Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

Objective To investigate the clinical effect of treatment with local skin flap after primary surgical resection of non melanoma skin cancer.Methods A total of 176 patients with head and facial skin cancer who were admitted into our hospital from September 2008 to September 2015 were divided into three groups according to different repair plans.Namely,the suture group (41 cases),the local skin flap group (81 cases) and the skin graft group (54 cases).The repair effect of the three groups were compared after the operation.Results The good rate was 68.39%(28/41) in the suture group,98.77%(80/81) in the local skin flap group,and 83.33%(45/54) in the skin graft group,and it was significantly higher than any of the other two groups with statistically significant difference(P<0.05).The satisfaction rate of the local skin flap group was significantly better than that of the suture group,and the difference was statistically significant(P<0.05).But there was no significant difference in the satisfaction rate when compared with the skin graft group(P>0.05).The 3 groups were followed up for a period of 1 year,as a result,there was no recurrence and distant metastasis.Conclusion For patients with head and facial non melanoma skin cancer,repaired with local skin flap healing treatment after primary surgical resection can not only get high healing rate but also significant improvement of patient satisfaction rate.In addition,it can lower the rate of recurrence and distant metastasis after operation.

Objective To discuss the clinical application value of ultrasound contrast on evaluating fallopian tube patency.Methods Ultrasound contrast examination was conducted on 84 patients suffering from infertility and the flowing status of contrast agent in the uterine cavity and the fallopian tube and the distribution condition in the pelvic cavity were observed under the real -time ultrasound to judge the patency condition of the fallopian tube.Results After 84 patients receiving ultrasound contrast,38 cases'bilateral fallopian tubes were unobstructed,26 cases'lateral fallopian tube were unobstructed and 20 cases'bilateral fallopian were obstructed.Comparing the result of ultrasound contrast with laparoscopy,the diagnosis accuracy was 89.5%,the specificity 86% and the sensitivity 94%.Conclusion Fallopian tube ultrasound contrast technique can make an accurate and objective evaluation on the fallopian tube patency,it is an effective method to check fallopian tube patency and it is of high clinical application value.

Objective To explore the effect of rehabilitation training on learning and memorial ability and long-term potentiation (LTP) in hippocampal region CA3 in rats with cerebral infarction. Methods 30 male rats were randomly divide into model group, rehabilitation training group and normal group with 10 cases in each group. Photochemical method was used to induce hippocampal infarction. The performance of Y-maze test and moving-back with current stimulation experiment were recorded. The increase rate of population spike (PS) in hippocampal region CA3 and PS latent period were compared. Results The frequency of training of Y-maze test was less after rehabilitation training, the latent period of moving-back with current stimulation experiment prolonged, and the PS latent period was shortened. Conclusion Rehabilitation training may strengthen the LTP effect in hippocampal region CA3, and improve the learning efficiency

Objective To study the different ultrasonic features in patients of polycystic ovary syndrome (PCOS) with or without obesity based on body mass index (BMI), and to investigate whether certain hormonal factors correlate with ovarian morphology and blood flow, and to discuss the role of ultrasound combined with hormone test in the diagnosis of obese PCOS. Methods One hundred and five women with PCOS were recruited. Patients were divided into two groups according to BMI;obese PCOS group (OB-PCOS, n=32, BMI≥25 kg/m2) and non-obese PCOS (NOB-PCOS, n=73, BMI<25 kg/m2). The ultrasonic parameters of follicle number (FN), ovarian volume (Vol), resistance index (RI) of ovarian stromal blood, RI of uterine artery and serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), the ratio of luteinizing hormone and follicle-stimulating hormone (LH/FSH), progesterone (P), estradiol (E2), free testosterone (FT), prolactin (PRL), sex hormoe binding globulin (SHBG), fasting plasma glucose (FPG), fasting insulin (FINS), the extent of insulin resistance and hyperandrogenism (HOMA-IR) were measured and compared. The correlation of the ultrasonic parameters and hormonal factors were analyzed. Results The Vol of OB-PCOS group was significantly higher than NOB-PCOS group [(12.25±4.89) ml vs (10.73±2.30) ml, t=2.20, P < 0.05]. FN and uterine artery RI of OB-PCOS group had a rising trend and RI of ovarian interstitial was on a reducing trend compared with NOB-PCOS group. But the differences were not statistically significant. The levels of FINS and HOMA-IR in OB-PCOS group [(14.82±6.45) mU/L and (3.91±3.30)] were significantly higher than those in NOB-PCOS group [(8.04±4.57) mU/L and (1.64±1.20)] (t=4.87, 3.47, respectively, both P < 0.01). And FSH in NOB-PCOS group was significantly higher than OB-PCOS group [(5.95±1.91) U/L vs (4.65±1.88) U/L, t=-2.77, P<0.01]. In POCS patients, FN was significantly associated with LH/FSH (r=0.35, P<0.01), and FT (r=0.38, P<0.01). Vol was significantly associated with LH/FSH, BMI, HOMA-IR and FPG (r=0.27, P<0.05;r=0.25, P<0.05;r=0.40, P<0.01;r=0.32, P<0.01). RI of ovarian stromal blood flow was significantly associated with SHBG (r=0.28, P<0.05). In OB-POCS group, RI of uterine artery was significantly associated with PRL (r=-0.58, P < 0.05). Vol was significantly associated with HOMA-IR (r=0.47, P < 0.05). In NOB-POCS group, FN was significantly associated with LH/FSH (r=0.33, P<0.05), and FT (r=0. 56, P<0.05). Vol was significantly associated with FT (r=0.31, P < 0.05). Conclusion There are some differences in the ultrasound and endocrine parameters between obese and non-obese PCOS patients, and some correlations exist between them.

In this study, hydrophilic matrix sustained release tablets of total lactones from Andrographis paniculata were prepared and the in vitro release behavior were also evaluated. The optimal prescription was achieved by studying the main factor of the type and amount of hydroxypropyl methylcellulose (HPMC) using single factor test and evaluating through cumulative release of three lactones. No burst drug release from the obtained matrix tablets was observed. Drug release sustained to 14 h. The release mechanism of three lactones from A. paniculata was accessed by zero-order, first-order, Higuchi and Peppas equation. The release behavior of total lactones from A. paniculata was better agreed with Higuchi model and the drug release from the tablets was controlled by degradation of the matrix. The preparation of hydrophilic matrix sustained release tablets of total lactones from A. paniculata with good performance of drug release was simple.
