OBJECTIVETo study immunohistochemical expression of cytokeratin19 (CK19), galectin-3 (Gal-3) and HBME-1 in thyroid lesions and to assess their usefulness as markers in the differential diagnoses of thyroid nodular lesions.

METHODSImmunohistochemical staining was performed on formalin-fixed paraffin-embedded tissue of 21 cases of nodular goiters, 14 cases of toxic goiters, 15 cases of follicular adenomas (FA), 13 cases of follicular carcinomas (FC), 13 cases of follicular variant papillary carcinomas (FVPC) and 48 cases of classic papillary carcinomas (CPC).

RESULTSAll three markers were expressed in the cytoplasm with no or weak expression in benign lesions and diffuse and strong in malignant cases. Positive expressions of CK19, Gal-3 and HBME-1 were present in 11of 21, two of 21, four of 21 in nodular goiters, seven of 14, one of 14, one of 14 in toxic goiters, nine of 15, two of 15, two of 15 in FA, 10 of 13, eight of 13, seven of 13 in FC, 13 of 13, 11 of 13, 12 of 13 in FVPC, and 48 of 48, 45 of 48, 46 of 48 in CPC. The expression rates of the three markers between benign lesions (nodular goiters, toxic goiters and FA) and malignant lesions (FA, FVPC and CPC) were statistically significant. Among the three follicular lesions (FA, FC and FVPC), the differences were statistically significant as well. Nine, seven and six cases were negative for all three markers in nodular goiters, toxic goiters and FA, respectively. Only one case in FC was negative for all three markers, no case was all negative in FVPC and CPC; the rate of one case with two or more positive marker expression in nodular goiters, toxic goiters, FA, FC, FVPC and PC was 14.2% (3/21), 21.43% (3/14), 20.0% (3/15), 69.2% (9/13), 92.3% (12/13), 100.0% (48/48), the differences between benign lesions and malignant lesions and between FA, FC and FVPC were also statistically significant.

CONCLUSIONSImmunohistochemical stains of CK19, Gal-3 and HBME-1, especially when used in combination, can be an important adjunct to the histopathological diagnoses of thyroid lesions.

Objective:To explore the mechanism of the active compounds in Banxia Houpo Decoction treating tension type headache through network pharmacology and molecular docking.Methods:The potentially effective components and targets of Banxia Houpo Decoction were screened by TCMSP, and the action targets of tension type headache were obtained by GeneCards, PharmGKB, TTD, Drugbank and OMIM. The intersection target of "Banxia Houpo Decoction - tension type headache" was obtained by Perl software. The protein interaction network was uploaded to STRING database and topological analysis was carried out. With the help of Cytoscape 3.8.0 software, the visualization network of "Banxia Houpo Decoction - medicine ingredient-Target-tension type headache" was constructed, and the GO enrichment analysis and KEGG pathway enrichment analysis of the intersection targets were carried out by using R 4.1.0 language and related programs. The AutoDockTools-1.5.6 software was used to complete the molecular docking analysis.Results:There were 33 intersection targets in Banxia Houpo Decoction and tension type headache. Topological attribute analysis suggested that MAPK1, TP53, ESR1, PTGS2, MYC, CYP1A2, CYP3A4 and GSTP1 might be important potential targets of Banxia Houpo Decoction in the prevention and treatment of tension type headache. GO enrichment analysis showed 516 cell biological processes (BP), 62 cell components (CC) and 149 molecular functions (MF). KEGG pathway enrichment analysis showed that there were 94 related signal pathways, such as cGMP-PKG signaling pathway, Cholinergicsynapse, Serotonergic synapse and TNF signaling pathway.Conclusions:Banxia Houpo Decoction has multi-component, multi-target and multi-pathway characteristics in the prevention and treatment of tension-type headache. It mainly acts on 5-HT synaptic pathway, TNF signal pathway, cholinergic synaptic pathway, G protein coupled receptor pathway and other pathways through ESR1, TP53, PGTS2 and other multi target.

OBJECTIVETo study the protective effect of recombinant adenovirus-mediated human cytosolic glutathione peroxidase (hCGPx) gene transfection on vascular endothelial cells ECV304 from oxidative damage.

METHODSpGEM-T Easy Vector containing hCGPx cDNA and recombinant adenovirus shuttle plasmid pACCMV-pLpA were used to construct the shuttle plasmid pACCMV-hCGPx for cotransfection of 293 cells with pJM17, thereby to obtain the recombinant adenovirus AdCMV-hCGPx. Cultured ECV304 cells were transfected with AdCMV-hCGPx for 24, 48 and 72 h, respectively, with the cells transfected with the empty vector serving as control, and hCGPx gene expression was then examined in the transfected cells. The transfected cell viability and apoptotic cell ratio were evaluated after treatment of the cells with H(2)O(2).

