Tiam-1) and the biological behaviors of nasopharyngeal carcinoma (NPC).

METHODSImmunohistochemistry was performed to detect the expressions of Tiam-1 protein in 60 specimens of NPC tissue, 20 specimens of chronic nasopharyngitis (CN) tissue, and 6 tumor tissues from nude mice inoculated with metastatic human NPC cells.

RESULTSThe positivity rate and average score for Tiam-1 expression were significantly higher in NPC tissues than in CN tissue (63.33% vs 36.67%, 2.9167 +/- 1.3057 vs 0.7000 +/- 0.9234; chi(2)=20.429, P=0.001; t=7.0162, P=0.0000, respectively). No difference was found in Tiam-1 expression among NPC patients in different T stages (F=2.36, P=0.0811), while the expression differed significantly between the patients with lymph node metastasis and those without metastasis, and also between patients with organ metastasis and those without (P=0.0001). High Tiam-1 expressions were found in the tumor tissues in nude mice inoculated with metastatic NPC cells.

CONCLUSIONTiam-1 expression is closely associated with the invasiveness and metastasis of NPC, indicating that Tiam-1 is an important factor that promotes the invasion and metastasis of NPC.
