Conclusion　pre-infarction angina possesses the protecting effects on ventricular function of first acute myocardial infarction in old people, and can improve the prognosis of first acute myocardial infarction in old people.

Traditional Chinese medicine considers that the final purpose of acupuncture treatment for disease is to harmonize yin and yang. Acupuncture redresses a balance between yin and yang by transmitting information to acupoints and then to corresponding visceral tissues and organs and the brain through the meridian system or the nervous system. In recent years, scholars at home thoroughly studied heart rate variability (HRV) analysis for acupuncture treatment of diseases and found that the regulating effect of acupuncture on visceral organs was closely related to autonomic nerves and acupuncture could restore a balance between sympathetic and parasympathetic nerves. Many scholars explored the effect of acupuncture on diseases related to autonomic nervous dysfunction by HRV frequency domain or time domain analysis and gained a certain achievements. This article summarizes recent years’ domestic studies on HRV-based analysis of acupuncture for diseases with autonomic nervous dysfunction and reviews the close relationship between autonomic nerves and diseases and the related mechanism of acupuncture action.

Objective To explore the clinical value of color Doppler ultrasonography in the diagnosis of uterine carcinosarcoma (UCS).Methods The clinical data and ultrasonographic manifestations of 63 cases of UCS proved by operation and pathology in Obstetrics and Gynecology Hospital of Fudan University from January 2003 to December 2014 were retrospectively analyzed.The clinical features and characteristics of ultrasound images in UCS were summarized and classified according to their ultrasonographic features.Results It mostly occurred in postmenopausal women (77.8％).The average age of the 63 patients of UCS was (57.7 ± 11.5) years old.The most common symptoms of UCS were postmenopauseal vaginal bleeding (57.1％),menstrual disorders (20.6％),vaginal discharge (11.1％),uterine mass or thickened endometrium (11.1％).Tumor marker CA125 was evaluated in 36 women and found to be elevated in 15 women (41.7％),60％ of which (9/15) was less than 200 U/mL.Six cases (16.7％) of relative higher level of serum CA125 (＞ 200 U/mL) were at advanced stage or with malignant ovarian tumors.The sonographic findings of UCS had three types:Uterine cavity type (71.4％),endometrium type (14.3％),and myometrium type (14.3％).The ultrasonographic characteristics of uterine cavity type and myometrium type were fuzzy boundary,irregular shape,and internal uneven echo.Color doppler flow image showed rich blood signals and low resistance index (0.55 + 0.11) of the surrounding and internal artery of the lesions.The large volume of lesion was the characteristic of myometrium type.Conclusions UCS is a very aggressive and extremely rare tumor with the symptoms of postmenopauseal vaginal bleeding,menstrual disorders,vaginal discharge,et al.There are three types of sonographic findings of UCS:uterine cavity type,endometrium type and myometrium type.To strengthen the understanding of UCS and combined with clinical manifestations,the transvaginal color Doppler ultrasound was helpful to early detection,early diagnosis and making the appropriate treatment.

Objective To determine prevalence of dementia in diabetics and non-diabetics, and in different age and gender groups. Methods A case-control study was conducted among participants aged 50 and over in Jing' an temple community in Shanghai. Subjects in diabetics group were matched to non-diabetics groups for age and sex with 1:1 matching. Personal information and case history were collected through questionnaire. The subjects were screened for dementia using the Mini Mental State Examination (MMSE). Subjects that screened positively (indicated by an MMSE score below 19, 21 and 24 among those with illiteracy, elementary school and above junior middle school education, respectively) were subsequently examined by a series of neuropsychological tests. Based on all available information, a diagnosis of dementia was defined according to the Diagnostic and Statistical Manual of Mental Disorders ( DSM )-Ⅳ criteria Results Prevalence of dementia of 4. 75% (23/484, 95% CI: 3. 03%-7.04%) in diabetics was higher than that of 2. 24% (11/490,95% CI: 1.13% -3.98%) in non-diabetics (X~2 = 4.54, P=0.03).Prevalence of dementia among diabetics in age groups of 60-69, 70-79 and 80 and above was 1.94% (2/103), 4. 43 % (9/203) and 14.12% (12/85, trend X~2 =18.04, P <0.01), and in non-diabetics was 1.43% (2/140), 2. 86% (6/210) and 5.00% (3/60, trend X~2 = 4.58, P=0.03), respectively.Prevalence of dementia among female and male in diabetics was 6.55% (19/299) and 2.06% (4/194) (X~2 = 5.18, P = 0.02), respectively, and in non-diabetics was 3.01% (9/299) and 1.05% (2/191).Conclusions Prevalence of dementia is significantly higher in diabetics than in non-diabetics, higher in women than men, and increases as age rises.

ObjectiveTo evaluate the diagnostic value of “taller-than-wide sign” of thyroid malignancy in transverse and longitudinal plane using ultrasound.Methods708 thyroid lesions including 302 benign nodules and 406 malignant nodules ( 390 papillary carcinomas,12 medullary carcinomas,4 follicular carcinomas) that were diagnosed at surgery were included in this study.The sensitivity and specificity of “taller-than-wide sign” in transverse (A/TC ≥ 1 ) and longitudinal plane (A/TL ≥ 1 ) were evaluated using ultrasound.All thyroid malignant lesions were divided into three groups according to size of the nodules:group A≤1 cm; group B≤2 cm,group C＞2 cm.The sensitivity of each group was also evaluated.ResultsThe constituent ratio of “taller-than-wide sign” between benign and malignant nodules was significantly different (P＜0.001 ).The differences of sensitivity of A/TL ≥ 1 and A/TC ≥ 1 among three groups were also found( P ＜0.001),and the sensitivity of A/Tc≥1 was higher than A/TL≥1.ConclusionsA/TC≥1 found by ultrasound contributes to differentiate the thyroid carcinoma from benign nodules.For a large thyroid lesion,other indicators are needed to diagnose thyroid carcinoma.

Objective:To construct a specific small hairpin RNA (shRNA) expressing vectors against human receptor for advanced glycation end product (RAGE) gene and study its inhibitory effect on the proliferation of androgen-independent prostate cancer cells DU145. Methods:Four RAGE specific oligonucleotides were designed and synthesized. These oligonucleotides were annealed to forill double strand DNA fragments and this fragment was cloned into psi-U6 plasmid. The recombinants were transfected into RAGE-overexpressing sub DU145-2C1 cells. Cellular morphology and transfection efficiency were observed under fluorescence microscope. The inhibitory effect of RAGE shRNA construct on RAGE mRNA and protein expression was examined with semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blotting, respectively. The cellular proliferation was detected with cell counting kit-8 (CCK-8). Scratch test was used to observe the migration of DU145 cells.Results:RAGE shRNA expression plasmids were successfully constructed and transfected into sub DU145-2C1 cells. It can effectively inhibit the expression of RAGE mRNA (P<0.05). The inhibitory effects of shRNA RAGE-1 (R1) was the most stronger. The RAGE mRNA expression was inhibited by 84% and RAGE protein expression was inhibited by 27%. Compared with negative control, the proliferation potential was significantly decreased in shRNA RAGE-transfected cells. The cell migration capability had no significant changes. Conclusion:RAGE shRNA effectively inhibited the expression of RAGE mRNA and protein and suppressed the proliferation of DU145 cells in vitro.
