Objective To investigate the level of knowledge,attitude and practice(KAP)of pelvic floor dysfunction(PFD)and its influencing factors in pregnant women and provide reference for further health education for pregnant women. Methods Totally 637 pregnant women were investigated by Knowledge-Attitude-Practice (KAP)scale for PFD. Results The average scores of KAP in pregnant women were(31.68 ± 7.73),(16.41 ± 4.01) and (10.57 ± 3.00) respectively. About 85.6% of the pregnant women had interest in knowledge of PFD. Educational background,willing to understand knowledge of PFD,and gestational age were dominant factors affecting KAP of women with PFD. Conclusions The awareness rate of PFD and compliance rate of pelvic floor muscle function exercise in pregnant women are low. Effective measures should be taken to prevent PFD for pregnant women.

Lipids of Thamnidium elegans,Mortierella ramanninace,Rhizopus arrhizus,Pythium irregulare and Rhodotorulla aurantiaca were extracted by Soxhlet extraction,supercritical-CO 2 fluid extraction,acid-heating extraction and organic solvent extraction,respectively.Four extraction methods were evaluated on sample treatment,minimum sample quantity,requirements of apparatus,ability of treating sample and content of lipid.The components of fatty acids were analysed by gas chromatography.Soxhlet extraction can acquired maximum lipid content,but it took the most time.Supercritical-CO 2 fluid extraction and acid-heating extraction has a same lipid content which was lower than that of Soxhlet extraction.Acid-heating extraction was the most handy,and its ability to treat sample in a hour was the most powerful.Organic solvent extraction was less efficient.Acid-heating extraction was a simple and efficient method of fungi lipid extraction fitting to breed mutant strains that highly producting lipid and polyunsaturated fatty acids.

Scientific data is the source of innovation in knowledge. In order to change the situation that there is few information in plenty of data and to obtain useful knowledge which has high information content, it is necessary to clean data and ensure data's accuracy and without noise off when database is established initially. High-quality data comes from high-quality data source. But incomplete and incorrect and irregular data exist widely in the data source of Chinese materia medica. The phenomenon of synonyms and homonym is quite serious, and there is no unified description for the name and origin of Chinese materia medica among different data sources. So data processing including data analysis and research is very important in the establishment of Chinese materia medica database. In order to get the most accurate and standard data, this paper analyzed the items of Medical Plants in Xiandai Bencao Gangmu, including classification analysis of medical plants: distribution analysis of different classes and analysis of medical part; analysis of synonyms and homonym; analysis of incorrect data and analysis of advantage and disadvantage of data sources.

Objective To observe the protective effects of a mixture for protecting liver and supplementing stomach (保肝益胃合剂) on rat acute liver damage induced by carbon tetrachloride (CCl_4). Methods The model of rat acute liver damage was established by injection of CCl_4 2 ml/kg into the abdominal cavity.The rat models were treated respectively by the mixture for protecting liver and supplementing stomach 30 g?kg~(-1)?d~(-1),the polyene phosphatide acid radical choline capsule [Yi Shanfu (易善复), 180 mg?kg~(-1)?d~(-1)],the glycyrrhizic acid diaminogen capsule [Gan Lixin (甘利欣),30 mg?kg~(-1)?d~(-1)] infused into the stomach.The activities of serum alanine transaminase (ALT) and aspartate transaminase (AST) were detected.In the mean time,the liver pathological changes were observed,the degree of liver cell necrosis was evaluated,and the rat mortality was noted in various groups of treatment.Results The values of ALT,AST and the score of liver cell necrosis in the group treated with the mixture for protecting liver and supplementing stomach [(1.168?1.066) kU/L,(1.845?2.212) kU/L,(0.56?0.53) score] were significantly lower than those in the model group [(4.982?3.502) kU/L,(7.030?3.616) kU/L, (1.38?0.92) scores],and all the differences being statistically significant (all P

OBJECTIVETo study the value of multi-slice spiral computed tomography (CT) in the preoperative evaluation of lymph node metastasis.

METHODSTotally 45 patients with gastric cancer detected by 64-slice spiral CT were enrolled in this study. The potential lymph node metastasis was evaluated by measuring or calculating the long diameter, extent of enhancement, and short-to-long diameter ratio of the lymph nodes. The results were compared with postoperative pathological findings.

RESULTA long diameter ≥ 8mm,enhanced density ≥ 80Hu, and short-to-long diameter ratio ≥ 0.7 had the best consistency with postoperative pathological findings.

CONCLUSIONAs a simple and noninvasive technique, multi-slice spiral CT is helpful to identify potential lymph node metastasis of gastric cancer based on long diameter, extent of enhancement, and short-to-long diameter ratio of the lymph nodes, and thus provide important information for surgery selection, prognosis, and development of new procedures.

OBJECTIVETo study the relationship between spiral CT findings and histological differentiation and expressions of p53 and Ki67 in gastric carcinoma.

