1.Characterization of malignant thyroid nodules:Pathological analysis of 600 cases
Journal of Medical Postgraduates 2003;0(10):-
Objective: Thyroid nodules are common clinical thyroid disorders.The purpose of this study was to investigate the diagnostic value of the clinical characteristics and various parameters of malignant thyroid nodules and the sensitive indexes for their differentiation so as to improve the diagnosis of malignant thyroid nodules and avoid unnecessary procedures or operations.Methods: We retrospectively studied 600 cases of thyroid nodules treated by surgery from 2001 to 2008,divided them into a benign and a malignant group according to the pathological results,and analyzed by multivariate logistic regression the correlation between the nature of thyroid nodules and various factors.Results: Of the 600 cases of thyroid nodules,519(83.47%) were benign and 81(16.53%) were malignant.Clinical symptoms and signs,ultrasonography and CT were all useful in indicating malignancy,especially ultrasonography,whose specificity and diagnostic accuracy were 93.3% and 84.2%,respectively.Multivariate logistic regression analysis revealed a higher rate of malignancy in younger patients with solid or hard nodules,or accompanied with calcification or painless adenophyma in the neck.Conclusion: Clinical symptoms and signs,ultrosonography and CT are of significant value in the diagnosis of malignant thyroid nodules.

AIM: To recognize the importance of ADR monitoring of drugs available on the market from PPA Event. MET- HODS: With reviewing relevant literatures and scanning relevant network stations. we summarlzed the importance of moni- toring ADR of drugs available on the market and signiticance of creating a perfect evaluation mechanisms and systems of ADR monitoring for those drugs. and analysed several method of ADR monitoring and points for attention Finally. we gave several suggestions about enhancing ADR monitoring .RESULTS& CONCLUSION:ADR events can be effectively pre- vented by perfect evaluation mechanisms and ADR monitoring systems of drugs available on the market.
4.Clinical Application Value of MR Fat-suppression Sequence in Breast Neoplasm
Journal of Practical Radiology 2000;0(12):-
Objective To study the clinical value of fat-suppression(FS)sequence and dynamic contrast-enhanced MRI in judging the nature of breast neoplasm.Methods Sixty patients with breast neoplasm(including malignant lesions in 40 cases and benign lesions in 20 cases)proved by histopathology were reviewed.All patients were undergone FS sequence and 30 cases underwent dynamic contrast-enhanced MRI examinations,time-signal curves were acquired.Results 22 malignant lesions in 20 cases and 46 benign lesions in 40 cases were found by FS.Dynamic contrast-enhanced MRI showed 18 malignant and 20 benign lesions.The malignant lesions had visible contrast-enhancement of administration of Gd-DTPA.Type Ⅲ curve was showed in 16 lesions(malignant in 14 and benign in 2),type Ⅱ in 5(malignant in 3 and benign in 2)and type Ⅰ in 17(malignant in 1 and benign in 16).There was significant difference between benign and malignant tumors on the type of time-signal curve(P

7.The roles of lipoprotein-associated phospholipase A2 in carotid artery atherosclerosis and ischemic stroke
International Journal of Cerebrovascular Diseases 2010;18(4):282-285
The lipoprotein-associated phospholipase A2 (Lp-PLA2), a subtype of the phospholipase A2 superfamily, is produced primarily by macrophages and lymphocytes. Lp-PLA2specifically hydrolyzes oxidized phospholipids on oxidized low-density lipoprotein particles,resulting in production of lysophosphatidylcholine and oxidized fatty acids. Lp-PLA2 is expressed in atherosclerotic plaques and in macrophages within a fibrous cap of unstable plaque.Studies haw shown that the plasma Lp-PLA2 activity increases significantly in patients with ischemic stroke, and Lp-PLA2 may become an independent risk factor for predicting ischemic cerebrovascular events. The selective Lp-PLA2 inhibitor can reduce the inflammatory response,enhance the stability of plaques, and inhibit the formation of atherosclerotic plaques, and may become a new class of drugs for preventing the formation of atherosclerotic plaques.
8.Advances in basic and clinical research of ACL reconstruction with autologous hamstring tendon
Chinese Journal of Orthopaedic Trauma 2002;0(04):-
Injury to anterior cruciate ligament (ACL) is the most common lesions of the knee joint. Reconstruction of ACL has been the primary treatment for the instability of the knee. Compared with the traditional reconstruction with patellar tendon, the hamstring tendon has many advantages, such as less damage to the donor site and less incidence of antero-patellar or kneeling pain. This paper highlights the basic and clinical research on ACL reconstruction.
9.Mandible plasma cell myeloma:A case report
Journal of Practical Stomatology 2014;(4):578-579
A case of mandible plasma cell myeloma is reported.Plasma cell myeloma is a monoclonal neoplastic proliferation of plasma cells of bone-marrow derivation,usually multi-centric but jaw bones are rarely involved.The treatment requires precise pathological diagno-sis.The prognosis of solitary jaw bone lesions can be good after treatment.
10.Correlation between NADPH oxidase p22phox CYBA-A930G polymorphism and hypertensive cerebral hemorrhage in Chinese Han population in Shanghai area
International Journal of Cerebrovascular Diseases 2014;22(10):751-755
Objective To investigate the correlation between the NADPH oxidase p22phox-A930G polymorphism and hypertensive intracerebral hemorrhage in Chinese Han population in Shanghai area.Methods The patients with hypertensive intracerebral hemorrhage and normal controls were enrolled.The polymerase chain reaction and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to detect the genotypes and alleles of NADPH oxidase p22phox-A930G.Results A total of 128 patients with hypertensive intracerebral hemorrhage and 151 healthy controls were enrolled.The levels of systolic blood pressure,diastolic blood pressure,glucose,and triacylglycerol,as well as the proportions of smoking and alcohol consumption in patients of the hypertensive intracerebral hemorrhage group were significantly higher than those of the control group (all P< 0.05).There were significant differences in AA,AG,and GG genotypes (42.2%,44.5%,and 13.3% vs.63.6%,27.8%,and 8.6%,x2 =12.757,P =0.002) and in A and G allele (64.5% and 35.5% vs.77.5% and 22.5% ;x2 =8.734,P=0.001) frequencies between the hypertensive intracerebral hemorrhage group and the control group.Multivariatelogistic regression analysis showed that systolic blood pressure ≥ 140 mm Hg (1 mm Hg =0.133 kPa) (odds ratio [OR] 13.952,95% confidence interval [CI] 7.242-26.879; P < 0.001),apolipoprotein A ≥ 0.99 mmol/L (OR 3.139,95% CI 1.012-9.733; P =0.048),and AG +GG genotype (OR 2.333,95% CI 1.253-4.342; P=0.008) were the independent risk factors for hypertensive intracerebral hemorrhage.Conclusions Among the Chinese Han population in Shanghai area,the NADPH oxidase p22phox-A930G polymorphism is an independent risk factor for hypertensive intracerebral hemorrhage.
