OBJECTIVETo explore the Chinese medicine syndrome type distribution in patients with polycystic ovary syndrome (PCOS) and its relationship with sexual hormones.

METHODSChinese medicine syndrome types of 212 PCOS patients were differentiated and sorted by adopting fuzzy mean C clustering method, and their relationship with the indices of sexual hormones detected on the 3rd to 5th day of menstrual cycle was analyzed, with the values got from 20 healthy women for controls.

RESULTSIntermingling syndromes were commonly seen in PCOS patients. Shen-deficiency syndrome (presented in 64 patients) and Gan-qi stagnancy syndrome (61 patients) were the dominance, accounting for 30.2% and 28.8% respectively, significantly higher than that of other syndromes (P < 0.05), which were Pi-deficiency syndrome (41 patients, 19.3%), phlegm-dampness syndrome (33 patients, 15.6%) and blood stasis syndrome (13 patients, 6.1%). Levels of estradiol (E2), testosterone (T), luteinzing hormone (LH), dehydroiso-androsterone (DHEA-S) and prolactin (PRL) were higher, while the level of sexual hormone binding protein (SHBG) was lower in PCOS patients than those in control, follicular stimulating hormone (FSH) level in patients of Shen-deficiency syndrome and phlegm-dampness syndrome was high than that in control (P < 0.05 and P < 0.01). However, no significant differences were found in comparing the various sexual endocrinal indices between patients with different syndrome types (P > 0.05). Besides, the level of PRL was positively correlated with LH and E2 levels in patients.

CONCLUSIONChinese medicine syndromes presented in patients with PCOS are mostly intermingling, Shen-deficiency and Gan-stagnancy are the basic syndromes, and there is some correlation between syndrome type and sexual hormone levels.

Objective To analyze the factors related to the occurrence of complications in performing CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle. Methods CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle was carried out in a total of 58 patients. The postoperative complications were recorded, and the related factors causing complication were analyzed. Results Successful puncturing was achieved in all patients with a technical success rate of 100%. Postoperative complications included pulmonary hemorrhage (n=11,19.0%), a little amount of bleeding in needle tract (n=7,12.1%), hemoptysis (n=3,5.2%), hemothorax (n=1,1.7%), and pneumothorax (n=10,17.2%). Chi-square test showed that the occurrence of pulmonary hemorrhage bore a close relationship to the lesion’s diameter, the distance between the lesion and the chest wall, the lesion’s location and times of puncturing (P<0.05). The occurrence of pneumothorax was closely correlated with the age, the distance between the lesion and the chest wall, the presence of perifocal emphysema, the lesion’s location and times of puncturing (P<0.05). Univariate analysis indicated that the postoperative complications were liable to occur in the patients whose imaging examination showed perifocal emphysema and lung hilar lesion, and who had more than two independent risk factors (P<0.05). Conclusion CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle is an accurate and safe technique with relatively higher positive diagnosis rate, but this technique should be carefully used in patients who has perifocal emphysema, or lung hilar lesion, or more than two independent risk factors.(J Intervent Radiol, 2015, 24:792-796)

Objective To explore the inhibitory effect of Oldenlandia diffusa extract on colorectal cancer angiogenesis in BALB/c mice. Methods Thirty-two BALB/c mice with subcutaneous CT26 colon cancer animal model were randomly equally divided into four groups,including the control group (groupⅠ,saline 0.1 mL/(10. d), O. diffusa ethanol extract of 90 mg/(kg.d) (groupⅡ), O. diffusa ethanol extract of 180 mg/(kg.d) (groupⅢ) and O. diffusa ethanol extract of 360 mg/(kg.d) (group Ⅳ) . Each group of mice were treated with intragastric administration of law administration 12 days after vaccination, then stopped and continue fed to 32 days, and the mice were killed. Micro-vascular dense ( MVD) was observed and countered under the microscopy by immunohistory chemistry. Results The murine colon tumor volumes of GroupⅡ,ⅢandⅣwere significantly less than that of groupⅠ,with significant difference ( <0.05) . The tumor microvessel density values of four groups was (7.83±2.87), (5.32±1.27), (1.77±0.70) and (1.87±0.68),respectively. The number of tumor blood vessels in GroupⅡ,Ⅲ and Ⅳ were significantly less than that of Ⅰ group, with significant difference ( <0.05) . Conclusion Within a certain dose range, the ethanol extract of O. diffusa can significantly inhibit the mouse colon cancer and the mechanism may be realated to inhibiting tumor angiogenesis.

Objective To investigate the effect of polymorphism of TNF-?gene G308A on sever- ity of myocardial damage during cardiopulmonary bypass(CPB).Methods Sixty-three congenital ca- ses with ventrieualr septal defect(VSD)were divided into groups TNF1 and TNF2 after TNF-?gene pol- ymorphism was identified by polymerase chain reaction-restriction fragment length polymorphism(PCR- RFLP)before surgery.When the right atrium was opened and closed,specimens of myocardium were ob- tained to study the ultrastructural changes by electron microscope and determine expression of TNF-?mR- NA.Concentration of TNF-?in plasma was measured by radio-immunity after anesthetic induction(T1), 20 minutes of CPB(T2),at the end of CPB(T3) and six hours after CPB(T4)in all cases,respective- ly.Results (1)TNF-?level and the expression of TNF-?mRNA in myocardium were significantly increased during CPB(P＜0.05)in both groups.(2)TNF-?mRNA level of group TNF2 was significant- ly higher than that of group TNF1(P＜0.05).The myocardial CK-MB in group TNF2 was significantly higher than that in group TNF1 at 24 hours postoperatively(P＜0.01).The electron microscope showed more severe ultrastructural changes of myocardium in TNF2 group compared with that in group TNF1(P＜0.05).(3)The concentration of TNF-?in blood plasma in group TNF2 was significantly higher than that in group TNF1 at time points of T2-T4(P＜0.05).Conclusion Polymorphism of TNF-?gene G308A may influence the transcription and production of TNF-?in vivo and hence affect severity of myo- cardial damage.