METHODSTriphasic spiral CT was performed in 158 patients. CT findings included maximal diameter and thickness of tumor in three dimensional CT images, degree of enhancement, mucous situation, lymph nodes, and visceral metastasis were recorded. The expressions of p53 and Ki67 were detected with immunohistochemistry and reverse transcription polymerase chain reaction.

RESULTSThe thickness of tumor (chi2 = 5.554, P = 0.018), degree of enhancement (chi2 = 4.978, P = 0.026), and lymph nodes metastasis (chi2 = 6.061, P = 0.014) in the three dimensional CT images were significantly correlated with tumor histological differentiation. Lymph nodes metastasis was significantly correlated with the expression of p53 (chi2 = 5.028, P = 0.025). The expression of Ki67 was significantly correlated with the thickness of tumor (chi2 = 5.674, P = 0.017) and lymph nodes metastasis (chi2 = 5.028, P = 0.025).

CONCLUSIONMulti-slice CT is a simple and noninvasive technique, and can be used for assessing the histological differentiation of gastric cancer as well as the expressions of p53 and Ki67 before the operation.

This study was to evaluate the role of reticulated platelets (RP) assay in the distinguishing the different causes of thrombocytopenia. The RP and immature platelet fraction (IPF) were stained by a nucleic acid-specific dye oxazine, and assayed by XE-2100 blood cell counter with an upgraded software in the reticulocyte/optical platelet channel. RP and IPF were measured in 137 thrombocytopenic patients and 187 normal controls. The results showed that the mean IPF was 1.07% in normal controls, and 10.28% in 109 patients with immune thrombocytopenia (p<0.01), RP absolute value in ITP group was higher than that in control group, there was significant difference between them (p=0.036). The mean IPF was 10.47% in patients with primary immune thrombocytopenia (PITP), and 9.45% in patients with secondary ITP (SITP). There was no significant difference of IPF between PITP and SITP group (p=0.635), but IPF in these 2 groups both were significantly higher than the normal controls. The mean IPF in 28 thrombocytopenic patients with hypocellular marrow was 2.37%. There was no difference of IPF between thrombocytopenic patients with hypocellular marrow and the normal controls (p=0.252), but the absolute counts of RP in the former was significantly lower than in the latter (p<0.05). The IPF cut-off for a diagnosis of thrombocytopenia with hypercellular marrow was 2.45%, the sensitivity was 92.7% and specificity 94.1%. It is concluded that the whole-blood IPF measurement by XE-2100 blood cell counter is an useful screening test to differentiate patients with thrombocytopenia of different causes. An IPF above 2.45% has both a high sensitivity and specificity for a diagnosis of thrombocytopenia with a hypercellular marrow.

OBJECTIVETo evaluate the clinical efficacy of ultrasound-guided lauromacrogol sclerotherapy for benign thyroid cysts and analyze the factors affecting the efficacy.

METHODSUltrasound-guided lauromacrogol sclerotherapy was performed in 97 patients with a total of 99 benign thyroid cysts. The changes in cystic volume and other thyroid parameters were evaluated at 1, 3, 6, and 12 months after sclerotherapy. According to changes in the cystic volume, the efficacy of sclerotherapy was defined as therapeutic failure (with a volume reduction <50%), treatment success (volume reduction ≥50%) and cure (volume reduction ≥90%). The factors of affecting the efficacy of sclerotherapy was analyzed using COX regression.

RESULTSThe mean cystic volume at 1, 3, 6 and 12 months after sclerotherapy were reduced from the baseline volume of 12.08∓11.56 cmto 5.63∓8.51 cm, 5.96∓8.42 cm, 3.80∓5.50 cmand 2.85∓3.98 cm, respectively, with an average cystic volume reduction rate of (70.02∓33.72)%. Therapeutic success was achieved 82 of the 99 cysts (82.83%) and cure was achieved 63cysts (63.64%) at 12 months after the procedure. A second sclerotherapy was performed for 13 cysts which did not show a volume reduction at 1-3 months after the initial procedure. A disease course of over 12 months was an independent risk factor for a second sclerotherapy (23.7% [9/38] vs 6.6% [4/61], OR=4.473 [1.238-16.169], P=0.022). The efficacy of sclerotherapy was related to cystic cavity separation, cystic fluid viscosity, cystic/solid ratio and cystic wall thickness. COX regression analysis revealed that cystic cavity separation (HR=2.25, 95%CI: 1.19-4.25) and cystic fluid viscosity (HR=2.02, 95%CI: 1.19-3.43) were the major factors affecting the treatment efficacy.

CONCLUSIONUltrasound-guided lauromacrogol sclerotherapy is effective and safe for treatment of benign thyroid cysts, and the maximal treatment effect can be achieved at 6 months after sclerotherapy and in cases of uncomplicated cysts with non-viscous cystic fluid, no solid cystic cavity separation and a disease course of less than 12 months.
