1.White Matter Dementia
Chinese Journal of Clinical Psychology 2001;0(03):-
The concept of white matter dementia was first introduced by Filley in 1988.It was found following behavioral neurologica researches that patients with this type of dementia manifested the dysfunctions of sustained attention,memory retrievial,frontal lobe and visualspatial function.They also had psychiatric manifestations but language and extrapyramidal function remained normal.10 diseases of white matter disorders are listed for understanding the clinical characteristics of this type of dementia.
2.PET-CT in the diagnosis of lung cancer with bone metastasis
Journal of International Oncology 2012;39(8):598-600
Positron emission tomography (PET)/CT plays an important role in the diagnosis of bone metastasis from lung cancer,and can reflect the pathophysiological and morphological changes in lesion of bone metastasis.The sensitivity,specificity and the overall accuracy of PET-CT for the diagnosis of bone metastasis in patients with lung cancer are higher than those of routine methods such as X-ray,CT scan,MRI and SPECT/CT.
3.Study on the correlation between EGFR-STAT3 signal pathwayand laryngeal papilloma
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2009;(18):832-836
Objective:To explore the relationship between the expression of EGFR and STAT3 in human la-ryngeal papilloma and its biological behavior. Method: Reverse transcription polymerasechain reaction(RT-PCR), immunohistochemical staining and Western blot were used to evaluate the mRNA and protein expression of EGFR and STAT3(p-STAT3) in 42 laryngeal papilloma tissues and 15 samples of normal laryngeal tissue, and the rela-tionship between the protein expression of them and clinicpathological parameters was also analysized. Result: The mRNA expression levels of EGFR and STAT3 in laryngeal papilloma tissue were significantly higher than that in normal laryngeal tissue(P<0.05,P<0.01). Protein positive expression of EGFR and p-STAT3 were also detected in a significantly greater proportion of laryngeal papilloma than normal laryngeal tissue by immunohistochemistry and western blot(P<0.01,P<0.05). There was relationship between EGFR and p-STAT3 overexpression in la-ryngeal papilloma(P<0.05). The expression p-STAT3 was correlated with the recurrence and canceration of la-ryngeal papilloma(P<0.05). Conclusion: The EGFR-STAT3 signal transduction pathway may be involved in the pathogenesis of laryngeal papilloma,, and the persistent activation of STAT3 gene plays an important role in the recurrence and canceration of laryngeal papilloma.

Chinese Journal of Primary Medicine and Pharmacy 2013;20(21):3278-3280
Objective To study the effect of letrozole plus metformin on infertility of polycystic ovary syndrome(PCOS).Methods According to the digital table,90 patients with infertility of PCOS were randomly divided into the control group(n =45 cases) and the treatment group(n =45 cases).The patients of the control group were treated though clomiphene,while the patients of the treatment group were treated though letrozole plus metformin.The ovulation rate,pregnancy rate,sex hormones and insulin resistance were detected.Results The homeostasis model assessment of insulin resistance index (HOMA-IR) was (5.72 ± 2.37) before treatment and (3.16 ± 1.39) after treatment in the treatment group.HOMA-IR was (5.69 ± 2.40) before treatment and (4.81 ± 2.06) after treatment in the control group.There was a significantly decrease in the treatment group (t =3.7246,P < 0.05).The ovulation rate was 80% in the treatment group,while 60% in the control group,the difference between the two groups was significant(x2 =4.06,P <0.05).The pregnancy rate was 48.9% in the treatment group,while 28.9% in the control group,the difference between the two groups was significant (x2 =5.77,P < 0.05).Conclusion Letrozole plus metformin could promote the ovulation and decrease insulin resistance.
6.The clinical value of Doppler ultrasound in evaluation of the treatment outcome of alcoholic liver disease
Chinese Journal of Primary Medicine and Pharmacy 2013;20(20):3055-3057
Objective To observe the clinical value of doppler ultrasound in evaluation of the treatment outcome of alcoholic liver disease.Methods 212 patients with alcoholic liver disease were selected.Ultrasound and liver function tests were applied before and after treatment,and temperance and medicines were applied for treating.The effects were used to observe the senlitivity of ultrasound applied in evaluation the treatment outcome of alcoholic liver disease.Results Of 212 cases,95 cases were diagnosed as alcoholic fatty liver disease by ultrasound before treatment,and the detection rate before treatment was 96.70%.51 cases were diagnosed as alcoholic hepatitis and 59 cases were alcoholic cirrhosis.After treatment,there were 37 cases had abnormal ultrasound images in 43 patients with alcoholic liver disease,and the detection rate was 86.04%.And 9 cases were diagnosed as alcoholic fatty liver disease by ultrasound,12 cases were diagnosed as alcoholic hepatitis and 16 cases were alcoholic cirrhosis.Conclusion It was noninvasive,cheap,convenient and repeated by using doppler ultrasound,and it was conducive to grasp the change of the condition of the patients for doctors.Ultrasound could be chosen as the preferred method for diagnosis of alcoholic liver disease.
7.The expression and clinical significance of MMP-2 、MMP-9 and VEGF in tongue squamous cell carcinoma
Chinese Journal of Primary Medicine and Pharmacy 2012;19(3):362-364
Objective To investigate the expression of vascular endothelial growth factor (VEGF)、matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9 (MMP-9) in tongue squamous cell carcinoma and the clinical significance.Methods The expression of MMP-2,MMP-9 and VEGF in 60 cases of tongues quamous cell carcinoma tissues and in 20 cases of normal tongues tissues were examined by immunochemistry.Results The expression of MMP-2,MMP-9 and VEGF was higher in tongues quamous cell carcinoma than that in normal pancreatic parenchyma.In cases with lymph nodes metastasis and TNM stage Ⅲ + Ⅳ,the expression of two markers were significantly higher than those without lymph nodes metastasis and TNM stage Ⅰ + Ⅱ (P < 0.05).A positive correlation was found between the expression of VEGF and MMP-2,MMP-9 in tongues quamous cell carcinoma ( P < 0.05 ).Conclusion The expression of MMP-2,MMP-9 and VEGF was closely correlated with lymph nodes metastasis and TNM stage of tongues quamous cell carcinoma(P < 0.05 ).VEGF and MMP-2,MMP-9 play an important role in the development of tongues quamous cell carcinoma,may cooperate with each other.