RESULTSThe expression ratio of hCGPx gene was significantly higher in the AdCMV-hCGPx-transfected cells than in those with empty vector transfection (P<0.01). The hCGPx gene-transfected cells showed significantly higher viability and significantly lower apoptotic ratio than the control cells following challenge with H(2)O(2)-induced oxidative damage.

CONCLUSIONhCGPx gene transfer mediated by recombinant adenovirus protects the vascular endothelial cells from oxidative damage in vitro, possibly due to the antioxidative and apoptosis-inhibiting effect of hCGPx.

OBJECTIVETo study the surgical indications, approaches and the clinical results of the total spondylectomy and instrumentation reconstruction in the treatment of cervical spinal tumor.

METHODSFrom October 1998 to October 2003, 39 patients with lower cervical bone tumors, including 34 cases with primary tumor and 5 cases with metastatic tumor, were admitted and operated on with total spondylectomy. The patients underwent anteroposterior total spondylectomy including anterior cervical plating, titanium mesh reconstruction and posterior instrumentation based on the location of tumor lesions in the lower cervical spine. One vertebral level total spondylectomy was performed in 29 cases, two level in 7 cases and three level in 3 cases.

RESULTSThe postoperative follow-up ranged from 6 months to 4 years. A majority of patients achieved good results postoperatively. Nineteen cases had complete relief of neurological status. One patient died of multiple metastases and systemic failure 24 months later. One case with malignant neurilemmoma developed local recurrence one year postoperatively.

CONCLUSIONAnteroposterior total spondylectomy and reconstruction can reduce local recurrence, improve neurological function and increase operation therapeutic effect. Meanwhile, the technique of cervical total spondylectomy carries relatively greater risks and should be more attention to the operation indication.

OBJECTIVETo explore the characteristics of severe acute respiratory syndrome (SARS) transmission in the population base on analyzing the first imported case and the chains of transmission.

METHODSFor the first imported SARS case and cases who were transmitted by the index case, epidemiological investigations were conducted using the guidelines for surveillance and case investigation issued by the Ministry of Health. Data as the date of onset of symptoms, date of hospitalization, contact history etc. for each of the cases and their close contacts were collected and analyzed.

RESULTSThe first imported SARS case introduced to Beijing had infected 9 people within the family and at the hospital, with two of whom died of the same disease. The incubation period for that index case was 4 days, and that for the cases considered to be the secondary and tertiary generations were 7 and 8 days, respectively. The shorter the incubation period, the longer the fever would last and clinically more severe.

CONCLUSIONOne of the epidemiological characteristics of SARS in Beijing was noticed that the disease clustered in families and hospitals. Infection through droplets and close contact has been viewed as the primary mode of transmission.

OBJECTIVETo study immunohistochemical expression of GADD153 and assess its usefulness as markers in the differential diagnoses in follicular tumors of the thyroid.

METHODSImmunohistochemical staining was performed on formalin-fixed paraffin-embedded tissue of 34 cases of follicular thyroid adenomas (FTA), 46 cases of follicular thyroid carcinomas (FTC), 29 cases of follicular variant papillary carcinomas (FVPC).

RESULTS(1) GADD153 was expressed in cell nucleus with positive or strong positive expression in FTC, and no or weak expression in FTA and FVPC. The positive expressions of GADD153 were present in 38 of 46(82.6%) in FTC, 11 of 34(32.4%) in FTA and three of 29(10.3%) in FVPC, the positive expression rate in FTC was obviously higher than that in FTA and in FVPC, the differences were statistically significant (χ² = 20.80 and 37.48; P < 0.01). (2) CK19, Galectin-3 (Gal-3) and HBME-1 were all expressed in the cytoplasm, the positive expressions of CK19, Gal-3 and HBME-1 were present in 54.3% (25/46), 67.4% (31/46) and 58.7% (27/46) in FTC; 50.0% (17/34), 29.4% (10/34) and 32.4% (11/34) in FTA; 100% (29/29), 93.1% (27/29) and 89.7% (26/29) in FVPC, the differences were statistically significant as well (χ² = 21.20 and 8.22; P < 0.01). (3) According to the expressions of CK19, Gal-3, HBME-1 and GADD153, we divided the results into low expression group (0 or 1+) and high expression group (2+ or 3+), the sensitivity and the specificity were calculated. in FTA, the sensitivity were 26.5%, 8.8%, 2.9% and 11.8%; the specificity were 50.7%, 52.0%, 54.7% and 58.7%. in FTC, the sensitivity were 19.6%, 26.1%, 23.9% and 65.2%; the specificity were 41.3%, 57.1%, 62.0% and 92.1%. in FVPC, the sensitivity were 96.6%, 82.8%, 79.3% and 3.4%; the specificity were 77.5%, 81.3%, 85.0% and 57.5%.

CONCLUSIONSThe sensitivity and the specificity of GADD153 expression are well for diagnosing FTC, and CK19, Gal-3, HBME-1 are well for FVPC. The four markers when used in combination, are better to identify the follicular tumors of the thyroid.
