Methods Thirty-six cases of infertility underwent HyCoSy using SonoVue and compared with laparoscopie hydrotubation. Resnlts Among 69 fallopian tubes,22 of them were diagnosed to be obstructive by HyCoSy. Compared with laparoscopic hydrotubation, the sensitivity and specificity of HyCoSy were 90. 5 % and 93.8 %, respectively. Conclusions HyCoSy is a convenient, non-invasive, non-radiative method,which may be regarded as an effective tool to assess the fallopian tubes in patients with infertility.

Objective To understand the current status of infections of intestinal parasites of population in Taixing City,Ji-angsu Province. Methods The infection rates and densities of human intestinal parasites were investigated according to the methods of the National Investigation Scheme on Human Principal Parasites,and the data of society,economy and disease con-trol were collected and analyzed. Results Among 2 556 people investigated in five villages,16 persons were found with intesti-nal parasites, with an infection rate of 0.63%. The infection rate was higher in residents with a low education level than in others and it was higher in the age group over 50 years than in the group under 50 years. The infection density was mild and the most was the single parasite infection. Conclusions The current status of intestinal parasite infections of population in Taixing City has reached the county-level control standard of Jiangsu Province. Therefore,the preventive strategy and measures should be ad-justed and the monitoring work should be strengthened.

Objective:To elucidate the changes in apparent diffusion coefficients(ADC)by quantify diffusion weighted (DW)magnetic resonance imaging(MRI)in patients with Alzbeimer's disease(AD),and the relationship between micro-structure changes of white matter(WM)and the cognitive impairment thereof.Methods:The DW-MRI was performed in 30 probable AD patients and 30 normal controls with normal-appearing white matter(NAWM).The ADC was measured in different WM areas.The neurologic and neuropsychological assessments were examined with mini-mental state examination(MMSE)in patients.The ADC were determined in standard regions of the frontal,temporal,occipital and parietal white matter,genu,splenium of the corpus callosum.Results:The value of ADC was higher in frontal,splenium corpus callosum,temporal,and parietal white matter of AD group than that of control(P ＜ 0.01).There was no significant difference in the ADC value of genu and occipital white matter between AD and control groups(P＞ 0.05).The score of MMSE was 24.1±0.8 in AD group.The ADC values of parietal,splenium of the corpus callosum and frontal white matter were significantly negatively correlated with MMSE scores in AD group(P ＜ 0.05 or P ＜ 0.01).There was no correlation between the ADC values of genu of the corpus eallosum,temporal and occipital white matter with the MMSE score(P ＞ 0.05).Conclusion:The quantitative DWI analysis of MRI DWI may be helpful in assessing WM abnormalities in AD.The parietal WM abnormalities may play an important role in the development of dementia.It was showed that Alzheimer's cognitive decline with ADC value and micro-structure of white matter was closely related.

Objective To investigate the effect of PKG on the secretion of IL-6, IL-10, and TNF-αin THP-1 macrophage-derived foam cells. Methods THP-1 monocytes were induced to construct macrophages by treating with 160 nmol/L TPA. Then the macrophages were further treated with 50 mg/L ox-LDL to become foam cells. Four groups were set in this study, including the macrophage group, the foam cell group, the group of foam cell treated with PKG agonist 8-Br-cGMP, and the group of foam cell treated with PKG inhibitor KT-5823. The morphology of THP-1 cells, macrophages and foam cells were observed under microscope. The cellular lipid accumulation was detected by oil red ostaining. The secretion of IL-6, IL-10, and TNF-α into the supernatant was detected by ELISA assay. Results The foam cell was obtained after macrophage incubated with ox-LDL for 48 hours. The secretion of IL-6 and TNF-α increased significantly from the foam cells than that from the macrophages (P<0.05). After the THP-1 monocyte-derived macrophages were incubated with 8-Br-cGMP, the secretion of IL-6 in the supernatant decreased significantly ( P < 0 . 05 ) and IL-10 level in the supernatant increased significantly (P < 0.05). After the macrophages were incubated with KT-5823, the secretion of IL-10 decreased significantly (P<0.05), but the secretion of IL-6 was not significantly changed (P>0.05). After incubation with 8-Br-cGMP, the secretion of IL-6 and TNF-α from the macrophage-derived foam cells decreased significantly (P < 0.05), but IL-10 increased significantly (P<0.05). After the foam cells were treated with KT-5823, the secretion of IL-6 and TNF-αwere also decreased significantly (P<0.05), with no significant change of IL-10 secretion (P > 0.05). Conclusions PKG may enhance the expression of anti-inflammatory cytokine IL-10, and inhibit the expression of inflammatory cytokine IL-6 and TNF-α, contributing to prevent the development of inflammation. PKG might have a potential anti-atherosclerosis effect.

Objective To investigate the clinical value of hysterosalpingo-contrast-sonography (HyCoSy) with high-pressure syringe injection and time-intensity curve analysis in the diagnosis of women infertility due to tube obstruction.Methods Fifty-six women with infertility underwent HyCoSy with compressive injection of SonoVue with a balloon catheter and high-pressure syringe.Time-intensity curve based on Autotracking Contrast Quatification (ACQ) software was analyzed in all patients.The arrival time (AT) of microbubbles from uterine cavity to tube fimbria was analyzed between partially obstructed tube group and control group.Results The AT in the group of partially obstructed tubes was (3.49 ± 1.70) s,while the AT in the group of freely patent tubes was (1.14-± 0.37)s,there was statistical difference of AT between the group of partially obstructed tubes and the group of freely patent tubes (P =0.000).According to ROC results,the optimization point of AT was 1.65 s,the sensitivity,specificity,positive predictive value and negative predictive value were 92.6％,93.3％,96.2％ and 87.5％,respectively.Conclusions High-pressure syringe injection in HyCoSy is useful for regular administration and high image quality.The AT could be considered as the diagnostic indices in the evaluation of fallopian tube patency for infertile women.
