Objective:To assess the clinical value of helium-free magnetocardiography(MCG) in the diagnosis of coronary artery disease(CAD).Methods:A total of 213 patients with suspected CAD undergoing MCG in Beijing Anzhen Hospital were enrolled in the study. All patients underwent coronary CT angiography/invasive coronary angiography(CCTA/ICA) within 48 hours after MCG scanning. The parameters of MCG, including magnetic field multipolarization, magnetic field unipolarization, T-wave flattened, change in magnetic field distribution at TT segment, abnormal T-peak amplitude ration of maximum to minimum, significant movement of poles, magnetic field angle deviation and abnormal distribution of positive pole were used for the evaluation of the stenosis of coronary arteries.Results:Among 213 patients, MCG scanning was completed in 193 cases(90.6%), while 20 cases were excluded for various reasons. The CCTA/ICA results were taken as gold standard, the total coincidence rate of MCG with the degree of stenosis was 88.60%(95% CI: 83.25%-92.72%), the sensitivity and specificity of MCG in the diagnosis of CAD was 89.63%(95% CI: 83.21%-94.21%) and 88.23%(95% CI:78.12%-94.78%), respectively; the positive and negative predictive value were 93.80%(95% CI:88.72%-96.68%) and 81.08%(95% CI:72.15%-87.64%), respectively. Conclusion:MCG is highly accurate in the diagnosis of CAD, it may be widely used clinically as an non-invasive method free of radiation or contrast agent.

Neuropathic pain is a clinical symptom with complex mechanisms and high incidence. The commonly used analgesics have limited efficacy and can cause serious side effects. The theory of chronic pain entering collaterals was proposed by YE Tianshi, a famous physician focusing on warm diseases in the Qing dynasty, on the basis of the ancient therapies for pain. This theory is particularly suitable for the diagnosis and treatment of neuropathic pain in view of the clinical course and manifestations. The chronic neuropathic pain can enter the Yin collateral in deeper sites. The pathogenesis of neuropathic pain is summarized as a deficiency in origin and excess in superficiality. The root cause is the dysfunction of Zang-Fu organs, mainly the liver, kidney and heart, while the superficial causes are phlegm and stasis caused by the obstructed Qi and blood movement due to the consumption of Qi and blood in collaterals. Accordingly, the therapies such as dispelling blood stasis, resolving phlegm, and dredging collaterals should be adopted. This paper expounds the traditional Chinese medicine (TCM) pathogenesis and treatment of neuropathic pain, enriching the knowledge and providing new ideas for the TCM prevention and treatment of this disease as a collateral disease.

Objective: To explore the value of nanoparticles (CN) in lateral cervical lymph node mapping in papillary thyroid carcinoma using carbon. Methods: Thyroid cancer patients with suspicious lymph node metastasis but without typical signs of metastatic disease from March 2016 to November 2017 in Fudan University Shanghai Cancer Center were prospectively included in the cohort. Neck dissection was performed in all patients (compartmentsⅡ-Ⅴ). Suspicious lateral lymph node metastasis was identified using pre-operative ultrasound or computed tomography. CN were used for lymph node mapping during surgery. Results: A total of 70 surgeries were performed in 67 patients, among which 57 were found to have lateral lymph node metastasis (81.4%). The median number of CN-dyed lateral lymph nodes was 6. Compartment IV had the highest number of CN-dyed positive lymph nodes as well as the highest rate of metastasis, followed by compartmentⅢ. In compartmentsⅢandⅣ, the incidence of lymph node metastasis was significantly higher in the CN-dyed group than in the CN-undyed group (P<0.001). When the final pathology of neck dissection was set as the gold standard, lateral CN-dyed lymph node biopsy was found to have a sensitivity of 86.0%; its negative predictive value was 61.9% and its overall accuracy was 88.6%. Conclusions:Injection of CN during surgery was a potential method of mapping lateral lymph nodes in papillary thyroid carcinoma. CompartmentⅢ-ⅣCN-dyed lymph node biopsy had a satisfactory sensitivity and thus, served as a reasonable range for lymph node biopsy.

Stanniocalcin (STC) was ifrst found as a calcium- and phosphate-regulating hormone produced in bony ifsh by the corpuscles of Stannius. In mammals, the homolog STC-1 displays a relative high amino acid sequence identity (nearly 50%) with ifsh STC, and STC-2 has a lower identity (nearly 35%) with STC-1 and ifsh STC. Both STC-1 and STC-2 are expressed in a variety of tissues. The functions of STC have not been understood. But some ifndings have been reported on their cellular localization, gene structure, and expression in different physiological and pathological conditions, which will be clues in elucidating the functions of STC in mammals. Moreover, STC-1 and STC-2 are expressed in many tumor cell lines, suggesting other biological functions of STC in mammals other than mineral metabolism.

Background and purpose:About 80%patients with oral and maxillofacial malignant tumor are oral squamous cell carcinoma (OSCC). OSCC is one of the most common cancers in the world with less than 50%survival rate over 5 years. This experiment aimed to explore the effect of stanniocalcin 2 (STC2) on apoptosis, proliferation, migration and invasion of OSCC cell. Methods:RNA interference (RNAi) vector pLKO.1-shSTC2 was constructed and transfected into KB cells. Cell proliferation and cell apoptosis were then assessed by CCK8, APC Annexin V/7-AAD and lfow cytometry. Differences of migration and invasion between KB scr and KB STC2i were examined by cell scratch and transwell tests. Finally, this study detected the apoptosis-associated proteins and metastasis-associated proteins by Western blot. Results:STC2 down-regulation plasmid was constructed and transfected into KB cells. CCK8 prolifera-tion assay revealed that the STC2 down-regulation inhibited KB cells proliferation. By treating with cisplatin, this study found that STC2 silence could facilitate cell apoptosis signiifcantly. With the knock down of STC2 gene, the expressions of Bcl-2, Caveolin-1 andβ-catenin were decreased but the expression of bax was obviously increased. Conclusion:These data suggest that STC2 may be involved in the apoptosis, proliferation, migration and invasion of OSCC KB cells. Simultaneously, it can signiifcantly weaken the sensitivity of KB cells to chemotherapeutic drug cisplatin.

Objective To observe the effects of irbesartan and amlodipine on insulin sensitivity in obese hypertensive patients. Methods 157 moderate hypertensive patients were divided into two greups,which received irbesartan or amlodipine for 16 weeks. The changes of blood pressure,heart rate and weight were observed. Insulin re-sistance was computed using the homeostasis model assessment (HOMA-IR). Results There was no difference in antihypertensive efficacy between the two groups(P>0.05). After 16 weeks of treatment ,the insulin resistance index decreased by 8.7±2.4 vs 6.1±2.6 (P<0.01) and body mass index decreased(28.1±3.8) kg/m2 vs (27.2± 3.2 ) kg/m2 (P<0.05 ) and mean heart rate raised by (73.1 ±10.0 ) kg/m2 vs ( 79.1±11.4) kg/m2 ( P < 0.01 ) in irbesartan group while no such changes were found in amlodipine treated group. Conclusions In obese hypertensive patients,irbsartan and amlodipine exert similar antihypertensive effect, but irbesartan may help to improve some obe-sity-related metabolize disorder,so the obese hypertensive patients may benefit more from irbsartan than from amlo-dipine.
