OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).

METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.

RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.

CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

Objective To explore the feasible of diagnosing ischemic cerebrovascular diseases by detecting central retina artery sclerosis(CRA) with color Doppler ultrasonography.Methods210 patients with ischemic cerebrovascular disease(420 eyes) and 80 healthy volunteers(160 eyes) were examined by color Doppler flow imaging(CDFI) to detect double sides blood frequency spectrum of CRA and hemodynamic parameters of CRA including peak systolic velocity(PSV),end of diastolic velocity(EDV)and resistant index(RI).ResultsThe blood frequency spectrum of CRA showed three apices and two vales or slanting triangle in healthy volunteers.But in patients with ischemic cerebrovascular disease,the blood frequency spectrum changed,and PSV and EDV were slower and RI increased compared with those in the healthy volunteers(PP<0.05～0.001).ConclusionIn patients with ischemic cerebrovascular disease,the blood flow of CRA is slower and RI increases compared with health individuals.The color Doppler ultrasonography can used for diagnosis of CRA sclerosis.

Biphasic dissolution test, consisting of immiscible aqueous and organic phase, is an in vitro dissolution method that simultaneously measures the dissolution and partition of drugs. Due to the advantages of simulating in vivo absorption and overcoming the influence of surfactants on dissolution, it has been widely used to evaluate the poorly soluble drugs in vitro dissolution. Based on the relevant research in this field in recent years, this review summarizes the history, dissolution device, theoretical model and application of the biphasic dissolution test. Finally, the prospects in the development of biphasic dissolution test are also outlined.

Objective:To meet the individualized needs of residents in standardized residency training of cardiac intervention specialty for cardiac ultrasound teaching, to construct a bionic 3D printing model of ultrasound source, and to discuss its application value in ultrasound teaching and simulation exercises.Methods:Sixty residents majored in cardiovascular medicine receiving standardized residency training of ultrasound in ultrasound imaging department of Renmin Hospital of Wuhan University were randomized into experimental group and control group in average. The experimental group adopted ultrasound bionic 3D printing heart model combined with problem-based learning (PBL) teaching method, and the control group adopted traditional multimedia PPT combined with PBL teaching method. At the end of teaching activities, theoretical examination, operation assessment and questionnaire survey were conducted to evaluate and compare the teaching effect between the two groups. SPSS 21.0 software was performed for t test. Results:The theoretical examination scores of the experimental group and the control group were (81.4±8.2) points and (74.8±9.4) points, respectively, P=0.002, and the operation assessment scores were (89.1±5.6) points and (71.5±8.8) points, respectively, P<0.001. The questionnaire survey showed that the experimental group had better feedbacks than the control group in the aspects of mastery of heart anatomy knowledge, learning experience, learning interest, learning efficiency, understanding of interventional heart disease, clinical skills of interventional operation and overall satisfaction (all P<0.05). Conclusions:Ultrasound bionic 3D printing combined with PBL teaching method can help strengthen the mastery of cardiac anatomy knowledge, promote the learning experience of cardiac ultrasound and improve the skills of interventional operation. The teaching effect is significant and the students' satisfaction is high.

The optimal plane for measurement of the right ventricular (RV) volumes by real-time three-dimensional echocardiography (RT3DE) was determined and the feasibility and accuracy of RT3DE in studying RV systolic function was assessed. RV "Full volume" images were acquired by RT3DE in 22 healthy subjects. RV end-diastolic volumes (RVEDV) and end-systolic volumes (RVESV) were outlined using apical biplane, 4-plane, 8-plane, 16-plane offline separately. RVSV and RVEF were calculated. Meanwhile tricuspid annual systolic excursion (TASE) was measured by M-mode echo. LVSV was outlined by 2-D echo according to the biplane Simpson's rule. The results showed: (1) There was a good correlation between RVSV measured from series planes and LVSV from 2-D echo (r = 0.73; r = 0.69; r = 0.63; r = 0.66, P < O. 25-0. 0025); (2) There were significant differences between RVEDV in biplane and those in 4-, 8-, 16-plane (P < 0.001). There was also difference between RV volume in 4-plane and that in 8-plane (P < 0.05), but there was no significant difference between RV volume in 8-plane and that in 16-plane (P > 0.05); (3) Inter-observers and intro-observers variability analysis showed that there were close agreements and relations for RV volumes (r = 0.986, P < 0.001; r = 0.93, P < 0.001); (4) There was a significantly positive correlation of TASE to RVSV and RVEF from RT3DE (r = 0.83; r = 0.90). So RV volume measures with RT3DE are rapid, accurate and reproducible. In view of RV's complex shape, apical 8-plane method is better in clinical use. It may allow early detection of RV systolic function.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.
